Current therapies for chronic hepatitis C virus (HCV) in HIV co-infected patients have a low success rate and are poorly tolerated. We have evaluated the efficacy and safety of interferon alfa-2b ...(IFN) + ribavirin (RBV) versus pegylated interferon alfa-2b (PEG-INF) + RBV.
Randomized, single-centre, open-label clinical trial including patients with: detectable HCV-RNA, alanine aminotransferase > 1.5-fold upper limit of normal, abnormal liver histology, CD4 cell count > 250 x 10/l and HIV RNA < 10 000 copies/ml. Patients were assigned to INF (3 x 10 units three times/week) or PEG-IFN (100-150 microg/week) plus RBV (800-1200 mg/day). Duration of treatment was 48 weeks (only 24 weeks for HCV genotypes 2 or 3 and baseline HCV RNA < 800 000 IU/ml). The primary endpoint was a sustained virological response (SVR).
Ninety-five patients were randomized (43 INF + RBV, 52 PEG-INF + RBV), 68% males, 82% injecting drug users; 63% genotypes 1 or 4 and 36% genotypes 2 or 3; 62% fibrosis index grade >/=2 and 30% bridging fibrosis/cirrhosis. SVR was significantly higher in the PEG-INF + RBV arm, 44% versus 21% (intent to treat; P = 0.017). Among patients with genotypes 1 or 4, SVR were 38% versus 7% (P = 0.007) and 53% versus 47% (P = 0.730) for genotypes 2 or 3. CD4 cell count but not its percentage dropped in both arms and HIV RNA viral load did not change from baseline. Side effects were very frequent in both arms leading to treatment discontinuation in 14 patients without statistical differences between arms (P = 0.565).
PEG-INF + RBV was significantly more effective than INF + RBV for the treatment of chronic hepatitis C in HIV co-infected patients, mainly of genotype 1 or 4.
Virtual communities of practice (vCoPs) facilitate online learning via the exchange of experiences and knowledge between interested participants. Compared to other communities, vCoPs need to overcome ...technological structures and specific barriers. Our objective was to pilot the acceptability and feasibility of a vCoP aimed at improving the attitudes of primary care professionals to the empowerment of patients with chronic conditions.
We used a qualitative approach based on 2 focus groups: one composed of 6 general practitioners and the other of 6 practice nurses. Discussion guidelines on the topics to be investigated were provided to the moderator. Sessions were audio-recorded and transcribed verbatim. Thematic analysis was performed using the ATLAS-ti software.
The available operating systems and browsers and the lack of suitable spaces and time were reported as the main difficulties with the vCoP. The vCoP was perceived to be a flexible learning mode that provided up-to-date resources applicable to routine practice and offered a space for the exchange of experiences and approaches.
The results from this pilot study show that the vCoP was considered useful for learning how to empower patients. However, while vCoPs have the potential to facilitate learning and as shown create professional awareness regarding patient empowerment, attention needs to be paid to technological and access issues and the time demands on professionals. We collected relevant inputs to improve the features, content and educational methods to be included in further vCoP implementation.

Pancreas graft thrombosis is the most common cause of technical graft failure, with an incidence of up to 20% is some series. In most instances, vascular thrombosis of the graft will require ...immediate removal to avoid further abdominal complications. We present a total of four cases of complete venous thrombosis with preservation of function that were managed conservatively, resulting in long-term graft function.
Retrospective analysis of our case series over 10 years was carried out, obtaining patients with complete graft thrombosis by Doppler ultrasound. We included in the study only those patients who remained asymptomatic with preserved graft function. The clinical status of the patients, radiological findings, and therapeutic approach are evaluated. Patient and graft outcomes are analyzed.
Retrospective evaluation of 227 transplants, a total of four patients were found to have complete thrombosis of the graft, remaining asymptomatic and preserving function without complications. Graft thrombosis was found on routine Doppler ultrasound evaluation of the transplanted organs at a median time of 19 days (range, 11-28 days), angiographic confirmation was obtained in all cases. The clinical condition and the presence of collateral flow allowed for conservative treatment. Median hospital stay was 29 days (range, 16-38 days), with a median follow-up of 106 months (range, 24-110 months), all patients are alive with a functioning graft.
In rare instances with complete thrombosis of the pancreas transplant in absence of clinical manifestations, the grafts can be closely monitored and treated with systemic anticoagulation, allowing long-term patient and graft survival.
