Abstract
Background People with HIV are at a greater risk of end-stage kidney disease than the general population. Considering the risk of death after end-stage kidney disease, access to renal transplantation in people with HIV is critically important. Methods We included all adult patients on chronic dialysis in Ontario, Canada, between 1 April 2007 and 31 December 2020. We determined the probability of kidney transplantation with competing risk of death over time since the initiation of dialysis by calculating the adjusted subdistribution hazard ratios (sdHR; 95% confidence interval [CI]). We also compared long-term renal allograft and posttransplant mortality outcomes between HIV-negative and HIV-positive persons. Results Of 40 686 people (median age, 68 years; interquartile range, 57-77; 38.4% women), 173 were HIV-positive and 40 513 were HIV-negative. The incidence of kidney transplantation in HIV-negative and HIV-positive patients was 40.5 (95% CI, 39.4-41.6)/1000 person-years and 35.0 (95% CI, 22.8-53.7)/1000 person-years, respectively (P = .51). Considering the competing risk of death, HIV-positive people had a significantly lower chance of receiving kidney transplants than HIV-negative people (sdHR, 0.46 [95% CI, .30-.70]). The long-term allograft failure risk was not significantly different between HIV-negative and HIV-positive people, considering the competing risk of posttransplant death (sdHR, 1.71 [95% CI, .46-6.35]). Conclusions Although the incidence and crude probability of kidney transplantation were similar among HIV-negative and HIV-positive persons in this cohort, those with HIV had a significantly lower likelihood of kidney transplantation than those without HIV. Having HIV was not significantly associated with a poor long-term allograft outcome compared with patients without HIV.

Abstract
There is an increasing global burden of diabetes mellitus (DM) and chronic kidney disease (CKD), coupled with a high burden of people with HIV (PWH). Due to an increased lifespan on ART, PWH are now at risk of developing non-communicable diseases, including DM. Africa has the greatest burden of HIV infection and will experience the greatest increase in prevalence of DM over the next two decades. In addition, there is a rising number of people with CKD and progression to kidney failure. Therefore, there is an urgent need for the early identification and management of all 3 diseases to prevent disease progression and complications. This is particularly important in Africa for people with CKD where there is restricted or no access to dialysis and/or transplantation. This review focuses on the epidemiology and pathophysiology of the interaction between HIV infection and DM and the impact that these diseases have on the development and progression of CKD. Finally, it also aims to review the data on the management, which stems from the growing burden of all three diseases.

Abstract
Background HIV is a risk factor for the development of chronic kidney disease. People with chronic kidney disease in the state sector are likely to be prescribed continuous ambulatory peritoneal dialysis (CAPD). Previous studies have raised concern about the safety of CAPD in people living with HIV (PLWH) compared to HIV-negative patients. Objectives To compare the risk of peritonitis, and modality and patient survival by HIV status in patients receiving CAPD at Helen Joseph Hospital. Method A retrospective study of patients receiving CAPD between 01 January 2007 and 31 December 2017 was undertaken. Five-year patient and modality survival were modelled for PLWH and HIV-negative subgroups and analysed using the log-rank test; the effect of CD4 count, HIV viral load, and duration of antiretroviral therapy on these parameters in PLWH were additionally modelled using the Cox Proportional Hazards technique. Results Eighty-four patients, comprising of 21 PLWH and 63 HIV-negative patients, were analysed. No difference was observed in the proportion of patients who had at least one episode of peritonitis between PLWH (61.2%) and HIV-negative patients (63.5%) (P = 0.547). A trend towards increased risk of peritonitis due to Gram-negative organisms in PLWH was noted (odds ratio: 3.20, 95% confidence interval: 0.86-11.9, P = 0.083). No difference was observed in 5-year patient or modality survival on CAPD between PLWH (log-rank P = 0.161) and HIV-negative patients (log-rank P = 0.240). Conclusion People living with HIV should not be excluded from CAPD as a mode of kidney replacement therapy (KRT).

Abstract
Clinical management and optimal treatment are essential to improving outcomes for people living with HIV (PLWH). We assessed trends and outcomes of chronic kidney disease (CKD) in PLWH in a resource-limited center of central China. All PLWH who were followed up in a tertiary referral center in Wuhan, China, from July 2016 to June 2021 were evaluated. CKD was defined as glomerular filtration rate (GFR) <60 mL/min/1.73 m2 during two consecutive measurements 3 months apart. Baseline characteristics of the participants were extracted from the hospital medical records. The prevalence rate and associated risk factors of CKD were analyzed. A total of 863 PLWH with normal kidney function at baseline were analyzed. The median age was 33 (interquartile ranges: 26-49) years, and 778 (90.2%) were male and 85 (9.8%) were female. Among them, 50 (5.8%) had their GFR falling below 60 mL/min/1.73 m2 after a median of 54 months. Adjusted multivariate logistic regression revealed older age [adjusted odds ratio (aOR) = 1.04, 95% confidence interval (95% CI): 1.01-1.07], female sex (aOR = 3.17, 95% CI: 1.14-8.84), lower body weight (aOR = 0.95, 95% CI: 0.91-1.00), lower hemoglobin (aOR = 3.54, 95% CI: 1.51-8.30), longer duration of antiretroviral therapy exposure (aOR = 1.02, 95% CI: 1.00-1.04), and a baseline GFR between 60 and 90 mL/min/1.73 m2 (aOR = 3.89, 95% CI: 1.21-12.46) were associated with the development of CKD. Our findings showed that CKD is not infrequent in PLWH with a combination of traditional and HIV-specific risk factors for kidney disease, highlighting the suboptimal monitoring and treatment options of CKD in PLWH in resource-limited settings. Scalable monitoring strategy to improve care for this population is warranted.

Abstract
INTRODUCTION End-stage renal disease is a significant cause of morbidity and mortality in persons with HIV (PWH). Limited data exist on access to kidney transplantation for this population. METHODS A dataset inclusive of incident dialysis patients between 2012 and 2016 with follow-up through December 2017 that identifies PWH and the general dialysis population of Network 6 (Georgia, North Carolina, South Carolina) was created through merging the United States Renal Data System with the southeastern early transplant access registry. Early steps to kidney transplantation and patient and dialysis facility-level characteristics that serve as barriers to transplantation were described. RESULTS Twenty-three thousand four hundred fourteen patients were identified; 469 were PWH. Compared to non-HIV individuals, PWH were younger (49 vs. 58 years, p < 0.001), predominantly Black (87% vs. 56% p < 0.001) and male (72% vs. 56% p < 0.001). PWH were less likely to be referred to kidney transplant within 1 year of starting dialysis (36% vs. 41% p < 0.001) and waitlisted within 1 year of evaluation-start (14% vs. 30%, p = 0.05). PWH (vs. non-PWH) waited longer for referral, evaluation-start, and waitlisting and in multivariable analysis; HIV positivity was associated with a lower probability of referral (hazard ratios [HR]: 0.70; 95% confidence intervals [CIs]: 0.62-0.80), evaluation (HR 0.66; 95% CI: 0.55-0.80), and waitlisting (HR 0.29; 95% CI: 0.20-0.41). CONCLUSIONS Targeted interventions are needed to improve access to kidney transplants, particularly in waitlisting, for PWH.

Abstract
INTRODUCTION Since the developmentof combined antiretroviral therapy (cART), HIV-associated mortality and the incidence of HIV-associated end-stage kidney disease (ESKD) has decreased. However, in the United States, an increase in non-HIV-associated kidney diseases within the HIV-positive population is expected. AREAS COVERED In this review, the authors highlight the risk factors for kidney disease within an HIV-positive population and provide the current recommendations for risk stratification and for the monitoring of its progression to chronic kidney disease (CKD), as well as, treatment. The article is based on literature searches using PubMed, Medline and SCOPUS. EXPERT OPINION The authors recommend clinicians (1) be aware of early cART initiation to prevent and treat HIV-associated kidney diseases, (2) be aware of cART side effects and discriminate those that may become more nephrotoxic than others and require dose-adjustment in the setting of eGFR ≤ 30ml/min/1.73m2, (3) follow KDIGO guidelines regarding screening and monitoring for CKD with a multidisciplinary team of health professionals, (4) manage other co-infections and comorbidities, (5) consider changing cART if drug induced toxicity is established with apparent eGFR decline of ≥ 10ml/min/1.73m2 or rising creatinine (≥0.5mg/dl) during drug-drug interactions, and (6) strongly consider kidney transplant in appropriately selected individuals with end stage kidney failure.

Abstract
Individuals with HIV are at increased risk for ESKD. Kidney transplantation is the best treatment for ESKD in the HIV+ population. Despite reduced access to transplantation, patients who are HIV+ have excellent outcomes and clearly benefit from receiving one. Common post-transplant complications and management concerns, including the optimal antiretroviral regimen, immunosuppression protocols, infectious prophylaxis, hepatitis C coinfection, metabolic complications, and malignancy are all discussed.

Abstract
Chronic kidney disease (CKD) is a comorbidity of major clinical significance amongst people living with HIV (PLWHIV) and is associated with significant morbidity and mortality. The prevalence of CKD is rising, despite the widespread use of antiretroviral therapy (ART) and is increasingly related to prevalent non-infectious comorbidities (NICMs) and antiretroviral toxicity. There are great disparities evident, with the highest prevalence of CKD among PLWHIV seen in the African continent. The aetiology of kidney disease amongst PLWHIV includes HIV-related diseases, such as classic HIV-associated nephropathy or immune complex disease, CKD related to NICMs and CKD from antiretroviral toxicity. CKD, once established, is often relentlessly progressive and can lead to end-stage renal disease (ESRD). Identifying patients with risk factors for CKD, and appropriate screening for the early detection of CKD are vital to improve patient outcomes. Adherence to screening guidelines is variable, and often poor. The progression of CKD may be slowed with certain clinical interventions; however, data derived from studies involving PLWHIV with CKD are sparse and this represent an important area for future research. The control of blood pressure using angiotensin converting enzyme inhibitors and angiotensin receptor blockers, in particular, in the setting of proteinuria, likely slows the progression of CKD among PLWHIV. The cohort of PLWHIV is facing new challenges in regards to polypharmacy, drug-drug interactions and adverse drug reactions. The potential nephrotoxicity of ART is important, particularly as cumulative ART exposure increases as the cohort of PLWHIV ages. The number of PLWHIV with ESRD is increasing. PLWHIV should not be denied access to renal replacement therapy, either dialysis or kidney transplantation, based on their HIV status. Kidney transplantation amongst PLWHIV is successful and associated with an improved prognosis compared to remaining on dialysis. As the cohort of PLWHIV ages, comorbidity increases and CKD becomes more prevalent; models of care need to evolve to meet the new and changing chronic healthcare needs of these patients.

Abstract
Prior to the advent of combined antiretroviral therapy (cART), human immunodeficiency virus-associated nephropathy (HIVAN) was inevitably associated with rapidly progressive renal failure and dialysis dependence. HIV-1 seropositive patients often met with untimely deaths due to complications of end-stage renal disease (ESRD), opportunistic infections, or other HIV-related end-organ failure. Although the association between cART and improved outcomes in HIVAN has been recognized for over 20 years, no randomized trials have specifically examined this effect to date. In terms of reversal of dialysis-dependent renal failure after cART initiation, only a handful of case reports exist. The authors report a case of a 44-year-old Latino male requiring thrice-weekly haemodialysis in the setting of biopsy-proven HIVAN who was able to stop dialysis in 7 months after being initiated on cART.

Abstract
BACKGROUND HIV-positive kidney transplant (KT) recipients have similar outcomes to HIV-negative recipients. However, HIV-positive patients with advanced kidney disease might face additional barriers to initiating the KT evaluation process. We sought to characterize comorbidities, viral control and management, viral resistance, and KT evaluation appointment rates in a cohort of KT evaluation-eligible HIV-positive patients. METHODS We included patients seen between January 1, 2008, and December 31, 2015, at a primary care HIV clinic who met KT evaluation eligibility by an estimated glomerular filtration rate ≤20 mL/min/1.73 meters2 or dialysis dependence. The primary outcome was a documented appointment for KT evaluation. RESULTS Of 3735 patients evaluated at the HIV primary clinic during the study period, 42 (1.6%) were KT evaluation-eligible patients. The median age was 47 years, 77% were male, and 95%, black. Median CD4 count was 328 cells/mm3 (IQR 175-461). Among the 63% percent with antiretroviral therapy (ART) prescription, 40% had viral loads >200 copies. Among patients with HIV resistance profiles (50%, n = 21), 52% had resistance to at least one class of ART. A majority (60%, n = 25) were scheduled for KT evaluation appointment, but of those, only 8% (n = 2) had evidence of appointments before dialysis dependence. Those without appointments had more schizophrenia (29% vs 4%, P = .02), resistance (78% vs 33%, P = .04), ART prescription (76% vs 48%, P = .04), and more kidney disease of unknown etiology (53% vs 8%, P = .02). CONCLUSION Kidney transplant evaluation-eligible HIV-positive patients had a high rate of evaluation appointments, but a low rate of preemptive evaluation appointments. Schizophrenia and viral resistance disproportionally affected patients without evaluation appointments. These data precede the recommendation for universal ART for all HIV+ patients, regardless of CD4 count and viral load, and must be interpreted in the context of this limitation.

Abstract
The kidney is an important target organ in human immunodeficiency virus (HIV) infection, and a variety of renal disorders could occur throughout the course of the disease. HIV- associated nephropathy (HIVAN) is the most common form of kidney disease resulting directly from HIV infection. The true prevalence of HIVAN among infected African children is unknown largely due to lack of surveillance and reporting. We thus aimed to determine the prevalence of HIVAN and associated factors among HIV-infected children at the University of Maiduguri Teaching Hospital. This was a cross-sectional study carried out at the Pediatric Infectious Clinic. Children aged ≤15 years were recruited through systematic random sampling. Relevant sociodemographic and clinical information were obtained. Spot urine sample was analyzed using a multistix (Combi-Screen 10SL Analyticon Biotechnologies AG, Germany), and proteinuria of ≥2+ was considered significant. The CD4+ count and CD4+% (for those <5 years) were obtained using a PARTEC™ CD4+ easy count kit. The obtained data were entered and analyzed using Statistical Package for the Social Sciences version 16.0. A total of 250 children were recruited. Eighty-five (34%) of them had HIVAN. Sex, social class, and mode of transmission were not significantly associated with HIVAN (P >0.05). However, age, medication status (highly active antiretroviral therapy [HAART]), duration on HAART, and disease severity (both clinical and immunological) all had a significant association to HIVAN (p = 0.005, 0.004, 0.008, and <0.001, respectively). These factors also showed a positive but weak correlation to HIVAN; while age had the least correlation coefficient (0.157), immunological class had the highest r = 0.458. However, these relationships were all significant (P <0.5). HIVAN is highly prevalent among children living with HIV in Maiduguri. Routine screening through urina-lysis and early commencement of HAART is recommended.

Abstract
BACKGROUND Chronic kidney disease (CKD) is one of the major complications of Human immune deficiency Virus (HIV) and a risk factor for poor outcome of these patients. We aimed to describe the profile and outcome of HIV positive patients with CKD in Douala general hospital in Cameroon. METHODS HIV positive patients with CKD referred to the nephrologist from January 2007 to March 2013 were included. Socio demographic, clinical (history and stage of HIV, comorbidities, baseline nephropathy, used of c-ART), para clinical data at referral (serum urea, creatinine, full blood count, CD4 count, serum calcium, phosphorus, albumin), dialysis initiation and outcome at 1 year were collected from medical records. GFR was estimated using Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations. CKD was defined and classified according to the Kidney Disease Improving Global Outcomes (KDIGO 2012). RESULTS We included 156 patients (51.3% men) with a mean age of 45.4 ± 12.1 years. Hypertension (36.5%), diabetes (17.9%) and Hepatitis C (7.7%) were the main comorbidities. HIV associated nephropathy (27.6%), chronic glomerulonephritis (15.4%) diabetes (14.1%) and hypertension (13.5%) were the leading causes of kidney disease. Before referral HIV status was known by 109 (69.9%) patients, with 76 (69.7%) being on c-ART. Median CD4 count was 241 (117-438) cells/mm3. Prevalence of anemia (93.9%), hypocalcemia (68.6%) and Proteinuria (77.6%) was high, 94 (60.3%) patients were at CKD stage 5 at referral and 37 (23.7%) underwent emergency dialysis. After 1 year, 64 (41.0%) patients were lost to follow up. The mortality rate was 49% and 25 (28.7%) were maintenance hemodialysis, and being on c-ART was associated with a lower risk of death (HR: 0.45; 95% CI: 0.23-0.89; p = 0.021). CONCLUSION HIV patients with CKD were referred late with high morbidity and need for urgent hemodialysis. HIVAN was the main etiology of CKD and mortality rate was high mainly due to the absence of c-ART at referral.

Predictors of chronic kidney disease among HIV-infected patients on highly active antiretroviral therapy at the University of Calabar Teaching Hospital, Calabar, South-South Nigeria. HIV AIDS-RESEARCH AND PALLIATIVE CARE 2019; 11:61-67. [PMID: 31118824 PMCID: PMC6501420 DOI: 10.2147/hiv.s189802] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/05/2018] [Accepted: 02/18/2019] [Indexed: 12/17/2022]
Abstract
Background: The burden of the people living with human immunodeficiency virus (HIV) infection and the acquired immunodeficiency syndrome (AIDS) is largely borne by communities in Sub-Saharan Africa. The rate of kidney disease is increasing amongst HIV patients and occurs more often in patients with advanced stage of the disease with lower CD4 counts and associated with a high rate of morbidity and mortality. The objective of this study is to determine the prevalence and predictors of chronic kidney disease (CKD) amongst HIV patients on highly active antiretroviral therapy (HAART) at the University of Calabar Teaching Hospital, Calabar. Materials and methods: This was a cross-sectional study that was carried out over a 4-month period from May to August 2018. In all, a total of 118 patients with HIV on HAART were recruited into the study in a consecutive manner and their serum creatinine measured with the calculation of estimated glomerular filtration rate (eGFR). Other data collected were sex, age, weight, height, body mass index (BMI), waist hip ratio (WHR), packed cell volume, CD4 count etcetera. Data collected were inputted and analyzed with SPSS version 18, and statistical significance was taken to be p<0.05. Results: There were more females (69.5%) amongst the HIV participants and the prevalence of CKD was 15.3%. The risk factors seen to be associated with CKD were lower levels of CD4 count below 200 cells/µl, lower PCV, weight, BMI, and eGFR. Also, higher levels of WHR and creatinine were associated with CKD. Factors directly correlated with CKD were weight, BMI and CD4 count levels, while creatinine level was inversely correlated with CKD. However, a logistic regression model showed only creatinine to be a predictor of CKD. Conclusion: HIV patients on antiretroviral therapy, mainly the highly active antiretroviral therapy (HAART) have a relatively high prevalence of CKD of 15.3% and high level of serum creatinine was predictive of CKD in the logistic regression model in our study.

Abstract
Background: Hemodialysis (HD) is one of the treatments provided to end-stage renal disease (ESRD) patients. A few studies have investigated the survival rate of HD patients in Iran. Hence, we decided to investigate the survival rate and it is predictors among Iranian ESRD patients. Methods: This is a retrospective cohort study conducted in 165 HD patients in Tuyserkan city (Hamadan province) during 20 years from 1996 to 2015. The checklist used to gather information was comprised of patients’ demographic and clinical information. The analysis was performed using Kaplan–Meier curves, log-rank test, and cox regression model. Results: The most prevalent cause of ESRD was reported to be high blood pressure (32.7%). The probability of survival rate at the end of 1st, 5th, and 10th year was 0.65, 0.16, and 0.05, respectively. Results of multivariate cox regression showed that old age, catheter vascular access, and high hemoglobin level have a negative significant effect on survival of HD patients (P < 0.05). Conclusions: Overall, the survival of HD patients seems to be low in Tuyserkan as compared to other studies. Age, ESRD cause, vascular access, marital status, and hemoglobin level among other factors are proved to have a significant effect on survival probability.

Abstract
HIV infection is a major public health problem worldwide. Due to shared modes of acquisition, many HIV+ patients are coinfected with Hepatitis C. HIV/HCV coinfected patients have an increased burden of chronic kidney disease and are more likely to progress to end-stage renal disease. Dialysis survival is diminished in the coinfected population, even in the contemporary era. Kidney transplantation offers a survival benefit over remaining on dialysis; however, posttransplant outcomes are inferior compared to patients with HIV infection alone. Direct acting antiviral agents may offer an opportunity to improve patient survival, but there are significant drug-drug interactions involving the direct acting antiviral agents, antiretroviral therapy, and immunosuppression that the clinician should be aware of.

Abstract
BACKGROUND Kidney transplantation (KTxp) provides dialysis independence, improved quality of life, and prolonged life expectancy for patients with end-stage renal disease. Before and during the early antiretroviral therapy era, KTxp was not a consideration for patients with end-stage renal disease who were HIV-positive (HIV+ve) given their short life expectancy and prevailing organ procurement constraints. Recent advancements in antiretroviral therapy and HIV care have overhauled this paradigm and KTxp has now been performed for several years, however, pragmatic studies documenting outcomes are lacking. We herein document the effectiveness of KTxp in patients who are HIV+ve by reporting clinical and health care utilization outcomes in the United States. METHODS Utilizing the Inpatient Databases of the Healthcare Cost & Utilization Project spanning 2008-2013, we identified all adult recipients of KTxp by procedural codes and recipients who are HIV+ve by ICD-9 codes. We extracted demographic, clinical, and resource utilization variables and compared recipients who are HIV+ve with those who are HIV-negative (HIV-ve). We then performed descriptive statistics and multivariate analysis using logistic regression to assess the effect of HIV on clinical and utilization outcomes. RESULTS A total of 104,137 patients had kidney transplants during the study period. Of the total, 605 patients were HIV+ve. Infections rates were similar among patients who were HIV+ve and HIV-ve (odds ratio [OR] 1.18, confidence interval [CI] 0.58-2.40; P = .652). In-hospital mortality rates were also similar (OR 0.83, CI 0.18-3.69; P = .80). Hospital charges for patients who were HIV+ve were no different from patients who were HIV-ve ($195,099 ± 1074 vs $186,567 ± 9558; P = .38). CONCLUSION Clinical and fiscal outcomes are comparable among patients who are HIV+ve and HIV-ve during transplant hospitalization.

Abstract
Background There are conflicting reports on the impact of HIV in the era of combined antiretroviral (c-ART) on survival of patient with ESKD. We aimed to compare the one-year survival of HIV positive patients to that of their HIV negative counterparts with ESKD on maintenance haemodialysis in Cameroon. Methods This was a retrospective cohort study conducted in the haemodialysis units of the Douala and Yaoundé General Hospitals. All HIV positive patients treated by maintenance haemodialysis between January 2007 and March 2015 were included. A comparative group of HIV negative patients with ESKD were matched for age, sex, co morbidities, year of dialysis initiation and haemodialysis unit. Relevant data at the time of haemodialysis initiation and during the first year of haemodialysis was noted. Survival was analysed using the Kaplan Meier and Cox regression hazard ratio estimator. A p value < 0.05 was considered statistically significant. Results A total of 57 patients with HIV and 57 without HIV were included. Mean age was 46.25 ± 11.41 years, and 52.6% were females in both groups. HIV nephropathy (50.9%) was the main presumed aetiology of ESKD in the HIV group, while chronic glomerulonephritis (33.3%) and diabetes (21.1%) were the main aetiologies in the HIV negative group. At initiation of dialysis, the median CD4 count was 212 cell/mm3 (IQR; 138–455) and 77.2% were receiving c-ART. The proportion of patients who initiated dialysis with a temporary venous catheter was similar in both groups (p = 0.06). After one year on haemodialysis, survival rate was lower in the HIV positive group compared to the HIV negative group (61.4%/78.9%, HR: 2.05; 95% CI: 1.03–4.08; p = 0.042).Kaplan Meier survival curve was in direction of a lower survival in HIV positive group (p = 0.052). Conclusion The one year survival of HIV positive patients on maintenance haemodialysis in Cameroon seems to be lower compared to their HIV negative counterparts.

Abstract
PURPOSE OF REVIEW Review epidemiology, pathophysiology, and management of hypertension in the pediatric dialysis population. RECENT FINDINGS Interdialytic blood pressure measurement, especially with ambulatory blood pressure monitoring, is the gold standard to assess for hypertension. Tools to assess dry weight aid in achievement of euvolemia, the primary therapy for management of hypertension. Persistent hypertension should be treated with antihypertensive medications and potentially with native nephrectomies. Cardiovascular disease continues to be the primary cause of morbidity and mortality in the dialysis population with hypertension as an important modifiable factor. Achievement on dry weight and limiting both aggressiveness of interdialytic weight gain and ultrafiltration rate underlie the best approach. Tools to assess volume status beyond clinical assessment have shown promise in achieving euvolemia. When hypertension persists despite achievement of euvolemia, antihypertensive medications may be required and in some cases native nephrectomies. Future studies in children are needed to determine the best antihypertensive class and ideal rate of ultrafiltration on hemodialysis towards achievement of normotension and reduction of cardiovascular risk.

Abstract
HIV-positive individuals are at increased risk for kidney disease, including HIV-associated nephropathy, noncollapsing focal segmental glomerulosclerosis, immune-complex kidney disease, and comorbid kidney disease, as well as kidney injury resulting from prolonged exposure to antiretroviral therapy or from opportunistic infections. Clinical guidelines for kidney disease prevention and treatment in HIV-positive individuals are largely extrapolated from studies in the general population, and do not fully incorporate existing knowledge of the unique HIV-related pathways and genetic factors that contribute to the risk of kidney disease in this population. We convened an international panel of experts in nephrology, renal pathology, and infectious diseases to define the pathology of kidney disease in the setting of HIV infection; describe the role of genetics in the natural history, diagnosis, and treatment of kidney disease in HIV-positive individuals; characterize the renal risk-benefit of antiretroviral therapy for HIV treatment and prevention; and define best practices for the prevention and management of kidney disease in HIV-positive individuals.

Abstract
Individuals with HIV infection are at elevated risk of developing end-stage renal disease. However, their outcomes after starting chronic dialysis in the contemporary era of widespread antiretroviral therapy are not well described. Using detailed data from a national dialysis provider, we determined HIV status by administrative codes and antiretroviral medication prescriptions, with hepatitis C virus (HCV) co-infection status provided by routinely measured serology. The survival on dialysis among 5348 individuals in the HIV+ group and 1863 HIV+/HCV+ individuals to a HIV-/HCV- reference cohort was compared. Race significantly modified the effect of HIV and HIV/HCV infection on mortality. In a multivariable model, HIV infection was not associated with an increased risk of death among Caucasians (hazard ratio 1.03, 95% confidence interval 0.91-1.16) but HIV/HCV co-infection (1.48, 1.18-1.87) was. In the same model for non-Caucasians, both HIV infection (1.44, 1.37-1.52) and HIV/HCV co-infection (1.71, 1.60-1.84) were significantly associated with higher mortality. A secondary analysis using propensity scores yielded similar results. Median follow-up for the reference group was 645 days (interquartile range 230-1323), 772 days (276-1623) for the HIV+ group and 777 days (334-1665) for the co-infected group. Thus, in the contemporary era of widespread antiretroviral use, HIV infection remains associated with a significant reduction in dialysis survival for non-Caucasians while HIV/HCV co-infection is associated with impaired survival regardless of race or ethnicity. Hence, interventions to improve the care for these vulnerable populations are needed.

Abstract
HIV-infected persons who achieve undetectable viral loads on antiretroviral therapy currently have near-normal lifespans. Liver disease is a major cause of non-AIDS-related deaths, and as a result of longer survival, the prevalence of end-stage renal disease in HIV is increasing. HIV-infected persons undergoing organ transplantation generally achieve comparable patient and graft survival rates compared to their HIV-uninfected counterparts, despite a nearly threefold increased risk of acute rejection. However, the ongoing shortage of suitable organs can limit transplantation as an option, and patients with HIV have higher waitlist mortality than others. One way to solve this problem would be to expand the donor pool to include HIV-infected individuals. The results of a South Africa study involving 27 HIV-to-HIV kidney transplants showed promise, with 3- and 5-year patient and graft survival rates similar to those of their HIV-uninfected counterparts. Similarly, individual cases of HIV-to-HIV liver transplantation from the United Kingdom and Switzerland have also shown good results. In the United States, HIV-to-HIV kidney and liver transplants are currently permitted only under a research protocol. Nevertheless, areas of ambiguity exist, including streamlining organ allocation practices, optimizing HIV-infected donor and recipient selection, managing donor-derived transmission of a resistant HIV strain, determining optimal immunosuppressive and antiretroviral regimens, and elucidating the incidence of rejection in HIV-to-HIV solid organ transplant recipients.

Abstract
BACKGROUND/AIMS The number of human immunodeficiency virus (HIV)-infected patients on hemodialysis (HD) have increased, and their prognostic factors are still poorly clarified. The study aimed to identify factors that can influence the survival of HIV-infected patients on HD. METHODS We performed a retrospective cohort study of 44 HIV-infected patients on HD. RESULTS A total of 17 patients (39%) died. Median survival on HD was 30.8 months and the survival rate at 1 and 5 years was 82.5 and 62.9%, respectively. Male (relative risk [RR] 3.1, p = 0.040) and blacks (RR 2.5, p = 0.037) had higher risk of death. The patients who died had a shorter duration of HIV infection (p = 0.028), had a higher viral load (p = 0.044), more opportunistic infections (p = 0.013), and a lower serum albumin (p = 0.009). Lower serum albumin, nonsexual HIV transmission, viral load, opportunistic infections, and usage of catheters were associated with lower survival. CONCLUSION Several demographic, viral, and dialysis variables may help to predict survival of this population. The intervention in these factors could improve their prognosis.

Abstract
BACKGROUND With the introduction of the Kidney Allocation System in the United States in December 2014, transplant centers can list eligible B blood type recipients for A2 organ offers. There have been no prior reports of ABO incompatible A2 to B deceased donor kidney transplantation in human immunodeficiency virus-positive (HIV+) recipients to guide clinicians on enrolling or performing A2 to B transplantations in HIV+ candidates. We are the first to report a case of A2 to B deceased donor kidney transplantation in an HIV+ recipient with good intermediate-term results. METHODS AND RESULTS We describe an HIV+ 39-year-old African American man with end-stage renal disease who underwent A2 to B blood type incompatible deceased donor kidney transplantation. Prior to transplantation, he had an undetectable HIV viral load. The patient was unsensitized, with his most recent anti-A titer data being 1:2 IgG and 1:32 IgG/IgM. Induction therapy of basiliximab and methylprednisolone was followed by a postoperative regimen of plasma exchange, intravenous immunoglobulin, and rituximab with maintenance on tacrolimus, mycophenolate mofetil, and prednisone. He had delayed graft function without rejection on allograft biopsy. Nadir serum creatinine was 2.0 mg/dL. He continued to have an undetectable viral load on the same antiretroviral therapy adjusted for renal function. CONCLUSIONS To our knowledge, this is the first report of A2 to B deceased donor kidney transplantation in an HIV+ recipient with good intermediate-term results, suggesting that A2 donor kidneys may be considered for transplantation into HIV+ B-blood type wait list candidates.

Abstract
BACKGROUND In Human immunodeficiency virus (HIV)-positive patients undergoing kidney transplantation, outcomes and immunosuppression (IS) protocol are not yet established due to infectious and neoplastic risks as well as to pharmacokinetic interactions with antiretroviral therapy (TARV). METHODS We report a retrospective, 1-center study on 18 HIV+ patients undergoing, between October 2007 and September 2015, kidney transplantation (13 cases) or combined kidney-liver transplant (5 cases). Inclusion criteria for transplant were based on the Italian National Transplant Center protocol. IS regimen was based on quick tapering of steroids and the use of mTOR inhibitors (mTORi) with low dose of calcineurin inhibitors (CNI). In the early post-transplant period, TARV was based on enfuvirtide, raltegravir, plus 1 or more nucleoside analogues. RESULTS In a mean follow-up of 3.1 years, patient survival rate at 1 and 3 years was, respectively, 86.6% and 84.6%, whereas graft survival was 81.2% and 78.6%. Cumulative rejection rate was 20.0% and 26.6% (1- and 3-year results). Median eGFR (MDRD) was 58.8 mL/min and 51.9 mL/min at 1 and 3 years. We had 9 cases of clinically relevant infections (2 Pneumocystis jirovecii pneumonia, 1 pulmonary aspergillosis, 2 severe sepsis, and 4 HCV reactivation) as well as 1 case (5.5%) of HIV reactivation. CONCLUSIONS IS therapy based on mTORi and low CNI dose ensures good graft survival, low rate of acute rejection, limited drug toxicity, and control of HIV disease. TARV has no significant interaction with IS therapy.

Abstract
Background Hemodialysis is the most common renal replacement therapy in patients with end stage renal disease (ESRD). Objectives The present study compared the performance of various parametric models in a survival analysis of hemodialysis patients. Methods This study consisted of 270 hemodialysis patients who were referred to Imam Khomeini and Fatima Zahra hospitals between November 2007 and November 2012. The Akaike information criterion (AIC) and residuals review were used to compare the performance of the parametric models. The computations were done using STATA Software, with significance accepted at a level of 0.05. Results The results of a multivariate analysis of the variables in the parametric models showed that the mean serum albumin and the clinic attended were the most important predictors in the survival of the hemodialysis patients (P < 0.05). Among the parametric models tested, the results indicated that the performance of the Weibull model was the highest. Conclusions Parametric models may provide complementary data for clinicians and researchers about how risks vary over time. The Weibull model seemed to show the best fit among the parametric models of the survival of hemodialysis patients.

Abstract
In the era of antiretroviral therapy, people living with HIV/AIDS live longer and are subject to co-morbidities that affect the general population, such as chronic kidney disease. An increasing number of people living with HIV/AIDS with end-stage renal disease are candidates for renal transplantation. Prior experience demonstrated that HIV-positive renal transplant recipients had acceptable survival but graft survival was decreased and rejection rates were increased, possibly due to suboptimal management of immunosuppressive medications in the face of drug interactions with antiretroviral therapy, particularly protease inhibitors and non-nucleoside reverse transcriptase inhibitors. Integrase strand transferase inhibitors are advantageous since they avoid drug-drug interactions with immunosuppressive drugs such as calcineurin inhibitors. We report clinical outcomes of 12 HIV-positive patients who underwent 13 kidney transplantations at our institution between 2000 and 2015. Cumulative survival was 75%, one-year and three-year survival were 100% and 63%. Integrase strand transferase inhibitor-based regimens were used in nine patients, of which eight survived. In patients on integrase strand transferase inhibitor, there was 100% graft survival and two had allograft rejection. In contrast, graft failure occurred in three patients on non-integrase strand transferase inhibitor-based regimens. Based on our study findings and on previously published data, we conclude that integrase strand transferase inhibitor-based therapy, preferably instituted prior to transplantation, is the preferred antiretroviral regimen in HIV-positive renal transplantation.

Abstract
Improved survival of human immunodeficiency virus (HIV) infected patients with chronic kidney disease following the introduction of antiretroviral therapy resulted in the need to revisit the topic of kidney transplantation in these patients. Large cohort studies have demonstrated favorable outcomes and proved that transplantation is a viable therapeutic option. However, HIV-infected recipients had higher rates of rejection. Immunosuppressive therapy did not negatively impact the course of HIV infection. Some of the immunosuppressive drugs used following transplantation exhibit antiretroviral effects. A close collaboration between infectious disease specialists and transplant professionals is mandatory in order to optimize transplantation outcomes in these patients. Transplantation from HIV+ donors to HIV+ recipients has been a subject of intense debate. The HIV Organ Policy Equity act provided a platform to research this area further and to develop guidelines. The first HIV+ to HIV+ kidney transplant in the United States and the first HIV+ to HIV+ liver transplant in the world were recently performed at the Johns Hopkins University Medical Center.

Abstract
INTRODUCTION With the introduction of combination antiretroviral therapy (cART), prognosis of human immunodeficiency virus (HIV) infection has been improved and kidney transplantation (KT) in HIV-positive patients became possible. METHODS We reviewed the demographic, clinical, laboratory, and therapeutic data of all the HIV-infected patients who underwent KT between 2009 (first KT in Portugal in a HIV-infected patient) and May 2014. Case accrual was through all Portuguese KT centers where a KT in an HIV-infected patient was performed. Patients were transplanted following the American and Spanish guideline recommendations that included maintenance on cART, undetectable plasma HIV RNA copies, and absolute CD4 counts of ≥ 200 cells/μL in the last 6 months. RESULTS Fourteen KT were performed on men and 3 on women. The mean age of patients at the time of transplantation was 49.9 ± 11.7 years. HIV status was known for 12 ± 5 years. Eight patients had AIDS in the past and all patients received grafts from deceased donors. Twelve patients (64.7%) underwent induction therapy with basiliximab and 2 patients experienced early graft loss. In 2 patients, humoral rejection was diagnosed and in 3 patients, cellular rejection. Two patients died and an additional patient had early graft loss. CONCLUSION KT is a possible, but challenging, renal replacement therapy in selected HIV-positive patients. Even in those with AIDS criteria in the past, when the disease is controlled, and after the reconstitution of the immune system with cART, KT can be performed. Nevertheless, the risk-benefit ratio for each patient needs to be taken in consideration.

Abstract
Patients on renal replacement therapy (RRT) infected with the human immunodeficiency virus (HIV) are a special group with growing interest. In order to study the epidemiological data of HIV+ patients on RRT in Spain, we collected individual information from 2004-2011 (period of use of highly active antiretroviral therapy [HAART] in the Autonomous Communities of Andalusia, Aragon, Asturias, Catalonia, Valencia, Castilla la Mancha, Castilla León, Galicia, Madrid, La Rioja and the Basque Country, comprising 85% of the Spanish population. A total of 271 incident and 209 prevalent patients were analysed. They were compared with the remaining patients on RRT during the same period. The annual incidence was 0.8 patients per one million inhabitants, with a significant increase during the follow-up period. The proportion of prevalent HIV+ patients was 5.1 per 1,000 patients on RRT (95% confidence interval [CI] 4.4-5.8. Although glomerular diseases constituted the majority of cases (42%), diabetic nephropathy was the cause in 14% of patients. The nation-wide totals for these percentages were 13 and 25%, respectively. Compared to the total of patients in treatment, the risk of death was significantly higher in the HIV+ group: hazard ratio (HR) adjusted for age, sex and diabetes was 2.26 (95% CI 1.74 - 2.91). Hepatitis C coinfection increased the risk of death in the HIV+ group (HR 1.77; 95% CI 1.10 - 2.85). The probability of kidney transplantation in HIV+ was only 17% after 7 years, comparing with total RTT patients (HR 0.15; 95% CI: 0.10-0.24). Despite the use of HAART, the incidence of HIV+ patients on dialysis has increased; their mortality still exceeds non-HIV patients, and they have a very low rate of transplantation. It is necessary to further our knowledge of this disease in order to improve results.

Abstract
HIV is a highly adaptive, rapidly evolving virus, which is associated with renal diseases including collapsing glomerulopathy-the classic histomorphological form of HIV-associated nephropathy. Other nephropathies related to viral factors include HIV-immune-complex kidney disease and thrombotic microangiopathy. The distribution of HIV-associated kidney diseases has changed over time and continues to vary across geographic regions worldwide. The reasons for this diversity are complex and include a critical role of APOL1 variants and possibly other genetic factors, disparities in access to effective antiviral therapies, and likely other factors that we do not yet fully understand. The mechanisms responsible for HIVAN, including HIV infection of podocytes and tubular epithelial cells, the molecules responsible for HIV entry, and diverse mechanisms of cell injury, have been the focus of much study. Although combined antiretroviral therapy is effective at preventing and reversing HIVAN, focal segmental glomerulosclerosis, arterionephrosclerosis and diabetic nephropathy are increasingly common in individuals who have received such therapy for many years. These diseases are associated with metabolic syndrome, obesity and premature ageing. Future directions for HIV-related kidney disease will involve regular screening for drug nephrotoxicity and incipient renal disease, as well as further research into the mechanisms by which chronic inflammation can lead to glomerular disease.

Abstract
BACKGROUND Human immunodeficiency virus (HIV)-infected adults, particularly those of black race, are at high-risk for end-stage renal disease (ESRD), but contributing factors are evolving. We hypothesized that improvements in HIV treatment have led to declines in risk of ESRD, particularly among HIV-infected blacks. METHODS Using data from the North American AIDS Cohort Collaboration for Research and Design from January 2000 to December 2009, we validated 286 incident ESRD cases using abstracted medical evidence of dialysis (lasting >6 months) or renal transplant. A total of 38 354 HIV-infected adults aged 18-80 years contributed 159 825 person-years (PYs). Age- and sex-standardized incidence ratios (SIRs) were estimated by race. Poisson regression was used to identify predictors of ESRD. RESULTS HIV-infected ESRD cases were more likely to be of black race, have diabetes mellitus or hypertension, inject drugs, and/or have a prior AIDS-defining illness. The overall SIR was 3.2 (95% confidence interval [CI], 2.8-3.6) but was significantly higher among black patients (4.5 [95% CI, 3.9-5.2]). ESRD incidence declined from 532 to 303 per 100 000 PYs and 138 to 34 per 100 000 PYs over the time period for blacks and nonblacks, respectively, coincident with notable increases in both the prevalence of viral suppression and the prevalence of ESRD risk factors including diabetes mellitus, hypertension, and hepatitis C virus coinfection. CONCLUSIONS The risk of ESRD remains high among HIV-infected individuals in care but is declining with improvements in virologic suppression. HIV-infected black persons continue to comprise the majority of cases, as a result of higher viral loads, comorbidities, and genetic susceptibility.

Abstract
BACKGROUND The use of highly active antiretroviral therapy (HAART) has decreased the morbidity and mortality in HIV-infected patients. The kidney transplantation (KT) survival rate is similar to that of HIV-negative transplant recipients. The consensus criteria for the selection of HIV patients for transplantation include: no opportunistic infections, CD4 lymphocyte count greater than 200 cells/μL, and an undetectable viral load. In Spain, HIV-infected patients present with different characteristics compared to American recipients; this could influence posttransplantation outcomes. OBJECTIVE This study analyzed the outcome and the clinical characteristics of HIV-infected patients who received KT in Spain in the HAART era. METHODS We retrospectively reviewed the clinical charts of seven adult HIV-infected recipients of primary renal allografts between January 2001 and June 2012. Patient inclusion criteria met the American and Spanish guidelines. The immunosuppressive protocol consisted of tacrolimus, mycophenolate mofetil, and steroids. RESULTS The median age was 44.8 years (interquartile amplitude = 9.4). The predominant mode of transmission was intravenous drug use (71.4%) and hepatitis C virus coinfection (71.4%). The most frequent cause of end-stage renal disease was glomerulonephritis (57.1%). Six patients (85.7%) were on HAART. All patients had controlled HIV infections with undetectable viral load and a median CD4 lymphocyte count of 504 cells/μL (IQA 599). Patients were followed for a median of 16.0 months (range, 3.0 to 96.6 months). Delayed graft function and acute rejection rates were 60% and 40%, respectively. The median creatinine level at the last follow-up was 1.58 mg/dL (IQA 1.15). In one case, a high-grade Epstein-Barr virus-related B cell lymphoma was diagnosed at 83 months after renal transplantation. CONCLUSIONS Kidney transplantation in HIV-infected patients is a safe, effective treatment for selected patients. Midterm graft survival was comparable to that of HIV-negative patients.

Abstract
Antiretroviral therapy has been immensely successful in reducing the incidence of opportunistic infections and death after HIV infection. This has resulted in heightened interest in noninfectious comorbidities including kidney disease. Although HIV-associated nephropathy, the most ominous kidney disease related to the direct effects of HIV, may be prevented and treated with antiretrovirals, kidney disease remains an important issue in this population. In addition to the common risk factors for kidney disease of diabetes mellitus and hypertension, HIV-infected individuals have a high prevalence of other risk factors, including hepatitis C and exposure to antiretrovirals and other medications. Therefore, the differential diagnosis is vast. Early identification (through efficient screening) and prompt treatment of kidney disease in HIV-infected individuals are critical to lead to better outcomes. This review focuses on clinical and epidemiological issues, treatment strategies (including dialysis and kidney transplantation), and recent advances among kidney disease in the HIV population.

Abstract
HIV-associated nephropathy (HIVAN) is the manifestation of HIV gene expression by kidney cells in the presence of specific host factors. Recently, rapamycin (sirolimus) has been demonstrated to modulate the progression of HIVAN. We hypothesized that rapamycin would modulate the progression of HIVAN by attenuating HIV gene expression. To test our hypothesis, three weeks old Tg26 mice (n=6) were administered either vehicle or rapamycin (5 mg/kg, every other day, intraperitoneal) for eight weeks. At the end of the experimental period, the kidneys were harvested. In in vitro studies, human podocytes were transduced with either HIV-1 (NL4-3) or empty vector (EV), followed by treatment with either vehicle or rapamycin. Total RNA and proteins were extracted from renal tissues/cellular lysates and HIV gene transcription/translation was measured by real time PCR and Western blotting studies. Renal histological slides were graded for glomerular sclerosis and tubular dilatation with microcyst formation. Rapamycin attenuated both glomerular and tubular lesions in Tg26 mice. Rapamycin decreased transcription of HIV genes both in renal tissues as well as in HIV-1 transduced podocytes. Our data strongly indicate that HIV-1 long terminal repeat-mediated transcriptional activity was targeted by rapamycin. Rapamycin enhanced podocyte NF-κB and CREB activities but then it decreased AP-1 binding activity. Since expression of HIV genes by kidney cells has been demonstrated to be the key factor in the development HIVAN, it appears that rapamycin-induced altered transcription of HIV genes might have partly contributed to its disease modulating effects.

Abstract
OBJECTIVES Renal disease is a common and serious complication in HIV-infected patients. METHODS A retrospective cohort analysis for the period 1989-2010 was carried out to determine the prevalence, incidence and risk factors for end-stage renal disease (ESRD). ESRD was defined as initiation of renal replacement therapy. Three time periods were defined: 1989-1996 [pre-highly active antiretroviral therapy (HAART)], 1997-2003 (early HAART) and 2004-2010 (late HAART). RESULTS Data for 9198 patients [78.2% male; 88.9% Caucasian; cumulative observation time 68 084 patient-years (PY)] were analysed. ESRD was newly diagnosed in 35 patients (0.38%). Risk factors for ESRD were Black ethnicity [relative risk (RR) 5.1; 95% confidence interval (CI) 2.3-10.3; P < 0.0001], injecting drug use (IDU) (RR 2.3; 95% CI 1.1-4.6; P = 0.02) and hepatitis C virus (HCV) coinfection (RR 2.2; 95% CI 1.1-4.2; P = 0.03). The incidence of ESRD decreased in Black patients over the three time periods [from 788.8 to 130.5 and 164.1 per 100 000 PY of follow-up (PYFU), respectively], but increased in Caucasian patients (from 29.9 to 41.0 and 43.4 per 100 000 PYFU, respectively). The prevalence of ESRD increased over time and reached 1.9 per 1000 patients in 2010. Mortality for patients with ESRD decreased nonsignificantly from period 1 to 2 (RR 0.72; P = 0.52), but significantly from period 1 to 3 (RR 0.24; P = 0.006), whereas for patients without ESRD mortality decreased significantly for all comparisons. ESRD was associated with a high overall mortality (RR 9.9; 95% CI 6.3-14.5; P < 0.0001). CONCLUSION As a result of longer survival, the prevalence of ESRD is increasing but remains associated with a high mortality. The incidence of ESRD declined in Black but not in Caucasian patients. IDU and HCV were identified as additional risk factors for the development of ESRD.

Abstract
Purpose There is a limited source of information about vascular access outcomes in HIV-positive patients in the literature. Previous studies have shown autogenous arteriovenous fistulae (AVF) to have similar cumulative survival rates in HIV-positive and negative patients but functional patency has not been assessed. The primary aim of this study was to investigate functional patency of AVFs in HIV-positive patients. Methods A retrospective case-control study identifying 17 HIV-positive patients with AVFs under the care of renal services at Kings College Hospital, London was undertaken. Seventeen HIV-negative controls were matched for age, sex, ethnicity, and co-morbidities. Comparisons were made for pre-operative vein diameter, primary and functional patencies, and postoperative complications. Results No statistically significant difference was seen for functional patency between AVFs in the HIV-positive and control groups (P=.078). Complications were experienced by five HIV-positive patients (29.4%) and nine of the control group (52.9%). These included aneurysms and pseudoaneurysms for both groups. The difference in pre-operative vein diameter was not significant (P=.102), although only five of the HIV-positive patients had pre-operative vein diameters >=2.5 mm (45.5%) compared to twelve of the controls (75%). Conclusions This study reveals that there is no statistically significant difference between the functional patency of autogenous AVFs in HIV-positive patients compared to HIV-negative controls. With less than half of the HIV-positive patients having pre-operative vein diameters >=2.5 mm, this suggests that it is still worth creating AVFs in patients with sub-optimal veins considering the known poorer patency with non-autogenous fistulae.

Abstract
BACKGROUND/AIMS Although HIV-infected persons are at higher risk for acute kidney injury (AKI) during hospitalization compared with their uninfected counterparts, risk factors for AKI are not well-defined. We aimed to describe the evolving incidence of AKI among HIV-infected individuals and to identify important AKI risk factors. METHODS We conducted a prospective cohort study of 56,823 HIV-infected persons in the Department of Veterans Affairs Clinical Case Registry. Outcomes were: AKI (acute in-hospital serum creatinine increase of ≥0.3 mg/dl, or a relative increase by 50% or greater), and dialysis-requiring AKI. We used proportional hazards regressions to identify risk factors. RESULTS From its peak in 1995 at 62 per 1,000 person-years, the incidence of AKI declined after the introduction of highly active antiretroviral therapy (HAART) in 1996 to a low point of 25 per 1,000 person-years in 2006. Incidence of dialysis-requiring AKI declined in the early 1990s, but doubled between 2000 and 2006. Using multivariate proportional hazard regression, we identified the following strong risk factors for AKI: chronic kidney disease (eGFR <60 ml/min/1.73 m(2)) (5.38, 95% CI: 5.11-5.67), proteinuria (1.78, 1.70-1.87), low serum albumin (<3.7 mg/dl) (5.24, 4.82-5.71), low body mass index (<18.5 kg/m(2)) (1.69, 1.54-1.86), cardiovascular disease (1.77, 1.66-1.89), low CD4 count (<200 cells/mm(3)) (2.54, 2.33-2.77), and high viral load (≥100,000 copies/ml) (2.51, 2.28-2.75). In addition, there was substantial heterogeneity in the strengths of risk factors for dialysis-requiring AKI before and after the introduction of HAART. CONCLUSIONS Although AKI incidence has decreased during the HAART era, it remains common in HIV-infected persons and appears attributable to both kidney- and HIV-related factors.

Abstract
Patients' deaths due to the organ donor shortage make it imperative that every suitable organ be transplanted. False-positive results of tests for infection with the human immunodeficiency virus (HIV) result in lost organs. A survey of US organ procurement organizations collected the numbers of donors and ruled-out potential donors who had a positive result on an HIV test from January 1,2006, to October 31, 2008. Sixty-two percent of US organ procurement organizations participated. Of the 12397 donor/nondonor cases, 56 (0.45%) had an initial positive result on an HIV antibody or HIV nucleic acid test, and only 8 (14.3%) of those were confirmed positive. Of the false-positive results, 50% were from HIV antibody tests and 50% were from HIV nucleic acid tests. Organs are a scarce, finite, and perishable resource. Use of HIV antibody testing has produced a remarkably safe track record of avoiding HIV transmission, with 22 years of nonoccurrence between transmissions. Because false positives occur with any test, including the HIV Ab test, adding nucleic acid testing to the standard donor testing panel doubles the number of false-positive HIV test results and thus the number of medically suitable donors lost. The required HIV antibody test is 99.99% effective in preventing transmission of the HIV virus. Adding the HIV nucleic acid test to routine organ donor screening could result in as many as 761 to 1551 unnecessary deaths of patients between HIV transmission events because medically suitable organs are wasted.

Abstract
The prognosis of human immunodeficiency virus (HIV) infection has improved in recent years with the introduction of antiretroviral treatment. While the frequency of AIDS-defining events has decreased as a cause of death, mortality from non-AIDS-related events including end-stage renal diseases has increased. The etiology of chronic kidney disease is multifactorial: immune-mediated glomerulonephritis, HIV-associated nephropathy, thrombotic microangiopathies, and so on. HIV infection is no longer a contraindication to transplantation and is becoming standard therapy in most developed countries. The HIV criteria used to select patients for renal transplantation are similar in Europe and North America. Current criteria state that prior opportunistic infections are not a strict exclusion criterion, but patients must have a CD4+ count above 200 cells/mm(3) and a HIV-1 RNA viral load suppressible with treatment. In recent years, more than 200 renal transplants have been performed in HIV-infected patients worldwide, and mid-term patient and graft survival rates have been similar to that of HIV-negative patients. The main issues in post-transplant period are pharmacokinetic interactions between antiretrovirals and immunosuppressants, a high rate of acute rejection, the management of hepatitis C virus coinfection, and the high cardiovascular risk after transplantation. More studies are needed to determine the most appropriate antiretroviral and immunosuppressive regimens and the long-term outcome of HIV infection and kidney graft.

Abstract
Kidney transplantation is now considered as a reasonable option for HIV-infected patients with end-stage renal disease. We describe here a retrospective study conducted in five transplantation centers in Paris. Twenty-seven patients were included. Immunosuppressive protocol associated an induction therapy and a long-term treatment combining mycophenolate mofetil, steroids and either tacrolimus or cyclosporine. All the patients had protocol biopsies at 3 months and 1 year. Patient's survival was 100% at 1 year and 98% at 2 years. Graft survival at 1 and 2 years is 98% and 96% at 1 and 2 years, respectively. The mean glomerular filteration rate values at 12 and 24 months were 60.6 mL/min/1.73 m² (range 23-98) and 65.4 mL/min/1.73 m² (range 24-110), respectively. Acute cellular rejection was diagnosed in four cases (15%). Because of high trough levels of calcineurin inhibitor, protease-inhibitor therapies were withdrawn in 11 cases. HIV disease progression was not observed. One patient developed B-cell lymphoma. In conclusion, our study confirms the safety of renal transplantation in HIV-infected patients with few adverse events and a low incidence of acute rejection.

Abstract
Antiretroviral therapy has revolutionized the care of individuals infected with the human immunodeficiency virus (HIV) and has fundamentally altered the scope of the disease. Acute renal failure and chronic kidney disease from medication toxicity and comorbid noninfectious illnesses are just as likely today as end-organ injury from the virus itself. Chronic immunosuppression renders HIV-infected patients vulnerable to any of several unique urological infections not frequently seen in immunocompetent patients. A deeper understanding of renal and urological emergencies in the context of the HIV-infected patient will better prepare the emergency physician to render optimal care to this rapidly expanding and aging patient population.
