ABSTRACT

AIM: The present study aimed to evaluate if the oral cavity of chronic periodontitis patients can harbor Helicobacter pylori after systemic eradication therapy. MATERIALS AND METHODS: Samples of 30 patients (15 with gingivitis and 15 with chronic periodontitis) positive for H. pylori in the stomach were evaluated. Samples were collected 3 months after triple systemic antibiotic therapy from saliva, microbiota from the dorsum of the tongue, supra- and sub-gingival plaque as well as gastric biopsies. DNA of each sample was extracted by the boiling method and used as a template in polymerase chain reaction with the primers JW22/23. RESULTS: Eighteen patients (60%) harboured H. pylori in their mouths. Five patients (16.6%) were positive in saliva, two (6.6%) on the dorsum of the tongue, nine (30%) in supra-gingival plaque, 14 (46.6%) in sub-gingival plaque and three (10%) in the stomach. There was no statistically significant difference between study groups. CONCLUSION: Eradication of H. pylori after therapy was more effective for the stomach than for the mouth (p<0.001). Mouths of patients with gingivitis or with chronic periodontitis, who are positive for H. pylori in their stomachs, may be considered as reservoirs of these bacteria.

ABSTRACT

Informações quanto à recorrência da infecção por H. Pylori (Hp) são restritas. A erradicação da bacteriaresulta na cura da doença ulcerosa péptica (DUP) na ausência de antiinflamatório. a DUP, todavia, recidiva com a reinfecção. Quanto maior a falha na erradicação maior a recorrencia, que envolve reinfecção e recrudescência. Objetivo: Avaliar o índice de recorrência do Hp ao longo do período pós-erradicação e confrontar os resultados do serviço com os observados em outros centros. Casuística e método: estudo retrospectivo longitudinal de pacientes com DUP infectados pelo Hp, atendidos de março de 1993 a agosto de 2003 no Ambulatório de Dispepsia da Disciplina e que receberam integralmente esquema para erradicação da bactéria. Foi feita reavaliação clínica, controle endoscópico com pesquisa de Hp, aos três , seis e 12 meses da erradicação e a partir de então, anualmente, por até oito anos. Para análise dos dados empregou-se o teste do qui-quadrado. Resultados: A 422 pacientes forneceram-se 609 tratamentos. Ao longo de oito anos, houve 633,4 pacientes-ano, o que denota o grande abandono de acompanhamento. A taxa de sucesso em três meses, seis meses e em um ano do tratamento foi de 70,3por cento,61,9por cento e de 54,2por cento, respectivamente. Considerando esquema com a associação do IBP, amoxilina e claritromicina (esquema mais eficaz dentre os utilizados) e somente a erradicação pela primeira vez, a taxa de sucesso foi de 85,3por cento, 81,0por cento, e de 74,3 em três meses, seis meses e em um ano após a erradicação, respectivamente. Conclusões:1) a taxa de sucesso de erradicação do Hp depende do intervalo de tempo em que se define o controle de cura, sendo o de três meses o mais adequado em relação ao de um mês; 2) há melhor resposta terapêutica na primeira tentativa de erradicação com esquema IBP, amoxicilina e claritromicina; 3) a positivação da pesquisa de Hp ocorre principalmente no primeiro ano após a erradicação; 4) quanto menor a falha terapêutica no primeiro ano, menores as taxas de recorrência ao longo dos anos; 5) de forma geral, a recorrência da infecção por Hp é de 9,6por cento ao ano (média ao longo de oito anos); considerando-se a associação IBP, amoxicilina e claritromicina, a média cai para 6,0por cento no mesmo período

ABSTRACT

Helicobacter pylori is an important gastrointestinal pathogen associated with gastritis, peptic ulcers, and an increased risk of gastric carcinoma. The oral cavity has been indicated as a possible H. pylori reservoir, and may therefore be involved in the reinfection of the stomach which sometimes follows treatment of H. pylori infection. The objective of the present study was to evaluate the prevalence of H. pylori as detected by polymerase chain reaction (PCR) in the oral cavity of periodontitis patients testing positive for this bacterium in the stomach. Thirty adult patients with alterations of the superior digestive tract, testing urease positive after endoscopy and biopsy, were selected. A full-mouth periodontal examination was performed in every patient and the subjects were allocated to two groups: gingivitis (15 patients) and chronic periodontitis (15 patients). Plaque and saliva samples collected from each patient were stored in 0.5 ml of TE buffer. DNA was extracted from the samples by the boiling method and was evaluated for the presence of H. pylori using the PCR method. JW 22/23 primers were used. The DNA of ATCC H. pylori 43629 (positive control) and water (negative control) were used for controlling the reactions. Of the 30 evaluated patients, 13 (43.3%) harbored H. pylori in the mouth. The bacterium was not found on the dorsum of the tongue of any patient, but was found in saliva in three patients (10%), in the supragingival plaque in six patients (20%), and in the subgingival plaque in eight patients (26.6%). The presence of H. pylori was similar in the gingivitis and chronic periodontitis groups. In conclusion, a high percentage of patients harbored H. pylori in their mouth. The bacterium was detected in saliva, supragingival and subgingival plaque, suggesting that these sites may be considered reservoirs for H. pylori in urease-positive patients.

ABSTRACT

A maioria dos autores executa controle de erradicaçäo após um mês do término do tratamento, todavia, avolumam relatos de taxas crescentes de recorrência da infecçäo pelo Hp na mewdida em que aumenta o período de avaliaçäo pós-tratamento. Foi avaliada a evoluçäo quanto à infecçäo pelo Hp em adultos portadores de úlcera peptica (UP) que presentaram pesquisa negativa após 3 meses do trataemtno de erradicaçäo. O diagnóstico de UP baseou-se na endoscopia digestiva alta e histologia, no caso de lesäo gástrica. A pesquisa do Hp foi realizada em duas biópsias endoscópicas de antro gástrico, através do teste da urease ou da análise histológica. No periódo de março/93 a setembro/97, 57 dos 92 pacientes que receberam integralmente o tratamento de erradicaçäo retornaram para controle após 3 meses do término do tratamento, sendo que 21 permaneceram infectados pelo Hp. Os 36 pacientes Hp negativo foram avaliados trimestralmente durante 15 meses, para determinaçäo de infecçäo pelo Hp. Dos 36 pacientes avaliados, 11 mantiveram-se Hp negativo, 11 sofreram positivaçäo e 14 pacientes näo completaram o acompanhamento. O indice de recorrência da infecçäo aos 6, 9, 12 e 15 meses do término do tratamento foi de 3,3 por cento, 4,5 por cento, 15,8 por cento e 50 por cento respectivamente. A baixa taxa de erradicaçäo provavalmente implicou a elevada recorrência, sendo imperativo que os tratamentos em nosso meio atinjam melhores níveis de eficácia

ABSTRACT

Pacientes portadores de hepatopatia crônica de etiologia alcoólica, quando tratados com colchicina durante período de 12 meses, apresentaram índices de recuperaçäo dos níveis plasmáticos de albumina e protrombina significantemente superiores aos de pacientes fazendo uso de placebo. Entretanto, nenhuma diferença estatística pôde ser observada entre os dois grupos quanto à taxa de mortalidade e de admissäo hospitalar dos pacientes, no período estudado. OBJETIVO. Analisar a evoluçäo clínica e os níveis plasmáticos de albumina, pré-albumina, transferrina e protrombina em portadores de hepatopatia crônica alcoólicaem uso de colchicina ou placebo, durante período de 12 meses. MÉTODOS. em um estudo duplo-cego, 41 pacientes portadores de hepatopatia crônica de etiologia alcoólica foram randomizados para receber placebo (20 pacientes) ou colchicina (21 pacientes), avaliando sua evoluçäo clínica e dos níveis das proteínas plasmáticasalbumina, pré-albumina e transferrina por imunodifusäo radial e do tempo e atividade de protrombina pelo método de Quick modificado. RESULTADOS. Apenas 7,3 por cento dos pacientes näo completaram os 12 meses de seguimento do estudo. Näo se observaram diferenças significantes entre os grupos, no que se refere à taxa de mortalidade ou ao número de internaçöes hospitalares. Quanto aos níveis séricos protéicos, observaram-se valores significantemente superiores no grupo da colchicina do que no grupo placebo, para as médias das variaçöes percentuais dos níveis de albumina (17,9 por cento colchicina x 3,6 por cento placebo, p<0,05) e da atividade de protrombina (19,2 por cento colchicina x 2,1 por cento placebo, p<0,05). As variaçöes dos valores da pré-albumina, apesar de apresentarem o mesmo comportamento observado para os níveis de albumina e protrombina, näo atingiram significância estatística. Já os níveis de transferrina sérica näo diferiram entreos dois grupos. CONCLUSÄO. Estes resultados sugerem que a administraçäo de colchicina tenha um efeito benéfico sobre os níveis de proteínas plasmáticas nos pacientes com hepatopatia crônica de etiologia alcoólica.

ABSTRACT

UNLABELLED: Patients with alcoholic chronic liver disease when treated with colchicine during a 12 month-period improved significantly the plasmatic levels of albumin and prothrombin when compared with a similar group of patients who took placebo. No differences in the mortality rate and in number of patients admitted at the hospital could be detected among those groups during this period. PURPOSE: To evaluate the clinical outcome and the plasmatic levels of albumin, pre-albumin, prothrombin and transferrin in patients presenting alcoholic chronic liver disease taking colchicine or placebo, during a 12-month period. METHODS: In a double-blind, randomized, controlled trial, 41 patients with alcoholic chronic liver disease were assigned to either placebo (20 patients) or a colchicine (21 patients) treatment group, assessing their clinical course (mortality rate and hospital admission) and plasmatic protein levels during a 12-month period. Albumin, pre-albumin and transferrin plasmatic levels were assessed through a immunodiffusion radial method and prothrombin time and activity was assessed by a one stage Quick modified method. RESULTS: At the end of the trial, only 7.3% of the patients were lost during follow-up. No statistical differences could be found in mortality and number of patients admitted at the hospital among placebo and colchicine groups. Comparatively to the placebo group, a significant increase in the mean of percentage variation was found in patients of the colchicine group for serum albumin levels (17.9% colchicine x 3.6% placebo, p < 0.05) and for prothrombin activity (19.2% colchicine x 2.1% placebo, p < 0.05). A similar pattern of response was found in pre-albumin serum levels, but such differences were not statistically different. No differences were found in serum transferrin levels among both groups. CONCLUSION: These results suggest that colchicine intake has a positive effect on plasmatic protein levels in patients with alcoholic chronic liver disease.

ABSTRACT

We have investigated the effects of nontoxic doses of vitamin A on the hepatic contents of collagen and sulfated glycosaminoglycans (SGAGs) in rats chronically treated with CCl4. When the animals were treated with this retinoid before the intoxication with CCl4, liver collagen level was significantly reduced as compared with that in rats that received only CCl4 (3.31 +/- 0.40 vs 5.00 +/- 0.61 mg/gm wet liver, mean +/- SD, respectively), although no significant differences were found for the relative proportion of type III collagen related to type I collagen. The absolute increment in the total amount of liver SGAG in the vitamin A--pretreated group was followed by a more important increase in the concentration of dermatan sulfate as compared with the CCl4 group (dermatan sulfate-to-heparan sulfate ratio: 1.15 for the CCl4 group vs 1.70 for the vitamin A--pretreated group). A significant proportion of the dermatan sulfate from this last group was of higher molecular weight when compared with the dermatan sulfate found in the liver of rats that received only CCl4. Our results indicate that the pretreatment with vitamin A modifies hepatic collagen and SGAG deposition and can inhibit or delay the development of liver cirrhosis in rats chronically treated with CCl4. We speculate that this effect could be due to the changes in the fat-storing (Ito) cells phenotype induced by vitamin A.
