Spondyloarthritis (Sp) is newly defined as arthritis that is clinically, pathologically, and genetically related to and predisposed to ankylosing spondylitis (AS) and Reiter's syndrome (RS) rather than to rheumatoid arthritis (RA). A diagnosis of Sp does not necessarily imply arthritis of the spine and does not depend on the demonstration of roentgenographic sacroiliitis that, in this conceptualization, is recognized not as the essential hallmark, but rather merely as a diagnostic "way station" on a continuum of disease, which may (but need not necessarily) begin with RS or be complicated during its course by AS or RS. Spondyloarthritis is distinctively characterized morphologically and clinically by disproportionate inflammation at the entheses, the sites of attachment of tendons and ligaments to bone. Family history or presence of enthesopathic pain, psoriasis, inflammatory bowel disease, uveitis, recurrent urethritis, prostatitis or cervicitis, keratoderma blennorrhagicum, HLA-B27, and asymmetric pauciarticular lower lower extremity arthritis without rheumatoid factor or rheumatoid nodules suggests a diagnosis of Sp rather than RA.

Pi phenotypes were determined in patients hospitalized with ankylosing spondylitis, acute anterior uveitis, psoriasis or chronic prostatitis. The allele frequencies were calculated. No deviation in allele frequencies from Norwegian controls could be demonstrated.

146 men with rheumatoid factor-negative (sero-negative) arthritis, i.e., 97 patients with ankylosing spondylitis, 36 patients with Reiter's syndrome, and 13 patients with reactive arthritis, were examined for infections of the urogenital tract by following recently established criteria. 74 patients (50.7%) had infections of the male adnexes: 3 patients suffered from balanitis, 14 patients from urethritis, 49 patients from prostatitis, 1 patient from epididymitis, and 7 patients from urinary tract infection. Balanitis and urethritis were almost exclusively associated with Reiter's syndrome. In 37 of 97 patients with ankylosing spondylitis, a urogenital tract infection, mainly a prostatitis (31 patients), was detected. The microorganisms isolated most frequently from patients suffering from urethritis and prostatitis, were Chlamydia trachomatis and Ureaplasma urealyticum.

The antiinfectious treatment of rheumatic diseases is certainly very old, but it has gained increased significance as a result of new bacteriological and immunological findings. Urogenital infection as a possible trigger mechanism in reactive arthritides and ankylosing spondylitis was investigated particularly thoroughly. Many experimental, immunological and clinical results indicate a pathogenetic role of infections with chlamydia or mycoplasma in inflammatory rheumatic diseases. However, numerous tests on cultures proved negative, and many serological-immunological findings are inconsistent. The "link" between urogenital infection and rheumatic diseases is still unknown. Of particular interest are the relations between chlamydial prostatitis and ankylosing spondylitis. Earlier findings on the induction of osteogenesis from undifferentiated connective tissue cells by epithelial cells from the prostate could be a basis for further research.

A patient is described who developed signs and symptoms of ankylosing spondylitis after prostatitis due to Trichomonas vaginalis. Chronic prostatitis of unknown cause had previously been reported as being common in patients with ankylosing spondylitis. The observations in this case raise the possibility that T. vaginalis might play a role in the prostatitis and pathogenesis of ankylosing spondylitis in some patients.

Two (7%) out of 29 patients with chronic prostatis were HLA B27 positive. They had roentgenological normal sacro-iliac joints. Two (7%) had sacro-iliitis as judged by radiological examination; one of them had never experienced low back pain. No patient had arthropathy in peripheral joints, ulcerative colitis, Crohn's disease, psoriasis or anterior uveitis. It was concluded that ankylosing spondylitis is rare in patients treated for chronic prostatitis.

We examined 134 male patients with confirmed ankylosing spondylitis. The study protocol included a medical-rheumatological examination and thorough exploration for infections of the urinogential tract. An urethroadnexitis was found in 37 of 134 patients (27.6%): Two patients suffered from balanitis, 17 patients from urethritis, 18 patients from prostatitis, and two patients from epididymitis. Only four patients gave a history of urethritis and eight patients of prostatitis. The microorganisms isolated most frequently from patients with urogenital infection were Chlamydia trachomatis and, in few cases, Ureaplasma urealyticum. By comparing the urethroadnexitis group and the non-infected group with regard to other clinical parameters, we found a significantly increased C-reactive protein in the infected group. Other clinical parameters like involvement of the free spinal column, inflammatory involvement of the joints, and HLA-B27 correlation did not differ significantly.

One hundred and thirty-four male and 32 female patients with ankylosing spondylitis and 33 women with pure ileitis terminalis Crohn were examined. The study protocol included a medical-rheumatological examination and thorough investigation for genitourinary infection. Urethroadnexitis was found in 37/134 male patients (2 patients suffered from balanitis, 17 patients from urethritis, 18 patients from prostatitis, and 2 patients from epididymitis), 15/32 female patients (11 of them had urethritis and in 4 cases urethritis associated with vaginitis) and 5/33 women with ileitis terminalis (every case with urethritis). The microorganism isolated most frequently from patients with genitourinary infection was Chlamydia trachomatis. The majority of patients with genitourinary infection were HLA-B27 positive. Nevertheless, the following conclusions can be reached: (1) evidence of Chlamydia trachomatis infection is frequent in male and female patients with ankylosing spondylitis, (2) patients with genitourinary infection tend to have HLA-B27, and (3) furthermore, presence of genitourinary infection was not significantly associated with chronic illness.

HLA-B27 positive individuals are predisposed to reactive arthritis developing 1-3 weeks after urogenital and gastrointestinal infections. Also ankylosing spondylitis (AS) associates strongly to HLA-B27, but no specific infection, Klebsiella pneumoniae excluded, has been linked to it. Before the discovery of its HLA-B27 association there were many reports suggesting a link between chronic prostatitis in men or pelvic inflammatory disease in women and AS. They have since been forgotten although HLA-B27 did not help to understand, why this disease has an axial and ascending nature. It is proposed that the urogenital organs form a source of damage (or danger)-associated molecular patterns (DAMPs), either exogenous pathogen-associated molecular patterns (PAMPs) from microbes or endogenous alarmins, such as uric acid, released from necrotic cells or urate deposits. DAMPs are slowly seeded from low-down upwards via the pelvic and spinal lymphatic pathways. They reach Toll-like receptors (TLRs) in their target mesenchymal stem cells, which are stimulated to ectopic enchondral bone formation leading to syndesmophytes and bamboo spine. At the same time inflammatory cytokines induce secondary osteoporosis of the spine. This new paradigm places microbes, HLA-B27 and TLRs in the pathogenic centre stage, but without pinpointing any (one) specific pathogen; instead, shared microbial patterns are indicated.
