ABSTRACT
Objective:To explore the correlation between the single nucleotide variation of profibrin-1 (PFN1) gene and secondary osteoporosis (OP) after stroke and its influence on bone metabolism indexes.Methods:120 patients with post-stroke hemiplegia who were treated in our hospital from Jan. 2019 to Jun. 2023 were selected as study objects and divided into OP group and non-OP group. Levels of vitamin D[25- (OH) D], tartrate-resistant acid phosphatase (TRAP) , osteocalcin (BGP) , serum type I procollagen amino terminal prolongation brain (P1NP) and type I collagen basal terminal β special sequence (β-CTX) were detected in all patients. Two SNPS (rs6559 and rs78224458) in PFN1 gene were genotyped.Results:There were significant differences in serum 25- (OH) D, TRAP, P1NP and β-CTX levels between OP group and non-OP group ( P<0.05) . The GG, GA and AA genotypes at rs6559 of PFN1 gene were significantly different between OP and non-OP patients ( P<0.05) . The combined model showed that compared with GG genotype carriers, the risk of secondary OP in GA and AA genotype carriers was 3.250 and 5.417 times higher, respectively. The results of the dominant model showed that the risk of secondary OP was 3.792 times higher in patients with mutant genes (GA or AA) than in patients with GG genotype. Recessive model results showed that patients with AA genotype had a 3.810-fold increased risk of secondary OP compared with GG and GA carriers. There was no significant difference in TT, TC, CC genotype distribution, genetic model and allele frequency at rs78224458 of PFN1 gene between OP patients and non-OP patients ( P>0.05) . There were no significant differences in 25- (OH) D, TRAP or BGP among the rs6559 GG, GA and AA genotypes of PFN1 gene ( P>0.05) , while there were significant differences in P1NP andβ-CTX levels among the three groups ( P<0.05) . Conclusion:The rs78224458 variation of PFN1 gene is associated with secondary OP in patients with hemiplegia after stroke, and may affect the bone metabolism indexes of patients.
