Purpose Of Review: Clinicians started to notice the cases of an outbreak of acute hepatitis C (AHC) infections among HIV-positive MSM in Europe almost 10 years ago. Similar reports from the USA and Australia soon followed. In the absence of randomized controlled treatment trials clinicians have to rely on published data from uncontrolled clinical and cohort studies to develop treatment algorithms in these patients and give recommendations on best clinical management.
Recent Findings: Data from recent cohort studies indicate that the early course of hepatitis C virus (HCV) RNA in the first 4 weeks after diagnosis may be a helpful predictor of spontaneous clearance of AHC in HIV-infected individuals. Additionally, single-nucleotide polymorphisms near the IL28B gene have been demonstrated to impact chances of spontaneous clearance. Pegylated interferon in combination with weight-adapted ribavirin is recommended as treatment of choice for all HCV genotypes. For patients developing a rapid virological response, defined as a negative HCV-RNA in an ultrasensitive assay, treatment duration of 24 weeks is recommended. Overall, high-sustained virological response rates of 60-80% have been observed if antiviral therapy was initiated within 24 weeks after diagnosis.
Summary: The current epidemic of AHC particularly among MSM is still ongoing, and prevention and screening efforts have to be intensified to allow for control of viral dissemination. Concise recommendations for best clinical management of AHC in HIV infection have been developed on the basis of published observational data.

Although granulomatous interstitial nephritis (GIN) is a rare histological finding in kidney transplants, the joint occurrence of GIN and focal segmental glomerulosclerosis (FSGS) has not, to our knowledge, been reported in the literature. We report a case of GIN and de novo FSGS in kidney transplant recipients leading to allograft failure. A 69-year-old male with a history of end-stage renal disease (ESRD) of unknown etiology, as well as liver failure from hepatitis B and C co-infection, initially had a living unrelated kidney transplant (LURT) in 2007 and subsequently received both liver and kidney transplants (SLKTs) in 2017.

Introduction: Guillain-Barré syndrome (GBS) is an inflammatory disorder of the peripheral nervous system, causing acute flaccid paralysis. There have been occasional reports linking Hepatitis A virus (HAV) to GBS. Here we aimed to evaluate the current literature on the association between GBS and HAV, exploring potential mechanisms and clinical implications.

The opioid epidemic is a significant public health challenge in North Carolina, but limited data restrict our understanding of its complexity. Examining trends and relationships among different outcomes believed to reflect opioid misuse provides an alternative perspective to understand the opioid epidemic. We use a Bayesian dynamic spatial factor model to capture the interrelated dynamics within six different county-level outcomes, such as illicit opioid overdose deaths, emergency department visits related to drug overdose, treatment counts for opioid use disorder, patients receiving prescriptions for buprenorphine, and newly diagnosed cases of acute and chronic hepatitis C virus and human immunodeficiency virus.

Nucleoside analogs (NAs), as antiviral drugs, play a significant role in clinical medicine, constituting approximately 50 % of all antiviral therapies in current use. Nucleoside inhibitors function by mimicking the structure of natural nucleosides, integrating themselves into viral genetic material during replication, and subsequently inhibiting the virus's ability to reproduce. They are used to treat a variety of viral infections, including herpes simplex, hepatitis B, and acquired immunodeficiency syndrome (AIDS).

Autoimmune hepatitis (AIH) is an enigmatic, relatively rare disease with a variable spectrum of presentation whose pathogenesis, diagnosis and management remain a major challenge. Methods. We have performed a review incorporating recent developments in basic science, epidemiology, clinical science, therapeutics, regulatory science and evaluated the challenges associated with the application of translational research and clinical trial design to a condition that is a chameleon in nature, where outcomes range from relatively benign disease through cirrhosis and acute liver failure.
