- In a previous population-based study on 3369 European men with self-reported prostate cancer (PCa), it was shown that androgen receptor (AR) haplotype designated H2 was associated with high levels of serum PSA (prostate-specific antigen) concentration, and, at the same time, with low risk for PCa. The aim of this study was to replicate this finding in other cohorts, with registry-based cancer diagnosis. Using data from two population-based cohorts; the Malmo Diet and Cancer Study (MDCS, n = 12,121) and the Swedish Osteoporotic fractures in men study (MrOS, n = 1,120), 628 men with PCa and 1,374 controls were identified and genotyped. PCa data were collected from the Swedish national cancer registry. PCa odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for carriers of the particular AR haplotype, tagged by the rs6624304 T-allele. The 15% of men who were carriers of the AR haplotype H2 had approximately one-third lower risk for PCa diagnosis compared to those with the most common H1 variant (OR 0.65; 95% CI 0.45-0.94; p = 0.021). The same trend, although not statistically significant (OR 0.75; 95% CI 0.47-1.24; p = 0.275), was observed in MrOS Sweden. When both cohorts were merged, an even more significant result was observed (OR 0.68; 95% CI 0.51-0.90; p = 0.008). Swedish men with the variant AR haplotype H2, tagged by rs6624304, have significantly lower risk of PCa compared to those with the more common variant.

- Purpose: We tested the hypothesis that low vitamin D is associated with benign prostatic hyperplasia. We also studied whether body composition, sex hormones, serum sex hormone-binding globulin, albumin corrected serum calcium, adiponectin and lipid status are associated with benign prostatic hyperplasia. Materials and Methods: We investigated 184 representative, randomly selected men 72 to 76 years old enrolled in the Gothenburg arm of the Osteoporotic Fractures in Men Study (MrOS). Men with a history of prostate cancer, prostate operation or medication for benign prostatic hyperplasia were excluded from study, leaving 155 available for analysis. A cross-sectional study was performed in which benign prostatic hyperplasia measured by total prostate volume was related to clinical, anthropometric, endocrine and metabolic factors on univariate and multivariate analyses with regression models. Results: Median prostate volume was 40 ml. In multivariate models only 25-OH vitamin D, albumin corrected serum calcium, serum sex hormone-binding globulin and high density lipoprotein cholesterol were significantly and inversely associated with large prostate glands. Conclusions: The current report adds 4 independent factors associated with benign prostatic hyperplasia, including low 25-OH vitamin D, serum calcium, sex hormone-binding globulin and high density lipoprotein cholesterol.

- PURPOSE: To test the hypothesis that low levels of vitamin D were associated with Benign Prostatic Enlargement (BPE). We also studied whether body composition, sex hormones, serum SHBG, albumin corrected serum calcium, adiponectin and lipid statuses were associated with BPE. MATERIALS AND METHODS: 184 representative randomly selected men aged 72 - 76 years, enrolled in the Gothenburg arm of the MrOs study, were investigated. Men with a medical history of prostate cancer, prostate operation or medication for BPE were excluded leaving 155 men to be analyzed. A cross-sectional study was conducted in which BPE, as measured by the total prostate gland volume, was related to clinical, anthropometric, endocrine and metabolic factors, using univariate and multivariate analyses with regression models. RESULTS: The median prostate volume was 40 ml. In multivariate models only 25-OH vitamin D, albumin corrected serum calcium, serum SHBG and HDL-cholesterol were significantly and inversely associated with large prostate glands. CONCLUSION: The present report adds four independent factors associated with BPE: Low levels of 25-OH vitamin D, serum calcium, SHBG and HDL-cholesterol.

- Abstract Objective. The aim of this study was to test whether lower urinary tract symptoms (LUTS) and urinary incontinence are associated with the metabolic syndrome (MetS). The association between LUTS and benign prostatic enlargement (BPE) was also investigated. Material and methods. A cross-sectional, representative risk factor analysis of LUTS, as measured by the International Prostate Symptom Score (IPSS), and urinary incontinence was conducted. Among 950 representative individuals, aged 69-81 years, the association between clinical, anthropometric, endocrine, metabolic and inflammatory factors on the one hand, as both major and minor aspects of MetS, and LUTS and urinary incontinence, on the other hand, was analysed. The prostate gland volume was measured in a subgroup of 155 randomly selected individuals and the association between LUTS and BPE was estimated. Results. No significant association was found between LUTS or urinary incontinence and the major aspects of the MetS. However, in a multivariate analysis, serum serotonin showed an independent negative correlation with LUTS and with urinary incontinence while fasting serum glucose and serum adiponectin showed a positive correlation with LUTS. Furthermore, in a subgroup of 155 individuals, the prostate gland volume correlated positively with LUTS. Conclusions. The study did not show an association between LUTS or urinary incontinence and the major components of the MetS. However, serum serotonin showed an independent negative correlation with LUTS and with urinary incontinence while fasting serum glucose and serum adiponectin showed a positive correlation with LUTS. The data confirm the general knowledge that BPE may be one of the causative factors of LUTS.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- ABSTRACT The overall aim of this thesis was to explore the association between the components of the metabolic syndrome (MetS), including vitamin D, and lower urinary tract symptoms (LUTS). The focus was on the relationship between diseases of the prostate, mainly benign prostatic enlargement (BPE) and prostate cancer (PC). The study cohort consisted of 3,014 Swedish men aged 69-81 enrolled in the Swedish arm of the Osteoporotic Fractures in men (MrOs) study. The study participants were randomly selected using population registries and then contacted and asked to participate in the study. The selected men were asked to fill in questionnaires regarding a variety of items such as daily activities and physical exercise, eating-, drinking- and smoking habits, medication, past and present history of diseases, voiding habits, surgery and current treatment. They underwent investigations regarding bone mineral density, measurements of body composition such as height, weight, body mass index, body fat mass and lean mass and blood samples were obtained for analyses of a variety of variables. In a subgroup of this cohort (1,010 individuals) more extended analyses were performed. Furthermore, in a small cohort (184 individuals), the prostate gland volumes were measured through transrectal ultrasonography. Lower urinary tract symptoms were measured by the International Prostate Symptom Score and urinary incontinence (UI) was evaluated by a questionnaire. The cohort has been followed for more than 10 years. The MrOs register was coordinated with the Swedish Death Register, the Swedish Cancer Register, and the National Prostate Cancer Register. This investigation showed that LUTS and UI were neither associated with any major component of the MetS, nor associated with serum levels of vitamin D. However, serum levels of serotonin were negatively associated with LUTS and UI, while fasting glucose and adiponectin were positively associated with LUTS. Benign prostatic enlargement was associated with low levels of vitamin D, serum calcium, sex hormone- binding globulin and high-density lipoprotein cholesterol. Individuals with type 2 Diabetes mellitus (T2DM) had a decreased risk of being diagnosed with incident prostate cancer. Increased levels of vitamin D were associated with increased risk of being diagnosed with PC. Individuals with low serum c-reactive-protein levels and taller individuals had a higher risk of developing PC. Plasma levels of osteocalcin, a protein produced by osteoblasts, were lower in individuals with T2DM, and higher in individuals with incident PC. The overall conclusions in the present thesis were that vitamin D was negatively associated with BPE and positively associated with PC, however, not associated with LUTS. In addition, the end-point component of MetS, T2DM, was positively associated with BPE but inversely associated with incident PC, and finally, that osteocalcin was positively associated with incident PC. Keywords: Metabolic syndrome, lower urinary tract symptoms, urinary incontinence, benign prostatic enlargement, prostate cancer, serotonin, vitamin D, osteocalcin

Forskningsöversikt (refereegranskat)abstract
- Metabolic syndrome is associated with increased cancer risk and progression at almost all sites, including the prostate in high-stage prostate cancer. However, several reports have described an inverse relationship between metabolic syndrome and its components and low-stage incident prostate cancer. Such anomalies in cancer research hamper efforts to fight cancer. Evidence suggests that metabolic syndrome and its components have two distinct effects in prostate cancer, concealing prostate cancer in low-stage disease and promoting progression to high-stage incident, nonlocalized, and lethal prostate cancer. The concealment of prostate cancer by metabolic syndrome and its components might be related to bias mechanisms that reduce PSA level and lead to a delayed diagnosis of low-stage prostate cancer, meaning that fewer men with metabolic syndrome are diagnosed with low-stage disease. The inverse link between metabolic syndrome and its components and low-stage incident prostate cancer might simply be the result of such bias and the shortcomings of the diagnostic procedure rather than being related to prostate cancer biology itself. The evidence summarized here supports the hypothesis that the link between metabolic syndrome and its components and incident prostate cancer is a two-way and stage-dependent one, a theory that requires further research. © 2018 Macmillan Publishers Limited, part of Springer Nature.
