Mycoplasma pneumoniae pneumonia – challenges related to diagnosis and treatment in children

Abstract

Introduction. Pneumonia is a common infectious disease among children, very familiar to pediatricians and a major cause of hospitalization worldwide. Mycoplasma pneumoniae (M. pneumoniae) - atypical pathogen, is estimated to be responsible for approximately 30-40% of community-acquired pneumonias. The aim of the paper was to underline the diagnostic and treatment difficulties in a case of pneumonia with M. pneumoniae in a school-aged boy, with multiple presentations in the Emergency Service for respiratory difficulties. Material and method. We present the case of a 7 years and 10-month-old male patient, admitted to our clinic for wheezing, cough and dyspnea. Results. The clinical exam at admission pointed out influenced general status, wheezing, thoraco-abdominal swing, intercostal draft, sibilant and crackles, oxygen saturation 89%, tachycardia 134 beats/minute. The blood tests revealed mild leukocytosis, with neutrophilia, slightly increased inflammatory biomarkers. Considering the general status and the presence of functional respiratory syndrome, steroid and symptomatic anti-inflammatory treatment is initiated. However, the general condition remains stable, which required the widening of the spectrum of investigations with the performance of a chest CT noticing a pneumonic condensation with an air bronchogram located at the level of the right upper lobe. Considering the stationary respiratory functional syndrome and the radiological appearance of the pneumonia as well as the age, we performed serology for atypical germs and identified a positive titer of Ig M antibodies for M. pneumoniae by instituting Azithromycin po, but after 3 days, the evolution remains stationary, thus we changed the treatment with intravenous Levofloxacin, with a favorable subsequent evolution. Conclusions. Pneumonia with atypical pathogens such as M. pneumoniae is a well-defined and well-known pathology in the literature, but it still remains a condition that imposes multiple difficulties related to the diagnosis and therapeutic management of pediatric cases.
