“A COMPARATIVE STUDY OF ANAEMIA WITH THE
DEGREE OF GLYCAEMIC CONTROL IN TYPE 2
DIABETES MELLITUS ”
6. BRIEF RESUME OF INTENDED WORK:
6.1 NEED FOR THE STUDY: There are currently approximately 40.9 million patients
with diabetes mellitus in India and this number is expected to rise to about 69.9 million
by the year 2025. This high burden of diabetes is likely to be associated with an increase
in associated complications.1
Type 2 Diabetes Mellitus is a non-autoimmune, complex, heterogeneous and polygenic
metabolic disease condition in which the body fails to produce enough insulin,
characterized by abnormal glucose homeostasis. Its pathogenesis appears to involve
complex interactions between genetic and environmental factors. Type 2 Diabetes
Mellitus occurs when impaired insulin effectiveness (insulin resistance) is accompanied
by the failure to produce sufficient cell insulin.
In type 2 diabetes mellitus patients glycosylated haemoglobin (HbA1c) is an effective
tool in monitoring long term blood glucose control.HbA1c gives an accurate estimate of
the average of the plasma glucose levels from the past 8 to 12 weeks. Hence glycosylated
haemoglobin becomes an important marker of glycemic control in diabetes mellitus.
HbA1c testing is a measure of diabetic glycaemic control. Diabetes control is categorized
as poor control (HbA1c levels > 9%), moderate control (HbA1c levels between 7% and
9%) and good or desired control (HbA1c levels <7%).2
Anaemia is one of the world’s most common preventable condition yet it is often
overlooked especially in people with Diabetes Mellitus.3
Anaemia is a common finding in patients with diabetes. Diabetes related chronic
hyperglycaemia can lead to a hypoxic environment in the renal interstitium which results
in impaired production of erythropoietin by the peritubular fibroblasts and subsequently
anaemia occurs.3
Anaemia in patients with diabetes mellitus might contribute to pathogenesis and
progression of cardiovascular disease and aggravate diabetic nephropathy and
retinopathy. However, an emphasis on regular screening for anaemia, alongside that for
other diabetes – related complications, might help to delay the progression of vascular
complication in these patients.3
6.2 REVIEW OF LITERATURE :
Anaemia may be more common in diabetes and develop earlier than in patients with
renal impairment from other causes. However, patients with diabetes may be more
vulnerable to the effects of anaemia because many also have significant cardiovascular
disease and hypoxia – induced organ damage.4
Although anaemia can be considered a marker of kidney damage, reduced hemoglobin
levels independently identify diabetic patients with an increased risk of microvascular
complications, cardiovascular disease and mortality.5
Many factors have been suggested as the reason for the earlier onset of anaemia in
patients with diabetes, including severe symptomatic autonomic neuropathy, causing
efferent sympathetic denervation of the kidney and loss of appropriate erythropoietin
production; damage to the renal interstitium; systemic inflammation; and inhibition of
erythropoietin release.6
In spite of the plethora of reports on the presence of anaemia in diabetic patients with
renal insufficiency, limited study exists on the incidence of anaemia in diabetics prior to
the evidence of renal impairment. This may explain why most diabetic patients with
normal renal function are rarely tested for anaemia. The need for more studies on
incidence of anaemia in diabetic patients prior to renal impairment has therefore become
imperative, in order to increase the level of awareness and understanding of anaemia
amongst diabetic patients.7
Correction of the anaemia not only lessens fatigue, greater exercise tolerance, and an
improved quality of life but also to a reduction in outpatient and hospital admissions for
congestive heart failure. Data are accumulating that suggestive treatment of anaemia will
slow the progression of microvascular and macrovasular complications including postural
hypotension from autonomic neuropathy, retinopathy and diabetic nephropathy. Promptly
diagnosing and treating anaemia in patients with diabetes may result in improved quality
of life and decreased morbidity and mortality.8
6.3 OBJECTIVES OF THE STUDY:
1. To compare the hemoglobin levels among normal controls and patients of type 2
diabetes with HbA1c levels :
i)
ii)
Below 7 %
Above 7 %
2. To identify the undetected cases of anaemia in type 2 diabetes.
7. MATERIALS AND METHODS:
7.1a SOURCE OF DATA
35 patients of type 2 diabetes mellitus with their glycosylated hemoglobin levels less than
7 %,
35 patients of type 2 diabetes mellitus with their glycosylated hemoglobin levels more
than 7 % attending the Medicine outpatient department of Rajarajeswari Medical College
and Hospital will be the subjects for the study.
35 age and sex matched controls will be selected randomly from in and around
Rajarajeswari Medical College and Hospital.
Informed written consent will be taken from all the subjects. The study will be conducted
from January 2013 to January 2014.
7.2a INCLUSION CRITERIA:

Males and Females aged 35 to 65 years.

7.2 METHOD OF COLLECTION OF DATA
All the subjects and control will be generally and systemically examined to rule
out the presence of other co – morbid conditions.
Anthropometry: Height, Weight, BMI will be measured, waist to hip ratio will be
collected.
A questionnaire will be provided to the controls and subjects to know about their
lifestyle, past history, family history and list of medications.
(ANNEXURE 1 attached)
Blood sample from the study and control group will be drawn under complete
aseptic precautions, (ANNEXURE 2 attached) after obtaining informed consent.
(ANNEXURE 3 attached)
Fasting and two hours post prandial blood sample will be collected for analysis in
vacuum evacuated tubes as follows:

Haemogram, Peripheral Blood Smear, Renal Function Test and Iron Profile.
2. Fluorides EDTA vacuum evacuated tubes for estimation of blood glucose and
glycosylated hemoglobin.
3. Sterile Urine container for the analysis of Urine Glucose and Urine
Microscopy.
4. Sterile stool container for the analysis of Stool Microscopy.
7.2 PLAN FOR DATA ANALYSIS
The results will be analysed using the SPSS software 16th version.
ANOVA and paired “ t” tests will be used for statistical analysis of the data. All the
results will be expressed as Mean ± SD.

The following biochemical and hematological parameters will be assessed using
the following methods:
1. Complete Blood Count by Standard Method.
2. Peripheral Blood Smear by Microscopy.
3. Iron Profile by Ferrozine Iron Method without deproteinization.
4. TIBC by Spectrophotometric Assay
5. Serum Folic Acid levels by Chemiluminescence Automated Assay
