ABSTRACT
Background: Drug-induced kidney injury was among the most common renal damages, from which gentamicin occupies around 25% of this injury. Gentamicin-induced renal damage is caused by increased free radicals with subsequent amplified inflammation. Ajuga remota leaf extract has many phytochemicals with antioxidant activities, which may improve gentamicin-induced renal damage. Thus, we aimed to investigate the nephroprotective effect of Ajuga remota leaf methanolic extract on gentamicin-induced nephrotoxicity in Swiss Albino Mice. Methods: An experimental study design was used on 30 experimental mice randomly allocated in six groups: Group I, II, II, IV, and VI, among which mice were given only distilled water, only gentamicin, 600 mg/kg Ajuga remota leaf extract only, gentamicin along with 200 mg/kg extract, gentamicin with 400 mg/kg extract and gentamicin with 600 mg/kg extract, respectively. At the end of the experiment, the mice were sacrificed after being anaesthetized, and blood samples were collected through a cardiac puncture for renal function tests while the kidneys were removed for histopathological evaluation. The data were entered into Epidata version 4.6 and exported to SPSS version 25 for further analysis using one-way analysis of variance. Statistical significance was set at p < 0.05. Results: Group II mice had significantly higher levels of serum creatinine and blood urea levels compared to group I and III. The body weight of the mice in group V and group VI showed a significant increase compared with Group II. Serum creatinine and blood urea levels were reduced significantly in the Ajuga remota leaf extract administered group of mice compared to group II. Abnormal kidney architectural changes were seen among group II mice; however, those changes were improved after administration of Ajuga remota leaf methanolic extract. Conclusion: Methanol extract of Ajuga remota leaf provided effective protection against gentamicin-induced oxidative renal damage through its antioxidant effects.
ABSTRACT
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.
