Some colonoscopists recommend hemoclip closure of PPIU’s but this has mixed success rates in different RCT’s and is reported not to be cost effective. In addition to known risks, arterial blood flow detected in PPIU’s is an important predictor of DPPIUH. Our AIMS are to report study methods and interim results of a RCT of blood flow monitoring to prevent DPPIUH. Methods: This is an ongoing blinded RCT at several major Los Angeles Medical Centers by experienced colonoscopists. Outpatients having colonoscopies are screened and consented for enrollment. Sessile and multilobulated polyps are removed by EMR techniques. Thermal coagulation is used for polypectomies in this study. Randomized patients are stratified by whether they take chronic anti-platelet or anti-thrombotic drugs and have PPIU’s of 10-40 mm;or those without bleed drugs and have PPIU’s between 15-40 mm. By opening a sealed envelope after polypectomies, randomization is to either standard management (e.g. following ASGE guidelines of bleed drugs) or DEP interrogation of the PPIU and guided treatment of the artery with hemoclips or multipolar probe coagulation in the PPIU until blood flow is eradicated. Patients and their care givers were blinded to treatments allocated during colonoscopy. Prospective follow-up is by a research coordinator contacting each patient at 7, 14, and 30 days to record whether any complications (e.g. pain, vomiting, or bleeding);or rectal bleeding and its severity (e.g. # and days of bloody BM’s);whether they sought ER, clinic, or telemedicine care for bleeding;or were hospitalized. Major DPPIUH was diagnosed in patients with hospitalization for severe bleeding and/or for 3 or more days of ongoing severe rectal bleeding but refusal of hospitalization because of high rates of COVID here. Demographic, laboratory, colonoscopic, and pathology results are recorded on standard forms along with 30-day outcomes. Patients are assigned a code, data are entered onto HIPAA compliant computer files by a data manager and managed with SAS. With half the projected sample size randomized and followed up (e.g. 133 of 268 total), this is a planned interim analysis of the primary outcome - rates of DPPIUH by treatment. Severe adverse events (SAE’s) were also reviewed. Results: For 133 high risk patients randomized to date, 67 are in the standard group and 66 in the DEP group. The groups were well matched in risk factors – see Table 1. Overall, the Doppler group had lower rates of delayed PPIU bleeding – both major and total- see Table 2. There were no SAE’s. Conclusions: The major DPPIUH rate was higher with standard treatment than DEP treatment (7.46 % vs. 0 %), as was the rate of Total DPPIUH (10.45 % vs. 1.52%). Based upon these promising results, this RCT will continue. [Formula presented] [Formula presented]

ABSTRACT

Background: The COVID19 pandemic has affected persons dietary habits and life style, with effects on body weight. We have assessed the effect of the pandemic on the liver health by quantifying the changes in liver enzymes, hepatic steatosis and fibrosis in patients with chronic liver disease. Methods: This is a multi-center US study that included 3 tertiary clinical centers. Patients with chronic liver disease (51 NAFLD, 8 with resolved hepatitis C, 3 chronic hepatitis B, 5 primary biliary cholangitis and 36 combination of chronic liver disease), without evidence of an acute process (e.g. alcoholic hepatitis, alcohol abuse or new decompensation of cirrhosis), were enrolled. Patients were assessed between January and March 2020 and January and March 2021. Assessment included laboratory tests and controlled attenuation parameter (CAP) and liver stiffness measurement (LSM) on vibration transient elastography (VCTE). Results: 103 patients were assessed twice during the two periods. Baseline mean alanine aminotransferase (ALT) was 37 ± 36 (SD) U/L;aspartate aminotransferase (AST) 30 ± 18 U/L;total bilirubin 0.6 ± 0.31 mg/dL;albumin, 4.2 ± 0.72 g/dL;CAP score 293 ± 70 dB/m;and LSM on VCTE 8.1 ±6.2 kPa. Weight gain occurred in 54% of the population, whereas 39% lost weight, and 7% had no weight change. LSM increased by >20% in 30% of subjects;decreased by 20% in 27%;and remained within the 20% range in 43%. LSM increase by 20% was associated with significant weight gain and ALT increase (+2.3 ± 6.5 kg, and +17 ± 49.U/L (p<0.05)), in comparison to subjects who had their LSM changes within 20% range (+1.1 (3.7) kg, and -5.3 ±22.0 U/L) or had >20% decrease in LSM (-0.3 ±5.8 kg, and -6.0 ±21 U/L). CAP score median change was -2.9 ±85 dB/m in those who had LSM increase by >20%, whereas the score changed by 0.0 ± 44 dB/m in those who had LSM changes within 20% or 1.0 ± 58 dB/m in those >20% decrease. Conclusion: During the COVID 19 pandemic in this U.S. population, more than half of subjects with chronic liver disease gained weight, but others had no change or decreased weight. Adverse liver changes (LSM>20% and increased ALT) occurred in one-third of the population.
