A sulfone active against a wide range of bacteria but mainly employed for its actions against MYCOBACTERIUM LEPRAE. Its mechanism of action is probably similar to that of the SULFONAMIDES which involves inhibition of folic acid synthesis in susceptible organisms. It is also used with PYRIMETHAMINE in the treatment of malaria. (From Martindale, The Extra Pharmacopoeia, 30th ed, p157-8)
A sequence-related subfamily of ATP-BINDING CASSETTE TRANSPORTERS that actively transport organic substrates. Although considered organic anion transporters, a subset of proteins in this family have also been shown to convey drug resistance to neutral organic drugs. Their cellular function may have clinical significance for CHEMOTHERAPY in that they transport a variety of ANTINEOPLASTIC AGENTS. Overexpression of proteins in this class by NEOPLASMS is considered a possible mechanism in the development of multidrug resistance (DRUG RESISTANCE, MULTIPLE). Although similar in function to P-GLYCOPROTEINS, the proteins in this class share little sequence homology to the p-glycoprotein family of proteins.

Relationships between malaria prevalence and malaria-related morbidity in school children from two villages in central Africa. (1/318)

To investigate the relationship between parasite prevalence and malaria-related morbidity, we carried out a comparative study among cohorts of school children from two villages, Dienga, Gabon, and Pouma, Cameroon, both located in malaria-endemic areas. Seven to 17 year-old children attending primary schools were similarly followed-up at each site to evaluate the frequency of malaria attacks. Follow-up involved daily temperature recording (and blood smears in the case of fever) and preparation of blood smears every two weeks. In Pouma, 186 children were followed-up for six months. In Dienga, 228 children were followed-up for nine months. The mean prevalence rate of Plasmodium falciparum infections (as assessed by the blood smears) was twice as high in Pouma compared with Dienga (45.2% versus 26.8%; P < 0.0001), whereas the monthly malaria attack rate (as assessed by the daily surveillance) was twice as high in Dienga compared with Pouma (21.5% versus 41.4%; P = 0.003). The possible implication of several parameters that may differ between the two areas, such as the malaria transmission level, the economical and social status of the inhabitants, the characteristics of infecting parasite strains, and the genetic background of the population, is discussed.  (+info)

Analysis of mefloquine resistance and amplification of pfmdr1 in multidrug-resistant Plasmodium falciparum isolates from Thailand. (2/318)

Resistance to quinoline-containing compound has been associated with the Plasmodium falciparum multidrug resistance 1 (pfmdr1) gene. We analyzed wild P. falciparum isolates with high levels of chloroquine and mefloquine resistance for their macrorestriction maps of chromosome 5 and sequence of pfmdr1. Two types of chromosome 5 amplification were found. Eleven of 62 resistant isolates displayed Bgl 1 fragments larger than 100 kb. Twenty-nine isolates possessed multiple copies of the fragments. We failed to detect any amplification of this region on chromosome 5 in 22 mefloquine-resistant isolates, suggesting that other mechanisms can mediate the mefloquine-resistant phenotype. There was no direct association between pfmdr1 mutations and chloroquine sensitivity. Resistant lines could have Asn-86 and Tyr-184 or Phe-184, the predicted sequence of those chloroquine-sensitive isolates. No mutation at Asn-1042 and Asp-1246 was detected among these chloroquine-resistant isolates. Therefore, a few base substitutions in the pfmdr1 gene may not be sufficient to account for all chloroquine-resistant phenotypes.  (+info)

Factors influencing resistance to reinfection with Plasmodium falciparum. (3/318)

A treatment-reinfection study design was used to investigate the relationships between host immunologic and/or genetic factors and resistance to reinfection with Plasmodium falciparum. Sixty-one children in Gabon were enrolled in a cross-sectional study to measure the prevalence of each human plasmodial species. All were given amodiaquine for radical cure of parasites, and 40 were subsequently followed-up for 30 weeks. Successive blood smears were examined to measure the delay of reappearance in blood of asexual stages of P. falciparum parasites. Presence of infection during the cross-sectional survey was associated with male sex, non-deficient glucose-6-phosphate dehydrogenase activity, plasma interleukin-10 level, and anti-LSA-Rep antibody concentration. Resistance to reinfection was related to the presence of anti-LSA-J antibodies, and the absence of anti-LSA-Rep antibodies. Moreover, P. malariae-infected subjects were usually co-infected with P. falciparum, and were also more rapidly reinfected with P. falciparum after treatment, compared with those without P. malariae infection.  (+info)

Antibiotics for prophylaxis of Plasmodium falciparum infections: in vitro activity of doxycycline against Senegalese isolates. (4/318)

The in vitro activities of doxycycline, chloroquine, quinine, amodiaquine, artemether, pyrimethamine, and cycloguanil were evaluated against Plasmodium falciparum isolates from Senegal (Dielmo and Ndiop), using an isotopic, micro, drug susceptibility test. The 71-50% inhibitory concentration (IC50) values for doxycycline ranged from 0.7 to 108.0 microM and the geometric mean IC50 for the 71 isolates was 11.3 microM (95% confidence interval = 9.5-13.4 microM). The activity of doxycycline did not differ significantly (P = 0.0858) between the chloroquine-susceptible isolates and the chloroquine-resistant isolates. There was no in vitro correlation between the responses to doxycycline and those to artemether, chloroquine, quinine, amodiaquine, pyrimethamine, and cycloguanil, suggesting no in vitro cross-resistance among these drugs. Potency was increased by prolonged exposure. In 96-hr incubations, the activity of doxycycline was 4-5-fold more increased than in 48-hr incubations. The in vitro activity of doxycycline against intraerythrocytic stages of multidrug-resistant P. falciparum, its action against the preerythrocytic forms, the lack of correlation between the responses in vitro of P. falciparum to doxycycline and the other antimalarial drugs, and its original potential site of action are factors that favor its use as antimalarial drug.  (+info)

In vivo efficacy study of amodiaquine and sulfadoxine/ pyrimethamine in Kibwezi, Kenya and Kigoma, Tanzania. (5/318)

We conducted two randomized clinical trials to determine the in vivo efficacy of amodiaquine and sulfadoxine/pyrimethamine in treating Plasmodium falciparum malaria. Seventy-five patients under the age of 10 years in Kibwezi, Kenya, and 171 patients in Kigoma, Tanzania, were enrolled for treatment. Due to loss of eight patients in Kibwezi and 37 in Kigoma to follow-up, we used best and worst case scenarios for the parasitological response. The in vivo sensitivity of Plasmodium falciparum to amodiaquine was 75% (no loss to follow-up) in Kibwezi and ranged from 85% in the best to 65% in the worst case scenario in Kigoma. The sensitivity to sulfadoxine/pyrimethamine was 70% to 88% in Kibwezi and 65% to 89% in Kigoma. R1 resistance to amodiaquine was 22% in Kibwezi and varied from 6% in the best to 26% for the worst case scenario in Kigoma. The R1 resistance to sulfadoxine/pyrimethamine was 5% to 23% in Kibwezi and 2% to 26% in Kigoma. R2 resistance was 3% for amodiaquine and 7% for sulfadoxine/pyrimethamine in Kibwezi and 9% in Kigoma for each treatment group. There was no statistically significant difference between treatment groups at either study site, except for a slight difference in R1 resistance in the best case scenario, Kibwezi, in favour of S/P. Although both amodiaquine and sulfadoxine/pyrimethamine resistance seems to be increasing, these antimalarials are still effective in parasite clearance.  (+info)

Adaptation of a chloroquine-resistant strain of Plasmodium vivax from Indonesia to New World monkeys. (6/318)

The spread of chloroquine-resistant Plasmodium vivax from Papua New Guinea and Indonesia poses a serious health threat to areas of Southeast Asia where this species of malaria parasite is endemic. A strain of P. vivax from Indonesia was adapted to develop in splenectomized Aotus lemurinus griseimembra, Aotus vociferans, Aotus nancymai, and Saimiri boliviensis monkeys. Transmission to splenectomized Saimiri monkeys was obtained via sporozoites. Chemotherapeutic studies indicated that the strain was resistant to chloroquine and amodiaquine while sensitive to mefloquine. Infections of chloroquine-resistant P.vivax in New World monkeys should be useful for the development of alternative treatments.  (+info)

Role of extraneuronal mechanisms in the termination of contractile responses to amines in vascular tissue. (7/318)

1 The role of the uptake and release of agonist from extraneuronal sites in the termination of responses of rabbit aortic strips to amines was studied. 2 Strips were contracted with adrenaline or noradrenaline and after response plateau was reached, the muscle chambers were washed free of agonist and the relaxation in Krebs solution recorded. After inhibition of catechol-O-methyl-transferase, monoamine oxidase and neuronal uptake the relaxation rate was greatly prolonged. Evidence is provided that this very slow relaxation resulted from the accumulation of intact amine at extraneuronal sites during exposure to the agonist and its subsequent release past receptors due to a reversal of the concentration gradient after washout. 3 Pretreatment with the haloalkylamine, GD-131 (N-cyclohexylmethyl-N-ethyl-beta-chloroethylamine), an inhibitor of extraneuronal uptake, returned the slow relaxation rate after enzyme inhibition towards that of control strips. By blocking the extraneuronal transport of amines their accumulation at intracellular loci after enzyme inhibition was prevented. 4 The effects of GD-131 and 17beta-oestradiol on the relaxation rate of untreated strips contracted by adrenaline and noradrenaline confirmed that extraneuronal uptake to sites of enzymatic activity is the major mechanism terminating their action. 5 Inactivation of extraneuronal transport sites by GD-131 was prevented by protecting them with 17beta-oestradiol or normetanephrine during exposure to the haloalkylamine, pointing to a common site of action of these agents on a specific carrier system for amines. 6 Evidence is presented that the relaxation from contractions induced by histamine and 5-hydroxytryptamine also involves extraneuronal accumulation and release, probably by an uptake process which is identical to the one for catecholamines.  (+info)

"One-pot" synthesis and antimalarial activity of formamidine derivatives of 4-anilinoquinoline. (8/318)

Amodiaquine (AQ) is an antimalarial which is effective against chloroquino-resistant strains of Plasmodium falciparum but whose clinical use is severely restricted because of associated hepatotoxicity and agranulocytosis. "One-pot" synthesis of formamidines likely to be transformed into AQ derivatives is reported. Compared with AQ, the new compounds were devoid of in vitro cytotoxicity upon human embryonic lung cells and mouse peritoneal macrophages. One showed a potent in vivo activity in mice infected with P berghei. Transformation of this compound by reductive amination led to a new type of AQ derivatives that displayed an in vitro activity similar to that of AQ but did not lead to toxic quinone-imines.  (+info)

Abstract The antimalarial activities of amodiaquine, the desethyl metabolite of amodiaquine, chloroquine, and mefloquine were evaluated against 35 field isolates of Plasmodium falciparum collected from eastern Thailand, October-December 1985, to define patterns of cross-resistance among these compounds. The assay system was based on the in vitro inhibition of schizont maturation. The parasites were generally sensitive to mefloquine (mean 50%-inhibitory concentrations = 9.98 nM) and highly resistant to chloroquine (IC50 = 313 nM). The mean in vitro activity of desethylamodiaquine (67.5 nM) was approximately 3.5 times lower than that of amodiaquine (18.2 nM). There was a significant rank-order correlation between the IC50s of desethylamodiaquine and chloroquine, but not between amodiaquine and chloroquine, which suggests that the apparent cross-resistance between chloroquine and amodiaquine observed in clinical studies may be more closely related to the cross-resistance between chloroquine and the
Mutations in the Plasmodium falciparum genes pfcrt and pfmdr1 are selected by amodiaquine treatment in Africa. To examine the importance of these mutations in amodiaquine-treated Asian parasites, we determined pre- and posttreatment genotypes for amodiaquine treatment failures from a clinical trial in Afghanistan. The pfcrt codon 72 to 76 haplotype SVMNT was present in all samples tested, both before and after treatment. Amodiaquine did not clearly select for any pfmdr1 genotype, but a novel mutation, pfmdr1 N86F, was detected in four samples. We provide in vivo data to support the in vitro correlation between pfcrt SVMNT and increased resistance to the metabolite of amodiaquine.,br/, ...
Background: The development and spread of antimalarial drug resistant parasites contributes to the global impact of the disease. In vivo efficacy assessments of treatments for Plasmodium falciparum malaria are essential for ensuring effective case management. Artemisinin-based combinations have been adopted as the first-line treatment for uncomplicated P. falciparum malaria in Cameroon since 2004. Methods: A total of 177 children aged six-months to 10 years with uncomplicated mono-infected falciparum malaria were randomized (1:1) to receive artesunate/sulphadoxine-pyrimethamine (AS/SP) or artesunate/amodiaquine (AS/AQ) pediatric tablets and followed up for 28 days according to the standard World Health Organization in vivo drug efficacy monitoring protocol. The primary and secondary endpoints were PCR uncorrected and corrected cure rates, as measured by adequate clinical and parasitological response (ACPR) on day 28. Results: The PCR corrected cure rate was high, overall (88.1%, 95% CI 83.1-93.1), 85.9%

Main results: 56 studies included, mostly from Africa. Treatment allocation was adequately concealed in three trials, and unclear or inadequate in the remainder. Amodiaquine was more effective than chloroquine for parasite clearance (day 7, Peto odds ratio 4.42 (95% confidence interval 3.65 to 5.35); day 14, Peto odds ratio 6.44 (95% confidence interval (CI) 5.09 to 8.15). Comparisons with sulfadoxine/pyrimethamine were more mixed, with sulfadoxine/pyrimethamine more effective on day 28 (Peto odds ratio 0.41; 95% CI 0.28 to 0.61). No significant difference for adverse events was observed between amodiaquine and chloroquine and sulfadoxine/pyrimethamine. Reported adverse effects were minor or moderate. No life threatening events were detected ...
Abstract. Home management of malaria is recommended for prompt, effective antimalarial treatment in children less than five years of age. Compliance, safety, and effectiveness of the new fixed-dose artesunate-amodiaquine regimen used to treat suspected malaria were assessed in febrile children enrolled in a 24-month cohort study in two settings in Madagascar. Children with fever were asked to visit community health workers. Presumptive antimalarial treatment was given and further visits were scheduled for follow-up. The primary endpoint was the risk of clinical/parasitologic treatment failure. Secondary outcomes included fever/parasite clearance, change in hemoglobin levels, and frequency of adverse events. The global clinical cure rate was 98.4% by day 28 and 97.9% by day 42. Reported compliance was 83.4%. No severe adverse effects were observed. This study provides comprehensive data concerning the clinical cure rate obtained with artesunate-amodiaquine and evidence supporting the scaling up of home
CD4+ T cells play key roles in the regulation of immune responses against pathogenic infectious antigens via development into effector T helper and induced regulatory T (iTreg) cells. Particularly, CD4+CD25+Foxp3+ iTreg cells are crucial for maintaining immune homeostasis and controlling inflammatory diseases. Anti-inflammatory drugs that enhance iTreg cell generation would be effective at preventing and treating inflammatory and autoimmune diseases. In this study, we examined whether anti-malarial and anti-arthritic amodiaquine (AQ) could affect iTreg cell development. Despite the anti-proliferative activity of AQ, AQ only moderately decreased iTreg cell proliferation but substantially increased IL-2 production by iTreg cells. Furthermore, AQ dose-dependently increased iTreg cell development and significantly upregulated iTreg cell markers including CD25. Interestingly, CD25 expression was decreased at later stages of iTreg cell development but was sustained in the presence of AQ, which was ...

Artesunate-amodiaquine (AS-AQ) is one of the most widely used artemisinin-based combination therapies (ACTs) to treat uncomplicated Plasmodium falciparum malaria in Africa. We investigated the impact of different dosing strategies on the efficacy of this combination for the treatment of falciparum malaria. Individual patient data from AS-AQ clinical trials were pooled using the WorldWide Antimalarial Resistance Network (WWARN) standardised methodology. Risk factors for treatment failure were identified using a Cox regression model with shared frailty across study sites. Forty-three studies representing 9,106 treatments from 1999-2012 were included in the analysis; 4,138 (45.4%) treatments were with a fixed dose combination with an AQ target dose of 30 mg/kg (FDC), 1,293 (14.2%) with a non-fixed dose combination with an AQ target dose of 25 mg/kg (loose NFDC-25), 2,418 (26.6%) with a non-fixed dose combination with an AQ target dose of 30 mg/kg (loose NFDC-30), and the remaining 1,257 (13.8%) with a co
The study discuss the potential impact of seasonal malaria chemoprevention (SMC) on the cases of malaria, anaemia and molecular markers resistance Plasmodium falciparum malaria; and also review the mechanism of action and the effect on immunity of SMC. SMC using an efficacious drug is likely to substantially reduce cases of clinical malaria in high transmission settings. However, an increase of molecular markers could hamper rolling out SMC as a national policy.   Key words: Seasonal malaria chemoprevention impact, malaria molecular markers, review.  
Without an effective vaccine for the prevention of malaria, a fundamental component of the strategy for the control of this disease is based on prompt and effective treatment. Due to the high resistance level of Plasmodium falciparum to the most affordable drugs such as chloroquine and sulfadoxine-pyrimethamine, artemisinin-based combination therapies are presently used in many countries or are being developed for registration. One artemisinin combination therapy that is drawing a certain degree of interest is the combination of artesunate (a short half-life drug) plus amodiaquine (a long half-life drug that is presently used in loose combination in many countries). The short half-life drug achieves substantial and rapid parasite killing, while a high concentration of the long half-life drug kills off the remaining malaria parasites. In addition to the effectiveness of 3 days of treatment (rapid clearance of fever and malaria parasites) in western and central Africa, where resistance to ...

The orphan nuclear receptor Nurr1 is ascribed high potential as molecular target for Parkinsons Disease and Alzheimers Disease treatment1,2 but small molecule Nurr1 ligands and mechanistic understanding of Nurr1 modulation are scarce.. Inspired by a PDB-deposited X-ray structure of Nurr1 in complex with the arachidonic acid metabolite prostaglandin A13, we hypothesized non-steroidal anti-inflammatory drugs (NSAIDs) as Nurr1 ligands. Screening of a structurally diverse collection of NSAIDs indeed discovered several Nurr1 modulators most of which, interestingly, exhibited inverse agonism on Nurr1. Together with the previously reported Nurr1 agonist amodiaquine4, these molecules add up to a set of initial tool compounds, i.e. parecoxib, oxaprozin, amodiaquine and chloroquine, to decipher the molecular function of Nurr1.. Using this initial tool, we probed the response of the Nurr1 ligand binding domain to modulation by ligands. We observed an ability of Nurr1 agonists to stimulate homo- and ...
The mainland Chinese started studying the anti-malarial effects of the traditional anti-malarial medicine derived from the plant Artemisa anna back in the 1960s. For various reasons, including the upheavals of the Cultural Revolution, the positive results were not published internationally. When they were, in the 1990s, they were pretty much poohed-poohed by the developed world except … the pharmaceuticals who pricked up their ears and went for it big time! The plants active ingredient was Artemisin and soon the synthetic Artesunate was developed.. Artesunate is fast-acting but has a very short half-life (i.e. very quickly disappears from the blood). Amodiaquine has longer half-life. The tablets are marketed in packs of a pair a day. If there is still some residual malaria, then a second line of attack is used - the trade name Coartem, a combination of Artesunate and Lumefantrine (in turn developed from halofantrine, the basis of Halfan, which at the time of its recent development was ...
Parkinsons disease (PD), primarily caused by selective degeneration of midbrain dopamine (mDA) neurons, is the most prevalent movement disorder, affecting 1-2% of the global population over the age of 65. Currently available pharmacological treatments are largely symptomatic and lose their efficacy over time with accompanying severe side effects such as dyskinesia. Thus, there is an unmet clinical need to develop mechanism-based and/or disease-modifying treatments. Based on the unique dual role of the nuclear orphan receptor Nurr1 for development and maintenance of mDA neurons and their protection from inflammation-induced death, we hypothesize that Nurr1 can be a molecular target for neuroprotective therapeutic development for PD. Here we show successful identification of Nurr1 agonists sharing an identical chemical scaffold, 4-amino-7-chloroquinoline, suggesting a critical structure-activity relationship. In particular, we found that two antimalarial drugs, amodiaquine and chloroquine ...

BACKGROUND: The emergence of resistance against artemisinin combination treatment is a major concern for malaria control. ACTs are recommended as the rescue treatment, however, there is limited evidence as to whether treatment and re-treatment with ACTs select for drug-resistant P. falciparum parasites. Thus, the purpose of the present study is to investigate the impact of (re-)treatment using artesunate-amodiaquine (ASAQ) and artemether-lumefantrine (AL) on the selection of P. falciparum multidrug resistance-1 (Pfmdr1) alleles in clinical settings.. METHODS: P. falciparum positive samples were collected from children aged 12-59 months in a clinical trial in DR Congo and Uganda. Pfmdr1 single nucleotide polymorphisms (SNPs) analysis at codons N86Y, Y184F, and D1246Y were performed at baseline and post-treatment with either AL or ASAQ as a rescue treatment using nested PCR followed by restriction fragment length polymorphism (RFLP) assays.. RESULTS: The pre-treatment prevalence of Pfmdr1 N86 and ...
Artemether-lumefantrine (AL), dihydroartemisinin-piperaquine (DP), and amodiaquine-sulfadoxine-pyrimethamine (AQ-SP) offer excellent antimalarial efficacy but may select for parasite polymorphisms that decrease drug sensitivity. We evaluated the selection of known polymorphisms in genes encoding put …
This study showed that AL and AS-AQ remain efficacious, well-tolerated, and are safe to treat uncomplicated malaria in children from Lambaréné. However, a regular monitoring of efficacy and a study of molecular markers of drug resistance to artemisinin in field isolates is essential. Trial registrat …
Nuclear magnetic resonance (NMR) spectroscopy was used by the scientists to identify the compounds which could bind and activate Nurr1 in the brain. We all know dopamine as the chemical in the brain that generates good and pleasurable feelings. In addition to that it is also an important neurotransmitter that affects motor control and movement of muscles in the body. When a person is affected with Parkinsons disease, the production of dopamine is disrupted and it causes progressive loss of motor control. In their lab experiments, scientists found that when Nurr1 was activated in rats which had Parkinsons disease, there was a marked improvement in their behaviour and they showed no signs of suffering from the disease. Associate Professor Yoon said the team had screened about 1000 FDA-approved drugs before they found two anti-malaria drugs which showed results - Chloroquine and Amodiaquine. Associate Professor Yoon, an expert in drug discovery and design opined that their discovery brings hope ...

This study evaluated and compared the efficacy of five brands of Artemisinin Combination Therapies (ACTs); Dihydroartemisinin plus Piperaquine, Artesunate plus Amodiaquine, Artesunate plus Sulphadoxine/Pyrimethamine, Artemether plus lumefantrine and Artesunate plus mefloquine combinations in vivo in P.berghei infected swiss albino mice. The experimental animals were pre-screened to rule out infection. All drugs were administered as clinical doses for the curative test and the Mean Percentage Parasitemia level assessed daily for seven days and on day 60. The results showed that all the drugs were effective with artesunate plus amodiaquine combination being the most efficacious followed by dihydroartemisinin plus piperaquine and artesunate plus sulphadoxine plus pyrimethamine combinations followed by artesunate plus mefloquine combination and artemether plus lumefantrine combination which was the least efficacious. Results on day 60 showed increasing parasitemia levels in mice which received Artemether
Significant interest has been placed on the utility of PK parameters in predicting the treatment response. Most attention has been placed on the correlates of the AUC, as AUC represents both the duration and the degree of exposure. The accurate measurement of AUC in field studies is difficult, so recent efforts for studying the PKs of artemisinin partner drugs have focused on single day 7 drug levels (34). The rationale for this approach is that by day 7 the remaining parasites will be exposed only to the partner drug, as the rapidly eliminated artemisinin derivatives are no longer present. The level of partner drug in the days following dosing may be critical for determining both the clearance of the infection and the potential selection of drug-resistant parasites. Importantly, for the longer-acting partner drugs, the day 7 levels appear to correlate with the AUC (5), as seen for both DEAQ and LR in our study. Several studies from Thailand have examined the relationship between the day 7 ...
A study to measure adherence to artesunate and amodiaquine (AS+AQ) therapy in patients treated for uncomplicated malaria in community health centres (CHC) was conducted in Sierra Leone. Patients/caretakers were interviewed and remaining AS+AQ tablets at home after the last treatment dose were counted. Persons leaving CHCs with an AS+AQ prescription were also interviewed (exit interviews). In total, 118 patients were visited at home: 27 (22.9%) had one or more tablets left and were classed as certainly non-adherent; 34 (28.8%) were probably non-adherent [reported incorrect (n=27) or incomplete (n=7) intake]; and 57 (48.3%) were probably adherent. The main reasons for incomplete intake were sickness after one dose of AS+AQ, no food available for drug intake and forgetting to take them. For incorrect intake, reasons were vomiting after drug intake and incorrect instructions given by the CHC. Eighty-one percent of probably adherent patients reported following instructions given to them. In exit ...

BACKGROUND: Gametocytes are responsible for transmission of malaria from human to mosquito. Artemisinin combination therapy (ACT) reduces post-treatment gametocyte carriage, dependent upon host, parasite and pharmacodynamic factors. The gametocytocidal properties of antimalarial drugs are important for malaria elimination efforts. An individual patient clinical data meta-analysis was undertaken to identify the determinants of gametocyte carriage and the comparative effects of four ACTs: artemether-lumefantrine (AL), artesunate/amodiaquine (AS-AQ), artesunate/mefloquine (AS-MQ), and dihydroartemisinin-piperaquine (DP). METHODS: Factors associated with gametocytaemia prior to, and following, ACT treatment were identified in multivariable logistic or Cox regression analysis with random effects. All relevant studies were identified through a systematic review of PubMed. Risk of bias was evaluated based on study design, methodology, and missing data. RESULTS: The systematic review identified 169 published
The World Health Organization recommends the use of artemisinin-based combination therapy (ACT) to treat uncomplicated malaria for the control of malaria across the world. There are several types of ACT used across malaria-endemic countries, yet there is little information about preferences and adherence practices regarding different types of ACT. The objective of this study was to evaluate levels of adherence to two types of ACT, artemether-lumefantrine (AL) and artesunate + amodiaquine (ASAQ), for the treatment of uncomplicated malaria among prescribers and patients in Guinea in 2016. The study included a review of records of malaria patients and three health-facility, cross-sectional surveys. Patients diagnosed with uncomplicated malaria and prescribed ACT (n = 1830) were recruited and visited in their home after receiving the medication and administered a questionnaire regarding ACT adherence. Prescribers (n = 115) and drug dispensers (n = 43) were recruited at the same public health facilities and

There is hope that none of the above-mentioned concerns will be substantiated in larger, upcoming trials. What can be done besides hoping? Attempts to regain efficacy of artemisinins by increasing dose were disappointing [24] and since only fixed-dose combinations are licensed, increased partner drug dosing could be associated with increased toxicity and adherence issues. Extending the course of routine 3-day treatment to 5 or 7 days was successful, associated with a cure rate of 98% in western Cambodia, the epicentre of drug resistance [25]. The cost of such compromised regimens will increase, while adherence could decrease. Practitioners in Vietnam have instead empirically started to add mefloquine to the current DHA-piperaquine first-line treatment. There appears to be an inverse susceptibility between piperaquine and mefloquine. A similar inverse susceptibility between co-artemether (artemether/lumefantrine) and amodiaquine could be exploited as stopgap measure in Africa [26]. Mefloquine did ...
HIV and malaria are two of the most pernicious diseases facing developing countries. Malaria affects 300 to 500 million individuals annually in developing countries and it is estimated that 25.8 million people in Africa live with HIV. Current therapy recommended by the World Health Organization includes the use of artemisinin derivatives, such as artesunate and artemether. To minimize the risk of resistance, these drugs are used in combination with older drugs with longer half-lives including amodiaquine and lumefantrine.. Treatment of malaria is further complicated by the increasing availability of antiretroviral (ARV) medications for HIV in that clinically important drug-drug interactions may occur in co-infected patients. Protease inhibitor (e.g. lopinavir and ritonavir) and non-nucleoside reverse transcriptase (e.g. efavirenz) based treatment commonly affects pharmacokinetic exposure of drugs metabolized by cytochrome P450 (CYP) metabolic pathways.. Artemether is metabolized by the CYP3A4 to ...

Data from trials published between 1982 and July 2016 were included. A total of 177 trials met the inclusion criteria. 35,448 participants received quinoline antimalarials in these trials, of which 18,436 participants underwent ECG evaluation. Subjects with co-medication use or comorbidities including cardiovascular disease were excluded from the majority of trials. Dihydroartemisinin-piperaquine was the drug most studied (5083 participants). Despite enormous use over the past 60 years, only 1076, 452, and 150 patients had ECG recordings reported in studies of chloroquine, amodiaquine, and primaquine respectively. Transiently high concentrations of quinine, quinidine, and chloroquine following parenteral administration have all been associated with hypotension, but there were no documented reports of death or syncope attributable to a cardiovascular cause, nor of electrocardiographic recordings of ventricular arrhythmia in these trials. The large volume of missing outcome information and the ...

Artemisinin-based combination therapy (ACT) is used extensively as first-line treatment for uncomplicated falciparum malaria. There has been no rigorous assessment of the potential for racial/ethnic differences in the pharmacokinetic properties of ACTs that might influence their efficacy. Areas covered: A comprehensive literature search was performed that identified 72 publications in which the geographical origin of the patients could be ascertained and the key pharmacokinetic parameters maximum drug concentration (Cmax), area under the plasma concentration-time curve (AUC) and elimination half-life (t½β) were available for one or more of the five WHO-recommended ACTs (artemether-lumefantrine, artesunate-amodiaquine, artesunate-mefloquine, dihydroartemisinin-piperaquine and artesunate-sulfadoxine-pyrimethamine ...
Seasonal malaria chemoprevention (SMC) was recommended in 2012 for young children in the Sahel during the peak malaria transmission season. Children are given a single dose of sulfadoxine/pyrimethamine combined with a 3-day course of amodiaquine, once a month for up to 4 months. Roll-out and scale-up of SMC has been impressive, with 12 million children receiving the intervention in 2016. There is evidence of its overall benefit in routine implementation settings, and a meta-analysis of clinical trial data showed a 75% decrease in clinical malaria compared to placebo. SMC is not free of shortcomings. Its target zone includes many hard-to-reach areas, both because of poor infrastructure and because of political instability. Treatment adherence to a 3-day course of preventive treatment has not been fully documented, and could prove challenging. As SMC is scaled up, integration into a broader, community-based paradigm which includes other preventive and curative activities may prove beneficial, both ...
Over-diagnosis of malaria among African children results in mismanagement of non-malaria infections. Limited laboratory capacity makes it difficult to implement policies that recommend pre-treatment confirmation of infections so a new approach with a package for on-the-spot management of fevers was evaluated. Febrile children presenting to outpatient clinic were randomized to receive either a test-treat package (history with clinical examination; point-of-care tests; choice of artesunate-amodiaquine, co-amoxiclav and/or paracetamol) or routine outpatient care in a secondary health care facility in Kumasi, Ghana. A diagnosis of malaria, bacterial, viral or mixed malarial and bacterial infections was made using pre-defined criteria. Outcome was resolution of all symptoms including fever on day 7. The median age of the patients was 37.5 months (IQR: 19 to 66 months), with 56.7% being males. Compared to routine care the test-treat package resulted in less diagnoses of malaria, (37.2% vs 46.2%, p = ...
Seven patients developed hepatitis after receiving amodiaquine for malaria prophylaxis for 4 to 15 weeks. Four patients had a minor form of hepatitis: jaundice was mild or absent, serum aminotransferase levels were moderately increased, and recovery was prompt. Three patients had a severe form: jaundice was intense, serum aminotransferase levels were markedly increased, jaundice persisted for 3 to 6 months, and liver tests were still abnormal 7 to 27 months after the onset of hepatitis. In two patients, serum aminotransferase levels increased promptly after readministration of the drug, which is consistent with an immunoallergic mechanism for amodiaquine-induced hepatitis. ...

... is a benzamide,[12] derivative of morpholine,[103] which acts pharmacologically as a selective, reversible inhibitor of monoamine oxidase A (RIMA),[9] a type of monoamine oxidase inhibitor (MAOI), and increases levels of norepinephrine (noradrenaline), dopamine, and especially serotonin.[104][105] in neuronal cells as well as in synaptic vesicles; extracellular levels also increase which results in increased monoamine receptor stimulation and suppression of REM sleep, down regulation of 3-adrenoceptors. A single 300 mg dose of moclobemide inhibits 80% of monoamine oxidase A (MAO-A) and 30% of monoamine oxidase B (MAO-B), blocking the decomposition of norepinephrine, serotonin and, to a lesser extent, dopamine. There is also some evidence pointing towards moclobemide possessing neuroprotective properties.[8] There is no cumulative effect of moclobemide centrally when taken long-term.[8] With long-term use of moclobemide, there is a significant down-regulation of B-adrenoceptors.[8] ...

A deficiency of tyrosine hydroxylase leads to impaired synthesis of dopamine as well as epinephrine and norepinephrine. It is represented by a progressive encephalopathy and poor prognosis. Clinical features include dystonia that is minimally or nonresponsive to levodopa, extrapyramidal symptoms, ptosis, miosis, and postural hypotension. This is a progressive and often lethal disorder, which can be improved but not cured by levodopa.[39] Response to treatment is variable and the long-term and functional outcome is unknown. To provide a basis for improving the understanding of the epidemiology, genotype/phenotype correlation and outcome of these diseases their impact on the quality of life of patients, and for evaluating diagnostic and therapeutic strategies a patient registry was established by the noncommercial International Working Group on Neurotransmitter Related Disorders (iNTD).[40] Additionally alterations in the tyrosine hydroxylase enzyme activity may be involved in disorders such as ...

... is a non-selective and irreversible inhibitor of the enzyme monoamine oxidase (MAO). It inhibits both of the respective isoforms of MAO, MAO-A and MAO-B, and does so almost equally, with slight preference for the former. By inhibiting MAO, phenelzine prevents the breakdown of the monoamine neurotransmitters serotonin, melatonin, norepinephrine, epinephrine, and dopamine, as well as the trace amine neuromodulators such as phenethylamine, tyramine, octopamine, and tryptamine. This leads to an increase in the extracellular concentrations of these neurochemicals and therefore an alteration in neurochemistry and neurotransmission. This action is thought to be the primary mediator in phenelzine's therapeutic benefits. Phenelzine and its metabolites also inhibit at least two other enzymes to a lesser extent, of which are alanine transaminase (ALA-T),[21] and γ-Aminobutyric acid transaminase (GABA-T),[22] the latter of which is not caused by phenelzine itself, but by a phenelzine metabolite ...
... is an alkaloid found in Corydalis (Papaveraceae) and Dicentra, plants in the family Fumariaceae that can cause fatal poisoning in sheep and cattle.[citation needed] It has been shown to act as an acetylcholinesterase inhibitor,[1] and inhibits biosynthesis of dopamine via inhibition of the enzyme tyrosine hydroxylase.[2][3] Like apomorphine, it is reported to be an inhibitor of amyloid beta protein (Aβ) fiber formation, whose presence is a hallmark of Alzheimer's disease (AD). Bulbocapnine is thus a potential therapeutic under the amyloid hypothesis.[4] According to the Dorlands Medical Dictionary, it "inhibits the reflex and motor activities of striated muscle. It has been used in the treatment of muscular tremors and vestibular nystagmus".[5] A psychiatrist at Tulane University named Robert Heath carried out experiments on prisoners at the Louisiana State Penitentiary using bulbocapnine to induce stupor.[6] This work at Tulane inspired, and was continued parallel to, experiments ...

... was also the first drug used for treatment of malaria.[40] Quinine was used as a muscle relaxant by the Quechua, who are indigenous to Peru, Bolivia and Ecuador, to halt shivering due to low temperatures.[41] The Quechuas would mix the ground bark of cinchona trees with sweetened water to offset the bark's bitter taste, thus producing tonic water.[citation needed] The Jesuits were the first to bring cinchona to Europe. The Spanish were aware of the medicinal properties of cinchona bark by the 1570s or earlier: Nicolás Monardes (1571) and Juan Fragoso (1572) both described a tree that was subsequently identified as the cinchona tree and whose bark was used to produce a drink to treat diarrhea.[42] Quinine has been used in unextracted form by Europeans since at least the early 17th century. It was first used to treat malaria in Rome in 1631. During the 17th century, malaria was endemic to the swamps and marshes surrounding the city of Rome. Malaria was responsible for the deaths of ...

Coartem is provided without profit to developing countries using grants from the Global Fund to Fight AIDS, Tuberculosis and Malaria, US President's Malaria Initiative along with other donors. Novartis has lowered the price of Coartem by 50% since 2001, increasing access to patients around the world. The first significant price reduction occurred in 2006, when the price of Coartem decreased from an average of US $1.57 to US $1.00. In 2006, due to an improved supply situation for the natural ingredient artemisinin, Novartis was able to undertake the pharmaceutical industry's most aggressive manufacturing scale-up of its kind from 4 million treatments in 2004 to 62 million treatments in 2006.[citation needed] Novartis and its partners invested heavily in expanding production capacity at their facilities in China, and Suffern, New York. This increase in production capacity ensured that supplies of Coartem met demand which enabled Novartis to further decrease the price of Coartem. In April 2008, ...
... is widely used to treat infections of Giardia in dogs, cats, and other companion animals, although it does not reliably clear infection with this organism and is being supplanted by fenbendazole for this purpose in dogs and cats.[53] It is also used for the management of chronic inflammatory bowel disease in cats and dogs.[54] Another common usage is the treatment of systemic and/or gastrointestinal clostridial infections in horses. Metronidazole is used in the aquarium hobby to treat ornamental fish and as a broad-spectrum treatment for bacterial and protozoan infections in reptiles and amphibians. In general, the veterinary community may use metronidazole for any potentially susceptible anaerobic infection. The U.S. Food and Drug Administration (FDA) suggests it only be used when necessary because it has been shown to be carcinogenic in mice and rats, as well as to prevent antimicrobial resistance.[55][56] ...

... is primarily used to prevent relapse of malaria due to Plasmodium vivax and Plasmodium ovale.[9] It eliminates hypnozoites, the dormant liver form of the parasite,[10] after the organisms have been cleared from the bloodstream.[9] If primaquine is not administered to patients with proven P. vivax or P. ovale infection, a very high likelihood of relapse exists for weeks or months (sometimes years).[9] Use in combination with quinine or chloroquine each of which is very effective at clearing P. vivax from blood, improves outcomes; they appear to also potentiate the action of primaquine.[11] As of 2016, the Centers for Disease Control and Prevention recommended the use of primaquine for primary prophylaxis prior to travel to areas with a high incidence of P. vivax, and for terminal prophylaxis (anti-relapse therapy) after travel.[4] A single dose of primaquine has rapid and potent ability to kill gametocytes (stage V) of P. falciparum and P. vivax in blood; it also kills asexual ...
... was formulated at Walter Reed Army Institute of Research (WRAIR) in the 1970s shortly after the end of the Vietnam war. Mefloquine was number 142,490 of a total of 250,000 antimalarial compounds screened during the study.[3] Mefloquine was the first Public-Private Venture (PPV) between the US Department of Defense and a pharmaceutical company. WRAIR transferred all its phase I and phase II clinical trial data to Hoffman LaRoche and Smith Kline. FDA approval as a treatment for malaria was swift. Most notably, phase III safety and tolerability trials were skipped.[3] The drug was first approved and sold on a commercial basis in Switzerland in 1985.[31] However, mefloquine was not approved by the FDA for prophylactic use until 1989. This approval was based primarily on compliance, while safety and tolerability were overlooked.[3] Because of the drug's very long half-life, the Centers for Disease Control originally recommended a mefloquine dosage of 250 mg every two weeks; however, this ...
