Bartonella infections diagnosed in the French reference center, 2014-2019, and focus on infections in the immunocompromised.

Eur J Clin Microbiol Infect Dis 2021 Apr 12. Epub 2021 Apr 12.

Centre National de Référence des Rickettsies, Coxiella et Bartonella IHU-Méditerranée Infection, APHM, Marseille, France.

We studied retrospectively 651 PCR-confirmed Bartonella infections diagnosed at the French reference center for bartonellosis from 2014 to 2019. The most common form was cat-scratch disease (89%) followed by endocarditis (9%). Disseminated forms (2%) mainly presented as bacillary angiomatosis or peliosis hepatis in solid organ transplant recipients. Read More

Recurrent Gastrointestinal Bleeding in an HIV-Positive Patient: A Case Report.

Cureus 2020 Sep 27;12(9):e10688. Epub 2020 Sep 27.

Department of Gastroenterology, Istanbul Medeniyet University, School of Medicine, Istanbul, TUR.

HIV is a global epidemic that needs a multidisciplinary approach. Gastrointestinal bleeding is uncommon in HIV-positive patients. In cases such as bacillary angiomatosis, Kaposi sarcoma, herpes simplex, histoplasmosis, and cytomegalovirus (CMV) colitis, the underlying reason could be HIV. Read More

Bacillary angiomatosis triggered by severe trauma in a healthy Caucasian patient: A case report.

Exp Ther Med 2020 Jul 29;20(1):56-60. Epub 2019 Nov 29.

Department of Dermatology, Derma 360° Clinic, Bucharest 011273, Romania.

Bacillary angiomatosis represents a cutaneous and systemic infection caused by species, typically described in the past in HIV-positive patients or associated with immunodeficiencies. More recent case reports had brought into attention the probability that this entity may manifest in otherwise healthy individuals, triggered by trauma and skin burns. The physiopathology of this neoproliferative process is based on the production of angiogenetic molecules, such as vascular endothelial growth factor (VEGF) and IL-8. Read More

Doxycycline, an Antibiotic or an Anti-Inflammatory Agent? The Most Common Uses in Dermatology.

Actas Dermosifiliogr 2020 Sep 13;111(7):561-566. Epub 2020 May 13.

Unidad de Dermatología Médico-Quirúrgica y Venereología, Hospital Universitario San Cecilio, Granada, España.

Doxycycline is a synthetic tetracycline that was approved in 1967. This wide-spectrum antibiotic has been shown to also have useful anti-inflammatory properties that make it suitable for the treatment of a number of noninfectious conditions. Tetracyclines are probably the most commonly prescribed antibiotics in dermatology, where they are usually used at doses lower than those effective against infections. Read More

BMC Infect Dis 2020 Mar 12;20(1):216. Epub 2020 Mar 12.

Division of Bacterial Disease Research, Center for Infectious Disease Research, Korea National Institute of Health, Chungcheongbuk-do, Korea.

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. Read More

Bartonella henselae is a facultative intracellular pathogen that occurs worldwide and is responsible primarily for cat-scratch disease in young people and bacillary angiomatosis in immunocompromised patients. The principal source of genome-level diversity that contributes to B. henselae's host-adaptive features is thought to be horizontal gene transfer events. Read More

Bartonella infections in cats and dogs including zoonotic aspects.

Parasit Vectors 2018 Dec 4;11(1):624. Epub 2018 Dec 4.

Departament de Medicina i Cirurgia Animals, Facultat de Veterinària, Universitat Autònoma de Barcelona, 08193, Bellaterra, Spain.

Bartonellosis is a vector-borne zoonotic disease with worldwide distribution that can infect humans and a large number of mammals including small companion animals (cats and dogs). In recent years, an increasing number of studies from around the world have reported Bartonella infections, although publications have predominantly focused on the North American perspective. Currently, clinico-pathological data from Europe are more limited, suggesting that bartonellosis may be an infrequent or underdiagnosed infectious disease in cats and dogs. Read More

Cat-Scratch Disease in an AIDS Patient Presenting with Generalized Lymphadenopathy: An Unusual Presentation with Delayed Diagnosis.

Am J Case Rep 2018 Aug 2;19:906-911. Epub 2018 Aug 2.

Department of Internal Medicine, Icahn School of Medicine at Mount Sinai, New York, NY, USA.

BACKGROUND Bartonella infection is the causative organism of cat-scratch disease (CSD), which typically presents with self-limited localized lymphadenopathy. In HIV-infected patients, Bartonella infection can cause systemic illnesses with significant morbidity and mortality manifesting as bacillary angiomatosis (BA), hepatic peliosis, splenitis, bacteremic febrile illness, and other organ involvement. To the best of our knowledge, there have been no reports of HIV-infected patients presenting with generalized lymphadenopathy caused by Bartonella infection. Read More

Bartonella henselae in small Indian mongooses (Herpestes auropunctatus) from Grenada, West Indies.

Vet Microbiol 2018 Mar 9;216:119-122. Epub 2018 Feb 9.

Anatomy, Physiology, and Pharmacology Academic Program, School of Veterinary Medicine, St. George's University, St. George's, Grenada, West Indies.

Many mammals are established hosts for the vector borne bacterial genus, Bartonella. Small Indian mongooses (Herpestes auropunctatus) have only been reported as a possible host for Bartonella henselae in southern Japan. Confirming Bartonella presence in mongooses from other regions in the world may support their role as potential reservoirs of this human pathogen. Read More

Department of Clinical Sciences, Comparative Medicine Institute, College of Veterinary Medicine, North Carolina State University, Raleigh, NC, USA.

Ineffective erythropoiesis was diagnosed in an 8-year-old male castrated Labrador Retriever. Despite treatment with immunosuppressive therapy for suspected immune-mediated erythrocyte maturation arrest, resolution of the nonregenerative anemia was not achieved. Following documentation of Bartonella henselae bacteremia by Bartonella alpha proteobacteria growth medium (BAPGM) enrichment blood culture, immunosuppressive therapy was discontinued, and the anemia resolved following prolonged antibiotic therapy.
