Homocysteine (Hcy) is thiol group containing the amino acid, which naturally occurs in all humans. Hcy is degraded in the body through two metabolic pathways, while a minor part is excreted through kidneys. The chemical reactions that are necessary for degradation of Hcy require the presence of the folic acid, vitamins B6 and B12. Consequently, the level of the total Hcy in the serum is influenced by the presence or absence of these vitamins. An elevated level of the Hcy, hyperhomocysteinemia (HHcy) and homocystinuria are connected with occlusive artery disease, especially in the brain, the heart, and the kidney, in addition to venous thrombosis, chronic renal failure, megaloblastic anemia, osteoporosis, depression, Alzheimer's disease, pregnancy problems, and others...

Adjuvant aromatase inhibitor (AI) therapy, for hormone receptor-positive breast cancer, in postmenopausal women is associated with bone loss, leading to an increased risk of fractures. Denosumab, an antibody raised against the receptor activator of nuclear factor-κB ligand, has been proven to protect against AI-induced bone loss. Hence, we aimed to determine whether denosumab is effective in postmenopausal Japanese women with osteoporosis, treated with AI. We prospectively evaluated the bone mineral density (BMD) in the lumbar spine and the bilateral femoral neck in 102 postmenopausal women with clinical hormone receptor-positive breast cancer, stages I-IIIA, during a postoperative period of 12 months...

Long-term anti-epileptic drug (AED) therapy compromises bone health. Though vitamin-D deficiency is proposed to be involved, it alone is not held responsible. This accounts for investigating other mechanisms in bone accrual. Recent studies have shown modulation of inhibitors of wnt pathway, sclerostin and dickkopf-1 (DKK-1), in glucocorticoids-induced osteoporosis. We investigated whether AED monotherapy modulates wnt inhibitors in Indian women with epilepsy. Women of age > 20-40 years with the diagnosis of epilepsy and receiving AEDs (carbamazepine, valproate and levetiracetam) for at least a year were enrolled...

BACKGROUND: The remarkable progress in the treatment of childhood acute lymphoblastic leukemia (cALL) has led to a survival rate reaching 90%. This success story is unfortunately linked to increased risk of impaired skeletal mass accumulation during childhood and adolescence, predisposing the patients to osteoporosis and pathological fractures at adulthood. OBJECTIVE: This study aims at characterizing the vitamin D status and bone health biomarkers in a well-characterized cohort of cALL survivors...

PURPOSE: The most common adverse reaction to zoledronic acid (ZOL) infusion is the acutephase reaction (APR), characterized by transient, usually mild, flu-like symptoms. Previous treatment with oral aminobisphosphonates (BPs) was reported as an independent protective factor for APR, and an association between APR and 25-hydroxyvitamin D (25[OH]D) levels in BP-naïve patients treated with ZOL was identified. The aim of our study was to confirm this association and to see if the association was different in patients previously treated with oral BPs compared with BP-naïve patients, and to investigate the role of 25(OH)D for the time of APR onset...

This study investigated whether or not vitamin D and calcium supplementation affected bone metabolism and bone mineral density (BMD) over a period of four years of denosumab therapy in patients with primary osteoporosis. Patients were divided into a denosumab monotherapy group (22 cases) or a denosumab plus vitamin D and calcium supplementation group (combination group, 21 cases). We measured serum bone alkaline phosphatase (BAP), tartrate-resistant acid phosphatase (TRACP)-5b, urinary N-terminal telopeptide of type-I collagen (NTX), and BMD of the lumbar 1-4 vertebrae (L-BMD) and bilateral hips (H-BMD) at baseline and at 12, 24, 36, and 48 months of treatment...

Osteoporosis is a frequent complication in patients with chronic liver disease, especially in end-stages and in chronic cholestasis, in addition to nonalcoholic fatty liver disease, hemochromatosis and alcoholism. Mechanisms underlying osteoporosis are poorly understood, but osteoporosis mainly results from low bone formation. In this setting, sclerostin, a key regulator of the Wnt/ß-catenin signalling pathway which regulates bone formation, in addition to the effects of the retained substances of cholestasis such as bilirubin and bile acids on osteoblastic cells, may influence the decreased bone formation in chronic cholestasis...

Surgical treatment of multiple vertebral fractures in patients with glucocorticoid-induced osteoporosis is difficult because of a high rate of secondary fracture postoperatively. A case is described in which initial treatment with teriparatide to improve osteoporosis followed by treatment of kyphosis with correction fusion achieved a favorable outcome. INTRODUCTION: Secondary fracture frequently occurs after treatment of vertebral fracture with vertebroplasty and balloon kyphoplasty in patients with glucocorticoid-induced osteoporosis, but effective treatment of multiple vertebral fractures has rarely been reported...
