ABSTRACT
INTRODUCTION: Although Rheumatoid Arthritis (RA) extra-articular manifestations (ExtRA) occurrence has been decreasing over time, they are still a major mortality risk factor for patients. OBJECTIVE: To determine the prevalence of ExtRA in a large cohort, and its association with demographic and clinical variables. METHOD: Cross-sectional and observational study, based on a multi-centric database from a prospective cohort, in which 11 public rheumatology centres enrolled RA patients (1987 ARA or 2010 ACR-EULAR). Data collection began in 08-2015, using a single online electronic medical record. Continuous variables were compared using Mann-Whitney U-test, and Fisher's exact test or chi-square test, as appropriate, were used for categorical variables. The level of significance was set at 5% (p < 0.05). RESULTS: 1115 patients were included: 89% women, age [mean ± SD] 58.2 ± 11.5 years, disease duration 14.5 ± 12.2 years, positive Rheumatoid Factor (RF, n = 1108) in 77%, positive anti-cyclic citrullinated peptide (ACPA, n = 477) in 78%. Regarding ExtRA, 334 occurrences were registered in 261 patients, resulting in an overall prevalence of 23.4% in the cohort. The comparison among ExtRA and Non-ExtRA groups shows significant higher age (p < 0.001), disease duration (p < 0.001), RF high titers (p = 0.018), Clinical Disease Activity index (CDAI) (p < 0.001), Disease Activity Index 28 (DAS 28) (p < 0.001), and Health Assessment Questionnaire (HAQ) (p < 0.001) in ExtRA group. Treatment with Azathioprine (p = 0.002), Etanercept (p = 0.049) Glucocorticoids (GC) ('p = 0.002), and non-steroidal anti-inflammatory drugs (NSAIDs) (p < 0.001) were more frequent in ExtRA group. CONCLUSIONS: ExtRA manifestations still show an expressive occurrence that should not be underestimated. Our findings reinforce that long-term seropositive disease, associated with significant disability and persistent inflammatory activity are the key factors related to ExtRA development.

This case-control study analyzed risk factors for symptomatic fractures in a group of 52 patients with systemic sclerosis compared with a group of 104 patients without fractures, matched for sex and age, who were attended at a single systemic sclerosis outpatient clinic from 2010 to 2020. Fractures affected predominantly vertebral (65.4%), rib (13.5%), and hip (7.7%) joints, while the mean age of fracture was 55.3 ± 9.5 years. Age at disease onset, age at diagnosis, disease duration, age at menarche, and age at menopause were similar in both groups, and 58.9% of the patients were menopausal at the time of the fracture. The presence of fractures had a significant association with densitometric osteoporosis (p < 0.001), lower weight (p = 0.032), and bone mineral index (p = 0.044), anti-RNA polymerase III (p = 0.040), use of corticosteroids (p = 0.019), and bisphosphonates (p < 0.001), as well as with densitometric T-scores of lumbar spine (p < 0.001), femoral neck (p = 0.025), and total hip (p = 0.013). Multivariate analysis showed that the variables significantly associated with fractures were high doses of corticosteroids (odds ratio = 4.10; 95% confidence interval = 1.290-13.090; p = 0.017), bisphosphonates (odds ratio = 3.91; 95% confidence interval = 1.699-8.984; p = 0.001), negative anti-Scl70 (OR = 0.34; 95% confidence interval = 0.124-0.943; p = 0.038), and lumbar T-score (odds ratio = 0.39; 95% confidence interval = 0.034-0.460; p = 0.010). In conclusion, symptomatic fractures were associated predominantly with lower bone mineral density of lumbar spine and use of high doses of corticosteroids and bisphosphonates in this cohort.
ABSTRACT
OBJECTIVES: To evaluate the distinct impact of disease modifying antirheumatic drugs (DMARD) combination and monotherapy in immune response to an inactivated SARS-CoV-2 vaccine in patients with rheumatoid arthritis (RA). METHODS: This phase 4 prospective study analysed seroconversion (SC) of anti-SARS-CoV-2 immunoglobulin G (IgG) and neutralising antibodies (NAb) induced by the inactivated vaccine (CoronaVac) in patients with RA in comparison to controls (CG). Disease activity and treatment were also assessed. Only participants with baseline negative IgG/NAb were included. RESULTS: Patients with RA (N=260) and CG (N=104) had comparable median ages (59 years (50-65 years) vs 58 years (49.8-64 years), p=0.483). Patients with RA had moderate but lower SC (61.8% vs 94.2%, p<0.001) and NAb positivity (45% vs 78.6%, p<0.001) in comparison to CG after full vaccination. Baseline disease activity did not influence immunogenicity (p>0.05). After multivariate analyses, factors independently related to reduced SC were: older age (OR=0.79 (0.70-0.89) for each 5-year interval, p<0.001), methotrexate (OR=0.54 (0.29-0.98), p=0.044), abatacept (OR=0.37 (0.19-0.73), p=0.004) and number of DMARD (OR=0.55 (0.33-0.90), p=0.018). Regarding NAb, age (OR=0.87 (0.78-0.96) for each 5-year interval, p=0.007) and prednisone >7.5 mg/day (OR=0.38 (0.19-0.74), p=0.004) were negatively related to the presence of NAb. Further comparison of SC/NAb positivity among RA treatment subgroups and CG revealed that methotrexate/tofacitinib/abatacept/tocilizumab use, in monotherapy or in combination, resulted in lower responses (p<0.05), while tumour necrosis factor inhibitor and other conventional synthetic DMARD interfered solely when combined with other therapies. CONCLUSIONS: Patients with RA under DMARD have a moderate immunogenicity to CoronaVac. We identified that nearly all DMARD combinations have a deleterious effect in immunogenicity, whereas a more restricted number of drugs (methotrexate/tofacitinib/abatacept/tocilizumab) also hampered this response as monotherapy. These findings reinforce the need of a broader approach, not limited to specific drugs, to improve vaccine response for this population. TRIAL REGISTRATION DETAILS: NCT04754698.

OBJECTIVE: To analyse the safety, immunogenicity and factors affecting antibody response to Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) vaccination in patients with SSc. METHODS: This is a phase 4 prospective study within a larger trial of two doses of inactivated SARS-CoV-2 vaccine (CoronaVac) in 51 SSc patients compared with 153 controls. Anti-SARS-CoV-2-IgG and neutralizing antibodies (NAb) were assessed at each vaccine shot (D0/D28) and 6 weeks after the second dose(D69), only in individuals with negative baseline IgG/NAb and those who did not have coronavirus-19(COVID19) during follow-up. Vaccine safety was also assessed in all participants. RESULTS: Patients and controls had comparable median ages [48(38.5-57) vs 48(38-57) years, P =0.945]. Patients had mostly diffuse SSc (68.6%) and the majority (74.5%) had interstitial lung disease. Most patients were under immunosuppressive therapy (72.5%), mainly MMF (52.9%). After full vaccination (D69), anti-SARS-CoV-2-IgG frequency (64.1% vs 94.2%, P < 0.001) and NAb positivity (53.8% vs 76.9%; P =0.006) were moderate, although lower than controls. The first dose response (D28) was low and comparable for both seroconvertion rates (SC) (P =0.958) and NAb positivity (P =0.537). SSc patients under MMF monotherapy vs other (no therapy/other DMARDs) had lower immunogenicity (SC: 31.3% vs 90%, P < 0.001) and NAb(18.8% vs 85%, P < 0.001). Multiple regression analysis confirmed that MMF use, but not disease subtype, is associated with insufficient seroconversion [odds ratio (OR)=0.056(95% CI: 0.009, 0.034), P =0.002] and NAb positivity [OR = 0.047(95% CI: 0.007, 0.036), P =0.002]. No moderate/severe side-effects were observed. CONCLUSION: CoronaVac has an excellent safety profile and moderate response to anti-SARS-CoV-2 vaccine in SSc. Vaccine antibody response is not influenced by disease subtype and is greatly affected by MMF, reinforcing the need for additional strategies to up-modulate vaccine response in this subgroup of patients.

To identify environmental factors (EF) in a large cohort of patients with systemic sclerosis (SSc) analyzing their clinical and laboratory presentation. A cohort of consecutive patients attended at a single Brazilian SSc outpatient clinic was analyzed regarding EF. Data were analyzed according to clinical, demographic and laboratory characteristics, as well as SSc subtype. In a cohort of 662 patients, 70 (10.6%) had known previous exposure to EF, predominantly organic solvents (51.4%), silica (20%), silicone (12.9%) and pesticides (11.4%). In the SSc cohort, patients with EF had a significantly higher frequency of male gender (p < 0.01), African-Brazilian ethnicity (p = 0.01), myopathy (p = 0.02), and pigmentary disorders (p = 0.04), with shorter disease duration (p = 0.01). When SSc subtypes were analyzed separately, there was positive association with male gender in limited (p < 0.01) and diffuse (p < 0.01) SSc, as well as African-Brazilian ethnicity (p = 0.04), severe interstitial lung disease (p < 0.01), myopathy (p = 0.02) and SD pattern at nailfold capillaroscopy (p = 0.01) in limited SSc, and negative association with esophageal hypomotility (p < 0.01) and ANA positivity (p = 0.02) in diffuse SSc. Multiple regression analyses showed that myopathy was independently associated with previous exposure to EF (OR = 2.09; 95% CI 1.15-3.82), especially silica exposure (OR = 3.09; 95% CI 1.67-5.73). This study showed that SSc patients with previous exposure to EF may have some specific clinical characteristics, mainly a higher frequency of myopathy, also showing more severe ILD, preferably in male and African-Brazilian patients, associated with a lower frequency of ANA positivity.

The association between cocaine abuse and systemic sclerosis (SSc) is rarely described. Two new cases of this association are presented: two young adults, after using inhaled cocaine for a few years, were diagnosed with SSc. While a 24 year-old white female patient presented with diffuse SSc with multiple digital ulcers and scleroderma renal crisis (SRC), a 27 year-old male patient presented limited SSc with skin ulcers and digital gangrene, rapidly evolving to death due to massive intestinal hemorrhage. The authors performed a literature search and found only eight previously published cases. The clinical picture of these patients shows a predominance of vascular involvement, including multiple ulcers and SRC. There is no association with specific SSc autoantibodies. The concomitance of alcohol and other drugs abuse, as well as the presence of drug adulterers, complicates a clear understanding of the role of cocaine in SSc patients.

The authors describe the case of a 23-year-old woman who was referred to the rheumatologist due to symmetrical and progressive stiffness, induration, and swelling of arms and thighs at the 12th week of her first gestation. The characteristic clinical aspect of 'peau d'orange', associated to the histopathologic results of the deep biopsy of the skin confirmed the diagnosis of eosinophilic fasciitis. Treatment with oral prednisone, at an initial dose of 1 mg/kg/day, was effective and rapidly tapered to 10 mg/day till the birth of a healthy newborn. A literature review showed only one previous description of pregnancy and eosinophilic fasciitis.
