AIM:To identify clinical parameters, and develop an Upper Gastrointesinal Bleeding (UGIB) Etiology Score for predicting the types of UGIB and validate the score. METHODS:Patients with UGIB who underwent endoscopy within 72 h were enrolled. Clinical and basic laboratory parameters were prospectively collected. Predictive factors for the types of UGIB were identified by univariate and multivariate analyses and were used to generate the UGIB Etiology Score. The best cutoff of the score was defined from the receiver operating curve and prospectively validated in another set of patients with UGIB. RESULTS:Among 261 patients with UGIB, 47 (18%) had variceal and 214 (82%) had non-variceal bleeding. Univariate analysis identified 27 distinct parameters significantly associated with the types of UGIB. Logistic regression analysis identified only 3 independent factors for predicting variceal bleeding; previous diagnosis of cirrhosis or signs of chronic liver disease (OR 22.4, 95% CI 8.3-60.4, P < 0.001), red vomitus (OR 4.6, 95% CI 1.8-11.9, P = 0.02), and red nasogastric (NG) aspirate (OR 3.3, 95% CI 1.3-8.3, P = 0.011).The UGIB Etiology Score was calculated from (3.1 × previous diagnosis of cirrhosis or signs of chronic liver disease) + (1.5 × red vomitus) + (1.2 × red NG aspirate), when 1 and 0 are used for the presence and absence of each factor, respectively. Using a cutoff ≥ 3.1, the sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) in predicting variceal bleeding were 85%, 81%, 82%, 50%, and 96%, respectively. The score was prospectively validated in another set of 195 UGIB cases (46 variceal and 149 non-variceal bleeding). The PPV and NPV of a score ≥ 3.1 for variceal bleeding were 79% and 97%, respectively. CONCLUSION:The UGIB Etiology Score, composed of 3 parameters, using a cutoff ≥ 3.1 accurately predicted variceal bleeding and may help to guide the choice of initial therapy for UGIB before endoscopy.
BackgroundThe conventional antibiotic regimen for community-acquired upper urinary tract infections with moderate severity in Thailand is parenteral ceftriaxone (CTRX) for several days followed by oral cephalosporin for 7–14 days. The aim of this study was to compare the efficacy and safety of oral sitafloxacin (STFX) with that of intravenous CTRX followed by oral cefdinir (CFDN) for the therapy of acute pyelonephritis (APN) and complicated urinary tract infection (cUTI).MethodsThis open-label, randomized, controlled, noninferiority clinical trial included patients from nine centers across Thailand. Adult patients with APN or cUTI were randomly assigned to receive 100 mg of oral STFX twice daily for 7–14 days, or 2 g of intravenous CTRX for several days followed by 100 mg of oral CFDN three times per day for another 4–12 days.ResultsA total of 289 adult patients with APN or cUTI (141 in the STFX group and 148 in the CTRX/CFDN group) were included in the intent-to-treat (ITT) analysis, and 211 patients (108 in the STFX group and 103 in the CTRX/CFDN group) were included in the per-protocol (PP) analysis. The baseline characteristics of patients in both groups were comparable. The causative pathogen in most patients with APN or cUTI was Escherichia coli. The clinical success rates at the end of treatment revealed the STFX regimen to be noninferior to the CTRX/CFDN regimen (86.6% vs 83.8% for ITT analysis and 97.2% vs 99.0% for PP analysis, respectively). Adverse events with mild-to-moderate severity were similar between groups.ConclusionOral STFX is noninferior to intravenous CTRX followed by oral CFDN in adult patients with APN and cUTI. Lower rates of resistance compared to CTRX and/or CFDN and oral administration suggest STFX as a more attractive treatment option in this patient population.
BackgroundColistimethate sodium (colistin) has been used in the treatment of infections caused by extensively drug-resistant (XDR) Gram-negative bacteria in Thailand over the past decade, with a mortality rate of 50% and a nephrotoxicity rate of 40%. Polymyxin B has not been available in Thailand. We conducted a Phase II clinical study to determine the effectiveness and safety of polymyxin B, compared with colistin, for the treatment of XDR Gram-negative bacterial infections in Thai patients.MethodsA total of 73 adult patients hospitalized at four participating tertiary care hospitals from January 2015 to December 2015 who had infections caused by XDR Gram-negative bacteria and had to receive colistin were enrolled in the study. Polymyxin B (100 mg/day) was administered intravenously every 12 hours for 7–14 days.ResultsMost of the patients were older males with comorbidities who had received antibiotics, particularly carbapenems, prior to receiving polymyxin B. More than half of the patients had pneumonia, and 51.5% of the infections were caused by XDR Acinetobacter baumannii, which was susceptible to colistin. Good clinical responses at the end of treatment were observed in 78.1% of cases, the overall 28-day mortality rate from all causes was 28.7%, the microbiological clearance of the targeted bacteria after therapy was 56.2% and nephrotoxicity occurred in 24.7% of cases. Neurotoxicity relating to reversible numbness was observed in two cases.ConclusionPolymyxin B seems to be effective and safe for the treatment of XDR Gram-negative bacterial infections. Polymyxin B should be considered as an alternative to colistin for treatment of infections caused by XDR Gram-negative bacteria in Thai adult patients, especially those at risk of nephrotoxicity.
