Protocol - Disorders of Respiratory Control with Inherent Autonomic Dysregulation

Add to My Toolkit
Description

The American Thoracic Society (ATS) policy statement regarding Congenital Central Hypoventilation Syndrome (CCHS) is a comprehensive guide for diagnosing an individual with CCHS by evaluating their phenotype and determining their paired-like homeobox gene (PHOX2B) genotype. Evaluation via the ATS statement involves completion of (1) the Autonomic Nervous System Questionnaire (ANSQ), (2) stepwise PHOX2B genetic testing, and (3) physiologic and other clinical testing.

  • The ANSQ is a self-administered questionnaire including 46 questions with the purpose of measuring Autonomic Nervous System Dysregulation. It is also available as a REDCap Registry through a research protocol.
  • Genetic testing to identify CCHS-related mutations in the PHOX2B gene involves step-wise testing with Step 1. PHOX2B Screening Test, Step 2. PHOX2B Sequencing Test, and Step 3. PHOX2B MLPA Test.
  • Physiologic and other clinical testing during wakefulness and sleep and other testing to evaluate patients in activities of daily living in keeping with the ATS 2010 Statement on CCHS.

Specific Instructions

The Rare Genetic Conditions Working Group (WG) acknowledges that (1) the Autonomic Nervous System Questionnaire (ANSQ) can be administered manually or through a Congenital Central Hypoventilation Syndrome (CCHS) REDCap Registry; (2) Genetic PHOX2B testing sites for step-wise testing are described in the 2010 American Thoracic Society (ATS) Statement on CCHS and are provided at www.genetests.org; and (3) the physiologic and autonomic testing would need to be provided in a laboratory with experience in polysomnography with application in wakefulness and sleep-and, ideally, in a center with extensive expertise in CCHS. The other clinical testing would need to be provided in a pediatric specialty program with extensive experience in ventilator management for children and if possible adults with disordered respiratory control and autonomic regulation.

Additionally, the WG recommends the PhenX Family History measure be used to capture information on family members in reference to the family tree in the ANSQ.

Protocol

Autonomic Nervous System Questionnaire (ANSQ):

First we are going to draw your family tree. Be sure to include any abortions (spontaneous and elective) and any infant deaths including sudden infant death syndrome (SIDS). (See step by step family tree diagram.)

Now that we’ve drawn your family tree, I’m going to ask you specific questions that you should answer first about the individual with CCHS (might be you or your child) and then about anyone you’ve described in your family tree.

Are you or any other adults (18 years of age or older) in your family:

Over 6’2?

Under 4’8?

Over 200 lbs?

Under 90 lbs?

Have any minors (under 18 years of age) in your family had atypical growth patterns?

Delayed growth?

Accelerated growth?

Have you or anyone in your family ever been diagnosed with obesity?

Yes ___ No ___

Do you or anyone in your family have growth hormone deficiency or excess?

Yes ___ No ___

Do you or anyone in your family have any known significant medical problems?

Yes ___ No ___

Remember when you answer these questions we would like to know if you ever experienced these problems at any time - as an infant, child or adult. Also, tell me first about you and then about any of the people you told me about when we drew the family tree.

Genetic Testing:

Genetic testing (stepwise) is used to identify a CCHS-related PHOX2B mutation (required to confirm the diagnosis of CCHS). If Step 1 testing is negative, then Step 2 testing should be performed. If Step 2 testing is negative, then Step 3 testing should be performed. Normal PHOX2B genotype is 20/20 reflecting the number of alanines on each allele. Patients with CCHS are heterozygous for a disease-causing PHOX2B mutation. This testing should be done via a CLIA-certified laboratory. Information regarding these laboratories is located on www.genetests.org

  • Step 1. PHOX2B Screening Test (also known as Fragment Analysis or Genotyping Analysis): identifies all polyalanine repeat expansion mutations (PARMs)(genotypes 20/24-20/33), the large frameshift non-PARMs (NPARMs), and somatic mosaicism. It is the only clinically available test that will identify low level somatic mosaicism.
  • Step 2. PHOX2B Sequencing Test: identifies all known PARMs (genotypes 20/24-20/33) and all NPARMs. Does NOT identify low level somatic mosaicism.
  • Step 3. PHOX2B MLPA Test: identifies whole gene or whole exon deletions and duplications.

Physiologic and other clinical testing:

Physiologic and other clinical testing that follows the 2010 ATS Statement on CCHS recommendations is optimal to diagnose and provide conservative management of affected patients, with aim for longitudinal follow-up and objective measures before and after pharmacological intervention.

  • Detailed recording in a pediatric respiratory physiology laboratory for documentation of hypoventilation or absent spontaneous breathing asleep (most severe in non-REM sleep) and in varied activities of daily living while awake over the course of 4 days and 4 nights to adequately represent the patient’s needs. A subset of individuals with CCHS will hypoventilate awake and asleep. Testing should be completed during spontaneous breathing as well as with artificial ventilatory support.
    • Tidal volume (pneumotachograph) measurement
      • In CCHS below 7 cc/kg (usually below 5 cc/kg and lower asleep)
      • Normal range in healthy controls is 7-10 cc/kg
    • Movement (respiratory inductance plethysmography) of the chest and abdomen
    • Respiratory frequency
      • In CCHS, respiratory rates will typically be above norms for age.
      • General ranges for healthy norms is provided below:
        • Birth to 6 weeks: 30-60 breaths per minute (bpm)
        • 6 months: 25-40 bpm
        • 3 years: 20-30 bpm
        • 6 years: 18-25 bpm
        • 10 years: 12-15 bpm
        • Adults: 12-20 bpm
    • Hemoglobin saturation with visible pulse waveform and beat-to-beat measures
      • In CCHS below 92% during sleep and, if awake hypoventilation, when awake
    • End tidal carbon dioxide with visible breath-to-breath measures
      • In CCHS above 50 mmHg during sleep, and if awake hypoventilation, when awake
    • ECG
      • In CCHS decreased heart rate variability and in a subset of cases sinus pauses
    • If possible, measures of blood pressure and cerebral oxygenation/regional blood flow should be included
  • Exogenous and endogenous ventilatory challenges in response to hypoxemia and hypercarbia (awake and asleep)
    • In CCHS lack of a consistent or sustained normal ventilatory or cardiovascular response to clinical challenges with Hypercarbia (5%)/Hyperoxia (95%), Hypercarbia (7%)/Hypoxia (14%), and Hypoxia (5 breaths of nitrogen).
  • 72-hour Holter recording annually to evaluate for cardiac sinus pauses
  • Neurocognitive testing
  • Evaluation for tumors of neural crest origin if PHOX2B genotype 20/28-20/33 or NPARM
  • Evaluation for Hirschsprung disease
  • Age and symptom-specific autonomic testing
    • Birth through adult Poincaré plots of r-r +1 vs. r-r (cigar pattern in CCHS), pupillometry (typically decreased pupillary response to light but PHOX2B genotype-specific), and peripheral skin temperatures (typically mildly reduced)6 years through adult: head-up tilt (typically uncoupling of blood pressure and heart rate and altered cerebral regional blood flow), thermoregulatory sweat test (typically altered sweating pattern and reduced peripheral skin temperature), heart rate-deep breathing, Valsalva maneuver, and more depending on child’s symptoms and ability to cooperate.
Personnel and Training Required

The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews. The interviewer should be trained to prompt respondents further if a "don’t know" response is provided.

Selection Rationale

Collecting data on Congenital Central Hypoventilation Syndrome (CCHS) in a standard fashion is critical to understanding the condition throughout childhood and longitudinally throughout adulthood and for treatment of individuals with this condition.

The Rare Genetic Conditions Working Group (WG) recommends following the American Thoracic Society (ATS) policy statement regarding CCHS as a method for identifying appropriate participants for clinical research and epidemiological studies. The WG also notes that completion of the Autonomic Nervous System Questionnaire (ANSQ), step-wise PHOX2B genetic testing, and physiologic (and other clinical) testing is high burden but essential to fully characterize the CCHS phenotype and provide genetic confirmation of the diagnosis.

Measure Name

Disorders of Respiratory Control with Inherent Autonomic Dysregulation

Release Date

April 30, 2015

Definition

The measure is used to assess dysregulation of the autonomic nervous system and whether the individual may have characteristic autonomic dysregulation as anticipated in congenital central hypoventilation syndrome (CCHS).

Purpose

Congenital central hypoventilation syndrome (CCHS) represents the extreme end of a spectrum of autonomic nervous system dysregulation, characterized by hypoventilation during sleep (and, in more severe cases, during wakefulness and sleep), with markedly diminished or absent ventilatory responses to hypoxia/hypercarbia, coupled with signs of autonomic dysfunction.
