The prognostic implications of this association are poorly characterized. The aim of this study was to determine the prevalence of SARD and autoimmune markers in a cohort of patients with exposure to silica and assess their impact on prognosis. METHOD We performed a prospective observational study of all patients attending the dedicated silicosis clinic of our pulmonology unit between 2009 and December 2017. Diagnosis was confirmed by a rheumatologist according to Spanish Rheumatology Society criteria. Autoimmune markers, pulmonary function tests, radiological progression, visits to the emergency department and primary care center, and hospital admissions for respiratory causes, and mortality were analyzed. RESULTS Overall, 489 cases of silicosis and 95 cases of exposure were studied. In total, 54 (11.0%) patients with silicosis had SARD: 12 (2.4%) rheumatoid arthritis, 10 (2.0%) systemic lupus erythematosus, 10 (2.0%) systemic sclerosis, 3 (0.6%) Sjögren syndrome, 2 (0.4%) vasculitis associated with anti-neutrophil cytoplasmic antibodies (ANCA +), 6 (1.2%) psoriatic arthritis, 3 (0.6%) ankylosing spondylitis, and 8 (1.6%) other autoimmune diseases with no special features. The patients with SARD visited the emergency room more often (63.0 vs. 42.5%; p = 0.004), and progressed more rapidly (22.2 vs. 11.7%; p = 0.030). CONCLUSIONS The presence of systemic rheumatic autoimmune diseases involves radiological progression and a higher clinical impact.

Several cytokines are activated by their inhalation and can mediate the process of pulmonary fibrosis. The identification of biomarkers could allow an early diagnosis before the development of radiological alterations and help monitor the evolution of patients. The objetive of this study was to determine the clinical significance of specific biomarkers, to estimate their association with the development, severity and/or progression of silicosis, and identify determinants of this evolution. We conducted a prospective observational study in patients attending the pulmonology clinic from 2009 to 2018. Serum levels of the following inflammatory mediators were assessed: interleukin-6 (IL-6), interleukin 2 receptor subunit alpha (IL2R) interleukin 1 beta (IL1B), interleukin-8 (IL-8), tumour necrosis factor-alpha (TNF-α), transforming growth factor-beta1 (TGF-β1), alpha-1 antitrypsin (A...

Research paper thumbnail of Pneumothorax in active pulmonary tuberculosis: resurgence of an old complication?

The work-up and management of this complication differs from that in other types of secondary spontaneous pneumothorax (SSP). Our objective was to assess clinical features and therapeutic modalities of SSP in patients with and without active pulmonary tuberculosis (APTB). All patients diagnosed with SSP seen at the Hospital Xeral of Vigo from January 1990 to June 1995 were candidates for this study. Full clinical, radiological and microbiological examinations were performed in all patients. Invasive procedures (thoracic catheter aspiration, thoracoscopy and thoracotomy) and mean hospital stay were compared in patients with and without APTB. Forty-eight patients with SSP were enrolled. Eleven patients (10 males and one female, mean age 30 i 11 years) had APTB; and 37 patients (31 males and six females, mean age 49 f 20 years) had conditions other than APTB. Chest pain, cough and fever were more frequent in patients with APTB (90% vs 59%; 45% vs 13.5%; 36% vs 5%, respectively). Catheter aspiration was successful in three of 10 (30%) of patients with APTB and in 15/23 (60.86%) of those without APTB. Catheter aspiration time was longer in the former group (25 * 22 days vs 13 * 11 days, P=O.17). As initial treatment, thoracoscopy was performed in seven of 37 (18.91%) of those without APTB and in one of 10 (10%) patients with APTB. For patients with unsuccessful catheter aspiration, thoracoscopy was performed in eight of nine (89%) patients without APTB and in none of the patients with APTB. Thoracotomy was performed in only one of nine (11%) without APTB and in four of seven (57%) patients with APTB. Patients with APTB had a longer hospitalization (41 vs 18 days, P<O.OOl). We concluded that SSP and APTB was a frequent association in our study. Patients with APTB showed a lesser and slower response to catheter aspiration. Despite severe clinical presentation and demand for more invasive procedures, patients with APTB showed a favourable response.
