Abstract
Probiotics have been used to ameliorate gastrointestinal symptoms since ancient times. Over the past 40 years, probiotics have been shown to impact the immune system, both in vivo and in vitro. This interaction is linked to gut microbes, their polysaccharide antigens, and key metabolites produced by these bacteria. At least four metabolic pathways have been implicated in mechanistic studies of probiotics, based on mechanistic studies in animal models. Microbial⁻immune system crosstalk has been linked to: short-chain fatty acid production and signaling, tryptophan metabolism and the activation of aryl hydrocarbon receptors, nucleoside signaling in the gut, and activation of the intestinal histamine-2 receptor. Several randomized controlled trials have now shown that microbial modification by probiotics may improve gastrointestinal symptoms and multiorgan inflammation in rheumatoid arthritis, ulcerative colitis, and multiple sclerosis. Future work will need to carefully assess safety issues, selection of optimal strains and combinations, and attempts to prolong the duration of colonization of beneficial microbes.

Abstract
INTRODUCTION Patients with autoimmune rheumatic diseases are more susceptible to infection, owing to the underlying disease itself or to its treatment. Most commonly, infections affect the respiratory and urinary tracts. One of the etiological factors of infections in these patients is the bacteria of the genus Legionella. OBJECTIVES The aim of the study was to assess the prevalence of anti-Legionella pneumophila (L. pneumophila) antibodies in patients with autoimmune rheumatic diseases and to analyze individual and environmental risk factors for the development of Legionella infection in patients with positive antibody results. PATIENTS AND METHODS The study group consisted of 165 patients with autoimmune rheumatic diseases and 100 healthy subjects. Serum samples were tested for the presence of specific antibodies in the immunoglobulin (Ig) M and IgG classes against L. pneumophila serogroups 1 to 7 (SG 1-7) and the IgG class for serogroup 1 (SG 1). RESULTS Antibodies against L. pneumophila were found in 7 patients (4%): 5 cases with antibody positivity only in the IgG class and 2 cases with antibody positivity in both classes. In patients with positive IgG antibodies for SG 1-7, specific antibodies for L. pneumophila SG 1 were not detected. In the control group, positive results were obtained in 9 cases (9%): IgM positivity in 6 (6%) and IgG positivity in 3 (3%). CONCLUSIONS The frequency of antibodies to L. pneumophila in our patients is comparable to that in healthy individuals. L. pneumophila should be recognized as a potential pathogen in patients with autoimmune rheumatic diseases. Primary disease condition, immunosuppressive therapy, and other risk factors should not be ignored in these patients.

Abstract
The study was carried out concerning capability of 194 strains of opportunistic microorganisms to form bio-films. It is established that bacteria ecizing organism of patients with rheumatic diseases have capacity to form microbial bio-films. The formation of bio-films is manifested with the same rate as in agents of inflammatory processes. At that, Escherichia coli, Staphylococcus haemolyticus and bacteria of genus Proteus isolated under rheumatic diseases have significantly higher capability to form biofilms that matters for development of comorbide infections.

Abstract
The relationship between infection and autoimmunity has been increasingly defined over the last 20 years. The systemic rheumatic diseases are characterized by dysregulation of the immune system resulting in a loss of tolerance to self-antigen. The exact etiology for the majority of these diseases is unknown; however, a complex combination of host and environmental factors are believed to play a pivotal role. Helicobacter pylori (H. pylori) is one of the most widely studied infectious agents proposed as agents triggering autoimmune response. The persistent presence of H. pylori in the gastric mucosa results in chronic immune system activation with ongoing cytokine signaling, infiltration of gastric mucosa by neutrophils, macrophages, lymphocytes, as well as production of antibodies and effector T-cells. Various mechanisms have been proposed in an attempt to explain the extra-intestinal manifestations of H. pylori infections. These include: molecular mimicry, endothelial cell damage, superantigens and microchimerism. I performed a systematic literature review using the keywords “rheumatoid arthritis”, “Sjögren’s syndrome”, “systemic sclerosis”, “systemic lupus erythematosus”, “Helicobacter pylori” and “pathogenesis”. A systematic literature search was carried out in MEDLINE; EMBASE; Cochrane Library and ACR/EULAR meeting abstracts. In systemic rheumatic diseases H. pylori infection prevalence alone should not be expected to provide sufficient evidence for or against a pathologic role in the disease. In this article I review studies examining the potential involvement of H. pylori infection in autoimmune systemic rheumatic diseases. Further studies of the immunological response to H. pylori and its role in the pathogenesis of systemic rheumatic diseases are warranted.

Abstract
The infections very often complicate the course of autoimmune rheumatic diseases. In diagnostic of septic complications in rheumatic patients the new biomarkers of infections can have a decisive importance. The procalciotonine test is one of them. The issue was to evaluate the diagnostic informativity of this test. The sample included 93 patients. The examination was applied to 65 patients with rheumatic diseases. Among them, 13 patients had bacterial infections. The group consisted of 33 patients with rheumatoid arthritis, 11 patients with systemic lupus erythematous, 6 patients with systemic angiitis, and 15 patients with other rheumatic diseases. The comparative group included 27 patients of cardio-therapeutic profile and 8 of these patients had bacterial infections. The procalcitonine test was applied with quantitative electrochemiluminescent technique. In patients with rheumatoid arthritis the mean levels of procalciotonine test consisted 0.10 +/- 0.13 ng/ml; with systemic lupus erythematous--0.08 +/- 0.06 ng/ml; with systemic angiitis--0.22 +/- 0.2 ng/ml; with other rheumatic diseases--0.12 +/- 0.15 ng/ml; of cardio-therapeutic profile without infections--0.08 +/- 0.06 ng/vl/ With threshold of procalcitonine test higher than 0.5/ml the sensitivity to diagnostic of infections consisted of 58%, specificity--94% in the group with rheumatic diseases. The procalciotonine test in case of no infection process with values higher than 0.5 ng/ml was detected in three patients. The evaluation of dependence of sensitivity and specificity for procalciotonine test and C-reactive protein the area under curve of procalcitonine test was larger in patients with rheumatic diseases (0.85 against 0.79) and in patients of cardio-therapeutic profile (0.92 against 0.90). The quantitative procalcitonine test is the best technique to detect septic complications in rheumatic patients.

Abstract
Syphilis is a disease caused by Treponema pallidum infection with protean clinical manifestations. Musculoskeletal complaints are however uncommon and most of the time mild. Occasionally they can dominate the clinical picture and simulate a variety of rheumatic diseases. The authors present the clinical case of a 33-year-old woman who developed a lupus-like syndrome in the postpartum, characterized by polyarthritis, elevated acute phase reactants and positive antinuclear antibodies (ANA). Physical examination revealed a macular non-pruriginous skin rash involving the trunk, upper limbs and palms. The Rapid Plasma Reagin (RPR) and Treponema Pallidum Hemaglutination (TPHA) tests gave a positive result and the patient was diagnosed as secondary syphilis and medicated with 2.4 MU of benzathine penicillin intramuscular weekly for 3 weeks, with complete resolution of clinical signs and ANA negativation. The association of rash and arthritis may occur in several rheumatic diseases but in the presence of palmoplantar involvement, the possibility of syphilis infection should not be overlooked.

Abstract
Protracted rheumatological manifestations especially arthralgia and or polyarthritis may occur as a consequence of a wide range of pathogens including viral, bacterial and parasites. Few pathogenetic mechanisms leading to these clinical presentations have been suggested including a direct invasion of the synovial cells by the pathogens, immune complex formation, and others. The natural history of infectious arthritis/arthralgia is altogether benign, with full recovery and without sequelae, albeit sometimes very long. Diagnosis of infections-related arthralgia/arthritis is important since these diseases have a better prognosis, and can relieve anxiety among patients who are afraid of developing a chronic rheumatic disease. Since many patients will seek medical advice with these chronic complaints a long time after travel, physicians should be aware of the possible association between these complaints and remote travel. Thus, travel history should be mandatory, even in a rheumatologic setting.

Abstract
OBJECTIVE To analyse the performance of a new M. tuberculosis-specific interferon gamma (IFNgamma) assay in patients with chronic inflammatory diseases who receive immunosuppressive drugs, including tumour necrosis factor alpha (TNFalpha) inhibitors. METHODS Cellular immune responses to the M. tuberculosis-specific antigens ESAT-6, CFP-10, TB7.7 were prospectively studied in 142 consecutive patients treated for inflammatory rheumatic conditions. Results were compared with tuberculin skin tests (TSTs). Association of both tests with risk factors for latent M. tuberculosis infection (LTBI) and BCG vaccination were determined and the influence of TNFalpha inhibitors, corticosteroids, and disease modifying antirheumatic drugs (DMARDs) on antigen-specific and mitogen-induced IFNgamma secretion was analysed. RESULTS 126/142 (89%) patients received immunosuppressive therapy. The IFNgamma assay was more closely associated with the presence of risk factors (odds ratio (OR) = 23.8 (95% CI 5.14 to 110) vs OR = 2.77 (1.22 to 6.27), respectively; p = 0.009), but less associated with BCG vaccination than the TST (OR = 0.47 (95% CI 0.15 to 1.47) vs OR = 2.44 (0.74 to (8.01), respectively; p = 0.025). Agreement between the IFNgamma assay and TST results was low (kappa = 0.17; 95% CI 0.02 to 0.32). The odds for a positive IFNgamma assay strongly increased with increasing prognostic relevance of LTBI risk factors. Neither corticosteroids nor conventional DMARDs significantly affected IFNgamma responses, but the odds for a positive IFNgamma assay were decreased in patients treated with TNFalpha inhibitors (OR = 0.21 (95% CI 0.07 to 0.63), respectively; p = 0.006). CONCLUSIONS These results demonstrate that the performance of the M. tuberculosis antigen-specific IFNgamma ELISA is better than the classic TST for detection of LTBI in patients receiving immunosuppressive therapy for treatment of systemic autoimmune disorders.

Abstract
It is thought that in genetically predisposed individuals, autoimmune diseases can be promoted and/or exacerbated by viruses, bacteria, or parasitic infectious agents. Pathogens can activate innate immune response interacting with Toll-like receptors that recognize pathogen-associated molecules. As a consequence of infections, a prolonged inflammatory response may occur leading to chronic inflammation with activation of adaptive immune response. In addition, the defective clearance of apoptotic infected cells, which progress- es to secondary necrosis, can foster the autoimmune reactions. Although numerous data from humans and/or animal models support the hypothesis of a direct contribution of pathogens to the induction of the disease, some infectious agents are able to prevent autoimmune disorders. In this review, data on the innate and adaptive immune response induced by pathogens are summarized, focusing on the possible protective or non-protective role of infections in the development of autoimmune diseases.

Abstract
The relationship between infection and autoimmunity has been increasingly defined over the last twenty years or so. It is now quite clear that, in genetically susceptible individuals, environmental factors (mainly infections) play a critical role in the pathogenesis of autoimmune diseases. It is believed that infections contribute to the maturation of the immune system from the innate to adoptive phases, and that bacterial and viral infections are arthritogenic stimulants leading to various rheumatic conditions. A failure to isolate these microorganisms is probably due to the action of the immune system, but often casts doubt on their role in the pathogenesis of autoimmune diseases. Among bacteria, Helicobacter pylori has been associated with diseases such as autoimmune gastritis, Sjögren's syndrome, atherosclerosis, immune thrombocytopenia purpura, inflammatory bowel diseases and autoimmune pancreatitis, in each of which it seems to play a pathogenatic, but it has also been suggested that it may help to protect against the development of autoimmune gastritis, multiple sclerosis, systemic lupus erythemathosus and inflammatory bowel diseases. Infectious agents may play a dual role in the etiopathogenesis of antiphospholipid syndrome (APS): they may be the initial trigger of the production of antibodies cross-reacting with beta 2 glycoprotein I (Beta2GPI) and infectious peptides, and also induce an inflammatory response. According to the two-hit theory, pathogenetic anti-Beta2GPI antibodies act as the first hit whereas inflammatory responses may represent the second hit The slowly growing Propionibacterium acnes may be involved in the etiopathogenesis of SAPHO syndrome non-specific activation of cell-mediated immunity. Its ability to persist in bone lesions in a form that is incompatible with culturing suggests the possibility an arthritis that is secondary to a "persistent" infection.

Abstract
The problem of infectious pathology is quite actual for state-of-the-art rheumatology. Various infectious agents take part in the development of rheumatic diseases (RD), playing a trigger role and launching immune mechanisms of inflammation. Besides, comorbid infection often complicates the RD course due to the immune status disorders connected with a background disease and the use of immunosuppressive drugs. Treatment of such pathology is an important task. The main data on frequency and localization of infections in RD are represented. The authors also proved necessity of clinical researches with the aim of development of optimal antimicrobial therapy and prophylaxis of infections in RD patients.

Abstract
Autoimmune rheumatic diseases are generally considered as a multifactorial aetiology, mainly genetic susceptibility combined with environmental triggers of which bacteria are considered one of the most prominent. Among the rheumatic diseases where bacterial agents are more clearly involved as triggers are: reactive arthritis (ReA), rheumatic fever (RF) and Lyme disease. The role of bacterial infections in inducing other seronegative spondyloarthritis and antiphospholipid antibody syndrome has been hypothesized but is still not proven. The classic form of ReA is associated with the presence of HLA-B27 and is triggered by the urethritis or enteritis causing pathogens Chlamydia trachomatis and the enterobacteria Salmonella, Shigella, and Yersinia, respectively. But several other pathogens such as Brucella, Leptospira, Mycobacteria, Neisseria, Staphylococcus and Streptococcus have also been reported to cause ReA. RF is due to an autoimmune reaction triggered by an untreated throat infection by Streptococcus pyogenes in susceptible individuals. Carditis is the most serious manifestation of RF and HLA-DR7 is predominantly observed in the development of valvular lesions. Lyme disease is a tick-transmitted disease caused by the spirochete Borrelia burgdorferi. Knowledge is limited about how this spirochete interacts with human tissues and cells. Some data report that Borrelia burgdorferi can manipulate resident cells towards a pro- but also anti-inflammatory reaction and persist over a long period of time inside the human body or even inside human cells.

Abstract
INTRODUCTION Latent tuberculosis infection (LTBI) is detected with the tuberculin skin test (TST) before anti-TNF therapy. We aimed to investigate in vitro blood assays with TB-specific antigens (CFP-10, ESAT-6), in immune-mediated inflammatory diseases (IMID) for LTBI screening. PATIENTS AND METHODS Sixty-eight IMID patients with (n = 35) or without (n = 33) LTBI according to clinico-radiographic findings or TST results (10 mm cutoff value) underwent cell proliferation assessed by thymidine incorporation and PKH-26 dilution assays, and IFNgamma-release enzyme-linked immunosorbent spot (ELISPOT) assays with TB-specific antigens. RESULTS In vitro blood assays gave higher positive results in patients with LTBI than without (p<0.05), with some variations between tests. Among the 13 patients with LTBI diagnosed independently of TST results, 5 had a negative TST (38.5%) and only 2 a negative blood assays result (15.4%). The 5 LTBI patients with negative TST results all had positive blood assays results. Ten patients without LTBI but with intermediate TST results (6-10 mm) had no different result than patients with TST result </=5 mm (p>0.3) and lower results than those with LTBI (p<0.05) on CFP-10+ESAT-6 ELISPOT and CFP-10 proliferation assays. CONCLUSION Anti-TB blood assays are beneficial for LTBI diagnosis in IMID. Compared with TST, they show a better sensitivity, as seen by positive results in 5 patients with certain LTBI and negative TST, and better specificity, as seen by negative results in most patients with intermediate TST as the only criteria of LTBI. In the absence of clinico-radiographic findings for LTBI, blood assays could replace TST for antibiotherapy decision before anti-TNF.

Abstract
We summarized most of the rheumatologic manifestations of tuberculosis (TB) and the occurrence of Mycobacterium tuberculosis disease associated with rheumatologic diseases. We established 4 different categories: (1) direct musculoskeletal involvement of M. tuberculosis, including spondylitis, osteomyelitis, septic arthritis, and tenosynovitis; (2) M. tuberculosis as an infectious pathogen in rheumatologic diseases, particularly with the use of newer agents such as tumor necrosis factor-alpha inhibitors; (3) antimycobacterial drug-induced rheumatologic syndromes, including tendinopathy, drug-induced lupus, and others; and (4) reactive immunologic phenomena caused by TB, such as reactive arthritis, erythema nodosum, and others. In addition, Bacille-Calmette-Guérin vaccination used for the prevention of TB or as a chemotherapeutic agent for bladder carcinoma also may be associated with musculoskeletal adverse events. We conclude that M. tuberculosis can directly or indirectly affect the musculoskeletal system.

Abstract
The genetic diversity of group A streptococcal (GAS) isolates obtained in 1990 from Ethiopian children with various streptococcal diseases was studied by using emm gene sequence analysis. A total of 217 GAS isolates were included: 155 and 62 isolates from throat and skin, respectively. A total of 78 different emm/st types were detected among the 217 isolates. Of these, 166 (76.5%) belonged to 52 validated reference emm types, 26 (11.9%) belonged to 16 already recognized sequence types (st types) and 25 (11.5%) belonged to 10 undocumented new sequence types. Resistance to tetracycline (148 of 217) was not correlated to emm type. Isolation rate of the classical rheumatogenic and nephritogenic strains was low from cases of acute rheumatic fever (ARF) and acute glomerulonephritis (AGN), respectively. Instead, the recently discovered st types were overrepresented among isolates from patients with ARF (3 of 7) and AGN (9 of 16) (P < 0.01) compared to isolates from subjects with tonsillitis and from healthy carriers (10 of 57 and 16 of 90, respectively). In contrast to rheumatogenic strains from the temperate regions, more than half of the isolates from ARF (four of seven) carried the genetic marker for skin preference, emm pattern D, although most of them (six of seven) were isolated from throat. Of 57 tonsillitis-associated isolates, 16 (28%) belonged to emm pattern D compared to <1% in temperate regions. As in other reports emm patterns A to C were strongly associated with throat, whereas emm pattern D did not correlate to skin. This first large-scale emm typing report from Africa has demonstrated a heterogeneous GAS population and contrasting nature of GAS epidemiology in the region.

Abstract
The paper contains the generalized many-year research conducted by staff of the chair for microbiology (including virology and immunology) aimed at describing the universal principles related with forming an inter-individual diversity of gastric-and-intestinal micro-biocenosis. The research demonstrated a high dependence of qualitative and quantitative parameters of the analyzed biotope on various-genesis factors. It was established that the nature of violations in the gastric-and-intestinal micro-biocenosis is not dependent on peculiarities of an influencing pathogenetic factor, and its difference is related only with quantitative and qualitative (specific) changes in the microbial composition. The marked feature makes it possible to regard the gastric-and-intestinal micro-biocenosis as a non-specific indicator of the condition of a macro-organism and that of the environmental quality.

Abstract
The separate contribution of NSAIDs and H. pylori in the pathogenesis of peptic ulcer disease has not been fully elucidated. The aim of this study was to investigate the seroprevalence of H. pylori in patients with rheumatic diseases and chronic NSAID treatment. Patients with a rheumatic disease, age 40-80 years, and regular use of NSAIDs (at least 3 times a week) were included (n= 1214). IgG-antibodies to H. pylori were found in 39% and increased gradually with age: from 25% in patients in the 40-50 years age group to 48% in patients aged 70-80 years (p<0.0001). No difference was observed between men and women, or between the three centres. In our population of rheumatic patients treated with NSAIDs the seroprevalence of H. pylori is substantial (39%), but seems to be lower than in previous reports, which may be due to a cohort effect.

Abstract
The aim of the present study was to determine the prevalence of Helicobacter pylori infection in a group of patients hospitalized at the clinic of rheumatology who presented peptic ulcers and erosions associated with nonsteroidal antiinflammatory drugs (NSAIDs). Of a group of 4,256 hospitalized patients receiving therapy with NSAIDs, 221 patients with persistent dyspepsia underwent endoscopic examination of the upper segment of the gastrointestinal tract. Among them, mucosal abnormalities in the stomach and duodenum were confirmed in 69 patients. H. pylori was found in 42% (29/69) of the examined patients. Peptic ulcers were confirmed in 19 patients. Localization was gastric in 12 patients and duodenal in seven. H. pylori was found in only 17% of the patients (2/12) with gastric ulcers, but in as many as 86% (6/7) of those with duodenal ulcers. Patients with H. pylori taking NSAIDs were at higher risk of developing duodenal mucosal abnormalities, both ulcers (OR: 10.17; 95% CI: 1.08-23.88, p = 0.013) and erosions (OR: 2.67; 95 CI: 1.94-3.66, p = 0.001). Concomitant administration of corticoids and NSAIDs did not increase the risk of gastrotoxicity in patients with positive finding of H. pylori (OR: 0.32; 95% CI: 0.1-0.96). In conclusion, a close association was found between H. pylori infection and duodenal ulcers and erosions, but not between gastric ulcers and gastric erosions in a group of patients hospitalized for rheumatic diseases and undergoing NSAID therapy.

Abstract
PURPOSE Lyme borreliosis is a multisystemic infection caused by the spirochaete Borrelia burgdorferi. In European endemic areas like northeast France, articular manifestations are, after neuroborreliosis, the most frequent extra-cutaneous features observed. Among the pathogenic species of Borrelia, Borrelia burgdorferi sensu stricto is the most frequently identified during Lyme arthritis, but others species also seem to be involved. CURRENT KNOWLEDGE AND KEY POINTS The diagnosis of Lyme arthritis is usually based on combined clinical data and serological laboratory tests. In atypical forms, detection of bacterial DNA could be useful. While mechanisms involved in acute Lyme arthritis are beginning to be better understood, the pathogenesis of chronic arthritis, which concerns about 10% of the patients, remains unknown. Two hypotheses are proposed to explain the prolonged evolution of the articular disease: a chronic persistence of Borrelia burgdorferi, which evades the host immune system within the joint and/or an autoimmune mechanism by molecular mimicry. The antibiotic therapy is codified in acute arthritis, but is not really adapted in chronic Lyme arthritis or post-Lyme syndrome. FUTURE PROSPECTS AND PROJECTS To prevent the disease, the vaccine available in the United States does not offer complete protection and is not useful in Europe since the species heterogeneity is important for the outer surface protein A. A better understanding of Lyme disease pathogenesis can subsequently lead to new therapeutic or preventive approaches.

Abstract
Infective endocarditis (IE) is due to a microbial infection of the heart valves or of the endocardium in close proximity to either congenital or acquired cardiac defects. This infection is associated with a high risk of complications. Rheumatic manifestations are known to be frequent complications of IE. Controversy, however, frequently exists about the actual incidence of these complications. This may be due to the small number of series describing the frequency and type of rheumatic manifestations, the absence of uniform criteria used for the diagnosis of IE, and the fact that some studies on rheumatic manifestations in IE have been described from tertiary referral centers, which implicates associated problems of referral bias and uncertainty of denominator population. To investigate further the incidence, clinical spectrum, and outcome of patients with IE and rheumatic manifestations, we examined the features of patients diagnosed with clinically definite IE according to the Duke classification criteria at the single reference hospital for a defined population in northwestern Spain during a 12-year period. Between 1987 and 1998, 100 consecutive patients had 110 episodes of clinically definite IE. Rheumatic manifestations were observed in 46 of the 110 episodes (41.8%). As in other western countries, they occurred more commonly in men aged in their 50s. The most frequent valve involved was the aortic (43.5%) followed by the mitral valve (30.4%). Myalgia was a frequent symptom. Peripheral arthritis, generally as monoarthritis, was clinically evident in 15 cases (13.6%), and sacroiliitis in 1 patient. Low back pain was described in 14 cases (12.7%). Septic discitis was observed in 2 cases, and biopsy-proved cutaneous leukocytoclastic vasculitis was found in 4 cases. Other conditions such as trochanteric bursitis and polymyalgia were observed in 2 and 1 case, respectively. Apart from a significantly higher frequency of hematuria and a trend to lower serum complement levels in patients with rheumatic complications, no differences in clinical features, laboratory tests, or microbiologic blood culture results were found between cases with IE with or without rheumatic manifestations. Also, although patients with rheumatic manifestations had more embolic complications, the inhospital mortality rate in patients with rheumatic manifestations was not significantly different from that of the rest of the patients. The present study supports the claim that rheumatic complications are frequent in patients with clinically definite IE from southern Europe. The presence of musculoskeletal or vasculitic manifestations may be of some help, as warning signs, for the recognition of patients with severe disease who require rapid diagnosis and therapy.

Abstract
The proteins in the cell wall of Streptococcus have many functions, with some proteins being regarded as a marker of their rheumatological potential. High levels of antibodies directed against some proteins are seen in patients with acute rheumatic fever. The theory of molecular mimicry forms the basis of the relationship between the bacteria and the disease acute rheumatic fever. A distinct entity which does not fulfil Jones' criteria, and which is known as post-streptococcal reactive arthritis following infection with beta-haemolytic streptococci, is being encountered more frequently. A pyogenic form of arthritis due to Streptococcus is one of the most common and serious joint infections and requires prompt recognition and treatment.

Abstract
Ankylosing enthesopathy (ANKENT) is a naturally occurring joint disease in mice with numerous parallels to human ankylosing spondylitis (AS). Similarities between AS and ANKENT include not only affected tissue (joint entheses) but also association of the disease with genetic background, including MHC genes, gender, and age. Young males with the C57Bl/10 background have been described to suffer from ANKENT and, among H-2 congenic strains, high frequency of afflicted joints has been recorded in B10.BR (H-2(k)) males. Interestingly, the incidence of ANKENT is higher in conventional (CV) males that in their specific-pathogen-free (SPF) counterparts. The latter finding suggests that microbes could play a role as an ANKENT-triggering agent. To further examine this hypothesis we have established a germ-free (GF) colony of B10.BR mice and observed ANKENT incidence in both GF males and their conventionalized (ex-GF) male littermates; 20% of ex-GF males developed ANKENT before 1 year of age. In contrast, no joint disease was observed under GF conditions (p < 0.0001). Our results show that live microflora is required in ANKENT pathogenesis.

Abstract
Helicobacter pylori infection is linked to conditions of the upper gastrointestinal tract, including peptic ulcer and gastric adenocarcinoma. It has also been associated with a wide variety of non-gastrointestinal tract conditions. However, the evidence in support of H. pylori infection as a cause of the non-gastrointestinal tract conditions is not widely understood. We reviewed the medical literature for publications and abstracts dealing with putative non-gastrointestinal tract associations of H. pylori infection. We appraised the level of evidence and applied it to an established set of 9 criteria for determining causation. We found that many studies examining a possible causal relationship have been uncontrolled or inadequately controlled. Studies have often failed to control for socioeconomic status. Studies of treating H. pylori infection in patients with these disorders have been poorly designed and inappropriately controlled, and therefore add little to the evidence base. Attention should be focused on appropriate testing for and treatment of H. pylori infection in patients with conditions that are of proven association, notably peptic ulcer disease.

Abstract
There are many different rheumatic symptoms of gastrointestinal (GI) disorders and a whole range of GI symptoms that occur in rheumatologic disorders. Spondyloarthropathies (SpA) are closely related to the GI tract. Bacterial DNA has been detected in peripheral but not the sacroiliac joints of patients, including enterobacteria; the significance of this finding is not clear yet because antibiotic therapy seems not to be effective. The synovial lymphocyte proliferation of reactive arthritis (ReA) patients to the 60-kD heat-shock protein of Yersinia plays a major role in the immune response. Anti-Klebsiella antibodies are associated with gut lesions in SpA; their significance for the pathogenesis of SpA remains uncertain. ReA patients seem to have an impaired TH1-cytokine response, which might contribute to disease persistence. HLA B27-positive subjects seem to have a low tumor necrosis factor-alpha secretor status, possibly leading to diminished immune responses against certain microbes. In patients with Whipple's disease, Tropheryma whippelii can be cultured from gut biopsy specimens when interleukin-4 is added. The gene for hemochromatosis has been identified. Hepatitis C virus DNA can be found in many patients with cryoglobulinemia. Treatment with interferon-alpha might help in some patients. Effective treatment for primary biliary cirrhosis with ursodeoxycholic acid is not helpful for rheumatic symptoms. The severity of esophageal dysfunction in systemic sclerosis does not correlate with symptoms. GI symptoms do, although not frequently, occur in vasculitides.

Abstract
At the end of the nineteenth century, the field of microbiology was born, and the infectious nature of many previously unexplained diseases was illuminated as powerful new technology was applied. At the end of the twentieth century, the etiology of myriad chronic diseases remains unexplained. We have argued that many of these diseases have clinical, epidemiological, and pathological features that suggest a role for microbes in their pathogenesis. Although definitive evidence of microbial disease causation is lacking, we believe that new technologies, such as sequence-based microbial identification, will successfully be applied to many of these chronic idiopathic diseases in the near future. As novel pathogens and previously described pathogens are revealed as the causative agents for some of these conditions, new diagnostic, preventive, and therapeutic modalities may emerge, transforming some diseases from idiopathic and chronic, to infectious and curable.

Abstract
Infectious diseases continue to elicit worldwide attention. Many of these diseases have rheumatic manifestations as an incidental or principal feature. Because this is particularly true in children, rheumatic manifestations of infectious diseases in this population continue to be an area of great importance to rheumatologists. A variety of bacteria, viruses, fungi, and parasitic organisms can give rise to infectious diseases with rheumatic manifestations. A high index of clinical suspicion is frequently necessary for an accurate diagnosis. Prompt diagnosis and early and appropriate therapeutic intervention are usually required for a successful, and frequently curative, outcome. Over the past year, studies have addressed the pathogenetic mechanisms and clinical spectrum of the rheumatic manifestations of infectious diseases in children. There has been particular emphasis on septic arthritis, osteomyelitis, sickle-cell disease, and hepatitis C viral infection. There remains the daunting and unfortunate possibility of large numbers of children developing HIV-associated arthritis.

Abstract
OBJECTIVE To investigate the incidence and risk factors of Mycobacterium tuberculosis infection in longterm corticosteroid treated rheumatic disease patients. METHODS We assessed retrospectively the incidence of active tuberculosis and its risk factors in 269 rheumatic disease patients treated with moderate to high doses of corticosteroid for an evaluation period representing 1,035 corticosteroid years of therapy. RESULTS The mean daily dose of steroid was 18.7 mg prednisolone and the mean daily dose during the first year of treatment was 20.4 mg prednisolone. 21 of these patients developed active tuberculosis resulting in an incidence rate of 20/1,000 patient-years. Cumulative and mean daily steroid doses during the follow-up period and during the first year of treatment, and a history of steroid pulse therapy were significantly correlated with the development of tuberculosis. A past history of tuberculosis, initial chest P-A abnormality, the starting dose of steroid, a history of more than 30 mg/day of prednisolone for more than one month, and a history of cytotoxic therapy were not related to the development of tuberculosis. CONCLUSION The incidence of active tuberculosis is increased in rheumatic patients on moderate-to-high dose steroid treatment. Its risk factors are the cumulative and mean daily steroid doses during the follow-up period and during the first year of steroid treatment, and a history of steroid pulse therapy.

Abstract
The objective was to investigate the presence of mycoplasmas in rheumatoid arthritis (RA) and other chronic arthritides. Samples of synovial fluid (SF) were systematically collected from all patients presenting with an articular effusion. Each sample was divided into three parts. The first was kept for cytological count and culture on standard media for pyogens and mycobacteria, the second was cultivated on specific media for mycoplasmas and the third frozen for subsequent study by polymerase chain reaction (PCR). A total of 209 samples were studied. Half of the patients had inflammatory rheumatic diseases: RA (27), spondyloarthropathy (28), connective tissue disease (5), unclassified arthritis (45). The remaining suffered from other conditions, including osteoarthritis (60), gouty arthritis (19), haemarthrosis (5), post-traumatic effusion (2). Eight samples were positive by culture, two for Mycoplasma hominis; three for M. fermentans, one for M. salivarium, one for M. orale and one for Ureaplasma urealyticum. All the patients concerned had an inflammatory rheumatic disease: five had RA, one had psoriatic arthritis and two had unclassified arthritis. These results were confirmed by PCR in two cases (one M. fermentans, one U. urealyticum). The lack of sensitivity of the conventional PCR assay on SF is discussed. Mycoplasmas were mainly detected in SF of RA patients. These results raise the question of the possible role of mycoplasmas in the triggering and maintenance of inflammatory rheumatic diseases, especially RA.

Abstract
The acute effects of foodborne disease are sometimes not the end of the illness. Several significant foodborne pathogens are capable of triggering chronic disease, and even permanent tissue or organ destruction, probably via immune mechanisms. Arthritis, septic and reactive, inflammatory bowel disease, haemolytic uraemic syndrome, Guillain-Barré syndrome, and possible several autoimmune disorders can be triggered by foodborne pathogens or their toxins. Research is needed to more fully understand the mechanisms by which the immune system is inappropriately activated by these common foodborne disease-causing agents.

Abstract
AIM/BACKGROUND Mycoplasmas, especially Mycoplasma fermentans, were suggested more than 20 years ago as a possible cause of rheumatoid arthritis but this hypothesis was never substantiated. In view of the superior sensitivity of the polymerase chain reaction (PCR) assay over culture, the aim was to use this method to seek M fermentans and M penetrans in synovial samples from patients with various arthritides. METHODS Synovial fluid samples (n = 154) and synovial biopsy specimens (n = 20) from 133 patients with various rheumatic disorders were stored at -80 degrees C for between one and 40 months. Aliquots (500 microliters) of the synovial fluid samples were centrifuged and the deposit, and also the synovial biopsy specimens (approximately 1 g) were placed in lysis buffer with proteinase K for DNA extraction. The DNA was tested by using a semi-nested PCR assay for M fermentans and a single-round PCR for M penetrans. RESULTS M fermentans was detected in the joints of eight (21%) of 38 patients with rheumatoid arthritis, two (20%) of 10 patients with spondyloarthropathy with peripheral arthritis, one (20%) of five patients with psoriatic arthritis, and four (13%) of 31 patients with unclassified arthritis. M fermentans was not found in the joints of the seven patients with reactive arthritis, the 29 with osteoarthritis or post-traumatic hydrarthrosis, the nine with gouty arthritis, nor the four with chronic juvenile arthritis. M penetrans was not detected in any sample. CONCLUSIONS These findings show that the presence of M fermentans in the joint is associated with inflammatory rheumatic disorders of unknown cause, including rheumatoid arthritis. However, whether this organism triggers or perpetuates disease of behaves as a passenger remains conjectural.

Abstract
The collection of moderate phages of S. pyogenes, group A, had been created earlier. As shown in this work, group A streptococcal cultures isolated from patients with rheumatism, glomerulonephritis and tonsillitis exhibited different sensitivity to the phages of this collection: the cultures were lyzed by phages of groups II and III in rheumatism, group III in tonsillitis and group I in glomerulonephritis. The study revealed that lysogeny was widely spread among S. pyogenes strains isolated from patients with different diseases under study. Most frequently occurred among cultures isolated from tonsillitis patients. In this disease only phage-resistant streptococcal cultures proved to be lysogenic. Lysogeny was found among both phage-sensitive and phage-resistant cultures in rheumatism and especially in glomerulonephritis.

Abstract
Campylobacter jejuni is an almost ubiquitous, microaerophilic, gram-negative rod. Outbreaks have been associated with drinking raw milk or contaminated water and eating poultry. Campylobacter jejuni accounts for 3.2% to 6.1% of cases of diarrheal illness in the general population of the United States, and infected patients frequently present with abdominal pain and fever. Less frequently, C jejuni is responsible for bacteremia, septic arthritis, septic abortion, and other extraintestinal infections. Reactive arthritis, Reiter's syndrome, the Guillain-Barré syndrome, and pancreatitis may accompany or follow C jejuni enterocolitis. Campylobacter jejuni is an important cause of diarrheal illness and is a more commonly identified stool organism than Salmonella or Shigella species. Recurrent and chronic infection is generally reported in immunocompromised hosts.

Abstract
Biopsy material of gastric mucosa obtained from 94 patients with rheumatic diseases was subjected to bacterioscopic, biochemical and microbiological studies. Helicobacter pylori was found in 29% of patients with rheumatism, in 34.3% of patients with rheumatic arthritis and in 39.9% of those suffering from osteoarthrosis deformans. The study confirms that the microorganisms found in gastric and duodenal mucosa should be considered as a saprophytic microflora which promotes inflammatory process.

Abstract
Results of the study of incidence of chlamydia trachomatis infection in patients with Reiters syndrome are presented. Chlamydia trachomatic was isolated from the uretral smear in 12 (34.28%) of 35 patients with Reiter's syndrome. In the group of patients with other rheumatologic diseases Chlamydia trachomatis was isolated in 2 (5.13%) of 39 patients. In all patients with negative isolation, infection was confirmed serologically also and in some patients with negative isolation it was also proved.

Abstract
In spite of increasing evidence that viruses and especially retroviruses could act as etiologic factors in autoimmune and especially autoimmune rheumatic diseases, clear-cut evidence for an involvement of these agents is still missing. Findings, which, for example, indirectly support the hypothesis that retroviruses might play a part, are the demonstration of antibodies to the gp24 in SLE and Sjögren's patients as well as the description of retroviral antigens in the inflamed synovium of rheumatoid arthritis patients. Furthermore, evidence comes from animal models that viruses, such as the Visna or Caprine arthritis encephalitis virus, induced chronic inflammatory diseases in sheep and goats. More recently, a mouse model for rheumatoid arthritis and Sjögren's syndrome was reported in mice transgenic for HTLV-1tax. It is hoped that, especially from the experimental animal models, the possible role of retroviruses as etiological factors in autoimmune rheumatic diseases can be clarified.
