Profile of Chronic Comorbid Conditions and Obstetrical Complications Among Pregnant Women With Human Immunodeficiency Virus and Receiving Antiretroviral Therapy in the United States.

BACKGROUND: To evaluate the frequency and associated characteristics of chronic comorbid conditions and obstetrical complications among pregnant women with human immunodeficiency virus (HIV) and receiving antiretroviral therapy (ART) in comparison to those without HIV. METHODS: We compared 2 independent concurrent US pregnancy cohorts: (1) with HIV (International Maternal Pediatric Adolescent AIDS Clinical Trials Protocol P1025, 2002-2013) and (2) without HIV (Consortium for Safe Labor Study, 2002-2007). Outcomes were ≥2 chronic comorbid conditions and obstetrical complications. For women with HIV, we assessed whether late prenatal care (≥14 weeks), starting ART in an earlier era (2002-2008), and a detectable viral load at delivery (≥400 copies/mL) were associated with study outcomes. RESULTS: We assessed 2868 deliveries (n = 2574 women) with HIV and receiving ART and 211 910 deliveries (n = 193 170 women) without HIV. Women with HIV were more likely to have ≥2 chronic comorbid conditions versus those without HIV (10 vs 3%; adjusted OR [AOR]: 2.96; 95% CI: 2.58-3.41). Women with HIV were slightly less likely to have obstetrical complications versus those without HIV (both 17%; AOR: .84; 95% CI: .75-.94), but secondarily, higher odds of preterm birth <37 weeks. Late entry to prenatal care and starting ART in an earlier era were associated with a lower likelihood of ≥2 chronic comorbidities and obstetrical complications; detectable viral load at delivery was associated with a higher likelihood of obstetric complications. CONCLUSIONS: Pregnant women with HIV receiving ART have more chronic comorbid conditions, but not necessarily obstetrical complications, than their peers without HIV.

Myocardial Steatosis Among Antiretroviral Therapy-Treated People With Human Immunodeficiency Virus Participating in the REPRIEVE Trial.

BACKGROUND: People with human immunodeficiency virus (PWH) face increased risks for heart failure and adverse heart failure outcomes. Myocardial steatosis predisposes to diastolic dysfunction, a heart failure precursor. We aimed to characterize myocardial steatosis and associated potential risk factors among a subset of the Randomized Trial to Prevent Vascular Events in HIV (REPRIEVE) participants. METHODS: Eighty-two PWH without known heart failure successfully underwent cardiovascular magnetic resonance spectroscopy, yielding data on intramyocardial triglyceride (IMTG) content (a continuous marker for myocardial steatosis extent). Logistic regression models were applied to investigate associations between select clinical characteristics and odds of increased or markedly increased IMTG content. RESULTS: Median (Q1, Q3) IMTG content was 0.59% (0.28%, 1.15%). IMTG content was increased (> 0.5%) among 52% and markedly increased (> 1.5%) among 22% of participants. Parameters associated with increased IMTG content included age (P = .013), body mass index (BMI) ≥ 25 kg/m2 (P = .055), history of intravenous drug use (IVDU) (P = .033), and nadir CD4 count < 350 cells/mm³ (P = .055). Age and BMI ≥ 25 kg/m2 were additionally associated with increased odds of markedly increased IMTG content (P = .049 and P = .046, respectively). CONCLUSIONS: A substantial proportion of antiretroviral therapy-treated PWH exhibited myocardial steatosis. Age, BMI ≥ 25 kg/m2, low nadir CD4 count, and history of IVDU emerged as possible risk factors for myocardial steatosis in this group. CLINICAL TRIALS REGISTRATION: NCT02344290; NCT03238755.

Pre-diagnosis body mass index, physical activity and ovarian cancer mortality.

BACKGROUND: Ovarian cancer is the deadliest gynecologic malignancy, yet the effects on survival of modifiable pre-diagnosis lifestyle factors, such as obesity and physical activity, remain largely unexplored. Our objective was to evaluate the effect of pre-diagnosis BMI and physical activity on ovarian cancer mortality using prospectively collected data. METHODS: Data on women who developed ovarian cancer after enrollment into the NIH-AARP Diet and Health Study were analyzed. Cancer incidence was ascertained through linkage state cancer registries and consisted of 741 cases of epithelial ovarian cancer. RESULTS: Higher pre-diagnosis BMI was associated with increased overall and ovarian cancer-specific mortality. Comparing women with BMI 25-29.9, 30-34.9 and ≥ 35 to normal weight women, the HRs of overall mortality were 1.18 (95%CI 0.96-1.45), 1.05 (0.82-1.36) and 1.59 (1.14-2.18, p-trend = 0.02). The findings were similar for ovarian cancer-specific mortality comparing women with BMI ≥ 35 to normal weight women (BMI <25) with a HR of 1.47 (95%CI 1.03-2.09, p-trend 0.08). Pre-diagnosis physical activity was not associated with mortality, with HRs for overall mortality of 1.06 (95%CI 0.79-1.43), 0.94 (0.72-1.23), 0.98 (0.76-1.25), and 0.98 (0.75-1.28, p-trend = 0.91), comparing women who engaged in vigorous physical activity 1-3 times/month, 1-2 times/week, 3-4 times/week and 5 times/week, respectively, with those who never/rarely engaged in such activity. CONCLUSIONS: Women who were obese before developing ovarian cancer had increased mortality than those who were normal weight, but physical activity before diagnosis was not associated with mortality in this study population. These results suggest that maintaining a healthy weight is a powerful preventative tool.

Changing Patterns and Factors Associated With Mode of Delivery Among Pregnant Women With Human Immunodeficiency Virus Infection in the United States.

OBJECTIVE: To describe patterns and factors associated with mode of delivery among pregnant women with human immunodeficiency virus (HIV) infection in the United States in relation to evolving HIV-in-pregnancy guidelines. METHODS: We conducted an analysis of two observational studies, Pediatric AIDS Clinical Trials Group and International Maternal Pediatric Adolescent AIDS Clinical Trials Network Protocol P1025, which enrolled pregnant women with HIV infection from 1998 to 2013 at more than 60 U.S. acquired immunodeficiency syndrome clinical research sites. Multivariable analyses of factors associated with an HIV-indicated cesarean delivery (ie, for prevention of mother-to-child transmission) compared with other indications were conducted and compared according to prespecified time periods of evolving HIV-in-pregnancy guidelines: 1998-1999, 2000-2008, and 2009-2013. RESULTS: Among 6,444 pregnant women with HIV infection, 21% delivered in 1998-1999, 58% in 2000-2008, and 21% in 2009-2013; 3,025 (47%) delivered by cesarean. Cesarean delivery increased from 30% in 1998 to 48% in 2013. Of all cesarean deliveries, repeat cesarean deliveries increased from 16% in 1998 to 42% in 2013; HIV-indicated cesarean deliveries peaked at 48% in 2004 and then dropped to 12% by 2013. In multivariable analyses, an HIV diagnosis during pregnancy, initiation of antiretroviral therapy in the third trimester, a plasma viral load 500 copies/mL or greater, and delivery between 37 and 40 weeks of gestation increased the likelihood of an HIV-indicated cesarean delivery. In analyses by time period, an HIV diagnosis during pregnancy, initiation of antiretroviral therapy in the third trimester, and a plasma viral load of 500 copies/mL or greater were progressively more likely to be associated with an HIV-indicated cesarean delivery over time. CONCLUSION: Almost 50% of pregnant women with HIV infection underwent cesarean delivery. Over time, the rate of repeat cesarean deliveries increased, whereas the rate of HIV-indicated cesarean deliveries decreased; cesarean deliveries were more likely to be performed in women at high risk of mother-to-child transmission. These findings reinforce the need for both early diagnosis and treatment of HIV infection in pregnancy and the option of vaginal delivery after cesarean among pregnant women with HIV infection.

Inflammatory biomarker score and cancer: A population-based prospective cohort study.

BACKGROUND: Inflammation is associated with cancer but there are conflicting reports on associations of biomarkers of inflammation with cancer risk and mortality. We investigated the associations of C-reactive protein (CRP) and leukocyte count with cancer risk and mortality using individual biomarkers, and an inflammatory score derived from both biomarkers. METHODS: We conducted this analysis among 2,570 men enrolled in the population-based, prospective Kuopio Ischemic Heart Disease Risk Factor Study in Finland. During an average follow-up period of 26 years, 653 cancer cases and 287 cancer deaths occurred. We computed a z-score for each participant, with the combined z-score being the sum of each individual's CRP and leukocyte z-scores. Multivariable-adjusted Cox proportional hazard model was used to evaluate associations with cancer risk and mortality. RESULTS: Using individual biomarkers, elevated leukocyte count was associated with an increased risk of cancer (RR = 1.31, 95% CI 1.04-1.66), and cancer mortality (RR=, 95% CI 1.39, 0.98-1.97). The corresponding results for CRP were (RR = 1.23, 95% CI 0.97-1.55) for risk and (RR = 1.15, 95% CI 0.81-1.64) for cancer mortality. Associations of the biomarkers with cancer appeared to be more robust using the combined z-score. HRs comparing men within the highest z-score quartile to those within the lowest z-score quartiles were 1.47 (95% CI 1.16-1.88, p-trend < 0.01) for cancer risk, and 1.48 (95% CI 1.03-2.14, p-trend = 0.09) for cancer mortality. CONCLUSION: Our study suggests that inflammation is associated with cancer risk and mortality, and combining inflammatory biomarkers into a score is a robust method of elucidating this association.
