The suspicion of septic arthritis and infectious tenosynovitis substantially increased on day 6 with worsening symptoms, involvement of additional joints, and spiking fevers. Group G Streptococcus was obtained from the aspirate of the left wrist and from the surgical specimens from the bilateral wrists. The clinical presentation, MRI imaging studies, and surgical and nonsurgical specimens supported a diagnosis of GGS tenosynovitis. However, there was no clear evidence (ie, positive culture with identified organism) of septic arthritis, likely secondary to early septic arthritis and initiation of antibiotics before joint aspirations. The aspirate from the left ankle was yellow and opaque, but the culture was negative.
The pathogenic organism in the patient was GGS. Group G Streptococcus is normal flora of the oral cavity, gastrointestinal (GI) tract, upper respiratory tract, genital tract, and skin, which were all possible sources of seeding.18 Streptococcal species account for about 20% of septic arthritis, and GGS arthritis accounts for 4% to 19% of streptococcal arthritis.19-22 From a review of the literature, 2 cases of GGS tenosynovitis have been published.23,24 However, in an ultrasound study and MRI study, 49% and 43%, respectively, of patients with RA had tenosynovitis of the tendons of the hands.15,25
About three-quarters (71%) of patients with GGS arthritis are male.19 The analysis of the literature by Bronze and colleagues found that chronic joint disease and alcoholism are present in 34% and 14% of patients with GGS arthritis, respectively. One-quarter (23% from Dubost and colleagues) to one-third (32% from Schattner and colleagues) of patients with GGS arthritis have RA.19,26
Fever is present in less than half (43%) of patients with GGS arthritis.19 Positive synovial fluid is expected in 90% of patients.19 Leukocytosis and elevated ESR need not be present.27,28 The arthritis is polyarticular in one-quarter of patients (24% from Bronze and colleagues and 26% from Dubost and colleagues).19,26
Positive blood cultures can be expected in one-fourth (26%) of patients with GGS arthritis.19 The patient’s blood cultures were negative. Blood cultures drawn before initiation of antibiotics yielded no growth, so if the spread was hematogenous, the bacteremia was transient or intermittent. Before and after initiation of antibiotics, specimens from the shoulders did not grow colonies, whereas specimens from the wrists did. If the shoulders were truly infected, these findings and the notably later involvement of the shoulders suggest that the shoulders may have been seeded later in the hospital course.
Trenkner and colleagues proposed that GI abnormalities provide a portal of entry for GGS, which is under the umbrella of S. milleri.29S. milleri is associated with abscess formation, usually of the GI tract.30-32 In the study patient, the possible gastroenteritis may have provided such a portal of entry and subsequent seeding to the joints, and an abscess was found in the left wrist.
Additionally, bilateral EPL tendon rupture likely occurred as a consequence of the inflammatory process from RA and infectious tenosynovitis in the patient. According to Zheng and colleagues, tenosynovitis is an inflammatory process of the synovial tendon sheath that may result in degeneration and rupture of the tendons and may contribute to bone erosions, development of joint deformities, and loss of functional capacity.33 In a histologic study of a ruptured EPL tendon from a patient with RA, Harris observed a chronic inflammatory cellular reaction.34 Harris also described a male with RA with unconfirmed bilateral EPL rupture.34 Björkman and colleague identified previous injury, RA, and local or systemic steroids as important etiologic factors for EPL tendon rupture.35
As in the case of this patient, the utilization of both medical and surgical therapy is not uncommon for treating GGS infection. Antibiotic therapy typically consists of penicillin (74%).26 Surgical intervention is necessary in 16% to 37% of patients.19,26 This patient required both penicillin and incision and drainage/debridement before significant clinical improvement was noted. Prognosis of GGS arthritis is favorable with 5% mortality.26
Septic arthritis and infectious tenosynovitis are readily treatable with low mortality if promptly identified. Identification can be masked by other medical conditions, such as RA and psoriasis, and their associated immunosuppressive treatment. Bilateral EPL tendon rupture may be a complication of RA, particularly with an underlying septic arthritis and infectious tenosynovitis.
