Medication misuse, nonadherence, and clinical outcomes among liver transplant recipients.

ABSTRACT: Medication nonadherence after liver transplantation (LT) is associated with adverse clinical outcomes such as graft rejection and graft loss. Few studies have examined nonadherence and its impact on clinical outcomes in LT. The study objectives were (1) to evaluate medication understanding (with treatment knowledge and demonstrated regimen use scores) and medication adherence or nonadherence to entire regimens among LT recipients and (2) to examine associations of these exposures with clinical outcomes. We conducted a 2-site study of 105 recipients between 2011 and 2012 at 2 transplant centers in Chicago, IL and Atlanta, GA. Data were collected via detailed, in-person interviews and medical record reviews. Study participants were middle-aged and predominantly male; 15% of the sample had limited literacy. On average, patients were taking 11 medications [standard deviation (SD)?=?4], and 39% had undergone a medication change within the last month. The average scores for the entire medication regimen were 86% (SD?=?22%) for treatment knowledge and 78% (SD?=?22%) for demonstrated regimen use. The mean score for self-reported nonadherence to the entire regimen was 14% (SD?=?20%), whereas 32% of the patients were nonadherent according to tacrolimus levels. In multivariate analyses, lower income, less time since transplantation, a higher number of medications, and limited literacy were inversely associated with treatment knowledge scores (all P?

Project description:Influenza is a common respiratory tract infection in solid organ transplant (SOT) recipients. We aimed to investigate the incidence, risk factors, and complications of influenza in a large cohort of kidney and liver transplant recipients over 10 consecutive seasons. We conducted a retrospective study, including 378 liver and 683 kidney transplant recipients who were transplanted from January 1, 2010, to October 1, 2019. The data on influenza were retrieved from MiBa, which is a nationwide database that contains all of the microbiology results in Denmark. Clinical data were retrieved from patient records. Incidence rates and cumulative incidences were calculated, and risk factors were investigated using time-updated Cox proportional hazards models. The cumulative incidence of influenza in the first 5 years posttransplantation was 6.3% (95% CI: 4.7 to 7.9%). Of the 84 influenza positive recipients, 63.1% had influenza A, 65.5% were treated with oseltamivir, 65.5% were hospitalized, and 16.7% developed pneumonia. There were no significant differences in outcomes when comparing patients with influenza A and B. We found no significant effect of same-season influenza vaccination, sex, age, or comorbidities on the risk of acquiring influenza. The incidence of influenza in kidney and liver recipients is high, and 65.5% of infected transplant recipients required hospitalization. We were not able to confirm a reduction in influenza incidence or in the risk of complications associated with vaccination. IMPORTANCE Influenza is a common respiratory virus in solid organ transplant recipients that may have severe complications, including pneumonia and hospitalization. This study investigates the incidence, risk factors, and complications of influenza in a Danish cohort of kidney and liver transplant recipients over 10 consecutive influenza seasons. The study shows a high incidence of influenza and a high frequency of both pneumonia and hospitalization. This emphasizes the importance of continuous focus on influenza in this vulnerable group. During the COVID-19 pandemic, the incidence of influenza has been low due to COVID-related restrictions, and immunity may have waned. However, as most countries have now opened up, the incidence of influenza is expected to be high this season.

Project description:BackgroundSuccessful lung transplantation for patients with pulmonary fibrosis from telomerase mutations may be limited by systemic complications of telomerase dysfunction, including myelosuppression, cirrhosis, and malignancy. We describe clinical outcomes in 14 lung transplant recipients with telomerase mutations.MethodsSubjects underwent lung transplantation between February 2005 and April 2014 at 5 transplant centers. Data were abstracted from medical records, focusing on outcomes reflecting post-transplant treatment effects likely to be complicated by telomerase mutations.ResultsThe median age of subjects was 60.5 years (interquartile range = 52.0-62.0), 64.3% were male, and the mean post-transplant observation time was 3.2 years (SD ± 2.9). A mutation in telomerase reverse transcriptase was present in 11 subjects, a telomerase RNA component mutation was present in 2 subjects, and an uncharacterized mutation was present in 1 subject. After lung transplantation, 10 subjects were leukopenic and 5 did not tolerate lymphocyte anti-proliferative agents. Six subjects developed recurrent lower respiratory tract infections, 7 developed acute cellular rejection (A1), and 4 developed chronic lung allograft dysfunction. Eight subjects developed at least 1 episode of acute renal failure and 10 developed chronic renal insufficiency. In addition, 3 subjects developed cancer. No subjects had cirrhosis. At data censorship, 13 subjects were alive.ConclusionsThe clinical course for lung transplant recipients with telomerase mutations is complicated by renal disease, leukopenia with intolerance of lymphocyte anti-proliferative agents, and recurrent lower respiratory tract infections. In contrast, cirrhosis was absent, acute cellular rejection was mild, and development of chronic lung allograft dysfunction was comparable to other lung transplant recipients. Although it poses challenges, lung transplantation may be feasible for patients with pulmonary fibrosis from telomerase mutations.
