Hepatitis

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

Chronic Pharyngitis

Chronic Pharyngitis

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Viruses with RNA Genomes

Viruses with RNA Genomes

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Cytomegalovirus Disease

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Chronic Pancreatitis I: Introduction

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Summary

Chronic hepatitis B (CHB) affects millions in the Philippines due to low vaccination and treatment access. Urgent, nationally supported programs are needed for screening, vaccination, and treatment to prevent severe liver disease and reduce societal costs.

Area of Science:

Hepatology
Public Health
Infectious Diseases

Background:

Chronic hepatitis B (CHB) infection shows a high prevalence in the Philippines, impacting both high-risk groups and the general population.
Recent national data indicate an HBsAg seroprevalence of 16.7%, translating to approximately 7.3 million affected adults.
Inadequate vaccination and limited treatment access contribute significantly to the high CHB burden and its severe health consequences.

Purpose of the Study:

To highlight the critical need for comprehensive national strategies to combat the high prevalence of CHB in the Philippines.
To emphasize the importance of addressing factors contributing to CHB transmission and progression.
To advocate for expanded healthcare coverage and public education initiatives for hepatitis B.

Main Methods:

Review of existing studies on CHB prevalence in the Philippines.
Analysis of factors contributing to CHB infection and its sequelae.
Assessment of current healthcare access and financial barriers to prevention and treatment.

Main Results:

An estimated 7.3 million Filipino adults are living with CHB, with a national HBsAg seroprevalence of 16.7%.
Significant gaps exist in vaccination coverage and access to medical monitoring and treatment for CHB.
Without intervention, CHB carries a 25-30% risk of progression to liver failure and death, incurring substantial medical and societal costs.

Conclusions:

There is an urgent need for a nationally supported program in the Philippines to address CHB.
Key interventions include universal newborn vaccination, nationwide screening and vaccination, and accessible monitoring and treatment for CHB patients.
Addressing transmission routes in healthcare settings, through drug use, and tattooing, alongside expanded government coverage for prevention and treatment, is crucial for mitigating the impact of CHB.
