Chronic elevated hemoglobin levels

H Matthew Lehrer, Susan K Dubois, Julie Maslowsky, Mark L Laudenslager, Mary A Steinhardt
BACKGROUND: African Americans have higher diabetes prevalence compared to Whites. They also have elevated cortisol levels - indicating possible HPA axis dysregulation - which may raise blood glucose as part of the biological response to physiological and psychosocial stress. Little is known about chronic cortisol levels in African Americans, and even less about the role of chronically elevated cortisol in type 2 diabetes development in this racial group. PURPOSE: We used analysis of cortisol in hair to examine associations of long-term (∼3months) cortisol levels with glycated hemoglobin (HbA1c) in a group of African American adults...

BACKGROUND: Iron supplementation is crucial for the treatment of anemia of chronic kidney disease (CKD). Although intravenous (IV) iron is preferred for patients with CKD receiving dialysis (CKD stage 5D), the method of iron replacement for patients with CKD stages 3 to 5 is controversial. STUDY DESIGN: Systematic review and meta-analysis. A search was performed until October 2015 of MEDLINE, Cochrane Library, conference proceedings in nephrology, and reference lists of included trials...

BACKGROUND: Proprotein convertase subtilisin/kexin type 9 (PCSK9) is involved in cholesterol homeostasis, inflammation, and oxidative stress. This study investigated the association of plasma PCSK9 levels with the presence and severity of peripheral artery disease (PAD) and with parameters of endothelial homeostasis. METHODS AND RESULTS: A post hoc analysis of 2 randomized trials (115 patients, 44 with PAD and 71 without atherosclerotic disease) was conducted. Patients with PAD had significantly higher plasma PCSK9 levels than those without (471...

AIMS: In patients with chronic kidney disease (CKD), severe anemia is associated with increased cardiovascular risk. Although elevating hemoglobin (Hb) and hematocrit (Hct) levels with erythropoiesis-stimulating agents (ESA) improves patients' quality of life, normalization of Hb does not reduce cardiovascular risk and the reason remains unclear. MAIN METHODS: We measured the effect of acute isovolumic changes in Hct from 37±5 to 50±2% (mean±SD) on arterial blood pressure (BP), cardiac output (CO), and carotid and renal blood flow (BF), (1) in control rats and (2) after acute blockade of the nitric oxide (NO) pathway by l-NAME...

BACKGROUND: End stage renal disease (ESRD) is a debilitating disease that not only impacts quality of life, but also increases the risk of cardiovascular disease, stroke, and overall mortality. By improving our understanding of the molecular patterns seen in progression of chronic renal disease (CRD), we may be able to slow down and possibly even prevent progression renal failure. The vascular endothelial growth factor (VEGF) has been implicated as a major contributor to CRD disease progression, thus our aim was to profile the VEGF levels in patients with ESRD and to determine the effects of the erythropoietin stimulating agents (ESAs)...

Acute kidney injury (AKI) after cardiac surgery is a common and serious complication. Although lower than normal serum bicarbonate levels are known to be associated with consecutive renal function deterioration in patients with chronic kidney injury, it is not well-known whether preoperative low serum bicarbonate levels are associated with the development of AKI in patients who undergo cardiac surgery. Therefore, the clinical implication of preoperative serum bicarbonate levels on AKI occurrence after cardiac surgery was investigated...

Disturbances of calcium homeostasis might be involved in the pathogenesis of the metabolic derangements associated with uraemia. Indices of glucose and lipoprotein metabolism as well as blood pressure were measured in nine patients with chronic renal failure who were on regular hemodialysis. Seven of them thereafter received alphacal-cidol (a synthetic analogue to active vitamin D) intravenously for three months. Prior to therapy the patients had, compared with age and sex matched controls, impaired glucose tolerance, hyperlipoproteinemia and raised blood pressure...

Chronic mountain sickness (CMS) results from chronic hypoxia. It is unclear why certain highlanders develop CMS. We hypothesized that modest increases in fetal hemoglobin (HbF) are associated with lower CMS severity. In this cross-sectional study, we found that HbF levels were normal (median = 0.4%) in all 153 adult Andean natives in Cerro de Pasco, Peru. Compared with healthy adults, the borderline elevated hemoglobin group frequently had symptoms (headaches, tinnitus, cyanosis, dilatation of veins) of CMS...

BACKGROUND: Chronic metformin treatment was found to reduce elevated thyrotropin levels. Amiodarone treatment is associated with a range of effects in thyroid function from mild derangements to overt thyroid dysfunction. No previous study has investigated the effect of metformin on hypothalamic-pituitary-thyroid axis activity in patients with amiodarone-induced hypothyroidism. METHODS: The study included three age-, sex- and weight-matched groups of amiodarone-treated patients with type 2 diabetes: patients with treated overt hypothyroidism (group I, n=15), patients with untreated subclinical hypothyroidism (group II, n=15), and subjects without thyroid disorders (group III, n=18)...

BACKGROUND AND AIMS: Malnutrition is associated with poor clinical outcomes. Whether there is a causal relationship or it merely mirrors a severe patient condition remains unclear. We examined the association of malnutrition with biomarkers characteristic of different pathophysiological states to better understand the underlying etiological mechanisms. METHODS: We prospectively followed consecutive adult medical inpatients. Multivariable regression models were used to investigate the associations between malnutrition - as assessed using the Nutritional Risk Screening (NRS 2002) - and biomarkers linked to inflammation, stress, renal dysfunction, nutritional status and hematologic function...

OBJECTIVES: Anemia is the most common hematological alteration in patients with Crohn's disease, and is frequently related to intestinal inflammatory activity. Its cause is multifactorial and mostly associated with absolute iron deficiency (iron deficiency anemia) and/or functional iron deficiency (inflammation anemia or anemia of chronic disease). It may also be identified through other causes, such as folic acid or vitamin B12 deficiency and secondary to adverse effects from medications (salicylic derivatives and immunosuppressive drugs)...

The kidney is very susceptible to hypoxic injury. Calcineurin inhibitors (CNIs) induce vasoconstriction and might reduce renal tissue oxygenation. We aimed to investigate if the synergistic deleterious effects of CNI-treatment and hypoxia of high altitude living might accelerate the development of arteriolar hyalinosis in kidney allografts. We stratified all patients who received a kidney graft from 2000 to 2010 in our centre (n = 477) in three groups according to the residential elevation (below 400, between 400 to 600 and above 600 m above sea level) and we retrospectively re-evaluated all transplant biopsies performed during follow-up, specifically looking at the degree of arteriolar hyalinosis, the hallmark of chronic CNI nephrotoxicity...

OBJECTIVE: To explore the effects of high-flux hemodialysis (HFHD) on fibroblast growth factor 23 (FGF-23) and micro-inflammatory state in end-stage renal diseases (ESRD) patients to understand the advantages of HFHD in reducing complications in ESRD patients. METHODS: A total of 60 subjects sheduled for hemodialysis at our hospital in 2012 were randomly divided into two groups of 3-month HFHD and 3-month low-flux hemodialysis (LFHD) (n = 30 each). The levels of serum factors, such as FGF-23, were observed before and after 3-month hemodialysis to evaluate the hemodialysis sufficiency of two groups and analyze the effects of FGF-23 related factors as well as different kinds of hemodialysis on microinflammatory state, biochemical indices and dialysis sufficiency...

Doxorubicin can cause life-threatening toxic effects in several organs, with cardiotoxicity being the major concern. Although a large number of animal models have been utilized to study doxorubicin toxicity, several restrictions limit their use. Since the Göttingen minipig is an accepted species for non-clinical safety assessment and translation to man, we aimed at exploring its use as a non-rodent animal model for safety assessment and regulatory toxicity studies using doxorubicin. Three groups of three males and three females adult Göttingen minipigs received 1...

BACKGROUND: Oral submucous fibrosis (OSMF) is a debilitating, potentially cancerous oral condition. Although areca nut is the most important causative agent, it is also considered that the disease is immunologically mediated. AIM OF THE STUDY: To establish that autoimmunity and nutritional deficiency play a role in the etiopathogenesis of OSMF. OBJECTIVES OF THE STUDY: To show that serum immunoglobulin markers (immunoglobulin-G [IgG], immunoglobulin-A [IgA]) and nutritional parameters such as total serum protein (TSP), Hemoglobin (Hb) play a role in causing OSMF and also to correlate serum, salivary IgG, IgA levels in OSMF patients...
