Comparison among different diagnostic criteria for chronic ocular graft-versus-host disease applied with and without pre-transplant ophthalmological examination.

purposeTo compare the proportion and the agreement rate in the diagnosis of chronic ocular graft-versus-host disease (GVHD) among three criteria applied with and without ophthalmological examination before hematopoietic stem cell transplantation (HSCT).

methodsNational Institutes of Health (NIH), International Consensus Criteria on ocular GVHD (ICCGVHD) and TFOS Dry Eye Workshop (DEWS) II criteria were used for the diagnosis of ocular GVHD according to two protocols: ophthalmological examination after HSCT (Protocol A), or before and after HSCT (Protocol B). Proportion of GVHD diagnosis and inter-rate agreement coefficient Kappa (K) among the criteria were calculated.

resultsOne hundred nine patients undergone HSCT were included. NIH, ICCGVHD and DEWS II criteria diagnosed ocular GVHD in 14.7%, 17.4% and 59.6% of the patients (Protocol A), whereas in 11.9%, 15.6% and 33.0% of the HSCT patients (Protocol B). The coefficient K for the proportion of patients diagnosed with ocular GVHD by NIH and ICCGVHD criteria was K = 0.626 (Protocol A) and K = 0.615 (Protocol B). The K coefficient by NIH and DEWS II criteria was K = 0.144 (Protocol A), and K = 0.233 (Protocol B). The K coefficient by ICCGVHD and DEWS II criteria was K = 0.250 (Protocol A) and K = 0.499 (Protocol B). The K coefficient for ocular GVHD diagnosis applying Protocol A and B was K = 0.881 if NIH criteria were used, K = 0.933 if ICCGVHD criteria were used and K = 0.501 if DEWS II criteria were used.

conclusionsThe diagnosis of ocular GVHD varied significantly in our cohort of hematological patients according to both the diagnostic criteria used and the visit protocols applied.
