Development and preliminary validation of a paediatric-targeted MRI scoring system for the assessment of disease activity and damage in juvenile idiopathic arthritis.
Objectives To develop and validate a paediatric-targeted
MRI scoring system for the assessment of disease
activity and damage in juvenile idiopathic arthritis (JIA).
To compare the paediatric MRI score with the adultdesigned. Outcome Measures in Rheumatology Clinical
Trials\u2014Rheumatoid Arthritis MRI Score (RAMRIS),
whose suitability for assessing growing joints was tested.
Methods In 66 patients with JIA the clinically more
affected wrist was studied. Thirty-nine patients had
a 1-year MRI follow-up. Two readers independently
assigned the paediatric score and the RAMRIS to all
studies. Validation procedures included analysis of
reliability, construct validity and responsiveness to
change. A reduced version of the bone erosion score was
also developed and tested.
Results The paediatric score showed an excellent
reproducibility (interclass correlation coeffi cient >0.9).
The interobserver agreement of RAMRIS was moderate
for bone erosions and excellent for bone marrow oedema
(BMO). The paediatric score and RAMRIS provided similar
results for construct validity. The responsiveness to
change of the paediatric score was moderate for synovitis
and bone erosion, and poor for BMO and did not improve
when RAMRIS was applied. The reduced version of the
bone erosion was valuable for the assessment of joint
damage, and provided time-saving advantages.
Conclusion The results demonstrate that the paediatric
MRI score is a reliable and valid method for assessing
disease activity and damage in JIA. Unexpectedly,
the RAMRIS provides acceptable suitability for use in
the paediatric age group. Further work, especially in a
longitudinal setting, is required before defi ning the most
suitable MRI scale for assessing growing joints
Coronavirus disease 2019: features of comprehensive cardiac and pulmonary rehabilitation
The expert consensus of the Russian communities discusses the issues of comprehensive medical rehabilitation of patients with coronavirus disease 2019 (COVID-19). COVID-19 is a contagious infectious disease that can cause pulmonary, cardiac, motor, metabolic, neurocognitive and mental disorders, that is, multiple organ dysfunction. COVID-19 survivors, especially after a severe clinical course, face serious psychological and physical problems, posttraumatic stress, cognitive dysfunction, nutritional deficiencies and exacerbation of concomitant chronic diseases. Some patients, regardless of the COVID-19 severity, have a long clinical course of the disease (“chronic-COVID”, “long COVID”). There is evidence of post-acute COVID-19 syndrome. In this regard, patients after COVID-19 will need rehabilitation measures. The expert consensus of the Russian communities presents general principles, stages and aspects of medical rehabilitation after COVID-19, indications and contraindications for rehabilitation interventions. The paper includes recommendations on comprehensive cardiac and pulmonary rehabilitation, as well as specifics of rehabilitation care for different COVID-19 courses within the national three-stage rehabilitation system
Performance of Birmingham Vasculitis Activity Score and disease extent index in childhood vasculitides.
OBJECTIVES: To evaluate the performance of the Birmingham Vasculitis Activity Score (BVAS) v3 and the Disease Extent Index (DEI) for the assessment of disease activity in 4 primary childhood (c-) systemic vasculitides. METHODS: Patients fulfilling the EULAR/PRINTO/PRES (Ankara) c-vasculitis classification criteria for Henoch-Schönlein purpura (HSP), childhood (c) polyarteritis nodosa (c-PAN), c-Wegener's granulomatosis (c-WG) and c-Takayasu arteritis (c-TA) with disease duration at the time of diagnosis ≤3 months were extracted from the PRINTO database. The performance of the BVAS and DEI were examined by assessing convergent validity, the pattern of disease involvement, and responsiveness. We also evaluated alternative unweighted scoring methods for both tools. RESULTS: The analysis set included 796 patients with 669 HSP, 80 c-PAN, 25 c-WG and 22 c-TA. The median age at diagnosis was 6.9 years (6.6-12) and median delay in making the diagnosis from the onset of signs/symptoms was 0.01 (0.003-0.027) years. A strong correlation was found between the BVAS and DEI (rs=0.78) while correlation with the physician global assessment was moderate (rs=0.48) with BVAS and poor with DEI (rs=0.25). Both the BVAS and DEI sub-scores and total scores were able to descrive the disease involvement in the 4 childhood vasculitides. Responsiveness was large (>1.5) for both tools. The performance characteristics of the BVAS and DEI with the unweighted methods were comparable. CONCLUSIONS: This study demonstrates that both the BVAS and DEI are valid tools for the assessment of the level of disease activity in a large cohort of childhood acute and chronic vasculitides
