BackgroundProbiotics are used to provide health benefits. The present study tested the effect of a probiotic yoghurt on faecal output of beta-defensin and immunoglobulin A in a group of young healthy women eating a defined diet.Findings26 women aged 18-21 (median 19) years residing in a hostel were given 200 ml normal yoghurt every day for a week, followed by probiotic yoghurt containing Bifidobacterium lactis Bb12® (109 in 200 ml) for three weeks, followed again by normal yoghurt for four weeks. Stool samples were collected at 0, 4 and 8 weeks and assayed for immunoglobulin A and human beta-defensin-2 by ELISA. All participants tolerated both normal and probiotic yoghurt well. Human beta-defensin-2 levels in faeces were not altered during the course of the study. On the other hand, compared to the basal sample, faecal IgA increased during probiotic feeding (P = 0.0184) and returned to normal after cessation of probiotic yoghurt intake.ConclusionsBifidobacterium lactis Bb12® increased secretory IgA output in faeces. This property may explain the ability of probiotics to prevent gastrointestinal and lower respiratory tract infections.

Aims:The aim was to assess the dietary pattern during Ramadan season among type 2 diabetic Muslim subjects who underwent fasting and intensive dietary counseling.Materials and Methods:The study was conducted among 70 Muslim subjects with type 2 diabetes mellitus who undertook fasting during Ramadan and was part of a randomized control trial using pioglitazone published previously. All subjects were subjected to a dietary assessment and counseling at three stages, i.e., initiation of the study, mid-Ramadan and post-Ramadan, by a trained dietician. Dietary assessment was done by the 24-hour dietary recall method and the food frequency questionnaire. Diabetic diet sheets were dispensed to subjects based on their body mass index (BMI), daily activity, and needs.Results:The mean caloric intake between pre-Ramadan (before fasting) and mid-Ramadan (15 days after fasting) were 1506.80 kcal and 1614.29 (P = 0.001) respectively. The distribution of active components pre and during Ramadan were: carbohydrates (g) 260.76 and 265.35 g (P = 0.001), proteins (g) 43.64 and 46.19 (P = 0.001) and fat (g) was 32.88 and 44.16 (P = 0.0001) respectively. The percentage of energy from dietary carbohydrate prior to fasting (64.11 ± 6.73) and during fasting (68.41 ± 4.41) remained almost unchanged but statistically significant when compared at different intervals before and during fasting. Fat intake increased significantly during fasting (P = < 0.001).Conclusions:The dietary composition in a type 2 diabetic Muslim population who undertook fasting during Ramadan showed a mean increase in consumption of all components of diet during the period of fasting. Nutritional compliance during such a time seems to be difficult and warrants repeated counseling and regular follow-up to achieve targets.

Objective:To identify the differences in urinary profile of a stone former and the matched member of the family.Patients and Methods:This prospective case-control study was conducted from April 2006 to January 2008. Forty-one matched pairs from one geographic region were recruited. Renal/ureteric idiopathic calcium nephrolithiasis in patients of 18 years and above were included as cases. Controls were of the same gender and first-degree relative with no urolithiasis or history. They were living together at least for the last 5 years and consuming minimum of two out of three major meals together per day. For cases and controls besides fluid intake, ambulatory serum analysis for calcium, phosphorus, uric acid, albumin-globulin ratio, sodium, potassium and bicarbonate was done. Ambulatory 24-hour urinalysis was done for urinary volume, calcium, phosphorus, oxalate, uric acid, citrate, magnesium, creatinine and urinary pH was measured. For controls X-ray and USG-Kidney-Ureter-Bladder was done to rule out stone disease. The statistical analysis was done using Mc-Nemar test.Results:Of the 41, 31 cases (76%) were first-time stone formers. No statistical difference was found for 24-hour urinary calcium (P = 0.68), oxalate (P = 0.68), citrate (P = 0.45) and urinary volume (P = 0.14). All pairs had normal 24-hour urinary magnesium, uric acid and urinary pH.Conclusions:The urinary biochemical profile of idiopathic calcium nephrolithiasis was similar to the appropriately matched family member. It appears that an independent intrinsic factor may possibly be present and responsible for stone disease. The usefulness of urinary metabolic evaluation is seems to be of doubtful significance.
