Brief Report: Statin Effects on Myocardial Fibrosis Markers in People Living With HIV.

ABSTRACT: BACKGROUND:In observational studies, patients with HIV have higher levels of soluble ST2 (sST2), galectin-3, and growth differentiation factor-15 (GDF-15) than non-HIV controls. As statins exert pleiotropic immunomodulatory effects that may affect markers of myocardial fibrosis, the objective of the current study is to determine whether biomarkers of myocardial fibrosis reflecting subclinical pathology may be modified by statin therapy in patients with HIV. SETTING AND METHODS:Forty HIV+ men and women participated in a single center 12-month randomized, double-blind placebo-controlled trial of atorvastatin 40 mg every day vs. placebo. At baseline and 12-months, sST2, GDF-15, galectin-3 were measured. RESULTS:The changes in sST2 were -0.310 (-4.195, 2.075) vs. 1.163 (0.624, 4.715) ng/mL, median (interquartile range) atorvastatin vs. placebo (P = 0.04). The change in sST2 was significantly related to changes in monocyte activation marker sCD14 (r = 0.63, P < 0.0001) and MCP (r = 0.52, P = 0.0009), markers of generalized inflammation hs-IL-6 (r = 0.58, P = 0.0002), oxLDL (r = 0.49, P = 0.002), and GDF-15 (r = 0.54, P = 0.0008). CONCLUSIONS:sST2, a member of the IL-1 receptor family and a marker of fibrosis and inflammation increases over time among patients with HIV and this increase is attenuated by statin therapy in HIV. This effect may relate to immunomodulatory mechanisms of statins.

Project description:BackgroundHematological malignancies have continued to be highly prevalent among people living with HIV (PLHIV). This study assessed the occurrence of, risk factors for, and outcomes of hematological and nonhematological malignancies in PLHIV in Asia.MethodsIncidence of malignancy after cohort enrollment was evaluated. Factors associated with development of hematological and nonhematological malignancy were analyzed using competing risk regression and survival time using Kaplan-Meier.ResultsOf 7455 patients, 107 patients (1%) developed a malignancy: 34 (0.5%) hematological [0.08 per 100 person-years (/100PY)] and 73 (1%) nonhematological (0.17/100PY). Of the hematological malignancies, non-Hodgkin lymphoma was predominant (n = 26, 76%): immunoblastic (n = 6, 18%), Burkitt (n = 5, 15%), diffuse large B-cell (n = 5, 15%), and unspecified (n = 10, 30%). Others include central nervous system lymphoma (n = 7, 21%) and myelodysplastic syndrome (n = 1, 3%). Nonhematological malignancies were mostly Kaposi sarcoma (n = 12, 16%) and cervical cancer (n = 10, 14%). Risk factors for hematological malignancy included age >50 vs. ≤30 years [subhazard ratio (SHR) = 6.48, 95% confidence interval (CI): 1.79 to 23.43] and being from a high-income vs. a lower-middle-income country (SHR = 3.97, 95% CI: 1.45 to 10.84). Risk was reduced with CD4 351-500 cells/µL (SHR = 0.20, 95% CI: 0.05 to 0.74) and CD4 >500 cells/µL (SHR = 0.14, 95% CI: 0.04 to 0.78), compared to CD4 ≤200 cells/µL. Similar risk factors were seen for nonhematological malignancy, with prior AIDS diagnosis showing a weak association. Patients diagnosed with a hematological malignancy had shorter survival time compared to patients diagnosed with a nonhematological malignancy.ConclusionsNonhematological malignancies were common but non-Hodgkin lymphoma was more predominant in our cohort. PLHIV from high-income countries were more likely to be diagnosed, indicating a potential underdiagnosis of cancer in low-income settings.
