The techniques of serum countercurrent immunoelectrophoresis, hemagglutinating (HA), and bactericidal (BC) antibody determinations were applied to seven patients with Haemophilus influenzae type B cellulitis. Capsular antigen was detected (greater than or equal to 10 ng/ml) in two patients at the time of admission and was found in two additional patients two days following hospitalization. Antibody responses in the patients with cellulitis were deficient, similar to those in children under 2 years of age with H influenzae type B meningitis. One of the patients with cellulitis had HA and BC antibody present in convalescent serum, and two additional patients demonstrated BC activity. The clinical presentations of our patients were typical except that violaceous discoloration of overlying skin was noted in only one of the seven. Two additional patients had atypical facial swelling that closely resembled angioneurotic edema and initially led to incorrect diagnosis. Countercurrent immunoelectrophoresis may be helpful in the diagnosis of patients with Haemophilus cellulitis, particularly if serial serum determinations are performed. Bacterial cultures obtained from blood and aspirates of the lesion appear to be more sensitive in determining the cause of H influenzae type B cellulitis.

Acute infectious cellulitis is a common condition in pediatric patients. We retrospectively studied 28 cases seen over the last four years. Average age of patients was four years. Fever and a decline in general health were often found. Streptococcus pyogenes and Staphylococcus aureus were the most common organisms in our series. Outcome was favorable under early antimicrobial therapy selected according to age and clinical features. Before three months of age, cellulitis suggests a streptococcus B infection and should be treated by ampicillin or parenteral penicillin, combined with an aminoglycoside if called for. Between 4 months and 2 years of age, Haemophilus influenzae b or a pneumococcus are the most likely organisms; Haemophilus cellulitis should be treated by a third generation cephalosporin for ten days or longer, followed by ampicillin or ampicillin-clavulanic acid per os for ten or 15 days. Beyond 2-3 years of age, all organisms may be the cause of cellulitis, but the most likely are Streptococcus pyogenes and Staphylococcus aureus, treatment consists in administration of either a penicillin M or a macrolide, the route being selected according to the general condition and site of the cellulitis.
