Abstract
Methazolamide is a carbonic anhydrase (CA) inhibitor with satisfactory safety. Our previous studies have demonstrated the elevation of CA1 expression and the therapeutic effect of Methazolamide in Ankylosing spondylitis (AS). In this study, we explored the pathogenic role of CA1 and the pharmacological mechanism of Methazolamide in AS through Gene Set Enrichment Analysis (GSEA) and network pharmacology. Seven out of twelve CA1 related gene sets were enriched in AS group. CA1 was core enriched in above seven gene sets involving zinc ion binding, arylesterase activity and one carbon metabolic process. Functional analysis of the candidate target genes obtained from the intersection of AS associated genes and Methazolamide target genes indicated that Methazolamide exerts therapeutic effects on AS mainly through inflammatory pathways which regulate the production of tumor necrosis factor, IL-6 and nitric oxide. PTGS2, ESR1, GSK3β, JAK2, NOS2 and CA1 were selected as therapeutic targets of Methazolamide in AS. Molecular docking and molecular dynamics simulations were performed successfully. In addition, we innovatively obtained the intersection of Gene Ontology (GO)/Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses and GSEA results, and found that 18 GO terms and 5 KEGG terms were indicated in the pharmacological mechanism of Methazolamide in AS, involving bone mineralization, angiogenesis, inflammation, and chemokine signaling pathways. Nevertheless, validation for these mechanisms is needed in vivo/vitro experiments.

Front Endocrinol (Lausanne) 2022; 13:961505. [PMID: 36120439 PMCID: PMC9470850 DOI: 10.3389/fendo.2022.961505] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Accepted: 08/11/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Dyslipidemia is often observed in rheumatic diseases, such as ankylosing spondylitis (AS), rheumatoid arthritis (RA), and systemic lupus erythematosus (SLE), yet it remains to be detected whether rheumatic diseases have a causal effect on dyslipidemia. METHODS Significant (P < 5 × 10-8) and independent (r2 < 0.1) single-nucleotide polymorphisms in genome-wide association studies were selected as instrumental variables to conduct Mendelian randomization (MR) analysis. Inverse variance weighted, weighted median, and MR-Egger regression were adopted for the causal inference. Subsequently, sensitivity analysis was conducted to assess the stability and reliability of MR. RESULTS The MR results revealed positive causal relationships of AS with total cholesterol (TC) (β = 0.089, 95% CI = 0.050 to 0.128, P = 6.07 × 10-6), low-density lipoprotein (LDL) (β = 0.087, 95% CI = 0.047 to 0.127, P = 1.91 × 10-5), and high-density lipoprotein (HDL) (β = 0.043, 95% CI = 0.001 to 0.074, P = 0.009). There was no causal effect of RA on TC (β = 0.008, 95% CI = 4.86 × 10-4 to 0.017, P = 0.064), LDL (β = 6.4 × 10-4, 95% CI = -0.008 to 0.007, P = 0.871), or HDL (β = 0.005, 95% CI = -0.003 to 0.013, P = 0.200). Additionally, SLE had negative causal links for TC (β = -0.025, 95% CI = -0.036 to -0.015, P = 4.42 × 10-6), LDL (β = -0.015, 95% CI = -0.025 to -0.005, P = 0.003), and HDL (β = -0.013, 95% CI = -0.021 to -0.004, P = 0.004). The results were stable and reliable. CONCLUSION This study suggested positive causal effects of AS on TC, LDL, and HDL and negative causal effects of SLE on these cholesterol levels, which could provide much help for the pathogenesis and treatment of rheumatic disease patients with dyslipidemia.

Changes of Metabolic Biomarker Levels upon One-Year Anti-TNF-α Therapy in Rheumatoid Arthritis and Ankylosing Spondylitis: Associations with Vascular Pathophysiology. Biomolecules 2021; 11:biom11101535. [PMID: 34680168 PMCID: PMC8533731 DOI: 10.3390/biom11101535] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 10/15/2021] [Accepted: 10/15/2021] [Indexed: 12/12/2022] Open
Abstract
Background: Cardiovascular (CV) morbidity, mortality, and metabolic syndrome are associated with rheumatoid arthritis (RA) and ankylosing spondylitis (AS). Here, lipids and other metabolic markers in relation to vascular function and clinical markers were evaluated in RA and AS patients undergoing one-year anti-TNF therapy. Patients and methods: Fifty-three patients including 36 RA patients treated with either etanercept (ETN) or certolizumab pegol (CZP) and 17 AS patients treated with ETN were included in a 12-month follow-up study. Various lipids, paraoxonase (PON) and arylesterase (ARE) activities, myeloperoxidase (MPO) and adipokine levels were determined overtime. Ultrasonography was performed to determine flow-mediated vasodilation (FMD), common carotid intima-media thickness (ccIMT), and arterial pulse-wave velocity (PWV) in all patients. All assessments were performed at baseline and 6 and 12 months after treatment initiation. Results: Anti-TNF therapy decreased ARE activity, MPO, adiponectin, and chemerin levels after 12 months (p < 0.05). Lipids, PON activity, and leptin remained unchanged. Regression analyses suggested variable associations of IMT, PWV, and FMD with ARE, MPO, leptin, and lipids (p < 0.05). On the other hand, these metabolic parameters were significantly associated with disease duration, CV history, CRP, obesity, PWV, and IMT (p < 0.05). One-year anti-TNF treatment together with baseline leptin (p = 0.039) or CRP (p = 0.016) levels determined 12 months of lipid changes overtime. TNF inhibition together with baseline disease activity determined ARE activity changes (p = 0.046). Anti-TNF therapy and baseline chemerin levels determined IMT changes overtime (p = 0.003). Conclusions: Assessment of various metabolic parameters together with disease activity, CRP, and ultrasound-based techniques may exert additional value in determining CV burden and in monitoring the effects of biologics on preclinical vascular pathophysiology.

Dynamic thiol-disulfide homeostasis as an oxidative stress marker in ankylosing spondylitis and undifferentiated spondyloarthropathy. Turk J Med Sci 2021; 53:1387-1394. [PMID: 38813044 PMCID: PMC10765557 DOI: 10.55730/1300-0144.5705] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2021] [Revised: 10/26/2023] [Accepted: 04/10/2021] [Indexed: 05/31/2024] Open
Abstract
Background/aim Seronegative spondyloarthropathies (SpA) are a group of chronic diseases characterized by axial inflammation, oligoarthritis, and enthesitis. Oxidative stress may contribute to a wide range of rheumatologic diseases, including SpA. This prospective case-control study was designed to compare thiol-disulfide levels as a marker of oxidative stress between SpA patients and healthy controls. Materials and methods A total of 144 patients diagnosed with undifferentiated spondyloarthropathy (USpA, n = 97) or ankylosing spondylitis (AS, n = 47) were included along with 80 healthy controls. Serum native thiol (NT), total thiol (TT), and disulfide (D) levels were measured using the fully automated Erel method. The ratios NT/TT, D/TT, and D/NT were calculated. Thiol-disulfide levels were compared between the SpA groups and the healthy controls. Results The NT and NT/TT ratios were found to be significantly lower in the SpA group (p < 0.001). The disulfide, D/NT, and D/TT ratios were found to be significantly higher in the SpA group (p < 0.001). In pairwise comparisons between the SpA subgroups, the NT and TT levels were lower in the USpA group than in the AS group (p = 0.021), but serum disulfide levels were higher in the USpA group than in the AS group (p = 0.004). Among the patients with SpA, the group taking antitumor necrosis factor (anti-TNF) had lower TT measurements compared to the group taking conventional disease modifying antirheumatic drugs (DMARD) (p = 0.039). Conclusion The thiol-disulfide balance is disturbed in favor of disulfide in SpA patients compared to healthy volunteers. Native and total thiol measurements correlate with acute phase reactants and might be used to monitor disease activity. Anti-TNF therapy might control the oxidative degenerative process better than the conventional DMARD in SpA patients.

Abstract
The spondyloarthritides are a group of chronic systemic inflammatory joint diseases, the main types being ankylosing spondylitis (AS) and psoriatic arthritis (PsA). Evidence accumulating during the last decades suggests that patients with AS or PsA carry an increased risk for cardiovascular disease and cardiovascular death. This risk appears to be mediated by systemic inflammation over and above classical cardiovascular risk factors. The excess cardiovascular risk in those patients has been formally acknowledged by scientific organizations, which have called physicians' attention to the matter. The application by Rheumatologists of new effective anti-rheumatic treatments and treat-to-target strategies seems to benefit patients from a cardiovascular point of view, as well. However, more data are needed in order to verify whether anti-rheumatic treatments do have an effect on cardiovascular risk and whether there are differences among them in this regard. Most importantly, a higher level of awareness of the cardiovascular risk is needed among patients and healthcare providers, better tools to recognize at-risk patients and, ultimately, commitment to address in parallel both the musculoskeletal and the cardiovascular aspect of the disease.

Abstract
Objective. Ankylosing spondylitis (AS) is a chronic inflammatory disease that affects the axial skeleton, leading to joint disability. Our study aims at investigating the change of oxidative and antioxidative stress linked biomarkers in AS. Methods. This systematic review and meta-analysis was performed following the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) statement. PubMed, Web of Science, and Cochrane Library databases till May 2020 were searched. Only articles published in English were included. Two reviewers screened relevant studies, extracted data, and assessed the quality of included studies using the Newcastle-Ottawa scale independently. Either random or fixed effect model was adopted base on the heterogeneity testing by
statistic. Standardized mean difference (SMD) and 95% confidence intervals (CI) of oxidative and antioxidative markers were calculated.
value <0.05 was considered statistically significant. Results. A total of 22 studies including 931 AS patients and 917 healthy controls met the selection criteria. Significantly increased levels of all oxidative stress markers except myeloperoxidase, and significantly decreased levels of total antioxidant status (
, 95% CI -2.35 to -0.03,
) and paraoxonase 1(
, 95% CI -1.78 to -0.24,
) in serum were observed in AS patients when compared with healthy controls. However, there were no significant differences of all oxidative and anti-oxidative stress biomarkers in erythrocytes. Additionally, the levels of malondialdehyde (
, 95% CI 0.21 to 0.81,
) and advanced oxidation protein products (
, 95% CI 0.58 to 1.31,
) in serum were significantly higher in active patients when compared with inactive AS patients. Conclusion. This meta-analysis demonstrated an overall increase of oxidative markers and decrease of antioxidative markers in AS, suggesting that oxidative stress may play an important role in the pathogenesis of AS.

Abstract
BACKGROUND AND STUDY AIMS The role of oxidative stress in inflammatory bowel disease is increasingly recognised as an important factor. It is assumed that reduced levels of paraoxonase-1 (PON-1) and arylesterase (ARE) may lead to increased inflammation due to increased oxidative stress. This study aimed to investigate the relationship between ARE and PON-1 levels in ulcerative colitis (UC) patients and the difference in these levels in UC patients in comparison to the control group. PATIENTS AND METHODS The study population consisted of 66 (73.3%) UC patients and 24 (26.7%) healthy individuals as the control group. The UC patients and the control group were compared in terms of PON-1 and ARE levels as oxidative stress markers. The UC patients were also grouped according to Mayo UC activity scores, and the differences in their PON-1 and ARE levels were assessed. RESULTS The ARE values were statistically higher in the control group in comparison to the UC patients. Concentrations of PON-1 were not statistically different in the UC and control groups. The ARE value was found to be significantly lower in the UC patients with a haemoglobin level below 10 mg/dl. There was a correlation between the ARE and PON-1 values in the UC patients, but there was no difference between the ARE and PON-1 values, based on the UC patients' Mayo disease severity scores. CONCLUSION This study found that the ARE values of UC patients were lower than those of healthy subjects. The same results could not be determined for PON-1. The data suggest that the antioxidative capacity of UC patients may be reduced.

Abstract
OBJECTIVE Increased reactive oxygen species may play an important role in Ankylosing spondylitis (AS) etiopathogenesis. The thiol group is a very potent antioxidant. In this study, we aimed to investigate the presence of oxidative stress in patients with AS by evaluating thiol/disulfide homeostasis. METHODS In this study, a total of 66 AS patients (27 male, 39 female) and 66 healthy controls (21 male, 45 female) were enrolled. Recently, a novel method for the thiol measurement was found. Thiol and disulfide values were measured by the novel methods. RESULTS Native thiol (NT) (p<0.001) and native thiol/total thiol (NTT) (p<0.001) levels of AS patients were significantly lower compared to the values of the healthy group. However, disulfide (p<0.001), disulfide/native thiol (DNT) (p<0.001) and disulfide/total thiol (DTT) levels of AS patients were a strongly higher control group. A negative correlation was found between BASFI and NTT. Also, a negative correlation was found between BASDAI and NT, NTT levels. A positive correlation was found between BASFI and disulfide, DNT and DTT levels. A positive correlation was found between BASDAI and disulfide, DNT and DTT levels. CONCLUSION The findings revealed that thiol-disulfide homeostasis deteriorated in patients with AS in favor of disulfide amounts. Thiol-disulfide homeostasis can play roles in the etiology and severity of AS.

Abstract
OBJECTIVE To compare the activity of high-density lipoprotein (HDL)-associated paraoxonase 1 (PON1) in patients with psoriasis (PsO) and patients with psoriatic arthritis (PsA), and to evaluate the association of PON1 activity with the extent of disease activity and severity of the cardiovascular disease (CVD) burden in these patients. METHODS Serum levels of paraoxonase and arylesterase activity (both measures of PON1 function in humans) were measured in patients with PsA (n = 198, 51.0% male) and patients with PsO (n = 145, 50.3% male) who were enrolled in a longitudinal psoriatic disease biorepository. Data on PsA disease activity (using the Disease Activity Score in 28 joints [DAS28], Clinical Disease Activity Index, and painful/swollen joint counts), preexistent CVD and CVD risk factors (including diabetes, dyslipidemia, hypertension, and smoking), Framingham Risk Scores for CVD, quality of life measures, and laboratory test findings (erythrocyte sedimentation rate, C-reactive protein level, and lipid profiles) were recorded. RESULTS Serum arylesterase activities were significantly lower in patients with PsO and patients with PsA (mean ± SD 111.1 ± 25.5 μmoles/minute/ml and 124.4 ± 33.4 μmoles/minute/ml, respectively) compared to healthy controls (144.3 ± 33.4 μmoles/minute/ml) (each P < 0.001 versus healthy controls). Serum arylesterase activity decreased in parallel with increasing levels of disease activity (DAS28 scores, P = 0.012), older age (P = 0.013), higher body mass index (P = 0.042), greater incidence of metabolic syndrome (P = 0.004) and hypertension (P = 0.014), and worsening Framingham Risk Scores (P = 0.001). However, no correlation was seen between serum arylesterase activity and the extent of disease activity or CVD burden in patients with PsO. Serum paraoxonase activity trended lower both in patients with PsO and in patients with PsA (each P = 0.073 versus healthy controls). However, no association was seen between serum paraoxonase activity and the extent of disease activity or CVD burden in either of the patient cohorts. CONCLUSION PON1 activity is decreased in psoriatic diseases. In the PsA cohort, decreases in arylesterase activity correlated with increasing severity of joint disease and CVD burden. Arylesterase activity, as compared to paraoxonase activity, appeared to serve as a more sensitive predictor of preexisting CV risk factors in the PsA cohort. However, this correlation was not observed in the PsO population.

Abstract
The aim of this study was to determine the paraoxonase (PON) and arylesterase (ARE) enzyme activity levels in Behcet's disease (BD) and to investigate whether they are associated with the disease activity. Twenty-six patients (study group) with active BD and 28 healthy controls (control group) were included in this study. While the patients who had at least one of the symptoms related to genital ulcer, skin lesions, active uveitis, arthritis, thrombophlebitis, or central nervous system involvement in addition to oral ulcers were considered as the active group, the patients who did not show clinical symptoms in the last one month due to the medical treatment were considered as the inactive group in the clinical evaluation of patients with BD. The PON and ARE levels were found to be significantly lower in the study group than the control group (p < 0.05). The PON levels of the active and inactive groups were 96.23 ± 57.84 and 112.2 ± 65.14, respectively. The ARE levels of the active and inactive groups were 30.49 ± 5.81 and 30.85 ± 6.40, respectively. No significant correlations were found between clinical findings and the activity levels of PON and ARE in the active patient group (p > 0.05). The activities of the antioxidant PON and ARE enzymes are reduced in BD. Therefore, it may be useful to add antioxidant therapy to the conventional treatment of the disease.

Abstract
Objective.Ankylosing spondylitis (AS) is a chronic inflammatory disease associated with increased risk of cardiovascular disease (CVD). High-density lipoprotein (HDL) exerts a series of antiatherogenic properties and protects from CVD. We evaluated whether HDL antiatherogenic properties are impaired in patients with AS.Methods.HDL (apoB-depleted serum) was isolated from 35 patients with AS and 35 age- and sex-matched controls. We measured the antioxidant capacity of HDL, the ability of HDL to induce cholesterol efflux, the activity of HDL-associated enzymes paraoxonase-1 (PON1) and myeloperoxidase (MPO), as well as the ability of HDL to induce Akt kinase activation.Results.HDL from patients with AS had decreased antioxidant capacity and decreased ability to promote cholesterol efflux from macrophages compared to controls. HDL-associated PON1 activity was lower and HDL-associated MPO activity higher in patients with AS compared to controls. Higher MPO activity correlated positively with lower antioxidant capacity of HDL in patients with AS. In addition, HDL from patients with AS had impaired endothelial Akt kinase activating properties that were inversely correlated with the MPO/PON1 ratio and positively correlated with the cholesterol efflux capacity of HDL.Conclusion.HDL from patients with AS displays impaired antiatherogenic properties. Attenuation of HDL properties may constitute a link between AS and CVD.

Abstract
OBJECTIVE To study changes in the nuclear factor-κB p65 (NF-κB p65)-inducible nitric oxide synthase (iNOS)-nitric oxide (NO) signaling pathway and the effects of Xinfeng capsules (XFC) in patients with ankylosing spondylitis (AS). METHODS One hundred twenty patients with AS were randomly divided into an XFC group and a Salazopyrin group. Sixty health subjects were included as a normal control group. In the two treatment groups, pulmonary functional parameters, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), maximal voluntary ventilation (MVV), peak expiratory flow (PEF), forced expiratory flow at 25% of forced vital capacity (FEF25), forced expiratory flow at 50% of forced vital capacity (FEF50), and forced expiratory flow at 75% of forced vital capacity (FEF75) were determined. Enzyme linked immunosorbent assays were used for detection of the serum oxidative stress indexes, NF-κB p65, iNOS, NO, reactive oxygen species (ROS), reactive nitrogen species (RNS), malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), total antioxidative capacity (TAOC) and interleukin-4 (IL-4), IL-10, IL-1β, and tumor necrosis factor-α (TNF-α) contents. Westergren's method was used for determination of erythrocyte sedimentation rate (ESR). High-sensitivity C-reactive protein (Hs-CRP) was detected with a 7060 full-automatic biochemical analyzer (Hitachi, Japan). RESULTS The clinical therapeutic effect in the XFC group was significantly superior to that in the Salazopyrin group (P < 0.01). Compared with the normal control group, FEV1, MVV, PEF, FEF50, FEF75, SOD, CAT, TAOC, IL-4, IL-10 were significantly lower, and NF-κB p65, iNOS, NO, ROS, RNS, MDA, IL-1β, TNF-α, ESR, and Hs-CRP significantly higher in patients with AS (P < 0.01 or P < 0.05). Compared with before treatment, FEV1, MVV, PEF, FEF50, FEF75, SOD, CAT, TAOC, IL-4, and IL-10 were significantly increased, and NF-κB p65, iNOS, NO, ROS, RNS, MDA, IL-1β, TNF-α, ESR, CRP, visual analog scales (VAS), Bath ankylosing spondylitis disease active index, Bath ankylosing spondylitis functional index, and Bath ankylosing spondylitis global index significantly decreased in the two treatment groups after treatment (P <. 0.01 or P < 0.05), with significant differences between the XFC and Salazopyrin groups (P < 0.01 or P < 0.05). Spearman correlation analysis indicated that FEV1, MWVV, PEF, FEF50, and FEF75 were positively correlated with SOD, CAT, TAOC, IL-4, and IL-10, and were negatively correlated with NF-κB p65, iNOS, NO, ROS, RNS, MDA, IL-13, TNF-α, ESR, and CRP. CONCLUSION Patients with AS have local pathologic changes in the spinal cord and other joints. They also have decreased pulmonary function, which is negatively correlated with the NF-κB-iNOS-NO signaling pathway, oxidative indexes, and inflammatory factors. XFC improves rigidity and pain in spinal joints and other symptoms, laboratory indexes, and pulmonary function. The mechanism is possibly related to inhibition of the NF-KB-iNOS-NO signaling pathway.
