    • We have previously demonstrated an association between neonatal phototherapy and/or neonatal icterus and risk of hospitalization for childhood asthma. This study included children who were prescribed anti-asthmatic medication on a population basis to study exposures during the foetal and neonatal period and risk of childhood asthma. The Swedish Medical Birth Register was linked to the Swedish Prescribed Drug Register. Perinatal data for singleton children who were prescribed anti-asthmatic medication (n = 61 256) were compared with corresponding data for all singleton children born in Sweden from 1 January 1990 to 30 June 2003 and surviving to 1 July 2005 (n = 1 338 319). Mantel-Haenszel's odds ratios were calculated after adjustment for various known confounders. Being the first-born child, maternal age above 44 yr, involuntary childlessness for more than 1 yr, maternal smoking during pregnancy, maternal diabetes mellitus of any kind, pre-eclampsia, caesarean section, and instrumental vaginal delivery were all associated with an increased prescription of anti-asthmatic medication during childhood. Preterm birth, low birth weight, being small for gestational age, respiratory problems, mechanical ventilation, and sepsis and/or pneumonia were also associated with increased drug prescriptions. Neonatal phototherapy and/or icterus were risk determinants for children who developed asthma before the age of 12. After controlling for confounders, the odds ratio for phototherapy and/or icterus remained at 1.30 (95% confidence interval 1.16-1.47). In conclusion, this large population-based study confirms an association between some maternal and perinatal factors and childhood asthma, including neonatal phototherapy and/or icterus.

  • Fetal and perinatal risk factors for inflammatory bowel disease
  • 2006
  • Ingår i: Acta Pædiatrica. - : Wiley. - 1651-2227 .- 0803-5253. ; 95:8, s. 1001-1004

    • Aim: To study the influence of specific factors and events during pregnancy and the perinatal period on the risk of children developing inflammatory bowel disease. Methods: Population-based national register study. Linkage between the Swedish Medical Birth Register and the Swedish Hospital Discharge Register during the period 1987 to 2000 identified 455 singleton infants who later developed inflammatory bowel disease. Data for these children were compared with data for all children born in Sweden during the same period. Results: Smoking during early pregnancy reduced the risk of inflammatory bowel disease ( odds ratio ( OR) 0.71, 95% CI 0.55-0.91). For ulcerative colitis the odds ratio was 0.70 ( 95% CI 0.56-0.86), and for Crohn's disease 0.73 ( 95% CI 0.58 - 0.94). Infections during the neonatal period seemed to increase the risk of inflammatory bowel disease ( OR 17.6, 95% CI 3.6 - 51.6), but the number of observed events was small. The other factors examined did not influence the risk of inflammatory bowel disease. Conclusion: Maternal smoking during early pregnancy reduces the risk for the child to be hospitalized with a diagnosis of inflammatory bowel disease. Severe neonatal infections may increase the risk. Thus, some exposures during the fetal and neonatal period seem to affect the risk of inflammatory bowel disease later in life.

  • Is neonatal phototherapy associated with an increased risk for hospitalized childhood bronchial asthma?
  • 2007
  • Ingår i: Pediatric Allergy and Immunology. - : Wiley. - 0905-6157 .- 1399-3038. ; 18:4, s. 313-319
  • Tidskriftsartikel (refereegranskat)abstract
    • This population-based register study examined if factors during the fetal and neonatal period influence the risk for the child to develop bronchial asthma (asthma). From the Swedish Hospital Discharge Register we identified children, born between 1987 and 1999, who had been hospitalized for asthma up to 2001. Thus, the outcome measure contains only hospitalized cases, not all children with asthma. Children younger than 2 yr at admission were excluded because of the uncertainty about the diagnosis of asthma in younger children. The remaining 14,803 children were compared with all children born the same years, recorded in the Swedish Medical Birth Registry, for information on pre- and perinatal characteristics. Odds ratios (ORs) were calculated with Mantel-Haenszel technique and 95% confidence intervals (CIs) with Miettinen's test-based method. The presence of various maternal and neonatal confounders were identified and adjusted for in the analyses. The association between some known factors and childhood asthma were confirmed: young maternal age, maternal smoking, period of unwanted childlessness, low maternal level of education, maternal diabetes, preterm birth, low birth weight, small-for-gestational age, caesarean section, and instrumental vaginal delivery. A number of neonatal characteristics were shown to be independent risk factors: sepsis or pneumonia, neonatal respiratory problems and treatments, neonatal icterus, and/or neonatal phototherapy. The association with icterus and phototherapy remained after exclusion of cases showing other neonatal risk factors and after adjustment for maternal factors (OR 1.27, 95% CI: 1.08-1.50), and increased to 1.5 if the children had been hospitalized for asthma more than once. In conclusion, our results suggest an association between neonatal icterus and/or treatment with neonatal phototherapy and hospitalized childhood asthma. This association needs further exploration.

  • Hypertoni är största hotet mot global hälsa : ger ökad risk för framför allt hjärt–kärlsjukdom, demens och njursjukdom
  • 2013
  • Ingår i: Läkartidningen. - : Läkartidningen förlag AB. - 0023-7205 .- 1652-7518. ; 110:22, s. 1088-1089

    • Förhöjt blodtryck är i dag den viktigaste riskfaktorn av global betydelse för den totala sjukdomsbördan. Medelblodtrycket (åldersjusterat) sjunker i västerländska befolkningar. I Sverige beräknas omkring 2 miljoner individer ha hypertoni, och andelen ökar med en åldrande befolkning. Behandling av hypertoni ger stora behandlingsvinster. Trots detta når bara en av tre behandlade patienter i svensk sjukvård målblodtryck (lägre än 140/90 mm Hg).

  • Renal sympathetic denervation in Sweden : a report from the Swedish registry for renal denervation
  • 2018
  • Ingår i: Journal of Hypertension. - : Lippincott Williams & Wilkins. - 0263-6352 .- 1473-5598. ; 36:1, s. 151-158
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Renal denervation (RDN) is a catheter-based intervention to treat patients with resistant hypertension. The biological effects of RDN are not fully understood, and randomized controlled trials have generated conflicting evidence. This report presents data from the Swedish Registry for Renal Denervation, an investigator-driven nationwide registry. Purpose: To assess the safety and efficacy of RDN on patients with resistant hypertension in a real-world clinical setting. Methods: This nationwide database contains patient characteristics, procedural details, and follow-up data on all RDN procedures performed in Sweden. Consecutive procedures between 2011 and 2015 were included. Results: The data analysis consists of 252 patients (mean age 61 +/- 10 years, 38% women; mean 4.5 +/- 1.5 antihypertensive drugs). Office SBP and DBP and 24-h ambulatory blood pressure (BP) decreased 6 months after RDN (176 +/- 23/97 +/- 17 to 161 +/- 26/91 +/- 16 mmHg, both P<0.001; and 155 +/- 17/89 +/- 14 to 147 +/- 18/82 +/- 12 mmHg, both P<0.001). Significant office and ambulatory BP reductions persisted throughout the observation period of 36 months. Major procedure-related vascular complications occurred in four patients. Renal function and number of antihypertensive drugs were unchanged during follow-up. Conclusion: In this complete national cohort, RDN was associated with a sustained reduction in office and ambulatory BP in patients with resistant hypertension. The procedure proved to be feasible and associated with a low-complication rate, including long-term adverse events.
