Primary immunodeficiency disorders (PIDs) are caused by 1 or more defects of the immune system. Patients are more likely to experience recurrent and/or severe infections and tend to develop a wide range of complications. Respiratory diseases are the main and initial manifestation in most cases and the most common complication. Pulmonary complications cause significant morbidity and mortality in patients with PIDs. Early diagnosis and appropriate treatment can prevent or at least slow the development of respiratory complications...

BACKGROUND: Most patients with restriction have a PFT pattern in which TLC, FVC and FEV1 are reduced to a similar degree. We call this pattern 'simple' restriction (SR). In contrast, we commonly observe a pattern in which FVC percent predicted (pp) is disproportionately reduced relative to TLCpp. We term this pattern 'complex restriction' (CR) and attempted to characterize its clinical, radiologic and physiologic features. METHODS: We reviewed PFTs of patients tested between November 2009 and June 2013 who had restriction (TLC<LLN)...

OBJECTIVES: Systemic sclerosis (SSc) is an autoimmune disease, characterized by fibrosis of the skin and other organs, vascular impairment and deficient immune responses. Mucosal associated invariant T cells (MAIT) cells have been involved in various inflammatory and autoimmune diseases. The aim of this study was to determine the frequencies of MAIT cells in the blood of patients with systemic sclerosis (SSc), and to compare their distribution in the different types of SSc. PATIENTS AND METHODS: Blood samples from SSc patients and healthy controls were examined by flow cytometer to analyze the frequencies of MAIT and γδ T cells...

BACKGROUND: Adult onset Still disease (AOSD) is a rare condition characterized by elevated fever along with arthritic symptoms, elevated polymorphonuclear neutrophil count, evanescent rash, and hyperferritinemia. Diagnosis can be made only after have ruled out more frequent conditions, and Yamagouchi or Fautrel criteria should be applied. Parenchimal lung involvement (PLI) is present in less than 5% of AOSD cases and ranges from aspecific reticular interstitial opacities to life threatening conditions, such as acute respiratory distress syndrome (ARDS)...

The finding of collections of macrophages/histiocytes in lung biopsy and bronchoalveolar lavage is relatively common in routine practice. This morphological feature in itself is pathological, but the exact clinical significance and underlying disease should be evaluated together with clinical data, functional respiratory and laboratory tests and imaging studies.Morphological characteristics of macrophages and their distribution along the different pulmonary structures should be examined carefully by pathologists...

BACKGROUND: Interstitial lung disease (ILD) can be a severe extra-articular disease manifestation in Rheumatoid Arthritis (RA). A potential role of fibrocytes in RA associated ILD (RA-ILD) has not previously been described. We present a modified faster method for measuring circulating fibrocytes, without intracellular staining. The results are compared to the traditional culture method, where the number of monocytes that differentiate into mature fibrocytes in vitro are counted. The results are following compared to disease activity in patients with severe asthma, ILD, RA (without diagnosed ILD) and RA with verified ILD (RA-ILD)...

OBJECTIVE: Diabetes mellitus, smoking, dyslipidemia, and obesity play an important role in the etiology of erectile dysfunction, particularly in cases with vascular insufficiency. These risk factors also target the lungs due to their systemic effects. MATERIALS AND METHODS: Patients with penile vascular insufficiency determined at Doppler ultrasonography and undergoing thoracic computerized tomography for various reasons were included in this study. A history of acute thoracic trauma, pneumonic consolidation, or pelvic surgery and trauma were regarded as exclusion criteria...

Lung fibrosis (LF) is a chronic and progressive lung disease characterized by pulmonary parenchyma progressive lesion, inflammatory infiltration, and interstitial fibrosis. It is developed by excessive collagen deposition and other cellular matrix components, resulting in severe changes in the alveolar architecture. Considering the absence of effective treatment, the aim of this study was to investigate the effect of photobiomodulation therapy (PBMT) on the development of PF. For this purpose, we used C57BL6 mice subjected to induction of LF by bleomycin administration (1...

BACKGROUND: Lung transplants have produced very favorable outcomes for patients with interstitial lung disease (ILD) in Japan. However, because of the severe donor lung shortage, patients must wait approximately 2.5 years before they can undergo transplantation and many candidates die before allocation. We reveal the clinical characteristics of Japanese patients with ILD who are candidates for lung transplants and the risk factors for early death while on the waiting list. METHODS: We retrospectively reviewed the clinical data of patients registered in the Japan Organ Transplant Network from Okayama University Hospital who are candidates for cadaveric lung transplants for ILD between 1999 and 2015...

So-My Koo, Soo-Taek Uh
Interstitial lung disease (ILD) occurs in 15% of patients with collagen vascular disease (CVD), referred to as connective tissue disease (CTD). Despite advances in management strategies, ILD continues to be a significant cause of mortality in patients with CVD-associated ILD (CTD-ILD). There is a lack of randomized, clinical trials assessing pharmacological agents for CTD-ILD, except in cases of ILD-associated systemic sclerosis (SSc). This may be due to the lack of CTD cases available, the difficulty of histological confirmation of ILD, and the various types of CTD and ILD...

BACKGROUND AND OBJECTIVE: To determine whether computer-based quantification (CALIPER software) is superior to visual computed tomography (CT) scoring in the identification of CT patterns indicative of restrictive and obstructive functional indices in hypersensitivity pneumonitis (HP). METHODS: A total of 135 consecutive HP patients had CT parenchymal patterns evaluated quantitatively by both visual scoring and CALIPER. Results were evaluated against: forced vital capacity (FVC), total lung capacity (TLC), diffusing capacity for carbon monoxide (DLCO ) and a composite physiological index (CPI) to identify which CT scoring method better correlated with functional indices...

Extrahepatic manifestations of hepatitis C virus (HCV) infection are a rare but serious condition. This article summarizes the current literature on the association between HCV and endocrine and pulmonary manifestations, as well as idiopathic thrombocytopenic purpura (ITP). HCV may directly infect extrahepatic tissues and interact with the immune system predisposing for obstructive and interstitial lung disease, ITP, autoimmune thyroiditis, infertility, growth hormone and adrenal deficiencies, osteoporosis, and potentially lung and thyroid cancers...

Pulmonary Langerhans cell histiocytosis (PLCH) is a diffuse lung disease that usually affects young adult smokers. PLCH affects different lung compartments; bronchiolar, interstitial and pulmonary vascular dysfunction may coexist to varying extents, resulting in diverse phenotypes. Analyses of PLCH tissues have identified activating mutations of specific mitogen-activated protein kinases (BRAF(V600E) and others). The current consensus is that PLCH represents a myeloid neoplasm with inflammatory properties: the myeloid tumour cells exhibit surface CD1a expression and up to 50% of the cells harbour activating BRAF or other MAPK mutations...

Pulmonary fibrosis (PF) is a lethal, chronic and progressive respiratory disease leading to interstitial lung damage and serious breathing problems. The pathogenic mechanism involves activation, migration, proliferation and differentiation of fibroblasts into myofibroblats inducing extracellular matrix accumulation that destroy lung parenchyma. Available antifibrotic treatment options are limited to Pirfenidone and Nintedanib that prevent deterioration without an improvement of this disease. The use of plant extracts and natural bioactive compounds for the treatment of PF has been known for more than thirty years in China...

Pulmonary hypertension (PH) complicating chronic obstructive pulmonary disease (COPD-PH) and interstitial lung disease (ILD-PH) (World Health Organization [WHO] Group III PH) increases medical costs and reduces survival. Despite limited data, many clinicians are using pulmonary arterial hypertension (PAH)-specific therapy to treat WHO Group III PH patients. To further investigate the utility of PAH-specific therapy in WHO Group III PH, we performed a systematic review and meta-analysis. Relevant studies from January 2000 through May 2016 were identified in the MEDLINE, EMBASE, and COCHRANE electronic databases and www...
