B96.22
Other specified Shiga toxin-producing Escherichia coli [E. coli] [STEC] as the cause of diseases classified elsewhere
Clinical Classification Guidelines
Inclusion Terms
- Non-O157 Shiga toxin-producing Escherichia coli [E. coli]
- Non-O157 Shiga toxin-producing Escherichia coli [E. coli] with known O group
Medical Intelligence & Overview
Shiga toxin-producing Escherichia coli (STEC), including non-O157 strains, are types of bacteria that can cause illness in humans. These bacteria produce toxins known as Shiga toxins, which can lead to severe gastrointestinal symptoms and other complications. The ICD-10 code B96.22 specifically refers to infections caused by other specified non-O157 STEC strains where the exact bacterial group is identified. Understanding this condition can help in recognizing its causes, symptoms, and available treatments.
Causes & Symptoms
Clinical Causes: Consumption of contaminated food products, especially undercooked meats, unpasteurized dairy, and contaminated produce. Contact with infected individuals or surfaces contaminated with STEC bacteria. Exposure to contaminated water sources, including lakes, streams, and swimming pools. Environmental exposure in settings such as daycare centers, or during travel to regions with poor hygiene practices.
Key Symptoms: Diarrhea, which may be bloody or non-bloody. Abdominal cramps and pain. Nausea and vomiting. Fever, typically low-grade. In some cases, more severe complications such as hemolytic uremic syndrome (HUS), which can cause kidney failure. Fatigue and general feeling of illness.
Diagnostic & Treatment
Diagnosis Path: Healthcare providers may perform stool tests to detect the presence of STEC bacteria. Additional laboratory tests, such as blood work and kidney function tests, might be conducted if severe symptoms or complications like HUS are suspected. Precise identification of the bacterial strain helps determine the type of STEC involved, which is important for understanding the potential severity. Clinicians also review patient history, including recent food intake and exposure risks.
Treatment Protocols: Management of STEC infections primarily includes supportive care such as staying well-hydrated and resting. Antibiotics are generally not recommended, as they may increase the risk of complications such as HUS. In severe cases, hospitalization may be necessary to monitor kidney function and support organ health. Antibiotics and certain medications may be contraindicated because they could worsen the illness. Prompt medical attention is important if symptoms worsen or complications are suspected.
