Understanding Your Body's Defense System: Why Are Blood Cancer Patients at Risk of Infection?

When you're dealing with blood cancer, your body's natural defense system – the immune system – may not be working at full strength. This could be due to recent treatments or changes in your white blood cell counts. Several factors can affect how vulnerable you might be to infections:

• Your immune system's current strength, particularly regarding T-cells (important defender cells in your body)
• Recent treatments like chemotherapy or immunotherapy that temporarily lower your immune response
• For those who've had a transplant, factors like the type of transplant, donor matching, and any graft-versus-host disease (GvHD) can affect your immunity

How to Protect Your Respiratory System? 

During winter, respiratory tract infections become especially common as many spread through the air via tiny droplets from coughs, sneezes, or even regular breathing. Three main viruses we need to watch out for are:

• Respiratory syncytial virus (RSV)
• Influenza (flu)
• Parainfluenza viruses 

For many patients, vaccination (when appropriate) and early antiviral treatment are key tools in preventing complications. However, whether vaccination is currently an option for you or not, there are several effective ways to protect yourself and others during holiday gatherings:

1. Practice Good Hand Hygiene
   • Wash hands thoroughly for at least 20 seconds with antibacterial soap
   • Use alcohol-based hand sanitizer (at least 60% alcohol) when soap isn't available
   • Make hand washing the first thing everyone does when arriving at a gathering
2. Use Masks When Needed
   • Wear a mask if you or others have any respiratory symptoms
   • Remember: what might be a mild cold for one person could develop into severe pneumonia for someone with a compromised immune system
3. Improve Air Quality
   • Ensure good ventilation by opening windows periodically for fresh air
   • Set your home's fan to "on" instead of "auto" when hosting visitors
   • Use pleated filters in your heating/air conditioning systems
   • Replace filters every three months (or as recommended by the manufacturer) to prevent buildup of humidity, mold, and bacteria

What are Common Viral Infections in Blood Cancer Patients? 

It is more common to have a viral infection, as many of these are completely dependent on a weak immune system to develop. That's why these infections are present in many people and tend to appear when the body is more susceptible to infections: 

• Herpes Simplex Virus (HSV): Reactivation of HSV occurs in 15-90% of patients, with symptoms ranging from lesions in the skin or mucous, like the mouth or the eyes, to invasive infections. Antiviral prophylaxis with acyclovir or valacyclovir is effective, but resistance may require alternative therapies like foscarnet or cidofovir.

• Varicella-Zoster Virus (VZV): This virus causes chickenpox and shingles, with reactivation occurring in 2-60% of patients, depending on treatment intensity. Prevention involves antiviral prophylaxis, but individual risk factors must guide the duration of therapy.

• Cytomegalovirus (CMV): CMV can lead to more serious conditions, such as pneumonia, enteritis, and retinitis. Diagnostic advances, including PCR-based techniques, aid in early detection. Prophylactic and preemptive antiviral therapies are pivotal, and new agents like maribavir show promise in reducing CMV incidence.

• Human Herpesvirus-6 (HHV-6): Reactivation in transplant recipients can cause central nervous system dysfunction and delayed platelet recovery. Diagnosis relies on PCR, with foscarnet and ganciclovir being potential treatments.

• Adenovirus: Associated with pneumonia and gastrointestinal disease, adenovirus infections are severe in T-cell–depleted patients. Treatment options include antiviral agents, though more research is needed to refine strategies.
• COVID-19: This virus has been present since the global pandemic, and now, it has a vaccine. Although known, it's worth mentioning that this virus affects the respiratory tract and sometimes the gastrointestinal system. It can also cause unspecific symptoms such as fatigue and fever/chills.

How Can Your Healthcare Team Help? 

Your healthcare provider can help you have a safe holiday with prevention strategies like a vaccination plan, prophylaxis, or supportive measures that help boost your immune system. These strategies include: 

• Antiviral prophylaxis, such as acyclovir, valacyclovir, and ganciclovir, is effective. The duration should be tailored to individual risk profiles.

• Molecular diagnostics: PCR and antigen-based assays enable early detection, guiding timely interventions.

• Emerging therapies: New agents, such as maribavir for CMV, show the potential to improve outcomes.

• Supportive care: Regular monitoring for infections and maintaining robust infection control practices are essential.

Taking Care of You This Season

While the winter holidays bring special moments with loved ones, they also remind us how important it is to protect our health, especially for those affected by blood cancer. By following these prevention strategies, you and your family can focus more on creating precious memories and less on health concerns.

Remember, staying informed is one of the best ways to take control of your health journey. We're here to support you with more resources on staying healthy during treatment.
