Projekt: ”Peripheral neuropathy in diabetes – methods for detecting large and small nerve fiber neuropathy”
Lokal: Handkirurgens bibliotek, Jan Waldenströms gata 5, Sus Malmö

Peripheral neuropathy is a frequent long-term complication in diabetes mellitus, affecting up to 50 % of all people with type 2 diabetes mellitus. It affects both myelinated and non-myelinated nerve fibers, among which small non-myelinated nerve fibers are reported to be the first to be affected. Dysfunction of nerve fibers can be evaluated by a number of methods but novel screening methods are needed. 

Vibration perception thresholds (VPTs), i.e. the lowest vibrational intensity possible to perceive at a particular frequency, are known to be impaired at an early stage in different neuropathies. However, normative values for VPTs investigated through multi-frequency vibrometry is lacking. Another novel method for investigation of small nerve fiber dysfunction is the assessment of intraepidermal nerve fiber density (IENFD) in skin biopsies. Normative values for IENFD are only available from smaller populations and for more complex methodologies. 

Aim and methods
The aim of this thesis is to constitute normative values of VPTs and IENFD, as well as to investigate the potential affecting factors. Additionally, it aims to investigate the clinical implication of both methods in patients with type 1 and 2 diabetes in order to achieve a greater knowledge on the effect of diabetes on the peripheral nervous system. 

Preliminary results
In paper I, I present a reference material of VPT values investigated through multi-frequency vibrometry in 913 healthy adults. The results suggest that VPTs are mainly affected by age, but also skin temperature and height influence VPTs to some extent. In paper IV, I investigated the temporal trend of IENFD in healthy people and patients with type 2 diabetes. IENFD was reduced over time for both groups and although healthy subjects had significantly higher levels at baseline, IENFD was equally low for the two groups at follow-up. These results indicate an earlier decline in IENFD in patients with diabetes but also a significant effect of ageing, regardless of health status. 

Since treatment for peripheral neuropathy is lacking, it is of great clinical importance to detect early changes of neuropathy and enable proactive care. Examination of VPTs or IENFDs are potential future diagnostic tools to be used in a clinical practice.

Handledare: Elin Trägårdh
Granskare: Sigrid Leige Svegborn, docent LU, och Anders Sundin, professor, Uppsala universitet



Patients with neuroendocrine tumors (NETs) do oftenhave metastasized disease at diagnosis, but the tumors can be indolent andpatients can survive for long. Quantification of tumors measured on positronemitting tomography – computed tomography (PET-CT) is of value both during thediagnostic work-up, during follow-up and when evaluating treatments. The overallaim of this thesis is to increase the knowledge about the uptake of 68Ga-DOTA-TATE/TOCin NETs and to develop an automatic method for quantification of NETs withartificial intelligence (AI). 

Aims and Methods
The aim of the first study was to evaluate iflong-acting somatostatin analog (LA-SSA) treatment changes the uptake of 68Ga-DOTA-TATEin patients with NETs. The effect of LA-SSA on 68Ga-DOTA-TATE uptakein tumors and normal liver tissue was evaluated in a clinical trial - Gapetto -designed as a prospective observational study. The aim of the second study wasto evaluate if total tumor burden manually segmented on PET-CT images, correlatedto health related quality of life (HRQoL), in a cohort of patients with metastasized gastroenteropancreaticNETs. Analysis of data is ongoing. The aim of the third study is to develop amethod with AI to detect and quantify tumor burden. Manual segmentations oftumors will be used for training of AI-networks and thereafter evaluated. This studyis ongoing. The aim of the fourth study is to evaluate the method developed inthe third study, this study has not started.

Preliminary results
No significantchanges were seen in the uptake in tumor lesions, but significant lower uptakein normal liver tissue after treatment initiation with LA-SSA. No significantcorrelations were found between total tumor burden and HRQoL.

Treatment with LA-SSA does not change the uptake intumor lesions, but decreases the uptake in normal liver tissue. These findings areimportant when interpreting 68Ga-DOTA-TATE PET-CT images and forguidelines regarding discontinuation of treatment before PET-CT scan. HRQoLdoes not seem to be correlated with the magnitude of the tumor burden, which isof importance when treating a patient. An automatic method for quantificationof tumors can save time when interpreting images and potentially provide moreinformation from the images.

Background and aims
Tuberculosis (TB) remains a major cause of death in people with HIV (PWH).Several circumstances are involved in this phenomenon, especially inefficient immuneresponses to TB infection and lack of effective screening methods for TBcase-finding in PWH. In this thesis, I aim to explore the role of smallnon-coding RNAs (sncRNA) in TB/HIV coinfection, and to investigate hostbiomarkers that may be used for TB screening in PWH.

These studies are mainly based on a cohort of 833 treatment naïve PWHrecruited and followed at Ethiopian health centres. Participants have beensystematically investigated for active TB, with collection of blood atinclusion and during follow-up. Persons with and without TB have been compared inrelation to concentrations of nine cytokines and acute-phase proteins in plasma,as well as kynurenine/tryptophan ratio. Moreover, longitudinal sncRNAexpression levels in blood have been compared in persons with TB with andwithout HIV coinfection.

- Levelsof most plasma inflammation markers analysed were higher in TB-coinfected PWH. Thebest performance for discriminating TB coinfection was achieved with acombination of the CRP and suPAR markers.

- Kynurenine/tryptophanratio was significantly increased in PWH with TB. However, compared to previousstudies, the performance of this ratio for TB case-finding was limited. 

- MicroRNAexpression was strongly altered and linked to HIV status in persons with TB,whereas small nucleolar RNA expression was downregulated in TB, regardless ofHIV status, compared to healthy controls. After initiation of treatment for TBand HIV normalization of sncRNA expression patterns towards the control groupwas noted.

The dysregulated sncRNA expression observed in TB/HIV coinfection suggesta role for this regulatory mechanism in the immune pathogenesis of TB in HIVinfection. Selected sncRNAs might also have potential as biomarkers for TB inPWH. Inflammatory mediators and kynurenine/tryptophan ratio may also be usefulfor this purpose.

Projekt: “The diabetic hand – epidemiology and pathophysiology of diabetic hand problems based on data from local and national registries in Sweden”
Lokal: Handkirurgens konferensrum plan 3, Jan Waldenströms gata 5, Skånes universitetssjukhus
Via Zoom: Uppdateras snart!
Huvudhandledare: Lars Dahlin

”The diabetic hand” includes diseases in the peripheral nerves and connective tissues in the upper extremity, ultimately resulting in diagnoses such as Carpal tunnel syndrome (CTS), ulnar nerve entrapment at the elbow (UNE), trigger finger (TF), Dupuytren’s disease (DD), and possibly also osteoarthritis (OA) of the first carpometacarpal (CMC-1) joint. However, both the incidence and the prevalence of these diagnoses are still unknown in the population with diabetes mellitus (DM). Furthermore, the pathophysiology most probably differs between type 1 diabetes (T1D), where hyperglycaemia is the main underlying factor, and type 2 diabetes (T2D), where hyperlipidaemia is a major contributor to the underlying pathophysiology. This might affect the appearance of hand complications included in the diabetic hand. 

The aim of this thesis is to increase our understanding of the diabetic hand – if and why the prevalence of hand disorders is more frequent in the population with DM and how to best treat these patients. 

By linking local, regional and national patient registers, the dissertation will result in the following projects with the following aims:

-  To calculate the prevalence and incidence of five common hand surgical diagnoses in the population with T1D and T2D in Region Skåne (I).

-  To identify metabolic risk factors associated with compression neuropathies in the upper extremity (II).

-  To identify the role of a high BMI for the development of OA of the CMC-1 joint. (III).

-  To identify metabolic risk factors for the development of DD (IV).

-  To explore surgical outcome after TF surgery among patients with T1D and T2D using patient reported outcome measurements (V).

-  To explore if strict blood sugar control effectively lowers the risk of TF among patients with T1D and T2D (VI) 

Preliminary results
CTS, UNE, TF, DD and OA of the CMC-1 joint are more prevalent among individuals with T1D and T2D. Furthermore, a high body mass index is associated with increased risk of the development of OA of the CMC-1 joint. Finally, DM is a major risk factor for both CTS and UNE. 

Through increased knowledge on how DM affects both the risk of development and the surgical outcome of the aforementioned diagnoses, the author hopes to shed lights on the diabetic hand, ultimately leading to better care of these patients.


High body mass index is associated with increased risk for osteoarthritis of the first carpometacarpal joint during more than 30 years of follow-up. Rydberg M, Dahlin LB, Gottsäter A, et al. RMD Open. 2020;6:e001368. doi: 10.1136/rmdopen-2020-001368

Prophylacticfactor VIII replacement therapy in Hemophilia A hasdrastically reduced the incidence of bleedings. However, bleedings still occur potentiallyresulting in arthropathy. Difference in FVIII pharmacokinetics and discrepancyin the assays (chromogenic and one-stage) used to measure FVIII levels caninfluence treatment results. Population-based pharmacokinetic (PK) can thushelp optimize treatment and reduce costs by individualizing the regimen to eachindividual patient, with the help of tools such as MyPKFiT and WAPPS-HEMO. Thechoice of FVIII product, degree of arthropathy, patient compliance anddifferent management practices of hemophilia centers can also influenceoutcomes. 

In study I, the PK estimations by MyPKFiT and WAPPS-Hemo were comparedand evaluated in the context of the patients´ clinical phenotype. In study II,treatment outcomes such as bleeding episodes, arthropathy, adherence totreatment and FVIII consumption were evaluated in patients treated at twoScandinavian Hemophilia centers prior and after the switch to treatment withthe recombinant FVIII product octocog alfa. 

Study I showed that MyPKFiT and WAPPS-HEMO yielded similar t½ despitesignificant assay discrepancy. However, there were significant differences inthe time to reach 1%, 3% and 5%. Accordingly, the doses estimated by WAPPS-Hemowere between 28% and 100% of those proposed by MyPKFiT. Study II showed thatthe study cohort had excellent adherence to treatment  and very low bleeding rates (medianannualized bleeding rate (ABR) and annualized joint bleed rate (AJBR) were both0) prior and after the switch to octocog alfa, despite a relatively high degreeof arthropathy. There was non-significant slightly lower mean ABR (0.7 vs 0.4)and AJBR (0.7 vs 0.3) after the switch. The mean annual factor consumption of octocogalfa was 3,862 IU/kg/year at the Malmö center and 2,337 IU/kg/year) at the Oslocentre (p=0.006), with slightly lower mean bleeding rate of 0.33 vs. 0.42. 

Population-based PK tools WAPPS-Hemo and MyPKFiTovercome assay discrepancy but WAPPS-HEMO produced lower dosing estimationsthan MyPKFiT which may impact treatment optimization. However, individualized prophylaxisregimens and excellent adherence to treatment can still achieve excellenthemostatic activity despite lower FVIII consumption.

Projekt: "Can breast cancer screening be improved with artificial intelligence?"
Via Zoom:
Handledare: Sophia Zackrisson
Bihandledare: Magnus Dustler och Anders Tingberg
Granskare: Sonja Aits, lektor Lunds universitet och Lars Edenbrandt, professor Göteborgs universitet



Screening for breast cancer with digital mammography (DM) is implemented in order to detect breast cancer earlier and reduce breast cancer mortality. Still, many breast cancer cases are diagnosed between screening occasions. Digital breast tomosynthesis (DBT) has been shown to be able to detect more cancer in screening, but requires longer reading time. Artificial intelligence might open new possibilities in screening, either by making reading faster or by increasing sensitivity. 

Materials and methods
Projects 1-4 are based on data collected in the Malmö Breast Tomosynthesis Screening Trial (MBTST), where almost 15000 women were examined with both DM and DBT at one screening occasion. In project 1 it is studied if an AI system can exclude normal cases from screen reading. Project 2 investigates the ability of the AI system to detect more cancers on DM, otherwise only detected with DBT, and if the AI system correctly localises cancers. In project 3 the AI system is used to analyse DBT examinations and a number of different ways of using AI to reduce the total reading time is evaluated. Project 4 will focus on if AI can detect more cancers in DBT. Project 5 involves building a database of DM examinations in order to test AI in a larger material. 

Preliminary results
Project 1 showed that AI can identify a proportion of examinations as free of cancer, thereby potentially reducing the reading burden as well as the number of false positives. In project 2 the AI system could detect almost half of the DBT-only screening-detected cancers in the MBTST based on DM data. Project 3 concluded that AI can exclude the half of cases with lowest risk of breast cancer from reading and still almost all cancers would be detected, while the number of false positives is reduced. Project 4 and 5 are still ongoing and no preliminary results are yet available. 

We have shown that AI can potentially improve breast cancer screening, either by detecting more cancers on DM (2), or by reducing reading time on DM and DBT (1 and 3), which can open possibilities to introduce new methods, e.g. DBT, in screening.

Projekt: "Tumor features in breast imaging - correlation to diagnosis and prognosis"
Via Zoom:

Granskare: Salma Butt, MD PhD och Sara Alkner, MD PhD



Breast imaging is fundamental in early detection, diagnosis, and follow-up in breast cancer. Mammography is the most used method, however ultrasound, digital breast tomosynthesis and magnetic resonance imaging (MRI) are also employed in clinical diagnostics. Apart from diagnostic information, radiological images harbor features that can aid in treatment choices and prognostication, although their full potential is not used in clinical practice. The aim of this thesis is to further investigate how imaging features relate to clinicopathological factors and survival in breast cancer, using both an epidemiological and an explorative approach.

Materials and methods
Project 1 – 3 uses data from the Malmö Diet and Cancer Study. Project 1 and 2 includes women diagnosed with invasive breast cancer 1991 – 2014 (n = 1116). Project 1 focuses on how mammographic tumor appearance is related to clinicopathological factors. Project 2 investigates whether tumor appearance and mammographic breast density impacts breast cancer specific survival. The detection mode, screening or clinically detected cancer, is considered in analyses. Project 3 includes a subset of spiculated tumors. Here, we develop a clinical mammography tool that can potentially pinpoint tumors with a favorable outcome. Project 4 is an explorative study using high field breast MRI, with the aim to better understand the tumor composition in relation to the surrounding breast tissue.

Preliminary results
Project 1 established that spiculated breast tumors tend to have favorable characteristics, such as positivity for estrogen receptor, progesterone receptor, lower Ki67 expression and lower histological grade. They are also more often of the Luminal A-like subtype, which carries a good prognosis. In project 2 no significant impact on breast cancer specific survival was seen for different tumors appearances, nor for breast density level. Projects 3 and 4 are ongoing, currently in data-collection phase.

We have investigated relations between imaging parameters and clinicopathological factors

(1) and patient outcomes (2), which we hope can extend the use of the radiological image in clinical practice. With novel analyses on an imaging tool and MRI we hope to further deepen imaging knowledge. This thesis aims to highlight and advance the central part of imaging in multidisciplinary breast cancer care, using different approaches.

Projekt: "PET-CT in prostate cancer: Study of protocol optimization, diagnostic performance and biokinetics"
Via Zoom:
Huvudhandledare: Elin Trägårdh
Granskare: Katarina Gleisner Sjögreen, Fredrik Liedberg



Positron emission tomography – computed tomography (PET-CT) is a hybrid imaging modality that combines a nuclear medicine technique (PET) with the ability to show the spatial distribution of metabolic or biochemical activity in the body fused with a CT to obtain anatomic images. Recently, a novel generation of PET-CT scanners, with digital Silicon photomultiplier (SiPM)-based technology was introduced. This digital PET-CT system is hoped to increase the diagnostic accuracy due to its high resolution.

The overall aim of the project is to evaluate the different aspects of PET-CT imaging in patients with prostate cancer: image reconstruction and optimization of digital PET-CT protocols for 18F-Choline , diagnostic accuracy for 18F-Choline using histopathology as reference method and biokinetics of a novel radiopharmaceutical: 18F-PSMA.

My research project is divided into four partial studies. The first study was an optimization study of a novel reconstruction algorithm of the new PET-CT system. In paper 2 the accuracy of detecting lymph node metastases using 18F-choline PET-CT was evaluated with lymph node dissection as reference method in a clinical context and the in paper 3 we wanted to examine whether the conventional PET-CT system are performing at the same level as the digital PET-CT system.  The aim of paper 4 is to understand the distribution of 18F-PSMA-1007 in the body at patients with prostate cancer and to calculate the absorbed dose for different organs and to the whole patient.

Paper 1 show that based on contrast to noise-ratio, CNR, and signal to noise-ratio, SNR, to use beta factor 400-550 with 1.5min/bed position or beta factor 300-550 with 2 min/bed position at 4MBq/kg 18F-Choline. Paper 2 states the poor performance of 18F-Choline PET-CT to predict lymph node metastases in prostate cancer. In paper 3 the conventional and digital PET-CT systems had similar overall diagnostic performance in detecting lymph node metastases but marked difference in sensitivity and specificity. For paper 4, data collection is in progress.

Project: "Dynamics of immune control of latent tuberculosis infection in relation to pregnancy"
Supervisor: Per Björkman, Lund University, Malmö
Co-Supervisors: Marianne Jansson, Erik Sturegård and Taye Tolera Balcha
Opponents: Susanna Brighenti and Oonagh Shannon 



Women infected with Mycobacterium tuberculosis (Mtb) have increased incidence of active tuberculosis (TB) in connection to pregnancy, with a particularly high risk in HIV co-infected individuals. The reason may be linked to the physiological immune modulation during pregnancy, which could disrupt the immune control of Mtb replication, and may consequently trigger reactivation of latent TB infection (LTBI). While the mechanisms involved cannot be explored at the pulmonary site of latent infection in humans, these phenomena may be reflected by patterns of immune mediators secreted during pregnancy and post-partum. Furthermore, this immune alternation could affect the performance of immune-based assays for LTBI diagnosis. The overall aim of this thesis is to investigate how pregnancy affects the immune control of LTBI.

This project is based on a prospective cohort of 2093 women recruited 2015-2018 during pregnancy, with follow-up post-partum in public health clinics in Adama, Ethiopia. Blood samples are collected at inclusion and at defined time points during pregnancy and post-partum for LTBI testing. This is performed by interferon-γ (IFN-γ) quantification after incubation with Mtb antigens using the QuantiFERON-TB Gold Plus assay (a new version of QFT; including two preparations [TB1 and TB2] of Mtb-specific antigens).

In study I, a cross-sectional analysis was performed to evaluate the performance of QFT-Plus assay from 829 pregnant women (49 HIV-positive) included during pregnancy. Two hundred seventy seven (33%) of these were QFT-positive using the recommended cut-off level 0.35 IU/ml, with high agreement between TB1 and TB2 antigens. QFT IFN-γ borderline results (defined as 0.20-0.70 IU/ml) were noted for a high proportion (29%) of HIV-positive women (compared to 7.6% among HIV-negative women), who also had significantly lower median IFN-g release compared to HIV-negative participants (TB1: 0.47 vs. 2.16 IU/ml; p<0.01, TB2: 0.49 vs. 2.24 IU/ ml; p<0.001).

In study II, we explored alternative cytokine markers in supernatants of whole blood stimulated with Mtb antigens, separately or in combinations to evaluate the LTBI status of pregnant women with QFT IFN-γ results in the borderline range. For this, we selected 96 pregnant women from the cohort based on QFT IFN-γ results, divided into three categories (QFT-low: <0.20 IU/ml, QFT- borderline: 0.20–0.70 IU/ml, QFT-high: >0.70 IU/ml), including 12 HIV-positive women in each group. Samples from HIV-negative women with QFT<0.20 IU/ml obtained >9 months after delivery were included as controls. We measured the concentration of eight markers (IL-1ra, IL-6, IL-8, IP-10, MCP-1, MCP-2, osteopontin and resistin) using Luminex assay. Classification analysis was performed using two different machine-learning algorithms to categorize participants with regard to their likelihood of having LTBI. The concentrations of MCP-2, IP-10 and IL-1ra in Mtb-antigen stimulated supernatants could distinguish women with IFN-γ borderline results. A combination of these three markers classified 42% of women with borderline results as having high likelihood of LTBI.  

In study III, we performed QFT testing on samples from women followed longitudinally during pregnancy (1st/2nd and 3rd trimesters) and post-partum to study the impact of pregnancy on the Mtb-triggered IFN-γ secretion. For this analysis, we chose a lower cut-off (IFN-γ≥0.20 IU/ml) to define QFT positive results, in order to account for reduced IFN-γ secretion during pregnancy. In total, 404 women (10% HIV-positive) sampled on two and/or three occasions had persistently positive QFT results. We observed that median IFN-γ secretion was elevated during the 3rd trimester compared to 1st/2nd trimester (TB1: 2.8 vs 1.6 IU/ml, p=0.01; TB2: 3.2 vs 2.7 IU/ml, p=0.05) and post-partum (TB1: 2.9 vs 2.2 IU/ml, p=0.009; TB2: 3.0 vs 2.16 IU/ml, p=0.04). Instead, mitogen-stimulated IFN-γ levels were lower at the 3rd trimester compared with the 1st/2nd trimester (8.0 vs 9.1, p=0.02).

In study IV, we hypothesise that analysis of additional immune mediators triggered by Mtb-antigen stimulation could provide more detailed information on how pregnancy affects the immune control of LTBI. For this study, additional immunological markers related to pregnancy and TB infection were screened in a pilot study. Four markers (IL-2, granzyme B, TGF-β1and MCP-3) from this pilot and three markers (IP-10, MCP-2, IL-1ra) from study II have been selected for the longitudinal analysis. Currently, we are performing the quantification of these immune mediators in QFT samples obtained longitudinally from women at different stages of pregnancy and post-partum. We estimate to complete the laboratory analysis at the end of this year.

Overall, these studies, based on Mtb antigen-stimulated whole blood from women living in a TB-endemic setting, suggest that analyzing alternative immune mediators, instead of repeated IFN-γ testing, is potentially a promising approach to assess LTBI status of pregnant women. The three biomarkers (IP-10, MCP-2 and IL-1ra) analysed in study II could distinguish women with IFN-γ borderline results, with similar performance in women with and without HIV infection. In the longitudinal analysis, elevated Mtb-specific IFN-γ secretion during later stages of pregnancy (despite reduced mitogen-triggered response) suggests increased immune cell exposure to Mtb antigens at later stages of pregnancy. We anticipate that analysis of a range of other immune mediators will provide further knowledge on how pregnancy affects immune control of LTBI.

Projekt: "A characterization of Hemophilia B – diagnostics and correlation between genotype, phenotype and clinical outcome"

Handledare: Jan Astermark, professor

Hemophilia B (HB), caused by the deficiency of coagulation factor IX (FIX), is an inherited X-linked bleeding disorder. Because of the rarity of the disease much of our knowledge and treatment recommendations for HB have been extrapolated from studies based on patients with the more common hemophilia A (HA). HA and HB have historically been seen as identical disorders but there are important differences between the diseases. The diagnosis and severity of hemophilia is based on the factor activity. Assay discrepancy in factor VIII activity between the one-stage and the chromogenic assays has been described in non-severe haemophilia A. Whether assay discrepancy may also occur in patients with hemophilia B is previously not known. The aim of this project was to bring a better understanding to hemophilia B, its phenotype, diagnostics and treatment, based on studies focusing on hemophilia B patients. 

In study I, plasma samples from patients with HB were collected and analyzed with both the one-stage and the chromogenic assays. Study II, a cross-sectional, retrospective study in the Nordic countries, gathered information on patients with severe HB to evaluate the treatment outcome and to compare this to a control group of patients with HA. Study III, an international, prospective, observational study included patients with all severities of HB to evaluate the phenotype within and between families. 

Preliminary results
Results from study I implies that assay discrepancy does occur for FIX activity and that this might be due to the underlying genotype. Study II showed a relatively high prevalence of FIX inhibitors of 14%. Lower Hemophilia Joint Health Scores among patients with HB compared to HA suggest that patients with severe HB suffer from a milder arthropathy than patients with severe HA. Study III has finished enrolment of 240 patients from 24 centres in Asia, Europe and North America and the dataset has been finalized. 

To be able to better understand the HB disease and to improve the care for our patients, studies focusing on the HB population are of importance. This is of even more significance today with new possibilities of individualized treatment.

Projekt: "Streptococcus pneumoniae – studies on the antipneumococcal immune response and epidemiology in Skåne and Angola"
Lokal: patologens föreläsningssal, Jan Waldenströms gata 59, Skånes universitetssjukhus Malmö
Handledare: Kristian Riesbeck, professor
Bihandledare: Jonas Ahl
Reviewers: Ander P Håkanson, professor, och Magnus Rasmussen, institutionen för kliniska vetenskaper i Lund



Streptococcus pneumoniae, the pneumococcus, is a colonizer of the human nasopharynx and a common aetiology of respiratory tract and systemic infections causing significant morbidity and mortality worldwide. Based upon the specific antibody response elicited by pneumococcal capsular polysaccharides, pneumococcal conjugate vaccines (PCVs) including 10-13 of the 100 known serotypes are used in infant immunization programmes. For vaccine evaluation purposes and due to the risk of emerging virulent or antibiotic resistant nonvaccine serotypes, surveillance of pneumococcal epidemiology is important. Furthermore, it is unknown to what extent an episode of pneumococcal infection results in functional adaptive immunity.

To characterize the spectrum of S. pneumoniae circulating related to PCV use in Skåne and Angola, pneumococci were isolated from clinical respiratory tract cultures and a nasopharyngeal carriage study was performed, respectively. Additionally, the spectrum of bacteria related to chronic suppurative otitis media in Angola was studied. Pneumococcal isolates were serotyped using a polymerase chain reaction scheme and antibiotic susceptibility patterns were determined. In parallel, the humoral immune response of patients with pneumococcal pneumonia and/or bacteraemia with different serotypes was assessed with an opsonophagocytic assay.

The introduction of PCV in Skåne resulted in a decreased proportion of PCV-included serotypes, from 45% in 2007-2008 to 17% in 2016-2018, although the vaccine-serotypes 3 and 19A were still prevalent in the nonvaccinated age group. In Angola, colonization with PCV-included serotypes was prevalent (14%) among PCV-unvaccinated children 4 years after the introduction of PCV, and these serotypes were associated with penicillin non-susceptibility (p=0.003). A nonfunctional opsonic antibody response was commonly observed (43%) after pneumococcal pneumonia and/or bacteraemia and was associated with low-invasive serotypes (p=0.015) and bacteraemia (p=0.019).

Continued occurrence of PCV-serotypes among certain age groups in Skåne may indicate limitations of PCV herd effects regarding certain serotypes. A first description on pneumococcal epidemiology in Angola is reported, providing baseline data for future studies. Studies of the immune response induced by exposure to S. pneumoniae are scarce but may improve our understanding of the human immune system and possibly have implications for future vaccine strategies.

Projekt: "The HIV–1 epidemic in Ethiopia – transmission patterns, antiretroviral drug resistance and treatment outcomes" 
Lokal: Segerfalksalen, BMC, Sölvegatan 19, Lund

Human immunodeficiencyvirus type 1 (HIV-1) is characterised by extensive genetic heterogeneity thathas implications for diagnosis, vaccine development, and clinical management ofHIV infection. Previous studies have shown that subtype C is dominant inEthiopia although a detailed survey of subtypes and CRFs has not been performedrecently. A nation-wide monitoring of the HIV epidemic, through geneticcharacterization of HIV drug resistance prevalence and the dynamics of themolecular epidemiology will be instrumental for designing new public healthpolicies, which will be important in prevention and treatment interventions. 

The expansion ofantiretroviral therapy (ART) has markedly reduced HIV-related morbidity,mortality, and transmission. However, the emergence and transmission of HIVdrug resistance (HIVDR) constitutes a threat to the outcome of treatmentprograms and is an imminent obstacle for the planned elimination of HIV as apublic health threat. In Ethiopia, there is limited information on theprevalence of HIVDR (acquired and transmitted). Thus, there is a need todetermine the magnitude of the problem of HIVDR among general population andhigh-risk group (female sex workers). 


1. To determine the prevalence ofHIVDR before ART initiation and during ART in patients receiving care both inhealth centres and hospital

2. To characterize the subtypedistribution and the spread of HIV-1 in Ethiopia by virological geneticanalyses, including studies of the epidemic in and between different regions ofEthiopia, along major highways in Ethiopia, and among groups with differentrisk profiles 

Study questions

1. What are the major HIV-1subtype (sub-subtype) circulating in Ethiopia? When and how the HIV-1 epidemicspread in Ethiopia?

2. What is the prevalence of HIVDRamong recently infected, chronically infected and patient on ART? What is theimplication on this on treatment program?

3. Are female sex workers at highrisk for the emergency of and transmission of HIVDR to the general population?

4. Are female sex workers drivingthe HIV epidemic in Ethiopia? 

Our molecularepidemiology result will provide information on dynamics of the HIV1 epidemicin Ethiopia that are crucial for effective treatment strategies, as well as forthe planning of medical interventions and for the design of effectiveprevention programs targeting both the general population and most at riskpopulations. The HIV drug resistance information from the different study groupwill be very important for the strengthening the national ART program forEthiopia and other countries with similar situation.

Projekt: “The emerging pathogen Haemophilus Influenzae - host/pathogen interactions"
Lokal: patologens föreläsningssal, Jan Waldenströms gata 59, Skånes universitetssjukhus Malmö
Handledare: prof. Kristian Riesbeck
Bihandledare: prof. Karin Leandersson och med. dr. Farshid Jalalvand
Examinatorer: prof. Ann Hermansson och med. dr. Erik Senneby



Non-typeable Haemophilus influenzae (NTHi) is a pathogen that commonly colonizes the na-sopharynx of preschool children, causing opportunistic infections including acute otitis me-dia (AOM). Patients suffering from chronic obstructive pulmonary disease (COPD) are per-sistently colonized with NTHi and occasionally suffer from exacerbations by the bacterium leading to increased morbidity. Elongation-factor thermo unstable (EF-Tu), a protein critical for bacterial protein synthesis, has been found to “moonlight” on the bacterial surface where it is involved in the interaction with the host. 

Research question
The overall aim of my PhD project is to study the host-pathogen interaction of NTHi, with focus on EF-Tu and outer membrane protein P5. 

In paper 1 we show that EF-Tu from NTHi is surface exposed and recognized by antibodies mediating host innate immunity against NTHi. We could also observe a prominent cross-reaction with other unencapsulated respiratory tract bacteria.1 

In paper 2 we found that antibodies against NTHi EF-Tu were present in children al-ready at 18 months of age, and that the IgG antibody titers increased with age. Children harboring NTHi in the nasopharynx displayed significantly higher IgG concentrations and children suffering from AOM had significantly higher anti-EF-Tu IgG levels when NTHi was the causative agent. Finally, we demonstrated that immunization of BALB/c and otitis-prone Junbo (C3H/HeH) mice with recombinant EF-Tu promoted lower infection rates in the nasopharynx and middle ear, respectively.2
