Background: Several studies have proposed viral infection with herpes simplex virus (HSV) as a probable cause of vitiligo. We aimed to examine the association between HSV infection and vitiligo.
Methods: We used the National Health Insurance Research Database of Taiwan to perform a comparative analysis of the study population with or without a diagnosis of HSV infection. The study period was from January 1st, 2008, to December 31st, 2019. The primary outcome was the date of first vitiligo diagnosis, death, withdrawal from the National Health Insurance Program, or end of the study.
Results: We performed 1:1 propensity score matching based on age, sex, and comorbidities, resulting in 1,009,445 matched pairs of patients with and without HSV infections. The adjusted hazard ratio for developing vitiligo in the HSV cohort was 1.71 (95% confidence interval, 1.59 - 1.83; P < 0.001). An age-dependent pattern was also observed among HSV-infected patients with vitiligo (P for interaction < 0.001). Both sexes exhibited a significantly higher risk of developing vitiligo in the presence of HSV infection. The HSV cohort significantly increased cumulative vitiligo risk compared to the non-HSV cohort in a 12-year follow-up (log-rank P < 0.001). The result of sensitivity analysis was compatible with that of primary analysis. Patients with HSV infection had a considerably increased vitiligo risk within the 1-year follow-up than the non-HSV cohort (adjusted hazard ratio, 4.83; 95% confidence interval, 4.04 - 5.77, P < 0.001).
Conclusion: This nationwide population-based study demonstrated an association between HSV infection and an increased risk of vitiligo. Further investigation of HSV DNA in the affected regions of vitiligo lesions may help to establish causality.

Introduction: Reactivation of herpes simplex virus (HSV) and varicella zoster virus (VZV) is a potential complication following allogeneic stem cell transplantation (alloSCT). Since different doses and durations of acyclovir prophylaxis may be utilized across transplant centers, this study aimed to evaluate the effectiveness of a lower dose of acyclovir in preventing HSV and VZV reactivation in alloSCT recipients within our institution.
Methods: A retrospective chart review was conducted for patients who underwent alloSCT between April 2016 and May 2023.

Brown seaweeds are known for their bioactive compounds, particularly sulfated polysaccharides such as fucoidans, which have demonstrated antiviral properties. However, limited studies have focused on the antiviral potential of fucoidans extracted from Mediterranean brown seaweeds. In this study, two brown seaweeds Padina pavonica and Dictyopteris membranacea (Fuc-Pad and Fuc-Dic) were collected from monastir coasts, Tunisia, and a specific extraction protocol was employed to obtain fucoidans.

We present the case of a 51-year-old man with Von Hippel-Lindau disease and a history of renal transplantation who developed a persistent, painful tongue lesion with episodes of significant swelling. Given his history of prolonged immunosuppression and elevated cancer risk, oral squamous cell carcinoma was a major concern. However, histopathological evaluation confirmed recrudescent herpes simplex virus (HSV) infection rather than malignancy.

Background: Approximately 2% of HerpeSelect herpes simples virus type 2 (HSV-2) IgG enzyme immunoassay (screen assay) sera-positive samples do not confirm using an HSV-2 IgG inhibition assay. Of these, roughly 1.33% are confirmed negative, and a small proportion (0.

In herpesvirus, the terminase subunit pUL15 is involved in cleavage of the viral genome concatemers in the nucleus. Previous studies have shown that herpes simplex virus 1 (HSV-1) pUL15 can enter the nucleus without other viral proteins and help other terminase subunits enter the nucleus. However, this study revealed that duck plague virus (DPV) pUL15 cannot localize independently to the nucleus and can only be localized in the nucleus in the presence of pUL28 and pUL33.
