Abstract
Spondyloarthritis (SpA) is a group of associated chronic systemic inflammatory immune-mediated rheumatic diseases affecting axial and peripheral joints and entheses. The aim of the present study was to identify what parameters are useful to determine in order to better understand the correlation between the disease activity/severity and the microbiological results/immune status against intestinal and/or urogenital pathogens. Microorganisms known to trigger SpA, including Klebsiella spp., Yersinia spp., Salmonella spp., Campylobacter spp. and Chlamydia spp., were analyzed in various specimens (stool, urine, synovial fluid and serum) collected from 27 randomly selected SpA patients and 26 healthy controls using a combined direct and indirect approach relying on conventional culture technique and nucleic acid-based assays together with serological testing by ELISA. Although Escherichia coli derived from phylogroup A prevailed in the gut microflora of the patients and controls, differences were observed regarding the representatives of the other phylogroups with a higher prevalence of E.coli members of phylogenetic group B1 in the stool specimens of patients. Antibodies against the targeted species were detected in SpA patients and controls, and the serological profiles of the former were more diverse and complex. In conclusion, the detection of anti-bacterial antibodies combined with other specific laboratory investigations should be more extensively used to monitor SpA patients in association with their symptoms and in order to determine and administer more effective therapeutics.

Abstract
Spondyloarthritis is a common type of arthritis which affects mostly adults. It consists of idiopathic chronic inflammation of the spine, joints, eyes, skin, gut, and prostate. Inflammation is often asymptomatic, especially in the gut and prostate. The HLA-B*27 allele group, which presents intracellular peptides to CD8+ T cells, is by far the strongest risk factor for spondyloarthritis. The precise mechanisms and antigens remain unknown. In 1959, Catterall and King advanced a novel hypothesis explaining the etiology of spondyloarthritis: an as-yet-unrecognized sexually acquired microbe would be causing all spondyloarthritis types, including acute anterior uveitis. Recent studies suggest an unrecognized sexually acquired fungal infection may be involved in prostate cancer and perhaps multiple sclerosis. This warrants reanalyzing the Catterall-King hypothesis based on the current literature. In the last decade, many links between spondyloarthritis and fungal infections have been found. Antibodies against the fungal cell wall component mannan are elevated in spondyloarthritis. Functional polymorphisms in genes regulating the innate immune response against fungi have been associated with spondyloarthritis (CARD9 and IL23R). Psoriasis and inflammatory bowel disease, two common comorbidities of spondyloarthritis, are both strongly associated with fungi. Evidence reviewed here lends credence to the Catterall-King hypothesis and implicates a common fungal etiology in prostate cancer, benign prostatic hyperplasia, multiple sclerosis, psoriasis, inflammatory bowel disease, and spondyloarthritis. However, the evidence available at this time is insufficient to definitely confirm this hypothesis. Future studies investigating the microbiome in relation to these conditions should screen specimens for fungi in addition to bacteria. Future clinical studies of spondyloarthritis should consider antifungals which are effective in psoriasis and multiple sclerosis, such as dimethyl fumarate and nystatin.

Abstract
Seronegative spondyloarthritis (SpA) are variably associated with HLA-B∗27 antigen. HLA-B∗27 negative SpA has also been reported from different parts of the world. There is paucity of data on this entity from Indian subcontinent. We studied 100 consecutively diagnosed HLA-B27 negative spondyloarthritis patients from a tertiary care center in India. Modified New York Criteria for ankylosing spondylitis (AS) and ESSG criteria for SpA were used for diagnosing patients. HLA-B∗27 typing was done by an in-house PCR-SSP technique in SpA patients to exclude B∗27 positive patients and PCR-SSOP technique was used to type 100 B∗27 negative SpA patients and 100 controls from the same ethnicity. Frequency of B∗07 was significantly increased (B∗07: % PF 54 versus 18; OR 5.348; 95% CI 2.808-10.186; P value 1.14E - 07), whereas frequency of B∗40 was significantly decreased (B∗40: % PF 17 versus 32; OR 0.435; 95% CI 0.222-0.850; P value 0.013) when compared with B∗27 negative controls. Among 100 SpA patients, 47 were undifferentiated spondyloarthritis and 33 patients were reactive arthritis patients. 40% of the patients were suffering from polyarticular arthritis, 35% had pauciarticular arthritis with knee joint, hip joint, ankle joint, and SI joint involvement. We conclude that B∗07 was significantly associated with B27 negative spondyloarthropathy from Western India and majority of B∗27 negative patients were uSpA.

MLST genotypes and antibiotic resistance of Campylobacter spp. isolated from poultry in Grenada. BIOMED RESEARCH INTERNATIONAL 2013; 2013:794643.

Abstract
This study determined whether multilocus sequence types (MLST) of Campylobacter from poultry in 2 farms in Grenada, West Indies, differed by farm, antimicrobial resistance and farm antibiotic use. Farm A used fluoroquinolones in the water and Farm B used tetracyclines. The E-test was used to determine resistance of isolates to seven antibiotics. PCR of the IpxA gene confirmed species and MLST was used to characterize 38 isolates. All isolates were either C. jejuni or C. coli. Farm antibiotic use directly correlated with antimicrobial resistance of Campylobacter isolates. Almost 80% of the isolates from Farm A were fluoroquinolone resistant and 17.9% of the isolates from Farm B were fluoroquinolone resistant. All Campylobacter isolates from Farm A were tetracycline sensitive, whereas 35.7% of isolates from Farm B were tetracycline resistant. Six previously recognized sequence types (STs) and 2 novel STs were identified. Previously recognized STs were those overwhelmingly reported from poultry and humans globally. Isolates with the same ST did not always have the same antibiotic resistance profile. There was little ST overlap between the farms suggesting that within-farm transmission of Campylobacter genotypes may dominate. MLST typing was useful for tracking Campylobacter spp. among poultry units and can help elucidate Campylobacter host-species population structure and its relevance to human health.

Abstract
Reactive arthritis comprises a subgroup within infection-associated arthritides in genetically susceptible hosts. Researchers and clinicians recognize two clinical forms of reactive arthritis which occurs after genitourinary tract infection and after gastrointestinal tract infection. Chlamydia infection has been implicated as the most common agent associated with post-venereal reactive arthritis. Studies have proposed Shigella infection, Salmonella infection, or Yersinia infection as the microorganisms responsible for the post-dysenteric form. The human leukocyte antigen (HLA)-B27 antigen is the best-known predisposing factor. We report a case of HLA-B27-associated reactive arthritis after Salmonella enteritis at Pusan National University hospital.

Abstract
OBJECTIVES Transient synovitis (TS) of the hip is a common cause of limping in children. A link with infection has been suggested but has not been firmly established. We conducted a case-control study to determine whether the TS is associated with infection. METHODS We enrolled children diagnosed with TS in our emergency department over a 10-week period. For each case, we identified an age-matched and sex-matched child with a fracture. Parents of cases and controls were questioned with regard to recent infectious illness in their child according to a predefined questionnaire. RESULTS A paired analysis showed that children with TS (N=29) were more likely to have experienced recent infection with vomiting or diarrhoea (P=0.004) and 'common cold symptoms/runny nose' (P=0.006) than the children with fractures (N=29). Other symptoms suggestive of either viral or bacterial infection were not significantly associated with TS. CONCLUSION TS is associated with symptoms of gastroenteritis and the common cold.

Abstract
A 30-year-old Japanese man developed dactylitis with sausage-like fingers in addition to balanitis and stomatitis. One year prior to these symptoms, acute chlamydial urethritis had been successfully treated by levofloxacin. On admission, Chlamydia trachomatis DNA was not detected in the urine sediment by PCR method, however, he was diagnosed to have reactive arthritis based on the clinical findings of asymmetric dactylitis, circinate balanitis, stomatitis and positivity for HLA B27 antigen. He was treated with methotrexate and his arthritis improved. The past chlamydial infection may have been involved in the pathogenesis of reactive arthritis in this patient.

Abstract
OBJECTIVE To compare the efficacy of a 10-day and a 4-month doxycylcine course for the treatment of Chlamydia trachomatis-reactive arthritis (Ct-ReA). METHODS Patients with active Ct-ReA were enrolled in a prospective, multicentre, double-blind, controlled clinical trial and randomised to receive doxycycline 100 mg twice daily for 10 days followed either by placebo or by continued doxycycline 100 mg twice daily over 4 months. Various clinical and laboratory parameters referring to disease activity were recorded in the beginning and at the end of treatment. RESULTS 32 of 37 patients included (15 men and 17 women; mean (standard deviation) disease duration 17 (13) months completed the study; 17 were randomised to short-term doxycycline and placebo (placebo group) and 15 to prolonged treatment with doxycycline (doxycycline group) over the 4-month study period. After this time, only two patients from each group went into remission. There were no drop-outs owing to adverse events or treatment failures. CONCLUSIONS The results of this study suggest that prolonged treatment with a 4-month course of doxycycline is not superior to short-term treatment over 10 days in patients with Ct-ReA.

Abstract
Nongonococcal urethritis (NGU) is a common sexually transmitted infection most often caused by Chlamydiae and Mycoplasmae. A few other organisms, as well as some nonsexual factors, also contribute to its etiology. NGU can result in considerable physical and psychological morbidity. In a few cases, it can lead to complications like reactive arthritis, and pelvic inflammatory disease, with their attendant morbidities. Correct diagnosis and treatment is therefore imperative in proper management of these cases. While earlier diagnostic support for these infections was limited and expensive, the advent of new methods like the nucleic acid amplification assays (NAA tests) has contributed significantly to better diagnosis. Treatment as per suggested guidelines and follow up of cases and contacts are all crucial in management. Counseling, including advice on behavior change, goes a long way in preventive strategies.

Abstract
What do conjunctivitis, urethritis/cervicitis, and arthritis have in common? These are all clues to the diagnosis of reactive arthritis. It takes a keen eye, a thorough history, a good physical examination, and a broad differential diagnosis to pull together the picture when sorting through seemingly unrelated clinical symptoms. Often a team approach is used when caring for patients with reactive arthritis. This article presents the diagnosis and treatment of reactive arthritis.

Abstract
Development of autoantibodies to intracellular molecules is a universal feature of autoimmune diseases and parallels onset of chronic inflammatory pathology. Initiating antigens of disease-specific autoantibody responses are unknown. We previously showed that the major targets of autoantibodies in scleroderma are centrosomes, organelles involved in mitotic spindle organization. Here we show that centrosome autoantibodies are induced in mice by mycoplasma infection. The centrosome-specific antibody response involves class switching of preexisting IgM to IgG isotypes, suggesting a T cell-dependent mechanism. The antibody response spreads to include additional intracellular targets, with newly recruited autoantibody specificities arising as IgM isotypes. Antibiotic treatment of mice prevents autoantibody development. Centrosome autoantibodies may provide an aetiological link between infection and human autoimmunity and suggest novel therapeutic strategies in these disorders.

Abstract
Mucosal surfaces are important for the induction of immunity against influenza virus. In a murine intranasal immunization model, we demonstrated that the attenuated Shigella flexneri Deltaasd strain 15D, carrying a DNA construct encoding the influenza virus hemagglutinin (HA), induces protective immunity against a lethal respiratory challenge with influenza A/WSN/33. Influenza virus-specific IFN-gamma T cells were detected among splenocytes, and anti-HA IgG was detected in serum post-immunization, albeit at low levels. Following influenza virus challenge, an accelerated anti-HA IgA antibody response was detected in bronchoalveolar lavage (BAL) washings from mice vaccinated with attenuated shigella containing the HA construct. These results suggest that S. flexneri Deltaasd strain 15D is a promising vector for mucosal DNA vaccine immunization against influenza virus and other mucosal pathogens.

PURPOSE The study goal was to investigate the occurrence of serum antibodies to Chlamydia trachomatis, Chlamydia pneumoniae, and Chlamydia psittaci in patients with temporomandibular joint (TMJ) monoarthritis or chronic closed lock and in control subjects. PATIENTS AND METHODS An indirect microimmunofluorescence test for detecting antibodies against C trachomatis was used. Twenty-three patients (12 with monoarthritis and 11 with chronic closed lock) and 42 control subjects were evaluated. RESULTS Six patients with monoarthritis, 5 patients with chronic closed lock of the TMJ, and 6 control individuals were considered to have had a past C trachomatis infection based on their immunoglobulin G titers. Corresponding groups for C pneumoniae investigation included 3 patients with monoarthritis, 4 patients with chronic closed lock, and 17 control subjects, and for C psittaci, 1 patient with monoarthritis, 2 patients with chronic closed lock, and 1 control subject. Statistically significant differences between patients and control subjects were found for C trachomatis only; monoarthritis versus control (P =.016), chronic closed lock versus control (P =.038), and all patients versus control (P =.007). Patients with monoarthritis did not differ from patients with chronic closed lock with regard to antibodies against C trachomatis. CONCLUSION The occurrence of serum antibodies to C trachomatis was significantly higher in patients than in control subjects, but this occurrence did not correlate with severity of observed tissue changes. Nevertheless, an association may exist between the presence of C trachomatis and TMJ disease.

Abstract
INTRODUCTION Arthritis in Reiter's syndrome (RS) is a reactive synovitis associated with a localized infection of the urogenital or gastrointestinal tract with a genetic predisposition. The pathogenetic mechanisms for synovitis in RS are still unknown. Our aim was to examine some of the pathogenetic mechanisms in Reiter's syndrome looking for morphologic changes, immunoprotein deposits and microorganism antigens in synovial biopsies and to determine whether synovial biopsy is useful in diagnosis of RS. MATERIAL AND METHODS Thirty patients with urogenital form of RS were examined within a four-year period. Table 1 illustrates laboratory findings in our patients. We performed synovial biopsies looking for histopathological changes, deposits of immunoproteins and microorganism antigens. Analysis of synovial biopsy specimens was performed using light and immunofluorescence microscopy and fluorescein-labelled monoclonal antibodies to Chlamydia trachomatis. RESULTS Histopathological examination of synovial membrane revealed marked proliferation of the synovial lining cells (SLC) with less or more abundant papillary projections, hypertrophic and edematous tissue with marked vascularisation in 28 (93.3%) cases. Fibrinoid necrosis foci were seen on the surface of synovial tissue. Chronic inflammatory cells (CIC) were diffusely distributed. Edema of the vessel walls, swollen endothelial cells, fibrinoid necrosis in vessel walls as well as multilaminated basement membranes were observed. All histopathologic changes are presented in Table 2. Immunofluorescent techniques in 12 out of 30 (40%) synovial membranes showed immunoglobulin deposits: IgG and IgA deposits were found in vessel walls in 7 cases each and IgM in 10 biopsy specimens. C3 was present perivascularly or within the vessel wall in 4 (13.3%) cases. Sections treated using fluorescein-conjugated antibody revealed Chlamydia in the synovial tissue in 2 patients. CONCLUSION Biopsy specimens with previously described changes in patients with suspected Reiter's syndrome can be useful to confirm the diagnosis. According to our experience, multiple biopsies of abnormal synovia are recommended in these patients.

Abstract
Since 1995, raw vegetable sprouts have been implicated as the vehicle of infection in 15 foodborne outbreaks involving Salmonella and 2 foodborne outbreaks involving Escherichia coli O157:H7. To reduce the numbers of sprout-related outbreaks, the U.S. Food and Drug Administration (FDA) published Guidance for Industry: Reducing Microbial Food Safety Hazards for Sprouting Seeds in 1999. Between October 2000 and April 2001, 61.5% (16 of 26) of the known commercial sprout firms in California were enrolled in a survey to evaluate the industry practices of California sprouting operations and to determine compliance with FDA guidelines. A standardized questionnaire was used to collect data on firm demographics and seed disinfection practices. Additionally, free chlorine levels in seed disinfection solutions were measured, and 48-h spent irrigation water samples were collected from each firm. The irrigation water was screened for Salmonella and E. coli O157:H7 with FDA-recommended test kits. Free chlorine levels in the treatment solutions ranged from 50 to 35,000 mg/liter (ppm), with a median of 14,000 mg/liter (ppm). Free chlorine levels were higher for firms producing alfalfa sprouts than for those producing only mung bean or soybean sprouts (P=0.03). Levels of free chlorine tended to be higher for firms using a calcium hypochlorite treatment solution than for firms using a sodium hypochlorite treatment solution (P=0.067). All 32 irrigation water samples screened for Salmonella tested negative. Of the irrigation water samples tested for E. coil O157:H7, 75% (24 of 32) tested negative, and 25% (8 of 32) tested presumptive positive. The eight presumptive positive samples were found to be negative after further testing. These results indicate that producers of alfalfa sprouts are generally achieving the FDA-recommended calcium hypochlorite level of 20,000 mg/liter (ppm), whereas mung bean sprout producers are not.

Abstract
Reactive arthritis (ReA) is characterized by an aseptic inflammatory articular involvement occurring in a genetically predisposed individual secondary to an infectious process localized outside the joint. ReA usually refers to an acute or insidious oligoarthritis process after enteric (enteroarthritis) or urogenital (uroarthritis) infection. Conventional antirheumatic therapeutic modalities based on nonsteroid anti-inflammatory drugs, sulfasalazine, and steroids are effective in the majority of patients. In more refractory cases, the use of second-line agents including methotrexate and more recently biological agents such as etanercept and infliximab has been found highly effective. The role of antibiotics remains not well established, although they appear to be effective in acute ReA of urogenital origin.

Abstract
Three molecular typing methods were used to study the relationships among 184 Campylobacter strains isolated from humans, cattle, and chickens. All strains were genotyped by amplified fragment length polymorphism (AFLP) analysis, multilocus sequence typing (MLST), and sequence analysis of a genomic region with short tandem repeats designated clustered regularly interspaced short palindromic repeats (CRISPRs). MLST and AFLP analysis yielded more than 100 different profiles and patterns, respectively. These multiple-locus typing methods resulted in similar genetic clustering, indicating that both are useful in disclosing genetic relationships between Campylobacter jejuni isolates. Group separation analysis of the AFLP analysis and MLST data revealed an unexpected association between cattle and human strains, suggesting a common source of infection. Analysis of the polymorphic CRISPR region carrying short repeats allowed about two-thirds of the typeable strains to be distinguished, similar to AFLP analysis and MLST. The three methods proved to be equally powerful in identifying strains from outbreaks of human campylobacteriosis. Analysis of the MLST data showed that intra- and interspecies recombination occurs frequently and that the role of recombination in sequence variation is 50 times greater than that of mutation. Examination of strains cultured from cecum swabs revealed that individual chickens harbored multiple Campylobacter strain types and that some genotypes were found in more than one chicken. We conclude that typing of Campylobacter strains is useful for identification of outbreaks but is probably not useful for source tracing and global epidemiology because of carriage of strains of multiple types and an extremely high diversity of strains in animals.

Abstract
BACKGROUND The aim of this study was to contribute to the insight of the role of the infectious agent in ethiopathogenesis of the Reiter's syndrome development, which could directly influence the choice of treatment of these patients. METHODS Eighteen patients with urogenital form of the Reiter's syndrome and 16 controls (6 with rheumatoid arthritis and 10 with pigmented villonodular synovitis) were included in the study. In all patients standard laboratory analyses of the blood, urine and stool were made; antibody titer to Chlamydia trachomatis and Ureaplasma urealyticum was determined in synovial fluid and serum; isolation of Chlamydia trachomatis and Ureaplasma urealyticum in urethral, cervical and conjunctival swabs, as well as in prostatic and synovial fluid, was also made. HLA typing was done, too. Chlamydia was isolated in the McCoy cell culture treated with cycloheximide, while Ureaplasma was identified according to its biochemical properties grown on cell-free liquid medium. RESULTS Chlamydia trachomatis was isolated from the synovial fluid of 4 patients with Reiter's syndrome (22.2%), while Ureaplasma urealyticum was isolated in 7 of them (38.9%). These microorganisms were not found in any synovial fluid of the control group patients. CONCLUSION Presence of these bacteria in the inflamed joint might be an important factor in etiopathogenesis of this disease, and it supports the hypothesis that arthritis in Reiter's syndrome is probably of the infectious origin.

Abstract
PURPOSE To study HLA-B27(+) and HLA-B27(-) patients with AAU with respect to the frequency and specificity of organ-specific and non-organ-specific autoantibodies. METHODS Fifty-seven consecutive patients with AAU were subjected to ophthalmologic and rheumatologic evaluation as well as to autoantibody determination: antinuclear antibodies (ANA), rheumatoid factor (RF), anticardiolipin, anti-smooth muscle, and anti-parietal cell antibodies, and immunoblot for antibodies to HeLa cells and to bovine iris extract. HLA-B27 was determined by a microlymphocytotoxicity assay. Statistical analysis employed chi-square test, Fisher's exact test, and McNemar test. RESULTS Thirty-four patients had the HLA-B27 allele (B27(+)/AAU) and 23 did not (B27(-)/AAU). ANA, RF, anticardiolipin, and anti-parietal cell antibodies appeared in low frequency. No patient presented anti-smooth muscle antibody. Immunoblot showed a high frequency of antibodies to HeLa cell proteins in B27(-)/AAU patients with predominant reactivity at 46 kDa and 56 kDa. In contrast, sera from B27(+)/AAU patients reacted poorly against HeLa cell antigens. Immunoblot with bovine iris extract showed a significant frequency of antibodies in both groups, with a predominant response to antigens with an estimated mobility of 35, 52, and 54 kDa. CONCLUSION Antibodies specific to iris antigens were equally frequent in both acute uveitis groups, whereas non-organ-specific autoantibodies, especially those to HeLa cell proteins, were far less frequent in B27(+)/AAU than in B27(-)/AAU patients.

Abstract
Reactive arthritis (ReA) is definitely caused by an infection. Several observations suggest that the triggering microbe may persist in the tissues of the patient for a prolonged time. The obvious conclusion is to consider antibacterial treatment. In two instances antibacterial agents are of definite value: in the primary and secondary prevention of rheumatic fever and for early eradication of Borrelia burgdorferi in order to prevent development of the arthritis associated with Lyme disease. Altogether, clinical and experimental data exist to indicate that if antibacterial treatment of ReA can be started very early during the pathogenetic process, the disease can be prevented or the prognosis improved. In fully developed ReA, the value of antibacterial agents is less certain. All available evidence indicates that short term antibacterial treatment has no effect on the prognosis and final outcome of ReA, and the results with long term administration of antibacterials are also overall poor. In some instances sulfasalazine appears useful, rather as a result of its antirheumatic effect or influence on an underlying inflammatory bowel disease than its action as an antibacterial agent. Tetracyclines have also been found to have an effect on ReA, but again, this is probably due to their anti-inflammatory action rather than any antibacterial effect.

Abstract
Reactive arthritis is one of the spondyloarthropathy family of clinical syndromes. The clinical features are those shared by other members of the spondyloarthritis family, though it is distinguished by a clear relationship with a precipitating infection. Susceptibility to reactive arthritis is closely linked with the class 1 HLA allele B27; it is likely that all sub-types pre-dispose to this condition. The link between HLA B27 and infection is mirrored by the development of arthritis in HLA B27-transgenic rats. In this model, arthritis does not develop in animals maintained in a germ-free environment. Infections of the gastrointestinal, genitourinary and respiratory tract appear to provoke reactive arthritis and a wide range of pathogens has now been implicated. Although mechanistic parallels may exist, reactive arthritis is distinguished from Lyme disease, rheumatic fever and Whipple's disease by virtue of the distinct clinical features and the link with HLA B27. As in these conditions both antigens and DNA of several micro-organisms have been detected in joint material from patients with reactive arthritis. The role of such disseminated microbial elements in the provocation or maintenance of arthritis remains unclear. HLA B27-restricted T-cell responses to microbial antigens have been demonstrated and these may be important in disease pathogenesis. The importance of dissemination of bacteria from sites of mucosal infection and their deposition in joints has yet to be fully understood. The role of antibiotic therapy in the treatment of reactive arthritis is being explored; in some circumstances, both the anti-inflammatory and anti-microbial effects of certain antibiotics appear to be valuable. The term reactive arthritis should be seen as a transitory one, reflecting a concept which may itself be on the verge of replacement, as our understanding of the condition develops. Nevertheless it appropriately describes arthritis that is associated with demonstrable infection at a distant site without traditional evidence of sepsis at the affected joint(s). Although several forms of disease could be described as "reactive", particularly acute rheumatic fever, post-meningococcal septicaemia arthritis and Lyme disease, in clinical practice the term is restricted to an acute spondyloarthritis, usually, but not exclusively, linked to acute genitourinary or gastrointestinal infection. A proportion of patients fulfil criteria for Reiter's Syndrome [1].

Abstract
It is well known that arthritis can be associated with venereal disease. Nowadays septic arthritis and reactive arthritis (usually classified as Reiter's syndrome) are distinguished. To place current knowledge within its historical context we reviewed the medical literature on sexually acquired arthritis in the nineteenth century and examined the medical records of London teaching hospitals from this period. We used original sources of rheumatological literature at major London libraries, including the Heberden library of the Royal College of Physicians, and visited the archives at three London teaching hospitals to review original case records and examine diagnostic registers. The first clear description of arthritis associated with venereal disease was given by Swediaur (1798/1809) in French. It became relatively common in London from 1820 onwards with 13 cases described in the literature between 1818 and 1836. It accounts for 3% of admissions at University College and St Bartholomew's Hospitals between 1835 and 1839 and also 3% of admissions at the London Hospital from 1895 to 1900. In the 50 years after Swediaur's report, arthritis associated with venereal disease seemed quite common. This may have been related to the industrial revolution or other social diseases. Historical observations suggest its evidence may vary considerably with time.

Abstract
BACKGROUND Chlamydia trachomatis is associated with Reiter's syndrome and reactive arthritis but the form in which the organism survives in synovial cells is unclear. AIM To compare in situ hybridisation with direct fluorescence in the detection of inapparent chlamydial infection in synovial tissue. METHODS Synovial tissue from four patients with reactive arthritis patients was examined using biotin labelled probes for chlamydial DNA and fluorescein isothiocyanate (FITC) labelled monoclonal antibodies against the major outer membrane protein. RESULTS In two of the four patients, evidence of chlamydial infections was detected by in situ hybridisation in parallel sections but not with FITC labelled monoclonal antibodies. CONCLUSIONS Detection of chlamydial DNA by in situ DNA hybridisation may be a better way to identify chlamydial infection in synovial tissue than phenotype targeting with FITC conjugated antibodies, which is used as a standard procedure for screening clinical specimens for chlamydia.

Abstract
One of the most significant extraintestinal manifestations of gastrointestinal diseases is rheumatologic disorders. The gastrointestinal diseases with rheumatologic manifestations can be divided into two major categories: intestinal disorders and disorders of the liver, biliary tree, and pancreas. The cause of diseases in each of these categories is different. Although intestinal permeability and immune responsiveness are frequently implicated in disorders of the intestine, diseases of the liver, biliary tree, and pancreas usually involve the production of autoantibodies, cytokines, or enzymes. Treatment of rheumatologic complications frequently involves therapy directed at the underlying gastrointestinal disease.

Abstract
Concepts about reactive arthritis are changing and must embrace consideration of the fact that bacteria or their products are present in the joint, not just at the portal of entry in the gastrointestinal (GI) or genitourinary (GU) tracts. With chlamydia-associated disease, atypical elementary bodies can be seen in synovium by electron microscopy, and nucleic acids, including RNA, can be found. It is not yet clear if bacterial nucleic acids are present in postenteric reactive arthritis and whether disease courses are predictably different after GI or GU infection. How bacteria are disseminated to joints and local factors, including cytokines that influence their persistence, are under study. Treatment with antibiotics may help some chlamydia-associated reactive arthritis but is not invariably effective.

Abstract
OBJECTIVE Bacteria are considered to be important in the pathogenesis of several forms of arthritis. The goal of this study was to apply the 16S ribosomal RNA (rRNA)-polymerase chain reaction method for the detection of bacterial DNA in synovial fluid (SF) and synovial tissue (ST) from inflamed joints. METHODS Samples from 5 patients with septic arthritis and from 7 with osteoarthritis or arthritis secondary to joint trauma were used as controls. Samples from 6 patients with spondylarthropathy (SpA) and from 20 with undifferentiated arthritis (UA) were analyzed for the presence of bacterial DNA using universal 16S rRNA primers. Automated sequencing and comparative data analysis were performed to identify the species. RESULTS In the positive control group, the bacterial species cultured from the synovium could be identified in all cases. No bacterial DNA was detected in the SF and ST from patients in the negative control group. In 4 of 6 patients with SpA and 7 of 20 with UA, the analysis of joint samples revealed the presence of bacterial DNA. Sequence analysis indicated the presence of multiple species, which was confirmed by sequencing of cloned products. CONCLUSION When the the above techniques were used with a stringent regimen, we were able to demonstrate that it is possible to collect and analyze joint samples without contaminating bacterial DNA. The accumulation of phagocytic cells that contain bacterial DNA of various species could play a role in the pathogenesis of both SpA and UA.

Abstract
Sera from patients with sexually acquired reactive arthritis (SARA) with antibodies reacting with C. trachomatis and C. pneumoniae (group 1; n = 20) and also with C. psittaci (group 2; n = 19) were analyzed for antibody specificity. Sera from group 2 reacted significantly more often with C. trachomatis serotype E, H and K and had higher antibody titers to serotype E, as tested by microimmunofluorescence tests. Cross-reactivities occurring in microimmunofluorescence tests were related to the presence of antichlamydial lipopolysaccharide antibodies, adsorption of which by recombinant lipopolysaccharide removed microimmunofluorescence reactivity with C. psittaci antigen. In group 2, significantly more sera had antibodies to C. pneumoniae, remaining after lipopolysaccharide adsorption, as proved by adsorption with viable C. trachomatis and C. pneumoniae organisms. None of the sera had antibodies to Yersinia enterocolitica, Shigella flexneri, Sh. sonnei and Salmonella spp. It was observed that the frequency and titer of cross-reacting antibodies to chlamydial serotypes and species were related to the time period between the diagnosis of genital chlamydial infection and of SARA. Cross-reactivities were also related to the presence of lipopolysaccharide, but not heat shock protein 60- or neutralizing antibodies to chlamydiae. Antibody reactivity induced by antichlamydial lipopolysaccharide antibodies can be removed by lipopolysaccharide adsorption.

Abstract
OBJECTIVE Analysis of the interaction of enteropathogenic bacteria with HLA B27 transfected murine fibroblasts showed a specific influence of HLA B27 on microbial invasiveness. This possible novel mechanism for the action of HLA B27 should be verified by using endogenous HLA B27 positive and negative human fibroblasts as a model for the direct interaction of arthritogenic bacteria and host cells. METHODS Fibroblasts were obtained from healthy donors positive or negative for HLA B27; cultivated as monolayers; and infected with Salmonella enterica serovar enteritidis. RESULTS Invasion and survival of bacteria in human cells was not influenced by the presence of HLA B27. Enhancement of HLA class I molecule expression by treatment of cultures with interferon gamma decreased invasion and survival of bacteria in both HLA B27 positive and negative cells. After disappearance of live bacteria lipopolysaccharide antigens persisted within cells. CONCLUSION Endogenous HLA B27 does not modulate the direct interaction of Salmonella with human cells. Non-professional phagocytes are able to limit bacterial survival in cells, and interferon gamma accelerates killing of bacteria, but arthritogenic antigens persist after disappearance of live bacteria.

Abstract
An abundant body of literature suggests that the cellular immune system plays a key role in the autoimmune destruction of insulin-secreting pancreatic beta cells that results in insulin-dependent diabetes mellitus (IDDM). For years, studies have supported the concept that molecular mimicry, a process of antigenic crossreactivity resulting from similarity in amino acid sequence or structure, could be one pathway whereby this disease is induced or its natural history modulated. However, the transfer of this 'hypothesis' to that of a proven mechanism underlying this clinical disorder has been slow and never fully achieved. This article reviews the theoretical basis for molecular mimicry in autoimmune disease and the evidence supporting its role in the pathogenesis of IDDM.

Abstract
A variety of systemic diseases may affect both the hand and eye, leading to profound sensory and functional deficits. The aetiology of some of the most common conditions is reviewed, with an explanation of their manifestations in the hand and eye. Recognition of the association between a hand condition and ocular pathology may aid in diagnosis of a systemic disorder or allow early detection and prevention of ocular disease and loss of vision.

Abstract
Insulin-dependent diabetes mellitus (IDDM) in humans and the non-obese diabetic mouse is a polygenic disease, resulting from an autoimmune destruction of the insulin-secreting pancreatic beta cells. At least in NOD mice, the process is mediated through a T helper 1-cell-mediated cytotoxicity pathway. Although there is much circumstantial evidence to suggest that IDDM is environmentally induced, recent studies support the possibility that the inductive event involves cross-reactive immune responses to antigenic epitopes acting as molecular mimics between microbial proteins and autoantigens expressed by pancreatic insulin-secreting beta cells. The following article reviews the evidence for this concept.

Abstract
HLA-B27 is present throughout Eurasia but is virtually absent among the genetically unmixed native populations of South America, Australia, and among equatorial and southern African Bantus and Sans (Bushmen). It has a very high prevalence among the native peoples of the circumpolar arctic and subarctic regions of Eurasia and North America, and in some regions of Melanesia. Results of recent epidemiologic studies of spondyloarthropathies in populations with a relatively high prevalence of B27 are also reviewed.
