Abstract
OBJECTIVE: To study the clinical features of children with Mycoplasma pneumoniae pneumonia (MPP) and peripheral lymphocytopenia. METHODS: A total of 310 MPP children who were hospitalized and underwent bronchoalveolar lavage from June 2018 to June 2019 were enrolled and divided into two groups: simple MPP group with 241 children (without peripheral lymphocytopenia) and MPP + peripheral lymphocytopenia group with 69 children. The two groups were compared in terms of clinical data and treatment outcome. RESULTS: Compared with the simple MPP group, the MPP + peripheral lymphocytopenia group had significantly longer duration of fever and length of hospital stay and significant increases in C-reactive protein, lactate dehydrogenase, and Mycoplasma pneumoniae DNA copies in bronchoalveolar lavage fluid (P < 0.05). Compared with the simple MPP group, the MPP + peripheral lymphocytopenia group had significantly higher incidence rates of intrapulmonary consolidation, extrapulmonary complications, and serious lesions under bronchoscopy (erosion or sputum bolt) and a significantly higher proportion of patients with severe MPP (P < 0.05). CONCLUSIONS: Children with MPP and peripheral lymphocytopenia tend to have more severe immunologic injury. Peripheral blood lymphocyte count may be used to evaluate the severity of MPP.
