Symbiofilm Trial in Allergic Kids (SYMBIOFILM-TAK)
Study Details
Study Description
Brief Summary
Healsea® Children is a seawater-based nasal spray supplemented with a natural Symbiofilm® extract (0.02%) isolated from marine bacteria. Symbiofilm has antibiofilm activity against various bacterial pathogens involved in respiratory tract infections.Healsea® Children is indicated in the cleaning and moistening of nasal mucosa during common cold and rhinitis for children above 6 years.
This non interventional post-market clinical investigation aimed to confirm the benefit of Healsea® Children in real life setting in children with perennial allergy who are more prone to common cold.

Detailed Description
Healsea® Children is a seawater-based nasal spray supplemented with a natural Symbiofilm® extract (0.02%) isolated from marine bacteria. Symbiofilm® is an exopolymeric composition with emulsifying properties, in vitro antibiofilm activity and detachment properties against various bacterial pathogens involved in respiratory tract infections. Symbiofilm® has no bacteriostatic nor bactericidal activities. Healsea® Children is indicated in the cleaning and moistening of nasal mucosa during common cold and rhinitis.
The common cold is an acute viral infection of the upper respiratory tract, involving, to variable degrees, sneezing, nasal congestion and discharge (rhinorrhea), sore throat, cough, low-grade fever, headache, and malaise (1). It can be caused by members of several families of viruses; the most common are rhinoviruses. Acute viral rhinitis is generally self-limiting. In children where the illness is not self-limiting and extends beyond 7-10 days, many agree that a bacterial infection is likely (1). Bacterial over infections and progression to a chronic state are favoured by the formation of biofilms, which facilitate bacterial growth and persistence as well as reducing antibiotic efficacy (2-3).
Allergic diseases may play a particular role in promoting the respiratory infection recurrences (4). The physiological immune response is impaired in allergic subjects and allergic inflammation favours predisposition to respiratory infections. Subjects with allergic disorders may have functional defect of type 1 immune response that is relevant in fighting infections (5-6).
Allergic rhinitis (AR) may affect up to 40% of the paediatric population. Nasal symptoms are caused by exposure to an allergen to which a patient is sensitized.
AR is characterized by typical nasal symptoms and immunoglobulin E (IgE) -mediated inflammation. The allergic inflammatory process releases many cytokines and other proinflammatory proteins. Inflammation caused by nasal allergy leads to obstruction, fluid accumulation and acute disease. If these diseases are unsuccessfully treated, a chronic state of inflammation, obstruction, and infection develops that can cause mucosal damage and, ultimately, chronic disease (7).
For these reasons, the paediatric IgE-dependent allergic population that is more prone to common cold represents a suitable target for Healsea® Children (8-9).
During this prospective post-market clinical investigation, IgE-dependent allergic children with early symptoms of infectious rhinitis will be followed, children being treated with Healsea® Children on top of common cold conventional therapies or with conventional therapies only (excluded nasal irrigation).
Conventional therapies for non-complicated infectious rhinitis are symptomatic but are not without side effects. For example, decongestant use can increase blood pressure, antihistamine intake is associated with drowsiness.
Healsea® Children represents an interesting alternative that can not only improve acute infectious rhinitis symptomatology but could also limit the complication and progression to chronic state.
This non interventional post-market clinical investigation aimed to confirm the benefit of Healsea® Children in a real life setting in children with perennial allergy.

Outcome Measures
Primary Outcome Measures
- AUC (Area Under Curve) of the Wisconsin Upper Respiratory Symptoms Survey for Kids (WURSS-K) during the 10-day treatment period [Cumulative AUC of the WURSS score assessed from Day 1 to Day 10]
The WURSS-K will be assessed once daily, in the evening, considering the symptoms from the morning to the evening, from Day1 to Day10 (treatment period)
Secondary Outcome Measures
- Duration of common cold symptoms during the whole study: items 2 to 7 of WURSS-K [Number of days with cold symptoms during the intervention period (10-day treatment) and up to 30 days]
During the treatment period, the WURSS-K will be assessed once daily. After D10, the WURSS-K will be assessed once daily until the subject feels not sick for two consecutive days. Items 2 to 7 will be used to assess the duration of common cold symptoms in both groups.
- Respiratory complication requiring antibiotic prescription after the10-day treatment period [Number of subjects with respiratory complications during the 20-day follow-up period]
The number of subjects who develop respiratory complication requiring antibiotic prescription during a 20-day follow-up period after the treatment period will be assessed in both groups and compared
- Use of concomitant treatments [During the intervention, up to 30 days]
Frequency and number of days of use of concomitant treatments (conventional therapies) that may affect common cold symptoms (antibiotics, antipyretics, systemic or local mucolytics, decongestants, antitussives, systemic and topical corticosteroids) will be assessed in both groups and compared
- Spread of the common cold [During the intervention, up to 30 days]
The number of family members in close contact developing common cold symptoms after the patient all over the study period
- Reporting of incidents, undesirable expected side effects and adverse events [During the intervention, up to 30 days]
Assessment of adverse events, incidents, undesirable expected side effects during the intervention up to 30 in both groups
