Prevalence of renal dysfunction among HIV infected patients receiving Tenofovir at Mulago: a cross-sectional study.

ABSTRACT:

Background

There is an increasing burden of non-communicable disease globally. Tenofovir disoproxil fumarate (TDF) is the most commonly prescribed antiretroviral drug globally. Studies show that patients receiving TDF are more prone to renal dysfunction at some point in time during treatment. Evaluation of kidney function is not routinely done in most HIV public clinics. Identification of renal dysfunction is key in resource constrained settings because managing patients with end stage renal disease is costly.

Method

This was a cross-sectional study conducted at an outpatient clinic in 2018 involving patients on TDF for at least 6?months who were 18?years or older. Patients with documented kidney disease and pregnancy were excluded. Estimated glomerular filtration rate (eGFR) was calculated using the CKD-Epi formula. Renal dysfunction was defined as any of the following; either eGFR2,or proteinuria of ?2⁺ on urine dipstick, glycosuria with normal blood glucose. Electrolyte abnormalities were also documented.

Results

We enrolled 278 participants. One hundred sixty nine (60.8%) were females, majority 234(84.2%) were?ConclusionsThe prevalence of renal dysfunction was low though some participants had hypocalcaemia. Screening for kidney disease should be done in symptomatic HIV infected patients on TDF.

Project description:BACKGROUND:HIV infection affects multiple organs and the kidney is a common target making renal disease, one of the recognized complications. Microalbuminuria represents an early, important marker of kidney damage in several populations including HIV-infected antiretroviral therapy (ART) naïve patients. Early detection of microalbuminuria is critical to slowing down progression to chronic kidney disease (CKD) in HIV-infected patients, however, the burden of microalbuminuria in HIV-infected antiretroviral therapy (ART) naïve patients in Uganda is unclear. METHODS:A cross-sectional study was conducted in the Mulago Immune suppression syndrome (ISS) clinic among adult HIV?-?infected ART naïve outpatients. Data on patient demographics, medical history was collected. Physical examination was performed to assess body mass index (BMI) and hypertension. A single spot morning urine sample from each participant was analysed for microalbuminuria using spectrophotometry and colorimetry. Microalbuminuria was defined by a urine albumin creatinine ratio (UACR) 30-299?mg/g and macroalbuminuria by a UACR >?300?mg/g. To assess the factors associated with microalbuminuria, chi-square, Fisher's exact test, quantile regression and logistic regression were used. RESULTS:A total of 185 adult participants were consecutively enrolled with median age and CD4+ counts of 33(IQR?=?28-40) years and 428 (IQR?=?145-689) cells/?L respectively. The prevalence of microalbuminuria was 18.9% (95% CI, 14-25%). None of the participants had macroalbuminuria. CD4+ count <350cells/?L was associated with increased risk of microalbuminuria (OR: 0.27, 95% CI: 0.12-0.59), P value?=?0.001). Diabetes mellitus, hypertension, smoking, alcohol intake were not found to be significantly associated with microalbuminuria. CONCLUSION:Microalbuminuria was highly prevalent in adult HIV?-?infected ART naive patients especially those with low CD4+ count. There is need to study the effect of ART on microalbuminuria in adult HIV?-?infected patients.

Project description:BackgroundData on the prevalence of renal and urine abnormalities among HIV-infected children in Sub-Saharan Africa are limited. We set out to determine the prevalence of proteinuria; low estimated glomerular filtration rate (eGFR), urinary tract infection and associated factors among HIV-infected antiretroviral therapy (ART) naive children, aged 2-12 years, attending the paediatric HIV clinic at a tertiary hospital in Harare.MethodsConsecutive ART naive children attending the clinic between June and October 2009 were recruited. Detailed medical history was obtained and a complete physical examination was performed. Children were screened for urinary tract infection and for significant persistent proteinuria. Serum creatinine was used to estimate GFR using the modified Counahan-Barratt formula. The Student's t-test was used to analyse continuous variables and the chi-square or Fisher's exact test was used to analyse categorical data. Logistic regression was performed to assess the relationship between study factors and urine abnormalities, persistent proteinuria and the eGFR.ResultsTwo hundred and twenty children were enrolled into the study. The median age was 90 months (Q1=65.5; Q3=116.5). The prevalence of urinary tract infection was 9.5%. Escherichia coli was the predominant organism. There was uniform resistance to cotrimoxazole. Persistent proteinuria (urine protein to creatinine ratio greater than 0.2, a week apart) was found in 5% of the children. Seventy-five children (34.6%) had mild to moderate renal impairment shown by a low eGFR (30 to <90 ml/min/1.73 m2). Persistent proteinuria was more likely to be found in children who were wasted, weight-for-height (WHZ) z-score <-2 (p=0.0005). Children with WHO clinical stage 4 were more likely to have a low eGFR than children with less advanced stages (OR 2.68; CI 1.24-5.80). Urine abnormalities were more likely to be observed in children with WHO clinical stages 3 and 4 (OR 2.20; CI 1.06-4.60).ConclusionThere is significant renal impairment among HIV-infected, ART naive children aged 2-12 years attending the outpatient paediatric HIV clinic at Harare Central Hospital. The abnormalities are more likely to occur in children with advanced HIV/AIDS. Screening for renal impairment and urinary tract infections in HIV-infected children before initiation of ART and regularly thereafter would be helpful in their management.KeywordsHIV, renal disease, persistent proteinuria, glomerular filtration rate, urinary tract infection.

Project description:BackgroundTreatment with tenofovir is sometimes associated with renal dysfunction. Limited information is available on this side effect in patients with small body weight, although the use of tenofovir will spread rapidly in Asia and Africa, where patients are likely to be of smaller body weight.MethodsIn a single-center cohort, Japanese patients with HIV infection who started tenofovir-containing antiretroviral therapy were retrospectively analyzed. The incidence of tenofovir-associated renal dysfunction, defined as more than 25% decrement of estimated glomerular filtration rate (eGFR) from the baseline, was determined. The effects of small body weight and body mass index (BMI) on tenofovir-associated renal dysfunction, respectively, were estimated in univariate and multivariate Cox hazards models as the primary exposure. Other possible risk factors were evaluated by univariate analysis and those found significant were entered into the multivariate analysis.ResultsThe median weight of 495 patients was 63 kg. Tenofovir-related renal dysfunction occurred in 97 (19.6%) patients (incidence: 10.5 per 100 person-years). Univariate analysis showed that the incidence of tenofovir-related renal dysfunction was significantly associated with smaller body weight and BMI, respectively (per 5 kg decrement, HR?=?1.23; 95% CI, 1.10-1.37; p<0.001)(per 1 kg/m(2) decrement, HR?=?1.14; 95% CI, 1.05-1.23; p?=?0.001). Old age, high baseline eGFR, low serum creatinine, low CD4 count, high HIV viral load, concurrent nephrotoxic drugs, hepatitis C infection, and current smoking were also associated with tenofovir-related renal dysfunction. Multivariate analysis identified small body weight as a significant risk (adjusted HR?=?1.13; 95% CI, 1.01-1.27; p?=?0.039), while small BMI had marginal significance (adjusted HR?=?1.07; 95% CI 1.00-1.16; p?=?0.058).ConclusionThe incidence of tenofovir-associated renal dysfunction in Japanese patients was high. Small body weight was identified as an independent risk factor for tenofovir-associated renal dysfunction. Close monitoring of renal function is advocated for patients with small body weight treated with tenofovir.

Project description:This study assesses malaria prevention and treatment behaviour among people living with HIV/AIDS (PLWHA) in Owerri, South Eastern Nigeria. Although Nigeria bears one of the world's largest burdens of both malaria and HIV, there is almost no research studying how co-infected patients manage their care. We systematically sampled 398 PLWHA receiving care at Imo State Specialist Hospital and the Federal Medical Centre in Owerri to complete a structured, pre-tested questionnaire on malaria care-seeking behaviour. Descriptive statistics were reported and chi-square tests and multivariate logistic regressions were also used. The majority of HIV-infected patients (78.9%) reported having had an episode of suspected malaria quarterly or more often. There was a large variation in care-seeking patterns: on suspicion of malaria, 29.1% of participants engaged in self-medication; 39.2% went to drug shops, and only 22.6% visited HIV/AIDS care centres. Almost 40% waited more than 24 hours before initiating treatment. Most (60.3%), reported taking recommended artemisinin-based combination treatments (ACT) but a significant minority took only paracetamol (25.6%) or herbal remedies (3.5%). Most (80%) finished their chosen course of treatment; and completion of treatment was significantly associated with the frequency of suspected malaria occurrence (p = 0.03). Most (62.8%) did not take anti-malaria medication while taking antiretroviral treatment (ART) and almost all (87.6%) reported taking an ACT regimen that could potentially interact with Nigeria's first-line ART regimen. Our findings suggest the need to pay more attention to malaria prevention and control as a crucial element in HIV/AIDS management in this part of Nigeria and other areas where malaria and HIV/AIDS are co-endemic. Also, more research on ART-ACT interactions, better outreach to community-level drug shops and other private sector stakeholders, and clearer guidelines for clinicians and patients on preventing and managing co-infection may be needed. This will require improved collaboration between programmes for both diseases.

Project description:BackgroundAlthough the burden of impaired renal function is rising in sub-Saharan Africa (SSA), little is known about correlates of impaired renal function in the region. We determined factors associated with estimated glomerular filtration rate (eGFR) and impaired renal function in HIV-infected and HIV-uninfected adults.MethodsWe undertook cross-sectional analysis of data from 1947 adults at enrolment for a cohort study on diabetes and associated complications in HIV patients in Mwanza, north-western Tanzania. A structured questionnaire was used to collect data on sociodemography, smoking, alcohol, physical activity, antiretroviral therapy (ART) and anthropometry. We measured blood pressure, tested blood samples for creatinine, glucose and HIV, and performed Kato Katz for Schistosoma mansoni. Correlates of eGFR (mL/min/1.73 m2) and impaired renal function (eGFR< 60 mL/min/1.73 m2) were determined using linear regression and logistic regression, respectively.Results655 (34%) participants were HIV-uninfected, 956 (49%) were ART-naive HIV-infected and 336 (17%) were HIV-infected adults on ART. The mean age was 41 years (SD12) and majority (59%) were females. Overall, the mean eGFR was 113.6 mL/min/1.73 m2 but 111.2 mL/min/1.73 m2 in HIV-uninfected, 109.7 mL/min/1.73 m2 in ART-naive HIV-infected and 129.5 mL/min/1.73 m2 in HIV-infected ART-experienced adults, and respective prevalence of impaired renal function was 7.0, 5.7, 8.1 and 6.3%. Correlates of lower eGFR were increasing age, higher socioeconomic status, unhealthy alcohol drinking, higher body mass index and diabetes mellitus. Anaemia was associated with 1.9 (95% Confidence Interval (CI):1.2, 2.7, p = 0.001) higher odds of impaired renal function compared to no anaemia and this effect was modified by HIV status (p value 0.02 for interaction).ConclusionImpaired renal function is prevalent in this middle-aged study population. Interventions for prevention of impaired renal function are needed in the study population with special focus in HIV-infected adults and those with high socioeconomic status. Interventions targeting modifiable risk factors such as alcohol and weight reduction are warranted.
