Introduction: Generation of neutralizing antibodies (Nab) is a complication in enzyme replacement therapies and can lead to loss of treatment efficacy. Asfotase alfa (AA) was recently approved as the first replacement therapy in severe hypophosphatasia (congenital deficiency of alkaline phosphatase [TNSALP]). We report a case of neutralizing antibody mediated loss of efficacy of AA treatment in hypophosphatasia and the successful result of immune tolerance ind...

Background: Vitamin D (25OHD) insufficiency is becoming a public health issue. Adequate 25OHD status during pregnancy may influence the health status of the offspring.Objective: To evaluate the levels of 25OHD from gestation to 12 years, assessing seasonality and intake.Material and methods: Data were obtained from 485 pregnant mothers recruited in Asturias between 2004-2007 and th...

Background: In minipuberty, the male hypothalamic-pituitary-gonadal (HPG) axis is transiently activated triggering a surge in reproductive hormones causing growth of the genitalia. Longitudinal individual growth of the infant penis during minipuberty and associations to the HPG axis and IGF-I have not been thoroughly assessed.Aim: To describe the development of penile length and width as well as their relation to serum c...

Introduction:Premature adrenarche (PA) is the most common cause of premature pubic and axillary hair growth before the age of 8 in girls. At the time of diagnosis, the height and bone age of the cases with premature adrenarche were determined to be higher than their peers. The long-term effects of advanced bone age on the final length of the cases are controversial. In this study, it is aimed to share the long-term follow-up data of the cases diagnosed with pr...

Background: Resistance to thyroid hormone alpha (RTH-α) is characterized by varying degrees of symptoms and findings related to hypothyroidism. However, diagnosis is difficult since thyroid-stimulating hormone (TSH) levels are normal. Free triiodothyronine (fT3) and free thyroxine (fT4) levels can also be normal, but normo- or macrocytic anemia is generally present in the reported cases. L-thyroxine can alleviate some symptoms; however, there is limited ...

Introduction: Because of the associations and links between abnormal placental weight and both fetal and maternal disorders, it is important to have the national normal standard for placental weight as a normality reference.Aims: To find out the national placental weight standards for babies born between 37th and 43rd weeks of gestation in all groups of males and females babies born AGA, SGA, and LGA.<p class="abstex...

Prematurity is a risk factor for significant hypoglycemia even in infants born to non-diabetic mothers (INDM) which could lead to postnatal growth abnormalities. This study evaluated the growth pattern from birth until the age of 2 years of 51 INDM who were born preterm or near term and admitted with significant hypoglycemia. Anthropometric measures (z scores) from birth, 2,4,6,12,18 and 2 years were measured in 51 INDM who admitted with neonatal hypoglycemia (Plasma value les...

Abnormal postnatal patterns of linear growth and weight gain have been reported in infants born to mothers with gestational diabetes (IDM). We evaluated the growth pattern from birth to the age of 2 years of 79 IDMs who were born at or near term with significant hypoglycemia. Anthropometric measures (z scores) from birth, 2,4.6,12,18, and 2 years were measured in 79 IDM who presented with significant neonatal hypoglycemia (Plasma value less than 20-25 mg/dL (1.1-1.4 mmol/L)) t...

Background: X-linked hypophosphatemia (XLH) is a rare genetic disorder of phosphate metabolism caused by mutations in the PHEX gene. XLH patients exhibit short stature and skeletal deformities, which are caused by defective bone mineralization site leading to increased porosity and decreased matrix stiffness. Bone mineral density measurements have been shown to be insensitive to the cumulative bone alterations. The velocity of the first arriving signal (vFAS) ...

Introduction: An activating mutations in the ABCC8 gene cause both transient and permanent neonatal diabetes mellitus (DM) or MODY 12. In relation to the variant in the ABCC8 gene, patients may also present with either neonatal hyperinsulinism and/or DM later in life. Besides, the same variant can cause different phenotypic features among family members. Response to the sulfonylurea treatment may vary between patients.<...
