Clinical characteristics of 7 children with Streptococcus pneumoniae cellulitis / 中华实用儿科临床杂志

ABSTRACT

Objective:To explore the clinical characteristics of children with Streptococcus pneumoniae cellulitis. Methods:The bacterial culture information management system in 18 children′s hospitals from January 2012 to December 2017 were reviewed.Among 1 138 children diagnosed with invasive pneumococcal disease(IPD), 7 cases were hospitalized with cellulitis.Clinical information was collected and analyzed.Results:Seven cases of Streptococcus pneumoniae cellulitis accounted for 0.6%(7/1 138 cases) of 1 138 IPD cases in 18 hospitals.There were 5 males and 2 females.The onset age was from 1 month to 6 years old, and the median age was 2 years old.There were 4 cases in rural areas and 3 cases in urban areas.Langerhans cell histiocytosis (LCH) was found in 1 case.Clinical manifestations: fever, local swelling and pain with infection.The focus of cellulitis: orbital cellulitis in 2 cases, buccal infection in 2 cases, upper extremity, head and buttock infection in 1 case, respectively.At the beginning of the disease: 2 cases of orbital cellulitis were accompanied by nasosinusitis and suppurative otitis media, 1 case was treated with acute periapical inflammation, 1 case was 10 months after chemotherapy.Type of infection: 6 cases were complicated with bloodstream infection, 2 cases with bacterial meningitis and 1 case with pneumonia.Other culture results: 6 cases of Streptococcus pneumoniae were cultured in peripheral blood, 2 cases were positive in local pus culture.Drug sensitivity test: 6 cases were sensitive to Penicillin and Cephalosporin (Cefotaxime/Ceftriaxone), 1 case was resistant.Treatment: 3 patients were treated with Cephalosporins alone, 2 cases with Cephalosporins and Penicillins, 2 cases with Vancomycin and Meropenem for meningitis, 3 cases with local abscess by incision and drainage, 2 cases with meningitis in Intensive Care Unit, and 1 case with endotracheal intubation and ventilator assisted ventilation.The average length of stay was 14.3 days(5-41 days). Discharge outcome: 6 cases improved and 1 case died. Conclusions:Cellulitis is a rare type of infection in children with IPD.It is mainly found in the head, face and around the orbit.It may be accompanied by bloodstream infection or bacterial meningitis.Most of them have a good prognosis.
