IV ceftriaxone therapy results in short-term cognitive improvement for patients with posttreatment Lyme encephalopathy, but relapse in cognition occurs after the antibiotic is discontinued. Treatment strategies that result in sustained cognitive improvement are needed.
The resurgence of tuberculosis in New York City has been largely attributed to the acquired immune deficiency syndrome (AIDS) epidemic. However, historical events predating the advent of AIDS and worsening economic and social conditions, including a rise in homelessness, have contributed significantly to the increase. We prospectively studied 224 consecutive patients with tuberculosis admitted to a large public hospital in New York over the first 9 months of 1988. Initial assessment included medical status, human immunodeficiency virus (HIV) risk factors, and detailed social information, including substance abuse history and housing status. All patients were tracked after discharge to determine compliance and cure rates. Tuberculosis patients were predominantly male (79%), with high rates of alcohol use (53%), intravenous drug and/or "crack" cocaine use (64%), and homelessness or unstable housing (68%). Half the patients had AIDS or AIDS-related complex (ARC) or were HIV antibody positive. A total of 178 patients were discharged on tuberculosis treatment, but 89% of these were lost to follow-up and failed to complete therapy. Of the 178 discharged patients, 48(27%) were readmitted within 12 months with confirmed active tuberculosis. Of these patients, 40 were discharged on treatment and at least 35 were again lost to follow-up. In a multivariate regression model noncompliance was significantly associated with the absence of AIDS or ARC (p less than 0.001), homelessness (p less than 0.005), and alcoholism (p less than 0.05). Because HIV infection and tuberculosis converge in a subpopulation with high rates of substance abuse and homelessness, the problem of ensuring treatment compliance may grow considerably in the future.(ABSTRACT TRUNCATED AT 250 WORDS)
The lower BMD, higher prevalence of low BMD, and higher levels of bone turnover markers detected in HIV+ postmenopausal minority women could place them at high risk for future fractures.
The objective of this cross-sectional study was to estimate the prevalence of and risk factors for osteoporosis in HIV+ postmenopausal women. Bone mineral density (BMD) by dual energy X-ray absorptiometry (DXA) and biochemical indices of mineral metabolism were measured in 31 Hispanic and African American HIV+ postmenopausal women. BMD was compared with 186 historical controls, matched for age, ethnicity and postmenopausal status. Mean BMD was significantly lower at the lumbar spine and total hip in the HIV+ group, as compared with controls. Prevalence of osteoporosis was higher in the HIV+ group than controls at the lumbar spine (42% vs 23%, p=0.03) and total hip (10% vs 1%, p=0.003). Among HIV+ women, time since menopause and weight were significant predictors of BMD, while duration or class of
Bacterial sepsis, a major complication of chronic hemodialysis, is due mainly to infections of the vascular access site despite increasing use of internal fistulas. Sixty episodes of septicemia occurred in two chronic dialysis centers, with an incidence of 0.15 episodes of significant bacteremia per patient-dialysis-year in each. Forty-four of the 60 episodes were judged to be due to vascular access site infection by clinical, bacteriologic, and histologic criteria. Seventy percent (31 of 44) of the vascular access site-related episodes were due to staphylococci and 25% (11 of 44) to Gram-negative bacilli; nonvascular access site-related episodes were often due to transplant site infections caused by Gram-negative bacilli or streptococci. Mortality was about 18% in both vascular access site-related and nonrelated septic episodes. Bovine heterograft arteriovenous fistulas more often led to sepsis than did Brescia arteriovenous fistulas. Treatment with appropriate antibiotics was successful in most cases. Routine removal or ligation of the vascular access site was not necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
