Testing for anti-CCP antibodies discriminates HHC arthropathy from rheumatoid arthritis, as these patients were consistently anti-CCP negative. Thus, HHC arthropathy should be considered in the differential diagnosis of CCP-negative arthritis.
Macrophage inflammatory protein-1alpha (MIP-1alpha) is an interesting chemokine because in addition to its variety proinflammatory activities including chemotaxis and immunomodulation, it is a potent inhibitor of hematopoetic stem cell proliferation. Inhibition of erythroid progenitor cells due to MIP-1alpha or other cytokines can play a role in the pathogenesis of anemia which is one of the most common extra-articular features of active rheumatoid arthritis (RA). In 84 patients with RA, serological and immunological parameters were assessed to detect inflammatory mechanisms and anemia in relation to the serum concentrations of MIP-1alpha. All patients fulfilled the ACR criteria for the diagnosis of a definite or classic RA. We used a quantitative enzyme immuno assay for the detection of MIP-1alpha as well as for the measurement of the acute phase protein serum amyloid A (SAA), the erythropoiesis inducer erythropoietin (EPO) and the transferrin receptor (TfR). The immune activation marker neopterin was measured radioimmunologically. Half of the patients with RA were anemic with hemoglobin values below 12 g/dl. MIP-1alpha was found to be elevated significantly in serum of patients with active rheumatoid arthritis and in patients with anemia. Most of the anemic patients with markedly elevated acute phase reactions had an anemia with chronic diseases and not a functional iron deficiency alone. TfR correlated with EPO. The results show that enhanced expression of MIP-1alpha is indicative of systemic inflammation in RA. Moreover, besides the regulation of inflammatory processes, this chemokine may influence the pathogenesis of anemia in RA patients.
Inflammatory rheumatic diseases show an increased cardiovascular mortality. The reasons for this are unclear. Possible associations between atherosclerosis and autoimmune diseases like rheumatoid arthritis and systemic lupus erythematosus can be illustrated.
Zusammenfassung. Es erweist sich häufig als äuûerst schwierig, evidenzbasierte Daten mittels randomisierter doppelblinder, plazebokontrollierter, prospektiver Studien über komplexe Rehabilitationsprogramme zu erhalten. Aus diesem Grund wurde versucht, den Erfolg einer stationären Rehabilitation von Patienten mit Rheumatoider Arthritis (RA) mittels einer prospektiven Beobachtungsstudie zu dokumentieren. Die Untersuchungen fanden an 104 Patienten mit RA während einer 4-wöchigen Behandlung statt. Dabei wurden Daten über klinische, funktionelle und laborchemische Parameter erhoben. Ergebnisse: Es zeigte sich eine statistisch signifikante Abnahme der Anzahl geschwollener und druckdolenter Gelenke sowie der Morgensteifigkeit und der subjektiven Schmerzintensität bei gleichzeitigem Rückgang der Entzündungsparameter. Die Griffstärke verbesserte sich ebenso signifikant wie der funktionelle Status. Schlussfolgerung: Die stationäre Rehabilitation mittels komplexer therapeutischer Programme führt zu einer signifikanten Verbesserung der Lebensqualität von Patienten mit Rheumatoider Arthritis.Inpatient Rehabilitation in Rheumatoid Arthritis: Assessment of Therapeutic Success. In multidisciplinary rehabilitation programmes it can sometimes be difficult to achieve evidence-based data by means of randomized double-blind, placebo-controlled, prospective studies. Therefore, in patients with rheumatoid arthritis (RA), we tried to evaluate in a prospective observational study the influence of an inpatient rehabilitation stay. For this purpose, 104 patients with RA were included. During a four-weeks inpatient treatment investigations of clinical and functional parameters as well as laboratory measurements were carried out. Results: We could document a significant decrease in the number of swollen and painful joints, a reduced morning stiffness and subjective pain intensity together with a parallel decrease of the acute phase reactions. Grip strength and function improved simultaneously. Conclusion: Our results indicate that an extensive therapeutic rehabilitation programme can significantly improve the quality of life in patients with rheumatoid arthritis. VorbemerkungJedwedes therapeutische Verfahren muss objektiv und anhand möglichst gesicherter Daten auf seine Validität untersucht werden. Dies gilt nicht nur für neu einzuführende Therapeutika, sondern auch für oft längst etablierte, aber nicht durch evidenzbasierte Fakten untermauerte Therapieverfahren. In der Hierarchie einer evidenzbasierten Medizin steht die randomisierte, doppelblinde, plazebokontrollierte Studie an oberster Stelle. Dies gilt selbstverständlich auch für komplexe, krankheitsspezifische Therapiekonzepte. Auf stationäre Rehabilitationsverfahren (RV) ist jedoch ein doppelblindes Studiendesign aus offensichtlichen Gründen nicht anwendbar. Ebenso wenig ist eine Plazebokontrolle z. B. von physiotherapeutischen, heilgymnastischen, ergotherapeutischen etc. Maûnahmen möglich. Auch eine Randomisierung eines Patientenkollektivs in Patientengruppen mit oder ohne RV ist aus ...
