In this Disease-modifying drugs for multiple sclerosis Page 58 of 120 Final Report Update 1 Drug Effectiveness Review Project analysis cheap feldene 20mg line arthritis in dogs back legs, we have pooled only to the same dose and dosing schedule of interferon beta-1a SC ® (Rebif ) purchase 20mg feldene overnight delivery arthritis meaning. In the head-to-head trials comparing the beta interferon products, adverse events were not 41 well reported, with 2 of the 5 trials not reporting adverse events. The dose of interferon beta-1a ® SC (Rebif ) was 22 µg weekly in the Koch-Henrisksen study and they only reported combined incidence for a few selected adverse events. Withdrawal or early discontinuation due to an adverse event or any other reason was not found to be different between this low dose of ® ® interferon beta-1a SC (Rebif ) and interferon beta-1b (Betaseron ) 250 µg. Typical adverse events reported included flu-like symptoms, injection-site reactions, fever, and withdrawal. The comparative frequency of these events is outlined in the section that follows. The Cochrane systematic review of placebo-controlled trials in patients with relapsing- remitting multiple sclerosis evaluated the frequency of adverse events, reporting only on the 44 ® µg dosing of interferon beta-1a (Rebif ) however they did include data from a once weekly dosing schedule from the OWIMS trial. Only 3 times weekly ® interferon beta-1a SC (Rebif ) was not associated with significantly increased rates of flu-like syndrome, fever, and myalgias (Table 24). The incidence of leukopenia, however, was ® significantly higher with 3 times weekly interferon beta-1a SC (Rebif ), while interferon beta-1b ® ® SC (Betaseron ) and interferon beta-1a IM (Avonex ) were not. Comparing the 2 dosing ® regimens of interferon beta-1a SC (Rebif ), dosing once weekly resulted in statistically significantly greater rates of flu-like syndrome, fever, and headache while dosing 3 times weekly ® did not. Of note, standard dosing for (Rebif ) is 3 times weekly.

Two of these trials used a ® 22 µg dose of interferon beta-1a SC (Rebif ) and for this reason we only pooled this dose for adverse event analysis. Pooled analysis of these trials suggested significantly higher rates of injection site reaction, abnormal liver function tests, and withdrawal due to adverse events with ® interferon beta-1a SC (Rebif ) 22 µg and flu-like syndrome and withdrawal due to adverse ® events with interferon beta-1b SC (Betaseron ) compared with placebo (Table 25).

There was no difference in the frequency of fatigue (relative risk, 1. Of the 5 observational studies in patients with relapsing-remitting multiple sclerosis, 3 met inclusion criteria for both effectiveness and harms analysis, and the best of these was a retrospective cohort study based on data from patients in Austria, Switzerland, and Germany, 49 with 4754 patients exposed to 1 of the 3 interferons. An analysis of the reasons for discontinuation of treatment indicated that discontinuations due to injection site reactions were ® significantly lower in the interferon beta-1a (Avonex ) 30 µg IM weekly group compared with ® either the interferon beta-1a SC (Rebif ) 22 mcg SC 3 times weekly or interferon beta-1b ® (Betaseron ) 250 µg SC every other day groups, but no different than the interferon beta-1a SC ® (Rebif ) 44µg SC twice weekly group. Differences in frequency of flu-like syndrome was ® statistically significant only for interferon beta-1a SC (Rebif ) 22 mcg group compared with the ® ® interferon beta-1b (Betaseron ) group with the interferon beta-1a SC (Rebif ) 22 mcg being ® lower. Discontinuations due to lack of efficacy was greatest in the interferon beta-1a SC (Rebif ) ® 22 mcg group, compared with the interferon beta-1a IM (Avonex ) group or the interferon beta- ® 1b (Betaseron ) group (Table 26). The other 2 studies were of patients being treated at large multiple sclerosis specialty centers (1 in Spain, 1 in Italy), enrolled and followed every 3 46, 47 months. These studies had a high risk of bias due to clinically important differences among ® groups at baseline, and because at the outset of data collection only Betaseron was marketed in ® ® those countries, while Avonex and Rebif were approved during the time period of the study.

The observational study by Rio et al provided a median of 60 months of follow-up (range 12-115 months) on 146 patients receiving interferon beta-1b ® 150 (Betaseron ). They observed 4 deaths (3 sepsis and 1 pulmonary hemorrhage), 1 intracerebral hemorrhage, and 1 gastrointestinal hemorrhage, all of which were unexpected adverse events.

Scully2 1Centre for Haematology, Imperial College London, London, United Kingdom; and 2Department of Haematology, University College London Hospital, London, United Kingdom VWF is a multimeric plasma glycoprotein that speciﬁcally recruits platelets to sites of vessel injury. VWF multimeric size is central to this function, with larger multimers being more hemostatically active. Regulation of VWF multimeric size is mediated by the plasma metalloprotease ADAMTS13 (ADisintegrin And Metalloproteinase with ThromboSpondin type 1 motifs, member 13). This enzyme can only recognize and cleave VWF when it is unraveled by rheological shear forces of the ﬂowing blood. After the exposure of cryptic exosites, VWF recognition by ADAMTS13 involves multiple interactions that enable the protease to cleave VWF. Loss of VWF multimer size regulation caused by severe ADAMTS13 deﬁciency (either inherited or acquired) is associated with the microvascular thrombotic disorder thrombotic thrombocytopenic purpura (TTP). The sequelae associated with TTP are widely thought to be linked to hyperreactive circulating VWF that cause unwanted platelet aggregation in the high shear environment of the microvasculature. Diagnosis of TTP is primarily made through a combination of symptoms, analysis of plasma ADAMTS13 activity, and detection of inhibitory anti-ADAMTS13 antibodies. Current frontline treatments for TTP include plasma exchange, which serves to remove inhibitory antibodies (in acquired TTP) and provide a source of functional ADAMTS13, and steroids to treat the autoimmune component of acquired TTP. The use of anti-CD20 therapy has also exhibited encouraging results in the treatment of acquired TTP. Newer therapeutic strategies that are currently being explored or are in development include recombinant ADAMTS13, a hyperreactive ADAMTS13 variant, and anti-VWF therapy. This review discusses the basic biochemistry of VWF and ADAMTS13, their dysfunction in TTP, and therapeutic approaches for the amelioration of TTP. Conversely, the GpIb -binding site in the VWF A1 VWF is a multimeric plasma glycoprotein that is critical for platelet domain is partially concealed, preventing any interaction between tethering at sites of blood vessel damage and therefore is essential circulating platelets and VWF while in its circulating globular for normal hemostasis. Similarly, the VWF A2 domain, which contains cells and megakaryocytes. The nascent translated VWF polypeptide ADAMTS13 binding and a cleavage site(s) and separates the A1 contains a signal peptide, a propeptide (D1-D2 domains) and a and A3 domains, is folded such that the cleavage site is completely recently reassigned domain organization consisting of D -D3-A1- buried within the domain, rendering globular VWF resistant to A2-A3-D4-C1-C2-C3-C4-C5-C6-CK that contains several speciﬁc proteolysis. The circulating collagen in the A3 domain, and platelet integrin IIb 3 in the (now globular form allows VWF to survey the intact vasculature without termed) C4 domain.
