This is the first systematic review and meta-analysis to compare the second-line imunossupressant therapy for AIH. The most studied second-line immunosuppressive is the MM, with a reasonable histological remission. The use of combined tacrolimus/prednisone was the most effective for the normalization of aminotransferases.

Background: Gallstones and alcohol are currently the most frequent aetiologies of acute pancreatitis (AP). The aim of this study is to quantify these aetiologies worldwide, by geographic region and by diagnostic method.Methods: A systematic review of observational studies published from January 2006 to October 2017 was performed. The studies provided objective criteria for establishing the diagnosis and aetiology of AP for at least biliary and alcoholic causes. A random-effects meta-analysis was used to assess the frequency of biliary (ABP), alcoholic (AAP) and idiopathic AP (IAP) worldwide and to perform 6 subgroup analyses: 2 compared diagnostic methods for AP aetiology and the other 4 compared geographic regions. Results: Forty-six studies representing 2,341,007 patients of AP in 36 countries were included. The global estimate of proportion (95% CI) of aetiologies was 42 (39-44)% for ABP, 21 (17-25)% for AAP and 18 (15-22)% for IAP. In studies that used discharge code diagnoses and in those from the US, IAP was the most frequent aetiology. ABP was more frequent in Latin America than in other regions. Conclusion:Gallstones represent the main aetiology of AP globally, and this aetiology is twice as frequent as the second most common aetiology.

These results highlight the need for the revision of algorithm for VL diagnostic in Brazil. Replacements of IFAT with DAT-LPC, Kalazar Detect with IT LEISH and bone marrow aspirate performed in a hospital setting with PCR are cost-effective public health measures.

The accuracy of estimated glomerular filtration rate (eGFR) equations in diabetes mellitus (DM) patients has been extensively questioned. We evaluated the performance of cystatin C-based equations alone or in combination with creatinine to estimate GFR in DM patients. A PRISMA-compliant systematic review was performed in the MEDLINE and Embase databases, with “diabetes mellitus” and “cystatin C” as search terms. Studies comparing cystatin C-based eGFR equations with measured GFR (mGFR) in DM patients were eligible. Accuracies P10, P15, P20, and P30 indicated the proportion of eGFR results within 10, 15, 20, and 30% of mGFR. Single-arm meta-analyses were conducted, and the Quality of Diagnostic Accuracy Studies-II tool (QUADAS-2) was applied. Twenty-three studies comprising 7065 participants were included, and 24 equations were analyzed in a broad range of GFRs. Meta-analyses were completed for 10 equations. The mean P30 accuracies of the equations ranged from 41% to 87%, with the highest values found with both CKD-EPI equations. Mean P10-P15 achieved 35% in the best scenario. A sensitivity analysis to evaluate different mGFR methods did not change results. In conclusion, cystatin C-based eGFR equations represent measured GFR fairly at best in DM patients, with high variability among the several proposed equations.

Introduction:The drugs available for visceral leishmaniasis (VL) treatment in Brazil have specific characteristics in terms of operability, effectiveness, toxicity, and cost. The aim of this study was to estimate the direct costs of therapies recommended by the Ministry of Health (MH) for VL treatment in Brazil. Methods: The analytical perspective used was that adopted by the Brazilian Public Health System. Three drugs and four regimens were included: 1) N-methyl glucamine antimoniate intramuscularly at 20mg per kg per day for 30 days; 2) N-methyl glucamine antimoniate intravenously at 20mg per kg per day for 30 days; 3) amphotericin B deoxycholate at 1mg per kg per day for 21 days; and 4) liposomal amphotericin B at 3mg per kg per day for a 7 days treatment. Results: The estimated direct costs of treatment for an adult patient using N-methylglucamine antimoniate administered via the intramuscular and intravenous routes were USD 418.52 and USD 669.40, respectively. The estimated cost of treatment with amphotericin B deoxycholate was USD 1,522.70. Finally, the estimated costs of treatment with liposomal amphotericin B were USD 659.79, and USD 11,559.15 using the price adopted by the WHO and the Drug Regulation Board, respectively. Conclusions: This analysis indicates the economic feasibility of replacing N-methyl glucamine antimoniate with liposomal amphotericin B, which allows a shorter treatment period with less toxicity compared with other treatments, provided that the purchase value used by the WHO and transferred to the MH is maintained.

Background and aim  Guidelines recommend use of ligation and vasoactive drugs as first-line therapy and as grade A evidence for acute variceal bleeding (AVB), although Western studies about this issue are lacking. Methods  We performed a systematic review and meta-analysis of randomized controlled trials (RCT) to evaluate the efficacy of endoscopic treatments for AVB in patients with cirrhosis. Trials that included patients with hepatocellular carcinoma, use of portocaval shunts or esophageal resection, balloon tamponade as first bleeding control measure, or that received placebo or elective treatment in one study arm were excluded. Results  A total of 8382 publications were searched, of which 36 RCTs with 3593 patients were included. Ligation was associated with a significant improvement in bleeding control (relative risk [RR] 1.08; 95 % confidence interval [CI] 1.02 – 1.15) when compared to sclerotherapy. Sclerotherapy combined with vasoactive drugs showed higher efficacy in active bleeding control compared to sclerotherapy alone (RR 1.17; 95 % CI 1.10 – 1.25). The combination of ligation and vasoactive drugs was not superior to ligation alone in terms of overall rebleeding (RR 2.21; 95 %CI 0.55 – 8.92) and in-hospital mortality (RR 1.97; 95 %CI 0.78 – 4.97). Other treatments did not generate meta-analysis. Conclusions  This study showed that ligation is superior to sclerotherapy, although with moderate heterogeneity. The combination of sclerotherapy and vasoactive drugs was more effective than sclerotherapy alone. Although current guidelines recommend combined use of ligation with vasoactive drugs in treatment of esophageal variceal bleeding, this study failed to demonstrate the superiority of this combined treatment.

Published economic evaluations indicate that more intensive care is likely to be cost-effective in comparison to routine hospital admission for patients with suspected ACS.
