ABSTRACT
From 1988 to 1991 the long-term efficacy of a combined therapy with a polyvalent immunoglobulin/cytomegalovirus (CMV) hyperimmunoglobulin, oral low dose zidovudine, oral cotrimoxazole or inhaled pentamidine was investigated in three groups of human immunodeficiency virus (HIV)-infected children. Group 1A consisted of three perinatally infected children with a CD4 cell decrease of > 400 cells/microliters per year. Group 1B were 17 perinatally infected children with a CD4 cell decrease of < 400 cells/microliters per year. Group 2 comprised eight haemophilic children infected by clotting factors. Despite combined therapy none of group 1A survived longer than 12 months showing a rapid loss of CD4 cell counts, progressive encephalopathy, wasting syndrome and severe bacterial, fungal and CMV reactivation. Under pure intravenous immunoglobulin (IVIG) therapy severe bacterial infections were seen in 1 of 12 children in group 1B. The majority of these patients showed increases or stabilisation of length and weight percentiles. In this group low dose zidovudine therapy was of benefit in HIV-associated neurological symptoms. Nevertheless combined therapy could not prevent further deterioration of CD4 cell counts. In group 2 severe bacterial infections were not seen under IVIG therapy. In this group a temporary increase (6 months) of CD4 cell counts under IVIG/zidovudine combined therapy occurred. Pneumocystis carinii pneumonia (PCP) prophylaxis with oral cotrimoxazole or inhaled pentamidine successfully prevented PCP in all three groups. Under CMV hyperimmunoglobulin (n = 22), ten out of ten patients did not acquire primary CMV infection, whereas CMV reactivations mainly located in the CNS could not be prevented in 5 of 12 patients.(ABSTRACT TRUNCATED AT 250 WORDS)
