Lupus may be classified into several subtypes according to clinical features which include: systemic lupus erythematosus, cutaneous lupus erythematosus, drug-induced lupus, and neonatal lupus. Systemic lupus erythematosus (SLE) itself may be classified into several subtypes based on glomerulonephritis and dermatologic manifestation. SLE may be classified according to dermatologic manifestations into 4 subtypes: acute cutaneous lupus erythematosus (ACLE), subacute cutaneous lupus erythematosus (SCLE), chronic cutaneous lupus erythematosus (CCLE), and intermittent cutaneous lupus erythematosus (ICLE). SLE may be classified according to glomerulonephritis into 6 subtypes: minimal mesangial lupus nephritis (class I), mesangial proliferative lupus nephritis (class II), focal lupus nephritis (class III), diffuse lupus nephritis (class IV), lupus membranous nephropathy (class V), and advanced sclerosing lupus nephritis (class VI).
[[Lupus]] may be classified into several subtypes according to clinical features, including [[systemic lupus erythematosus]], [[cutaneous lupus erythematosus]], [[Drug-induced lupus erythematosus|drug-induced lupus]], and [[Neonatal lupus erythematosus|neonatal lupus]]. [[Systemic lupus erythematosus]] ([[SLE]]) itself may be classified into several subtypes based on [[Dermatology|dermatologic]] manifestations or [[glomerulonephritis]]. [[SLE]] may be classified according to [[Dermatology|dermatologic]] manifestations into 4 subtypes: acute cutaneous lupus erythematosus (ACLE), [[subacute]] cutaneous lupus erythematosus (SCLE), chronic cutaneous lupus erythematosus (CCLE), and intermittent cutaneous lupus erythematosus (ICLE). SLE may be classified according to [[glomerulonephritis]] into 6 subtypes: minimal mesangial lupus nephritis (class I), mesangial proliferative lupus nephritis (class II), focal lupus nephritis (class III), diffuse lupus nephritis (class IV), lupus membranous nephropathy (class V), and advanced sclerosing lupus nephritis (class VI).


==Classification==
==Classification==
Lupus may be classified into several subtypes according to clinical features which include:
* Systemic lupus erythematosus (SLE)
* Cutaneous lupus erythematosus (CLE)
* Drug-induced lupus
* Neonatal lupus
Based on this classification, SLE is a subtype of lupus that can be classified into different subclasses as well. CLE can be presented with or without systemic symptoms of the disease.


Systemic lupus erythematosus (SLE) may be classified into several subtypes based on glomerulonephritis and dermatologic manifestation.

Systemic lupus erythematosus, or SLE, is the most common form of lupus.
Discoid lupus erythematosus causes a skin rash that doesn't go away.
Subacute cutaneous lupus erythematosus causes skin sores on areas of the body exposed to the sun.
Neonatal lupus affects newborns.
Drug-induced lupus can be caused by certain medicines.
There are several types of lupus; in general, when the word lupus alone is used, reference is to systemic lupus erythematosus. different manifestion  Other types include:<ref name="Andrews">James, William; Berger, Timothy; Elston, Dirk (2005).

*Chronic cutaneous lupus erythematosus
**[[Discoid lupus erythematosus]], a skin disorder that causes a red, raised rash on the face and scalp. Discoid lupus occasionally (1–5%) develops into SLE.<ref>[http://www.skinsite.com/info_discoid_lupus_erythematosus.htm Discoid Lupus Erythematosus]</ref>

**Lupus erythematosus-lichen planus overlap syndrome
**Lupus erythematosus panniculitis (Lupus erythematosus profundus)
**Subacute cutaneous lupus erythematosus, which causes nonscarring skin [[lesions]] on patches of skin exposed to sunlight.<ref name="niams">{{cite web |url=http://www.niams.nih.gov/Health_Info/Lupus/default.asp |title=Handout on Health: Systemic Lupus Erythematosus |accessdate=2007-11-23 |month=August | year=2003 |work=The National Institute of Arthritis and Musculoskeletal and Skin Diseases |publisher=National Institutes of Health}}</ref>
**Tumid lupus erythematosus

*Neonatal lupus erythematosus, a rare disease affecting babies born to women with SLE, [[Sjögren's syndrome]], or sometimes no autoimmune disorder. It is theorized that maternal antibodies attack the fetus, causing skin rash; liver problems; low blood counts, which gradually fade; and heart block, leading to [[bradycardia]].<ref name="niams" />

Overview

Lupus may be classified into several subtypes according to clinical features, including systemic lupus erythematosus, cutaneous lupus erythematosus, drug-induced lupus, and neonatal lupus. Systemic lupus erythematosus (SLE) itself may be classified into several subtypes based on dermatologic manifestations or glomerulonephritis. SLE may be classified according to dermatologic manifestations into 4 subtypes: acute cutaneous lupus erythematosus (ACLE), subacute cutaneous lupus erythematosus (SCLE), chronic cutaneous lupus erythematosus (CCLE), and intermittent cutaneous lupus erythematosus (ICLE). SLE may be classified according to glomerulonephritis into 6 subtypes: minimal mesangial lupus nephritis (class I), mesangial proliferative lupus nephritis (class II), focal lupus nephritis (class III), diffuse lupus nephritis (class IV), lupus membranous nephropathy (class V), and advanced sclerosing lupus nephritis (class VI).

Classification

Classification of lupus based on clinical characteristics

Lupus may be classified into the following types based on clinical characteristics:[1]

Classification of SLE based on dermatologic manifestations

SLE may be further classified according to dermatologic manifestations into 4 subtypes:[1][2][3]

  • Acute cutaneous lupus erythematosus (ACLE)
  • Subacute cutaneous lupus erythematosus (SCLE)
  • Chronic cutaneous lupus erythematosus (CCLE)
  • Intermittent cutaneous lupus erythematosus (ICLE)
Subtypes Manifestation/subclass
Acute cutaneous lupus erythematosus (ACLE)
Subacute cutaneous lupus erythematosus (SCLE)
Chronic cutaneous lupus erythematosus (CCLE)
Intermittent cutaneous lupus erythematosus (ICLE)

Classification of SLE based on glomerulonephritis

SLE may be classified according to the degree of glomerulonephritis into 6 subtypes:[4][5][6]

Subtype Manifestation/subclass
Minimal mesangial lupus nephritis (class I)
Mesangial proliferative lupus nephritis (class II)
Focal lupus nephritis (class III)
Diffuse lupus nephritis (class IV)
  • Most common and most severe form
Lupus membranous nephropathy (class V) 
Advanced sclerosing lupus nephritis (class VI)
