Tear Film Immunological Profile in Patients with Ocular Graft versus Host Disease.

PURPOSE: To analyze and compare the tear immunological profile in ocular GVHD (oGVHD) patients with that in non-oGVHD patients and to correlate them with ocular surface parameters based on the International Chronic Ocular GVHD Consensus Group (ICCGVHD) diagnostic criteria. METHODS: Tear samples from 20 individuals who underwent allo-hematopoietic stem cell transplantation and were grouped according the presence or absence of oGVHD were analyzed using Bio-Plex assay. RESULTS: IL-8 and MIP-1α levels were significantly higher in tears from oGVHD patients compared with those in tears from non-oGVHD patients (p<0.001 and p=0.001, respectively). Tear IL-8 levels correlated significantly with OSDI criteria (ρ=0.5159, p=0.001), ocular hyperemia (ρ=0.469, p=0.002), and corneal staining (ρ=0.339, p=0.032), whereas tear Mip-1α levels correlated with OSDI score (ρ=0.358, p=0.023). CONCLUSION: We demonstrated higher tear levels of IL-8 and MIP-1α in oGVHD patients and significant correlations between theses cytokines and ocular surface parameters based on the ICCGVHDCG criteria.

[Amniotic membrane transplantation for severe acute cases of chemical ocular burn and Stevens-Johnson syndrome]. / Transplante de membrana amniótica em casos agudos graves de queimadura ocular química e síndrome de Stevens-Johnson.

PURPOSE: To study the therapeutic potential of amniotic membrane transplantation in cases of severe acute chemical ocular burn and Stevens-Johnson syndrome. METHODS: We retrospectively reviewed the records of eight patients, with a total of ten eyes, submitted to amniotic membrane transplantation for treatment of ocular chemical burns and Stevens-Johnson syndrome in the acute phase between January 1999 and May 2008 in the Ophthalmology Department of UNIFESP. Data relating to sex, age, degree of chemical burns, etiology, affected eye, ophthalmological findings, extension of amniotic membrane, surgeries, additional time between the injury and surgery in days, visual acuity before and after surgery, epithelial defect healing (days), complications and time of follow-up in months were collected. RESULTS: The average age of patients was 35.7 +/- 23.04 years, with six men and two women. Three patients (four eyes) had Stevens-Johnson syndrome and five patients (six eyes) had chemical ocular burn. The epithelial defect was healed at an average of 27.8 +/- 4.7 days (ranging from 20 and 35 days). All patients presented limbal stem cell deficiency in a median follow-up of 7.8 +/- 2.8 months (ranging from six and twelve months) and four eyes developed symblepharon. CONCLUSIONS: The results suggest that the amniotic membrane transplantation represents an additive that can be carried out in the serious cases of ocular chemical burn and Stevens-Johnson syndrome with the finality of promoting the epithelialization and abolishing the inflammation and its consequences, if compared with other studies that treated similar cases with medical therapy only. On the other hand, it is not possible to avoid the limbic deficiency in these cases, which in the future will need limbal stem cell transplantation or other surgeries for correction of the ocular surface.

Transplante de membrana amniótica em casos agudos graves de queimadura ocular química e síndrome de Stevens-Johnson / Amniotic membrane transplantation for severe acute cases of chemical ocular burn and Stevens-Johnson syndrome

OBJETIVO: Investigar o potencial terapêutico do transplante de membrana amniótica nos casos agudos graves de queimadura ocular química e síndrome de Stevens-Johnson. MÉTODOS: Foram analisados retrospectivamente os prontuários de oito pacientes, com um total de dez olhos, submetidos a transplante de membrana amniótica para tratamento de queimadura ocular química e síndrome de Stevens-Johnson na fase aguda entre janeiro de 1999 e maio de 2008 no Departamento de Oftalmologia da UNIFESP. Dados referentes a sexo, idade, grau da queimadura, etiologia, olho acometido, achados oftalmológicos, extensão da membrana amniótica, operações adicionais, tempo em dias entre a lesão e a cirurgia, acuidade visual antes e depois da cirurgia, defeito epitelial em dias, complicações e tempo de seguimento em meses foram coletados. RESULTADOS: A idade média dos pacientes foi de 35,7 ± 23,04 anos, dos quais seis eram homens e dois eram mulheres. Três pacientes (quatro olhos) apresentaram síndrome de Stevens-Johnson e cinco pacientes (seis olhos) apresentaram queimadura ocular química. O defeito epitelial foi cicatrizado em média de 27,8 ± 4,7 dias (variando de 20 a 35 dias). Todos os pacientes evoluíram com deficiência límbica em seguimento médio de 7,8 ± 2,8 meses (variando entre cinco e doze meses) e quatro olhos desenvolveram simbléfaro. CONCLUSÕES: Os resultados sugerem que o transplante de membrana amniótica representa um aditivo que pode ser realizado nos casos agudos graves de queimadura ocular química e síndrome de Stevens-Johnson com a finalidade de promover a epitelização e suprimir a inflamação e suas consequências, se comparado a outros trabalhos que trataram casos semelhantes com terapia medicamentosa somente. Por outro lado, não é capaz de evitar a deficiência límbica nesses casos, que futuramente necessitarão de transplante de células-tronco do limbo ou outras cirurgias para correção da superfície ocular.
