About this study

Official title: New Tools for Diagnosis and Management of Febrile Illness in Travelers to the Tropics: a Cohort Study- JOKA I

This study is part of a larger prospective cohort study (JOKA), designed to study the incidence and etiological spectrum of febrile illness occurring during a travel to the tropics, as well as clinical course, care, treatment and outcome of these febrile illness episodes. Its objective is to evaluate the clinical use of malaria rapid diagnostic tests (RDT) by travelers or their peers during travel, as a decision aid for the management of febrile illness in the tropics.

If the study demonstrates that malaria can be ruled out safely by travelers themselves using a RDT, a combination of self/peer testing with SBET may become an alternative to antimalarial chemoprophylaxis in travel medicine.

Objectives:

To evaluate the clinical use of malaria rapid diagnostic tests (RDT) by travelers or their peers during travel, as a decision aid for the management of febrile illness.

Design: Prospective cohort study of febrile illness in international travelers

Population: Travelers who are going to destinations in the tropics (South-East Asia (SEA), Sub-Saharan Africa (SSA) and South America (SCA)) for 3 weeks or longer will be invited to participate and, after obtaining informed consent, recruited in the study protocol(s) at the time of planning departure (directly at the ITM or through travel/ humanitarian relief organizations).

Methods: Participants will be offered pre-, per- and post-travel consultation as explained below:

Inclusion through ITM; 1. Pre-travel consultation at a certified travel clinic ("Erkend Centrum voor Medisch Reisadvies en Inentingen") will systematically be recommended; this consultation will include:

(1) routine travel advice directed at travel destination, (including vaccinations and prescription for anti-malarial chemoprophylaxis according to current recommendations, details of which are published at www.reisgeneeskunde.be and (2) the following research-related activities:

  • Briefing sessions on the topic "Fever in The Tropics" by an ITM physician (during this session the differences between fever at home and in the tropics will be addressed and the importance of consulting a local doctor will be stressed).
  • Collection and recording of demographic, clinical and travel data.
  • Sampling of a baseline serum sample (for paired pre- and post-travel diagnostic analysis).
  • Training of travelers, peers and travel guides to perform and interpret a malaria RDT (training is a prerequisite for study participation).
  • Provision of study materials (study diary/apps, malaria kits, thermometer, …) and written instructions for use during travel if fever occurs.
  1. During travel
  • In case of any illness (associated with fever or not), the traveler will record symptoms in the study diary.
  • If fever is documented (axillary temperature ≥ 37.8°C - or in case a thermometer is not immediately available, fever sensation in association with sweats or chills)- blood from a finger prick will be collected for use of the malaria rapid diagnostic test (RDT, presenting as a nitrocellulose strip in a plastic cassette).
  • In case of a positive RDT result the traveler is advised to start artemisinin based combination therapy (ACT) as 'standby emergency treatment' (SBET) for malaria as soon as possible.
  • All febrile travelers are advised to seek medical attendance as they would do when not participating in the study.
  • To guide interpretation of the RDT test results, precise instructions will be provided (Annex); to allow post-hoc verification, photographs of the RDT test will be taken at the time of reading, to be kept or sent to the ITM study team for advice (see below)quality control and study documentation. Participants will also asked to store the RDT cassette for further analysis upon return.
  • The final decision to use standby emergency treatment malaria treatment (SBET) is made by the study participant, in accordance with precise and written instructions.
  • The study team (Tropical medicine experts at ITM) will be available for teleconsultation by Email or Telephone, and will provide medical advice (including assistance in RDT reading and interpretation) within 12 hours. Note: contacting the ITM study team is an option, but should not cause delay in treating suspected malaria.
  • Study participants will collect all relevant data related to the (outcome of the) illness episode (duration of symptoms, consultation of a health practitioner, admission/duration of stay in a hospital, treatment received and timing, repatriation)
  1. Post-travel consultation will be scheduled for all study participants who experience(d) any illness (febrile or not) within a week after travel- sooner if the medical condition requires so- and for those who have no complaints but do seek post-travel health evaluation.
  • A structured clinical evaluation will be performed by an expert in travel medicine and will be recorded in the database. Laboratory evaluation will include hematological, biochemical and microbiological/parasitological analysis
  • Used RDTs will be collected for confirmation of the test result by Polymerase Chain Reaction (PCR).
  • Data analysis : All data (demographic, geographic, clinical, laboratory and final diagnosis) will be recorded in an encoded database. Descriptive and inferential statistics as appropriate, STATA 14.
  • Sample size: n= 350 fever cases; at an incidence of fever of 8% a cohort of 4400 (healthy) travelers will be recruited over 30 months (Feb 2016 - Aug 2018).
  • Endpoints:
  • To determine the post-test probability for malaria after a negative RDT result (i.e. excluding power of the RDT) as well as other measures of diagnostic accuracy (sensitivity, specificity, positive predictive value) in travelers with febrile illness, when performed by travelers (or their peers)- compared with PCR detection of Plasmodium spp. on the RDT after return
  • Qualitative description of ease of self-/peer- use of malaria RDT
  • Incidence rates for malaria (by use of RDT and post-travel PCR on RDT)
  • Clinical course and outcomes of (self-)management of febrile illness during travel.

Expected results and relevance:

If the study demonstrates that malaria can be ruled out safely by travelers themselves using a RDT, a combination of self/peer testing with SBET may become an alternative to antimalarial chemoprophylaxis in travel medicine.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. negative predictive value of a malaria RDT when used by travelers with febrile illness

    malaria RDT results will be compared to post hoc PCR diagnosis of malaria on the original test strip; the negative predictive value (NPV) will be calculated in a travelers' cohort. A NPV > 99,0 % will be considered as safe to rule out malaria.

    Measured: up to 12 weeks followup

Secondary outcomes (6)
  1. Qualitative description of ease of self-/peer- use of malaria RDT, measured by a self-reported questionnaire

    Measured: up to 12 weeks

  2. Time to treatment measured from time of obtaining test results by self-reporting

    Use of study diary

    Measured: up to 12 weeks

  3. Duration of symptoms by self-reporting

    Use of study diary

    Measured: up to 12 weeks

  4. Description of clinical symptoms and their frequencies by self-reporting

    Use of study diary
