Lupus nephritis (ln) is defined as glomerular immune complex disease that occurs in patients who meet american college of rheumatology for diagnosis of systemic lupus erythematosus (sle). Sle is a systemic autoimmune disease, most commonly involving the skin, kidneys, joints, heart, and serosal surfaces. Women are affected more than men (9:1), and sle is more common in african americans.
Immunological processes involving the urinary tract predominantly affect the renal glomerulus, the disease process results in glomerulonephritis. It means inflammation of glomeruli, which affects both kidneys equally. It is a type of kidney disease in which the part of kidney (glomeruli) that helps in filter waste and fluids from blood is damaged.
This report describes the renal pathology in three siblings with hereditarynephritis. All three cases showed combined features of chronicglomerulonephritis, pyelonephritis, and interstitial nephritis. These findings support the contention of krickstein,gloor, and balogh (1966) that the renal changes in hereditary nephritis are thoseof a mixed nephritis.

The glomerular pathology of lupus nephritis is the result of diverse immune insults which are probably of independent pathogenetic origins. Although lupus nephritis is looked upon as a classic example of immune complex-induced microvascular injury resulting from circulating dna double stranded polynucleotide antigens/anti-dna antibody complexes, other mechanisms, including in situ reactivity of free antibody with fixed antigens and the role of sensitized t-cells, are probably an important.
It’s harder to pump blood through the glomerulus when it’s all stuffed full of cells, so the glomerular filtration rate goes down (leading to oliguria). There are three main primary glomerular diseases that commonly present with nephritic syndrome: acute infectious (post-streptococcal) glomerulonephritis.

Some features are suggestive of lupus nephritis: hyaline thrombi and “wire loop” lesions (homogenous and “rigid” thickening of peripheral capillary loops due to subendothelial immune deposits), nevertheless, the only alteration considered by many authors as pathognomonic of lupus nephritis are the hematoxylin bodies: they are rounded, smudgy, lilac-staining structures, seen as cells with degenerated aspect; probably they represent degenerated nuclei and correspond to le cells.

Acute glomerulonephritis; glorulo -glomeruli, nephro -kidney, -itis -inflammation; is the sudden onset of inflammation of the glomeruli from infections originating from different parts of the body. Scarring on kidney tissues then occurs, leading to the decrease in ability of the kidney to filter the blood and produce urine.

So glomerulonephritis is inflammation of this glomerulus caused by some sort of immune reaction. Common predisposing factors are respiratory or skin infections or autoimmune diseases like lupus. These things cause an immune response in our systems that can come here into the nephron and damage the glomerulus.
Acute drug-induced interstitial nephritis, typically arises 15 days after exposure, non dosage related may be a delayed (type iv) hypersensitivity reaction, due to hapten like effect of drug, which binds to tubular epithelium, making it immunogenic.
