On December 30th 2019, some patients with pneumonia of unknown etiology were reported in the Program for Monitoring Emerging Diseases (ProMED), a program run by the International Society for Infectious Diseases (ISID), hypothesized to be related to subjects who had had contact with the seafood market in Wuhan, China. Chinese authorities instituted an emergency agency aimed at identifying the source of infection and potential biological pathogens. It was subsequently named by the World Committee on Virus Classification as 2019-nCoV (2019-novel coronavirus) or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A number of studies have demonstrated that 2019-nCoV and the SARS-CoV shared the same cell entry receptor named angiotensin-converting enzyme 2 (ACE2). This is expressed in human tissues, not only in the respiratory epithelia, but also in the small intestines, heart, liver, and kidneys. Here, we examine the most recent findings on the effects of SARS-CoV-2 infection on kidney diseases, mainly acute kidney injury, and the potential role of the chemokine network.

Background: Severe, recurring epistaxis is the most common symptom of hereditary hemorrhagic telangiectasias (HHT). Current treatment modalities range from noninvasive treatments that frequently fail to achieve even short-term control to surgeries and systemic therapies that carry significant risk of complications. Recently, bevacizumab, a VEGF inhibitor, has been proposed as an alternative option to alleviate epistaxis symptoms in HHT. Objective: To review the current literature regarding the use of bevacizumab for the treatment of epistaxis in patients with HHT and provide guidance on its usage for this indication. Methods: A narrative literature review was performed to analyze various methods and dosages of bevacizumab administration for the treatment of HHT-related epistaxis, along with a review of current treatment modalities and their drawbacks. Results: The current standard of care for HHT-related epistaxis consists of treatments that are largely ineffective or invasive with significant potential complications. Submucosal bevacizumab has demonstrated efficacy in reducing frequency, duration, and severity of epistaxis in those with HHT. Conclusion: Given the inadequacies and potential drawbacks of current treatments for epistaxis in HHT, there is a need for new therapeutic options. Submucosal bevacizumab has been effective with a limited risk profile in a number of studies and should now be considered as a treatment option for refractory epistaxis. Controlled studies are recommended to quantify optimal dosing, treatment schedule, and specific subpopulations that will respond best to this treatment.

Herpes Simplex Virus (HSV) hepatitis in liver transplant patients is a rarely reported infective complication of HSV with severe consequences, often leading to fulminant hepatitis if left untreated. The clinical signs are often atypical, leading to under-reporting in the literature and potential delays in treatment. Our case report describes such atypical mucocutaneous lesions in a liver transplant recipient. We highlight the need for further reports, especially those with images, in order to aid the diagnosis of HSV infection, and to allow prompt treatment to prevent complications such as HSV hepatitis.
