RESUMO
Purpose: To understand the degree and explore the possible causes of ocular graft-versus-host disease (oGVHD) underdiagnosis in patients following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Patients and Methods: A 15-question survey was emailed to 6032 subscribers to the Blood and Marrow Transplant Information Network. A total of 371 respondents confirmed the history of allo-HSCT, of which 335 were symptomatic. Their self-reported symptoms, onset, treatments tried, degree of symptom control and established diagnoses of systemic chronic graft-versus-host disease (cGVHD) and oGVHD were analyzed. Results: Among the 335 symptomatic survey respondents, 306 reported their ocular symptom onset was after allo-HSCT, with only 170 [55.6% (170/306)] ever receiving a diagnosis of oGVHD; 23 reported worsening pre-existing ocular symptoms after allo-HSCT, with only 5 [21.7% (5/23)] ever receiving a diagnosis of oGVHD; 6 reported stable symptoms before and after allo-HSCT, with 1 ever receiving a diagnosis of oGVHD. Of the 176 respondents carrying the diagnosis of oGVHD, 167 [94.9% (167/176)] also had the diagnosis of cGVHD. Logistic regression analysis showed that the diagnosis of oGVHD was highly correlated with the number of symptoms and treatments one reported. Furthermore, 35% of the respondents with new onset ocular symptoms reported onset within the first 6 months after allo-HSCT (previously reported), as well as 39% of the respondents with worsened existing symptoms. Conclusion: oGVHD underdiagnosis is likely associated with the previous diagnostic criteria, in which cGVHD of another organ system was required. The correct notion that oGVHD commonly causes severe dry eye disease has likely led to its underdiagnosis in patients with fewer number of symptoms and/or who tried fewer treatments.
RESUMO
PURPOSE: To evaluate the utilization of scleral lenses and prosthetic replacement of the ocular surface ecosystem devices (SL/PDs) in the management of ocular graft-versus-host disease (oGVHD). PATIENTS AND METHODS: A survey of 15 questions was sent via email to 6032 subjects registered with the Blood and Marrow Transplant Information Network. The survey reviewed transplant history, graft-versus-host disease history, as well as oGVHD symptoms and onset. Additional questions surveyed treatments used for oGVHD, as well as the degree of ocular symptom control and experience with SL/PDs. A total of 306 respondents met the eligibility requirements to be part of the analyzed cohort. RESULTS: The mean number of symptoms reported from the analyzed cohort was 4.79 ± 2.44, median (IQR) of 5.0 (3.0 to 7.0), with the most common symptom being gritty, dry eyes (87%). The mean number of treatments utilized across the analyzed cohort was 3.21 ± 2.55, median (IQR) of 2.5 (1.0 to 5.0), with the most common treatment being artificial tears (86%). Wearing scleral lenses resulted in a mean of 5.42 ± 1.86, median (IQR) of 6.0 (4.0 to 7.0) symptoms improving, with improved dryness/grittiness of the eyes (94%), improved eye pain (92%) and improved quality of life (89%) being the most commonly improved symptoms. Fifty-six percent of those wearing scleral lenses wished the lenses had been recommended sooner. The most common reason patients cited for not wearing scleral lenses was that they had never heard of them (63%). CONCLUSION: SL/PDs help to control the symptoms of oGVHD. With their use, clinicians are able to improve the quality of life of this patient population. Despite the known benefits, SL/PDs still remain underutilized in oGVHD care. A majority of current SL/PD wearers wish that they had been recommended sooner as a treatment option. SL/PDs should be considered a component of comprehensive oGVHD management.
