Stool examination for occult blood in severe hookworm infection in our study compared with other studies


Govindarajalu Ganesan

Objective: Stool examination for occult blood in patients with severe hookworm infection in our study was compared with other studies. Methods: A study of 1100 patients who had undergone upper gastro-intestinal endoscopy for a period of four and half years from May 2009 to October 2013 was carried out. In all the patients found to have hookworms in duodenum, investigations were done to know about the presence of anaemia. In patients with severe anaemia [haemoglobin <7g/dl or g%] due to severe hookworm infection stool examination was done to look for the presence or absence of occult blood. The results were found as given below. Results: Out of these 1100 patients, 14 patients found to have hookworms in duodenum were taken into consideration for our study. Out of these14 patients, 2 were found to have severe anaemia [haemoglobin <7g/dl or g%] due to severe hookworm infection. But in both these patients, stool examination was negative for occult blood despite a heavy burden of hookworm infection with severe anaemia. Conclusion: Thus even a heavy burden of hookworm infection with severe anaemia can present with negative stool examination for occult blood. Hence upper gastro intestinal endoscopy should be done to confirm the presence of hookworms in all patients with severe anaemia even when stool examination is negative for occult blood.
