Pruritus is one of the disturbing complications induced by chronic liver disease (CLD), bearing a negative impact on patient quality of life and potentially resulting in early liver transplants. Given the main role of the autotaxin enzyme in pruritus induced by CLD and the suppressive effects of melatonin on the expression of the autotaxin gene, this study was designed to evaluate the antipruritic effect of melatonin in patients with CLD. A double-blind, cross-over, randomized, placebo-controlled pilot trial was conducted on patients with CLD -induced pruritis. Patients were randomly assigned to two groups where they received melatonin 10-mg at night or placebo for 2 weeks. After a 2-week washout period, patients were then crossed over to the other group. The Visual Analog Scale (VAS) and the 12-Item Pruritus Severity Score (12-PSS) were used to assess patient response to therapy as the co-primary outcomes, while liver function tests were assayed too. Forty patients completed the study. The VAS score showed alleviation of 3.21 ± 2.24 (in pruritus) with melatonin (p-value <0.05). The study goal (a reduction of at least 20% in VAS) was achieved in 33 (82%) of study participants. In patients who received melatonin, the 12-PSS and Body Surface Area (BSA) affected by pruritus decreased on average 46.57% and 51.71%, respectively, with mood, sleep pattern and daily activity levels also demonstrating significant improvement (p-value < 0.05). Melatonin was found to be effective for managing pruritus in patients with CLD.

The coronavirus associated disease 2019 (COVID-19) caused by the SARS-CoV-2 virus has rapidly spread all around the world and became pandemic in March 2020. Data on liver transplantation and chronic liver disease during the pandemic has remained scarce, and there is little information on whether immunosuppressed patients are at higher risk of developing severe COVID-19 infection. This review provides information for health care providers who care for patients with liver transplantation and chronic liver diseases.

Background: We aim to present incidence rates and geographical distribution of most common early-onset gastrointestinal cancers (EOGICs), including early-onset esophageal cancer (EOEC), gastric cancer (EOGC) and colorectal cancer (EOCRC) in Iran, 2014-2018. Methods: Data on new cases of EOEC, EOGC and EOCRC were obtained from publicly available annual reports of the Iranian National Population-based Cancer Registry (INPCR). Incidence rates were calculated using the population data available from the Statistical center of Iran. We considered the World standard population for calculation of age-standardized incidence rates (ASR). We also calculated 95% confidence intervals (CIs) for ASR. All rates are presented per 100000 person-years. Results: Overall, 19,679 new cases of EOGIC were registered by the INPCR between 2014 and 2018. The ASRs (95% CI) of EOEC, EOGC and EOCRC were 0.49 (95% CI: 0.47–0.51), 1.67 (1.63–1.71), and 3.07 (3.01–3.13) per 100,000 person-years, respectively. Our findings indicate decreasing and constant trends in the ASR of EOEC and EOGC during the study period, 2014-2018. There was an increasing trend in the ASR of EOCRC. We also found geographical disparities in the incidence rates of EOGICs across provinces of Iran, suggesting the highest ASRs of EOEC in Golestan (1.3), EOGC in Ilam (2.99) and EOCRC in Ilam (4.49). Conclusion: Our findings suggested that the incidence rate of EOCRC is consistently increasing. We also found variations in the incidence of EOGICs among different provinces. Further investigations are recommended to clarify the time trends and risk factors of EOGICs in Iran.

We evaluated the response to Trans-arterial chemoembolization (TACE) in hepatocellular carcinoma (HCC) patients according to modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria. We determined the prognostic value of the neutrophil-to-lymphocyte ratio (NLR). TACE is the most commonly used method to treat patients with large, unresectable tumors or as bridge therapy in patients with HCC before liver transplantation. In this cross-sectional study, patients with a diagnosis of HCC who were referred for TACE were studied. The response rate to TACE treatment was assessed based on dynamic MRI 28 days after treatment according to mRECIST criteria. The NLR value was calculated, and its prognostic value was evaluated to predict the response to treatment. Forty patients with HCC who underwent TACE were included. The response to TACE treatment included a complete response (CR) in 6 patients (15%), partial response (PR) in 16 patients (40%), and stable disease (SD) in 18 patients (45%). No progressive disease (PD) was found. Responders (CR and PR) were 22 patients (55%). The mean NLR after treatment in the non-responders was significantly higher than in the responders (4.2 vs. 2.4, P-value = 0.026). NLR values greater than 2.6 after treatment had a sensitivity of 70.6% and a specificity of 77.3% in diagnosing non-responders, with an Area Under the Curve (AUC) of 0.73 [95% confidence interval 0.58-0.89], P-value = 0.011. Non-responders observed higher levels of NLR after treatment than responders. As a moderate prognostic factor, an NLR level of more than 2.6 after treatment could discriminate against non-responders.

Background Trans-arterial chemoembolization (TACE) is commonly used for patients with large, un-resectable tumors or bridge therapy in patients with hepatocellular carcinoma (HCC) prior to liver transplantation. We evaluated the response to TACE treatment in patients with hepatocellular carcinoma according to modified RECIST criteria and determined the prognostic value of neutrophil-to-lymphocyte ratio (NLR). Methods Patients with definitive diagnosis of HCC referred for TACE were studied. The response rate to TACE treatment was assessed based on dynamic MRI 28-days after treatment according to modified RECIST. The NLR value was calculated and its prognostic value was evaluated to predict the response to treatment. Results Forty patients with HCC who underwent TACE were included in the study. The response to TACE treatment in included patients was: complete response (CR) in 6 patients (15%), partial response (PR) in 16 patients (40%) and stable disease (SD) in 18 patients (45%). No progressive disease (PD) was found. Responders (CR+PR) were 22 (55%) cases. The mean NLR after treatment in the non-responder group was significantly higher than the responder group (4.2 vs 2.4, P-value=0.026). NLR values greater than 2.6 after treatment had a sensitivity of 70.6% and a specificity of 77.3% in the diagnosis of non-responders with an Area Under the Curve of 0.73 [95% confidence interval 0.58–0.89], P-value=0.011). Conclusion Compared to responders, higher levels of NLR after treatment were observed in the non-responder group. NLR level more than 2.6 after treatment is believed to be able to discriminate non-responders as a moderate prognostication tool.
