A father who was infected with Hepatitis C as a toddler after being given tainted blood medication broke down in tears today as he told the inquiry into the scandal of the 'shame he felt' carrying the disease. Matthew James Johnson told the ongoing Blood Inquiry in London his life had been 'completely dismantled' over something that could have been stopped and that the didn't want anyone to go through the 'horror's his family had been through. The 38-year-old also revealed that he has been left at risk of contracting a neurological disease, and tearfully spoke of his fear that his own young son could see him 'waste away'. Matthew was diagnosed with Haemophila B when he was just one, after his parents had taken him to the hospital after he fell out of his cot, his front two teeth coming through his top lip Matthew was diagnosed with Haemophila B when he was just one, after his parents had taken him to the hospital after he fell out of his cot, his front two teeth coming through his top lip. The condition meant that Matthew's blood did not clot properly and he was treated on a regular basis with factor products, before being treated as a 'guinea pig' with different medications. Today Matthew says the treatment led him to having contracted Hepatitis C and further problems which were only addressed two years ago, when the Haemophilia society released a statement on their website saying there had been two sporadic cases of CJD (a rare blood disease) and Haemophilia. Holding back the tears, he said: 'That sent me over the edge. Because at that point I had a little boy who was my life and I didn't want him to see his Dad waste away'. He said that everyday he lives with the fear that he may hay CDJ and that he is scared of 'falling of balance'. 'You think it's starting and it's horrible. I am anti depressant dependent, I can't come off them and its had a huge impact on my life. A letter which was sent out to Matthew stated that there was no information available for products used on patients with Haemophilia During the inquiry, Matthew highlighted how he felt guilt for his parents and family 'Also for my parents, it's not been easy'. The inquiry is chaired by former High Court judge Sir Brian Langstaff who has promised to put people at the heart of the probe. During the inquiry, Matthew highlighted how he felt guilt for his parents and family. 'I have an amazing set of parents but what I have seen it do to them. I feel guilt – they have been beset by their own problems. 'I can't imagine what my parents went through. The CJD thing was very difficult for me and when the society posted it on their site it wasn't the most thought out thing to do.' Matthew was diagnosed with Hep C at a young age and said that growing up with the condition, you are told my medical professionals that 'it's not a big deal'. Medical records were presented to the inquiry showing the different treatment Matthew had The letter above, which confirms that Matthew did have Hep C, and that they had found it in a blood sample 'I thought why me? But since then I have lost people close to our family that have been infected I feel why am I still deserving to be here?' He said that many people who are aware of his condition often perceive that he is a drug user. 'Back twenty/ thirty years ago people weren't so forgiving. 'The evidence I am giving is true – it's all been really painful and I want to thank my family for everything they have done for me. In October 2004 it was revealed that Matthew had been exposed to two batches of the contaminated material 'I hope some good comes of this and I hope the people who are accountable are held to account. I don't want another to die. We are a rich nation, people should not be put behind profit for pharmaceutical profit. 'It breaks my heart, I'm lucky I'm here and I cleared Hep C. There are people who have lost people they love.' As a youngster Matthew had been treated at a centre in Oxford , and for the first few years of his life, visits to the centre were a weekly occurrence. He was given factor treatment, which was common for someone with his condition. Patients were told they could find out more about whether or not they had been infected, which Matthew chose to do Patients were written to regarding the donors who had provided plasma for clot factors There had been a discussion between doctors and his parents to prevent bleeding to have prophylaxis to stop you becoming sick in later life. Matthew was treated at home by his parents and with every new medication, he says the family were made aware of the risks, however, they were told that the products that infected him had been groundbreaking. 'We were told they were clean and that I had to have them to prevent arthiritis.' 'There was a discussion about Hep C and the nature of the risks but were just told it would be nothing more than a cold. 'I think I was exposed to contaminated concentrates in 1981-1984 because the treatment improved 1985-1985, but the exact date can't be proved.' In his witness statement he said he may have been a PUP (previously untreated patient'. 'I was very very young – if my parents were told the risk then they wouldn't have given me the factor that caused so much damaged. 'I've seen record which show various people knew the risk from 1979 and I was still given it. I'd like the people to be held accountable for what they have put me and my family through 'Hand on my heart, my parents would not have given me that if they knew the risks.' Matthews parents were told he had been infected with Hep C, and Matthew revealed that he didn't know if his parents had given consent for him to even by tested for the disease. 'Nothing suggests they were asked to give consent – took four requests to get this information and I only got it when my legal team intervened. 'I was there every other week so my parents could have been told – I went there 15 times between two years.' Matthew said there had been a delay on the information getting through to his parents and added that he feels angry for them. 'I fell angry, upset, more so for my parents, they have a massive sense of guilt on them' 'That delay causes me anger, for two obvious reasons, one that I wasn't being treated properly and that there was a risk of others being infected by me 'Mum used to do my injections – what if she would have pricked herself? That risk was already there and I had that sense of shame. What if I would have affected my mum or sisters'. In 1994 there had been a discussion about Matthew receiving treatments which contained higher concentrates , but there was a delay in product. When he wrote off for a risk assessment he was told he had been 'exposed to two batches between 1995 and 1997'. Mr Johnson added: 'I got two hits, so from that obviously it caused serious concern and alarm. Matthew said he found out that Welsh people could get treatment at any age, and his parent inquired about moving there to receive the treatment. 'My parents asked if they moved to Wales then would I receive the treatment and they were told that if we did that we wouldn't get it, as 'that's not how it works'. His parents received a letter of the risks of CJD which they hid from him and when he went back to the centre he was informed. 'When I got the letter I was angry – it could have been prevented – all completely preventable, I've seen people that have died. It's massive mental hit on me.' The centre said risk was minimal - I automatically though I was going to die. Growing up I never had an issue with liver issues and things like that, but with this I had seen people lose all their functions and I couldn't have that for me or my parents – I was convinced I was going to die.' At the end of the trial, Matthew was commended for his bravery and added: 'I don't want people to go through what we have gone through. I know the guilt they feel and the horror they feel and I don't want them to go through that.' The inquiry continues. All rights reserved for this news site dailymail and under his responsibility
