Practical Management of Respiratory Comorbidities in Patients with Rheumatoid Arthritis.

Rheumatol Ther. 2017 Aug 14;:

Authors: Bluett J, Jani M, Symmons DPM

Abstract
Lung disease is one of the most common causes of extra-articular morbidity and mortality in patients with rheumatoid arthritis (RA). Development of pulmonary manifestations may be due to the systemic disease itself; to serious respiratory adverse events such as pneumonitis and infections secondary to therapy; or to lifestyle habits such as smoking. Rheumatologists often need to make important treatment decisions and plan future care in RA patients with respiratory comorbidities, despite the absence of clear evidence or consensus. In this review we evaluate the clinical assessment and management of RA-associated interstitial lung disease, bronchiectasis, serious (including opportunistic) infection, and smoking-related diseases. We summarize the international recommendations for the management of such conditions where available, refer to published best practice on the basis of scientific literature, and propose practical management suggestions to aid informed decision-making.

Serological and morphological prognostic factors in patients with interstitial pneumonia with autoimmune features.

BMC Pulm Med. 2017 Aug 14;17(1):111

Abstract
BACKGROUND: To identify the prognostic factors for survival in patients with interstitial pneumonia with autoimmune features (IPAF) who meet the serological domain of the IPAF criteria.
METHODS: We retrospectively analysed 99 IPAF patients who met the serological domain and were hospitalised at the Respiratory Medicine Unit of Kurashiki Central Hospital from 1999 to 2015. The high-resolution computed tomography findings were usual interstitial pneumonia (UIP; n = 1), non-specific interstitial pneumonia (NSIP; n = 63), NSIP with organizing pneumonia (OP) overlap (n = 15), and OP (n = 20). One patient who had radiological UIP pattern, and met the serological and clinical domains was excluded. The clinical characteristics, radiological findings, administered therapy, and prognosis of the remaining 98 IPAF patients who met the serological and morphological domains were analysed.
RESULTS: The median age of the 98 IPAF patients was 68 years, and 41 (41.8%) of them were men. Twelve (12.2%) of the 98 IPAF patients developed other characteristics and were diagnosed with connective tissue disease (CTD) later during the median follow-up of 4.5 years. Univariate Cox analysis revealed systemic sclerosis (SSc)-specific and SSc-associated antibodies (ANA nucleolar pattern, ANA centromere pattern, anti-ribonucleoprotein and anti-Scl-70) positive IPAF, radiological NSIP pattern, bronchoalveolar lavage fluid lymphocytes >15%, and age as significant prognostic factors for survival. Multivariate Cox analysis revealed radiological NSIP pattern (hazard ratio [HR], 4.48; 95% confidence interval [CI], 1.28-15.77, p = 0.02) and age (HR, 1.07; 95% CI, 1.02-1.11, p = 0.01) were significantly associated with worse survival.
CONCLUSIONS: We confirmed that radiological NSIP pattern and age are poor prognostic factors for the survival of IPAF patients. This study suggested that the autoantibodies that are highly specific for certain connective tissue diseases might be less important for the prognosis of IPAF compared with the radiological-pathological patterns. The relatively high proportion of IPAF patients who developed CTD later suggests the importance of careful observation for evolution to CTD in IPAF.

Bronchoscopic modalities to diagnose sarcoidosis Imprimer Envoyer
Lundi, 14 Août 2017 07:24
imagePurpose of review: Several studies have investigated different bronchoscopic techniques to obtain tissue diagnosis in patients with suspected sarcoidosis when the diagnosis cannot be based on clinicoradiographic findings alone. In this review, we will describe the most recent and relevant evidence from different bronchoscopic modalities to diagnose sarcoidosis. Recent findings: Despite multiple available bronchoscopic modalities to procure tissue samples to diagnose sarcoidosis, the vast majority of evidence favors endobronchial ultrasound transbronchial needle aspiration to diagnose Scadding stages 1 and 2 sarcoidosis. Transbronchial lung cryobiopsy is a new technique that is mainly used to aid in the diagnosis of undifferentiated interstitial lung disease; however, we will discuss its potential use in sarcoidosis. Summary: This review illustrates the limited information about the different bronchoscopic techniques to aid in the diagnosis of pulmonary sarcoidosis. However, it demonstrates that the combination of available bronchoscopic techniques increases the diagnostic yield for suspected sarcoidosis.
