BackgroundThe aim was to study the course of severe pneumococcal sepsis in patients who rapidly developed septic shock with multiorgan failure.MethodsCombined retrospective and prospective cohort study of all patients with pneumococcal sepsis requiring mechanical ventilation admitted to our Medical Intensive Care Unit at Oslo University Hospital Ullevaal, during an 8-year period (01 January 2006 to 31 December 2013). The inclusion criteria were growth of Streptococcus pneumoniae in blood culture and respiratory failure treated with invasive mechanical ventilation.ResultsThirty-eight patients were included. Median age was 57 years (interquartile range 49-68, range 22-79). For 84% (32/38), it took <24 hours from the first medical evaluation until they were in septic shock. Initial clinical features were variable; none were treated with antibiotics before hospital admission. Median Sequential Organ Failure Assessment (SOFA) score at admission was 11 (range 1-15) and maximum 15 (range 5-22), all patients developed multiorgan failure. Mutilating complications were seen in 47% (18/38) of the patients: six with amputations, 11 had adverse neurological complications and one patient both. In-hospital mortality was 40% (15/38), 20% (8/38) survived with sequelae and 40% (15/38) returned to their habitual state. Poor outcome was associated with meningitis, disseminated intravascular coagulation, and gastrointestinal symptoms.ConclusionIn this patient cohort with pneumococcal sepsis and respiratory failure rapid development of septic shock was seen in all cases, even in young healthy individuals. Initial clinical features were variable; none were treated with antibiotics before admission. Mortality was high (40%), as was morbidity with limb amputations and neurological complications.© 2018 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.
