[A patient with type ZZ alpha 1-antitrypsin deficiency and hypercalcemia caused by sarcoidosis].

The history of illness of an eight-year-old boy is presented. Fifteen days old he had been hospitalized because of vomiting, diarrhoea and prolonged jaundice. Alpha 1-antitrypsin deficiency (genotype PiZZ) was diagnosed. At the age of nearly eight complaints started, such as headache, apathy, nausea and vomiting. Sarcoidosis was diagnosed on account of hypercalcemia (3.48-3.68 mmol/l), an elevated serum angiotensin converting enzyme (60 U/l), a positive Kveim test and the fact that other diseases could be excluded. The prognosis of a combination of a serious alpha 1-antitrypsin deficiency and sarcoidosis is discussed. This combination, as far as we have been able to trace, has not been described before.
