Background:
We assessed whether oxidant-stress and inflammation in â-thalassemia
could be controlled by the novel oral iron chelator deferasirox as
effectively as by deferoxamine.
Design and Methods:
Forty-nine subjects were enrolled from seven sites and studied at
baseline, and after 1, 6, and 12 months of therapy. Malondialdehyde,
protein carbonyls, vitamins E and C, total non-transferrin bound iron,
transferrin saturation, C-reactive protein, cytokines, serum ferritin
concentration and liver iron concentration were measured.
Results:
Liver iron concentration and ferritin declined significantly in both
treatment groups during the study.
This paralleled a significant decline in the oxidative-stress marker
malondialdehyde (deferasirox -22%/year, deferoxamine -28%/year,
average decline p=0.006).
The rates of decline did not differ between treatment groups.
Malondialdehyde was higher in both treatment groups than in a group of
30 non-thalassemic controls (p<0.001).
The inflammatory marker high-sensitivity C-reactive protein decreased
significantly only in the group receiving deferasirox (deferasirox -
51%/year, deferoxamine +8.5%/year, p=0.02).
This result was confounded by a chance difference in the level of high-
sensitivity C-reactive protein between the two groups at baseline, but
analyses controlling for this difference suggested an equally large
treatment effect.
Conclusions:
Iron chelation therapy with deferoxamine or with deferasirox was
equally effective in decreasing iron burden and malondialdehyde. The
possible differential effect of the two chelators on inflammation
warrants further investigation.
Key words: iron overload, thalassemia, oxidative stress, inflammation,
hsCRP, C-reactive protein, malondialdehyde, lipid peroxidation,

Nonsense, these are genetic conditions, there is no "cure". The
sideeffects of the full version can be reduced to some extent. It would
be like "curing blue eyes.
What disease are these mutations an adaptation for, what effect do they
have for the course of the disease, and how does it explain the
geographical distribution of them?

Jesus ate specific molecules, and nobody has ever eaten the exact same
ones (in the exact same amounts).
Inflammation is not caused by iron. Iron can contribute to an
existing inflammatory condition, however. A stressor leads to the
cell releasing certain molecules. When a cell contains arachidonic
acid instead of the natural Mead acid, "chronic inflammation" is
possible, even with a minor, persistent stressor. It also seems that
a vicious cycle gets started in some cases, with molecules from the
diet acting as constant fuel for this kind of inflammation (evidence
of macrophage involvement here is clear, as I point out on my site).
"Genetic disease" can be enhanced greatly or brought on by diet,
especially, it seems, those that start during adolescence. Due to the
excessive "growth," which many view as "good," certain genetic
"diseases" that would have never occurred (or would have occurred
during old age, which many people never reached, of course, in "the
good old days") do occur because certain checkpoints are overrun by
the excess stress (growth requires stress). |

"Some children may discontinue chronic transfusions"
Blood, Vol. 94 No. 9 (November 1), 1999: pp. 3022-3026
Hydroxyurea as an Alternative to Blood Transfusions for the Prevention
of Recurrent Stroke in Children With Sickle Cell Disease
Russell E. Ware, Sherri A. Zimmerman, and William H. Schultz
From the Duke Pediatric Sickle Cell Program and the Division of
Hematology-Oncology, Department of Pediatrics, Duke University Medical
Center, Durham, NC.
Children with sickle cell disease (SCD) and stroke receive chronic
transfusions to prevent stroke recurrence.
Transfusion risks including infection, erythrocyte allosensitization,
and iron overload suggest a need for alternative therapies.
We previously used hydroxyurea (HU) and phlebotomy in two young adults
with SCD and stroke as an alternative to transfusions.
We have now prospectively discontinued transfusions in 16 pediatric
patients with SCD and stroke.
Reasons to discontinue transfusions included erythrocyte
alloantibodies or autoantibodies, recurrent stroke on transfusions,
iron overload, noncompliance, and deferoxamine allergy.
HU was started at 15 mg/kg/d and escalated to 30 mg/kg/d based on
hematologic toxicity. Patients with iron overload underwent
phlebotomy.
The children have been off transfusions 22 months, (range, 3 to 52
months).
Their average HU dose is 24.9 ± 4.2 mg/kg/d, hemoglobin concentration
is 9.4 ± 1.3 g/dL, and mean corpuscular volume (MCV) is 112 ± 9 fL.
Maximum percentage fetal hemoglobin (%HbF) is 20.6% ± 8.0% and
percentage HbF-containing erythrocytes (%F cells) is 79.3% ± 14.7%.
Fourteen patients underwent phlebotomy with an average of 8,993 mL
(267 mL/kg) removed. Serum ferritin has decreased from 2,630 to 424 ng/
mL, and 4 children have normal ferritin values.
Three patients (19%) had neurological events considered recurrent
stroke, each 3 to 4 months after discontinuing transfusions, but
before maximal HU effects.
These preliminary data suggest some children with SCD and stroke may
discontinue chronic transfusions and use HU therapy to prevent stroke
recurrence. Phlebotomy is well-tolerated and significantly reduces
iron overload.
Modifications in HU therapy to raise HbF more rapidly might increase
protection against stroke recurrence.

More nonsense, sickle cell anemia is a genetic disorder related to
adaptation to a specific disease. There is no cure any more then there is
for blue eyes. The article claimed no cure only fewer transfusions, not
even close.
The questions remain unanswered from the equally silly first post:
What is that disease, what effect does the adaptation have in its full
version, and how is the geographical distribution explain?
Here is another one, why were they doing transfusions and why did they
want to reduce red blood count?
Warning, gross ignorance alert for upcoming response.

We await the answers for the below, anyone really in the know about these
genetic disorders could answer them in a snap. Search enjine jockies who
don't understand the abstracts they post can not answer them.

Actually, Tom's response to this one was unusually intelligent.
Instead of purporting a cure with a lessening of symptoms, or
otherwise demonstrating his ignorance of the very literature he
claims to review, he abstained from responding. Maybe he is
capable of learning after all.
