Amebiasis is a common cause of dysentery in India and can have an atypical fulminant course with negative serological tests in immunosuppressed individuals such as chronic kidney disease (CKD). We present a patient of CKD on dialysis who presented with features of dysentery with negative blood and serology workup. The diagnosis of amebic colitis was made after colonoscopy and histopathology which revealed amebic trophozoites and her symptoms abated after appropriate therapy. This case report illustrates the need for colonoscopy and histopathology for definite diagnosis of fulminant presentation of amebic colitis in an immunosuppressed individual such as CKD.

| Introduction|| |
Amebiasis is a common cause of dysentery in India. Chronic kidney disease (CKD) patients due to their inherent immunosuppressed state do not mount a good immune response, and thus, may present as fulminant disease with atypical presentation with negative serological tests. Colonoscopy with histopathology is important to establish a diagnosis of amebiasis in this setting so as to institute appropriate therapy.
| Case Report|| |
A 63-year-old female, CKD on maintenance hemodialysis developed diffuse abdominal pain with fresh bleeding in stools, hemoglobin dropped from 10.9 g/dl to 6.4 g/dl, and coagulation profile was normal (platelets – 1.51 lac, prothrombin time-international normalized ratio – 1.16, activated partial thromboplastin time - 27.3/27.9–32.7). Stool culture, clostridium deficile toxin, amebic serology, and blood culture were negative. Ultrasound abdomen showed thickened bowel loops. Colonoscopy [Figure 1] revealed discrete medium to a large ulcer in the entire colon, normal intervening mucosa, and bulky ileocecal valve with ulcerations. A differential diagnosis of inflammatory bowel disease versus amebic colitis was kept and she was empirically started on metronidazole and mesalamine. Histopathology [Figure 2] and [Figure 3] revealed extensive areas of ulceration with acute inflammatory exudates and amebic trophozoites embedded within necrotic tissue suggestive of amebic colitis. Mesalamine was stopped; metronidazole was continued followed by luminal agents. She improved clinically with complete resolution of signs and symptoms.

| Discussion|| |
Entamoeba histolytica is the cause of amebiasis (amebic colitis), a protozoan disease, affecting large intestine, 40–50 million symptomatic cases reported annually worldwide. Poor sanitation leads to transmission of protozoan to humans through water contaminated with feces.
Amebic colitis presents typically with weight loss, cramping abdominal pain, and bloody diarrhea for the duration of up to several weeks. Penetration of intestinal mucous layer by trophozoites results in colitis.
Differential diagnosis of dysentery in this setting includes Shigella, Salmonella More Details, Campylobacter, Escherichia More Details coli, inflammatory bowel disease, ischemic colitis, diverticulitis, and arteriovenous malformation. Antigen detection and polymerase chain reaction are specific and sensitive means to detect E. histolytica in stool. In cases where stool tests for E. histolytica are negative or unavailable, colonoscopy may be helpful for diagnosis of amebic colitis.
Our patient had features of dysentery with abdominal pain, stool analysis, serology was negative, and cultures were sterile. In view of negative stool tests, colonoscopy was done which revealed multiple ulcers with intervening normal mucosa.
Histopathological findings of amebic colitis range from diffuse nonspecific mucosal thickening with or without ulcerations, focal ulcerations, classic flask-shaped lesions with ulceration extending through mucosa and muscularis into submucosa and necrosis and perforation of the intestine; with or without visualization of amebae. Visualization of amebae is aided by periodic acid-Schiff or immunoperoxidase and antilectin antibodies.
In this patient, biopsy was diagnostic with finding of amebic trophozoites. She improved following intravenous metronidazole therapy and luminal agents. CKD patients due to their inherent immunosuppressed state do not mount a good immune response and thus, may present as a fulminant disease with atypical presentation with negative serological tests. In these settings, colonoscopy and biopsy are important for definitive diagnosis so as to institute appropriate therapy.
