Radiographic progression in early rheumatoid arthritis: a 12-month randomized controlled study comparing the combination of cyclosporin and methotrexate with methotrexate alone.

OBJECTIVE: To determine whether patients with early rheumatoid arthritis (RA) treated with cyclosporin A (CsA) and methotrexate (MTX) in combination for 12 months show a lower rate of radiographic deterioration than those treated with MTX alone. METHODS: In this controlled and randomized single-blind trial, 61 consecutive patients with untreated RA of less than 2 yr duration were treated with either CsA + MTX combination therapy (n = 30) or MTX alone (n = 31). The primary end-point was radiographic progression after 12 months, measured using the damage score (DS) of the Sharp and van der Heijde method. RESULTS: Although there was a significant difference between the mean baseline and 12-month DS in both treatment groups (MTX/CsA, 1.93 +/- 0.90; MTX, 7.47 +/- 2.03), it was significantly less in the combination arm (P = 0.018). Of the 30 evaluable CsA + MTX patients, 16 (53%) were ACR20 responders, 15 (50%) ACR50 and 14 (47%) ACR70; the corresponding figures in the MTX arm were 19 (61%), 13 (44%) and 6 (19%). Toxicity was acceptable in both groups. CONCLUSIONS: In patients with early RA, CsA + MTX combination therapy led to a significantly lower rate of 12-month radiographic progression, was effective on inflammatory articular symptoms, and was well tolerated.

Incomplete lupus erythematosus: results of a multicentre study under the supervision of the EULAR Standing Committee on International Clinical Studies Including Therapeutic Trials (ESCISIT).

OBJECTIVE: Patients characterized with antinuclear antibodies (ANA) and disease symptoms related to one organ system can be described as having incomplete systemic lupus erythematosus (SLE). The aim of this multicentre study was to describe the outcome of these so-called incomplete SLE patients. Two aspects of the outcome were studied: (i) the disease course, defined by the presence or absence of clinical symptoms; and (ii) the number of patients that eventually developed full SLE. METHODS: Outcome parameters were the ACR criteria, the SLE disease Activity Index (SLEDAI), the European Consensus Lupus Activity Measure (ECLAM) and the requirement for treatment. In 10 European rheumatology centres, patients who had been evaluated in the last 3 months of 1994 and had been diagnosed as having incomplete SLE on clinical grounds for at least 1 yr were included in the study. All 122 patients who were included in the study were evaluated annually during 3 yr of follow-up. RESULTS: Our results are confined to a patient cohort defined by disease duration of at least 1 yr, being under clinical care at the different centres in Europe. These patients showed disease activity that was related mostly to symptoms of the skin and the musculoskeletal system, and leucocytopenia. During the follow-up, low doses of prednisolone were still being prescribed in 43% of the patients. On recruitment to the study, 22 of the 122 incomplete SLE patients already fulfilled the ACR criteria for the diagnosis of SLE. In the 3 yr of follow-up only three patients developed SLE. CONCLUSIONS: A high proportion of patients in our cohort defined on clinical grounds as having incomplete SLE eventually showed disease activity defined by the SLEDAI as well as ECLAM. However, only three cases developed to SLE during the follow-up. This suggests that incomplete SLE forms a subgroup of SLE that has a good prognosis.

A comparison of cyclosporine, sulfasalazine, and symptomatic therapy in the treatment of psoriatic arthritis.

OBJECTIVE: To compare the efficacy and tolerability of cyclosporine (CSA) with that of symptomatic therapy (ST) alone and sulfasalazine (SSZ) in the treatment of psoriatic arthritis (PsA). METHODS: Twelve rheumatology centers recruited 99 patients with active PsA in a 24 week, prospective, randomized, open, controlled study. The patients were treated with CSA (3 mg/kg/day) or SSZ (2,000 mg/day) plus ST, or ST alone (nonsteroidal antiinflammatory drugs, analgesics, and/or prednisone < or = 5 mg/day). The primary endpoint was the 6 month change in pain. Analyses were on the basis of the intention-to-treat principle. RESULTS: In comparison with both SSZ and ST, there was a statistically significant difference in favor of CSA in terms of the mean changes in the pain score (p < 0.05), which was considered the primary response variable. A significant decrease in favor of CSA versus ST alone was also observed for swollen joint count (p = 0.05), tender joint count (p = 0.01), joint/pain tenderness score (p = 0.002), patient and physician global assessment by at least one point (p = 0.04 and 0.01, respectively), total Arthritis Impact Measurement Scale score (p = 0.002), and spondylitis functional index (p = 0.002). There was a statistically significant difference in the ACR 50% and ACR 70% response rates between the CSA and ST groups (p = 0.02, 0.05). Comparing the SSZ and ST alone groups, only the spondylitis functional index decreased significantly in the SSZ treated patients (p = 0.03). The Psoriasis Area and Severity Index was significantly lower in the CSA than in the ST and SSZ groups (p = 0.0001 and 0.01, respectively). Decrease in erythrocyte sedimentation rate was significant only in the SSZ versus the ST group (p = 0.02), whereas reduction in C-reactive protein was significant in the CSA treated patients compared with the ST group (p = 0.006). The most common adverse event in the CSA group was mild, reversible kidney dysfunction. CONCLUSION: The results of this open trial confirm that CSA is well tolerated by patients with PsA and suggest that it is more efficacious than ST or SSZ.

Joint symmetry in early and late rheumatoid and psoriatic arthritis: comparison with a mathematical model.

OBJECTIVE: To establish a mathematical model to predict the probability of symmetry of joint involvement as a function of the number of joints involved and to compare expected with actual probabilities in psoriatic arthritis (PsA) and rheumatoid arthritis (RA) and in early and late disease. METHODS: Random involvement of joints was assumed, and the binomial theorem was used to give the frequency distribution of involved joints as a function of each joint count. Ten joint pairs were included: shoulder, elbow, wrist, metacarpophalangeal joints, proximal interphalangeal (PIP) joints of the hands, hip, knee, ankle, metatarsophalangeal joints, and PIP joints of the feet. Observed probabilities were obtained from subjects with early (duration < or =12 months) and late PsA and RA. RESULTS: The number of subjects in each of the disease subgroups was as follows: early PsA n = 33, late PsA n = 77, early RA n = 61, late RA n = 93. Observed probabilities of symmetry exceeded predicted probabilities for all disease subgroups. The median number of involved joints in each group was as follows: early PsA 4, late PsA 8, early RA 8, late RA 15 (chi2 = 95.3, 3 degrees of freedom, P = 0.0001, by Kruskal-Wallis test). After correcting for the discrepancy in the number of involved joints, no difference in joint symmetry was found between the groups (chi2 = 1.77, P = 0.62 by Friedman two-way analysis of variance). Similar results were obtained when individual hand and foot joints were analyzed separately. CONCLUSION: The pattern of joint involvement is often used to distinguish between rheumatoid and psoriatic arthritis. This study confirms that symmetry is largely a function of the total number of joints involved and that, in terms of joint pattern, differences between these disorders are more quantitative than qualitative. Both disorders have high absolute values of symmetry, particularly in the joints of the wrist and hand.

Systemic lupus erythematosus: clinical features in patients with a disease duration of over 10 years, first evaluation.

OBJECTIVE: Most information available about the disease course of patients with systemic lupus erythematosus (SLE) is restricted to the first 5 yr after disease onset. Data about the disease course 10 yr after disease onset are rare. The aim of this multicentre study was to describe the outcome of SLE patients with a disease duration of >10 yr. METHODS: Outcome parameters were the SLE Disease Activity Index (SLEDAI), the European Consensus Lupus Activity Measure (ECLAM), the Systemic Lupus International Collaborative Clinics/American College of Rheumatology Damage Index (SLICC/ACR), a global damage index (DI) and required treatment. In 10 different European rheumatology centres, all SLE patients who were evaluated in the last 3 months of 1994, and who had been diagnosed with SLE at least 10 yr ago, were included in the study. RESULTS: It should be stressed that our results are confined to a patient cohort, defined by a disease duration of at least 10 yr, and who are still under clinical care at the different centres in Europe. These SLE patients still showed some disease activity, related to symptoms of the skin and musculoskeletal systems, next to the presence of renal involvement. A total of 72% of the patients needed treatment with prednisolone (</=7.5 mg). The cumulative damage was overall related to clinical features of the central nervous system (14%) and renal involvement (14%), next to deforming arthritis (14%), osteoporosis (15%) and hypertension (40%). The prevalences of obesity, Cushing appearance and diabetes are highly suggestive that the ongoing treatment and that in the past might have had an impact on the total sum of end-organ damage. CONCLUSIONS: After 10 yr, a high proportion of patients in our cohort continued to show evidence of active disease, defined by the SLEDAI as well as ECLAM. The DI was related to the involvement of the central nervous system, renal involvement and the presence of hypertension.

Psoriatic arthritis in British and Italian patients: a comparative clinical, radiologic, and scintigraphic study.

OBJECTIVE: To investigate the similarities and differences in pattern and severity of clinical expression of psoriatic arthritis (PsA) in British and Italian patients. METHODS: Detailed clinical data were obtained on 48 British patients with PsA and compared with the data of 48 Italian patients. A systematic evaluation of joints, spine, and skin was performed. Forty-one British and 42 Italian patients also underwent a whole body bone scintigram. Radiographic details of hands and wrists were also taken. RESULTS: The Italian patients did not differ from their British counterparts with respect to duration of arthritis, sex, clinical subgroups, axial involvement, number of tender and swollen joints, or radiographic score. However, significant differences were found with respect to age, duration of psoriasis, number of joints with deformity and/or loss of function, number of affected joints, and number of "active" joints on scintigraphy, which were all higher in the British group. After correction for age, duration of arthritis, and duration of psoriasis the only significant difference was the number of affected joints. CONCLUSION: Our findings suggest that British patients with PsA are more severely affected than a matched cohort of Italian patients.

Pharmacokinetic effects of conversion to a new formulation of cyclosporin A in rheumatoid arthritis patients.

In this study we aimed at evaluating the modifications in the pharmacokinetic profile of cyclosporin A (CyA) after conversion from standard formulation (CyA-ST) to a new formulation (CyA-NF, Sandimmun Neoral) in patients with rheumatoid arthritis (RA). It was an open, crossover study that involved 15 RA patients who were on stabilized treatment with CyA-ST. The patient continued receiving CyA-ST (mean dose of 3.0 +/- 0.7 mg/kg per day) for 3 weeks and then converted 1:1 to CyA-NF for a further 3 weeks. CyA pharmacokinetics were established on day 1 (CyA-ST evaluation) and +21 (CyA-NF evaluation). The results showed that the bioavailability of CyA-NF was greater than that of CyA-ST (AUC tau, bss: 3335 +/- 1300 vs 2667 +/- 1155 ng.h/ml, P = 0.0073; AUC tau, bss ratio 1.26 +/- 0.40 vs 1.0 as reference, P < 0.05), with higher and earlier peak blood concentrations (Cmax: 677 +/- 256 vs 475 +/- 213 ng/ml, P = 0.0329; tmax: 1.5 +/- 0.7 vs 2.6 +/- 1.6 h, P = 0.0720). The pharmacokinetic profile of CyA-NF showed greater between-patient reproducibility (lower CV% for all of the considered parameters). In conclusion, when using CyA-NF instead of CyA-ST, greater and more constant exposure to CyA should be expected.

Cyclosporin A in the treatment of adult onset Still's disease.

OBJECTIVE: To determine whether cyclosporin A (CyA) is a useful option in the treatment of adult onset Still's disease (ASD). METHODS: Low dose CyA was given to 6 patients with chronic or relapsing ASD who had not been prescribed any other second line agents during the previous 6 mo. RESULTS: The disease completely remitted in 4 patients and improved markedly in the remaining 2. The corticosteroid requirement was substantially reduced in all cases. Tolerability was rated good or very good by all patients but one, who reported good tolerance to CyA only in a new formulation. CONCLUSION: CyA may be included among the second line agents used in the treatment of refractory ASD.

Cutaneous lymphocyte antigen-positive T lymphocytes preferentially migrate to the skin but not to the joint in psoriatic arthritis.

OBJECTIVE: To investigate whether T cell migration into different sites of inflammation (skin and synovium) within the same individual is principally regulated by tissue-specific homing or by more general mechanisms related to inflammation. METHODS: Expression of cutaneous lymphocyte antigen (CLA) and its ligand, E-selectin, was analyzed by immunohistochemistry and immunofluorescence using paired skin and synovial membrane (SM) samples from patients with psoriatic arthritis (PsA). To investigate disease specificity, delayed-type hypersensitivity (DTH) skin lesions, induced by tuberculin purified protein derivative, and SM from patients with rheumatoid arthritis (RA), were studied as controls. To directly examine cell migration in in vivo, the proportion of CLA+ T lymphocytes migrating into suction-induced skin blisters was assessed by flow cytometry. Using the same technique, levels of paired peripheral blood and synovial fluid (SF) T cells were also analyzed. RESULTS: CLA+ T cells preferentially accumulated in the skin, but not in the joint, of patients with PsA. Similarly, CLA+ T lymphocytes predominated in the DTH skin lesions of RA patients, but were very rare in the SM of RA patients, and were scarcely represented in the SF of patients with several chronic inflammatory arthropathies. In addition, CLA+ T lymphocytes preferentially migrated into epidermal skin blisters. This preferential pattern of CLA+ T cell accumulation was not related to the selective expression of E-selectin, since this was similar in the skin and SM of both PsA and RA patients. CONCLUSION: The distinct pattern of T cell infiltration into sites of inflammation within the skin and synovium is regulated by both organ-specific homing and general inflammation-related mechanisms.

Rifamycin SV versus triamcinolone in local treatment of rheumatoid synovitis.

This study was aimed to evaluate the usefulness of rifamycin SV as an agent for local treatment of rheumatoid synovitis. Rifamycin SV was compared with triamcinolone acetonide in a randomized controlled trial on 87 patients with rheumatoid arthritis and with persistent knee synovitis. The treatment with rifamycin consisted of several weekly intra-articular injections, whereas triamcinolone was given as a single intra-articular injection. At the end of the therapy, 27 (61.4%) of the 44 rifamycin patients and 39 (91%) of the 43 steroid patients responded well to the treatment, and this difference was significant (p < 0.01). Rifamycin SV was responsible for unpleasant local side effects in all cases. In both groups, after 1 year of follow-up the synovitis had relapsed in about 42% of cases. We conclude that rifamycin SV is less useful than triamcinolone acetonide in the local treatment of rheumatoid synovitis.

A re-evaluation of the osteoarticular manifestations of psoriasis.

A distinctive peripheral arthropathy associated with psoriasis is well recognized, the classical pattern describing an asymmetrical oligoarthritis with predominant distal interphalangeal joint (DIP) involvement. There is some dispute about the frequency of this classical pattern and of the pattern of symmetrical polyarthritis resembling rheumatoid arthritis. Some of the dispute may be a result of loose definitions. In this clinical and scintigraphic study of 50 patients with psoriatic arthritis we have used tighter definitions of disease pattern and have found that 68% of this group had a symmetrical polyarthritis similar to that found in rheumatoid arthritis. Yet, arthritis associated with psoriasis differs from rheumatoid arthritis in a number of ways including the pattern of joint involvement, extra-articular osseous features, and radiological changes. Scintigraphic changes in psoriatic arthritis suggest that subclinical involvement of the manubriosternal and sternoclavicular joints is common, suggesting an association between psoriasis vulgaris and arthro-osteitis. A modified classification of the osteoarticular manifestations of psoriasis is proposed.

Immunoglobulin heavy chain gene polymorphisms in Italian patients with psoriasis and psoriatic arthritis.

A polymorphism of the switch region of the mu IgH gene (S mu) is associated with arthritis in English patients with psoriasis. In this study, Italian patients with psoriasis alone (PS) or psoriatic arthritis (PSA) were analysed by Southern blot using DNA probes for the S mu region and a hypervariable locus 5' of the joining (JH) region of IgH (5' JH). No association between PSA and IgH gene polymorphisms was found. However, an association was found between PS and a genotype of the 5' JH region (Fisher's P = 0.0002, RR = 27). Additional DNA markers around the S mu region may reveal more accurate markers for PS or PSA.

Cytidine deaminase activity, C reactive protein, histidine, and erythrocyte sedimentation rate as measures of disease activity in psoriatic arthritis.

Cytidine deaminase activity, C reactive protein, histidine, and erythrocyte sedimentation rate were measured in 36 subjects with psoriatic arthritis of varying disease duration and severity. Although cytidine deaminase activity may provide an integrated measure of synovial inflammation in rheumatoid arthritis, neutrophil accumulation in psoriatic plaques compromises this measure in psoriatic arthritis. Low histidine concentrations confirm that this amino acid provides a non-specific index of synovial inflammation. In psoriatic arthritis high C reactive protein concentrations seem to be associated with extensive joint destruction. In this study the erythrocyte sedimentation rate was found to be the best laboratory guide to clinical disease activity in psoriatic arthritis.

[Clinical framework of psoriatic arthropathy. Proposal of an evaluation protocol].

Psoriatic arthropathy is an inflammatory seronegative arthritis characterized by an involvement of peripheral or axial joints in association with psoriasis. In this study the clinical features of both skin and joints have been observed simultaneously by a rheumatologist and a dermatologist. We have finally proposed a clinical protocol based on PASI to evaluate psoriasis and on a simple subset classification to estimate joint involvement.
