Ethnopharmacological relevance: Tongue coating diagnosis is a useful tool to examine the changes of a human body in Chinese Medicine. Tongue coating varies in thickness in kidney disease. However, little information exists regarding the association between clinical characters and tongue coating thickness in CKD patients.
Aim of the study: This study was carried out to determine whether there is an association between tongue coating thickness and laboratory, histological variables in idiopathic membranous nephropathy patients: one group with thin tongue coating, the other with thick tongue coating.
Materials and methods: During July 2012-March 2014, idiopathic membranous nephropathy patients (CKD 1-2 stage) with tongue coating thickness Score <= 7, or >= 11, were enrolled as thin tongue coating group or thick tongue coating group, from Hangzhou Hospital of TCM. Laboratory variables (Hemoglobin (Hb), albumin (Alb); eGFR; alanine transferase (ALT); aspartate aminotransferase (AST); triglyceride (TG); total cholesterone (TC); high density lipoprotein (HDL); low density lipoprotein (LDL); immunoglobin A, G, M; Complement 3, 4) and renal histological data (glomerular lesions; tubular-interstitial damage) were compared, between these two groups.
Results: 12 idiopathic MN patients (CKD 1-2 stage) with thin tongue coating (tongue coating thickness score 7) and 11 with thick tongue coating (tongue coating thickness score > 11) were enrolled in our study. We found a significant lower level of TC and LDL, a significant lower level of AST, ALT in those thick tongue coating patients, compared with thin. No significant difference was observed in pathological lesion between thick and thin tongue coating patients.
Conclusion: Tongue coating thickness is associated with lipid metabolism in idiopathic MN patients (CKD 1-2 stages). o 2015 Elsevier Ireland Ltd.
