The Effect of Iron Overload, Oxidative Stress and Dyslipidemia on Glucose Level and Thyroid Function in Patients With Abnormal Hemoglobinopathy

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.

Detailed Description

Severe anemia due to defect in the synthesis of hemoglobin and hemolysis can endanger the life of β- thalassemia major (β-TM) patients and sickle cell anemia; therefore, the span and patient's quality of life is highly dependent on regular blood transfusion. Nonetheless, blood transfusion causes iron accumulation in the patients. Excess iron deposits in vital organs, such as liver, heart and endocrine glands, result in their malfunction. Endocrinopathies account as one of the most common iron overload complications. Oxidative stress is a major mechanism contributing to the progression of the disease in TDT. Iron overload enhances oxidative stress in patients with TDT. Iron is recognized to be a catalyst in developing reactive oxygen species (ROS).

MDA is an eosinophilic enol compound that reacts with the structural and functional cellular protein to generate toxic lipoxidation end product destined for cellular damage of the affected organs. It is used as a sensitive biomarker for oxidative stress. Disturbances in serum lipids and carbohydrates homoeostasis as well as OS were documented in β-TM and sickle cell anemia. Increase in serum levels total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and decrease in high-density lipoprotein cholesterol (HDL-C) are the well-known causative factors and predictors of CHD development and endocrine abnormality

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

N/A

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

The study will be done in Assiut University Hospital on 50 cases as Group (A): cases diagnosed as beta thalassemia major Group (B): healthy individuals (control)

All patients will be subjected to full clinical history, examination and investigation. -investigation will include:

  • laboratory test:
  • CBC. -TSH, T4, T3. -serum oxidative stress marker (MDA).
  • glucose level.
  • cholesterol, triglycerides, HDl, LDL

Description

Inclusion Criteria:

- age 18 and above.

-patients diagnosed according to physical examination and results of laboratory tests as beta thalassemia major. -patient under gradual blood transfusion and iron chelating therapy. -Gender and age matched healthy controls with normal serum lipid, glucose level and thyroid function will enrolled in this study as the control group

Exclusion Criteria:

  • age under 18 years.
  • patient diagnosed with DM or those taking pharmacological agents such as steroids, insulin and lipid lowering drugs

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
correlation between oxidative stress and endocrine dysfunction in patients with hemoglubinopathy
Time Frame: 1 year
  1. The effects of iron overload and oxidative stress and dyslipidemia on glucose level and thyroid function in patients with abnormal hemoglobinopathy.
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Using of MDA level as a marker of oxidative stress
Time Frame: 1 year
Malondialdehyde as a marker of oxidative stress

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Anticipated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 1, 2022

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
December 1, 2023

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
