Lipid Profile Scores Predict Severity of Pemphigus: A Cross-Sectional Study

There is little evidence about the relationship between lipid indices and the severity of pemphigus vulgaris (PV) disease. In this cross-sectional study, we try to find out the exact relationship between three dietary lipid indices (PUFA/SFA ratio and ω-6/ω-3 index) and the severity of PV disease.

In this hospital-based cross-sectional study, a total of 138 pemphigus vulgaris cases were studied, of which 108 had PDAI ≤15, and 30 had PDAI>15. Dietary intakes were measured a valid 168-item FFQ. To calculate the lipid indices, the data received from diet were used.

After adjusting for potential confounders, people with the highest ω-6/ω-3 index had 32% lowest severity of PV disease compared to the people in the lowest category. However, this association was not significant in all models (OR: 0.68; 95% CI: 0.24-1.93, P _trend = 0.47). Moreover, people with the highest PUFA/SFA index had 9% highest severity of PV disease compared to the people in the lowest category. However, this association was not significant in all models (OR: 1.09; 95% CI: 0.34-3.51, P _trend = 0.88).

The evidence of our study shows that the relation between PUFA/SFA ratio and ω-6/ω-3 index is not significant. However, case-control studies are needed to confirm these findings.
