RETROVIRUS RESEARCH CENTER CLINICAL, SOCIODEMOGRAPHIC AND IMMUNOLOGICAL PROFILE: BEFORE, DURING AND AFTER THE IMPLEMENTATION OF HAART THERAPY. Universidad Central del Caribe School of Medicine, University Hospital Ramon Ruiz Arnau Bayamon, Puerto Rico
Rationale • Retrovirus Research Center has been collecting data prospectively since 1992 • Availability of HAART began shortly after 1995 • Data on socio-demographic, clinical and immunological variables are available for study.
Methods • Study Design: • A cross sectional study from a longitudinal cohort. • Setting: • The study group comes from the Bayamon area in the northern part of the island. Our health facilities serves eleven municipalities with a population of 660,440 inhabitants. • Study Group: • 3,151 HIV infected patients seen between 1992 through 2002.
Methods • Variables: • Period of entry: (1992-1995, 1996-1998, 1999-2002) • Sociodemographic: age, gender. • HIV transmission mode and risk behaviors: IDU, heterosexual, MHSM, others • Clinical presentation (Stage of infection, patterns of chronic diseases, and profile of OI, medical therapy) • Immunological variables( CD4, CD8, HIV viral load • Survival analysis (time between AIDS diagnosis and last event (death or not death).
Methods • Statistical Analyses: • Frequency, Percents, Mean, Median, SD, proportions, mortality rates. • Differences in proportions: Chi-Square, Fisher Exact test • Differences in mean: T-test for independent samples ANOVA. • Survival Analyses: Kaplan Meier procedure and Cox Model. • The overall significance level used was set to 0.05. • The statistical package used was SPSS 11.0 for Windows.
Patient Flow Chart TOTAL (at December 2002) MALE 76% 72% 66% FEMALE 24% 28% 34% P=.0001
Stage at Presentation Percent Years P=.0001
AGE OF PATIENTS AT STUDY ENTRY Percent Years p<.0001
Mean Age at Entry P<0.01
AGE AND ENTRY WITH CLINICAL AIDS Percent Years P=.0001
HIV RISK SCENARIO Percent P=.0001
AIDS DEFINING CONDITIONS AS PER YEAR Percent of Patients <1996 1996-98 >1998 *p<.01
PRESENCE OF CHRONIC CONDITIONS PERCENT OF PATIENTS <1996 1996-98 >1998 P<001
USE OF ANTIRETROVIRAL THERAPY PERCENT OF PATIENTS ART <1996 1996-98 >1998 P<001
Early MortalityMortality prior to last day of first interval Percent P<.0001
Survival analysis within the HIV patientsdescribe by years of entry, n=982. P<.0001
Survival analysis within the AIDS diagnosed patients describe by years of entry, n=2167. P< .0001
CONCLUSIONS • INCREASED • FEMALES • HETEROSEXUAL BEHAVIOR AS RISK • AGE (OLDER PATIENTS IN PARTICULAR >55Y) • PATIENTS WITH IMMUNOLOGICAL AIDS AT ENTRY • CHRONIC CONDITIONS (DM,CV) • USE OF HAART INTERVENTION • MEDIAN SURVIVAL IN HIV AND AIDS
CONCLUSIONS • DECREASED • IVU AS RISK FACTOR • CLINICAL AIDS AND HIV STAGE AT ENTRY • TOTAL CD4 CELL COUNT IN HIV AND AIDS • PCP, TOXO, TB AS INFECTIONS IN AIDS) • MORTALITY WITHIN SIX MONTHS OF ENTRY
