BACKGROUND: Generalized discoid lupus erythematosus (DLE) is an autoimmune skin disease variant rarely reported in dogs. The antimalarial immunomodulator hydroxychloroquine has been suggested as maintenance therapy for generalized DLE in one dog, but several recurrences were noted in the 1 year follow-up of that patient. HYPOTHESIS/OBJECTIVE: To describe the effective treatment of generalized DLE with ciclosporin in one dog. ANIMAL: A 6-year-old, castrated male crossbred dog was presented with pruritic, well-demarcated annular to polycyclic, hyperpigmented plaques with marginal erythema on the dorsal head, neck, trunk and medial extremities; these had been nonresponsive to treatment with doxycycline and niacinamide...

Ciclosporin is a lipophilic cyclic polypeptide with powerful immunosuppressive and immunomodulatory properties that has been used in veterinary medicine for two decades. It is a calcineurin inhibitor whose principal mode of action is to inhibit T cell activation. The drug is principally absorbed from the small intestine and is metabolised in the intestine and liver by the cytochrome P450 enzyme system. Ciclosporin is known to interact with a wide range of pharmacological agents. Numerous studies have demonstrated good efficacy for the management of canine atopic dermatitis and this has been a licensed indication since 2003...

Ciclosporin (Atopica; Novartis Animal Health) has been licensed for canine atopic dermatitis (AD) since 2002. Adverse events (AEs) have been reported in 55 per cent of 759 dogs in 15 clinical trials, but are rare in pharmacovigilance data (71.81 AEs/million capsules sold). Gastrointestinal reactions were most common, but were mild and rarely required intervention. Other AEs were rare (≤1 per cent in clinical trials; <10/million capsules sold). Hirsutism, gingival hyperplasia and hyperplastic dermatitis were rarely significant and resolved on dose reduction...

Ciclosporin A (CsA) has potent immunosuppressive and immunomodulatory activity that has been exploited in human medicine to prevent the rejection of transplanted organs and to manage atopic dermatitis and psoriasis. Over the past decade, CsA has been employed more frequently in veterinary dermatology and its value in the management of several canine and feline dermatoses is now well established. CsA inhibits calcineurin phosphatase, suppressing T cell activation and the synthesis of T cell cytokines consequently impairing the activity of B cells, antigen-presenting cells, mast cells, basophils and eosinophils...

Toll-like receptor (TLR) 2 dependent pathways have an important role in the antimicrobial defense of human keratinocytes, and various factors and compounds have been shown to affect those pathways. Investigating Toll-like receptor function in canine keratinocytes and the potential for their modulation is of similar relevance in dogs due to the frequency of staphylococcal skin infections in this species, particularly in the context of canine atopic dermatitis. This pilot study hypothesized that ciclosporin would have a modulatory effect on the cytokine and TLR mRNA expression of canine progenitor epidermal keratinocytes in response to TLR2 agonists...

The aim of this study was to assess the effects of a standard therapeutic protocol of prednisolone (Pred) on glucose homeostasis in atopic dogs and compare it with previously published data for ciclosporin A (CsA). The central aim of the study was to assess and compare the effects of standard therapeutic protocols of prednisolone (Pred) and ciclosporin A (CsA) on glucose homeostasis in dogs with atopic dermatitis (CAD). Both treatments significantly reduced the physical signs of CAD, as determined by the canine atopic dermatitis extent and severity index version 3 (CADESI-03) and the Edinburgh Pruritus Scale (EPS)...

Canine idiopathic sebaceous adenitis (ISA) is an inflammatory reaction of sebaceous glands, potentially resulting in their complete loss. It is considered a T-cell-mediated disease, but its precise pathogenesis is still unknown. Topical treatment with oil soaks, humectants and shampoos is effective but laborious. Ciclosporin A (CsA), an immunomodulatory drug, has recently been shown to ameliorate the clinical picture of ISA and to reduce inflammation greatly. It is, however, an expensive treatment option. The objective of this multicentre, partly double-blinded, randomized controlled study was to evaluate the efficacy of ciclosporin A, either alone or with topical therapy, in comparison to conventional topical treatment alone, as measured by the primary end-points alopecia and scaling, and multiple histopathological secondary objectives...

Atopic dermatitis (AD) is a common chronic relapsing pruritic skin disease of dogs for which treatment has varied over time and geographical location. Recent high quality randomized controlled trials and systematic reviews have established which drugs are likely to offer consistent benefit. The International Task Force for Canine AD currently recommends a multi-faceted approach to treat dogs with AD. Acute flares should be treated with a combination of nonirritating baths and topical glucocorticoids, once an attempt has been made to identify and remove the suspected causes of the flare...

Six German shorthaired pointer dogs (two females, four males) with exfoliative cutaneous lupus erythematosus (ECLE) were studied in a controlled setting until disease progression necessitated euthanasia. During investigations into the heredity of disease, five dogs received immunomodulatory drugs to alleviate clinical signs (lameness, erythema, scaling, erosions/ulcers). One dog served as a control and received only baths and oral fatty acids. Four dogs received ciclosporin (5-10 mg/kg once daily) for 4.5 months to 2 years...

German Shepherd Dogs have an increased incidence of anal furunculosis (AF), which is a disease characterised by inflammation and ulceration of the perianal tissues. Ciclosporin, an immunosuppressive drug, has been successfully used to treat AF, suggesting that the pathogenesis of disease is likely to have an immune-mediated component. Previous research has shown that the cytokine mRNA profile in AF lesions is consistent with T cell-mediated inflammation. The aims of the current study were to quantify IL-2 and IFNgamma mRNA expression in AF biopsies taken before and after treatment with ciclosporin and to compare cytokine expression with lesion severity...

Limiting dilution analysis showed that the frequency of precursor donor-lytic cytolytic lymphocytes increased dramatically within the leucocyte population recovered by broncho-alveolar lavage in dogs after unilateral lung transplantation. The increases for animals experiencing acute pulmonary rejection (11.5-24.8 times pre-operative level) and for those receiving long-term ciclosporin A therapy (5.4-17.6 times pre-operative level) were similar. Therefore, it appears that ciclosporin A does not prevent the sequestration of precursor donor-lytic cytotoxic cells within lung allograft tissue...
