Treatment of extensive chronic cutaneous graft-versus-host disease in an infant with topical pimecrolimus

Chronic graft-versus-host disease. Part II: Disease activity grading and therapeutic management

Chronic graft-versus-host disease (cGVHD) is a major complication of allogeneic hematopoietic cell transplantation and a leading cause of long-term morbidity, nonrelapse mortality, and impaired health-related quality of life. The skin is commonly affected and presents heterogeneously, making the role of dermatologists critical in both diagnosis and treatment. In addition, new clinical classification and grading schemes inform treatment algorithms, which now include 3 Federal Drug Administration-approved therapies, and evolving transplant techniques are changing disease epidemiology. Part I reviews the epidemiology, pathogenesis, clinical manifestations, and diagnosis of cGVHD. Part II discusses disease grading and therapeutic management.

Management of Chronic Graft-vs.-Host Disease in Children and Adolescents With ALL: Present Status and Model for a Personalised Management Plan

Herein we review current practice regarding the management of chronic graft-vs.-host disease (cGvHD) in paediatric patients after allogeneic haematopoietic stem cell transplantation (HSCT) for acute lymphoblastic leukaemia (ALL). Topics covered include: (i) the epidemiology of cGvHD; (ii) an overview of advances in our understanding cGvHD pathogenesis; (iii) current knowledge regarding risk factors for cGvHD and prevention strategies complemented by biomarkers; (iii) the paediatric aspects of the 2014 National Institutes for Health-defined diagnosis and grading of cGvHD; and (iv) current options for cGvHD treatment. We cover topical therapy and newly approved tyrosine kinase inhibitors, emphasising the use of immunomodulatory approaches in the context of the delicate counterbalance between immunosuppression and immune reconstitution as well as risks of relapse and infectious complications. We examine real-world approaches of response assessment and tapering schedules of treatment. Furthermore, we report on the optimal timepoints for therapeutic interventions and changes in relation to immune reconstitution and risk of relapse/infection. Additionally, we review the different options for anti-infectious prophylaxis. Finally, we put forth a theory of a holistic view of paediatric cGvHD and its associated manifestations and propose a checklist for individualised risk evaluation with aggregated considerations including site-specific cGvHD evaluation with attention to each individual's GvHD history, previous medical history, comorbidities, and personal tolerance and psychosocial circumstances. To complement this checklist, we present a treatment algorithm using representative patients to inform the personalised management plans for patients with cGvHD after HSCT for ALL who are at high risk of relapse.

Cutaneous manifestations of acute and chronic graft-versus-host disease

Graft-versus-host disease (GvHD) is a commonly occurring immunological reaction and frequent complication following allogeneic hematopoietic stem cell transplantation. Its highly diverse manifestations including skin involvement as the most common appearance of GvHD, can dramatically influence patient's quality of life, in particular in the chronic stage, in addition to patient's decreased survival outcome. Hence, the role of the dermatologist has become very crucial in an interdisciplinary setting, particularly since appearances of GvHD in the skin can be multifaceted and challenging. Clinical manifestation of the acute GvHD (aGvHD) is limited to erythematous maculopapular rash and oral mucosal lesions while the chronic form manifests in a wider range in a localized area or disseminated including involvement of nail, scalp and genital area. This article aims to provide a comprehensive overview on the variable cutaneous presentations of acute and chronic GvHD for a proper and early diagnosis on the one hand, and to discuss updated therapeutic options for both acute and chronic GvHD on the other hand, to initiate an adequate treatment to obtain the most beneficial clinical outcome.

Review of Graft-Versus-Host Disease

Graft-versus-host disease (GVHD) is an adverse immunologic phenomenon following allogenic hematopoietic stem cell transplant. Cutaneous manifestations are the earliest and most common presentation of the disease. This article describes the pathophysiology, clinical presentation, diagnosis, and treatment options available for acute and chronic GVHD. Acute and chronic GVHD result from an initial insult triggering an exaggerated inflammatory cascade. Clinical presentation for cutaneous acute GVHD is limited to maculopapular rash and oral mucosal lesions, whereas chronic GVHD can also include nail, scalp, and genitalia changes. Diagnosis is often made clinically and supported by biopsy, laboratory and radiology findings.

Cutaneous Graft-Versus-Host Disease: Diagnosis and Treatment

Graft-versus-host disease (GVHD) is an immunological reaction and a frequent complication following allogeneic hematopoietic stem cell transplantation. It is associated with high mortality rates and may have a significant negative impact on the patient's quality of life, particularly in the chronic-stage setting. Many different organs can be involved, which leads to a wide range of clinical manifestations. In this context, dermatologists play a key role by diagnosing and treating GVHD from the outset since cutaneous features are not just the most common but are also usually the presenting sign. Several skin-direct therapies are available and may be indicated as monotherapy or adjuvant treatment in order to allow faster tapering and withdrawal of systemic immunosuppression. Treatment of steroid-refractory patients remains a challenge and, to date, no consensus has been reached for one single agent in second-line therapy. This article aims to review skin involvement as well as provide and update discussion on therapeutic options for both acute and chronic cutaneous GVHD.

National Institutes of Health Consensus Development Project on Criteria for Clinical Trials in Chronic Graft-versus-Host Disease: V. The 2014 Ancillary Therapy and Supportive Care Working Group Report

The 2006 National Institutes of Health (NIH) Consensus paper presented recommendations by the Ancillary Therapy and Supportive Care Working Group to support clinical research trials in chronic graft-versus-host disease (GVHD). Topics covered in that inaugural effort included the prevention and management of infections and common complications of chronic GVHD, as well as recommendations for patient education and appropriate follow-up. Given the new literature that has emerged during the past 8 years, we made further organ-specific refinements to these guidelines. Minimum frequencies are suggested for monitoring key parameters relevant to chronic GVHD during systemic immunosuppressive therapy and, thereafter, referral to existing late effects consensus guidelines is advised. Using the framework of the prior consensus, the 2014 NIH recommendations are organized by organ or other relevant systems and graded according to the strength and quality of supporting evidence.

Consensus conference on clinical practice in chronic graft-versus-host disease (GVHD): first-line and topical treatment of chronic GVHD

Chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation is still associated with significant morbidity and mortality. First-line treatment of cGVHD is based on steroids of 1 mg/kg/day of prednisone. The role of calcineurin inhibitors remains controversial, especially in patients with low risk for mortality (normal platelets counts), whereas patients with low platelets at diagnosis and/or high risk for steroid toxicity may be treated upfront with the combination of prednisone and a calcineurin inhibitor. Additional systemic immunosuppressive agents, like thalidomide, mycophenolic acid, and azathioprine, failed to improve treatment results in the primary treatment of cGVHD and are in part associated with higher morbidity, and in the case of azathioprine, with higher mortality. Despite advances in diagnosis of cGVHD as well as supportive care, half of the patients fail to achieve a long-lasting response to first-line treatment, and infectious morbidity continues to be significant. Therefore, immunomodulatory interventions with low infectious morbidity and mortality such as photopheresis need urgent evaluation in clinical trials. Beside systemic immunosuppression, the use of topical immunosuppressive interventions may improve local response rates and may be used as the only treatment in mild localized organ manifestations of cGVHD.

Use of pimecrolimus cream in disorders other than atopic dermatitis

BACKGROUND

Pimecrolimus is indicated for treatment of atopic dermatitis and has been evaluated in many other disorders.

OBJECTIVE

To review the efficacy of pimecrolimus in treatment of disorders other than atopic dermatitis.

METHODS

We performed a PubMed search of the English-language literature using the key word "pimecrolimus." We reviewed articles reporting the use of pimecrolimus in disorders other than atopic dermatitis and classified them by the type of study used to evaluate efficacy.

RESULTS

Randomized, double-blind studies have shown that pimecrolimus is superior to vehicle in treatment of seborrheic dermatitis, hand dermatitis, and asteatotic eczema but have yielded conflicting results regarding intertriginous psoriasis and vitiligo. Open-label studies involving four or more patients have shown favorable results in many disorders, including contact dermatitis, rosacea, lichen sclerosus, and oral and genital lichen planus. Case reports have shown that topical pimecrolimus may be useful in cutaneous graft-versus-host disease, lichen striatus, cutaneous lichen planus, and many other disorders.

CONCLUSIONS

Topical pimecrolimus appears to be an effective treatment for many disorders other than atopic dermatitis, especially seborrheic dermatitis, hand dermatitis, and asteatoic eczema. It may be effective in many other disorders, but its role in these disorders remains to be clarified by additional studies.

The role of topical calcineurin inhibitors for skin diseases other than atopic dermatitis

The topical calcineurin inhibitors (TCIs) pimecrolimus and tacrolimus are approved for atopic dermatitis but have additional potential in other inflammatory skin diseases. This article reviews their clinical use in non-atopic dermatitis diseases. In seborrheic dermatitis, asteatotic eczema, and contact dermatitis, TCIs are of great benefit and can compete with topical corticosteroids. In psoriasis, TCIs have shown clinical efficacy and safety in facial and intertriginous lesions. Further investigations into possible combinations of TCIs with other established treatments such as UVB irradiation in this disorder are necessary. Initial studies in cutaneous lupus erythematosus have been promising, whereas the response in rosacea and rosacea-like eruptions has been mixed. TCIs have been associated with good clinical responses in oral lichen planus and anogenital lichen sclerosus et atrophicus. In vitiligo, TCIs are associated with some degree of repigmentation, with better results being seen in children and in facial and neck areas. TCIs have a synergistic effect with UVB irradiation in vitiligo. There is a long list of small series and case reports documenting use of TCIs in various other skin conditions that warrant further validation. Although the established mode of action of TCIs is T-cell control, other effects also need to be considered. Specifically, TCIs reduce pruritus and erythema, which cannot be explained by T-cell interactions, and further investigations are needed in these fields.

Ancillary therapy and supportive care of chronic graft-versus-host disease: national institutes of health consensus development project on criteria for clinical trials in chronic Graft-versus-host disease: V. Ancillary Therapy and Supportive Care Working Group Report

The Ancillary Therapy and Supportive Care Working Group had 3 goals: (1) to establish guidelines for ancillary therapy and supportive care in chronic graft-versus-host disease (GVHD), including treatment for symptoms and recommendations for patient education, preventive measures, and appropriate follow-up; (2) to provide guidelines for the prevention and management of infections and other common complications of treatment for chronic GVHD; and (3) to highlight the areas with the greatest need for clinical research. The definition of "ancillary therapy and supportive care" embraces the most frequent immunosuppressive or anti-inflammatory interventions used with topical intent and any other interventions directed at organ-specific control of symptoms or complications resulting from GVHD and its therapy. Also included in the definition are educational, preventive, and psychosocial interventions with this same objective. Recommendations are organized according to the strength and quality of evidence supporting them and cover the most commonly involved organs, including the skin, mouth, female genital tract, eyes, gastrointestinal tract, and lungs. Recommendations are provided for prevention of infections, osteoporosis, and steroid myopathy and management of neurocognitive and psychosocial adverse effects related to chronic GVHD. Optimal care of patients with chronic GVHD often requires a multidisciplinary approach.

Topical pimecrolimus for skin disease other than atopic dermatitis

Pimecrolimus is an ascomycin macrolactam. It is a specific calcineurin inhibitor that allows topical application. The highly lipophilic nature of this compound reduces the risk of systemic absorption through normal and inflammed skin. Pimecrolimus shows activity not only against T-cell activation, but also against mast cells and pruritus. Pimecrolimus 1% cream is approved for atopic dermatitis, and also has a great potential in other inflammatory skin diseases. Clinical trials have been performed in contact- and seborrhoeic dermatitis, genital lichen sclerosus, intertriginous psoriasis and cutaneous lupus erythematosus. In other diseases, the available data are limited to small case series, or individual cases of graft-versus-host disease or Netherton's disease. Although the use of calcineurin inhibitors in the treatment of vitiligo is promising, detailed studies with pimecrolimus and ultraviolet-irradiation are necessary and there is a need for prospective randomised, double-blind controlled trials.

Pimecrolimus in dermatology: atopic dermatitis and beyond

Pimecrolimus is a calcineurin inhibitor developed for the topical therapy of inflammatory skin diseases, particularly atopic dermatitis (AD). Pimecrolimus selectively targets T cells and mast cells. Pimecrolimus inhibits T-cell proliferation, as well as production and release of interleukin-2 (IL-2), IL-4, interferon-gamma and tumour necrosis factor-alpha. Moreover, pimecrolimus inhibits mast cell degranulation. In contrast to tacrolimus, pimecrolimus has no effects on the differentiation, maturation and functions of dendritic cells. In contrast to corticosteroids, pimecrolimus does not affect endothelial cells and fibroblasts and does not induce skin atrophy. Given the low capacity of pimecrolimus to permeate through the skin, it has a very low risk of systemic exposure and subsequent systemic side-effects. In different randomised controlled trials, topical pimecrolimus as cream 1% (Elidel) has been shown to be effective, well tolerated and safe in both adults and children with mild to moderate AD. In addition, pimecrolimus has been successfully used in inflammatory skin diseases other than AD, including seborrheic dermatitis, intertriginous psoriasis, lichen planus and cutaneous lupus erythematosus.
