Visceral leishmaniasis (VL) is a lethal disease if left untreated. Current treatments produce variable rates of treatment failure and toxicity without sterile cure, rendering treatment efficacy monitoring essential. To avoid repeated invasive tissue aspirates as well as empirical treatment, there is a need for new tools that allow a less-invasive and early assessment of treatment efficacy in the field. Cross-sectional studies have suggested levels of cytokines/chemokines after whole blood stimulation as good markers of cure, but longitudinal studies are lacking. In this study, we followed 13 active VL cases in an endemic area in Ethiopia by measuring the production of IFN-γ, TNF-α, IP-10, IL-2, IL-10, MCP-1, and MIG before, during, and at the end of treatment. After 24 hours of stimulation of whole blood with soluble Leishmania antigen, we observed an early, robust, and incremental increase of IFN-γ, TNF-α, and IP-10 levels in all patients during treatment. Moreover, based on the IFN-γ levels that showed an average 13-fold increase from the time of diagnosis until the end of treatment, we could almost perfectly discriminate active from cured status. Similar concentrations and patterns were found in stimulation assays with the two main Leishmania species. The levels of IFN-γ, IP-10, or TNF-α also seemed to be inversely associated with the parasite load at baseline. Despite a 1/10 drop in concentrations, similar patterns were observed in IFN-γ and IP-10 levels when dried plasma spots were stored at 4°C for an average of 225 days. All the above evidence suggests a detectable restoration of cell-mediated immunity in VL and its association with parasite clearance. With a potential application in rural settings by means of dried plasma spots, we recommend to further explore the early diagnostic value of such assays for treatment efficacy monitoring in large cohort studies including treatment failure cases.

SummaryBackground. Recombinant hirudin (RH) is a new anticoagulant for prophylaxis and treatment of venous and arterial thrombosis. To which extent the activated partial thromboplastin time (APTT) is suitable for monitoring of RH has not been properly evaluated. Recently, a capillary whole blood device was developed for bed-side monitoring of the APTT and it was demonstrated that this device was suitable to monitor heparin therapy. However, monitoring of RH was not evaluated.Study Objectives. To evaluate in vitro and ex vivo the responsiveness and reproducibility for hirudin monitoring of the whole blood monitor and of plasma APTT assays, which were performed with several reagents and two conventional coagulometers.Results. Large interindividual differences in hirudin responsiveness were noted in both the in vitro and the ex vivo experiments. The relationship between the APTT, expressed as clotting time or ratio of initial and prolonged APTT, and the hirudin concentration was nonlinear. A 1.5-fold increase of the clotting times was obtained at 150-200 ng/ml plasma. However, only a 2-fold increase was obtained at hirudin levels varying from 300 ng to more than 750 ng RH/ml plasma regardless of the assays. The relationship linearized upon logarithmic conversion of the ratio and the hirudin concentration. Disregarding the interindividual differences, and presuming full linearity of the relationship, all combinations were equally responsive to hirudin.Conclusions. All assays were equally responsive to hirudin. Levels up to 300 ng/ml plasma can be reliably estimated with each assay. The manual device may be preferable in situations where rapid availability of test results is necessary.

From last few years, the pervasiveness of diabetes mellitus (DM), in Saudi Arabia, is growing at a frightening rate. Overall, one-fourth of the adult population is affected by DM, which is further predicted to rise to more than double by the year 2030. The most alarming is possibly the escalation propensity of diabetes, in recent years, where a nearly ten-fold increase has been witnessed over the past thirty years in Saudi Arabia. However, the number of research arbitrations on the prevalence and incidence of DM is woefully inadequate, as compared to developed countries. Apart from this, most of the existing research data carried out in Saudi Arabia is cross-sectional, with small sample sizes, which most often involve only certain parts of the country. Consequently, the present scenario demands more multidimensional and multisectoral research to strengthen the evidence base and to accumulate greater knowledge as a basis for measures and programmes to confront diabetes and its complications. Thus, the present report makes an attempt to depict the current trend of diabetes as well as intends to put forward essential measures for controlling diabetes in Saudi Arabia.

Background: Alterations in gene expression in the peripheral blood of patients with acute stroke have been demonstrated using microarray technology. Whole blood and peripheral blood mononuclear cells (PBMCs) were used in prior studies in which panels of genes diagnostic for stroke were developed. We aimed to determine the cellular sources of alterations in gene expression by studying individual leukocyte subsets. Methods: The expression of four genes previously found to be upregulated in ischemic and hemorrhagic stroke (IL1R2, S100A9, ETS2 and F5) was measured in four leukocyte subsets: CD14+ monocytes, CD4+ T cell lymphocytes, CD20+ B cell lymphocytes and PBMCs. These four genes had been reported in at least two of the previously published stroke-related gene panels. Peripheral blood was obtained from six acute stroke patients (all <48 hours from symptom onset) and 6 age, race and sex matched control subjects. Leukocytes were separated from whole blood using density gradient centrifugation and column magnetic bead cell sorting. The purity of separated leukocyte subsets exceeded 90% and was verified with flow cytometry. Messenger RNA was isolated from each leukocyte subset and analyzed by two step RT PCR and qPCR. The expression of the four stroke-related genes was compared to the expression of a housekeeping gene (GAPDH). The relative expression of individual genes and of the 4 gene panel within cellular subsets was compared between stroke patients and control subjects. Results: Individually, IL1R2 and S100A9 were significantly over-expressed in stroke patients with a 10 fold increase for IL1R2 in PBMCs (p<0.05) and a 3 fold increase for S100A9 in the CD4+ T and CD20+ B lymphocyte subsets (p<0.05). When analyzed as a panel of four genes the expression of IL1R2, S100A9, ETS2 and F5 was significantly higher in both the CD4+ T lymphocytes (p<0.05) and CD20+ B lymphocytes (p<0.05) of stroke patients but not in the monocytes or the PBMCs. Conclusion: These results show the potential diagnostic value of selected genes from panels previously found in microarray studies in stroke patients. They also emphasize the value of panel analysis over that of single gene expression and the potential cellular specificity of alterations in gene expression. Analysis of whole blood and PBMCs alone may not reflect important dynamic changes in stroke-related gene expression.

BACKGROUND The use of Routine Outcome Monitoring (ROM) in the treatment of mental health has emerged as a method of improving psychotherapy treatment outcomes. Despite this, very few clinicians regularly use ROM in clinical practice. Online ROM has been suggested as a solution to increase adoption. OBJECTIVE To identify the influence of moving ROM online on client completion rates of self-reported outcome measures and to identify implementation and utilization barriers to online ROM by assessing clinicians’ views on their experience utilizing the online system over previous paper-based methods. METHODS Client completion rates of self-reported outcome measures were compared pre and post implementation of an online system of ROM. In addition, a survey questionnaire was administered to 340 mental health service providers regarding their perception of benefits with an online system of ROM. RESULTS Client completion rates of self-reported measures increased from 15% to 54% after moving online. Fifty-eight% of service providers found the new system less time consuming than previous paper-based ROM and 64% found that it helped monitor clients. However, the perceived value of the system remains in doubt as only 23% found it helped them identify clients at risk for treatment failure, and only 18% found it strengthened the therapeutic alliance. CONCLUSIONS Although the current study suggests mixed results regarding service providers’ views on their experience using an online system for ROM, it has identified barriers and challenges that are actionable for improvement.

Analysis of tissue lesions of the major reactional states of leprosy was undertaken to study the immune mechanisms underlying regulation of cell-mediated immunity and delayed-type hypersensitivity (DTH) in man. In situ hybridization hybridization of reversal reaction biopsy specimens for INF-gamma mRNA expression revealed a 10-fold increase in specific mRNA-containing cells over that observed in unresponsive lepromatous patients. Expression of huHF serine esterase, a marker for T cytotoxic cells, were fourfold increased in reversal reaction and tuberculoid lesions above that detected in unresponsive lepromatous individuals. Immunohistology of reversal reactions confirmed a selective increase of Th and T cytotoxic cells in the cellular immune response. Of interest, the microanatomic location of these serine esterase mRNA-containing cells was identical to the distribution of CD4+ cells. Analysis of erythema nodosum leprosum (ENL) lesions revealed differences in the underlying immune processes in comparison with reversal reaction lesions. Although phenotypic Th cells predominated in ENL lesions, IFN-gamma and serine esterase gene expression were markedly reduced. We suggest that reversal reactions represent a hyperimmune DTH response characterized by a selective increase of CD4+ IFN-gamma producing cells and T cytotoxic cells, which result in the clearing of bacilli and concomitant tissue damage. In contrast, ENL reactions may be viewed as a transient diminution of Ts cells and activity leading to a partial and transient augmentation in cell-mediated immunity, perhaps sufficient to result in antibody and immune complex formation, but insufficient to clear bacilli from lesions.

Abstract Background: The implications of congenital Zika Virus (ZIKV) infections for pediatric neurodevelopment and behavior remain inadequately studied. The aim of this study is to investigate patterns of neurodevelopment and behavior in children with different levels of ZIKV-related microcephaly or with prenatal ZIKV exposure in the absence of microcephaly. Methods: We conducted a cross-sectional study, nested in a cohort, of 274 children (aged 10-45 months) who were born during the peak and decline of the microcephaly epidemic in Northeast Brazil. Participants were evaluated between February 2017 and August 2019 at two tertiary care hospitals in Recife, Brazil. We analyzed the children in four groups assigned based on clinical and laboratory criteria: Group 1 had severe microcephaly; Group 2 had moderate microcephaly; Group 3 had prenatal ZIKVxposure confirmed by maternal RT-PCR testing and no microcephaly; and Group 4 was a neurotypical control group. Groups were evaluated clinically for neurological abnormalities and compared using the Survey of Wellbeing of Young Children (SWYC), a neurodevelopment and behavior screening instrument, and a SWYC adapted form to compare severe cases. Results: Based on the SWYC screening, we observed differences between the groups for developmental milestones but not behavior. Among children with severe microcephaly of whom 98.2% presented with neurological abnormalities, 99.1% were at risk of development delay, and presented similar performance whether evaluated under or over 24 months of age. Among children with moderate microcephaly of whom 60% presented with neurological abnormalities, 65% were at risk of development delay. For children without microcephaly, the percentages found to be at risk of developmental delays were markedly lower and did not differ by prenatal ZIKV exposure status: Groups 3, 13.8%; Group 4, 21.7%. Conclusions: Among groups of children with prenatal ZIKV exposure, we found a gradient of risk of development delay. Children with severe microcephaly were at highest risk, while normocephalic ZIKV-exposed children had similar risks to unexposed control children. We propose that ZIKV-exposed children should undergo first-line screening for neurodevelopment and behavior using the SWYC. Early assessment and follow-up will enable at-risk children to be referred to a more comprehensive developmental evaluation and to multidisciplinary care management.
