Organ Transplantation and HIV Progress or Success? A Review of Current Status

Transplant advocacy in the era of the human immunodeficiency virus organ policy equity act

In 2013, the Human Immunodeficiency Virus Organ Policy Equity (HOPE) Act was passed to permit the conduct of research on the transplantation of organs from donors infected with human immunodeficiency virus (HIV) into recipients who are HIV-positive. The HOPE Act workshop had many objectives including the discussion of the ethical issues involved in HIV-positive to HIV-positive transplantation, the informed consent process, and the role of independent advocates in the context of HIV to HIV transplantation. As of 2018, 22 transplant hospitals are approved, or undergoing approval, to perform HIV-positive to HIV-positive transplant surgeries, and this number is expected to grow. This study aims to: (i) briefly review the history and research of HIV+ transplantation prior to the HOPE Act, (ii) describe the ethical principles supporting the HOPE Act, (iii) characterize the informed consent process, and (iv) provide guidance regarding the role of independent advocates in the context of HIV-positive to HIV-positive transplantation.

The feasibility of lung transplantation in HIV-seropositive patients

RATIONALE

HIV seropositivity has long been considered a contraindication to lung transplantation, primarily because of the potential risks of added immunosuppression. In the past decade, however, experience with kidney and liver transplantation in the setting of HIV infection, with achievement of satisfactory outcomes, has grown considerably. This promising development has created a need to reconsider this contraindication to lung transplantation.

OBJECTIVES

There is presently limited evidence upon which to base medical decision-making regarding lung transplantation in individuals with HIV infection. In our present study, we wished to extend the existing literature by reporting the outcomes of three individuals with HIV infection who underwent lung transplantation at two centers.

METHODS

We compiled data for a case series of three HIV-infected subjects undergoing lung transplantation at two centers.

MEASUREMENTS AND MAIN RESULTS

We reviewed medical records to investigate the effects of lung transplantation on the course of HIV infection, the development of HIV-related opportunistic infections or malignancies, the occurrence of lung transplant and HIV drug interactions, and the extent of acute rejection. Subject 1, who underwent transplantation for HIV-associated pulmonary arterial hypertension, experienced recalcitrant acute rejection requiring a lymphocyte-depleting agent with subsequent rapid development of bronchiolitis obliterans syndrome. Subjects 2 and 3, who underwent transplantation for idiopathic pulmonary fibrosis, experienced mild acute rejection but remain free from chronic rejection at 4 and 2 years after transplant, respectively.

CONCLUSIONS

Lung transplantation may be feasible for carefully selected patients in the setting of controlled HIV infection. On the basis of our experience with three patients, we caution that acute graft rejection may be more common in such patients.
