Abstract

Diagnosis of tuberculous meningitis (TBM) is often difficult. A reliable, simple, and rapid diagnostic test that can be performed in any standard laboratory could be helpful in TBM diagnosis. In this study, a loop-mediated isothermal amplification assay (LAMP) was evaluated to rapidly detect and diagnose TBM infection and was compared to the performance of nested PCR. Six specific primers were used to recognize the IS6110 genomic sequence from Mycobacterium tuberculosis, which included one forward outer primer, one reverse outer primer, two respective inner primers, and two loop primers. The optimum reaction temperature and time were 63°C and 60 min, respectively. Nested PCR was performed targeting the IS6110 region from M. tuberculosis using a commercial kit. The LAMP method yielded a sensitivity of 88.23% and a specificity of 80%, compared to the nested-PCR assay, which yielded a sensitivity of 52.9% and a specificity of 90% for TBM diagnosis. Comparative experiments showed that the LAMP assay is a rapid, sensitive, and specific method to detect TBM infection and that it is superior to the nested-PCR assay. LAMP is very simple, and it can be performed in any laboratory and in rural settings.

  • LAMP and NASBA have been studied in various CNS infections and might especially be useful in laboratories with limited resources.

    “LAMP and NASBA have been studied in various CNS infections and might especially be useful in laboratories with limited resources (26–31).”

    From Molecular diagnostics in cerebrospinal fluid for the diagnosis of central nervous system infections (2024) · cites this paper as [27]

    The Introduction (page unavailable) says LAMP could be adopted by any laboratory, and the Discussion (page unavailable) describes its use for diagnosing tuberculous meningitis with an inexpensive turbidometer. This supports the LAMP example and suggests potential use in resource-limited laboratories, but the paper does not study NASBA or LAMP across various CNS infections. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
