Insights

A diabetic patient with multiple tumors developed a severe urinary infection and sepsis, leading to a fatal hyperglycemic hyperosmolar non-ketotic coma. Postmortem imaging revealed emphysematous pyelonephritis (EPN), a rare infection.

Area of Science:

  • Medicine
  • Pathology
  • Radiology

Background:

  • Diabetes mellitus is a significant risk factor for various infections.
  • Early detection and management of infections are crucial in diabetic patients.
  • Emphysematous pyelonephritis (EPN) is a rare but severe bacterial infection of the kidney.

Observation:

  • A diabetic woman presented with incidentally discovered tumors in the liver, kidney, and urinary bladder.
  • She initially refused surgery and was monitored for two months.
  • The patient was later found unconscious and diagnosed with urinary infection, sepsis, and hyperglycemic hyperosmolar non-ketotic coma.

Findings:

  • The patient experienced a rapid, fatal clinical course.
  • Postmortem computed tomography (CT) confirmed the presence of emphysematous pyelonephritis (EPN).
  • The case illustrates a rare, life-threatening infection in a patient with uncontrolled diabetes and potential underlying malignancy.

Implications:

  • This case underscores the critical need for vigilant infection management in diabetic individuals.
  • It may offer insights into the pathogenesis of EPN, particularly in the context of diabetes.
  • Prompt diagnosis and treatment of infections in diabetic patients can prevent severe complications and mortality.

Acute Pyelonephritis I: Introduction

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Diabetic Nephropathy

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...

Nephrons

The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma happens...

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
