RESUMO

This article is the first description of a spontaneous hepatic rupture in a young bodybuilder with a history of clenbuterol and ephedrine alkaloid use. The patient presented with a sudden mid-epigastric pain and vomiting. Hemoglobin levels decreased a few hours later and a computed tomography scan was performed which revealed a rupture of the right liver capsule and hemoperitoneum. Two attempts at transarterial embolization did not control the bleeding and a right hemihepatectomy was performed. The pathological report identified a hepatic adenoma, a capsular tear and diffuse peliosis hepatis. The patient was discharged in a good condition after eleven days. Spontaneous hepatic ruptures are rare and life-threatening and are usually described in association with tumors, connective tissue diseases and gestosis. This article is a review of the available literature with regard to this condition, with a focus on its relation to peliosis hepatis and banned substance used by body image fanatics. The present case highlights the challenging diagnosis of this potentially fatal liver complication in a healthy appearing male, the risk associated with the online trade of performance enhancing drugs and its relation with peliosis hepatis

RESUMO

Peliosis hepatis (PH) is a condition involving benign tumors pathologically characterized by multiple blood-filled cavities, mostly affecting the liver and spleen. Androgenic-steroids are widely used in patients with bone marrow failure syndromes (e.g.: aplastic anemia) and these patients are at increased risk of developing PH. Although patients with PH are generally asymptomatic, PH can progress to liver failure and even fatal spontaneous intraabdominal hemorrhage. Therefore, early diagnosis is critical in order to prevent life-threatening complications of PH. We herein report a patient with PH which had been treated with danazol, who presented with liver dysfunction and multiple hepatic lesions on imaging studies at the time of diagnosis. Although the patient presented with disseminated intravascular coagulation (DIC), a bone marrow biopsy revealed no evidence of leukemic transformation. The patient was diagnosed as having danazol-induced PH, and these abnormalities spontaneously resolved after the discontinuation of danazol. PH is one of the most important complications of long-term administration of androgenic-steroids. Although the mechanisms remain unclear, the multiple blood-filled cavities characteristic of PH may be responsible for the development of DIC. Therefore, monitoring of coagulation markers might also be a key strategy for early diagnosis of PH.

RESUMO

Anabolic androgenic steroids (AAS) have been abused for decades by both professional and amateur athletes in order to improve physical performance or muscle mass. AAS abuse can cause adverse effects, among which are hepatotoxic effects. These effects include cholestatic icterus and possibly peliosis hepatis and hepatocellular carcinoma or adenoma. In particular, 17α-alkylated AAS appear to be hepatotoxic, whereas nonalkylated AAS appear not to be. The 17α-alkyl substitution retards hepatic metabolism of the AAS rendering it orally bioavailable. The mechanism responsible for the hepatotoxicity induced by 17α-alkylated AAS remains poorly understood. However, oxidative stress has been repeatedly shown to be associated with it. In this manuscript we present a hypothesis which describes a potential mechanism responsible for AAS-induced hepatotoxicity, based on several observations from the literature which suggest oxidative stress being a causal factor.

RESUMO

Peliosis hepatis (PH) is a rare vascular condition of the liver characterised by the presence of cystic blood-filled cavities distributed randomly throughout the liver parenchyma. PH should be considered in the differential diagnosis of women with a long history of use of oral contraceptives with suspected hypervascular lesions diagnosed by imaging, but with an unknown primary tumour. Because of the extensive use of oral contraceptives in the general female population worldwide, PH should be added to the differential diagnosis of suspected hypervascular liver lesions.

RESUMO

BACKGROUND/AIM: Hepatocellular carcinoma (HCC) is a frequent and aggressive malignancy associated with multiple environmental risk factors. The chemically-induced mouse model of diethylnitrosamine (DEN) provides useful insight into liver carcinogenesis, namely HCC. This work aimed to study the multistep process of hepato-carcinogenesis, providing a systematic framework for animal studies on this subject. MATERIALS AND METHODS: Male ICR mice were divided into six control and six DEN-exposed groups. Saline solution and DEN were injected intra-peritoneally, respectively, for eight consecutive weeks. Two groups (DEN vs. control) were euthanized at 8, 15, 22, 29, 36 and 40 weeks after the first administration. RESULTS: Hydropic degeneration, necrosis and apoptosis were acutely induced at eight weeks and onwards. Hyperplastic foci occurred at 29 to 40 weeks along with diffuse dysplastic areas and hepatocellular adenoma. Peliosis hepatis were also identified at 36 and 40 weeks. HCC were only noted at 40 weeks, showing characteristic histological features of malignancy. CONCLUSION: Results allowed sketching of a timeline of evolution of DEN-induced hepatic lesions in mice, from initial lesions to malignant neoplasms.

RESUMO

Cadmium is a known industrial and environmental pollutant. It causes hepatotoxicity upon acute administration. Features of cadmium-induced acute hepatoxicity encompass necrosis, apoptosis, peliosis and inflammatory infiltration. Gadolinium chloride (GdCl3) may prevent cadmium-induced hepatotoxicity by suppressing Kupffer cells. The effect of GdCl3 pretreatment on a model of acute cadmium-induced liver injury was investigated. Male Wistar rats 4-5 months old were injected intraperitoneally with normal saline followed by cadmium chloride (CdCl2; 6.5 mg/kg) or GdCl3 (10 mg/kg) followed by CdCl2 (6.5 mg/kg; groups I and II, respectively). Rats of both the groups were killed at 9, 12, 16, 24, 48 and 60 h after cadmium intoxication. Liver sections were analyzed for necrosis, apoptosis, peliosis and mitoses. Liver regeneration was also evaluated by tritiated thymidine incorporation into hepatic DNA. Serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were also determined. Hepatic necrosis, hepatocyte and nonparenchymal cell apoptosis and macroscopic and microscopic types of peliosis hepatis were minimized by gadolinium pretreatment. Serum levels of AST and ALT were also greatly diminished in rats of group II. Tritiated thymidine incorporation into hepatic DNA was increased in gadolinium pretreatment rats. Kupffer cell activation was minimal in both the groups of rats. Gadolinium pretreatment attenuates acute cadmium-induced liver injury in young Wistar rats, with mechanisms other than Kupffer cell elimination.

RESUMO

A 38-year-old female presented with symptoms of gastroenteritis including fatigue and epigastric pain. An abdominal ultrasound indicated on the basis of raised liver values showed multiple liver lesions. However, additional imaging using contrast-enhanced ultrasound (CEUS), computer tomography (CT) as well as a magnetic resonance tomography (MR) failed to clarify the diagnosis. A fine needle biopsy revealed the histological diagnosis of peliosis hepatis. After discontinuing oral contraceptive medication, follow-up showed a steady state with clinical well being for at least 24 months.Peliosis hepatis is a rare hepatic disorder involving "bloody cysts" in the liver. Aetiology and pathogenesis remain unclear, but medication or toxins as possible triggering factors are discussed. Different clinical courses have been reported, including total asymptomatic state, unspecific fatigue, epigastric pain, as well as fulminant cases with liver rupture and bleeding complications.

RESUMO

Introduction: Peliosis hepatis (PH) is an uncommon condition in pediatrics; however, it is one of the most serious complications associated with the long-term use of use of steroids. It is characterized by multiple blood-filled cavities, mostly involving the liver. Myelodysplastic Syndrome (MDS) is also a complex and infrequent hematological condition; it may transform into acute leukemia and its treatment requires medications that may lead to PH. Case Report: 13 year-old girl with MDS, refractory cytopenia type. A family donor for SCL was not available, therefore immunosuppressive treatment, steroids and transfusions were initiated. Due to metrorrhage, estrogen was used at high doses. She developed acute abdominal pain; abdominal ultrasound and CL scan showed PH and peritoneal bleeding. Oral contraceptives were decreased resulting in reduction of PH, but a new episode of uterine bleeding causing hypovolemic shock forced a hysterectomy in order to suspend estrogen treatment. Due to lack of response to treatment to SMD, she continued been treated with transfusions as needed, and died 32 months post diagnosis. Discussion: PH is an uncommon and life-threatening condition in children receiving prolonged treatment with steroids. Current modalities of SCL in patients with MDS will replace the need for steroids, thus avoiding this severe complication.


Introducción: La Peliosis Hepática (PH) es una condición muy infrecuente en pediatría, caracterizada por la presencia de múltiples cavidades sanguíneas en el parénquima hepático, asociada al uso prolongado de estrógenos o corticoides, El Síndrome Mielodisplásico (SMD) es una alteración hematológica compleja que puede evolucionar a leucemia y que puede requerir para su tratamiento medicamentos relacionados al desarrollo de PH. Caso Clínico: Niña 13 años, con SMD tipo citopenia refractaria, con dependencia transfusional, sin posibilidad de realizar Trasplante de progenitores hematopoyéticos (TPH) por falta de donante familiar compatible. Recibió transfusiones, inmunosupresores y corticoides por tiempo prolongado. Presentó metrorragias severas requiriendo estrógenos en altas dosis. Evolucionó con hemoperitoneo, diagnosticándose PH por ecografía y scanner abdominal. Al reducir dosis de estrógenos disminuyeron lesiones hepáticas, pero nuevo episodio de metrorragia con shock hipovolémico, obligó a realizar histerectomía para suspender estrógenos. Sin respuesta a tratamiento del SMD, se mantuvo con transfusiones según requerimiento y falleció a los 32 meses del diagnóstico. Discusión: La PH es una complicación grave, que podría evitarse con el desarrollo de nuevas técnicas de TPH que permiten contar con donantes no relacionados para el tratamiento de síndromes de falla medular como el SMD.

RESUMO

Androgens widely used in the treatment of bone marrow failure syndromes can in rare cases cause hepatic peliosis, a pathological entity characterized by multiple blood-filled cavities in the liver parenchyma. Bone marrow failure syndromes per se are associated with a low coagulation status, which is further magnified by bone marrow transplantation for aplastic anaemia due to deep thrombocytopenia. Both these conditions can cause bleeding; their combination is especially dangerous. We describe two cases of aplastic anaemia due to paroxysmal nocturnal hemoglobinuria and Fanconi syndrome, in which patients developed peliosis hepatis after prolonged treatment with androgens. One patient developed severe subcapsular bleeding, successfully treated with catheterization of the right hepatic artery and embolization of the bleeding site. The second patient bridged over deep post-transplant aplasia with high frequency platelet transfusions, and demonstrated an uncomplicated post-BMT course. We suggest avoiding or interrupting treatment with androgens in patients preparing for BMT.

RESUMO

Patients with inflammatory bowel disease have normal life expectancy and, due to modern immunosuppressive therapies, also a normal quality of life. Since mostly young people are affected, their social behaviour suits this environment. Alcohol binging is an increasingly disturbing factor among young people. We describe a patient with Crohn's disease, treated with azathioprine, who developed peliosis hepatis after three epsiodes of alcohol binging. Liver toxicity was not observed previously during the course of the treatment. Azathioprine-induced peliosis hepatis is thought to be idiosyncratic in humans. From animal studies, however, it is clear that hepatic depletion of glutathione leads to azathioprine toxicity to the sinusoidal endothelial cells. Damage of these cells causes peliosis hepatis. Since alcohol binging leads to hepatic glutathione depletion, we conclude that in our patient the episodes of binging have reduced liver gluathione content and therefore this has increased azathioprine toxicity causing peliosis hepatis. The problem of alcohol binging has not yet been addressed in IBD patients undertaking immunosuppressive therapy. This should be reviewed in future considerations regarding patients advice.

RESUMO

Macroscopic and microscopic types of peliosis hepatis, time pattern, and correlation with hepatocyte and sinusoidal cell apoptosis were investigated. Male Wistar rats were injected with a dose of cadmium (6.5 mg CdCl(2)/kg body weight, intraperitoneally; group I). Putrescine (300 micromol/kg body weight, intraperitoneally; group II) was injected at 2, 5, and 8 hours and vascular endothelial growth factor (VEGF; 400 ng/animal, intravenously; group III) at 2 hours. Animals from each group were humanely killed 0, 6, 12, 24, 48, or 60 hours after cadmium intoxication. Liver tissue was histologically assessed for necrosis, apoptosis, and peliosis. Apoptosis was also quantified by the TUNEL assay for hepatocytes and nonparenchymal liver cells. The discrimination between hepatic cell subpopulations was done histochemically. Sinusoidal cell apoptosis and macroscopic peliosis hepatis evolved in a monophasic pattern and correlated closely. Putrescine or VEGF administration totally reversed macroscopic peliosis. Putrescine exerted a major protective effect on hepatocytes, whereas the protective effect of VEGF was more pronounced for nonparenchymal liver cells. Microscopic peliosis also evolved in a monophasic pattern preceding macroscopic type. The extent of the lesion was reduced by putrescine and almost totally reversed by VEGF. Macroscopic peliosis progresses as a compound lesion closely correlating with nonparenchymal cell apoptosis. Both hepatocyte and nonparenchymal cell injury are prerequisites for the genesis of the lesion. Microscopic peliosis precedes macroscopic peliosis and up to a degree seems to be independent of initial hepatocyte injury, but it seems to depend on nonparenchymal cell injury.

RESUMO

The hepatoprotective effect of putrescine against cadmium liver injury was investigated. Male Wistar rats were injected with a dose of cadmium (6.5 mg CdCl(2)/kg bodyweight, intraperitoneally). Normal saline (group I) or putrescine (300 micro mol/kg bodyweight; group II) were injected 2, 5 and 8 h later. A number of animals of both groups were killed 0, 12, 16, 24, 48 or 60 h after cadmium intoxication. Liver tissue was histologically assessed for necrosis, apoptosis, peliosis, mitoses, and inflammatory infiltration. Apoptosis was also quantified by the TUNEL assay for hepatocytes and nonparenchymal liver cells. The discrimination between hepatic cell subpopulations was achieved histochemically. The mitotic index in hematoxylin-eosin-stained sections and by the immunochemical detection of Ki67 nuclear antigen, (3)H-thymidine incorporation into hepatic DNA, and hepatic thymidine kinase activity were all used as indices of liver regeneration. Both hepatocyte apoptosis and liver necrosis evolved in a biphasic temporal pattern. Nonparenchymal cell apoptosis and peliosis hepatis evolved in a monophasic pattern and were correlated closely. Putrescine administration totally reversed liver necrosis and hepatocyte apoptosis. The time profile of nonparenchymal apoptosis was altered and peliosis hepatis was also totally attenuated. In conclusion, putrescine protected hepatocytes and modulated the mechanism of cadmium-induced acute hepatotoxicity.

RESUMO

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a widespread, persistent, and highly toxic environmental pollutant. The most TCDD-sensitive and the most TCDD-resistant rat strains (Long-Evans [Turku/AB] and Han/Wistar [Kuopio], respectively) were crossbred to separate the alleles of two genes (Ahrand an unidentified gene "B") mediating resistance against TCDD toxicity. During crossbreeding, a new type of toxicity in livers of both sexes was detected, characterized macroscopically by intense dark green to black color and swelling that appeared most frequently after a large dose (300 micro g/kg or more as a single intragastric dose) and a follow-up period of more than three weeks. Therefore, studies were undertaken to identify the causative pigment chemically and to examine the hepatotoxicity histologically. The pigment fractions were separated by thin layer chromatography and then analyzed by HPLC and electrospray mass spectrometry. The pigment was found to consist of biliverdin and several biliverdin-related compounds. In liver histopathology carried out on male rats, progressive sinusoidal distension and hepatic peliosis with membrane-bound cysts were seen. The clinical manifestations of pigment accumulation were recorded most often in intermediately resistant rat lines such as line B (homozygous for the gene B), but never occurred in rats expressing only the Han/Wistar (Kuopio)-type Ah receptor with an altered transactivation domain structure.
