Severe combined immunodeficiency in a Malaysian child

A 3-month-old Malay male infant presented with multiple infections (candidiasis, Pseudomonas aeruginosa, Cytomegalovirus), persistent pneumonia, intractable diarrhoea and failure to thrive. There was lymphopaenia affecting both T and B subsets. He developed Graft versus Host disease weeks following transfusion with non irradiated blood. In spite of aggressive microbicidal and supportive therapy including regular immunoglobulin infusions, the child succumbed to infection before a bone marrow transplant could be instituted.
