Contra-lateral paradoxical pleural effusion during antituberculous chemotherapy

Area of Science:

• Pulmonology
• Infectious Diseases
• Medical Case Reports

Background:

• Tuberculosis (TB) treatment involves chemotherapy to manage infection and associated complications.
• Pleural effusion, a common manifestation of TB, typically requires management alongside primary infection treatment.
• Paradoxical reactions, though rare, can occur during antimicrobial therapy, presenting as new or worsening symptoms.

Purpose of the Study:

• To report a case of paradoxical pleural effusion in a patient undergoing anti-tubercular chemotherapy.
• To highlight the diagnostic and management considerations for paradoxical reactions in TB patients.
• To discuss the clinical course and resolution of this unusual adverse event.

Main Methods:

• Case report of a 24-year-old male patient.
• Review of clinical presentation, diagnostic findings, and treatment course.
• Follow-up assessment of the paradoxical effusion.

Main Results:

• Development of left-sided pleural effusion 10 days after initiating anti-tubercular chemotherapy for right-sided disease.
• The new effusion was considered a paradoxical response to treatment.
• The pleural effusion resolved spontaneously on follow-up.

Conclusions:

• Paradoxical pleural effusion can occur as a rare complication of anti-tubercular chemotherapy.
• Close monitoring and clinical assessment are crucial for identifying and managing paradoxical reactions.
• Spontaneous resolution is possible, underscoring the need for careful observation rather than immediate intervention in select cases.
