Abstract
Before becoming a cornerstone in the treatment of numerous immune-mediated diseases, mycophenolate mofetil (MMF) was first introduced as an immunosuppressive agent in transplant immunology and later received the attention of rheumatologists and clinicians involved in the management of autoimmune diseases. MMF is now a widespread immunosuppressive drug for the treatment of several conditions, including lupus nephritis, interstitial lung disease associated with systemic sclerosis, and anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis while being efficacious also as rescue therapy in various orphan diseases, including dermatomyositis and IgA-associated nephropathy. Similarly, case reports or series support a possible use of MMF in other rare autoimmune diseases. Beyond modulating lymphocyte activation, MMF acts on other immune and non-immune cells and these effects may explain the therapeutic profile of this medication. The effects of MMF are broadly characterized by the impact on the immune system and the antiproliferative and antifibrotic changes induced. In this latter case, mechanistic data on fibroblasts may in the future allow to reevaluate the use of MMF in selected patients with inflammatory arthritis or systemic sclerosis. Attention must be paid towards the possible occurrence of adverse events, such as gastrointestinal complaints and teratogenicity, while the risk of infections and cancer related to MMF needs to be further investigated.

Abstract
BACKGROUND There is a significant association between psoriasis and inflammatory bowel disease (IBD). Many treatments for psoriasis and psoriatic arthritis are also used for IBD. OBJECTIVE To assess therapeutic options for patients with psoriasis and concurrent IBD. METHODS A systematic literature search was performed for clinical studies of biologic and systemic psoriasis medications in psoriasis, psoriatic arthritis, ulcerative colitis, and Crohn's disease, for the period from January 1, 1947, to February 14, 2017. Randomized, controlled, double-blinded studies were selected if available. If not, the next highest level of available evidence was selected. RESULTS Of the 2282 articles identified, 132 were selected. Infliximab and adalimumab have demonstrated efficacy in psoriasis, psoriatic arthritis, ulcerative; colitis, and Crohn's disease. Ustekinumab has demonstrated efficacy in psoriasis, psoriatic arthritis, and Crohn's disease. Certolizumab has demonstrated efficacy in psoriatic arthritis and Crohn's disease. Etanercept, secukinumab, brodalumab, and ixekizumab have demonstrated efficacy in psoriasis and psoriatic arthritis but may exacerbate or induce IBD. Guselkumab has demonstrated efficacy in psoriasis. LIMITATIONS There are no known clinical trials of treatment specifically for concurrent psoriasis and IBD. CONCLUSIONS Infliximab and adalimumab have demonstrated efficacy in psoriasis, psoriatic arthritis, ulcerative colitis, and Crohn's disease; other agents have demonstrated efficacy for some, but not all, of these indications.

Abstract
Mycophenolate mofetil (MMF) is an immunosuppressive drug the efficiency of which has been established in renal transplantation. Recent studies suggest that it may also be effective in the treatment of variant skin diseases especially if the skin lesions are triggered by lymphocytes. Studies have shown efficacy in autoimmune bullous dermatoses, atopic dermatitis and psoriasis. However, there are no placebo-controlled trials that support the use of MMF as first line therapy in these skin diseases.

Abstract
Background: Mycophenolate mofetil (MMF) is an immune suppressant that selectively inhibits activated lymphocytes. Its usefulness in treating psoriasis has not been systematically investigated. Objective: To evaluate efficacy and safety of MMF as a monotherapy for psoriasis. Methods: This is a two-center, prospective, open-label clinical trial. Results: Twenty-three patients with moderate to severe psoriasis [mean psoriasis area and severity index (PASI) of 21.7] were treated with MMF 2–3 g/day for 12 weeks. Eighteen patients completed the study. The PASI was reduced by 24% ( p < 0.001) at 6 weeks, and by 47% ( p < 0.001) at 12 weeks. At the end of the treatment phase, 77% of the patients had significant reduction of PASI while 22% did not respond. The treatment was well tolerated. Five patients experienced mild nausea. One patient each had periorbital edema and pruritus. One patient had transient leukopenia. Conclusion: In this noncontrolled trial, the majority of patients with moderate to severe psoriasis responded to mycophenolate mofetil monotherapy with few adverse events. A randomized, controlled trial should be considered to confirm the usefulness of MMF as a monotherapy for psoriasis.

Abstract
Psoriasis is a potentially debilitating inflammatory dermatosis affecting 0.2%-4.8% of the population worldwide causing a significant occupational, personal or psychosocial morbidity to these patients for life. The basic aim of psoriasis therapy is to control the disease to maximum possible extent and improve the patient’s quality of life. Management of triggers for flare-ups, lifestyle modifications, and dietary supplements are often recommended. Intermittent or rotational therapy with frequent alterations in treatment options is usually needed to reduce toxicity of anti-psoriatic drugs in the absence of safer alternatives. Currently, several biological agents categorized as either T-cell targeted (e.g., Alefacept, Efalizumab) or cytokine modulating (e.g., Adalimumab, Infliximab, Etanercept) are available for treating severe psoriasis. However, their high cost is often precluding for most patients. The usefulness of systemic (methotrexate, cyclosporine, acitretin or several other therapeutic agents) or topical (tar, anthralin, corticosteroids or calcipotriol ointments, phototherapy with or without psoralens) therapies has been well established for the management of psoriasis. The literature is also replete with benefits of less used non-standard and unconventional treatment modalities (hydroxycarbamide, azathioprine, leflunomide, mycophenolate mofetil, isotretinoin, fumarates, topical calcineurin inhibitors, peroxisome proliferator-activated receptors agonists, statins, sulfasalazine, pentoxifylline, colchicine, grenz ray therapy, excimer laser, climatotherapy and balneophototherapy, peritoneal dialysis, tonsillectomy, ichthyotherapy, etc.). These can be used alternatively to treat psoriasis patients who have mild/minimal lesions, are intolerant to conventional drugs, have developed side effects or achieved recommended cumulative dose, where comorbidities pose unusual therapeutic challenges, or may be as intermittent, rotational or combination treatment alternatives.

Abstract
BACKGROUND Mycophenolate mofetil is a well-known immunosuppressive agent in transplantation medicine. The efficacy of enteric-coated mycophenolate sodium (EC-MPS) was confirmed in other inflammatory skin diseases, including atopic dermatitis and SCLE. OBJECTIVE To investigate the efficacy and the tolerability/short-term safety of EC-MPS in patients with moderate to severe chronic plaque psoriasis. PATIENTS AND METHODS An open-label pilot study in which 20 patients with a PASI >10 received EC-MPS 720 mg twice daily for 6 weeks followed by 360 mg twice daily for another 6 weeks. Patients who completed 12 weeks of treatment were followed-up for an additional 12 weeks. Treatment outcomes were assessed with PASI50% and PASI75%. RESULTS Eighteen men and two women (mean age 46 years) entered the study. Sixty-five percent (13/20) finished the treatment period. By week 6, no patient achieved PASI 75% and 8/20 patients achieved a PASI 50%. Compared to week 6, 4/13 showed a deterioration of their psoriasis at week 12. Twenty-five percent (2/8) achieved a PASI 75% in week 24. The most-reported adverse events were itching (30%), diarrhea (10%), and a reversible elevation of the triglycerides level. CONCLUSION EC-MPS does not seem effective as monotherapy for moderate to severe psoriasis, but might be used at a dosage of 1440 mg daily in well-selected patients with treatment-resistant psoriasis.

Abstract
In recent years a considerable number of imaging techniques have been used to demonstrate the onset and progression of arthritis-related changes in psoriatric arthritis (PsA). Moreover the identification of new immunological pathways has resulted in a substantial improvement of available therapies for PsA increasing the chance for the individual to receive effective treatment. Although an all-embracing disease activity score is still lacking, there is a variety of symptom-related tools to adequately reflect the course of disease and to evaluate the corresponding treatment success. This manuscript aims to give an overview of the latest corresponding knowledge with respect to PsA.

Abstract
Originally used to treat psoriasis nearly three decades ago, mycophenolic acid, reformulated as mycophenolate mofetil (MMF), has been rediscovered by the world of dermatology. As a relatively well-tolerated immunosuppressive used in organ transplant recipients, MMF has recently been reported to show promise for several dermatologic conditions, including psoriasis, pemphigus vulgaris, pyoderma gangrenosum, bullous lichen planus, and even connective tissue diseases such as lupus erythematosus and dermatomyositis. Although not intended to be exhaustive, this review discusses MMF with regard to its basic pharmacology, its side effects, and its reported efficacy in a variety of dermatologic indications. Relevant literature was retrieved by a Medline search combining the terms "mycophenolate" or "mycophenolic acid" and "skin" or "skin disease" or a number of specific conditions ("psoriasis", "dermatitis", "eczema", "pemphigoid", "pemphigus", "vasculitis", "pyoderma gangrenosum", "Crohn's disease", "graft-versus-host disease", "lichen planus"). As MMF has only been recently re-introduced for dermatologic application, the nature of much of the literature is admittedly that of case reports or case series. Nevertheless, the results are sufficiently promising to warrant further larger, control studies.

Psoriasis is a common, chronic, inflammatory, multisystem disease with predominantly skin and joint manifestations affecting approximately 2% of the population. In this fourth of 6 sections of the guidelines of care for psoriasis, we discuss the use of traditional systemic medications for the treatment of patients with psoriasis. Treatment should be tailored to meet individual patients' needs. We will discuss in detail the efficacy and safety, and offer recommendations for the use of the 3 most commonly used, and approved, traditional systemic agents: methotrexate, cyclosporine, and acitretin. We will also briefly discuss the available data for the use of azathioprine, fumaric acid esters, hydroxyurea, leflunomide, mycophenolate mofetil, sulfasalazine, tacrolimus, and 6-thioguanine in psoriasis.

Abstract
Although most psoriasis patients respond to standard therapies, many circumstances warrant the use of nonstandard or off-label treatments. For instance, patients with treatment-resistant psoriasis or those who have had multiple adverse effects to other therapies may be good candidates for off-label treatments. Similarly, patients with unusual and hard-to-treat forms of psoriasis such as pustular psoriasis and palmoplantar psoriasis or specific comorbidities may benefit from certain nonstandard therapies. Drugs that may be used as alternatives to standard therapies include mycophenolate mofetil, tacrolimus or pimecrolimus, isotretinoin, colchicine, sulfasalazine, paclitaxel, dapsone, azathioprine, and hydroxyurea. Other unconventional therapies include climatotherapy at the Dead Sea and grenz ray therapy.

Abstract
Cutaneous manifestations in renal transplant recipients are frequently represented by infections and cancerous lesions. However, dermatologic lesions secondary to autoimmune diseases are rare. We report a case of pustular psoriasis occurring after renal transplantation in a 31-year-old woman with a history of vitiligo. The patient was on hemodialysis for 2 years for undetermined chronic nephropathy. She received an HLA identical live related transplant from her brother. She was maintained on an immunosuppressive regimen of corticosteroids, azathioprine, and cyclosporine, which was replaced with mycophenolate mofetil because of neurotoxicity and azathioprine was stopped. Thirty-one months after renal transplantation, she developed pustular psoriasis which was treated with retinoids; she experienced a relapse and resistance to treatment despite the reintroduction of cyclosporine.

Abstract
Mycophenolate mofetil (MMF) is a new immunosuppressant recently introduced in the treatment of autoimmune conditions. The greatest experience with the use of MMF has been achieved in the treatment of proliferative lupus glomerulonephritis. However, MMF has also been used to control SLE extra-renal manifestations as well as other autoimmune rheumatic diseases such as idiopathic inflammatory arthropathies, inflammatory myopathies, systemic sclerosis, and systemic vasculitis. MMF seems to be well tolerated and effective and could be considered a useful alternative to standard immunosuppressants for the treatment of autoimmune rheumatic disorders. However, further studies are needed in order to determine its real place in the treatment of these conditions. In this paper, the use of MMF in different autoimmune rheumatic diseases is reviewed and discussed.

Abstract
BACKGROUND There are numerous studies that individually evaluate the efficacy/effectiveness and toxicity of drugs in the systemic treatment of psoriasis. On the contrary, we can hardly find studies that compare each other. OBJECTIVE To evaluate and compare the effectiveness and toxicity of mycophenolate mofetil and cyclosporin in chronic plaque psoriasis through a prospective, sequential, cross-over, non-randomized, two-phase, open-label study. PATIENTS/METHODS Eight patients (five women and three men; mean age 57, range 35-78) with moderate-to-severe chronic plaque psoriasis were included in the study. They were treated with oral mycophenolate mofetil (30 mg/kg/day) over a period of 16 weeks. Following a variable washout period and after a new outbreak of the disease, oral cyclosporin was introduced at a dose of 4 mg/kg/day. During both treatment regimens, follow-up visits were performed at 3, 8 and 16 weeks. RESULTS In both groups, the PASI started to decrease once treatment was begun. Cyclosporin was faster and statistically a lot more effective than mycophenolate mofetil, reaching a higher number of complete remissions and better percentages of PASI improvement from baseline (45.7%, 60.2% and 60.5% at 3, 8 and 16 weeks respectively for mycophenolate mofetil, and 89.7%, 95.3% and 95.3% respectively at the same intervals for cyclosporin). Cyclosporin was also more predictable in its action as the percentage of improvement along the follow-up visits had a much wider range for mycophenolate mofetil. Overall, the tolerability of both drugs was good. None of the patients had to discontinue treatment because of an adverse event. Two patients treated with cyclosporin showed increased plasma levels of creatinine. CONCLUSIONS Cyclosporin is more effective, fast, and predictable in its effect than mycophenolate mofetil to control moderate-to-severe chronic plaque psoriasis. Both drugs are well tolerated in short courses of treatment.

Abstract
Psoriatic arthritis (PsA) is a chronic, autoimmune, seronegative inflammatory arthritis characterized by varying degrees of axial and peripheral arthritis. Here, we review the literature on the pharmacological management of PsA and present a simple treatment algorithm based on the available information. Although PsA management must be individualized to the degree and type of joint pain and inflammation, in general, nonsteroidal antiinflammatory drugs (NSAIDs) still represent first-line treatment of mild PsA. Second-line therapy includes older agents such as gold salts, methotrexate, sulfasalazine, and cyclosporine. The tumor necrosis factor alpha (TNF-alpha) antagonists represent the most recent major advance in the clinical management of PsA.

Abstract
Immunosuppressive drugs are the backbone of solid organ transplantation. The introduction of new immunosuppressive drugs led to improved patient and organ survival rates. Nowadays, acute rejection can be reduced to a minimum. Individualization and avoidance of drug-related adverse effects became a new goal to achieve. The potency of immunosuppressive drugs makes them attractive for use in various autoimmune diseases; therefore, the experience on immunosuppressive drugs outside the field of organ transplantation is analysed in this review.

Abstract
Psoriasis is a relatively common, chronic skin disease affecting 1-2% of the population in the developed countries. It is an inflammatory, autoimmune skin disorder characterised by an accelerated rate of epidermal proliferation and disordered differentiation. Since our last review in 1999, considerable progress has been made in understanding the immunopathogenesis of this disease, and new drugs have become available for its treatment. Recent clinical trials showed the efficacy of novel biotechnology approaches, such as blocking tumour necrosis factor-alpha or T-cell-mediated immune response by the anti-CD2, anti-CD11a, anti-B7, anti-CD4 or anti-CD25 approaches. Agents which block type 1 cytokines or skew immune reactions into type 2 are other promising approaches. Other possible targets are chemokines and their receptors, the cytokines and receptors involved in T cell trafficking into the skin, and peroxisome proliferator-activated receptors. Relatively little development is reported of the drugs targeting the keratinocyte or the classical antipsoriatic compounds which include glucocorticoids, vitamin D derivatives and cytostatic agents.

Abstract
Further understanding of the pathogenesis of dermatologic conditions at a molecular level has led to targeted therapies. The topical immune response modifiers have contributed significantly to the treatment of cutaneous diseases. New topical remedies, particularly the Toll-like receptor agonists and calcineurin inhibitors, have added to the clinical armamentarium and have further advanced clinicians' ability to treat a wide variety of benign, premalignant, and malignant conditions. Furthermore, these agents have contributed to the understanding of the disease process. The next decade will witness even greater advances in targeted immunotherapies for dermatologic disease.

Abstract
In addition to corticosteroids, dermatologists have access to an array of immunomodulatory therapies. Azathioprine, cyclophosphamide, methotrexate, cyclosporine, and mycophenolate mofetil are the systemic immunosuppressive agents most commonly used by dermatologists. In addition, new developments in biotechnology have spurred the development of immunobiologic agents that are able to target the immunologic process of many inflammatory disorders at specific points along the inflammatory cascade. Alefacept, efalizumab, etanercept, and infliximab are the immunobiologic agents that are currently the most well known and most commonly used by dermatologists. This article reviews the pharmacology, mechanism of action, side effects, and clinical applications of these therapies.

Abstract
Immune response modifiers (IRMs) are agents that target the body's immune system (i.e., cytokines, receptors, and inflammatory cells) to combat disease. Topical IRM therapies, which encompass both proinflammatory and immunosuppressive therapeutics, have been used to successfully treat a number of dermatologic conditions. Proinflammatory treatments include Toll-like receptor agonists (e.g., imiquimod 5% cream) and interferon (e.g., interferon-alpha) therapies, which have been used in the treatment of external genital warts, basal cell carcinoma, and other dermatologic diseases. Immunosuppressive therapies include topical and intralesional corticosteroids, anti-tumor necrosis factor agents (e.g., infliximab and etanercept), and anti-CD4+ T-cell agents, including calcineurin inhibitors and mycophenolate. These agents have been used to treat a number of conditions, including atopic and seborrheic dermatitis and psoriasis. This article reviews the mechanism of action of IRMs and the application of IRMs in several dermatologic diseases.

Abstract
Progress in the understanding of psoriasis as a T-cell mediated inflammatory disease has led to the development of new immunomodulatory therapies. Currently the main focus is on the so-called biologics (or biological agents), including fusion proteins, monoclonal antibodies, cytokines and selective receptors. They mainly target single steps in the complex cascade of humoral and cellular inflammatory immuno-mechanisms that finally lead to the accelerated growth of epidermal and vascular cells in the psoriatic lesions. The most promising and advanced biological agents are discussed along with their influence on the critical pathophysiological steps in psoriasis, including depletion of T cells, blockade of initial T-cell activation and T-cell receptor (TCR) stimulation, blockade of costimulatory signals and T-cell proliferative signals as well as restoration of the T helper type 1 (Th1)/Th2 balance by diminishing type 1 cytokines and administration of type 2 cytokines. In addition to the biological agents, further development of 'classical' dermatological therapies, such as retinoids, or the discovery of new indications for non-dermatological agents contribute to the novel pharmacological approaches in the treatment of psoriasis.

Abstract
Psoriatic arthritis (PsA) is a destructive form of inflammatory arthritis that occurs in about one-third of patients with psoriasis. The pathogenesis of PsA includes genetic and immunological factors. A review of the currently available therapies reveals that traditional disease-modifying medications have provided only marginal relief from joint inflammation in patients with PsA, and have not been successful in controlling the disease and preventing joint damage. On the basis of current understanding of the pathogenesis of joint destruction in PsA, several new medications have been introduced, including anti-tumour necrosis factor (TNF) agents and agents that interfere with T-cell function. Most of these medications have been found to be effective in both psoriasis and PsA. Recent randomised controlled trials suggest that at least anti-TNF agents may help prevent progression of joint destruction.

Abstract
BACKGROUND Mycophenolate mofetil (MMF) has been shown to be effective for systemic treatment of psoriasis. MMF is the prodrug of mycophenolic acid (MPA), the pharmacologically active compound. The measurement of plasma MPA levels could be useful for optimizing therapeutic management using MMF. OBJECTIVES To investigate whether plasma trough levels of MPA correlate with the efficacy and safety of oral MMF in the treatment of patients with psoriasis. METHODS Six patients (four women and two men, mean age 58 years) with severe chronic plaque-type psoriasis were treated with oral MMF 1 g twice daily. The Psoriasis Area and Severity Index (PASI), routine laboratory examinations and plasma MPA trough levels, measured by an enzyme-multiplied immunoassay (EMIT), were determined at 2 weeks and 1, 3, 5 and 7 months. RESULTS All the patients experienced a marked improvement within the first 15 days and continued to do so for 5-7 months. Two patients achieved complete remission. MMF was well tolerated. MPA levels showed a wide intra- and interindividual variability. There was no significant correlation between MPA trough levels and the reduction of the PASI or the presence of adverse effects, but a good correlation with therapeutic compliance. CONCLUSIONS The monitoring of MPA trough levels with EMIT appears to be a poor predictor of efficacy or toxicity. In contrast, it is a useful tool to evaluate the degree of therapeutic compliance.

Abstract
Many systemic agents are used in the treatment of psoriasis. They provide good control of psoriasis in the majority of patients and have improved their life quality indices. Frequently, combination therapy is utilized to synergize the efficacy of these medications. Many dermatologists are hesitant in prescribing systemic agents because of their adverse effects. However, such potential toxicities arising from these medications can largely be avoided if proper patient selection and close monitoring are performed.

Abstract
This article examines immunosuppressant transplant agents used to treat the various rheumatic diseases. The older drugs of this type have been used in this dual role for decades. There is a new generation of immunosuppressant drugs with established use in the arena of transplantation medicine. Only recently have the potential rheumatologic applications for these agents been investigated. The authors review in depth the published experience with the newer agents. The authors also discuss novel rheumatologic uses for the older agents that have been described within the past year.

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
The current standard systemic therapeutic modalities for psoriasis have many potential side effects. Progress made in the understanding of the pathophysiology of psoriasis as a T-cell-mediated dermatosis provide options for new more precise therapeutic approaches. These immunological therapeutic strategies involve the inhibition/depletion of activated T-lymphocytes, the inhibition of antigen presentation and thus the regulation of T-cell activation, the inhibition of adhesion of inflammatory cells, the inhibition of effects of proinflammatory mediators and the administration of antiinflammatory cytokines. This article summarizes these new systemic therapeutic approaches. Clinical results in the early studies have been mixed. In the next years further results of phase II- and phase Ill-studies may be expected, which should allow better assessment of the potential of those particular approaches. Some of these approaches could lead to the approval of new drugs to treat psoriasis and to enhance or replace already existing therapeutic options. Furthermore results of therapeutic experiments should contribute to a better understanding of the disease. As we learn which mechanisms are more or less important for the disease, we will be better able to plan intervention strategies.

Abstract
Psoriasis in the elderly will constitute a significant challenge for the practising physician in this new millennium. Special considerations for the elderly include drug-induced or drug-aggravated psoriasis, especially for patients receiving polypharmacy or with recent worsening or poor response to conventional therapy. Other frequently encountered forms of psoriasis in the elderly include psoriatic arthritis and its complications, inverse psoriasis and potentially life-threatening complications such as erythrodermic or acute pustular psoriasis, where early recognition and systemic therapy is critical. Faced with an array of topical and systemic drug therapy options, it is of paramount importance that the physician remains focused on the holistic management of the patient, in order to achieve optimal compliance and benefit. This can be achieved through careful attention to quality-of-life issues, especially since many elderly patients may have other medical, social and economic comorbidities that can further negatively affect their overall quality of life. It is also essential that the severity of psoriasis be assessed on a more balanced, holistic scale that incorporates both physical and psychological parameters, such as the Salford Psoriasis Index. The patient and caregiver education should be multi-faceted, regularly conducted and practically orientated. Treatment goals should be kept simple and individualised for each patient, based on concomitant comorbidities, potential adverse effects, existing quality of life, self-care capability, drug history, caregiver situation, financial needs, feasibility for follow-up and patient's preferences. Topically applied medications, such as topical corticosteroids, salicylic acid, tar and dithranol preparations, calcipotriol and tazarotene, are the favoured first-line therapeutic options in the elderly. Narrowband ultraviolet B phototherapy is also well established as a standard therapy for psoriasis. Systemic therapy with agents such as methotrexate, acitretin and cyclosporin should be judiciously reserved for severe, extensive cases in view of their lower therapeutic index in the elderly. The ambulatory psoriasis treatment centre is an integral part of the overall cost-effective management of patients with psoriasis that can function as a 'one-stop' treatment and resource centre for the elderly patient.

Abstract
Relapsing idiopathic nodular panniculitis is the term used to describe a group of diseases that presents as subcutaneous inflammatory nodules, fever and systemic symptoms and histopathologically displays inflammation within the fat lobules. There is no specific test for diagnosis and extensive investigations are required to exclude systemic causes of panniculitis. No uniform effective therapy is available and various drugs used include mainly corticosteroids alone or in combination with other immunosuppressive agents. Presented in this paper is an intractable case of idiopathic nodular panniculitis whose corticotherapy failed and could not be continued because of serious adverse effects. The rapid and good therapeutic response of the patient to mycophenolate mofetil monotherapy is discussed.

Abstract
In the past decade, there has been enormous progress in the understanding of the pathomechanisms of immune-mediated diseases, which has led to major advances in immunotherapeutic strategies. As a consequence, the armamentarium of specific and nonspecific immune-modulating and immunosuppressive drugs for the treatment of skin diseases has been widely extended. Among the nonspecific immunomodulators, mycophenolate mofetil and leflunomide show promising effects in a variety of autoimmune and inflammatory skin disorders. Both compounds inhibit a key enzyme in nucleotide biosynthesis, a step that is pivotal for the production of cytotoxic T cells and antibody formation. They do not act in the nucleus, which may explain their advantageous side-effect profile.

Abstract
Psoriatic arthritis is a chronic inflammatory arthropathy which can be distinguished from rheumatoid arthritis on the basis of differing patient demographics, genetic predisposition, histopathologic change, radiographic appearance, and clinical course. The cause of psoriatic arthritis remains unknown but appears to be autoimmune in nature as its pathogenesis is characterized by persistent synovial inflammation resulting in damage to the articular cartilage and osteolysis. Compared with rheumatoid arthritis, distinct lymphocyte subpopulations and pro-inflammatory cytokine levels appear to be present within the joint but the importance and therapeutic implications of these differences is uncertain. The clinical presentation of psoriatic arthritis is variable and overlapping patterns of joint involvement affecting both the appendicular and axial skeleton are seen. For patients with mild synovial disease and a favorable prognosis, the use of a nonsteroidal anti-inflammatory drug for symptomatic relief is often sufficient. However, the destructive potential of psoriatic arthritis is increasingly recognized and patients with more synovial disease and radiographic change at presentation appear to be at risk for greater morbidity and increased mortality. Immunomodulating therapy has the potential to suppress joint inflammation and preserve functional capacity but true disease modification has yet to be shown. The toxicity associated with presently available immunomodulatory agents makes careful patient selection and conscientious monitoring essential. The efficacy of methotrexate and sulfasalazine in patients with psoriatic arthritis is well defined while more anecdotal reports of benefit exist for other agents including the antimalarials, azathioprine, colchicine, cyclosporine, and the retinoids. For all treatment regimens, the magnitude of clinical improvement demonstrated to date has been rather small and quite subjective in character with few controlled studies of adequate size and duration having been reported. Emerging biologic therapies, such as those which target tumor necrosis factor, will hopefully provide future treatment options with greater efficacy and improved safety for patients with psoriatic arthritis.

Abstract
New insights into the pathophysiology of psoriasis have suggested possibilities for targeted therapeutic intervention. Several novel, systemic immunomodulatory therapies are currently in clinical development and results of recent clinical trials are remarkable. These include approaches targeting antigen presentation and costimulation, T-cell activation and leukocyte adhesion, the action of proinflammatory mediators and the administration of anti-inflammatory cytokines. These trials contribute to our further understanding of the disease, indicating which mechanisms play a greater or lesser part in its development. Moreover, they will lead to new therapeutic options. If psoriasis is considered as a visible model disease for T-cell-mediated disorders characterized by a type-1 cytokine pattern these recent findings might have a more general impact on the treatment of autoimmune disorders.

Abstract
BACKGROUND Immunosuppressive treatments have been associated with an increased risk of skin cancer, especially in patients who have had organ transplants. We aimed to assess the risk of skin cancer in patients taking the ciclosporin who had been exposed to psoralen and ultraviolet-A light (PUVA) and other treatments for severe psoriasis. METHODS We did a nested cohort crossover study of 28 participants in the PUVA follow-up study who were on ciclosporin to compare the frequency of squamous-cell carcinoma before and after first use of ciclosporin. We also analysed the entire PUVA study cohort (1380) to assess the relation between use of this drug and frequency of squamous-cell carcinoma. FINDINGS In the 5 years before first use, six of 28 (21%) ciclosporin users developed a total of 20 squamous cell cancers. After ciclosporin use (average follow-up 6 years), 13 (46%) developed a total of 169 squamous-cell carcinomas. In the nested cohort, after adjustment for amount of exposure to PUVA and methotrexate, incidence of tumours was seven times higher after first ciclosporin use than in the previous 5 years (incidence rate ratio 6.9 [95% CI 4.3-11]). Multivariate analysis of the entire cohort showed that risk of squamous-cell carcinoma after any use of ciclosporin is close to that recorded for at least 200 PUVA treatments (3.1 [2.6-3.7] and 2.8 [2.6-3.2], respectively). INTERPRETATION The risk of squamous cell cancer of the skin is increased by ciclosporin in patients with psoriasis who have been exposed to PUVA. Such risks should be balanced against the effectiveness of the drug and possible newer immunosuppressive agents.

Abstract
The use of combination oral therapies in the management of severe psoriasis is gaining increasing acceptance. We report the concurrent use of mycophenolate mofetil (MMF) (maximum dose 3.0 g daily) with low-dose cyclosporin (mean dose 2.5 mg/kg/day) in nine patients with severe psoriasis. All had previously failed on other systemic therapies. They were all initially on treatment with cyclosporin alone which had either failed to clear their psoriasis or they were unable to tolerate higher doses. After the addition of MMF there was good clinical improvement in three patients and moderate disease control in a further four patients after a follow-up period of 3-11 months, with no additional evidence of toxicity at the doses used. We believe that MMF may be useful in some psoriatic patients unresponsive to or intolerant of other treatments or who are at risk of developing nephrotoxicity at higher doses of cyclosporin.

Abstract
Severe cases of psoriasis and psoriasis arthritis require systemic treatment. Although a number of established drugs are in clinical use, there is a need for new compounds with an improved risk-benefit ratio with a major emphasis on long-term safety. Furthermore, patients with moderate psoriasis ask for systemic drugs to make therapy easier and to avoid excessive local treatments. This article aims to give a brief overview about new drugs or groups of compounds together with an evaluation of their present status in the treatment of psoriasis and their future role with particular respect to efficacy, tolerability, safety and usability.

Abstract
Cytotoxic and immunosuppressive drugs are regularly used to treat proliferative, immunologically mediated inflammatory disorders and some neoplastic diseases of the skin. Methotrexate, azathioprine, mycophenolate mofetil, cyclosporin cyclophosphamide, chlorambucil, and other related drugs have potential benefits in the treatment of severe and/or recalcitrant rheumatic skin diseases. The therapeutic window for these agents is narrow. The major uses of these drugs are for life-threatening cutaneous disorders or as steroid-sparing agents.
