Abstract
Long-term use of tenofovir disoproxil fumarate (TDF) can induce renal dysfunction that requires TDF dose reduction. Previous studies showed that systemic drug use exerts a threefold higher risk of moderate renal impairment. This study aimed to compare viral control between two tenofovir dose reduction regimens in chronic hepatitis B (CHB) patients with moderate renal impairment from TDF-induced renal dysfunction. This noninferiority, randomized controlled study was conducted at the Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand. Virologically suppressed CHB patients treated with TDF who had moderate renal impairment were randomly allocated to receive TDF 300 mg either every 48 or 72 hours. Forty-six patients (67.4% male) with a mean age of 62.8 ± 7.8 years were enrolled. Among all patients, 34.8% were HBeAg-positive, and 23.9% had cirrhosis. All included patients completed 12 months of follow-up. No patients had virological breakthrough. After dose reduction, estimated glomerular filtration rate (eGFR) was improved in both groups, but a higher proportion of patients had an eGFR > 60 mL/min/1.73 m2 in the TDF every 72 hours group. Other renal parameters, including serum phosphate, tubular maximal reabsorption for phosphate per GFR, urine protein-to-creatinine ratio, urine sugar and urine neutrophil gelatinase-associated lipocalin, were not significantly different between groups. Among TDF-treated CHB patients with TDF-induced moderate renal impairment, more aggressive dose reduction in TDF from every 48 hours to every 72 hours did not affect virological breakthrough. A higher proportion of patients in the TDF every 72 hours group had improvement in renal function.

Abstract
Background The clinical epidemiology of treated HIV infection in the United States has dramatically changed in the past 25 years. Few sources of longitudinal data exist for people with HIV (PWH) spanning that period. Cohort data enable investigating new exposure and disease associations and monitoring progress along the HIV care continuum. Methods We synthesized key published findings and conducted primary data analyses in the HIV Outpatient Study (HOPS), an open cohort of PWH seen at public and private HIV clinics since 1993. We assessed temporal trends in health outcomes (1993-2017) and mortality (1994-2017) for 10 566 HOPS participants. Results The HOPS contributed to characterizing new conditions (eg, lipodystrophy), demonstrated reduced mortality with earlier HIV treatment, uncovered associations between select antiretroviral agents and cardiovascular disease, and documented remarkable shifts in morbidity from AIDS opportunistic infections to chronic noncommunicable diseases. The median CD4 cell count of participants increased from 244 cells/mm3 to 640 cells/mm3 from 1993 to 2017. Mortality fell from 121 to 16 per 1000 person-years from 1994 to 2017 (P < .001). In 2010, 83.7% of HOPS participants had a most recent HIV viral load <200 copies/mL, compared with 92.2% in 2017. Conclusions Since 1993, the HOPS has been detecting emerging issues and challenges in HIV disease management. HOPS data can also be used for monitoring trends in infectious and chronic diseases, immunologic and viral suppression status, retention in care, and survival, thereby informing progress toward the Ending the HIV Epidemic initiative.

Abstract
Background HIV-infected patients have an increased risk of renal disease. Current first-line antiretroviral therapy contains tenofovir disoproxil fumarate (TDF), which has nephrotoxic potential, characterised by proximal tubular cell injury. This may result in acute kidney injury, chronic kidney disease or partial or complete Fanconi syndrome. Objectives We reviewed the existing literature on acute kidney injury and TDF-associated nephrotoxicity with the aim of providing an approach to diagnosis and management, which is relevant to a general medical practitioner. Methods We performed a broad literature search of biomedical databases including PubMed and ScienceDirect. Our search terms included, but were not limited to, ‘tenofovir’, ‘nephrotoxicity’, ‘HIV’, ‘acute kidney injury’ and ‘renal tubular acidosis’. Our aim was not to generate a systematic literature review with weighted evidence, but rather to provide a review of best practice from a variety of sources. Where published studies were not available from the above databases, we relied on relevant textbooks and professional guidelines. Results Potential nephrotoxicity is not an impediment to the widespread use of TDF in treating HIV infection, because most patients will tolerate the medication well. However, patients with advanced disease, low body weight, advanced age, pre-existing kidney disease and concomitant use of other nephrotoxic medications are at increased risk of adverse renal events and may develop severe complications if not appropriately managed. These risk factors are unfortunately common in patients initiating antiretroviral therapy in South Africa. Conclusion Prevention of renal damage by means of careful screening and monitoring of high-risk patients is of paramount importance. Increased awareness of this problem and knowledge of how to manage kidney disease should be emphasised for general medical practitioners who work with HIV-infected patients.

Association of tenofovir disoproxil fumarate with primary allograft survival in HIV-positive kidney transplant recipients. Transpl Infect Dis 2017; 19. [PMID: 28520146 DOI: 10.1111/tid.12727] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2016] [Revised: 03/09/2017] [Accepted: 03/18/2017] [Indexed: 12/29/2022]
Abstract
BACKGROUND Tenofovir disoproxil fumarate (TDF) is an antiretroviral agent frequently used to treat human immunodeficiency virus (HIV). There are concerns regarding its potential to cause acute kidney injury, chronic kidney disease, and proximal tubulopathy. Although TDF can effectively suppress HIV after kidney transplantation, it is unknown whether use of TDF-based antiretroviral therapy (ART) after kidney transplantation adversely affects allograft survival. METHODS We examined 104 HIV+ kidney transplant (KT) recipients at our center between 2001 and 2014. We generated a propensity score for TDF treatment using recipient and donor characteristics. We then fit Cox proportional hazards models to investigate the association between TDF treatment and 3-year, death-censored primary allograft failure, adjusting for the propensity score and delayed graft function (DGF). RESULTS Of the 104 HIV+ KT candidates who underwent transplantation during the study period, 23 (22%) were maintained on TDF-based ART at the time of transplantation, and 81 (78%) were on non-TDF-based ART. Median age of the cohort was 48 years; 87% were male; 88% were black; and median CD4 count at transplantation was 450 cells/mm3 . Median kidney donor risk index was 1.2. At 3 years post transplantation, primary allograft failure occurred in 26% of patients on TDF-based ART and in 28% of patients on non-TDF-based ART (P=.5). TDF treatment was not associated with primary allograft failure at 3 years post transplant after adjusting for DGF and a propensity score for TDF use (hazard ratio 2.12, 95% confidence interval 0.41-10.9). CONCLUSIONS In a large single-center experience of HIV+ kidney transplantation, TDF use following kidney transplantation was not significantly associated with primary allograft failure. These results may help inform management for HIV+ KT recipients in need of TDF therapy for adequate viral suppression.

PLoS One 2016; 11:e0149562. [PMID: 26872144 PMCID: PMC4752319 DOI: 10.1371/journal.pone.0149562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2015] [Accepted: 02/01/2016] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Risk factors for and optimal surveillance of renal dysfunction in patients on tenofovir disoproxil fumarate (TDF) remain unclear. We investigated whether a urine protein-osmolality (P/O) ratio would be associated with renal dysfunction in HIV-infected persons on TDF. METHODS This retrospective, single-center study investigated the relationship between parameters of renal function (estimated glomerular filtration rate (eGFR) and P/O-ratio) and risk factors for development of kidney dysfunction. Subjects were HIV-infected adults receiving TDF with at least one urinalysis and serum creatinine performed between 2010 and 2013. Regression analyses were used to analyze risk factors associated with abnormal P/O-ratio and abnormal eGFR during TDF therapy. RESULTS Patients were predominately male (81%); (65%) were Caucasian. Mean age was 45.1(±11.8) years; median [IQR] TDF duration was 3.3 years. [1.5-7.6]. Median CD4+ T cell count and HIV viral load were 451 cells/μL [267.5-721.5] and 62 copies/mL [0-40,150], respectively. Abnormal P/O-ratio was not associated with low eGFR. 68% of subjects had an abnormal P/O-ratio and 9% had low eGFR. Duration of TDF use, age, diabetes and hypertension were associated with renal dysfunction in this study. After adjustment for age, subjects on TDF > 5 years had almost a four-fold increased likelihood of having an abnormal P/O-ratio than subjects on TDF for < 1yr (OR 3.9; 95% CI 1.2-14.0; p = 0.024). CONCLUSION Abnormal P/O-ratio is common in HIV-infected patients on TDF but was not significantly associated with low eGFR, suggesting that abnormal P/O-ratio may be a very early biomarker of decreased renal function in HIV infected patients.

Abstract
OBJECTIVES Our aim is to describe the impact of emtricitabine (FTC)/tenofovir (TDF) versus other nucleoside reverse transcriptase inhibitor (NRTIs)-based regimens on renal function of human immunodeficiency virus (HIV) naïve patients >50 years old who started combination antiretroviral therapy (cART). DESIGN National, retrospective cohort analysis of patients >50 years old when they started cART (January 1, 2006-December 31, 2009). METHODS We compared renal safety (changes in estimated glomerular filtration rate [eGFR] during the first year, and time to renal events during 4 years of follow-up) in FTC/TDF versus non-FTC/TDF users. Among FTC/TDF users, we compared protease inhibitors vs non-nucleoside reverse transcriptase inhibitors and Lopinavir/ritonavir vs Efavirenz. RESULTS We included 103 patients: median age: 54.9 years, 84% males, median CD4 count 247 cells/μl, median viral load 4.7 log; median follow up 18 months (max: 48 months); 73 started with FTC/TDF and 30 with other NRTIs. Change in eGFR was significantly worse for ritonavir-boosted lopinavir (LPV/r) vs efavirenz (EFV) users in the FTC/TDF group (71.2 vs 98.9 ml/min/1.73 m(2) at month 12, P < 0.05). The risk of renal events (progression to an Chronic Kidney Disease Epidemiology Collaboration value < 60 ml/min/1.73 m(2) in subjects with baseline values >60) was comparable for FTC/TDF users and non users, but was higher and almost significant for LPV/r as compared to EFV users in the FTC/TDF group (adjusted hazard ratio 6.1, 95% CI 0.8-45.5). CONCLUSIONS In our study with a population of HIV infected subjects ≥ 50 years old, renal safety was similar for FTC/TDF and other NRTI-based regimens, but worse for LPV/r as compared to other regimens.

Abstract
The prevalence of human immunodeficiency virus (HIV) infection in older and elderly adults is significant worldwide. This population poses new challenges and opportunities in the management of HIV. In addition to the risks affecting HIV patients of all ages, including risk of opportunistic infection and medication resistance, age-related changes in physiology, higher comorbidity burdens, increased use of medications, and potential adverse drug reactions to HIV medications all factor into the care of older adults with HIV. The risk and progression of cardiovascular and renal comorbidities may be higher in the older adult HIV population and in patients taking specific HIV medications. Understanding these risks is essential when managing a new type of patient: the older adult with HIV.

Abstract
In human immunodeficiency virus (HIV)-infected people kidney disease is as an important cause of morbidity and mortality. Clinical features of kidney damage in HIV-infected patients range from asymptomatic microalbuminuria to nephrotic syndrome. The lack of specific clinical features despite the presence of heavy proteinuria may mask the renal involvement. Indeed, it is important in HIV patients to monitor renal function to early discover a possible kidney injury. After the introduction of antiretroviral therapy, mortality and morbidity associated to HIV-infection have shown a substantial reduction, although a variety of side effects for long-term use of highly active antiretroviral therapy, including renal toxicity, has emerged. Among more than 20 currently available antiretroviral agents, many of them can occasionally cause reversible or irreversible nephrotoxicity. At now, three antiretroviral agents, i.e., indinavir, atazanavir and tenofovir disoproxil fumarate have a well established association with direct nephrotoxicity. This review focuses on major causes of proteinuria and other pathological findings related to kidney disease in HIV-infected children and adolescents.

Abstract
Background The Malawian government recently changed its prevention of mother-to-child transmission (PMTCT) regimen and plans to change its first-line antiretroviral therapy (ART) regimen to Tenofovir(TDF)/Lamivudine/Efavirenz as a fixed-dose combination tablet. Implementation could be challenging if baseline creatinine clearance (CrCl) screening were required to assess renal function prior to TDF therapy. Our goal is to determine predictors of CrCl<50 ml/min among HIV-infected, ART-naïve individuals. Methodology Data on HIV-infected, ART-naïve adults screened for enrollment into 5 HIV clinical trials in Lilongwe, Malawi were combined for a pooled analysis of predictors for CrCl<50 ml/min. CrCl was derived from the Cockroft-Gault equation. Multivariable logistic regression modeled the association of age, body mass index (BMI), hemoglobin, CD4 cell count <350 cells/mm3, gender, and pregnancy with CrCl<50 ml/min. Results The analysis included 3508 patients with values for creatinine clearance. Most subjects were female (90.6%) with a median age of 26 years (IQR 22–29). The median CD4 cell count was 444 (IQR 298.0–561.0), and 85.2% percent of women in our study were pregnant. Few patients had CrCl<50 ml/min (n = 38, 1.1%). A BMI less than 18.5 in non-pregnant females (OR = 8.87, 95% CI = 2.45–32.09)) was associated with CrCl<50 ml/min. Hemoglobin level higher than 10 g/dL in males (OR = 0.69, 95% CI = 0.56–0.86) and non-pregnant females (OR = 0.21, 95% CI = 0.04–0.97) was protective against CrCl<50 ml/min. Discussion Our findings indicate few patients would be excluded from a TDF-based antiretroviral regimen, suggesting baseline creatinine clearance assessment may not be necessary for implementation. However, in ART settings individuals with low BMI or anemia could potentially be at increased risk for lower CrCl.

Abstract
With the rapid scale up of antiretroviral therapy, there is a dramatic decline in HIV related morbidity and mortality in both developed and developing countries. Several new safe antiretroviral, and newer class of drugs and monitoring assays are developed recently. As a result the treatment guideline for the management of HIV disease continue to change. This review focuses on evolving science on Indian policy - antiretroviral therapy initiation, which drugs to start with, when to change the initial regimen and what to change.

Abstract
Most patients (80-90%) newly diagnosed with HIV are started on the antiretroviral regimen efavirenz, emtricitabine, and tenofovir (EFV/FTC/TDF). Existing studies of patient tolerability, however, are limited. We compared symptom experiences of patients on EFV/FTC/TDF, and the subsequent impact on health-related quality of life, with those of patients on other combination antiretroviral therapy (cART). We conducted a cross-sectional analysis of the Veterans Aging Cohort Study from February 2008 to August 2009 to compare the symptom experiences of patients on EFV/FTC/TDF vs. other cART, unadjusted and then adjusted for treatment characteristics, and comorbid disease severity. We then assessed the association between EFV/FTC/TDF use and health-related quality of life. Among the 1,759 patients in our analytic sample, EFV/FTC/TDF use was associated with fewer symptoms than was other cART. The use of EFV/FTC/TDF was independently associated with health-related quality of life, and this association was at least partially explained by symptom burden.

Abstract
Tenofovir disoproxil fumerate (TDF) is an effective nucleoside reverse transcriptase inhibitor for HIV infection but it is potentially nephrotoxic. A selective mithochondrial toxicity has been hypothesized. To assess early markers of renal toxicity, we evaluated a cohort of antiretroviral (ARV)-experienced HIV patients who had been switched from a thymidinic backbone to either a TDF/emtricitabine regimen (TDF; 73 patients) or an abacavir/lamivudine (ABV) regimen (28 patients). Markers of mitochondrial toxicity (cytochrome c, Cyc) or cytosolic (α-glutathione S transferase, α-GST) together with common indicators of renal damage were assessed at baseline (T0) and after 1 (T1), 3 (T2), 6 (T3), and 12 (T4) months of patient exposure to therapy. Clinical features of both groups were comparable at T0. There was no significant variation in estimated glomerular filtration rate (eGRF), median urine protein excretion, or microalbuminuria and serum phosphate levels in both groups during the study period. There was a significant increase in urinary excretion of phosphate in patients on TDF compared to those on ABV at T3 and T4. Fractional excretion of uric acid was also altered in the two treatment groups; there was no change in the ABV (constantly less than 0.10), but a progressive increase in TDF patients. Serum potassium levels were significantly lower in ABV than in TDF treated patients. Urine concentrations of α-GST showed a nonsignificant variation in both groups, while Cyc excretion was significantly higher at T1 and T3 in TDF-treated compared to ABV-treated patients. In conclusion, TDF may be associated with subclinical mitochondrial damage, inducing at a later stage increased urinary excretion of phosphate and uric acid, as markers of incipient tubular injury.

Abstract
We report a 46-year-old man who has sex with men (MSM) patient, of Scottish descent, who had no history of arterial hypertension, diabetes, or illicit drug use, was hepatitis C virus (HCV) negative but underwent right nephrectomy for urothelial tumor in 2006. Before starting antiretroviral therapy, he had a CD4 cell count of 316/mm(3) and plasma HIV RNA level was 1,020,537 copies per milliliter. He developed acute renal failure only 2 weeks after introduction of tenofovir-based antiretroviral therapy and then required 3 months of hemodialysis. After the end of hemodialysis, antiviral therapy was resumed with abacavir (300 mg×2/day), lamivudine (300 mg every day), and lopinavir/ritonavir (400/100 mg twice daily). Renal biopsy revealed severe and diffuse toxic acute tubular necrosis Two years after tenofovir discontinuation, the patient's renal function remained subnormal. Although severe renal toxicity due to tenofovir is rare, patients receiving tenofovir must be monitored closely for renal dysfunction especially during the first weeks of tenofovir therapy.

Abstract
Tenofovir is an acyclic nucleotide analogue reverse-transcriptase inhibitor structurally similar to the nephrotoxic drugs adefovir and cidofovir. Tenofovir is widely used to treat HIV infection and approved for treatment of hepatitis B virus. Despite initial cell culture and clinical trials results supporting the renal safety of tenofovir, its clinical use is associated with a low, albeit significant, risk of kidney injury. Proximal tubular cell secretion of tenofovir explains the accumulation of the drug in these mitochondria-rich cells. Tenofovir nephrotoxicity is characterized by proximal tubular cell dysfunction that may be associated with acute kidney injury or chronic kidney disease. Withdrawal of the drug leads to improvement of analytical parameters that may be partial. Understanding the risk factors for nephrotoxicity and regular monitoring of proximal tubular dysfunction and serum creatinine in high-risk patients is required to minimize nephrotoxicity. Newer, structurally similar molecular derivatives that do not accumulate in proximal tubules are under study.

Abstract
Coinfection with hepatitis C (HCV) significantly increases the risk of acute and chronic renal disease in HIV-infected individuals. However, the burden of acute kidney injury (AKI) directly attributable to HIV among HCV-infected individuals and associated risk factors are not well understood. Within a prospective cohort, AKI episodes were identified by a rise in creatinine of 0.5 mg/dL. Incidence of first AKI events was calculated for HIV/HCV coinfected versus HCV monoinfected subjects, and multivariable analyses using Cox proportional hazards were performed to identify predictors of AKI. Throughout the study period, 35% HIV/HCV coinfected and 17% HCV monoinfected subjects developed AKI, with incidence of 8.74/100 person-years and 3.53/100 person-years, respectively (hazard ratio (HR) 2.48; [95% confidence interval (CI) 1.50, 3.74]). In multivariable analysis, HIV coinfection (HR 2.19 [1.33, 3.62]), decompensated cirrhosis (HR 6.64 [3.81, 11.6]), and cocaine use (HR 2.06 [1.15, 3.71]) were independently associated with AKI. HCV genotype, HCV viral load, hazardous drinking, and heroin use were not associated with AKI. Study limitations included potential misclassification bias of HCV-infected individuals as serial HIV antibody testing was not routinely performed after study entry, and inability to adjust for tenofovir use in multivariable analysis. In conclusion, among subjects with HCV infection, decompensated cirrhosis, HIV coinfection, and cocaine use are associated with increased risk of AKI. These findings highlight the importance of preventing and treating cirrhosis, controlling HIV coinfection, and reducing cocaine use in HIV/HCV coinfected persons.

Abstract
IMPORTANCE OF THE FIELD Tenofovir (TFV) is a nucleotide analogue widely used for the treatment of HIV infection. Despite its proven efficacy and safety, cases of kidney tubular dysfunction have increasingly been reported and concern exists about the risk of nephrotoxicity associated with the long-term use of TFV. AREAS COVERED IN THIS REVIEW Evidences about the renal toxicity associated with TFV use as well as predictors are examined. The most relevant publications assessing TFV safety and those which have reported cases of tubular dysfunction were identified and carefully revised. WHAT THE READER WILL GAIN Renal damage of clinical significance caused by TFV is uncommon in the short-mid-term. It occurs more frequently in subjects with underlying kidney conditions. TFV primarily results in kidney tubular dysfunction and less frequently in glomerular abnormalities. Kidney damage may progress over time under long-term TFV exposure but is reversible in most cases on drug discontinuation. TAKE HOME MESSAGE Severe renal damage associated with TFV use is uncommon and of multifactorial origin. However, mild tubular dysfunction is recognized in a substantial proportion of TFV-treated individuals and tends to increase with cumulative exposure.

Abstract
Although kidney disease has been a recognized complication of HIV infection since the beginning of the HIV epidemic, its epidemiology, underlying causes and treatment have evolved in developed countries where HAART has been widely available. HIV-associated nephropathy and HIV immune complex-mediated kidney disease were the prominent renal diagnoses in the earlier period of the HIV epidemic. While HIV immune complex-mediated kidney disease remains a common finding among HIV-infected individuals with kidney disease, the incidence of HIV-associated nephropathy has been diminishing in developed countries. The role of the metabolic effects of long-term HAART exposure and nephrotoxicity of certain antiretroviral medications on the development and progression of chronic kidney disease is now of increasing concern. The long-term clinical implications of acute kidney injury among HIV-infected persons are increasingly recognized. Kidney disease in HIV-infected persons continues to be a major risk factor for morbidity and mortality in this patient population; therefore, early recognition and treatment of kidney disease are imperative in lessening the impact of kidney disease on the health of HIV-infected individuals. This review focuses on recent developments and ongoing challenges in the understanding, diagnosis and management of HIV-related kidney disease.

Abstract
Renal dysfunction is an increasingly recognized non-AIDS-defining comorbidity among HIV-infected persons. The role of HIV-related factors in renal dysfunction remains unclear. We performed a cross-sectional study at two military clinics with open access to care to determine the impact of HIV factors, including antiretroviral therapy, on renal function. Renal dysfunction was defined as a glomerular filtration rate (GFR) < 60 mL/min/1.73 m(2). We evaluated 717 HIV patients with a median age of 41 years; 92% were male, 49% Caucasian, and 38% African American; median CD4 count was 515 cells/mm(3) and 73% were receiving highly active antiretroviral therapy (HAART). Twenty-two patients (3%) had renal dysfunction. Factors associated with renal dysfunction in the multivariate logistic analyses included older age (odds ratio [OR] 2.0 per 10 year increase, p = 0.006), lower CD4 nadir (OR 0.6 per 100 cell change, p = 0.02), and duration of tenofovir use (OR 1.5 per year use, p = 0.01). Among persons initiating tenofovir (n = 241), 50% experienced a reduction in GFR (median -10.5 mL/min/1.73 m(2), 95% CI, -8.9 to -13.3) within 2 years. Among tenofovir users, factors associated with a reduction in GFR included female gender (p < 0.001), African American ethnicity (p = 0.003), and lower CD4 nadir (p = 0.002). In summary, renal dysfunction was relatively uncommon among our HIV-infected patients, perhaps due to their young age, lack of comorbidities, or as a result of our definition that did not include proteinuria. Renal dysfunction was associated with duration of tenofovir use. Factors associated with renal loss among tenofovir users included female gender, African American ethnicity, and CD4 nadir <200 cells/mm(3). Consideration for more frequent monitoring of kidney function among these select HIV patients may be warranted.
