    Description / Table of Contents: Summary HCV-infection is an important infectious disease in rheumatology. It is the cause of mixed cryoglobulinemia and other rheumatic manifestations develop frequently during HCV-infection. These comprise: Sicca-syndrome, thromboembolic events associated with anti-cardiolipin antibodies and fibromyalgia. Also associated with HCV-infection is a non-erosive polyarthritis. This synovitis often fulfills the ACR-criteria for rheumatoid arthritis, but the disease course is different with frequent remissions and non-erosive joint involvement. The following autoantibodies are associated with HCV-infection: Cryoglobulins, rheumatoid factor, anti-nuclear antibodies (ANA), anti-smooth muscle antibodies (SMA), anti-phospholipid-antibodies and anti-thyroid-antibodies. In HCV-associated sicca-syndrom, antibodies against Ro (SSA) and La (SSB) are not detected. The course of HCV-infection is often occult, without elevation of liver enzymes. We summarize the clinical and serological signs and symptoms when HCV-infection should be suspected and when HCV-testing should be performed in a rheumatological setting. The identification of HCV-infection in rheumatic patients is important to minimize the risk of aggravating hepatitis by prescription of hepatotoxic drugs and because of the availability of α-interferon as a potential virus eradicating agent.
    Notes: Zusammenfassung Die Hepatitis C-Virus (HCV)-Infektion ist eine für die rheumatologische Praxis relevante Infektionserkrankung. Sie ist Ursache der gemischten Kryoglobulinämie. Zusätzlich entwickeln viele HCV-Patienten rheumatische Begleitmanifestationen. Rheumatologisch relevante Manifestationen sind: Sicca-Syndrom, thromboembolische Ereignisse bei Vorliegen von Anti-Kardiolipin-Antikörpern und Fibromyalgiesyndrom. Ebenfalls HCV-assoziiert, ist eine zumeist seropositive polyartikuläre Arthritis. Diese erfüllt die klinischen Kriterien der chronischen Polyarthritis, nimmt aber einen anderen Verlauf. Remissionen werden häufig beobachtet, erosive Verläufe sind die Ausnahme. Folgende Autoantikörper sind mit der HCV-Infektion assoziiert: Kryoglobuline, Rheumafaktoren, Anti-Nukleäre-Antikörper (ANA), Antikörper gegen glatte Muskulatur (SMA), Anti-Phospholipid-Antikörper, Schilddrüsenautoantikörper. Antikörper gegen Ro und La sind bei der HCV-Infektion nicht nachweisbar. Da die Leberentzündung zumeist okkult verläuft, ist auch bei normalen Lebertransaminasen eine HCV-Infektion nicht ausgeschlossen und die Indikation zur HCV-Testung gegeben, wenn bestimmte serologische und klinische Hinweise vorliegen. Bei positivem HCV-Nachweis sollte auf hepatotoxische Medikamente verzichtet und die Möglichkeit einer viruseradizierenden Therapie mit α-Inferferon erwogen werden.

    Description / Table of Contents: Zusammenfassung An 42 Kniegelenkspunktaten verschiedenster rheumatischer Erkrankungen wurden enzymcytochemisch die saure Phosphatase, Beta-Glukuronidase, Alpha-Naphthylacetatesterase, Peroxydase und PAS-Reaktion in den Zellen der Synovia bestimmt und nach einem semiquantitativen Verfahren ausgewertet. Bei arthritischen Gelenkergüssen war der Aktivitätsindex der sauren Phosphatase und Beta-Glukuronidase in den Lymphozyten erhöht. Dieser Befund wird im Hinblick auf eine mögliche in vivo Stimulation bzw. Transformation der Lymphozyten diskutiert. In den Monozyten fiel bei Arthritiden eine Erhöhung des Aktivitätsindex der Alpha-Naphthylacetatesterase und Erniedrigung der Beta-Glukuronidase auf.
    Notes: Summary Acid phosphatase, ß-glucuronidase, alpha-naphthylacetatesterase, peroxidase and PAS-reaction were investigated by cytochemical enzyme reactions in synovial fluid cells of 42 samples from knee joints with various rheumatic diseases. These were calculated by a semi-quantitative method. The activity index of acid phosphatase and ß-glucuronidase was increased in lymphocytes of inflammatory synovial fluids. This finding is discussed in view of a possible in vivo stimulation or transformation of the lymphocytes. Concerning the monocytes there was an increase of the activity index of alpha-naphthylacetatesterase and a decrease of ß-glucuronidase in arthritic joint diseases.

    Notes: Summary Of 88 selected patients with possible ankylosing spondylitis (AS) 54 (61%) participated in two phases of a 10 years' follow-up study. Thirty-two (59%) developed definite AS according to the New York criteria, 10 (19%) had possible/undifferentiated seronegative spondylarthropathy (SSA) and 12 patients had other diagnoses. Only 3 (9%) of 35 patients with sacroiliitis did not fulfill the New York criteria for definite AS until the last examination. Sacroiliitis and radiological spinal signs of AS appeared rather late above a mean age of 40 years and after a mean disease duration of more than 10 years. After 18 years mean disease duration 25 (78%) of 32 AS patients had good or sufficient functional capacity indicating an overall good functional prognosis. HLA B27 typing proved to be useful in patients with possible early AS: 29 (71%) of 41 B27 positive and 3 (23%) of 13 B27 negative patients developed definite AS (p〈0.005). A combination of the B27 test with data of the history, clinical, laboratory, and radiological examination proposed as early diagnostic criteria detected patients with the outcome diagnosis of definite AS with even higher significance (p〈0.001). These criteria were also useful in the identification of patients with possible or undifferentiated SSA. The recently recognized entity of undifferentiated SSA should only be diagnosed after long term follow-up.
