Comparing 10-day and 4-month doxycycline courses for treatment of Chlamydia trachomatis-reactive arthritis: a prospective, double-blind trial.

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.

Chlamydia and Borrelia DNA in synovial fluid of patients with early undifferentiated oligoarthritis: results of a prospective study.

OBJECTIVE: More than 50% of patients with synovitis involving 1-4 joints remain classified as having undifferentiated oligoarthritis (UOA) after 1 year of disease. The clinical presentation is often similar to that of reactive arthritis (ReA) and other spondylarthropathies or to Lyme arthritis. We therefore determined how often Chlamydia trachomatis (Ct) and Borrelia burgdorferi (Bb) can be identified in patients with UOA, by using an extensive laboratory approach. METHODS: We prospectively studied 52 patients with UOA who presented at an early synovitis clinic in a region highly endemic for Lyme disease. Patients were examined by standardized clinical and immunoserologic procedures. Synovial fluid was screened for the presence of Ct and Bb DNA by polymerase chain reaction (PCR). Urine was tested for Ct DNA by ligase chain reaction, and serum was tested for Ct antibodies by enzyme-linked immunosorbent assay and Bb antibodies by hemagglutination test and Western blotting. PCR results in the UOA patients were compared with the results in cohorts of patients with definite rheumatoid arthritis (RA), Lyme arthritis, and Chlamydia-induced arthritis (CIA). RESULTS: In the synovial fluid of 9 of 52 patients with UOA (17%), we found Ct DNA, and in 6 of the 52 patients (12%), Bb DNA was found. The frequency of bacteria-specific DNA was 50% (7 of 14) in CIA patients and 69% (11 of 16) in patients with Lyme arthritis. No Bb or Ct DNA was found in the synovial fluid of the 31 RA patients. CONCLUSION: With optimized PCR protocols, it is possible to detect considerable levels of Bb and Ct DNA in the synovial fluid of patients with UOA. Although the presence of bacterial DNA does not unequivocally prove its etiologic significance, we suggest that at least one-third of patients with UOA may have a form of ReA that involves asymptomatic primary infection.

[Combined basic therapeutic drugs. From individual hope to targeted use].

Accumulating evidence suggests that treatment of rheumatoid arthritis (RA) with two or more disease-modifying antirheumatic drugs (DMARDs) is more efficient than single agent therapy. Randomized clinical trials demonstrated the efficacy of various combinations such as methotrexate plus sulfasalazine plus hydroxychloroquine, methotrexate plus ciclosporine or methotrexate plus infliximab, respectively. In contrast to these data, however, most German rheumatologists use combination therapy in a small percentage of patients with active RA. Thus, consensus criteria should be defined when and how to use combination therapy in the treatment of active disease. We suggest that combination therapy should be started if active disease is still present after three months of treatment with a single standard DMARD, mostly methotrexate, plus low dose prednisolone and that combination DMARD therapy should be used before TNF blocking agents.

Intra-articular co-infection by Borrelia burgdorferi and Chlamydia trachomatis.

OBJECTIVE: Chlamydia trachomatis and Borrelia burgdorferi infections are frequently the cause of unexplained oligoarthritis, as shown by identification of bacteria specific DNA in joint material from patients with reactive arthritis, Lyme arthritis, and undifferentiated oligoarthritis. The aim of this study was to determine whether the two organisms occur simultaneously in joint material from patients with arthritis. METHODS: Seventy six patients with unexplained arthritis were prospectively studied. Synovial fluid was obtained from all patients and examined for DNA from C trachomatis and B burgdorferi using specific polymerase chain reaction (PCR) protocols. Data concerning prior genitourinary infection or a history of tick bite were recorded and serum antibodies to C trachomatis and B burgdorferi were determined. RESULTS: Six patients (8%) had DNA from both C trachomatis and B burgdorferi in the same synovial fluid specimen (mean leucocyte count 11.925/mm(3), 65% granulocytes). These patients (four men, two women; mean age 33.7 years) all had oligoarthritis of the knee, ankle, or both (mean disease duration 11.3 months). From the history and serological examination, four patients had some evidence of actual or previous infection with one or other of the bacteria, while the other two patients had a positive serological test for Chlamydia only. CONCLUSIONS: DNA from two different microorganisms which are known to be triggering agents for arthritis may be present simultaneously in joint material from patients with unexplained oligoarthritis. This finding raises the question as to whether, in such cases, one or both bacteria contribute to the pathogenesis of the disease or whether they are only innocent bystanders.

Disability and handicap in rheumatoid arthritis and ankylosing spondylitis--results from the German rheumatological database. German Collaborative Arthritis Centers.

OBJECTIVE: To describe indicators of disability and handicap in the 2 major inflammatory rheumatic diseases rheumatoid arthritis (RA) and ankylosing spondylitis (AS) and to estimate the burden of illness in terms of functional status, pain, and global well being, as well as with regard to unemployment and early retirement. METHODS: Data from the German rheumatological database on 52,444 patients with RA and 8,776 patients with AS seen at 21 collaborative arthritis centers in Germany between 1993 and 1997 were analyzed. To estimate the burden of the 2 diseases at different biographical phases, age and sex matched groups of patients were compared for functional disability, pain, global assessment of health status, education level, and employment status. RESULTS: For comparable ages, disability in female patients with AS or RA was rated similarly by the physicians (e.g., 61-70 years: 42% severe disability in RA and 44% in AS), whereas men with AS were rated more disabled than men with RA (61-70 years: 35% in RA and 48% in AS). Patients' self-ratings of disability were generally worse for women than for men (age 61-70: women 37% severe disability in RA and 35% in AS, men: 24% in RA and 19% in AS). Pain intensity was rated similarly by women and men with RA and AS at ages < 51 years (33% severe pain at ages 41-50 in men and 34% in women in both diseases). It increased with age in women (> 70 years: 41% severe pain in RA and 44% in AS) and remained stable in men (27% RA and 29% AS > 70 years). At 71.3% the employment rate in AS was clearly higher than in RA (49.5%). There was significant influence of the education level (men 51-60 years with AS: low education 56% employment rate, high education 79%) and the labor market (men 51-55 years with AS: 80% employment rate under good, 59% under bad overall labor market conditions). CONCLUSION: Age and sex matched groups of patients with RA and AS in tertiary rheumatological care show similar amounts of disability, pain, and reduction in well being. Therefore, the offer of comprehensive care and pain management to both groups should be comparable.

Optimised sample preparation of synovial fluid for detection of Chlamydia trachomatis DNA by polymerase chain reaction.

OBJECTIVE: To optimise sample preparation of synovial fluid for Chlamydia trachomatis (CT) specific polymerase chain reaction (PCR). METHODS: Serial dilutions of purified CT elementary bodies in synovial fluid were prepared. The synovial fluid pellet was processed by eight different methods of sample preparation. Then samples were analysed by CT specific PCR. The sensitivity of PCR was the basis of ranking of the eight different methods. RESULTS: Highest sensitivity was achieved by methods including an additional step of DNA isolation. Additional extraction of protein and polysaccharides by cetyltrimethylammonium bromide (CTAB) increased sensitivity. Addition of hyaluronidase did not increase sensitivity of QIAEX-DNA extraction but was necessary, however, before phenol-chloroform-DNA extraction. CONCLUSIONS: The method of synovial fluid sample preparation significantly influences the sensitivity of subsequent PCR. Additional DNA isolation and extraction of PCR inhibitors by CTAB led to higher sensitivity.

[Reactive arthritis after cat bit: a rare manifestation of cat scratch disease--case report and overview].

Cat scratch disease (CSD) is a rarely recognized infectious disease in Germany. Only a few years ago the causative agent, Bartonella henselae, could be isolated. The typical clinical manifestations of CSD consist of skin changes at the inoculation site and a benign lymphadenopathy; other manifestations are rare. We report the case of a 47 year old woman, who developed a reactive spondylarthropathy with synovitis of finger joints, polyarthralgias of large- and medium-sized joints, and inflammatory spinal pain after a cat bite. The rheumatic manifestations resolved after 10 months by treatment with non-steroidal antirheumatic drugs. Only a few cases of rheumatic manifestations associated with CSD have been described in the literature. Because the prevalence of Bartonella henselae infection of cats is high in Europe, rheumatic manifestations might be more frequent. Diagnosis of CSD is now improved by the development of serological tests. We provide an overview of the clinical manifestations and the diagnostic criteria.

[Continuing education as an instrument of medical quality management].

A rheumatologic educational program for general practitioners (GPs), based on andragogic principles, has been developed by the study group for Continuing Education and Quality Control of the Association of Cooperative Centers of Rheumatology in the DGRh. The educational program has been tested and evaluated by a study group supported by the German Ministry of Health (FB 2-43346-8/63) as an possible tool for quality assurance in rheumatology. Evaluation was carried out in 2 audit circles each of the KV Hessen and KV Lower Saxony. In the 4 audit circles 39 GPs and 3 trained rheumatologists, acting as "experts", participated. Using didactic materials provided by the study group, the topic "shoulder-neck pain" was discussed in all 4 audit circles. Questionnaires and case records according to the topic were used as evaluation tools. The evaluation was supported scientifically by the Scientific Institute of the German Medical Association (WIAD). Of patients with shoulder-neck pain (1193 pre- and 958 post-education) 2151 records were documented by the participating GPs for the evaluation of outcome in respect of changes of diagnostic and therapeutic attitude. Additionally pre- and postintervention, 10 MC questions related to the topic were used to measure changes in specific knowledge, and at the end of the audit circles participants were asked by questionnaire for acceptance of the educational program. An index of acceptance of 9.6 points (best: 7.0 points, worst: 31.0 points) indicating an excellent acceptance of the educational program by the participating GPs was recorded. The increase in specific knowledge amounted to about 30% in all 4 audit circles. Changes in diagnostic and therapeutic attitudes showed a better specification within the spectrum of diagnoses, a reduction of expensive and not indicated diagnostic procedures (e.g., CT), as well as a reduction in the use of non-adequate therapeutic modalities (e.g., massage, fango, unguenta, and gels) in favor of physiotherapy and mobilisation or local and systemic use of corticosteroids. The results of the evaluation project demonstrate that interactive learning in small groups (audit circles) based on andragogic principles can contribute to a better quality of care of patients with rheumatic diseases. The innovative concept seems to be a well-accepted alternative to formal lectures in postgraduate medical education.
