Asthma In Childhood Can Trigger COPD Later: Lancet

While smoking remains the biggest risk factor for chronic obstructive pulmonary disease (COPD), childhood illnesses such as asthma, bronchitis, pneumonia, allergic rhinitis and eczema also amplify the disease, say researchers.

Three-quarters of COPD cases have their origins in poor lung function pathways beginning in childhood, according to a cohort study published in The Lancet Respiratory Medicine journal.

A second study in the journal suggests that there could be a window of opportunity during childhood to reduce the risk of poor lung function in later life.

“These findings highlight the importance of preventing both early life adverse exposures that could lead to poorer lung growth and adult risk factors contributing to accelerated lung decline,” says Professor Shyamali Dharmage from School of Population and Global Health, The University of Melbourne, Australia. COPD is expected to be the third-largest cause of death globally by 2030. “It is important that we identify its key causes so that this burden can be reduced,” Dharmage added.

Reduction of maternal smoke exposure and personal smoking and promotion of immunisation are identified as public health targets to prevent poor lung function pathways.

“Doctors and patients with asthma should be made aware of the potential long-term implications of non-optimal asthma control throughout life, and this should be investigated in future research,” the study authors noted. In the first study, 2,438 participants from the Tasmanian Longitudinal Health Study (Australia) were tracked from childhood to the age of 53.

In the second study, 2,632 participants were tracked from birth to 24 years old and their lung function was measured. In the second study, the authors found that around three-quarters of infants aged one to six months with poor lung function improved throughout their childhood, indicating a window of opportunity to increase lung function and potentially reduce risk of COPD in later life.

Premature Birth Linked to Asthma

Children born very early - before 32 weeks gestation - had approximately three times the risk of developing asthma/wheezing disorders compared with babies born at term

Is your kid suffering from asthma and wheezing disorders? The reason may be the child’s premature birth, research showed.

The risk of developing these conditions increases as the degree of prematurity increases, the study showed.

The findings are based on a systematic review of 30 studies that investigated the association between pre-term birth and asthma/wheezing disorders among 1.5 million children.

Worldwide, more than 11 percent of babies are born premature.

Across the studies that ranged a time span from 1995 to present, 13.7 percent of premature babies developed asthma or wheezing disorders compared with 8.3 percent of babies born at term, representing a 70 percent increased risk.

“Children born very early – before 32 weeks gestation – had approximately three times the risk of developing asthma/wheezing disorders compared with babies born at term,” the study showed.

“As asthma is a chronic condition, our findings underscore the need to improve our understanding of the mechanisms underlying the association between preterm birth and asthma/wheezing disorders in order to develop preventive and therapeutic interventions,” said Aziz Sheikh of Brigham and Women’s Hospital (BWH) in Boston, US.
