Insights
Coronavirus disease 2019 (COVID-19) did not increase lethal outcomes in individuals with human T-cell leukemia virus type 1 (HTLV-1). However, HTLV-1 patients with COVID-19 frequently experienced post-COVID symptoms, highlighting the need for mental health support.
Area of Science:
- Infectious Diseases
- Virology
- Immunology
Background:
- The impact of COVID-19 on individuals with human T-cell leukemia virus type 1 (HTLV-1) remains unclear.
- HTLV-1 infection is a chronic viral infection with potential immune system implications.
Purpose of the Study:
- To evaluate COVID-19 risk factors and outcomes in HTLV-1-infected individuals.
- To investigate the clinical features and vaccination status of HTLV-1 patients during the COVID-19 pandemic.
Main Methods:
- Retrospective study of 51 HTLV-1 seropositive outpatients in Rio de Janeiro, Brazil (2020-2022).
- Comparison of demographic and comorbidity factors between COVID-19 and non-COVID-19 groups.
- Analysis of clinical features, severity, and post-COVID-19 symptoms in infected individuals.
Main Results:
- 19 out of 51 (37.3%) HTLV-1 individuals were diagnosed with COVID-19.
- Anxiety was significantly more frequent in the COVID-19 group (57.9%) compared to the non-COVID-19 group (15.6%).
- Most COVID-19 cases (68%) had mild/moderate illness; 26.3% had severe illness. Post-COVID symptoms were common (57.9%), particularly in unvaccinated individuals.
Conclusions:
- HTLV-1 infection did not appear to increase the risk of severe or lethal COVID-19 outcomes.
- HTLV-1 patients are susceptible to post-COVID-19 conditions, emphasizing the need for mental health monitoring.
- Vaccination status and mental health support are crucial for HTLV-1-infected individuals during the COVID-19 pandemic.
Abstract:
The impact of coronavirus disease 2019 (COVID-19) on people living with human T-cell leukemia virus type 1 (HTLV-1) is unknown. The aim of this study is to evaluate the COVID-19 risk factors and outcomes of HTLV-1-infected individuals. A retrospective study of seropositive HTLV-1 outpatients seen during the COVID-19 pandemic period (2020-2022) was conducted in a Tertiary Hospital in Rio de Janeiro, Brazil. We compared the demographic and comorbidity/risk factors in patients with COVID-19 and non-COVID-19 diagnoses. In addition, the clinical features of COVID-19 and vaccination status were also investigated in 51 HTLV-1-infected individuals. The majority (88.2%) had COVID-19 comorbidity/risk factors. Seven cases were vaccinated against COVID-19. Overall, 19 out of 51 (37.3%) individuals were diagnosed with COVID-19. We found differences only in the frequency of anxiety in both groups: 57.9% in the COVID-19 group vs. 15.6% in the non-COVID-19 (p < 0.05) group. Thirteen out of nineteen (68%) of the COVID-19 cases progressed to mild/moderate illness, one remained asymptomatic, and 26.3% progressed to severe illness. All of the individuals recovered at home, but the majority (57.9%) developed post-COVID-19 symptoms: anosmia and ageusia (31.6%), worsening anxiety (15.8%), and a feeling of pain in the legs (15.8%). The patients with post-COVID-19 conditions were unvaccinated. Our findings show that HTLV-1 did not increase the risk of lethal COVID-19 and underline the importance of promoting mental health in HTLV-1-infected individuals.
