Abstract
Isolated human amniotic cells (hAC) could be used as a source of immunomodulatory factors in regenerative medicine and transplantation. However, in previous experimental studies, native hAC administered to skin graft recipients did not induce graft immunotolerance. To strengthen the immunomodulatory properties of hAC prior to administration to the recipient, we activated them ex vivo using pro-inflammatory cytokines. In this study, we compared the transplantation efficiency of skin allografts (mouse to mouse) and xnografts (rat to mouse) in recipient mice divided into three main groups receiving: 1. Placebo (control group); 2. Cyclosporine A (CsA) [10 or 50 mg/kg body weight (bw)]; 3. suspension of hAC activated ex vivo by IL-1β and INFγ, administered into a tail vein or subcutaneously. During 15 days of observation, hAC administered intravenously or subcutaneously after allotransplantation appeared to be as safe and efficient as CsA at the dose of 10 mg/kg bw in preventing rejection of skin allo- and xenografts. After xenotransplantation, however, only hAC administered intravenously prevented rejection to an extent comparable to CsA. Both CsA (10 mg/kg bw) and activated hAC reduced inflammatory infiltration in the skin (after intravenous injection) and did not increase the concentration of the inflammation marker SAP in serum or percentage of leukocytes in blood. Finally, we concluded that administration of activated hAC is safe and efficient in the presented animal model of skin allo- and xenotransplantation in a route-dependent manner. Activated hAC injected intravenously exhibit an immunosuppressive effect comparable to CsA administered at the dose of 10 mg/kg bw in both allo- and xenotransplantation.

Abstract
Erythrodermic psoriasis (EP) is a rare variant of psoriasis, which is potentially life threatening and often resistant to conventional therapy. Biologics have revolutionized the treatment of plaque-type psoriasis, and shown promise in EP. However, due to the lack of head-to-head studies and the rarity of EP, no high level evidence-based treatment guidelines for EP have been established, and the evidence of treatment of EP is limited to case reports or small case series. Here, we present a narrative review focusing on the up-to-date information for the treatment of EP.

Abstract
BACKGROUND Psoriasis is a genetically predisposed autoimmune disease mediated by cytokines released by the activated immune cells. It manifests inflammatory, scaly red or white silvery flaky skin which may be a fluid-filled lesion with soreness and itchiness. The prevalence rate of psoriasis is increasing day by day. Despite having such a high prevalence rate, the treatment of psoriasis is still limited. Hence, there is a need to rethink the various treatment strategies available in the allopathic as well as in the alternative systems of medicine. METHODS Various bibliographic databases of previously published peer-reviewed research papers were explored and systematic data culminated in terms of various treatment strategies used for the management of psoriasis. The prime focus is given towards modern as well as alternative systems of medicine such as phototherapy, a combination of phototherapy with pharmacotherapy such as Ayurveda, Yoga and naturopathy, Unani, Siddha, and Homeopathy to treat psoriasis. RESULTS A comprehensive review of 161 papers, including both research and review articles, was carried out to make the article readily understandable. The pathogenesis including inflammatory mediators and type of psoriasis is discussed before the treatment strategies to understand the pathophysiology of the disease. The uniqueness, procedure, advantages, and limitations of conventional, advanced, and traditional systems of medicine to treat psoriasis are discussed in detail. Emphasis has also been given towards marine sources such as fish oil, marine sponges, and algae. CONCLUSION Although there are many modern and alternative treatment strategies available to treat psoriasis, none of them have been proven to provide complete relief to patients. Moreover, they are associated with certain side effects. In order to overcome them, novel drug delivery systems have been utilized and found effective; however, their stability and safety become the major impediments towards their successful positioning. Traditional and alternative treatment strategies have found to be safe and effective but their use is localized to certain areas. In a nutshell, to achieve successful treatment of psoriasis, there is a need to focus on the development of stable and non-toxic novel drug delivery systems or the promotion of traditional systems to treat psoriasis.

Abstract
BACKGROUND AND OBJECTIVE Psoriasis is an autoimmune skin disease involving cascading release of cytokines activated by the innate and acquired immune system. The increasing prevalence rate of psoriasis demands for more appropriate therapy. The existing chemical moiety is promising for better therapeutic outcome, but the selection of a proper channel for administration has to be reviewed. Hence there is a need to select the most appropriate dosage form and route of administration for improving the curative rate of psoriasis. RESULTS A total of 108 systematic reviews of research and review articles were conducted to make the manuscript comprehensible. The role of inflammatory mediators in the pathogenesis of the disease is discussed for a better understanding of the selection of pharmacotherapy. The older and newer therapeutic moiety with its mode of administration for psoriasis treatment has been discussed. With a comparative review on topical and oral administration of first-line drugs such as methotrexate (MTX), cyclosporine (CsA), and betamethasone, its benefits-liabilities in the selected routes were accounted for. Emphasis has also been paid on advanced nanocarriers for dermatologic applications. CONCLUSION For a better therapeutic outcome, proper selection of drug moiety with its appropriate administration is the major requisite. With the advent of nanotechnology, the development of nanocarrier for dermatologic application has been successfully demonstrated in positioning the systemically administrated drug into topical targeted delivery. In a nutshell, to achieve successful treatment strategies towards psoriasis, there is a need to focus on the development of stable, non-toxic nanocarrier for topical delivery. Inclusion of the existing orally administered drug moiety into nanocarriers for topical delivery is proposed in order to enhance therapeutics payload with reduced side effects which serves as a better treatment approach for relief of the psoriasis condition.

Abstract
OBJECTIVE Atopic dermatitis (AD) is a common, chronic, inflammatory skin disease that can significantly reduce the quality of life of not only patients but also entire families. This review will focus on the currently available non-pharmacologic and pharmacologic treatments for the control and management of AD. RESEARCH DESIGN AND METHODS A review of English-language articles from January 1953 to May 2006 was performed within the MEDLINE database. Search terms included, but were not limited to, atopic dermatitis, topical corticosteroids, and topical calcineurin inhibitors. Studies evaluating the diagnosis, physical and psychological burden, and underlying pathophysiology of AD were included. Particular focus was placed on literature presenting key safety and efficacy data from clinical trials involving AD treatment. RESULTS Although good skin care and trigger avoidance are fundamental to AD management, most patients also require pharmacologic intervention. Topical therapies comprise the foundation of AD treatment. In particular, topical corticosteroids have been a mainstay in AD treatment for several decades and the newer topical calcineurin inhibitors have become a valuable addition to the therapeutic armamentarium. TCIs are a safe and effective AD treatment; they limit the number of disease flares, extend the time between flares, and provide a steroid-sparing option that may be of particular benefit in the pediatric population. The use of more potent therapies, such as systemic (oral/injected) agents or phototherapy, is typically limited to the treatment of severe, refractory disease. Additionally, owing to the increased risk for bacterial, viral, and fungal infections in patients with AD, topical or systemic antimicrobials are an important component of treatment. LIMITATIONS Case reports and small-scale studies were typically not included in this analysis and owing to the limited number of trials evaluating TCSs, consensus statements and comprehensive review articles were used to obtain information pertaining to the use of this treatment in AD. CONCLUSIONS AD is a common, chronic disease requiring a long-term management strategy that incorporates preventive measures and a multipronged treatment approach.

Abstract
Well-designed studies that help guide physicians to apply the optimal therapeutic strategy for the management of pyoderma gangrenosum are lacking in the literature. A multidisciplinary approach is paramount for the effective management of this condition, with close involvement of a wound-care specialist and a microbiologist. Treatment should be stepwise in nature. Local wound care, avoidance of trauma and the application of local steroid or tacrolimus ointment are the first-line treatments. Steroid therapy is the most widely published effective therapy for achieving resolution of pyoderma gangrenosum, although there is growing evidence for the efficacy of infliximab in refractory cases. Other therapies such as dapsone and clofazamine should be left as third-line agents for refractory pyoderma gangrenosum, while novel treatments such as granulocyte apheresis should only be used under trial conditions, to gain an objective evaluation of their efficacy. This article reviews the published treatment strategies in current use, and aims to guide the effective management of pyoderma gangrenosum.

Abstract
OBJECTIVE To evaluate the efficacy of cyclosporin in controlling the clinical signs associated with atopic dermatitis in dogs under Australian field conditions. DESIGN A multicentre prospective clinical investigation of the use of cyclosporin in 41 dogs with atopic dermatitis. PROCEDURE Dogs were treated with cyclosporin (5 mg/kg orally once daily with food) for 6 weeks. Four clinical parameters of severity of atopic dermatitis were measured on Day 0 and on Day 42 using a 0 to 4 scoring system. Individual variables were then combined to form a Global Score. Both client and clinician observed pruritus scores were combined to form a Pruritus Score. Pre- and post-treatment scores were statistically analysed. The difference in results between the two investigators was also recorded and analysed. RESULTS All dogs showed a marked reduction in pruritus and erythema during the 6-week treatment period. All dogs showed a significant (P < 0.001) improvement in clinical lesion scores and Global Score (P < 0.001). The mean percentage improvement in Global Score from Day 0 to Day 42 was 83.9%. The mean percentage improvement in Pruritus Score from Day 0 to Day 42 was 83%. The medication was well tolerated. Side effects such as vomiting, diarrhoea and soft stools were observed in four dogs. Another four dogs developed bacterial pyoderma during the trial period. There was no significant difference in results between the two centres. CONCLUSION Cyclosporin was well tolerated and efficacious in the symptomatic treatment of atopic dermatitis in dogs attending two veterinary dermatology referral centres in Australia, under Australian field conditions, when administered at 5 mg/kg/day for 6 weeks.

Abstract
BACKGROUND Epidermolysis bullosa acquisita (EBA) is a rare antibody-mediated autoimmune blistering disease of adults. Likewise, acquired factor VIII deficiency is a rare antibody-mediated disease of adulthood. Both diseases can be exceedingly difficult to treat and refractory to immunomodulatory therapies. METHODS Herein, we report a challenging case of EBA and acquired factor VIII deficiency in the same patient. RESULTS Cyclosporine 4 mg/kg/day rapidly controlled both disease processes after the patient failed to respond to prednisone, colchicine, and pulse cyclophosphamide. The EBA relapsed when the cyclosporine was decreased to 2 mg/kg/day and the patient wore snuggly fitting new shoes, but it cleared quickly when the dose was increased. Cyclosporine has since been decreased gradually to 1.5 mg/kg/day without relapse of either condition or detectable side-effects. CONCLUSIONS Cyclosporine should be considered when EBA and/or acquired factor VIII deficiency fail to respond to conservative therapy. Both conditions usually respond rapidly to cyclosporine 4-6 mg/kg/day.

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
Dermatologists use a variety of systemic drugs, some of which can cause severe adverse reactions and even fatalities. Ivermectin, a well-tolerated drug, can cause severe neurological side effects, whereas metronidazole, in high cumulative doses, has been associated with convulsions and rarely with hepatotoxicity. Dapsone is associated with frequent hematologic side effects, such as methemoglobinemia, hemolysis, and anemia. Although hepatotoxicity is rare and usually mild and reversible with the new antifungal agents, severe cutaneous reactions (such as toxic epidermal necrolysis, Stevens-Johnson syndrome, and anaphylaxis) have been reported. Even a relatively safe drug such as acyclovir has been reported to be the cause of renal failure and neurotoxicity. Retinoids can cause not so benign "benign" intracranial hypertension. Methotrexate can cause not only liver toxicity, but also myelosuppression and pancytopenia, which may be acute and life threatening. Nephrotoxicity is a well-recognized side effect of cyclosporine, whereas thrombotic thrombocytopenic purpura, which is associated with high morbidity and mortality, is less well known. Dermatologists should be familiar with these and other severe adverse reactions of the most popular and most used systemic medications of our trade.

Abstract
BACKGROUND An intermittent short course of cyclosporin A (CyA) therapy is a good choice in the treatment of severe psoriasis. Nevertheless, some severe or resistant patients might benefit from long-term treatment. Adverse effects of long-term use of CyA are investigated and the results are compared with the literature. PATIENTS AND METHODS A retrospective study of adverse effects of CyA treatment in a group of 53 patients suffering from psoriasis. The mean treatment time was 31.4 +/- 23.2 months with a minimum of 4 months to a maximum of 95 months, with very few short interruptions of treatment (from 2 to 5 months in five patients). RESULTS The group consisted of 29 women and 24 men, ranging in age from 18 to 65 years, with an average age of 44.49 years. Arterial hypertension appeared in 45.3% of patients during treatment. Pharmacological treatment was required in 32% of these patients to control the condition. Serum creatinine levels were transiently elevated in 11.3% of the cases, but withdrawal of treatment was required in none of them. DISCUSSION Long-term CyA treatment might be necessary in some patients and this study shows that it could be sustained with a close follow-up. This involves regular visits depending on each patient, as well as common test protocol and clinical evaluation. In conclusion, this retrospective study seems to confirm the relative safety of long-term CyA treatment when patients are adequately monitored.

Abstract
Cyclosporine is being increasingly used in veterinary medicine. Oral formulations of the drug have found many therapeutic uses, but topical formulations have met with only limited success, probably owing to their poor penetration through the stratum corneum. The concurrent use of ketoconazole to inhibit cyclosporine metabolism has been shown to reduce the required dose and hence the cost of cyclosporine therapy. In human medicine, adverse reactions to the drug, especially nephrotoxicity, are common but in dogs given the commonly used oral dose of 5 mg/kg per day there have been few adverse reactions. However, no toxicity studies lasting longer than 12 months have been carried out in this species. This paper reviews the pharmacokinetics, drug and procedural interactions, contraindications and the adverse reactions to cyclosporine, with particular reference to its use in the treatment of dermatological conditions in dogs, cats and people.

Abstract
BACKGROUND Alefacept, human LFA-3/IgG1 fusion protein, is a novel biological agent currently being developed for the treatment of chronic plaque psoriasis. Alefacept selectively reduces the memory-effector T cells that have been implicated in the pathogenesis of the disease; as a result, alefacept is classified as a therapy that induces remission (so-called 'remittive' therapy). In a previously published randomized, placebo-controlled phase II study of intravenous alefacept in 229 patients with chronic plaque psoriasis, clinical improvement was observed during dosing as well as in the postdosing follow-up period. OBJECTIVES To assess the remission period following alefacept therapy. METHODS The time before re-treatment was required was measured in patients who were 'clear' or 'almost clear' of disease according to a physician global assessment at the end of the follow-up phase. RESULTS In these patients, responses were sustained for a median of 10 months, and for up to 18 months. No patient reported disease rebound after cessation of alefacept. CONCLUSIONS Alefacept is a biological agent for the treatment of chronic plaque psoriasis that provides disease-free intervals and time off drug therapy.

Abstract
BACKGROUND Psoriasis is a chronic, relapsing skin disease that may require multiple treatment courses. Alefacept targets the memory T cells implicated in psoriasis pathogenesis. This open-label study evaluated the safety and tolerability, efficacy, and pharmacodynamics of repeat courses of alefacept in men and women with chronic plaque psoriasis. This article reports the interim results of this ongoing study. METHODS Patients (n = 174) who participated in previous phase II studies of alefacept were included in this retreatment study. Intravenous alefacept (7.5 mg) was administered once weekly for 12 weeks followed by 12 weeks of observation. Initial and subsequent retreatment courses were only given when, in the opinion of the investigators, disease had returned and necessitated treatment; CD4+ T-cell counts had to be at or above the lower limit of normal. RESULTS Adverse events were similar regardless of the retreatment course. No opportunistic infections, rebound of disease, or flares were reported. Low titers of anti-alefacept antibodies occurred in a few patients without related safety issues. Sixty-six per cent of patients achieved a >/= 50% reduction in the Psoriasis Area and Severity Index (PASI) at any time after the first dose of retreatment course 1. Patients who received two retreatment courses (n = 50) had consistent or improved responses after the second course; 64% and 68% of these patients achieved a >/= 50% PASI improvement at any time after the first dose of retreatment courses 1 and 2, respectively. Alefacept selectively reduced memory T cells without cumulative effects. CONCLUSIONS Repeat courses of alefacept were well tolerated, and subsequent retreatment courses were at least as effective as the initial course of therapy.

Abstract
Cyclosporin has been increasingly used for the treatment of skin diseases in small animals. Reported uses include the treatment of atopy, cutaneous lupus erythematosus, feline acquired alopecia resembling pseudopelade of humans, pemphigus erythematosus, pemphigus foliaceus, perianal fistulae and sebaceous adenitis. In addition, cyclosporin has been used anecdotally for several other skin diseases. Few side effects have been noted at doses therapeutic for dermatologic diseases. Current suggestions for monitoring, and the value of trough cyclosporin serum concentrations for prediction of toxicity and efficacy are discussed.

Abstract
UNLABELLED Tacrolimus, a macrolide immunomodulator, is believed to control atopic dermatitis by inhibiting T lymphocyte activation, altering cell surface expression on antigen-presenting dendritic cells and modulating the release of inflammatory mediators from skin mast cells and basophils. Tacrolimus ointment penetrates human skin with no systemic accumulation after repeated applications; systemic absorption is generally low, with most patients in clinical trials having blood concentrations of the drug below the limit of quantification. Moderate to severe atopic dermatitis significantly improved (measured using multiple end-points, including > or = 90% improvement in Physician's Global Evaluation of Clinical Response) with tacrolimus 0.03 and 0.1% ointment compared with vehicle in both adult (n = 304 and 328) and pediatric (n = 351) patients in three 12-week, double-blind, randomized, phase III trials. In adults, tacrolimus ointment was effective therapy for the treatment of atopic dermatitis on all skin regions, including the head and neck. The 0.1% concentration was more effective than the 0.03% concentration. Clinical improvement in moderate to severe atopic dermatitis in adult (n = 316) or pediatric (n = 255) patients was seen as early as week 1, and improvement continued and/or was maintained for up to 6 and/or 12 months in long-term studies. The 0.1% formulation was also effective and well tolerated for up to 2 years. Tacrolimus 0.03 and 0.1% ointment was associated with significant quality-of-life benefit in adults, children (aged 5 to 15 years) and toddlers (aged 2 to 4 years) with atopic dermatitis in 12-week phase III trials (n = 985). Skin burning and pruritus were the most common application site adverse events in adult and pediatric patients in short-term and long-term trials. These events were generally of short duration and mild or moderate severity. Cutaneous infections occurred with a similar incidence after treatment with tacrolimus ointment to that seen after vehicle in short-term trials. CONCLUSION Both short- and long-term monotherapy with tacrolimus 0.03 and 0.1% ointment improves moderate to severe atopic dermatitis in adult and pediatric patients. Topical tacrolimus ointment is well tolerated, with the majority of adverse events being localized, transient in nature and of mild or moderate severity. Tacrolimus ointment provides a promising addition to the currently available treatments for atopic dermatitis; it can be used as a short- or long-term intermittent therapy for moderate to severe disease, including disease on the head or neck, in adult (0.1 and 0.03% formulations) and pediatric (0.03% formulation) patients who are not adequately responsive to or are intolerant of conventional treatments.

Abstract
Cyclosporine A (CsA) has been in clinical use for some decades, primarily for the prevention and treatment of organ transplant rejection and graft-versus-host disease. In more recent years, Cyclosporine has been recognized as beneficial in the treatment of dermatologic diseases, such as: psoriasis, lichen planus, Behcet disease, atopic dermatitis, pyoderma gangrenosum and epidermolysis bullosa acquisita. Above all, Cyclosporine is an important therapeutic modality for several dermatologic diseases that are refractory to other agents.

Abstract
BACKGROUND Commonly used treatments for pyoderma gangrenosum are medical, with immunosuppressive agents employed most often. OBJECTIVE To report a case and discuss the indications for radical surgical treatment of pyoderma gangrenosum. METHODS Analysis of a case of Crohn's disease-associated pyoderma gangrenosum treated with immunosuppression followed by amputation, and a review of the literature on surgical management of pyoderma gangrenosum. RESULTS In unstable patients with intractable multiple medical problems, surgical treatment of pyoderma gangrenosum may be indicated by the existence of these life-threatening comorbidities. The recent literature suggests that surgical management of pyoderma gangrenosum may also be appropriate in other special circumstances. CONCLUSIONS Surgical management, including amputation, may have a role in the management of pyoderma gangrenosum. Further research is needed to delineate precisely the circumstances and patient factors that are appropriate indications for such surgery.

Abstract
AIM To evaluate the effect of cyclosporin treatment on clinical and histological parameters in adult patients with refractory coeliac disease. METHODS Thirteen patients were treated with oral cyclosporin for 2 months, aiming at serum levels of 100-200 ng/mL. Seven extended medication intake up to a maximum of 12 months. Before and after treatment, clinical parameters were monitored and small intestinal biopsies taken. Ten of 13 patients were typed for HLA-DQA1 and -DQB1 alleles. RESULTS Eight of 13 patients responded histologically to cyclosporin treatment. Normalization of villi was demonstrated in five patients, three after prolonged treatment. Eight patients reported a clinical response, of whom six had concomitant histological improvement. No serious side-effects of cyclosporin were noticed. Nine of 10 patients who were immunogenetically typed carried the coeliac disease associated serologic DQ2 markers, one carried neither DQ2 nor DQ8 markers. CONCLUSION In our study group of 13 adult refractory coeliac disease patients, cyclosporin in therapeutic doses induced a histological improvement in eight patients (61%), in five of whom (38%) normalization of villi was demonstrated. Thus, we believe that cyclosporin is a therapeutic option in refractory coeliac disease, although we could not confirm earlier reports of unconditional successful treatment.

Abstract
Azathioprine, cyclophosphamide, methotrexate, and cyclosporine are the immunosuppressive agents most commonly used by dermatologists. Azathioprine has a relatively good safety profile and is therefore often preferred for the treatment of chronic eczematous dermatitides and bullous disorders. Awareness of the role of genetic polymorphisms in its metabolism can increase the efficacy and safety of this drug. Cyclophosphamide is an antimetabolite that has a more rapid onset of immunosuppressive effect than azathioprine, but has significant short-term and long-term toxicity. It is of use in fulminant, life-threatening cutaneous disease. Methotrexate is an antimetabolite that has significant anti-inflammatory activity. Despite its hepatotoxicity, its role in inflammatory dermatoses is broadening. Likewise, the role of cyclosporine is being expanded. This drug has potent T-cell inhibitory effects secondary to interference with intracellular signal transduction. Given the evidence for cumulative renal toxicity, it currently has a role in the short-term treatment of refractory psoriasis and atopic dermatitis, as well as in select inflammatory dermatoses. Familiarity with disease-specific clinical efficacy, side-effect profile, and dosage allows the successful and judicious use of these drugs in dermatologic disorders.

Abstract
Amphiregulin (AR) is a heparin-binding, heparin-inhibited member of the epidermal growth factor (EGF) family and an autocrine growth factor for human keratinocytes. Previous studies have shown that AR expression is increased in psoriatic epidermis. To test the hypothesis that aberrant AR expression is central to the development of psoriatic lesions, we constructed a transgene (K14-ARGE) encoding a human keratin 14 promoter-driven AR gene. Our results indicate that transgene integration and subsequent expression of AR in basal keratinocytes correlated with a psoriasis-like skin phenotype. Afflicted mice demonstrated shortened life spans, prominent scaling and erythematous skin with alopecia, and occasional papillomatous epidermal growths. Histologic examination revealed extensive areas of marked hyperkeratosis with focal parakeratosis, acanthosis, dermal and epidermal lymphocytic and neutrophilic infiltration, and dilated blood vessels within the papillary dermis. Our results reveal that AR exerts activity in the skin that is distinct from that of transgenic transforming growth factor-alpha or other cytokines, and induces skin pathology with striking similarities to psoriasis. Our observations also link the keratinocyte EGF receptor-ligand system to psoriatic inflammation, and suggest that aberrant expression of AR in the epidermis may represent a critical step in the development or propagation of psoriatic lesions.
