Estimation of major immunoglobulins in smokers and gutkha chewers

AIM: To estimate the level of IgG and IgA major immunoglobulins in patients having the habit of smoking, gutkha chewing and in patients without any tobacco habit as control. MATERIALS AND METHODS: Estimation of major immunoglobulins IgG and IgA was carried out by automated Nephelometry method in ten patients (control group), forty patients who had habit of smoking either bidi or cigarette and forty patients who had the habit of gutkha chewing. Among forty patients who smoked, twenty patients were without any lesion while twenty patients had homogenous leukoplakia. Among the forty patients who had habit of gutkha chewing, twenty patients were without any lesion while twenty patients had oral submucous fibrosis (OSMF). The obtained data were analyzed using independent sample t-test. RESULTS: IgG and IgA levels were higher in smokers and gutkha chewers as compared to control group and were higher in gutkha chewers as compared to smokers. IgG and IgA levels of non- lesional smokers and gutkha chewers showed no change as compared to the controls while it was increased in patients with homogenous leukoplakia and patients with OSMF as compared to control group. IgG and IgA levels were also significantly higher in patients with OSMF as compared to that of homogenous leukoplakia. IgG and IgA levels were higher in all the grades of OSMF as compared to the controls and both IgG and IgA levels were directly correlated with the grades of OSMF. CONCLUSION: Higher major immunoglobulins levels in present study among the study groups indicate the use of immunoprofile estimation in etiology and pathogenesis and would prove a great asset in the proper assessment of the lesions.
