Serum Gamma-Glutamyl Transferase and Ferritin Synergistically Associated with the Rate of Chronic Kidney Disease

الملخص EN

The present study investigated the effects of GGT and SF on the risk of CKD.

1024 participants (436 men and 588 women) were divided into three groups according to GGT and SF levels: group 1 (both GGT and SF not in the fourth quartile), group 2 (only GGT or SF in the fourth quartile), and group 3 (both GGT and SF in the fourth quartile).

The risks of CKD in different levels of GGT and SF and in groups 2-3 compared with group 1 were analyzed by multiple logistic regression.

GGT or SF in the highest quartile was associated with increased risk of CKD.

Such associations attenuated after adjustment for confounding factors.

The incidences of CKD, especially albuminuria, increased across the three groups.

Correspondingly, malondialdehyde (MDA) levels gradually increased from group 1 to group 3.

The risks of CKD were higher in groups 2 and 3 than that in group 1.

In group 3, the increased rate was independent of age, BMI, alcohol drinking, diabetes mellitus, hypertension, hypertriglyceridemia, and metabolic syndrome (odds ratios from 1.887 to 2.293, P<0.05).

In summary, this study suggested that GGT and SF synergistically influence the rate of CKD.
