Introduction: There is a high prevalence of cytomegalovirus (CMV) seropositivity in developing countries. An apparent risk of CMV reactivation increases following hematopoeitic stem cell transplantation. With effective surveillance and timely treatment using anti-viral therapy, morbidity and mortality associated with CMV reactivation can be reduced. Objectives: To evaluate the incidence and morbidity associated with CMV reactivation following hematopoeitic stem cell transplantation. Methodology: We retrospectively analysed 136 hematopoeitic stem cell transplant recipients at our centre for CMV reactivation and their complications. Quantification of CMV-DNA was done by PCR. CMV disease was confirmed histologically via CMV inclusion bodies or immunostaining of biopsy of the affected organ, mainly the gastrointestinal tract. Results: A total of 13 out of 136 patients (9.56%) had CMV reactivation. 6 out of 13 patients had CMV disease, 3 of which died (23.1% of patients with CMV reactivation). CMV reactivation occurred at a median duration of 52.5 days post transplantation (range 35-178 days). The gastrointestinal tract was the organ most commonly affected by CMV. The median follow-up was 14 months (range 6 - 64 months). Conclusion: Through a higher rate of sero-prevalance in developing countries, the incidence of CMV infection following hematopoeitic stem cell transplantation is comparable to that reported in Western literature. Oral valganciclovir was an effective pre-emptive therapy for CMV disease.

Abstract Cytomegalovirus (CMV) reactivation remains one of the most common and life-threatening infectious complications following allogeneic hematopoietic stem cell transplantation, despite novel diagnostic technologies, several novel prophylactic agents, and further improvements in preemptive therapy and treatment of established CMV disease. Treatment decisions for CMV reactivation are becoming increasingly difficult and must take into account whether the patient has received antiviral prophylaxis, the patient’s individual risk profile for CMV disease, CMV-specific T-cell reconstitution, CMV viral load, and the potential drug resistance detected at the time of initiation of antiviral therapy. Thus, we increasingly use personalized treatment strategies for the recipient of an allograft with CMV reactivation based on prior use of anti-CMV prophylaxis, viral load, the assessment of CMV-specific T-cell immunity, and the molecular assessment of resistance to antiviral drugs.

Graft Versus Host

The aim of the study was to systematize and summarize the current available data on ruxolitinib use in patients with myelofibrosis (MF) prior to allogeneic hematopoietic stem cell transplantation (allo-HSCT) to improve its results. The review includes data from foreign and domestic articles found in the PubMed and elibrary.ru databases describing the results of the use of ruxolitinib in patients with MF prior to allo-HSCT, including clinical cases, original scientific studies and reviews. It is reported that ruxolitinib therapy is safe, reduces mortality in the early post-transplantation period, reduces the incidence of acute and chronic graft-versus-host disease, and decreases the frequency of relapses. Clinical improvement with ruxolitinib therapy prior to allo-HSCT can be considered a prognostically favorable factor.

Abstract Introduction Multiple myeloma (MM) in very young patients is uncommon, and no treatment guidelines exist for these patients. Patients and Methods We performed a retrospective analysis of five very young myeloma patients who underwent tandem autologous hematopoietic stem cell transplantation (HSCT). Results The median age was 37 years (range = 34–40 years). A median of two leukapheresis was performed (range = 1–4). The median number of hematopoietic stem cells collected was 5.4 × 106/kg (4.4–8.2 × 106/kg). During first transplant, four patients received melphalan of 200 mg/m2 and one patient received melphalan of 140 mg/m2 (due to renal failure) as conditioning regimen. Second transplant conditioning was melphalan of 200 mg/m2 for one patient and melphalan of 140 mg/m2 for remaining four patients. Two patients were in complete remission, and two were in very good partial remission and one patient progressed to active disease at the time of tandem autologous bone marrow transplant. All patients developed significant mucositis. Neutrophil and platelet recovery was longer in tandem autologous hematopoietic stem cell transplant. More viral infections were seen in tandem transplant. Day 30 and day 100 mortality was nil. Conclusion We present data on tandem autologous HSCTs in very young patients with MM in India. Responses continued to improve in this small series.

For the last few months, various geographical regions and health sectors have been facing challenges posed by the current COVID-19 pandemic. COVID-19 has led to significant disruption in the normal functioning of potentially life-saving therapies of hematopoietic cell transplant and chimeric antigen receptor therapy. As transplant physicians are gaining more information and experience regarding the undertaking of these complex procedures during the ongoing COVID-19 pandemic, we believe it is important to discuss the challenges faced, prognostic risk factors, and outcomes of COVID-19 in post-hematopoietic stem cell transplantation patients based on the available real-world data.

BK virus is a human polyoma virus. It is acquired in early childhood and remains life-long latent in the genitourinary system. BK virus replication is more common in receiving immunosuppressive therapy receiving patients and transplant patients. BK virus could cause hemorrhagic cystitis in patients with allogeneic stem cell transplantation. Hemorrhagic cystitis is a serious complication of hematopoietic stem cell transplantation. Hemorrhagic cystitis could cause morbidity and long stay in the hospital. Diagnosis is more frequently determined by the presence of BK virus DNA detected with quantitative or real-time PCR testing in serum or plasma and less often in urine. The reduction of immunosuppression is effective in the treatment of BK virus infection. There are also several agents with anti-BK virus activity. Cidofovir is an active agent against a variety of DNA viruses including poliomyoma viruses and it is a cytosine nucleotide analogue. Intravenous immunoglobulin IgG (IVIG) also includes antibodies against BK and JC (John Cunningham) viruses. Hereby, we report three cases of hemorrhagic cystitis. Hemorrhagic cystitis developed in all these three cases of allogeneic stem cell transplantation due to acute myeloid leukemia (AML). BK virus were detected as the cause of hemorrhagic cystitis in these patients. Irrigation of the bladder was performed. Then levofloxacin 1×750 mg intravenous and IVIG 0.5 gr/kg were started. But the hematuria did not decreased. In the first case, treatment with leflunomide was started, but patient died due to refractory AML and severe graft-versus-host disease after 4th day of leflunamide and levofloxacin treatments. Cidofovir treatment and the reduction of immunosuppressive treatment decreased the BK virus load and resulted symptomatic improvement in the second case. Initiation of cidofovir was planned in the third case. Administration of cidofovir together with the reduction of immunosuppression in the treatment of hemorrhagic cystitis associated with BK virus in allogeneic stem cell transplant recipients could be a good option.

AbstractStem cells are undifferentiated cells that can divide and become differentiated. Hematopoietic stem cells cannot transform into new stem cells such as cardiomyocytes or new heart valves, but they act through paracrine effects, by secreting cytokines and growth factors that lead to an increase in contractility and overall improved function. In this case report, we present how autologous stem cell transplantation can bring two major benefits: the first refers to hematological malignancy and the second is about the improvement of the heart condition. We present the case of a 60-year-old patient diagnosed with multiple myeloma suffering from a bi-valve severe condition in which autologous stem cell transplantation led to the remission of the patient’s malignant disease and also improved the heart function.

Introduction: Allogeneic hematopoietic stem cell transplantation (HCT) is a potentially curative treatment for several malignant and non-malignant hematological diseases. However, sometimes it is challenging to find human leukocyte antigen (HLA)-matched related or unrelated donors, especially in minority populations such as Hispanics. Transplantation of T cell replete HLA haploidentical graft (HaploHCT) followed by a high dose post-transplantation cyclophosphamide (PTCy) to eradicate alloreactive T cells is an option for populations with low donor availability. HaploHCT has emerged as an effective and safe strategy in this population (Luznik L et al. BBMT 2008), but data in Hispanics is scarce. Objective: The aim of our study was to describe the clinical characteristics and assess overall survival at 100 days, 1- and 3-years of patients who underwent haploHCT in two Colombian reference centers. Methods: An observational retrospective study was conducted at two tertiary referral centers in Colombia. Patients who underwent haploHCT at Clinica FOSCAL and Centro Medico Imbanaco between January 2013 and January 2020 were selected. Demographic and clinical characteristics where analyzed using descriptive statistics. The Kaplan-Meier method was used to assess overall survival (OS) rates and the log-rank test was used to compare survival rates between groups. All data were analyzed using R statistical software®. Results: Seventy-six patients were included. Mean age at transplantation was 34 years (range 18-60). Forty-two (57.89%) patients were female. Average body mass index was 19.86kg/m2. The majority of patients (57%) had a pre-transplantation ECOG performance status of 2. The most common indication for haploHCT was acute lymphoblastic leukemia (55.26%), followed by acute myeloid leukemia (23.64%). A sibling was the donor in 69.74% of the cases. Forty-seven (61.84%) patients were ABO-matched group. Peripheral blood stem cells were the graft source in 96% of the patients. The average number of infused CD34+ cells was 11.15 x 106/kg. Fludarabine-melphalan was the most commonly used conditioning regimen (57%), followed by fludarabine-busulfan-thiotepa (39%). Graft-versus-host disease (GVHD) prophylaxis consisted of PTCy (50 mg/kg/day) on days 3 and 4 after HCT and a calcineurin inhibitor plus mycophenolate mofetil from day 5 to day 35 post-HCT. Median time to neutrophil engraftment (neutrophils > 0,5x109/L) was 15 days (range 10-33), while platelet engraftment, defined as as the second day of unsupported platelet count of ≥20 × 109, occurred at a median time of 13 days (range 5-38) post-transplantation. On day 28 post-HSCT, 93.4% of the patients had achieved 100% chimerism. OS was 91% (95%CI 84-97.5) at 100 days, 81% (95%CI 72-90) at 1-year, and 77% (95%CI 68-88) at 3-years after HaploHCT. C onclusion: The results of our haploHCT retrospective study in a Hispanic population are comparable to several other cohorts that have reported similar outcomes of haploHCT compared to HLA-matched HCT. The OS rates reported in our study suggest that haploHCT is a viable option in patients without an HLA-matched related or unrelated donor available, especially in populations with lower rates of suitable donors.
