Mast cell activation syndrome develops for a reason. There is often an insult to a tissue rich in mast cells, whether the gut, nervous system, brain, vascular space, skin, or even bone. Combined with pre-existing factors like genetics or prior infections, the mast cells become primed for overreaction.
It does not happen randomly. An insult occurs, the body responds, and in some patients that response never turns off. Identifying the original trigger, or the factors keeping the system activated, is part of understanding why MCAS developed in the first place.

Spring is here and as you step outside, ticks are already active. A tick bite does not necessarily mean an infection was transmitted, but knowing what to do and when to test can help you stay ahead of potential complications.
If you do not save the tick, timing matters for testing. Antibody tests are more reliable about three weeks after the bite, as your immune system needs time to respond. PCR tests, which look for bacterial DNA, are more likely to detect infection during the first week or two. There are many opinions on when and how to treat, and consulting a Lyme literate practitioner is the best way to discuss the safest option for you.
Early treatment can make a big difference in long-term health. Save and share this post for tick season.

In the early phases of Lyme, it is primarily an infection issue. If you can catch it within the first year or treat it at the time of exposure, the focus is on addressing the bacteria. The longer it goes on, the picture changes.
Chronic Lyme is not always driven by the infection itself. Over time, it creates the conditions for immune dysregulation, and that becomes the bigger problem. Predisposing factors like genetics, toxic burden, or previous infections can also play a role in how the immune system responds.
This is why treatment for someone who just got bit looks very different from treatment for someone who has been sick for years.

The most reliable lab for tickborne disease testing depends on how long you have been sick. In the first year of illness, or right after a tick bite, classical antibody testing like Western blots and serology can work well. The immune system is still actively responding and those signals are detectable.
The longer someone is sick, the more complicated it becomes. Antibody signals may not be as reliable in chronic patients who have developed some level of immune dysregulation. In those cases, direct testing like PCR, DNA, RNA, or culture enhanced analysis may be needed to find the presence of an infection that standard tests miss.
If your Lyme test came back negative but you still have symptoms, timing and test type may be the issue.

There are multiple interventions being studied to prevent Long COVID, yet none of them have been shown to work across the board. Metformin has shown promise in some patients, early treatment with Paxlovid may help, and adequate vitamin D levels appear to be protective. There are many other interventions being explored, yet none of them work for everyone.
This is the challenge with Long COVID. It is not one condition with one cause, which means prevention strategies vary from person to person depending on their individual risk factors and immune status.

For many patients, Long COVID is an autoimmune condition in the sense that the body is now producing elevated levels of autoantibodies to autonomic tissues. This can be measured in blood tests and helps explain why symptoms persist long after the initial infection.
In some cases, plasmapheresis can offer temporary relief by removing these autoantibodies from circulation. The challenge is that the response will be short-lived if the triggering elements are not also addressed. Identifying and removing what is driving the autoimmune response is essential for lasting improvement.
Comment PLASMA and we will send you more information on how plasmapheresis may support Long COVID recovery.
