Intraglomerular monocyte infiltration and immune deposits in diffuse lupus glomerulonephritis
1Department of Pathology and Laboratory Medicine, St Paul's Hospital, Vancouver, Canada.
Summary
In lupus nephritis (LN), glomerular immune deposits and monocyte infiltration have opposing effects. This study found these two factors are inversely related, suggesting a complex interplay in kidney disease progression.
Area of Science:
- Nephrology
- Immunology
- Pathology
Background:
- Glomerular monocyte infiltration and immune deposits have contrasting prognostic values in lupus nephritis (LN).
- The relationship between these two pathological features in LN remains unclear.
Purpose of the Study:
- To investigate the correlation between glomerular monocyte infiltration and immune deposits in patients with diffuse proliferative lupus nephritis.
Main Methods:
- Analysis of 37 renal biopsy specimens from LN patients.
- Histological assessment of activity and chronicity indices.
- Semiquantitative scoring of glomerular immunoglobulin G (IgG) deposits and CD68+ monocyte infiltration (MOI).
Main Results:
- A significant inverse correlation was observed between IgG deposit scores and monocyte counts.
- A weaker but significant inverse correlation existed between the overall deposit index (DI) and MOI.
- Histological DI correlated positively with DI scored on immunolabeled sections.
Conclusions:
- The amount of glomerular immune deposits and the extent of glomerular monocyte infiltration are inversely related in lupus nephritis.
- This inverse relationship may have implications for understanding LN pathogenesis and prognosis.

01:29Acute Kidney Injury II: Pathophysiology
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...
01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...

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...
