    Full Text Available Patients with chronic kidney disease (CKD exhibit an increased cancer risk compared to a healthy control population. To be able to estimate the cancer risk of the patients and to assess the impact of interventional therapies thereon, it is of particular interest to measure the patients’ burden of genomic damage. Chromosomal abnormalities, reduced DNA repair, and DNA lesions were found indeed in cells of patients with CKD. Biomarkers for DNA damage measurable in easily accessible cells like peripheral blood lymphocytes are chromosomal aberrations, structural DNA lesions, and oxidatively modified DNA bases. In this review the most common methods quantifying the three parameters mentioned above, the cytokinesis-block micronucleus assay, the comet assay, and the quantification of 8-oxo-7,8-dihydro-2′-deoxyguanosine, are evaluated concerning the feasibility of the analysis and regarding the marker’s potential to predict clinical outcomes.

    Dyspnea and exercise limitation are among the most common symptoms experienced by patients with various chronic lung diseases and are linked to poor quality of life. Our understanding of the source and nature of perceived respiratory discomfort and exercise intolerance in chronic lung diseases has increased substantially in recent years. These new mechanistic insights are the primary focus of the current review. Cardiopulmonary exercise testing (CPET) provides a unique opportunity to objectively evaluate the ability of the respiratory system to respond to imposed incremental physiological stress. In addition to measuring aerobic capacity and quantifying an individual's cardiac and ventilatory reserves, we have expanded the role of CPET to include evaluation of symptom intensity, together with a simple “non-invasive” assessment of relevant ventilatory control parameters and dynamic respiratory mechanics during standardized incremental tests to tolerance. This review explores the application of the new advances in the clinical evaluation of the pathophysiology of exercise intolerance in chronic obstructive pulmonary disease (COPD), chronic asthma, interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH). We hope to demonstrate how this novel approach to CPET interpretation, which includes a quantification of activity-related dyspnea and evaluation of its underlying mechanisms, enhances our ability to meaningfully intervene to improve quality of life in these pathologically-distinct conditions.

    Full Text Available BACKGROUND : Chronic obstructive pulmonary disease (COPD increases the risk of cardiovascular disease 2 - to 3 - fold. The factors responsible for this association remain largely unknown. Chronic obstructive pulmonary disease (COPD is the fourth leading cause of death world over. COPD has been defined as a disease state characterized by airflow limitation. Chronic obstructive pulmonary disease (COPD is a complex and heterogeneous clinical syndrome found in 6 – 8% of the entire population. In human being, the respiratory and circulatory systems are so intimately related that changes in one, sooner or later may cause changes in the other. In COPD patients, functional and structural changes of the respiratory syst em deeply influence cardiovascular function. Chronic obstructive pulmonary diseases (COPD, a broad spectrum of respiratory diseases represents a worldwide problem. Electrocardiographic (ECG findings may help in clinical decision making regarding this dis ease entity. AIMS AND OBJECTIVES : 1. To study various Electrocardiographic (ECG changes in patients of chronic obstructive pulmonary disease. 2. To find out the incidence of various ECG changes in patients of COPD . 3. To evaluate the extent of ECG changes among COPD patients suffering from broad spectrum of respiratory diseases.

    Full Text Available Chronic cough is a common problem in patients visiting physicians and its prevalence in different populations range from 3 to 40%. Postnasal drip, asthma and gastroesophageal reflux are the known cause of chronic cough. Although diagnosis of asthma is usually made by clinical signs and spirometeric results, methacholine challenge test is a good diagnostic test in patients who show normal physical examination and spirometeric results. In this study, the results of methacholine challenge test in chronic cough patients are investigated. This is a cross sectional study performed on patients suffering from chronic cough (over 8 weeks, who went to Pulmonary Disease Clinic of Imam Khomeini Hospital in 2006. Postnasal drip, gastroesophageal reflux was evaluated and ruled out in all patients. Then they were tested by methacholine inhalation using low to high doses of methacholine. The results of test was defined as 20% fall in FEV1 and its relationship with age, sex, history of allergic disease, family history of asthma and smoking status was investigated. 81 patients (36 female and 45 male entered this study who had mean age of 32.5 ± 13.06 years. 81.5% of patients had never smoked or closed contact with smokers, 6.2% were passive smokers, 8.6% were smokers and 3.7% had quit smoking. 37% had suffered from chronic cough less than 6 months, 11% for 6-11 months and 52% for more than 12 months. In 26% of patients, family history of asthma was present and 34.5% had a history of one type of allergy. In 29.5% the results of methacholine challenge test was positive, among them 45.8% showed an intense response and 54.2% a moderate response. The test results and its intensity had no statistically significant relationship with age, sex, smoking status, the duration of cough and family history of asthma, but the relationship between methacholine challenge test and the history of allergic disease was significant. Methacholine challenge test can be used as a

    Background Poor uptake and adherence are problematic for hospital-based pulmonary and heart failure rehabilitation programs, often because of access difficulties. The aims of this mixed-methods study were to determine the feasibility of a supervised exercise training program in a community gymnasium in people with chronic respiratory and chronic cardiac disease, to explore the experiences of participants and physiotherapists and to determine if a community venue improved access and adherence to rehabilitation. Methods Adults with chronic respiratory and/or chronic cardiac disease referred to a hospital-based pulmonary and heart failure rehabilitation program were screened to determine their suitability to exercise in a community venue. Eligible patients were offered the opportunity to attend supervised exercise training for 8 weeks in a community gymnasium. Semi-structured interviews were conducted with participants and physiotherapists at the completion of the program. Results Thirty-one people with chronic respiratory and chronic cardiac disease (34% males, mean [standard deviation] age 72 [10] years) commenced the community-based exercise training program. Twenty-two (71%) completed the program. All participants who completed the program, and the physiotherapists delivering the program, were highly satisfied, with reports of the community venue being well-equipped, convenient, and easily accessible. Using a community gymnasium promoted a sense of normality and instilled confidence in some to continue exercising at a similar venue post rehabilitation. However, factors such as cost and lack of motivation continue to be barriers. Conclusion The convenience and accessibility of a community venue for rehabilitation contributed to high levels of satisfaction and a positive experience for people with chronic respiratory and chronic cardiac disease and physiotherapists.

    Background The prevalence of chronic kidney disease (CKD) is high in general populations around the world. Targeted testing and screening for CKD are often conducted to help identify individuals that may benefit from treatment to ameliorate or prevent their disease progression. Aims This systematic review examines the methods used in economic evaluations of testing and screening in CKD, with a particular focus on whether test accuracy has been considered, and how analysis has incorporated issues that may be important to the patient, such as the impact of testing on quality of life and the costs they incur. Methods Articles that described model-based economic evaluations of patient testing interventions focused on CKD were identified through the searching of electronic databases and the hand searching of the bibliographies of the included studies. Results The initial electronic searches identified 2,671 papers of which 21 were included in the final review. Eighteen studies focused on proteinuria, three evaluated glomerular filtration rate testing and one included both tests. The full impact of inaccurate test results was frequently not considered in economic evaluations in this setting as a societal perspective was rarely adopted. The impact of false positive tests on patients in terms of the costs incurred in re-attending for repeat testing, and the anxiety associated with a positive test was almost always overlooked. In one study where the impact of a false positive test on patient quality of life was examined in sensitivity analysis, it had a significant impact on the conclusions drawn from the model. Conclusion Future economic evaluations of kidney function testing should examine testing and monitoring pathways from the perspective of patients, to ensure that issues that are important to patients, such as the possibility of inaccurate test results, are properly considered in the analysis.

    Although interleukin-17 (IL-17) is a recently discovered cytokine associated with several autoimmune diseases, its role in the pathogenesis of chronic graft-versus-host disease (cGVHD) was not established yet. The objective of this study was to investigate the association of IL17A and IL17F genes polymorphisms and IL-17A and IL-17F levels with cGVHD. IL-17A expression was also investigated in CD4+ T cells of patients with systemic cGVHD. For Part I of the study, fifty-eight allo-HSCT recipients and donors were prospectively studied. Blood samples were obtained to determine IL17A and IL17F genes polymorphisms. Cytokines levels in blood and saliva were assessed by ELISA at days +35 and +100 after HSCT. In Part II, for the immunophenotypic evaluation, eight patients with systemic cGVHD were selected and the expression of IL-17A was evaluated. We found association between recipient AA genotype with systemic cGVHD. No association was observed between IL-17A levels and cGVHD. Lower IL-17A levels in the blood were associated with AA genotype. In flow cytometry analysis, decreased expression of IL-17A was observed in patients with cGVHD after stimulation. In conclusion, IL-17A may have an important role in the development of systemic cGVHD. PMID:25136146

    Objective The aim of this study was to evaluate the effectiveness of mature red cell and reticulocyte parameters to identify three conditions: iron deficiency anemia, anemia of chronic disease, and anemia of chronic disease associated with absolute iron deficiency. Methods Peripheral blood cells from 117 adult patients with anemia were classified according to iron status, inflammation, and hemoglobinopathies as: iron deficiency anemia (n = 42), anemia of chronic disease (n = 28), anemia of chronic disease associated with iron deficiency anemia (n = 22), and heterozygous β-thalassemia (n = 25). The percentage of microcytic erythrocytes, hypochromic erythrocytes, and the levels of hemoglobin in both reticulocytes and mature red cells were determined. Receiver operating characteristic analysis was used to evaluate the accuracy of the parameters in differentiating anemia. Results There was no difference between the groups of iron deficiency and anemia of chronic disease associated with absolute iron deficiency for any of the parameters. The percentage of hypochromic erythrocytes was the best parameter to identify absolute iron deficiency in patients with anemia of chronic disease (area under curve = 0.785; 95% confidence interval: 0.661–0.909 with sensitivity of 72.7%, and specificity of 70.4%; cut-off value 1.8%). The formula microcytic erythrocyte count minus hypochromic erythrocyte count was very accurate to differentiate iron deficiency anemia from heterozygous β-thalassemia (area under curve = 0.977; 95% confidence interval: 0.950–1.005 with a sensitivity of 96.2%, and specificity of 92.7%; cut-off value 13.8). Conclusion The erythrocyte and reticulocyte indices are moderately good to identify absolute iron deficiency in patients with anemia of chronic disease. PMID:25818816

    Ragdoll breeder organisations often forewarn Ragdoll cat owners that renal problems may develop as a result of polycystic kidney disease (PKD), chronic interstitial nephritis, familial renal dysplasia or nephrocalcinosis. Healthy Ragdoll and non-Ragdoll cats were prospectively evaluated by measuring serum creatinine and urea concentrations, routine urinalysis and abdominal ultrasonography. All Ragdoll cats also underwent genetic PKD testing. One hundred and thirty-three Ragdoll and 62 control cats were included. Ragdoll cats had significantly lower serum urea concentrations and higher urinary specific gravity. However, median creatinine concentration, median urinary protein-to-creatinine ratio, and the proportion of cats with serum creatinine or urea concentration exceeding the reference interval did not differ. One or more renal ultrasonographical changes were detected in 66/133 (49.6%) Ragdoll and in 25/62 (40%) control cats. Ragdoll cats showed significantly more frequent segmental cortical lesions (7.5% versus 0%), abnormal renal capsule (19.5% versus 8%) and echogenic urine (51.9% versus 25.8%). Chronic kidney disease (CKD) was ultrasonographically suspected in 7/133 (5.3%) Ragdoll and in none of the control cats, which approached significance. Laboratory parameters confirmed kidney dysfunction only in 1/7 of these Ragdoll cats. All Ragdoll cats were PKD negative. In conclusion, first, breed-specific serum creatinine reference intervals are not likely required for Ragdoll cats. Second, renal ultrasonographical abnormalities are common, both in Ragdoll and non-Ragdoll cats. Third, healthy young Ragdoll cats are uncommonly affected by PKD and CKD, but an increased susceptibility of Ragdoll cats to develop CKD cannot be excluded. Finally, Ragdoll cats are predisposed to segmental cortical lesions, which may indicate renal infarction or cortical scarring.

    The purpose of this study was to evaluate the nutritional state and the prevalence of not transmissible chronic disease in elderly, who were participating in an assistance program of the Federal University of Alfenas (UNIFAL-MG), Alfenas, Minas Gerais, Brazil. Socio-economical, anthropometric and biochemical variables, as well as systemic blood pressure were collected from 82 individuals between 60 and 87 years of age, 90,2 % of them female. According to the body mass index (BMI) 52,4% of the studied sample were overweight, 28,0% eutrophic and 19,5% underweight; 37,8% presented high body fat percentage (BF%). With regard to the relation BMI/BF%, 63,4% of the elderly with overweight, 12,5% of the eutrophic and 11,8% of the underweight presented high BF%. The waist-to-hip ratio revealed 40,2% at high risk and 12,2% at very high risk of developing cardiovascular disease. In addition, 22,0% had high blood pressure. The biochemical tests revealed that 39,3%, 39,3% and 3,3% presented higher plasma cholesterol, triglyceride and glucose levels respectively. There is a need for continuous nutritional education programs and monitoring of the nutritional and health status for improving the quality of life of the studied individuals.

    Computed tomography (CT) of the hip was done on 37 patients those who have been suffered from chronic hip joint pain. There were 18 patients of avascular necrosis of hip (AVN), 67% of whom were affected bilaterally, 15 patients of degenerative arthritis (DA), 33% bilaterally; one patient of tuberculous arthritis, rheumatoid arthritis and traumatic arthritis respectively. Comparison of the staging by means of the CT and plain film showed good correlation between the two methods. The CT findings of the AVN and OA were also compared; crescent sign or fissure, loss of congruity, and loss or change of normal asterisk sign were more commonly seen in AVN. Acetabular change especially associated cystic appearance, osteophytes formation and joint narrowing were more frequent in OA. CT showed primary and secondary change of AVN and OA more clearly without confusion than plain film. We think that CT can be helpful in evaluation and understanding of each disease process and differentiation of the two lesions in difficult case000.

    Purpose: To evaluate the hemodynamic changes in the extraocular orbital vessels of the patients with chronic obstructive pulmonary disease (COPD), using color Doppler ultrasonography (CDU) technique, and to compare the results with those of healthy control subjects. Methods: Forty-five patients with COPD and 17 healthy control subjects were included in this study. Patients with COPD were classified according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Fifteen patients of stage I COPD (mild airflow limitation), stage II COPD (worsening airflow limitation) or stage III COPD (severe airflow limitation) were enrolled into Group I, II and III, respectively. End tidal carbon dioxide (EtCO{sub 2}), peripheral oxygen saturation (SpO{sub 2}), pulse rate (PR) and respiratory rate (RR) were measured by using capnograph/pulse oximeter in all patients. Measurements were performed in only one randomly chosen eye of each participant. The peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistance index (RI) were measured in the ophthalmic artery (OA), central retinal artery (CRA), lateral short posterior ciliary artery (LPCA) and medial short posterior ciliary artery (MPCA), using CDU technique. Results: The PSV measurements of the OA were significantly higher in Groups II and III compared to control group (p < 0.01, p < 0.001, respectively). The RI values from OA and CRA were significantly higher in Group II and III than the control group (p < 0.05). The RI values of LPCA and MPCA were also significantly higher in Group II than the control subjects (p < 0.05). When RI values were compared, mean values of LPCA and MPCA were significantly lower in Group III than in Group II (p < 0.05). There were no significant differences between Group I and control patients about PSVs, EDVs and RI values of all arteries Statistically significant correlations were found for the EtCO{sub 2} with PSV (r = 0.53, p < 0.01) and EDV (r = 0.51, p < 0.01) of the

    Full Text Available Though there are few studies addressing brainstem auditory evoked potentials (BAEP in patients with chronic obstructive pulmonary disease (COPD, subclinical BAEP abnormalities in stable COPD patients have not been studied. The present study aimed to evaluate the BAEP abnormalities in this study group. Materials and Methods : In the present study, 80 male subjects were included: COPD group comprised 40 smokers with stable COPD with no clinical neuropathy; 40 age-matched healthy volunteers served as the control group. Latencies of BAEP waves I, II, III, IV, and V, together with interpeak latencies (IPLs of I-III, I-V, and III-V, and amplitudes of waves I-Ia and V-Va were studied in both the groups to compare the BAEP abnormalities in COPD group; the latter were correlated with patient characteristics and Mini-Mental Status Examination Questionnaire (MMSEQ scores to seek any significant correlation. Results: Twenty-six (65% of the 40 COPD patients had BAEP abnormalities. We observed significantly prolonged latencies of waves I, III, V over left ear and waves III, IV, V over right ear; increased IPLs of I-V, III-V over left ear and of I-III, I-V, III-V over right side. Amplitudes of waves I-Ia and V-Va were decreased bilaterally. Over left ear, the latencies of wave I and III were significantly correlated with FEV 1 ; and amplitude of wave I-Ia, with smoking pack years. A weak positive correlation between amplitude of wave I-Ia and duration of illness; and a weak negative correlation between amplitude of wave V-Va and MMSEQ scores were seen over right side. Conclusions : We observed significant subclinical BAEP abnormalities on electrophysiological evaluation in studied stable COPD male patients having mild-to-moderate airflow obstruction.

    Full Text Available Background/Aims: Either protein-to-creatinine ratio (PCR or albumin-to-creatinine ratio (ACR can be adopted for estimation of proteinuria in patients with chronic kidney disease (CKD. Estimated protein excretion rate (ePER and estimated albumin excretion rate (eAER may be superior to ACR and PCR. Reports show that urine albumin-to-protein ratio (APR may be useful in detecting tubular proteinuria, but should be compared with urine protein electrophoresis (PEP. Methods: Both 24-h urine and spot urine were collected from 77 stable CKD patients for measurement of albumin, protein, and creatinine, and PEP. Based on MDRD and CKD-EPI equations, ePERMDRD, ePERCKD-EPI, eAERMDRD and eAERCKD-EPI were calculated to estimate daily proteinuria and albuminuria. Glomerular CKD was defined by clinical and/or pathological evidence. Results: ACR correlated significantly with PCR. However, microalbuminuria was present in patients without pathologic proteinuria. Twenty-four-hour urine albumin correlated better with eAERMDRD and eAERCKD-EPI than ACR, and 24-h urine protein correlated better with ePERMDRD and ePERCKD-EPI than PCR. APR significantly but not well correlated with the albumin fraction in urine PEP. The albumin fraction obtained from urine PEP was significantly higher in patients with glomerulopathy than those with non-glomerular CKD, whereas there were no differences in APR between groups. In contrast with APR, the albumin fraction in urine PEP was independently associated with glomerular CKD. Conclusions: Both PCR and ACR are useful in evaluation of proteinuria. In quantifying daily proteinuria and albuminuria, ePER and eAER are superior to PCR and ACR, respectively. Compared with APR, urine PEP is more useful in diagnosing glomerular proteinuria.

    Full Text Available Objective: To evaluate adherence to medication and study factors associated with non-adherence in chronic kidney disease (CKD patients. Methods: A prospective, cross-sectional, questionnaire based study was conducted in Nephrology department of a super specialty hospital. Patients above 18 years of age, suffering from CKD from six months or more were interviewed using self-designed, semi-structured questionnaire to get information about adherence to medication, diet restriction and lifestyle modification (n = 150. Morisky medication adherence questionnaire was used to calculate overall adherence. In this higher score indicates poor adherence. Main outcome measures included prevalence of non-adherence and factors associated with the same. Results: Average number of medicines taken by each patient was 8.0+1.612 (mean+SD per day. Non-adherence to medication schedule was reported in 34% patients. Common causes of non-adherence were high cost (21.3%, complex dosing schedule (20%, fear of adverse effects (16%. Sixty-eight% patients were not aware about importance of taking each medicine. Sixteen% stopped taking medicines due to high cost. Forty-two% suggested that government should adopt measures to provide free medicines to poor patients. In Morisky medication adherence questionnaire high, medium and low adherence was reported in 7.3%, 55.3% and 37.3% of patients, respectively. Moderately positive correlation was observed between poor adherence and number of concurrent illnesses and number of medicines taken. Conclusion: Since majority of patients were not aware about importance of taking each medicine, creating awareness about the same is essential for improving adherence to therapy. Measures to provide free medicines to non-affording patients need to be implemented since high cost was other major cause of non-adherence.

    Full Text Available The global prevalence of physiologically defined chronic obstructive pulmonary disease (COPD in adults aged >40 yr is approximately 9-10 per cent. Recently, the Indian Study on Epidemiology of Asthma, Respiratory Symptoms and Chronic Bronchitis in Adults had shown that the overall prevalence of chronic bronchitis in adults >35 yr is 3.49 per cent. The development of COPD is multifactorial and the risk factors of COPD include genetic and environmental factors. Pathological changes in COPD are observed in central airways, small airways and alveolar space. The proposed pathogenesis of COPD includes proteinase-antiproteinase hypothesis, immunological mechanisms, oxidant-antioxidant balance, systemic inflammation, apoptosis and ineffective repair. Airflow limitation in COPD is defined as a postbronchodilator FEV1 (forced expiratory volume in 1 sec to FVC (forced vital capacity ratio <0.70. COPD is characterized by an accelerated decline in FEV1. Co morbidities associated with COPD are cardiovascular disorders (coronary artery disease and chronic heart failure, hypertension, metabolic diseases (diabetes mellitus, metabolic syndrome and obesity, bone disease (osteoporosis and osteopenia, stroke, lung cancer, cachexia, skeletal muscle weakness, anaemia, depression and cognitive decline. The assessment of COPD is required to determine the severity of the disease, its impact on the health status and the risk of future events (e.g., exacerbations, hospital admissions or death and this is essential to guide therapy. COPD is treated with inhaled bronchodilators, inhaled corticosteroids, oral theophylline and oral phosphodiesterase-4 inhibitor. Non pharmacological treatment of COPD includes smoking cessation, pulmonary rehabilitation and nutritional support. Lung volume reduction surgery and lung transplantation are advised in selected severe patients. Global strategy for the diagnosis, management and prevention of Chronic Obstructive Pulmonary Disease

    Indium-111 leukocyte scanning and colonoscopy were performed in 19 children and adolescents with chronic inflammatory bowel disease to study the correlation of evaluation between these two diagnostic modalities in comparison to histologic study for colonic disease. Seven patients had ulcerative colitis, 10 had Crohn's disease, and two patients had no specific diagnosis after evaluation. The sensitivity of indium-111 scan was 18%, specificity was 62.5%, and accuracy for diagnosing colonic disease was only 37%. In comparison, sensitivity and specificity for colonoscopy were 100 and 57%, respectively. Furthermore, accuracy with colonoscopy was 84%. The authors data suggest that the usefulness of scans is limited to patients in whom standard diagnostic procedures are contraindicated. In addition, it is essential to confirm the visual diagnostic impression on colonoscopy with histologic study.

  19. From liver biopsy to non-invasive markers in evaluating fibrosis in chronic liver disease

    2015-08-01

    Full Text Available Chronic liver disease is a late stage of progressive hepatic fibrosis. It consists of functional and structural disruptions in most chronic liver diseases. An accurate diagnosis allows us to establish the degree of fibrosis and the stage of the disease, the prognosis of the patient and to predict a treatment response. Despite the fact that liver biopsy is considered a gold standard, noninvasive methods for diagnosing liver fibrosis have gained more and more importance. Whether we talk about serum biomarkers or imagistic methods from transient elastography to 3-D magnetic resonance elastography, the question remains: are these useful or useless? Serum biomarkers represent blood components that can reflect liver histological changes, thus they can monitor the continuous process of fibrosis. These can be subcategorized in direct (that show extracellular matrix turnover and indirect markers (that reflect disturbances in the hepatic function. However these markers alone are not as accurate in the staging of fibrosis, only help differentiate patients without or with low grade of fibrosis from those with significant fibrosis and cannot be considered alone in the diagnosis of liver fibrosis. Imagistic methods include: ultrasound-based transient elastography, magnetic resonance elastography (MRE, 2D-shear wave elastography, acoustic radiation impulse imaging (ARFI and cross sectional imaging, the first being the most used. Using a combination of non-invasive tools allows us to diminish the number of patients in need of liver biopsy. However, the patient must always be informed of the advantages and disadvantages of each method and its limitations.

    Full Text Available Introduction. The exacerbation of chronic obstructive pulmonary disease is most often induced by an infection of bacterial origin in over 50% of the cases (or mixed bacterial and viral infection. This study was aimed at evaluating clinical effects of antibiotics co-amoxiclav. Amoxiicillin with clavulanic acid in the treatment of patients with severe chronic obstructive pulmonary disease exacerbation. Material and Methods. The investigation included 38 patients with severe chronic obstructive pulmonary disease exacerbation hospitalized at the Institute for Pulmonary Diseases of Vojvodina, Sremska Kamenica. The patients were randomly selected for the antibiotic treatment with Amoxiclav twice a day in 12 hour intervals. The clinical effects of the applied treatment were evaluated by analyzing certain laboratory findings, microbiological sputum findings and improvement of subjective symptoms. Results. Of the examined subjects, 65% were males and 35% were females, their mean age being 66.4+8.86, and who were mostly smokers (73%. After the completion of applied antibiotic treatment, a significant reduction and normalization of all inflammation markers were recorded, as well as a significant improvement of the patients’ subjective symptoms. The positive microbiological sputum findings (Haemophilus influenzae, Pseudomonas aeruginosa and Streptococcus pneumoniae were recorded in 13.58% of the patients. The bacterial agent was eradicated on the third day of the applied treatment. The mean length of the treatment was 7.07+0.91 days, with no undesirable treatment side effects observed. Conclusion. The antibiotic therapy is justifiable as the initial treatment regimen of severe chronic obstructive pulmonary disease exacerbation and amoxicillin with clavulanic acid is reported as the first-line antibiotic drug in most pharmacotherapy guidelines.

    Full Text Available Background: Chronic obstructive pulmonary disease (COPD has considerable effects on cardiac functions, including those of the right ventricle, left ventricle, and pulmonary blood vessels. Most of the increased mortality associated with COPD is due to cardiac involvement. Echocardiography provides a rapid, noninvasive, portable, and accurate method to evaluate the cardiac changes. Aims: To assess the cardiac changes secondary to COPD by echocardiography and to find out the correlation between echocardiographic findings and severity of COPD, if there is any. Materials and Methods: A total 40 of patients of COPD were selected and staged by pulmonary function test (PFT and evaluated by echocardiography. Results: On echocardiographic evaluation of COPD, 50% cases had normal echocardiographic parameters. Measurable tricuspid regurgitation (TR was observed in 27/40 cases (67.5%. Pulmonary hypertension (PH, which is defined as systolic pulmonary arterial pressure (sPAP > 30 mmHg was observed in 17/27 (63% cases in which prevalence of mild, moderate, and severe PH were 10/17 (58.82%, 4/17 (23.53%, and 3/17 (17.65%, respectively. The frequencies of PH in mild, moderate, severe, and very severe COPD were 16.67%, 54.55%, 60.00%, and 83.33%, respectively. Right atrial pressure was 10 mmHg in 82.5% cases and 15 mmHg in 17.5% cases. Cor pulmonale was observed in 7/17 (41.17% cases; 7.50% cases had left ventricle (LV systolic dysfunction and 47.5% cases had evidence of LV diastolic dysfunction defined as A ≥ E (peak mitral flow velocity of the early rapid filling wave (E, peak velocity of the late filling wave caused by atrial contraction (A on mitral valve tracing. Left ventricle hypertrophy was found in 22.5% cases. Conclusion : Prevalence of PH has a linear relationship with severity of COPD and severe PH is almost associated with cor pulmonale. Echocardiography helps in early detection of cardiac complications in COPD cases giving time for early

    Over the past decades numerous markers of the tumor burden have been discovered in chronic lymphocytic leukemia (CLL). Among these, the microRNAs seem to have a promising role. The development and validation of miRNAs as biomarkers should have significant impact in improving early cancer detection and diagnosis, enhancing therapeutic success, and increasing the life expectancy of patients. We identified miR-181b as a biomarker for the progression of this disease from indolent to aggressive. For this study we used sequential samples from patients with either progressive or stable course of the illness. Here, we discuss more extensively this issue by adding novel findings and introducing a novel approach for monitoring CLL patients.

    Chronic obstructive pulmonary disease (COPD), a disease manifested by significantly impaired airflow, afflicts ∼14.2 million cases in the United States alone with an estimated 63 million people world-wide. Although there are a number of causes, the predominant cause is excessive tobacco smoke. In fact, in China, there have been estimates of 315,000,000 people that smoke. Other less frequent causes are associated with indirect cigarette smoke, air pollutants, biomass fuels, and genetic mutations. COPD is often associated with heart disease, lung cancer, osteoporosis and conditions can worsen in patients with sudden falls. COPD also affects both innate and adaptive immune processes. Cigarette smoke increases the expression of matrix metalloproteases and proinflammatory chemokines and increases lung titers of natural killer cells and neutrophils. Yet, neutrophil reactive oxygen species (ROS) mediated by the phagocytic respiratory burst and phagocytosis is impaired by nicotine. In contrast to innate immunity in COPD, dendritic cells represent leukocytes recruited to the lung that link the innate immune responses to adaptive immune responses by activating naïve T cells through antigen presentation. The autoimmune process that is also a significant part of inflammation associated with COPD. Moreover, coupled with restricted FEV1 values, are the prevalence of patients with single or multiple infections by bacteria, viruses and fungi. Finally, we focus on one of the more problematic infectious agents, the Gram-negative opportunistic pathogenic bacterium, Pseudomonas aeruginosa. Specifically, we delve into the development of highly problematic biofilm infections that are highly refractory to conventional antibiotic therapies in COPD. We offer a non-conventional, biocidal treatment that may be effective for COPD airway infections as well as with combinations of current antibiotic regimens for more effective treatment outcomes and relief for patients with COPD.

    Frances D. Butterfoss, PhD

    2005-03-01

    Full Text Available Introduction Implicit in public health planning models is the assumption that good public health plans lead to good programs, and good programs lead to desired health outcomes. Despite considerable resources that are devoted to developing plans, public health agencies and organizations have lacked a tool for evaluating the finished product of their planning efforts — the written plan itself — as an important indicator of progress. To address the need for an instrument to assess the quality of state plans designed to prevent and control chronic diseases, we created and tested the State Plan Index and used it to evaluate the quality of nine state plans aimed at preventing and reducing obesity. Methods The State Plan Index was developed under the auspices of the Centers for Disease Control and Prevention (CDC in collaboration with public health experts in federal, state, and academic settings. The State Plan Index included 55 items related to plan quality arranged into nine components. Each item was rated on a Likert scale from 0 to 5, with 5 being the highest rating. Each plan also received a separate overall plan quality score using the same scale. Each state plan was evaluated by four or five raters using the State Plan Index. For each plan, the 55 items were averaged to calculate an item average score, and a subscore was calculated for each State Plan Index component. Finally, five states also self-rated their own plans (self score. Results The mean item average score for all plans was 2.4 out of 5.0. The range of item average scores was 1.0 to 3.0. The component of the State Plan Index with the highest mean component score (3.3 was Presentation of Epidemiologic Data on Disease Burden. The components with the lowest component scores were Resources for Plan Implementation (0.7; Integration of Obesity Efforts with Other Chronic Disease Efforts (1.7; and Program Evaluation (2.0. Plan quality was rated higher when based on the single overall plan

    Full Text Available Background : Some patients with chronic obstructive pulmonary disease (COPD may benefit from oral steroid therapy. These steroid-responsive patients are diagnosed based on laboratory spirometry. We hypothesize that daily, home-based spirometry is a better tool. Methods : Thirty patients with COPD underwent a single-blinded study, with a crossover design. They received 2 weeks of placebo followed by 2 weeks of prednisone therapy (40 mg/day. Laboratory spirometry was done at the beginning and end of the study and daily home-based spirometry was done twice a day. Results : Analysis of variance model was used. The variability of the median day-to-day forced expiratory volume in 1 s (FEV 1 was 72.5 mL (25th percentile of 40 mL and 75th percentile of 130 mL. The daily FEV 1 variation was 70 mL (25th percentile of 50 mL and 75th percentile of 100 mL. The overall laboratory FEV 1 variability was larger after the steroid course (P < 0.001, but not clinically significant. The variability was not significant postplacebo treatment compared with the baseline values. For home-based spirometry, steroid treatment was not significantly different. The majority (97% completed more than 80% of the measurements. Ninety percent of the performed tests were considered acceptable. Only 53% of the tests were considered accurate. Overall both laboratory and home-based measurements did not show significant association between airway responsiveness and dyspnea or exercise capacity. Conclusion : Twice-daily home measurements of FEV 1 might be better than the conventional approach to identify steroid responsive COPD patients. However, this finding was only statistically but not clinically significant. Therefore, we would not recommend this approach to identify COPD patients with steroid responsiveness.

    Full Text Available Abstract Background Despite optimal pharmacological therapy and pulmonary rehabilitation, patients with COPD continue to be breathless. There is a need to develop additional strategies to alleviate symptoms. Learning to sing requires control of breathing and posture and might have benefits that translate into daily life. Methods To test this hypothesis we performed a randomised controlled trial, comparing a six week course of twice weekly singing classes to usual care, in 28 COPD patients. The experience of singing was assessed in a qualitative fashion, through interviews with a psychologist. In addition, we surveyed patients with chronic respiratory conditions who participated in a series of open singing workshops. Results In the RCT, the physical component score of the SF36 improved in the singers (n = 15 compared to the controls (n = 13; +7.5(14.6 vs. -3.8(8.4 p = 0.02. Singers also had a significant fall in HAD anxiety score; -1.1(2.7 vs. +0.8(1.7 p = 0.03. Singing did not improve single breath counting, breath hold time or shuttle walk distance. In the qualitative element, 8 patients from the singing group were interviewed. Positive effects on physical sensation, general well-being, community/social support and achievement/efficacy emerged as common themes. 150 participants in open workshops completed a questionnaire. 96% rated the workshops as "very enjoyable" and 98% thought the workshop had taught them something about breathing in a different way. 81% of attendees felt a "marked physical difference" after the workshop. Conclusion Singing classes can improve quality of life measures and anxiety and are viewed as a very positive experience by patients with respiratory disease; no adverse consequences of participation were observed.

  16. Understanding anemia of chronic disease.

    2015-01-01

    The anemia of chronic disease is an old disease concept, but contemporary research in the role of proinflammatory cytokines and iron biology has shed new light on the pathophysiology of the condition. Recent epidemiologic studies have connected the anemia of chronic disease with critical illness, obesity, aging, and kidney failure, as well as with the well-established associations of cancer, chronic infection, and autoimmune disease. Functional iron deficiency, mediated principally by the interaction of interleukin-6, the iron regulatory hormone hepcidin, and the iron exporter ferroportin, is a major contributor to the anemia of chronic disease. Although anemia is associated with adverse outcomes, experimental models suggest that iron sequestration is desirable in the setting of severe infection. Experimental therapeutic approaches targeting interleukin-6 or the ferroportin-hepcidin axis have shown efficacy in reversing anemia in either animal models or human patients, although these agents have not yet been approved for the treatment of the anemia of chronic disease.

    2012-01-01

    Full Text Available INTRODUCTION: Patients' perception about their health condition, mainly involving chronic diseases, has been investigated in many studies and it has been associated to depression, compliance with the treatment, quality of life and prognosis. The Illness Effects Questionnaire (IEQ is a tool which makes the standardized evaluation of patients' perception about their illness possible, so that it is brief and accessible to the different clinical settings. This work aims to begin the transcultural adaptation of the IEQ to Brazil through the validated translation and the reliability study. METHODS: The back-translation method and the test-retest reliability study were used in a sample of 30 adult patients under chronic hemodialysis. The reliability indexes were estimated using the Pearson, Spearman, Weighted Kappa and Cronbach's alpha coefficients. RESULTS: The semantic equivalence was reached through the validated translation. In this study, the reliability indexes obtained were respectively: 0.85 and 0.75 (p < 0.001; 0.68 and 0.92 (p < 0.0001. DISCUSSION: The reliability indexes obtained attest to the stability of responses in both evaluations. Additional procedures are necessary for the transcultural adaptation of the IEQ to be complete. CONCLUSION: The results indicate the translation validity and the reliability of the Brazilian version of the IEQ for the sample studied.

    2016-05-01

    Full Text Available Chronic kidney disease (CKD is a growing problem in Nigeria, presenting challenges to the nation’s health and economy. This study evaluates the accessibility to healthcare in Edo State of CKD patients diagnosed between 2006 and 2009. Using cost analysis techniques within a geographical information system, an estimated travel time to the hospital was used to examine the spatial accessibility of diagnosed patients to available CKD healthcare in the state. The results from the study indicated that although there was an annual rise in the number of diagnosed cases, there were no significant changes in the proportion of patients that were diagnosed at the last stage of CKD. However, there were indications that the travel time to the hospital for CKD treatment might be a contributing factor to the number of diagnosed CKD cases. This implies that the current structure for CKD management within the state might not be adequate.

    The purpose of this study was to estimate sodium intake in a group of patients with chronic kidney disease (CKD) and to correlate the results with the urinary excretion values of sodium and signs of fluid overload. We included patients with CKD in different stages. Urinary sodium was measured in 24 h urine samples. Body composition monitor (BCM) was used to estimate the hydration status. Sixty patients (38 ± 15 ml/min of GFR) presented 4.14 ± 1.71 g/24 h of urinary sodium excretion. Overhydration was detected in 50% of the patients by the BCM. There was a positive correlation between the measured sodium excretion values and BCM, ICW, ECW and TBW. In conclusion, markers of overhydration evaluated by BCM were positively correlated with urinary sodium excretion.

    This article reviews the association of chronic renal disease and pregnancy. Included are discussions of guidelines for counseling pregnant women with underlying chronic renal disease who are considering conceiving as well as management of those already pregnant. Specifically highlighted are recent studies that question the validity of using estimated glomerular filtration rate and other formulae and questions of whether we should strive to replace the classic counseling approaches based primarily on serum creatinine levels with guidelines based on chronic kidney disease classification. The article concludes with a review as well as a critique of recent research on the prevalence of preeclampsia in women with underlying chronic renal disease, as well as if women with preeclampsia and underlying kidney disease have accelerated courses toward end-stage renal disease.

    2008-01-01

    Whether acute recurrent pancreaUtis is a chronic disease is still debated and a consensus is not still reached as demonstrated by differences in the classification of acute recurrent pancreatitis.There is major evidence for considering alcoholic pancreatitis as a chronic disease ab initio while chronic pancreatitis lesions detectable in biliary acute recurrent pancreatitis (ARP) seem a casual association.Cystic fibrosis transmembrane con ductance regulator (CFTR) gene mutation,hereditary and obstructive pancreatitis seem an acute disease that progress to chronic pancreatitis,likely as a consequence of the activation and proliferation of pancreatic stellate cells that produce and activate collagen and therefore fibrosis.From the diagnostic point of view,in patients with acute recurrent pancreatitis Endoscopic ultrasound (EUS) seems the more reliable technique for an accurate evaluation and follow-up of some ductal and parenchymal abnormalities suspected for early chronic pancreatitis.

    Lyme disease is a tick-borne illness endemic to Minnesota that can have potentially severe complications. As the incidence of Lyme disease continues to increase, it is important for physicians in Minnesota to become familiar with its clinical aspects, including the concept of "chronic Lyme disease." Chronic Lyme disease is a misnomer that is often applied to patients with nonspecific presentations who may or may not have a history of infection with Borrelia burgdorferi, the agent that causes Lyme disease. When a patient does present with persistent nonspecific symptoms attributed to chronic Lyme disease, clinicians should ascertain the presence of objective manifestations, obtain laboratory results, and get a history of tick exposure. If active infection with B. burgdorferi is unlikely, they should avoid prescribing empiric antibiotic therapy and instead thoroughly evaluate the patient for other possible causes of the complaints and recommend appropriate care.

    Portal circulation can be evaluated in a relatively noninvasive way by per-rectal portal scintigraphy. We used this method to evaluate portal hemodynamics in patients with chronic liver diseases and underlying hepatic viral infection; the patients did not need surgery or sclerotherapy, or refused it, so changes in the natural course were identified. A solution of Tc-99m pertechnetate was instilled into the rectum, and serial scintigrams were taken while radioactivity curves for the liver and heart were produced. The per-rectal portal shunt index was calculated from the curves. In a longitudinal study, 70 patients (9 with mild chronic hepatitis, 10 with moderate chronic hepatitis, 7 with severe chronic hepatitis, 22 with cirrhosis but without varices, and 22 with both cirrhosis and varices) were examined at least twice at intervals of 12-102 months (mean, 39 months). The shunt index was higher for more severe disorders, increasing in the order of mild chronic hepatitis, moderate chronic hepatitis, severe chronic hepatitis, cirrhosis without varices, and cirrhosis with varices. The mean annual changes in the mean shunt index were 1.0% in mild chronic hepatitis, 4.4% in moderate chronic hepatitis, 6.1% in severe chronic hepatitis, 10.7% in cirrhosis without varices, and 6.2% in cirrhosis and varices. Cirrhotic patients were arbitrarily divided into two groups of roughly equal size on the basis of the shunt index at the first examination. In those with a shunt index of 30% or more, the mean annual change was 4.7%. The patients with a shunt index of less than 30% had a mean annual change of 11.8%. Changes in the portal hemodynamics were not steady. The shunt index rose gradually as disease advanced from mild to moderate and to severe chronic hepatitis and cirrhosis of the liver, after which the index rose rapidly when varices developed, slowing later.

    Rationale and objectives: Emphysema and small airway obstruction are the pathological hallmarks of chronic obstructive pulmonary disease (COPD). The aim of this pilot study in a small group of chronic obstructive pulmonary disease (COPD) patients was to quantify hyperpolarized helium-3 ({sup 3}He) magnetic resonance imaging (MRI) functional and structural measurements and to explore the potential role for {sup 3}He MRI in detecting the lung structural and functional COPD phenotypes. Materials and methods: We evaluated 20 ex-smokers with stage I (n = 1), stage II (n = 9) and stage III COPD (n = 10). All subjects underwent same-day plethysmography, spirometry, {sup 1}H MRI and hyperpolarized {sup 3}He MRI at 3.0 T. {sup 3}He ventilation defect percent (VDP) was generated from {sup 3}He static ventilation images and {sup 1}H thoracic images and the {sup 3}He apparent diffusion coefficient (ADC) was derived from diffusion-weighted MRI. Results: Based on the relative contribution of normalized ADC and VDP, there was evidence of a predominant {sup 3}He MRI measurement in seven patients (n = 3 mainly ventilation defects or VDP dominant (VD), n = 4 mainly increased ADC or ADC dominant (AD)). Analysis of variance (ANOVA) showed significantly lower ADC for subjects with predominantly elevated VDP (p = 0.02 compared to subjects with predominantly elevated ADC; p = 0.008 compared to mixed group) and significantly decreased VDP for subjects with predominantly elevated ADC (p = 0.003, compared to mixed group). Conclusion: In this small pilot study, a preliminary analysis shows the potential for {sup 3}He MRI to categorize or phenotype COPD ex-smokers, providing good evidence of feasibility for larger prospective studies.

    The relationships between chronic liver diseases and trace element (TE) contents are debated. Particularly, no defined data are available about the TE levels in viral liver disease patients with or without malnutrition. In this study we evaluated blood and plasma levels of various trace elements in patients with HCV-related chronic liver disease, at different stages of liver damage (8 patients with chronic hepatitis and 32 with liver cirrhosis) with or without malnutrition. We also studied 10 healthy volunteers as control group. We found that cirrhotic subjects had a significant decrease of blood levels of Zn and Se, independently on the nutritional status, whereas plasma levels of Fe were significantly reduced only in malnourished cirrhotic patients. Our data indicate that liver impairment is the main cause of the blood decrease of Se and Zn levels in patients with non alcoholic liver disease, whereas the malnutrition affects Fe levels only.

    2006-12-01

    The purpose of this review was to examine the impact of varying degrees of renal insufficiency on pregnancy outcome in women with chronic renal disease. Our search of the literature did not reveal any randomized clinical trials or meta-analyses. The available information is derived from opinion, reviews, retrospective series, and limited observational series. It appears that chronic renal disease in pregnancy is uncommon, occurring in 0.03-0.12% of all pregnancies from two U.S. population-based and registry studies. Maternal complications associated with chronic renal disease include preeclampsia, worsening renal function, preterm delivery, anemia, chronic hypertension, and cesarean delivery. The live birth rate in women with chronic renal disease ranges between 64% and 98% depending on the severity of renal insufficiency and presence of hypertension. Significant proteinuria may be an indicator of underlying renal insufficiency. Management of pregnant women with underlying renal disease should ideally entail a multidisciplinary approach at a tertiary center and include a maternal-fetal medicine specialist and a nephrologist. Such women should receive counseling regarding the pregnancy outcomes in association with maternal chronic renal disease and the effect of pregnancy on renal function, especially within the ensuing 5 years postpartum. These women will require frequent visits and monitoring of renal function during pregnancy. Women whose renal disease is further complicated by hypertension should be counseled regarding the increased risk of adverse outcome and need for blood pressure control. Some antihypertensives, especially angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers, should be avoided during pregnancy, if possible, because of the potential for both teratogenic (hypocalvaria) and fetal effects (renal failure, oliguria, and demise).

    Objectives: Statins by their anti-inflammatory and endothelial stabilizing effect can be beneficial in patients with chronic obstructive pulmonary disease (COPD) and pulmonary hypertension (PH). The present study was done to evaluate the effect of rosuvastatin on pulmonary functions and quality of life (QOL) in patients with concomitant COPD and PH. Materials and Methods: It was a prospective, randomized, double-blind, placebo-controlled, study conducted in patients with COPD and PH. A total of sixty patients were assigned to receive either rosuvastatin 10 mg or placebo once a day in addition to their conventional treatment for 12 weeks. Routine blood investigations, pulmonary functions, echocardiogram, exercise capacity, and QOL using a questionnaire were assessed at the baseline and after 12 weeks. Results: In patients of rosuvastatin group, there was a statistically significant increase in peak expiratory flow rate (PEFR) (P = 0.04) but no significant change in other pulmonary functions: Forced vital capacity (FVC), forced expiratory volume at 1 s (FVC, FEV1, FEV1/FVC), and echocardiogram parameters. There was a significant increase in 6-min walk test (6-min walk distance) (P = 0.03) at the end of 12 weeks. On comparing with placebo, rosuvastatin showed a significant reduction (P = 0.045) in COPD exacerbations while adverse effects did not differ. Conclusion: Statins have a favorable effect on patients with COPD and PH regarding the improvement in PEFR, COPD exacerbations, and exercise capacity. Such effects can be beneficial in these patients and more so in patients with concomitant coronary artery disease or hyperlipidemia where long-term benefits of statins have been established.

    Full Text Available Effective community-level chronic disease prevention is critical to population health within developed and developing nations. Pasos Adelante is a preventive intervention that aims to reduce chronic disease risk with evidence of effectiveness in US-Mexico residing, Mexican origin, participants. This intervention and related ones also implemented with community health workers have been shown to improve clinical, behavioral and quality of life indicators; though most evidence is from shorter-term evaluations and/or lack comparison groups. The current study examines the impact of this program using secondary data collected in the community 3–6 years after all participants completed the program. A proportional household survey (N = 708 was used that included 48 respondents who indicated they had participated in Pasos. Using propensity score matching to account for differences in program participants versus other community residents (the program targeted those with diabetes and associated risk factors, 148 natural controls were identified for 37 matched Pasos participants. Testing a range of behavioral and clinical indicators of chronic disease risk, logistic regression models accounting for selection bias showed two significant findings; Pasos participants were more physically active and drank less whole milk. These findings add to the evidence of the effectiveness of Pasos Adalente and related interventions in reducing chronic disease risk in Mexican-origin populations, and illustrate the use of innovative techniques for using secondary, community-level data to complement prior evaluation research.

    Medication nonadherence remains a significant obstacle to achieving improved health outcomes in patients with chronic disease. Self-efficacy, the confidence in one's ability to perform a given task such as taking one's medications, is an important determinant of medication adherence, indicating the need for reliable and valid tools for measuring this construct. This study sought to develop a self-efficacy scale for medication adherence in chronic disease management that can be used in patients with a broad range of literacy skills. The Self-efficacy for Appropriate Medication Use (SEAMS) was developed by a multidisciplinary team with expertise in medication adherence and health literacy. Its psychometric properties were evaluated among 436 patients with coronary heart disease and other comorbid conditions. Reliability was evaluated by measuring internal consistency and test-retest reliability. Principal component factor analysis was performed to evaluate the validity of the SEAMS. Reliability and validity analyses were also performed separately among patients with low and higher literacy levels. The final 13-item scale had good internal consistency reliability (Cronbach's alpha = 0.89). A two-factor solution was found, explaining 52.3% of the scale's variance. The scale performed similarly across literacy levels. The SEAMS is a reliable and valid instrument that may provide a valuable assessment of medication self-efficacy in chronic disease management, and appears appropriate for use in patients with low literacy skills.

    Full Text Available BackgroundLiver biopsy is recommended as the gold standard method for assessing the stage of liver fibrosis in patients with chronic liver disease. However, it is invasive, with potential risks and complications. Elastography is an ultrasound technique that provides information of changes in the liver tissue, evaluating tissue elasticity and acoustic radiation force impulse is one of the available techniques.ObjectiveThe main objective of this study was to evaluate the sensitivity and specificity of acoustic radiation force impulse comparing to liver biopsy to evaluate fibrosis in patients with chronic hepatitis C virus and nonalcoholic fatty liver disease.MethodsTwenty four patients were included, everyone underwent liver biopsy and acoustic radiation force impulse, and the results were compared with values described in the literature by several authors.ResultsIn the population of patients with chronic hepatitis C, our data were better correlated with data published by Carmen Fierbinteanu-Braticevici et al., with an accuracy of 82.4%, sensitivity of 71.4% and specificity of 90%. For nonalcoholic fatty liver disease, our data were better correlated with data published by Masato Yoneda et al., with an accuracy of 85.7%, sensitivity 80% and specificity of 100%.ConclusionAcoustic radiation force impulse is a method with good accuracy to distinguish initial fibrosis from advanced fibrosis in hepatitis C virus and nonalcoholic fatty liver disease and can replace biopsy in most cases.

    Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in developed countries and it is now considered a risk factor for cardiovascular disease. Evidence linking NAFLD to the development and progression of chronic kidney disease (CKD) is emerging as a popular area of scientific interest. The rise in simultaneous liver-kidney transplantation as well as the significant cost associated with the presence of chronic kidney disease in the NAFLD population make this entity a worthwhile target for screening and therapeutic intervention. While several cross-sectional and case control studies have been published to substantiate these theories, very little data exists on the underlying cause of NAFLD and CKD. In this review, we will discuss the most recent publications on the diagnosis of NAFLD as well new evidence regarding the pathophysiology of NAFLD and CKD as an inflammatory disorder. These mechanisms include the role of obesity, the renin-angiotensin system, and dysregulation of fructose metabolism and lipogenesis in the development of both disorders. Further investigation of these pathways may lead to novel therapies that aim to target the NAFLD and CKD. However, more prospective studies that include information on both renal and liver histology will be necessary in order to understand the relationship between these diseases.

    The aim of the study was to research the incidence of alimentary risk factors (RF) of chronic noninfectious diseases under severe conditions of complex climatoecologic and biogeochemical factors of the Far North. The representative sample of 2,094 Nadym-city non-Natives (Yamalo-Nenets Autonomous Okrug) aged 20-59 was examined. In the first cross-sectional study, 1,093 persons (39.1% of men and 60.9% of women)--and in the last screening 1,001 persons (33.9% of men and 66.1% of women)--were examined. The RF presence was established on the basis of the following criteria: arterial hypertension (WHO, ISAH (1999)) was defined at blood pressure levels > or = 140-90 mmHg. Persons who finished antihypertensive treatment no later than two weeks before examination were also referred to this group. Excessive body mass for both men and women was defined at Quetlet index > or = 29.0 kg/m2, hypercholesterolemia at plasma cholesterol level > or = .5 mmol/l, hypertriglyceridemia at triglyceride level > or = 2.26 mmol/ l, hypoalphacholesterolemia at high density lipoproteins cholesterol level or = 4.1 mmol/l. The results of research revealed high incidence of alimentary-dependent RF of chronic noninfectious diseases. In six-year dynamics, the increase of dislipoproteidemias for 18.1% (31.3% vs. 26.5%), high incidence of arterial hypertension (31.0% vs. 38.5%), and excessive body mass (33.3% vs. 30.6%) were assessed. High incidence of alimentary-dependent RF of chronic noninfectious diseases is the direct consequence of unsatisfactory, misbalanced nutrition. In programs aimed at prevention of alimentary-dependent diseases the priority should be given to non-pharmacological (or non-medicamentous) methods, and, first of all, to dietologic methods aimed at correcting the nutrition structure in the population.

    2008-06-01

    Studies have shown that most patients diagnosed with chronic Lyme disease either have no objective evidence of previous or current infection with Borrelia burgdorferi or are patients who should be classified as having post-Lyme disease syndrome, which is defined as continuing or relapsing nonspecific symptoms (such as fatigue, musculoskeletal pain, and cognitive complaints) in a patient previously treated for Lyme disease. Despite extensive study, there is currently no clear evidence that post-Lyme disease syndrome is caused by persistent infection with B burgdorferi. Four randomized placebo-controlled studies have shown that antibiotic therapy offers no sustained benefit to patients who have post-Lyme disease syndrome. These studies also showed a substantial placebo effect and a significant risk of treatment-related adverse events. Further research to elucidate the mechanisms underlying persistent symptoms after Lyme disease and controlled trials of new approaches to the treatment and management of these patients are needed.

    A group of patients between 35 and 65 years old with chronic prostatitis were examined for the presence of Becherew's disease. In this connection the New York and Roman criterions for morbus Bechterew were applied. There were found one ankyosing spondylarthritis, one ankylosis of the sacroiliac joint, and 11 times a tentative sacroileitis were stated. Altogether the proved and tentative findings were only 3.68 per cent of all examinations. In our countries the morbus Bechterew is found in 0,21 per cent of the normal population. So the protion of the Bechterew's disease in patients with chronic prostatitis is indeed a little higher than average, but not so frequent as often pretended in recent times. After a second series 58 patients being treated because of Bechterew's disease of different stages and different terms were examined for the possibility of a simultaneously elapsing chronic prostatitis. A chronic prostatitis was found in 38 per cent of these patients which correspondents to the incidence published in literature for the medium-age manhood. Nobody of the test persons had complaints on the part of the urologenital tract.

    2008-07-01

    There is much controversy about the treatment of Lyme disease with respect to 2 poorly defined entities: "chronic Lyme disease" and "posttreatment Lyme disease syndrome." In the absence of direct evidence that these conditions are the result of a persistent infection, some mistakenly advocate extended antibiotic therapy (>/=6 months), which can do great harm and has resulted in at least 1 death. The purpose of this brief report is to review what is known from clinical research about these conditions to assist both practicing physicians and lawmakers in making sound and safe decisions with respect to treatment.

    Children with chronic infectious interstitial lung disease often have to undergo open lung biopsy to establish a final diagnosis. Open lung biopsy is an invasive procedure with major potential complications. Transthoracic lung biopsy (TLB) guided by computed tomography (CT) is a less-invasive well-established procedure in adults. Detailing the role of low-dose CT-guided TLB in the enhanced diagnosis of chronic lung diseases related to infection in children. A group of 11 children (age 8 months to 16 years) underwent CT-guided TLB with a 20-gauge biopsy device. All investigations were done under general anaesthesia on a multidetector CT scanner (SOMATOM Volume Zoom, Siemens, Erlangen, Germany) using a low-dose protocol (single slices, 120 kV, 20 mAs). Specimens were processed by histopathological, bacteriological, and virological techniques. All biopsies were performed without major complications; one child developed a small pneumothorax that resolved spontaneously. A diagnosis could be obtained in 10 of the 11 patients. Biopsy specimens revealed chronic interstitial alveolitis in ten patients. In five patients Chlamydia pneumoniae PCR was positive, in three Mycoplasma pneumoniae PCR was positive, and in two Cytomegalovirus PCR was positive. The average effective dose was 0.83 mSv. Low-dose CT-guided TLB can be a helpful tool in investigating chronic infectious inflammatory processes in children with minimal radiation exposure. It should be considered prior to any open surgical procedure performed for biopsy alone. In our patient group no significant complication occurred. A disadvantage of the method is that it does not allow smaller airways and vessels to be assessed. (orig.)

    In this study, we aimed to compare patients' characteristics, comorbid risk factors, medical supplies, and caregivers' demographics between stroke patients and patients with other chronic neurological diseases receiving home health services. In our study, between November 2013 and March 2014, chronic neurological disease (CND) patients having home health services were enrolled in the study. During patient visits, patients were assessed by the questionnaire comprising the modified Rankin scale (mRS), Barthel index, Zarit caregiver burden scale, and mini nutritional assessment (MNA). Stroke patients were classified as Group I, and the other neurologic diseases as Group II. A total of 202 patients including stroke patients (n = 112), dementia (n = 64), Parkinson's disease (n = 17), motor neuron disease (n = 4), brain cancer (n = 2), cerebral palsy (n = 1), multiple sclerosis (n = 1), and head trauma (n = 1) answered the questionnaire. The mean age of Group I (61K:51E) was 76.6 ± 9.1 years; the Group II (28M:62F) was 80.9 ± 12.3 years. The mean age of Group I was significantly lower than Group II (p = 0.005) and the number of male patients in Group I was significantly higher (p = 0.001). The educational status between the two groups was not significantly different in terms of duration of illness and addiction. There was no difference between the two groups in terms of Zarit caregiver burden scale, Barthel index, and mRS. The presence of malnutrition (MNA nutritional support and providing appropriate nutritional support in other CND patients are expected to increase the life quality.

    Full Text Available It is easier to prevent a disease than to cure it. This postulate is a foundation stone of the contemporary medicine, furthermore its mission. The Chronic Kidney Diseases (CKD, amongst them the Chronic Pyelonephrites (CP and the mass kidney reduction  take an important  place in human pathologies in general, and in particular in renal ones. The Chronic Pyelonephrites  are chronic renal pathologies, which on one side are of various causes and on the other side are multi systemic. At the same time they tend, earlier or later, depending on their course, to bring the patient towards the Chronic Kidney Insufficiency  in stage of uremia, consequently in need of substitution therapies e.g. dialysis, peritoneum dialysis or transplant. It is worthy to emphasize that from the prevention and correct cure of CP make profit the patients, the family, the state and in the last analyses  the entire society, because in that way the budget expense destined for the fore going substitution cures, dialysis, peritoneum dialysis or transplant, is considerably  reduced. The same should be mentioned  in relation to the CP and the mass kidney reduction, speaking about our country, which are still at the first place as the very cause of Chronic Kidney  Insufficiencies (CRI, later on advancing toward uremia and terminal uremia along with its grave consequences. In general  the very foundation of the CP is on  the  infections of urinary roads, in particular on the complicated ones, among them it should be mentioned-congenital kidney anomalies, renal calculosis  so much present in our country, and pathologies of segment or vesical-ureteral reflux, and rarely the pathologies of prostate.

    Wildlife disease transmission, at a local scale, can occur from interactions between infected and susceptible conspecifics or from a contaminated environment. Thus, the degree of spatial overlap and rate of contact among deer is likely to impact both direct and indirect transmission of infectious diseases such chronic wasting disease (CWD) or bovine tuberculosis. We identified a strong relationship between degree of spatial overlap (volume of intersection) and genetic relatedness for female white-tailed deer in Wisconsin's area of highest CWD prevalence. We used volume of intersection as a surrogate for contact rates between deer and concluded that related deer are more likely to have contact, which may drive disease transmission dynamics. In addition, we found that age of deer influences overlap, with fawns exhibiting the highest degree of overlap with other deer. Our results further support the finding that female social groups have higher contact among related deer which can result in transmission of infectious diseases. We suggest that control of large social groups comprised of closely related deer may be an effective strategy in slowing the transmission of infectious pathogens, and CWD in particular.

    This paper explores the economic implications of vouchers for chronic disease management with respect to achieving objectives of equity and efficiency. Vouchers as a payment policy instrument for health care services have a set of properties that suggest they may address both demand-side and supply-side issues, and contribute to equity and efficiency. They provide a means whereby health care services can be targeted at selected groups, enabling consumer choice of provider, and encouraging competition in the supply of health services. This analysis suggests that, when structured appropriately, vouchers can support consumers to choose services that will meet their health care needs and encourage competition among providers. Although they may not be appropriate across the entire health care system, there are features of vouchers that make them a potentially attractive option, especially for the management of chronic disease.

    Full Text Available Background : Human telomerase is a multi subunit ribonucleoprotein enzyme concerned with telomeric lengthening and homeostasis in man. This enzyme has been found to be elevated in inflammatory conditions like rheumatoid arthritis and silica injury lung. Since chronic periodontitis is also an inflammatory condition where immune cells and cytokines mediate tissue destruction, we set out to evaluate telomerase in gingival tissue samples from healthy subjects and chronic periodontitis patients by reverse transcriptase polymerase chain reaction. Materials and Methods : Gingival biopsies were obtained from eight healthy subjects and eight chronic periodontitis patients. Reverse transcriptase polymerase chain reaction (RTPCR was carried out to evaluate telomerase gene expression in the samples. Results : None of the healthy gingival tissue samples expressed the telomerase gene while all the chronic periodontitis samples expressed it. The severe chronic periodontitis samples expressed the gene more intensely than the moderate chronic periodontitis samples. Conclusion : Various mechanisms have been explained to account for telomerase elevation in chronic periodontitis .This study helps us understand the role of telomerase in the pathogenesis of periodontal disease. It could be concluded that telomerase could be used as a marker to assess the severity of inflammation in chronic periodontitis.

    Full Text Available Abstract Background Childhood chronic disease may affect patients' and their family's functioning. Particularly parents, who play an important role in cooperation between patient and health care professionals, report impaired health - related quality of life (HRQOL. The aim of this study was development, evaluation and validation of a new instrument: Quality of Life in a Child's Chronic Disease Questionnaire (QLCCDQ. The questionnaire is addressed to parents of children with a chronic disease. Methods Study design included semi structured interview and qualitative study, which allowed to identify most troublesome problems. Following the results the questionnaire was developed, which consists of 15 questions and covers domains - emotions, patients -perceived symptoms, roles limitations. An observational study involving parents of asthma and diabetes children was conducted to assess the psychometric characteristics of the measure. Psychometric testing was based on the reliability of defined subscales, construct validity, reproducibility assessment, as well as comparison between stable/unstable disease stages and parents of healthy children. Results Most troublesome concerns for parents of child with chronic disease included emotional distress and feeling depressed due to child's disease, avoiding social interactions due to child's disease or symptoms. 98 parents of children with asthma or insulin - depended diabetes participated in the psychometric testing of QLCCDQ. Internal consistency reliability for the defined subscales ranged between 0.77 and 0.93. Reproducibility based on the weighted kappa coefficients showed expected level of agreement and was almost perfect in case of 8 questions, substantial for 5 questions and moderate for 2 questions. QLCCDQ demonstrated very good construct validity - all subscales showed statistically significant correlations ranging from 0.4 to 0.9.

    Full Text Available Abstract Background Public health promotes an ecological approach to chronic disease prevention, however, little research has been conducted to assess the integration of an ecological approach in community-based prevention programs. This study sought to contribute to the evidence base by assessing the extent to which an ecological approach was integrated into an Aboriginal community-based cardiovascular disease (CVD and type 2 diabetes prevention program, across three-intervention years. Methods Activity implementation forms were completed by interview with implementers and participant observation across three intervention years. A standardised ecological coding procedure was applied to assess participant recruitment settings, intervention targets, intervention strategy types, extent of ecologicalness and organisational partnering. Inter-rater reliability for two coders was assessed at Kappa = 0.76 (p Results 215 activities were implemented across three intervention years by the health program (HP with some activities implemented in multiple years. Participants were recruited most frequently through organisational settings in years 1 and 2, and organisational and community settings in year 3. The most commonly utilised intervention targets were the individual (IND as a direct target, and interpersonal (INT and organisational (ORG environments as indirect targets; policy (POL, and community (COM were targeted least. Direct (HP→ IND and indirect intervention strategies (i.e., HP→ INT→ IND, HP→ POL → IND were used most often; networking strategies, which link at least two targets (i.e., HP→[ORG-ORG]→IND, were used the least. The program did not become more ecological over time.

    Radionuclide angiography permits evaluation of left ventricular performance during exercise. There are several factors that may affect the results in normal subjects and in patients with chronic coronary heart disease. Important among these are the selection criteria: age, sex, level of exercise, exercise end points, ejection fraction at rest and effects of pharmacologic agents. An abnormal ejection fraction response to exercise is not a specific marker for coronary heart disease but may be encountered in other cardiac diseases. In addition to the diagnostic considerations, important prognostic data can be obtained. Further studies are needed to determine the prognostic implications of anatomic findings versus the functional abnormalities induced by exercise in patients with coronary artery disease.

    The clinical practice guidelines for the prevention, diagnosis, evaluation and treatment of chronic kidney disease mineral and bone disorders (CKD-BMD) in adults, of the Latin American Society of Nephrology and Hypertension (SLANH) comprise a set of recommendations developed to support the doctor in the management of these abnormalities in adult patients with stages 3-5 kidney disease. This excludes changes associated with renal transplantation. The topics covered in the guidelines are divided into four chapters: 1) Evaluation of biochemical changes, 2) Evaluation of bone changes, 3) Evaluation of vascular calcifications, and 4) Treatment of CKD-MBD. The guidelines are based on the recommendations proposed and published by the Kidney Disease: Improving Global Outcomes (KDIGO) for the prevention, diagnosis, evaluation and treatment of CKD-MBD (KDIGO Clinical practice guidelines for the diagnosis, evaluation, prevention and treatment of Chronic Kidney Disease Mineral and Bone Disorder [CKD-MBD]), adapted to the conditions of patients, institutions and resources available in Latin America, with the support of KDIGO. In some cases, the guidelines correspond to management recommendations directly defined by the working group for their implementation in our region, based on the evidence available in the literature. Each chapter contains guidelines and their rationale, supported by numerous updated references. Unfortunately, there are few controlled studies with statistically sufficient weight in Latin America to support specific recommendations for the region, and as such, most of the references used correspond to studies carried out in other regions. This highlights the need to plan research studies designed to establish the current status of mineral and bone metabolism disorders in Latin America as well as defining the best treatment options for our population.

    2002-09-01

    Lyme disease is currently the most common vector-borne illness in the United States. The disease is multisystemic, and chronic disease, in particular, may be associated with neuropsychological deficits. However, to date, only a few empirical studies exist, which examine the neuropsychological sequelae associated with chronic Lyme disease. A review of the literature shows that the deficits observed in adults with chronic Lyme disease are generally consistent with the deficits that can be seen in processes with primarily frontal systems involvement. These observations are generally consistent with neuroradiologic findings. The clinical presentation in chronic Lyme disease and the nature of the neuropsychological deficits are discussed, as are several central issues in understanding neuropsychological functioning in chronic Lyme disease, such as the impact of chronic illness, response to treatment, and the relationship between neuropsychological performance and depression, fatigue, and neurological indicators of disease.

    Propranolol is known to decrease portal pressure by reducing blood flow of portal vein. Per-rectal portal scintigraphy with Tc-99m pertechnetate has been introduced to evaluate the portal circulation and early diagnosis of liver cirrhosis. We evaluated the effects of propranolol on portal circulation by using per-rectal portal scintigraphy. We analyzed the portal hemodynamics by per-rectal portal scintigraphy in 51 patients with liver cirrhosis, 10 chronic hepatitis and 10 normal subjects. 38 patients with cirrhosis underwent per-rectal portal scintigraphy before and after propranolol medication. Per-rectal portal scintigraphy was performed after per-rectal administration of 370 MBq of Tc-99m pertechnetate. The shunt index was calculated as the ratio, expressed as a percentage of heart radioactivity to the sum of heart and liver radioactivity during the first 30 seconds. The shunt index in 40 patients with cirrhosis (59.8{+-}27.2%) was significantly higher than that of normal control (5.0{+-}1.2%, p<0.01) and chronic hepatitis (11.4{+-}3.5%, p<0.01). Shunt index was significantly different according to Child's classification and the degree of esophgageal varix (p<0.01). After propranolol medication, shunt index was significantly decreased from 59.9{+-}27.3% to 51.3{+-}15.3% (p<0.01) in 38 patients with liver cirrhosis. There was no significant difference of the amount of shunt index reduction after propranolol according to Child's classification and the degree of esophageal varix. The effect of propranolol on portal circulation was demonstrated as decreasing shunt index on per-rectal portal scintigraphy in patients with liver cirrhosis. Per-rectal portal scintigraphy may be useful to evaluate the portal circulation and to predict the effect of propranolol in patients with liver cirrhosis.

    Currently, non-communicable chronic diseases are a major cause of morbidity and mortality worldwide, and a large proportion of chronic diseases are preventable through risk factor management. However, the prevention efficacy at the individual level is not yet satisfactory. Chronic disease prediction models have been developed to assist physicians and individuals in clinical decision-making. A chronic disease prediction model assesses multiple risk factors together and estimates an absolute disease risk for the individual. Accurate prediction of an individual's future risk for a certain disease enables the comparison of benefits and risks of treatment, the costs of alternative prevention strategies, and selection of the most efficient strategy for the individual. A large number of chronic disease prediction models, especially targeting cardiovascular diseases and cancers, have been suggested, and some of them have been adopted in the clinical practice guidelines and recommendations of many countries. Although few chronic disease prediction tools have been suggested in the Korean population, their clinical utility is not as high as expected. This article reviews methodologies that are commonly used for developing and evaluating a chronic disease prediction model and discusses the current status of chronic disease prediction in Korea.

    Full Text Available The incidence and prevalence of congestive heart failure are actually increasing worldwide, especially in Western countries. In Europe and the United States, congestive heart failure represents a disabling clinical disease, accountable for increased hospitalization and health care costs. European guidelines have underlined the importance of pharmacological treatment to improve both patients’ outcomes and quality of life. The latest clinical trials to evaluate ivabradine’s efficacy have underlined its usefulness as a stand-alone medication and in combination with conventional congestive heart failure therapy, including in chronic kidney disease patients.

    Chronic kidney disease (CKD) is a frequent complication of HIV infection, occurring in 3.5 - 48.5%, and occurs as a complication of HIV infection, other co-morbid disease and infections and as a consequence of therapy of HIV infection and its complications. The classic involvement of the kidney by HIV infection is HIV-associated nephropathy (HIVAN), occurring typically in young adults of African ancestry with advanced HIV disease in association with APOL1 high-risk variants. HIV-immune complex disease is the second most common diagnosis obtained from biopsies of patients with HIV-CKD. CKD is mediated by factors related to the virus, host genetic predisposition and environmental factors. The host response to HIV infection may influence disease phenotype through activation of cytokine pathways. With the introduction of antiretroviral therapy (ART), there has been a decline in the incidence of HIVAN, with an increasing prevalence of focal segmental glomerulosclerosis. Several studies have demonstrated the overall improvement in kidney function when initiating ART for HIV CKD. Progression to end stage kidney disease has been reported to be more likely when high grade proteinuria, severely reduced eGFR, hepatitis B and/C co-infection, diabetes mellitus, extensive glomerulosclerosis, and chronic interstitial fibrosis are present. Improved renal survival is associated with use of renin angiotensin system blockers and viral suppression. Many antiretroviral medications are partially or completely eliminated by the kidney and require dose adjustment in CKD. Certain drug classes, such as the protease inhibitors and the non-nucleoside reverse transcriptase inhibitors, are metabolized by the liver and do not require dose adjustment. HIV-infected patients requiring either hemo- or peritoneal dialysis, who are stable on ART, are achieving survival rates comparable to those of dialysis patients without HIV infection. Kidney transplantation has been performed successfully in HIV

    The aim of this study was to identify useful predictors of cardiac events in patients with chronic kidney disease (CKD). Among 4,031 patients identified from the Japanese Assessment of Cardiac Events and Survival Study (J-ACCESS) database with suspected or known ischaemic heart disease, we selected 820 with an estimated glomerular filtration rate (eGFR) of < 60 ml/min per 1.73 m{sup 2}. A total of 75 cardiac events developed among these 820 patients. The incidence of cardiac events was higher in the group with a lower eGFR. Multivariate Cox analysis indicated that age, diabetes mellitus, end-systolic volume, summed stress score (SSS) and eGFR were predictors of cardiac events. Event rates of patients with SSS {>=} 9 were significantly higher in groups with lower eGFR values (< 40 and 40-49 ml/min). The SSS value ({>=} 9) is a reliable predictor of cardiac events and myocardial single photon emission computed tomography has incremental value for predicting cardiac events and survival in CKD.

    Full Text Available A worldwide epidemic of chronic disease, and complications thereof, is underway, with no sign of abatement. Healthcare costs have increased tremendously, principally because of the need to treat chronic complications of non-communicable diseases including cardiovascular disease, blindness, end-stage renal disease, and amputation of extremities. Current healthcare systems fail to provide an appropriate quality of care to prevent the development of chronic complications without additional healthcare costs. A new paradigm for prevention and treatment of chronic disease and the complications thereof is urgently required. Several clinical studies have clearly shown that frequent communication between physicians and patients, based on electronic data transmission from medical devices, greatly assists in the management of chronic disease. However, for various reasons, these advantages have not translated effectively into real clinical practice. In the present review, we describe current relevant studies, and trends in the use of information technology for chronic disease management. We also discuss limitations and future directions.

    The pathogenetic mechanisms of anemia in patients with chronic liver disease were observed. Seventeen patients with moderate to advanced hepatic diseases were studied by various methods. Only patients without previous blood loss were included : 14 had cirrhosis, 2 had active chronic hepatitis, and one had inferior vena cava obstruction with associated liver cirrhosis. The followings were the results: 1. The anemia based on red blood cell count, Hb., and Ht. was found in 76.5-78.6% of the patients. 2. Red cell indices indicated that normo-macrocytic and normochromic anemia was present is the majority of the patients. 3. No evidence of megaloblastic anemia was found on the basis of the morphological examinations. 4. Serum iron, TIBC, % saturation and iron content in the bone marrow indicated that iron deficiency anemia was present in about half of the patients. 5. In the view of the erythrocyte dynamics, primary increase in the red cell destruction was ascribed to the cause of the anemia. 6. Decrease in the red cell survival time was not correlated with MCV, % saturation and S.L. ratio. Also, hemoglobin level was not correlated with MCV, % saturation and T{sub 50} Cr. Therefore, multiple causes may be involved in the pathogenesis of the anemia. 7. Anemia as determined by the red cell volume was found in only 60% of the patients. It may be possible that hemodilutional anemia is present.

The purpose of this study was to describe the IPA patient with chronic lung disease and compare the data with that of immunocompromised patients.Methods: The records of 351 patients with Aspergillus were evaluated in this single-center, retrospective study for evidence and outcomes of IPA. The outcomes of 57 patients with chronic lung disease and 56 immunocompromised patients were compared. Patients with chronic lung disease were defined by one of the following descriptive terms: emphysema, asthma, idiopathic lung disease, bronchitis, bronchiectasis, sarcoid, or pulmonary leukostasis.Results: Baseline demographics were similar between the two groups. Patients with chronic lung disease were primarily defined by emphysema (61% and asthma (18%, and immunocompromised patients primarily had malignancies (27% and bone marrow transplants (14%. A higher proportion of patients with chronic lung disease had a diagnosis of IPA by bronchoalveolar lavage versus the immunocompromised group (P < 0.03. The major risk factors for IPA were found to be steroid use in the chronic lung disease group and neutropenia and prior surgical procedures in the immunocompromised group. Overall, 53% and 69% of chronic lung disease and immunocompromised patients were cured (P = 0.14; 55% of chronic lung patients and 47% of immunocompromised patients survived one month (P = 0.75.Conclusion: Nontraditional patients with IPA, such as those with chronic lung disease, have outcomes and mortality similar to that in the

    Background Toxoplasma gondii has worldwide distribution and is one of the most prevalent infectious agents in humans. Objectives The aim of this study was to determine the prevalence of anti-Toxoplasma gondii antibodies in hemodialysis patients with chronic kidney disease (CKD) in the hemodialysis unit of Fatemeh Zahra hospital at the Mazandaran University of Medical Sciences in Sari, Iran. Methods Seventy-three patients with CKD and 145 healthy volunteers were assessed for anti-Toxoplasma gondii (IgG, IgM, and IgA) antibodies using a conventional ELISA technique. Results The anti-Toxoplasma gondii IgG antibody was detected in 80.8% of the cases in the patient group, while 31.5% of the cases in the CKD patient group and 31.8% in the control group were found to be positive for the anti-Toxoplasma gondii IgA antibody. All the patients in the CKD group were negative for the anti-Toxoplasma gondii IgM antibody, although 2.76% of the healthy volunteers were found to be positive. The present study suggests that there was no significant difference between the hemodialysis patient group and the healthy volunteers. Conclusions The epidemiological data collected in this study could serve as a reference for future studies and may be useful in developing preventive and educational strategies, and consequently reducing healthcare expenditure.

    Full Text Available Background. Acute kidney injury (AKI is a common complication of cardiac surgery but its long-term consequences, in patients with chronic kidney disease (CKD, are not known. Methods. We compared the long-term prognoses of CKD patients who developed (n=23 and did not develop (n=35 AKI during the period of hospitalization after undergoing coronary artery bypass graft (CABG. Fifty-eight patients who survived (69.6±8.4 years old, 72% males, 83% Whites, 52% diabetics, baseline GFR: 46±16 mL/min were followed up for 47.8±16.4 months and treated for secondary prevention of events. Results. There were 6 deaths, 4 in the AKI+ and 2 in the AKI− group (Log-rank = 0.218, two attributed to CV causes. At the end of the study, renal function was similar in the two groups. One AKI− patient was started on dialysis. Only 4 patients had an increase in serum creatinine ≥ 0.5 mg/dL during follow-up. Conclusion. CKD patients developing AKI that survived the early perioperative period of coronary intervention present good renal and nonrenal long-term prognosis, compared to patients who did not develop AKI.

    We report the case of a 53 year old man with a chronic periaortitis (CP) in whom Fluorine 18 Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) has been useful in assessing the disease extent at diagnosis, in evaluating the treatment response, in diagnosing the relapse, and in monitoring the disease activity during follow up. This case highlights the usefulness of FDG PET/CT at different times in patients with CP. CP is a rare inflammatory disorder that affects the abdominal aorta and the retroperitoneum. Imaging procedures are essential to diagnose and monitor the disease course. Ultrasonography may be used as first line screening test, and is particularly useful to monitor patients with hydronephrosis and aortic aneurysms. However, CT or magnetic resonance imaging (MRI) of the abdomen are currently considered the investigations of choice to diagnose CP. In active CP, the periaortic mass usually enhances on CT and MRI. Both these methods can be used to monitor the disease course of CP and to evaluate response to treatment. A note of caution: signs of vasculitis seen on MRI and CT may persist for some time, despite achievement of clinical remission. A further limitation of abdominal CT and MRI is that neither technique can detect vasculitis in vessels other than the abdominal aorta, which has been described in 43% of patients with CP. FDG PET/CT has been proposed as useful tool in inflammatory diseases, such as aortitis, because metabolic changes assessed by FDG PET/CT usually precede morphological changes assessed by conventional imaging methods. Our case highlights the usefulness of FDG PET/CT at different times in patients with CP. This method may be useful in assessing disease activity and extent at diagnosis, in evaluating the treatment response, in diagnosing the relapse, and in monitoring the disease during follow up.

  11. Chronic Kidney Disease and Endothelium

    2015-07-01

    Full Text Available The endothelial cell layer is responsible for molecular traffic between the blood and surrounding tissue, and endothelial integrity plays a pivotal role in many aspects of vascular function. Cardiovascular disease (CVD is the main cause of death in patients with chronic kidney disease (CKD and its incidence and severity increase in direct proportion with kidney function decline. Non-traditional risk factors for CVDs, including endothelial dysfunction (ED, are highly prevalent in this population and play an important role in cardiovascular (CV events. ED is the first step in the development of atherosclerosis and its severity has prognostic value for CV events. Several risk markers have been associated with ED. Reduced bioavailability of nitric oxide plays a central role, linking kidney disease to ED, atherosclerosis, and CV events. Inflammation, loss of residual renal function, and insulin resistance are closely related to ED in CKD. ED may be followed by structural damage and remodelling that can precipitate both bleeding and thrombotic events. The endothelium plays a main role in vascular tone and metabolic pathways. ED is the first, yet potentially reversible step in the development of atherosclerosis and its severity has prognostic value for CV events.

    Numerous lines of evidence implicate a role of myeloperoxidase (MPO) in the pathogenesis of cardiovascular disease (CVD). It is a well accepted fact that patients with chronic kidney disease (CKD) are at an increased risk for CVD. MPO is a pro-oxidant enzyme which could be involved in the increased susceptibility of these patients to CVD. Hence, the levels of plasma MPO was determined in healthy controls as well as in patients with CKD [stratified with the level of their kidney failure as CKD stages II-V (end stage renal disease)]. Plasma MPO was assayed by a spectrophotometric method. Serum urea and creatinine were estimated on a clinical chemistry analyzer using standard laboratory procedures. The mean plasma MPO levels were significantly lower with advancing stages of renal failure (P < 0.001). There was a positive correlation between MPO and GFR (r = +0.89, P < 0.001) and a negative correlation with urea (r = -0.85, P < 0.001) and creatinine (r = -0.82, P < 0.001). While an inverse association was observed between plasma MPO and urea in CKD patients, such an association was not observed in control subjects (P = 0.43). In conclusion, the decline in plasma MPO levels may be due to the inhibitory effect of uraemic toxins on the enzyme.

  13. Analysis of electrocardiogram in chronic obstructive pulmonary disease patients

    Full Text Available Introduction. Chronic obstructive pulmonary disease is the fourth leading cause of mortality worldwide. It is defined as a persistent airflow limitation usually progressive and not fully reversible to treatment. The diagnosis of chronic obstructive pulmonary disease and severity of disease is confirmed by spirometry. Chronic obstructive pulmonary disease produces electrical changes in the heart which shows characteristic electrocardiogram pattern. The aim of this study was to observe and evaluate diagnostic values of electrocardiogram changes in chronic obstructive pulmonary disease patients with no other comorbidity. Material and Methods. We analyzed 110 electrocardiogram findings in clinically stable chronic obstructive pulmonary disease patients and evaluated the forced expiratory volume in the first second, ratio of forces expiratory volume in the first second to the fixed vital capacity, chest radiographs and electrocardiogram changes such as p wave height, QRS axis and voltage, right bundle branch block, left bundle branch block, right ventricular hypertrophy, T wave inversion in leads V1-V3, S1S2S3 syndrome, transition zone in praecordial lead and QT interval. Results. We found electrocardiogram changes in 64% patients, while 36% had normal electrocardiogram. The most frequent electrocardiogram changes observed were transition zone (76.36% low QRS (50% and p pulmonale (14.54%. Left axis deviation was observed in 27.27% patients. Conclusion. Diagnostic values of electrocardiogram in patients with chronic obstructive pulmonary disease suggest that chronic obstructive pulmonary disease patients should be screened electrocardiographically in addition to other clinical investigations.

    Acute kidney injury (AKI),defined as an abrupt increase in the serum creatinine level by at least 0.3 mg/dL,occurs in about 20% of patients hospitalized for decompensating liver cirrhosis.Patients with cirrhosis are susceptible to developing AKI because of the progressive vasodilatory state,reduced effective blood volume and stimulation of vasoconstrictor hormones.The most common causes of AKI in cirrhosis are pre-renal azotemia,hepatorenal syndrome and acute tubular necrosis.Differential diagnosis is based on analysis of circumstances of AKI development,natriuresis,urine osmolality,response to withdrawal of diuretics and volume repletion,and rarely on renal biopsy.Chronic glomeruIonephritis and obstructive uropathy are rare causes of azotemia in cirrhotic patients.AKI is one of the last events in the natural history of chronic liver disease,therefore,such patients should have an expedited referral for liver transplantation.Hepatorenal syndrome (HRS) is initiated by progressive portal hypertension,and may be prematurely triggered by bacterial infections,nonbacterial systemic inflammatory reactions,excessive diuresis,gastrointestinal hemorrhage,diarrhea or nephrotoxic agents.Each type of renal disease has a specific treatment approach ranging from repletion of the vascular system to renal replacement therapy.The treatment of choice in type 1 hepatorenal syndrome is a combination of vasoconstrictor with albumin infusion,which is effective in about 50% of patients.The second-line treatment of HRS involves a transjugular intrahepatic portosystemic shunt,renal vasoprotection or systems of artificial liver support.

    Full Text Available OBJECTIVE: To determine the impact of periodontal treatment on serum levels of prohepcidin (the prohormone of hepcidin and systemic inflammation markers, as well as correlations among these markers, in patients with chronic periodontitis and chronic kidney disease who were not undergoing dialysis. METHODS: We included 56 chronic periodontitis patients, 36 with chronic kidney disease and 20 without systemic diseases and with normal renal function (control group. Chronic kidney disease was defined as suggested by the clinical practice guidelines in the National Kidney Foundation. Chronic periodontitis was defined through clinical attachment level and by probing pocket depth, according to the American Association of Periodontology. The inflammatory markers ultrasensitive C-reactive protein, interleukin-6, and prohepcidin were evaluated before and 3 months after periodontal treatment. RESULTS: The efficacy of periodontal treatment was confirmed by the improvement in clinical parameters of chronic periodontitis in the control and chronic kidney disease groups. Periodontal treatment resulted in significant reductions in ultrasensitive C-reactive protein, interleukin-6 and serum prohepcidin levels in both groups. Moreover, in multivariate linear regression, the reduction in prohepcidin after periodontal treatment was significantly and independently associated with interleukin-6 levels in the control group. CONCLUSIONS: By inducing a decline in the systemic inflammatory response and a decrease in serum prohepcidin, successful periodontal treatment may represent an important means of ameliorating the inflammatory burden seen in patients with chronic kidney disease.

    Probiotics are the focus of a thorough investigation as a natural biotreatment due to their various health-promoting effects and inherent ability to fight specific diseases including chronic kidney disease (CKD). Indeed, intestinal microbiota has recently emerged as an important player in the progression and complications of CKD. Because many of the multifactorial physiological functions of probiotics are highly strain specific, preselection of appropriate probiotic strains based on their expression of functional biomarkers is critical. The interest in developing new research initiatives on probiotics in CKD have increased over the last decade with the goal of fully exploring their therapeutic potentials. The efficacy of probiotics to decrease uremic toxin production and to improve renal function has been investigated in in vitro models and in various animal and human CKD studies. However to date, the quality of intervention trials investigating this novel CKD therapy is still lacking. This review outlines potential mechanisms of action and efficacy of probiotics as a new CKD management tool, with a particular emphasis on uremic toxin production and inflammation.

  19. Respiratory Conditions Update: Chronic Obstructive Pulmonary Disease.

    Chronic obstructive pulmonary disease (COPD) is defined as persistent airflow limitation due to irritant-induced chronic inflammation. A postbronchodilator forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC) ratio of 0.7 or less is diagnostic in a patient with dyspnea, chronic cough or sputum production, and a history of irritant exposure. Tobacco smoking is the most significant etiology, and smoking cessation is the only intervention shown to slow disease progression. Long-acting beta2-agonists and long-acting muscarinic antagonists are first-line treatments for patients with persistently symptomatic COPD with an FEV1 of 80% or less of predicted. When COPD is uncontrolled with a long-acting bronchodilator, combination therapy with a long-acting muscarinic antagonist-long-acting beta2-agonist or long-acting beta2-agonist-inhaled corticosteroid should be prescribed. Patients with COPD and reduced exercise tolerance should undergo pulmonary rehabilitation and be evaluated for supplemental oxygen therapy. Other treatment options for persistently symptomatic COPD include inhaler triple therapy (ie, long-acting muscarinic antagonist, long-acting beta2-agonist, inhaled corticosteroid), phosphodiesterase type 4 inhibitors, oxygen, and surgical interventions.

    Introduction Peripherally inserted central venous catheters (PICCs) may adversely impact future successful arteriovenous fistulae (AVF). As part of a quality improvement project, the performance of tunneled small bore tunneled central venous catheters (TSB-CVCs), as alternatives to PICCs, was evaluated. Methods A retrospective observational study, involving individuals ≥18 years of age who underwent TSB-CVC placement by Interventional Radiology at Mayo Clinic, Rochester, MN between 1/1/2010 and 8/30/2013. Findings The study cohort included 92 patients with a median age of 55 (46-67) years, who underwent 108 TSB-CVC placements. Baseline renal disease was present in 71% (77/108). Most TSB-CVCs were placed in hospitalized patients (94%; 102/108); five French in diameter (61%; 66/108) and located in an internal jugular vein (84%; 91/108). Median catheter indwelling time was 20 (11-43) days (n = 84). TSB-CVC-related bloodstream infection, deep venous thrombosis (DVT), and superficial venous thrombosis (SpVT) rates per line were 0.009 (1/108), 0.018 (2/108), and 0.009 (1/108), respectively. Venous outcomes in a subgroup of 54 patients, who had documented PICC placements (n = 161) in addition to TSB-CVC (n = 58) were compared. TSB-CVC-DVT rate was lower than the PICC-DVT rate (0.017 [1/58] vs. 0.106 per line [17/161]; P = 0.04). The TSB-CVC-SpVT rate was not different from the PICC-SpVT rate (0 [0/58] vs. 0.037 [6/161] per line; P = 0.14). Discussion TSB-CVCs demonstrated an excellent safety profile in our study. These catheters should be preferentially utilized for arm vein preservation in advanced kidney disease. Their impact on future AVF success needs further evaluation.

    Purpose: To determine the frequency of inappropriate inhaled corticosteroid (ICS) therapy when it is prescribed concurrently with systemic corticosteroids; to identify cost-savings potential in the setting of chronic obstructive pulmonary disease (COPD) exacerbations. Methods: Patients admitted to 1 of 8 hospital locations utilizing an integrated electronic health record within the health system for COPD exacerbations treated with systemic corticosteroids (equivalent to at least 30 mg of oral prednisone) between July 1, 2013 and June 30, 2014 were included in a retrospective chart review. Endpoints assessed included number of ICS, with or without long-acting beta-2 agonists (LABA), respiratory medications potentially wasted due to overlap therapy with systemic corticosteroids, as well as overall cost attributed to drug product, administration products, and respiratory therapy labor cost from potentially inappropriate overlap therapy. Results were extrapolated based on the number of admissions within the specified time period. Length of stay data were also compared between the 2 groups (overlap therapy vs no overlap therapy) to determine whether overlap therapy results in a reduction of hospital stay. Results: A total of 10,710 admissions were identified and 74 charts were randomly identified for review. Forty-six (62%) patients received at least one dose of overlapping ICS or ICS/LABA. One hundred forty-two nebulized budesonide vials were wasted along with 43 ICS or ICS/LABA inhalers. A total cost of $8,152.75 was attributed to drug product, administration products, and labor cost. Extrapolating to the 10,710 admissions identified, there would potentially be 20,551 wasted budesonide vials and 6,223 wasted ICS or ICS/LABA inhalers, resulting in an estimated annual cost savings of $1,180,090.03 for the health system. Additionally, length of stay was shorter in the group not receiving overlap therapy compared to the group receiving overlap therapy, but it was not

Existing studies conducted in South Africa have demonstrated that people living with NCD rely on traditional herbal medicine (THM primarily or in combination with conventional drugs. The primary research focus has been on the clinical and experimental aspects of THM use for NCD, with limited data on the economic impact of health care delivery. Therefore, the purpose of this study will be to determine the cost and utilization of resources on THM in South Africa for NCD. Materials and methods: Study describes the methods toward incorporating cost estimations and economic evaluation illustrated with the Prospective Urban and rural Epidemiological (PURE study in South Africa. The South African PURE cohort is investigating the geographic and socioeconomic influence of THM spending and utilization, variations in spending based on perceived health status, marital status, and whether spending patterns have any impact on hospitalizations and disability. Data collection and evaluation plan: Since the individual costs of THM are not regulated nor do they have a standardized price value, information obtained through this study can be utilized to assess differences and determine underlying factors contributing to spending. This insight into THM spending patterns can aid in the development and implementation of guidelines or standardized legislation governing THM use and distribution. An economic evaluation and cost estimation model has been proposed, while the data collection is still ongoing

    Full Text Available OBJECTIVE: This study investigated the correlation between the albumin-to-creatinine ratio in the urine and 24-hour urine proteinuria and whether the ratio can predict chronic kidney disease progression even more reliably than 24-hour proteinuria can, particularly in primary IgA nephropathy. METHODS: A total of 182 patients with primary IgA nephropathy were evaluated. Their mean urine albumin-to-creatinine ratio and 24-hour proteinuria were determined during hospitalization. Blood samples were also analyzed. Follow-up data were recorded for 44 patients. A cross-sectional study was then conducted to test the correlation between these parameters and their associations with chronic kidney disease complications. Subsequently, a canonical correlation analysis was employed to assess the correlation between baseline proteinuria and parameters of the Oxford classification. Finally, a prospective observational study was performed to evaluate the association between proteinuria and clinical outcomes. Our study is registered in the Chinese Clinical Trial Registry, and the registration number is ChiCTR-OCH-14005137. RESULTS: A strong correlation (r=0.81, p<0.001 was found between the ratio and 24-hour proteinuria except in chronic kidney disease stage 5. First-morning urine albumin-to-creatinine ratios of ≥125.15, 154.44 and 760.31 mg/g reliably predicted equivalent 24-hour proteinuria ‘thresholds’ of ≥0.15, 0.3 and 1.0 g/24 h, respectively. In continuous analyses, the albumin-to-creatinine ratio was significantly associated with anemia, acidosis, hypoalbuminemia, hyperphosphatemia, hyperkalemia, hypercholesterolemia and higher serum cystatin C. However, higher 24-hour proteinuria was only associated with hypoalbuminemia and hypercholesterolemia. Higher tubular atrophy and interstitial fibrosis scores were also associated with a greater albumin-to-creatinine ratio, as observed in the canonical correlation analysis. Finally, the albumin

    Background Type 2 Diabetes Mellitus is one of the most disabling chronic conditions worldwide, resulting in significant human, social and economic costs and placing huge demands on health care systems. The Inala Chronic Disease Management Service aims to improve the efficiency and effectiveness of care for patients with type 2 diabetes who have been referred by their general practitioner to a specialist diabetes outpatient clinic. Care is provided by a multidisciplinary, integrated team consisting of an endocrinologist, diabetes nurse educators, General Practitioner Clinical Fellows (general practitioners who have undertaken focussed post-graduate training in complex diabetes care), and allied health personnel (a dietitian, podiatrist and psychologist). Methods/Design Using a geographical control, this evaluation study tests the impact of this model of diabetes care provided by the service on patient outcomes compared to usual care provided at the specialist diabetes outpatient clinic. Data collection at baseline, 6 and 12-months will compare the primary outcome (glycaemic control) and secondary outcomes (serum lipid profile, blood pressure, physical activity, smoking status, quality of life, diabetes self-efficacy and cost-effectiveness). Discussion This model of diabetes care combines the patient focus and holistic care valued by the primary care sector with the specialised knowledge and skills of hospital diabetes care. Our study will provide empirical evidence about the clinical effectiveness of this model of care. Trial registration Australian New Zealand Clinical Trials Registry ACTRN12608000010392.

    HIV/AIDS has always been one of the most thoroughly global of diseases. In the era of widely available anti-retroviral therapy (ART), it is also commonly recognised as a chronic disease that can be successfully managed on a long-term basis. This article examines the chronic character of the HIV/AIDS pandemic and highlights some of the changes we might expect to see at the global level as HIV is increasingly normalised as "just another chronic disease". The article also addresses the use of this language of chronicity to interpret the HIV/AIDS pandemic and calls into question some of the consequences of an uncritical acceptance of concepts of chronicity.

    Female sexual dysfunction (FSD) is a multifactorial set of conditions associated with multiple anatomical, physiological, biological, medical and psychological factors that can have major impact on self-esteem, quality of life, mood and relationships. Studies indicate that FSD is commonly seen in women who report a low level of satisfaction with partner relationship and in women with male partners who have erectile dysfunction. This complexity of FSD is augmented by the presence of chronic disease. Negative sexual effects are widely reported in studies of women with chronic diseases (such as metabolic syndrome, diabetes mellitus, chronic kidney disease, cancer, spinal cord injury, lupus, rheumatic diseases, Parkinson's disease, fibromyalgia and chronic pain) as compared to a general healthy female population. Physical problems, emotional problems and partnership difficulties arising from disease-related stress contribute to less active and less enjoyable sex life. Chronic pain, fatigue, low self-esteem as well as use of medications might reduce sexual function. These effects of chronic diseases on female sexual function still remain largely unstudied. The study by Manor and Zohar published in this issue of Harefuah draws our attention to the sexual dysfunction of women with breast cancer and examines their needs for information regarding their sexual function. In the absence of definite treatment evidence, psychological counseling, improved vaginal lubrication, low dose of hormonal therapy can be used to relieve FSD. Physicians must consider integrating diagnosis of their female patients' sexual needs and dysfunction, especially women with chronic diseases. Patients' education and counseling may contribute to a better quality of life in spite of their chronic disease.

    The risk of chronic obstructive pulmonary disease (COPD), as well as thyroid diseases increases with age. COPD is a common systemic disease associated with chronic inflammation. Many endocrinological disorders, including thyroid gland diseases are related to systemic inflammation. Epidemiological studies suggest that patients with COPD are at higher risk of thyroid disorders. These associations are not well-studied and thyroid gland diseases are not included on the broadly acknowledged list of COPD comorbidities. They may seriously handicap quality of life of COPD patients. Unfortunately, the diagnosis may be difficult, as many signs are masked by the symptoms of the index disease. The comprehension of the correlation between thyroid gland disorders and COPD may contribute to better care of patients. In this review, we attempt to revise available literature describing existing links between COPD and thyroid diseases.

    Achilleos, Andreas

    2016-09-01

    Chronic cough is common and has a significant impact on the wellbeing of patients and the use and cost of health care services. Traditionally the approach to chronic cough in patients who are nonsmokers and are not taking an angiotensin-converting enzyme inhibitor has focused on the diagnosis and management of the upper airway cough syndrome, asthma, and reflux disease. The evaluation of patients with chronic cough frequently involves trials of empiric therapy for these 3 conditions. Chronic cough may be perpetuated by abnormalities of the cough reflex and sensitization of its afferent and central components.

    Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation which is not fully reversible. Despite the heterogeneity of COPD, its diagnosis and staging is currently based solely on forced expiratory volume in 1 s (FEV{sub 1}). FEV{sub 1} does not explain the underlying pathophysiology of airflow limitation. The relationship between FEV{sub 1}, symptoms and emphysema extent is weak. Better diagnostic tools are needed to define COPD. Tomographic lung scintigraphy [ventilation/perfusion single photon emission tomography (V/P SPECT)] visualizes regional V and P. In COPD, relations between V/P SPECT, spirometry, high-resolution computed tomography (HRCT) and symptoms have been insufficiently studied. The aim of this study was to investigate how lung function imaging and obstructive disease grading undertaken using V/P SPECT correlate with symptoms, spirometric lung function and degree of emphysema assessed with HRCT in patients with COPD. Thirty patients with stable COPD were evaluated with the Medical Research Council dyspnoea questionnaire (MRC) and the clinical COPD questionnaire (CCQ). Spirometry was performed. The extent of emphysema was assessed using HRCT. V/P SPECT was used to assess V/P patterns, total reduction in lung function and degree of obstructive disease. The total reduction in lung function and degree of obstructive disease, assessed with V/P SPECT, significantly correlated with emphysema extent (r = 0.66-0.69, p < 0.0001) and spirometric lung function (r = 0.62-0.74, p < 0.0005). The correlation between emphysema extent and spirometric lung function was weaker. No correlation between MRC, CCQ and objective measurements was found. V/P SPECT is sensitive to early changes in COPD. V/P SPECT also has the possibility to identify comorbid disease. V/P SPECT findings show a significant correlation with emphysema extent and spirometric lung function. We therefore recommend that scintigraphic signs of COPD, whenever found, should be

    Full Text Available Aims: The present study evaluated the utility of xenon computed tomography (Xe-CT as a noninvasive diagnostic procedure for the measurement of hepatic tissue blood flow (TBF in patients with nonalcoholic fatty liver disease (NAFLD or chronic hepatitis C (CH-C. Methods: Xe-CT was performed in 93 patients with NAFLD and in 109 patients with CH-C. Subjects were classified into one of three groups, based on fibrosis stage: group 1, no bridging fibrosis; group 2, bridging fibrosis; and group 3, liver cirrhosis. Correlations between hepatic TBFs in each fibrosis stage were examined. Results: In group 1, portal venous TBF (PVTBF, hepatic arterial (HATBF, and total hepatic TBF (THTBF were significantly lower in patients with in nonalcoholic steatohepatitis (NASH than in those with CH-C (p < 0.001, p < 0.05, p < 0.001, respectively. In group 2, PVTBF and THTBF were significantly lower in patients with in NASH than in those with CH-C (p < 0.001, p < 0.05, respectively. In group 3, hepatic TBFs were not significantly different when comparing patients with NASH and those with CH-C. Conclusions: PVTBF decreased due to fat infiltration. Therefore, hemodynamic changes occur relatively earlier in NAFLD than in CH-C. Patients with NASH should be monitored carefully for portal hypertensive complications in the early fibrosis stage.

    1997-01-01

    This study explores and describes experiences of chronic liver disease from the patient's perspective. No qualitative research studies appear to have examined the experiences of these patients. In-depth focused interviews and grounded theory data collection and data analysis methods were used. A two-stage theoretical framework (becoming ill, and not living) of the experience of transcending chronic liver disease is presented. Sociological and psychological literature on common sense models of health and illness are briefly reviewed. Several suggestions for further research are made. The way in which this qualitative research study is leading to a quantitative and qualitative appraisal of the psychological adjustment in end-stage chronic liver disease patients is outlined.

    Full Text Available Background. There continues to be uncertainty on the ideal treatment of pruritus in chronic liver disease. The aim of this study was to gather the latest information on the evidence-based management of pruritus in chronic liver disease. Methodology. A literature search for pruritus in chronic liver disease was conducted using Pubmed and Embase database systems using the MeSH terms “pruritus,” “chronic liver disease,” “cholestatic liver disease,” and “treatment.” Results. The current understanding of the pathophysiology of pruritus is described in addition to detailing research into contemporary treatment options of the condition. These medical treatments range from bile salts, rifampicin, and opioid receptor antagonists to antihistamines. Conclusion. The burden of pruritus in liver disease patients persists and, although it is a common symptom, it can be difficult to manage. In recent years there has been greater study into the etiology and treatment of the condition. Nonetheless, pruritus remains poorly understood and many patients continue to suffer, reiterating the need for further research to improve our understanding of the etiology and treatment for the condition.

Material and methods: In a review of 50 studies, 27 were selected since these met the inclusion criteria, like chronical disease, studies conducted between 2002 and 2011 related to costs, chronic disease, and being Colombian. Results: This is a review study of chronic diseases vs. their costs, being here cardiovascular diseases part of the group of high cost and higher incidence diseases, thus repre­senting a great risk to the financial stability of healthcare companies. There are few studies that address the costs generated by the treatment of ncds patients that show the economic impact experienced by public and private institutions providing and promoting health services. Most of them forget the economic, family and social costs the affected population must suffer. Conclu­sions: ncds represent a burden to the health service system for their very high costs, untimely intervention and reduced significant benefit for this population and their families.

    Full Text Available During the past decades there was an increasing predominance of chronic disorders, with a large number of people living with chronic diseases that can adversely affect their quality of life. The aim of the present paper is to study quality of life and especially Health-related quality of life (HRQoL in chronic diseases. HRQOL is a multidimensional construct that consists of at least three broad domains − physical, psychological, and social functioning − that are affected by one’s disease and/or treatment. HRQoL is usually measured in chronic conditions and is frequently impaired to a great extent. In addition, factors that are associated with good and poor HRQoL, as well as HRQoL assessment will be discussed. The estimation of the relative impact of chronic diseases on HRQoL is necessary in order to better plan and distribute health care resources aiming at a better HRQoL.[«All the people perceive the concept of living good or being well, that is the same as being happy».

    Cirrhotic patients are known to have abnormally high signal principally in the globus pallidus on non-contrast T1-weighted MRI. The purpose of this study was to relate MR changes to clinical and pathological features of chronic liver disease. We confirmed abnormally high signal in the globus pallidus on T1-weighted images in 25 of 28 patients with chronic liver disease, showing that it also occurs in patients who have not yet progressed to cirrhosis. Changes were seen in patients both with and without clinical portosystemic shunting. This abnormality is not responsible for hepatic encephalopathy. Cholestatic disease was more likely to produce marked changes than non-cholestatic disease. No statistically significant correlation was demonstrated between the severity of liver disease and the degree of MR abnormality. However, marked improvement in MR appearances was seen after successful liver transplantation. (orig.). With 3 figs., 4 tabs.

    Full Text Available Surgical or bronchoscopic lung volume reduction (BLVR techniques can be beneficial for heterogeneous emphysema. Post-processing software tools for lobar emphysema quantification are useful for patient and target lobe selection, treatment planning and post-interventional follow-up. We aimed to evaluate the inter-software variability of emphysema quantification using fully automated lobar segmentation prototypes.66 patients with moderate to severe COPD who underwent CT for planning of BLVR were included. Emphysema quantification was performed using 2 modified versions of in-house software (without and with prototype advanced lung vessel segmentation; programs 1 [YACTA v.2.3.0.2] and 2 [YACTA v.2.4.3.1], as well as 1 commercial program 3 [Pulmo3D VA30A_HF2] and 1 pre-commercial prototype 4 [CT COPD ISP ver7.0]. The following parameters were computed for each segmented anatomical lung lobe and the whole lung: lobar volume (LV, mean lobar density (MLD, 15th percentile of lobar density (15th, emphysema volume (EV and emphysema index (EI. Bland-Altman analysis (limits of agreement, LoA and linear random effects models were used for comparison between the software.Segmentation using programs 1, 3 and 4 was unsuccessful in 1 (1%, 7 (10% and 5 (7% patients, respectively. Program 2 could analyze all datasets. The 53 patients with successful segmentation by all 4 programs were included for further analysis. For LV, program 1 and 4 showed the largest mean difference of 72 ml and the widest LoA of [-356, 499 ml] (p<0.05. Program 3 and 4 showed the largest mean difference of 4% and the widest LoA of [-7, 14%] for EI (p<0.001.Only a single software program was able to successfully analyze all scheduled data-sets. Although mean bias of LV and EV were relatively low in lobar quantification, ranges of disagreement were substantial in both of them. For longitudinal emphysema monitoring, not only scanning protocol but also quantification software needs to be kept

    We report six cases of autoimmune thyroid disease associated with chronic urticaria and briefly review the literature, including the histopathological nature of such lesions, and their aetiology and pathogenesis. In view of the prevalence of thyroid disease in patients with chronic urticaria, screening measurements of thyrotropin and anti-thyroperoxidase antibodies are recommended, although negative antibodies do not exclude a relationship between urticaria and thyroid autoimmunity. After failure of conventional therapy for urticaria, patients who are apparently clinically euthyroid may be considered for a trial with levothyroxine. Improvement of urticaria was seen with levothyroxine treatment in three of four patients with only marginal abnormalities in thyroid function.

    Chronic parotitis is a troubling clinical condition characterized by repeated infection and inflammation of the parotid gland caused by decreased salivary flow or obstruction. Unilateral swelling, pain, and other associated symptoms occur during acute exacerbations of the disease. A variety of laboratory and radiographic tools are available to aid in the diagnosis. Multiple treatment options have been proposed, ranging from conservative medical management to surgical interventions. We present 2 patients with bilateral chronic parotitis who attempted prolonged medical management and ultimately required surgical parotidectomy for control of their disease.

    The serum concentrations of creatinine (Cre) and urea are used for the determination of the renal function. However, the use of blood is not always suitable due to the invasive, hygienic and infection problems during its sample collection and handling. In contrast, saliva is relatively clean and the samples can be quickly and noninvasively collected and easily stored. Therefore, the simultaneous determination of Arginine (Arg), creatine (Cr) and Cre in the saliva of chronic kidney disease (CKD) patients was performed by UPLC-ESI-MS/MS together with the saliva of healthy volunteers. The evaluation of hemodialysis of CKD patients was also carried out by the determinations before and after the dialysis. An HS-F5 column was used for the simultaneous determination of Arg, Cr and Cre in the saliva. These molecules were rapidly separated within 4 min and sensitively determined by the multiple reaction monitoring (MRM) of the precursor ion [M+H](+) → product ions (m/z 175.1 → 70.1 for Arg; m/z 132.0 → 44.1 for Cr; m/z 114.0 → 44.1 for Cre). The concentration of Cre in the CKD patients was higher than that in the healthy persons. The concentrations of Cre in the saliva of the patients before hemodialysis were moderately correlated with the serum Cre concentrations (R(2) = 0.661). Furthermore, the concentration in the saliva obviously decreased after hemodialysis (before 0.73 mg/dL, after 0.25 mg/dL; p saliva by UPLC-MS/MS is useful for the evaluation of the renal function in CKD patients. The present method offers a new option for monitoring the hemodialysis of CKD patients.

    Full Text Available Introduction. Nutritional abnormalities have one of the most important systematic effects on chronic obstructive pulmonary disease (COPD. A relationship between COPD and obesity has been observed and recognized. In COPD patients, beside changes in the total body weight, changes in body composition are also possible with the loss of fat-free mass (FFM. Objective. This study was undertaken to evaluate the impact of obesity and the change of body composition on the pulmonary function, dyspnoea level and the quality of life in COPD patients. Methods. Seventy-nine patients in the stable state of COPD were evaluated. Pulmonary function and arterial blood gas analysis were assessed. Nutritional status was analyzed according to Body Mass Index (BMI. Body composition was evaluated by using anthropometric measurement by fat free mass index (FFMI. Quality of life was assessed using the St. George Respiratory Questionnaire (SGRQ. The Visual Analogue Scale (VAS was used to evaluate dyspnoea. Results. The highest prevalence of obesity (50.0% was found in patients with mild COPD, while the lowest prevalence was detected in very severe COPD patients (10.0%. The loss of FFM occurred in 22.2% patients with normal body weight and in 9.0% of overweight COPD patients. The quality of life was lower in obese patients compared to other COPD patients. A higher dyspnoea level was also present in obese patients. The lowest airflow obstruction was in obese patients (p=0.023. We found a significant positive correlation between forced expiratory volume in the first second (FEV1% and BMI (r=0.326, p=0.003, FEV1% and FFMI (r=0.321, p=0.004. Conclusion. The highest prevalence of obesity was in patients with mild COPD. Obese patients with COPD had the lowest level of airflow obstruction, higher dyspnoea level and lower quality of life in comparison to other COPD patients.

  10. Social inequality in chronic disease outcomes.

    2014-11-01

    Socioeconomic differences in morbidity and mortality, particularly across educational groups, are widening. Differential exposures to behavioural risk factors have been shown to play an important mediating role on the social inequality in chronic diseases such as heart disease, cerebrovascular disease, chronic obstructive pulmonary disease, and lung cancer. However, much less attention has been given to the potential role of interaction, where the same level of exposure to a behavioural risk factor has different effect across socioeconomic groups, creating subgroups that are more vulnerable than others. In this thesis, Paper 1 describes the unique cohort consortium which was established by pooling and harmonising prospective data from existing cohort studies in Denmark. This consortium generated a large study population with long follow-up sufficient to study power demanding questions of mechanisms underlying social inequalities in chronic disease outcomes. In Paper 2 on incidence of coronary heart disease, smoking and body mass index partially mediated the observed educational differences. This result suggested that some of the social inequality in coronary heart disease may be enhanced by differential exposure to behavioural risk factors (i.e. smoking and obesity). In Paper 3 on incidence of stroke, an observed interaction between education and smoking indicated that participants, particularly men, with low level of education may be more vulnerable to the effect of smoking than those with high level of education in terms of ischemic stroke. Finally, Paper 4 revealed that behavioural risk factors, primarily smoking, explained a considerable part of the educational differences in cause-specific mortality. Further, this paper added important knowledge about the considerable part of the mediated effect, which could be due to interaction between education and smoking. In conclusion, the research in this thesis is a practical implementation of contemporary statistical

    Interleukin (IL)-10 is an important immunoregulatory cytokine produced by many cell populations. Numerous investigations suggest that IL-10 plays a major role in chronic liver diseases. IL-10 gene polymorphisms are possibly associated with liver disease susceptibility or severity. Recombinant human IL-10 has been produced and is currently tested in clinical trials. These trials may give new insights into the immunobiology of IL-10 and suggest that the IL-10/IL-10 receptor system may become a new therapeutic target.

    Full Text Available In this article, I present a phenomenological study of individuals’ experiences of living with moderate to very severe chronic lower pulmonary disease (chronic obstructive pulmonary disease, asthma, or both. Phenomenology is a philosophy, distinct from descriptive or thematic research, which is useful as a foundation for scientific inquiry. In this study, I used the lens of Merleau-Ponty to understand and interpret participants’ experiences of living with pulmonary disease, and the approach of van Manen for analysis. I conclude that in chronic pulmonary disease, awareness of breathing and the body is experienced in the sounds, sensations, and signals of breathing and the body, and in the experiences of the body-in-the-world. Central themes of being-in-the-world from the study describe the disruption of the embodied phenomenological self: Participants experienced slowing down, doing less, and having to stop due to shortness of breath. Both chronic and acute dyspnea were prevalent and the taken-for-granted aspects of daily activities were disrupted. Findings of this study have implications for public and patient education, and opportunities for integration of experiential aspects within nursing education and practice.

    Purpose The controversial diagnosis of chronic Lyme disease is often given to patients with prolonged, medically unexplained physical symptoms. Many such patients are also treated for chronic co-infections with Babesia, Anaplasma, or Bartonella in the absence of typical presentations, objective clinical findings, or laboratory confirmation of active infection. We have undertaken a systematic review of the literature to evaluate several aspects of this practice. Methods Five systematic literature searches were performed using Boolean operators and the PubMed search engine. Results The literature searches did not demonstrate convincing evidence of 1) chronic anaplasmosis infection, 2) treatment responsive symptomatic chronic babesiosis in immunocompetent persons in the absence of fever, laboratory abnormalities and detectable parasitemia, 3) either geographically widespread or treatment responsive symptomatic chronic infection with Babesia duncani in the absence of fever, laboratory abnormalities and detectable parasitemia, 4) tick-borne transmission of Bartonella species, or 5) simultaneous Lyme disease and Bartonella infection. Conclusions The medical literature does not support the diagnosis of chronic, atypical tick-borne coinfections in patients with chronic, nonspecific illnesses. PMID:24929022

  1. Endothelial Dysfunction in Chronic Inflammatory Diseases

    Full Text Available Chronic inflammatory diseases are associated with accelerated atherosclerosis and increased risk of cardiovascular diseases (CVD. As the pathogenesis of atherosclerosis is increasingly recognized as an inflammatory process, similarities between atherosclerosis and systemic inflammatory diseases such as rheumatoid arthritis, inflammatory bowel diseases, lupus, psoriasis, spondyloarthritis and others have become a topic of interest. Endothelial dysfunction represents a key step in the initiation and maintenance of atherosclerosis and may serve as a marker for future risk of cardiovascular events. Patients with chronic inflammatory diseases manifest endothelial dysfunction, often early in the course of the disease. Therefore, mechanisms linking systemic inflammatory diseases and atherosclerosis may be best understood at the level of the endothelium. Multiple factors, including circulating inflammatory cytokines, TNF-α (tumor necrosis factor-α, reactive oxygen species, oxidized LDL (low density lipoprotein, autoantibodies and traditional risk factors directly and indirectly activate endothelial cells, leading to impaired vascular relaxation, increased leukocyte adhesion, increased endothelial permeability and generation of a pro-thrombotic state. Pharmacologic agents directed against TNF-α-mediated inflammation may decrease the risk of endothelial dysfunction and cardiovascular disease in these patients. Understanding the precise mechanisms driving endothelial dysfunction in patients with systemic inflammatory diseases may help elucidate the pathogenesis of atherosclerosis in the general population.

    2013-07-01

    We evaluated population management programs for controlling chronic wasting disease (CWD) in wild white-tailed deer in Illinois between November 2002 and March 2008. The intervention consisted of measures of deer removal from three deer population control programs: Illinois Department of Natural Resources culling, deer population control permits and nuisance deer removal permits. We included in the analysis a total of 14,650 white-tailed deer CWD test results. These data also included location and demographic data collected from both deer harvested in the interventions as well as deer from hunter harvests and deer vehicle collisions. We quantified intervention pressures as the number of years of intervention, the total number of deer removed and the average number of deer removed per year. We accounted for temporal and spatial variations of intervention by using mixed logistic regression to model the association between intervention pressures and CWD prevalence change. The results showed that deer population management intervention as practiced in Illinois during the study period was negatively associated with CWD prevalence and the strength of association varied depending on age of deer and the measure of intervention pressure. The population management programs showed a more consistent association with reduced CWD prevalence in fawn and yearling white-tailed deer than in adult deer. Our results also suggested that frequent and continuing intervention events with at least moderate intensity of culling were needed to reduce CWD prevalence. A longer study period, however, is needed to make a more definite conclusion about the effectiveness of similar population management programs for controlling CWD in wild white-tailed deer.

    Full Text Available The New South Wales Health (NSW Health Chronic Disease Management Program (CDMP delivers interventions to adults at risk of hospitalisation for five target chronic conditions that respond well to ambulatory care: diabetes, hypertension, chronic obstructive pulmonary disease, congestive heart failure, and coronary artery disease. The intervention consists of two main components: (1 care coordination across sectors (acute, ambulatory, and community care from both public and private sectors and clinical specialties, facilitated by program care coordinators, and (2 health coaching including management of lifestyle risk factors and medications and self-management. These components were broadly prescribed by the head office of NSW Health, which funded the program, and were implemented by regional health services (local health districts in ways that best suited their own history, environment, workforce, and patient need. We used a propensity-matched cohort study to evaluate health service utilisation after enrolment in the CDMP.The evaluation cohort included 41,303 CDMP participants enrolled between 1 January 2011 and 31 December 2013 who experienced at least one hospital admission or emergency department (ED presentation for a target condition in the 12 mo preceding enrolment. Potential controls were selected from patients not enrolled in the CDMP but experiencing at least one hospital admission or ED presentation over the same period. Each CDMP patient in the evaluation cohort was matched to one control using 1:1 propensity score matching. The primary outcome was avoidable hospitalisations. Secondary outcomes included avoidable readmissions, avoidable bed days, unplanned hospitalisations, unplanned readmissions, unplanned bed days, ED presentations, and all-cause death. The primary analysis consisted of 30,057 CDMP participants and 30,057 matched controls with a median follow-up of 15 mo. Of those, 25,638 (85.3% and 25,597 (85.2% were alive by the

    Full Text Available Abstract Treatment of patients with chronic diseases will be one of the main challenges of medicine in the future. This paper presents an overview of different origins, mechanism, and symptoms necessary for understanding new and different interventions that include a psychosomatic view. In a psychosomatic therapeutic intervention there are very different targets, such as psychological symptoms, personality traits, attitudes toward disease and life, risk behaviour, and social isolation and as biological targets the change of autonomic imbalance and of the effects of the psycho-endocrinological or psycho-immunological stress responses. And there are also different psychosomatic measures that influence the individual biological, psychological and sociological targets. There is a need to give different answer to different questions in the field of psychosomatic and behavioral medicine. Comparative effectiveness research is an important strategy for solving some methodological issues. What is the target of treatment for different diseases: Symptom reduction, healing, or limiting progression to the worst case - the death of patients. We know that, the patient-physician relationship is important for every medical/therapeutic action for patients with chronic diseases. This volume of BioPsychoSocial Medicine will present four different psychosomatic treatment studies from the clinical field in the sense of phase 2 studies: Reports of patients with obesity, anorexia nervosa, chronic somatoform pain and coronary artery disease were presented

    Full Text Available Epidemiological and experimental studies have consistently linked alcoholic beverage consumption with the development of several chronic disorders, such as cancer, cardiovascular diseases, diabetes mellitus and obesity. The impact of drinking is usually dose-dependent, and light to moderate drinking tends to lower risks of certain diseases, while heavy drinking tends to increase the risks. Besides, other factors such as drinking frequency, genetic susceptibility, smoking, diet, and hormone status can modify the association. The amount of ethanol in alcoholic beverages is the determining factor in most cases, and beverage types could also make an influence. This review summarizes recent studies on alcoholic beverage consumption and several chronic diseases, trying to assess the effects of different drinking patterns, beverage types, interaction with other risk factors, and provide mechanistic explanations.

    Chronic obstructive pulmonary disease (COPD) is one of the most important respiratory diseases, characterized by its multicomponent complexity, with chronic inflammation, increased airway resistance and exacerbations. Several drugs are currently available for its treatment, which act on distinct targets. Bronchodilators, especially prolonged-action bronchodilators, are the most potent and there are two groups: beta-2 mimetics and anticholinergics. Inhaled corticosteroids are the main anti-inflammatory drugs but have modest efficacy and their use is reserved for patients with severe disease and frequent exacerbations and/or asthma traits. Associating these three drugs can improve symptom control, improve quality of life and reduce the number of exacerbations. The present article reviews the evidence supporting this triple combination, as well as published studies.

    2016-01-01

    Since antiquity, ginger or Zingiber officinale, has been used by humans for medicinal purposes and as spice condiments to enhance flavor in cooking. Ginger contains many phenolic compounds such as gingerol, shogaol and paradol that exhibit antioxidant, anti-tumor and anti-inflammatory properties. The role of ginger and its constituents in ameliorating diseases has been the focus of study in the past two decades by many researchers who provide strong scientific evidence of its health benefit. This review discusses research findings and works devoted to gingerols, the major pungent constituent of ginger, in modulating and targeting signaling pathways with subsequent changes that ameliorate, reverse or prevent chronic diseases in human studies and animal models. The physical, chemical and biological properties of gingerols are also described. The use of ginger and especially gingerols as medicinal food derivative appears to be safe in treating or preventing chronic diseases which will benefit the common population, clinicians, patients, researchers, students and industrialists.

    Male sexual dysfunction is common in chronic kidney disease (CKD), particularly in end-stage renal disease. Historically, this cause of considerable morbidity has been under-reported and under-recognized. The ideal approach to diagnosis and management remains unclear due to a paucity of good quality data, but an understanding of the pathophysiology is necessary in order to address the burden of this important complication of CKD. This paper will review the endocrine dysfunction that occurs in renal disease, particularly the hypothalamic–pituitary–gonadal axis, discuss the causes of erectile dysfunction, infertility, and altered body image and libido in these patients and suggest appropriate treatment interventions.

    Since liver function is changed by chronic liver diseases, chronic liver disease can lead to different hemorheological alterations during the course of the progression. This study aims to compare alterations in whole blood viscosity in patients with chronic liver disease, focusing on the gender effect. Chronic liver diseases were classified into three categories by patient's history, serologic markers, and radiologic findings: nonalcoholic fatty liver disease (NAFLD) (n = 63), chronic viral hepatitis B and C (n = 50), and liver cirrhosis (LC) (n = 35). Whole blood viscosity was measured by automated scanning capillary tube viscometer, while liver stiffness was measured by transient elastography using FibroScan®. Both systolic and diastolic whole blood viscosities were significantly lower in patients with LC than NAFLD and chronic viral hepatitis (P chronic viral hepatitis. Our data suggest that whole blood viscosity test can become a useful tool for classifying chronic liver disease and determining the prognosis for different types of chronic liver diseases.

    Full Text Available Cardiovascular is the major cause of death in chronic kidney disease and end-stage renal disease. The cardiovascular mortality rate of patients with renal impairment is evaluated to be higher than general population. Coronary artery disease seems to be an important type of cardiovascular complication among patients with chronic kidney disease and end-stage renal disease before the renal replacement therapy. Due to the strong association between chronic kidney disease and the incidence of coronary artery disease, accurate screening, diagnosis, and management of cardiovascular complications would be essential in patients at different stages of renal dysfunction. Despite the need for the comprehensive knowledge about different aspects of coronary artery disease in patients with renal failure, there is not sufficient evidence regarding the pathophysiology, ideal diagnosis, and treatment strategies for coronary heart disease in population with chronic kidney disease. In this study, we briefly reviewed the existing literatures about the possible screening, diagnosis, and the treatment approaches of risk of coronary heart disease in patients with kidney dysfunction.

    Katherine T Mills

    Full Text Available BACKGROUND: Adipokines have been associated with atherosclerotic heart disease, which shares many common risk factors with chronic kidney disease (CKD, but their relationship with CKD has not been well characterized. METHODS: We investigated the association of plasma leptin, resistin and adiponectin with CKD in 201 patients with CKD and 201 controls without. CKD was defined as estimated glomerular filtration rate (eGFR <60 mL/min/1.73 m(2 or presence of albuminuria. Quantile regression and logistic regression models were used to examine the association between adipokines and CKD adjusting for multiple confounding factors. RESULTS: Compared to controls, adjusted median leptin (38.2 vs. 17.2 ng/mL, p<0.0001 and adjusted mean resistin (16.2 vs 9.0 ng/mL, p<0.0001 were significantly higher in CKD cases. The multiple-adjusted odds ratio (95% confidence interval of CKD comparing the highest tertile to the lower two tertiles was 2.3 (1.1, 4.9 for leptin and 12.7 (6.5, 24.6 for resistin. Median adiponectin was not significantly different in cases and controls, but the odds ratio comparing the highest tertile to the lower two tertiles was significant (1.9; 95% CI, 1.1, 3.6. In addition, higher leptin, resistin, and adiponectin were independently associated with lower eGFR and higher urinary albumin levels. CONCLUSIONS: These findings suggest that adipocytokines are independently and significantly associated with the risk and severity of CKD. Longitudinal studies are warranted to evaluate the prospective relationship of adipocytokines to the development and progression of CKD.

The neuropsychological performance of 45 chronic Chagasic patients and 26 matched controls (age, education place and years of residency in endemic area was compared using the Mini Mental State Exam (MMSE, Weschler Memory Scale (WMS and the Weschler Adult Intelligent Scale (WAIS. Non-parametric tests and Chi2 were used to compare group means and multivariate statistics in two way frequency tables for measures of independence and association of categorical variables with the disease. Results: Chagasic patients showed lower MMSE scores (p<004, poor orientation (p<.004, and attention (p<.007. Lower WMS MQ were associated with CCD (Chi2 5.9; p<.01; Fisher test p<.02. Lower WAIS IQ were associated with CCD (Chi2 6.3, p<.01; Fisher test p<.01 being the digit symbol (p<.03, picture completion (p<.03, picture arrangement (p<.01 and object assembly (p<.03 subtests the most affected. The impairment in non-verbal reasoning, speed of information processing, problem solving, learning and sequencing observed in chronic Chagas disease patients resembles the cognitive dysfunction associated with white matter disease.

    Epaulard, Olivier; Foote, Alison; Bosson, Jean-Luc

    2015-09-01

    Venous thromboembolic disease often arises as a complication of another pathological condition and/or triggering event. Infectious diseases result from both the direct action of the pathogens themselves and their effect on the immune system. The resulting inflammatory process and the coagulation and fibrinolysis processes share common pathways, explaining why infection is associated with thrombosis. In this brief overview, besides certain chronic infectious diseases, we also consider some acute infections, as the mechanisms are likely to be similar, particularly in the initial infective stage or the more acute episodes of a chronic infection. The infectious agent can be viral, bacterial, fungal, or parasitic. However, the literature on the link between infections and venous thromboembolism (VTE) is uneven, favoring infections that are found in more developed countries where physicians have access to VTE diagnostic tools. Thus, large epidemiological studies in this field are restricted to a limited number of the common chronic infectious diseases such as tuberculosis, while for other infections, particularly parasitic and fungal infections, the link with VTE is only evoked in a few scattered case reports.

    The objective of this study was to observe trends in payer expenditures for plan members with one of 14 chronic, complex conditions comparing one group with a disease management program specific to their condition (the intervention group) and the other with no specific disease management program (the control group) for these conditions. The authors used payer claims and membership data to identify members eligible for the program in a 12-month baseline year (October 2001 to September 2002) and a subsequent 12-month program year (October 2002 to September 2003). Two payers were analyzed: one health plan with members primarily in New Jersey (AmeriHealth New Jersey [AHNJ]), where the disease management program was offered, and one affiliated large plan with members primarily in the metro Philadelphia area, where the program was not offered. The claims payment policy for both plans is identical. Intervention and control groups were analyzed for equivalence. The analysis was conducted in both groups over identical time periods. The intervention group showed statistically significant (p control group. Intervention group members showed a reduction in expenditures of -8%, while control group members showed an increase of +10% over identical time periods. Subsequent analyses controlling for outliers and product lines served to confirm the overall results. The disease management program is likely responsible for the observed difference between the intervention and control group results. A well-designed, targeted disease management program offered by a motivated, supportive health plan can play an important role in cost improvement strategies for members with complex, chronic conditions.

    Sleep disorders have a profound and well-documented impact on overall health and quality of life in the general population. In patients with chronic disease, sleep disorders are more prevalent, with an additional morbidity and mortality burden. The complex and dynamic relationship between sleep disorders and chronic kidney disease (CKD) remain relatively little investigated. This article presents an overview of sleep disorders in patients with CKD, with emphasis on relevant pathophysiologic underpinnings and clinical presentations. Evidence-based interventions will be discussed, in the context of individual sleep disorders, namely sleep apnea, insomnia, restless leg syndrome and excessive daytime sleepiness. Limitations of the current knowledge as well as future research directions will be highlighted, with a final discussion of different conceptual frameworks of the relationship between sleep disorders and CKD.

    that renin inhibition could hold potential for improved treatment in patients with chronic kidney disease, with diabetic nephropathy as an obvious group of patients to investigate, as the activity of the renin-angiotensin-aldosterone system is enhanced in these patients and as there is an unmet need....... In addition, combination treatment seemed safe and effective also in patients with impaired kidney function. These initial findings formed the basis for the design of a large morbidity and mortality trial investigating aliskiren as add-on to standard treatment. The study has just concluded, but was terminated...... early as a beneficial effect was unlikely and there was an increased frequency of side effects. Also in non-diabetic kidney disease a few intervention studies have been carried out, but there is no ongoing hard outcome study.

    A 78-year-old man with cryptogenic chronic bilateral lymphoplasmacytic pleuritis, diagnosed based on left parietal pleural biopsy specimens obtained by pleuroscopy, developed acute left bacterial pleuritis. The left pleural effusion was neutrophil dominant, however, the right pleural effusion showed lymphoplasmacytic infiltration. Laboratory examinations revealed that his serum IgG4 concentration was increased, with a higher level of IgG4 in the right pleural effusion. Re-evaluation of the previous biopsy specimens using an immunostaining method revealed numerous IgG4-positive plasma cell infiltrations with IgG4-positive/IgG-positive plasma cells at 85.4%. Accordingly, the new diagnosis of this patient was considered to be chronic bilateral IgG4-related pleuritis.

    Creutzberg, E C; Casaburi, R

    2003-11-01

    In this overview, the available literature on endocrinological disturbances in chronic obstructive pulmonary disease (COPD) is reviewed, with stress on growth hormone/insulin-like growth factor I (IGF-I), thyroid hormone and the anabolic steroids. In COPD, little is known about circulating growth hormone or IGF-I concentrations. Some authors find a decrease in growth hormone or IGF-I, others an increase. An increase of growth hormone might reflect a nonspecific response of the body to stress (for instance, hypoxaemia). Until now, only one controlled study on growth hormone supplementation has been published, which however did not reveal any functional benefits. Before growth hormone supplementation can be advised as part of the treatment in COPD, further controlled studies must be performed to investigate its functional efficacy. The prevalence of thyroid dysfunction in COPD and its role in pulmonary cachexia has not been extensively studied. So far, there is no evidence that thyroid function is consistently altered in COPD, except perhaps in a subgroup of patients with severe hypoxaemia. Further research is required to more extensively study the underlying mechanisms and consequences of disturbed thyroid function in this subgroup of COPD patients. A few studies have reported the results of anabolic steroid supplementation in chronic obstructive pulmonary disease. Although some studies have discerned that low circulating levels of testosterone are common in males with chronic obstructive pulmonary disease, little is known about the prevalence, the underlying causes or functional consequences of hypogonadism in these patients. The use of systemic glucocorticosteroids and an influence of the systemic inflammatory response have been suggested as contributing to low testosterone levels. It can be hypothesised that low anabolic hormones will reduce muscle mass and eventually result in a diminished muscle function. Further evidence is required before testosterone

Each cancer patient (n=3835, mean age 72 was matched with four non-cancer patients in terms of age, sex, and practice. The occurrence of chronic diseases was assessed cross-sectionally (lifetime prevalence at time of diagnosis and longitudinally (incidence after diagnosis for all cancer patients and for breast, prostate, and colorectal cancer patients separately. Cancer and non-cancer patients were compared using logistic and Cox regression analysis. Results. The occurrence of the most common pre-existing and incident chronic diseases was largely similar in cancer and non-cancer patients, except for pre-existing COPD (OR 1.21, 95% CI 1.06–1.37 and subsequent venous thrombosis in the first two years after cancer diagnosis (HR 4.20, 95% CI 2.74–6.44, which were significantly more frequent (P<0.01 among older cancer compared to non-cancer patients. Conclusion. The frequency of multimorbidity in older cancer patients is high. However, apart from COPD and venous thrombosis, the incidence of chronic diseases in older cancer patients is similar compared to non-cancer patients of the same age, sex, and practice.

    Coronary artery disease, hypertension, congestive heart failure, type 2 diabetes mellitus, osteoarthritis, osteoporosis, and cognitive disorders become more prevalent as people age. Besides delaying the onset of many of these conditions, regular exercise may improve function and delay disability and morbidity in those who have them. Further, exercise may work synergistically with medication to combat the effects of some chronic diseases. Special adaptations for older patients include lower-intensity exercise (eg, fewer repetitions), low-impact exercise (cycling, exercise while sitting), and modified equipment (smaller weights, special shoes, loose clothing). Unresolved issues include development of optimal strategies for motivating older patients to begin and maintain exercise programs.

    A structured literature review was performed to detail the frequency and etiology of chronic liver disease (CLD) in Aboriginal North Americans. CLD affects Aboriginal North Americans disproportionately and is now one of the most common causes of death.Alcoholic liver disease is the leading etiology of CLD,but viral hepatitis, particularly hepatitis C, is an important and growing cause of CLD. High rates of autoimmune hepatitis and primary biliary cirrhosis (PBC) are reported in regions of coastal British Columbia and southeastern Alaska. Non-alcoholic liver disease is a common, but understudied, cause of CLD.Future research should monitor the incidence and etiology of CLD and should be geographically inclusive.In addition, more research is needed on the treatment of hepatitis C virus (HCV) infection and non-alcoholicfatty liver disease (NAFLD) in this population.

    Pain in sickle cell disease (SCD) is associated with increased morbidity, mortality, and high health care costs. Although episodic acute pain is the hallmark of this disorder, there is an increasing awareness that chronic pain is part of the pain experience of many older adolescents and adults. A common set of criteria for classifying chronic pain associated with SCD would enhance SCD pain research efforts in epidemiology, pain mechanisms, and clinical trials of pain management interventions, and ultimately improve clinical assessment and management. As part of the collaborative effort between the Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks public-private partnership with the U.S. Food and Drug Administration and the American Pain Society, the Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks-American Pain Society Pain Taxonomy initiative developed the outline of an optimal diagnostic system for chronic pain conditions. Subsequently, a working group of experts in SCD pain was convened to generate core diagnostic criteria for chronic pain associated with SCD. The working group synthesized available literature to provide evidence for the dimensions of this disease-specific pain taxonomy. A single pain condition labeled chronic SCD pain was derived with 3 modifiers reflecting different clinical features. Future systematic research is needed to evaluate the feasibility, validity, and reliability of these criteria.

    Although chronic obstructive pulmonary disease (COPD) is characterized by poorly reversible, chronic airflow obstruction, from the clinical point of view we must continue to make progress in the diagnosis and management of these patients so that spirometry is not the only technique used. Understanding that COPD is a heterogeneous process and that patient complexity usually increases due to the presence of comorbidities will allow more individualized strategies to be designed, which may improve control of the process. The TORCH and UPLIFT trials have shown that current treatment can improve important aspects of the disease, including mortality. However, the finalizing of these two large trials has generated a current of opinion favoring a more individually-tailored approach that should include all the factors -both pulmonary and extrapulmonary- that can modify the patient's form of presentation. Although we are witnessing a change in the therapeutic approach to COPD, future treatment will probably be based on studies performed in specific patient subgroups and on clarifying the interrelation between COPD and other diseases that are common in these patients. Greater knowledge of the pathogenesis of the disease may improve pharmacological treatment but drugs that, by themselves, alter the short- and longterm course of COPD are not on the horizon. However, a more patient-focussed approach may be the main tool available to physicians to increase quality of life -and possibly survival- in these patients.

    Vitamin D is an important secosteroid hormone with known effect on calcium homeostasis,but recently there is increasing recognition that vitamin D also is involved in cell proliferation and differentiation,has immunomodulatory and anti-inflammatory properties.Vitamin D deficiency has been frequently reported in many causes of chronic liver disease and has been associated with the development and evolution of non-alcoholic fatty liver disease(NAFLD)and chronic hepatitis C(CHC)virus infection.The role of vitamin D in the pathogenesis of NAFLD and CHC is not completely known,but it seems that the involvement of vitamin D in the activation and regulation of both innate and adaptive immune systems and its antiproliferative effect may explain its importance in these liver diseases.Published studies provide evidence for routine screening for hypovitaminosis D in patients with liver disease.Further prospectives studies demonstrating the impact of vitamin D replacement in NAFLD and CHC are required.

  17. Role of cannabinoids in chronic liver diseases

    2008-01-01

    Cannabinoids are a group of compounds acting primarily via CB1 and CB2 receptors. The expression of cannabinoid receptors in normal liver is low or absent. However, many reports have proven up-regulation of the expression of CB1 and CB2 receptors in hepatic myofibroblasts and vascular endothelial cells, as well as increased concentration of endocannabinoids in liver in the course of chronic progressive liver diseases. It has been shown that CB1 receptor signalling exerts profibrogenic and proinflammatory effects in liver tissue, primarily due to the stimulation of hepatic stellate cells, whereas the activation of CB2 receptors inhibits or even reverses liver fibrogenesis. Similarly, CB1 receptor stimulation contributes to progression of liver steatosis. In end-stage liver disease, the endocannabi-noid system has been shown to contribute to hepatic encephalopathy and vascular effects, such as portal hypertension, splanchnic vasodilatation, relative pe-ripheral hypotension and probably cirrhotic cardiomy-opathy. So far, available evidence is based on cellular cultures or animal models. Clinical data on the effects of cannabinoids in chronic liver diseases are limited. However, recent studies have shown the contribution of cannabis smoking to the progression of liver fibrosis and steatosis. Moreover, controlling CB1 or CB2 signal-ling appears to be an attractive target in managing liver diseases.

    Chronic kidney disease (CKD) is highly prevalent and has major health consequences for patients. Caring for patients with CKD requires knowledge of the food supply, renal pathophysiology, and nutrition-related medications used to work synergistically with diet to control the signs and symptoms of the disease. The nutrition care process and International Dietetic and Nutrition Terminology allow for systematic, holistic, quality care of patients with this complex, progressive disease. Nutrition interventions must be designed with the individual patients needs in mind while prioritizing factors with the largest negative impact on health outcomes and mortality risk. New areas of nutrition treatment are emerging that involve a greater focus on micronutrient needs, the microbiome, and vegetarian-style diets. These interventions may improve outcomes by decreasing inflammation, improving energy and protein delivery, and lowering phosphorus, electrolytes, and fluid retention.

    Chronic kidney disease and diabetes mellitus represent a worldwide public health problem. The incidence of these diseases is gradually growing into epidemic proportions. In many cases they occur simultaneously, what leads to increased morbidity and mortality among the affected patients. The majority of the patients treated for diabetes mellitus are unaware of the presence of renal insufficiency. Vascular hypertrophy and diabetic kidney disease in patients with type 2 diabetes are the most common causes of kidney failure in countries with advanced healthcare systems. Metformin is a basic drug used for the treatment of type 2 diabetes mellitus. It is excreted in an unchanged form by the kidneys. When administered to patients with renal insufficiency, sepsis, dehydration or after the parenteral administration of iodinated contrast agents, metformin can cause lactic acidosis, which is also associated with an increased mortality rate.

    Chronic kidney disease-related mineral and bone disease (CKD-MBD) is a syndrome defined as a systemic mineral metabolic disorder associated with CKD, and the term renal osteodystrophy indicates a pathomorphological concept of bone lesions associated with CKD-MBD. Cortical bone thinning, abnormalities in bone turnover and primary/secondary mineralization, elevated levels of circulating sclerostin, increased apoptosis in osteoblasts and osteocytes, disturbance of the coupling phenomenon, iatrogenic factors, accumulated micro-crackles, crystal/collagen disorientation, and chemical modification of collagen crosslinks are all possible candidates found in CKD that could promote osteopenia and/or bone fragility. Some of above factors are the consequences of abnormal systemic mineral metabolism but for others it seem unlikely. We have used the term uremic osteoporosis to describe the uremia-induced bone fragility which is not derived from abnormal systemic mineral metabolism. Interestingly, the disease aspect of uremic osteoporosis appears to be similar to that of senile osteoporosis.

    Chronic granulomatous disease (CGD) is a primary immunodeficiency caused by a defect in production of phagocyte-derived reactive oxygen species, which leads to recurrent infections with a characteristic group of pathogens not previously known to include methylotrophs. Methylotrophs are versatile environmental bacteria that can use single-carbon organic compounds as their sole source of energy; they rarely cause disease in immunocompetent persons. We have identified 12 infections with methylotrophs (5 reported here, 7 previously reported) in patients with CGD. Methylotrophs identified were Granulibacter bethesdensis (9 cases), Acidomonas methanolica (2 cases), and Methylobacterium lusitanum (1 case). Two patients in Europe died; the other 10, from North and Central America, recovered after prolonged courses of antimicrobial drug therapy and, for some, surgery. Methylotrophs are emerging as disease-causing organisms in patients with CGD. For all patients, sequencing of the 16S rRNA gene was required for correct diagnosis. Geographic origin of the methylotroph strain may affect clinical management and prognosis.

    Full Text Available Background : Chronic obstructive pulmonary diseases (COPD, a broad spectrum of respiratory diseases represents a worldwide problem. Electrocardiographic (ECG findings may help in clinical decision making regarding this disease entity. Aims: To evaluate the extent and diagnostic values of ECG changes among COPD patients suffering from broad spectrum of respiratory diseases. Material & Methods : A hos-pital based cross-sectional study was conducted in Sworoop Rani Nehru Hospital, Allahabad in Eastern Uttar Pradesh (UP, India. A sample of 60 patients attending respiratory diseases OPD for treatment of various respiratory problems including 14 COPD patients was selected randomly during 2000-2001. Patients of respiratory diseases were also evaluated electrocardiographically along with other investiga-tions. Results : Respiratory problems were more common among rural males of low socio-economic group. COPD particularly chronic bronchitis was the commonest respiratory problem next to pulmonary tuberculosis. Inspite of normal heart rate observed in 71.4% COPD patients, ECG changes were present in 35.7% COPD patients. Peaked P-wave was observed in 35.7% COPD patients, whereas duration of QRS complex was abnormal in only 8.1% of the patients. None of the COPD patients showed abnormal P-wave duration. ECG changes were found less sensitive (35.7% but highly specific (95.6%. Conclusion : Diagnostic values of ECG among patients with respiratory problems suggest that COPD patients should be screened electrocardiographically in addition to other clinical investigations.

    Medical treatment for patients with stable chronic obstructive pulmonary disease (COPD) has evolved significantly over the past 2 decades. Current World Health Organization recommendations suggest a stepwise approach to therapy depending upon disease severity. As-needed use of short-acting bronchodilators is recommended for patients with mild disease. Scheduled dosing of bronchodilators is recommended for patients with more advanced disease. Inhaled beta-agonists and anti-cholinergic agents in combination have proved to be more effective than either agent alone. Long-acting preparations are associated with better disease control and have not been associated with tachyphylaxis. Inhaled corticosteroids are useful for reducing the frequency of exacerbations in patients who experience one or more episodes per year. Oxygen therapy is clearly beneficial in patients with advanced COPD and chronic respiratory failure, and its potential benefits in less severe disease are currently being studied. Pulmonary rehabilitation benefits patients with mild-to-severe disease, although the greatest benefits have been demonstrated in those with moderate COPD. New ultra-long-acting inhaled bronchodilators, phosphodiesterase inhibitors, protease inhibitors, and retinoids intended to promote tissue regeneration are currently being evaluated in clinical trials as future therapeutic agents.

    The growing epidemic of obesity and diabetes, the aging population as well as prevalence of drug abuse has led to significant increases in the rates of the closely associated acute and chronic kidney diseases, including diabetic nephropathy. Furthermore, evidence shows that parental behavior and diet can affect the phenotype of subsequent generations via epigenetic transmission mechanisms. These data suggest a strong influence of the environment on disease susceptibility and that, apart from genetic susceptibility, epigenetic mechanisms need to be evaluated to gain critical new information about kidney diseases. Epigenetics is the study of processes that control gene expression and phenotype without alterations in the underlying DNA sequence. Epigenetic modifications, including cytosine DNA methylation and covalent post-translational modifications of histones in chromatin, are part of the epigenome, the interface between the stable genome and the variable environment. This dynamic epigenetic layer responds to external environmental cues to influence the expression of genes associated with disease states. The field of epigenetics has seen remarkable growth in the past few years with significant advances in basic biology, contributions to human disease, as well as epigenomics technologies. Further understanding of how the renal cell epigenome is altered by metabolic and other stimuli can yield novel new insights into the pathogenesis of kidney diseases. In this review, we have discussed the current knowledge on the role of epigenetic mechanisms (primarily DNAme and histone modifications) in acute and chronic kidney diseases, and their translational potential to identify much needed new therapies.

    Chronic non-communicable diseases (NCDs) are the leading causes of morbidity and mortality in the United States and globally, and are attributable largely to poor nutrition and suboptimal lifestyle behaviors. The 2015-2020 Dietary Guidelines for Americans promote healthy eating and lifestyle patterns across the lifespan to reduce risk of NCDs. Physicians are well positioned to provide lifestyle preventive interventions that are personalized to their patients' biological needs and cultural preferences through multidisciplinary team activities or referral to professional nutrition and physical activity experts. They can also advocate for environmental changes in healthcare and community settings that promote healthful lifestyle behaviors.

    Full Text Available Furosemide test is a simple and useful test of renal physiology used to evaluate the capability of the collecting tubules to secrete potassium under the effect of serum aldosterone. Its behaviour pattern has already been established in children and young adults but not described in chronic renal disease patients yet, which we explored in this study.Material & Method: Twenty-six young volunteers (between 20 and 40 years old, chronically on a low potassium diet (40 mmol of K day were studied: twenty of them were healthy young ( they were neither suffering form diseases nor on any medication, and the rest were young patients suffering from stage II / III chronic renal disease (damaged kidney with GFR between 83.1 ml-min to 39.2 ml-min secondary to glomerular diseases documented by kidney biopsy. None of the studied chronic renal disease patients were suffering from diabetes mellitus, urinary obstruction, nor treated with dyskalemia generating drugs, such as: diuretics, angiotensin converting enzyme inhibitors, angiotensin receptor antagonists, etc. Before, while the test was being carried out and after 180 minutes of a single dose of intravenous furosemide (1 mg/kg, urine and blood samples were obtained, for creatinine and potassium levels. From these data we calculated fractional excretion (FE of potassium.

    Full Text Available Chronic obstructive pulmonary disease (COPD is characterized by the progression of irreversible airflow limitation and is a leading cause of morbidity and mortality worldwide. Although several crucial mechanisms of COPD pathogenesis have been studied, the precise mechanism remains unknown. Extracellular vesicles (EVs, including exosomes, microvesicles, and apoptotic bodies, are released from almost all cell types and are recognized as novel cell–cell communication tools. They have been shown to carry and transfer a wide variety of molecules, such as microRNAs, messenger RNAs, and proteins, which are involved in physiological functions and the pathology of various diseases. Recently, EVs have attracted considerable attention in pulmonary research. In this review, we summarize the recent findings of EV-mediated COPD pathogenesis. We also discuss the potential clinical usefulness of EVs as biomarkers and therapeutic agents for the treatment of COPD.

    Full Text Available Oxidative stress is a common feature observed in a wide spectrum of chronic liver diseases including viral hepatitis, alcoholic, and nonalcoholic steatohepatitis. The nicotinamide adenine dinucleotide phosphate (NADPH oxidases (NOXs are emerging as major sources of reactive oxygen species (ROS. Several major isoforms are expressed in the liver, including NOX1, NOX2, and NOX4. While the phagocytic NOX2 has been known to play an important role in Kupffer cell and neutrophil phagocytic activity and inflammation, the nonphagocytic NOX homologues are increasingly recognized as key enzymes in oxidative injury and wound healing. In this review, we will summarize the current advances in knowledge on the regulatory pathways of NOX activation, their cellular distribution, and their role in the modulation of redox signaling in liver diseases.

    Chronic lymphocytic leukemia (CLL) is the most common lymphoproliferative disorder in the western hemisphere, with an annual incidence of 3:100000. Commonly patients are asymptomatic but not rarely disease progression occurs in the setting of lymphadenopathy and extensive leukemic burden. Leptomeningeal involvement in patients with CLL is infrequent, with presenting symptoms of headache (23%), acute or chronic changes in mental status (28%), cranial nerve abnormalities (54%) including optic neuropathy (28%), weakness of lower extremities (23%) and cerebellar signs (18%). In this report, we discuss a CLL patient with leptomeningeal involvement, who presented with neurological symptoms as the first clinical sign, and a diagnosis of leptomeningeal was made based on CSF cytology and flow cytometry. Treatment consisted of radiation therapy and intrathecal chemotherapy with arabinoside-cytosine and systemic chemotherapy. On the basis of this patient-report together with 37 other previously reported cases, the clinical characteristics together with treatment options and outcome of leptomeningeal involvement in CLL are reviewed. Our case together with data from the literature indicate that a timely diagnosis and intensive treatment of leptomeningeal disease of CLL may lead to longstanding and complete resolution of neurological symptoms.

    Two hundred seventy-seven patients with chronic Lyme disease were treated with tetracycline for 1 to 11 months (mean, 4 months); the outcomes for these patients were generally good. Overall, 20% of the patients were cured; 70% of the patients' conditions improved, and treatment failed for 10% of the patients. Improvement frequently did not take place for several weeks; after 2 months of treatment, 33% of the patients' conditions were significantly improved (degree of improvement, 75%-100%), and after 3 months of treatment, 61% of the patients' conditions were significantly improved. Treatment outcomes for seronegative patients (20% of all patients) were similar to those for seropositive patients. Western immunoblotting showed reactions to one or more Borrelia burgdorferi-specific proteins for 65% of the patients for whom enzyme-linked immunosorbent assays were negative. Whereas age, sex, and prior erythema migrans were not correlated with better or worse treatment outcomes, a history of longer duration of symptoms or antibiotic treatment was associated with longer treatment times to achieve improvement and cure. These results support the use of longer courses of treatment in the management of patients with chronic Lyme disease. Controlled trials need to be conducted to validate these observations.

    Full Text Available Abstract Chronic obstructive pulmonary disease (COPD is a major global health problem and is predicted to become the third most common cause of death by 2020. Apart from the important preventive steps of smoking cessation, there are no other specific treatments for COPD that are as effective in reversing the condition, and therefore there is a need to understand the pathophysiological mechanisms that could lead to new therapeutic strategies. The development of experimental models will help to dissect these mechanisms at the cellular and molecular level. COPD is a disease characterized by progressive airflow obstruction of the peripheral airways, associated with lung inflammation, emphysema and mucus hypersecretion. Different approaches to mimic COPD have been developed but are limited in comparison to models of allergic asthma. COPD models usually do not mimic the major features of human COPD and are commonly based on the induction of COPD-like lesions in the lungs and airways using noxious inhalants such as tobacco smoke, nitrogen dioxide, or sulfur dioxide. Depending on the duration and intensity of exposure, these noxious stimuli induce signs of chronic inflammation and airway remodelling. Emphysema can be achieved by combining such exposure with instillation of tissue-degrading enzymes. Other approaches are based on genetically-targeted mice which develop COPD-like lesions with emphysema, and such mice provide deep insights into pathophysiological mechanisms. Future approaches should aim to mimic irreversible airflow obstruction, associated with cough and sputum production, with the possibility of inducing exacerbations.

    Full Text Available Chronic kidney disease, despite being a “silent epidemic” disease, represents one of the main causes of mortality in general population, along with cardiovascular disease, which is the leading cause of poor prognosis for these patients. The specific objective of our study was to characterize the relationship between the inflammatory status, the bone disorders markers, and kidney failure in chronic kidney disease patient stages 2–4, in order to design a novel biomarker panel that improves early disease diagnosis and therapeutic response, thus being further integrated into clinical applications. A panel of proteomic biomarkers, assessed by xMAP array, which includes mediators of inflammation (IL-6, TNF-α and mineral and bone disorder biomarkers (OPG, OPN, OCN, FGF-23, and Fetuin-A, was found to be more relevant than a single biomarker to detect early CKD stages. The association between inflammatory cytokines and bone disorders markers, IL-6, TNF-α, OPN, OPG, and FGF-23, reflects the severity of vascular changes in CKD and predicts disease progression. Proteomic xMAP analyses shed light on a new approach to clinical evaluation for CKD staging and prognosis.

    Full Text Available Background: Chronic Kidney Disease (CKD is one of the most severe diseases worldwide. In patients affected by CKD, a progressive destruction of the nephrons is observed not only in structuralbut also in functional level. Atherosclerosis is a progressive disease of large and medium-sized arteries. It is characterized by the deposition of lipids and fibrous elements and is a common complication of the uremic syndrome because of the coexistence of a wide range of risk factors. High blood pressure, anaemia, insulin resistance, inflammation, high oxidative stress are some of the most common factors that cause cardiovascular disease and atherogenesis in patients suffering from End Stage Kidney Disease (ESRD. At the same time, the inflammatory process constitutes a common element in the apparition and development of CKD. A wide range of possible causes can justify the development of inflammation under uremic conditions. Such causes are oxidative stress, oxidation, coexistentpathological conditions as well as factors that are due to renal clearance techniques. Patients in ESRD and coronary disease usually show increased acute phase products. Pre-inflammatory cytokines, such as IL-6 and TNF-a, and acute phase reactants, such as CRP and fibrinogen, are closely related. The treatment of chronic inflammation in CKD is of high importance for the development ofthe disease as well as for the treatment of cardiovascular morbidity.Conclusions: The treatment factors focus on the use of renin-angiotensic system inhibitors, acetylsalicylic acid, statins and anti-oxidant treatment in order to prevent the action of inflammatorycytokines that have the ability to activate the mechanisms of inflammation.

Obesity raises blood pressure by increasing renal tubular sodium reabsorption, impairing pressure natriuresis, and causing volume expansion via activation of the sympathetic nervous system and renin-angiotensin-aldosterone system and by physical compression of the kidneys, especially when there is increased visceral adiposity. Other factors such as inflammation, oxidative stress, and lipotoxicity may also contribute to obesity-mediated hypertension and renal dysfunction. Initially, obesity causes renal vasodilation and glomerular hyperfiltration, which act as compensatory mechanisms to maintain sodium balance despite increased tubular reabsorption. However, these compensations, along with increased arterial pressure and metabolic abnormalities, may ultimately lead to glomerular injury and initiate a slowly developing vicious cycle that exacerbates hypertension and worsens renal injury. Body weight reduction, via caloric restriction and increased physical activity, is an important first step for management of obesity, hypertension, and chronic kidney disease. However, this strategy may not be effective in producing long-term weight loss or in preventing cardiorenal and metabolic consequences in many obese patients. The majority of obese patients require medical therapy for obesity-associated hypertension, metabolic disorders, and renal disease, and morbidly obese patients may require surgical interventions to produce sustained weight loss.

    Chronic obstructive pulmonary disease (COPD) is defined by fixed airflow limitation associated with an abnormal pulmonary and systemic inflammatory response of the lungs to cigarette smoke. COPD represents an increasing burden worldwide, reported to be the sixth leading cause of death in 1990 and the fourth in 2000. Discouragingly, it is projected to jump to third place by the year 2020.There is increasing evidence that COPD is a more complex systemic disease than an airway and lung disease. In particular, cachexia, skeletal muscle abnormalities, diabetes, coronary artery disease, heart failure, cancer and pulmonary vascular disease are the most common comorbidities. It is associated with a wide variety of systemic consequences, most notably systemic inflammation. Because COPD patients have in general ahigher cardiovascular risk than the average population, cardiovascular safety in a COPD medication is of critical importance.SINGH et al performed a systematic review and recta-analysis of 17 clinical trials enrolling 14 783 patients treated with inhaled anticholinergic drugs used for the treatment of COPD. Inhaled anticholinergics significantly increased the risk of cardiovascular death, MI, or stroke ( 1.8 % vs 1.2 % for control; RR, 1.58 (95 % CI,1.21 - 2.06); P < 0.001 ). However, UPLIIFT (Understanding the Potential Long-Term Impacts on Function with Tiotropium) , a large, 4-year, placebo controlled clinical trial with tiotropium in approximately 6 000 patients with COPD. The preliminary results of UPLIFT showed that there was no increased risk of stroke with tiotropium bromide compared to placebo.A meta-analysis is always considered less convincing than a large prospective trial designed to assess the outcome of interest. However, COPD is a systemic disease. COPD management needs to focus on four major areas: smoking cessation, pharmacologic therapy, exercise training, and pulmonary rehabilitation. Clinicians and patients should always carefully consider any

    Anemia of chronic disease is normocytic and normochromic. One of the mechanisms is misbalance of iron metabolism. Hepcidin, a kind of protein secreted by liver is considered to be the hormone regulating iron metabolism. It binds to ferroportin and induces the latter one's internalization. Thus, iron transportation from iron storage cells to serum is reduced. Cytokines are elevated in chronic disease. They stimulate hepcidin expression in liver through JAK2/STAT3 pathway. As a result, iron absorption and reabsorption is blocked, which leads to the misbalance of iron metabolism in anemia of chronic disease. In this article, the hepcidin and its relation to iron metabolism and anemia in chronic disease are reviewed.

    Full Text Available Introduction: Decreased oral intake or impaired function / structure in the gut, such as hypertension port associated with atrophic changes in the protein nutrition - calories can lead to micronutrient deficiencies.This paper examines the status of micronutrients in chronic liver disease in children.   Materials and Methods: In this review study databases including proquest, pubmedcentral, scincedirect, ovid, medlineplus were been searched with keyword words such as” chronic liver disease"” minerals””children” between 1999 to 2014. Finally, 3 related articles have been found.   Results: In chronic liver disease changes in micronutrient metabolism lead to changes in the daily requirements, such that in certain circumstances intake increasing or decreasing  is needed. Low serum calcium and phosphate concentrations are often the reflection of malabsorption-induced bone disease that is unresponsive to vitamin D store normalization. Iron is usually deficient in children with CLD and supplementation frequently needed. The origin of iron deficiency is multifactorial and includes ongoing losses, inadequate intakes, serial blood draws and malabsorption secondary to hypertensive enteropathy. Zinc plays an important role in cognitive function, appetite and taste, immune function, wound healing, and protein metabolism. Low plasma zinc levels are frequent in children with chronic cholestasis, but unfortunately plasma concentrations are not reflective of total body zinc status. Copper and manganese, unlike other minerals, are increased in CLD, because they are normally excreted through bile. Parenteral nutrition in cholestatic patients can induce manganese intoxication and accumulation in basal ganglia.   Conclusion:  In fants with CLD are prone to multiple nutritional deficiencies. Mineral state should be evaluated, treated and reevaluated, until sufficient daily requirement achieved. Poster  Presentation, N 33

    Renal resistive index (RRI) measured by Doppler ultrasonography is associated with cardiovascular events and mortality in hypertensive, diabetic, and elderly patients. We studied the factors associated with high RRI (≥0.70) and its associations with mortality in chronic kidney disease patients without renal artery stenosis. We included 1962 patients with an estimated glomerular filtration rate of 15 to 59 mL/min per 1.73 m(2) who also had RRI measured (January 1, 2005, to October 2011) from an existing chronic kidney disease registry. Participants with renal artery stenosis (60%-99% or renal artery occlusion) were excluded. Multivariable logistic regression model was used to study factors associated with high RRI (≥0.70), and its association with mortality was studied using Kaplan-Meier plots and Cox proportional hazards model. Hypertension was prevalent in >90% of the patients. In the multivariable logistic regression, older age, female sex, diabetes mellitus, coronary artery disease, peripheral vascular disease, higher systolic blood pressure, and the use of β blockers were associated with higher odds of having RRI≥0.70. During a median follow-up of 2.2 years, 428 patients died. After adjusting for covariates, RRI≥0.70 was associated with increased mortality (adjusted hazard ratio, 1.29; 95% confidence interval, 1.02-1.65; Pchronic kidney disease. Noncardiovascular/non-malignancy-related deaths were higher in those with RRI≥0.70. RRI≥0.70 is associated with higher mortality in hypertensive chronic kidney disease patients without clinically significant renal artery stenosis after accounting for other significant risk factors. Its evaluation may allow early identification of those who are at risk thereby potentially preventing or delaying adverse outcomes.

    Iodinated contrast (IC) is clinically used in diagnostic and interventional procedures, but its use can result in contrast-induced acute kidney injury (CI-AKI). Chronic kidney disease (CKD) and chronic hyperglycemia (CH) are important predisposing factors to CI-AKI. The aim of this study was to investigate the impact of iodinated contrast on the renal function and hemodynamics in rats with chronic hyperglycemia and chronic kidney disease. A total of 30 rats were divided into six groups; Sham: control of chronic renal disease; Citrate: control of chronic hyperglycemia (CH); Nx5/6: rats with 5/6 nephrectomy; Chronic Hyperglycemia: rats receiving Streptozotocin 65 mg/kg; Nx5/6 + IC: rats Nx5/6 received 6 mL/kg of IC; CH + IC: Chronic hyperglycemia rats receiving 6 mL/kg of IC. Renal function (inulin clearance; urinary neutrophil gelatinase-associated lipocalin, NGAL) and hemodynamics (arterial blood pressure; renal blood flow; renal vascular resistance) were evaluated. Iodinated contrast significantly increased urinary NGAL and reduced inulin clearance, while the hemodynamics parameters showed changes in arterial blood pressure, renal blood flow, and renal vascular resistance in both CKD and CH groups. The results suggest that the iodinated contrast in risk factors models has important impact on renal function and hemodynamics. NGAL was confirmed to play a role of highlight in diagnosis of CI-AKI.

    The aim was to undertake a cost-utility analysis of a self-management programme of activity, coping and education (SPACE) for chronic obstructive pulmonary disease (COPD). The analysis was conducted alongside a six-month randomized controlled trial in 30 primary care settings. The economic analysis used data from 184 patients with confirmed diagnosis of COPD, forced expiratory volume in one second/forced vital capacity ratio management programme consisting of an education manual (SPACE for COPD) and consultation or usual care. Six-month costs were estimated from the National Health Service and Personal Social Services perspective and quality-adjusted life years (QALYs) were calculated based on patient responses at baseline and six months.The mean difference in costs between usual care and SPACE FOR COPD programme was -£27.18 (95% confidence interval (CI); -£122.59 to £68.25) while mean difference in QALYs was -0.10 (95% CI; -0.17 to -0.02). The results suggest that the intervention is more costly and more effective than usual care. The probability of the intervention being cost-effective was 97% at a threshold of £20,000/QALY gained. We conclude that the SPACE FOR COPD programme is cost-effective compared to usual care.

    Full Text Available Abstract Impaired kidney function and chronic kidney disease (CKD leading to kidney failure and end-stage renal disease (ESRD is a serious medical condition associated with increased morbidity, mortality, and in particular cardiovascular disease (CVD risk. CKD is associated with multiple physiological and metabolic disturbances, including hypertension, dyslipidemia and the anorexia-cachexia syndrome which are linked to poor outcomes. Specific hormonal, inflammatory, and nutritional-metabolic factors may play key roles in CKD development and pathogenesis. These include raised proinflammatory cytokines, such as interleukin-1 and −6, tumor necrosis factor, altered hepatic acute phase proteins, including reduced albumin, increased C-reactive protein, and perturbations in normal anabolic hormone responses with reduced growth hormone-insulin-like growth factor-1 axis activity. Others include hyperactivation of the renin-angiotensin aldosterone system (RAAS, with angiotensin II and aldosterone implicated in hypertension and the promotion of insulin resistance, and subsequent pharmacological blockade shown to improve blood pressure, metabolic control and offer reno-protective effects. Abnormal adipocytokine levels including leptin and adiponectin may further promote the insulin resistant, and proinflammatory state in CKD. Ghrelin may be also implicated and controversial studies suggest activities may be reduced in human CKD, and may provide a rationale for administration of acyl-ghrelin. Poor vitamin D status has also been associated with patient outcome and CVD risk and may indicate a role for supplementation. Glucocorticoid activities traditionally known for their involvement in the pathogenesis of a number of disease states are increased and may be implicated in CKD-associated hypertension, insulin resistance, diabetes risk and cachexia, both directly and indirectly through effects on other systems including activation of the mineralcorticoid

  7. Dirty electricity, chronic stress, neurotransmitters and disease.

    Dirty electricity, also called electrical pollution, is high-frequency voltage transients riding along the 50 or 60 Hz electricity provided by the electric utilities. It is generated by arcing, by sparking and by any device that interrupts current flow, especially switching power supplies. It has been associated with cancer, diabetes and attention deficit hyperactivity disorder in humans. Epidemiological evidence also links dirty electricity to most of the diseases of civilization including cancer, cardiovascular disease, diabetes and suicide, beginning at the turn of the twentieth century. The dirty electricity level in a public library was reduced from over 10 000 Graham/Stetzer (G/S) units to below 50 G/S units by installing plug-in capacitive filters. Before cleanup, the urinary dopamine level of only one of seven volunteers was within normal levels, while four of seven phenylethylamine levels were normal. After an initial decline, over the next 18 weeks the dopamine levels gradually increased to an average of over 215 μg/g creatinine, which is well above 170 μg/g creatinine, the high normal level for the lab. Average phenylethylamine levels also rose gradually to slightly above 70 μg/g creatinine, the high normal level for the lab. Neurotransmitters may be biomarkers for dirty electricity and other electromagnetic field exposures. We believe that dirty electricity is a chronic stressor of electrified populations and is responsible for many of their disease patterns.

    Cigarran Guldris, Secundino; González Parra, Emilio; Cases Amenós, Aleix

    The intestinal microflora maintains a symbiotic relationship with the host under normal conditions, but its imbalance has recently been associated with several diseases. In chronic kidney disease (CKD), dysbiotic intestinal microflora has been reported with an increase in pathogenic flora compared to symbiotic flora. An enhanced permeability of the intestinal barrier, allowing the passage of endotoxins and other bacterial products to the blood, has also been shown in CKD. By fermenting undigested products that reach the colon, the intestinal microflora produce indoles, phenols and amines, among others, that are absorbed by the host, accumulate in CKD and have harmful effects on the body. These gut-derived uraemic toxins and the increased permeability of the intestinal barrier in CKD have been associated with increased inflammation and oxidative stress and have been involved in various CKD-related complications, including cardiovascular disease, anaemia, mineral metabolism disorders or the progression of CKD. The use of prebiotics, probiotics or synbiotics, among other approaches, could improve the dysbiosis and/or the increased permeability of the intestinal barrier in CKD. This article describes the situation of the intestinal microflora in CKD, the alteration of the intestinal barrier and its clinical consequences, the harmful effects of intestinal flora-derived uraemic toxins, and possible therapeutic options to improve this dysbiosis and reduce CKD-related complications.

    Full Text Available Thyroid hormones play a very important role regulating metabolism, development, protein synthesis, and influencing other hormone functions. The two main hormones produced by the thyroid are triiodothyronine (T3 and thyroxine (T4. These hormones can also have significant impact on kidney disease so it is important to consider the physiological association of thyroid dysfunction in relation to chronic kidney disease (CKD. CKD has been known to affect the pituitary-thyroid axis and the peripheral metabolism of thyroid hormones. Low T3 levels are the most common laboratory finding followed by subclinical hypothyroidism in CKD patients. Hyperthyroidism is usually not associated with CKD but has been known to accelerate it. One of the most important links between thyroid disorders and CKD is uremia. Patients who are appropriately treated for thyroid disease have a less chance of developing renal dysfunction. Clinicians need to be very careful in treating patients with low T3 levels who also have an elevation in TSH, as this can lead to a negative nitrogen balance. Thus, clinicians should be well educated on the role of thyroid hormones in relation to CKD so that proper treatment can be delivered to the patient.

    2016-10-01

    Chronic obstructive pulmonary disease (COPD) is the only major worldwide cause of mortality that is currently increasing in prevalence. Furthermore, COPD is incurable, and the only therapy that has been shown to increase survival is oxygen therapy in selected patients. Compared to patients with cancer, patients with COPD experience similar levels of pain, breathlessness, fatigue, depression, and anxiety and have a worse quality of life but have comparatively little access to palliative care. When these patients do receive palliative care, they tend to be referred later than patients with cancer. Many disease, patient-, and provider-related factors contribute to this phenomenon, including COPD's unpredictable course, misperceptions of palliative care among patients and physicians, and lack of advance care planning discussions outside of crisis situations. A new paradigm for palliative care would introduce palliative treatments alongside, rather than at the exclusion of disease-modifying interventions. This integrated approach would circumvent the issue of difficult prognostication in COPD, as any patient would receive individualized palliative interventions from the time of diagnosis. These points will be covered in this review, which discusses the challenges in providing palliative care to COPD patients, the strategies to mitigate the challenges, management of common symptoms, and the evidence for integrated palliative care models as well as some suggestions for future development.

    Endocrine abnormalities are common in patients with chronic kidney disease (CKD) and lead to sexual dysfunction, anemia, hyperparathyroidism, and altered mineral metabolism. Common clinical problems include disturbances in menstruation in women, erectile dysfunction in men, and decreased libido and infertility in both sexes. Organic factors tend to be prominent and are related to uremia and other comorbid illnesses. Psychological factors and depression may exacerbate the primary problem. Alterations in the hypothalamic-pituitary axis are seen early in CKD and tend to worsen after patients start dialysis. Hypogonadism plays a dominant role in male sexual function, whereas changes in hypothalamic-pituitary function predominate in female sexual dysfunction. In patients on dialysis, treatment strategies include optimizing dose of dialysis, correction of anemia with erythropoietin, and correction of hyperparathyroidism. Successful kidney transplantation may restore normal sexual function, especially in younger patients.

    Exercise training has become a cornerstone of Pulmonary Rehabilitation. Since the nineties, the effectiveness in clinically relevant improvements in exercise capacity and health-related quality of life has been proved. Current guidelines (Evidence A) recommend high intensity continuous exercise for lower extremities as the most effective exercise modality, however, for some patients it is often difficult to initiate such an exercise programme due to the limitation of dyspnoea or leg fatigue. In recent years, special relevance has been given to the integration of other modalities of exercise (continuous versus interval, aerobic versus strength, inclusion or not of respiratory muscle training). The authors carry out a review of the current literature concerning exercise training in chronic pulmonary disease and this highlights the role of tailored exercise to break the vicious cycle of dyspnoea and inactivity.

    Treatment of chronic obstructive pulmonary disease (COPD) has underwent a very important advance in the last five years. It has been developed a new long-lasting anticholynergic drug, tiotrope bromure, which has been found to improve lung function and exercise capacity and to decrease relapses. Also the combined treatment of long lasting beta 2 adrenergics with inhaled steroids (salmeterol/fluticasone and formoterol/budesonide) has proven similar results. However, the response to these new drugs is not the same in all patients. Individual characteristics such as gravity, degree of bronchial hyperresponsiveness, frequency of relapses, comorbidity, etc will determine the response to several agents. Thus, it is necessary to perform a detailed diagnostic study in COPD patients in order to select the best treatment in an individualized form. In the future, new specific antiinflammatories such as phosphodiesterase 4 inhibitors or agents with a potential action in tissue regeneration could lead to new perspectives, as well as to new questions, in COPD treatment.

    Full Text Available Severe growth retardation (below the third percentile for height is seen in up to one-third children with chronic kidney disease. It is thought to be multifactorial and despite optimal medical therapy most children are unable to reach their normal height. Under-nutrition, anemia, vitamin D deficiency with secondary hyperparathyroidism, metabolic acidosis, hyperphosphatemia, renal osteodystrophy; abnormalities in the growth hormone/insulin like growth factor system and sex steroids, all have been implicated in the pathogenesis of growth failure. Therapy includes optimization of nutritional and metabolic abnormalities. Failure to achieve adequate height despite 3-6 months of optimal medical measures mandates the use of recombinant GH (rGH therapy, which has shown to result in catch-up growth, anywhere from 2 cm to 10 cm with satisfactory liner, somatic and psychological development.

    Full Text Available Resilience can be an important factor in health promotion. The aim of the present study was to carry out a review of the literature in the Pubmed and PsycINFO databases, using the descriptors “resilience” and “chronic disease”. The research contemplated publications conducted in the past 20 years from June 1993 to June 2013. Twelve articles that met the inclusion criteria were identified. These articles pointed towards a negative relationship between resilience and depression, anxiety, incapacitation, and somatization, and also found an inverse correlation between resilience scores and the progression of illness (activity of the disease, control of glycemic level, and severity of depression, and an association between resilience and quality of life and health promotional behavior. In conclusion, resilience may influence the process of illness and outcome in health. It is necessary to develop preventive interventions that allow protective factors for resilience to be developed, which could improve the outcomes in health.

    Chronic disease management has been a rapidly growing entity in the 21st century as a strategy for managing chronic illnesses in large populations. However, experience has shown that disease management programs have not been able to demonstrate their financial value. The objectives of disease management programs are to create quality benchmarks, such as principles and guidelines, and to establish a uniform set of metrics and a standardized methodology for evaluating them. In order to illuminate the essence of disease management and its components, as well as the complexity and the problematic nature of performing economic calculations of their profitability and value, we collected data from several reports that dealt with the economic intervention of disease management programs. The disease management economic evaluation is composed of a series of steps, including the following major categories: data/information technology, information generation, assessment/recommendations, actionable customer plans, and program assessment/reassessment. We demonstrate the elements necessary for economic analysis. Disease management is one of the most innovative tools in the managed care environment and is still in the process of being defined. Therefore, objectives should include the creation of quality measures, such as principles and guidelines, and the establishment of a uniform set of metrics and a standardized methodology for evaluating them.

    Full Text Available Objective: The aim of the study was to determine the etiology of Chronic Kidney Disease (CKD among children attending the pediatric nephrology service at Abuzar children's hospital in Ahvaz city, the referral center in Southwest of Iran.Methods: We reviewed the records of 139 children, diagnosed to have CKD over a 10-year period. CKD was defined a glomerular filtration rate (GFR below 60 ml/1.73 m2/min persisting for more than 3 months.Findings: Among 139 children 81 (58% were males. The mean age at diagnosis of CKD in the patients was 4.2 (±3.6 years. Mean level of serum creatinine at presentation was 1.9 (±1.4 mg/dl. The mean GFR at presentation was 33.5 (±15.4 ml/1.73m2/min while 22% of the patients were already at end stage renal failure indicating that these children were referred too late. Congenital urologic malformation was the commonest cause of CKD present in 70 (50.4% children [reflux nephropathy (23.1%, hypo/dysplastic kidney (15.8%, obstructive uropathy (10.8%, and prune belly syndrome (0.7%]. Other causes included hereditary nephropathies (17.2%, chronic glomerulo-nephritis (6.5%, multisystemic diseases (4.3%, miscellaneous and unknown (each one 10.8%. The mean duration of follow-up was 26 (±24.67 months. Peritoneal or hemodialysis was performed in 10 patients. Six patients underwent (4 live-related and 2 non-related renal transplantation. The rest have died or received standard conservative management for CKD.Conclusion: The commonest causes of CKD were reflux nephropathy, hypo/dysplastic kidney, hereditary nephropathy and obstructive uropathy. Patients presented late, had severe CKD and were malnourished and stunted.

    AIM: To investigate the effect of chronic inflammatory bowel disease (CIBD) specific risk factors for cholecystolithiasis,as duration and involvement pattern of the disease and prior surgery in patients with Crohn's disease (CD) and ulcerative colitis (UC).METHODS: A total of 222 patients with CD (135 females,87 males; average age, 35.8±11.8 years; range 17-81 years)and 88 patients with UC (39 females, 49 males; average age, 37.2±13.6 years; range 16-81 years) underwent clinical and ultrasound examinations. Besides age, sex and degree of obesity, patients' CIBD specific parameters, including duration and extent of disease and prior operations were documented and evaluated statistically using logistic regression.RESULTS: The overall prevalence of gallbladder stone disease in patients with CD was 13% (n = 30). Only age could be shown to be an independent risk factor (P = 0.014).Compared to a collective representative for the general population in the same geographic region, the prevalence of cholecystolithiasis was higher in all corresponding age groups. Patients with UC showed an overall prevalence of gallbladder stone disease of only 4.6%.CONCLUSION:Only age but not disease-specific factors such as duration and extent of disease, and prior surgery are independent risk factors for the development of cholecystolithiasis in patients with CIBD.

    Objective . This study aims to highlight the challenges in the diagnosis of hyperparathyroidism (HPT) in patients with advanced chronic kidney disease (CKD). Methods . In this report, we describe a middle-aged Filipino gentleman with underlying CKD who presented with intractable nausea, vomiting, severe and medically refractory hypercalcaemia and parathyroid hormone (PTH) concentrations in excess of 2400 pg/mL. The underlying pathophysiology as well as the aetiologies and current relevant literature are discussed. We also suggest an appropriate diagnostic approach to identify and promptly treat patients with CKD, HPT and hypercalcaemia. Results . Evaluation confirmed the presence of a large parathyroid adenoma; HPT and hypercalcaemia resolved rapidly following resection. Conclusion . This case report is remarkable for its severe hypercalcaemia requiring haemodialysis, large adenoma size, acute-on-chronic kidney injury and markedly elevated PTH concentration in association with primary HPT in CKD.

    Chronic kidney disease (CKD) may affect excretion and metabolism of vitamins but data for dogs are limited. In this study, blood vitamin levels were investigated in 19 dogs with chronic renal failure. High performance liquid chromatography was used to quantify retinol, retinyl esters, tocopherol, thiamine, riboflavin, pyridoxal-5'-phosphate, ascorbic acid and 25-hydroxycholecalciferol concentrations, whereas cobalamin, folate, biotin and pantothenic acid were measured by microbiological methods. Levels of retinol, retinyl palmitate, ascorbic acid, and vitamins B1, B2 and B6 were increased compared to healthy dogs. Dogs with CKD showed decreased concentrations of 25-hydroxycholecalciferol and folate. Alpha-tocopherol, biotin, pantothenate and cobalamin levels were not significantly different between controls and dogs with CKD. Whether lower vitamin D and folate concentrations in dogs with CKD justify supplementation has to be evaluated in future studies.

    Pneumococcal vaccination is still rare in Japan. To evaluate understanding concerning the vaccination, we employed a questionnaire answered by patients aged over 60 with chronic respiratory diseases from August to October 2002. Only 286 (18%) of the 1595 patients already knew of the existence of the vaccine, and 999 (64%) patients wanted to be vaccinated. That season, 717 (43%) patients were actually vaccinated. Patients with chronic respiratory failure, those who had contracted pulmonary infections in the previous year, those over 70 year-old, and male patients tended to be vaccinated. Although elderly and high-risk patients are recommended to be vaccinated, the pneumococcal vaccination rates in those patients was low. Campaigns for vaccination are needed.

  8. Biologic therapies for chronic inflammatory bowel disease

    Directory of Open Access Journals (Sweden)

    M. P. Martínez-Montiel

    Full Text Available Crohn's disease (CD and ulcerative colitis (UC make up the so-called chronic inflammatory bowel disease (IBD. Advances in the understanding of IBD pathophysiologic mechanisms in the last few years have allowed the development of novel therapies such as biologic therapies, which at least theoretically represent a more specific management of this disease with fewer side effects. Currently, the only effective and widely accepted biologic therapy for the treatment of intraluminal, fistulizing CD, both for remission induction and maintenance, is infliximab. The role of other monoclonal antibodies such as adalimumab is not clearly established. It could be deemed an alternative for patients with allergic reactions to infliximab, and for those with lost response because of anti-infliximab antibody development. However, relevant issues such as dosage and administration regimen remain to be established. Anti-integrin α4 therapies, despite encouraging results in phase-3 studies, are still unavailable, as their marketing authorization was held back in view of a number of reports regarding progressive multifocal leukoencephalopathy cases. Immunostimulating therapy may be highly relevant in the near future, as it represents a novel strategy against disease with the inclusion of granulocyte-monocyte colony-stimulating factors. Regarding ulcerative colitis, results from the ACT-1 and ACT-2 studies showed that infliximab is also useful for the management of serious UC flare-ups not responding to standard treatment, which will lead to a revision of therapeutic algorithms, where this drug should be given preference before intravenous cyclosporine. In the next few years, the role of anti-CD3 drugs (vilisilizumab, T-cell inhibiting therapies, and epithelial repair and healing stimulating factors will be established.

    Cardiovascular disease constitutes the major cause of mortality in patients with chronic kidney disease. Arterial stiffness is an important contributor to the occurrence and progression of cardiovascular disease. Various risk factors, including altered hormone levels, have been suggested to be associated with arterial stiffness. Based on the background that chronic kidney disease predisposes individuals to a wide range of hormonal changes, we herein review the available data on the association between arterial stiffness and hormones in patients with chronic kidney disease and summarize the data for the general population.

    Full Text Available Introduction: Chronic obstructive pulmonary disease is characterized by progressive and partially reversible obstruction of pulmonary airflow. Aim: To characterize swallowing in patients with chronic obstructive pulmonary disease and correlate the findings with the degree chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, and smoking. Method: We conducted a prospective cohort study of 19 patients (12 men and 7 women; age range, 50–85 years with confirmed medical diagnosis of chronic obstructive pulmonary disease. This study was performed in 2 stages (clinical evaluation and functional assessment using nasolaryngofibroscopy on the same day. During both stages, vital signs were checked by medical personnel. Results: Clinical evaluation of swallowing in all patients showed the clinical signs of cough. The findings of nasolaryngofibroscopy highlighted subsequent intraoral escape in 5 patients (26.5%. No patient had tracheal aspiration. There was no association of subsequent intraoral escape with degree of chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, or smoking. Conclusion: In patients with chronic obstructive pulmonary disease, there was a prevalence of oral dysphagia upon swallowing and nasolaryngofibroscopy highlighted the finding of subsequent intraoral escape. There was no correlation between intraoral escape and the degree of chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, or smoking.

  13. Building the chronic kidney disease management team.

    2008-01-01

    The need to be efficient and the demands for performance-based service are changing how nephrologists deliver care. Chronic kidney disease (CKD) occurs in patients with complex medical and social problems. CKD management requires that multidisciplinary professionals provide patient education, disease management, and psychosocial support. To remain cost-efficient, many physicians are training and supervising midlevel practitioners in the delivery of specialized health care. Specialized care that meets present CKD patient needs is best delivered in a CKD clinic. Three models of CKD clinic are identified: (1) anemia management CKD clinic, (2) the basic CKD clinic, and (3) the comprehensive CKD clinic. Each clinic model is based on critical elements of staffing, billable services, and patient-focused health care. Billable services are anemia-management services, physician services that may be provided by midlevel practitioners, and medical nutrition therapy. In some cases, social worker services may be billable. Building a patient-focused clinic that offers CKD management requires planning, familiarity with federal regulations and statutes, and skillful practitioners. Making services cost-efficient and outcome oriented requires careful physician leadership, talented midlevel practitioners, and billing professionals who understand the goals of the CKD clinic. As Medicare payment reforms evolve, a well-organized CKD program can be well poised to meet the requirements of payers and congressional mandates for performance-based purchasing.

    The population of microbes (microbiome) in the intestine is a symbiotic ecosystem conferring trophic and protective functions. Since the biochemical environment shapes the structure and function of the microbiome, we tested whether uremia and/or dietary and pharmacologic interventions in chronic kidney disease alters the microbiome. To identify different microbial populations, microbial DNA was isolated from the stools of 24 patients with end-stage renal disease (ESRD) and 12 healthy persons, and analyzed by phylogenetic microarray. There were marked differences in the abundance of 190 bacterial operational taxonomic units (OTUs) between the ESRD and control groups. OTUs from Brachybacterium, Catenibacterium, Enterobacteriaceae, Halomonadaceae, Moraxellaceae, Nesterenkonia, Polyangiaceae, Pseudomonadaceae, and Thiothrix families were markedly increased in patients with ESRD. To isolate the effect of uremia from inter-individual variations, comorbid conditions, and dietary and medicinal interventions, rats were studied 8 weeks post 5/6 nephrectomy or sham operation. This showed a significant difference in the abundance of 175 bacterial OTUs between the uremic and control animals, most notably as decreases in the Lactobacillaceae and Prevotellaceae families. Thus, uremia profoundly alters the composition of the gut microbiome. The biological impact of this phenomenon is unknown and awaits further investigation.

  15. Neurological complications in chronic kidney disease

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available Patients with chronic kidney disease (CKD are frequently afflicted with neurological complications. These complications can potentially affect both the central and peripheral nervous systems. Common neurological complications in CKD include stroke, cognitive dysfunction, encephalopathy, peripheral and autonomic neuropathies. These conditions have significant impact not only on patient morbidity but also on mortality risk through a variety of mechanisms. Understanding the pathophysiological mechanisms of these conditions can provide insights into effective management strategies for neurological complications. This review describes clinical management of neurological complications in CKD with reference to the contributing physiological and pathological derangements. Stroke, cognitive dysfunction and dementia share several pathological mechanisms that may contribute to vascular impairment and neurodegeneration. Cognitive dysfunction and dementia may be differentiated from encephalopathy which has similar contributing factors but presents in an acute and rapidly progressive manner and may be accompanied by tremor and asterixis. Recent evidence suggests that dietary potassium restriction may be a useful preventative measure for peripheral neuropathy. Management of painful neuropathic symptoms can be achieved by pharmacological means with careful dosing and side effect considerations for reduced renal function. Patients with autonomic neuropathy may respond to sildenafil for impotence. Neurological complications often become clinically apparent at end-stage disease, however early detection and management of these conditions in mild CKD may reduce their impact at later stages.

    Fractures across the stages of chronic kidney disease (CKD) could be due to osteoporosis, some form of renal osteodystrophy defined by specific quantitative histomorphometry or chronic kidney disease-mineral and bone disorder (CKD-MBD). CKD-MBD is a systemic disease that links disorders of mineral and bone metabolism due to CKD to either one or all of the following: abnormalities of calcium, phosphorus, parathyroid hormone or vitamin D metabolism; abnormalities in bone turnover, mineralization, volume, linear growth or strength; or vascular or other soft-tissue calcification. Osteoporosis, as defined by the National Institutes of Health, may coexist with renal osteodystrophy or CKD-MBD. Differentiation among these disorders is required to manage correctly the correct disorder to reduce the risk of fractures. While the World Health Organization (WHO) bone mineral density (BMD) criteria for osteoporosis can be used in patients with stages 1-3 CKD, the disorders of bone turnover become so aberrant by stages 4 and 5 CKD that neither the WHO criteria nor the occurrence of a fragility fracture can be used for the diagnosis of osteoporosis. The diagnosis of osteoporosis in stages 4 and 5 CKD is one of the exclusion-excluding either renal osteodystrophy or CKD-MBD as the cause of low BMD or fragility fractures. Differentiations among the disorders of renal osteodystrophy, CKD-MBD or osteoporosis are dependent on the measurement of specific biochemical markers, including serum parathyroid hormone (PTH) and/or quantitative bone histomorphometry. Management of fractures in stages 1-3 CKD does not differ in persons with or without CKD with osteoporosis assuming that there is no evidence for CKD-MBD, clinically suspected by elevated PTH, hyperphosphatemia or fibroblast growth factor 23 due to CKD. Treatment of fractures in persons with osteoporosis and stages 4 and 5 CKD is not evidence-based, with the exception of post-hoc analysis suggesting efficacy and safety of specific

    We evaluated the specificity and clinical relevance of anti-hepatitis C virus antibody positivity in 22 HBsAg-negative patients with autoimmune (anti-nuclear, anti-actin or anti-liver-kidney microsomal antibody positive) chronic active hepatitis. An ELISA anti-HCV test and a recombinant immunoblot assay (RIBA-HCV) were used. Thirteen patients (59%) were anti-HCV positive and five (23%) anti-HCV negative by both ELISA and RIBA-HCV tests. Four patients (18%) were borderline positive by ELISA (OD less than 1.0), and three of them (all with severe disease) were negative by RIBA. Histologic necroinflammation, AST/ALT and gamma-globulins levels were higher and response to prednisolone treatment was better in RIBA anti-HCV-negative than in anti-HCV-positive cases. We confirmed with both RIBA and ELISA tests the high prevalence of anti-HCV already reported by ELISA in anti-nuclear and anti-liver-kidney microsomal antibody positive chronic active hepatitis. False positive for anti-HCV (i.e., a positive ELISA test not confirmed by RIBA) occurred only among patients with severe disease. Since RIBA-negative subjects showed the best response to corticosteroid, they might represent the only subset of cases of 'true' autoimmune chronic active hepatitis.

  19. SOCS1 Mimetic Peptide Suppresses Chronic Intraocular Inflammatory Disease (Uveitis

    Directory of Open Access Journals (Sweden)

    Chang He

    2016-01-01

    Full Text Available Uveitis is a potentially sight-threatening disease characterized by repeated cycles of remission and recurrent inflammation. The JAK/STAT pathway regulates the differentiation of pathogenic Th1 and Th17 cells that mediate uveitis. A SOCS1 mimetic peptide (SOCS1-KIR that inhibits JAK2/STAT1 pathways has recently been shown to suppress experimental autoimmune uveitis (EAU. However, it is not clear whether SOCS1-KIR ameliorated uveitis by targeting JAK/STAT pathways of pathogenic lymphocytes or via inhibition of macrophages and antigen-presenting cells that also enter the retina during EAU. To further investigate mechanisms that mediate SOCS1-KIR effects and evaluate the efficacy of SOCS1-KIR as an investigational drug for chronic uveitis, we induced EAU in rats by adoptive transfer of uveitogenic T-cells and monitored disease progression and severity by slit-lamp microscopy, histology, and optical coherence tomography. Topical administration of SOCS1-KIR ameliorated acute and chronic posterior uveitis by inhibiting Th17 cells and the recruitment of inflammatory cells into retina while promoting expansion of IL-10-producing Tregs. We further show that SOCS1-KIR conferred protection of resident retinal cells that play critical role in vision from cytotoxic effects of inflammatory cytokines by downregulating proapoptotic genes. Thus, SOCS1-KIR suppresses uveitis and confers neuroprotective effects and might be exploited as a noninvasive treatment for chronic uveitis.

    Youth, which is forgiven everything, forgives itself nothing: age, which forgives itself everything, is forgiven nothing. George Bernard Shaw The proportion of older people in the general population is steadily increasing worldwide, with the most rapid growth in low-and middle-income countries [1]. This demographic change is to be celebrated, because it is the consequence of socioeconomic development and better life expectancy. However, population aging also has important implications for society - in diverse areas including health systems, labor markets, public policy, social programs, and family dynamics [2]. A successful response to the aging population will require capitalizing on the opportunities that this transition offers, as well as effectively addressing its challenges. Chronic kidney disease (CKD) is an important public health problem that is characterized by poor health outcomes and very high health care costs. CKD is a major risk multiplier in patients with diabetes, hypertension, heart disease and stroke - all of which are key causes of death and disability in older people [3]. Since the prevalence of CKD is higher in older people, the health impact of population aging will depend in part on how the kidney community responds. March 13, 2014 will mark the celebration of the 9th World Kidney Day (WKD), an annual event jointly sponsored by the International Society of Nephrology and the International Federation of Kidney Foundations. Since its inception in 2006, WKD has become the most successful effort to raise awareness among policymakers and the general public about the importance of kidney disease. The topic for WKD 2014 is "CKD in older people". This article reviews the key links between kidney function, age, health and illness - and discusses the implications of the aging population for the care of people with CKD.

    Delzell, John E

    2013-06-01

    The etiology of chronic obstructive pulmonary disease (COPD) is chronic lung inflammation. In the United States, this inflammation most commonly is caused by smoking. COPD is diagnosed when an at-risk patient presents with respiratory symptoms and has irreversible airway obstruction indicated by a forced expiratory volume in 1 second/forced vital capacity ratio of less than 0.7. Management goals for COPD include smoking cessation, symptom reduction, exacerbation reduction, hospitalization avoidance, and improvement of quality of life. Stable patients with COPD who remain symptomatic despite using short-acting bronchodilators should start inhaled maintenance drugs to reduce symptoms and exacerbations, avoid hospitalizations, and improve quality of life. A long-acting anticholinergic or a long-acting beta2-agonist (LABA) can be used for initial therapy; these drugs have fewer adverse effects than inhaled corticosteroids (ICS). If patients remain symptomatic despite monotherapy, dual therapy with a long-acting anticholinergic and a LABA, or a LABA and an ICS, may be beneficial. Triple therapy (ie, a long-acting anticholinergic, a LABA, and an ICS) also is used, but it is unclear if triple therapy is superior to dual therapy. Roflumilast, an oral selective inhibitor of phosphodiesterase 4, is used to manage moderate to severe COPD. Continuous oxygen therapy is indicated for patients with COPD who have severe hypoxemia (ie, PaO2 less than 55 mm Hg or an oxygen saturation less than 88% on room air). Nonpharmacologic strategies also are useful to improve patient outcomes. Pulmonary rehabilitation improves dyspnea and quality of life. Pulmonary rehabilitation after an acute exacerbation reduces hospitalizations and mortality, and improves quality of life and exercise capacity. Smoking cessation is the most effective management strategy for reducing morbidity and mortality in patients with COPD. Lung volume reduction surgery, bullectomy, and lung transplantation are

    Full Text Available Aim: The purpose of our study is to study the etiopathogenesis of periodontitis in chronic kidney disease and to identify a correlation between periodontitis and chronic kidney disease, with the help of periodontal exaamination, ultrasonographic and hematobiochemical analysis. Materials and Methods: 46 dogs with renal failure were studied and classified as presenting a slight (56.52%, moderate (36.95% and severe (47.8% degree of periodontal disease. Results: Marked gingival recession involving whole maxillary dental arcade, Oral mucosa ulcers and tissue necrosis and mobility of mandibular incisors was observed in dogs with chronic kidney disease. Dogs with normal renal function were observed to have minimal gingival recession of the mandibular teeth only. Conclusion: In view of the causative association between periodontal infection, generalized inflammation and important systemic diseases like chronic kidney disease, we hypothesize that targeted prophylaxis and careful treatment of oral diseases can prevent the progression of renal failure

  13. Rethinking global health challenges: towards a 'global compact' for reducing the burden of chronic disease.

    Chronic diseases, including cardiovascular disease, diabetes and cancer, are the leading cause of death and disability in both the developed and developing world (excluding sub-Saharan Africa). At present, the global framework for action on chronic disease is strongly 'World Health Organization (WHO)-centric', defined by two WHO initiatives: the WHO Framework Convention on Tobacco Control, and the Global Strategy on Diet, Physical Activity and Health. This paper explores the difficulties of developing a collective response to global health challenges, and draws out some implications for chronic disease. It highlights how political partnerships and improved governance structures, economic processes, and international laws and standards function as three, concurrent pathways for encouraging policy implementation at country level and for building collective commitment to address the transnational determinants of chronic disease. The paper evaluates WHO's initiatives on chronic disease in terms of these pathways, and makes the case for a global compact on chronic disease as a possible structure for advancing WHO's free-standing goal of reducing mortality from chronic diseases by an additional 2% between 2005 and 2015. Beneath this overarching structure, the paper argues that global agencies, donor governments and other global health stakeholders could achieve greater impact by coordinating their efforts within a series of semi-autonomous 'policy channels' or 'workstreams'. These workstreams - including trade and agriculture, consumer health issues and workplace health promotion - could act as focal points for international cooperation, drawing in a wider range of health stakeholders within their areas of comparative advantage.

    Atherosclerosis is a major cause of mortality and morbidity among hemodialysis patients, but whether it is more severe in hemodialysis patients than in cardiovascular disease patients without chronic kidney disease is unclear. We examined 46 autopsy patients who had undergone hemodialysis, and age and sex-matched 46 patients with cardiovascular disease and an eGFR of >60 mL/min/1.73 m(2). There was no difference in the prevalence of diabetes or hypertension between the groups. We divided the aorta into four segments: A, ascending artery to arch; B, descending artery to diaphragm; C, suprarenal; and D, infrarenal. We used the classification of the American Heart Association to evaluate atherosclerosis progression. Distribution was scored by the extent to which each segment was damaged: 0, none; 1, less than 1/3; 2, more than 1/3 to less than 2/3; 3, more than 2/3. Histological examination revealed that the progression score (P 60 mL/min/1.73 m(2). Aortic atherosclerosis was aggravated by traditional and chronic kidney disease-related risk factors.

    Chronic non-communicable disease is a major public health problem affecting the health of residents in china. Evidence shows that, in addition to four major risk factors, i.e. unreasonable dietary, lack of physical activity, smoking and drinking, epidemic and severe outcome of chronic disease is associated with many infectious diseases. Increasingly cancers have been shown to have an infectious etiology. There is also a significantly increased risk of infectious disease such as influenza, pneumonia and other infectious disease in people with pre-existing chronic non-communicable diseases like diabetes, heart disease, and lung diseases. And more than that, there is a high risk of susceptibility to death and severe outcomes among them. Epidemiological studies has confirmed, that through targeted vaccine inoculation, liver cancer, cervical cancer can be effectively prevented, while influenza or pneumonia vaccine are related to reduced risk of hospitalization or death and hospitalization expenses regarding with a variety of chronic diseases. World Health Organization and several other professional organizations have put forward recommendations on vaccine inoculation of chronic disease patients. Programs targeting infectious factors are also an important aspect of chronic diseases prevention and control, therefore, related researches need to be strengthened in the future.

  16. Metabolic Disturbances in Children with Chronic Liver Disease

    Full Text Available Introduction: Liver disease results in complex pathophysiologic disturbances affecting nutrient digestion, absorption, distribution, storage, and use. This article aimed to present a classification of metabolic disturbances in chronic liver disease in children?   Materials and Methods: In this review study databases including proquest, pubmedcentral, scincedirect, ovid, medlineplus were been searched with keyword words such as” chronic liver disease"  ” metabolic disorder””children” between 1999 to 2014. Finally, 8 related articles have been found.   Results: Metabolic disorder in this population could be categorized in four set: 1carbohydrates, 2proteins,3 fats and 4vitamins. 1 Carbohydrates: Children with CLD are at increased risk for fasting hypoglycemia, because the capacity for glycogen storage and gluconeogenesis is reduced as a result of abnormal hepatocyte function and loss of hepatocyte mass. 2 Proteins: The liver’s capacity for plasma protein synthesis is impaired by reduced substrate availability, impaired hepatocyte function, and increased catabolism. This results in hypoalbuminemia, leading to peripheral edema and contributing to ascites. Reduced synthesis of insulin-like growth factor (IGF-1 and its binding protein IGF-BP3 by the chronically diseased liver results in growth hormone resistance and may contribute to the poor growth observed in these children. 3 Fats: There is increased fat oxidation in children with end-stage liver disease in the fed and fasting states compared with controls, which is probably related to reduced carbohydrate availability. The increased lipolysis results in a decrease in fat stores, which may not be easily replenished in the setting of the fat malabsorption that accompanies cholestasis. Reduced bile delivery to the gut results in impaired fat emulsification, and hence digestion. The products of fat digestion are also poorly absorbed, because bile is also required for micelle formation

    2004-04-01

    Evidence regarding the outcomes of viral super-infection in patients with chronic liver disease and practical strategies for hepatitis A and B vaccination of these individuals are reviewed. Patients with acute hepatitis A and chronic hepatitis B have a more severe clinical course and a higher death rate compared with otherwise healthy individuals with hepatitis A, and these differences are most pronounced in older patients and those with histological evidence of chronic hepatitis or cirrhosis, rather than in asymptomatic hepatitis B carriers. Patients with acute hepatitis A super-infection and chronic hepatitis C have an increased risk of fulminant hepatitis and death. In addition, patients with other chronic liver diseases also appear to be at increased risk for more severe disease with superimposed hepatitis A. Patients with chronic hepatitis B and hepatitis C virus co-infection have more severe laboratory abnormalities, more severe histological disease, a greater frequency of cirrhosis and complications of cirrhosis, and a higher incidence of hepatocellular carcinoma. Vaccines for both hepatitis A and B are safe and effective if used early in the course of chronic liver disease. Hepatitis A and B vaccination should be part of the routine management of patients with chronic liver disease, preferably as early as possible in the natural course of their disease.

    Fractures across the stages of chronic kidney disease (CKD) could be due to osteoporosis, some form of renal osteodystrophy defined by specific quantitative histomorphometry or chronic kidney disease–mineral and bone disorder (CKD–MBD). CKD–MBD is a systemic disease that links disorders of mineral and bone metabolism due to CKD to either one or all of the following:abnormalities of calcium, phosphorus, parathyroid hormone or vitamin D metabolism;abnormalities in bone turnover, mineralization, volume, linear growth or strength;or vascular or other soft-tissue calcification. Osteoporosis, as defined by the National Institutes of Health, may coexist with renal osteodystrophy or CKD–MBD. Differentiation among these disorders is required to manage correctly the correct disorder to reduce the risk of fractures. While the World Health Organization (WHO) bone mineral density (BMD) criteria for osteoporosis can be used in patients with stages 1–3 CKD, the disorders of bone turnover become so aberrant by stages 4 and 5 CKD that neither the WHO criteria nor the occurrence of a fragility fracture can be used for the diagnosis of osteoporosis. The diagnosis of osteoporosis in stages 4 and 5 CKD is one of the exclusion—excluding either renal osteodystrophy or CKD–MBD as the cause of low BMD or fragility fractures. Differentiations among the disorders of renal osteodystrophy, CKD–MBD or osteoporosis are dependent on the measurement of specific biochemical markers, including serum parathyroid hormone (PTH) and/or quantitative bone histomorphometry. Management of fractures in stages 1–3 CKD does not differ in persons with or without CKD with osteoporosis assuming that there is no evidence for CKD–MBD, clinically suspected by elevated PTH, hyperphosphatemia or fibroblast growth factor 23 due to CKD. Treatment of fractures in persons with osteoporosis and stages 4 and 5 CKD is not evidence-based, with the exception of post-hoc analysis suggesting efficacy and

    2014-01-01

    Full Text Available Chronic obstructive pulmonary disease (COPD is a chronic, progressive lung disease resulting from exposure to cigarette smoke, noxious gases, particulate matter, and air pollutants. COPD is exacerbated by acute inflammatory insults such as lung infections (viral and bacterial and air pollutants which further accelerate the steady decline in lung function. The chronic inflammatory process in the lung contributes to the extrapulmonary manifestations of COPD which are predominantly cardiovascular in nature. Here we review the significant burden of cardiovascular disease in COPD and discuss the clinical and pathological links between acute exacerbations of COPD and cardiovascular disease.

    We describe a case of a 9-year-old girl who presented chronic urticaria associated with celiac disease. The prevalence of the manifestation of chronic urticaria in celiac disease is unknown but increase in atopic immunologic disorders has been reported in the setting of gluten enteropathy. Relationship between the clinical manifestations is not clear. The present case of subclinical celiac disease diagnosis in an otherwise asymptomatic child with chronic urticaria further reinforces the evidence that differential for celiac disease warrants to be always considered in children with refractory urticaria.

    Advances in the management of children with chronic liver disease have enabled many to survive into adulthood with or without their native livers, so that the most common of these conditions are becoming increasingly common in adult hepatology practice. Because the aetiologies of chronic liver disease in children may vary significantly from those in adulthood, adults with paediatric-onset chronic liver disease may often present with clinical manifestations unfamiliar to their adulthood physician. Transition of medical care to adult practice requires that the adulthood medical staff (primary physicians and subspecialists) have a comprehensive knowledge of childhood liver disease and their implications, and of the differences in caring for these patients. Pending still unavailable Scientific Society guidelines, this article examines causes, presentation modes, evaluation, management, and complications of the main paediatric-onset chronic liver diseases, and discusses key issues to aid in planning a program of transition from paediatric to adult patients.

    Background A pharmacokinetic study in an Asian population showed that tiotropium 5 μg via Respimat leads to the same plasma levels compared to 18 μg via HandiHaler.The objective of the trial was to compare the efficacy and safety of longterm treatment (1 year) with tiotropium bromide (5 μg) via Respimat(R) with placebo in patients with chronic obstructive pulmonary disease (COPD).Methods A total of 3991 patients were randomized in this double-blind,placebo controlled,parallel group study,while in China 338 patients (309 males,29 females) received either tiotropium bromide (n=167) or placebo (n=171).Tiotropium bromide solution or matching placebo was delivered via Respimat(R) at a dosage of 5 μg (2 x 2.5 μg/puff) once daily for 48 weeks.Co-primary endpoints were trough forced expiratory volume in one second (FEV1) and the time to first exacerbation.Results Statistically significant improvements in trough FEV1 and trough forced vital capacity (FVC) in the tiotropium group were achieved at weeks 4,24,and 48 compared with those in the placebo group.A statistically significant difference (P=0.0027) in favour of tiotropium was also observed for the time to first exacerbation.The total numbers of exacerbations during treatment were 90 and 128 in the tiotropium and placebo groups,respectively,with a rate ratio of 0.69 (P=0.0164).The difference between the treatment groups in the adjusted mean changes from baseline of St.George Respiratory Questionnaire (SGRQ) total score was-3.9 (95% Cl:-7.5,-0.2) and was of statistical significance (P=0.0367).The incidences of serious adverse events (SAEs) in the tiotropium and placebo groups were 16.2% and 17.0%,respectively.Seven deaths occurred whilst patients were on treatment,four in the tiotropium group and three in the placebo group,all of which were assessed as non-related study drugs by the investigators.Conclusions Tiotropium significantly improved lung function and quality of life,delayed the time to first

    Full Text Available Theodore G Liou, Sanjeev M Raman, Barbara C CahillDivision of Respiratory, Critical Care and Occupational Pulmonary Medicine, Department of Medicine, School of Medicine, University of Utah, Salt Lake City, Utah, USAAbstract: Patients with end-stage chronic obstructive pulmonary disease (COPD comprise the largest single lung disease group undergoing transplantation. Selection of appropriate candidates requires consideration of specific clinical characteristics, prognosis in the absence of transplantation, and likely outcome of transplantation. Increased availability of alternatives to transplantation for end-stage patients and the many efforts to increase the supply of donor organs have complicated decision making for selecting transplant candidates. Many years of technical and clinical refinements in lung transplantation methods have improved survival and quality of life outcomes. Further advances will probably come from improved selection methods for the procedure. Because no prospective trial has been performed, and because of confounding and informative censoring bias inherent in the transplant selection process in studies of the existing experience, the survival effect of lung transplant in COPD patients remains undefined. There is a lack of conclusive data on the impact of lung transplantation on quality of life. For some patients with end-stage COPD, lung transplantation remains the only option for further treatment with a hope of improved survival and quality of life. A prospective trial of lung transplantation is needed to provide better guidance concerning survival benefit, resource utilization, and quality of life effects for patients with COPD.Keywords: outcomes, emphysema, COPD, alpha-1-antitrypsin deficiency, survival, single lung transplant, bilateral sequential single lung transplant, lung volume reduction, referral, guidelines, health related quality of life

  7. Thiazide diuretics in advanced chronic kidney disease.

    Chronic kidney disease (CKD) is prevalent in 3%-4% of the adult population in the United States, and the vast majority of these people are hypertensive. Compared with those with essential hypertension, hypertension in CKD remains poorly controlled despite the use of multiple antihypertensive drugs. Hypervolemia is thought to be a major cause of hypertension, and diuretics are useful to improve blood pressure control in CKD. Non-osmotic storage of sodium in the skin and muscle may be a novel mechanism by which sodium may modulate hypertension; further work is need to study this novel phenomenon with diuretics. Among people with stage 4 CKD, loop diuretics are recommended over thiazides. Thiazide diuretics are deemed ineffective in people with stage 4 CKD. Review of the literature suggests that thiazides may be useful even among people with advanced CKD. They cause a negative sodium balance, increasing sodium excretion by 10%-15% and weight loss by 1-2 kg in observational studies. Observational data show improvement in seated clinic blood pressure of about 10-15 mm Hg systolic and 5-10 mm Hg diastolic, whereas randomized trials show about 15 mm Hg improvement in mean arterial pressure. Volume depletion, hyponatremia, hypokalemia, hypercalcemia, and acute kidney injury are adverse effects that should be closely monitored. Our review suggests that adequately powered randomized trials are needed before the use of thiazide diuretics can be firmly recommended in those with advanced CKD.

    Widely prevalent in the general population, chronic kidney disease (CKD) is frequently complicated with hypertension. Control of hypertension in this high-risk population is a major modifiable cardiovascular and renal risk factor but often requires multiple medications. Although thiazides are an attractive agent, guidelines have previously recommended against thiazide use in stage 4 CKD. We review the updated guidelines on thiazide use in advanced CKD, the antihypertensive mechanism of thiazides, and the clinical studies of thiazides in CKD. Older uncontrolled studies have shown that metolazone reduces blood pressure in CKD, but more recently small randomized controlled trials of hydrochlorothiazide in CKD have shown significant improvement in mean arterial pressure of 15 mmHg. Two recent uncontrolled studies of chlorthalidone including one that used ambulatory blood pressure monitoring found significant improvements in blood pressure. These findings all suggest that thiazides may be efficacious even in advanced CKD; however, electrolyte abnormalities were common in the studies reviewed so close monitoring is necessary during use. Adequately powered randomized trials are now needed before the routine use of thiazide diuretics in advanced CKD can be recommended.

    Detection of early chronic obstructive pulmonary disease (COPD) in patients presenting with respiratory symptoms is recommended; however, diagnosing COPD is difficult because a single gold standard is not available. The aim of this article is to review and interpret the existing evidence, theories and consensus on the individual parts of the diagnostic work-up for COPD. Relevant articles are discussed under the subheadings: history taking, physical examination, spirometry and additional lung function assessment. Wheezing, cough, phlegm and breathlessness on exertion are suggestive signs for COPD. The diagnostic value of the physical examination is limited, except for auscultated pulmonary wheezing or reduced breath sounds, increasing the probability of COPD. Spirometric airflow obstruction after bronchodilation, defined as a lowered ratio of the forced volume in one second to the forced vital capacity (FEV1/FVC ratio), is a prerequisite, but can only confirm COPD in combination with suggestive symptoms. Different thresholds are being recommended to define low FEV1/FVC, including a fixed threshold, and one varying with gender and age; however, the way physicians interpret these thresholds in their assessment is not well known. Body plethysmography allows a more complete assessment of pulmonary function, providing results on the total lung capacity and the residual volume and is indicated when conventional spirometry results are inconclusive. Chest radiography has no diagnostic value for COPD but is useful to exclude alternative diagnoses such as heart failure or lung cancer. Extensive history taking is of key importance in diagnosing COPD.

    The evidence continues to mount that Chronic Lyme Disease (CLD) exists and must be addressed by the medical community if solutions are to be found. Four National Institutes of Health (NIH) trials validated the existence and severity of CLD. Despite the evidence, there are physicians who continue to deny the existence and severity of CLD, which can hinder efforts to find a solution. Recognizing CLD could facilitate efforts to avoid diagnostic delays of two years and durations of illness of 4.7 to 9 years described in the NIH trials. The risk to society of emerging antibiotic-resistant organisms should be weighed against the societal risks associated with failing to treat an emerging population saddled with CLD. The mixed long-term outcome in children could also be examined. Once we accept the evidence that CLD exists, the medical community should be able to find solutions. Medical professionals should be encouraged to examine whether: (1) innovative treatments for early LD might prevent CLD, (2) early diagnosis of CLD might result in better treatment outcomes, and (3) more effective treatment regimens can be developed for CLD patients who have had prolonged illness and an associated poor quality of life.

    Chronic Non-Communicable Diseases are the main source of disease burden in Brazil. In 2011, the Brazilian Ministry of Health launched the Strategic Plan of Action for Management of Chronic Non-Communicable Diseases focusing on population-based interventions to manage cardiovascular diseases, diabetes, cancer, and chronic respiratory diseases mainly through fighting tobacco use, unhealthy diets, physical inactivity and the harmful use of alcohol. Although a significant number of scientific studies on chronic diseases and their risk factors have been undertaken in Brazil, few are of cohort design. In this context, the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a cohort study of 15,105 Brazilian public servants reflects the reality of high prevalences of diabetes, hypertension and the main chronic diseases risk factors. The diversity of information that the Study will produce can provide important input to better understand the causes of chronic diseases and to support public policies for fighting them.

    Full Text Available Abstract Background Total cholesterol (TC concentration is the most commonly used measure of statin efficacy in the UK. This study aimed to evaluate the effectiveness of statins in lowering TC, cardiovascular events (CV and mortality five common chronic diseases (chronic obstructive pulmonary disease (COPD, osteoarthritis (OA, rheumatoid arthritis (RA, chronic kidney disease (CKD, and diabetes mellitus (DM and to compare effectiveness with the rest of the population not recorded as having these diseases. Methods A population-based cohort study was conducted in Tayside population who had at least two TC measurements between 1993 and 2007. There were 12,140 patients with chronic diseases and 9,481 patients in the rest of the population not recorded as having these chronic diseases. The main outcomes were TC change from baseline, CV events and all-cause mortality. Results Statin-associated TC reductions varied from 15% to 28% with baseline value of between 5.1 and 5.9 mmol/L in the primary prevention (PP and from 7% to 23% with baseline value of 4.5 to 5.2 mmol/L in the secondary prevention (SP among chronic diseases patients. In the rest of the population, TC reductions with statins were 31% in PP and 28% in SP with baselines of 6.3 mmol/L and 5.3 mmol/L, respectively (test of heterogeneity with chronic disease groups: p  0.05. Conclusions The effectiveness of statins in common chronic diseases varied. With the exception of diabetes, statins tends to be less effective in patients with the chronic diseases compared with the rest of the study population. Changes in TC with statins appear not to correlate well with the changes in cardiovascular events and all-cause mortality.

    Diabetic nephropathy is the leading cause of end-stage chronic kidney disease in most developed countries. Hyperglycemia, hypertension and genetic predisposition are the main risk factors for the development of diabetic nephropathy. Elevated serum lipids, smoking habits, and the amount and origin of dietary protein also seem to play a role as risk factors. Clinical picture includes a progressive increase in albuminuria, decline in glomerular filtration, hypertension, and a high risk of cardiovascular morbidity and mortality. Screening for albuminuria should be performed yearly, starting 5 years after diagnosis in type 1 diabetes or earlier in the presence of adolescence or poor metabolic control. In patients with type 2 diabetes, screening should be performed at diagnosis and yearly thereafter. Patients with albuminuria should undergo evaluation regarding the presence of associated comorbidities, especially retinopathy and macrovascular disease.

    Full Text Available The Framingham Risk Score (FRS was developed to predict coronary heart disease in various populations, and it tended to under-estimate the risk in chronic kidney disease (CKD patients. Our objectives were to determine whether FRS was associated with cardiovascular events, and to evaluate the role of new risk markers and echocardiographic parameters when they were added to a FRS model. This study enrolled 439 CKD patients. The FRS is used to identify individuals categorically as "low" (4.7 cm, left ventricular hypertrophy or left ventricular ejection fraction<50% to the FRS model significantly improves the predictive values for cardiovascular events. In CKD patients, "high" risk categorized by FRS predicts cardiovascular events. Novel biomarkers and echocardiographic parameters provide additional predictive values for cardiovascular events. Future study is needed to assess whether risk assessment enhanced by using these biomarkers and echocardiographic parameters might contribute to more effective prediction and better care for patients.

    Chronic inflammation is a risk factor for many different diseases. It is clear that inflammation is associated with degenerative brain diseases, obesity, metabolic syndrome, cardiovascular disease, diabetes, and cancer. Throughout the past 100 years, changes in the causes of death in the US have been dramatic. The most recent data indicate that cardiovascular disease and cancer are now responsible for 63% of mortality in the US population. Although progression of these diseases is related to diet, lifestyle, and genetic factors, a common but often unrecognized link is the presence of underlying chronic inflammation. As of 2014, 83.6 million people were living with some form of cardiovascular disease, 29.1 million people have been diagnosed with diabetes, 14 million people carried the diagnosis of cancer, and 5.2 million people were living with Alzheimer disease. These diseases are a huge burden on our health care system and all have been associated with chronic inflammation.

  19. The global burden of periodontal disease: towards integration with chronic disease prevention and control.

    2012-10-01

    Chronic diseases are accelerating globally, advancing across all regions and pervading all socioeconomic classes. Unhealthy diet and poor nutrition, physical inactivity, tobacco use, excessive use of alcohol and psychosocial stress are the most important risk factors. Periodontal disease is a component of the global burden of chronic disease, and chronic disease and periodontal disease have the same essential risk factors. In addition, severe periodontal disease is related to poor oral hygiene and to poor general health (e.g. the presence of diabetes mellitus and other systemic diseases). The present report highlights the global burden of periodontal disease: the ultimate burden of periodontal disease (tooth loss), as well as signs of periodontal disease, are described from World Health Organization (WHO) epidemiological data. High prevalence rates of complete tooth loss are found in upper middle-income countries, whereas the tooth-loss rates, at the time of writing, are modest for low-income countries. In high-income countries somewhat lower rates for edentulism are found when compared with upper middle-income countries. Around the world, social inequality in tooth loss is profound within countries. The Community Periodontal Index was introduced by the WHO in 1987 for countries to produce periodontal health profiles and to assist countries in the planning and evaluation of intervention programs. Globally, gingival bleeding is the most prevalent sign of disease, whereas the presence of deep periodontal pockets (≥6 mm) varies from 10% to 15% in adult populations. Intercountry and intracountry variations are found in the prevalence of periodontal disease, and these variations relate to socio-environmental conditions, behavioral risk factors, general health status of people (e.g. diabetes and HIV status) and oral health systems. National public health initiatives for the control and prevention of periodontal disease should include oral health promotion and

    Gopalan, Deepa; Blanchard, Daniel; Auger, William R

    2016-07-01

    Pulmonary hypertension is defined by a mean pulmonary artery pressure greater than 25 mm Hg. Chronic thromboembolic pulmonary hypertension (CTEPH) is defined as pulmonary hypertension in the presence of an organized thrombus within the pulmonary vascular bed that persists at least 3 months after the onset of anticoagulant therapy. Because CTEPH is potentially curable by surgical endarterectomy, correct identification of patients with this form of pulmonary hypertension and an accurate assessment of surgical candidacy are essential to provide optimal care. Patients most commonly present with symptoms of exertional dyspnea and otherwise unexplained decline in exercise capacity. Atypical chest pain, a nonproductive cough, and episodic hemoptysis are observed less frequently. With more advanced disease, patients often develop symptoms suggestive of right ventricular compromise. Physical examination findings are minimal early in the course of this disease, but as pulmonary hypertension progresses, may include nonspecific finding of right ventricular failure, such as a tricuspid regurgitation murmur, pedal edema, and jugular venous distention. Chest radiographs may suggest pulmonary hypertension, but are neither sensitive nor specific for the diagnosis. Radioisotopic ventilation-perfusion scanning is sensitive for detecting CTEPH, making it a valuable screening study. Conventional catheter-based pulmonary angiography retains an important role in establishing the presence and extent of chronic thromboembolic disease. However, computed tomographic and magnetic resonance imaging are playing a growing diagnostic role. Innovative technologies such as dual-energy computed tomography, dynamic contrast-enhanced magnetic resonance imaging, and optical coherence tomography show promise for contributing diagnostic information and assisting in the preoperative characterization of patients with CTEPH.

    terminology is CKDmfo, a name that also indicates the need for multi-disciplinary research programs to facilitate identifying the cause(s) and the need for multiple approaches to eradicate it. While some potential causes remain to be investigated, existing data point to polluted water as the main source of this disease. This article evaluates pros and cons of each hypothesis and highlights the importance of among others, providing clean water to all affected and surrounding communities. Available data do not support any of the postulated agents, chemicals, heavy metals, fluoride, salinity/ionicity, or individual agrochemical components, such as phosphate or glyphosate, as causative factors for CKDmfo in Sri Lanka. However, as the CKDmfo name implies, a combination of these factors (or an unknown toxin) together with harmful behaviour and chronic dehydration may cause this disease. Irrespective of the cause, prevention is the only way forward for eradication.

  2. Endomorphins as agents for the treatment of chronic inflammatory disease.

    Science.gov (United States)

    Jessop, David S

    2006-01-01

    Endomorphin (EM)-1 and EM-2 are tetrapeptides located within the mammalian central nervous system and immune tissues, with high affinity and specificity for micro-opioid receptors. Most of the literature has focused on the analgesic properties of EM-1 and EM-2 in animal models of neuropathic or neurogenic pain, but there is persuasive evidence emerging that EMs can also exert potent anti-inflammatory effects in both acute and chronic peripheral inflammation. The purpose of this review is to present and evaluate the evidence for anti-inflammatory properties of EM-1 and EM-2 with a view to their potential for use in chronic human inflammatory disease. Distribution of EMs within the immune system and functional roles as immunomodulatory agents are summarized and discussed. Possible milestones to be met revolve around issues of peptide stability, biodegradability problems and optimal route and method of delivery. The potential for delivery of a low-cost drug with both peripheral anti-inflammatory and analgesic properties, effective in low doses, and targeted to the site of inflammation, should focus our attention on further development of EMs as potent therapeutic agents in chronic inflammation.

    Infection with West Nile virus (WNV) leads to a range of disease outcomes, including chronic infection, though lack of a robust mouse model of chronic WNV infection has precluded identification of the immune events contributing to persistent infection. Using the Collaborative Cross, a population of recombinant inbred mouse strains with high levels of standing genetic variation, we have identified a mouse model of persistent WNV disease, with persistence of viral loads within the brain. Compared to lines exhibiting no disease or marked disease, the F1 cross CC(032x013)F1 displays a strong immunoregulatory signature upon infection that correlates with restraint of the WNV-directed cytolytic response. We hypothesize that this regulatory T cell response sufficiently restrains the immune response such that a chronic infection can be maintained in the CNS. Use of this new mouse model of chronic neuroinvasive virus will be critical in developing improved strategies to prevent prolonged disease in humans. PMID:27806117

  4. Chronic Lyme disease: the controversies and the science.

    Science.gov (United States)

    Lantos, Paul M

    2011-07-01

    The diagnosis of chronic Lyme disease has been embroiled in controversy for many years. This is exacerbated by the lack of a clinical or microbiologic definition, and the commonality of chronic symptoms in the general population. An accumulating body of evidence suggests that Lyme disease is the appropriate diagnosis for only a minority of patients in whom it is suspected. In prospective studies of Lyme disease, very few patients go on to have a chronic syndrome dominated by subjective complaints. There is no systematic evidence that Borrelia burgdorferi, the etiology of Lyme disease, can be identified in patients with chronic symptoms following treated Lyme disease. Multiple prospective trials have revealed that prolonged courses of antibiotics neither prevent nor alleviate such post-Lyme syndromes. Extended courses of intravenous antibiotics have resulted in severe adverse events, which in light of their lack of efficacy, make them contraindicated.

    Full Text Available BACKGROUND: It has been reported that the prevalence of chronic diseases is high among old people and they have poor chronic diseases knowledge. This study was therefore designed to evaluate the awareness rate of chronic diseases knowledge among people aged over 60 years, to explore its related factors and to provide evidence for future health education. METHODS: A cross-sectional study was conducted from April to August in 2011. People aged 60 years and above from 3 communities in Jinan were selected by cluster sampling. Nine hundred and twenty five participants were interviewed face-to-face using a structured questionnaire. RESULTS: The awareness rates of chronic diseases knowledge varied from 29.5% to 90.2%. Four healthy lifestyles including quitting smoking and less drinking, keeping broad-minded, maintaining balanced diet and moderate physical activity were best known (from 86.3% to 90.2%. The least known knowledge were 2 complications of hypertension: nephropathy (29.5% and retinopathy (37.2%. Participants with the following characteristics or behaviors were more likely to have higher chronic diseases knowledge: younger age, female, Han Chinese, higher level of education, having health insurance, participating in societies, having family history of chronic diseases, frequently gathering with friends/relatives, usually going to provincial hospitals/hospitals affiliated with medical universities, usually going to municipal hospitals and usually going to community health center/station. CONCLUSIONS: Old people in Jinan had incomplete chronic diseases knowledge and the overall awareness rate was not high. The older people's chronic diseases knowledge should be improved and health education programs should target males, older people with lower educational level, having no health insurance, having no family history of chronic diseases, participating in no societies, and less frequently gathering with friends/relatives. Also, lower level medical

    As Chronic Kidney Disease progresses slowly, early detection and effective treatment are the only cure to reduce the mortality rate. Machine learning techniques are gaining significance in medical diagnosis because of their classification ability with high accuracy rates. The accuracy of classification algorithms depend on the use of correct feature selection algorithms to reduce the dimension of datasets. In this study, Support Vector Machine classification algorithm was used to diagnose Chronic Kidney Disease. To diagnose the Chronic Kidney Disease, two essential types of feature selection methods namely, wrapper and filter approaches were chosen to reduce the dimension of Chronic Kidney Disease dataset. In wrapper approach, classifier subset evaluator with greedy stepwise search engine and wrapper subset evaluator with the Best First search engine were used. In filter approach, correlation feature selection subset evaluator with greedy stepwise search engine and filtered subset evaluator with the Best First search engine were used. The results showed that the Support Vector Machine classifier by using filtered subset evaluator with the Best First search engine feature selection method has higher accuracy rate (98.5%) in the diagnosis of Chronic Kidney Disease compared to other selected methods.

    In the context of the emerging field of public health services and systems research, this study (i) tested a model of the relationships between public health organizational capacity (OC) for chronic disease prevention, its determinants (organizational supports for evaluation, partnership effectiveness) and one possible outcome of OC (involvement in core chronic disease prevention practices) and (ii) examined differences in the nature of these relationships among organizations operating in more and less facilitating external environments. OC was conceptualized as skills and resources/supports for chronic disease prevention programming. Data were from a census of 210 Canadian public health organizations with mandates for chronic disease prevention. The hypothesized relationships were tested using structural equation modeling. Overall, the results supported the model. Organizational supports for evaluation accounted for 33% of the variance in skills. Skills and resources/supports were directly and strongly related to involvement. Organizations operating within facilitating external contexts for chronic disease prevention had more effective partnerships, more resources/supports, stronger skills and greater involvement in core chronic disease prevention practices. Results also suggested that organizations functioning in less facilitating environments may not benefit as expected from partnerships. Empirical testing of this conceptual model helps develop a better understanding of public health OC.

  10. Enteral nutrition in the chronic obstructive pulmonary disease (COPD) patient.

    DeBellis, Heather F; Fetterman, James W

    2012-12-01

    Chronic obstructive pulmonary disease (COPD) is a progressive, chronic disease, in which malnutrition can have an undesirable effect. Therefore, the patient's nutritional status is critical for optimizing outcomes in COPD. The initial nutrition assessment is focused on identifying calorically compromised COPD patients in order to provide them with appropriate nutrition. Nutritional intervention consists of oral supplementation and enteral nutrition to prevent weight loss and muscle mass depletion. Evaluation of nutritional status should include past medical history (medications, lung function, and exercise tolerance) and dietary history (patient's dietary habits, food choices, meal patterns, food allergy information, and malabsorption issues), in addition to physiological stress, visceral proteins, weight, fat-free mass, and body mass index. The current medical literature conflicts regarding the appropriate type of formulation to select for nutritional intervention, especially regarding the amount of calories from fat to provide COPD patients. This review article focuses on the enteral product formulations currently available, and how they are most appropriately utilized in patients with COPD.

    2014-02-01

    Chronic disease management (CDM) service models are being developed for many conditions; however, there is limited evidence to support their effectiveness in osteoarthritis (OA). A systematic review was undertaken to examine effectiveness, cost effectiveness and barriers to the use of osteoarthritis-chronic disease management (OA-CDM) service models. Thirteen eligible studies (eight randomised controlled trial (RCTs)) were identified. The majority focussed on delivery system design (n = 9) and/or providing self-management support (SMS) (n = 8). Overall, reported model effectiveness varied, and where positive impacts on process or health outcomes were observed, they were of small to moderate effect. There was no information about cost effectiveness. There is some evidence to support the use of collaborative care/multidisciplinary case management models in primary and community care and evidence-based pathways/standardisation of care in hospital settings. Multiple barriers were identified. Future research should focus on identifying the effective components of multi-faceted interventions and evaluating cost-effectiveness to support clinical and policy decision-making.

    Full Text Available Background: Chronic diseases are highly prevalent among men in the United States and chronic disease management is problematic for men, particularly for racial and ethnic minority men. Objectives: This study examined the association between health information seeking and confidence to manage chronic diseases among men. Methods: Study data were drawn from the 2007 Health Tracking Household Survey and analyzed using multiple binary logistic regressions. The analytical sample included 2,653 men, 18 years and older with a chronic illness. Results: Health information seeking was not associated with confidence to manage chronic illnesses. African-American men had lower odds than White men to agree to take actions to prevent symptoms with their health. Hispanic men had lower odds than White men to agree to tell a doctor concerns they have, even when not asked. Conclusions: Racial and ethnic minority men with a chronic condition appear to be less confident to manage their health compared to white men. Chronic disease management needs greater exploration to understand the best ways to help racial and ethnic minority men successfully manage their chronic condition.

    The rapidly growing body of research regarding the use of meditation interventions in chronic disease presents an opportunity to compare outcomes based on intervention content. For this review, meditation interventions were described as those interventions delivered to persons with chronic disease where sitting meditation was the main or only content of the intervention with or without the addition of mindful movement. This systematic review identified 45 individual research studies that examined meditations effect on levels of anxiety, depression, and chronic disease symptoms in persons with chronic disease. Individual studies were assessed based on interventional content, the consistency with which interventions were applied, and the research quality. This study identified seven categories of meditation interventions based on the meditation skills and mindful movement practices that were included in the intervention. Overall, half of the interventions had clearly defined and specific meditation interventions (25/45) and half of the studies were conducted using randomized control trials (24/45).

    The current volume and expected increases in the number of patients with chronic diseases are concerned significant and substantial. Patients with chronic diseases have a great need to personally manage their health-related behaviour, such as food consumption, and its impact on their health indicators, like blood pressure, body weight, blood sugar, cholesterol, to name a few. Current healthcare systems are unable to meet the needs of patients with chronic diseases for management, due to the need for acute care. An analysis of the needs was performed and recommendations for virtual communities were made to help patients with chronic diseases monitor and manage their health. Virtual communities have the potential to meet the need to assist with monitoring activities, education, community membership, and the sale of products and services. However, they also face risks inherent to accepting and storing any form of personal health information, and of remaining in compliance with the Health Insurance Portability and Accessibility Act of 2001.

    Full Text Available Phenols are uremic toxins of intestinal origin formed by bacteria during protein metabolism. Of these molecules, p-cresol is the most studied and has been associated with renal function impairment and vascular damage. Bisphenol A (BPA is a molecule with structural similarity with phenols found in plastic food and beverage containers as well as in some dialyzers. BPA is considered an environmental toxicant based on animal and cell culture studies. Japanese authorities recently banned BPA use in baby bottles based on observational association studies in newborns. BPA is excreted in urine and uremic patients present higher serum levels, but there is insufficient evidence to set cut-off levels or to link BPA to any harmful effect in CKD. However, the renal elimination and potential exposure during dialysis warrant the monitoring of BPA exposure and the design of observational studies in which the potential health risks of BPA for end-stage renal disease patients are evaluated.

    With high mortality and readmission rates among patients with heart failure (HF), multiple disease management models have been and continue to be tested, with mixed results. Early postdischarge care improves outcomes for patients. Telemonitoring also can assist in reducing mortality and HF-related hospitalizations. Office-based team care improves patient outcomes, with important components including rapid access to physicians, partnerships with clinical pharmacists, education, monitoring, and support. Pay-for-performance measures developed for HF, primarily use of angiotensin-converting enzyme inhibitors and beta blockers, also improve patient outcomes, but the influence of adherence to other measures has been minimal. Evaluating comorbid conditions, including diabetes and hypertension, and making drug adjustments for patients with HF to include blood pressure control and use of metformin, when possible, can reduce mortality and morbidity.

    Phenols are uremic toxins of intestinal origin formed by bacteria during protein metabolism. Of these molecules, p-cresol is the most studied and has been associated with renal function impairment and vascular damage. Bisphenol A (BPA) is a molecule with structural similarity with phenols found in plastic food and beverage containers as well as in some dialyzers. BPA is considered an environmental toxicant based on animal and cell culture studies. Japanese authorities recently banned BPA use in baby bottles based on observational association studies in newborns. BPA is excreted in urine and uremic patients present higher serum levels, but there is insufficient evidence to set cut-off levels or to link BPA to any harmful effect in CKD. However, the renal elimination and potential exposure during dialysis warrant the monitoring of BPA exposure and the design of observational studies in which the potential health risks of BPA for end-stage renal disease patients are evaluated.

    Full Text Available OBJECTIVE: Recent work has suggested that within-breath respiratory impedance measurements performed using the forced oscillation technique may help to noninvasively evaluate respiratory mechanics. We investigated the influence of airway obstruction on the within-breath forced oscillation technique in smokers and chronic obstructive pulmonary disease patients and evaluated the contribution of this analysis to the diagnosis of chronic obstructive pulmonary disease. METHODS: Twenty healthy individuals and 20 smokers were assessed. The study also included 74 patients with stable chronic obstructive pulmonary disease. We evaluated the mean respiratory impedance (Zm as well as values for the inspiration (Zi and expiration cycles (Ze at the beginning of inspiration (Zbi and expiration (Zbe, respectively. The peak-to-peak impedance (Zpp=Zbe-Zbi and the respiratory cycle dependence (ΔZrs=Ze-Zi were also analyzed. The diagnostic utility was evaluated by investigating the sensitivity, the specificity and the area under the receiver operating characteristic curve. ClinicalTrials.gov: NCT01888705. RESULTS: Airway obstruction increased the within-breath respiratory impedance parameters that were significantly correlated with the spirometric indices of airway obstruction (R=−0.65, p90%. CONCLUSIONS: We conclude the following: (1 chronic obstructive pulmonary disease introduces higher respiratory cycle dependence, (2 this increase is proportional to airway obstruction, and (3 the within-breath forced oscillation technique may provide novel parameters that facilitate the diagnosis of respiratory abnormalities in chronic obstructive pulmonary disease.

  10. Chronic Kidney Disease: Highlights for the General Pediatrician

    2012-01-01

    Full Text Available Chronic kidney disease in the pediatric population has been increasing. Early detection and treatment can slow down the progression of kidney disease and help prevent the development of end stage renal disease. In addition, as the kidney function declines, there are many pathophysiologic interactions with other organ systems that need to be monitored and treated. In particular, because of impaired vitamin D metabolism, calcium and phosphorus homeostasis is dysregulated and results in secondary bone disease. Anemia is common due to a number of factors including impaired erythropoietin production. Growth is often impacted by chronic kidney disease but can be improved by proper treatment. Complications of chronic kidney disease can be minimized by proper monitoring and treatment of these parameters. The general pediatrician plays a critical role in this process.

    The development of liver cirrhosis and portal hypertension (PH), one of its major complications, are structural and functional alterations of the liver, occurring in many patients with chronic liver diseases (CLD). Actually the progressive deposition of hepatic fibrosis has a key role in the prognosis of CLD patients. The subsequent development of PH leads to its major complications, such as ascites, hepatic encephalopathy, variceal bleeding and decompensation. Liver biopsy is still considered the reference standard for the assessment of hepatic fibrosis, whereas the measurement of hepatic vein pressure gradient is the standard to ascertain the presence of PH and upper endoscopy is the method of choice to detect the presence of oesophageal varices. However, several non-invasive tests, including elastographic techniques, are currently used to evaluate the severity of liver disease and predict its prognosis. More recently, the measurement of the spleen stiffness has become particularly attractive to assess, considering the relevant role accomplished by the spleen in splanchnic circulation in the course of liver cirrhosis and in the PH. Moreover, spleen stiffness as compared with liver stiffness better represents the dynamic changes occurring in the advanced stages of cirrhosis and shows higher diagnostic performance in detecting esophageal varices. The aim of this review is to provide an exhaustive overview of the actual role of spleen stiffness measurement as assessed by several elastographic techniques in evaluating both liver disease severity and the development of cirrhosis complications, such as PH and to highlight its potential and possible limitations.

    The rising global burden of chronic renal disease, the high cost of providing renal replacement therapies, and renal disease also being a risk factor for cardiovascular disease is increasing focus on renal disease prevention. This article focuses on the aspects of renal disease (specifically poststreptococcal glomerulonephritis [PSGN] and chronic kidney disease [CKD]) in Indigenous populations in Australia, New Zealand, Canada, and the United States that diverge from those typically seen in the general population of those countries. The spectrum of renal and many other diseases seen in Indigenous people in developed countries is similar to that seen in developing countries. Diseases like PSGN that have largely disappeared in developed countries still occur frequently in Indigenous people. CKD during the childhood years is due to congenital anomalies of the kidney and urinary tract in up to 70% of cases and occurs later in polycystic kidney disease and childhood-onset diabetes. Several risk factors for CKD in adulthood are already present in childhood.

    The relationship between patients and clinicians is a key element in the management of chronic diseases. With the objective of a more efficient communication, the clinician should know his own personality but also the patient personality. The organisation of the consultation, of the waiting room and of the secretary has to facilitate this relationship. The amelioration of this relationship is usefulness only for the clinician in particularly complicated cases but also for the patients suffering from chronic diseases.

    Along with the wide use of pesticides in the world, the concerns over their health impacts are rapidly growing. There is a huge body of evidence on the relation between exposure to pesticides and elevated rate of chronic diseases such as different types of cancers, diabetes, neurodegenerative disorders like Parkinson, Alzheimer, and amyotrophic lateral sclerosis (ALS), birth defects, and reproductive disorders. There is also circumstantial evidence on the association of exposure to pesticides with some other chronic diseases like respiratory problems, particularly asthma and chronic obstructive pulmonary disease (COPD), cardiovascular disease such as atherosclerosis and coronary artery disease, chronic nephropathies, autoimmune diseases like systemic lupus erythematous and rheumatoid arthritis, chronic fatigue syndrome, and aging. The common feature of chronic disorders is a disturbance in cellular homeostasis, which can be induced via pesticides' primary action like perturbation of ion channels, enzymes, receptors, etc., or can as well be mediated via pathways other than the main mechanism. In this review, we present the highlighted evidence on the association of pesticide's exposure with the incidence of chronic diseases and introduce genetic damages, epigenetic modifications, endocrine disruption, mitochondrial dysfunction, oxidative stress, endoplasmic reticulum stress and unfolded protein response (UPR), impairment of ubiquitin proteasome system, and defective autophagy as the effective mechanisms of action. - Highlights: ► There is a link between exposure to pesticides and incidence of chronic diseases. ► Genotoxicity and proteotoxicity are two main involved mechanisms. ► Epigenetic knowledge may help diagnose the relationships. ► Efficient policies on safe use of pesticides should be set up.

    Host-parasite dynamics and strategies for managing infectious diseases of wildlife depend on the functional relationship between disease transmission rates and host density. However, the disease transmission function is rarely known for free-living wildlife, leading to uncertainty regarding the impacts of diseases on host populations and effective control actions. We evaluated the influence of deer density, landscape features, and soil clay content on transmission of chronic wasting disease (CWD) in young (disease prevalence and density of infected deer, performed better than simple density- and frequency-dependent models. Our results indicate a combination of social structure, non-linear relationships between infectious contact and deer density, and distribution of disease among groups are important factors driving CWD infection in young deer. The landscape covariates % deciduous forest cover and forest edge density also were positively associated with infection rates, but soil clay content had no measurable influences on CWD transmission. Lack of strong density-dependent transmission rates indicates that controlling CWD by reducing deer density will be difficult. The consequences of non-linear disease transmission and aggregation of disease on cervid populations deserves further consideration.

  19. Health Status Measurement Instruments in Chronic Obstructive Pulmonary Disease

    Full Text Available Chronic obstructive pulmonary disease (COPD is associated with primary respiratory impairment, disability and handicap, as well as with secondary impairments not necessarily confined to the respiratory system. Because the primary goals of managing patients with COPD include relief of dyspnea and the improvement of health-related quality of life (HRQL, a direct measurement of HRQL is important. Fourteen disease-specific and nine generic questionnaires (four health profiles and five utility measures most commonly used to measure health status in patients with COPD were reviewed. The measures were classified according to their domain of interest, and their measurement properties - specifications, validity, reliability, responsiveness and interpretability - were described. This review suggests several findings. Currently used health status instruments usually refer to the patients’ perception of performance in three major domains of HRQL - somatic sensation, physical and occupational function, and psychological state. The choice of a questionnaire must be related to its purpose, with a clear distinction being made between its evaluative and discriminative function. In their evaluative function, only a few instruments fulfilled the criteria of responsiveness, and the interpretability of most questionnaires is limited. Generic questionnaires should not be used alone in clinical trials as evaluative instruments because of their inability to detect change over time. Further validation and improved interpretability of existing instruments would be of greater benefit to clinicians and scientists than the development of new questionnaires.

    Full Text Available Objective: to study the specific features of development of cognitive impairments (CIs, the role of traditional cardiovascular risk factors and renal failure-induced factors in patients with Stages I–IV chronic kidney disease (CKD and to assess an association of CIs with the signs of vascular wall remodeling in them. Patients and methods. Fifty-one patients aged 53±10 years with CKD were examined. Among them, there were 20 patients with Stages I–II CKD: a glomerular filtration rate (GFR of і60 ml/min/1.73 m2, signs of renal lesion; 20 with Stages III CKD: a GFR of <60–30 ml/min/1.73 m2, and 11 with Stages VI CKD: a GFR of <30–15 ml/min/1.73 m2. Results and discussion. CIs were more common in the patients with Stages III–IV than in those with Stages I–II, as shown by the scores of the mini-mental state examination (p<0.001, the frontal assessment battery (p=0.001, and the regulatory function test (p<0.001. These tests showed that the magnitude of CIs increased with the higher stage of CKD. Stages III–IV CKD is an independent predictor of CIs in persons with predialysis-stage kidney lesion. CIs were found to be related to hyperhomocysteinemia, anemia, abdominal obesity, left ventricular hypertrophy, and patient age. The signs of atherosclerotic lesion of the common carotid arteries and the indicators of arterial stiffness were also associated with the incidence and magnitude of CIs in CKD. The detection of CIs in patients with early CKD allows one to timely initiate adequate therapy aimed particularly at improving cerebral circulation, eliminating the impact of risk factors, and slowing down the vascular remodeling. The management tactics for patients with CKD must involve the identification and correction of cardiovascular risk factors, and duplex scanning of the wall of the common carotid arteries may be used as a noninvasive method to assess the risk of the development and progression of CIs in predialysis CKD.

    Anaemia is a condition in which the number of red cells necessary to meet the body's physiological requirements is insufficient. Iron deficiency anaemia and the anaemia of chronic disease are the two most common causes of anaemia worldwide;(1) iron homeostasis plays a pivotal role in the pathogenesis of both diseases. An understanding of how iron studies can be used to distinguish between these diseases is therefore essential not only for diagnosis but also in guiding management. This review will primarily focus on iron deficiency anaemia and anaemia of chronic disease; however, iron overload in anaemia will also be briefly discussed.

    Chronic kidney disease affects millions of people worldwide and is associated with an increased morbidity and mortality as a result of kidney failure and cardiovascular disease. Accurate assessment of kidney function is important in the clinical setting as a screening tool and for monitoring disease progression and guiding prognosis. In clinical research, the development of new methods to measure kidney function accurately is important in the search for new therapeutic targets and the discovery of novel biomarkers to aid early identification of kidney injury. This review considers different methods for measuring kidney function and their contribution to the improvement of detection, monitoring and treatment of chronic kidney disease.

    Full Text Available The Kidney Disease: Improving Global Outcomes (KDIGO work group released recommendations in 2006 to define the bone-related pathology associated with chronic kidney disease as renal osteodystrophy. In 2009, KDIGO released revised clinical practice guidelines which redefined systemic disorders of bone and mineral metabolism due to chronic kidney disease as chronic kidney disease-mineral and bone disorders. Conditions under this overarching term include osteitis fibrosa cystica, osteomalacia, and adynamic bone disease. We aim to provide a brief review of the histopathology, pathophysiology, epidemiology, and diagnostic features of adynamic bone disease, focusing on current trends in the management of this complex bone disorder.

    This work compared the time at which negative seroconversion was detected by conventional serology (CS) and by the ELISA-F29 test on a cohort of chronic chagasic patients treated with nifurtimox or benznidazole. A retrospective study was performed using preserved serum from 66 asymptomatic chagasic adults under clinical supervision, and bi-annual serological examinations over a mean follow-up of 23 years. Twenty nine patients received trypanocide treatment and 37 remained untreated. The ELISA-F29 test used a recombinant antigen which was obtained by expressing the Trypanosoma cruzi flagellar calcium-binding protein gene in Escherichia coli. Among the untreated patients, 36 maintained CS titers. One patient showed a doubtful serology in some check-ups. ELISA-F29 showed constant reactivity in 35 out of 37 patients and was negative for the patient with fluctuating CS. The treated patients were divided into three groups according to the CS titers: in 13 they became negative; in 12 they decreased and in four they remained unchanged. ELISA-F29 was negative for the first two groups. The time at which negativization was detected was significantly lower for the ELISA-F29 test than for CS, 14.5 ± 5.7 and 22 ± 4.9 years respectively. Negative seroconversion was observed in treated patients only. The results obtained confirm that the ELISA-F29 test is useful as an early indicator of negative seroconversion in treated chronic patients.

    2016-01-01

    Chronic fatigue--an overwhelming subjective feeling of mental or physical exhaustion--impacts patients' everyday functioning and quality of life, delays recovery after hemodialysis, and increases mortality. There are a number of factors that may perpetuate clinically significant fatigue among individuals with chronic kidney disease, including sleep disorders, depression, sedentary lifestyle, anemia, and chronic inflammation. Some of these factors (i.e., anemia and inflammation) are in the forefront of clinical attention, whereas the other contributing factors often remain unrecognized. This article provides a pragmatic overview of the definition, assessment, maintaining factors, and management of fatigue in chronic kidney disease. Given that chronic fatigue is a major determinant of patients' quality of life, nurses can bring about a fundamental improvement in patients' well-being if they recognize the most common fatigue-perpetuating factors and facilitate fatigue management interventions.

    There is no better example of a relentless attack on evidence-based biomedical research and the integrity of outstanding scientists than that associated with the treatment of a poorly defined condition called "chronic Lyme disease." Here, a scientifically naive general population, the lay press, and legislators, who in most instances are unable to evaluate and judge scientific evidence properly, have been misled by patient advocate groups to believe that extended antibiotic therapy is the best and only solution to this condition. This has resulted in the unprecedented intrusion of government and the legal systems into the practice of medicine and scientific research. Because there is no clinical evidence that this condition is due to a persistent infection, advocating extended antibiotic therapy is not justified and has been shown to be harmful and of no benefit.

    A high degree of uncertainty exists for chronic wasting disease (CWD) transmission factors in farmed and wild cervids. Evaluating the factors is important as it helps to inform future risk management strategies. Expert opinion is often used to assist decision making in a number of health, science, and technology domains where data may be sparse or missing. Using the "Classical Model" of elicitation, a group of experts was asked to estimate the most likely values for several risk factors affecting CWD transmission. The formalized expert elicitation helped structure the issues and hence provide a rational basis for estimating some transmission risk factors for which evidence is lacking. Considered judgments regarding environmental transmission, latency of CWD transmission, management, and species barrier were provided by the experts. Uncertainties for many items were determined to be large, highlighting areas requiring more research. The elicited values may be used as surrogate values until research evidence becomes available.

    Portilla Franco, Maria Eugenia; Tornero Molina, Fernando; Gil Gregorio, Pedro

    In recent years, the concept of frailty as a "state of pre-disability" has been widely accepted by those involved in the care of the elderly. Its importance lies not only in its high prevalence - more than 25% in people over 85 years of age - but it is also considered an independent risk factor of disability, institutionalisation and mortality amongst the elderly. The study of renal function is relevant in patients with major comorbidities. Studies have shown a significant association between chronic kidney disease and the development of adverse clinical outcomes such as heart disease, heart failure, end-stage renal disease, increased susceptibility to infections and greater functional impairment. Frailty can be reversed, which is why a study of frailty in patients with chronic kidney disease is of particular interest. This article aims to describe the association between ageing, frailty and chronic kidney disease in light of the most recent and relevant scientific publications.

    Full Text Available An exploratory and descriptive study with a qualitative approach aim at understanding the significance of the discovery of chronic kidney disease and the need for the hemodialysis machine. The research was made with twenty patients from two hemodialysis services of the city of RS. The data collection took place between September and December of 2007, throughout semi-structured interviews. The thematic analysis generated the following categories: history of chronic kidney disease, from the silence of the disease to the classical clinical symptoms; the discovery and its immediate effects; life after the discovery; acceptance of the dependence on a machine. We conclude that there is a need to adapt the daily life of patients with chronic kidney disease, because the hemodialysis causes physical and social changes, requiring support from health-team to manage the disease. The professional should not abdicate knowledge, safety and technical skill, as requirements to care.

    Risk analysis tools have been successfully used to determine the potential hazard associated with disease introductions and have facilitated management decisions designed to limit the potential for disease introduction. Chronic Wasting Disease (CWD) poses significant challenges for resource managers due to an incomplete understanding of disease etiology and epidemiology and the complexity of management and political jurisdictions. Tools designed specifically to assess the risk of CWD introduction would be of great value to policy makers in areas where CWD has not been detected.

Most patients with COPD rely on primary care practices for COPD management. Unfortunately, only about 55% of US outpatients with COPD receive all guideline-recommended care. Proactive and consistent primary care for COPD, as for many other chronic diseases, can reduce hospitalizations. Optimal chronic disease management requires focusing on maintenance rather than merely acute rescue. The Patient-Centered Medical Home (PCMH, which implements the chronic care model, is a promising framework for primary care transformation. This review presents core PCMH concepts and proposes multidisciplinary team-based PCMH care strategies for COPD.Keywords: Patient-Centered Medical Home, chronic care model, chronic obstructive pulmonary disease, patient education, physician assistants, nurse practitioners

    Background Chronic inflammatory diseases (CID) are globally highly prevalent and characterized by severe pathological medical conditions. Several trials were conducted aiming at measuring the effects of manipulative therapies on patients affected by CID. The purpose of this review was to explore the extent to which osteopathic manipulative treatment (OMT) can be benefi-cial in medical conditions also classified as CID. Methods This review included any type of experimental study which enrolled sub-jects with CID comparing OMT with any type of control procedure. The search was conducted on eight databases in January 2014 using a pragmatic literature search approach. Two independent re-viewers conducted study selection and data extraction for each study. The risk of bias was evaluated according to the Cochrane methods. Heterogeneity was assessed and meta-analysis performed where possible. Results 10 studies met the inclusion criteria for this review enrolling 386 subjects. The search identified six RCTs, one laboratory study, one cross-over pilot studies, one observation-al study and one case control pilot study. Results suggest a potential effect of osteopathic medicine on patients with medical pathologies associated with CID (in particular Chronic Obstructive Pul-monary Disease (COPD), Irritable Bowel Syndrome, Asthma and Peripheral Arterial Disease) com-pared to no treatment or sham therapy although data remain elusive. Moreover one study showed possible effects on arthritis rat model. Meta-analysis was performed for COPD studies only show-ing no effect of any type of OMT applied versus control. No major side effects were reported by those receiving OMT.

Further more robust trials are needed to determine the direction and magnitude of the effect of OMT and to generalize favorable results.

Nevertheless, falls are associated to increased mortality, decreased independence and physical activity levels, and worsening of quality of life. The aims of this systematic review was to evaluate information in the literature with regard to whether impaired postural control is more prevalent in COPD patients than in healthy age-matched subjects, and to assess the main characteristics these patients present that contribute to impaired postural control.Methods: Five databases were searched with no dates or language limits. The MEDLINE, PubMed, EMBASE, Web of Science, and PEDro databases were searched using “balance”, “postural control”, and “COPD” as keywords. The search strategies were oriented and guided by a health science librarian and were performed on March 27, 2014. The studies included were those that evaluated postural control in COPD patients as their main outcome and scored more than five points on the PEDro scale. Studies supplied by the database search strategy were assessed independently by two blinded researchers.Results: A total of 484 manuscripts were found using the “balance in COPD or postural control in COPD” keywords. Forty-three manuscripts appeared more than once, and 397 did not evaluate postural control in COPD patients as the primary outcome. Thus, only 14 studies had postural control as their primary outcome. Our study

Halotherapy is the inhalation of micronized dry salt within a chamber that mimics a salt cave environment. Recent media reports suggest that this therapy may help with the symptoms of COPD. Objective: To critically evaluate and summarize the evidence for the use of halotherapy as a treatment for COPD. Design: A review using systematic approach and narrative synthesis. Data sources: Cochrane Central Register of Controlled Trials (CENTRAL, PubMed, MEDLINE, EMBASE, CINAHL, and Google Scholar were searched. Two reviewers independently reviewed abstracts and selected eligible studies based on predetermined selection criteria. Results: Of the 151 articles retrieved from databases and relevant reference lists, only one randomized controlled trial met the inclusion criteria. A meta-analysis was unable to be conducted due to the limited number of published studies. Inclusion criteria were subsequently expanded to allow three case-control studies to be included, ensuring that a narrative synthesis could be completed. From the pooled data of the four studies, there were 1,041 participants (661 in the intervention group and 380 in the control group. The assessment of methodological quality raised issues associated with randomization and patient selection

    2016-02-01

    Acute asthma and chronic obstructive pulmonary disease (COPD) exacerbations are the most common respiratory diseases requiring emergent medical evaluation and treatment. Asthma and COPD are chronic, debilitating disease processes that have been differentiated traditionally by the presence or absence of reversible airflow obstruction. Asthma and COPD exacerbations impose an enormous economic burden on the US health care budget. In daily clinical practice, it is difficult to differentiate these 2 obstructive processes based on their symptoms, and on their nearly identical acute treatment strategies; major differences are important when discussing anatomic sites involved, long-term prognosis, and the nature of inflammatory markers.

    Cardiovascular disease is the leading cause of death in patients who have chronic kidney disease or end-stage renal disease and are undergoing hemodialysis. Chronic kidney disease is a recognized risk factor for premature atherosclerosis. Unfortunately, most major randomized clinical trials that form the basis for evidence-based use of revascularization procedures exclude patients who have renal insufficiency. Retrospective, observational studies suggest that patients with end-stage renal disease and severe coronary occlusive disease have a lower risk of death if they undergo coronary revascularization rather than medical therapy alone. Due to a lack of prospective studies, however, the relative merits of percutaneous versus surgical revascularization are merely a matter of opinion. Several small, retrospective studies have shown that coronary artery bypass grafting is associated with higher procedural death but better long-term survival than is percutaneous coronary intervention. This difference appears to result from poor long-term results of percutaneous coronary intervention in patients who have chronic kidney disease or end-stage renal disease.Because randomized trials comparing percutaneous coronary intervention and coronary artery bypass grafting have included patients undergoing balloon angioplasty and placement of bare-metal stents, their conclusions are suspect in the era of drug-eluting stents. In this review, we discuss different revascularization options for patients with chronic kidney disease, the outcomes of revascularization procedures, and the risk factors for adverse outcomes.

    Chronic inflammation of the larger airways is a common occurrence in children. A number of factors such as younger age, premature birth, male gender, exposure to environmental smoke or pollution, and crowded housing can increase a child's susceptibility to chronic lung disease. Chronic bronchitis may be caused by an underlying humoral immunodeficiency if the clinical course is recurrent or prolonged. Primary humoral immunodeficiency accounts for approximately 70% of all immunodeficiencies. The differential of chronic bronchitis also includes Cystic Fibrosis, ciliary defects and immune cellular and phagocytic defects. This review will summarize the most common humoral antibody based immune based deficiencies associated with chronic pulmonary disease.

    Objective:To evaluate hearing threshold and the severity of hearing loss at different frequencies in patients with chronic renal failure (CRF), and to analyze the role of duration of disease on hearing threshold in patients of CRF by measuring pure-tone audiometry (PTA) and distortion-product otoacoustic emission (DPOAE). Methods: There were analysed 61 subjects (122 ears) from which 12 were patients starting hemodialise (A), 24 subjects were patients undergoing hemodialise over a year (B), 15 subjects were patients undergoing conservative treatment (C) and 10 controls (D). We did hearing evaluation by testing them using tympanometry, PTA and DPOAEs. Other parameters (blood pressure, body weight, blood chemistries) were also evaluated. Results:It was found a severe high-frequency hearing loss among patients with CRF comparing to the control group. Duration on haemodialysis treatment does not seem to have a significant impact on the incidence of hearing loss, although the method of treatment may influence the impact of the disease on hearing. Hearing loss among patients with CRF seemed to deteriorate further a year after the first evaluation. Conclusions:DPOAE raised the percentages of detection of SNHL indicating that it is a better technique than the conventional PTA for evaluation of hearing acuity.

    Full Text Available BACKGROUND: Patients with Chagas disease have migrated to cities, where obesity, hypertension and other cardiac risk factors are common. METHODOLOGY/PRINCIPAL FINDINGS: The study included adult patients evaluated by the cardiology service in a public hospital in Santa Cruz, Bolivia. Data included risk factors for T. cruzi infection, medical history, physical examination, electrocardiogram, echocardiogram, and contact 9 months after initial data collection to ascertain mortality. Serology and PCR for Trypanosoma cruzi were performed. Of 394 participants, 251 (64% had confirmed T. cruzi infection by serology. Among seropositive participants, 109 (43% had positive results by conventional PCR; of these, 89 (82% also had positive results by real time PCR. There was a high prevalence of hypertension (64% and overweight (body mass index [BMI] >25; 67%, with no difference by T. cruzi infection status. Nearly 60% of symptomatic congestive heart failure was attributed to Chagas cardiomyopathy; mortality was also higher for seropositive than seronegative patients (p = 0.05. In multivariable models, longer residence in an endemic province, residence in a rural area and poor housing conditions were associated with T. cruzi infection. Male sex, increasing age and poor housing were independent predictors of Chagas cardiomyopathy severity. Males and participants with BMI evaluated in the context of the epidemiological transition that has increased risk of obesity, hypertension and chronic cardiovascular disease.

    2015-01-01

    The objective of this research is to evaluate empirically the effectiveness of eHealth in Nishi-aizu Town, Fukushima Prefecture, based on a mail survey to the residents and their receipt data of National Health Insurance from November 2006 to February 2007. The residents were divided into two groups, users and non-users, and sent questionnaires to ask their characteristics or usage of the system. Their medical expenditures paid by National Health Insurance for five years from 2002 to 2006 are examined. The effects were analyzed by comparison of medical expenditures between users and non-users. The interests are focused on four chronic diseases namely heart diseases, high blood pressure, diabetes, and strokes. A regression analysis is employed to estimate the effect of eHealth to users who have these diseases and then calculate the monetary effect of eHealth on reduction of medical expenditures. The results are expected to be valid for establishment of evidence-based policy such as reimbursement from medical insurance to eHealth.

    Rural-urban differences in the prevalence of chronic diseases in the adult population of northeast China are examined. The Jilin Provincial Chronic Disease Survey used personal interviews and physical measures to research the presence of a range of chronic diseases among a large sample of rural and urban provincial residents aged 18 to 79 years (N = 21 435). Logistic regression analyses were used. After adjusting for age and gender, rural residents had higher prevalence of hypertension, chronic ischemic heart disease, cerebrovascular disease, chronic low back pain, arthritis, chronic gastroenteritis/peptic ulcer, chronic cholecystitis/gallstones, and chronic lower respiratory disease. Low education, low income, and smoking increased the risk of chronic diseases in rural areas. Reducing rural-urban differences in chronic disease presents a formidable public health challenge for China. The solution requires focusing attention on issues endemic to rural areas such as poverty, lack of chronic disease knowledge, and the inequality in access to primary care.

    Adoption of health information technology (HIT) is a key effort in improving care delivery, reducing costs of health care, and improving the quality of health care. Evidence from electronic health record (EHR) use suggests that HIT will play a significant role in transforming primary care practices and chronic disease management. This article shows that EHRs and HIT can be used effectively to manage chronic diseases, that HIT can facilitate communication and reduce efforts related to transitions in care, and that HIT can improve patient safety by increasing the information available to providers and patients, improving disease management and safety.

    Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death in the United States with a burden of $50 billion in direct health care costs. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) defines airflow obstruction as spirometry where the ratio of forced expiratory volume in the first second to forced vital capacity after bronchodilation is less than 0.70. The guidelines also provided graded recommendations on current therapy for COPD. Treatment can be guided based on severity of disease and severity of symptoms. We review the GOLD guidelines to provide an overview of treatment modalities aimed at improving lung function, reducing hospitalization, and reducing mortality.

    Full Text Available Chronic diseases and their associated risk factors are increasing in India. We aim to quantify the Population Attributable Fractions (PAF of leading chronic diseases in India associated with significant modifiable risk factors. In calculating adjusted population attributable fraction, non modifiable risk factors are taken as confounders. Our findings highlight that an agenda to improve public health in India must include effective interventions to control tobacco use for cancer and heart disease prevention. There is also an urgent need to educate the general public to maintain proper BMI level thereby reducing diabetes burden in India. The analysis is based on a country wide large scale survey.

    Jani-Acsadi, Agnes; Lewis, Richard A

    2013-01-01

    Demyelinating neuropathies are typically characterized by physiological slowing of conduction velocity and pathologically by segmental loss of myelin and in some instances, evidence of remyelination. Clinically, patients with demyelinating neuropathy can be seen with inherited disorders (Charcot-Marie-Tooth disease) or acquired disorders, typically immune-mediated or inflammatory. The acquired disorders can be either acute or subacute as seen in the acute inflammatory demyelinating polyneuropathy (AIDP) form of Guillain-Barré syndrome or chronic progressive or relapsing disorders such as chronic inflammatory demyelinating polyneuropathy. It is important to develop a logical approach to diagnosing these disorders. This requires an understanding of the clinical, genetic, physiological, and pathological features of these neuropathies. Clinically, important features to consider are the temporal progression, degree of symmetry, and involvement of proximal as well as distal muscles. Genetically, recognizing the different inheritance patterns and age of onset allow for a coordinated approach to determining a specific genotype. Physiologically, besides nerve conduction slowing, other physiological hallmarks of demyelination include temporal dispersion of compound motor action potentials (CMAP) on proximal stimulation, conduction block, and distal CMAP duration prolongation with certain patterns of involvement pointing to specific disorders. This chapter focuses on these various aspects of the evaluation of patients with chronic acquired demyelinating neuropathies to develop a comprehensive and thoughtful diagnostic concept.

  13. Ageism as a Risk Factor for Chronic Disease.

    Allen, Julie Ober

    2016-08-01

    Ageism is one of the most socially condoned and institutionalized forms of prejudice in the United States. Older adults are discriminated against in employment, health care, and other domains. Exposure to unfavorable stereotypes adversely affects the attitudes, cognitions, and behavior of older adults. Recurrent experiences with negative stereotypes combined with discrimination may make ageism a chronic stressor in the lives of older adults. The way stress influences physical health is gaining increasing support. The weathering hypothesis (Geronimus, A. T. (1992) The weathering hypothesis and the health of African-American women and infants: Evidence and speculations. Ethnicity and Disease, 2, 207-221) posits that the cumulative effects of chronic objective and subjective stressors and high-effort coping cause deterioration of the body, premature aging, and associated health problems such as chronic diseases. Researchers have found empirical support for the weathering hypothesis as well as its theorized contribution to racial and ethnic health disparities. Although ageism is not experienced over the entire life course, as racism typically is, repeated exposure to chronic stressors associated with age stereotypes and discrimination may increase the risk of chronic disease, mortality, and other adverse health outcomes. I conclude with implications for practice in the helping professions and recommendations for future research. Ageism warrants greater recognition, social condemnation, and scientific study as a possible social determinant of chronic disease.

    Full Text Available Chronic kidney disease (CKD is a worldwide public health problem. Patients with CKD have a number of disorders in the organism, and the presence of oxidative stress and systemic inflammation in these patients is the subject of numerous studies. Chronic inflammation joined with oxidative stress contributes to the development of numerous complications: accelerated atherosclerosis process and cardiovascular disease, emergence of Type 2 diabetes mellitus, development of malnutrition, anaemia, hyperparathyroidism, and so forth, affecting the prognosis and quality of life of patients with CKD. In this review we presented the potential role of the myeloperoxidase enzyme in the production of reactive/chlorinating intermediates and their role in oxidative damage to biomolecules in the body of patients with chronic kidney disease and end-stage renal disease. In addition, we discussed the role of modified lipoprotein particles under the influence of prooxidant MPO intermediates in the development of endothelial changes and cardiovascular complications in renal failure.

    2016-01-01

    Chronic disease represents the epidemic of our time, present in half the adult population and responsible for 86% of United States (US) healthcare costs and 70% of deaths. The major chronic diseases are primarily due to health risk behaviors that are widely communicable across populations. As a nation, the US has performed poorly in managing chronic disease, in large part because of a failed delivery model of care. New opportunities exist as a result of recent advances in home-based wireless devices, apps and wearables, enabling health delivery systems to monitor disease metrics in near real time. These technologies provide a framework for patient engagement and a new model of care delivery utilizing integrated practice units, both of which are needed to navigate the healthcare needs of the 21st century.

    2015-04-01

    Alzheimer's disease, an affliction of old age, is one of the leading causes for dementia worldwide. Various risk factors including family history, genetics and infections have been implicated in its pathogenesis. The cognitive decline in this condition is mainly a result of the formation of amyloid deposits that provoke neuroinflammation, ultimately resulting in cell death. Recently, an association between peripheral inflammation and Alzheimer's disease was hypothesized. It was suggested that chronic systemic inflammation worsened the inflammatory processes in the brain. This was mainly attributed to increased levels of pro-inflammatory mediators, such as interleukin-1, interleukin -6 and tumor necrosis factor-α in the plasma. As chronic periodontitis is a widespread peripheral immunoinflammatory condition, it has been proposed to play a significant role in the aggravation of Alzheimer's disease. With this background, the current review focuses on the relationship between Alzheimer's disease and chronic periodontitis, and its therapeutic implications.

    Full Text Available Most of the diseases that the modern person faces in developed countries are chronic. These illnesses in their majority are not cured finally, but constitute situations that we try to control. The use of pharmaceutical medicines and the changes in the life of an individual allow henceforth in the chronically patients to live for along time duration an almost "physiologic" life, even if the chronic disease continues accompanying them. It is already known in all the interdisciplinary health care team that the chronically suffering patients present an enormous variety and differentiation of behaviours and experience abundance biological, psychological and social problems.This ascertainment led the researchers to develop a wide spectrum of theoretical approaches and clinical applications, with basic protractor of their efforts the maintenance of life’s quality as much patients who bear from chronic diseases as their familial environment.Aim of the present literature review was to investigate all the factors that interact in the psychology of an individual at the event of chronic disease, to report all the ways of adaptation in the new situation, and to assign all the nursing interventions that contribute positively in the acceptance of chronic illness.The education of patients with chronic diseases constitutes the corner stone of right therapeutic confrontation. The acceptance by the patient of changes that is required in his way of life is easier provided that when he has completely comprehended the nature of his illness, the gravity of his situation and role that plays the right collaboration with the health care providers.

    2014-01-01

    The increase in chronic diseases and the progressive ageing of the population is a source of concern for the different agencies with responsibility for health care. This has led to the creation of many documents focused on the analysis of the current situation and care of chronic diseases, including the WHO recommendations intended to assist countries and health services design and implement strategies that will address the existing demand, control and prevention of chronic diseases. In addition, there is a need to respond to the demand generated by chronic diseases in every sense, and from the different systems it is becoming more difficult to get enough support from multidisciplinary teams where the nurse has a central importance. While chronic diseases are becoming a threat due to the costs they generate, it is also an opportunity for nursing to be at the forefront for advanced care requirements, performed by professionals with recognized advanced clinical skills and ability for case management while monitoring and controlling complex chronic patients. The different services of the National Health System have introduced nurses that play different roles (cases managers, liaison nurses, advanced practice nurses and so on). However, it could be argued that they are not being trained to a desirable development level. It is therefore time for health care authorities to determine the role of the advanced practice nurse in relation to functional positions, and allow them to make an advance in the development of unified skills for the whole National Health System. From our experience we have learned that the advanced practice nurse is a resource that helps in the sustainability of services, thanks to the efficiency shown in the results obtained from the care given to both chronic and complex chronic patients.

    Exercise training is an effective way to improve exercise capacity in chronic kidney disease (CKD), but the underlying mechanisms are only partly understood. In healthy subjects (HS), microRNA (miRNA or miR) are dynamically regulated following exercise and have, therefore, been suggested as regulators of cardiovascular adaptation to exercise. However, these effects were not studied in CKD before. The effect of acute exercise (i.e., an acute exercise bout) was assessed in 32 patients with CKD and 12 age- and sex-matched HS (study 1). miRNA expression in response to chronic exercise (i.e., a 3-mo exercise training program) was evaluated in 40 CKD patients (study 2). In a subgroup of study 2, the acute-exercise induced effect was evaluated at baseline and at follow-up. Plasma levels of a preselected panel miRNA, involved in exercise adaptation processes such as angiogenesis (miR-126, miR-210), inflammation (miR-21, miR-146a), hypoxia/ischemia (miR-21, miR-210), and progenitor cells (miR-150), were quantified by RT-PCR. Additionally, seven miRNA involved in similar biological processes were quantified in the subgroup of study 2. Baseline, studied miRNA were comparable in CKD and HS. Following acute exercise, miR-150 levels increased in both CKD (fold change 2.12 ± 0.39, P = 0.002; and HS: fold change 2.41 ± 0.48 P = 0.018, P for interaction > 0.05). miR-146a acutely decreased in CKD (fold change 0.92 ± 0.13, P = 0.024), whereas it remained unchanged in HS. Levels of miR-21, miR-126, and miR-210 remained unaltered. Chronic exercise did not elicit a significant change in the studied miRNA levels. However, an acute exercise-induced decrease in miR-210 was observed in CKD patients, only after training (fold change 0.76 ± 0.15). The differential expression in circulating miRNA in response to acute and chronic exercise may point toward a physiological role in cardiovascular adaptation to exercise, also in CKD.

    2016-01-01

    The literature lacks reports on the role of the social relationships domain (SRD) of quality of life (QoL) in shaping care for patients with chronic respiratory diseases in primary care. In this study we examined a group of 582 patients with chronic respiratory diseases and chronic non-respiratory diseases recruited from 199 primary care centers. In the patients with chronic respiratory diseases, higher SRD correlated with more frequent patient visits due to medical issue, fewer district nurse interventions over the past 12 months, less frequent hospitalizations over the past 3 years, and fewer chronic diseases. In these patients, a high SRD was most effectively created by high QoL in the Psychological, Environmental, and Physical domains, and the satisfaction with QoL. Programs for preventing a decline in SRD should include patients with low scores in the Psychological, Environmental, and Physical domains, those who show no improvement in mental or somatic well-being in the past 12 months, those with a low level of positive mental attitudes, unhealthy eating habits, and with low levels of met needs. Such programs should include older widows and widowers without permanent relationships, with only primary education, living far from a primary care center, and those whose visits were not due to a medical issue.

  8. Asthma, chronic obstructive pulmonary disease (COPD), and the overlap syndrome.

    Science.gov (United States)

    Nakawah, Mohammad Obadah; Hawkins, Clare; Barbandi, Farouk

    2013-01-01

    Asthma and chronic obstructive pulmonary disease (COPD) are highly prevalent chronic diseases in the general population. Both are characterized by heterogeneous chronic airway inflammation and airway obstruction. In both conditions, chronic inflammation affects the whole respiratory tract, from central to peripheral airways, with different inflammatory cells recruited, different mediators produced, and thus differing responses to therapy. Airway obstruction is typically intermittent and reversible in asthma but is progressive and largely irreversible in COPD. However, there is a considerable pathologic and functional overlap between these 2 heterogeneous disorders, particularly among the elderly, who may have components of both diseases (asthma-COPD overlap syndrome). The definitions for asthma and COPD recommended by current guidelines are useful but limited because they do not illustrate the full spectrum of obstructive airway diseases that is encountered in clinical practice. Defining asthma and COPD as separate entities neglects a considerable proportion of patients with overlapping features and is largely based on expert opinion rather than on the best current evidence. The presence of different phenotypes or components of obstructive airway diseases, therefore, needs to be addressed to individualize and optimize treatment to achieve the best effect with the fewest side effects for the patient. Although specific interventions vary by disease, the treatment goals of obstructive airway diseases are similar and driven primarily by the need to control symptoms, optimize health status, and prevent exacerbations.

    Management of the pregnant woman with chronic kidney disease is difficult for both nephrologists and obstetricians. Prepregnancy counselling with respect to risk stratification, optimization of maternal health prior to pregnancy, as well as management of the many potential pregnancy-associated complications in this complex patient population remains challenging due to the paucity of large, well-designed clinical studies. Furthermore, the heterogeneity of disease and the relative infrequency of pregnancy, particularly in more advanced stages of chronic kidney disease, leaves many clinicians feeling ill prepared to manage these pregnancies. As such, counselling is imprecise and management varies substantially across centers. All pregnancies in women with chronic kidney disease can benefit from a collaborative multidisciplinary approach with a team that consists of nephrologists experienced in the management of kidney disease in pregnancy, maternal-fetal medicine specialists, high-risk pregnancy nursing staff, dieticians, and pharmacists. Further access to skilled neonatologists and neonatal intensive care unit support is essential given the risks for preterm delivery in this patient population. The goal of this paper is to highlight some of the data that currently exist in the literature, provide management strategies for the practicing nephrologist at all stages of chronic kidney disease, and explore some of the knowledge gaps where future multinational collaborative research efforts should concentrate to improve pregnancy outcomes in women with kidney disease across the globe.

    Full Text Available Background: The Chronic Inflammatory Periodontal Disease is related with multiple risk factors. Those patients with human immunodeficiency virus have higher risk of presenting this disease and it is usually more serious in these cases. Objective: To describe the prevalence of Chronic Inflammatory Periodontal Disease in patients with HIV. Methods: Descriptive, observational, cross-sectional study including patients with HIV in Sancti Spiritus province. The occurrence of the disease was determined after the Periodontics Cuban Standards, and oral hygiene was assessed through the simplified oral hygiene index. Other variables were measured, such as smoking habits, T CD4+ lymphocyte counting and virus load. The independent association of each risk factor with the disease was determined through a logistic regression model. Results: The 56, 5 % of the 154 patients presented Chronic Inflammatory Periodontal Disease; 60 (39.0% gingivitis and 27 (17,5% periodontitis. Gingivitis was associated with poor oral hygiene (OR: 3,71 and periodontitis with smoking habit (OR: 5,20. The severe forms of periodontitis occurred mainly in patients with lymphocyte counting lower than 500 cells/mm3 . Conclusions: The prevalence of Chronic Inflammatory Periodontal Disease in patients with HIV in Sancti Spiritus province is linked to known risk factors such as smoking habits and oral hygiene.

    Reducing health inequalities has become a major public health priority internationally. However, how best to achieve this goal is not well understood. Population health intervention research has the potential to address some of this knowledge gap. This review argues that simulation studies can produce unique evidence to build the population health intervention research evidence base on reducing social inequalities in health. To this effect, the advantages of using simulation models over other population health intervention research methods are discussed. Key questions regarding the potential challenges of developing simulation models to investigate population health intervention research on reducing social inequalities in health and the types of population health intervention research questions that can be answered using this methodology are reviewed. We use the example of social inequalities in coronary heart disease to illustrate how simulation models can elucidate the effectiveness of a number of 'what-if' counterfactual population health interventions on reducing social inequalities in coronary heart disease. Simulation models are a flexible, cost-effective, evidence-based research method with the capacity to inform public health policy-makers regarding the implementation of population health interventions to reduce social inequalities in health.

    Full Text Available In developed countries, it is very difficult to demonstrate the effectiveness of pneumococcal vaccines because the incidence of pneumococcal pneumonia is very low. Vaccination against pneumococci infection was advised for 1378 outpatients, over 60 years of age, with chronic respiratory disease for more than one year. Of these patients, those who responded affirmatively to the advice were vaccinated against pneumococci between August and November 2002. The effectiveness of vaccination was evaluated by means of a 2-year cohort-study, comparing the vaccinated group (647 with the non-vaccinated group (731. The variables analyzed were the frequency of onset of bacterial respiratory infection, hospitalization due to bacterial respiratory infection and onset of pneumococcal respiratory infection. The incidence of bacterial respiratory infection and the incidence of pneumococcal respiratory infection to have decreased in the following 2 years (17.4%, 0.9%, as compared to the previous year (25.9%, 3.1%, in the vaccinated group. Conversely, the frequency was higher in the following 2 years (14.4%, 0.9% as compared to the previous year (14.2%, 0.4% in the non-vaccinated group. This inter-group difference was statistically significant. Simultaneous vaccination against pneumococci and influenza virus also resulted in a significant reduction in the incidence of bacterial respiratory infection. No decrease was observed in the frequency of hospitalization. These results indicate that pneumococcal vaccine is useful for elderly patients with chronic respiratory disease and that its efficacy may be enhanced by simultaneous vaccination against influenza.

    Overview. The Centers for Disease Control and Prevention (CDC) health-related quality of life (HRQoL) indicators are widely used in the general population to determine the burden of disease, identify health needs, and direct public health policy. These indicators also allow the burden of illness to be compared across different diseases. Although Lyme disease has recently been acknowledged as a major health threat in the USA with more than 300,000 new cases per year, no comprehensive assessment of the health burden of this tickborne disease is available. This study assesses the HRQoL of patients with chronic Lyme disease (CLD) and compares the severity of CLD to other chronic conditions. Methods. Of 5,357 subjects who responded to an online survey, 3,090 were selected for the study. Respondents were characterized as having CLD if they were clinically diagnosed with Lyme disease and had persisting symptoms lasting more than 6 months following antibiotic treatment. HRQoL of CLD patients was assessed using the CDC 9-item metric. The HRQoL analysis for CLD was compared to published analyses for the general population and other chronic illnesses using standard statistical methods. Results. Compared to the general population and patients with other chronic diseases reviewed here, patients with CLD reported significantly lower health quality status, more bad mental and physical health days, a significant symptom disease burden, and greater activity limitations. They also reported impairment in their ability to work, increased utilization of healthcare services, and greater out of pocket medical costs. Conclusions. CLD patients have significantly impaired HRQoL and greater healthcare utilization compared to the general population and patients with other chronic diseases. The heavy burden of illness associated with CLD highlights the need for earlier diagnosis and innovative treatment approaches that may reduce the burden of illness and concomitant costs posed by this

    Sigal and Hassett published an article about Lyme disease in the EHP Supplements (Sigal and Hassett 2002), suggesting that chronic Lyme disease is "psychogenic." I do not think that Sigal and Hassett, non-psychiatrists, are qualified to speak about psychiatric matters. I, however, actually have had the disease, which they characterize as "medically unexplained," for over 25 years and have 15 years of experience as a patient advocate and educator. I beg to differ.

    An unusual case of early nephrotic syndrome without hypertension which slightly resolved after delivery is documented. Renal biopsy was performed postpartum and the diagnosis was focal and segmental glomerulosclerosis with moderate chronic renal changes. It is questioned whether the case was due to preeclampsia or was the initial diagnosis of chronic renal disease which was made during pregnancy. The role of renal biopsy in such cases is briefly discussed (Tab. 2, Ref. 15). Full Text (Free, PDF) www.bmj.sk.

    Chronic obstructive pulmonary disease (COPD) is actual pathology, when it forms the mixed hypoxemia. In the conditions of a chronic hypoxemia structures of organism with high level of metabolic processes, namely brain tissues, suffer. Character of defeat of the central nervous system at that pathology is insufficiently studied. In this article we studied and analysed the presence of such changes as depression, anxiety, cognitive impairment and features of neurologic semiotics at COPD in 50 patients.

    Patients with chronic kidney disease (CKD) develop bleeding and thrombotic tendencies, so the indication of anticoagulation at the onset of atrial fibrillation (AF) is complex. AF is the most common chronic cardiac arrhythmia, and thromboembolism and ischemic stroke in particular are major complications. In recent years, new oral anticoagulant drugs have been developed, and they have shown superiority over the classical AVK in preventing stroke, systemic embolism and bleeding risk, constituting an effective alternative to those resources.

    Pulmonary strongyloidiasis is an uncommon presentation of Strongyloides infection, usually seen in immunocompromised hosts. The manifestations are similar to that of acute exacerbation of chronic obstructive pulmonary disease (COPD). Therefore, the diagnosis of pulmonary strongyloidiasis could be challenging in a COPD patient, unless a high index of suspicion is maintained. Here, we present a case of Strongyloides hyperinfection in a COPD patient mimicking acute exacerbation, who was on chronic steroid therapy. PMID:27790284

    Meier, R

    1996-01-01

    The etiology of inflammatory bowel disease is still unknown. Several potential mechanisms are discussed. The etiological and therapeutic importance of nutrition is controversial. Though changes in dietary habits and incidence of inflammatory bowel disease during the last century were in parallel, no specific nutritional factor has been isolated. No dietary prophylaxis of inflammatory bowel disease is yet known; all dietary therapies in inflammatory bowel disease aim to improve nutritional support and to diminish inflammation by bowel rest. Children and adolescents gain in weight and height. Total parenteral nutrition will not substantially reduce disease activity and operation rates. Total parenteral nutrition can only be recommended in ulcerative colitis patients with severe disease in the initial phase and in Crohn's patients with severe malnutrition and intestinal complications. Enteral nutrition support is less effective in ulcerative colitis than in Crohn's disease. Reported remission rates on enteral nutrition are 25% for ulcerative colitis and up to 80% for Crohn. However, in active Crohn's disease enteral nutrition is less effective than standard therapy with methylprednisolone and sulfasalizine. It is generally believed that nutrition therapy in combination with drugs is the best treatment modality. There is no evidence to support the importance of any combination of the formula diets such as elemental, oligopeptide, or polymeric formulations. Administration of formula diets by nasogastric tubes all show similar remission rates. Whether newer diets supplemented with arginine, glutamine, omega-3-fatty acids or short chain fatty acids increase remission rates is not known. Further studies in this field are warranted.

    The objective of this study is to evaluate the predictive values of baseline thyroid-stimulating hormone and the rate of thyroid-stimulating hormone change within the euthyroid state on the development of chronic kidney disease. We conducted a longitudinal study in 17,067 Korean adults with normal thyroid function and no history of thyroid disease. Incident chronic kidney disease was defined as an estimated glomerular filtration rate chronic kidney disease or at the final visit in subjects without chronic kidney disease, divided by the observation period (years). Subjects were stratified into quintiles according to rates of thyroid-stimulating hormone change. During 86,583 person-years of follow-up (median follow-up 5.2 years), there were 561 incident cases of chronic kidney disease. The risk of incident chronic kidney disease was significantly higher in subjects with rapid increases (quintile 5) or decreases (quintile 1) in thyroid-stimulating hormone levels compared to the reference group (quintile 3). In fully adjusted models, the hazard ratios of quintiles 1 and 5 were 3.15 (95 % confidence interval 2.34 to 4.24; p chronic kidney disease. The development of chronic kidney disease is associated with the rate of changes in thyroid-stimulating hormone level rather than with baseline thyroid-stimulating hormone levels.

    Full Text Available Lyme disease has become a global public health problem and a prototype of an emerging infection. Both treatment-refractory infection and symptoms that are related to Borrelia burgdorferi infection remain subject to controversy. Because of the absence of solid evidence on prevalence, causes, diagnostic criteria, tools and treatment options, the role of autoimmunity to residual or persisting antigens, and the role of a toxin or other bacterial-associated products that are responsible for the symptoms and signs, chronic Lyme disease (CLD remains a relatively poorly understood chronic disease construct. The role and performance of family medicine in the detection, integrative treatment, and follow-up of CLD are not well studied either.

    Chagas disease, caused by Trypanosoma cruzi infection, is ranked as the most serious parasitic disease in Latin America and has huge potential to become a worldwide problem, due to increasing migration, and international tourism, as well as infectant transfer by blood contact and transfusion, intrauterine transfer, and organ transplantation. Nearly 30% of chronically-infected patients become symptomatic, often with a latency of 10-30 years, developing life-threatening complications. Of those, nearly 90% develop Chagas heart disease, while the others manifest gastrointestinal disease and neuronal disorders. Besides interrupting the infection cycle and chemo therapeutic infectant elimination, starting therapy early in symptomatic patients is important for counteracting the disease. This would be essentially supported by optimized patient management, involving risk assessment, early diagnosis and monitoring of the disease and its treatment. From economic and logistic viewpoints, the tools of laboratory medicine should be especially able to guarantee this. After summarizing the basics of chronic Chagas disease, such as the epidemiological data, the pathogenetic mechanisms thought to drive symptomatic Chagas disease and also treatment options, we present tools of laboratory medicine that address patient diagnosis, risk assessment for becoming symptomatic and guidance, focusing on autoantibody estimation for risk assessment and heart marker measurement for patient guidance. In addition, increases in levels of inflammation and oxidative stress markers in chronic Chagas disease are discussed.

  9. A Mitochondrial Perspective of Chronic Obstructive Pulmonary Disease Pathogenesis

    Shadel, Gerald S.

    2016-01-01

    Chronic obstructive pulmonary disease (COPD) encompasses several clinical syndromes, most notably emphysema and chronic bronchitis. Most of the current treatments fail to attenuate severity and progression of the disease, thereby requiring better mechanistic understandings of pathogenesis to develop disease-modifying therapeutics. A number of theories on COPD pathogenesis have been promulgated wherein an increase in protease burden from chronic inflammation, exaggerated production of reactive oxygen species and the resulting oxidant injury, or superfluous cell death responses caused by enhanced cellular injury/damage were proposed as the culprit. These hypotheses are not mutually exclusive and together likely represent the multifaceted biological processes involved in COPD pathogenesis. Recent studies demonstrate that mitochondria are involved in innate immune signaling that plays important roles in cigarette smoke-induced inflammasome activation, pulmonary inflammation and tissue remodeling responses. These responses are reviewed herein and synthesized into a view of COPD pathogenesis whereby mitochondria play a central role.

    Issues involving chronic disease prevention and management (CDPM) are prevalent in today's aging society, and suggestions for improvement are essential to treat this patient demographic effectively. This article addresses the use of wearable devices for the medical community to improve CDPM by relying on the accumulation of micro data. For the patient, we recognize that these devices can be an effective tool to facilitate real-time monitoring of their vital signs and activity levels. With real-time monitoring and earlier responses, individuals can benefit by preventing, delaying or reducing exacerbations of chronic diseases. Use of these devices also has great benefit to the person and has the potential to decrease the individual's emergency room visits, hospital admissions and re-admissions. As patients and their healthcare providers work together to identify cumulative trends in their micro data, transitions in care planning will be enhanced, further contributing to improved chronic disease management.

    To test the hypothesis that the angiotensin converting enzyme (ACE) genotype is associated with chronic beryllium disease (CBD) and disease severity, we studied 50 cases of CBD and compared their ACE genotype to that of two different control groups, consisting of: (1) 50 participants from a beryllium machining facility; and (2) 50 participants from a non-beryllium-associated workplace. We found no statistically significant difference in the frequency of the I or D allele or of the DD genotype among cases of CBD and either control group. The odds ratio (OR) for the CBD DD genotype as compared with the non-DD genotype was 1.58 (95% confidence interval [CI]: 0.68 to 3.66, p = 0.12) for the beryllium-exposed control group, and 1.09 (95% CI: 0.48 to 2.46, p = 0.56) for the non-beryllium-exposed controls. We found an association between serum ACE activity and the ACE genotype, with DD cases having the highest median serum ACE activity (p = 0.005). We evaluated the beryllium lymphocyte proliferation test (BeLPT), bronchoalveolar lavage (BAL) cell components, chest radiography, pulmonary function test results, and exercise physiology in our CBD cases. No statistically significant associations with these disease markers were found for the CBD cases with the DD genotype. Although the difference was not statistically significant, the DD cases had a shorter median duration of exposure to beryllium before diagnosis of CBD, and tended to have a weaker response in their blood and BAL BeLPT than did the non-DD cases. These findings may indicate that the ACE genotype is important in the immune response to beryllium and in progression to beryllium disease.

    Full Text Available Use of nanomaterials in manufactured consumer products is a rapidly expanding industry and potential toxicities are just beginning to be explored. Combustion-generated multiwall carbon nanotubes (MWCNT or nanoparticles are ubiquitous in non-manufacturing environments and detectable in vapors from diesel fuel, methane, propane, and natural gas. In experimental animal models, carbon nanotubes have been shown to induce granulomas or other inflammatory changes. Evidence suggesting potential involvement of carbon nanomaterials in human granulomatous disease, has been gathered from analyses of dusts generated in the World Trade Center disaster combined with epidemiological data showing a subsequent increase in granulomatous disease of first responders. In this review we will discuss evidence for similarities in the pathophysiology of carbon nanotube-induced pulmonary disease in experimental animals with that of the human granulomatous disease, sarcoidosis.

    Anemia of chronic disease (ACD) and iron deficiency anemia (IDA) are the most prevalent forms of anemia and often occur concurrently. Standard tests of iron status used in differential diagnosis are affected by inflammation, hindering clinical interpretation. In contrast, soluble transferrin receptor (sTfR) indicates iron deficiency and is unaffected by inflammation. Objectives of this prospective multicenter clinical trial were to evaluate and compare the diagnostic accuracy of sTfR and the sTfR/log ferritin index (sTfR Index) for differential diagnosis using the automated Access(®) sTfR assay (Beckman Coulter) and sTfR Index. We consecutively enrolled 145 anemic patients with common disorders associated with IDA and ACD. Subjects with IDA or ACD + IDA had significantly higher sTfR and sTfR Index values than subjects with ACD (P Index: 14 (using nmol/L) (or 1.03 using mg/L). The sTfR Index was superior to sTfR (AUC 0.87 vs. 0.74, P Index). Use of sTfR and the sTfR Index improves detection of IDA, particularly in situations where routine markers provide equivocal results. Findings demonstrate a significant advantage in the simultaneous determination of ferritin, sTfR and sTfR Index. Obtaining a ferritin level alone may delay diagnosis of combined IDA and ACD.

    Full Text Available John J HalperinDepartment of Neurosciences, Overlook Medical Center, Summit, NJ, USAAbstract: Lyme disease, infection with the tick-borne spirochete Borrelia burgdorferi, causes both specific and nonspecific symptoms. In untreated chronic infection, specific manifestations such as a relapsing large-joint oligoarthritis can persist for years, yet subside with appropriate antimicrobial therapy. Nervous system involvement occurs in 10%–15% of untreated patients and typically involves lymphocytic meningitis, cranial neuritis, and/or mononeuritis multiplex; in some rare cases, patients have parenchymal inflammation in the brain or spinal cord. Nervous system infection is similarly highly responsive to antimicrobial therapy, including oral doxycycline. Nonspecific symptoms such as fatigue, perceived cognitive slowing, headache, and others occur in patients with Lyme disease and are indistinguishable from comparable symptoms occurring in innumerable other inflammatory states. There is no evidence that these nonspecific symptoms reflect nervous system infection or damage, or that they are in any way specific to or diagnostic of this or other tick-borne infections. When these symptoms occur in patients with Lyme disease, they typically also subside after antimicrobial treatment, although this may take time. Chronic fatigue states have been reported to occur following any number of infections, including Lyme disease. The mechanism underlying this association is unclear, although there is no evidence in any of these infections that these chronic posttreatment symptoms are attributable to ongoing infection with B. burgdorferi or any other identified organism. Available appropriately controlled studies indicate that additional or prolonged courses of antimicrobial therapy do not benefit patients with a chronic fatigue-like state after appropriately treated Lyme disease. Keywords: Lyme disease, Borrelia burgdorferi, chronic, diagnosis, treatment, chronic

    Full Text Available Abstract Background Access to medical records on the Internet has been reported to be acceptable and popular with patients, although most published evaluations have been of primary care or office-based practice. We tested the feasibility and acceptability of making unscreened results and data from a complex chronic disease pathway (renal medicine available to patients over the Internet in a project involving more than half of renal units in the UK. Methods Content and presentation of the Renal PatientView (RPV system was developed with patient groups. It was designed to receive information from multiple local information systems and to require minimal extra work in units. After piloting in 4 centres in 2005 it was made available more widely. Opinions were sought from both patients who enrolled and from those who did not in a paper survey, and from staff in an electronic survey. Anonymous data on enrolments and usage were extracted from the webserver. Results By mid 2011 over 17,000 patients from 47 of the 75 renal units in the UK had registered. Users had a wide age range (90 yrs but were younger and had more years of education than non-users. They were enthusiastic about the concept, found it easy to use, and 80% felt it gave them a better understanding of their disease. The most common reason for not enrolling was being unaware of the system. A minority of patients had security concerns, and these were reduced after enrolling. Staff responses were also strongly positive. They reported that it aided patient concordance and disease management, and increased the quality of consultations with a neutral effect on consultation length. Neither patient nor staff responses suggested that RPV led to an overall increase in patient anxiety or to an increased burden on renal units beyond the time required to enrol each patient. Conclusions Patient Internet access to secondary care records concerning a complex chronic disease is feasible and popular

    Full Text Available Introduction: A dysfunctional autonomic nervous system (ANS has also been recognized as an important mechanism contributing to the poor outcome in CKD patients, with several studies reporting a reduction in heart rate variability (HRV. Objective: Evaluate the sympathovagal balance in patients with chronic kidney disease on conservative treatment. Methods: In a cross-sectional study, patients with CKD stages 3, 4 and 5 not yet on dialysis (CKD group and age-matched healthy subjects (CON group underwent continuous heart rate recording during two twenty-minute periods in the supine position (pre-inclined, followed by passive postural inclination at 70° (inclined period. Power spectral analysis of the heart rate variability was used to assess the normalized low frequency (LFnu, indicative of sympathetic activity, and the normalized high frequency (HFnu, indicative of parasympathetic activity. The LFnu/HFnu ratio represented sympathovagal balance. Results: After tilting, CKD patients had lower sympathetic activity, higher parasympathetic activity, and lower sympathovagal balance than patients in the CON group. Compared to patients in stage 3, patients in stage 5 had a lower LFnu/HFnu ratio, suggesting a more pronounced impairment of sympathovagal balance as the disease progresses. Conclusion: CKD patients not yet on dialysis have reduced HRV, indicating cardiac autonomic dysfunction early in the course of CKD.

    Gastroesophageal reflux disease (GERD) frequently occurs in association with chronic respiratory diseases although the casual link is not always clear. Several pathophysiological and experimental factors are considered to support a role for GERD in respiratory disease. Conversely, respiratory diseases and bronchodilator treatment can themselves exacerbate GERD. When cough or severe asthma is being investigated, GERD does not need to be systematically looked for and a therapeutic test with proton pump inhibitors is not always recommended. pH impedance monitoring is now the reference diagnostic tool to detect non acid reflux, a form of reflux for which proton pump inhibitor treatment is ineffective. Recent data have shown a potential role of GERD in idiopathic pulmonary fibrosis and bronchiolitis obliterans following lung transplantation, leading to discussions about the place of surgery in this context. However, studies using pH impedance monitoring are still needed to better understand and manage the association between GERD and chronic respiratory diseases.

    Highlights: •We investigated imaging findings on gadoxetic acid-enhanced MRI of HCCs without the typical enhancement pattern on multiphasic MDCT. •Most HCCs showed ancillary MR findings of typical HCC. •Considerable number of HCCs showed MR enhancement pattern of typical HCC. -- Abstract: Objective: The purpose of this study was to investigate the value of enhancement kinetics and ancillary imaging findings on gadoxetic acid-enhanced and diffusion-weighted (DW) MR imaging for diagnosing hepatocellular carcinomas (HCCs) without the typical enhancement pattern on contrast-enhanced multiphasic MDCT in patients with chronic liver disease. Materials and methods: Eighty-two surgically confirmed HCCs without the typical enhancement pattern (hypervascular in the arterial phase, followed by washout on the portal or equilibrium phases) on triple-phase MDCT were enrolled in this study. The patients were classified into four categories based on the CT density pattern of arterial and equilibrium phases (isodense–isodense, hypodense–hypodense, isodense–hypodense, and hyperdense–isodense) compared to liver parenchyma. Signal intensity of HCCs on T2-weighted images (T2WI), arterial phase, 3 min late-phase, hepatobiliary phase (HBP) and DW images with a b value of 800 s/mm{sup 2} were qualitatively evaluated, and ADC values were measured. Fisher's exact test and Chi-square test were used to compare the frequency and trend of hyperintensity on T2WI, hypointensity on HBP images, hyperintensity on DW images, and histopathologic grades between groups with different CT density patterns. Kruskal–Wallis test was used to compare the ADC value between groups. Results: Thirty and 52 HCCs were categorized as hypervascular (hyperdense–isodense) and non-hypervascular HCCs (3, isodense–isodense; 37, hypodense–hypodense; 12, isodense–hypodense), respectively. Most HCCs showed hyperintensity on T2WI (77/82, 93.9%) and DW images (81/82, 98.8%) and hypointensity on HBP

    AIM: Quality of life (QOL) is a concept that incorporates many aspects of life beyond "health". The chronic liver disease questionnaire (CLDQ) was developed to evaluate the impact of chronic liver diseases (CLD) on QOL. The objectives of this study were to translate and validate a liver specific questionnaire, the CLDQ.METHODS: The CLDQ was formally translated from the original version to Thai language with permission. The translation process included forward translation, back translation, cross-cultural adaptation and a pretest. Reliability and validity of the translated version was examined in CLD patients. Enrolled subjects included CLD and normal subjects with age- and sex-matched. Collected data were demography,physical findings and biochemical tests. All subjects were asked to complete the translated versions of CLDQ and SF-36, which was previously validated. Cronbach's alpha and test-retest were performed for reliability analysis. One-way Anova or non-parametric method was used to determine discriminant validity. Spearman's rank correlation was used to assess convergent validity. P-value <0.05 was considered statistically significant.RESULTS: A total of 200 subjects were recruited into the study, with 150 CLD and 50 normal subjects. Mean ages (SD) were 47.3(11.7) and 49.1(8.5) years, respectively. The number of chronic hepatitis: cirrhosis was 76:74, and the ratio of cirrhotic patients classified as Child A:B:C was 37(50%): 26(35%): 11(15%). Cronbach's alpha of the overall CLDQ scores was 0.96 and of all domains were higher than0.93. Item-total correlation was >0.45. Test-retest reliability done at 1 to 4 wk apart was 0.88 for the average CLDQ score and from 0.68 to 0.90 for domain scores. The CLDQ was found to have discriminant validity. The highest scores of CLDQ domains were in the normal group, scores were lower in the compensated group and lowest in the decompensated group. The significant correlation between domains of the CLDQ and SF-36 was found

    2005-01-01

    Symptoms of Gulf War Syndrome and chronic Lyme disease are very similar. Lyme disease is a condition which can be difficult to diagnose since one of the main features of the condition, the erythema migrans rash, may be absent or overlooked and serological testing for Lyme disease may be falsely negative. Symptoms of Lyme disease may not became apparent until years after exposure to the causative organism. Military personnel during training in the field are at risk of tick bites and it may be that those who developed Gulf War Syndrome entered the conflict with latent Lyme disease. There has been no systematic examination of Gulf War Syndrome sufferers for chronic Lyme disease and it is hypothesized that chronic Lyme disease has been overlooked as a cause of Gulf War Syndrome. To address this it is suggested that sufferers of Gulf War Syndrome or similar illnesses should be examined by physicians who have experience diagnosing and treating large numbers of patients with Lyme disease.

    2013-01-01

    The onset of chronic disease is often the prelude to the subsequent physiological and mental twilight in the aging population of modern society. While rates of obesity, specific types of cancer and cardiovascular disorders seem to be on the rise in this group, many new therapies have addressed diseases that have been largely untreatable in the past. Alzheimer's disease has also recently come to the forefront of ongoing maladies most typically associated with an aging population. Ironically, though, many people seem to be living longer than expected. Recent biochemical, nutritional and genomic approaches have been able to elucidate some of the complex mechanisms, which lead to chronic diseases associated with an aging population such as Alzheimer's, metabolic syndrome, tumor metastasis and cardiovascular disease. These diseases and their sequalae seem to be related in many respects, with the common culprit being the inflammatory environment created by the presence of excess fat - particularly within the vascular network. Although a substantial effort has been focused on the development of new-line therapeutics to address these issues, nutrition and overall fitness and their effects on stalling or potentially reversing the advent of these diseases has not been fully embraced in the research arena. This review discusses the role of the inflammatory environment in the development of chronic diseases in the aging population and also proposes a common pathology. The benefits that improvements and dedication in nutrition and fitness approaches may offer at the molecular level are also discussed.

    2006-01-01

    Chronic obstructive pulmonary disease is characterized by progressive and partially reversible airway obstruction. The innumerable complications that occur during the progression of the disease can affect the nutritional state of patients suffering from this illness. The objective of this study was to present a brief review of the literature regarding the nutrition therapy used in the treatment of chronic obstructive pulmonary disease. To that end, we performed a bibliographic search for related articles published within the last 18 years and indexed for the Literatura Latinoamericana y del Caribe en Ciencias de la Salud (LILACS, Latin American and Caribbean Health Sciences Literature) and Medline databases. Malnutrition is associated with a poor prognosis for patients with chronic obstructive pulmonary disease, since it predisposes such patients to infections, as well as reducing respiratory muscle force, exercise tolerance and quality of life. Despite the fact that such malnutrition is extremely common in chronic obstructive pulmonary disease patients, it should be recognized as an independent risk factor, since it can be modified through appropriate and efficacious diet therapy and monitoring. For patients with chronic obstructive pulmonary disease, nutrition therapy is initiated after the evaluation of the nutritional state of the patient, which identifies nutritional risk, thereby allowing the proper level of treatment to be established. In this evaluation, anthropometric and biochemical markers, as well as indicators of dietary consumption and body composition, should be used. The prescribed diet should contain appropriate proportions of macronutrients, micronutrients and immunonutrients in order to regain or maintain the proper nutritional state and to avoid complications. The physical characteristics of the diet should be tailored to the individual needs and tolerances of each patient. In the treatment of patients with chronic obstructive pulmonary disease

    Full Text Available Background and Aims: A growing pile of evidence supports the notion that pulmonary involvement is one of the extrahepatic manifestations of chronic hepatitis C virus (HCV infection. The objective of this study was to determine the prevalence of HCV infection in patients with chronic obstructive pulmonary disease (COPD, and vice versa.Methods: Two cross-sectional studies were performed: 1. A prevalence study of HCV infection among patients with COPD; 2. A prevalence study of COPD among patients with chronic HCV infection. COPD was diagnosed according to ATS/ERS guidelines. The prevalence of HCV infection in COPD group was compared with the result of a previous study which determined the prevalence of HCV infection in general population. Prevalence of COPD in patients with chronic HCV infection was also compared to those with chronic hepatitis B virus (HBV infection.Results: The study included 108 patients with COPD, 68 patients with chronic HCV infection, and 60 patients with chronic HBV infection. HCV infection was observed in 8.3% of patients with COPD, and 1.2% of the control subjects (P= 0.000. The prevalence of COPD among patients with chronic HCV and HBV infection was 17.6%, and 5%, respectively (P=0.03. Comparing COPD-positive and -negative chronic HCV patients for risk factors for COPD revealed that only the mean age was higher in COPD-positive patients (60.8±9.1 years vs. 46.5±11.5 years, P=0.000. In multivariate analysis, age was found to be the only independent predictor of COPD in HCV group.Conclusions: Patients with COPD have increased prevalence of HCV infection, and patients with HCV infection, have increased prevalence of COPD. COPD may be an extrahepatic disease associated with HCV infection.

    Chronic neurological diseases (CND) like amyotrophic lateral sclerosis (ALS), dementia or multiple sclerosis (MS) share a chronic progressive course of disease that frequently leads to the common pathological pathway of neurodegeneration, including neuroaxonal damage, apoptosis and gliosis. There is an ongoing search for biomarkers that could support early diagnosis of CND and help to identify responders to interventions in therapeutic treatment trials. Cerebrospinal fluid (CSF) is a promising source of biomarkers in CND, since the CSF compartment is in close anatomical contact with the brain interstitial fluid, where biochemical changes related to CND are reflected. We review recent advances in CSF biomarkers research in CND and thereby focus on markers associated with neurodegeneration.

    Mac Way, Fabrice; Lessard, Myriam; Lafage-Proust, Marie-Hélène

    2012-12-01

    Chronic kidney disease (CKD) alters the metabolism of several minerals, thereby inducing bone lesions and vessel-wall calcifications that can cause functional impairments and excess mortality. The histological bone abnormalities seen in CKD, known as renal osteodystrophy, consist of alterations in the bone turnover rate, which may be increased (osteitis fibrosa [OF]) or severely decreased (adynamic bone disease [AD]); abnormal mineralization (osteomalacia [OM]), and bone loss. Secondary hyperparathyroidism is related to early phosphate accumulation (responsible for FGF23 overproduction by bone tissue), decreased calcitriol production by the kidneys, and hypocalcemia. Secondary hyperparathyroidism is associated with OF. Other factors that affect bone include acidosis, chronic inflammation, nutritional deficiencies, and iatrogenic complications.

    Psychological ownership is rarely considered in health discourse related to chronic illness or disease state. Construction of identity is an important consideration within this framework. This autoethnographic study explores psychological ownership and identity related to prostate cancer and chronic illness. Conclusions about the nature of psychological ownership and identity were gathered from the relevant literature and personal experience. Themes include the patient-healthcare professional relationship and that psychological ownership is personal and grounded in an individual's sense of identity, control and perceived capacity to control illness or disease. Personal reflection through autoethnography guides discussion of psychological ownership and identity.

    In modern society, aging and chronic disease is becoming common phenomenon due to the increasing numbers of elderly patients. To best treat this growing segment of the population, medical care should be based on constant vital sign monitoring. In this study, we propose a mobile vital sign measurement and data collection system for chronic disease management.. And we implemented a middle ware using Multi-Agent platform in SOS (Self-Organizing System) platform that transmits patient clinical data for services. We also implemented a HL7 messaging interface for interoperability of clinical data exchange. We propose health services on a self-organized software platform.

    The objective of the present study was to estimate the diagnostic potential of the Luscher color test. A total of 1083 patients presenting with chronic somatic diseases were available for the psychodiagnostic examination. It was shown that the color test makes it possible to evaluate clinically significant psychological characteristics as well as dynamics of anxiety and stress-resistance in this group of patients. Specifically, in the cases of chronic somatic diseases, the test can be used as one of the psychodiagnostic methods especially for mass screening and in the situations when the application of the standard questionnaires encounters difficulties (for example, in the patients with disturbed cognitive functions).

    Biomarkers have an increasingly important clinical role in managing patients with heart failure as well as those with kidney disease, both common conditions with generally poor prognostic outcomes and huge impacts on healthcare economics. For patients with chronic heart failure, biomarkers have become centre place in streamlining diagnostic pathways as well as identifying those with worse prognosis. There is much interest in the role for biomarkers in identifying patients at risk of acute kidney injury, although a number of these currently remain as research tools or are in the early stages of evaluation in clinical practice. Patients with cardiorenal syndrome represent a particular challenge to the clinician, and recent studies have suggested a valuable clinical role for certain biomarkers in this setting, either on their own or in combination. This paper will focus on biomarkers with a current clinical role in patients with cardiorenal disease (natriuretic peptides and neutrophil gelatinase-associated lipocalin), although brief reference will be made to other biomarkers with potential future application.

    Full Text Available Pulmonary hypertension (PH is a common complication of interstitial lung diseases (ILDs, particularly in idiopathic pulmonary fibrosis and ILD associated with connective tissue disease. However, other lung diseases, such as combined pulmonary fibrosis and emphysema syndrome, pulmonary Langerhans cell histiocytosis, and lymphangioleiomyomatosis, may also include PH in their clinical manifestations. In all of these diseases, PH is associated with reduced exercise capacity and poor prognosis. The degree of PH in ILDs is typically mild-to-moderate. However, some of these patients may develop a disproportionate increase in PH that cannot be justified solely by hypoxia and parenchymal injury: this condition has been termed “out-of-proportion” PH. The pathogenesis of PH in these diseases is various, incompletely understood and may be multifactorial. The clinical suspicion (i.e. increased dyspnoea, low diffusion capacity and echocardiographic assessment are the first steps towards proper diagnosis of PH; however, right heart catheterisation remains the current gold standard for diagnosis of PH. At present, no specific therapies have been approved for the treatment of PH in patients with ILDs.

    Full Text Available The nutritional status in chronic kidney disease (CKD patients is a predictor of prognosis during the first period of dialysis. Serum albumin is the most commonly used nutritional marker. Another index is plasma amino acid profile. Of these, the plasma levels of branched chain amino acids (BCAA, especially valine and leucine, correlate well with nutritional status. Plasma BCAAs were evaluated along with albumin and C-reactive protein in 15 patients of early stages of CKD and 15 age- and sex-matched healthy controls. A significant decrease in plasma valine, leucine and albumin levels was observed in CKD patients when compared with the controls (P <0.05. No significant difference in C-reactive protein (CRP levels was observed between the two groups. Malnutrition seen in our CKD patients in the form of hypoalbuminemia and decreased concentrations of BCAA points to the need to evaluate the nutritional status in the early stages itself. Simple measures in the form of amino acid supplementation should be instituted early to decrease the morbidity and mortality before start of dialysis in these patients.

    There is a growing recognition that positive psychological functioning (which includes constructs such as optimism and hope) influences health. However, the understanding of these underlying mechanisms in relation to health is limited. Therefore, this review sought to identify what the scientific literature says about the influence of optimism and hope on chronic disease treatment. A search was conducted in the PsycINFO, Scopus, Pubmed, and Web of Science databases using the indexing terms optimism, hope, chronic diseases, randomized controlled trial, and treatment between 1998 and 2015. In the articles, we identified the most studied diseases in context, the assessment instruments used, the participant characteristics investigated, the results found, and the publication dates. From our analysis of the articles that met our inclusion criteria, it appears that the study of these constructs is recent and there is evidence that individuals with greater optimism and hope seek to engage in healthier behaviors, regardless of their clinical status, and that this contributes to chronic disease treatment. More research is needed so that targeted interventions can be carried out effectively in chronic disease treatment. PMID:28101071

  5. Chronic Lyme disease: misconceptions and challenges for patient management.

    Lyme disease, infection with the tick-borne spirochete Borrelia burgdorferi, causes both specific and nonspecific symptoms. In untreated chronic infection, specific manifestations such as a relapsing large-joint oligoarthritis can persist for years, yet subside with appropriate antimicrobial therapy. Nervous system involvement occurs in 10%-15% of untreated patients and typically involves lymphocytic meningitis, cranial neuritis, and/or mononeuritis multiplex; in some rare cases, patients have parenchymal inflammation in the brain or spinal cord. Nervous system infection is similarly highly responsive to antimicrobial therapy, including oral doxycycline. Nonspecific symptoms such as fatigue, perceived cognitive slowing, headache, and others occur in patients with Lyme disease and are indistinguishable from comparable symptoms occurring in innumerable other inflammatory states. There is no evidence that these nonspecific symptoms reflect nervous system infection or damage, or that they are in any way specific to or diagnostic of this or other tick-borne infections. When these symptoms occur in patients with Lyme disease, they typically also subside after antimicrobial treatment, although this may take time. Chronic fatigue states have been reported to occur following any number of infections, including Lyme disease. The mechanism underlying this association is unclear, although there is no evidence in any of these infections that these chronic posttreatment symptoms are attributable to ongoing infection with B. burgdorferi or any other identified organism. Available appropriately controlled studies indicate that additional or prolonged courses of antimicrobial therapy do not benefit patients with a chronic fatigue-like state after appropriately treated Lyme disease.

    Despite recent advancements in the treatment of coronary artery disease (CAD), it remains the number one cause of death in the world. While traditional risk factors partially account for the development of CAD, other novel risk factors have recently been implicated. Specifically, chronic inflammation has been postulated to play a role in the development and propagation of this disease. The purpose of this systematic review is to examine the available evidence to determine if patients with chronic inflammatory diseases have higher rates of cardiovascular disease. A MEDLINE search was conducted for articles published between 1980-2009. We focused on studies that assessed hard cardiovascular endpoints in subjects with chronic inflammatory conditions such as systemic lupus erythematosus, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, polymyositis/dermatomyositis, and inflammatory bowel disease. Although largely based on small studies, our review indicates that patients with chronic inflammatory conditions are likely at elevated risk for the development of CAD. Further research consisting of prospective cohort studies is needed to better quantify this risk.

    The impact of a payer-provided telephone-based chronic disease management program on medical expenditures was evaluated using claims data from 126,245 members in employer self-ensured health plans (16,224 with a chronic disease in a group enrolled in the self-management program, 13,509 with a chronic disease in a group not participating in the program). A random effects regression model controlling for retrospective risk, age, sex, and diagnosis with a chronic disease was used to determine the impact of program participation on market-adjusted health care expenditures. Further confirmation of results was obtained by an ordinary least squares model comparing market- and risk-adjusted costs to the length of participation in the program. Participation in the program is associated with an average annual savings of $1157.91 per enrolled member in health care expenditures. Savings increase with the length of participation in the program. The results support the use of telephone-based patient self-management of chronic disease as a cost-effective means to reduce health care expenditures in the working-age population.

    Full Text Available Objective: To describe chronic disease management programs active in Switzerland in 2007, using an exploratory survey. Methods: We searched the internet (Swiss official websites and Swiss web-pages, using Google, a medical electronic database (Medline, reference lists of pertinent articles, and contacted key informants. Programs met our operational definition of chronic disease management if their interventions targeted a chronic disease, included a multidisciplinary team (≥2 healthcare professionals, lasted at least six months, and had already been implemented and were active in December 2007. We developed an extraction grid and collected data pertaining to eight domains (patient population, intervention recipient, intervention content, delivery personnel, method of communication, intensity and complexity, environment, clinical outcomes. Results: We identified seven programs fulfilling our operational definition of chronic disease management. Programs targeted patients with diabetes, hypertension, heart failure, obesity, psychosis and breast cancer. Interventions were multifaceted; all included education and half considered planned follow-ups. The recipients of the interventions were patients, and healthcare professionals involved were physicians, nurses, social workers, psychologists and case managers of various backgrounds. Conclusions: In Switzerland, a country with universal healthcare insurance coverage and little incentive to develop new healthcare strategies, chronic disease management programs are scarce. For future developments, appropriate evaluations of existing programs, involvement of all healthcare stakeholders, strong leadership and political will are, at least, desirable.

    Chronic kidney disease (CKD) is an independent risk factor for the development of cardiovascular disease (CVD). Often, CKD and CVD coexist, and patients warrant optimal pharmacotherapy to reduce the risk of future cardiovascular (CV) events. Randomized trials have evaluated the role of antihypertensive therapy and lipid-lowering therapy as means to reduce CVD in patients with CKD. Many clinical trials support the role of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) in the CKD population. In addition, many clinical trials have evaluated the role of statin therapy in reducing CV events in early- and late-stage CKD. The struggle with interpreting results from these trials is that there are a number of different CV composite end points and a lack of consistency in defining CKD, especially in some post hoc subanalyses. Overall, ACEI/ARB therapy is supported by the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) and the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF KDOQI) hypertension guidelines and statin therapy is supported by the Adult Treatment Panel (ATP) III and NKF KDOQI dyslipidemia guidelines to optimally manage patients with CKD and CV risk factors. Questions remain as to the optimal role of statin therapy in patients with CKD receiving dialysis. JNC 8 and ATP IV guidelines will be available in the next year, and it is expected that there will be specific recommendations on both hypertension and dyslipidemia management in the CKD population.

    Full Text Available ABSTRACT Objective: To investigate the association between various chronic diseases, multimorbidity, and handgrip strength in community dwelling older adults in Southern Brazil. Methods: A cross-sectional study carried out with 477 older adults (60 years and older who resided in Antônio Carlos, Santa Catarina state. Subjects aged 60-79 years were selected by probability sampling (n=343 and all subjects aged 80 years or older (n=134 were evaluated. Chronic diseases were identified by self-report. A mechanical dynamometer verified handgrip strength (i.e., the outcome. Adjustments variables were age, literacy, living arrangement, smoking, body mass index, cognitive function, and comorbid chronic diseases. Sex-stratified analyses were conducted with simple and multiple linear regression. Results: A total of 270 women (73.2±8.8 years and 207 men (73.3±9.0 years were assessed. In the adjustment analysis, cancer (β=-3.69; 95%CI=-6.97 to -0.41 and depression (β=-1.65; 95%CI=-3.20 to -0.10 were associated with lower handgrip strength in women. For men, diabetes (β=-5.30; 95%CI=-9.64 to -0.95, chronic lung disease (β=-4.74; 95%CI=-7.98 to -1.50, and coronary heart disease (β=-3.07; 95%CI=-5.98 to -0.16 were associated with lower handgrip strength values. There was an inverse trend between number of diseases and handgrip strength for men only. Conclusion: The results showed an independent association between chronic diseases and handgrip strength. As such, handgrip strength is a valid measure to use for prevention or intervention in chronic disease and multimorbidity.

    The tick bite transmitted Lyme disease is one of the most common antropozoonosis, about 10 000 new infections are reported in Hungary each year. The progress and clinical presentation can vary, and carditis can occur in later stages. A serologically verified Lyme disease caused third degree atrioventricular block in young male presenting with presyncope. Based on the tick-bites mentioned a few weeks prior to hospital admission, Lyme carditis was considered with the administration of antibiotics and monitor observation. Typical skin lesions were not recognized and laboratory findings showed no pathology. An electrophysiological study recorded a predominant supra-His atrioventricular block. Total regression of conduction could be detected later and the serological tests established an underlying Lyme disease. Currently no definite treatment recommendation is available for the potentially reversible Lyme carditis. The tick bite seemed to be the key on our way to diagnosis; however, serological tests proved the disease to be older than one year. A detailed medical history and serological tests are essential in identifying the cause and pacemaker implantation can be avoided.

    2015-01-01

    Full Text Available Several million people with chronic liver diseases (cirrhosis, hepatitis show neurological alterations, named hepatic encephalopathy (HE with cognitive and motor alterations that impair quality of life and reduces life span. Inflammation acts synergistically with hyperammonemia to induce cognitive and motor alterations in patients with chronic liver disease and minimal hepatic encephalopathy (MHE. Previous studies in animal models have suggested that neuroinflammation is a major player in HE. This would also be the case in patients with liver cirrhosis or hepatitis C with HE. Rats with MHE show microglial activation and neuroinflammation that is associated with cognitive impairment and hypokinesia. The anti-inflammatory drug ibuprofen reduces microglial activation and neuroinflammation and restores cognitive and motor functions in rats with MHE. Chronic hyperammonemia per se induces neuroinflammation. Both peripheral inflammation and hyperammonemia would contribute to neuroinflammation in chronic liver failure. Therefore, neuroinflammation may be a key therapeutic target to improve the cognitive and motor alterations in MHE and overt HE. Identifying new targets to reduce neuroinflammation in MHE without inducing secondary effects would serve to develop new therapeutic tools to reverse the cognitive and motor alterations in patients with HE associated with chronic liver diseases.

    Full Text Available Chronic diseases are the major cause of morbidity and mortality worldwide and have shown increasing incidence rates among children in the last decades. Chronic illnesses in the pediatric population, even if well managed, affect social, psychological, and physical development and often limit education and active participation and increase the risk for health complications. The significant pediatric morbidity and mortality rates caused by chronic illnesses call for serious efforts toward better understanding of the pathogenesis of these disorders. Recent studies have shown the involvement of microRNAs (miRNAs in various aspects of major pediatric chronic non-neoplastic diseases. This review focuses on the role of miRNAs in four major pediatric chronic diseases including bronchial asthma, diabetes mellitus, epilepsy and cystic fibrosis. We intend to emphasize the importance of miRNA-based research in combating these major disorders, as we believe this approach will result in novel therapies to aid securing normal development and to prevent disabilities in the pediatric population.

    2010-01-01

    Mindfulness-based stress reduction (MBSR) is a structured group program that uses mindfulness meditation to improve well-being and alleviate suffering. This article reviews the impact of MBSR for people with chronic diseases. The review includes original research that was published in English and peer-reviewed and reported outcomes for adults with chronic diseases who had participated in an MBSR program. Fifteen studies were identified. Outcomes related to mental and physical health, well-being, and quality of life. The studies included different research designs, and used self-report and physiological outcome measures. Participants' clinical diagnoses included fibromyalgia, chronic pain, rheumatoid arthritis, type 2 diabetes, chronic fatigue syndrome, multiple chemical sensitivity, and cardiovascular diagnoses. All 15 studies found that participation in an MBSR program resulted in improvements. No negative change was reported between baseline and follow up. Outcomes in regard to specific variables were difficult to compare and equivocal. Overall, positive change predominated. Chronic diseases are associated with a range of unwelcome psychological and physical consequences. Participation in an MBSR program is likely to result in coping better with symptoms, improved overall well-being and quality of life, and enhanced health outcomes. As an adjunct to standard care, MBSR has potential for much wider application in Australian primary care settings.

    Although medical treatment and endoscopic interven-tions are primarily offered to patients with chronic pancreatitis, approximately 40% to 75% will ultimately require surgery during the course of their disease. Al-though pancreaticoduodenectomy has been considered the standard surgical procedure because of its favorable results on pain control, its high postoperative complica-tion and pancreatic exocrine or/and endocrine dysfunc-tion rates have led to a growing enthusiasm for duodenal preserving pancreatic head resection. The aim of this review is to better understand the rationale underlying of the Frey procedure in chronic pancreatitis and to ana-lyze its outcome. Because of its hybrid nature, combin-ing both resection and drainage, the Frey procedure has been conceptualized based on the pathophysiology of chronic pancreatitis. The short and long-term outcome, especially pain relief and quality of life, are better after the Frey procedure than after any other surgical proce-dure performed for chronic pancreatitis.

    2016-07-01

    Full Text Available In chronic kidney disease (CKD and end-stage renal disease patients cardiovascular disease is the main cause of morbidity and mortality, with incidence of cardiac related mortality increasing as renal function declines. Even after controlling for traditional cardiovascular risk factors such as smoking, age, gender, dyslipidaemia, and arterial hypertension, patients with CKD have a higher incidence of major cardiovascular events. CKD is characterised by the presence of many other non-traditional cardiovascular risk factors, such as chronic inflammation and accelerated atherosclerosis, oxidative stress, and especially, secondary hyperparathyroidism. This review will summarise the current evidence on vascular calcifications and valvular heart disease in CKD patients, from pathophysiology to therapeutic strategies.

    We report an adult male with classic propionic acidemia (PA) who developed chronic kidney disease in the third decade of his life. This diagnosis was recognized by an increasing serum creatinine and confirmed by reduced glomerular filtration on a (99m)Tc-diethylenetriamine pentaacetate (DTPA) scan. Histopathology of the kidney showed moderate glomerulo- and tubulointerstitial fibrosis with very segmental mesangial IgA deposits. This is the second reported case of kidney disease in an individual with propionic acidemia possibly indicating that chronic kidney disease may be a late-stage complication of propionic acidemia. Additionally, this is the first description of the histopathology of kidney disease in an individual with propionic acidemia. As more cases emerge, the clinical course and spectrum of renal pathology in this disorder will be better defined.
