Abstract：Objective To investigate the clinical characteristics of MPP characterized by the feature of lobar pneumoniae. Methods 34 cases of lobar MPP and 60 cases of non lobar MPP hospitalized during January 2011 to December 2013 were retrospectively reviewed. The clinical features, treatments and outcomes were analyzed. Results Compared with the non lobar MPP, the lobar MPP presented high fever, elevated CRP,pulmonary and extrapulmonary complications more frequently(P<0.05), the duration of fever and hospitalization were longer(P<0.05),and patients in this group seemed more frequently to develop into severe MPP(SMPP)(P<0.05).Patients with a CRP level over 40 mg/L more easily developed into SMPP(P<0.05). On the basis of an appropriate antibiotic therapy, patients with lobar MPP needed to combine a low dose of systemic corticosteroid treatment more often to improve the clinical symptoms(P<0.05). Conclusions Compared with the non lobar MPP, patients with lobar MPP often presented a more severe clinical symptoms, a elevated CRP,the incidence of pulmonary and extrapulmonary implications were higher,and the duration of fever and hospitalization were prolonged. Combining with a low dose of systemic corticosteroid treatment could improve the clinical symptoms of lobar MPP , especially for these patients who had poor effect with an appropriate antibiotic therapy.
