Study Determining the Frequency of Duchenne Muscular Dystrophy and Late-onset Pompe Disease

N/ACompletedNCT04120168

Turkish Society of Pediatric Gastroenterology, Hepatology and Nutrition590 enrolled

Overview

This is a multicenter prospective non-drug screening study. The working period is 12 months. There is no research product to be followed or used in the study. Demographic data, medical and family histories of the patients included in the study will be collected at the first admission. The following laboratory values of the patients will be collected: * Alanine Transaminase (ALT) * Aspartate Transaminase (AST) * Gamma Glutamyl Transferase (GGT) * Creatine Phosphokinase (CPK) * In addition, physical examination information and Abdominal USG and Liver Biopsy Results, if any, will be collected. Following the above scans, enzyme analysis for late-onset Pompe disease in boys and girls and adolescents with high CPK levels and molecular genetic tests for Duchenne muscular dystrophy in boys and adolescents with high CPK levels will be performed.

OBSERVATIONAL

Enrollment

590

Conditions

Duchenne Muscular Dystrophy Pompe Disease (Late-onset)

Interventions

Laboratory Tests

* Acid Alpha IgGlucosidase alpha enzyme test for Late Onset Pompe Disease and gene sequencing test from the same sample in samples with low enzyme activity * Genetic Analysis for DMD (only in boys): Detection of dystrophin gene for duplication and deletion with MLPA (Multiplex-ligation dependent probe amplification) and re-screening for other mutations by gene sequencing in patients without MLPA deletion / duplication.

Outcomes

Primary Outcomes

Frequency of Duchenne muscular dystrophin in boys and adolescents

The endpoints of the study were to determine the frequency of Duchenne muscular dystrophin in boys and adolescents with unexplained transaminase elevation for at least 3 months and in late onset Pompe disease in girls and boys and to determine the demographic and clinical characteristics of these patients.

Time frame: 1 year
