Unusual Subdural Empyema in a Homeless Patient Diagnosed by Molecular Approach: A Case Report

Affiliations expand

Abstract

Background: We report a case of subdural empyema in a homeless patient caused by Bartonella quintana. B. quintana is a facultative intracellular bacteria for which bacterial growth is fastidious. The molecular biology approach has been a real help in establishing the diagnosis.

Case report: A 59-years old homeless patient, with a history of chronic alcohol abuse, was brought to the emergency department with a massive subdural empyema. Extensive microbiological evaluation didn’t reveal any pathogen in the pus collected before antibiotic treatment. B. quintana was detected in the pus from the empyema using a 16S rRNA-based PCR. Histology of intraoperative samples was consistent with the diagnosis and a serological assay was positive. The patient responded well to a treatment that included craniectomy with drainage of the loculated pus, total removal of the infected capsule and a combination of antibiotics.

Conclusion: This unique case of B. quintana-related empyema illustrates the risk of secondary infection of subdural hematoma with B. quintana since such infections have recently reemerged, predominantly among the homeless populations. Patients with subdural empyema in at-risk populations should be systematically evaluated for B. quintana with an appropriate diagnostic approach involving molecular biology.

Ocular Complications of Cat Scratch Disease

https://www.ncbi.nlm.nih.gov/pubmed/32122915/

Ocular complications of cat scratch disease.

Abstract

Cat scratch disease (CSD) in humans is caused by infection with Bartonella henselae or other Bartonella spp. The name of the disease reflects the fact that patients frequently have a history of contact (often involving bites or scratches) with infected cats. Patients with CSD typically develop lesions at the site where the skin is broken together with regional lymphadenopathy but may go on to exhibit systemic symptoms and with deep-seated infections at a range of sites including the eye. Patients with CSD may present with a range of inflammatory eye conditions, including Parinaud’s oculoglandular syndrome, neuroretinitis, multifocal retinitis, uveitis and retinal artery occlusion. Bartonella spp. are fastidious bacteria that are difficult to culture from clinical specimens so microbiological diagnosis is frequently made on the basis of positive serology for anti-Bartonella antibodies or detection of bacterial DNA by PCR. Due to the lack of clinical trials, the evidence base for optimal management of patients with CSD-associated eye infections (including the role of antibiotics) is weak, being derived from single reports or small, uncontrolled case series.

Bartonella Case – Eschar & Enlarged Lymph Nodes

https://www.ncbi.nlm.nih.gov/pubmed/32164559

Scalp eschar and neck lymphadenopathy after tick bite (SENLAT) caused by Bartonella henselae in Korea: a case report.

Abstract

BACKGROUND:

Tick-borne lymphadenopathy (TIBOLA) is an infectious disease, mainly caused by species from the spotted fever group rickettsiae and is characterized by enlarged lymph nodes following a tick bite. Among cases of TIBOLA, a case of scalp eschar and neck lymphadenopathy after tick bite (SENLAT) is diagnosed when an eschar is present on the scalp, accompanied by peripheral lymphadenopathy (LAP). Only a few cases of SENLAT caused by Bartonella henselae have been reported.

CASE PRESENTATION:

A 58-year-old male sought medical advice while suffering from high fever and diarrhea. Three weeks before the visit, he had been hunting a water deer, and upon bringing the deer home discovered a tick on his scalp area. Symptoms occurred one week after hunting, and a lump was palpated on the right neck area 6 days after the onset of symptoms. Physical examination upon presentation confirmed an eschar-like lesion on the right scalp area, and cervical palpation revealed that the lymph nodes on the right side were non-painful and enlarged at 2.5 × 1.5 cm. Fine needle aspiration of the enlarged lymph nodes was performed, and results of nested PCR for the Bartonella internal transcribed spacer (ITS) confirmed B. henselae as the causative agent.

CONCLUSION:

With an isolated case of SENLAT and a confirmation of B. henselae in Korea, it is pertinent to raise awareness to physicians in other Asian countries that B. henselae could be a causative agent for SENLAT.

Brain Aneurysm Caused By Bartonella

Mycotic Aneurysm of the Middle Cerebral Artery Leading to Subarachnoid Hemorrhage, as the Initial Presentation of Bartonella henselae Endocarditis.

Abstract

Bartonella species was first reported as a cause of endocarditis in 1993, currently it is thought to account for 3-4 percent of all diagnosed cases. Initial symptoms of Bartonella endocarditis are non-specific like weight loss, fever and fatigue. There are very few reported cases of Bartonella endocarditis causing mycotic aneurysm.

We present a case of a 60-year-old male who presented with subarachnoid hemorrhage secondary to mycotic aneurysm. Due to high suspicion of endocarditis leading to mycotic aneurysm he underwent transesophageal echocardiography which showed mitral valve vegetations. His blood cultures were negative, he was eventually diagnosed with Bartonella henselae by elevated IgG titers greater than 1:800. Due to repeated mycotic aneurysms on antibiotics, he underwent surgical mitral valve replacement along with the full course of antibiotics and has been asymptomatic since.

A mycotic aneurysm is an aneurysm caused by the growth of fungi or bacteria within the vascular wall, usually following impaction of a septic embolus.  https://medical-dictionary.thefreedictionary.com/mycotic+aneurysm

In this case, Bartonella is the culprit and the patient presented with bleeding in the brain.

Please note the blood culture was negative.

Also note the “repeated mycotic aneurysms on antibiotics.”  I’m not pointing this out to avoid antibiotics but to show that there can be side-effects of treatment.
