Invasive Hemodynamics and Rejection Rates in Patients With Cardiac Sarcoidosis After Heart Transplantation.

BACKGROUND: Orthotopic heart transplant (OHT) is increasingly used for end-stage heart failure due to cardiac sarcoidosis (CS). However, concern regarding long-term outcomes in patients with CS after OHT persists because of multiorgan involvement. METHODS: Baseline demographics and invasive hemodynamics were measured in 12 patients with CS and 28 patients with nonischemic cardiomyopathy requiring OHT at the time of transplantation, 1 week after OHT, and in routine follow-up. Primary endpoints included changes in pulmonary artery pressure, right ventricular stroke work index, and pulmonary compliance. Secondary endpoints included degree of allograft rejection and death. RESULTS: During a mean follow-up of 73.8 months, no differences in pulmonary artery pressures, right ventricular stroke work index, or cardiac index were observed in patient with CS (n = 12) compared with those without CS (n = 28) between 1 week after OHT and the most recent follow-up. Long-term follow-up showed that pulmonary hemodynamics remained normal in the CS group. International Society for Heart and Lung Transplantation (ISHLT) 1990 grade ≥ 1a rejection occurred less frequently in the CS group (17% vs 68%, P = 0.006), and 0 of 12 patients in the CS group experienced histologic or clinical recurrence of sarcoidosis or ≥2 rejection. Patients with CS had excellent survival after OHT, with 0 deaths or significant rejection. CONCLUSIONS: Patients with CS have similar post-transplant hemodynamics as patients without CS, without evidence of right ventricular dysfunction or pulmonary hypertension. Neither significant rejection nor recurrence of sarcoid in the allograft was observed in this cohort of patients with CS. Survival is similar between patients with CS and those without CS. Heart transplant is a viable strategy in selected patients with CS with excellent outcomes.

Delivery of health care for cardiovascular and metabolic diseases among people living with HIV/AIDS in African countries: a systematic review protocol.

BACKGROUND: People living with HIV (PLHIV) in African countries are living longer due to the rollout of antiretroviral drug therapy programs, but they are at increasing risk of non-communicable diseases (NCDs). However, there remain many gaps in detecting and treating NCDs in African health systems, and little is known about how NCDs are being managed among PLHIV. Developing integrated chronic care models that effectively prevent and treat NCDs among PLHIV requires an understanding of the current patterns of care delivery and the major barriers and facilitators to health care. We present a systematic review protocol to synthesize studies of healthcare delivery for an important subset of NCDs, cardiovascular and metabolic diseases (CMDs), among African PLHIV. METHODS/DESIGN: We plan to search electronic databases and reference lists of relevant studies published in African settings from January 2003 to the present. Studies will be considered if they address one or both of our major objectives and focus on health care for one or more of six interrelated CMDs (ischemic heart disease, stroke, heart failure, hypertension, diabetes, and hyperlipidemia) in PLHIV. Our first objective will be to estimate proportions of CMD patients along the "cascade of care"-i.e., screened, diagnosed, aware of the diagnosis, initiated on treatment, adherent to treatment, and with controlled disease. Our second objective will be to identify unique barriers and facilitators to health care faced by PLHIV in African countries. For studies deemed eligible for inclusion, we will assess study quality and risk of bias using previously published criteria. We will extract study data using standardized instruments. We will meta-analyze quantitative data at each level of the cascade of care for each CMD (first objective). We will use meta-synthesis techniques to understand and integrate qualitative data on health-related behaviors (second objective). DISCUSSION: CMDs and other NCDs are becoming major health concerns for African PLHIV. The results of our review will inform the development of research into chronic care models that integrate care for HIV/AIDS and CMDs among PLHIV. Our findings will be highly relevant to health policymakers, administrators, and practitioners in African settings. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42015029375.

An effective intervention to reduce intravaginal practices among HIV-1 uninfected Kenyan women.

Intravaginal practices (IVP) are common among African women and are associated with HIV acquisition. A behavioral intervention to reduce IVP is a potential new HIV risk-reduction strategy. Fifty-eight HIV-1-uninfected Kenyan women reporting IVP and 42 women who denied IVP were followed for 3 months. Women using IVP attended a skill-building, theory-based group intervention occurring weekly for 3 weeks to encourage IVP cessation. Vaginal swabs at each visit were used to detect yeast, to detect bacterial vaginosis, and to characterize the vaginal microbiota. Intravaginal insertion of soapy water (59%) and lemon juice (45%) was most common among 58 IVP women. The group-counseling intervention led to a decrease in IVP from 95% (54/58) at baseline to 0% (0/39) at month 3 (p=0.001). After 3 months of cessation, there was a reduction in yeast on vaginal wet preparation (22% to 7%, p=0.011). Women in the IVP group were more likely to have a Lactobacillus iners-dominated vaginal microbiota at baseline compared to controls [odds ratio (OR), 6.4, p=0.006] without significant change in the microbiota after IVP cessation. The group counseling intervention was effective in reducing IVP for 3 months. Reducing IVP may be important in itself, as well as to support effective use of vaginal microbicides, to prevent HIV acquisition.
