Lung Transplantation for People Living With HIV: Promising Mid-term Outcomes.

BACKGROUND: With increasing life expectancy, patients with HIV are more commonly acquiring other chronic diseases, such as end-stage lung disease, for which transplant may be the only effective solution. Until recently, HIV infection was considered a contraindication to lung transplant (LTx). As LTx in people living with HIV (PLWH) becomes more common, there remain limited data on outcomes in this population. METHODS: Using the Organ Procurement and Transplantation Network Standard Transplant Analysis and Research file, we identified LTx recipients with HIV by either serostatus or nucleic acid testing. A control group of confirmed HIV-negative LTx recipients was propensity score matched on age, body mass index, primary diagnosis, and year of transplant. Patient characteristics, transplant parameters, survival, and postoperative outcomes were compared. RESULTS: Fifty-nine LTx recipients with HIV were identified and compared with 236 HIV-negative controls. Among PLWH, cytomegalovirus status was more frequently positive (76.3% versus 58.9%, P = 0.014), and the median Lung Allocation Score at match was higher (44 versus 39, P = 0.004). PLWH were more likely to undergo dialysis postoperatively (18.6% versus 8.9%, P = 0.033), although other complication rates were similar. Fifty-three percent of LTx for PLWH occurred since 2020. One-year survival for PLWH was 91.2% versus 88.6% for controls ( P = 0.620). Three-year survival for a smaller subset was also not statistically significant (HIV versus control: 82.6% versus 77.8%, respectively, P = 0.687). CONCLUSIONS: There was no difference in 1-y survival for LTx recipients living with HIV compared with a matched control group, supporting this group of patients as viable candidates for LTx.

Hyperthermic intrapleural chemotherapy: an update.

The safety and efficacy of hyperthermic intrathoracic chemotherapy (HITHOC) as an adjunct to cytoreductive surgery (CRS) in pleural malignancies has been well demonstrated. This is most often described in cases of mesothelioma, thymoma, or other secondary pleural metastases. The utilization of a direct cytotoxic agent with increased penetration secondary to a hyperthermic environment is especially beneficial in pleural malignancy as a microscopic resection remains immensely challenging. Despite favorable outcomes with a limited associated risk profile, there persists a variety in utilization and technique of HITHOC described in current literature. National Comprehensive Cancer Network (NCCN) guidelines state that though intraoperative adjuvant therapies such as HITHOC have been studied, they remain of unclear benefit and definitive recommendations do not currently exist. This ambiguity limits the standardization of HITHOC, thus hindering its further application in a patient population with exceedingly poor outcomes within current guideline-based therapy. As the prevalence of pleural malignancies necessitating CRS with adjuvant HITHOC remains quite low, we believe a task force initiative to further investigate the role of HITHOC in surgical management of pleural malignancies would enable wider utility of this promising technique. Additionally, we propose that the creation of a pleural cancer index could aid in standardization of HITHOC in those with pleural malignancy.
