Determinants of cough-related quality of life in interstitial lung diseases.

Background: Interstitial lung diseases (ILD) include a wide range of diseases impacting lung parenchyma and leading to fibrosis and architectural distortion. Chronic cough and dyspnea are common symptoms which affect the quality of life (QoL) in ILD patients. The mechanisms of cough in ILD patients are still unknown.

Characteristics of idiopathic pulmonary fibrosis -associated cough. a case-control study.

Background: Most patients with idiopathic pulmonary fibrosis (IPF) complain of cough. IPF-associated cough is widely characterized as dry or non-productive. The aim of this study was to compare chronic cough in early stage IPF patients to cough in subjects with chronic cough from a community-based sample and, especially, to investigate whether cough in IPF is less productive than chronic cough in a community-based sample.

Virtual communication is commonly used in Finnish interstitial lung disease multidisciplinary meetings.

Multidisciplinary meeting (MDM) is a core element in the diagnosis of interstitial lung diseases (ILD). The aim of the study was to investigate the implementation and key elements related to ILD MDMs in Finnish specialized care, which is characterized by long travel distances and a large number of small centers treating patients suffering from ILDs. An electronic questionnaire was sent to ILD experts working at five academic centers of Finland regarding the implementation of ILD MDMs with the focus on utilization of virtual communication.

Inflammatory myositis-associated interstitial lung disease can be distinguished from that associated with other connective tissue diseases.

Background: Acute onset of interstitial lung disease (ILD) has been described in patients with idiopathic inflammatory myositis (IIM), but controlled studies about this issue are sparse. The aim of this study was to compare disease onset, demographics, and high-resolution computed tomography (HRCT) patterns in IIM-ILD and other connective tissue disease (CTD)-ILDs.

Methods: Clinical and radiological data of 22 IIM-ILD and 132 other CTD-ILD patients was retrospectively gathered from hospital registries between January 2000 and November 2019.

National data on prevalence of idiopathic pulmonary fibrosis and antifibrotic drug use in Finnish specialised care.

Introduction: The previous data concerning the prevalence of idiopathic pulmonary fibrosis (IPF) and the frequency of antifibrotic drug use in Finland were based on research registries and medical records whereas nationwide data on the number of patients with IPF in specialised care and those on antifibrotic treatment have not been published.

Methods: We made an information request to the Finnish National Hospital Discharge Register (Hilmo) covering the whole population of Finland to find out the annual numbers of patients with IPF treated in specialised care in 2016-2021. The numbers of the patients initiating and using pirfenidone and nintedanib were requested from the Social Insurance Institution of Finland (Kela) for the same time period.

Reticulation pattern without honeycombing on high-resolution CT is associated with the risk of disease progression in interstitial lung diseases.

Background: The disease course of idiopathic pulmonary fibrosis (IPF) is progressive and occasionally, other types of interstitial lung disease (ILD) may progress similarly to IPF. This study aimed to evaluate risk factors for disease progression within 24 months in patients with various ILDs.

Methods: This prospective study obtained 97 patients with a suspected ILD who underwent a transbronchial lung cryobiopsy.

Risk factors of clinically significant complications in transbronchial lung cryobiopsy: A prospective multi-center study.

Background: The use of a transbronchial lung cryobiopsy (TBLC) is increasing as a diagnostic method of interstitial lung diseases (ILD). This study aimed to evaluate risk factors associated with clinically significant complications of TBLC in ILD patients.

Methods: Patients referred to Kuopio or Tampere university hospitals, in Finland, for a suspected ILD were included.

Decline in Mast Cell Density During Diffuse Alveolar Damage in Idiopathic Pulmonary Fibrosis.

Mast cells (MCs) are known to be involved in the pathogenesis of idiopathic pulmonary fibrosis (IPF), although their role in acute exacerbations of IPF has not been investigated. The aims of the study were to evaluate the numbers of MCs in fibrotic and non-fibrotic areas of lung tissue specimens of idiopathic pulmonary fibrosis (IPF) patients with or without an acute exacerbation of IPF, and to correlate the MC density with clinical parameters. MCs of IPF patients were quantified from surgical lung biopsy (SLB) specimens (n = 47) and lung tissue specimens taken at autopsy (n = 7).

Several specific high-resolution computed tomography patterns correlate with survival in patients with idiopathic pulmonary fibrosis.

Background: Evidence of honeycombing in high-resolution computed tomography (HRCT) is a recognized risk factor for shortened survival in patients with idiopathic pulmonary fibrosis (IPF), but few studies have evaluated the feasibility of exploiting other specific patterns for predicting survival. The aim of this study was to examine the extent of specific HRCT patterns in IPF and determine whether they correlate with clinical features, pulmonary function tests (PFT), and survival.

Methods: Both the presence and extent of specific HRCT patterns, such as traction bronchiectasis, honeycombing, architectural distortion, reticulation, emphysema, and ground glass opacity, in 129 HRCT examinations were scored semi-quantitatively in three zones of each lung.

Causes of acute respiratory hospitalizations predict survival in fibrosing interstitial lung diseases.

Acute exacerbation of ILD (AE-ILD) is a common reason for hospitalization; it is also associated with significant mortality. Less is known about the prognostic significance of other events causing acute, non-elective hospitalizations in ILD patients. ILD patients hospitalized due to acute respiratory worsening were collected from medical records.

Bronchoalveolar lavage differential cell count on prognostic assessment of patients with stable or acute interstitial lung disease: A retrospective real-life study.

BAL cell differential counts of 133 therapy naive ILD patients and 43 patients during acute exacerbation of ILD (AE-ILD) were retrospectively evaluated. In the 20 patients who underwent BAL both at baseline and during an AE-ILD, there was an increase in neutrophils but a decrease in macrophages and eosinophils in the BAL obtained during AE-ILD. A detectable number of basophils at the baseline was a novel risk factor for earlier death and the occurrence of AE-ILD.

Cough-provocation tests with hypertonic aerosols.

Recent advances in cough research suggest a more widespread use of cough-provocation tests to demonstrate the hypersensitivity of the cough reflex arc. Cough-provocation tests with capsaicin or acidic aerosols have been used for decades in scientific studies. Several factors have hindered their use in everyday clinical work: lack of standardisation, the need for special equipment and the limited clinical importance of the response.

Prognosis and causes of death of patients with acute exacerbation of fibrosing interstitial lung diseases.

Background: The aim of this study was to compare the clinical characteristics, causes of death and factors impacting on the prognosis of patients with idiopathic pulmonary fibrosis (IPF) and other fibrosing interstitial lung disease (FILD) with a history of acute exacerbation (AE) of IPF or FILD.

Methods: Retrospective data of hospital treatment periods caused by AE-IPF and AE-FILD were collected from medical records. Clinical features and survival data of IPF and non-IPF cases were evaluated and compared.

Comparison of disease progression subgroups in idiopathic pulmonary fibrosis.

Background: Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial pneumonia with an unpredictable course. The aims of this study were to retrospectively re-evaluate a cohort of patients with IPF according to the 2011 international IPF guidelines and 1) to characterize the subgroups of patients when classified according to their observed survival times and 2) to evaluate whether Composite Physiologic Index (CPI), Gender-Age-Physiology (GAP) Index or clinical variables could predict mortality.

Methods: Retrospective data was collected and patients were classified into subgroups according to their observed lifespans.

Underlying and immediate causes of death in patients with idiopathic pulmonary fibrosis.

Background: The most common cause of death of patients with idiopathic pulmonary fibrosis (IPF) has been reported to be the lung disease itself and mortality from IPF appears to be increasing. However, the causes of death in patients with IPF taking into account differences between genders and smoking histories as well as disease progression, have not been previously explored.

Methods: Retrospective data from hospital register and death certificates from national database of IPF patients treated in Kuopio University Hospital (KUH) from 2002 to 2012 were collected.

Several high-resolution computed tomography findings associate with survival and clinical features in rheumatoid arthritis-associated interstitial lung disease.

Objective: To compare the presence and extent of several high-resolution computed tomography (HRCT) observations in different subtypes of rheumatoid arthritis-related interstitial lung disease (RA-ILD) and to examine associations between radiological findings, hospitalization, age, RA duration, pulmonary function tests (PFT) and survival.

Materials And Methods: HRCTs from 60 RA-ILD patients were independently evaluated and re-categorized into usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP), organizing pneumonia (OP), diffuse alveolar damage (DAD) and unclassified subtypes by two radiologists. The presence and extent, which was reported using a semi-quantitative scoring system, of e.

Long-term prognosis of chronic cough: a prospective, observational cohort study.

Background: The long-term prognosis of chronic cough and its determinants need to be clarified.

Methods: This is a prospective, observational cohort study. Eighty-nine unselected subjects with chronic (> 8 weeks' duration) cough were carefully investigated: Clinical examination, symptom questionnaire, Leicester Cough Questionnaire (LCQ), skin prick tests, ambulatory peak expiratory flow monitoring, spirometry before and after 0.

Effect of smoking and comorbidities on survival in idiopathic pulmonary fibrosis.

Background: Cigarette smoking has been associated with the risk of idiopathic pulmonary fibrosis (IPF). Certain comorbidities have been associated with reduced survival although some studies have indicated that current smokers have a longer survival than ex-smokers. Comorbidities in relation to smoking history have not been previously analyzed.

Are physicians in primary health care able to recognize pulmonary fibrosis?

: The early diagnosis of idiopathic pulmonary fibrosis (IPF) has become increasingly important due to evolving treatment options. IPF patients experience a significant delay in receiving an accurate diagnosis, thus delayed access to tertiary care is associated with higher mortality independently from disease severity. : The aims were to evaluate whether there had been a delay in the referral process, and to determine whether the referring doctors had suspected IPF or other interstitial lung disease (ILD) already during the time of referral.

Are risk predicting models useful for estimating survival of patients with rheumatoid arthritis-associated interstitial lung disease?

Background: Risk predicting models have been applied in idiopathic pulmonary fibrosis (IPF), but still not validated in patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD). The purpose of this study was to test the suitability of three prediction models as well as individual lung function and demographic factors for evaluating the prognosis of RA-ILD patients.

Methods: Clinical and radiological data of 59 RA-ILD patients was re-assessed.

Stepping down from combination asthma therapy: The predictors of outcome.

Background: Stepping down from combination asthma therapy (inhaled corticosteroids (ICS) + long-acting β2 agonists (LABA)) is often avoided due to fear of exacerbations, which may lead to overmedication in well-controlled asthma. A better knowledge about the predictors of outcome might encourage clinicians to start stepping down more often than previously.

Methods: In 55 subjects with well controlled asthma and combination therapy, LABAs were discontinued first, followed by ICS dose halving, and then cessation, in six weeks' intervals.

Variable course of disease of rheumatoid arthritis-associated usual interstitial pneumonia compared to other subtypes.

Background: In rheumatoid arthritis-associated interstitial lung disease (RA-ILD), occurring in 10 % of patients with patients with RA, usual interstitial pattern (UIP) has shown to associate with poor prognosis but more detailed data about the course of the disease in different subtypes is limited. Our aim was to compare the disease course of patients with RA-ILD categorized into either UIP or other types of ILDs.

Methods: Clinical and radiological information of 59 patients with RA-ILD were re-assessed and re-classified into UIP or non-UIP groups, followed by a between-group comparison of demographic data, lung function, survival, cause of death and comorbidities.

[Chronic cough: common problem, discontended patients].

The prevalence of chronic cough is 10 to 15%. It has a strong negative impact on the patients' quality of life and it often causes depression. Many patients find medications unhelpful.

[Irritant-induced asthma].

Irritant-induced asthma is a rare disease, usually being caused by an accidental or other exceptionally strong exposure to substances irritating the respiratory passages. High-dose inhaled corticosteroid medication is immediately started at the emergency call service. If severe exposure is suspected, it is important to monitor the patient at least for a couple of days in hospital.

[Work aggravated asthma].

One out of five working persons with asthma has work-related respiratory symptoms. When exploring the symptoms of a working-age patient it is essential to survey the job description and working conditions. Early intervention in the factors aggravating the respiratory symptoms will decrease morbidity, maintain working capacity and improve the quality of life.
