There is now evidence that repeated administration of interferon-alpha (IFN-alpha) to patients with chronic active hepatitis and cancers induces depressive symptoms. There is also evidence that induction of the cytokine network modulates the serotonergic system and that major depression is related to activation of the cytokine network and disturbances in(More)
OBJECTIVE Despite increased information on the importance of an inappropriate inflammatory response in the acute Charcot process, there has been no previous attempt to define the specific pathways that mediate its pathogenesis. Here, the role played by monocytes was analyzed. RESEARCH DESIGN AND METHODS The immune phenotype of peripheral monocytes was(More)
The purpose of this study was to retrospectively determine the safety and effectiveness of percutaneous cryoablation, monitored with computed tomography (CT) and ultrasonographic (US) guidance, for the treatment of hepatocellular carcinoma (HCC). Four patients with small HCCs underwent one percutaneous cryoablation treatment session monitored with CT and US(More)
CD40 ligand (CD40L) stimulation induces proinflammatory and immunomodulatory activity in monocytes. Here, we report on the effects of the steroid hormone 1alpha,25-dihydroxyvitamin D3 (1,25D3) on human blood monocytes that have been stimulated with the CD40L ligand. Co-treatment of CD40L-stimulated monocytes with 1,25D3 resulted in reduced production and(More)
Immunotherapy with interferon-alpha (IFNalpha) may induce depressive symptoms, anxiety and major depression when administered for at least 1-3 months at a dose of 3-10 MUI daily, twice or three times a week. Previously, it has been shown that immunotherapy with interleukin-2 (IL-2) significantly induces the cytokine network, as measured by increases in(More)
It has been suggested that a defective adaptive immune response contributes to septic immunosuppression. Here, the response of monocytes to CD40 ligand (CD40L) for patients with sepsis due to infection with gram-negative organisms has been analyzed. Compared to cells from controls, monocytes from septic patients showed significantly reduced production of(More)
Cholestasis, induced by liver ischemia-reperfusion injury (IRI), is characterized by dilatation of bile canaliculi and loss of microvilli. Tauroursodeoxycholic acid (TUDCA) is an anti-cholestatic agent, modulating protein kinase C (PKC) alpha pathway. PKC reduces ischemic damage in several organs, its isoform alpha modulates ezrin, a key protein in the(More)
We have shown that treatment with interleukin-2 (IL-2) or interferon-alpha (IFN alpha) may induce depressive symptoms and activation of the cytokine network and that IL-2 treatment may diminish serum dipeptidyl pepdidase IV (DPP IV) activity. DPP IV (EC is a membrane bound serine protease which catalyzes the cleavage of some cytokines and(More)
Inherited mutations of the Fas/Apo1/CD95 gene, a cell-surface receptor involved in cell death signaling and in the control of self-reactivity, characterize the recently identified autoimmune lymphoproliferative syndromes. A patient with type 2 autoimmune hepatitis with the immunologic and genetic features of autoimmune lymphoproliferative syndrome is(More)
A sustained response to standard interferon therapy for chronic hepatitis C has been demonstrated in no more than 25% of patients. To improve interferon alfa (IFN-alpha) antiviral effect, a number of combination therapies with IFNs plus other drugs have been proposed for both relapser and nonresponder hepatitis C virus (HCV)-infected patients. Although the(More)
