Organ transplantation in Africa: Confronting socioeconomic, cultural, and infrastructural hurdles

BACKGROUND

Organ transplantation is a critical procedure offering life-saving treatment for patients with end-stage organ failure. In Africa, however, the accessibility and development of organ transplantation are severely hampered by numerous barriers. Socioeconomic disparities, inadequate healthcare infrastructure, legal and ethical gaps, cultural resistance, and the dual burden of infectious and non-communicable diseases are among the significant challenges faced. This review aims to comprehensively explore these barriers and propose actionable strategies to address them.

METHOD

A narrative review was conducted by searching electronic databases, including PubMed, Google Scholar, Scopus, and JSTOR. The review prioritized studies addressing the challenges of organ transplantation in Africa, focusing on socioeconomic factors, healthcare infrastructure, cultural beliefs, legal frameworks, and the impact of infectious and non-communicable diseases. Studies offering solutions tailored to the African context were also included.

RESULTS

The review identified several key obstacles, including high costs of transplantation, a limited number of transplant centers, and a critical shortage of skilled healthcare professionals. Cultural beliefs and widespread misconceptions impede organ donation acceptance. Additionally, infectious and non-communicable diseases complicate the transplantation process and outcomes. Weak legal frameworks exacerbate the risks of organ trafficking and unethical practices, while low public awareness further undermines efforts to enhance organ donation rates.

CONCLUSION

Addressing these multifaceted challenges necessitates a comprehensive approach. Strengthening healthcare infrastructure, enhancing capacity-building programs, developing robust legal and ethical frameworks, and implementing targeted public education campaigns are critical for improving organ transplantation in Africa.

Evaluating Challenges in Access To Transplantation for Persons with HIV

PURPOSE OF REVIEW

Antiretroviral therapy has significantly improved the life expectancy of people with HIV (PWH), leading to an increased prevalence of comorbidities such as end-stage organ diseases. PWH with end-stage disease face a significantly higher risk of mortality compared to those without HIV, highlighting the urgent need to improve access to organ transplantation for this vulnerable group. This review examines barriers to organ transplantation for PWH, utilizing a modified five A's model (acceptability, availability, accessibility, affordability, accommodation).

RECENT FINDINGS

Despite comparable post-transplant outcomes to the general population, PWH are less likely to receive organ transplants. The HIV Organ Policy and Equity (HOPE) Act has expanded the donor pool by permitting organ transplants from donors with HIV to recipients with HIV. However, factors limiting expansion include policy, logistical constraints, and HIV-related stigma. Despite pivotal advancements in HIV organ transplantation, multilevel challenges continue to limit access for PWH. Addressing these barriers is essential to ensuring equitable access to this life-saving therapy.

Pharmacotherapeutic Interventions in People Living With HIV Undergoing Solid Organ Transplantation: A Scoping Review

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.

Implications of highly suppressive treatment HIV infection

Treatment of HIV infection has modified the initially fatal infection into a typically chronic disease requiring lifelong treatment. However, there is no complete normalization of immune activation, signs of inflammation and prothrombotic state in treated patients. This condition is the result of many factors, but the main cause is thought to be the residual production of HIV-1 RNA and viral proteins by infected cells in cellular reservoirs. Persistence of immune activation/inflammation/prothrombotic state leads to the pathophysiology of "sterile inflammation" and so-called non-AIDS diseases, which manifest one to two decades earlier in those infected. Despite all the pitfalls and unwanted secondary manifestations of antiretroviral drugs, the treatment of HIV infection has managed to reverse the trajectory of a fatal pandemic and has made it possible to approach therapeutic modalities that were absolutely unimaginable just a few years ago. Solid organ transplantation is now a completely legitimate therapeutic method for patients living with HIV, and highly suppressive treatment even allows transplantation from an HIV-infected donor. The text below presents a brief overview of the basic pitfalls, but also of the successes, of the current highly suppressive treatment of HIV infection.
