Clinical Case Reports
|March 19, 2020
Summary
Systemic lupus erythematosus and Sjögren's syndrome can cause kidney damage. Treatment with prednisone stabilized tubulointerstitial lesions, but withdrawal led to progression into glomerular lesions.
Area of Science:
- Nephrology
- Rheumatology
- Autoimmune Diseases
Background:
- Systemic lupus erythematosus (SLE) and Sjögren's syndrome are autoimmune conditions that can affect multiple organs, including the kidneys.
- Kidney involvement in these diseases often manifests as lupus nephritis or secondary Sjögren's syndrome-related kidney disease.
Observation:
- A young woman with SLE and Sjögren's syndrome presented with tubulointerstitial lesions on renal biopsy.
- Initial treatment with prednisone resulted in clinical stability.
Findings:
- Upon prednisone withdrawal, a repeat renal biopsy demonstrated a significant transformation of the kidney pathology.
- The initial tubulointerstitial lesions converted into active glomerular lesions, indicating disease progression.
Implications:
- This case highlights the potential for rapid and severe renal pathology conversion in patients with co-existing SLE and Sjögren's syndrome.
- It underscores the importance of vigilant monitoring and potentially sustained immunosuppressive therapy even after initial stabilization.
- Understanding these disease dynamics is crucial for optimizing treatment strategies in autoimmune kidney diseases.

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...

01:24Nephrotic Syndrome I : Introduction
412
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...

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

01:10Nephrons
6.0K
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...
