Abstract
Tenofovir disoproxil fumarate (TDF) is an antiretroviral drug widely used as part of antiretroviral therapy (ART) to treat human immunodeficiency virus (HIV-1) infection. Negative effects of tenofovir include impaired kidney function, especially with long-term use. In studies conducted among HIV-positive individuals, we found evidence of extensive kidney damage associated with TDF use. Despite the therapeutic importance of this consequence, its continued use in ART regimens was not contraindicated. The therapeutic and long-term effects of TDF are a major concern. However, in countries or settings where resources are limited and renal function monitoring cannot be ensured, screening methods to detect ART-related renal failure are still supported by data. Therefore, it is safe to re-evaluate the use of TDF-based ART. However, adherence to guidelines may be hampered by insufficient laboratory testing in low- and middle-income countries. More research is also needed among people under 18 years of age and pregnant and breastfeeding mothers.

Abstract
INTRODUCTION Tenofovir alafenamide (TAF), a prodrug of tenofovir, achieves higher intracellular concentrations of tenofovir-diphosphate and 90% lower plasma concentrations of tenofovir compared to tenofovir disoproxil fumarate (TDF). TAF is associated with improved renal and bone safety outcomes. AREAS COVERED We review the efficacy and safety of TAF-containing regimens in adults and pediatrics. We highlight safety data during pregnancy, drug interactions during co-administration with tuberculosis treatment, and critical knowledge gaps to be addressed for the successful implementation of TAF in low- and middle-income countries. We performed a search on MEDLINE PubMed and conference websites for relevant articles published from January 2010 to March 2023. EXPERT OPINION Current evidence demonstrates that TAF has similar efficacy and tolerability, superior bone and renal safety, and higher rates of dyslipidemia and weight gain, compared with TDF. However, there are several knowledge gaps, in specific sub-populations, that require action. Emerging data suggests that TAF is safe during pregnancy, although fuller safety data to support TAF use in pregnancy is needed. Similarly, there is a lack of evidence that TAF can be used in combination with rifamycin-based tuberculosis treatment in PWH and TB. Further studies are needed to fill knowledge gaps and support the wider rollout of TAF.

Renal Function Impairment and Associated Factors Among Adult HIV-Positive Patients Attending Antiretroviral Therapy Clinic in Mettu Karl Referral Hospital: Cross-Sectional Study. HIV AIDS (Auckl) 2021; 13:631-640. [PMID: 34135641 PMCID: PMC8200135 DOI: 10.2147/hiv.s301748] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Accepted: 05/19/2021] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Human immunodeficiency virus (HIV) affects every organ system in the body through impairment or by rendering the patient vulnerable to opportunistic infections. The kidney is the vital organ in the excretion of waste products and toxins (urea, creatinine and uric acid), and regulation of extracellular fluid volume, serum osmolality and electrolyte concentrations. The risk of kidney disease is greater in HIV-infected individuals than in the general population. This study aimed to assess the magnitude of renal function impairment and its associated factors among adult HIV-positive patients attending an ART clinic in Mettu Karl Referral Hospital, Mettu town, south-west Ethiopia. METHODS The institution-based, cross-sectional quantitative study was conducted from March 8 to May 30, 2020. A total of 352 clients participated and a systematic sampling technique was used to allocate study participants. Data were entered into Epi data and exported to SPSS version 22 for analysis. Bivariate analysis was conducted to identify candidate variables for multivariate analysis at P <0.25. Multivariable logistic regression analysis was conducted to determine the predictors of renal function impairment with ART. P value < 0.05 was considered to indicate statistical significance. RESULTS A total of 352 HIV-infected patients participated in this study with a response rate of 98.1%. Out of 352 HIV patients on ART, 73 (20.7%) were found to have renal function impairment. Cigarette smoking [AOR = 9.60, 95% CI: 4.73-19.48], diabetes mellitus [AOR = 6.16, 95% CI: 2.79-13.59], hypertension [AOR = 4.71, 95% CI: 1.98-11.17] and low CD4 count [AOR = 6.47, 95% CI: 3.31-12.64] were found to be independent predictors of renal function impairment among adult HIV positive patients. CONCLUSION The prevalence of renal function impairment among HIV patients on ART is high. Hypertension, diabetes, cigarette smoking and low CD4 count were associated factors of renal function impairment. HIV patients on ART should be regularly screened for early diagnosis and management of renal function impairment.

HIV AIDS (Auckl) 2021; 13:491-503. [PMID: 34007217 PMCID: PMC8123951 DOI: 10.2147/hiv.s308339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Accepted: 04/14/2021] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND The use of tenofovir disoproxil fumarate (TDF) has been reported to be a significant contributor to renal dysfunction. However, patients in Ethiopia may be different than in other parts of the world, and findings from such studies may not apply in this setting. OBJECTIVE This study aimed to assess TDF-associated renal dysfunction among adult people living with HIV (PLHIV) at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia. METHODS This retrospective cohort study included adult PLHIV between January 2015 and June 2019. The Chronic Kidney Disease Epidemiology (CKD-EPI) equation was used to estimate glomerular filtration rate (eGFR). Renal dysfunction was defined as eGFR <60 mL/min/1.73 m2. Data were entered into Epi Info™ 7 and analyzed by using SPSS® software version 20. The Kaplan-Meier method was used to estimate the survival curves. Cox proportional hazards models were used to identify predictors of renal dysfunction using a 95% confidence interval and p-value ≤ 0.05 as a statistical significance. RESULTS Out of 400 participants, 200 were TDF-based ART groups, and 200 were non-TDF-based ART groups. The incidence of renal dysfunction of TDF and the non-TDF group was 28.31 per 100 person-years (PYs) and 12.53 per 100 PYs, respectively. Adult PLHIV taking TDF-based regimens were 1.70 (adjusted HR = 1.70; 95% CI = 1.02-2.82) times at higher risk of renal dysfunction than non-TDF-based regimens. Age ≥55, diabetes mellitus, concurrent nephrotoxic drug use, and combined use of ritonavir-boosted protease inhibitors were also associated significantly with renal dysfunction. CONCLUSION The incidence rate of renal dysfunction among TDF users is higher than non-TDF users. Exposure to TDF is a significant risk of renal dysfunction in adult PLHIV. Clinicians should regularly monitor the renal function of adult PLHIV who are taking TDF.

HIV AIDS-RESEARCH AND PALLIATIVE CARE 2021; 13:301-306. [PMID: 33758552 PMCID: PMC7981141 DOI: 10.2147/hiv.s299596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/29/2020] [Accepted: 03/04/2021] [Indexed: 11/23/2022]
Abstract
Background Life expectancy of HIV patients has increased by the extensive use of antiretroviral therapies (ART), but ART predisposes patients to chronic non-communicable diseases including chronic kidney disease (CKD). Tenofovir disoproxil fumarate is one of the commonly used drugs in ART and is found to have more risk for developing CKD. In the study areas, there was no previous study addressing the prevalence of CKD, so the purpose of this study was to pinpoint the prevalence of CKD, and its associated factors. Methods A hospital-based cross-sectional study was employed at Tikur Anbessa Specialized Hospital (TASH) and Zewuditu Memorial Hospital (ZMH) from April 1 to June 30, 2019. The study participants were proportionally allocated to each hospital and a total of 243 eligible participants were selected conveniently from the two hospitals in the study period. Structured questionnaire and checklist were used to collect socio-demographic and clinical data of the participants. Blood samples (3–5 ml) were used to determine serum creatinine using calibrated fully automated Mind ray BS-200E, and glomerular filtration rate (GFR) was estimated using a chronic kidney disease epidemiology equation. Multivariate logistic regression was employed to identify factors associated with CKD, and a P-value of less than 0.05 was considered significant. Results In the present study, the prevalence of CKD (GFR <60 ml/min/1.73 m2) was 4.53% (95% CI = 2.3–8%). GFR was classified into stages, stage 5 (GFR <15), stage 4 (15–29.9), stage 3 (30–59.9), stage 2 (60–89.9), and stage 1 (≥90) were 0%, 0.4%, 4.1%, 38.3%, and 57.2%, respectively. In the multivariate logistic regression, age greater than 50 years old, and having cancer were significantly associated with CKD (AOR: 0.22, 95% CI = 0.05–0.88, P = 0.033, and AOR: 18.20, 95% CI = 122–271.77, P = 0.035, respectively). Conclusion Chronic kidney disease in HIV-infected patients receiving a TDF-based regimen requires attention. Age >50 years old, and having cancer as comorbidity were significantly associated with chronic kidney disease. Patients should be regularly monitored for early diagnosis and management of chronic kidney disease in a TDF-based regimen.

[PMID: 33481839 PMCID: PMC7822244 DOI: 10.1371/journal.pone.0245500] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Accepted: 12/30/2020] [Indexed: 12/26/2022] Open
Abstract
Aim To evaluate the prevalence and associated factors of abnormal renal function among Ethiopian HIV-infected patients at baseline prior to initiation of antiretroviral therapy (ART) and during follow-up. Methods We conducted a retrospective observational cohort study of HIV infected patients who initiated ART at the outpatient ART clinic of Mehal Meda Hospital of North Shewa, Ethiopia from January 2012 to August 2018. Demographic and clinical data were abstracted from the medical records of patients. Renal function was assessed by estimated glomerular filtration rate (eGFR) calculated using the Modification of Diet in Renal Disease (MDRD) equation. Univariate and multivariate analysis were conducted to determine the factors associated with abnormal renal function at baseline and during follow-up. Results Among 353 patients, 70 (19.8%) had baseline eGFR <60 ml/min/1.73m2 and 102 (28.9%) had eGFR = 60–89.9 ml/min/1.73m2. Factors associated with baseline renal impairment (eGFR <60 ml/min/1.73m2) included female sex (AOR = 3.52, CI 1.75–7.09), CD4 count < 200 cells/mm3 (AOR = 2.75, CI 1.40–5.42), BMI < 25 Kg/m2 (AOR = 3.04, CI 1.15–8.92), low hemoglobin (AOR = 2.19, CI 1.16–4.09) and high total cholesterol (AOR = 3.15, CI 1.68–5.92). After a median of 3.0 years of ART, the mean eGFR declined from 112.9 ± 81.2 ml/min/1.73m2 at baseline to 93.9 ± 60.6 ml/min/1.73m2 (P < 0.001). The prevalence of renal impairment increased from 19.8% at baseline to 22.1% during follow-up. Of 181 patients with baseline normal renal function, 49.7% experienced some degree of renal impairment. Older age (AOR = 3.85, 95% CI 2.03–7.31), female sex (AOR = 4.18, 95% CI 2.08–8.40), low baseline CD4 (AOR = 2.41, 95% CI 1.24–4.69), low current CD4 count (AOR = 2.32, 95% CI 1.15–4.68), high BMI (AOR = 2.91, 95% CI 1.49–5.71), and low hemoglobin (AOR = 3.38, 95% CI 2.00–7.46) were the factors associated with renal impairment during follow-up. Conclusion Impaired renal function was common in HIV-infected patients initiating ART in an outpatient setting in Ethiopia, and there appears to be a high prevalence of renal impairment after a median ART follow-up of 3 years. There is a need for assessment of renal function at baseline before ART initiation and regular monitoring of renal function for patients with HIV during follow-up.

Determinants of Risk Factors for Renal Impairment among HIV-Infected Patients Treated with Tenofovir Disoproxil Fumarate-Based Antiretroviral Regimen in Southern Vietnam. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7650104. [PMID: 32382572 PMCID: PMC7199550 DOI: 10.1155/2020/7650104] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Revised: 12/14/2019] [Accepted: 12/23/2019] [Indexed: 01/02/2023]
Abstract
Background The situation of renal impairment among HIV-infected patients treated with TDF-based antiretroviral (ARV) regimen greater than 3 years is little known when TDF use has been promptly increasing in Vietnam. Methods We analyse demographic and clinical data from a cross-sectional survey of 400 HIV-infected patients aged ≥18 years, who were treatment-naive or switched TDF regimen within over 3 years between November 2018 and March 2019. Serological tests for serum creatinine, ALT, and AST were performed. Renal impairment was defined as an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2. Multivariate regression analyses were used to explore the risk factors associated with renal impairment. Results At the baseline, 7.8% of respondents had estimated glomerular filtration rate (eGFR) of 30-59 mL/min/1.73 m2 and 0.8% had eGFR of 15-29 mL/min/1.73 m2, out of 34 (8.5%) of participants who had renal impairment. Multivariate analysis showed that participants who had preexposure to isoniazid (adjusted PR [aPR] = 0.35 Cl: 0.14-0.91) compared with nonexposure to isoniazid who had a BMI from 18.5 up to 25 kg/m2 (aPR = 0.31 Cl: 0.15-0.62) compared with BMI below 18.5 kg/m2 were less likely to suffer from renal impairment. Patients aged greater than 60 years (aPR = 26.75, 95% Cl: 3.38-211.62) compared with those aged 20-29 years were more likely to have increased risk of renal impairment. Conclusion Our findings underscore the need for longitudinal studies to assess the influence of TDF on maintaining the low prevalence of renal impairment among HIV-infected patients in Vietnam.
