CHAPTER II
LITERATURE REVIEW
2.1. Definition
Systemic lupus erythematosus (SLE) is a rheumatic disease characterized by
autoantibody directed against self-antigens, immune complex formation, and
immune deregulation, resulting in damage to essentially any organ. hildhood S
L E generally presents bet!een the ages of " and #$ years, !ith girls out
numbering boys "%# '. n #-*+ of SLE patients the diagnosis is made for thefirst time in childhood &*-'. he disease can affect any organ but the most
freuent are the /idneys, s/in, blood 0essels and cells, 1oints, heart and SLE
ner0ous system.
2.2. Epidemiology
2ediatric SLE (pSLE) represents approximately #$-* + of all SLE patients.
t is more common in females than in males, !ith a female to male ratio 0arying
from *.3%# to %#, depending on the study. he incidence of the disease 0aries
according to different ethnic groups. SLE is more common in 4frican-4merican
females. 5carty 67 etc. reported the annual incidence of SLE is t!o and half
times more in 4frican-4merican females than that in !hite females. 4lso in
8riental population in 9orth 4merica, the disease appears to be aggressi0e and is
associated !ith a higher mortality. 4ccording to a sur0ey conducted in t!o
decades ago in Shanghai, the pre0alence of the disease is around : per #,
people and ##3 per #, in female population. t is estimated that there are
one million patients in hina. ;oth genetic factors and sex hormone are
contributed to the de0eloping of the disease. f a family member has SLE, the
li/elihood of SLE increases !ith approximately 3 + for identical t!ins and $+
for other first-degree relati0es.

2.3. Etiopatogene!i!
n SLE, there is mar/ed disturbance in immune regulation. hese
abnormalities may ha0e arisen from genetic, en0ironmental and hormonal factors.
he exact mechanism of interplay of these combined effects is still un/no!n.

9D423, *, ", , 2?), 694 repairs (=E#), adherence of infl
ammatory cells to the endothelium (>45), and tissue response to in1ury
(?L?#, ?L?3). hese findings highlight the importance of oll-li/e receptor
(L=) and type # interferon (D9) signalling path!ays. Some of the genetic loci
may explain not only the susceptibility to disease but also its se0erity. Dor
instance, S4", a genetic ris/ factor for rheumatoid arthritis and SLE, is
associated !ith se0ere SLE. 8ne of the /ey components of these path!ays is
9D423, !hich has been implicated in at least six autoimmune disorders,
including SLE.
*. Epigenetic effects
he ris/ for SLE may be influenced by epigenetic effects such as 694
methylation and post-translational modifications of histones, !hich can be either
inherited or en0ironentally modified. Epigenetics refers to inherited changes in
gene expression caused by mechanisms other than 694 base seuence changes.
he most !ell understood type of epigenetic factor is 694 methylation, !hich
plays a role in a 0ariety of human processes, such as chromosome inacti0ation
and certain cancers. 2re0ious research has also implicated the importance of
694 methylation in SLE. 6ifferences in the methylation status of genes may
explain, at least in part, the discordance obser0ed in some identical t!ins that are
discordant for SLE. Epigenetic mechanisms may represent the missing lin/
bet!een genetic and en0ironmental ris/ factors.
3. En0ironmental factors
andidate en0ironmental triggers of SLE include ultra0iolet light,
demethylating drugs, and infectious or endogenous 0iruses or 0iral li/e elements.
Sunlight is the most ob0ious en0ironmental factor that may exacerbate SLE.
EpsteinA;arr 0irus (E;F) has been identified as a possible factor in the
de0elopment of lupus. E;F may reside in and interact !ith ; cells and promotes

interferon a(D9a) production by plasmacytoid dendritic cells (p6s), suggesting
that ele0ated D9a in lupus may be at least in part due to aberrantly controlled
chronic 0iral infection. t is !ell established that certain drugs induce
autoantibodies in a significant number of patients, most of !hom do not de0elop
signs of an autoantibody associated disease. 80er # drugs ha0e been reported
to cause drug-induced lupus (6L), including a number of the ne!er biologics
and anti0iral agents. 4lthough the pathogenesis of 6L is not !ell understood, a
genetic predisposition may play a role in the case of certain drugs, particularly
those agents that are metabolised by acetylation such as procainamide and
hydralazine, !ith disease more li/ely to de0elop in patients !ho are slo!
acetylators. hese drugs may alter gene expression in 6" cells by inhibiting
694 methylation and induce o0erexpression of LD4-# antigen, thus promoting
autoreacti0ity.
". Cormonal factors
n murine models, addition of oestrogen or prolactin can lead to an
autoimmune phenotype !ith an increase in mature high affinity autoreacti0e ;
cells. 8ral contracepti0e use in the 9urses Cealth Study !as associated !ith a
slightly increased ris/ of de0eloping SLE (relati0e ris/ #. compared to ne0er
users). his poses important uestions pertaining to the use of oestrogens for oral
contraception or as hormone replacement therapy in postmenopausal !omen.
Bhile it is clear that hormones can influence autoimmune de0elopment in murine
models, the use of oral contracepti0es does not increase disease fl ares in !omen
!ith stable disease (Sanchez->uerrero et al *$). 2regnancy may cause in some
cases a lupus flare, but this is not due to an increase in oestradiol or progesterone@
infact, the le0els of these hormones are lo!er in the second and third trimester for
SLE patients in comparison !ith healthy pregnant !omen.

2.%. Patogene!i! and patopy!iology
mmune responses against endogenous nuclear antigens are characteristic of
SLE. 4utoantigens released by apoptotic cells are presented by dendritic cells to
cells leading to their acti0ation. 4cti0ated cells in turn help ; cells to produce
antibodies to these self constituents by secreting cyto/ines such as interleu/in #
(L#) and L*3 and by cell surface molecules such as 6"L and L4-". n
addition to this antigen-dri0en cell-dependent production of autoantibodies,
recent data support cell-independent mechanisms of ; cell stimulation 0ia
combined ; cell antigen receptor (;=) and L= signalling. h e pathogenesis
of SLE in0ol0es a multitude of cells and molecules that participate in apoptosis,
innate and adapti0e immune responses (table #). ncreased amounts of apoptosis
related endogenous nucleic acids stimulate the production of D9a and promote
autoimmunity by brea/ing self tolerance through acti0ation of antigen presenting
cells (figure 3). 8nce initiated, immune reactants such as immune complexes
amplify and sustain the inflammatory response.

4utoantibody-mediated tissue in1ury has been implicated in neuropsychiatric SLE
(92SLE), !here antibodies reacting !ith both 694 and glutamate receptors on
neuronal cells can mediate excitotoxic neuronal cell death or dysfunction. Locally
produced cyto/ines, such as D9a and tumour necrosis factor (9D), contribute
to aff ected tissue in1ury and infl ammation. h ese mediators, together !ith the
cells producing them (macrophages, leucocytes, dendritic cells and lymphocytes),
are the sub1ect of in0estigation as potential therapeutic targets in lupus. =ecent
studies ha0e also highlighted the role of locally expressed factors for the
protection of tissues under immune attac/. Dor example, defects in /alli/reins
may 1eopardise the ability of lupus /idneys to protect themsel0es from in1ury,
26-#-ligand do!n-regulates the acti0ity of the infi ltrating lymphocytes, and
impaired regulation of complement amplifi es 0ascular in1ury. Fascular damage in
SLE has recei0ed increased attention in 0ie! of its relationship !ith accelerated
atherosclerosis. Comocysteine and proinflammatory cyto/ines, such as D9a,
impair endothelial function and decrease the a0ailability of endothelial precursor
cells to repair endothelial in1ury. 2ro-inflammatory high density lipoproteins
(C6L) and a dysfunction of C6L mediated by antibodies ha0e also been
implicated in defecti0e repair of endothelium. 5oreo0er, pathogenic 0ariants of
45 (immuno-tyrosine acti0ation motif ) alter its binding to 45-#
(intercellular adhesion molecule #) and may increase the adherence of leucocytes
to acti0ated endothelial cells. mpaired 694 degradation as a result of mutations
of the 3H repair exonuclease # (=E#), and increased accumulation of single
stranded 694 deri0ed from endogenous retroelements in endothelial cells, may
acti0ate the D9-stimulatory 694 response and direct immune mediated in1ury to
the 0asculature.

an unpredictable course. he dynamic nature of the disease often ma/es its
diagnosis challenging. 4lthough the 4= classification criteria may also be used
as a diagnostic aid, there are se0eral ca0eats in their use for diagnostic purposes.
hese criteria !ere de0eloped and 0alidated for the classification of patients !ith
a longstanding established disease and may exclude patients !ith early disease or
disease limited to a fe! organs. hus, in spite of their excellent sensiti0ity
(NI$+) and specifi city (N$+) for patients !ith established disease, their
sensiti0ity for patients early in the disease may be significantly lo!er. Some
systems are o0errepresented@ the mucocutaneous manifestations, for example, are
represented !ith four criteria (photosensiti0ity, malar rash, discoid lesions, and
oral ulcers). 4ll features included in the classifi cation criteria are contributing
eually !ithout any !eight based upon sensiti0ity and specifi city for each
indi0idual criterion. hus, studies ha0e sho!n and experience supports that
criteria such as ob1ecti0e e0idence of renal disease (significant proteinuria, acti0e
urine sediment or renal biopsy !ith e0idence of lupus nephritis), discoid rash, and
cytopenias are more useful in establishing the diagnosis of lupus than the other
criteria. ;ecause SLE is a disease !hose course is typified by periodic

4ssessing disease acti0ity in SLE is crucial to the physician as it forms the
basis for treatment decisions. 6isease acti0ity needs to be distinguished from
damage as this has important implications for the long term prognosis and the
appropriate treatment. Se0eral 0alidated global and organ specific acti0ity indices
are !idely used in the e0aluation of SLE patients (Jro!itz and >ladman #I).
hese include the European onsensus Lupus 4cti0ity 5easure (EL45), the
;ritish sles Lupus 4ssessment >roup Scale (;L4>), the Lupus 4cti0ity ndex
(L4), the 9ational nstitutes of Cealth SLE ndex Score (SS), the Systemic
Lupus 4cti0ity 5easure (SL45), and the SLE 6isease 4cti0ity ndex
(SLE64). hese indices ha0e been de0eloped in the context of long term
obser0ational studies and ha0e been sho!n to be strong predictors of damage and
mortality, and reflect change in disease acti0ity. 5oreo0er, they ha0e been
0alidated against each other. Be recommend the use of at least one of these
indices for monitoring of disease acti0ity. n our experience the EL45 and the
SLE64 (table 3) are more con0enient for use in daily practice. omputerised
clinical charts that compute se0eral disease acti0ity indices simultaneously ha0e
been de0eloped. Existing disease acti0ity indices ha0e important limitations !hen
used in the context of clinical trials. Dor clinical trials, composite end points and

5ucocutaneous in0ol0ement is almost uni0ersal in SLE !ith both lupus-
specifi c and non-specific lesions (table $). Lupus specific lesions can be further
classified as acute, subacute, and chronic lesions.
4. 4cute rashes-malar rash.
he classic lupus MbutterflyH rash presents acutely as an erythematous,
ele0ated lesion, pruritic or painful, in a malar distribution, commonly
precipitated by exposure to sunlight. he rash may last from days to
!ee/s and is commonly accompanied by other infl ammatory
manifestations of the disease. he acute butterfly rash should be
differentiated from other causes of facial erythema such as rosacea,
seborrhoeic, atopic, and contact dermatitis, and glucocorticoid induced
dermal atrophy and flushing. 8ther acute cutaneous lesions include
generalised erythema and bullous lesions. he rash of acute cutaneous
lupus erythematosus can be transient and heal !ithout scarring, although
persistently acti0e rashes may result in permanent telangiectasias.
;. Subacute rashes.
Subacute cutaneous lupus erythematosus (SLE) is not uniformly

!ith SLE may present !ith annular or psoriasi form s/in lesions, and
this is strongly associated !ith anti-=o (SS-4) and anti-La (SS-;)
antibodies. 2atients !ith SLE ha0e a high incidence of photosensiti0ity
and in rare instances can present !ith erythema multiforme-li/e lesions
(=o!ellHs syndrome). SLE lesions begin as small, erythematous, slightly

scaly discoid lesions must also be diff erentiated from psoriasis.
6. 8ther rashes.
Lupus profundus presents as a firm nodular lesion !ith or !ithout an

4lopecia defined as exaggerated hair loss occurs in most SLE patients. t
may in0ol0e the scalp, eyebro!s, eyelashes, beard, and body hair.
Scarring alopecia is a complication of discoid lupus that typically aff ects
the scalp. MLupus hairH is characterised by thin hair that easily fractures. t
usually occurs along the frontal hairline, is associated !ith disease
acti0ity, and gro!s bac/ normally as the disease subsides.D. 2hotosensiti0ity.
2hotosensiti0ity is defi ned as the de0elopment of a rash aft er exposure to
ultra0iolet (JF) ; radiation coming from sunlight or fl uorescent lights. t
occurs in A#+ of SLE patients. Some patients are also sensiti0e to
JF4 radiation (emitted from photocopiers or some light bulbs), and may
e0en be sensiti0e to the 0isible light spectrum. 9ot all photosensiti0e
