Introduction: Despite normal thyroid-stimulating hormone serum levels, up to 60% of hypothyroid patients are dissatisfied with the treatment. Animal studies suggest that the persistence of symptoms may derive from peripheral hypothyroidism. Combination treatment with levothyroxine and liothyronine is a theoretically plausible solution but its efficacy is still questionable.Aim: To evaluate the effects of personalized twice-daily combination therapy on pe...

Despite an accurate management, in about 20% of hypothyroid patients showing an increased need for oral levothyroxine (LT4), the leading cause of treatment refractoriness remains unknown. Some studies hypothesized the relationship between gut microbiota composition and thyroid homeostasis, but the possible involvement of microflora in the efficacy of LT4 treatment has not been evaluated yet, and this represents the aim of our study. We examined the faecal microflora compositio...

Thyroid hormone resistance syndrome(THRS) occurs in 1:40000 live births and can be diagnosed after a period of enigmatic changes in thyroid hormones(TH). Patients may be clinically euthyroid, have clinical hypo or hyperthyroidism. Mostly, it is an autosomal dominant disease due to germline mutations in THRβ-gene(exons 7-10). Resistance to peripheral action of TH leads to absence of TSH suppression (which can be normal/elevated) despite elevated fT4 and fT3.<p class="a...

Objective: In differentiated thyroid carcinoma (DTC), TSH suppression with levothyroxine (L-T4) is a standard treatment for reducing tumor recurrence after total thyroidectomy. This study aims to evaluate the effect of long-term TSH suppression on the development of sarcopenia and frailty in elderly patients with DTC.Method: Seventy patients aged 60 years and older with stable TSH levels during the last year and under L-T4 due to DTC were included in the...

Introduction: Molecular testing is being increasingly used to detect malignancy in indeterminate thyroid nodules (Bethesda 3 & 4) which pose diagnostic dilemma. Long non-coding RNAs are crucial for metastasis, angiogenesis, and tumour growth of various cancers. Clinical utility of plasma lncRNAs as non-invasive diagnostic markers for thyroid cancer especially in indeterminate nodule remains unexplored.Methodology: We selected lncRNAs relevant to thyr...

The presence and the role of CD20+ T cells in humans has been described in autoimmune disorders such as multiple sclerosis and rheumatoid arthritis. In healthy subjects, CD3+CD20+ T cells are detected in all lymphatic organs and in the cerebrospinal fluid and represent about 5% of circulating T cells. Some reports described their production of high levels of IL-17A and/or IFN-γ. This study was aimed at investigating the behavior of CD3<sup...
