SLE is systemic autoimmune disease affecting mainly females in their reproductive age. It has different presentations & autoantibodies that have to be followed by specialists in Rheumatology & Immunology. It is wise to revise our Knowlege regularly to pickup the recent updates.

Objective
Our objective is to describe the
most relevant data on SLE that
emerged during the past year

5. Key features and organs involved in SLE
Antonis Fanouriakis et al. Ann Rheum Dis 2021;80:14-25
Systemic lupus
erythematosus (SLE) is
a chronic multisystem
auto-immune disease
with extremely variable
clinical manifestations.
, unpredictable course
and flares

6. Pathogenesis and novel therapies in SLE
Antonis Fanouriakis et al. Ann Rheum Dis 2021;80:14-25
Genetic and environmental interactions culminate into
aberrant regulation of both innate and adaptive immune
responses, with excessive production of IFN-α and
autoantibodies
B-cell
plasma cell
B–T-cell co-stimulation
IFNs
JAKs
cytokines

7. Pathogenesis
 Female predominance is poorly understood, suggesting the presence of
hormonal or X-linked genetic factors.
 New evidences suggest that sex-bias in SLE is likely related to epigenetically-
induced modifications in X linked immunity genes expression, especially in
B cells-driven autoimmunity
YU B, QI Y. et al Cell 2021; 184: 1790-803 e17
 The T helper 17 (Th17) pathway has been implicated in several aspects of
SLE disease pathogenesis including lupus arthritis, related cytokines, such as
IL-8 and IL-21 may become a potential therapeutic target in SLE
SIPPL N et al. Clin Exp Immunol 2021; 205: 44-52.

and activity. XIANG M et al. Sci Rep 2021; 11: 4707

11. Treat-to-target and remission
The Definitions Of Remission In SLE (DORIS) initiative was started in
order to provide a framework for defining remission as the ideal target of
SLE management.
The 2021 DORIS definition of remission in SLE includes:
Clinical SLEDAI=0 and Physician Global Assessment (PhGA) < 0.5
irrespective of serology; the patient may be on antimalarials, low-dose
GCs (prednisolone < 5mg daily) and /or stable immunosuppressives.
From the clinician’s perspective, the ideal treatment target for SLE has not
yet been found MUCKE J et al.Rheumatology (Oxford) 2021; 60: 4298-305
Patients and physicians may have different expectations of remission and
low disease activity states: the improvement of fatigue, joint pain and
quality of life (PROs) appear to be the treatment goals from the patient’s
perspective. DIETZ B et al. Arthritis Care Res (Hoboken) 2021; 73: 48- 54.

12. The 2021 DORIS definition of remission in SLE
 Clinical SLEDAI=0.
 Physician Global Assessment : < 0.5 (0 - 3).
 Irrespective of serology (anti-DNA, complement).
 The patient may be on antimalarials, low-dose glucocorticoids
(prednisolone ≤5 mg/day), and/or stable immunosuppressives
including biologics.

14. New therapies and therapeutic
strategies

15. Gradual corticosteroid withdrawal is safe in clinically quiescent
systemic lupus erythematosus
Data from patients with 2 consecutive years of clinically quiescent
disease were analysed to assess if gradual tapering of GCs was
associated with different rates of clinical flare and damage accrual in
comparison to low dose (5 mg/day) prednisone maintenance therapy.
All patients (n=102 in each group) were followed for 2 years.
Flare rate was lower in the withdrawal group both at 12 (17.6% vs. 29.4)
and 24 months (33.3% vs. 50%), and damage accrual was less frequent
in the withdrawal group.
Conclusion :GCs withdrawal is feasible in patients with clinically
quiescent SLE and it is not related to a significant incidence of flare.
TSELIOS K, GLADMAN DD, SU J, UROWITZ MB: Gradual glucocorticosteroid withdrawal is safe in clinically quiescent systemic
lupus erythematosus. ACR Open Rheumatol 2021; 3: 550-7

16. Concluding Remarks for Steroid Therapy
We should not being comfortable with patients being on high dose GCs for
extensive periods
Need to minimize GC exposure while still maintaining adequate control of
the disease
GCs withdrawal is feasible in patients with clinically quiescent SLE and it
is not related to a significant incidence of flare.
Possible strategies:
 Use of lower dose of steroids
IV pulse therapy followed by lower doses
Early introduction of concomitant immunomodulatory therapies

17. Lupkynis (voclosporin)

VOCLOSPORIN IN TREATMENT OF LUPUS NEPHRITIS (LN)
(AURORA study)
Voclosporin: a novel calcineurin inhibitor, works by blocking interleukin (IL)-2 expression
and T-cell mediated immune responses and stabilizing the podocyte in the kidney.
Renal response (RR) defined as UPCR of ≤ 0.5 mg/mg, eGFR ≥ 60 mL/min.

.
VOCLOSPORIN IN TREATMENT OF LUPUS NEPHRITIS (LN)
Conclusion
Voclosporin was efficacious in patients
with difficult to treat LN with no unexpected
safety signals.
Jan 2021(FDA) approved of the use of
Lupkynis (voclosporin) as the first oral
treatment developed specifically for adults
with active lupus nephritis in combination
with standard-of-care.

20. BENLYSTA (belimumab)

21. BENLYSTA (belimumab) for the treatment of lupus nephritis (Dec, 2020)
Belimumab selectively binds to B lymphocyte stimulator protein (BLyS)
, was approved on March 2011, by FDA as first targeted biological for the
treatment of SLE patients.
(BLISS-LN) study: multicenter trial of 448 patients with biopsy-proven,
active class III, IV, or V LN, who were treated with standard therapy
(mycophenolate mofetil or IV cyclophosphamide initial therapy
plus azathioprine subsequent therapy)
The addition of belimumab led to improved two-year renal response
rates compared with placebo .
Adverse effects were similar between groups.
December 2020, the (FDA) approved belimumab (Benlysta) to treat
adults with active lupus nephritis who are receiving standard therapy.

2. less glucocorticoid
administration
less damage long-term
3. Rapid reduction in proteinuria Rapid renal response
fewer LN flares

28. Tacrolimus (Prograf)
Recently, growing interest has been raised for calcineurin inhibitors,
especially in patients who do not achieve complete renal response to
standard treatments.
Tacrolimus, a calcineurin inhibitor, is considered as a promising treatment
option for LN.
A study on long term-safety and effectiveness of this drug in 1355
Japanese patients has recently provided interesting results.
In this large population of patients with LN, long-term tacrolimus
maintenance treatment over 5 years was well tolerated and effective.
The most frequent adverse drug reactions were infections, which
generally developed early in the treatment period
TAKEUCHI T, WAKASUGI N, UNO S, MAKINO H: Long-term safety and effectiveness of tacrolimus in patients with lupus
nephritis: 5-year interim post marketing surveillance study in Japan (TRUST). J Rheumatol 2021; 48: 74-81.

29. Combination Therapy with Rituximab and Belimumab
Combination therapy with rituximab and belimumab seems to be
promising treatment for refractory patients with good safety profile
A randomised, double-blind, placebo-controlled trial, 52 patients were
treated with RTX and 4 to 8 weeks later were randomly assigned (1:1) to
receive intravenous belimumab or placebo for 52 weeks.
At 52 week combination therapy significantly reduced serum anti-dsDNA
antibody levels and reduced risk for severe flare in patients with SLE that
was refractory to conventional therapy

Ann Intern Med 2021; 174: 1647-57.

30. Saphnelo (anifrolumab)

31. Saphnelo (anifrolumab) for SLE
The FDA Aug, 2021 has approved Saphnelo (anifrolumab) for adults with
moderate to severe (SLE) who are receiving standard therapy.
Anifrolumab, a human monoclonal antibody, binds to the type I IFN
receptor and blocks the biologic activity of type I IFN
The approval was based on data from three 52-week, multicenter,
randomized, double-blind, placebo controlled studies TULIP-1 and TULIP-2,
which evaluated the efficacy and safety of anifrolumab in adults with
moderate to severe SLE.
The frequency of herpes zoster was higher with anifrolumab than with
placebo
Saphnelo is supplied as a 2mL single-dose vial containing 300 mg via IV
infusion every 4 weeks
Eric F. Morand, M.B.,et al.N Engl J Med 2020; 382:211-221

33. SLE and COVID-19
 In SLE patients with COVID-19 only lupus nephritis resulted as a predictor
of severe to critical COVID19.
 None of the medications used to treat SLE was significantly associated
with the severity of the COVID-19 infection.
 Most patients with SLE and confirmed COVID-19 were able to produce and
maintain a serological response despite the use immunosuppressants.
COVID-19 vaccination seems to be well tolerated in SLE patients.
