Castro, Cleudson;Prata, Aluizio;
Revista da Sociedade Brasileira de Medicina Tropical , 2000, DOI: 10.1590/S0037-86822000000500003
Abstract: xenodiagnoses were performed every 3 hours using 10 triatoma infestans 3rd instar for 24 to 72 hours, in 18 chronic chagasics with positive serology and/or xenodiagnosis. there was no statistically significant difference in the positivity of assays performed during the day (9:00 to 18:00h) compared to those performed at night (21:00 to 6:00h), (c2 = 0.1526 p = 0.696). xenodiagnosis was performed in ten of the patients for 13 successive days but there was no periodicity detected in the positive assays.

Abstract: Foram estudados prospectivamente 190 chagásicos, do ponto de vista clínico, eletrocardiográfico e abreugráfico do es fago, no período médio de 13 anos, sendo encontrados 108 (56,8%) com a forma clínica inalterada, 72 (37,9%) com doen a progressiva e 10 (5,3%) nos quais houve normaliza o do eletrocardiograma. Nos 72, em que a doen a progrediu, 39 desenvolveram cardiopatia ou agravaram a já existente, 32 evoluíram para, ou pioraram o megaes fago prévio e, 12 evoluíram para colopatia ou agravaram a já existente. Dentre os 72, 11 tinham formas clínicas associadas. A evolu o da cardiopatia foi maior no sexo masculino 29,6% (21/71) que no feminino 15,1% (18/119), p = 0,015. Houve 19 casos novos de cardiopatia e 20 agravaram a cardiopatia prévia. A incidência de megaes fago foi 14,9% (23/154) e nove agravaram o megaes fago já existente. A evolu o da colopatia foi maior no sexo feminino 9,2% (11/119), que no masculino 1,4% (1/71), p =0,026.

Abstract: introduction: since 1970, lengthening of the rectosigmoid has been suspected to be a solitary manifestation of chagas colopathy. methods: to test this hypothesis, opaque enema was administered on 210 seropositive and 63 seronegative patients, and radiographs in the anteroposterior and posteroanterior positions were examined blind to the serological and clinical findings. the distal colon was measured using a flexible ruler along the central axis of the image from the anus to the iliac crest. results: dolichocolon was diagnosed in 31 (14.8%) seropositive and 3 (4.8%) seronegative patients. the mean length was 57.2 (±12.2)cm in seropositive patients and 52.1 (±8.8)cm in the seronegative patients (p = 0.000), that is, the distal colon in chagas patients was, on average, 5.1cm longer. seropositive female patients presented a mean length of 58.8 (±12.3)cm, and seronegative female patients presented 53.2 (±9.1)cm (p = 0.002). seropositive male patients had a mean length of 55 (±11.6)cm, and seronegative male patients had 49.9 (±7.8)cm (p = 0.02). among 191 patients without megacolon and suspected megacolon, the mean length was 56.3 (±11.6)cm in seropositive individuals and 52 (±8.8)cm in seronegative patients (p = 0.003). among individuals with distal colon >70cm, there were 31 chagas patients with mean length of 77.9 (±7.1)cm and three seronegative with 71.3 (±1.1)cm (p = 0.000). among 179 with distal colon <70cm, seropositive individuals had a mean length of 53.6 (±8.8)cm, and seronegative patients had 51.2 (±7.8)cm (p = 0.059). serological positive women had longer distal colon than men (p = 0.02), whereas the mean length were the same among seronegative individuals (p = 0.16). conclusions: in endemic areas of brazil central, solitary dolichocolon is a radiological chagas disease signal.

Revista da Sociedade Brasileira de Medicina Tropical , 2010, DOI: 10.1590/S0037-86822010000500018
Abstract: introduction: a radiological study on the colon of patients from an endemic chagas disease zone was conducted using the simplified opaque enema technique of ximenes et al. methods: the study involved 291 individuals with a mean age of 48.8(±12.5) years-old, of whom 222 were seropositive for chagas disease. anteroposterior, posteroanterior and left lateral view radiographs were analyzed by visual inspection and measurement of the largest rectal and sigmoid diameters. results: from the visual inspection, megacolon was diagnosed in 14 (6.3%) chagas disease patients. the mean diameter of the rectal ampulla among the chagas patients was 6.3 (±1.0)cm, similar to the measurement in non-chagas individuals: 6.2 (±1.0) cm (p= 0.391). the mean sigmoid loop diameter in the chagas patients was 5 (±1.6)cm, which was larger than among the non-chagas individuals: 4.4 (±0.8)cm (p= 0.001). conclusions: excluding the evident and probable megacolon cases, the chagas disease population continued to present a significantly larger mean sigmoid diameter than that observed among non-chagas individuals (p= 0.003).

Abstract: during 13 years, 190 individuals with chagasic infection were submitted to clinical and parasitological examinations to investigate the relationship between parasitemia and the evolution of chronic chagasic infection. fifty-six patients with positive xenodiagnosis and 134 with negative exams were compared from 1988 to 91, it was found that 22 (39.3%) and 50 (37.3%), respectively, presented disease progression. the parasitemia was stratified into high, medium and low and the relation with the disease evolution showed that 5 (62.5%), 10 (41.7%) and 57 (36.1%), respectively, presented progressive disease, though without a statistically significant difference (p>0.05). when 20 patients with persistent parasitemia in 1976/91, were compared with 59 with negative xenodiagnosis, a progressive evolution was observed in 6 (30%) and 17 (28.8%), respectively. comparing six patients with high parasitemia and 59 with negative exams, it was verified that 3 (50%) and 17 (28.8%), respectively, showed progressive disease, but this was not statistically significant, (p>0.05). mean age with high, medium and low parasitemia were 39.6, 45.3 and 41.5 years, respectively, (p>0.05). mean age in patients showing progressive, unaltered and regressive evolution was 46.4, 39.8 and 32.6 years, respectively, with a statistically significant difference between progressive and regressive evolution (p<0.05). it is suggested that high parasitemia did not have an influence on the evolution of the chronic infection.
