Lee YH, Song GG. Circulating leptin level in osteoarthritis and associations between leptin receptor polymorphisms and disease susceptibility: A meta-analysis. Int J Rheum Dis 2023. [PMID: 37183731 DOI: 10.1111/1756-185x.14730] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 04/27/2023] [Accepted: 04/29/2023] [Indexed: 05/16/2023]
Abstract
OBJECTIVE This study aimed to systemically review the evidence on the relationship between the circulating leptin levels and osteoarthritis (OA), and the association between leptin and leptin receptor (LEPR) polymorphisms and OA susceptibility. METHODS To find relevant papers (up to February 2023) examining the association between circulating leptin levels, LEPR polymorphisms, and OA, the PUBMED, EMBASE, and Cochrane databases were searched. We performed a meta-analysis to examine the levels of synovial and serum/plasma leptin in OA patients compared with healthy controls, as well as the relationship between OA and LEPR polymorphisms. RESULTS Data from 15 investigations, totaling 2197 patients with OA and 2546 controls, were included in the meta-analysis. There were statistically significant differences in the levels of circulating leptin between the OA and control groups (standardized mean difference [SMD] 2.178, 95% confidence interval [CI] 1.208-3.139, P = 0.001). Leptin levels were also substantially greater in European, Asian, and Arab groups among OA patients. After adjusting for age, sex, and/or body mass index, the leptin levels of patients with OA were significantly higher. Similarly, regardless of sample size (n < 100 and n ≥ 100) or year of publication, leptin levels were considerably higher in the OA group. In addition, the synovial leptin level was greater in the OA group than in the control group (SMD 0.783; 95% CI 0.247-1.319, P = 0.004). In the LEPR rs1137101 polymorphism, the OA and AA genotypes were significantly associated (odds ratio 0.282, 95% CI 0.126-0.629, P = 0.002), according to the meta-analysis. Ethnic stratification revealed an association between OA and the LEPR rs1137101 AA genotype in Asian and Arab populations. CONCLUSION The results of this meta-analysis indicate that patients with OA had considerably greater levels of circulating leptin than did control individuals. In addition, synovial leptin levels were greater in OA patients than in healthy individuals, and the LEPR rs1137101 polymorphism was linked to an increased risk of developing OA. These results imply that leptin participates in the onset and progression of OA.

Abstract
Abstract
Background
Osteoarthritis (OA) is a highly prevalent medical condition which represents a high impact on public health. In addition, the underlying etiology still has been unelucidated. Osteoarthritis is a multifactorial disease with a high genetic predisposition. Identification of genes associated with higher OA predisposition can assist in elucidating the underlying molecular mechanisms as well as detecting possible areas for gene-targeted OA therapies. Among these genetic targets, double Von Willebrand factor domain A (DVWA) has been shown to be related to β-tubulin protein interaction which is considered a protecting factor from OA development. Studies have shown a reduction in protein binding strength with single-nucleotide polymorphism (SNP) rs11718863 in the Von Willebrand factor domain A (VWA domain). Development of weakness between β-tubulin and the wild protein has been linked with increased risk of OA development. We aimed to investigate the association between primary knee OA susceptibility and severity with DVWA rs11718863 SNP among a subset of Egyptian population.
Results
There was no statistically significant difference in the incidence of AA, AT and TT genotypes frequencies between patient group and control group (P = 0.502). There was no statistically significant difference between different genotypes of DVWA rs11718863 SNP as regards the radiological assessment of different knee joint compartments using Kellgren Lawrence scale (P = 0.960 for medial tibiofemoral compartment), (P = 0.260 for lateral tibiofemoral compartment) and (P = 0.597 for patellofemoral compartment).
Conclusions
DVWA rs11718863 SNP was not demonstrated to influence OA susceptibility and severity among the studied Egyptian population subset. Larger sample size with inclusion of more genetic variants of DVWA SNP would be necessary to support the presence or absence of any relationship between DVWA SNP and OA.

Abstract
Abstract
Background
Primary osteoarthritis is considered one of the most common and the most studied musculoskeletal disorder. Nevertheless, the risk factors remain unclear. A disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) 14 (ADAMTS14) gene is involved in the cleavage of amino-terminal propeptides from type II procollagen, a necessary step in the formation of collagen fibers. The abnormal metabolism of collagen fibers type II leads to a decreased mechanical strength of joint cartilage which is one of the most important contributing factors to joint osteoarthritis. We aimed at investigating the association between primary osteoarthritis and ADAMTS14 gene rs4747096 single nucleotide polymorphism in a sample of Egyptian patients and analyzing the relationship between this genetic polymorphism with the severity of osteoarthritis. Sixty-five Egyptian patients who fulfilled the American College of Rheumatology criteria for primary knee osteoarthritis were compared with thirty-one apparently healthy subjects. Genotyping was performed by TaqMan single nucleotide polymorphism genotyping assay.
Results
There was a statistically significantly higher frequency of AA genotype among osteoarthritis patients compared to the control group (P = 0.004). The number of affected hand joints was significantly higher among patients with ADAMTS14 AA genotype in comparison to patients with ADAMTS14 AG genotype (P = 0.002). In addition, AA genotype was associated with statistically significantly higher Kellgren-Lawrence radiological grades in the knee and hand joints (proximal interphalangeal and thumb interphalangeal joints) (P = 0.037, 0.003, and 0.030 respectively).
Conclusion
The study showed an association between the AA genotype of ADAMTS14 gene rs4747096 single nucleotide polymorphism with knee and hand osteoarthritis and osteoarthritis severity in these joints. The AA genotype of ADAMTS14 gene rs4747096 single nucleotide polymorphism could be implicated in the increased incidence of primary osteoarthritis development and elevated disease severity among the Egyptian population.

Abstract
Background Adipokines gene polymorphisms are speculated to be associated with the risk of knee osteoarthritis (OA), but evidence remains conflicting. This study therefore aimed to examine whether associations exist between adipokines gene polymorphisms and knee OA by considering the evidence collected from eligible studies through a meta-analysis. Methods A systematic search was performed on PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang up to March 31, 2020. Meta-analysis was carried out by focusing on the associations between adipokines gene polymorphisms and knee OA with the allele model, dominant model, and recessive model. Results The present meta-analysis included 5 eligible studies for ADIPOQ rs1501299 with 1,021 cases and 1,097 controls, 3 eligible studies for ADIPOQ rs2241766 with 549 cases and 544 controls, 3 eligible studies for LEPR rs1137101 with 808 cases and 856 controls, 2 eligible studies for VISFATIN rs4730153 with 339 cases and 680 controls and 2 eligible studies for VISFATIN rs16872158 with 339 cases and 680 controls. Significant association was observed between LEPR rs1137101 and knee OA in the overall population (recessive: OR = 0.40, 95% CI 0.21–0.79). Limited data revealed that associations may exist between ADIPOQ rs2241766 and knee OA in Asians (dominant: OR = 1.35, 95% CI 1.03–1.78), between VISFATIN rs4730153 and knee OA in Asians (allele: OR = 0.58, 95% CI 0.41–0.83; dominant: OR = 0.57, 95% CI 0.39–0.83), and between VISFATIN rs16872158 and knee OA in Asians (allele: OR = 1.84, 95% CI 1.26–2.68; dominant: OR = 1.94, 95% CI 1.31–2.89). Conclusions Adipokines gene polymorphisms may be associated with knee OA. The association was observed in LEPR rs1137101 in the present study. In addition, limited data revealed that associations may also exist in ADIPOQ rs2241766, VISFATIN rs4730153 and VISFATIN rs16872158. Prospero registration CRD42020187664.
