Parasitemia

12/01/2021 - "Under in vivo conditions, KBA exhibited a significant reduction in parasitemia, retarding the development of anaemia, resulting in an enhancement of the mean survival time in Plasmodium yoelii nigeriensis (chloroquine-resistant) infected mice. "
01/01/2006 - "Age effect on the clearance of parasitemia was evident in both areas, more significantly though in Gedaref (P<0.000) than Haj Yousif (P=0.043) These results add to reports in the literature, pointing to the complexity of factors that may contribute to a clinical outcome following chloroquine treatment, particularly, in this case are elements of the host immunity that are yet to be identified."
11/01/2003 - "At day 5 (D5), 57% of chloroquine-treated and 52% of N'Dribala-treated patients were cured with no detectable parasitemia (parasite density (Pd): 0) and more than 90% of whole patients were asymptomatic. "
11/01/2019 - "The objective of this study was to collect data on chloroquine resistance in French Guiana by associating a retrospective evaluation of therapeutic efficacy with an analysis of recurrent parasitemia from any patients. "
05/01/1997 - "Currently, there is no established treatment for Plasmodium vivax parasitemias that are not cured by chloroquine. "

01/01/2013 - "Co-primary endpoints included parasite clearance time (the time required for complete clearance of initial parasitemia), parasite clearance half-life (the time required for parasitemia to decrease by 50% based on the linear portion of the parasite clearance slope), and detectable parasitemia 72 hours after commencement of artesunate treatment. "
12/01/2017 - "Thus, we propose that in vivo artesunate treatment causes rapid decline in parasitemia by arresting parasite maturation and encouraging phagocyte-mediated clearance of parasitised RBCs."
12/01/2018 - "Parasitemia was cleared with artesunate (2.4 mg/kg) under a desensitization protocol. "
07/01/2019 - "Similarly, preclinical In vivo studies also signified a radical reduction in parasitemia with ~8-10-fold reduced dosage of artesunate when fortified with iron oxide nanoparticles. "
11/01/2012 - "The overall parasite clearance times were prolonged compared with the clearance times in a previous study at this site in 2006 to 2007, but this did not persist when the evaluation was limited to subjects with a comparable artesunate dose (4 mg/kg/day) and baseline parasitemia from the two studies. "

03/01/2003 - "IgG(3) levels declined sharply within 6 weeks of pharmacological clearance of parasitemia in all subjects, whereas a significant decrease in IgG(1) levels was seen only in subjects < or =19 years old. "

01/01/2021 - "IgGs purified from sera of EV-IM mice were able to opsonize tachyzoites (RH strain), and mice that received these parasites had lower parasitemias, and mortality was delayed 48 h, compared with the same results from those receiving parasites opsonized with IgG purified from NI mice. "
01/01/2020 - "Parasitemia levels were determined, and IgG titers were quantified by ELISA. "
11/01/2018 - "To test these inferences, we utilized passive immunization and knockout mice to demonstrate that ABA supplementation increases circulating levels of protective, parasite-specific IgG and requires caspase-1 to reduce parasitemia. "

09/01/2015 - "Overall there was marked decrease in parasitemia in Plasmodium berghei infected mice treated with graded doses of MJ but appears to have reduced antimalarial activity compared with CQ and AE."
01/01/2023 - "This case shows that extracorporeal support in trained hands and in a timely manner is effective when organ failure evolves rapidly to achieve stability and provide necessary time for definitive treatment, in this case rapid action antimalarials until parasitemia becomes negative. "
01/01/2018 - "The in vitro and in vivo antimalarial studies of CQ loaded NLCs showed an enhanced antimalarial efficacy of the nanoformulation with a better suppression of parasitemia and with an increased efficacy of more than 23% in comparison to pure drug. "
12/01/2023 - "In vivo, study was performed for the most potent antimalarial compound C1 to optimize the research work and found to be effectively suppressing parasitemia of Plasmodium berghei strain in the Swiss albino mice model."
11/01/2023 - "In vivo antimalarial studies using Rane's test showed a significant decrease in parasitemia by ∼70% at 1200 mg/kg doses and delayed the mortality of mice by ∼10-14 days. "

09/01/2005 - "The time to a 4-log reduction of the initial level of parasitemia (Ter) was related to the average quinine concentration from 0 to 72 h (Cav) as Ter = Tmin [1 + (C50/Cav)s], where sigmoidicity (s) is equal to 2, Tmin is the time to eradication at infinite Cav, and C50 is the value of Cav for which Ter is twice Tmin. "
09/01/2005 - "Quinine concentrations in plasma samples (five to nine per patient) were measured by liquid chromatography on days 1 to 3. Parasitemia was counted on days 0, 1, 2, 3, 4, 7, and 14. "
08/01/2005 - "Pregnant women participating in a longitudinal immuno-epidemiologic survey in Lambaréné, Gabon, and presenting with Plasmodium falciparum parasitemia at monthly blood smear examinations were offered treatment with oral 7-day quinine monotherapy according to national health guidelines. "
08/01/2005 - "The therapeutic response to quinine treatment was comparable between patients with (CS)CM and CM. In conclusion, uniquely in this setting, CM can be associated with sub-patent parasitemia; thus, a diagnostic tool more sensitive than microscopy is needed."
12/01/2001 - "The quinine dose may be reduced on day 4 of treatment when asexual parasitemia is absent. "

01/01/2017 - "There was a significant reduction in the number of treatment days (number of doses) necessary to induce parasitemia suppression with all four compounds compared to that required with benznidazole. "

03/01/1997 - "When the monkeys immunized with the antigen combination were challenged with blood-stage parasites, there was substantial protection: three of seven immunized animals self-cured and two others experienced a delayed peak of parasitemia. "
07/01/2021 - "Our study produced evidence that the fourth case, which had high parasitemia at clinical presentation, was a rare example of antigen saturation ('prozone-like effect'), leading to a false negative in the HRP2-RDT, while the fifth case was due to low parasitemia. "
01/01/2024 - "For each compound, we assess the percentages of parasitemia by smears from tail blood and the humoral response by indirect ELISA test using each compound as an antigen. "

04/01/1991 - "The serum levels of transfused antibodies were low at the peak of parasitemia, suggesting that clearance of parasites was mediated by immune responses mounted by the monkeys. "
01/12/2024 - "In contrast, the function of acquired antibodies was comparable among Hb groups and appears to be intact and sufficient to control parasitemia via opsonization and phagocytosis of IEs."

06/01/2013 - "Analysis of naturally acquired immune responses that confer protection against parasitemia and clinical disease is important to guide vaccine evaluation as well as identify immune correlates. "
04/01/1995 - "Because all five control animals had a synchronous prepatent period after challenge with live sporozoites, it was possible to quantify the protective efficacy for each vaccine formulation, even though all monkeys developed parasitemia. "
02/15/2010 - "Eleven vaccine recipients exhibited delayed onset of parasitemia. "
02/11/2016 - "In a phase IIb study, an MSP2-containing vaccine induced an immune response that reduced parasitemias in a strain-specific manner. "
