ABSTRACT
Nineteen Arab children including six boys and 13 girls in ten sibships were diagnosed as having osteopetrosis over a 5-year period in various hospitals in Kuwait. Eighteen patients had an isolated autosomal recessive form and one had autosomal recessive osteopetrosis associated with renal tubular acidosis. The mean age of diagnosis was 24 months. Parental consanguinity was high amongst them (68%). Anaemia, hepatosplenomegaly, failure to thrive, recurrent infections and neurological manifestations were common. Associated congenital abnormalities were found in 26%. Deafness, hydrocephalus and dental caries were relatively less common. A high mortality (37%) owing to infection was noted. The medical management and recommendations for patient care are discussed briefly.
