[PMID: 38384315 PMCID: PMC10881243 DOI: 10.1155/2024/6665568] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 01/03/2024] [Accepted: 02/05/2024] [Indexed: 02/23/2024] Open
Abstract
Objectives The purpose of this study was to retrospectively assess cystic changes in findings on follow-up CT scans of patients with fibrotic nonspecific interstitial pneumonia (NSIP). Methods The initial and last high-resolution CT scans of 58 patients with pathologically proven fibrotic NSIP were evaluated retrospectively. The median follow-up periods were 48 months (range, 12-183 months). The pattern, extent, and distribution of abnormal CT findings were compared with findings in the same region on previous and subsequent CT scans with a focus on cystic lesions. Results Cystic lesions in a cluster were shown in 16 patients (28%) with fibrotic NSIP on the last CT scans. Focal clustered cysts were found in 5 cases and diffuse clustered cysts were seen in 11 cases. Focal clustered cysts mimicked honeycombing seen in usual interstitial pneumonia (UIP). Diffuse cysts were uniform in size in 7 of the 11 cases. Traction bronchiectasis in a cluster was seen in 3 of the 7 cases. The clustered cystic changes on CT during the course of NSIP mainly consisted of traction bronchiectasis and bronchiolectasis. Conclusions Long-standing NSIP did not form honeycombing. The clustered cysts in patients with fibrotic NSIP were mainly remodeling of bronchiectasis.

Abstract
The recommendations were developed as answers to previously formulated questions concerning everyday diagnostic and therapeutic challenges. They were developed based on a review of the current literature using the GRADE methodology. The experts suggest that PF-ILD be diagnosed based on a combination of different criteria, such as the aggravation of symptoms, progression of radiological lesions, and worsening of lung function test parameters. The experts recommend a precise diagnosis of an underlying disease, with serological testing for an autoimmune disease always being included. The final diagnosis should be worked out by a multidisciplinary team (MDT). Patients with an interstitial lung disease other than IPF who do not meet the criteria for the progressive fibrosis phenotype should be monitored for progression, and those with systemic autoimmune diseases should be regularly monitored for signs of interstitial lung disease. In managing patients with interstitial lung disease associated with autoimmune diseases, an opinion of an MDT should be considered. Nintedanib rather than pirfenidon should be introduced in the event of the ineffectiveness of the therapy recommended for the treatment of the underlying disease, but in some instances, it is possible to start antifibrotic treatment without earlier immunomodulatory therapy. It is also admissible to use immunomodulatory and antifibrotic drugs simultaneously. No recommendations were made for or against termination of anti-fibrotic therapy in the case of noted progression during treatment of a PF-ILD other than IPF. The experts recommend that the same principles of non-pharmacological and palliative treatment and eligibility for lung transplantation should be applied to patients with an interstitial lung disease other than IPF with progressive fibrosis as in patients with IPF.

Abstract
PURPOSE This article is an in-depth review of the complex classification, diagnosis, and treatment of idiopathic interstitial pneumonias (IIP), as well as emergence of new treatment options. SUMMARY Idiopathic interstitial pneumonias consist of various subgroup classifications that require expert analysis of imaging and histology to accurately diagnose this broad group of patients. Timely and accurate assessment of these patients is key in developing an appropriate pharmacological plan. The pathophysiology of IIP is not well understood but has been linked to an immune response resulting in inflammation, fibrosis, or proliferation of lung tissue which reduces lung function. Lung transplantation is currently the only curative option for treatment, but many new antiproliferative and immunosuppressive agents are being used to effectively slow the progression of lung dysfunction. CONCLUSION An often mixed radiological and histological pattern along with the invasive nature of biopsy for gold standard diagnosis create a challenge for the accurate identification of IIP. Further understanding of these idiopathic interstitial pneumonias will pave the way forward to the emergence of new treatment options and updates to standards of care.

Abstract
BACKGROUND The choice of immunosuppressive therapy in interstitial lung disease (ILD) other than idiopathic pulmonary fibrosis (IPF) is based on safety profile and expected efficacy. Azathioprine is one of the most commonly used agents to treat ILD. The immunosuppressive effect and pancreatitis risk of azathioprine are influenced by the activity of the enzyme thiopurine methyltransferase (TPMT) and by the genetic mutations in HLA-DQA1-HLA-DRB locus, respectively. We hypothesized that systematic genotyping prior to starting azathioprine improves the rate of discontinuation of immunosuppressive therapy and the total incidence of adverse drug reactions (ADRs). METHODS Eighty-two patients with ILD other than IPF were included in the study. The rate of immunosuppressive therapy discontinuation due to major ADRs and the total incidence of ADRs were compared between a cohort of genotyped patients (n = 49) and an untested cohort of patients (n = 33). RESULTS Thirty-seven out of 49 patients in the genotyped cohort and 27 out of 33 patients in the untested cohort were started on azathioprine. The rate of immunosuppressive therapy discontinuation due to major ADRs was significantly lower (6/49) in the genotyped cohort compared to the untested cohort (11/33; p = 0.0276). All but one discontinuation due to severe ADRs occurred within a month of therapy. However, the total incidence rate of ADRs was very similar in the 2 cohorts (0.025 in the genotyped cohort vs. 0.023 in the untested cohort). CONCLUSION In patients with ILD other than IPF, genotyping for azathioprine metabolism prior to starting therapy is associated with a significantly reduced rate of immunosuppressive therapy discontinuation due to major ADRs, with prevention of bone marrow suppression and pancreatitis, but without a reduction of the total incidence of ADRs. While these data support the use of genetic profiling prior to starting azathioprine to treat ILD, its cost effectiveness remains to be established.

Abstract
The etiopathogenesis of systemic sclerosis (SSc)-associated interstitial lung disease (ILD) is still debated and no therapeutic options have proved fully effective to date. The intracellular Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway is highly conserved among either immune or nonimmune cells and involved in inflammation and fibrosis. Evidence from preclinical studies shows that the JAK/STAT signaling cascade has a crucial role in the differentiation of autoreactive cells as well as in the extracellular matrix remodeling that occurs in SSc. Therefore, it is likely that the use of oral small molecule JAK-inhibitors, especially if prescribed early, may prevent or slow the progression of SSc-associated ILD, but few clinical studies currently support this hypothesis.

Abstract
Acute interstitial pneumonia (AIP) is a rare and severe form of idiopathic interstitial lung disease. Treatment is primarily supportive with supplemental oxygenation and mechanical ventilation. Prognosis is poor, but long-term survival is possible after recovery from AIP. We present a case of a 48-years-old previously healthy female who was admitted due to acute shortness of breath and respiratory failure which started three days after she ran a half-marathon. After excluding infectious causes and connective-tissue diseases, a presumptive diagnosis of AIP was made based on clinical and radiological characteristics. The patient was successfully treated with high-dose corticosteroids and mycophenolate mofetil.

Abstract
The aim of the study was to investigate the effects of tetrandrine combined with acetylcysteine on exercise tolerance, pulmonary function, transforming growth factor-β1 (TGF-β1) and matrix metalloproteinase 7 (MMP-7) in silicosis patients. A retrospective analysis was performed on 149 silicosis patients admitted to the Maternal and Child Health Care Hospital of Zhangqiu District between August, 2015 and September, 2017. Of the 149 patients, 70 patients treated with acetylcysteine comprised the control group, and 79 treated with tetrandrine combined with acetylcysteine constituted the study group. The concentrations of serum TGF-β1 and MMP-7 before and after treatment were detected by enzyme-linked immunosorbent assay (ELISA), and the exercise tolerance and pulmonary function were compared. Chest distress, chest pain, cough, expectoration and dyspnea in the two groups were relieved after treatment, and the improvement rates of chest distress, chest pain and dyspnea in the study group were significantly higher than those in the control group (P<0.05). Before treatment, there was no significant difference in the results of the 6-minute walk test (6MWT) between the two groups (P>0.05). After treatment, the 6MWT in the two groups was significantly increased (P<0.05), and the improvement effect in the study group was more marked than that in the control group (P<0.05). There was no significant difference in the pulmonary function indexes between the two groups before treatment (P>0.05). Before treatment, there was no significant difference in serum TGF-β1 and MMP-7 expression levels between the two groups (P>0.05). By contrast, after treatment, the levels in the two groups were significantly decreased, with the levels in the study group being significantly lower than that the control group (P<0.05). In conclusion, tetrandrine combined with acetylcysteine can improve pulmonary function and exercise tolerance of patients with silicosis by inhibiting the expressions of TGF-β1 and MMP-7, thus improving clinical efficacy.
