Aim: To assess the safety and efficacy of an intravenous immunoglobulin (IVIG) 10% preparation (Panzyga; Octapharma AG, Lachen, Switzerland) in predominantly antibody-deficient children with primary immunodeficiency disease.

Methods: Data from two prospective, open-label and noncontrolled multicenter Phase III studies of IVIG 10% that included 25 patients <16 years of age were analyzed for efficacy, pharmacokinetics and safety.

Results: The rate of serious bacterial infections was 0.

Intravenous immunoglobulin (IVIG) therapy is commonly used to treat patients with primary antibody deficiency. This prospective, open-label, non-randomised, multicentre, phase III trial investigated the pharmacokinetics of a new 10% liquid IVIG product (panzyga®; Octapharma) in 51 patients aged 2-75 years with common variable immunodeficiency (n = 43) or X-linked agammaglobulinaemia (n = 8). Patients were treated with IVIG 10% every 3 (n = 21) or 4 weeks (n = 30) at a dose of 200-800 mg/kg for 12 months.

Purpose: To assess the efficacy and safety of panzyga® (intravenous immunoglobulin 10%) in preventing serious bacterial infections (SBIs) in patients with primary immunodeficiency diseases (PIDs), a prospective, open-label, multicenter, phase 3 study and an open-label extension study were undertaken.

Methods: Initially, the study drug (infusion rate ≤0.08 mL/kg/min) was administered at intervals of 3 or 4 weeks for 12 months, followed by 3 months of panzyga® at infusion rates increasing from 0.

Purpose: The previous studies with Flebogamma(®) 5 % DIF intravenous immunoglobulin (IVIG) contained insufficient numbers of pediatric subjects to fully warrant a pediatric indication by the FDA. The objective of this study was to evaluate the efficacy, safety, and pharmacokinetics of Flebogamma® 5 % DIF for replacement therapy in children (age 2-16) with primary immunodeficiency diseases (PIDD).

Methods: IVIG was administered at eight clinical sites to 24 subjects with well-defined PIDD at a dose of 300-800 mg/kg every 21-28 days for 12 months.

Conventional immunotherapy (IT) is effective in treating allergic rhinitis, allergic asthma, and chronic rhinosinusitis. Disadvantages include poor compliance, delayed efficacy, and patient frustration. Rush IT, or rapid desensitization, offers the advantages of rapid response, improved compliance, and cost-effectiveness.

One in four asthma patients may not have their condition adequately controlled despite being treated according to current practice guidelines, and these patients experience persistent symptoms, frequent exacerbations, and high healthcare utilization. The Allergy and Asthma Center, a recognized center of excellence in the treatment of allergy and asthma, is based on a patient-first philosophy, and this article explains how the practice operates and the importance of maintaining efficient office flow, implementing technology, and building a caring and dedicated staff Because asthma patients are often referred from primary care physicians, many present with difficult-to-treat disease. Even though many of these patients have received inhaled corticosteroids either alone or in combination with other medications, their condition still remains not well controlled.

Rapid allergen vaccination (RAV) is the updated term for what was previously called rush immunotherapy and rapid desensitization. RAV offers several advantages over traditional immunotherapy--that is, conventional allergen vaccination (CAV)--in terms of faster efficacy, better compliance, and cost-effectiveness. We used a 3-hour RAV protocol to treat 137 allergy patients.

Purpose: To evaluate the response of patients who underwent both skin and in vitro allergy testing, both of which are accepted methods.

Data Sources: Retrospective review of the case notes of 100 patients evaluated by both testing methods for allergic disease.

Conclusions: A total of 62 patients (62%) tested positive to at least one of the tested allergens via the in vitro method.
