Brief Summary
Hashimoto's thyroiditis (HT) is the most commonly observed inflammatory and autoimmune disease of the thyroid gland. Recent evidence has suggested that low-level laser therapy (LLLT) can improve thyroid function and reduce levels of thyroid peroxidase antibodies (TPOAb) in patients with hypothyroidism caused by chronic autoimmune thyroiditis. In the literature, data examining the effects of LLLT on oxidative stress level and quality of life in patients with HT is limited. The aim of the study is to examine the effects of LT4 treatment combined with LLLT on thyroid autoimmunity, oxidative stress and quality of life in patients with Hashimoto's diagnosis.

Outcome Measures
Primary Outcomes (6)
Oxidative Stress Levels
Biochemical parameters will be taken from the patient file routinely requested by the physician. For routine or whole blood analysis, leftover serum samples will be collected from the blood taken after fasting for 10-12 hours and the separated serum samples will be kept in a -80 °C refrigerator until the analysis day. The analysis of the collected samples will be examined in the Biochemistry Laboratory of Istanbul Medipol University. Oxidative Stress Index (OSI) will be calculated by measuring Total Oxidant Level (TOS) and Total Antioxidant Levels (TAS).
3 months
Malondialdehyde (MDA)
For routine or whole blood analysis, leftover serum samples will be collected from the blood taken after fasting for 10-12 hours and the separated serum samples will be kept in a -80 °C refrigerator until the analysis day. The analysis of the collected samples will be examined in the Biochemistry Laboratory of Istanbul Medipol University. Oxidative stress biomarkers will be examined.
3 months
Nitric oxide (NO)
For routine or whole blood analysis, leftover serum samples will be collected from the blood taken after fasting for 10-12 hours and the separated serum samples will be kept in a -80 °C refrigerator until the analysis day. The analysis of the collected samples will be examined in the Biochemistry Laboratory of Istanbul Medipol University. Oxidative stress biomarkers will be examined.
3 months
Superoxide dismutase (SOD)
For routine or whole blood analysis, leftover serum samples will be collected from the blood taken after fasting for 10-12 hours and the separated serum samples will be kept in a -80 °C refrigerator until the analysis day. The analysis of the collected samples will be examined in the Biochemistry Laboratory of Istanbul Medipol University. Oxidative stress biomarkers will be examined.
3 months
Catalase (CAT)
For routine or whole blood analysis, leftover serum samples will be collected from the blood taken after fasting for 10-12 hours and the separated serum samples will be kept in a -80 °C refrigerator until the analysis day. The analysis of the collected samples will be examined in the Biochemistry Laboratory of Istanbul Medipol University. Oxidative stress biomarkers will be examined.
3 months
Glutathione (GSH)
For routine or whole blood analysis, leftover serum samples will be collected from the blood taken after fasting for 10-12 hours and the separated serum samples will be kept in a -80 °C refrigerator until the analysis day. The analysis of the collected samples will be examined in the Biochemistry Laboratory of Istanbul Medipol University. Oxidative stress biomarkers will be examined.

Study Arms (2)
Low Level Laser Therapy Group
ACTIVE COMPARATORLow Level Laser Therapy (LLLT): Low-level laser therapy will be applied to the cases in addition to LT4 hormone replacement therapy. LLLT group will be treated using a continuous wave GaAIAs type diode laser (Intelect® Mobile Laser, Model No: 2779, Production Year: 2016; Chattanooga Group) device in the treatment area of 0.07 cm2. Continuous mode at 850 nm wavelength, 100 mW output power,1.43 W/cm2 power density and 28.57 J / cm2 energy density will be used.
Sham Group
SHAM COMPARATORProbes were placed in the sham laser group in a similar way as in the treatment group.
Interventions
Eight target points (superior, mediolateral, inferior border of the right and left thyroid lobes, right and left sides of the isthmus) will be marked with a surgical pen by determining the thyroid borders on the skin by thyroid ultrasonography by the specialist physician. Low-level laser (28.57 J / cm2) fixed applications will be made on the thyroid gland, approximately 1 cm from each other. In practice, the patient's neck will be maintained in the extension position. Each application will last 20 seconds and the radiant energy will be 2 J, the tip of the laser will be kept in contact with the skin and upright. Duration of treatment is 6 sessions 2 days a week. The cumulative dose will be 96 J.
Probes were placed in the sham laser group in a similar way as in the treatment group. The screen of the laser device was active; however, the energy was set as 0 J and the power as 0 mW , respectively,and the same operations were also performed.
Eligibility Criteria
You may qualify if:
- Cases between the ages of 18-65 who applied to the Kosuyolu Istanbul Medipol Hospital Endocrinology and Metabolic Diseases Clinic between 2020-2021 and diagnosed as "Hashimoto Thyroiditis" by a specialist physician will be included in the study.
You may not qualify if:
- Acute infection
- Use of immunosuppressants, immunostimulants and drugs that interfere with the production, transport, and metabolism of thyroid hormones
- Thyroid nodules

- Serious illness
- History of exposure to ionizing radiation and/or neoplasia in the cervical region
- Malignancy and a history of thyroid surgery
- Hypothyrodism caused by postpartum thyroiditis
- Pregnancy and breastfeeding period
- Identification and diagnosis of the cases with neurological and psychiatric disorders.
