[Primary distal renal tubular acidosis coexisting with malabsorption syndrome]

The authors present the case of 54-old man primary tubular acidosis coexisting with malabsorption syndrome. Deviation were: extension of QT interval, low level of potassium and calcium in the blood, perturbations of calcium metabolism and high level of PTH. Glucose, lactose and iron absorption curves were flat. The final diagnosis was given as a result of analysis of findings and literature. The patient underwent the vitamin D3, calcium and potassium preparations, hydrochlorotiazyd treatment. Megaloblastic anaemia was treated with vitamin B12 and folic acid. Such therapy gave considerable improvement in patient's general condition and normalisation of lab tests results. The authors try explain the etiopathogenesis of bones changes and high level of parathormone. They assume the attitude towards methods of therapy and necessary medicaments doses. Relationship between described syndromes remains inextricable. Roentgen image of ileum which suggests occlusion is still unexplainable. Described case seemed to be very interesting considering rarity of primary tubular acidosis and its coexistence with malabsorption syndrome.
