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.

Background: Wolfram syndrome (WFS), also known as DIDMOAD, is a rare monogenic neurodegenerative disorder characterized by four key components: non-autoimmune insulin-dependent diabetes mellitus (DM), optic atrophy, sensorineural hearing loss, and diabetes insipidus. Although it significantly affects quality of life, gonadal dysfunction, particularly hypogonadism, remains underrecognized. Methods: In total, 45 patients (25 men, 20 women) with genetically confirmed WFS from a single tertiary-care center were prospectively followed to assess gonadal function. Men underwent hormonal evaluations, semen analysis, imaging tests, and testicular biopsies. In women, data on age at menarche, menstrual irregularities, and age at menopause were recorded. Hormonal analyses, including anti-Müllerian hormone (AMH) levels, and imaging tests were also conducted. Results: Hypogonadism was identified in 19 men (76.0%), of whom 17 (68.0%) had hypergonadotropic hypogonadism and 2 (8.0%) had hypogonadotropic hypogonadism. Testicular biopsies showed seminiferous tubule damage, Sertoli cell predominance, and reduced Leydig cells. Azoospermia was observed in 12 patients, whereas others presented with oligozoospermia, teratozoospermia, or asthenozoospermia. Most patients exhibited low testosterone levels along with elevated LH and FSH, suggesting primary testicular failure, except for two cases of hypogonadotropic hypogonadism. Correlations between biomarkers, onset age and severity have been analyzed and provide important insights regarding medical treatment. In women, menstrual irregularities were universal, with 20% experiencing premature menopause. Four patients had low AMH levels, with ovarian atrophy in three and a postmenopausal uterus in two, indicating early hypogonadism risk. Conclusions: Gonadal dysfunction is a significant yet overlooked feature of WFS, requiring systematic evaluation during puberty and beyond. Proper management is essential to mitigate metabolic disturbances and psychological impacts, including infertility distress, relationship challenges, and quality of life concerns. Addressing sexual health is crucial as WFS patients live longer and aspire to establish relationships or start families.

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.

Wolfram Syndrome (WS) is a rare disease (RD) with an estimated prevalence of 1/770,000 inhabitants. It is considered a multisystemic, chronic and progressive disease.WS diagnosis implies devastating consequences at physical, educational and emotional levels. WS is also known by the acronym DIDMOAD, derived from the first letters of the main clinical symptoms: Diabetes Insipidus, Diabetes Mellitus, Optic Atrophy, and Deafness. Rare diseases are characterized by their low prevalence and the lack of knowledge on the pathophysiology and treatment of them. Interestingly, around 80% of RD have a genetic basis, and this fact causes doubts and uncertainties in the couples, about the idea of having another child. The existence of a RD in a family, alters significantly the relationships and the quality of life within the family. The present work remarks the huge value of psychosocial aspects in order to pay an adequate attention to these patients, not only taking care of the clinical aspects. The main purpose of this study has been to ascertain the quality of life of Wolfram’s syndrome affected patients, and its impact in the daily life.
