RESUMO

Chronic immune activation and ensuing inflammation that accompany HIV infection lead to adverse metabolic consequences and an increased risk of type 2 diabetes (T2D). We examined the additive effects of T2D on circulating biomarkers involved in inflammation, coagulation, and vascular function along with plasma amino acids in people living with HIV (PLWH). This cross-sectional study included PLWH with and without T2D (n = 32 total). Analyses involved a multiplex platform for circulating biomarkers and gas chromatography-vacuum ultraviolet spectroscopy for plasma amino acids. In PLWH and T2D, both fibrinogen (2.0 ± 0.6 vs 1.6 ± 0.4 µg/mL, p = 0.02) and von Willebrand factor (vWF) (40.8 ± 17.2 vs 26.7 ± 13.8 µg/mL, p = 0.02) were increased and tryptophan (47 ± 6 vs 53 ± 8 nmol/mL, p = 0.03) and threonine (102 ± 25 vs 125 ± 33 nmol/mL, p = 0.03) were decreased. Fibrinogen, as a biomarker of inflammation, and vWF, as a biomarker of endothelial dysfunction, are augmented by the combined effects of HIV and T2D and may contribute to the pathogenesis of T2D in PLWH. Chronic immune activation and inflammation compromise the integrity of the intestinal mucosa, which increases mucus production. Tryptophan metabolism is altered by a loss of intestinal membrane integrity and threonine is consumed in the production of mucus. Metabolic competition arising from increased protein synthesis in the setting of chronic inflammation along with the associated loss in intestinal membrane integrity may be a primary mechanism in the pathogenesis of T2D in PLWH and requires further investigation.

RESUMO

Purpose The purpose of this systematic review of qualitative literature was (1) to identify self-management strategies, (2) to identify women's barriers to self-management, and (3) to compare self-management strategies of diabetes and human immunodeficiency virus (HIV). African American women living with HIV are at high risk for developing diabetes because of genetics, lifestyle, and HIV treatment. Self-management of each of these conditions is critical to decrease morbidity and mortality. Conclusions A literature search resulted in 15 articles: 10 on the topic of HIV and 5 on diabetes. Self-management strategies included spirituality, family and social support, and indulgent self-care. Barriers included depression, stigma, and the role of caregiver. The themes identified for HIV and diabetes self-care barriers and facilitators were exceptionally similar. Themes of spirituality, family support, and indulgent self-care were part of both HIV and diabetes self-care. Women with HIV were less concerned with their independence than women with diabetes, and focused on disclosure of their HIV status and development of a support system.
