The Pathogenic TSH β-Subunit Variant C105Vfs114X Causes a Modified Signaling Profile at TSHR

1) Background: Central congenital hypothyroidism (CCH) is a rare endocrine disorder that can be caused by mutations in the β-subunit of thyrotropin (TSHB). The TSHB mutation C105Vfs114X leads to isolated thyroid-stimulating-hormone-(TSH)-deficiency and results in a severe phenotype. The aim of this study was to gain more insight into the underlying molecular mechanism and the functional effects of this mutation based on two assumptions: a) the three-dimensional (3D) structure of TSH should be modified with the C105V substitution, and/or b) whether the C-terminal modifications lead to signaling differences. 2) Methods: wild-type (WT) and different mutants of hTSH were generated in human embryonic kidney 293 cells (HEK293 cells) and TSH preparations were used to stimulate thyrotropin receptor (TSHR) stably transfected into follicular thyroid cancer cells (FTC133-TSHR cells) and transiently transfected into HEK293 cells. Functional characterization was performed by determination of Gs, mitogen activated protein kinase (MAPK) and Gq/11 activation. 3) Results: The patient mutation C105Vfs114X and further designed TSH mutants diminished cyclic adenosine monophosphate (cAMP) signaling activity. Surprisingly, MAPK signaling for all mutants was comparable to WT, while none of the mutants induced PLC activation. 4) Conclusion: We characterized the patient mutation C105Vfs114X concerning different signaling pathways. We identified a strong decrease of cAMP signaling induction and speculate that this could, in combination with diverse signaling regarding the other pathways, accounting for the patient's severe phenotype

Ein strukturierter Versorgungspfad von der Pädiatrie in die Erwachsenenmedizin für Jugendliche und junge Erwachsene mit einer seltenen Erkrankung

Die erfolgreiche Organisation und Umsetzung des Übergangs von Jugendlichen und jungen Erwachsenen mit einer chronischen seltenen Erkrankung aus der Pädiatrie in eine Versorgungsform (Transition) und Versorgungsstruktur (Transfer) der Erwachsenenmedizin ist eine wichtige Aufgabe im dezentral aufgebauten deutschen Gesundheitssystem. Ein mittlerweile in der Praxis erprobtes Programm stellt der strukturierte Versorgungspfad des vom Innovationsfonds des gemeinsamen Bundesausschuss (G‑BA) geförderten Konsortiums TRANSLATE-NAMSE dar (Förderkennzeichen 01NVF16024 TRANSLATE-NAMSE). Grundlage des Übergangs in diesem Programm ist der qualitätsgesicherte Informations- und Kompetenztransfer vom pädiatrischen Behandlungsteam zum adoleszenten Patienten, sowie zur neuen Versorgungseinrichtung. Basierend auf einer strukturierten Epikrise und Erhebung des individuellen Beratungsbedarfs erfolgt, ab dem Alter von 16 Jahren, die strukturierte Transitionsschulung des Patienten durch den Pädiater. Nach erfolgreich absolvierten Transfersprechstunden, gemeinsam mit Vertretern der bisherigen pädiatrischen und der zukünftigen erwachsenenmedizinischen Versorgungseinrichtungen, mündet der Prozess in die Übergabe aller notwendigen medizinischen Unterlagen an den Patienten und den Weiterbehandler sowie den Wechsel des Patienten in die neue Versorgungseinrichtung. Eine abschließende Evaluation des Projekts ist für Herbst 2020 geplant.The successful organization and management of the transition and transfer of adolescents and young adults with a chronic rare disease from pediatric to adult care is an important but complex task in the decentralized German healthcare system. The structured transition pathway of the consortium TRANSLATE-NAMSE, funded by the innovation fund of the Federal Joint Committee (G-BA, funding number 01NVF16024 TRANSLATE-NAMSE) is a program that has meanwhile been tested in practice. The main principle of the transition in this program is the quality-assured transfer of information from the pediatric treatment team to the adolescent patient as well as to the healthcare provider(s) of the adult care facility. Based on a structured assessment and documentation of the individual need for information, the transition training is carried out by the pediatric treatment team for adolescent patients aged 16 years and older. In addition, transfer clinics, with the representatives of the previous pediatric and the future adult healthcare providers and the transfer of all necessary medical documentation to the patient and to the new health care provider are part of the program. A final evaluation of the project is expected in late 2020

Transition for adolescents with a rare disease

$\bf Purpose$ The transition process from paediatric/adolescent to adult medical care settings is of utmost importance for the future health of adolescents with chronic diseases and poses even more difficulties in the context of rare diseases (RDs). Paediatric care teams are challenged to deliver adolescent-appropriate information and structures. Here we present a structured transition pathway which is patient-focused and adoptable for different RDs. $\bf Methods$ The transition pathway for adolescents 16 years and older was developed and implemented as part of a multi-centre study in 10 university hospitals in Germany. Key elements of the pathway included: assessment of patients' disease-related knowledge and needs, training/educational and counselling sessions, a structured epicrisis and a transfer appointment jointly with the paediatric and adult specialist. Specific care coordinators from the participating university hospitals were in charge of organization and coordination of the transition process. $\bf Results$ Of a total of 292 patients, 286 completed the pathway. Deficits in disease-specific knowledge were present in more than 90% of participants. A need for genetic or socio-legal counselling was indicated by > 60%. A mean of 2.1 training sessions per patient were provided over a period of almost 1 year, followed by the transfer to adult care in 267 cases. Twelve patients remained in paediatric care as no adult health care specialist could be identified. Targeted training and counselling resulted in improved disease-specific knowledge and contributed to empowering of patients. $\bf Conclusion$ The described transition pathway succeeds to improve health literacy in adolescents with RDs and can be implemented by paediatric care teams in any RD specialty. Patient empowerment was mainly achieved by individualized training and counselling
