N00.1
Acute nephritic syndrome with focal and segmental glomerular lesions
Clinical Classification Guidelines
Inclusion Terms
- Acute nephritic syndrome with focal and segmental hyalinosis
- Acute nephritic syndrome with focal and segmental sclerosis
- Acute nephritic syndrome with focal glomerulonephritis
Medical Intelligence & Overview
Acute nephritic syndrome with focal and segmental glomerular lesions is a kidney condition that involves inflammation and damage to the glomeruli, which are tiny filtering units within the kidneys. This syndrome is characterized by sudden onset of symptoms such as blood in the urine, swelling, and decreased kidney function. The term 'focal and segmental' indicates that only certain parts, or segments, of some glomeruli are affected. Recognizing this condition is important because prompt diagnosis and management can help prevent further kidney damage.
Causes & Symptoms
Clinical Causes: Immune system disorders, such as post-infectious glomerulonephritis or lupus Infections, including streptococcal infections Vascular diseases that affect small blood vessels in the kidneys Certain medications or toxins Genetic predisposition in some cases
Key Symptoms: Blood in the urine (hematuria) Dark, cola-colored urine Swelling in the face, hands, feet, or abdomen (edema) High blood pressure Decreased urine output General feeling of fatigue or illness Fever, if infection is involved
Diagnostic & Treatment
Diagnosis Path: Urinalysis to detect hematuria, proteinuria, and cellular casts Blood tests to assess kidney function, such as serum creatinine and blood urea nitrogen (BUN) Serological tests for underlying immune or infectious causes Imaging studies like ultrasound to evaluate kidney size and structure Kidney biopsy, in certain cases, to confirm focal and segmental lesions and determine the precise nature of glomerular damage
Treatment Protocols: Medications to control blood pressure, such as ACE inhibitors or ARBs Immunosuppressive drugs if immune-mediated causes are identified Diuretics to manage edema Plasmapheresis in severe cases to remove harmful immune complexes Treating any underlying infections with antibiotics Monitoring kidney function regularly to assess response to treatment
