“…Non-specific symptoms, including fever, fatigue, and weight loss are observed in most patients [ 7 , 9 ]. The diagnosis of Bartonella endocarditis is challenging since the organism is difficult to isolate using standard microbiologic culture techniques [ 11 , 12 ] and serologic tests are usually used in clinical practice. In a case series comprising 740 patients with blood culture-negative endocarditis in France, Bartonella infections were identified in 80 (22.5%) patients by indirect immunofluorescence assay of IgG antibodies against B. quintana and B. henselae (titers ≥1: 800) [ 10 ].…”

Bartonella is among the most common causes of culture-negative infective endocarditis, with B. henselae being one of the most frequently reported species. The clinical presentation of Bartonella endocarditis is similar to that of subacute bacterial endocarditis caused by other bacteria and the diagnosis can be challenging since the organism is difficult to isolate using standard microbiologic culture techniques. In clinical practice, Bartonella endocarditis is usually diagnosed based on serology. To date, only a handful of cases of infective endocarditis caused by Bartonella have been reported in Thailand. Here, we report the case of 51-year-old Thai male with B. henselae endocarditis with dissemination to the lungs, bones, subcutaneous tissue, epididymis, and lymph nodes with a successful outcome.

“…41 However, c-ANCA directed against PR-3 positivity has also been well documented in infectious endocarditis 42–46 and more specifically in Bartonella endocarditis. 3,5,9–11,26,27,47 The presence of c-ANCA in infectious endocarditis is unclear: it may represent a false-positive or related to the infection or the production of c-ANCA may be induced through B-cell activation after release of PR-3 from neutrophils. 43,48 …”

Among culture-negative endocarditis in the United States, Bartonella species are the most common cause, with Bartonella henselae and Bartonella quintana comprising the majority of cases. Kidney manifestations, particularly glomerulonephritis, are common sequelae of infectious endocarditis, with nearly half of all Bartonella patients demonstrating renal involvement. Although a pauci-immune pattern is a frequent finding in infectious endocarditis–associated glomerulonephritis, it is rarely reported in Bartonella endocarditis. Anti–neutrophil cytoplasmic antibody (ANCA) positivity can be seen with many pathogens causing endocarditis and has been previously reported with Bartonella species. In addition, ANCA-associated vasculitis can also present with renal and cardiac involvement, including noninfectious valvular vegetations and pauci-immune glomerulonephritis. Given the overlap in their clinical presentation, it is difficult to differentiate between Bartonella endocarditis and ANCA-associated vasculitis but imperative to do so to guide management decisions. We present a case of ANCA-positive Bartonella endocarditis with associated pauci-immune glomerulonephritis that was successfully treated with medical management alone.

“…Concurrent administration of immunosuppressive drugs as used in this dog may decrease antimicrobial efficacy, resulting in an incomplete treatment response. Also, therapeutic suppression of the innate immune response may contribute to the development of pathology, such as endocarditis or bacillary angiomatosis in dogs or people that are occultly infected with a Bartonella sp . Based upon a growing body of case‐based evidence, infection with a Bartonella spp .…”
