Fulminant Hepatic Failure due to Varicella Zoster in a Heart Transplant Patient: Successful Liver Transplant

Fatal Hyperacute Liver Failure due to Varicella Zoster Virus Immediately After Living-Donor Liver Transplantation: A Case Report and Review of the Literature

BACKGROUND

Although acute hepatitis caused by varicella zoster virus mostly develops in immunocompromised patients, hyperacute liver failure is very rare. To our knowledge, there are no previous reports on liver transplant patients.

METHODS

We report the first case of fatal hyperacute liver failure due to varicella zoster virus immediately after living-donor liver transplantation without cutaneous lesions and review the literature.

RESULT

The present case exhibited rapid development and progression of acute liver failure from postoperative days 11-13, despite being seropositive for varicella zoster virus but unvaccinated and on immunosuppression before transplantation. Especially in solid organ transplantation, only six cases of severe acute liver failure that included hepatic encephalopathy and/or impaired consciousness and sudden extremely high (> 4000 U/L) serum aspartate aminotransferase levels have been reported in heart, lung, and kidney transplant patients.

CONCLUSIONS

Early diagnosis of hyperacute liver failure due to varicella zoster virus is challenging because the disease progresses rapidly and skin lesions are absent.

Viral etiologies of acute liver failure

Acute liver failure (ALF) is a rare cause of liver-related mortality worldwide, with an estimated annual global incidence of more than one million cases. While drug-induced liver injury, including acetaminophen toxicity, is the leading cause of ALF in the Western world, viral infections remain a significant cause of ALF and the most common cause in many developing nations. Given the high mortality rates associated with ALF, healthcare providers should be aware of the broad range of viral infections that have been implicated to enable early diagnosis, rapid treatment initiation when possible, and optimal management, which may include liver transplantation. This review aims to provide a summary of viral causes of ALF, diagnostic approaches, treatment options, and expected outcomes.

Fulminant varicella hepatitis: a rare but lethal cause of abdominal pain

An 81-year-old woman with no history of immunocompromise presented with 2 days of upper abdominal pain associated with nausea. On arrival, her physical examination was unremarkable apart from mild epigastric and right hypochondriac tenderness, and laboratory investigations were unremarkable apart from mild thrombocytopenia and transaminitis. A CT scan performed on the day of admission revealed a tiny 0.3 cm stone in the common bile duct, with no upstream dilatation. On day 2 of admission, she developed a vesicular rash and with acutely worsening transaminitis. She deteriorated rapidly and demised from complications of acute liver failure within the next 24 hours. The diagnosis of varicella was confirmed with antibody testing. Fulminant varicella hepatitis is an extremely rare and lethal condition with only a handful of reported cases in the current literature. We aim to share our clinical experience and summarise the salient points from existing case reports.

Rare presentation of primary varicella zoster as fatal fulminant hepatitis in adult on low-dose,short-term steroid: Case report

Background

Varicella zoster virus presents clinically as primary (chickenpox) or secondary (herpes zoster) infection. Cutaneous and extracutaneous dissemination may occur, usually in immunocompromised patients. VZV hepatitis that progresses to fulminant hepatic failure is very rare and fatal. To the best of our knowledge, 9 cases have been reported to date, of which 7 were in immunocompromised adults, and only one patient was on short duration steroid therapy.

Presentation of case

We present a 26-year old man who was admitted initially with acute abdomen as query persistent biliary colic. Later, he showed clinical and laboratory findings of VZV hepatitis that progressed rapidly despite maximal medical ICU support and he expired on day 3 of admission.

Conclusions

Acute VZV infection may present as fulminant hepatitis. The presentation may initially be challenging for the diagnosis and should be considered if the patient has been in contact with a sick case. Low dose corticosteroid could carry a risk for fatal VZV fulminant hepatitis and should be used very cautiously especially with VZV patients' contacts. Further causative relationships remain to be established.

Varicella zoster virus in solid organ transplantation: Guidelines from the American Society of Transplantation Infectious Diseases Community of Practice

These updated guidelines from the American Society of Transplantation Infectious Diseases Community of Practice review the diagnosis, prevention, and management of varicella zoster virus (VZV) in the pre- and post-transplant period. Primary varicella is an uncommon complication post-solid-organ transplant (SOT), except among pediatric transplant patients and those seronegative for VZV. As the majority of SOT recipients are seropositive for VZV, herpes zoster (HZ) occurs frequently following SOT, particularly among recipients who are older (≥65 years of age) and those receiving more intensive immunosuppression. Transplant providers should aware of the increased risk for HZ-related complications such as dissemination, organ-specific involvement, and post-herpetic neuralgia. Treatment for localized zoster is primarily given as oral regimens, but those with more complicated presentations or those at risk for dissemination should be treated initially with IV therapy. Available antiviral prophylaxis regimens and vaccination strategies for varicella and HZ among these immunosuppressed patients remain a mainstay for prevention in the pre-and post-transplant periods. Finally, we discuss important approaches to addressing post-exposure prophylaxis and infection control practices for those SOT patients with documented VZV infections.

Varicella-Zoster Virus-Induced Hepatitis in a Liver Transplant Recipient: A Case Report

Infections after solid organ transplantation are a major cause of mortality and morbidity. Varicella-zoster virus (VZV) infection after solid organ transplantation is rare. Here we present a case presenting with acute hepatitis and shingles after a liver transplantation (LT). A 36-year-old male patient underwent a liver transplantation; 7 months later his liver function tests increased. An examination and test results revealed that he had VZV-induced hepatitis. After VZV treatment, his test results returned to normal levels. Hepatic involvement of VZV infection is rare, but it may be fatal in immunocompromised individuals. Early diagnosis and early initiation of antiviral therapy is important in the control of hepatitis and rare hepatotropic viruses in immunocompromised individuals.

Acute Liver Failure due to Disseminated Varicella Zoster Infection

Acute liver failure (ALF) can be due to numerous causes and result in fatality or necessitate liver transplantation if left untreated. Possible etiologies of ALF include ischemia, venous obstruction, medications, toxins, autoimmune hepatitis, metabolic and infectious causes including hepatitis A-E, varicella-zoster virus (VZV), cytomegalovirus (CMV), herpes simplex virus (HSV), Epstein-Barr virus (EBV), and adenovirus with VZV being the most rarely reported. Pathognomonic skin lesions facilitate diagnosis of VZV hepatitis, but definitive diagnosis is secured with liver biopsy, tissue histopathology, culture, and specific VZV polymerase chain reaction (PCR). Antiviral treatment with intravenous acyclovir can be effective if initiated in a timely manner; however, comorbidities and complications frequently result in high mortality, especially in immunocompromised hosts as exemplified in this case presentation.

Varicella with rapidly progressive hepatitis presenting with multiple hepatic nodules in a child with acute leukemia

Abdominal pain may precede the characteristic varicella skin lesions in immunocompromised patients with visceral varicella. The absence of skin lesions may delay timely diagnosis and treatment of varicella for those patients. Furthermore, abdominal imaging findings to provide information to diagnose visceral varicella have rarely been reported. Varicella was diagnosed in a 5-year-old boy with acute lymphoblastic leukemia complaining of fever and abdominal pain followed by papulovesicular skin lesions. Later, the patient was found to have rapidly progressive acute hepatitis, and abdominal computed tomography showed multiple hypodense hepatic nodules. The patient was treated with intravenous acyclovir, intravenous immunoglobulin, and empirical antibiotic and antifungal therapy. However, his fever and abdominal pain persisted, and a laparoscopic liver biopsy was performed to differentiate other causes of the persisting symptoms. Eventually, the patient was diagnosed with visceral varicella based on histopathologic findings. In conclusion, visceral varicella should be considered in immunocompromised patients with abdominal pain and multiple hypodense hepatic nodules on abdominal imaging studies. However, bacteria, fungi, and tuberculosis can produce similar imaging findings; therefore, a biopsy may be necessary in patients not responding to antiviral therapy.

Successful rescue of disseminated varicella infection with multiple organ failure in a pediatric living donor liver transplant recipient: a case report and literature review

A 12-year-old female patient with biliary atresia underwent living donor liver transplantation (LDLT). Twelve months after the LDLT, she developed acute hepatitis (alanine aminotransferase 584 IU/L) and was diagnosed with disseminated varicella-zoster virus (VZV) infection with high level of serum VZV-DNA (1.5 × 10⁵ copies/mL) and generalized vesicular rash. She had received the VZV vaccination when she was 5-years-old and had not been exposed to chicken pox before the LDLT, and her serum was positive for VZV immunoglobulin G at the time of the LDLT. Although she underwent treatment with intravenous acyclovir, intravenous immunoglobulin, and withdrawal of immunosuppressants, her symptoms worsened and were accompanied by disseminated intravascular coagulation, pneumonia, and encephalitis. These complications required treatment in the intensive care unit for 16 days. Five weeks later, her clinical findings improved, although her VZV-DNA levels remained high (8.5 × 10³copies/mL). Oral acyclovir was added for 2 weeks, and she was eventually discharged from our hospital on day 86 after admission; she has not experienced a recurrence. In conclusion, although disseminated VZV infection with multiple organ failure after pediatric LDLT is a life-threatening disease, it can be cured via an early diagnosis and intensive treatment.

Acute liver failure due to Varicella zoster virus infection after lung transplantation: a case report

Most adults are Varicella zoster virus (VZV)-positive at the age of 20 years. Some, however, remain antibody-negative and may develop primary chicken pox during adulthood. We report a patient with Williams-Campbell syndrome who underwent double-lung transplantation while being VZV-negative. One year after the successful procedure, he was admitted with fulminant hepatic failure and some cutaneous vesicles in his face. Despite a rapid diagnosis of VZV infection and treatment with acyclovir, his situation deteriorated within 24 hours and while awaiting an urgent liver transplantation, he developed multiple organ failure and died.
