    Notes: Abstract Hyaluronic acid (HA) isolated from synovial fluid by CsCl density-gradient ultracentrifugation show a decrease in the viscoelasticity. Metrizamide, a substance used recently for non-ionic density-gradient ultracentrifugation, do not change the rheology of synovial fluid and HA. Thus it may be possible to isolate HA without altering rheological properties.

    Notes: Summary Mononuclear cell preparations from peripheral blood (PBL) and synovial fluid (SFL) of 27 Patients with rheumatoid diseases (15 patients with definite rheumatoid arthritis (RA), 10 with other inflammatory joint diseases (OJD), 1 with sarcoid arthritis (SA) and 1 with traumatic arthritis (TA) were examined for lymphocyte subpopulations determined by monoclonal antibodies of the OKT series and by the dot-like, acid α-naphthyl esterase staining (ANAE) activity. In patients with classic, active RA, blood T cells carrying the OKT8+ (suppressor/killer) phenotype were significantly reduced leading to an elevated OKT4/OKT8 ratio of 4.1±0.4 compared with 2.1±0.1 in healthy controls. In 10 patients with OJD this diminution of OKT8+ cells in peripheral blood was less pronounced or absent. As regards SFL subpopulations, patients with RA and OJD exhibited a similar distribution pattern with an elevation of OKT8+, Ia+ and ANAE negative cells and a similar OKT4/OKT8 ratio of 1.5±0.3 and 1.6±0.4, respectively. Similar results were also obtained in the only patient with TA, whereas the patient with SA and one RA patient with relapse after surgical synovectomy exhibited high OKT4/OKT8 ratios, both in synovial fluid and peripheral blood. Neither the OKT markers nor the dot-like ANAE staining pattern were significantly correlated to parameters of systemic or local disease activity as estimated by erythrocyte sedimentation rate and a local disease activity index.

    Description / Table of Contents: Summary 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.
    Notes: Zusammenfassung Bei der Katzenkratzkrankheit (KKK) handelt es sich um eine in Deutschland wenig bekannte Infektionskrankheit. Erst vor wenigen Jahren konnte der Erreger, Bartonella henselae, isoliert werden. In der Mehrzahl der Fälle findet sich ein typisches Krankheitsbild mit Hautveränderungen im Bereich von Katzenbiß- oder Kratzwunden und einer benignen Lymphadenopathie. Weniger häufig kommt es zu weiteren Organmanifestationen. Wir berichten über eine 47-jährige Patientin, die nach einem Katzenbiß eine reaktive Spondarthritis mit Synovialitiden der Fingergelenke, Polyarthralgien der mittleren und großen Gelenke und entzündliche Lumbalgien entwickelte. Die rheumatische Symptomatik war zeitlich limitiert und sprach gut auf NSAR an. Bislang sind nur wenige Fälle von Gelenkbeteiligung im Rahmen einer KKK beschrieben worden. Da die Durchseuchung von Katzen mit Bartonella henselae in Europa jedoch hoch ist, könnte es sich um eine häufigere Ursache von Gelenkbeschwerden handeln, als bislang angenommen. Die Diagnostik der KKK wurde in den letzten Jahren durch die Entwicklung serologischer Teste erleichtert. Wir geben einen Überblick über die klinischen Manifestationen und fassen die diagnostischen Kriterien dieser Erkrankung zusammen.

    Notes: Summary Diagnosis of arthritis with recent onset is still an unresolved problem. In 1984 we started an outpatient clinic for patients with early arthritis of less than one year duration. Of a total of 226 patients seen 149 (66%) had definite (n=76; 34%) or probable (n=73; 32%) inflammatory rheumatic disease, and 77 (34%) had degenerative or extraarticular rheumatic disease. Thirtynine patients were classified as undifferentiated arthritis. This undefined arthritis was often monoarticular (12%) and oligoarticuler (44%). One patient met 5 ARA-criteria for rheumatoid arthritis, 14 (36%) met 3–4 ARA-criteria and 25 (64%) only 1–2 ARA-criteria. ESR was elevated in only 23 (59%) patients, rheumatoid factor was positive in 7 (19%) patients and HLA-B27 was positive in 9 (23%) patients. Seventeen (44%) patients had a history of recent infections preceding the beginning of joint symptoms. Thus undifferentiated arthritis represents a heterogeneous group of diseases. Despite diagnostic progresses in recent years a high proportion of early arthritis cannot be diagnosed definitely.
