The effects of oral supplements with Sambucus nigra, Zinc, Tyndallized Lactobacillus acidophilus (HA122), Arabinogalactans, vitamin D, vitamin E and vitamin C in otitis media with effusion in children: a randomized controlled trial.

OBJECTIVE: To evaluate the ability of oral supplements with immune-stimulating molecules (Sambucus nigra, Zinc, Tyndallized Lactobacillus acidophilus (HA122), Arabinogalactans, vitamin D, vitamin E and vitamin C) to reduce the inflammation of the upper airway tract and improve the outcome of otitis media with effusion (OME) in children. PATIENTS AND METHODS: Randomized controlled trial. One-hundred ninety-eight children (CI 95%: 12-96 months) were divided into four groups. Group 1 (48 subjects) received 10 ml of oral supplements (OS) with immune-stimulating molecules for three months (20 days consecutively, then 10 days of suspension - the therapeutic scheme was repeated three times); Group 2 (54 children) underwent treatment with 10 ml of OS for 90 consecutive days; Group 3 (48 subjects) received 15 ml of OS for 45 consecutive days; a control group (48 children) underwent the standard treatment for rhinitis and OME. Outcome measures included otoscopy, tympanometry, fibroendoscopy, and the pure tone audiometry (PTA) at T0 (before treatment), T1 (45 days after treatment), and T2 (90 days after treatment). RESULTS: All children treated with OS showed a reduction of Upper Airway Infection (UAI) episodes and OME compared to the control group independent of the administration method and posology. The three groups treated with OS showed statistically significant differences between T0 and T2 for otoscopy, tympanometry, fibroendoscopy, and PTA. In Group 2, the otoscopy and the tympanometry scores improved at T1. Group 2 and 3 had better PTA results than Group 1. CONCLUSIONS: OS with immune-stimulating molecules should be considered as a supporting therapy in children affected by recurrent episodes of UAI associated with OME due to their capacity to improve the immune response and reduce the inflammatory phenomena. OS can improve the fibroendoscopic findings by restoring middle ear ventilation, in addition to their ability to reduce inflammation in the middle ear.

Clinical and immunological effects of a treatment with desentizating low-dose multicomponents in IgE mediated and non IgE mediated food allergies: observational retrospective pilot study.

BACKGROUND: Alimentary allergy has high impact on the quality of life (Qol) of patients and their families: it represents an economic burden for individuals and National Health System. The disease, particularly frequent in pediatric age, recognizes different pathogenetic mechanisms and expresses itself through the production of IgE (IgE mediated form) antibodies or through cell-mediated immunune responses (non IgE mediated forms). The aim of this clinical observational retrospective study is to evaluate the effect of a long-term treatment with Low Dose Medicine (LDM) drugs in pediatric patients affected by IgE and non IgE mediated food allergy. OBJECTIVE: The purpose of the study is to determine the efficacy of the treatment with Allergy Plex (Guna Laboratory, Milan, Italy) to induce clinical and/or immunological tolerance both to IgE mediated and non IgE mediated food allergy; the secondary endpoint is to investigate the treatment tolerability, the reduction of positivity to Skin Prick test and Patch test to food allergens and the decrease on the peripheral blood of the specific IgE to food allergens. The treatment efficacy was measured through a clinical score. METHODS: In this study the immunomodulant activity of Allergy Plex 13, Allergy Plex 7 and Allergy Plex 10 (Guna S.p.A., Milano, Italy) was evaluated. In every patient the state of allergical clinical responses and the immuno-allergological state were evaluated by means of specific parameters letting know the regulatory response to the allergical Th fenotype. RESULTS: Data about Clinical tolerance to food, Symptomatological clinical score, ECP, ACTH, Cortisol; IL-4, IL-10 was collected. There was evidence of improvement of clinical score, reduction of the diameter of cutaneous pomphus obtained through the Prick test and a decrease of IgE specifics values. CONCLUSIONS: The data issued from this study seem to confirm the efficacy of treatment with Allergy Plex in allowing the restoration of immune tolerance and the definite reduction of the clinical score.

Resting state functional thalamic connectivity abnormalities in patients with post-stroke sleep apnoea: a pilot case-control study.

OBJECTIVE: Sleep apnoea is common after stroke, and has adverse effects on the clinical outcome of affected cases. Its pathophysiological mechanisms are only partially known. Increases in brain connectivity after stroke might influence networks involved in arousal modulation and breathing control. The aim of this study was to investigate the resting state functional MRI thalamic hyper-connectivity of stroke patients affected by sleep apnoea (SA) with respect to cases not affected, and to healthy controls (HC). PATIENTS AND METHODS: A series of stabilized strokes were submitted to 3T resting state functional MRI imaging and full polysomnography. The ventral-posterior-lateral thalamic nucleus was used as seed. RESULTS: At the between groups comparison analysis, in SA cases versus HC, the regions significantly hyper-connected with the seed were those encoding noxious threats (frontal eye field, somatosensory association, secondary visual cortices). Comparisons between SA cases versus those without SA revealed in the former group significantly increased connectivity with regions modulating the response to stimuli independently to their potentiality of threat (prefrontal, primary and somatosensory association, superolateral and medial-inferior temporal, associative and secondary occipital ones). Further significantly functionally hyper-connections were documented with regions involved also in the modulation of breathing during sleep (pons, midbrain, cerebellum, posterior cingulate cortices), and in the modulation of breathing response to chemical variations (anterior, posterior and para-hippocampal cingulate cortices). CONCLUSIONS: Our preliminary data support the presence of functional hyper connectivity in thalamic circuits modulating sensorial stimuli, in patients with post-stroke sleep apnoea, possibly influencing both their arousal ability and breathing modulation during sleep.
