A prospective study was carried out to determine the usefulness of 99TCm-human immunoglobulin G (HIG) scintigraphy in the assessment of the severity of joint inflammation. Twenty-four patients with rheumatoid arthritis were studied. The presence or absence of pain and/or swelling was evaluated in 34 joints and a clinical index taking into account the surface area of each joint was calculated. We measured the following biological markers of inflammation activity: erythrocyte sedimentation rate, C-reactive protein, haemoglobin, platelet count, serum levels of IL-6, TNF-alpha and soluble receptors of IL-2. Scintigraphic was performed 4 h after the injection of 740 MBq 99Tcm-HIG. The scans were evaluated by visual and quantitative analysis and the scores in each joint were weighted for joint size. Pathological uptake of the radiopharmaceutical was noted in 46% (24/52) of joints evaluated as painful, 89% (146/164) of swollen joints and 94% (78/83) of both painful and swollen joints. Both the visual and the quantitative scintigraphic indices correlated significantly with the clinical index, the number of painful joints, the number of swollen joints and several biological markers of inflammation. A very high correlation was also found between the visual and the quantitative scintigraphic indices (r = 0.91, P < 0.0001). In conclusion, 99Tcm-HIG scintigraphy is an objective test to detect synovitis and to assess the severity of inflammation. A careful visual analysis of scans is good enough for routine evaluations and computer quantitative analysis should be used when more accurate intra-individual variation is required.

Type 1 cytokines (a.o. IL-2 and IFN-gamma) play an important role in the pathogenesis of rheumatoid arthritis. On the other hand, IgE-mediated diseases such as allergic asthma and atopic dermatitis show a type 2 cytokine (amongst others IL-4 and IL-5) profile. This study examined simultaneously the intracellular production of IL-2, IFN-gamma, IL-4 and IL-5 in T-lymphocytes of patients with rheumatoid arthritis during treatment with methotrexate or salazopyrin, patients with allergic asthma or atopic dermatitis under stable treatment, compared to healthy controls.A three-colour flow cytometric analysis was used for cytokine detection in T-helper cells and T-suppressor/cytotoxic cells. Compared to controls, patients with symptomatic atopic dermatitis showed an increased number of IL-4-producing T-helper lymphocytes in basal circumstances (P=0.001), in contrast to asymptomatic allergic asthma patients. Compared to controls, rheumatoid arthritis patients, treated with salazopyrin, showed an increased number of IL-2-producing T-helper and T-suppressor/cytotoxic lymphocytes after in vitro stimulation with PMA and ionomycin (P=0.01). In contrast, rheumatoid arthritis patients, treated with methotrexate, a more potent disease modifying drug, did not show this type 1 cytokine profile. A positive correlation was found between the number of IFN-gamma producing T-helper cells and disease activity (Ritchie Index and number of swollen joints) in both rheumatoid arthritis patient groups. Active atopic dermatitis patients showed a type 2 cytokine profile, whereas stable asthma patients with lower disease activity did not show a predominance of type 2 cytokines. Rheumatoid arthritis patients under treatment with salazopyrin had a type 1 cytokine profile, which could not be demonstrated in patients treated with methotrexate. This imbalance between type 1 and type 2 cytokines in different immune mediated disorders can be related with treatment and the grade of disease activity. These results stress the need for further investigation of the influence of therapy on cytokine profiles.

Our objective was to evaluate the levels of interleukin-6 (IL-6), soluble receptors of IL-2 (sIL-2R), IL-10, and IL-1 receptor antagonists (IL-1ra) in the serum of patients with psoriatic arthritis (PsA) and to assess the correlation between these levels and parameters of clinical activity of skin and joint disease. In total, 34 patients with PsA and ten healthy volunteers participated in the study. Assessment of joint disease included duration of morning stiffness, number of tender and swollen joints, right and left grip, the presence of inflammatory spinal back pain, and Schober test. Current severity of skin disease was graded according to the psoriasis area and severity index (PASI). Erythrocyte sedimentation rate (ESR) was determined as a marker of disease activity. Serum levels of IL-6, sIL-2R, IL-1ra, and IL-10 were measured by an enzyme immunoassay kit. Significantly higher serum levels of IL-6, sIL-2R, IL-1ra, and IL-10 were found in patients with PsA in comparison with healthy volunteers. A statistically significant correlation was found between levels of sIL-2R and PASI, whereas no association was found with clinical parameters of joint severity. Levels of IL-lra correlated with the number of tender and swollen joints. No correlation was found between levels of IL-6, IL-10, and clinical parameters of skin and joint severity. In the group of patients with PsA, serum levels of sIL-2R clearly correlated with severity of skin disease, whereas levels of IL-1ra were associated with joint severity.
