Fulminant hepatic failure: a Portuguese experience

BACKGROUND: Fulminant hepatic failure (FHF) is a rare condition. Several series have been reported either by individual centres or in multicentre studies but, to our knowledge, this is the first report from a Portuguese population and might be a good example of FHF cases in a SouthWestern European population. AIMS: To present the experience in FHF of a Portuguese Hepatogastroenterological Intensive Care Unit. MATERIALS AND METHODS: Retrospective study of 61 cases of FHF consecutively admitted between February 1992 and October 2006. Definition and classification of FHF were those suggested by Trey and Davidson (1970) and O'Grady et al. (1993), respectively. Criteria and contraindications for hepatic transplantation (HT) were those proposed by Bernuau et al. (1991) and Muñoz (1993), respectively. RESULTS: Fifty-seven per cent of patients were women and median age was 37 years (range: 8-73). Most common cause of FHF was indeterminate (26%) followed by viral (23%) and drug-induced (23%), with 51% of cases with a hyperacute evolution. Global HT rate was 54% with criteria for HT present in 87% of the patients resulting in an applicability rate of 62%. Overall survival was 69% and transplant-free survival was 15%; transplanted patients had survival rates of 70 and 68% at 6 and 12 months, respectively. CONCLUSIONS: Drug-induced and viral agents were responsible for almost half of FHF cases with a clear predominance of hyperacute presentation. The HT rate was 54% and the applicability rate was 62%. The overall 1 year survival of 69% might reflect the adequacy of the HT criteria used.

Gender mismatch between donor and recipient is a factor of morbidity but does not condition survival after cardiac transplantation

We intended to evaluate the influence of sex mismatch between donor and recipient, which is still under much debate, on survival and comorbidities after cardiac transplantation. From November 2003 to December 2013, a total of 258 patients were transplanted in our center. From these, 200 receptors were male (77.5%) and constituted our study population, further divided into those who received the heart from a female donor (Group A) - 44 patients (22%) and those who received it from a male donor (Group B) - 156 (78%). Median follow-up was 4.2 ± 3.0 years (1-10 years). The two groups were quite comparable with each other, except for body mass index, systolic pulmonary artery pressure, and transpulmonary gradient, which were significantly lower in Group A. A low donor/recipient weigh ratio (<0.8) was avoided whenever possible. Hospital mortality was not different in the two groups. During follow-up, global survival was similar, as was survival free from acute cellular rejection and cardiac allograft vasculopathy. However, patients in Group A had decreased survival free from serious infections and malignant tumors. Allocation of female donors to male receptors can be done safely, at least in receptors without pulmonary hypertension and when an adequate donor/recipient weigh ratio is ensured.
