Efficacy of a Novel Intranasal Formulation of Azelastine Hydrochloride and Fluticasone Propionate, Delivered in a Single Spray, for the Treatment of Seasonal Allergic Rhinitis: Results from Russia.

BACKGROUND: The novel intranasal formulation of azelastine hydrochloride (AZE) and fluticasone propionate (FP) in a single spray (MP-AzeFlu) was compared with a first-line intranasal antihistamine spray (AZE) in Russian seasonal allergic rhinitis (SAR) patients. METHODS: Moderate-to-severe SAR/rhinoconjunctivitis patients (n = 149; aged 18-65 years) were randomized to receive MP-AzeFlu (137/50 µg AZE/FP per spray) or AZE (137 µg/spray), both as 1 spray/nostril twice daily, in a multicenter, open-label, 14-day, parallel-group trial. The primary outcome was change from baseline in morning and evening reflective total nasal symptom score (rTNSS). Secondary end points included: change from baseline in reflective total ocular symptom score (rTOSS), reflective total of 7 symptom scores (rT7SS), 28-item Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) overall score, and EuroQol-5D (EQ-5D) questionnaire score. RESULTS: When compared with AZE-treated patients, those treated with MP-AzeFlu experienced significantly greater reductions in rTNSS (difference: -2.47; 95% confidence interval [CI] -3.65 to -1.30; p < 0.001), rTOSS (difference: -1.62; 95% CI -2.32 to -0.92; p < 0.001), and rT7SS (difference: -4.34; 95% CI -5.98 to -2.70; p < 0.001). Superior relief observed on day 2 with MP-AzeFlu versus AZE was sustained throughout the study. MP-AzeFlu-treated patients experienced a greater improvement in QoL than AZE-treated patients as measured by overall RQLQ score (mean ± SD 2.91 ± 1.08 vs. 2.05 ± 1.15) and EQ-5D score (mean ± SD 87.4 ± 10.3 vs. 83.0 ± 12.8). MP-AzeFlu was well tolerated. CONCLUSIONS: MP-AzeFlu was superior to AZE in reducing moderate-to-severe SAR symptoms, providing earlier and more complete symptom relief.

Major approaches in early diagnostics of common variable immunodeficiency in adults in Moscow.

Common variable immunodeficiency (CVID) is a primary immunological disease characterized predominantly by hypogammaglobulinemia. The main clinical manifestations are severe recurrent infections that often lead to structural damage of affected organs. The early start of adequate intravenous immunoglobulin therapy has significantly improved the prognosis of this serious disorder. Patients with CVID are also predisposed to autoimmune and lymphoproliferative complications. This article deals with the features of this primary immunodeficiency in adults. Clinical manifestations, immunological features and treatment concepts were gathered during 21 years of observation of such patients in Moscow. The authors suggest early predictive clinical signs of CVID in adults.
