A SNP in the 5'UTR of GDF5 is associated with susceptibility to symptomatic lumbar disc herniation in the Chinese Han population.

ABSTRACT: PURPOSE: The aim of the present study is to assess whether the single nucleotide polymorphism in the GDF5 (+104T/C; rs143383) is associated with the symptomatic lumbar disc herniation in the Chinese Han population and the identification of the mechanisms of its action. METHODS: This study consisted of 231 patients with symptomatic lumbar disc herniation as the case group and 370 patients who had a lifetime lack of symptoms as the control group. PCR products were genotyped. Thirty-eight disc specimens derived from the cases were analyzed by immunohistochemical staining. The stain intensity of immunohistochemistry was quantified using a computerized image analysis system. RESULTS: Significant differences in genotypic and allelic frequencies were found between case group and control group (TT genotype P < 0.001; CC genotype P = 0.002; T allele P < 0.001). The T allele was more frequent in the case group regardless of gender (Female P = 0.018; Male P < 0.001). Significant differences were found in the genotype frequencies when stratified by gender except the comparison between the CC genotype and other genotypes combined among the female samples (P > 0.05). A semi-quantification of collagen protein in the nucleus pulposus showed that the average collagen protein content in TC group was higher than in TT group (P < 0.05). CONCLUSION: Our results suggested that the GDF5 polymorphism is associated with a susceptibility to symptomatic lumbar disc herniation in the Chinese Han population and type II collagen in the nucleus pulposus may be a key factor in susceptibility to symptomatic lumbar disc herniation.

Project description:Study designSecondary analysis of data from a concurrent randomized trial and cohort study.ObjectiveThe aim of this study was to determine risks and predictors of recurrent pain following standard open discectomy for subacute/chronic symptomatic lumbar disc herniation (SLDH).Summary of background dataMost previous studies of recurrence after discectomy do not explicitly define pain resolution and recurrence, and do not account for variable durations of time at risk for recurrence.MethodsWe used survival analysis methods to examine predictors of leg pain recurrence. For individuals with initial resolution of leg pain, we defined recurrent leg pain as having leg pain, receiving lumbar epidural steroid injections, or undergoing lumbar surgery subsequent to initial leg pain resolution. We calculated cumulative risks of leg pain recurrence using Kaplan-Meier survival curves, and examined predictors of recurrence using Cox proportional hazards models. We used similar methods to examine LBP recurrence.ResultsOne- and three-year cumulative risks of leg pain recurrence were 20% and 45%, respectively. One- and three- year leg pain recurrence risks were substantially lower in participants with complete initial resolution of leg pain (17% and 41%, respectively) than in those without (27% and 54%, respectively). In multivariate analyses, complete leg pain resolution (adjusted hazard ratio [aHR] 0.69; 95% confidence interval [CI] 0.52-0.90), smoking (aHR 1.68 [95% CI 1.22-2.33]), and depression (aHR 1.74 [95% CI 1.18-2.56]) predicted leg pain recurrence. The 1- and 3-year risk of LBP recurrence was 29% and 65%, respectively. LBP recurrence risk at 3 years was substantially lower in participants with complete initial resolution of LBP than in those without, but not at 1 year.ConclusionRecurrence of leg pain and LBP is common after discectomy for SLDH. Cumulative risks of both leg pain and LBP recurrence were generally lower in participants achieving complete initial resolution of pain post-discectomy.Level of evidence2.
