ABSTRACT:
Sickle cell Anemia is a serious Condition in
which the Red Blood cell can become sickles shaped {Shaped like a “C”}. They
don’t move easily through blood vessels. They are stiff and sticky and tend to
form clumps and get stuck in blood vessels. The clumps of sickle cells block
blood flow in the blood vessels that leads to the limbs and organs. Blocked
blood vessels can cause pain, serious infections and organ damage.1
There is no specific therapy.2
In sickle cell anemia we treat only
symptoms. In present paper Author is introducing Homoeopathic Medicinal System
to treat Sickle cell Anemia.
KEY-WORDS:.
INTRODUCTION:
Sickling Phenomenon was first described by
Herrick in 1910. And Pauling showed that the abnormality resided with
hemoglobin in 1949.2
Hemoglobin is the red coloring matter of
blood, which is present in red blood cells.
It is a conjugated protein consisting of
heme and the protein globin. It has molecular weight of 64,450. It can combine
with oxygen and acts as the transport mechanism for oxygen with in blood. It
contain 4 gm atom of iron per mole in the ferrous (Fe++) state.6
Let us see the structure of heme. It is a
chromo protein consist of two part 96% is a specific simple protein known as
globin (histone) and other 4% is a non specific prosthetic group an iron.
Containing pigment called heam.8
Heam is a metalloporphyrin where the metal
is iron. The iron content of hemoglobin is about 0.34% and about 3gm of iron is
present as hemoglobin in the total amount of blood of an adult. Iron remains in
ferrous (Fe++) form.
Globin helps heam to keep the iron ferrous
state and to combine loosely and reversibly with molecular oxygen.8

Sickle cell anemia (Hbs) is the
most common form of abnormal hemoglobins. It is so named because the
erythrocytes of this patients adopt a sickle shaped (Crescent like).3

with 2a (alpha) and 2B (beta) shade – heme3
Synonyms
of sickle cell anemia are –
. Hemoglobin SS Diseases
. Hbs.
. Sickling disorder due to Hemoglobin S.
. Hemoglobin S diseases.
. Sickle cell disorders
. SCD.
The structure of hemoglobin (as described
all ready) contains two alpha and two beta globins chain. In case of sickle of
anemia the hemoglobin (Hbs) has two normal alpha globins and two abnormal
(mutant) beta globins chain. This is due to difference in a single amino acid.
In Hbs, glutamate at sixth position of beta chain is replaced by valine.
(Glu B6 ŕ Val).
Fig -3 - Sickle cell anemia is due to a change
(missense - mutation) in the single nucleotide (thymine - adenine) of beta
globin gene.
This error causes the formation of altered
codon (GUG in place of GAG) which leads to incorporation of valine instead of
glutamate at the sixth position in beta chain.3
Sickle cell anemia affects millions of
people worldwide. It’s most common people whose families come from Africa,
South or Central America (Specially panama) Caribbean islands, Mediterranean
countries (Such as Turkey, Greece and Italy) INDIA and Saudi Arabia. In united
State Sickle cell anemia affects about 70000 peoples. It mainly affects
African, American with the condition occurring in about in every 500 African
American births. Hispanic American are also affected, the condition occurs in 1
out of every 1000 to 1400 Hispanic American births. About 2 millions American
have sickle cell trait. About in 12 African, American has sickle cell trait.
Signs
and symptoms of Sickle cell Anemia – the signs and symptoms of sickle cell anemia are
different in each person. Some people have mild symptoms others have very
severe symptoms and are often hospitalized for treatment. Although sickle cell
anemia is present at birth many infants don’t show any sign until after 4
months of age.
The most sign and symptoms are linked to
anemia and pain. Sudden episodes of pain throughout the body are common
symptoms of sickle cell anemia and are often referred to as sickle cell crises.
Occurs when the Red blood cells sickle and stick together in clumps. The clumps
blocked the flow of blood through the small blood vessels in limbs and organs.
Sickle crises can cause acute and chronic pain the pain usually (in acute) from
hours to a few days’ chronic pains for weeks to months. Many factors can
contribute to a sickle cell crises often more than one factor is involved and
the exact cause can’t be identified. The most common site affected by sickle
cell crises are bones, lungs, abdomen and joints. The blocked blood flow can
cause pain and organ damage.
When sickle cell blocked the small blood
vessels in hand or feet pain and swelling along with fever can occur swelling
usually occurs on the back of the hand and feet and moves in to fingers and
toes this may be first sign of sickle cell anemia in infants.
Splenic (Sequestration) Crisis - The spleen
is an organ in the abdomen that filters out abnormal red blood cells and helps
fight infection. Sometimes, the spleen traps many cells that should be in the
bloodstream and it grows large. This causes anemia. Blood transfusions may be
needed until the body can make more cells and recover. If the spleen becomes
too clogged with sickle cells, it can’t work normally. It begins to shrink and
stop working.
Infections - Both children and adults with sickle cell anemia have
a hard time fighting infections. Sickle cell anemia can damage the spleen. Infants and young children with a damaged spleen are more
likely to get infections that can kill them within hours or days. Pneumonia is
the most common cause of death in young children who have sickle cell anemia.
Meningitis, influenza, and hepatitis are other infections that are common in
people with sickle cell anemia.
Acute
Chest Syndrome - Acute
chest syndrome is a life-threatening condition linked to sickle cell anemia.
It's similar to pneumonia and is caused by an infection or by sickle cells
trapped in the lungs. People with this condition usually have chest pain,
fever, and an abnormal chest x ray. Over time, lung damage may lead to pulmonary
arterial hypertension
Delayed
Growth and Puberty in Children - Children with sickle cell anemia often grow more slowly and reach
puberty later than other children. A shortage of red blood cells (anemia)
causes the slow growth rate. Adults with sickle cell anemia often are slender
or small in size.
Stroke
- Sickle-shaped red blood
cells may stick to the walls of the tiny blood vessels in the brain. This can
cause a stroke. This type of stroke occurs mainly in children. The stroke can
cause learning disabilities or more severe problems.
Eye
Problems -The retina, a
thin layer of tissue at the back of the eye, takes the images you see and sends
them to your brain. When the retina doesn’t get enough blood, it can weaken. A
weak retina can cause serious problems, including blindness.
Priapism - Males with sickle cell anemia may have painful and unwanted erections
called Priapism (PRI-a-pizm). This happens because the sickle cells stop blood
flow out of an erect penis. Over time, Priapism can damage the penis and lead
to impotence.
Gallstones
- When
red blood cells die, they release their hemoglobin, which the body breaks down
into a compound called bilirubin. When there is too much bilirubin in the body,
stones can form in the gallbladder. Gallstones can cause steady pain that lasts
for 30 minutes or more in the upper right side of the belly, under the right
shoulder, or between the shoulder blades. The pain may happen after eating
fatty meals. People with gallstones may have nausea, vomiting, fever, sweating,
chills, clay-colored stool, or jaundice (yellowish color of the skin or whites
of the eyes).
Ulcers
on the Legs - Sickle cell
ulcers (sores) usually begin as small, raised, crusted sores on the lower third
of the leg. Leg sores occur more often in males than in females and usually
appear between the ages of 10 and 50. The cause of leg ulcers is not clear. The
number of ulcers can vary from one to many. Some heal rapidly, but others
persist for years or come back after healing.
Pulmonary
Arterial Hypertension (High Blood Pressure)
- Damage to the
small blood vessels in the lungs makes it hard for the heart to pump blood
through the lungs. This causes blood pressure in the lungs to increase. This
condition is called pulmonary arterial hypertension. Excessive shortness of
breath is an important symptom linked to this problem.
Multiple
Organ Failure - Multiple
organ failure is rare, but serious. It happens when a person has a sickle cell
crisis that causes two out of three major organs (lungs, liver, or kidney) to
fail. Symptoms linked to this complication are a fever and changes in mental
status such as sudden tiredness and loss of interest in your surroundings 1
Premature
death – Homozygous
individual of sickle cell anemia die before they rich adulthood (< 20years).3
Infection
– Salmonella infection is
found more in this disease.6
Let us see the block blood vessels due to
Sickle shaped Red Blood Cells.

and Sickle Cell RBCs
Figure A shows normal red blood cells flowing freely in a blood vessel.
The inset image shows a cross-section of a normal red blood cell with normal
hemoglobin.
Figure B shows abnormal, sickled red blood cells clumping and blocking the
blood flow in a blood vessel. The inset image shows a cross-section of a
sickled red blood cell with abnormal strands of hemoglobin1
Diagnosis
of Scikle cell anemia -
Early diagnosis of sickle cell anemia is very important
So that children who have the condition can
get proper treatment. In the United States, 44
States, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands now
test all newborns for sickle cell anemia. In the other six States, you can
request a sickle cell test. The test uses blood from the same blood samples
used for other routine newborn screening tests. It can show whether the newborn
infant has sickle cell anemia or sickle cell trait. If the first test shows
some sickle hemoglobin, a second blood test is done to confirm the diagnosis.
The second blood test looks at how hemoglobin moves in an electric field, a
process called electrophoresis (ee-LEK-tro-for-EE-sis). Sickle hemoglobin moves
differently than normal hemoglobin. Electrophoresis is usually used to diagnose
older children and adults. It’s also possible to identify sickle cell anemia
before birth. This is done using a sample of amniotic fluid or tissue taken
from the placenta. (Amniotic fluid is the fluid in the sac surrounding a
growing embryo. The placenta is the organ that attaches the umbilical cord to
the mother’s womb.) This test can be done as early as the first few months of
pregnancy. It identifies the sickle gene, rather than the hemoglobin it makes.1
1. Sickle test – this is a simple microscopic examination of blood smear prepared
by adding reducing agents such as sodium dithionite sickle erythrocytes can be
detected under the microscope.
2. Electrophoresis – When subjected to electrophoresis in alkaline medium (pH –
8.6) sickle cell hemoglobin moves slowly towards anode than does adult
hemoglobin. The slow mobility of Hbs is due to less negative charge, caused by
the absence of glutamate residues that carry negative charge. In case of sickle
cell trait, the fast moving HbA and slow moving Hbs are observed. The
electrophoresis of hemoglobin obtained from lysed erythrocytes can be routinely
used for the diagnosis of sickle cell anemia and sickle cell trait.
Fig – 5 - Electrophoresis of hemoglobin’s at pH 8.6
HbA –
Normal adult Hemoglobin; HbS – Sickle cell Hemoglobin.3
Treatment – There is no specific therapy avoid fatigue, exposure to cold,
stress infection, fever, dehydration. Folic acid is recommended to counteract
the secondary folate deficiency that develops due to rapid red cells turn over.
Various methods have been suggested form time to time for the painful crises.
Crises are due sludging and vascular occlusion with or without myleo
suppressive effects.
It is most unusual for the new
born to get crises. This is explained on the basis of high fetal hemoglobin
level and low level of HbS. Carbonic anhydrous inhibitors, alkalization with sodium
bicarbonate administration conversion of a portion of Hb to oxy Hb. By oxygen
administration or by carbon monoxide to carboxy hemoglobin or mat hemoglobin.
Has been no benefit. Though this form do not Sickle. Magnesium salts
therapeutic defibrination, anti coagulant, expansions of blood volume with low
molecular weight. Dextrans have been suggested but are still under
investigation. The best is to provide supportive and symptomatic therapy.
Splenectomy is of moderate benefit in those subjects where there is a excessive
blood destruction. Red Cell survival increases after Splenectomy and the
frequency of blood transfusion is decreased. Heme turnover is increased during
urea therapy due to increased hemolysis of red cell. Which are prevented from
aggregating in the microcirculation.
Recent suggestion is
administration of oral or intravenous injections of 10 % sodium citrate, 6G in
400ml. Of water every two hours for 2 days. For 24 hour followed by the same
every 2 hours for 2 days and then every 6 hours. Codeine is helpful. Sodium
citrate may be given in I.V. 200ml. Of M/6 sodium lactate in 3 hours. Hyper
transfusion is also used. Corticosteroids have been beneficial, phenothiazine
and oral contraceptive are of no value. Analgesic and antipyretic drugs must be
used for comfort of the patient. Intravenous distilled water may interfere with
sickling. Antibiotics should be used if infection is present. Blood transfusion
is necessary for aplastic crises and in pregnancy. Packed Red Cells are
preferable. Transfusion decreases viscosity and is helpful. Repeated
transfusion would lead to hemosiderosis and iron over load. According to
modified muryamma hypothesis for the molecular mechanism of sickling. Which
implicates intertertrameric hydrophobic bond on the basis of this hypothesis
intravenous urea in sugar solution is used as an effective chemical agent for
desickling. This solution reverses and blocks sickling without hemolysis. A
high blood nitrogen gradient of 150 to 200mg. Per 100ml./ is achieved rapidly and
maintained until the vascular occlusion is reversed. The relief of pain signals
this and the urea is discontinued. The maintenance of hydration is critically
important and is achieved by the adertically importance and is achieved by the
administration of ringers lactate solution by a central; venous catheter to
prevent the complication occasionally caused by 30% urea solution prepared by
taking 0.05 to .10M. urea (300 to 600mg./100ml.) in sugar solution in a
peripheral vein.
Side effects – sedation that is desirable and diuresis. Oral prophylactic urea
reduces the number of crises. 160gm of urea per day divided into four doses are
given individualization is necessary. Bon should be maintaining at 40 to
50mg/100ml.
Since cyanate (NCO) is present
in urea, it can react with N-terminal residues of protein to form carbimilate
derivative. This reaction is essentially irreversible.
Low concentration of cyclamate
inhibit Sickling the amount bound cyanate per moil is in range of 0.1 to 1per
mole of hemoglobin this not only prevents sickling but also blocks the gelling
of hemoglobin no side effect were observed.
Partial exchange perfusion is
used for prophylaxis and treatment two units of buffu coat free packed sales in
two units of whole blood every 6 to 8 weeks for 1.5 to 6 years. This
maintenance from 15 to 40% normal circulating RBCs. There is a melioration of
crises in 24 hours. And complete relief in 48 hours.
Frequency of crises is not
affected the hospital stay is reduce.

New
Treatments - Today,
research on sickle cell anemia is looking at bone marrow transplants, gene
therapy, and new medicines. The hope is that these studies will provide better
treatments for sickle cell anemia. Researchers also are looking for a way to
predict the severity of the condition.
Bone
Marrow Transplant - Bone
marrow transplant can be a very effective treatment for sickle cell anemia, but
because of its risks, only some patients can or should have this procedure. The bone marrow transplant procedure is risky and could
result in serious side effects and even death. It’s usually used only for
younger patients with severe sickle cell anemia, but the decision is made on a
case-by-case basis. Bone marrow used for a transplant must come from a closely
matched donor, usually a close family member, who doesn’t have sickle cell
anemia.
Gene
Therapy - Gene therapy is
being studied as a possible treatment for sickle cell anemia. Researchers are
looking to see whether a normal gene can be planted in the bone marrow of a
person with sickle cell anemia, and thus cause the body to produce normal red
blood cells. Researchers also are studying the possibility of treatment to
“Turn off” the sickle cell gene or “turn on”
a gene that makes red blood cells behave normally.
New
Medicines -New medicines
being studied are:
·
Butyric acid. This is a food additive that may increase normal
hemoglobin in the blood.
·
Clotrimazole. This is used now to treat fungus infections. This
medicine helps prevent the loss of water from a red blood cell and can keep the
cell from turning into a sickle cell.
·
Nitric oxide. This may make sickle cells less sticky and keep
blood vessels open. People with sickle cell anemia have low levels of nitric
acid in their blood. 1
Now the question is arises how
can sickle cell anemia is prevented?
As we know sickle cell anemia is
an inherited condition. Children who inherit the genes for sickle cell anemia
can’t prevent developing the condition, although they can take steps to reduce
complications. People who are in groups that are at high risk for sickle cell
anemia and who are planning to have children may want to consider genetic
counseling beforehand. A counselor can help you understand your risk of having
a child with the condition and help explain the choices that are open to you.
You can get information about genetic counseling from health departments,
neighborhood health centers, medical centers, and clinics that care for people
with sickle cell anemia.
A procedure called
pre-implantation genetic diagnosis can improve the chance that two people with
sickle cell trait will have a child with normal hemoglobin. Eggs from the
mother and sperm from the father are mixed together in a laboratory dish. The
eggs that become fertilized are checked for sickle cell anemia. Fertilized eggs
that don’t have sickle cell genes are then implanted in the mother’s womb. This
is a complex procedure done only in a few places, and it doesn’t always work. 1
Relation with other diseases: –
01. Person suffering from sickle
cell anemia show an increased resistance to malaria.6
Because the life span of the
sickle cell is less than the time needed for the malaria parasite to mature inside
the cells.7
In sickle cell anemia, a
lower-than-normal number of red blood cells occurs because sickle cells don’t
last very long. Sickle cells die faster than normal red blood cells, usually
after only about 10 to 20 days. The bone marrow can’t make new red blood cells
fast enough to replace the dying ones. The result is anemia.1
The above all information are of
sickle cell anemia and its treatment was also as in allopathic medicinal system
but Homeopathy Medicinal system claim that according to there treating manner
if we remove the symptoms we remove the disease Hahnemann steps into say for
the first time in all history remove the effects and you remove the disease the
cause of effect “ Cessat effectus Cessat causa.”5
Now as in the care effected by
the removal of the whole of the perceptible signs and symptoms of the disease.
The internal alternation of the vital force to which the disease is due
consequently the whole of the disease is at the same time removed. It follows
that the physician has only to remove the whole of the symptoms in order at
same to abrogate and annihilate the internal change that is to say he morbid
derangement of the vital force consequently the totality of the disease the
disease itself.4
As same line we can see
according to allopathic medicinal system for treatment of sickle cell anemia –
“the best is to provide supportive and symptomatic therapy.”2
In allopathic medicinal system
generally physician provide folic acid to sickle cell anemic patient -
Folic acid is recommended to
that develops due to rapid cell turn over.2 Many patients are prescribed a vitamin called
folic acid (folate) to help prevent some of the complications of sickle cell
anemia.1
In homoeopathic medicinal system the drugs which are provided to
patient in anemic condition are –
. Picricum Acidum.
. Calcarea Phosphorica.
. Ferrum Iodatum.
. Ferrum Mettallicum.
. Ferrum Phosphoricum.
. Vanadium. Etc.9
These drugs are prescribe only
on the bases of symptoms. It is not to each patient gives same drug. If the
symptoms are different the drug will also different.
Dr.K.D.Sharma. in INDIAN HOMEO
REMEDIES manufacture SECALGO. This is available in market. This drug is use in
anemia, weakness and in sickling. If any patient who belongs the symptoms to be
subject to take doses of secalgo.
Secalgo basically consist of two
components – Ferrum mettalicum. And Vanadium.
Ferrum Metallicum – Best adapted to young weakly persons, anemic and chlorotic,
with pseudo plethora, who flush easily.9
Vanadium – Which increases amount of hemoglobin.9
These both are metals.
According to homoeopathic
medicinal system = by use of such medicines as are capable of producing in the
healthy individual an opposite state to that of the case o be cured.4
Means those crude drugs produce
the effects in healthy voluntary that are use to treat that particular disease
in it dilution form.
E.g. Hahnemann, took four
drachms of china (cinchona officinalis, Peruvian bark)9 twice a day. He had paroxysms of chill and
fever. In his practice as a physician he had seen similar paroxysms of chill
and fever. He had cured them with china.5
Conclusion and Result :–
Sickle cell anemia is serious
condition and not have any permanently treatment Effective treatments are
available to help relieve the symptoms and complications of sickle cell anemia,
but in most cases there’s no cure1 but according to reference.
Remove the effects and you remove the disease.5 the homoeopathy
medicinal system is also a subject to treat patient those are suffering from
sickle cell anemia.
