Background: Juvenile idiopathic arthritis (JIA) comprises a whole spectrum of chronic arthritis starting before 16 years of age. The study aims to explore the clinical and demographic descriptors, treatment, and disease progression of enthesitis-related arthritis (ERA) in comparison with juvenile-onset spondyloarthritis (SpA). Methods: Cross-sectional analysis of consecutive patients in two dedicated clinics, with a single visit and retrospective case-notes review. Arthritis, enthesitis and sacroiliitis were evaluated by scoring disease activity and damage. Continuous variables were reported by median, interquartile range; categorical variables were reported by the frequency comparison of the two groups. Results: Thirty-three cases were included, being 23 (69.7%) with ERA. The median age at diagnosis was 12.5 y (SpA) vs. 9 y (ERA) (p < 0.01); the time from symptom onset to diagnosis was 5.5 y (SpA) vs. 1.5 y (ERA) (p < 0.03). In both groups, the predominant presentation was a single joint or < 5 lower limb joints and asymmetric involvement, with a high frequency of enthesitis. There was a higher frequency of mid-tarsal and ankle synovitis in the ERA group and hip involvement in those with SpA. The comparison of the frequency of spine symptoms at presentation, 30% SpA vs. 21.7% ERA (p = 0.7), was not significant, and radiographic progression to spinal involvement occurred in 43.5% of ERA patients. The median time for spinal progression and age at onset was 2.2 and 12 y for ERA, and 4 and 16.5 y for SpA, respectively. Activity and damage scores were not significantly different between the groups. Treatment comparison resulted in 91.3% of ERA and 100% SpA being treated, predominantly with NSAIDs in both groups, followed by DMARDs and biologics, with a higher frequency of biologics in SpA. Conclusion: The main differences were the late diagnoses of SpA, and the hip and spine involvement, with higher frequency of biologic treatment in juvenile-onset SpA compared to ERA.

Background: Increased malignancy frequency is well documented in adult-systemic lupus erythematosus (SLE), but with limited reports in childhood-onset SLE (cSLE) series. We explored the frequency of malignancy associated with cSLE, describing clinical and demographic characteristics, disease activity and cumulative damage, by the time of malignancy diagnosis. Method: A retrospective case-notes review, in a nationwide cohort from 27 Pediatric Rheumatology centres, with descriptive biopsy-proven malignancy, disease activity/damage accrual, and immunosuppressive treatment were compiled in each participating centre, using a standard protocol. Results: Of the 1757 cSLE cases in the updated cohort, 12 (0.7%) developed malignancy with median time 10 years after cSLE diagnosis. There were 91% females, median age at cSLE diagnosis 12 years, median age at malignancy diagnosis 23 years. Of all diagnosed malignancies, 11 were single-site, and a single case with concomitant multiple sites; four had haematological (0.22%) and 8 solid malignancy (0.45%). Median (min–max) SLEDAI-2 K scores were 9 (0–38), median (min–max) SLICC/ACR-DI (SDI) score were 1 (1–5) Histopathology defined 1 Hodgkin's lymphoma, 2 non-Hodgkin's lymphoma, 1 acute lymphoblastic leukaemia; 4 gastrointestinal carcinoma, 1 squamous cell carcinoma of the tongue and 1 anal carcinoma; 1 had sigmoid adenocarcinoma and 1 stomach carcinoid; 3 had genital malignancy, being 1 vulvae, 1 cervix and 1 vulvae and cervix carcinomas; 1 had central nervous system oligodendroglioma; and 1 testicle germ cell teratoma. Conclusion: Estimated malignancy frequency of 0.7% was reported during cSLE follow up in a multicentric series. Median disease activity and cumulative damage scores, by the time of malignancy diagnoses, were high; considering that reported in adult series.

Background: Systemic Lupus Erythematosus (SLE) is a heterogeneous multisystem autoimmune disease, with variable severity, autoantibody profile, response to treatment, relapsing course and damage accrual. The age at disease onset may influence disease trajectory and prognosis, with remarkable differences of major organ involvement, disease activity, and prognosis. SLE clinical profile, activity indices, remission, and damage comparison were carried out in childhood-onset (cSLE), adult-onset (aSLE) and late-onset (lSLE) patients from a single-centre series. Methods: A cross-sectional analysis reviewing the clinical profile of SLE cases seen between 2012 and 2022 and classified in 3 age-groups according to disease onset: cSLE (=50 years), was performed. Disease activity status was assessed by PGA (0-3), SLEDAI-2K, SLE-DAS, LLDAS and DORIS criteria, and damage using SDI at the same visit were compared in those 3 age-groups. Results: Four hundred and fifteen patients were included in the analysis: 289 (68%) aSLE, 79 (19%) cSLE, and 47 (11.3%) lSLE. Most common clinical manifestations were articular (75.2%), hematological (70.1%), cutaneous (67.9%), photosensitivity (59.3%), and renal (41.7%). The clinical profile was similar among the subgroups of SLE patients, except for lSLE with lower frequency of nephritis and serositis, lower frequency of autoantibodies and hypocomplementenemia, lower SLEDAI-2K and SLE-DAS scores, and a higher frequency of LLDAS and DORIS remission; and a higher damage scores (SDI). Patients with cSLE had a significantly higher frequency of renal and neurological involvement, and a longer disease duration, but the disease activity, damage scores and remission rates were comparable to adult-onset group. Conclusion: The remarkable differences among the 3-age-groups were higher frequency of renal and neuropsychiatric domains in youngsters and disease activity scores compared to other age-groups. The lSLE group had less nephritis and serositis, lower disease activity and higher damage scores.

Background: Patients with acute heart failure exhibit high rates of early rehospitalization accompanied by significant mortality. Therefore, identifying high-risk patients who are prone to disease exacerbation may enable early therapeutic interventions for improved disease management. Methods: This single-center, prospective observational study was conducted at a Brazilian hospital. Adult patients hospitalized for acute heart failure were enrolled. On the day of hospital discharge, NT-pro-BNP and body weight data were collected, and bedside lung and inferior vena cava ultrasound examinations were performed. The patients were followed up for up to 30 days after discharge. The primary outcome was rehospitalization for acute heart failure. Results: A total of 100 patients were included in the final analysis, of whom 10% were readmitted within 30 days owing to acute heart failure. The number of patients with total B-line scores >3 in the readmitted and non-readmitted groups was 6 and 19, respectively (60% and 21%, respectively; absolute risk difference: 39%; p = 0.014). The mean inferior vena cava collapsibility index was significantly lower in readmitted compared to that in non-readmitted patients (25.5% vs. 39.8%, standard deviation: 15.4% and 18.4%, respectively; p = 0.020). However, mean body weight and mean NT-pro-BNP levels at discharge did not differ between the groups. In a multivariate logistic regression model adjusted for sex, age, discharge body weight, and left ventricular ejection fraction, a total B-lines score >3 had an odds ratio of 4.72 (95% confidence interval (CI): 1.01–22.13; p = 0.049), while the inferior vena cava collapsibility index had an odds ratio of 0.96 (95% CI: 0.91–1.01; p = 0.091). Conclusions: A total B-line score >3 at discharge in patients hospitalized for acute heart failure was associated with 30-day rehospitalization. In contrast, inferior vena cava ultrasound, discharge body weight, and NT-pro-BNP at discharge were not significant predictors of rehospitalization.

Conclusion The main differences were that SpA had late diagnoses and hip spine involvement, with a higher frequency of biologic treatment, than ERA.
