Point-of-care capillary blood lactate measurements in human immunodeficiency virus-uninfected children with in utero exposure to human immunodeficiency virus and antiretroviral medications.

ABSTRACT: To estimate the prevalence of elevated point-of-care (POC) capillary blood lactate concentrations in human immunodeficiency virus (HIV)-exposed, uninfected children (HEU) and to determine if POC lactate varies with in utero antiretroviral (ARV) exposure.The Surveillance Monitoring for Antiretroviral Therapy Toxicities protocol of the Pediatric HIV/AIDS Cohort Study enrolled 1934 children between 2007 and 2009, 0 to 12 years of age, born to HIV-infected mothers. POC lactate was measured annually on capillary blood using the Lactate Pro device. Associations of POC lactate with in utero ARV exposure and other characteristics were evaluated using logistic regression models, adjusting for maternal characteristics and other confounders.Of 1641 children with POC measurements (median age, 3.0 years), 3.4% had POC lactate >3 mmol/L. Median POC lactate level decreased with age (1.9 mmol/L, 1.7 mmol/L, and 1.6 mmol/L for children 0-<6 months [99% ?6 weeks of life], 6-<24 months, and ?24 months of age, respectively; P < 0.001). Prevalence of elevated POC lactate did not differ by in utero ARV exposure drug class, but was significantly higher in children exposed in utero to emtricitabine or efavirenz, cocaine or opiates, and those of white race.POC lactate testing is a useful rapid laboratory screening assay for HEU children with ARV exposure. ARV use during pregnancy has resulted in a dramatic decrease in mother-to-child transmission of HIV, and the risk of elevated lactate in HEU children is low. However, as new ARVs and more complex regimens are used during pregnancy by HIV-infected women, continued monitoring for infant toxicities is essential.

Project description:Most studies examining the association of prenatal antiretroviral (ARV) exposures with congenital anomalies (CAs) in children born to human immunodeficiency virus (HIV)-infected women have been reassuring, but some evidence suggests an increased risk with specific ARV agents.To evaluate the association of in utero ARV exposures with CAs in HIV-exposed uninfected children.Prospective cohort study design. The Pediatric HIV/AIDS Cohort Study's Surveillance Monitoring of ART Toxicities (SMARTT) Study was performed at 22 US medical centers among 2580 HIV-exposed uninfected children enrolled in the SMARTT Study between March 23, 2007, and June 18, 2012.First-trimester exposure to any ARV and to specific ARV medications.The primary end point was a CA based on physician review of infant physical examinations according to the Antiretroviral Pregnancy Registry modification of the Metropolitan Atlanta Congenital Defects Program. Rates of CAs were estimated overall and by birth year. Logistic regression models were used to evaluate the association of CAs with first-trimester ARV exposures, adjusting for demographic and maternal characteristics.Congenital anomalies occurred in 175 of 2580 children, yielding a prevalence of 6.78% (95% CI, 5.85%-7.82%); 242 major CAs were confirmed, including 72 musculoskeletal and 55 cardiovascular CAs. The prevalence of CAs increased significantly among successive birth cohorts (3.8% for children born before 2002 and up to 8.3% for those born 2008-2010). In adjusted models, no association of first-trimester exposures with CAs was found for any ARV, for combination ARV regimens, or for any drug class. No individual ARV in the reverse transcriptase inhibitor drug classes was associated with an increased risk of CAs. Among protease inhibitors, higher odds of CAs were observed for atazanavir sulfate (adjusted odds ratio [aOR], 1.95; 95% CI, 1.24-3.05) and for ritonavir used as a booster (aOR, 1.56; 95% CI, 1.11-2.20). With first-trimester atazanavir exposure, risks were highest for skin (aOR, 5.23) and musculoskeletal (aOR, 2.55) CAs.Few individual ARVs and no drug classes were associated with an increased risk of CAs in HIV-exposed infants after adjustment for calendar year and maternal characteristics. While the overall risk remained low, a relative increase was observed in successive years and with atazanavir exposure. Given the low absolute CA risk, the benefits of recommended ARV therapy use during pregnancy still outweigh such risks, although further studies are warranted.

Project description:Human immunodeficiency virus (HIV)-infected (HIV+) patients on combination antiretroviral therapy are living longer but have increased risk for aging-associated disease which may lead to increasing critical care requirements. We compare medical ICU admission characteristics and outcomes among HIV infected and demographically similar uninfected patients (uninfected) and considered whether an index which combines routine clinical biomarkers (the Veterans Aging Cohort Study Index) predicts 30-day medical ICU mortality.Observational data analyses (Veterans Aging Cohort Study).Eight Veterans Affairs medical centers nationwide.HIV infected and uninfected with a medical ICU admission between 2002 and 2010.None.Medical ICU admission was determined using bedsection (Veterans Affairs) and revenue center codes (Medicare). For Veterans Affairs admissions, we used clinical data to calculate Veterans Aging Cohort Study Index scores and multivariable logistic regression to determine factors associated with 30-day mortality. Overall, 539 of 3,620 (15%) HIV infected and 375 of 3,639 (10%) uninfected had a medical ICU admission; 72% and 78%, respectively, were Veterans Affairs based. HIV+ patients were younger at admission (p < 0.0001). Although most HIV+ patients were on antiretroviral therapy (71%) with undetectable HIV-1 RNA (54%), compared with uninfected they were more commonly admitted with respiratory diagnoses or infections (21% vs. 12%), were more likely to require mechanical ventilation (17% vs. 9%; p = 0.001), and had a higher mortality rate (18.6% vs. 11.2%, p = 0.003). Cardiovascular diagnoses were less common among HIV infected (18% vs. 29%; p < 0.0001). In logistic regression (c-statistic 0.87), a 5-point increment in Veterans Aging Cohort Study Index was associated with an odds ratio of death of 1.22 (95% confidence interval 1.14-1.30) among HIV infected and of 1.50 (95% confidence interval 1.29-1.76) among uninfected; infection/sepsis and respiratory diagnoses were also associated with mortality.Medical ICU admission was frequent, 30-day mortality higher, and mechanical ventilation more common in HIV infected compared with uninfected. The Veterans Aging Cohort Study Index calculated at medical ICU admission predicted 30-day mortality for HIV infected and uninfected. As more individuals age with HIV, their requirements for medical ICU care may be greater than demographically similar uninfected individuals.
