We conducted an observational study of adults hospitalised with invasive pneumococcal pneumonia to describe the host- and pathogen-related factors associated with respiratory failure. Of 1258 adults with invasive pneumococcal disease, 615 (48.9%) had respiratory failure at presentation. Patients with respiratory failure were older (62.1 years versus 55.4 years, p<0.001) and had a greater proportion of comorbid conditions. They also had a greater proportion of septic shock (41.7% versus 6.1%, p<0.001), required admission to the intensive care unit more often (38.4% versus 4.2%, p<0.001) and had a higher mortality (25.5% versus 3.5%, p<0.001). After adjustment, independent risk factors for respiratory failure were: age >50 years (OR 1.63, 95% CI 1.15–2.3), chronic lung disease (OR 1.54, 95% CI 1.1–2.15), chronic heart disease (OR 1.49, 95% CI 1.01–2.22) and infection caused by serotypes 3 (OR 1.97, 95% CI 1.23–3.16), 19A (OR 2.34, 95% CI 1.14–4.42) and 19F (OR 3.55, 95% CI 1.22–10.28). In conclusion, respiratory failure is a frequent complication of pneumococcal pneumonia and causes high morbidity and mortality. Pneumococcal serotypes 3, 19A and 19F are the main risk factors for this complication. Respiratory failure in invasive pneumonia is determined by older age, comorbidities and serotypes 3, 19A and 19F http://ow.ly/qHN6D ER -
