    AIM: The present systematic review and meta-analysis assessed the strength of a reported association between elevated serum anti-periodontal bacterial antibody responses and coronary heart disease (CHD).

    MATERIALS AND METHODS: Twenty original studies were identified after systematically searching five databases. The majority (n = 11) compared serum anti-Porphyromonas gingivalis (Pg) and/or anti-Aggregatibacter actinomycetemcomitans (Aa) IgG antibody responses between CHD patients and control participants. The strength of the association between serum anti-Pg antibodies and CHD (n = 10) and serum anti-Aa antibodies and CHD (n = 6) was investigated using a meta-analysis approach separately.

    RESULTS: Most studies (61%) reported that the serum IgG antibody responses were elevated in CHD patients than in controls. The meta-analyses showed a significant association between elevated serum IgG antibody responses (anti-Pg and anti-Aa) and CHD, with pooled odds ratios of 1.23 [95% confidence interval (CI): 1.09-1.38, p = .001] and 1.25 (95% CI: 1.04-1.47, p = .0004), respectively.

    CONCLUSIONS: A modest increase of CHD events in individuals with higher serum anti-Pg and anti-Aa IgG antibody responses may support their use as potential biomarkers to detect and monitor at-risk populations. However, the observed inconsistencies with the design and interpretation of immunoassays warrant standardization of the immunoassays assessing antibody responses against periodontal bacteria.

  2. Detection of Serum Antibody Responses in Nipah Virus-Infected Pigs

    Methods Mol Biol, 2023;2610:17-29.

    Nipah virus (NiV) is an emerging, zoonotic paramyxovirus that is among the most pathogenic of viruses in humans. During the first reported outbreak of NiV in Malaysia and Singapore in the late 1990s, pigs served as an intermediate host, which enabled the transmission to humans. Although subsequent outbreaks in Asia only reported direct bat-to-human and human-to-human transmission, pigs are still considered a potential source for viral dissemination in the epidemiology of the disease. Thus, serological assays such as Enzyme-linked immunosorbent assay (ELISA) or virus neutralization test (VNT) represent powerful tools to characterize the serum antibody responses in NiV-infected pigs as well as to perform seroepidemiological surveillance studies on the potential circulation of NiV or NiV-related viruses among pig populations worldwide. This chapter describes both methods in detail. Furthermore, we discuss some of the major pitfalls and indicate how to avoid them.

  3. A survey of antibodies to Adenovirus 8 and Coxsackievirus A21 in human sera

    PMID: 5296130
    Studies have recently been published of surveys of antibodies to common respiratory viruses in human sera from several parts of the world. The present article reports the findings of a survey of antibodies to two more viruses (adenovirus type 8 and coxsackievirus type A21) in human sera mainly collected from six widely separated geographical regions (Alaska, England, Marshall Islands, Sarawak, South-West Africa and Tunisia).A world-wide geographical distribution of infection with these two viruses was found. However, antibodies to individual viruses were not found with the same frequency in all countries; and, in marked contrast to the findings in the earlier surveys of antibodies to the common respiratory viruses, the frequency of antibodies was not the same for each virus in sera from the same country. It was not possible to draw any final conclusions as to the reasons for the observed differences.
