Abstract
Herpes simplex virus (HSV) is a rare cause of acute hepatitis in patients with chronic immunosuppression, including Crohn's disease. HSV hepatitis has the propensity to cause acute liver failure and death. The presenting signs and symptoms can be nonspecific, thereby causing the diagnosis to go overlooked with inadequate management, leading to a high mortality rate. We report a case of a 31-year-old male on chronic prednisone treatment for Crohn's disease who unexpectedly died. Subsequently, an autopsy showed HSV hepatitis as the cause of death. Thus, although a rare complication, HSV hepatitis should always be kept in mind as a fatal complication in patients with acute hepatitis and chronic immunosuppression.

Abstract
Herpes simplex virus (HSV) hepatitis represents a rare complication of HSV infection, which can progress to acute liver failure and, in some cases, death. We describe an immunocompetent 67-year-old male who presented with one week of fever and abdominal pain. Computed tomography (CT) scan and magnetic resonance imaging (MRI) of the abdomen showed multiple bilobar hepatic lesions, some with rim enhancement, compatible with liver abscesses. Subsequent liver biopsy, however, revealed hepatocellular necrosis, HSV-type intranuclear inclusions, and immunostaining positive for herpes virus type 2 (HSV-2). Though initially treated with broad-spectrum antibiotics, following histologic diagnosis of HSV hepatitis, the patient was transitioned to intravenous acyclovir for four weeks and he achieved full clinical recovery. Given its high mortality and nonspecific presentation, one should consider HSV hepatitis in all patients with acute hepatitis with multifocal hepatic lesions of unknown etiology. Of special note, this is only the second reported case of HSV liver lesions mimicking pyogenic abscesses on CT and MRI.

Abstract
HSV hepatitis is a rare but often fatal cause of liver failure which tends to affect immunocompromised individuals. Early treatment with Acyclovir has been shown to reduce mortality in HSV hepatitis making recognition of the condition critically important. Here, we present a case of HSV hepatitis in a young woman with Crohn's disease on Prednisone, Azathioprine, and Infliximab. We discuss the clinical presentation of HSV hepatitis as well as the possible causes of hepatitis in a patient on these medications. This case helps demonstrate the importance of early clinical suspicion for HSV in undifferentiated fulminate liver failure. It is also the first reported case of HSV hepatitis in a patient on Infliximab, raising the possibility of HSV reactivation in patients on Infliximab.

Abstract
Liver enzymes, including aminotransferases and alkaline phosphatase, are some of the most commonly ordered blood tests in a physician's practice. These enzymes have been valuable in screening for liver disease, as well as in diagnosing and monitoring patients with acute and chronic hepatobiliary disorders. Patients with predominantly aminotransferase elevations are thought to have acute or chronic hepatitis from a variety of causes. In patients with predominantly alkaline phosphatase elevations, imaging evaluation is undertaken upfront to exclude large bile duct disorders and infiltrative/mass lesions. A liver biopsy may be reserved for patients for whom these less invasive investigations are unfruitful.

Abstract
Objective. To present a case of a healthy 41-year-old female who developed fulminant hepatic failure leading to death. The cause of hepatic failure identified on postmortem exam was herpes simplex virus hepatitis. Design. Observation of a single patient. Setting. Intensive care unit of a tertiary care university teaching hospital in Canada. Patient. 41-year-old previously healthy female presenting with a nonspecific viral illness and systemic inflammatory response syndrome. Intervention. The patient was treated with intravenous fluids and broad-spectrum antibiotics. On the second day of admission, she was found to have elevated transaminases, and, over 48 hours, she progressed to fulminant liver failure with disseminated intravascular coagulopathy, refractory lactic acidosis, and shock. She progressed to respiratory failure requiring intubation and mechanical ventilation. She was started on N-acetylcysteine, a bicarbonate infusion, hemodialysis, and multiple vasopressors and inotropes. Measurements and Main Results. Despite treatment, the patient died roughly 70 hours after her initial presentation to hospital. Her postmortem liver biopsy revealed herpes simplex virus hepatitis as her cause of death. Conclusions. Herpes simplex virus must be considered in all patients presenting with liver failure of unknown cause. If suspected, prompt treatment with acyclovir should be initiated.

Abstract
Introduction We present the case of a 49-year-old woman with a seronegative rheumatoid arthritis who developed pustular psoriasis whilst on etanercept and subsequently developed disseminated herpes simplex on infliximab. Case presentation Our patient presented with an inflammatory arthritis which failed to respond to both methotrexate and leflunomide, and sulphasalazine treatment led to side effects. She was started on etanercept but after 8 months of treatment developed scaly pustular lesions on her palms and soles typical of pustular psoriasis. Following the discontinuation of etanercept, our patient required high doses of oral prednisolone to control her inflammatory arthritis. A second biologic agent, infliximab, was introduced in addition to low-dose methotrexate and 15 mg of oral prednisolone. However, after just 3 infusions of infliximab, she was admitted to hospital with a fever, widespread itchy vesicular rash and worsening inflammatory arthritis. Fluid from skin vesicles examined by polymerase chain reaction showed Herpes Simplex Virus type 1. Blood cultures were negative and her chest X-ray was normal. Her infliximab was discontinued and she was started on acyclovir, 800 mg five times daily for 2 weeks. She made a good recovery with improvement in her skin within 48 hours. She continued for 2 months on a prophylactic dose of 400 mg bd. Her rheumatoid arthritis became increasingly active and a decision was made to introduce adalimumab alongside acyclovir. Acyclovir prophylaxis has been continued but the dose tapered so that she is taking only 200 mg of acyclovir on alternate days. There has been no recurrence of Herpes Simplex Virus lesions despite increasing adalimumab to 40 mg weekly 3 months after starting treatment. Conclusion We believe this to be the first reported case of widespread cutaneous Herpes Simplex Virus type 1 infection following treatment with infliximab. We discuss the clinical manifestations of Herpes Simplex Virus infections with particular emphasis on the immunosuppressed patient and the use of prophylactic acyclovir. Pustular psoriasis is now a well recognised but uncommon side effect of antitumour necrosis factor therapy and can lead to cessation of therapy, as in our patient's case.

Abstract
Hepatitis is a rare complication of herpes simplex virus (HSV), often leading to acute liver failure (ALF), liver transplantation (LT), and/or death. Our aim was to identify variables associated with either survival or progression (death/LT), based on an analysis of cases in the literature and our institution. A total of 137 cases (132 literature, 5 institutional) of HSV hepatitis were identified. The main features at clinical presentation were fever (98%), coagulopathy (84%), and encephalopathy (80%). Rash was seen in less than half of patients. Most cases (58%) were first diagnosed at autopsy and the diagnosis was suspected clinically prior to tissue confirmation in only 23%. Overall, 74% of cases progressed to death or LT, with 51% in acyclovir-treated patients as compared to 88% in the untreated subjects (P=0.03). Variables on presentation associated with death or need for LT compared to spontaneous survival: male gender, age>40 yr, immunocompromised state, ALT>5,000 U/L, platelet count<75x10(3)/L, coagulopathy, encephalopathy, and absence of antiviral therapy. In conclusion, HSV hepatitis has a high mortality and is often clinically unsuspected. Patients who are male, older, immunocompromised, and/or presenting with significant liver dysfunction are more likely to progress to death and should thus be evaluated for LT early. Based on the frequent delay in HSV diagnosis, low risk-benefit ratio, and significantly improved outcomes, empiric acyclovir therapy for patients presenting with ALF of unknown etiology is recommended until HSV hepatitis is excluded.

Abstract
BACKGROUND Herpes simplex virus hepatitis is a rare complication associated with a poor prognosis and a high mortality rate. It mainly affects adults with impaired cell-mediated immunity. Mucocutaneous involvement is seen in only 57% to 70% of patients and the clinical aspects of the lesions may sometimes be misleading. Here we report a new case that developed during primary HSV-2 infection in a patient with systemic lupus erythematosus. CASE REPORT A 57 year-old man with systemic lupus erythematosus treated with oral prednisone presented a disseminated varicella-like eruption with acute liver failure related to primary genital HSV-2 infection. Type-specific HSV deoxyribonucleic acid amplification by polymerase chain reaction on serum and oral lesion samples revealed type 2 HSV. Dramatic improvement was observed with parenteral acyclovir. DISCUSSION Hepatitis due to HSV is a rare but potentially fatal disorder chiefly affecting adults with impaired immune systems. In this case, HSV affects the liver during primary or recurrent infection. If initiated quickly, parenteral acyclovir can cure hepatitis, which means that this diagnosis must be considered in both immunocompromised and immunocompetent patients with high fever, leucopoenia and marked elevation of aminotransferase levels. Mucocutaneous signs are present in only 57 to 70% of cases. Careful physical examination to detect herpes lesions should be done in all cases of acute liver failure. HSV viremia testing may confirm the diagnosis by non-invasive means. Patients with systemic lupus erythematosus are at increased risk for infection due to immunosuppressive drugs, but also to numerous intrinsic immunologic abnormalities such as a recently reported deficit in NK cells and plasmacytoid dendritic cells.

Abstract
In immunocompetent patients, primary infection by herpes simplex virus (HSV), varicella-zoster virus (VZV), cytomegalovirus (CMV), human herpesvirus 6, and Epstein-Barr virus (EBV) generally produces mild, self-limited hepatitis. Primary infection by HSV in neonates and pregnant women, and infection by VZV in hematological and bone marrow recipients can cause fulminant hepatitis without characteristic skin lesions. In liver transplant recipients, hepatitis is the most common expression of CMV infection and the related symptoms are indistinguishable from those of acute rejection. Persistent hepatitis is a manifestation of the syndrome of active chronic infection by the EBV. Fulminating hepatitis due to herpes virus can be treated effectively if therapy is started early; hence, a high degree of clinical suspicion and inclusion of herpes virus in the differential diagnosis of this syndrome is necessary.

Abstract
We report on a case of herpes simplex virus (HSV) type 1 colitis in a 69-year-old patient with common variable immunodeficiency syndrome. A treatment with polyvalent immunoglobulins was discontinued in April 2001. In March 2004 she developed chronic diarrhoea related to rectosigmoidal and caecal ulcerations. In November 2004, HSV was recovered in tissue culture from colonic biopsies. Valaciclovir was then started, leading the patient to clinical remission at day 4, and continued for a 6-week course (without any secondary antiviral prophylaxis). Colonic biopsies were negative for HSV by tissue culture and PCR within 3 weeks of antiviral treatment. Intravenous polyvalent immunoglobulin infusions were readministered within the third week of antiviral treatment. She has declared no clinical event since this period. Three months after the antiviral treatment was achieved, a rectosigmoidoscopy showed an ad-integrum macroscopic and histological mucosal healing whereas PCR was negative for HSV in the colonic tissue. As a large proportion of patients with common variable immunodeficiency syndrome present not only as a humoral immunodeficiency but also as a defect in the cellular immunity compartment (with T-cell deficits), HSV, as well as cytomegalovirus, should be investigated in patients with common variable immunodeficiency syndrome presenting colitis.

Abstract
Acute liver failure (ALF) is an uncommon medical emergency whose rapid progression and high mortality demand early diagnosis and expert management, including immediate transfer of any potential case to facilities for intensive care and orthotopic liver transplantation (OLT). All patients with ALF must be screened aggressively for acetaminophen toxicity (history, serum levels, "hyperacute" presentation with renal failure), for other drugs, and viral hepatitis; rare causes of ALF should also be considered. After an acetaminophen overdose, N-acetylcysteine must be given as early as possible, preferably in the emergency room, but any patient with ALF should promptly receive N-acetylcysteine if there is suspicion of acetaminophen toxicity irrespective of the time of ingestion. Supportive care for all patients with ALF includes adequate enteral nutrition, aggressive screening and treatment of infection, prophylactic broad-spectrum antibiotics, and antifungal agents. Sedation with propofol is given for severe agitation or mechanical ventilation. With advanced coma grades, intensive care is needed with hemodynamic monitoring, ventilatory support, continuous renal replacement for renal failure, and intracranial pressure monitoring. Intracranial hypertension is treated with mannitol and/or acute short-term hyperventilation, but if the patient is refractory to treatment, mild-moderate hypothermia is achieved by a cooling blanket that is continued throughout OLT. Barbiturate coma is only used in refractory cases as the last treatment modality. Seizures are aggressively treated with phenytoin, with additional diazepam as needed. Candidacy and activation for OLT should be completed as early as possible in the course of ALF, especially in "hyperacute" cases such as acetaminophen toxicity. The final decision to proceed with OLT is made when a donor organ becomes available. King's College Hospital criteria for OLT are still the best prognostic assessment for fatal outcome in ALF, but the criteria fail to identify some patients who will die.
