Long-term survival without immunosuppression in HIV-positive liver-graft recipient

Liver transplant in patients with HIV: infection risk associated with HIV and post-transplant immunosuppression

Before the introduction of highly active antiretroviral therapy, HIV-infected patients who underwent liver transplantation (LT) had poor survival, mainly because of a rapid progression to AIDS and its infectious complications during the post-LT immunosuppression phase. However, in the era of highly active antiretroviral therapy, under some specific and well-determined conditions, LT might be as safe and efficacious in HIV patients as it is in non-HIV-infected patients. End-stage liver failure as caused by hepatitis B virus, cirrhosis, and hepatotoxicity should be considered indications for LT in every transplant center. Because of the almost universal hepatitis C virus reinfection and its accelerated course post-LT, LT in hepatitis C virus-coinfected patients deserves more caution and more extended follow-up before it is accepted as a standard indication for LT in HIV-infected patients.

Review article: current status of liver transplantation in HIV-infected patients

The increases in survival of patients infected with human immunodeficiency virus is attributed to the introduction of combination human immunodeficiency virus antiviral therapy, better known as highly active anti-retroviral therapy. In fact, survival statistics have improved such that individuals often succumb to other disease entities, notably liver failure and not from acquired immunodeficiency syndrome complications. Liver transplantation has been introduction in this patient population in several centres around the world. This review will discuss the current clinical status of liver transplantation in individuals suffering from human immunodeficiency virus infection.

Liver transplantation in patients with HIV infection

1. Liver transplantation for human immunodeficiency virus (HIV)-positive patients with end-stage liver disease in the era of highly active retroviral therapy has proven to be an effective treatment. The concerns of HIV progression have not been borne out by the growing worldwide experience. 2. CD4 counts are stable and HIV viral load is controllable with medication following liver transplantation. 3. Hepatitis C virus (HCV) coinfection in HIV-positive recipients is universal, but the severity of recurrence does not appear to be different from that in HIV-negative patients with HCV liver disease. 4. Complex pharmacokinetic interactions between the calcineurin inhibitors used for immunosuppression along with protease inhibitors are present, but management directed at recognizing the need for monitoring levels does not appear to increase the risk of toxicity. 5. The degree of immunosuppression from iatrogenic drug therapy and HIV does not lead to increased risk of infectious complications.

Liver transplantation in adults coinfected with HIV

OBJECTIVE

To report our experience of prospectively identifying and transplanting livers into HIV-positive patients.

DESIGN

Liver transplantation in HIV-positive patients remains controversial. The finding of HIV is usually considered a contraindication to any form of transplantation. Previously reported cases are few and refer to patients who tested HIV positive after they had their liver transplantations or who seroconverted in the posttransplantation period. This is, to our knowledge, the only report of patients who were known to be HIV positive at the time of decision for listing for transplantation.

METHODS

The medical records of five HIV-positive patients who received liver transplants in King's College Hospital, London, during a 5-year period (January 1995-December 1999) were reviewed. All five were known to be HIV positive at the time of listing for liver replacement. Three of them had end-stage liver disease due to hepatitis C (two of them had underlying Hemophilia A) while the other two had acute liver failure, one due to hepatitis B infection and one due to nonA-nonB-nonC hepatitis. In all but one patient the HIV infection had been asymptomatic.

RESULTS

All patients survived the immediate posttransplantation period, but the three patients with hepatitis C died of complications of recurrent hepatitis C between 6 and 25 months posttransplantation. The other two patients are currently alive 4 and 34 months posttransplantation with good graft function and without complications from their HIV infection.

CONCLUSION

The early outcome of liver transplantation in HIV seropositive patients can be good, and patients should not be excluded from transplantation if their liver disease determines their prognosis. More effective antiviral therapy for hepatitis C given posttransplantation, and for hepatitis B reinfection, should improve the longer-term outcome of HIV patients with end-stage liver disease due to hepatitis.

Shattered assumptions: time and the experience of long-term HIV positivity

This paper elucidates one of the main existential problems faced by people living with an HIV positive diagnosis-the disruption in their routine orientation towards time and the way in which this has the capacity to affect their lives more generally. Drawing upon research with people who have been living with an HIV positive diagnosis for at least five years, the paper aims to illuminate the "provisional existence" imposed upon the individual by the diagnosis and suggests that this ambiguous position underpins the many psychological and social problems confronted by them. In addition, however, the paper argues that in order for the individual to adjust effectively to living with an HIV positive diagnosis, it is necessary for him/her to develop alternative ways of conceiving and living within time, which "compensates" for the loss of the temporal assumptions that existed prior to diagnosis. The various ways in which individuals manage to do this are documented in this paper, as is the failure to do so and the psychosocial consequences ensuing from this. It is further argued that the ability to achieve compensatory temporal understanding is related to the individual's more general "existential orientational framework", of which temporal perspective is a constituent component. Finally, the implications of such findings are discussed for the targeting of appropriate intervention strategies.
