Alterations in PTH circadian rhythm and PTH target-organ sensitivity exist in adult GH-deficient (AGHD) patients and may underlie the pathogenesis of AGHD-related osteoporosis. GH replacement (GHR) results in increased bone mineral density, but its benefit in AGHD patients over 60 yr old has been debated. To examine the effect of ...

BACKGROUND: Data on the incidence of bone marrow (BM) involvement in early-stage diffuse large B-cell lymphoma (DLBCL) are lacking. Although BM biopsy is a safe procedure, it is often poorly tolerated. This analysis aims to assess the incidence of BM involvement and to identify parameters predicting BM involvement in early-stage ...

Reflex sympathetic dystrophy (RSD) is a relative common sequel after hemiplegia. The diagnosis of RSD in hemiplegic patients presents difficult clinical problems, as the symptoms and signs of RSD are not specific and RSD may be due to reasons other than hemiplegia. Bone scintigraphy has been routinely used for the ...

The matricellular protein SPARC (secreted protein acidic and rich in cysteine)/osteonectin was determined in patients with multiple myeloma and related disease to assess the hypothesized role of SPARC as a possible marker of tumor burden and disease progression. Soluble SPARC was measured by competitive enzyme-linked immunosorbent assay (ELISA) in plasma ...

Acute myeloid leukemia (AML) is a clonal disorder characterized by abnormal proliferation of myeloid cell precursors. Research has mainly focused on the cellular events, but the bone marrow matrix has attracted minor interest. In this study bone marrow biopsies were obtained from 35 newly diagnosed AML patients. The bone marrows ...

Bone turnover is regulated by local concentrations of cytokines such as osteoprotegerin (OPG) and receptor activator of nuclear factor kappaB ligand (RANKL). It is not known whether these cytokines can predict renal osteodystrophy in peritoneal dialysis (PD) patients. We measured serum levels of OPG, RANKL, intact parathyroid hormone (iPTH), calcium, ...

The incidence of myelofibrosis (MF) among the three major Philadelphia chromosome-negative chronic myeloproliferative disorders, i.e. essential thrombocythaemia (ET), polycythaemia vera (PV) and chronic idiopathic myelofibrosis (CIMF), is not well documented since the diagnostic criteria have recently been redefined by the WHO. Therefore we performed a retrospective analysis of follow-up biopsies ...

Multiple myeloma is characterized by accelerated production of the proteolytic enzyme matrix metalloproteinase (MMP)-9. We hypothesized that myeloma-produced MMP-9 may influence the rate of bone turnover in a paracrine manner. Thus, we examined the correlations of MMP-9 levels, disease severity, and bone turnover rate as evaluated by markers of bone ...

Hyperparathyroidism contributes significantly to decreased bone mineral density (BMD) in end-stage renal disease patients, but this negative influence is not homogeneous throughout the skeleton. We studied the BMD by dual-energy X-ray absorptiometry on total body and on different regions of the skeleton in 42 patients with severe hyperparathyroidism on hemodialysis. ...

Osteoporosis is a common finding following chronic obstructive pulmonary disease (COPD), but there are few reports on the relationship between bone mineral density (BMD) and the syndrome types described in traditional Chinese medicine (TCM) in patients with COPD. A cross-sectional medical survey was used in this study. Twenty-six male patients ...

Two patients with a highly destructive histologic nondysplastic squamous epithelial lesion of the temporal bone are described. Both tumors were characterized by the production of copious amounts of keratin material which progressively extended in the temporal bone, surrounding bony structures, soft tissue and intracranially, with concomitant functional disorders. Only small ...

Inosine monophosphate dehydrogenase (IMPDH) inhibitors have been used to induce leukemia blast cell differentiation but have not been tested in multiple myeloma for activity. Currently, available IMPDH inhibitor, mycophenolate mofetil (MMF), which is known as an immunosuppressant, was shown to induce apoptosis in myeloma cell lines. On the basis of ...

Chronic kidney disease (CKD) leads to reduced bone mineral density (BMD) in pre-dialysis and dialysis patients. A few studies have used dual-energy x-ray absorptiometry (DEXA) to assess BMD in pre-dialysis CKD patients and have shown low BMD to be highly prevalent. Until now there have been no studies reporting the ...

Osteoprotegerin (OPG) is a potent antiresorptive molecule that binds NF-kappaB ligand, the final effector for osteoclastogenesis. OPG production is regulated by a number of cytokines and hormones. Osteopontin (OPN) is a secreted adhesive glycoprotein involved in tumour angiogenesis, and also a non-collagenous protein involved in bone turnover. OPN serum value ...

Estrogen deficiency and pulmonary diseases are associated with bone mineral density (BMD) loss. Lymphangioleiomyomatosis (LAM), a disorder affecting women that is characterized by cystic lung lesions, is frequently treated with antiestrogen therapy, i.e., progesterone and/or oophorectomy. Therefore, we evaluated BMD yearly in 211 LAM patients to determine the prevalence of ...

We hypothesized that in patients with chronic obstructive pulmonary disease, loss of fat-free mass (FFM) and loss of bone mineral density (BMD) were related to (1) each other and may be clinically inapparent, (2) urinary markers of cellular and bone collagen protein breakdown, and (3) severity of lung disease. Eight-one ...

Low bone mineral density (BMD) is a frequent, often persistent complication in patients with major depressive disorder (MDD) and anorexia nervosa (AN) that increases the risk of pathologic fractures. The pathogenetic process underlying osteopenia in MDD and AN is still unclear, although several factors, including a dysbalance of cytokines, are ...

BACKGROUND: Basic fibroblast growth factor (bFGF) is one of main regulators of hematopoiesis, including megakaryopoiesis. The main bone marrow finding of patients with idiopathic thrombocytopenic purpura (ITP) is increased megakaryopoiesis. The purposes of this study were to evaluate the change in the production of bFGF and its expression pattern in ...

Hypovitaminosis D is common in patients with peripheral arterial disease (PAD). Subsequent secondary hyperparathyroidism and osteomalacia contribute to bone pain and myalgias, and so aggravate clinical symptoms of claudication. We evaluated 95 out of 297 patients with angiographically confirmed PAD stages II (pain in the calves and/or thighs only during ...

A novel oncogenic mutation (FIP1L1-PDGFRA), which results in a constitutively activated platelet-derived growth factor receptor-alpha (PDGFRA), has been invariably associated with a primary eosinophilic disorder. The current study examines both the prevalence and the associated clinicopathologic features of this mutation in a cohort of 89 adult patients presenting with an ...

Fetomaternal microchimerism has been demonstrated, and immunologic tolerance to unshared HLA antigens between mother and offspring may be suggested. We used T-cell-repleted bone marrow transplantation (BMT) from their HLA-haploidentical mothers to treat 6 patients with fatal nonmalignant diseases. The number of mismatched HLA loci in the graft-versus-host disease (GVHD) direction ...

BACKGROUND: Low back pain (LBP) is very common in the general population. Most patients with LBP will receive an X-ray examination on lumbar spine; however, the results are likely to show a negative finding or degenerative joint disease, which are not truly pathological factors. Among various imaging diagnostic tools for ...

BACKGROUND: In chronic renal failure leptin levels are elevated and BMD decreased, however, so far data about correlations between leptin and BMD in dialyzed patients are scarce. It has been suggested that leptin is a predictor of BMD in postmenopausal women. We examined the relationships between leptinemia, BMD and bone ...
