OBJECTIVE: To describe the clinical, hematological and radiographic characteristics of children hospitalized for Mycoplasma pneumoniae pneumonia. METHOD: The study population consisted of 190 children between 3 months and 16 years old, hospitalized for radiographically confirmed pneumonia. Patients were divided into two groups, to wit: 95 children with Mycoplasma pneumoniae pneumonia, as diagnosed using the enzyme-linked immunosorbent assay (ELISA) method; and 95 children with pneumonia caused by other etiologic agents. Using a validated scoring system, the clinical, hematological and radiographic findings of both groups were compared to differentiate Mycoplasma pneumoniae pneumonia (group 1) from pneumonia caused by other etiologic agents (group 2), itself divided into two groups, bacterial (n = 75) and viral (n = 20). RESULTS: Mycoplasma pneumoniae pneumonia was found most often in girls (p < 0.01), older children (p < 0.01), and patients with dry cough (p < 0.01) and extrapulmonary manifestations (p < 0.01). The clinical, hematological and radiographic variables of Mycoplasma pneumoniae pneumonia (mean score = 6.95) scored between those found in bacterial (mean score = 8.27) and viral pneumonia (mean score = 0.90). CONCLUSION: Results suggest that the scoring system can contribute to the presumptive diagnosis of Mycoplasma pneumoniae pneumonia and help differentiate pneumonic status caused by other etiologic agents.
