Abstract
Advances in antiretroviral and immunosuppressive regimens have improved outcomes following solid organ transplantation in people living with HIV (PLWH). The HIV Organ Policy and Equity Act was conceived to reduce the discard of HIV-positive organs and improve access to transplant for PLWH. Nevertheless, PLWH continue to experience disproportionately low rates of transplant. This overview examines the hurdles to transplantation in PLWH with end-organ disease, the potential and realized impact of the HIV Organ Policy and Equity Act, and changes that could permit expanded access to organ transplant in this population.

Abstract
The epidemiology of human immunodeficiency virus (HIV) has shifted such that Black individuals disproportionately represent incident HIV diagnoses. While risk of end-stage kidney disease (ESKD) among people with HIV (PWH) has declined with effective antiretroviral therapies, a substantial racial disparity in ESKD burden exists with the greatest prevalence among Black PWH. Disparities in waitlisting for kidney transplantation, the optimal treatment for ESKD, exist for both PWH and Black individuals without HIV, but it is unknown whether these characteristics together exacerbate such disparities. Six hundred two thousand six ESKD patients were identified from the United States Renal Data System (January 1, 2007 to December 31, 2017), and HIV-status was determined through Medicare claims. Cox proportional hazards regression was used to determine waitlisting rates. Multiplicative interaction terms between HIV-status and race were examined. The 6250 PWH were significantly younger, more commonly Black, and less commonly female than those without HIV. HIV-status and race were independently associated with 50% and 12% lower likelihood of waitlisting, respectively [adjusted hazard ratio (aHR): 0.50, 95% confidence interval (CI): 0.36-0.69, p < 0.001; aHR: 0.88, 95% CI: 0.87-0.90, p < 0.001]. There was also a significant interaction present between HIV-status and Black race (aHR: 0.80, 95% CI: 0.66-0.98, p < 0.001) such that, while HIV-status and Black race were independently associated with decreased waitlisting, the interaction of Black race and HIV-status exacerbated those disparities. While limited by lack of HIV-specific data that may impact inferences with respect to race, additional studies are urgently needed to understand the interplay between HIV risk factors, HIV-stigma, and racism, and how intersectionality may exacerbate disparities in transplantation among PWH.

Pharmacotherapeutic Interventions in People Living With HIV Undergoing Solid Organ Transplantation: A Scoping Review. Transplant Direct 2023; 9:e1441. [PMID: 36733439 PMCID: PMC9886517 DOI: 10.1097/txd.0000000000001441] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 12/01/2022] [Accepted: 12/03/2022] [Indexed: 01/28/2023] Open
Abstract
The pharmacotherapeutic management of people living with HIV (PLWHIV) undergoing solid organ transplantation (SOT) is clinically challenging, mainly due to the frequent occurrence of complex drug-drug interactions. Although various strategies have been proposed to improve treatment outcomes in these patients, several uncertainties remain, and consensus practice guidelines are just beginning to emerge. The main objective of this scoping review was to map the extent of the literature on the pharmacotherapeutic interventions performed by healthcare professionals for PLWHIV undergoing SOT. Methods We searched Medline, Embase, and the Cochrane databases as well as gray literature for articles published between January 2010 and February 2020. Study selection was performed by at least 2 independent reviewers. Articles describing pharmacotherapeutic interventions in PLWHIV considered for or undergoing SOT were included in the study. Results Of the 12 599 references identified through our search strategy, 209 articles met the inclusion criteria. Results showed that the vast majority of reported pharmacotherapeutic interventions concerned the management of immunosuppressive and antimicrobial therapy, including antiretrovirals. Analysis of the data demonstrated that for several aspects of the pharmacotherapeutic management of PLWHIV undergoing SOT, there were differing practices, such as the choice of immunosuppressive induction and maintenance therapy. Other important aspects of patient management, such as patient counseling, were rarely reported. Conclusions Our results constitute an extensive overview of current practices in the pharmacotherapeutic management of SOT in PLWHIV and identify knowledge gaps that should be addressed to help improve patient care in this specific population.

Abstract
The HIV latent viral reservoir (LVR) remains a major challenge in the effort to find a cure for HIV. There is interest in lymphocyte-depleting agents, used in solid organ and bone marrow transplantation to reduce the LVR. This study evaluated the LVR and T cell receptor repertoire in HIV-infected kidney transplant recipients using intact proviral DNA assay and T cell receptor sequencing in patients receiving lymphocyte-depleting or lymphocyte-nondepleting immunosuppression induction therapy. CD4+ T cells and intact and defective provirus frequencies decreased following lymphocyte-depleting induction therapy but rebounded to near baseline levels within 1 year after induction. In contrast, these biomarkers were relatively stable over time in the lymphocyte-nondepleting group. The lymphocyte-depleting group had early TCRβ repertoire turnover and newly detected and expanded clones compared with the lymphocyte-nondepleting group. No differences were observed in TCRβ clonality and repertoire richness between groups. These findings suggest that, even with significant decreases in the overall size of the circulating LVR, the reservoir can be reconstituted in a relatively short period of time. These results, while from a relatively unique population, suggest that curative strategies aimed at depleting the HIV LVR will need to achieve specific and durable levels of HIV-infected T cell depletion.

Abstract
BACKGROUND The emergence of potent combined highly active antiretroviral therapy (ART) in 1996 changed the natural history of HIV infection, with a significant reduction in mortality due to opportunistic infections but increased morbidity due to chronic cardiovascular, hepatic, and renal diseases. In May 2016, a reference center for liver transplantation in the Northeast of Brazil performed the first liver transplantations (LT) in HIV patients, with five others until 2021. METHODS The criteria for selection of LT were good adherence and absence of resistance to ART, HIV viral load maximum suppression, T-CD4+ lymphocyte count of more than 100 cells/mm3, and absence of opportunistic infections in the last 6 months. RESULTS Six liver transplants were performed between May 2016 and May 2021, five men, with a mean age of 53.2 years, and one was a diabetic patient. All patients had access to grafts with short cold ischemia with a mean time of 5 hours and 39 minutes. The 4-month survival rate was 100%, with a range time of follow-up of 4-63 months (mean time of 31 months). The mean pre-transplant T-CD4+ lymphocyte count was 436 cells/mm3. The mean length of hospital stay after transplantation was 16.8 days. One patient presented precocious vena cava thrombosis; another had stenosis of cavocaval anastomosis leading to refractory ascites, renal failure and post-transplant graft dysfunction, and another presented stenosis of choledochal anastomosis. Immunosuppression and prophylaxis were used according to standard protocols, and there were no differences in the profile of infections or rejection after liver transplantation. CONCLUSION This case series documents good survival and usual transplant procedures for confirmed HIV cases.

Abstract
PURPOSE OF REVIEW The HIV Organ Policy Equity (HOPE) Act permits transplantation from donors-with-HIV to recipients-with-HIV (HIV D + /R +). We assess HOPE implementation, summarizing progress and challenges at clinical, legislative, and community levels. RECENT FINDINGS As of July 2021, there have been 300 kidney and 87 liver transplants within HOPE research studies in the USA. Early HIV D + /R + kidney transplant outcomes show excellent patient survival (100%) and graft survival (92%). The number of HOPE donors continues to grow annually but remains lower than projections. State-level policy restrictions are identified in 34 states; however, these do not seem to have impacted practice; 16 states have passed new legislation to facilitate HIV D + /R + transplantation. Stigma related to HIV and low donor registration rates pose additional barriers. SUMMARY Early outcomes of HOPE Act transplants are encouraging. Progress to reach full implementation and realize the full benefit of this innovation is ongoing.

Abstract
PURPOSE OF REVIEW Advances in antiretroviral therapy (ART) have transformed HIV infection into a chronic and manageable condition. The introduction of potent and more tolerable antiretrovirals (ARVs) with favorable pharmacokinetic profiles has changed the prevalence and nature of drug-drug interactions (DDIs). Here, we review the relevance of DDIs in the era of contemporary ART. RECENT FINDINGS Management of DDIs remains an important challenge with modern ART, primarily due to increased polypharmacy in older persons living with HIV. Significant DDIs exist between boosted ARVs or older nonnucleoside reverse transcriptase inhibitors and comedications for chronic comorbidities (e.g., anticoagulants, antiplatelets, statins) or complex conditions (e.g., anticancer agents, immunosuppressants). Newer ARVs such as unboosted integrase inhibitors, doravirine, and fostemsavir have reduced DDI potential, but there are clinically relevant DDIs that warrant consideration. Potential consequences of DDIs include increased toxicity and/or reduced efficacy of ARVs and/or comedications. Management approaches include switching to an ARV with less DDI potential, changing comedications, or altering medication dosage or dosing frequency. Deprescribing strategies can reduce DDIs and polypharmacy, improve adherence, minimize unnecessary adverse effects, and prevent medication-related errors. SUMMARY Management of DDIs requires close interdisciplinary collaboration from multiple healthcare disciplines (medicine, nursing, pharmacy) across a spectrum of care (community, outpatient, inpatient).

Abstract
HIV-positive donor to HIV-positive recipient (HIV D+/R+) transplantation is permitted in the United States under the HIV Organ Policy Equity Act. To explore safety and the risk attributable to an HIV+ donor, we performed a prospective multicenter pilot study comparing HIV D+/R+ vs HIV-negative donor to HIV+ recipient (HIV D-/R+) kidney transplantation (KT). From 3/2016 to 7/2019 at 14 centers, there were 75 HIV+ KTs: 25 D+ and 50 D- (22 recipients from D- with false positive HIV tests). Median follow-up was 1.7 years. There were no deaths nor differences in 1-year graft survival (91% D+ vs 92% D-, P = .9), 1-year mean estimated glomerular filtration rate (63 mL/min D+ vs 57 mL/min D-, P = .31), HIV breakthrough (4% D+ vs 6% D-, P > .99), infectious hospitalizations (28% vs 26%, P = .85), or opportunistic infections (16% vs 12%, P = .72). One-year rejection was higher for D+ recipients (50% vs 29%, HR: 1.83, 95% CI 0.84-3.95, P = .13) but did not reach statistical significance; rejection was lower with lymphocyte-depleting induction (21% vs 44%, HR: 0.33, 95% CI 0.21-0.87, P = .03). In this multicenter pilot study directly comparing HIV D+/R+ with HIV D-/R+ KT, overall transplant and HIV outcomes were excellent; a trend toward higher rejection with D+ raises concerns that merit further investigation.

Improved ability to achieve target trough levels with liquid versus capsule tacrolimus in kidney transplant patients with HIV on protease inhibitor- or cobicistat-based regimens. Transpl Infect Dis 2020; 23:e13517. [PMID: 33217091 DOI: 10.1111/tid.13517] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2019] [Revised: 09/19/2020] [Accepted: 10/25/2020] [Indexed: 11/30/2022]
Abstract
HIV + patients are commonly accepted for kidney transplantation. However, patients on protease inhibitor (PI)- or cobicistat (cobi)-based regimens have trouble achieving optimal tacrolimus (Tac) levels. Our study compared the ability to achieve target levels using liquid versus immediate-release capsule Tac in kidney transplant patients with HIV on PI- or cobi-based regimens. The study included four kidney transplant patients who were converted to liquid Tac due to inability to achieve acceptable drug levels on the capsule formulation. Tac trough levels were analyzed retrospectively to compare target levels before and after conversion. The individual patient time in the therapeutic range (TTR) was calculated using Rosendaal's linear interpolation method, and the difference between before and after conversion TTR was determined. In combined data, 44.63% of all Tac trough levels were within the target range after conversion to liquid Tac compared to 22.07% prior to conversion (P < .001). Furthermore, 3.31% and 7.44% of Tac trough levels were lower than 3 ng/mL or higher than 12 ng/mL, respectively, after conversion compared to 11.72% (P = .0564) and 24.14% (P < .0001) prior to conversion. The overall mean TTR was 45.1% after conversion to liquid Tac compared to 16.2% prior to conversion (P = .097). Finally, the coefficient of variation for Tac trough levels was 42.6 after conversion compared to 56.4 prior to conversion. A significantly improved ability to achieve target trough Tac levels was achieved with liquid Tac extemporaneous versus capsule formulation in kidney transplant patients with HIV taking a PI- or cobi-based regimen.

Outcomes of donor-derived superinfection screening in HIV-positive to HIV-positive kidney and liver transplantation: a multicentre, prospective, observational study. Lancet HIV 2020; 7:e611-e619. [PMID: 32730756 PMCID: PMC8073978 DOI: 10.1016/s2352-3018(20)30200-9] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Revised: 04/23/2020] [Accepted: 05/04/2020] [Indexed: 01/23/2023]
Abstract
BACKGROUND One of the primary risks of HIV-positive to HIV-positive organ transplantation is loss of virological control because of donor-derived HIV superinfection, which occurs when an HIV-positive individual becomes infected with a new distinct HIV strain. In this study, as part of the larger HIV Organ Policy Equity pilot study, HIV-positive to HIV-positive kidney and liver transplant recipients in the USA were examined for evidence of sustained donor-derived HIV superinfection. METHODS In this multicentre, prospective, observational study, HIV-positive to HIV-positive kidney and liver transplant recipients were followed in three hospitals in the USA. Candidates with well controlled HIV infection on ART, no active opportunistic infections, and minimum CD4 T-cell counts (>100 cells per μL for liver and >200 cells per μL for kidney per federal guidelines) were eligible to receive a kidney or liver from deceased HIV-positive donors without active infections or neoplasm. Peripheral blood mononuclear cells were collected from donor-recipient pairs at the time of transplantation, and from recipients at several timepoints up to 3 years after transplantation. Donor samples were assessed for HIV RNA viral load, CD4 cell count, and antiretroviral drug-resistant mutations. Donor and recipient HIV proviral DNA, and viral RNA from the viraemic timepoint were sequenced using a site-directed next-generation sequencing assay for the reverse transcriptase and gp41 genes. Neighbour-joining phylogenetic trees and direct sequence comparison were used to detect the presence of HIV superinfection. This study is registered with ClinicalTrials.gov, NCT02602262. FINDINGS 14 HIV-positive to HIV-positive kidney and eight liver transplant recipients were followed from March, 2016, to July, 2019. 17 recipients had adequate viral sequences allowing for HIV superinfection assessment. Eight donors were suppressed (viral load <400 copies per mL), and none had multiclass drug-resistant mutations detected. None of the recipients examined had evidence of HIV superinfection. One recipient had a viraemic episode (viral load of 2 080 000 copies per mL) 3 years after transplantation as a result of non-adherence to ART. Only recipient viral sequences were detected during the viraemic episode, suggesting that the donor virus, if present, was not reactivated despite temporary withdrawal of ART. INTERPRETATION These findings suggest that loss of HIV suppression due to donor-derived HIV superinfection might not be a significant clinical concern in carefully monitored ART suppressed HIV-positive organ recipients.

Comparative analysis of outcomes after liver resection and liver transplantation for early stages hepatocellular carcinoma in HIV-infected patients. An intention-to-treat analysis. HPB (Oxford) 2020; 22:900-910. [PMID: 31734238 DOI: 10.1016/j.hpb.2019.10.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2019] [Revised: 09/15/2019] [Accepted: 10/01/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND To address the results of resection for hepatocellular carcinoma (HCC) in human immunodeficiency virus (HIV)-carriers, and to compare them against survival after liver transplantation (LT). METHODS All patients with HIV and HCC listed for LT (candidates = LTc+) or resection (LR+) between 2000 and 2017 in our centre were analysed and compared for overall survival (OS) and disease-free survival (DFS). RESULTS The LTc + group (n = 43) presented with higher MELD scores and more advanced portal hypertension and HCC stages than LR + group (n = 15). One-, 3- and 5-year intention-to-treat survival rates were: 81%, 60% and 44%, versus 86%, 58% and 58% in the LTc+ and LR + groups, respectively (p = 0.746). Eleven LTc + patients dropped out. After LT, OS was 81%, 68% and 59% (no difference with LR + group; p = 0.844). There tended to be better DFS after LT, reaching 78%, 68% and 56% versus 53%, 33% and 33% in the LR + group (p = 0.062). CONCLUSION This was the largest series of resections for HCC in HIV + patients and the first intention-to-treat analysis. Although LT and resection do not always concern the same population, they enable equivalent survival. At the price of higher recurrence rate, resection could be integrated in the global armoury of liver surgeons.

Abstract
PURPOSE OF REVIEW We report the current state of HIV+ to HIV+ kidney transplantation in the United States and remaining challenges in implementing this practice nationally. RECENT FINDINGS The HIV Organ Policy Equity (HOPE) Act, which was the first step in unlocking the potential of HIV+ organ donors, mandates clinical research on HIV+ to HIV+ transplantation. As of March 2019, there have been 57 HOPE donors, including both true and false positive HOPE donors resulting in more than 120 transplants. SUMMARY The HOPE Act, signed in 2013, reversed the federal ban on the transplantation of organs from HIV+ donors into HIV+ recipients. Ongoing national studies are exploring the safety, feasibility, and efficacy of both kidney and liver transplantation in this population. If successfully and fully implemented, HIV+ to HIV+ transplantation could attenuate the organ shortage for everyone waiting, resulting in a far-reaching public health impact.

Abstract
: The field of HIV treatment and prevention has evolved rapidly over the past four decades. New therapies that are more potent and streamlined have transformed HIV into a chronic disease, while the use of such preventive strategies as preexposure prophylaxis and postexposure prophylaxis provide effective options for reducing the risk of HIV infection. These medical breakthroughs have enabled more people living with HIV (PLWH) to reach older adulthood. But they also mean that nurses are seeing more PLWH who have developed long-term complications of living with HIV or of exposure to antiretroviral therapy, as well as concurrent chronic conditions associated with advanced age. Nurses play a critical role in caring for PLWH and those at risk for HIV infection. This article discusses HIV epidemiology, describes the current state of HIV treatment and prevention, and highlights common comorbidities often seen in PLWH who are over age 50.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) infection affects nearly 38 million people worldwide. Patients living with HIV (PLHIV) on modern highly active antiretroviral therapy face significant morbidity and mortality related to the progression of chronic diseases, which lead to an increase in the burden of end-stage organ disease and organ failure. PLHIV present a two fold increased risk of heart failure as compared with the general population, with a prevalence of clinical heart failure of 6.5 %. Orthotopic heart transplantation (OHT) is rarely performed in HIV-positive patients despite the fact that HIV-associated cardiomyopathy is a major long-term complication of HIV infection. MATERIAL AND METHODS We present a case of PLHIV presenting with decompensated heart failure, requiring initial therapy with left ventricular assist device, followed by heart transplantation, accompanied by an update on current concepts, and experience in the field. DISCUSSION AND CONCLUSION HIV-associated cardiomyopathy is a major long-term complication of HIV infection. LVAD support or OHT should also be encouraged among HIV-positive patients as current data indicates that AHFT is safe in carefully selected HIV-positive patients and outcomes are similar to those of HIV-negative patients.

Abstract
PURPOSE OF REVIEW HIV-infected (HIV+) and hepatitis C virus-infected (HCV+) individuals with end-stage renal disease (ESRD) have decreased access to kidney transplantation. With new opportunities provided by the HIV Organ Policy Equity (HOPE) Act and direct-acting antivirals (DAAs) for HCV, we explore the potential risks and benefits of living donor kidney transplantation from HIV+ or HCV+ donors, from the perspective of both donor health and recipient outcomes. RECENT FINDINGS The HOPE Act permits organ donation from both deceased and living HIV+ persons to HIV+ recipients; however, there is only clinical experience with HIV+ deceased donors to date. Empirical evidence demonstrates a low but acceptable risk of ESRD in potential HIV+ living donors without comorbidities who have well-controlled infection in the absence of donation. With the availability of potent DAAs for eradication of HCV infection, growing evidence shows good outcomes with HCV seropositive and/or viremic deceased kidney donors, providing rationale to consider HCV+ living donors. SUMMARY HIV+ and HCV+ living donor kidney transplantation may improve access to transplant for vulnerable ESRD populations. Careful evaluation and monitoring are warranted to mitigate potential risks to donors and recipients.

Abstract
BACKGROUND Scarce data are available about immune cell frequencies in HIV-positive recipients of liver transplant. Alterations in immune subsets can lead to persistent immune activation and disease progression or reduced HIV-specific responses. In liver transplantation, impaired immune tolerance can lead to organ rejection. METHODS HIV-positive subjects with undetectable HIVRNA and CD4 > 100/mm3 were included. Control groups were non-transplanted HIV-positive patients with similar immunovirological parameters and healthy subjects. B cells (memory, transitional, and mature subsets), T cells (effector TH1, nonclassic TH1, TH17, TH1/17; T regulatory naïve and effector subsets and CD8+ T regulatory cells), and NK cells (CD56dim and CD56bright subsets) were analyzed by flow cytometry. RESULTS A total of 56 patients, including 14 HIV-positive transplant recipients (HIV-LT), 14 HIV-positive controls, and 28 healthy controls were included. Median age of HIV-LT patients was 54.9 years with median time from transplant of 7.6 years. Eleven (79%) were HIV/HCV coinfected. Compared to nontransplanted patients, HIV-LT displayed significantly increased frequency of T CD8+ cells, lower percentage of T CD4+ cell, and lower number of nonclassic TH1, TH1/17 cells and naïve T CD4+ regulatory cells (Tregs). Healthy controls showed increased numbers of B cell subsets and decreased percentage of T effector subpopulations compared to HIV-LT. Compared to HIV-positive patients, healthy controls had higher B cells, NK cells, CD4+ T cells, naïve CD4+ Tregs but lower CD8+ T cells, effector Tregs, CD8+ Tregs, and all T effector cell subsets. CONCLUSIONS Immune cell subpopulations potentially associated with HIV progression and organ rejection were detected in HIV-positive transplant recipients. We confirmed altered frequencies of B, T, and NK cell populations in HIV-positive liver transplant recipients compared to healthy controls. The imbalance among immune cell subsets deserves further studies to identify markers of transplant outcome and potential therapeutic targets.

Abstract
These updated guidelines from the Infectious Diseases Community of Practice of the American Society of Transplantation provide an update on potential drug-drug interactions between anti-infectives and immunosuppressants, which are most notable with calcineurin and mTOR inhibitors. Drug-drug interactions may occur through pharmacokinetic mechanisms leading to altered drug concentrations of either the anti-infective or immunosuppressive drug, or by pharmacodynamic interactions increasing or decreasing the efficacy or toxicity of the medications. Many of the significant pharmacokinetic interactions occur through inhibition or induction of the cytochrome 3A4 system by anti-infective agents leading to increased or decreased immunosuppressive agent levels, respectively. The membrane transporter P-glycoprotein is also often involved in drug interactions. Since the last iteration of these guidelines, multiple new hepatitis C virus direct-acting antivirals have become available for use in SOT recipients. Of these agents, some are substrates of cytochrome and drug transporter systems, while others inhibit these systems and may affect immunosuppressive agents. Due to the high risk for drug-drug interactions in the solid organ transplant population, practitioners must be aware of potential interactions and be vigilant in monitoring and adjusting drug dosing when appropriate.
