Abstract

Insights

This case study details an adult with Neisseria meningitidis W-135 infection presenting atypically with both meningococcal arthritis and myopericarditis. Early treatment with ceftriaxone led to a favorable outcome.

Area of Science:

  • Infectious Diseases
  • Cardiology
  • Rheumatology

Background:

  • Reports a rare adult case of Neisseria meningitidis W-135 infection.
  • Highlights an atypical presentation without classical meningococcal disease symptoms.

Observation:

  • A 67-year-old male presented with acute polyarthralgia, myalgia, and fever.
  • Clinical findings included polyarticular synovitis, ECG changes indicative of myopericarditis, and elevated troponin.
  • Cardiac MRI revealed pericardial enhancement; Neisseria meningitidis W-135 was identified in synovial fluid and blood.

Findings:

  • Successful treatment with intravenous ceftriaxone and supportive care for myopericarditis.
  • Demonstrates Neisseria meningitidis W-135 as a cause of concurrent septic arthritis and myopericarditis.

Implications:

  • Suggests primary meningococcal arthritis may be an atypical presentation of disseminated meningococcal disease.
  • Emphasizes the importance of considering disseminated meningococcal disease in cases of unexplained arthritis and myopericarditis.

Pericarditis I: Introduction01:22

Pericarditis I: Introduction

Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Pericarditis III: Medical Management01:17

Pericarditis III: Medical Management

The primary objectives of managing pericarditis are to determine the underlying cause, provide effective therapy for treatment and symptom relief, and promptly detect signs and symptoms of cardiac tamponade. The following outlines the essential aspects of medical management for pericarditis:ObjectivesDetermine the Cause: Identifying the underlying cause of pericarditis is crucial for targeted treatment. Causes include viral infections, autoimmune diseases, post-cardiac injury syndrome, and...

Endocarditis III: Medical Management

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...

Endocarditis I: Introduction01:25

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Myocarditis I: Introduction

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...
