[Hyperlipoproteinemias in diabetes mellitus]

Among 200 diabetics 63 patients (31.5%) with primary and 44 patients (22%) with secondary hyperlipoproteinaemias were found. The secondary hyperlipoproteinaemias belonged to the types IV and V, the primary hyperkipoproteinaemias to the types IIa, IIb, IV and V. In primary hypercholesterolaemias (IIa, IIb) the retinopathia diabetica by far more frequently occurs than in primary hypertriglyceridaemias.
