Dear Editor,

Liver fluke infestation or Opisthorchiasis is a very important fluke infestation in Indochina.[1] This infection can result in long term complication, which is a well-known malignancy, Cholangiorcarcinoma.[1] The important but forgotten issue on this infection is the nutritional status of the infested cases. Apparently, there is no clear evidence that liver fluke infestation can result in over or under nutrition. According to a recent study in endemic village in Thailand, there are normal, under-and over-nutrition cases with Opisthorchiasis.[2] The picture is very different from the past report when Thailand was less developed.[3] At that time there had been no over nutrition in the endemic village.[3]

The existence of the over nutrition problem among the cases with Opisthorchiasis is a very interesting phenomenon. Some new research group proposes that there can be the hidden pathophysiological process leading to over nutrition in Opisthorchiasis.[4] However, if we consider to the past report,[3] it is unlikely that the over nutrition is caused by parasitic infestation. The problem is the changing life style and increased rate of metabolic syndrome in the endemic villages in Indochina, which is due to better economical status and industrialization. A more important concern should be the mass anti-parasitic drug use for control of liver fluke. In Laos, a tropical country next to Thailand, the same finding of vernutrition among the risk villagers is reported, and it is suggested that “the WHO dose pole is not recommended for distribution of praziquantel for the treatment of Opisthorchiasis in populations where being overweight is quite common”.[5]
