Summary
Shigella boydii infection can cause severe heart inflammation (myopericarditis), a rare complication. Prompt antibiotic treatment led to recovery in a traveler returning from Africa.
Area of Science:
- Infectious Diseases
- Cardiology
- Microbiology
Background:
- Shigella infection, typically causing infectious diarrhea, is uncommon in developed nations.
- Extra-intestinal manifestations of shigellosis are diverse and can affect multiple organ systems.
Observation:
- A 38-year-old man presented with diarrhea, fever, and chest pain post-travel to Cape Verde.
- Cardiac enzyme elevation, ST-segment elevation on ECG, and pericardial effusion were noted.
- Stool cultures identified Shigella boydii as the causative agent.
Findings:
- The patient was diagnosed with acute myopericarditis secondary to Shigella boydii infection.
- Treatment with ciprofloxacin and acetylsalicylic acid resulted in clinical and laboratory improvement.
Implications:
- This case highlights Shigella as a potential cause of myopericarditis, even in non-endemic regions.
- Early identification and targeted antimicrobial therapy are crucial for managing severe extra-intestinal shigellosis.
- Clinicians should consider infectious etiologies, including Shigella, in patients presenting with myopericarditis and relevant travel history.

01:21Myocarditis 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...
01:27Myocarditis 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...
01:22Pericarditis 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...
01:14Myocarditis III: Medical Management
Myocarditis: Comprehensive Medical ManagementMyocarditis, the heart muscle inflammation, requires a comprehensive medical management strategy that addresses the underlying cause, provides supportive care, manages symptoms, and reduces cardiac workload.Infections and Autoimmune CausesAdminister appropriate antimicrobial therapy when an infectious agent causes myocarditis. For instance, penicillin treats infections caused by Group A Streptococcus. In cases where autoimmune processes are...
01:19Pericarditis II: Clinical Features and Diagnostic Tests
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...
01:17Pericarditis 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...
