Special Issue Information

Dear Colleagues,

Neglected tropical diseases (NTDs) remain a major public health problem in tropical and subtropical regions, with 10% of the world’s population being infected. The management and control of NTDs have been hampered by the difficulty in deploying rapid, specific, and affordable diagnostic tools in low-resource settings. Point-of-care real-time PCR (POC-qPCR) and loop-mediated isothermal amplification (LAMP) have emerged as an alternative to PCR for molecular diagnostics of NTDs, allowing a more affordable approach. These assays have been developed for the diagnosis of various NTDs and diseases associated with sanitary emergencies. These assays have shown promising results when compared to traditional methods. However, to address the diagnostic needs for NTDs, context-specific solutions are required that consider the end-user needs, available resources, and treatment options. Integrating diagnostic solutions to address multiple diseases simultaneously can help reduce the global burden of NTDs. In summary, molecular diagnostic techniques show promise for improving the diagnosis of NTDs, further research and development are needed to overcome the current limitations and ensure their widespread implementation as cost-effective, sensitive, and specific POC tests in endemic regions. So, we encourage this publication type demonstrating novel assays using molecular methods in microbiology and parasitology in novel emergency conditions and NTD diseases.

Background/Objectives: Leptospirosis is a zoonotic disease that is widely distributed around the world and presents symptoms similar to other febrile illnesses in tropical regions, which complicates clinical diagnosis. This study aimed to evaluate the performance and agreement between serological diagnostic tests for detecting both acute and convalescent human leptospirosis, using the micro agglutination test (MAT) as a reference in an endemic region of the Colombian Caribbean. Methods: A prospective descriptive study was conducted on 275 participants with suspected leptospirosis. Paired serum samples were obtained, and an epidemiological survey was conducted. Using the MAT as the gold standard, we calculated positive and negative predictive values, sensitivity, specificity, and kappa index. A Bayesian latent class model was also used to compare the diagnostic tests. Results: In 223 paired serum samples, the sensitivity values for various stages of the disease ranged between 10.8% to 54.1% in the acute and 6.1% to 66.7% during the convalescent phase compared to the MAT. According to the Bayesian model, sensitivity was 9.5% to 75.3% in the acute phase and 5.7% to 85.3% in the convalescent phase. The Kappa value, an indicator of agreement, was moderate for the IgM ELISA in the acute phase (0.553) and substantial in the convalescent phase (0.692). Conclusions: The MAT was the best confirmatory test in both acute and convalescent phases of leptospirosis. Despite the high specificity of ELISA, 21.62% of participants identified as negative by IgM-ELISA in both phases were subsequently confirmed as positive by the MAT. It is necessary to re-evaluate diagnostic guidelines that do not employ the MAT for confirmation and to enhance the diagnostic and clinical identification of leptospirosis within healthcare institutions and public health laboratories while providing a rapid and reliable test for its implementation.
