[A case of analbuminaemia (author's transl)].

A new case of analbuminaemia is described in a 6 month old child of algerian origin. The condition was discovered fortuitously, the clinical manifestations consisting only of slight oedema. Serum albumin concentration was 64 mg/l and its immunochemical behavior identical to that of normal albumin. The body react by an increase in the synthesis of globulins. In the propositus, levels of alpha, antitrypsin, caeruloplasmin, haptoglobin, jalpha2 macroglobulin, transferrin, immunoglobulin M were more than 3 times normal. Analysis of non-esterified fatty acids normally carried by albumin was normal. By contrast, it was shown that the presence of free bilirubin not bound to proteins was detected from 17 micronmol/l. Study of the family showed a normal distribution of albumin and globulins. The genetic origin seen in previously reported cases was confirmed by the co-sanguinity of the parents.
