- Visceral leishmaniasis (VL) is a life-threatening disease characterized by uncontrolled parasitization of the spleen, liver, and bone marrow. Interleukin (IL)-10 has been implicated in the suppression of host immunity in human VL based on the elevated levels of IL-10 observed in plasma and lesional tissue, and its role in preventing clearance of Leishmania donovani in murine models of VL. The aim of this study was to identify the cellular source of IL-10 in human VL and determine if CD4+CD25+ (Foxp3high) regulatory T (T reg) cells are associated with active disease. We analyzed surface marker and gene expression in peripheral blood mononuclear cells and splenic aspirates from Indian VL patients before and 3–4 wk after treatment with Amphotericin B. The results did not point to an important role for natural CD4+CD25+ (Foxp3high) T reg cells in human VL. They did not accumulate in and were not a major source of IL-10 in the spleen, and their removal did not rescue antigen-specific interferon γ responses. In contrast, splenic T cells depleted of CD25+ cells expressed the highest levels of IL-10 mRNA and were the predominant lymphocyte population in the VL spleen. The elevated levels of IL-10 in VL plasma significantly enhanced the growth of L. donovani amastigotes in human macrophages. The data implicate IL-10–producing CD25−Foxp3− T cells in the pathogenesis of human VL.

An evaluation of pharmacist contribution to an oncology ward in a Swedish hospital
- 2006

- Aim. The aim of this project was to establish the importance of a pharmacist in the health-care team in improving drug use in an oncology ward in the Department of Oncology, Karolinska University Hospital, Stockholm, Sweden. Methods and patients. The pharmacist participated in the medical round in the mornings and worked as a member of the health-care team. Drug-related problems (DRPs) were identified by drug chart reviews based on data from medical files, laboratory tests and interviews with patients and/or relatives. A questionnaire to physicians and nurses was used to evaluate their experiences of the pharmacist’s contribution to the oncology ward. Results. In total, 114 DRPs were identified in 58 patients. For each DRP, the pharmacist gave proposals for solutions. Sixty-eight suggestions out of 114 (59.6%) were implemented by the physician. Two suggestions (1.8%) were partly followed. For 32 suggestions (28.0%) it was unclear if they had caused any change in medication. Twelve suggestions (10.5%) were not followed. Most of the physicians and nurses acknowledged the pharmacist’s contribution to improved drug use in the ward. Conclusion. A pharmacist can improve drug use in an oncology ward as a member of the health-care team. The pharmacist contributes with a systematic focus on the patient from a drug perspective.

Assessment of a time-of-flight detection technique for measuring small velocities of cold atoms
- 2009

- A low noise time-of-flight detection system for laser cooled atoms has been constructed and incrementally optimized. Here, a thorough description of the construction is presented along with an analysis of the capabilities of the system. The quality of the detection (the resolution, the reproducibility, the sensitivity, etc.) is crucial for, e.g., the ability to see details in the velocity distribution profile, which is of interest for fundamental studies of statistical physics and of the laser cooling processes, and for detection of small initial velocities of an atomic cloud, important, e.g., when studying small drifts induced by Brownian motors and ratchets. We estimate the signal-to-noise ratio of our signal to be better than 1000:1 for a typical single shot, and we discuss the effect of the initial atomic cloud size, the probe size, and the effects of the wave packet spread during the fall time on the measured quantities. We show that the shape of the velocity distribution is well conserved during the mapping done in the detection, i.e., in the convolution with the probe beam, and that velocities as small as a few percent of the single photon recoil velocity can be resolved.

Tracing immunity to human leishmaniasis

- People who have recovered from leishmaniasis are believed to have long-lasting protection against subsequent infection. Understanding the immunological changes that are associated with protection from cure of and susceptibility to the disease are fundamental to both designing and evaluating vaccine candidates against the leishmaniases. In the quest for a vaccine against leishmaniasis, appropriate surrogate markers of immunity would be valuable and cost effective. Biomarkers would ease screening and selection of potentially efficient vaccine candidates. Moreover, biomarkers of disease may be used to monitor disease and aid therapeutic prognosis. This would be useful in the evaluation of both existing and new drugs, making invasive post-treatment evaluation redundant. Biomarkers may also be indicative of the severity of the disease and may be able to predict the outcome of an infection and indicate whether the patient will spontaneously recover, exhibit mild symptoms or if the disease is disseminating and will be severe. In this article we discuss the immunological changes associated with different forms of human leishmaniasis and the value of appropriate immunological biomarkers in finding an effective vaccine and an evaluation of therapies against leishmanial disease will be given.
