Title

PSOP24-377: An infectious bite marker for sensitive malaria detection and population level surveillance

Objectives

The overarching goal of the study is to validate novel malaria infectious-bite marker as a simple straightforward sero-surveillance tool to identify ‘hotspots’ and ‘hotpops’ for targeted interventions to yield maximum community-wide benefits. Specific Objectives 1. Determine kinetic antibody response to novel infectious-bite markers, gSG6-P1, PSOP24 and CSP and to compare with newly reported up-regulated salivary gland peptides 2. To compare with parasite prevalence with parasite prevalence, and entomological indices at household levels in study populations 3. Identify micro-geographic heterogeneities in malaria transmission using ArcGIS and spatial statistics, this will test the sensitivity and the reliability of sero-surveillance in identifying hotspots for targeted control 4. To find out the role of submicroscopic infections in malaria transmission at the household levels.

Study Design

Study design: This will be three -time point longitudinal community based survey at quarterly intervals cutting across both dry and rainy season. Serological, parasitological and entomological as well as demographic data will be collected at household level. The study will not discriminate participants in terms of age or gender but a representation of all age groups except infants of less than 6months where maternal antibodies drive immune response rather than exposure will be excluded. Blood samples from finger prick will be taken from an average of 4 people per household from 100 households per community. Measurement of humoral responses All test samples will be tested for anti-infectious-bite markers, CSP and anti-gSG6-P1 human IgG antibodies by ELISA using standard methodology [Badu et al 2012a]. Test sera will be serially diluted in duplicate on the plates from 1:50 to 1:64,000. Serial dilutions will be used to fit a four-parameter curve using SoftMax Pro v4.1 (Molecular Devices). Results will be expressed in titer values, the titer endpoint being defined as the calculated serum dilution yielding an optical density of 1.0. Expected Outcome The overarching goal of the study is to validate novel malaria infectious-bite marker as a simple straightforward sero surveillance tool to identify ‘hotspots’ and ‘hotpops’ for targeted interventions to yield maximum community-wide benefits. This proposal will seek to determine heterogeneity in antibody response to infectious-bites markers corresponding to exposure to infected Anopheles mosquitoes to identify restricted geographical areas (household –level) in which there is a higher level of transmission intensity.

Study Design:
APPROACH The proposed research will use rationally designed and synthesized ionic probes (Aim 1) to facilitate ultrasensi-tive mass spectrometric detection of malaria biomarkers captured on paper-based microfluidic analytical plat-form (Aim 2). The 3D paper device supports both immunoassays (i.e., antibody reactions) and on-chip MS de-tection. In Aim 3, we will establish the correlation between biomarker (HRP-2 and Aldolase) concentration and parasite density using blood spiked with parasitized erythrocytes and clinical blood samples via analysis on ex-isting bench-top ion trap mass spectrometer, capable of MS/MS. To evaluate our on-demand diagnostic approach (in terms of stability, specificity and sensitivity), clinical sam-ples will be collected directly on the paper device in both low-risk (peri-urban community) and high-risk (remote field) settings in Ghana. In this surveillance on-demand testing, de-identified samples collected from both peri-urban and rural settings will comprise of sick hospitalized (symptomatic) population and community-based (asymptomatic) population. To address biological variability due to sex, we will use known malaria prevalence for male and female to determine sample size. The three Aims are integrated, but differ in many respects includ-ing the specific experimental design. Thus, this section is divided into rationale, experimental design and prelimi-nary data, expected results, and potential pitfalls.
Subjects:
Malaria surveillance and Diagnostics
Outcomes:
We expect to achieve the following milestones at the end of Aim 1: (1) to reach an optimized probe de-sign/structure that is stable after immunoassay enabling easy storage and transport for centralized test analy-sis; (2) to have established an amplification strategy that (i) has minimal effect on antibody binding capacity and (ii) provides PCR-level sensitivity through MS; and (3) to have developed probe stimulation chemistry that is fast or can be terminated (after initiation) to allow effective control of the MS signal amplification process. With-out signal amplification, our current detection limit (2.8 ng/mL) is comparable to that of ELISA (1 ng/mL) for HRP 2 antigen.24 Therefore, we believe the proposed amplification strategy will afford sensitivities close to that of PRC using only finger prick blood (~20 μL). We expect to develop a self-sustained paper device that requires no special storage conditions. The devices are expected to be reliable for at least 30 days after the time of use. Patients are expected to perform only two tasks when using the device: (1) application of sample and (2) the addition of a wash buffer to remove unbound species.
