Abstract

Bartonella endocarditis can be a very elusive diagnosis. The clinical manifestations can vary and, at times, include multiorgan involvement. This case report describes two patients presenting with multiorgan failure, cerebral mycotic aneurysms and valvular endocarditis secondary to Bartonella infection. The complex diagnosis, decision making, and surgical management are described.

**Comment**

It’s unfortunate that once again the study authors choose the word “rare” regarding Bartonella and/or any tick-borne infection manifestations, as even the most hardened critics admit these pathogens are prevalent and can have highly variable presentations. It would have been much more appropriate that the authors would state it’s the first time these particular findings have been published rather than give people the impression something occurs rarely.

Lyme patients and the doctors treating this appropriately are acutely aware of potential heart involvement:  https://madisonarealymesupportgroup.com/2019/06/04/how-vector-borne-diseases-impact-heart-health/

Again, please keep in mind that current 2-tiered CDC testing is based on blood tests that misses half of all cases and do not look for the organism but the body’s immune response (antibodies):  https://madisonarealymesupportgroup.com/2018/12/16/laboratory-testing-for-lyme-disease/  Current CDC guidelines were created for surveillance purposes only but are being used diagnostically. All patients should be informed that they can still be infected despite a negative test. 

Also, please be aware of the conflicts of interest regarding patents on testing:  https://madisonarealymesupportgroup.com/2019/06/28/who-owns-the-elisa-patents/

There are going to be patients with heart symptoms that have an underlying tick-borne illness but test negatively (seronegative). These people are falling through the cracks of the medical symptom yet could be greatly helped with appropriate antimicrobial treatment. If you suspect you are one of these people or suspect others, please give the validated Horowitz questionnaire to them to take to their practitioner:  https://madisonarealymesupportgroup.com/2017/09/05/empirical-validation-of-the-horowitz-questionnaire-for-suspected-lyme-disease/ It also takes an open mind and trained eye to diagnose these patients, and it can be Lyme, Baronella, or any one of many pathogens transmitted by ticks:  https://madisonarealymesupportgroup.com/2019/08/22/early-diagnosis-necessitates-lyme-savvy-doctors/  I hope doctors are waking up to the growing need for education regarding the growing link between tick-borne illness and heart issues.

Endocarditis caused by Bartonella Quintana, a rare case in the United States

Abstract

Bartonella quintana is a relatively rare cause of endocarditis in the United States (USA). Historically it was linked with trench fever, but cardiac involvement seems to be more prevalent recently. There are some known risk factors associated with Bartonella quintana endocarditis such as human immunodeficiency virus (HIV) infection, alcoholism, homelessness and poor hygiene. We report a case of 37-year-old African man, with culture negative endocarditis, emboli and rising B. quintana and B. henselae IgG titers. B. quintana DNA was subsequently detected from the mitral valve sample with 16S rRNA gene and ribC primer sets. Eventually, blood culture for B. quintana was positive after 21 days. Patient was successfully treated with doxycycline and gentamicin. There have been a few cases of B. quintana endocarditis in the USA and most of them were associated with HIV infection, homelessness or alcoholism. The case reported here highlights the importance of high clinical suspicious for Bartonella species in blood culture negative endocarditis in the USA in appropriate setting and will help to increase awareness among physicians for early diagnosis and treatment.

Tick-borne Pathogens Bartonella spp., Borrelia Burgdorferi Sensu Lato, Coxiella Burnetii & Rickettsia Spp. May Trigger Endocarditis

https://www.ncbi.nlm.nih.gov/pubmed/31374162/

2019 Jul;28(7):957-963. doi: 10.17219/acem/94159.

Tick-borne pathogens Bartonella spp., Borrelia burgdorferi sensu lato, Coxiella burnetii and Rickettsia spp. may trigger endocarditis.

Abstract

BACKGROUND:

Infections caused by tick-borne pathogens such as Bartonella spp., Borrelia burgdorferi s.l., Coxiella burnetii and Rickettsia spp. are capable of causing serious lesions of the mitral and aortic valves, leading to a need for valve replacement.

OBJECTIVES:

The aim of the study was to determine whether such cases are sporadic or frequent. An additional goal was to establish effective diagnostic methods to detect these infections.

MATERIAL AND METHODS:

The study involved 148 patients undergoing valve replacement. Blood samples were drawn for serological testing. Samples of the removed mitral and aortic valves were tested with PCR and immunohistochemical staining.

RESULTS:

Specific antibodies to

  • Bartonella spp. were detected in 47 patients (31.7%) and in 1 of the healthy controls (1%) (p < 0.05)
  • B. burgdorferi spirochetes were found in 18 of the patients (12.2%) and in 6 blood donors from the control group (5.8%) (p < 0.1)
  • Rickettsia spp. were detected in 12 (8.1%) 
  • C. burnetii phase I and II antigens in the serum of 1 patient. All the participants in the control group were seronegative to C. burnetii and Rickettsia spp. antigens.
  • PCR tests for detection of Bartonella spp., B. burgdorferi s.l., C. burnetii and Rickettsia spp. DNA in the valve samples were all negative.

Inflammation foci with mononuclear lymphoid cells in the aortic and mitral valves were seen in sections stained with hematoxiline and eozine. In sections dyed using the indirect immunofluorescence method with hyperimmune sera, Bartonella spp. and Rickettsia spp. were found.

CONCLUSIONS:

The results obtained indicate that laboratory diagnostics for patients with heart disorders should be expanded to include tests detecting tick-borne zoonoses such as bartonelloses, Lyme borreliosis, rickettsioses and Q fever.

**Comment**

This article shows that tick borne pathogens are common with patients needing heart valve replacements. Unfortunately, testing still isn’t accurate. Finding antibodies, authorities would argue, doesn’t mean a person has symptoms; however, this issue desperately needs further research as finding antibodies does indicate the presence of pathogens.

A point to be made about the low percentage of those testing positive for Lyme might be due to the fact they only tested one strain: Borrelia burgdorferi sensu lato.  There are 300 strains worldwide and 100 in the U.S. (and counting).

Bartonella is similar in the fact that a recent article pointed out that a 14-year-old boy with PANS caused by Bartonella henselae infection was NOT seropositive. Only one of the three blood samples tested positive before culturing and only two tested positive after culturing. A single blood draw might have missed confirming a diagnosis of bartonellosis.

How many doctors are going to hunt these infections to ground? How many have the time and doggedness it requires to find them? It’s far more likely they will take the results from a singular test, close the book, and move onto the next patient.

We desperately need accurate tests that pick up ALL the pathogens.

 

 

 

Infective Endocarditis Without Biological Inflammatory Syndrome: Description of a Particular Entity

https://www.ncbi.nlm.nih.gov/pubmed/31303461

2019 Jul 11. pii: S1875-2136(19)30078-6. doi: 10.1016/j.acvd.2019.02.005. [Epub ahead of print]

Infective endocarditis without biological inflammatory syndrome: Description of a particular entity.

Abstract

BACKGROUND:

Bacterial infective endocarditis (IE) is rarely suspected in patients with a low C-reactive protein (CRP) concentration.

AIMS:

To address the incidence, characteristics and outcome of left-sided valvular IE with low CRP concentration.

METHODS:

This was a retrospective analysis of cases of IE discharged from our institution between January 2009 and May 2017. The 10% lowest CRP concentration (<20mg/L) was used to define low CRP concentration. Right-sided cardiac device-related IE, non-bacterial IE, sequelar IE and IE previously treated by antibiotics were excluded.

RESULTS:

Of the 469 patients, 13 (2.8%; median age 68 [61-76] years) had definite (n=8) or possible (n=5) left-sided valvular IE with CRP<20mg/L (median 9.3 [4.7-14.2] mg/L). The median white blood cell count was 6.3 (5.3-7.5) G/L. The main presentations were heart failure (n=7; 54%) and stroke (n=3; 23%). Transthoracic echocardiography (TTE) showed vegetations (n=5) or isolated valvular regurgitation (n=4). Overall, eight patients (62%) had severe valvular lesions on transoesophageal echocardiography (TOE), and nine patients (69%) underwent cardiac surgery. All patients survived at 1-year follow-up. Bacterial pathogens were documented in eight patients using blood cultures, serology or valve culture and/or polymerase chain reaction analysis.

  • streptococci
  • coagulase-negative Staphylococcus
  • Corynebacterium jeikeium
  • HACEK group (Haemophilus, Aggregatibacter, Cardiobacterium, Eikenella, Kingella)
  • Coxiella burnetii
  • Bartonella henselae

CONCLUSIONS:

Left-sided valvular IE with limited or no biological syndrome is rare, but is often associated with severe valvular and paravalvular lesions. TOE should be performed in presence of unexplained heart failure, new valvular regurgitation or cardioembolic stroke when TTE is insufficient to rule out endocarditis, even in patients with a low CRP concentration.

**Comment**

A low CRP concentration means there isn’t inflammation. Typically, bacterial infections raise CRP, so this study is important because it shows that patients can be infected but NOT have a high CRP.

Regarding Coxiella burnetti, or Q-Fever:

https://madisonarealymesupportgroup.com/2019/02/14/impact-of-pre-operative-antimicrobial-treatment-on-microbiological-findings-from-endocardial-specimens-in-infective-endocarditis/

The brown dog tick, Rocky Mountain Wood tick, and the Lone Star Tick are all vectors and Q-fever is endemic throughout the U.S.  Treatment is doxycycline.

https://phc.amedd.army.mil/PHC%20Resource%20Library/QFever_FS_18-048-0317.pdf  This document states Q-Fever is a category B agent (moderately easy to disseminate).

Humans are very susceptible to the disease and few organisms are required to cause
infection. In rare instances, people may acquire Q fever via the ingestion of raw milk or eggs, by tick bites, or by human-to-human transmission.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC88923/  Interestingly, even as far back as the 30’s, Q-fever was noted to have properties of both viruses and rickettsiae. This document states Q fever may occur in patients without any animal contact due to it’s ability to be spread by wind.  The same document states human Q-fever cases have occurred in the following:

  • An OB after an abortion on an infected woman
  • transplacental transmission
  • autopsies
  • intradermal inoculation
  • blood transfusion
  • tick bite
  • sexually in infected mice
  • possibly from infected dogs
  • infected cats

The real kicker on that last one was the 1984 report of 13 people who developed febrile respiratory disease by playing poker in a room where a cat had delivered kittens.  Abstract here:

Kosatsky T. Household outbreak of Q-fever pneumonia related to a parturient cat. Lancet. 1984;ii:1447–1449. [PubMed]

Symptoms were:

  • bradycardia (slow heart rate)
  • fever
  • palatal petechiae (red or purple spots on mouth palate)
  • rapidly enlarging bilateral pulmonary infiltrates (fluid in both lungs)
