BACKGROUND: An intensive effort to control malaria in Zimbabwe has produced dramatic reductions in the burden of the disease over the past 13 years. The successes have prompted the Zimbabwe's National Malaria Control Programme to commit to elimination of malaria. It is critical to analyse the changes in the morbidity trends based on surveillance data, and scrutinize reorientation to strategies for elimination. METHODS: This is a retrospective study of available Ministry of Health surveillance data and programme reports, mostly from 2003 to 2015...

BACKGROUND: Dried leaf Artemisia annua (DLA) has shown efficacy against Plasmodium sp. in rodent studies and in small clinical trials. Rodent malaria also showed resiliency against the evolution of artemisinin drug resistance. PURPOSE: This is a case report of a last resort treatment of patients with severe malaria who were responding neither to artemisinin combination therapy (ACT) nor i.v. artesunate. STUDY DESIGN: Of many patients treated with ACTs and i...

BACKGROUND: Many reviews aim to compare numerous treatments and report results stratified by subgroups (e.g. by disease severity). In such cases, a network meta-analysis model including treatment by covariate interactions can estimate the relative effects of all treatment pairings for each subgroup of patients. Two key assumptions underlie such models, consistency of treatment effects and consistency of the regression coefficients for the interactions. Consistency may differ depending on the covariate value at which consistency is assessed...

Iron is an essential micronutrient for bacteria, fungi, and humans; as such, each has evolved specialized iron uptake systems to acquire iron from the extracellular environment and a complex 'tug of war' has evolved between human hosts and pathogenic microorganisms in the battle for this vital nutrient. In humans, sequestration (hiding) of iron from invading pathogens is often successful; however, many pathogens have evolved mechanisms to circumvent this approach. Clinically, controversy continues whether iron overload or administration of iron results in an increased risk of infection...

Artemisinin-based combination therapies are recommended as first-line agents for treating uncomplicated Plasmodium falciparum malaria. Ferroquine, a 4-aminoquinolone, is a novel long-acting combination partner for fast-acting drugs like artesunate (AS). We did a small phase 2a, multicenter, open-label, safety-focused dose-ranging randomized study of ferroquine at three African hospitals: two Gabonese and one Kenyan. We recruited adult men with symptomatic uncomplicated P. falciparum monoinfection. Four escalating doses of ferroquine (100, 200, 400, and 600 mg) were assessed in sequence, versus an amodiaquine comparator...

Artemisinin-resistant malaria has not been reported from Africa, but resistance can possibly spread from Asia or arise independently in Africa. The emergence of artemisinin resistance in Africa can be monitored by molecular assay of Kelch 13 (K13) propeller sequences. A total of 251 archived DNA samples of Plasmodium falciparum isolates collected in 2002, 2003, and 2006 in Yaounde, Cameroon, and 47 samples collected in 2006 and 2013 in Abidjan, Côte d'Ivoire, were analyzed for K13-propeller sequence polymorphism...

BACKGROUND: Malaria is one of the most common causes of morbidity and mortality in our part of the world. Artemether-Lumefantrine (AL) Combination therapy is widely used for the treatment of malaria both in outpatients and inpatients hospital settings. Some of the previous anti-malarial were associated with prolongation of QTc interval. Similar query was raised about AL therapy. This study was conducted to determine the risk of QTc interval prolongation in ECG of patients with Falciparum malaria using oral Artemether-Lumefantrine (AL) combination therapy...

Antimalarial therapy during pregnancy poses important safety concerns due to potential teratogenicity and maternal physiological and biochemical changes during gestation. Piperaquine (PQ) has gained interest for use in pregnancy in response to increasing resistance towards sulfadoxine-pyrimethamine in sub-Saharan Africa. Co-infection with HIV is common in many developing countries, however, little is known about the impact of anti-retroviral (ARV) mediated drug-drug interaction (DDI) on PQ pharmacokinetics during pregnancy...

INTRODUCTION: Prior studies have shown an association between the onset of hepatonephritis and the use of arteminisin-based combination therapy (ACT) during the treatment of uncomplicated malaria. The objective of this study was to identify the risk factors of hepatonephritis occurrence because of the uncertainty regarding the appearance and the aggravation of this syndrome. METHODS: A case-non case study was carried out on 428 notifications of pharmacovigilance extracted from the database of the clinical pharmacology department of the teaching hospital of Cocody from 2008 to 2012...

Pulmonary complications, including acute respiratory distress syndrome (ARDS), are well described in P. falciparum (PF) and to a lesser extent in other malaria species. In non-endemic areas, malaria diagnosis may be overlooked; if a thorough travel history is not obtained on all patients with acute febrile illness. Three patients with malaria associated respiratory distress were admitted to our intensive care unit. The diagnosis was delayed; however, all patients received artesunate and intensive therapy with a satisfactory outcome...

BACKGROUND: We evaluated albumin cobalt binding (ACB) assay also known as Ischaemia Modified Albumin (IMA) assay as a prognostic marker for severe malaria in a medical college setting. METHODS: Consecutive adult patients admitted with both vivax and falciparum malaria were evaluated with ACB assay at the time of admission. Detailed work up and individual patient directed management were instituted in addition to immediate artemisin based antimalarial therapy. RESULTS: 100 consecutive patients (50 with vivax and 50 with falciparum malaria) were evaluated...

Plasmodium falciparum may cause serious and sometimes even fatal cerebral malaria. Cerebral malaria is a disease characterized by alterations in consciousness and epileptic attacks; therefore, it requires a rapid evaluation and quick intervention. It may progress to a fatal outcome despite administering targeted therapeutic interventions. There are studies indicating that erythrocyte exchange (erythrocytapheresis) can be a treatment modality for managing severe malaria patients. In this case report, the successful management of a cerebral malaria patient by the combination of antimalarial drug therapy and erythrocyte exchange is presented...

Resistance to most antimalarial drugs has spread from Southeast Asia to Africa. Accordingly, new therapies to use with artemisinin-based combination therapy (triple ACT) are urgently needed. Proveblue, a methylene blue preparation, was found to exhibit antimalarial activity against Plasmodium falciparum strains in vitro. Proveblue has synergistic effects when used in combination with dihydroartemisinin, and has been shown to significantly reduce or prevent cerebral malaria in mice. The objectives of the current study were to evaluate the in vitro baseline susceptibility of clinical field isolates to Proveblue, compare its activity with that of other standard antimalarial drugs and define the patterns of cross-susceptibility between Proveblue and conventional antimalarial drugs...

Artemisinin (ART)-based combination therapies are the most efficacious treatment of uncomplicated Plasmodium falciparum malaria. Alarmingly, P. falciparum strains have acquired resistance to ART across much of Southeast Asia. ART creates widespread protein and lipid damage inside intraerythrocytic parasites, necessitating macromolecule degradation. The proteasome is the main engine of Plasmodium protein degradation. Indeed, proteasome inhibition and ART have shown synergy in ART-resistant parasites. Moreover, ubiquitin modification is associated with altered parasite susceptibility to multiple antimalarials...

BACKGROUND: The World Health Organisation (WHO) recommends parasitological diagnosis of malaria before treatment, but use of malaria rapid diagnostic tests (mRDTs) by community health workers (CHWs) has not been fully tested within health services in south and central Asia. mRDTs could allow CHWs to diagnose malaria accurately, improving treatment of febrile illness. METHODS: A cluster randomised trial in community health services was undertaken in Afghanistan. The primary outcome was the proportion of suspected malaria cases correctly treated for polymerase chain reaction (PCR)-confirmed malaria and PCR negative cases receiving no antimalarial drugs measured at the level of the patient...

Khairul M F Mustaffa, Janet Storm, Megan Whittaker, Tadge Szestak, Alister G Craig
BACKGROUND: Sequestration of parasitized red blood cells from the peripheral circulation during an infection with Plasmodium falciparum is caused by an interaction between the parasite protein PfEMP1 and receptors on the surface of host endothelial cells, known as cytoadherence. Several lines of evidence point to a link between the pathology of severe malaria and cytoadherence, therefore blocking adhesion receptors involved in this process could be a good target to inhibit pRBC sequestration and prevent disease...

BACKGROUND: The malaria burden has decreased significantly in recent years in Africa through the widespread use of artemisinin-based combination therapy (ACT) and long-lasting insecticide-treated nets (LLINs). However, the occurrence of malaria resurgences, the loss of immunity of exposed populations constitute among other factors, serious concerns about the future of malaria elimination efforts. This study investigated the evolution of malaria morbidity in Dielmo (Senegal) before and after the implementation of LLINs...
