Clinical Trial Summary
Recurrent hemarthrosis results in synovitis and destructive arthropathy in hemophilic
patients. Prophylactic replacement, physical therapy, cyclooxygenase-2 (COX-2) inhibitors,
corticosteroids, and radionucleotide synovectomy are some of the typical modalities used in
the managements hemophilic synovitis and arthropathy. In clinical practice, the choice of
non-steroidal anti-inflammatory drugs (NSAIDs) also needs to take into consideration the risk
for cardiovascular events and should be used at the lowest effective dose and for the
shortest duration.This study will investigate the safety and efficacy of Shea nut oil for the
treatment of hemophilic arthropathy.
Description:
Hemophilia is an X-linked recessive bleeding disorder caused by a deficiency of coagulation
factor VIII (hemophilia A) or IX (hemophilia B). Severe hemophilia patients may have frequent
spontaneous bleeding episodes such as joint and muscle bleeding. Repeated joint bleeding
leads to chronic synovitis, cartilage damage and bony destruction, which is associated with
range of motion (ROM) limitation, pain, muscle atrophy, functional impairment and poor
quality of life. Around 80% of all spontaneous joint bleeds occur in the ankles, knees and
elbows. Hemophilic arthropathy is a multifactorial event and there is evidence to suggest
that iron may play a major role with release of cytokines such as Interleukin-1,
Interleukin-6, and tumor necrosis factor-α (TNF-α) eading to chronic proliferative synovitis,
hypervascularity, and progressive arthropathy . Prophylactic replacement , physical therapy,
COX-2 inhibitors , corticosteroids, and radionucleotide synovectomy are some of the typical
modalities used in the managements hemophilic synovitis and arthropathy. The onset of joint
bleedings in severe hemophilia occurs approximately 23 months of age and arthropathy could be
marked in adolescents or young adults. Some hemophilia patients may either not be good
candidates for surgery or may prefer not to have surgery. The traditional Africans have used
African Shea tree and shea nuts oil extracts to treat arthritis. Shea nut oil contains are a
mixture of fatty acid and cinnamic acid esters of such triterpene alcohols as α-amyrine,
β-amyrine, butyrospermol, lupeol and to aminor extent, sterols, aliphatic alcohols, and
karitene. Triterpene alcohols such as lupeol and α/β-amyrine have been shown to possess
anti-inflammatory effects, especially in their esterified forms. In 1998, US Food and Drug
Administration approved shea nut oil as a safe food additive. The shea nut oil used in this
trial is a patented concentrate containing approximately 50% triterpenes derived from the
seed of the shea tree, Vitellaria paradoxa. The most abundant triterpenes in shea nut oil
areα-amyrin(54.6%), β-amyrin(12.3%), Lupeol(17%) plus their dihydro-derivatives. Cheras et
al. reported that shea nut oil extract treatment over the 15 weeks of their random
double-blind study in upper quartile of 89 osteoarthritis patients was effective in
decreasing inflammation marker TNF-α (23.9% vs 6%, treatment vs placebo) and cartilage
degradation marker C-terminal crosslinked telopeptide type II collagen (CTX-II) (28.7% vs an
increase of 17.6%, treatment vs placebo). Chen and his colleagues carried out a 16-week study
in 33 patients with osteoarthritis of knee joint and found shea nut oil was effective in
increasing activity and thickness of vastus medialis, and decreasing pain and stiffness of
knee joint. Late stage of hemophilic arthropathy is characterized by advanced cartilage
degeneration and joint destruction. These effects on cartilage and subchondral bone are
degenerative and inflammatory in nature, similar to the changes in osteoarthritis. Management
of chronic hemophilic arthropathy is difficult. NSAIDs have been used with caution in
patients with bleeding disorders because of their inhibition of platelet function and
gastrointestinal side effects. In clinical practice, the choice of NSAIDs also needs to take
into consideration the risk for cardiovascular events and should be used at the lowest
effective dose and for the shortest duration. This study will investigate the safety and
efficacy of Shea nut oil for the treatment of hemophilic arthropathy.
