Vestibular Function in Children with Type 1 Diabetes: Videonystagmography Testing.

BACKGROUND

Vestibular system is critical for maintaining balance and learning complex tasks. This study aimed to determine the frequencies, types, and predictors of vestibular dysfunctions (VDs) in children with type 1 diabetes (T1D) using videonystagmography (VNG).

PATIENTS AND METHODS

This study included 65 patients (children with T1D = 40; controls = 25). The patients underwent VNG.

RESULTS

Patients (boys = 15; girls = 25) had a mean age of 14.05 ± 1.82 years and duration of illness of 6.30 ± 2.84 years. The majority had frequent attacks of diabetic ketoacidosis (DKA) (65%) and hypoglycemia (40%). Dizziness was reported in 20%. VNG abnormalities were reported in 70% (n = 28), of them 71.43 and 28.57% had central and peripheral VDs, respectively. Dizziness was associated with peripheral VD. Compared to patients without VDs, those with VDs were older and had earlier age at onset and longer duration of diabetes (>5 years), higher levels of HbA1c (>7%), higher frequencies of DKA and hypoglycemic attacks, comorbid medical conditions, and diabetic complications. Multiple logistic regression analysis showed that presence of VNG abnormalities (VDs) was independently correlated with diabetes duration >5 years (odds ratio [OR] = 4.52 [95% confidence interval [CI] = 3.55-7.04], p = 0.001), HbA1c% levels >7% (OR = 3.42 [95% CI = 2.84-5.75], p = 0.001), and presence of hypoglycemic attacks (OR = 4.65 [95% CI = 2.85-7.55]).

CONCLUSIONS

-VDs are prevalent in children with T1D and correlated with the duration and severity of diabetes and the occurrence of hypoglycemic attacks. Therefore, optimizing glycemic control and prevention and treatment of diabetic complications and comorbidities are important. Multidisciplinary follow-ups are required for early detection and management of diabetic VDs.
