[Acute drug-induced agranulocytosis. Clinical study apropos of 30 patients and evolution of etiologies over 2 decades].
Between 1982 and 1993, 30 patients were treated for drug-induced agranulocytosis. They did not receive cytotoxic chemotherapy nor radiotherapy during the past 6 months. There is a higher incidence in women (21 females, nine males). Mean age is 59.3 years old. The drug could be found in 25 cases including noramidopyrine five cases, antithyroid drugs four cases, non steroidal anti-inflammatories drugs four cases. Five patients died of infection during agrulocytosis. Sepsis was documented in three cases. We used hematopoietic growth factors in two cases. Neutrophils rose up to 0.5.10(9)/l between 2 to 14 days after the diagnosis and 1.10(9)/l between 3 to 16 days. Time when absolute neutrophil count was less than 0.5.10(9)/l was shorter (p = 0.008) when bone marrow was rich with maturation arrest but with few or no mature forms rather than reduction of granulocytic precursors. By comparison with a similar study made in the same institution between 1971 and 1981, there were fewer cases each year. Drugs involved were not similar: phenicols were not found, reference to noramidopyrine is less frequent. Now antithyroid drugs is becoming one of the most important etiologies.
