Objective: A prospective clinical study to assess the utility of CD4 + T cell lymphocyte profiling from peripheral blood in patients with ocular tuberculosis (TB). Methods: Thirty-six Asian patients with presumed diagnosis of ocular TB were recruited for T-lymphocyte profiling. MTB antigen specific CD4 assay was set up, and flow cytometric data were analyzed using FlowJo software. Results: There was no significant difference between treatment responders and non-responders for the proportion of CD4 + T cells specific for PPD or ESAT-6+ CFP-10, but treatment responders did have significantly higher frequency of CD38+ (p = .0357) and CD38+ HLA-DR+ (p = .0357) on the PPD-specific CD4 + T cells. Conclusion: This study is one of the first of its kind to look into MTB specific T cell activation marker profiling of peripheral blood in patients with ocular TB. Further studies need to be undertaken to assess the utility of CD4 + T cell phenotypes as a biomarker for ocular TB.
