Acetylsalicylic Acid Versus Placebo as an add-on Treatment to Local Non-steroidal Anti-inflammatory Drug for the Management of Thrombotic Episodes in Superficial Venous Malformations in Children Aged 6 to 17 Years. (ASPIRIN)
Acetylsalicylic Acid Versus Placebo as an add-on Treatment to Local Non-steroidal Anti-inflammatory Drug for the Management of Thrombotic Episodes in Superficial Venous Malformations in Children Aged 6 to 17 Years: a Controlled Randomised, Double-blind, Cross-over, Multicenter Trial
Superficial venous malformations (SVMs) are rare congenital anomalies that present as bluish masses. These masses may be focal, with limited skin involvement, or segmental, with more extensive involvement. They may be associated with syndromic conditions such as blue rubber nevus syndrome.
SVMs are characterised by a progressive worsening course, with repeated episodes of superficial venous thrombosis occurring. These episodes become more frequent over time, causing acute, intense and often highly debilitating pain.
To limit progression and in cases of functional impairment, long-term treatments may be offered. These include venous compression, targeted therapies such as mTOR inhibitors, and, where possible, surgical treatment or sclerotherapy.
However, the management of intra-SVM superficial venous thrombosis is not currently standardised, especially in the pediatric population. This study aims to evaluate the benefits of Acetylsalicylic acid (ASA) as an add-on treatment to local non-steroidal anti-inflammatory drug for the management of thrombotic episodes in superficial venous malformations in children aged 6 to 17 years.

Andet: ASA + local NSAID then placebo + local NSAIDs
This is a cross-over design.
Patients randomized in this sequence will receive ASA + local NSAIDs during their first flare-up, then placebo + local NSAIDs during their second flare-up (with a wash out period of two weeks).
|
AAS at anti-inflammatory doses administered orally for a minimum of 3 days and a maximum of 14 days.
Orally administered AAS is combined with the application of 1% diclofenac gel (NSAID) twice a day.
Placebo administered orally for a minimum of 3 days and a maximum of 14 days.
Oral placebo is combined with the application of 1% diclofenac gel (NSAID) twice a day.
Application of 1% diclofenac gel (NSAID) twice a day.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
The primary criterion is the total pain experienced during the episode, reflecting both intensity and duration.
Tidsramme: The first measurement is defined as the start of treatment following the onset of pain reported by the child. VAS data will be collected until the child has a VAS of 0 for two consecutive days, or for up to 14 days.
|
Pain intensity will be measured using a visual analog scale (VAS) ranging from 0 (no pain) to 10 (the most intense pain imaginable).
The child will self-assess their pain, with a parent's help if necessary, twice a day (morning and evening).
The area under the EVA-time curve is calculated using the trapezoidal method based on the available values over the duration of the episode.
