| 1 | Mutifactorial analysis of risk factors for reduced bone mineral density in patients with Crohn’s disease显示文摘AIM: To determine the prevalence of osteoporosis in a cohort of patients with Crohn’s disease (CD) and to identify the relative significance of risk factors for osteoporosis. METHODS: Two hundred and fifty-eight unselected patients (92 M, 166 F) with CD were studied. Bone mineral density (BMD) was measured at the lumbar spine and hip by dual X-ray absorptiometry. Bone formation was assessed by measuring bone specific alkaline phosphatase (BSAP) and bone resorption by measuring urinary excretion of deoxypyridinoline (DPD) and N-telopeptide (NTX). RESULTS: Between 11.6%-13.6% patients were osteoporotic (T score < -2.5) at the lumbar spine and/or hip. NTX levels were significantly higher in the patients with osteoporosis (P < 0.05) but BSAP and DPD levels were not significantly different. Independent risk factors for osteoporosis at either the lumbar spine or hip were a low body mass index (P < 0.001), increasing corticosteroid use (P < 0.005), and male sex (P < 0.01). These factors combined accounted for 23% and 37% of the reduction in BMD at the lumbar spine and hip respectively. CONCLUSION: Our results confirm that osteoporosis is common in patients with CD and suggest that increased bone resorption is the mechanism responsible for thebone loss. However, less than half of the reduction in BMD can be attributed to risk factors such as corticosteroid use and low BMI and therefore remains unexplained. | Sarah A Bartram Robert T Peaston David J Rawlings David Walshaw Roger M Francis Nick P Thompson | 2006 | World Journal of Gastroenterology2006，12，35： | 2 |
| 2 | Fatal gastrointestinal histoplasmosis 15 years after orthotopic liver transplantation显示文摘We report a case of ileo-colonic Histoplasmosis without apparent respiratory involvement in a patient who had previously undergone an orthotopic liver transplant(OLT) for primary biliary cholangitis 15 years earlier. The recipient lived in the United Kingdom,a non-endemic region for Histoplasmosis. However,she had previously lived in rural southern Africa prior to her OLT. The patient presented with iron deficiency anaemia,diarrhoea,abdominal pain and progressive weight loss. She reported no previous foreign travel,however,it later became known that following her OLT she had been on holiday to rural southern Africa. On investigation,a mild granulomatous colitis primarily affecting the right colon was identified,that initially improved with mesalazine. Her symptoms worsened after 18 mo with progressive ulceration of her distal small bowel and right colon. Mycobacterial,Yersinia,cytomegalovirus and human immunodeficiency virus infections were excluded and the patient was treated with prednisolone for a working diagnosis of Crohn's disease. Despite some early symptom improvement following steroids,there was subsequent deterioration with the patient developing gram-negative sepsis and multi-organ failure,leading to her death. Post-mortem examination revealed that her ileo-colonic inflammation was caused by Histoplasmosis. | Nikita Agrawal David EJ Jones Jessica K Dyson Tim Hoare Sharon A Melmore Stephanie Needham Nick P Thompson | 2017 | World Journal of Gastroenterology2017，23，43： | 1 |
