[H3N2 subtype of human influenza pneumonia with staphylococcal sepsis and staphylococcal pneumonia: report of one case].

ABSTRACT

To investigate the clinical characteristics, diagnosis and therapy of influenza pneumonia with staphylococcal infection. One patient in our hospital was diagnosed and the literatures on the subject were reviewed. The patient presented with high fever and dyspnea. Arterial gas analysis indicated type 1 respiratory failure. Chest X ray photographs showed bilateral infiltrations and bilateral encapsulated pleural effusions. Viral separation and culture of pharyngeal swab indicated H(3)N(2) subtype of human influenza virus. Blood, sputum and bronchoalveolar lavage fluid (BALF) cultures showed Staphylococcus aureus. Pleural effusion was complex parapneumonic pleural effusion. After the administration of anti-virus, anti-staphylococcal antibiotics and pleural cavity drainage, the patient was cured. The infection of staphylococcus aureus is a typical characteristic of influenza pneumonia, and anti-staphylococcal antibiotic therapy (with MRSA activity in MRSA endemic regions) should be initiated in hospitalized cases of influenza pneumonia. If complex parapneumonic pleural effusion or empyema complicated, we should perform pleural cavity drainage in time. The oral neuraminidase inhibitor (oseltamivir) could significantly improve prognosis.
