The history of a 13-year old boy is reported who suffered from frequent bacterial, enteroviral, and protozoal infections since late infancy. A decrease in the serum levels of IgG2, IgG3, IgA, a neutrophil dysfunction, and a partial cellular immune deficiency could be demonstrated. A deficiency of folic acid produced a pancytopenia which enhanced the patient's susceptibility to infections. The combined substitution of gammaglobulins and folic acid only was able to break this vicious cycle.
