Portuguese Recommendations for the management of Raynaud's phenomenon and digital ulcers in systemic sclerosis and other connective tissue diseases

Objective: To develop evidence-based recommendations for the non-pharmacological and pharmacological management of Raynaud’s phenomenon (RP) and digital ulcers (DUs) in patients with systemic sclerosis and other immune-mediated connective tissue diseases (CTDs). Methods: A task force comprising 21 rheumatologists, two surgeons (vascular and plastic), two nurses, and one patient representative was established. Following a systematic literature review performed to inform the recommendations, statements were formulated and discussed during two meetings (one online and one in-person). Levels of evidence, grades of recommendation (GoR), and level of agreement (LoA) were determined. Results: Five overarching principles and 13 recommendations were developed. GoR ranged from A to D. The mean ± standard difference (SD) LoA with the overarching principles and recommendations ranged from 7.8±2.1 to 9.8±0.4. Briefly, the management of RP and DUs in patients with CTDs should be coordinated by a multidisciplinary team and based on shared decisions with patients. Nifedipine should be used as first-line therapy for RP and/or DUs. Sildenafil, tadalafil, and/or iloprost IV are second-line options for severe and/or refractory patients with RP and/or DUs. Sildenafil, tadalafil and/or Iloprost IV, should be prescribed for healing and prevention (also including bosentan) of DUs. In patients with RP and/or DUs, non-pharmacological interventions might be considered as add-ons, but there is limited quality and quantity of scientific evidence supporting their use. Conclusions: These recommendations will inform rheumatologists, specialist nurses, other healthcare professionals, and patients about a comprehensive and personalized management of RP and DUs. A research agenda was developed to address unmet needs, particularly for non-pharmacologic interventions.

Pulmonary arterial hypertension in systemic sclerosis: a national inpatient analysis

Objectives: We aim to study the prevalence and epidemiology of pulmonary arterial hypertension in SS, and the impact of PAH on SSc hospitalizations in the United States population. Methods: We utilized the National Inpatient Sample (NIS) from 2016-2019 to obtain adult hospitalizations with the primary/secondary diagnosis of SSc and coexistent PAH (SSc-PAH). Epidemiological variables, mortality rates, and secondary outcomes were studied including pulmonary embolism, atrial flutter, atrial and ventricular fibrillation, pneumonia, sepsis, cardiac arrest and cardiac & renal failure, and ventilator requirement. Healthcare burden was estimated from total hospital charges (THC) and length of stay (LOS). Statistical analysis was performed on STATA 16.1, using linear and logistic regression analyses. Results: Out of 126,685 adult systemic sclerosis hospitalizations, 16.89% had PAH (SSc-PAH). The SSc-PAH group had significantly more females (85.4 % vs. 83.8%) and higher mean age (64.85±13.29 vs. 62.56±14.51). More African Americans were in this group than in the control group (19.5% vs. 14.6, p-value<0.001) while Whites (61.3% vs. 65.6%, p<0.001) and Asians (18.0 % vs. 2.8%, p<0.001) were less common. Charlson comorbidity index was higher for the SSc-PAH population (3.42 vs. 2.94, p-value<0.001). SSc-PAH group had a higher adjusted odds ratio (aOR) for mortality (aOR: 1.39, p<0.001), increased LOS (6.64 vs. 6.0 days, p<0.001) increased THC ($83,813 vs. $71,016, p <0.001). For the SSc-PAH group, there were also significantly higher odds of cardiac failure (aOR 3.13), ventilator requirement (aOR 2.15), cardiac arrest (aOR 1.39), kidney failure (aOR 1.63), pulmonary embolism (aOR 1.84), atrial flutter (aOR 1.86) atrial fibrillation (aOR1.56) and pneumonia (aOR 1.22). No significant difference in ventricular fibrillation, sepsis, or respiratory failure was noted. Conclusion: Pulmonary arterial hypertension in SSc is associated with worse outcomes in terms of mortality and morbidity, and higher healthcare burden compared to SSc without PAH. Also, PAH disproportionately affects White, African American & Asian populations. There remains a pressing need to continue efforts for early diagnosis and management of PAH in SSc patients.

Preconception counseling impact in pregnancy outcomes in patients with spondyloarthritis

Abstract Introduction: Spondyloarthritis (SpA) is a group of chronic inflammatory diseases, often affecting women in reproductive age. These diseases can have a significant impact on the reproductive health of women. Preconception counseling and medication adjustments have shown to reduce flares and improve pregnancy outcomes in women with rheumatoid arthritis. However, in women with SpA data of the impact of preconception counselling on pregnancy outcomes is scarce. The aim of this study is to evaluate that. Methods: In this retrospective multicentric study, data was collected from medical records of women who gave birth from 2020 to 2022. The study included 45 pregnancies, which were divided into two categories whether they received preconception consultation or not. Data was collected on patient characteristics, disease duration, medications used, and preconception counselling. Outcomes were divided into two groups: maternal and fetal outcomes. Results: 30 out of 45 pregnancies (66.67%) had received preconception counselling, having a significantly lower percentage of flares occurring postpartum compared to the non-counselling group (36.6% vs 6.4%, p=0.031) and lower percentage of contraindicated medication during pregnancy (20.0 vs 0.0%, p=0.011). Conclusion: Preconception counselling in women with SpA can increase the likelihood of medication adjustments before pregnancy and decrease the occurrence of flares postpartum. These findings suggest that preconception counselling should be implemented in the management of pregnant women with SpA to improve pregnancy outcomes. Further studies are needed to confirm the effectiveness of preconception counselling and to determine the optimal approach.

Imaging of gout: findings and pitfalls. A pictorial review.

Abstract Gout is the most common crystal arthropathy, accounting for up to 5% of all arthritis. The hallmark of the disease is hyperuricemia with the subsequent deposition of monosodium urate (MSU) crystals in the intra- and extra-articular soft tissues and bones, leading to inflammation of these...
