“…This disease is prevalent in developing countries, but it is rare in industrialized countries, and the majority of people with this disease are immigrants from third world countries [ 7 ]. The epidemiology of developing countries shows that exposure to wood smoke can play an etiologic role in a wide range of adult medical diseases [ 5 , 8 ]. Some studies claim that tuberculosis can be a risk factor for developing anthracosis, and in some studies, the comorbidity rate was reported to be 37 % [ 9 ].…”

Background Anthracosis and anthracofibrosis are attributed to the deposition of carbon particles along with fibrosis, adhesion, narrowing, and collapse. There has been no study on the characteristics of the pleural fluid in anthracosis. The present study analyzed the biochemical characteristics of pleural effusion in patients with pulmonary anthracosis. Patients and methods The study is a cross-sectional study which included patients who were referred to the Afzalipour Hospital in Kerman, eastern Iran. Between April 2018 and October 2019, patients who had undergone bronchoscopy and were diagnosed with anthracosis and pleural effusion were selected through the census method. The characteristics of the pleural fluid were analyzed for protein, albumin, LDH, PH, Triglyceride, cholesterol, glucose, and cytology. Concomitant blood samples were examined for LDH, albumin, total protein, and glucose. After it was specified whether the pleural effusion was transudative or exudative, patients with lymphocyte-dominant exudative pleural fluid became candidates for thoracoscopy. Result 106 patients (6.21 %) of 1705 patients had anthracosis and anthracofibrosis; 37 of these patients (34.9 %) had coexisting pleural effusion. 31 patients gave written informed consent for thoracentesis. The mean age of the patients was 76.48 ± 8.81. In addition, 67.74 % of the patients were female. Pleural effusion was transudative in 29 (93.54 %). Except for one case, all patients had diffuse anthracofibrosis and 67.74 % of the patients had a history of baking bread. Conclusion According to the findings of this study, most cases had transudative lymphocyte-dominant pleural fluid with mostly diffuse anthracofibrosis. In addition, this condition is more prevalent in women, with a prevalence of approximately twice that of men.

Introduction Anthracosis is black discoloration of the bronchi, which can sometimes cause anthracofibrosis. Usually, exposure to biomass fuel, air pollution, or smoke at the workplace causes it. The objective of the current study was to determine the association between tuberculosis and anthracosis. Methods Patients with chronic dyspnea, dry cough, and infiltrates or mass lesions on chest X-rays underwent bronchoscopic lavage and biopsy where needed. Patients were divided into two groups on the basis of anthracosis on bronchoscopy. Diagnosis of tuberculosis was made on bronchial wash acid-fast bacilli smear, mycobacterial culture, or Xpert Mycobacterium tuberculosis (MTB) rifampicin (RIF) assay. Results Tuberculosis was diagnosed by bronchoscopy in 68/173 (39.30%) patients with anthracosis which was significantly higher (p-value 0.020) than the control group (43/159, 27.04%). Most of the cases (54/68, 79.41%) had positive Xpert assay. The male-to-female ratio was 3:1, and all the females with anthracosis were homemakers and used biomass fuel. Conclusion Patients with exposure to smoke are prone to develop anthracosis. The presence of anthracosis is associated with the development of tuberculosis. Appropriate investigations for tuberculosis must be done in subjects undergoing bronchoscopy who are found to have anthracosis. Expanding understanding among the masses regarding the hazards of using biomass fuel in closed spaces can be a crucial measure toward diminishing the chance of developing anthracosis and the concomitant risk of tuberculosis.
