Can hepatitis C virus be eliminated by 2030? Saudi Arabia as an example
2018
The World Health Organization (WHO) has announced its aim to eliminate hepatitis C virus (HCV) worldwide by 2030 (90% reduction of new HCV cases and 65% reduction in mortality).1 Many countries in the world are underway to achieve this ambitious plan but Saudi Arabia has not yet started according to the recent WHO report. In this brief report, we will explore how this aim can be achieved and examine the epidemiology, health and economic impact and challenges of HCV elimination in Saudi Arabia.

Background:
Primary biliary cholangitis (PBC) is a progressive autoimmune cholestatic liver disease that primarily affects females more than males and may lead to end-stage liver disease. We studied baseline characteristics, and the biochemical and clinical response to ursodeoxycholic acid (UDCA), a first-line treatment option for patients with PBC, in a cohort of patients diagnosed with PBC from Saudi Arabia.
Methods:
A total of 30 patients meeting the diagnostic criteria of PBC who were being followed in the King Faisal Specialist Hospital and Research Centre in Riyadh, Saudi Arabia, between January 1, 2008, and December 31, 2017, were enrolled in the study. The patients with autoimmune hepatitis, primary sclerosing cholangitis, and overlap syndromes were excluded. The baseline characteristics of the patients were recorded. The response to UDCA treatment was assessed according to the Barcelona, Paris I, Paris II, and Toronto criteria, and clinical outcomes, and biochemical changes were ascertained.
Results:
The mean age was 46 years ± 11.7 with a female gender predominance of 93% (n = 28). Pruritus was the predominant symptom reported by 90% (n = 27) of the patients. A total of 23 (77.7%) patients underwent liver biopsy and all of them showed histological features suggestive of PBC. Cirrhosis was documented in 30% (n = 9) of the patients at baseline. Overall, 86.7% (n = 26) of the patients were positive for antimitochondrial antibodies. The biochemical response rates to UDCA based on Paris I, Paris II, Barcelona, and Toronto criteria were 73.3, 40, 56.7, and 53.3%, respectively.
Conclusion:
Over 10 years, 30 patients with PBC were diagnosed at a large referral center in Saudi Arabia. The response to UDCA treatment was inadequate.

The field of hepatology has evolved significantly over the last two decades. Hepatology practice in Saudi Arabia (SA) was dominated by hepatitis B and C viruses but is now being overtaken by patients with non-alcoholic fatty liver disease. These patients require greater medical attention as their care is more complex compared to patients with viral hepatitis. In addition, liver transplantation (LT) has expanded significantly in SA over the last three decades. There is a necessity to increase the hepatology workforce to meet the demand in SA. The time has come to reinforce the transplant hepatology fellowship program, that was launched recently, and to develop a nurse practitioner practice model to meet these demands. In addition, SA is going through a health care reform to enhance health care delivery which may affect the financial compensation polices of various specialties including gastroenterology and hepatology. Therefore, the Saudi Association for the Study of Liver diseases and Transplantation (SASLT) established a task force to discuss the current and future demands in the hepatology workforce in SA, as well as to discuss different avenues of financial compensation for transplant hepatologists in LT centers.

Greater prevalence of comorbidities with increasing age: Cross-sectional analysis of chronic hepatitis B patients in Saudi Arabia
2019
Middle Eastern countries, including Saudi Arabia to some extent, are endemic for chronic hepatitis B (CHB) infection which could be associated with high mortality and comorbidities risk. However, limited data characterizing this CHB population exists. Our aim was to characterize and compare CHB patients in 2015 with those in 2010 and 2012 in Saudi Arabia.
We conducted and compared three cross-sectional analyses of adult patients with CHB defined as either positive hepatitis B surface antigen or documented CHB history in 2010, 2012, and 2015. Data were accessed from the multicenter Systematic Observatory Liver Disease Registry (SOLID).
A total of 765 CHB patients were identified in 2010 (n = 274), 2012 (n = 256), and 2015 (n = 235). Median age was significantly higher in 2015 (47 years) compared to 2010 and 2012 (42 years;P < 0.05). The proportions of patients with hepatocellular carcinoma (range 1-12%) and cirrhosis (range 5-23%) were significantly higher in 2015 compared to 2010 and 2012 (P < 0.05). Compared to 2010, patients in 2015 had significantly (P < 0.05) higher prevalence of coronary artery disease (10% vs. 4%) and hyperbilirubinemia (18% vs. 9%). Although not significant, there was a numerical increase in 2015 in chronic kidney disease (9% vs. 7% in 2010;P= 0.559) and hepatic steatosis (32% vs. 25% in 2010;P= 0.074). Significantly more patients in 2015 (P < 0.05) were treatment experienced (23% vs. 5% in 2010/2012) and switched treatment (17% vs. 1-2% in 2010/2012).
Between 2010 and 2015, the CHB population in Saudi Arabia had significantly aged and was more likely to develop liver disease sequelae and other comorbidities.

Abstract
Hepatitis C virus (HCV) infection has been a major global health concern, with a significant impact on public health. In recent years, there have been remarkable advancements in our understanding of HCV and the development of novel therapeutic agents. The Saudi Society for the Study of Liver Disease and Transplantation formed a working group to develop HCV practice guidelines in Saudi Arabia. The methodology used to create these guidelines involved a comprehensive review of available evidence, local data, and major international practice guidelines regarding HCV management. This updated guideline encompasses critical aspects of HCV care, including screening and diagnosis, assessing the severity of liver disease, and treatment strategies. The aim of this updated guideline is to assist healthcare providers in the management of HCV in Saudi Arabia. It summarizes the latest local studies on HCV epidemiology, significant changes in virus prevalence, and the importance of universal screening, particularly among high-risk populations. Moreover, it discusses the promising potential for HCV elimination as a public health threat by 2030, driven by effective treatment and comprehensive prevention strategies. This guideline also highlights evolving recommendations for advancing disease management, including the treatment of HCV patients with decompensated cirrhosis, treatment of those who have previously failed treatment with the newer medications, management in the context of liver transplantation and hepatocellular carcinoma, and treatment for special populations.

The prevalence of non-alcoholic fatty liver disease (NAFLD) is increasing in Saudi Arabia (SA), but descriptions of the clinical and metabolic characteristics of these patients are limited. The present study aims to fill this gap.
Demographic, clinical, and laboratory data of all NAFLD patients from 2009 to 2019 were retrieved from the Systematic Observatory Liver Disease Registry (SOLID) [n=832 (337 males; 495 females); mean (± standard deviation, SD) age was 42.6±13.6 years; mean body mass index (BMI) was 35.0±9.3kg/m
]. Non-invasive surrogate scores of fibrosis (eg AST to Platelet Ratio Index (APRI), Fibrosis-4 (FIB-4), and NAFLD fibrosis (NFS) scores) were calculated and analyzed. In addition, data from NAFLD patients with normal and high alanine aminotransferase (ALT) were compared using two different methods: the standard laboratory reference range which defines normal as ALT<61 IU/L, and the range proposed by a recent national study which sets upper limits of normal ALT at 33 IU/l for men and 22 IU/l for women.
Hyperlipidemia was the most common comorbidity (41.7%), followed by type 2 diabetes mellitus (T2DM) (35.3%) and hypertension (28.4%). Prevalence of advanced fibrosis varied widely across definitions [FIB-4, N=19 (2.5%); APRI, N=21 (2.8%); NFS, N=62 (8.6%)] and exhibited sexual dimorphism with males having worse metabolic characteristics. NAFLD patients with normal ALT were more likely to be older, female, have a lower BMI, and have a higher prevalence of cirrhosis, DM, hypertension, hyperlipidemia, and renal dysfunction.
Patients with NAFLD have metabolic characteristics associated with several comorbidities, including NAFLD patients with normal ALT. Mechanistic studies are needed to examine and analyze complex, interactive effects between sex, age, and other factors that may accelerate NAFLD disease progression.

Organ transplantation is still the treatment of choice for end-stage organ failure.
Despite the establishment of the Saudi Center for Organ Transplantation (SCOT), the organ
supply still does not meet the increasing demand. This study aims to assess the knowledge of
Saudis about organ donation both among the public and the medical staff and to assess the trend
in the change from 1996 until now. A cross-sectional study was conducted among Saudis above the
age of 18 years. A self-administered, 25-item, questionnaire was completed by participants inclu- ding both outpatients and medical staff at King Abdulaziz Medical City using a convenient sam- pling technique. A total of 376 individuals answered the questionnaire; 238 (63.1%) heard about
SCOT, of whom 124 (70.5%) were males. Health-care professionals had better attitude and know-
ledge on organ donation (P <0.05). Compared to the results from 1996to 2017, there was (51.22%)
to (30.4%) decrease in people who allowed their families to donate their organs; on the other hand,
there was an increase in the percentage of people who had the correct knowledge that Islam
supports organ donation. Unsatisfactory levels of awareness impacted negatively on the know-
ledge and attitude of the population that is showed by the minor improvements over the years, and
the slight proportion of participants who owned a donor card. Although 97.6% of the participants
knew about the concept of organ donation, only 66.5% were familiar with the positive Islamic
opinion. Based on the results of the comparison with the study in 1996, we conclude that more
efforts from both the governmental and religious authorities are needed to increase awareness.

Diminished accuracy of biomarkers of fibrosis in low replicative chronic hepatitis B
2017
Background
We evaluated the diagnostic accuracy of aspartate aminotransferase (AST)-to-platelet ratio index (APRI), fibrosis-4 index (FIB-4), AST/alanine aminotransferase (ALT) ratio (AAR), and age-platelet index (API) for significant fibrosis (Metavir F2–4) in low-replicative (HBV DNA <20,000 IU/mL) chronic hepatitis B virus (HBV) patients.
Methods
The sensitivity, specificity, and area under the receiver-operating characteristic curve (AUROC) of HBeAg-negative, low-replicative (
n
= 213) and high-replicative (HBV DNA ≥20,000 IU/mL,
n
= 153) patients was assessed.
Results
Overall, 113 patients (30.9%) had F2–4 fibrosis. Of the low and high-replicative patients, 40 (18.8%) and 73 (47.7%) had F2–4, respectively (
P
< 0.0001). APRI ≥0.5 less frequently identified F2–4 fibrosis in low vs. high-replicative patients (48.7% vs. 69.6%,
P
= 0.032) and AAR identified it more frequently in low-replicative patients (37.5% vs. 19.4%,
P
= 0.037). FIB-4 and API were not different (
P
> 0.05) for identifying F2–4 fibrosis in low and high-replicative patients. Higher specificities were seen at the lowest cut-offs in low vs. high-replicative states for APRI (≥0.5, 98% vs. 68.9%), AAR (84.3% vs. 76.6%), FIB-4 (≥1.45, 97.5% vs. 87.8%) and API (>4, 94.8% vs. 93.8%). At ROC-defined thresholds, APRI (≥0.33), AAR (≥0.93), FIB-4 (≥0.70) and API (>2) showed greater AUROCs for F2–4 diagnosis in low replicative (0.80, 0.62, 0.81 and 0.71, respectively) vs. high-replicative patients (0.73, 0.52, 0.67 and 0.69, respectively).
Conclusion
All 4 biomarkers in both, low and high-replicative HBV demonstrate modest accuracy for fibrosis diagnosis at conventional cut-offs. Lowering the cut-offs may increase the diagnostic relevance of these biomarkers, particularly for APRI and FIB-4 in low-replicative disease.

Background: In chronic hepatitis B virus (HBV) patients, fluctuations in HBV DNA serve as a \"gray area\" and impede the accurate identification of inactive carriers. We aimed to assess if such fluctuations impact the presence of significant hepatic fibrosis (Metavir F2-4) in chronic HBV patients.
Methods: Consecutive, untreated HBeAg-negative carriers (n = 234) with fluctuating HBV DNA (n = 73) above or below a level of 2000 IU/mL were included and compared to those without fluctuations (n = 161). Patients without fluctuating HBV DNA were further analyzed based on those with persistently low (<2,000 IU/mL, n = 137) and higher HBV DNA (2,000-20,000 IU/mL, n = 24). Hepatic fibrosis (assessed by transient elastography) was correlated with virologic and biochemical profiles.
Results: The mean age of the overall cohort was 47.8 ± 11.1 years, of whom 107 (45.7%) were male. During a median of 60 months (interquartile range [IQR] 34-82) of follow-up, 73 (31.2%) patients had a mean of 1.6 ± 0.9 fluctuations in HBV DNA. The median time to the first fluctuation was at 14.5 (IQR 5.0-33.7) months. Patients with fluctuating viremia had higher log10 qHBsAg (3.1 ± 0.8 vs. 2.7 ± 1.0, P = 0.022) and HBV DNA (3.4 ± 0.5 vs. 2.7 ± 0.8, P < 0.001) compared to those without fluctuations. Patients with fluctuant viremia were less likely to have F2-4 fibrosis (8.2%) compared to those without fluctuant viremia (18.2%, odds ratio [OR]: 0.407, 95% confidence interval [CI]: 0.161-1.030; P = 0.052). Males tended to have less fluctuation constituting 37.0% of patients with fluctuating HBV DNA (P = 0.071). Fluctuations occurred more frequently in those with predominantly higher HBV DNA levels (26.0%) compared to those without fluctuations (14.9%; P = 0.030).
Conclusions: Fluctuating HBV DNA levels occur frequently but are not associated with significant fibrosis. Minor fluctuations in HBV DNA levels are unlikely to be of clinical relevance.
