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.
