Purpose: Chronic Graft-Versus-Host Disease (cGVHD) is a significant cause of morbidity and mortality among post-allogeneic hematopoietic stem cell transplant (HCT) patients. Approximately 50% of patients that undergo HCT end up developing cGVHD. Few prognostic biomarkers exist to identify patients at risk for developing cGVHD. The purpose of our study was to determine if early assessment of Matrix Metalloproteinase-9 (MMP-9) and Dry Eye Questionnaire-5 (DEQ-5) had prognostic utility for the development of cGVHD and/or severe dry eye (DE) symptoms.

Methods: Participants underwent baseline InflammaDry and DEQ-5 screening on day 100 post-transplant (D+100). Patients were subsequently followed via DEQ-5 results at 6-, 9-, and 12-months post-transplant. The development of cGVHD was determined by chart review.

Results: The mean age of the study population was 54 years, 64% were female, 16% self-identified as white and 68% as Hispanic. Overall, 28% (n=7) of patients developed cGVHD over a mean follow up of 128 ± 63 days (range 45-216 days). At D+100, 32% (n=8) of patients had a positive MMP-9 in at least one eye and 20% (n=5) had a DEQ-5 ≥6. However, neither the presence of a positive MMP-9 nor a DEQ-5 score ≥6 at D+100 predicted the development of cGVHD (MMP-9: hazard ratio (HR) 1.53, p = 0.58, 95% confidence interval (CI): 0.34 – 6.85; DEQ-5 ≥6: HR 1.00, p = 1.00, 95% CI: 0.12 – 8.32). Additionally, neither of these measurements predicted the development of severe DE symptoms (DEQ-5 ≥12) over time (MMP-9: HR 1.77, p=0.58, 95% CI: 0.24-12.89; DEQ-5 >6: HR 0.03, p = 0.49, 95% CI: 0.00 – 889.93). Moreover, DEQ-5 scores tended to increase over time, irrespective of cGVHD development, but most patients (86%, n=6) who developed cGVHD did not show this pattern.

Conclusions: Within our small study population, DEQ-5 and MMP-9 assessment at D+100 did not predict the development of cGVHD or severe DE symptoms.
