Delayed-type hypersensitivity skin reaction estimated with Multitest CMI in human giardiasis.

Delayed-type hypersensitivity skin reaction performed with Multitest CMI as an indicator of cell-mediated immunity, has been evaluated among 20 adults with giardiasis. There were no correlation found between Multitest CMI score and clinical course of the disease, but significant correlation was observed in relation to CD4/CD8 ratio, an another indicator of cell-mediated immunity. Multitest CMI score revealed lower values in giardiasis patients than in controls, and it was associated with significantly higher frequency of hypoergic reactions among subjects.
