Neurosensory Affectation in Patients Affected by Wolfram Syndrome: Descriptive and Longitudinal Analysis.

Wolfram syndrome (WS) is a rare neurodegenerative disease usually of autosomal recessive origin. There is limited research about sensorineural hearing loss, despite it being a fundamental entity. It is important to broaden the study of this disease and specify a set of tests required for an adequate assessment of patients for efficient monitoring and control. The fundamental objective of this research is to understand WS from a biomedical perspective in order to help in its diagnosis, follow-up, and control. Pure tones audiometry, tympanometry, speech perception, the speech intelligibility index without aid, and testing at high frequencies were among the audiological measurements utilised since they were deemed suitable for standardised follow-up. Mixed linear models were used to examine the effects of age, time, or mean interaction in pure-tone (IPT), the average of high frequencies (HFA), auditory brainstem response (ABR), and brainstem auditory evoked potentials (BAEP). The genetic analysis allowed mutations to be classified into three phenotype-genotype groups, where the phenotype indicated the severity of the hearing loss. Patients with homozygous gene changes had a more severe neurosensory phenotype. The early discovery of sensorineural hearing loss and WS is crucial since it allows intensive follow-up and treatment of the person affected from the start.

Protocolo genético en Atención Primaria para enfermedades raras: el síndrome de Wolfram como prototipo / Genetic protocol in primary care for rare diseases: Wolfram syndrome as a prototype

Las enfermedades raras, pese a su baja frecuencia individual, afectan globalmente al 7% de la población, por lo que el profesional de Atención Primaria (AP) tendrá varios de estos pacientes bajo seguimiento. El 80% de estas enfermedades tienen base genética, lo que hace fundamental un asesoramiento genético adecuado. El seguimiento de pacientes con síndrome de Wolfram (SW) puede servir para diseñar un protocolo susceptible de ser utilizado en el diagnóstico y manejo de otras entidades y ser utilizado por profesionales sanitarios para dar soporte a los pacientes, contando con la participación de profesionales sanitarios e investigadores especializados en el SW, los propios pacientes y su entorno. Se desarrollan los pasos fundamentales de todo procedimiento clínico genético, en el que la AP es clave para dar soporte a estas familias y transmitir de forma comprensible la información sobre los aspectos genéticos.(AU)

Rare diseases, despite their individual low frequency, affect 7% of the population all combined. Consequently, every primary care practitioner (PCP) will have several of these patients under his care. 80% of rare diseases are genetically determined, which makes genetic counseling fundamental in these cases. The follow-up of patients with Wolfram syndrome (WS) can be used to design a protocol to support these patients, with the participation of researchers and healthcare professionals specialized in WS, the patients themselves and their familial environment. This protocol can be suitable for the diagnosis and management of other diseases as well. The main steps of every genetic clinical procedure are developed in this article, emphasizing the role of PCP in supporting patients and their families and in transmitting genetic information in a comprehensible manner.(AU)
