Systemic infection due to group B beta-hemolytic streptococcus in children. A review of 75 outpatient-evaluated cases during 13 years.

We reviewed 75 outpatient cases of systemic infection due to group B beta-hemolytic streptococcus (GBS) evaluated during a 13-year period. Patient ages ranged from five days to eight months; 75% were younger than two months. Early-onset (less than or equal to seven days of age) GBS disease occurred in 10% of the patients, and late-onset GBS disease in 90%. The racial distribution was 60% black, 35% white, and 5% Hispanic. Symptoms included fever, irritability, lethargy, and altered-feeding pattern which lasted less than 24 hours in 88% of patients. On presentation, 33% were afebrile (eight had GBS meningitis); 32% did not appear ill (six had GBS meningitis). Of the total, 40% had GBS meningitis, of these, a greater proportion had either early-onset GBS disease or neutropenia. Infection other than meningitis was identified in 24% of all patients: pneumonia (six cases), cellulitis/adenitis (six cases), osteomyelitis/septic arthritis (five cases), and otitis media (one case). All patients survived. Systemic GBS infection in an outpatient population can involve infants up to eight months old, is more common in blacks than in whites, can be present without fever or compromised appearance, and usually has low mortality.
