Summary
Hepatitis A virus infection is rarely linked to kidney problems. This case report details a patient with Hepatitis A, nephrotic syndrome, IgA-dominant glomerulonephritis, and cutaneous cryoglobulinemic vasculitis.
Area of Science:
- Nephrology
- Hepatology
- Immunology
Background:
- Renal involvement is exceptionally rare in Hepatitis A virus (HAV) infection, unlike Hepatitis B and C.
- Nephrotic syndrome is a documented, albeit uncommon, complication of HAV infection.
Observation:
- This report describes a patient with serologically confirmed HAV infection presenting with nephrotic syndrome.
- Renal biopsy revealed IgA-dominant glomerulonephritis (GN) with subendothelial immune deposits.
Findings:
- This is the second biopsy-proven case of acute HAV associated with IgA-dominant immune complex glomerulonephritis and nephrotic syndrome.
- This case may be the first to document concurrent IgA-dominant glomerulonephritis and cutaneous cryoglobulinemic vasculitis in a patient with acute HAV.
Implications:
- This case expands the understanding of potential renal manifestations of Hepatitis A.
- It highlights the importance of considering HAV as a potential trigger for glomerulonephritis and vasculitis in specific clinical contexts.
- Further research may elucidate the mechanisms linking HAV to these complex renal and systemic immune responses.

01:24Nephrotic Syndrome I : Introduction
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...
01:25Hepatitis
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...
01:28Amebiasis
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...
01:26Gastritis II: Pathophysiology
The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
01:28Viral 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...
01:29Hepatic Encephalopathy
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
