basiliximab and lymphopenia

Immunosuppressive therapy can decrease rejection episodes and increase the risk of severe and fatal infections in heart transplantation (HT) recipients. Immunosuppressive therapy can also decrease the absolute lymphocyte count (ALC), but the relationship between early post-transplant ALC and early cytomegalovirus (CMV) infection is largely unknown, especially in HT. We retrospectively analyzed 58 HT recipients who tested positive for CMV IgG antibody and received basiliximab induction therapy. We collected preoperative and 2-month postoperative data on ALC and CMV load...

Tumor necrosis factor (TNF) is a proinflammatory cytokine involved in a wide range of important physiologic processes and has a pathologic role in some diseases. TNF antagonists (infliximab, adalimumab, etanercept) are effective in treating inflammatory conditions. Antilymphocyte biological agents (rituximab, alemtuzumab), integrin antagonists (natalizumab, etrolizumab and vedolizumab), interleukin (IL)-17A blockers (secukinumab, ixekizumab) and IL-2 antagonists (daclizumab, basiliximab) are widely used after transplantation and for gastroenterological, rheumatological, dermatological, neurological and hematological disorders...

Introduction: The cellular events that contribute to generation of donor-specific anti-HLA antibodies (DSA) post-kidney transplantation (KTx) are not well understood. Characterization of such mechanisms could allow tailoring of immunosuppression to benefit sensitized patients. Methods: We prospectively monitored circulating T follicular helper (cTFH ) cells in KTx recipients who received T-cell depleting (thymoglobulin, n  = 54) or T-cell nondepleting (basiliximab, n  = 20) induction therapy from pre-KTx to 1 year post-KTx and assessed their phenotypic changes due to induction and DSA occurrence, in addition to healthy controls ( n  = 13), for a total of 307 blood samples...

Cytomegalovirus (CMV) is one of the most frequently encountered opportunistic viral pathogens in kidney transplant recipients. In this study, we retrospectively reviewed all living related and unrelated kidney transplant recipients on regular follow-up from January 2006 to June 2015, who were suspected to have CMV clinically and confirmed by DNA polymerase chain reaction (PCR). CMV PCR was detected in 102 kidney transplant recipients. The median time of detection after kidney transplant was 21 months, ranging from 15 days to 84 months...

An expanding list of immunomodulatory or immunosuppressive monoclonal antibodies (mAbs) and biologic therapeutics is currently entering clinical practice, particularly in the areas of oncology, transplantation and autoimmune disorders. These agents are directed against molecules or cells involved in inflammation and immunity and may therefore be associated with serious and opportunistic infections. The purpose of this review was to critically analyse the literature on invasive fungal infections (IFIs) occurring in association with mAbs and fusion proteins other than tumour necrosis alpha (TNF-α) inhibitors, including therapeutics modulating T-cell-mediated pathologies (muromonab, abatacept, belatacept, ipilimumab, basiliximab, daclizumab), inducing lymphopenia (alemtuzumab), depleting CD20+ B cells (rituximab) and interfering with various targets (anakinra, natalizumab, blodalumab, ixekizumab and others) with a focus on children, and to provide a framework of evaluating the risk for IFIs in this population...

To better understand the kinetics of the delayed reconstitution of peripheral CD4+ T-cells after depletion with a single administration of alemtuzumab (AL) for renal transplantation, we evaluated in these patients the percentage and absolute number of recent thymic emigrants (RTEs) CD4+ T cells, together with naive and memory subsets, defined by the analysis of CD31, CD45RA and CCR7 expression, and compared with patients treated with a nondepleting protocol based on basiliximab, and with healthy controls. In AL-treated patients, the number of circulating CD4+ T cells was greatly reduced 1 year after the infusion (P < 0...

Thymoglobulin has a proven safety and efficacy profile both as treatment of acute rejection and as induction therapy in organ transplantation. The most common adverse events associated with Thymoglobulin are cytokine release syndrome, thrombocytopenia, and lymphopenia. Results of early studies showed an increased rate of cytomegalovirus disease associated with Thymoglobulin treatment, but recent studies indicate that routine administration of modern antiviral prophylaxis can reduce this risk. More research comparing Thymoglobulin with basiliximab will help individualize regimens by matching the choice of induction agent with the risk profile of each transplant recipient...

Reduction of delayed graft function (DGF) is critical to the success of renal transplantation. We report graft outcomes with antithymocyte globulin (ATG) induction compared with using interleukin-2 receptor antagonist basiliximab (IL-2RA). Twelve pediatric patients received a pediatric deceased donor kidney. We treated them with ATG (group A, ATG; n = 6) or IL-2RA (group B, n = 6). DGF was observed in 0 cases (group A) and in 6 cases (group B), which showed a mean of 7 +/- 3 days (P < .001). In group A, lymphopenia occurred routinely resolving after 3-6 months, none with serious infection...
