There is no effective treatment for scleroderma
so far. However, after intervention, some cases are stable without progression
of illness or even relieved
1. General management includes quitting smoking,
strengthening nutrition, keeping warm and avoiding mental stimulation.
2. Vasoactive drugs are used to dilate the
vessels, reduce blood viscosity and improve microcirculation.
(1) Danshen Injection
Each milliliter of Danshen injection is
equilavent to 2 grams of the crude drug in the amount of active ingredient. Add
8-16 milliliter of the injection into 500 ml of low Molecular Dextran and give
the solution by intravenous drip infusion once daily, 10 times as a treatment
course. And the therapy can be used either continuously or intermittently.
Studies prove that Danshen demonstrates a significant inhibition on fibroblasts
and its collagen synthesis in the skin. Clinically, Danshen shows some effect
on dermatosclerosis, difficulty in opening mouth and swallowing, joint
stiffness and Raynaud’s phenomenon. Patients with bleeding tendency and kidney
dysfunction should not use this therapy.
(2) Vasodilators
Nifedipine controlled-release tablet, 20 mg
bid;
Amlodipine, effect similar to nifedipine
but longer half-life, 5-10mg per day, administered at draught;
Prazosin, added to amlodipine in severe
cases with necrotic tendency, 0.5 mg initially, tid or qid, adding up to 1-2mg
if necessary, tid or qid;
Guanethidine, 12.5 mg/d at the beginning
and gradually adding up to 25 mg/d, then 37.5mg/d three weeks later, effective
to 50% of Raynaud’s phenomenon.
(3) Methyldopa, 250mg, tid, capable of
inhibiting Raynaud’s syndrome.
(4) Dipyridamole and low dose of aspirin, both
having the ability of anti-platelet aggregation and capable of being taken
orally.
3. antifibrotic agents
(1) Glucocorticoid
Glucocorticoid is effective for
inflammation, edema and joint discomfort in early stage of SSc. Patients are
usually recommended to orally take prednisone 30-40 mg per day for several
weeks and then slowly reduce to the maintenance dose of 5-10mg per day. But it
is contradicted to patients of advanced stage, especially those with nitremia,
for glucocorticoid may contribute to renovascular obliteration in those
patients.
(2) Other Immuno-suppressive agents
Choices of this kind of drugs include
azathioprine, chlorambucil, cyclophosphamide, etc., which have curative effect on
joint, skin and kidney lesions. When in combined therapy with glucocorticoid
(GC), their effect is improved and the dose of GC can be decreased.
3. Other Symptomatic Treatments
Patients who suffer from reflux esophagitis
should have more meals a day but less food at each and stay in an erect or
semi-reclining position after meals. Ranitidine, famotidine and proton pump
inhibitors like omeprazole are used to reduce the acid. As for dysphagia,
domperidone is recommended to improve gastric dynamics.
4. Physical Therapies
Physical therapies include audio frequency
electrotherapy, massage and heating bath, etc. Audio frequency electrotherapy
is helpful in softening the skin, improving the nutrition of tissue, and
promoting healing of the ulcers. Phototherapy can improve the symptoms caused
by thickening of the skin.
5. Other treatments include vein block
therapy, vitamin E, phosphoesterases complex and propionate testerone, etc.,
which can be used cooperatively with the drugs mentioned before. These years,
endothelin receptor antagonist (EDRA) and transforming growth factorβ1(TGFβ1) per os have been observed effective to treat pulmonary arterial
hypertension abroad. Transplantation of CD34+ sorted peripheral hemopoietic
stem cells has been put into clinical practice.
