Trial summary

Ataxia telangiectasia (A-T) is a rare devastating human recessive disorder characterized by progressive cerebellar ataxia, immunodeficiency, chromosomal instability, and cancer susceptibility. In addition to that, a high percentage of patients show dystrophy, growth retardation and poor weight gain. Read more about this study

About this study

Official title: Body Composition, Muscle Strength and Hormonal Status in Patients With Ataxia Telangiectasia Compared to Healthy Controls

Ataxia telangiectasia (A-T) is a rare devastating human recessive disorder characterized by progressive cerebellar ataxia, immunodeficiency, chromosomal instability, and cancer susceptibility. In addition to that, a high percentage of patients show dystrophy, growth retardation and poor weight gain. Nevertheless, there are only a few studies assessing this problem. Aim of the present proposal is to investigate the exact body composition, manual muscle strength and hormonal status in patients with A-T compared to healthy controls matched for gender and age. A pelvic sonography in females was performed in order to evaluate the sexual maturity of their inner genitalia. Tanner score was determined to define the physical development. Every subject received a nutritional diary to review its calorie intake and the quality of diet. The investigators expect that the A-T cohort shows an altered body composition, impaired muscle strength, changed hormonal status concerning the sexual hormones and a delayed physical development compared to healthy controls.

Read the detailed description

Ataxia telangiectasia (A-T) is a devastating human recessive disorder characterized by progressive cerebellar ataxia, immunodeficiency, chromosomal instability, and cancer susceptibility. In addition to that, a high percentage of patients show dystrophy, growth retardation and poor weight gain. There are only a few studies assessing this problem and the exact variations concerning body composition, muscle strength and hormonal status are widely unknown.

Major factors may be responsible for altered body composition:

  1. Immunodeficiency and chronic disease are important influences on growth and physical development. The constantly catabolic situation of A-T patients has a major impact on dystrophy.
  2. Due to the progressive cerebellar ataxia most of the patients are bound to wheelchair so that their muscle mass is decreased
  3. Impaired muscle strength is related to apraxia, dystonia, contractures and dyskinesia.
  4. Low levels of growth hormones (GH). Extracerebellar MRI - lesions in A-T go along with deficiency of the GH axis thus causing nanism.
  5. Delayed puberty and physical development suggest an abnormal metabolism in muscle cells
  6. There are autopsy reports informing about reduced mass of the adrenal cortex that may be reflected in a lower hormone release of steroid hormones.

The aim of the proposal is to explore the exact body composition, the manual muscle strength, the hormonal status in patients with A-T compared to healthy subjects matched for sex and age. One study visit is performed in all A-T patients and healthy subjects:

  • To evaluate weight and length of all subjects
  • To analyze the exact structure of single body compartments such as the lean mass, the water compartment or the fat compartment using bioelectrical impedance analysis
  • To determine the subcutaneous fat fold thickness using calipometry
  • To investigate the nourishment habits and diet detected by nutritional diary
  • To analyze the manual muscle strength with a hand dynamometer
  • To determine the physical development in the A-T cohort by Tanner scores
  • To evaluate stage of sexual development and puberty in female A-T patients by ultrasonic of the inner genitalia
  • To get a detailed hormonal status including thyroid-stimulating hormone (TSH), luteinizing hormone (LH), follicle stimulating hormone (FSH), GH, cortisol, DHEAS, estradiol, testosterone, progesterone, insulin like growth factor-binding protein 3 (IGF-BP3), etc in serum blood

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • bioelectrical impedance analysisProcedure or surgery

    electrophysical measurement that allows to determine the exact composition of single body compartments by producing a magnetic field and detecting the potential difference through the body

  • blood drawProcedure or surgery

    blood samples are taken at 8 am in order to pay attention to the circadian rhythmicity to get a detailed hormonal status

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02345200, which also lists 8 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jan 2015.
