Comparative Case Study of Efficacy of Oral Bilastine Monotherapy to Concomittant Administration of Oral Bilastine with Probiotic in Patients with Allergic Rhinitis

IntroductionAllergic rhinitis continues to pose a global burden in both adult and paediatric population and requires adequate medical therapy to avoid long term complications making it a challenging concern. This prompts the need to find a suitable and appropriate treatment regimen for this condition.AimTo study the clinical efficacy of Oral Bilastine and Probiotics in patients with allergic rhinitis. To compare the effectiveness of Bilastine monotherapy to Oral Bilastine combined with Probiotics in patients with allergic rhinitis.Materials and MethodsTotal of 100 patients were selected and randomized into two groups- Group 1 and Group 2 and were treated with Oral Bilastine 20 mg OD and Oral Bilastine 20 mg with Oral Probiotics OD (Lactobacillus fermentum & L. paracasei - 4 billion cells) respectively to maintain uniformity. Baseline scoring and follow up scoring after 6 weeks was done using the Total symptom score, Absolute eosinophil count and Nasal smear eosinophil count and were evaluated and documented as per their response to treatment.ResultsA significant reduction was observed in the severity of symptoms especially nasal obstruction, sneezing in patients of both groups along with extra nasal symptoms, with average mean score in Group 1 being 7.72 before treatment that reduced to 3.66 and that of Group 2 from 9.32 to 5.02. The mean score of Group 2 was greater in both before and after treatment which is highly significant. (p < 0.001)ConclusionMonotherapy with Oral Bilastine has proven in relieving allergic symptoms. Addition of Oral Probiotics along with Bilastine has shown to have synergistic effect in further improving overall symptoms in allergic rhinitis.
