Abstract The prognostic value of 36 clinical and analytical parameters at diagnosis in patients with drug-induced agranulocytosis was analysed in an adult population. This multicentre, retrospective study examined possible prognostic factors by multiple logistic regression analysis in a series of 168 clinical episodes. The overall mortality was 16\%. Renal insufficiency at diagnosis and the development of bacteraemia were associated with a poor prognosis. Advanced age, decreased leucocyte count, lymphocytopenia, bone marrow myeloid hypoplasia, increased percentage of bone marrow plasma cells and shock were found to be associated with a poor prognosis only in the univariate analysis. An independent analysis of the myeloid cellularity at diagnosis showed an inverse correlation with the time to recovery of the granulocyte counts (r = -0.43; P = 0.001). Our data indicate that despite some important clinical differences (higher incidence of infections of the oropharynx, shorter period of neutropenia and almost exclusive presence of gram-negative organisms), the infections complicating the treatment of cancer patients have the same prognostic features than those seen in patients with acute agranulocytosis. Therefore the established therapeutic guidelines for neutropenia after cancer chemotherapeutic agents are applicable to patients with acute agranulocytosis.
