ABO blood group distributions in diarrhoea cases including cholera in Calcutta
Insights
Cholera patients in Calcutta showed a significant association with blood group O. However, Vibrio parahaemolyticus-induced diarrhea did not demonstrate a similar link with ABO blood groups.
Area of Science:
- Epidemiology
- Medical Microbiology
- Immunogenetics
Background:
- The ABO blood group system is a well-known human polymorphism.
- Previous studies have suggested associations between ABO blood groups and infectious diseases.
- Understanding these associations can aid in disease management and prevention strategies.
Purpose of the Study:
- To investigate the potential association between ABO blood groups and cholera.
- To determine if ABO blood groups are associated with diarrhea caused by Vibrio parahaemolyticus.
Main Methods:
- A double-blind study was conducted involving 210 cholera patients, 44 patients with Vibrio parahaemolyticus-induced diarrhea, and 148 control subjects.
- ABO blood group typing was performed on all participants.
- Statistical analysis was used to compare the distribution of blood groups among the groups.
Main Results:
- A statistically significant difference in the prevalence of blood group O was observed between cholera patients and the control group.
- No significant association was found between Vibrio parahaemolyticus-induced diarrhea and ABO blood groups.
Conclusions:
- Blood group O may be a risk factor for cholera.
- There is no apparent association between ABO blood groups and Vibrio parahaemolyticus-induced diarrhea.
Abstract:
A double blind study on determination of ABO blood groups of 210 cholera patients, 44 diarrhoea cases due to Vibrio parahaemolyticus, and 148 diarrhoea cases from whom no vibrios could be isolated (control group), was conducted in Calcutta. A statistically significant difference was found in blood group 'O' when comparison was made between control and cholera groups. No significant association was, however, notices between V. parahaemolyticus-induced diarrhoea and ABO blood groups.
