Hyperthyroidism in two patients with Crohn disease and Takayasu arteritis.

Thyroid abnormalities and Takayasu arteritis (TA) have been reported separately in patients with Crohn disease (CD). We report two patients with hyperthyroidism, CD and Takayasu arteritis and discuss hypothetical mechanisms. Case 1. A thyrotoxic goiter was diagnosed in 1987 in a 34-year-old woman treated since 1969 for severe CD and TA. Iodine urinary excretion was 405 microg/mL (20-500). Anti-thyrotropin receptor (TRAK) and anti-thyroid antibodies were not detectable. The ultrasonography showed a nodule in the right lobe of the thyroid and two nodules in the left lobe. A 123I thyroid scan showed a multinodular goiter with no hot nodule. She was treated successfully with propylthiouracile until 1991, when a new episode of thyrotoxicosis led to a subtotal thyroidectomy. Case 2. Hyperthyroidism was diagnosed in February 2000 in a 49-year-old woman treated for CD and TA, both diagnosed in 1980. TRAK and anti-thyroid peroxydase antibodies were not detectable. The ultrasonography disclosed a normal thyroid volume with an inhomogeneous parenchymal structure and nodular images in both lobes. A 123I thyroid scan showed one hot nodule in the lower part of each lobe. A subtotal thyroidectomy was performed. The association of these three diseases may not be fortuitous, possibly explained by genetic predisposing factors and disease-related iodine deficiency both involving Nuclear Factor kappaB pathway.

Bacterial meningitis in cirrhosis: review of 16 cases.

BACKGROUND: Although bacterial infections are frequent in patients with liver cirrhosis, only isolated cases of bacterial meningitis have been reported. METHODS: We have reviewed a series of 16 cases of bacterial meningitis in patients with cirrhosis, diagnosed in a single hospital over a 30-year period. RESULTS: Thirteen patients had alcoholic cirrhosis. On presentation, all patients had fever and most of them had an abnormal mental status (coma in 11 cases), but neck stiffness was not present or was delayed for more than 24 h in seven (43.7%) patients. The cerebrospinal fluid white cell count was always elevated, higher than 1000/microl in ten cases. The cerebrospinal fluid culture was positive in 14 (87.5%) patients. Gram-negative bacilli (mainly E. coli) and L. monocytogenes were the most frequent pathogens, accounting for nine cases. In contrast, S. pneumoniae and N. meningitidis were found in only four cases. Concurrent bacteremia was present in 12 (75%) cases. Ten patients (62.5%) died. Death was meningitis-related in seven patients and due to decompensated liver cirrhosis after clinical recovery from meningitis in the three other patients. Child-Pugh class C was associated with a higher mortality rate (80%, versus 33% for Child-Pugh class A-B), although the difference did not reach statistical significance. CONCLUSIONS: Bacterial meningitis should be suspected in every patient with cirrhosis presenting with a febrile coma. If lumbar puncture must be delayed, or if no causative agent can be identified on cerebrospinal Gram stain despite elevated cerebrospinal fluid white cell count, empirical antimicrobial therapy should be started straightaway with ampicillin plus a third-generation cephalosporin in sufficient doses.

Systemic antibiotic prophylaxis after gastrointestinal hemorrhage in cirrhotic patients with a high risk of infection.

In cirrhotic patients with gastrointestinal hemorrhage, bacterial infections are frequent and play a significant role in mortality. We have previously found that patients with a Child-Pugh's class C or a rebleeding are a subgroup of cirrhotic patients with a high risk of infection. The aims of the study were (1) to validate these indicators and (2) to assess the effectiveness of a systemic antibiotic treatment in preventing bacterial infections in bleeding cirrhotics with a high risk of infection. One hundred and nineteen bleeding cirrhotic patients were divided into 3 groups. Patients with a Child-Pugh's class A-B and no rebleeding (i.e., with a low risk of infection) constituted group 1 (n = 55). Patients with a high risk of infection were randomly allocated to serve as controls (group 2, n = 34) or to receive the ciprofloxacin and a combination of amoxicillin and clavulanic acid for 3 days after hemorrhage (group 3, n = 30). This antibiotic prophylaxis was administered first intravenously and then orally when the bleeding was controlled. The study period was defined as 10 days after hemorrhage. Incidence of bacterial infections was significantly higher in patients from group 2 than in patients from group 1 (52.9% vs. 18.2%; P < .001). Moreover, infections were more severe in group 2: a sepsis syndrome or a septic shock developed in 66.7% of infected patients from this group, but in only 20% of infected patients from group 1. Incidence of bacterial infections was much lower in patients from group 3 than in those from group 2 (13.3% vs. 52.9%; P < .001). Eight patients from group 2 (23.5%) and 4 patients from group 3 (13.3%) died during the first four weeks (P-not significant). Septic shock was the cause of death in 3 patients from group 2 and in only 1 patient from group 3. The cost of antibiotic therapy, including antibiotic prophylaxis in group 3, was $208 +/- $63 per patient in group 2 and $167 +/- $42 per patient in group 3 (P < .05). We conclude that (1) patients with a Child-Pugh's class C and/or a rebleeding are a subgroup of cirrhotic patients with a high risk of infection after gastrointestinal hemorrhage and that (2) in these patients, a prophylactic treatment with systemic antibiotics is very effective in preventing bacterial infections.

[Prognostic indicators in patients with liver cirrhosis admitted to an intensive care unit]. / Indicateurs pronostiques chez les malades atteints de cirrhose admis en service de Réanimation.

OBJECTIVES: Assessment of prognosis in patients with cirrhosis admitted to an Intensive Care Unit remains unsatisfactory. The aims of this retrospective study were to determine the survival rates of patients admitted to an Intensive Care Unit, and to identify and validate prognostic indicators associated with a high mortality rate. METHODS: Two hundred and forty three patients with cirrhosis consecutively admitted to the Intensive Care Unit were studied. The main reasons for admission were upper gastrointestinal bleeding (n = 163), coma (n = 43), sepsis (n = 18), and liver failure (n = 13). Patients were divided into two groups: group 1 (n = 121) to identify prognostic indicators associated with a high mortality rate, and group 2 (n = 122) to validate these indicators. RESULTS: Intensive Care Unit and one year survival rates of patients with cirrhosis admitted for upper gastrointestinal hemorrhage were 76 and 50% respectively. These rates were 40 and 8% respectively for patients admitted for other reasons. In group 1, 4 predictive factors found at admission were identified to have independent significance by stepwise logistic regression: grade III or IV encephalopathy, prothrombin index, serum creatinine, and hypoxemia. On the other hand, the presence of shock on admission was associated with a 100% mortality rate. Two prognostic indicators were defined: shock requiring the administration of vasoactive drugs, and the presence of 3 out of the 4 following predictive factors: grade III or IV encephalopathy, mechanical ventilation, prothrombin index < 30%, and serum creatinine > 130 mumol/L. In group 2, the presence of at least one prognostic indicator at admission or during intensive care was associated with a 96% mortality rate. These indicators were present in 69% of patients who died. In 17 patients who died, but survived more than 24 hours in the Intensive Care Unit, indicators were present an average of 6.0 +/- 5.3 days before death. CONCLUSION: Common prognostic indicators may accurately predict death in patients with cirrhosis admitted to an Intensive Care Unit. These indicators could be helpful in identifying patients who will not benefit from intensive care.

[Gastric protein loss and alcoholic cirrhosis. Study by measurement of gastric clearance of alpha 1-antitrypsin]. / Pertes protéiques gastriques et cirrhose alcoolique. Etude par la mesure de la clairance gastrique de l' alpha 1-antitrypsine.

OBJECTIVE: The aim of the study was to assess gastric protein loss in alcoholic cirrhotic patients, and to determine its role in the low serum albumin levels frequently observed in these patients. METHODS: Twenty-six alcoholic cirrhotic patients with ascites and serum albumin levels < 30 g/L were studied and compared to 6 healthy volunteers. Gastric protein loss was determined by measuring gastric clearance of alpha 1-antitrypsin. RESULTS: Gastric clearance of alpha 1-antitrypsin was 0.96 +/- 1.42 mL/h (median : 0.52; range: 0.11-6.54) in cirrhotic patients and 0.48 +/- 0.20 mL/h (median: 0.51) in healthy volunteers. Values in cirrhotic patients were not significantly different from healthy volunteers. However, 3 cirrhotic patients had high values of gastric clearance of alpha 1-antitrypsin (2.84, 3.99 and 6.54 mL/h). Their serum albumin and protein levels were significantly lower than those in the 23 other patients (P < 0.05 and < 0.03, respectively). Severe portal hypertensive gastropathy was present in two out of these 3 patients and in two out of the 23 other patients. CONCLUSION: Gastric protein loss is not significantly increased in liver cirrhosis. However, in a few patients, this loss is high and may play a role in low serum albumin levels.

Liver disease from surreptitious administration of urethane.

We report subacute necrosis, peliosis hepatis, venoocclusive disease and hepatic angiosarcoma after long-term administration of urethane. We take this to be the 12th case of urethane-induced hepatitis and the first associated with vascular liver tumor.

Emergency liver transplantation for acute liver failure. Evaluation of London and Clichy criteria.

Two sets of prognostic indicators were recently proposed for selection of patients with acute liver failure for emergency liver transplantation. According to the London criteria, patients with non-paracetamol-induced acute liver failure should be referred for liver transplantation when the prothrombin time is > 100 s or when any three of the following prognostic indicators are present: age < 10 or > 40 yr; non-A, non-B hepatitis, halothane hepatitis or idiosyncratic drug reaction; duration of jaundice before onset of encephalopathy > 7 days; prothrombin time > 50 s; serum bilirubin > 300 mumol/l. According to the Clichy criteria, in acute viral hepatitis, liver transplantation should be decided in patients with coma or confusion, and Factor V < 20% (age < 30 yr) or < 30% (age > 30 yr). To assess the accuracy of these criteria, 81 non-transplanted patients with non-paracetamol-induced acute liver failure were retrospectively studied. The mortality rate was 0.81. The predictive accuracies, respectively on admission and 48 h before death, were 0.80 and 0.79 for the London criteria, and 0.60 and 0.73 for the Clichy criteria. The positive and negative predictive values, 48 h before death, were 0.89 and 0.47 for the London criteria, and 0.89 and 0.36 for the Clichy criteria, respectively. In the 49 patients with acute viral liver failure, the results of the Clichy criteria were similar. In a subgroup of 24 patients who had not received either fresh frozen plasma or sedative-hypnotic drug, the positive predictive values were equal to 1 for the two sets of prognostic indicators, but the predictive accuracies only slightly increased.(ABSTRACT TRUNCATED AT 250 WORDS)

Low early gallstone recurrence rate after successful extracorporeal lithotripsy in patients with solitary stones.

Piezoelectric lithotripsy with the EDAP LT-01 machine combined with adjuvant bile acid therapy results in complete clearance of radiolucent gallstones in selected patients. We assessed stone recurrence rate in 84 patients with complete clearance of stone fragments and followed up at least 12 months after cessation of bile acid therapy (mean 17 months, range 12-33). Fifty-four patients had a solitary stone and 30 multiple stones. Bile acid therapy was continued for 3 months after complete fragment stones clearance which was ascertained by two consecutive ultrasound examinations. Stone recurrence was assessed by ultrasonography at 6 and 12 months, and then at least once a year. Gallstone recurrence occurred in 5 patients (6%) between 9 and 12 months with no further recurrence up to 33 months. The rate of recurrence at one year was 3.7% in patients with a solitary stone and 10% in patients with multiple stones. Only one patient with stone recurrence had recurrent biliary pain. We concluded that early gallstone recurrence rate after successful lithotripsy seems to be low in patients with solitary stones.
