Evidence is presented for the interaction of X irradiation, slightly toxic levels of chloroquine, and mild hyperthermia in the inactivation of colony-forming ability in asynchronous HeLa cells. A three-way interaction was observed which resulted in the potentiation of radiation-induced lethality.
Antibody-mediated 17D yellow fever virus infection of a murine macrophage-like cell line, P388D1, was not inhibited by concentrations of cytochalasin B which did inhibit phagocytosis of antibody-coated sheep red blood cells. Chloroquine did not affect antibody-mediated enhancement of viral growth
To test the hypothesis that radiosensitization by combined mild hyperthermia and chloroquine may be increased by the presence of melanin in treated cells, Cloudman melanotic mouse melanoma S91/6 cells, and the amelanotic S91/amel cells were incubated during a 3 h post-irradiation period with 0.03 mM
When present during the whole infective cycle, the lysosomotropic drug, chloroquine, inhibited cytopathic changes and production of African swine fever virus (ASFV) in Vero cells. This inhibition decreased when the drug was added from 1 h to 4 h after infection. Chloroquine had no effect on the
Following widespread chloroquine (CQ) resistance, sulfadoxine plus pyrimethamine (SP) is now the first line antimalarial drug in a number of African countries including Tanzania. Unlike CQ, SP has no antipyretic effects, a feature that might delay fever clearance, and by acting on late stage
The antimalarial agent chloroquine (CQ) inhibits DNA and RNA polymerase and interferes with lysosomal function. We sought to determine if these properties make chloroquine effective as a hyperthermia sensitizer. B16F10 melanoma cells were treated for 180 min at 37 or 41 degrees C with 0.005 mM CQ,
Weekly oral chloroquine prophylaxis for malaria has been associated with impaired antibody response to intradermal rabies vaccination. Experimental data indicate that chloroquine may inhibit yellow fever virus in vitro, yet there has been no clinical evidence to suggest that antibody response to
OBJECTIVE
Chloroquine induces a severe generalized pruritus, in predisposed Black African patients, during treatment of malaria fever, and also in some Caucasian patients treated for rheumatological diseases. We have previously shown that chloroquine may release endogenous opioids and/or interact
A number of reports suggest that hyperthermia is an effective adjunctive treatment modality in management of neural crest tumors. Recent studies have demonstrated a synergistic effect of induced hyperthermia when coupled with chloroquine in an in vitro model. This study examines the effect of
To establish the effects of chloroquine on kidney function we monitored renal parameters in age and sex matched control subjects and patients who presented with acute transient fever. The patients were immediately treated with chloroquine diphosphate in the recommended dosage. Blood samples for
Endocarditis is a rare but severe complication of Q fever, an infectious disease caused by the intracellular pathogen Coxiella burnetii. Heart involvement is the most common clinical presentation of chronic Q fever, and it occurs almost invariably in patients with previous valvular disease or
Autophagy is found to serve as a surviving mechanism for cancer cells. Inhibiting autophagy has been considered as an adjuvant anti-cancer strategy. In this study, we investigated the anti-tumor effect of combining pulsed-wave ultrasound hyperthermia (pUH) enhanced PEGylated liposomal doxorubicin
Crimean-Congo hemorrhagic virus (CCHFV) causes hemorrhagic fever with high case mortality rates and is endemic in south-eastern Europe, Africa, and Asia. The limited catalog of specific treatment, highlight the necessity to look for additional therapeutic solutions. Previous experiments suggested
BACKGROUND
In the Global Strategy for Malaria Control, one of the basic elements is early detection and prompt treatment of malaria cases, especially in areas where health care facilities are inadequate. Establishing or reviving the existing drug distribution centers (DDC) at the peripheral levels
OBJECTIVE
Chloroquine treatment of malaria fever, results in a generalized pruritus of unknown mechanism in up to 60% of adult Africans, by contrast pruritus is unusual in Caucasians following chloroquine use.
METHODS
We conducted a double-blind, randomized, parallel group study to examine and
