Patient Characteristics Associated with Concurrent Klebsiella pneumoniae Infection and Severe Pulmonary Tuberculosis.

Background: This study aims to investigate the clinical characteristics associated with concurrent Klebsiella pneu-moniae (K. pneumoniae) infection in hospitalized patients with severe pulmonary tuberculosis.

Methods: A retrospective study was conducted on hospitalized severe pulmonary tuberculosis patients between January 2019 and December 2020.

Concurrent severe pulmonary tuberculosis with Evans syndrome: a case report with literature review.

Background: Tuberculosis is a bacterial infection involving multiple organs and systems. Its hematological presentation mainly includes anemia and leukocytosis. Evans syndrome is a rare autoimmune disease characterized by autoimmune hemolytic anemia, immune thrombocytopenia, and neutropenia, with positive results for the direct Coombs test and platelet antibodies.

The Correlation between 25-Hydroxyvitamin D3 and the Severity and Short-Term Prognosis of Pulmonary Tuberculosis.

Background: Pulmonary tuberculosis is a chronic infectious disease caused by mycobacterium tuberculosis in the lungs. The present study aims to investigate the correlation between serum 25-hydroxyvitamin D3 (25-VD3) and the severity and short-term prognosis of tuberculosis.

Methods: The clinical data of 261 pulmonary tuberculosis patients, who were admitted to the Tuberculosis Diagnosis and Treatment Center of our hospital from January 1, 2017 to December 31, 2020, was retrospectively collected.

Misdiagnosed tuberculosis being corrected as Nocardia farcinica infection by metagenomic sequencing: a case report.

Background: Disseminated nocardiosis is liable to be misdiagnosed owing to the non-specific clinical manifestations and laboratory/imaging findings. Metagenomic next-generation sequencing (mNGS) is a culture-independent and rapid method for direct identification of all microorganisms in clinical specimens.

Case Presentation: A 72-year-old man was admitted to our hospital on February 20, 2019 with a history of recurrent cough, expectoration, fever, and diarrhea since 1 month, and unconsciousness since 1 week.

Sepsis secondary to multifocal Enterococcus faecium infection: A case report.

Introduction: Nosocomial Enterococcus faecium (E faecium) infections are common among immunocompromised patients; however, sepsis caused by E faecium is rarely encountered in the clinical setting.

Patient Concerns: A 69-year-old woman with a previous history of tuberculosis (TB), developed symptoms of recurrent fever, paroxysmal cough, and exertional dyspnea for over 2 months before she presented to the hospital.

Diagnosis: The patient was initially misdiagnosed with recurrent TB, and did not respond to anti-TB therapy.
