Abstract

Background: Tuberculosis (TB) remains a primary global health concern, with Indonesia accounting for approximately 10% of international cases. Tumor necrosis factor-alpha (TNF-α) plays a crucial role in the immune response against Mycobacterium tuberculosis, particularly in pulmonary tuberculosis (TB).Method: This article is a narrative literature review that examines the role of tumor necrosis factor-alpha (TNF-α) in pulmonary tuberculosis.Result:  This pro-inflammatory cytokine is essential for activating macrophages, promoting phagolysosome fusion, and supporting the formation and maintenance of granulomas—immune structures critical for containing infection. However, dysregulated TNF-α expression can be detrimental: excessive levels contribute to inflammation and lung tissue damage, while insufficient production—such as that induced by TNF-α inhibitor therapy—can lead to reactivation of latent TB. This narrative review examines the biosynthesis, immunological functions, and regulatory mechanisms of TNF-α in the context of pulmonary tuberculosis, highlighting its dual role in protective immunity and immunopathology.Conclusion: A deeper understanding of TNF-α modulation may inform the development of targeted, host-directed therapies that improve treatment outcomes while minimizing tissue damage.

Abstract

Background: Toxoplasma gondii is an obligate intracellular protozoan responsible for toxoplasmosis, a globally prevalent parasitic infection affecting more than one-third of the world’s population. Accurate and timely diagnosis is crucial, particularly for pregnant women and immunocompromised individuals, to prevent severe complications such as congenital toxoplasmosis and encephalitis. The enzyme-linked immunosorbent assay (ELISA) is widely regarded as a reference serological method due to its high sensitivity and specificity. In contrast, rapid diagnostic tests (RDTs) offer practical advantages but show variable diagnostic performance.Method: This systematic review evaluated and compared the diagnostic accuracy of ELISA and RDTs for toxoplasmosis. Literature searches were conducted in PubMed and Google Scholar for studies published between 2015 and 2025. Eligible studies assessed the diagnostic performance of ELISA and RDTs for detecting T. gondii infection in human populations, including sensitivity, specificity, and overall accuracy.Result: Five studies met the inclusion criteria. Across diverse populations, ELISA consistently demonstrated high diagnostic accuracy, with sensitivity and specificity exceeding 90% in most studies. In contrast, RDTs showed lower performance and greater heterogeneity, particularly in individuals with low antibody titers and in immunocompromised individuals. Nevertheless, RDTs provided operational advantages for rapid screening in low-resource settings.Conclusion: ELISA remains the most reliable method for serological diagnosis of toxoplasmosis, while RDTs may serve as complementary tools for initial screening. The integration of both approaches, along with the adoption of advanced ELISA formats such as recombinant antigen-based or Nano-Gold ELISA, may improve early detection and enhance diagnostic capacity across different healthcare settings.
