Safe pregnancy after liver transplantation: Evidence from a multicenter Italian collaborative study.

BACKGROUND: Women who have undergone liver transplantation (LT) enjoy better health, and possibility of childbearing. However, maternal and graft risks, optimal immunosuppression, and fetal outcome is still to clarify. AIM: Aim of the study was to assess outcomes of pregnancy after LT at national level. METHODS: In 2019, under the auspices of the Permanent Transplant Committee of the Italian Association for the Study of the Liver, a multicenter survey including 14 Italian LT-centers was conducted aiming at evaluating the outcomes of recipients and newborns, and graft injury/function parameters during pregnancy in LT-recipients. RESULTS: Sixty-two pregnancies occurred in 60 LT-recipients between 1990 and 2018. Median age at the time of pregnancy was 31-years and median time from transplantation to conception was 8-years. During pregnancy, 4 recipients experienced maternal complications with hospital admission. Live-birth-rate was 100%. Prematurity occurred in 25/62 newborns, and 8/62 newborns had low-birth-weight. Cyclosporine was used in 16 and Tacrolimus in 37 pregnancies, with no different maternal or newborn outcomes. Low-birth-weight was correlated to high values of AST, ALT and GGT. CONCLUSION: Pregnancy after LT has good outcome; however, maternal complications and prematurity may occur. Compliance with the immunosuppression is fundamental to ensure the stability of graft function and prevent graft-deterioration.

Neuropsychiatric performance and treatment of hepatitis C with direct-acting antivirals: a prospective study.

BACKGROUND: Since direct-acting antivirals (DAAs) have been approved for the treatment of hepatitis C virus (HCV) infection, a small series of patients with new-onset neuropsychiatric alterations have been referred to us. We therefore set out to study neuropsychiatric function in relation to DAAs prospectively. METHODS: Ten patients with cirrhosis and 12 post-liver transplant (post-LT) patients were enrolled. All underwent wake electroencephalography (EEG) and a neuropsychological evaluation (paper and pencil battery, simple/choice reaction times, working memory task) at baseline, at the end of treatment with DAAs and after 6 months. At the same time points, full blood count, liver/kidney function tests, quantitative HCV RNA, ammonia and immunosuppressant drug levels were obtained, as appropriate. RESULTS: Patients with cirrhosis were significantly older than post-LT patients (65±12 vs 55±7 years; P<0.05). Neuropsychological performance and wake EEG were comparable in the two groups at baseline. At the end of a course of treatment with DAAs, a significant slowing in choice reaction times and in the EEG (increased relative delta power) was observed in patients with cirrhosis, which resolved after 6 months. In contrast, no significant changes over time were observed in the neuropsychiatric performance of post-LT patients. No significant associations were observed between neuropsychiatric performance and stand-alone/combined laboratory variables. CONCLUSION: Some degree of neuropsychiatric impairment was observed in relation to treatment with DAAs in patients with cirrhosis, but not in post-LT patients, suggesting that the former may be sensitive to mild DAA neurotoxicity.
