Thirty children received 35 liver transplants for fulminant or late-onset liver failure between March 1988 and May 1993. Aetiology included non-A non-B hepatitis in 12, Wilson's disease in 8, drug-induced hepatic failure in 6, hepatitis B in 1, hepatitis A in 1, tyrosinaemia in 1 and congenital haemochromatosis in 1. Three patients were retransplanted, one each for hepatic artery thrombosis, non-A non-B graft reinfection, and chronic rejection. Two of these three patients received a third transplant for chronic rejection and hepatic artery thrombosis. One patient in the retransplant group survived. Overall, graft and patient survival at a mean follow-up of 17 months were 49% and 57%, respectively. Mortality was related to vascular complications in three patients (hepatic venous obstruction, portal vein thrombosis and hepatic artery thrombosis). Two patients died of primary sepsis (cerebral aspergillosis and cytomegalovirus (CMV) pneumonitis in association with graft-versus-host disease). Systemic sepsis and multiorgan failure was documented as a cause of death in four children and sepsis in association with chronic rejection in a further three patients. One child died of respiratory failure 4 weeks after transplantation. Mortality in eight children less than 2 years was 75% and this was significantly greater than for older children (P < 0.003, Mantel Cox). Earlier referral, even in the absence of a definitive diagnosis and particularly in children under 2 years is advisable and may improve survival.

Unconventional therapies have become popular in paediatric and adolescent populations. It is therefore important to define their risks. The aim of this systematic review was to summarise the recent evidence. Computerised literature searches were carried out in five databases to identify all recent reports of adverse events associated with unconventional therapies in children. The reports were summarised in narrative and tabular form. The results show that numerous case reports and several case series have been published since 1990. Investigations of a more systematic nature are, however, rare. Most of the adverse events were associated with herbal medications. Inadequately regulated herbal medicines may contain toxic plant material, be contaminated with heavy metals, or be adulterated with synthetic drugs. The adverse events included bradycardia, brain damage, cardiogenic shock, diabetic coma, encephalopathy, heart rupture, intravascular haemolysis, liver failure, respiratory failure, toxic hepatitis and death. A high degree of uncertainty regarding a causal relationship between therapy and adverse event was frequently noted. The size of the problem and its importance relative to the well-documented risks of conventional treatments are presently unknown. Several unconventional therapies may constitute a risk to the health of children and adolescents. At present, it is impossible to provide reliable incidence figures. It seems important to be vigilant and investigate this area more systematically.

The centrilobular liver cell necrosis observed in hypoxic hepatitis is generally attributed to failure of hepatic blood perfusion. Accordingly, this injury of the liver is commonly recognized under the terms "shock liver" or "ischemic hepatitis." During a 10-year period, 142 episodes of hypoxic hepatitis were consecutively identified in the intensive care unit of a general hospital, and the clinical, biological, and hemodynamic parameters were prospectively collected on individual files. We conducted the current study to assess retrospectively the role of the hemodynamic mechanisms of tissue hypoxia: ischemia, passive venous congestion, and hypoxemia. Among the 142 episodes of hypoxic hepatitis, 138 were separated in 4 main groups based on clinical features: decompensated congestive heart failure (80 cases), acute cardiac failure (20 cases), exacerbated chronic respiratory failure (19 cases), and toxic/septic shock (19 cases). An elementary hemodynamic evaluation, including blood pressure, central venous pressure, and arterial blood gas analysis, was carried out in every episode and a more complete hemodynamic assessment through pulmonary artery catheterization was performed in 61 episodes. The hemodynamic mechanisms responsible for hypoxic hepatitis were different in the 4 groups. In congestive heart failure and acute heart failure, the hypoxia of the liver resulted from decreased hepatic blood flow (ischemia) due to left-sided heart failure and from venous congestion secondary to right-sided heart failure. In chronic respiratory failure, liver hypoxia was mainly due to profound hypoxemia. In toxic/septic shock, oxygen delivery to the liver was not decreased but oxygen needs were increased, while the liver was unable to use oxygen properly. In all conditions underlying hypoxic hepatitis, except toxic/septic shock, a shock state was observed in only about 50% of the cases. Therefore, the expressions "shock liver" or "ischemic hepatitis" are misleading and should be replaced by the more general term "hypoxic hepatitis."

We present a case of an obese young man who developed ischemic hepatitis, severe coagulopathy, acute renal failure, and encephalopathy. Heart failure and hypovolemia were absent. Oxygen arterial saturation was very low, between 77% and 99% during the day, with no history of respiratory failure. A diagnosis of obstructive sleep apnea was made clinically and confirmed by performing formal polysomnography. The polysomnographic study showed multiple episodes of apneas and hypopneas with severe oxygen desaturation. The patient was treated with continuous positive airway pressure through a nose mask and clinical manifestations related to profound nocturnal desaturation were ameliorated. He was discharged 32 days after admission with normal results of laboratory tests. This case report is presented to support the hypothesis that hypoxic hepatitis was directly related to severe arterial hypoxemia.

Adenoviruses (AdV) are opportunistic pathogens that can lead to severe infections and respiratory failure (acute respiratory distress syndrome, ARDS) with high mortality in immunosuppressed patients. Cidofovir (CDV) has been used in adenoviral disease in bone marrow transplant recipients. Two pediatric liver transplant recipients with disseminated adenoviral disease and ARDS were treated with reduction of immunosuppression, CDV, and inhaled nitric oxide (iNO). CDV 1 mg/kg was given three times per week intravenously with intravenous hydration and oral probenecid. Viral suppression and clinical improvement was achieved. AdV hepatitis did not occur, and graft function was preserved, although acute rejection occurred in both patients. Adverse effects were mild and transient not requiring dose modification. Severe hypoxemia was reversed with iNO 10-20 p.p.m. CDV treatment of AdV infections in organ transplant recipients and other immunocompromised patients should be further investigated in prospective studies.

We report an immunocompetent woman with multisystem organ failure following herpes simplex virus type 2 (HSV-2) hepatitis. After she initially responded to intravenous acyclovir, she was switched to oral valacyclovir. She developed respiratory failure and opportunistic infections and died. Autopsy confirmed disseminated HSV infection, and lung tissue grew acyclovir-resistant HSV-2.

Adult living donor liver transplantation (ALDLT) is an accepted procedure to overcome the organ shortage. The advantages of ALDLT must be balanced against the first concern of donor safety. We analyzed the results of our early experience among a series of eight ALDLT performed between April 2001 and October 2003. All patients were listed as United Network for Organ Sharing UNOS status 2b and 3. Transplant recipients consisted of four men and four women. The living donors included four sons, three daughters, and one son-in-law (ages 20 to 45 years). One donor was anti-HBc-positive and negative for hepatitis B virus-DNA by polymerase chain reaction analysis in serum and in liver tissue. GR/WR >0.8 and fatty liver <10% were considered suitable for the hepatectomy. Residual left lobe volume was at least 33%. No exogenous blood and blood products were transfused into the donors and a cell-saver device was used in all donors (blood loss 490 +/- 160 mL). All procedures were right lobe hepatectomy; in one case the middle hepatic vein was withdrawn with the right graft. The mean ischemia time was 1.5 +/- 0.5 hours. All donors survived the procedure. Median hospital stay was 8.5 +/- 2.1 days in all donors but one who had a long stay because of drug-related hepatitis. One graft was lost and one donor aborted because of preoperative overestimated volumetry. Complications were experienced by two donors (25%). Five recipients (62.5%) experienced major complications; one patient underwent retransplantation because of donor graft loss. Two biliary and two vascular complications (33.3%) occurred in three patients. No perioperative death occurred. Two patients died at 9 and 10 months after transplant because of heart and respiratory failure in the first case and tumor recurrence in the second. One-year actuarial survival is 75%. ALDLT using right lobe has gained acceptance to overcome the organ shortage. Donor selection criteria must be stringent with respect to residual donor hepatic volume, steatosis, and liver function.

We describe an unusual case of unexpected dyspnoea following transfusion of fresh frozen plasma (FFP) in a previously-well 72-year-old woman. Our patient was scheduled for an ultrasonographically-guided liver biopsy for work-up for autoimmune hepatitis. She was given FFP to correct a prolonged prothrombin time. Shortly after the transfusion was initiated, she started coughing and became progressively dyspnoeic. Clinically, she was tachypnoeic with diffuse bilateral crepitations, and rapidly went into respiratory failure. She was intubated and placed on mechanical ventilation. Her condition improved and she was extubated by the second day, with no long-term pulmonary sequelae. A diagnosis of transfusion-related acute lung injury (TRALI) was made, based on the rapidity of onset and association with transfusion. This was confirmed by the findings of anti-human leukocyte antigen antibodies in both the patient and recipient blood. Our case highlights this important but under-recognised condition. The incidence, diagnosis and management of TRALI are also discussed.

Hypoxic hepatitis better known under the terms of ischemic hepatitis or shock liver is the clinical manifestation of an acute liver cell necrosis consecutive to liver hypoxia. The clinical syndrome is defined as a massive but rapidly resolutive increase in serum aminotransferase activities (AT) occurring in a clinical setting of hemodynamic failure. Actually, when confronted to a case of massive increase in serum AT in the setting of cardiac or respiratory failure, the diagnosis of HH may be assumed without liver biopsy if another cause of hepatocyte necrosis such as viral hepatitis or drug induced hepatitis may be excluded. To our opinion, in these patients often aged and in poor general condition, it is particularly important to exclude herpes simplex virus infection and paracetamol intoxication. In case of doubt, a mere ultrasonography of the liver will be helpful. Indeed the majority of these patients will have a dilation of hepatic veins due to passive congestion of the liver. There is no specific liver therapy and the prognosis is poor depending on the severity of the underlying condition. In this point of view, we report what could be of interest for the hospital clinician.

Doxycycline is a commonly prescribed medication for the management of acne vulgaris. Severe adverse reactions to this medication are uncommon. We describe an unusual case of a 20-year-old female who experienced a life-threatening hypersensitivity reaction, including fever, lymphadenopathy, hepatitis, nephritis and severe pneumonitis with respiratory failure following oral administration of doxycycline for facial acne.
