OBJECTIVE:
To describe the characteristics of a cohort of patients with lung-dominant connective tissue disease (LD-CTD).METHODS:
This was a retrospective study of patients with interstitial lung disease (ILD), positive antinuclear antibody (ANA) results (≥ 1/320), with or without specific autoantibodies, and at least one clinical feature suggestive of connective tissue disease (CTD).RESULTS:
Of the 1,998 patients screened, 52 initially met the criteria for a diagnosis of LD-CTD: 37% were male; the mean age at diagnosis was 56 years; and the median follow-up period was 48 months. During follow-up, 8 patients met the criteria for a definitive diagnosis of a CTD. The remaining 44 patients comprised the LD-CTD group, in which the most prevalent extrathoracic features were arthralgia, gastroesophageal reflux disease, and Raynaud''s phenomenon. The most prevalent autoantibodies in this group were ANA (89%) and anti-SSA (anti-Ro, 27%). The mean baseline and final FVC was 69.5% and 74.0% of the predicted values, respectively (p > 0.05). Nonspecific interstitial pneumonia and usual interstitial pneumonia patterns were found in 45% and 9% of HRCT scans, respectively; 36% of the scans were unclassifiable. A similar prevalence was noted in histological samples. Diffuse esophageal dilatation was identified in 52% of HRCT scans. Nailfold capillaroscopy was performed in 22 patients; 17 showed a scleroderma pattern.CONCLUSIONS:
In our LD-CTD group, there was predominance of females and the patients showed mild spirometric abnormalities at diagnosis, with differing underlying ILD patterns that were mostly unclassifiable on HRCT and by histology. We found functional stability on follow-up. Esophageal dilatation on HRCT and scleroderma pattern on nailfold capillaroscopy were frequent findings and might come to serve as diagnostic criteria. 相似文献2.

The initial evaluation of patients with interstitial lung disease (ILD) primarily
involves a comprehensive, active search for the cause. Autoantibody assays, which can
suggest the presence of a rheumatic disease, are routinely performed at various
referral centers. When interstitial lung involvement is the condition that allows the
definitive diagnosis of connective tissue disease and the classical criteria are met,
there is little debate. However, there is still debate regarding the significance,
relevance, specificity, and pathophysiological role of autoimmunity in patients with
predominant pulmonary involvement and only mild symptoms or formes frustes of
connective tissue disease. The purpose of this article was to review the current
knowledge of autoantibody positivity and to discuss its possible interpretations in
patients with ILD and without clear etiologic associations, as well as to enhance the
understanding of the natural history of an allegedly new disease and to describe the
possible prognostic implications. We also discuss the proposition of a new term to be
used in the classification of ILDs: lung-dominant connective tissue disease. 相似文献

In the 2013 reclassification of the idiopathic interstitial pneumonias (IIPs), two rare IIPs (idiopathic lymphoid interstitial pneumonia (LIP), idiopathic pleuroparenchymal fibroelastosis (IPPFE)) and two rare histologic patterns (acute fibrinous and organizing pneumonia (AFOP), bronchiolocentric pattern of interstitial pneumonia (BPIP)) are described. All these entities are rare with small series published to date, mostly containing primary and secondary forms of disease. LIP is histologically characterized by diffuse polyclonal lymphoid cell infiltrate surrounding the airways and expanding the interstitium. Thin‐walled cysts and diffuse ground glass are considered the typical radiologic features. The clinical course is highly variable with corticosteroid responsiveness evident in approximately half of cases. IPPFE is defined histologically by coexisting upper lobe pleural and intra‐alveolar fibrosis with elastosis. Dense subpleural irregular fibrosis and consolidation are the cardinal radiologic features. A history of recurrent lower respiratory tract infection is frequent. Responses to immunomodulation have not been reported and the rate of progression appears to be highly variable. AFOP is a rare histologic pattern lying within the spectrum of acute/subacute lung injury, characterized by organizing pneumonia and intra‐alveolar fibrin deposition without hyaline membranes. BPIP is characterized histologically by fibrosis and/or inflammation confined to the alveolar interstitium around bronchovascular bundles, overlapping with peribronchial metaplasia and fibrosis in some series. Currently, AFOP and BPIP are both best viewed as histological entities rather than true clinical disorders, in the absence of characteristic associated imaging patterns and clinical features. 相似文献

Pneumomediastinum as a complication of interstitial pneumonia with leakage of air into the mediastinum or subcutaneous tissues
is a rare complication of dermatomyositis (DM). Herein we report a case of pneumomediastinum complicating polymyositis (PM),
which is usually associated with DM. A 61-year-old man was hospitalized in our department because of deterioration of interstitial
pneumonia. Treatment with high-dose corticosteroid and cyclosporin A steadily improved his interstitial pneumonia. Two weeks
later, he developed subcutaneous emphysema and chest X-ray showed pneumomediastinum. Both subcutaneous emphysema and pneumomediastinum
improved gradually without any additional treatment. 相似文献

BackgroundUnderstanding health-related quality of life (HRQL) in patients with interstitial lung disease (ILD) provides insight into disease burden and treatment effects on patients’ well-being. We examined HRQL in a multiracial Asian ILD cohort using the King’s brief ILD (K-BILD) and EuroQol 5-dimension-3-level (EQ5D-3L) questionnaires and their associations with several clinical variables.MethodsThis was a single-centre cross-sectional study of ILD patients in a university-affiliated tertiary public hospital in Singapore. All patients completed two self-administered HRQL questionnaires upon study entry, and their clinical information was retrieved from electronic medical records.ResultsNinety-nine patients (56% male, 75% Chinese) were included. The median (interquartile range) age was 63 (54–72) years. The most common ILD diagnosis was connective tissue disease-related ILD (n=51, 52%), followed by idiopathic pulmonary fibrosis (n=27, 27%). The mean (standard deviation) scores for the EQ5D-3L utility value, EQ5D Visual Analogue Scale (VAS) and K-BILD total were 0.806 (0.284), 75.1 (12.8) and 63.9 (14.3), respectively. A moderate correlation was found between the EQ5D-3L and K-BILD total and domain scores. The HRQL scores also correlate moderately with the modified Medical Research Council dyspnoea scale (mMRC) scores. There was a weak-to-moderate correlation between HRQL and forced vital capacity (FVC), carbon monoxide diffusing capacity (DLCO) and Charlson comorbidity index. Multiple linear regression showed a significant association of K-BILD total [beta coefficient 0.244, 95% confidence interval (CI): 0.075–0.414; P=0.005], K-BILD ‘breathlessness and activities’ (beta coefficient 0.448, 95% CI: 0.192–0.703; P=0.001), and the ‘psychological’ domain (beta coefficient 0.256, 95% CI: 0.024–0.488; P=0.031) with DLCO %pred after adjustment for age, sex, BMI, race, smoking history, comorbidities, FVC %pred and ILD diagnosis. Non-Chinese race was a predictor of better K-BILD ‘psychological’ domain (beta coefficient 8.680, 95% CI: 0.656–16.704; P=0.034) after adjustment.ConclusionsHRQL is significantly impaired in ILD patients, and low DLCO is a strong predictor of this impairment 相似文献

A systematic approach is recommended to search for clinical and biological features of connective tissue disease (CTD) in any patient with interstitial lung disease (ILD). In the diagnostic approach to ILD, a diagnosis of CTD should be considered particularly in women and subjects younger than 50 years, and in those with an imaging and/or pathological pattern of non‐specific interstitial pneumonia. However, the diagnosis of CTD may be difficult when ILD is the presenting or the dominant manifestation of CTD. A proportion of patients with ILD present symptoms that belong to the spectrum of CTD and/or biological autoimmune features, but do not fulfil diagnostic criteria for a given CTD. Some imaging and histopathological patterns may also suggest the presence of an underlying CTD. Although studies published to date used heterogeneous definitions and terminology for this condition, evidence is accumulating that even limited CTD features are relevant regarding symptoms, imaging features, pathological pattern and possibly evolution to overt CTD, whereas the impact on prognosis needs confirmation. Conversely, autoantibodies alone do not seem to impact the prognosis or management in patients with otherwise typical idiopathic pulmonary fibrosis and no extra‐pulmonary manifestation. A collective international multidisciplinary effort has proposed a uniform definition and criteria for ‘interstitial pneumonia with autoimmune features’, a condition characterized by limited CTD features occurring in the setting of ILD, with the aim of fostering future clinical studies. Referral of ILD patients suspect to have CTD to a rheumatologist and possibly multidisciplinary discussion may contribute to a better management. 相似文献

We herein describe a 16-year-old boy with pneumomediastinum, pneumothorax, and subcutaneous emphysema as the initial symptoms
of dermatomyositis (DM). His pneumomediastinum disappeared after strict bed rest and he was thereafter successfully treated
with oral prednisolone and cyclosporine A. His condition was further complicated with mild interstitial lung disease, arrhythmia,
and skin ulcers on his fingertips, right elbow, ear, and sacral region. Pneumomediastinum is a rare complication of DM and
its pathogenesis remains unclear. We review the literature and discuss the possible mechanism of this disease. 相似文献

目的 与普通型间质性肺炎(usual interstitial pneumonia,UIP)进行比较分析,探讨特发性非特异性间质性肺炎(idiopathic nonspecific interstitial pneumonia,INSIP)的疾病特征和预后以及与UIP的鉴别诊断.方法 发对经电视胸腔镜或小切口开胸肺活检诊断的21例INSIP患者和18例UIP患者的临床-影像-病理学资料及疗效、预后进行比较分析.结果 INSIP多见于40~50女性,临床表现无特异性,主要表现为活动后气促、咳嗽、咯痰、双下肺可有或无吸气相爆裂音;高分辨率CT(HRCT)表现为双肺弥漫分布的磨玻璃样淡斑片状和不规则网织状阴影,部分可有蜂窝肺.INSIP的病理特征为病变进展相对一致,按病理表现可分为细胞型、纤维化型和混合型.与UIP相比,纤维母细胞灶、肌硬化、镜下蜂窝肺和肺泡结构改建的检出率在INSIP和UIP分别是19.05%和100%(P<0.001),19.05%和88.89%(P<0.05),23.81%和94.44%(P<0.01),33.33%和100%(P<0.01).两者对糖皮质激素的反应率分别为76.19%和38.89%(P<0.01),各型INSIP的预后均明显好于UIP.结论 经 INSIP的一般临床表现差异不明显,HRCT对疑难病例的鉴别诊断有帮助,明确诊断依赖肺活检病理诊断;纤维母细胞灶、伴胶原沉积的瘢痕化和蜂窝变组成不同时相的病变共同构成诊断UIP的形态特征,也是与INSIP的鉴别要点. 相似文献

Background
The purpose of this study was to clarify the clinico-radio-pathological characteristics and prognostic factors of unclassifiable-idiopathic interstitial pneumonias (U-IIPs) diagnosed by surgical lung biopsy.Methods
Among 86 patients with interstitial pneumonia who underwent surgical lung biopsy from January 2005 to September 2013, 33 (38.4%; 16 male patients; mean age, 64.4 ± 8.8 years) were diagnosed with U-IIPs. They were subsequently categorized into rapidly progressive (n = 7), slowly progressive (n = 7), and stable (n = 19) groups based on the decrease of the percent predicted forced vital capacity or percent predicted diffusing capacity of the lung carbon monoxide and the occurrence of acute exacerbation. The clinico-radio-pathological features and survival rates of the patients who were followed up for at least 3 years were examined. These cases were reevaluated retrospectively by multidisciplinary discussion.Results
The rapidly progressive group had a significantly poorer prognosis than that of the other groups (p < 0.0001). Although there were no significant pattern differences on the chest high-resolution computed tomography, the fibrosis scores were significantly higher in the rapidly progressive group (p = 0.002). Furthermore, the percentage of fibroblastic foci assessed by the pathological analysis was also significantly higher in the rapidly progressive group (p = 0.006). Nine (27.3%) patients developed connective tissue diseases during follow-up.Conclusions
The radiologic patterns were not significantly different among the three clinical U-IIPs subgroups. Nevertheless, our findings suggested that the fibrosis scores and the percentage of fibroblastic foci could provide a prognostic assessment in U-IIPs. 相似文献19.
