Anti Inflammatory

Chronic respiratory diseases are the third leading cause of death, behind cardiovascular diseases and cancer, affecting approximately 550 million of people all over the world. Most of the chronic respiratory diseases are attributable to asthma and chronic obstructive pulmonary disease (COPD) with this latter being the major cause of deaths. Despite differences in etiology and symptoms, a common feature of asthma and COPD is an underlying degree of airways inflammation. The nature and severity of this inflammation might differ between and within different respiratory conditions and pharmacological anti-inflammatory treatments are unlikely to be effective in all patients. A precision medicine approach is needed to selectively target patients to increase the chance of therapeutic success. Inhibitors of the phosphodiesterase 4 (PDE4) enzyme like the oral PDE4 inhibitor roflumilast have shown a potential to reduce inflammatory-mediated processes and the frequency of exacerbations in certain groups of COPD patients with a chronic bronchitis phenotype. However, roflumilast use is dampened by class related side effects as nausea, diarrhea, weight loss and abdominal pain, resulting in both substantial treatment discontinuation in clinical practice and withdrawal from clinical trials. This has prompted the search for PDE4 inhibitors to be given by inhalation to reduce the systemic exposure (and thus optimize the systemic safety) and maximize the therapeutic effect in the lung. Tanimilast (international non-proprietary name of CHF6001) is a novel highly potent and selective inhaled PDE4 inhibitor with proven anti-inflammatory properties in various inflammatory cells, including leukocytes derived from asthma and COPD patients, as well as in experimental rodent models of pulmonary inflammation. Inhaled tanimilast has reached phase III clinical development by showing promising pharmacodynamic results associated with a good tolerability and safety profile, with no evidence of PDE4 inhibitors class-related side effects. In this review we will discuss the main outcomes of preclinical and clinical studies conducted during tanimilast development, with particular emphasis on the characterization of the pharmacodynamic profile that led to the identification of target populations with increased therapeutic potential in inflammatory respiratory diseases.

Over the past two decades, a growing evidence base has emerged to support the benefits of pulmonary rehabilitation. It is now firmly established as a cornerstone of management in chronic obstructive pulmonary disease and other chronic respiratory diseases. This chapter describes the evidence base supporting the use of pulmonary rehabilitation, and the typical content of a pulmonary rehabilitation programme. As cardiovascular and respiratory diseases commonly exist, the effects and influence of cardiovascular disease on pulmonary rehabilitation are discussed. Finally, as there is growing interest to explore joint breathlessness rehabilitation services due to the symptomatic and functional similarities between chronic heart failure and chronic obstructive pulmonary disease, early work exploring the effects of pulmonary rehabilitation in chronic heart failure is described.

Abstract Interaction between a healthy microbiome and the immune system leads to body homeostasis, as dysbiosis in microbiome content and loss of diversity may result in disease development. Due to the ability of probiotics to help and modify microbiome constitution, probiotics are now widely used for the prevention and treatment of different gastrointestinal, inflammatory, and, more recently, respiratory diseases. In this regard, chronic respiratory diseases including chronic obstructive pulmonary disease (COPD), asthma and allergic rhinitis are among the most common and complicated respiratory diseases with no specific treatment until now. Accordingly, many studies have evaluated the therapeutic efficacy of probiotic administration (mostly via the oral route and much lesser nasal route) on chronic respiratory diseases. We tried to summarise and evaluate these studies to give a perspective of probiotic therapy via both the oral and nasal routes for respiratory infections (in general) and chronic respiratory diseases (specifically). We finally concluded that probiotics might be useful for allergic diseases. For asthmatic patients, probiotics can modulate serum cytokines and IgE and decrease eosinophilia, but with no significant reduction in clinical symptoms. For COPD, only limited studies were found with uncertain clinical efficacy. For intranasal administration, although some studies propose more efficiency than the oral route, more clinical evaluations are warranted.

Chronic Respiratory Diseases

Chronic respiratory diseases (CRDs) are an important factor of morbidity and mortality, accounting for approximately 6% of total deaths worldwide. The main CRDs are asthma and chronic obstructive pulmonary disease (COPD). These complex diseases have different triggers including allergens, pollutants, tobacco smoke, and other risk factors. It is important to highlight that although CRDs are incurable, various forms of treatment improve shortness of breath and quality of life. The search for tools that can ensure accurate diagnosis and treatment is crucial. MicroRNAs (miRNAs) are small non-coding RNAs and have been described as promising diagnostic and therapeutic biomarkers for CRDs. They are implicated in multiple processes of asthma and COPD, regulating pathways associated with inflammation, thereby showing that miRNAs are critical regulators of the immune response. Indeed, miRNAs have been found to be deregulated in several biofluids (sputum, bronchoalveolar lavage, and serum) and in both structural lung and immune cells of patients in comparison to healthy subjects, showing their potential role as biomarkers. Also, miRNAs play a part in the development or termination of histopathological changes and comorbidities, revealing the complexity of miRNA regulation and opening up new treatment possibilities. Finally, miRNAs have been proposed as prognostic tools in response to both conventional and biologic treatments for asthma or COPD, and miRNA-based treatment has emerged as a potential approach for clinical intervention in these respiratory diseases; however, this field is still in development. The present review applies a systems biology approach to the understanding of miRNA regulatory networks in asthma and COPD, summarizing their roles in pathophysiology, diagnosis, and treatment.

Leptin is one of the adipokines shown to exert a significant effect in respiratory diseases, including chronic obstructive pulmonary disease (COPD).The aim of the present study was to evaluate the possible role of serum leptin as biomarker in COPD.The serum leptin levels were assessed in 58 patents with stable COPD and 21 controls applying ELISA method.The leptin levels were higher, although not significantly, in COPD patients than in controls (221.52&plusmn;24.28(SE) vs. 165.04&plusmn;26.01 pg/ml, p=0.197). This tendency turned out significant when only females were compared (414.60&plusmn;60.63 vs. 219.40&plusmn;44.15 pg/ml, p=0.038). The levels of leptin were highly dependent on the BMI both in COPD patients (p<0.001) and in controls (p=0.024): they were the highest in obese individuals and decreased with reducing the BMI.In the COPD group, women had significantly higher leptin levels than men (p<0.0001) independent of the BMI. The non-smoking patients had significantly higher leptin levels than ex-smokers (p=0.007) and current smokers (p=0.007). In patients with BMI above 25, several associations were observed: patients with mild COPD had higher serum leptin level than those with severe or very severe COPD (p=0.038); the leptin levels correlated positively with FEV1% (r= 0.304, p=0.045) and FEV1/FVC ratio (I= 0.348, p=0.021), and tended to correlate negatively with ABCD GOLD groups (Rho=-0.300, p=0.043) and with the CAT points (Rho=-0.258, p=0.091); the leptin levels below 300 ng/ml determined 4.08-fold higher risk for more severe COPD.The results of our study confirm that the serum leptin levels depend significantly on the BMI and are interfered by gender and smoking habits. However, this adipokine cannot be used as a serum biomarker for distinguishing COPD patients, but its decrease might be associated with aggravation of the disease.
