Squamous Pulmonary Neoplasia Grafted on Lesions of Pulmonary Tuberculosis Sequelae.

ABSTRACT: Clinical symptoms of hemoptysis, chest pain, dyspnea, night sweats and weight loss seen in a patient known for 14 years with pulmonary tuberculosis with sequelae lesions, will always guide the diagnose to a reactivated pulmonary tuberculosis. Yet, in this case, the latest pulmonary radiography revealed newly emerging bilateral lesions with the appearance of a macronodular opacity of medium intensity, discreetly non-homogeneous, located apical-sub-clavicular on the right side, but also with an apical-sub-clavicular cavity lesion on the left side, well defined, with uniform opaque content, and clear-cut outline. Complementary examinations, computed tomography and biopsy bronchoscopy, confirmed the diagnosis of upper right lobe pulmonary tumor with suspicion of aspergilloma in the upper left lobe.

Project description:Bacteria in lung play an important role in sustaining lung health. Understanding the characteristics of bacteriomes in lesions of pulmonary tuberculosis (TB) patients, who excrete Mycobacterium tuberculosis (MTB), is important for TB prevention and effective treatment. METHODS: In this study, bacteriomes in lesions from TB patients excreting bacteria (TB-E) and those from TB patients not excreting bacteria (TB-NE) with matched normal lung tissues (NT) were compared by 16S rRNA sequencing. Bacterial MetaCyc functions in TB lesions were also predicted by PICRUSt2 tool. Alpha diversity of bacteria, including Chao 1 and Shannon indexes, for TB-E was significantly higher than those in TB-NE and NT; while for TB-NE group, Chao 1 index was higher than that in NT group. Predominant phyla in TB lesions and NT were Proteobacteria, Actinobacteria, Firmicutes, and Bacteroidetes, but analysis of similarity (ANOSIM, p < 0.001) revealed significantly different bacterial compositions among TB-E, TB-NE and NT samples. As for bacteriomes in TB lesions, a strong association (ANOSIM, p < 0.001) was observed with the status of MTB excretion. Indicator genera identified in TB-E and TB-NE demonstrated distinctive micro-ecological environments of TB lesions from patients with different clinical manifestations. Co-occurrence analysis revealed a densely-linked bacterial community in TB-NE compared to that in TB-E. MetaCyc functions responsible for menaquinone synthesis and chorismate metabolism that could potentially impact the persistent-state and nutrient metabolism of MTB were enriched in TB-E samples. While in TB-NE samples, enrichment of bacterial MetaCyc function responsible for heme b synthesis might contribute to TB pathology through ferroptosis. Bacteriomes and their MetaCyc functions in TB lesions are elucidated, and they are associated with status of MTB excretion among pulmonary TB patients. These results serve as a basis for designing novel strategies for preventing and treating pulmonary TB disease.
