Living-donor lobar lung transplantation (LDLLT) is a viable alternative to deceased-donor lung transplantation in specialized centers under select circumstances. A 47-year-old female underwent LDLLT after nine years of symptomatic scleroderma-associated usual interstitial pneumonia and three years awaiting deceased-donor lung transplantation. Her manifestations of scleroderma included mild sclerodactyly, periungual erythema, Raynaud's phenomenon, and gastroesophageal reflux, with positive antinuclear autoantibodies. Several years post-transplantation, manometry revealed feeble lower esophageal sphincteric pressure with ineffective esophageal motility. Bronchiolitis obliterans syndrome developed 64 months post-transplantation without evidence of aspiration or reflux on transbronchial biopsy. Currently, she has normal renal function and good allogr...

To investigate factors associated with the development of malignancy following transplantation and its effect on survival by retrospectively reviewing a population of lung transplant recipients. Data from 342 consecutive lung transplant patients were collected. Results were analyzed by fitting variables into a multivariate logistic regression model predicting the development of post-transplant malignancies. Covariates were selected based on crude associations that reached a level of significance at P ≤ 0.10. Length of survival was analyzed using the Kaplan-Meier method. Fifty-eight subjects developed post-transplant malignancies, which were the cause of death of 14 patients. Twenty-one patients had a pretransplant malignancy, of whom six developed a malignancy posttransplant--of these, two were fatal recurrences. No risk factors were significantly associated with all forms of post-transpla...

We performed a prospective trial of valganciclovir prophylaxis in lung recipients with outcomes compared to matched historical controls. The valganciclovir group (n = 40) (including D+/R- and R+ patients) was prospectively enrolled, and received oral valganciclovir 900 mg once daily for 12 weeks. Historical controls (n = 40) received 12 weeks of daily intravenous ganciclovir if D+/R- or 12 weeks of oral ganciclovir if R+. CMV viral load testing was done at two-week intervals until 6 months posttransplant. Baseline demographics and immunosuppression were comparable in the two groups. The incidence of CMV viremia was 16/40 (40.0%) in the valganciclovir arm versus 18/40 (45%) in the ganciclovir arm (p = NS). The incidence of symptomatic CMV disease was 8/40 (20%) versus 7/40 (17.5%), respectively (p = NS). In both groups viremia, while on prophylaxis, was uncommon (valganciclovir: 0/40 and ganciclovir: 2/40). Peak viral load and time to viremia were similar in the two arms. High rates of viremia and symptomatic disease occurred in the D+/R- patients after discontinuation of prophylaxis. Genotypic CMV sequence analysis demonstrated low rates of ganciclovir resistance in both groups. Valganciclovir prophylaxis had similar efficacy to either intravenous ganciclovir (D+/R- patients), or oral ganciclovir (R+ patients) in lung recipients.
