Background: Asymptomatic carriers of P. falciparum
constitute a reservoir for infection of newly hatched
mosquitoes.
Objectives: Controlled, parallel, cluster-randomized
(intervention=9, control=9) 12-month study was con-
ducted in Burkina Faso to evaluate impact at community
level of systematic screening and artemether-
lumefantrine (AL)/AL dispersible treatment of RDT-
detected ACs during 3 community screening campaigns
(CSCs1-3).
Methods: CSCs1-3 were successively placed 1 month
apart before rainy season and CSC4 1 year later. Symp-
tomatic malaria episodes were treated with AL or an
alternative in both arms. Proportion of gametocyte carri-
ers (GCs) was evaluated by microscopy in all subjects at
CSCs1-4 in intervention arm and in randomly selected
40% subset of control arm, and by qRT-PCR at CSC4 in
1,999 randomly selected subjects across both arms.
Results: Prevalence of microscopy-confirmed ACs in
intervention and control arms was 42.8%vs47.5%, 4.1%
vs35.7%, 2.8%vs32.2% and 34.4%vs37.8% at CSC1,
2,3 and 4, respectively. Overall proportion of GCs in
intervention and control arms was 9.5%vs10.2%, 0.6%
vs5.5%, 0.4%vs5.8% and 4.8%vs5.1% at CSC1, 2,3 and
4, respectively. Prevalence (least square mean [SE]) of
microscopy-confirmed GCs at CSC4 in intervention arm
was 4.9 (0.41) vs 5.1 (0.41) in control arm (p=0.7208).
Prevalence of GCs at CSC4 as assessed by qRT-PCR
was around 8-fold greater in both arms compared to
microscopy (intervention=49.7%vs6.0%; control=47.3%
vs5.4%).

Background: Artemether-lumefantrine (AL) and dihy-
droartemisinin-piperaquine (DP) have been introduced
as first and second-line treatment, respectively, for un-
complicated falciparum malaria in Kenya.
Objectives: Primary objective was to compare corrected

ACPR) on Day 28 in children treated with AL dispersi-
ble (AL ) and DP pediatric (DP ) with uncomplicated
falciparum malaria.

Methods: This open-label, comparative study in Western
Kenya randomized 454 children with uncomplicated
falciparum malaria of age 6-59 months to receive either
d p
AL (n=227) or DP (n=227). Children were hospitalized
for 3-days for observed treatment and followed up on
Days 7, 14, 28 and 42. Adherence to treatment and ac-
ceptability were assessed by caregiver questionnaire.
Results: No significant differences were observed for
corrected ACPR rates on Day 14,28 and 42 for AL
100%,97.8%,and 96.8%) and DP (100%,99.1%,and
8.7%;p>0.05 for all comparisons). For uncorrected
ACPR rates no significant differences were observed on
Day 3,14, 28 and 42 for AL (99.1%, 98.7%,81.1%, and
group (100%,100%,87.7%,and
0.5%;p>0.05 for all comparisons). Overall incidence of

Conclusions: In this community-setting study, interven-
tion arm showed greater reductions in prevalence of
ACs and GCs than control arm at CSCs2 and 3, relative
to CSC1(p<0.0001). However, AC and GC prevalence
rose thereafter in intervention arm to reach a level simi-
lar to control arm at CSC4.
AEs was 65.5% (156/238) and 67.5% (156/231) in AL
and DP arms. Adherence to treatment regimen was
higher for AL arm (93.6%) compared to DP (85.6%)
arm. 82% considered AL ‘simple’ or ‘very simple’ to
use compared with 67% in DP arm (p=0.007). Taste of
AL was ‘liked’ or ‘liked very much’ by 72% of respon-
dents, compared with 56% for DP
Conclusions: Both AL and DP

Impact of Community Screening and Treatment of
Asymptomatic Carriers of Plasmodium Falciparum
with Artemether-Lumefantrine on Asymptomatic
and Gametocyte Carriage: A 12-Month, Cluster-
Randomized Study In Sub-Saharan Africa
Department of Paediatrics, Ahmadu Bello University

Background: Pneumonia is responsible for 17% of all
under –five deaths in Nigeria. In March 2009, Nigerian
government revised the National Immunization Policy to
include “new and underutilized vaccines” among which
are the Pneumococcal Conjugate and Haemophilus In-
fluenza B vaccines that prevent 2 of the most prevalent
causes of pneumonia in childhood. These antigens be-
came part of routine vaccines in Kaduna State, one of
states in the first phase of implementation of this immu-
nization policy.
