[Incidence of cardiovascular events in giant cell arteritis: preliminary results of a prospective double cohort study (GRACG)].

UNLABELLED: Giant cell arteritis is the most frequent vasculitis. Cardiovascular events such as cerebrovascular accident or ischemic heart disease may occur in patients with giant cell arteritis. However, their real incidence, as well as their relative risk compared to the general population, remains unknown. PURPOSE: To assess in a prospective, double cohort study, the incidence of cardiovascular events in giant cell arteritis patients compared to controls, after controlling for cardiovascular risk factors. PATIENTS AND METHODS: We included on predefined criteria 432 newly diagnosed patients with giant cell arteritis, each assigned to sex- and age-matched controls randomly selected from the general population. Cardiovascular risk factors (high-blood pressure, diabetes, smoking, hypercholesterolemia and preexisting peripheral vascular disease) were collected at inclusion. During the 24-month follow-up, all cardiovascular events were collected. After stratification for cardiovascular risk factors, a log-rank test was performed to compare cases and controls. A parametric survival model was used for multivariate analysis. RESULTS: Cardiovascular events all combined were significantly increased in patients with giant cell arteritis (RR = 2.15 [1.21-3.81], P = 0.009), and were mainly associated with age (P = 0.0001), past history of cardiovascular disease (P = 0.023) but also with giant cell arteritis (P = 0.009). However, each subset of cerebrovascular accident (RR = 2.42 [0.84-7]) or ischemic heart disease (RR = 1.67 [0.72-3.89]) increased but did not significantly. CONCLUSION: Cardiovascular events incidence is increased in patients with giant cell arteritis, and prescription of preventive antiagregant treatment may be discussed.

[Aetiological spectrum of hyperferritinemia].

UNLABELLED: Serum ferritin levels may be increased in many conditions: renal diseases, liver diseases, human immunodeficiency virus infection. The purpose of this study was to assess the aetiological spectrum of high serum ferritin levels in a 1200-bed university hospital, to compare our results with the data already published and to assess a potential association between aetiology and ferritin levels. PATIENTS AND METHODS: Patients with a serum ferritin level higher than 600 microg/l were retrospectively included between 15 November 2003 and 15 January 2004, and their medical records were reviewed. RESULTS: Ninety-eight patients (38 women and 60 men; median age: 59,5 years [19-92]) were recruited in departments of hepatology and gastroenterology (22%), haematology (14%) and internal medicine (18%). Diagnosis performed were: non-HIV systemic infections (23,8%), haematological diseases (16,1%), alcoholism (11,2%) and malignancies (9,8%). Dialysed chronic renal failure, liver diseases, haemochromatosis and systemic inflammatory diseases counted for 4.2 to 5.2% of cases. Serum ferritin level lied between 600 and 1000 microg/l for 50 patients, between 1000 and 1500 microg/l for 24, and over 1500 microg/l for 24. There was no significant difference between the three groups as regards the etiological distribution. DISCUSSION: In our study, chronic renal failure was not a major cause of high ferritin level: this is probably due to the current use of erythropoietin, which has decreased the use of blood transfusions. The two major aetiology of hyperferritinemia were non-HIV infections and malignancies.

[Angioedema and angiotensin converting enzyme inhibitors: a report of 19 cases].

PURPOSE: Inhibitors of angiotensin-converting enzyme are worldwide used and are a real progress for the treatment of systemic hypertension or cardiac failure and are a real progress. The most common adverse side effect is cough. Angioedema is a sudden and localized edema involving the deeper cutaneous and mucosa tissue lappers. 0.1-0.5% of patients treated by ACE inhibitors could develop angioedema. MATERIALS AND METHODS: We report a series of 19 cases, recruited in the Parmacovigilance Center of the University Hospital of Amiens from 1997 to 2003. RESULTS: All the patients had a facial swelling edema at initial presentation. Intestinal mucosa or preputial are misleading localisations. In 1/3 of cases, angioedema appeared after the first administration, in 1/3 of cases it appeared with a delay of 1-2 years. The oropharynx localisation with glottic involvement may need an airway intervention. One patient died from pulmonary distress at home. CONCLUSION: The pathophysiology is current unknown although there is increasing evidence for bradykinin accumulation involvement. The treatment by ACE inhibitors must be broken off; angiotensin II antagonists may be an alternative treatment, but has to be introduced carefully.

[The technique of Trans-Jugular Porto-systemic Shunt (TIPS)].

The placement of a Trans Jugular Portosystemic Shunt (TIPS) demands a precise and rigorous surgical technique. The steps for insertion are: 1) Puncture of the right internal jugular vein with ultrasound guidance; 2) Selective catheterization of the right hepatic vein; 3) Transparenchymal direction of the catheter into a branch of the right portal vein; 4) Dilation of the parenchymal tract; 5) Deployment of an expanding metallic veno-venous shunt. Post-operative care and the most common complications are discussed.

[Fistulisation of a tubercular adenopathy in the oesophagus. About a paucisymptomatic form].

The authors present the case of a cervico-mediastinal mass which disappeared spontaneously. The clinical presentation and the image of a fistula during the oesophagoscopy are in favour of the fistulisation of a tubercular adenopathy in the oesophagus. This pathology is rare. This observation is original by the delay of diagnosis due to a dysphagie summarizing the clinical signs and the spontaneously favorable evolution of the fistula.

Salvage transjugular intrahepatic portosystemic shunt for uncontrolled variceal bleeding in patients with decompensated cirrhosis.

BACKGROUND/AIMS: The place of transjugular intrahepatic porto-systemic shunt (TIPS) for variceal haemorrhage uncontrolled by sclerotherapy and medical treatment is still undefined. To investigate the outcome of early salvage TIPS for active uncontrolled variceal haemorrhage, and to identify the factors associated with mortality. METHODS: Salvage TIPS was performed in 58 patients as soon as possible after the diagnosis of variceal bleeding refractory to the combination of sclerotherapy and of pharmacological therapy. Twenty-three variables were assessed prospectively to identify predictors of mortality within 60 days of the procedure. RESULTS: The haemorrhage was controlled in 52 of 58 patients (90%). Bleeding persisted in six of 58 patients (10%), and recurred in four patients (7%). Overall, 17 (29%) and 20 (35%) patients died within respectively 30 days and 60 days of TIPS: five patients died of persistent bleeding, two patients died of recurrent bleeding, and 13 patients died of terminal liver failure. The actuarial survival following salvage TIPS was 51.7% at 1 year. On multivariate analysis, independent predictors of early mortality were: the presence of sepsis (P=0.001), the use of catecholamines for systemic hemodynamic impairment (P=0.009), and the use of balloon tamponade (P=0.04). Neither a single factor, nor a combination of factors before TIPS allowed to predict mortality confidently in a given patient. CONCLUSIONS: Early salvage TIPS is an effective treatment to stop active variceal bleeding refractory to sclerotherapy and pharmacological treatment. Pre-treatment prognostic determinants that correlate to mortality can not be used to predict the outcome in individual cases.

Neoadjuvant transjugular intrahepatic portosystemic shunt: a solution for extrahepatic abdominal operation in cirrhotic patients with severe portal hypertension.

BACKGROUND: Major abdominal surgery, although technically feasible per se, can be contraindicated in some cirrhotic patients because of severe portal hypertension. The present study reports our experience of seven such patients who were prepared for major abdominal surgery by transjugular intrahepatic portosystemic shunt (TIPS). STUDY DESIGN: There were seven cirrhotic patients (six men and one woman aged 47 to 69 years) with portal hypertension. Portal hypertension was considered severe because of the presence of at least one of the following: history of variceal bleeding (five of seven patients), varices at risk of bleeding (red signs or cardial location of varices; four of seven patients), or intractable ascites (three of seven patients). The planned operations included colon, gastroesophageal, kidney, and aortic procedures in three, two, one, and one patient, respectively. Because portal hypertension was the leading cause of surgical contraindication, the following "two-step strategy" was applied to the seven patients: first, TIPS to control portal hypertension, followed, after a delay of at least 1 month, by abdominal surgery. RESULTS: The TIPS procedure was successfully performed in all patients without complications. The hepatic venous pressure gradient decreased from 18+/-5 to 9+/-5 mm Hg (p<0.01). All patients were operated on with a delay ranging from 1 month to 5 months after TIPS (2.9+/-1.3 months; median 3 months). The planned operation was performed in six of the seven patients. One patient with cancer of the cardia did not have resection because of extensive abdominal spreading of the tumor. Intraoperative transfusion was necessary in only two patients. Operative mortality occurred in one patient, 36 days after resection of a left colon cancer. CONCLUSIONS: The minimally invasive nature of TIPS allows us to propose the following two-step management of cirrhotic patients with severe portal hypertension needing abdominal surgery: decompression of the portal system by TIPS followed by elective surgery.

Auxiliary partial orthotopic versus standard orthotopic whole liver transplantation for acute liver failure: a reappraisal from a single center by a case-control study.

OBJECTIVE: To reappraise the results of auxiliary partial orthotopic liver transplantation (APOLT) compared with those of standard whole-liver transplantation (OLT) in terms of postoperative death and complications, including neurologic sequelae. SUMMARY BACKGROUND DATA: Compared with OLT, APOLT preserves the possibility for the native liver to recover, and to stop immunosuppression. METHODS: In a consecutive series of 49 patients transplanted for fulminant or subfulminant hepatitis, 37 received OLT and 12 received APOLT. APOLT was done when logistics allowed simultaneous performance of graft preparation and the native liver partial hepatectomy to revascularize the graft as soon as possible. Each patient undergoing APOLT (12 patients) was matched to two patients undergoing OLT (24 patients) according to age, grade of coma, etiology, and fulminant or subfulminant type of hepatitis. All grafts in the study population were retrieved from optimal donors. RESULTS: Before surgery, both groups were comparable in all aspects. In-hospital death occurred in 4 of 12 patients undergoing APOLT compared with 6 of 24 patients undergoing OLT. Patients receiving APOLT had 1 +/- 1.3 technical complications compared with 0.3 +/- 0.5 for OLT patients. Bacteriemia was significantly more frequent after APOLT than after OLT. The need for retransplantation was significantly higher in the APOLT patients (3/12 vs. 0/24). Brain death from brain edema or neurologic sequelae was significantly more frequent after APOLT (4/12 vs. 2/24). One-year patient survival was comparable in both groups (66% vs. 66%), and there was a trend toward lower 1-year retransplantation-free survival rates in the APOLT group (39% vs. 66%). Only 2 of 12 (17%) patients had full success with APOLT (i.e., patient survival, liver regeneration, withdrawal of immunosuppression, and graft removal). One of these two patients had neurologic sequelae. CONCLUSIONS: Using optimal grafts, APOLT and OLT have similar patient survival rates. However, the complication rate is higher with APOLT. On an intent-to-treat basis, the efficacy of the APOLT procedure is low. This analysis suggests that the indications for an APOLT procedure should be reconsidered in the light of the risks of technical complications and neurologic sequelae.
