- The purpose of this study was to elucidate conditions at all system levels in a specific health care service to develop practices for identification of children as relatives. An interactive research approach with the intention to create mutual learning between practice and research was used. The participating health care service cared for both clinic in- and outpatients with psychiatric disorders. Health care professionals from different system levels (micro, meso, macro) participated, representing different professions. At the first project meeting, it was obvious that there was no systematic approach to identify children as relatives. At the micro level, activities such as a pilot survey and an open house activity were carried out. At the meso level, it was discussed how to better support collaboration between units. At the management (macro) level, it was decided that all units should appoint at least one child agent, with the aim to increase collaboration throughout the whole health care service. To change focus, in this case from only parents to inclusion of children, is an important challenge faced by health care services when forced to incorporate new policies and regulations. The new regulations contribute to increased complexity in already complex organizations. This study highlights that such challenges are underestimated.

- Breakthrough Collaborative (BC) aims at learning through networking, mainly at micro level, and is used as a tool to improve care and welfare organizations. The aim of this study was to explore and illuminate the challenges when applying BC model at meso and macro level. In 2010, the Swedish Health and Medical Services Act stated the responsibility of healthcare professionals to consider children’s needs as relatives. This study uses an interactive collaborative research model. To support healthcare organizations in the implementation of the regulation, county councils/regions in Sweden were invited to take part in a BC during 2015. Six teams from different county councils/regions participated. Team members were interviewed several times during the project time. Data were analyzed with an explorative and descriptive qualitative content analysis. The result illuminates the challenges faced when applying BC at meso and macro level. Most challenges concern preparation, support structures and system connections. There are similarities with the challenges met at micro level when BC is used at meso and macro level. But it seems even more important to consider how the team is constituted at meso and macro level to make use of the learnings and achieve long-term impact in the home organization.

- Solid organ transplant recipients (SOTRs) are on lifelong immunosuppression, which may interfere with adaptive immunity to COVID-19. The data on dynamics and duration of antibody response in SOTRs are limited. This longitudinal study examined the longevity of both anti-spike (S)- and anti-nucleocapsid (N)-specific IgG-antibodies after COVID-19 in SOTRs compared to matched immunocompetent persons. SOTRs (n=65) were matched with controls (n=65) for COVID-19 disease severity, age, and sex in order of priority. Serum-IgG-antibodies against N- and S-antigens of SARS-CoV-2 were analyzed. At 1 and 9 months after COVID-19, anti-S-IgG detectability decreased from 91% to 82% in SOTRs versus 100% to 95% in controls, whereas the anti-N-IgG decreased from 63% to 29% in SOTRs versus 89% to 46% in controls. A matched paired analysis showed SOTRs having significantly lower levels of anti-N-IgG at all time points (1-month P=0.007, 3-months P<0.001, 6-months P=0.019 and 9-months P=0.021) but not anti-S-IgG at any time points. A mixed-model analysis confirmed these findings except for anti-S-IgG at one month (p=0.005) and identified severity score as the most important predictor of antibody response. SOTRs mount comparable S-specific, but not N-specific, antibody responses to SARS-CoV-2 infection compared to immunocompetent controls.

Immunopathogenesis of relapsing fever borreliosis
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Relapsing fever (RF) is caused by different species of Borrelia transmitted by soft ticks or by the human body louse. Illness is characterized by reappearing peaks of high concentrations of spirochetes in blood, concordant with fever peaks separated by asymptomatic periods. Neuroborreliosis is one of the most severe manifestations of RF borreliosis. To understand the immune response during early RF, we analyzed immune cells in brain and kidney of mice infected with B. crocidurae during the acute infection. Our results indicate that brain defense is comprised primarily of innate immune cells. Despite the infiltration of innate immune cells, Borrelia was not completely eradicated. A failure of the host brain to clear the bacteria may give the pathogen a niche where it can persist. Using our mouse model, we revealed that Borrelia duttonii could persist in the mouse brain for up to 270 days, without being present in the circulation. The infection was silent with no change in host gene expression, and the spirochetes could re-enter the circulation after immunosuppression. We propose that the brain is used by the pathogen to evade host immunity and serves as a possible natural reservoir for B. duttonii, a spirochete that has rarely been found in any mammalian host other than man. Borrelia-induced complications during pregnancy have been reported, and are especially common in RF. In our established mouse model of gestational RF, we could show that the fetuses suffered from severe pathology and growth retardation, probably as a consequence of placental destruction. We could also show trans-placental transmission of the bacteria leading to neonatal RF. Surprisingly, pregnant dams had a lower bacterial load and less severe disease, showing that pregnancy has a protective effect during RF. We have used the gestational RF model to investigate host factors favoring disease resolution. Because the spleen is the primary organ responsible for trapping and removing blood-borne pathogens, we have compared temporal changes in spleen immune cell populations and cytokine/chemokine induction during the infection. Spleens of pregnant mice had earlier neutrophil infiltration, as well as faster and higher production of pro-inflammatory mediators. This rapid, robust response suggests a more effective host defense. Thus, an enhanced pro-inflammatory response during pregnancy imparts a distinct advantage in controlling the severity of relapsing fever infection.

- Post-transplantation lymphoproliferative is a potentially mortal complication after heart transplantation in children. As the immune system plays a crucial role in the development of lymphoma, we explored the influence of thymus function in relation to immunosuppressive treatment in organ-transplanted children and healthy control subjects. A prospective case-control study was performed at a single centre, in which 36 children who had undergone heart transplantation were compared to two control groups: 34 kidney-transplanted children and 33 healthy age- and sex-matched children. T- and B-lymphocyte subtypes and monocytes were analysed by flow cytometry, and T-cell receptor excision circles were assessed using quantitative polymerase chain reaction. Heart-transplanted children had a lymphocyte profile characterised by reduced or absent thymic function with low numbers of T-cell receptor excision circles and total and naïve T cells, together with immune activation against the allograft. Despite similar immunosuppressive treatment, the kidney-transplanted group showed an activated T-lymphocyte compartment.
