OBJECTIVE: To investigate the correlation between transformation growth factor (TGF- B) polymorphisms and IgA nephropathy and the therapeutic effect of dendrobium on IgA nephropathy.
METHODS: Polymerase chain reaction- restriction fragment length polymorphism (PCR- RFLP) and direct sequencing were used for analysis of 118 patients with IgA nephropathy from core families in Guangxi Zhuang Autonomous Region. The imbalanced transfer of TGF iso1-509 C/T in the affected offsprings was observed by transfer imbalance test and HRR analysis. The TGF-B genotype of the patients and the core family members were detected. The therapeutic effects of Dendrobium candidum combined with hormone and ACEI/ARB treatments were evaluated by observing the patient's urine protein (24 hUpr), serum albumin (ALB), creatinine (Scr) and urea nitrogen (BUN) levels.
RESULTS: In the 118 patients with IgA nephropathy, we identified TGF-B 1 promoter -509C/T genotype CC in 32 (27.1%) cases, CT in 58 (49.2%) cases, and TT in 28 (23.7%) cases. In the core family of the patients, CC genotype was found in 33 (28.0%) cases, CT in 55 (46.6%) cases, and TT in 30 (28.0%) cases. The treatments significantly lowered 24 hUpr, Scr, and BUN levels (P > 0.05) in patients with CC genotype, significantly lowered 24 hUpr and BUN levels in patients with CT genotype (P < 0.05), and significantly lowered 24 hUpr and BUN level and increased (P < 0.05) ALB level (P < 0.01) in patients with TT genotype.
CONCLUSIONS: There is no significant correlation between TGF-B promoter - 509C/T polymorphism and IgA nephropathy. The patients with CC genotype are sensitive to the treatments with hormone and ACEI/ ARB and show a stronger response to combined treatments with dendrobium.
