People with HIV continue to experience HIV stigma. Quantitative data on HIV stigma perpetrated by healthcare providers of hospitals providing HIV care in high-income countries are limited. The aim of this study is to investigate factors associated with HIV stigma in Dutch healthcare settings from the healthcare providers’ perspective. We conducted a cross-sectional study using the questionnaire ‘Measuring HIV Stigma and Discrimination Among Health Facility Staff – Monitoring Tool for Global Indicators’ to assess HIV stigma among healthcare providers (n = 405) in two academic hospitals. Healthcare providers licensed to provide medical care were eligible for inclusion. The primary outcome was the self-reported prevalence of at least one manifestation of HIV stigma measured by six stigma indicators (four individual, two institutional). Secondary outcomes were the prevalence of HIV stigma per indicator, per occupation, per department, and factors associated with individual stigma indicators. HIV stigma was prevalent among 88.1% (95%CI 84.5% − 91.2%) of participants. Stigma was mostly driven by negative attitudes towards people with HIV and worry to acquire HIV. Multivariate analysis showed that several factors were associated with HIV stigma, including younger age, male sex, working at one of the surgical departments, and working as a nurse. Having received any training on HIV stigma and/or discrimination was associated with less HIV stigma among all indicators. In conclusion, HIV stigma is highly prevalent among Dutch healthcare providers. Targeted approaches, including training on HIV stigma and discrimination, are needed to reduce HIV stigma in healthcare and should, among others, focus on younger healthcare providers.

Background: Lymphocytopenia has frequently been described in patients with malaria, but studies on its association with disease severity have yielded conflicting results. The neutrophil/lymphocyte count ratio (NLCR) has been introduced as a parameter for systemic inflammation in critically ill patients and was found, together with lymphocytopenia, to be a better predictor of bacteraemia than routine parameters like C-reactive protein and total leukocyte count. In the present study, the predictive value of the NLCR and lymphocytopenia for severe disease was evaluated in patients with imported malaria. Methods. All patients diagnosed with malaria at the Harbour Hospital between January 1§ssup§st§esup§ 1999 and January 1§ssup§st§esup§ 2012 with differential white cell counts determined within the first 24 hours after admission were included in this retrospective study. Severe malaria was defined according to the WHO criteria. The performance of the NLCR and lymphocytopenia as a marker of severe malarial disease was compared back-to-back with that of C-reactive protein as a reference biomarker. Results: A total of 440 patients (severe falciparum malaria n = 61, non-severe falciparum malaria n = 259, non-falciparum malaria n=120) were included in the study. Lymphocytopenia was present in 52% of all patients and the median NLCR of all patients was 3.2. Total lymphocyte counts and NLCR did not differ significantly between groups. A significant correlation of total leukocyte count and NLCR, but not lymphocyte count, with parasitaemia was found. ROC analysis revealed a good negative predictive value but a poor positive predictive value of both lymphocytopenia and NLCR and performance was inferior to that of C-reactive protein. After complete parasite clearance a significant rise in total leukocyte count and lymphocyte count and a significant decrease in NLCR was observed. Conclusion: The NLCR was found to correlate with parasitaemia, but bo

Background: In Plasmodium falciparum infection, peripheral parasite counts do not always correlate well with the sequestered parasite burden. As erythrocytes parasitized with mature trophozoites and schizonts have a high tendency to adhere to the microvascular endothelium, they are often absent in peripheral blood samples. The appearance of schizonts in peripheral blood smears is thought to be a marker of high sequestered parasite burden and severe disease. In the present study, the value of schizontaemia as an early marker for severe disease in non-immune individuals with imported malaria was evaluated. Methods. All patients in the Rotterdam Malaria Cohort diagnosed with P. falciparum malaria between 1 January 1999 and 1 January 2012 were included. Thick and thin blood films were examined for the presence of schizontaemia. The occurrence of WHO defined severe malaria was the primary endpoint. The diagnostic performance of schizontaemia was compared with previously evaluated biomarkers C-reactive protein and lactate. Results: Schizonts were present on admission in 49 of 401 (12.2%) patients. Patients with schizontaemia were more likely to present with severe malaria, a more complicated course and had longer duration of admission in hospital. Schizontaemia had a specificity of 0.95, a sensitivity of 0.53, a negative predictive value of 0.92 and a positive predictive value of 0.67 for severe malaria. The presence of schizonts was an independent predictor for severe malaria. Conclusion: Absence of schizonts was found to be a specific marker for exclusion of severe malaria. Presence of schizonts on admission was associated with a high positive predictive value for severe malaria. This may be of help to identify patients who are at risk of a more severe course than would be expected when considering peripheral parasitaemia alone.
