• Hemoglobinopathies and thalassemia are the commonest
genetic disorders in the world. In India also they constitute
major public health problem. [1] .
• The Government is aware of this problem so sickle cell
prevention and control program has implemented in 19 high
prevalent districts in Maharashtra since 2008.[2,3]
• To arrive at the exact diagnosis of these abnormal
haemoglobins , a battery of screening tests should be
performed since, presumptive identification usually requires
minimum two techniques ,based on different principles.[4]
BACKGROUND

• We screened samples by solubility test, NESTROFT test and
electrophoresis. The positive samples were further evaluated
by HPLC and also confirmed by family studies..
• The present study aims at evaluating haemoglobin
disorders in Nanded region of Maharashtra during the
period of September 2011 to May 2014.

MATERIALS AND METHODS:
• We conducted prospective and retrospective study from
September 2011 to May 2014. We set inclusion and exclusion
criterias.
• Inclusion criteria:
• 1)Samples showing Hb < 10 gm % ,MCV < 78fl
• 2)Sample of patients having clinical and laboratory suspicion
of hemolytic anaemia
• 3)Samples which showed positive picture of
haemoglobinopathies on Hb electrophoresis at Rural Health
Centre
• Exclusion criteria:
• Patients who received blood transfusion in the last 6 months
were excluded from the study.

Discussion
Table 6:Prevalence of Sickle Disease
Study Prevalence
Kate et al (2000) 0.5%
Vasaikar et al(2009) 1.09%
Present study 0.81%

• Frequency of β-thalassemia in India ranges from 3.5-15 % in
general population[3]
• Roshan Colah et al found prevalence of thalassemia trait 2%
in our region
• We found its prevalence as 2.17%
• This study is pilot study contributing data of prevalence of
Thalassemia major ,Sickle trait and Double heterozygous in
Nanded region of Maharashtra.
• Caste wise distribution of our study matches with study
conducted by M.A. Sameer et al in same region in 2014[7].

Conclusion
• Early detection of haemoglobin disorder is of paramount
importance in treatment, management and prevention of
genetic transmission. Also carrier identification of these
diseases would be useful to create awareness regarding partner
selection, prenatal diagnosis thereby reducing future disease
burden in the society
• The present study is useful to generate detailed data of
haemoglobin disorders so that health care resources can be
successfully targeted at them.
