Comparative role of 20% cord blood serum and 20% autologous serum in dry eye associated with Hansen's disease: a tear proteomic study.

BACKGROUND: To compare the role of topically applied serum therapy with preservative-free artificial tear (AT) drops in patients with moderate to severe dry eye in Hansen's disease along with change in tear protein profile. METHODS: 144 consecutive patients were randomly divided into three groups. After a baseline examination of clinical parameters, each of the patients received designated modality of topical therapy six times a day for 6 weeks. Post-treatment documentation of clinical parameters was done at 6 weeks, and then at 12 weeks after discontinuation of topical therapy. Analysis of three tear proteins using gel electrophoresis (sodium dodecyl sulfate polyacrylamide gel electrophoresis) was done at baseline, at the first and second post-treatment visits. RESULTS: In the cord blood serum (CBS) group, except for McMonnies score and staining score, all other clinical parameters showed continued improvement in the first and second post-treatment analyses. In the autologous serum (ALS) group, all the clinical parameters except Schirmer's I showed significant improvement in the first post-treatment analysis .This was sustained at a significant level in the second analysis except for tear film break-up time (TBUT) and conjunctival impression cytology grading. In the AT group, all the parameters improved at a non-significant level except for TBUT in the first analysis. In the next analysis, apart from McMonnies score and TBUT, other clinical parameters did not improve. In the ALS and CBS groups, tear lysozyme, lactoferrin levels improved in both post-treatment measurements (statistically insignificant).Total tear protein continued to increase at statistically significant levels in the first and second post-treatment analyses in the CBS group and at a statistically insignificant level in the ALS group. In the AT group, the three tear proteins continued to decrease in both the analyses. CONCLUSIONS: In moderate to severe dry eye in Hansen's disease, serum therapy in comparison with AT drops, improves clinical parameters and causes betterment in tear protein profile.

Avaliação e tratamento do olho seco na hanseníase / Assessment and treatment of the dry eye in Hansen's disease

O Reconhecimento do grande número de pacientes com ressecamento de córnea e a inexistência de publicações neste ramo, motivou os autores a elaborar o presente trabalho. Forma examinados um total de 150 pacientes de Fevereiro a Maio/86, sendo 66% da forma Virchoviana, 16,6% forma Borderline, 16,6% foram Tuberculóide. Em 62% dos pacientes examinados apresentam ressecamento de córnea, tendo como principais causas baixa produção da lágrima, triquíase, lagoftalmo I (inicial) e avançado ectrópio. O tratamento dos pacientes durante o período foi dividido conforme a gravidade do problema em duas categorias: lubrificação da córnea com lubrificante artificial simples e lubrificação completa e em casos de triquíase usou-se no tratamento a retirada dos cílios. Pelos resultados obtidos (100% de melhora do ressecamento de córnea) observou-se o êxito do trabalho.
