- Cell products are live cells that are given to patients in order to replace or modify the function of missing or dysfunctional cells. Progress in technology and in the understanding of pathobiology may lead to the use of cell products in many areas. This review outlines the use of cell products in the treatment of autoimmune diseases, with focus on neuroinflammatory diseases like multiple sclerosis. Treatment of autoimmune diseases should be selective and specific in order to avoid serious side effects. To achieve this, T lymphocyte regulation has been in focus for several immunomodulatory regimens. One area of great interest is the use of T cell vaccination, when autologous attenuated auto-reactive T cells are given to patients in order to initiate a specific immune response to the pathogenic T cell populations. Phopheresis may be an immunomudulatory treatment related to T cell vaccination. Another promising area involves ex-vivo alteration of the cytokine profile of harmful auto-reactive T cells. This can be achieved by genetic manipulation or by certain cytokine stimulations. A subsequent adoptive cell transfer will, by homing mechanisms, lead to at site specific delivery of the cells, which will have a local down-regulatory effect on the inflammatory process. Although unsolved questions regarding doses, timing, optimal preparing conditions and mechanisms still remain, both T cell vaccination and adoptive transfer of ex-vivo manipulated cytokine secreting cells have proven successful for treatment of neuroinflammation in experimental models. T cell vaccination was shown to be feasible in patients with multiple sclerosis, however, otherwise the experience in humans so far is limited.

- Photopheresis has been claimed to have immune-modulating effects, but the mechanisms of action are unknown. This study investigated the immune effect of photopheresis in children with type 1 diabetes, with a focus on the balance of Th1- and Th2-like cytokines. Ten children with newly diagnosed type 1 diabetes (10-17 y) were treated with five double treatments of photopheresis and 10 children matched for disease, age, and gender were given placebo tablets and sham pheresis. Expression of IFN-γ and IL-4 mRNA was determined by real-time reverse-transcriptase polymerase chain reaction (RT-PCR) and secretion of IFN-γ, IL-10, and IL-13 in cell-culture supernatants by ELISA after stimulation with glutamic acid decarboxylase (GAD65) (a.a. 247-279), the ABBOS peptide (a.a. 152-169), insulin, phytohemagglutinin (PHA), and keyhole limpet hemocyanin (KLH). Photopheresis changed antigen-stimulated immune balance in line with a Th2-like shift. Thus, the ratio of IFN-γ/IL-4 mRNA expression after in vitro stimulation with a peptide of the autoantigen GAD 65 was reduced after treatment in the photopheresis group. The IFN-γ/IL-4 mRNA expression ratio after in vitro stimulation with insulin was also lower in children treated with photopheresis compared with the placebo group. Photopheresis has an immune-modulating effect in children with type 1 diabetes, causing a Th2-like deviation. Copyright © 2005 International Pediatric Research Foundation, Inc.

European dermatology forum : Updated guidelines on the use of extracorporeal photopheresis 2020 - Part 2

- BackgroundFollowing the first investigational study on the use of extracorporeal photopheresis for the treatment of cutaneous T‐cell lymphoma published in 1983, this technology has received continued use and further recognition for additional earlier as well as refractory forms. After the publication of the first guidelines for this technology in the JEADV in 2014, this technology has maintained additional promise in the treatment of other severe and refractory conditions in a multidisciplinary setting. It has confirmed recognition in well‐known documented conditions such as graft‐vs.‐host disease after allogeneic bone marrow transplantation, systemic sclerosis, solid organ transplant rejection including lung, heart and liver and to a lesser extent inflammatory bowel disease.Materials and methodsIn order to further provide recognized expert practical guidelines for the use of this technology for all indications, the European Dermatology Forum (EDF) again proceeded to address these questions in the hands of the recognized experts within and outside the field of dermatology. This was done using the recognized and approved guidelines of EDF for this task. All authors had the opportunity to review each contribution as it was added.Results and conclusionThese updated 2020 guidelines provide at present the most comprehensive available expert recommendations for the use of extracorporeal photopheresis based on the available published literature and expert consensus opinion. The guidelines were divided into two parts: PART I covers Cutaneous T‐cell lymphoma, chronic graft‐vs.‐host disease and acute graft‐vs.‐host disease, while PART II will cover scleroderma, solid organ transplantation, Crohn’s disease, use of ECP in paediatric patients, atopic dermatitis, type 1 diabetes, pemphigus, epidermolysis bullosa acquisita and erosive oral lichen planus.

- A patient with paraneoplastic cerebellar degeneration due to anti-Purkinje cell antibodies (anti-Yo) arising from ovarian carcinoma with metastases was treated with three plasmapheresis (PP) series (a total of 22 PP treatments) over one year and was monitored by repeated otoneurological testing, balance tests and clinical investigations. Blood samples for antibody titers were checked on several occasions. Initially there was a weak clinical response and significantly improved test results regarding the caloric response, as well as a possible effect on visual suppression of the vestibulo-ocular reflex after caloric ear irrigation. After the first series of PP treatment, new metastases were found. A half year later there was a progressive course with increasing general symptoms. Serology tests showed continuously high titers of anti-Yo antibody, although somewhat lower after PP. We thus report a minor and short-lived effect of PP, possibly inhibited by the natural course of metastatic disease. © 2008 International Society for Apheresis.
