“…Among numerous drugs used for HPI-related diseases many are well known to contribute to OP/OFs. In regard to OP, these include corticosteroids, antidepressants (especially, selective serotonin- and serotonin-norepinephrine reuptake inhibitors), glitazones, opioids, benzodiazepines, antipsychotics, antiparkinsonian drugs, antiepileptics, PPIs, H2RA, thyroxine, furosemide, aromatase inhibitors, gonadotropin releasing hormone (GnRH) agonists, whereas hormone replacement therapy with estrogen, thiazides, angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs), spironolactone, beta-blockers, statins, antihistamines, metformin, sulphonylureas, glucagon-like peptide-1 receptor agonists (liraglutide) and nitrates have shown an osteoprotective effect [ 316 , 521 , 522 , 523 , 524 , 525 , 526 , 527 , 528 , 529 , 530 , 531 , 532 , 533 , 534 , 535 , 536 , 537 , 538 , 539 , 540 , 541 , 542 , 543 , 544 , 545 , 546 , 547 , 548 , 549 , 550 , 551 , 552 , 553 , 554 ].…”

“…Some agents have shown divergent effects on bone and skeletal muscles. For example, thiazolidinediones demonstrate detrimental effect on the skeleton and increase fracture risk [ 545 , 599 , 600 , 601 , 602 , 603 , 604 ] but a beneficial effect on muscle atrophy [ 605 ]; other anti-diabetic drugs (sulfonylureas, metformin and possible incretin mimetics) have a neutral or a positive/protective effect on bone health, but they may increase propensity for falls through hypoglycemia (insulin and sulfonylureas) [ 601 , 603 , 604 , 606 ]. When analyzing the complex relationships between OFs and drugs used it should also be taken into account that many medications (corticosteroids, sulfonamides, urea derivatives, vitamin K antagonists, cardiac glycosides, loop diuretics, potassium-sparing diuretics, ACE inhibitors, serotonin reuptake inhibitors, calcium-channel blockers and antiepileptic drugs) may affect the vitamin D status and calcium homeostasis [ 607 , 608 , 609 , 610 , 611 ].…”

Osteoporosis (OP) and osteoporotic fractures (OFs) are common multifactorial and heterogenic disorders of increasing incidence. Helicobacter pylori (H.p.) colonizes the stomach approximately in half of the world’s population, causes gastroduodenal diseases and is prevalent in numerous extra-digestive diseases known to be associated with OP/OF. The studies regarding relationship between H.p. infection (HPI) and OP/OFs are inconsistent. The current review summarizes the relevant literature on the potential role of HPI in OP, falls and OFs and highlights the reasons for controversies in the publications. In the first section, after a brief overview of HPI biological features, we analyze the studies evaluating the association of HPI and bone status. The second part includes data on the prevalence of OP/OFs in HPI-induced gastroduodenal diseases (peptic ulcer, chronic/atrophic gastritis and cancer) and the effects of acid-suppressive drugs. In the next section, we discuss the possible contribution of HPI-associated extra-digestive diseases and medications to OP/OF, focusing on conditions affecting both bone homeostasis and predisposing to falls. In the last section, we describe clinical implications of accumulated data on HPI as a co-factor of OP/OF and present a feasible five-step algorithm for OP/OF risk assessment and management in regard to HPI, emphasizing the importance of an integrative (but differentiated) holistic approach. Increased awareness about the consequences of HPI linked to OP/OF can aid early detection and management. Further research on the HPI–OP/OF relationship is needed to close current knowledge gaps and improve clinical management of both OP/OF and HPI-related disorders.

“…Patients with type 2 diabetes mellitus (T2DM) are at increased risk for bone fracture independent of bone mineral density (BMD). 1,2 Recent studies focused on bone structure quality have shown that trabecular and cortical bone microstructure are more fragile in patients with T2DM. [3][4][5][6] These findings have led to increased interest in the mechanisms of T2DM-induced bone microstructure damage, with the goal of developing new treatments for T2DM-induced osteoporosis.…”

Purpose: Osteocyte network structure correlates with bone material quality. This network is profoundly altered in diabetic mice; however, the underlying mechanisms are unknown. The gap junction protein connexin 43 (Cx43) is necessary for normal osteocyte function and osteocyte network formation. Here, we evaluated Cx43 expression in patients with diabetes, the effect of high glucose on Cx43 expression, and the function of Cx43 gap junctions and hemichannels in osteocyte-like MLO-Y4 (MLO-Y4) cells. Patients and Methods: Human cortical bone samples were obtained from patients with or without type II diabetes mellitus (T2DM) who underwent arthroplasty surgery to treat osteoporosis-induced femoral neck fracture. Cx43 expression was quantified in human cortical bone samples from both groups of patients and MLO-Y4 cells. The functions of Cx43 gap junctions and hemichannels in MLO-Y4 cells were evaluated using dye transfer and dye uptake assays, respectively. Furthermore, we evaluated levels of membrane Cx43 (mCx43), the functional form, and p38MAPK/ERK1/2 signaling, which is involved in mCx43 internalization, to characterize the mechanism of decreased Cx43 expression and gap junctions and hemichannels function. Results: Osteocyte Cx43 expression was decreased in femoral neck cortical bone samples of patients with T2DM patients compared with the non-diabetic control group. In addition, Cx43 expression was decreased in MLO-Y4 cells treated with high glucose. The functions of Cx43 gap junctions and hemichannels were inhibited in MLO-Y4 cells treated with high glucose. mCx43 expression was decreased in response to activation of p38-MAPK/ERK signaling. Inhibition of the p38-MAPK/ERK pathway partially reversed the decreases in Cx43 hemichannels and gap-junctions function. Conclusion: High glucose dampened Cx43 gap junction and hemichannel function in MLO-Y4 cells by activating the p38MAPK/ERK pathway leading to subsequent mCx43 internalization.

“…Many studies have found that patients with hepatic failure have an increased risk of osteoporosis; the pathogenesis of bone loss and osteoporosis in patients with hepatic failure is complex and multifactorial [7,9]. A study reported that low levels of insulin-like growth factor 1 in patients with advanced liver cirrhosis may aggravate bone remodelling and maintenance of bone mass in elderly patients, causing fragility fractures [10,11]. In addition, patients with HE have demonstrated poor cognitive function and are often a icted by psychiatric illnesses, which may increase the risk of sustaining an injury due to a fall [5].…”

Background: Osteoporotic hip fracture is a common general health problem with significant impact of human life because it debilitates the patients and largely decrease their life quality. Early prevention of the fracture is essential in the recent decades by finding out the related risk factors as reference of further intervention, especially for the vulnerable patient group with comorbidities. Hepatic encephalopathy, a major complication of liver cirrhosis, may increase the rate of falling down and weaken the bone quality. This paper is aimed to finding out the correlation between hepatic encephalopathy and osteoporotic hip fracture in the aged patients from our national population.Methods: This retrospective cohort study used data from Taiwan’s National Health Insurance Research Database between 2000 and 2012. We focus on people who were older than 50 years old, using hepatic encephalopathy as compare grouping accordance, and finding the influence of the other common chronic illness. Patients with and without hepatic encephalopathy were matched at a ratio of 1:4 for age, sex, and index year. The incidence and hazard ratios of comorbidities related to aging and poor lifestyle were calculated using Cox proportional hazard regression modelsResults: The average age of the enrolled patients was approximately 66.5 years. The incidence ratio of hip fracture in HE group was 68/2496 (2.7 %), which was significantly higher than that in non-HE group as 98/9984 (0.98 %). Patients with hepatic encephalopathy were 2.15-times more likely to develop osteoporotic hip fractures than patients without hepatic encephalopathy in the whole group and the risk ratio was also significantly higher in female and older patients. The results were also similar in the comorbidity subgroups of hypertension, diabetes mellitus, hyperlipidemia, senile cataract, gastric ulcer and depression.Conclusions: Hepatic encephalopathy is significantly associated with an increased risk of osteoporotic hip fractures and the significance was not affected by the comorbidities in people aged more than 50 years old from the results of our study, and the risk cumulated steadily through time goes by. These patients would benefit from controlling their hepatic encephalopathy and reducing the subsequent osteoporotic hip fractures.
