Fulminant herpes simplex virus hepatic failure in pregnancy requiring liver transplantation

Donor-derived fulminant herpes simplex virus hepatitis after liver transplantation: Two cases and review of literature

BACKGROUND

Fulminant herpetic hepatitis due to herpes simplex virus (HSV), serotype 1 or 2, is a rare but often fatal complication after solid organ transplantation (SOT). HSV hepatitis in SOT recipients can occur either due to primary infection acquired post transplantation, viral reactivation in a seropositive patient, or as donor-derived infection. Cases of fatal hepatitis have been reported in the liver as well as in other SOT recipients. The fatal outcome is mostly due to delayed diagnosis and treatment, which is explained by the lack of clinical specificity of HSV hepatitis.

METHODS

We report two cases of fatal donor-derived HSV hepatitis in liver-transplanted recipients. We reviewed all published cases of donor-derived HSV infections after SOT with an evaluation of the presence of prophylaxis and outcome.

RESULTS

In both liver recipients, the retrospective determination of HSV serostatus was negative, and both cases occurred in the absence of cytomegalovirus or HSV prophylaxis. A review of the literature showed a significant series of cases of severe hepatitis, mostly fatal, as well as the absence of specific preventive therapy guidelines in cases of HSV serology mismatch.

CONCLUSIONS

The occurrence of two fatal donor-derived hepatitis made the Swiss Transplant Infectious Diseases working group modify its national recommendations regarding pretransplant serostatus determination and HSV prophylaxis after liver transplantation. Further studies are needed to assess this approach.

Urgent Liver Transplantation for Acute Liver Failure in Pregnant Women: The Optimum Timing for Delivery

BACKGROUND

The occurrence of acute liver failure (ALF) in pregnant women due to an etiology unrelated to pregnancy (pregALF) that leads to liver transplantation (LT) has rarely been reported. The objective was to report the outcome of pregnant women and fetus and propose a strategy for the timing of delivery and of LT in these patients.

METHODS

Five consecutive pregnant patients with ALF were admitted to our center between 1986 and 2018 and underwent an LT. A systematic review of case reports concerning patients with pregALF who underwent LT was extracted from the literature.

RESULTS

Three with gestational ages (GA) at admission of 15, 22, and 31 weeks of gestation (WG) were transplanted after delivery (n = 1) or intrauterine demise (n = 2) and 2 with GA of 16 and 23 WG before delivery. One infant survived in each group. Among the 32 cases published previously, 11 (34%) had been transplanted after delivery (median GA:31 [28-33]); 10 of these 11 infants were alive at birth. The other 21 mothers were transplanted before delivery (GA:21 WG [18-22]). The median GA at delivery was 30 WG [27.75-37]. Twelve of 21 infants were alive at birth. One-year survival among the ALF patients in our series and in the literature was 100%. Overall, the perinatal survival rate was low (64.8%).

CONCLUSIONS

In pregnant patients presenting with ALF not related to the pregnancy, the LT lifesaving procedure had an excellent outcome. Overall, 65% of the infants were alive at delivery with major mortality in those fetus <22 WG despite continued pregnancy.

A literature review of herpes simplex virus hepatitis in pregnancy

Purpose: Hepatitis due to herpes simplex virus (HSV) during pregnancy is rare, it is often not included in the differential disease. However, hepatitis leads to maternal death; hence, early diagnosis is necessary. Hepatic enzyme elevation in late pregnancy is often associated with obstetric-related diseases, such as acute gestational fatty liver and HELLP syndrome (hemolytic anemia, elevated liver enzymes, low platelet count). These pregnancy-related diseases often improve maternal condition after completion of pregnancy, but in patients with HSV hepatitis, invasive treatment, such as cesarean section, may lead to deterioration of maternal condition after completion of pregnancy. A systematic review was conducted to extract necessary factors to avoid maternal death caused by herpetic hepatitis.Methods: In 24 cases reported since 1991, age, onset gestational weeks, initial symptoms, days from onset of symptoms to consultation, diagnosis method, treatment method, maximum liver escape enzyme value during hospitalization, bilirubin value, international normalized ratio value, and fetal/neonatal prognosis were extracted, and the relationship between maternal death group (n = 6) and maternal alive group (n = 18) was statistically analyzed.Results: Fever as an initial symptom was observed in all cases. Maternal death did not occur in patients administered with acyclovir (ACV) as empiric therapy. No difference was found between the two groups in other factors.Conclusion: Early diagnosis and treatment of herpetic hepatitis during pregnancy are important, as well as administration of empiric ACV concurrently with noninvasive diagnosis when a pregnant woman has elevated liver enzyme accompanied by fever in late pregnancy.

[Genital herpes and pregnancy: Epidemiology, clinical manifestations, prevention and screening. Guidelines for clinical practice from the French College of Gynecologists and Obstetrician (CNGOF)]

OBJECTIVES

To analyze the consequences of genital herpes infections in pregnant women.

METHODS

The PubMed database and the recommendations from the French and foreign obstetrical societies or colleges have been consulted.

RESULTS

The symptomatology of herpes genital rash is often atypical (NP2) and not different during pregnancy (Professional consensus). It is most often due to HSV2 (NP2). Seventy percent of pregnant patients have a history of infection with Herpes simplex virus, without reference to genital or labial localization, and this is in most cases type 1 (NP2). The prevalence of clinical herpes lesions at birth in the event of recurrence is about 16% compared with 36% in the case of initial infection (NP4). In HSV+ patients, asymptomatic herpetic excretion is 4 to 10%. The rate of excretion increases in HIV+ patients (20 to 30%) (NP2). The risk of HSV seroconversion during pregnancy is 1 to 5% (NP2), but can reach 20% in case of sero-discordant couple (NP2). Questioning is not always sufficient to determine the history of herpes infection of a patient and her partner (NP2) and the clinical examination is not always reliable (NP2). Herpetic hepatitis and encephalitis are rare and potentially severe (NP4). These diagnoses should be discussed during pregnancy and antiviral therapy should be started as soon as possible (Professional consensus). There is no established link between herpes infection and miscarriages (NP3). There appears to be an association between untreated herpes infection and premature delivery (NP3) but not in the case of treated infections (NP4). Herpetic fetopathies are exceptional (NP4). There is no argument for recommending specific prenatal diagnosis for herpes infection during pregnancy (Professional consensus). Condom use reduces the risk of initial infection in women who are not pregnant (NP3). There is no evidence to justify routine screening during pregnancy (Professional consensus).

CONCLUSION

There is a strong discrepancy between the prevalence of herpetic excretion at the time of delivery and the scarcity of neonatal infections. There is a lack of data on the impact of herpes infections during pregnancy in France. Fetal and maternal consequences are potentially serious but rare.

A fatal case of herpes simplex virus hepatitis in a pregnant patient

We present a middle aged pregnant woman who developed signs and symptoms of acute liver failure and was found to have herpes simplex virus hepatitis. Patient had an emergent delivery and was started on antiviral therapy, but unfortunately due to the severity of her liver failure, she passed away. The importance of reporting this case is to emphasize on the importance of considering herpes simplex infection in pregnant women who present with acute liver failure, and the importance of early administration of antiviral therapy.

Disseminated herpes simplex infection during pregnancy, rare but important to recognise

Disseminated herpes simplex virus (HSV) infection during pregnancy is a rare, but potentially fatal condition. We present a case where prompt treatment with intravenous acyclovir resulted in a successful outcome for both mother and baby.

Antiviral-resistant fulminant herpes hepatitis in pregnancy

Fulminant herpes hepatitis with disseminated extrahepatic involvement in pregnancy is rare and carries a high mortality risk. Although acyclovir remains standard first-line therapy, effective management of acyclovir-resistant disseminated herpes simplex virus (HSV) in pregnancy remains elusive. We present a case of disseminated HSV resistant to both acyclovir and foscarnet, the first double-agent resistant case in pregnancy reported in the literature to date. In this case, therapeutic delivery was the ultimate treatment resulting in full recovery.

Pregnancy-Associated Kidney Injury

A 23-year-old G1P0000 without prior past medical history is 31 weeks pregnant with prenatal care presents with complaints of worsening leg and face swelling for the past 2 days now seeks care because of headache, diarrhea, nausea, and vomiting. On exam she is found to have a blood pressure of 120/86, edema, and brisk deep tendon reflexes. Laboratory testing revealed hemoglobin 11.3 g/dl, platelet count 141,000/μl white blood count 18,000/μl, creatinine 1.1 mg/dl, aspartate aminotransferases (AST) 65 U/l, lactate dehydrogenase (LDH) 400 U/l, total bilirubin 1.1 mg/dl, prothrombin time (PT) 14.7 s, ammonia of 90 mcg/dl, blood glucose 139 mg/dl, calcium 7.3 mg/dl, and uric acid of 6.0 mg/dl. The urinalysis demonstrated WBC’s 3–5/hpf, RBC’s 3–5/hpf—non-dysmorphic, renal tubular epithelial cells were seen and a urine protein to creatinine ratio of 2. One day after hospitalization the patient’s blood pressure was 145/87 with a similar blood pressure 6 h later.
