Taking chemotherapy had an impact on his immune system
Initially, Ollie responded really well to chemotherapy treatment. But, as is commonly the case, taking chemotherapy had an impact on his immune system and his body’s ability to fight infection. During Ollie’s treatment, we were constantly checking to see if he was neutropenic. Neutropenic means that your neutrophils are low, and neutrophils are an important white blood cell that fight infection. The lower your neutrophil count, the more vulnerable you are to infectious diseases.
About five weeks into treatment, Ollie had not really eaten or drunk anything since treatment began. He was called back into hospital following abnormal blood results. When they redid his blood, it showed he was suffering from kidney failure. He was taken into a Paediatric Intensive Care Unit. He had a blocked heart valve as well as kidney failure. He stayed in the Paediatric Intensive Care Unit for 48 hours and then was transferred to isolation at the Royal Marsden.
