Article Citation Count: 8Concomitant Autoimmune Diseases in Patients With Sarcoidosis in Turkey(Turkish League Against Rheumatism, 2020) Yildiz, Fidan; Kobak, Senol; Semiz, Huseyin; Orman, MehmetObjectives: This study aims to determine the frequency and characteristics of autoimmune diseases associated with sarcoidosis patients. Patients and methods: The study included 131 sarcoidosis patients (36 males, 95 females; mean age 46.1 years; range, 20 to 82 years). Demographic, clinical, laboratory and radiological data of patients were evaluated retrospectively. The characteristics of autoimmune diseases associated with sarcoidosis (sarcoidosis-overlap group) patients and isolated sarcoidosis (isolated sarcoidosis group) were analyzed and compared. Results: Concomitant autoimmune diseases were detected in 15 (11.5%) (5 males, 10 females; mean age 50.8 years; range, 26 to 58 years) of the 131 patients with sarcoidosis and their mean disease duration was three months (range, 1 to 30 months). When compared with isolated sarcoidosis patients, more hand finger joint involvement, rheumatoid factor (RF) positivity, higher erythrocyte sedimentation rate (ESR) and less nonsteroidal anti-inflammatory drugs (NSAIDs) usage were found in the sarcoidosis-overlap group (p= 0.035, p=0.049, p= 0.015, p=0.018, respectively). There were no statistically significant differences between the two groups when evaluated for demographic, clinical parameters and disease-modifying antirheumatic drugs usage. Conclusion: Concomitant autoimmune diseases in patients with sarcoidosis may be rarely seen. These patients are characterized with more hand finger joint involvement, RF positivity, higher ESR and less NSAIDs usage. Multicenter, prospective studies involving large numbers of patients are needed to understand whether the association of sarcoidosis-autoimmune diseases is based only on coincidence or on a common etiopathogenesis.Article Citation Count: 5The Efficacy of Lung Volume Reduction Coil Treatment in Patients with Severe Chronic Obstructive Pulmonary Disease (COPD) Type II Respiratory Failure(Dove Medical Press Ltd, 2020) Yildiz, FidanPurpose: Emphysema is a progressive and irreversible disease, proceeding with the decrease in elastic recoil which is connected to tissue damage caused by chronic inflammation. Lung volume reduction coil (LVRC) method in patients with an advanced level of emphysema and irresponsive to medical treatment is shown to provide increase in lung volumes and exercise capacity, decrease in dyspnea, and increase in quality of life. The purpose of this study is to reveal that LVRC treatment is also efficient in severe COPD patients with hypercapnic respiratory failure. Patients and Methods: Eleven cases with severe COPD and emphysema were included in the study. LVRC treatment method was applied in upper lobes of both lungs in patients with severe COPD (FEV1 < %45) and Type-2 respiratory insufficiency (PCO2 55-80 mmHg) who were having medical treatment and CPAP treatment. The patients were followed up for a period of twelve months using arterial blood gas analysis. Results: Beginning with the first month of the LVRC treatment, PCO2 levels were found to be significantly decreased in all patients using arterial blood gas analysis. Conclusion: LVRC method can provide physiological and functional recovery and progress in quality of life in severe COPD cases. It is demonstrated that LVRC treatment caused significant decreases in carbon dioxide levels as well as causing improvement in life quality and respiratory function tests in the patients with hypercapnic respiratory failure.Article Citation Count: 7Malignancy in patients with sarcoidosis(Elsevier Espana Slu, 2021) Kobak, Senol; Yildiz, Fidan; Semiz, Huseyin; Orman, MehmetThe relationship between sarcoidosis and malignancy is not clear yet. We retrospectively evaluated 131 sarcoidosis patients followed-up at the single Rheumatology center. The incidence of malignancies was investigated in this cohort. A total of 6 (4.6%) patients with malignancy were identified in our cohort of 131 patients with sarcoidosis. Hodgkin lymphoma (HL) was detected in three patients, followed by one patient with breast cancer, one patient with thyroid cancer and one patient with testicular cancer. All patients had chronic sarcoidosis with pulmonary involvement, and only 1 patient had acute sarcoidosis with Lofgren's syndrome. HL developed concomitantly with sarcoidosis in one patient while other two patients developed disease before and after sarcoidosis diagnosis. Two patients with solid tumors developed malignancy years before sarcoidosis diagnosis, while one patient developed thyroid cancer during sarcoidosis follow-up. All 6 sarcoidosis-malignancy patients survived after six year years follow up. We found low incidence of malignancy in patients with sarcoidosis in our small cohort. The sarcoidosis-malignancy relationship can only be a coincidence and/or can be explained by a common pathogenesis. New prospective studies involving large patients series are needed in this regard.
