The patient global assessment (PGA) is a reported outcome instrument used to gauge the patient's well-being. We performed a prospective study of patients seen at the University of Cincinnati Sarcoidosis Clinic. Two groups were studied: those at first visit during the time period (initial) and those seen at least one more time by the same physician (follow-up). A total of 1006, including 677 initial, visits occurred during the six-month period. Patients in whom anti-inflammatory treatment was initiated or increased had a significantly lower PGA score (ANOVA p < 0.001, p < 0.05 for increased versus all others). There was no significant difference in initial PGA score based on race, sex, or age. The change in PGA was significantly lower for patients in whom treatment was increased (ANOVA p < 0.001, increased different from all others, p < 0.05). The PGA was significantly lower for patients in whom anti-inflammatory therapy was increased; however, there was overlap between groups., Author(s): Robert P.

One view of sarcoidosis is that the term covers many different diseases. However, no classification framework exists for the future exploration of pathogenetic pathways, genetic or trigger predilections, patterns of lung function impairment, or treatment separations, or for the development of diagnostic algorithms or relevant outcome measures. We aimed to establish agreement on high-resolution CT (HRCT) phenotypic separations in sarcoidosis to anchor future CT research through a multinational two-round Delphi consensus process. Delphi participants included members of the Fleischner Society and the World Association of Sarcoidosis and other Granulomatous Disorders, as well as members' nominees. 146 individuals (98 chest physicians, 48 thoracic radiologists) from 28 countries took part, 144 of whom completed both Delphi rounds. After rating of 35 Delphi statements on a five-point Likert scale, consensus was achieved for 22 (63%) statements. There was 97% agreement on the existence of distinct HRCT phenotypes, with seven HRCT phenotypes that were categorised by participants as non-fibrotic or likely to be fibrotic. The international consensus reached in this Delphi exercise justifies the formulation of a CT classification as a basis for the possible definition of separate diseases. Further refinement of phenotypes with rapidly achievable CT studies is now needed to underpin the development of a formal classification of sarcoidosis. [ABSTRACT FROM AUTHOR]

RationaleClinical trial design in interstitial lung diseases (ILDs) has been hampered by lack of consensus on appropriate outcome measures for reliably assessing treatment response. In the setting of connective tissue diseases (CTDs), some measures of ILD disease activity and severity may be confounded by non-pulmonary comorbidities.MethodsThe Connective Tissue Disease associated Interstitial Lung Disease (CTD-ILD) working group of Outcome Measures in Rheumatology-a non-profit international organisation dedicated to consensus methodology in identification of outcome measures-conducted a series of investigations which included a Delphi process including >248 ILD medical experts as well as patient focus groups culminating in a nominal group panel of ILD experts and patients. The goal was to define and develop a consensus on the status of outcome measure candidates for use in randomised controlled trials in CTD-ILD and idiopathic pulmonary fibrosis (IPF).ResultsA core set comprising specific measures in the domains of lung physiology, lung imaging, survival, dyspnoea, cough and health-related quality of life is proposed as appropriate for consideration for use in a hypothetical 1-year multicentre clinical trial for either CTD-ILD or IPF. As many widely used instruments were found to lack full validation, an agenda for future research is proposed.ConclusionIdentification of consensus preliminary domains and instruments to measure them was attained and is a major advance anticipated to facilitate multicentre RCTs in the field.

We present an updated overview of the hematological involvementassociated with sarcoidosis, including a management approach forcytopenias and revisiting the association with hematologicalmalignancies. Theetiology of cytopenias in sarcoidosis can be attributed to two majoretiopathogenic mechanisms: infiltration of hematopoietic organs suchas the spleen and bone marrow, and autoimmune-mediated cytopenias.With respect to the association with hematological malignancies, itrequires careful evaluation of patients from a chronologicalperspective. Patients must be classified into one of three pathogenicscenarios, including preexisting hematological malignancies,synchronous development of malignancy and sarcoidosis due to commonpredisposing factors, or sarcoidosis as a predisposing factor formalignancies. The association between sarcoidosis and hematologic involvement isbest understood as a pathogenic continuum, with cytopenias andhematologic neoplasms intertwined due to various etiopathogenicmechanisms. These mechanisms include sarcoid infiltration ofhematopoietic organs, common predisposing immunogenetics for thedevelopment of autoimmune cytopenias and malignancies, and anincreased risk of neoplasm development in patients with autoimmunecytopenias. Collaboration among the main specialties involved in theclinical management of these patients is crucial for an earlymonitoring and management. [ABSTRACT FROM AUTHOR]

Background Sarcoidosis is a systemic disease in which the personal environment seems to drive a differentiated disease frequency and clinical expression. The main epidemiological studies suggest a key influence of potential environmentally linked exposures related to the type of occupation, the household, life style, socioeconomic status, and region of residence. Objective To provide an update on how sarcoidosis may be modulated by environmental factors. Data Sources We searched PubMed for epidemiological studies. Synthesis The risk of sarcoidosis is enhanced in people working in jobs related to agriculture, water, construction, metal machining, education, and health, and reduced in those working in jobs mainly centered on personal care. Studies have confirmed seasonal-related peaks of sarcoidosis incidence that follow geographical North-South and West-East gradients. Other personal factors include smoking, personal household exposures, and leisure activities. The evidence pointing to the crucial role of the environment in the etiopathogenesis of sarcoidosis is mounting rapidly. Few diseases so strongly combine geography, environment, gender, and ethnicity as key etiopathogenic factors, with susceptibility to any putative agent being modulated by the individual exposome and genome. Conclusion Geoepidemiological research should focus on evaluating the combined effects of environmental and genetic factors, the identification of clusters of geographically driven exposures, and more precise measurement of all personal exposures (degree of combination, length, and level of exposure)., Author(s): Manuel Ramos-Casals [sup.1], Belchin Kostov [sup.1] [sup.2], Pilar Brito-Zerón [sup.1] [sup.3], Antoni Sisó-Almirall [sup.2], Robert P.
