Insights

Pruritus is less common in the inactive phase of chronic hepatitis B (CHB) compared to the immune-active phase. Inactive CHB is an independent protective factor against pruritus in hepatitis B virus patients.

Area of Science:

  • Hepatology
  • Viral Hepatitis
  • Dermatology

Background:

  • Pruritus is a frequent symptom in liver diseases, including chronic hepatitis B (CHB).
  • Hepatitis B virus (HBV) infection has distinct phases, but their independent effect on pruritus is not well-defined.

Purpose of the Study:

  • To investigate the association between HBV infection phase and pruritus in patients with CHB.
  • To determine if the inactive CHB phase independently influences pruritus prevalence.

Main Methods:

  • Retrospective analysis of 196 CHB patients from a cohort of 1,631.
  • One-to-one propensity score matching (13 variables) comparing immune-active and inactive CHB phases.
  • Pruritus prevalence assessed via patient interviews.

Main Results:

  • Pruritus prevalence was significantly lower in the inactive CHB phase (23%) versus the immune-active phase (47%; P=0.031).
  • Inactive CHB phase was identified as an independent protective factor against pruritus (OR, 0.35; 95% CI, 0.143-0.842; P=0.019).

Conclusions:

  • The inactive phase of CHB is associated with a reduced risk of pruritus.
  • Progression to the inactive CHB phase may alleviate pruritus in patients with HBV infection.

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Stages of Infection

Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Urinary Tract Infection I: Introduction

Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...
