Evaluation of pharmacokinetics, efficacy and safety of ImmunateŽ solvent detergent in previously treated patients with severe haemophilia A

HAEMOPHILIA, Issue 1 2007
L. NEMES
Summary., ImmunateŽ Solvent Detergent (S/D) is a plasma derived, purified, human factor VIII (FVIII) , von Willebrand factor (VWF) complex subjected to two virus inactivation/removal processes: S/D and vapor heat treatment. This prospective, multicentre, three-part clinical study evaluated the pharmacokinetics (in comparison to the predecessor product ImmunateŽ), efficacy and safety of ImmunateŽ S/D in 56 previously treated patients with severe haemophilia A. Subjects received ImmunateŽ S/D on-demand, as a prophylactic regimen or both. The results of the pharmacokinetic population demonstrate that ImmunateŽ and ImmunateŽ S/D were equivalent with respect to the FVIII , and to the retrospectively VWF , parameters assessed. A total of 623 bleeding episodes were reported in 47/56 subjects. The duration of prophylaxis ranged from 0.1--5.2 months with a total of 175.6 months. The median number of bleeds per month in subjects on prophylaxis was 0 (range 0--10). Ninety-six percent of bleeding episodes were rated as having an excellent or good response. For most bleeding episodes (89%), subjects required only one infusion with a mean dose of 29.6 IU kg,1. No FVIII inhibitory antibodies were observed in any subject. No related serious adverse events were reported. Thus, the introduction of S/D treatment did not alter the PK characteristics and function of VWF and FVIII molecules of ImmunateŽ S/D which is effective and safe for treatment of bleeding episodes, management of surgical procedures, and prophylaxis.

Dramatic Improvement of Pyoderma Gangrenosum with Infliximab in a Patient with PAPA Syndrome

PEDIATRIC DERMATOLOGY, Issue 3 2005
Dorothee S. Stichweh M.D.
Patients with the syndromic triad of pyogenic sterile arthritis, pyoderma gangrenosum, and acne, an autoinflammatory process caused by mutations in the CD2 binding protein-1 (CD2BP1) gene, can have severe pyoderma gangrenosum. We describe a 14-year-old patient with this syndrome who was unresponsive to multiple therapies. A dramatic improvement in his pyoderma gangrenosum was observed after one infusion of infliximab, and a second infusion led to its resolution. Our observation extends the therapeutic use of infliximab to this component of PAPA syndrome. [source]

Hidradenitis suppurativa responding to treatment with infliximab

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 3 2010
Anita Lasocki
ABSTRACT A series of four cases of severe recalcitrant hidradenitis suppurativa treated with infliximab is presented. All patients had failed to respond to prior medical and surgical management. Baseline Quantiferon-TB Gold and chest radiograph were carried out before commencement of treatment. No patients had associated Crohn's disease. All patients received induction infusions of infliximab 5 mg/kg at weeks 0, 2 and 6, followed by eight weekly maintenance infusions. The total number of infusions varied between 4 and 6. Skin photography with Sartorius scoring was used to evaluate response to treatment. All patients experienced marked improvement in their disease activity, with a mean 48% improvement in Sartorius score after one infusion (week 2, P < 0.01), and 70% improvement after three infusions (week 14, P < 0.01). Time to relapse following cessation of therapy ranged from 6 weeks to 4 months. Further studies examining the efficacy of infliximab and its effect on the course of the disease, particularly relating to long-term management, are required. [source]

Effect of high-dose intravenous immunoglobulin in delayed pressure urticaria

BRITISH JOURNAL OF DERMATOLOGY, Issue 4 2003
G. Dawn
Summary Background Delayed pressure urticaria (DPU) is difficult to treat. High-dose intravenous immunoglobulin (IVIG) has been found to be effective in treating patients with autoimmune chronic urticaria. Objectives To report the effect of IVIG on eight patients with severe unremitting DPU. Methods IVIG was administered at a dose of 2 g kg,1 over 2,3 days on an in-patient basis. The response to treatment was assessed subjectively and recorded as remission, improved or unchanged. An autologous serum skin test (ASST) was performed in seven patients. Results Three of eight patients achieved remission; two after one infusion and one after three infusions. Two patients improved. Three patients remained unchanged; of these, two declined further treatment after two infusions, and one failed to improve after six infusions at monthly intervals. Four of seven patients had positive ASST; three responded to IVIG. Two developed delayed positive ASST; both responded to IVIG. Of three patients with negative ASST, two responded. Conclusions IVIG induced remission or improved symptoms in five of eight patients with DPU with severe unremitting disease who had failed to respond to other therapies or were controlled only with systemic corticosteroids. Those who responded did so with three or fewer infusions. ASST is not a reliable predictor of response to IVIG. [source]
