Values of high-resolution computed tomography and pulmonary function tests in managements of patients with chronic hepatitis C virus infection

AIM:To investigate pulmonary involvement via pulmonaryfunction tests (PFT) and high-resolution computed tomocjraphy(HRCT) in patients with chronic hepatitis C virus (HCV) infection.METHODS:Thirty-four patients with chronic HCV infectionwithout diagnosis of any pulmonary diseases and 10 healthycases were enrolled in the study,PFT and HRCT wereperformed in all cases.RESULTS:A decrease lower than 80% of the predicted valuewas detected in vital capacity in 9/34 patients,in forcedexpiratory volume in one second in 8/34 patients,and in forcedexpiratory flow 25-75 in 15/34 patients,respectively.Carbonmonoxide diffusing capacity (DLCO) was decreased in 26/34patients.Findings of interstitial pulmonary involvement weredetected in the HRCT of 16/34 patients.Significant differencewas found between controls and patients with HCV infection infindings of HRCT (X~2=4.7,P=0.003).Knodell histologicalactivity index (KHAI) of 28/34 patients in whom liver biopsywas applied was 9.0±4.7.HRCT findings,PFT values and DLCOwere not affected by KHAI in patients with HCV infection.Inthese patients,all the parameters were related with age.CONCLUSION:We suggest that chronic hepatitis C virusinfection may cause pulmonary interstitial involvementwithout evident respiratory symptoms.     

Clinicopathological features and prognostic factors associated with gastroenteropancreatic mixed neuroendocrine non-neuroendocrine neoplasms in Chinese patients

BACKGROUND The incidence of mixed neuroendocrine-non-neuroendocrine neoplasms(MiNEN)is low.To improve our understanding of this rare tumor type and optimally guide clinical treatment,associated risk factors,clinical manifestations,and prognosis must be explored.AIM To identify risk factors that influence the prognosis of patients with gastroenteropancreatic MiNEN(GEP-MiNEN).METHODS We retrospectively analyzed the clinical data of 46 patients who were diagnosed with GEP-MiNEN at the First Affiliated Hospital of Bengbu Medical College(Anhui,China)between January 2013 and December 2017.Risk factors influencing the prognosis of the patients were assessed using Kaplan-Meier curves and cox regression models.We compared the results with 55 randomly selected patients with gastroenteropancreatic GEP neuroendocrine tumors,47 with neuroendocrine carcinomas(NEC),and 58 with poorly differentiated adenocarcinoma.RESULTS Among the 46 patients with GEP-MiNEN,thirty-five had gastric tumors,nine had intestinal tumors(four in the small intestine and five in the colon and rectum),and two had pancreatic tumors.The median age of the patients was 66(41-84)years,and the male-to-female ratio was 2.83.Thirty-three(71.7%)patients had clinical stage III and IV cancers.Distant metastasis occurred in 14 patients,of which 13 had metastasis to the liver.The follow-up period was 11-72 mo,and the median overall survival was 30 mo.Ki-67 index≥50%,high proportion of NEC,lymph node involvement,distant metastasis,and higher clinical stage were independent risk factors affecting the prognosis of patients with GEP-MiNEN.The median overall survival was shorter for patients with NEC than for those with MiNEN(14 mo vs 30 mo,P=0.001),but did not significantly differ from those with poorly differentiated adenocarcinoma and MiNEN(30 mo vs 18 mo,P=0.453).CONCLUSION A poor prognosis is associated with rare,aggressive GEP-MiNEN.Ki-67 index,tumor composition,lymph node involvement,distant metastasis,and clinical stage are important factors for patient prognosis.     

血清骨桥蛋白水平与类风湿关节炎活动性的关系及在伴肺间质病变中的意义

Objective To investigate the association between serum level of osteopotin (OPN) and disease activity of rheumatoid arthritis (RA) patients, and explore the importance of OPN in the pathogenesis of interstitial lung disease (ILD) in RA. Methods Sixty-five RA patients and 20 healthy controls were pros-pectively enrolled. RA patients were divided into active group (n=43) and inactive group (n=22), and ILD groups (n=24) and non-ILD group (n=41). Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum levels of OPN in patients with RA and healthy controls, and the relationship between OPN and other clinical and laboratory findings were analyzed. Results ① Serum OPN tended to be significantly higher in RA patients (median, 18.0 ng/ml) than in the healthy controls (median, 14.3 ng/ml), P<0.01; ②The serum level of OPN in RA patients showed a significant positive correlation with the course of disease, numbers of tender joints , ESR and CRP, but no positive relationship was found in number of swollen joints; ③ The serum level of OPN was significantly higher in RA-ILD patients (median, 20.0 ng/ml) than that in non-lLD (median, 17.0 ng/ml, P<0.05). And there was remarkable negative correlation between the concentration of serum OPN and the value of PaO2, but no association was found with pulmonary function %VC and %DLCO. ④ Compared with the non-ILD group, the ILD group had more active disease in terms of tender joint counts and swollen joint counts, ESR, CRP (P<0.01) and the serum titer of RF-IgM, (P<0.05). Conclusion OPN plays a role in the pathogenesis of RA and is related to the disease activity. It may serve as an active disease inflammatory marker of RA . OPN may be involved in the pathogenesis of RA related ILD and is associated with the severity of pulmonary damage.

Development of Microscopic Polyangiitis in Patients with Chronic Airway Disease

Microscopic polyangiitis (MPA) is a rare systemic vasculitis syndrome, which is often accompanied by positive myeloperoxidase-specific antineutrophil cytoplasmic antibody (MPO-ANCA). While pulmonary involvement of MPA consists mainly of diffuse alveolar hemorrhage and interstitial pneumonia, bronchiectasis has been reported as a pulmonary lesion in association with MPA. To investigate the clinical features of patients with MPA, focusing on the presence or the absence of preceding chronic airway diseases (CAD), we conducted a retrospective observational study of 26 patients in the last 13 years at Saga University Hospital. The clinical records and radiologic chest examinations were reviewed retrospectively. Pulmonary manifestations were alveolar hemorrhage in 3 patients (12%) and interstitial pneumonia in 5 (19%). Bronchiectasis, defined by the findings of chest radiograph and computed tomography, was found in 9 patients (35%). Four patients (15%) with bronchiectasis and one patient (4%) with chronic bronchitis had experienced chronic bronchial suppuration prior to the onset of MPA. Ten patients were classified as having chronic airway disease (CAD) before the onset of MPA. MPO-ANCA tended to be lower in the CAD group than in the non-CAD group. None of the patients in the CAD group had pulmonary hemorrhage or interstitial pneumonia. Only one patient (10%) in the CAD group died within 90 days of the onset of MPA, while 7 (43.8%) of the non-CAD group died. Our study suggests that MPA may result in part from CAD and that the clinical course of MPA with CAD may be different from MPA without CAD.     

Pulmonary interstitial fibrosis as a presenting manifestation in perinuclear antineutrophilic cytoplasmic antibody microscopic polyangiitis

Microscopic polyangiitis (MPA) is one of the vasculitides that is included in the pulmonary renal syndromes. Pathologically, MPA has been defined as necrotizing vasculitis with few or no immune deposits, primarily affecting small vessels including arterioles, venules, or capillaries. Pulmonary interstitial fibrosis (PIF) as an accompanying manifestation in MPA has not been widely appreciated. In the present study, we report six cases of MPA at our institution with radiographic evidence of PIF that was apparent before any treatment was administered. All had biopsy evidence of renal disease that was consistent with MPA as well as positive serum perinuclear antineutrophilic cytoplasmic antibody titers. Hemoptysis was observed in approximately one half of the patients. As determined by CT of the chest, PIF was detected in all of the patients and was often present years before a diagnosis of MPA was made. We conclude that PIF may occur as a pulmonary manifestation of MPA. Further appreciation of this finding may lead to more data with respect to the incidence of PIF in MPA, and to a better understanding of the mechanisms that are involved in the development of this finding.     

Pulmonary TB and NTM lung disease: comparison of characteristics in patients with AFB smear-positive sputum.

OBJECTIVE: To compare the clinical and radiographic features of pulmonary tuberculosis (PTB) and non-tuberculous mycobacteria (NTM) lung disease in patients with acid-fast bacilli (AFB) positive sputum specimens. DESIGN: The initial clinical and radiographic features of 229 PTB patients were compared with those of 70 patients with NTM lung disease. The most commonly involved organisms in the NTM lung disease cases were Mycobacterium avium complex (n = 38, 54%) and M. abscessus (n = 26, 37%). RESULTS: Clinical and radiographic findings that were more common in patients with NTM lung disease than in PTB patients were: older age (P < 0.001), non-smoker (P < 0.001), history of previous TB treatment (P < 0.001), absence of pleural effusion (P = 0.017), involvement of middle and/or lower lung zones (P = 0.007), and bilateral disease (P = 0.005). Multivariate analysis showed that older age (> or = 40 years), non-smoker, previous TB treatment, absence of pleural effusion and involvement of middle and/or lower lung zones were significant independent predictors for NTM lung disease. CONCLUSIONS: There is considerable overlap in the clinical and radiographic appearances of PTB and NTM lung disease. The isolation and identification of causative organisms are mandatory for a correct diagnosis in patients with AFB-positive sputum specimens.

Pleural effusion as a presenting manifestation of giant cell arteritis

Summary Pulmonary involvement is rare in giant cell arteritis (GCA). Only a few cases have been reported, manifested by interstitial infiltration, pulmonary nodules, pulmonary artery vasculitis, and granuloma formation. Moreover, only 3 previous cases of pleural effusion associated with GCA have been described. Herein we report a 67-year-old woman with biopsy-proven temporal arteritis, presented with prolonged fever, weight loss, cough and pleural effusion. ELISA test for the presence of anti- proteinase-3 antibodies was negative. The importance of the anti-neutrophil cytoplasmic-antibodies (ANCA) examination in the differential diagnosis from other vasculitides with pulmonary involvement is discussed.
