Sexually transmitted infections among HIV-infected heavy drinkers in St Petersburg, Russia.

The objective of this study was to estimate the prevalence and identify correlates of four sexually transmitted infections (STIs) among HIV-infected Russians reporting heavy alcohol use and recent unprotected sex, we conducted a cross-sectional analysis of baseline data from the HERMITAGE study. The primary outcome was any current STI, based on urine tests for Neisseria gonorrhoeae, Chlamydia trachomatis and Trichomonas vaginalis and serological testing for infection with Treponema pallidum. Data on potential demographic and behavioural predictors of STI were obtained from surveys administered at study entry. Of 682 participants, 12.8% (95% confidence interval [CI] 10.3, 15.3) tested positive for at least one STI. In a multivariable model adjusted for gender, age and marital status, only sex trade involvement over the last three months was significantly associated with an increased odds of STI (adjusted odds ratio [AOR] 2.00, 95% CI 1.13, 3.55). Given that STIs were common in this HIV-infected cohort, and that few patient characteristics predicted STI, the current practice of screening HIV-infected Russians for syphilis alone merits re-evaluation.

Quantification of HIV-1-specific T-cell responses at the mucosal cervicovaginal surface.

OBJECTIVE: To characterize HIV-1 specific cellular immune responses at mucosal surfaces using a rapid, sensitive enzyme-linked immuno-spot (ELISPOT) technique. DESIGN: Cervicovaginal mononuclear cells obtained from cytobrush and cervicovaginal lavage were assessed for production of interferon-gamma (IFN-gamma) in response to stimulation by HIV-1 antigens. HIV-1 specific responses were compared in a cross-sectional study of two HIV-1-positive patient groups: women not currently on antiretroviral therapy with peripheral CD4 cell counts > 250 x 10(6)/l (n = 12); and women on highly active antiretroviral therapy (HAART) (n = 9). METHODS: Mononuclear cells from peripheral blood or cervicovaginal specimens were assessed in an ELISPOT assay for responses to HIV-1 antigens expressed by recombinant vaccinia viruses. This assay detects primarily CD8 T cells and shows good correlation with MHC class I tetramer staining of cytotoxic T lymphocytes. RESULTS: HIV-1 specific IFN-gamma spot-forming cells were detected in cervicovaginal samples of one out of nine women (11%) on HAART and five out of 12 women (42%) not currently on HAART. In peripheral blood mononuclear cells, HIV-1 specific IFN-gamma spot-forming cells were significantly more numerous in women not currently on HAART than in women on HAART (P = 0.009). In most cases, antigens recognized by mucosal T cells were also recognized by PBMC; however, there were exceptions. CONCLUSIONS: HIV-1-specific antigen-reactive T cells may be detected in routine, noninvasive gynecological specimens. The results suggest that cervicovaginal HIV-1-specific T cells may be less numerous in individuals on HAART than in those not on HAART, as shown previously for HIV-1-specific cytotoxic T lymphocytes in the peripheral blood.

The effect of continuous quality improvement on compliance with clinical practice guidelines in an optometric clinic: a retrospective review.

BACKGROUND: Quantitative documentation of quality is becoming increasingly more important. The SUNY State College of Optometry established clinical protocols outlining clinical standards for patient care. We compared documentation of actual clinical performance to these standards. METHODS: The Primary Care Service's Quality Management Team retrospectively reviews a random 10% sample of charts of patients seen in the teaching clinic of the SUNY State College of Optometry on an ongoing basis. They compare the care documented in the medical record to internally distributed clinical protocols. We reviewed the resultant data from January 1995 through June 1997 by analyzing the number of indicators that were out of compliance for each month. Then we graphed these data to ascertain trends and variability to determine what effect this continuous quality improvement process had on clinical care as measured by compliance with clinical protocols. RESULTS: A least-squares regression analysis demonstrated a correlation (0.717) between the decreasing number of items out of compliance and the time during which feedback was provided (r2 = 0.5143, p = 0.0001). These data show a distinct downward trend, indicating better compliance with the clinical protocols over time. We also found that the variability of the data decreased during the time period studied. CONCLUSIONS: A properly designed continuous quality improvement program that gives appropriate feedback to faculty optometrists and student interns measurably increased their compliance with--and decreased their variability from--this clinic's internally distributed clinical protocols over a 30-month time period.
