Overview
There is no established system for the classification of [disease name].
OR
[Disease name] may be classified according to [classification method] into [number] subtypes/groups: [group1], [group2], [group3], and [group4].
OR
[Disease name] may be classified into [large number > 6] subtypes based on [classification method 1], [classification method 2], and [classification method 3]. [Disease name] may be classified into several subtypes based on [classification method 1], [classification method 2], and [classification method 3].
OR
Based on the duration of symptoms, [disease name] may be classified as either acute or chronic.
OR
If the staging system involves specific and characteristic findings and features: According to the [staging system + reference], there are [number] stages of [malignancy name] based on the [finding1], [finding2], and [finding3]. Each stage is assigned a [letter/number1] and a [letter/number2] that designate the [feature1] and [feature2].
OR
The staging of [malignancy name] is based on the [staging system].
OR
There is no established system for the staging of [malignancy name].
Classification
The Renal Pathology Society/International Society of Nephrology (RPS/ISN) classification:[1][2][3][4][5][6]
Minimal mesangial lupus nephritis (class I)
Mesangial proliferative lupus nephritis (class II)
- Microscopic Hematuria
- Proteinuria
- Hypercellularity in mesangium[1]
- Light microscopy shows subendothelial deposits or segmental scars[1]
- Immunofluorescence shows subepithelial or subendothelial deposits
- Good prognosis
Focal lupus nephritis (class III)
- Less than 50% glomeruli involved
- Hematuria
- Proteinuria
- Hypertension
- Crescent formation
- Uniform involvement on immunofluorescence[1][7]
- Subendothelial immune and mesangial deposits on electron microscopy[1][8].
Subclasses on the basis of inflammatory activity of the lesions:
- Class III (A) called focal proliferative lupus nephritis: Just active lesions.[8][9]
- Class III (A/C) called focal proliferative and sclerosing lupus nephritis: Active and chronic lesions[9]
- Class III (C) called focal sclerosing lupus nephritis: Chronic inactive lesions with scarring.
Diffuse lupus nephritis (class IV)
- More than 50% glomeruli involved
- Proteinuria
- Hematuria
- Nephrotic syndrome
- Hypocomplementemia
- Increased anti-DNA antibodies
- Proliferative, necrotizing lesions
- Crescent formation
- Glomerular capillary wall thickening
- Monocytes, suppressor/cytotoxic T cells may be seen
- Subendothelial deposits on electron microscopy
Subclasses on the basis of involvment of affected glomeruli: Segmental (S) or global (G) and by the inflammation
- Class IV-S (A), class IV-S with active lesions called diffuse segmental proliferative nephritis.
- Class IV-G (A), class IV-G associated with active lesions called diffuse global proliferative nephritis.
- Class IV-S (A/C),associated with active and chronic lesions called diffuse segmental proliferative and sclerosing nephritis.
- Class IV-G (A/C), class IV-G with active and chronic lesions called diffuse global proliferative and sclerosing nephritis.
- Class IV-S (C), associated with chronic inactive lesions with scars called diffuse segmental sclerosing lupus nephritis.
- Class IV-G (C), class IV-G with chronic inactive lesions with scars called diffuse global sclerosing lupus nephritis
Lupus membranous nephropathy (class V)
- Nephrotic syndrome
- Microscopic hematuria
- Hypertension
- Light microscopy shows diffuse glomerular capillary wall thickening
- Immunofluorescence or electron microscopy shows subepithelial immune depositson
- May present no SLE features/Lab findings
Advanced sclerosing lupus nephritis (class VI)
- Proteinuria
- Dull urine sediment
- Greater than 90 percent of glomeruli involvement.
- Presence of all advanced stages of chronic class III, IV, or V lupus nephritis.
OR
- [Disease name] may be classified according to [classification method] into [number] subtypes/groups:
- [Group1]
- [Group2]
- [Group3]
- [Group4]
OR
- [Disease name] may be classified into [large number > 6] subtypes based on:
- [Classification method 1]
- [Classification method 2]
- [Classification method 3]
- [Disease name] may be classified into several subtypes based on:
- [Classification method 1]
- [Classification method 2]
- [Classification method 3]
OR
- Based on the duration of symptoms, [disease name] may be classified as either acute or chronic.
OR
- If the staging system involves specific and characteristic findings and features:
- According to the [staging system + reference], there are [number] stages of [malignancy name] based on the [finding1], [finding2], and [finding3]. Each stage is assigned a [letter/number1] and a [letter/number2] that designate the [feature1] and [feature2].
OR
- The staging of [malignancy name] is based on the [staging system].
OR
- There is no established system for the staging of [malignancy name].
