Some medicinal syrups available in Indonesia contained ingredients linked to fatal acute kidney injury (AKI) in children, according to the country's health minister, as the country investigates a rise in cases and 99 child deaths this year.

Indonesia has temporarily banned the sale of all syrup-based medications and is closely investigating paracetamol syrups used locally to treat child high fever that contain diethylene glycol and ethylene glycol.

The government of Gambia is also investigating child AKI deaths linked to paracetamol syrups following 70 deaths there. Maiden Pharmaceuticals Ltd, located in New Delhi, manufactured the syrups, which India said it is investigating.

According to Indonesia's food and drug agency, such particular products are not available locally.

Ethylene glycol and diethylene glycol were detected in products found at the homes of some of the patients, health minister Budi Gunadi Sadikin said on Thursday, without specifying how many.

"Some syrups that were used by AKI child patients under five were proven to contain ethylene glycol and diethylene glycol that was not supposed to be there, or of very little amount," he said.

As of Thursday, Indonesia has identified 206 AKI child cases of which 99 were fatalities this year. Budi said the real number of cases could be higher than reported.

A health ministry spokesperson declined to say in how many child AKI patients the ingredients were detected, citing the ongoing investigation.
