Abstract:
Objective:To understand the clinical characteristics of empyema caused by Streptococcus pneumoniae in children. Methods:The clinical manifestations, imaging characteristics, treatment and prognosis of 49 children with pneumococcal empyema admitted to Beijing Children′s Hospital, Capital Medical University from March 2007 to February 2018 were retrospectively analyzed.Results:Among the 49 children, 26 were male and 23 were female, with a median age of 2.63 years old.All the cases had cough and fever, 46 cases of them had high fever, 2 cases had moderate fever and 1 case had ultrahyperpyrexia.The course of disease before admission was 2-90 days, with a median of 10 days.All cases had toxic symptoms and signs of pleural effusion; 26 patients had dyspnea; 23 patients had moist rales, while 8 cases of whom had wheezing sounds.Eleven cases had extrapulmonary complications, including purulent meningitis in 6 cases, purulent pericarditis 1 case, 2 cases of hemophagocytic syndrome and hemolytic uremic syndrome respectively.The medians of leukocytes in the whole blood, white blood cells in pleural effusion and multinuclear cell percentage were 26.97×10 9/L, 32×10 9/L and 0.85, respectively.The average C-reactive protein (CRP) was 177.79 mg/L.The drug sensitivity test of Streptococcus pneumoniae showed that 68.89% strains were insensitive to Penicillin and all strains were resistant against Erythromycin.Chest image showed bilateral consolidation in 32 cases and pneumothorax in 31 cases.Besides antimicrobial therapy, 34 patients were treated with chest drainage, and 7 cases underwent surgery.Ten of the 49 cases were treated with nasal continuous positive airway pressure, tracheal intubated was used in 6 cases, and 1 case was given cardiopulmonary resuscitation.Forty-five cases discharged with improvement, 3 cases were not cured and 1 case died. Conclusions:Pneumococcal empyema is more common in children under 5 years old.Children with pneumococcal empyema usually have poor mental status, high fever, cough accompanied by dyspnea, high peripheral white blood cells and CRP.Their radiographic findings are usually serious, and the insensitive rate to Penicillin is high.The main treatment is anti-infection therapy and closed thoracic drainage.The prognosis of most patients is good, but there are still dead cases.
