Abstract
INTRODUCTION Cytomegalovirus (CMV) is the most clinically relevant infectious agent following heart transplantation (HTX). Data on the beneficial effects of prophylactic use of CMV immunoglobulins (CMVIG) are scarce. METHODS In this single-center, retrospective study, we reported patient outcomes following cardiac transplantation using prophylactic CMV treatment, including CMVIG. Distinct clinically relevant outcomes were compared across different CMV risk groups (CMV D-/R-, CMV D-/R+, CMV D+/R+, and CMV D+/R- or CMV high risk group). RESULTS We included 272 heart transplant procedures, performed between 1/1/2009 and 1/11/2020. Sixty-one (22%) procedures belonged to the CMV high risk group, while 96 (35%), 50 (18%), and 65 (24%) were CMV D-/R-, CMV D-/R+, and CMV D+/R+, respectively. Baseline donor and recipient characteristics (sex, age, body mass index, cause of death, indication for HTX), ischemia times and baseline immunosuppressive regimens were similar across the different CMV risk groups, yet fewer patients were bridged with a mechanical circulatory support in the CMV D+/R- group. CMV disease following cardiac transplantation was more common in the CMV D+/R- risk group (n = 40 or 66.7%; p < .001), yet mortality and re-transplantation rates, cardiac allograft vasculopathy (CAV) severity, rejection episodes, and development of donor-specific antibodies (DSA), post-transplant lymphoproliferative diseases (PTLD), and EBV infections were similar across all four CMV risk groups. CONCLUSION High risk CMV D+/R- patients had a similar survival compared to low and intermediate CMV risk groups using a prophylactic strategy combining CMVIG and viral DNA polymerase inhibitors. This may be related to a number of factors unrelated to prophylaxis strategy as two out of three CMV D+/R- recipients developed CMV primary infection after prophylaxis was discontinued.

Abstract
Acute parvovirus B19 (B19V) infection in immunocompromised patients may lead to severe anemia. However, in adult transplant recipients, B19V reactivations without anemia and low-level viremia are common. The impact of B19V in pediatric transplant patients, with high risk of primary infection, is investigated here. In a six-month period, 159 blood samples of 54 pediatric liver transplant recipients were tested for B19V DNA by quantitative real-time PCR. Viremia was correlated with anemia and immunosuppression and compared with rates in adult transplant recipients. B19V DNA was detected in 5/54 patients. Primary B19V infections were observed in four patients prior to and in one patient after transplantation. Rates of viremia were significantly higher in pediatric recipients than in adults. Prolonged virus shedding after primary infection prior to transplantation accounts for most viremic cases. Anemia was significantly more frequent in samples from viremic patients, but remained mild. In 15% of anemic samples, B19V DNA was detected. Therefore, in anemic pediatric transplant recipients, diagnostics for B19V seem reasonable.

Abstract
A growing population of long-term survivors of myeloma is now accumulating the 'late effects' not only of myeloma itself, but also of several lines of treatment given throughout the course of the disease. It is thus important to recognise the cumulative burden of the disease and treatment-related toxicity in both the stable and active phases of myeloma, some of which is unlikely to be detected by routine monitoring. We summarise here the evidence for the key late effects in long-term survivors of myeloma, including physical and psychosocial consequences (in Parts 1 and 2 respectively), and recommend the use of late-effects screening protocols in detection and intervention. The early recognition of late effects and effective management strategies should lead to an improvement in the management of myeloma patients, although evidence in this area is currently limited and further research is warranted.

Abstract
AIM The objective of this systematic review was to characterize the pharmacokinetics and pharmacodynamics of denosumab (XGEVA®), a fully human IgG2 monoclonal antibody which binds to receptor activator of nuclear factor kappa-B ligand (RANKL), for the treatment of skeletal-related events (SREs) in patients with advanced cancer and bone metastases. METHODS A total of 708 patients (116 healthy patients and 592 patients with solid tumours or multiple myeloma and bone metastases) included in seven clinical studies were evaluated for denosumab pharmacokinetics. Denosumab was administered as a single subcutaneous (s.c.) dose or multiple s.c. doses, ranging from 0.1 to 3.0 mg kg(-1) or 30 mg to 180 mg fixed dosing, every 1 or 3 months for up to 45 months. RESULTS Consistent with the results in healthy adults, single s.c. doses of denosumab demonstrated dose-dependent, non-linear pharmacokinetics in advanced cancer patients with bone metastases across a wide dose range (0.1-3.0 mg kg(-1) ). Reductions in levels of the bone turnover marker, uNTx/Cr, were observed within 1 day. The duration of reductions generally increased with dose and dosing frequency. In patients with solid tumours and bone metastases, pharmacokinetics and pharmacodynamic comparisons across tumour types and concomitant cancer therapies (chemotherapies and/or hormone therapies) suggest that neither tumour type nor type of concomitant therapy markedly affects denosumab pharmacokinetics or pharmacodynamics. CONCLUSIONS Denosumab displayed non-linear pharmacokinetics at doses below 60 mg but at higher doses, denosumab exposure increased approximately dose-proportionally in advanced cancer patients with bone metastases. Following a 120 mg, every 4 weeks dosing schedule, similar denosumab pharmacokinetics and pharmacodynamics were observed across tumour types and were independent of concomitant cancer therapies.

Abstract
Hepatitis B re-infection prophylaxis is crucial for graft and recipient survival for transplanted patients and is administered routinely after liver transplantation for hepatitis B. Aim of the current study was the investigation of efficacy, safety and feasibility of home-treatment of a novel human hepatitis B immunoglobulin BT088 (Zutectra) after weekly subcutaneous application in liver-transplanted patients. A total of 23 patients (5 female, 18 male, median age 51 years) were enrolled and switched from monthly IV to weekly SC hepatitis B immunoglobulin administration. During a period of 18 weeks (optional 24 weeks) anti-HBs levels, signs of re-infection, adverse events and feasibility of self-administration were studied. After 8 weeks of training patients showing good compliance and stable antibody titres were allowed to start self-administration at home. All patients maintained a safety level of >100 U/l anti-HBs. No failure was noted, no re-infection occurred. A total of 10 treatment-emergent events were assessed as related to study drug application (injection-site haematoma, headache, abdominal pain, fatigue and haematuria). High numbers of self-administration (287 vs. 122 by staff) demonstrated general feasibility of SC administration. Weekly subcutaneous administration of BT088 (Zutectra - registered trade mark in the EU) is effective, safe and presents an easy-to-apply treatment option for combined hepatitis B virus re-infection prophylaxis in liver transplant patients (Eudra CT Number: 2005-003737-40).

Abstract
Hepatitis B immunoglobulin (HBIG) administration remains an essential component of standard reinfection prophylaxis after liver transplantation for hepatitis B virus-related liver disease. Previous studies have suggested that intramuscular (IM) HBIG administration compared to intravenous (IV) HBIG administration may be cost-effective and dose-saving. To compare antibody against hepatitis B surface antigen (anti-HBs) kinetics after IV HBIG administration versus IM HBIG administration, 24 patients received 2000 IU of HBIG every 6 weeks over a study period of 48 weeks in a crossover design. HBIG was started intravenously in 12 patients (group A) and intramuscularly in 12 patients (group B). After 4 doses, at week 24 HBIG administration was switched from IM to IV and vice versa. Anti-HBs kinetics of 22 patients were evaluated. Mean anti-HBs levels measured 2, 4, and 6 weeks after each HBIG administration did not differ significantly (480 +/- 166, 319 +/- 126, and 221 +/- 106 IU/L after IV administration versus 457 +/- 166, 310 +/- 147, and 218 +/- 112 IU/L after IM administration). Half-lives of anti-HBs decline (IV, 25.5 +/- 6.0 days, versus IM, 24.7 +/- 6.2 days) and area under the curve values from week 2 to 6 (IV, 9.4 +/- 3.6 IU*day/mL, versus IM, 9.0 +/- 3.9 IU*day/mL) also showed no significant difference. Variation of anti-HBs levels after IV HBIG administration versus IM HBIG administration was neither significantly different within patients (intraindividual variance) nor between patients (interindividual variance). However, intraindividual variance was lower than interindividual variance after IV (P < 0.05) and IM (P < 0.05) HBIG administration at every time point (2, 4, and 6 weeks). In conclusion, IV HBIG administration and IM HBIG administration are equally effective with respect to the crucial pharmacokinetic parameters. That is, IM HBIG is not dose-saving; however, it may be cost-effective if the price per unit is lower. Individualized dosing intervals should be further evaluated as a cost-effective alternative to fixed dosing schemes.

Abstract
Oncolytic viruses are being developed as anticancer drugs. They propagate selectively in tumor tissue and destroy it without causing excessive damage to normal non-cancerous tissues. When used as drugs, they must meet stringent criteria for safety and efficacy and be amenable to pharmacological study in human subjects. Specificity for neoplastic tissue is the key to safety, and this goal can be achieved through a variety of ingenious virus-engineering strategies. Antiviral immunity remains a significant barrier to the clinical efficacy of oncolytic viruses but this is being addressed by using novel immune-evasive delivery strategies and immunosuppressive drugs. Noninvasive pharmacokinetic monitoring is facilitated by engineering marker genes into the viral genome. Clinical data on the pharmacokinetics of oncolytic viruses will be the key to accelerating their development and approval as effective anticancer drugs. This review introduces concepts relevant to the use of viruses as anticancer drugs, emphasizing targeting mechanisms as well as safety and efficacy issues that are currently limiting their clinical success.

Abstract
BACKGROUND/AIMS Administration of hepatitis B immunoglobulin (HBIG) initially after liver transplantation of hepatitis B patients is considered important to prevent reinfection reliably. However, dosing schedules differ considerably between centers. We measured HBsAg, anti-HBs and HBV DNA kinetics to create a rational basis for dosing schemes. METHODS Thirteen patients (group A) received 10,000 IU HBIG in the anhepatic phase followed by 10,000 IU daily until HBsAg became negative, whereas five patients (group B) received 20,000 IU followed by 5000 IU every 30 min. RESULTS HBsAg levels at time of transplantation ranged from 0.12 to 12,990 IU/ml. Correlations between initial HBsAg and HBIG required to decrease HBsAg below 1 IU/ml were high in groups A and B (r=0.97, p<0.001; r=1.00, p<0.001), as were correlations between initial HBsAg and HBIG required to raise anti-HBs above 1000 IU/l (r=0.94, p<0.001; r=1.00, p<0.001). In 11 HBV DNA-positive patients, DNA levels became negative in seven, and dropped by 2.5 log10 (mean) in the other four patients during immunoglobulin administration. CONCLUSIONS In conclusion, required HBIG doses to decrease HBsAg and raise anti-HBs are determined by HBsAg levels at time of transplantation, not by HBV DNA levels. Shortened HBIG dosing intervals accelerate HBsAg decrease and anti-HBs increase. HBV DNA decreases rapidly during HBIG administration in most patients.

Abstract
BACKGROUND Post-transplant non-Hodgkin lymphoma is a feared complication of immunosuppressive treatment and is associated with high mortality. Most post-transplant lymphomas develop from the uncontrolled proliferation of Epstein-Barr-virus (EBV)-infected B lymphocytes. No reliable methods for the prevention of EBV infection and lymphoma are available. We aimed to elucidate the effect of prophylactic treatment for cytomegalovirus (CMV) infection on the incidence of post-transplant lymphomas. METHODS In a multicentre retrospective study, we analysed the incidence of post-transplant non-Hodgkin lymphoma in 44 828 recipients of deceased-donor kidney transplants who were reported to the scientific registry of the Collaborative Transplant Study. Patients had received antiviral drugs (aciclovir or ganciclovir) or anti-CMV immunoglobulin to prevent CMV infection according to the transplant centres' protocols, or no CMV prophylaxis. Standardised incidence ratios (SIR) of lymphoma were calculated and compared by chi(2) analyses FINDINGS During the first post-transplantation year, 30 255 patients who did not receive CMV prophylaxis developed lymphomas at SIR 26.4. Lymphoma incidence in 12 470 patients who received antiviral treatment was nearly identical (SIR 24.2, p=0.62) to that in patients who did not receive CMV prophylaxis. However, 2103 patients who received anti-CMV immunoglobulin showed a complete absence of lymphomas in the first after-transplantation year (SIR 0; p=0.012 vs no treatment, p=0.016 vs antivirals). In the subsequent 5 years of follow-up, new cases of lymphoma developed at similar rates in all three groups (p=0.97). INTERPRETATION These findings suggest that prophylactic anti-CMV immunoglobulin prevents the development of early post-transplant non-Hodgkin lymphoma in kidney-graft recipients. Prophylactic treatment with antiviral drugs does not reduce the risk of post-transplant lymphoma.
