Acute liver failure secondary to co-infection of Hepatitis B and HIV

Abstract

Introduction and Objectives: We present the case of a man with hepatitis B and HIV coinfection diagnosed by serological studies which presented acute liver failure; the diagnostic approach, its treatment and outcome are described. Materials and Patients: Provide information on the association of hepatitis B virus and HIV. When hepatotropic viruses are identified, intentionally find the association with other factors that cause acute liver failure, including infectious agents, drugs, and coexisting diseases.Brief description of the management to be carried out in cases of acute liver failure secondary to viral infections. Results: This is a 31-year-old man who was hospitalized when presenting in his house with jaundice syndrome, abdominal pain and a drowsy state:In his important history, he presented consumption of crystal and marijuana in a time of 8 months, high-risk sexual relations without the use of condoms, multiple sexual partners (Man who has Sex with Men), had been evaluated 7 days before as probable autoimmune hepatitis due to present positive anti-smooth muscle antibodies 1:80.On admission to our unit, he presented 7 days of evolution with hyposthenia, hypodynamia, diffuse abdominal pain, being treated at the time as autoimmune hepatitis, treatment with steroids was given, later he presented an increase in the abdominal girth and was sent to our medical institution, we received the patient in stupor state with Glasgow Coma Scale 10pts, jaundiced tint in sclerae and skin, due to the aforementioned history, a panel was performed for hepatotrophic viruses and sexually transmitted diseases such as HIV and syphilis. Finding positive HBsAg, positive rapid test for HIV and positive VDRL, later in his first 24 hours of admission to our unit, he developed prolongation of coagulation times (PT 55.5, aPTT 82.8), quantification of Total Bilirubin at 21.2mg/dl, with liver enzymes. > 6 times its normal value (AST 353, ALT 195), INR 5.15, and hepatic encephalopathy, for which an acute liver failure approach was initiated, fulfilling the defining criteria to be met: BT elevation >4mg/dl, prolonged treatment times coagulation and hepatic encephalopathy (Table 1).We report the case of a patient who presented an important history to guide viral infections as the cause of the acute hepatic process; a complete viral panel was requested that included HIV, Hepatitis A, B, C and VDRL Viruses, where the Hepatitis Antigen was positive. Hepatitis B virus surface, the rapid test for HIV, as well as the VDRL. However, in the first hours of admission, defining clinical data of acute liver failure were established by presenting Prolonged coagulation times with INR >1.5, hyperbilirubinemia >5 and type A acute hepatic encephalopathy according to the Vienna classification, for which reason management began with disaccharide laxatives (lactulose), luminal-acting antibiotics (rifaximin), fluid replacement (30ml/kg) and administration of albumin (1g/kg/day), however, according to mortality and survival scores, the patient presented a high mortality (MELD Na 49pts, 90-day mortality of 66%, NACSELD 30-day mortality of 96%), according to Factor R a mixed pattern was obtained, which is associated with hepatotropic virus infection among the main causes, and The coexistence of HBV and HIV was established as the cause of acute liver failure, since it has been established that when there is a coinfection between HBV and HIV, the possibilities of acute liver failure increase to >10%, emphasizing that in cases of liver failure acute due to viral causes, other associated factors should be sought, such as coinfection with other viruses, since the incidence of cases of acute liver failure due to a single viral agent is less than 5%. It is worth mentioning that cases have been reported that establish syphilis infection as the cause of liver failure, so it could even be considered a triple coinfection. After 48 hours of admission, the patient did not present improvement; he progressed with deterioration of renal function and hepatic encephalopathy, requiring advanced management of the airway. This procedure is the one that his relatives did not accept and for this reason, no therapy could be provided. Renal replacement or management in the intensive care unit. Conclusions: This case is highly relevant since when addressing acute liver failure, causes of viral origin must be intentionally sought. Among the viral causes, the hepatitis B virus is the one that has been most associated with developing acute liver failure. It is established that up to 4% of patients with HBV will develop this entity. In this case, the patient was infected with HIV, estimating an association between both infections of 10% as causes of acute liver failure. These patients who present coinfection should urgently start management with HAART, which presents activity for HBV. However, it is estimated that Coinfected patients who progress to acute liver failure have a poor prognosis and high mortality, leading in most cases to death. Likewise, during the course of the disease, the use of steroids is not recommended for the management of patients with virus infection. hepatotropes, so they should be avoided. In this case, despite having started treatment in the first 24 hours, the patient did not improve and once they present renal failure, renal replacement therapy and management in intensive care should be provided in order to reduce mortality and allow recovery. Liver transplantation can be used as definitive treatment provided that this resource is available and when the criteria for acute liver transplantation are met, the Kings College criteria and the Clichy criteria have been established for this purpose, an 80% success rate is estimated in cases of acute liver failure undergoing transplantation.
