Martensson, B. Ngasala, S. Dahlstrom, N. Lindegardh, A. Annerberg, Zul Premji, A. Farnert, P. Gil, A. Bjorkman, M. Ashton

Pathology, East Africa

The combination of artemether (ARM) and lumefantrine is currently the first-line treatment of uncomplicated falciparum malaria in mainland Tanzania. While the exposure to lumefantrine has been associated with the probability of adequate clinical and parasitological cure, increasing exposure to artemether and the active metabolite dihydroartemisinin (DHA) has been shown to decrease the parasite clearance time. The aim of this analysis was to describe the pharmacokinetics and pharmacodynamics of artemether, dihydroartemisinin, and lumefantrine in African children with uncomplicated malaria. In addition to drug concentrations and parasitemias from 50 Tanzanian children with falciparum malaria, peripheral parasite densities from 11 asymptomatic children were …

In Vivo Selection Of Plasmodium Falciparum Parasites Carrying The Chloroquine-Susceptible Pfcrt K76 Allele After Treatment With Artemether-Lumefantrine In Africa, C. Sisowath, I. Petersen, M.I. Veiga, A. Martensson, Zul Premji, A. Bjorkman, D.A. Fidock, J.P. Gil

Pathology, East Africa

Background: Artemether-lumefantrine (AL) is a major and highly effective artemisinin-based combination therapy that is becoming increasingly important as a new first-line therapy against Plasmodium falciparum malaria. However, recrudescences occurring after AL treatment have been reported. Identification of drug-specific parasite determinants that contribute to treatment failures will provide important tools for the detection and surveillance of AL resistance.

Methods: The findings from a 42-day follow-up efficacy trial in Tanzania that compared AL with sulfadoxinepyrimethamine (SP) were analyzed to identify candidate markers for lumefantrine tolerance/resistance in the chloroquine resistance transporter gene (pfcrt) and multidrug resistance gene 1 (pfmdr1). The findings were corroborated …

Menendez

Pathology, East Africa

Background: Intermittent preventive treatment (IPT) is a promising strategy for malaria control in infants. We undertook a pooled analysis of the safety and efficacy of IPT in infants (IPTi) with sulfadoxine-pyrimethamine in Africa. Methods: We pooled data from six double-blind, randomised, placebo-controlled trials (undertaken one each in Tanzania, Mozambique, and Gabon, and three in Ghana) that assessed the efficacy of IPTi with sulfadoxine-pyrimethamine. In all trials, IPTi or placebo was given to infants at the time of routine vaccinations delivered by WHO's Expanded Program on Immunization. Data from the trials for incidence of clinical malaria, risk of anaemia (packed-cell volume <25% or haemoglobin <80 g/L), and incidence of hospital admissions and adverse events in infants up to 12 months of age were reanalysed by use of standard outcome definitions and time periods. Analysis was by modified intention to treat, including all infants who received at least one dose of IPTi or placebo. Findings: The six trials provided data for 7930 infants (IPTi, n=3958; placebo, n=3972). IPTi had a protective efficacy of 30·3% (95% CI 19·8-39·4, p<0·0001) against clinical malaria, 21·3% (8·2-32·5, p=0·002) against the risk of anaemia, 38·1% (12·5-56·2, p=0·007) against hospital admissions associated with malaria parasitaemia, and 22·9% (10·0-34·0, p=0·001) against all-cause hospital admissions. There were 56 deaths in the IPTi group compared with 53 in the placebo group (rate ratio 1·05, 95% CI 0·72-1·54, p=0·79). One death, judged as possibly related to IPTi because it occurred 19 days after a treatment dose, was subsequently attributed to probable sepsis. Four of 676 non-fatal hospital admissions in the IPTi group were deemed related to study treatment compared with five of 860 in the placebo group. None of three serious dermatological adverse events in the IPTi group were judged related to study treatment compared with one of 13 in the placebo group. Interpretation: IPTi with sulfadoxine-pyrimethamine was safe and efficacious across a range of malaria transmission settings, suggesting that this intervention is a useful contribution to malaria control.

Umeh, S. Owusu-Agyei, F. Esamai, E.U. Ezedinachi, S. Oguche, S. Borrmann, A. Sowunmi, S. Duparc, P.L. Kirby, A. Pamba, L. Kellam, R. Guiguemde, B. Greenwood, S.A. Ward, P.A. Winstanley

Pathology, East Africa

Background: Chlorproguanil-dapsone-artesunate (CDA) was developed as an affordable, simple, fixed-dose artemisinin-based combination therapy for use in Africa. This trial was a randomized parallel-group, double-blind, double-dummy study to compare CDA and artemether-lumefantrine (AL) efficacy in uncomplicated Plasmodium falciparum malaria and further define the CDA safety profile, particularly its hematological safety in glucose-6-phosphate dehydrogenase (G6PD) -deficient patients. Methods and Findings: The trial was conducted at medical centers at 11 sites in five African countries between June 2006 and August 2007. 1372 patients (≥1 to <15 years>old, median age 3 years) with acute uncomplicated P. falciparum malaria were randomized (2:1) to receive CDA 2/2.5/4 …

Coartem°: The Journey To The Clinic, Zul Premji

Pathology, East Africa

Artemisinin, from which the artemether component of Coartem° (artemether/lumefantrine, AL) is derived, is obtained from the plant sweet wormwood (Artemisia annua) which has been used for over 2,000 years as a Chinese herbal remedy. Artemisinin was first identified by Chinese researchers as the active anti-malarial constituent of A. annua and its derivatives were found to be the most potent of all anti-malarial drugs. Artemether acts rapidly, reducing the infecting parasite biomass by approximately 10,000-fold per asexual life cycle. Lumefantrine, the other active constituent of AL, acts over a longer period to eliminate the residual 100-100,000 parasites that remain after artemether …

Primary Health Care Providers’ Knowledge And Practices On Asthma Management Within Dar Es Salaam Region Health Facilities, John C. Rwegasha

Master of Medicine in Family Medicine

Background: Asthma is a common chronic health problem worldwide with considerable variation in the way it is managed. In the sub- Saharan Africa there is substantial gaps in asthma care; countries like Tanzania with inadequate health care structure are lagging far behind in both correct diagnosis and management of asthma. The increasing prevalence of asthma within populations is attributed to a number of the following factors; Patient behavior, Health service structure and access, Environmental factors and Provider's knowledge and practices. There is lack of required standard asthma care under provider's factors, hindering effective control of the disease. This could be …

Willingness And Ability To Pay For Artemisinin-Based Combination Therapy In Rural Tanzania, E.C. Saulo, B.C. Forsberg, Zul Premji, S.M. Montgomery, A. Bjorkman

Pathology, East Africa

Background: The aim of this study was to analyse willingness to pay (WTP) and ability to pay (ATP) for ACT for children below five years of age in a rural setting in Tanzania before the introduction of artemisinin-based combination therapy (ACT) as first-line treatment for uncomplicated malaria. Socio-economic factors associated with WTP and expectations on anti-malaria drugs, including ACT, were also explored.

Methods: Structured interviews and focus group discussions were held with mothers, household heads, health-care workers and village leaders in Ishozi, Gera and Ishunju wards in north-west Tanzania in 2004. Contingent valuation method (CVM) was used with "take-it-or-leave- it" …

Hiv, Hepatitis B And Hepatitis C Coinfection In Kenya, Reena Shah, Jane Karuru, Mark Nelson, Justin Stebbing

Internal Medicine, East Africa

There are few data regarding hepatitis and HIV coinfection in Africa. In 378 HIV seropositive individuals in Nairobi, 23 (6%) were hepatitis B virus (HBV) and HIV coinfected, four (1%) were hepatitis C virus (HCV) and HIV coinfected and one patient was infected with all three viruses. Coinfected individuals were more likely to be men and older; a lack of HBV vaccination was a risk factor for HIV/HBV coinfection (PU0.001) and tenofovir containing regimens appeared most effective at reducing HBV viral load.

Ngasala, M. Mubi, M. Warsame, M.G. Petzold, A.Y. Massele, L.L. Gustafsson, G. Tomson, Zul Premji, A. Bjorkman

Pathology, East Africa

Background: Prescribing antimalarial medicines based on parasite confirmed diagnosis of malaria is critical to rational drug use and optimal outcome of febrile illness. The impact of microscopy-based versus clinical-based diagnosis of childhood malaria was assessed at primary health care (PHC) facilities using a cluster randomized controlled training intervention trial.

Methods: Sixteen PHC facilities in rural Tanzania were randomly allocated to training of health staff in clinical algorithm plus microscopy (Arm-I, n = 5) or clinical algorithm only (Arm-II, n = 5) or no training (Arm-III, n = 6). Febrile under-five children presenting at these facilities were assessed, treated and scheduled …

The Content Of African Diets Is Adequate To Achieve Optimal Efficacy With Fixed-Dose Artemether-Lumefantrine: A Review Of The Evidence, Zul Premji, S. Abdulla, B. Ogutu, A. Ndong, C.O. Falade, I. Sagara, N. Mulure, O. Nwaiwu, G. Kokwaro

Pathology, East Africa

A fixed-dose combination of artemether-lumefantrine (AL, Coartem®) has shown high efficacy, good tolerability and cost-effectiveness in adults and children with uncomplicated malaria caused by Plasmodium falciparum. Lumefantrine bioavailability is enhanced by food, particularly fat. As the fat content of sub-Saharan African meals is approximately a third that of Western countries, it raises the question of whether fat consumption by African patients is sufficient for good efficacy. Data from healthy volunteers have indicated that drinking 36 mL soya milk (containing only 1.2 g of fat) results in 90% of the lumefantrine absorption obtained with 500 mL milk (16 g fat). African …

Influence Of Consecutive-Day Blood Sampling On Polymerase Chain Reaction-Adjusted Parasitological Cure Rates In An Antimalarial-Drug Trial Conducted In Tanzania, Andreas Martensson, Johan Ursing, M. Isabel Veiga, Lisa Wiklund, Christopher Membi, Scott M. Montgomery, Zul Premji, Anna Farnert, Andres Bjorkman, Billy Ngasala

Pathology, East Africa

We assessed the influence that consecutive-day blood sampling, compared with single-day blood sampling, had on polymerase chain reaction (PCR)-adjusted parasitological cure after stepwise genotyping of merozoite surface proteins 2 (msp2) and 1 (msp1) in 106 children in Tanzania who had uncomplicated falciparum malaria treated with either sulfadoxine-pyrimethamine or artemether- lumefantrine; 78 of these children developed recurrent parasitemia during the 42-day follow-up period. Initial msp2 genotyping identified 27 and 33 recrudescences by use of single- and consecutive-day sampling, respectively; in subsequent msp1 genotyping, 17 and 21 of these episodes, respectively, were still classified as recrudescences; these results indicate a similar sensitivity …
