A French national survey on the use of antibiotic prophylaxis in cirrhotic patients.

BACKGROUND: Guidelines recommend antibiotic prophylaxis (AP) in well-selected groups of cirrhotic patients, but the impact of these recommendations has not been assessed in France. AIM: To evaluate AP prescription tendencies for gastrointestinal bleeding, and primary and secondary prophylaxis of spontaneous bacterial peritonitis (SBP). METHODS: Practitioners (n = 1,159) working in general hospitals (GH) or in university hospitals (UH) received a self-administered questionnaire. RESULTS: Three hundred and eighty-nine (33.6%; GH 35% and UH 30.4%) practitioners responded. AP was prescribed by 97.7%, 72.3% and 94.8% of practitioners, without significant differences between UH and GH, respectively, for gastrointestinal bleeding (quinolones 48.2%, third-generation cephalosporins 27.7% and amoxicillin-clavulanic acid 22.2%), primary (quinolones 97.2%) and secondary prophylaxis of SBP (quinolones 99%). For gastrointestinal bleeding, ofloxacin (47.6%) and norfloxacin (37.4%) were the main quinolones prescribed, and ceftriaxone (77%) was the main third-generation cephalosporin prescribed. The principal reasons for prescribing AP were a decrease in bacterial infection (88.9% for gastrointestinal bleeding, 91.3% for primary and 94.3% for secondary prophylaxis of SBP), a recommendation by a consensus conference (83%, 38% and 74.4% respectively) and an improvement in survival (72.8%, 41.3% and 57.7% respectively). Only 31.7% of practitioners (39.6% for UH vs. 28.6% for GH; P = 0.038) believed that AP may reduce the risk of bleeding recurrence. Reported side effects (28%) of AP mainly concerned the risk of quinolone resistance (62% of cases). CONCLUSION: Antibiotic prophylaxis is well-recognized by French practitioners, but its routine use depends on the expertise of practitioners. Quinolones remain the main antibiotic class prescribed irrespective of the type of prophylaxis.

Spigelian hernia: CT findings and clinical relevance.

OBJECTIVE: The purpose of our study was to evaluate the clinical relevance of preoperative CT in distinguishing between the two subtypes of spigelian hernia (SH). MATERIALS AND METHODS: We reviewed retrospectively the CT images of 35 patients. The patients were divided into two groups on the basis of the SH subtype: interstitial SH group (n = 15) and subcutaneous SH group (n = 20). Clinical characteristics of patients and CT findings were analyzed. Bowel ischemia on surgery was also noted. RESULTS: Sixteen right hernias and 19 left hernias were observed. Fifteen interstitial SH (43%) and 20 subcutaneous SH (57%) were found. No type of content showed a statistically significant association with one or other subtype of SH. Nine of the 26 patients presenting with SH with SB content showed signs of SBO on CT. Closed-loop SBO on CT was present in 5 of the 26 patients with SB content. An interstitial SH was observed in all of these 5 patients (p = 0.039). Surgery was performed on 10 patients. Bowel ischemia was found on surgery in 4 patients and showed no statistically significant association with a particular subtype of SH (p = 0.6). CONCLUSION: Our study shows the importance of performing CT in SH. CT provides the diagnosis of SH, shows SH content, and demonstrates the presence of SBO or closed-loop SBO. Moreover, the distinction between the two subtypes of SH on CT appears to be of clinical relevance since closed-loop SBO is statistically associated with interstitial SH and the optimal surgical approach may differ.

Sentinel lymph node biopsy in melanoma: our 8-year clinical experience in a single French institute (2002-2009).

BACKGROUND: Since the introduction of sentinel lymph node biopsy (SLNB), its use as a standard of care for patients with clinically node-negative cutaneous melanoma remains controversial. We wished to evaluate our experience of SLNB for melanoma. METHODS: A single center observational cohort of 203 melanoma patients with a primary cutaneous melanoma (tumour thickness > 1 mm) and without clinical evidence of metastasis was investigated from 2002 to 2009. Head and neck melanoma were excluded. SLN was identified following preoperative lymphoscintigraphy and intraoperative gamma probe interrogation. RESULTS: The SLN identification rate was 97%. The SLN was tumor positive in 44 patients (22%). Positive SLN was significantly associated with primary tumor thickness and microscopic ulceration. The median follow-up was 39.5 (5-97) months. Disease progression was significantly more frequent in SLN positive patients (32% vs 13%, p = 0.002). Five-year DFS and OS of the entire cohort were 79.6% and 84.6%, respectively, with a statistical significant difference between SLN positive (58.7% and 69.7%) and SLN negative (85% and 90.3%) patients (p = 0.0006 and p = 0.0096 respectively). Postoperative complications after SLNB were observed in 12% of patients. CONCLUSION: Our data confirm previous studies and support the clinical usefulness of SLNB as a reliable and accurate staging method in patients with cutaneous melanoma. However, the benefit of additional CLND in patients with positive SLN remains to be demonstrated.

Emergency reversal of anticoagulation: the real use of prothrombin complex concentrates: a prospective multicenter two year French study from 2006 to 2008.

INTRODUCTION: Prothrombin complex concentrate (PCC) for reversal of vitamin K antagonist (VKA) is the main therapeutic option in cases of life-threatening bleeding. Clinical use of PCC is poorly documented. METHODS: We prospectively assessed PCC use in four French emergency departments during a two year period 2006-2008 before publication of French Guidelines. An appropriate treatment was defined when PCC was recommended, with a dose of PCC above or equal to 20 UI/kg, with vitamin K and with an assessment of international normalized ratio (INR) after PCC. Time of diagnosis and PCC administration were collected, as INR values, thromboembolic events within seven days, hospital mortality. RESULTS: 256 patients received PCC for reversal of OAT. PCC was mainly prescribed for major intracerebral (ICH) or gastrointestinal hemorrhage. An appropriate treatment was observed in 26% of patients. Intra-hospital mortality for major bleeding was 33% for ICH and 26% for non-ICH major bleeding. A PCC dose>20 UI/kg was able to reach an INR<1.5 in 65% of patients. For major hemorrhages (70%), time between patient arrival and treatment delivery exceeded three hours in half of cases. Control of INR was omitted in 20% of patients. No patients presented a thromboembolic event. CONCLUSION: A suitable treatment was administered in 26% of patients. A PCC dose of 20-30 IU/kg seems adequate in most cases to reverse VKA activity, but both higher and lower doses achieve similar effects. Considerable progress is required to improve PCC administration and control of treatment efficacy, and to shorten time to diagnosis.

High serum levels of free cortisol indicate severity of cirrhosis in hemodynamically stable patients.

BACKGROUND AND AIM: We investigated: (i) the association between severity of cirrhosis and serum levels of free cortisol (SFC) and total cortisol (STC), measured before and 30 min after (T(30)) the low-dose 1-µg short synacthen test (LD-SST); and (ii) the prognostic value of SFC and STC. METHODS: Consecutive, hemodynamically stable, cirrhotic patients (34 Child-Pugh class A, 29B, and 32C) underwent the LD-SST. Patients were followed for at least 12 months to assess non-transplant-related mortality. RESULTS: Child-Pugh class C patients had significantly higher basal levels of SFC than Child-Pugh class A or B patients. Prevalence of suspected adrenal dysfunction ranged between 7.4% (T(0) STC < 138 nmol/L) and 49.4% (change in STC < 250 nmol/L) according to the threshold used. In receiver-operator curve analysis, the area-under-the-curve values were 0.67 for T(30) SFC (0.51-0.79), 0.81 for Child-Pugh score (0.70-0.88), and 0.79 for albumin level (0.63-0.88). During the follow-up period, 16 patients with high T(30) SFC (≥ 78.9 nmol/L) (26.2%) and one patient with low T(30) SFC (< 78.9 nmol/L) (3.4%) died (P = 0.027 for high vs low T(30) SFC, log-rank test). Albeit not statistically significant, the risk of death for patients with T(30) SFC ≥ 78.9 nmol/L was fivefold higher than for patients with lower levels after adjusting for cirrhosis severity and level of albumin. CONCLUSIONS: One-year, non-transplant-related mortality is high among patients with T(30) levels of SFC ≥ 78.9 nmol/L (26.2%). These findings might result from latent inflammatory stress in hemodynamically stable cirrhotic patients, detected by adrenal testing.

C-reactive protein predicts short-term mortality in patients with cirrhosis.

BACKGROUND & AIMS: We aimed at improving prediction of short-term mortality in cirrhotic inpatients by evaluating C-reactive protein (CRP) as a surrogate marker of systemic inflammatory response syndrome (SIRS). METHODS: One-hundred and forty-eight consecutive cirrhotic patients with Child-Pugh score ≥ B8 and without hepatocellular carcinoma were prospectively included and followed for 182 days. The primary end point was 6-month survival. RESULTS: Main baseline characteristics were as follows: alcoholic liver disease in 88.5%; bacterial infection in 37%; hepatorenal syndrome in 7% of cases. CRP range was 1-240 mg/L (median 26 mg/L); 42 patients (28.4%) had SIRS as defined by ACCP/SCCM-criteria. CRP levels were higher in patients with SIRS (50 vs. 21 mg/L; p<0.0001), infection (46 vs. 27 mg/L; p<0.0001), and alcoholic hepatitis (44 vs. 32 mg/L, p=0.049). Forty-two patients died within the first 6 months of follow-up. Short-term mortality was associated with extrahepatic co-morbidities (p=0.002), high MELD score (p<0.001; AUROC=0.67), renal failure (p=0.008), elevated blood lactates (p<0.001), and high baseline CRP levels (p=0.003; AUROC=0.63; best cut-off value at 29 mg/L). Among patients with baseline CRP ≥ 29 mg/L, 32 still had CRP ≥ 29 mg/L at day 15 (group A). Group A was associated with 6-month mortality in the overall population (p<0.001) and also through sensitivity analyses restricted to patients without infection or alcoholic hepatitis. Multivariate analysis (Cox) adjusted for age identified three predictors of mortality: high MELD score (HR=1.08; 95% CI: 1.03-1.12; p<0.001), extrahepatic co-morbidities (HR=2.51; 95% CI: 1.31-4.84; p=0.006), and CRP level (group A) (HR=2.73; 95% CI: 1.41-5.26; p=0.003). The performance of the three variables taken together for predicting death was 0.80 (AUROC). CONCLUSIONS: In Child-Pugh score ≥ B8 cirrhotic patients, persistent CRP levels ≥ 29 mg/L predicted short-term mortality independently of age, MELD, and co-morbidities, and better than infection or clinically-assessed SIRS.

Response-guided peg-interferon plus ribavirin treatment duration in chronic hepatitis C: meta-analyses of randomized, controlled trials and implications for the future.

UNLABELLED: Response-guided pegylated interferon (peg-IFN) plus ribavirin (P/R) therapy trials on genotype (G)1 and G2/G3 hepatitis C virus-infected patients provide contradictory results. We conducted meta-analyses of randomized, controlled trials to address (1) the benefit of a 72-week extended-duration therapy in G1-slow responders and (2) adequate shortened duration therapy in G1 and G2/G3-rapid responders. Seventeen trials were selected, including 624 G1 rapid responders, 570 G1 slow responders, and 2,062 G2/G3 rapid responders. Virologic outcomes and treatment discontinuation data were collected from published articles and by asking investigators. Pooled estimates of sustained virologic response (SVR), relapse, and dropouts were calculated using the random effects model, considering the variability of shortened duration, ribavirin dose, genotype, and baseline viral load. In G1 slow responders, a 72-week extended duration increased SVR (+10.7%; 95% CI [confidence interval]: +4.4% to + 17.1%), decreased relapse (-12.3%; 95% CI: -25.4% to 0%), and did not significantly increase drop-out rates (+4.5%; 95% CI: -0.6% to + 9.6%). The benefit of extended duration was lower when using a weight-based ribavirin regimen (+8.7%; 95% CI: +1.7% to + 15.8%). In G1 rapid responders, a 24-week shortened duration decreased SVR (-12.5%; 95% CI: -19.2% to -5.8%) and increased relapse rates (+8.8%; 95% CI: +2.9% to + 14.8%). Such differences were not significant in patients with baseline viral load <400,000 UL/mL (-4.4%; 95% CI: -9.8% to + 1%). In G2/G3 rapid responders, SVR was more common for standard 24-week duration than for shortened durations (+4.1%; 95% CI: +0.1% to + 8.5), but this benefit was not significant when ribavirin was weight-adjusted and the short duration was 16 weeks (-1.7%; 95% CI: -6.1% to + 2.7%) and for G2 patients (+1.6%; 95% CI: -0.2% to + 5.5%). CONCLUSION: Long durations of P/R therapy improve SVR, regardless of genotype. This effect is nonetheless negligible in rapid responders, with the most favorable conditions for SVR (G2, G1 with low viral load, and G3 with weight-adjusted ribavirin regimen).
