Colonoscopy Findings in HIV-Infected Men and Women from an Urban U.S. Cohort Compared with Non-HIV-Infected Men and Women.

INTRODUCTION: As HIV-infected patients live longer, non-AIDS-defining cancers are now a major cause of morbidity and mortality. The purpose of this study was to compare the prevalence, type, and location of colorectal neoplastic lesions found on colonoscopy in HIV-infected patients from an urban U.S. cohort with non-HIV-infected patients. METHODS: We collected clinical data and colonoscopy findings on 263 HIV-infected patients matched with 657 non-HIV-infected patients on age, race, and sex. Frequency distributions and descriptive statistics were used to characterize the study population. The primary exposure was HIV infection, and the primary outcome was any adenoma or adenocarcinoma. Logistic regression models were used to estimate odds ratios with 95% confidence intervals (CIs). RESULTS: Participants were primarily African American and 40% were women. HIV-infected patients were less likely to have any neoplastic lesions (21.3% vs. 27.7%, p < .05), adenoma (20.5% vs. 27.1%, p = .04), tubular adenomas >10 mm (0.4% vs. 2.9%, p = .02), and serrated adenomas (0.0% vs.2.6%, p = <.01). There was a nonsignificant increased prevalence of adenocarcinoma in HIV-infected individuals compared with non-HIV-infected individuals (1.5% vs. 0.8%, p = .29). The lower prevalence of any adenoma remained after controlling for age, sex, smoking status, body-mass index, and diabetes mellitus [adjusted odds ratio (aOR), 0.61; 95% CI, 0.43-0.88]. HIV-infected patients had a lower prevalence of colorectal neoplastic lesions, including high-risk adenomas, than non-HIV-infected patients. CONCLUSIONS: Our findings suggest that HIV infection in a primarily African American population is associated with a lower prevalence of colorectal adenomas, but not adenocarcinoma, found by colonoscopy.

Pregnancy outcomes in women with osteogenesis imperfecta.

OBJECTIVE: To assess the relationship between osteogenesis imperfecta (OI) type, mode of delivery and outcomes as self-reported by women in the International Osteogenesis Imperfecta (OI) Registry. METHODS: A cross-sectional study using data from 274 women with OI who reported their experience with pregnancy practices, including mode of delivery, number of children, genetic counseling, assisted conception techniques, mean ages at menarche and at menopause, and pregnancy complications. Chi-square analyses were performed to compare pregnancy outcomes, number of children and OI type. Prevalence ratios and 95% confidence intervals were obtained to quantify exposure-outcome relationships. RESULTS: The most common mode of delivery was the sole use of cesarean section (C-section) reported by 55% of the participants. Approximately two-thirds had at least two children. Twenty-nine percent (n = 80) reported pregnancy complications. There was a significant relationship between the mode of delivery and OI type (p < 0.001), genetic counseling (p = 0.010), and number of children (p < 0.0001). There was neither evidence of an association between pregnancy complications and number of children (p = 0.16), OI type (p = 0.27), nor mode of delivery (p = 0.11). CONCLUSIONS: These findings suggested that clinical OI type, pre-natal genetic counseling, and number of children were strong predictors for choosing the mode of delivery. Severity of OI, multiparity, and vaginal delivery were not associated with increased pregnancy complications in this cohort of women with OI.
