Review
Graft-versus-host disease (GVHD) is a major cause of mortality and morbidity following allogeneic hematopoietic stem cell transplantation. Extracorporeal photopheresis (ECP), which exposes mononuclear cells to ultraviolet A irradiation in the presence of a photosensitizing agent, has shown efficacy in the treatment of GVHD. Recent observations in molecular and cell biology have revealed the mechanisms by which ECP can reverse GVHD, including lymphocyte apoptosis, differentiation of dendritic cells from circulating monocytes, and modification of the cytokine profile and T cell subpopulations. Technical innovations have made ECP accessible to a broader range of patients; however, logistical constraints may limit its use. In this review, we scrutinize the development of ECP from its origins to recent insights into the biology underlying ECP efficacy. We also review practical aspects that may complicate successful ECP treatment. Finally, we analyze how these theoretical concepts translate into clinical practice, summarizing the published experiences of leading research groups worldwide.

Review
Patients with steroid-refractory graft-versus-host disease (GvHD) are known to have a poor prognosis and for decades no approved drug has been available to treat this serious condition. Although ruxolitinib, a selective Janus kinase (JAK)1/2 inhibitor demonstrated significantly higher response rates in randomized trials compared to the best available therapy, and thus, is of benefit in both acute as well as chronic GvHD, there is an urgent medical need to improve results, such as durability of responses, response in eye, liver and lung manifestations and reduction of infectious complications. In this "Review" article we would like to offer strategies for improving treatment results in patients with steroid-refractory GvHD by combining ruxolitinib with extracorporeal photopheresis (ECP), a leukapheresis-based immunomodulatory treatment frequently applied in T-cell mediated immune disease including GvHD. Our article explores key published evidence supporting the clinical efficacy of both ruxolitinib and ECP in the treatment of GvHD and highlights their potentially complementary mechanisms of action.

Review
Extracorporeal photopheresis (ECP) is an immunomodulatory therapy that has been used for over 35 years to treat numerous conditions. ECP was initially approved by the US FDA in 1988 for the treatment of Sézary syndrome, a leukemic form of cutaneous T-cell lymphoma (CTCL). Although CTCL remains the only FDA-approved indication, ECP has since been used off-label for numerous other conditions, including graft-versus-host disease (GvHD), systemic sclerosis, autoimmune bullous dermatoses, Crohn's disease, and prevention of solid organ transplant rejection. In Canada, ECP is mainly used to treat CTCL, acute and chronic GvHD, and in some instances systemic sclerosis. Herein, we review the current concepts regarding ECP mechanism of action, treatment considerations and protocols, and efficacy.

Review
Extracorporeal photopheresis (ECP) is an apheresis procedure that is conventionally used as a first-line treatment for cutaneous and leukemic subtypes of T-cell lymphoma, such as Sezary's syndrome and mycosis fungoides. Over the past three decades, its immunotherapeutic properties have been tested on a variety of autoimmune conditions, including many dermatologic diseases. There is ample evidence of ECP's ability to modify leukocytes and alter cytokine production for certain dermatologic diseases that have been refractory to first-line treatments, such as atopic dermatitis. However, the evidence on the efficacy of ECP for the treatment of these dermatologic diseases is unclear and/or lacks sufficient evidence. The purpose of this paper is to review the literature on the utilization and clinical efficacy of ECP in the treatment of several [autoimmune] dermatologic diseases and discuss its applications, guidelines, recommendations, and future implementation for dermatologic diseases.

Review
Haematopoietic stem cell transplantation (HSCT) is the treatment of choice for malignant haematological diseases. Despite continuous improvements in pre- and post-transplantation procedures, the applicability of allo-HSCT is limited by life-threatening complications such as graft-versus-host disease (GvHD), engraftment failure, and opportunistic infections. Extracorporeal photopheresis (ECP) is used to treat steroid resistant GvHD with significant success. However, the molecular mechanisms driving its immunomodulatory action, whilst preserving immune function, require further understanding. As ECP is safe to administer with few significant adverse effects, it has the potential for earlier use in the post-HSCT treatment of GvHD. Thus, further understanding the immunomodulatory mechanisms of ECP action may justify more timely use in clinical practice, as well as identify biomarkers for using ECP as first line or pre-emptive GvHD therapy. This review aims to discuss technical aspects and response to ECP, review ECP as an immunomodulatory treatment modality for chronic GvHD including the effect on regulatory T cells and circulating vs. tissue-resident immune cells and consider the importance of emerging biomarkers for ECP response.

PURPOSE OF REVIEW
Extracorporeal photochemotherapy (photopheresis, ECP) is a cell-based immunomodulatory treatment that separates leukocytes from peripheral blood, exposes them to a photosensitizing agent followed by ultraviolet A light, and then reinfuses them back into the patient. ECP has been found to be effective for graft versus host disease, transplant rejection, and various autoimmune diseases. The mechanism is not well understood but studies have shown clinical benefit in the treatment of systemic sclerosis (SSc). This review examines the ECP technique, advances in our knowledge of its mechanism, and the data supporting its use in SSc-like fibrosing diseases and in SSc itself.
RECENT FINDINGS
Multiple lines of evidence support ECP use in SSc. ECP generates apoptotic cells and dendritic cells, induces production of anti-inflammatory cytokines, and increases regulatory T cell numbers. Clinical studies have generally demonstrated improvement, especially the skin, in SSc patients receiving ECP. ECP may be an effective and safe procedure for the treatment of SSc.

Review
Extracorporeal photopheresis is an immunomodulatory therapy indicated for patients with cutaneous T-cell lymphoma, graft-versus-host disease, and heart or lung allograft rejection. Whole blood from the patient is drawn into the photopheresis instrument where it is separated into its components. Plasma, red blood cells, and the treated buffy coat are subsequently returned to the patient. Consistent, adequate blood flow is necessary to successfully complete the procedure. Vascular access options for photopheresis include peripheral vein cannulation, tunneled central venous catheters, and subcutaneous ports. Photopheresis is a very safe procedure; however, the complications and impact on the patient's quality of life associated with vascular access devices can be significant.

Review
Graft versus host disease (GvHD) is one of the most feared adverse events of allogeneic hematopoietic stem cell transplantation. In severe grades of GvHD patients die from infections due to impairment of their immune defense or therapy-refractory involvement of intestines, liver and lung. Extracorporeal photopheresis is an effective treatment for acute and chronic graft versus host disease without severe impairment of the recipient's immune system. It is generally better known for its effect on skin GvHD but all other manifestations of GvHD can respond as well. Herein we report a brief review of its history and give an overview of the current knowledge of extracorporeal photopheresis in non-skin GvHD.

Review
BACKGROUND
Scleroderma is a heterogeneous group of diseases that can be localized or systemic. Localized scleroderma is a fibrosis of the skin characterized by inflammation and thickening due to excessive collagen deposition, and systemic sclerosis (SSc) is characterized by vasculopathy, immune dysregulation and skin fibrosis. In general, the prognosis of scleroderma highly depends on the degree of visceral involvement and relates to the degree of skin fibrosis. Despite the numerous therapies used for patients with scleroderma, the disease-related morbidity and mortality are high. Studies have explored the effects of extracorporeal photopheresis (ECP) in scleroderma treatment. Originally used in the treatment of cutaneous T-cell lymphoma, ECP is an immunomodulatory procedure in which a patient's white blood cells are treated with 8-methoxypsoralen and exposed to UVA radiation to inhibit cell proliferation and induce immunosuppression.
SUMMARY
Multiple lines of evidence suggest that ECP may be a safe and possibly effective therapy for patients with scleroderma, specifically demonstrating improvement in patients with cutaneous manifestations of the disease. However, future studies assessing its role in managing visceral involvement are needed. Our review aims to examine and consolidate the results of clinical studies and propose a possible role for ECP in the management of scleroderma.
KEY POINTS
ECP may be an effective and safe procedure for the treatment of SSc.
