Prognostic Factors for Long-term Aesthetic Outcome of Infantile Haemangioma Treated with Beta-blockers

Parents of infants treated with beta-blockers for infantile haemangioma are often concerned about the long-term aesthetic outcome. This cross-sectional study assessed the influence on the long-term aesthetic outcome of characteristics of the infantile haemangioma, the beta-blocker treatment, and the infant. The study included 103 children aged 6-12 years, treated with beta-blockers (propranolol or atenolol) for infantile haemangioma during infancy (age at treatment initiation ≤1 year) for ≥6 months. Dermatologists and parents scored the Patient Observer Scar Assessment Scale, and the child scored a visual analogue scale. Dermatologists identified whether telangiectasia, fibrofatty tissue, and atrophic scar tissue were present. The long-term aesthetic outcome of infantile haemangioma was judged more negatively by dermatologists and parents in case of a superficial component, ulceration, older age at treatment initiation, higher cumulative dose, and/or shorter follow-up time. According to children, infantile haemangioma located on the head had better aesthetic outcome than infantile haemangioma located elsewhere. Close monitoring, particularly of infantile haemangioma with a superficial component, is essential for early initiation of treatment, and to prevent or treat ulceration. These outcome data can support parental counselling and guide treatment strategy.</p

Mental Health of School-Aged Children Treated with Propranolol or Atenolol for Infantile Hemangioma and Their Parents

Background: Infants with infantile hemangioma (IH) have been effectively treated with propranolol or atenolol. Concerns were raised about the mental health of these The trial registration: Netherlands Trial Register Trial NL7703.children at school age, due to central nervous system effects of propranolol and visible nature of IH. Objective: This study aimed to compare the mental health at school age of children treated with propranolol to children treated with atenolol for IHs and their parents. Methods: This two-centered cross sectional study included children aged =6 years and treated with either propranolol or atenolol for IH during infancy. Children’s outcomes were performance-based affect recognition (Dutch version of the Developmental Neuropsychological Assessment-II [NEPSY-II-NL]), parent-reported emotional and behavioral functioning (Child Behavioral Checklist [CBCL]), and health-related quality of life (KIDSCREEN27). Parents’ outcome was parenting stress (Parenting Stress Questionnaire [OBVL]). Results: Data of 105 children (36 propranolol, 69 atenolol; 6.0–11.8 years) were analyzed. Mental health outcomes did not differ between both ß-blocker groups. Although overall functioning was in line with norms, children presented specific problems concerning affect recognition, parent-reported attention, and social quality of life. Parents showed increased physical symptoms, depressive symptoms, and parent-child relationship problems. Conclusion: No difference in mental health at school age was found between children treated with propranolol or atenolol for IH. Although few overall mental health problems were found, specific problems require follow-up. Follow-up of children should be directed toward affect recognition, attention, and social functioning in daily life. Problems reported by parents could be ameliorated by mental health support during and after their infant’s ß-blocker treatment.</p

Early MRI diagnosis of Sturge Weber Syndrome type 1 in infants

Background: Patients with Sturge-Weber syndrome type 1 (SWS1) have a port-wine birthmark (PWB) as cutaneous hallmark. Up to 35% of neonates with a high risk PWB develop SWS1. Clinical manifestations are severe and often progressive. Especially early onset seizures are associated with worse neurocognitive outcome. Identification of pre-symptomatic SWS1 patients is hampered because brain MRI in the first months of life does not always show the for SWS1 characteristic leptomeningeal capillary malformation (LMC). Objectives: Identification of sensitive and specific MRI predictors for early SWS1 diagnosis. Methods: In this retrospective single centre study, we included 24 SWS1 patients and 20 controls. We studied specificity and sensitivity for SWS1 diagnosis of LMC and indirect MRI signs such as choroid plexus (CP) size and thickness, abnormal white matter signal, lobar cerebral atrophy, ischemia and cortical calcifications. Results: In SWS1 patients CP thickness and CP thickness ratio on non-contrast brain MRI was significantly increased. The optimal cut-off value of 5.6 mm on the affected side corresponded with a sensitivity of 91.7% and a specificity of 100% for confirmation of SWS1 diagnosis. In 21% of children aged ≤3 months with a later confirmed SWS1 diagnosis, LMC on initial MRI could not be discerned but CP thickness ≥5.6 mm on the affected side confirmed SWS1 diagnosis. Conclusions: In this study, CP size ratio and thickness were found to be sensitive and specific signs additional to earlier described criteria to support SWS1 diagnosis in neonates and infants which need to be confirmed in other series

Patients with Congenital Low-Flow Vascular Malformation Treated with Low Dose Sirolimus

Introduction: Patients with congenital vascular malformations often suffer from an impaired quality of life (QoL) because of pain and functional disabilities. Previous studies have shown that the mTOR inhibitor sirolimus can reduce complaints and improve QoL in some patients. High target levels of sirolimus of 10–15 ng/ml were well tolerated; however, in a relative high percentage of patients sirolimus caused serious adverse events (AEs). Methods: A case series of 12 patients with therapy-resistant low-flow vascular malformations was treated with sirolimus, using low target levels of 4–10 ng/ml. Efficacy of sirolimus was evaluated in regard to pain symptoms using the visual analogue scale/numeric rating scale and patients reported QoL. To rule out a placebo effect of sirolimus, sirolimus was stopped after a certain time point and reintroduced as soon as complaints returned. Adverse events were closely monitored and graded using the Common Terminology Criteria for Adverse Events (CTCAE) grading. Results: An improvement in symptoms was seen in 92% (n = 11/12) of patients. In nine patients pain complaints returned. Seven out of nine of them (78%) again experienced a reduction of symptoms after restarting sirolimus treatment. Despite low target levels, these response rates are comparable to those found in the literature using higher target levels of sirolimus. However, significantly less serious AEs were observed with low dose sirolimus, suggesting low dose sirolimus might be safer. Unfortunately, young adolescent female patients developed serious menstrual disturbances during treatment with low dose sirolimus. We describe this adverse event for the first time in patients with congenital vascular malformations and this might be specifically related to low dose sirolimus. Conclusions: Low dose sirolimus showed a high efficacy in patients with therapy-resistant and low-flow malformation, with a lower incidence of serious adverse events. At the same time a new adverse event, namely menstrual cycle disturbance, was observed in young adolescents, indicating the need for caution when sirolimus is given. This is extremely relevant to patients with low-flow vascular malformation, who are likely to require lifelong treatment for their condition

Clinical differences in sirolimus treatment with low target levels between children and adults with vascular malformations – A nationwide trial

The clinical presentation of patients with slow-flow vascular malformations is very heterogeneous. High clinical burden and subsequent reduced health-related quality of life is something they have in common. There is an unmet medical need for these patients for whom regular treatments like surgery and embolization are either insufficient or technically impossible. Sirolimus has been reported to be effective and overall well-tolerated in most patients. However, the main limitation of sirolimus is the reported high toxicity, especially when target levels of 10–15 ng/mL are being used. We report the results of a phase IIB single-arm open-label clinical trial consisting of 68 (67 in the challenge phase and 68 in the rechallenge phase) evaluable patients (children n = 33 and adults n = 35) demonstrating that treatment with low sirolimus target levels (4–10 ng/mL) is effective in 79.1% of the patients. When sirolimus treatment was stopped, the majority of patients experienced a recurrence of symptoms, supporting prolonged or even lifelong treatment requirement. Adults experienced a higher baseline pain score compared with children, having an estimated marginal mean of 6.2 versus 4.1, p 0.05) compared with adults. Additionally, response rates were higher in children compared with adults (93.8% vs. 65.7%, p < 0.05), and children responded faster (28 vs. 91 days, p < 0.05). These results suggest benefits of sirolimus in patients with slow-flow vascular malformations and support its initiation as young as possible
