简要总结
The goal of this clinical trial is to evaluate the efficacy of the product in developing immune reinforcement that results in decreased susceptibility to respiratory infections of viral origin in children aged 3 to 10 years with a number of respiratory tract infectious events in the previous year greater than 4. The main questions it aims to answer are:
- Has the number of infectious events been reduced from last year?
- Does the severity of symptoms decrease with the use of the product?
Participants will be treated for 4 months. Treatment efficacy will be evaluated by:
- 2 scheduled visits with the investigating pediatrician (T0 - enrollment and start of treatment; T1- end of treatment).
- Verification of progress during the study by scheduled telephone meetings.
- The use of a diary where the patient or parent/caregiver will report all events (even mild) affecting the respiratory tract, taking care to fully complete the Wisconsin Upper Respiratory Symptom Survey for kids (WURSS-k) questionnaire.
详细描述
The immune system is a complex network consisting of organs, tissues, cells and the substances they produce. It has the function of protecting the body from external agents (including infectious agents) by activating three different types of response: the innate response, the adaptive response, and the mechanical or chemical response. The innate and adaptive response are activated together, one modulating the other. The innate or natural response represents a first line of defense. The adaptive or specific response is a slower but more powerful and targeted defensive response and enables the creation of immunological memory.
In the pediatric setting in the early months, and in the later first years of life, where the "immunological memory" has not yet strengthened, infectious events such as fever, flu, colds, throat discomfort, cough, respiratory infections, sore throat, various respiratory tract ailments, gastrointestinal diseases or related only to the intestinal tract occur frequently. It will take time for it to strengthen, and for the little one to be immune to a bacterial infection, but there are remedies to help. A healthy lifestyle, physical activity and a balanced diet that allows the right amount of protein, vitamins and minerals can strengthen the immune system. In some cases, where healthy diet and lifestyle needed support, the use of natural substances with immune-stimulating action proves useful.
The tested product is a dietary supplement specifically designed to modulate immune defenses in children. It contains the innovative IMMUREMEDY®-B complex and Lactobacillus rhamnosus CRL1505. Zinc and vitamins B6, B12, C, and D contribute to normal immune system function. Elderberry and acerola support the body's natural defenses. Lactobacillus rhamnosus CRL1505 is a probiotic that promotes the balance of the flora intestinal flora. Several clinical studies have shown that it can reduce the incidence of pediatric infections, including respiratory tract infections.
The goal of this clinical trial is to evaluate the efficacy of the product in developing immune reinforcement that results in decreased susceptibility to respiratory infections of viral origin in children aged 3 to 10 years with a number of respiratory tract infectious events in the previous year greater than 4.
Treatment consists of taking one single-dose bottle daily for a total of 4 months as follows:

结局指标
主要结局
Evaluation of the reduction in the severity of symptoms related to Acute Respiratory Tract Infections
时间窗: For each infectious event, it should be filled in on the first day of symptoms, on the third day of symptoms, and if symptoms persist, it should also be filled in on the seventh day of symptoms.
Evaluation of the reduction of illness-specific symptoms during an ARI by means of validated 15-items questionnaire (WURSS-k)
次要结局
- Evaluation of the reduction in the number of Acute Respiratory Tract Infections(T0 (first visit), T1 (4 months later - end of treatment))
