Celiac disease in osteoporotic Indians.

OBJECTIVE: 1) The aim of the study was to identify the atypical celiac disease (CD) in a cohort of symptomatic osteoporotic patients, younger than 55 years of age and 2) To study associated clinical and laboratory features and outcome with gluten-free diet. MATERIAL AND METHODS: We studied 33 patients (F:M = 28:5), mean age 29 years (range 15-52 years) with osteoporosis (WHO diagnostic criteria, T-score less than -2.5 on DEXA scan) from January 2000 - June 2002. Serological screening for CD was done by detecting circulating IgA antibodies to tissue transglutaminase by ELISA. Patients with presence of antibodies to transglutaminase were subjected to biopsy from the 2nd part of the duodenum by upper GI endoscopy. The biopsies were reported independently by two pathologists who were blinded for the serology report. Measurement of mucosal thickness, crypts and villi were done with an ocular micrometer. Other parameters like complete hemogram, serum iron, total iron binding capacity (TIBC), calcium profile, 25-OH-D, parathyroid hormone (PTH) were evaluated. Assessment of clinical and laboratory parameters was performed within 4-12 weeks of starting gluten-free diet (GFD). RESULTS: Thirteen patients had circulating IgA antibodies to transglutaminase. Intestinal biopsies were performed on 11 patients and were consistent with the diagnosis of CD (total villous atrophy--two, subtotal villous atrophy with crypt hyperplasia--nine). Patients with CD had significant anaemia when compared with non-CD osteoporotic patients. Other important observations in these 11 patients were low serum calcium and phosphorus, low 25-OH-D, high PTH. Significant improvement in clinical and laboratory parameters was noted in all patients within 6-12 weeks of starting GFD. CONCLUSION: Symptomatic osteoporotic patients (younger than 55 years of age) especially with associated anaemia should be investigated for CD. Simple measures like omission of wheat from diet (GFD) lead to significant improvement in symptoms within weeks.

Colonic tuberculosis: colonoscopic appearance and clinico-pathologic analysis.

BACKGROUND: There has been a resurgence of interest in intestinal tuberculosis because of acquired immunodeficiency syndrome (AIDS) epidemic sweeping our country. Role of colonoscopy and colonoscopy directed histology for diagnosing the disease have been emphasised since last few years. AIMS AND OBJECTIVES: To know the colonoscopic features in patients with intestinal tuberculosis and to study the clinicopathological findings in the same. METHODS: We studied twenty-one patients with intestinal tuberculosis referred to us between 1993-1997. Colonoscopy was done in all patients and biopsy specimens were collected from the site of lesion during the procedure. RESULTS: Ileocaecal disease was found in 9 patients, ileocaecal with contiguous ascending colon involvement in eight and segmental colonic tuberculosis in four cases. The colonoscopic findings included nodules in seven patients, nodules with ulcerations in three, ulcerations alone in seven, nodules with strictures in three and polypoidal mass in one patient. Eight cases revealed granuloma on histopathology. CONCLUSIONS: Though bacteriological and histological assessment of tissue is essential to differentiate tuberculosis from other disorders, we stress the importance of colonoscopic appearances in diagnosing tuberculosis. We also recommend antituberculous chemotherapy in patients with high clinical suspicion of tuberculosis on the basis of colonoscopic appearance alone after ruling other causes on histopathological examination.

Collision tumour of stomach.

Collision tumour of the stomach is exceedingly rare, with only four previous reported instances in which adenocarcinoma of the stomach was found in association with a single carcinoid tumour. Our case with adenocarcinoma had multiple carcinoid tumours in the stomach.
