    2010-01-01

    Full Text Available Spontaneous medastinal emphysema, as a complication of acute severe asthma, is an uncommon entity. It usually runs a benign course and resolves spontaneously without any surgical intervention. Recognition of this complication is critical, as it has to be differentiated from other life threatening ones including oesophageal rupture, Boerhave′s syndrome, acute coronary syndrome and pulmonary embolism. This case is being presented to emphasize its recognition in the differential diagnosis of complications arising from acute severe asthma and to present its management strategy in detail.

  2. Chapter 14: Acute severe asthma (status asthmaticus).

    Shah, Rachna; Saltoun, Carol A

    2012-01-01

    Acute severe asthma, formerly known as status asthmaticus, is defined as severe asthma unresponsive to repeated courses of beta-agonist therapy such as inhaled albuterol, levalbuterol, or subcutaneous epinephrine. It is a medical emergency that requires immediate recognition and treatment. Oral or parenteral corticosteroids should be administered to all patients with acute severe asthma as early as possible because clinical benefits may not occur for a minimum of 6-12 hours. Approximately 50% of episodes are attributable to upper respiratory infections, and other causes include medical nonadherence, nonsteroidal anti-inflammatory exposure in aspirin-allergic patients, allergen exposure (especially pets) in severely atopic individuals, irritant inhalation (smoke, paint, etc.), exercise, and insufficient use of inhaled or oral corticosteroids. The patient history should be focused on acute severe asthma including current use of oral or inhaled corticosteroids, number of hospitalizations, emergency room visits, intensive-care unit admissions and intubations, the frequency of albuterol use, the presence of nighttime symptoms, exercise intolerance, current medications or illicit drug use, exposure to allergens, and other significant medical conditions. Severe airflow obstruction may be predicted by accessory muscle use, pulsus paradoxus, refusal to recline below 30°, a pulse >120 beats/min, and decreased breath sounds. Physicians' subjective assessments of airway obstruction are often inaccurate. More objective measures of airway obstruction via peak flow (or forced expiratory volume in 1 second) and pulse oximetry before oxygen administration usually are helpful. Pulse oximetry values >90% are less commonly associated with problems although CO(2) retention and a low Pao(2) may be missed. PMID:22794687

    During the period 1973-85 assisted ventilation was used for the treatment of severe asthma on 48 occasions in 18 patients (one patient was ventilated 29 times). On each occasion arterial blood gas abnormalities were restored to normal as quickly as possible irrespective of peak inflation pressures. One patient was thought to be brain dead on transfer from another hospital but was ventilated for 48 hours while this diagnosis was confirmed. There was one episode of mediastinal emphysema. There ...

  5. Is ketamine a lifesaving agent in childhood acute severe asthma?

    Hendaus, Mohamed A; Jomha, Fatima A; Alhammadi, Ahmed H

    2016-01-01

    Children with acute severe asthma exacerbation are at risk of developing respiratory failure. Moreover, conventional aggressive management might be futile in acute severe asthma requiring intubation and invasive ventilation. The aim of this review is to detail evidence on the use of ketamine in childhood asthma exacerbations. A search of the MEDLINE, EMBASE, and Cochrane databases was performed, using different combinations of the following terms: ketamine, asthma, use, exacerbation, and childhood. In addition, we searched the references of the identified articles for additional articles. We then reviewed titles and included studies that were relevant to the topic of interest. Finally, the search was limited to studies published in English and Spanish from 1918 to June 2015. Due to the scarcity in the literature, we included all published articles. The literature reports conflicting results of ketamine use for acute severe asthma in children. Taking into consideration the relatively good safety profile of the drug, ketamine might be a reasonable option in the management of acute severe asthma in children who fail to respond to standard therapy. Furthermore, pediatricians and pediatric emergency clinicians administering ketamine should be knowledgeable about the unique actions of this drug and its potential side effects. PMID:26955277

    2009-09-01

    Full Text Available Abstract Acute severe asthma is one of the most common medical emergency situations in childhood, and physicians caring for acutely ill children are regularly faced with this condition. In this article we present a summary of the pathophysiology as well as guidelines for the treatment of acute severe asthma in children. The cornerstones of the management of acute asthma in children are rapid administration of oxygen, inhalations with bronchodilators and systemic corticosteroids. Inhaled bronchodilators may include selective b2-agonists, adrenaline and anticholinergics. Additional treatment in selected cases may involve intravenous administration of theophylline, b2-agonists and magnesium sulphate. Both non-invasive and invasive ventilation may be options when medical treatment fails to prevent respiratory failure. It is important that relevant treatment algorithms exist, applicable to all levels of the treatment chain and reflecting local considerations and circumstances.

    Blood gas measurements obtained during 35 episodes of acute, severe asthma in 19 children were analysed. Arterial carbon dioxide tension (PaCO2) was mean (SD) 5.7 (1.2) kPa and the arterial oxygen tension (PaO2) was 7.7 (1.1)kPa. Hypoxaemia was severe (PaO2 less than or equal to 7.9 kPa) on 19 occasions, was present alone (type I) on eight of these, and was associated with hypercapnia (type II) on 11. The PaO2 was similar in both the type I and type II subgroups, but PaCO2 was significantly h...

  13. Acute severe asthma: new approaches to assessment and treatment.

    2009-01-01

    The precise definition of a severe asthmatic exacerbation is an issue that presents difficulties. The term 'status asthmaticus' relates severity to outcome and has been used to define a severe asthmatic exacerbation that does not respond to and/or perilously delays the repetitive or continuous administration of short-acting inhaled beta(2)-adrenergic receptor agonists (SABA) in the emergency setting. However, a number of limitations exist concerning the quantification of unresponsiveness. Therefore, the term 'acute severe asthma' is widely used, relating severity mostly to a combination of the presenting signs and symptoms and the severity of the cardiorespiratory abnormalities observed, although it is well known that presentation does not foretell outcome. In an acute severe asthma episode, close observation plus aggressive administration of bronchodilators (SABAs plus ipratropium bromide via a nebulizer driven by oxygen) and oral or intravenous corticosteroids are necessary to arrest the progression to severe hypercapnic respiratory failure leading to a decrease in consciousness that requires intensive care unit (ICU) admission and, eventually, ventilatory support. Adjunctive therapies (intravenous magnesium sulfate and/or others) should be considered in order to avoid intubation. Management after admission to the hospital ward because of an incomplete response is similar. The decision to intubate is essentially based on clinical judgement. Although cardiac or respiratory arrest represents an absolute indication for intubation, the usual picture is that of a conscious patient struggling to breathe. Factors associated with the increased likelihood of intubation include exhaustion and fatigue despite maximal therapy, deteriorating mental status, refractory hypoxaemia, increasing hypercapnia, haemodynamic instability and impending coma or apnoea. To intubate, sedation is indicated in order to improve comfort, safety and patient-ventilator synchrony, while at the

    Severe asthma in children is characterized by sustained symptoms despite treatment with high doses of ICS or oral corticosteroids. Children with severe asthma may fall into two categories, difficult-to-treat asthma or severe therapy-resistant asthma. Difficult-to-treat asthma is defined as poor control due to an incorrect diagnosis or comorbidities, poor adherence due to adverse psychological or environmental factors. In contrast, treatment-resistant is defined as difficult asthma despite man...

  19. Acute bronchial asthma.

    2011-11-01

    Acute asthma is the third commonest cause of pediatric emergency visits at PGIMER. Typically, it presents with acute onset respiratory distress and wheeze in a patient with past or family history of similar episodes. The severity of the acute episode of asthma is judged clinically and categorized as mild, moderate and severe. The initial therapy consists of oxygen, inhaled beta-2 agonists (salbutamol or terbutaline), inhaled budesonide (three doses over 1 h, at 20 min interval) in all and ipratropium bromide and systemic steroids (hydrocortisone or methylprednisolone) in acute severe asthma. Other causes of acute onset wheeze and breathing difficulty such as pneumonia, foreign body, cardiac failure etc. should be ruled out with help of chest radiography and appropriate laboratory investigations in first time wheezers and those not responding to 1 h of inhaled therapy. In case of inadequate response or worsening, intravenous infusion of magnesium sulphate, terbutaline or aminophylline may be used. Magnesium sulphate is the safest and most effective alternative among these. Severe cases may need ICU care and rarely, ventilatory support. PMID:21769523

  20. Inhaled and intravenous treatment in acute severe and life-threatening asthma.

    Sellers, W F S

    2013-02-01

    Management of life-threatening acute severe asthma in children and adults may require anaesthetic and intensive care. The inhaled route for drug delivery is not appropriate when only small respiratory gas volumes are shifted; the i.v. route may be associated with greater side-effects. Magnesium sulphate i.v. has a place in acute asthma management because it is a mild bronchodilator, and has a stabilizing effect on the atria which may attenuate tachycardia occurring after inhaled and i.v. salbutamol. If intubation and ventilation are required, a reduction in bronchoconstriction by any means before and during these procedures should reduce morbidity. This narrative review aims to show strengths and weakness of the evidence, present controversies, and forward opinions of the author. The review contains a practical guide to the setting up, use and efficiency of nebulizers, metered dose inhalers, and spacers (chambers). It also presents a commonsense approach to the management of severe asthmatics in whom delay in bronchodilatation would cause clinical deterioration. When self-inhaled agents have had no effect, i.v. drugs may help avoid intubation and ventilation. The review includes suggestions for the use of inhaled anaesthetics, anaesthetic induction, and brief notes on subsequent ventilation of the lungs. PMID:23234642

    Biomarkers have been critical for studies of disease pathogenesis and the development of new therapies in severe asthma. In particular, biomarkers of type 2 inflammation have proven valuable for endotyping and targeting new biological agents. Because of these successes in understanding and marking type 2 inflammation, lack of knowledge regarding non-type 2 inflammatory mechanisms in asthma will soon be the major obstacle to the development of new treatments and management strategies in severe asthma. Biomarkers can play a role in these investigations as well by providing insight into the underlying biology in human studies of patients with severe asthma. PMID:27401625

    Severe asthma is a complex and heterogeneous phenotype where management can be challenging. While many patients with severe asthma respond to high-dose inhaled corticosteroids in combination with a long-acting β-agonist, there remains a significant subset of patients that require oral corticosteroids to control symptoms. Alternative therapies are needed to help reduce the need for continuous oral corticosteroids; however, there are currently very few effective options. Several new alternative...

  5. Mechanical ventilation for severe asthma.

    Leatherman, James

    2015-06-01

    Acute exacerbations of asthma can lead to respiratory failure requiring ventilatory assistance. Noninvasive ventilation may prevent the need for endotracheal intubation in selected patients. For patients who are intubated and undergo mechanical ventilation, a strategy that prioritizes avoidance of ventilator-related complications over correction of hypercapnia was first proposed 30 years ago and has become the preferred approach. Excessive pulmonary hyperinflation is a major cause of hypotension and barotrauma. An appreciation of the key determinants of hyperinflation is essential to rational ventilator management. Standard therapy for patients with asthma undergoing mechanical ventilation consists of inhaled bronchodilators, corticosteroids, and drugs used to facilitate controlled hypoventilation. Nonconventional interventions such as heliox, general anesthesia, bronchoscopy, and extracorporeal life support have also been advocated for patients with fulminant asthma but are rarely necessary. Immediate mortality for patients who are mechanically ventilated for acute severe asthma is very low and is often associated with out-of-hospital cardiorespiratory arrest before intubation. However, patients who have been intubated for severe asthma are at increased risk for death from subsequent exacerbations and must be managed accordingly in the outpatient setting. PMID:26033128

    This study compared the efficacy and safety of nebulized magnesium sulphate with salbutamol to normal saline with salbutamol as the initial treatment of severe acute asthma patients. The present study was designed as a randomized open controlled clinical trial. The study was conducted Mymensingh Medical College Hospital over a period of 11 months from December 2009 to October 2010. Patients admitted with severe acute asthma having inclusion criteria were the study population. Among 120 study population 60 were in salbutamol with magnesium sulphate group and 60 were in salbutamol with normal saline group. The study finding showed that peak flow at baseline was similar in two groups. At 10 minutes after nebulization, the mean±SD percentage increase in peak flow was greater in magnesium sulphate group (20±4%) than in the normal saline salbutamol group (13±3%). At 20 minutes the percentage increase in peak flow was greater in magnesium sulphate group (35±7%) than in the normal saline salbutamol group (24±6%) p value sulphate plus salbutamol group reached PEF near to 60% which is not in saline salbutamol group. There was no significant changed in respiratory rate, pulse rate, systolic, diastolic blood pressure and clinical evidence of unwanted adverse effect. PMID:23416800

  8. Traditional Therapies for Severe Asthma.

    Wang, Eileen; Hoyte, Flavia C L

    2016-08-01

    Severe asthma is a complex and heterogeneous disease. The European Respiratory Society and American Thoracic Society guidelines define severe asthma for patients 6 years or older as "asthma which requires treatment with high-dose inhaled corticosteroids…plus a second controller or systemic corticosteroids to prevent it from becoming 'uncontrolled' or which remains 'uncontrolled' despite this therapy." This article reviews available traditional therapies, data behind their uses in severe asthma, and varying recommendations. As various asthma endotypes and phenotypes are better understood and characterized, targeted therapies should help improve disease outcomes, efficacy, and cost-effectiveness. PMID:27401628

    2011-01-01

    Full Text Available Arformoterol, a long-acting beta-2 agonist, has a rapid onset and long duration of action. Its role as rescue medication in acute asthma attack is undetermined. To compare the efficacy and tolerability of arformoterol with salbutamol nebulization, a study was conducted among 50 patients with acute non-severe asthma. Patients were randomly assigned to group 1 (n = 25 and group 2 (n = 25 who received three doses of salbutamol and arformoterol nebulization, respectively, at 20-min intervals. The peak expiratory flow rate (PEFR was measured at the baseline and 5 min after each dose. The demographics and baseline characteristics were comparable between the two groups. The mean PEFR significantly increased in both these groups when compared with the baseline. The increases in the PEFR in two groups were similar after the third dose. The adverse effects in both these groups were minor. Arformoterol was as effective and safe as salbutamol in acute non-severe asthma.

  12. Chronic Infection and Severe Asthma.

    Carr, Tara F; Kraft, Monica

    2016-08-01

    Chronic bacterial infection is implicated in both the development and severity of asthma. The atypical bacteria Mycoplasma pneumoniae and Chlamydophila pneumoniae have been identified in the airways of asthmatics and correlated with clinical features such as adult onset, exacerbation risks, steroid sensitivity, and symptom control. Asthmatic patients with evidence of bacterial infection may benefit from antibiotic treatment directed towards these atypical organisms. Examination of the airway microbiome may identify microbial communities that confer risk for or protection from severe asthma. PMID:27401621

    As the overall prevalence of asthma has escalated in the past decades, so has the population of patients with severe asthma. This condition is often difficult to manage due to the relative limitation of effective therapeutic options for the physician and the social and economic burden of the disease on the patient.

  15. Eosinophilic bioactivities in severe asthma.

    Carr, Tara F; Berdnikovs, Sergejs; Simon, Hans-Uwe; Bochner, Bruce S; Rosenwasser, Lanny J

    2016-01-01

    Asthma is clearly related to airway or blood eosinophilia, and asthmatics with significant eosinophilia are at higher risk for more severe disease. Eosinophils actively contribute to innate and adaptive immune responses and inflammatory cascades through the production and release of diverse chemokines, cytokines, lipid mediators and other growth factors. Eosinophils may persist in the blood and airways despite guidelines-based treatment. This review details eosinophil effector mechanisms, surface markers, and clinical outcomes associated with eosinophilia and asthma severity. There is interest in the potential of eosinophils or their products to predict treatment response with biotherapeutics and their usefulness as biomarkers. This is important as monoclonal antibodies are targeting cytokines and eosinophils in different lung environments for treating severe asthma. Identifying disease state-specific eosinophil biomarkers would help to refine these strategies and choose likely responders to biotherapeutics. PMID:27386041

    Asthma is a heterogeneous disease that can be classified into different clinical endotypes, depending on the type of airway inflammation, clinical severity, and response to treatment. This article focuses on the eosinophilic endotype of asthma, which is defined by the central role that eosinophils play in the pathophysiology of the condition. It is characterized by persistently elevated sputum and/or blood eosinophils and by a significant response to treatments that suppress eosinophilia. Eosinophil activity in the airway may be more important than their numbers and this needs to be investigated. Transcriplomic or Metabolomic signatures may also be useful to identify this endotype.

    O'Toole, Jacqueline; Mikulic, Lucas; Kaminsky, David A

    2016-08-01

    The epidemiology and physiology of severe asthma are inherently linked because of varying phenotypes and expressions of asthma throughout the population. To understand how to better treat severe asthma, we must use both population data and physiologic principles to individualize therapies among groups with similar expressions of this disease.

  19. The role of rhinosinusitis in severe asthma

    Jang, An-Soo

    2013-01-01

    The prevalence of asthma is approximately 5% to 10% in the general population. Of these, approximately 5% to 10% are severe asthmatics who respond poorly to asthmatic drugs, including high-dose inhaled steroids. Severe asthmatics have persistent symptoms, frequent symptom exacerbation, and severe airway obstruction even when taking high-dose inhaled steroids. The medical costs of treating severe asthmatics represent ~50% of the total healthcare costs for asthma. Risk factors for severe asthma...

  20. Linkage and Genetic Association in Severe Asthma.

    Jones, Bridgette L; Rosenwasser, Lanny J

    2016-08-01

    A significant body of work in the genetics of asthma currently exists. However, current knowledge has not been clarifying in understanding the pathophysiology of asthma and therapeutic treatment of the disease. Severe asthma in adults and children is a significant burden in relation to disproportionate disease morbidity, mortality, and health utilization. This disease phenotype is not well understood; current effective treatment regimens are limited. Genetic studies may lead to improved understanding of the pathophysiology of severe asthma and identification of relevant subsets, which allow more targeted and effective therapies and the realization of Precision Medicine in asthma.

  1. Difficulties with neurological prognostication in a young woman with delayed-onset generalised status myoclonus after cardiac arrest due to acute severe asthma

    Arvind Rajamani

    2011-01-01

    Full Text Available Neurological prognostication in cardiac arrest survivors is difficult, especially when the primary etiology is respiratory arrest. Prognostic factors designed to have zero false-positive rates to robustly confirm poor outcome are usually inadequate to rule out poor outcomes (i.e., high specificity and low sensitivity. One of the least understood prognosticators is generalised status myoclonus (GSM, with case reports confusing GSM, isolated myoclonic jerks and post-hypoxic intention myoclonus (Lance Adams syndrome [LAS]. With several prognostic indicators (including status myoclonus having been validated in the pre-hypothermia era, their current relevance is debatable. New modalities such as brain magnetic resonance imaging (MRI and continuous electroencephalography are being evaluated. We describe here a pregnant woman resuscitated from a cardiac arrest due to acute severe asthma, and an inability to reach a consensus based on published guidelines, with a brief overview of myoclonus, LAS and the role of MRI brain in assisting prognostication.

  5. Psychosocial Factors in Severe Pediatric Asthma.

    Booster, Genery D; Oland, Alyssa A; Bender, Bruce G

    2016-08-01

    Asthma is the most common chronic illness among children in the United States and can impact nearly all aspects of functioning. Most research suggests that children with severe asthma display more emotional and behavioral problems than their healthy peers. These psychological difficulties are associated with increased risk for functional impairments and problematic disease course. Multidisciplinary teams that assess and treat these psychosocial factors using psychoeducational and behavioral interventions are important for children whose asthma is poorly controlled. Future research should examine the ways in which stress, emotions, and immune functions interact, so as to develop more preventative interventions. PMID:27401618

  6. Intravenous magnesium sulfate therapy in severe asthma

    Mohd. Al-Ajmi

    2007-01-01

    Full Text Available A 22-year-old female, known asthmatic since seven years, developed severe bronchospasm in the preop-erative period. Bronchospasm remained unresponsive to the inhaled beta-agonist plus anticholinergic, IV ami-nophylline and hydrocortisone but responded quickly with magnesium sulfate® ( PSI, KSA infusion 1.25gm in 100ml normal saline over 20 minutes and another 1.25 gm over next 30 minutes as the initial infusion showed improvement in her clinical symptoms. Within half an hour of administering the 1st infusion of magnesium sulfate (1.25 gm the respiratory rate started reducing, rhonchi became less, SpO 2 came upto 92% and re-mained always above 90%. Encouraged by this result IV magnesium sulfate 2.5 gm in 500 ml normal saline was infused over next 24 hours along with alternate salbutamol and ipratropium nebulization every 6 hourly. With this treatment regimen the patient became asymptomatic within next 24 hours with normal clinical parameters and FEV 1 value. Hence it may be concluded that IV magnesium sulfate can be considered for patients with acute severe asthma who do not respond to standard therapeutic medications.

  9. Effect of asthma severity on symptom perception in childhood asthma

    A.L.B. Cabral

    2002-03-01

    Full Text Available Individual ability to perceive airway obstruction varies substantially. The factors influencing the perception of asthma are probably numerous and not well established in children. The present study was designed to examine the influence of asthma severity, use of preventive medication, age and gender on the association between respiratory symptoms (RS and peak expiratory flow (PEF rates in asthmatic children. We followed 92 asthmatic children, aged 6 to 16 years, for five months. Symptom scores were recorded daily and PEF was measured twice a day. The correlations among variables at the within-person level over time were analyzed for each child and for the pooled data by multivariate analysis. After pooling the data, there was a significant (P<0.05 correlation between each symptom and PEF; 60% of the children were accurate perceivers (defined by a statistically significant correlation between symptoms and PEF across time for diurnal symptoms and 37% for nocturnal symptoms. The accuracy of perception was independent of asthma severity, age, gender or the use of preventive medication. Symptom perception is inaccurate in a substantial number of asthmatic children, independently of clinical severity, age, gender or use of preventive medication. It is not clear why some asthmatic patients are capable of accurately perceiving the severity of airway obstruction while others are not.

  10. Severe asthma and the omalizumab option

    Johnston Chambless

    2008-05-01

    Full Text Available Abstract Atopic diseases and asthma are increasing at a remarkable rate on a global scale. It is now well recognized that asthma is a chronic inflammatory disease of the airways. The inflammatory process in many patients is driven by an immunoglobulin E (IgE-dependent process. Mast cell activation and release of mediators, in response to allergen and IgE, results in a cascade response, culminating in B lymphocyte, T lymphocyte, eosinophil, fibroblast, smooth muscle cell and endothelial activation. This complex cellular interaction, release of cytokines, chemokines and growth factors and inflammatory remodeling of the airways leads to chronic asthma. A subset of patients develops severe airway disease which can be extremely morbid and even fatal. While many treatments are available for asthma, it is still a chronic and incurable disease, characterized by exacerbation, hospitalizations and associated adverse effects of medications. Omalizumab is a new option for chronic asthma that acts by binding to and inhibiting the effects of IgE, thereby interfering with one aspect of the asthma cascade reviewed earlier. This is a humanized monoclonal antibody against IgE that has been shown to have many beneficial effects in asthma. Use of omalizumab may be influenced by the cost of the medication and some reported adverse effects including the rare possibility of anaphylaxis. When used in selected cases and carefully, omalizumab provides a very important tool in disease management. It has been shown to have additional effects in urticaria, angioedema, latex allergy and food allergy, but the data is limited and the indications far from clear. In addition to decreasing exacerbations, it has a steroid sparing role and hence may decrease adverse effects in some patients on high-dose glucocorticoids. Studies have shown improvement in quality of life measures in asthma following the administration of omalizumab, but the effects on pulmonary function are

An estimated 5%–10% of the 300 million people worldwide who suffer from asthma have a severe form. Patients with eosinophilic airway inflammation represent approximately 40%–60% of this severe asthmatic population. This form of asthma is often uncontrolled, marked by refractoriness to standard therapy, and shows persistent airway eosinophilia despite glucocorticoid therapy. This paper reviews personalized novel therapies, more specifically benralizumab, a humanized anti-IL-5Rα antibody, while also being the first to provide an algorithm for potential candidates who may benefit from anti-IL-5Rα therapy.

  14. Survey of the management of acute asthma in children.

    Widger, J

    2009-12-01

    Acute asthma is one of the most common reasons for children presenting to the emergency department. International guidelines for the management of acute paediatric asthma are widely available. In this study we examined how acute asthma in children is managed across hospitals in Ireland and compared Irish practice with standard international guidelines. We surveyed 54 paediatricians across 18 centres in Ireland. A total of 30 (55.5%) individual paediatricians across 17 (94%) centres replied. The majority of centres had a written protocol for the management of acute asthma. A large number of centres use MDI and spacer devices in acute management although doses used varied widely. Only 29% of centres had written asthma action plans available from the emergency department and 53% had plans available from the ward. Irish practice is largely inline with established guidelines. A national asthma strategy could further help to improve asthma care.

  20. Mepolizumab for the reduction of exacerbations in severe eosinophilic asthma.

    Russell, Richard; Brightling, Christopher

    2016-06-01

    Asthma affects over 300 million people worldwide and is severe in 10% of sufferers. Severe asthma is associated with greater morbidity and mortality particularly as a consequence of frequent exacerbations. Advances in approaches to phenotype the heterogeneity of severe asthma has established the importance of eosinophilic inflammation and emerging new therapies are broadly designed to target T2-mediated eosinophilic inflammation with the aim to reduce exacerbation frequency. Here, we summarize the evidence that eosinophilic asthma is an important pheno(endo)type and identifies a group at risk of exacerbations; that established therapies reduce exacerbations, particularly in eosinophilic severe asthma; and discuss the role of mepolizumab, an IL-5 neutralising monoclonal antibody therapy, in reducing exacerbations in severe eosinophilic asthma compared to established and other emerging therapies.

    Full Text Available OBJECTIVE: To identify risk factors for death among patients with severe asthma. METHODS: This was a nested case-control study. Among the patients with severe asthma treated between December of 2002 and December of 2010 at the Central Referral Outpatient Clinic of the Bahia State Asthma Control Program, in the city of Salvador, Brazil, we selected all those who died, as well as selecting other patients with severe asthma to be used as controls (at a ratio of 1:4. Data were collected from the medical charts of the patients, home visit reports, and death certificates. RESULTS: We selected 58 cases of deaths and 232 control cases. Most of the deaths were attributed to respiratory causes and occurred within a health care facility. Advanced age, unemployment, rhinitis, symptoms of gastroesophageal reflux disease, long-standing asthma, and persistent airflow obstruction were common features in both groups. Multivariate analysis showed that male gender, FEV1 pre-bronchodilator < 60% of predicted, and the lack of control of asthma symptoms were significantly and independently associated with mortality in this sample of patients with severe asthma. CONCLUSIONS: In this cohort of outpatients with severe asthma, the deaths occurred predominantly due to respiratory causes and within a health care facility. Lack of asthma control and male gender were risk factors for mortality.

    Full Text Available OBJECTIVE: Studies assessing the characteristics and management of patients hospitalized with asthma have been limited to a small number of facilities and have evaluated short time periods. The present study evaluated long-term changes among hospitalized asthma patients at a large number of facilities. METHODS: This was a retrospective, hospital-based observational case series, designated the Study of Severe Asthma in Latin America and Spain, which was conducted in Spain and in eight Latin-American countries. We reviewed the hospital records of 3,038 patients (age range, 15-69 years hospitalized with acute severe asthma at one of nineteen tertiary-care hospitals in 1994, 1999 and 2004. RESULTS: Over time, the use of inhaled corticosteroids and long-acting β2 agonists increased significantly, whereas the use of theophylline as a controller medication decreased. The utilization of pulmonary function tests also increased. There was a significant reduction in the mean hospital stay (8.5 days, 7.4 days and 7.1 days in 1994, 1999 and 2004, respectively, p = 0.0001 and a significant increase in the mean of the lowest arterial pH at hospital admission. In contrast, there was a significant decrease in the proportion of cases in which PEF was determined in the emergency room (48.6% in 1994 vs. 43.5% in 2004, p = 0.0001. We found the quality of asthma management and care to be generally better in Spain than in Latin America. CONCLUSIONS: Although there have been certain improvements in the management of asthma between severe exacerbations and during hospitalization, asthma management remains suboptimal in Spain and, especially, in Latin America.OBJETIVO: Estudos que avaliem as características e o gerenciamento de pacientes asmáticos hospitalizados têm sido limitados a um número pequeno de serviços e a curtos períodos de duração.

    Vandeleur, M

    2009-09-01

    The aim was to develop and implement an evidence based guideline for the treatment of acute asthma using a metered dose inhaler and spacer combination. Children admitted to Cork University Hospital Paediatric Department with acute asthma were identified during two identical 2 month seasonal periods before (2005) and after (2006) implementation of the new guidelines in September 2006. Pre-intervention and post-intervention audits by case note review were performed to determine the impact of and compliance with this evidence-based guideline emphasising patient assessment, spacer delivered bronchodilator and specific discharge criteria. Patients had similar characteristics during the two study periods. There was a raised threshold for admission after guideline implementation with 11\\/52 patients having mild exacerbations in 2006, compared to 21\\/36 in 2005. Duration of admission was less in the post-implementation group for equivalent exacerbation severity e.g. for moderate severity; 28 hours in 2005, 23 hours in 2006. Duration of bronchodilator therapy was shorter in 2006 and more likely to be given by spacer device earlier for equivalent levels of severity e.g. for moderate exacerbations, in 2006 the average length of salbutamol therapy was 18 hours with 12 hours by spacer device, in 2005 the average length of therapy was 25 hours with 3 hours by spacer. There was earlier initiation of oral corticosteroids; the average time to administration was 56 minutes in 2006 and 227 minutes in 2005. There was an improved documentation of asthma education in 2006 e.g. inhaler technique was reviewed in 37\\/52 in 2006, 21\\/35 in 2005 and better use of written action plans.

  12. Reducing asthma attacks in patients with severe asthma: The role of bronchial thermoplasty.

    Dunn, Ryan; Wechsler, Michael E

    2015-01-01

    Asthma remains one of the most common diseases worldwide and results in significant societal health care costs and in morbidity and mortality to those afflicted. Despite currently available medications, 5-10% of patients with asthma have severe disease with debilitating symptoms and/or life-threatening exacerbations. Bronchial thermoplasty is a device-based therapy with proven efficacy in this subgroup of patients. Thus far, bronchial thermoplasty has been shown to reduce exacerbations and to improve important measures of asthma control. The purpose of this article is to review the pathophysiology of severe asthma, including the role of airway smooth muscle cells and the procedural aspects of bronchial thermoplasty, and to review the evidence behind this important therapy.

  17. ACUTE PANCREATITIS - THE SEVERE FORM

    Ioana Grigoras

    2005-01-01

    Full Text Available Acute pancreatitis is an acute inflammatory disease. Frequently it is a challenging condition for the surgeon and for the intensive care physician, taking into account that etiology is sometimes obscure, the pathophysiology is complex and incompletely understood, the timing of surgical treatment is still under debate and the general treatment is mostly supportive. The incidence is about 30 – 50 / 100.000 / year. In 80% of cases the disease is associated with interstitial edema, mild infiltration with inflammatory cells and intra- or peripancreatic fat necrosis. Evolution is benign and self-limited with proper treatment. The severe form occurs less frequent (15 - 20%, results in long lasting hospitalization and is associated with high mortality (30 - 40%, due to infected necrosis and multiple organ failure. Alcoholism and biliary disease account for 80% of cases. Rare etiologies of disease include metabolic factors (hypercalcemia, hyperlipoproteinemia, drug ingestion, obstructive factors (abdominal tumors, trauma, endoscopic retrograde cholecistopancreatography, and s.o., infections (viral, parasitic and hemodynamic factors. Postoperative pancreatitis is a complication after major abdominal surgery (abdominal aorta aneurism repair, extensive upper abdominal surgery, hepatic or cardiac transplant, so.. The common pathophysiological mechanism is pancreatic hypoperfusion. Acute pancreatitis is not a stable disease, being characterized by time-dependent stages with specific morphologic and clinical patterns. The terminology used to designate these stages is stated in the Ulm classification. Since the consensus Conference in Atlanta (1992 the severe form of acute pancreatitis is defined by the presence of organ dysfunction/failure or by the presence of local complications. The initiating event is the premature zymogene activation and the impairment of the exocytosis process with local consequences (ongoing tissue necrosis and general consequences

  18. Asthma is a risk factor for acute chest syndrome and cerebral vascular accidents in children with sickle cell disease

    Scott Paul J

    2005-01-01

    Full Text Available Abstract Background Asthma and sickle cell disease are common conditions that both may result in pulmonary complications. We hypothesized that children with sickle cell disease with concomitant asthma have an increased incidence of vaso-occlusive crises that are complicated by episodes of acute chest syndrome. Methods A 5-year retrospective chart analysis was performed investigating 48 children ages 3–18 years with asthma and sickle cell disease and 48 children with sickle cell disease alone. Children were matched for age, gender, and type of sickle cell defect. Hospital admissions were recorded for acute chest syndrome, cerebral vascular accident, vaso-occlusive pain crises, and blood transfusions (total, exchange and chronic. Mann-Whitney test and Chi square analysis were used to assess differences between the groups. Results Children with sickle cell disease and asthma had significantly more episodes of acute chest syndrome (p = 0.03 and cerebral vascular accidents (p = 0.05 compared to children with sickle cell disease without asthma. As expected, these children received more total blood transfusions (p = 0.01 and chronic transfusions (p = 0.04. Admissions for vasoocclusive pain crises and exchange transfusions were not statistically different between cases and controls. SS disease is more severe than SC disease. Conclusions Children with concomitant asthma and sickle cell disease have increased episodes of acute chest syndrome, cerebral vascular accidents and the need for blood transfusions. Whether aggressive asthma therapy can reduce these complications in this subset of children is unknown and requires further studies.

  3. Quantitative computed tomography imaging of airway remodeling in severe asthma.

    Grenier, Philippe A; Fetita, Catalin I; Brillet, Pierre-Yves

    2016-02-01

    Asthma is a heterogeneous condition and approximately 5-10% of asthmatic subjects have severe disease associated with structure changes of the airways (airway remodeling) that may develop over time or shortly after onset of disease. Quantitative computed tomography (QCT) imaging of the tracheobronchial tree and lung parenchyma has improved during the last 10 years, and has enabled investigators to study the large airway architecture in detail and assess indirectly the small airway structure. In severe asthmatics, morphologic changes in large airways, quantitatively assessed using 2D-3D airway registration and recent algorithms, are characterized by airway wall thickening, luminal narrowing and bronchial stenoses. Extent of expiratory gas trapping, quantitatively assessed using lung densitometry, may be used to assess indirectly small airway remodeling. Investigators have used these quantitative imaging techniques in order to attempt severity grading of asthma, and to identify clusters of asthmatic patients that differ in morphologic and functional characteristics. Although standardization of image analysis procedures needs to be improved, the identification of remodeling pattern in various phenotypes of severe asthma and the ability to relate airway structures to important clinical outcomes should help target treatment more effectively.

  13. Improving asthma severity and control screening in a primary care pediatric practice

    Sudhanthar, Sathyanarayan; Thakur, Kripa; Sigal, Yakov; Turner, Jane; Gold, Jonathan

    2016-01-01

    Asthma is the most commonly encountered chronic disease in children. Periodic assessment of asthma severity and control is an integral part of asthma management, but patients with uncontrolled asthma don't always schedule routine asthma care visits. The aim of this project was to improve asthma control and severity screening in a primary care setting by using a validated tool for all visits for patients with a diagnosis of asthma aged 4-21 years. Our QI team developed a protocol to administer the Asthma Control Test (TM), a validated questionnaire to assess asthma control. The stakeholders involved were the physicians, nursing staff, and the Health Information Team (HIT). All patients who had a prior diagnosis of asthma or with an asthma medication in their chart, who presented for any clinical visit including asthma were administered ACT. The staff scored the ACT and included the form in the encounter sheet so that the physicians can review the scores, address the asthma control, severity, and document in the chart. The number of patients whose asthma control was assessed improved from 10% per year to 85% after the three PDSA cycles. Administration of the tool did not impact the flow of the patients in a busy primary care practice. Screening asthma severity and control for patients diagnosed with asthma with a validated questionnaire when presenting for any chief complaint including asthma will help the provider address the severity and control of asthma symptoms in a timely manner and would potentially help prevent unwanted emergency department or urgent care usage.

    Children with problematic severe asthma (PA) are either difficult to treat because of the presence of aggravating factors or else severely resistant to therapy. We investigated a cohort of school-aged children with PA and compared these children to age-matched peers with controlled persistent asthma (CA). The aims were to characterize features of children suffering from PA and identify children who were severely resistant to therapy. In this cross-sectional, multicenter comparison of children with different manifestations of persistent asthma, PA was defined as insufficient asthma control despite level 4 treatment, according to GINA. The protocol included questionnaires, spirometry, methacholine provocation, measurement of fraction of nitric oxide in exhaled (FE(NO) ) and nasal air, blood sampling for inflammatory biomarkers and atopy, and computerized tomography of sinuses and lungs (in the PA group only). Of the 54 children with PA, 61% had therapy-resistant asthma, with the remaining being difficult to treat because of identified aggravating factors. Children with PA more often had parents with asthma (p=0.003), came from families with a lower socioeconomic status (p=0.01), were less physically active (p=0.04), and had more comorbidity with rhinoconjunctivitis (p=0.01) than did the 39 children with CA. The former also exhibited lower FEV(1) values (p=0.02) and increased bronchial hyper-responsiveness (p=0.01), but there were no differences in atopy (p=0.81) or FE(NO) (p=0.16). A non-invasive protocol, involving a standardized and detailed clinical characterization, revealed distinguishing features of children with PA and enabled the identification of children with therapy-resistant asthma.

  3. Greater severity of new onset asthma in allergic subjects who smoke: a 10-year longitudinal study

    Antic Tjana

    2011-01-01

    Full Text Available Abstract Background Little is known about the association between cigarette smoking and asthma severity. We assessed smoking as a determinant of disease severity and control in a cohort of clinic-referred allergic subjects who developed new onset asthma. Methods Allergic rhinitis subjects with no asthma (n = 371 were followed-up for 10 years and routinely examined for asthma diagnosis. In those who developed asthma (n = 152, clinical severity and levels of asthma control were determined. Among these subjects, 74 (48.7% were current smokers, 17 (11.2% former smokers, and 61 (40.1% never smokers. Results When comparing current or past smokers to never smokers they had a higher risk of severe asthma in the univariate analysis, which became non-significant in the multivariate analysis. On the other hand, the categories of pack-years were significantly related to severe asthma in a dose response relationship in both the univariate and multivariate analysis: compared to 0 pack years, those who smoked 1-10 pack-years had an OR(95% CI of 1.47(0.46-4.68, those who smoked 11-20 pack-years had an OR of 2.85(1.09-7.46 and those who smoked more than 20 pack-years had an OR of 5.59(1.44-21.67 to develop more severe asthma. Smokers with asthma were also more likely to have uncontrolled disease. A significant dose-response relationship was observed for pack-years and uncontrolled asthma. Compared to 0 pack years, those who smoked 1-10 pack-years had an OR of 5.51(1.73-17.54 and those who smoked more than 10 pack-years had an OR of 13.38(4.57-39.19 to have uncontrolled asthma. Conclusions The current findings support the hypothesis that cigarette smoking is an important predictor of asthma severity and poor asthma control.

    Full Text Available Backgrounds: All of Long-acting β2-agonists are beneficial in maintenance treatment of asthma but their use in relieving acute asthma attacks is not well known. The aim of this study was to compare rapid bronchodilatory effects of Salmeterol and Formoterol in patient with moderate to severe asthma.Methods: It was a randomized, double blind, cross-over study on 60 patients with moderate to severe asthma. Patients randomly received 50 micrograms of salmeterol or 18 micrograms of formoterol  and  after  one-week  washed  out  period  exchanged  their  medications. All  patients undergone spirometry for four times (before receiving the drugs, as well as 3, 30 and 60 minutes after drug inhalation and Forced Expiratory Volume in 1 second (FEV1, Forced Vital Capacity (FVC, FVC percentage predicted value, FEV1/FVC, Peak Expiratory Flow Rate (PEFR and PEFR percentage predicted value were measured.Results: Both medications could significantly increase FEV1/FVC and PEFR at 3, 30 and 60 minutes after inhalation (P<0.001 compared to baseline.Three minutes after inhalation of salmeterol and formoterol, FEV1 increased by 8.7% and 12.2% respectively. Formoterol was associated with more increase in the amounts of FEV1 compared to Salmeterol.Conclusion: This study showed that fromoterol has a more rapid onset of bronchodilating action compared with salmeterol at 3 minutes after inhalation. Both agents had significant increases in FEV1/FVC and PEFR compared to baseline with no significant differences between two drugs.

  5. Exhaled nitric oxide levels in childhood asthma: a more reliable indicator of asthma severity than lung function measurement?

    Piacentini, G L; Suzuki, Y; Bodini, A

    2000-04-01

    The level of exhaled nitric oxide (NO) has been demonstrated to reflect the degree of airway inflammation in patients with asthma and to be related to the severity of asthma, as well as to the efficacy of treatment. In contrast, lung function tests provide information about airway volumes and flows reflecting the level of airway obstruction, but do not allow any direct information about the degree of airway inflammation. Several studies have evaluated the relationships between the level of airway inflammation assessed by exhaled NO and the levels of airway obstruction and/or bronchial hyperresponsiveness in asthmatic adults and children. These studies highlight the complex pathophysiology of asthma and suggest that exhaled NO may have a promising role in addition to lung function measurement in the evaluation of asthma severity in children.

Nonselective kinase inhibitors, such as sunitinib and sorafenib, are known to be associated with acute pancreatitis. There are few case reports of severe acute pancreatitis induced by pazopanib treatment. We present a case of severe acute pancreatitis caused by pazopan...

  8. Severe asthma in school-age children: evaluation and phenotypic advances.

    Coverstone, Andrea; Bacharier, Leonard B; Fitzpatrick, Anne M

    2015-05-01

    Although the majority of children with asthma have a favorable clinical response to treatment with low to moderate doses of inhaled corticosteroids (ICS), a small subset of children have "severe" asthma characterized by ongoing symptoms and airway inflammation despite treatment with high doses of ICS and even oral corticosteroids. Although there is symptom heterogeneity in the affected children, children with severe asthma share the risk for adverse outcomes, including recurrent and potentially life-threatening exacerbations, which contribute to substantial economic burden. This article reviews current knowledge of severe asthma in school-age children (age 6-17 years) with a focus on recent literature published after January 2012. Clinical management approaches for children with severe asthma are discussed as well as current phenotyping efforts and emerging phenotypic-directed therapies that may be of benefit for subpopulations of children with severe asthma in the future.

    Hypereosinophilic asthma (HEA) is considered as a specific severe asthma phenotype. Whether eosinophils have a link with airway remodeling characterized by pathological (thickening of the basement membrane), functional (persistent airflow impairment and decline in lung function) and imaging features (increase airway wall thickness at CT scan) is still debated. In a one year prospective cohort of 142 severe asthma patients (according to IMI), 14 persistent HEA patients (defined by a persistent blood eosinophilia >500/mm(3) at two consecutive visits) were identified and compared with ten patients without any blood eosinophilia during the follow-up period (NEA, blood eosinophilia always Bronchial biopsies obtained at enrollment were stained for eosinophils (EG2) and basement membrane thickness (BM) was quantified. Imaging by CT scan acquisition was standardized and bronchial abnormalities quantified. ACQ score and exacerbations were prospectively recorded. HEA was not associated with preeminent features of airway remodeling assessed by airflow impairment (Best ever FEV1 values 97% ± 20 in HEA vs. 80 ± 24% in NEA, p = 0.020), decline of FEV1 (FEV1 Decline 40 ± 235 ml/y in HEA vs. 19 ± 40 ml/y in NEA, P = 0.319), submucosal abnormalities (BM thickness 7.80 ± 2.66 μm in HEA vs. 6.84 ± 2.59 in NEA, p = 0.37) and airway wall thickening at CT-scan (0.250 ± 0.036 mm vs. 0.261 ± 0.043, p = 0.92). Eosinophils blood count was inversely correlated with semiquantitative imaging score (rho -0.373, p = 0.039). Smoking history and positive skin prick tests were independent risk factors for increased BM thickening. Outcomes were similar in both populations (Control and exacerbations). Persistent HEA is not associated with evidences of airway remodeling. PMID:25592243

  10. Role of Sleep Apnea and Gastroesophageal Reflux in Severe Asthma.

    Rogers, Linda

    2016-08-01

    Gastroesophageal reflux and obstructive sleep apnea syndrome are conditions that practitioners have been encouraged to evaluate and treat as part of a comprehensive approach to achieving asthma control. In this review, the author looks at the evidence linking these two conditions as factors that may impact difficult-to-control asthma and looks critically at the evidence suggesting that evaluation and treatment of these conditions when present impacts asthma control.

  11. Neutrophilic and Pauci-immune Phenotypes in Severe Asthma.

    Panettieri, Reynold A

    2016-08-01

    Although 2 T-helper type 2 inflammation evokes airway hyperresponsiveness and narrowing, neutrophilic or pauci-immune asthma accounts for significant asthma morbidity. Viruses, toxicants, environmental tobacco smoke exposure, and bacterial infections induce asthma exacerbations mediated by neutrophilic inflammation or by structural cell (pauci-immune) mechanisms. Therapeutic challenges exist in the management of neutrophilic and pauci-immune phenotypes because both syndromes manifest steroid insensitivity. The recognition that neutrophil subsets exist and their functions are unique poses exciting opportunities to develop precise therapies. The conventional thought to target neutrophil activation or migration globally may explain why current drug development in neutrophilic asthma remains challenging. PMID:27401627

    Many children experiencing acute asthmatic episodes have chest radiographs, which may show lung hyperinflation, hypoinflation, or normal inflation. Lung hypoinflation may be a sign of respiratory fatigue and poor prognosis. To compare the clinical course in children with asthma according to the degree of lung inflation on chest radiographs. We conducted a retrospective study during a 24-month period (from July 1999 to July 2001) of children aged 0-17 years, who presented to a pediatric emergency department or outpatient clinic with an asthma exacerbation. Chest radiographs obtained at presentation were reviewed independently by three pediatric radiologists who were blinded to the admission status of the patient. The correlation between hypoinflation and hospital admission was assessed in three age groups: 0-2 years, 3-5 years, and 6-17 years. Hypoinflation on chest radiographs was significantly correlated with hospital admission for children aged 6-17 years (odds ratio 16.00, 95% confidence interval 1.89-135.43). The inter-reader agreement for interpretation of these radiographs was strong, with a kappa score of 0.76. Hypoinflation was not correlated with admission in younger children. Lung hypoinflation is associated with a greater likelihood of hospital admission in children aged 6 years or older. Therefore, hypoinflation was a poor prognostic sign and may warrant more aggressive therapy. (orig.)

  16. Noninvasive assessment of asthma severity using pulse oximeter plethysmograph estimate of pulsus paradoxus physiology

    Jenkins Cathy A

    2010-03-01

    Full Text Available Abstract Background Pulsus paradoxus estimated by dynamic change in area under the oximeter plethysmograph waveform (PEP might provide a measure of acute asthma severity. Our primary objective was to determine how well PEP correlates with forced expiratory volume in 1-second (%FEV1 (criterion validity and change of %FEV1 (responsiveness during treatment in pediatric patients with acute asthma exacerbations. Methods We prospectively studied subjects 5 to 17 years of age with asthma exacerbations. PEP, %FEV1, airway resistance and accessory muscle use were recorded at baseline and at 2 and 4 hours after initiation of corticosteroid and bronchodilator treatments. Statistical associations were tested with Pearson or Spearman rank correlations, logistic regression using generalized estimating equations, or Wilcoxon rank sum tests. Results We studied 219 subjects (median age 9 years; male 62%; African-American 56%. Correlation of PEP with %FEV1 demonstrated criterion validity (r = - 0.44, 95% confidence interval [CI], - 0.56 to - 0.30 and responsiveness at 2 hours (r = - 0.31, 95% CI, - 0.50 to - 0.09 and 4 hours (r = - 0.38, 95% CI, - 0.62 to - 0.07. PEP also correlated with airway resistance at baseline (r = 0.28 for ages 5 to 10; r = 0.45 for ages 10 to 17, but not with change over time. PEP was associated with accessory muscle use (OR 1.16, 95% CI, 1.11 to 1.21, P Conclusions PEP demonstrates criterion validity and responsiveness in correlations with %FEV1. PEP correlates with airway resistance at baseline and is associated with accessory muscle use at baseline and at 2 and 4 hours after initiation of treatment. Incorporation of this technology into contemporary pulse oximeters may provide clinicians improved parameters with which to make clinical assessments of asthma severity and response to treatment, particularly in patients who cannot perform spirometry because of young age or severity of illness. It might also allow for earlier recognition

  17. Harsh parent-child conflict is associated with decreased anti-inflammatory gene expression and increased symptom severity in children with asthma.

    Ehrlich, Katherine B; Miller, Gregory E; Chen, Edith

    2015-11-01

    Asthma is a chronic respiratory disorder that affects over 7 million children in the United States. Evidence indicates that family stressors are associated with worsening of asthma symptoms, and some research suggests that these stressful experiences engender changes in children's immune systems in ways that exacerbate airway inflammation and contribute to both acute and chronic asthma symptoms. We examined the association between observed experiences of parent-child conflict and the expression of signaling molecules involved in the transduction of anti-inflammatory signals that regulate airway inflammation and obstruction. Fifty-seven children and their parents participated in a conflict task, and coders rated interactions for evidence of harsh and supportive behaviors. Children reported on their perceptions of parental support and reported on their daily asthma symptoms for 2 weeks. We collected peripheral blood in children to measure leukocyte expression of messenger RNA for the glucocorticoid receptor and the β2-adrenergic receptor. Analyses revealed that harsh conflict behaviors were associated with decreased expression of both messenger RNAs and more severe asthma symptoms. Neither supportive behaviors nor perceived parental support was associated with gene expression or asthma symptoms. These findings suggest that harsh interactions with parents are associated with downregulation of key anti-inflammatory signaling molecules and difficulties breathing in children with asthma. Children with asthma who are also victims of maltreatment may be particularly susceptible to transcriptional changes in immune cells that could worsen asthma over time. PMID:26535943

    Good adherence to inhaled corticosteroid (ICS) therapy is essential for effective asthma control. The factors affecting ICS therapy adherence vary among individuals and countries. As few data on adherence have been reported in Korea, the factors influencing such adherence, and the clinical implications thereof, were evaluated in Korean asthma patients. A total of 185 asthma patients who had taken ICS regularly for over 1 year were randomly selected from the recently established domestic adult asthma cohort, COREA (Cohort for Reality and Evolution of Adult Asthma Korea). To obtain adherence to ICS, both prescription refill adherence and self-reported adherence over 1 year (these are objective and subjective measurements respectively) were assessed without any interventions that might affect patients' adherence to ICS. Patients' information such as age, sex, smoking history and number of medication taken, was collected. Assessment of asthma severity, pulmonary function tests, and asthma symptom score were performed to evaluate the possible clinical implication of adherence to ICS. Approximately half of the patients (50.9%) showed less than 80% of prescription refill adherence. There was a considerable discrepancy between prescription refill adherence and self-reported adherence especially in the patients whose refill adherence was under than 50%. Younger asthma patients showed lower adherence to ICS than did older (> or = 60 years old) patients. Higher asthma severity was significantly associated with lower refill adherence to ICS. However, asthma symptom scores and forced expiratory volume in 1 second (FEV(1)) values were not directly related with refill adherence. To improve asthma control in Korea, enhancement of adherence to ICS is critical: our findings emphasize the need to use objective measurements when adherence to asthma medication is to be assessed in clinical practice.

    U-BIOPRED is a European Union consortium of 20 academic institutions, 11 pharmaceutical companies and six patient organisations with the objective of improving the understanding of asthma disease mechanisms using a systems biology approach.This cross-sectional assessment of adults with severe asthma, mild/moderate asthma and healthy controls from 11 European countries consisted of analyses of patient-reported outcomes, lung function, blood and airway inflammatory measurements.Patients with severe asthma (nonsmokers, n=311; smokers/ex-smokers, n=110) had more symptoms and exacerbations compared to patients with mild/moderate disease (n=88) (2.5 exacerbations versus 0.4 in the preceding 12 months; pgastro-oesophageal reflux with lower lung function. Sputum eosinophil count was higher in severe asthma compared to mild/moderate asthma (median count 2.99% versus 1.05%; p=0.004) despite treatment with higher doses of inhaled and/or oral corticosteroids.Consistent with other severe asthma cohorts, U-BIOPRED is characterised by poor symptom control, increased comorbidity and airway inflammation, despite high levels of treatment. It is well suited to identify asthma phenotypes using the array of "omic" datasets that are at the core of this systems medicine approach. PMID:26357963

  9. Acute effects of air pollution on asthma hospitalization in Shanghai, China

    Air pollution has been accepted as an important contributor to asthma development and exacerbation. However, the evidence is limited in China. In this study, we investigated the acute effect of air pollution on asthma hospitalization in Shanghai, China. We applied over-dispersed generalized additive model adjusted for weather conditions, day of the week, long-term and seasonal trends. An interquartile range increase in the moving average concentrations of PM10, SO2, NO2 and BC on the concurrent day and previous day corresponded to 1.82%, 6.41%, 8.26% and 6.62% increase of asthmatic hospitalization, respectively. The effects of SO2 and NO2 were robust after adjustment for PM10. The associations appeared to be more evident in the cool season than in the warm season. Our results contribute to the limited data in the scientific literature on acute effects of air pollution on asthma in high exposure settings, which are typical in developing countries. - Highlights: • Few prior studies in China examine the effect of air pollution on asthma. • We found acute effect of air pollution on asthma hospitalization in Shanghai. • Our results contribute to limited data on air pollution and asthma in China. - Ambient air pollution increases the risk of asthma hospitalization in Shanghai, China

  10. Relapse following emergency treatment for acute asthma: can it be predicted or prevented?

    Ducharme, F M; Kramer, M S

    1993-12-01

    We prospectively followed 314 children discharged from a children's hospital emergency department (ED) following an asthma attack, to identify risk, factors for relapse, i.e. a second ED visit for asthma within the next 10 days. Parents were surveyed concerning their child's past medical history, drugs received prior to the index visit, triggering factors, physician availability, parental anxiety, and sociodemographic variables. Data on severity of the attack, emergency treatment, response to treatment and drugs prescribed on discharge were extracted from the medical record. Ninety-six of the 314 children (31%) relapsed, most (68%) within 24 hours. Using multiple logistic regression, a predictive model was developed on 211 patients ("test sample"). The best model contained two variables: (1) the number of ED visits for acute asthma in the previous year (odds ratio [OR] = 2.4 for 4 or more vs fewer visits, 95% CI = 1.3-4.4) and (2) the intake of an oral short-acting theophylline preparation during the course of the acute treatment (OR = 0.4, 95% CI = 0.2-0.7). The sensitivity, specificity and positive predictive values of this model for predicting relapse were 73, 53, and 40%, respectively. When applied to a second randomly selected "validation sample" of 103 children, sensitivity was 73%, specificity 50%, and PPV 41%, thus indicating the stability of the model. The model identifies the number of ED visits in the previous year as an important risk factor for relapse. It also suggests that oral short-acting theophylline may still have a role in the treatment of patients in whom the contribution of inflammation to airway obstruction is minimal. PMID:8263566

  12. [A new spacer, Babyhaler, for BDP inhalation therapy in severe infantile asthma].

    Yamada, Y; Yoshihara, S; Abe, T; Fukuda, N; Watanabe, M; Ono, M; Arisaka, O

    2000-11-01

    Recently, it has been recognized that airway inflammation is the most important pathogenesis of bronchial asthma, and inhaled corticosteroids therapy is effective for childhood asthma. However, using metered dose inhalers (MDI) of beclomethasone dipropionate (BDP) is difficult for infants. In this study, we administered BDP inhalation therapy with a new spacer, Babyhaler, for five cases of early childhood with severe infantile asthma that we could not control even by combination of theophylline round the clock (RTC) therapy and disodium cromoglycate (DSCG) + beta 2 stimulant (beta 2) regular use. We compared symptom score of asthma attack between the pre-treatment period (prior 2 weeks) and post-treatment period (following 8 weeks) of BDP inhalation therapy with Babyhaler. As a result, symptom score decreased significantly within 4 weeks after treatment of BDP with Babyhaler as compared with the score before treatment of BDP. These findings suggest that Babyhaler is useful for BDP inhalation therapy in infantile asthma. PMID:11193463

    Background Recent studies have shown that T helper type-2 (Th2) cells can induce the apoptosis of CD4+CD25+ Treg cells or resist the immunosuppressive effect of Treg cells.We hypothesize that an imbalance of Th2/Treg is present in patients with allergic asthma.Methods Twenty-two patients with mild asthma,17 patients with moderate to severe asthma,and 20 healthy donors were enrolled.All patients were allergic to house dust mites.The proportion of peripheral blood CD4+CD25+ Treg cells and Th2 cells were determined by flow cytometry.The concentration of interleukin (IL)-10,transforming growth factor (TGF)-β and IL-4 in plasma was determined by enzyme linked immunosorbent assay.In these subjects,peripheral blood mononuclear cells from 17 mild asthmatic patients,13 moderate to severe asthmatic patients and 14 healthy donors were acquired and expression of forkhead box P3 (Foxp3) and GATA-3 mRNA was detected by reverse-transcriptase polymerase chain reaction.Results Compared with healthy donors and patients with mild asthma,the percent of CD4+CD25+ Treg cells and plasma IL-10 levels were decreased in patients with moderate to severe asthma.There were no significant differences in Foxp3 mRNA expression among three groups,but a downward trend seen among patients with asthma.However,the percent of Th2 cells,IL-4 levels and expression of GATA-3 mRNA was markedly higher in patients with mild and moderate to severe asthma than in the control group.The ratio of Th2/Treg and their cytokines was increased in allergic asthma,especially for moderate to severe asthma.The ratio of GATA-3/Foxp3 mRNA was also increased in allergic asthma.In patients with moderate to severe asthma,the percentage of peripheral blood Treg cells was negatively correlated to the percentage of Th2 cells and IL-4 levels.Conclusions The decline of CD4+CD25+ Treg cells in patients with moderate to severe asthma may play an important role in progress of the disease.Furthermore,the deficiency of CD4+CD25+ Treg

    Full Text Available Abstract Background Multiple studies have linked fungal exposure to asthma, but the link to severe asthma is controversial. We studied the relationship between asthma severity and immediate type hypersensitivity to mold (fungal and non-mold allergens in 181 asthmatic subjects. Methods We recruited asthma patients aged 16 to 60 years at a University hospital and a nearby General Practice. Patients were categorized according to the lifetime number of hospital admissions for asthma (82 never admitted, 53 one admission, 46 multiple admissions. All subjects had allergy skin prick tests performed for 5 mold allergens (Aspergillus, Alternaria, Cladosporium, Penicillium and Candida and 4 other common inhalant allergens (D. pteronyssinus, Grass Pollen, Cat and Dog. Results Skin reactivity to all allergens was commonest in the group with multiple admissions. This trend was strongest for mold allergens and dog allergen and weakest for D. pteronyssinus. 76% of patients with multiple admissions had at least one positive mold skin test compared with 16%-19% of other asthma patients; (Chi squared p Conclusion These findings support previous suggestions that mold sensitization may be associated with severe asthma attacks requiring hospital admission.

  18. Therapy with omalizumab for patients with severe allergic asthma improves asthma control and reduces overall healthcare costs.

    Costello, R W

    2012-02-01

    BACKGROUND: Patients with asthma who have persistent symptoms despite treatment with inhaled steroids and long-acting beta agonists are considered to have severe asthma. Omalizumab is a monoclonal antibody directed against IgE, which is used as an add-on treatment for patients who have severe persistent allergic asthma. AIMS: The aim of this study was to assess the clinical benefit and healthcare utilisation of patients who responded to omalizumab therapy and to establish an overall cost implication. METHODS: This was an observational retrospective cohort study designed to investigate the effect of omalizumab on exacerbations of asthma before and after 6 months of treatment in Irish patients. RESULTS: Centres who had treated patients with severe allergic asthma for the 6 months prior and post omalizumab treatment were audited with a standardised assessment tool. Sixty-three (32 male) patients were studied. In the 6 months prior to omalizumab 41 of 63 (66%) had been hospitalised, and this fell to 15 of 63 (24%), p < 0.0001 in the 6 months after treatment was started. Hospital admissions reduced from 2.4 +\\/- 0.41 to 0.8 +\\/- 0.37 and the mean number of bed days occupied was reduced from 16.6 +\\/- 2.94 to 5.3 +\\/- 2.57 days, p < 0.001. The number of oral corticosteroid doses used fell from 3.1 +\\/- 0.27 to 1.2 +\\/- 0.17, p < 0.001. The overall cost saving per omalizumab responder patients for 6 months was 834. CONCLUSIONS: Six months therapy with omalizumab reduced the number of bed days, the number of hospitalisations and the use of oral corticosteroids compared to the 6 months prior to commencement. Despite the cost of the additional therapy there were overall savings in health costs.

    2003-05-01

    Montelukast, a specific cysteinyl leukotriene receptor antagonist, has been shown to improve pulmonary function within 1 h of ingestion. This study was undertaken to compare the effects on peak expiratory flow rate (PEFR) of oral montelukast added to intravenous steroid, intravenous steroid alone and placebo during the 24 h period following administration. Seventy asthmatic patients (FEV1 40-80% predicted and > or = 15% improvement after inhaled beta agonist) were enrolled in a single blind study to receive oral montelukast (10 mg) plus intravenous prednisolone (1 mg/kg), intravenous prednisolone (1 mg/kg) or placebo in a randomised fashion. The patients received one ofthe above three groups of medication before any other treatments. This was immediately followed by the aerosol treatments of 100 mcg of terbutaline sulphate divided into three doses during 1 h as described in the consensus statement. Thereafter, patients were observed for 24 h to document the effects on PEFR, Borg dyspnoea score and need for rescue medication. The primary end point was percentage change at different time points. Secondary end points were Borg dyspnoea score and use of rescue medication. Compared with placebo, montelukast added to the prednisolone group and the prednisolone alone group had significant percentage change from baseline in PEFR in the entire 24 h period (P<0.05). The difference in PEFR between montelukast plus prednisolone group and prednisolone group favoured the montelukast plus prednisolone group but did not reach statistical significance. Furthermore, montelukast plus prednisolone group required less inhaled short-acting beta agonistthan other two groups. The results of this study indicate that adding montelukast to steroid in acute asthma may have some additive improvement in lung functions. PMID:12735671

  20. Asthma

    2011-11-01

    Full Text Available Abstract Asthma is the most common respiratory disorder in Canada. Despite significant improvement in the diagnosis and management of this disorder, the majority of Canadians with asthma remain poorly controlled. In most patients, however, control can be achieved through the use of avoidance measures and appropriate pharmacological interventions. Inhaled corticosteroids (ICSs represent the standard of care for the majority of patients. Combination ICS/long-acting beta2-agonists (LABA inhalers are preferred for most adults who fail to achieve control with ICS therapy. Allergen-specific immunotherapy represents a potentially disease-modifying therapy for many patients with asthma, but should only be prescribed by physicians with appropriate training in allergy. Regular monitoring of asthma control, adherence to therapy and inhaler technique are also essential components of asthma management. This article provides a review of current literature and guidelines for the appropriate diagnosis and management of asthma.

    2005-01-01

    Objective:To study the pathogenesis of acute lung injury in severe acute pancreatitis (SAP). Methods:Rats were sacrificed at 1, 3, 5, 6, 9 and 12 h after establishment of inducing model. Pancreas and lung tissues were obtained for pathological study, microvascular permeability and MPO examination. Gene expressions of TNF-α and ICAM-1 in pancreas and lung tissues were detected by RT-PCR. Results:After inducing SAP model, the injury degree of the pancreas and the lung increased gradually, accompanied with gradually increased MPO activity and microvascular permeability. Gene expressions of TNF-α and ICAM-1 in pancreas rose at 1 h and reached peak at 7 h. Relatively, their gene expressions in the lungs only rose slightly at 1 h and reached peak at 9-12 h gradually. Conclusion:There is an obvious time window between SAP and lung injury, when earlier protection is beneficial to prevent development of acute lung injury.

  2. Sputum interleukin-17 is increased and associated with airway neutrophilia in patients with severe asthma

    SUN Yong-chang; ZHOU Qing-tao; YAO Wan-zhen

    2005-01-01

    @@ Asthma is a chronic inflammatory airway disease characterized by the involvement of many cells (including eosinophils, mast cells, T cells, neutrophils and airway epithelial cells) and their cellular components.1 While airway eosinophilic inflammation is considered as a characteristic of asthma, our previous reports2,3 and other recent studies4,5 have demonstrated that neutrophils may play important roles in airway inflammation, or even in airway remodeling, particularly in severe asthma. The mechanisms underlying the neutrophil accumulation in asthmatic airway remain to be elucidated. Interleukin-8 (IL-8) is a potent chemotactic factor for neutrophils, and was demonstrated to be increased in asthmatic airways.6,7 More recent studies have shown that T-cell derived IL-17 can accumulate neutrophils via a IL-8 dependent pathway.8,9 Whether IL-17/IL-8 mechanism is involved in airway inflammation in severe asthma is not clear.

  4. The influence of asthma onset and severity on malocclusion prevalence in children and adolescents

    Luiz Sekio Tanaka

    2012-02-01

    Full Text Available OBJECTIVE: The influence of asthma, its severity levels and onset time on malocclusion occurrence were investigated. METHODS: The sample was composed by 176 children/adolescents, of both genders, aged 3 to 15 years, that were divided in two groups. The asthma group (AG enrolled 88 children/adolescents that were seen at the Breathe Londrina Program. The asthma-free group (AFG enrolled 88 preschool and school children recruited in 2 public schools. Malocclusion diagnosis was made according to WHO criteria (OMS, 1999. RESULTS: A higher prevalence in malocclusions in asthmatic patients in mixed dentition was observed when compared to controls (p0.05 and permanent dentition (p>0.05. A significant association was seen between asthma onset time and marked maxillary overjet (p<0.05, and open bite (p<0.05 in the mixed dentition, being both conditions more common among those that have presented the symptoms of asthma prior to 12 months of age. CONCLUSION: The results of this study indicate that the early manifestation of asthma at first year of life can cause dentofacial changes. Therefore, the prompt diagnostic of the illness, as well as the establishment of a proper therapy could improve the symptoms and chronic complications of asthma and also reduce its impact on craniofacial development.

    Bronchial thermoplasty is a young yet promising treatment for severe asthma whose benefit for long-term asthma control outweighs the short-term risk of deterioration and hospitalisation in the days following the treatment. It is an innovative treatment whose clinical efficacy and safety are beginning to be better understood. Since this is a device-based therapy, the overall evaluation of risk-benefit is unlike that of pharmaceutical products; safety aspects, regulatory requirements, study des...

  6. The Efficacy of Tiotropium as a Steroid-Sparing Agent in Severe Asthma

    Anmol S Kapoor

    2009-01-01

    Full Text Available People with severe asthma account for 5% to 10% of all asthmatic patients; however, this small group uses the majority of health care resources. Novel methods are needed to cope with the burden that this minority of patients places on the health care system. A severe asthma clinic patient, who was monitored through the University of Alberta’s Virtual Asthma Clinic (Edmonton, Alberta is presented. Despite optimization of his disease and individualized asthma education (provided by a certified asthma educator, the patient remained on oral glucocorticosteroids (OGS to control his disease. Following optimization and stabilization, a further reduction in the dose of his OGS by the addition of the long-acting anticholinergic agent tiotropium bromide, was demonstrated. The role of tiotropium as a potential ‘steroid-sparing agent’ in severe refractory asthma is discussed, noting that if patients who are on OGS are not monitored for active inflammation, they may overuse the amount of prescribed systemic steroids, which can result in long-term steroid-related sequelae.

    2014-10-01

    Full Text Available Background: The single most dreaded complication in severe malaria is cerebral malaria, but extracerebral serious complications are becoming frequent in endemic areas, which include hepatic dysfunctions with jaundice. Materials and Methods: This prospective case series study was undertaken to observe the clinical profile in 81cases of complicated malaria presenting with jaundice out of 344 hospitalized patients diagnosed with acute severe malaria. Liver function tests were assessed and the patients were followed up to 4 weeks. Results: 85% cases with jaundice had Plasmodium falciparum (Pf infection. Significant findings included a predominantly hemolytic jaundice (mean bilirubin 7.6 mg%, unconjugated 4.83 mg%, conjugated 2.79 mg%, raised ALT > AST (mean 101.2 vs.74.7 iu and a mean prothrombin time of 3 sec > control. Acute renal failure was common (77%. No residual hepatic dysfunctions were detected in survivors on follow-up. Mortality was 10%, mostly due to delayed diagnosis and associated serious co-morbid conditions. Conclusion: Differentiating fulminant viral hepatitis with multi-organ failure and early treatment of associated complications are crucial to reduce mortality in malaria presenting with jaundice. Hemolytic jaundice with mild and relatively early reversibility of hepatocellular dysfunction usually points towards complicated Pf malaria. Histologically, there is mild hepatic derangement. Acute renal failure is commonly associated. Vivax malaria can also cause hepatic dysfunctions. Mere presence of jaundice does not increase mortality compared to those without jaundice

  9. Potentially pathogenic airway bacteria and neutrophilic inflammation in treatment resistant severe asthma.

    Benjamin J Green

    Full Text Available Molecular microbiological analysis of airway samples in asthma has demonstrated an altered microbiome in comparison to healthy controls. Such changes may have relevance to treatment-resistant severe asthma, particularly those with neutrophilic airway inflammation, as bacteria might be anticipated to activate the innate immune response, a process that is poorly steroid responsive. An understanding of the relationship between airway bacterial presence and dominance in severe asthma may help direct alternative treatment approaches.We aimed to use a culture independent analysis strategy to describe the presence, dominance and abundance of bacterial taxa in induced sputum from treatment resistant severe asthmatics and correlate findings with clinical characteristics and airway inflammatory markers.Induced sputum was obtained from 28 stable treatment-resistant severe asthmatics. The samples were divided for supernatant IL-8 measurement, cytospin preparation for differential cell count and Terminal Restriction Fragment Length Polymorphism (T-RFLP profiling for bacterial community analysis.In 17/28 patients, the dominant species within the airway bacterial community was Moraxella catarrhalis or a member of the Haemophilus or Streptococcus genera. Colonisation with these species was associated with longer asthma disease duration (mean (SD 31.8 years (16.7 vs 15.6 years (8.0, p = 0.008, worse post-bronchodilator percent predicted FEV1 (68.0% (24.0 vs 85.5% (19.7, p = 0.025 and higher sputum neutrophil differential cell counts (median (IQR 80% (67-83 vs 43% (29-67, p = 0.001. Total abundance of these organisms significantly and positively correlated with sputum IL-8 concentration and neutrophil count.Airway colonisation with potentially pathogenic micro-organisms in asthma is associated with more severe airways obstruction and neutrophilic airway inflammation. This altered colonisation may have a role in the development of an asthma phenotype

  11. A study of air pollutants and acute asthma exacerbations in urban areas: status report

    Details of a study to investigate the possible roles of a variety of hazardous air pollutants on asthma exacerbations at ambient air concentrations. - A study to try to better understand the interactions between various air contaminants and acute asthma exacerbations is described. The study evaluates temporal associations between a panel of air contaminants and acute asthmatic exacerbations as measured by emergency room visits for asthma in communities in the Bronx and Manhattan in New York City (NYC). In addition, ambient levels of various air pollutants in two NYC communities are being compared. Almost 2 years of daily data have been collected for most of the air contaminants to be investigated. The air contaminants measured include gaseous compounds (ozone, sulfur dioxide, nitrogen oxides, aldehydes, nitrous acid, nitric acid, hydrochloric acid and ammonia), particulate matter components (metals, elemental and organic carbon, sulfate, hydrogen ion, pollen, mold spores and particle mass and number)

  14. Pooled Sequencing of Candidate Genes Implicates Rare Variants in the Development of Asthma Following Severe RSV Bronchiolitis in Infancy.

    Dara G Torgerson

    Full Text Available Severe infection with respiratory syncytial virus (RSV during infancy is strongly associated with the development of asthma. To identify genetic variation that contributes to asthma following severe RSV bronchiolitis during infancy, we sequenced the coding exons of 131 asthma candidate genes in 182 European and African American children with severe RSV bronchiolitis in infancy using anonymous pools for variant discovery, and then directly genotyped a set of 190 nonsynonymous variants. Association testing was performed for physician-diagnosed asthma before the 7th birthday (asthma using genotypes from 6,500 individuals from the Exome Sequencing Project (ESP as controls to gain statistical power. In addition, among patients with severe RSV bronchiolitis during infancy, we examined genetic associations with asthma, active asthma, persistent wheeze, and bronchial hyperreactivity (methacholine PC20 at age 6 years. We identified four rare nonsynonymous variants that were significantly associated with asthma following severe RSV bronchiolitis, including single variants in ADRB2, FLG and NCAM1 in European Americans (p = 4.6x10-4, 1.9x10-13 and 5.0x10-5, respectively, and NOS1 in African Americans (p = 2.3x10-11. One of the variants was a highly functional nonsynonymous variant in ADRB2 (rs1800888, which was also nominally associated with asthma (p = 0.027 and active asthma (p = 0.013 among European Americans with severe RSV bronchiolitis without including the ESP. Our results suggest that rare nonsynonymous variants contribute to the development of asthma following severe RSV bronchiolitis in infancy, notably in ADRB2. Additional studies are required to explore the role of rare variants in the etiology of asthma and asthma-related traits following severe RSV bronchiolitis.

  15. Anti-IgE therapy with omalizumab for severe asthma: current concepts and potential developments.

    Pelaia, Girolamo; Vatrella, Alessandro; Busceti, Maria Teresa; Gallelli, Luca; Terracciano, Rosa; Maselli, Rosario

    2015-01-01

    The humanized monoclonal anti-IgE antibody omalizumab is currently the only biologic drug approved for asthma treatment. Omalizumab inhibits allergic responses by binding to serum immunoglobulins E (IgE), thus preventing their interactions with cellular IgE receptors. Omalizumab is also capable of down-regulating the expression of high affinity IgE receptors on inflammatory cells, as well as the numbers of eosinophils in both peripheral blood and induced sputum. The clinical effects of omalizumab include relevant improvements in respiratory symptoms and quality of life, paralleled by a marked reduction of asthma exacerbations, emergency room visits, and use of systemic corticosteroids and rescue bronchodilators. Moreover, some recent studies suggest potential benefits of omalizumab also in non allergic phenotypes of severe asthma. Very interesting are also further recent reports referring to the potential inhibitory effect of omalizumab with regard to bronchial structural changes, especially occurring in severe asthma and globally defined as airway remodeling. Omalizumab is relatively well tolerated, and only very rarely induces anaphylactic reactions. Therefore, this drug represents a valid option as add-on therapy for patients with severe persistent asthma, inadequately controlled by high doses of standard inhaled treatments. PMID:25523898

  17. Cardiocirculatory pathophysiological mechanisms in severe acute pancreatitis

    Mónica; García; José; Julián; Calvo

    2010-01-01

    Acute pancreatitis (AP) is a common and potentially lethal acute inflammatory process. Although the majority of patients have a mild episode of AP, 10%-20% develop a severe acute pancreatitis (SAP) and suffer systemic inflammatory response syndrome (SIRS) and/or pancreatic necrosis. The main aim of this article is to review the set of events, f irst localized in the pancreas, that lead to pancreatic inflammation and to the spread to other organs contributing to multiorganic shock. The early pathogenic mechanisms in SAP are not completely understood but both premature activation of enzymes inside the pancreas, related to an impaired cytosolic Ca2+ homeostasis, as well as release of pancreatic enzymes into the bloodstream are considered important events in the onset of pancreatitis disease. Moreover, afferent f ibers within the pancreas release neurotransmitters in response to tissue damage. The vasodilator effects of these neurotransmitters and the activation of pro-inflammatory substances play a crucial role in amplifying the inflammatory response, which leads to systemic manifestation of AP. Damage extension to other organs leads to SIRS, which is usually associated with cardiocirculatoryphysiology impairment and a hypotensive state. Hypotension is a risk factor for death and is associated with a signif icant hyporesponsiveness to vasoconstrictors. This indicates that stabilization of the patient, once this pathological situation has been established, would be a very diff icult task. Therefore, it seems particularly necessary to understand the pathological mechanisms involved in the f irst phases of AP to avoid damage beyond the pancreas. Moreover, efforts must also be directed to identify those patients who are at risk of developing SAP.

    Methacholine bronchial provocation test provides the concentration of methacholine causing a 20% decrease in forced expiratory volume in 1 s (FEV1) from baseline (PC20). The dose-response slope (DRS), and other continuous indices of responsiveness (CIR; the percentage decline from the post-diluent baseline FEV1 after the last dose of methacholine), and per cent recovery index (PRI; the percentage increase from the maximally reduced FEV1 after bronchodilator inhalation) are alternative measures. The clinical relevance of these indices in predicting acute asthma exacerbations has not been fully evaluated.In two prospective cohorts of childhood and elderly asthmatics, baseline PC20, DRS, CIR and PRI were measured and evaluated as predictors of acute asthma exacerbations.We found that PRI was significantly related to the presence of asthma exacerbations during the first year of follow-up in both cohorts of childhood (p=0.025) and elderly asthmatics (p=0.003). In addition, PRI showed a significant association with the total number of steroid bursts during 4.3 years of follow-up in the cohort of childhood asthmatics (p=0.04).We demonstrated that PRI, an index of reversibility following methacholine-induced bronchoconstriction, was a good clinical predictor of acute exacerbations of asthma in both childhood and elderly asthmatics.

  20. Mannose binding lectin (MBL levels predict lung function decline in severe asthma

    Ilonka. H. van Veen

    2006-12-01

    Full Text Available There is increasing evidence that activation of the complement system in asthma contributes to ongoing inflammation, tissue damage and airway remodeling. Mannose binding lectin (MBL is a pattern recognition molecule that serves as the key mediator of the lectin pathway of complement activation. MBL levels are genetically determined and vary widely amongst individuals. In the present study we hypothesized that high MBL levels in asthma are associated with increased loss of lung function over time, as a consequence of inflammatory tissue damage. We measured serum MBL levels by ELISA in 68 patients with severe asthma and prospectively determined the change in post-bronchodilator (pb FEV1 over a mean period of 5.7 years. The relationship between MBL and change in pbFEV1 (FEV1 was analysed using (multiple regression analysis and corrected for possible confounders (age, sex, age of onset, asthma duration, and pbFEV1. The median (range MBL level was 332 (10.8-3587 ng·ml–1. MBL was significantly associated with FEV1 (p<0.04. Patients with a high MBL level (332 ng·ml–1 had an increased risk of lung function decline compared to those with low MBL levels (OR (CI: 3.16 (1.14-8.79, p = 0.027; the excess decline being 42 ml·yr–1 (p = 0.01. We conclude that a high MBL level is associated with an increased decline in lung function in patients with severe asthma. MBL might provide a clue towards better understanding of the pathophysiology of ongoing inflammation and subsequent decline in lung function of patients with severe asthma.

    Full Text Available Context There is controversy concerning the merits of enteral and pa renteral nutrition in the manage ment of patients with severe acute pancreatitis. Objective This study was undertaken to evalua te the effect of enteral nutrition versus parenteral nutrition on serum markers of inflammation and outcome in patients with severe acute pancreatitis. Setting Tertiary care centre in North India. Design A prospective clinical trial. Methods Fifty consecutive patients with severe acute pancreatitis were randomized in a prospective trial to receive total enteral nutrition (n=25 or total parenteral nutrition (n=25. Enteral nutrition was deliver ed distal to the ligament of Treitz. Serum C-reactive protein, transferrin le vels, albumin, surgical intervention, infections, duration of h ospital stay and mortality were compared in the two groups. Results The mean age in the enteral nutrition group was 38.4±13.8 years and in the total parenteral nutrition group 41.1±11.3 years. The etiologi cal factors were alcohol (n=19, gallstones (n=23, idiopathi c (n=7 and drug-induced (n=1. There was a significant decrease in seru m C-reactive protein values in both the enteral nutrition group and the total parenteral nutrition group at one week and two weeks (P<0.001 for both. Serum albumin rose from a prenutritional val ue of 2.82±0.51 g/dL to 3.34±0.45 g/dL on day 14 of nutritional support in the enteral nutrition group (P=0.003; in the total parent eral nutrition group, the level rose from 3.10±0.59 g/dL to 3.21±0.30 g/dL (P=0.638. A signi ficant rise in transferrin value was ob served from day 0 to day 14 in enteral nutrition group (169±30 to 196±36 mg/dL; P<0.001 whereas, in the total parenteral nutrition gr oup, a less significant difference (191±41 to 201±29 mg/dL; P=0.044 was observed.

    Asthma was the most common comorbidity in hospitalized patients during the 2009 influenza pandemic. For unknown reasons, hospitalized asthmatics had less severe outcomes and were less likely to die from pandemic influenza. Our data with primary human bronchial cells indicate that changes intrinsic to epithelial cells in asthma may protect against cytopathology induced by influenza virus. To further study influenza virus pathogenesis in allergic hosts, we aimed to develop and characterize muri...

    1996-01-01

    Patients during a mild to moderate acute attack of asthma (FEV1: 50 - 80% of predicted) were treated with Salmeterol MDI - 50mcg or Rotadisk - 50mcg or Salbutamol (MDI -200mcg). The children were followed by Spirometry, measuring FEV1 (basal) and after treatment: at 30 minutes, 60 minutes and thereafter every 60 minutes until 780 minutes, if the patients maintained the FEV1 above 80% of the predicted value and/or an increment of 20% in the VEF1 basal value. The Salmeterol group showed a significant bronchodilation at 60 minutes which was maintained in half of the patients up to 9 hours. This was not observed in the Salbutamol group: the peak bronchodilatation was observed at 30 minutes and the bronchodilation effect was observed in half of the patients up to 6 hours. There were no significant differences between both presentations of Salmeterol. This drug allowed a prolonged bronchodilator effect and is, according to the several consensus on management of asthma, an adequate option in the treatment of moderate to severe asthma.

    Severe acute respiratory syndrome (SARS) first emerged in Guangdong province,China in November2002.During the following 3 months,it spread rapidly across the world,resulting in approximately 800 deaths.In 2004,subsequent sporadic cases emerged in Singapore and China.A novel coronavims,SARS-CoV,was identified as the etiological agent of SARS.1,2 This virus belongs to a family of large,positive,single-stranded RNA viruses.Nevertheless,genomic characterization shows that the SARS-CoV is only moderately related to other known coronaviruses.3 In contrast with previously described coronaviruses,SARS-CoV infection typically causes severe symptoms related to the lower respiratory tract.The SARS-CoV genome includes 14 putative open reading frames encoding 28 potential proteins,and the functions of many of these proteins are not known.4 A number of complete and partial autopsies of SARS patients have been reported since the first outbreak in 2003.The predominant pathological finding in these cases was diffuse alveolar damage (DAD).This severe pulmonary injury of SARS patients is caused both by direct viral effects and immunopathogenetic factors.5 Many important aspects of the pathogenesis of SARS have not yet been fully clarified.In this article,we summarize the most important mechanisms involved in the complex pathogenesis of SARS,including clinical characters,host and receptors,immune system response and genetic factors.

    Background Fluid therapy for severe acute pancreatitis (SAP) should not only resolve deficiency of blood volume, but also prevent fluid sequestration in acute response stage. Up to date, there has not a strategy for fluid therapy dedicated to SAP. So, this study was aimed to investigate the effects of fluid therapy treatment on prognosis of SAP. Methods Seventy-six patients were admitted prospectively according to the criteria within 72 hours of SAP onset. They were randomly assigned to a rapid fluid expansion group (Group I, n=36) and a controlled fluid expansion group (Group Ⅱ, n=40). Hemodynamic disorders were either quickly (fluid infusion rate was 10-15 ml·kg-1·h-1, Group Ⅰ) or gradually improved (fluid infusion rate was 5-10 ml·kg-1·h-1, Group Ⅱ) through controlling the rate of fluid infusion. Parameters of fluid expansion, blood lactate concentration were obtained when meeting the criteria for fluid expansion. And APACHE Ⅱ scores were obtained serially for 72 hours. Rate of mechanical ventilation, incidence of abdominal compartment syndrome (ACS), sepsis, and survival rate were obtained. Results The two groups had statistically different (P 0.05). Total amount of fluid sequestration within 4 days was higher in Group Ⅰ ((5378±2751)ml) than in Group Ⅱ ((4215±1998)ml, P<0.05). APACHE Ⅱ scores were higher in Group Ⅰ on days 1,2, and 3 (P<0.05). Rate of mechanical ventilation was higher in group Ⅰ (94.4%) than in group Ⅱ (65%, P<0.05). The incidences of abdominal compartment syndrome (ACS) and sepsis were significantly lower in Group Ⅱ (P <0.05). Survival rate was remarkably lower in Group Ⅰ (69.4%) than in Group Ⅱ (90%, P <0.05). Conclusions Controlled fluid resuscitation offers better prognosis in patients with severe volume deficit within 72 hours of SAP onset.

  8. 'Real-life' effectiveness studies of omalizumab in adult patients with severe allergic asthma: systematic review.

    Abraham, I; Alhossan, A; Lee, C S; Kutbi, H; MacDonald, K

    2016-05-01

    We reviewed 24 'real-life' effectiveness studies of omalizumab in the treatment of severe allergic asthma that included 4117 unique patients from 32 countries with significant heterogeneity in patients, clinicians and settings. The evidence underscores the short- and long-term benefit of anti-IgE therapy in terms of the following: improving lung function; achieving asthma control and reducing symptomatology, severe exacerbations and associated work/school days lost; reducing healthcare resource utilizations, in particular hospitalizations, hospital lengths of stay and accident specialist or emergency department visits; reducing or discontinuing other asthma medications; and improving quality of life - thus confirming, complementing and extending evidence from randomized trials. Thus, omalizumab therapy is associated with signal improvements across the full objective and subjective burden of illness chain of severe allergic asthma. Benefits of omalizumab may extend up to 2-4 years, and the majority of omalizumab-treated patients may benefit for many years. Omalizumab has positive short- and long-term safety profiles similar to what is known from randomized clinical trials. Initiated patients should be monitored for treatment response at 16 weeks. Those showing positive response at that time are highly likely to show sustained treatment response and benefit in terms of clinical, quality of life and health resource utilization outcomes.

    2015-12-01

    Full Text Available ABSTRACT OBJECTIVE: To identify, characterize, and quantify associations of various factors with quality of life (QoL in patients with asthma, according to the pharmacotherapy employed. METHODS: This was a cross-sectional study involving 49 patients (≥ 18 years of age with severe uncontrolled or refractory asthma treated at a specialized outpatient clinic of the Brazilian Unified Health Care System, regularly using high doses of inhaled corticosteroids (ICs or other medications, and presenting comorbidities. At a single time point, QoL was assessed with the Asthma Quality of Life Questionnaire (AQLQ. The overall AQLQ score and those of its domains were correlated with demographic variables (gender and age; Asthma Control Questionnaire score; pharmacotherapy (initial IC dose, inhaler devices, and polytherapy; and comorbidities. RESULTS: Better AQLQ scores were associated with asthma control-overall (OR = 0.38; 95% CI: 0.004-0.341; p < 0.001, "symptoms" domain (OR = 0.086; 95% CI: 0.016-0.476; p = 0.001, and "emotional function" domain (OR = 0.086; 95% CI: 0.016-0.476; p = 0.001-and with IC dose ≤ 800 µg-"activity limitation" domain (OR = 0.249; 95% CI: 0.070-0.885; p = 0.029. Worse AQLQ scores were associated with polytherapy-"activity limitation" domain (OR = 3.651; 95% CI: 1.061-12.561; p = 0.036-and number of comorbidities ≤ 5-"environmental stimuli" domain (OR = 5.042; 95% CI: 1.316-19.317; p = 0.015. CONCLUSIONS: Our results, the importance of this issue, and the lack of studies taking pharmacotherapy into consideration warrant longitudinal studies to establish a causal relationship between the identified factors and QoL in asthma patients.

  14. Body composition in severe refractory asthma: comparison with COPD patients and healthy smokers.

    Markos Minas

    Full Text Available BACKGROUND: Body composition is an important parameter for patients with chronic obstructive pulmonary disease (COPD whereas the association between asthma and obesity is not fully understood. The impact of severe refractory asthma (SRA on fat free mass (FFM has not been investigated. METHODOLOGY AND PRINCIPAL FINDINGS: 213 subjects (70 healthy smokers, 71 COPD patients and 72 asthma patients without significant comorbidities were included in the study. In all patients, body composition assessment (using bioelectrical impendance analysis, skinfold and anthropometric measurements and spirometry were performed. Differences in fat free mass index (FFMI between groups were assessed and determinants of FFMI in asthma were evaluated. Patients with SRA had lower values of FFMI compared to patients with mild-to-moderate asthma [18.0(17.3-18.3-19.5(18.4-21.5, p<0.001], despite the fact that they were more obese. The levels of FFMI in SRA were lower than those of GOLD stage I-III COPD and comparable to those of stage IV COPD patients [18.0(17.3-18.3-18.8(17.8-20.1, p = ns]. These differences were present even after proper adjustments for sex, age, smoking status, daily dose of inhaled corticosteroids (ICS and daily use of oral corticosteroids (OCS. In multivariate analysis, independent predictors of FFMI in asthmatic patients were age, use of OCS and the presence of SRA, but not smoking, sex or cumulative dose of ICS used. CONCLUSIONS AND SIGNIFICANCE: SRA is related to the presence of low FFMI that is comparable to that of GOLD stage IV COPD. The impact of this observation on asthma mechanisms and outcomes should be further investigated in large prospective studies.

    prevalence of severe exacerbations and impact of asthma on severe exacerbations, especially in patients with mild-to-moderate COPD.Methods: Patients with mild-to-moderate COPD (≥40 years were extracted from Korean National Health and Nutrition Examination Survey data (2007–2012 and were linked to the national health insurance reimbursement database to obtain medical service utilization records.Results: Of the 2,397 patients with mild-to-moderate COPD, 111 (4.6% had severe exacerbations over the 6 years (0.012/person-year. Severe exacerbations were more frequent in the COPD patients with concomitant self-reported physician-diagnosed asthma compared with only COPD patients (P<0.001. A multiple logistic regression presented that asthma was an independent risk factor of severe exacerbations in patients with mild-to-moderate COPD regardless of adjustment for all possible confounding factors (adjusted odds ratio, 1.67; 95% confidence interval, 1.002–2.77, P=0.049. In addition, age, female, poor lung function, use of inhalers, and low EuroQoL five dimensions questionnaire index values were independently associated with severe exacerbation in patients with mild-to-moderate COPD.Conclusion: In this population-based study, the prevalence of severe exacerbations in patients with mild-to-moderate COPD was relatively low, compared with previous clinical interventional studies. Coexisting asthma significantly impacted the frequency of severe exacerbations in patients with mild-to-moderate COPD, suggesting application of an exacerbation preventive strategy in these patients.

    Bronchial thermoplasty is a young yet promising treatment for severe asthma whose benefit for long-term asthma control outweighs the short-term risk of deterioration and hospitalisation in the days following the treatment. It is an innovative treatment whose clinical efficacy and safety are beginning to be better understood. Since this is a device-based therapy, the overall evaluation of risk-benefit is unlike that of pharmaceutical products; safety aspects, regulatory requirements, study design and effect size assessment may be unfamiliar. The mechanisms of action and optimal patient selection need to be addressed in further rigorous clinical and scientific studies. Bronchial thermoplasty fits in perfectly with the movement to expand personalised medicine in the field of chronic airway disorders. This is a device-based complimentary asthma treatment that must be supported and developed in order to meet the unmet needs of modern severe asthma management. The mechanisms of action and the type of patients that benefit from bronchial thermoplasty are the most important challenges for bronchial thermoplasty in the future. PMID:25445950

  18. Genome Wide Association Study to predict severe asthma exacerbations in children using random forests classifiers

    Litonjua Augusto A

    2011-06-01

    Full Text Available Abstract Background Personalized health-care promises tailored health-care solutions to individual patients based on their genetic background and/or environmental exposure history. To date, disease prediction has been based on a few environmental factors and/or single nucleotide polymorphisms (SNPs, while complex diseases are usually affected by many genetic and environmental factors with each factor contributing a small portion to the outcome. We hypothesized that the use of random forests classifiers to select SNPs would result in an improved predictive model of asthma exacerbations. We tested this hypothesis in a population of childhood asthmatics. Methods In this study, using emergency room visits or hospitalizations as the definition of a severe asthma exacerbation, we first identified a list of top Genome Wide Association Study (GWAS SNPs ranked by Random Forests (RF importance score for the CAMP (Childhood Asthma Management Program population of 127 exacerbation cases and 290 non-exacerbation controls. We predict severe asthma exacerbations using the top 10 to 320 SNPs together with age, sex, pre-bronchodilator FEV1 percentage predicted, and treatment group. Results Testing in an independent set of the CAMP population shows that severe asthma exacerbations can be predicted with an Area Under the Curve (AUC = 0.66 with 160-320 SNPs in comparison to an AUC score of 0.57 with 10 SNPs. Using the clinical traits alone yielded AUC score of 0.54, suggesting the phenotype is affected by genetic as well as environmental factors. Conclusions Our study shows that a random forests algorithm can effectively extract and use the information contained in a small number of samples. Random forests, and other machine learning tools, can be used with GWAS studies to integrate large numbers of predictors simultaneously.

  19. Steroid-induced acute psychosis in a child with asthma: report of one case.

    Lee, K M; Lin, Y Z; Huang, F Y

    2001-01-01

    A 5-year-old girl was admitted due to severe asthmatic attack. She was treated with methylprednisolone (40 mg i.v. q6h), aminophylline (loading with 5 mg/kg and maintained with 0.6 mg/kg/hr i.v. drip), nebulized terbutaline sulphate (5 mg q6h), oral procaterol 12.5 micrograms bid, along with oxygen therapy. Acute psychotic reaction with visual hallucination, delusion, panic reaction and myoclonic movement of hands developed on day 3 of admission. The patient had no previous history of psychiatric problems. The theophylline level was 9.89 micrograms/ml at the moment of psychotic reaction. After the dose of methylprednisolone was reduced from 40 mg to 20 mg i.v. q6h and shifted to other anti-asthma treatment by procaterol metered dose inhaler via spacer, the psychotic reaction disappeared a few hours later. The psychotic reaction was thought to be due to steroid therapy since no other causes could explain the psychotic reaction. PMID:11431864

    Background: Reducing exposure to household dust inhalant allergens has been proposed as one strategy to reduce asthma. Objective: To examine the dose-response relationships and health impact of five common household dust allergens on disease severity, quantified using both symptom frequency and medication use, in atopic and non-atopic asthmatic children. Methods: Asthmatic children (N=300) aged 4-12 years were followed for 1 year. Household dust samples from two indoor locations were analyzed for allergens including dust mite (Der p 1, Der f 1), cat (Fel d 1), dog (Can f 1), cockroach (Bla g 1). Daily symptoms and medication use were collected in monthly telephone interviews. Annual disease severity was examined in models including allergens, specific IgE sensitivity and adjusted for age, gender, atopy, ethnicity, and mother's education. Results: Der p 1 house dust mite allergen concentration of 2.0 {mu}g/g or more from the main room and the child's bed was related to increased asthma severity independent of allergic status (respectively, OR 2.93, 95% CI 1.37, 6.30 for 2.0-10.0 {mu}g/g and OR 2.55 95% CI 1.13, 5.73 for {>=}10.0 {mu}g/g). Higher pet allergen levels were associated with greater asthma severity, but only for those sensitized (cat OR 2.41 95% CI 1.19, 4.89; dog OR 2.06 95% CI 1.01, 4.22). Conclusion: Higher levels of Der p 1 and pet allergens were associated with asthma severity, but Der p 1 remained an independent risk factor after accounting for pet allergens and regardless of Der p 1 specific IgE status.

Objective: To examine the dose-response relationships and health impact of five common household dust allergens on disease severity, quantified using both symptom frequency and medication use, in atopic and non-atopic asthmatic children. Methods: Asthmatic children (N=300) aged 4-12 years were followed for 1 year. Household dust samples from two indoor locations were analyzed for allergens including dust mite (Der p 1, Der f 1), cat (Fel d 1), dog (Can f 1), cockroach (Bla g 1). Daily symptoms and medication use were collected in monthly telephone interviews. Annual disease severity was examined in models including allergens, specific IgE sensitivity and adjusted for age, gender, atopy, ethnicity, and mother's education. Results: Der p 1 house dust mite allergen concentration of 2.0 μg/g or more from the main room and the child's bed was related to increased asthma severity independent of allergic status (respectively, OR 2.93, 95% CI 1.37, 6.30 for 2.0-10.0 μg/g and OR 2.55 95% CI 1.13, 5.73 for ≥10.0 μg/g). Higher pet allergen levels were associated with greater asthma severity, but only for those sensitized (cat OR 2.41 95% CI 1.19, 4.89; dog OR 2.06 95% CI 1.01, 4.22). Conclusion: Higher levels of Der p 1 and pet allergens were associated with asthma severity, but Der p 1 remained an independent risk factor after accounting for pet allergens and regardless of Der p 1 specific IgE status.

    Different genes are associated with categorical classifications of asthma severity. However, continuous outcomes should be used to catch the heterogeneity of asthma phenotypes and to increase the power in association studies. Accordingly, the aim of this study was to evaluate the association between single nucleotide polymorphisms (SNPs) in candidate gene regions and continuous measures of asthma severity, in adult patients from the general population. In the Gene Environment Interactions in Respiratory Diseases (GEIRD) study (www.geird.org), 326 subjects (aged 20-64) with ever asthma were identified from the general population in Verona (Italy) between 2007 and 2010. A panel of 236 SNPs tagging 51 candidate gene regions (including one or more genes) was analysed. A symptom and treatment score (STS) and pre-bronchodilator FEV1% predicted were used as continuous measures of asthma severity. The association of each SNP with STS and FEV1% predicted was tested by fitting quasi-gamma and linear regression models, respectively, with gender, body mass index and smoking habits as potential confounders. The Simes multiple-test procedure was used for controlling the false discovery rate (FDR). SNP rs848 in the IL13 gene region (IL5/RAD50/IL13/IL4) was associated with STS (TG/GG vs TT genotype: uncorrected p-value = 0.00006, FDR-corrected p-value = 0.04), whereas rs20541 in the same gene region, in linkage disequilibrium with rs848 (r2 = 0.94) in our sample, did not reach the statistical significance after adjusting for multiple testing (TC/CC vs TT: uncorrected p-value = 0.0003, FDR-corrected p-value = 0.09). Polymorphisms in other gene regions showed a non-significant moderate association with STS (IL12B, TNS1) or lung function (SERPINE2, GATA3, IL5, NPNT, FAM13A) only. After adjusting for multiple testing and potential confounders, SNP rs848 in the IL13 gene region is significantly associated with a continuous measure of symptom severity in adult subjects with ever asthma

    Full Text Available Conducting a comprehensive clinical and paraclinical examinations of 53 children with severe asthma made it possible to establish the relative increase in the content of CD 22-lymphocytes (relative risk – 2.1 odds ratio - 3.8 and interleukin-5 (relative risk – 1.8 odds ratio - 3.4 in the serum of the patients with fast acetylatic status that reflected the implementation of the respiratory tract eosinophilic inflammation. In children with a slow acetylation phenotype severe asthma probably has been formed with the participation of other mechanisms that reflected the correlation of IL-8 with increased functional activity of blood neutrophils according to NBT-test (r = 0,5; p <0, 05 and bronchial hyperresponsiveness (r = 0,9; p <0,05.

    2002-01-01

    One out of ten cases of acute pancreatitis develops into severe acute pancreatitis which is a life threatening disorder with a high mortality rate. The other nine cases are self limiting and need very little therapy. The specificity of good clinical judgement on admission, concerning the prognosis of the attack, is high (high specificity) but misses a lot of severe cases (low sensitivity). The prediction of severity in acute pancreatitis was first suggested by John HC Ranson in 1974. Much eff...

    2016-01-01

    Background: It is well established that short-term exposure to ambient air pollutants can exacerbate asthma, the role of early life or long-term exposure is less clear. We assessed the association between severe asthma exacerbations with both birth and annual exposure to outdoor air pollutants with a population-based cohort of asthmatic children in the province of Quebec (Canada). Method: Exacerbations of asthma occurring between 1 April 1996 and 31 March 2011 were defined as one hospitalization or emergency room visit with a diagnosis of asthma for children (<13 years old) already diagnosed with asthma. Annual daily average concentrations of ozone (O3) and nitrogen dioxide (NO2) were estimated at the child’s residential postal code. Satellite based levels of fine particulate (PM2.5) estimated for a grid of 10 km by 10 km were also assigned to postal codes of residence for the whole province. Hazard ratios (HRs) were estimated from Cox models with a gap time approach for both birth and time-dependant exposure. Results: Of the 162,752 asthmatic children followed (1,020,280 person-years), 35,229 had at least one asthma exacerbation. The HRs stratified by age groups and adjusted for the year of birth, the ordinal number of exacerbations, sex, as well as material and social deprivation, showed an interquartile range increase in the time-dependant exposure to NO2 (4.95 ppb), O3 (3.85 ppb), and PM2.5 (1.82 μg/m3) of 1.095 (95% CI 1.058–1.131), 1.052 (95% CI 1.037–1.066) and 1.025 (95% CI 1.017–1.031), respectively. While a positive association was found to PM2.5, no associations were found between exposure at birth to NO2 or O3. Conclusions: Our results support the conclusion, within the limitation of this study, that asthma exacerbations in asthmatic children are mainly associated with time dependent residential exposures less with exposure at birth.

    Full Text Available Abstract Background The heat shock proteins (Hsps are induced by stresses such as allergic factors and inflammatory responses in bronchi epithelial cells and therefore may be detectable in patients with asthma. However, the etiologic link between anti-Hsps and asthma (its severity and related inflammatory responses such as interleukin-4 and immunoglobulin E has not been established. We determined whether antibodies against Hsp60 and Hsp70 were present in patients with asthma and evaluated their associations with risk and severity of asthma. Methods We determined the levels of anti-Hsp60 and anti-Hsp70 by immunoblot and their associations with risk and symptom severity of asthma in 95 patients with asthma and 99 matched non-symptomatic controls using multivariate logistic regression analysis. Results Compared to the controls, asthma patients were more likely to have detectable anti-Hsp60 (17.2% vs 5.1% and anti-Hsp70 (33.7% vs 8.1% (p ≤ 0.001. In particular, the presence of anti-Hsp70 was associated with a greater than 2 fold risk for asthma (adjusted OR = 2.21; 95% CI = 1.35~3.59. Furthermore, both anti-Hsp60 and anti-Hsp70 levels were positively correlated with symptom severity (p Conclusions These data suggest that anti-Hsp60 and especially anti-Hsp70 correlate with the attacks and severity of asthma. The underlying molecular mechanisms linking antibodies to heat shock proteins and asthma remain to be investigated.

    Airway epithelial injury is the hallmark of various respiratory diseases, but its mechanisms remain poorly understood. While 13-S-hydroxyoctadecadienoic acid (13-S-HODE) is produced in high concentration during mitochondrial degradation in reticulocytes little is known about its role in asthma pathogenesis. Here, we show that extracellular 13-S-HODE induces mitochondrial dysfunction and airway epithelial apoptosis. This is associated with features of severe airway obstruction, lung remodeling...

    Systems biology provides opportunities to fully understand the genes and pathways in disease pathogenesis. We used literature knowledge and unbiased multiple data meta-analysis paradigms to analyze microarray datasets across different mouse strains and acute allergic asthma models. Our combined gene-driven and pathway-driven strategies generated a stringent signature list totaling 933 genes with 41% (440) asthma-annotated genes and 59% (493) ignorome genes, not previously associated with asthma. Within the list, we identified inflammation, circadian rhythm, lung-specific insult response, stem cell proliferation domains, hubs, peripheral genes, and super-connectors that link the biological domains (Il6, Il1ß, Cd4, Cd44, Stat1, Traf6, Rela, Cadm1, Nr3c1, Prkcd, Vwf, Erbb2). In conclusion, this novel bioinformatics approach will be a powerful strategy for clinical and across species data analysis that allows for the validation of experimental models and might lead to the discovery of novel mechanistic insights in asthma.

    Full Text Available Ji Young Kang, Sook Young Lee, Chin Kook Rhee, Seung Joon Kim, Soon Seog Kwon, Young Kyoon KimDepartment of Internal Medicine, College of Medicine, Catholic University of Korea, Seoul, KoreaBackground and objectives: The influence of aging on the development of asthma has not been studied thoroughly. The aim of this study was to investigate age-related airway responses involving lung histology and expression of muscarinic receptors in a murine model of acute asthma. Methods: Female BALB/c mice at the ages of 6 weeks and 6, 9, and 12 months were sensitized and challenged with ovalbumin (OVA for 1 month (n = 8–12 per group. We analyzed inflammatory cells and T-helper (Th2 cytokines in bronchoalveolar lavage (BAL fluid and parameters of airway remodeling and expression of muscarinic receptors in lung tissue. Results: Among the OVA groups, total cell and eosinophil numbers in BAL fluid were significantly higher in the older (6-, 9-, and 12-month-old mice than in the young (6-week-old mice. Interleukin (IL 4 (IL-4 concentration increased, but IL-5 and IL-13 concentrations showed a decreased tendency, with age. IL-17 concentration tended to increase with age, which did not reach statistical significance. periodic acid-Schiff (PAS staining area, peribronchial collagen deposition, and area of α-smooth muscle staining were significantly higher in the 6-month older OVA group than in the young OVA group. The expression of the M3 and M2 muscarinic receptors tended to increase and decrease, respectively, with age. Conclusion: The aged mice showed an active and unique pattern not only on airway inflammation, but also on airway remodeling and expression of the muscarinic receptors during the development of acute asthma compared with the young mice. These findings suggest that the aging process affects the pathogenesis of acute asthma and age-specific approach might be more appropriate for better asthma control in a clinical practice.Keywords: aging, asthma

  13. Near-fatal asthma in the elderly.

    Arjona, Nydia

    2015-01-01

    Asthma affects the elderly as often as other age groups; however, it more often becomes fatal in the elderly. Unfortunately, asthma is often unmanaged or underdiagnosed in the older population. It is important for health care providers to recognize risk factors in the elderly and properly treat them before asthma becomes fatal. This article describes near-fatal asthma and identifies risk factors specifically for the elderly. Symptoms of asthma are reviewed as well as assessments and diagnostic tests to identify asthma severity and complications. Proper management needs to be urgently initiated to prevent worsening respiratory distress; this includes fast-acting drug treatments appropriate for elderly patients. Decompensated acute respiratory failure, secondary to severe asthma, requires the skills of an experienced anesthesiologist because these patients may rapidly deteriorate during induction and intubation. Ventilator management must include strategies to prevent worsening hyperinflation of the lungs. Elderly asthma patients have a higher mortality risk related to ventilator complications and other comorbidities. PMID:25470264

  14. Japanese Guideline for Adult Asthma 2014

    Ken Ohta

    2014-01-01

    Full Text Available Adult bronchial asthma (hereinafter, asthma is characterized by chronic airway inflammation, reversible airway narrowing, and airway hyperresponsiveness. Long-standing asthma induces airway remodeling to cause intractable asthma. The number of patients with asthma has increased, and that of patients who die from asthma has decreased (1.5 per 100,000 patients in 2012. The aim of asthma treatment is to enable patients with asthma to lead a normal life without any symptoms. A good relationship between physicians and patients is indispensable for appropriate treatment. Long-term management with antiasthmatic agents and elimination of the causes and risk factors of asthma are fundamental to its treatment. Four steps in pharmacotherapy differentiate between mild and intensive treatments; each step includes an appropriate daily dose of an inhaled corticosteroid, varying from low to high. Long-acting 02-agonists, leukotriene receptor antagonists, and sustained-release theophylline are recommended as concomitant drugs, while anti-immunoglobulin E antibody therapy has been recently developed for the most severe and persistent asthma involving allergic reactions. Inhaled 02-agonists, aminophylline, corticosteroids, adrenaline, oxygen therapy, and others are used as needed in acute exacerbations by choosing treatment steps for asthma exacerbations depending on the severity of attacks. Allergic rhinitis, chronic obstructive pulmonary disease, aspirin-induced asthma, pregnancy, asthma in athletes, and coughvariant asthma are also important issues that need to be considered.

Besides the acute symptoms, asthma is characterized by persistent airway inflammation and airway wall remodeling....

  16. ROLE OF ORAL MONTELUKAST IN ACUTE ASTHMA EXACERBATIONS : A RANDOMIZED PLACEBO CONTROLLED TRIAL

    Gaude

    2015-08-01

    Full Text Available BACKGROUND: Leukotriene receptor antagonists (LTRAs are well established in the management of outpatient asthma. However, there is very little information as to their role in acute asthma exacerbations. The present study was done to evaluate the clinical efficacy of oral Montelukast as an add on therapy to the usual standard therapy of acute attack of bronchial asthma. MATERIALS AND METHODS: A randomized single blinded controlled study was conducted in a tertiary car e teaching hospital. A total of 320 patients with age >18 years of acute exacerbations due to bronchial asthma were included in the study. The patients were randomized into two study and control groups. The study group patients received oral Montelukast (1 0mg once daily for 2 weeks, while the control group received a placebo. All the patients received standard therapy according to GINA guidelines. Improvements in lung function tests, clinical symptoms and relapse rates were monitored at baseline, at discha rge and at 2 weeks. Side effects profile was also monitored. RESULTS: A total of 255 patients were finally assessed. One hundred thirty patients belonged to study group and 125 in the control group. Baseline characteristics were similar and well matched in both the groups. Mean age was 39.9±15.8 years in study group and 42.8±12.8 in the control group and majority were female patients in both the groups. At the end of 2 weeks, it was observed that there were no significant improvements in FEV 1 and FVC as com pared to the control group. However, there was significant improvement in PEFR at 2 weeks (0.4 L/sec, 12% as compared to the control group (p <0.0376. Length of hospital stay was similar in both the groups. No serious adverse effects were noted during th e course of the study. CONCLUSIONS: In acute asthma exacerbations, the present study showed that additional administration of oral Montelukast resulted in significantly higher PEFR at 2 weeks as compared to the standard

    We investigated the short-term effects of particulate matter with aerodynamic diameter ozone (O(3)) on pediatric asthma emergency admissions in Athens, Greece over the period 2001-2004. We explored effect modification patterns by season, sex, age and by the presence of desert dust transported mainly from the Sahara area. We used daily time-series data provided by the children's hospitals and the fixed monitoring stations. The associations were investigated using Poisson regression models controlling for seasonality, weather, influenza episodes, day of the week and holiday effects. A 10 μg/m(3) increase in PM(10) was associated with a 2.54% increase (95% confidence interval (CI): 0.06%, 5.08%) in the number of pediatric asthma hospital admissions, while the same increase in SO(2) was associated with a 5.98% (95% CI: 0.88%, 11.33%) increase. O(3) was associated with a statistically significant increase in asthma admissions among older children in the summer. Our findings provide limited evidence of an association between NO(2) exposure and asthma exacerbation. Statistically significant PM(10) effects were higher during winter and during desert dust days, while SO(2) effects occurred mainly during spring. Our study confirms previously reported PM(10) effects on emergency hospital admissions for pediatric asthma and further provides evidence of stronger effects during desert dust days. We additionally report severe effects of SO(2), even at today's low concentration levels. PMID:21296347

  18. Efficacy and safety of reslizumab in patients with moderate to severe eosinophilic asthma.

    Lim, Hui Fang; Nair, Parameswaran

    2015-04-01

    Reslizumab, a neutralizing anti-IL-5 monoclonal antibody, is a promising adjunctive treatment for severe eosinophilic asthma. Monthly intravenous 3.0 mg/kg reslizumab had resulted in improvements in lung function and asthma control. It is well tolerated and common adverse events include headache, nasopharyngitis and upper respiratory tract infection. Rebound eosinophilia after cessation of reslizumab and attenuation of the treatment response with repeated dosing had been reported. Stringent selection of patients with a high eosinophil burden, who are poorly controlled despite moderate to high doses of inhaled corticosteroid, confers the most significant treatment response. Future trials should compare the dose, delivery platform, frequency of dosing and study combinations with other biologics, which will affect its maximal clinical efficacy. PMID:25578680

  20. Electronic Nose Breathprints Are Independent of Acute Changes in Airway Caliber in Asthma

    Jan van der Maten

    2010-10-01

    Full Text Available Molecular profiling of exhaled volatile organic compounds (VOC by electronic nose technology provides breathprints that discriminate between patients with different inflammatory airway diseases, such as asthma and COPD. However, it is unknown whether this is determined by differences in airway caliber. We hypothesized that breathprints obtained by electronic nose are independent of acute changes in airway caliber in asthma. Ten patients with stable asthma underwent methacholine provocation (Visit 1 and sham challenge with isotonic saline (Visit 2. At Visit 1, exhaled air was repetitively collected pre-challenge, after reaching the provocative concentration (PC20 causing 20% fall in forced expiratory volume in 1 second (FEV1 and after subsequent salbutamol inhalation. At Visit 2, breath was collected pre-challenge, post-saline and post-salbutamol. At each occasion, an expiratory vital capacity was collected after 5 min of tidal breathing through an inspiratory VOC-filter in a Tedlar bag and sampled by electronic nose (Cyranose 320. Breathprints were analyzed with principal component analysis and individual factors were compared with mixed model analysis followed by pairwise comparisons. Inhalation of methacholine led to a 30.8 ± 3.3% fall in FEV1 and was followed by a significant change in breathprint (p = 0.04. Saline inhalation did not induce a significant change in FEV1, but altered the breathprint (p = 0.01. However, the breathprint obtained after the methacholine provocation was not significantly different from that after saline challenge (p = 0.27. The molecular profile of exhaled air in patients with asthma is altered by nebulized aerosols, but is not affected by acute changes in airway caliber. Our data demonstrate that breathprints by electronic nose are not confounded by the level of airway obstruction.

    The aim of the present study was to describe the prevalence and severity of asthma in young Danish adults over three decades. Males and females aged 20-35 yrs were sampled from the population of Copenhagen for the three surveys (1976-1978, 1991-1993 and 2001-2004). A total of 3,285 (46% male......) subjects answered a questionnaire, and had their height, weight, forced expiratory volume in 1 s (FEV1) and forced vital capacity measured. The prevalence of self-reported asthma was 1.5, 4.7 and 6.9%, respectively, in the three surveys (p<0.001). An increasing prevalence of asthma was observed in both...... males and females, although it was highest among females. The difference in FEV1 between asthmatic and nonasthmatic subjects gradually increased, being 2.3 (p = 0.56) and 14.2% of the predicted value (p<0.001), respectively, in 1976-1978 and 2001-2004.

    2010-05-01

    Full Text Available Abstract Background Diverse environmental exposures, studied separately, have been linked to health outcomes in adult asthma, but integrated multi-factorial effects have not been modeled. We sought to evaluate the contribution of combined social and physical environmental exposures to adult asthma lung function and disease severity. Methods Data on 176 subjects with asthma and/or rhinitis were collected via telephone interviews for sociodemographic factors and asthma severity (scored on a 0-28 point range. Dust, indoor air quality, antigen-specific IgE antibodies, and lung function (percent predicted FEV1 were assessed through home visits. Neighborhood socioeconomic status, proximity to traffic, land use, and ambient air quality data were linked to the individual-level data via residential geocoding. Multiple linear regression separately tested the explanatory power of five groups of environmental factors for the outcomes, percent predicted FEV1 and asthma severity. Final models retained all variables statistically associated (p Results Mean FEV1 was 85.0 ± 18.6%; mean asthma severity score was 6.9 ± 5.6. Of 29 variables screened, 13 were retained in the final model of FEV1 (R2 = 0.30; p 2 = 0.16; p 1 as an independent variable to the severity model further increased its explanatory power (R2 = 0.25. Conclusions Multivariate models covering a range of individual and environmental factors explained nearly a third of FEV1 variability and, taking into account lung function, one quarter of variability in asthma severity. These data support an integrated approach to modeling adult asthma outcomes, including both the physical and the social environment.

Thirty patients of acute attack of bronchial asthma were randomized into three groups: MgSO4 nebulization (group A, salbutamol nebulization (group B, and their combination (group C. All patients were monitored before and after nebulization (each 20 minutes for peak expiratory flow rate (PEFR, respiratory rate (RR, heart rate (HR, blood pressure, pulsus paradoxus, oxygen saturation, clinical examination, and Fischl index.Results: A highly significant improvement in PEFR, PEFR percentage, and Fischl index and significant decrease in RR and HR was observed in all groups. A similar improvement in PEFR was observed in group A and group B (P=0.389. The difference in peak expiratory flow (PEF improvement was insignificant between group B and group C (P=0.101, while there was a significant differ­ence between group A and group C (P=0.014 in favor of group C.Conclusion: Nebulized MgSO4 alone or combined with salbutamol has a clinically significant bronchodilator effect in acute asthma and leads to clinical improvement, increase in PEFR, reduction in HR, and reduction in RR. The response to nebulized MgSO4 alone (PEFR improvement 54±35.6 L/min, P=0.001 is comparable (P=0.389 to that of nebulized salbutamol (PEFR improvement 67.0±41.9 L/min, P=0.001 and is significantly less than (P=0.014 that of nebulized combination (PEFR improvement 92.0±26.9 L/min, P=0.000.

    2012-04-01

    Full Text Available Oxidative stress mediated by reactive oxygen species is known to contribute to the inflammatory process of bronchial asthma. Reactive oxygen species are released into the bronchial tree by activated inflammatory cells. In this study, we aimed to determine the effect of vitamin C administration on leukocyte vitamin C level as well as severity of asthma. In this double blind clinical trial study we evaluated 60 patients with chronic stable asthma. The patients were divided into two groups (A and B including 30 patients in each group. Patients in these groups were matched according to their age, weight, height, gender, BMI and drug consumption. In addition to standard asthma treatment (according to stepwise therapy in 4th step of bronchial asthma in which the patients were controlled appropriately, group A received 1000 mg vitamin C daily and group B received placebo. At the baseline and after one month treatment, non-fasting blood samples were drawn for laboratory evaluations. Asthmatic patient's clinical condition was evaluated through standard pulmonary function test (PFT. The mean (±SD leukocyte vitamin C level in group A at the baseline and after one month treatment with 1000 mg/day vitamin C, were 0.0903 (±0.0787 µg/108 leukocytes and 0.1400 (±0.0953 µg/108 leukocytes respectively (P<0.05. The mean (±SD leukocyte vitamin C level in group B at the baseline and after one month administration of placebo, were 0.0867 (±0.0629 µg/108 leukocytes and 0.0805(±0.0736 µg/108 leukocytes respectively. The leukocyte vitamin C level in group A was higher than those of group B after one month treatment with vitamin C and placebo and the difference was statistically significant (P<0.05. Comparing PFT (FEV1, FVC and FEV1/FVC in group B during the study period showed a significant increase in FEV1 (P<0.05, while the other two parameters remained unchanged. In group A, who received 1000 mg/day vitamin C, none of the spirometry parameters changed after

    2005-09-01

    Full Text Available Abstract Background Asthma is a growing problem in the Caribbean but the prevalence in most islands is unknown and possible inter-island variation in prevalence has not been determined. A nationwide cross-sectional survey was conducted to compare the prevalence of asthma symptoms among high school students in the two islands of the Republic of Trinidad and Tobago. Methods Questionnaire and video instruments based on those developed by the International Study of Asthma & Allergy in Childhood (ISAAC were used to assess asthma prevalence among 6394 children (age range, 11–19 years; mean age, 14.08 yrs in the second and third years of 35 randomly selected high schools in Trinidad and Tobago. This cross sectional survey was conducted between September and December 2002. Results A total of 4988 questionnaires were available for analysis (3519 in Trinidad and 1469 in Tobago. Among respondents from the two islands, there were no significant differences in the prevalence of ever wheezing (24.1% and 24.3% for Trinidad and Tobago, respectively, RR 0.99, 95% CI, 0.90–1.08; wheezing in the previous 12 months (13.1% & 13.4%, RR 0.98, 95% CI 0.84–1.15; a previous or current diagnosis of asthma (12.8% & 13.5%, RR 0.95, 95% CI 0.82–1.12 and night cough in the past 12 months (35.4% & 38.3%, RR0.93, 95% CI 0.86–1.00. However, symptoms of severe asthma were significantly more common among students from Tobago and included having had more than one acute attack in the past year (13.4% & 15.8%, RR 0.85, 95% CI 0.73–1.00, p = 0.0004, night waking as a result of wheeze (7.4% & 10.9%, RR 0.68, 95% CI 0.56–0.83, p Conclusion Self-reported wheeze is common among adolescents in Trinidad and Tobago. Variation in symptoms was found between the two territories; high school students from Tobago, the less industrialized of the two islands, reported more symptoms of severe asthma and exercise-induced wheeze.

  12. Role of serum eosinophil cationic protein as a biological marker to assess the severity of bronchial asthma

    Objective: The study was carried out to evaluate the role of serum eosinophil cationic protein (ECP) as a biological marker for the diagnosis and to assess the severity of bronchial asthma. Methodology: This observational cross-sectional study was conducted among 70 bronchial asthma patients and 45 disease controls (tuberculosis-15, chronic obstructive pulmonary disease-15, interstitial lung disease-15) enrolled from patients attending the outpatient department of the National Institute of Disease of the Chest and Hospital (NIDCH), Dhaka, Bangladesh during July 2010 to June 2011. Global Initiative of Asthma Management and Prevention (GINA) criteria were followed for selection of both atopic and non-atopic patients with intermittent or persistent (mild, moderate and severe) asthma. Serum level of eosinophil cationic protein (ECP), IgE, forced expiratory volume in 1 second (FEV 1% predicted) and circulatory eosinophil (CE) count were estimated. Results: Mean serum ECP level (28.8 +- 42.9 vs. 6.82 +- 3.5 ng/mL; P<0.001), IgE level (383.59 - 225.3 vs. 135 +- 131.8 IU/mL; P<0.001) and percent circulatory eosinophil count (9.95 +- 3.7 vs. 5.95 +- 1.4; P<0.024) were all found significantly raised among asthma patients than disease controls but % FEV1 was equivocal. All grades of persistent asthma patients had significantly (P<0.025 and P<0.002) higher mean ECP level than intermittent cases but serum IgE level and CE count did not differ significantly. FEV1 % predicted correlated well among moderate and severe persistent asthma but was equivocal for intermittent and mild persistent cases. Conclusion: This study has reinforced that serum eosinophil cationic protein is a dependable biological marker with more discriminatory power over other indicators for bronchial asthma and to assess its severity.

    1999-07-01

    The aim of this study was to evaluate whether ozone exposure induces a similar airway inflammatory response in subjects with different degrees of asthma severity. Two groups of asthmatic subjects were studied: seven with intermittent mild asthma not requiring regular treatment (group A); and seven with persistent mild asthma requiring regular treatment with inhaled corticosteroids and long-acting {beta}{sub 2}-agonists (group B). All subjects were exposed, in a randomized cross-over design, to air or O{sub 3} (0.26 parts per million (ppm) for 2 h with intermittent exercise); subjects in group B withdrew from regular treatment 72 h before each exposure. Before the exposure, and 1 and 2 h after the beginning of the exposure they performed a pulmonary function test, and a questionnaire was completed to obtain a total symptom score (TSS). Six hours after the end of the exposure, hypertonic saline (HS) sputum induction was conducted. Sputum cell percentages, eosinophil cationic protein (ECP) and interleukin (IL)-8 concentrations in the sputum supernatant were measured. TSS significantly increased and forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) significantly decreased after O{sub 3} exposure in comparison with air exposure in group A, whereas no changes were observed in group B except for a significant decrement of FEV1 2 h after the beginning of O{sub 3} exposure. Sputum neutrophil percentage was significantly higher after O{sub 3} exposure than after air exposure in both groups (Group A: 70.2% (28-87) versus 26.6% (8.6-73.2); Group B: 62.1% (25-82.4) versus 27.9% (14.4-54)). IL-8 was higher in sputum supernatant collected 6 h after O{sub 3} exposure than after air, only in group A. No change due to O{sub 3} has been found in sputum eosinophil percentage and ECP concentration in both groups. In conclusion, the degree of airway response to a short-term exposure to ozone is different in subjects with asthma of different severity. The

    1995-01-01

    Forty seven children (6-14 years), with an acute mild or moderate attack of asthma (clinical score 3 or FEV1 > 50% of the predicted), were treated with terbutaline sulphate, by inhalation route with a dry powder inhaler (Turbuhaler - 0,5 mg - group T; N=27, or by a nebulizer 1% solution-in saline-compressed air (6 l/min.) group S; N=20. The children were evaluated at 5, 15, 25 and 30 minutes after the initial treatment. In both groups a significant fall of the clinical score (starting at 15 minutes) (p 0.05). At the end of the first treatment, the number of patients with a FEV(1) < 80% was similar in both groups (T = 13/27 and S = 10/20). The same treatment was repeated, and all the children showed a marked improvement, except for one boy of the group T was hospitalized. In conclusion, children with mild or moderate acute attacks of asthma can be treated up to a week with an inhalation of dry powder, resulting in adequate bronchodilatation without important side effects.

  15. Evaluation of severity by whole body CT in acute pancreatitis

    Evaluation of severity in acute pancreatitis is still controversial. We studied about thirteen cases of acute pancreatitis and calculated CT score using findings of early whole body CT scanning within forty eight hours after initial symptoms. Simultaneously we calculated clinical score too. CT score was constituted by ten points (changes limitted in pancreas itself, extension of inflammation and extrapancreatic fluid collection etc.). And clinical score was constituted by eight clinical symptoms and fourteen laboratory findings in fatal pancreatitis reported in Japan. From these studies, we conclude that early CT scanning is more useful for objective determination of severity and therapy (surgical or medical) in acute pancreatitis than clinical findings. So we made new classification of severity in acute pancreatitis by CT score as follows: severe (6=: medical therapy). (author)

  18. Anti-IgE treatment, airway inflammation and remodelling in severe allergic asthma: current knowledge and future perspectives

    Konstantinos Samitas

    2015-12-01

    Full Text Available Asthma is a disorder of the airways involving various inflammatory cells and mediators and characterised by bronchial hyperresponsiveness, chronic inflammation and structural alterations in the airways, also known as remodelling. IgE is an important mediator of allergic reactions and has a central role in allergic asthma pathophysiology, as it is implicated in both the early and late phase allergic response. Moreover, clinical and mechanistic evidence has lately emerged, implicating IgE in the development of airway remodelling. The use of monoclonal antibodies targeting IgE, such as omalizumab, has proven very effective in improving respiratory symptoms and quality of life, while reducing asthma exacerbations, emergency room visits and the use of systemic corticosteroids in allergic severe asthma. These effects are believed to be mainly mediated by omalizumab's inhibitory effect on the initiation and further propagation of the allergic inflammation cascade. However, there is evidence to suggest that anti-IgE treatment remains effective long after it has been discontinued. In part, these findings could be attributed to the possible ameliorating effects of anti-IgE treatment on airway remodelling. In this review, we discuss recent findings supporting the notion that anti-IgE treatment modulates the complex immune responses that manifest clinically as asthma and ameliorates airway remodelling changes often observed in allergic severe asthma phenotypes.

  20. Severe acute pancreatitis and non occlusive mesenteric ischemia

    The mechanism and pathology of patients with severe acute pancreatitis with non-occlusive mesenteric ischemia (NOMI) are still unclear. Currently, there are some reports that vasoconstriction associated factors (angiopoietin-2, endothelin-1 and VEGF et al.) have important role in the development of NOMI with severe acute pancreatitis. In our experience, one of characteristic pathological findings of NOMI is the non-consecutive enterointestinal damage. The diagnosis of NOMI is not easy in the early stage, so we attempt to use hepatic perfusion CT to diagnose it. Hepatic perfusion CT can evaluate hepatic portal flow (HPF) and hepatic arterial flow (HAF), separately. In our study, HPF of acute pancreatitis patients with NOMI was significantly slower than those without NOMI. Therefore, evaluation of hepatic perfusion in the early stage might be extremely helpful in the diagnosis of NOMI. In this paper, we would like to report the mechanism, pathology, diagnosis and treatment of NOMI in severe acute pancreatitis. (author)

  1. Surfactant protein B polymorphisms are associated with severe respiratory syncytial virus infection, but not with asthma

    Heinzmann Andrea

    2007-05-01

    Full Text Available Abstract Background Surfactant proteins (SP are important for the innate host defence and essential for a physiological lung function. Several linkage and association studies have investigated the genes coding for different surfactant proteins in the context of pulmonary diseases such as chronic obstructive pulmonary disease or respiratory distress syndrome of preterm infants. In this study we tested whether SP-B was in association with two further pulmonary diseases in children, i. e. severe infections caused by respiratory syncytial virus and bronchial asthma. Methods We chose to study five polymorphisms in SP-B: rs2077079 in the promoter region; rs1130866 leading to the amino acid exchange T131I; rs2040349 in intron 8; rs3024801 leading to L176F and rs3024809 resulting in R272H. Statistical analyses made use of the Armitage's trend test for single polymorphisms and FAMHAP and FASTEHPLUS for haplotype analyses. Results The polymorphisms rs3024801 and rs3024809 were not present in our study populations. The three other polymorphisms were common and in tight linkage disequilibrium with each other. They did not show association with bronchial asthma or severe RSV infection in the analyses of single polymorphisms. However, haplotypes analyses revealed association of SP-B with severe RSV infection (p = 0.034. Conclusion Thus our results indicate a possible involvement of SP-B in the genetic predisposition to severe RSV infections in the German population. In order to determine which of the three polymorphisms constituting the haplotypes is responsible for the association, further case control studies on large populations are necessary. Furthermore, functional analysis need to be conducted.

  2. Comorbidities in severe asthma: frequency of rhinitis, nasal polyposis, gastroesophageal reflux disease, vocal cord dysfunction and bronchiectasis

    2009-01-01

    Full Text Available OBJECTIVES: Severe asthma is found in approximately 10% of patients with asthma. Some factors associated with worse asthma control include rhinitis, gastroesophageal reflux disease, vocal cord dysfunction (VCD, nasal polyposis and bronchiectasis. Therefore, we evaluated the prevalence of these illnesses in patients with severe asthma. METHODS: We conducted a retrospective analysis of data obtained from electronic medical records of patients with severe asthma between January 2006 and June 2008. Symptoms of rhinitis and gastroesophageal reflux disease were evaluated as well as intolerance to nonsteroidal anti-inflammatory drugs. We evaluated the results of esophagogastroduodenoscopy, videolaryngoscopy and CT scans of the chest in order to confirm gastroesophageal reflux disease, nasal polyposis, vocal cord dysfunction and bronchiectasis. RESULTS: We evaluated 245 patients. Rhinitis symptoms were present in 224 patients (91.4%; 18 (7.3% had intolerance to nonsteroidal anti-inflammatory drugs, and 8 (3.3% had nasal polyposis. Symptoms of gastroesophageal reflux disease were reported for 173 (70.6% patients, although the diagnosis of gastroesophageal reflux disease was confirmed based on esophagogastroduodenoscopy or laryngoscopy findings in just 58 (33.6% patients. Vocal cord dysfunction was suspected in 16 (6.5% and confirmed through laryngoscopy in 4 (1.6%. The patient records provided CT scans of the chest for 105 patients, and 26 (24.8% showed bronchiectasis. DISCUSSION: Rhinitis and gastroesophageal reflux disease were the most common comorbidities observed, in addition to bronchiectasis. Therefore, in patients with severe asthma, associated diseases should be investigated as the cause of respiratory symptoms and uncontrolled asthma.

    Full Text Available Asma é uma doença com uma alta prevalência em nosso meio e ao redor do mundo. Embora novas opções terapêuticas tenham sido recentemente desenvolvidas, parece haver um aumento mundial na sua morbidade e mortalidade. Em muitas instituições, as exacerbações asmáticas ainda se constituem em uma emergência médica muito comum. As evidências têm demonstrado que o manejo da asma aguda na sala de emergência concentra decisões cruciais que podem determinar o desfecho desta situação clínica. Nesta revisão, enfocaremos a avaliação e o tratamento do paciente com asma aguda na sala de emergência, descrevendo uma estratégia apropriada para o seu manejo. Serão consideradas as seguintes etapas: diagnóstico, avaliação da gravidade, tratamento, avaliação das complicações, decisão sobre onde se realizará o tratamento adicional e orientações por ocasião da alta da emergência. Espera-se que estas recomendações contribuam para que o médico clínico tome as decisões apropriadas durante o manejo da asma aguda na sala de emergência.Asthma is a disease with high prevalence in our country and worldwide.

Sebastiano Hospital, Correggio, Italy Abstract: Asthma is a complex disorder frequently associated with a poor symptom control, concomitant morbidity, mortality, and significant health care costs due to lack of compliance or inadequate therapeutic options. Interleukin-5 (IL-5 plays a key role in the pathogenesis of eosinophilic disorders, and in the latest years has become a definite target for treatment. Besides asthma, other hypereosinophilic disorders include the hypereosinophilic syndrome, eosinophilic granulomatosis with polyangiitis, sinonasal polyposis, COPD with eosinophilic airway inflammation, allergic rhinitis, atopic dermatitis, eosinophilic esophagitis. The introduction of mepolizumab, a fully humanized monoclonal antibody that binds to IL-5, may represent a useful therapeutic option to control exacerbations and improve asthma-related quality of life in a subgroup of patients with persistent airway eosinophilia and moderate to severe asthma. Several studies carried out in recent years allow, at present, a careful patient selection for appropriate individualized treatment in severe asthma. Further research is anyway needed in order to better understand the pathogenetic mechanisms of asthma and to find new biomarkers. The high costs of biological agents as compared with standard drugs may be largely offset by increased clinical efficacy and good safety profile in selected patients.

    2013-02-01

    Full Text Available Abstract Background Severe asthma is a heterogeneous disease and the relationship between airway inflammation and airway remodelling is poorly understood. We sought to define sputum mediator profiles in severe asthmatics categorised by CT-determined airway geometry and sputum differential cell counts. Methods In a single centre cross-sectional observational study we recruited 59 subjects with severe asthma that underwent sputum induction and thoracic CT. Quantitative CT analysis of the apical segment of the right upper lobe (RB1 was performed. Forty-one mediators in sputum samples were measured of which 21 mediators that were assessable in >50% of samples were included in the analyses. Results Independent of airway geometry, sputum MMP9 and IL-1β were elevated in those groups with a high sputum neutrophil count while sputum ICAM was elevated in those subjects with a low sputum neutrophil count. In contrast, sputum CCL11, IL-1α and fibrinogen were different in groups stratified by both sputum neutrophil count and airway geometry. Sputum CCL11 concentration was elevated in subjects with a low sputum neutrophil count and high luminal and total RB1 area, whereas sputum IL1α was increased in subjects with a high sputum neutrophil count and low total RB1 area. Sputum fibrinogen was elevated in those subjects with RB1 luminal narrowing and in those subjects with neutrophilic inflammation without luminal narrowing. Conclusions We have demonstrated that sputum mediator profiling reveals a number of associations with airway geometry. Whether these findings reflect important biological phenotypes that might inform stratified medicine approaches requires further investigation.

    Full Text Available Childhood asthma is a recurring health burden and symptoms of severe asthma in children are also emerging as a health and economic issue. This study examined changing patterns in symptoms of severe asthma and allergies (ever eczema and hay fever, using the Irish International Study of Asthma and Allergies in Childhood (ISAAC protocol. ISAAC is a cross-sectional self-administered questionnaire survey of randomly selected representative post-primary schools. Children aged 13–14 years were studied: 2,670 (in 1995, 2,273 (in 1998, 2,892 (in 2002–2003, and 2,805 (in 2007. Generalized linear modelling using Poisson distribution was employed to compute adjusted prevalence ratios (PR. A 39% significant increase in symptoms of severe asthma was estimated in 2007 relative to the baseline year 1995 (adjusted PR: 1.39 [95% CI: 1.14–1.69] increasing from 12% in 1995 to 15.3% in 2007. Opposite trends were observed for allergies, showing a decline in 2007, with an initial rise. The potential explanations for such a complex disease pattern whose aetiological hypothesis is still evolving are speculative. Changing environmental factors may be a factor, for instance, an improvement in both outdoor and indoor air quality further reinforcing the hygiene hypothesis but obesity as a disease modifier must also be considered.

    Asthma is a chronic disorder that can place considerable restrictions on the physical, emotional, and social aspects of the lives of patients. Inhaled glucocorticoids (GCs) are the most effective controller therapy. The purpose of this study was to evaluate the effect of inhaled GCs on quality of life in patients with moderate to severe asthma. Patients completed the asthma quality of life questionnaire (AQLQ) and pulmonary function test at baseline and after 4 wks treatment of GCs. We enrolled 60 patients who had reversibility in FEV1 after 200 microgram of albuterol of 15% or more and/or positive methacholine provocation test, and initial FEV1% predicted less than 80%. All patients received inhaled GCs (fluticasone propionate 1,000 microgram/day) for 4 wks. The score of AQLQ was significantly improved following inhaled GCs (overall 51.9+/-14.3 vs. 67.5+/-12.1, presponsiveness. Quality of life was improved after inhaled GCs regardless of asthma severity and GCs responsiveness in patients with moderate to severe asthma. PMID:16100448

    We present a case of a 49-year-old man, with a 10-year history of bronchial asthma and nasal polyposis, who developed acutely painful paraplegia and paresthesias. Laboratory data showed elevated blood creatine kinase levels and myoglobinuria, which were diagnostic for rhabdomyolysis but only partially explained the neurological deficit. Electrophysiological studies revealed a sensorimotor neuropathy of multiple mononeuritis type. The patient also had leucocytosis with marked eosinophilia and antineutrophil cytoplasmic autoantibodies. Bronchial biopsies showed inflammatory infiltrates with a prevalence of eosinophils. All these findings led us to diagnose eosinophilic granulomatosis with polyangiitis, a systemic vasculitis with almost constant respiratory tract involvement and good response to corticosteroid treatment. This can also affect other organs including the nervous system, while muscular involvement is unusual. Some diseases deserve attention in differential diagnosis. Histology can support the diagnosis which remains essentially clinical. Steroid sparing agents/immunosuppressants are suggested for extensive disease. PMID:24980994

  12. Comparative efficacy of terbutaline administered by Nebuhaler and by nebulizer in young children with acute asthma.

    We compared the use of terbutaline sulphate that was delivered by a nebulizer with its delivery by a Nebuhaler at two dose levels in 27 children (nine children per group) of between three and six years of age with acute asthma. No significant difference was found in the mean baseline clinical score among the three groups, and a significant decline occurred in the mean clinical scores in all groups by 15 minutes which was maintained to 60 minutes after the dose was administered. The decline that was achieved with delivery of the drug by way of a Nebuhaler (at either dose level) was not significantly different from that with a nebulizer, although cooperation with Nebuhaler usage was not universal in the age-group.

    Full Text Available Metamizole or dipyrone is a pyrazolone derivative that belongs to the non-steroidal anti-inflammatory drugs. Its main side-effect is hematological toxicity. Thrombocytopenia due to metamizole is rare and is usually associated with the involvement of the two other blood series. Drug-induced thrombocytopenia is more frequently related to immune mechanisms, and the diag-nosis is still largely made by exclusion of other causes and by correlation of timing of thrombocytopenia with the administration of drug. Metamizole may cause acute renal failure due to hemodynamic renal failure/acute tubular necrosis and/or acute tubulointerstitial nephritis. We report a case of acute renal failure and severe thrombocytopenia after metamizole. As far as we know, this combination of adverse effects from this drug has not been reported previously.

    2012-01-01

    Full Text Available Context Acute pancreatitis can lead to prolonged fasting and malnutrition. Many metabolic changes, including thiamine deficiency, may lead to the well know pancreatic encephalopathy. In this condition however the thiamine deficiency is rarely suspected. Case report We report the case of a 17-year-old woman with severe acute pancreatitis who developed mental status changes and ophthalmoplegia. A magnetic resonance image showed hyperintensive signals in periventricular areas, medial thalamus, and mammillary bodies, findings consistent with the diagnosis of Wernicke encephalopathy. Thiamine treatment reversed neurological complications. Conclusion Wernicke encephalopathy secondary to thiamine deficiency should be considered as a possible cause of acute mental status changes in patients with acute pancreatitis and malnutrition. Prophylactic doses of thiamine could be considered in susceptible patients.

  18. Current concept of pathogenesis of severe acute pancreatitis

    Xie Ning Wu

    2000-01-01

    @@ The pathogenesis of severe acute pancreatitis is very complicated. It is a multifactorial as well as multifaceted disease. First of all, the etiologic agents initiate the pancreatic acinar injury by release of pancreatic enzymes and overstimulation of macrophages and neutrophils, then the cytokines and inflammatory mediators are liberated. There is also interaction between neutrophils and endothelial cells producing free radicals, the cytokines cause increasing vascular permeability, activating complement component, resulting in microcirculatory impairment and imbalance of thrombo-fibrinolytic system. Many of these events occur not only in the pancreas itself, but also in the other vital organs and tissues, leading to severe acute pancreatitis and complications. The sequencial events are as follows.

  2. Cost-Effectiveness of Bronchial Thermoplasty, Omalizumab, and Standard Therapy for Moderate-to-Severe Allergic Asthma.

    Zafar Zafari

    Full Text Available Bronchial thermoplasty (BT is a recently developed treatment for patients with moderate-to-severe asthma. A few studies have suggested the clinical efficacy of this intervention. However, no study has evaluated the cost-effectiveness of BT compared to other alternative treatments for moderate-to-severe allergic asthma, which currently include omalizumab and standard therapy.To evaluate the cost-effectiveness of standard therapy, BT, and omalizumab for moderate-to-severe allergic asthma in the USA.A probabilistic Markov model with weekly cycles was developed to reflect the course of asthma progression over a 5-year time horizon. The study population was adults with moderate-to-severe allergic asthma whose asthma remained uncontrolled despite using high-dose inhaled corticosteroids (ICS, with or without long-acting beta-agonists [LABA]. A perspective of the health-care system was adopted with asthma-related costs as well as quality-adjusted life years (QALYs and exacerbations as the outcomes.For standard therapy, BT, and omalizumab, the discounted 5-year costs and QALYs were $15,400 and 3.08, $28,100 and 3.24, and $117,000 and 3.26, respectively. The incremental cost-effectiveness ratio (ICER of BT versus standard therapy and omalizumab versus BT was $78,700/QALY and $3.86 million/QALY, respectively. At the willingness-to-pay (WTP of $50,000/QALY and $100,000/QALY, the probability of BT being cost-effective was 9%, and 67%, respectively. The corresponding expected value of perfect information (EVPI was $155 and $1,530 per individual at these thresholds. In sensitivity analyses, increasing the costs of BT from $14,900 to $30,000 increased its ICER relative to standard therapy to $178,000/QALY, and decreased the ICER of omalizumab relative to BT to $3.06 million/QALY. Reducing the costs of omalizumab by 25% decreased its ICER relative to BT by 29%.Based on the available evidence, our study suggests that there is more than 60% chance that BT becomes

    Full Text Available AbstractObjective: To describe the clinical characteristics, lung function, radiological findings, and the inflammatory cell profile in induced sputum in children and adolescents with severe therapy-resistant asthma (STRA treated at a referral center in southern Brazil.Methods: We retrospectively analyzed children and adolescents (3-18 years of age with uncontrolled STRA treated with high-dose inhaled corticosteroids and long-acting β2 agonists. We prospectively collected data on disease control, lung function, skin test reactivity to allergens, the inflammatory cell profile in induced sputum, chest CT findings, and esophageal pH monitoring results.Results: We analyzed 21 patients (mean age, 9.2 ± 2.98 years. Of those, 18 (86% were atopic. Most had uncontrolled asthma and near-normal baseline lung function. In 4 and 7, induced sputum was found to be eosinophilic and neutrophilic, respectively; the inflammatory cell profile in induced sputum having changed in 67% of those in whom induced sputum analysis was repeated. Of the 8 patients receiving treatment with omalizumab (an anti-IgE antibody, 7 (87.5% showed significant improvement in quality of life, as well as significant reductions in the numbers of exacerbations and hospitalizations.Conclusions: Children with STRA present with near-normal lung function and a variable airway inflammatory pattern during clinical follow-up, showing a significant clinical response to omalizumab. In children, STRA differs from that seen in adults, further studies being required in order to gain a better understanding of the disease mechanisms.

  4. Early Prediction of Severity in Acute Pancreatitis. Is This Possible?

    Sandberg AA

    2002-09-01

    Full Text Available One out of ten cases of acute pancreatitis develops into severe acute pancreatitis which is a life threatening disorder with a high mortality rate. The other nine cases are self limiting and need very little therapy. The specificity of good clinical judgement on admission, concerning the prognosis of the attack, is high (high specificity but misses a lot of severe cases (low sensitivity. The prediction of severity in acute pancreatitis was first suggested by John HC Ranson in 1974. Much effort has been put into finding a simple scoring system or a good biochemical marker for selecting the severe cases of acute pancreatitis immediately on admission. Today C-reactive protein is the method of choice although this marker is not valid until 48-72 hours after the onset of pain. Inflammatory mediators upstream from CRP like interleukin-6 and other cytokines are likely to react faster and preliminary results for some of these mediators look promising. Another successful approach has been to study markers for the activation of trypsinogen such as TAP and CAPAP. This is based on studies showing that active trypsin is the initial motor of the inflammatory process in acute pancreatitis. In the near future a combined clinical and laboratory approach for early severity prediction will be the most reliable. Clinical judgement predicts 1/3 of the severe cases on admission and early markers for either inflammation or trypsinogen activation should accurately identify 50-60% of the mild cases among the rest, thus missing only 2-4% of the remaining severe cases. One problem is that there is no simple and fast method to analyze any of these parameters.

  5. Self-hypnosis for anxiety associated with severe asthma: a case report

    Anbar Ran D

    2003-07-01

    Full Text Available Abstract Background Management of asthma can be complicated by both medical and psychiatric conditions, such as gastroesophageal reflux, chronic sinusitis, and anxiety. When symptoms of asthma are interpreted without regard to such conditions treatment may yield a suboptimal outcome. For example, anxiety-associated dyspnea, tachypnea, and chest tightness can be mistakenly interpreted as resulting from an exacerbation of asthma. Medical treatment directed only for asthma may thus lead to overuse of asthma medications and increased hospitalizations. Case Presentation The described case illustrates how a systemic steroid-dependent patient with asthma benefited from receiving care from a pediatric pulmonologist who also was well versed in the diagnosis and treatment of anxiety. By using self-hypnosis, the patient was able to reduce her dependence on bronchodilators. Following modification of her medical therapy under supervision of the pulmonologist, and regular use of hypnosis, the patient ultimately was weaned off her systemic steroid therapy. Conclusions This report emphasizes that anxiety must be considered as a comorbid condition in the treatment of asthma. Self-hypnosis can be a useful skill in the treatment of a patient with anxiety and asthma.

  6. Evaluation of the Correlation Between Body Mass Index and the Severity of Asthma in Recently Diagnosed Patients

    2011-06-01

    Full Text Available Introduction: Asthma and obesity are among diseases that cause several problems and impair quality of life.  The concurrence of these diseases, changes in the respiratory physiology, changes associated with obesity and limited activity associated with asthma may cause an interaction between the two conditions. Materials and Methods: We studied the epidemiologic characteristics of all recently diagnosed cases of asthma with no previous treatment who visited the Respiratory Diseases Clinic of the Ghaem Hospital from 2004 to 2007, their Body Mass Indexes (BMI were calculated and then spirometry was performed in all cases. Results: We studied 232 cases with the mean age of 38.96±12.94 years and the mean BMI of 27.05±4.92. Cough and exertional dyspnea were the most common clinical symptoms. In spirometric evaluations, the mean maximum mid-expiratory flow (MMEF increased with weight, which was not, however, insignificant. FVC in obese patients was significantly less than in normal weight cases. A significant correlation was not also seen between BMI and FEV1 (r=-0.023, P=0.729. Conclusion: Except for FVC which had a significant correlation with BMI, other studied indices yielded no significant results, which calls for more extensive studies with larger populations. Considering the fact that mild asthma is less common in obese patients, better weight control in asthmatic patients can promote their quality of life and make asthma management more effective.

    2011-09-01

    Full Text Available Asthma is a chronic inflammatory disease of the airways that may lead to limitations in regular activities, to hospitalizations and a decrease in quality of life. Adherence to drug treatment is crucial for control of the disease. The use of medicinal herbs can reduce adherence to prescriptions, as the medication may be replaced by infusions or herbal products. The objective of this study was to evaluate the frequency of use of traditional herbal medicine among severe asthmatics in Salvador. Information on use of homemade remedies was obtained through application of a questionnaire during patient visits to a referral center. We also collected data on economic and social aspects as well as disease control. One hundred and forty-four (91,1% out of one hundred and fifty-eight patients evaluated used herbal medicines, but only 26.5% attributed improvement of asthma symptoms to this alternative treatment and only 8 had substituted a prescribed medication by herbal medicines. There was a trend towards lower adherence to prescription drug treatment in this group of patients. Despite the high frequency of use of medicinal herbs in our sample, there was no improvement in the asthma treatment in this population compared to non-users. Adherence to conventional drug treatment was satisfactory and there was neither reduction in asthma control nor increase in hospitalizations among the users of medicinal plants.A asma é uma enfermidade inflamatória crônica das vias aéreas que pode resultar em limitações nas atividades diárias, internações e prejuízo da qualidade de vida.

  13. X-CT evaluation of the severity of acute pancreatitis

    In some patients with acute pancreatitis, some experience life-threatening complications. Although there are reports of the assessment of the severity of the disease, mainly based on clinical signs and laboratory findings, pertinent criteria remain elusive. As little information is available concerning the degree or extent of pancreatic lesions; it is difficult to predict the severity and outcome. I examined 74 patients with acute pancreatitis, using computed tomography (CT). The severity was evaluated by means of a CT-score consisting of ten points on the CT findings, in the early stage of the acute pancreatitis. The following results were obtained. 1) Infiltration into the retroperitoneal space such as anterior pararenal space was observed by CT earlier and more frequently than were changes within the pancreas parenchyma. 2) Heterogeneous density of the pancreas and involvement of the posterior pararenal space were more significant and frequently in the severe group than in the moderate or mild group. 3) CT observations made 48 hours after the onset were the most adequate for evaluating the severity in case of acute pancreatitis. 4) After evaluating the severity by the CT-score, the 74 patients were grouped into 3: mild in 46, moderate in 22 and severe in 6 patients. The CT-score revealed a significantly greater specifity and accuracy than did the clinical score, Forell's, Ranson's, or the criteria submitted by a committee for the study of this disease appointed by the Japanese Ministry of Health and Welfare. I propose that an evaluation of the severity by CT-score obtained about 48 hours after the onset of symptoms is useful for predicting the prognosis and for designing proper treatment. (author)

    Tay, Hock; Wark, Peter A B; Bartlett, Nathan W

    2016-06-01

    Viral exacerbations continue to represent the major burden in terms of morbidity, mortality and health care costs associated with asthma. Those at greatest risk for acute asthma are those with more severe airways disease and poor asthma control. It is this group with established asthma in whom acute exacerbations triggered by virus infections remain a serious cause of increased morbidity. A range of novel therapies are emerging to treat asthma and in particular target this group with poor disease control, and in most cases their efficacy is now being judged by their ability to reduce the frequency of acute exacerbations. Critical for the development of new treatment approaches is an improved understanding of virus-host interaction in the context of the asthmatic airway. This requires research into the virology of the disease in physiological models in conjunction with detailed phenotypic characterisation of asthma patients to identify targets amenable to therapeutic intervention.

  20. Does vitamin d deficiency contribute to the severity of asthma in children and adults

    Role of vitamin D in the health of bones has been well established for over decades. It was known that its deficiency caused rickets in children and osteomalacia in adults. Later it was discovered that these can be corrected by giving vitamin D. Researchers discovered that vitamin D can be synthesized by exposure to sun. Hence it was also named the sunshine vitamin. As time passed it was observed that low levels of vitamin D were associated with multiple diseases. This sparked the interest of the scientific community to further the research on vitamin D which led to the studies that started associating vitamin D with various diseases like cancers (prostate, colon and breast), autoimmune diseases (rheumatoid arthritis), infectious diseases (tuberculosis, hepatitis B, hepatitis C, HIV), cardiovascular diseases, mental illnesses (schizophrenia), diabetes mellitus (type 1, type 2 and gestational) and allergic conditions like asthma. With time, more studies were carried out relating levels of vitamin D to development of asthma, asthma exacerbations and risk factors leading to development of asthma like respiratory tract infections with positive associations. A number of studies were carried out which tried to explain the possible molecular mechanisms relating deficiency of vitamin D in pathogenesis of asthma. This review summarizes the role of vitamin D in development of asthma and probable mechanisms relating vitamin D to the pathogenesis of asthma. (author)

    Full Text Available Abstract Background The clinical manifestations of severe asthma are heterogeneous. Some individuals with severe asthma develop irreversible fixed airway obstruction, which is associated with poor outcomes. We therefore investigated the factors associated with fixed airway obstruction in Korean patients with severe asthma. Methods Severe asthma patients from a Korean adult asthma cohort were divided into two groups according to the results of serial pulmonary function tests. One group had fixed airway obstruction (FAO [forced expiratory volume in 1 second (FEV1/forced vital capacity (FVC ratio Results Multivariate analysis showed that longer duration of disease, greater amount of cigarette smoking and absence of rhinosinusitis were significantly related to the development of FAO in severe asthmatics. Other parameters, including atopic status, pattern of airway inflammatory cells in induced sputum, and frequency of asthma exacerbations did not differ between the FAO and RAO groups. Conclusion Severe asthma patients with longer disease duration and the absence of rhinosinusitis are more likely to develop FAO. This study also demonstrates the importance of quitting smoking in order to prevent irreversible airway obstruction. Further investigation is required to determine the mechanism by which these factors can modify the disease course in Korean patients with severe asthma.

  3. Mode of dendritic cell activation: the decisive hand in Th2/Th17 cell differentiation. Implications in asthma severity?

    Vroman, Heleen; van den Blink, Bernt; Kool, Mirjam

    2015-02-01

    Asthma is a heterogeneous chronic inflammatory disease of the airways, with reversible airflow limitations and airway remodeling. The classification of asthma phenotypes was initially based on different combinations of clinical symptoms, but they are now unfolding to link biology to phenotype. As such, patients can suffer from a predominant eosinophilic, neutrophilic or even mixed eosinophilic/neutrophilic inflammatory response. In adult asthma patients, eosinophilic inflammation is usually seen in mild-to-moderate disease and neutrophilic inflammation in more severe disease. The underlying T cell response is predominated by T helper (Th) 2, Th17, or a mixed Th2/Th17 cell immune response. Dendritic cells (DCs) are "professional" antigen presenting cells (APCs), since their principal function is to present antigens and induce a primary immune response in resting naive T cells. DCs also drive the differentiation into distinctive Th subsets. The expression of co-stimulatory molecules and cytokines by DCs and surrounding cells determines the outcome of Th cell differentiation. The nature of DC activation will determine the expression of specific co-stimulatory molecules and cytokines, specifically needed for induction of the different Th cell programs. Thus DC activation is crucial for the subsequent effector Th immune responses. In this review, we will discuss underlying mechanisms that initiate DC activation in favor of Th2 differentiation versus Th1/Th17 and Th17 differentiation in the development of mild versus moderate to severe asthma.

    BACKGROUND: The airway epithelium is exposed to a range of physical and chemical irritants in the environment that are known to trigger asthma. Transient receptor potential (TRP) cation channels play a central role in sensory responses to noxious physical and chemical stimuli. Recent genetic evidence suggests an involvement of transient receptor potential vanilloid 1 (TRPV1), one member of the vanilloid subfamily of TRP channels, in the pathophysiology of asthma. The functional expression of ...

    Associations between historical, presenting, and treatment-related characteristics and relapse within 8 weeks after a moderate to severe asthma exacerbation were studied in a cohort of 284 adult asthmatics. Data were collected prospectively, and a multivariate model was developed and internally validated. Within 10 days, only 8% had relapsed, increasing to 45% by 8 weeks. Three variables that could be identified at the time of discharge were independently associated with relapse. These included: having made three or more visits to an emergency department in the prior 6 months (hazard ratio (HR) = 2.3, 95% CI = 1.6-3.4); difficulty performing work or activities as a result of physical health in the 4 weeks prior (HR = 2.7, 95% CI = 1.6-4.3); discontinuing hospital-based treatment for the exacerbation within 24 hours without having achieved a peak expiratory flow rate of at least 50% of predicted (HR = 2.6, 95% CI = 1.6-4.1). These risk factors may help to identify patients with poorly controlled asthma in need of more intensive and comprehensive management. PMID:9474071

    Isolates of rhinovirus C (RV-C), a recently identified Enterovirus (EV) species, are the causative agents of severe respiratory infections among children and are linked to childhood asthma exacerbations. The RV-C have been refractory to structure determination because they are difficult to propagate in vitro. Here, we report the cryo-EM atomic structures of the full virion and native empty particle (NEP) of RV-C15a. The virus has 60 "fingers" on the virus outer surface that probably function as dominant immunogens. Because the NEPs also display these fingers, they may have utility as vaccine candidates. A sequence-conserved surface depression adjacent to each finger forms a likely binding site for the sialic acid on its receptor. The RV-C, unlike other EVs, are resistant to capsid-binding antiviral compounds because the hydrophobic pocket in VP1 is filled with multiple bulky residues. These results define potential molecular determinants for designing antiviral therapeutics and vaccines. PMID:27511920

    Background Comorbidities have a serious impact on the frequent severe acute exacerbations (AEs) in patients with COPD. Previous studies have used the Charlson comorbidity index to represent a conglomerate of comorbidities; however, the respective contribution of each coexisting disease to the frequent severe AEs remains unclear. Methods A retrospective, observational study was performed in 77 COPD patients who experienced severe AE between January 2012 and December 2014 and had at least 1-year follow-up period from the date of admission for severe AE. We explored the incidence of frequent severe AEs (≥2 severe AEs during 1-year period) in these patients and investigated COPD-related factors and comorbidities as potential risk factors of these exacerbations. Results Out of 77 patients, 61 patients (79.2%) had at least one comorbidity. During a 1-year follow-up period, 29 patients (37.7%) experienced frequent severe AEs, approximately two-thirds (n=19) of which occurred within the first 90 days after admission. Compared with patients not experiencing frequent severe AEs, these patients were more likely to have poor lung function and receive home oxygen therapy and long-term oral steroids. In multiple logistic regression analysis, coexisting asthma (adjusted odds ratio [OR] =4.02, 95% confidence interval [CI] =1.30–12.46, P=0.016), home oxygen therapy (adjusted OR =9.39, 95% CI =1.60–55.30, P=0.013), and C-reactive protein (adjusted OR =1.09, 95% CI =1.01–1.19, P=0.036) were associated with frequent severe AEs. In addition, poor lung function, as measured by forced expiratory volume in 1 second (adjusted OR =0.16, 95% CI =0.04–0.70, P=0.015), was inversely associated with early (ie, within 90 days of admission) frequent severe AEs. Conclusion Based on our study, among COPD-related comorbidities, coexisting asthma has a significant impact on the frequent severe AEs in COPD patients. PMID:27536097

    Bronchial asthma (BA) is one of the common chronic diseases of childhood. Vitamin D deficiency has been associated with BA. Suppressor regulatory T cells (Treg) are important for the induction, maintenance of immunological tolerance to allergens. This study assessed serum 25-hydroxyvitamin D (vitamin D) and the percentages of CD4+CD25+(high) Foxp3+ Treg, in peripheral blood, as predictors of asthma severity and level of clinical control. The study enrolled 72 children divided equally between asthmatic children (AC) and age and sex matched controls. Diagnostic criteria and level of asthma severity followed the Global Initiative for Asthma guidelines. Serum vitamin D was determined by an immunoassay and the percentages of CD4+CD25+ig Foxp3+ Treg by flow cytometry. Serum vitamin D level and percentage of CD4+CD25+(high) Treg were lower in AC compared to controls (P asthma compared to mild and moderate forms (P = 0.008) and in uncontrolled attacks compared to partially or completely controlled children. No difference in percentage of Treg in relation to asthma severity and clinical control was observed. Since AC has decreased serum vitamin D with inverse relationship between its levels and asthma severity, we conclude that it can be used to predict severity of asthma. PMID:26415368

    Rationale/statement of the problem : Considerable research has focused on the relationship of anxiety with alterations in the hypothalamic-pituitary-adrenal (HPA) acute stress response. Findings, however, differ among studies on adults and children, and among different types of anxiety. This study investigates the relationship of anxiety symptom severity with HPA reactivity to the cold pressor task (CPT) in preadolescent children. We hypothesize that children with increased symptoms of anxiet...

  13. Establishment of a better pig model of severe acute pancreatitis

    Objective: To establish a new severe acute pancreatitis (SAP) pig model for evaluating enteral administration therapy. Methods: Eight tai-lake plum-mountain pigs were randomized into the SAP group(n=4) and the control group(n=4). In anaesthetised eight pigs were orthophoric inserted a nasojejunal catheter. In the SAP group the pancreatic duct was cannulated and taurocholic acid was infused to induce severe acute pancreatitis. Pigs in the control group were cannulated alone and served as the controls. Temperature, bowel sounds, serum amylase, computed tomography (CT) scores and histologic examination were compared between the two groups, to confirm that whether pancreatitis model was established or catheter was inserted. Results: Compared with the control group, SAP group serum amylase was obviously increased (P<0.05). Both CT and histologic examination demonstrated that severe acute pancreatitis model was established and nasojejunal catheter was inserted successfully. Conclusion: It is a simple, noninvasive, repeatable model of enteral nutrition and administration through intestinum in pancreatitis treatment. (authors)

    AIM: To assess the early predictability of the soluble CD40L (sCD40L) in pancreatitis severity.METHODS: Between February 2000 and February 2003,279 consecutive patients with acute pancreatitis were prospectively enrolled in our study. In this report, 40 patients with mild and 40 patients with severe pancreatitis were randomly studied. sCD40L concentrations were measured 48 hours after admission.RESULTS: sCD40L levels were significantly higher 48 hours after admission in severe pancreatitis than in mild pancreatitis. Using a cutoff of 1000 pg/L, the sensitivity and specificity of sCD40L to detect a severe course of the disease were 78% and 62% respectively compared to 72% and 81% for CRP. Logistic regression analysis found that CRP was the only statistically significant marker able to detect a severe course of the disease.CONCLUSION: These findings indicate that CRP remains a valuable marker to determine the severity and prognosis of acute pancreatitis whereas sCD40L levels should be assessed in further studies.

  16. Defective Resensitization in Human Airway Smooth Muscle Cells Evokes β-Adrenergic Receptor Dysfunction in Severe Asthma.

    Manveen K Gupta

    Full Text Available β2-adrenergic receptor (β2AR agonists (β2-agonist are the most commonly used therapy for acute relief in asthma, but chronic use of these bronchodilators paradoxically exacerbates airway hyper-responsiveness. Activation of βARs by β-agonist leads to desensitization (inactivation by phosphorylation through G-protein coupled receptor kinases (GRKs which mediate β-arrestin binding and βAR internalization. Resensitization occurs by dephosphorylation of the endosomal βARs which recycle back to the plasma membrane as agonist-ready receptors. To determine whether the loss in β-agonist response in asthma is due to altered βAR desensitization and/or resensitization, we used primary human airway smooth muscle cells (HASMCs isolated from the lungs of non-asthmatic and fatal-asthmatic subjects. Asthmatic HASMCs have diminished adenylyl cyclase activity and cAMP response to β-agonist as compared to non-asthmatic HASMCs. Confocal microscopy showed significant accumulation of phosphorylated β2ARs in asthmatic HASMCs. Systematic analysis of desensitization components including GRKs and β-arrestin showed no appreciable differences between asthmatic and non-asthmatic HASMCs. However, asthmatic HASMC showed significant increase in PI3Kγ activity and was associated with reduction in PP2A activity. Since reduction in PP2A activity could alter receptor resensitization, endosomal fractions were isolated to assess the agonist ready β2ARs as a measure of resensitization. Despite significant accumulation of β2ARs in the endosomes of asthmatic HASMCs, endosomal β2ARs cannot robustly activate adenylyl cyclase. Furthermore, endosomes from asthmatic HASMCs are associated with significant increase in PI3Kγ and reduced PP2A activity that inhibits β2AR resensitization. Our study shows that resensitization, a process considered to be a homeostasis maintaining passive process is inhibited in asthmatic HASMCs contributing to β2AR dysfunction which may underlie

    2012-01-01

    Full Text Available Early intensive care for severe acute pancreatitis is essential for improving SAP mortality rates. However, intensive therapies for SAP are often delayed because there is no ideal way to accurately evaluate severity in the early stages. Currently, perfusion CT has been shown useful to predict prognosis of SAP in the early stage. In this presented paper, we would like to review the clinical usefulness and limitations of perfusion CT for evaluation of local and systemic complications in early stage of SAP.

  19. Continuous Inhalation of Ipratropium Bromide for Acute Asthma Refractory to β2-agonist Treatment.

    2015-01-01

    To present the case of a patient with persistent bronchospasm, refractory to treatment with β2-agonists, that resolved promptly with continuous inhalation of large dose (1000 mcg/hr) ipratropium bromide, and to discuss the possibility of tolerance to β2-agonists as the cause for his failure to respond to adrenergic medications. The patient had received multiple doses of albuterol, as well as subcutaneous terbutaline (0.3 mg), intravenous magnesium sulfate (1 g) and intravenous dexamethasone (10 mg) prior to his admission to the intensive care unit. He remained symptomatic despite systemic intravenous steroids, continuous intravenous terbutaline (up to 0.6 mcg/kg/min), and continuous nebulized albuterol (up to 20 mg/hr for 57 hr) followed by 49 hours of continuous levalbuterol (7 mg/hr). Due to the lack of response, all β2-agonists were discontinued at 106 hours post-admission, and he was started on large dose ipratropium bromide (1000 mcg/hr) by continuous nebulization. Clinical improvement was evident within 1 hour and complete resolution of his symptoms within 4 hours. Continuous inhalation of large dose ipratropium bromide may be an effective regimen for the treatment of patients hospitalized with acute asthma who are deemed to be nonresponsive and/or tolerant to β2-agonist therapy.

    Objective: To evaluate paranasal sinuses in patients with stable or acute asthma in order to determine the prevalence of acute bacterial rhinosinusitis. Methods: A cross-sectional study including 30 patients with acute asthma (73% females) treated in the emergency room and 30 patients with stable asthma (80% females) regularly monitored as outpatients. All patients completed a questionnaire on respiratory signs and symptoms and were submitted to ear, nose and throat (ENT) examination, as well as to X-ray and computed tomography (CT) imaging of the sinuses. Results: Based on the clinical diagnosis, the prevalence of acute bacterial rhinosinusitis was 40% in the patients with acute asthma and 3% in those with stable asthma. The ENT examination findings and the imaging findings in isolation were not useful to confirm the diagnosis. Conclusions: In themselves, ENT examination findings, X-ray findings and CT findings were not useful for the diagnosis of acute bacterial rhinosinusitis. Our results provide further evidence that a clinical diagnosis of bacterial rhinosinusitis should be made with caution. (author)

    To assess the usefulness of a CT severity index(CTSI) for the evaluation of acute pancreatitis and to correlate it with clinical findings. We retrospectively evaluated contrast enhanced CT in 34 patients with acute pancreatitis. They were categorized into low-score(0-2), middle-socre(3-6), and high-score(7-10) groups according to CTSI points, and those groups were correlated with duration of fasting period, days in hospital morbidity and mortality. We attempted to determine the differences in CTSI between pancreatitis caused by alcohol and by biliary tract disease. Of 34 patients, 11 were placed in the low-score group, 19 in the middle-score group, and 4 in the high-score group. The patients in the middle-score group experienced longer fasting period and stayed longer in hospital than those in the low-score group(p < .05 and p= .08, respectively). Morbidity was 0% in the low-score group, 37% in the middle-score group and 50% in the high-score group. Mortality occurred in two patients in high-score group, only. Alcohol-induced pancreatitis generally showed a higher CTSI and more severe clinical course than pancreatitis caused by biliary tract disease. In the evaluation of acute pancreatitis, CTSI can be a useful predictor of its prognosis.

  7. Incidence and risk factors for exacerbations of asthma during pregnancy

    2013-05-01

    Full Text Available Zarqa Ali, Charlotte Suppli UlrikDepartment of Pulmonary Medicine, Hvidovre Hospital and University of Copenhagen, Copenhagen, DenmarkBackground: Asthma is one of the most common chronic diseases among pregnant women. Acute exacerbations of asthma during pregnancy have an unfavorable impact on pregnancy outcome. This review provides an overview of current knowledge of incidence, mechanisms, and risk factors for acute exacerbations of asthma during pregnancy.Methods: A narrative literature review was carried out using the PubMed database.Results: During pregnancy, up to 6% of women with asthma are hospitalized for an acute exacerbation. The maternal immune system is characterized by a very high T-helper-2:T-helper-1 cytokine ratio during pregnancy and thereby provides an environment essential for fetal survival but one that may aggravate asthma. Cells of the innate immune system such as monocytes and neutrophils are also increased during pregnancy, and this too can exacerbate maternal asthma. Severe or difficult-to-control asthma appears to be the major risk factor for exacerbations during pregnancy, but studies also suggest that nonadherence with controller medication and viral infections are important triggers of exacerbations during pregnancy. So far, inconsistent findings have been reported regarding the effect of fetal sex on exacerbations during pregnancy. Other risk factors for exacerbation during pregnancy include obesity, ethnicity, and reflux, whereas atopy does not appear to be a risk factor.Discussion: The incidence of asthma exacerbations during pregnancy is disturbingly high. Severe asthma – better described as difficult-to-control asthma – nonadherence with controller therapy, viral infections, obesity, and ethnicity are likely to be important risk factors for exacerbations of asthma during pregnancy, whereas inconsistent findings have been reported with regard to the importance of sex of the fetus.Keywords: acute exacerbations

    Full Text Available Acute kidney injury (AKI is an important cause of morbidity and mortality in severe acute pancreatitis (SAP. We aimed in our study to explore the risk factors of AKI in patients with SAP and assess the prognosis of patients with SAP and AKI. This is a retrospective study consisting of analysis of outcome and complications encountered in 72 severe acute pancreatitis patients admitted to a tertiary care center at Indore, India, from May 2011 to April 2012. We encountered 14 AKI cases in the SAP study patients. There was a significant association of diabetes and alcohol with AKI in patients with SAP. Alcohol was found to be an independent significant risk factor for AKI in SAP. All the eight patients with SAP who expired had AKI. None of the patients of SAP without AKI expired during the study. We conclude that the patients with SAP with AKI have a greater mortality rate as compared with the SAP patients without AKI.

    Acute fatty liver of pregnancy is a rare disease that affects women in the third trimester of pregnancy. Although infrequent, the disease can cause maternal mortality. The diagnosis is not always clear until the pregnancy is terminated, and significant complications, such as acute pancreatitis, can occur. Pancreatic involvement typically only occurs in severe cases after the development of hepatic and renal impairment. To date, little knowledge is available regarding how the disease causes pancreatitis. Treatment involves supportive measures and pregnancy interruption. In this report, we describe a case of a previously healthy 26-year-old woman at a gestational age of 27 wk and 6 d who was admitted with severe abdominal pain and vomiting. This case illustrates the clinical and laboratory overlap between acute fatty liver of pregnancy and pancreatitis, highlighting the difficulties in differentiating each disease. Furthermore, the hypothesis for this overlapping is presented, and the therapeutic options are discussed.

  11. A PAF receptor antagonist inhibits acute airway inflammation and late-phase responses but not chronic airway inflammation and hyperresponsiveness in a primate model of asthma

    1992-01-01

    Full Text Available We have examined the effects of a PAF receptor antagonist, WEB 2170, on several indices of acute and chronic airway inflammation and associated changes in lung function in a primate model of allergic asthma. A single oral administration WEB 2170 provided dose related inhibition of the release of leukotriene C4 (LTC4 and prostaglandin D2 (PGD2 recovered and quantified in bronchoalveolar lavage (BAL fluid obtained during the acute phase response to inhaled antigen. In addition, oral WEB 2170 treatment in dual responder primates blocked the acute influx of neutrophils into the airways as well as the associated late-phase airway obstruction occurring 6 h after antigen inhalation. In contrast, a multiple dosing regime with WEB 2170 (once a day for 7 consecutive days failed to reduce the chronic airway inflammation (eosinophilic and associated airway hyperresponsiveness to inhaled methacholine that is characteristic of dual responder monkeys. Thus, we conclude that the generation of PAF following antigen inhalation contributes to the development of lipid mediators, acute airway inflammation and associated late-phase airway obstruction in dual responder primates; however, PAF does not play a significant role in the maintenance of chronic airway inflammation and associated airway hyperresponsiveness in this primate model.

    Severe acute respiratory syndrome (SARS) is a serious disease with many puzzling features. We present a simple, dynamic model to assess the epidemic potential of SARS and the effectiveness of control measures. With this model, we analysed the SARS epidemic data in Beijing. The data fitting gives the basic case reproduction number of 2.16 leading to the outbreak, and the variation of the effective reproduction number reflecting the control effect. Noticeably, our study shows that the response time and the strength of control measures have significant effects on the scale of the outbreak and the lasting time of the epidemic.

    2005-01-01

    AIM: To determine whether the hematocrit (Hct) at admission or at 24 h after admission was associated with severe acute pancreatitis (AP), organ failure (OF), and pancreatic necrosis.METHODS: A total of 336 consecutive patients with a first AP episode were studied. Etiology, Hct values at admission and at 24 h, development of severe AP according to Atlanta's criteria, pancreatic necrosis, OF and mortality were recorded. Hemoconcentration was defined as Hct level >44% for males and >40% for females. The t-test and χ2 test were used to assess the association of hemoconcentration to the severity, necrosis and OF.Diagnostic accuracy was also determined.RESULTS: Biliary disease was the most frequent etiology(n = 148). Mean Hct levels at admission were 41±6%for females and 46±7% for males (P<0.01). Seventyeight (23%) patients had severe AP, and OF developed in 45 (13%) patients. According to contrast-enhanced computed tomography scan, 36% (54/150) patients showed pancreatic necrosis. Hct levels were elevated in58% (55/96) and 61% (33/54) patients with interstitial and necrotizing pancreatitis, respectively. Neither Hct levels at admission nor hemoconcentration at 24 h were associated with the severity, necrosis or OF. Sensitivity,specificity and positive predictive values for both determinations were very low; and negative predictive values were between 61% and 86%, being the highest value for OF.CONCLUSION: Hct is not a useful marker to predict a worse outcome in acute pancreatitis. In spite of the high negative predictive value of hemoconcentration, the prognosis gain is limited due to an already high incidence of mild disease.

    2003-01-01

    AIM: To investigate a formalized therapeutic guideline for hyperlipidemic severe acute pancreatitis (HL-SAP).METHODS: Thirty-two consecutive patients with severe acute pancreatitis were included in the clinical trial. All of them met the following five criteria for admission to the study, namely the Atlanta classification and stratification system for the clinical diagnosis of SAP, APACHEII score more than 8, time interval for therapeutic intervention less than 72 hours after onset of the disease, serum triglyceride (TG) level 6.8 mmol/l or over, and exdusion of other etiologies.They were divided into severe acute pancreatitis group (SAP,22 patients) and fulminant severe acute pancreatitis group (FSAP, 10 patients). Besides the conventional therapeutic measures, Penta-association therapywas also applied in the two groups, which consisted of blood purification (adsorption of triglyceride and hemofiltration), antihyperlipidemic agents (fluvastatin or lipanthyl), low molecular weight heparin (fragmin), insulin, topical application of Pixiao (a traditional Chinese medicine) over the whole abdomen, serum triglyceride,pro-inflammatory cytokines and anti-inflammatory cytokines were determined before blood purification (PF), at the end of blood purification (AFE) and on the 7th day after onset of the disease (AF7) respectively. Simultaneously, severity of the diseases was assessed by the APACHE Ⅱ system.Prognosis was evaluated by non-operation cure rate,absorption rate of pseudocyst, time interval pseudocyst absorption, hospital stay and survival rate.RESULTS: Serum triglyceride level (mmol/L), TNFα (U/mi) concentration and APACHE Ⅱ score were significantly decreased (P<0.05) at AFE and AF7, as compared with PF.However, serum IL-10 concentration (pg/ml) was increased significantly (P<0.001) at AFE, and decreased significantly (P<0.05) at AF7 when compared with PF. Operations: The First surgical intervention time was 55.8±42.6 days in SAP group (5 patients) and

    2016-01-01

    Full Text Available Background: Leukotriene modifiers have an established role in the management of chronic asthma but their role in acute asthma is still under evaluation. Objective: To study and compare the effects of oral montelukast with oral zileuton in acute asthma. Materials and Methods: This study included 120 asthmatics and was conducted from September 2012 to March 2014. Patients were randomized into three different groups to receive montelukast or zileuton or placebo in addition to standard treatment for asthma exacerbation. Peak expiratory flow rate (PEFR values, details of rescue medication and vital signs were recorded at 6 h, 12 h, 24 h, and 48 h of drug or placebo administration and at discharge. Additional recording was done in the morning (8-10 am following admission. The primary endpoint was the mean PEFR of each group at these time points; the secondary end point being the need for rescue medications. Results: The mean PEFR recordings of the three study groups - placebo, montelukast, and zileuton - respectively, at various time points were as follows: at 6 h (223.25 ± 90.40, 199.00 ± 82.52, 233.75 ± 84.05; P = 0.240; at 12 h (271.00 ± 109.38, 251.50 ± 101.44, 309.50 ± 129.63; P = 0.048; at 24 h (288.25 ± 114.26, 269.00 ± 107.51, 324.50 ± 127.88; P = 0.080; and at 48 h (295.00 ± 114.80, 293.50 ± 113.24, 344.75 ± 119.91; P = 0.015; discharge (305.00 ± 118.56, 305.25 ± 119.51, 361.25 ± 119.70; P = 0.010. The mean PEFR for the three study groups at 8-10 am on the morning following admission was 268.75 ± 111.43, 252.50 ± 99.99, 306.75 ± 114.44; P = 0.047. Total rescue doses needed were 10, 1, and 0, respectively (P = 0.049. Conclusion: Zileuton is better than montelukast as an additional drug in acute asthma and results in significant improvement in lung function, and reduction in the need for rescue medications.

  20. Pathogenesis of pancreatic encephalopathy in severe acute pancreatitis

    Xi-Ping Zhang; Hua Tian

    2007-01-01

    BACKGROUND:Pancreatic encephalopathy (PE) is a serious complication of severe acute pancreatitis (SAP). In recent years, more and more PE cases have been reported worldwide, and the onset PE in the early stage was regarded as a poor prognosis sign of SAP, but the pathogenesis of PE in SAP still has not been clariifed in the past decade. The purpose of this review is to elucidate the possible pathogenesis of PE in SAP. DATA SOURCES:The English-language literature concern-ing PE in this review came from the Database of MEDLINE (period of 1991-2005), and the keywords of severe acute pancreatitis and pancreatic encephalopathy were used in the searching. RESULTS:Many factors were involved in the pathogenesis of PE in SAP. Pancreatin activation, excessive release of cytokines and oxygen free radicals, microcirculation abnormalities of hemodynamic disturbance, ET-1/NO ratio, hypoxemia, bacterial infection, water and electrolyte imbalance, and vitamin B1 deifciency participated in the development of PE in SAP. CONCLUSIONS:The pathogenesis of PE in SAP has not yet been fully understood. The development of PE in SAP may be a multi-factor process. To ifnd out the possible inducing factor is essential to the clinical management of PE in SAP.

  1. Severe acute renal failure in a patient with diabetic ketoacidosis

    Al-Matrafi Jamila

    2009-01-01

    Full Text Available Acute renal failure (ARF is a rare but potentially fatal complication of diabetic ketoacidosis (DKA. Early recognition and aggressive treatment of ARF during DKA may im-prove the prognosis of these patients. We present a case report of a 12 year old female admitted to the hospital with severe DKA as the 1s t manifestation of her diabetes mellitus. She presented with severe metabolic acidosis, hypophosphatemia, and oliguric ARF. In addition, rhabdomyolysis was noted during the course of DKA which probably contributed to the ARF. Management of DKA and renal replacement therapy resulted in quick recovery of renal function. We suggest that early initiation of renal replacement therapy for patients with DKA developing ARF may improve the potentially poor outcome of patients with ARF associated with DKA.

    2006-01-01

    Full Text Available Abstract Background To compare the efficacy and safety of budesonide/formoterol (Symbicort® with formoterol (Oxis® in the treatment of patients with acute asthma who showed evidence of refractoriness to short-acting β2-agonist therapy. Methods In a 3 hour, randomized, double-blind study, a total of 115 patients with acute asthma (mean FEV1 40% of predicted normal and a refractory response to salbutamol (mean reversibility 2% of predicted normal after inhalation of 400 μg, were randomized to receive either budesonide/formoterol (320/9 μg, 2 inhalations at t = -5 minutes and 2 inhalations at 0 minutes [total dose 1280/36 μg] or formoterol (9 μg, 2 inhalations at t = -5 minutes and 2 inhalations at 0 minutes [total dose 36 μg]. The primary efficacy variable was the average FEV1 from the first intake of study medication to the measurement at 90 minutes. Secondary endpoints included changes in FEV1 at other timepoints and change in respiratory rate at 180 minutes. Treatment success, treatment failure and patient assessment of the effectiveness of the study medication were also measured. Results FEV1 increased after administration of the study medication in both treatment groups. No statistically significant difference between the treatment groups was apparent for the primary outcome variable, or for any of the other efficacy endpoints. There were no statistically significant between-group differences for treatment success, treatment failure or patient assessment of medication effectiveness. Both treatments were well tolerated. Conclusion Budesonide/formoterol and formoterol provided similarly rapid relief of acute bronchoconstriction in patients with asthma who showed evidence of refractoriness to a short-acting β2-agonist.

    Full Text Available OBJECTIVE: To describe and characterize local adverse effects (in the oral cavity, pharynx, and larynx associated with the use of inhaled corticosteroids (ICSs in patients with moderate or severe asthma. METHODS: This was a cross-sectional study involving a convenience sample of 200 asthma patients followed in the Department of Pharmaceutical Care of the Bahia State Asthma and Allergic Rhinitis Control Program Referral Center, located in the city of Salvador, Brazil. The patients were ≥ 18 years of age and had been using ICSs regularly for at least 6 months. Local adverse effects (irritation, pain, dry throat, throat clearing, hoarseness, reduced vocal intensity, loss of voice, sensation of thirst, cough during ICS use, altered sense of taste, and presence of oral candidiasis were assessed using a 30-day recall questionnaire. RESULTS: Of the 200 patients studied, 159 (79.5% were women. The mean age was 50.7 ± 14.4 years. In this sample, 55 patients (27.5% were using high doses of ICS, with a median treatment duration of 38 months. Regarding the symptoms, 163 patients (81.5% reported at least one adverse effect, and 131 (65.5% had a daily perception of at least one symptom. Vocal and pharyngeal symptoms were identified in 57 (28.5% and 154 (77.0% of the patients, respectively. The most commonly reported adverse effects were dry throat, throat clearing, sensation of thirst, and hoarseness. CONCLUSIONS: Self-reported adverse effects related to ICS use were common among the asthma patients evaluated here.

    2004-01-01

    AIM: To investigate the effects of rhubarb on severe acute pancreatitis (SAP) in rats.METHODS: Severe acute pancreatitis was induced by two intraperitoneal injections of cerulein (40 μg/kg body weight) plus 5-h restraint water-immersion stress. Rhubarb (75-150 mg/kg) was orally fed before the first cerulein injection.The degree of pancreatic edema, serum amylase level,local pancreatic blood flow (PBF), and histological alterations were investigated. The effects of rhubarb on pancreatic exocrine secretion in this model were evaluated by comparing with those of somatostatin.RESULTS: In the Cerulein+Stress group, severe edema and diffuse hemorrhage in the pancreas were observed,the pancreatic wet weight (11.60±0.61 g/Kg) and serum amylase (458 490±43 100 U/L) were markedly increased (P<0.01 vs control). In the rhubarb (150 mg/kg) treated rats, necrosis and polymorphonuclear neutrophil (PMN) infiltration in the pancreas were significantly reduced (P<0.01), and a marked decrease (50%) in serum amylase levels was also observed (P<0.01). PBF dropped to 38%(93±5 Ml/min per 100 g) of the control in the Cerulein+Stressgroup and partly recovered in the Cerulein+Stress+Rhubarb 150 mg group (135±12 Ml/min per 100 g) (P<0.01). The pancreatic exocrine function was impaired in the SAP rats.The amylase levels of pancreatic juice were reduced in the rats treated with rhubarb or somatostatin, comparing with that of untreated SAP group. The bicarbonate concentration of pancreatic juice was markedly elevated only in the rhubarb treated group (P<0.01).CONCLUSION: Rhubarb can exert protective effects on SAP, probably by inhibiting the inflammation of pancreas,improving pancreatic microcirculation, and altering exocrine secretion.

    2006-03-01

    Full Text Available The aim of this study was to compare efficacy combination of phormoterol/budesonide turbuhaler vs. salbutamol/ipratropium bromide nebulization. Main therapy for acute asthma is inhaled short acting β2-agonist. Asthma patients are using two drugs, controller and reliever. Recently there is device-containing combination of long-acting β2-agonist with rapid onset and corticosteroid. This combination can act as reliever and controller. An opened randomized clinical trial of 76 patients between the ages of 12 and 60 years presenting to Persahabatan Hospital with asthma score between 8-12 participated in this study. After initial evaluation, patients were divided into two groups. Thirty-eight patients were administered combination of formoterol/budesonide 4.5/160 µg via turbuhaler (T-group every 20 minutes, total of three doses, and another 38 of salbutamol/ipratropium bromide 2.5/0.25 mg via nebulizer (N-group also with the same manner. There were no statistical difference in sex, mean age, high, weight, initial PEFR, and asthma score between two groups. The significant increased of PEFR and decreased of asthma score were observed in both groups. However, there were no significant difference of PEFR and asthma score between the two groups within every time-interval. Adverse events were mild including hoarseness, tremor and palpitation. Of T-group, 1 subject was suffered from 3 adverse events simultaneously (hoarseness, tremor and palpitation, 5 subjects were only tremor. Of N-group, all 6 subjects were only suffered from tremor. A combination of formoterol/budesonide turbuhaler and a combination of nebulized salbutamol/ipratropium bromide are clinically equivalent for treatment moderate acute asthma. However, nebulized salbutamol/ipratropium bromide had less adverse effects. (Med J Indones 2006; 15:34-42Keywords: phormoterol, budesonide, salbutamol, ipratropium bromide, acute asthma

    Inflammation is an essential component of asthma pathophysiology. While beta(2)-agonists are often used for short-term relief of acute bronchospasm, anti-inflammatory agents are required for the long-term management of chronic inflammation in this disease. Corticosteroids have emerged as the first......-line anti-inflammatory therapy for asthma management. However, in some patients, especially children, the high doses of corticosteroids that may be required to control features of hyperresponsiveness, including exercise-induced asthma, raise safety concerns. Thus, there is a need for complementary anti......-inflammatory, steroid-sparing agents in asthma therapy. Several inflammatory mediators have been targeted in an attempt to thwart this inflammatory process, but so far with little success. The cysteinyl leukotrienes (CysLT), LTC(4), LTD(4), and LTE(4), have been shown to be essential mediators in asthma, making them...

    Heliox, a helium-oxygen gas mixture, has been used for many decades to treat obstructive pulmonary disease. The lower density and higher viscosity of heliox relative to nitrogen-oxygen mixtures can significantly reduce airway resistance when an anatomic upper air-flow obstruction is present and gas flow is turbulent. Clinically, heliox can decrease airway resistance in acute asthma in adults and children and in COPD. Heliox may also enhance the bronchodilating effects of β-agonist administration for acute asthma. Respiratory syndromes caused by coronavirus infections in humans range in severity from the common cold to severe acute respiratory syndrome associated with human coronavirus OC43 and other viral strains. In infants, coronavirus infection can cause bronchitis, bronchiolitis, and pneumonia in variable combinations and can produce enough air-flow obstruction to cause respiratory failure. We describe a case of coronavirus OC43 infection in an infant with severe acute respiratory distress treated with heliox inhalation to avoid intubation. PMID:25118308

  12. Severity assessment of acute pulmonary embolism: evaluation using helical CT

    The objective was to evaluate the helical CT (HCT) criteria that could indicate severe pulmonary embolism (PE). In a retrospective study, 81 patients (mean age 62 years) with clinical suspicion of PE explored by HCT were studied. The patients were separated into three different groups according to clinical severity and treatment decisions: group SPE included patients with severe PE based on clinical data who were treated by fibrinolysis or embolectomy (n=20); group NSPE included patients with non-severe PE who received heparin (n=30); and group WPE included patients without PE (n=31). For each patient we calculated a vascular obstruction index based on the site of obstruction and the degree of occlusion in the pulmonary artery. We noted the HCT signs, i.e., cardiac and pulmonary artery dimensions, that could indicate acute cor pulmonale. According to multivariate analysis, factors significantly correlated with the severity of PE were: the vascular obstruction index (group SPE: 54%; group NSPE: 24%; p<0.001); the maximum minor axis of the left ventricle (group SPE: 30.2 mm; group NSPE: 40.4 mm; p<0.001); the diameter of the central pulmonary artery (group SPE: 32.4 mm; group NSPE: 28.3 mm; p<0.001); the maximum minor axis of the right ventricle (group SPE: 47.5 mm; group NSPE: 42.7 mm; p=0.029); the right ventricle/left ventricle minor axis ratio (group SPE: 1.63; group NSPE: 1.09; p<0.0001). Our data suggest that hemodynamic severity of PE can be assessed on HCT scans by measuring four main criteria: the vascular obstruction index; the minimum diameter of the left ventricle; the RV:LV ratio; and the diameter of the central pulmonary artery.

    2015-01-01

    Full Text Available We report a case of acute promyelocytic leukemia (APL presenting with severely fibrotic marrow. There are four other reports of similar cases in the literature. Our patient was treated with All-Transretinoic Acid- (ATRA- containing induction chemotherapy, followed by consolidation and maintenance therapy. He achieved a complete morphologic remission with adequate count recovery in a timely fashion, and later a molecular remission was documented. The patient remains in molecular remission and demonstrates normal blood counts now more than 4 years after induction. Since the morphological appearance may not be typical and the bone marrow may not yield an aspirate for cytogenetic analysis, awareness of such entity is important to make a correct diagnosis of this potentially curable disease.

  14. Contemporary management of infected necrosis complicating severe acute pancreatitis

    Jamdar, Saurabh; Siriwardena, Ajith K

    2006-01-01

    Pancreatic necrosis complicating severe acute pancreatitis is a challenging scenario in contemporary critical care practice; it requires multidisciplinary care in a setting where there is a relatively limited evidence base to support decision making. This commentary provides a concise overview of current management of patients with infected necrosis, focusing on detection, the role of pharmacologic intervention, and the timing and nature of surgical interventions. Fine-needle aspiration of necrosis remains the mainstay for establishment of infection. Pharmacological intervention includes antibiotic therapy as an adjunct to surgical debridement/drainage and, more recently, drotrecogin alfa. Specific concerns remain regarding the suitability of drotrecogin alfa in this setting. Early surgical intervention is unhelpful; surgery is indicated when there is strong evidence for infection of necrotic tissue, with the current trend being toward 'less drastic' surgical interventions.

    2011-01-01

    A treatment method based on drainage via retroperitoneal laparoscopy was adopted for 15 severe acute pancreatitis (SAP) patients to investigate the feasibility of the method.Ten patients received only drainage via retroperitoneai laparoscopy,four patients received drainage via both retroperitoneal and preperitoneal laparoscopy,and one patient received drainage via conversion to laparotomy.Thirteen patients exhibited a good drainage effect and were successfully cured without any other surgical treatment.Two patients had encapsulated effusions or pancreatic pseudocysts after surgery,but were successfully cured after lavage and B ultrasound-guided percutaneous catheter drainage.SAP treatment via retroperitoneal laparoscopic drainage is an effective surgical method,resulting in minor injury.

  16. Chronic Hepatitis B with Spontaneous Severe Acute Exacerbation

    Wei-Lun Tsai

    2015-11-01

    Full Text Available Chronic hepatitis B virus (HBV infection is a major global health problem with an estimated 400 million HBV carriers worldwide. In the natural history of chronic hepatitis B (CHB, spontaneous acute exacerbation (AE is not uncommon, with a cumulative incidence of 10%–30% every year. While exacerbations can be mild, some patients may develop hepatic decompensation and even die. The underlying pathogenesis is possibly related to the activation of cytotoxic T lymphocyte-mediated immune response against HBV. An upsurge of serum HBV DNA usually precedes the rise of alanine aminotransferase (ALT and bilirubin. Whether antiviral treatment can benefit CHB with severe AE remains controversial, but early nucleos(tide analogues treatment seemed to be associated with an improved outcome. There has been no randomized study that compared the effects of different nucleos(tide analogues (NA in the setting of CHB with severe AE. However, potent NAs with good resistance profiles are recommended. In this review, we summarized current knowledge regarding the natural history, pathogenetic mechanisms, and therapeutic options of CHB with severe AE.

    1998-01-01

    Fifty nine asthmatic children and adolescents, clinically stable, aged 6 to 15 years, 37 boys and 22 girls, from Instituto da Criança do Hospital das Clínicas da FMUSP, were studied from September to November, 1994. The patients were classified by the clinical score of the International Consensus for Asthma Diagnosis and Management. They performed baseline spirometry and peak expiratory flow rates (PEFR), before and after bronchodilator, and measured PEFR three times a day (6 pm, at bedtime and on waking), for one day, at home. Five PEF measurements were made serially and the best readings were considered. Variability of PFE was calculated for 24 hours, as assessed by maximal amplitude. The results were summited to statistical analysis of the Laboratorio de Informática Médica da Faculdade de Medicina da USP. The results of PEFR and it's variability were compared to spirometry, (functional score, FEV1-forced expiratory volume in the first second) and to the clinical score of the International Consensus for Asthma Diagnosis and Management. In case of disagreement between the clinical parameters, the more severe one was chosen. The clinical score classified 20.3% of our patients as mild obstruction, 49.2% as moderate and 30.5% as severely compromised. According to FEV1, 58% of patients were classified as normal while the PEFR and its variability classified as normal 76% and 71%. The PEFR and it's variability in 24 hours, correlated with the VEF1, as gold standard, showed good specificity, 91% and 76% respectively and low sensibility, 44% and 32%. It was detected a low level of agreement between FEV1, PEFR and it's variability in 24 hours, in the clinical severity classification of asthma. The results of this study showed that FEV1 and PEFR had a low level of agreement in the clinical severity classification of asthma and when they were correlated to the clinical score of the International Consensus, they both presented low sensitivity.

    2012-01-01

    Full Text Available Aims and Objectives: To study the incidence, demographic profile, and outcome of patients with severe closed head injuries who develop acute arterial infarcts. Materials and Methods: Patients with severe head injury (Glasgow coma score (GCS ≤8 presenting within 8 h of injury in the Department of Neurosurgery over a period of 5 months were enrolled in the study. Patients with penetrating head injury, infarct due to herniation and iatrogenic arterial injuries were excluded from the study. Only arterial infarcts developing within 8 h of injury were included in the study. A computed tomography (CT head was done on all patients within 8 h of injury and repeated if necessary. Arterial infarct was defined as well-demarcated wedge-shaped hypodensity corresponding to an arterial territory on plain CT of the head. Outcome was assessed using Glasgow outcome score (GOS at 1 month post-injury or at death (whichever came earlier. Results: Forty-four patients of severe head injury were included in the study during the above period. Of these, four patients (9.1% had arterial infarcts on the initial CT scan. The male:female ratio was 1:3. The mean age was 54 years (range 3-85 years. Two patients had infarcts in the middle cerebral artery distribution and two in the superior cerebellar artery distribution. Poor outcome (GOS 1-3 was seen in 100% of the patients with arterial infarct compared to 52.5% (n=21 in patients with severe head injury without arterial infarct. Conclusions: A significant percentage of patients with severe head injury have arterial infarcts on admission, which may imply arterial injury. Our study shows that these patients have a poorer prognosis vis-a-vis patient without these findings.

    2004-01-01

    AIM: To investigate the clinical characteristics and prognostic factors of a consecutive series of patients with severe acute pancreatitis (SAP).METHODS: Clinical data of SAP patients admitted to our hospital from January 2003 to January 2004 were retrospectively reviewed. Collected data included the age, gender, etiology,length of hospitalization, APACHE Ⅱ score at admission,local and organ/systemic complications of the patients.RESULTS: Of the 268 acute pancreatitis patients, 94 developed SAP. The mean age of SAP patients was 52 years, the commonest etiology was cholelithiasis (45.7%), the mean length of hospitalization was 70 d, the mean score of APACHE Ⅱ was 7.7. Fifty-four percent of the patients developed necrosis, 25% abscess, 58% organ/systemic failure. A total of 23.4% (22/94) of the SAP patients died. Respiratory failure was the most common organ clysfunction (90.9%) in deceased SAP patients, followed by cardiovascular failure (86.4%),renal failure (50.0%). In the SAP patients, 90.9% (20/22)developed multiple organ/systemic failures. There were significant differences in age, length of hospitalization,APACHE Ⅱ score and incidences of respiratory failure, renal failure, cardiovascular failure and hematological failure between deceased SAP patients and survived SAP patients.By multivariate logistic regression analysis, independent prognostic factors for mortality were respiratory failure,cardiovascular failure and renal failure.CONCLUSION: SAP patients are characterized by advanced age, high APACHE Ⅱ score, organ failure and their death is mainly due to multiple organ/systemic failures. In patients with SAP, respiratory, cardiovascular and renal failures can predict the fatal outcome and more attention should be paid to their clinical evaluation.

    2006-01-01

    AIM: To investigate the severity of acute pancreatitis (AP) is associated to the intensity of leukocyte activation,inflammatory up-regulation and microcirculatory disruption associated to ischemia-reperfusion injury.Microvascular integrity and inhibition of pro-inflammatory mediators are key-factors in the evolution of AP. Relaxin is an insulin-like hormone that has been attributed vasorelaxant properties via the nitric oxide pathway while behaving as a glucocorticoid receptor agonist.METHODS: AP was induced by the bilio-pancreatic duct-outlet-exclusion closed-duodenal-loops model.Treatment with relaxin was done at different timepoints. Nitric oxide synthase inhibition by L-NAME and glucocorticoid receptor (GR) blockage by mifepristone was considered. AP severity was assessed by biochemical and histopathological analyses.RESULTS: Treatment with relaxin reduced serum amylase, lipase, C-reactive protein, IL-6, IL-10, hsp72,LDH and 8-isoprostane as well as pancreatic and lung myeloperoxidase. Acinar and fat necrosis, hemorrhage and neutrophil infiltrate were also decreased. ATP depletion and ADP/ATP ratio were reduced while caspases 2-3-8 and 9 activities were increased. L-NAME and mifepristone decreased the efficiency of relaxin.CONCLUSION: Relaxin resulted beneficial in the treatment of AP combining the properties of a GR agonist while preserving the microcirculation and favoring apoptosis over necrosis.

    2006-01-01

    @@ Since November 2002, an infectious disease with unknown cause occurred in China and many countries had been involved. Cases were reported in 28 countries and more than 5050 individuals had been infected.1 Lung is the most frequently involved organ and can be fatal in severe cases. At the end of February 2003, it was defined as Severe Acute Respiratory Syndrome (SARS) by World Health Organization. China had a SARS epidemic in the spring of 2003. More than 1000 patients were infected and some patients died of respiratory failure.Finally, a new variant of coronavirus was suspected to be the pathogen although the pathogenesis was still unclear. Since it is a new disease and we have very limited knowledge about its clinical sequela, we followed the survived patients closely in order to understand it in depth. During the follow up, we discovered an interesting patient who was finally diagnosed as fibromyalgia. We report this case herein to share our experience with clinicians who may see patients with SARS or fibromyalgia.

    Full Text Available INTRODUCTION: Asthma is an inflammatory, reversible and progressive disease with episodes of exacerbations. Asthma is now considered as single airway disease and hence comprehensive diagnosis, treatment and follow-up of upper and lower respiratory tract is essential. Both the Nasal and Bronchial mucosa are the elements of united airway disease and Eosinophils measured from this mucosa can be an indirect marker of Airway inflammation in asthma. Eosinophil infiltration is hallmark feature of pathogenesis of asthma which is the trigger for the chronic airway inflammation and these are raised in acute exacerbations. Hence assessing Eosinophil is evidence of serological marker for Airway inflammation (AI. Nasal Smear Eosinophils (NSE is used in asthma with Allergic Rhinitis (AR. This study Using Definition of GINA explores the utility of NSE as marker for management of Asthma. METHODS: In this study 100 patients diagnosed with bronchial asthma attending the outpatient department in KIMS were studied. The severity of asthma was assessed as per FEV1 classification- Adapted from 2007 NHLBI Guidelines for the diagnosis and treatment of Asthma Expert panel Report 3. The Statistical analysis was done with SAS 9.2, SPSS 15.0, Stata 10.1, Med Calc 9.0.1, Systat 12.0 and R environment ver.2.11.1.software. RESULTS: Asthma was more common in Females in this study with M: F ratio of 1.04 and Allergic Rhinitis was found in 55% of Asthmatics. Nasal Eosinophilia was seen in 44% in asthmatic group and 49% in Asthma with Allergic Rhinitis. Absolute Eosinophil count (AEC and Differential count (DC for Eosinophils was almost same in both groups. The Sensitivity of NSE with respect to DC is 70% and in AR group with Asthma and in Asthma group with/without AR it was 38%. Similarly the NSE with respect to AEC was 47% in AR group with Asthma whereas in Asthma group with/without AR it was 38%.

    Full Text Available Objectives: The aim of this study was to investigate the IgE-mediated pathogenesis of severe asthma presented by a patient only after handling shiitake (Lentinus edodes mushrooms (SM. Material and Methods: Skin tests were performed using in-house extracts from mushrooms that the patient usually handled, i.e., shiitake, porcini, oyster and black fungus mushroom varieties. Specific IgE to champignons and various molds were determined. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE immunoblotting was performed to detect IgE-binding components. Four negative controls were included in the study. Results: Skin prick tests performed with in-house mushroom extracts from varieties other than shiitake were completely negative, in contrast to the positive test obtained for shiitake mushrooms. Serum specific IgE levels for common molds and champignons were all negative. SDS-PAGE revealed many protein bands in the four mushroom extracts. Immunoblotting using the patient’s serum showed allergenic bands at about 15 and 24 kDa exclusively for SM that were not shared with negative controls. Another faint band was detectable at approximately 37 kDa for SM and porcini varieties. Conclusions: Here, we present the first European case of SM-induced occupational asthma, a disease more frequently occurring in Asia. Asthma attacks stopped when the patient avoided contact with shiitake mushrooms. No skin reactions and no IgE-binding proteins by immunoblotting were detectable with the other mushrooms tested. The positive skin test with shiitake mushrooms and IgE-binding components in the shiitake extract confirmed the IgE-mediated etiology of the reaction.

    2003-01-01

    Severe acute respiratory syndrome (SARS), also called infectious atypical pneumonia, is an emerging infectious disease caused by a novel variant of coronavirus (SARS associated coronavirus, SARS-CoV). It is mainly characterized by pulmonary infection with a high infectivity and fatality.SARS is swept across almost all the continents of the globe, and has currently involved 33 countries and regions, including the mainland China, Hong Kong, Taiwan, North America and Europe. On June 30, 2003, an acumulative total reached 8450 cases with 810 deaths. SARS epidemic was very rampant in March, April and May 2003 in the mainland of China and Hong Kong. Chinese scientists and healthcare workers cooperated closely with other scientists from all over the world to fight the disease. On April 16, 2003, World Health Organization (WHO) formally declared that SARSCoV was an etiological agent of SARS. Currently, there is no specific and effective therapy and prevention method for SARS. The main treatments include corticosteroid therapy,antiviralagents, anti-infection, mechanical ventilation and isolation. This disease can be prevented and controlled, and it is also curable. Under the endeavor of the Chinese Government, medical staffs and other related professionals,SARS has been under control in China, and Chinese scientists have also made a great contribution to SARS research.Otherstudies in developing new detection assays and therapies, and discovering new drugs and vaccines are in progress. In this paper, we briefly review the current status of SARS in China.

  7. Ischemic penumbra in early stage of severe acute pancreatitis

    We investigated the existence of an ischemic penumbra, which indicates ischemic but still viable lesion, in the early stage of severe acute pancreatitis (SAP). Seventy-one consecutive patients with SAP were enrolled. We divided the pancreas into three regions, the head, body and tail, and measured pancreatic blood flow (FV) and volume (VD) in each region by perfusion CT with one compartment method within three days after the onset of symptoms. Three weeks later, all patients underwent contrast-enhanced CT to diagnose each region for the development of pancreatic necrosis. Of the 227 pancreatic regions from 71 SAP patients, 30 regions were diagnosed as positive for pancreatic necrosis. FV and VD in regions that developed pancreatic necrosis were significantly lower than those in regions without necrosis (35.7±50.7 vs. 197.0±227.6 ml/min, pVDV≥37.5 ml/min and VDVD≥3.4%, 4 (11.7%) developed necrosis. None of 141 regions with FV≥37.5 ml/min and VD≥3.4% developed necrosis. If FV or VD was low, not all regions developed pancreatic necrosis; therefore, we considered that these regions could include zones of ischemic penumbra. (author)

  8. Clinical and radiological analysis of severe acute respiratory syndrome

    Objective: To study the X-ray features of severe acute respiratory syndrome (SARS). Methods: The clinical data and X-ray appearances of 29 cases with SARS were analyzed retrospectively. Results: Epidemic outbreak of SARS has occurred at this area. 29 cases of SARS in this group began with a fever. 15 cases (51.7%) experienced mild respiratory symptoms. In 10 patients (34.5%) the antibacterial medication showed inefficacy before hospitalization. Leucocyte counting was normal in 18 cases (62.1%) and decreased in 11 cases (37.9%). Platelet counting slightly decreased in 7 cases (24.1%). Hepatic function test was abnormal in 16 patients (55.2%), mostly with a decrease of serum enzymology. Obvious abnormalities were seen on the chest films, which were in sharp contrast with the mild clinical respiratory signs. Chest X-ray findings were as follows: Exaggerated and indistinct lung markings with reticular shadow in 7 cases (24.1%), ground-glass opacity in 3 cases (10.4%), small patchy and multi-patchy imaging in 12 cases (41.4%), and large patchy shadow in 7 cases (24.1%). X-ray abnormality was presented later and absorbed slower. Conclusion: SARS carries a variety of X-ray appearances. The combined use of epidemiologic history, clinical situation, laboratory tests, and imaging examinations can make a definite diagnosis

  9. Severe acute respiratory syndrome: vaccine on the way

    ZHANG Ding-mei; WANG Guo-ling; LU Jia-hai

    2005-01-01

    @@ In November 2002, a new disease-severe acute respiratory syndrome, or SARS-first emerged in Guangdong Province, China. Subsequently, it spread to more than 30 countries worldwide.1 The causative agent was identified to be a previously unknown member of the coronaviridae family, and was named SARS coronavirus (SARS-CoV). SARS coronavirus is a large, enveloped, positive-sense RNA virus. The genome is about 30 kb, which is predicted to contain 14 functional open reading frames (ORFs). Two large 5'-terminal ORFs (1a and 1b) encode the polymerases that are required for viral RNA synthesis. The remaining twelve ORFs encode four structural proteins [spike protein (S), envelope protein (E), membrane protein (M) and nucleocapsid protein (N)] and eight accessory proteins.2 Though the SARS-CoV genome is clear, a great deal more work will be required to develop an efficient vaccine and effective drugs. Neutralizing antibodies were detectable in the convalescent sera of SARS patients, and sera from recovered patients could be used to treat newly infected individuals.3 The data suggest that protective humoral immunity is achievable and that vaccines can be developed for prevention of SARS. In this article, we review and discuss progress towards development of a SARS vaccine.

  10. Epidemiology of severe acute respiratory syndrome (SARS): adults and children.

    Severe acute respiratory syndrome (SARS) is a newly described respiratory infection with pandemic potential. The causative agent is a new strain of coronavirus most likely originating from wild animals. This disease first emerged in November 2002 in Guangdong Province, China. Early in the outbreak the infection had been transmitted primarily via household contacts and healthcare settings. In late February 2003 the infection was transmitted to Hong Kong when an infected doctor from the mainland visited there. During his stay in Hong Kong at least 17 guests and visitors were infected at the hotel at which he stayed. By modern day air travel, the infection was rapidly spread to other countries including Vietnam, Singapore and Canada by these infected guests. With the implementation of effective control strategies including early isolation of suspected cases, strict infection control measures in the hospital setting, meticulous contact tracing and quarantine, the outbreak was finally brought under control by July 2003. In addition, there were another two events of SARS in China between the end of December 2003 and January 2004 and from March to May 2004; both were readily controlled without significant patient spread.

    Synchrotron inline phase-contrast computed tomography in combination with single-distance phase retrieval enables quantification of morphological alterations in lungs of mice with mild and severe experimental allergic airways disease in comparison with healthy controls. Lung imaging in mouse disease models is crucial for the assessment of the severity of airway disease but remains challenging due to the small size and the high porosity of the organ. Synchrotron inline free-propagation phase-contrast computed tomography (CT) with its intrinsic high soft-tissue contrast provides the necessary sensitivity and spatial resolution to analyse the mouse lung structure in great detail. Here, this technique has been applied in combination with single-distance phase retrieval to quantify alterations of the lung structure in experimental asthma mouse models of different severity. In order to mimic an in vivo situation as close as possible, the lungs were inflated with air at a constant physiological pressure. Entire mice were embedded in agarose gel and imaged using inline free-propagation phase-contrast CT at the SYRMEP beamline (Synchrotron Light Source, ‘Elettra’, Trieste, Italy). The quantification of the obtained phase-contrast CT data sets revealed an increasing lung soft-tissue content in mice correlating with the degree of the severity of experimental allergic airways disease. In this way, it was possible to successfully discriminate between healthy controls and mice with either mild or severe allergic airway disease. It is believed that this approach may have the potential to evaluate the efficacy of novel therapeutic strategies that target airway remodelling processes in asthma.

    Background Several coronaviruses establish persistent infections in vitro and in vivo, however it is unknown whether persistence is a feature of the severe acute respiratory syndorme coronavirus (SARS-CoV) life cycle. This study was conducted to investigate viral persistence.Methods We inoculated confluent monolayers of Vero cells with SARS-CoV at a multiplicity of infection of 0.1 TCID50 and passaged the remaining cells every 4 to 8 days for a total of 11 passages. Virus was titrated at each passage by limited dilution assay and nucleocapsid antigen was detected by Western blot and immunofluoresence assays. The presence of viral particles in passage 11 cells was assessed by electron microscopy. Changes in viral genomic sequences during persistent infection were examined by DNA sequencing. Results Cytopathic effect was extensive after initial inoculation but diminished with serial passages. Infectious virus was detected after each passage and viral growth curves were identical for parental virus stock and virus obtained from passage 11 cells. Nucleocapsid antigen was detected in the majority of cells after initial inoculation but in only 10%-40% of cells at passages 2-11. Electron microscopy confirmed the presence of viral particles in passage 11 cells. Sequence analysis at passage 11 revealed fixed mutations in the spike (S) gene and ORFs 7a-8b but not in the nucleocapsid (N) gene. Conclusions SARS-CoV can establish a persistent infection in vitro. The mechanism for viral persistence is consistent with the formation of a carrier culture whereby a limited number of cells are infected with each round of virus replication and release. Persistence is associated with selected mutations in the SARS-CoV genome. This model may provide insight into SARS-related lung pathology and mechanisms by which humans and animals can serve as reservoirs for infection.

  14. The severe acute respiratory syndrome epidemic in mainland China dissected

    Full Text Available This paper provides a review of a recently published series of studies that give a detailed and comprehensive documentation of the severe acute respiratory syndrome (SARS epidemic in mainland China, which severely struck the country in the spring of 2003. The epidemic spanned a large geographical extent but clustered in two areas: first in Guangdong Province, and about 3 months later in Beijing with its surrounding areas. Reanalysis of all available epidemiological data resulted in a total of 5327 probable cases of SARS, of whom 343 died. The resulting case fatality ratio (CFR of 6.4% was less than half of that in other SARS-affected countries or areas, and this difference could only partly be explained by younger age of patients and higher number of community acquired infections. Analysis of the impact of interventions demonstrated that strong political commitment and a centrally coordinated response was the most important factor to control SARS in mainland China, whereas the most stringent control measures were all initiated when the epidemic was already dying down. The long-term economic consequence of the epidemic was limited, much consumption was merely postponed, but for Beijing irrecoverable losses to the tourist sector were considerable. An important finding from a cohort study was that many former SARS patients currently suffer from avascular osteo­necrosis, as a consequence of the treatment with corticosteroids during their infection. The SARS epidemic provided valuable information and lessons relevant in controlling outbreaks of newly emerging infectious diseases, and has led to fundamental reforms of the Chinese health system. In particular, a comprehensive nation-wide internet-based disease reporting system was established.

    2012-01-01

    Full Text Available Introduction. Caffeine is indicated in the treatment of migraine headaches, as well as neonatal apnea and bradycardia syndrome. In mild poisoning, the most prevalent symptoms are nausea, vomiting, diarrhea, tremor, anxiety and headache. In more severe cases, symptoms consist of heart rythym abnormalities, myocardial infarction and seizures. Due to its common lipolytic effect, caffeine is used in mesotherapy, usually in combination with drugs of similar effect. We presented a patient with acute iatrogenic caffeine poisoning. Case report. A 51-year-old woman, with preexisting hypertension and hypertensive cardiomyopathy was subjected to cosmetic treatment in order to remove fat by intradermal caffeine injections. During the treatment the patient felt sickness, an urge to vomit, and a pronounced deterioration of general condition. Upon examination, the patient exhibited somnolence, hypotension and nonsustained ventricular tachycardia, which was sufficient enough evidence for further hospitalization. On admission to the intensive care unit the patient was anxious with increased heart rate, normotensive, with cold, damp skin, and visible traces of injection sites with surrounding hematomas on the anterior abdominal wall. Paroxysmal supraventricular tachycardia (PSVT on electrocardiographic monitoring was found. The laboratory analysis determined a lowered potassium level of 2.1 mmol/L (normal range 3,5 - 5.2 mmol/L, and a toxicological analysis (liquid chromatography with ultraviolet detection proved a toxic concentration of caffeine in plasma - 85.03 mg/L (toxic concentration over 25 mg/L. On application of intensive therapy, antiarrhythmics, and substitution of potassium, as well as both symptomatic and supportive therapy, there was a significant recovery. The patient was discharged without any sequele within four days. Conclusion. A presented rare iatrogenic acute caffeine poisoning occured due to massive absorption of caffeine from the

    2014-01-01

    Background The controversy on the treatment strategy for severe acute pancreatitis (SAP) has never stopped for the past century.Even now surgical procedures play a decisive role in the treatment of SAP,especially in managing the related complications,but the rational indications,timing,and approaches of surgical intervention for SAP are still inconclusive.Methods Clinical data of 308 SAP patients recruited during January 2000-January 2013,including 96 conservatively treated cases plus 212 surgically intervened cases,were comparatively analyzed.Based on the initial surgical intervention time,the surgical intervention group was split into two:early intervention group (within 2 weeks) 103 cases,and late intervention group (after 2 weeks) 109 cases.Results In the conservative treatment group,the cure rate was 82.29% (79/96),the death rate was 13.54% (13/96),and 4 cases self-discharged,while in the surgical intervention group,the cure rate was 84.43% (179/212) and the death rate was 10.85% (23/212) with 10 cases self-discharged.The difference was of no statistical significance between these two groups (P >0.05).In surgical intervention group,the death rate 15.53% (16/103) in the early surgical intervention group was higher than that of late surgical intervention group 6.42% (7/109),and the difference was statistically significant (P <0.05).Conclusions Both conservative treatment and surgical intervention play important roles in the treatment of SAP,and the indication,timing,and procedure should be strictly followed.Surgery earlier than 2 weeks after onset of the disease is not recommended in patients with necrotizing pancreatitis only when there are specific indications,such as multiple organ failure,which does not improve despite active treatment,and in those who develop abdominal compartment syndrome.

    AIM: To summarize clinical features of probable severe acute respiratory syndrome (SARS) in Beijing.METHODS: Retrospective cases involving 801 patients admitted to hospitals in Beijing between March and June 2003, with a diagnosis of probable SARS, moderate type.The series of clinical manifestation, laboratory and radiograph data obtained from 801 cases were analyzed. RESULTS: One to three days after the onset of SARS, the major clinical symptoms were fever (in 88.14% of patients), fatigue, headache, myalgia, arthralgia (25-36%), etc. The counts of WBC (in 22.56% of patients) lymphocyte (70.25%)and CD3, CD4, CD8 positive T cells (70%) decreased. From 4-7 d, the unspecific symptoms became weak; however, the rates of low respiratory tract symptoms, such as cough (24.18%), sputum production (14.26%), chest distress (21.04%) and shortness of breath (9.23%) increased, so did the abnormal rates on chest radiograph or CT. The low counts of WBC, lymphocyte and CD3, CD4, CD8 positiveT cells touched bottom. From 8 to 16 d, the patients presented progressive cough (29.96%), sputum production (13.09%), chest distress (29.96%) and shortness of breath (35.34%). All patients had infiltrates on chest radiograph or CT, some even with multi-infiltrates. Two weeks later, patients' respiratory symptoms started to alleviate, the infiltrates on the lung began to absorb gradually, the counts of WBC, lymphocyte and CD3, CD4, CD8 positive T cells were restored to normality.CONCLUSION: The data reported here provide evidence that the course of SARS could be divided into four stages, namely the initial stage, progressive stage, fastigium and convalescent stage.

  20. Acute effects of urban ambient air pollution on respiratory symptoms, asthma medication use, and doctor visits for asthma in a cohort of Australian children

    We enrolled a cohort of primary school children with a history of wheeze (n=148) in an 11-month longitudinal study to examine the relationship between ambient air pollution and respiratory morbidity. We obtained daily air pollution (ozone, particulate matter less than 10 μm, and nitrogen dioxide), meteorological, and pollen data. One hundred twenty-five children remained in the final analysis. We used logistic regression models to determine associations between air pollution and respiratory symptoms, asthma medication use, and doctor visits for asthma. There were no associations between ambient ozone concentrations and respiratory symptoms, asthma medication use, and doctor visits for asthma. There was, however, an association between PM10 concentrations and doctor visits for asthma (RR=1.11, 95% CI=1.04-1.19) and between NO2 concentration and wet cough (RR=1.05, 95% CI=1.003-1.10) in single-pollutant models. The associations remained significant in multipollutant models. There was no consistent evidence that children with wheeze, positive histamine challenge, and doctor diagnosis of asthma reacted differently to air pollution from children with wheeze and doctor diagnosis of asthma and children with wheeze only. There were significant associations between PM10 levels and doctor visits for asthma and an association between NO2 levels and the prevalence of wet cough. We were, however, unable to demonstrate that current levels of ambient air pollution in western Sydney have a coherent range of adverse health effects on children with a history of wheezing

    1992-01-01

    Between 1984 and 1986 six patients with acute respiratory failure (requiring ventilation for at least 3 days) complicating acute pancreatitis were managed on the intensive care unit (median ventilation period 6 days; range 3-41 days). Between 1987 and 1989 nine similar patients were managed (median ventilation period 35 days, range 4-69 days), and a regimen of enteral tobramycin, polymyxin and amphotericin to selectively decontaminate the digestive tract (SDD) was introduced.

  2. Compared with parenteral nutrition, enteral feeding attenuates the acute phase response and improves disease severity in acute pancreatitis

    Windsor, A; Kanwar, S; Li, A.; Barnes, E.; Guthrie, J; Spark, J; Welsh, F.; Guillou, P; Reynolds, J

    1998-01-01

    Background—In patients with major trauma and burns, total enteral nutrition (TEN) significantly decreases the acute phase response and incidence of septic complications when compared with total parenteral nutrition (TPN). Poor outcome in acute pancreatitis is associated with a high incidence of systemic inflammatory response syndrome (SIRS) and sepsis. 
Aims—To determine whether TEN can attenuate the acute phase response and improve clinical disease severity in patients with ac...

Material and methods: In a retrospective design, we audited the hospital records of all patients aged 18-40 years admitted to five Danish university hospitals with an acute exacerbation of asthma in 2004. Results: We found records covering 323 asthmatic patients (186 women). Before...... forced expiratory volume in first second) was measured in 60% on admission, in 58% on discharge and in 47% on both occasions (P < 0.01). Temperature, heart rate and oxygen saturation were measured in 231 of the patients (72%), but the respiratory frequency rate was measured in only 16% of the patients......, with some differences between the five hospitals. On discharge, 50% were treated with systemic steroids, and a further 20% had ICS prescribed (P < 0.01, admission vs discharge). In 21% of the cases, inadequate treatment was identified as the most likely reason for their ER visit/admission to a hospital...

  7. The absence of exanthema is related with death and illness severity in acute enterovirus infection

    Hong-Tao Zhou

    2014-11-01

    Conclusions: A considerable proportion of children with an acute enterovirus infection in Guangdong Province, China during 2009–2012 presented no exanthema, and the absence of exanthema was found to be related to death and illness severity for these acute enterovirus infections. Clinicians in China should consider enterovirus as the possible pathogen when treating children with an acute pathogen infection without exanthema.

    2007-01-01

    AIM: To determine the effect of pioglitazone, a specific peroxisome proliferator-activated receptor-γ (PPARγ)ligand, on development of severe acute pancreatitis (SAP) and expression of nuclear factor-kappa B (NF-κB)and intercellular adhesion molecule-1 (ICAM-1) in the pancreas.METHODS: Male Sprague-Dawley (SD) rats (160-200 g)were randomly allocated into three groups (n = 18in each group): severe acute pancreatitis group,pioglitazone group, sham group. SAP was induced by retrograde infusion of 1 mL/kg body weight 5% sodium taurocholate (STC) into the biliopancreatic duct of male SD rats. Pioglitazone was injected intraperitoneally two hours piror to STC infusion. Blood and ascites were obtained for detecting amylase and ascitic capacity. Pancreatic wet/dry weight ratio, expression of NF-κB and ICAM-1 in pancreatic tissues were detected by immunohistochemical staining. Pancreatic tissue samples were stained with hematoxylin and eosin (HE)for routine optic microscopy.RESULTS: Sham group displayed normal pancreatic structure. SAP group showed diffuse hemorrhage,necrosis and severe edema in focal areas of pancreas.There was obvious adipo-saponification in abdominal cavity. Characteristics such as pancreatic hemorrhage,necrosis, severe edema and adipo-saponification were found in pioglitazone group, but the levels of those injuries were lower in pioglitazone group than those in SAP group. The wet/dry pancreatic weight ratio,ascetic capacity, serum and ascitic activities of anylase in the SAP group were significantly higher than those in the sham group and pioglitazone group respectively (6969.50 ± 1368.99 vs 2104.67 ± 377.16, 3.99 ± 1.22 vs 2.48 ± 0.74, P < 0.01 or P < 0.05). According to Kusske criteria, the pancreatic histologic score showed that interstitial edema, inflammatory infiltration,parenchyma necrosis and parenchyma hommorrhage in SAP group significantly differed from those in the sham group and pioglitazone group (7.17 ± 1.83 vs 0.50 ±0.55, 7

  9. An analysis of the utilisation and expenditure of medicines dispensed for the management of severe asthma.

    2009-03-01

    There are approximately 6,300 people in Ireland with a diagnosis of Chronic Obstructive Pulmonary Disease (COPD) and with a fast growing elderly population the incidence of COPD is likely to increase. This study examines the prescribing patterns of medicines dispensed for the management Asthma\\/COPD in patients over the age of 35 years using the HSE-Primary Care Reimbursement Services (PCRS) prescribing databases. The HSE-PCRS pharmacy claims data, which covers all those over 70 years of age and means tested for those less than 70 years, was analysed for the years 2005\\/2006. Approximately 26,548 (17.9%) of patients who were prescribed a respiratory drug received inhaled short-acting beta2 agonists in combination with a regular standard-dose inhaled corticosteroid. A further 5,044 (3.4%) were also prescribed a regular inhaled long-acting beta2 agonist (salmeterol or formoterol). A total of 2506 patients (6.2%) on combination therapy were co-prescribed four different anti-asthmatic treatments inclusive of oral prednisolone. A small proportion of the patients prescribed a respiratory drug were co-prescribed nicotine replacement therapy (n = 5177, 3.5%). In total there were 9,728 (6.2%) patients prescribed a mucolytic drug in combination with a respiratory drug and the rate of co-prescribing with antibiotics was 22%. COPD is a debilitating disease that is primarily caused by smoking and is therefore largely preventable. The HSE-PCRS pharmacy claims data is a valuable tool for helping to assess the burden of this disease in the Irish context.

  10. Methomyl-Induced Severe Acute Pancreatitis: Possible Etiological Association

    Ioannides M

    2005-03-01

    Full Text Available CONTEXT: N-methyl carbamate insecticides are widely used in homes, gardens and agriculture. They share the capacity to inhibit cholinesterase enzymes with organophosphates and therefore share similar symptomatology during acute and chronic exposures. One of the serious effects of organophosphate and carbamate intoxication is the development of acute pancreatitis and subsequent intrapancreatic fluid formation. CASE REPORT: An 18-year old Caucasian man was admitted to our Intensive Care Unit with cholinergic crisis symptomatology, after the ingestion of an unknown amount of a carbamate insecticide (methomyl. Pseudocholinesterase levels were 2 kU/L on the day of admission (reference range: 5.4-13.2 kU/L. Two days after admission, an abdominal CT scan revealed blurring of the peripancreatic fat planes, inflammation and swelling of the pancreas, and a substantial amount of ascitic fluid in the left anterior pararenal space and pelvis. Paracentesis and analysis of the ascitic fluid demonstrated findings diagnostic of pancreatic ascites. There had been no other evident predisposing factors for acute pancreatitis, other than methomyl intoxication. Eleven days after admission, pseudocholinesterase levels returned to normal, while a new abdominal CT scan revealed the formation of intrapancreatic fluid collection. The patient was discharged in good physical condition two weeks after admission. A follow up abdominal CT scan performed one month later showed a significant reduction in the size of the intrapancreatic fluid. DISCUSSION: Acute pancreatitis is not uncommon after organophosphate intoxication and carbamates share the same risk as organophosphorus pesticides. The development of acute pancreatitis and subsequent intrapancreatic fluid collection after methomyl intoxication has not previously been reported. This is the first case reported of acute pancreatitis and pancreatic ascite formation after anticholinesterase insecticide ingestion.

  11. Severe acute respiratory syndrome: clinical and laboratory manifestations.

    Lam, Christopher W K; Chan, Michael H M; Wong, Chun K

    2004-05-01

    Severe acute respiratory syndrome (SARS) is a recently emerged infectious disease with significant morbidity and mortality. An epidemic in 2003 affected 8,098 patients in 29 countries with 774 deaths. The aetiological agent is a new coronavirus spread by droplet transmission. Clinical and general laboratory manifestations included fever, chills, rigor, myalgia, malaise, diarrhoea, cough, dyspnoea, pneumonia, lymphopenia, neutrophilia, thrombocytopenia, and elevated serum lactate dehydrogenase (LD), alanine aminotransferase (ALT) and creatine kinase (CK) activities. Treatment has been empirical; initial potent antibiotic cover, followed by simultaneous ribavirin and corticosteroids, with or without pulse high-dose methylprednisolone, have been used. The postulated disease progression comprises (1) active viral infection, (2) hyperactive immune response, and (3) recovery or pulmonary destruction and death. We investigated serum LD isoenzymes and blood lymphocyte subsets of SARS patients, and found LD1 activity as the best biochemical prognostic indicator for death, while CD3+, CD4+, CD8+ and natural killer cell counts were promising predictors for intensive care unit (ICU) admission. Plasma cytokine and chemokine profiles showed markedly elevated Th1 cytokine interferon (IFN)-gamma, inflammatory cytokines interleukin (IL)-1beta, IL-6 and IL-12, neutrophil chemokine IL-8, monocyte chemoattractant protein-1 (MCP-1), and Th1 chemokine IFN-gamma-inducible protein-10 (IP-10) for at least two weeks after disease onset, but there was no significant elevation of inflammatory cytokine tumor necrosis factor (TNF)-alpha and anti-inflammatory cytokine IL-10. Corticosteroid reduced IL-8, MCP-1 and IP-10 concentrations from 5-8 days after treatment. Measurement of biochemical markers of bone metabolism demonstrated significant but transient increase in bone resorption from Day 28-44 after onset of fever, when pulse steroid was most frequently given. With tapering down of steroid

    2016-01-01

    Objective Severe acute malnutrition (SAM) is a major cause of mortality in children under 5 years and is associated with hepatic steatosis. Bile acids are synthesized in the liver and participate in dietary fat digestion, regulation of energy expenditure, and immune responses. The aim of this work was to investigate whether SAM is associated with clinically relevant changes in bile acid homeostasis. Design An initial discovery cohort with 5 healthy controls and 22 SAM-patients was used to identify altered bile acid homeostasis. A follow up cohort of 40 SAM-patients were then studied on admission and 3 days after clinical stabilization to assess recovery in bile acid metabolism. Recruited children were 6–60 months old and admitted for SAM in Malawi. Clinical characteristics, feces and blood were collected on admission and prior to discharge. Bile acids, 7α-hydroxy-4-cholesten-3-one (C4) and FGF-19 were quantified. Results On admission, total serum bile acids were higher in children with SAM than in healthy controls and glycine-conjugates accounted for most of this accumulation with median and interquartile range (IQR) of 24.6 μmol/L [8.6–47.7] compared to 1.9 μmol/L [1.7–3.3] (p = 0.01) in controls. Total serum bile acid concentrations did not decrease prior to discharge. On admission, fecal conjugated bile acids were lower and secondary bile acids higher at admission compared to pre- discharge, suggesting increased bacterial conversion. FGF19 (Fibroblast growth factor 19), a marker of intestinal bile acid signaling, was higher on admission and was associated with decreased C4 concentrations as a marker of bile acid synthesis. Upon recovery, fecal calprotectin, a marker of intestinal inflammation, was lower. Conclusion SAM is associated with increased serum bile acid levels despite reduced synthesis rates. In SAM, there tends to be increased deconjugation of bile acids and conversion from primary to secondary bile acids, which may contribute to the

  13. A large volume of visceral adipose tissue leads to severe acute pancreatitis

    Obesity plays an important role in acute pancreatitis. Assuming that the volume of visceral adipose tissue (VAT) directly influences the severity of acute pancreatitis, we investigated the relationship between VAT and acute pancreatitis. Data were collected consecutively from 124 patients who were diagnosed with acute pancreatitis. Body mass index (BMI) was calculated from the database. Computed tomography was performed in all patients, and VAT, subcutaneous adipose tissue (SAT), and waist circumference (WC) were measured at the level of the intervertebral disk between L2 and L3. Atlanta criteria were adopted to define severe acute pancreatitis. Clinical courses were investigated, and the Ranson and acute physiology and chronic health evaluation II (APACHE II) scores were calculated for all patients. Forty-eight patients had severe acute pancreatitis (38.7%), and 76 were mild cases. BMI, VAT, SAT, and WC were correlated with the severity of acute pancreatitis in a univariate analysis, but only VAT had a strong correlation with severe acute pancreatitis in the multivariate analysis. In a trend analysis, not only severity but also the presence of pseudocysts (local complication) and prognostic factors (Ranson and APACHE II scores) were significantly related to VAT volume. In particular, the presence of a pancreatic pseudocyst was strongly related to VAT volume (p<0.001). In acute pancreatitis, peripancreatic VAT has a stronger correlation with severe acute pancreatitis than BMI or WC. VAT volume is strongly correlated with the formation of a pseudocyst and with systemic inflammatory response syndrome in patients with acute pancreatitis and high VAT volume may lead to severe acute pancreatitis.

  14. Early Treatment of Severe Acute Respiratory Distress Syndrome.

    Przybysz, Thomas M; Heffner, Alan C

    2016-02-01

    Acute respiratory distress syndrome (ARDS) is defined by acute diffuse inflammatory lung injury invoked by a variety of systemic or pulmonary insults. Despite medical progress in management, mortality remains 27% to 45%. Patients with ARDS should be managed with low tidal volume ventilation. Permissive hypercapnea is well tolerated. Conservative fluid strategy can reduce ventilator and hospital days in patients without shock. Prone positioning and neuromuscular blockers reduce mortality in some patients. Early management of ARDS is relevant to emergency medicine. Identifying ARDS patients who should be transferred to an extracorporeal membrane oxygenation center is an important task for emergency providers. PMID:26614238

  17. Six-minute walk test and respiratory muscle strength in patients with uncontrolled severe asthma: a pilot study

    Luiz Fernando Ferreira Pereira

    2015-06-01

    Full Text Available OBJECTIVE: To evaluate respiratory muscle strength and six-minute walk test (6MWT variables in patients with uncontrolled severe asthma (UCSA. METHODS: This was a cross-sectional study involving UCSA patients followed at a university hospital. The patients underwent 6MWT, spirometry, and measurements of respiratory muscle strength, as well as completing the Asthma Control Test (ACT. The Mann-Whitney test was used in order to analyze 6MWT variables, whereas the Kruskal-Wallis test was used to determine whether there was an association between the use of oral corticosteroids and respiratory muscle strength. RESULTS: We included 25 patients. Mean FEV1 was 58.8 ± 21.8% of predicted, and mean ACT score was 14.0 ± 3.9 points. No significant difference was found between the median six-minute walk distance recorded for the UCSA patients and that predicted for healthy Brazilians (512 m and 534 m, respectively; p = 0.14. During the 6MWT, there was no significant drop in SpO2. Mean MIP and MEP were normal (72.9 ± 15.2% and 67.6 ± 22.2%, respectively. Comparing the patients treated with at least four courses of oral corticosteroids per year and those treated with three or fewer, we found no significant differences in MIP (p = 0.15 or MEP (p = 0.45. CONCLUSIONS: Our findings suggest that UCSA patients are similar to normal subjects in terms of 6MWT variables and respiratory muscle strength. The use of oral corticosteroids has no apparent impact on respiratory muscle strength.

  18. Clinical significance of computed tomography on management for severe acute pancreatitis

    We studied whether CT findings would be useful for the judgement of severity and treatment of acute pancreatitis in eight patients who had been diagnosed as having acute severe pancreatitis CT findings objectively revealed where and to what extent such inflammatory reactions of acute pancreatitis as massive retroperitoneal fluid collection and ascites appeared. Those results agreed to abdominal physical findings including Blumberg's sign, muscular defense, paralytic ileus and ascites. When pancreatic fluid collection is prominent, early surgical therapy was effective. (author)

    Except for FVC which had a significant correlation with BMI, other studied indices yielded no significant results, which calls for more extensive studies with larger populations. Considering the fact that mild asthma is less common in obese patients, better weight control in asthmatic patients can promote their quality of life and make asthma management more effective.

  20. Diagnosis of acute necrotizing pancreatitis and acute hemorrhagic pancreatitis in 5 severe acute pancreatitis by plain computed tomography

    The diagnosis of acute pancreatitis is still mainly based on the clinical signs and symptoms of patients. In a prospective study of 64 patients with acute pancreatitis, computed tomography (CT) findings were correlated with the clinical types of acute pancreatitis. We were able to correctly diagnose 3 acute necrotizing pancreatitis with autopsy and 2 acute hemorrhagic pancreatitis by plain CT about 48 hours after onset. At present, CT about 48 hours after onset seems to be the most accurate method for the early detection of necrotizing, hemorrhagic and edematous forms of acute pancreatitis. (author)

  5. Valuing the Economic Costs of Allergic Rhinitis, Acute Bronchitis, and Asthma from Exposure to Indoor Dampness and Mold in the US.

    Mudarri, David H

    2016-01-01

    Two foundational methods for estimating the total economic burden of disease are cost of illness (COI) and willingness to pay (WTP). WTP measures the full cost to society, but WTP estimates are difficult to compute and rarely available. COI methods are more often used but less likely to reflect full costs. This paper attempts to estimate the full economic cost (2014$) of illnesses resulting from exposure to dampness and mold using COI methods and WTP where the data is available. A limited sensitivity analysis of alternative methods and assumptions demonstrates a wide potential range of estimates. In the final estimates, the total annual cost to society attributable to dampness and mold is estimated to be $3.7 (2.3-4.7) billion for allergic rhinitis, $1.9 (1.1-2.3) billion for acute bronchitis, $15.1 (9.4-20.6) billion for asthma morbidity, and $1.7 (0.4-4.5) billion for asthma mortality. The corresponding costs from all causes, not limited to dampness and mold, using the same approach would be $24.8 billion for allergic rhinitis, $13.5 billion for acute bronchitis, $94.5 billion for asthma morbidity, and $10.8 billion for asthma mortality.

  11. Asthma and pregnancy.

    Vatti, Rani Reddy; Teuber, Suzanne S

    2012-08-01

    Asthma is probably the most common serious medical disorder that may complicate pregnancy. A third of pregnant women with asthma will experience worsening of their symptoms, a third will see improvement of their symptoms and a third will see no change. The primary goal is to maintain optimal control of asthma for maternal health and well-being as well as fetal maturation. Vital patient education should cover the use of controller medication, avoidance of asthma triggers and early treatment of asthma exacerbations. Proper asthma management should ideally be started in the preconception period. Since smoking is probably the most modifiable risk factor of asthma, pregnant woman should avoid active and passive smoking. Acute asthma exacerbation during the first trimester is associated with an increased risk of congenital malformations. Poorly controlled asthma is associated with low birth weight, preeclampsia, and preterm birth. Medications used for asthma control in the non-pregnant population are generally the same in pregnancy with a few exceptions. Inhaled corticosteroids (ICS) are the preferred controller therapy. Budesonide is the preferred ICS. Long-acting B-agonists (LABA) are the preferred add-on therapy to medium to high dose ICS. Major triggers for asthma exacerbations during pregnancy are viral infections and ICS nonadherence. PMID:21858482

  12. Comparing the efficacy and safety of two regimens of sequential systemic corticosteroids in the treatment of acute exacerbation of bronchial asthma

    Full Text Available Background : Corticosteroids are commonly used in the management of acute asthma. However, studies comparing various steroids in the management of acute asthma are lacking. Objective : To compare the efficacy and safety of two treatment regimens - intravenous (IV methylprednisolone (MP followed by oral MP and IV hydrocortisone (HC followed by oral prednisolone in acute bronchial asthma patients. Materials and Methods : This was a randomized, prospective study performed in the emergency department (ED of a tertiary care hospital in North India. A total of 94 patients with acute asthma were randomly allocated to either of the two treatment groups: Group A (n = 49 or Group B (n = 45. Patients in Group A were administered HC 200 mg IV 6-hourly until discharge from the ED, followed by oral prednisolone 0.75 mg/kg daily for 2 weeks. Patients in Group B were administered MP 125 mg IV bolus, followed by 40 mg MP IV 6-hourly until discharge, and then oral MP 0.6 mg/kg daily for 2 weeks. All clinical variables, peak expiratory flow (PEF and forced expiratory volume in one second (FEV 1 were assessed at baseline, at 1, 3 and 6 h and at every 6 h thereafter until discharge from the ED. The patients were followed-up after 2 weeks of discharge. The response to treatment was assessed by clinical and spirometric evaluation. Independent t-tests and chi-square tests were used to compare the two treatment regimens. Results : The baseline characteristics were comparable in the two groups. There was a significant improvement in PEF and FEV 1 within the groups at 2 weeks of treatment when compared to the baseline. At 2 weeks of follow-up, Group B showed significant improvement over Group A in PEF (P < 0.0001, FEV 1 (P < 0.0001 and asthma score (P = 0.034. There was a significant increase in the blood sugar value at 2 weeks in both the groups. However, the increase was greater in Group A as compared to Group B (P < 0.0001.

    2011-06-01

    Full Text Available Abstract Background This study had two principal objectives: (i to investigate the relationship between asthma severity and proximity to major roadways in Perth, Western Australia; (ii to demonstrate a more accurate method of exposure assessment for traffic pollutants using an innovative GIS-based measure that fully integrates all traffic densities around subject residences. Methods We conducted a spatial case-control study, in which 'cases' were defined as individuals aged under 19 years of age with more severe asthma (defined here as two or more emergency department contacts with asthma in a defined 5-year period versus age- and gender-matched 'controls' with less severe asthma (defined here as one emergency department contact for asthma. Traffic exposures were measured using a GIS-based approach to determine the lengths of the roads falling within a buffer area, and then multiplying them by their respective traffic counts. Results We examined the spatial relationship between emergency department contacts for asthma at three different buffer sizes: 50 metres, 100 metres and 150 metres. No effect was noted for the 50 metre buffer (OR = 1.07; 95% CI: 0.91-1.26, but elevated odds ratios were observed with for crude (unadjusted estimates OR = 1.21 (95% CI: 1.00-1.46 for 100 metre buffers and OR = 1.25 (95% CI: 1.02-1.54 for 150 metre buffers. For adjusted risk estimates, only the 150 metre buffer yielded a statistically significant finding (OR = 1.24; 95% CI:1.00-1.52. Conclusions Our study revealed a significant 24% increase in the risk of experiencing multiple emergency department contacts for asthma for every log-unit of traffic exposure. This study provides support for the hypothesis that traffic related air pollution increases the frequency of health service contacts for asthma. This study used advanced GIS techniques to establish traffic-weighted buffer zones around the geocoded residential location of subjects to provide an accurate

    Full Text Available Acute post-streptococcal glomerulonephritis (APSGN is very rare below the age of two years. We report a 14-month-old girl who presented with frank hematuria and nephrotic syndrome following group A streptococcal pharyngitis (GAS, which was confirmed by laboratory investigations. The patient underwent a renal biopsy to confirm the diagnosis and was treated with prednisolone. The proteinuria and hematuria resolved completely in eight weeks. Our case demonstrates that APSGN should be considered in evaluating hematuria and nephrotic syndrome in infants and children below two years of age.

    Granulomatous interstitial nephritis (GIN) is an uncommon cause of renal failure, which may be caused by drugs. Levetiracetam is an increasingly used anti-epileptic medication that is not known to cause renal toxicity in adults. To our knowledge, levetiracetam has not previously been reported as a cause of GIN. We report the case of a 69-year-old woman who developed haemodialysis-requiring acute renal failure after commencement of treatment with levetiracetam, which was shown to be GIN by renal biopsy. She made a complete recovery with cessation of levetiracetam and treatment with steroids. PMID:26069773

  19. Pulmonary vasculature and critical asthma syndromes: a comprehensive review.

    Avdalovic, Mark

    2015-02-01

    One of the important factors and consequences in persistent asthma is the change in the vasculature of the airways and lung parenchyma. These changes could contribute to worsening asthma control and predispose asthmatics to critical asthma syndromes. For many years, the contribution of vasculature to severe asthma was limited to discussion of small and medium vessel vasculitis commonly referred to as Churg-Strauss syndrome. This comprehensive review will explore the known mechanisms that are associated with remodeling of the vasculature in a variety of critical asthma presentations. Inflammation of pulmonary and bronchial small blood vessels may contribute significantly but silently to asthma pathobiology. Inflammation in the vasculature of the lung parenchyma can decrease lung capacity while inflammation in airway vasculature can decrease airflow. This review will provide a modern perspective on Churg-Strauss syndromes with a focus on phenotyping, mechanism, and ultimately modern therapeutic approaches. Vascular remodeling and airway remodeling are not mutually exclusive concepts in understanding the progression of asthma and frequency of acute exacerbations. Furthermore, the contribution of vascular leak, particularly in the parenchymal vasculature, has become an increasingly recognized component of certain presentations of poorly controlled, severe persistent asthmatic and during exacerbations. We highlight how these mechanisms can contribute to some the severe presentations of influenza infection in patients with a history of asthma. The ultimate aim of this review is to summarize the current literature concerning vasculitis and the contribution of airway and parenchymal vascular remodeling to presentation of persistent asthma and its consequences during acute exacerbations and critical asthma syndromes.

The primary outcome was FEV1 (% predicted in the two groups at 1, 5, 15, 30, 60 min after administration of the study drug. Results We did not observe any significant differences in the % predicted FEV1 and MPIS between formoterol and salbutamol at various time points from 1 min to 60 min post drug administration. There was significant improvement in FEV1 (% predicted from baseline in both the groups as early as 1 min after drug administration. Conclusions Salbutamol or formoterol delivered along with inhaled corticosteroid by metered dose inhaler with spacer in children between 5-15 years of age with mild acute exacerbation of asthma had similar bronchodilatory effects.

  2. Severe renal failure in acute bacterial pyelonephritis: Do not forget corticosteroids

    Sqalli Tarik

    2010-01-01

    Full Text Available Acute renal failure (ARF is a rare complication of acute pyelonephritis in adult immunocompetent patients. Recovery of renal function usually occurs if antibiotics are promptly initiated. However, long-term consequences of renal scarring due to acute pyelonephritis are probably underestimated, and some patients present with prolonged renal failure despite adequate antibiotic therapy. We report two cases of severe ARF complicating bacterial pyelonephritis successfully treated with corticosteroids in association with conventional antibiotics.

  6. Single dose oral dexamethasone versus multi-dose prednisolone in the treatment of acute exacerbations of asthma in children who attend the emergency department: study protocol for a randomized controlled trial

    Cronin John

    2012-08-01

    Full Text Available Abstract Background Asthma is a major cause of pediatric morbidity and mortality. In acute exacerbations of asthma, corticosteroids reduce relapses, subsequent hospital admission and the need for ß2-agonist therapy. Prednisolone is relatively short-acting with a half-life of 12 to 36 hours, thereby requiring daily dosing. Prolonged treatment course, vomiting and a bitter taste may reduce patient compliance with prednisolone. Dexamethasone is a long-acting corticosteroid with a half-life of 36 to 72 hours. It is used frequently in children with croup and bacterial meningitis, and is well absorbed orally. The purpose of this trial is to examine whether a single dose of oral dexamethasone (0.3 mg/kg is clinically non-inferior to prednisolone (1 mg/kg/day for three days in the treatment of exacerbations of asthma in children who attend the Emergency Department. Methods/design This is a randomized, non-inferiority, open-label clinical trial. After informed consent with or without assent, patients will be randomized to either oral dexamethasone 0.3 mg/kg stat or prednisolone 1 mg/kg/day for three days. The primary outcome measure is the comparison between the Pediatric Respiratory Assessment Measure (PRAM across both groups on Day 4. The PRAM score, a validated, responsive and reliable tool to determine asthma severity in children aged 2 to 16 years, will be performed by a clinician blinded to treatment allocation. Secondary outcomes include relapse, hospital admission and requirement for further steroid therapy. Data will be analyzed on an intention-to-treat and a per protocol basis. With a sample size of 232 subjects (105 in each group with an estimated 10% loss to follow-up, we will be able to reject the null hypothesis - that the population means of the experimental and control groups are equal with a probability (power of 0.9. The Type I error probability associated with this test (of the null hypothesis is 0.05. Discussion This

    2011-08-01

    ADAM33, a member of the ADAM (a disintegrin and metalloprotease) gene family, is an asthma susceptibility gene originally identified by positional cloning. In the present study, we investigated the possible association of five single-nucleotide polymorphisms (SNPs) in the ADAM33 (rs511898, rs528557, rs44707, rs597980 and rs2787094) with adult-onset asthma in an Indian population. The study included 175 patients with mild intermittent ($n = 44$), mild persistent ($n = 108$) or moderate persistent ($n = 23$) subgroups of asthma, and 253 nonasthmatic control individuals. SNPs were genotyped with the help of restriction fragment length polymorphism polymerase chain reaction (RFLP-PCR) method, and data were analysed using chi-square test and logistic regression model. Bonferroni’s correction for multiple comparisons was applied for each hypothesis. Genotypes and allele frequencies of SNPs rs511898 and rs528557 were significantly associated with adult-onset asthma ($P = 0.010-\\lt 0.001$). A significant association of the homozygous mutant genotype and mutant alleles of SNPs rs2787094, rs44707 and rs597980 with the asthma was also observed ($P = 0.020-\\lt 0.001$). A positive association between asthma and haplotypes AGCCT, GGCCT, AGACT, GCAGT, GGACT, ACCCC and AGACC were also found ($P = 0.036-\\lt 0.001$, OR $= 2.07-8.49$). Haplotypes AGCGT, GCAGC, ACAGC, ACAGT, GGAGC and GGCGT appear to protect against asthma ($P = 0.013-\\lt 0.0001$, OR $= 0.34-0.10$). Our data suggest that ADAM33 gene polymorphisms serve as genetic risk factors for asthma in Indian adult population.

    The side effects of tamoxifen are generally mild, including the effect on lipoprotein metabolism. However, there are few cases of severe tamoxifen induced hypertriglyceridemia. Hypertriglyceridemia is a marked risk factor for acute pancreatitis and approximately 2% to 5% of cases of acute pancreatitis are related to drugs. We report on tamoxifen-induced hypertriglyceridemia and acute pancreatitis in a 40 years old woman with type 2 diabetes mellitus occurred by dexamethasone. She was treated with insulin infusion and fenofibrate, and goserelin acetate was started instead of tamoxifen after discharge from the hospital. Also, probable pathogenic hypotheses about the correlation between tamoxifen and dexamethasone induced type 2 diabetes mellitus on severe acute pancreatitis are provided. Clinicians should take care of risks of severe acute pancreatitis on using tamoxifen, especially for patients with dexamethasone induced diabetes mellitus. These individuals should undergo pre-post tamoxifen lipid screening and careful history taking of drugs, including dexamethasone. PMID:25035662

    Abstract Background Severe acute respiratory syndrome (SARS), a recent epidemic human disease, is caused by a novel coronavirus (SARS-CoV). First reported in Asia, SARS quickly spread worldwide through international travelling. As of July 2003, the World Health Organization reported a total of 8,437 people afflicted with SARS with a 9.6% mortality rate. Although immunopathological damages may account for the severity of respiratory distress, little is known about how the genome-wide gene expr...

    The use of intravenous aminophylline in the treatment of children with acute asthma remains controversial. Most authors suggest that aminophylline be used with caution because of its poor efficacy with adverse reactions and instead recommend other drugs, such as {beta}{sub 2}-adrenergic agonists and glucocorticoids. However other studies have reported the benefits of aminophylline, and current Japanese guidelines for the management of asthma recommend its use. Here, we have evaluated the efficacy of aminophylline infusion in children with acute asthma exacerbations. Twenty children with acute asthma exacerbations were given an infusion of 5 mg/kg of aminophylline over 5 minutes, 30 minutes after the same volume of normal saline had been infused as a control. {sup 81m}Kr ventilation scintigraphy was done sequentially, and lung function was measured with spirometry before and after each infusion. Side effects were also evaluated with a questionnaire. Ventilation images obtained with {sup 81m}Kr scintigraphy, which initially showed widespread ventilatory defects caused by bronchoconstriction, decreased 54.9% after aminophylline infusion (p<0.0001). Ventilatory defects, caused by both central and peripheral airway disturbances and confirmed with the {sup 81m}Kr bolus inhalation procedure, also showed significant improvement (p<0.0001). These improvement were accompanied by improvements in lung function as assessed with forced expiratory volume in 1 second (p<0.01) and maximum expiratory flow rates at 25% (p<0.001) and 50% (p<0.001). No serious adverse reactions were recognized in any subjects. Our results show that aminophylline is a useful bronchodilator which decreased ventilatory imbalance and improves lung function in both central and peripheral airways. (author)

    prednisone in patients with acute asthma. METHODS: Randomized double-blind, double-dummy and placebo-controlled clinical trial. Forty-nine children aged 2 to 7 years with acute asthma were randomized in three groups after receiving nebulized salbutamol (0.15 mg/kg. Group I received placebo both as tablets and nebulization, group II was treated with a single dose of oral prednisone (1 mg/kg and inhaled placebo, and group III received a single dose of placebo tablet and nebulized budesonide (2 mg. Patients were evaluated in terms of symptom score and transcutaneous hemoglobin saturation. Nebulized salbutamol was repeated in case of increasing symptom score or lower saturation. RESULTS: Progressive clinical improvement was observed in all three groups. However, a significant increase in hemoglobin saturation was observed after 2 hours with prednisone, 4 hours with budesonide, and 24 hours with placebo. CONCLUSION: A combination of single-dose nebulized budesonide and salbutamol may be as effective as oral prednisone to improve symptom severity, but the latter increases hemoglobin saturation in exacerbation of asthma.

    1987-09-01

    A 42 year-old woman with severe acute pancreatitis had drainage of the pancreatic bed, cholecystostomy and jejunostomy on admission, but symptoms were not improved. Fourteen days after admission, clinical sepsis and septisemia were recognized. Dynamic CT scanning of the pancreas showed near total pancreatic necrosis. Symptoms were improved after necrosectomy of the pancreas and debridement of the peripancreatic necrotic tissue were performed. Our experience suggests the usefulness of dynamic CT scanning for detection of pancreatic necrosis in severe acute pancreatitis.

    Raffaele Pezzilli

    2012-01-01

    Selecting patients with severe acute pancreatitis as early as possible after the onset of symptoms is crucial for appropriate treatment [1]. The guidelines indicate that the assessment of severity should be carried out as soon as possible by a scoring system, such as Acute Physiology and Chronic Health Evaluation (APACHE) II which is a grade A recommendation [2, 3]. The comment added by the authors of the Italian guidelines is that an APACHE II score greater than 8 is important for determinin...

    2015-01-01

    Background The term severe acute respiratory infection (SARI) encompasses a heterogeneous group of respiratory illnesses. Grading the severity of SARI is currently reliant on indirect disease severity measures such as respiratory and heart rate, and the need for oxygen or intensive care. With the lungs being the primary organ system involved in SARI, chest radiographs (CXRs) are potentially useful for describing disease severity. Our objective was to develop and validate a SARI CXR severity s...

  11. The Imaging Assessment of the Severity of Acute Pancreatitis May Change in the Near Future

    Raffaele Pezzilli

    2005-09-01

    Full Text Available The diagnosis and the assessment of the severity of acute pancreatitis has been completely revolutionized by the routine use of dynamic contrast-enhanced computed tomography (CT in clinical practice. Furthermore, objective CT assessment of the disease has made the various diagnostic and therapeutic studies on acute pancreatitis comparable for the first time [1, 2, 3, 4]. CT has two major roles for patients with suspected acute pancreatitis: to evaluate the severity of the inflammatory process and to detect the complications of the disease , such as the identification and quantification of parenchymal necrosis early. The CT severity index proposed by Balthazar et al. [5] is at present largely applied in all pancreatological centers in the world in order to assess and to stratify the severity of acute pancreatitis. Because the CT findings of necrosis may be equivocal during the first 24-48 hours, it has been suggested that the initial CT scan obtained in patients with clinically severe acute pancreatitis should be done after this period [6, 7]. CT is also largely used to obtain pancreatic specimens for microbiological examination in order to detect the presence of bacterial contamination in pancreatic necrosis [8]; using this imaging technique, we are also able to treat some of the complications of acute pancreatitis such as infected fluid collections and pseudocysts [9, 10].

  12. Thunderstorm asthma: an overview of the evidence base and implications for public health advice.

    Dabrera, G; Murray, V; Emberlin, J; Ayres, J G; Collier, C; Clewlow, Y; Sachon, P

    2013-03-01

    Thunderstorm asthma is a term used to describe an observed increase in acute bronchospasm cases following the occurrence of thunderstorms in the local vicinity. The roles of accompanying meteorological features and aeroallergens, such as pollen grains and fungal spores, have been studied in an effort to explain why thunderstorm asthma does not accompany all thunderstorms. Despite published evidence being limited and highly variable in quality due to thunderstorm asthma being a rare event, this article reviews this evidence in relation to the role of aeroallergens, meteorological features and the impact of thunderstorm asthma on health services. This review has found that several thunderstorm asthma events have had significant impacts on individuals' health and health services with a range of different aeroallergens identified. This review also makes recommendations for future public health advice relating to thunderstorm asthma on the basis of this identified evidence. PMID:23275386

    Objective: To study MRI findings of abdominal wall edema (AWE) in acute pancreatitis as well as correlations between AWE and the severity of acute pancreatitis according to the MR severity index (MRSI) and the Acute Physiology And Chronic Healthy Evaluation III (APACHE III) scoring system. Materials and methods: A total of 160 patients with AP admitted to our institution between December 2009 and March 2011 were included in this study. MRI was performed within 48 h after admission. MRI findings of acute pancreatitis were noted, including AWE on the MRI. The abdominal wall area was divided into quarters, and each area involved was recorded as 1 point to score the severity of AWE. The severity of acute pancreatitis was studied using both the MRSI and the APACHE III scoring system. Spearman correlation of AWE with the MRSI and the APACHE III scoring system was analyzed. Results: In 160 patients with acute pancreatitis, 53.8% had AWE on MRI. The average AWE score was 1.2 {+-} 1.4 points. The prevalence of AWE was 30.5%, 64.5% and 100% in mild, moderate and severe AP, respectively, according to MRSI. AWE on MRI was correlated with MRSI scores (r = 0.441, p = 0.000). According to APACHE III scores, the averages were 2.0 {+-} 1.1 and 2.6 {+-} 1.1 points in mild AP and severe AP, respectively (P = 0.016). AWE was slightly correlated with the APACHE III scores (r = 0.222, p = 0.005). Conclusion: AWE on MRI in acute pancreatitis is common, which may be a supplementary indicator in determining the severity of AP.

    2009-01-01

    Full Text Available Background/Aims. At present, there is no simple test for predicting severity in acute pancreatitis. We investigated the use of an assay of soluble E-cadherin (sE-cadherin. Methods. Concentrations of sE-cadherin, from 19 patients with mild acute pancreatitis, 7 patients with severe acute pancreatitis, 11 patients with other acute gastrointestinal pathologies, and 12 healthy subjects were measured using a commercially available sandwich ELISA kit based on two monoclonal antibodies specific to the extracellular fragment of human E-cadherin. Measurements were made at 12 hours or less from onset of pain and also at 24 and 48 hours after onset of pain. Results. Mean (standard deviation concentration of sE-cadherin in patients with severe acute pancreatitis at <12 hours was 17780 ng/mL (7853, significantly higher than that of healthy volunteers 5180 ng/mL (1350, =.0039, patients with other gastrointestinal pathologies 7358 ng/mL (6655, =.0073, and also significantly higher than that of patients with mild pancreatitis, 7332 ng/mL (2843, =.0019. Discussion. Serum sE-cadherin could be an early (within 12 hours objective marker of severity in acute pancreatitis. This molecule warrants further investigation in the form of a large multicentre trial.

    Yoshioka, Wakako; Mori, Takayasu; Nagahama, Kiyotaka; Tamura, Teiichi

    2013-01-01

    We report a 49-year-old man with alcoholic severe acute pancreatitis (SAP) complicated by drug-induced acute tubulointerstitial nephritis (DI-AIN). Oliguria persisted and became anuric again on day 17 despite improvement of pancreatitis. He presented rash, fever and eosinophilia from day 20. Renal biopsy was performed for dialysis-dependent acute kidney injury (AKI), DI-AIN was revealed, and prompt use of corticosteroids fully restored his renal function. This diagnosis might be missed because it is difficult to perform renal biopsy in such a clinical situation. If the patient's general condition allows, renal biopsy should be performed and reversible AKI must be distinguished from many cases of irreversible AKI complicated by SAP. This is the first report of biopsy-proven DI-AIN associated with SAP, suggesting the importance of biopsy for distinguishing DI-AIN in persisting AKI of SAP. PMID:23645698

    Beard, T; Boudjemaa, B; Carrié, D; Chakra, G; Ferrières, J; Delay, M; Bernadet, P

    1993-05-01

    This study reports two cases of acute severe Coxsackie virus B4 myocarditis in which the immediate clinical signs suggested the acute phase of myocardial infarction, apparently antero-lateral in the first case in a context of cardiogenic shock and infero-lateral in the second case, in the context of acute pulmonary edema. Both cases were characterized by the severity of the initial signs. Numerous other cases of acute Coxsackie virus B myocarditis, simulating myocardial infarction, have been reported in the literature and these contexts deserve to be recognized earlier as they call for specific treatment. The immediate outcome was favorable in both cases but required massive cardiological intensive care in the first patient. Long term follow-up was excellent. PMID:8396381

    Rodgers, Bradley K; Kumar, Avinash B

    2016-01-01

    Toxic epidermal necrolysis syndrome (TEN) is a rare severe cutaneous adverse drug reaction that involves skin and mucous membranes. We describe a case of TEN presenting with stage III acute kidney injury, rhabdomyolysis, and acute respiratory failure likely triggered by allopurinol for recently diagnosed gout. Prompt diagnosis, multidisciplinary management, including aggressive resuscitation, cardiorespiratory support, intravenous immunoglobulin therapy, and daily wound care resulted in a positive outcome despite a predicted mortality greater than 60%. Although allopurinol is a known triggering agent, TEN presenting with rhabdomyolysis and acute kidney injury is rare. PMID:24832386

While initial bone marrow biopsy lacked any cytogenetic abnormalities in 20 analyzed metaphases, repeat bone marrow biopsy eight days later demonstrated this translocation. Initial cytogenetic analysis of 20 metaphases was therefore insufficient to make the diagnosis of hypocellular acute myeloid leukemia. We discuss that further complementary molecular tests, such as CGH, would likely provide a more robu...

  13. MRI versus acute physiology and chronic healthy evaluation Ⅲ score for the assessment of the severity of acute pancreatitis

    Objective: To study the severity of acute pancreatitis (AP) by using MRI and the acute physiology and chronic healthy evaluation Ⅲ (APACHE Ⅲ) score, and the correlation between corresponding MRI findings and APACHE Ⅲ scores. Methods: One hundred patients with AP undergoing abdominal MRI were recruited in the study. The MRI features of acute pancreatitis were recorded. The severity of AP on MRI was graded by MR severity index (MRSI) as mild (0 to 2 points), moderate (3 to 6 points) and severe (7 to 10 points). APACHE Ⅲ score was denoted for AP was as mild (< 35 points) and severe (≥ 35 points). The local and systematic complications,mortality, need to intense care unit (ICU), and hospitalization time were recorded and compared with MRSI and APACHE Ⅲ score. Nonparametric Spearman correlation was calculated for testing the correlation between the MRSI, the APACHE Ⅲ and hospitalization time. The correlation of clinical results with MRSI and APACHE Ⅲ was calculated by χ2 test. Results: In the 100 patients with AP,there were respectively 80 and 20 patients with edematous and necrotic pancreatitis on MRI. According to MRSI, 34, 59 and 7 patients had mild, moderate, and severe acute pancreatitis,respectively. The APACHE Ⅲ score was (24.9 ± 12.2) points. Seventy-seven patients had less than 35 points and 23 patients had more than 35 point of APACHE Ⅲ score. There were significant differences in the local complication, systematic complication, need to ICU among the three groups in MRSI score, respectively (χ2=9.161, 19.118, 54.767; P<0.01). There was difference in the systematic complication between mild and severe AP in APACHE Ⅲ score (χ2=13.120, P=0.000), but there were no differences (χ2=0.245, χ2=2.568; P>0.05) in the local complication,need to ICU between mild and severe AP in APACHE Ⅲ score. There was weak correlation (r=0.235, P=0.019) between MRSI score and hospitalization time,and no difference (r=0.168, 0.105; P>0.05) between APACHE

    Loretta YC Yam; Alfred YF Chan; Thomas MT Cheung; Eva LH Tsui; Jane CK Chan; Vivian CW Wong

    2005-01-01

    Background Severe acute respiratory syndrome is frequently complicated by respiratory failure requiring ventilatory support. We aimed to compare the efficacy of non-invasive ventilation against invasive mechanical ventilation treating respiratory failure in this disease. Methods Retrospective analysis was conducted on all respiratory failure patients identified from the Hong Kong Hospital Authority Severe Acute Respiratory Syndrome Database. Intubation rate, mortality and secondary outcome of a hospital utilizing non-invasive ventilation under standard infection control conditions (NIV Hospital) were compared against 13 hospitals using solely invasive ventilation (IMV Hospitals). Multiple logistic regression analyses with adjustments for confounding variables were performed to test for association between outcomes and hospital groups. Results Both hospital groups had comparable demographics and clinical profiles, but NIV Hospital (42 patients) had higher lactate dehydrogenase ratio and worse radiographic score on admission and ribavirin-corticosteroid commencement. Compared to IMV Hospitals (451 patients), NIV Hospital had lower adjusted odds ratios for intubation (0.36, 95% CI 0.164-0.791, P=0.011) and death (0.235, 95% CI 0.077-0.716, P=0.011), and improved earlier after pulsed steroid rescue. There were no instances of transmission of severe acute respiratory syndrome among health care workers due to the use of non-invasive ventilation.Conclusion Compared to invasive mechanical ventilation, non-invasive ventilation as initial ventilatory support for acute respiratory failure in the presence of severe acute respiratory syndrome appeared to be associated with reduced intubation need and mortality.

  16. CT findings and CT score in acute pancreatitis compared with severity

    CT findings in 28 patients with acute pancreatitis were compared with severity of the disease. The pancreatic image, which demonstrates the pancreatic lesion, was studied with respect to 9 items, and fluid collection showing the peripancreatic status with respect to 13 items. 1) According to Forell's classification, the lesion was minor in 8 patients, moderate in 11, and severe in 9. 2) The detection rates of abnormal pancreatic images and fluid collection increased with the advance in the severity of the disease. 3) The mean CT score by severity was 0.88 ± 0.64 for minor pancreatitis, 7.18 ± 4.51 for moderate pancreatitis, and 13.44 ± 4.22 for severe pancreatitis. Significant differences were observed among the groups, suggesting the usefulness of the CT score in evaluating the severity of acute pancreatitis. (author)

    2015-10-01

    Macrophages are crucially involved in the pathophysiology of acute pancreatitis. Soluble CD163 (sCD163) is specifically released from macrophages and systemic levels are increased in inflammatory diseases. Here, sCD163 was measured in serum of 50 patients with acute pancreatitis to find out possible associations with disease activity. Admission levels of systemic sCD163 were nearly three-fold higher in patients with acute pancreatitis compared to controls. In patients sCD163 did not correlate with C-reactive protein and leukocyte count as established markers of inflammation. Levels were not associated with disease severity assessed by the Schroeder score, Balthazar score, Acute Physiology, Age, and Chronic Health Evaluation (Apache) II score and peripancreatic necrosis score. Soluble CD163 was not related to complications of acute pancreatitis. These data show that serum sCD163 is increased in acute pancreatitis indicating activation of macrophages but is not associated with disease severity and outcome. PMID:26209500

    Ghone, Rahul A.; Suryakar, Adinath N.; Kulhalli, P. M.; Bhagat, Sonali S.; Padalkar, Ramchandra K.; Karnik, Aarti C.; Hundekar, Prakash S.; Sangle, D. A.

    2013-01-01

    Background: Malnutrition represents one of the most severe health problems in India. Free radicals play an important role in immunological response, which induces the oxidative surplus in severe acute malnutrition. Severe dietary deficiency of nutrients leads to increased oxidative stress in cellular compartments. Aim: The goal of this study was to inspect impact of oxidative stress in the form of serum malondialdehyde as product of lipid peroxidation, vitamin E, zinc and erythrocyte superoxide dismutase in patients with severe acute malnutrition. Material and Methods: Sixty severe acute malnutrition patients were studied before and after supplementation of antioxidants for one month, and their status were compared with those of 60 age and sex matched healthy controls. The level of serum MDA was analyzed by the Kei Satoh method, serum vitamin E concentration was measured by Baker and Frank Method, serum zinc was measured by using Atomic Absorption Spectrophotometer (AAS) and erythrocyte superoxide dismutase was measured by Kajari Das Method. Results: Significantly increased levels of serum malondialdehyde (p0.05) increase in vitamin E levels as compared to those before supplementation results. Conclusion: Harsh deficiency of various nutrients in severe acute malnutrition leads to generation of heavy oxidative stress. These effects may be minimized with supplementation of antioxidants.

  20. The cost of asthma: can it be reduced?

    Mellis, C M; Peat, J K; Woolcock, A J

    1993-03-01

    Asthma is a major public health problem in developed countries, where it consumes a large and increasing share of scarce health resources. Ideally, medical management should be both optimal in terms of improving the patient's quality of life, and cost-effective for society. At present, there is very little information relating to costs and economic efficiency of current asthma management. Although the true total cost of asthma is unknown, current estimates suggest it is high. The main value of recent total cost estimates is that they identify the most expensive areas of asthma costs, and ideally, formal cost-effectiveness analyses should be concentrated on these areas. Asthma is still under- or inappropriately diagnosed, and undertreated. Several national and international consensus plans for the optimal management of asthma in children and adults have been published. If these inadequacies in asthma management were corrected, using current treatment recommendations, the overall cost of asthma from both the community and patient perspective should fall. The situation requires increased use of preventative medications {sodium cromoglycate (cromolyn sodium) or inhaled corticosteroids}, more widespread use of written crisis plans, more proactive medical consultations (rather than reactive or urgent consultations), further expansion of asthma education programmes, and further education of medical practitioners about the optimum management of both long term asthma and the acute exacerbation of asthma in the patient's home, the doctor's office, the hospital emergency room and the hospital inpatient setting. The increased costs associated with these measures would be more than offset by reduced expenditure on bronchodilator drugs, less widespread use of nebulisers at home and in hospitals, reduced antibiotic usage, reduced need for expensive emergency medical care and particularly reduced utilisation of hospital resources. To ensure that resources are being directed into

  1. Psychological aspects of asthma.

    Asthma can be affected by stress, anxiety, sadness, and suggestion, as well as by environmental irritants or allergens, exercise, and infection. It also is associated with an elevated prevalence of anxiety and depressive disorders. Asthma and these psychological states and traits may mutually potentiate each other through direct psychophysiological mediation, nonadherence to medical regimen, exposure to asthma triggers, and inaccuracy of asthma symptom perception. Defensiveness is associated with inaccurate perception of airway resistance and stress-related bronchoconstriction. Asthma education programs that teach about the nature of the disease, medications, and trigger avoidance tend to reduce asthma morbidity. Other promising psychological interventions as adjuncts to medical treatment include training in symptom perception, stress management, hypnosis, yoga, and several biofeedback procedures.

  2. Monitoring asthma in childhood

    Karin C. Lødrup Carlsen

    2015-06-01

    Full Text Available The goal of asthma treatment is to obtain clinical control and reduce future risks to the patient. However, to date there is limited evidence on how to monitor patients with asthma. Childhood asthma introduces specific challenges in terms of deciding what, when, how often, by whom and in whom different assessments of asthma should be performed. The age of the child, the fluctuating course of asthma severity, variability in clinical presentation, exacerbations, comorbidities, socioeconomic and psychosocial factors, and environmental exposures may all influence disease activity and, hence, monitoring strategies. These factors will be addressed in herein. We identified large knowledge gaps in the effects of different monitoring strategies in children with asthma. Studies into monitoring strategies are urgently needed, preferably in collaborative paediatric studies across countries and healthcare systems.

    2002-01-01

    Cigarette smoking is a well-known health hazard, probably not least for patients suffering from asthma. This review gives a short overview of the effects of passive and active smoking on the inception and outcome with of longitudinal changes in the lung function and mortality of patients with...... asthma. Substantial evidence suggests that smoking affects asthma adversely. Exposure to environmental tobacco smoke, especially maternal smoking in children, may be a significant risk factor for asthma. Such exposure in patients with established asthma is not only associated with more severe symptoms......, but also with a poorer quality of life, reduced lung function, and increased utilisation of health care including hospital admissions. Active smoking does not appear to be a significant risk factor for asthma, but is associated with a worse outcome with regard to both longitudinal changes in lung...

    2010-07-01

    Full Text Available Context Pancreatitis is a very rare adverse effect of tamoxifen with only six cases of tamoxifen-associated pancreatitis reported in the English literature until now. In these cases, rechallenge with tamoxifen was not carried out. Case report We report a case of recurrent severe acute pancreatitis in a 44-year-old female induced by tamoxifen therapy and review the literature with regards to tamoxifen-associated pancreatitis. Conclusion Clinicians should be aware of the risks of developing severe acute pancreatitis when using tamoxifen therapy. If tamoxifen is suspected as the probable causative agent, rechallenge with this drug should be prohibited.

    Carlsen, Kai-Håkon

    2016-01-01

    High prevalence of asthma has been reported repeatedly among elite athletes, especially among endurance athletes. So many athletes used asthma drugs that the objective demonstration of bronchial hyperresponsiveness was required to obtain approval for their use in international sports until 2012 when the most used inhaled asthma drugs was allowed for free use, but with a maximum dose for inhaled β2-agonists. Several factors contribute to the development of asthma among the Olympians causing airways inflammation and bronchial hyper-responsiveness. PMID:26631837

  9. Valproic Acid-Induced Severe Acute Pancreatitis with Pseudocyst Formation: Report of a Case.

    Ray, Sukanta; Khamrui, Sujan; Kataria, Mohnish; Biswas, Jayanta; Saha, Suman

    2015-08-01

    Valproic acid is the most widely used anti-epilep-tic drug in children, and it is probably the most frequent cause of drug-induced acute pancreatitis. Outcomes for patients with valproic acid-associated pancreatitis vary from full recovery after discontinuation of the drug to severe acute pancreatitis and death. Here, we present a case of valproic acid-induced severe acute pancreatitis with pseudocyst formation in a 10-year-old girl with cerebral palsy and generalized tonic-clonic seizure. There was no resolution of the pseudocyst after discontinuation of valproic acid. The patient became symptomatic with a progressive increase in the size of the pseudocyst. She was successfully treated with cystogastrostomy and was well at 12-month follow-up. PMID:26366333

  10. Impairment of Venous Drainage on Extracorporeal Membrane Oxygenation Secondary to Air Trapping in Acute Asphyxial Asthma.

    Niimi, Kevin S; Lewis, Leslie S; Fanning, Jeffrey J

    2015-06-01

    The inability to adequately support a patient on extracorporeal membrane oxygenation (ECMO) due to impaired drainage is not an uncommon occurrence during support. Typically, the causes include hypovolemia, kinks in the circuit, cannula malposition, or inadequate cannula size. In this report we present an uncommon etiology of this problem. A 3-year-old female presented to our hospital in status asthmaticus and pulseless electrical activity (PEA). This was a result of dynamic hyperinflation of the lungs causing physical obstruction of venous return to the heart. Upon initiating venoarterial (VA) ECMO, we experienced inadequate drainage that did not improve despite multiple interventions. This resolved with the addition of an inhaled anesthetic gas to treat this patient's severe bronchospasm. This case illustrates the importance of considering a patient's physiology or disease state and how that may affect the mechanics of ECMO support. PMID:26405359

    Objective To describe the impact of omalizumab on asthma management in patients treated as part of normal clinical practice in the UK National Health Service (NHS). Design A non-interventional, mixed methodology study, combining retrospective and prospective data collection for 12 months pre-omalizumab and post-omalizumab initiation, respectively. Setting Data were collected in 22 UK NHS centres, including specialist centres and district general hospitals in the UK. Participants 258 adult patients (aged ≥16 years; 65% women) with severe persistent allergic asthma treated with omalizumab were recruited, of whom 218 (84.5%) completed the study. Primary and secondary outcome measures The primary outcome measure was change in mean daily dose of oral corticosteroids (OCS) between the 12-month pre-omalizumab and post-omalizumab initiation periods. A priori secondary outcome measures included response to treatment, changes in OCS dosing, asthma exacerbations, lung function, employment/education, patient-reported outcomes and hospital resource utilisation. Results The response rate to omalizumab at 16 weeks was 82.4%. Comparing pre-omalizumab and post-omalizumab periods, the mean (95% CIs) daily dose of OCS decreased by 1.61 (−2.41 to −0.80) mg/patient/day (p<0.001) and hospital exacerbations decreased by 0.97 (−1.19 to −0.75) exacerbations/patient (p<0.001). Compared with baseline, lung function, assessed by percentage of forced expiratory volume in 1 s, improved by 4.5 (2.7 to 6.3)% at 16 weeks (p<0.001; maintained at 12 months) and patient quality of life (Asthma Quality of Life Questionnaire) improved by 1.38 (1.18 to 1.58) points at 16 weeks (p<0.001, maintained at 12 months). 21/162 patients with complete employment data gained employment and 6 patients lost employment in the 12-month post-omalizumab period. The mean number of A&E visits, inpatient hospitalisations, outpatient visits (excluding for omalizumab) and number of bed days

  12. Effects of nonlinear error correction of measurements obtained by peak flowmeter using the Wright scale to assess asthma attack severity in children

    Stamatović Dragana

    2007-01-01

    Full Text Available Introduction: Monitoring of peak expiratory flow (PEF is recommended in numerous guidelines for management of asthma. Improvements in calibration methods have demonstrated the inaccuracy of original Wright scale of peak flowmeter. A new standard, EN 13826 that was applied to peak flowmeter was adopted on 1st September 2004 by some European countries. Correction of PEF readings obtained with old type devices for measurement is possible by Dr M. Miller’s original predictive equation. Objective. Assessment of PEF correction effect on the interpretation of measurement results and management decisions. Method. In children with intermittent (35 or stable persistent asthma (75 aged 6-16 years, there were performed 8393 measurements of PEF by Vitalograph normal-range peak flowmeter with traditional Wright scale. Readings were expressed as percentage of individual best values (PB before and after correction. The effect of correction was analyzed based on The British Thoracic Society guidelines for asthma attack treatment. Results. In general, correction reduced the values of PEF (p<0.01. The highest mean percentage error (20.70% in the measured values was found in the subgroup in which PB ranged between 250 and 350 l/min. Nevertheless, the interpretation of PEF after the correction in this subgroup changed in only 2.41% of measurements. The lowest mean percentage error (15.72%, and, at the same time, the highest effect of correction on measurement results interpretation (in 22.65% readings were in children with PB above 450 l/min. In 73 (66.37% subjects, the correction changed the clinical interpretation of some values of PEF after correction. In 13 (11.8% patients, some corrected values indicated the absence or a milder degree of airflow obstruction. In 27 (24.54% children, more than 10%, and in 12 (10.93%, more than 20% of the corrected readings indicated a severe degree of asthma exacerbation that needed more aggressive treatment. Conclusion

  13. Comparison of BISAP Score with Ranson Score in Determining the Severity of Acute Pancreatitis

    Objective:To determine the accuracy of BISAPscore in finding out the frequency of severity and mortality in patients with acute pancreatitis by comparing it with Ranson score. Study Design: Crosse-sectional study. Place and Duration of Study: Department of Surgery, Pakistan Institute of Medical Sciences, Islamabad, from April to December 2010. Methodology: A total of 80 patients who presented in emergency with acute pancreatitis were included by consecutive non probability sampling technique. Cases of acute pancreatitis were classified as mild or severe based on the organ failure criteria and/or local complications according to the Atlanta Symposium. All patients were scored according to both Ranson score and BISAP score. Results: Out of 80 patients, 35 (44 percentage) were males and 45 (56 percentage) were females. The mean age was 46.89 ± 15.75 years. Twenty five patients (31.25 percentage) were classified as severe acute pancreatitis and 3 patients (3.75 percentage) had evidence of pancreatic necrosis on CT scan. The duration of hospital stay was 1 - 54 days with a mean of 13.12 ± 12.83 days and mortality rate was 5 percentage. The number of patients with a BISAP score of =3 was 15 and Ranson score =3 was 25. The observed incidence of severe disease stratified by the BISAP score has (p greater than 0.001) and by Ranson score has (p greater than 0.001). In regards to mortality, patients having BISAP score =3 has p=0.003, while patients having Ranson score =3 has p=0.002, both are statistically significant. Conclusion:The newly proposed BISAPscore is a simple and accurate tool for severity stratification and is equally effective in finding out frequency of severity and in turns mortality in patients with acute pancreatitis as Ranson score.

  1. Magnetic resonance imaging versus Acute Physiology And Chronic Healthy Evaluation II score in predicting the severity of acute pancreatitis

    Objective: To study the correlation between established magnetic resonance (MR) imaging criteria of disease severity in acute pancreatitis and the Acute Physiology And Chronic Healthy Evaluation II (APACHE II) score, and to assess the utility of each prognostic indicators in acute pancreatitis. Materials and methods: In this study there were 94 patients with acute pancreatitis (AP), all had abdominal MR imaging. MR findings were categorized into edematous and necrotizing AP and graded according to the MR severity index (MRSI). The APACHE II score was calculated within 24 h of admission, and local complications, death, duration of hospitalization and ICU were recorded. Statistical analysis was performed to determine their correlation. Results: In patients with pancreatitis, no significant correlation can be found between the APACHE II score and the MRSI score (P = 0.196). The MRSI score correlated well with morbidity (P = 0.006) but not with mortality (P = 0.137). The APACHE II score correlated well with mortality (P = 0.002) but not with the morbidity (P = 0.112). The MRSI score was superior to the APACHE II score as a predictor of the length of hospitalization (r = 0.52 vs. r = 0.35). A high MRSI and APACHE II score correlated with the need for being in the intensive care unit (ICU) (P = 0.000 and P = 0.000, respectively). Conclusion: In patients with pancreatitis, MRSI is superior to APACHE II in assessing local complications from pancreatitis but has a limited role in determining systemic complications in which the APACHE II score excels.

  4. Acute liver injury with severe coagulopathy in marasmus caused by a somatic delusional disorder.

    Stein, Lance L; Jesudian, Arun B

    2011-01-01

    Marasmus is a severe form of protein-calorie malnutrition characterized by the depletion of fat stores, muscle wasting, and the lack of edema. In developed countries, marasmus is often the result of anorexia nervosa. Abnormal transaminases with liver synthetic dysfunction have rarely been reported with anorexia nervosa. To our knowledge, we report the first detailed case of acute liver injury with severe coagulopathy (INR > 1.5) in a patient with marasmus due to self-induced calorie restriction caused by a somatic delusional disorder. This case highlights the severity of liver injury that may occur with significant weight loss from self-induced calorie restriction and the rapid normalization of this injury with treatment. It is important for clinicians to be aware of patterns of acute liver injury in patients with severe protein-calorie malnutrition, regardless of the underlying cause. PMID:25954537

    2013-01-01

    Asthma is a disease with distinct phenotypes that have implications for both prognosis and therapy. Epidemiologic studies have demonstrated an association between asthma and obesity. Further studies have shown that obese asthmatics have poor asthma control and more severe asthma. This obese-asthma group may represent a unique phenotype. The mechanisms behind poor asthma control in obese subjects remain unclear, but recent research has focused on adipokines and their effects on the airways as ...

    Pharmacologic modulation of hypermetabolism clearly benefits children with major burns, however, its role in adult burns remains to be defined. Oxandrolone appears to be a promising anabolic agent although few outcome data are as yet available. We examined whether early oxandrolone treatment in severely burned adults was associated with improved outcomes during acute hospitalization. We evaluated for potential associations between oxandrolone treatment and outcomes in a large cohort of severe...

  7. X-CT evaluation of the severity of acute pancreatitis; A new 10-point criteria

    Kim, Jung-Hyo (Osaka City Univ. (Japan). Faculty of Medicine)

    1990-09-01

    In some patients with acute pancreatitis, some experience life-threatening complications. Although there are reports of the assessment of the severity of the disease, mainly based on clinical signs and laboratory findings, pertinent criteria remain elusive. As little information is available concerning the degree or extent of pancreatic lesions; it is difficult to predict the severity and outcome. I examined 74 patients with acute pancreatitis, using computed tomography (CT). The severity was evaluated by means of a CT-score consisting of ten points on the CT findings, in the early stage of the acute pancreatitis. The following results were obtained. (1) Infiltration into the retroperitoneal space such as anterior pararenal space was observed by CT earlier and more frequently than were changes within the pancreas parenchyma. (2) Heterogeneous density of the pancreas and involvement of the posterior pararenal space were more significant and frequently in the severe group than in the moderate or mild group. (3) CT observations made 48 hours after the onset were the most adequate for evaluating the severity in case of acute pancreatitis. (4) After evaluating the severity by the CT-score, the 74 patients were grouped into 3: mild in 46, moderate in 22 and severe in 6 patients. The CT-score revealed a significantly greater specifity and accuracy than did the clinical score, Forell's, Ranson's, or the criteria submitted by a committee for the study of this disease appointed by the Japanese Ministry of Health and Welfare. I propose that an evaluation of the severity by CT-score obtained about 48 hours after the onset of symptoms is useful for predicting the prognosis and for designing proper treatment. (author).

    2014-10-01

    Full Text Available Background: Little research has focused on the economic hardship among the insured with severe illnesses and high treatment costs, in particular, the consequence of poorer insurance coverage for high-cost illnesses. Therefore, we presented the case for identifying the experiences of insured patients with severe chronic and acute illnesses. This study identified a qualitative understanding of the economic impact of severe chronic and acute illnesses and household strategies to deal with high treatment costs. Design: Interviews were conducted with 19 insured households of three different health insurance programs with a family member that had been hospitalized for severe chronic or acute illnesses in either Banyumas or Margono Sukarjo hospitals in Banyumas, Central Java, Indonesia. A thematic analysis was applied to guide the interpretation of the data. Results: Insured households with a family member that had been hospitalized for severe chronic and acute illnesses were greatly affected by the high treatment costs. Four major issues emerged from this qualitative study: insured patients are still burdened with high out-of-pocket payments, households adopt various strategies to cope with the high cost of treatments, households experience financial hardships, and positive and negative perceptions of the insured regarding their health insurance coverage for acute and chronic illnesses. Conclusions: Askes and Jamsostek patients faced financial burdens from high cost sharing for hospital amenities, non-covered drugs, and treatments and other indirect costs. Meanwhile, Jamkesmas beneficiaries faced no financial burden for related medical services but were rather burdened with indirect costs for the carers. Households relied on internal resources to cover hospital bills as the first strategy, which included the mobilization of savings, sale of assets, and borrowing of money. External support was tapped secondarily and included financial support from

  12. Understanding mild persistent asthma in children

    Bisgaard, Hans; Szefler, Stanley J

    2005-01-01

    Limitations in asthma prevalence studies and difficulties in diagnosing pediatric asthma lead to uncertainty over the full extent of mild persistent asthma in children and adolescents. Although recent surveys have reported that the majority of pediatric patients with asthma in the United States and...... Europe have symptoms consistent with mild disease, these surveys have limitations in design. Thus, the true prevalence of mild asthma remains unknown. It is unclear whether children with mild persistent asthma progress to more severe asthma, but the risk of severe asthma exacerbations seems to be...... unrelated to the symptom severity. Clinical studies restricted to pediatric patients with mild asthma are limited, but available data do suggest substantial morbidity of mild persistent asthma in this population and support inhaled corticosteroid intervention. There is a need for further investigation into...

  14. Antibiotic Prophylaxis in Severe Acute Pancreatitis: Do We Need More Meta-Analytic Studies?

    Raffaele Pezzilli

    2009-03-01

    Full Text Available Several guidelines on acute pancreatitis suggest that carbapenems should be used prophylactically and should be continued for 14 days, and that the development of infected necrosis should be assessed using fine-needle aspiration and the sample should be cultured for germ isolation and characterization [1]. In routine clinical practice, antibiotics are used to cure both extrapancreatic infections which appear during the course of acute pancreatitis and infected pancreatic necrosis and also as a prophylaxis in those patients who have pancreatic necrosis in order to prevent possible infection from the necrosis. In the treatment of extrapancreatic infections, the most used antibiotics were cephalosporins whereas carbapenems, glycopeptides and antifungal antibiotics were the most used antibiotics in the treatment of proven infected pancreatic necrosis [2]. Moreover, there are very few topics in pancreatology which cause as much debate as that regarding the utility of antibiotic prophylaxis in severe acute pancreatitis. There are very few human randomized studies and there are more meta-analyses published than studies published. Of course, the cost of a meta-analysis is much less than carrying out a study on the efficacy of antibiotics in severe acute pancreatitis.

    Thirteen patients with acute pancreatitis underwent dynamic CT scanning. According to the Ranson's criteria, 6 and 7 patients were classified as mild and severe, respectively. The maximum Hounsfield unit (HU) of the pancreas was 40 or more in the group of mild patients and 30 or less in the group of severe patients. According to the HU of the pancreas, the HU of less than 30 was defined as severe pancreatitis, the HU between 30 and 40 as medium, and the HU of more than 40 as mild. A predictive value and sensitivity of this HU criteria were 50% and 100%, respectively, for evaluating death from acute pancreatitis; and both were 100% for evaluating pancreatitis complicated by retroperitoneal infection. Thus, dynamic CT scanning is of value in the evaluation of prognosis of pancreatitis. (N.K.).

    Although there are high survival rates for children with acute lymphoblastic leukaemia, their outcome is often counterbalanced by the burden of toxic effects. This is because reported frequencies vary widely across studies, partly because of diverse definitions of toxic effects. Using the Delphi method, 15 international childhood acute lymphoblastic leukaemia study groups assessed acute lymphoblastic leukaemia protocols to address toxic effects that were to be considered by the Ponte di Legno working group. 14 acute toxic effects (hypersensitivity to asparaginase, hyperlipidaemia, osteonecrosis, asparaginase-associated pancreatitis, arterial hypertension, posterior reversible encephalopathy syndrome, seizures, depressed level of consciousness, methotrexate-related stroke-like syndrome, peripheral neuropathy, high-dose methotrexate-related nephrotoxicity, sinusoidal obstructive syndrome, thromboembolism, and Pneumocystis jirovecii pneumonia) that are serious but too rare to be addressed comprehensively within any single group, or are deemed to need consensus definitions for reliable incidence comparisons, were selected for assessment. Our results showed that none of the protocols addressed all 14 toxic effects, that no two protocols shared identical definitions of all toxic effects, and that no toxic effect definition was shared by all protocols. Using the Delphi method over three face-to-face plenary meetings, consensus definitions were obtained for all 14 toxic effects. In the overall assessment of outcome of acute lymphoblastic leukaemia treatment, these expert opinion-based definitions will allow reliable comparisons of frequencies and severities of acute toxic effects across treatment protocols, and facilitate international research on cause, guidelines for treatment adaptation, preventive strategies, and development of consensus algorithms for reporting on acute lymphoblastic leukaemia treatment.

    BACKGROUND: The Atlanta criteria for acute pancreatitis (AP) has been revised recently. This study was to evaluate its practical value in classiifcation of AP, the severity assessment and management. METHODS: The clinical features, severity classiifcation, out-come and risk factors for mortality of 3212 AP patients who had been admitted in Ruijin Hospital from 2004 to 2011 were analyzed based on the revised Atlanta criteria (RAC) and the original Atlanta criteria (OAC). RESULTS: Compared to the OAC group, the incidence of se-vere acute pancreatitis (SAP) was decreased by approximately one half (13.9% vs 28.2%) in the RAC group. The RAC present-ed a lower sensitivity but higher speciifcity, and its predictive value for severity and poor outcome was higher than those of the OAC. The proportion of SAP diagnosis and ICU admission in the early phase in the RAC group was signiifcantly lower than that in the OAC group (P CONCLUSIONS: The RAC showed a higher predictive value for severity and poorer outcome than the OAC. However, the RAC resulted in fewer ICU admissions in the early phase due to its lower sensitivity for diagnosis of SAP. Among SAP cases, older age, high CTSI, renal and cardiovascular failure, com-plications of acute necrotic collection and walled-off necrosis were independent risk factors for mortality.

    2012-10-01

    Full Text Available Abstract Background Dengue fever is the most important arthropod born viral disease of public health significance. Although most patients suffer only from flu-like symptoms, a small group of patient experiences more severe forms of the disease. To contribute to a better understanding of its pathogenesis this study aims to identify proteins differentially expressed in a pool of five viremic plasma from severe dengue patients relative to a pool of five non-severe dengue patients. Results The use of Isotope Coded Protein Labeling (ICPLTM to analyze plasma depleted of twenty high-abundance proteins allowed for the identification of 51 differentially expressed proteins, which were characterized by mass spectrometry. Using quantitative ELISA, three of these proteins (Leucine-rich glycoprotein 1, Vitamin D binding-protein and Ferritin were confirmed as having an increased expression in a panel of severe dengue plasma. The proteins identified as overexpressed by ICPLTM in severe dengue plasma involve in clear up action after cell injury, tissue coherence and immune defense. Conclusion This ICPLTM study evaluating differences between acute severe dengue plasmas and acute non-severe dengue plasmas suggests that the three proteins identified are overexpressed early in the course of the disease. Their possible use as biomarkers for the prognostic of disease severity is discussed.

  2. Does the Duration of Abdominal Pain Prior to Admission Influence the Severity of Acute Pancreatitis?

    2013-03-01

    Full Text Available Context In a prior report involving patients with hemoconcentration at admission, those with necrotizing pancreatitis presented significantly earlier than those with interstitial disease suggesting that duration of abdominal pain prior to presentation may have prognostic significance in acute pancreatitis. Objectives The aim of the present study was to determine whether the duration of abdominal pain prior to admission influences the severity of acute pancreatitis. Methods During a five-year period, all patients presenting directly to our hospital with their first episode of acute pancreatitis were enrolled in a cohort study. We analyzed data obtained from records of all such patients and performed a separate analysis on those with hemoconcentration (hematocrit equal to, or greater than, 44% at presentation to determine whether duration of abdominal pain prior to presentation was associated with severity of acute pancreatitis. Duration of abdominal pain wascategorized as persisting for either less than 12 h or 12 h or more prior to arrival. Prognostic markers of severity included admission hematocrit and blood urea nitrogen (BUN, as well as the development of systemic inflammatory response syndrome (SIRS during the initial 24 h of hospitalization. Outcome measures included pancreatic necrosis based on contrast-enhanced CT scanning, need for intensive care, length of hospitalization, and death. Radiologic severity of peripancreatic inflammatory changes was assessed within 48 h of admission in accordance with the Balthazar-Ranson scoring system (A-E. Results Among a total of 318 patients, there were 62 (19.5% with hemoconcentration at admission. Among the 318 patients, there was no significant difference in the prevalence of pancreatic necrosis when comparing the less than 12 h group to the 12 h or more group. Among the 62 patients with hemoconcentration, those admitted within 12 h compared to those admitted 12 h or more following the onset of

  3. Enhanced multidetector-row computed tomography (MDCT) in the diagnosis of acute appendicitis and its severity

    The purpose of this study was to examine the accuracy of enhanced multidetector-row computed tomography (MDCT) in diagnosing acute appendicitis and its severity. Contrast-enhanced MD-CT 3.5 mm thick images of 23 control patients (A), and 64 patients with surgically proven acute appendicitis including 8 catarrhal (B), 28 phiegmonous (C), and 28 gangrenous (D) appendicitis patients were respectively analyzed. The number of observed major computed tomography (CT) findings for each patient group were as follows: enlarged (≥6 mm in maximum diameter) appendix (A: 5, B: 8, C: 28, D: 28), enhancement of the appendiceal wall; hyper (A: 3, B: 8, C: 27, D: 20), iso (A: 15, B: 0, C: 1, D: 2), hypo (A-C: 0, D: 4), and patched (A-C: 0, D: 2) enhancement, appendicolith (A, B: 0, C: 7, D: 13), dirty fat sign (A: 3, B: 1, C: 21, D: 28), localized ascites (A: 2, B: 0, C: 2, D: 11), and abscess formation (A-C: 0, D: 5). From the combinations of these findings, we could differentiate acute appendicitis from the control normal appendix with an accuracy of 99% and could diagnose the severity of acute appendicitis with accuracies of 92% for catarrhal appendicitis, 84% for phlegmonous appendicitis, and 92% for gangrenous appendicitis. We could also visually reconstruct the entire forms and positions of the appendices from the successive CT findings because of the high-resolution thin-slice MDCT images. MDCT is highly accurate in the diagnosis of acute appendicitis and its severity. (author)

  4. Luminal lactate in acute pancreatitis - validation and relation to disease severity

    Pynnönen Lauri

    2012-04-01

    Full Text Available Abstract Background Increased rectal luminal lactate concentration may be associated with the severity of the septic shock and high dose of vasopressors. It suggests hypoperfusion of the gut mucosa. This is potentially associated with bacterial translocation from the gut leading to local and systemic inflammation. In acute pancreatitis (AP bacterial translocation is considered as the key event leading to infection of necrotic pancreatic tissue and high severity of illness. Methods We used rectal luminal equilibration dialysis for the measurement of gut luminal lactate in 30 consecutive patients admitted to hospital due to acute pancreatitis to test the hypothesis that a single measurement of rectal luminal lactate predicts the severity of acute pancreatitis, the length of hospital stay, the need of intensive care and ultimately, mortality. We also tested the physiological validity of luminal lactate concentration by comparing it to luminal partial tension of oxygen. Additionally, a comparison between two different L-lactate analyzers was performed. Results High rectal luminal lactate was associated with low mucosal partial tension of oxygen (R = 0.57, p = 0.005 thereby indicating the physiological validity of the method. Rectal luminal lactate at the hospital admission was not associated with the first day or the highest SOFA score, CRP level, hospital length of stay, length of stay in intensive care or mortality. In this cohort of unselected consecutive patients with acute pancreatitis we observed a tendency of increased rectal lactate in the severe cases. Low precision and high bias was observed between two lactate analyzers. Conclusions The association between rectal luminal lactate and oxygen tension indicates that luminal lactate is a marker mucosal anaerobiosis. Comparison between two different analyzers showed poor, non-constant precision over the range of lactate concentrations. Rectal luminal lactate concentration at the time of

    AIM:To analyze the prognostic value of adipokines in predicting the course,complications and fatal outcome of acute pancreatitis (AP).METHODS:We performed the search of PubMed database and the systemic analysis of the literature for both experimental and human studies on prognostic value of adipokines in AP for period 2002-2012.Only the papers that described the use of adipokines for prediction of severity and/or complications of AP were selected for further analysis.Each article had to contain information about the levels of measured adipokines,diagnosis and verification of AP,to specify presence of pancreatic necrosis,organ dysfunction and/or mortality rates.From the very beginning,study was carried out adhering to the PRISMA checklist and flowchart for systemic reviews.To assess quality of all included human studies,the Quality Assessment of Diagnostic Accuracy Studies tool was used.Because of the high heterogeneity between the studies,it was decided to refrain from the statistical processing or meta-analysis of the available data.RESULTS:Nine human and three experimental studies were included into review.In experimental studies significant differences between leptin concentrations at 24 and 48 h in control,acute edematous and acute necrotizing pancreatitis groups were found (P =0.027 and P < 0.001).In human studies significant differences between leptin and resitin concentrations in control and acute pancreatitis groups were found.1-3 d serum adiponectin threshold of 4.5 μg/mL correctly classified the severity of 81% of patients with AR This threshold yielded a sensitivity of 70%,specificity 85%,positive predictive value 64%,negative predictive value88% (area under curve 0.75).Resistin and visfatin concentrations differ significantly between mild and severe acute pancreatitis groups,they correlate with severity of disease,need for interventions and outcome.Both adipokines are good markers for parapancreatic necrosis and the cut-off values of 11

    Radiation accidents or terrorist attacks can result in serious consequences for the civilian population and for military personnel responding to such emergencies. The early medical management situation requires quantitative indications for early initiation of cytokine therapy in individuals exposed to life-threatening radiation doses and effective triage tools for first responders in mass-casualty radiological incidents. Previously established animal (Mus musculus, Macaca mulatta) total-body irradiation (γ-exposure) models have evaluated a panel of radiation-responsive proteins that, together with peripheral blood cell counts, create a multiparametic dose-predictive algorithm with a threshold for detection of ~1 Gy from 1 to 7 d after exposure as well as demonstrate the acute radiation syndrome severity score systems created similar to the Medical Treatment Protocols for Radiation Accident Victims developed by Fliedner and colleagues. The authors present a further demonstration of the acute radiation sickness severity score system in a mouse (CD2F1, males) TBI model (1-14 Gy, Co γ-rays at 0.6 Gy min) based on multiple biodosimetric endpoints. This includes the acute radiation sickness severity Observational Grading System, survival rate, weight changes, temperature, peripheral blood cell counts and radiation-responsive protein expression profile: Flt-3 ligand, interleukin 6, granulocyte-colony stimulating factor, thrombopoietin, erythropoietin, and serum amyloid A. Results show that use of the multiple-parameter severity score system facilitates identification of animals requiring enhanced monitoring after irradiation and that proteomics are a complementary approach to conventional biodosimetry for early assessment of radiation exposure, enhancing accuracy and discrimination index for acute radiation sickness response categories and early prediction of outcome.

  10. The effectiveness of interventions to treat severe acute malnutrition in young children: a systematic review

    Picot, Joanna; Hartwell, Debbie; Harris, P; Mendes, Diana; Clegg, Andrew; Takeda, Andrea

    2012-01-01

    Severe acute malnutrition (SAM) arises as a consequence of a sudden period of food shortage and is associated with loss of a person’s body fat and wasting of their skeletal muscle. Many of those affected are already undernourished and are often susceptible to disease. Infants and young children are the most vulnerable as they require extra nutrition for growth and development, have comparatively limited energy reserves and depend on others. Undernutrition can have drastic and wide-ranging con...

    2014-01-01

    Myeloproliferative neoplasms transformed into AML usually have a poor prognosis. We report a case of essential thrombocythemia with myelofibrosis that transformed into acute promyelocytic leukemia (APL) with both the t(15;17) translocation as well as the JAK2 V617F mutation. Clinically, this case was notable for severe differentiation syndrome despite treatment with high-dose dexamethasone. Cytokine production by differentiating APL cells was not directly abrogated by JAK2 inhibitors in vitro...

Clinical and laboratory evaluation revealed that the child also had hypopigmented hair and skin, splenohepatomegaly, pancytopenia and hypoalbuminaemia. The coexistence of hypopigmentation and suspected low immunity prompted us t...

  14. Managing severe acute respiratory syndrome (SARS) intellectual property rights: the possible role of patent pooling.

    2005-01-01

    Patent applications that incorporate the genomic sequence of the severe acute respiratory syndrome (SARS) coronavirus, have been filed by a number of organizations. This is likely to result in a fragmentation of intellectual property (IP) rights which in turn may adversely affect the development of products, such as vaccines, to combat SARS. Placing these patent rights into a patent pool to be licensed on a non-exclusive basis may circumvent these difficulties and set a key precedent for the ...

    2014-01-01

    Background: The use of corticosteroid in the management of severe acute pancreatitis (SAP) remains contentious and is still being debated despite many pre-clinical studies demonstrating benefits. The limitations of clinical research on corticosteroid in SAP are disparities with regard to benefit, a lack of adequate safety data and insufficient understanding of its mechanisms of action. Thus, we performed a meta-analysis to assess the effectiveness of corticosteroid in experimental SAP and tak...

    Severe acute pancreatitis is a clinical entity that can develop into multiple organ failure (MOF), and still has a poor prognosis. It is generally agreed that excessive humoral mediators such as pro-inflammatory cytokines play important roles in the pathogenesis of organ failure in patients with severe acute pancreatitis (SAP). Furthermore, it has been reported that continuous hemodiafiltration (CHDF) can remove the excess humoral mediators during the hypercytokinemic state of systemic inflammatory response syndrome (SIRS). We experienced a case of severe acute pancreatitis induced by alcohol abuse, on whom we performed cytokine apheresis. The patient was a 46 year-old male. He received 14 cytokine apheresis procedures, for about 4 hours in each session, using a CTR-001 direct hemoperfusion (DHP) cartridge. His serum levels of pro-inflammatory cytokines such as interleukin-6 (IL-6; 1649.1+/-667.1-1257.1+/-489.4 pg/mL, P=0.013) decreased significantly after the CTR-001 procedures. However tumor necrosis factor-alpha (TNF-alpha) (26.2+/-1.7-24.3+/-1.9 pg/mL, P=0.087), IL-1beta (6.1+/-2.9-3.49+/-1.1 pg/mL, P=0.477), IL-8 (192.5+/-33.4-229.5+/-51.8 pg/mL, P=0.754) and IL-10 (14.4+/-2.7-14.0+/-1.9 pg/mL, P=0.726) did not decrease statistically. Therefore, we conclude that in this case, cytokine apheresis using a CTR-001 cartridge was effective for reducing the pro-inflammatory cytokines during severe acute pancreatitis. PMID:16076384
