Acute Pyelonephritis I: Introduction01:27

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,...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
Nephrotic Syndrome I : Introduction01:24

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...
Renal Corpuscle01:20

Renal Corpuscle

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...
Cholecystitis01:20

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
Urinary Tract Calculi I: Introduction01:28

Urinary Tract Calculi I: Introduction

Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

Summary
This summary is machine-generated.

Chyluria, often linked to lymphatic abnormalities, can be caused by severe hyperlipidemia in nephrotic syndrome. This case report highlights successful treatment of chyluria and hyperlipidemia with corticosteroids and cyclophosphamide.

Area of Science:

  • Nephrology
  • Immunology
  • Gastroenterology

Background:

  • Chyluria involves abnormal lymph flow from intestines into the renal system.
  • Known causes include infections, malignancies, trauma, and lymphatic duct issues.
  • This case explores chyluria associated with nephrotic syndrome and microscopic polyangiitis.

Purpose of the Study:

  • To report a unique case of chyluria.
  • To investigate the underlying cause of chyluria in a patient with nephrotic syndrome and microscopic polyangiitis.
  • To evaluate the treatment efficacy of immunosuppressants on chyluria and hyperlipidemia.

Main Methods:

  • Clinical presentation and patient history.
  • Laboratory tests (including lipid profile, renal function).
  • Histological examination of kidney biopsy.
  • Radiological imaging to assess lymphatic system.
  • Treatment with corticosteroids and cyclophosphamide.

Main Results:

  • Patient presented with chyluria and severe hyperlipidemia secondary to nephrotic syndrome.
  • Microscopic polyangiitis was diagnosed.
  • Filarial, tuberculous, and lymphatic malformations were ruled out.
  • Treatment led to resolution of hyperlipidemia and chyluria.

Conclusions:

  • Microscopic polyangiitis can induce nephrotic syndrome, leading to severe hyperlipidemia and chyluria.
  • Immunosuppressive therapy (corticosteroids and cyclophosphamide) is effective in managing chyluria and hyperlipidemia in this context.
  • This case expands the differential diagnosis of chyluria beyond common causes.
