      <MainHeadline>Text</MainHeadline><Pgraph><Mark1>Introduction: </Mark1>Early and consequent treatment of newly diagnosed rheumatic diseases in children improves disease course and prognosis. Treat-to-Target (T2T) strategies facilitate the achievement of early disease inactivity. The Society of Pediatric Rheumatology published recommendations for JIA, cSLE, and JDM. The ProKind-Rheuma Study evaluates implementation and short-term outcomes, including disease inactivity, quality of life, daily functioning, and therapy satisfaction.</Pgraph><Pgraph><Mark1>Methods: </Mark1>From January 2020 to April 2023, children newly diagnosed with JIA, cSLE, or JDM were enrolled at 23 pediatric rheumatology centers in the ProKind-Rheuma observational study. Participants were monitored for disease activity, daily functioning, and quality of life using disease-specific scores and validated questionnaires. Twelve-month follow-up data were available for 383 JIA, 31 cSLE, and 18 JDM patients.</Pgraph><Pgraph><Mark1>Results: </Mark1>At 12 months, mean disease activity scores decreased significantly: cJADAS10 -9.6, SLEDAI-2k -7.6, and JDM-DAS -7.6. Inactive disease was achieved in 59.8&#37; of JIA (cJADAS10 &#8804; 1.1 for oligoarthritis, &#8804;2.5 for polyarthritis), 22,6&#37; of cSLE (SLEDAI-2k &#61; 0 and PhGA &#60; 2), and 33.3&#37; of JDM (3 out of 4: CK normal, CMAS &#8805; 48, MMT-8 &#8805; 78, PhGA &#60; 1) patients.</Pgraph><Pgraph>Overall, disease-related quality of life improved remarkably (mean PedsQL 4.0 scores 82&#8211;86 at 12 months). However, disease-specific quality of life remained lower for JDM (mean PedsQL 3.0: 60.5 &#177; 21.3) and JIA (72.1 &#177; 23.1) regarding treatment burden, and for cSLE (75.2 &#177; 26.8) regarding worries.</Pgraph><Pgraph>JDM patients had the largest impairment in daily functioning both at baseline and follow-up (QHAQ-Scores: 0.9 &#177; 1.0 and 0.4 &#177; 0.5, respectively). Fatigue was a persistent issue especially for cSLE patients.</Pgraph><Pgraph>Medication side effects were reported in 31&#37; (JIA), 27&#37; (cSLE), and 43&#37; (JDM) of patients, causing treatment discontinuation in about 30&#37; of cases. Over 90&#37; of patients took medication regularly.
