Protocol summary

Study aim
Determining the therapeutic effect of Thymex supplement syrup on autism symptoms and the level of blood inflammatory factors in autistic children
Design
A controlled, parallel-group, double-blind, randomized, phase 3 clinical trial on 50 patients. The randomization method is random allocation. The randomization unit is an individual. The randomization tool is a sealed envelope.
Settings and conduct
For this study, we are considering Thymex 140 ml syrup. Each 100 ml of this syrup contains 660 mg of dry thyme plant extract. After obtaining the consent form from the parents of the patients, we have considered, for children aged 3 to 6 years, 3 times a day and 2.5 ml each time, and for children 6 to 10 years old, 3 times a day and 5 ml each time, for 1 month. The study is randomized, double-blind, that is, the participant, the clinical caregiver and the researcher do not know which patient will take the drug or placebo. Both groups receive standard autism treatment. Using the Gilliam questionnaire and measuring the level of inflammatory factors in the blood of the participants, the result of the intervention will be evaluated.
Participants/Inclusion and exclusion criteria
Children aged 3 to 10 with autism who do not have drug interactions due to the presence of a concurrent disease and the use of medication for its treatment, and who follow the study's consumption pattern and are willing to cooperate until the end of the study and are available.
Intervention groups
The intervention group includes children aged 3-10. Children aged 3-6 take 2.5ml of syrup 3 times a day. children aged 6-10 take 5ml of syrup 3 times a day. Both groups receive standard autism treatment.
Main outcome variables
Level of blood inflammatory factors and behavior of autism patients

Randomization (investigator's opinion)
Randomized
Randomization description
Patients will be gradually entered into the study in the treatment method and will be assigned to two intervention and control groups based on the random assignment method. For this purpose, we put the number of 50 cards with the letter A on 25 of them and the letter B on the other 25 in an envelope and randomly take out one card for each patient. The letter that comes out shows the group of the patient. Note that the doctor conducting the trial and the patient do not know about the syrups and B until the end of the study and the results, the study is double-blind.The randomization method is random allocation. The randomization unit is an individual. The randomization tool is a sealed envelope. The concealment is that cards A and B are placed in a sealed envelope and the allocator does not know the contents of the cards until the time of allocation.
Blinding (investigator's opinion)
Double blinded
Blinding description
The participant in the study and the physician conducting the clinical trial and the researcher as well as the outcome assessor in this study are blinded. Medicine and placebo will be provided in the same packaging from the pharmaceutical company. Attributing the drug and placebo to A and B is the responsibility of the drug distributor.

Intervention groups

1

Description
Intervention group: There are two types of Thymex syrup of Iran Darouk brand available in Iran, and for this study, we consider Thymex syrup of 140 ml Each 100 ml of Thymex Syrup contains 660 mg of Thymus vulgaris dry extract. The intervention group includes children with autism aged 3 to 10 years, children with autism 3 to 6 years old consume syrup 3 times a day and each time 2.5 ml, which is equivalent to a teaspoon, and children People with autism aged 6 to 10 years consume syrup 3 times a day and each time 5 ml, which is equivalent to two teaspoons. This group, at the same time as receiving Thymex syrup, receives the common treatment of autism, which depending on the patient can include drugs such as Risperidone, Aripiperazole or Methylphenidate. After 1 month of taking the drug according to the mentioned pattern, we will check the autistic behavior of the affected children by presenting a questionnaire based on the symptoms of autism to the parents of the affected. In order to investigate inflammatory markers and oxidative stress and to know the effect of the above drug on the levels of these markers, it is necessary to take a blood sample before the start of the study and a blood sample at the end of the 1-month study. The mentioned inflammatory factors are TNF-a and IL-1b, which are measured using an ELISA kit. The desired oxidative stress factors are malondialdehyde (MDA), antioxidant capacity (Total antioxidant capacity) and nitrite.

Description
Control group: It includes children with autism between the ages of 3 and 10, who, like the intervention group, also receive common autism treatment, which, depending on the patient, can include drugs such as Risperidone, Aripiprazole, or Methylphenidate. At the same time, the members of the control group will receive the placebo, which is in the form of a syrup and made on the basis of ineffective medicinal substances, without the patient, researcher and project manager being informed. After 1 month of taking placebo according to the mentioned pattern, we will check the autistic behavior of the affected children by presenting a questionnaire based on the symptoms of autism to the parents of the affected. In order to investigate inflammatory markers and oxidative stress and to know the effect of the above drug on the levels of these markers, it is necessary to take a blood sample before the start of the study and a blood sample at the end of the 1-month study. The mentioned inflammatory factors are TNF-a and IL-1b, which are measured using an ELISA kit.
