Abstract
Background Wolfram syndrome (WFS) is a rare, monogenic neurodegenerative syndrome characterised by insulin requiring non-autoimmune diabetes mellitus (DM) and optic atrophy which are usually the earliest and commonest manifestations. However, there are other features which are under-recognized, adding to morbidity and premature mortality in these patients. Methods Five patients (three males, two females) with genetically confirmed WFS at a single tertiary care centre were prospectively followed up. Their symptomatology, clinical profile, genetic analysis and radiology were analyzed. Multidisciplinary approach was used for comprehensive clinical care of this cohort. Patients with primary gonadal failure were subjected to biopsy and immunohistochemistry (IHC) for wolframin was performed. Results DM was the earliest presenting manifestation at 6.2 ± 1.3 years followed by optic atrophy at 10.4 ± 2.3 years, diabetes insipidus at 12 ± 2.1 years and deafness at 12.8 ± 2.1 years. All patients were autoantibody negative with low C-peptide(n = 2). Testicular biopsy revealed partly hyalinised seminiferous tubules and prominence of Leydig cells. IHC confirmed the presence of mutated wolframin, which was not significantly different from normal testis specimen on protein quantification. Conclusions WFS requires a multidisciplinary approach with special emphasis on early diagnosis and management of other endocrine and non-endocrine features so as to improve long-term outcomes. Gonadal functions need periodic assessment, especially in adult males.This publication has 33 references indexed in Scilit:
