responsible for more than 1.5 million deaths every year, hence is a major global health problem specially in developing countries. Interrelation

between Tuberculosis and malnutrition is as old as the disease itself. Disease outcome and morlality in PTB depends on strength of immune system

which in turn inuenced by the nutrilional status of an individual. Calcium is an essential macro mineral is altered in various infection including

granulomatous diseases.

MATERIAL AND METHOD : The study was conducted on 100 adults (both males and females) from low socioeconomic status out of which 40

were newly diagnosed (Group A), 30 were relapsed PTB cases (Group B) and 30 were healthy age and gender matched non family member of

patients that served as controls (Group C). After an informed consent, all were subjected to anthropometric measurements and biochemical

investigations i.e Total protein (Biuret Method, Accurex), Albumin (BCG dye binding method Accurex). Total Calcium (Arsenozo III Methord,

Accurex), Phosphorus (Phosphomolybdate UV Method, Accurex) and ALP (Kinetic Method).

RESULT AND DISCUSSION : No signicant difference was seen in ages among all the groups. BMI, Total protein and Albumin were

signicantly (P<0.05) low in Pulmonary Tuberculosis (PTB) than controls. Since TB is associated with severe chachexi, wasting and low albumin,

lonic and corrected TCa was calculated and were singnicantly high (p<0.05).

CONCLUSION : Poor nutrition(Low protein)may be a risk factor for the tuberculosis. And studies indicating that incidence of tuberculosis is

unusually high among malnourished people. The host protective immune mechanism of TB infection depends critically on the interaction and

cooperation between monocyte –macrophages and t–lymphocytes .
