    Rejection, Recurrence, or Something Else?
    Bol Asoc Med P R 2016 ;108(2):39-41
    Since the introduction of liver transplant as treatment for end-stage liver disease, thousands of lives have been saved. To prevent organ rejection, immunosuppression is given chronically and hence, patients are at increased risk for opportunistic infections related to immunosuppression, especially within the first year after the transplant. However, opportunistic infections can occur years after the transplantation. Read More

    Epidermal Growth Factor Receptor Expression Licenses Type-2 Helper T Cells to Function in a T Cell Receptor-Independent Fashion.
    Immunity 2017 Oct;47(4):710-722.e6
    Institute of Immunology and Infection Research, University of Edinburgh, EH9 3FL Edinburgh, UK. Electronic address:
    Gastro-intestinal helminth infections trigger the release of interleukin-33 (IL-33), which induces type-2 helper T cells (Th2 cells) at the site of infection to produce IL-13, thereby contributing to host resistance in a T cell receptor (TCR)-independent manner. Here, we show that, as a prerequisite for IL-33-induced IL-13 secretion, Th2 cells required the expression of the epidermal growth factor receptor (EGFR) and of its ligand, amphiregulin, for the formation of a signaling complex between T1/ST2 (the IL-33R) and EGFR. This shared signaling complex allowed IL-33 to induce the EGFR-mediated activation of the MAP-kinase signaling pathway and consequently the expression of IL-13. Read More

    Electromagnetic fields may act via calcineurin inhibition to suppress immunity, thereby increasing risk for opportunistic infection: Conceivable mechanisms of action.
    Med Hypotheses 2017 Sep 3;106:71-87. Epub 2017 Jul 3.
    The Experimental Dermatology Unit, Department of Neuroscience, Karolinska Institute, 171 77 Stockholm, Sweden. Electronic address:
    While a good number of studies have demonstrated that modern, man-made ambient electromagnetic fields can have both stimulatory and inhibitory effect on immune system function, the precise mechanisms have yet to be completely elucidated. It is hypothesized here that, depending on the parameters, one of the means by which long-term electromagnetic field exposure has the potential to eventually lead to immunosuppression is via downstream inhibition of the enzyme calcineurin - a protein phosphatase, which activates the T-cells of the immune system and can be blocked by pharmaceutical agents. Calcineurin is the target of a class of pharmaceuticals called calcineurin inhibitors (e. Read More

    Imaging Spectrum of Invasive Fungal and Fungal-like Infections.
    Radiographics 2017 Jul-Aug;37(4):1119-1134. Epub 2017 Jun 16.
    From the Mallinckrodt Institute of Radiology, Washington University School of Medicine, 510 S Kingshighway Blvd, Box 8131, St Louis, MO 63110 (H.L.P.O., S.M., V.M.M., S.B.); Department of Radiology, University of Wisconsin, Madison, Wis (M.G.L., P.J.P.); and Department of Radiology, Mayo Clinic, Scottsdale, Ariz (C.O.M.).
    Invasive fungal and fungal-like infections contribute to substantial morbidity and mortality in immunocompromised individuals. The incidence of these infections is increasing-largely because of rising numbers of immunocompromised patients, including those with neutropenia, human immunodeficiency virus, chronic immunosuppression, indwelling prostheses, burns, and diabetes mellitus, and those taking broad-spectrum antibiotics. Invasive fungal pathogens include primary mycotic organisms such as Histoplasma capsulatum, Coccidioides immitis, Blastomyces dermatitidis, and Paracoccidioides brasiliensis, which are true pathogens and inherently virulent.

    Anti-TNFα agents have proved effective in the treatment of various inflammatory, rheumatologic, dermatologic, and gastrointestinal diseases. Severe respiratory tract infections of bacterial or fungal origin have emerged as important complications in patients receiving such treatments. The risk of infection due to anti-TNFα therapy is difficult to assess in these patients who are immunocompromised because of the underlying disease itself and of previous or concomitant immunosuppressive drugs.

    Practical Management of Deep Cutaneous Fungal Infections.
    Med Mycol J 2017 ;58(2):E71-E77
    Department of Dermatology, Kitasato University Kitasato Institute Hospital.
    Understanding deep cutaneous fungal infection requires not only reading many case reports and checking the typical clinical images of skin lesions, but also managing the patients properly to prevent misdiagnosis. Herein, I review my recent experiences with eight typical cases of deep cutaneous infections (including protothecosis and nocardiosis) in Japan. It is very important to do the four management processes; namely, KOH direct microscopic examination, skin biopsy, fungal culture, and microscopic examination of the histopathological specimen of PAS and Grocott staining.
