1/21. Hepatobiliary dysfunction as the initial manifestation of disseminated cryptococcosis.A case of hepatobiliary dysfunction as the initial manifestation of disseminated cryptococcosis is described. The patient was admitted with symptoms of hepatitis with cholestatic jaundice. Antibody tests for hepatitis b and C and human immunodeficiency virus were negative. The patient continued to deteriorate clinically. Eventually, the patient succumbed to hepatic failure. autopsy disclosed systemic cryptococcosis that caused extensive necrosis of the liver. In review of the literature, only nine cases of cryptococcal infection presenting as hepatitis, cholangitis, and cholecystitis as initial manifestation were reported. Four of these patients had been subjected to exploratory laparotomy for clinical suspicion of acute abdomen. One patient developed cirrhosis as a result of cryptococcal hepatitis. Two patients succumbed to hepatic failure. cryptococcosis is known to occur commonly in immunocompromised patients, yet only two reported cases presenting as hepatitis were associated with immunocompromised status.- - - - - - - - - - ranking = 1keywords = immunodeficiency (Clic here for more details about this article) |
2/21. Polymicrobial cholangitis and liver abscess in a patient with the acquired immunodeficiency syndrome.cholangitis/cholangiopathy associated with the human immunodeficiency virus (hiv) infection is characterized by chronic abdominal pain, low-grade fever, cholestasis, and sometimes areas of focal or diffuse dilatation of the bile ducts that may be apparent on noninvasive imaging studies. Although the etiology of this biliary disease may be multifactorial, it appears to be the result of immunosuppression and/or secondary opportunistic infections rather than a direct cytopathic effect of hiv itself. Various opportunistic pathogens, including cytomegalovirus, cryptosporidium, campylobacter fetus, and candida albicans, have been implicated as causes of hiv-associated cholangitis. We report an unusual case of polymicrobial cholangitis and liver abscess in a patient with hiv infection.- - - - - - - - - - ranking = 29.055343193566keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |
3/21. Biliary giardiasis in a patient with human immunodeficiency virus.A 41-year-old man with human immunodeficiency virus (hiv) (CD4 count, 446/mm3) developed a protracted course of abdominal pain, weight loss, and increasing liver function tests after undergoing a metronidazole treatment regimen for Giardia enteritis. Three months later, endoscopic retrograde cholangiography (ERCP) showed dilated common and intrahepatic bile ducts and luminal irregularities of the common bile duct. Seven months after the onset of his acute diarrhea, a repeat ERCP with aspiration demonstrated many Giardia trophozoites and cysts in the bile and continued structural abnormalities consistent with cholangiopathy. A 10-day course of high-dose intravenous metronidazole did not resolve these signs or symptoms. A gallbladder ultrasound showed a thickened wall. Laparoscopic cholecystectomy led to resolution of abdominal pain and normalization of serum alkaline phosphatase over an 8-month period. gallbladder histopathology revealed chronic cholecystitis, but no parasites were seen on hematoxylin and eosin staining or with Giardia antigen enzyme immunoassay testing of the gallbladder. The patient refused to undergo a follow-up ERCP, but a right upper quadrant ultrasound and computed tomography of the abdomen were normal.- - - - - - - - - - ranking = 5keywords = immunodeficiency (Clic here for more details about this article) |
4/21. Adenovirus ascending cholangiohepatitis.Three children, two with liver transplants and one with acquired human immunodeficiency virus (hiv) infection, presented with hepatitis accompanied by elevated gamma glutamyl transpeptidase. Biopsies revealed cholangiohepatitis caused by adenovirus infection. There was a progressive loss of interlobular bile ducts in two of the patients. In one patient, infection of the biliary tree was marked by a necrotizing cholangitis, with adenoviral inclusions noted in the biliary epithelium. In each patient, there was evidence of adenovirus gastrointestinal infection. This is the first report of adenoviral infection of the biliary tree in humans. It is hypothesized that adenovirus cholangiohepatitis occurs as a result of ascending infection from the gastrointestinal tract to the biliary tree.- - - - - - - - - - ranking = 1keywords = immunodeficiency (Clic here for more details about this article) |
5/21. Molecular characterization of a novel splice site mutation within the CYBB gene leading to X-linked chronic granulomatous disease.Chronic granulomatous disease (CGD) is a primary immunodeficiency that affects the oxidative mechanism of microbial killing of phagocytic cells. The defect is characterized by a lack or severely reduced superoxide anion (O2-) production by phagocytes. Seventy percent of CGD cases are X-linked (X-CGD) and they are caused by mutations in the gene encoding for gp91(phox), one of the two subunits of the flavocytochrome b558 of the nadph oxidase. We identified an abnormal transcript arising from a novel splice site mutation within the gene encoding gp91(phox), which suggested that the mutation affected normal mRNA splicing. Thus, the effect of this mutation leads to the complete absence of the flavocytochrome b558 in neutrophil membranes, which caused the biochemical phenotype X91 degrees-CGD in this family. These molecular findings help to explain the early onset and severe phenotype in this X-CGD kindred.- - - - - - - - - - ranking = 1keywords = immunodeficiency (Clic here for more details about this article) |
6/21. Percutaneous transhepatic cholangiography. Problems in interpretation.The patient who presents with jaundice, regardless of the etiology, cannot be adequately examined by a gallbladder series and intravenous cholangiography. Clinical evaluation aided by laboratory analysis will not always differentiate between primary liver parenchymal disease and biliary tract obstruction. Percutaneous transhepatic cholangiography, when successfully performed, answers the question of whether the jaundice is due to primary liver parenchymal disease or due to biliary tract obstruction. The point to emphasize is that under no circumstances is it appropriate to presume any information if the biliary system is not entered and visualized successfully. The proper interpretation of the level of block can fall prey to the mistake of incomplete aspiration of the thick, inspissated bile in the obstructed biliary tree before injection of contrast material. The problem will be worsened by a peripheral entrance into the biliary system rather than a more central one. Gastrointestinal series should always be available to aid in identifying pathology at the entrace of the common bile duct into the duodenum. Lastly, identifying the etiology at the site of the block will require additional procedures. Selective visceral angiography has contributed greatly in this area. During the 20 years of clinical usage of percutaneous transhepatic cholangiography, we feel it has become the single examination capable of preventing unnecessary exploration of the jaundiced patient with primary liver parenchymal disease and the most useful potential source of practical information if laparotomy is necessary to correct biliary tract obstruction.- - - - - - - - - - ranking = 0.13312148546463keywords = aid (Clic here for more details about this article) |
7/21. Hepatobiliary cryptosporidiosis and cytomegalovirus infection mimicking metastatic cancer to the liver.A cholestatic syndrome caused by sclerosing cholangitis and papillary stenosis has been described in patients with the acquired immunodeficiency syndrome and hepatobiliary cryptosporidiosis and cytomegalovirus infection. The case of a 41-year-old homosexual man with the acquired immunodeficiency syndrome who presented with abdominal pain, diarrhea, fever, and cholestasis is reported. A percutaneous transhepatic cholangiogram showed that the extrahepatic and right-sided intrahepatic ducts were normal. Computerized tomography of the abdomen showed multiple hypodense lesions in the liver. Guided needle biopsies of several of these lesions showed severe confluent necrotizing pericholangitis with cytomegalovirus-infected cells. Numerous cryptosporidia were seen attached to biliary epithelium. The unique histopathologic and radiographic features of this case should be added to the spectrum of hepatobiliary manifestations of the acquired immunodeficiency syndrome.- - - - - - - - - - ranking = 21.041507395175keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |
8/21. cholangitis associated with cholecystitis in patients with acquired immunodeficiency syndrome.Four patients with acquired immunodeficiency syndrome developed severe abdominal pain and fever due to acute acalculous cholecystitis. In all patients, preoperative laboratory data showed elevation of alkaline phosphatase and gamma-glutamyltransferase levels. Endoscopic or intraoperative cholangiography showed signs of intrahepatic and extrahepatic cholangitis. cholecystectomy was performed and prompt relief of symptoms was achieved in all patients; no postoperative complication was observed. One patient did not develop any recurrence during an 18-month period of follow-up; two patients died 2 and 3 months after the operation. One patient developed recurrent abdominal pain and cholestasis 4 months after the operation, with dilatation of the common bile duct and papillary stenosis due to progression of cholangitis. These observations suggest that cholangitis is frequently associated with cholecystitis in patients with the acquired immunodeficiency syndrome. Its pathogenesis is not known.- - - - - - - - - - ranking = 42.083014790349keywords = immunodeficiency syndrome, immunodeficiency (Clic here for more details about this article) |
9/21. Sclerosing cholangitis after continuous hepatic artery infusion of FUDR.Eight of 46 (17.4%) patients treated in our trial of continuous hepatic artery infusion (CHAI) of fluorodeoxyuridine (FUDR) by Infusaid pump developed biliary strictures. The lesions were clinically, radiographically, and pathologically identical to the idiopathic sclerosing cholangitis frequently seen in association with inflammatory bowel disease. Treatment included immediate cessation of intraarterial FUDR, and surgical or percutaneous drainage of the biliary tree if it was dilated. Two of the eight patients died of the complication. Three patients stabilized after biliary system drainage, and two patients improved on observation only. The pathogenesis of this complication is not understood. This report details the clinical and pathological features of this entity.- - - - - - - - - - ranking = 0.066560742732315keywords = aid (Clic here for more details about this article) |
