Clinical Features of Severe or Fatal Mycoplasma pneumoniae Pneumonia

Abstract Background To observe the effect of corticosteroids in the treatment of children with refractory Mycoplasma pneumoniae pneumonia (RMPP) under different doses, to summarize the clinical features of children treated with glucocorticoid pulse therapy. Methods The clinical data of 125 children with RMPP hospitalized in Tianjin Children’s Hospital from September 2018 to October 2019 were retrospectively analyzed. They were divided into two groups according to the dose of hormone. Compare the clinical features, laboratory findings, and imaging between the two groups, and use meaningful related indicators as ROC curves to find reference indicators for pulse therapy. Results (1) The median age of the group II was older than that of the group I(P < 0.05). (2) We found more severe presentations, higher incidence of extra-pulmonary complications and more serious radiological findings in group II, which needed oxygen more often, higher the hormone, higher usage rate of gamma globulin, higher usage rate of bronchoscopy, and higher incidence of plastic bronchitis(P < 0.05). (3) WBC, CRP, LDH, FER, D-D dimer, APTT, TT, PCT, IL-6 and the percentage of neutrophils in peripheral blood in Group II were higher than those in Group I(P < 0.05). (4) In ROC curve analysis, CRP, LDH, FER, and neutrophils of leukocyte classification were independent related factors that could be used as valuable predictors of methylprednisolone pulse therapy for RMPP in children. The cut-off values were CRP44.45 mg/L, LDH590IU/L, FER411ng/L, and neutrophils in leukocyte classification were 73.75%, respectively. Conclusion CRP ≥ 44.45 mg/L, LDH ≥ 590 IU/L, FER ≥ 411 ng/L, neutrophil≥73.75%, lung consolidation, and pleural effusion may be predictors that guide the treatment of RMPP with pulse dose of GC.

Mycoplasma Pneumoniae Pneumonia

Community-acquired pneumonia (CAP) due to Mycoplasma pneumoniae is usually mild, but some cases develop a severe life-threatening pneumonia. To investigate the clinical features of severe M. pneumoniae pneumonia in adults admitted to an intensive care unit, a multi-centre CAP surveillance study was performed. Among all hospitalized CAP cases between January 2000 and December 2004, there were 227 cases with M. pneumoniae pneumonia without the complication of other pathogens. A total of 13 of the cases required admission to an intensive care unit because of acute respiratory failure (ARF), and the remaining 214 cases (non-ARF) were low to moderately severe. The clinical features of ARF cases were compared with those of non-ARF cases. The underlying conditions in both types of case were identical, whereas clinical findings on admission clearly differed between the two groups. A regimen of an antibiotic effective against M. pneumoniae was begun on average at 9.3 days after the onset of symptoms in ARF cases, which was significantly later than for non-ARF cases (P<0.0001). However, two of the ARF cases progressed to respiratory failure despite the fact that adequate antibiotics were initially administered within 3 days after the onset of symptoms. All ARF cases received corticosteroids with adequate antibiotics, and their condition improved promptly. These results indicate that the clinical features, excluding underlying conditions, clearly differed between severe M. pneumoniae pneumonia and low to moderately severe pneumonia. The delayed administration of adequate antibiotics may contribute to the severity of M. pneumoniae pneumonia. Early corticosteroid therapy with adequate antibiotics should be considered.
