walking ability at average of 11.8 years, compared
to 10.5 years in untreated group |

| 2000 |

at 0.9 mg/kg/day for a year |
at 1 year, two treated groups had same degree
of better motor function than untreated |
at 9 months, average weight increase in deflazacort
group was 5 percent; in prednisone group, was
18 percent |
| 2001 |
prednisone or prednisolone at 0.3, 0.75 and
1.5 mg/kg/day for 6 months (pooled results of
1989, 1991, 2001 studies) |
improved ability to rise from floor, time
to walk 9 meters (30 feet); 0.75 mg group showed
more benefit than 0.3 mg group, but 1.5 mg group
did not show additional benefit |
weight gain, fat redistribution and behavioral
changes in boys treated with 0.75 mg/kg/day
in two studies; 0.3 mg/kg/day group did not
differ in fat distribution from untreated in
one study |
| 2001 |
prednisone at 0.75 mg/kg/day for average of
10 years; dose decreased over time |
average age of loss of walking was 14.5 years,
compared to expected loss of walking at 8.8
to 10.5 years |

compared to untreated |
| 2002 |

alternating with 10 days off drug for 4 to 5+
years |
improvement in ability to rise from floor,
hop, jump, and run without waddle compared to
untreated |
did not see abnormal weight gain, bone loss
or other signs of toxicity |
| 2002 |
prednisone at 5 mg/kg/day Fridays and Saturdays

function
10 of 21 treated boys stopped walking, compared
with all 12 untreated boys
|
dose had to be decreased to average of
.59 mg/kg/day at age 18 because of side effects
cataracts,
below-average height in treated group
|

1 mg/kg/day for average of 4.5 years, with calcium
and sometimes vitamin D |
|
10 out of 25 treated boys developed spinal
(vertebral) fracture |
| 2004 |
European Neuromuscular Centre (ENMC) publishes
standards for use of corticosteroids in DMD |
evidence for use of daily steroids in DMD
established; monitoring, minimizing, treating
side effects necessary; alternatives to daily
steroids should be tested against daily steroids
in large trials; cardiac and bone protection
studies should be planned; quality of life should
be assessed |
|
| 2005 |
American Academy of Neurology publishes guidelines
for corticosteroids in DMD |
prednisone at 0.75 mg/kg/day is optimal, but
dosages as low as 0.3 mg/kg/day still have benefit;
deflazacort at 0.9 mg/kg/day can be substituted
for prednisone;
benefits and side effects need monitoring;
if excessive weight gain occurs, dosage should
be decreased to 0.5 mg/kg/day and further decreased
to 0.3 mg/kg/day, if necessary |
|
| 2006 |
deflazacort starting at 0.9 mg/kg/day with
1,000 units of vitamin D and 750 mg of calcium
for average of 5.5 years |
ability to climb four stairs, rise from
floor and walk 10 meters (33 feet) preserved
significantly in treated boys compared to
untreated
respiratory function significantly greater
at age 18 in treated compared to untreated
boys; by 18, no treated boy required ventilation,
compared to 46 percent untreated
4 of 40 treated boys had cardiomyopathy,
compared to
20 of 34 untreated
by age 18, 4 of 40 treated boys had significant
spinal curvature, compared to 30 of 34 untreated
|
treated boys were significantly shorter
than untreated
some treated boys gained excessive weight
22 of 40 treated boys developed cataracts,
compared to none of the untreated
long bone fractures same (25 percent) in
treated and untreated groups
vertebral fractures in 3 treated boys and
