AIM:To examine the disparities in macular retinal vascular density between individuals with connective tissue disease-related interstitial lung disease(CTD-ILD)and healthy controls(HCs)by optical coherence tomography angiography(OCTA)and to investigate the changes in microvascular density in abnormal eyes.METHODS:For a retrospective case-control study,a total of 16 patients(32 eyes)diagnosed with CTD-ILD were selected as the ILD group.The 16 healthy volunteers with 32 eyes,matched in terms of age and sex with the patients,were recruited as control group.The macular retina’s superficial retinal layer(SRL)and deep retinal layer(DRL)were examined and scanned using OCTA in each individual eye.The densities of retinal microvascular(MIR),macrovascular(MAR),and total microvascular(TMI)were calculated and compared.Changes in retinal vascular density in the macular region were analyzed using three different segmentation methods:central annuli segmentation method(C1-C6),hemispheric segmentation method[uperior right(SR),superior left(SL),inferior left(IL),and inferior right(IR)],and Early Treatment Diabetic Retinopathy Study(ETDRS)methods[superior(S),inferior(I),left(L),and right(R)].The data were analyzed using Version 9.0 of GraphPad prism and Pearson analysis.RESULTS:The OCTA data demonstrated a statistically significant difference(P<0.05)in macular retinal microvessel density between the two groups.Specifically,in the SRL and DRL analyses,the ILD group exhibited significantly lower surface density of MIR and TMI compared to the HCs group(P<0.05).Furthermore,using the hemispheric segmentation method,the ILD group showed notable reductions in SL,SR,and IL in the superficial retina(P<0.05),as well as marked decreases in SL and IR in the deep retina(P<0.05).Similarly,when employing the ETDRS method,the ILD group displayed substantial drops in superficial retinal S and I(P<0.05),along with notable reductions in deep retinal L,I,and R(P<0.05).In the central annuli segmentation method,the ILD group exhibited a significant decrease in the superficial retinal C2-4 region(P<0.05),whereas the deep retina showed a notable reduction in the C3-5 region(P<0.05).Additionally,there was an observed higher positive likelihood ratio in the superficial SR region and deep MIR.Furthermore,there was a negative correlation between conjunctival vascular density and both deep and superficial retinal TMI(P<0.001).CONCLUSION:Patients with CTD-ILD exhibits a significantly higher conjunctival vascular density compared to the HCs group.Conversely,their fundus retinal microvascular density is significantly lower.Furthermore,CTD-ILD patients display notably lower superficial and deep retinal vascular density in comparison to the HCs group.The inverse correlation between conjunctival vascular density and both superficial and deep retinal TMI suggests that detecting subtle changes in ocular microcirculation could potentially serve as an early diagnostic indicator for connective tissue diseases,thereby enhancing disease management. 展开更多

BACKGROUND This study presents a case of rapidly developing respiratory failure due to antisynthetase syndrome(AS)following coronavirus disease 2019(COVID-19)in a 33-year-old man diagnosed with Klinefelter syndrome(KS).CASE SUMMARY A 33-year-old man with a diagnosis of KS was admitted to the Department of Pulmonary and Critical Care Medicine of a tertiary hospital in China for fever and shortness of breath 2 wk after the onset of COVID-19.Computed tomography of both lungs revealed diffuse multiple patchy heightened shadows in both lungs,accompanied by signs of partial bronchial inflation.Metagenomic next-generation sequencing of the bronchoalveolar lavage fluid suggested absence of pathogen.A biopsy specimen revealed organizing pneumonia with alveolar septal thickening.Additionally,extensive auto-antibody tests showed strong positivity for anti-SSA,anti-SSB,anti-Jo-1,and anti-Ro-52.Following multidisciplinary discussions,the patient received a final diagnosis of AS,leading to rapidly progressing respiratory failure.CONCLUSION This study underscores the clinical progression of AS-associated interstitial lung disease subsequent to viral infections such as COVID-19 in patients diagnosed with KS. 展开更多

Amyloidosis is a rare spectrum of disease which involves deposition of misfolded extracellular proteins (amyloids) in various body organs leading to progressive organ dysfunction. Clinical presentation can be variable depending on the organ involved and type of protein. Amyloidosis can be classified based on quantity, type, and location of these proteins. Amyloid light-chain amyloidosis develops in the bone marrow, producing abnormal forms of light-chain proteins, which cannot be broken down. These proteins transform into amyloid fibrils and form amyloid deposits in different organs. Pulmonary amyloidosis is uncommonly diagnosed since it is rarely symptomatic. Diagnosis of pulmonary amyloidosis is usually made in the setting of systemic amyloidosis;however, it may present as localised pulmonary disease. Localized pulmonary Amyloidosis can present as nodular, cystic, or tracheobronchial amyloidosis. Depending on the degree of the interstitial involvement, it may affect alveolar gas exchange and cause respiratory symptoms. This is a case of a 47-year-old female with background history of interstitial lung disease presenting with progressive shortness of breath. Computed tomography scan revealed bilateral pulmonary nodules. The patient was referred to our thoracic surgery team with the suspicion of bronchogenic malignancy with metastasis. Diagnostic video assisted wedge resection was performed for this patient, and histology confirmed pulmonary amyloidosis of nodular type. Amyloid deposition simulates both inflammatory and neoplastic conditions. Definitive diagnosis requires biopsy confirmation therefore early detection and commencing the patient on appropriate treatment pathway may help in symptomatic relief and better outcome. 展开更多

Objective:To explore the association between the Lung Immune Prognostic Index(LIPI)and 1-year all-cause mortality in patients with idiopathic inflammatory myopathy related interstitial lung disease(IIM-ILD).Methods:Patients who were diagnosed with IIM-ILD at West China Hospital,Sichuan University from January 2008 to December 2021 were retrospectively included and categorized into three groups based on LIPI.Univariable and multivariable Cox proportional hazards models were conducted to explore potential association between the LIPI and patients'mortality.Results:A total of 1116 patients were screened,and 830 were included in this study.The multivariable Cox analysis showed that,compared with patients with poor LIPI,the hazard ratio(HR)for all-cause 1-year mortality was 0.22(95%CI 0.05-0.93,P=0.04)for patients in the good LIPI group(LDH<250 IU/L and dNLR<3).After excluding patients lost to follow-up within one year,a similar result was found for LIPI(HR 0.20,95%CI 0.05-0.86;P=0.03).Conclusions:Good LIPI was independently associated with decreased risk of all-cause 1-year mortality in patients with IIM-ILD.This easy-to-obtain index might be served as a potential marker for assessing the prognosis of IIM-ILD. 展开更多

BACKGROUND Lung damage in systemic juvenile arthritis(sJIA)is one of the contemporary topics in pediatric rheumatology.Several previous studies showed the severe course and fatal outcomes in some patients.The information about interstitial lung disease(ILD)in the sJIA is scarce and limited to a total of 100 cases.AIM To describe the features of sJIA patients with ILD in detail.METHODS In the present retrospective cohort study,information about 5 patients less than 18-years-old with sJIA and ILD were included.The diagnosis of sJIA was made according to the current 2004 and new provisional International League of Associations for Rheumatology criteria 2019.ILD was diagnosed with chest computed tomography with the exclusion of other possible reasons for concurrent lung involvement.Macrophage activation syndrome(MAS)was diagnosed with HLH-2004 and 2016 EULAR/ACR/PRINTO Classification Criteria and hScores were calculated during the lung involvement.RESULTS The onset age of sJIA ranged from 1 year to 10 years.The time interval before ILD ranged from 1 mo to 3 years.The disease course was characterized by the prevalence of the systemic features above articular involvement,intensive rash(100%),persistent and very active MAS(hScore range:194-220)with transaminitis(100%),and respiratory symptoms(100%).Only 3 patients(60%)developed a clubbing phenomenon.All patients(100%)had pleural effusion and 4 patients(80%)had pericardial effusion at the disease onset.Two patients(40%)developed pulmonary arterial hypertension.Infusion-related reactions to tocilizumab were observed in 3(60%)of the patients.One patient with trisomy 21 had a fatal disease course.Half of the remaining patients had sJIA remission and 2 patients had improvement.Lung disease improved in 3 patients(75%),but 1 of them had initial deterioration of lung involvement.One patient who has not achieved the sJIA remission had the progressed course of ILD.No cases of hyper-eosinophilia were noted.Four patients(80%)received canakinumab and one(20%)tocilizumab at the last follow-up visit.CONCLUSION ILD is a severe life-threatening complication of sJIA that may affect children of different ages with different time intervals since the disease onset.Extensive rash,serositis(especially pleuritis),full-blown MAS with transaminitis,lymphopenia,trisomy 21,eosinophilia,and biologic infusion reaction are the main predictors of ILD.The following studies are needed to find the predictors,pathogenesis,and treatment options,for preventing and treating the ILD in sJIA patients. 展开更多

Diabetes mellitus (DM) is a chronic metabolic disease and its prevalence has beensteadily increasing all over the world. DM and its associated micro andmacrovascular complications result in significant morbidity and mortality. Themicrovascular complications are usually manifested as retinopathy, neuropathy,nephropathy and macrovascular complications generally affect the cardiovascularsystem. In addition to these complications, DM also affects the lungs because of itsrich vascularity and abundance in connective tissue (collagen and elastin). DMhas been found to cause microvascular complications and proliferation ofextracellular connective tissue in the lungs, leading to decline in lung function in arestrictive pattern. Interstitial lung disease (ILD) includes a diverse group ofdisease conditions characterized by different degrees of inflammation and fibrosisin the pulmonary parenchyma. Idiopathic pulmonary fibrosis (IPF) is one of thecommon type of idiopathic interstitial pneumonia with a high mortality rate. IPFis characterized by chronic progressive fibrosis leading to progressive respiratoryfailure. In this review we focus on lung as the target organ in DM and theassociation of DM and ILD with special emphasis on IPF. 展开更多

Interstitial lung and liver disease(ILLD) is caused by biallelic mutations in the methionyl-tRNA synthetase(MARS) gene. To date, no genetic changes other than missense variants were reported in the literature. Here, we report a five-month old female infant with typical ILLD(failure to thrive, developmental delay, jaundice, diffuse interstitial lung disease, hepatomegaly with severe steatosis, anemia, and thrombocytosis) showing novel phenotypes such as kidney stones, acetabular dysplasia, prolonged fever, and extreme leukocytosis. Whole exome sequencing revealed a novel truncating variant(c.2158 C>T/p.Gln720 Stop) together with a novel tri-nucleotide insertion(c.893_894 insTCG that caused the insertion of an arginine at amino acid position 299) in the MARS gene. 展开更多

Pulmonary abnormalities are not frequently encountered in patients with inflammatory bowel diseases.However,lung toxicity can be induced by conventional medications used to maintain remission,and similar evidence is also emerging for biologics.We present the case of a young woman affected by colonic Crohn’s disease who was treated with oral mesalamine and became steroid-dependent and refractory to azathioprine and adalimumab.She was referred to our clinic with a severe relapse and was treated with infliximab,an antitumor necrosis factor α(TNF-α)antibody,to induce remission.After an initial benefit,with decreases in bowel movements,rectal bleeding and C-reactive protein levels,she experienced shortness of breath after the 5thinfusion.Noninfectious interstitial lung disease was diagnosed.Both mesalamine and infliximab were discontinued,and steroids were introduced with slow but progressive improvement of symptoms,radiology and functional tests.This represents a rare case of interstitial lung disease associated with infliximab therapy and the effect of drug withdrawal on these lung alterations.Given the increasing use of anti-TNF-α therapies and the increasing reports of pulmonary abnormalities in patients with inflammatory bowel diseases,this case underlines the importance of a careful evaluation of respiratory symptoms in patients undergoing infliximab therapy. 展开更多

Patients with interstitial lung disease commonly exhibit abnormal sleep architecture and increased sleep fragmentation on polysomnography. Fatigue is a frequent complaint, and it is likely that poor sleep quality is a significant contributor. A number of studies have shown that sleep disordered breathing is prevalent in this population, particularly in the idiopathic pulmonary fibrosis subgroup. The factors that predispose these patients to obstructive sleep apnoea are not well understood, however it is believed that reduced caudal traction on the upper airway can enhance collapsibility. Ventilatory control system instability may also be an important factor, particularly in those with increased chemo-responsiveness, and in hypoxic conditions. Transient, repetitive nocturnal oxygen desaturation is frequently observed in interstitial lung disease, both with and without associated obstructive apnoeas.

A 66-year-old Japanese man with pancreatic cancer received eleven courses of gemcitabine monotherapy.The tumor responded to gemcitabine until metastatic liver tumors progressed.Subsequently,he was treated with S-1,an oral fluoropyrimidine anticancer agent,as salvage chemotherapy.Forty-two days after initiating S-1,he presented with dyspnea and fever.Chest computed tomography showed diffuse interstitial lesions with thickening of the alveolar septa and ground glass opacity.Serum KL-6 level was elevated to 1,230 U/mL and he did not use any other drugs except insulin.Thus,the development of interstitial lung disease(ILD)was considered to be due to S-1.Arterial blood oxygen pressure was 49.6 Torr in spite of oxygen administration(5 L/min).Steroid therapy improved his symptoms and the interstitial shadows on chest radiograph.Although S-1-induced ILD has mostly been reported to be mild,clinicians should be aware that S-1 has the potential to cause fatal ILD. 展开更多

Acute exacerbations of idiopathic pulmonary fibrosis(IPF) is a severe respiratory condition with high mortality rate. Direct hemoperfusion with polymyxin B-immobilized fiber columns(PMX-DHP) was originally introduced for the treatment of septic shock. Application of PMX-DHP to the treatment of acute exacerbations of IPF may improve oxygenation and survival of the patients with the disease. In addition to acute exacerbations of IPF, PMXDHP has been applied to acute respiratory failure fromvarious causes; an amyopathic dermatomyositis patient who developed rapidly progressive interstitial lung disease(ILD) with elevated anti-CADM-140/MDA5 autoantibody and a patient with severe amiodarone pulmonary toxicity. It is also demonstrated that PMX-DHP performed on the first day of steroid pulse therapy may improve the prognosis of patients with rapidly progressive ILDs in a case-control setting. PMX treatment decreases not only various circulating molecules but also inflammatory cells, in particular activated monocytes, producing such mediators. Although the incidence of acute exacerbations of IPF is too low for proper randomization, in order to test the effects of PMX-DHP on the disease, a cohort or casecontrol analytic study needs to be conducted, preferably from more than one center or research group. 展开更多

Objective: To explore the correlations between miR-125b, miR-200c, and the severity of interstitial lung disease associated with dermatomyositis/polymyositis (DM/PM-ILD). Methods: 30 consecutive patients with DM/PM and 23 healthy controls were recruited into current study. Anti-JO-1, anti-SSA, muscle enzymes, the data of chest HRCT and pulmonary function test were collected. 9 consecutive DM/PM-ILD patients underwent bronchoalveolar lavage (BAL). TGF-β1 and surfactant protein D (SP-D) in BAL fluid (BALF) and plasma were detected by ELISA. miR-125b and miR-200c in PBMCs and bronchoalveolar cells were detected by QRT-PCR. All patients were classified into three groups: Mild or non-ILD group, moderate ILD group, and severe ILD group. The correlations between miRNAs and the severity of ILD, the lung damage markers, auto-antibodies, were analyzed. Results: The levels of miR-125b and miR-200c in bronchoalveolar cells were higher than in PBMCs, and the levels of TGF-β1 and SP-D were higher in BALF than in plasma in DM/PM-ILD patients. There were positive correlations between miR-125b, miR-200c in bronchoalveolar cells and SP-D in BALF. The levels of miR-125b and miR-200c in severe ILD group were higher than in mild or non-ILD and moderate ILD groups. There were negative correlations between miR-125b, miR-200c, and FEV1, and between miR-200c and DLCO. The patients with anti-JO-1 antibody had higher levels of miR-125b and miR-200c, and had more severe condition of ILD. Conclusion: miR-125b and miR-200c were positively correlated with the lung damage and severity of ILD in DM/PM, which could be important markers for judgement of disease condition in clinic. 展开更多

Objective:This paper aims to determine the reliability and validity of the Chinese version of a tool that assesses the quality of life in idiopathic pulmonary fibrosis(cATAQ-IPF)in patients with interstitial lung disease(ILD).Methods:We used the process of scale introduction to establish cATAQ-IPF.The content validity of the scale was evaluated by six experts.A total of 92 patients with ILD completed the cATAQ-IPF,St.George's respiratory questionnaire(SGRQ),and The Medical Research Council dyspnoea scale at the baseline,and 15 patients completed cATAQ-IPF at the follow-up period 2 weeks later.Thus,yielding data were used to assess various psychometric properties of cATAQ-IPE Intraclass correlation coefficient(ICC),Cronbach'sαcoefficient,content validity index(CVI),item-level CVI(I-CVI),Pearson's coefficients,criterion-relation validity,and known-group validity were used for data analysis.Results:The cATAQ-IPF showed excellent test-retest reliability(ICC=0.95),except for the therapy domain(Cronbach'sα=0.60)and acceptable internal consistency(Cronbach'sα=0.96 for the total).The scale-level CVI was 0.80,and the I-CVI was in the range of 0.78-1.00.The total cATAQ-IPF score was strongly correlated with the SGRQ total score(r=0.71,P<0.01).The cATAQ-IPF score of patients with ILD was 250.74±47.39,and that of patients with IPF was 287.90±22.56.Patients with IPF possessed considerable impairments in health-related quality of life according to the cATAQ-IPF score(t=4.94,P<0.01).Conclusions:The cATAQ-IPF is a reliable and valid instrument for the evaluation of quality of life of Chinese patients with various forms of ILD. 展开更多
