The non‐secretor phenotype was significantly associated with the occurrence of renal scarring among patients with recurrent pyelonephritis. Girls (n= 77) with recurrent pyelonephritis were followed from the first known episode of infection for up to twelve years with repeated radiological investigations. They were divided into two categories: those with renal scars (n= 35) and those who did not develop scars (n= 42). There was a significant over‐representation of non‐secretors among the patients with scarring, (14/35, 40%) compared to the healthy controls (21.8%, P < 0.05). The frequency of non‐secretors among the girls who did not develop scars in spite of repeated episodes of acute pyelonephritis was not significantly different from the healthy controls (9/42, 21%, n.s.). This study provides a basis for analysis of the influence of secretor state on host‐parasite interaction in the urinary tract.

“…Anthropologists have used the ABO blood types as a guide to the development of modern humans. Many diseases, particularly digestive disorders, cancer, and infection, show preferences among the ABO blood types [3][4][5][6][7] . These preferences are not generally understood or appreciated by physicians or the general population.…”

The aim of this study was to investigate if there is an association between ABO blood group and severity of chronic periodontitis. Data were collected from 161 chronic periodontitis patients. Medical history, dental history, and periodontal parameters (such as probing depth, clinical attachment loss, and distance from cemento-enamel junction to gingival margin, furcations, and mobility and missing teeth) were recorded. Blood samples were analyzed to determine blood group and Rhesus factor. The mean age of the study sample was 34.5 years (± 13); there was no significant difference among ABO blood groups (p = 0.3). Gender distribution was also similar among groups. Periodontal parameters were compared among all ABO groups except for the AB group owing to its small sample size. Mean clinical attachment loss (CAL) and mean proportion of sites with CAL ≥ 3 mm were the greatest among group B, and the differences among groups were significant (p < 0.05). Other clinical parameters were not significantly different among groups. Significant relationships were determined between ABO blood type and the severity of chronic periodontitis. Patients with group B were found to be at greater risk of developing more severe form of periodontitis. Further, long-term studies with larger sample sizes are needed to confirm this conclusion.
