Summary

Bronchial hyperreactivity (BHR) is common in endobronchial tuberculosis (EBTB), often leading to misdiagnosis as asthma. Early BHR detection aids in differentiating EBTB from cough variant asthma.

Area of Science:

  • Pulmonology
  • Infectious Diseases
  • Respiratory Medicine

Context:

  • Endobronchial tuberculosis (EBTB) presents diagnostic challenges.
  • Symptoms like cough and wheezing can mimic asthma.
  • Accurate diagnosis is crucial for effective treatment.

Purpose:

  • To assess bronchial hyperreactivity (BHR) in EBTB patients.
  • To evaluate pulmonary function in EBTB.
  • To identify diagnostic clues for EBTB.

Summary:

  • A significant proportion (41.7%) of EBTB patients exhibit BHR.
  • EBTB patients often present with cough and shortness of breath, leading to potential misdiagnosis as asthma.
  • FEV(1%) was higher in EBTB patients with BHR, showing a negative correlation with BHR severity.

Impact:

  • Highlights BHR as a key feature in EBTB.
  • Emphasizes the need for differential diagnosis between EBTB and cough variant asthma.
  • Aids clinicians in recognizing EBTB, improving patient outcomes.
