Chronic bronchitis in childhood: what is it?
Insights
Childhood chronic bronchitis (CB) diagnosis often differs from adult criteria, with physicians using varied definitions. Many cases show significant overlap with asthma in causes, symptoms, and treatment, making differentiation difficult.
Area of Science:
- Pediatric Pulmonology
- Respiratory Medicine
- Clinical Practice Research
Background:
- Over 2.5 million children are affected by chronic bronchitis (CB) nationally.
- Understanding childhood CB characteristics and adult form similarities is limited.
- Current diagnostic and treatment approaches for pediatric CB require clarification.
Purpose of the Study:
- To investigate how pediatricians and family physicians diagnose childhood chronic bronchitis (CB).
- To evaluate current treatment strategies for CB in children.
- To compare childhood CB diagnostic criteria with established adult epidemiological criteria.
Main Methods:
- A survey was distributed to 103 pediatricians and family physicians in Tucson.
- Physicians were questioned on diagnostic criteria and common treatments for childhood CB.
- Response rate for the survey was 45%.
Main Results:
- Diagnostic criteria for CB varied among physicians; a chronic productive cough was key for only 55% of pediatricians but 74% of family physicians.
- Recurrent cough episodes (over two weeks) were important for 86% of pediatricians.
- Allergies were frequently cited as a cause, and bronchodilators were common treatments, suggesting overlap with asthma.
Conclusions:
- Pediatric CB diagnosis frequently deviates from standard adult epidemiological criteria.
- Childhood CB exhibits substantial overlap with asthma in etiology, pathophysiology, and treatment.
- Distinguishing between asthma and CB in children presents significant challenges.
Abstract:
According to national statistics, over 2.5 million children have chronic bronchitis (CB). The characteristics of childhood CB and the similarities to the adult form are unknown. To determine the conditions under which childhood CB is diagnosed and to evaluate how it is treated, questionnaires were sent to 103 pediatricians and family physicians to Tucson. Forty-five percent responded. A chronic productive cough lasting at least three months a year was important for the diagnosis of CB for only 55% of pediatricians and 74% of family physicians. Recurrent episodes of cough lasting more than two weeks were important for the diagnosis of CB for 86% pediatricians. Sputum production was important for the diagnosis for about 50% of physicians felt that allergies were a common cause of childhood CB and bronchodilators were commonly used to treat CB. The results of this survey suggest that: (1) the diagnosis of CB in childhood is not often based on the usual epidemiologic criteria used for diagnosing CB in adults; and (2) CB in childhood may have considerable overlap with asthma with respect to etiology, pathophysiology, and treatment. In fact, for many children, there appear to be few ways to distinguish asthma from CB.
