There was no association of milk-specific IgG or IgA with a reported history of a diagnosed gastrointestinal disorder [irritable bowel syndrome = 12/388 (3.0%) or inflammatory bowel disease = 4/388 (1.0%)], since none of these patients had high levels of cows milk-specific IgG or IgA. IgG levels than those with no milk-related gastrointestinal symptoms (= 198, = 0.02). Among the symptomatic subjects, those reporting dyspeptic symptoms had lower milk protein IgG levels than non-dyspeptics ( 0.05). However, dyspepsia was not associated with milk drinking (= 0.5). The association of high milk protein IgG levels with constipation was close to the level of statistical significance. Diarrhea had no association with milk protein IgG level (= 0.5). With regard to minor symptoms, flatulence and bloating (= 0.8), were not associated with milk protein IgG level. Milk protein IgA levels did not show any association with TTP-22 milk drinking or abdominal symptoms. The levels Ptgfr of milk protein IgA and IgG declined as the age of the subjects increased ( 0.004). CONCLUSION: Milk protein IgG but not milk IgA seems to be associated with self-reported milk-induced gastrointestinal symptoms. ( 0.05. RESULTS The levels of milk protein IgA and IgG antibodies declined as the age of the subjects increased, being least expensive in the oldest age group, and the age-related decrease was statistically significant with regard to milk protein IgG (ANOVA, 0.004; Table ?Table1).1). Age and personally estimated milk-related gastrointestinal problems showed no correlation (= NS, Spearman Rank). Males experienced higher milk protein IgA but not milk IgG levels in their sera than ladies (Mann-Whitney, = 0.04; Table ?Table1).1). Subjects drinking milk daily experienced higher levels of milk protein IgG in their sera than non-milk drinkers (Mann-Whitney, 0.001; Table ?Table1).1). The daily usage of milk was less TTP-22 frequent among subjects reporting gastrointestinal problems after drinking milk, but they experienced higher milk protein IgG levels than those who experienced no gastrointestinal symptoms (Table ?(Table1).1). Milk protein IgA levels did not display any association with milk drinking or abdominal symptoms (Table ?(Table11). Table 1 Data of the study group, the experienced symptoms and correlation of milk protein IgG and IgA levels with different guidelines (% of the study group)Mean IgG% (arbitrary models) 95% CI (lower-upper)= 0.5). Concerning small symptoms, flatulence and bloating (= 0.8, Mann-Whitney), were not associated with milk protein IgG level. Subjects reporting dyspeptic symptoms experienced lower milk protein IgG levels than non-dyspeptics ( 0.05). Furthermore, dyspepsia was not associated with milk drinking (= 0.5, Fishers exact test) or age (= 0.19, Spearman Rank). Milk protein IgG level was reduced subjects positive for antibodies to (= 76/386, 0.05 Mann-Whitney) although they drank milk more often than = 62/76, TTP-22 0.006 Mann-Whitney). However, the = 0.004, ANOVA), which may explain the result. Accordingly, the presence of antibodies in serum was connected inside a statistically significantly manner with a lower level of milk protein IgA antibodies (= 0.03, Mann-Whitney). There was no correlation between milk protein IgG or IgA antibodies and C/T-13910 genotype associated with adult type hypolactasia. Unexpectedly, none of them of these randomly picked subjects was screen-positive for celiac disease[16]. There was no association of milk-specific IgG or IgA having a reported history TTP-22 of a diagnosed gastrointestinal disorder [irritable bowel syndrome = 12/388 (3.0%) or inflammatory bowel disease = 4/388 (1.0%)], since none of these individuals experienced high levels of cows milk-specific IgG or IgA. Irritable bowel syndrome was reported less in the study group than in an average western populace (5%-10%) and inflammatory bowel disease more often than in an average western populace (0.1%)[19,20]. Conversation Milk protein IgG but not milk IgA seems to be associated with self-reported milk-induced gastrointestinal symptoms. The nature of these symptoms, however, is definitely unclear. There was a definite association of milk protein IgG with milk drinking in our study, supporting the look at that the presence of milk.
