RESUMEN

Psoriatic arthritis (PsA) is a chronic inflammatory arthritis associated with psoriasis, characterized by heterogeneous clinical manifestations and variable disease progression. Ultrasonography has emerged as a valuable tool in the diagnosis and monitoring of PsA, providing real-time visualization of joint and soft tissue abnormalities. This review highlights recent advancements in ultrasonographic techniques for the assessment of PsA, including the identification of typical features, the role of power Doppler imaging in detecting active inflammation, and the potential of ultrasound for guiding treatment decisions. Additionally, we discuss the utility of ultrasound in assessing treatment response and monitoring disease progression in patients with PsA, with a focus on novel imaging modalities. By elucidating the evolving role of ultrasonography in PsA management, this article aims to enhance clinicians' understanding of its utility in facilitating early diagnosis, optimizing treatment strategies, and improving patient outcomes.

RESUMEN

Rheumatoid arthritis is a chronic autoimmune disease that can affect different organs beyond the joints. Ocular involvement includes keratoconjunctivitis sicca, peripheral ulcerative keratitis (PUK), episcleritis, scleritis, anterior uveitis, and corneal impairment. The most severe form of scleritis, scleromalacia perforans, is an aggressive ophthalmic manifestation that can potentially lead to blindness, usually occurring in late stages of disease. We report a case of an elderly woman in which this severe ocular manifestation occurred early on disease onset, differing from most of the previously reported cases of scleromalacia perforans. Ocular symptoms started concomitantly with the polyarthritis and other extra-articular manifestations, including rheumatoid nodules and vasculitic skin lesions. Ocular disease progressed due to patient's loss to follow-up, requiring pulse therapy with methylprednisolone. However, despite treatment, right eye enucleation was required due to melting of the corneal patch with uveal exposition. The patient was then treated with rituximab with improvement of systemic disease. The present case reinforces that, although rare, this complication is severe and must be promptly diagnosed and aggressively treated to improve prognosis of ocular and systemic RA.

RESUMEN

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease that affects exocrine glands, mainly the salivary and lacrimal glands, leading to the development of sicca symptoms. Patients with pSS may also present with extraglandular manifestations, including lung involvement, estimated to occur in 9-24% of cases. Shrinking lung syndrome (SLS) is an uncommon respiratory complication primarily associated with systemic lupus erythematosus, with a prevalence of approximately 1% in these patients. It typically manifests as dyspnea, pleuritic chest pain, lung volume reduction, and a restrictive pattern on respiratory function tests. Cases reporting SLS with other connective tissue diseases, including pSS, are even rarer. Herein, we describe a case of a 57-year-old woman with a 10-year history of pSS who presented with dyspnea and pleuritic chest pain. After evaluation, the patient was diagnosed with SLS based on clinical, radiologic, laboratorial, and electrophysiologic characteristics. In addition, we identified and analyzed previously published cases of SLS in pSS. Treatment includes corticosteroids, immunosuppressants, and respiratory muscle training. This study highlights the importance of considering SLS in the differential diagnosis of patients with pSS and respiratory symptoms.

RESUMEN

Sjogren's syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration of the exocrine glands and other organs, associated with sicca syndrome but also with systemic involvement with varying degrees of severity. Despite their importance, some systemic manifestations, mainly liver, gastrointestinal, and pancreatic are not routinely evaluated. To address these manifestations, the Sjögren's Syndrome Committee of the Brazilian Society of Rheumatology conducted a broad systematic review of the literature on studies investigating prevalence and diagnosis of these symptoms in Sjogren´s patients and made recommendations based on the findings. Agreement between the experts was achieved using the Delphi method. This is the second part of this guideline, providing 6 recommendations for liver, gastrointestinal, and pancreatic care of SS patients.

RESUMEN

The determination of durability and vaccine-associated protection is essential for booster doses strategies, however data on the stability of SARS-CoV-2 immunity are scarce. Here we assess anti-SARS-CoV-2 immunogenicity decay and incident cases six months after the 2nd dose of Sinovac-CoronaVac inactivated vaccine (D210) in 828 autoimmune rheumatic diseases patients compared with 207 age/sex-balanced control individuals. The primary outcome is the presence of anti-S1/S2 SARS-CoV-2 IgG at 6 months compared to 6 weeks after 2nd vaccine dose for decay evaluation. Secondary outcomes are presence of neutralizing antibodies, percent inhibition by neutralizing, geometric mean titers and cumulative incident cases at 6 months after 2nd dose. Anti-S1/S2 IgG positivity and titers reduce to 23.8% and 38% in patients (p < 0.001) during the six-month follow up and 20% and 51% in controls (p < 0.001), respectively. Neutralizing antibodies positivity and percent inhibition declines 41% and 54% in patients (p < 0.001) and 39.7% and 47% in controls (p < 0.001). Multivariate logistic regression analysis show males (OR = 0.56;95% CI0.40-0.79), prednisone (OR = 0.56; 95% CI0.41-0.76), anti-TNF (OR = 0.66;95% CI0.45-0.96), abatacept (OR = 0.29; 95% CI0.15-0.56) and rituximab (OR = 0.32;95% CI0.11-0.90) associate with a substantial reduction in IgG response at day 210 in patients. Although cellular immunity was not assessed, a decrease of COVID-19 cases (from 27.5 to 8.1/100 person-years; p < 0.001) is observed despite the concomitant emergence and spread of the Delta variant. Altogether we show a reduction in immunity 6-months of Sinovac-CoronaVac 2nd dose, particularly in males and those under immunosuppressives therapies, without a concomitant rise in COVID-19 cases.

RESUMEN

INTRODUCTION: There is no study specifically focused on SARS-CoV-2 vaccine in primary Sjögren's syndrome (pSS). OBJECTIVES: To assess the immunogenicity, safety, possible effects on disease activity, and autoantibody profile of the Sinovac-CoronaVac vaccine in pSS. METHODS: Fifty-one pSS patients and 102 sex- and age-balanced controls without autoimmune diseases were included in a prospective phase 4 trial of the Sinovac-CoronaVac vaccine (two doses 28 days apart, D0/D28). Participants were assessed in three face-to-face visits (D0/D28 and six weeks after the 2nd dose (D69)) regarding adverse effects; clinical EULAR Sjögren's Syndrome Disease Activity Index (clinESSDAI); anti-SARS-CoV-2 S1/S2 IgG (seroconversion (SC) and geometric mean titers (GMT)); neutralizing antibodies (NAb); and pSS autoantibody profile. RESULTS: Patients and controls had comparable female sex frequency (98.0% vs. 98.0%, p = 1.000) and mean age (53.5 ± 11.7 vs. 53.4 ± 11.4 years, p = 0.924), respectively. On D69, pSS patients presented moderate SC (67.5% vs. 93.0%, p < 0.001) and GMT (22.5 (95% CI 14.6-34.5) vs. 59.6 (95% CI 51.1-69.4) AU/mL, p < 0.001) of anti-SARS-CoV-2 S1/S2 IgG but lower than controls, and also, moderate NAb frequency (52.5% vs. 73.3%, p = 0.021) but lower than controls. Median neutralizing activity on D69 was comparable in pSS (58.6% (IQR 43.7-63.6)) and controls (64% (IQR 46.4-81.1)) (p = 0.219). Adverse events were mild. clinESSDAI and anti-Ro(SS-A)/anti-La(SS-B) levels were stable throughout the study (p > 0.05). CONCLUSION: Sinovac-CoronaVac vaccine is safe in pSS, without a deleterious impact on disease activity, and has a moderate short-term humoral response, though lower than controls. Thus, a booster dose needs to be studied in these patients. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04754698. Key Points • Sinovac-CoronaVac vaccine is safe in pSS, without a detrimental effect on systemic disease activity, and has a moderate short-term humoral response • A booster dose should be considered in these patients.

RESUMEN

OBJECTIVE: To determine the immunogenicity of the third dose of CoronaVac vaccine in a large population of patients with autoimmune rheumatic diseases (ARD) and the factors associated with impaired response. METHODS: Adult patients with ARD and age-balanced/sex-balanced controls (control group, CG) previously vaccinated with two doses of CoronaVac received the third dose at D210 (6 months after the second dose). The presence of anti-SARS-CoV-2 S1/S2 IgG and neutralising antibodies (NAb) was evaluated previously to vaccination (D210) and 30 days later (D240). Patients with controlled disease suspended mycophenolate mofetil (MMF) for 7 days or methotrexate (MTX) for 2 weekly doses after vaccination. RESULTS: ARD (n=597) and CG (n=199) had comparable age (p=0.943). Anti-S1/S2 IgG seropositivity rates significantly increased from D210 (60%) to D240 (93%) (p<0.0001) in patients with ARD. NAb positivity also increased: 38% (D210) vs 81.4% (D240) (p<0.0001). The same pattern was observed for CG, with significantly higher frequencies for both parameters at D240 (p<0.05). Multivariate logistic regression analyses in the ARD group revealed that older age (OR=0.98, 95% CI 0.96 to 1.0, p=0.024), vasculitis diagnosis (OR=0.24, 95% CI 0.11 to 0.53, p<0.001), prednisone ≥5 mg/day (OR=0.46, 95% CI 0.27 to 0.77, p=0.003), MMF (OR=0.30, 95% CI 0.15 to 0.61, p<0.001) and biologics (OR=0.27, 95% CI 0.16 to 0.46, p<0.001) were associated with reduced anti-S1/S2 IgG positivity. Similar analyses demonstrated that prednisone ≥5 mg/day (OR=0.63, 95% CI 0.44 to 0.90, p=0.011), abatacept (OR=0.39, 95% CI 0.20 to 0.74, p=0.004), belimumab (OR=0.29, 95% CI 0.13 to 0.67, p=0.004) and rituximab (OR=0.11, 95% CI 0.04 to 0.30, p<0.001) were negatively associated with NAb positivity. Further evaluation of COVID-19 seronegative ARD at D210 demonstrated prominent increases in positivity rates at D240 for anti-S1/S2 IgG (80.5%) and NAb (59.1%) (p<0.0001). CONCLUSIONS: We provide novel data on a robust response to the third dose of CoronaVac in patients with ARD, even in those with prevaccination COVID-19 seronegative status. Drugs implicated in reducing immunogenicity after the regular two-dose regimen were associated with non-responsiveness after the third dose, except for MTX. Trial registration number NCT04754698.

RESUMEN

BACKGROUND: Coronary artery aneurysm (CAA) in an uncommon condition usually associated with atherosclerosis, but systemic vasculitides constitute important differential diagnoses. A less recognized cause of CAA, tuberculosis (TB) has also been noted to occur simultaneously in patients with such vascular abnormalities. CASE REPORT: A 60-year-old female presented to the Emergency Department with a non-ST segment elevation myocardial infarction. Angiography demonstrated segmental aneurysms of the left anterior descending coronary artery. Shortly after, she was also diagnosed with cutaneous TB, and treatment was promptly initiated. Reevaluation conducted several months later demonstrated that levels of inflammation markers had significantly decreased. New catheterization of coronary arteries evidenced complete resolution of coronary aneurysm images. CONCLUSION: Due to the clinical and radiologic resolution with only TB treatment, as well as lack of evidence supporting atherosclerotic or vasculitic etiologies, TB can be considered a possible contributor to aneurysm formation in this case. Prospective studies are necessary to reliably demonstrate causality between TB infection and CAA.

RESUMEN

The use of electroconvulsive therapy in case of catatonia due to systemic lupus erythematosus refractory in treatment with immunosuppressant is rare. Therefore, we report a case of catatonia due to systemic lupus erythematosus treated with electroconvulsive therapy as an adjuvant to cyclophosphamide treatment. A 34-year-old female patient diagnosed with systemic lupus erythematosus attended the rheumatology outpatient clinic with a history of catatonia for 8 weeks and laboratory tests revealed high titers of anti-ds DNA positive anti-RNP and polyclonal gammopathy. cyclophosphamide pulse therapy was scheduled in association with electroconvulsive therapy, in 12 sessions, twice a week. The patient evolved with significant clinical improvement after 6 sessions of electroconvulsive therapy and 2 pulses of cyclophosphamide, with negative anti-ds DNA and normalization of gamma globulin levels. Thus, electroconvulsive therapy should be considered as adjuvant therapy in severe cases of neuropsychiatric systemic lupus erythematosus, including catatonia, especially in those with relapses and poor response to immunosuppressant and psychotropic drugs.

RESUMEN

Sjogren's syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration of the exocrine glands and other organs. Women with SS often experience gynecological symptoms due to the disease and need extra care regarding their sexual activity, reproductive health and during pregnancy, conditions that are not properly conducted in the clinical practice. To cover this gap, a panel of experts from the Brazilian Society of Rheumatology conducted a systematic review and meta-analysis on the identification of symptoms, diagnosis, monitoring, prognosis, and treatment of these manifestations. A Focus Group meeting was held and included experts in the field and methodologists, based on a previously developed script, with themes related to the objective of the study. The most important topics were summarized and 11 recommendations were provided.

RESUMEN

OBJECTIVE: To evaluate the effects of a low-load resistance training program associated with partial blood-flow restriction in patients with rheumatoid arthritis (RA). METHODS: Forty-eight women with RA were randomized into 1 of 3 groups: high-load resistance training (HL-RT; 70% 1 repetition maximum [1RM]), low-load resistance training (30% 1RM) with partial blood-flow restriction training (BFRT), and a control group. Patients completed a 12-week supervised training program and were assessed for lower-extremity 1RM, quadriceps cross-sectional area (CSA), physical function (timed-stands test [TST], timed-up-and-go test [TUG], and Health Assessment Questionnaire [HAQ]), and quality of life (Short Form 36 health survey [SF-36]) at baseline and after the intervention. RESULTS: BFRT and HL-RT were similarly effective in increasing maximum dynamic strength in both leg press (22.8% and 24.2%, respectively; P < 0.0001 for all) and knee extension (19.7% and 23.8%, respectively; P < 0.0001 for all). Quadriceps CSA was also significantly increased in both BFRT and HL-RT (9.5% and 10.8%, respectively; P < 0.0001 for all). Comparable improvements in TST (11.2% and 14.7%; P < 0.0001 for all) and TUG (-6.8% [P < 0.0053] and -8.7% [P < 0.0001]) were also observed in BFRT and HL-RT, respectively. Improvements in both groups were significantly greater than those of the control group (P < 0.05 for all). SF-36 role physical and bodily pain and HAQ scores were improved only in BFRT (45.7%, 22.5%, and -55.9%, respectively; P < 0.05 for all). HL-RT resulted in 1 case of withdrawal and several cases of exercise-induced pain, which did not occur in BFRT. CONCLUSION: BFRT was effective in improving muscle strength, mass, function, and health-related quality of life in patients with RA, emerging as a viable therapeutic modality in RA management.

RESUMEN

BACKGROUND/OBJECTIVE: Recent studies have indicated that cardiac autonomic dysfunction is an early sign of cardiovascular impairment in rheumatoid arthritis (RA). Previous studies have mainly focused on resting assessments; however, analysis of heart rate (HR) responses to exercise might provide additional information on cardiac autonomic dysfunction in this disease. Thus, we aimed to assess the HR responses during and after a maximal graded exercise test in patients with RA and healthy controls (CONs). METHODS: This was a cross-sectional study in which 27 female RA patients and 14 female CONs frequency matched by physical activity, age, and body mass index were compared for HR responses during and after a maximal graded exercise test. RESULTS: Rheumatoid arthritis patients showed reduced chronotropic response (94.3% ± 16.3% vs. 106.1% ± 10.3%, p = 0.02) and lower HR recovery (HRR) at 30 seconds (8.6 ± 6.7 vs. 13.4 ± 5.2 beats/min [bpm], p = 0.02), 60 seconds (16.5 ± 7.8 vs. 24.0 ± 9.9 bpm, p = 0.01), 120 seconds (32.6 ± 9.9 vs. 40.7 ± 12.3 bpm, p = 0.03), and 180 seconds (46.5 ± 12.6 vs. 55.5 ± 13.4 bpm, p = 0.05) post-maximal exercise test when compared with CONs. Moreover, the prevalence of chronotropic incompetence (i.e., failure to reach 80% of the HR-predicted response) and abnormal HRR (i.e., HRR ≤12 bpm) were, respectively, 22.2% and 37.1% in RA patients. CONCLUSIONS: Patients with RA showed reduced chronotropic response to exercise and slower postexercise HRR. These abnormal autonomic responses to exercise indicate the presence of cardiac autonomic dysfunction and increased cardiovascular risk in this population.

RESUMEN

BACKGROUND: Rheumatoid arthritis (RA) is a systemic inflammatory disease associated with cardiovascular risk, but with normal plasma lipids. OBJECTIVE: The aim was to investigate low-density lipoprotein (LDL) and high-density lipoprotein (HDL) metabolism in RA patients using radioactive nanoemulsions resembling an LDL lipid structure (LDE) as metabolic probes. METHODS: Thirty patients with RA, 16 in remission and 14 in high activity, and 30 healthy controls were studied. LDE labeled with (14)C-cholesteryl ester ((14)C-CE) and (3)H-unesterified cholesterol ((3)H-UC) was intravenously injected followed by 24-hour plasma sampling. Fractional clearance rates (FCR, h(-1)) were calculated by compartmental analysis. Lipid transfers to HDL were assayed by incubating plasma samples with a donor nanoemulsion labeled with radioactive lipids; % lipids transferred to HDL were quantified after chemical precipitation. RESULTS: LDL cholesterol, triglycerides, unesterified cholesterol, and oxidized LDL were equal in RA and controls, and HDL cholesterol was even higher in RA. Compared with controls, apolipoprotein B was lower, apolipoprotein A1 was equal, and apolipoprotein E was higher in RA. Decay curves of LDE labels were faster in RA patients than in controls ((14)C-CE: 0.072 ± 0.066 and 0.038 ± 0.027, P = .0115; (3)H-UC: 0.066 ± 0.042 and 0.035 ± 0.039; P < .0044). FCRs were equal in 2 RA subgroups. Transfer of UC, triglycerides, and phospholipids to HDL was equal between RA and controls, but CE transfer was lower in RA. HDL size was smaller in RA patients than in controls (8.5 ± 0.5 nm; 9.2 ± 0.8 nm, P < .0001). CONCLUSION: RA patients were more efficient in removing atherogenic LDL from plasma, as indicated by higher CE and UC FCR, with in lower apolipoprotein B. This was unexpected because of the higher cardiovascular risk in RA.

RESUMEN

The adolescent athletes are at greater risk of low back pain and structural spine injuries. Spondylolysis is responsible for the majority of back pain cases in young athletes, rarely occurring in adults. We report a case of a 13-year-old judo female athlete, who came to our service with 5 months of progressive low back pain during training which was initially attributed to mechanical causes, without any further investigation by imaging methods. At admission, the patient had lumbar deformity, antalgic posture and bilaterally positive unipodalic lumbar hyperextension maneuver. After a research which showed spondyloptosis, the patient underwent surgery. In this article, we discuss, based on this case report, the diagnostic approach to low back pain in young athletes, since the complaint of chronic back pain can be a marker of a structural lesion that may be permanent and bring irreversible functional loss.
