The Effectiveness of a Dietary Supplement with Honey, Propolis, Pelargonium sidoides Extract, and Zinc in Children Affected by Acute Tonsillopharyngitis: An Open, Randomized, and Controlled Trial.

Physicians are currently finding products for pediatric respiratory diseases of viral etiology to reduce the inappropriate use of antibiotic therapy. This study evaluated PediaFlù (Pediatrica S.r.l.), a dietary supplement already on the market composed of honey, propolis, Pelargonium sidoides extract, and zinc (DSHPP), in children affected by acute tonsillopharyngitis (ATR). The open-label, randomized, and controlled study compared DSHPP + standard of care (SoC) versus SoC alone for six days. Children between 3 and 10 years with an ATR ≤ 48 h, a negative rapid test for beta-hemolytic Streptococcus, or a culture identification of nasal and/or pharyngeal exudates were included. A tonsillitis severity score (TSS) and the number of treatment failures (using ibuprofen or high-dose paracetamol as rescue medication) were the primary endpoints. DSHPP+ SoC showed better performance than SoC alone for TSS sub-scores: throat pain and erythema on day 6 (p < 0.001 and p < 0.05), swallowing (p < 0.01 on day 4), and TSS total score on days 4 and 6 (p < 0.05 and p < 0.001). Only one patient (SoC group) had treatment failure for ibuprofen administration. No adverse events were reported. DSHPP is an optimal adjuvant in the treatment of URTI and could potentially be useful in the daily clinical practice of paediatricians evaluating the correct antibiotic prescription.

Pilot, open-label, randomized controlled clinical trial evaluating 4 oral hygiene regimens using a manual toothbrush, toothpaste, and mouthwash.

In this prospective pilot study, 84 patients with a history of poor oral hygiene were enrolled in an open-label, interventional, randomized controlled clinical trial. The aim was to provide preliminary clinical data on a new line of oral hygiene products containing a prebiotic and a paraprobiotic based on Lactobacillus plantarum. The recruitment rate and patient satisfaction were analyzed to estimate resources for the future primary study, and descriptive data on rebalancing of the oral microbiota were collected. The population was divided into 5 groups based on the products assigned to the patients: 1, delicate mint toothpaste (n = 20); 2, mint toothpaste (n = 12); 3, mint mouthwash (n = 20); 4, delicate mint toothpaste, mint mouthwash, and an antimicrobial toothbrush (n = 20); and 5, continued use of their usual oral care products and routine (control group; n = 12). The study duration was 28 days. All patients tolerated the products well, and there were no adverse events. The recruitment capability and procedures allowed for a realistic estimation for the future main trial. The products did not cause any changes in tooth color. The participants in group 4, who completed the treatment consisting of delicate mint toothpaste, mint mouthwash, and an antimicrobial toothbrush, reported the greatest reduction in gingival sensitivity (P ≤ 0.000; Wilcoxon signed rank test). Analysis with the Wilcoxon signed rank test revealed that all products induced a statistically significant decrease in plaque (P ≤ 0.002) and a reduction in gingival sensitivity (delicate mint toothpaste, P ≤ 0.005; mint toothpaste, P ≤ 0.015; and mint mouthwash, P ≤ 0.015). All products were effective in stabilizing the oral microbiota. The tested products showed an optimal safety profile and a statistically significant efficacy in reducing gingival sensitivity and plaque. They also stabilized the biodiversity of the oral microbiota, making it less susceptible to microbial fluctuations than the control group. Trial registration: ClinicalTrials.gov (NCT05999175).

Assessment of the Feasibility of Objective Parameters as Primary End Points for Patients Affected by Knee Osteoarthritis: Protocol for a Pilot, Open Noncontrolled Trial (:SMILE:).

BACKGROUND: Osteoarthritis (OA) is a disabling condition that affects more than one-third of people older than 65 years. Currently, 80% of these patients report movement limitations, 20% are unable to perform major activities of daily living, and approximately 11% require personal care. In 2014, the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) recommended, as the first step in the pharmacological treatment of knee osteoarthritis, a background therapy with chronic symptomatic slow-acting osteoarthritic drugs such as glucosamine sulfate, chondroitin sulfate, and hyaluronic acid. The latter has been extensively evaluated in clinical trials as intra-articular and oral administration. Recent reviews have shown that studies on oral hyaluronic acid generally measure symptoms using only subjective parameters, such as visual analog scales or quality of life questionnaires. As a result, objective measures are lacking, and data validity is generally impaired. OBJECTIVE: The main goal of this pilot study with oral hyaluronic acid is to evaluate the feasibility of using objective tools as outcomes to evaluate improvements in knee mobility. We propose ultrasound and range of motion measurements with a goniometer that could objectively correlate changes in joint mobility with pain reduction, as assessed by the visual analog scale. The secondary objective is to collect data to estimate the time and budget for the main double-blind study randomized trial. These data may be quantitative (such as enrollment rate per month, number of screening failures, and new potential outcomes) and qualitative (such as site logistical issues, patient reluctance to enroll, and interpersonal difficulties for investigators). METHODS: This open-label pilot and feasibility study is conducted in an orthopedic clinic (Timisoara, Romania). The study includes male and female participants, aged 50-70 years, who have been diagnosed with symptomatic knee OA and have experienced mild joint discomfort for at least 6 months. Eight patients must be enrolled and treated with Syalox 300 Plus (River Pharma) for 8 weeks. It is a dietary supplement containing high-molecular-weight hyaluronic acid, which has already been marketed in several European countries. Assessments are made at the baseline and final visits. RESULTS: Recruitment and treatment of the 8 patients began on February 15, 2018, and was completed on May 25, 2018. Data analysis was planned to be completed by the end of 2018. The study was funded in February 2019. We expect the results to be published in a peer-reviewed clinical journal in the last quarter of 2024. CONCLUSIONS: The data from this pilot study will be used to assess the feasibility of a future randomized clinical trial in OA. In particular, the planned outcomes (eg, ultrasound and range of motion), safety, and quantitative and qualitative data must be evaluated to estimate in advance the time and budget required for the future main study. Finally, the pilot study should provide preliminary information on the efficacy of the investigational product.

POLARIS: efficacy and safety of a vaginal medical device in recurrent bacterial vaginosis-a multicenter, open-label, non-controlled, study with 10 months of follow-up.

OBJECTIVE: Recurrent bacterial vaginosis (RBV) after antibiotic treatment has relapse rates of 35% within 3 months and 60% within 12 months. A medical device containing polycarbophil, lauryl glucoside, and glycerides (PLGG) inhibits bacterial growth and has mucoadhesive properties. This study examined the efficacy of the device in women with RBV. METHODS: This post-market clinical follow-up study comprised two phases. The first phase was an interventional, open-label, non-controlled, multicenter study enrolling 56 women. The second phase was an observational 10-month follow-up without treatment. RESULTS: After three cycles of PLGG treatment, recurrence was identified in 8 of 54 evaluable patients (14.81%). A positive effect on lactobacilli in the vaginal secretions was observed in 26 of 39 patients (66.67%). Among 35 patients observed after stopping PLGG treatment, one case of RBV (2.86%) was observed after 4 months, and an additional six cases (17.14%) were observed after 10 ± 2 months. Therefore, no recurrence was evidenced in 12 subjects (34.28%) at the end of the study. CONCLUSION: The use of PLGG vaginal ovules in the treatment of BV reduces the rate of recurrence and apparently produces a positive effect on the vaginal microbiota.

The Effects of a Dietary Supplement (PediaFlù) Plus Standard of Care in Children With Acute Tonsillopharyngitis/Rhinopharyngitis: Protocol for a Randomized Controlled Trial.

BACKGROUND: A dietary supplement containing Pelargonium sidoides extract, propolis, zinc, and honey has been recently developed and proven to be an effective adjuvant in clinical practice for seasonal diseases and the treatment of respiratory tract disorders. OBJECTIVE: This trial aims to verify the efficacy of the tested dietary supplement in a pediatric population with acute tonsillopharyngitis/rhinopharyngitis (ATR). METHODS: The trial includes children aged between 3 and 10 years with ATR ≤48 h, a negative rapid test for beta-hemolytic streptococcus or culture identification of nasal and/or pharyngeal exudates, and SARS-CoV-2 infection. The dietary supplement tested is an oral solution already on the market based on Pelagon P-70 (equivalent to Pelargonium sidoides d.e. 133.3 mg/100 ml), propolis, zinc, and honey. The product is administered at 5 ml 3 times a day for 6 days for children younger than 6 years and 10 ml 3 times a day for 6 days for children older than 6 years. The study design is open label, randomized, and controlled, with the tested dietary supplement plus standard of care (SoC) versus SoC alone. Patients are enrolled from 3 sites in Romania. The change in Tonsillitis Severity Score and number of treatment failures (using ibuprofen or high-dose paracetamol as rescue medication) are the primary end points. Based on the Tonsillitis Severity Score and the 2-sample comparison of the means formula with a 5% significance level, 80% power, and a minimally clinically important difference of 2 (SD 3.85) points, 120 patients are required. To account for potential screening failures and dropouts, we need to screen a population of approximately 150 children. RESULTS: Patient enrollment began on June 3, 2021 (first patient's first visit), and ended on August 12, 2021 (last patient's last visit). The data collection period was from June 3, 2021, to September 16, 2021. The study was funded in February 2023. Data analysis is currently ongoing (April 2024). We expect the results to be published in a peer-reviewed clinical journal in the third quarter of 2024 and presented at scientific meetings in the last quarter of 2024. CONCLUSIONS: The data from this trial may help identify new adjuvant treatments for children with ATR when streptococcal infection is excluded by a negative rapid test, thereby avoiding unnecessary antibiotic administration.

Prevalence and burden of nausea and vomiting in pregnant women: Interim analysis of the PURITY survey.

OBJECTIVES: Nausea and vomiting in pregnancy is a common and invalidating condition in early pregnancy. However, no data are available on its prevalence in Italy. This survey aims to evaluate the prevalence and impact of nausea and vomiting during pregnancy on the quality of life of Italian women. STUDY DESIGN: The survey was performed in three Italian public University Hospitals in two distinct periods: a first interview took place between the 18th and 22nd week of pregnancy, using the Questionnaire for Pregnancy Period (14 questions regarding demographic data and 30 questions about nausea and vomiting in pregnancy, including Pregnancy-Unique Quantification of Emesis questionnaire), and a follow-up interview, by telephone call, took place immediately after giving birth and in any case within 14 days of delivery, using the Questionnaire for Post-Pregnancy (9 questions). Included women were Caucasian, in physiological pregnancy and between the 18th and 22nd week (time of morphological ultrasound), able to communicate adequately with the interviewer, understand the questionnaires and able to provide valid informed consent. Twin pregnancies and women who recurred to medically assisted procreation were excluded. This is an interim report on data collected from 232 of the planned 600 women. RESULTS: Mean age of the recruited subjects was 32.6 ± 4.6 years, with approximately 60% primiparous. The prevalence of nausea and vomiting in pregnancy in the sample examined was 65.5% overall (152 out of 232 subjects). Of these 152 women, 63 (41.4%) experienced only nausea, 6 (3.9%) only vomiting, and 83 (54.6%) reported both. Symptoms were reported to begin at 7.2 ± 2.7 weeks, lasted 10.2 ± 5.6 weeks, and persisted at the time of the interview in 32.2% of cases. Overall, over 50% of the women interviewed experienced a negative impact of nausea and vomiting in pregnancy on social relationships and work activity. CONCLUSIONS: A high prevalence of nausea and vomiting in pregnancy, 65.5% overall, was found in this interim analysis. These symptoms appeared capable of negatively influencing women quality of life. Screening procedures should be offered during pregnancy and measures that address nausea and vomiting in pregnancy impact warranted.

Performance and Safety of a New Medical Device (Polybactum) for Reducing the Recurrence Rate of Bacterial Vaginosis: Protocol for a Multicenter, Open-Label, Noncontrolled International Clinical Trial (POLARIS Study).

BACKGROUND: The medical literature has reported that recurrent bacterial vaginosis (RBV) has a relapse rate of 35% within 3 months and 60% within 12 months after antibiotic administration. Products that are able to provide a barrier effect against the biofilm produced by Gardnerella vaginalis could play a role in improving the results of bacterial vaginosis (BV) treatment. OBJECTIVE: This study aims to assess the performance and safety of a medical device (Polybactum) containing polycarbophil, lauryl glucoside, and glycerides (PLGG) for reducing the rate of recurrence of BV. METHODS: The study includes women who are aged above 18 years, are willing to provide signed informed consent, have a diagnosis of BV according to the Amsel criteria, and have been affected by at least 2 episodes of RBV in the last 12 months. The trial includes 2 phases. In the first phase (according to an open-label noncontrolled design), the treatment involving PLGG is administered for 3 cycles and is followed by a 1-month period of follow-up without treatment. In the second phase, a 9-month follow-up period is envisaged. Thus, for each patient, a 10-month follow-up period without treatment is planned. The study involves 5 centers (2 in Italy and 3 in Romania). We calculated a sample size of 44 pairs to achieve a power of 80% and a 1-sided significance of 5% for detecting a difference of 0.25 between marginal proportions, in comparison with the mean recurrence rate of BV reported in the medical literature. We estimated a potential dropout rate of 20%, and thus, we decided to enroll 55 patients (1-group chi-square test). RESULTS: The study received ethics approval in 2016 in Romania and 1 year later in Italy. Recruitment started in September 2016. An interim analysis was performed in 2019, and full study analysis results are expected in July 2023. CONCLUSIONS: The tested medical device involving PLGG could modify the mechanisms involved in the pathogenesis of BV and could improve microbiological parameters owing to the acidifying effect on vaginal pH. We believe that the findings of our study could be useful for other investigators who want to test different products against RBV using a standardized protocol and standardized procedures.

Polycarbophil vaginal moisturizing gel versus hyaluronic acid gel in women affected by vaginal dryness in late menopausal transition: A prospective randomized trial.

OBJECTIVES: During menopausal transition, women are frequently affected by vulvovaginal atrophy (VVA), due to the decline of estrogen levels. Resulting symptoms are itching, burning, dyspareunia, and vaginal dryness (reported in up to 85%). The aim of this trial was to verify if medical device polycarbophil vaginal (PCV) moisturizer gel is not less effective than hyaluronic acid (HA) gel in treating vaginal dryness. MATERIAL AND METHODS: This was a multicenter, open label, randomized, parallel group, comparative study with non-inferiority design. Female included were ≥45 to ≤55 years in the menopausal transition, with subjective dryness, any objective sign of VVA, pH > 5, and body mass index of ≥18.5 to ≤36 kg/m2. Subjects were randomized to 1 g of PCV gel twice a week for 30 days or 3 g of HA vaginal gel every 3 days for 30 days. RESULTS: 53 subjects (mean age 49.45 ± 2.96 years) were analyzed. Vaginal health index showed an improvement (p < 0.001) in both groups (from 12.54 ± 1.37 to 16.36 ± 2.66 for PCV, from 12.00 ± 1.91 to 16.60 ± 2.50 for HA), but the difference between final means (95%CI: -1.66 to 1.18) evidenced that PCV is non-inferior to HA treatment. Similarly, an improvement was evidenced in vaginal maturation index (p = 0.005 for PCV, ns. for HA), female sexual function index (p < 0.001 for PCV, p < 0.001 for HA), and SF-12 (p < 0.001 for PCV, p < 0.001 for HA), with no difference between groups. Safety was optimal and no adverse events were reported. CONCLUSIONS: The use of HA gel does not give additional benefits to those that are already provided by the moisturizing PCV.

User testing as a method for evaluating subjects' understanding of informed consent in clinical trials in multiple sclerosis.

The Patient Information Sheet (PIS) is an important aspect of the consent process in a clinical trial that provides potential participants the necessary information for deciding whether to take part in a specific study and for understanding their rights pertaining to participation. User Testing was originally developed to assess how written information about medicinal products performs with its intended users. User testing has been proposed in a small number of clinical trials and has been able to identify subjects' ability or inability to find and understand important information related to providing a valid consent to participate. A 21-item ad hoc user testing questionnaire was applied to 2 PIS used in clinical trials in MS. Sixty subjects were allocated to a group testing an observational study PIS (O-PIS) or to a group testing an intervention study PIS (I-PIS). In the O-PIS group, 19.4% of subjects located all relevant information within the text (21/21) and 3.4% of subjects in the I-PIS group. Overall, 82.1% of subjects testing the O-PIS understood the text and 53.5% of subjects testing the I-PIS understood the text. In the category 'nature and purpose of the trial', one-third of subjects did not understand the text, including the aim of the study. User testing should be considered as a valid tool in evaluating the comprehensibility of PIS in the context of clinical trials MS to assure that subjects provide a valid consent to participate.
