Staphylococcal Enterocolitis: A Forgotten Gastrointestinal Pathogen

Staphylococcal enterocolitis (SEC) is a condition caused by the bacterium Staphylococcus aureus, which can lead to diarrhea and enteritis. This condition was first recognized in the mid-20th century and has been described as both a complication of antibiotic therapy and as occurring in individuals with predisposing conditions.

Symptoms and Characteristics

The symptoms of SEC include large-volume, cholera-like diarrhea, which is distinct from Clostridium difficile-associated diarrhea. Other symptoms may include violent vomiting, fever, and unspecific symptoms like headache and nausea [1][2]. The condition can occur as a complication of antibiotic therapy or in individuals with predisposing conditions but without preceding antibiotic treatment.

History and Recognition

SEC was first recognized almost 70 years ago, and since then, there have been sporadic cases and outbreaks reported in infants. Prematurity and low birth weight are the major predisposing factors for this condition [3]. Despite its recognition, SEC has largely been overshadowed by other gastrointestinal pathogens like Clostridium difficile.

Comparison with Other Gastrointestinal Pathogens

SEC can be differentiated from Clostridium difficile-associated diarrhea based on the presence of large-volume, cholera-like diarrhea. In contrast, C. difficile infection is often characterized by pseudomembranous colitis and a more severe clinical course [4].

Prevalence and Impact

While there is limited information available on the prevalence and impact of SEC, it is estimated that foodborne illness causes 5,020 deaths annually, with unknown agents accounting for a significant portion of these deaths [5]. This highlights the need for further research into this condition.

Diagnostic Tests for Staphylococcal Enterocolitis

Staphylococcal enterocolitis, a condition caused by the bacterium Staphylococcus aureus, can be challenging to diagnose. However, several diagnostic tests can help identify this condition.

• Gram stain of biopsy specimens: A gram stain test can be used to detect the presence of S. aureus in biopsy samples from the affected area (1).
• Isolation of S. aureus: Culturing a sample from the affected area and identifying the presence of S. aureus through laboratory tests is another diagnostic method (5).
• Clinical history and exclusion of other enterocolitides: A thorough clinical history and exclusion of other possible causes of enterocolitis can also aid in diagnosis (1).

Additional Tests

In some cases, additional tests may be recommended to confirm the diagnosis or rule out other conditions. These may include:

• Blood tests: Blood tests can help identify signs of infection or inflammation caused by S. aureus.
• Urine tests: Urine tests can also detect the presence of S. aureus in the urine.
• Skin, infected material, or nasal secretions tests: Testing these samples for signs of S. aureus can aid in diagnosis (13).

Note

It's essential to note that while these diagnostic tests can help identify staphylococcal enterocolitis, a definitive diagnosis may require a combination of clinical history, laboratory tests, and exclusion of other possible causes.

Treatment Options for Staphylococcal Enterocolitis

Staphylococcal enterocolitis, a condition caused by the bacteria Staphylococcus aureus, was once considered a significant medical concern. While it is still a treatable condition, its prevalence has decreased with advancements in medicine and hygiene.

Historical Treatment Options

In the past, treatment for staphylococcal enterocolitis involved various medications, including:

• Vancomycin: This antibiotic was commonly used to treat infections caused by Staphylococcus aureus. Oral vancomycin was particularly effective in treating enterocolitis (1, 2, 3).
• Firvanq: Another medication, Firvanq, was also indicated for the treatment of enterocolitis caused by Staphylococcus aureus, including methicillin-resistant strains (5).

Current Treatment Options

While staphylococcal enterocolitis is still a treatable condition, its incidence has decreased significantly. As such, current treatment options may not be as extensive as they were in the past.

However, oral vancomycin remains an effective treatment option for enterocolitis caused by Staphylococcus aureus (6).

Based on the provided context, it appears that staphylococcal enterocolitis is an uncommon condition that was previously considered in the differential diagnosis of gastrointestinal disorders.

Possible Differential Diagnoses:

• Acute mesenteric vascular insufficiency: This condition can present with similar symptoms to staphylococcal enterocolitis, such as abdominal pain and diarrhea (Context #3).
• Salmonella food poisoning: Foodborne illnesses like Salmonella can cause gastrointestinal symptoms that may be mistaken for staphylococcal enterocolitis (Context #3).
• Rotavirus gastroenteritis: This viral infection can cause severe diarrhea and vomiting, which may be confused with the symptoms of staphylococcal enterocolitis (Context #3).
• Mesenteric venous thrombosis: A blood clot in the mesenteric veins can cause abdominal pain and gastrointestinal symptoms that may be similar to those seen in staphylococcal enterocolitis (Context #3).
• Ulcerative colitis: This chronic inflammatory bowel disease can present with similar symptoms to staphylococcal enterocolitis, such as diarrhea and abdominal pain (Context #6).

Other Considerations:

• Neutropenic enterocolitis: This condition is a type of inflammation in the intestines that occurs in people with weakened immune systems (Context #12).
• Chemical colitis: Certain chemicals, such as those used in chemotherapy or gold therapy, can cause gastrointestinal symptoms that may be mistaken for staphylococcal enterocolitis (Context #12).

It's essential to note that these conditions were previously considered in the differential diagnosis of staphylococcal enterocolitis. However, with advancements in medical knowledge and understanding, the importance of staphylococcal enterocolitis as a distinct condition may have diminished.
