The Evolution of Hemophilia Care: Clinical and Laboratory Advances, Opportunities, and Challenges

2020

AbstractHemophilia A (HA) and B (HB) are X-linked bleeding disorders caused by mutations in the F8 or F9 gene that result in the absence, or reduced activity, of the corresponding clotting factor. The severity of bleeding and related complications is proportional to the amount of residual circulating functional factor. The development of a safe and effective hemophilia treatment lasted several decades and has been mainly based on clotting factor replacement. Advances in the engineering and manufacturing of clotting concentrates have led to the widespread availability of extended half-life products that reduced the number of intravenous infusions needed to achieve adequate trough levels. The…

Cetuximab-induced skin exanthema: prophylactic and reactive skin therapy are equally effective

2013

Purpose Treatment with cetuximab is accompanied by the development of an acneiform follicular skin exanthema in more than 80 % of patients. Severe exanthema (grade III/IV) develops in about 9–19 % of patients with the necessity of cetuximab dose reduction or cessation.

Ramucirumab in patients with previously treated advanced hepatocellular carcinoma: Impact of liver disease aetiology.

2021

BACKGROUND & AIMS Hepatocellular carcinoma (HCC) is a common complication of chronic liver disease with diverse underlying aetiologies. REACH/REACH-2 were global phase III studies investigating ramucirumab in advanced HCC (aHCC) following sorafenib treatment. We performed an exploratory analysis of outcomes by liver disease aetiology and baseline serum viral load. METHODS Meta-analysis was conducted in patients with aHCC and alpha-fetoprotein (AFP) ≥400 ng/mL (N = 542) from REACH/REACH-2 trials. Individual patient-level data were pooled with results reported by aetiology subgroup (hepatitis B [HBV] or C [HCV] and Other). Pre-treatment serum HBV DNA and HCV RNA were quantified using Roche CO…

Expression of inhibitory glycine receptors in postnatal rat cerebral cortex.

1993

The developmental expression of inhibitory glycine receptors was analyzed in postnatal rat cerebral cortex using the specific monoclonal antibody, MAb 4a. This antibody defines an epitope common to all known glycine receptor alpha-subunits. At birth, high levels of immunoreactivity were found, which transiently increased during the second postnatal week, but subsequently declined to low adult levels. Biochemical analysis of the MAb 4a antigen from parietal areas indicates that cortical glycine receptors correspond to the neonatal receptor isoform previously identified in spinal cord of newborn animals. Immunocytochemistry showed that, within 2 weeks after birth, MAb 4a-reactive glycine rece…

Diagnosis, monitoring and management of immune-related adverse drug reactions of anti-PD-1 antibody therapy.

2015

PD-1 checkpoint inhibitors are associated with a specific spectrum of immune-related adverse events. This spectrum is different from toxicities known for kinase inhibitors or cytotoxic drugs. Since PD-1 directed therapies show effectivity in an increasing number of malignant diseases, their clinical usage will increase rapidly. Therefore clinicians from different specialities such as medical oncology, internal medicine, family doctors and emergency unit staff should be aware of the adverse effects of PD-1 checkpoint inhibitors to avoid delays in diagnosis and treatment. Based on pooled data from pivotal trials as reported by the European Medicines Agency, the present paper reviews incidence…

Tartrate-Resistant Acid Phosphatase 5b: A Novel Serum Marker of Bone Resorption

2000

Human serum contains two forms of tartrate-resistant acid phosphatase (TRAP), 5a and 5b. Of these, 5a contains sialic acid and 5b does not. We show here that antigenic properties and pH optimum of TRAP purified from human osteoclasts are identical to those of serum TRAP 5b and completely different from those of serum TRAP 5a, suggesting that 5b would be derived from osteoclasts and 5a from some other source. We developed a novel immunoassay specific for 5b using a monoclonal antibody O1A as capture antibody. O1A did not bind acid phosphatase derived from platelets and erythrocytes. Western analysis showed that O1A was specific for TRAP in both human bone and serum. We measured bound TRAP ac…

Treatment effect of alirocumab according to age group, smoking status, and hypertension: Pooled analysis from 10 randomized ODYSSEY studies

2019

Background: Age, smoking, hypercholesterolemia, and hypertension are major risk factors for atherosclerotic cardiovascular disease. Objective: We examined whether the effects of alirocumab on low-density lipoprotein cholesterol (LDL-C) differed according to age, hypertension, or smoking status. Methods: Data were pooled from 10 Phase 3 ODYSSEY randomized trials (24–104 weeks’ duration) in 4983 people with heterozygous familial hypercholesterolemia (FH) or non–familial hypercholesterolemia (3188 on alirocumab, 1795 on control [620 on ezetimibe and 1175 on placebo]). Most participants received concomitant maximum tolerated statin therapy. In 8 trials, the alirocumab dose was increased from 75…
