Correlates and outcomes of alcohol use after single solid organ transplantation: A systematic review and meta-analysis.

BACKGROUND: Reviews on alcohol use in transplant recipients focus on liver recipients and their risk of post-transplant rejection, but do not assess alcohol use in kidney, heart, or lung transplant recipients. This systematic review and meta-analysis aims to synthesize the evidence on correlates and outcomes of any alcohol use and at-risk drinking after solid organ transplantation (Tx). METHODS: We searched 4 databases for quantitative studies in adult heart, liver, kidney and lung Tx recipients, investigating associations between post-Tx alcohol use and correlates and/or clinical, economic or quality of life outcomes. Paper selection, data extraction and quality assessment were performed by 2 reviewers independently. A pooled odds ratio (OR) was computed for each correlate/outcome reported ≥5 times. RESULTS: Of the 5331 studies identified, 76 were included in this systematic review (93.3% on liver Tx; mean sample size 148.9 (SD = 160.2); 71.9% male; mean age 48.9 years (SD = 6.5); mean time post-Tx 57.7 months (SD = 23.1)). On average, 23.6% of patients studied used alcohol post-transplant. Ninety-three correlates of any post-Tx alcohol use were identified, and 9 of the 19 pooled ORs were significantly associated with a higher odds for any post-Tx alcohol use: male gender, being employed post-transplant, smoking pre-transplant, smoking post-transplant, a history of illicit drug use, having first-degree relatives who have alcohol-related problems, sobriety <6 months prior to transplant, a history of psychiatric illness, and having received treatment for alcohol-related problems pre-transplant. On average 15.1% of patients had at-risk drinking. A pooled OR was calculated for 6 of the 47 correlates of post-Tx at risk drinking investigated, of which pre-transplant smoking was the only correlate being significantly associated with this behavior. None of the outcomes investigated were significantly associated with any use or at-risk drinking. CONCLUSION: Correlates of alcohol use remain under-investigated in solid organ transplant recipients other than liver transplantation. Further research is needed to determine whether any alcohol use or at-risk drinking is associated with poorer post-transplant outcomes. Our meta-analysis highlights avenues for future research of higher methodological quality and improved clinical care. PROTOCOL REGISTRATION: PROSPERO protocol CRD42015003333.

A prospective cohort study on posttraumatic stress disorder in liver transplantation recipients before and after transplantation: Prevalence, symptom occurrence, and intrusive memories.

OBJECTIVE: This study aimed at increasing the understanding of posttraumatic stress disorder (PTSD) in liver transplant patients by describing the course of PTSD, symptom occurrence, psychological co-morbidity, and the nature of re-experiencing symptoms. METHODS: A prospective cohort study was performed among 95 liver transplant recipients from before transplantation up until one year post-transplantation. Respondents filled out a questionnaire regarding psychological functioning (PTSD, anxiety, and depression) before, and at 3, 6, and 12months post-transplantation. Both quantitative and qualitative methods were used to analyze the data. RESULTS: Before transplantation, respectively 10.5% and 6.3% of the respondents were identified as possible cases of full or partial PTSD. In all cases, co-morbid conditions of anxiety and/or depression were present. After transplantation, no new onset of full PTSD was found. New onset of possible partial PTSD was found in six respondents. Arousal symptoms were the most frequently reported symptoms, but may not be distinctive for PTSD in transplant patients because of the overlap with disease- and treatment-related symptoms. Re-experiencing symptoms before transplantation were mostly related to waiting for a donor organ and the upcoming surgery; after transplantation this was related to aspects of the hospital stay. CONCLUSIONS: In our group of liver transplant patients, PTSD symptomatology was more present before transplantation than after transplantation. Being diagnosed with a life-threatening disease seemed to be the main stressor. However, when a diagnosis of PTSD is suspected, assessment by a clinician is warranted because of the overlap with mood and anxiety disorders, and disease- and treatment-related symptoms.

Quality of life in patients with familial amyloidotic polyneuropathy long-term after liver transplantation.

Liver transplantation aims to halt the progression of the disease in patients with familial amyloidotic polyneuropathy (FAP) caused by hereditary transthyretin-related (ATTR) amyloidosis. Insight in health-related quality of life of these transplanted FAP-patients can be of help to optimize health care delivery. The aim of this cross-sectional study was to assess the health-related quality of life of patients with FAP long-term after transplantation. Nine patients with a post-transplant follow-up of 4 years or more were included in the study. During the annual checks, health-related quality of life was measured with the Short Form-36 (SF-36). Data were compared with non-FAP transplanted patients with the same duration of follow-up and with the normal Dutch population. Pre-transplant, all patients had signs of mild to moderate peripheral polyneuropathy. The results showed that in patients with FAP health-related quality of life was stable in the first 4 years after transplantation. The domain of physical well-being at 4 years after transplantation was significantly lower compared to non-FAP transplanted patients and control Dutch population. The domain of emotional well-being was comparable with non-FAP controls. However, on most health areas patients with FAP scored lower than the non-FAP transplanted patients and the Dutch controls. After four years, the three patients with FAP with longest follow-up (9-12 years) deteriorated in all health domains, except in self-perceived mental health. This study, including only a small number of patients with FAP, shows a relatively low health-related quality of life after liver transplantation, which may deteriorate further with longer follow-up.
