The objective of this study was to determine factors associated with prescription of highly active antiretroviral therapy (HAART). The authors observed 9530 patients eligible for antiretroviral therapy (ART) in more than 100 hospitals and clinics in 10 US cities. Multiple logistic regression analysis was used to assess factors associated with HAART prescription, stratifying patients by no history versus history of ART to assess the association between prescription and CD4, viral load, and outpatient visits. Overall, female gender (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.60-0.76) and alcoholism (OR, 0.85; 95% CI, 0.74-0.99) were associated with decreased likelihood of HAART prescription. Enrollment at a private facility (OR, 1.33; 95% CI, 1.14-1.56), heterosexual exposure (OR, 1.34; 95% CI, 1.13-1.58), and Hispanic ethnicity (OR, 1.19; 95% CI, 1.04-1.37) were associated with prescription. For patients with no history of prescribed ART, CD4 <500 cells/microL (OR, 3.94; 95% CI, 2.02-7.66), and high viral load were associated with increased likelihood of prescription; for patients with history of ART prescription, those whose outpatient visits averaged > or =2 per 6-month interval (OR, 1.30; 95% CI, 1.10-1.54) were more likely and those with high viral load were less likely to be prescribed HAART (OR, 0.50; 95% CI, 0.44-0.56). The authors found differences in HAART prescription by gender, race, exposure mode, alcoholism, and provider type for all patients, by CD4 and viral load for patients with no history of ART prescription, and by average number of outpatient visits and viral load for patients with history of ART prescription.
To study the relation of occupational exposures and pancreatic cancer, we evaluated data from males (198 cases and 209 controls) participating in a hospital-based case-control study conducted in a high-risk area of Louisiana between 1979 and 1983. The questionnaire obtained information on lifetime occupational history, as well as dietary, smoking, and drinking habits and demographic characteristics. After adjustment for smoking and dietary patterns, white collar occupations showed consistent elevations in risk, whereas associations for other occupations were in general unremarkable. Although not significantly elevated, risks for truck drivers (OR = 1.7) and those with long-term employment in machine repair or as mechanics were suggestive (OR = 2.5). No association was found for jobs in oil refining or oil and gas extraction (ORs were 0.5 and 0.4, respectively), although risks were slightly elevated for long-term workers in the chemical processing industry (OR = 1.2). While these associations deserve further study, our findings are consistent with results of other studies which do not suggest that occupational exposures are important determinants of pancreatic cancer.
Treatment of tuberculosis (TB) in persons coinfected with HIV has become increasingly complex during the past decade. We describe the factors that complicate anti-TB therapy in a large observational cohort of HIV-infected persons in the United States. Among 367 HIV-infected patients with 372 episodes of culture-confirmed TB, 44.1% had injection drug use as a mode of HIV transmission. Hepatic disease was present at the time of TB diagnosis or during anti-TB therapy for 91 episodes (24.5%). Elevation at least twice the upper limits of normal of aminotransaminases was observed during the first month of anti-TB therapy in 116 (31.2%) of the episodes. The most commonly reported adverse effects occurring during therapy were rash (27.8%), nausea (26.2%), leukopenia or neutropenia (20.2%), diarrhea (19.3%), vomiting (18.5%), and elevated temperature (>101.5 degrees F [38.6 degrees C], 16.9%). Prescription of a rifamycin and a medication known to interact with rifamycins occurred during 270 (72.6%) episodes. Because HIV-infected patients with TB often have underlying complicating conditions, such as hepatic disease, and are treated with medications that may have toxicities and cause drug-drug interactions, we recommend that clinicians pay careful attention to these factors when treating coinfected patients.
The purpose of this study was to describe the clinical profile of end-stage acquired immune deficiency syndrome (AIDS) since the advent of highly active antiretroviral therapy (HAART). A cross-sectional examination of human immunodeficiency virus (HIV)-infected patients who attended a public HIV outpatient clinic and died between 1996 and 2001 was conducted (n = 669). All clinical and demographic data were collected from the Centers for Disease Control (CDC) Adult Spectrum of Disease database. The prevalence of first-time acquisition of AIDS-defining conditions 12 months before death were evaluated. The prevalence of renal disease, hepatic disease and substance use were also evaluated. The majority of the patients were 35 years old or older, male, African American and HAART-experienced. The six AIDS-defining conditions with the highest percentages of first-time acquisition in the last 12 months of life were HIV dementia (91.8%), progressive multifocal leukoencephalopathy (PML) (91.7%), wasting (90.9%), Mycobacterium avium complex infection (MAC) (80.0%), lymphoma (78.6%), and cytomegalovirus infection (CMV) (78.1%). Forty-four percent of the patients were diagnosed with at least one of these six conditions 12 months before death. More than one third of the patients had renal or hepatic failure, injecting drug use (IDU) as the HIV risk factor, and history of substance use. AIDS-defining conditions continue to have an impact on mortality, especially the neurologic conditions and wasting. However, other conditions, such as renal and hepatic disease, are becoming important causes of mortality because the HIV-infected population now includes more drug users, and HIV-infected patients are surviving for longer periods. These results should help clinicians better time the discussion of end-stage options and improve the patient's quality of life.
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.
