Poliartritis séptica y fascitis necrotizante en un paciente inmunocompetente. Reporte de caso

Septic polyarthritis in an immunocompetent patient is highly rare, even more when it coexists with necrotizing fasciitis caused by Streptococcus Pyogenes (SP). A 54 year old, immunocompetent male patient is presented herein. The patient had no relevant previous illness, before the installation of a septic arthritis of both knees and he's left ankle. He receives treatment with sequential surgical debridement, then develops necrotizing fasciitis of the posterior aspect of the left leg requiring adequate treatment for such condition (including Vacuum Assisted Closure), as well as antibiotic therapy for the specific infecting microorganism (Penicillin + Vancomycin). Nonetheless, after a month of surgical management between Plastic Surgery, Dermatology, Orthopaedics as well as surveillance in the Intensive Care Unit, the patient dies after multi organic failure. Infection caused by SP might entail high morbidity for a patient and even end with death of the aforementioned caused by a hard to manage systemic organic failure. The adequate diagnosis, as well as aggressive medical and surgical management could not be enough for controlling the infection, even in patients without previous immunological compromise. At the same time, a multidisciplinary approach must be the standard of treatment, aiming to control predisposing infectious conditions. This is the first case reported in national literature related to these two fatal conditions. Finally, one of the purposes of this report is to highlight that despite reports of this microorganism infecting infants and immunocompromised patients, it must not be obviated in healthy patients, especially in cases of rapidly spreading infection and scarce response to adequate management.
