Cholera | Causes | Pathogenesis | Signs and Symptoms | Nursing Management

by

Cholera is a bacterial infection caused by the bacterium Vibrio cholerae. It typically spreads through contaminated water and food, particularly in areas with poor sanitation and hygiene practices. Cholera can lead to severe diarrhea and dehydration, and in severe cases, it can be life-threatening if not promptly treated. Symptoms of cholera include profuse, watery diarrhea, vomiting, and muscle cramps. Treatment usually involves rehydration therapy, including oral rehydration solution (ORS) or intravenous fluids, along with antibiotics to shorten the duration of illness and reduce the severity of symptoms. Prevention strategies include improving sanitation, ensuring access to clean drinking water, and promoting good hygiene practices such as handwashing. Vaccines are also available to provide protection against cholera in high-risk populations.

Incubation Period: Cholera has an incubation period ranging from a few hours to up to 5 days. During this time, individuals may be infected with the Vibrio cholerae bacterium but not yet display symptoms.

Transmission: The primary mode of transmission for cholera is the oral-fecal route, typically occurring through the ingestion of contaminated food and water. Poor sanitation and hygiene practices contribute to the spread of the disease, particularly in areas with inadequate access to clean water and sanitation facilities.

Causative Organism

Cholera is caused by the bacterium Vibrio cholerae. There are two main biotypes:

  1. Classical cholerae vibrio: This biotype of Vibrio cholerae is responsible for the majority of cholera cases worldwide.
  2. Haemolytic El Tor vibrio: This biotype is a variant of Vibrio cholerae that emerged in the 20th century and is associated with some cholera outbreaks.

Characteristics of Vibrio Cholerae:

  1. Shape: Vibrio cholerae is characterized by its comma shape, resembling a curved rod.
  2. Oxygen Requirement: It is an aerobic organism, meaning it requires oxygen to survive and grow.
  3. Gram Stain: Vibrio cholerae is Gram-negative, indicating that it does not retain the crystal violet stain in the Gram staining process.
  4. Spore Formation: It does not form spores, distinguishing it from certain other bacteria that can produce spores for survival.
  5. Motility: Vibrio cholerae is a motile organism, possessing both flagella and somatic antigens that enable it to move actively.
  6. Heat and Disinfectant Sensitivity: It is susceptible to heat, being killed at temperatures of 55°C for 15 minutes. Additionally, it can be effectively eliminated by phenolic and hypochlorite disinfectants.
  7. Environmental Survival: Vibrio cholerae can survive in aquatic environments for extended periods, entering a dormant state that allows it to persist until conditions become favorable for growth and reproduction.

Epidemiology:

Cholera predominantly affects individuals from low socioeconomic backgrounds residing in areas with poor sanitation, limited access to healthcare services, and unsafe water supplies. The disease is particularly prevalent in regions of Asia and Africa where these conditions are widespread. Cholera transmission occurs primarily through the ingestion of contaminated feces and water. Additionally, consumption of other perishable foods such as milk, cold-cooked dishes, and unwashed fruits and vegetables can also contribute to the spread of infection.

Pathogenesis:

Vibrio cholerae primarily resides in the gut and does not enter the bloodstream. It attaches to the mucosa of the small intestines using outer membrane proteins and flagella adhesions. The bacterium produces an enterotoxin that leads to excessive loss of fluid and electrolytes. This enterotoxin inhibits the absorption of sodium chloride, leading to its excretion along with water, potassium, and bicarbonate. Natural infection typically results in immunity to both the cholera toxin and bacterial surface antigens.

Signs and symptoms:

Evacuation Phase:

  1. Onset of diarrhea ranging from mild to acute, initially containing fecal matter but later becoming watery, often described as “rice water stool.”
  2. Projectile vomiting may accompany diarrhea.
  3. Severe dehydration occurs due to extensive fluid loss from diarrhea and vomiting.

Collapse Phase:

  1. Muscle cramps develop due to electrolyte imbalances resulting from fluid loss.
  2. Metabolic acidosis manifests with signs of air hunger, characterized by deep and sometimes rapid breathing.
  3. Hypovolemic shock ensues due to vascular depletion, leading to vascular collapse. Symptoms include hypotension, tachycardia, and impalpable pulses at the wrist, along with cold, clammy skin, and oliguria. Without intervention, shock can progress to acute renal failure and, potentially, death.

Recovery Phase:

As the patient enters the recovery phase, there is a noticeable improvement in their condition, and the signs and symptoms begin to subside.

  1. Resolution of Symptoms: The diarrhea and vomiting gradually diminish, and the patient experiences a reduction in the severity and frequency of bowel movements and episodes of vomiting.
  2. Hydration Restoration: With appropriate rehydration therapy and fluid replacement, the patient’s hydration status improves. Intravenous fluids or oral rehydration solutions help replenish lost fluids and electrolytes, aiding in the restoration of normal hydration levels.
  3. Regaining Strength: The patient starts to regain strength and energy as they recover from the debilitating effects of dehydration and metabolic disturbances. Muscle weakness and fatigue begin to diminish, allowing the patient to resume normal activities gradually.
  4. Normalization of Vital Signs: Vital signs, such as blood pressure, heart rate, and respiratory rate, stabilize and return to normal ranges as the patient’s condition improves.
  5. Resumption of Appetite: As the gastrointestinal symptoms subside, the patient’s appetite typically returns. They may start to tolerate oral intake better and resume eating a normal diet.

Diagnosis:

Clinical Diagnosis in Epidemics: In epidemic situations, a presumptive diagnosis of cholera is often based on clinical presentation or epidemiological factors. For instance, individuals aged 5 years or older who develop acute watery diarrhea with or without vomiting, particularly in areas where cholera outbreaks are likely to occur, may be clinically diagnosed with the disease.

Laboratory Diagnosis:

  1. Dark Field Microscopy: Examination of stool samples under dark field microscopy may reveal the characteristic darting movement of Vibrio cholerae. Inhibition of this movement by specific antisera (e.g., O1 antisera) provides strong supportive evidence for the diagnosis.
  2. Microbiological Culture: Stool, vomitus, or rectal swabs are collected for microbiological culture and sensitivity testing. This method confirms the presence of Vibrio cholerae in the samples, aiding in a definitive diagnosis.
  3. Immunofluorescent Assay: Immunofluorescent techniques allow for rapid diagnosis of cholera by detecting specific antigens associated with Vibrio cholerae in clinical specimens. This method offers a quick and efficient means of confirming the presence of the bacteria.

Management

Aims:

  1. Correcting Fluid and Electrolyte Imbalance: The primary aim is to restore normal fluid and electrolyte levels in the body to mitigate the effects of dehydration and electrolyte disturbances.
  2. Eliminating the Causative Organism: Efforts are focused on eradicating the Vibrio cholerae bacterium from the body to halt the progression of the disease and prevent further transmission.
  3. Preventing the Spread of Infection: Implementation of measures to contain and control the spread of cholera, including isolation of affected individuals, proper sanitation practices, and hygiene protocols to minimize the risk of transmission to others.
  4. Preventing Complications from Fluid and Electrolyte Loss: Proactive measures are taken to prevent and manage complications arising from severe dehydration and electrolyte imbalances, such as hypovolemic shock, metabolic acidosis, and organ failure. This involves prompt rehydration therapy and close monitoring of the patient’s clinical status.

Therapy:

Correction of Fluid and Electrolyte Imbalance: Immediate initiation of intravenous fluid therapy is essential for correcting fluid and electrolyte imbalances. Use fluids such as Ringer’s lactate or normal saline. If the patient is able to drink, administer oral rehydration solution (ORS) while setting up the intravenous drip.

In cases of severe dehydration, administer rapid intravenous fluid resuscitation, giving 30 mL/kg body weight within the first 30 minutes, followed by 70 mL/kg body weight over the next 2½ hours. The goal is to restore normal hydration and acid-base balance within 2-3 hours. Subsequently, continue rehydrating the patient at a slower rate until the pulse and blood pressure return to normal.

Once the patient is capable of oral intake, provide oral rehydration at a rate of 5 mL/kg body weight per hour (250 mL/hr). Monitor vital signs every 30 minutes during fluid resuscitation, adjusting the rate of infusion if signs of circulatory overload are observed.

Monitor urine output hourly, aiming for a normal range of 30–40 ml/hr. If urine output is reduced, indicating potential acute renal failure, prompt medical intervention is necessary.

Administer ORS as soon as the patient is able to drink orally. Maintain fluid replacement by accounting for losses from stool. Oral rehydration should be encouraged and administered as needed.

Antimicrobial Agents:

  1. Tetracycline: Administer 500mg orally four times a day for a duration of three days. Tetracycline is effective in treating cholera and helps eradicate Vibrio cholerae from the body.
  2. Doxycycline: A single dose of 300mg is considered the drug of choice for cholera treatment. Doxycycline exhibits potent antibacterial activity against Vibrio cholerae and aids in resolving the infection.
  3. Cotrimoxazole: Prescribe 960mg orally twice daily for a duration of three days. Cotrimoxazole, a combination of sulfamethoxazole and trimethoprim, is another option for treating cholera effectively.
  4. Ciprofloxacin: Administer 500mg orally twice daily for three days. Ciprofloxacin is a broad-spectrum antibiotic with activity against Vibrio cholerae, making it suitable for cholera treatment.
  5. Erythromycin: Prescribe 500mg orally four times a day for three days. Erythromycin is effective in treating cholera and can be used as an alternative antimicrobial agent in cases where other antibiotics are not suitable.

These antimicrobial agents help eliminate the causative organism, Vibrio cholerae, from the body, contributing to the resolution of cholera infection and preventing its complications. It is crucial to adhere to the prescribed dosage and duration of treatment to ensure effectiveness and minimize the risk of antimicrobial resistance.

Dysentery | Causes | Pathophysiology | Signs and Symptoms | Nursing Management

by

Dysentery is a well-known condition. It is characterized by the frequent passage of small, watery stools that often contain blood and mucus. This condition affects the large intestine and is accompanied by severe abdominal cramps. It can manifest as either an acute or chronic disease.

Causes of dysentery

Dysentery can be caused by various factors, including:

  1. Bacterial Infections: Pathogenic bacteria such as Shigella, Salmonella, Campylobacter, and Escherichia coli can cause dysentery through contamination of food or water sources.
  2. Parasitic Infections: Protozoa like Entamoeba histolytica can lead to dysentery when ingested through contaminated food or water.
  3. Viral Infections: Certain viruses, such as the norovirus, can cause dysentery-like symptoms, particularly in outbreaks or crowded environments.
  4. Poor Hygiene Practices: Inadequate sanitation, improper handwashing, and unsanitary living conditions can contribute to the spread of dysentery-causing pathogens.
  5. Contaminated Food and Water: Consumption of contaminated food or water, particularly in regions with inadequate sanitation, is a common cause of dysentery.
  6. Travel to Endemic Areas: Traveling to regions where dysentery is endemic increases the risk of exposure to the pathogens responsible for the condition.
  7. Weakened Immune System: Individuals with compromised immune systems, such as those with HIV/AIDS or undergoing immunosuppressive therapy, are more susceptible to developing dysentery.
  8. Poor Food Handling: Improper handling, storage, or preparation of food can lead to bacterial contamination and subsequent dysentery.

Types of dysentery

Dysentery is a term used to describe intestinal inflammation, particularly of the colon, resulting in severe diarrhea with blood and mucus in the feces. It is most commonly caused by bacterial or parasitic infections. There are two main types of dysentery:

  1. Bacterial Dysentery: This type of dysentery is caused by bacterial infections, most commonly by strains of bacteria such as:
    • Shigella: Shigellosis is caused by the Shigella bacteria and is a common cause of bacterial dysentery, especially in developing countries.
    • Campylobacter: Campylobacteriosis can also lead to dysentery-like symptoms, including bloody diarrhea.
    • Escherichia coli (E. coli): Certain strains of E. coli, such as E. coli O157:H7, can cause dysentery when ingested.
  2. Amoebic Dysentery: Amoebic dysentery is caused by the protozoan parasite Entamoeba histolytica. This type of dysentery is more common in tropical and subtropical regions and can lead to severe complications if left untreated.

Bacillary dysentery is a condition marked by acute inflammation and ulceration of the large intestine, manifesting as frequent small bowel movements containing blood and mucus in the stool. It is caused by non-motile gram-negative bacteria belonging to the genus Shigella. Shigella is classified into four strains:

  • Shigella flexneri,
  • Shigella boydii,
  • Shigella dysenteriae,
  • Shigella sonnei.

These types of dysentery share similar symptoms, including diarrhea, abdominal pain, fever, and sometimes dehydration. However, the treatment may vary depending on the specific cause, with bacterial dysentery often treated with antibiotics and amoebic dysentery treated with anti-parasitic medications. A proper diagnosis is essential for effective treatment.

Predisposing Factors

The predisposing factors contributing to the occurrence of dysentery can be summarized by the “6 F’s”: Formites, Food, Faeces, Fingers, Fluids, and Flies. Addressing these factors effectively can help mitigate the problem. These factors include:

i. Poor feeding practices: This encompasses the improper handling of feeding bottles for infants, which may become contaminated if not cleaned adequately. Additionally, consuming unboiled or improperly prepared foods increases the risk of dysentery transmission.

ii. Inadequate personal hygiene: This involves insufficient attention to hand hygiene, such as inadequate handwashing practices and neglecting to trim and maintain fingernails. Poor personal hygiene can facilitate the transmission of pathogens responsible for dysentery.

iii. Unsafe water sources and storage: The lack of access to safe drinking water, coupled with inadequate treatment and storage facilities, can expose individuals to waterborne pathogens, including those causing dysentery.

iv. Inadequate sanitation: This encompasses issues such as the presence of rubbish pits or dumping sites in close proximity to living areas, as well as poorly maintained sewerage lines. These conditions create environments conducive to the proliferation and spread of disease-causing organisms.

v. Overcrowding: Overcrowded living conditions facilitate the rapid spread of infectious diseases like dysentery. Close contact between individuals increases the likelihood of transmission, particularly in settings where sanitation and hygiene practices are suboptimal.

Epidermiology

Bacillary dysentery is predominantly found in unhygienic tropical regions; however, due to its ease of transmission, sporadic outbreaks can occur worldwide. The disease is particularly prevalent among densely populated communities, including nursing homes and large institutions where overcrowding is common.

Mode of Transmission 

When examining this picture, one immediately thinks about the mode of transmission of dysentery. Shigella, the causative agent, spreads primarily through the fecal-oral route. The bacteria are expelled in feces, and inadequate sanitation and hygiene practices can lead to contamination of food and water sources. Flies further exacerbate the problem by frequently spreading the bacteria to food, making them a significant mode of transmission for dysentery. Figure 8 depicts the transmission pathway of dysentery, highlighting the importance of proper sanitation and hygiene measures in preventing its spread. The incubation period of Shigella is typically 1 to 7 days.

Pathophysiology

Dysentery, particularly bacillary dysentery caused by Shigella species, involves a complex series of events within the gastrointestinal tract. It begins with the ingestion of Shigella bacteria, often through contaminated food, water, or contact with infected individuals. Upon reaching the lower intestine, Shigella bacteria adhere to and invade the epithelial cells lining the intestinal mucosa. This invasion triggers a vigorous inflammatory response characterized by the release of pro-inflammatory cytokines and chemokines, recruiting immune cells such as neutrophils and macrophages to the site of infection.

As Shigella infiltrates the intestinal tissue, it causes damage to the epithelial cells, disrupting the mucosal barrier. This damage facilitates the release of toxins produced by Shigella species, including Shiga toxin, which further exacerbates tissue damage and inflammation. Consequently, mucosal ulceration occurs in the colon, resulting in the formation of erosions or ulcers in the intestinal lining. These ulcers contribute to the hallmark symptoms of dysentery, such as abdominal pain, cramping, frequent and urgent bowel movements, and the passage of bloody and mucoid stools.

In severe cases, dysentery can lead to complications such as dehydration due to fluid loss from diarrhea, electrolyte imbalances, systemic spread of infection leading to sepsis, and, rarely, the development of conditions like reactive arthritis or hemolytic uremic syndrome (HUS). Overall, understanding the pathophysiology of dysentery is crucial for the development of effective prevention strategies and treatments aimed at mitigating the impact of this infectious disease on affected individuals and communities.

Signs and Symptoms

  • Dysentery presents with a sudden onset of symptoms.
  • Fever is common due to infection and inflammation.
  • Dehydration signs, like loss of skin turgor, may occur due to diarrhea; however, dehydration may not always be present as stool frequency increases.
  • Abdominal discomfort is an early symptom, likely from irritation of the gastrointestinal tract’s mucosal lining by the bacteria.
  • Nausea and vomiting may result from irritation of the stomach’s mucosal lining.
  • Colicky abdominal pains are common, likely due to the inflammatory reaction in the intestinal mucosal lining.
  • Bloody diarrhea is characteristic, resulting from damage to the large intestine’s mucosal lining during inflammation, potentially damaging capillaries.
  • Bloody diarrhea often accompanies urgency and tenesmus, with urgency being the frequent urge to defecate even with small stool amounts passed, and tenesmus being the painful, ineffective straining to empty the bowels.

Management:

  1. Correct electrolyte and fluid imbalance.
  2. Eliminate the causative organism.
  3. Prevent and manage complications.

Investigations:

  • Microscopic examination of a fresh stool specimen and rectal swab for culture and sensitivity. Stool should be cultured promptly after collection. Detection of the organism in stool confirms diagnosis.
  • Immunofluorescent techniques can be used to detect the organism in stool.
  • Sigmoidoscopy can reveal a red, bleeding mucosa with patches of necrotic membrane, which may separate to leave ulcerated areas.

Therapy:

Fluid and electrolyte replacement: Oral rehydration is typically necessary to address fluid and electrolyte imbalances. However, each patient should undergo assessment to determine the extent of dehydration and receive appropriate fluid replacement therapy.

Drugs: Antibiotics are prescribed to shorten the duration of illness and prevent relapse. Any of the following antibiotics can be given while awaiting the results of culture and sensitivity:

  • Nalidixic acid: 1g orally four times a day for 7 to 14 days.
  • Ciprofloxacin: 500mg orally twice daily for 5 days.
  • Trimethoprim-Sulfamethoxazole (Septrin, Co-trimoxazole): 960mg orally twice daily for 5 days.
  • Chloramphenicol: 50 to 100mg per kilogram of body weight orally four times a day for 5 days.
  • Ampicillin: 500mg orally four times a day for 5 days.

Amoebic dysentery

Amoebic dysentery, also known as amoebiasis, is the second type of dysentery caused by an infection with the pathogenic amoeba Entamoeba histolytica. This chronic enteric infection is brought about by a protozoan organism known as Entamoeba histolytica, which is a single-celled parasite.

  • Cause: Amoebic dysentery is caused by the protozoan parasite Entamoeba histolytica.
  • Predisposing Factors: Similar to bacillary dysentery, predisposing factors include poor sanitation, inadequate hygiene practices, contaminated food and water sources, overcrowding, and low socioeconomic conditions.
  • Epidemiology: Entamoeba histolytica has a global distribution and is endemic in regions with poor sanitation and low socioeconomic status. The use of night soil (human feces used as fertilizer) in agriculture facilitates the spread of the disease. The organism is acquired through the ingestion of cysts.
  • Mode of Transmission: Transmission occurs primarily through the fecal-oral route, where ingestion of contaminated food or water containing cysts leads to infection. Vectors such as flies, cockroaches, and rodents can carry cysts and contaminate food and drink, further spreading the disease.
  • Incubation Period: The incubation period for amoebic dysentery can vary widely, ranging from 2 weeks to years. Human beings serve as the principal reservoirs and carriers of the parasite, contributing to its transmission.

Pathophysiology:

When ingested, cysts of Entamoeba histolytica enter the alimentary tract via the mouth and proceed to the stomach, where they undergo excystation during digestion. Motile trophozoites are released, which then multiply. These trophozoites proceed to invade and ulcerate the intestinal mucosa of the large bowels, forming flask-like ulcers. Additionally, some of the amoebae may travel through the mesenteric artery, reaching the liver. In the liver, they cause total destruction, resulting in amoebic hepatocellular necrosis and the formation of liver abscesses.

Signs and Symptoms:

  • The onset of symptoms is gradual and typically involves abdominal discomfort.
  • Other signs and symptoms may include:
    • Mildly loose stools or frank diarrhea, sometimes with blood and mucus. Diarrhea may alternate with episodes of constipation.
    • Tenderness may develop over the caecum, transverse colon, or sigmoid.
    • Fever may be present.
    • Abdominal pains that may occur intermittently.
    • In cases of hepatic amoebiasis, symptoms may include body malaise, fluctuating temperature, sweating, and an enlarged, tender liver.
    • Foul-smelling stool.
    • Weight loss in chronic cases.

Investigations:

  • Stool microscopy, culture, and sensitivity testing (m/c/s) can help identify the presence of Entamoeba histolytica.
  • History of blood-stained stool is essential for diagnosis.
  • Physical examination may reveal signs of dehydration.
  • Rectal swab culture can aid in confirming the presence of the parasite.
  • Hemoglobin (Hb) levels in blood can indicate anemia, which may occur due to chronic infection.
  • Sigmoidoscopy can visualize ulcers in the intestinal mucosa.
  • Liver scan may be conducted to detect liver abscesses.

Treatment:

The disease is managed with the following interventions:

  • Flagyl (metronidazole) at doses of 200-400mg three times daily.
  • Septrin (trimethoprim-sulfamethoxazole) at a dose of 960mg twice daily for 5-7 days.
  • Furamide (diloxanide furoate) at a dose of 500mg three times daily for 10 days.
  • For hepatic amoebiasis, Flagyl (metronidazole) and Chloroquine are given at a dose of 600mg once daily for 2 days, followed by 300mg once daily for 21 days.
  • Panadol (acetaminophen) may be prescribed for fever and pain relief.
  • Intravenous fluids, such as Ringer’s lactate, may be administered to manage dehydration.

Nursing Care of Dysentery:

The goals of nursing care include:

  • Preventing further transmission of infection.
  • Replenishing lost fluids and electrolytes.
  • Preventing complications such as shock.

Environment:

  • Admit the patient to an isolation room separate from other patients to prevent the spread of infection. The room should be well-lit for easy observation and have good ventilation to promote air circulation. Position the patient near the toilet for convenience. Ensure essential equipment such as drip stands, intravenous sets, and observation trays are readily accessible within the patient’s environment.

Observation:

  • Monitor the patient’s general condition regularly. Frequently monitor vital signs such as temperature, pulse, respiration, and blood pressure. The frequency of observations depends on the patient’s condition. Assess the quality and quantity of stool passed by the patient. Monitor intake and output and record on fluid balance charts. Evaluate stool characteristics including amount, consistency, and color, and report any abnormalities. Watch for signs of dehydration such as loss of skin elasticity, sunken eyes, thirst, and dry mucous membranes of the mouth.

Infection Prevention:

  • Isolate the patient away from other patients to prevent the spread of infection. Individuals coming into contact with the patient should adhere to isolation protocols, including wearing gowns and masks when entering the room and washing hands before and after attending to the patient. Limit visitors to reduce the risk of infection transmission. Disinfect patient linens with a solution of JIK 1:6 and label them as “infectious” before sending them to the laundry. Avoid mixing this linen with other ward linens. Administer prescribed medication to treat the causative organism. Disinfect all utensils used by the patient to prevent contamination and further spread of infection.

Nutrition:

Provide the patient with plenty of fluids to ensure hydration, along with a gentle diet that is free from irritants. If the patient is unable to consume food or fluids orally due to their condition, initiate intravenous fluid therapy to maintain hydration and electrolyte balance. It’s essential to closely monitor both the intake and output of fluids. Keep detailed records of the amount and type of fluids administered intravenously, noting the start time of IV fluid therapy and the date it commenced. Additionally, record the patient’s oral intake and output to accurately assess their fluid balance and nutritional status.

Hygiene:

Depending on the patient’s condition, offer assistance with a bed bath to enhance comfort, preserve self-esteem, and eliminate dirt. Provide oral care assistance to prevent complications arising from poor oral hygiene, such as mouth infections. This also aids in promoting salivation, particularly crucial when the patient experiences dry mouth due to significant fluid loss. Promptly change soiled linens as needed, ensuring they are disinfected with a solution of Jik 1:6 before being sent to the laundry. This helps maintain cleanliness and reduce the risk of infection. Thoroughly clean the perineal area to uphold hygiene standards and minimize the risk of infections in this sensitive region.

Psychological Care:

Patients with dysentery may experience feelings of neglect, therefore, it’s essential for nurses to provide appropriate psychological support to alleviate anxiety. Educate the patient about the disease process, including its cause, mode of transmission, signs and symptoms, treatment, and potential complications. Explain the necessity of isolation to the patient, emphasizing its role in preventing the spread of infection. Similarly, inform significant others why visitation is restricted. Ensure that any procedures performed on the patient are thoroughly explained to gain their cooperation. Encourage patients to ask questions, and respond truthfully to address their concerns. This fosters trust and understanding between the patient and healthcare provider.

Medication Management:

Administer medications as prescribed by the healthcare provider, ensuring adherence to dosage and timing instructions. Monitor the patient closely for any adverse reactions or side effects that may occur as a result of medication administration. Additionally, administer fluids to the patient based on their individual condition and hydration status. Adjust fluid administration according to the patient’s fluid balance and response to treatment. Regularly assess the patient’s response to both medication and fluid therapy, and promptly report any concerning symptoms or changes in condition to the healthcare team. This proactive approach helps to ensure effective management of dysentery and promotes optimal patient outcomes.

Elimination Management:

Monitor and record the patient’s intake and output meticulously to track fluid balance and hydration status accurately. Observe stool characteristics, including volume, consistency, contents, and odor, to assess gastrointestinal function and identify any abnormalities. Initially, provide a bedpan for elimination, ensuring patient comfort and dignity. As the patient’s condition improves, encourage and assist them to use the toilet independently. This gradual transition promotes patient mobility and autonomy while maintaining hygiene and minimizing discomfort.

Prevention and Control of Dysentery:

Based on our discussion regarding the mode of transmission and predisposing factors of dysentery, several measures can be implemented to prevent its occurrence:

  1. Improved Environmental Sanitation: This includes:
  • Providing safe and sufficient water supply to communities.
  • Ensuring the safe and proper disposal of human waste through the use of pit latrines or toilets.
  • Implementing measures to safeguard food against fecal contamination.
  • Offering information, education, and communication campaigns about dysentery to raise awareness and promote preventive measures.
  • Discouraging the use of untreated human waste as fertilizer or manure, which can contribute to the spread of the disease.

Early Diagnosis and Treatment of Cases and Carriers:

  • Ensure prompt detection and provide appropriate and adequate treatment for both cases and carriers of dysentery.
  • Conduct regular screening of food handlers to identify and prevent potential sources of infection.

Improved Personal and Communal Hygiene:

  • Encourage adequate handwashing with soap and running water after using the toilet and before handling or consuming food.
  • Promote the use of pit latrines or toilets for defecation to prevent fecal contamination of the environment.
  • Prohibit children from defecating on the ground; instead, use toilet training pots and disinfect them after each use. Dispose of children’s stools in the toilet or pit latrine.
  • Boil water for drinking and washing vegetables and fruits to eliminate potential sources of contamination.
  • Avoid consuming vegetable and fruit salads, which may pose a risk of transmitting infection if not properly washed or cooked.

Complications of Dysentery:

  1. Perforation of the colon due to ulceration: Ulcers formed in the colon may lead to perforation, allowing the contents of the colon to spill into the abdominal cavity.
  2. Peritonitis due to perforation: If the colon perforates, the resulting spillage of intestinal contents can cause peritonitis, leading to severe abdominal inflammation and infection.
  3. Rectal prolapse due to tenesmus: Persistent straining during bowel movements (tenesmus) can lead to rectal prolapse, where the rectum protrudes through the anus.
  4. Hematogenous dissemination of the Shigella bacteria (rare): In some cases, Shigella bacteria may spread through the bloodstream, causing abscesses in various organs and potentially leading to meningitis.
  5. Acute, nonsuppurative arthritis: Large weight-bearing joints may become inflamed during the recovery phase, resulting in acute arthritis.
  6. Conjunctivitis, iritis, and peripheral neuropathy (rare): Rare complications may include inflammation of the eyes (conjunctivitis and iritis) and damage to peripheral nerves.
  7. Hemolytic uremic syndrome (7-10 days after onset): A severe complication characterized by acute kidney failure, low platelet count, and red blood cell breakdown.
  8. Toxic megacolon: The colon may become massively dilated due to inflammation, leading to life-threatening complications.
  9. Hemiplegia: In rare cases, dysentery may lead to paralysis affecting one side of the body (hemiplegia).
  10. Encephalopathy: Severe dysentery can cause brain dysfunction, leading to encephalopathy and neurological symptoms.
  11. Septicemia: The presence of pathogens in the bloodstream can lead to systemic infection and septicemia.
  12. Hyponatremia: Imbalances in electrolytes, such as low sodium levels, may occur due to excessive dehydration from diarrhea.
  13. Reiter’s syndrome: A reactive arthritis that can develop following an infection, characterized by joint pain, eye inflammation, and urinary tract symptoms.
  14. Liver abscess: Shigella infection may lead to the formation of abscesses in the liver, causing abdominal pain and other symptoms.
  15. Renal failure: Severe dehydration resulting from dysentery can lead to kidney failure due to reduced blood flow and electrolyte imbalances.

Crohn’s Disease | Causes | Pathophysiology | Nursing Management

by

Crohn’s disease is a chronic inflammatory condition of the gastrointestinal system, primarily impacting the distal ileum and colon. However, it can also affect any part of the digestive tract, from the mouth to the anus. This disorder is characterized by nonspecific inflammation, and its exact cause remains unknown. Crohn’s disease manifests as an idiopathic inflammatory process that can involve any segment of the gastrointestinal tract.

Epidemiology

Crohn’s disease can develop at any age, but it most commonly occurs between 25 and 30 years old. Both men and women are affected, with a slightly higher incidence among women. One-third of cases primarily involve the small bowel, often affecting the terminal ileum (ileitis). Approximately half of cases involve both the small bowel and colon, with the terminal ileum and adjacent proximal ascending colon being most commonly affected (ileocolitis). In 15-20% of cases, only the colon is affected.

Causes

The exact cause of Crohn’s disease remains unknown, but it is associated with several factors:

  • Genetic Factors: Crohn’s disease can have a familial predisposition, with certain genes inherited from parents increasing the risk of developing the condition.
  • Immune Disorders: Inflammation in Crohn’s disease may result from immune system dysfunction, leading it to mistakenly attack the normal flora of the gastrointestinal tract.
  • Previous Infection: Prior infections may trigger an abnormal immune response, contributing to the development of Crohn’s disease.
  • Smoking: Smokers with Crohn’s disease typically experience more severe symptoms compared to non-smokers.

Pathophysiology

Crohn’s disease can affect any part of the gastrointestinal (GI) tract, but it is most commonly observed in the terminal ileum, jejunum, and colon. The inflammation extends through all layers of the bowel wall (transmural). Typically, affected areas are not continuous, with segments of normal bowel interspersed between diseased portions. Ulcerations in Crohn’s disease are often deep and longitudinal, penetrating between islands of inflamed, edematous mucosa, resulting in the characteristic cobblestone appearance. Thickening of the bowel wall and narrowing of the lumen occur, leading to the development of strictures. Additionally, abscesses or fistula tracts may form, connecting with other loops of the bowel, skin, bladder, rectum, or vagina.

Clinical Manifestations

The manifestations of Crohn’s disease depend primarily on:

  • The anatomical site of involvement
  • The extent of the disease process
  • The presence or absence of complications

Common symptoms include:

  • Crampy abdominal pains caused by the intestines’ inability to transport gastrointestinal products through constricted lumens.
  • Chronic diarrhea resulting from continuous irritating discharge emptied into the colon from swollen intestines, often accompanied by blood.
  • Weight loss due to malabsorption and reduced food intake.
  • Fever, indicating infection.
  • Nausea and vomiting, which may signal the onset of small bowel obstruction.
  • Constipation: While most patients experience diarrhea, some may suffer from constipation due to inflammation around the anus, making defecation difficult.

Management

Aims

  1. Control the inflammatory process.
  2. Relieve symptoms.
  3. Correct metabolic and nutritional problems and promote healing.

Diagnostic Studies

  • Proctosigmoidoscopy: is typically the initial procedure to assess inflammation in the rectosigmoid area.
  • Stool Occult Blood Test.
  • Barium Enema: useful for identifying strictures and fissures.
  • Small Bowel X-ray: Can reveal irregular mucosa, ulcerations, and stiffening.
  • Sigmoidoscopy and colononoscopy: These procedures show patchy areas of inflammation.
  • Biopsy: Obtained during sigmoidoscopy, it reveals granulomatous tissue.
  • Blood tests: These may demonstrate an increased white blood cell count, a reduced erythrocyte sedimentation rate (ESR), and a decreased hemoglobin level.

Drug Therapy

While there is no specific therapy for Crohn’s disease, the following drugs may help manage symptoms:

  1. Corticosteroids (e.g., Prednisolone):
    • Dosage: Prednisolone 5–60 mg daily orally, given as a single dose or in divided doses. The maximum daily dose is 250mg.
    • Mode of Action: stimulates the synthesis of enzymes to decrease the inflammatory response.
    • Side Effects: suppression of the immune system, resulting in lymphocytopenia.
  2. Aminosalicylates (e.g., Sulfasalazine):
    • Dosage: Initial 3–4 g orally daily in divided doses, followed by a maintenance dose of 2g orally daily in divided doses.
    • Mode of Action: Believed to be metabolized by intestinal flora in the colon, producing anti-inflammatory and antibacterial effects.
    • Side Effects: reduced appetite, stomatitis, vertigo.
  3. Antibiotics (e.g., Metronidazole):
    • Dosage: 200–400 mg orally three times daily for 7–10 days.
    • Mode of Action: Bactericidal action by inhibiting bacterial DNA synthesis.
    • Side Effects: dry mucous membranes, metallic taste.
  4. Anti-Diarrheals (e.g., Loperamide):
    • Dosage: 4mg initially orally, then 2mg per loose stool. The maximum dose is 16mg in 24 hours.
    • Mode of Action: Reduces intestinal motility and fluid secretion.
    • Side Effects: constipation, abdominal pain, dry mouth, drowsiness.
  5. Analgesics (e.g., Paracetamol):
    • Dosage: 500–1000 mg orally three times daily.
    • Mode of Action: non-narcotic analgesic, antipyretic, and anti-inflammatory.
    • Side Effects: Rare, but may include nausea, vomiting, and liver damage.

Other measures include:

Malabsorption Syndrome | Etiology, Nursing Care Management

by

Introduction

Malabsorption syndrome refers to a group of disorders characterized by the inability of the digestive system to properly absorb nutrients from food. This can lead to deficiencies in essential vitamins, minerals, and other nutrients, causing various symptoms and complications. Common causes include gastrointestinal diseases such as celiac disease, Crohn’s disease, and pancreatic insufficiency. Symptoms may include diarrhea, weight loss, fatigue, and nutritional deficiencies. Treatment typically involves addressing the underlying cause and managing symptoms through dietary changes, supplements, and medication.

Etiology

The root cause of malabsorption syndrome lies in the inadequate absorption of essential nutrients due to various diseases. This can stem from issues in digestion, where nutrients aren’t properly broken down for absorption, or from difficulties in transporting digested nutrients across the brush border of the intestinal villi.

Diseases contributing to malabsorption include:

  1. Celiac disease
  2. Dermatitis herpetiformis
  3. Tropical sprue
  4. Bacterial overgrowth
  5. Whipple’s disease (resulting in villi growth impairment)
  6. Short-bowel syndrome
  7. Lactase deficiency
  8. Parasitic infestations like Giardia intestinalis.

The classification

The classification of malaasorption syndrome involves categorizing it based on the underlying causes and mechanisms. It can be broadly classified into two main types:

  1. Primary Malabsorption: This type occurs due to intrinsic defects within the digestive system, such as enzyme deficiencies or structural abnormalities in the intestinal lining. Examples include:
    • Celiac disease
    • Dermatitis herpetiformis
    • Short-bowel syndrome
  2. Secondary Malabsorption: This type is secondary to other medical conditions or factors that affect the absorption process, such as inflammation, infection, or surgical interventions. Examples include:
    • Tropical sprue
    • Bacterial overgrowth
    • Whipple’s disease
    • Lactase deficiency
    • Parasitic infestations, like Giardia intestinalis

Clinical Manifestations

Patients admitted to the hospital with malabsorption may present with the following features:

  1. Steatorrhea: excretion of more than 7g of fat daily in feces. Stools are typically pale, bulky, foul-smelling, and difficult to flush.
  2. Wasting: Failure to absorb essential nutrients leads to muscle wasting and weight loss. However, weight loss may not be apparent due to ascites and/or edema.
  3. Abdominal Distension: Increased bulk of intestinal contents and gas production can cause abdominal distension, accompanied by borborygmi (audible bowel sounds) and flatulence. Patients may experience abdominal discomfort.

Signs and Symptoms

Signs and Symptoms of Specific Deficiencies in Malabsorption:

  1. Fatigue: resulting from anemia and/or hypokalemia.
  2. Edema: due to hypoproteinemia and/or anemia.
  3. Tetany: caused by hypocalcemia.
  4. Hemorrhage: manifested as ecchymosis or purpura due to vitamin K deficiency.
  5. Anemia: results from iron deficiency.
  6. Decreased Libido.
  7. Glossitis and stomatitis result from deficiencies in folic acid and vitamin B.
  8. Bone Conditions: include osteoporosis, osteomalacia, and bone pain due to hypocalcemia and vitamin D deficiency.
  9. Increased Susceptibility to Infections: Due to globulin deficiency.
  10. Pigmentation of Skin and Mucous Membranes: Resulting from Hypoadrenalism.
  11. Hypotension, hypothermia, and inhibition of growth: due to depression of endocrine activity.
  12. Mental changes are particularly observed in gluten enteropathy.

Diagnosis

  1. Stool Analysis: Checking for bacterial growth and parasites, such as isolating Giardia lamblia cysts.
  2. Jejunal Biopsy: Obtaining mucosal samples via jejunoscopy to assess for malignancy or villi atrophy.
  3. Radiological Tests:
    • Ultrasound Scan
    • Computed Tomography (CT) Scan
    • Magnetic Resonance Imaging (MRI)
    • Barium Meal: Revealing dilation, segmentation, and loss of normal appearance in the small intestine, particularly the jejunum.
  4. Complete Blood Cell Count (CBC): To screen for anemia.
  5. Ultrasound Scan: May detect pancreatic or intestinal tumors.

Medical and Nursing Management

  1. Address the underlying cause: Treat or remove the primary cause, such as implementing a gluten-free diet for celiac disease or administering pancreatic extract for chronic pancreatic disease. Antibiotic therapy may be needed for conditions like diverticulosis.
  2. Compensate for malabsorption: In cases where specific treatment is not feasible, like after extensive stomach or intestine resections, focus on increasing the intake of essential nutrients and calories to overcome malabsorption.
  3. Correct deficiencies: Replace specific deficiencies identified through intravenous therapy when necessary to ensure proper nutrient levels.
  4. Alleviate symptoms: Implement strategies to reduce symptoms associated with steatorrhea, such as dietary modifications or medication.

Drugs

The medications prescribed for patients with malabsorption will depend on the underlying cause and any identified deficiencies. For example:

  • Antibiotics: Metronidazole is commonly used.
    • Mechanism of action: It is bactericidal, inhibiting bacterial DNA synthesis and leading to bacterial death.
    • Dosage: Typically 200–400 mg three times a day orally for 7–10 days.
    • Side effects: May include dry mucous membranes and a metallic taste.

Management:

A. Diet:

  • Gluten-free diet for celiac disease.
  • Low-fiber diets.
  • Incorporation of low-fat sources such as medium-chain triglycerides.
  • Avoidance of irritants like spicy foods.

B. Parenteral Fluids and Feeding:

  • Total parenteral nutrition via a central venous line may be necessary for severe cases.

Supplementation:

  • Vitamin B12 injections and oral iron supplements may be required.
  • Enzyme replacement therapy may be prescribed for those lacking intestinal enzymes.
  • Anti-spasmodic medications can help reduce abdominal cramping and diarrhea.

Specific Conditions:

  • Individuals with cystic fibrosis or chronic pancreatitis may need pancreatic supplements.
  • Those with lactose intolerance or non-tropical sprue (gluten enteropathy) should modify their diets to avoid triggering foods.

Once an oral diet is well tolerated, patients are typically prescribed a high-protein, low-fat, high-calorie diet supplemented with additional nutritional supplements. Specific dietary plans, such as a gluten-free diet for individuals with celiac disease, should be implemented as needed. Nurses play a crucial role in educating patients about the significance of adhering to their prescribed diet and ensuring compliance. They should assist patients in understanding the importance of their diet regimen and encourage consistent intake. Additionally, maintaining strict records of fluid intake and food consumption through fluid balance and food intake charts is essential.

Specific nursing management:

When caring for patients with malabsorption syndrome, nurses should employ a problem-solving approach such as the nursing process due to the diverse causes and severity levels of the syndrome. The main areas of assessment include:

  1. Management of Diarrhea and Steatorrhea-Related Problems:
    • Addressing issues like incontinence, perianal excoriation, and fatigue.
  2. Ensuring Adequate Nutritional Intake:
    • Focusing on strategies to ensure patients receive sufficient nourishment despite malabsorption challenges.
  3. Psychological Assessment:
    • Assessing for signs of depression, grief, or anger, which may arise from the loss of normal health,.

In addition to these assessments, nurses should provide comprehensive general care to severely ill patients who require complete bed rest. Special attention should be given to oral hygiene, pressure area care, and promoting deep breathing exercises to maintain overall well-being.
