Blood glucose level and serum lipid profiles among people living with HIV on dolutegravir-based versus efavirenz-based cART; a comparative cross-sectional study

Comparative Effects of Efavirenz and Dolutegravir on Metabolomic and Inflammatory Profiles, and Platelet Activation of People Living with HIV: A Pilot Study

Antiretroviral therapy (ART) has reduced the mortality and morbidity associated with HIV. However, irrespective of treatment, people living with HIV remain at a higher risk of developing non-AIDS-associated diseases. In 2019, the World Health Organization recommended the transition from efavirenz (EFV)- to dolutegravir (DTG)-based ART. Data on the impact of this transition are still limited. The current study therefore investigated the metabolic profiles, cytokine inflammatory responses, and platelet activation before and after the treatment transition. Plasma samples from nine virally suppressed adults living with HIV and sixteen healthy, HIV-uninfected individuals residing in Gauteng, South Africa were compared. Metabolite and cytokine profiles, and markers associated with platelet activation, were investigated with untargeted proton magnetic resonance metabolomics, multiplex suspension bead array immunoassays, and sandwich enzyme-linked immunosorbent assays, respectively. In those individuals with normal C-reactive protein levels, the transition to a DTG-based ART regimen resulted in decreased concentrations of acetoacetic acid, creatinine, adenosine monophosphate, 1,7-dimethylxanthine, glycolic acid, 3-hydroxybutyric acid, urea, and lysine. Moreover, increased levels of formic acid, glucose, lactic acid, myo-inositol, valine, glycolic acid, and 3-hydroxybutyric acid were observed. Notably, levels of interleukin-6, platelet-derived growth factor-BB, granulocyte-macrophage colony-stimulating factor, tumor necrosis factor-alpha, soluble cluster of differentiation 40 ligand, as well as regulated on activation, normal T-cell expressed and secreted (RANTES) reached levels close to those observed in the healthy control participants. The elevated concentration of macrophage inflammatory protein-1 alpha was the only marker indicative of elevated levels of inflammation associated with DTG-based treatment. The transition from EFV- to DTG-based regimens therefore appears to be of potential benefit with metabolic and inflammatory markers, as well as those associated with cardiovascular disease and other chronic non-AIDS-related diseases, reaching levels similar to those observed in individuals not living with HIV.

Serum Lipid Profiles, Blood Glucose, and High-Sensitivity C-Reactive Protein Levels Among People Living with HIV Taking Dolutegravir and Ritonavir-Boosted Atazanavir-Based Antiretroviral Therapy at Jimma University Medical Center, Southwest Ethiopia, 2021

Background

Long-term use of antiretroviral therapy, especially dolutegravir and boosted-atazanavir, raises concerns about cardiovascular disease. Thus, this study aimed to assess lipid profiles, blood glucose, and high-sensitivity C-reactive protein levels among people living with HIV on dolutegravir and ritonavir-boosted atazanavir-based therapy.

Methods

An institutional-based comparative cross-sectional study was conducted from November 4, 2021, to January 4, 2022. An equal number of dolutegravir- and ritonavir-boosted atazanavir-treated patients (n = 64 each) was enrolled. A consecutive sampling was used to select participants. The Chi-square, Student's t-test, Mann-Whitney U-test, and logistic regression were used as appropriate statistical tests using SPSS Version 25.0. Statistical significance was set at p < 0.05.

Results

Dyslipidemia was found in 67.2% (43/64) of ritonavir-boosted atazanavir group and 48.4% (31/64) of dolutegravir group. The dolutegravir group had significantly higher mean and median values of high-density lipoprotein and random blood sugar, respectively, as well as lower median triglyceride and high-sensitivity C-reactive protein levels than the ritonavir-boosted atazanavir group. Ritonavir-boosted atazanavir-based regimens (AOR=3.4, 95% CI: 1.5, 8) and age >40 years were predictors of dyslipidemia, while BMI ≥25 kg/m2 (AOR=3.7, 95% CI: 1.3, 10.8) and dolutegravir-based regimens (AOR=4.6, 95% CI: 1.5, 14) were predictors of hyperglycemia. Ritonavir-boosted atazanavir-based regimens (ARR=3, 95% CI: 1.3, 8) and BMI ≥25 kg/m2 (ARR=2.5, 95% CI: 1.1, 6) were associated with increased high-sensitivity C-reactive protein by 1-3 mg/L. The risk of increased high-sensitivity C-reactive protein by >3 mg/L was greater in those patients with a CD4 cell count of <500 cells/mm3 (ARR=5, 95% CI: 1.1, 24).

Conclusion

When compared to ritonavir-boosted atazanavir-based regimens, dolutegravir had favorable lipid profiles and high-sensitivity C-reactive protein but unfavorable blood glucose levels. Therefore, baseline blood glucose, lipid profiles, and high-sensitivity C-reactive protein levels should be routinely measured in patients on these regimens.
