“…Available data suggest a high degree of completeness for the CDC AIDS surveillance in the study region during the years of this study. A national study reported a completeness of 92% for 1988, 14 and internal analyses by the Maryland AIDS Registry reported a completeness of 94% for 1991 (personal communication). These evaluations of the reporting rate relied on hospitalization records.…”

Background and Purpose-Although acquired immunodeficiency syndrome (AIDS) is thought to increase the risk of stroke, few data exist to quantify this risk. This is the first population-based study to quantify the AIDS-associated risk of stroke. Methods-We identified all incident ischemic stroke (IS) and intracerebral hemorrhage (ICH) cases among young adults 15 to 44 years of age in central Maryland and Washington, DC, who were discharged from any of the 46 hospitals in the study area in 1988 and 1991. Using data from the medical records, 2 neurologists reviewed each case to confirm the diagnosis. Cases of AIDS among these patients with stroke were defined using Centers for Disease Control and Prevention criteria (1987).

We used complementary approaches to estimate the cumulative incidence of infection with the human immunodeficiency virus (HIV) among persons with haemophilia in the United States of America. One approach, ratio estimation, divided the cumulative number of haemophiliacs diagnosed with acquired immunodeficiency syndrome (AIDS) in the United States by the corresponding cumulative proportion with AIDS among HIV-positive subjects in the Multicenter Hemophilia Cohort Study (MHCS). The other approach, back-calculation, reconstructed past HIV incidence from national surveillance of AIDS using essentially non-parametric estimates of the hazard functions for AIDS and for pre-AIDS death. We derived confidence intervals that fully incorporated uncertainty about the hazard functions. Results from the two approaches were consistent. Around 9200 haemophiliacs became infected during the course of the epidemic. Of them, around 7000 were living with HIV or AIDS as of 31 December 1992 and at least 5630 as of 31 December 1995. Credible calculations for this group must account for those who die before AIDS and for the significantly longer incubation times in those infected as children or adolescents. The consistency of back-calculation and cohort data in haemophiliacs supports the use of back-calculation to estimate prevalence in other populations.

Municipal drinking water and cryptosporidiosis among persons with AIDS in Los Angeles County

et al. 1994

SUMMARYTo assess unfiltered drinking water as a source of cryptosporidium infection in patients with the acquired immunodeficiency syndrome (AIDS) the prevalence of cryptosporidiosis among persons with AIDS in Los Angeles County was assessed by water service area. One water distributor, serving approximately 60 % of the county's residents (area B), has consistently employed filtration. The other company, which serves the remainder of the county (area A), did not institute filtration until mid-December 1986. This difference provided a 'natural experiment' in which to assess the effect of municipal water filtration on the level of cryptosporidiosis among persons with AIDS. The prevalence of cryptosporidiosis among AIDS patients was compared for the two water service areas for the time period preceding the implementation of filtration in area A. From 1983 to 1986 the age-standardized prevalence of cryptosporidiosis among AIDS patients was 32 % lower in area A (4-2 %), which received unfiltered water, than in area B (6-2 %). Following addition of filtration in area A, the prevalence of cryptosporidiosis among AIDS patients decreased by 20 %; however, a decline, of 47 %, was also observed in area B. The similar baseline levels of cryptosporidiosis and the corresponding post-filtration decline in both areas suggest that filtration had no effect on levels of cryptosporidiosis among persons with AIDS. Thus it does not appear that municipal drinking water is an important risk factor for cryptosporidiosis in AIDS patients residing in Los Angeles County.
