Suppression of Bone Turnover and its Determinants in Children Receiving Bisphosphonate Therapy

Kyriakou Andreas , McNeilly Jane D , McMillan Martin , Shaikh Guftar M , Mason Avril , Ahmed Syed Faisal

Background: Bisphosphonate therapy (BPT) reduces osteoclast activity and may be associated with adynamic bone turnover. The extent of suppression of bone turnover and its determinants are unclear.Method: Markers of bone metabolism were evaluated in 15 children (9M/6F) undergoing BPT for osteoporosis. The median age at first biochemical assessment was 10.8 years (0.16, 16.3). Serum type I collagen cross-linked C-telopeptide (CTX), alkaline phosphatase (AL...

A Case of Vitamin D Dependent Rickets Type 1 with a Novel Mutation in CYP27B1 (25-OH Vitamin D-1-α-Hydroxylase) Gene

Ozcabi Bahar , Evliyaoglu Olcay , Ercan Oya , Tahmiscioglu Feride , Jaferova Sevinc , Oruc Cigdem , Adrovic Amra

Background: Vitamin D dependent type 1 rickets is a rare, autosomal-dominantly inherited disorder due to an inactivating mutation in CYP27B1 (25-OH vitamin D-1-α-hydroxylase) gene. It is characterized by early onset of rickets with hypocalcemia. We report a boy admitted with symptoms of hypocalcemia and who carried a novel mutation in CYP27B1 gene.Case: The patient was admitted with tetany at the age of 12 months. When he had his first convulsion, h...

Risedronate Use in Duchenne Muscular Dystrophy: a Pilot Randomised Control Trial

Mc Sweeney Niamh , Mc Kenna Malachi , van der Kamp Susan , Kilbane Mark , Mc Donnell Ciara , Murphy Nuala , Webb David , Lynch Bryan

Background: Boys affected with Duchenne Muscular Dystrophy (DMD) have lower bone mineral density compared with unaffected boys.Objective and hypotheses: We sought to determine the effects on bone mineral density (BMD) of 1 year treatment with Risedronate and calcium/vitamin D supplementation vs calcium/vitamin D supplementation alone.Method: BMD was measured at spine and whole body. We obtained early morning fasting blood samples f...

Outcomes of Vitamin D Analogues and Phosphate Supplements in Patients With Hereditary Hypophosphatemic Rickets , Comparison With Non-Treated Patients

Boros Emese , Rothenbuhler Anya , Heinrichs Claudine , Brachet Cecile , Esterle Laure , Kamenicky Peter , Harvengt Pol , Brailly-Tabard Sylvie , Haidar Hazar , Gaucher Celine , Silve Caroline , Gossiome Charles , Wicart Philippe , Duplan Martin Biosse , Courson Frederic , Chaussain Catherine , Linglart Agnes

Background: Hereditary Hypophosphatemic Rickets (HHR) is caused by persistently elevated FGF23 resulting in renal phosphate wasting and decreased 25 vitamin D hydroxylation. Treatment with vitamin D analogues (VDA) has been added to phosphate supplements in the late seventies.Objective and hypotheses: Our objective was to evaluate the outcomes of VDA and phosphate supplements in adult patients with HHR in comparison with patients who did not receive VDA ...

Hyperostosis-Hyperphosphataemia Syndrome: Shortening a Diagnostic Odyssey

Kothandapani Jaya Sujatha Gopal , Offiah Amaka , Hobson Sally , Arundel Paul

Introduction: Hyperostosis-hyperphosphataemia syndrome (HHS) is a rare autosomal recessive condition caused by inactivating mutations in the GALNT3 gene, characterised by elevated serum phosphate and 1,25(OH)2 vitamin D, increased urinary tubular reabsorption of phosphate and hyperostosis of long bones.Case report: A 15-year-old boy (weight +1.05 SD; height −0.1 SD) with consanguineous parents of Palestinian descent, presented w...

Severe Osteogenesis Imperfecta and Epidermolysis Bullosa Simplex Caused by FKBP10 Mutation: New Case

Guven Ayla , Kavala Mukaddes , Akarsu A Nurten

Background: Mutations in genes encoding type 1 procollagen (T1PC) and proteins responsible for posttranslational modifications of the T1PC heterodimer may result in brittle bone disorder osteogenesis imperfecta (OI). FKBP65 is a known chaperone for type I procollagen and encoded by FKBP10. Autosomal-recessively inherited epidermolysis bullosa simplex and moderately severe OI caused by FKBP10 mutation reported in consanguineous Turkish and Mexican families.</p...

Osteogenesis Imperfecta Type I Caused by a Novel Mutation in the Start Codon of the COL1A1 Gene in a Korean Family and the Course of Pamidronate Treatment for 1 Year

Cho Sung Yoon , Jin Dong-Kyu , Yu Jae-Hong , Han Heon-Seok

Background: A 3-year-old boy appeared healthy at birth and did not experience any fractures until 12 months of age. Blue sclera, frequent fractures without adequate trauma, nearly normal stature, the absence of dentinogenesis imperfecta, no bony deformity, and no limitation of mobility were characteristics suggestive of OI type I that were observed in the patient. The patient’s mother had blue sclera and a history of frequent fracture episodes until the age of 15 years.</...

Early Calcinosis Cutis, Short Stature and Brachydactyly: a Case Evolution

Riano-Galan Isolina , Rodriguez-Dehli Cristina , Huidobro-Fernandez Belen , Alvarez M Victoria , Flores Silvia Avila , Toral Joaquin Fernandez

Background: Subcutaneous calcification is a rare clinical symptom in infancy. Progressive evolution and association with brachydactyly could be indicators of Albright hereditary osteodystrophy (AHO). In clinical practice, AHO is difficult to diagnose because of clinical heterogeneity. Typical features of AHO without any evidence of hormone resistance are termed pseudopseudohypoparathyroidism (PPHP; OMIM 612463).Case report: Male patient referred to study...

Does Vitamin D Affect Mean Platelet Volume Values or Not

Bulan Keziban , Dogan Murat , Kaba Sultan , Aslan Oktay

Objective: Platelets play a key role in the development and progression of cardiovascular disease. The degree of platelet activation may be assessed by platelet indices such as platelet count, mean platelet volume (MPV) and platelet distribution width (PDW). In addition, both epidemiological and in-vitro studies have linked vitamin D deficiency to enigmatic disease including cardiovascular disease however a clear mechanistic link remains missing. In present study, we ...

Bone Size and Bone Mineral Content in Adolescents and Young Adults with Eating Disorders

Mason Avril , Shepherd Sheila , Oakley Charlotte , Thrower Michelle , Kyriakou Andreas , Shaikh Guftar , Ahmed Syed Faisal

Background: There is growing concern about the impact of eating disorders on the bone heath during adolescence where peak bone mass acquisition is of paramount importance.Method: A total of 85 patients (77F/8M, 75% anorexia nervosa(AN) and 25% atypical eating disorder), median age 15.2 years (range, 10.9–19.8) and median BMI SDS −1.3 (−4.7 to 0.8) attended the bone densitometry service between Jan 2009 and Dec 2013 for total body (TB) an...

Infantile Hypercalcemia: Still a Diagnostic and Therapeutic Enigma

Boyadzhiev Veselin , Bliznakova Dimitrichka , Iotova Violeta , Schlingmann Karl

Background: Hypercalcemia requires new investigation pathways after publishing the mutations of the CYP24A1 gene. Furthermore, diagnostic puzzles connected to it still remain.Objective and hypotheses: We present a 1.5-years-old girl with infantile hypercalciuria who has been followed-up since she was 4 months old. The child is born from uneventful pregnancy, normal delivery, on term with weight 3600 g and length 52 cm. Two months after birth she became i...
