Lee S, Yoo JI, Kang YJ. Integrative analyses of genes related to femoral head osteonecrosis: an umbrella review of systematic reviews and meta-analyses of observational studies. J Orthop Surg Res 2022; 17:182. [PMID: 35346283 PMCID: PMC8961967 DOI: 10.1186/s13018-022-03079-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Accepted: 03/16/2022] [Indexed: 11/10/2022] Open
Abstract
Abstract
Background
Femoral head osteonecrosis (FHON) is a worldwide challenging clinical topic. Steroid use is one of the main etiologies of FHON. There are several genetic variants associated with FHON. Therefore, the purpose of this umbrella review was to provide a comprehensive summary of a meta-analysis and systematic review of genetic variations associated with nonsteroidal and steroid-induced FHON.
Methods
The eligible studies were selected from the PubMed and MEDLINE databases for the collection of diverse systematic meta-analyses and reviews. The genetic main effect score was assigned using the Human Genome Epidemiology Network’s Venice criteria to assess the cumulative evidence on the effects of a single nucleotide polymorphism (SNP) on FHON.
Results
Eight articles reported the meta-analysis of candidate SNP-based studies covering eight genes and 13 genetic variants. In the nonsteroid-induced FHON genetic variants including rs2012390 and rs11225394 in MMP8, rs1800629 and rs361525 in tumor necrosis factor (TNF)-α, VNTR in intron 4, rs1799983 and rs2070744 in endothelial nitric oxide synthase (eNOS), rs2010963 in vascular endothelial growth factor (VEGF), and rs6025 in factor V showed significance in each reference. The steroid-induced FHON genetic variants including rs693 and rs1042031 in apolipoprotein (Apo)B, rs1045642 in ABCB1, and rs1799889 in PAI-1 showed significance in each reference.
Conclusion
Based on the systematic review conducted in this study, we organized the genomes associated with FHON and looked at each contribution. Our results could give an integrative approach for understanding the mechanism of FHON etiology. It is expected that these results could contribute to the strategy of prediagnosis, evaluating the individual risk of nonsteroid-induced and steroid-induced FHON.
Level of Evidence: Level I.

Transfus Apher Sci 2020; 60:102967. [PMID: 33059995 DOI: 10.1016/j.transci.2020.102967] [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: 04/02/2020] [Revised: 08/24/2020] [Accepted: 10/05/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Host genetic polymorphisms influence the fibrosis progression of chronic hepatitis C (CHC) patients. Previous studies have shown the association of human platelet antigens (HPAs) polymorphisms with CHC. However, little is known regarding the association of HPAs polymorphisms with the fibrosis progression of CHC. The aim of this study was to determine the association of HPA -2, -3, -5 and -15 polymorphisms with the levels of serum fibrosis marks in CHC patients. METHODS The HPA -2, -3, -5 and -15 were genotyped by 5'-nuclease assay in 211 CHC patients, while the serum concentration of hyaluronic acid (HA), collagen IV (CIV), amino-terminal pro-peptide of type III procollagen (PIIINP), and laminin (LN) from the same samples were measured by time resolved fluorescence immunoassay. RESULTS The level of serum LN was significantly lower in CHC patients with HPA-15aa genotype compared to those with HPA-15ab/bb (P = 0.032) but did not differ among HPA-2, -3 and -5 genotypes. There were no difference in HA, CIV and PIIINP levels among HPA-2, -3,-5 and -15 genotypes. CONCLUSIONS This study demonstrates that HPA-15 aa polymorphism is associated lower serum LN in CHC, which suggests that HPA -15 aa may be involved in the fibrosis progression of CHC.

Abstract
Osteonecrosis of the femoral head (ONFH) usually occurs in young people and is closely associated with autoimmune reactions. Follistatin-like 1 (FSTL1) was recently proven to participate in several inflammation-related diseases. The role of FSTL1 in ONFH is still unclear. Serum levels of FSTL1 were not significantly different in ONFH patients and healthy individuals. In contrast, elevated expression levels of FSTL1 were observed in degraded cartilage and synovial fluid in ONFH patients and in a cultured human primary chondrocyte model treated with interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α). Suppression of FSTL1 by FSTL1-siRNA downregulated the inflammatory response mediated by IL-1β or TNF-α in cultured human chondrocytes. In a human cartilage culture model, FSTL1 promoted the production of inflammatory cytokines and cartilage degradation enzymes. The activation of NFκB signaling pathway was detected in degenerated cartilage from ONFH patients and in FSTL1-treated chondrocytes. Additionally, administration of an NFκB inhibitor (JSH-23) significantly reduced the overexpression of inflammatory cytokines and protein degradation enzymes induced by FSTL1 and maintained the level of major cartilage matrix components (aggrecan and collagen II). In summary, FSTL1 was involved in the degeneration progression of the ONFH and might provide a novel direction for treating and curing ONFH.

Abstract
PURPOSE The association between TNF-α-308(G/A) and -238(G/A) polymorphisms and the susceptibility of non-traumatic osteonecrosis of the femoral head (NONFH) was investigated in many studies with conflicting results. We aimed to conduct a meta-analysis to evaluate the relationship between them comprehensively. METHODS Relevant literatures published in PubMed, Web of Science, Embase, Cochrane library databases, China National Knowledge Infrastructure (CNKI), WANFANG Data, and China Science and Technology Journal Database (CSTJ) updated to January 30, 2018, were reviewed by two investigators independently. Odds ratios (ORs) and its 95% confidence intervals (95% CIs) were calculated by a fixed-effect model based on the indistinctive heterogeneity. RESULTS For TNF-α-308(G/A) polymorphism, we recruited five studies including 432 NONFH patients and 760 controls and a statistically significant association was identified in Asians in four modes consisting of alleles mode (OR = 0.648, 95% CI 0.475-0.885), homozygote mode (OR = 0.330, 95% CI 0.136-0.802), dominant mode (OR = 0.344, 95% CI 0.143-0.827), and recessive mode (OR = 0.674, 95% CI 0.468-0.971), but no significant association was observed in Caucasians. For TNF-α-238(G/A) polymorphism, three eligible studies including 275 cases and 610 controls were evaluated and there was a significant association in alleles mode (OR = 0.270, 95% CI 0.4148-0.490) as well as recessive mode (OR = 0.254, 95% CI 0.138-0.468). CONCLUSION This meta-analysis shows that TNF-α-308(G/A) and -238(G/A) polymorphisms are associated with the susceptibility of NONFH, while the significant association for 308(G/A) is mainly observed in Asians.

Abstract
BACKGROUND Nephrotic syndrome (NS) characterized by complex pathogenesis and clinical course with relapses; and needs novel breakthroughs for decades. Polymorphisms of cytokines genes including tumor necrosis factor alpha (TNF-α)may influence susceptibility to NS as well as different patients' steroid responses. In the current study, we demonstrated the potential roles of TNF-α promoter gene polymorphisms [-238, -308, -863] and haplotypes in susceptibility to childhood NS. Also, elucidating their possible influence on patients' steroid response and serum TNF-α level. METHODS This case-control study included 150 children suffering from NS and 150 healthy children. Polymerase chain reaction- restriction-fragment length polymorphism (PCR-RFLP) was performed to evaluate different TNF-α gene polymorphism. TNF-α serum levels were assessed by ELISA. RESULTS Serum TNF-α levels were significantly higher in NS patients than in controls and in steroid resistant NS (SRNS) than in steroid sensitive NS (SSNS) (P<0.001 for each). The risk of NS in patients carrying TNF-α-238GA genotype, and TNF-α-308GA or AA genotypes and allele A was significantly increased compared to healthy children. While no significant association was detected between TNF-α-863 and NS. The risk of resistance to steroid therapy was significantly high in NS carrying TNF-α-238GA genotype and A allele, TNF-α-308, AA genotypes and A allele, and TNF-α-863CA, AA genotypes and A allele. The TNF-α GCG (-308/-863/-238) haplotype has protective roles against NS and steroid resistance. However, the risk of NS was significantly high in TNF-α AAG and AAA haplotype's carriers compared to healthy children. Additionally the risk of steroid resistance was significantly high in TNF-α AAA haplotype's NS carrier (OR (95%CI): 2.2 (1.19-4.36), P=0.01). Moreover, we found significant higher serum TNF-α levels NS patients including SSNS and SRNS carrying mutant allele TNF-α-238GA genotype, -308GA and AA and -863CA and AA wild genotype's carriers than in those GG, GG and CC respectively. Interstingely, TNF-α levels were significantly higher in healthy children carrying TNF-α(-308/-863/-238) [AAG and AAA haplotypes], NS cases carrying [ACA, AAG, AAA haplotypes], and in SSNS carrying [ACA and AAA haplotypes] than in those carrying GCG, haplotype of wild alleles. CONCLUSION This study reported, for the first time, that TNF-α promoter gene polymorphisms and/or haplotypes are risk factors of NS and resistance to steroid among Egyptian children.

Abstract
Hepatic fibrosis may be the result of repetitive injury to hepatocytes caused by HCV infection and the immune response to it. Cytokines regulate the inflammatory response to injury and modulate hepatic fibrogenesis. Single nucleotide polymorphisms (SNPs) located in cytokine genes may influence the cytokine expression and secretion that may contribute to hepatic fibrogenesis in HCV infection. The aim of this study was to determine the genotype of 22 SNPs found in the genes of 13 cytokines/cytokine receptors to assess the influence of polymorphic variants on the stage of liver damage in Brazilian patients chronically infected with HCV genotype 1 only. 141 unrelated patients were grouped according to their stage of fibrosis: absence of fibrosis or patients in the initial stages of fibrosis (F0-F2, n = 84), patients with advanced stages of fibrosis or cirrhosis (F3-F4, n = 57), without cirrhosis (F0-F3, n = 103), and with cirrhosis (F4, n = 38). The comparison of frequencies in each sub-sample was performed by 2 × 2 contingency tables using the chi-square or Fisher's exact test. Stepwise logistic regression was also used to assess independent associations between cirrhosis or fibrosis with polymorphic variants. The TNFA-308G:A genotype conferred increased risk of fibrosis and cirrhosis. The TNFA-238G:G genotype was associated with protection from cirrhosis. The IL10-819C:T genotype conferred protection from fibrosis and the IL1B-511C:T genotype conferred increased risk of cirrhosis. Some of these genotypes showed results on the borderline of statistical significance in the bivariate analysis. We conclude that gene variants of cytokines/receptors may influence liver damage in patients chronically infected by HCV genotype 1.

Abstract
OBJECTIVE Analysis of the contribution of genetic (single nucleotide polymorphisms (SNP) at position -238 and -308 of the tumor necrosis factor alpha (TNF-α) and -592 of the interleukin-10 (IL-10) promotor genes) and of classical factors (age, alcohol, immunodepression, antirretroviral therapy) on the risk of liver cirrhosis in human immunodeficiency (HIV)-hepatitis C (HCV) virus coinfected patients. PATIENTS AND METHODS Ninety one HIV-HCV coinfected patients (50 of them with chronic hepatitis and 41 with liver cirrhosis) and 55 healthy controls were studied. Demographic, risk factors for the HIV-HCV infection, HIV-related (CD4+ T cell count, antiretroviral therapy, HIV viral load) and HCV-related (serum ALT concentration, HCV viral load, HCV genotype) characteristics and polymorphisms at position -238 and -308 of the tumor necrosis factor alfa (TNF- α) and -592 of the interleukin-10 (IL-10) promotor genes were studied. RESULTS Evolution time of the infection was 21 years in both patients' groups (chronic hepatitis and liver cirrhosis). The group of patients with liver cirrhosis shows a lower CD4+ T cell count at the inclusion in the study (but not at diagnosis of HIV infection), a higher percentage of individuals with previous alcohol abuse, and a higher proportion of patients with the genotype GG at position -238 of the TNF-α promotor gene; polymorphism at -592 of the IL-10 promotor gene approaches to statistical significance. Serum concentrations of profibrogenic transforming growth factor beta1 were significantly higher in healthy controls with genotype GG at -238 TNF-α promotor gene. The linear regression analysis demonstrates that the genotype GG at -238 TNF-α promotor gene was the independent factor associated to liver cirrhosis. CONCLUSION It is stressed the importance of immunogenetic factors (TNF-α polymorphism at -238 position), above other factors previously accepted (age, gender, alcohol, immunodepression), on the evolution to liver cirrhosis among HIV-infected patients with established chronic HCV infections.

Abstract
BACKGROUND Both interleukin-28B genetic variants and on-treatment virological responses are factors predictive of treatment outcome in hepatitis C virus genotype 1 (HCV-1) patients. We aimed to compare the clinical significance of the two factors. METHODS Rs8099917 genotype and on-treatment responses were determined in 182 HCV-1 patients with 48-week peginterferon/ribavirin. RESULTS Comparing to patients with rs8099917 TG/GG genotype, those with TT genotype had significantly higher rapid virological response (RVR, 46.2% vs. 19.2%, P=0.01) and sustained virological response (SVR, 85.3% vs. 42.3%, P<0.001) rates. Logistic regression analysis revealed that the strongest factor predictive of a RVR was the carriage of rs8099917 TT genotype (odds ratio/95% confidence intervals [OR/CI]: 4.25/1.39-13.01). The most important factor predictive of an SVR was the attainment of a RVR (OR/CI: 57.22/6.23-525.37), followed by the carriage of rs8099917 TT genotype (OR/CI: 10.06/3.12-32.44). However, while on-treatment factors were taken into account, the cEVR was the most important determinant to an SVR (OR/CI:54.98/9.07-333.38), whereas the influence of rs8099917 genotype became non-significant in non-RVR patients. CONCLUSIONS Rs8099917 TT genotype is significantly independently predictive of on-treatment virological responses, which were the major determinants of an SVR, in Asian HCV-1 patients.

Abstract
Toll-like receptors (TLRs) are an important part of the innate immune response to a variety of pathogens including hepatic viral infections. Activation of TLRs stimulates a complex intracellular signalling cascade that results in production of proinflammatory cytokines and interferons important for antiviral responses as well as induction of the adaptive arm of the immune system. There is substantial evidence for an important role for TLRs and TLR-mediated signalling in the pathogenesis and outcomes of hepatitis B and C in particular, but it might also influence responses to other viral hepatitis infections. Several single nucleotide polymorphisms (SNPs) of TLRs, relevant adaptor molecules and cytokines mediated by TLR signalling have been described that alter innate immune responses and have been implicated in a variety of human diseases including viral and other infections. There is now significant evidence that a number of TLR SNPs can affect various clinical outcomes in Caucasian patients with chronic HCV. However, the role of these polymorphisms in acute and other chronic hepatitis infections, including HBV as well as in non-Caucasian populations, has not been elucidated. In addition, results for SNPs downstream of TLR activation, such as in relevant cytokines, are inconsistent and their influence requires further investigation to determine the clinical significance of genetic variations in these mediators.

Dysfunction of Immune Systems and Host Genetic Factors in Hepatitis C Virus Infection with Persistent Normal ALT. HEPATITIS RESEARCH AND TREATMENT 2011; 2011:713216. [PMID: 21760997 PMCID: PMC3132496 DOI: 10.1155/2011/713216] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/02/2011] [Accepted: 04/15/2011] [Indexed: 12/24/2022]
Abstract
Patients with chronic hepatitis C (CHC) virus infection who have persistently normal alanine aminotransferase levels (PNALT) have mild inflammation and fibrosis in comparison to those with elevated ALT levels. The cellular immune responses to HCV are mainly responsible for viral clearance and the disease pathogenesis during infection. However, since the innate and adaptive immune systems are suppressed by various kinds of mechanisms in CHC patients, the immunopathogenesis of CHC patients with PNALT is still unclear. In this review, we summarize the representative reports about the immune suppression in CHC to better understand the immunopathogenesis of PNALT. Then, we summarize and speculate on the immunological aspects of PNALT including innate and adaptive immune systems and genetic polymorphisms of HLA and cytokines.

Abstract
Hepatitis C virus contact and infection show three different phenotypes: spontaneous viral clearance (SVC), chronic hepatitis C (CHC) and sustained virological response (SVR) following antiviral treatment. Many factors, including genetics, influence the evolution of these three phenotypes. We performed a literature search (PubMed) up to 31 January 2010 without language restriction to identify relevant studies on genes and hepatitis C. Additional studies were sought by reviewing the reference lists of the identified articles. Meta-analysis (using Meta-disk 1.4) was conducted to evaluate the association of single nucleotide polymorphism (SNP) in the IL28B region and SVR. The candidate gene approach showed strong relationships between human leucocyte antigen class II (DQB1(*) 0301 and DRB1(*) 1101) and SVC. A cirrhosis risk score involving 7 SNPs has been validated recently. The set of odds ratios of studies demonstrated an association between SNP (rs12987960/rs8099917) in the IL28B and SVR in CHC treated with peginterferon plus ribavirin (OR: 4.6; 95% CI: 2.9-7.3). The overall distribution of protective allele correlated with ethnic differences in SVR (Asians, Europeans, Hispanic and Afro-Americans) together with SVC, but not with fibrosis stage or viral load. These polymorphisms did not influence SVR in very-easy-to-treat patients such as genotype 2/3, rapid virological responders or patients with acute hepatitis C. While the genetic fingerprint for fibrosis progression remains elusive, IL28b polymorphism predicts SVC and SVR. However, nearly half of patients achieving SVR did not show favourable genotype. Further genetic signals are warranted to complete the puzzle of factors influencing hepatitis C.

Combined effect of pro- and anti-inflammatory cytokine gene polymorphisms on susceptibility to liver cirrhosis in Tunisian HCV-infected patients. Hepatol Int 2011; 5:681-7.

Abstract
PURPOSE Chronic hepatitis C progression is commonly attributed to the continuous activation of the immune response with an increased production of pro-inflammatory cytokines, leading to fibrosis and ultimately to cirrhosis. On the contrary, anti-inflammatory cytokines, mainly interleukin (IL)-10 have a modulatory effect on hepatic fibrogenesis. The association between individual polymorphisms within cytokine genes and hepatitis C outcome is often weak and non-informative. Interestingly, it has been demonstrated that a combination of specific genotypes may be a more significant and powerful approach for predicting disease risk. AIM This study is aimed at investigating the combined effect of single nucleotide polymorphism (SNP) in IL-18 (-607C/A, -137G/C), interferon (IFN)-γ (+874T/A) and IL-10 (-1082G/A) genes on cirrhosis risk in HCV-infected patients. METHODS Seventy-seven chronic hepatitis C Tunisian subjects were included in this study. The patients were divided into two groups: the first included 31 non-cirrhotic patients, and the second included 46 liver cirrhosis patients. IL-18 genotyping was performed using the PCR amplification and the restriction fragment length polymorphism analysis (RFLP). IFN-γ and IL-10 polymorphisms were analyzed using the allele-specific PCR (AS-PCR). RESULTS The combined high-risk genotype (IL-18 -607C/*, IL-18 -137G/*, IFN-γ +874T/*, IL-10 -1082A/A) frequency was compared between patients with and those without cirrhosis. Individuals were classified according the number of high-risk genotypes as follows: (0-2), patients with at most two high-risk genotypes; (3-4), patients with at least three of the high-risk genotypes. The logistic regression analysis showed that patients harboring 3-4 putative high-risk genotypes have a fivefold higher risk for developing cirrhosis in comparison to those harboring at most two high-risk genotypes (OR = 5.19; 95% CI = 1.49-18.05; p = 0.009). CONCLUSION Our study showed that the co-inheritance of IL-18, IFN-γ and IL-10 specific high-risk genotypes is associated with a greater risk for liver cirrhosis.

Abstract
The production of transforming growth factor beta 1 (TGF-beta1) has been reported as being significantly associated with the gene polymorphism in the leader sequence at positions +29. The current study aimed to evaluate the associations between the polymorphism and the clinical characteristics of chronic hepatitis C (CHC). A total of 422 (252 men; mean age: 49.7 +/- 11.2 years) Taiwanese CHC patients with liver biopsies were enrolled. The TGF-beta1 gene polymorphism at position +29 (T or C), hepatitis C virus (HCV) RNA genotypes, and serum HCV RNA levels of these patients were determined. Of the 422 patients, the frequency of the T allele was 45.4%. Based on univariate analyses, a significantly lesser proportion of patients with allele T had high viral loads than those who were without allele T (P = 0.026). The lesser HCV RNA levels and HCV genotype 1b infection were significantly associated with the inheritance of the T allele in female patients based on univariate (P = 0.012 and 0.007, respectively) and multivariate regression (odds ratio/95% confidence interval: 0.434/0.219-0.859 and 0.468/0.237-0.927, respectively) analyses. In male patients with or without inheritance of the T allele, the clinical characteristics were similar. In conclusion, the association between TGF-beta1 polymorphism and virologic characteristics of chronic HCV infection implicated a significant role of host genetic factors on the clinical features of CHC. Female patients who carry T allele at position +29 were predisposed to be associated with HCV genotype non-1b infection and lesser HCV viral load, which revealed the gender effect.

Abstract
Epidemiological evidence clearly identifies chronic infection with hepatitis C virus (HCV) as a major risk factor for the development of hepatocellular carcinoma (HCC). Among the mechanisms that have been implicated in the pro-carcinogenic effect of HCV infection, an increased production of reactive oxygen species in the liver seems to have a major pathogenetic role in leading from chronic inflammation to cancer. Recent data have also demonstrated that HCV is capable of inducing this active production of free radicals per se, not just through inflammation, a feature peculiar to this virus and the specific activity of its core protein. This paper provides an overview of the inter-relationships between HCV, liver damage, free radical production and HCC, describing at least in part the complex network involving DNA oxidative damage, cytokine synthesis, proto-oncogene activation and oestrogen receptor expression, that may all be deeply involved in liver carcinogenesis.
