[Rheumatoid arthritis in elderly people].

Rheumatoid arthritis (RA) is a chronic, systemic connective tissue disease, characterized by progressive, destructive polyarthritis with internal organs involvement due to active, systemic inflammation. The onset of disease occurs usually in 4th or 5th decade of life. Since the general population is ageing, beginning of RA in older age is more and more common. The term elderly onset of rheumatoid arthritis (EORA) describes the disease with onset at age over 60. Several observational studies indicated, that proportion of women and men is comparable in EORA. Clinical course of the disease is characterized by sudden onset with general constitutional symptoms, high disease activity and inflammatory parameters. Involvement of large joints is more common, specially shoulder joints. Antibodies typical for RA (rheumatoid factor, anti-citrullinated peptide) are usually negative. More advanced destructive changes of joints and functional impairment are also characteristic for EORA patients in comparison with younger onset of RA (YORA). In clinical practice the use of methotrexate and biological drugs is less common, and glucocorticosteroids more common in EORA. Due to high RA activity, patients with EORA should be treated in the same way as YORA, with careful monitoring due to higher risk of adverse events associated with treatment.

Prospective assessment of cardiovascular risk parameters in patients with rheumatoid arthritis.

BACKGROUND: The study presents a prospective follow-up assessment of cardiovascular (CV) risk parameters in patients with rheumatoid arthritis (RA) in comparison with control subjects. METHODS: The study group consisted of 41 RA patients. The following parameters were assessed at subsequent visits [initial (T0), follow-up after 6 years (T6)]: traditional CV risk factors, carotid intima media thickness (cIMT), QTc duration, serum concentration of amino-terminal pro-brain natriuretic peptide (NT-proBNP). A comparative cIMT assessment was performed on 23 healthy controls of comparable age. RESULTS: The mean (SD) cIMT value in RA patients was significantly higher at T6 than at T0 [0.87 (0.21) vs 0.76 (0.15) mm, p < 0.001], the increase in patients with atherosclerotic plaques was noted. Patients with plaques were significantly older, had higher inflammatory parameters. The mean cIMT was significantly higher in RA patients than in controls at both T6, T0 visits. Certain traditional CV risk factors exacerbated during follow up. Unfavorable metabolic parameters and significantly higher cIMT were found in male patients than in female patients at T6. During follow-up, no significant differences in NT-proBNP, QTc were found. There were no significant relationships between cIMT, NT-proBNP, QTc and parameters of disease activity at T6. CONCLUSIONS: During the 6-year course of established RA, significant exacerbation of atherosclerosis was found, revealed by higher cIMT. A careful monitoring should be applied to patients with atherosclerotic plaques and of male gender due to higher burden of CV risk. In long-standing disease, traditional CV risk factors seem to play a key role, beyond the inflammatory activity.

Cardiovascular system changes in rheumatoid arthritis patients with continued low disease activity.

Systemic inflammation and disease activity seem to contribute to excessive prevalence of cardiovascular (CV) diseases (CVDs) in patients with rheumatoid arthritis (RA). The objective of the study was to assess chosen CV parameters in RA patients who have continuous low disease activity. The study group consisted of 70 RA patients without known CVD and 33 healthy controls, of a comparable age. All RA patients had continued low disease activity (DAS28 ≤ 3.2) from 2 to 7 years. The groups were assessed for: blood pressure, serum amino-terminal pro-brain natriuretic peptide (NT-proBNP), carotid intima media thickness (cIMT), electrocardiography (ECG), ejection fraction (EJ) and diastolic dysfunction (E/A ratio) in echocardiography. In RA patients in comparison with controls, significantly greater values of cIMT [0.83 (0.21) vs 0.62 (0.1) mm, p < 0.001] were found, as well as higher incidence of atherosclerotic plaques [43 (61.4%) vs 10 (30.3%), p = 0.003], prolonged QTc interval [439.6 (23.7) vs 414.0 (27.9) ms, p < 0.001]. High or very high Systemic Coronary Risk Evaluation (SCORE) was found in 32.9% of patients with RA and increased serum NT-proBNP in 71.4%. The mean values of CV parameters (cIMT, E/A, NT-proBNP, SCORE) were associated with age, disease duration, rheumatoid factor (RF-IgM), erythrocyte sedimentation rate (ESR). The results of our study indicate, that RA with continued low disease activity is associated with atherosclerosis and heart dysfunction. Strong relationships were found between CV parameters and patients' age, disease duration. Deterioration of CV parameters was associated with higher DAS28, ESR, RF-IgM concentration and bone erosions.

[Rheumatoid arthritis as a connective tissue disease].

The available data indicate that seropositive rheumatoid arthritis (RA) develops as a result of systemic, autoimmune reaction directed against a range of "self" peptides/proteins that have undergone specific forms of post-translational modification. The development and progress of autoimmunity may be triggered by non-specific, local inflammatory processes outside the joints, for example in the oral or respiratory mucous membrane. The disease occurs in genetically susceptible individuals under the influence of environmental risk factors that promote autoimmunity and consequently the inflammatory process. Smoking is particularly linked with RA pathogenesis. Synovitis of multiple, symmetrical, peripheral joints is the most typical feature of RA which results in irreversible damage to joints structure and as a consequence in disability of patients. However, the inflammatory process in the course of RA has a systemic, constitutional nature. Therefore, extra-articular symptoms with internal organ involvement may occur additionally to synovitis, what is an unfavorable prognostic factor. Extra-articular manifestations of RA are associated with the high disease activity both inflammatory and immunological. They occur in patients with severe form of the disease and contribute to a significant lifespan reduction. This is usually associated with progressive atherosclerosis and cardiovascular complications. The systemic inhibition of an abnormal immune system activity is the mainstay of the effective RA treatment. The currently used disease modifying antirheumatic drugs affect the activity and function of different constituents of the immune system, including B and T lymphocytes and the main pro-inflammatory cytokines, and contribute to autoimmune and inflammatory processes.

[Early reumatoid arthritis].

Rheumatoid arthritis (RA) is a systemic, autoimmune disease characterized by synovitis and irreversible joint destruction. RA development is a multi-stage process conditioned by the presence of genetic and environmental risk factors on the basis of which systemic immunization develops. The best known genetic factor predisposing to RA development is the polymorphism of HLA-DRB1 region of the major histocompatibility complex. Among environmental factors, importance in the pathogenesis of RA is attributed to the development of inflammation of the respiratory tract and chronic periodontitis caused by Porphyromonas gingivalis. The presence of antibodies and biomarkers of inflammation is well established before the onset of clinical symptoms of arthritis. The most well-known serological markers of RA include rheumatoid factor (RF) and anti-citrullinated peptide/proteins antibodies (ACPA). The search for new biomarkers that will allow the diagnosis of arthritis in the early, pre-destructive phase of the disease is still underway. The compound of anti-carbamylated protein antibodies (anti-CarP), adipocytokines or vitamin D with development of RA is tested. Several clinical studies have shown that disease-modifying anti-rheumatic drug (DMARD) therapy introduced at an early stage, referred to as a "window of opportunity", is associated with long-term benefits in the form of long-term remission and even complete remission of the disease.

Overlap syndromes in systemic sclerosis.

INTRODUCTION: It is known, that course of the disease differs between overlap syndromes (OS) and systemic sclerosis (SSc) group. AIM: To compare the prevalence of OS in limited cutaneous systemic sclerosis (lcSSc) and diffuse cutaneous SSc (dcSSc) and to analyze the presence of different manifestations in the SSc and OS group. MATERIAL AND METHODS: The study included 126 European Caucasian SSc patients (99 females and 27 males) hospitalized consecutively in the Department of Rheumatology and Connective Tissue Diseases. Patients fulfilled the American College of Rheumatology (ACR) classification criteria of SSc (57 - dcSSc and 69 - lcSSc). The study groups were determined according to the subtype of SSc, coexistence of other connective tissue diseases (CTDs), and incidence of clinical and serological manifestations. RESULTS: In our SSc study group, 28/126 patients (22%) were affected by more than one CTD. The prevalence of OS was significantly higher in the lcSSc group - 33% (23/69) compared to the dcSSc group - 8% (5/57). We found that mortality and digital ulcers were significantly higher, whereas kidney involvement and arthritis were significantly lower in the SSc group compared to the OS group. The prevalence of anti-topoisomerase I (a-Scl-70) was significantly higher, and prevalence of anti-PM/Scl, anti-Ro-52 antibodies was significantly lower in the SSc group compared to the OS group. CONCLUSIONS: Overlap syndromes were more common in lcSSc than in dcSSc. The course of the disorder and internal organ involvement were different in OS compared to SSc patients.

[Clinical and ultrasound assessment of the disease activity in patients with rheumatoid arthritis].

INTRODUCTION: Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory disease, leading to irreversible joint destruction and deformities. The adequate assessment of the disease activity enables the correct choice of therapy and evaluation of the treatment efficacy. The aim of the study was to compare different methods of assessment of the disease activity, using clinical data and ultrasonography (US) of joints, in patients with RA, in daily clinical practice. MATERIAL AND METHODS: The study group consisted of 68 patients with RA. The clinical assessment of the disease activity was performed using the Disease Activity Score based on evaluation of 28 joints (DAS28). Ultrasonography (US) examination of joints was performed in 24 small joints, evaluating hypertrophy and vascularity of the synovium. Ability to perform daily activities was measured using the modified Health Assessment Questionnaire (M-HAQ) Results: There were statistically significant correlations between the grade of synovial vascularity of joints and parameters of clinical activity [tender joints count (TJC), swollen joints count (SJC), DAS28] and laboratory acute phase parameters (ESR, CRP). The grade of synovial hypertrophy was significantly associated with SJC and DAS28, and not with laboratory parameters. M-HAQ value was significantly associated only with TJC. CONCLUSIONS: In RA patients an assessment of the disease activity should be performed taking into consideration several parameters, clinical activity, laboratory parameters, US and quality of life assessment. US examination enables verification of synovial inflammatory activity, which is not always possible in clinical examination.

[Discontinuation of immunosuppressive and immunomodulatory drugs in connective tissue diseases]. / Odstawienie leków immunosupresyjnych i immunomodulujacych w ukladowych chorobach tkanki lacznej.

Remission in connective tissue diseases became a realistic goal of therapy nowadays. However, there is lack of recommendations on the management after achieving a remission. Chronic exposure to immunosuppressive or immunomodulatory drugs may be associated with adverse events, that is why temporal withdrawal or discontinuation of treatment is advisable. In patients with rheumatoid arthritis (RA) who achieve sustained remission lasting for 6-12 months, an attempt to withdraw biological disease modifying antirheumatic drugs (bDMARDs) may be considered. In most patients with established RA discontinuation of bDMARDs is accompanied by a disease flare, butthe risk of loss of good therapeutic response is lower in case of slowly tapering by expanding the interval between doses or reducing the dose of bDMARDs. Patients with early RA are more likely to have successful discontinuation of therapy. Discontinuation of conventional DMARDs (cDMARDs) is usually associated with a disease flare, that is why tapering of doses is advised rather than stopping cDMARDs. DMARDs free remission occurs relatively rare, more often in patients with seronegative RA and with early onset of modifying treatment. In lupus nephritis (LN) patients with persistent, long-term remission, progressive tapering of doses of immunosuppressive drugs and glucocorticoids is recommended, with treatment discontinuation as a goal. An attempt of treatment withdrawal may be taken in patients remaining in LN complete remission as a consequence of maintenance therapy for 3 years.The process of slow tapering of doses preceding discontinuation of drugs, may last several months. The therapy with antimalarial drugs may be helpful to maintain remission after the treatment discontinuation. There is few data on treatment discontinuation in patients with systemic lupus erythematosus (SLE) without kidney involvement. Immunosuppressive drugs withdrawal is usually performed in patients with stable serological and clinically asymptomatic disease lasting for ≥ 2 years, on maintenance antimalarial therapy. Discontinuation of immunomodulatory treatment seems unlikely in primary systemic vasculitis.

Serum amyloid A as a marker of persistent inflammation and an indicator of cardiovascular and renal involvement in patients with rheumatoid arthritis.

OBJECTIVES: Rheumatoid arthritis (RA) is a systemic, inflammatory disease. Serum amyloid A (SAA) is an acute-phase protein, involved in pathogenesis of atherosclerosis. The aim of the study was to assess serum concentration of SAA in RA patients, with reference to other inflammatory parameters and markers of extra-articular involvement. METHODS: The study population consisted of 140 RA patients, low/moderate disease activity (L/MDA) in 98 (70%) patients and high disease activity (HDA) in 42 (30%). Comprehensive clinical and laboratory assessment was performed with evaluation of electrocardiogram and carotid intima-media thickness. RESULTS: The mean SAA concentration [327.0 (263.4) mg/L] was increased highly above the normal value, even in patients with L/MDA. Simultaneously, SAA was significantly higher in patients with HDA versus L/MDA. The mean SAA concentration was significantly higher in patients treated with glucocorticoids, was inversely associated with QTc duration, and was markedly higher in patients with atherosclerotic plaques, emphasizing increased CV risk. SAA was significantly higher in patients with increased cystatin-C level. CONCLUSIONS: In RA patients, high serum SAA concentration was strongly associated with activity of the disease and risk of CV and renal involvement. Recurrent assessment of SAA may facilitate searching patients with persistent inflammation and risk of extra-articular complications.

The Usefulness of Cellular Immune Inflammation Markers and Ultrasound Evaluation in the Assessment of Disease Activity in Patients with Spondyloarthritis.

BACKGROUND: The systemic inflammation response index (SIRI) and systemic immune-inflammation index (SII) have been introduced as inflammatory markers and predictors of poor prognosis in cancer and cardiovascular diseases. An appropriate evaluation of disease activity in spondyloarthritis (SpA) might be challenging. The purpose of this study was to evaluate the usefulness of cellular immune inflammation markers and ultrasound (US) evaluation of entheses and joints in the assessment of disease activity in SpA patients. METHODS: This cross-sectional study involved patients with SpA (62 axial SpA, 38 peripheral SpA, pSpA). The clinical data of both tender, swollen joint counts, erythrocyte sedimentation rate, C-reactive protein, white blood cell counts, and disease activity using Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Disease Activity Index for Psoriatic Arthritis (DAPSA), were recorded. The SIRI, SII, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) were calculated. US examination was performed (22 small joints, Achilles tendon, and plantar aponeurosis for enthesitis). RESULTS: The SII, SIRI, NLR, and PLR were higher, and LMR was lower in patients with high disease activity (BASDAI > 4). Higher SII was observed in pSpA patients with moderate/high disease activity (DAPSA > 14). The SIRI was correlated with clinical and laboratory parameters of disease activity. The SII was correlated with US parameters in pSpA. Higher SII and NLR values were found in patients with signs of activity compared with no activity in the US of peripheral joints. There were no associations with US changes in entheses. CONCLUSIONS: The results of this study point to the value of SIRI and SII as biomarkers of disease activity in patients with SpA. The SII was associated with synovitis in the US of the peripheral joints.

Metabolic Syndrome and Rheumatoid Arthritis Activity: An Analysis of Clinical, Laboratory, and Ultrasound Parameters.

(1) Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease associated with an increased incidence of metabolic syndrome (MetS). The aim of this study was to determine if there is an association between MetS and parameters of RA activity, as well as between metabolic parameters and indices of RA activity. (2) Methods: This study involved 65 patients with RA. MetS was diagnosed according to the 2009 IDF/AHA/NHLBI criteria. The comparative analysis was conducted between RA patients with MetS (RA (MetS (+)) and without MetS (RA (MetS (-)). The activity of RA was assessed using clinical, laboratory, and ultrasound (US) parameters. (3) Results: Compared with RA MetS (-) patients, RA MetS (+) patients were characterized by higher disease activity, according to Disease Activity Score (DAS28), Simplified Disease Activity Index (SDAI), and Clinical Disease Activity Index (CDAI). RA MetS (+) patients had significantly higher tender and swollen joint counts, and values of erythrocyte sedimentation rate, C-reactive protein, and US parameters (grey-scale (GSUS), power Doppler (PDUS)). Significant correlations were found between metabolic parameters (waist circumference, cholesterol and glucose concentrations) and indices of RA activity. (4) Conclusion: The results of this study show that, in patients with RA, the presence of MetS is associated with higher disease activity, based on several clinical, laboratory, and US parameters.

Adiponectin and Leptin as Biomarkers of Disease Activity and Metabolic Disorders in Rheumatoid Arthritis Patients.

Background: Rheumatoid arthritis (RA) is an autoimmune disease, characterized by inflammation of multiple joints, resulting in irreversible cartilage and bone destruction. Chronic disease activity may be associated with metabolic disorders and premature atherosclerosis. Adipokines are involved not only in metabolism regulation, but also in inflammatory and immune response. Aim: This study is designed to explore relationships between adipokines (adiponectin, leptin) and metabolic parameters, as well as disease activity, in patients with chronic RA. Methods: This cross-sectional study enrolled 109 patients with RA. The clinical assessment was performed including tender and swollen joint counts, Disease Activity Score 28 (DAS28), body mass index (BMI). The following laboratory parameters were performed: erythrocyte sedimentation rate, C-reactive protein, glucose, lipid profile, creatinine. Serum levels of adiponectin and leptin were assessed by enzyme-linked immunosorbent assay (ELISA). Results: The mean adiponectin and leptin serum concentrations remained within normal ranges. Both, adiponectin and leptin levels were not associated with current disease activity markers (clinical and laboratory), and type of treatment. Significant relationships were found between adipokines and metabolic parameters, as well as with coexistent conditions and RA characteristics. Higher leptin levels were noticed in patients with hypertension. In the multiple linear regression analysis, correlations were confirmed. Adiponectin was positively correlated with HDL-C (b = 0.37, p < 0.001), age (b = 0.39, p< 0.001), and negatively with glucose (b = -0.17, p = 0.03). Leptin was positively correlated with BMI (b = 0.58, p < 0.001), and negatively with estimated glomerular filtration rate (eGFR) (b = -0.30, p < 0.001). Conclusion: The results of this study show the value of adipokines as indicators of metabolic disorders, rather than inflammatory markers in patients with chronic RA, treated with immunosuppressive or biological drugs. High leptin level may indicate poor prognostic factors, kidney and cardiovascular complications. Adiponectin seems to be protective against metabolic disorders in chronic RA.

The relationship between carotid intima-media thickness and the activity of rheumatoid arthritis.

BACKGROUND: Cardiovascular (CV) disease, the most common cause of mortality in patients with rheumatoid arthritis (RA), is largely attributable to accelerated atherosclerosis. Carotid intima-media thickness (cIMT) has been approved as a surrogate marker of early atherosclerosis. OBJECTIVES: The aim of the study was to assess cIMT in RA patients lacking concomitant comorbidities potentially influencing cIMT value. METHODS: The study group consisted of 74 RA patients, without diagnosed heart or kidney disease, hypertension, diabetes, obesity, or current smoking (mean age, 46.4 [SD, 10.6] years; range, 19-70 years). Assessment of cIMT was determined by high-resolution B-mode ultrasonography in RA patients and 31 control subjects (mean age, 42.6 [SD, 8.0] years; range, 27-59 years). RESULTS: The mean maximum cIMT value was significantly greater in RA patients than in control subjects (0.73 [SD, 0.14] vs 0.59 [SD, 0.12] mm; P < 0.0001). In RA patients, cIMT correlated positively with a number of immunological and inflammatory parameters and also with amino-terminal pro-brain natriuretic peptide (NT-proBNP), age, metabolic variables (serum cholesterol, creatinine, cystatin C). In multiple linear regression analysis, significant association was found between cIMT and NT-proBNP and age. Patients without atherosclerosis (cIMT <0.6 mm) were younger and had significantly lower concentrations of NT-proBNP and total cholesterol, as well as higher estimated glomerular filtration rate. The course of RA in patients without atherosclerosis was characterized by shorter disease duration, lower tender joint count, and C-reactive protein. CONCLUSIONS: Values of cIMT were significantly greater in RA compared with control subjects. Features of RA, such as extra-articular manifestations, erosions, high inflammatory parameters, and long disease duration, even in the absence of traditional clinical CV risk factors, were associated with greater cIMT, suggesting an unfavorable CV risk profile.

The Relationship between Platelet Indices and Ultrasound, Clinical, Laboratory Parameters of Disease Activity in Patients with Rheumatoid Arthritis.

(1) Background: A proper assessment of disease activity is crucial for the management of a patient with rheumatoid arthritis (RA). Platelets seem to be involved in joint inflammation pathophysiology. Platelet indices (PIs) are markers of platelet activation, and include platelet count (PC), mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT). The purpose of the study was to assess the relationship between PIs and disease activity markers, both systemic (clinical, laboratory) and local (ultrasound, US), in patients with RA; (2) Methods: The study group consisted of 131 consecutive RA patients. The following assessments were performed: joint counts, Disease Activity Score (DAS28), complete blood cell counts, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and US of 24 small joints; (3) Results: Mean values of PIs remained within the normal reference ranges. Values of PC, PCT, PDW were significantly associated with disease activity markers, both clinical (DAS28, joint counts) and laboratory (CRP, ESR). In patients with high disease activity, PC, PCT were significantly higher and PDW lower. PC was positively correlated with Power Doppler US (PDUS) score. In patients with features of RA severity (antibodies positivity, extra-articular manifestations) PC and PCT were positively associated with all US parameters (Grey Scale US, PDUS, Global scores); (4) Conclusions: In patients with RA, PC and PCT may serve as positive disease activity markers and PDW may serve as a negative marker. PIs may be used as reliable, inexpensive markers of RA systemic activity; they may also serve as markers of local inflammation in the joints affected by RA.

Systemic Inflammatory Parameters in Patients with Elderly-Onset Rheumatoid Arthritis (EORA) and Young-Onset Rheumatoid Arthritis (YORA)-An Observational Study.

BACKGROUND: Rheumatoid arthritis (RA) occurs more often in elderly individuals. Elderly onset RA (EORA) (onset > 60 years) encompasses a specific subset of patients if compared with young onset RA (YORA) (onset at a younger age). There is a need to define reliable, simple markers to properly assess the inflammatory activity of RA. Hematological markers of systemic inflammation (Platelet-To-Lymphocyte (PLR) and Neutrophil-To-Lymphocyte (NLR) ratios) are novel measures of the inflammatory response. The goal of the study was to analyze the course of EORA vs. YORA patients and to assess associations between systemic and clinical disease activity markers, including PLR and NLR, in different subsets of patients. PLR and NLR have not previously been assessed in EORA and YORA. METHODS: The study group consisted of 113 consecutive patients (63 EORA and 50 YORA). The following assessments were performed: joint counts, Disease Activity Score (DAS28), complete blood cell counts, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). RESULTS: EORA was characterized by significantly higher disease activity markers (conventional inflammatory and clinical), a lower rate of remission or low disease activity, and less frequent use of biological drugs and glucocorticoids. The NLR and PLR were positively correlated with disease activity markers. The PLR was significantly lower in EORA compared with in YORA. CONCLUSION: EORA and YORA patients differed significantly. In EORA, conventional disease activity markers were higher, the PLR was significantly lower.

Adiponectin and leptin serum concentrations in patients with rheumatoid arthritis.

Adipose tissue is regarded as an active metabolic and endocrine organ producing adipokines. The purpose of the study was to evaluate adiponectin and leptin concentrations in rheumatoid arthritis (RA) patients (pts) in relation to disease duration and activity. The study group consisted of 80 RA pts. Serum adiponectin and leptin concentrations remained within normal ranges. Adiponectin concentration correlated positively both with the age and disease duration. Both adipokines levels correlated negatively with glomerular filtration rate. There were significant positive correlations between adipokines' concentrations and lipid profile components (between adiponectin and HDL-cholesterol, leptin and total cholesterol and LDL-cholesterol). In pts with long-standing RA, there was a negative correlation between adiponectin and numbers of tender, swollen joints and a positive relationship between leptin level and DAS28. The results confirm adipokines' involvement in the process of inflammation and atherosclerosis: protective and antiinflammatory adiponectin effect and proatherogenic and proinflammatory leptin function.

The Relationship between Hematological Markers of Systemic Inflammation (Neutrophil-To-Lymphocyte, Platelet-To-Lymphocyte, Lymphocyte-To-Monocyte Ratios) and Ultrasound Disease Activity Parameters in Patients with Rheumatoid Arthritis.

BACKGROUND: An accurate measurement of disease activity is essential for the appropriate management of a patient with rheumatoid arthritis (RA). Hematological markers of systemic inflammation (Neutrophil-to-Lymphocyte (NLR), Platelet-to-Lymphocyte (PLR) and Lymphocyte-to-Monocyte (LMR) ratios) are reported to be novel, sensitive measures of inflammatory response, in addition to conventional markers (erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Disease Activity Score (DAS28)). The goal of the study was to assess the relationship of NLR, PLR, and LMR with ultrasonography (US) parameters of disease activity in RA patients. METHODS: The study group consisted of 126 consecutive RA patients (100 women, 26 men). The following assessments were performed: joint counts, DAS28, complete blood cell counts, ESR, CRP, and US of 24 small joints. RESULTS: NLR and PLR were significantly positively correlated with all US parameters of disease activity (Grey Scale US, Power Doppler US, and Global scores). The mean values of NLR and PLR were significantly higher in patients with poor prognostic factors: moderate/high vs. low disease activity (NLR: p < 0.001; PLR: p = 0.007), anti-CCP positive vs. anti-CCP negative (NLR: p = 0.01; PLR: p = 0.006). In multiple regression tests, significant correlations were confirmed for: NLR and DAS28 (p = 0.04), and CRP (p = 0.001); PLR and Power Doppler US (p = 0.04), and ESR (p = 0.02). No correlation was found for LMR. CONCLUSION: NLR and PLR are associated with US disease activity parameters and may serve as reliable, inexpensive markers, with prognostic significance in RA.

Diastolic dysfunction in rheumatoid arthritis patients with low disease activity.

INTRODUCTION/OBJECTIVES: Patients with rheumatoid arthritis (RA) are at increased risk for congestive heart failure (CHF) and left ventricular diastolic dysfunction (LVDD), as compared to the general population. High disease activity is to be associated with higher incidence of cardiovascular disease (CVD), CHF, and mortality in RA patients. LVDD is not anticipated in RA patients without CVD symptoms and may be underdiagnosed especially in those with low disease activity. METHOD: The study group consisted of 70 RA patients (54 women, 16 men) with no CVD and 33 healthy controls, of comparable age. All RA patients had low disease activity (DAS28 ≤ 3.2) from 2 to 7 years. Laboratory and imaging assessments included metabolic, RA-related, and cardiovascular parameters. Echocardiographic and Doppler studies were conducted in patients and controls with assessment of ejection fraction (EF) and diastolic dysfunction (assessed as E/A ratio). RESULTS: The mean E/A ratio did not differ significantly between RA patients and healthy controls (1.08 (0.28) vs 0.99 (0.21), NS); comparable numbers of patients and controls had abnormal E/A (< 1.0) (26 (37.1%) vs 10 (30.3%), NS). Patients with decreased E/A were significantly older and had higher disease duration, activity, and presence of bone erosions than their RA counterparts with normal E/A. The mean EF was not significantly different in patients and controls. CONCLUSIONS: The prevalence of DD as expressed by E/A ratio in RA patients with continued low disease activity was not different from that of controls. Higher disease duration and severity may predispose to DD occurrence in patients with preserved EF.

Gender Differences in Cardiovascular Risk Profile in Rheumatoid Arthritis Patients with Low Disease Activity.

OBJECTIVE: Patients with rheumatoid arthritis (RA) have an excess risk of cardiovascular (CV) disease (CVD). The objective of the study was to compare CV risk profile in female and male RA patients with low disease activity. MATERIALS AND METHODS: The study group consisted of 70 RA patients with continuous low disease activity and no CVD (54 women, 16 men) and 33 healthy controls of comparable age. The groups were assessed for blood pressure, serum amino-terminal pro-brain natriuretic peptide (NT-proBNP), carotid intima media thickness (cIMT), electrocardiography, ejection fraction (EF), and diastolic dysfunction (DD). RESULTS: Significantly higher burden of atherosclerosis, as revealed by higher cIMT, was found in males [0.93 (0.2) mm] vs females [0.80 (0.2) mm]. The risk of 10-year CVD was significantly higher in men than in women with RA. High/very high risk of fatal CVD was found in 62.5% of male patients. Males were significantly more often current/ex-smokers and had lower HDL-cholesterol and higher atherogenic index. There were no significant differences in NT-proBNP, QTc duration, and parameters of EF and DD. CONCLUSIONS: In RA patients with continued low disease activity, a higher burden of atherosclerosis was found in males than in females. The data suggest a significant impact of traditional CV risk factors.
