Adverse effects of danazol prophylaxis on the lipid profiles of patients with hereditary angioedema.

Background: Hereditary angioedema (HAE) is a rare disorder caused by the deficiency of the C1-inhibitor gene (C1INH) . Patients experience recurrent bouts of edema, which can occur in almost any region of the body. As regards the treatment of the disease, danazol (an attenuated androgen) is used, among other agents, for long-term prophylaxis.

Association of high serum concentration of the third component of complement (C3) with pre-existing severe coronary artery disease and new vascular events in women.

Atherosclerosis is an inflammatory disease. The complement system plays an important role in the atherosclerotic process. However, lesser data is available on the possible role of C3 as a risk factor for atherosclerosis.

[C-reactive protein levels determined by an ultrasensitive method in a healthy Hungarian population].

Introduction: C-reactive protein (CRP) is a well-known acute phase protein. The concentration of CRP in serum is increased in response to inflammatory stimuli. Increased levels serve to identify organic disease, to monitor disease activity and to assist differential diagnosis.

Paradoxical alteration of acute-phase protein levels in patients with chronic hepatitis C treated with IFN-alpha2b.

Previously we observed elevation of the serum concentration of two acute-phase protein (AFP) complement components (C9 and C1-inhibitor) in patients with chronic hepatitis C who responded (R) to IFN-alpha therapy, but not in non-responders (NR). In the present study we investigated the effect of high-dose IFN-alpha therapy on serum concentrations of two positive [orosomucoid (OROSO) and C-reactive protein (CRP)] and two negative [transferrin (TF) and fetuin/alpha2HS-glycoprotein (AHSG)] AFP in an outpatient setting. We investigated blood samples of 40 patients with chronic hepatitis C at the onset and at the end of a 3-month treatment with high-dose IFN-alpha2b (5 MIU/day for 6 weeks, followed by 5 MIU t.

Hyperleptinemia, visceral adiposity, and decreased glucose tolerance in mice with a targeted disruption of the histidine decarboxylase gene.

Histamine has been referred to as an anorexic factor that decreases appetite and fat accumulation and affects feeding behavior. Tuberomammillary histaminergic neurons have been implicated in central mediation of peripheral metabolic signals such as leptin, and centrally released histamine inhibits ob gene expression. Here we have characterized the metabolic phenotype of mice that completely lack the ability to produce histamine because of targeted disruption of the key enzyme in histamine biosynthesis (histidine decarboxylase, HDC).
