Hepcidin-to-ferritin ratio: A potential novel index to predict iron overload-liver fibrosis in ß-thalassemia major.

OBJECTIVES: We aimed to determine a threshold cutoff for hepcidin, ferritin, and the hepcidin-to-ferritin ratio in the diagnosis of liver fibrosis caused by iron overload in chronic hepatitis C virus (HCV)-free ß-thalassemia major patients . METHODS: This 1:1-matched case-control study included 102 individuals (3-30 yr.); 51 ß-thalassemia major patients with iron overload , and 51 apparently healthy individuals. RESULTS: The highest areas under the receiver operating characteristic curves (AUC-ROCs) for the diagnosis of patients vs. controls had overlapping 95% confidence intervals (CIs): serum hepcidin (0.758; 0.64-0.87; P Ë‚ 0.001), serum ferritin (1.000; 1.00-1.00; P˂0.001), and the hepcidin/ferritin ratio (1.000; 1.00-1.00; P˂0.001). For differentiation of patients with liver fibrosis stages of F0-F1 vs. F2-F4 and F0-F1 vs. F3-F4, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) with P-values˂0.001 were the only statistically significant parameters, while the AUC-ROCs of the hepcidin/ferritin ratio (0.631, P=0.188 and 0.684, P=0.098) exhibited 90% and 89.5% sensitivity, respectively, in staging liver fibrosis. CONCLUSION: Our results showed that the hepcidin/ferritin ratio is as effective as the APRI and maybe a better predictor for the diagnosis of liver fibrosis and discriminating its stages, with excellent sensitivity and specificity compared to its components.

Development and evaluation of microbial degradation dependent compression coated secnidazole tablets for colonic delivery.

The present paper describes development of a polysaccharide based compression coated tablets of secnidazole for colon delivery. Core tablet containing secnidazole was compression coated with various proportions of guar gum, xanthan gum and chitosan, either alone or in combinations. Drug release studies were performed in simulated gastric fluid (SGF) for 2 h followed by simulated intestinal fluid (SIF, pH 7.4) up to 24 h. Secnidazole release from the prepared formulations was dependent on the type and concentration of polymer used in the formulation. Tablets coating containing either guar gum or xanthan gum showed ~30-40% drug release in 8 h. Further, in vitro dissolution studies of selected formulations performed in the dissolution media with rat caecal contents showed 54.48±0.24 - 60.42±0.16% of drug release. Formulations with single polymer in coating layer were unsuitable for targeting secnidazole release to colon region. Combination of chitosan with guar gum or xanthan gum exhibited control over secnidazole release.

Examining the effectiveness of a peer-led education programme for Type 2 diabetes and cardiovascular disease in a Bangladeshi population.

AIMS: The aim of this study was to assess an adapted version of the X-PERT Programme for Type 2 diabetes within a Bangladeshi population. METHODS: Bangladeshi adults, living in the UK, with Type 2 diabetes participated in a diabetes educational session based on an adapted version of the X-PERT Programme. Participants attended a session, led by a trained peer educator and carried out in Sylheti. All participants who registered on the course were telephoned or visited in person the day before the course as a reminder. RESULTS: Registration to attend the course was excellent. However, actual attendance rates were 58% (42/72) out of those registered. Once participants attended, overall they enjoyed attending the sessions and felt they benefited as they understood more about how to better self-manage their condition. Those aspects of the sessions that were most enjoyed were group discussions and interactive posters to explain diabetes. Participants requested a home-based exercise guide, which was developed by the research team. The study was underpowered to show behaviour change, but did demonstrate a trend to improvement in self-care activities. All participants reported recommending the course to others. CONCLUSIONS: There was an excellent response in terms of registration for the course. However, the time to attend the course appeared to be a barrier to participants. Nevertheless, for those attending the course, responses were very positive. The amended X-PERT Programme could be used as a component of a package to improve outcome and self-management for people with diabetes in the Bangladeshi community.

Significant influence of the primary liver disease on the outcomes of hepatic retransplantation.

BACKGROUND: There are many indications for hepatic retransplantation. AIM: To identify factors influencing retransplantation needs and outcomes. PATIENTS AND METHODS: Retransplantation records from January 1993 to March 2005 were analysed. Patient and disease characteristics and survival outcomes for retransplantation were compared between various groups. RESULTS: Totally, 286 primary and 42 hepatic retransplantations were performed. Retransplantation indications included primary sclerosing cholangitis (PSC), primary biliary cirrhosis, chronic hepatitis C (HCV), chronic active hepatitis (CAH), and alcohol-related disease. Mean follow-up post-retransplantation was 31 +/- 9 months. Actuarial patient survival at 3 months, 1 year, 3 years, 5 years, and at the end of study was 71.4, 69, 59.5, 54.7, and 50%, respectively. Early and late retransplantation had 1-year survival of 73 and 68.5%, respectively. Retransplantation need was significantly higher for PSC, HCV, and CAH. CONCLUSIONS: Hepatic retransplantation remains a successful salvage option for transplant complications; however, its need is significantly influenced by the primary liver disease.

Intervention, recruitment and evaluation challenges in the Bangladeshi community: experience from a peer lead educational course.

BACKGROUND: The incidence of Type 2 diabetes is increasing worldwide and diabetes is four times more common among ethnic minority groups than among the general Caucasian population. This study reflects on the specific issues of engaging people and evaluating interventions through written questionnaires within older ethnic minority groups. METHODS: The original protocol set out to evaluate an adapted version of the X-PERT patient program http://www.xpert-diabetes.org.uk/ using questionnaires and interviews. RESULTS: Questionnaires, even verbally completed, were unsuccessful and difficult to administer as participants found the questionnaire structure and design difficult to follow and did not perceive any benefit to completing the questionnaires. The benefits of attending the course were also poorly understood by participants and in many cases people participated in coming to the course as a favour to the researcher. Engaging participants required word of mouth and the involvement of active members of the community. CONCLUSION: Peer led courses and their evaluation in older ethnic minority communities needs a very different approach for that in younger Caucasian patients. A structured approached to evaluation (favoured by western educational system) is inappropriate. Engaging participants is difficult and the employment of local well known people is essential.

Clinical studies in persistent diarrhea: dietary management with green banana or pectin in Bangladeshi children.

BACKGROUND & AIMS: Because of the beneficial intestinal effects of dietary fibers, we have evaluated the therapeutic effects of green banana or pectin in children with persistent diarrhea. METHODS: In a double-blind trial, 62 boys, age 5-12 months, were randomly given a rice-based diet containing either 250 g/L of cooked green banana (n = 22) or 4 g/kg pectin (n = 19) or the rice-diet alone (control, n = 21), providing 54 kcal/dL daily for 7 days. Stool weight and consistency, frequency of vomiting and purging, and duration of illness were measured. RESULTS: Most children (60%) had no pathogens isolated from stools, 17% had rotavirus, 5% Vibrio cholerae, 4% Salmonella group B, and 11% had enterotoxigenic Escherichia coli infections. By day 3 posttreatment, significantly (P < 0.001) more children recovered from diarrhea receiving pectin or banana than controls (59%, 55%, and 15%, respectively). By day 4, these proportions correspondingly increased to 82%, 78%, and 23%, respectively, the study diet groups being significantly (P < 0.001) different than controls. Green banana and pectin significantly (P < 0.05) reduced amounts of stool, oral rehydration solution, intravenous fluid, and numbers of vomiting, and diarrheal duration. CONCLUSIONS: Green banana and pectin are useful in the dietary management of persistent diarrhea in hospitalized children and may also be useful to treat children at home.

Necrosectomy followed by closed cavity lavage for necrotising pancreatitis--report of three cases.

Necrotizing Pancreatitis is a life threatening condition involving pancreas, peripancreatic and retroperitoneal tissues. It's serious regional and systemic involvement causes multiple organ or system failure. Planned and carefully performed necresectomy followed by closed cavity lavage can significantly reduce the mortality and morbidity of this catastrophic condition. Meticulous preoperative resuscitation, preparation and operative necrosectomy followed by continuos irrigation in the postoperative period were done in three consecutive patients. The operative procedure including postoperative management and follow up is reported and analyzed.
