OBJECTIVE: The aim of this study was to compare clinical, microbiological, enzymatic, and host immune response variables between subjects hospitalized with facial cellulitis, with Ludwig's angina (LA) and without Ludwig's angina (WOLA). STUDY DESIGN: Microbiological and enzymatic tests on pus, and hematological and immunological assessments on blood samples of 15 patients with LA and 42 patients with WOLA were performed. Laboratory findings of both groups were compared using the Student t test. Multiple logistic regression analysis was performed and significant differences identified by univariate analysis. RESULTS: Patients with LA demonstrated increased levels of white blood cell counts, urea, and CRP levels, and decreased levels of CIC compared with patients WOLA. However, only CRP and urea were found to be significantly raised in the LA group. A greater population of Staphylococcus aureus and black-pigmented bacteroides were isolated from patients with LA. CONCLUSION: Elevated levels of CRP and urea could indicate the severity of infection in patients with LA. This could be because of the highly virulent and fast-spreading organisms, S. aureus and black-pigmented bacteroides, which may be a factor indicative of LA.
