[Mushroom poisoning with a long period of development]

A group of 87 patients with the signs of poisoning with mushrooms with along period of incubation (t = 12.4 +/- 6.2 h) has been reported. Nausea, vomiting and diarrhea dominate in the clinical picture in the first phase and hepatic and/or renal insufficiency in the second phase. Forty-one patients (47.1%) had "only" clinical symptoms without severe parenchymatous impairments. Forty-six (54.9%) had evidence of a hepatic lesion and 8 patients (10.8%) had renal function impaired, 6 of which needed hemodialysis. There was a significant correlation between elevation of serum transaminases and prolongation of prothrombin complex, resulting from the decreased synthetic liver function (SGPT1/PV1r = -0.424, p = 0.00; SGOT1/PV1r = -0.448, p = 0.000) during the first days after poisoning. Hepatic and renal damage was not identical in all the cases, and there was no correlation between the elevation of serum transaminases and retention of nitrogen substances. When analysing the effect of therapy on elevation of serum transaminases and prolongation of prothrombin complex, a significant difference between elevation of serum transaminases and prolongation of prothrombin time was found in patients on competitive inhibition with penicillin or silibinin, as compared to the patients only on plasmapheresis (p = 0.004 for SGOT, p = 0.000 for SGPT). These data unquestionably suggest the efficacy of competitive inhibition in the treatment of poisoning with mushrooms of a long period of incubation. In favour of this therapy also speaks the group of seriously ill patients who were simultaneously on plasmapheresis and competitive inhibition and who had better improvement than those "only" on plasmapheresis (p = 0.004 for SGOT).(ABSTRACT TRUNCATED AT 250 WORDS)
