What is COPD or pulmonary fibrosis worse?

The epidemiology of IPF has been difficult to study, as it is a relatively rare disease with evolving diagnostic criteria. Reported prevalence and incidence for IPF vary and depend on reporting methods. IPF is often not diagnosed until permanent lung scarring occurs. Many people with COPD have only mild symptoms and are not diagnosed until their disease has progressed further.

There is currently no cure for IPF or COPD. They may also be combined with inhaled steroids, depending on the severity of COPD symptoms and the number of COPD outbreaks. Oral corticosteroids are prescribed for short-term use only and are used primarily for COPD and not for IPF. Other surgeries may be used to help relieve the symptoms of COPD, depending on the type of lung damage that has occurred.

In a bullectomy, the enlarged air spaces in the air sacs, called bullae, may be removed to help you breathe. In lung volume reduction surgery, damaged lung tissue may be removed to help improve breathing. Both IPF and COPD are life-threatening diseases, so early detection is key. If you have any of the known symptoms, get an immediate evaluation.

Once you're diagnosed, sticking to your treatment plan can help extend your life. No, pulmonary fibrosis and chronic obstructive pulmonary disease (COPD) are not the same thing. However, they are similar in some respects. Pulmonary fibrosis and COPD are lung diseases that get worse over time.

Both conditions can make it difficult to breathe. Pulmonary hypertension (PH) can occur in people who have chronic lung diseases, such as COPD (chronic obstructive pulmonary disease) or idiopathic pulmonary fibrosis (IPF). COPD and pulmonary fibrosis are chronic lung diseases that make it difficult for a person to breathe. However, these two diseases cause different types of lung damage and have different causes.

IPF is the accumulation of scar tissue in the lungs, making it difficult for patients to breathe. In IPF, the cause is unknown. IPF causes permanent and irreversible lung scars. Treatments for PH with IPF work to slow disease progression and improve quality of life.

Chronic lung disease in any form can often be a debilitating affliction, which dramatically affects the quality of life, energy levels and even appearance. Respiratory diseases are a growing concern not only among Americans but also in the world at large. For many, chronic obstructive pulmonary disease (COPD) is often the most prevalent. However, although pulmonary fibrosis may be less common, its effects are generally fatal.

Although both diseases can be experienced simultaneously, the two diseases are drastically different in a variety of ways. Combined pulmonary fibrosis and emphysema (CPFE) is a disease characterized by both centrilobular emphysema (usually in the upper lobes) and fibrosis (typically in the lower lobes) (Figure. CPFE is thought to be different from idiopathic pulmonary fibrosis (IPF) and chronic obstructive pulmonary disease (COPD). Patients with CPFE tend to be older men with a significant history of smoking.

This disease is clinically important because of the increased risk of lung cancer and poor overall survival. There is increasing clinical, radiological and pathological recognition of the coexistence of emphysema and pulmonary fibrosis in the same patient, resulting in a clinical syndrome known as combined pulmonary fibrosis and emphysema (CPFE) characterized by dyspnea, upper lobe emphysema, lower lobe fibrosis, and abnormalities of the gas exchange. This syndrome is often complicated by pulmonary hypertension, acute lung injury, and lung cancer. CPFE syndrome typically occurs in male smokers, and mortality associated with this condition, especially if pulmonary hypertension is present, is significant.

In this review, we explore the current state of the literature and discuss the etiological factors and clinical characteristics of CPFE syndrome. Emphysema and pulmonary fibrosis have different physiological effects. Emphysema causes reduced pulmonary elastic recoil, increased pulmonary compliance and increased lung volumes with reduced peak expiratory flow rates, while pulmonary fibrosis results in increased pulmonary elastic recoil, decreased pulmonary compliance and reduced pulmonary conformity. lung volumes with a maximum preserved or even increased expiratory flow rates at a given lung volume.

Clinically, emphysema or fibrosis typically predominate, and individual patients are rarely recognized as having both disorders simultaneously. However, the pathological changes of co-existing emphysema and fibrosis are common in smokers, 1,2 Pulmonary fibrosis may not be seen in patients with advanced emphysema, and patients with a combination of pulmonary emphysema and other pulmonary parenchymal diseases may be at increased risk of postoperative complications, 3 Patients with pulmonary fibrosis and emphysema have different pulmonary function tests (PFT) and results than patients with pure emphysema or pure fibrosis. Therefore, the traditional clinical dichotomy between emphysema and pulmonary fibrosis and the limitation of traditional diagnostic tests used to identify the simultaneous occurrence of these disorders may result in an underestimation of the frequent coexistence of these entities in individual patients. It is not yet clear whether CPFE represents a single pathological entity or a coincidence of two lung diseases related to cigarette smoking.

In this review, we explore the current state of the literature on CPFE and discuss the etiological factors and clinical characteristics of CPFE. Data are presented as mean ± SD or SE, unless otherwise indicated. Pulmonary fibrosis and emphysema combined with CPFE %3D; NA %3D not available. Emphysema has been reported to be more common in male smokers than in female smokers, 38 Most studies on sex and emphysema have focused on the relative extent of emphysema in men and women, with slightly more extensive emphysema in male smokers on CT imaging, 39,40 However, these small differences in the extent of emphysema do not clearly indicate the basis for the significant male preponderance of CPFE cases.

We speculate that men are more susceptible to smoking-induced emphysema and pulmonary fibrosis due to increased vulnerability to abnormal lung aging in men. Both emphysema and pulmonary fibrosis are associated with chronological aging. In an autopsy study of smokers and non-smokers, the burden of both emphysema and pulmonary fibrosis increased with increasing chronological age, while smoking synergistically increased these effects in each age group, 1 Both COPD and pulmonary fibrosis have been associated with shortening telomere length, to biological marker of aging of research interest, 44,45 Future research into the pathogenesis of CPFE should include the evaluation of lung tissue samples for biological markers of aging, such as telomere length. Emphysema occurs in people with asbestosis.

In the RCT screening studies of patients with asbestosis, emphysema was present in 10% to 36%. Characteristic radiological findings in CPFE syndrome include emphysema of the upper lobe and interstitial fibrotic changes in the lower lobe (Fig. Emphysema in CPFE includes bullous, paraseptal and centrilobular changes 7,13,25 and is typically distributed in the upper lobes, 7.25 Kitaguchi et al25 found that paraseptal emphysema was more common in the CPFE population than in a control group of COPD patients (33.3% vs. 8.5%, respectively).

Honeycomb and reticular abnormalities are common, but areas of frosted glass attenuation are also present, as in 66% of subjects with CPFE in a series by Cottin et al., 7 Occasionally, frosted glass attenuation is the exclusive anomaly suggesting the possibility of interstitial lung disease, and in this context, biopsy is essential, 9 Because smoking is nearly universal in reported cases of CPFE, frosted glass attenuation may be indicative of smoking-related interstitial lung diseases such as interstitial desquamative pneumonia. Incidental lung nodules or masses can be found in patients with CPFE because the prevalence of lung cancer in this population appears to be high, 25,68.The overall sensitivity of CT imaging, including SCT images, for findings consistent with CPFE is unclear and may not be high when comparing pathological findings with imaging, 2 More sensitive imaging techniques may be needed to diagnose small regions of CPFE in populations at risk, but the clinical significance of small regions of emphysema and fibrosis is currently unknown. A variety of pathological patterns of pulmonary fibrosis along with emphysema have been reported in CPFE syndrome, including common interstitial pneumonia7, enlarged airspace with fibrosis,69 nonspecific interstitial pneumonia,7 interstitial lung disease associated with respiratory bronchiolitis with septal fibrosis alveolar,70 desquamative interstitial pneumonia with extensive fibrosis,9 and smoking-related unclassifiable interstitial fibrosis, 2 The importance of changes in lung function over time seems to differ in patients with isolated IPF compared to patients with CPFE syndrome. Akagi et al18 reported that patients with CPFE experience a slower decline in FVC and DLCO over time than patients with isolated IPF.

Because the decrease in FVC and DLCO are important prognostic factors in IPF, the lack of recognition of concomitant emphysema in these patients can cause errors in prognosis. This was highlighted by Schmidt et al,16 who found that longitudinal decline in FEV1 was more predictive of mortality in CPFE patients than other lung function parameters or a composite physiological index, while a composite physiological index was a better predictor of mortality in the isolated IPF group. Mortality in patients with CPFE syndrome is significant (Table. The median survival in the reported series ranged from 2.1 to 8.5 years, excluding a series by Usui et al34 in which all patients had previously received a diagnosis of lung cancer.

If there is pulmonary hypertension confirmed by right cardiac catheterization, 1-year survival is only 60%. A study by Mejía et al15 found worse survival in a group with both emphysema and IPF compared to a group with isolated IPF, a finding related to pulmonary hypertension. Interestingly, the group with emphysema and IPF described by Mejía et al15 had lower vital capacities than other reported cases of CPFE syndrome (Table), and may not reflect the typical patient with CPFE syndrome. Unlike the results of Mejía et al,15 other studies12‐14,17,18 have found comparable or better survival in CPFE cohorts than in groups with isolated pulmonary fibrosis.

The basis for these contradictory results is unclear and may include the relative proportion of non-FPI pathology in patients with CPFE syndrome in individual studies,13,17 influence of emphysema subtypes, 17 retrospective study design,13,15 inclusion and exclusion criteria,14 and selection of control groups. However, these results raise important questions about whether patients with characteristics of CPFE syndrome should be included in IPF6 therapy trials, as they may not share the same pathogenic factors or natural history as patients with IPF. A better understanding of the natural history of CPFE syndrome is needed based on prospective cohort studies, as these patients may not benefit or be harmed by therapies developed specifically for IPF. Subgroup analysis of completed IPF pharmacotherapy trials, stratified by the presence or absence of emphysema, may be informative.

Patients with CPFE may have a significantly higher risk of lung cancer. Odani et al68 found prevalent lung cancer in 13 out of 31 (42%) cases of CPFE. Kitaguchi et al25 also found a significant increase in the prevalence of lung cancer in a cohort with CPFE compared to a cohort with COPD alone (46.8% vs. 7.3%, respectively), although this outcome may be affected by referral bias in a lung cancer treatment center.

Kurashima et al14 found a significantly higher proportion of lung cancer deaths in a CPFE cohort (12 out of 36 deaths, 33.3%) compared to a cohort with IPF alone (eight out of 66 deaths, 12.1%). In a large cohort with lung cancer, Usui et al34 found that CPFE was a significantly more frequent imaging finding (101 out of 1,143 patients, 8.9%) than isolated pulmonary fibrosis (15 out of 1,143 patients, 1.3%). Survival was significantly worse for CPFE and lung cancer than for emphysema and lung cancer, 34 These results need to be replicated in more diverse patient populations in other centers. However, they suggest that chronic lung injury that occurs in CPFE may influence the development and progression of lung cancer, which may be linked to the “triple effects” of smoking, emphysema, and pulmonary fibrosis, all factors associated with the development of lung cancer, in CPFE.

In addition, an oncogene-based predisposition to the development of CPFE syndrome is possible. COPD is a lung disease in which chronic inflammation causes frequent coughing, mucus production, and an increased risk of infection. This type of chronic inflammation can significantly worsen the scarring of the lungs (caused by pulmonary fibrosis). The Centers for Disease Control and Prevention (CDC) claims that 16 million Americans have COPD, and the American Lung Association reports that more than 16.4 million have been diagnosed.

In COPD, the airways, which are branched tubes that carry air into the lungs, become narrowed and damaged. For example, joining a support group can provide you with a space to discuss the challenges of IPF or COPD and find resources to help you cope. However, early detection of the disease is key to slowing progression, and conditions such as chronic obstructive pulmonary disease (COPD) or pulmonary arterial hypertension (PAH) can affect the prognosis of the disease. Chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis (also called idiopathic pulmonary fibrosis or IPF) are serious, lifelong illnesses that make breathing difficult.

Combined pulmonary fibrosis and emphysema, CPFE; chronic obstructive pulmonary disease, COPD; idiopathic pulmonary fibrosis, IPF; usual interstitial pneumonitis, NIU; CT scan, CT. Compared to COPD, pulmonary fibrosis is not always related to smoke or other inhalants, and in some cases it can occur as a result of a genetic predisposition to the disease. If you or a loved one has COPD or other lung disease, the Lung Health Institute can help you with a variety of cellular treatment options. In COPD, also known as chronic bronchitis, the airways and sacs of the lungs become blocked and make it difficult to breathe.

The Pulmonary Health Institute is here to inform and train, and with your health in mind, we'll look at the difference between COPD and pulmonary fibrosis, and what you can do about it. . .
