THE father of twin boys infected with HIV and hepatitis C from contaminated blood has told of his horror at discovering one of his sons had his brain removed for testing after his death, without the family’s knowledge or permission.

Condemning the “shameful history of this heartbreaking nightmare”, the boys’ father gave evidence to the Infected Blood Inquiry about how his twins were given the illnesses as young children, which led to the death of one.

The man, who spoke under the condition of anonymity, explained how the boys were diagnosed with a severe form of the blood condition haemophilia at just 11 months old, which required regular treatment using blood products.

In 1985, when the boys were 10, they were diagnosed with HIV, followed by hepatitis C, despite the family having not been told they were at risk or that they were being tested for the diseases.

The angry father, referred to as Mr AB, described how he felt the twins were “treated like lab rats”, and were given different medication without explanation.

When one of the boys became severely ill, he was admitted to hospitals in Glasgow, where he eventually died in 1992. But in the hours before the 17-year-old’s death, Mr AB revealed that two doctors had questioned him about funeral plans and possibly carrying out post-mortem tests – he said no.

However, during a chance encounter with one of the doctors six months after his son died, he was told that his son had his scalp and skull opened and his brain removed to discover the cause of death.

It emerged that measles had infected the boy’s brain, and his father said he was told “if only we had known that, we could have done more” by the doctor.

The inquiry, chaired by Sir Brian Langstaff, was hearing evidence on the final day of its Scottish stage in Edinburgh.

The hearings are scheduled to continue in Cardiff from July 23.
