Nothing is known about how pathogenic bacteria affect myeloid cells in these processes. Read More

    Bartonella henselae infection-associated vasculitis and crescentic glomerulonephritis leading to renal allograft loss.
    Transpl Infect Dis 2015 Jun 1;17(3):411-7. Epub 2015 Jun 1.
    Department of Pathology, University of Maryland School of Medicine, Baltimore, Maryland, USA.
    Bartonella henselae (BH) is the main cause of cat scratch disease (CSD), which more typically presents as a self-limited localized suppurative lymphadenopathy in immunocompetent individuals. In contrast, immunocompromised patients commonly have systemic disease with life-threatening complications. In addition to the angioproliferative lesions, such as bacillary angiomatosis, an increasing number of immune post-infectious complications are being recognized with BH infections, including glomerulonephritis, vasculitis, hemophagocytic syndrome, and neurological problems.
