Area of Science:

  • Pulmonology
  • Internal Medicine
  • Clinical Diagnosis

Background:

  • Chronic cough is a prevalent condition affecting adults.
  • Diagnosis and treatment of chronic cough present significant clinical challenges.
  • Understanding the common etiologies is crucial for effective patient management.

Purpose of the Study:

  • To outline a diagnostic and therapeutic strategy for chronic cough.
  • To review the epidemiology, natural history, diagnosis, and treatment of chronic cough.
  • To provide a framework for managing patients with persistent cough.

Main Methods:

  • Literature search of MEDLINE from 1970-2000.
  • Selection of articles based on clinical relevance and study design.
  • Review of epidemiological cohort studies, case studies, and review articles.

Main Results:

  • Postnasal drip syndrome (PNDS), asthma, and gastroesophageal reflux disease (GERD) are the most common causes of chronic cough.
  • Chest radiography is recommended for initial investigation to exclude serious underlying conditions.
  • Diagnostic evaluations and therapeutic trials can identify PNDS, asthma, and GERD, often necessitating combination therapies.

Conclusions:

  • The primary causes of chronic cough are PNDS, asthma, GERD, or combinations thereof.
  • A systematic diagnostic and treatment approach is effective for the majority of chronic cough cases.
  • Integrated management strategies are key to resolving persistent cough.
