Turns out, children who take paracetamol during their first two years of life may be at a higher risk of developing asthma by the age of 18, especially if they have a particular genetic makeup.
According to a new research presented at the European Respiratory Society International Congress in 2018, the link between paracetamol use and asthma seemed strongest in those who had a particular variant of the glutathione S-transferase (GST) gene, GSTP1.
However, study author, Xin Dai, warned that the research showed only that there was an association between paracetamol and asthma, not that paracetamol caused the condition. She also found that another GST gene variant, GSTM1, was linked with reduced lung function.
GST genes contain the instructions for making enzymes that use an antioxidant called glutathione to mop up the effects of exposure to toxins in the body and the lungs. This mechanism helps to prevent damage to cells and inflammation.
“Paracetamol, on the other hand, consumes glutathione, reducing the body’s capacity to deal with toxic exposure. We hypothesized that people who did not have full GST enzyme activity because of common genetic variations or deletions may be more susceptible to adverse effects on the lungs from paracetamol use,” explained Dai.
Dai and her colleagues investigated their hypothesis in 620 children who had been followed from birth to 18 years old as part of the Melbourne Atopy Cohort Study.
The children had been recruited to the study before they were born because they were considered to be potentially at high risk of developing an allergy-related disease. They had at least one family member (mother, father or sibling) with a self-reported allergic disease (asthma, eczema, hay fever or a severe food allergy).
