Boost of innate immunity cytokines as biomarkers of response to extracorporeal photopheresis in patients with leukaemic cutaneous T-cell lymphoma. Br J Dermatol 2023; 189:603-611. [PMID: 37409661 DOI: 10.1093/bjd/ljad220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 06/28/2023] [Accepted: 06/30/2023] [Indexed: 07/07/2023]
Abstract
BACKGROUND Extracorporeal photopheresis (ECP) has emerged as a systemic first-line immunomodulatory therapy in leukaemic cutaneous T-cell lymphoma (L-CTCL) and is now beginning to be utilized in other T-cell-mediated diseases. Although ECP has been used for nearly 30 years, its mechanisms of action are not sufficiently understood, and biomarkers for response are scarce. OBJECTIVES We aimed to investigate the immunomodulatory effects of ECP on cytokine secretion patterns in patients with L-CTCL, to help elucidate its mechanism of action. METHODS A total of 25 patients with L-CTCL and 15 healthy donors (HDs) were enrolled in this retrospective cohort study. Concentrations of 22 cytokines were simultaneously quantified by using multiplex bead-based immunoassays. Neoplastic cells in patients' blood were evaluated by flow cytometry. RESULTS Firstly, we observed a distinct cytokine profile pattern difference between L-CTCLs and HDs. There was a significant loss of tumour necrosis factor (TNF)-α, and significant increase of interleukins (IL)-9, IL-12 and IL-13 in the sera of patients with L-CTCL compared with HDs. Secondly, patients with L-CTCL who received ECP were classified as treatment responders and nonresponders according to the quantitative reduction of malignant burden in their blood. We evaluated cytokine levels in culture supernatants from patients' peripheral blood mononuclear cells (PBMCs) at baseline and 27 weeks after ECP initiation. Strikingly, PBMCs purified from ECP responders released statistically higher concentrations of innate immune cytokines IL-1α, IL-1β, granulocyte-macrophage colony-stimulating factor (GM-CSF) and TNF-α in comparison with ECP nonresponders. In parallel, responders showed clearance of erythema, reduction of malignant clonal T cells in the blood, and a potent boost of relevant innate immune cytokines in individual patients with L-CTCL. CONCLUSIONS Taken together, our results demonstrate that ECP stimulates the innate immune network, and facilitates redirection of the tumour-biased immunosuppressive microenvironment towards proactive antitumour immune responses. The alterations of IL-1α, IL-1β, GM-CSF and TNF-α can be used as biomarkers of response to ECP in patients with L-CTCL.

Short treatment of peripheral blood cells product with Fas ligand using closed automated cell processing system significantly reduces immune cell reactivity of the graft in vitro and in vivo. Bone Marrow Transplant 2022; 57:1250-1259. [PMID: 35538142 PMCID: PMC9088133 DOI: 10.1038/s41409-022-01698-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 04/14/2022] [Accepted: 04/26/2022] [Indexed: 11/08/2022]
Abstract
Mobilized peripheral blood cells (MPBCs) graft and peripheral blood cells apheresis are used for bone marrow transplantation and for treatment of graft versus host disease (GvHD). We demonstrate that a short treatment of MPBCs with Fas ligand (FasL, CD95L) for 2 h using a closed automated cell processing system selectively induces apoptosis of specific donor T cells, B cells and antigen presenting cells, but, critically, not CD34+ hematopoietic stem cells and progenitors, all of which may contribute to an increased likelihood of graft survival and functionality and reduced GvHD. Treated cells secreted lower levels of interferon-gamma as compared with control, untreated, cells. Moreover, FasL treatment of immune cells increased signals, which led to their phagocytosis by activated macrophages. FasL treated immune cells also reduced the ability of activated macrophages to secrete pro-inflammatory cytokines. Most importantly, FasL ex vivo treated MPBCs prior to transplantation in NOD-SCID NSG mice prevented GvHD and improved stem cell transplantation in vivo. In conclusion, MPBCs, as well as other blood cell products, treated with FasL by automated manufacturing (AM), may be used as potential treatments for conditions where the immune system is over-responding to both self and non-self-antigens.

Abstract
BACKGROUND Systemic sclerosis (scleroderma) (SSc) is a rare autoimmune disorder characterized by excessive production of collagen. Extracorporeal photopheresis (photochemotherapy, phototherapy) (ECP) involves repeated exposure of peripheral blood lymphocytes to ultraviolet A (UVA) radiation. The rationale for treating patients with SSc by ECP lies in its presumed immunomodulatory effects, though, rigorous data on the specific effects of ECP are limited, particularly in patients with SSc. The objective was to evaluate the effects of extracorporeal photopheresis as a treatment modality for patients with SSc. METHODS We searched the databases CENTRAL and MEDLINE on 13 March 2022 and included randomized clinical trials (RCTs) on patients diagnosed with SSc and treated with ECP. Primary outcome was the change of skin scores. We applied independent extraction and judgment by multiple observers. We conducted a meta-analysis applying the inverse variance method and the random effects model; the main outcome measure was standard mean difference of skin scores. RESULTS We identified three relevant randomized clinical trials including 162 randomized (132 analyzed) people who received ECP in a simple parallel design. Pooled data of the three studies were indifferent. We estimated a standard mean difference from baseline of -0.11 (95% confidence interval -0.45 to 0.23), p = 0.54, I2 = 0%. We did not identify serious treatment-related adverse events. CONCLUSIONS The evidence base for extracorporeal photopheresis on skin scores in patients with systemic sclerosis was not high enough to support a superior effect when compared to no treatment, sham photopheresis, or D-penicillamine.

Abstract
Phototherapy is a recommended treatment regimen for different scleroderma spectrum disorders, but so far it has been included neither by European nor by worldwide experts committee in recommendations for the treatment of systemic sclerosis (SSc). The aim of the study was to revisit the utility of dermatological phototherapy in patients with SSc. PubMed using medical subject headings was searched to identify studies evaluating response to dermatological phototherapy in SSc patients. Both UVA1 (340-400 nm) and PUVA (psoralen plus UVA) treatments were found to reduce skin thickening and increase skin elasticity, therefore allowing for the improvement of joint tension mobility, especially in hands. At least several papers showed efficacy of phototherapy in patients who remained non-responsive to previous immunosuppressive therapies. The most probable mechanisms of action of phototherapy in SSc include inhibition of T-cells and prevention from dermal fibrosis. Although most data on the efficacy of phototherapy come from small experimental studies and case reports, phototherapy based on UVA of wavelength manifests relatively mild spectrum of side effects and this should be considered as a treatment option for SSc with dominant cutaneous involvement.

Abstract
B cells play a central role in the pathogenesis of many autoimmune diseases, acting as antigen-presenting cells, producing inflammatory cytokines, and acting as a source of autoantibodies after differentiating into plasma cells. In this review, we aim to summarize and synthesize the literature for the utility of biomarkers of B cell activation (plasma immunoglobulins (Ig), free light chains (FLCs), and beta-2 microglobulin (β2M)) in monitoring inflammatory rheumatic connective tissue diseases, such as Sjogren's syndrome (SS), systemic lupus erythematosus (SLE), dermatomyositis (DM), and systemic sclerosis (SSc). Clinically, it is quite difficult to gauge prognosis in these conditions as there, historically, have not been many quantitative markers of disease activity available. From our extensive literature review, Ig, FLC, and β2M may function as invaluable prognostic markers of ongoing disease activity, and potentially as biomarkers for response to therapy or disease relapse. They are inexpensive and unsophisticated tests that are vastly underused in the setting of autoimmune disease. However, clinicians still need to be aware of the potential of false positives in times of infection or plasma cell dyscrasia, as these disease states can artificially increase these biomarkers. Ultimately, the utility of serum Ig, FLCs, and β2M is clearly delineated in SS and SLE, and least investigated in DM, and additional prospective studies utilizing these biomarkers, and specific B cell targeted therapies are still needed.

Abstract
BACKGROUND Extracorporeal photopheresis (ECP) has been considered for treatment of patients with systemic sclerosis (SSc). OBJECTIVES To study the 12-month effects of ECP on laboratory parameters and evaluate the SSc-related long-term survival. METHODS 59 SSc patients who had received at least 6 ECP cycles were included. Lab parameters were assessed at baseline (ECP naïve), after 6 months, and after 12 months. 20-year follow-up data were collected for all patients. RESULTS 31 (59/52.5%) patients presented with elevated serum III procollagen (sPIIINP) levels at baseline which significantly declined after 6- and 12-month ECP. Total lymphocyte counts as well as circulating immune complexes (CICs) significantly decreased after 12-months ECP. On long-term follow-up, patients had received a median of 37.5 (6-167) ECP cycles over a median period of 64 (6-281) months. 20-year follow-up revealed only 8 (59/13.6%) SSc-related deaths and 51 (59/86.4%) survivors. CONCLUSIONS One-year ECP induces changes in lab parameters, such as sPIIINP, CICs, and lymphocyte counts, which have previously been implicated in the pathogenesis of SSc. More importantly, our data reveal, for the first time, that ECP-treated SSc patients appear to have extremely favorable 20-year survival rates compared to other SSc cohorts reported in the literature.

Abstract
The discovery of endogenous cannabinoid receptors CB1 and CB2 and their endogenous ligands has generated interest in the endocannabinoid system and has contributed to the understanding of the role of the endocannabinoid system. Its role in the normal physiology of the body and its implication in pathological states such as cardiovascular diseases, neoplasm, depression and pain have been subjects of scientific interest. In this review the authors focus on the endogenous cannabinoids, and the critical role of cannabinoid receptor signaling in neurodegeneration and other inflammatory responses such as gut, joint and skin inflammation. This review also discusses the potential of endocannabinoid pathways as drug targets in the amelioration of some inflammatory conditions. Though the exact role of the endocannabinoid system is not fully understood, the evidence found much clearly points to a great potential in exploiting both its central and peripheral pathways in disease management. Cannabinoid therapy has proven promising in several preclinical and clinical trials.

Abstract
Cannabinoids are increasingly-used substances in the treatment of chronic pain, some neuropsychiatric disorders and more recently, skin disorders with an inflammatory component. However, various studies cite conflicting results concerning the cellular mechanisms involved, while others suggest that cannabinoids may even exert pro-inflammatory behaviors. This paper aims to detail and clarify the complex workings of cannabinoids in the molecular setting of the main dermatological inflammatory diseases, and their interactions with other substances with emerging applications in the treatment of these conditions. Also, the potential role of cannabinoids as antitumoral drugs is explored in relation to the inflammatory component of skin cancer. In vivo and in vitro studies that employed either phyto-, endo-, or synthetic cannabinoids were considered in this paper. Cannabinoids are regarded with growing interest as eligible drugs in the treatment of skin inflammatory conditions, with potential anticancer effects, and the readiness in monitoring of effects and the facility of topical application may contribute to the growing support of the use of these substances. Despite the promising early results, further controlled human studies are required to establish the definitive role of these products in the pathophysiology of skin inflammation and their usefulness in the clinical setting.
