Febre Escaro-Nodular: Revisão Retrospetiva de Casos Hospitalizados e Fatores Preditores de Doença Severa

Abstract

Results:We reviewed 71 cases of Mediterranean spotted fever. The mean age was 63.3 ± 16.7 years and 52.1% were male. The eschar was observed in 62.0%. Fever and rash were the most common clinical findings. Forty five percent of patients developed complications and 22.5% were admitted to intermediate and/or intensive care units. Apyrexia, dyspnea, renal failure and elevated lactic dehydrogenase levels at admission were predictors of severe disease development (p < 0.034). Alcoholism was related with prolonged hospitalization (p = 0.020). Absence of fever (p = 0.019) and elevated serum creatinine levels (p = 0.028) were identified as independent factors associated with severe outcome. The mortality rate was 2.8%. Discussion: Although Mediterranean spotted fever is usually assumed to be benign, severe cases are emerging. Conclusion: Early identification of the infection and continuous patient surveillance are crucial, particularly in those with greater risk of developing severe or fatal disease.
