Terapeutic Remission of Community Acquired Pneumonia Caused by Rothia Mucilaginosa in an Adult Patient with Idiopathic Pulmonar Fibrosis

Abstract

Rothia Mucilaginosa (RM) is part of the microbiota of the pharynx and upper respiratory tract. RM is a gram-positive, enveloped, coagulase-negative coccus of the family Micrococcaceae. Clinical manifestations range from mild bronchitis to recurrent pneumonia and lung abscess. It is difficult to determine the clinical significance of this organism in respiratory specimens, therefore, in the diagnosis of pneumonia caused by R. mucilaginosa, bronchoscopy specimens should be cultured. Risk factors associated with Rothia are hematologic malignancies and neutropenia. At present, the importance of Rothia in various pathologies remains unclear due to its difficulty in culture and high potential for contamination at the time of sampling. Although it is an oral microbiota, it has been implicated in pneumonia after being identified in sputum or bronchoalveolar lavage smears and in infectious lesions of the respiratory tract, such as lung abscess and empyema. The challenge of MRI infection in clinical practice is deciding whether it is a real infection or a product of sample contamination. We present the case of a 50-year-old adult patient, without neutropenia, without hematological malignancy, with progressive idiopathic pulmonary fibrosis (IPF) of 1 year of evolution. On admission to the hospital, this person presented signs of respiratory failure, tachycardia, upper rales. auscultation and 85% oxygen saturation, that's why he went through many different studies to diagnose Rothia Mucilaginosa pneumonia.
