Increased risk of chronic fatigue syndrome following infection: a 17-year population-based cohort study

Area of Science:

• Infectious Diseases
• Epidemiology
• Immunology

Background:

• Previous research suggests links between viruses, atypical pathogens, and Chronic Fatigue Syndrome (CFS).
• This study investigates the association between common infections and the risk of developing CFS.

Purpose of the Study:

• To determine the correlation between common pathogen infections and the subsequent risk of Chronic Fatigue Syndrome (CFS).
• To analyze data from Taiwan's National Health Insurance Research Database for insights into infection-CFS relationships.

Main Methods:

• A population-based retrospective cohort study involving 395,811 individuals aged 20+ diagnosed with infection between 2000-2017.
• Propensity score matching (1:1) was used to pair infected cases with controls, followed until CFS diagnosis.
• Cox proportional hazards regression analysis was employed to assess the infection-CFS risk relationship.

Main Results:

• The incidence rate of CFS was higher in the infected population (5.40 per 1000 person-years) compared to the non-infected group (3.67 per 1000 person-years).
• Infections with Varicella-zoster virus, Mycobacterium tuberculosis, E. coli, Candida, Salmonella, S. aureus, and influenza virus were associated with a significantly higher risk of CFS.
• Certain antibiotics (doxycycline, azithromycin, moxifloxacin, levofloxacin, ciprofloxacin) were linked to a significantly lower risk of CFS.

Conclusions:

• Common infections, including bacterial and viral pathogens, are associated with an increased risk of developing Chronic Fatigue Syndrome (CFS).
• The findings underscore the potential role of infections in the etiology of CFS.
