Epidemiology of interstitial lung diseases in Greece
ABSTRACT Few data are available on the epidemiology of interstitial lung diseases (ILDs), especially after the current classification of idiopathic interstitial pneumonias. The aim of this study is to provide data on the epidemiology of ILDs in Greece, under the ATS/ERS international consensus.
Departments of Pneumonology were contacted and asked to complete a questionnaire for every case of ILD that was alive on 2004 as well as for every new case from 1st January 2004 to 31st December 2004. Questions on the patients' demographic data, the exact diagnosis and the procedures used to establish the diagnosis were included. Centers covering about 60% of the Greek population have been analyzed.
A total of 967 cases have been registered. The estimated prevalence of ILDs is 17.3 cases per 100,000 inhabitants. The estimated annual incidence of ILDs is 4.63 new cases per 100,000 inhabitants. The most frequent disease is sarcoidosis (34.1%), followed in decreasing order by idiopathic pulmonary fibrosis (19.5%), ILD associated with collagen vascular diseases (12.4%), cryptogenic organizing pneumonia (5.3%), histiocytosis (3.8%), and hypersensitivity pneumonitis (2.6%). Unclassified ILD or not otherwise specified accounted for the 8.5% of prevalent cases.
These data suggest that sarcoidosis and idiopathic pulmonary fibrosis are the most frequent ILDs in our population. In comparison with the few previous reports, interesting dissimilarities have been observed.

ABSTRACT: Recent studies suggest that the incidence of idiopathic pulmonary fibrosis (IPF) is rising. Accurate epidemiological data on IPF, however, are sparse and the results of previous studies are contradictory. This study was undertaken to gain insight into the various methods used in the epidemiological research of IPF, and to get accurate and comparable data on these different methodologies. A systematic database search was performed in order to identify all epidemiological studies on IPF after the previous guidelines for diagnosis and treatment were published in 2000. Medline (via Pubmed), Science Sitation Index (via Web of Science) and Embase databases were searched for original epidemiological articles published in English in international peer-reviewed journals starting from 2001. After pre-screening and a full-text review, 13 articles were accepted for data abstraction. Three different methodologies of epidemiological studies were most commonly used, namely: 1) national registry databases, 2) questionnaire-based studies, and 3) analysis of the health care system's own registry databases. The overall prevalence and incidence of IPF varied in these studies between 0.5--27.9/100,000 and 0.22--8.8/100,000, respectively. According to four studies the mortality and incidence of IPF are rising. We conclude that there are numerous ways to execute epidemiological research in the field of IPF. This review offers the possibility to compare the different methodologies that have been used, and this information could form a basis for future studies investigating the prevalence and incidence of IPF.BMC Pulmonary Medicine 08/2013; 13(1):53.

- "Epidemiologic studies in Italy, Belgium, Greece, Spain, United States and Finland have revealed that the diagnosis has been confirmed by SLB in 28–38% of the cases [17-22]. Questionnaire-based national surveys have shown that in Greece and Spain approximately 31% of the patients with IPF were diagnosed by SLB [19,22]. In the major clinical trials conducted in the past decade, the current diagnostic criteria for IPF have been used which may provide some enlightenment on the frequency of SLB. "
ABSTRACT: A new international statement defines usual interstitial pneumonia (UIP) which is a histological and radiological form of idiopathic pulmonary fibrosis (IPF) more precisely than previously. In the diagnosis of IPF, either in high resolution computed tomography (HRCT) a UIP pattern must be present or alternatively specific combinations of HRCT and surgical lung biopsy findings can be accepted. In about two third of the cases IPF can be diagnosed by clinical and radiological criteria. Thus surgical lung biopsy is needed in about one third of cases to achieve the ultimate diagnosis, which requires multidisciplinary cooperation. In large clinical trials conducted during the last decade, lung biopsy was performed in about 30--60% of the cases. The most serious complication of lung biopsy is mortality within 30 days after the procedure, with a frequency of about 3--4% reported in most studies. Because of the histological variability, surgical lung biopsy should be taken from a minimum of two lobes. The number of fibroblast foci in surgical lung biopsy has been shown to correlate with survival in several studies.Respiratory research 04/2013; 14(1):43.

ABSTRACT: Interstitial lung diseases (ILD) are a group of extremely heterogeneous conditions (over 200), with low prevalence, but in most cases with severe impact on the quality of life and survival of the patients. The ILD group comprises: idiopathic pulmonary fibrosis, sarcoidosis, hypersensitivity pneumonitis, colagen diseases, vasculitis, eosinophilic pneumonia etc. The prevalence of these diseases is unknown in Romania; the accurate diagnosis needs access to special investigations and expertise with this group of diseases. The authors propose the initiation of a National Registry for Interstitial Lung Diseases and Sarcoidosis (REGIS), based on the lessons learned from other national ILD) registries, which should allow building-up an extended clinical expertise in ILD, evaluating epidemiological data, creating an educational platform for young physicians, better understanding of the outcome and prognosis of these diseases, shaping Romanian Guidelines for the diagnosis and management of ILD, using the data base for clinical research. The registry is started as a pilot in two Romanian centres: "Marius Nasta" Institute of Pneumology in Bucharest and Pneumology Clinic, "Victor Babey" Infectious Diseases Hospital Timişoara. After refining the inclusion criteria for the data base, editing guidelines for ILD diagnosis and launching the registry website, other Romanian centres with interest in ILD will also be able to feed information.61(1):20-4.
