Background: Not all the patients with sarcoidosis need pharmacological therapy, and the decision to start therapy is based mainly on clinical conditions. The aim of this study was to evaluate the prognostic value of the leukocyte and lymphocyte subpopulations in the bronchoalveolar lavage fluid from these patients.
Methods: Thirty-three nonsmoking patients with sarcoidosis were included and classified based on the presence of Löfgren's syndrome (n = 11), the radiological stage (12 at Stage I, 17 at Stage II, and 4 at Stage III), and their follow-up. Differential leukocyte subsets and the lymphocyte subpopulations were determined by flow cytometry.
Results: The percentage of neutrophils was lower in patients with Löfgren's syndrome (P = 0.038) and in patients at Stage I (P = 0.002). Patients with a poor outcome had a higher percentage of neutrophils (P = 0.004) and NK cells (P = 0.023) than those with a stable disease. Finally, a higher percentage of NK cells was found in those patients who needed a steroid treatment (P = 0.012).
Conclusions: Increased percentages of neutrophils and NK cells in the bronchoalveolar lavage fluid from patients with sarcoidosis are associated with a poor outcome and a higher probability to need steroids treatment. The percentage of neutrophils was also lower in patients with Löfgren's syndrome.

Background And Aim: NK cells and NK-cell-derived cytokines were shown to regulate neutrophil activation in acute lung injury (ALI). However, the extent to which ALI regulates lung tissue-resident NK (trNK) activity and their molecular phenotypic alterations are not well defined. We aimed to assess the impact of 1,25-hydroxy-vitamin-D3 [1,125(OH)D] on ALI clinical outcome in a mouse model and effects on lung trNK cell activations.

Current treatments for chronic obstructive pulmonary disease (COPD), a common respiratory condition, include oxygen therapy and steroids for temporary relief. In this study, we established a rat model of cigarette smoke (CS)-induced COPD and investigated the benefits of a hydrogen-oxygen generator in this model. CS-exposed rats were treated using either a hydrogen-oxygen generator or a steroid.

Background: Reports of autoimmune diseases coexisting with autoimmune pulmonary alveolar proteinosis (autoimmune PAP; APAP) are extremely rare. APAP coexisting with autoimmune diseases may often be misdiagnosed as connective tissue disease-associated interstitial lung disease (ILD). Here, we describe a rare case of a patient with systemic sclerosis who was diagnosed with APAP after the exacerbation of lung opacities during treatment with immunosuppressive agents.

Mycoplasma pneumoniae caused lower respiratory tract infection in children and can exacerbate these infections through the production of various inflammatory factors, with chemokines playing a key role. However, the pathogenesis of this infection is complicated and thus has not been thoroughly studied. We clarified that cytokine expression levels were analyzed in both peripheral blood and bronchoalveolar lavage fluid (BALF), and in vitro assays were conducted using THP-1 macrophages.

A 45-year-old male patient presented with a persistent cough lasting four months, accompanied by fever and significant weight loss. A chest computed tomography revealed cryptogenic pneumonia, and subsequent investigations identified a positive cytomegalovirus (CMV) viral load in bronchoalveolar lavage. A transbronchial biopsy confirmed intranuclear basophilic inclusions indicative of CMV infection.
