High plasma homocysteine level is associated with increased prevalence of the non-remission state in rheumatoid arthritis: Findings from the KURAMA cohort. Mod Rheumatol 2023; 33:911-917. [PMID: 36069659 DOI: 10.1093/mr/roac106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 07/28/2022] [Accepted: 08/31/2022] [Indexed: 11/13/2022]
Abstract
OBJECTIVES We aimed to determine the clinical impact of plasma homocysteine levels on disease activity and clinical remission in patients with rheumatoid arthritis (RA). METHODS A cross-sectional study was conducted using KURAMA (Kyoto University Rheumatoid Arthritis Management Alliance) database. We enrolled 291 female patients, who were treated in a treat-to-target manner. We measured plasma total homocysteine using a liquid chromatography-tandem mass spectrometry system and collected clinical data including a 28-joint RA disease activity score-erythrocyte sedimentation rate (DAS28-ESR). Clinical remission of disease activity was defined as a DAS28-ESR < 2.6. RESULTS In a univariable analysis, the plasma homocysteine concentration was significantly and positively associated with DAS-28-ESR and was higher in the non-remission group than in the remission group. The cutoff value of the plasma homocysteine level was calculated to be 7.9 nmol/mL by the test of the receiver operating characteristic curve analysis. In a multivariable analysis, after adjusting for clinically relevant variables, the high homocysteine level remained a significant positive association for DAS28-ESR (estimate 0.27, P = .0019) and a positive factor for the presence of RA non-remission (odds ratio 2.39, P = .0071). CONCLUSIONS Increased plasma homocysteine levels showed a significant positive association with current disease activity and the non-remission state in female patients with RA under treat-to-target treatment. The findings suggest the potential utility of plasma homocysteine as a disease state marker reflecting conditions that are treatment failure and difficult to remission and may provide clinical evidence on the interplay between homocysteine and inflammatory activation in RA.

Abstract
BACKGROUND: It has been reported that the quality of life and diet quality in individuals with rheumatological diseases are poor and may adversely affect the course of the disease. OBJECTIVE: This study aims to compare the quality of life and diet of individuals with Behçet’s Disease (BD) compared to healthy controls. METHODS: This study was planned as a case-control study, and 60 adult patients with BD were compared with age (±1) and sex paired match healthy controls concerning the quality of life and diet. Diet quality was assessed using nutrient adequacy ratio (NAR) and the mean adequacy ratio (MAR) values calculated from 24 h dietary food recall and obesity was also evaluated by various anthropometric measurements. The Short Form-36 Health Survey (SF-36) was used to evaluate the quality of life (QoL). In addition, the 24-hour physical activities were recorded to calculate physical activity levels (PAL). Data were analyzed by SPSS 25.0 via paired sample t-test and McNemar (and McNemar-Bowkers) test. p < 0.05 was deemed significant. RESULTS: The findings showed that cases were more obese (p = 0.005), less physically active (p < 0.001), had lower QoL (p < 0.01 for all subscales) and had higher Beck depression scores (p = 0.001). Controls had higher means of energy (p < 0.001), CHO% (p = 0.025), fat% (p = 0.004), and fiber (p = 0.007) intake and mean MAR value (p < 0.001). CONCLUSIONS: Compared to healthy controls, patients with BD were more obese, had lower QoL and lower diet quality. Therefore, people with BD should be evaluated for comorbid diseases and be supported by health professionals, such as dietitians and psychologists.

Abstract
AIM To evaluate the relevance of plasma homocysteine (HC) in Behcet's disease (BD) and its clinical manifestations. METHODS Systematic review of EMBASE and PubMed databases according to PRISMA guidelines from inception to July 2021; random-effects meta-analyses for continuous outcomes. RESULTS The search strategy retrieved 48 case-control (2,669 BD and 2,245 control participants) and 5 cohort studies (708 BD participants). Plasma HC was higher in BD than in controls (p < 0.0001) with wide heterogeneity (I2 = 89.7%) that remained unchanged after sensitivity analysis according to year of article publication, age of BD participants, study size, study quality, method of HC determination, and male/female ratio >1.5; some pooled ethnicities explained a small part of the heterogeneity (I2 = 16.3%). Active BD participants had higher HC than inactive ones (p < 0.0001), with moderate heterogeneity (I2 = 49.2%) that disappeared after removal of an outlier study with very high disease activity. BD participants with any vascular involvement had higher HC than those without (p < 0.0001) with wide heterogeneity (I2 = 89.7%); subgroup analysis on venous thrombosis only changed neither effect size (p < 0.0001) nor heterogeneity (I2 = 72.7%). BD participants with ocular involvement had higher HC than those without (p < 0.0001) with moderate heterogeneity (I2 = 40.3%). CONCLUSION Although causality cannot be inferred, the consistency of the elevation of plasma HC in BD, particularly in patients with active disease, with vascular and ocular involvement suggests an intrinsic involvement of HC in these clinical manifestations.

Abstract
Epidemiological studies conducted over the past 25 years have provided ample support for the association of mild hyperhomocysteinemia (HHcy) with an elevated risk of atherothrombosis. Since autoimmune disorders (AD) are frequently associated with relevant and early signs of atherothrombotic damage not adequately explained by the traditional risk factors involved in the onset of cardiovascular disease (CVD), a large interest has been shown to the putative role of mild HHcy in this setting. On the basis of such considerations, we focused the attention on the relationship between homocysteine (Hcy) and CVD in patients affected with autoimmune diseases, reviewing the most recent literature data and also providing our original experience. Although the large amount of available studies clearly shows that HHcy represents a common finding in patients affected with several autoimmune diseases, the actual role of Hcy in the development of CVD in the course of AD is not clear yet, perhaps, with the only exception of the systemic lupus erythematosus. In the other conditions, the role of Hcy in the pathogenesis of vascular complications is still a matter of debate, as the result of conflicting reports and/or lack of an adequate body of investigation.

Abstract
OBJECTIVES To evaluate the serum homocysteine (Hcy) and leptin levels in patients with uveitis. MATERIALS AND METHODS The 70 cases included in the study comprised 3 groups: patients with Behçet's uveitis (BU), patients with non-Behçet's uveitis (NBU) and healthy controls. Body mass index was calculated for each subject. Serum Hcy and leptin levels were measured. Furthermore, acute-phase reactants including erythrocyte sedimentation rate (ESR), C-reactive protein and neutrophil count were measured. RESULTS Serum Hcy levels were 15.04±4.59 µmol/L in the BU group, 15.4±6.87 µmol/L in the NBU group and 13.64±4.72 µmol/L in the control group (p>0.05). The serum leptin levels of male patients in the BU group, NBU group and control group were 4.76±3.54 ng/ml, 6.33±3.74 ng/ml and 5.47±6.33 ng/ml, respectively (p>0.05). When we compared serum leptin levels in female patients and controls, the mean serum leptin concentrations were significantly higher in female BU and NBU patients (24.83±17.62 ng/ml and 28.46±13.90 ng/ml, respectively) than in healthy control volunteers (9.62±6.36 ng/ml, p<0.05). In addition, the ESR value differences between groups were statistically significant (p<0.05). CONCLUSION A larger case series is necessary to investigate serum Hcy and leptin concentrations in uveitis patients.

Abstract
C3 is the central component of the complement system and activation of C3 via any of the three major activation pathways-the classical, the lectin and the alternative pathways-results in initiation of the terminal complement pathway and release of the anaphylatoxin C3a. Both terminal pathway activation and signalling of C3a and its inactivation product C3a-desarg via the C3a receptor and C5a-like receptor 2, respectively, can induce inflammatory, immunomodulatory and metabolic responses. C3 has been implicated in metabolic disorders, notably adiposity, dyslipidaemia, insulin resistance, liver dysfunction and diabetes, and C3 is increasingly recognised as a cardiometabolic risk factor. C3 may play a role in the macrovascular, as well as microvascular, complications of diabetes. Moreover, C3 may interact with the coagulation system and as such also contribute to a procoagulant, hypofibrinolytic and, ultimately, prothrombotic state. Recent data suggest a diabetes-dependent incorporation of C3 into fibrin clots, with concomitant effects on clot characteristics. Taken together, epidemiological and experimental evidence concordantly point to a role of complement C3 in metabolic, atherosclerotic/atherothrombotic and microangiopathic processes and further research should be directed towards the elucidation of complement function and activation in cardiometabolic disorders.

Abstract
PURPOSE OF REVIEW To alert physician to timely recognition and current treatment of recurrent hypopyon iridocyclitis or panuveitis in ocular Behçet disease (OBD). RECENT FINDINGS Interferon-α, rituximab, intravitreal triamcinolone, and biological response modifiers by tumor necrosis factor inhibitors such as infliximab and adalimumab are being used increasingly for the treatment of severe sight-threatening ocular inflammation including retinal vasculitis and cystoid macular edema (CME). SUMMARY Biological agents offer tremendous potential in the treatment of OBD. Given that OBD predominantly afflicts the younger adults in their most productive years, dermatologist, rheumatologist, internist, or general practitioners supervising patients with oculo-articulo-oromucocutaneous syndromes should be aware of systemic Behçet disease. Early recognition of ocular involvement is important and such patients should strongly be instructed to visit immediately an ophthalmologist, as uveitis management differs from extraocular involvements with high ocular morbidity from sight-threatening complications due to relapsing inflammatory attacks in the posterior segment of the eye. A single infliximab infusion should be considered for the control of acute panuveitis, whereas repeated long-term infliximab infusions were proved to be more effective in reducing the number of episodes in refractory uveoretinitis with faster regression and complete remission of CME.

Abstract
Objectives. The aim of this study was to investigate if hyperhomocysteinaemia is a contributive risk factor for the pathogenesis and the activity of Behçet's disease (BD). Design and Methods. Fifty four patients fullfiling the criteria of the International Study Group for BD were enrolled. Fifty healthy volunteers matched for age and sex with the BD group were included as a negative control group. Patients, with any condition that might affect plasma homocysteine concentration, were excluded. Results. Mean serum homocysteine concentration was significantly higher in patients with BD than in the healthy controls (P < .001), in patients with active disease (P = .04), and in masculine gender (P = .05). There was no significant difference between homocysteine level and clinical involvement. Conclusions. We demonstrated that plasma total homocysteine level (tHcy) is increased in BD and correlated with disease activity. No association was found between homocysteine levels and clinical involvement.

Abstract
OBJECTIVE Behçet disease (BD) is a vasculitis of unknown etiology, characterized by oral or genital aphtosis and uveitis. Homocysteine (hcy) is an independent risk factor for venous and arterial thrombosis. The association between hyperhomocysteinemia and thrombosis has been investigated in some studies in BD patients. However, information on this association is based only on the results of small studies with conflicting results. To overcome such limitations, we performed a metaanalysis comparing the plasma levels of hcy in BD patients with and without history of thrombosis. METHODS AND RESULTS We searched for all published studies using the Medline and Embase databases. Two reviewers performed study selection independently. Studies were included if hcy was measured in adult BD patients with and without thrombosis. Two reviewers independently extracted data on study and population characteristics. The mean value of hcy in BD patients and the presence of hyperhomocysteinemia in patients with and without thrombosis were collected. Association between thrombosis and hyperhomocysteinemia, and the mean difference of hcy levels in BD patients with and without thrombosis were calculated. Sixteen studies, for a total of 979 patients, were included. Hyperhomocysteinemia was more prevalent in patients with thrombosis than in those without (odds ratio 3.14; 95% CI 1.26 to 7.80) Mean levels of hcy were significantly higher in patients with thrombosis in comparison with patients without (mean difference 3.30 μmol/L; 95% CI 2.09 to 4.51). CONCLUSIONS Our results suggest that hyperhomocysteinemia may be considered to be associated with thrombosis in BD patients.

Abstract
The mechanism for vascular involvement of Behçet disease (BD) includes arterial and venous thrombosis. Although the exact etiology of systemic vasculitis and thrombosis is still unknown, many hypotheses have been suggested. One of these hypotheses is that hyperhomocysteinemia causes vascular disease and thrombosis. The aim of this study was to compare the levels of homocysteine, vitamin B(12), and folic acid of BD patients with those of recurrent aphthous stomatitis (RAS) patients and healthy controls. Forty-five BD patients, 47 RAS patients, and 69 healty control subjects were included in this study. Vitamin B(12), folic acid, and homocysteine levels of the patients and controls were measured, and statistical differences among the groups were determined. BD patients had mostly cutaneous symptoms. Arthritis and ocular and vascular involvement were seen in 24.4%, 22%, and 11% of BD patients, respectively. No significant difference was detected among the groups in the levels of vitamin B(12), folic acid, and homocysteine. There was no significant difference in any parameters according to sex and age of the patients and activity of BD and if the patients with BD were treated or not. Homocysteine level inversely correlated with vitamin B(12) and folic acid levels in the BD group. We could not find any differences in homocysteine, vitamin B(12), and folic acid levels between BD and RAS patients and controls. This may be due to the fact that our patients mostly had cutaneous symptoms rather than vascular involvement.

[PMID: 19197380 PMCID: PMC2633607 DOI: 10.1155/2008/407972] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2008] [Revised: 11/02/2008] [Accepted: 11/17/2008] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVE Our aim was to evaluate the significance of homocysteine (Hcy) in Behcet's disease (BD) and the association of elevated Hcy levels associated with the indices of inflammation in BD. METHODS Untreated 70 patients with BD and 33 healthy individuals were included into the study. Hcy, tumor necrosis alpha (TNF-alpha), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were evaluated with respect to activity and specific individual clinical manifestations of the disease. RESULTS Hcy levels were found significantly elevated in active BD when compared to inactive BD and healthy controls. Hcy levels were found to have high correlation with the number of active clinical manifestations increased. A significant positive correlation was found between serum Hcy and TNF-alpha levels, CRP, and ESR. Hcy was found to be the best predictor of TNF-alpha among other parameters. CONCLUSION Hcy may involve in the pathogenesis of BD by inducing inflammation.

Abstract
Hyperhomocysteinemia is independently associated with the development of coronary, cerebral and peripheral vascular disease and deep-vein thrombosis in the general population. The evidence that cardiovascular involvement is particularly frequent and advanced in patients affected with several autoimmune diseases (AD), in which hyperhomocysteinemia represent a common finding, led to an intensive investigation on homocysteine (Hcy) as a putative risk factor for the development of cardiovascular disease in such subjects. Indeed, recent data intriguingly expanded the spectrum of the possible pathogenetic implications for hyperhomocysteinemia in the course of AD. In fact, a bi-directional link seems to connect Hcy and the immuno-inflammatory activation characterizing AD, in which immuno-inflammatory activation may contribute to Hcy increase, and Hcy, in its turn, may act as a pro-inflammatory and immuno-stimulating molecule putatively cooperating to the injury of the disease-specific target organs, at least in rheumatoid arthritis and inflammatory bowel disease. Moreover, Hcy may be also a trigger of autoimmune reactions through its capability to bind and structurally modify specific proteins, then resulting in neoantigens formation potentially relevant either in the onset of specific AD and in the progression of the associated cardiovascular damage. More investigation is necessary to fully define the clinical relevance of such phenomena.

Abstract
BACKGROUND Behçet's disease is a multisystemic immunoinflammatory disease with a wide variety of clinical manifestations, whereas recurrent aphthous stomatitis is a local oral disease. The aim of this study was to examine the distribution of homocysteine levels in patients with active Behçet's disease, possible association of homocysteine with nitric oxide and neopterin levels, and to characterize the differences between patients with Behçet's disease and those with recurrent aphthous stomatitis in terms of these parameters compared with healthy controls. METHODS A total of 23 patients with active Behçet's disease, 25 patients with recurrent aphthous stomatitis as positive controls, and 21 healthy subjects were included in this study. Serum homocysteine and neopterin levels were measured flourimetrically by HPLC. Serum nitric oxide production was assayed by measuring total nitrite levels with Griess reagent. RESULTS Significantly higher homocysteine (12.9+/-3.3 micromol/L) and lower nitric oxide (41.5+/-10.9 micromol/L) and neopterin (6.4+/-1.0 nmol/L) levels were observed in patients with Behçet's disease compared with healthy controls (10.7+/-2.0 micromol/L, 49.7+/-16.2 micromol/L, 8.7+/-2.2 nmol/L, respectively) (p<0.03 for neopterin, p<0.04 for homocysteine and nitric oxide). However, homocysteine, nitric oxide, biopterin and neopterin levels and the neopterin/biopterin ratio for recurrent aphthous stomatitis patients were not significantly different compared to healthy controls. A significant positive correlation was observed between serum homocysteine and serum neopterin/biopterin ratio in patients with Behçet's disease (r=0.975, p<0.005). CONCLUSIONS In contrast to recurrent aphthous stomatitis, there is a higher prevalence of hyperhomocysteinemia in Behcet's disease. Homocysteine may have deleterious effects on the pathology of Behcet's disease by decreasing nitric oxide levels and interfering with the immune system.

Abstract
Survival of patients with systemic lupus erythematosus (SLE) has improved over the past decade, thanks to improved treatment of the disease, which now results in fewer fatal complications. This improvement has allowed physicians to focus their attention on the prevention of organ damage caused by this chronic, inflammatory disease, and by the medications used to control the disease. Osteoporosis is common in SLE patients; risk factors for osteoporosis include prolonged use of glucocorticoids, cyclophosphamide and possibly gonadotropin-releasing-hormone agonists. In premenopausal women with SLE, inflammation or SLE-related medications can increase bone turnover, which eventually weakens bone architecture, then reduces bone strength and increases the risk of fracture. Prevention and treatment of osteoporosis in SLE patients should entail a multifaceted approach. Levels of calcium, vitamin D and homocysteine should be evaluated, and age-appropriate supplementation instituted. The bone loss that results from systemic inflammation should be treated by reduction of the inflammation with glucocorticoids, potent anti-inflammatory agents or antiresorptive agents. The efficacy of this therapy can be monitored using bone mineral density scans. This Review briefly discusses the pathophysiology of the localized and generalized osteoporosis and osteonecrosis in SLE patients and recommends therapies to both prevent and treat these unfortunate complications of this disease.

Abstract
BACKGROUND Increased serum levels of homocysteine (Hcy) have been reported in patients with Behçet's disease (BD) with an established risk factor for vascular involvement. Recently, the authors demonstrated that elevated Hcy levels are associated with ocular involvement in such patients. On the other hand, elevated levels of Hcy can result from genetic errors. Indeed, a mutation in the 5,10-methylenetetrahydrofolate reductase (MTHFR C677T) gene influences Hcy metabolism and, therefore, MTHFR C677T polymorphism provokes hyperhomocysteinaemia. AIM To investigate the possible genetic factor for the elevation of plasma Hcy level in patients with BD by examining gene interaction with the MTHFR C677T polymorphism, a crucial factor of the Hcy metabolism. In addition, the authors aimed to evaluate if there is an association between the C677T polymorphism and the presence of ocular involvement in such patients. METHOD A total of 59 patients with BD (25 men, 34 women) with a mean age of 34.9 years and 42 age and sex matched healthy control subjects (19 men, 23 women; mean age 32.2) were included in this investigation. MTHFR gene polymorphism was investigated by the polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) of a genomic DNA fragment at nucleotide 677 in all subjects in both groups. The genetic equilibrium is assumed for the gene frequencies of the MTHFR polymorphism in both samples. RESULTS The genotype of the MTHFR gene differed between the Behçet's patients and control subjects (TT: 11.9 v 2.4%; CT: 55.9 v 61.9%; CC: 32.2 v 35.7 %). TT homozygous genotype was more frequently in BD patients than the controls, though the difference was not significant (p = 0.063). In BD patients with ocular involvement, however, the frequencies of MTHFR TT homogenetic type (27.8%) were significantly and statistically higher than those in BD patients without ocular involvement (4.9%, p = 0.022, odds ratio = 7.5), or the controls (2.4%, p = 0.003, odds ratio = 20.0). TT homozygous genotype was associated with an increased risk for ocular involvement. CONCLUSION Elevated serum levels of Hcy seem to be a result of C677T polymorphism of the MTHFR gene, with increased TT individuals over CC and CT genotype BD patients. Although no association was shown between the MTHFR reductase C677T polymorphism and the increased risk of oral aphtahe or genital ulcers, a mutation in this gene was associated with an increased risk of ocular involvement, suggesting genetic instability with a potential initiation of Hcy lowering therapy in this patient group.
