RESUMO

Severe mpox has been observed in people with advanced human immunodeficiency virus (HIV). We describe clinical outcomes of 13 patients with advanced HIV (CD4 <200 cells/µL), severe mpox, and multiorgan involvement. Despite extended tecovirimat courses and additional agents, including vaccinia immune globulin, cidofovir, and brincidofovir, this group experienced prolonged hospitalizations and high mortality.

RESUMO

Few studies have examined the vitamin D status in HIV-infected patients. A cross-sectional retrospective chart review of 2992 HIV-infected patients was conducted from 9/2008 to 5/2009. A total of 274 adult patients had 25-hydroxyvitamin D [25(OH)D] obtained by radioimmunoassay. None was receiving vitamin D (vitD) supplements. Vitamin D status was defined as the following: vitD deficiency (vitDd) as 25(OH)D <25 nmol/liter, vitD insufficiency (vitDi) as 25(OH)D 25-74 nmol/liter, and vitD optimal (vitDo) as 25(OH)D ≥75 nmol/liter. We analyzed demographic/laboratory data. vitDd, vitDi, and vitDo were 21.2% (58 patients, 58/274), 68.6% (188 patients, 188/274), and 10.2% (28 patients, 28/274), respectively. There were significant racial differences. Blacks were 60.3% (35 patients, 35/58), 40.4% (76 patients, 76/188), and 28.6 % (8 patients, 8/28) in vitDd, vitDi, and vitDo, respectively, p=0.002. CD4 T cell count was not different in these three groups. However, HIV viral load was significantly different. Median log (10) HIV viral load was 2.31 with IQR 1.70-409, 1.70 with IQR 1.70-2.96, and 1.70 with IQR 1.70-2.78 in vitDd, vitDi, and vitDo, respectively, p=0.039. Multivariate logistic regression analysis showed that black race [odd ratio (OR) 4.108, 95% confidence interval (CI) 1.462-11.543, p=0.007] and HIV viral load>50 copies/ml (OR 2.396, 95% CI 1.120-5.127, p=0.024) were significantly associated with vitamin D deficiency. Vitamin D deficiency was highly prevalent in HIV-infected patients. Detectable HIV viremia and dark skin (black ethnicity) were significantly associated with vitamin D deficiency. Evaluation of vitamin D status in HIV-infected patients should be considered and further studies are needed to define the effects of vitamin D.

RESUMO

BACKGROUND: Patients with human immunodeficiency virus (HIV) infection are at increased risk of accelerated coronary artery disease (CAD) and cardiovascular events. Stress echocardiography (SE) is routinely used for risk stratification and prognosis of patients with known or suspected CAD. The prognostic value of SE in this high-risk group is unknown. The purpose of this study was to evaluate the prognostic value of SE in HIV-infected patients with known or suspected CAD. METHODS AND RESULTS: We evaluated 311 patients (age, 52 ± 9 years; 74% men; left ventricular ejection fraction, 54 ± 12%) with history of HIV, undergoing SE (56% dobutamine). Left ventricular wall motion was evaluated on a 16-segment model, 5-point scale. An abnormal SE was defined by a fixed (infarction), biphasic, or new (ischemia) wall motion abnormality on stress. Follow-up for cardiac death and myocardial infarction was obtained. Seventy-nine (26%) patients had an abnormal SE. After 2.9 ± 1.9 years, 17 confirmed myocardial infarction and 14 cardiac deaths occurred. SE risk-stratified patients into normal versus abnormal subgroups (event rate, 0.6% per year versus 11.8% per year; P < 0.0001). Both abnormal SE (hazard ratio, 28.2; 95% confidence interval, 6.2 to 128.0; P < 0.0001) and the presence of any ischemia on SE (hazard ratio, 3.4; 95% confidence interval, 1.3 to 8.6; P = 0.009) were independent predictors of cardiac events. On a forward conditional Cox proportional hazards regression model, SE provided incremental prognostic value over clinical, stress ECG, and resting echocardiographic variables (global χ(2) increased from 17.8 to 24.5 to 65 to 109, P < 0.05 across all groups). CONCLUSIONS: SE can effectively risk-stratify and prognosticate patients with HIV. The presence of ischemia and scar during SE provides independent and incremental prognostic value over traditional variables. A normal SE response portends a benign prognosis even in this high-risk subset.
