Helicobacter Pylori Infection And Micronutrient Deficiencies., Javed Yakoob, Wasim Jafri, Shahab Abid

Section of Gastroenterology

It is known that deficiencies of micronutrients due to infections increase morbidity and mortality. This phenomenon depicts itself conspicuously in developing countries. Deficiencies of iron, vitamins A, E, C, B12, etc are widely prevalent among populations living in the third world countries. Helicobacter pylori (H pylori) infection has a high prevalence throughout the world. Deficiencies of several micronutrients due to H pylori infection may be concomitantly present and vary from subtle sub-clinical states to severe clinical disorders. These essential trace elements/micronutrients are involved in host defense mechanisms, maintaining epithelial cell integrity, glycoprotein synthesis, transport mechanisms, myocardial contractility, brain development, cholesterol …

Candida Esophagitis: Risk Factors In Non-Hiv Population In Pakistan, Javed Yakoob, Wasim Jafri, Shahab Abid, Nadim Jafri, Muhammad Islam, Saeed Hamid, Hasnain Ali Shah, Akbar S. Hussainy

Section of Gastroenterology

AIM:

Candida esophagitis is a frequent infection in immunocompromised patients. This study was designed to determine its characteristics in non- human immune deficiency virus (HIV) infected patients attending a teaching hospital.

METHODS:

Clinical records of all patients coded by international classification of diseases 9th revision with clinical modifications' (ICD-9-CM), with candida esophagitis diagnosed by esophagogastroduodenoscopy (EGD) and histopathology over a period of 5 years were studied.

RESULTS:

Fifty-one patients (27 males, 24 females, range 21-77 years old and mean age 52.9 years) fulfilled the criteria (0.34% of the EGD). The common predisposing factors were carcinoma (OR 3.87, CI 1.00-14.99) and …

Section of Gastroenterology

Objective: To evaluate the symptomatology of irritable bowel syndrome (IBS) among health care professionals attending an IBS symposium in a tertiary care university hospital. Method: A questionnaire designed to incorporate Manning and Rome II criteria was distributed among participants of an IBS symposium, most of them were health care professionals. A total of 100 questionnaires were distributed, 41 had symptoms fulfilling criteria of IBS. In these patients male: female ratio was 28:13 with age range 18-68. Results: The predominant symptom was abdominal pain 87.8 % (36/41) which was aggravated post-prandially 72.2% (29/41), relieved following defecation in 87 % (35/41) with …

Ccr5 Mediates Specific Migration Of Toxoplasma Gondii—Primed Cd8+ Lymphocytes To Inflammatory Intestinal Epithelial Cells, Souphalone Luangsay, Lloyd H. Kasper, Nicolas Rachinel, Laurie A. Minns

Dartmouth Scholarship

Toxoplasma gondii, an obligate intracellular parasite, can invade intestinal epithelial cells and elicit a robust Th1 immune response. In this model of intestinal inflammation, CD8⁺ intraepithelial lymphocytes (IELs) secrete transforming growth factor (TGF)-β, which appears necessary for the maintenance of homeostasis in the intestine. However, the mechanism responsible for the IEL migration to the inflamed intestine is still unclear.An in vitro coculture cell system was used to quantify the IEL attraction by an infected intestinal epithelial cell line (m-IC_cl2). We used CCR5-deficient mice to determine which chemokine receptor—chemokine interaction could be responsible for the recruitment of …
