Clozapine-induced cholestatic jaundice: a case report

We report on a patient who became jaundiced during treatment with clozapine (Leponex). Histologically, cholestatic hepatitis with single-cell necroses of hepatocytes and infiltration of the portal zones with eosinophilic granulocytes were found. The patient recovered after discontinuation of clozapine, and liver function tests returned to normal within 4 weeks. This adverse effect of clozapine suggests that this "atypical" tricyclic neuroleptic resembles the phenothiazines both with regard to therapeutic spectrum and side effects.

Duodenal tuberculosis presenting as gastric outlet obstruction: A case report

Gastric outlet obstruction is commonly associated with malignancies and peptic ulcer disease. However, when no malignancy is seen and the patient is nonresponsive to conventional peptic ulcer treatment, other etiologies need to be explored. We report a case of gastric outlet obstruction due to duodenal tuberculosis. The patient is a 31 year old male who presented with 1 year history of recurrent epigastric pain and an a cute episode of vom iting. Endoscopy revealed duodenal stricture. Computed tomography scan showed pyloro antral thickening. The patient was referred to the surgery service and underwent an exp lor atory laparotomy and gastrojejunostomy. A duodenal mass and calcified lymph nodes were noted on exploration and biopsy revealed a tuberculous origin. The patient was started on anti-tuberculosis medications and had impro ved on discharge. Gastroduodenal tuber culosis is rare and pyloric stenosis resulting from tuber culosis is even rarer. This, however, should be consid ered in patien ts who come from areas where the dise ase is endemic.     

Gastric tuberculosis presenting as non healing ulcer: A case report

Tuberculosis is a major health problem in India. Gastrointestinal tuberculosis is the sixth most common causes of extrapulmonary tuberculosis and it mostly involves the ileocaecal region. Primary gastric tuberculosis in immunocompetent person is very rare. Stomach as its site is rare and is the sixth most common site of gastrointestinal tuberculosis. It mostly presents as a cases of non healing ulcer or gastric outlet obstruction. Yield of endoscopic biopsies for granuloma is low due to submucosal location of these lesions and mostly they are diagnosed after surgical intervention. We report a case of isolated gastric tuberculosis in a middle age immunocompetent female who present as a cases of non healing ulcer and responded well to standard antitubercular treatment. A high index of its suspicion should be kept in mind in any chronic infiltrative lesions of stomach like non healing ulcers and gastric outlet obstruction for its early diagnosis and treatment.     

Acute hepatitis E virus infection presenting as a prolonged cholestatic jaundice

Hepatitis E virus (HEV) is an enteric virus that usually causes a self-resolving hepatitis; although, it may be fatal, especially in pregnant women. Although HEV is endemic in Israel, there have been no recent local outbreaks. We report the case of a 70-year-old man who presented with painless jaundice. Ultrasound and abdominal computed tomography scan revealed gallstones, with no evidence of cholecystitis and no dilatation of the intra-or extrahepatic bile ducts. An open cholecystectomy was performed with intraoperative cholangiography. There was no evidence of choledocholithiasis. A subsequent endoscopic retrograde cholangiopancreatography was normal. His bilirubin level subsequently increased to a maximum of 25 mg/dL, and his gamma-glutamyl-transferase level reached 1,400 U/L. There was no evidence of any autoimmune or metabolic disease, and routine viral serology was normal except for immunoglobulin G to hepatitis A virus. A liver biopsy revealed an acute cholestatic picture. The jaundice resolved slowly after a period of 6 months. Hepatitis E virus RNA was isolated from the acute-phase serum and was not detectable in the convalescent serum. This case is a unique example of chronic cholestatic jaundice that we think is caused by acute HEV infection.     

Fosinopril-induced prolonged cholestatic jaundice and pruritus: first case report

We report a case of fosinopril-induced prolonged cholestatic jaundice and pruritus in a 61-year-old man, with no previous hepatobiliary disease, who presented with asthenia, jaundice and itching 3 weeks after starting fosinopril therapy. Other drugs taken by the patient were not considered probable causes. The diagnostic evaluation showed no biliary obstruction and other possible causes of intra-hepatic cholestasis were excluded. Liver biopsy showed cholestasis without bile duct damage. The disease ran a severe course during the 2 months of hospitalization, with prolonged itching for 6 months, eventually controlled with oral naltrexone. Jaundice subsided after 4 months, with anicteric cholestasis persisting for more than 18 months. Similar occurrences have been reported with other inhibitors of angiotensin-converting enzyme (mostly captopril), but this is the first case of an important adverse reaction to fosinopril.     

Hepatic cysts of periductal gland origin presenting as obstructive jaundice

Retention cysts may arise from periductal glands of the hepatic ducts. These cysts are usually asymptomatic. Presented here is the first case with jaundice secondary to obstruction of the hepatic ducts by periductal cysts. Two other cases involved asymptomatic cysts in the presence of cirrhosis, portal vein thrombosis, and hepatocellular carcinoma. This confirms the previously noted association of cysts and portal vein thrombosis. The possibility of obstruction caused by benign cysts should be considered when investigating patients with intrahepatic bile duct obstruction.     

Intrahepatic cholestatic jaundice related to administration of ranitidine. A case report with histologic and ultramicroscopic study

Ranitidine may cause liver injuries ranging from transient, subclinical serum transaminases increase every 100-1,000 treated patients to cholestatic hepatitis in less than 1/100,000. Other H2-receptor antagonists are more dangerous: 11 toxic hepatitis cases have been reported as adverse effect after 1 year of marketed ebrotidine. A 75-year-old male with ischemic cardiopathy history was started on an 8 days treatment of oral ranitidine due to pirosis, without any other changes of therapy; 48 h after drug withdrawal, light-coloured stools, dark urine and icteric scleras developed. On hospital admission, 10 days later, physical examination showed slight hepatomegaly and severe jaundice with skin excoriations followed by serum mixed bilirubin further increase and aminotransferases activities mild rise. Total bilirubin peaked at 381.33 mmol/l (5.1-17.1) and progressively returned to normal, after discharge home, in 3 months and now, 1 year later, there is no sign of liver disease. Ultrasonographic biliary anomalies and the most frequent causes of liver damage were excluded. Liver biopsy confirmed ranitidine as the most likely cause of liver toxicity since histological and ultramicroscopical study revealed a drug-induced picture. We report a rare case of intrahepatic cholestasis jaundice related to ranitidine, a widely used drug. Diagnosis would need an ethically unacceptable rechallange test.     

Lyme disease presenting as infarction pain. A case report

Lyme's disease is a multi-system condition due to infection with a spirochete (Borrelia Burgdorferi), transmitted by a tick. Cardiac involvement, which is not systematic, usually presents with transient atrioventricular block of varying degree. The authors describe an unusual presentation of the cardiac involvement of Lyme's disease with chest pain resembling an acute coronary syndrome in a 32 year old man. The characteristic skin lesion (erythema migrans), the positivity of IgM serology, the myocardial scintigraphic results and the negativity of the work-up of other causes of this pain led to a diagnosis of myocarditis, the outcome of which was favourable with treatment by amoxycillin (3 g/day, orally).     

Hepatic tuberculomas. A case report

BACKGROUND: The liver is often involved secondarily by sytemic/extrahepatic vascular, metabolic, infectious, granulomatous, and malignant processes. CASE REPORT: A 57-year old woman was admitted because of fatigue, malaise, night sweating and right upper abdominal quadrant pain. Physical findings revealed pale skin and mucosae, and hepatomegaly. Laboratory data showed normocytic, normochromic anemia and marked inflammatory syndrome. Real-time ultrasonography revealed one hypo-echogenic nodule, 25 mm in size, in the segment II of the liver, and three hypoechogenic nodules, 11-25 mm in diameter, in segments III and IV. Enlarged lymph nodes, 20-50 mm, were observed in the region of the pancreatic head. Histo-pathological examination of the liver and peritoneum biopsies evidenced granulomas with caseous necrosis and multinuclear Langhans' giant cells, indicating hepatic and peritoneal tuberculosis. The tuberculostatic chemotherapy (isoniazid 300 mg/24h; rifampycin 600 mg/24h and pyrazinamid 2000 mg/24h) was applied for 12 months. The patient responded well to the treatment, followed-up for 6-12 months. CONCLUSION: In the differential diagnosis of focal liver lesions, pseudotumoral hepatic tuberculomas must be considered.     

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.     

Hepatic tuberculosis: case report of pseudotumoral form

Inflammatory pseudo-tumors of the liver are rare and difficult to diagnose, mimicking malignant tumors. We report a patient, 42 year old with hepatic pseudo-tumor who was suspected to have pseudotumoral hepatic tuberculosis without immunodepression and treated by major hepatic surgery because no sure diagnosis. Therapeutic approach of hepatic inflammatory pseudotumors is often medical and surgical and may need major hepatic surgery in case of sure etiologic diagnosis.
