LYME PODCAST: 74-YEAR-OLD WOMAN WITH A TRIPLE TICK ATTACK

Lyme Disease Podcast: 74-year-old woman with a triple tick attack

Welcome to an Inside Lyme case study. I find that the best way to get to know Lyme disease is through reviewing actual cases. In this case study, I will be discussing a 74-year-old woman with a triple tick attack. This case series will be discussed on my Facebook and made available on podcast and YouTube.

In this episode, I will be discussing a 74-year-old woman with a triple tick attack.

This case was described in the journal Cureus, written by Kumar and colleagues in 2019.

A 74-year-old woman had underlying medical problems.  She was a smoker with chronic obstructive pulmonary disease (COPD). She also had hypertension. She was initially treated for pneumonia with ceftriaxone and azithromycin. She was also treated for Babesia.

Her red blood test contained parasites typical of Babesia.  That is, they were able to see a parasite typical of Babesia under the microscope. Babesia is a disease from a parasite found in a deer tick. This is the same deer tick that carries the spirochete that causes Lyme disease.  Over 9% of her red cells contained parasites typical of Babesia.

The doctors added atovaquone for Babesia.  Atovaquone is marked under the name Mepron in the US. The doctors also added doxycycline over concerns that the woman might also be infected with Lyme disease. She was quite ill.  She was also placed on a respirator.  She required medications to raise her blood pressure.

The doctors prescribed erythrocytapheresis due to the severity of her illness and the high number of parasites in her red cells. During erythrocytapheresis, some of the red blood cells are removed and replaced with blood from a donor. The number of parasites dropped from 9 to 5.54 percent, but the woman remained in shock. Her kidneys function worsened, which was believed due to hemolysis.

The woman’s blood test was positive for Lyme disease and Anaplasmosis.

There have been a number of studies showing three or more pathogenic infections in the same tick. 

The doctor made one last antibiotic change.  The doctors changed the treatment for Babesia from atovaquone and azithromycin to clindamycin and quinine.  Clindamycin and quinine are still used for difficult to treat cases of Babesia. She improved enough to take her off the respirator. Her blood counts and kidney function returned to normal after 14 days of treatment.

There have been a number of studies showing three or more pathogenic infections in the same tick.  “The incidence of a three pathogen infection is rare” writes Kumar. In actual practice, I have seen individuals with three pathogens who have not been published.

I support the Kumar’s call for a low level of suspicion; “A low threshold for suspicion should be held for a co-infection when patients exhibit a presentation that would be atypical for single pathogen exposure. A delay in diagnosis can lead to prolonged disease duration and increases the comorbidities associated with the infectious state.”

I agree with the doctor’s concerns with the reliability of testing for Babesia.  Kumar writes,  “A blood smear is the gold standard for the diagnosis of Babesiosis, however, if a patient has a low level of parasitic load, PCR is more sensitive.”

Kumar also raised concerns about the reliability of testing for Anaplasmosis.  Anaplasmosis has been seen in red cells in some patients.  “PCR and serological testing are also available, which are more sensitive than a thin smear.”

Finally, Dr. Kumar advised a longer course of treatment for Babesia.  “In case of immunocompromised individuals who are at risk of relapsing Babesia, treatment for a total of six weeks is preferred, including a period of two weeks after parasites are no longer visible on a thin smear” writes Kumar.

What can we learn from this case?

  1. It is important to look for a tick-borne infection even in patients with an underlying illness.
  2. Patients can suffer from more than one tick-borne infection at the same time.
  3. Their illness can be severe.

What questions does this case raise?

  1. Would Babesia have been discovered without seeing the parasite under the microscope?
  2. What is the best combination of treatment and length of treatment to prevent long-term complications?

TREATING TICK-BORNE DISEASE IN MY PRACTICE

In my practice, each individual requires a careful assessment. That is why I order tests a broad range of tests, including blood counts, liver and kidney function, thyroid disease, lupus, and rheumatoid arthritis in addition to tests for tick-borne infections. I also arrange consultations such as neurologists, rheumatologists, and ophthalmologists.

Many patients are complex, as highlighted in this Inside Lyme Podcast series.

We need more doctors with skills diagnosing and treating individuals with more than one tick-borne infection. We could use a reliable test to determine who has a tick-borne infection and when tick-borne infections have resolved. We need to determine the best course of treatment to prevent chronic illness. We hope a professional can use this case to remind them to look for more than one tick-borne infection and treat them accordingly.

We also need to give doctors the freedom to treat these difficult cases without undue interference by colleagues, insurance companies, medical societies, and medical boards.

**Comment**

A few details:

  • She was an avid gardner
  • It doesn’t specify if she saw a tick or not.  The title is misleading because it infers she was bitten 3 separate times when in fact 1 tick bite could transmit all 3 pathogens simultaneously.
  • The study states that it is COMMON to be infected with 2 pathogens but that being infected with 3 is rare, but that risk increases in endemic areas (like Wisconsin). It is my experience that infection with 3 pathogens or more in WI is fairly common.
  • Dr. Horowitz recommends treating Babesia for 9 months to a year.  https://madisonarealymesupportgroup.com/2016/01/16/babesia-treatment/
  • They don’t state it but ALL Lyme/MSIDS patients are immunocompromised, which means we typically need longer treatment. Mainstream medicine completely ignores this issue.
  • The study states: A treatment duration of a total of 10 days has been shown to be highly effective in treating both Lyme disease and human granulocytic anaplasmosis [12-13].  I couldn’t disagree more.  The study in reference #12 studied 10 days of treatment to eradicate the EM rash.  It’s common knowledge that the disappearance of EM rash does not mean a systemic infection is eradicated.  In fact, the EM rash has been known to disappear without any treatment what so ever!  The study in reference #13 is really about the increased disease severity in those with Anaplasmosis who had a delay in treatment. The study also admitted that their study may have excluded those with PCR-negative cases as well as the fact they are assuming disease course and severity doesn’t differ with different species.
