| Abstract
| - The clinical presentation, radiological and laboratory evaluation, treatment, and risk factors of sinusitis in a cohort of 376 human immunodeficiency virus (HIV)-infected children from a placebo-controlled clinical trial of intravenous immunoglobulin (IVIG) as prophylaxis for infections were examined. Ninety-five episodes of sinusitis were described in 60 patients; one-third of the patients had two or more episodes. Sinusitis episodes were commonly associated with nonspecific, chronic symptoms (67.4%, persistent nasal discharge; 54.7%, nocturnal or persistent cough), whereas symptoms more specific to acute sinusitis were less frequent (17.9%, headache or facial pain; 9.5%, periorbital swelling; 25.3%, temperature of ⩽102°F; 9%, total white blood cell count of ⩾15,000/ mm3). The sinuses primarily involved were the maxillary sinus (85.9%) and the ethmoidal sinus (42.3%); 36% of episodes involved two or more sinuses. Preceding respiratory infections did not appear to increase the risk of sinusitis, and CD4+ lymphocyte counts in children with and without sinusitis did not differ. Neither monthly IVIG prophylaxis nor three times weekly trimethoprim-sulfamethoxazole prophylaxis for Pneumocystis carinii pneumonia decreased the risk of sinusitis. Sinusitis in HIV-infected children is most often subacute and recurrent. Evaluations of new modalities for prophylaxis for sinusitis are needed.
