Compliance with yellow fever and measles vaccines in the revaccination program post-hematopoietic cell transplantation. Transpl Infect Dis 2023; 25:e14098.

Abstract
INTRODUCTION Measles, mumps, rubella, and even poliomyelitis outbreaks have recently perplexed infectious disease clinicians and epidemiologists globally due to the decline in vaccination coverage rates in children and adults. Measles and yellow fever (YF) have represented an increasing burden on the Brazilian public health system in recent decades. Both diseases are preventable by live-attenuated viral vaccines (LAVV), which have restricted use in hematopoietic cell transplant (HCT) recipients. METHODS Autologous and allogeneic HCT recipients returning for regular appointments at the outpatient clinic were invited to participate in the study. Patients transplanted for at least 2 years and with a printed copy of the vaccination record were included. RESULTS We assessed the vaccination records of 273 HCT recipients after the second year of HCT (193 allogeneic and 80 autologous) and observed lower compliance with the YF vaccine (58 patients, 21.2%) than with the measles vaccine (138 patients, 50.5%, p ≤ .0001). This is the largest published series of YF vaccination in HCT recipients so far. No severe adverse events occurred. Although expected, chronic graft-versus-host disease (GVHD) did not affect the compliance with measles (p = .08) or YF vaccination (p = .7). Indeed, more allogeneic recipients received measles vaccine in comparison with autologous patients (p < .0001), suggesting that chronic GVHD was not the main reason for not being vaccinated. Children and allogeneic HCT were more likely to receive measles vaccine. Time elapsed from HCT >5 years favored both measles and YF vaccination. CONCLUSION A better understanding of the reasons for low compliance with LAVV is necessary to overcome this problem.

Abstract
Visceral leishmaniasis (VL) is a chronic infection caused by Leishmania (L.) donovani or L. infantum parasites. Despite having the infection, most individuals never develop the clinical disease and are able to control the parasite and remain asymptomatic. However, some progress to symptomatic VL, leading to death if untreated. The host immune response has a major role in determining the progression and severity of the clinical manifestations in VL; several immune biomarkers of symptomatic VL have been described with interferon-gamma release as a surrogate biomarker of host cellular immunity. However, new biomarkers to identify asymptomatic VL (AVL) are needed for the identification of people at risk for VL activation. In our study, levels of chemokine/cytokine in the supernatants of peripheral mononuclear blood cells (PBMC) from 35 AVL+ Iraq-deployed participants, stimulated in vitro with soluble Leishmania antigen for 72 h, were assessed by a bead-based assay that allows the measurement of multiple analytes. PBMC of AVL-negative military beneficiaries were used as controls. Monocyte Chemoattractant Protein-1, Monokine Induced by Gamma Interferon and Interleukin-8, were detected at high levels in AVL+ stimulated cultures from Iraq deployers compared to uninfected controls. Measurement of chemokine/cytokine levels can identify cellular immune responses in AVL+ asymptomatic individuals.

Abstract
Literature discussing endemic and regionally limited infections in recipients of haematopoietic stem-cell transplantation (HSCT) outside western Europe and North America is scarce. This Worldwide Network for Blood and Marrow Transplantation (WBMT) article is part one of two papers aiming to provide guidance to transplantation centres around the globe regarding infection prevention and treatment, and considerations for transplantation based on current evidence and expert opinion. These recommendations were initially formulated by a core writing team from the WBMT and subsequently underwent multiple revisions by infectious disease experts and HSCT experts. In this paper, we summarise the data and provide recommendations on several endemic and regionally limited viral and bacterial infections, many of which are listed by WHO as neglected tropical diseases, including Dengue, Zika, yellow fever, chikungunya, rabies, brucellosis, melioidosis, and leptospirosis.

Abstract
There is a scarcity of data on endemic and regionally limited fungal and parasitic infections in recipients of haematopoietic stem-cell transplantation (HSCT) outside western Europe and North America. This Worldwide Network for Blood and Marrow Transplantation (WBMT) Review is one of two papers aiming to provide guidance to transplantation centres worldwide regarding prevention, diagnosis, and treatment based on the currently available evidence and expert opinion. These recommendations were created and reviewed by physicians with expertise in HSCT or infectious disease, representing several infectious disease and HSCT groups and societies. In this paper, we review the literature on several endemic and regionally limited parasitic and fungal infections, some of which are listed as neglected tropical diseases by WHO, including visceral leishmaniasis, Chagas disease, strongyloidiasis, malaria, schistosomiasis, histoplasmosis, blastomycosis, and coccidioidomycosis.

Abstract
Despite developing consensus guidelines addressing immunization after hematopoietic stem cell transplantation (HSCT), studies showed deviations from recommended immunization practices commonly occur. Difference between the ideal scenario presented in guidelines and real-life scenarios is one of the most recognized barriers to implementing recommended practices. Therefore, this study aimed to evaluate pediatric allogeneic HSCT recipients' adherence to revaccination schedule and evaluate the serological status after immunization. Transplant and vaccination records of children who were followed up at least 2 years after HSCT, postvaccination antibody results of vaccine-preventable diseases were evaluated retrospectively. Total of 173 patients have enrolled in this study. Median revaccination onset time was post-transplant 15 months. Adherence to revaccination program was 30% for inactive and 11.4% for live vaccines. Oral polio vaccine was given to 22 patients, and Bacille-Calmette-Guerin vaccine was applied to 3. Seropositivity after revaccination was >90% for Hepatitis B, Hepatitis A, pertussis, and measles, and it was 88.5% for rubella, 80% for mumps and varicella. Measles seropositivity was low in children with hemoglobinopathy. In subgroup assessments of pertussis, patients vaccinated with low antigen-containing pertussis vaccine (Tdap) had higher seropositivity of adenylate cyclase toxin. Our findings revealed the importance of careful monitoring of current practices in pediatric HSCT recipients.

Abstract
BACKGROUND Infectious complications in kidney transplant recipients (KTRs) are well studied in temperate countries but remain barely known in tropical ones. The main objective of this study was to describe infection-related hospitalizations in patients living in the Amazon, where it has never been described. METHODS All KTRs residing in French Guiana between 2007 and 2018 were included retrospectively. Infection-related hospitalizations were collected in the main medical centers of the territory. RESULTS Eighty-two patients were included, and 42 were infected during the study period (51%). Eighty-seven infections were identified. The main sites of infection were urinary, in 29% of cases (25/87), and pulmonary, in 22% of cases (19/87). When documented (48/87), bacterial infections were predominant (35/48), followed by viral (8/48), fungal (4/48), and parasitic infections (1/48). Endemic so-called tropical infections accounted for 6% of infections (5/87). Histoplasma capsulatum was the most commonly isolated fungus (2/4). CONCLUSIONS This study suggests that the spectrum of infections in KTRs in French Guiana differs little from that of temperate countries. Nevertheless, some tropical infections are described. More studies on fungal infections in KTRs should be undertaken to clarify the weight of histoplasmosis in these patients.

Abstract
OBJECTIVES Visceral leishmaniasis (VL) is a progressive disease that, left untreated, is typically fatal. The purpose of this investigation was to detect Leishmania sp. infection in hemodialysis patients who had received multiple blood transfusions at a private clinic in Campo Grande, Mato Grosso do Sul state, Midwest Brazil. METHODS Fifty randomly selected volunteers were interviewed for collection of demographic, socioeconomic, and epidemiological data. Indirect immunofluorescence (titers positive when ≥1:40) and rK39 immunochromatographic tests were employed for serological investigation. RESULTS Males predominated (60%). Age ranged from 20 to 77 years. Most subjects reported being on hemodialysis for at least one year (94%) and 84% were candidates for kidney transplantation, 67% of whom were on the waiting list. Leishmania sp. infection was detected in 32%. Contact with infected dogs was the only variable associated with infection. CONCLUSIONS Under immunocompromised conditions, VL is opportunistic and potentially fatal. Despite existing risks, screening for VL is not performed in asymptomatic donors and recipients. The detection of anti-Leishmania antibodies in these patients reinforces the need for infection screening before immunosuppressive treatment is initiated to reduce not only the risks of VL development and severity, but also mortality rates in cases of reactivation of latent infection.

Abstract
Latent tuberculosis infection (LTBI) affects one-fourth of the world´s population. Hematopoietic stem cell transplantation (HSCT) recipients are at an elevated risk of developing active tuberculosis infection (ATBI). In this retrospective study of donors and HSCT recipients who underwent transplantation between February 2000 and June 2018, our aim was to determine the prevalence of LTBI and ATBI and to describe diagnostic and therapeutic strategies in an HSCT population in an endemic region. The cohort of 409 participants included 125 allogeneic HSCT (allo-HSCT) recipients, 165 autologous HSCT (auto-HSCT) recipients, and 119 HSCT donors. Patients were evaluated pre-HSCT with tuberculin skin test and thoracic imaging. LTBI was diagnosed in 26.2% of the cohort. Cases represented 20% of the auto-HSCT population, 20% of the allo-HSCT population, and 41.2% of the donor population. Pre-HSCT evaluation to rule out ATBI was performed in 62.6% of the cohort; all results were negative. Isoniazid was administered to 73.3% of those with LTBI. Within subgroups, 91.7% of HSCT recipients and 51% of donors received treatment. The median duration of therapy pre-HSCT was 70 days in recipients and 48 days in donors. The incidence of post-HSCT ATBI was 0 at 1-year follow-up. The incidence of LTBI in our population was higher than expected and still might have been underestimated owing to diagnostic test limitations. The absence of incident ATBI suggests that recipients, as opposed to donors, must receive LTBI treatment. Prevention of infectious complications in the HSCT population should be prioritized to improve clinical outcomes. Prospective data from collaborative working groups is needed to determine the best diagnostic and therapeutic approaches in this vulnerable patient population.

Abstract
Autologous stem cell transplant (ASCT) is a widely used and safe procedure to treat mostly hematologic diseases. These patients are at risk of infectious complications, which represents a major cause of morbidity and it is the second cause of mortality. This retrospective 12-year analysis of the incidence, type, and severity of infections in 266 consecutive unselected ASCT patients at our institution provides novel information addressing this issue. We included 266 ASCT procedures. Patients included in the 2006-2013 period are referred to as group 1 (ciprofloxacin prophylaxis and ceftazidime-amikacin as empirical antibiotics), and those in the 2013-2017 period are group 2 (levofloxacin prophylaxis and meropenem as empirical antibiotics). The incidence of febrile neutropenia was 72% in group 1 and 86.2% in group 2 (p = 0.004). The majority of infectious episodes were associated with fever of unknown origin: 55% in group 1 and 59% in group 2. Febrile of unknown origin episodes were 82.6% in group 1 and 80% in group 2. Significant differences between both groups were found in age, hypogammaglobulinemia, and advanced disease at ASCT. No differences were found between groups regarding the most common agent documented in positive blood cultures (Gram+ were 66.6% in group 1 and 69% in group 2 (p = 0.68)). Mortality within 100 days of transplant was low, 1.87%. Regardless of the prophylactic regimen used, most patients experience febrile episodes in the ASCT setting, fever of unknown origin is the most common infection complication, and Gram+ agents are prevalent in both groups. Mortality rates were low. According to our results, ASCT is a safe procedure and there is no clear benefit in favor of levofloxacin versus ciprofloxacin prophylaxis. Both anti-infectious approaches are acceptable, yielding similar outcomes.

Abstract
Hematopoietic stem cell transplantation (HSCT) recipients may infrequently develop parasitic infections at the time of the procedure via contamination from allograft tissue or blood products, and in the post-transplantation period through the traditional route of infection or as a reactivation caused by immunosuppression related to the transplant. To reduce risk, efforts should be directed at performing a comprehensive history, maintaining a high index of suspicion, and adhering to preventive measures. Additional strategies for the prevention, screening and careful follow-up, identification, and pre-emptive treatment of parasitic infections are required to reduce morbidity and mortality in HSCT patients.

Abstract
Dengue infection (DI) is the most important arboviral infection in the world. The majority of immunocompetent patients will have asymptomatic or mild infections, but the degree of dengue severity in kidney transplant recipients (KTx) is unknown. In this study, we report the clinical profile and outcomes of 39 dengue cases in KTx. From a total of 1,186 KTx outpatients in follow-up we reviewed clinical and laboratory records of 60 (5%) patients admitted with suspected DI initially screened by NS-1, IgM, and when possible, multiplex nested PCR. The prevalence of DI in KTx was 3% (39/1,118), with symptoms leading to hospital admission being fever, myalgia, malaise, and headache. Laboratory tests showed leucopenia, thrombocytopenia, and liver enzyme elevation. DI was confirmed by positivity of NS-1 (33%), IgM (69%), and/or RT-PCR (59%). Twenty-three patients (59%) had dengue with warning signs, and 15% had severe dengue, 2 of them with a fatal course. Acute graft dysfunction occurred in 59% (mean nadir serum creatinine: 2.9 ± 2.6mg/dL), 4 of them requiring dialysis. CMV coinfection diagnosed in 19% of the cases and patients was associated with worse clinical presentation. Our results suggest that KTx with DI presented initial physical and laboratorial profile similar to the general population. However, DI in KTx seems to have a higher risk for graft dysfunction, severe dengue, and death. Because CMV coinfection aggravates the DI clinical presentation and recovery, it must be evaluated in all cases.

Abstract
Leishmaniasis is a serious health problem in many countries, and continues expanding to new geographic areas including Europe and USA. This disease, caused by parasites of Leishmania spp. and transmitted by phlebotomine sand flies, causes up to 1.3 million new cases each year and despite efforts toward its functional dissection and treatment it causes 20–50 thousands deaths annually. Dependence of susceptibility to leishmaniasis on sex and host's genes was observed in humans and in mouse models. Several laboratories defined in mice a number of Lmr (Leishmania major response) genetic loci that control functional and pathological components of the response to and outcome of L. major infection. However, the development of its most aggressive form, visceral leishmaniasis, which is lethal if untreated, is not yet understood. Visceral leishmaniasis is caused by infection and inflammation of internal organs. Therefore, we analyzed the genetics of parasite load, spread to internal organs, and ensuing visceral pathology. Using a new PCR-based method of quantification of parasites in tissues we describe a network-like set of interacting genetic loci that control parasite load in different organs. Quantification of Leishmania parasites in lymph nodes, spleen and liver from infected F2 hybrids between BALB/c and recombinant congenic strains CcS-9 and CcS-16 allowed us to map two novel parasite load controlling Leishmania major response loci, Lmr24 and Lmr27. We also detected parasite-controlling role of the previously described loci Lmr4, Lmr11, Lmr13, Lmr14, Lmr15, and Lmr25, and describe 8 genetic interactions between them. Lmr14, Lmr15, Lmr25, and Lmr27 controlled parasite load in liver and lymph nodes. In addition, Leishmania burden in lymph nodes but not liver was influenced by Lmr4 and Lmr24. In spleen, parasite load was controlled by Lmr11 and Lmr13. We detected a strong effect of sex on some of these genes. We also mapped additional genes controlling splenomegaly and hepatomegaly. This resulted in a systematized insight into genetic control of spread and load of Leishmania parasites and visceral pathology in the mammalian organism.

Abstract
Viral infections account for a large proportion of emerging infectious diseases, and the agents included in this group consist of recently identified viruses as well as previously identified viruses with an apparent increase in disease incidence. In transplant recipients, this group can include viruses with no recognized pathogenicity in immunocompetent patients and those that result in atypical or more severe disease presentations in the immunocompromised host. In this chapter, we begin by discussing viral diagnostics and techniques used for viral discovery, specifically as they apply to emerging and rare infections in this patient population. Focus then shifts to specific emerging and re-emerging viruses in the transplant population, including human T-cell leukemia virus 1, rabies, lymphocytic choriomeningitis virus, human bocavirus, parvovirus 4, measles, mumps, orf, and dengue. We have also included a brief discussion on emerging viruses and virus families with few or no reported cases in transplant recipients: monkeypox, nipah and hendra, chikungunya and other alphaviruses, hantavirus and the Bunyaviridae, and filoviruses. Finally, concerns regarding infectious disease complications in xenotransplantation and the reporting of rare viral infections are addressed. With the marked increase in the number of solid organ and hematopoietic stem cell transplants performed worldwide, we expect a corresponding rise in the reports of emerging viral infections in transplant hosts, both from known viruses and those yet to be identified.

Abstract
Aedes mosquitoes are well adapted in domestic environments and widespread in tropical regions. Since 2015, Brazil has been experiencing a triple epidemic of dengue (DENV), chikungunya (CHKV), and Zika (ZIKV) viruses. The last 2 viruses are likely following the path of DENV, which has been endemic in most parts of the country since the 1980s. Given this triple epidemic, we proposed a prospective and collaborative study to assess the prevalence, morbidity, and mortality of DENV, CHKV, and ZIKV infections in hematopoietic stem cell transplant (HSCT) recipients and oncohematological patients. A case definition strategy (fever and rash) was used to prompt diagnostic investigation of DENV, ZIKV, and CHKV, which was accomplished by real-time polymerase chain reaction with plasma and urine samples. Clinical follow-up was performed 7 and 30 days after symptom onset. We report here the first cases of ZIKV and CHKV infections diagnosed in this ongoing study. From February to May 2016, 9 of the 26 patients (34.6%) fulfilling case definition criteria were diagnosed with DENV (3 cases), ZIKV (4 cases), or CHKV (2 cases) infections. Prolonged viremia and viruria were observed in dengue and Zika fever cases, respectively. Thrombocytopenia was the most frequent complication. Delayed engraftment was noted in 1 patient who acquired ZIKV 25 days before HSCT. All patients survived without sequelae. With the geographic expansion of arboviruses, donor and recipient screening may become mandatory. Patients living in areas where these viruses are not endemic are also at risk, since these viruses can be transmitted by blood as well as organ or tissue transplantation.

Abstract
OBJECTIVE This multicentre cross-sectional study aims to estimate the prevalence of five neglected tropical diseases (Chagas disease, filariasis, schistosomiasis, strongyloidiasis and toxocariasis) among immigrants accessing health care facilities in five Italian cities (Bologna, Brescia, Florence, Rome, Verona). METHODS Individuals underwent a different set of serological tests, according to country of origin and presence of eosinophilia. Seropositive patients were treated and further followed up. RESULTS A total of 930 adult immigrants were enrolled: 477 men (51.3%), 445 women (47.9%), eight transgender (0.8%); median age was 37.81 years (range 18-80 years). Most of them had come from the African continent (405/930, 43.5%), the rest from East Europe, South America and Asia, and 9.6% (89/930) were diagnosed with at least one of the infections under study. Seroprevalence of each specific infection varied from 3.9% (7/180) for Chagas disease to 9.7% (11/113) for toxocariasis. Seropositive people were more likely to be 35-40 years old and male, and to come from South East Asia, sub-Saharan Africa or South America. CONCLUSIONS The results of our study confirm that neglected tropical diseases represent a substantial health problem among immigrants and highlight the need to address this emerging public health issue.

Abstract
Leprosy triggers a complex relationship between the pathogen and host immune response. Endothelium plays an important role in this immune response by directly influencing cell migration to infected tissues. The objective of this work is to investigate the possible role of endothelium in M. leprae infection, correlating the characteristics of endothelial markers with the expression pattern of cytokines. Thirty-six skin biopsy samples were cut into 5-μm thick sections and stained with hematoxylin-eosin and Ziehl-Neelsen for morphological analysis and then submitted to immunohistochemical analysis using monoclonal antibodies against ICAM-1, ICAM-2, VCAM-1, and VLA-4. Immunostaining for ICAM-1 showed a significantly larger number of stained endothelial cells in the tuberculoid leprosy (9.92 ± 1.11 cells/mm2) when compared to lepromatous samples (5.87 ± 1.01 cells/mm2) and ICAM-2 revealed no significant difference in the number of endothelial cells expressing this marker between the tuberculoid (13.21 ± 1.27 cells/mm2) and lepromatous leprosy (14.3 ± 1.02 cells/mm2). VCAM-1-immunostained showed 18.28 ± 1.46/mm2 cells in tuberculoid leprosy and 10.67 ± 1.25 cells/mm2 in the lepromatous leprosy. VLA-4 exhibited 22.46 ± 1.38 cells/mm2 in the tuberculoid leprosy 16.04 ± 1.56 cells/mm2 in the lepromatous leprosy. Samples with characteristics of the tuberculoid leprosy exhibited a larger number of cells stained with ICAM-1, VCAM-1 and VLA-4, demonstrating the importance of these molecules in the migration and selection of cells that reach the inflamed tissue.

Abstract
Leishmaniasis occurs in <1% of solid organ and hematopoietic stem cell transplant recipients in endemic countries in which transplants are performed. Visceral leishmaniasis (VL) makes up the bulk of reported cases. The onset generally occurs months after transplantation and the mode of acquisition is often impossible to determine, but de novo vector-borne infection and reactivation of inapparent infection are thought to be the principal means. The potential role of clinically inapparent donor infection is uncertain and screening is not currently recommended, nor is it recommended for recipients from endemic areas, some of whom may have detectable circulating protozoan nucleic acid. While transplant recipients with VL often present with the non-specific findings of fever and cytopenia, the additional presence of hepatosplenomegaly in patients from endemic areas should lead to a directed diagnostic evaluation with bone marrow examination and PCR testing of marrow and peripheral blood having a high yield. Management may often be complicated by the presence of concomitant infections. A lipid formulation of amphotericin B is the preferred treatment, especially for VL, but the relapse rate in transplant recipients is approximately 25%. PCR monitoring of blood for either secondary prophylaxis or preemptive therapy requires further study.

Abstract
A small yet diverse xanthone library was build and computationally docked against wild type Pf-DHFR by Molegro Virtual Docker (MolDock). For analysis of results an integrated approach based on re-ranking, scaling (based on heavy atom counts), pose clustering and visual inspection was implemented. Standard methods such as self-docking (for docking), EF analysis, average rank determinations (for size normalization), and cluster quality indices (for pose clustering) were used for validation of results. Three compounds X5, X113A and X164B displayed contact footprints similar to the known inhibitors with good scores. Finally, 16 compounds were extracted from ZINC data base by similarity based screening, docking score and drug/lead likeness. Out of these 16 compounds, 11 displayed very close contact footprints to experimentally known inhibitors, indicating there potential utility in further drug discovery efforts.

Abstract
Haematopoietic cell transplants are done by more than 1500 transplant centres in 75 countries, mostly for life-threatening haematological disorders. However, transplant technology and access are not uniformly distributed worldwide. Most transplants are done predominately in Europe, North America and some Asian countries. We review transplant activity in Latin America, a geographic region with a population of >600 million persons living in countries with diverse economic and social development levels. These data indicate a 20-40-fold lower frequency of transplants in Latin America compared with Europe and North America. We show that although economics, infrastructure and expertise are important limitations, other variables also operate. Changes in several of these variables may substantially increase transplant activity in Latin America.

Abstract
Leprosy is an infectious-contagious disease whose clinical evolution depends on the immune response pattern of the host. Adhesion molecules and leukocyte migration from blood to tissue are of the utmost importance for the recognition and elimination of infectious pathogens. Selectins are transmembrane glycoproteins that share a similar structural organization and can be divided into three types according to their site of expression. The biopsies were cut into 5μm thick sections and submitted to immunohistochemistry using antibodies against E-selectin and P-selectin. The number of E-selectin-positive cells was significantly higher in the tuberculoid form than in the lepromatous form. The immunostaining pattern of P-selectin differed from that of E-selectin. Analysis showed a larger number of endothelial cells expressing CD62P in the lepromatous form compared to the tuberculoid form. The presence of these adhesins in the endothelium contributing to or impairing the recruitment of immune cells to inflamed tissue and consequently influences the pattern of immune response and the clinical presentation of the disease.

Ultrastructural analysis of Leishmania infantum chagasi promastigotes forms treated in vitro with usnic acid. ScientificWorldJournal 2015; 2015:617401.

Abstract
Leishmaniasis is considered by the World Health Organization as one of the infectious parasitic diseases endemic of great relevance and a global public health problem. Pentavalent antimonials used for treatment of this disease are limited and new phytochemicals emerge as an alternative to existing treatments, due to the low toxicity and cost reduction. Usnic acid is uniquely found in lichens and is especially abundant in genera such as Alectoria, Cladonia, Evernia, Lecanora, Ramalina, and Usnea. Usnic acid has been shown to exhibit antiviral, antiprotozoal, antiproliferative, anti-inflammatory, and analgesic activity. The aim of this study was to evaluate the antileishmanial activity of usnic acid on Leishmania infantum chagasi promastigotes and the occurrence of drug-induced ultrastructural damage in the parasite. Usnic acid was effective against the promastigote forms (IC50 = 18.30 ± 2.00 µg/mL). Structural and ultrastructural aspects of parasite were analyzed. Morphological alterations were observed as blebs in cell membrane and shapes given off, increasing the number of cytoplasmic vacuoles, and cellular and mitochondrial swelling, with loss of cell polarity. We concluded that the usnic acid presented antileishmanial activity against promastigote forms of Leishmania infantum chagasi and structural and ultrastructural analysis reinforces its cytotoxicity. Further, in vitro studies are warranted to further evaluate this potential.

Abstract
Leishmaniasis is a disease of the immunocompetent population, more often affecting infants and young children. However, the number of leishmaniasis cases associated with immunosuppression has increased over the last 20 years. The visceral form of the disease, visceral leishmaniasis (VL), is identified as an opportunistic infection in immunosuppressed individuals, occurring mainly after solid organ transplantation, especially in renal transplant recipients. Limited data are available about VL after hematopoietic stem cell transplantation (HSCT). We report the cases of 3 patients with late VL after allogeneic HSCT, and review the literature.

Abstract
Advances in hematopoietic cell transplantation (HCT) technology and supportive care techniques have led to improvements in long-term survival after HCT. Emerging indications for transplantation, introduction of newer graft sources (eg, umbilical cord blood) and transplantation of older patients using less intense conditioning regimens have also contributed to an increase in the number of HCT survivors. These survivors are at risk for developing late complications secondary to pre-, peri-, and posttransplantation exposures and risk factors. Guidelines for screening and preventive practices for HCT survivors were published in 2006. An international group of transplantation experts was convened in 2011 to review contemporary literature and update the recommendations while considering the changing practice of transplantation and international applicability of these guidelines. This review provides the updated recommendations for screening and preventive practices for pediatric and adult survivors of autologous and allogeneic HCT.

Abstract
Literature on tuberculosis (TB) occurring in recipients of Hematopoietic Stem Cell Transplant (HSCT) is scanty even in countries where TB is common. Most reports of TB in HSCT patients were from ASIA, in fact the TB incidence ranging from 0.0014 (USA) to 16% (Pakistan). There are few reports of TB diagnosis during the first two weeks after HSCT; most of cases described in the literature occurred after 90 days of HSCT, and the lung was the organ most involved. The mortality ranged from 0 to 50% and is higher in allogeneic HSCT than in autologous. There is no consensus regarding the screening with tuberculin skin test or QuantiFERON-TB gold, primary prophylaxis for latent TB, and whether the epidemiologic query should be emphasized in developing countries with high prevalence of TB.

Abstract
INTRODUCTION In Pakistan, dengue viral infection has become hyper-endemic. Renal transplantation is also expanding. We aimed to study dengue in renal transplant recipients (RTR). METHODS We conducted a study of RTR reported to be anti-dengue immunoglobulin-M antibody positive from January 2009 to December 2010 at our institution in Karachi and follow their clinical course and outcome. RESULTS Median age was 28 years; 75 (73.7%) were males. Clinical presentation included fever in 82 (80.4%), gastrointestinal symptoms in 35 (34.3%), hemorrhagic complications in 9 (8.8%), and thrombocytopenia in 97 (95%), which was of >15 days duration in 24%. Fever was seen less frequently in patients on high-dose (>7.5 mg) steroids as compared with low-dose (≤7.5 mg) steroids. Forty-four patients (43%) had primary and 58 (56.8%) had secondary dengue infection. Dengue fever (DF) occurred in 90 (88%), and dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS) occurred in 12 (11.7%). DHF/DSS was seen in 3 (6.8%) of those with primary and in 9 (15.5%) of those with secondary infection (P < 0.22). In secondary infection, patients on cyclosporine-containing regimen had less severe disease, with DHF/DSS in 22% as opposed to DF in 59% (P < 0.04). Of 102 RTR, 68 (66.7%) had graft dysfunction, 5 of whom died. Of the remaining 63, in 54 patients (85.7%) creatinine returned to baseline by an average of 12.6 days. Of 102 patients, 95 (93%) recovered and 7 (6.9%) died, 6 of whom had bacteremia with sepsis and 1 had respiratory failure. None died due to dengue infection alone. CONCLUSION In conclusion, in RTR without life-threatening co-morbidities, the clinical course of dengue infection is mild, with good recovery and preserved renal function.

Abstract
In this position paper, the European Society for Clinical Microbiology and Infectious Diseases, Study Group on Clinical Parasitology, summarizes main issues regarding the management of imported malaria cases. Malaria is a rare diagnosis in Europe, but it is a medical emergency. A travel history is the key to suspecting malaria and is mandatory in patients with fever. There are no specific clinical signs or symptoms of malaria although fever is seen in almost all non-immune patients. Migrants from malaria endemic areas may have few symptoms.Malaria diagnostics should be performed immediately on suspicion of malaria and the gold- standard is microscopy of Giemsa-stained thick and thin blood films. A Rapid Diagnostic Test (RDT) may be used as an initial screening tool, but does not replace urgent microscopy which should be done in parallel. Delays in microscopy, however, should not lead to delayed initiation of appropriate treatment. Patients diagnosed with malaria should usually be hospitalized. If outpatient management is preferred, as is the practice in some European centres, patients must usually be followed closely (at least daily) until clinical and parasitological cure. Treatment of uncomplicated Plasmodium falciparum malaria is either with oral artemisinin combination therapy (ACT) or with the combination atovaquone/proguanil. Two forms of ACT are available in Europe: artemether/lumefantrine and dihydroartemisinin/piperaquine. ACT is also effective against Plasmodium vivax, Plasmodium ovale, Plasmodium malariae and Plasmodium knowlesi, but these species can be treated with chloroquine. Treatment of persistent liver forms in P. vivax and P. ovale with primaquine is indicated after excluding glucose 6 phosphate dehydrogenase deficiency. There are modified schedules and drug options for the treatment of malaria in special patient groups, such as children and pregnant women. The potential for drug interactions and the role of food in the absorption of anti-malarials are important considerations in the choice of treatment.Complicated malaria is treated with intravenous artesunate resulting in a much more rapid decrease in parasite density compared to quinine. Patients treated with intravenous artesunate should be closely monitored for haemolysis for four weeks after treatment. There is a concern in some countries about the lack of artesunate produced according to Good Manufacturing Practice (GMP).

Abstract
Blood transfusion and transplantation may represent efficient mechanisms of spreading infectious agents to naive populations. In the developed countries, as a consequence of globalization, several factors such as international commerce, tourism, and immigration have acted as important features for the emergence or reemergence of infectious diseases previously referred to as tropical. This article reviews the relevant bacterial, protozoan and viral infections that are more frequently associated with blood transfusion and/or solid organ or marrow transplantation and may affect susceptible populations worldwide.

Abstract
Zoonoses include a broad range of diseases, that are becoming of great interest, due to the climate changing, that cause the adaptation of vectors to new niches and environments. Host immune responses play a crucial role in determining the outcome of infections, as documented by expansion of antigen-specific T cells during several zoonotic infections. Thus, understanding of the contribution of antigen-specific T-cell subsets in the host immune response is a powerful tool to evaluate the different immunological mechanisms involved in zoonotic infections and for the development of effective vaccines. In this paper we discuss the role of T cells in some eukaryotic and prokaryotic infectious models.

Abstract
Leishmaniasis due to Leishmania infantum (syn. L. chagasi) infection is a zoonotic disease present mainly in Mediterranean basin, central Asia and Brazil. Besides a limited number of human cases of clinical visceral leishmaniasis, a great number of infections remains asymptomatic. In this review, the prevalence of asymptomatic carriers of L. infantum was evaluated worldwide using parasitological methods or indirect testing such as a skin test or serology. The consequences of the presence of asymptomatic carriers on parasite transmission by blood donation or the development of clinical visceral leishmaniasis in immunocompromised individuals and its possible role as reservoir are discussed.

Abstract
Chagas disease, or American trypanosomiasis, is a parasitic infection caused by the flagellate protozoan Trypanosoma cruzi, an organism that is endemic to Latin America. While Chagas disease is primarily a vector-borne illness, new cases are emerging in non-endemic areas due to globalization of immigration and non-vectorial transmission routes. This article discusses the mode of transmission, evolving epidemiology, pathogenesis, diagnosis, treatment and prevention and control of the disease.

Abstract
Malaria is an unusual complication after hematopoietic stem cell transplantation in non-endemic countries. However, transplant candidates, recipients and donors living in endemic regions frequently report previous episodes of malaria. This fact could represent an important risk for immunosuppressed recipients that could develop severe malaria cases. We report a case of hematopoietic stem cell transplant (HSCT) in which the donor had a history of previous malaria, and close monitoring was performed before and after procedure by parasitological and molecular tests. The donor presented Plasmodium vivax in thick blood smears one month after transplant and was treated according to Brazilian Health Ministry guidelines. The polymerase chain reaction (PCR) was able to detect malaria infection in the donor one week earlier than thick blood film. Even without positive results, the recipient was pre-emptively treated with chloroquine in order to prevent the disease. We highlight the importance of monitoring recipients and donors in transplant procedures with the aim of reducing the risk of malaria transmission.
