Abstract
OBJECTIVES Although the prognosis for patients with renal lupus has improved, a small number still progress to renal failure. Studies from the USA have found it difficult to distinguish whether the higher rate of renal failure in African-Americans is due to genetic or socio-economic factors. Our aim was to identify ethnic and other factors in a UK lupus cohort that contribute to renal failure. METHODS The University College London (UCL) Hospitals lupus cohort of 401 patients (Whites 64%, Blacks 19%), followed since 1978, has 127 patients with renal disease, of whom 21 have gone into renal failure. We determined the characteristics and possible causes of renal failure in this group. Black patients were disproportionately represented in the renal failure group (62% vs 19% for Whites). RESULTS Those in the renal failure group had persistently low C3 compared with the renal disease cohort. A high proportion of patients in the renal failure group were felt to be non-adherent to treatment. CONCLUSIONS Given that health-care for patients in the UK is free at the point of delivery, we postulate that in our cohort genetic factors rather than socio-economic status are likely to be more significant in causing renal failure. However, there may be cultural and other reasons for this, which requires further study.

Abstract
The efficacy and safety of ciclesonide was assessed in this randomized, placebo-controlled study in patients with persistent asthma (randomized n=360) maintained on low to moderate doses of inhaled corticosteroids. Patients were randomized to receive ciclesonide 80 or 320 microg (ex-actuator doses, equivalent to 100 and 400 microg ex-valve, respectively) or placebo once daily in the morning via metered-dose inhaler for 12 weeks. Morning peak expiratory flow was maintained throughout the treatment period in patients treated with ciclesonide and decreased significantly in patients treated with placebo (P=0.0003). Ciclesonide (80 and 320 microg) significantly increased forced expiratory volume in 1s from baseline (0.13 and 0.19 L increases, respectively; P<0.01); improvements were superior versus placebo (P=0.0044 for 80 microg ciclesonide; P<0.0001 for 320 microg ciclesonide). The probability of losing efficacy decreased in a dose-dependent manner (55% for placebo, 38% for ciclesonide 80 microg, 23% for ciclesonide 320 microg). Asthma symptom scores and rescue medication use were unchanged with ciclesonide and significantly worsened with placebo. The incidence of adverse events was comparable in all treatment groups and no cortisol suppression was observed. Therefore, ciclesonide 80 and 320 microg administered once daily was a safe and effective maintenance treatment for patients with persistent asthma.

Abstract
The MELD score has now been implemented in the United States for liver allocation, but it has not been validated in Europe. Its association with posttransplant outcome is unclear. Optimal cutoff values of MELD and Child-Pugh scores to predict death on the liver waiting list were defined in a series of 137 cirrhotic patients listed for liver transplantation. Six-month actuarial survival while on the waiting list was 90% with a Child-Pugh <11 and MELD <17, whereas it decreased progressively to 40% at 6 months after listing for those having a Child-Pugh and MELD score >10 and >16. Analysis of a series of 112 patients (85 chronic liver disease and 27 hepatocellular carcinoma) revealed no change in MELD value at the time of transplantation compared to the score at the time of listing (mean +/- SD: 15.5 +/- 7.7 vs 15 +/- 5.8) with a mean waiting time of 118 days. Using either the optimal cutoff for MELD score (<17 or >16) or seven different strata (3 to 7, 8 to 10, 11 to 13, 14 to 16, 17 to 19, 20 to 22, 23 to 39), whether measured at listing or just before liver transplantation, there was no significant difference (chi(2) 4.97, P = .58) in survival: 82.7% and 63% at 6 and 60 months, overall. Our data confirm that the MELD score with only three parameters is as good as the Child-Pugh score to predict mortality on the Eurotransplant waiting list. The optimal cutoff to assess higher priority for the bad category is >16. There was no negative impact on short- or long-term prognosis of the bad categories of MELD.

Abstract
Infection with the hepatitis C virus (HCV) represents an important public health problem and is a leading cause of chronic hepatitis, cirrhosis and hepatocellular carcinoma. Chronic hepatitis C is a heterogeneous disease. Many patients have mild disease at presentation but not all of them will develop advanced liver disease. However, the identification of these patients with mild hepatitis C who will show progressive disease is difficult and is based on histological criteria and the assessment of co-factors (age, alcohol intake, steatosis). In addition, serum transaminases that are persistently normal on several occasions during 18 months may point to a more benign course. Patients with mild hepatitis C should not be excluded "a priori" from the possibility of being treated, as treatment with pegylated interferon and ribavirin is safe and effective in this group. Overall, the decision to initiate therapy should be individualized and based on the severity of the disease by liver biopsy, the potential of serious side effects, the probability of response and the motivation of the patient.

Abstract
This article discusses the use of virologic assays in the diagnosis and management of hepatitis C virus (HCV) and hepatitis B (HBV) infection. The use of virologic tests has become essential in the management of HCV and HBV infection to diagnose viral infection, guide treatment decisions, and assess the virologic response to antiviral therapy. The continuing development of test systems accompanied by new antiviral drugs and novel therapeutic approaches should lead to an optimization of the treatment of HCV infection. Molecular methods for viral testing have become an integral part of the diagnostic and therapeutic management of infections with hepatitis C virus (HCV) and hepatitis B virus (HBV).

Abstract
Colonoscopy is the current gold standard for the diagnosis and treatment of colorectal neoplasms. Several gastroenterological and/or endoscopical societies recommend screening by colonoscopy in high risk patients for colorectal cancer whilst for average risk patients colonoscopy remains a valid option. In some countries screening colonoscopy is now covered by medical insurance. It is also the final common pathway of all colorectal cancer screening methods. This paper addresses the advantages and also limitations of colonoscopy as the first procedure for colorectal screening and emphasizes the importance of organized training and continuous assessment of competence of gastroenterologists and the necessity to have quality control audits of the endoscopy units.

Abstract
Smoking during pregnancy is a public health problem. Throughout this period, cessation is crucial. Everybody agrees that pregnancy is an appropriate moment to try to quit. Continuing smoking is a major risk for both the pregnant woman and her baby to come. Tobacco contains numerous toxics which easily pass through the placenta. All healthcare teams should be committed to helping pregnant women stop smoking and should train themselves to provide advice and support. The healthcare structures should implement consensual preventive and curative actions. Many diagnostic and curative tools are available for global care of pregnant smoking women. Their partners, whether smokers or not, should play a preponderant role. In addition to psychological support, it is important to note that nicotinic substitutes are indispensable tools for helping dependent pregnant women stop smoking.

Abstract
Screening and prevention of colorectal cancer must be a public health priority. It is the most frequent malignancy in Europe, the second leading cause of cancer death, including Belgium where more than 6000 new cases occur per year. Various screening modalities, from non invasive to invasive are available and currently in use and they are all cost-effective in comparison with no screening. The decision as to which screening test to use should be made by the patient and clinician. Consensus documents prepared by the Belgian scientific community appear in this issue of Acta Gastroenterologica Belgica, summarizing the scientific evidence in favour as well as the limitations of fecal occult blood tests, flexible sigmoidoscopy, videocolonoscopy and virtual colonoscopy.

Abstract
Infection due to hepatitis C virus is currently a major public health problem, worldwide but also in Belgium. Indeed, 200 million people (3% of the world population, 1% of the Belgian population) are infected with, in more than 80% of the cases, an evolution toward chronic infection with the potential development of severe liver disease (chronic hepatitis with fibrosis, cirrhosis, hepatocarcinoma). The general practitioner has a central position in the management of hepatitis C. His role is to prevent the infection, giving advice on the risk factors, to screen high risk groups, to monitor infected patients and to discuss with him the indications and contra-indications for antiviral therapy and to follow the treated patient in close collaboration wit the hepatogastroenterologist to ensure adherence, to manage the side effects and to monitor the non treated patient as well as the non responder.

Abstract
The standard treatment for patients with chronic hepatitis C is a 6-12-month combination therapy with interferon alpha and ribavirin. Induction treatment could result in a faster early decline of the hepatitis C virus (HCV) load and a better response rate. Naive chronically infected HCV patients (n = 454) were randomized into two arms to receive either induction treatment with interferon alpha 2b 5 million units (MU) subcutaneously (s.c.) daily during a period of 8 weeks (arm A); or treatment with interferon alpha 2b 5 MU s.c. three times a week (TIW) for a period of 8 weeks (arm B). After week 8, interferon treatment in both arms was 3 MU s.c. TIW for a total period of 12 months. In both arms, ribavirin (1000-1200 mg orally per day) was added at week 4. Induction treatment resulted in a higher virological response at week 8 of treatment (66%vs 47%; P < 0.01). However, response at the end of treatment and at 6 months follow-up was not different (53%vs 50%, 41%vs 33%). The occurrence of adverse events and the drop-out rate were similar in both arms. Although an early virological response is observed more frequently in the induction treatment, end of treatment response and sustained responses did not differ.

Abstract
Physical dependence is a widely known consequence of morphine intake. Although commonly associated with prolonged or repeated morphine administration, withdrawal symptoms can be elicited even after a single prior morphine exposure. What remains contentious is the extent to which physical dependence following acute and chronic morphine treatment is mediated by common physiological substrates and, accordingly, represent distinct syndromes. The genetic relationship between acute and chronic morphine dependence was thus presently studied by comparing mice of 11 inbred strains (129P3, A, AKR, BALB/c, C3H/He, C57BL/6, CBA, DBA/2, LP, SJL, and SWR) for naloxone-precipitated withdrawal jumping responses using three subcutaneous morphine administration paradigms: acute (single injection) or chronic (three daily morphine injections for 4 days) injection, or chronic infusion (7 days via implanted osmotic minipumps). Although there were differences in the magnitude of withdrawal jumping between the three different morphine administration paradigms, large and significant strain differences were observed for each. In addition, the same strains were unusually sensitive or, conversely, altogether refractory to withdrawal jumping across all morphine treatment conditions. Overall, strain jumping means between acute and chronic dependence paradigms displayed a high degree of genetic correlation (r=0.87-0.95). The significant correlation between chronic morphine injection and continuous morphine infusion discounts the possible confounding effect of contextual learning and spontaneous withdrawal between chronic injections on the assessment of naloxone-precipitated withdrawal. Substantial heritability was also observed for acute and both paradigms of chronic dependence, with estimates ranging from h(2)=0.53 to 0.70. The present demonstration of a strong genetic correlation between physical dependence to morphine following acute and chronic treatment implies that genes associated with variable sensitivity in the two traits are the same, and is suggestive of shared physiological substrates. The data also demonstrate that the differential genetic liability to morphine physical dependence begins with, and is predicted by, the first morphine exposure.

Abstract
Chronic hepatitis C infection affects approximately 3% of the world population and is responsible for a large proportion of patients with cirrhosis, end-stage liver diseases, hepatocellular carcinoma and for those who are candidates for liver transplantation or die of liver-related complications. The health care burden of this infection, whose epidemic peaked in the 1980s, is expected to significantly increase in the next 15 years in the absence of an organized national strategy. On the other hand, hepatitis C infection can be easily diagnosed with third generation enzyme immunoassay and indications for molecular biology-based assay are well defined. Composite scores and non-invasive markers of fibrosis may in the future replace liver biopsy which is still recommended in the presence of chronically elevated transaminases and indications for antiviral treatment.

Abstract
OBJECTIVE Do patients with pain accounted for by psychological factors (P) differ in their self-concept and personality disorders from patients with major depression (D) and healthy controls (C)? METHOD Thirty hospitalized P-patients (DSM-IV, 307.80) and 30 hospitalized D-Patients (DSM-III-R) were given the Beck Depression Inventory on admission (BDI-1) and at discharge (BDI-2). Together with BDI-2, patients filled out the Personality Disorder Questionnaire for DSM-III-R (PDQR) and the Frankfurt Self-Concept Scales (FSKN). Thirty-two healthy comparisons (C) completed the same questionnaires. RESULTS BDI-2 showed no significant differences between groups P and D, a prerequisite for the comparison of psychological traits. PDQR differed in the three groups. D showed more dependent, obsessive-compulsive, and histrionic personality features than group P. The three groups differed in FSKN total score and all 10 subscales (C (healthiest self-concept) > P > D). Groups P and D were different (P > D) in total score and subscales: performance, problem coping, confidence in behavior and decision taking, and self-esteem. Ten P-patients with pathological BDI-2 (P(D)) had significantly more disturbed PDQR and FSKN scores than the non-depressed (P(ND)), and closely resembled the D-patients. CONCLUSIONS Personality disorders and self-concept are not homogenous in female patients with P. Subgroup P(ND) differs from patients with depression (fewer personality disorders, better self-concept), whereas subgroup P(D) closely resembles them.

Abstract
The cause of an acute diarrhea is often infectious and a lot of pathogens are implicated: bacteria, parasites and viruses. The clinical approach required several steps and induce different advices such as avoiding stool cultures in the absence of fecal leucocytes, supportive therapy with rehydration, diverse empirical and urgent antibiotherapies. The increasing incidence of antimicrobial resistance of enteropathogens argues against the overconsumption of antibiotics.

Abstract
Covalent conjugates consisting of streptavidin and a 24-mer single-stranded DNA oligonucleotide have been oligomerized by cross-linking with a 5',5'-bis-biotinylated 169-base-pair double-stranded DNA (dsDNA) fragment. The oligomeric conjugates formed have been analyzed by nondenaturing gel electrophoresis and scanning-force microscopy (SFM). The comparison of analogous oligomers, prepared from native STV and the bis-biotinylated dsDNA fragment, revealed that the covalent STV-oligonucleotide hybrid conjugates self-assemble to generate oligomeric aggregates of significant smaller size, containing on average only about 2.5 times less dsDNA fragments per aggregate. Likely, this is a consequence of electrostatic or steric repulsion between the dsDNA and the single-stranded oligomer covalently attached to the hybrid, as indicated from control experiments. Nevertheless, the single-stranded oligonucleotide moiety within the oligomeric conjugates can be used as a selective molecular handle for further functionalization and manipulation. For instance, it was used for specific DNA-directed immobilization at a surface, previously functionalized with complementary capture oligonucleotides. Moreover, we demonstrate that macromolecules, such as STV and antibody molecules, which are tagged with the complementary oligonucleotide, specifically bind to the supramolecular DNA-STV oligomeric conjugates. This leads to a novel class of functional DNA-protein conjugates, suitable, for instance, as reagents in immuno-PCR or as building blocks in molecular nanotechnology.
