Prevalence of Intestinal Parasites in Alcoholics

Abstract

BACKGROUNDIn developing countries both alcoholism and intestinal parasites are very common. Alcoholism and intestinal parasitic infections go hand in hand, not only due to their unhygienic conditions but also due to damage to immune system. The present study was aimed to find out the prevalence of intestinal parasites amongst alcoholics.METHODS 300 alcoholics and non-alcoholics were tested for intestinal parasites. A single stool specimen was collected for detection of intestinal parasites. A saline and iodine mount was examined microscopically to demonstrate the intestinal parasites. Formol ether concentration technique was performed to increase the yield of the eggs and larvae. Water emergence technique and Agar plate culture was performed for Strongyloides stercoralis. Modified Acid Fast staining was done for opportunistic parasitic infections. The categorical outcomes were assessed by Chi Square test. RESULTSThe prevalence of intestinal parasites was more in alcoholics (7.66%) as compared to non-alcoholics (3%). In alcoholics, among the helminths, Strongyloides stercoralis (2.6%) was predominantly seen followed by Ascaris lumbricoides (0.33%) and hookworm (0.33%). Amongst the protozoan parasites, the predominant parasite was Entamoeba histolytica (2.3%) followed by Blastocystis hominis (1.33%) and Giardia lamblia (0.6%). Prevalence of Strongyloides stercoralis had a significant correlation with history of walking barefoot. Eosinophilia was predominantly seen in alcoholics with intestinal parasites. CONCLUSIONSAlcoholics whether symptomatic or asymptomatic should be screened for intestinal parasites especially Strongyloides stercoralis to prevent morbidity. Presence of eosinophilia is a good positive predictive marker for intestinal parasitic infection. All alcoholics should be counselled regarding personal hygiene specially about barefoot walking to prevent infection with Strongyloides stercoralis.
