OBJECTIVE Mitochondrial dysfunctions have been associated with the pathogenesis of sepsis. A systematic survey of mitochondrial function in brain tissues during sepsis is lacking. In the present work, we investigate brain mitochondrial function in a septic mouse model. DESIGN Prospective animal study. SETTING University research laboratory. SUBJECTS(More)
The chemokine monocyte chemoattractant protein 1/CC chemokine ligand 2 (MCP-1/CCL2) is a potent chemoattractant of mononuclear cells and a regulatory mediator involved in a variety of inflammatory diseases. In the present study, we demonstrate that mcp-1/ccl2-deficient mice are more susceptible to systemic inflammatory response syndrome induced by(More)
Current evidence indicates that dysregulation of the host inflammatory response to infectious agents is central to the mortality of patients with sepsis and in those with systemic inflammatory response syndrome. Strategies to block inflammatory mediators, often with complicated outcomes, are currently being investigated as new adjuvant therapies for sepsis.(More)
Experimental and clinical studies in sepsis indicate that antibiotic therapy may induce the release of endotoxin (LPS) from the outer membrane of gram-negative bacteria and therefore may affect the physiologic response and survival. The aim of this study was to evaluate if antibiotics commonly used to treat secondary peritonitis are capable of changing(More)
INTRODUCTION New challenges have arisen for the management of critically ill HIV/AIDS patients. Severe sepsis has emerged as a common cause of intensive care unit (ICU) admission for those living with HIV/AIDS. Contrastingly, HIV/AIDS patients have been systematically excluded from sepsis studies, limiting the understanding of the impact of sepsis in this(More)
INTRODUCTION In recent years, the incidence of sepsis has increased in critically ill HIV/AIDS patients, and the presence of severe sepsis emerged as a major determinant of outcomes in this population. The inflammatory response and deregulated cytokine production play key roles in the pathophysiology of sepsis; however, these mechanisms have not been fully(More)
OBJECTIVES To assess the temporal trends in incidence of AIDS-defining opportunistic illnesses in an urban cohort of a middle-income country. METHODS HIV infected patients aged ≥ 18 years at cohort entry were included in this analysis. We calculated incidence rates per 1000 persons-years of observation for the first opportunistic illness presented after(More)
BACKGROUND Opportunistic illnesses still account for a huge proportion of hospitalizations and deaths among HIV-infected patients in the post combination antiretroviral therapy (cART) era, particularly in middle- and low-income countries. The aim of this study was to assess predictors of the top four most incident opportunistic illnesses (tuberculosis,(More)
