The incidence of severe falciparum malaria is increasing in the developed countries and mortality remains high despite progress in intensive care management and schizonticide treatment. Many authors emphasize the importance of exchange transfusion (EXT) in the most severe cases. We studied 21 cases (34 +/- 12 years, 6 females; SAPS: 8.4 +/- 3.7) of severe malaria (according to WHO criteria) consecutively admitted to ICU between 1985 and 1990: 3 patients underwent EXT. Twenty were febrile above 39 degrees C, 10 had cerebral malaria, 14 hepatic impairment, 8 acute renal failure, 5 pulmonary oedema. Nine patients required mechanical ventilation, 1 haemodialysis, 1 intracranial pressure monitoring. Mean parasitemia was 13%, 16 patients had thrombocytopenia less than 50 x 10(9)/l, 3 anemia less than 7 g/dl and 3 leucopenia less than 2.8 x 10(9)/l. Nineteen received quinine i.v., 1 mefloquine, 1 chloroquine. Sixteen patients received blood products transfusion, 3 were treated by EXT in addition. Twenty were cured and discharged from hospital without sequelae (mean stay: 14 days); 4 had nosocomial infection, 1 a splenic infarction. One patient (17-years-old; SAPS: 17; parasitemia: 7.8%) died 12 h after admission from non-cardiogenic pulmonary oedema with multi-organ failure. The literature and this study lead us to propose EXT in patients with unfavourable evolution after conventional treatment rather than in all the patients with a parasitemia above 10% at admission. A randomized study to compare conventional treatment in ICU with or without EXT is necessary.

The aim of this retrospective descriptive study was to describe both epidemiologically and clinically manifestations following severe scorpion envenomation and to define simple predictive factors which can be used in routine practice in general Intensive Care Units (ICU) as an indicator of poor prognosis. Cases were collected from hospital patients' files during 13-year (1990-2002) period in the medical Intensive Care Unit of a university hospital (Sfax - Tunisia). The diagnosis of scorpion envenomation was based on a history of scorpion sting. Nine hundred fifty-one patients, who were admitted for a scorpion sting, were analyzed. There were 769 patients (80.8%) in the grade III group (with cardiogenic shock and/or pulmonary edema or severe neurological manifestation (coma and/or convulsion)) and 182 patients (19.2%) in the grade II group (with systemic manifestations). Scorpion envenomation is more frequent in summer; indeed 82.3% of our patients were admitted between June and September. The mean age (+/-SD) was 14.7 +/- 17.4 years, ranging from 0.5 to 90 years. In this study 739 patients (77.8%) had neuromuscular signs, 700 patients (73.6%) had gastrointestinal signs and 585 patients (61.5%) had a pulmonary edema, while 195 patients (20.5%) had a cardiogenic shock. The mean blood sugar on admission was at 11.32 +/- 5.66 mmol/l, a high blood sugar level (>11 mmol/l) was observed in 39% of cases. The mean blood urea was at 7.1 +/- 3.2 mmol/l, it was above 10 mmol/l in 10.7% of cases. The mean of leucocytes was at 17 418 +/- 7833 cells/mm(3), it was above 11 000/mm(3) in 80% of cases. In the end of the stay in ICU, evolution was marked by the improvement of 879 patients (92.5%) while 72 patients (7.5%) died. A multivariate analysis found the following factors to be correlated with a poor outcome: age less than 5 years (OR = 2.27), fever >38.5 degrees C (OR = 2.79), coma with Glasgow coma score < or =8/15 (OR = 9.87), pulmonary edema (OR = 8.46), leucocytes >25 000 cells/mm3 (OR = 2.35) and blood urea >8 mmol/l (OR = 4.02). Moreover, in children group, a significant association was found between PRISM score and mortality rate, this model had a high discriminative power with an area under the ROC curve at 0.93. In the adult patients a significant association was found between SAPS II score and mortality rate, this model had a high discriminative power with an area under the ROC curve at 0.82. In summary, in severe scorpion envenomation, age less than 5 years, fever >38.5 degrees C, coma with Glasgow coma score < or =8/15, pulmonary edema, leucocytes >25 000 cells/mm3 and blood urea >8 mmol/l were associated with a poor outcome.
