Splenomegaly in acute infections due to group A streptococci and viruses

Insights

Enlarged spleen (splenomegaly) can temporarily occur with common infections like pharyngitis. Group A streptococci and viral infections were frequently associated with this finding in general practice.

Area of Science:

  • General Practice
  • Infectious Diseases
  • Pediatrics

Background:

  • Splenomegaly, or enlarged spleen, is a clinical sign that can be associated with various infections.
  • Understanding the common causes of temporary splenomegaly in primary care settings is important for accurate diagnosis.

Purpose of the Study:

  • To investigate the incidence and potential causes of temporary splenomegaly observed in general practice over a nine-year period.

Main Methods:

  • Retrospective analysis of general practice records over 9 years.
  • Identification of episodes of splenomegaly and associated clinical diagnoses.
  • Microbiological and serological investigations to determine causative agents.

Main Results:

  • Thirty-seven episodes of temporary splenomegaly were recorded, most commonly associated with pharyngitis/tonsillitis (29 episodes).
  • Identified aetiologies included Group A streptococci (14 episodes), adenoviruses/coxsackie B viruses (4 episodes), and atypical mononuclear cells (4 episodes).
  • Four episodes showed evidence of both streptococcal and viral infections. Streptococcal-only infections were shorter and year-round.

Conclusions:

  • Temporary splenomegaly is a notable finding in various common infections, particularly streptococcal pharyngitis and viral upper respiratory tract infections.
  • Prompt identification of causative agents like streptococci and viruses aids in understanding the duration and presentation of illness.

Acute Pharyngitis01:30

Acute Pharyngitis

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Tonsillitis I: Introduction01:30

Tonsillitis I: Introduction

Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
Etiology
Three primary contributing factors have been identified.
Bacterial Meningitis01:24

Bacterial Meningitis

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
Streptococcal Pharyngitis01:27

Streptococcal Pharyngitis

Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Cytomegalovirus Disease01:27

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...
