Diamond Blackfan Anaemia with Hypothyroidism and CNS Malformations.

ABSTRACT

Diamond Black fan Anemia (DBA) is a congenital erythroid aplasia that usually presents in infancy. The DBA patients have low red blood cell count (Anaemia). The rest of their blood cells (Platelets & WBCs) are normal. We present a 14 month old male child who presented with severe anaemia. The patient was transfusion dependent since 4 months of age. Clinical examination revealed delayed mile stones and a couple of congenital deformities. Haematological parameters showed elevated foetal haemoglobin level (Hb F – 11.8% ) and elevated serum TSH (thyroid stimulating hormone) level. Peripheral blood picture showed gross microcytic hypochromic red blood cells and absence of reticulocytes with normal levels of leucocytes and platelets. A bone marrow showed gross suppression of Erythroid series with ME ratio of 301. Some large pronormoblasts were found. Family history was not significant. Compiling the clinical features, haematological parameters, PS and bone marrow findings, a diagnosis of DBA was given.
