Individualizing HbA1c targets for patients with diabetes: impact of an automated algorithm within a primary care network.

AIMS: To develop glycaemic goal individualization algorithms and assess potential impact on a healthcare system and different segments of the population with diabetes. METHODS: A cross-sectional observational study of patients with diabetes in a primary care network age > 18 years with an HbA1c measured between 1 January and 31 December 2011. We applied diabetes guidelines to create targeted algorithms 1 and 2, which assigned HbA1c goals based on age, duration of diabetes (< 15 years or < 10 years), diabetes complications and Charlson co-morbidity score (< 6 or < 4) [targeted algorithm 2 was designed to assign more patients a goal < 64 mmol/mol (8.0%) than targeted algorithm 1]. Each patient's HbA1c was compared with these targeted goals and to the 'standard' goal < 53 mmol/mol (7.0%). Agreement was tested using McNemar's test. RESULTS: Overall, 55.7% of 12 199 patients would be considered controlled under the 'standard' approach, 61.2% under targeted algorithm 1 and 67.5% under targeted algorithm 2. Targeted algorithm 1 reclassified 1213 (23.6%) patients considered uncontrolled under the standard approach to controlled, P < 0.001. Targeted algorithm 2 reclassified 1844 (35.2%) patients, P < 0.001. Compared with those controlled under the standard goal, there was no significant difference in the proportion of those controlled using targeted goals who had Medicaid, had less than a high school diploma or received primary care in a federally qualified health centre. CONCLUSIONS: Two automated targeted algorithms would reclassify one quarter to one third of patients from uncontrolled to controlled within a primary care network without differentially affecting vulnerable patient subgroups.

Intensification of diabetes medication and risk for 30-day readmission.

AIM: To examine the association of in-hospital diabetes regimen intensification with subsequent 30-day risk for unplanned readmission/emergency department admission. METHODS: We retrospectively studied 1949 adults with Type 2 diabetes receiving primary care within an academic health network admitted to the hospital between January 2007 and December 2009. Glucose therapy intensification was defined as new start of insulin or oral hypoglycaemic agents, or addition of prandial insulin or insulin mixtures. The association of glucose therapy intensification with subsequent 30-day risk for unplanned readmission/emergency department admission was examined, with focus on medicine service patients with poorly controlled glycaemia (baseline HbA(1c) ≥ 64 mmol/mol). RESULTS: One in six patients (324/1949, 17%) had early readmission/emergency department admission. Compared with patients without early readmission, readmitted patients were more often male (58 vs. 52%, P = 0.03), had higher Charlson co-morbidity score [mean (sd) 3.0 (2.0) vs. 2.8 (1.8), P = 0.02], longer length of stay [5 (4.4) vs. 3.9 (3.3) days, P < 0.01] and were more often discharged home with nursing services (38 vs. 32%, P = 0.03). Overall, glucose therapy intensification was not associated with early hospital readmission/emergency department admission (odds ratio 0.94, 95% CI 0.64-1.37, P = 0.74). However, among medicine service patients with baseline HbA(1c) ≥ 64 mmol/mol (8%), glucose therapy intensification was associated with a significantly decreased early readmission risk (adjusted odds ratio 0.33, 95% CI 0.12-0.88, P = 0.03) and lower post-discharge HbA(1c) {mean decrease (sd): 20 (26) mmol/mol [1.8 (2.4)%] vs. 7 (15) mmol/mol [0.6 (1.4)%], P < 0.01}. CONCLUSIONS: Diabetes medical regimen intensification during hospitalization was not associated with early readmission. Among patients with elevated HbA(1c) , glucose therapy intensification was associated with a decreased 30-day readmission/emergency department admission risk and lower outpatient HbA(1c) levels. Our findings support the safety and durable impact of diabetes regimen optimization during hospital admission.

Canagliflozin, a novel inhibitor of sodium glucose co-transporter 2, dose dependently reduces calculated renal threshold for glucose excretion and increases urinary glucose excretion in healthy subjects.

Canagliflozin, a potent, selective sodium glucose co-transporter 2 inhibitor in development for treatment of type 2 diabetes, lowers plasma glucose (PG) by lowering the renal threshold for glucose (RT(G) ) and increasing urinary glucose excretion (UGE). An ascending single oral-dose phase 1 study investigated safety, tolerability and pharmacodynamics of canagliflozin in healthy men (N = 63) randomized to receive canagliflozin (n = 48) or placebo (n = 15). Canagliflozin (10, 30, 100, 200, 400, 600 or 800 mg q.d. or 400 mg b.i.d.) was administered to eight cohorts (six subjects/cohort: canagliflozin; two subjects/cohort: placebo). Dose dependently, canagliflozin decreased calculated 24-h mean RT(G) with maximal reduction to approximately 60 mg/dl, and increased mean 24-h UGE. At doses >200 mg administered before breakfast, canagliflozin reduced postprandial PG and serum insulin excursions at that meal. Canagliflozin was generally well tolerated; most adverse events were mild and no hypoglycaemia was reported. These results support further study of canagliflozin.

Cognitive Behavioral Therapy for Adherence and Depression (CBT-AD) in Type 2 Diabetes.

Depression is one of the most common psychological problems among individuals diabetes, and it is associated with worse treatment adherence and clinical outcomes. As part of a program of treatment research aimed at integrating interventions for depression and treatment nonadherence, five depressed patients with suboptimally controlled type 2 diabetes were treated with 10-12 sessions of individual cognitive behavioral therapy for adherence and depression (CBT-AD) in a case-series design. The intervention was delivered in a hospital setting by a collaborative team consisting of a psychologist, a nurse educator, and a dietitian. Post-treatment, all participants demonstrated a decrease in depression severity and demonstrated improvements in diabetes self-care. Four of the five demonstrated improved glycemic control. These preliminary results provide evidence for the acceptability, feasibility, and potential utility of CBT-AD for patients with type 2 diabetes and depression.

Symptoms of depression prospectively predict poorer self-care in patients with Type 2 diabetes.

AIMS: To examine prospectively the association of depression symptoms with subsequent self-care and medication adherence in patients with Type 2 diabetes mellitus. METHODS: Two hundred and eight primary care patients with Type 2 diabetes completed the Harvard Department of Psychiatry/National Depression Screening Day Scale (HANDS) and the Summary of Diabetes Self-Care Activities (SDSCA) at baseline and at follow-up, an average of 9 months later. They also self-reported medication adherence at baseline and at a follow-up. RESULTS: Baseline HANDS scores ranged from 0 to 27, with a mean score of 5.15 +/- 4.99. In separate linear regression models that adjusted for baseline self-care, patients with higher levels of depressive symptoms at baseline reported significantly lower adherence to general diet recommendations and specific recommendations for consumption of fruits and vegetables and spacing of carbohydrates; less exercise; and poorer foot care at follow-up (beta ranging from -0.12 to -0.23; P < 0.05). Similarly, each one-point increase in baseline HANDS score was associated with a 1.08-fold increase in the odds of non-adherence to prescribed medication at follow-up (95% confidence interval 1.001, 1.158, P = 0.047). Increases in depression scores over time also predicted poorer adherence to aspects of diet and exercise. CONCLUSIONS: Depressive symptoms predict subsequent non-adherence to important aspects of self-care in patients with Type 2 diabetes, even after controlling for baseline self-care. Although the relationship between symptoms of depression and poorer diabetes self-care is consistent, it is not large, and interventions may need to address depression and self-care skills simultaneously in order to maximize effects on diabetes outcomes.

Association of diabetes-related emotional distress with diabetes treatment in primary care patients with Type 2 diabetes.

AIMS: To characterize the determinants of diabetes-related emotional distress by treatment modality (diet only, oral medication only, or insulin). METHODS: A total of 815 primary care patients with Type 2 diabetes completed the Problem Areas in Diabetes (PAID) Scale and other questions. We linked survey data to a diabetes clinical research database and used linear regression models to assess the associations of treatment with PAID score. RESULTS: PAID scores were significantly higher among insulin-treated (24.6) compared with oral-treated (17.8, P < 0.001) or diet-treated patients (14.7, P < 0.001), but not different between oral- vs. diet-treated patients (P = 0.2). Group scores remained similar, but the statistical significance of their differences was reduced and ultimately eliminated after sequential adjustment for diabetes severity, HbA(1c), body mass index, regimen adherence, and self-blood-glucose monitoring. Insulin-treated patients reported significantly higher distress than oral- or diet-treated patients on 16 of 20 PAID items. 'Worrying about the future' and 'guilt/anxiety when ... off track with diabetes' were the top two serious problems (PAID >or= 5) in all treatment groups. Not accepting diabetes diagnosis was a top concern for oral- and diet-treated patients, and unclear management goals distressed diet-treated patients. CONCLUSIONS: Primary care patients treated with insulin reported higher diabetes-related emotional distress compared with oral- or diet-treated patients. Greater distress was largely explained by greater disease severity and self-care burdens. To improve diabetes-specific quality of life, clinicians should address patients' sense of worry and guilt, uncertain acceptance of diabetes diagnosis, and unclear treatment goals.

Correlates of health-related quality of life in type 2 diabetes.

AIMS/HYPOTHESIS: We assessed the impact of medical comorbidities, depression, and treatment intensity on quality of life in a large primary care cohort of patients with type 2 diabetes. METHODS: We used the Health Utilities Index-III, an instrument that measures health-related quality of life based on community preferences in units of health utility (scaled from 0=death to 1.0=perfect health), in 909 primary care patients with type 2 diabetes. Demographic and clinical correlates of health-related quality of life were assessed. RESULTS: The median health utility score for this population was 0.70 (interquartile range 0.39-0.88). In univariate analyses, older age, female sex, low socioeconomic status, cardiovascular disease, microvascular complications, congestive heart failure, peripheral vascular disease, chronic lung disease, depression, insulin use and number of medications correlated with decreased quality of life, while obesity, hypertension and hypercholesterolaemia did not. In multiple regression analyses, microvascular complications, heart failure and depression were most strongly related to decreased health-related quality of life, independently of duration of diabetes; in these models, diabetes patients with depression had a utility of 0.59, while patients without symptomatic comorbidities did not have a significantly reduced quality of life. Treatment intensity remained a significant negative correlate of quality of life in multivariable models. CONCLUSIONS/INTERPRETATION: Patients with type 2 diabetes have a substantially decreased quality of life in association with symptomatic complications. The data suggest that treatment of depression and prevention of complications have the greatest potential to improve health-related quality of life in type 2 diabetes.

Circulating adiponectin concentrations in patients with congestive heart failure.

OBJECTIVES: To determine concentrations of adiponectin and its predictive value on outcome in a cohort of patients with congestive heart failure (CHF). METHODS: Serum and clinical data were obtained for outpatients with clinically controlled CHF (n = 175). Serum concentrations of adiponectin, C reactive protein, N-terminal pro-brain natriuretic peptide (NT-proBNP), interleukin (IL) -1beta, IL-6, IL-8, IL-10, IL-12, tumour necrosis factor alpha and CD-40 ligand were determined. The association of adiponectin with the clinical severity of CHF was sought as well as the predictive value of this adipokine on mortality, CHF hospitalisations or the occurrence of each of these end points. RESULTS: Concentrations of adiponectin were significantly increased in patients with CHF. Patients with higher New York Heart Association class had significantly higher serum concentrations of adiponectin. Adiponectin serum concentrations were lower in patients with diabetes and CHF as well as in patients with ischaemic cardiomyopathy. Serum adiponectin concentration was positively associated with age and NT-proBNP but was negatively correlated with C reactive protein concentrations. Serum adiponectin above the 75th centile was found to be an independent predictor of total mortality, CHF hospitalisations or a composite of these end points over a two-year prospective follow up. CONCLUSION: Adiponectin is increased in CHF patients and predicts mortality and morbidity.

Pharmacokinetics, safety, and efficacy of posaconazole in patients with persistent febrile neutropenia or refractory invasive fungal infection.

The pharmacokinetic profiles, safety, and efficacies of different dosing schedules of posaconazole oral suspension in patients with possible, probable, and proven refractory invasive fungal infection (rIFI) or febrile neutropenia (FN) were evaluated in a multicenter, open-label, parallel-group study. Sixty-six patients with FN and 32 patients with rIFI were randomly assigned to one of three posaconazole regimens: 200 mg four times a day (q.i.d.) for nine doses, followed by 400 mg twice a day (b.i.d.); 400 mg q.i.d. for nine doses, followed by 600 mg b.i.d.; or 800 mg b.i.d. for five doses, followed by 800 mg once a day (q.d.). Therapy was continued for up to 6 months in patients with rIFI or until neutrophil recovery occurred in patients with FN. The 400-mg-b.i.d. dose provided the highest overall mean exposure, with 135% (P = 0.0004) and 182% (P < 0.0001) greater exposure than the 600-mg-b.i.d. and 800-mg-q.d. doses, respectively. However, exposure in allogeneic bone marrow transplant (BMT) recipients (n = 12) was 52% lower than in non-BMT patients. Treatment-related adverse events (occurring in 24% of patients) were mostly gastrointestinal in nature. Twenty-four percent of patients had adverse events leading to premature discontinuation (none were treatment related). In efficacy-evaluable patients, successful clinical response was observed in 43% with rIFI (56% of patients receiving 400 mg b.i.d., 17% receiving 600 mg b.i.d., and 50% receiving 800 mg q.d.) and 77% with FN (74% receiving 400 mg b.i.d., 78% receiving 600 mg b.i.d., and 81% receiving 800 mg q.d.). Posaconazole is well tolerated and absorbed. Divided doses of 800 mg (400 mg b.i.d.) provide the greatest posaconazole exposure.

Correction of anemia in patients with congestive heart failure increases resting energy expenditure.

BACKGROUND & AIM: Congestive heart failure (CHF) and anemia were reported to affect resting energy expenditure (REE). The aim of this study was to evaluate the effect of the correction of anemia on REE in subjects with CHF. PATIENTS AND METHODS: Nine anemic patients with compensated CHF and CRF were studied before and after correction of anemia. REE was studied by an open circuit indirect calorimeter, body composition by dual-energy-X-ray absorption and total body and extracellular water by multi-frequency bioelectrical impedence. Four anemic and 5 non-anemic CHF patients who did not receive any new treatment served as controls. RESULTS: After the correction of their anemia patients tended to increase weight (P<0.06), but no significant changes were observed in body composition. Daily caloric intake increased significantly (P<0.02). Ejection fraction increased (P<0.05) and pulse rate decreased significantly (P<0.001). REE and REEPP were in the normal range before correction but increased significantly afterwards (1402+/-256 vs. 1496+/-206 kcal/d, and 101+/-9 vs. 109+/-8, P<0.023 and P<0.006, respectively). CONCLUSION: Correction of anemia in patients with CHF increases their REE. This can be related either to improved tissue oxygenation and/or to increased caloric intake.

Effect of posaconazole on cytochrome P450 enzymes: a randomized, open-label, two-way crossover study.

Posaconazole is an antifungal with a wide-spectrum of activity against common and emerging fungal pathogens. In this randomised, open-label, two-way crossover study, the potential for drug interactions with posaconazole via the cytochrome P450 (CYP450) enzyme pathway was evaluated. Thirteen subjects received posaconazole tablets (2 x 100 mg) once daily for 10 days or no treatment; following a 14-day washout period, subjects were crossed over to the alternate treatment. The inhibition spectra of posaconazole were examined using a cocktail of the following probe substrates: caffeine (CYP1A2), tolbutamide (CYP2C8/9), dextromethorphan (CYP2D6 and total CYP3A4), chlorzoxazone (CYP2E1), and midazolam (hepatic CYP3A4). Except for midazolam, which was intravenously infused on Day 10, the cocktail probes were administered simultaneously on Day 9 during both treatment periods. Blood and urine samples were collected at specified times to quantitate probe substrates and/or metabolites. Based on insignificant differences in mean probe ratios, posaconazole did not inhibit CYP1A2, 2C8/9, 2D6, or 2E1. However, the midazolam AUC((tf)) was higher in the posaconazole than no-treatment group (93.4 n gh/ml versus 51.4 ng h/ml, P<0.01), indicating inhibition of hepatic CYP3A4. Drug interactions mediated by various CYP450 are common with the currently available triazole antifungals, however these results suggest that posaconazole may have an improved and more narrow drug interaction profile (CYP3A4 only) compared with other triazoles.

The cardio renal anemia syndrome: correcting anemia in patients with resistant congestive heart failure can improve both cardiac and renal function and reduce hospitalizations.

Anemia (Hemoglobin of < 12 to 13 g/dl) is frequently encountered in patients with congestive heart failure (CHF). This anemia may be partly due to hemodilution, partly to the associated reduction in renal function, and partly to the use of ACE inhibitors and aspirin. However, there is evidence that CHF alone--through excessive cytokine production may also reduce the bone marrow and cause anemia. In several recent studies anemia has been found to be associated with a more severe degree of CHF, a higher rate of death, renal failure, hospitalization and evidence of malnutrition. In both uncontrolled and controlled studies correction of anemia with erythropoietin with or without the addition of i.v. iron has been attempted. The correction of anemia has been associated with a marked improvement in New York Heart Association (NYHA) functional cardiac class and Left Ventricular Ejection Fraction, a marked reduction in the need for hospitalization and high dose oral and i.v. diuretics, and an improvement in exercise capacity, peak exercise oxygen utilization and quality of life. The serum creatinine, which had been increasing steadily before treatment, stabilized with the correction of anemia. All this suggests that control of anemia in CHF could become a valuable addition to the therapeutic armamentarium of CHF and might also play a major role in the prevention of progressive renal failure.

Anemia in chronic kidney disease and congestive heart failure.

Anemia is seen in chronic kidney insufficiency (CKI), dialysis patients, congestive heart failure (CHF), and renal transplantation. Anemia can lead to progressive cardiac damage as well as progressive renal damage. It is not generally appreciated that CHF itself may be a very common contributor to both the production of anemia as well as to the progression of the renal failure. Correction of the anemia with erythropoietin and, as necessary, intravenous iron, may prevent the deterioration of both the heart and the kidneys. We suggest that there is a triangular relationship, a vicious circle, between CHF, CKI and anemia where each of these three can both cause and be caused by the other. We call this syndrome the cardio-renal anemia (CRA) syndrome. All physicians, especially cardiologists and internists who treat CKI and CHF, should be made aware of the dangers of anemia in CKI and CHF and should work with nephrologists to correct it.

The correction of anemia in severe resistant heart failure with erythropoietin and intravenous iron prevents the progression of both the heart and the renal failure and markedly reduces hospitalization.

Both Congestive Heart Failure (CHF) and Chronic Renal Failure (CRF) are increasing steadily in the community. We propose that there is a vicious circle established whereby CHF and CRF both cause anemia and the anemia then worsens both the CHF and CRF causing more anemia and so on. We call this the Cardio Renal Anemia (CRA) syndrome. By the combination of active treatment of the CHF and control of the anemia with subcutaneous erythropoietin and intravenous iron, the progression of both the CHF and the CRF can be slowed or stopped in most cases, the quality of life improved and the need for recurrent hospitalization reduced. This will involve cooperation between internists, cardiologists, and nephrologists to allow early and maximal therapy of both the CHF and the anemia.

Mechanical milling assisted by electrical discharge.

Mechanical milling is an effective technique for the preparation of fine metallic and ceramic powders and can also be used to drive a wide range of chemical reactions. Milling devices include planetary machines, attritors and vibrational mills; products include amorphous, nanocrystalline and quasicrystalline materials, supersaturated solid solutions, reduced minerals, high-surface-area catalysts and reactive chemicals. During milling, solid-solid, solid-liquid and solid-gas reactions are initiated through repeated deformation and fracture of powder particles. A separate materials synthesis and processing technique involves reacting a material in a gas atmosphere under an electrical discharge. Here we show that the application of low-current, high-voltage electrical impulses during milling can result in both faster reactions and new synthesis and processing routes. We demonstrate the effects of glow (cold) and spark (hot) discharge milling on particle fracture for brittle, low-conductivity materials and ductile metals. Glow discharge milling was found to promote solid-gas reactions whereas spark discharge milling promotes fast fracturing, recrystallization, mineral reduction and solid-solid reactions.

The plasma concentration and LDL-C relationship in patients receiving ezetimibe.

Ezetimibe is a novel selective inhibitor of intestinal cholesterol absorption, which has been shown to significantly decrease low-density lipoprotein cholesterol (LDL-C). In this article, the relationship between plasma ezetimibe concentrations and lowering of LDL-C is determined using Emax and regression models. Data from two phase II double-blind placebo-controlled studies (n = 232 and 177) were used in which daily doses of ezetimibe ranging from 0.25 to 10 mg were administered for 12 weeks. Ezetimibe concentrations correlated significantly with percentage change in LDL-C from baseline (%LDL-C). Reductions in %LDL-C of 10%, 15%, and 20% were achieved with concentrations in the ranges 0 to 2, 2 to 15, and > 15 ng/ml, respectively, as compared with placebo. To achieve > 15% reduction in LDL-C, patients need to maintain trough concentrations > 15 ng/ml, taking plasma concentrations as a surrogate for concentrations at the enterocyte. Based on the doses administered, the 10 mg dose had the highest likelihood of sustaining such concentrations, confirming that a daily 10 mg dose of ezetimibe is an optimal therapeutic dose in the treatment of hypercholesterolemia.

Predictors of costs of caring for elderly patients discharged with heart failure.

BACKGROUND: Investments in programs to improve outcomes and reduce readmissions for patients who survive hospitalization with heart failure will be economically most favorable for those who have the highest risk. Little information is available, however, to stratify the risk of these patients incurring costs after discharge. In this study, we sought to determine correlates of costs in a representative sample of patients with heart failure in the 6 months after discharge. METHODS: We reviewed medical records of 2181 patients aged > or = 65 years who were discharged alive from 18 Connecticut hospitals in 1994 and 1995 with a principal discharge diagnosis of heart failure. Outcomes 6 months after discharge, including all-cause readmission and cost, heart failure-related readmission and cost, and death, were obtained from the Medicare administrative database. A 2-stage sample selection model was used to identify the independent correlates of cost. Risk scores were calculated to identify subsets of patients at risk for generating high costs. RESULTS: On average, patients discharged with heart failure incurred costs of $2388 resulting from heart failure-related admissions and $7101 resulting from admissions from any cause during the 6 months after discharge. An average admission for heart failure cost $7174, whereas an admission resulting from any cause cost $8589. The multivariate models explained 7% of the variation in cost, although clinical characteristics such as recent heart failure admissions, kidney failure, and hypertension were significant independent correlates of increased cost. Older age and a history of stroke were independently associated with decreased cost. Patients without any of the risk factors associated with increased costs still incurred $1500 to $5000, on average, in the 6 months after discharge. CONCLUSIONS: Patients with heart failure generate substantial hospital costs in the 6 months after discharge. Given the emerging evidence for effective programs to reduce readmission, investments in interventions that produce even modest reductions in risk would be economically favorable.

A population pharmacokinetic model that describes multiple peaks due to enterohepatic recirculation of ezetimibe.

BACKGROUND: Ezetimibe, a selective inhibitor of intestinal cholesterol absorption, is in clinical development for the treatment of hypercholesterolemia. It is rapidly absorbed and glucuronidated in the intestine. The parent compound and its conjugated metabolite undergo enterohepatic recirculation, resulting in multiple peaks in the plasma concentration-time profile. OBJECTIVE: The purpose of this study was to develop a population pharmacokinetic (PPK) model for ezetimibe that incorporates enterohepatic recirculation. METHODS: A population compartment model incorporating input from the gallbladder, consistent with food intake, was developed to account for enterohepatic recirculation. The amount recycled was allowed to vary within a subject and between subjects, accommodating variability in bile secretion. The data used consisted of 90 profiles from healthy subjects who received single or multiple doses of ezetimibe 10 or 20 mg. Modeling was carried out using a nonlinear mixed-effect function in the S-PLUS statistical program. RESULTS: The amount of ezetimibe recycled into the central compartment was estimated to be approximately 17% to 20% of the total amount absorbed, independent of the volume of distribution. The intersubject coefficient of variation was 46% to 80% in the absorption rate constant, 27% in the distribution phase, and approximately 50% in the volume of distribution. CONCLUSIONS: PPK models adapted for enterohepatic recirculation allowed a formal assessment of the magnitude and frequency of the enterohepatic recirculation process, and the associated intersubject and intrasubject variability in healthy subjects. The PPK approach also helped to assess the correlation between the observed maximum or minimum (24 hours postdose) concentration with the model-based area under the curve, confirming the appropriateness of the former measures as a surrogate of drug exposure for a possible correlation with pharmacodynamics.

The pathological consequences of anaemia.

Many patients with chronic diseases such as chronic renal failure, chronic inflammatory bowel disease and rheumatoid arthritis are anaemic. Recently congestive heart failure (CHF) has also been found to be associated with anaemia. In all these diseases this anaemia or chronic disease is at least partially due to excessive production of cytokines and leukotrines that interfere both with the effect of erythropoietin (EPO) at the bone marrow and the release of stored iron in the reticuloendothelial system. Treating this anaemia with subcutaneous EPO and IV iron improves the weakness, fatigue, cachexia, nutritional state, mood, cognitive function and quality of life. In the case of CHF it also improves cardiac function and patient functional class, prevents deterioration of renal function and markedly reduces hospitalization. Very few agents in medicine improve so many aspects of the patient so well and so quickly. Unfortunately (for the suffering patient) this anaemia is often ignored and goes untreated.
