Congenital Hypothyroidism: The Use of a TSH Cut-off Limit of 6mU/L and the ESPE Criteria for LT4 Treatment Leads to the Diagnosis of Mild but mostly Permanent Forms of Hypothyroidism

Background: Since the initiation of neonatal screening programs for Congenital Hypothyroidism (CH) in the 1970’s, a gradual decrease of TSH cut-off limits has been observed worldwide. Nevertheless, lack of universal consensus has led to wide variation of cut-off limits and LT4 therapy criteria among screening programs, even within the same country. The Greek neonatal CH screening program is carried out by a single laboratory that uses one of the lowest cut-off limits worl...

Lowering of the TSH cut-off Limit Substantially Alters Universally Accepted Key Features of Congenital Hypothyroidism. Reconsideration of the Use of FT4 levels for Diagnosis and Treatment

Background: The term Congenital Hypothyroidism (CH) describes children with subnormal thyroid hormone levels present at birth. According to literature, CH has an incidence of ~1:1500–1:3000 births with a clear predominance of females (female:male ratio 2:1) and is mainly caused by thyroid dysgenesis (80%). Low FT4 levels have been used as important criteria for CH diagnosis and treatment initiation. The Greek neonatal CH screening program has followed the TSH cut-off lowe...

Background: A high frequency of extrathyroidal congenital anomalies has been reported in infants with congenital hypothyroidism (CH) detected by neonatal screening. Current ESPE guidelines suggest that congenital malformations, underlying dysmorphic syndromes and psychomotor and language development should be sought for and monitored in CH patients. The identification of co-existing nosologies and malformations is helpful not only for clinical purposes but also for uncovering ...
