Baseline characteristics by cohort

Baseline characteristics by cohort
Measure
Sildenafil
n=7 Participants
Male and female subjects between the ages of 6 months and 10 years, weighing at least 8 kg and had been given a diagnosis of a lymphatic malformation of at least 3 cm based on clinical and radiologic criteria. Macrocystic, microcystic, or mixed lymphatic malformations involving any location on the body were included. Lymphatic malformations associated with an incomplete response to previous treatments, a risk of functional or aesthetic impairment, or local complications were included.

Timeframe: Baseline, 20 weeks

Participants were given sildenafil for 20 weeks. Participants weighing more than 20 kg were given 20 mg 3 times daily (60 mg/day). Participants weighing between 8 kg and 20 kg were given 10 mg 3 times daily (30 mg/day).

Outcome measures

Measure
Sildenafil
n=7 Participants
The primary outcome was the effect of sildenafil on lymphatic malformation volume. Response to sildenafil was characterized by any decrease in lymphatic malformation volume. Lymphatic malformations volumes were assessed blindly by MRI volume segmentation analysis at baseline and after 20 weeks of sildenafil. 4 subjects had a lymphatic malformation volume decrease.

Measure
Sildenafil
n=7 participants at risk
Adverse events reported while one sildenafil were minimal. All subjects tolerated the prescribed medication dose. One subject developed an upper respiratory tract infection and experienced temporary hearing loss due to fluid accumulation. This was resolved completely and she experienced no further hearing loss while on sildenafil. Four parents requested to have the child continue sildenafil after study completion.
