Background: Balneotherapy has been successfully used to treat various rheumatic diseases, but has only recently been evaluated for the treatment of fibromyalgia. Since no effective treatment exists for this common rheumatic disease, comple­mentary methods of treatment have been attempted.

Objectives:To assess the effectiveness of batneotherapy at the Dead Sea area in the treatment of patients suffering from both fibromyalgia and psoriatic arthritis.

Methods: Twenty-eight patients with psoriatic arthritis and fibromyalgia were treated with various modalities of bat­neotherapy at the Dead Sea area. Clinical indices assessed were duration of morning stiffness, number of active joints, a point count of 18 fibrositic tender points, and determination of the threshold of tenderness in nine fibrositic and in four control points using a dolorimeter.

Results: The number of active joints was reduced from 18.4+10.9 to 9+8.2 (P< 0.001). The number of tender points was reduced from 12.6+2 to 7.1±5 in men (P<0.003) and from 13.1+2 to 7.5+3.7 in women (P<0.001). A significant improvement was found in dolorimetric threshold readings after the treatment period in women (P< 0.001). No correlation was observed between the reduction in the number of active joints and the reduction in the number of tender points in the same patients (r= 0.2).

Conclusions: Balneotherapy at the Dead Sea area appears to produce a statistically significant substantial improvement in the number of active joints and tender points in both male and female patients with fibromyalgia and psoriatic arthritis. Further research is needed to elucidate the distinction between the benefits of staying at the Dead Sea area without balneotherapy and the effects of balneotherapy in the study population.

Objectives: To help clinicians and laboratory scientists recognize and utilize vasculitis-related ANCAs as an aid in diagnostic workup and patient follow-up, and be aware that ANCAs with different characteristics are commonly found in other chronic inflammatory conditions that persistently engage neutrophils in the inflammatory process.

Methods: Indirect immunofluorescence and enzyme immunoassay methods were used to detect ANCAs with both known and unknown neutrophil autoantigenic targets.

Results: Primary necrotizing small vessel vasculitides such as Wegener’s granulomatosis, Churg-Strauss syndrome, microscopic polyangiitis, and renal-limited rapidly progressive necrotizing glomerulonephritis target either the serine protease proteinase 3 or myeloperoxidase  in azurophilic granules. In ulcerative colitis and rheumatoid arthritis, we found multiple ANCA targets contained in azurophilic and specific granules, the cytosol and the nucleus, whereas PR3² and MPO³ were not, or only weakly, recognized.

Conclusions: ANCAs typically found in active SVV⁴ are demonstrable both by indirect immunofluorescence and antigen-specific enzyme immunoassay, and strong reactivity to either PR3 or MPO is characteristic. Strong ANCA with MPO reactivity is also found in some patients with drug-induced syndromes (lupus, vasculitis). Intermediate to strong perinuclear ANCAs are found in a substantial proportion of patients with UC⁵ (40–60%) and RA⁶ (30–70%), but in these conditions the ANCAs have many antigen targets that are only weakly recognized.
