The 2014 Hepatology Society of the Philippines consensus statements on the management of chronic hepatitis B

Chorinic hepatitis B virus (CHB) infection is a serious problem that affects over 300 million people worldwide and is highly prevalent in the Asia Pacific region. In the Philippines an estimate 7.3 million Filipinos or 16.7% of adults are chronically infected with HBV, more than twice the average prevalence in the Western Pacific region. In view of the above, the Hepatology Society of the Philippines (HSP) embarked on the development of consensus statements on the management of hepatitis B with the primary objectives of standardizing approach to management, empowering other physicians involved in the management of hepatitis B and advancing treatment subsidy by the Philippine Health Insurance Corporation (PhilHealth). The local guidelines include screening and vaccination general management, indications for assessment of fibrosis in those who did not meet treatment criteria. indications for treatment, on-treatment and post-treatment monitoring and duration of antiviral treatment. Recommendations on the management of antiviral drug resistance, management of special populations including patients with concurrent HIV or hepatitis C infection, women of child-bearing age (pregnancy and breastfeeding), patients with decompensated liver disease, patients receiving immunosuppressive medications or chemotherapy and patients in the setting of hepatocellular carcinoma are also included. However, the guidelines did not include management for patients with liver and other solid organ transplantation, patients on renal replacement therapy, and children. The consensus statements will be amended accordingly as new therapies become available.

The 2014 Hepatology Society of the Philippines consensus statements on the diagnosis and treatment of hepatitis C

Hepatitis C virus (HCV) infection is a devastating disease that is increasingly being diagnosed among Filipinos, especially in at-risk populations. There are disease-specific nuances in the evaluation and management of this infection. Furthermore, advances in the field brought about by clinical research are rapidly moulding the way we evaluate and manage HCV patients. Evidently, consensus statements formulated by experts in the field are needed in order to serve as a guide to physicians who see HCV patients in the clinic. With this in mind, the Hepatology Society of the Philippines spearheaded the formation of these statements which aimed to address issues in the diagnosis, evaluation, treatment, and follow-up care of patients with HCV infection.Recommendations on the specific tests to perform in the evaluation of HCV patients before, during and after treatment, and first-line treatment of patients with acute and chronic HCV infection were provided. Treatment algorithms for chronic HCV infection, divided according to viral genotype, were also devised. We acknowledge the limitations brought about by the local inavailability of some drugs/treatment regimens in the local setting at the time of the formulation of these statements. As such, these statements will be revised as soon as new data become locally applicable.  

Hepatitis B infection among adults in the philippines: A national seroprevalence study.

AIM: To determine the prevalence of hepatitis B surface antigen (HBsAg) seropositivity among adult Filipinos. METHODS: Testing for HBsAg was performed on serum samples from persons aged ≥ 20 years old who participated in the National Nutrition and Health Survey (NNHeS) conducted in 2003. Information on age, sex, marital status, educational attainment, employment status, and income were collected. For this study, marital status was classified as never married or otherwise (i.e., married, divorced, separated, widowed); educational attainment was classified as high school graduate or below or at least some tertiary education; and employment status was classified as currently employed or currently unemployed. Annual income was divided into 4 quartiles in Philippine pesos (PhP): Q1, ≤ PhP 53064; Q2, PhP 53065-92192; Q3, PhP 92193-173387; and Q4, ≥ PhP 173388. Prevalence estimates were weighted so that they represented the general population. Social and demographic factors were correlated with HBsAg seropositivity. Multivariate analysis was used to determine independent predictors of HBsAg seropositivity. RESULTS: A total of 2150 randomly selected adults, 20 years and over, out of the 4753 adult participants of NNHeS were tested for HBsAg. The HBsAg seroprevalence was 16.7% (95%CI: 14.3%-19.1%), which corresponded to an estimated 7278968 persons infected with hepatitis B. There was no significant difference between males and females (17.5% vs 16.0%; P = 0.555). This corresponded to an estimated 3721775 men and 3557193 women infected with hepatitis B. The HBsAg seroprevalence peaked at age 20-39 years old, with declining prevalence in the older age groups. The only independent predictor of HBsAg seropositivity was the annual income, with persons in the highest income quartile being less likely to be HBsAg positive (age-adjusted OR = 0.51; 95%CI: 0.30-0.86) compared to subjects in the lowest income quartile. Sex, marital status, educational attainment, and employment status were not found to be independent predictors of HBsAg seropositivity. CONCLUSION: The high HBsAg seroprevalence among adults in the Philippines classifies the country as hyperendemic for HBV infection and appears unchanged over the last few decades.
