33633871 Macrophage Activation Syndrome Upon Initiation of Adalimumab in a Patient With Longstandin 2021 Jan 20 Macrophage activation syndrome (MAS) is a subset of hemophagocytic lymphohistiocytosis (HLH) described in patients with rheumatological disorders. Some triggers of MAS and HLH include infection, malignancy, rheumatological disease, HIV, and rarely medications such as immunosuppressants. In recent medical literature, biologic agents are increasingly recognized as a potential trigger, but the mechanism behind this remains poorly understood. We describe the case of a patient who developed MAS after initiating adalimumab and propose a potential pathophysiological link between biologics and this syndrome.
34925651 Imaging of cervical spine involvement in inflammatory arthropathies: a review. 2021 The cervical spine can be affected by many types of inflammatory arthropathies, and the most common autoimmune diseases with cervical spine involvement are rheumatoid arthritis (RA), spondyloarthritis (SpA), and juvenile idiopathic arthritis (JIA). The clinical symptoms of cervical spine pathologies are often nonspecific or absent; therefore, imaging plays a crucial diagnostic role. RA is the most prevalent autoimmune disease; it often leads to cervical spine instability and subsequent myelopathy. In SpA, due to new bone formation, the characteristic lesions include syndesmophytes, parasyndesmophytes, and bone ankylosis, but instabilities are rare. In JIA, early apophyseal bone ankylosis is characteristic, in addition to impaired spinal growth. The aim of this review article is to discuss the imaging pathologies found in patients with RA, SpA, and JIA in the early and advanced stages. This knowledge would be helpful in the proper diagnosis and treatment of these diseases.
34569129 The effect of progressive muscle relaxation on sleep quality and fatigue in patients with 2021 Sep 26 AIMS: The aim of this study was to investigate the effects of progressive muscle relaxation on sleep quality and fatigue in patients with rheumatoid arthritis. METHODS: This randomized controlled study was conducted with 72 patients with rheumatoid arthritis who applied to the rheumatology outpatient clinic of a university hospital between January and May 2018. The data were collected using the Patient Information Form, Pittsburgh Sleep Quality Index and Fatigue Severity Scale. After the patients in the intervention group completed the forms, patients were given training with regard to the application of progressive muscle relaxation which they subsequently performed, and the Pittsburgh Sleep Quality Index and Fatigue Severity Scale forms were repeated after 6 weeks. RESULTS: After performing progressive muscle relaxation for 6 weeks, the total score of the Pittsburgh Sleep Quality Index and the fatigue score decreased among patients in the intervention group; no change was observed among the patients in the control group. A statistical difference was found between the two groups in terms of the Pittsburgh Sleep Quality Index's and Fatigue Severity Scale's mean scores. CONCLUSION: Progressive muscle relaxation can be recommended to enhanced sleep quality and reduce fatigue in patients with rheumatoid arthritis.
34158259 Red Cell Distribution Width and Mean Platelet Volume in Rheumatoid Arthritis Patients: Its 2021 Jun 19 INTRODUCTION: Hemogram parameters have been recently proposed as markers of inflammation in various studies from different parts of the world. Two of these hemogram parameters are red cell distribution width (RDW) and mean platelet volume (MPV). AIM: To evaluate the relation between RDW and MPV with disease activity of rheumatoid arthritis. To assess whether RDW and MPV can be used to follow disease activity in RA patients. METHODS: This is an observational cross-sectional study that was carried out on 60 rheumatoid arthritis patients who fulfilled the ACR/EULAR2010 classification criteria of RA attending to Rheumatology and Rehabilitation inpatient and outpatient clinics at Zagazig University Hospitals. All cases were subjected to full history taking, clinical examination, and laboratory investigations; differential complete blood picture (CBC), acute phase reactants (CRP and ESR), rheumatoid factor (RF) and anti-cyclic-citrullinated peptide (anti-CCP) antibodies. Disease activity was measured by disease activity score 28 (DAS28). RESULTS: The cut-off levels of RDW and MPV were 14.85 and 11.25. Patients with RDW>14.85 had higher Disease Activity Score 28 (DAS28; p=0.0003), ESR (p=0.0001) and CRP (p=0.0001). RDW was positively correlated with disease activity markers (ESR, CRP and DAS28) in rheumatoid arthritis patients. But, DAS28 was not different between patients with MPV>11.25 and <11.25. CONCLUSION: RDW was strongly correlated with disease activity. Also, RDW was better than ESR and CRP in detecting RA disease activity. According to these findings we suggest that RDW can be used in clinics to follow disease activity. In addition, RDW is widely available; as it's usually included in routine complete blood picture and there will be no need for further cost.
34820064 ABO and Rh blood groups in patients with lupus and rheumatoid arthritis. 2021 Fall BACKGROUND: Systemic lupus erythematous (SLE) and rheumatoid arthritis (RA) are autoimmune diseases in which the antigen-antibody system plays an important role. As blood group and Rh are determined by the presence or absence of antigens on the surface of red blood cells (RBCs), we aimed to determine the distribution of ABO and Rh blood groups in SLE and RA patients and its association with disease manifestations. METHODS: This short communication is based on a study that was conducted on 434 SLE and 828 RA patients. We evaluated the distribution of ABO and Rh blood groups in RA and SLE patients. RESULTS: This study projected that in lupus patients, Coombs-positive autoimmune hemolytic anemia and arthritis were more common among the B blood type and Rh-positive group, respectively. Furthermore, there was no relation between ABO and Rh blood group and rheumatoid factor (RF) and anti-Cyclic Citrullinated Peptide (anti-CCP) seropositivity. Moreover, there was no difference in distribution of blood groups in RA and SLE patients. CONCLUSION: The higher frequency of blood group B in hemolytic anemia, and positive Rh in arthritis in lupus patients, develop the hypothesis of probable role of ABO blood group antigen in some manifestations of lupus.
34729333 Infrared Thermography and Ultrasonography of the Hands in Rheumatoid Arthritis Patients. 2021 Jul Ultrasonography (US) and power Doppler US (PDUS) are used worldwide for diagnosing rheumatoid arthritis (RA). Superb microvascular imaging (SMI) is a good tool for evaluating inflammatory activity. Thermal imaging is a noncontact, noninvasive procedure using skin temperature measurement. We report a case wherein the thermal and ultrasound images of the hand are compared and evaluated for inflammatory activity in patients with RA. Case: US imaging of the left hand of a 75-year-old woman with RA revealed a hypoechoic lesion of the left wrist joint. PDUS and SMI evaluated blood flow according to the blood flow at Grade 2. The temperature of the hypoechoic lesion with high blood flow was higher than that of the same location on the opposite side. This study shows that combining thermal and blood flow images may be useful for detecting inflammatory activity levels in RA patients.
32876781 Characteristics, evolution, and outcome of patients with non-infectious uveitis referred f 2021 Apr OBJECTIVE: To investigate the characteristics, evolution, and visual outcome of non-infectious uveitis. METHODOLOGY: Records of 201 patients with non-infectious uveitis (136 (67.7%) males and 84 (41.8%) juvenile-onset (≤ 16 years)) were retrospectively reviewed. Data were analyzed through Kruskal-Wallis and Mann-Whitney, chi-square (χ(2)) tests, and logistic regression. RESULTS: The median disease and follow-up durations were 36 (interquartile range (IQR) 24-70) and 24 (IQR 10-36) months, respectively. Fifty-eight (28.9%) patients had persistently idiopathic uveitis, and 143 (71.1%) were associated with rheumatic diseases, of whom uveitis heralded, coincided with, and succeeded the rheumatic manifestation(s) in 62/143 (43.4%), 37/143 (25.9%), and 44/143 (30.7%) patients, respectively. Established rheumatic diseases were Behçet's disease (103/201 (51.2%)), juvenile idiopathic arthritis (13/201 (6.5%)), sarcoidosis (8/201 (4%)), seronegative spondyloarthropathy (7/201 (3.5%)), and Vogt-Koyanagi-Harada (7/201 (3.5%)), and other diagnoses were present in 5/201 (2.5%) patients. Patients with idiopathic uveitis were characterized by a juvenile-onset (p < 0.001), lower male predominance (p = 0.01), prevalent granulomatous (p < 0.001), and anterior (p = 0.001) uveitis. The median visual acuity at last visit was 0.3 (IQR 0.05-0.6). Visual loss was present in 45/201 (22.3%) patients (36/201 (17.9%) unilateral and 9/201 (4.4%) bilateral). Apart from a longer disease duration (p = 0.002), lower educational level (p = 0.03), and prevalent panuveitis (p < 0.001), visual loss was not associated with any other studied ocular or extra-ocular characteristics. CONCLUSION: Behçet's disease (51.2%) and idiopathic uveitis (28.9%) were the most prevalent causes of non-infectious uveitis in our study. Visual loss (22.3%) was associated with a longer disease duration, lower education level, and prevalent panuveitis. Key Points • Most common causes of uveitis referred to rheumatologists were Behçet's disease and idiopathic uveitis. • Several rheumatic diseases initially presented only with uveitis, more commonly in adult and male patients. • Panuveitis was more frequent among patients with an established rheumatic disease, whereas granulomatous uveitis was uncommon. • Longer disease duration and presence of panuveitis were independently associated with visual loss.
34868575 Hematological parameters as a predictor of disease remission in patients with rheumatoid a 2021 Dec BACKGROUND: Alterations in the hematological profile have been linked to disease activity in rheumatoid arthritis (RA). We aimed to evaluate the levels of hematological parameters in different phases of rheumatoid arthritis (RA) and determine whether hematological parameters could be used to predict RA remission. MATERIALS AND METHODS: The medical records of 365 RA patients were reviewed. Multivariate logistic regression analysis was used to compare hematological parameters among RA patients who were categorized into 4 groups according to disease activity: disease remission or low, moderate or high disease activity. Receiver operating characteristic curves were used to determine the predictive performances of significant parameters for RA remission. RESULTS: Complete data were obtained from 325 patients. The 4 groups of patients had different levels of hemoglobin (Hb), red blood cell, white blood cell, and platelet values. In multivariate analysis, Hb level, neutrophil-to-lymphocyte ratio (NLR), and mean platelet volume (MPV) were independent factors associated with disease activity. The combination of these 3 parameters yielded a sensitivity of 95.2% (95% confidence interval [CI] 88.7-98.2), specificity of 23.6% (95% CI 18.3-29.9), positive predictive value of 37.3% (95% CI 31.6-43.4), and negative predictive value of 91.2% (95% CI 80.0-96.7) in predicting disease remission. CONCLUSION: Hb level, NLR and MPV were independently associated with RA disease activity. The high sensitivity and negative predictive value of the model consisting of Hb level, NLR and MPV may serve as a simple and inexpensive tool to identify patients who are less likely to have disease remission.
33554176 Midterm clinical outcomes of reverse shoulder arthroplasty in Japanese patients with rheum 2021 Jan BACKGROUND: Reverse shoulder arthroplasty normally has adequate functional outcomes in patients with cuff tear arthropathy. The present study aimed to investigate the midterm clinical outcomes of reverse shoulder arthroplasty in Japanese patients with rheumatoid arthritis. METHODS: Between July 2014 and May 2016, reverse shoulder arthroplasty was performed in 14 rheumatic shoulders with joint destruction and rotator cuff tears. The range of motion, Constant score, and Shoulder36, which is a patient-reported outcome measure, were compared preoperatively and postoperatively. The prevalence of subscapular notching, subscapular osteophytes, postoperative fractures, and stress shielding of the humeral stem were evaluated by X-ray. RESULTS: Range of motion significantly improved from 77 to 122 degrees in flexion and from 67 to 111 degrees in abduction at four years. The Constant score significantly improved from 27 to 62, and each domain of Shoulder36 also significantly increased at four years. There was no dislocation, infection, or loosening of the prosthesis. Three shoulders presented scapular notching, and three cemented humeral stems showed stress shielding in the proximal humeral cortical bone. CONCLUSION: Reverse shoulder arthroplasty performed in Japanese patients with rheumatoid arthritis not only decreased the pain and improved the function of the shoulder joint but also significantly improved patients' health and activity of daily living in midterm results.
34683006 Should We Be Screening for and Treating Periodontal Disease in Individuals Who Are at Risk 2021 Oct 5 There is increasing evidence supporting an association between periodontal disease (PD) and rheumatoid arthritis (RA), both mechanistically and clinically. Trials have shown that treating PD in people with RA may improve RA disease activity. Patients with musculoskeletal symptoms without arthritis, who test positive for cyclic-citrullinated protein antibodies, are at risk of RA (CCP+ at-risk), with seropositivity preceding arthritis onset by months or years. Importantly, there is evidence to suggest that periodontal inflammation may precede joint inflammation in CCP+ at-risk and, therefore, this could be a trigger for RA. There has been increased research interest in RA prevention and the phenotyping of the pre-RA disease phase. This review will examine the merits of identifying individuals who are CCP+ at-risk and performing screening for PD. In addition, we discuss how PD should be treated once identified. Finally, the review will consider future research needed to advance our understanding of this disease association.
34278004 Screening for sarcopenia and obesity by measuring thigh muscle and fat thickness by ultras 2021 Jun OBJECTIVES: Sarcopenia is relatively common in rheumatoid arthritis (RA) patients. Thicknesses of the quadriceps muscle and fat are easily measured by ultrasound (US) and are known to be related to skeletal muscle mass and fat mass, respectively. METHODS: Eighty-four patients enrolled in the prospective correlation research of sarcopenia, skeletal muscle, and disease activity in rheumatoid arthritis study (UMIN000023744) underwent US examinations of anterior thigh muscle thickness (MT) and fat thickness (FT). Muscle and body fat (BF) mass were also examined by a body composition analyzer. Whether MT and FT were related to sarcopenia and obesity was examined. RESULTS: MT was significantly lower in RA patients with sarcopenia than in those without (23.8 vs 28.2 mm, P = 0.001). MT was related to sarcopenia (men: r = 0.56, P = 0.02, women: r = 0.32, P = 0.01). The cut-off value of MT for sarcopenia was 24.7 mm in men and 19.7 mm in women on receiver operating characteristic curve analyses. FT was correlated with BF percentage (%BF; men: r = 0.66, P < 0.01, women: r = 0.62, P < 0.001), which was estimated by 2.04xFT+8.53 in men and 1.2xFT+17.42 in women by a simple linear regression model. This means that FT ≥ 8.1 mm in men and FT ≥ 14.6 mm in women indicated obesity. CONCLUSIONS: US examination of the anterior thigh was useful to detect sarcopenia and obesity in RA patients.
34515803 Association Between Peripheral Eosinophilia and Clinical Characteristics of Adult-onset St 2021 Sep 28 Persistent eruption occurs in a subset of patients with adult-onset Still's disease. In our experience, a considerable proportion of these patients present with peripheral eosinophilia. The aims of this study were to summarize the clinical and histological features of patients with adult-onset Still's disease with persistent eruption in the current study cohort, and to assess the association between peripheral eosinophil levels and disease characteristics. A total of 21 patients with adult-onset Still's disease with persistent eruption were included in this retrospective study. Koebner signs, an important diagnostic clue, were found in 85.7% of patients. The proportion of patients presenting with eosinophilia within the disease course was 57.1%. Skin histology revealed infiltration of eosinophils in 90.5% of patients. Peripheral eosinophil levels were positively associated with involved body surface area. Patients with normal peripheral eosinophil counts were more likely to achieve complete remission than those with abnormal peripheral eosinophil counts. Eosinophils may be involved in the pathogenesis of skin eruption. Abnormal peripheral eosinophil counts in these patients may indicate a more refractory disease course.
32788403 Successful treatment of interstitial pneumonitis with anakinra in a patient with adult-ons 2021 Nov A 29-year-old African woman with active adult-onset Still's disease (AOSD) that developed at the end of 2018 presented to our hospital in September 2019 with pleuritic right-sided pain and respiratory insufficiency of almost a month's duration, which had failed to respond to high-dose corticosteroid and antibiotic treatment. A thoracic CT revealed right pleural effusion, multiple consolidations and pulmonary collapse. Besides pulmonary symptoms, the patient had arthralgia, fever, a salmon-coloured rash, leucocytosis and rising inflammatory markers. After an AOSD flare diagnosis was established, intravenous methylprednisolone and painkillers were administered. Due to the severity of the pleural effusion and the lack of response to previous treatments, subcutaneous anakinra was started. Two days after the first dose the patient had almost fully recovered. The success of this case points out the potential effectiveness of anakinra in the prevention of a pulmonary failure and the treatment of a severe intermittent polycyclic pattern of AOSD.
35018034 Clinical Profile and Comorbidities Associated with Rheumatoid Arthritis Patients in Sudair 2021 Nov BACKGROUND: Rheumatoid arthritis (RA) is a chronic, debilitating condition that has a significant effect on the lives of patients, their families, and society at large. AIMS: The aim is to determine the clinical profile and any comorbidities associated with RA patients in the Sudair region of Saudi Arabia. SUBJECTS AND METHODS: Sixty patients were included in this cross-sectional observational study, both newly or already diagnosed with RA, fulfilling the 2010 American College of Rheumatology/European League Against Rheumatism Classification Criteria for RA. They were followed up in the rheumatology clinic in King Khalid Majmaah Hospital in the Majmaah province from January 2017 to December 2020. RESULTS: The subjects' mean age was 47.87 ± 11.55 years, 52 female and 8 male (female-to-male ratio 6.5:1). About 23.3% of patients with RA had positive family history. The main comorbidities and associated diseases were hypertension (18.3%) and hypothyroidism (15%). The most frequently involved joints were the wrist, metacarpophalangeal, proximal interphalangeal, elbow, and knee joints. Subjects were positive in 66.7% for rheumatoid factor and 78.3% for anti-cyclic citrullinated peptide. Both markers were positive in 60% of the patients. CONCLUSION: Approximately one-quarter of the studied group had a family history of RA. Hypertension followed by hypothyroidism was the most common comorbidities reported in our study.
34527929 A cross-sectional study of sexual dysfunction in chinese mainland female patients with rhe 2021 Jun OBJECTIVES: This study aims to investigate the effects of rheumatoid arthritis (RA) on Chinese mainland female patients' sexual function compared with healthy subjects and to determine the risk factors of sexual dysfunction. PATIENTS AND METHODS: A total of 151 female RA patients (mean age: 46.3±8.6 years) and 146 healthy female controls (mean age 45.7±7.6 years) were included in this cross-sectional study whose data were collected consecutively by questionnaires between November 2017 and June 2019. Data were collected by using demographics, disease-related information, Female Sexual Function Index, Dyadic Adjustment Scale, Medical Coping Modes Questionnaire, other psychological parameters and the Short Form-36. RESULTS: Our results showed that the prevalence of female sexual dysfunction was 67.5% in RA patients, which was significantly higher than the controls (54.1%) (p<0.05). Body mass index, resignation coping style, physical component summary, marital dysfunction and postmenopausal status were significant correlation factors by backward stepwise binary logistic regression. CONCLUSION: Rheumatoid arthritis negatively affected sexual function of patients who had considerably impaired sexual function compared to controls.

34283430 Baricitinib. 2022 Jan Baricitinib is a medication used in the management and treatment of severe rheumatoid arthritis. This activity reviews the indications, action, and contraindication for Baricitinib as a valuable agent in managing rheumatoid arthritis in a clinical setting.
33897289 Shared epitope and polymorphism of MICA and NKG2D encoding genes in Greek and Polish patie 2021 The present study aimed to analyse and compare the distribution of MICA (rs1051792) and NKG2D/KLRK1 (rs1154831, rs1049174, rs2255336) polymorphisms in 61 Greek and 100 Polish patients with rheumatoid arthritis in relation to the presence of the HLA-DRB1 shared epitope and clinical parameters. Genotyping of selected polymorphism was performed using real-time PCR. HLA-DRB1 shared epitope alleles segregated differently in Greek and Polish patients but in both populations were detected in over 60% of cases. The rs1051792-A variant was more common among SE-positive Polish patients (p = 0.003) while the rs1049174-G allele was more frequently observed in Greeks than in Poles (p < 0.001). Moreover, among Greek patients, the rs1051792-GG homozygotes more frequently presented with anti-CCP antibodies and rheumatoid factor (RF), while carriers of the rs1049174-G variant and rs1154831-CC homozygotes were characterized by lower disease activity scores (p < 0.05 in all cases). These results imply that, in addition to the HLA-DRB1 SE alleles, MICA and NKG2D polymorphisms may also play a role in rheumatoid arthritis.
33819944 Nonrheumatoid Retro-Odontoid Pseudotumors: Characteristics, Surgical Outcomes, and Time-De 2021 Mar OBJECTIVE: Although a retro-odontoid pseudotumor associated with rheumatoid arthritis is a well-known clinical entity, little is known about retro-odontoid pseudotumors not associated with rheumatoid arthritis due to their rarity. METHODS: Between 2006 and 2019, consecutive patients with nonrheumatoid pseudotumors were included and retrospectively compared with patients with rheumatoid pseudotumors. RESULTS: Nineteen patients had nonrheumatoid pseudotumors (mean age, 73 ± 6 years; male, 53%). All had cervical lesions including ossified anterior and posterior longitudinal ligaments with a history of cervical surgery in 5. The mean thickness of the pseudotumors at diagnosis was 8.1 mm (range, 4.2-17.2 mm). Pseudotumor thickness had a significant negative correlation with the atlantodental interval (p = 0.008) and the subaxial range of motion (p = 0.049). In comparison with 7 rheumatoid pseudotumor patients, nonrheumatoid pseudotumor patients were older (p = 0.042), had a higher proportion of males (p = 0.023), had a smaller atlantodental interval (p = 0.007), and had larger pseudotumors at diagnosis (p = 0.030). Of the 19 patients, 18 received posterior fixation with or without C1 laminectomy, while the other received C1 laminectomy alone. The percent pseudotumor thickness at follow-up to those at diagnosis was 91%, 77%, 68%, 46%, 58%, and 49% at 1, 3, 6, 12, 24, and 36 months after surgery, respectively. CONCLUSION: This study revealed markedly clinical and radiological differences between nonrheumatoid and rheumatoid pseudotumors. The main etiology for nonrheumatoid pseudotumors was subaxial cervical degeneration and ossified lesions. There were good outcomes following posterior fixation and time-dependent pseudotumor regression within 12 months.
