Insights

Hepatitis C virus (HCV) infection in Punjab, Pakistan, is significantly associated with factors like age, blood transfusions, hospitalization, tattooing, family history of hepatitis, and surgical operations. Understanding these risk factors aids in predicting and managing HCV prevalence.

Area of Science:

  • Hepatology
  • Public Health
  • Epidemiology

Background:

  • Hepatitis C virus (HCV) poses a significant global health challenge, affecting approximately 3% of the world's population.
  • Punjab, Pakistan, experiences a notable burden of HCV infection, necessitating targeted research into its contributing factors.

Purpose of the Study:

  • To identify demographic, socio-economic, and clinical factors significantly associated with Hepatitis C virus infection in Punjab, Pakistan.
  • To determine the predictive strength of these associated factors using a logistic regression model.

Main Methods:

  • A hospital-based case-control study was conducted involving 400 patients (281 HCV-positive cases, 119 HCV-negative controls).
  • Data on risk factors were collected through interviews with patients admitted to gastroenterology wards in Lahore city hospitals.
  • Data collection occurred over a six-month period from April 2006 to September 2006.

Main Results:

  • Logistic regression analysis revealed significant positive associations between HCV infection and age (OR=1.035), history of blood transfusion (OR=9.204), history of hospitalization (OR=2.979), tattooing (OR=27.484), family history of hepatitis (OR=4.069), and surgical operation (OR=4.290).
  • All identified factors demonstrated statistically significant associations with HCV infection (p<0.05).

Conclusions:

  • The developed logistic regression model effectively predicts the likelihood of Hepatitis C virus infection based on the presence or absence of identified significant risk factors.
  • These findings can inform public health strategies for HCV prevention and control in the region.

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. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
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 create...
Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
