  abstract  = {Background Fabry disease is characterized by a progressive deposition of sphingolipids in different organ systems, whereby cardiac involvement leads to death. We hypothesize that lysosomal storage of sphingolipids in the heart as occurring in Fabry disease does not reflect in higher cardiac lipid concentrations detectable by \(^1\)H magnetic resonance spectroscopy (MRS) at 3 Tesla. Methods Myocardial lipid content was quantified in vivo by \(^1\)H-MRS in 30 patients (12 male, 18 female; 18 patients treated with enzyme replacement therapy) with genetically proven Fabry disease and in 30 healthy controls. The study protocol combined \(^1\)H-MRS with cardiac cine imaging and LGE MRI in a single examination. Results Myocardial lipid content was not significantly elevated in Fabry disease (p = 0.225). Left ventricular (LV) mass was significantly higher in patients suffering from Fabry disease compared to controls (p = 0.019). Comparison of patients without signs of myocardial fibrosis in MRI (LGE negative; n = 12) to patients with signs of fibrosis (LGE positive; n = 18) revealed similar myocardial lipid content in both groups (p > 0.05), while the latter showed a trend towards elevated LV mass (p = 0.076). Conclusions This study demonstrates the potential of lipid metabolic investigation embedded in a comprehensive examination of cardiac morphology and function in Fabry disease. There was no evidence that lysosomal storage of sphingolipids influences cardiac lipid content as measured by \(^1\)H-MRS. Finally, the authors share the opinion that a comprehensive cardiac examination including three subsections (LGE; \(^1\)H-MRS; T\(_1\) mapping), could hold the highest potential for the final assessment of early and late myocardial changes in Fabry disease.},

  abstract  = {Background In individuals suffering from a rare disease the diagnostic process and the confirmation of a final diagnosis often extends over many years. Factors contributing to delayed diagnosis include health care professionals' limited knowledge of rare diseases and frequent (co-)occurrence of mental disorders that may complicate and delay the diagnostic process. The ZSE-DUO study aims to assess the benefits of a combination of a physician focusing on somatic aspects with a mental health expert working side by side as a tandem in the diagnostic process. Study design This multi-center, prospective controlled study has a two-phase cohort design. Methods Two cohorts of 682 patients each are sequentially recruited from 11 university-based German Centers for Rare Diseases (CRD): the standard care cohort (control, somatic expertise only) and the innovative care cohort (experimental, combined somatic and mental health expertise). Individuals aged 12 years and older presenting with symptoms and signs which are not explained by current diagnoses will be included. Data will be collected prior to the first visit to the CRD's outpatient clinic (T0), at the first visit (T1) and 12 months thereafter (T2). Outcomes Primary outcome is the percentage of patients with one or more confirmed diagnoses covering the symptomatic spectrum presented. Sample size is calculated to detect a 10 percent increase from 30\% in standard care to 40\% in the innovative dual expert cohort. Secondary outcomes are (a) time to diagnosis/diagnoses explaining the symptomatology; (b) proportion of patients successfully referred from CRD to standard care; (c) costs of diagnosis including incremental cost effectiveness ratios; (d) predictive value of screening instruments administered at T0 to identify patients with mental disorders; (e) patients' quality of life and evaluation of care; and f) physicians' satisfaction with the innovative care approach. Conclusions This is the first multi-center study to investigate the effects of a mental health specialist working in tandem with a somatic expert physician in CRDs. If this innovative approach proves successful, it will be made available on a larger scale nationally and promoted internationally. In the best case, ZSE-DUO can significantly shorten the time to diagnosis for a suspected rare disease.},

  abstract  = {Seltene Erkrankungen (SE) werden durch die im deutschen Gesundheitssystem verwendete Diagnosenklassifikation ICD-10-GM (International Statistical Classification of Diseases and Related Health problems, 10th Revision, German Modification) nur zu einem kleinen Teil eindeutig erfasst. Daher sind Aussagen zur H{\"a}ufigkeit von SE sowie zum speziellen Versorgungs- und Finanzierungsbedarf nicht m{\"o}glich, was zu einer l{\"u}ckenhaften Datenlage als Entscheidungsgrundlage f{\"u}r Krankenkassen, Leistungserbringer und Gesundheitspolitik f{\"u}hrt. Das Fehlen exakter Informationen behindert auch die wissenschaftliche Arbeit. Daher wird deutschlandweit ab 2023 die Verwendung der Alpha-ID-SE-Datei und der ORPHAcodes f{\"u}r die spezifische Erfassung von SE bei station{\"a}ren F{\"a}llen verpflichtend. Die Alpha-ID-SE-Datei verkn{\"u}pft die ICD-10-GM-Kodes mit den international anerkannten ORPHAcodes f{\"u}r die Diagnose von SE. Kommerzielle Anbieter stellen zunehmend die ben{\"o}tigten IT-Tools zur Kodierung von SE zur Verf{\"u}gung. An mehreren Universit{\"a}tskliniken mit Zentren f{\"u}r SE wurden L{\"o}sungen etabliert, die eine vollst{\"a}ndige Kodierung gew{\"a}hrleisten sollen. Hierzu geh{\"o}ren finanzielle Anreize f{\"u}r die kodierenden Bereiche, konkrete Nachfragen nach dem Vorliegen einer SE beim Kodiervorgang und eine semiautomatische Kodierung bei Patient*innen, die schon einmal mit einer SE an der Einrichtung betreut worden waren. Eine Kombination der verschiedenen Ans{\"a}tze verspricht die h{\"o}chste Wahrscheinlichkeit einer vollst{\"a}ndigen Kodierung. F{\"u}r ein umf{\"a}ngliches Bild der SE im Gesundheitssystem und um dem speziellen Versorgungs- und Finanzierungsbedarf besser Rechnung tragen zu k{\"o}nnen, w{\"a}re auch im ambulanten Bereich eine m{\"o}glichst spezifische und eindeutige Kodierung w{\"u}nschenswert. F{\"u}r komplexe SE und bisher undiagnostizierte Patient*innen wird zus{\"a}tzlich eine strukturierte Erfassung des Ph{\"a}notyps ben{\"o}tigt.},
