Scheld Published 1 April 1993 Medicine Clinical Microbiology Reviews Bacterial meningitis remains a disease with associated unacceptable morbidity and mortality rates despite the availability of effective bactericidal antimicrobial therapy. Pathogenesis and pathophysiology of bacterial meningitis The pathogenesis and pathophysiology of bacterial meningitis involve a complex interplay between virulence factors of the pathogens and the host immune response [ 3,4 ]. Much of the damage from this infection is believed to result from cytokines released within the CSF as the host mounts an inflammatory response.

Meningitis pathophysiology - wikidoc Pathophysiology. The clinical picture of meningitis largely arises from the host response to the inciting organism in the CSF. It seems that the subcapsular components (the cell wall and lipopolysaccharide) of bacteria are more important in determining inflammation than the surface components ( pili and polysaccharide capsule).

Central Nervous System Systemic Lupus Erythematosus Jan 06, 2022 · Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by multiple immunologic abnormalities and has the potential to involve the central nervous system (CNS). The prevalence of SLE seems to be growing, possibly because of earlier diagnosis and improved survival; however, the associated mortality is still high. The mortality is … Pathogenesis and pathophysiology of bacterial meningitis Most cases of bacterial meningitis begin with host acquisition of a new organism by nasopharyngeal colonization followed by systemic invasion and development of a high-grade bacteremia. Bacterial encapsulation contributes to this bacteremia by inhibiting neutrophil phagocytosis and resisting classic complement-mediated bactericidal activity.

Motor neuron disease - Wikipedia Differential diagnosis can be challenging due to the number of overlapping symptoms, shared between several motor neuron diseases.

Pathophysiology - Bacterial Meningitis Many of the pathophysiologic consequences of bacterial meningitis result from virulence factor induced inflammation of the subarachnoid space. Cell Wall: The cell walls of gram positive bacteria such as S. pneumoniae trigger inflammation. More specifically, cell wall components such as teichoic acid and peptidoglycan induce severe inflammation.
