Posterior reversible encephalopathy syndrome (PRES) is a rare clinical entity associated with systemic lupus erythematosus which characterized by seizure, headache, and altered mental status. The pathophysiology involves subcortical vasogenic edema secondary to hypertension and endothelial damage. PRES is reversible with withdrawal of the offending agent, strict blood pressure control, and treating the underlying disease. We report present here a patient with lupus nephritis who developed PRES following mycophenolate administration...

BACKGROUND: Giant cell arteritis (GCA) is a chronic vasculitis of large and medium vessels in which no targetable biomarkers exist to allow selective treatment, predict disease activity and monitor therapeutic responses. The accessibility of the temporal artery (TA) for biopsy allows morphologic studies to characterize macrophages and T cells in the microenvironment of the arterial wall. We evaluated the expression of folate receptor beta (FRB), a candidate diagnostic/therapeutic biomarker, compared its expression with key macrophage markers and correlated it with GCA severity...

Autoantibody (autoAb) response is an important arm of endogenously arising anti-tumor immune responses, and has received new attention as a cancer biomarker with the recent success of immune check-point inhibitor therapy. Our laboratory has been focusing on measuring autoAb against B-cell epitopes in order to bypass the necessity to purify a panel of recombinant proteins. In order to optimize peptide-based autoAb measurement and to increase sensitivities to cover more patients, we developed a new approach of using mixed peptides to conjugate on the same microsphere and compared its results with the use of a dominant peptide epitope using Luminex microbead-based multiplex assays...

Immunoglobulin replacement therapy (IRT) is standard treatment for patients with primary immunodeficiency (PID). Because most of the patients with PID will require long life-time immunoglobulin replacement therapy, the quality of the prescribed products is of utmost importance. The IRT is generally administered either intravenously (abbreviated IVIG), or subcutaneously (abbreviated SCIG). Both routes have been demonstrated to be effective. The preferred route may vary at different times during a given patient's life...

The nonsteroidal anti-inflammatory drug (NSAID) Celecoxib (Celebrex®) received Food and Drug Administration (FDA) approval in 1998 for treatment of osteoarthritis and rheumatoid arthritis, and in recent years, its use has been extended to various types of malignancies, such as breast, colon, and urinary cancers. To maintain the survival of malignant B cells, non-Hodgkin's Lymphoma (NHL) is highly dependent on inflammatory microenvironment, and is inhibited by celecoxib. Celecoxib hinders tumor growth interacting with various apoptotic genes, such as cyclooxygenase-2 (Cox-2), B-cell lymphoma 2 (Bcl-2) family, phosphor-inositide-3 kinase/serine-threonine-specific protein kinase (PI3K/Akt), and inhibitors of apoptosis proteins (IAP) family...

Severe Plasmodium falciparum malaria anemia (SMA) is a major cause of mortality in pediatric wards. Variations in inflammatory mediator production play an essential role in disease outcomes. Indeed, several studies have shown the involvement of pro- and anti-inflammatory cytokines such as IFN-γ, IL-6, TNF-α and IL-10 in malaria immunopathology. In other hand the exact role of Th17 cytokines such as IL-17, IL-22 and IL-21 in malaria remains poorly documented. Here, we investigated IFN-γ, TNF-α, IL-6, IL-12, IL-10, IL-4, IL-13, IL-17, IL-22 and IL-21 circulating levels and their association with malaria anemia and parasitemia in Gabonese children...

Coenzyme Q10, (CoQ10) an electron transporter and an antioxidant, protects a variety of cell types against oxidative stress and apoptosis. However, protective effect of CoQ10 on oxidative stress-induced apoptosis in lymphocytes has not been studied in detail. In this study, we investigated the effect of CoQ10 on oxidative stress-induced apoptosis in lymphocytes. An exposure of peripheral blood lymphocytes to oxidative stressors, rotenone or hydrogen peroxide, lead to apoptosis. Pre-treatment of lymphocytes with CoQ10 resulted in a significantly reduced level of oxidative stress-induced apoptosis, which was associated with decreased reactive oxygen species production, an inhibition of mitochondrial membrane depolarization, and inhibition of activation of caspase-9 and caspase-3...

Exposure to ambient ozone causes airway hyperreactivity and lung inflammation, which represent an important health concern in humans. Recent clinical and experimental studies contributed to the understanding of the mechanisms of epithelial injury, inflammation and airway hyperreactivity, which is reviewed here. The present data suggest that ozone induced oxidative stress causes inflammasome activation with the release of IL-1, other cytokines and proteases driving lung inflammation leading to the destruction of alveolar epithelia with emphysema and respiratory failure...

Lung cancer is the most commonly diagnosed cancer as well as the leading cause of cancer-related deaths worldwide. To date, surgery is the first choice treatment, but most clinically diagnosed cases are inoperable. While chemotherapy and/or radiotherapy are the next considered options for such cases, these treatment modalities have adverse effects and are sometimes lethal to patients. Thus, new effective strategies with minimal side effects are urgently needed. Cancer immunotherapy provides either active or passive immunity to target tumors...

Many inflammatory chemokines release from leukocytes and pancreatic acinar cells which play important roles in pathophysiology of acute pancreatitis (AP). Of interests, CXCL2 and CCL2 have been shown elevated in the plasma of patients with AP. We have recently found that Glycyrrhizin (GZ) attenuates AP in mice model. In this study, we aimed to investigate the direct effect of GZ on expression levels of CCL2 and CXCl2 in isolated pancreatic acinar cells. Isolated acinar cells were isolated from the pancreas of healthy C57BL/6 mice, stimulated with cerulein (10(-7) M) and then treated with either PBS or different doses of GZ...
