Heliyon 2024; 10:e33181. [PMID: 39005927 PMCID: PMC11239688 DOI: 10.1016/j.heliyon.2024.e33181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 06/10/2024] [Accepted: 06/15/2024] [Indexed: 07/16/2024] Open
Abstract
Trichomonas tenax, an oral commensal parasite commonly found in the human mouth, is associated with periodontitis and poor oral hygiene. However, it has also been identified in the bronchoalveolar lavage fluid (BALF) of individuals with lung diseases. Notably, significant quantities of T. tenax have been isolated following bronchoscopy in cases of empyema and acute respiratory distress syndrome (ARDS). Furthermore, research has demonstrated its ability to induce inflammation in pulmonary epithelial cells. To comprehend the potential role of T. tenax in pneumonia, it is crucial to elucidate the relationship between the parasite and the disease. We investigated the clinical factors associated with T. tenax infection in patients with pneumonia. Employing nested polymerase chain reactions, we amplified nucleic acids from BALF and analyzed the relationships between T. tenax and various clinical factors. Our data revealed a significant association between T. tenax and bacterial infections, high pneumonia severity index (PSI) scores, nasogastric tube feeding, and pulmonary complications. Logistic regression analyses also showed strong associations between T. tenax and these clinical factors in pneumonia patients. These findings suggest that T. tenax infection in pneumonia is accompanied by bacterial infection and severe clinical manifestations.

Abstract
Porphyromonas endodontalis is an oral anaerobic bacterium associated with periodontitis but seldomly been detected in other diseases. Only one case of respiratory disease caused by Porphyromonas endodontalis, pyopneumothorax, has been reported so far. A 53-year-old man with refractory periodontitis was admitted due to an indeterminate lung space-occupying lesion. Following mNGS analysis of the liquefaction necrotic area and solid component of the lesion through biopsy, Porphyromonas endodontalis and Parvimonas micra were detected. Therefore, the patient was diagnosed with an aspiration lung abscess and discharged after receiving effective antibacterial treatment. The Chest computed tomography (CT) scan revealed a remarkable improvement during outpatient follow-up. In this study, we applied mNGS to diagnose a case of lung abscess attributed to an uncommon bacterium successfully, suggesting that when patients complicated with periodontal diseases and clinical respiratory symptoms, the possibility of inhalation disease caused by oral pathogens should be considered.

Successful Interventional Treatment of Pyopneumothorax Caused by Streptococcus constellatus Associated with Hashimoto's Thyroiditis: A Case Report and Literature Review. Infect Drug Resist 2023; 16:7581-7586. [PMID: 38107434 PMCID: PMC10724682 DOI: 10.2147/idr.s435645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 11/15/2023] [Indexed: 12/19/2023] Open
Abstract
Background Streptococcus constellatus rarely causes pyopneumothorax, which is a serious state and requires a surgery. However, not every patient can tolerate surgery and individualized solutions are needed. Furthermore, many known situations are risk factors of S. constellatus infection, but S. constellatus pyopneumothorax associated with Hashimoto's thyroiditis has not been reported. Case Presentation We present the case of a 74-year-old male with multiple encapsulated pyopneumothorax caused by S. constellatus. Given his respiratory failure, we provided two-stage percutaneous right empyema radiography for catheter drainage in the radiology interventional department instead of surgery. Moreover, an occult Hashimoto's thyroiditis was discovered in the patient, which was possibly associated with S. constellatus pyopneumothorax. Levothyroxine was administered to improve his situation. Conclusion To our knowledge, it is the first case described in this context. We provided an alternative treatment for S. constellatus encapsulated pyopneumothorax in patient who might not tolerate surgery. We also revealed the possible relationship between S. constellatus pyopneumothorax and Hashimoto's thyroiditis.
