Septic arthritis caused by Streptococcus suis– A case report

Abstract

Purpose: Human Streptococcus suis infections are zoonotic infections related to swine animals. It is an emergent public health concern in Asia, where it is associated with food-borne transmission and manifestations of meningitis, endocarditis and sepsis in humans. Arthritis is less common.Methods & Materials: We report a case of a 22-year-old portuguese previously healthy man presented to the hospital with fever, myalgias, swelling and pain of the right wrist with two days duration. Laboratory exams revealed leukocytosis (total leucocytes count 15,34x109/L, 70% neutrophil) and a C-reactive protein of 176,2 mg/L. Wrist's ultrasound showed effusion and synovitis of the radio-carpal joint. Arthrotomy was performed for debridement and synovial fluid analysis. Blood cultures were collected. Patient was admitted with the diagnosis of septic arthritis and ceftriaxone was started empirically. Streptococcus suis was isolated on both synovial fluid and blood. According to bacteria susceptibility antibiotherapy was adjusted to penicillin. After 14 days of iv treatment he was discharged home recovered.The patient worked as a butcher who had handled raw pork. He recalled an abrasion injury on his right first finger 2 days before illness onset.Results: In this case, we had unspecific clinical findings but epidemiological context that raised the possibility of a zoonotic disease. The final diagnosis was based on the results of appropriate microbiological tests timely collected. Conclusion:In Europe, as in this case, Streptococcus suis infections are mostly occupational exposures.

Bilateral Sensorineural Hearing Loss and Septic Arthritis in Streptococcus suis Meningitis Patient: A Case Report

“…Patient is discharged after 14 days of antibiotic therapy. [8] Symptoms of joint pain and swelling in patients co-occurring with clinical meningitis S. suis accompanied by the presence of increase in the number of leukocytes on fluid analysis joints can support the diagnosis of septic arthritis Joint fluid cultures in both cases were not shows the development of bacteria even though Synovial fluid analysis results support arthritis septic. This can be explained because both cases have been given antibiotics before joint fluid examination.…”
