Abstract
Background Autologous hematopoietic stem cell transplantation (aHSCT) is a treatment option for a selected group of systemic sclerosis (SSc) patients with good available evidence but can be associated with considerable morbidity and mortality. The aim of this study was to describe infectious complications and distinct immune reconstitution patterns after aHSCT and to detect risk factors in lymphocyte subsets, which are associated with an elevated rate of infections after aHSCT. Methods Seventeen patients with SSc were included in this single-center retrospective cohort study. Clinical and laboratory data was collected before and for 12 months after aHSCT, including immunophenotyping of peripheral whole blood by fluorescence-activated cell sorting. Results Cytomegalovirus (CMV) reactivations were common in CMV-IgG-positive patients (50%) and needed treatment. Mycotic infections occurred in 17.6%. One patient died (resulting in a mortality of 5.9%) due to pneumonia with consecutive sepsis. All patients showed decreased T helper cells (CD3+/CD4+) and within the B cell compartment decreased post-switched memory B cells (CD19+/CD27+/IgD−) and elevated naïve B cells (CD19+/CD27−/IgD+) until 12 months after aHSCT. Patients who developed infections had significantly lower B cells before aHSCT than patients who did not develop infections. Conclusion After aHSCT, monitoring for infectious complications, especially for CMV reactivations, is crucial as the reconstitution of the immune system takes longer than 12 months. Low peripheral B cells might be a risk factor for an elevated infection rate.

Varicella zoster virus reactivation after autologous SCT is a frequent event and associated with favorable outcome in myeloma patients. Bone Marrow Transplant 2015; 50:573-8.

Abstract
The occurrence of varicella zoster virus (VZV) reactivation is increased after allogeneic transplantation, whereas limited data are available for herpes zoster (HZ) after autologous SCT (ASCT). We determined the incidence and the prognostic significance of HZ and its correlation with VZV serology in 191 consecutive myeloma patients undergoing high-dose melphalan chemotherapy with ASCT. We found that VZV reactivation occurred in 57 (30%) patients, in 8.5% during induction and in 21.5% after ASCT peaking at 8 months after ASCT. Disease burden due to HZ was assessed as high or rather high in 70% of the patients. By immune fluorescence and Serion Elisa VZV IgG assessment, 90.8% of all patients had specific anti-VZV antibodies at ASCT. Lower specific antibody titers at transplantation were observed in patients with HZ after ASCT than in those without reactivation (P=0.009). Finally, OS was better in myeloma patients with HZ after ASCT compared with patients without HZ (P=0.007). Our data indicate that VZV reactivation after ASCT is a frequent event carrying a significant disease burden and it is associated with improved survival. Low levels of specific VZV antibodies at ASCT suggest increased vulnerability for VZV reactivation.

Abstract
Infection represents an important cause of morbidity after autologous hematopoietic stem cell transplantation (HSCT). Immunodeficiency is the key risk factor and results from interplay between the underlying disease and its therapy. Various defects in the immune system coexist in HSCT recipients. In the early post-transplant period, neutropenia, oral and gastrointestinal mucositis, and the presence of central venous catheters are the main risk factors. Bacterial infections predominate, and the agents and antibiotic susceptibility profiles vary widely in different regions. Invasive candidiasis is infrequent with fluconazole use, but the incidence of invasive aspergillosis is on the rise, mainly in patients receiving purine analogues or intensive chemotherapy before transplant. In the post-engraftment period, infections are less frequent, but may contribute to significant non-relapse mortality. The dynamics of immune reconstitution drives the risk for infection in this period. The most frequent infections are varicella-zoster virus disease and respiratory tract infections. Assessment of the risk of infection in each period and the identification of patients at higher risk of specific infections are critical to the appropriate management of infectious complications after autologous hematopoietic stem cell transplantation.

Abstract
Purpose To assess whether diabetes is a risk factor for herpes zoster (HZ). Methods We conducted a retrospective cohort study using the Integrated Health Care Information Services database, during the period 1997–2006. A type I diabetes cohort, a type II diabetes cohort and two non-diabetic cohorts matched for date of enrolment and duration of follow-up were defined. HZ and diabetes were defined using a combination of ICD-9 and prescription drug codes. Individuals with immunosuppressive conditions or treatments were excluded. Cox Proportional Hazards regression analysis using a stepwise method with backward elimination was applied to estimate the hazard ratios (HR) of HZ, including age, gender and co-morbidities as covariates. Results The study population comprised 380,401 and 20,397 type II and type I diabetic subjects respectively, as well as 1,521,604 and 81,588 matched controls. The median ages were 55, 35, 33 and 29 years, respectively. HZ incidence was 4.59, 2.13, 1.97, and 1.82 per 1,000 person-years, respectively. There was no evidence of an impact of type I diabetes on the risk of HZ. Type II diabetes was associated with an increased risk for HZ in subjects ≥65 (HR 3.12; 95 % CI 2.77–3.52, adjusted for gender) and in subjects between 40 and 64 (HR 1.51; 95 % CI 1.42–1.61) years of age. Cardiac disease and chronic pulmonary disease were also risk factors (HR 1.92; 95 % CI 1.73–2.13 and HR 1.52; 95 % CI 1.38–1.67) in non-diabetic subjects. Conclusions This study suggests that type II diabetes is associated with an increased risk of developing HZ, which was particularly high in adults 65 years and older and moderately increased in adults under 65 years of age.

Abstract
INTRODUCTION Advances in autologous hematopoietic stem cell transplantation (HSCT) over the past 20 years may have had an impact on the morbidity and mortality associated with infections post transplant. PATIENTS AND METHODS We sought to retrospectively analyze the epidemiology of the first episode of bacterial, fungal, viral, or parasitic infections 0-30 days post transplant in a cohort of 320 children and adolescents who underwent autologous HSCT in a single institution, between 1990 and 2009 for solid tumors or lymphoma, and in 65 children transplanted for acute leukemia during the same period. RESULTS Infections occurred in 66 (21%) patients with solid tumors or lymphoma. Bacterial infections occurred in 33 (10%) including bacteremia in 23 (7%), and viral infections in 34 (11%) patients. Gram-positive bacterial infections were more prevalent than gram-negative bacterial infections (P = 0.03). Infections caused by fungal or parasitic pathogens were uncommon. The decade when transplant was performed (1990-1999 vs. 2000-2009) had no impact on the incidence of bacterial (P = 0.41) or viral (P = 0.47) infection. Between 1990 and 1999, a total of 60 (92%) children were transplanted for leukemia, and 5 (8%) in the 2000-2009 period (P < 0.0001). Infections occurred in 32 (49%) patients. Bacterial (P = 0.004), candidal (P = 0.003), and herpes simplex viral (P = 0.03) infections were more common in patients transplanted for leukemia. In patients transplanted for leukemia, 3 deaths occurred attributed to infection, all before 2000. CONCLUSION Changes in epidemiology of infection are likely a result of decline in autologous transplantation for childhood leukemia in the recent era. Autologous transplantation for solid tumors or lymphoma was not associated with mortality from early infections at our institution.

Abstract
BACKGROUND Factors affecting progenitor cell mobilization in patients with non-Hodgkin's lymphoma (NHL) and Hodgkin's lymphoma (HL) are incompletely understood. The aim of this retrospective study was to determine which factors are crucial for effective mobilization and collection of autologous peripheral blood stem cells (PBSC) prior to transplantation in Chinese patients. PATIENTS AND METHODS A total of 239 patients with lymphoma (198 NHL and 41 HL patients) underwent PBSC collection after mobilization with granulocyte-colony-stimulating factor (G-CSF) or G-CSF plus chemotherapy priming. RESULTS Patient characteristics at diagnosis and transplant, including low Eastern Cooperative Oncology Group score (P = 0.013), lack of extranodal invasion (P = 0.034), previously administered radiotherapy regimens (P = 0.040), treatment with platinum prior to mobilization (P = 0.042), previous chemotherapy regimens (P = 0.001) and cycles (P < 0.001), and chemotherapy regimens (P < 0.001) were statistically significant for successful mobilization in multivariate analysis. Premobilization factors, including previous radiotherapy (P = 0.009), previous chemotherapy regimens (P = 0.043) and cycles (P = 0.039), low platelet count prior to mobilization (P = 0.042), and lower CD34+ cells in peripheral blood (PB) (P = 0.050) or bone marrow (BM) (P = 0.007) were considered possibly predictive of poor mobilization. We found the patients who had chemosensitive lymphoma had worse progress-free survival (PFS) than the patients with initial treatment and high risks (P = 0.017). CONCLUSION Our analysis showed that high amounts of chemotherapy, radiotherapy, low platelet count, chemosensitive recurrent patients, combination chemotherapy plus G-CSF and low CD34+ cells in BM prior to mobilization could emerged as important predictive factors for mobilization failure in Chinese patients with NHL and HL.

Abstract
PURPOSE OF REVIEW Systemic sclerosis (SSc) remains one of the last severe autoimmune disease with a poor prognosis and modest response to immunosuppressive therapy. Mortality in severe diffuse disease with internal organ involvement is elevated. Autologous hematopoietic transplantation (HSCT) has emerged in the last decade as a promising disease-modifying treatment. RECENT FINDINGS In phase I/II trials, HSCT has demonstrated to induce impressive reversal of skin fibrosis, neoangiogenesis, improved functionality and quality of life, and stabilization of internal organ function. Treatment-related mortality was reduced over time by better pretransplant evaluation and by treating patients earlier in disease. SUMMARY Two out of three randomized trials of autologous HSCT for SSc have been concluded: the nonmyeloablative American Systemic Sclerosis Immune Suppression versus Transplant, and Autologous Stem cell Transplantation International Scleroderma. The myeloablative Scleroderma Cyclophosphamide versus Transplant instead is still recruiting patients. The soon expected results from these trials should clarify the role of autologous HSCT in the challenging management of severe SSc.

Abstract
Autologous and allogeneic hematopoietic stem cell transplantation (HSCT) can be used in the management of patients with autoimmune disorders. Experience gained in adults has helped to better define the conditioning regimens required and appropriate selection of patients who are most likely to benefit from autologous HSCT. The field has been shifting toward the use of safer and less intense nonmyeloablative regimens used earlier in the disease course before patients accumulate extensive irreversible organ damage. This article reviews the experience of using autologous HSCT in treating the most common childhood autoimmune and rheumatic diseases, primarily juvenile idiopathic arthritis, systemic lupus erythematosus, and diabetes mellitus.

Abstract
PURPOSE Previously, we showed that adoptive transfer of in vivo vaccine-primed and ex vivo (anti-CD3/anti-CD28) costimulated autologous T cells (ex-T) at day +12 after transplant increased CD4 and CD8 T-cell counts at day +42 and augmented vaccine-specific immune responses in patients with myeloma. Here, we investigated the safety and kinetics of T-cell recovery after infusing ex-T at day +2 after transplant. EXPERIMENTAL DESIGN In this phase I/II two-arm clinical trial, 50 patients with myeloma received autografts after high-dose melphalan followed by infusions of ex-T at day +2 after transplant. Patients also received pretransplant and posttransplant immunizations using a pneumococcal conjugate vaccine only (arm B; n = 24) or the pneumococcal conjugate vaccine plus an HLA-A2-restricted microltipeptide vaccine for HLA-A2(+) patients (arm A; n = 26). RESULTS The mean number of T cells infused was 4.26 x 10(10) (range, 1.59-5.0). At day 14 after transplant, the median CD3, CD4, and CD8 counts were 4,198, 1,545, and 2,858 cells/microL, respectively. Interleukin (IL)-6 and IL-15 levels increased early after transplant and IL-15 levels correlated significantly to day 14 T-cell counts. Robust vaccine-specific B- and T-cell responses were generated. T-cell infusions were well tolerated with no effect on hematopoietic recovery. Eight patients (16%) developed a T-cell "engraftment syndrome" characterized by diarrhea and fever that was clinically and histopathologically indistinguishable from grade 1 to 3 acute graft-versus-host disease (GVHD) of the gastrointestinal tract (seven patients) and/or grade 1 to 2 cutaneous GVHD (four patients). CONCLUSIONS Adoptive T-cell transfers achieve robust T-cell recovery early after transplant and induce moderate-to-severe autologous GVHD in a subset of patients.

Abstract
CD34+-selected peripheral blood progenitor cells (PBPCs) may not only reduce contaminated tumor cells but also compromise immunologic reconstitution and increase incidence of infections after transplantation. We analyzed the incidence of virus reactivation in CD34+-selected PBPCs autologous transplantation. From December 2001 to December 2004, ten high-risk aggressive non-Hodgkin's lymphoma (NHL) patients were enrolled in a program of high-dose chemotherapy plus autologous CD34+-selected PBPCs support. Viral screening studies, including clinical symptoms, physical examinations, hepatitis B virus (HBV)-DNA, cytomegalovirus (CMV)-polymerase chain reaction (PCR), rapid diagnosis of fluorescent antibody stain for herpes-simplex virus (HSV), and viral culture from blood, fluid or tissue were performed weekly during the first 3 months and then monthly for 1 year. Two of four patients (50%) who were HBV carriers developed HBV reactivation. The other two HBV carriers who received prophylactic lamivudine therapy did not develop HBV reactivation. Two patients (20%) developed cytomegalovirus (CMV) infection, and three patients (30%) developed HSV infection in total ten serum-positive patients. The possibility of virus reactivation might increase in NHL patients undergoing autologous CD34+-selected PBPC transplantation. Administering prophylactic antivirus therapy and closely following patient's clinical viral complications should be considered.

Abstract
BACKGROUND Reduced CD4 T lymphocytes counts can be observed in HIV infection and in patients undergoing autologous haematopoietic stem cell transplantation (ASCT). Nevertheless, whereas opportunistic infections (OI) are frequent in HIV-infected individuals with low cell counts, OI are uncommon in ASCT patients. METHODOLOGY/PRINCIPAL FINDINGS To verify whether this observation could be secondary to intrinsic HIV-correlated T cell defects, we performed in-depth immunologic analyses in 10 patients with comparable CD4 counts in whom lymphopenia was secondary either to HIV-infection or ASCT-associated immunosuppressive therapy and compared them to age-matched healthy subjects. Results showed the presence of profound alterations in CD4+ T lymphocytes in both groups of patients with respect to healthy controls. Thus, a low percentage of CCR7+ CD4+ T cells and a compensative expansion of CD45RA-CCR7- CD4+ T cells, a reduced IL-2/IFN-gamma cytokine production and impaired recall antigens-specific proliferative responses were detected both in ASCT and HIV patients. In stark contrast, profound differences were detected in CD8+ T-cells between the two groups of patients. Thus, mature CD8+ T cell prevailed in ASCT patients in whom significantly lower CD45RA-CCR7- cells, higher CD45RA+CCR7- CD8+ cells, and an expansion of CCR7+CD8+ cells was detected; this resulted in higher IFN-gamma +/TNFalpha production and granzyme CD8+ expression. The presence of strong CD8 T cells mediated immune responses justifies the more favorable clinical outcome of ASCT compared to HIV patients. CONCLUSION/SIGNIFICANCE These results indicate that CD8 T cells maturation and functions can be observed even in the face of a profound impairment of CD4+ T lymphocytes in ASCT but not in HIV patients. Primary HIV-associated CD8 defects or an imprinting by an intact CD4 T cell system in ASCT could justify these results.

Abstract
Twenty autologous stem cell transplant recipients were vaccinated with three doses of Diphtheria-Tetanus-Poliomyelitis vaccine and conjugated Haemophilus influenzae type b (Hib) vaccine. Pneumococcal vaccination consisted of two doses of conjugated vaccine followed by a single dose of polysaccharide vaccine, at 6, 8 and 14 months after transplantation, respectively. Mean anti-tetanus, anti-Hib and anti-pneumococcal IgG antibodies significantly increased after each vaccination. Response rates after the full vaccination schedule were 94%, 78% and 61% for Hib, conjugated 7-valent pneumococcal vaccine and non-conjugated 23-valent pneumococcal vaccine, respectively. Three months after transplantation, CD16(+)CD56(+) NK cells were in the normal range and remained so. The total number of T lymphocytes at 3 months was and remained in the normal range. The mean CD4/CD8 ratio was 0.43 at 3 months post aSCT and, while gradually increasing, remained subnormal. The mean number of CD19(+) B lymphocytes significantly increased during the study period. Patients with CD19 counts <0.10 x 10(9)L(-1) required at least two Hib vaccinations to show a response, while the majority of patients with CD19 counts > or = 0.20 x 10(9)L(-1) showed a response to Hib after one vaccination only. Thus, a minimum threshold level of CD19(+) cells appears to be required for adequate responses to vaccination.

Abstract
The conditioning regimens for autologous SCT (auto-SCT) lead to impairment of the immune system and concomitant increase in susceptibility to infections. We studied the recovery of cellular immunity by in vitro analysis of T-cell proliferation and cytokine production profiles during the first 15 months after auto-SCT in patients with multiple myeloma and non-Hodgkin's lymphoma. PBMC were collected at 6, 9 and 15 months after transplantation and stimulated with a combination of CD2 and CD28 monoclonal antibodies, with PHA or with tetanus toxoid as recall antigen. A multiplex enzyme linked immunoassay was used to determine levels of Th1 cytokines IL-2, IFN-gamma and tumour-necrosis factor-alpha (TNF-alpha), Th2 cytokines IL-4, IL-5 and IL-13, the regulatory cytokine IL-10 and the proinflammatory cytokines IL-1alpha, IL-1beta, IL-6 and the chemokine IL-8. T-cell proliferation progressively increased from 6 to 15 months after auto-SCT. Overall, cytokine production increased after auto-SCT. Production of Th2 cytokines IL-5 and IL-13 was superior to production of Th1 cytokines IFN-gamma and TNF-alpha. We hypothesize that prolonged impairment of IFN-gamma production might contribute to the relatively high incidence of viral infections after auto-SCT.
