Living-Donor Liver Transplant in Oman: A Quantitative Cross-Sectional Study of Donors' Experiences and Challenges.

BACKGROUND: In Oman, the first liver transplant was performed at the Royal Hospital (RH) in September 2017. Since then, thirteen cases have been operated on at the RH. All of these cases were living-donor liver transplants (LDLT), and the remaining cases were treated in India with a total of approximately 193 recipients. To provide an in-depth overview of donor experiences, challenges, and perceptions, a cross-sectional study was conducted. METHODS: A cross-sectional study was conducted at one tertiary hospital in 2019. The survey was designed to collect data composed of closed and open-ended questions to reveal a thorough knowledge of the topic. RESULTS: A total of 50 of 120 donors responded to the survey with male dominance in the sample (68%) and 64% were aged 28 to 38 years. 66% of the respondents came to know about the donation through hospital staff. Interestingly, respondents (n = 8/12) who reported that fear of operation is the cause that prevents people from donating are among the male gender, while more men believe that the main cause is lack of knowledge. 90% of the respondents felt satisfied after donation. More men reported ambiguous feelings before donation. Moreover, married donors reported ambiguous feelings before donation (p = 0.008). The younger age group reported anxiety and doubt as a challenge through their donation experience. CONCLUSION: This study revealed that donors have a positive feeling after donating as they have saved a life, as well as being empowered by family and community. The donors encourage individuals to donate a portion of their liver. Some crucial questions arose, such as anxiety before surgery, ambiguous feelings before surgery, and fatigue after surgery. These findings underscore the importance of a holistic approach that would enable donors to be well informed prior to surgery.

Hepatocellular Carcinoma in Oman: An analysis of 284 cases.

OBJECTIVES: Hepatocellular carcinoma (HCC) is the most common type of primary liver tumour worldwide and is increasing in incidence. This study aimed to describe the clinical characteristics of HCC among Omani patients, along with its major risk factors, outcomes and the role of surveillance. METHODS: This retrospective case-series study was conducted between January 2008 and December 2015 at the three main tertiary care hospitals in Oman. All adult Omani patients diagnosed with HCC and visited these hospitals during the study period were included. Relevant data were collected from the patients' electronic medical records. RESULTS: A total of 284 HCC patients were included in the analysis. The mean age was 61.02 ± 11.41 years and 67.6% were male. The majority had liver cirrhosis (79.9%), with the most common aetiologies being chronic hepatitis C (46.5%) and B (43.2%). Only 13.7% of cases were detected by the HCC surveillance programme. Approximately half of the patients (48.5%) had a single liver lesion and 31.9% had a liver tumour of >5 cm in size. Approximately half (49.2%) had alpha-fetoprotein levels of ≥200 ng/mL. The majority (72.5%) were diagnosed using multiphase computed tomography alone. Less than half of the patients (48.9%) were offered one or more HCC treatment modalities. CONCLUSION: The majority of Omani HCC patients were male and had cirrhosis due to viral hepatitis. In addition, few patients were identified by the national surveillance programme and presented with advanced disease precluding therapeutic or even palliative treatment.

The efficacy of hepatitis B treatments in achieving HBsAg seroclearance: A systematic review and meta-analysis.

Current therapies for chronic hepatitis B (CHB) include nucleos(t)ide analogues (NAs) and interferon (IFN), but their relative efficacy as monotherapy or in combination has not been examined systematically for HBsAg loss (functional cure). Hence, we systematically reviewed the evidence for HBsAg loss in CHB patients treated with IFN, NA or the combination. We searched PubMed, EMBASE and abstracts from EASL, Asia Pacific Association for study of the Liver and American Association for the Study of Liver Disease for randomized controlled trials of CHB patients, comparing NA, IFN or the combination. The Cochrane Risk of Bias tool v2.0 and GRADE method were used. Analyses were stratified by NA genetic barrier, cirrhosis, type of combination therapy, HBeAg, treatment naivety, IFN dosage/duration and outcome duration. Sensitivity analysis was performed for selected strata, and HBsAg loss was measured at the end-of-study (EOS), end-of-treatment (EOT) or end-of-follow-up (EOF). Effects were reported as risk differences (RD) with 95% confidence intervals (CI) using a random-effects model. Forty-five studies were included, all with low risk of bias. For HBsAg loss at EOS, when comparing combination vs IFN, RD = 1%, 95%CI-1%, 2%; combination vs NA, RD = 5%, 95%CI 3%,7%; IFN vs NA, RD = 3%, 95%CI 2%,5%. Subgroup analysis showed a significant effect of standard IFN dose vs nonstandard; IFN duration ≥48 weeks vs <48 weeks, and loss of efficacy >2 years of follow-up. Similar findings were seen in HBsAg seroconversion, but only three studies reported HBsAg seroreversion. In conclusion, IFN monotherapy/combination had a small but significant increase in HBsAg loss over NA, associated with standard dose of IFN and ≥48 weeks of therapy, although this effect faded over time.
