This review explores the health and social burden of some of the main respiratory diseases (asthma, chronic obstructive pulmonary disease, cryptogenic fibrosing alveolitis, cystic fibrosis, lung cancer, mesothelioma, obstructive sleep apnoea and tuberculosis) in order to increase awareness of these diseases and highlight areas where improvements in care are required. The overall impact of respiratory diseases in the U.K. in terms of prevalence, mortality, morbidity and economic costs, with particular reference to secondary care has been considered and comparisons made with the rest of Europe where data are available. Respiratory diseases are responsible for a significant proportion of serious morbidity and premature death among the population of the U.K. and they will continue to present a growing challenge; special support is needed to tackle this burden.

Idiopathic pulmonary fibrosis (IPF) is a chronic and usually fatal lung disease of unknown etiology. The aim of this study was to describe clinical and polysomnographic features of sleep-related breathing disorders (SRBD) and to identify predictors of obstructive sleep apnea (OSA) in IPF patients. Eight hundred fifty-seven patients with IPF were admitted to the Cleveland Clinic from 2001 to 2005. An all-night polysomnogram (PSG) was performed in 18 of them to investigate complaints suggestive of sleep-disordered breathing. OSA was confirmed in 11 of the 18 IPF patients with complaints suggestive of sleep apnea, while the remain 7 patients had a diagnosis of primary snoring or upper airway resistance syndrome (UARS). All patients showed a reduction in sleep efficiency, REM sleep, and slow wave sleep. The apnea-hypopnea index (AHI) was positively correlated with body mass index (p < 0.0001, r = 0.80). The REM AHI and overall AHI were negatively correlated with FEV(1) (p = 0.008, r = -0.59 and p = 0.04, r = -0.49, respectively) and FVC percentages (p = 0.03, r = -0.50 and p = 0.08, r = -0.42, respectively). Our study is the first describing SRBD in IPF patients. An increased BMI and a significant impairment in pulmonary function testing may be predictors of OSA in this population. In the absence of effective treatments for IPF, the diagnosis and treatment of comorbid SRBD may lead to improvements in quality of life.

The complex nature of interactions between the pulmonary and cardiovascular systems is becoming increasingly appreciated. Pulmonary vascular abnormalities are frequently present in patients with respiratory disorders, including chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, sarcoidosis, neuromuscular or chest wall disorders, and disorders of ventilatory control including sleep apnea syndromes and obesity hypoventilation syndrome. Pulmonary hypertension, classified as group III in the World Health Organization classification scheme for pulmonary hypertension, may result in severe right ventricular dysfunction caused by lung disease, also known as cor pulmonale. The development of cor pulmonale is generally associated with poorer prognosis and increased death. Systemic manifestations of lung disease, particularly obstructive disorders, are also particularly relevant because they are associated with increased cardiac death and impaired health status. This article will discuss the most common pulmonary diseases and disorders of ventilatory control that cause pulmonary vascular abnormalities and cor pulmonale, with particular concentration on how treatment of these diseases may affect the heart. In addition, the complex nature of cardiac and lung disease will also be explored, particularly with respect to the relationship between chronic obstructive pulmonary disease, systemic inflammation, atherosclerosis, and cardiovascular death, which is currently a very active focus of research.

The outcome of patients with idiopathic pulmonary fibrosis (IPF), which represents the most common type of idiopathic pulmonary pneumonias, is poor. Breathlessness and coughing are usually progressive and about 50% of he patients die within 3 years after diagnosis. The effect of medical treatment in terms of survival is disappointing. Most of the currently available studies only focus on daytime diagnostics and therapy. The role of sleep quality and sleep disordered breathing in IPF is only investigated in a small number of papers, which can be summarized as follows: sleep fragmentation in IPF is very common. The reasons might be coughing, nocturnal oxygen desaturations, and increased respiratory drive. Sleep disorders in IPF have a profound impact on the quality of life. Oxygen desaturations often appear during sleep and can be predicted by the PaO(2) during wakefulness. There are no evidence-based recommendations concerning the indication for oxygen therapy and non-invasive ventilation during sleep in IPF. Obstructive sleep apnea (OSA) has no increased incidence with the exception of the IPF patients with an increased body mass index. If, however, OSA is present in IPF oxygen desaturations are more profound. The therapy of sleep disorders and sleep disordered breathing in IPF is individual. But in the absence of an effective treatment of IPF, optimization of sleep and life quality by the treatment of sleep disorders seems to be a primary goal. Further studies are needed to determine special sleep-related treatment effects.

Idiopathic pulmonary fibrosis (IPF) is a severe disease with a median survival time of only 24-36 months. It is characterized by inexorably progressive respiratory failure and by acute exacerbations that are often rapidly fatal. The standard treatment based on steroids and immunosuppressive drugs is no longer recommended Lung transplantation is the only treatment with an impact on survival but it concerns only a minority of patients and must be performed early in the disease process. Patients not eligible for transplantation should be given the opportunity to participate in clinical trials of promising new therapies. Many trials have recently been completed or are currently underway, but few results have been published. In the meantime, supportive treatment (oxygen therapy and rehabilitation), vaccination, and treatment of comorbidities (gastroesophageal reflux, sleep apnea) are recommended.

Idiopathic pulmonary fibrosis (IPF) is the most common interstitial lung disease. Despite progress made in understanding the pathophysiological mechanisms behind the development of the disease, its prognosis is poor. For this reason, any measure to improve the quality of life for these patients should be preferred. Some authors are interested in sleep disorders, and possible impact on quality of life. Patients with IPF have lowered scores of quality of life compared to those found in general population, with some correlation with the scores of sleep quality. There is a hyperfragmentation with many arousals and desaturation events. Some authors also report an apnea-hypopnea index higher in these patients, but these data are not found in all the studies. Correcting these obstructive phenomena may have a beneficial effect on survival, which would make systematic the sleep assessment in these patients. Finally, the relationship between IPF, gastroesophageal reflux and sleep apnea syndrome remains unclear.

Patients with interstitial lung disease commonly exhibit abnormal sleep architecture and increased sleep fragmentation on polysomnography. Fatigue is a frequent complaint, and it is likely that poor sleep quality is a significant contributor. A number of studies have shown that sleep disordered breathing is prevalent in this population, particularly in the idiopathic pulmonary fibrosis subgroup. The factors that predispose these patients to obstructive sleep apnoea are not well understood, however it is believed that reduced caudal traction on the upper airway can enhance collapsibility. Ventilatory control system instability may also be an important factor, particularly in those with increased chemo-responsiveness, and in hypoxic conditions. Transient, repetitive nocturnal oxygen desaturation is frequently observed in interstitial lung disease, both with and without associated obstructive apnoeas. There is increasing evidence that sleep-desaturation is associated with increased mortality, and may be important in the pathogenesis of pulmonary hypertension in this population.

The prevalence of obstructive sleep apnoea (OSA) is continuously increasing in patients with idiopathic pulmonary fibrosis (IPF) and, for the first time, the recent IPF guidelines recognise OSA as an important associated comorbidity that can affect patient's survival. Thus, it becomes conceivable that clinicians should refer patients with newly diagnosed IPF to sleep centres for the diagnosis and treatment of OSA as well as for addressing issues regarding the reduced compliance of patients with continuous positive airway pressure therapy. The discovery of biomarkers common to both disorders may help early diagnosis, institution of the most appropriate treatment and follow-up of patients. Better understanding of epigenetic changes may provide useful information about pathogenesis and, possibly, development of new drugs for a dismal disease like IPF.

Co-morbidities in idiopathic pulmonary fibrosis are common. These co-morbidities include obstructive sleep apnoea, gastro-oesophageal reflux disease, pulmonary hypertension and depression. The presence of co-morbidities among patients with idiopathic pulmonary fibrosis contributes to worse quality of life, morbidity and mortality. Despite the high prevalence of certain co-morbidities in idiopathic pulmonary fibrosis, the optimal screening and management of many of these conditions remains unclear. The impact of co-morbidities on this patient population is becoming more apparent. Their relevance will only increase as significant effort is being made to develop novel therapeutics that will alter the disease trajectory of patients with idiopathic pulmonary fibrosis. The purpose of this review is to focus on the epidemiology, pathophysiology, diagnosis and management of select co-morbidities, including obstructive sleep apnoea, gastro-oesophageal reflux disease, pulmonary hypertension and depression, in idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is associated with a fatal prognosis and manifests in patients over 60 years old who may have comorbidities. The prevalence and impact of comorbidities on the clinical course of IPF is unclear.This systematic literature review examined the prevalence of comorbidities and mortality associated with comorbidities in IPF patients. Relevant observational studies published in English from January 1990 to January 2015 identified via MEDLINE and EMBASE were included; bibliographies of articles were also searched.Among the 126 studies included, prevalence of pulmonary hypertension (PH) was 3-86%, 6-91% for obstructive sleep apnoea, 3-48% for lung cancer and 6-67% for chronic obstructive pulmonary disease (COPD). Nonrespiratory comorbidities included ischaemic heart disease (IHD) (3-68%) and gastro-oesophageal reflux (GER) (0-94%). Mortality was highest among patients with IPF and lung cancer. Most studies assessed relatively small samples of patients with IPF.PH, COPD, lung cancer, GER and IHD are significant comorbidities; differences in IPF severity, case definitions and patient characteristics limited the comparability of findings. The identification and prompt treatment of comorbidities may have a clinically significant impact on overall outcome that is meaningful for patients with IPF.
