Impact of donor and recipient IL28B rs12979860 genotypes on hepatitis C virus liver graft reinfection.

BACKGROUND & AIMS: Recent studies have described a major impact of genetic variations near the IL28B gene on the natural course and outcome of antiviral therapy in chronic hepatitis C. We therefore, aimed to explore the impact of donor and recipient genotypes of these polymorphisms on hepatitis C virus (HCV) liver graft reinfection. METHODS: Donor and recipient genotypes of IL28B rs12979860C>T single nucleotide polymorphism were determined in 91 patients with HCV liver graft reinfection, 47 of whom were treated with pegylated interferon-α (PEG-IFN-α) and ribavirin. IL28B genetic polymorphisms were correlated with the natural course and treatment outcome of recurrent hepatitis C. RESULTS: Patients requiring liver transplantation due to end-stage chronic hepatitis C appeared to be selected toward the adverse genotypes rs12979860 CT/TT compared to non-transplanted HCV-infected patients (p=0.046). Patients with the donor genotype rs12979860 CC had higher peak ALT and HCV RNA serum concentrations than those with CT/TT (p=0.04 and 0.06, respectively). No association was observed between ALT/HCV RNA serum concentrations and recipient genotypes (p>0.3). More important, donor IL28B rs12979860 CC vs. CT/TT genotypes were associated with rapid, complete early, and sustained virologic response (RVR, cEVR, SVR) to treatment with PEG-IFN-α and ribavirin (p=0.003, 0.0012, 0.008, respectively), but weaker associations of recipient genotypes with RVR, cEVR, and SVR were observed as well (p=0.0046, 0.115, 0.118, respectively). CONCLUSIONS: We provide evidence for a dominant, but not exclusive impact of the donor rather than the recipient IL28B genetic background on the natural course and treatment outcome of HCV liver graft reinfection.

Arabidopsis jasmonate signaling pathway.

Jasmonates control defense gene expression and male fertility in the model plant Arabidopsis thaliana. In both cases, the involvement of the jasmonate pathway is complex, involving large-scale transcriptional reprogramming. Additionally, jasmonate signaling is hard-wired into the auxin, ethylene, and salicylate signal networks, all of which are under intense investigation in Arabidopsis. In male fertility, jasmonic acid (JA) is the essential signal intervening both at the level of anther elongation and in pollen dehiscense. A number of genes potentially involved in jasmonate-dependent anther elongation have recently been discovered. In the case of defense, at least two jasmonates, JA and its precursor 12-oxo-phytodienoic acid (OPDA), are necessary for the fine-tuning of defense gene expression in response to various microbial pathogens and arthropod herbivores. However, only OPDA is required for full resistance to some insects and fungi. Other jasmonates probably affect yet more physiological responses. A series of breakthroughs have identified the SKP/CULLIN/F-BOX (SCF), CORONATINE INSENSITIVE (COI1) complex, acting together with the CONSTITUTIVE PHOTOMORPHOGENIC 9 (COP9) signalosome, as central regulatory components of jasmonate signaling in Arabidopsis. The studies, mostly involving mutational approaches, have paved the way for suppressor screens that are expected to further extend our knowledge of jasmonate signaling. When these and other new mutants affecting jasmonate signaling are characterized, new nodes will be added to the Arabidopsis Jasmonate Signaling Pathway Connections Map, and the lists of target genes regulated by jasmonates in Arabidopsis will be expanded.

Diagnostic and prognostic value of antibodies against chimeric fibrin/filaggrin citrullinated synthetic peptides in rheumatoid arthritis

Introduction: Evidence suggests that citrullinated fibrin(ogen) may be a potential in vivo target of anticitrullinated protein/peptide antibodies (ACPA) in rheumatoid arthritis (RA). We compared the diagnostic yield of three enzyme-linked immunosorbent assay (ELISA) tests by using chimeric fibrin/filaggrin citrullinated synthetic peptides (CFFCP1, CFFCP2, CFFCP3) with a commercial CCP2-based test in RA and analyzed their prognostic values in early RA. Methods: Samples from 307 blood donors and patients with RA (322), psoriatic arthritis (133), systemic lupus erythematosus (119), and hepatitis C infection (84) were assayed by using CFFCP- and CCP2-based tests. Autoantibodies also were analyzed at baseline and during a 2-year follow-up in 98 early RA patients to determine their prognostic value. Results: With cutoffs giving 98% specificity for RA versus blood donors, the sensitivity was 72.1% for CFFCP1, 78.0% for CFFCP2, 71.4% for CFFCP3, and 73.9% for CCP2, with positive predictive values greater than 97% in all cases. CFFCP sensitivity in RA increased to 80.4% without losing specificity when positivity was considered as any positive anti-CFFCP status. Specificity of the three CFFCP tests versus other rheumatic populations was high (> 90%) and similar to those for the CCP2. In early RA, CFFCP1 best identified patients with a poor radiographic outcome. Radiographic progression was faster in the small subgroup of CCP2-negative and CFFCP1-positive patients than in those negative for both autoantibodies. CFFCP antibodies decreased after 1 year, but without any correlation with changes in disease activity. Conclusions: CFFCP-based assays are highly sensitive and specific for RA. Early RA patients with anti-CFFCP1 antibodies, including CCP2-negative patients, show greater radiographic progression.

Profile, cost and pattern of prescriptions for polymedicated patients in Catalonia (Spain).

OBJECTIVES: Polypharmacy is one of the main management issues in public health policies because of its financial impact and the increasing number of people involved. The polymedicated population according to their demographic and therapeutic profile and the cost for the public healthcare system were characterised. DESIGN: Cross-sectional study. SETTING: Primary healthcare in Barcelona Health Region, Catalonia, Spain (5 105 551 inhabitants registered). PARTICIPANTS: All insured polymedicated patients. Polymedicated patients were those with a consumption of ≥16 drugs/month. MAIN OUTCOMES MEASURES: The study variables were related to age, gender and medication intake obtained from the 2008 census and records of prescriptions dispensed in pharmacies and charged to the public health system. RESULTS: There were 36 880 polymedicated patients (women: 64.2%; average age: 74.5±10.9 years). The total number of prescriptions billed in 2008 was 2 266 830 (2 272 920 total package units). The most polymedicated group (up to 40% of the total prescriptions) was patients between 75 and 84 years old. The average number of prescriptions billed monthly per patient was 32±2, with an average cost of 452.7±27.5. The total cost of those prescriptions corresponded to 2% of the drug expenditure in Catalonia. The groups N, C, A, R and M represented 71.4% of the total number of drug package units dispensed to polymedicated patients. Great variability was found between the medication profiles of men and women, and between age groups; greater discrepancies were found in paediatric patients (5-14 years) and the elderly (≥65 years). CONCLUSIONS: This study provides essential information to take steps towards rational drug use and a structured approach in the polymedicated population in primary healthcare.

Menschliche Bedürfnisse und Parteipolitik

Im Jahre 1978 lag die Selbstmordrate in der Bundesrepublik Deutschland einschließlich Berlin-West mit 22,2 auf 100000 Einwohner um 1,7 höher als zehn Jahre zuvor. Im gleichen Zeitraum etwa (1970-1979) stieg die jährliche Anzahl der Drogentoten von knapp 30 auf über 600. Eigentumsdelikte (Diebstahl, Betrug, Unterschlagung) und schwere Körperverletzungen nahmen von 1969 bis 1979 jeweils um mehr als 60 Prozent zu. Der Zigarettenkonsum erhöhte sich zwischen 1965 und 1979 um mehr als ein Viertel, die Zahl der behandlungsbe-dürftigen Alkoholkranken (ab 1968) um 450 Prozent. Der Verbrauch von Psychopharmaka hat sich währenddessen ungefähr verdoppelt.

Commentary : beyond vague causal effect estimation of obesity on health outcomes

In the current issue of epidemiology, Danaei and colleagues elegantly estimated both the direct effect and the indirect effect-that is, the effect mediated by blood pressure, cholesterol, glucose, fibrinogen, and high-sensitivity C-reactive protein-of body mass index (BMI) on the risk of coronary heart disease (CHD). they analyzed data from 9 cohort studies including 58,322 patients and 9459 CHD events, with baseline measurements between 1954 and 2001. Using sophisticated and cutting-edge methods for direct and indirect effect estimations, the authors estimated that half of the risk of overweight and obesity would be mediated by blood pressure, cholesterol, and glucose. Few additional percentage points of the risk would be mediated by fibrinogen and hs-CRP. How should we understand these estimates? Can we say that if obese persons reduce their body weight and reach a normal body weight, their excess risk of CHD would be reduced by half through an improvement in these mediators and by half through the reduction in BmI itself? Is that also true if these individuals are prevented from becoming obese in the first place? Can we also conclude that if these mediators are well controlled in obese individuals through other means than a body weight reduction, their excess risk of CHD would be reduced by half? Let us confront these estimates with observations from studies evaluating 2 interventions to reduce body weight, that is, bariatric surgery in patients with severe obesity and intensive lifestyle intervention in overweight patients with diabetes

Zyoptix-LASIK : sarveiskalvon taittovirhekirurgian aiheuttamat komplikaatiot myopian korjaamisessa

Opinnäytetyön tarkoituksena oli tutkia sarveiskalvon taittovirhekirurgian aiheuttamia komplikaatioita ja niiden ilmenemiseen vaikuttavia tekijöitä myopian korjaamisessa. Tarkastelun kohteena olivat myös leikkaustuloksen pysyvyys, regressio ja ylikorjaukset kuukauden, kuuden kuukauden ja vuoden kuluttua Zyoptix®LASIK-leikkauksesta. Tutkimus oli laadultaan kvantitatiivinen ja se toteutettiin yhteistyössä Eiran sairaalan kanssa. Sain käyttööni Eiran sairaalan potilaskortiston, josta siirsin tarvittavat tiedot Datagraph-ohjelmaan. Tutkimusjoukko muodostui 322 myooppisesta silmästä, jotka silmäkirurgi Harri Koskela leikkasi Eiran sairaalassa tammi-kesäkuussa vuonna 2005 Zyoptix®LASIK-leikkausmenetelmällä. Tutkimustulosten mukaan komplikaatioita esiintyi vain 1,2 %:lla koko tutkimusjoukosta. Myopian määrällä ei tutkimuksen mukaan ollut tilastollisesti merkitsevää vaikutusta komplikaatioiden ilmenemiseen eikä leikkaustuloksen pysyvyyteen. Esiintyneitä komplikaatioita olivat debris, läpän dislokaatio, haze ja epiteelin kasvu. Eniten komplikaatioita esiintyi erittäin suuriasteisessa myopiassa, jolloin myös sarveiskalvon paksuus ja sarveiskalvolle tehtävän läpän paksuus olivat pienempiä verrattuna vähäisempään myopian määrään. Ablaatiosyvyys korreloi negatiivisesti taittovirheen määrän kanssa, jolloin myopian määrän kasvaessa ablaatiosyvyys kasvoi tilastollisesti erittäin merkitsevästi. Leikkaustulos oli pysyvä kuukauden ja kuuden kuukauden kuluttua Zyoptix®LASIK-leikkauksesta riippumatta myopian määrästä. Vuoden kuluttua leikkauksesta suurilla myoopeilla tapahtui lievää regressiota. Tulevaisuudessa taittovirhekirurgia on tärkeä taittovirheen korjausmuoto silmälasien ja piilolinssien ohella. Opinnäytetyö tukee ammattiosaamistani toimiessani näönhuollon asiantuntijana. Tutkimuksen suuren otoskoon vuoksi opinnäytetyön tulosta voi pitää luotettavana.

Medication exposure during pregnancy: a pilot pharmacovigilance system using health and demographic surveillance platform.

BACKGROUND: There is limited safety information on most drugs used during pregnancy. This is especially true for medication against tropical diseases because pharmacovigilance systems are not much developed in these settings. The aim of the present study was to demonstrate feasibility of using Health and Demographic Surveillance System (HDSS) as a platform to monitor drug safety in pregnancy. METHODS: Pregnant women with gestational age below 20 weeks were recruited from Reproductive and Child Health (RCH) clinics or from monthly house visits carried out for the HDSS. A structured questionnaire was used to interview pregnant women. Participants were followed on monthly basis to record any new drug used as well as pregnancy outcome. RESULTS: 1089 pregnant women were recruited; 994 (91.3%) completed the follow-up until delivery. 98% women reported to have taken at least one medication during pregnancy, mainly those used in antenatal programmes. Other most reported drugs were analgesics (24%), antibiotics (17%), and antimalarial (15%), excluding IPTp. Artemether-lumefantrine (AL) was the most used antimalarial for treating illness by nearly 3/4 compared to other groups of malaria drugs. Overall, antimalarial and antibiotic exposures in pregnancy were not significantly associated with adverse pregnancy outcome. Iron and folic acid supplementation were associated with decreased risk of miscarriage/stillbirth (OR 0.1; 0.08 - 0.3). CONCLUSION: Almost all women were exposed to medication during pregnancy. Exposure to iron and folic acid had a beneficial effect on pregnancy outcome. HDSS proved to be a useful platform to establish a reliable pharmacovigilance system in resource-limited countries. Widening drug safety information is essential to facilitate evidence based risk-benefit decision for treatment during pregnancy, a major challenge with newly marketed medicines.
