Skin and soft tissue infection caused by Streptococcus pneumoniae: report of 15 cases
Abstract
OBJECTIVE: Streptococcus pneumoniae is a very rare cause of skin and soft tissue infections (SSTI). The aim of this study was to determine the clinical and microbiological characteristics of these infections.
METHODS: The medical records of patients with SSTIs due to S. pneumoniae diagnosed at the University Hospital of Guadalajara between January 2012 and December 2020 were retrospectively reviewed. Microbiological identification was performed using conventional procedures. Antimicrobial sensitivity was performed using the MicroScan WalkAway-96 plus automatic system and E-test strips following the recommendations of the European Committee on Antimicrobial Susceptibility Testing (EUCAST).
RESULTS: Fifteen cases of SSTIs were diagnosed. 73,3% of the cases presented underlying diseases, neoplasias being the most frequent. 60% of the cases presented predisposing factors, immunosuppression being the most common. The clinical presentations were: abscesses in different locations, ulcers, surgical wounds, lactational mastitis and necrotizing fasciitis. Polymicrobial infections were detected in 73.3% and the etiology was nosocomial in 6.6%. The clinical course was favorable in 90.9% of the cases. The antibiotics with the highest percentages of sensitivity against S. pneumoniae were cefotaxime, levofloxacin, vancomycin, linezolid and rifampicin.
CONCLUSIONS: S. pneumoniae should be kept in mind as a possible causative agent of SSTIs, especially in patients with neoplasias and…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
