Starworms study

The Starworms project aims to strengthen the monitoring and surveillance of drug efficacy and anthelmintic resistance in soil-transmitted helminth (STH) programs. As such, it will support deworming programs in their quest to eliminate STHs as a public health problem by 2020. The specific objectives are (1) to validate diagnostic tools to monitor drug efficacy and the spread of anthelmintic resistance, (2) to create a surveillance system that monitors the global patterns of drug efficacy and spread of anthelmintic resistance in STH programs, and (3) to develop supporting tools to plan, analyze and follow up on surveys on drug efficacy and the spread of anthelmintic resistance.

Adding Antibody Testing to Mini-TAS

To compare results from Brugia Rapid tests (in 3 districts) and FTS (in 2 districts) with Wb123 rapid tests and Wb123 and Bm14 ELISA testing.

 

Preliminary Findings

  • In March and April 2017, NIMPE had organized teams to go to the field to collect samples. In Duy Tien district, all of 20 primary schools were visited and 320 pupils were tested. In Quang Ninh district, all of 21 primary schools were visited and 323 students participated in the survey. In Le Thuy district, 35 of 38 primary schools were visited and 344 pupils had blood samples taken. 
  • In total, 987 serum samples were collected but one sample was ran out of serum after doing quick tests (Brugia rapid and FTS). Finally, 986 samples were collected for the antibodies test. The serum samples were kept in frieze (-20 0 C) until analysis. Base on the cut–off 0.096 that was calculated by CDC, no positive case was found by this technique.
  • Wb123 testing was applied in all three districts to detect W. bancrofti antibody. All 986 samples were tested, but no positive case was found. This result did not indicate that the Wb123 testing accuracy is equivalent to FTS but did show that no cross action with B. malayi and other parasites was found within the study. 
  • All 986 serum samples that collected from the three districts in the Mini TAS were tested by Bm14 to detect B.malayi antibody. No positive case was recorded and this result was comparable to the result from Brugia rapid test.
  • Following these data, the researchers supposed that the ELISA testing could be comparable to the quick testing with regards to accuracy. However, since no positive case was found and we could not conclude about the sensitivity and the specificity of the test. Therefore, a further study should be continued especially in endemic areas in which possibly can find some positive cases for assessment and conclusion.

Integrated Transmission Assessment Surveys (iTAS) and Onchocerciasis evaluation in areas of Co-Endemicity for both infections in Tanzania

To determine the validity and programmatic feasibility of an integrated transmission assessment survey (F-TAS), to be used to simultaneously assess Onchocerciasis (Oncho) and Lymphatic Filariasis (LF) prevalence in areas co-endemic for the two infections that have completed the recommended treatment for one or both infections.

STH Diagnostic Comparison: PCR vs. Kato-Katz, Uganda

To determine if a standardized multi-parallel-PCR assay is a more sensitive diagnostic tool for detecting Hookworm (Ancylostoma duodenale and Necator americanus), Trichuris trichiura, Ascaris lumbricoides, Strongyloides stercoralis, and Schistosoma mansoni prevalence compared to the Kato-Katz stool test.
