Delayed and prolonged cholestatic hepatitis with ductopenia after long-term ciprofloxacin therapy for Crohn's disease

Ciprofloxacin, a fluorinated quinolone, is a powerful antibiotic widely used for its broad spectrum of activity in ambulatory and long-term care setting. Until now, ciprofloxacin administration has been associated with a few cases of acute, sometimes cholestatic jaundice or fulminant hepatic failure believed mainly related to idiosyncratic hypersensitivity. We report a case of delayed and prolonged cholestatic hepatitis with ductopenia occurring after 6 months of treatment in a patient with Crohn's disease. This observation suggests the potential for the drug to induce long-term likely dose-related severe hepatotoxicity.     

Celecoxib-induced cholestatic liver failure requiring orthotopic liver transplantation

Selective cyclooxygenase-2 （COX-2） inhibitors are widely used due to their efficacy and good safety profile. However, recent case reports have described varying degrees of liver injudes associated with the use of COX-2 inhibitors. We report the case of a patient who developed acute cholestatic hepatitis progressing to hepatic failure requiring liver transplantation, following a 3-d course of celecoxib for treatment of generalized muscle aches and pains. The clinical presentation, the laboratory data, as well as the liver histopathology were supportive of the putative diagnosis of drug induced liver injury.     

Cholestatic hepatitis with severe systemic reactions induced by trimethoprim-sulfamethoxazole

Trimethoprim-Sulfomethoxazole (TMP-SMX) related hepatotoxicity and associated severe systemic reaction are not frequent and documented only in case reports. We report a case of a 30-year-old man, who underwent a 15-day therapy with TMP-SMX for urinary tract infection and two weeks later developed acute cholestatic hepatitis, fever and a skin rash followed by severe systemic reaction. He was admitted in Intensive Care unit and with supportive therapy and prednisolone administration, he showed subsequent improvement over a period of few days. He had fully recovered months later. All tests for other causes of liver disease were negative and his liver biopsy showed evidence of drug-induced hepatic injury.     

Four cases of hepatitis B virus-related fibrosing cholestatic hepatitis treated with lamivudine

Fibrosing cholestatic hepatitis (FCH) is a rare and extremely severe form of hepatitis B virus (HBV) infection. This condition was originally described in HBV-infected recipients after a liver transplantation. Recently, FCH has been reported not only in liver transplant recipients, but also in other immunosuppressed patients. It is characterized clinically by cholestatic hepatic dysfunction, and pathologically by severe periportal fibrosis, cholestasis, widespread balloon degeneration of hepatocytes, and only a mild infiltration of inflammatory cells. Without treatment, FCH is universally fatal within a few months of diagnosis. There have been only two isolated case reports of FCH with long-term patient survival, and one case report with treatment failure after lamivudine therapy. Because of the rarity of this clinical entity, the therapeutic efficacy of lamivudine in patients with FCH cannot be evaluated systematically. Here, we present four patients with HBV-related FCH treated with lamivudine. One received antineoplastic therapy for acute lymphoblastic leukemia, and the other three were renal graft recipients. Two patients who developed FCH after a renal transplantation survived with an improvement in liver function and were followed up for 20 and 30 months, respectively, and were found to be in good health. However, the other two patients died of sepsis, possibly as a consequence of the immunosuppression with hepatic failure despite lamivudine treatment. Our experience suggests that lamivudine can alter the grave natural history of FCH.     

CASE REPORT: Fatal Cholestatic Liver Failure Associated with Gemcitabine Therapy

Drug-induced hepatotoxicity accounts for more than a third of the cases of acute liver failure in the United States. In complex medical conditions, the diagnosis of drug-induced liver injury may be confounding and, specifically, the potential hepatotoxicity of chemotherapeutic agents may be easily overlooked. Two fatal cases of cholestatic hepatotoxicity have been previously reported, clearly implicating gemcitabine therapy. We report a third fatal case of cholestatic liver failure that we think is strongly linked to the use of gemcitabine. This chemotherapeutic agent is a fluorine analog with broad-spectrum antitumor activity commonly used in the treatment of breast, lung, prostate, and cervical cancer. The case we report is of a 45-year-old woman with a history of metastatic breast cancer to her spine. The patient was in remission for two years before she presented with a compensated mixed hepatitis of mild to moderate severity. Inpatient work-up found metastases to the right humerus and inferior pubic ramus, but none in the liver. Gemcitabine and carboplatin therapy was initiated for relapse of breast cancer. The patient's liver enzyme elevation diminished, but did not normalize before the start of chemotherapy. She received four courses of gemcitabine/carboplatin and subsequently presented with decompensated, severe cholestatic hepatitis. Transjugular liver biopsy displayed marked cholestasis and hepatocellular injury consistent with drug-induced hepatoxicity. Gemcitabine has been extensively studied in the oncology literature and at this time is thought to be a low-risk hepatotoxin causing hepatic adaptation and transient, reversible liver enzyme elevation, rarely leading to termination of gemcitabine therapy for solid tumors. We believe that gemcitabine therapy, particularly in the setting of preexisting liver injury or metastases to the liver, increases the relative risk of severe and potentially fatal hepatic injury possibly by idiosyncratic and dose-dependent mechanisms. We recommend careful monitoring and dose adjustment of gemcitabine in patients with abnormal liver function tests or evidence of hepatic metastases until further study clarifies this issue.     

Acute renal failure in Plasmodium malariae infection

We report an unusual case of transfusion-transmitted malaria which remained undiagnosed for several months in an Italian woman splenectomised and polytransfused for thalassaemia major. The infecting species was Plasmodium malariae, and the patient developed acute renal failure, severe thrombocytopenia, and hepatic failure. Treatment with chlorochine was followed by a slow, but complete recovery of renal function.     

Cholestatic jaundice associated with the use of metformin

We report a patient who developed cholestatic jaundice shortly after initiation of treatment with metformin hydrochloride. Ultrasound of the liver and abdominal CT were normal. An ERCP showed normal biliary anatomy. A percutaneous liver biopsy was obtained showing marked cholestasis, with portal edema, ductular proliferation, and acute inflammation. Metformin hydrochloride was discontinued, and the patient's jaundice resolved slowly over a period of several months. Given the onset of his jaundice 2 wk after the initiation of metformin, we believe that this case represents an example of metformin-associated hepatotoxicity, the first such case reported.     

Subcapsular hematoma of the liver and pylethrombosis in the setting of cholestatic liver injury

We describe a subcapsular hematoma of the liver and pylethrombosis in a patient who developed cholestasis 4 days after severe burn injury. On the 44th hospital day, severe anemia suddenly appeared with no determinable cause. This was the initial manifestation of hepatic hematoma. Cholestatic liver injury of unknown cause lasted throughout the clinical course. The patient subsequently died of hepatic failure 27 months after the burn injury. An autopsy confirmed pylephlebitis and pylethrombosis, which were considered to have contributed to the hepatic failure. This was a rare case of hepatic hematoma and pylephlebitis and pylethrombosis that developed after burn injury.     

Sulfasalazine-induced Fulminant Hepatic Failure and Necrotizing Pancreatitis

We report the simultaneous development of fulminant hepatic failure and necrotizing pancreatitis in a patient treated with sulfasalazine. The patient had recent onset of ulcerative colitis. A diffuse skin rash and fulminant hepatic failure developed 2–3 wk after initiation of sulfasalazine therapy. An exploratory laparotomy revealed severe necrotizing pancreatitis with phlegmon, in addition to confluent hepatic necrosis. Electron microscopy of the liver was consistent with drug injury. The patient died after 2 months of hospitalization. This is the first reported case of the concurrent development of these complications associated with sulfasalazine hypersensitivity. These potential adverse effects of sulfasalazine should be considered when using this agent.     

Fulminant liver failure associated with T-cell non-Hodgkin's lymphoma and hepatitis C virus: a case report

Hematological malignancies can affect the liver, without producing severe hepatic involvement. We report the case of a 57-year-old man with hepatitis C virus infection and mild chronic hepatitis without antiviral treatment, who developed an aggressive T-cell non-Hodgkin's lymphoma confirmed by histological studies including liver, lymph nodes and bone marrow. The patient developed massive hepatic infiltration and acute liver failure. Rescue chemotherapy was administered but the patient died soon after with severe lactic acidosis. The immunopathological features of this association and the few reports of cases presenting with acute liver failure are reviewed.     

Dress syndrome and fulminant hepatic failure induced by lamotrigine

Lamotrigine is a non-aromatic antiepileptic drug. Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a severe idiosyncratic reaction to drugs, especially anti-epileptic drugs. Associated clinical features include cutaneous eruption, fever, multiple peripheral lymphadenopathies, and potentially life-threatening damage of one or more organs. We report a case of DRESS syndrome induced by lamotrigine presenting with a hypersensitivity syndrome and fulminant hepatic failure requiring liver transplant. A 21-year old female patient presented an episode of seizure with loss of conscience. CT and EEG studies performed were normal. Treatment with lamotrigine was prescribed. In the course of 30 days, the patient developed skin lesions, pruritus, cholestatic hepatitis, and systemic symptoms-fever, lymphadenopathies, extensive exfoliative erythematous maculopapular rash, and jaundice. Serologic and laboratory tests showed no other causes responsible for the clinical spectrum. Hematologic tests revealed peripheral eosinophilia. Fulminant hepatic failure was diagnosed and an orthotopic liver transplant was performed. Histologic sections of the ex-planted liver demonstrated submassive hepatic necrosis, with the remnant portal spaces and lobules showing a mixed inflammatory infiltrate with lymphocytes and eosinophils. Lamotrigine treatment has been associated with multiorgan failure, DRESS syndrome, acute hepatic failure, and disseminated intravascular coagulation. In conclusion, we suggest that these potentially fatal side effects should be considered in any patient with clinical deterioration following administration of this drug.     

Liver Failure after Hydroxycut? Use in a Patient with Undiagnosed Hereditary Coproporphyria

We report the case of a young male presenting with cholestatic liver failure. After an extensive workup, the etiology of the liver failure was determined to be due to hereditary coprophorphyria (HCP). The inciting event was the use of Hydroxycut™, an over-the-counter supplement to promote weight loss that has been reported to cause oxidative liver injury in vulnerable populations. Although HCP is a rare cause of cholestatic liver failure, it is treatable if diagnosed correctly and in a timely manner. In this clinical vignette, we discuss a case that highlights the genetic susceptibility to disease that can be unmasked by environmental exposures. We also review the relevant literature on Hydroxycut™ and how it can affect hepatic function.Key words: porphyria, liver failure, herbal supplement use     

Life-Threatening Drug-Induced Liver Injury in a Patient with β-Thalassemia Major and Severe Iron Overload on Polypharmacy

Abstract

A 20-year-old male affected by transfusion-dependent β-thalassemia (β-thal), was prescribed intensive chelation therapy with deferoxamine (DFO) and deferiprone (DFP) because of severe hepatic and cardiac iron overload and β-blocker and warfarin to manage a previous event of atrial fibrillation (AFib) and heart failure. After a few months, he developed critical liver failure, renal tubulopathy and severe electrolyte imbalance. Laboratory and instrumental evaluations were performed to carry out differential diagnosis of acute liver failure and an exclusion diagnosis of drug induced liver injury (DILI) was made. The cholestatic pattern suggested warfarin as the main causative agent and polypharmacy, liver iron overload and heart failure as aggravating factors. Warfarin is a drug commonly prescribed in thalassemia patients who often need polypharmacy for the management of anemia- and iron-related complications. Strict monitoring and multidisciplinary approaches are mandatory to avoid preventable mortality in this fragile population.     

CASE REPORT: Fibrosing cholestatic hepatitis after living related-donor renal transplantation

A 43-year-old man underwent living related-donor renal transplantation because of chronic renal failure in 1991. During the transplant period, both donor and recipient were seronegative for hepatitis B surface antigen (HBsAg). The donor was seropositive for antibody to hepatitis B surface antigen (anti-HBs) due to hepatitis B virus (HBV) vaccination. After transplantation, FK506 and methylprednisolone had been administered to the patient as immunosuppressants. In 1993, HBsAg appeared in his serum. His alanine aminotransferase level elevated gradually during 1995 and then in 1996, general fatigue, ascites and jaundice developed. At this time his serum was positive for hepatitis B e antibody, contained more than 100000 Meq/mL HBV-DNA and 100% precore mutant. Despite subsequent intensive therapy, liver dysfunction progressed and this patient died of hepatic failure 2 months following admission. At autopsy, the liver exhibited cholestasis, fibrosis extending from the portal tracts, mild inflammation and hepatocytes with a ground-glass appearance. In addition, HBsAg and hepatitis B core antigens had accumulated in the hepatocytes. Consequently, the final diagnosis was fibrosing cholestatic hepatitis (FCH) due to precore mutant HBV infection contracted after renal transplantation. It is unclear when and where the recipient liver became HBV infected. Nevertheless, after renal transplantation, while receiving immunosuppressive drugs, HBV appeared to have the potential to cause hepatic failure and FCH may have been a fatal complication for the recipient.     

Safety of imatinib in chronic myeloid leukemia in blastic crisis presenting as cholestatic jaundice

Acute leukemia presenting as cholestatic jaundice is rare. It can occur due to granulocytic sarcoma compressing the bile ducts in case of acute myeloid leukemia. Rarely, diffuse infiltration of the liver sinusoids by the leukemic blasts can present as cholestatic jaundice. We report a case of chronic myeloid leukemia in lymphoid blast cell crisis presenting with severe cholestatic jaundice due to diffuse infiltration of the liver sinusoids with lymphoblasts. This patient tolerated imatinib well and, coinciding with the hematological response, there was marked reduction in the cholestasis due to blast clearance from the hepatic sinusoids. He was subsequently treated with combination chemotherapy and achieved morphological and cytogenetic remission.     

Fatal liver failure in an adult patient with acute lymphoblastic leukemia following treatment with L-asparaginase

L-Asparaginase is commonly used in combination chemotherapy of both pediatric and adult acute lymphoblastic leukemia. The majority of adverse effects are hypersensitivity reactions, but serious liver injury may also occur. It has been shown that treatment with L-asparaginase can be associated mainly with macrovesicular hepatic steatosis which may be accompanied by alterations in lipid metabolism. So far, the mechanism for liver injury associated with L-asparaginase is not known. We report here an adult patient who developed mixed liver injury and predominantly microvesicular hepatic steatosis while being treated with L-asparaginase for acute lymphoblastic leukemia. The patient developed liver failure and died due to multiorgan failure. Both impaired liver mitochondrial function and alterations in very-low-density lipoprotein metabolism and secretion are discussed as two possible mechanisms explaining the findings observed in this patient.     

Cimetidine-induced liver injury. Report of three cases

Cimetidine-induced liver injury has only very rarely been reported. Three patients are described who developed signs of hepatic damage after the institution of cimetidine therapy. Transient signs of acute liver failure were noticed in one patient. Histologically, a cytotoxic type of injury with centrilobular confluent and bridging portal-central necrosis, accompanied by a mixed mono- and polymorphonuclear infiltrate with signs of cholangiolitis in the portal tracts was observed in two patients, whereas a hepatocanalicular type of cholestatic hepatitis was noticed in another patient. It is proposed that the mechanism of cimetidine-induced liver injury may vary in different patients: it may be due either to a 'metabolic idiosyncrasy' because of the production of hitherto unknown toxic metabolites or to a hypersensitivity reaction.     

Fatal Massive Hepatic Necrosis: A Probable Hypersensitivity Reaction to Sulfasalazine

Sulfasalazine (salicylazosulfapyridine) is a commonly prescribed oral medication for inflammatory bowel disease. We report a case of a 15-yr-old boy with ulcerative colitis who developed a generalized hypersensitivity reaction with a serum sickness-like syndrome and severe hepatotoxicity while taking sulfasalazine, perphenazine, and amitriptyline. The injury to the liver persisted for 5 months after withdrawal of the drugs, and the patient died of terminal hepatic failure with massive hepatic necrosis. Severe hepatic toxicity to sulfasalazine is uncommon, but it can be fatal.     

Parvovirus B19 induced hepatic failure in an adult requiring liver transplantation

Parvovirus B19 induced acute hepatitis and hepatic failure have been previously reported, mainly in children. Very few cases of parvovirus induced hepatic failure have been reported in adults and fewer still have required liver transplantation. We report the case of a 55-year-old immunocompetent woman who developed fulminant hepatic failure after acute infection with Parvovirus B19 who subsequently underwent orthotopic liver transplantation. This is believed to be the first reported case in the literature in which an adult patient with fulminant hepatic failure associated with acute parvovirus B19 infection and without hematologic abnormalities has been identified prior to undergoing liver transplantation. This case suggests that Parvovirus B19 induced liver disease can affect adults, can occur in the absence of hematologic abnormalities and can be severe enough to require liver transplantation.
