Objectives: The relationship between elevated ferritin levels and metabolic abnormalities in PCOS patients, and whether ferritin is a cause or a consequence, is still debated. This study aimed to evaluate the impacts of the fourth generation combined oral contraceptive containing ethinyl estradiol/drospirenone (EE 30 mcg/DRSP 3 mg), known for its favorable metabolic profile and lower side effect risk, on iron metabolism in PCOS patients, while also exploring the potential relationship between metabolic parameters and iron status.

Methods: The retrospective analysis was conducted on 81 women aged 18-45, diagnosed with PCOS according to the Rotterdam criteria and treated with EE/DRSP for six months.

In light of research indicating that normal TSH levels do not necessarily reflect clinical euthyroidism in hypothyroid patients, and given the patient dissatisfaction with levothyroxine (LT4) monotherapy, we evaluate the response to weight loss treatment in patients with obesity and primary hypothyroidism who are euthyroid under LT4 therapy, with a focus on weight and metabolic parameters. The retrospective study included 138 subjects with obesity (BMI ≥ 30 kg/m), 69 women with hypothyroidism on levothyroxine, and 69 age- and BMI-matched women without thyroid disease. Secondary causes of obesity, medications that may affect thyroid functions and metabolic parameters, chronic and oncological disease, pregnancy, TSH outside the reference range, follow-up periods of less than one year, and bariatric surgery were the exclusion criteria.

We aim to investigate the influences of the treatment choice on permanent hypothyroidism occurring after SAT and whether there are predictive factors for the development of permanent hypothyroidism.
