[The role of atopic background in the genesis of allergic manifestations in intestinal parasitoses].

The previous literature and personal observations showed the predominant role of the atopic background in the appearance of the allergic manifestation in the parasitic infestation and especially in giardiasis. The lot investigated was made of 52 patients with allergic manifestations, also infested with Giardia intestinalis or with Ascaris lumbricoides. The hereditary collateral and personal allergic antecedents and the clearly deficient histaminopexy (1/20) were present in 1/2 of the patients. Summation of the various parameters of atopic background shows its presence in about 2/3 of the patients investigated. Association of the clinical involvement of trophallergens was present in 1/2 of the patients. The results show that the allergic manifestation in the intestinal parasitoses have a multifactorial determination. The atopic background is predominant in their development. These manifestations are often a result of alimentary allergy due to the absorption of alimentary antigens through the enteral mucous membrane affected by the parasite.

Contributions to the study of gastric carcinogenesis.

Investigations were carried out on duodeno- and jejunogastric reflux, gastric juice acidity, microbial population and the concentration of nitrites in 199 subjects. In gastric cancer patients or those with gastric ulcer, chronic atrophic gastritis, stomach resection or more seldom with removal of the gallbladder, a significant increase over normal values of the pH, duodenogastric reflux, microbial flora contamination (especially intestinal) and nitrite concentration was found. In smokers the salivary nitrite concentration was greater than in non-smokers and in direct relationship to gastric concentrations. The parallelism of these alterations suggests a causative relation between them and their presence in diseases or conditions of notorious increased incidence in gastric cancer highlights the direction to be followed in the primary prophylaxis of this disease.
