Myasthenia Gravis Triggered by a COVID-19 Infection: A Case Report and Literature Review.

Myasthenia gravis (MG) is an autoimmune disease that induces skeletal muscle weakness, affecting different muscle groups. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause of coronavirus disease 2019 (COVID-19), became both a diagnostic and a therapeutic challenge during the pandemic. The effects of COVID-19 are not only limited to the acute symptoms but also to the post-infectious sequelae. We present the case of a 30-year-old Caucasian woman, with no significant medical history, who presented to the emergency room with acute respiratory failure. The patient tested positive for SARS-CoV-2 with a rapid antigen test and during hospitalization developed a myasthenic crisis, ultimately being diagnosed with seropositive MG.

Depression in Rheumatoid Arthritis: Prevalence and Effects on Disease Activity.

Background:The primary objective of this study was to estimate depression's prevalence in a cohort of rheumatoid arthritis (RA) patients, and the secondary objective was to evaluate the impact of depression on disease activity over time. Methods: We included all patients with RA presenting to our clinic from 2019 to 2020, who had three follow-up visits available. Depression prevalence was calculated using the patient's history of diagnosed depression, and disease activity was assessed using the disease activity score for 28 joints (DAS28) and its components: tender joint count (TJC), swollen joint count (SJC), pain value on a visual analog scale (VAS), and inflammatory markers. Results: A total of 400 RA patients were included, 75 of whom had diagnosed depression, generating a prevalence of 18.8%. The mean values of DAS28 and its components were higher, with statistical significance, in the depression subgroup at all three follow-ups (p < 0.001). Conclusions: Depression is prevalent in the RA population, and leads to higher disease activity in dynamic evaluations. Assessing depression could be a psychological marker for RA prognosis with an important outcome in controlling disease activity.

Anterior Intercondylar Notch Geometry in Relation to the Native Anterior Cruciate Ligament Size.

BACKGROUND: The intercondylar notch (ICN) and the anterior cruciate ligament (ACL) are important structures in knee morphometry, with key roles in stabilizing the knee. AIM: To determine the associations between the specific shape of the ICN (A-, W-, or U-shape) and the ACL size in patients with intact ACLs. METHODS: Magnetic resonance imaging (MRI) scans were independently analyzed by two experts: one orthopedic surgeon and one imaging physician. In all cases, the following measurements were taken based on the existing definitions: ACL area, anterior ICN (aICN) area, ICN width, lateral trochlear inclination (LTI), and Insall-Salvati index. RESULTS: A total of 65 cases (50.8% male; 33.8 ± 10.2 years mean age at inclusion) were included in the study. The ACL and aICN areas were significantly larger in patients with U-shaped compared with A-shaped and W-shaped ICNs: 0.50 (0.20-0.80) vs. 0.40 (0.20-0.80) vs. 0.40 (0.30-0.80), p = 0.011 and 1.16 (0.57-3.60) vs. 0.47 (0.15-0.95) vs. 0.37 (0.15-0.81), p < 0.001, respectively. Internal meniscal lesions were more common in cases with U-shaped ICNs (64.0%), while external ones were more common in W-shaped ICN cases (35.3%). None of the A-shaped cases had external chondral or meniscal lesions. The ACL area was significantly larger in males and internal meniscal injuries, with no differences between chondral lesions, external meniscal injuries, patellar chondral lesions, patella alta, or trochlear dysplasia. CONCLUSION: The specific shape of the intercondylar notch was associated with the anterior cruciate ligament-anterior intercondylar notch (ACL-aICN) area size correlation, with a strong correlation between ACL and aICN area when the intercondylar notch was A-shaped or W-shaped, and a low correlation when the notch was U- shaped. The specific shape of the intercondylar notch (A-, W-, or U-shape) was associated with the occurrence of both internal and external meniscal injuries, with the U-shaped intercondylar notch morphometry being more frequent in cases with internal meniscal injuries and the W-shape being more common in cases with external meniscal injuries.

Nail Ultrasound in Psoriasis and Psoriatic Arthritis-A Narrative Review.

Ultrasonography has advantages for assessing psoriatic arthritis (PsA) due to its ability to evaluate several targets, including joints, entheses, and tendons, but also skin and nails. Although ultrasound is widely used in PsA, nail ultrasound, despite its potential as a non-invasive method for the early detection of inflammation in the nail apparatus, has low applicability in medical practice, as probes with a higher frequency are needed compared with the frequency of probes usually used. In the present article, we have narratively evaluated the studies published in the last 5 years (19 February 2018-18 February 2023) on nail ultrasound value in the diagnosis and monitoring of PsA. The studies published during this period share common measurement parameters, such as the OMERACT definition of enthesis published in 2018. We included original articles published in PubMed and Web of Science using the following search terms in all possible combinations: psoriatic arthritis, psoriasis, ultrasound, and nail. Articles were declared relevant if they presented data on nail morphology, power Doppler evaluation and nearby structure evaluation, while focusing on digitorum extensor enthesitis. In most of the studies, common morphological parameters were generally increased in patients with psoriasis or PsA and were demonstrated to change with medication. The thickness of the extensor tendon was greater in patients with PsA and psoriasis versus controls and it was correlated with nail clinical changes, especially the presence of onycholysis. The presence of PD showed large variability in healthy individuals. The link between enthesitis and nail involvement is still a subject of controversy, taking into account the latest histological findings. The use of ultrasound in the evaluation of nail and DIP enthesitis remains a challenge and an area of research in the coming years.

Comparison of Efficacy and Safety of Original and Biosimilar Adalimumab in Active Rheumatoid Arthritis in a Real-World National Cohort.

Background and Objectives: Real-world evidence should reflect the evidence obtained from controlled trials; therefore, the study aimed to compare biosimilar adalimumab (bADA) to original adalimumab (oADA) in terms of efficacy and safety in a real-life national cohort of rheumatoid arthritis (RA) patients. Materials and Methods: The following study is a prospective observational study in which we analyzed patients treated with reimbursed biologics from the Romanian Registry of Rheumatic Diseases (RRBR). RA cases must fulfill the 2010 classification criteria, as well as specific inclusion and exclusion criteria. The RRBR database was queried for all RA patients starting oADA or bADA (FKB327, GP2017, MSB11022, SB5 available) from 2 May 2019 (the first bADA initiation) until 26 March 2022 (study search date). Results: The study included 441 patients who started oADA (48.3%) or bADA (51.7%) in the same time period. At baseline, patients starting bADA had a significantly higher mean age and lower prevalence of women. After the first six months of treatment, there were no significant differences between the oADA and bADA regarding rates of Boolean (15.0% vs. 12.3%, p = 0.401), DAS28-CRP (32.4% vs. 34.2%, p = 0.686) and SDAI (16.4% vs. 14.0%, p = 0.483) remission rates. There were 107 cases of adverse events (AE): 81.3% on oADA and 18.7% on bADA. Notably, 51.4% of AE were infections. Regarding severity, 49.5% of AEs were mild, 34.6% were moderate, and 15.9% were severe. Conclusion: Biosimilar adalimumab showed similar efficacy and safety to original adalimumab after the first six months of treatment in RA patients from a national registry.

Uncommon onset manifestations without renal involvement in microscopic polyangiitis: A case report.

Microscopic polyangiitis (MPA) is a rare, idiopathic, autoimmune, systemic disease that most frequently involves the kidneys. The present study reports the case of a 48-year-old female patient who presented with diffuse myalgia, arthralgia of both hands and feet for 2 weeks before being admitted to the hospital. The patient exhibited involuntary loss of weight and occasional slight fever. Physical examination noted microstomia and perioral radial furrows, slight skin induration of the hands, discrete cyanotic skin areas on the dorsal side of both feet. The patient also presented bilateral crepitant rales. Laboratory findings at admission revealed non-specific biological inflammatory syndrome consisting of high erythrocyte sedimentation rate and high C-reactive protein. The patient was initially suspected of systemic sclerosis due to the appearance of microstomia and the slight skin induration of the hands with diffuse arthralgia and myalgia, although with negative immune tests (anti-SCL70 and anti-centromere B antibodies) and normal nailfold capillaroscopy. Instead, a high titer of MPO-ANCA was detected. The computerized tomography scan revealed early diffuse interstitial lung disease (ILD). Cases of MPA with pulmonary involvement, such as ILD before the onset of vasculitis or kidney involvement, are known. Therefore, the diagnosis of MPA was formulated considering the symptoms, the clinical examination and the high titer of MPO-ANCA. The particularity of the present case consists in the uncommon onset with atypical skin changes, positivity to MPO-ANCA, absent renal dysfunction and ILD involvement.

Depression in Rheumatoid Arthritis: A Narrative Review-Diagnostic Challenges, Pathogenic Mechanisms and Effects.

Depression is one of the most frequent comorbidities in rheumatoid arthritis (RA); it takes an important toll on the quality of life of these patients and also leads to a decrease in life expectancy. The current article is a narrative review on depression in RA, with the objective to emphasize and raise awareness on the high prevalence, pathogenic mechanisms, and effects that depression has on RA patients. In RA, the prevalence of depression has been shown to be 2 to 3 times higher than in the general population, with a meta-analysis reporting that 16.8% of RA patients have a major depressive disorder. Future studies are needed to determine the most accurate self-reported depression questionnaires and their ideal threshold for defining depression as compared to diagnostic interview as gold-standard for patients with RA to allow better comparisons across studies. The pathogenesis of depression remains to be fully understood, but recent specialty literature suggests that immune-mediated processes are involved and that there are similarities between the neural networks recruited in inflammation and those implicated in the pathophysiology of depression. Depression in patients with RA is associated with poor long-term outcomes. Multiple studies have shown that depression in RA is associated with increased pain, fatigue, and physical disability. It alters treatment compliance, causes more comorbidities, and leads to higher mortality, partly through increased suicide risk. Depression in RA also increases health service utilization and healthcare costs directly through hospitalization, but also indirectly through loss of work productivity. Assessing depression could be a significant psychomarker of rheumatological outcome in RA.

Ultrasound Enthesitis in Psoriasis Patients with or without Psoriatic Arthritis, a Cross-Sectional Analysis.

Background and objectives: The main objective of the current study was to describe the prevalence of enthesitis at different sites in a group of patients with psoriasis with or without psoriatic arthritis (PsA). Materials and Methods: The study included adult patients with psoriasis who underwent clinical examination, laboratory tests and ultrasound examination of the entheses. The enthesitis ultrasound scores (BUSES, MASEI, GUESS) were evaluated; the presence of OMERACT-defined enthesitis was also recorded for each scan site. Results: The study included 16 (57.1%) patients with PsA and 12 (42.9%) patients with psoriasis, with an increased average body mass index (29.3 kg/m2). Compared to psoriasis patients, PsA patients had a higher prevalence of nail psoriasis (68.8% compared to 33.3%; p = 0.063). There were no significant differences regarding the clinical examination of entheses between patients with psoriasis and patients with PsA (p = 0.459). Ultrasound scores, BUSES, GUESS and MASEI proved to have statistically significant higher median values in PsA patients compared to psoriasis patients. Compared to psoriasis patients, PsA patients had a significantly higher prevalence of OMERACT-defined enthesitis of the quadriceps tendon and inferior patellar ligament (both 81.3% compared to 25.0%, p = 0.003). Clinical examination of the lateral epicondyle and of the superior patellar ligament was consistent with their ultrasound examination (κ = 0.357, p = 0.043, respectively, κ = 0.404, p = 0.008). Conclusions: Clinical enthesitis scores do not differ between psoriasis and PsA patients. All analyzed ultrasound scores are significantly higher in patients with PsA. OMERACT-defined enthesitis has the ability to discriminate sonographic enthesitis between the two subgroups for bilateral quadriceps and inferior patellar tendon enthesitis. Bilateral ultrasound damage of entheses can suggest a PsA diagnosis.

Lung Damage in Rheumatoid Arthritis-A Retrospective Study.

The current study aimed to evaluate rheumatoid arthritis (RA) patients with interstitial lung disease (ILD) in clinical practice and whether disease characteristics are associated with X-ray and high-resolution computed tomography (HR-CT) findings. Medical history of RA patients from a tertiary rheumatology clinic was retrieved from its electronic database starting from 1 January 2019 until the study date (8 August 2022) using International Classification of Disease version 10 codes for RA, ILD and exclusion criteria. The study included 78 RA patients (75.6% women, 15.4% active smokers), with average time from RA to ILD of 5.6 years. Regarding chest X-ray findings, men had a higher prevalence of nodules, combined fibrosis and nodules and combined bronchiectasis and nodules, rheumatoid factor (RF)-positive patients had a higher prevalence of fibrosis and anti-cyclic citrullinated peptide antibodies (ACPA)-positive patients had a higher prevalence of bronchiectasis. Regarding HR-CT findings, patients actively treated with methotrexate had a higher prevalence of nodules; a combination of fibrosis and nodules; combination of emphysema and nodules; and combination of fibrosis, emphysema and nodules. ILD develops within approximately 5 years from RA diagnosis, and ILD-associated imaging findings on chest X-rays and HR-CT are more prevalent among men with RA, among patients with positive RA serology (RF and/or ACPA) and RA patients on methotrexate.

Efficacy and safety of original and biosimilar etanercept (SB4) in active rheumatoid arthritis - A comparison in a real-world national cohort.

OBJECTIVE: The study aims to compare the efficacy and safety of biosimilar etanercept (SB4) to original etanercept (ETN) in a real-life national cohort of rheumatoid arthritis (RA). METHODS: Data from RA patients were retrieved electronically from the Romanian Registry of Rheumatic Diseases (RRBR), which contains all patients receiving biologics in the country. RESULTS: The study included 242 patients with efficacy and safety data after 6 months of treatment: 123 (50.8%) with ETN, 119 (49.2%) with SB4. There were no significant differences after 6 months regarding composite scores of RA activity between patients on ETN and SB4 (e.g. DAS28 remission: 18.7% in ETN group and 17.6% in SB4 group, p = 0.823; Boolean remission: 11.4% in ETN group and 11.8% in SB4 group, p = 0.926). There were 11 adverse events (AE) in the ETN subgroup (including 3 severe AE: lower respiratory tract infection, enterocolitis and anaphylaxis) and 12 AE in SB4 subgroup (including 4 severe AE: lower respiratory tract infection, vasculitis, anaphylaxis and rash). CONCLUSION: Biosimilar and original etanercept showed similar efficacy and safety after the first 6 months of treatment in RA patients from a national registry, which brings further evidence for biosimilarity in unselected patients in real-world setting.

Ankle involvement in rheumatoid arthritis - a comparison of inflammatory signs on musculoskeletal ultrasound and magnetic resonance imaging.

AIM: To evaluate the frequency of tibiotalar and subtalar joints together with extensor, flexor and peroneal tendons inflammatory lesions in rheumatoid arthritis (RA) patients by using ultrasound (US) and magnetic resonance imaging (MRI). MATERIAL AND METHODS: Fifty RA patients and 25 healthy subjects were prospectively included. All patients and controlsunderwent clinical examination (to screen for swollen and/or tender ankles) and ankle US and MRI (to screen for synovialhypertrophy - SH, tenosynovitis and power Doppler - PD signals). The imaging tests were compared using overall agreement, positive agreement, Cohen's κ, sensitivity, specificity and positive likelihood ratio. RESULTS: The subtalar joint had the highest frequency of US-detected SH (30%), as well as positive PD signals (10%). Regarding US joint effusion, the tibiotalar joint recorded the highest frequency (44%). The most frequent US tenosynovitis was detected in the tibialis posterior tendon (40%). Compared to MRI, US evaluation of tibiotalar joints had very good agreement and large effect on detection probability for both SH and effusion (kappa 0.84, positive likelihood ratio 21.1). Compared to MRI, the sensitivity and specificity for US joint involvement ranged between 72.0-88.5% and 82.4-95.8%, and for tenosynovitis were 33.3-78.6% and 85.2-100%,  respectively. Compared to asymptomatic RA patients (n=25), those with at least one symptomatic ankle (n=25) had significantly higher frequencies of both SH and effusion in all the evaluated structures. CONCLUSION: US has high sensitivity and specificity in detecting RA inflammatory lesions in the ankle and rearfoot, in very good agreement with MRI. The high frequency of ankle inflammatory lesions in RA should result in increased interest in the imaging evaluation of these structures.

A novel quantitative method for estimating bone mineral density using B-mode ultrasound and radiofrequency signals-a pilot study on patients with rheumatoid arthritis.

The objective of the present study was to evaluate whether an innovative quantitative ultrasound (QUS) technique, Radiofrequency Echographic Multi Spectromety, which combines B-mode ultrasound and radiofrequency signals, is reliable in typical Romanian patients compared to previous results obtained using dual-energy X-ray absorptiometry (DXA). The study prospectively included previously unscreened post-menopausal females with rheumatoid arthritis (RA) and age-matched healthy controls. Bone mineral density (BMD) measurements were performed with an EchoS machine (Echolight®), which combines B-mode ultrasound and radiofrequency signals. The study included 106 RA patients, with a median disease duration of 3.2 (0.5-22) years and 119 controls. RA patients had a significantly lower body weight, body mass index (BMI) and basal metabolic rate (BMR) than the controls, while the prevalence of obesity and body fat differed insignificantly. RA patients had a significantly lower spine and hip BMD, higher fracture risk and higher prevalence of osteoporosis. Compared to RA patients without osteoporosis, those with osteoporosis were significantly older and had a longer menopause duration, but they had a significantly lower BMI, body fat, BMR and prevalence of obesity. Among the controls and RA patients, the median spine and hip BMD became significantly higher as the BMI increased from underweight to obesity. In conclusion, osteoporosis is prevalent among RA patients, as a part of a complex transformation of body mass composition, involving BMI and fat mass. The novel QUS scanning technique was able to replicate the results of the established DXA measurement of BMD and is potentially suitable for screening wide populations for osteoporosis.

Analysis of the Indirect Costs of Rheumatoid Arthritis in Romania.

Rheumatoid arthritis (RA) is associated with increased costs generated by resource utilization and loss of work productivity. We have studied 206 RA patients and analyzed indirect costs of RA in Romania (estimated using the human capital approach) in comparison with reported data for other countries. Data were collected using self-reported questionnaires. The average age at inclusion was 55 years, with mean disease duration of 9.4 years; 55 patients had permanent work disability due to RA; 6.35 days of sick leave per patient were reported for the entire year of follow-up; the cost of permanent work disability was 1256€ per patient. From a societal perspective, the average indirect costs for a patient with RA were 1506€, significantly lower than the ones reported by other countries, especially due to the low monetary value of paid work.

Usefulness of complex bacteriological and serological analysis in patients with spondyloarthritis.

Spondyloarthritis (SpA) is a group of associated chronic systemic inflammatory immune-mediated rheumatic diseases affecting axial and peripheral joints and entheses. The aim of the present study was to identify what parameters are useful to determine in order to better understand the correlation between the disease activity/severity and the microbiological results/immune status against intestinal and/or urogenital pathogens. Microorganisms known to trigger SpA, including Klebsiella spp., Yersinia spp., Salmonella spp., Campylobacter spp. and Chlamydia spp., were analyzed in various specimens (stool, urine, synovial fluid and serum) collected from 27 randomly selected SpA patients and 26 healthy controls using a combined direct and indirect approach relying on conventional culture technique and nucleic acid-based assays together with serological testing by ELISA. Although Escherichia coli derived from phylogroup A prevailed in the gut microflora of the patients and controls, differences were observed regarding the representatives of the other phylogroups with a higher prevalence of E.coli members of phylogenetic group B1 in the stool specimens of patients. Antibodies against the targeted species were detected in SpA patients and controls, and the serological profiles of the former were more diverse and complex. In conclusion, the detection of anti-bacterial antibodies combined with other specific laboratory investigations should be more extensively used to monitor SpA patients in association with their symptoms and in order to determine and administer more effective therapeutics.

A referable clinical pattern of spondyloarthritis-associated uveitis.

Objective. The aim of the study was to identify a clinical pattern of spondyloarthritis (SpA)-associated uveitis in order to facilitate proper rheumatologic referral by ophthalmologists. Methods. Demographic data were recorded and acute phase reactants were measured using standard methods between May and August 2017, for all adult patients (age > 18 years) presenting with acute uveitis (standardization of uveitis nomenclature). Afterwards, they were referred to a rheumatology clinic to be screened for the 2009 Assessment of SpondyloArthritis International Society (ASAS) classification criteria of SpA. SpA and non-SpA patients were then compared using appropriate statistical tests (significant if p < 0.05). All the patients offered a written informed consent and the study was approved by the local ethics committee. Results. The sample included 67 subjects, of whom 32 (47.8%) were classified with SpA, of whom 21 were known with this diagnosis (median disease duration of 13.6 years), while 11 (34.4% of the SpA subgroup) fulfilled the ASAS classification criteria for SpA without a prior diagnosis. Compared to non-SpA patients, SpA patients were more frequently male urban dwellers, they were significantly younger, they had a higher prevalence of HLA-B27 and recurrent uveitis, and they had higher median of C-reactive protein and lower median of white blood counts. Conclusions. Uveitis is an important revelatory manifestation of SpA. Young men presenting in an ophthalmology department with acute anterior uveitis and inflammatory back pain should be referred to a rheumatology unit. Abbreviations: AAU = Acute Anterior Uveitis, AS = Ankylosing Spondylitis, ASAS = Assessment Of Spondyloarthritis International Society, CRP = C-Reactive Protein, ESR = Erythrocyte Sedimentation Rate, HLA = Human Leukocyte Antigen, IBP = Inflammatory Back Pain, IBD = Inflammatory Bowel Disease, IL = Interleukin, MRI = Magnetic Resonance Imaging, Nsaids = Non-Steroidal Anti-Inflammatory Drugs, SD = Standard Deviation, Spa = Spondyloarthritis, Tnfα = Tumour Necrosis Factor Alpha, WBC = White Blood Count.

Area of Residence and Socioeconomic Factors Reduce Access to Biologics for Rheumatoid Arthritis Patients in Romania.

INTRODUCTION: The study aimed to evaluate the influence of socioeconomic factors on rheumatoid arthritis (RA) patients' access to biologics in Romania. METHOD: Cross-sectional data were collected in January 2014 from the Romanian Registry of Rheumatic Diseases (RRRD) comprising all RA patients on biologics from 42 Romanian counties. "Territorial" access to biologics was defined by patients receiving biologics in their home county. A county was "equitable" if <25% of RA patients received biologics outside it. RESULTS: The RRRD included 4507 RA patients aged 56.7 ± 12.1 years, with a disease duration of 12.1 ± 8.3 years. Urban dwellers (67.8%) had a significantly higher prevalence of territorial biologic access than rural dwellers (83.1% compared to 74.1%; p < 0.001). Gross domestic product (GDP) in 1000 €/capita/county (odds ratio (OR) = 1.224) and number of physicians/1000 inhabitants/county (OR = 2.198) predict territorial access to biologics and also predict the number of territorially treated RA patients. Inequitable counties exhibited significantly lower socioeconomic indicators than equitable counties. CONCLUSION: In Romania, RA patients' access to biologics varies significantly between counties. Urban dwellers and patients living in counties/regions with high living standards are more likely to receive biologics locally than those living in more deprived areas.

Dual X-Ray Absorptiometry Whole Body Composition of Bone Tissue in Rheumatoid Arthritis - a Cross-Sectional Study.

OBJECTIVES: Previous studies of bone tissue in rheumatoid arthritis (RA) using dual X-ray absorptiometry (DXA) concentrated on regions of interest that were used to diagnose osteoporosis. This study aimed to compare the whole body bone tissue (wbBT) of RA patients with healthy subjects and to identify the RA variables which significantly predict wbBT. METHODS: The study was cross-sectionally designed to include postmenopausal RA patients and age-matched healthy female controls. All 107 RA patients and all 104 controls underwent clinical examination, laboratory tests and whole body DXA composition, which recorded total and regional bone indices. Non-parametric standard statistical test and regression models after data normalization were used to assess correlations, associations and differences. RESULTS: Compared to controls, RA patients had significantly lower whole body and regional bone mass (14.9 kg compared to 15.5 kg; p = 0.031). Disease duration (r = -0.402 ; p < 0.001), C-reactive protein (r = -0.279; p = 0.015) and inflammation (2.5% wbBT compared to 2.9%; p = 0.043), radiographic damage (14.3 kg compared to 16.2 kg; p < 0.001), disease activity scores (r = -0.275 ; p = 0.018 for HAQ) are significantly correlated/associated with lower wbBT. Clinical structural damage is associated with lower wbBT and it can significantly predict them (R2 = 0.014; p = 0.001), while glucocorticoid treatment, even in low doses, was associated with lower wbBT percent (2.6% compared to 2.8%; p = 0.045). Treatment with biologics was associated with a lower rate of whole body osteoporosis (0% compared to 22.2%; p = 0.013). CONCLUSIONS: The main associated factors with the generalized bone loss in female RA patients are disease duration and disease activity. Clinical structural damage is the most powerful predictor of the whole body bone loss. These results suggest a general disturbance of skeletal bone metabolism in RA and could explain a greater risk of fragility fractures of non-central sites (e.g. ribs, tibia, ankles etc.) compared to post-menopause osteoporosis.

Whole body bone tissue and cardiovascular risk in rheumatoid arthritis.

Introduction. Atherosclerosis and osteoporosis share an age-independent bidirectional correlation. Rheumatoid arthritis (RA) represents a risk factor for both conditions. Objectives. The study aims to evaluate the connection between the estimated cardiovascular risk (CVR) and the loss of bone tissue in RA patients. Methods. The study has a prospective cross-sectional design and it includes female in-patients with RA or without autoimmune diseases; bone tissue was measured using whole body dual X-ray absorptiometry (wbDXA); CVR was estimated using SCORE charts and PROCAM applications. Results. There were 75 RA women and 66 normal women of similar age. The wbDXA bone indices correlate significantly, negatively, and age-independently with the estimated CVR. The whole body bone percent (wbBP) was a significant predictor of estimated CVR, explaining 26% of SCORE variation along with low density lipoprotein (P < 0.001) and 49.7% of PROCAM variation along with glycemia and menopause duration (P < 0.001). Although obese patients had less bone relative to body composition (wbBP), in terms of quantity their bone content was significantly higher than that of nonobese patients. Conclusions. Female patients with RA and female patients with cardiovascular morbidity have a lower whole body bone percent. Obese female individuals have higher whole body bone mass than nonobese patients.

Cardiovascular risk in psoriatic arthritis - a cross-sectional study.

OBJECTIVES: The present study aims to estimate long term cardiovascular risk in psoriatic arthritis (PsA) patients and to identify clinical and/or laboratory features which influence this risk. OUTCOMES: The PsA group included 44 males and 59 females (p = 0.167) with an average age of 52 years (23-80). SCORE was significantly correlated with age of onset, BMI, triglycerides, FPG. Among these patients, males, smokers, those with axial involvement, with IHT, with AHT and those not treated with glucocorticoids had a significantly higher SCORE. The subgroup of 56 PsA women, age-matched with 56 normal women, had a significantly higher SCORE, even after controlling for covariates. CONCLUSIONS: Cardiovascular risk of PsA patients estimated on SCORE charts correlates with metabolic clinical and laboratory features and is associated with classical cardiovascular risk factors. The axial involvement in PsA is associated with a higher cardiovascular risk when compared to non-axial PsA. Women with PsA have a higher cardiovascular risk than normal women, which sustains the opinion that PsA may be considered an independent cardiovascular risk factor.
