To evaluate the role of lactate dehydrogenase as biomarker in the progression of potentially malignant disorders in smokers and gutkha chewers - Aim, Materials and Methods, Results, Conclusion

Q: How were participants grouped in the study?

Seventy individuals were divided into four groups: smokers only (20), gutkha chewers only (20), both smokers and gutkha chewers (20), and healthy controls (10).

Q: What key LDH findings were reported?

Significant decreases were reported in LDH-1 and LDH-2 in saliva, no effect on LDH-3, and a significant increase in salivary LDH-4, with significant correlations among groups.

Evaluate lactate dehydrogenase (LDH) as a salivary biomarker for progression of potentially malignant disorders among tobacco users, comparing smokers and gutkha chewers. A total of 70 participants were assigned to four groups: smoking only, gutkha chewing only, both habits, and healthy controls. Salivary LDH isoenzymes showed significant decreases in LDH-1 and LDH-2 with an increase in LDH-4, alongside significant correlation across groups and higher buccal micronuclei in oral exfoliated cells. Conclude a significant association between salivary LDH isoenzyme levels and cytomorphometric findings in oral epithelium.

Aim: To evaluate the role of lactate dehydrogenase (LDH) as a biomarker in the progression of potentially malignant disorders in smokers and gutkha chewers.
Material and Methods: The total of 70 individuals having the habit of chewing gutkha and smoking were selected for the study and divided into four groups. Group 1: 20 individuals having the habit of smoking, Group 2: 20 individuals having the habit of chewing gutkha, Group 3: 20 individuals having the habit of
smoking and gutkha chewing, and Group 4: 10 healthy individuals.
Results: In the present study showed that unstimulated whole saliva from group 1, group 2, and group 3 individuals, there was a significant decrease in isoenzymes LDH‑1 and LDH‑2 and there was no effect on LDH‑3 isoenzyme. In the present study, there is a significant increase in salivary isoenzyme LDH‑4 . The result indicated that there is an effect of carcinogen (tobacco)–enhanced activity on salivary LDH. The present study showed 70 volunteers reported a statistical significant correlation among the groups. The individuals with habit of smoking and gutkha chewing showed P value <.001 with a significant increase in the isoenzyme LDH‑4. A significant increase in the buccal micronuclei of exfoliated cells in the oral mucosal cells of smokers and gutkha chewers. This shows a positive relationship between LDH isoenzymes and the individuals with the smoking and chewing of tobacco.
Conclusion: There was a significant correlation between the levels of salivary LDH isoenzymes and cytomorphometric analysis of oral epithelium in smokers and gutkha chewers.
