Description of intervention(s) / exposure
This is an observational study aimed at comparing the effect of Propranolol, Captopril or Surgery on serum levels of components of the renin-angiotensin system (RAS) and other markers in patients with haemangioma. This will be achieved by measuring serum levels of Renin, ACE, Angiotensin II and Alpha-feto protein in participating infants and children at 4 time points. These time points are pre-treatment, after one month of treatment, after 6 months of treatment and after 1 year since start of treatment. Bloods will be taken by trained phlebotomists and/or paediatric doctors. The overall observation period is 12-14 months. This variation in overall observation period is determined by length of time on the propranolol - which in more problematic cases leads the treatment time to be up to 14 months of age - this length of time on treatment is determined by the medical doctors within the research team. In some instances, treatment is able to be stopped around 10-12 months of age, depending on the individual lesions response to treatment.

Comparator / control treatment
Propranolol (a medication for treating high blood pressure) is now used with better results. We have recently completed colelcting data from infant volunteers in a clinical trial that ran from 2010 to 2012 using Captopril treatment (another medication for treating blood pressure) for haemangioma. Our laboratory work shows a particular type of stem cell in haemangioma express components of the renin-angiotensin system (RAS) and other markers. Propranolol and Captopril target different parts of the RAS. As part of the Captopril study, blood samples were routinely taken before, during and after treatment for analysis. Those patients who undergo Propranolol treatment for haemangioma also have blood samples taken routinely, before and during treatment as part of their clinical management. There is also a sub-group of patients with haemangioma that are more effectively treated with surgery - and this sub group will be our control/comparator group. We would like to investigate the effect of these different treatments on the RAS and other markers with the hope of better understanding the biology and developing more novel and more effective and safer treatment for haemangioma.

Outcomes
Primary outcome [1] 288185 0
The primary outcome we are looking for is to compare the serial serum ACE, Angiotensin II, and Renin Levels in patients undergoing propranolol treatment for haemangioma, with those undergoing captopril and surgical treatment. These will be measured by venous blood analysis.
Timepoint [1] 288185 0
Serial measurements of RAS components at four time points. These include pre treatment, one month following start of treatment, 6 months following start of treatment and 12 months following start of treatment.
Secondary outcome [1] 299573 0
The secondary outcome we are looking for is to compare the serial serum alpha-feto protein (AFP) levels in patients undergoing propranolol treatment for haemangioma, with those undergoing captopril and surgical treatment. This will be measured by venous blood analysis. If AFP levels are outside of normal range, an abdominal ultrasound scan will be done to exclude liver abnormailities.
Timepoint [1] 299573 0
Serial measurements of AFP at four time points. These include pre treatment, one month following start of treatment, 6 months following start of treatment and 12 months following start of treatment.
