Case series: No complications with Lyme disease and pregnancy

lyme-disease-pregnancy

There is not much information available about the impact of Lyme disease during pregnancy. However, in their article “Case Report: Lyme Borreliosis and Pregnancy - Our Experience,” Trevisan and colleagues share their experience in treating 11 pregnant women with Lyme disease from 2008 to 2020 at Trieste University Hospital. [1]

 

The first confirmed case of LB [Lyme borreliosis] in a pregnant woman was described in 1985 in a 28-year- old mother who was infected with LB in the first trimester and delivered her baby at 35 weeks, the authors explained, based on a paper by Schlesinger et al.²

“The mother developed symptoms consistent with LB post-delivery as documented by a positive immunofluorescence assay for LB. Unfortunately, the child died of congenital heart disease, and the autopsy revealed spirochetes infiltrating the spleen, kidneys, and bone marrow, but not cardiac tissue,” the authors wrote.

“Complications of maternal Lyme borreliosis in pregnancy outcomes have been already reported, including stillbirth and possible congenital malformations,” wrote Trevisan et al.

They point out, “Borrelia specific antibodies have been detected in the cerebrospinal fluid of an infant with documented neurologic dysfunction.”

“Pregnant women are considered a vulnerable group due to a weakened immune system. Therefore, they are more susceptible to infection with an increased risk for severe illness…and infections in pregnant women have the added gravity of potential infection in the developing fetus.”¹

According to the study, which included 11 pregnant women with Lyme disease, 5 women were diagnosed and treated for LB in the first trimester, 3 in the second trimester and the last 3 women in the third trimester of pregnancy.

There was a wide range of clinical presentations, as 6 women developed erythema migrans rash during pregnancy (between week 8 and 34), 3 had myoarticular involvement and 1 exhibited neurological symptoms.

Two of the women had positive serology for LB but did not develop any clinical symptoms. The other patients were positive, except for the 26-year-old patient with erythema migrans.

All the mothers were treated with amoxicillin 1g 3x/day for 14 days.

One child was born prematurely at 7 months. Another child was born with angiomatoid patches that regressed spontaneously 18 months later. All the other babies were born healthy.

At 1-year follow-up, 10 of the women were healthy. One woman with articular and neurological involvement improved partially with amoxicillin but required treatment with intravenous ceftriaxone because of persistent symptoms.

Authors conclude

  • “In pregnant women in endemic areas for Lyme Borreliosis, also testing antibodies against Borrelia should be routinely recommended, in case of positivity the same analysis could also be suggested on umbilical cord blood at delivery.”
  • “Pregnant women with LB should be treated and clinically followed, with particular attention for cutaneous, myoarticular, neurological, ocular and cardiac manifestations, which could require a fetal ECO-cardiography follow-up.”
  • “Newborns should be examined for possible clinical manifestations, as babies born from mothers with gestational LB have been documented in some cases to be small for dates, or presenting several manifestations including pyloric stenosis, cutaneous annular erythemato-papular eruption, cutaneous angiomas, neurological disorders, muscle hypotonia, hypospadias and skeletal abnormality.”

Editor’s note: Although there were no complications reported in this case series, it would be helpful to study gestational Lyme disease. In addition, it would be beneficial to follow cases to ensure no sequelae, i.e., ADHD and Autism.

    My son was born in 1998 with Lyme! I wasn’t aware that I had Lyme while I was pregnant, my pregnancy had many complications including a very long labor(48 hours). My Lyme was diagnosed by my son’s pediatrician Dr. Jones who referred me to a Specialist. My son was diagnosed at 3 weeks old.

    I was 17 weeks pregnant in 2004 and was infected with LB. I was lucky my baby was born but has allergies I or any family member does not. I developed the rash and was given 250 mg of amoxicillin to take once a day. It’s a miracle my son even survived because there were no follow ups on LB treatment for us.
