Abstract
Background: Specific antibody deficiency is a primary immunodeficiency characterized by normal immunoglobulins with an inadequate response to polysaccharide antigen vaccination. This disease can result in recurrent infections, the most common being sinopulmonary infections. Treatment options include clinical observation, prophylactic antibiotic therapy, and immunoglobulin supplementation therapy, each with limited clinical data about their efficacy. Objective: This study aimed to identify whether there was a statistically significant difference in the rate of infections for patients who were managed with clinical observation, prophylactic antibiotics, or immunoglobulin supplementation therapy. Methods: A retrospective chart review was conducted. Patients were eligible for the study if they had normal immunoglobulin levels, an inadequate antibody response to polysaccharide antigen-based vaccination, and no other known causes of immunodeficiency. Results: A total of 26 patients with specific antibody deficiency were identified. Eleven patients were managed with immunoglobulin supplementation, ten with clinical observation, and five with prophylactic antibiotic therapy. The frequency of antibiotic prescriptions was assessed for the first year after intervention. A statistically significant rate of decreased antibiotic prescriptions after intervention was found for patients treated with immunoglobulin supplementation (n = 11; p = 0.0004) and for patients on prophylactic antibiotics (n = 5; p = 0.01). There was no statistical difference in antibiotic prescriptions for those patients treated with immunoglobulin supplementation versus prophylactic antibiotics (p = 0.21). Conclusion: Prophylactic antibiotics seemed to be equally effective as immunoglobin supplementation therapy for the treatment of specific antibody deficiency. Further studies are needed in this area.

Abstract
Cirrhosis is a chronic liver disease stage that encompasses a variety of etiologies resulting in liver damage. This damage may induce secondary complications such as portal hypertension, esophageal variceal bleeding, spontaneous bacterial peritonitis, and hepatic encephalopathy. Screening for and management of these complications incurs substantial health care costs; thus, determining the most economical and beneficial treatment strategies is essential. This article reviews the economic impact of a variety of prophylactic and treatment regimens employed for cirrhosis-related complications. Prophylactic use of β-adrenergic blockers for portal hypertension and variceal bleeding appears to be cost-effective, but the most economical regimen for treatment of initial bleeding is unclear given that cost comparisons of pharmacologic and surgical regimens are lacking. In contrast, prophylaxis for spontaneous bacterial peritonitis cannot be recommended. Standard therapy for spontaneous bacterial peritonitis includes antibiotics, and the overall economic impact of these medications depends largely on their direct cost. However, the potential development of bacterial antibiotic resistance and resulting clinical failure should also be considered. Nonabsorbable disaccharides are standard therapies for hepatic encephalopathy; however, given their questionable efficacy, the nonsystemic antibiotic rifaximin may be a more cost-effective, long-term treatment for hepatic encephalopathy, despite its increased direct cost, because of its demonstrated efficacy and prevention of hospitalization. Further studies evaluating the cost burden of cirrhosis and cirrhosis-related complications, including screening costs, the cost of treatment and maintenance therapy, conveyance to liver transplantation, liver transplantation success, and health-related quality of life after transplantation, are essential for evaluation of the economic burden of hepatic encephalopathy and all cirrhosis-related complications.

Abstract
Antimicrobial prophylaxis is commonly used by clinicians for the prevention of numerous infectious diseases, including herpes simplex infection, rheumatic fever, recurrent cellulitis, meningococcal disease, recurrent uncomplicated urinary tract infections in women, spontaneous bacterial peritonitis in patients with cirrhosis, influenza, infective endocarditis, pertussis, and acute necrotizing pancreatitis, as well as infections associated with open fractures, recent prosthetic joint placement, and bite wounds. Perioperative antimicrobial prophylaxis is recommended for various surgical procedures to prevent surgical site infections. Optimal antimicrobial agents for prophylaxis should be bactericidal, nontoxic, inexpensive, and active against the typical pathogens that can cause surgical site infection postoperatively. To maximize its effectiveness, intravenous perioperative prophylaxis should be administered within 30 to 60 minutes before the surgical incision. Antimicrobial prophylaxis should be of short duration to decrease toxicity and antimicrobial resistance and to reduce cost.

Abstract
BACKGROUND Spontaneous bacterial peritonitis is frequent among cirrhotic patients, associated with significant morbidity and mortality. Selective intestinal decontamination employing antibiotics is a proposed prophylactic measure. While data regarding this modality among cirrhotic patients with gastrointestinal bleeding exist, there is insufficient data synthesis regarding cirrhotic patients with ascites and no gastrointestinal bleeding. OBJECTIVES To assess whether antibiotic prophylaxis decreases spontaneous bacterial peritonitis and mortality among cirrhotic patients with ascites and no gastrointestinal bleeding. SEARCH STRATEGY We identified relevant randomised trials by searching trial registries of The Cochrane Hepato-Biliary Group and The Cochrane Collaboration, medical literature search engines, and reviewing all literature we found on the topic until February 2009. SELECTION CRITERIA We searched for randomised clinical trials assessing prophylactic treatment among adult cirrhotic patients with ascites and no gastrointestinal bleeding, comparing antibiotic therapy with no intervention, placebo, or with another antibiotic regimen. DATA COLLECTION AND ANALYSIS Three independent authors searched for and collected the trials and extracted relevant data. Four other independent authors validated the findings and assessed them. The studies were assessed for design, patient and intervention characteristics, and quality. A meta-analysis was performed to estimate measures of association between antibiotic prophylaxis and spontaneous bacterial peritonitis or mortality. MAIN RESULTS Nine trials were included in the review. Seven trials, comparing antibiotics to placebo or no treatment, were meta-analysed. Systematic bias in design or publication is suggested by trial results. The randomisation results suggest that the probability that true randomisation took place in all trials is very small and the report of most trials regarding design was poor. The proportion of participants with spontaneous bacterial peritonitis varied between the trials from 15% to 50%. The calculated relative risks (95% confidence interval) of spontaneous bacterial peritonitis and mortality among patients treated with antibiotics compared with no treatment/placebo were 0.20 (0.11 to 0.37) and 0.61 (0.43 to 0.87). There were very few reports of adverse events. AUTHORS' CONCLUSIONS The pooled estimates suggest that antibiotic prophylaxis might be prudent among cirrhotic patients with ascites and no gastrointestinal bleeding. However, poor trial methodology and report coupled with findings suggesting systematic bias in publication and design reflect the fragility of these findings. Potential hazard to society and the patients themselves from resistant pathogens should be considered when promoting long-lasting antibiotic prophylaxis. It seems that recommending antibiotic prophylaxis is still far from being a substantiated prevention strategy. Trials of better design, well reported, and of longer follow-up are greatly needed.

Abstract
Since its initial description in 1964, research has transformed spontaneous bacterial peritonitis (SBP) from a feared disease (with reported mortality of 90%) to a treatable complication of decompensated cirrhosis, albeit with steady prevalence and a high recurrence rate. Bacterial translocation, the key mechanism in the pathogenesis of SBP, is only possible because of the concurrent failure of defensive mechanisms in cirrhosis. Variants of SBP should be treated. Leucocyte esterase reagent strips have managed to shorten the ‘tap-to-shot’ time, while future studies should look into their combined use with ascitic fluid pH. Third generation cephalosporins are the antibiotic of choice because they have a number of advantages. Renal dysfunction has been shown to be an independent predictor of mortality in patients with SBP. Albumin is felt to reduce the risk of renal impairment by improving effective intravascular volume, and by helping to bind pro-inflammatory molecules. Following a single episode of SBP, patients should have long-term antibiotic prophylaxis and be considered for liver transplantation.

Abstract
BACKGROUND Diagnosis of spontaneous bacterial peritonitis (SBP) is currently based on ascitic cell counting, but there is a need for a more simple and rapid diagnostic tool. The objectives of this study are to evaluate the accuracy of reagent strips in diagnosing SBP and compare their costs with total and differential cell counts. PATIENTS AND METHODS 71 cirrhotic in- and outpatients were consecutively included (159 samples). Spontaneous bacterial peritonitis was defined as neutrophil cells >or= 250/microL. The cutoff values for each reagent strip were defined by a receiver operating characteristic (ROC) curve. Sensitivity (S), Specificity (Sp), Positive and Negative Predictive Values (PPV and NPV), Accuracy (Ac) and cost-effectiveness (US$) in comparison to cell count exam were calculated. RESULTS Spontaneous bacterial peritonitis was diagnosed in 17 patients (23.9%), 11 of them with positive culture (64.7%). The best cutoff points found in ROC curves were 1+ for Multistix 10 SG and ca. 75 for Choiceline 10 (Multistix 10 SG S = 80%, Sp = 98.5%, PPV = 90.9%, NPV = 96.2%, Ac = 95%; Choiceline 10 S = 76.9%, Sp = 97.7%, PPV = 87%, NPV = 95.6%, Ac = 94%). In terms of cost-effectiveness by cost/accuracy, cell count was 41.5, Multistix 10 SG 0.57, and Choiceline 10, 0.19 (P < 0.001). CONCLUSION Reagent strips are a useful tool for diagnosing SBP in cirrhotic patients, but they have some limitations. Strips are especially indicated when total and differential cell counts are not quickly available or sometimes unavailable. They are also indicated as screening test in emergency rooms to anticipate the diagnosis of SBP and allow its early treatment. It's an interesting option in developing countries.

Abstract
Spontaneous bacterial peritonitis (SBP) is the infection of ascitic fluid in the absence of any intra-abdominal, surgically treatable source of infection. Despite timely diagnosis and treatment its reported incidence in ascitic patients varies between 7-30%. Ascitic paracentesis remains the chief diagnostic procedure. Automated cell counters have the same diagnostic accuracy as the manual measurement of white cells. Lately, the use of leucocyte reagent strips (dipsticks) has emerged as a useful alternative. Examination of the fluid is not complete unless the sample is inoculated in blood culture bottles. Treatment is currently with third-generation cephalosporins or oral quinolones. Following a single episode of SBP patients should have long term antibiotic prophylaxis.

Abstract
Spontaneous bacterial peritonitis (SBP) is the prototypical ascitic fluid infection occurring in patients with advanced liver disease and ascites. The key to successful treatment of SBP is a knowledge of appropriate antibiotic regimens and an understanding of the setting in which infection develops, particularly those individuals at high risk for infection. A high index of suspicion should lead to early diagnostic paracentesis and ascitic fluid analysis. Treatment of SBP involves the use of non-nephrotoxic broad-spectrum antibiotics expected to cover the typical bacterial flora associated with SBP. SBP typically involves infection with a single organism, with Escherichia coli, Klebsiella spp, and Streptococcus spp responsible for nearly three fourths of cases. The treatment of choice is cefotaxime 2 g given intravenously every 8 hours for a total of 5 days. The antibiotic regimen is adjusted based on the results of ascitic fluid cultures. Other antibiotic regimens for SBP are less well studied. Given the significant morbidity and mortality rates associated with SBP, efforts to prevent its development and recurrence with antibiotic prophylaxis are warranted. The most extensively studied form of prophylaxis involves selective intestinal decontamination (SID) with the oral fluoroquinolone norfloxacin. Individuals with low-protein ascites (ascitic fluid total protein < 1g/dL) benefit from SID with norfloxacin 400 mg daily during times of hospitalization. Long-term primary prophylaxis during outpatient management of individuals awaiting liver transplantation with severe ascites and advanced liver failure should also be considered. Patients with cirrhosis and upper gastrointestinal bleeding should receive norfloxacin 400 mg twice daily for 1 week following their bleed. Those individuals surviving an episode of SBP should be treated with norfloxacin 400 mg daily until the risk of SBP is removed by definitive resolution of the ascites or liver transplantation surgery. Although the infection-related mortality associated with SBP has decreased to less than 10%, hospitalization-related mortality remains as high as 30% as a result of the severe underlying liver disease in which the infection arises and the marked generation of cytokines and nitric oxide resulting from the infection. Recently, the simultaneous administration of intravenous albumin and antibiotics for SBP has been shown to result in the decreased development of azotemia and hospitalization-related mortality. Further improvement in the outcomes of SBP will require treatments targeting this cytokine cascade rather than the development of more potent antibiotics.

Abstract
AIMS To evaluate the prevalence, incidence and clinical relevance of bacterial infection in predominantly non-alcoholic cirrhotic patients hospitalised for decompensation. PATIENTS/METHODS A total of 405 consecutive admissions in 361 patients (249 males and 112 females; 66 Child-Pugh class B and 295 class C) were analysed. Blood, urine, ascitic and pleural fluid cultures were performed within the first 24 hours, during hospitalisation whenever infection was suspected, and again before discharge. RESULTS Over a one year period, 150 (34%) bacterial infections (89 community- and 61 hospital-acquired) involving urinary tract (41%), ascites (23%), blood (21%) and respiratory tract (17%) were diagnosed. The prevalence of bacterial peritonitis was 12%. Infections were asymptomatic in 69 cases (46%) and 130 (87%) involved a single site. Enteric flora accounted for 62% of infections, Escherichia Coli being the most frequent pathogen (25%). Community-acquired infections were associated with more advanced liver disease (Child-Pugh mean score 10.2+/-2.1 versus 9.5+/-1.9, p<0.05), renal failure (p<0.05), and high white blood cell count (p<0.01). Hospital-acquired infections occurred more frequently in patients admitted for gastrointestinal bleeding (p<0.05). The in-hospital mortality was significantly higher in infected than in non-infected patients (15% versus 7%, p<0.05), and infection emerged as an independent variable affecting survival. Moreover bacterial infection accounted for a significantly prolonged hospital stay. CONCLUSIONS Bacterial infection, regardless of the aetiology, is a severe complication of decompensated cirrhosis, and, although frequently asymptomatic, accounts for both longer hospital stay and increased mortality.

Abstract
Spontaneous bacterial peritonitis (SBP) is a frequent complication in cirrhotic patients with ascites. Diagnosis of SBP is established by a polymorphonuclear cell count in ascitic fluid > or =250 cells/mm(3). The organism responsible for the infection is isolated in 60-70% of the cases. The remaining cases are considered to have a variant of SBP (culture-negative SBP) and are treated in the same way as those with a positive culture. The SBP resolution rate ranges between 70 and 90%, and hospital survival between 50 and 70%. An early diagnosis and the use of a more adequate antibiotic therapy are the most probable reasons for the improvement in prognosis for SBP in recent decades. Despite the resolution of the infection, SBP may trigger severe complications such as renal impairment, gastrointestinal bleeding and accentuation of hepatic insufficiency which are responsible for the associated mortality. Patients recovering from an episode of SBP should be considered as potential candidates for liver transplantation.

Abstract
Antimicrobial prophylaxis is used by clinicians for the prevention of numerous infections, including sexually transmitted diseases, human immunodeficiency virus infection, tuberculosis, rheumatic fever, recurrent cellulitis, meningococcal disease, recurrent uncomplicated urinary tract infections in women, spontaneous bacterial peritonitis in patients with cirrhosis, influenza, malaria, infective endocarditis, pertussis, plague, anthrax, early-onset group B streptococcal disease in neonates, and animal bite wounds. Certain opportunistic infections such as Pneumocystis carinii pneumonia in immunocompromised patients also can be effectively prevented with primary antimicrobial prophylaxis. Perioperative antimicrobial prophylaxis is recommended for various surgical procedures to prevent surgical site infection. Optimal antimicrobial agents for prophylaxis are bactericidal, nontoxic, inexpensive, and active against the typical pathogens that cause surgical site infection postoperatively. To maximize its effectiveness, intravenous perioperative prophylaxis should be given within 30 to 60 minutes before the time of surgical incision. Antibiotic prophylaxis should be of short duration to decrease toxicity, antimicrobial resistance, and excess cost.
