A total of 47 patients with toxoplasmosis (21 cases) with amoebic liver abscess (14 cases) and with giardiasis (12 cases) as well as 14 healthy control were subjected to thorough history taking, clinical examination, stool & urine analysis, complete blood picture, ESR, C-reactive protein, ASO, widal test, blood cultures, liver function tests, serum creatinine, hepatitis viral markers, rheumatoid factor, auto-antibodies, stool culture, rectal snip, chest X-ray, abdominal sonar, level of serum adhesion molecules (sICAM-1, sELAM-1), ELISA detection of Toxoplasma antibodies in serum, liver biopsy, detection and counting of Giardia cysts. In toxoplasmosis group, highly significant increase in serum levels of sICAM-1 (P<0.01) and significant increase in serum levels of sELAM-1 (P<0.05) in comparison to control. However, only sICAM-1 levels were significantly increased in IgM cases more than in IgG cases. In amoebic liver abscess group, both sICAM-1 and sELAM-1 significantly increased when compared with control. In giardiasis group, highly significant increase of serum levels of sELAM-1 was noticed than in control group (P<0.01), while sICAM-1 showed no significant difference (P>0.05). There was no correlation between sELAM-1 and number of cysts in the stool (intensity of infection). Soluble forms of adhesion molecules especially sICAM-1 have the potentiality as good markers of endothelial damage, severity of disease and to less extend load of infection.

The present report is a case control study aimed to determine the levels of cytokines and other parameters in the sera of allergy-complicated and uncomplicated giardiasic children before and after metronidazole treatment. The study included a total of 126 subjects; 52 giardiasic children, 34 allergy-complicated giardiasis (36.9%) and 34 healthy controls, as well as six cases of giardiasis simultaneously infected with other parasites or bacterial pathogens. Serum levels of tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-1beta, soluble IL-2 receptor (sIL-2R), IL-6, IL-8, nitric oxide (NO), and C-reactive protein (CRP) were determined. TNF-alpha and sIL-2R levels significantly increased in giardiasic cases. IL-1beta, IL-6, IL-8, CRP, and NO levels increased only in the cases associated with allergy. All increased variables significantly decreased following metronidazole treatment and returned to normal levels. Metronidazole-treated patients became 100% parasite free. In conclusion, increased TNF-alpha and sIL-2R may be involved in pathogenesis of non-allergic giardiasis and probably Th1 type immune response seems to be predominant and this response may be protective rather than causative of the disease. Activation of the immune system takes place in giardiasis. It is broader and more intense in allergy-complicated giardiasis than that of uncomplicated cases, most probably due to non-invasive character of G. lamblia. Enhanced IgE production pointed to Th2-type immune response and confirms its association with allergy.

Chronic diarrhea is defined as a predominantly loose stool lasting longer than four weeks. A patient history and physical examination with a complete blood count, C-reactive protein, anti-tissue transglutaminase immunoglobulin A (IgA), total IgA, and a basic metabolic panel are useful to evaluate for pathologies such as celiac disease or inflammatory bowel disease. More targeted testing should be based on the differential diagnosis. When the differential diagnosis is broad, stool studies should be used to categorize diarrhea as watery, fatty, or inflammatory. Some disorders can cause more than one type of diarrhea. Watery diarrhea includes secretory, osmotic, and functional types. Functional disorders such as irritable bowel syndrome and functional diarrhea are common causes of chronic diarrhea. Secretory diarrhea can be caused by bile acid malabsorption, microscopic colitis, endocrine disorders, and some postsurgical states. Osmotic diarrhea can present with carbohydrate malabsorption syndromes and laxative abuse. Fatty diarrhea can be caused by malabsorption or maldigestion and includes disorders such as celiac disease, giardiasis, and pancreatic exocrine insufficiency. Inflammatory diarrhea warrants further evaluation and can be caused by disorders such as inflammatory bowel disease, Clostridioides difficile, colitis, and colorectal cancer.
