S100 calcium-binding protein B (S100B) is highly expressed in glioma cells and promotes cancer cell survival via inhibition of the p53 protein. In melanoma cells, this S100B-p53 interaction is known to be inhibited by pentamidine isethionate, an antiprotozoal agent. Thus, the aim of the present study was to evaluate the effect of pentamidine on rat C6 glioma cell proliferation, migration and ap...
Nebulised pentamidine was used to treat 30 patients with Pneumocystis carinii pneumonia. Fourteen patients (group 1) received pentamidine isethionate 4 mg/kg (six patients) or 8 mg/kg (eight patients) via a standard jet nebuliser (Acorn, system 22) with a flow rate of 8 l/min. The aerosol droplets had a mass median aerodynamic diameter of 2.6 microns (geometric standard deviation (GSD) 2.9) and...
African trypanosomiasis is a deadly neglected disease caused by the extracellular parasite Trypanosoma brucei. Current therapies are characterized by high drug toxicity and increasing drug resistance mainly associated with loss-of-function mutations in the transporters involved in drug import. The introduction of new antiparasitic drugs into therapeutic use is a slow and expensive process. In c...
We report four cases of acute reversible renal failure in patients with acquired immune deficiency syndrome who received both amphotericin B (for systemic mycoses) and pentamidine isethionate (for Pneumocystis carinii pneumonia). The concurrent use of amphotericin B with either inhaled pentamidine or trimethoprim-sulfamethoxazole did not cause significant renal impairment.
Outbreaks ofPneumocystispneumonia have been described in renal transplant recipients. Aerosolized pentamidine is frequently used for prophylaxis in this setting. We report our experience with aerosolized pentamidine use in 56 renal transplant recipients. We found high rates of adverse reactions in patients with chronic respiratory disease.
The presence of intralesional natural regulatory T cells, characterized by the expression of Foxp3 mRNA, was analyzed in patients with localized leishmaniasis due to Leishmania guyanensis infection that was unresponsive to treatment with pentamidine isethionate. Foxp3 mRNA levels were associated with unresponsiveness to treatment among patients with a lesion duration of 1 month, but this associ...
BACKGROUND There is significant variation in Amphotericin B (AMB) efficacy and relapses in antimony unresponsive visceral leishmaniasis (VL) cases over a period of time (10-15 years). Keeping in mind the above mentioned view this study was undertaken with an objective to assess the magnitude of cure and relapse rates of AMB in the treatment of antimony unresponsive VL cases. METHODS In a cont...
BACKGROUND Sleeping sickness (human African trypanosomiasis [HAT]) is a neglected tropical disease with limited treatment options that currently require parenteral administration. In previous studies, orally administered pafuramidine was well tolerated in healthy patients (for up to 21 days) and stage 1 HAT patients (for up to 10 days), and demonstrated efficacy comparable to pentamidine. MET...
STUDY OBJECTIVE There have been 15 published cases of probable pentamidine-induced torsade de pointes (TdP). A prospective analysis of this complication of therapy is valuable considering the high frequency of Pneumocystis carinii pneumonia in the AIDS population, and the role of pentamidine in its therapy. DESIGN Open, nonrandomized, prospective study of HIV-infected patients receiving intra...
The predominant mechanism of drug resistance in African trypanosomes is decreased drug uptake due to loss-of-function mutations in the genes for the transporters that mediate drug import. The role of transporters as determinants of drug susceptibility is well documented from laboratory-selected Trypanosoma brucei mutants. But clinical isolates, especially of T. b. gambiense, are less amenable t...
