BACKGROUND: Duchenne muscle dystrophy (DMD) is one of the most common lethal genetic diseases of children worldwide and is 100% fatal. Steroids, the only therapy currently available, are marred by poor efficacy and a high side-effect profile. New therapeutic approaches are urgently needed. METHODS: Here, we leverage PGC-1α, a powerful transcriptional coactivator known to protect against dystrophy in the mdx murine model of DMD, to search for novel mechanisms of protection against dystrophy...

Pneumonia remains a leading cause of morbidity and mortality in developing countries. Comprehensive surveillance data are needed to review the prevention and control strategies. We conducted active surveillance of acute lower respiratory infections among children aged <2 years hospitalized at two hospitals of Islamabad, Pakistan. Viral etiology was determined using real-time PCR on respiratory specimens collected during March 2011-April 2012. The overall mean age was 7.83 ± 5.25 months while no statistical difference between age or sex distribution of patients with positive and negative viral etiology (p > 0...

To our knowledge, there are no previous reports of apple allergy with systemic symptoms for which repeated oral food challenges were performed over a long follow-up. The patient was an 8-year-old boy with hay fever. He visited our hospital because of nasal drop, itchy eyes, and dyspnea after lunch every two months for 2 years. Apple allergy was suspected through his medical interview and specific immunoglobulin (Ig) E levels, and he consequently underwent an oral food challenge test. Ninety minutes after ingestion of one whole apple, he experienced coughing, nasal drop, eyelid edema, and conjunctival injection...

BACKGROUND: The efficacy of inhaled corticosteroids (ICSs)/long-acting beta2-agonist (LABA) treatment in patients with asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) compared to patients with COPD alone has rarely been examined. This study aimed to evaluate the clinical efficacy for the improvement of lung function after ICS/LABA treatment in patients with ACOS compared to COPD alone patients. METHODS: Patients with stable COPD were selected from the Korean Obstructive Lung Disease (KOLD) cohort...

Piyush Mehta
Administration of drug molecules by inhalation route for treatment of respiratory diseases has the ability to deliver drugs, hormones, nucleic acids, steroids, proteins, and peptides, particularly to the site of action, improving the efficacy of the treatment and consequently lessening adverse effects of the treatment. Numerous inhalation delivery systems have been developed and studied to treat respiratory diseases such as asthma, COPD, and other pulmonary infections. The progress of disciplines such as biomaterials science, nanotechnology, particle engineering, molecular biology, and cell biology permits further improvement of the treatment capability...

Background. We assessed vitamin D intakes and serum 25(OH) vitamin D levels in pediatric asthma patients on moderate-to-high dose inhaled steroids and compared them to published findings of healthy children in our city. Methods. Parents and/or patients were interviewed to estimate the children's vitamin D intakes from foods and supplements (using an adapted validated food frequency questionnaire) and asthma duration and management. Vitamin D status: serum 25-hyroxy vitamin D (25(OH)D) was obtained from the medical records...

Therapeutic hypothermia was associated with increased mortality in patients with severe bacterial meningitis in a large randomized trial. It still remains a treatment strategy for comatose survivors of cardiac arrest. There are several potential advantages of inhalational anesthetics as long-term sedation agents compared to intravenous sedation, however, uncontrollable increases of intracranial pressure were observed in neurocritical patients. Here we present a patient with severe bacterial meningitis and secondary cardiac arrest where therapeutic hypothermia and inhalational anesthesia were successfully used...

BACKGROUND: Steroid resistant (SR) asthma is characterized by persistent airway inflammation that fails to resolve despite treatment with high doses of corticosteroids. Furthermore, SR patient airways show increased numbers neutrophils, which are less responsive to glucocorticoid. The present study seeks to determine whether dexamethasone (DEX) has different effect on neutrophils from steroid sensitive (SS) asthmatics compared to SR asthmatics. METHODS: Adults with asthma (n = 38) were classified as SR or SS based on changes in lung FEV1% following a one-month inhaled corticosteroid (ICS) treatment...

Asthma is a very frequent disease with complex and heterogenous immunological and clinical features. Daily inhaled steroids are the cornerstone of the current therapeutics sometimes associated with long-acting β2-agonist. This controller treatment is effective and allows to control asthma symptoms for the vast majority of the patients. Severe asthma is characterized by a poor level of control of symptoms, with recurrent exacerbations or a chronic airflow limitation despite an optimal management. Severe asthma remains a difficult diagnosis but we have now studies proving the clinical efficacy or promising data about monoclonal antibodies targeting IgE, IL-5, IL-4 or IL-13...

Severe asthma is a discrete clinical entity characterised by recurrent exacerbations, reduced quality of life and poor asthma control as ordinary treatment regimens remain inadequate. Difficulty in managing severe asthma derives partly from the multiple existing phenotypes and our inability to recognise them. Though the exact pathogenetic pathway of severe allergic asthma remains unclear, it is known that numerous inflammatory cells and cytokines are involved, and eosinophils represent a key inflammatory cell mediator...

Bronchiolitis obliterans (BO) is the most remarkable pulmonary sequels of war-related sulfur mustard inhalation. There is little if any data about long-term efficacy of associated BO treatment. Five years spirometric records of three groups of patients with obstructive pulmonary diseases (asthma, COPD, BO) and documented sulfur mustard inhalation were evaluated. The BO patients were treated with inhaled Seretide 125-250/25 (2 puffs BID), azithromycin (250 mg, three times/week) and N-acetylcysteine (1200-1800/day)...

As one of the candidates of the therapeutic strategy for asthma in addition to inhaled corticosteroids (ICS), leukotriene receptor antagonists (LTRAs) are known to be useful for long-term management of asthma patients complicated by allergic rhinitis (AR) or exercise-induced asthma (EIA). Currently available LTRAs are pranlukast hydrate, zafirlukast, and montelukast. These LTRAs have a bronchodilator action and inhibit airway inflammation, resulting in a significant improvement of asthma symptoms, respiratory function, inhalation frequency of as-needed inhaled β2-agonist, airway inflammation, airway hyperresponsiveness, dosage of ICSs, asthma exacerbations, and patients' QOL...

PURPOSE OF REVIEW: Severe asthma is a heterogeneous syndrome that can be classified into distinct phenotypes and endotypes. In the type 2 (T2)-high endotype, multiple cytokines are produced that lead to eosinophilic inflammation. These cytokines and their receptors are targets for biologic therapies in patients with severe asthma who do not respond well to standard therapy with inhaled corticosteroids. RECENT FINDINGS: In the last decade, an increasing number of biologic therapies have been developed targeting T2 inflammation...

BACKGROUND: Suboptimal adherence to inhaled steroids is common in children with asthma and is associated with poor disease control, reduced quality of life and even death. Previous studies using feedback of electronically monitored adherence data have demonstrated improved adherence, but have not demonstrated a significant impact on clinical outcomes. The aim of this study was to determine whether introduction of this approach into routine practice would result in improved clinical outcomes...

In many countries, short-acting β2-agonist inhalers have traditionally been coloured blue. This inhaled therapy has also conventionally been known as a 'reliever' by patients and healthcare professionals (HCPs), in comparison with 'preventer' medications (inhaled steroids). With the rapidly changing market in inhaled therapy for COPD and asthma and growing numbers of devices, there has been some concern that the erosion of traditional colour conventions is leading to patients (and HCPs) becoming confused about the role of different therapies...

INTRODUCTION: Prolonged use of systemic corticosteroids leads to reduced bone mineral density and osteoporosis, in turn increasing the risk of minimal trauma fractures with their associated morbidity and mortality in elderly populations. However, the effect of inhaled corticosteroids on bone mineral density has been debated in the medical literature. OBJECTIVES: We aimed to determine the effect of inhaled corticosteroids on bone mineral density measured using calcaneal quantitative ultrasonography in a cohort of older Australians...
