[Fulminant hepatitis in children. Treatment by exchange transfusion].

Fulminant hepatitis is a potentially fatal clinical form of viral hepatitis. The experience at the Infectious Disease Hospital of the I.M.S.S. in Mexico City is presented. Twenty-two children with encephalopathy, grade III or IV managed with exchange transfusion were included. Results between these patients and a similar control group treated conservatively were compared. The mortality rates for the exchange transfusion and the control group were 91 and 100% respectively. A review of the literature revaled great differences in results obtained by several other authors. We conclude that well controled, prospective studies should be done, before the true efficiency of exchange transfusion can be properly evaluated.
