Sex difference in clinical presentation of patients with infectious mononucleosis caused by Epstein-Barr virus

An Exploratory Study of the Associations Between Epstein-Barr Virus Antibodies and Forgiveness Among Recipients of Relational Transgressions in the USA

Forgiveness is an important component of many of the world's religions that also has benefits for individuals' health and relationships. Research on the health benefits of forgiveness is couched predominately in the stress and coping framework, which views forgiveness as buffering the stress associated with unforgiving feelings. This exploratory study (N = 47) elaborated on the stress and coping framework by investigating it in conversation with an evolutionary approach. Specifically, this study examined one's own forgiveness index (i.e., the interaction of exploitation risk and relationship value) as moderating an association between forgiveness and Epstein-Barr virus (EBV) antibodies. The results indicated that forgiveness shared no significant association with EBV antibodies at low (16th percentile) levels of relationship value (b = - 11, p = .643), but shared an increasingly significant negative association at moderate (50th percentile: b = - 49, p = .038) and high (84th percentile: b = - 84, p = .009) levels, suggesting that forgiveness was more strongly linked to enhanced immune function when occurring in higher valued relationships. Implications for religion, theory, and methodological comparison are discussed.

Infectious mononucleosis is associated with an increased incidence of Crohn's disease: results from a cohort study of 31 862 outpatients in Germany

OBJECTIVE

The pathogenesis of inflammatory bowel disease (IBD) has not been fully uncovered to date. Epstein-Barr-Virus (EBV) infection has recently been associated with the pathogenesis of multiple sclerosis, suggesting a general link between EBV and autoimmune diseases. However, data on an association between EBV and IBD have remained inconclusive. This study aims at evaluating an association between EBV and the development of IBD.

METHODS

This retrospective cohort study included 15 931 patients with and 15 931 matched patients without infectious mononucleosis from the Disease Analyzer database (IQVIA) between 2000 and 2018. Incidences of Crohn's disease and ulcerative colitis were evaluated using Cox regression models.

RESULTS

Within 5 years of the index date, the cumulative incidence of IBD was 124 and 90 cases per 100 000 person-years among patients with and without infectious mononucleosis, respectively (P = 0.040). In regression analyses, infectious mononucleosis was significantly associated with IBD [hazard ratios (HR), 1.35; 95% confidence interval (CI), 1.01-1.81]. Subgroup analyses revealed an association between infectious mononucleosis and Crohn's disease (HR, 1.93; 95% CI, 1.22-3.05) but not ulcerative colitis (HR, 1.03; 95% CI, 0.70-1.51). This association was strongest in patients between 14 and 20 years (HR, 4.50; 95% CI, 1.55-13.13) and was only observed in females (HR, 2.51; 95% CI, 1.39-4.53).

CONCLUSION

Infectious mononucleosis is significantly associated with an increased incidence of Crohn's disease but not ulcerative colitis, especially in young female patients. Our data support the hypothesis of a pathophysiological involvement of EBV in the development of Crohn's disease and should trigger molecular research to further dissect the pathophysiology of IBD.

Acute dacryoadenitis due to primary Epstein-Barr virus infection

We herein present the case of a 28-year-old male patient who presented with fever and bilateral upper eyelid edema without other upper airway symptoms and was diagnosed with acute dacryoadenitis due to Epstein-Barr virus (EBV) infection. The patient’s medical history was unremarkable. Laboratory tests revealed lymphocytosis with atypical lymphocytes and abnormal liver function tests. Physical examination and computed tomography revealed swelling in the lacrimal glands, and serological tests confirmed EBV infection. Although rare, ocular symptoms of primary EBV infection are important for diagnosis. Acute dacryoadenitis should be considered as a rare manifestation and an underdiagnosed complication of primary EBV infection.

Host Sex Steroids Interact With Virus Infection: New Insights Into Sex Disparity in Infectious Diseases

Sex hormones are steroid hormones synthesized from the gonads of animals and tissues such as the placenta and adrenocortical reticular zone. The physiological functions of sex hormones are complex. Sex hormones are not only pathologically correlated with many diseases of the reproductive system, but are etiological factors in some viral infectious diseases, including disease caused by infections of coronaviruses, herpesviruses, hepatitis viruses, and other kinds of human viruses, which either exhibit a male propensity in clinical practice, or crosstalk with androgen receptor (AR)-related pathways in viral pathogenesis. Due to the global pandemic of coronavirus disease 2019 (COVID-19), the role of androgen/AR in viral infectious disease is highlighted again, majorly representing by the recent advances of AR-responsive gene of transmembrane protease/serine subfamily member 2 (TMPRSS2), which proteolytically activates the receptor-mediated virus entry by many coronaviruses and influenza virus, along with the role of androgen-mediated signaling for the transcription of hepatitis B virus (HBV), and the role of sex hormone responsive genes during Zika virus (ZIKV) pathogenesis, et al. Collectively, we propose to provide a comprehensive overview of the role of male sex hormones during multiple phases in the life cycle of different human viruses, which may be partly responsible for the sex-specific prevalence, severity and mortality of some diseases, therefore, may provide clues to develop more efficient prevention and treatment strategies for high-risk populations.

Investigation on the Correlation between Serum Immune Factor Levels and Allergic Constitution in Children with Infectious Mononucleosis

Objective

To investigate the correlation between serum immune factor levels and allergic constitution in children with infectious mononucleosis.

Methods

A total of 120 children who visited our hospital from March, 2019, to December, 2020, were selected as the research objects, and 40 children who came to our hospital for physical examination were included in the control group (CG). 40 children with IM were classified into the IM group (IG), and 40 IM children with allergic rhinitis, allergic dermatitis, asthma, and other allergic diseases were classified into the IM allergy group (AG). On the second day of admission, 5 ml of fasting venous blood was collected from all children in the early morning to observe the serum IgE level, the level of lymphocyte subsets, and the level of immunoglobulin of the patient.

Results

The serum CD3, CD4, and CD8 levels of children in AG were significantly higher than those in IG and CG (P < 0.05). The serum IgE, IgA, IgM, and IgG levels of children in AG were significantly higher than those of IG and CG (P < 0.05). The serum IgE levels of children in AG were positively correlated with the serum CD3, CD4, and CD8 levels (P < 0.05). There was a positive correlation between the serum IgE level and serum IgA, IgM, and IgG levels in children with AG (P < 0.05).

Conclusion

The results of this study showed that there may be a certain relationship between allergic constitution and the incidence, clinical manifestations, and prognosis of infectious mononucleosis. IgE level can be used as a reference index for the early severity of IM clinical symptoms.
