Streptococcus pneumoniae causing septic arthritis with shock and revealing multiple myeloma.
The authors present the case of a 43-year-old male who presented at the emergency department, with a mean arterial pressure of 48 mm of Hg, a sinus tachycardia of 142/min and shallow breathing at 30/min. Two days previously, he started a high-grade fever with a concomitant reddish and painful left knee and right elbow, without any treatment. Septic shock was diagnosed and the patient was started on empiric antibiotics combining ceftriaxone and vancomycin and vasopressors (norepinephrine). The painful knee and elbow joints were aspirated and cultures grew Streptococcus pneumoniae. The patient's clinical condition improved progressively and after investigation, the diagnosis of multiple myeloma was concluded. Pneumococcal septic arthritis, an extraordinary cause of septic arthritis, is a manifestation of an underlying disease and can be responsible for septic shock. Its diagnosis should direct further investigations. It can occur in patients with joint disease but should emphasise the search of systemic immunosuppression.
