    Posttransplant Pneumonia Among Solid Organ Transplant Recipients Followed in Intensive Care Unit
    (2022) Yesiler, Fatma Irem; Yazar, Cagla; Sahinturk, Helin; Zeyneloglu, Pinar; Haberal, Mehmet; 0000-0002-3887-0314; 0000-0003-0159-4771; 0000-0002-3462-7632; 34269656; AAJ-1419-2021; AAJ-8097-2021
    Objectives: Pneumonia is a significant cause of morbidity and mortality in solid-organ transplant recipients. We studied the demographic characteristics, respiratory management, and outcomes of solid-organ transplant recipients with pneumonia in an intensive care unit. Materials and Methods: There have been 2857 kidney, 687 liver, and 142 heart transplants performed between October 16, 1985, and February 28, 2021, at our center. We retrospectively analyzed records for 51 of 193 recipients with pneumonia during the posttransplant period between January 1, 2016, and December 31, 2018. Results: Fifty-one of 193 recipients were followed in the intensive care unit. Mean age was 45.4 +/- 16.6 years among 42 male (82.4%) and 9 female (17.6%) recipients. Twenty-six patients (51%) underwent kidney transplant, 14 (27.5%) liver transplant, 7 (13.7%) heart transplant, and 4 (7.8%) combined kidney and liver transplant. Most pneumonia episodes occurred 6 months after transplant (70.6%) with acute hypoxemic respiratory failure. Mean Acute Physiology and Chronic Health Evaluation System II score was 18.9 +/- 7.7, and the Sequential Organ Failure Assessment score was 8.5 +/- 3.9 at intensive care unit admission. Whereas 66.7% of pneumonia cases were nosocomial acquired, 33.3% were community acquired. The intensive care unit and 28-day mortality rates were 39.2% and 64.7%, respectively. Conclusions: Solid-organ transplant recipients with pneumonia have been associated with poor prognosis. Our cohort followed in the intensive care unit comprised mostly patients with nosocomial pneumonia with acute hypoxemic respiratory failure, hospitalized 6 months after transplant with high Acute Physiology and Chronic Health Evaluation System II scores predictive of mortality. In this high-risk patient group, careful follow-up, early discovery of warning signs, and rapid treatment initiation could improve the outcomes in the intensive care unit.

    Treatment of Posttransplant Hepatocellular Carcinoma Recurrence
    (2022) Haberal, Mehmet; Karakaya, Emre; Akdur, Aydincan; Soy, Ebru Ayvazoglu; https://orcid.org/0000-0002-3462-7632; https://orcid.org/0000-0002-8726-3369; https://orcid.org/0000-0002-0993-9917; 35060449; AAJ-8097-2021; AAA-3068-2021; AAC-5566-2019
    Objectives: In patients who receive liver transplant to treat hepatocellular carcinoma, 10% to 15% posttransplant recurrence is observed. In the present study, we evaluated the long-term outcomes of patients who had received liver transplant for treatment of hepatocellular carcinoma. Materials and Methods: Of the 683 liver transplants that we performed, 72 were in response to hepatocellular carcinoma. The physical examination and laboratory and imaging results of the patients were retrospectively analyzed and recorded. The recipients were evaluated according to the Baskent criteria and divided into 2 groups: early diagnosis and late diagnosis. Results: Among 72 total patients in our study, 19 (26.3%) were pediatric recipients. Hepatocellular carcinoma recurred in 7 patients (9.7%; 5 adult, 2 pediatric). Except for one patient, all were in the late diagnosis group.The mean survival time of all patients was 137.45 +/- 10 months.The mean survival in the early diagnosis group was longer than in the late diagnosis group. During follow-up, 11 patients died from recurrence and distant metastasis. Conclusions: In patients with hepatocellular carcinoma who received liver transplant, we found that postoperative recurrence of hepatocellular carcinoma and distant metastasis can be treated with surgery and/or with interventional radiology methods, which may improve patient survival after liver transplant.
