ABSTRACT
INTRODUCTION:
The Institute of Hematology and Transfusion Medicine (IHTM) in Warsaw has produced autologous serum eye drops (ASEDs) for the treatment of Dry Eye Syndrome (DES) since 1991. In 2019, IHTM introduced allogeneic tears (alloSEDs) for patients on long-term treatment. MATERIALS ANDMETHODS:
114 patients who applied alloSEDs were included in the study.They were asked to complete the OSDI questionnaire before and after using ASEDs and 100 units of alloSEDs drops from each donation. The OSDI index rates DES severity (0 no symptoms; 100 severe). We also compared the content of IL-1ß, IL-2, IL- 6, IL-10 and VEGF in ASEDs (38 samples) and alloSEDs (15 serum samples). The study data covered the 2019-2022 period.RESULTS:
114 patients participated in the study. We compared the the effectiveness of ASEDs and alloSEDs. The average, OSDI dropped from 68.42 ± 5,86 (before application) to 51.05 ± 19,06 (after application). Data from the questionnaires (prepared at IHTM) completed and returned (41/114) present the most common indications for the use of serum drops, including DES with no underlying disease, DES secondary to GvHD (Graft versus Host Disease), Sjögren's Syndrome (SS). The study reported higher cytokine levels associated with disease entities such as SS. After application of drops with high cytokine levels, patients reported adverse reactions such as sand under the eyelids, impaired visual acuity, and worse eye lubrication.CONCLUSIONS:
AlloSEDs with acceptably low values of pro-inflammatory cytokines and sufficiently high levels of VEGF growth factor may contribute to alleviation of inflammatory eye symptoms.Palavras-chave
