RESUMO

INTRODUCTION: Noninvasive criteria to predict the progression of low-risk esophageal varices (EV) in patients with compensated hepatitis C virus (HCV) cirrhosis after sustained virological response (SVR) by direct-acting antivirals (DAAs) are lacking. Our aim was to assess the diagnostic performance of Rete Sicilia Selezione Terapia-HCV (RESIST-HCV) criteria for EV progression compared with elastography-based criteria (Baveno VI, Expanded Baveno VI, and Baveno VII-HCV criteria). METHODS: All consecutive patients observed at 3 referral centers with compensated HCV cirrhosis with or without F1 EV who achieved sustained virological response by DAAs were classified at last esophagogastroduodenoscopy (EGDS) as RESIST-HCV low risk (i.e., low probability of high-risk varices [HRV]) if platelets were >120 × 10 9 /L and serum albumin >3.6 g/dL or RESIST-HCV high risk (i.e., high probability of HRV) if platelets were <120 × 10 9 /L or serum albumin <3.6 g/dL. The primary outcome was the progression to HRV. The area under the receiver operating characteristic curve and decision curve analysis of noninvasive criteria were calculated. RESULTS: The cohort consisted of 353 patients in Child-Pugh class A (mean age 67.2 years, 53.8% males). During a mean follow-up of 44.2 months, 34 patients (9.6%, 95% CI 6.7%-13.5%) developed HRV. At the last EGDS, 178 patients (50.4%) were RESIST-low risk, and 175 (49.6%) were RESIST-high risk. RESIST-HCV criteria showed the highest area under the receiver operating characteristic curve (0.70, 95% confidence interval 0.65-0.75), correctly sparing the highest number of EGDS (54.3%), with the lowest false-positive rate (45.7%), compared with elastography-based criteria. Decision curve analysis showed that RESIST-HCV had higher clinical utility than elastography-based criteria. DISCUSSION: Biochemical-based RESIST-HCV criteria are useful to easily predict HRV development after HCV eradication by DAAs in patients with compensated cirrhosis and low-risk EV.

RESUMO

Background and Aims: Endoscopic band legation (EBL) is an effective method for the prophylaxis of acute variceal bleeding (AVB). This procedure may be associated with several complications, particularly bleeding. Our analysis aimed to evaluate the risk of complications due to EBL in a cohort of patients who underwent EBL for the prophylaxis of variceal bleeding and the eventual presence of risk predictors. Patients and Methods: We retrospectively analysed data from consecutive patients who underwent EBL in a primary prophylaxis regimen. For all patients, simultaneously with EBL, we recorded the Child-Pugh and MELD score, platelet count and US features of portal hypertension. Results: We collected data from 431 patients who performed a total of 1028 EBLs. We recorded 86 events (8.4% of all procedures). Bleeding after EBL occurred 64 times (6.2% of all procedures), with the following distribution: intraprocedural bleeding in 4%; hematocystis formation in 17 cases (1.7%); 6 events (0.6%) of AVB due to post-EBL ulcers. None of these events presented a correlation with platelet count (84,235 ± 54,175 × 103/mL vs. 77,804 ± 75,949 × 103/mL; p = 0.70) or with the condition of severe thrombocitopenia established at PLT < 50,000/mmc (22.7% with PLT ≤ 50,000/mmc vs. 15.9% with PLT ≥ 50,000/mmc; p = 0.39). Our results showed a relationship between cumulative complications of EBL and Child-Pugh score (6.9 ± 1.6 vs. 6.5 ± 1.3; p = 0.043). Conclusions: EBL in cirrhotic patients is a safe procedure. The risk of adverse events depends on the severity of liver disease, without a relationship with platelet count.

RESUMO

Macular edema is a major cause of vision loss in patients with central retinal vein occlusion (CRVO) or branch retinal vein occlusion (BRVO). It is not clear how much of the edema is due to hydrodynamic changes from the obstruction and how much is due to chemical mediators. Patients with macular edema due to CRVO (n = 20) or BRVO (n = 20) were randomized to receive three monthly injections of 0.3 or 0.5 mg of ranibizumab. At the primary endpoint, month 3, the median improvement in letters read at 4 m was 17 in the 0.3-mg group and 14 in the 0.5-mg group for CRVO, and 10 and 18, respectively for the BRVO group. Optical coherence tomography (OCT) showed that compared to injections of 0.3 mg, injections of 0.5 mg of ranibizumab tended to cause more rapid reductions of central retinal thickening that lasted longer between injections, but in 3 months, excess central retinal thickening which is a quantitative assessment of the macular edema, was reduced by approximately 90% in all four treatment groups. There was no correlation between the amount of improvement and duration of disease or patient age at baseline, but there was some correlation between the aqueous vascular endothelial growth factor (VEGF) level at baseline and amount of improvement. These data indicate that excess production of VEGF in the retinas of patients with CRVO or BRVO is a major contributor to macular edema and suggest that additional studies investigating the efficacy of intraocular injections of ranibizumab are needed.

RESUMO

The purpose of this study was to evaluate changes in knowledge and attitudes as intermediate measures of community impact of a health education campaign using newspaper articles. The intervention involved prominently placed, illustrated newspaper articles by Heartfile (heartfile.org) with nationwide urban outreach, posted regularly in the largest English newspaper in Pakistan using newspaper donated space for a period of 130 consecutive weeks. The post intervention evaluation involved a cross sectional telephone survey in a major city. In the total sample, 26.5% were readers of the newspaper and majority of them (72%) stated that they were regular readers. These 500 persons were eligible for the interview; of these, 93% remembered having seen the Heartfile articles. In this group, 87% of the respondents stated that the articles significantly supplemented their knowledge about diet, and in 5% they were the sole source of information. With respect to exercise, these articles supplemented the knowledge of 77% of the respondents and were the sole source of information for 9% whereas in the case of smoking, knowledge was supplemented in 85% and the articles were the sole source of information in 4% of the cases. Of those interviewed, 40% reported that they had made some dietary changes, 39% made some changes in their exercise habits and 8% reduced the amount of tobacco consumption as a result of reading these articles. In relation to newspaper articles, the per article production cost was US$ 169 and the articles were read regularly by an estimated 0.66 million and occasionally by 0.79 million individuals all over the country. Newspaper articles are a useful supplement to other health education activities as part of cardiovascular disease prevention programs. Lessons from the Heartfile experience in Pakistan could be useful for other similar initiatives in low resource settings.
