    Notes: Abstract: Objective: To investigate the effects of clodronate on clinical disease activity, inflammatory alterations and cartilage destruction, periarticular and axial bone volume and bone turnover in chronic antigen-induced arthritis (AIA; day 28).¶Methods: Rats with AIA were treated with clodronate (5 mg/kg/day continuously; 20 mg/kg/day intermittently or high-dose with 300 mg/kg 3 hours after arthritis induction +20 mg/kg/day continuously, respectively). Joint pathology was examined by histology. Bone volume and cellular turnover parameters of the right tibia head and the third lumbar vertebra were evaluated by histomorphometry. The findings were compared with those of healthy controls, sham-treated AIA and AIA treated continuously with 250 μg/kg of dexamethasone.¶Results: All three therapy regimens with clodronate resulted in a significant reduction of joint swelling, histopathological inflammatory changes and cartilage destruction in comparison with sham-treated AIA. The antiinflammatory effect of high-dose clodronate was comparable with dexamethasone. The intermittent administration of 20 mg/kg/day of clodronate completely prevented periarticular bone loss by reduction of bone resorption without affecting bone formation at the periarticular and axial bone. Both continuous treatment with 5 mg/kg/day of clodronate and high-dose clodronate therapy partially prevented periarticular bone loss and reduced parameters of bone formation at the axial bone to values below those of healthy controls.¶Conclusion: High-dose clodronate therapy exerts an excellent preventive effect on clinical disease activity and on joint destruction in AIA. However, continuous treatment with high doses of clodronate may result in a low turnover state of bone remodelling.¶

    Description / Table of Contents: Summary Active vitamin D metabolites are not only involved in the regulation of bone metabolism but exerts immunomodulatory effects important in the regulation of inflammatory processes. The purpose of the present study was to evaluate the effects of a short-time treatment with 1α-hydroxycholecalciferol on both disease activity and bone metabolism in patients with rheumatoid arthritis (RA). The effects of an adjuvant therapy with 1μg 1α-hydroxycholecalciferol over eight weeks on conventional parameters of disease activity (Ritchie index, duration of morning stiffness, C-reactive protein, ESR), serum levels of cytokins and soluble cytokine receptors (TNF-α, IL-6, ¶IL-4, sIL-2R, sIL-6R) and parameters of bone metabolism (bone-specific alkaline phosphatase, osteocalcin, renal excretion of pyridinolin- and desoxypyridinolin-collagen-crosslinks, serum levels of parathormon, 1,25-dihydroxycholecalciferol and calcium, daily urinary calcium excretion) were investigated in 20 patients with RA. The treatment with 1α-hydroxycholecalciferol resulted in an insignificant decrease in the number of swollen and tender joints, morning stiffness, CRP and ESR. Furthermore, a non-significant decrease in serum levels of TNF-α and IL-6 and an increase in IL-4 was observed. The treatment led to a significant decrease of bone-specific alkaline phosphatase (p=0.001), osteocalcin (p=0.04) and renal excretion of pyridinolin-crosslinks (p=0.022) and to an increase of both serum calcium (p=0.01) and daily urinary calcium excretion (p=0.004). The results of this pilot study in a small group of RA patients indicate that an adjuvant therapy with active vitamin D metabolites may not only have preventive effects on systemic bone loss but also may inhibit the inflammatory and destructive process in RA in a limited degree.
    Notes: Zusammenfassung Aktive Vitamin D-Metabolite sind nicht nur entscheidend am Knochenmetabolismus beteiligt, sondern erfüllen darüber hinaus wichtige immunmodulatorische Funktionen im Rahmen von entzündlichen Prozessen. Ziel unserer Studie war es, den Effekt einer Kurzzeittherapie mit 1α-Hydroxycholecalciferol auf entzündliche Aktivität und Knochenmetabolismus bei Patienten mit rheumatoider Arthritis (RA) zu evaluieren. Bei 20 Patienten mit RA wurde der Einfluß einer additiven Therapie mit 1μg 1α-Hydroxycholecalciferol über 8 Wochen auf klinische und paraklinische Parameter der entzündlichen Aktivität (Ritchie-Index, Dauer der Morgensteife, CRP, BSG), die Serumspiegel der Zytokine TNF-α, IL-6, IL-4 sowie der löslichen Zytokinrezeptoren sIL-2R und sIL-6R und auf Parameter des Knochenmetabolismus (Knochenisoenzym der alkalischen Phosphatase, Osteocalcin, renale Elimination von Pyridinolin- und Desoxypyridinolin-Kollagen-Crosslinks, Serumspiegel von Parathormon, 1,25-Dihydroxycholecalciferol und Kalzium, Kalziumausscheidung im 24-Stundenharn) untersucht. Die Therapie mit 1-α-Hydroxycholecalciferol führte zu einer gleichsinnigen, wenn auch nicht signifikanten Abnahme der Anzahl druckschmerzhafter und geschwollener Gelenke, der Morgensteife sowie von CRP und BSG. Für die Serumspiegel von TNF-α und IL-6 war eine tendentielle Abnahme, für IL-4 eine tendentielle Zunahme zu beobachten. Hinsichtlich des Knochenmetabolismus war eine signifikante Abnahme des Knochenisoenzyms der alkalischen Phosphatase (p=0,001), von Osteocalcin (p=0,04) sowie der renalen Exkretion von Pyridinolin-Crosslinks (p=0,022) bei gleichzeitigem Anstieg von Serumkalzium (p=0,01) und Kalziumausscheidung im 24-Stundenharn (p=0,004) zu verzeichnen. Die Ergebnisse der Pilotstudie in einem kleinen Kollektiv von RA-Patienten weisen darauf hin, daß eine adjuvante Therapie mit aktiven Vitamin D-Metaboliten nicht nur der Entwicklung einer systemischen Osteoporose entgegenwirken, sondern zusätzlich den entzündlichen Prozeß und evtl. auch die destruktiven Vorgänge in einem limitierten Umfang hemmen könnte.

    Notes: Abstract. In several studies on patients with rheumatoid arthritis, an association of bone loss with a persistently high disease activity has been found. The aim of our study was to investigate the relation between disease activity and serum levels of vitamin D metabolites, parathyroid hormone (PTH), and parameters of bone turnover in patients with rheumatoid arthritis. A total of 96 patients (83 women and 13 men) were divided into three groups according to disease activity measured by serum levels of C-reactive protein (CRP). In the whole group, serum levels of 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) (P 〈 0.001) and PTH (P 〈 0.05) were negatively correlated to disease activity. The urinary excretion of collagen crosslinks—pyridinoline (Pyd) (P 〈 0.001) and deoxypyridinoline (Dpd) (P 〈 0.05)—showed a positive correlation with disease activity. The inverse correlation between serum 1,25(OH)2D3 and disease activity was separately evident in patients with (P 〈 0.001) and without (P 〈 0.01) glucocorticoid treatment, in pre- (P 〈 0.01) and postmenopausal (P 〈 0.001) women, and in men (P 〈 0.01). 1,25(OH)2D3 and PTH serum levels were positively correlated to serum bone alkaline phosphatase (ALP) (P 〈 0.01). The results indicate that high disease activity in patients with rheumatoid arthritis is associated with an alteration in vitamin D metabolism and increased bone resorption. The decrease of 1,25(OH)2D3 levels in these patients may contribute to a negative calcium balance and inhibition of bone formation. Furthermore, low levels of 1,25(OH)2D3 as an endogenous immunomodulator suppressing activated T cells and the proliferation of cells may accelerate the arthritic process in rheumatoid arthritis.

    Description / Table of Contents: Summary Clinically the nail organ ist easy to investigate. When estimating dermato-rheumatological diseases, knowledge of important associated nail symptoms is extremely helpful. In some diseases like osteoarthropathia psoriatica and special variants, Reiter’s syndrome and connective tissue disease, typical or even characteristic symptoms can be found. In other disorders like rheumatoid arthritits, goal and systemic vasculitis, associated nail disorders are not uncommon, but of less diagnostic specificity. We review data from the literature and from our dermato-rheumatological outpatient clinic.
    Notes: Zusammenfassung Das Nagelorgan ist der klinischen Untersuchung leicht zugänglich. Im Rahmen dermatologisch-rheumatologischer Krankheitsbilder ist die Kenntnis der wichtigsten assozierten Nagelveränderungen sehr hilfreich. Für einige wichtige Erkrankungen wie der psoriatrische Osteoarthropathie einschließlich der Sonderformen, dem Morbus Reiter und den Kollagenosen finden sich typische, teils auch charakteristische Symptome. Für andere Erkrankungen wie die Rheumatoidarthritis, die Arthritis urica und die Systemvaskulitiden sind assoziierte Nagelerkrankungen nicht selten, aber von geringerer diagnostischer Spezifität. Die vorliegende Übersicht bespricht sowohl Literatur – als auch eigene, in einer dermatologisch-rheumatologischen Gemeinschaftssprechstunde erhobene Daten.

    Notes: Abstract Many patients with systemic lupus erythematosus (SLE) receive long-term treatment with azathioprine and prednisolone to control disease activity. In a retrospective study we evaluated the efficacy of combined treatment with azathioprine (2 mg/kg body weight/d) and low-dose prednisolone (7–12 mg/d) and the predictors of disease flares during this therapy regimen in 61 patients with SLE. We found three predictors of flares: renal disease, persistence of dsDNA antibodies for at least 1 year after the beginning of treatment and reduction in azathioprine dosage to below 2 mg/kg/d. The occurrence of flares was significantly associated with a higher rate of disease-related death. Furthermore, the persistence of dsDNA antibodies for at least 2 years was associated with progression of renal disease. We concluded that suppression of production of dsDNA antibodies with high avidity is a suitable parameter to determine efficacy of treatment and long-term outcome during combined therapy with azathioprine and low-dose prednisolone in SLE.
