Abstract

Background: Inherited bisalbuminemia is rare, mostly benign state, which has so far been described in several pathological conditions. Two genetic variants have already been described in two Croatian families. Herein we report a new case of bisalbuminemia in a Croatian male patient with sarcoidosis.
Methods: The patient was referred by a general practitioner to our hospital for a diagnostic work up for suspected sarcoidosis. Serum capillary protein electrophoresis was performed with automated capillary electrophoresis system.
Results: Based on laboratory and pathologic findings, diagnosis of sarcoidosis was confirmed. Serum electrophoresis revealed two distinct albumin bands. Additional albumin variant was slow-migrating. The slow and a normal band made up for 0.48 and 0.51 of the total albumin, respectively. The patient's sister was also bisalbuminemic.
Conclusions: This is a new case of inherited bisalbuminemia in a patient with sarcoidosis. Whether bisalbuminemia has any relevance to sarcoidosis, remains to be elucidated. Clinical chemists and clinicians should be alerted by every case of either inherited or acquired albumin variant, because it could provide insight into the protein evolution as well as the physical, chemical and molecular characteristics of albumin.
