Summary
Persistent fever in pulmonary tuberculosis patients despite chemotherapy may indicate concurrent septicemia. Blood cultures are crucial for identifying bacterial infections in these cases, even without leukocytosis.
Area of Science:
- Infectious Diseases
- Pulmonary Medicine
- Microbiology
Background:
- Pulmonary tuberculosis (TB) management typically involves chemotherapy.
- Fever is a common symptom of active TB.
- Chemotherapy aims to resolve symptoms, including fever.
Purpose of the Study:
- To investigate the cause of persistent fever in patients with pulmonary tuberculosis undergoing chemotherapy.
- To determine the prevalence and types of concomitant septicemia in this patient group.
- To assess the diagnostic value of blood cultures in febrile TB patients unresponsive to treatment.
Main Methods:
- Retrospective analysis of ten patients with bacteriologically confirmed pulmonary tuberculosis and persistent fever.
- Review of blood culture results for bacterial identification (Gram-positive and Gram-negative).
- Correlation of blood culture findings with sputum and urine cultures, and assessment of leukocytosis and radiographic signs of superinfection.
Main Results:
- Fever remained unchanged by chemotherapy in all ten patients.
- Blood cultures were positive in all ten patients: six with Gram-positive and four with Gram-negative organisms.
- Concordant organisms were found in sputum and blood in six patients, and in urine and blood in two patients.
- Leukocytosis and radiographic evidence of superinfection were absent.
Conclusions:
- Persistent fever in pulmonary tuberculosis patients treated with chemotherapy warrants investigation for concomitant septicemia.
- Blood cultures are essential for diagnosing concurrent bloodstream infections in febrile TB patients, irrespective of leukocytosis.
- Early identification of septicemia is critical for appropriate management and improved patient outcomes in complex TB cases.
