May 3, 2026 updated by: Norhan Elsayed Abdellah, Sohag University

Endocrinal Dysfunction Among Children With Dilated Cardiomyopathy at Sohag University Hospital

All patients in this study will be subjected to the following (as detailed in the attached patient's data sheet).

  1. Clinical History: focusing on:

    • Socio-demographic factors, especially age, gender, family history, and degree of consanguinity.
    • Cardiac symptoms, such as feeding difficulties in the infant, exercise intolerance in older children, fatigue, dyspnea on exertion, heart failure symptoms.

  2. Thorough clinical examination: focusing on:

    • General condition.
    • Anthropometric measures (weight, height, and body mass index).
    • Vital signs (Including HR, BP, SO2, RR, Body temperature).
    • Cardiac examination (including any associated murmur, signs up heart failure).

  3. Severity of heart failure in children with dilated cardiomyopathy For all patients, they were classified according to Children's Ross HF classification.

    Children's Ross HF classification is as follows[17]:

    Class I: asymptomatic cases.

    Class II: mild tachypnea or diaphoresis with feeding in infants, dyspnea on exertion in older children.

    Class III: marked tachypnea or diaphoresis with feeding in infants, marked dyspnea on exertion, and prolonged feeding times with growth failure.

    Class IV: tachypnea, retractions, grunting, or diaphoresis at rest are examples of symptoms.

  4. Data collection: according to attached checklist for every patient involved in the study

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Dilated cardiomyopathy is defined as "dilatation and impaired contraction of the left or both ventricles with normal wall thickness" . It is characterized by systolic dysfunction with reduced myocardial contractility . DCM is the third leading cause of heart failure in pediatrics 3. The exact etiology of DCM is unknown in more than half of the cases and the term idiopathic DCM is used after exclusion of all the well-known etiologies of DCM as viral infections, autoimmune, genetic, endocrinal, and metabolic diseases .

DCM is typically diagnosed when patients present with heart failure symptoms, typically related to left ventricle systolic dysfunction, but right systolic dysfunction may accompany left ventricle failure . About 8-15% of patients will present with cardiac arrest, or with near-arrest requiring emergent resuscitation. In the remainder of patients, the most common symptom is shortness of breath (50%), followed by gastrointestinal upset and fatigue that is reported in a third of patients. Symptoms of an upper respiratory tract infection are also common. Echocardiography is the gold standard for diagnosis of DCM .

    • Socio-demographic factors, especially age, gender, family history, and degree of consanguinity.
    • Cardiac symptoms, such as feeding difficulties in the infant, exercise intolerance in older children, fatigue, dyspnea on exertion, heart failure symptoms.

  2. Thorough clinical examination: focusing on:

    • General condition.
    • Anthropometric measures (weight, height, and body mass index).
    • Vital signs (Including HR, BP, SO2, RR, Body temperature).
    • Cardiac examination (including any associated murmur, signs up heart failure).

  3. Severity of heart failure in children with dilated cardiomyopathy For all patients, they were classified according to Children's Ross HF classification.

    Children's Ross HF classification is as follows[17]:

    Class I: asymptomatic cases.

    Class II: mild tachypnea or diaphoresis with feeding in infants, dyspnea on exertion in older children.

    Class III: marked tachypnea or diaphoresis with feeding in infants, marked dyspnea on exertion, and prolonged feeding times with growth failure.

    Class IV: tachypnea, retractions, grunting, or diaphoresis at rest are examples of symptoms.

  4. Data collection: according to attached checklist for every patient involved in the study

  5. Investigations: focusing on

    • Laboratory investigations (IGF-1, free T3 and T4, TSH, morning serum cortisol and ACTH, 25 OH vit D, total and ionized calcium, serum parathyroid hormones levels, serum prolactin, serum electrolytes as Na, K). Samples to be withdrawn from cases and controls at 9:00 a.m. at the Pediatric Cardiology Unit, Sohag University Hospital.
    • Echocardiography assessment including:

    Ejection fraction

    Fractional shortening

    Left ventricular end systolic diameter

    Left ventricular end diastolic diameter

    Mitral valve closure to opening time

    Left ventricular ejection time

    Mitral valve ejection

    Mitral valve area

    E/A ratio Mitral valve

    Myocardial performance index of Left ventricular

  6. Possible Therapeutic Modalities given to patients in the study Medical treatment (e.g .Anti-failure medications: Diuretics, ACE inhibitors,..etc.)

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria
