Relying on a negative Lyme disease test can prove deadly

In August of 2013, a 17-year-old boy died suddenly from cardiac arrest. Initially, health officials blamed the Powassan virus for his death. But a recent report in Cardiovascular Pathologist finds that the young man died instead from Lyme carditis.

In the summer of 2013, a young man from Poughkeepsie, NY, died suddenly after suffering from flu-like symptoms for nearly 3 weeks. Initial reports suggested he had died from complications due to the Powassan virus, a rare illness, transmitted by ticks that can be fatal.

However, a paper published in the March issue of Cardiovascular Pathologist, 3. reports the adolescent, in fact, had died from Lyme carditis.

Negative Lyme disease tests overshadowed the patient’s clinical symptoms. A diagnosis of Powassan virus was changed to Lyme carditis after the young man’s death.

According to the report, the ELISA and Western blot IgM tests, conducted as part of the autopsy, were positive for Borrelia burgdorferi, the agent that causes Lyme disease. Additional tests, including PCR (polymerase chain reaction) and immonohistochemistry (ICH) staining found Borrelia spirochete present in the patient’s liver, heart, lung, and brain tissues.

“The findings support B. burgdorferi as the causative agent for his fulminant carditis and that the patient suffered fatal Lyme carditis,” the authors write.

The high school honor roll student had aspired to be an environmental engineer and loved the outdoors. He had just returned home from a two-week stay at a camp in Rhode Island, a state that is endemic for Lyme disease, when he fell ill.

According to his parents, he initially developed a mild cough, occasional fevers, a sore throat, malaise, headaches and body aches. Serology tests for Lyme disease and anaplasmosis were negative.

The young man’s symptoms progressed. He complained of gastrointestinal problems, light-headedness and photophobia (light sensitivity). According to the Poughkeepsie Journal, he was instructed to rest and stay hydrated.

A few days later, he collapsed suddenly in his backyard. The young man had gone into cardiac arrest. “Doctors in Westchester tried to diagnose his condition but were stumped,” states the Poughkeepsie Journal. The teenager died several hours later. He was just 17-years-old.

When an individual manifests symptoms consistent with Lyme disease and has been exposed to a tick endemic region, clinicians should consider a Lyme disease diagnosis, even with a negative test result.

Because Lyme disease symptoms are often compared to those of the flu, people may tend to equate the two illnesses, and mistakenly assume that Lyme disease is harmless. That is not necessarily the case. If the infection is not treated appropriately in its initial stage, the disease can progress, causing debilitating symptoms, chronic illness and, in rare cases, fatalities.

What is Lyme carditis?

Lyme carditis occurs when the Lyme spirochete (Borrelia burgdorferi) enters the heart tissue. It is considered rare with only a handful of fatalities reported. The condition can be extremely challenging to diagnose, since patients typically describe classic flu-like symptoms. In fact, one study found 94% of patients with Lyme carditis exhibited nonspecific symptoms, including fever, malaise, headache, arthralgia, and/or myalgias. 1

Children and adolescents can also be affected. A 2009 study in Pediatrics, Lyme carditis in children: presentation, predictive factors and clinical course, evaluated 207 pediatric patients with early disseminated Lyme disease and found that 16% had Lyme carditis, 42% of those patients had advanced heart block, with 27% exhibiting complete heart block and 4 patients with severely depressed systolic ventricular function. 1

While Lyme carditis may be rare, this young man’s tragic death illustrates the potential dangers of relying on serology tests to diagnose and treat Lyme disease.  It also underscores the ongoing confusion among clinicians over the accuracy and reliability of such tests, specifically the ELISA and Western blot.

The young man appeared to fit the requirements for a Lyme disease diagnosis. He had the typical symptoms associated with Lyme – fatigue, headaches, body aches, GI disruptions, fevers, light sensitivity – and he had visited a tick endemic region with a high probability for exposure to ticks.

Furthermore, he lived in Dutchess County, New York, an area that’s endemic for Lyme disease with an estimated 50% of deer ticks infected with the Lyme organism.

Yet, the young man was not diagnosed, nor treated for Lyme disease. It is unfortunate that his negative test results overshadowed his clinical symptoms and history.

The Centers for Disease Control and Prevention (CDC) point out that patients tested during the first few weeks of illness often test negative, because there’s not enough antibodies in the bloodstream to be detected. The ELISA and Western blot can miss up to 60% of well-defined Lyme disease cases. 2

Physicians who treat Lyme disease according to guidelines put forth by the International Lyme and Associated Diseases Society (ILADS) are encouraged to treat patients based on clinical judgment even when tests are negative.

    3 years ago I woke up with such a sore stiff neck, and then then very next morning had a bulls eye rash on my shoulder, I was sick with flu like symptoms fever exaughtion ,muscle aches, headache and light hurt my eyes terribly. I did not go to the doctor, but have since suffered from severe headaches depression mind fog, confusion, dizziness. I went in for test Lyme and it came back negative. I am really concerned what to next

      You should include an evaluation by a doctor experienced in evaluating tick borne illnesses.

    Hi. I have had Lyme carditis. The hospital MRI images showed where spirochetes had seeded into my heart valves. Decades later I now have both Bradycardia at age 60 and also “LBBB” — aka Left Bundle Branch Block. Dr. Cameron saw me at age 31. I was multiply infected way back then! Now even after IV Picc therapies with Rocephin and Claforan and years of oral combination ABX Lyme protocols…My Cardiologist informed me that I have no functioning pacemaker cells on the left side of my heart. Thanks to the denial of a prompt diagnosis and denial of antibiotics by stubbornly ignorant Tennessee physicians.

    Thank you for creating this blog and thank you for the article on Joseph Elone. I followed the articles on him when they first came out and am disgusted that he was not treated for lyme right away. We have many children dying from Rocky Mountain Spotted Fever in the South and many are dying from the long term effects of not being treated for tick borne and other vector borne pathogens. We need to research the pathogens within people and then figure out the most efficacious medications to deal with those infectious agents. IDSA guidelines are useless and we need to come up with a better methodology for treating very ill people. Prophylactic antibiotic treatment should be the norm and we have IDSA physicians taking a wait and see approach when people are bitten by ticks.

    I was diagnosed by cardiac arrest in 2013. I have a pacer and brain fog,fatigue, nausea,poor memory and no focus, concentration. As well as bilateral arm and shoulder pain. I applied for std and was denied they say it is preexisting. I was dx on 7/30/13 the cut off is July 1 2013. I must of had Lyme for quite sometime before I was diagnosed. What are your thoughts?
