Detection of salivary interleukin-2 in recurrent aphthous stomatitis

The present study was undertaken to estimate and compare salivary interleukin-2 (IL-2) levels in patients with recurrent aphthous stomatitis, among healthy controls and their variation with age and sex. Saliva was collected from 60 patients within the age range of 16-60 years which included 30 patients (17 Females and 13 Males) with recurrent aphthous stomatitis and healthy control group consisted of 30 participants (18 Females and 12 Males). IL-2 estimation was done in both the groups using enzyme linked immunosorbent assay (ELISA). Statistical analysis of the data was done using Independent 't' test. The results showed increased salivary IL-2 levels in patients with recurrent aphthous stomatitis compared to the healthy controls. The IL-2 levels were also increased in patients with the age group of 16-30 years compared to other age groups. Similar increase of IL-2 was also seen in female patients. Age related and sex related alterations of IL-2 in recurrent aphthous stomatitis patients were observed.
