Background: Persistent physical fatigue (PPhF) accompanying daily intensive training often results in underperformance. While salivary secretory immunoglobulin A (SIgA) has been traditionally used as an immunological marker, salivary human herpesvirus 6 and/or 7 (HHV-6/7) have recently been presented as "microbiological" markers of PPhF. This study aimed to examine the monthly variabilities of salivary HHV-6/7 levels and the difference with SIgA along the training periodization.

Article Synopsis
  • Pityriasis rosea (PR) is a skin condition that usually gets better on its own, often linked to reactivated human herpesviruses, causing mild rashes and itchiness.
  • Traditional treatment focuses on reassuring patients to rest, but severe cases may require medication, prompting a study comparing various treatments.
  • The analysis found that oral steroids and a combo with antihistamines were effective for itch relief, while acyclovir was the most effective for improving rash symptoms, making it the best option for more serious PR cases.

Article Synopsis
  • * The study included 17 FM patients and 24 healthy individuals, aiming to identify potential biomarkers, detecting human herpesvirus (HHV)-6A and B in patient samples, and measuring related antibodies and cytokine levels.
  • * Findings indicated higher detection of HHV-6B in FM patients, particularly those with a BMI of 30 or more, along with significant differences in gut microbiome diversity between FM patients and healthy controls.

Article Synopsis
  • Herpesviruses are common complications after allogeneic hematopoietic cell transplantation (HCT), but recent advancements have improved their prevention and treatment over the past decade.
  • Key developments include the introduction of letermovir and maribavir for cytomegalovirus (CMV) infections, the recombinant zoster vaccine for varicella zoster virus, and ongoing research into treatments for herpes simplex virus and Epstein-Barr virus.
  • Despite these advances, challenges remain, particularly with Human Herpesvirus-6, and future strategies may involve new antivirals and enhanced immune therapies to further improve management of these infections.

Human herpesvirus 6 (HHV-6) is a widely spread DNA virus that is ubiquitous and persistent with primary infection occurring in early childhood, with reactivation of the infection a common phenomenon in severely immunocompromised hosts, including hematopoietic stem cell transplant (HSCT) patients, influencing morbidity and mortality. A wide spectrum of clinical presentations is reported in the literature with HHV-6 reactivation including post-transplant limbic encephalitis (PALE). We report the unusual case of a 6-year-old female 107 days postallogenic HSCT due to transfusion dependent beta thalassemia major who developed acute cerebellitis with secondary supratentorial hydrocephalus that required invasive surgical intervention.
