Insights

Transfusion-transmitted hepatitis B (HBV) and C (HCV) infections remain a concern, particularly for multi-transfused patients. Systematic blood donor screening significantly reduced these risks.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Public Health

Background:

  • Transfusion-transmitted infections (TTIs) persist despite advancements in prevention.
  • Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections pose a significant risk to multi-transfused patients in Uruguay.

Purpose of the Study:

  • To determine the prevalence of HBV and HCV infections in multi-transfused patients in Uruguay.
  • To assess the impact of systematic serological screening on TTI rates.
  • To identify risk factors, including transfusion volume and patient characteristics, associated with HBV and HCV acquisition.

Main Methods:

  • A cross-sectional study was conducted involving 409 multi-transfused patients.
  • Serological testing for HCV antibodies, HBV surface antigen (HBsAg), and HBV core antibodies (HBcAc) was performed.

Main Results:

  • Overall HCV antibody prevalence was 12.7%, with significantly higher rates in hemophiliacs (60.0%).
  • HBV infection markers (HBsAg and HBcAc) were found in 1.0% and 16.6% of patients, respectively.
  • A direct correlation was observed between the number of transfusions and the prevalence of HCV antibodies and HBcAc, with higher rates in patients transfused before systematic donor screening.

Conclusions:

  • Blood transfusions are identified as the primary risk factor for HCV and HBV infection in this cohort.
  • Systematic serological screening of blood donors proved highly effective in mitigating transfusion-transmitted HBV and HCV.

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...
Jaundice01:25

Jaundice

Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...
Portal Hypertension01:22

Portal Hypertension

Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
Viral Hepatitis I: Introduction01:28

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...

Pharmacogenetics of Phase II Enzymes: N-acetyltransferase, Thiopurine S-methyltransferase, UDP-glucuronosyltransferase

Phase II biotransformation reactions are essential for detoxifying and eliminating xenobiotics, including many pharmaceutical compounds. These reactions typically involve conjugation, the covalent attachment of polar endogenous groups such as glucuronic acid, sulfate, methyl, or acetyl moieties to functional groups introduced during Phase I metabolism. The resulting conjugates are more water-soluble, enabling efficient renal or biliary excretion.The major classes of Phase II enzymes include...
