Although there are many studies on the impact of Ramadan fasting on health in the medical literature, the effects have not been explored in Muslim patients undergoing extracorporeal photopheresis (ECP). This report aimed to describe the potential effects of Ramadan fasting on ECP treatment outcomes. Patients undergoing ECP were prospectively evaluated before and during the month of Ramadan 1443 AH (2022 AD) at the Abu Dhabi Stem Cells Center (ADSCC), United Arab Emirates. The following ECP outcomes were assessed: treatment completion, adverse events reported, body mass index (BMI), and laboratory test results, including complete blood count (CBC), C-reactive protein (CRP), and other systemic immune-inflammatory biomarkers (SIIBs). No statistically significant differences were found in most of the variables analyzed in the three patients who underwent ECP before and during the holy month. Two non-fasting patients were not able to complete the Ramadan ECP schedule, and one fasting patient experienced a vascular access event during his first procedure in Ramadan. These findings suggest that fasting during Ramadan could add further risk factors and develop serious complications related to the ECP treatment. Therefore, we suggest that fasting should be avoided during photopheresis treatment, and we provided recommendations to achieve the best possible clinical outcomes.

Extracorporeal photopheresis is an established procedure for refractory graft-versus-host disease, a major complication associated with notable morbidity and mortality in patients with allogeneic hematopoietic stem cell transplant. Despite being implemented over a decade ago, there is scant information about potential interactions or analytical interferences with concomitant drugs in this polymedicated population. Here we report the case of a pediatric patient diagnosed with cutaneous steroid-refractory acute graft-versus-host disease after unrelated allogeneic hematopoietic stem cell transplant that was treated with photopheresis. Analytical quantification of voriconazole by HPLC-PDA the day following photopheresis treatment did not permit therapeutic drug monitoring (TDM) due to the presence of interference at the voriconazole retention time. Following investigations, it was demonstrated that the interference is likely attributable to a psoralen-based compound. The interference was not present when samples were obtained prior to photopheresis, enabling TDM. This case underscores the relevance of communication among the members of the treating team to perform reliable TDM, especially in routine clinical practice of pediatric patients with complex diseases undergoing innovative treatments. This finding is relevant to voriconazole quantification by HPLC-PDA, frequently used in laboratories based in middle-income countries.

Propensity Score Matching Analysis Comparing the Efficacy and Steroid Tapering Benefit of Extracorporeal Photopheresis to Best Available Therapy in Third-Line or Beyond Treatment for Chronic GvHD.
Graft-versus host disease (GVHD) is one of the major limitations to allogeneic hematopoietic stem cell transplantation (HCT). Although corticosteroids with calcineurin inhibitors are established first line-therapy for chronic graft-versus-host disease (cGVHD), approximately one-half of cGVHD patients are refractory to corticosteroid therapy. The goal of the present study was to compare treatment outcomes of patients treated with extracorporeal photopheresis (ECP) and best available therapy (BAT) as third-line or beyond treatment for cGVHD. Using propensity score matching (PSM), treatment outcomes were compared between ECP-treated patients (n = 74) and a historical cohort of cGVHD patients treated with BAT (n = 132). By adjusting for unbalanced risk factors between the groups, including GVHD severity at the start of therapy, acute GVHD history, and baseline corticosteroid dose, 62 patients were balanced and selected for PSM. In the PSM cohort, the ECP group showed a 12-month failure-free survival (FFS) rate of 70.1% versus 32.5% in the BAT group (P < .0001; hazard rate [HR], .214), and 93.1% 12 months' overall survival (OS) rate of 93.1% versus 68.1% in the BAT group (P = .0249; HR, .3811); multivariate analysis confirmed ECP's superior FFS and OS compared with BAT. Generalized linear model analysis showed faster tapering of corticosteroids and higher rates of prednisone discontinuation in the ECP versus BAT PSM groups in the first 6 months. The ECP group also had a higher percentage of prednisone discontinuation, by 6% at month 0, by 14.9% at month 3, and by 22.5% at month 6. The current study demonstrates superior FFS, OS, and steroid tapering efficacy for ECP compared with BAT as third-line therapy or beyond in cGVHD patients.

Review
Extracorporeal photopheresis (ECP) is an FDA-approved immunotherapy for cutaneous T-cell lymphoma, which can provide a complete response in some patients. However, it is still being determined who will respond well, and predictive biomarkers are urgently needed to target patients for timely treatment and to monitor their response over time. The aim of this review is to analyze the current state of the diagnostic, prognostic, and disease state-monitoring biomarkers of ECP, and outline the future direction of the ECP biomarker discovery. Specifically, we focus on biomarkers of response to ECP in mycosis fungoides and Sézary syndrome. The review summarizes the current knowledge of ECP biomarkers, including their limitations and potential applications, and identifies key challenges in ECP biomarker discovery. In addition, we discuss emerging technologies that could revolutionize ECP biomarker discovery and accelerate the translation of biomarker research into clinical practice. This review will interest researchers and clinicians seeking to optimize ECP therapy for cutaneous T-cell lymphoma.

Single centre retrospective analysis of extracorporeal photopheresis (ECP) therapy in patients heavily pre-treated for chronic graft-versus-host disease (cGvHD) with steroid failure.
BACKGROUND
Extracorporeal photopheresis (ECP) is recommended as a second- or later-line therapy for chronic GvHD (cGvHD). Benefits include reasonable response with avoidance of intense systemic immunosuppression, which can translate into lowering the risk of systemic toxicity and opportunistic infection.
METHODS
We evaluated 75 patients treated with ECP for cGvHD from 2007 to 2021 at Princess Margaret Cancer Centre, and analyzed overall response rate (ORR) and clinical benefit (CB) at 3, 6 and 12 months plus other long-term treatment outcomes.
RESULTS
With a median follow-up of 72 months, a gradual increase in ORR was noted over time: 21% (16 out of 75 patients), 57% (36/63) and 70% (32/46) at month 3, 6 and 12, respectively. Gradual increase in CB was also observed over time with CB rate of 23% (17/75), 62% (39/63), and 76% (35/46) at months 3, 6 and 12, respectively. A total of 27 failures (36%) were noted, due to: 1) ECP resistance requiring switch to other therapy (n = 14, 19%), 2) non-relapse mortality (n = 10, 13%), 3) relapse of primary disease (n = 1, 1%) or 4) ECP procedure-related complication (n = 1, 1%, line infection), with 20 deaths (27%) observed. Failure-free survival (FFS) and overall survival (OS) rates were 68.3% and 85.9% at 12 months, respectively. After starting ECP, the proportions of patients who completely discontinued steroids were 17%, 32%, and 64% at months 3, 6 and 12, respectively.
CONCLUSION
ECP is an effective treatment option for heavily pre-treated cGvHD patients.

Extracorporeal photopheresis (ECP) has gained importance in the treatment of several diseases. Initially introduced as a new therapeutic modality for the treatment of patients with cutaneous T-cell lymphoma, the indications for the use of ECP have expanded to include hematology and transplantation immunology. Extracorporeal photopheresis has found its place in the treatment plan of cutaneous T-cell lymphoma, systemic sclerosis, graft-versus-host disease, organ transplantation such as heart and lung, sometimes as first-line therapy and very often in combination with various systemic immunosuppressive therapies. The procedure basically consists of three steps: leukapheresis, photoactivation and reinfusion. The following article presents possible theories about the mechanism of action, which is not yet fully understood, and discusses the five most common indications for ECP treatment with corresponding therapy recommendations.

Extracorporeal photopheresis (ECP) has shown efficacy in treating graft-versus-host disease (GVHD). We aim to summarize eight years of real-world experience with off-line ECP in our institution, in order to validate this treatment schedule and analyze predictive factors. All consecutive adult patients with steroid-dependent or steroid-refractory GVHD undergoing off-line ECP were included in this single-center retrospective study. ECP was performed with a Spectra Optia device, processing 1 total blood volume, at a twice-weekly frequency for acute GVHD (aGVHD) and once weekly for chronic GVHD (cGVHD), and tapered individually according to clinical response. The cumulative incidence of response, including complete response (CR) and partial response (PR), were compared among patients grouped by different baseline, apheresis, and disease characteristics. Between January 2015 and May 2022, a total of 1382 ECP procedures were proposed for 82 patients. No incidents were reported in 97% of the ECP sessions. GVHD responded in 78% of patients (aGVHD: 57% CR and 4% PR; cGVHD, 39% CR and 48% PR). Overall survival was statistically greater for aGVHD patients who responded to ECP compared to those who did not respond (67.5% versus 26% at 1 year; P = 0.037). Severity was an independent predictor of response in aGVHD, whereas the absence of mouth involvement and lower lymphocyte counts in the apheresis product correlated with a higher response in cGVHD. Our findings support the effectiveness of this treatment schedule for GVHD. Further investigation is required to identify ECP-specific predictive factors, given that findings are not homogeneous across studies.
