Introduction: The WaterhouseFriderichsen syndrome is a fulminating infection, often leading to mortality in a matter of hours by producing acute adrenal insufficiency (adrenal hemorrhage) at a time when their response is crucial to address acute stress.
Case report: We present the case of a 4 months boy with high fever 40 °C, vomiting, diarrhea, lethargy, maculopapular rash followed by petechiae and purpura. Biological tests revealed important leukocytosis and thrombocytopenia. Gram staining of cerebrospinal fluid pointed out gram-negative diplococci and latex agglutination testing was positive for type B meningococcal infection. With Glasgow Coma Scale of four the patient was admitted in the Intensive Care Unit and the evolution was positive with biological and clinical resolution after 14 days. ACTH 209 pg/ml (046 pg/ml) and cortisol 4.3 μg/dl (525 μg/dl) outlined the adrenal insufficiency.
Conclusion: Despite the high mortality rate (5560%) our patient survived due to fast and accurate diagnosis. The incidence of WaterhouseFriderichsen syndrome in Romania is 5.88/year/100,000 population aged 02 years, more frequent in countryside area males with poor socio-economically status as our patients case.
Key words: WaterhouseFriderichsen syndrome, meningococcaemia, infant.
