Sickle cell anemia:
Sickle cell anemia is caused by an autosomal
recessive inherited disorder which results as
hemolysis. The genetic abnormality is due to
substitution of the amino acid valine for glutamic
acid at the sixth position on the beta globulin
chain and was first described over one hundred
yrs ago [10]. Hemoglobin S, the hemoglobin that is
produced as a result of this defeat, is a
hemoglobin tetramer (alpha 2/ beta S2) that is
poorly
soluble

deoxygenated.
Over all the incidence of sickle
cell disease exceeds that of most other serious
genetic disorder including cystic fibrosis and
hemophilia [12].
Sign and symptoms: Sickle cell anemia has
symptoms likeShortness of breath, Dizziness, Headaches,
Coldness of hand and feet, Paler than normal skin
or mucous membranes (the tissue that lines your
nose, mouth, and other organs and body cavities),
Jaundice (a yellowish color of the skin or whites
of the eyes).
Figure.2 sickle shapedRBCs
Treatment:
Folic acid and penicillin:
Children born with sickle-cell disease will
undergo close observation by the pediatrician and
will require management by a hematologist to
assure they remain healthy. These patients will
take a 1 mg dose of folic acid daily for life. From
birth to five years of age, they will also have to
take penicillin daily due to the immature immune
system that makes them more prone to early
childhood illnesses [14].
Analgesics:
Painful crises are treated symptomatically with
analgesics; pain management requires opioid
administration at regular intervals until the crisis
has settled. For milder crises, subgroups of
patients manage on NSAIDs (such as diclofenac
or naproxen). For more severe crises, most
patients require inpatient management for
intravenous opioids; patient-controlled analgesia
(PCA) devices are commonly used in this setting.
Diphenhydramine is also an effective agent that is
frequently prescribed by doctors in order to help
control any itching associated with the use of
opioids [15].
Blood transfusions: Blood transfusions are often
used in the management of sickle cell disease in
acute cases and to prevent complications by

decreasing the number of red blood cells (RBC)
that can sickle by adding normal red blood cells
[16]
Hemolytic anemia:
Glucose-6-phosphate dehydrogenase (G-6-PD)
deficiency is an X-linked disorder, in this type of
anemia there is rupture blood cells in blood stream
which leads to acute hemolytic anemia.
Although many G-6-PD variants have been
described, susceptibility to some drugs has been
mainly confined to the G-6-PD Mediterranean
variant largely found in Sardinia. Its incidence in
the North is different from that of the South [17]
Many patients who are already anemic, they also
have jaundice. Splenomegaly, reticulocytosis and
increased osmotic fragility of RBCs. [18]
Symptoms: following symptoms are observedFeeling grumpy, Weakness, Headaches, Brittle
nails, Blue color to the whitish of eye, Pale skin
color, Shortness of breath
Important test for hemolytic anemia: [19]
Absolute reticulocyte count- The reticulocyte
count is used to estimate the degree of effective
erythropoiesis, which can be reported as absolute
reticulocyte count or as a reticulocyte percentage.
Coombs testUsed for the autoimmune
hemolytic anemia, and a condition of a low count
RBC immune system lysis or breaking of RBC
membranes causing RBC destruction.
Coombs test, indirect - it's mostly for prenatal
pregnant women, It detects antibodies against
RBCs that are present unbound in the patient's
serum.
Donath-landsteiner
test-The
DonathLandsteiner test is used for detecting harmful
antibodies related to a rare disorder called
paroxysmal cold hemoglobinuria. The antibodies
form and destroy red blood cells when the body is
exposed to cold temperatures [20].
www.ijprsonline.com
Platelet count- This test measures the number of
platelets in blood. It is used to evaluate bleeding
disorders [21] this test may be used when disorders
caused by low blood platelets such as
thrombocytopenia are suspected
Serum LDH- The LDH level is measured in order
to check for tissue damage, especially to the heart,
liver, kidney, skeletal muscle, brain, and lungs —
all of which elevates the normally low LDH level
in the blood.
Hemosiderin in the urine- This test detects
hemosiderin in urine. Hemosiderin is a pigment
formed when hemoglobin breaks down. This test
is used to evaluate and manage disorders
involving the destruction of red blood cells [21]
Febrile of cold agglutinins- Agglutinins are
antibodies that cause the red blood cells to clump
together Cold agglutinins are active at cold
temperatures. Febrile (warm) agglutinins are
active at normal body temperatures. This article
discusses the blood test used to measure the level
of these antibodies in the blood.
Treatment: [22]
Blood transfusion may be needed. Hemolytic
anemia caused by an overactive immune system
drugs that suppress the immune system may be
used. When blood is destroyed at a fast pace the
body may need extra folic acid and iron
supplements to replace what is being lost.
Pernicious anemia:
Pernicious anemia is a type of vitamin B12
deficiency anemia. The body needs vitamin B12
to make red blood cells. You get this vitamin from
eating foods such as meat, poultry, shellfish, eggs,
and dairy products. A special protein, called
intrinsic factor, helps your intestines absorb
vitamin B12. This protein is released by cells in
the stomach. When the stomach does not make
enough intrinsic factor, the intestine cannot
properly absorb vitamin B12 [23]

which is or was prevalent in the regions where the
trait is common. This selective survival advantage
on carriers (known as heterozygous advantage)
may be responsible for perpetuating the mutation
in populations. In that respect, the various
thalassemias resemble another genetic disorder
affecting hemoglobin, sickle-cell disease. [28]
Anemia in pregnancy:
According to WHO, anemia in pregnancy is
defined as hemoglobin level is less than 11 g/dl
and hematocrit level is less than 33% at any stage
of pregnancy [26]. Anemia of pregnancy affects
women of low socioeconomic status. According to
WHO 52% of pregnant women from undeveloped
or developed countries area anemic as compared
with 20% from industrialized nation [24].The risk
of anemia in pregnancy increases with progression
of pregnancy by CDC criteria among low income
pregnant women in the US 8% are anemic in the
first trimester ,12% in the second & 34% in the
third [25] . Hydremia of pregnancy was first
proposed by German & French physician in the
1830s formally demonstrated in 1934 by
Dieckmann & Degner [26].Folate deficiency is
historical regarded as the second most common
cause of anemia of pregnancy after iron deficiency
& B12 dificiency is more prevalent. In studies,
from India, Turkey, Africa, Newfoundland, &
Venezuela 10% to 100% of pregnant women have
a folate deficiency where as 30% to 100% have
vit. B12 deficiency. The prevalence of folate or vit
b12 deficiency increased with gestation [27].
Alpha (α) thalassemias
Thalassemia:
Thalassemia can cause significant complications,
including pneumonia, iron overload, bone
deformities and cardiovascular illness. However
this same inherited disease of red blood cells may
confer a degree of protection against malaria,
The α thalassemias involve the genes HBA1 [29].
And HBA2 [30]. inherited in a Mendelian recessive
fashion. There are two gene locii and so four
alleles.
Beta (β) thalassemias
Beta thalassemias are due to mutations in the
HBB gene on chromosome 11[31] also inherited in
an autosomal-recessive fashion.
Aplastic anemia:
Aplastic anemia is a term which defined as
destruction of bone marrow to produce RBC.
Aplastic anemia is rare disease but approx. 2000
patient diagnosed in America in every year [32].
Two mechanisms have been suggested for bone
marrow failure. The first mechanism is direct
hematopoietic injury by chemicals (e.g. benzene).
The second mechanism, supported by clinical
observations and laboratory studies, is immunemediated suppression of marrow cells [33].

Pathophysiology of aplastic anemia:
Figure 4. Immune destruction of
hematopoiesis [35].
Antigen representing cells (APCs) trigger T-cell
to activate and proliferate. A transcription factor
which binds to the interferon-y promoters’ site
and induce gene expression and reduce gene
transcription [36]. Patient with aplastic anemia
shows constitutive T-bet expression and low SAP
levels, TNF-a and IFN-y up regulate other T-cell
cellular receptor and also the FAS receptor
Increased production of interleukin-2 leads to
polyclonal expansion of T- cell. Activation of fas
ligand leads to apoptosis of target cell which
inhibit the transcription of cellular genes and entry
into the cell cycle [37]. INF-y is a potent inducer of
many cellular genes and NOS (nitric oxide
synthase) and production of toxic gas and NO [38].
The processes ultimately lead to reduced cell
cycling and cell death by apoptosis.

Iron
deficiency
causes
approximately half of all anemia cases worldwide,
and affects women more often than men. World
estimates of iron deficiency occurrence are
somewhat vague, but the true number probably
exceeds one billion people [39]. The most
significant cause of iron-deficiency anemia is
parasitic worms: hookworms, whipworms, and
roundworms. Worms cause intestinal bleeding,
which is not always noticeable in faeces, and is
especially damaging to growing children. [40]
Malaria, hookworms and vitamin A deficiency
contribute to anemia during pregnancy in most
underdeveloped countries [40].
Diagnosis, cause and treatment of anemia [41] :
In the below table different types of anemia,
description, causes, and their diagnosis and
treatments are described.
Iron-deficiency anemia (or iron-deficiency
anaemia) is a common anemia (low red blood cell
or hemoglobin levels) caused by insufficient

Homeopathic treatment for anemia [43]:
Homeopathic treatments are used since ancient
time in India and other countries. It is popular
because of its availability, cheap in cost and
mostly due to fewer side effects. Few drugs and
their contribution is mentioned in the below table
.4
Oral iron supplements:
There are two forms of supplemental iron: ferrous
and ferric. Ferrous iron is better absorbed and is
the preferred form of iron tablets. Ferrous iron is
available in three forms: ferrous fumarate, ferrous
sulfate, and ferrous gluconate. A 325 mg iron
supplement contains the following amounts of
elemental iron depending on the type of ironFerrous fumarate. 108 mg of elemental iron,
Ferrous sulfate 65 mg of elemental iron, Ferrous
gluconate ,35 mg of elemental iron.
Dosage: Depending on the severity of your
anemia, as well as your age and weight, your
doctor will recommend a dosage of 60 - 200 mg
of elemental iron per day. This means taking one
iron pill 2 - 3 time during the day.
Side Effects and Safety: Common side effects of
iron supplements include- Constipation and

diarrhea are very common, Nausea and
vomiting, Black stools are normal when taking
iron tablets.
Supplements:
A healthy diet, rich in iron, must be consumed.
Whole grain cereals, legumes and pulses are
good sources of iron. Anemia that is caused
due to deficiency of vitamins can be avoided
by a proper intake of vitamins in the diet.
Consult a diet chart for better guidance.
Pregnant women can take multivitamin pills
and other nutritional supplements at the advice
of the doctor. Beetroot is also very good
source of iron intake.
