OBJECTIVES: Commercial curcumin (CU), derived from food spice turmeric (TU), has
been widely studied as a potential therapeutic for a variety of oncological and
inflammatory conditions. Lack of solubility/bioavailability has hindered
curcumin's therapeutic efficacy in human diseases. We have solubilised curcumin
in water applying heat/pressure, obtaining up to 35-fold increase in solubility
(ultrasoluble curcumin (UsC)). We hypothesised that UsC or ultrasoluble turmeric
(UsT) will ameliorate systemic lupus erythematosus (SLE) and Sjögren's syndrome
(SS)-like disease in MRL-lpr/lpr mice. METHODS: Eighteen female MRL-lpr/lpr (6
weeks old) and 18 female MRL-MpJ mice (6 weeks old) were used. Female MRL-lpr/lpr
mice develop lupus-like disease at the 10th week and die at an average age of
17?weeks. MRL-MpJ mice develop lupus-like disease around 47?weeks and typically
die at 73?weeks. Six mice of each strain received autoclaved water only
(lpr-water or MpJ-water group), UsC (lpr-CU or MpJ-CU group) or UsT (lpr-TU or
MpJ-TU group) in the water bottle. RESULTS: UsC or UsT ameliorates SLE in the
MRL-lpr/lpr mice by significantly reducing lymphoproliferation, proteinuria,
lesions (tail) and autoantibodies. lpr-CU group had a 20% survival advantage over
lpr-water group. However, lpr-TU group lived an average of 16?days shorter than
lpr-water group due to complications unrelated to lupus-like illness. CU/TU
treatment inhibited lymphadenopathy significantly compared with lpr-water group
(p=0.03 and p=0.02, respectively) by induction of apoptosis. Average lymph node
weights were 2606±1147, 742±331 and 385±68?mg, respectively, for lpr-water,
lpr-CU and lpr-TU mice. Transferase dUTP nick end labelling assay showed that
lymphocytes in lymph nodes of lpr-CU and lpr-TU mice underwent apoptosis.
Significantly reduced cellular infiltration of the salivary glands in the lpr-TU
group compared with the lpr-water group, and a trend towards reduced kidney
damage was observed in the lpr-CU and lpr-TU groups. CONCLUSIONS: These studies
show that UsC/UsT could prove useful as a therapeutic intervention in SLE/SS.
