A02.25
Salmonella pyelonephritis
Clinical Classification Guidelines
Inclusion Terms
- Salmonella tubulo-interstitial nephropathy
Medical Intelligence & Overview
Salmonella pyelonephritis is a rare kidney infection caused by Salmonella bacteria, specifically involving the renal pelvis and renal tissue. It is a form of kidney inflammation that results from the spread of Salmonella bacteria, which are most commonly known for causing foodborne illnesses. The condition, categorized under ICD-10 code A02.25, is a manifestation of Salmonella infection that affects the kidneys, leading to inflammation and potential complications if not diagnosed and managed properly. Often related to Salmonella tubulo-interstitial nephropathy, this condition highlights the importance of understanding bacterial causes behind kidney infections beyond the typical urinary pathogens.
Causes & Symptoms
Clinical Causes: Salmonella bacteria entering the bloodstream from contaminated food or water sources Spread of Salmonella from the gastrointestinal tract to the kidneys through hematogenous dissemination Pre-existing urinary tract infections that become complicated by systemic Salmonella infection Immunocompromised states that increase susceptibility to systemic Salmonella spread Poor hygiene or inadequate food handling practices
Key Symptoms: Fever and chills Flank pain or tenderness in the back or sides Hematuria (blood in the urine) Dysuria (painful urination) Malaise or general feeling of illness Nausea and vomiting Persistent urinary symptoms in some cases
Diagnostic & Treatment
Diagnosis Path: Diagnosis relies on a combination of clinical evaluation, laboratory testing, and imaging studies. Urinalysis may reveal leukocytes, bacteria, or blood in the urine. Blood cultures can identify Salmonella bacteria circulating in the bloodstream. Imaging studies, such as ultrasound or CT scans, help assess kidney inflammation or abscess formation. Specific laboratory techniques, including blood and urine cultures, are crucial to confirm Salmonella as the causative agent. A thorough medical history and physical examination are essential to distinguish Salmonella pyelonephritis from other types of renal infections.
Treatment Protocols: Treatment of Salmonella pyelonephritis generally involves the use of targeted antibiotics to eliminate the bacteria. The choice of antibiotics may depend on local antibiotic resistance patterns and sensitivity testing results. Supportive care, including hydration and pain management, is important for recovery. In severe cases or if complications such as abscesses develop, hospitalization and surgical intervention may be necessary. Addressing underlying predisposing factors and preventing recurrence are also important aspects of management.
