However, in the past few years, few cases have come forward in which after treatment with a monoclonal antibody, Alemtuzumab, patients developed sarcoidosis. This antibody targets the pan-lymphocyte CD52 antigen found on both human lymphoid and myeloid cells and is used in the treatment of Relapsing Remitting Multiple Sclerosis, leukemia, etc. Patients, in these cases, after a few years of treatment developed sarcoidosis but fortunately responded well to the treatment, if needed.

He was administered alemtuzumab twice (at the time of initial treatment and relapse) and cyclophosphamide, vincristine, and hydrocortisone chemotherapy. Furthermore, novel therapeutic drugs (venetoclax and tofacitinib) were administered based on previous case reports...Consideration should be given to suspending treatment, adjusting the administration interval, or administering G-CSF if necessary. The treatment interval can be appropriately adjusted, making it a valuable treatment option for refractory T-PLL.

We present a patient diagnosed with T-PLL with MTCP1 rearrangement who was successfully treated with alemtuzumab followed by consolidative allogeneic unrelated donor stem cell transplantation...However, the lymphoma cells were clonally related to those at presentation. Currently, literature on T-PLL-like cases lacking the rearrangement of TCL1A is limited, and the possibility of whether a proportion of such cases could represent PTCL, NOS (with leukemic involvement) needs consideration.

Inhibition of kinases involved in the CD40-signaling cascade revealed that the SRC-kinase inhibitor dasatinib prevented rescue of T-cell function independent of CD40-mediated increased levels of costimulatory and adhesion ligands on CLL cells...These results demonstrate that T cells derived from CLL patients can be reinvigorated by manipulating CLL-T cell interactions. Targeting CD24- and CD52-mediated CLL-T cell interaction could be a promising therapeutic strategy to enhance T-cell function in CLL.

Furthermore, aerobic glycolysis induced by 2-DG inhibited the proliferation of NSCLC cells. In conclusion, CD52 knockdown inhibited aerobic glycolysis and malignant behavior of NSCLC cells through AKT signaling pathway, which may be employed in an alternative therapeutic target for NSCLC.

However, increased infections and relapse resulted in a lack of survival benefit after long-term follow-up. ClinicalTrials.gov identifier: NCT00520130.

This study of ex vivo T-cell depleted SCT's demonstrates that NK cells recover quicker when compared to those receiving unfractionated grafts. These results may have implications for GvHD and the GvL effect which warrants further study.

Abnormal cells in BM and PB became undetectable on microscopy and FCM, and the CNS lesion disappeared on MRI after second-line therapy with alemtuzumab...Allogeneic hematopoietic stem-cell transplantation was performed, and the fusion mRNA has now been undetectable for more than 5 years since transplantation. This is the first report of a T-PLL case with a CLEC16A::IL2 fusion gene.

Analysis of such a gene signature uncovers a specific transcriptional program associated with mPMN-MDSC differentiation and allows us to identify that, in patients with either solid or hematologic tumors and in GDs, CD52, CD84, and prostaglandin E receptor 2 (PTGER2) represent potential mPMN-MDSC-associated markers. Altogether, our findings indicate that mature PMN-MDSCs distinctively undergo specific reprogramming during differentiation and lay the groundwork for selective immunomonitoring, and eventually targeting, of mature PMN-MDSCs.

Approaches to prevent GVHD include pharmacologic strategies such as calcineurin inhibitors (cyclosporine, tacrolimus) combined with methotrexate or mTOR inhibitors (sirolimus), and IMP dehydrogenase inhibitors (mycophenolate mofetil). Increasingly, posttransplant cyclophosphamide is emerging as a promising strategy for GVCHD prevention especially in a setting of reduced intensity conditioning. Other approaches include serotherapy (ATG, Campath) and graft manipulation strategies...Targeted therapies including Bruton's tyrosine kinase inhibition, JAK1/2 inhibition, and ROCK2 inhibitors have improved cGVHD therapy, especially in the steroid refractory setting. Continued improvement in prophylactic strategies for cGVHD, identification of accurate cGVHD treatment endpoints, and access to novel therapeutic agents are expected to improve cGVHD outcomes.

Conditioning was myeloablative busulfan with pharmacokinetic monitoring and fludarabine +/- cyclophosphamide/thiotepa or a reduced intensity melphalan-based regimen with fludarabine. All patients received serotherapy with ATG or alemtuzumab. Post-PSCT immune suppression was none or mycophenolate mofetil (MMF) and/or a calcineurin inhibitor (CNI)... 41 patients with a variety of IEIs were included (Figure 1). At a median follow-up of 2.5 years, OS was 85% (95% CI 75-97%) and EFS 80% (95% CI 69-94%), but was variable by underlying disease (Figure 2). Three patients experienced graft failure (7.3%), two requiring a second transplant and one receiving donor lymphocyte infusion only.
