Bacterial Arthritis

Septic Arthritis

Bacterial arthritis is predominantly caused by Staphylococcus aureus, streptococci, and Neisseria gonorrhoeae. Joint pain and swelling (involving either one or more joints), as well as fever, are three cardinal symptoms seen in these patients. The diagnosis can be made after a proper physical examination, while the determination of the underlying pathogen is achieved through microbiological studies, primarily in the form of blood and synovial fluid cultures.


Presentation

Bacterial arthritis or infection of the joints and the articular tissues is encountered across all age groups. Overall, Staphylococcus aureus is the most common cause (although Neisseria gonorrhoeae is the number one cause of septic arthritis in younger adults), but streptococcal species (including S. pneumoniae, S. viridans, S. pyogenes), tuberculosis, and a range of both gram-positive and gram-negative bacteria can be responsible for the infection [1]. Several conditions have been described in the literature as potential risk factors for bacterial arthritis, including diabetes mellitus, previous skin infection, rheumatoid arthritis (RA), human immunodeficiency virus (HIV) type 1 infection, as well as increasing age, joint surgery, intravenous drug abuse, and the presence of hip or knee prostheses [2] [3]. The clinical presentation is centered around three main complaints - joint pain, swelling, and fever (about 40% of patients have a fever of >39C) [3] [4]. Either one (monoarticular) or more than one (polyarticular) joint can be affected. Gonococcal arthritis is typically polyarticular [5]. The pain is often severe and is exacerbated with minimal movement, thus a decreased range of motion is also an important finding [4] [6]. Additional less common features of bacterial arthritis include erythema of the skin over the infected joint, rigors, excessive sweating, and constitutional symptoms [1] [3] [4] [6].

Workup

The physician's ability to recognize signs and symptoms of bacterial arthritis through a detailed patient history and a thorough physical examination is essential for making the diagnosis. Information regarding the onset and course of symptoms should be noted, whereas the assessment of preexisting comorbidities that could predispose individuals to this infection is mandatory. Joint pain and swelling, as principal complaints, need to be evaluated during a physical exam, and as soon as valid clinical suspicion is raised, a complete laboratory workup must be conducted. Serum inflammatory markers, such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), are often elevated in bacterial arthritis [4]. One of the key steps in solidifying the diagnosis is the analysis of synovial fluid [7]. Many studies have confirmed that the white blood cell count of > 50 × 109/L (with a predominance of polymorphonuclear cells, or PMNs) in synovial fluid is highly indicative of septic arthritis [2] [3] [4]. Furthermore, cultivation of synovial fluid is a definite method for identifying the causative agent of joint infection, and both anaerobic, but more importantly aerobic cultures should be drawn [7]. Gram staining is also described as an important microbiological method in the case of arthritis, but its variable sensitivity is an important limitation [1] [7].

Joint Space Narrowing

  • Later findings include joint space narrowing due to destruction of the joint.Ultrasound is effective at detecting joint effusions.CT and MRI are not required for diagnosis; but if the diagnosis is unclear or the joints are hard to examine (ie.sacroiliac[en.wikipedia.org]

  • Other important diagnostic tests include blood cultures (positive in 50–70% of acute bacterial arthritides) (27), but in only 30% or less of gonococcal arthritis cases) (38), wound cultures (although these often correlate poorly with synovial fluid culture[the-hospitalist.org]

Treatment

  • Abstract The key to successful treatment of acute bacterial arthritis is early diagnosis and initiation of empirical antibacterial therapy. Treatment includes antimicrobial therapy, debridement of the infected joint and treatment of pain.[ncbi.nlm.nih.gov]
  • Thus, we feel that lifelong treatment with antibiotics is a reasonable alternative in cases, where the risk of surgery is very high.[ncbi.nlm.nih.gov]
  • Especially in infants, treatment delay or inappropriate treatment may result in cartilage destruction, avascular necrosis and physeal injury [ 5, 6 ], with an increased risk of severe deformation and functional impairment.[doi.org]
  • A secondary objective was to quantify test and treatment thresholds using derived estimates of sensitivity and specificity, as well as best-evidence diagnostic and treatment risks and anticipated benefits from appropriate therapy.[ncbi.nlm.nih.gov]
  • Abstract Acute bacterial arthritis continues to be a common occurrence, and despite improved treatment regimens, the prognosis has not improved significantly over the past 20 years.[ncbi.nlm.nih.gov]

Prognosis

  • In contrast, gonococcal arthritis is often successfully treated with antimicrobial therapy alone and demonstrates a very low rate of complications and an excellent prognosis for full return of normal joint function.[ncbi.nlm.nih.gov]
  • Abstract Acute bacterial arthritis continues to be a common occurrence, and despite improved treatment regimens, the prognosis has not improved significantly over the past 20 years.[ncbi.nlm.nih.gov]
  • Patients who were older, had a preexisting joint disease, and/or had an infected joint containing synthetic material had the poorest prognosis.[ncbi.nlm.nih.gov]
  • Prognosis: In general, mortality rates are below 5%. Prognosis is poorest in the elderly and those with gram-negative infections, polyarticular involvement, prosthetic joints, or delayed diagnosis.[rheumaknowledgy.com]
