    [Dermatologic manifestations associated with HIV/AIDS].
    Rev Chilena Infectol 2015 Feb;32 Suppl 1:S57-71
    The ongoing human immunodeficiency virus (HIV) infection epidemic coupled with more efficacious and available treatments has led to a larger number of patients living with HIV or AIDS. As a result, skin manifestations related to HIV/AIDS or its therapy have become increasingly more common and are reported to occur in as many as 95% of patients. Herein, we review the most common HIV/AIDS related cutaneous pathologies and classify them into inflammatory, HAART-associated, neoplastic, and infectious manifestations. Read More

    Reprogramming of myeloid angiogenic cells by Bartonella henselae leads to microenvironmental regulation of pathological angiogenesis.
    Cell Microbiol 2015 Oct 19;17(10):1447-63. Epub 2015 May 19.
    Institute for Medical Microbiology and Infection Control, Goethe University, Frankfurt am Main, Germany.
    The contribution of myeloid cells to tumour microenvironments is a decisive factor in cancer progression. Tumour-associated macrophages (TAMs) mediate tumour invasion and angiogenesis through matrix remodelling, immune modulation and release of pro-angiogenic cytokines. 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.

    Infection with Bartonella henselae in a Danish family.
    J Clin Microbiol 2015 May 4;53(5):1556-61. Epub 2015 Mar 4.
    Intracellular Pathogens Research Laboratory, Center for Comparative Medicine and Translational Research, College of Veterinary Medicine, North Carolina State University, Raleigh, North Carolina, USA
    Bartonella species constitute emerging, vector-borne, intravascular pathogens that produce long-lasting bacteremia in reservoir-adapted (natural host or passive carrier of a microorganism) and opportunistic hosts. With the advent of more sensitive and specific diagnostic tests, there is evolving microbiological evidence supporting concurrent infection with one or more Bartonella spp. in more than one family member; however, the mode(s) of transmission to or among family members remains unclear.
