Brief Report: The Amsterdam Symptom and Risk-Based Score Predicts for Acute HIV Infection in Men Who Have Sex With Men in San Diego.

ABSTRACT: OBJECTIVE:Dijkstra et al recently described a risk- and symptom-based score moderately predictive for HIV seroconversion in the preceding 6-12 months in men who have sex with men (MSM) in Amsterdam. Our objective was to determine whether this "Amsterdam Score" could also predict for acute HIV infection (AHI) in MSM. DESIGN AND SETTING:This study is a case-control analysis of a prospectively enrolled cohort of MSM who voluntarily presented for HIV testing in San Diego. The study sample was composed of MSM who screened HIV antibody-negative and then either tested positive with AHI [HIV nucleic acid test (NAT)-positive] or tested HIV NAT-negative. METHODS:The Amsterdam Score was calculated for each participant in the study sample. Score performance was assessed using receiver operating characteristic curves and their area under the curve (AUC). An optimal cutoff was determined using the Youden index. RESULTS:Seven hundred fifty-seven MSM (110 AHI and 647 HIV NAT-negative) were included in the analysis. AHI and HIV-negative cases were similar in age [median 32 years (interquartile range 26-42) vs 33 (27-45), respectively, P = 0.082]. The Amsterdam Score yielded a receiver operating characteristic curve with an AUC of 0.88 (95% confidence interval: 0.84 to 0.91). An optimal cutoff of ?1.6 was 78.2% sensitive and 81.0% specific. CONCLUSIONS:The risk- and symptom-based Amsterdam Score was highly predictive (AUC of 0.88) of AHI in MSM in San Diego. The Amsterdam Score could be used to target NAT utilization in resource-poor settings among MSM who test HIV antibody-negative, although the potential cost-savings must be balanced with the risk of missing AHI diagnoses.

Project description:Peripheral artery disease (PAD) affects millions of people, both in the U.S. and worldwide. Even when asymptomatic, PAD and the ankle-brachial index (ABI), the major clinical diagnostic criterion for PAD, are associated with decreased functional status and quality of life, as well as mobility impairment. Whether the ABI or change in the ABI predicts decline in functional status over time has not been previously assessed in a population-based setting.Participants were 812 non-Hispanic white, African American, Hispanic, and Asian men and women from the San Diego Population Study (SDPS) who attended a baseline examination (1994-1998), and follow-up clinic examination approximately 11 years later. The Medical Outcomes Study 36-Item Short Form (SF-36) was obtained at both the baseline and follow-up examinations, and the summary performance score (SPS) at the follow-up examination. Associations of the baseline ABI and clinically relevant change in the ABI (<-0.15 vs ?-0.15) with change in SF-36 scores over time were assessed using growth curve models, a type of mixed model that accounts for within participant correlation of measurements over time, and using linear regression for SPS. Models were adjusted for baseline age, sex, race/ethnicity, body mass index, ever smoking, physical activity, hypertension, diabetes, and dyslipidemia.Mean ± standard deviation (SD) for the baseline ABI was 1.11 ± 0.10, and 50.8 ± 9.0 for the baseline Physical Component Score (PCS), 50.1 ± 9.5 for the baseline Mental Component Score (MCS), and 11.2 ± 1.9 for the SPS at the follow-up examination. In fully adjusted models, each SD lower of the baseline ABI was significantly associated with an average decrease over time of 0.6 (95% confidence interval [CI], -1.1 to -0.1; P = .02) units on SF-36 PCS. Each SD lower of the baseline ABI was also significantly associated with an average decrease over time of 1.2 units (95% CI, -2.3 to -0.2; P = .02) on the SF-36 physical functioning subscale, and a decrease of 1.3 units (95% CI, -2.3 to -0.3; P = .01) on the SF-36 energy/vitality subscale in fully adjusted models. Baseline ABI was not significantly associated with change in the SF-36 MCS over time, or the SPS at the follow-up examination. Change in the ABI was not associated with SF-36 PCS, MCS, or the SPS.In this multiethnic population of healthy middle-aged community-living men and women, we showed that participants with a lower baseline ABI had declines in functional status over 11 years. Findings suggest that small differences in the ABI, even within the normal range, may identify subclinical lower extremity PAD, which in turn may help to identify individuals at risk for declining functional status with age.
