  • Nonfatal stroke, cardiac disease, and diabetes mellitus in hypopituitary patients on hormone replacement including growth hormone
  • 2007
  • Ingår i: Journal of Clinical Endocrinology and Metabolism. - : The Endocrine Society. - 1945-7197 .- 0021-972X. ; 92:9, s. 3560-3567
  • Tidskriftsartikel (refereegranskat)abstract
    • Context: The impact of long-term GH replacement on cerebrovascular and cardiovascular diseases and diabetes mellitus in hypopituitary patients is unknown. Objective: The incidence of nonfatal stroke and cardiac events, and prevalence of type 2 diabetes mellitus ( T2D) and cardioprotective medication were compared between cohorts of GH-deficient (GHD) patients and population controls. Design and Participants: The incidence of nonfatal stroke and cardiac events was estimated retrospectively from questionnaires in 750 GHD patients and 2314 matched population controls. A prevalence of T2D and cardioprotective medication was recorded at the distribution of questionnaires. Time since first pituitary deficiency to start of GH therapy was 4 and 2 yr, and time on GH therapy was 6 yr for GHD women and men, respectively. Results: Lifelong incidence of nonfatal stroke was tripled in GHD women and doubled in GHD men, but a decline was seen in both genders during periods after first pituitary hormone deficiency and GHD, during which most patients had GH therapy. The lifelong incidence of nonfatal cardiac events declined in GHD men during first pituitary hormone deficiency and GHD periods. GHD women had a higher prevalence of T2D and lipid-lowering medication, whereas GHD men had a higher prevalence of antihypertensive medication. Conclusions: The declined risks of nonfatal stroke in both genders and of nonfatal cardiac events in GHD men during periods on GH replacement may be caused by prescription of cardioprotective drugs and 6-yr GH replacement. GHD women had an increased prevalence of T2D, partly attributed to higher body mass index and lower physical activity.

  • A retrospective 30-year follow-up study of former Swedish-elite male athletes in power sports with a past anabolic androgenic steroids use: a focus on mental health.
  • 2013
  • Ingår i: British journal of sports medicine. - : BMJ. - 1473-0480 .- 0306-3674. ; 47:15, s. 965-969
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The knowledge concerning the long-term effect of former anabolic androgenic steroids (AAS)-use on mental health is sparse. AIM: This study aims to investigate whether previous AAS-use affects mental health, present sociodemographic data, sport activity and substance abuse in a retrospective 30-year follow-up study of former elite athletes. METHODS: Swedish male-elite power sport athletes (n=683) on the top 10 national ranking lists during any of the years 1960-1979 in wrestling, Olympic lifting, powerlifting and the throwing events in track and field answered a questionnaire. RESULTS: At least 20% of the former athletes admitted previous AAS-use. They had more often sought professional expertise for mental problems and had used illicit drugs compared to those not having used AAS. The AAS-users also differed in former sport activity pattern compared to non AAS-users. CONCLUSIONS: It is clear that a relationship exists between use of AAS and mental-health problems. Further studies need to be done in order to clarify this relationship.

  • Traumatisk hjärnskada kan ge hypofyssvikt : Förslag till riktlinjer för utvärdering av hypofysfunktionen
  • 2012
  • Ingår i: Läkartidningen. - : Läkartidningen förlag AB. - 0023-7205 .- 1652-7518. ; 109:12, s. 629-632
  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • Traumatisk hjärnskada (traumatic brain injury, TBI) är en av de vanligaste orsakerna till död och nedsatt funktion hos människor i arbetsför ålder. Patienter som överlever svåra skallskador utgör en växande patientkategori inom dagens sjukvård. På senare år har det aktualiserats att allvarligt skalltrauma kan ge skador i hypofys–hypotalamusregionen. Det är angeläget att dessa patienter utreds för eventuell hypofyssvikt så att hormonell substitutionsterapi kan inledas om endokrin insufficiens fastställs. Detta kan förhoppningsvis underlätta efterföljande rehabilitering och därmed förbättra pro­gnosen. Vi presenterar här ett förslag till riktlinjer för utvärdering av hypofysfunktionen hos TBI-patienter. Samtidigt vill vi informera en bredare läsekrets om TBI-begreppet.

  • The incidence rate of pituitary adenomas in western Sweden for the period 2001-2011
  • 2014
  • Ingår i: European Journal of Endocrinology. - 0804-4643 .- 1479-683X. ; 171:4, s. 519-526
  • Tidskriftsartikel (refereegranskat)abstract
    • © 2014 European Society of Endocrinology. Objective: The number of studies on the incidence of pituitary adenomas (PAs) is limited. The aim of this study was to evaluate the standardised incidence rate (SIR) of PAs in western Sweden.Design, subjects and methods: Data from adult patients diagnosed with PAs in 2001-2011, living in the Vä stra Götaland County, were collected from the Swedish Pituitary Registry (SPR). In addition, medical records on all patients diagnosed with PAs at the six hospitals in the region were reviewed. In total, 592 patients were included in the study.Age-SIR, given as rate/100 000 inhabitants (95% CI), was calculated using the WHO 2000 standard population as a reference.Results: The total SIRfor PAswas 3.9/100 000 (3.6-4.3); 3.3/100 000 (2.9-3.7) formen and 4.7/100 000 (4.1-5.3) forwomen. Inmen, SIR increasedwith age, while inwomen SIR peaked at 25-34 years, mainly due to prolactinomas. Non-functioning PA (NFPA)was the most common PA (54%, 1.8/100 000 (1.6-2.0)) followed by prolactinomas (32%, 1.6/100 000 (1.3-1.9)), acromegaly (9%, 0.35/100 000 (0.25-0.45)), Cushing'sdisease (4%, 0.18/100 000 (0.11-0.25)) andTSH-producingPA(0.7%, 0.03/100 000 (0.00-0.05)). The proportion of macroadenomas for NFPA was 82%, prolactinomas 37%, GH-producing PA 77%, ACTH-producing PA 28% and TSH-producing PA 100%. The lifetime risk for PAs was 0.27% (0.24-0.31) in men and 0.29% (0.26-0.33) in women.Conclusion: This study provides a reliable estimate on the overall incidence of PAs and confirms an increased incidence of PAs compared with studies conducted in the pre-magnetic resonance imaging era. The lower proportion of prolactinomas compared with previous studies is probably explained by the different criteria used.

  • Comparison of methods to estimate body fat in growth hormone deficient adults.
  • 1996
  • Ingår i: Clinical endocrinology. - 0300-0664. ; 44:4, s. 395-402
  • Tidskriftsartikel (refereegranskat)abstract
    • All of the presently used methods for in-vivo determination of body composition have inherent methodological errors and depend on various assumptions. We have therefore compared several different methods used to measure body fat in adult GH deficiency during GH treatment.Comparison of body composition data from a two-phase trial with an initial placebo-controlled, double-blind 6-month period, followed by open treatment with GH until all patients had received GH for 12 months.Twenty-five patients with known GH deficiency entered the study. Baseline examinations were complete in 23 patients, and 22 patients (16 males, 6 females) completed all examinations after treatment.Body fat calculated from total body potassium (TBK) by whole-body 40K counting, total body water (TBW) by tritium dilution, total body nitrogen (TBN) by neutron activation, and bioelectric impedance (BIA) measurements were compared to body fat determinations by dual-energy X-ray absorptiometry (DEXA) in two-compartment and multicompartment body composition models.At baseline, DEXA fat mass agreed well at group level with measurements based on TBW or TBK alone, in a four-compartment model based on TBK and TBW, and a multicompartment model based on bone mineral (by DEXA), TBN and TBW. Body fat by BIA agreed less well. After 12 months of GH treatment, body fat decreased by all methods used. This decrease was smaller by DEXA than by the other methods. The four-compartment model based on TBK and TBW, and TBW alone, showed the best agreement with changes in DEXA fat.All methods showed a decrease of body fat with GH treatment, but variation between methods was considerable.

  • Low concentrations of serum testosterone predict acute myocardial infarction in men with type 2 diabetes mellitus
  • 2015
  • Ingår i: Bmc Endocrine Disorders. - : Springer Science and Business Media LLC. - 1472-6823. ; 15
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The aim of the present study was to investigate the associations between endogenous testosterone concentrations and the incidence of acute myocardial infarction (AMI) in men and women with and without type 2 diabetes. Methods: The study comprised 1109 subjects >= 40 years of age (mean age 62 +/- 12 years) participating in a baseline survey in Sweden in 1993-94. Information about smoking habits and physical activity was obtained using validated questionnaires. Serum concentrations of testosterone and sex hormone-binding globulin (SHBG) were obtained using radioimmunoassay. Diagnosis of type 2 diabetes was based on WHO's 1985 criteria. Individual patient information on incident AMI was ascertained by record linkage with national inpatient and mortality registers from baseline through 2011. Results: The prevalence of type 2 diabetes at baseline was 10.0 % in men and 7.5 % in women. During a mean follow-up of 14.1 years (+/- 5.3), there were 74 events of AMI in men and 58 in women. In age-adjusted Cox models, a significant inverse association between concentrations of testosterone and AMI-morbidity was found in men with type 2 diabetes (HR = 0.86 CI (0.75-0.98)). In a final model also including waist-to-hip ratio, systolic blood pressure, total cholesterol and active smoking, the association still remained statistically significant (HR = 0.754 CI (0.61-0.92)). Conclusion: Low concentrations of testosterone predicted AMI in men with type 2 diabetes independent of other risk factors. Trials with testosterone investigating the effect regarding cardiovascular outcome are still lacking. Future trials in this field should take into account a modification effect of diabetes.

  • Low sex hormone-binding globulin is associated with hypertension: a cross-sectional study in a Swedish population
  • 2013
  • Ingår i: BMC Cardiovascular Disorders. - : Springer Science and Business Media LLC. - 1471-2261. ; 13
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The aim of this study was to investigate the association of sex hormone-binding globulin (SHBG) and hypertension in a Swedish population. Methods: The study is based on a random sample of a Swedish population of men and women aged 30-74 years (n=2,816). Total testosterone, oestradiol and SHBG were measured in 2,782 participants. Free androgen index was then calculated according to the formula FAI=100 x (Total testosterone)/SHBG. Hypertension was diagnosed according to JNC7. Results: In men, but not in women, significant association between SHBG and both diastolic (diastolic blood pressure: beta=-0.143 p<0.001) and systolic blood pressure (systolic blood pressure beta=-0.114 p<0.001) was found. The association was still significant after adjusting for age, body mass index (BMI), homeostatic model assessment insulin resistance (HOMA-IR), triglycerides, high density lipoproteins (HDL) and C-reactive protein (CRP) (diastolic blood pressure: beta=-0.113 p<0.001; systolic blood pressure beta=-0.093 p=0.001). An inverse association was observed between SHBG and hypertension in both men (B=-0.024 p<0.001) and women (B=-0.022 p<0.001). The association was still significant in women older than 50 years after adjustments for age, BMI, physical activity, CRP and alcohol consumption (B=-0.014, p=0.008). Conclusion: In conclusion, these results show a strong association between SHBG and blood pressure independent of major determinants of high blood pressure. This association might be addressed to direct effects of SHBG in endothelial cells through the receptor for SHBG. If this is confirmed by other observational and experimental studies, it might become a new field for the development of therapies for lowering blood pressure.

  • Fracture incidence in GH-deficient patients on complete hormone replacement including GH
  • 2007
  • Ingår i: Journal of Bone and Mineral Research. - : Wiley. - 0884-0431 .- 1523-4681. ; 22:12, s. 1842-1850

    • Fracture risk in GHD patients is not definitely established. Studying fracture incidence in 832 patients on GH therapy and 2581 matched population controls, we recorded a doubled fracture risk in CO GHD women, but a significantly lower fracture risk in AO GHD men. Introduction: The objective of this study was to evaluate fracture incidence in patients wilh confirmed growth hormone deficiency (GHD) on replacement therapy (including growth hormone [GH]) compared with population controls, while also taking potential confounders and effect modifiers into account. Materials and Methods: Eight hundred thirty-two patients with GHD and 2581 matched population controls answered a questionnaire about fractures and other background information. Incidence rate ratio (IRR) and 95% CI for first fracture were estimated. The median time on GH therapy for childhood onset (CO) GHD men and women was 15 and 12 yr, respectively, and 6 and 5 yr for adult onset (AO) GHD men and women, respectively. Results: A more than doubled risk (IRR, 2.29; 95% CI, 1.23-4.28) for nonosteoporotic fractures was recorded in women with CO GHD, whereas no risk increase was observed among CO GHD men (IRR. 0.61) and AO GHD women (IRR, 1.08). A significantly decreased incidence of fractures (IRR, 0.54; 95% CI 0.34-0.86) was recorded in AO GHD men. Conclusions: Increased fracture risk in CO GHD women can most likely be explained by interaction between oral estrogen and the GH-IGF-I axis. The adequate substitution rate of testosterone (90%) and GH (94%) may have resulted in significantly lower fracture risk in AO GHD men.

  • Increased mortality rate and suicide in Swedish former elite male athletes in power sports.
  • 2014
  • Ingår i: Scandinavian journal of medicine & science in sports. - : Wiley. - 1600-0838 .- 0905-7188. ; 24:6, s. 1000-1005
  • Tidskriftsartikel (refereegranskat)abstract
    • Physical training has been shown to reduce mortality in normal subjects, and athletes have a healthier lifestyle after their active career as compared with normal subjects. Since the 1950s, the use of anabolic androgenic steroids (AAS) has been frequent, especially in power sports. The aim of the present study was to investigate mortality, including causes of death, in former Swedish male elite athletes, active 1960-1979, in wrestling, powerlifting, Olympic lifting, and the throwing events in track and field when the suspicion of former AAS use was high. Results indicate that, during the age period of 20-50 years, there was an excess mortality of around 45%. However, when analyzing the total study period, the mortality was not increased. Mortality from suicide was increased 2-4 times among the former athletes during the period of 30-50 years of age compared with the general population of men. Mortality rate from malignancy was lower among the athletes. As the use of AAS was marked between 1960 and 1979 and was not doping-listed until 1975, it seems probable that the effect of AAS use might play a part in the observed increased mortality and suicide rate. The otherwise healthy lifestyle among the athletes might explain the low malignancy rates.
