History

  • Symptoms of reactive arthritis generally appear within 1-3 weeks but can range from 4-35 days from onset of inciting episode of urethritis/cervicitis or diarrhea. The classic triad of symptoms, found in only one third of patients with reactive arthritis, has a sensitivity of 50.6% and a specificity of 98.9%.[24]
  • Constitutional symptoms (usually mild):
    • Fever (usually low grade)
    • Malaise
  • Musculoskeletal symptoms:
    • Myalgias (early)
    • Asymmetric arthralgia, joint stiffness, primarily involving the knees, ankles, and feet (wrists may be early target)
    • Low back pain (49%) with radiation to the buttocks or thighs[24]
    • Symptoms worse with rest or inactivity
  • Urethritis associated with reactive arthritis may be postdysenteric or postvenereal, with frequency, dysuria, urgency, and urethral discharge. It may be mild or inapparent. Urogenital symptoms either the result of UG infection or postdysenteric are found in 90% of patients with reactive arthritis.[24]
  • Ophthalmologic symptoms:
    • Erythema
    • Burning
    • Tearing
    • Photophobia
    • Pain
    • Decreased vision (rare)
  • Patients may have mild recurrent abdominal complaints after precipitating episode of diarrhea.

Physical

  • A scoring system for diagnostic points in Reiterlike spondyloarthropathies exists. Two or more of the following points establishes diagnosis (one of which must pertain to the musculoskeletal system):
    • Asymmetric oligoarthritis, predominantly of the lower extremity
    • Sausage-shaped finger (dactylitis), toe or heel pain, or other enthesitis
    • Cervicitis or acute diarrhea within 1 month of the arthritis
    • Conjunctivitis or iritis
    • Genital ulceration or urethritis
  • Musculoskeletal findings:
    • Asymmetric pauciarticular arthritis affecting mainly the lower extremities with low-grade inflammation may be observed.[25]
    • The knee may become markedly edematous.
    • Distinctive arthropathy of reactive arthritis includes local enthesopathy, which is inflammation at the tendinous or ligamentous insertion into bone, rather than synovium (common in insertions into calcaneus, talar, and subtalar joints). Plantar fasciitis is commonly observed.
    • Dactylitis or sausage finger or toe is caused by uniform inflammation and found in approximately 17% of patients.[24]
    • Osteitis
  • Urogenital symptoms may be primary or postdysenteric:
    • Meatal edema and erythema and clear mucoid discharge
    • Prostatitis causing tenderness (up to 80%) and vulvovaginitis
    • Circinate balanitis, shown in the image belowCircinate balanitis in a patient with reactive artCircinate balanitis in a patient with reactive arthritis.
    • Other urogenital symptoms include cervicitis, cystitis, and salpingo-oophoritis.[24]
  • Dermatologic findings:
    • Balanitis circinata - Shallow painless ulcers at meatus and glans penis; moist on uncircumcised patients; may harden and crust on circumcised patients, causing pain and scarring found in 50% of patients[24]
    • Keratoderma blennorrhagica, found in 10% of patients[24] - Hyperkeratotic skin, which begins as clear vesicles on erythematous bases and progresses to macules, papules, and nodules (found on the soles of the feet, toes, palms, scrotum, trunk, and scalp); eventually these coalesce to resemble psoriatic lesions.[26] These plaques and nodules are shown in the images below.

    • Nail dystrophy (thickening and ridging)
    • Superficial oral ulcers (30-60%),[24] shown in the image below Plaques and erosions of the tongue in a patient wiPlaques and erosions of the tongue in a patient with reactive arthritis.
  • Ophthalmologic signs:
    • Conjunctivitis (most common), with mucopurulent discharge, chemosis, lid edema, and iritis
    • Uveitis (12-37%), episcleritis, corneal ulcers, keratitis (4%)[24]
    • Dacryoadenitis has been shown to rarely develop in the setting of chlamydial urethritis.[27]
  • Cardiac signs:
    • Aortic regurgitation caused by inflammation of aortic wall and valve may occur. This proximal aortitis can be found in 1-2% of cases.[26]
    • Transient conduction abnormalities are of little significance, and rarely patients may be affected with myocarditis or pericarditis.[26]

Causes

  • Nongonococcal venereal disease, also known as endemic causes of reactive arthritis (most often due to Chlamydia) and infectious diarrhea, also known as epidemic (Shigella, Salmonella, Yersinia), precipitate reactive arthritis. Bacterial causes endemic or epidemic are mostly the result of gram-negative, obligate, or facultative intracellular pathogens.[20]
  • Data suggest that chlamydial reactive arthritis is underdiagnosed and that asymptomatic chlamydial infections might be a common cause. An important difference between Chlamydia -induced and postenteric reactive arthritis is the presence of viable but aberrant chlamydial organisms in the synovial fluid. This is known as Chlamydia persistence.[28]
  • The most common enteric pathogen resulting in reactive arthritis is Campylobacter (90-95% Cjejuni and 5-10% Ccoli).[17] It has been demonstrated that patients with arthritic symptoms are more frequently infected with C jejuni strains with sialic acid lipo-oligosaccharide. In addition, sialylation of C jejuni lipo-oligosaccharide is also associated with increased severity of enteric disease.[29]
  • Acute tuberculosis infection can sometimes cause reactive arthritis. This is known as Poncet disease, which is a different entity from tuberculous arthritis.[30, 31]
  • In rare cases, C difficile can be associated with reactive arthritis in the pediatric population.[32] Reactive arthritis has also been shown to occur after tetanus vaccination.[33]
  • HLA-B27, an MHC class I molecule involved in T-cell antigen presentation, contributes to the pathogenesis of the disease and reportedly increases the risk of reactive arthritis 50-fold.[26] In addition, HLA-B51 and HLA-DRB1 alleles have also been shown to be associated with reactive arthritis.[34]
  • As mentioned previously, group A Streptococcus can cause poststreptococcal reactive arthritis. These patients demonstrate increase antistreptolysin O (ASO) antibodies and an increased sedimentation rate.[35]
  • Reactive arthritis can also be induced by tonsillitis. In one study, 13 of 21 patients were positive for ASO and 12 were positive for group A Streptococcus.[36]
