  • Antiviral treatment associated with reduced risk of clinical Alzheimer's disease : A nested case-control study
  • 2021
  • Ingår i: Alzheimer’s & Dementia. - : John Wiley & Sons. - 2352-8737. ; 7:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: In this nested case-control study, we investigated if antiviral treatment given prior to onset of Alzheimer's disease (AD) could influence incident AD.Methods: From a large population-based cohort study in northern Sweden, 262 individuals that later developed AD were compared to a non-AD matched control group with respect to prescriptions of herpes antiviral treatment. All included subjects were herpes simplex virus 1 (HSV1) carriers and the matching criteria were age, sex, apolipoprotein E genotype (ε4 allele carriership), and study sample start year.Results: Among those who developed AD, 6 prescriptions of antivirals were found, compared to 20 among matched controls. Adjusted for length of follow-up, a conditional logistic regression indicated a difference in the risk for AD development between groups (odds ratio for AD with an antiviral prescription 0.287, P = .018).Discussion: Antiviral treatment might possibly reduce the risk for later development of HSV1-associated AD.

  • Prevalence of pain and pharmacological pain and treatment among old people in nursing homes in 2007 and 2013
  • 2018
  • Ingår i: European Journal of Clinical Pharmacology. - : Springer. - 0031-6970 .- 1432-1041. ; 74:4, s. 483-488
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: Many elderly people living in nursing homes experience pain and take analgesic medication. The aim of this study was to analyze the prevalence of pain and pharmacological pain treatment among people living in nursing homes in Sweden, in two large, comparable, samples from 2007 to 2013.Methods: Cross-sectional surveys were performed in 2007 and 2013, including all residents in nursing homes in the county of Västerbotten, Sweden. A total of 4933 residents (2814 and 2119 respectively) with a mean age of 84.6 and 85.0 years participated. Of these, 71.1 and 72.4% respectively were cognitively impaired. The survey was completed by the staff members who knew the residents best.Results: The prescription of opioids became significantly more common while the use of tramadol decreased significantly. The staff reported that 63.4% in 2007 and 62.3% in 2013 had experienced pain. Of those in pain, 20.2% in 2007 and 16.8% in 2013 received no treatment and 73.4 and 75.0% respectively of those with pain, but no pharmacological treatment, were incorrectly described by the staff as being treated for pain.Conclusions: There has been a change in the pharmacological analgesic treatment between 2007 and 2013 with less prescribing of tramadol and a greater proportion taking opioids. Nevertheless, undertreatment of pain still occurs and in many cases, staff members believed that the residents were prescribed analgesic treatment when this was not the case.

  • Herpesvirus infections, antiviral treatment, and the risk ofdementia : a registry-based cohort study in Sweden
  • 2021
  • Ingår i: Alzheimer’s & Dementia. - : John Wiley & Sons. - 2352-8737. ; 7:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Herpesviruses, including Herpes simplex virus type 1 (HSV1) and varicella zoster‐virus (VZV), have been implicated in Alzheimer's disease (AD) development. Likewise, antiviral treatment has been suggested to protect against dementia development in herpes‐infected individuals.Methods: The study enrolled 265,172 subjects aged ≥ 50 years, with diagnoses of VZV or HSV, or prescribed antiviral drugs between 31 December 2005 and 31 December 2017. Controls were matched in a 1:1 ratio by sex and birth year.Results: Antiviral treatment was associated with decreased risk of dementia (adjusted hazard ratio [HR] 0.89, 95% confidence interval [CI] 0.86 to 0.92), while herpes infection without antiviral drugs increased the risk of dementia (adjusted HR 1.50, 95% CI 1.29 to 1.74).Discussion: Antiviral treatment was associated with a reduced long‐term risk of dementia among individuals with overt signs of herpes infection. This is consistent with earlier findings indicating that herpesviruses are involved in the pathogenesis of AD.

  • VALZ-Pilot : High-dose valacyclovir treatment in patients with early-stage Alzheimer's disease
  • 2022
  • Ingår i: Alzheimer’s & Dementia. - : John Wiley & Sons. - 2352-8737. ; 8:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Herpes simplex virus (HSV) may be involved in Alzheimer's disease (AD) pathophysiology. The antiviral valacyclovir inhibits HSV replication.Methods: This phase-II pilot trial involved valacyclovir administration (thrice daily, 500 mg week 1, 1000 mg weeks 2–4) to persons aged ≥ 65 years with early-stage AD, anti-HSV immunoglobulin G, and apolipoprotein E ε4. Intervention safety, tolerability, feasibility, and effects on Mini-Mental State Examination (MMSE) scores and cerebrospinal fluid (CSF) biomarkers were evaluated.Results: Thirty-two of 33 subjects completed the trial on full dosage. Eighteen percent experienced likely intervention-related mild, temporary adverse events. CSF acyclovir concentrations were mean 5.29 ± 2.31 μmol/L. CSF total tau and neurofilament light concentrations were unchanged; MMSE score and CSF soluble triggering receptor expressed on myeloid cells 2 concentrations increased (P = .02 and .03).Discussion: Four weeks of high-dose valacyclovir treatment was safe, tolerable, and feasible in early-stage AD. Our findings may guide future trial design.
