Dietary Total Antioxidant Capacity and Risk of Gall Stone: A Case-Control Study.

Background: Since the relation between dietary total antioxidant capacity (DTAC) and the occurrence of gallstone disease (GSD) remains unclear, we conducted, for the first time, a case-control study to clarify this association in the Iranian population. Methods: In the present case-control study, convenience Sampling was performed. A total of 600 participants (300 case and 300 control) were included. Anthropometric, demographic, physical activity, and nutrient intakes data were obtained from each subject. DTAC was calculated using the US Department of Agriculture's database. The odds ratio (OR) and 95% confidence intervals were assessed using unconditional logistic regression. Results: The participants in the highest quartile of DTAC had a significantly lower OR for gallstone than the lowest quartile, which remained significant after further adjustment for age, sex, and education (model 2: OR, 0.34; 95% CI, 0.16-0.71). In addition, after adjustment for age, sex, education, BMI, physical activity, and energy, the results revealed that participants with the highest quartile of DTAC had 71% lower odds of gallstone than those with the lowest quartile (model 3: OR, 0.29; 95% CI, 0.11-0.78). Conclusions: The results of the present study demonstrated that the DTAC had an inverse association with GSD incident. However, interventional approaches are needed to confirm the relation between DTAC and GSD prevention.

Kimura's disease with eosinophilic panniculitis--treated with cyclosporine: a case report.

Kimura's disease is a rare, benign, slow growing chronic inflammatory swelling with a predilection for the head and neck region and almost always with peripheral blood eosinophilia and elevated serum IgE levels. Here, we report a 25-year-old male patient with asthma, Reynaud phenomenon, eosinophilic panniculitis, bilateral inguinal lymphadenopathy and peripheral blood eosinophilia.He responded initially to oral prednisolone with the subsidence of peripheral blood eosinophilia, asthma and the Reynaud phenomenon. But with tapering of prednisolone symptoms reappeared and hereby he was treated with cyclosporine. He has been symptom free for 6 months of follow up while taking cyclosporine 25 mg orally per day. Eosinophilia has resolved. This case shows that in addition to previously reported associations, Kimura disease may be associated with eosinophilic panniculitis and that cyclosporine could be effective in its treatment.

Butachlor-induced acute toxic hepatitis.

Butachlor is a highly effective herbicidal substance widely used by farmers. We report a 60-year-old man with exfoliative dermatitis, jaundice, increase in liver enzymes and eosinophilia one day after accidental dermal exposure to butachlor toxin. The diagnostic workup showed no other cause and liver histology was consistent with substance-induced toxic hepatitis. Within two weeks of conservative therapy, his liver function tests returned to normal.

Relationship between serum alanine aminotransferase levels and liver histology in chronic hepatitis C-infected patients.

BACKGROUND: The efficacy of serum alanine aminotransferase (ALT) levels in predicting the severity of hepatitis C virus (HCV) infection is unclear. OBJECTIVE: To compare histologic scoring of liver pathology in patients with chronic HCV infection with normal or elevated serum ALT. METHODS: Liver biopsies were performed in patients with HCV infection and either normal (n=40) or elevated (n=76) serum ALT levels, and scored for activity and fibrosis using the modified histological activity index. RESULTS: Patients with normal ALT and elevated ALT had similar demographic features. Median (range) histological activity grade was higher in patients with elevated ALT than in those with normal ALT (6 [1-15] vs. 5 [0-11], respectively; p=0.001), as was the fibrosis stage (2 [0-6] vs. 1[0-6]; p=0.02). Two patients with normal ALT and 4 with elevated ALT had liver cirrhosis. CONCLUSIONS: Among patients with chronic HCV infection, liver lesions are milder in those with normal serum ALT levels than those with abnormal ALT levels. However, some patients with normal ALT too may have advanced liver disease.

Idiopathic hypereosinophilic syndrome presenting with liver mass: Report of two cases: Idiopathic hypereosinophilic syndrome and liver mass.

Herein, we report on two cases of hypereosinophilic syndrome presenting as liver mass. One patient was a 22-year-old woman presented with fever, upper abdominal pain, nausea/vomiting and a mass in the right liver lobe. The second patient was a 54-year-old man who presented with nausea and abdominal pain with significant weight loss. He had multiple lesions in both liver lobes. Both patients had eosinophilia that was not attributed to other causes such as allergy or parasites. The patients were treated with glucocorticosteroid and improved clinically. Imaging and laboratory abnormalities resolved.

Pattern of relapses in Iranian patients with ulcerative colitis. A prospective study.

BACKGROUND: The pattern of relapses in patients with ulcerative colitis (UC) has a significant role in taking decisions about the therapy and the follow up of patients. This study is designed to find out the pattern, time and severity of relapses in Iranian patients with UC. METHOD: From 1991 to 2003, a period of 13 years, the pattern of relapses in 163 patients with UC who had been admitted to a private referral gastroenterology clinic in Iran were evaluated. RESULTS: 163 patients (58.3% female, 41.7% male) were included, aged from 17 to 74 years with mean age of 38.9 ± 12.3 years. Mean follow up time was 52.7 ± 41.4 months (ranges 12 and 155 months). Mean relapse chance was 0.028 ± 0.036 for each patient in every month (ranges 0-0.21). The mean time from the initial attack to the first relapse was 23.8 ± 22.5 months, which was not the same in patients with different primary disease severity (p = 0.03). CONCLUSION: The time and severity of the relapses relate to the severity of UC. Iranian patients have a milder course of the disease.

Bone mineral density in Iranian patients with inflammatory bowel disease.

Patients with inflammatory bowel disease (IBD) are at increased risk of developing osteopenia and osteoporosis. The aim of the study was to investigate the prevalence of decreased bone density and related risk factors in Iranian IBD patients. A total of 126 ulcerative colitis (UC) and 39 Crohn's disease (CD) patients were enrolled. Dual-energy x-ray absorptiometry technique was used to measure bone density, and blood samples were obtained to measure biochemical markers. To find predictive variables for bone mineral density (BMD), stepwise regression analysis was carried out. A total of 53 IBD patients (32.1%) had diminished bone mineral density at either lumbar spine (L1-L4) or femoral neck. Of these, 9 (5.4%) had osteoporosis; however, 44 (26.7%) were osteopenic. Femoral neck bone density was significantly decreased among CD patients (p<0.04). There was no significant difference in BMD between men and women. We have found significant differences in BMD T scores at lumbar L1-L4, L2-L4, and femoral neck in corticosteroid ever-users (p<0.002, p<0.001, p<0.003, respectively). There was no significant difference in biochemical markers between UC and CD patients, except that more CD patients were hypocalcemic (p<0.001). Stepwise regression analysis has revealed lumbar spine T score was predicted by age (p<0.0001), corticosteroid use (p<0.002), and body mass index (BMI) (p<0.005); however, femoral neck was predicted by age (p<0.0001), BMI (p<0.0001), smoking (p<0.009), and corticosteroid use (p<0.028). Low bone density in Iranian UC and CD patients is in accordance with Western societies. Treatment with corticosteroid has increased this possibility in both groups. Corticosteroid use, age, smoking, and BMI are predictive factors for low bone density.

Gastrointestinal complications in two patients with common variable immunodeficiency.

Common variable immunodeficiency (CVID) is a primary immunodeficiency disease characterized by hypogammaglobulinemia and recurrent bacterial infections especially in respiratory and gastrointestinal systems. We present here 2 cases of CVID with gastrointestinal complications.Case 1 is a 25-year-old man with a history of chronic diarrhoea from childhood. Ultrasonography revealed ascites, with liver size smaller than normal. Liver biopsy showed non-specific hepatitis. Lymphoid proliferation and Histiocytosis were reported in his ascites cytology. Moreover friability in colonoscopy due to moderate active chronic colitis was detected. Case 2 is a 26-year-old man with chronic diarrhoea since 8 years. Abdominal sonography revealed increased liver echogenicity, increased liver size, and some enlarged lymph nodes beside pancreas. Colonoscopy revealed friability and decreased vascularity while biopsy showed moderate active chronic colitis. Lymph node biopsy showed unusual immunologic reaction. Moreover, small bowel transition test showed nodularity. CVID should be considered in any patient with gastrointestinal manifestations especially chronic diarrhoea in association with recurrent bacterial infections in other organs. Diagnostic delay results in more morbidity and complications in untreated patients..
