Contribuição ao estudo da reação á tricofitina nas dermatofitoses

Abstract

Os autores investigaram a competência imunológica específica de 31 indivíduos portadores de dermatofitose, utilizando o antígeno tricofitina. Destes, 54,8% mostraram-se reatores à fase tardia dessa prova (48 h) nas seguintes proporções: tinea inguinale, 75%; tinea pedis, 61,5%; tinea unguium, 50% e tinea corporis, 20%. 62,5% dos casos apresentaram positividade à fase imediata (30 m) da reação. A associação entre essas reações revelou que, embora a maioria dos pacientes com reação imediata positiva apresentasse negatividade à reação tardia, 20,8% apresentaram positividade para as duas fases da reação. Dos pacientes não reatores à fase tardia, oito foram submetidos a outros testes cutâneos: PPD, estreptoquinase, candidina, vacínia e DNCB, verificando-se imunidade celular conservada em 75% dos casos. Estes resultados sugerem que, quando da utilização dessa prova na avaliação imunológica de pacientes com dermatofitose, deve-se considerar o estado imune geral do paciente, a presença de hipersensibilidade imediata e a localização da infecção.

Dermatophytosis: association between ABO blood groups and reactivity to the trichophytin

“…In our study we verified that 71.5% of the patients who manifested positive immediate reaction didn't develop delayed reaction confirming the results found in the literature 9,11,12,17 . The manifestation of the two reactions was verified in 28.5% of the patients, which suggests that mechanisms other than the immediate reaction could be involved in the non-response in the delayed phase to the trichophytin reaction.…”

“…In the present study, immediate reactions were verified in patients with T. rubrum (55.5%) and also in patients with T. mentagrophytes (33%). These results are similar to the found by GAMBORG-NIELSEN 7 and VILANI-MORENO & ARRUDA 17 , and they suggest that albeit the immediate reaction is more frequent in patients infected by T. rubrum, this can be shown in patients infected by other dermatophytes.…”

Study the Correlated Between Human Blood Groups and Body Mass Index for Children in Thi-Qar Province

“…Email: biomgzn.sci@uokufa.edu.iq when they found that phenotype O was the most common frequently group system, while the group system AB records the lowest percentage in the whole samples .The O, B, A and AB blood groups system percentages, were the follows: 35.4% , 33.2% , 22.5% and 8.7% in the respectively.Therefore this results refers to the a high factor gene frequencies for B + and O + blood groups systems for children in Thi-Qar province, also this result agreement with a high population which recorded a high frequency of B + and O + blood groups systems than very low number and percentage which recorded for Oblood group system [11].This study recorded a highly percentage for urban 72.22% than the rural 27.78%., this resut may be refers to most of patients were from nearby areas.This result disagreement with [12], when they recorded highly number and percentage of O,A,B and AB in rural areas, which were in respectly 20.2,80.5,79.4 and 80.1.Also this study showed no significant in relationship between ABO blood groups and infection with parasites.Then this result agreement with [13], when they found there was no significant relationship between ABO blood groups and malaria in our population, this could be due to various demographic reasons.Although there are no significant between the gender and ABO blood groups system.This result disagreement with [14], when they found there was an association between distribution of fingerprint patterns, blood group and gender in Maiduguri and thus prediction of the gender and the blood group of a person is possible based on fingerprint pattern.Overall, this study recorded no significant between the body mass index (BMI) and ABO blood group systems.Therefore this result disagreement with [15], when they found the relationship between the ABO blood groups systems and the BMI at the first menarche and hypertension are not singly risk factors for infected with breast cancer, but probably combination of them can increases breast cancer incidence.Besides, this study showed , there are relationship between the ABO blood groups systems and infected with diseases.Therefore this result disagreement with [16],when the auther found a higher percentage of patients belonging to the blood group A infected by Trichophyton rubrum, therefore these results suggest that there is no significant or statistical evidence that these individuals are more susceptible to dermatophytosis.Also there were found no significant between the gender and the body mass index in this study. This result disagreement with [17], they found a significant positive correlation was observed between BMI-BF%, in the males were (r =0.75, p < 0.01; SEE = 4.17) and in the females were (r = 0.82, p < 0.01; SEE = 3.54) of all ages groups.…”

Experimental dermatophytosis in hamsters inoculated with Trichophyton mentagrophytes in the cheek pouch

“…Added to this, observations related to human dermatophytosis are found; it has been suggested that in patients with dermatophytosis, the negative reaction to trichophytin would be related to development of IgE antibodies; these antibodies could deplete available fungal antigens by binding to them, or form complexes that would affect the manifestation of DH response 21,22 .…”
