New study finds correlation between asthma and kidney stones in children

Talking about the research carried out in Cleveland Clinic, Ohio, city paediatricians said asthma cases are rising among city kids, too. However, an India specific study is needed to verify the correlation


Did you know if your child is asthmatic, then he / she could be prone to kidney stones too?

A recent study published in PLoS One found that prevalence of kidney stones was fourfold greater in children with asthma as compared to children without it.

The researchers, who did the study at Cleveland Clinic in Ohio, observed that while kidney stones are rare in children, its incidence has been on a rise in the last few years.

With air quality in Mumbai getting worse by the day, the number of children suffering from asthma is on the rise in the city and the picture gets bleaker with this recent study.

Dr Prashant Rajput, Consultant Nephrologist and Transplant Physician at Global Hospitals, Mumbai, said though the PLoS One article is interesting, doctors are yet to find a similar association in Mumbai.

“There needs to be more screening and study needs to be undertaken to find if there is a similar link between asthma and kidney stones in children,” said Rajput.

Researchers found that prevalence of kidney stones was 0.08% in children’s population, but 0.31% in children with asthma and 0.53% among patients aged between 13 and 18. Cases of asthma in paediatric population was 6.8% compared with 26.7% in paediatric patients with kidney stones and 35% in paediatric stone patients younger than 12 years.

“Incidence of kidney stone in children is rare, unless there is a certain condition like renal tubular acidosis (a medical condition which involves an accumulation of acid in body due to failure of kidneys to appropriately acidify the urine). We need an Indian study to prove this new association between asthma and kidney stones in children,” said Dr Shrirang Bicchu, Nephrologist at Bombay Hospital.

As asthma cases have been on a rise in children, city paediatricians and chest physicians blame it on poor hygiene, increased intake of junk food and rise in construction work in city.

Dr Mukesh Sankhlecha, Paediatrician at Bombay Hospital said hygiene hypothesis can be one of the reasons behind rise in asthma among children.

“With our society becoming more advanced, lot of emphasis is given to hygiene. This leads to less exposure of child to infection, but makes the child more prone to allergies,” added Sankhlecha.
