1/90. Whipple's arthritis: direct detection of tropheryma whippelii in synovial fluid and tissue.

    We describe 2 patients presenting with polyarthritis in whom the synovial fluid (1 patient) or synovial tissue (1 patient) was positive for tropheryma whippelii, the Whipple's disease-associated bacillus, when examined by polymerase chain reaction (PCR) and dna sequencing. Histopathologic findings were consistent with articular Whipple's disease in the synovial fluid of 1 patient and the synovial tissue of the other. In both patients, bowel mucosal specimens were negative for Whipple's disease features by histologic and PCR methods. One patient was positive for T whippelii in the peripheral blood. Control synovial fluid specimens from 40 patients with other arthritides, including Lyme arthritis, were negative. Sequencing of a 284-basepair region of the 16S ribosomal rna gene confirmed that the sequence is closely related to the known T whippelii sequence. Both patients responded to treatment with antibiotics. ( info)

2/90. bacillus Calmette-Guerin associated arthropathy mimicking undifferentiated spondyloarthropathy.

    The development of an inflammatory arthritis mimicking an undifferentiated spondyloarthropathy (SpA) was seen in a patient being treated for a superficial bladder cancer with intravesical bacillus Calmette-Guerin (BCG). Physical findings included classic dactylitis of both feet. This is the fourth report identifying a patient with BCG induced articular findings suggestive of a SpA with dactylitis. Studies of BCG stimulated cytokine secretion from peripheral blood mononuclear cells showed the patient to have enhanced interleukin 6 (IL-6) levels and reduced interferon-gamma (IFN-gamma) levels. Spontaneous IL-6 secretion was markedly elevated for the patient, compared to the control subject, but IFN-gamma secretion was quite similar. No differences were apparent with IL-4. ( info)

3/90. pyoderma gangrenosum with secondary pyarthrosis following propylthiouracil.

    The association of pyoderma gangrenosum and arthritic symptoms is well documented. We present a rarely reported variant of this in a 44-year-old woman with pyoderma gangrenosum and bilateral large purulent effusions of her knees. She had no evidence of underlying rheumatoid arthritis or a specific seronegative spondyloarthropathy. Of note she had a history of Graves' disease for which she had been treated with propylthiouracil for 3 years and on investigation at this presentation had a markedly elevated perinuclear antineutrophil cytoplasm antibody (P-ANCA) level with specificities for IgM myeloperoxidase, IgG elastase and IgG lactoferrin. We believe this patient had pyoderma gangrenosum with secondary sterile pyarthrosis and a P-ANCA precipitated by propylthiouracil. ( info)

4/90. Reactive arthritis induced by clostridium difficile enteritis as a complication of helicobacter pylori eradication.

    clostridium difficile has recently been established as a cause of reactive arthritis (ReA). We present a case of clostridium difficile-induced ReA as a complication of helicobacter pylori eradication, which, to the best of our knowledge, is the first such case reported. ( info)

5/90. Clinical and experimental evidence for persistent Yersinia infection in reactive arthritis.

    The findings of bacterial antigens in the joint and persistent triggering infection elsewhere in the body are thought to be important in the pathogenesis of reactive arthritis (ReA). We describe a patient with clinical and laboratory features consistent with this. The initial presentation with erythema nodosum and periarthritis due to infection with yersinia pseudotuberculosis IV was followed 13 months later by recurrent erythema nodosum with joint effusion. At that time, synovial fluid was shown to contain Yersinia antigens, and, surprisingly, Yersinia-specific 16S ribosomal rna (rRNA) sequences were also identified by reverse transcriptase-polymerase chain reaction and sequencing. Since there was no serologic evidence of reinfection, we postulate that a silent persistent Yersinia infection was reactivated, leading to dissemination of organisms to the joint, with consequent induction of ReA. Although the finding of synovial Yersinia antigens years after the original infection in ReA has previously been reported, the presence of Yersinia 16S rRNA indicates that viable organisms were also able to reach the joint.

6/90. Recurrent reactive arthritis associated with urinary tract infection by escherichia coli.

    We describe a patient with recurrent escherichia coli urinary tract infection followed by recurrent reactive arthritis. During a 9 year period the patient developed 4 episodes of arthritis. During each attack, triggering infections were thoroughly investigated but no other causative infection was found. Although the urinary tract is not routinely targeted for triggering infections for reactive arthritis, we suggest that urinary tract infections should be included in the diagnostic investigations of patients with acute arthritis.

7/90. Detection of salmonella infantis in synovial fluid cells of a patient with reactive arthritis.

    We investigated a patient with salmonella infantis triggered reactive arthritis (ReA) for a possible occurrence of S. infantis-specific antigens and dna in the synovial fluid (SF) cells. S. infantis-specific antigens were abundantly observed by immunofluorescence in SF cells of the patient during acute joint inflammation. salmonella-specific dna was detected by Southern blotting of the amplified polymerase chain reaction product once, but the result could not be repeated. It seems that if bacterial dna exists in inflamed joints in salmonella triggered ReA, its amount is extremely low. This is the first report of intraarticular S. infantis antigens and potentially of salmonella dna in salmonella triggered ReA. ( info)

8/90. Beaver fever--a rare cause of reactive arthritis.

    giardia lamblia infection is rarely associated with adult reactive arthritis. We report the first North American case and review the pediatric and adult literature to date. Antimicrobial treatment is essential to eradicate the parasite and control the arthritis. ( info)

9/90. A case of post-streptococcal reactive arthritis.

    Reactive arthritis is a term used to describe a sterile inflammatory arthritis occurring after a documented infection elsewhere in the body. Group A streptococcus is known to cause such an arthropathy in the setting of acute rheumatic fever. Friedberg first postulated that a reactive arthritis might occur in response to a streptococcal pharyngeal infection as a separate entity from rheumatic fever in the 1950s. Then, in the 1980s, other investigators began describing cases of reactive arthritis that were not characteristic of acute rheumatic fever based on certain observations and application of criteria. We present a patient whose clinical features are more consistent with post-streptococcal reactive arthritis than acute rheumatic fever. ( info)

10/90. Reactive arthritis associated with typhoid vaccination in travelers: report of two cases with negative HLA-B27.

    As international travel to developing countries increases, more people seek medical advice concerning food and water-borne diseases, including typhoid fever. Prevention of typhoid fever in high-risk groups (travelers to endemic areas, laboratory workers and household contacts of typhoid carriers) should rely primarily on prevention of exposure. However, immunization is an important adjunct. The decision to immunize against typhoid fever should be individualized, taking into account the benefits versus the risk of possible adverse reactions. Cases of reactive arthritis have been associated with the heat-phenol inactivated 'whole cell' parenteral vaccine, but to our knowledge reactive arthritis has not been previously reported with the oral form (Ty21a). This is a report of HLA-B27 negative reactive arthritis occurring in two travelers after the administration of oral Ty21a typhoid vaccine. ( info)
