Does Emflaza cause DMD?
While inflammation normally triggers healing processes in the body, the over-activation of the immune system promotes the breakdown of muscle cells and can speed the progression of DMD. Emflaza is a pro-drug, meaning that the therapy must be metabolized in the body into its active form.
Does Emflaza slow down the progression of DMD?
Once metabolized to its active form, Emflaza acts to suppress the immune system. The precise mechanism by which Emflaza slows the progression of DMD is unclear, but its effect is thought to be mediated by the suppression of the immune system, thereby reducing muscle damage.

What are some examples of therapeutic corticosteroid effects?
Examples include dexamethasone and betamethasone, two synthetic corticosteroids which dissociate glucocorticoid from mineralocorticoid activities through chemical modification of the basic corticosteroid structure. Although glucocorticoid effects are retained, many mineralocorticoid side effects are avoided. A different approach to selectivity has been taken with raloxifene, a nonsteroidal benzothiophene that is classified as a selective estrogen receptor modulator [ 52, 53 ]. In human studies, raloxifene appears to have tissue-specific estrogen-agonist or -antagonist activity which is putatively beneficial for bone mineral density and serum cholesterol.
What is the best treatment for DMD?
The mainstay of medical therapy for DMD is the corticosteroids prednisone and deflazacort. These are the only medications that have been shown to affect the clinical course, with a consensus that treatment with some corticosteroid regimen results in preservation of ambulation by up to 1 to 3 years. Their precise mechanism of their effect is unknown, but postulated effects include membrane stabilization, diminished fibrosis, and decreased inflammatory responses. A seminal randomized placebo-controlled trial of prednisone demonstrated that treatment with 0.75 mg/kg per day resulted in improved muscle strength by 6 months, whereas a dose twice that showed no additional benefit, with significantly more side effects. Deflazacort at an equivalent dose of 0.9 mg/kg per day has equivalent efficacy but a potentially a less pronounced side effect profile, with less weight gain. However, both drugs are associated with significant side effects, including obesity, gastrointestinal bleeding, osteoporosis (leading to increased vertebral body and long bone fracture, with the latter leading to a risk of fat embolism syndrome), short stature, delayed puberty, Cushingoid features, hypertension, cataracts, glaucoma, and emotional lability. Alternative regimens have been utilized in an effort to minimize side effects, including dosing on a schedule of 10 days on/10 days off or for the first 10 days a month. A small study of weekend dosing at 10 mg/kg per week divided on weekend days suggested efficacy roughly equivalent to daily dosing in terms of efficacy, but showed no significant decrease in side effects. These different regimens have not been well characterized in head-to-head clinical trials, but the ongoing NIH-sponsored multicenter, multiyear FOR-DMD randomized double-blinded trial will likely answer outstanding questions regarding relative efficacy and side effects among these alternate regimens.
What are the long term effects of steroid treatment?
However, long-term cardiovascular effects of steroid treatment include obesity, hypertension, and cardiac hypertrophy. 78 The effects of steroid treatment on cardiac function have also been studied. Markham et al looked at patients with DMD who were 7.5 to 12 years old and were treated with either prednisone or deflazacort (n = 14) or with no steroids at all ( n = 23). The FS decreased from 35.5% to 26.0% in the untreated group, whereas it remained unchanged (36%–34%) in the steroid-treated group. The steroid-treated patients’ hearts also did not dilate as much as those of untreated patients. There were no significant differences in blood pressure between the two groups. Thus, steroids, started before there was any evidence of decreased cardiac function, delayed the onset of ventricular dysfunction in these patients. 79 In an earlier study by the same group, untreated subjects 10 years old or younger were 4.4 more times likely to have FS of less than 28%. Untreated subjects older than 10 years were 15.2 times more likely to have decreased FS compared with steroid-treated subjects. There was no difference in FS between the prednisone and deflazacort groups (see also Chapter 19 ).
Is deflazacort the same as prednisolone?
Deflazacort,123 an oxazoline derivative of prednisolone introduced in 1969, initially was thought to be as effective as prednisolone while inducing fewer adverse effects, but there is the issue of the real equivalence ratio compared with prednisolone, 124 and deflazacort has not represented a major breakthrough. Knowledge about the mechanisms of glucocorticoids (with the hypothesis that transrepression and transactivation lead, respectively, to predominantly beneficial effects and adverse effects; see earlier) led to the development of selective glucocorticoid receptor agonists. 125 However, the underlying hypothesis was challenged, 15 and the effect of a selective glucocorticoid receptor agonist was disappointing 16; as yet no such drug has entered the market.
Do corticosteroids slow down the progression of dystrophy?
Corticosteroids are the only medication shown to slow the rate of progression of weakness in randomized controlled trials of large numbers of patients ( Manzur et al., 2008). Both prednisolone and deflazacort have been demonstrated to improve strength in children with Duchenne muscular dystrophy (Brooke et al., 1987; Mendell et al., 1989; Fenichel et al., 1991; Griggs et al., 1993; Moxley et al., 2005 ). There is insufficient evidence to comment on any possible benefit in patients with other forms of dystrophy. Personal experience suggests that many patients with various dystrophies (particularly dysferlinopathy, calpainopathy, and FSHD) who are misdiagnosed with polymyositis and treated with corticosteroids have not had apparent improvement. However, we do not know whether corticosteroids might slow the rate of progression of the disease. It seems reasonable, particularly with the childhood-onset sarcoglycanopathies and fukutinopathies, that corticosteroids may be beneficial.

Dosage
The usual starting dose of the corticosteroids prednisone or prednisolone for ITP patients is .5 to 2 milligram (mg)/ kilogram (kg) for two to four weeks before tapering, depending on the response. 5 One kilogram is equal to 2.2 pounds; based on this, body weight would be divided by 2.2 to determine the starting dosage.
Side Effects
A partial list of the possible side effects includes: cataracts, gastrointestinal discomfort, osteoporosis, obesity, moon face, hypertension (high blood pressure), diabetic metabolism (blood sugar changes), sleep disturbances (insomnia), psychiatric syndromes (mood changes), delayed wound healing, atrophy (muscle wasting, including the heart muscle), potassium loss, and changes in the skin.
Predicting Success
While 50 to 90 percent of ITP patients see a rise in platelet counts with an initial high dose of corticosteroids, only 10 to 30 percent have a durable remission, and some of those may require further treatment. 4
