RESUMO

OBJECTIVE: To identify the occurrence of surgical site infection (SSI) and its risk factors in patients undergoing colon surgery in a tertiary hospital located in the countryside of the state of São Paulo. METHOD: Retrospective cohort study, with collection of information contained in the medical records of patients undergoing colon surgery in the period between January 2010 and December 2013. The studied variables were the possible risk factors related to the patient, to demographic characteristics and the surgical procedure. RESULTS: In total, were evaluated 155 patients with an overall SSI incidence of 16.7%. A statistically significant association was found both in the univariate as in the multivariate analysis between the SSI and the following variables: male gender, Charlson index and mechanical bowel preparation. CONCLUSION: The understanding of health professionals about the factors that influence the incidence of SSI in colon surgery may contribute to the quality of care provided to surgical patients, from effective actions to minimize the risk of infections.

RESUMO

Histology is the gold standard for diagnosing acute rejection and hepatitis C recurrence after liver transplantation. However, differential diagnosis between the two can be difficult. We evaluated the role of C4d staining and quantification of hepatitis C virus (HCV) RNA levels in liver tissue. This was a retrospective study of 98 liver biopsy samples divided into four groups by histological diagnosis: acute rejection in patients undergoing liver transplant for hepatitis C (RejHCV+), HCV recurrence in patients undergoing liver transplant for hepatitis C (HCVTx+), acute rejection in patients undergoing liver transplant for reasons other than hepatitis C and chronic hepatitis C not transplanted (HCVTx-). All samples were submitted for immunohistochemical staining for C4d and HCV RNA quantification. Immunoexpression of C4d was observed in the portal vessels and was highest in the HCVTx- group. There was no difference in C4d expression between the RejHCV+ and HCVTx+ groups. However, tissue HCV RNA levels were higher in the HCVTx+ group samples than in the RejHCV+ group samples. Additionally, there was a significant correlation between tissue and serum levels of HCV RNA. The quantification of HCV RNA in liver tissue might prove to be an efficient diagnostic test for the recurrence of HCV infection.

RESUMO

BACKGROUND: Pregnancy anemia remains as a public health problem, since the official reports in the 70's. To guide the treatment of iron-deficiency anemia in pregnancy, the haemoglobin concentration is the most used test in spite of its low accuracy, and serum ferritin is the most reliable test, although its cutoff point remains an issue. METHODS/DESIGN: The aim of this protocol is to verify the accuracy of erythrocyte indices and serum ferritin (studied tests) for the diagnosis of functional iron-deficiency in pregnancy using the iron-therapy responsiveness as the gold-standard. This is an ongoing phase III accuracy study initiated in August 2011 and to be concluded in April 2013. The subjects are anemic pregnant women (haemoglobin concentration < 11.0 g/dL) attended at a low-risk prenatal care center in the Northeast of Brazil. The sample size (n 278) was calculated to estimate sensitivity of 90% and 80% of specificity with relative error of 10% and power of 95%. This study has a prospective design with a before-after intervention of 80 mg of daily oral iron during 90 days and will be analyzed as a delayed-type cross-sectional study. Women at the second trimester of pregnancy are being evaluated with clinical and laboratorial examinations at the enrollment and monthly. The 'responsiveness to therapeutic test with oral iron' (gold-standard) was defined to an increase of at least 0.55 Z-score in haemoglobin after 4 weeks of treatment and a total dose of 1200 mg of iron. At the study conclusion, sensitivities, specificities, predictive values, likelihood ratios and areas under the ROC (Receiver Operating Characteristic) curves of serum ferritin and erythrocyte indices (red blood cell count, haematocrit, haemoglobin concentration, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, red blood cell distribution width, reticulocyte count) will be tested. The compliance and adverse effects are considered confounding variables, since they are the main obstacles for the iron-therapy responsiveness. DISCUSSION: This study protocol shows a new approach on iron-deficiency anemia in pregnancy from a functional point of view that could bring some insights about the diagnostic misclassifications arising from the dynamic physiologic changes during the gestational cycle. TRIAL REGISTRATION: WHO International Clinical Trials Registry Platform U1111-1123-2605.

RESUMO

Epidemiological data clearly indicate a link between hepatitis C virus (HCV) and altered glucose homeostasis. Objective: To evaluate the response of treatment with direct antiviral agents (DAAs) on metabolic variables of patients with hepatitis C. Methods: Observational, cross-sectional study in a sample of patients with hepatitis C starting therapy with DAAs followed on the hepatology division of Federal University of Rio de Janeiro State. Data were collected in two stages: before the start of therapy and between 12 and 52 weeks after obtaining the sustained virological response. Results: In the baseline assessment of the 97 patients selected, 19.3% were obese, 38.6% were overweight, 50% were hypertensive, 43.8% were pre-diabetic, 12.5% were diabetic, 31.2% were dyslipidemic, and 21.8% had metabolic syndrome. There was an increase in total cholesterol and LDL levels (p < 0.001), and a non-significant reduction in blood glucose, glycated hemoglobin, insulin, and HOMA-IR levels after treatment. In the post-treatment, there was a reduction in fibrosis (p = 0.016), with a reduction in the levels of GGT, AST, and ALT (all with p < 0.001), as well as in the FIB4 and APRI scores (both with p < 0.001) and in the degree of fibrosis evaluated by elastography represented in kPa (p = 0.006). The blood glucose level was higher in patients with steatosis (p = 0.039) after treatment. There was a positive pre-treatment correlation between the degree of fibrosis (kPa) and FIB4 (r = 0.319, p = 0.004), APRI (r = 0.287, p = 0.010), and the NAFLD score (r = 0.275, p = 0.016). Conclusion: Patients with hepatitis C had a high prevalence of metabolic disturbance in the pre-treatment phase, but the therapy did not show beneficial effects, especially on glucose metabolism.

RESUMO

UNLABELLED: Hepatitis C virus (HCV) is an important factor contributing to morbidity and mortality in patients co-infected with HIV and HCV. In addition, liver biopsy is an important tool in the clinical management of these patients. Although liver biopsy is controversial, it is recommended for all patients. Data regarding the clinical and histological characteristics of these patients are scarce not only in Brazil but in Latin America as a whole. With the goal of better understanding these characteristics and the benefit of liver biopsy indications in this disease setting, data collected from 234 patients followed from 1996 to 2004 at Casa da AIDS, São Paulo, were analyzed. The following variables were extracted from the patients' medical files at the time of liver biopsy: sex, age, hepatitis C infection risk factors, hepatitis C infection duration, ALT levels, CD4+ T cell counts, history of alcohol abuse, history of antiretroviral therapy, HCV genotype, and liver histological alterations. CONCLUSIONS: 1 - Hepatitis C virus 1 and 3 were the most frequently identified genotypes and were diagnosed in 72% and 25.5% of cases respectively; 2 - Structural liver alterations were found to be mild or absent in 48.2% (113/234) of the analyzed patients; 3 - Fifty-three patients (23%) had normal ALT levels and 4 - Significant liver architectural changes (F2-F3) were evident in 22.5% of the patients with normal ALT levels.

RESUMO

Although hepatitis C is mainly hepatotropic, some studies suggest that hepatitis C virus (HCV) infects peripheral blood mononuclear cells (PBMC), using them as a reservoir, which might contribute to the development of resistance to treatment. Fifty-four hepatitis-C patients, who had been submitted to treatment, were selected. Blood samples were collected on the same day for the detection of HCV RNA in serum and PBMC by PCR, using the Amplicor HCV 2.0 assay (Roche Diagnostics). HCV genotyping was performed using the INNO-LiPA HCV kit (Versant, Bayer Diagnostics). HCV RNA was detected in both serum and PBMC in 35 (64%) patients and no RNA in 16 (29.6%). Disagreement between the serum and PBMC results was observed for three patients (5.6%), with HCV RNA being detected in PBMC but not in serum. Four months later, new serum and PBMC samples were collected from one of these patients and HCV RNA was detected in both samples, showing that PBMC can reveal signs of a lack of response to treatment. We conclude that the absence of HCV in the serum of patients with chronic hepatitis C by the end of treatment does not mean that there is no circulating virus. HCV in mononuclear cells may be an indicator of the persisting infection.

RESUMO

Candida dubliniensis is a new, recently described species of yeast. This emerging oral pathogen shares many phenotypic and biochemical characteristics with C. albicans, making it hard to differentiate between them, although they are genotypically distinct. In this study, PCR (Polymerase Chain Reaction) was used to investigate the presence of C. dubliniensis in samples in a culture collection, which had been isolated from HIV-positive and HIV-negative patients with oral erythematous candidiasis. From a total of 37 samples previously identified as C. albicans by the classical method, two samples of C. dubliniensis (5.4%) were found through the use of PCR. This study underscores the presence of C. dubliniensis, whose geographical and epidemiological distribution should be more fully investigated.

RESUMO

Hepatitis C virus infection evolves progressively persisting in the majority of patients (85%). Most patients have high ALT (alanine aminotransferase) levels and approximately 25% normal ALT. The latter are usually female and there is no association between genotype and severity of hepatic lesion. Histologic analysis usually shows small lesion and absence or low amount of fibrosis, despite cirrhosis having been reported. Aiming at assessing prevalence, demographic, genotypical and anatomopathological characteristics in patients with normal ALT levels, we have carried out a study of 68 chronic hepatitis C patients between January 1997 and April 2000. There was a prevalence of 13.8% chronic hepatitis C patients with normal ALT levels, 45.6% of which were male and 54.4% female, the mean age being 38 +/- 13 years. We found a predominance of genotype 1 in 84.7% of the patients, genotype 2 in 6.8% and genotype 3 in 10.7%. In 52.9% of the cases liver biopsies revealed liver reaction, periportal activity score 0-1 was observed in 85.3% of the patients and score 2-4 was seen in 14.7%. Structural activity score 0-1 was seen in 73.5% of the patients and score 2-4 in 26.5% of them. Periportal activity > or = 2 and structural activity > 1 was seen in 29%, but steatosis was not seen in 73.5%. Our results suggest the need to revisit for liver biopsy practice in patients with chronic hepatitis C and normal transaminases.

RESUMO

INTRODUCTION: in Brazil, chronic hepatitis C in patients coinfected with the human immunodeficiency virus (HIV) is treated with pegylated interferon (Peg-IFN) and ribavirin (RBV). However, few studies have evaluated the effectiveness of this treatment in this particular population. The identification of the factors that predict sustained virological response (SVR) under current clinical practice would enable clinicians to more accurately estimate the probability of achieving an SVR and therefore utilize the appropriate therapeutics, especially in the era of direct-acting antiviral (DAA) agents. AIMS: the primary aim of our study was to determine the SVR rate under current clinical practice. The secondary aims were as follows: (1) to determine the factors before and during treatment that predict SVR; and (2) to identify the causes of treatment interruption. METHODS: within a cohort of HIV/hepatitis C virus (HCV)-coinfected patients in Brazil, we performed a retrospective analysis of those individuals treated with Peg-IFN and RBV. RESULTS: among the 382 analyzed patients, SVR was observed in 118 [30.9% (95% confidence interval (CI): 26.3-35.8)], which included 25.9% (75/289) of the patients with genotypes 1 and 4 and 48.2% (41/85) of those with genotypes 2 and 3. After multivariate analyses the independent positive predictors for SVR after treatment for chronic hepatitis C with Peg-IFN and RBV were: absence of an AIDS-defining illness (p=0.001), HCV viral load lower than 600,000IU/mL at the onset of treatment (p=0.003), higher liver enzyme levels (p=0.039) at baseline, infection with genotypes 2 or 3 (p=0.003), and no transient treatment interruption (p=0.001). The treatment was interrupted in 25.6% (98/382) of the patients because of adverse events (11.3%, 43/382), virologic failure (7.8%, 30/382), and dropout (6.5%, 43/382). The main adverse events were cytopenia and psychiatric disorders. CONCLUSIONS: in our Brazilian case series, the SVR rate under current clinical practice conditions was similar to that reported in other studies. There was a correlation between an SVR and being infected by genotypes 2 and 3, low viral load, high ALT levels at the onset of treatment, and absence of an AIDS-defining illness. Cytopenia and psychiatric disorders were the major causes of treatment interruption. Efforts should be focused on optimizing management of side effects and counseling to improve adherence and to keep patients on treatment.

RESUMO

We examined the association between IL28B single-nucleotide polymorphism rs12979860, hepatitis C virus (HCV) kinetic, and pegylated interferon alpha-2a pharmacodynamic parameters in HIV/HCV-coinfected patients from South America. Twenty-six subjects received pegylated interferon alpha-2a + ribavirin. Serum HCV-RNA and interferon concentrations were measured frequently during the first 12 weeks of therapy and analyzed using mathematical models. African Americans and whites had a similar distribution of IL28B genotypes (P = 0.5). The IL28B CC genotype was overrepresented (P = 0.015) in patients infected with HCV genotype-3 compared with genotype-1. In both genotype-1 and genotype-3, the first-phase viral decline and the average pegylated interferon-alpha-2a effectiveness during the first week of therapy were larger (trend P <= 0.12) in genotype-CC compared with genotypes-TC/TT. In genotype-1 patients, the second slower phase of viral decline (days 2-29) and infected cells loss rate, [delta], were larger (P = 0.02 and 0.11, respectively) in genotype-CC than in genotypes-TC/TT. These associations were not observed in genotype-3 patients.

RESUMO

Though HCV infection is a serious public health problem, some aspects of its biology are still not well understood, such as its transmission through seminal fluid and sexual transmission. We looked for HCV in the semen of infected patients. Thirteen patients were included. Semen fractions (seminal plasma, leukocytes and spermatozoa) were separated with 45% and 90% Percoll gradients. The HCV-RNA in blood and semen fractions was extracted using the same protocol (AMPLICOR Roche) and was detected using the qualitative Roche Amplicor test and by agarose gel electrophoresis, with ethidium bromide staining. The mean age of the patients was 40.7 years. Risk factors for the acquisition of HCV included injectable and inhaled drug use in six (42.8%), blood transfusion in four (28.6%), and no risk factors in four (28.6%) patients. Genotype 1 was detected in 62% of the patients, followed by genotype 3 in 23% and genotype 2 in 15%. All blood samples were positive, regardless of the technique used for detection. All semen samples identified by Roche Amplicor and analyzed by agarose gel electrophoresis were negative. Among the 52 semen samples (total and fractions) identified by the Roche Amplicor method, 45 (87%) were inhibited. A negative result was recorded for one (1.9%) total semen sample, one (1.9%) leukocyte and four (7.7%) seminal plasma fractions. Only one (1.9%) sample of the spermatozoon fraction was positive. The results obtained suggested false-negative reactions for the semen samples.

RESUMO

Introdução: "Gusher" é um fenômeno raro que consiste em súbita saída de líquido céfalo-raquidiano durante a realização da estapedotomia ou estapedectomia. Objetivo: Relatar um caso de "gusher" durante uma estapedotomia e discutir a correlação com a síndrome congênita ligada ao X. Relato do Caso: Paciente NT, 49 anos de idade, sexo feminino, branca, com história de hipoacusia progressiva unilateral direita há 18 anos com piora nos últimos 02 anos com diagnóstico de otosclerose. Realizado estapedotomia com saída súbita de líquido céfalo-raquidiano após platinotomia, sendo realizado selamento da janela oval com gordura de lóbulo de orelha. Conclusões: Esta complicação deve ser considerada em casos de otosclerose, onde o diagnóstico pré-operatório de hipertensão perilinfática é mais difícil em relação a síndrome congênita ligada ao X.


Introduction: "Gusher" is a rare phenomenon that consists in sudden exit of cerebrospinal fluid during the course of stapedotomy or stapedectomy. Objective: To report a case of "gusher" during a stapedotomy and discuss the correlation with X-linked congenital syndrome. Case Report: Patient NT, 49 years old, Caucasian female with history of right unilateral progressive hearing loss for 18 years with worsening in the last 02 years with a diagnosis of otosclerosis. It was performed stapedotomy with sudden exit of cerebrospinal fluid after platinotomia, being carried out sealing the oval window fat ear lobe. Final Comments: This complication should be considered in cases of otosclerosis, where the preoperative diagnosis of perilymphatic hypertension is more difficult for X-linked congenital syndrome.

RESUMO

A atenção primária vem se consolidando em todo mundo como coordenadora de Redes Integradas de Serviços de Saúde (RISS) e, no Brasil, o modelo que melhor representa esse nível de atenção é a Estratégia de Saúde da Família (ESF). As Doenças Crônicas Não Transmissíveis são, hoje, o grupo de enfermidades mais frequente, principalmente em decorrência do aumento da expectativa de vida da população mundial e, dentre delas, a Diabetes Mellitus (DM) tem se apresentado com uma das mais prevalentes. A ESF tem como uma das suas principais atribuições promover o cuidado aos usuários portadores de DM tipo 2, por ser a atenção primária, mais próxima da casa das pessoas e ter na longitudinalidade um dos pilares importantes para o controle desse quadro. A presente pesquisa, do tipo estudo de caso, teve como objetivo analisar como se dá o acompanhamento dos usuários portadores de DM, que frequentam usualmente o Hiperdia, em uma Unidade de Saúde da Família (USF) de Recife. Utilizou métodos quantitativos e qualitativos. Foi adaptada a ficha de cadastro do Hiperdia, onde foram incluídas informações sobre exame físico, comorbidades e internações e aplicada a 57 usuários portadores de DM. Como resultados, obteve-se que o fluxo definido na USF para acompanhar esses usuários não responde às necessidades das pessoas por contemplarem somente um entrada, não prever classificação de risco e também não ter parâmetros assistenciais para melhor usarem a RISS. O estudo se valeu de quatro indicadores, definidos por cruzamento dos dados, que foram: detecção precoce, tratamento, controle e prevenção de complicações. Em todos os indicadores, foi observado um desempenho inferior ao esperado, das Equipes de Saúde da Família. Também foi observado, durante a coleta de dados, grande dificuldade de preenchimento dos dados que não estavam registrados nos prontuários. Concluiu-se que o processo de acompanhamento dos portadores de DM2 nesta USF precisa ser melhor sistematizado, incorporando a classificação de risco e a garantia de exames e procedimentos protocolizados para que a atenção primária se constitua na coordenadora do cuidado.

RESUMO

Though HCV infection is a serious public health problem, some aspects of its biology are still not well understood, such as its transmission through seminal fluid and sexual transmission. We looked for HCV in the semen of infected patients. Thirteen patients were included. Semen fractions (seminal plasma, leukocytes and spermatozoa) were separated with 45 percent and 90 percent Percoll gradients. The HCV-RNA in blood and semen fractions was extracted using the same protocol (AMPLICOR Roche) and was detected using the qualitative Roche Amplicor test and by agarose gel electrophoresis, with ethidium bromide staining. The mean age of the patients was 40.7 years. Risk factors for the acquisition of HCV included injectable and inhaled drug use in six (42.8 percent), blood transfusion in four (28.6 percent), and no risk factors in four (28.6 percent) patients. Genotype 1 was detected in 62 percent of the patients, followed by genotype 3 in 23 percent and genotype 2 in 15 percent. All blood samples were positive, regardless of the technique used for detection. All semen samples identified by Roche Amplicor and analyzed by agarose gel electrophoresis were negative. Among the 52 semen samples (total and fractions) identified by the Roche Amplicor method, 45 (87 percent) were inhibited. A negative result was recorded for one (1.9 percent) total semen sample, one (1.9 percent) leukocyte and four (7.7 percent) seminal plasma fractions. Only one (1.9 percent) sample of the spermatozoon fraction was positive. The results obtained suggested false-negative reactions for the semen samples.
