Subjects

Abstract

Body weight changes occur frequently during advanced stages of Spinocerebellar Ataxia type 2 (SCA2), nevertheless limited information exists on biomarkers of nutritional status of these patients. To assess changes in surrogate nutritional markers of SCA2 patients; to explore their associations with expanded CAG repeats and disease severity. One-hundred-thirteen SCA2 patients and 50 healthy controls underwent a comprehensive anthropometrical and biochemical assessment protocol of the nutritional status. Neurological and genotype assessments were also performed. A decrease in weight, body mass index (BMI), cutaneous skinfold thickness, fat mass, arm muscle circumference, calf circumference and skeletal muscle mass was observed in SCA2 patients compared to the controls. The total/HDL cholesterol ratio was significantly reduced in patients. BMI was correlated with the age at onset. Overall, anthropometric measures were correlated with clinical markers of disease severity and were more evident in severe and moderate cases. Using anthropometric measures in the assessment of the nutritional status of SCA2 patients might provide hints about pathophysiological mechanisms that underlie metabolic abnormalities in SCA2. Anthropometric are close related with disease severity and progression, and trigger preventive therapies aimed to ameliorate weight loss and wasting in these patients. [ABSTRACT FROM AUTHOR]

24. Involvement of the Auditory Pathway in Spinocerebellar Ataxia Type 7.

Abstract

Background: Spinocerebellar ataxia type 7 (SCA7) is an autosomal dominant disorder caused by a mutation in the ATXN7 gene. The involvement of the brainstem auditory pathway in pathogenesis of this disease has not been systematically assessed. Aim: To determine involvement of the brainstem auditory pathway in SCA7 patients and its relationship to clinical features of the disease. Methods: In this case-control study, brainstem auditory-evoked potentials (BAEPs) were assessed in 12 SCA7 patients with clinical and molecular diagnosis, compared to 2 control groups of 16 SCA2 patients and 16 healthy controls. Results: SCA7 patients exhibited significant prolongation of I-wave and III-wave latencies, whereas SCA2 patients showed increased latencies for III and V waves and I–III interpeak interval. SCA7 patients with larger I-wave latencies exhibited larger CAG repeats, earlier onset age, and higher SARA scores, but in SCA2 cases, these were not observed. Conclusions: BAEP tests revealed functional involvement of the auditory pathway in SCA7 (mainly at) peripheral portions, which gave new insights into the disease physiopathology different from SCA2 and may unravel distinct pathoanatomical effects of polyQ expansions in the central nervous system. Significance: These findings offer important insights into the distinctive disease mechanisms in SCA7 and SCA2, which could be useful for differential diagnosis and designing specific precision medicine approaches for both conditions.

Abstract

The prevalence estimations of hereditary ataxias are biased since most epidemiological studies are confined to isolated geographical regions and few nationwide studies are available. The study aims to assess the prevalence, distribution, and neurological features of the Cuban population with hereditary ataxias. A nationwide epidemiological study of hereditary ataxias was conducted in Cuba between March 2017 and June 2018. Patients were scheduled at the Cuban ataxia research center, various hospitals, or at their homes. Demographic and clinical variables were obtained through standardized questionnaires and validated clinical tools. Overall, 1001 patients were diagnosed with hereditary ataxias for a nationwide prevalence of 8.91 cases/100.000 inhabitants. Spinocerebellar ataxia type 2 (SCA2) was the commonest subtype, with highest prevalences at Holguín province (47.86/100.000), and a broad dissemination in the whole country. Most of neurological features were common between all SCA cohorts, but the frequencies of some of them varied between distinct subtypes. Within the SCA2 cohort, significant influences of long mutation size and higher disease duration over the muscle atrophy and oculomotor disorders were observed. Besides, higher disease durations were associated with resting tremor and dysphagia, whereas shorter disease durations were associated with hyperreflexia. The spreading of SCA2 to whole country and the documented raising of its prevalence set the rationales for higher-scope medical care and research strategies, supported in collaborative research networks. The wide epidemiological, clinical, and genetic characterization of this founder SCA2 population identifies this homogeneous cohort as an attractive source for the development of future clinical-genetic and therapeutic researches.
