Relation of stavudine discontinuation to anthropometric changes among HIV-infected women.

OBJECTIVE: To characterize changes in regional anthropometry associated with stavudine exposure and discontinuation. DESIGN: Seven hundred thirty-four HIV-infected participants who reported using stavudine (574 of whom later discontinued stavudine) and 698 HIV-uninfected participants from the Women's Interagency HIV Study provided anthropometrics at 8706 semiannual visits between July 1999 and March 2005. METHODS: Changes in weight, waist, chest, upper arm, hip, and midthigh circumferences were evaluated using linear regression with generalized estimating equations. RESULTS: HIV-uninfected women demonstrated increases in regional anthropometry at every body site, whereas HIV-infected women demonstrated decreases in weight and circumferences of the waist, chest, hip, and thigh. A smaller annual decrease in hip circumference was seen after discontinuing stavudine for >2.25 years compared with the decrease observed while on stavudine (P = 0.01). Discontinuing stavudine for >2.25 years was associated with smaller (P < 0.05) decreases in hip (-0.06 cm/y) and thigh (-0.005 cm/y) circumference compared with the decreases observed between 1 and 2.25 years (hip: -0.46 cm/y, thigh: -0.24 cm/y) or < or =1 year (hip: -0.64 cm/y, thigh: -0.27 cm/y) after stavudine discontinuation. CONCLUSIONS: Regardless of continuing or discontinuing stavudine, HIV-infected women demonstrate decreases in weight and body circumference measurements over time. The lower limb seems to be most affected by stavudine exposure, with stabilization observed more than 2 years after discontinuation.

Incidence of lipoatrophy and lipohypertrophy in the women's interagency HIV study.

OBJECTIVE: To estimate the incidence of lipoatrophy and lipohypertrophy among HIV-infected and HIV-uninfected women from the Women's Interagency HIV Study. DESIGN: Eight hundred fifteen women with semiannual data on self-report of bidirectional change in body fat, anthropometric measurements, weight, and bioelectric impedance analysis were included in a 30-month incidence analysis. METHODS: Lipoatrophy and lipohypertrophy in both peripheral (arms, legs, and buttocks) and central (waist, chest, and upper back) sites were defined by self-report of either a decrease or an increase in a body fat region over the previous 6 months that was confirmed by a corresponding change in anthropometric measurement. RESULTS: Weight and total body fat increased in HIV-uninfected women but remained stable in HIV-infected women over 30 months. Among HIV-infected women, the incidence of peripheral (relative hazard, 2.1; 95% confidence interval [CI], 1.4-3.3) and central (relative hazard, 1.9; 95% CI, 1.2-2.8) lipoatrophy was about double that among HIV-uninfected women, after adjustment for age and race. The incidence of peripheral lipohypertrophy appeared lower among HIV-infected women than among HIV-uninfected women (relative hazard, 0.8; 95% CI, 0.6-1.1), while the incidence of central lipohypertrophy did not differ by HIV status. Of HIV-infected women with 2 of 4 lipodystrophy outcomes, most (81%) had combined peripheral and central lipoatrophy or combined peripheral and central lipohypertrophy. Only 14% of these women had both peripheral lipoatrophy and central lipohypertrophy. CONCLUSIONS: These prospective data suggest that lipoatrophy, affecting both peripheral and central sites, predominates in HIV-infected women. The simultaneous occurrence of peripheral lipoatrophy and central lipohypertrophy was uncommon.

Protease inhibitor use and the incidence of diabetes mellitus in a large cohort of HIV-infected women.

OBJECTIVE: To assess the association between protease inhibitor (PI) use and the incidence of diabetes mellitus (DM) among participants in the Women's Interagency HIV Study. DESIGN: Prospective multicenter cohort study. The diagnosis of DM was based on self-report at semiannual interviews conducted from 1994 to 1998. SETTING: Six inner-city clinical sites in the United States (Brooklyn, NY; Bronx, NY; Washington, DC; Chicago, IL; San Francisco, CA; and Los Angeles, CA). PARTICIPANTS: A total of 1785 nonpregnant women who had no history of prior DM. The women made up four groups: 1) PI users (n = 609, person-years [PY] at risk = 707); 2) reverse transcriptase inhibitor (RTI)-only users (n = 932, PY = 1486); 3) HIV-infected women reporting no antiretroviral therapy (ART) ever (n = 816, PY = 1480); and 4) HIV-uninfected women (n = 350, PY = 905). MAIN OUTCOMES: Incidence of DM and median body mass index (BMI) from 1995 to 1998 were compared among the four groups. RESULTS: Sixty-nine incident cases of DM occurred among 1785 women (1.5 cases per 100 PY; 95% CI: 1.2-1.9). The incidence of DM among PI users was 2.8 cases per 100 PY (2.8%) versus 1.2% among both RTI users and women on no ART (95% CI: 1.6-4.1 [PI]; 0.7-1.8 [RTI and no ART]; P = 0.01 for comparison of the PI group with the RTI group) and 1.4% among HIV-uninfected women (95% CI: 0.7-2.2, P = 0.06 for comparison with PI group). Weight gain was not associated with either PI or RTI use. Multivariate models identified PI use (hazard ratio [HR] = 2.90 [95% CI: 1.50-5.60]; P = 0.002), age (HR = 1.75 per 10 years [95% CI: 1.31-2.34]; P = 0.0002) and BMI as independent risk factors for DM. CONCLUSIONS: PI use was associated with a threefold increase in the risk of reporting incident DM. Routine screening for diabetes, particularly among older and heavier patients using PI therapy, is advisable.

Tuberculosis in the elderly.

As the result of the strengthening of TB-control programs nationwide, a decline in the overall number of reported TB cases in the United States has been observed within the last 10 years. Despite these declines in absolute numbers, the elderly continue to account for a disproportionate share of the cases. The high number of cases diagnosed at autopsy among the elderly suggests that this condition often remains unrecognized, possibly due to the subtle clinical manifestations in this age group. Evidence suggests that, compared with their community-dwelling counterparts, the institutionalized elderly are at a greater risk for re-activation of latent TB and for the acquisition of new TB infection. More studies are needed to make final conclusions. New guidelines for the treatment of LTBI emphasize targeted TST among persons at high risk for development of active TB and no longer use age as an exclusionary condition. All nursing home residents must therefore be regularly screened for LTBI and treated if necessary. Even though elderly persons are at greater risk for hepatic toxicity from TB treatment, the poor outcome of untreated TB in this age group warrants more aggressive treatment of this condition.
