Deferoxamine and eflornithine (DL-alpha-difluoromethylornithine) in a rat model of Pneumocystis carinii pneumonia.
The iron chelator deferoxamine and the polyamine biosynthesis inhibitor eflornithine (DL-alpha-difluoromethylornithine) were examined for anti-Pneumocystis carinii activity in the rat model of P. carinii pneumonia. The activity of deferoxamine at 250, 500, and 1,000 mg/kg given intraperitoneally provides evidence that iron chelation is a promising novel approach to P. carinii chemotherapy. Resu...
متن کاملAction of deferoxamine against Pneumocystis carinii.
We found earlier that deferoxamine (DFO), a drug used for treatment of iron overload, is active against a rat model of Pneumocystis carinii pneumonia (PCP). We had assumed a mode of action by deprivation of nutritional iron; however, data here show that DFO penetrates P. carinii, causing irreversible damage, thus indicating a different mode of action. Penetration was demonstrated by showing DFO...
متن کاملS-adenosylmethionine concentrations in diagnosis of Pneumocystis carinii pneumonia.
Pneumocystis carinii is unable to synthesise S-adenosylmethionine and thus scavenges this intermediate. We aimed to test whether measurement of concentrations of this metabolic intermediate in plasma could provide a new method for rapid diagnosis of Pneumocystis carinii pneumonia (PCP). We measured S-adenosylmethionine plasma concentrations in 12 healthy controls, 16 patients with confirmed or ...
متن کاملEndemic Pneumocystis Carinii Pneumonia
The entity of interstitial plasma cell pneumonia due to Pneumocystis carinii has received increasing attention during the past 10 years. Extensive studies and reviews concerning this problem, its epidemiology and pathogenesis (Ahvenainen, 1957; Bachmann, 1954; Cahalane, 1962; Jirovec, 1 960a and b; Muller and Vietor, 1957), its clinical course and picture (Berdnikoff, 1959; Dvorak and Jirovec, ...
متن کامل[Pneumocystis carinii pneumonia].
A study is carried out in 8 infants with a diagnosis of Pneumocystis carinii pneumonia which was established through the study of histologic lung sections, and a microscopic study of protozoas. The following are some of the factors predisposing to this disease: prematurity, significant denutrition, primary immunodeficiencies, extended use of antibiotics, malignancies, and immunosuppressive trea...
