Abstract
The introduction of biologic DMARDs into rheumatology has resulted in a substantial reduction of the burden of many rheumatic diseases. In the slipstream of the success achieved with these biologic DMARDs, some conventional immunosuppressive drugs have also found use in new indications. Notably, mycophenolate mofetil, azathioprine and tacrolimus have made their way from solid organ transplantation drugs to become useful assets in rheumatology practice. Mycophenolate mofetil and azathioprine inhibit the purine pathway and subsequently diminish cell proliferation. Both drugs have a pivotal role in the treatment of various rheumatic diseases, including lupus nephritis. Tacrolimus inhibits lymphocyte activation by inhibiting the calcineurin pathway. Mycophenolate mofetil and tacrolimus are, among other indications, increasingly being recognized as useful drugs in the treatment of interstitial lung disease in systemic rheumatic diseases and skin fibrosis in systemic sclerosis. A broad array of trials with mycophenolate mofetil, azathioprine and/or tacrolimus are ongoing within the field of rheumatology that might provide further novel avenues for the use of these drugs. In this Review, we discuss the historical perspective, pharmacodynamics, clinical indications and novel avenues for mycophenolate mofetil, azathioprine and tacrolimus in rheumatology.

Abstract
Generalized pustular psoriasis (GPP) is a rare disease characterized by recurrent fever and systemic flushing accompanied by extensive sterile pustules. The committee of the guidelines was founded as a collaborative project between the Japanese Dermatological Association and the Study Group for Rare Intractable Skin Diseases under the Ministry of Health, Labour, and Welfare Research Project on Overcoming Intractable Diseases. The aim of the guidelines was to provide current information to aid in the treatment of patients with GPP in Japan. Its contents include the diagnostic and severity classification criteria for GPP, its pathogenesis, and recommendations for the treatment of GPP. Since there are few clinical trial data with high levels of evidence for this rare disease, recommendations by the committee are described in the present guidelines.

Abstract
BACKGROUND Psoriatic arthritis is an inflammatory arthritis the primary manifestations of which are locomotor and skin disease. Although a number of guidelines have been published citing strategies for reducing disease progression, the evidence base for disease-modifying agents is unclear. This forms the focus of this systematic review. METHODS The systematic review was undertaken according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2009 checklist. We selected randomized controlled trials (RCTs) that looked at the impact of interventions with disease-modifying agents, either synthetic drugs or biologics on musculoskeletal outcomes, notably American College of Rheumatology 20 percent responders. Results were analyzed using Review Manager 5.1.6 (Cochrane Collaboration, Oxford, UK). Whilst our primary focus was on published trials, we also looked at new trials presented in abstract form in 2013-2014 that were not yet published to avoid omitting important and up-to-date information on developing treatments. RESULTS Our in-depth analysis included 28 trials overall enrolling 5,177 patients published between the 1980s and now as well as limited analysis of some studies in abstract form as described earlier. The most frequently available locomotor outcome measure was the American College of Rheumatology 20 percent responders. The risk ratio for achieving an American College of Rheumatology 20 percent responders response was positive in favor of treatment (risk ratio 2.30; 95% confidence interval 1.78-2.96); however, there was evidence of considerable heterogeneity between trials. Overall randomized controlled trials of established synthetic disease-modifying agents were largely negative (methotrexate, ciclosporin and sulfasalazine) though leflunomide showed a small positive effect. A new synthetic agent, apremilast, did show a positive benefit. For biologics, TNF inhibitors already licensed for use were effective and similar benefits were seen with newer agents including ustekinumab, secukinumab, brodalumab, and abatacept, although the latter did not impact on skin problems. Important limitations of the systematic review included, first, the fact that for many agents there were little data and, second, much of the recent data for newer biologics were only available in abstract form. CONCLUSION Conventional disease-modifying agents, with the possible exception of leflunomide, do not show clear evidence of disease-modifying effects in psoriatic arthritis, though a newer synthetic disease-modifying agents, apremilast, appears more effective. Biologic agents appear more beneficial, although more evidence is required for newer agents. This review suggests that it may be necessary to review existing national and international management guidelines for psoriatic arthritis.

Abstract
Psoriatic arthritis (PsA) is a chronic inflammatory musculoskeletal disorder associated with a heterogeneous disease presentation, varied disease expression and an unpredictable but often chronically destructive clinical course. Joint damage can occur early in the disease; indeed, several imaging modalities have demonstrated subclinical joint involvement in psoriasis patients without musculoskeletal signs or symptoms. Efforts are underway to validate questionnaires that will enable dermatologists to screen patients with psoriasis for the presence of musculoskeletal disease. To date, the use of therapies in patients with early PsA has not been reported in randomized controlled trials. Moreover, conventional agents are partially effective in established PsA but, in general, trials with DMARDS have not included validated outcome measures for the different manifestations of PsA. Tumor necrosis factor antagonists can alleviate the signs and symptoms of established psoriatic arthritis and inhibit radiographic progression, but the therapeutic impact of early intervention with these agents requires further study. The extent of disease and the presence of comorbidities should be used to guide treatment decisions and to minimize adverse events.

Abstract
Psoriatic arthritis (PsA) is an inflammatory arthritis associated with psoriasis. The etiology of PsA is unknown; however, there is mounting evidence for a strong genetic contribution to PsA. A few disease-related genes have already been identified in PsA. Cytokines associated with PsA appear to be the most promising targets for pharmacogenetics. Blockade of TNF-α and IL-12/23 is associated with a marked clinical response to PsA and/or psoriasis, implying a pivotal role of these cytokines in the pathogenesis of these two disease entities. To date, only the -308 variant of the TNF-α promoter gene has been shown to be important in predicting response to TNF-α blockade in inflammatory arthritis.

Abstract
Despite the widespread use of methotrexate in the treatment of psoriatic arthritis (PsA), there are patients who are either refractory, develop toxicity to, or refuse to take methotrexate. In search of an alternative, we studied long-term tolerability of and clinical response to azathioprine (AZA) in PsA patients in comparison with matched controls and followed them in a longitudinal clinic. Twenty-eight of 485 patients followed prospectively between 1978 and 1998 took AZA during their clinic follow-ups. Eighteen of the 28 took AZA for 12 months and were included in the study. AZA was well tolerated by most patients, even in the long-term. Although there was no statistically significant difference in the reduction in number of actively inflamed joints between AZA-treated patients and controls, and AZA was no better in preventing progression of damage, AZA was still as good as the other medications. Consequently, AZA was often given to individuals who had not responded to other medications in the past. We provide illustrative case reports in which AZA also controlled psoriasis, and we conclude that, whereas AZA is not superior to other medications in the treatment of PsA, it may be safely used and it provides an alternative therapy for patients with PsA.

Abstract
OBJECTIVE To evaluate the efficacy of the cyclooxygenase-2 selective inhibitor celecoxib in treating patients with psoriatic arthritis (PsA) in flare. METHODS This 12-week, multicenter, randomized, double-blind, double-dummy, placebo-controlled, parallel-group study compared the efficacy and safety of celecoxib 400 mg (n=201) or celecoxib 200 mg (n=213) once daily (qd) with placebo (n=194) in treating the signs and symptoms of PsA in flare. The primary efficacy measure was the number of patients responding to treatment according to the American College of Rheumatology Responders Index 20% (ACR-20) at week 12. Efficacy and safety were assessed for all randomized patients who received at least 1 dose of study medication. RESULTS At the week-12 primary endpoint, approximately 50% of patients in each treatment group were responders according to the ACR-20 criteria, and no statistically significant treatment differences between treatment groups were observed. However, at week 2, the ACR-20 response rates for the celecoxib 400 mg (49%) and 200 mg (39%) groups were significantly higher than for the placebo group (28%) (P<0.001 and P=0.016, respectively). Within the celecoxib 400 mg group, ACR-20 response rates were similar at weeks 2, 6 (46%), and 12 (49%). In contrast, in the celecoxib 200 mg and placebo treatment groups, ACR-20 response rates increased 7 and 16%, respectively, from week 2 to week 6, and remained relatively unchanged from week 6 to week 12. There were no statistically significant differences in ACR-20 response rates between the celecoxib 400 mg and 200 mg groups at any time point. Treatment with celecoxib 200 and 400 mg qd was statistically superior to placebo treatment at weeks 2 and 6 for Patient's Assessment of Arthritis Pain. Both doses of celecoxib were well tolerated. CONCLUSIONS Celecoxib 400 mg and 200 mg qd were efficacious and well tolerated in treating the signs and symptoms of PsA in flare after 2 weeks of treatment. However, although the clinical effects of celecoxib 400 mg and 200 mg qd were observed for 12 weeks, there was a high placebo response at these time points, and there were no differences relative to placebo treatment at week 12.

Abstract
The aim of the present work is to compare drug survival and safety of infliximab, etanercept, and adalimumab (tumor necrosis factor [TNF] antagonists) in spondylarthritis (SpA) with those of rheumatoid arthritis (RA). To this purpose, we analysed the data in BIOBADASER (2000–2005), a drug registry launched in 2000 for long-term follow-up of the safety of these biologics in rheumatic diseases. The rates of drug discontinuation and adverse events (AEs) in SpA (n = 1,524) were estimated and compared with those of RA (n = 4,006). Cox regression analyses were used to adjust for independent factors. Total exposure to TNF antagonists for SpA was 2,430 patient-years and 7,865 for RA. Drug survival in SpA was significantly greater than in RA at 1, 2, and 3 years. The hazard ratio (HR) for discontinuation in SpA compared with RA was 0.66 (95% confidence interval [CI], 0.57–0.76) after adjustment for age, gender, and use of infliximab. The difference remained after controlling for the individual medication and its place in the sequence of treatment. There were fewer SpA patients with AEs (17%) than RA patients (26%; p < 0.001). The HR for AEs in SpA was 0.80 (95% CI, 0.70–0.91) compared with RA after adjustment for age, disease duration, and use of infliximab. In conclusion, due in part to a better safety profile, survival of TNF antagonists in SpA is better than in RA. TNF antagonists are at present a safe and effective therapeutic option for long-term treatment of patients with SpA failing to respond to traditional drugs. Because chronic therapy is necessary, continual review of this issue is necessary.

Abstract
Psoriatic arthritis is a common inflammatory arthritis associated with psoriasis, occurring in 5% to 40% of patients with cutaneous disease. Recently, there has been an increased appreciation of the need to use an integrated approach to these 2 diseases, considering both entities when determining therapeutic choices. In this review, the available therapeutic options for psoriatic arthritis are considered, along with the potential benefit that these medications may have for cutaneous psoriasis. Finally, a conceptual model for the therapy of psoriasis and psoriatic arthritis, the Four Quadrant Model, is presented as a simplified framework to use when considering treatment for psoriatic disease.

Abstract
In the majority of patients with psoriatic arthritis (PsA), it is a chronic progressive disease, and only 12% of patients with early PsA will be in disease-modifying antirheumatic drug-free remission at 2 years. Radiologic damage occurs in the early stages of PsA; up to 47% of patients with PsA have radiologic erosions after 2 years. This article reviews the clinical features of early PsA, pathologic insights into PsA gleaned from studies of early PsA, and the current state of diagnostic imaging and therapeutics in early PsA.

Abstract
The successful introduction of anti-tumor necrosis factor (TNF) therapies in psoriasis and psoriatic arthritis has sharpened considerable interest in this chronic and frequently disabling disease. Unlike the situation in rheumatoid arthritis, where anti-TNF therapies were introduced after years of painstaking research which confirmed a key proinflammatory role for TNF, the evidence for TNF having a key role in psoriatic arthritis has lagged behind. In this paper, the emerging immunohistochemical, genetic, and clinical literature relating to TNF's role in skin and joint manifestations of this disease is reviewed and areas for future research are suggested.

Abstract
OBJECTIVE Methotrexate is one of the most commonly used disease-modifying antirheumatic drugs in the management of psoriatic arthritis (PsA). Despite the differences between the inflammation in PsA and rheumatoid arthritis (RA), the effects of methotrexate on the synovium have been described solely in RA. In this study, we sought to determine the effects of methotrexate on the inflammatory infiltrate and on cytokine and metalloproteinase gene expression in the synovium of PsA patients. METHODS Ten patients with PsA (median duration 18 months) underwent arthroscopy and synovial biopsy of an inflamed knee before and after clinical improvement induced by methotrexate. Immunohistologic analysis was performed using antibodies to CD3, CD4, CD8, CD68, factor VIII, vascular cell adhesion molecule, E-selectin, and intercellular adhesion molecule (ICAM). Matrix metalloproteinase 3 (MMP-3) and tissue inhibitor of metalloproteinases 1 (TIMP-1) messenger RNA (mRNA) were quantified by competitive reverse transcription-polymerase chain reaction (RT-PCR). Interleukin-1alpha (IL-1alpha), IL-1beta, IL-2, IL-4, IL-5, IL-8, IL-10, IL-12p35, IL-12p40, IL-15, interferon-gamma (IFNgamma), and tumor necrosis factor alpha (TNFalpha) mRNA expression was quantified by real-time PCR. RESULTS Patients received a median methotrexate dosage of 13.75 mg/week (range 7.5-15) for a median of 11.5 months (range 7-14 months). The Ritchie Articular Index, swollen joint count, and Disease Activity Score were significantly reduced. There was a decrease in all immunohistologic staining, although this was statistically significant only for CD3, CD4, CD8, CD68, E-selectin, and ICAM. Despite clinical improvement in all patients, there was a residual T cell infiltrate in all synovial biopsy tissues. The synovial lining layer thickness, but not hypervascularity, was significantly reduced. There was also a significant reduction in MMP-3, but not TIMP-1, expression. Before treatment, PsA synovium was characterized by a predominant expression of the proinflammatory cytokines IL-15, IFNgamma, IL-1beta, and TNFalpha and the antiinflammatory cytokine IL-10. Methotrexate reduced synovial IL-1alpha, IL-1beta, IL-8, IL-10, IL-15, IFNgamma, and TNFalpha mRNA expression, but the effect was significant only for IL-8. CONCLUSION Methotrexate produced a clinical response in PsA by reducing, but not abolishing, the inflammatory infiltrate, adhesion molecule expression, and MMP-3 and proinflammatory cytokine gene expression, particularly IL-8, in the synovium. Methotrexate did not reduce hypervascularity, which is a prominent differentiating feature of PsA synovium.

Abstract
PURPOSE OF REVIEW Recently, there has been renewed interest in the spondyloarthropathy family of chronic inflammatory rheumatic conditions, which has been fueled to a large extent by the biologic era. Over the period of the past 2 years in particular, there have been several notable advances. First, there have been a number of large, high-quality randomized controlled trials evaluating the tumor necrosis factor (TNF) blockers and conservative treatments such as physiotherapy and nonsteroidal anti-inflammatory drugs for use in spondyloarthropathy. This has paved the way for the development of better tools to assess outcome in these patients both in daily practice and in the context of clinical trials. This review uses a systematic approach to outline the most recent (within the last 2 years) and the most pertinent advances in the treatments of the spondyloarthropathies, with particular emphasis on ankylosing spondylitis and psoriatic arthritis. RECENT FINDINGS Supervised group exercise programs maintain flexibility and posture in patients with ankylosing spondylitis, and spa therapy is a cost-effective treatment option in ankylosing spondylitis. Nonsteroidal anti-inflammatory drugs have a role in symptom modification and, more importantly, may prevent structural disease progression in patients with ankylosing spondylitis when administered continuously at a fixed dose. TNF blockers have been evaluated in a number of randomized controlled trials in ankylosing spondylitis and psoriatic arthritis and have been demonstrated to be safe and effective in the short-term management of these diseases. Longer-term trials are awaited with radiographic outcomes to comment on their disease-modifying properties and their long-term safety and efficacy profiles. SUMMARY There has been renewed interest in the spondyloarthropathy family of disorders, with an explosion in the number of trials evaluating outcome with the TNF blockers. To date, no cure has been found for the disease, but these agents are emerging as the best therapeutic option available for patients with ankylosing spondylitis and psoriatic arthritis to date.

Abstract
Etanercept is a subcutaneously administered biological response modifier that binds and inactivates tumour necrosis factor-alpha, a proinflammatory cytokine. In patients with early active rheumatoid arthritis, etanercept 25mg twice weekly was associated with a more rapid improvement in disease activity and a significantly greater cumulative response than methotrexate over 12 months of treatment in a randomised, double-blind trial. In addition, etanercept recipients showed a slower rate of radiographic progression and a more rapid improvement in quality of life than methotrexate recipients. The efficacy of etanercept was maintained at 3 years' follow-up. Etanercept was also significantly better than placebo at reducing disease activity in patients who had an inadequate response to previous treatment with disease-modifying antirheumatic drugs (DMARDs) in several well controlled trials. At study end (after 3 or 6 months' treatment), the percentage of patients achieving an American College of Rheumatology 20% (ACR20) response with etanercept (25mg or 16 mg/m(2) twice weekly) was 59 to 75% as monotherapy and 71% in combination with methotrexate; corresponding placebo response rates were 11 to 14% and 27%, respectively. Response has been maintained in patients who continued treatment for up to 5 years. In patients with psoriatic arthritis, etanercept 25mg twice weekly significantly reduced disease activity and improved skin lesions in two double-blind, placebo-controlled, 12- to 24-week trials. In the 24-week study, ACR20 response rates (50 vs 13%), psoriatic arthritis response rates (70 vs 23%) and the median improvement in skin lesions (33 vs 0%) were significantly greater in etanercept than in placebo recipients. In patients with polyarticular-course juvenile rheumatoid arthritis, etanercept resulted in improvements in all measures of disease activity and was significantly more effective than placebo at reducing disease flare. Eighty percent of patients receiving etanercept achieved a >or=30% reduction in disease activity over 7 months of treatment, and this was maintained for up to 2 years in a trial extension. Etanercept was generally well tolerated in children and adults in clinical trials; the most commonly occurring adverse effects included injection site reactions, infection, headache, rhinitis and dizziness. In conclusion, etanercept has emerged as an important new treatment option in inflammatory arthritis. Etanercept provides rapid and sustained improvements in disease activity in patients with early and DMARD-refractory rheumatoid arthritis and has been shown to inhibit radiographic progression in those with early disease. Well controlled studies have also demonstrated the efficacy of etanercept in patients with psoriatic arthritis or polyarticular-course juvenile rheumatoid arthritis.

Abstract
Psoriatic arthritis (PsA) is considered to be one of the spondyloarthritides, and as such has both spinal and peripheral joint involvement. In 80% of patients, psoriasis usually precedes the development of arthritis. Although there are no widely accepted diagnostic criteria, a number of distinct clinical features allow it to be distinguished from other forms of inflammatory arthritis. It affects both sexes equally, and the pattern of joint involvement is characteristic with distal interphalangeal joint involvement, asymmetry, dactylitis, flail or ankylotic deformities of digits, and the frequent presence of enthesitis and spinal involvement. It may have a pattern of joint involvement similar to rheumatoid arthritis (RA) but in these patients rheumatoid factor and the other systemic features of RA are usually absent. Radiographs frequently reveal evidence of asymmetric sacroiliitis and spinal disease, and peripheral joints, as well as showing erosions, may also demonstrate profuse new bone formation and ankylosis. Profound osteolysis producing the pencil-in-cup deformity can also occur in the same individual. It is now recognised that PsA can be a destructive arthritis with an increased morbidity and mortality. Studies of standard disease-modifying therapies have been small and frequently inconclusive because of a high placebo response rate. This may be as a result of heterogeneity in patient selection, poor assessment tools, or the difference in underlying pathogenesis and subsequent response to therapy. In meta-analyses, sulfasalazine and methotrexate have been shown to be effective. Treating the skin alone seems to have little impact on joint disease, and the relationship between skin and joints is still unclear. However, recent studies with anti-tumour necrosis factor agents, such as etanercept and infliximab, have shown considerable significant clinical benefit and provided the hope that we will at last have effective therapies for this disease.

Abstract
Psoriatic arthritis (PsA), an inflammatory arthritis associated with psoriasis, can lead to disability from progressive joint destruction and bony fusion. To date, conventional disease modifying antirheumatic drugs (DMARDS) have not convincingly lessened joint pain and inflammation in PsA and there is very little data on the limitation of radiographic progression with these agents. The biological agent etanercept (Enbrel, Amgen, Inc, Thousand Oaks, California, USA) is a soluble TNF receptor fusion protein with proven efficacy in the treatment of rheumatoid arthritis (RA). In a Phase II and Phase III trial, conducted in moderate-to-severe PsA, etanercept significantly reduced joint pain and swelling and lowered the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level. A significant decline in structural damage was observed as early as 6 months after starting the drug. Etanercept also improved quality of life measures (Health Assesment Questionnaire [HAQ] and global assessment scores). Up to a third of patients experienced transient injection-site reactions. Rare cases of opportunistic infection, demyelinating disorders and aplastic anaemia have been reported, but a causal link has not been established. In summary, etanercept is a safe and effective agent for the treatment of PsA and represents a major advance in the therapy of this potentially crippling disease.

Abstract
UNLABELLED Few prospective placebo-controlled studies have evaluated disease-modifying antirheumatic drugs (DMARDs) in the treatment of peripheral psoriatic arthritis. OBJECTIVE To evaluate second-line treatments used in clinical practice in patients with psoriatic arthritis. METHOD We studied a cross-section of 100 consecutive patients seen by hospital-based or office-based rheumatologists for psoriatic arthritis. PATIENTS The 55 men and 45 women had a mean age of 48 years (range, 17-79 years) and a mean disease duration of 7 years (range, 1-24 years). RESULTS The most commonly used DMARDs were sulfasalazine, gold, methotrexate, and hydroxychloroquine (64, 43, 41 et 17 patients, respectively). These drugs had been stopped because of inefficacy in 31%, 31%, 12%, and 53% of patients, respectively, and because of adverse events in 23%, 44%, 22%, and 41% of patients, respectively. At the time of the study, mean treatment durations were 15, 21, 34, and 12 months, respectively, and the drugs were still being used in 45%, 21%, 66%, and 6% of patients. CONCLUSION Our data confirm the value of methotrexate and salazopyrine. Methotrexate had the best risk/benefit ratio. Gold was often responsible for side effects. Hydroxychloroquine was inadequately effective and poorly tolerated.

Abstract
Leflunomide was recently approved for the treatment of rheumatoid arthritis. Its role in the treatment of psoriasis and psoriatic arthritis is unclear. Twelve consecutive psoriatic arthritis patients who had not responded to at least one disease modifying anti-rheumatic drug (DMARD) were started on leflunomide alone or in addition to another DMARD. Global assessment of improvement in psoriasis and psoriatic arthritis by the treating rheumatologist was scored on a 0-3 scale. After 2-3 months of treatment, 8 patients had moderate to marked improvement in both psoriasis and psoriatic arthritis. The improvement in modified tender joint counts, patient's global assessments, and grip strengths was statistically significant. However, physicians' global assessments and the modified swollen joint counts did not reach a significant difference. Three patients whose toxicity necessitated the temporary discontinuation of the drug were able to resume the drug at lower dosage with clinical benefit. Leflunomide may prove to be a useful agent for the treatment of recalcitrant cases of psoriasis and psoriatic arthritis.

Abstract
BACKGROUND Etanercept, a tumour-necrosis-factor inhibitor, has shown efficacy in the treatment of rheumatoid arthritis. Psoriatic arthritis and psoriasis are disease states in which tumour necrosis factor, a proinflammatory cytokine, is present in increased concentrations in joints and in the skin. Therefore, psoriatic arthritis and psoriasis may be appropriate therapeutic targets for etanercept. METHODS This randomised, double-blind, placebo-controlled, 12 week study assessed the efficacy and safety of etanercept (25 mg twice-weekly subcutaneous injections) or placebo in 60 patients with psoriatic arthritis and psoriasis. Psoriatic arthritis endpoints included the proportion of patients who met the Psoriatic Arthritis Response Criteria (PsARC) and who met the American College of Rheumatology preliminary criteria for improvement (ACR20). Psoriasis endpoints included improvement in the psoriasis area and severity index (PASI) and improvement in prospectively-identified individual target lesions. FINDINGS In this 12 week study, 26 (87%) of etanercept-treated patients met the PsARC, compared with seven (23%) of placebo-controlled patients. The ARC20 was achieved by 22 (73%) of etanercept-treated patients compared with four (13%) of placebo-treated patients. Of the 19 patients in each treatment group who could be assessed for psoriasis (> or = 3% body surface area), five (26%) of etanercept-treated patients achieved a 75% improvement in the PASI, compared with none of the placebo-treated patients (p=0.015). The median PASI improvement was 46% in etanercept-treated patients versus 9% in placebo-treated patients; similarly, median target lesion improvements were 50% and 0, respectively. Etanercept was well tolerated. INTERPRETATION Etanercept offers patients with psoriatic arthritis and psoriasis a new therapeutic option for control of their disease.

Abstract
Psoriatic arthritis occurs in 5 - 42% of patients with psoriasis. It is an inflammatory arthritis distinct from rheumatoid, being usually sero-negative, asymmetrical and often affecting the spine, sacro-iliac and distal interphalangeal joints. It runs a very variable course, from a mild non-destructive disease to a severe rapidly progressive erosive arthropathy, producing an 'arthritis mutilans' with a combination of bone lysis and joint ankylosis. Its pathogenesis is not as well understood as rheumatoid arthritis, but is thought to be similarly immune driven, with a qualitatively similar immunomodulatory cascade and cytokine profile. Quantitatively, however, there are distinct differences in cell ratios and cytokine levels that may well impact on therapeutic strategies. Current therapies, such as methotrexate and sulphasalazine, have yet to be shown to be significantly more effective than placebo in delaying damage and produce only marginal improvements in symptoms. The newer specific biological agents, such as the anticytokine antibodies, interleukins and more specific anti-T-cell therapies, are starting to be studied in psoriatic arthritis. The rationale for their use comes mostly from extrapolation of their efficacy in rheumatoid arthritis. It has yet to be seen whether they will be efficacious in treating the osteolysis, fibrosis and new bone formation particular to psoriatic arthritis. Any treatment for the arthritis must also help the skin. Greater understanding of psoriatic arthritis, its pathogenesis and natural history is required if we are to target these exciting but expensive therapies effectively.

Abstract
A 25-year-old man who played summer softball developed bilateral shoulder pain. The pain was not alleviated by decreased activity, and signs and symptoms, including previous bilateral foot pain that developed before the onset of a psoriatic scalp lesion, suggested psoriatic arthritis (PA). Bilateral pain is unusual with PA; more typically, patients have monarticular pain (see "Asymmetric Presentation of Psoriatic Arthritis," below). Discussed are differential diagnosis, etiology, clinical features, and treatment, including physical therapy, NSAIDs, and disease-modifying agents such as sulfasalazine.
