New Study Reveals Leukocyte count as Key Predictor of Long COVID Severity in Postmenopausal Women
CLEVELAND, Ohio (Jan 29, 2025)—While advancements in treatment have made a COVID-19 diagnosis less daunting for many, a groundbreaking study published today in Menopause, the journal of The Menopause Society, suggests that predicting who is most likely to suffer severe long-term symptoms may now be easier. The study highlights leukocyte count, a widely available and inexpensive clinical marker of inflammation, as a meaningful predictor of COVID-19 symptom severity, particularly in postmenopausal women.
Millions worldwide continue to grapple with the lingering effects of COVID-19, caused by the SARS-CoV-2 virus, months after their initial diagnosis. Cognitive impairment and fatigue are the most common symptoms, with cognitive impairment affecting 70% of patients. Older adults,especially women,are at the highest risk.
Although healthcare professionals have gained substantial knowlege about COVID-19 since the pandemic began in 2020, questions remain about its long-term impact on the body. While primarily a respiratory disease, COVID-19 has been shown to affect multiple organ systems, with previous studies pointing to an excessive immune response as a contributing factor.
This latest study,based on a secondary analysis of data from the Women’s Health Initiative,aimed to identify preexisting risk factors that make certain individuals—particularly older postmenopausal women—more susceptible to severe long-term symptoms.Researchers focused on whether leukocyte count,a marker of systemic inflammation,could be linked to COVID-19 outcomes.
The findings were striking. Leukocyte count emerged as an independent predictor of COVID-19 symptom severity in postmenopausal women. The study also reinforced the idea that low-grade inflammation not only results from severe COVID-19 symptoms but may also precede acute infection.
“As the authors highlight, post-acute sequelae of severe acute respiratory coronavirus 2 infection considerably affects quality of life, often leading to severe disability. This effect is particularly pronounced in women, who already experience higher rates of cognitive impairment after menopause. By understanding underlying factors, we can better address these challenges and work to mitigate the cascade of symptoms that follow,” says Dr. Monica Christmas, associate medical director for The Menopause Society.
The implications of this research are significant. Leukocyte count is an easily accessible and cost-effective clinical marker, making it a practical tool for healthcare providers to assess risk and tailor treatment plans for postmenopausal women.

A groundbreaking study published on January 29, 2025, reveals a significant connection between pre-pandemic leukocyte counts and the severity of post-acute sequelae of SARS-CoV-2 infection (PASC), commonly known as long COVID, among older women. The research, conducted as part of the Women’s Health Initiative, utilized data/statistical analysis to uncover this critical link, offering new insights into the biological factors that may predispose individuals to severe long-term COVID-19 symptoms.
The study focused on older women, a demographic particularly vulnerable to the lingering effects of COVID-19.Researchers found that those with higher leukocyte counts before the pandemic were more likely to experience severe long COVID symptoms. Leukocytes, or white blood cells, play a crucial role in the body’s immune response, and their levels can indicate underlying inflammation or immune system activity.
“This research highlights the importance of pre-existing immune system markers in predicting the severity of long COVID,” the authors noted. The findings suggest that monitoring leukocyte counts could help identify individuals at higher risk for prolonged and severe post-COVID complications.

| Study Focus | Pre-pandemic leukocyte counts and long COVID severity in older women |
| Methodology | Data/statistical analysis |
| Key Discovery | Higher leukocyte counts linked to more severe long COVID symptoms |
| Implications | Potential for early risk identification and targeted interventions |
The study’s findings are particularly relevant given the ongoing challenges of long COVID, which affects millions worldwide. Symptoms can range from fatigue and brain fog to more severe cardiovascular and respiratory issues, significantly impacting quality of life.
This research underscores the need for further investigation into the role of immune system markers in long COVID.By understanding these biological predictors, healthcare providers can develop more personalized approaches to prevention and treatment.

Editor: Can you provide an overview of the study’s primary objectives and key findings?
guest: Certainly. The primary objective of the study was to investigate whether pre-pandemic leukocyte counts could serve as a predictor for the severity of post-acute sequelae of SARS-CoV-2 infection, commonly known as long COVID, in older women. The key finding was that higher pre-pandemic leukocyte counts were substantially associated with more severe long COVID symptoms.
Editor: What is the importance of leukocyte counts in this context?
Guest: Leukocyte counts are a measure of white blood cells in the body, which are crucial for the immune response. Higher levels can indicate underlying inflammation or heightened immune system activity. Our study suggests that these pre-existing immune system markers can help identify individuals who may be at greater risk for severe long-term COVID-19 complications.
Editor: Were there any unexpected findings or challenges during the research?
Guest: One of the challenges was ensuring the accuracy of pre-pandemic leukocyte counts, as these were recorded before the COVID-19 outbreak. We had to meticulously cross-check and validate the data to ensure reliability. An unexpected finding was the strong correlation between higher leukocyte counts and cognitive impairment,which was more pronounced than we initially hypothesized.
Editor: How could these findings impact the management and treatment of long COVID?
Guest: These findings could revolutionize the way we approach long COVID by enabling early risk identification. Healthcare providers could monitor leukocyte counts and implement preventive measures or tailored treatments for those at higher risk. This could lead to more effective management of symptoms and improved quality of life for patients.
Editor: What are the next steps for this research?
Guest: The next steps include expanding the study to include a more diverse demographic and investigating other potential immune system markers. We also plan to explore how these markers interact with other health conditions and how they can be integrated into routine health assessments to predict and mitigate the risk of severe long COVID.
Editor: How does this study contribute to the broader understanding of long COVID?
Guest: This study adds a critical piece to the puzzle of understanding long COVID by highlighting the role of pre-existing immune system markers. It underscores the importance of considering baseline health metrics in predicting and managing long-term complications of COVID-19, thereby contributing to more comprehensive and personalized healthcare strategies.
Conclusion:
This insightful discussion underscores the importance of pre-pandemic leukocyte counts as a predictor of long COVID severity in older women. By identifying individuals at higher risk, healthcare providers can implement targeted interventions, ultimately improving patient outcomes. The study opens new avenues for research and highlights the need for a more personalized approach to managing long COVID.
