The influence of cefepime on opsonophagocytosis of bacteria.

The effect of subminimal inhibitory concentrations (sub-MICs) of a semi-synthetic beta-lactam antibiotic, cefepime (BMY 28142), was studied on the opsonophagocytosis by human polymorphonuclear leukocytes (PNMs) of strains of Escherichia coli, Klebsiella oxytoca and Staphylococcus aureus. Cefepime-treated Gram-negative bacteria were not better phagocytosed by PMNs; however the uptake of one of three S. aureus strains was enhanced. The effect of cefepime on the uptake of strains of E. coli was compared to that of two other beta-lactam antibiotics, mecillinam and ceftriaxone. Exposure of E. coli to sub-MICs of mecillinam and ceftriaxone enhanced phagocytosis by PMNs

Mycobacterium avium-infectie bij HIV-geïnfecteerde patiënten: epidemiologie, diagnose, profylaxe en behandeling

The prevalence of infection with Mycobacterium avium complex (MAC) has increased since the outbreak of the HIV pandemic. This complex comprises two organisms: M. avium (mostly) and M. intracellulare (rarely). The source of MAC infection is not known. The principal risk factors for disseminated MAC infection in a patient with HIV infection are a low CD4 count and a previous opportunistic infection. The symptoms of disseminated MAC infection resemble those of HIV wasting; a positive culture of normally sterile tissue confirms a MAC infection. There is reserve with regard to routine prophylaxis in HIV-infected persons because of the possible development of resistance, interaction with other drugs used in AIDS, toxicity and possible absorption disorders which might cause prophylaxis to fail. For the treatment of disseminated MAC infection, a combination of at least two medicaments (macrolides and ethambutol) is recommende
