Background: Hypophosphatasia (HPP) is the rare inherited metabolic disorder resulting from loss-of-function mutation(s) in the tissue-nonspecific alkaline phosphatase (TNSALP) gene. TNSALP deficiency can cause a spectrum of complications in children including premature deciduous tooth loss, rickets, poor growth, and compromised physical function. We previously reported that children, 5–12 years old, with HPP and treated with asfotase alfa, a recombinant bone-targeted huma...

Introduction: Prader-Willi Syndrome (PWS), a common syndromic form of childhood obesity, is characterized by failure-to-thrive during infancy followed by progressive hyperphagia and obesity in childhood. The pathogenesis of hyperphagia and weight-gain in PWS is poorly understood and management strategies have had variable and limited success. Several studies support an etiological contribution of dysbiotic gut microbiota in the metabolic derangements of obesit...

Background: Recent research has demonstrated earlier testicular and pubertal development in Western boys. New ultrasound-based references of testicular growth in Norwegian boys are now available. Population specific references for FSH, LH and sex steroid hormones have not been previously available in Norwegian children and adolescents.Objective and hypotheses: We aimed to provide an elaborate description of pubertal development in a sample of contemporar...

Purpose: Anorexia nervosa (AN) increases the risk of impaired bone health, low areal bone mineral density (aBMD), and subsequent fractures. This study investigated the long-term effects on bone and biomarkers in young women with AN.Methods: Twenty-five Swedish female AN patients, median age 21.0 years (16.1 to 24.3 years), median BMI 15.4 kg/m2, were included, 22 patients completed a high-energy in-patient treatment for ...

Introduction: The survival rates for childhood cancer have significantly increased over the past decades but the management of treatment-related complications remains challenging. Thus, the introduction of novel drugs requires careful investigation of potential off-target side effects. The developing skeleton is severely affected by the anticancer treatment which may result in growth retardation and short stature. Venetoclax is a selective Bcl-2 inhibitor whic...

Aim: To determine whether adolescents born before 28 gestational weeks have an increased risk for renal impairment.Methods: Swedish infants, born before 28 gestational weeks in 2001 and 2002, were identified from a local register. A total of 16 children, 12 females and 4 males, were examined at 16–17 years of age with 51Cr-EDTA clearance. A comparison group (n=26) was used.Re...

Background: The incidence of Type 1 diabetes (T1D) is rising globally and fractures are common.Objective: To investigate bone health in young females with a T1D duration of at least 10 years in relation to healthy, matched controls.Subjects: Twenty-three Swedish females, aged 19.2– 27.9 years, with a T1D duration of ≥10 years, were recruited from the Swedish National Dia...

Purpose: Modified ketogenic diet (MKD) is one treatment option for intractable epilepsy and metabolic conditions such as glucose transporter type 1 deficiency syndrome (GLUT1-DS) and pyruvate dehydrogenase complex (PDC) deficiency. MKD is a less restrictive diet than the classical ketogenic diet (KD) and thus more tolerable. Childhood is an important period for bone acquisition. Some studies indicate a negative effect on bone mass during KD treatment, probably as a consequence...

Purpose: Modified ketogenic diet (MKD) is one treatment option for intractable epilepsy and metabolic conditions such as glucose transporter type 1 deficiency syndrome (GLUT1-DS) and pyruvate dehydrogenase complex (PDC) deficiency. MKD is a less restrictive diet than the classical ketogenic diet (KD) and thus more tolerable. Some studies indicate that prolonged KD treatment can negatively affect linear growth in children. Long-term data is missing regarding the effects of MKD ...

Background: It has been reported that short-term increases of the bone formation markers intact amino-terminal propeptide of type I procollagen (PINP), bone-specific alkaline phosphatase (BALP) and osteocalcin display different temporal patterns. In adults, the biphasic model of GH action in bone remodelling shows that GH treatment results initially in an increased bone resorption with a concomitant bone loss, which later on is followed by increased bone formation. In children...
