          Abstract

          OBJETIVOS: Avaliar furazolidona, tetraciclina e omeprazol como tratamento de primeira linha para Helicobacter pylori em crianças com sintomas digestivos. MÉTODOS: Ensaio clínico aberto, prospectivo e consecutivo. O estudo incluiu pacientes acima de 8 anos com dispepsia funcional, dor abdominal funcional, anormalidades histológicas graves (metaplasia intestinal, atrofia gástrica ou linfoma do tecido linfóide associado às mucosas) ou úlcera péptica. A presença de H. pylori foi definida com base em exame histológico e teste da urease. O regime medicamentoso consistiu de um tratamento de 7 dias com omeprazol, tetraciclina (ou doxiciclina) e furazolidona duas vezes por dia. A erradicação foi avaliada através de endoscopia digestiva alta 2 meses após o tratamento (exame histológico e teste da urease). Avaliações clínicas posteriores foram realizadas 7 dias e 2 meses após o tratamento. RESULTADOS: Foram incluídos 36 pacientes (21 meninas/15 meninos). A idade variou de 8 a 19 anos (média de 12,94+2,89 anos). Na análise por intenção de tratar (n = 36), a taxa de erradicação foi de 83,3% (IC95% 77,1-89,5), ao passo que na análise por protocolo (n = 29), foi de 89,7% (IC95% 84,6-94,7). A adesão foi melhor quando se utilizou doxiciclina, mas as taxas de sucesso foram semelhantes para as duas tetraciclinas. Não houve nenhuma variável associada à falha no tratamento. Foram relatados efeitos colaterais em 17 pacientes (47,2%), principalmente dor abdominal (11/30,5%), náusea (sete/19,4%) e vômitos (cinco/13,9%). CONCLUSÃO: A terapia tripla com furazolidona e tetraciclina é uma alternativa de baixo custo para o tratamento da infecção pelo H. pylori.

          OBJECTIVE: To evaluate furazolidone, tetracycline and omeprazole as first line therapy for Helicobacter pylori in children with digestive symptoms. METHODS: Prospective and consecutive open trial. The study included patients older than 8 years old with functional dyspepsia, functional abdominal pain, severe histological abnormalities (intestinal metaplasia, gastric atrophy or mucosa-associated lymphoid tissue lymphoma) or peptic ulcer. H. pylori status was defined based both upon histology and rapid urease test. Drug regimen was a 7-day course of omeprazol, tetracycline (or doxycycline) and furazolidone twice daily. Eradication was assessed by upper endoscopy 2 months after treatment (histology and rapid urease test). Further clinical evaluation was done 7 days and 2 months after treatment. RESULTS: Thirty-six patients (21 female/15 male) were included. Age ranged from 8 to 19 years (mean 12.94+2.89 years). On intention-to-treat analysis (n = 36), eradication rate was 83.3% (95%CI 77.1-89.5) whereas in per-protocol analysis (n = 29), it was 89.7% (95%CI 84.6-94.7). Compliance was better when doxycycline was used, but the success rates were similar for the two tetracyclines. There was no variable associated with treatment failure. Side effects were reported in 17 patients (47.2%), mainly abdominal pain (11/30.5%), nausea (seven/19.4%) and vomiting (five/13.9%). CONCLUSION: Triple therapy with furazolidone and tetracycline is a low-cost alternative regimen to treat H. pylori infection.

          Classification and grading of gastritis. The updated Sydney System. International Workshop on the Histopathology of Gastritis, Houston 1994.

          The Sydney System for the classification of gastritis emphasized the importance of combining topographical, morphological, and etiological information into a schema that would help to generate reproducible and clinically useful diagnoses. To reappraise the Sydney System 4 years after its introduction, a group of gastrointestinal pathologists from various parts of the world met in Houston, Texas, in September 1994. The aims of the workshop were (a) to establish an agreed terminology of gastritis; (b) to identify, define, and attempt to resolve some of the problems associated with the Sydney System. This article introduces the Sydney System as it was revised at the Houston Gastritis Workshop and represents the consensus of the participants. Overall, the principles and grading of the Sydney System were only slightly modified, the grading being aided by the provision of a visual analogue scale. The terminology of the final classification has been improved to emphasize the distinction between the atrophic and nonatrophic stomach; the names used for each entity were selected because they are generally acceptable to both pathologists and gastroenterologists. In addition to the main categories and atrophic and nonatrophic gastritis, the special or distinctive forms are described and their respective diagnostic criteria are provided. The article includes practical guidelines for optimal biopsy sampling of the stomach, for the use of the visual analogue scales for grading the histopathologic features, and for the formulation of a comprehensive standardized diagnosis. A glossary of gastritis-related terms as used in this article is provided.

            American College of Gastroenterology guideline on the management of Helicobacter pylori infection.

            Helicobacter pylori (H. pylori) remains a prevalent, worldwide, chronic infection. Though the prevalence of this infection appears to be decreasing in many parts of the world, H. pylori remains an important factor linked to the development of peptic ulcer disease, gastric malignanc and dyspeptic symptoms. Whether to test for H. pylori in patients with functional dyspepsia, gastroesophageal reflux disease (GERD), patients taking nonsteroidal antiinflammatory drugs, with iron deficiency anemia, or who are at greater risk of developing gastric cancer remains controversial. H. pylori can be diagnosed by endoscopic or nonendoscopic methods. A variety of factors including the need for endoscopy, pretest probability of infection, local availability, and an understanding of the performance characteristics and cost of the individual tests influences choice of evaluation in a given patient. Testing to prove eradication should be performed in patients who receive treatment of H. pylori for peptic ulcer disease, individuals with persistent dyspeptic symptoms despite the test-and-treat strategy, those with H. pylori-associated MALT lymphoma, and individuals who have undergone resection of early gastric cancer. Recent studies suggest that eradication rates achieved by first-line treatment with a proton pump inhibitor (PPI), clarithromycin, and amoxicillin have decreased to 70-85%, in part due to increasing clarithromycin resistance. Eradication rates may also be lower with 7 versus 14-day regimens. Bismuth-containing quadruple regimens for 7-14 days are another first-line treatment option. Sequential therapy for 10 days has shown promise in Europe but requires validation in North America. The most commonly used salvage regimen in patients with persistent H. pylori is bismuth quadruple therapy. Recent data suggest that a PPI, levofloxacin, and amoxicillin for 10 days is more effective and better tolerated than bismuth quadruple therapy for persistent H. pylori infection, though this needs to be validated in the United States.

              Pharmacokinetics and pharmacodynamics of the tetracyclines including glycylcyclines.

              The pharmacokinetics of tetracyclines and glycylcyclines are described in three groups. Group 1, the oldest group, represented by tetracycline, oxytetracycline, chlortetracycline, demeclocycline, lymecycline, methacycline and rolitetracycline is characterized by poor absorption after food. Group 2, represented by doxycycline and minocycline, is more reliably absorbed orally, while group 3, represented by the glycylcycline tigecycline, is injectable only, with an improved antibacterial spectrum compared with the tetracyclines. Though incompletely understood, the pharmacodynamic properties of the tetracyclines and glycylcyclines are summarized.
