ABSTRACT
Summary: Eosinophilic esophagitis (EoE) is a chronic allergen/immune-mediated disease leading to esophageal dysfunction. Food allergens play critical roles in the pathogenesis and treatment of EoE via different mechanisms. This study aimed to present the characteristics and evaluate the ability of skin prick test (SPT), skin prick to prick test (SPP) (IgE-mediated), and atopic patch test (APT) (cell-mediated) individually or simultaneously to diagnose food allergy in patients suffering from EoE. This prospective study was conducted on 58 patients with EoE. Seven patients (12.1%) were positive to only one, 3 (5.2%) were simultaneously positive to two, and 32 (55.2%) were simultaneously positive to three tests. Single and double sensitizations were totally 10.4% in IgE-mediated reactions, while 36.5% in cell-mediated reactions. In contrast, poly sensitization (> 2 allergens) was 51.7% in IgE-mediated tests and 20.7% in the cell-mediated test. Multiple sensitization findings showed egg white, milk, yolk, and soy were the most frequent allergens. Our findings indicate that EoE is early onset and associated with multiple food sensitizations, particularly via IgE-mediated mechanisms. These immune-mediated responses encompass both IgE-mediated (SPT and SPP) and cell-mediated (APT) reactions simultaneously not individually. Therefore, employing multiple assays may strengthen the diagnosis of food sensitization.

Introduction. Intractable diarrhea of infancy (IDI) includes several types of early onset diarrhea; one of the rare etiologies is trichohepatoenteric (THE) syndrome, also known as syndromic diarrhea (SD) which was primarily described by Stankler et al. Hereby we report a family with several affected members which to our knowledge is the first case report from Iran. Report of Cases. A three-year-old boy referred with short stature, poor weight gain, and intermittent steatotic diarrhea to our center. He was born to healthy, relative parents (cousins). He did not gain any weight after four months of age and began having intermittent steatotic diarrhea, abdominal distension, and fever. He was hospitalized several times. Two other children in the family also showed somewhat similar symptoms. Two sweat tests were negative for cystic fibrosis. Workup for Celiac disease was performed several times which was negative; however, gluten-free diet was tried several times which was not effective. Workup for Hirschsprung's disease was performed but colon was ganglionic. Evidence of liver involvement was approved by elevated liver enzymes and coarse echo of liver on sonography. Discussion. Trichoenterohepatic syndrome should be put in mind in cases of intractable diarrhea presenting in a family with several affected members. Early diagnosis would save patients from unnecessary workups.

BACKGROUND: Obesity is associated with multiple comorbidities such us metabolic and cardiovascular diseases. AIMS: Evaluate metabolic profile and to determinate the frequency of metabolic syndrome in Tunisian obese adult. METHODS: It's a prospective study realized in the unit of obesity research in the national institute of nutrition between April 2003 and March 2005.This study concerned two groups of subjects aged between 20 and 60 years old : Group 1 (n = 100) obese (BMI (3) 30 kg/m2) and group 2 (n= 60) controls with normal weight (BMI between 18,5 and 24,9 kg/m2). RESULTS: Mean number of metabolic complications is significantly higher (P < 10-3) in obese (3,28 +/- 2) than in controls (1,16 +/- 1,2). Impaired fasting glucose and type 2 diabetes mellitus are respectively more frequent in obese (37 % and 16 %) than in non obese (5 % et 1,7 %). Hyperinsulinemia is significantly (P<10-3) more frequent in obese. hypertriglyceridemia, hypercholesterolemia and hyperapolipoproteinaemia B are significantly (P = 0,01, P < 10-3 et P < 10-3) more frequent in obese than in no overweight subjects. The prevalence of hyperuricemia increased significantly (P = 0,01) in overweight subjects than in normal weight subjects. Metabolic syndrome is significantly more frequent (P < 10-3) in obese (48 %) than in control (1,7 %). CONCLUSION: Obesity, especially visceral obesity , is associated with a cluster of metabolic complications increasing the risk of coronary heart disease. We stress on the importance of primary prevention and early management of obesity.
