Coma Mixedematoso

Os AA. apresentam 5 casos de coma mixedematoso observados no período de 1984 a 1992. Trata-se de 4 doentes do sexo feminino e 1 do sexo masculino com idades compreendidas entre os 45 e 73 anos. Em 3 doentes não havia diagnóstico prévio de hipotiroidismo. A depressão do estado de consciência, a hipotermia, a bradicardia e a ausência de bócio eram comuns aos 5 doentes. Foi identificado factor desencadeante em 3 deles. Utilizada levotiroxina e/ou liotironina por via oral, hidrocortisona e medidas de suporte, a evolução foi favorável nos 2 doentes em que tinha sido identificado factor desencadeante, que apresentavam menor depressão do S.N.C. e normalização da temperatura corporal ao 3° dia de terapêutica.

Fulminant Hepatitis E in a Pregnant Woman

Hepatitis E is an inflammatory liver disease caused by hepatitis E virus (HEV) infection, which is endemic in China, India, Nepal, and in several Asian and African countries, where the prevalence can be as high as 50%. In non-endemic countries, an increasing number of non-travel associated HEV has been reported in recent years, particularly in Europe. The authors describe the clinical case of a puerperal 24-year-old woman from Pakistan admitted to our Tertiary Care Medical Center with acute hepatic failure developed during the third trimester of her pregnancy. She was icteric with grade III encephalopathy and hypothermia. Laboratory values showed significant AST, ALT and LDH elevations of twelve times the upper normal limit, and total bilirubin was significantly elevated (41.20 mg/dL). Prothrombin time was prolonged (4 s) and factor V activity was diminished (15.1%). Extracorporeal albumin dialysis was initiated, but clinical deterioration occurred within 48 h, so she underwent OLT at day 4 post-admission. Severe forms of HEV are known to be more pronounced in pregnant women. Even though most of the described cases of acute hepatic failure associated to HEV during pregnancy had a favorable clinical course, some cases of fulminant liver failure and death are described. It is unknown whether liver transplant outcomes in this setting are different from other causes of acute liver failure. To our knowledge, this is the first case report in Portugal from a pregnant woman who developed hepatic failure due to fulminant hepatitis E that underwent successful liver transplantation.
