Short-term Increase in Risk of Overweight and Concomitant Systolic Blood Pressure Elevation in Treatment-Naive Persons Starting INSTI-Based Antiretroviral Therapy.

ABSTRACT: Objective:Integrase strand transfer inhibitors (INSTI) have been associated with weight gain, but their effect on short-term overweight and obesity incidence, blood pressure (BP), and metabolic markers has not been described in treatment-naïve people with HIV(PWH). Method:Medical records of treatment-naïve persons starting antiretroviral therapy (ART) at the HIV Clinic of University Hospital of Elche, Spain, between January 2007 and July 2019 were reviewed retrospectively. Standard procedures included measurements of weight, BP, and metabolic assessment. Data at baseline, 48, 72, and 96 weeks post ART initiation were analyzed. We used Cox mixed-effects model to generate predictions of body mass index (BMI) over time and generalized additive mixed models to relax the linearity assumptions and generate 95% confidence intervals in the multivariable adjustment. Results:Among 219 (median age, 44.0 years; interquartile range [IQR], 37.0-53.5; 46 females) participants. Baseline weight mean (standard deviation) was 70.4 (13.7) kg without difference between regimens; 66% had a BMI <25 kg/mt2. The incidence of overweight and obesity was significantly greater in persons starting INSTI-based regimens: 15 (36.6%) of 41 patients treated with INSTI versus 30 (28.9%) of 104 treated with other ART regimens (hazard ratio, 2.3; 95% CI, 1.2-4.4; P = .011). In contrast to other ART regimens, patients treated with INSTI showed a significant increase in systolic BP (SBP) (adjusted increase, 7.0 mmHg; 95% CI, 0.3-13.7; P = .039) that was correlated with weight gain (r = 0.13; 95% CI, 0.10-0.16; P < .001). Patients who reached overweight and obesity in INSTI-based ART showed a significant increase in LDL cholesterol. Conclusions:Integrase strand transfer inhibitors-based ART was associated in the short-term with a greater risk of overweight and obesity and SBP elevation. Patients developing overweight and obesity increased low-density lipoprotein cholesterol with no other metabolic disturbances.

Project description:ObjectiveTo assess the effect of HIV infection and combined antiretroviral therapy (c-ART) on various proatherogenic biomarkers and lipids and to investigate their relationship with subclinical atherosclerosis in a cohort of treatment-naive HIV-infected patients.MethodsWe performed a prospective, comparative, multicenter study of 2 groups of treatment-naive HIV-infected patients (group A, CD4>500 cells/μL, not starting c-ART; and group B, CD4<500 cells/μL, starting c-ART at baseline) and a healthy control group. Laboratory analyses and carotid ultrasound were performed at baseline and at months 12 and 24. The parameters measured were low-density lipoprotein (LDL) particle phenotype, lipoprotein-associated phospholipase A2 (Lp-PLA2), interleukin-6 (IL-6), high-sensitivity C-reactive protein (hs-CRP), sCD14, sCD163, monocyte chemoattractant protein-1(MCP-1), and asymmetric dimethylarginine (ADMA). A linear mixed model based on patient clusters was used to assess differences in biomarkers between the study groups and over time.ResultsThe study population comprised 62 HIV-infected patients (group A, n = 31; group B, n = 31) and 22 controls. Age was 37 (30-43) years, and 81% were men. At baseline, the HIV-infected patients had a worse LDL particle phenotype and higher plasma concentration of sCD14, sCD163, hs-CRP, and LDL-Lp-PLA2 than the controls. At month 12, there was an increase in total cholesterol (p = 0.002), HDL-c (p = 0.003), and Apo A-I (p = 0.049) and a decrease in sCD14 (p = <0.001) and sCD163 (p<0.001), although only in group B. LDL particle size increased in group B at month 24 (p = 0.038). No changes were observed in group A or in the healthy controls. Common carotid intima-media thickness increased in HIV-infected patients at month 24 (Group A p = 0.053; group B p = 0.048). Plasma levels of sCD14, sCD163, and hs-CRP correlated with lipid values.ConclusionsIn treatment-naive HIV-infected patients, initiation of c-ART was associated with an improvement in LDL particle phenotype and inflammatory/immune biomarkers, reaching values similar to those of the controls. HIV infection was associated with progression of carotid intima-media thickness.

Project description:BackgroundNon-alcoholic Fatty Liver Disease (NAFLD) has a high prevalence among persons with HIV infection. Since Integrase Strand Transfer Inhibitors (INSTIs) are used worldwide and have been associated with weight gain, we must determine their effect in the development of NAFLD and Non-alcoholic Steatohepatitis (NASH) in these patients. The aim of this study was to explore the impact of INSTIs on variation of liver steatosis and fibrosis in the ART-naïve person with HIV, using Hepatic Steatosis Index (HSI), Fibrosis-4 Index (FIB-4), BARD score and NAFLD Fibrosis Score (NFS).MethodsWe performed a monocentric, retrospective cohort study in ART-naïve persons with HIV that initiated INSTI based regimens between December 2019 and January 2022. Data was collected at baseline, 6 and 12 months after initiation. Demographic, clinical and laboratory characteristics, hepatic steatosis, and fibrosis scores were compared between baseline and last visit at 12 months. Linear regression models were performed to analyse the associations between analytical data at baseline and hepatic scores variation during the 12 months of treatment. Models were performed unadjusted and adjusted for age and sex.Results99 patients were included in our study. 82% were male and median age was 36 years. We observed a significant increase in body mass index (BMI), HDL, platelet count, albumin, and creatinine and a significant decrease in AST levels. HSI showed no statistically significant differences during follow-up (p = 0.114). We observed a significant decrease in FIB-4 (p = 0.007) and NFS (p = 0.002). BARD score showed a significant increase (p = 0.006). The linear regression model demonstrated a significant negative association between baseline HIV RNA and FIB-4 change (β= -0.08, 95% CI [-0.16 to -0.00], p = 0.045), suggesting that higher HIV RNA loads at baseline were associated with a greater decrease in FIB-4.ConclusionINSTIs seem to have no impact on hepatic steatosis, even though they were associated with a significant increase in BMI. This might be explained by the direct effect of a dolutegravir-containing regimen and/or by the "return-to-health effect" observed with ART initiation. Furthermore, INSTIs were associated with a reduction in risk of liver fibrosis in ART-naïve persons with HIV, possibly due to their effect on viral suppression.

Project description:HIV-1 transmitted drug resistance (TDR) is of increasing public health concern in sub-Saharan Africa with the rollout of antiretroviral (ARV) therapy. Such data are, however, limited in Kenya, where HIV-1 drug resistance testing is not routinely performed. From a population-based household survey conducted between September and November 2012 in rural western Kenya, we retrospectively assessed HIV-1 TDR baseline rates, its determinants, and genetic diversity among drug-naïve persons aged 15-59 years with acute HIV-1 infections (AHI) and recent HIV-1 infections (RHI) as determined by nucleic acid amplification test and both Limiting Antigen and BioRad avidity immunoassays, respectively. HIV-1 pol sequences were scored for drug resistance mutations using Stanford HIVdb and WHO 2009 mutation guidelines. HIV-1 subtyping was computed in MEGA6. Eighty seven (93.5%) of the eligible samples were successfully sequenced. Of these, 8 had at least one TDR mutation, resulting in a TDR prevalence of 9.2% (95% CI 4.7-17.1). No TDR was observed among persons with AHI (n = 7). TDR prevalence was 4.6% (95% CI 1.8-11.2) for nucleoside reverse transcriptase inhibitors (NRTIs), 6.9% (95% CI 3.2-14.2) for non- nucleoside reverse transcriptase inhibitors (NNRTIs), and 1.2% (95% CI 0.2-6.2) for protease inhibitors. Three (3.4% 95% CI 0.8-10.1) persons had dual-class NRTI/NNRTI resistance. Predominant TDR mutations in the reverse transcriptase included K103N/S (4.6%) and M184V (2.3%); only M46I/L (1.1%) occurred in the protease. All the eight persons were predicted to have different grades of resistance to the ARV regimens, ranging from potential low-level to high-level resistance. HIV-1 subtype distribution was heterogeneous: A (57.5%), C (6.9%), D (21.8%), G (2.3%), and circulating recombinant forms (11.5%). Only low CD4 count was associated with TDR (p = 0.0145). Our findings warrant the need for enhanced HIV-1 TDR monitoring in order to inform on population-based therapeutic guidelines and public health interventions.
