Objective Juvenile dermatomyositis (DM) is a rare and severe autoimmune condition characterized by rash and proximal muscle weakness. While some patients respond to standard treatment, others do not. This study was carried out to investigate whether histopathologic findings and myositis‐specific autoantibodies (MSAs) have prognostic significance in juvenile DM. Methods Muscle biopsy samples (n = 101) from patients in the UK Juvenile Dermatomyositis Cohort and Biomarker Study were stained, analyzed, and scored for severity of histopathologic features. In addition, autoantibodies were measured in the serum or plasma of patients (n = 90) and longitudinal clinical data were collected (median duration of follow‐up 4.9 years). Long‐term treatment status (on or off medication over time) was modeled using generalized estimating equations. Results Muscle biopsy scores differed according to MSA subgroup. When the effects of MSA subgroup were accounted for, increased severity of muscle histopathologic features was predictive of an increased risk of remaining on treatment over time: for the global pathology score (histopathologist's visual analog scale [hVAS] score), 1.48‐fold higher odds (95% confidence interval [95% CI] 1.12–1.96; P = 0.0058), and for the total biopsy score (determined with the standardized score tool), 1.10‐fold higher odds (95% CI 1.01–1.21; P = 0.038). A protective effect was identified in patients with anti–Mi‐2 autoantibodies, in whom the odds of remaining on treatment were 7.06‐fold lower (95% CI 1.41–35.36; P = 0.018) despite muscle biopsy scores indicating more severe disease. In patients with anti–nuclear matrix protein 2 autoantibodies, anti–transcription intermediary factor 1γ autoantibodies, or no detectable autoantibody, increased histopathologic severity alone, without adjustment for the effect of MSA subtype, was predictive of the risk of remaining on treatment: for the hVAS global pathology score, 1.61‐fold higher odds (95% CI 1.16–2.22; P = 0.004), and for the total biopsy score, 1.13‐fold higher odds (95% CI 1.03–1.24; P = 0.013). Conclusion Histopathologic severity, in combination with MSA subtype, is predictive of the risk of remaining on treatment in patients with juvenile DM and may be useful for discussing probable treatment length with parents and patients. Understanding these associations may identify patients at greater risk of severe disease.

Objective The Pediatric Rheumatology International Trials Organisation (PRINTO) recently published criteria for classification of patients with juvenile dermatomyositis (DM) as having clinically inactive disease. The criteria require that at least 3 of 4 conditions be met, i.e., creatine kinase level ≤150 units/liter, Childhood Myositis Assessment Scale score ≥48, Manual Muscle Testing in 8 muscles score ≥78, and physician's global assessment of overall disease activity (PGA) ≤0.2. The present study was undertaken to test these criteria in a UK cohort of patients with juvenile DM. Methods We assessed 1,114 patient visits for the 4 items in the PRINTO criteria for clinically inactive disease. Each visit was analyzed to determine whether skin disease was present. The Disease Activity Score (DAS) for juvenile DM was determined in 59 patients. Results At 307 of the 1,114 visits, clinically inactive disease was achieved based on the 3 muscle criteria (but with a PGA of >0.2); rash was present at 65.8% of these visits and nailfold capillary abnormalities at 35.2%. When PGA ≤0.2 was one of the 3 criteria that were met, the frequency of skin signs was significantly lower (rash in 23.1% and nailfold capillary abnormalities in 8.7%). If PGA was considered an essential criterion for clinically inactive disease (P‐CID), patients with active skin disease were less likely to be categorized as having clinically inactive disease (a median DAS skin score of 0 [of a possible maximum of 9] in visits where the PGA was ≤0.2, versus a median DAS skin score of 4 in patients meeting the 3 muscle criteria [with a PGA of >0.2]; P < 0.001). Use of the P‐CID led to improvements in the positive predictive value and the positive likelihood ratio (85.4% and 11.0, respectively, compared to 72.9% and 5.1 with the current criteria). Conclusion There was a high frequency of skin disease among patients with juvenile DM who did not meet the PGA criterion for inactive disease but met the other 3 criteria. Incorporating PGA as an essential criterion for clinically inactive disease helps prevent the misclassification of patients with active skin disease.

Background: Pharmacists in Australia are accessible health care professionals, and their provision of clinical pharmacy interventions in a range of areas has been proven to improve patient outcomes. Individual clinical pharmacy interventions in the area of asthma management have been very successful. An understanding of the nature of these interventions will inform future pharmacy services. What we do not know is when pharmacists provide a complex asthma service, what elements of that service (interventions) they choose to deliver. Objective: To explore the scope and frequency of asthma-related clinical interventions provided by pharmacists to patients in an evidence-based complex asthma service. Methods: Pharmacists from 4 states/territories of Australia were trained in asthma management. People with asthma had 3 or 4 visits to the pharmacy. Guided by a structured patient file, the pharmacist assessed the patient´s asthma and management and provided interventions where and when considered appropriate, based on their clinical decision making skills. The interventions were recorded in a checklist in the patient file. They were then analysed descriptively and thematically. Results: Pharmacists provided 22,909 clinical pharmacy interventions over the service to 570 patients (398 of whom completed the service). The most frequently delivered interventions were in the themes "Education on asthma", "Addressing trigger factors", "Medications - safe and effective use" and "Explore patient perspectives". The patients had a high and ongoing need for interventions. Pharmacists selected interventions based on their assessment of perceived need then revisited and reinforced these interventions. Conclusion: Pharmacists identified a number of areas in which patients required interventions to assist with their asthma management. Many of these were perceived to require continuing reinforcement over the duration of the service. Pharmacists were able to use their clinical judgement to assess patients and provide clinical pharmacy interventions across a range of asthma management needs. Antecedentes: Los farmacéuticos en Australia son profesionales de la salud accesibles y su prestación de intervenciones de farmacia clínica ha demostrado mejorar los resultados de salud de los pacientes en un conjunto de áreas. Las intervenciones de farmacia clínica en asma han demostrado ser de gran éxito. La comprensión de la naturaleza de estas intervenciones informará para los futuros servicios farmacéuticos. Lo que no sabemos es, cuando los farmacéuticos proporcionan un servicio complejo de asma, que elementos del servicio (intervenciones) eligen realizar. Objetivo: Explorar el ámbito y la frecuencia de las intervenciones clínicas en asma proporcionadas por farmacéuticos a pacientes en un servicio complejo de asma basado en la evidencia. Métodos: Se entrenó en el manejo del asma a farmacéuticos de 4 estados/territorios de Australia. La gente con asma visitaba 3 o 4 veces la farmacia. Guiado por un registro estructurado del paciente, el farmacéutico evaluaba el asma y el manejo y las intervenciones realizadas cuando y donde consideraba necesario, basándose en sus habilidades de toma de decisión clínica. Se registraban las intervenciones en un check-list en la historia del paciente. Se analizaron descriptiva y temáticamente. Resultados: Los farmacéuticos proporcionaron 22.909 intervenciones de farmacia clínica en el servicio a 570 pacientes (de los que 398 completaron el servicio). Las intervenciones más frecuentemente realizadas estaban en los temas "Educación sobre asma", "Manejando factores desencadenantes", "Medicación - uso seguro y efectivo" y "Explorar las perspectivas del paciente". Los pacientes presentaban una gran y continuada necesidad de intervenciones. Los farmacéuticos seleccionaron las intervenciones basándose en su juicio de la necesidad percibida y después revisaron y reforzaron esas intervenciones. Conclusión: Los farmacéutico identificaron varias áreas en las que los pacientes necesitaban intervenciones para ayudarles en su manejo del asma. Muchas de estas requirieron refuerzo continuo durante la prestación del servicio. Los farmacéuticos fueron capaces de utilizar su juicio clínico para evaluar pacientes y proporcionar intervenciones de farmacia clínica en un amplio abanico de necesidades de manejo del asma.
