[Ketoacidosis coma auguring diabetes in black adults].

A particular form revealing diabetes mellitus in the black race is described: adult's inaugural ketoacidosis requiring a temporary insulin treatment, followed by a variable remission stage. We present in this work the clinical and evolutive characters of this coma inaugurating diabetes mellitus from twenty seven (27) patients of the metabolic diseases departement (CHU-Brazzaville). Among adult patients presenting a ketoacidosis coma, the prevalence rate of inaugural form is forty two percent (42%).
