Gastroesophageal reflux disease and its association with bronchiolitis obliterans syndrome in allogeneic hematopoietic stem cell transplant recipients.

OBJECTIVES: Bronchiolitis obliterans syndrome is a significant postallogeneic hematopoietic stem cell transplant problem. Recent data in lung transplant patients suggest an association with gastroesophageal reflux disease and bronchiolitis obliterans syndrome. We studied posthematopoietic stem cell transplant patients with bronchiolitis obliterans syndrome for gastroesophageal reflux disease and its response to a proton pump inhibitor. MATERIALS AND METHODS: Seven postallogeneic hematopoietic stem cell transplant patients with bronchiolitis obliterans syndrome were studied. Gastroesophageal reflux disease was assessed by 24-hour pH monitoring with a Bravo catheter-free radio pH capsule. Patients with positive gastroesophageal reflux disease were started on omeprazole. Pretreatment and posttreatment pulmonary function tests were done at 3-month intervals. RESULTS: Of 7 patients, 5 had positive results for gastroesophageal reflux disease (71%). Omeprazole had a disease-stabilizing effect on the patients' pulmonary function tests. CONCLUSIONS: Our study shows a significant association between bronchiolitis obliterans syndrome and gastroesophageal reflux disease in postallogeneic hematopoietic stem cell transplant patients. Use of omeprazole may have a disease-stabilizing effect in short-term follow-up.

Inflammatory bowel disease in Saudi Arabia: a hospital-based clinical study of 312 patients.

BACKGROUND AND OBJECTIVES: The epidemiology, clinical characteristics, and natural course of inflammatory bowel disease (IBD) in Saudi Arabia are still largely unknown. Hence, we decided to conduct a large retrospective, cohort study to determine these features of the disease. DESIGN AND SETTING: Retrospective study conducted in a tertiary care hospital in Riyadh from January 1970 to December 2008. PATIENTS AND METHODS: We reviewed all the cases of IBD diagnosed and collected all data pertaining to patients with IBD. RESULTS: A total of 312 patients with IBD were included for this analysis, including 197 (63%) patients with Crohn disease (CD) and 115 (37%) patients with ulcerative colitis (UC). The mean age (standard deviation) of patients with IBD was 25.5 (10.6) years; 152 (48.7%) were males and 160 females. The referral rate in the past 10 years was 72.1% compared with preceding 20 years, and 56% (n=178) of patients with IBD were from the central region of Saudi Arabia. The patients were followed up for a mean duration of 9.5 years; during their follow-up, 206 patients (66%) required hospital admission and 9 patients (2.9%) with UC developed colon cancer. A total of 6 patients died during the follow-up. Fifty-three percent (n=104) of the patients with CD underwent surgeries as part of their treatment, whereas only 20% (n=23) of the patients with UC underwent colectomy. CONCLUSIONS: The incidence of IBD has been gradually increasing in Saudi Arabia over the years. Clinical features and morbidity in patients are not different from patients with IBD seen in the West.

Bio-enteric intragastric balloon in obese patients: a retrospective analysis of King Faisal Specialist Hospital experience.

BACKGROUND: Bio-enteric intragastric balloon (BIB) insertion is gaining popularity for weight reduction in obese patients. We evaluated the efficacy, tolerability, and safety of BIB in the treatment of obesity. METHODS: A total of 173 Saudi obese patients [mean+/-SD age 34.5 +/- 11.6 years, 58 (33.5%) were men] who underwent BIB (InaMed Corporation, California, USA) insertion were followed up clinically, biochemically, and endoscopically for 6-12 months. The mean+/-SD baseline body weight, excess weight, and body mass index (BMI) were 123.5 +/- 39.6 and 68.9 +/- 40.0 kg and 46.7 +/- 14.1 kg/m(2), respectively. Associated dietary control, exercise, and medical treatment were used in 67 (38.7%), 60 (34.7%), and 3 (1.7%), respectively. RESULTS: BIBs were safely and successfully inserted in 15.1 +/- 6.2 min, filled with 626.2 +/- 41.7 ml methylene blue solution, removed after a period of 189.7 +/- 68.3 days, within 14.1 +/- 6.3 min. BIB was not tolerated for 6 months in 33 (19.8%) patients. Body weight and BMI at 6 and 12 months postinsertion were significantly reduced to 112.5 +/- 35.7 kg and 43.1 +/- 13.1 kg/m(2), and 110.7 +/- 34.5 kg and 42.3 +/- 12.6 kg/m(2), respectively (p < 0.01 versus baseline by one-way ANOVA). Furthermore, the mean absolute weight loss and mean percentage excess weight reduction (EWR) at 6 and 12 months post-BIB insertion were 13.5 +/- 13.5 kg and 19.5 +/- 21.8, and 14 +/- 18.5 kg and 18.0 +/- 25.8, respectively. No mortality or major complications has occurred. EWR of >or=25% occurred in 24.1% and 30.1% of patients at 6 and 12 months postinsertion, respectively. CONCLUSION: BIB is a safe, simple, and potentially efficient procedure that is well-tolerated by the majority of patients.
