  • Evidence of poor vitamin status in coeliac patients on a gluten-free diet for 10 years
  • 2002
  • Ingår i: Alimentary Pharmacology and Therapeutics. - : Wiley. - 0269-2813 .- 1365-2036. ; 16:7, s. 1333-1339

    • Background: Patients with coeliac disease are advised to keep to a lifelong gluten-free diet to remain well. Uncertainty still exists as to whether this gives a nutritionally balanced diet. Aim: To assess the vitamin nutrition status of a series of coeliac patients living on a gluten-free diet for 10 years. Methods: Thirty adults with coeliac disease (mean age, 55 years, range, 45-64 years, 60% women), in biopsy-proven remission following 8-12 years of dietary treatment, were studied. We measured the total plasma homocysteine level, a metabolic marker of folate, vitamin B-6 and vitamin B-12 deficiency, and related plasma vitamin levels. The daily vitamin intake level was assessed using a 4-day food record. Normative data were obtained from the general population of the same age. Results: Coeliac patients showed a higher total plasma homocysteine level than the general population, indicative of a poor vitamin status. In accordance, the plasma levels of folate and pyridoxal 5'-phosphate (active form of vitamin B-6) were low in 37% and 20%, respectively, and accounted for 33% of the variation of the total plasma homocysteine level (P < 0.008). The mean daily intakes of folate and vitamin B-12, but not of vitamin B-6, were significantly lower in coeliac patients than in controls. Conclusions: Half of the adult coeliac patients carefully treated with a gluten-free diet for several years showed signs of a poor vitamin status. This may have clinical implications considering the linkage between vitamin deficiency, elevated total plasma homocysteine levels and cardiovascular disease. The results may suggest that, when following up adults with coeliac disease, the vitamin status should be reviewed.

  • Living with coeliac disease - Controlled study of the burden of illness
  • 2002
  • Ingår i: Scandinavian Journal of Gastroenterology. - 0036-5521 .- 1502-7708. ; 37:1, s. 39-42
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Coeliac patients improve vastly when started on a.-gluten-free diet. After 10 years, however, women show a lower level of subjective health than men do. We investigated whether this could be explained by differences in the perceived disease burden. Methods: We studied 68 coeliac patients (34 women) (mean age 57 years, range 32-75) and matched type-2 diabetes controls treated for a mean of 10 years. They were examined by a 9-item Burden of Illness (BI) protocol comprising perceived worries, restriction., and subjective outcome. The subjective health was assessed with the Short Form 36 Health Survey (SF-36) questionnaire. Results: The importance of complying with the diet was ranked similarly high by male and female coeliac patients, However, women were less satisfied with the outcome at 10 years than men were, and expressed more concern about the impact on socializing with friends and having to abstain from important things in life. None of these aspects distinguished male and female diabetic patients, Coeliac women showed a higher BI sum score than men did, and this was inversely related to their SF-36 General health, Vitality and Mental Health scores. Conclusions: Coeliac women adhering to the treatment regimen for several years perceive the disease burden to be worse than men do. In the light of similar differences in their quality of life, inquiry is warranted into the way coeliac men and women are coping with the disorder.

  • Antibody levels in adult patients with coeliac disease during gluten free diet a rapid initial decrease of clinical importance
  • 2004
  • Ingår i: Journal of Internal Medicine. - : Wiley. - 0954-6820 .- 1365-2796. ; 256:6, s. 519-524
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. Analysis of antibodies against tissue transglutaminase (tTG) has been shown valuable in the diagnosis of coeliac disease (CD) but how quickly serum titres decrease after introduction of a gluten-free diet (GFD) is not known in adults. CD is a well-recognized disorder amongst the general population and many persons try a GFD for fairly vague symptoms before they seek medical advice. Therefore, it is important to determine the time that the serologic tests remain predictive of the disease after the introduction of a GFD. Methods. Sera were taken from 22 consecutively biopsy-proven adult patients with CD in connection with the diagnostic biopsy. The patients were followed for 1 year and sera were taken after 1, 3, 6 and 12 months after start of a GFD. Sera were stored at −20 °C and analysed for IgA antibodies against gliadin, endomysium and two different commercial tTG assays based on recombinant human tTG (tTGrh) and guinea-pig liver (tTGgp). Results. Twenty patients could be followed during GFD and all antibody titres fell sharply within 1 month after introduction of a GFD and continued to decline during the survey interval. Thirty days after beginning the diet only 58, 84, 74 and 53% of all patients had positive antibody levels of tTGrh, tTGgp, EmA and AGA respectively. Conclusions. As the antibodies used to confirm the diagnosis of CD fall rapidly and continue to decline following the introduction of a GFD, it is important that health care providers carefully inquire about the possibility of self-prescribed diets before patients sought medical attention.

  • Mannan-binding lectin and complement C4A in Icelandic multicase families with systemic lupus erythematosus
  • 2006
  • Ingår i: Annals of the Rheumatic Diseases. - : BMJ. - 0003-4967 .- 1468-2060. ; 65:11, s. 1462-7
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To determine whether low mannan-binding lectin (MBL) and C4A null alleles (C4AQ0) are associated with systemic lupus erythematosus (SLE) in multicase families with SLE. Methods: Low MBL level was determined by measuring serum levels and by genotyping for mutant structural (B/C/D, designated as 0) and promoter (LX) alleles (by real-time polymerase chain reaction). C4AQ0 was detected by protein electrophoresis and corroborated with haplotype and genotype analysis. In nine Icelandic families, 24 patients with SLE were compared with 83 first-degree and 23 second-degree relatives without SLE. Twenty four unrelated family members and a population group of 330 Icelanders served as controls. Results: Overall, the frequency of low MBL genotypes (0/0, LX/0 and wild-type/0) tended to be higher in patients with SLE than in their first-degree and second-degree relatives (p = 0.06), but the frequency was similar in the families and in the controls (p = 0.6). The frequency of C4AQ0 was, however, increased in patients and their relatives compared with that in the controls (p = 0.04). The combination of low MBL genotypes and C4AQ0 was found more often in the patients than in their relatives (p = 0.03) and controls (p = 0.02). However, low MBL level was observed only in patients and first-degree relatives in five of the nine multicase families. In these five families, patients with SLE had low MBL genotypes more often (64%) than their first-degree (38%) and second-degree (0%) relatives (p = 0.001), and the patients with SLE also had, accordingly, lower MBL levels than their relatives (p = 0.001). Conclusions: These findings indicate that low MBL levels can predispose people to SLE and highlight the genetic heterogeneity of this disease.

  • Liver-first strategy for synchronous colorectal liver metastases : an intention-to-treat analysis
  • 2017
  • Ingår i: HPB. - : Elsevier BV. - 1365-182X. ; 19:1, s. 52-58
  • Tidskriftsartikel (refereegranskat)abstract
    • Background The liver-first strategy signifies resection of liver metastases before the primary colorectal cancer. The aim of the present study was to compare failure to complete intended treatment and survival in liver-first and classical strategies. Methods All patients with colorectal cancer and synchronous liver metastases planned for sequential radical surgery in a single institution between 2011 and 2015 were included. Results A total of 109 patients were presented to a multidisciplinary team conference (MDT) with un-resected colorectal cancer and synchronous liver metastases. Seventy-five patients were planned as liver-first, whereas 34 were recommended the classical strategy. Twenty-six patients (35%) failed to complete treatment in the liver-first group compared to 10 patients in the classical group (P = 0.664). Reason for failure was most commonly disease progression. A total of 91 patients had the primary tumor resected before the liver metastases of which 67 before referral and 24 after allocation at MDT. Median survival after diagnosis in this group was 60 (48–73) months compared to 46 (31–60) months in the group operated with liver-first strategy (n = 49), (P = 0.310). Discussion Up to 35% of patients with colorectal cancer and synchronous liver metastases do not complete the intended treatment of liver and bowel resections, irrespective of treatment strategy.

  • Three years' follow-up of bone density in adult coeliac disease : Significance of secondary hyperparathyroidism
  • 2000
  • Ingår i: Scandinavian Journal of Gastroenterology. - 0036-5521 .- 1502-7708. ; 35:3, s. 274-280
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The mechanisms of disturbances in bone mineral density (BMD) in coeliac disease are not completely understood. The aim of this prospective study was to investigate the possible significance of secondary hyperparathyroidism (SHPT) with regard to BMD in patients with untreated coeliac disease. Methods: One hundred and five adult patients with untreated coeliac disease were examined for BMD and serum parathyroid hormone (PTH) concentration. BMD in the hip, lumbar spine, and forearm were examined up to 3 years after the introduction of a gluten-free diet. Results: SHPT was found in 27% (28 of 105) of the patients. In patients with SHPT serum levels of 25- hydroxy-vitamin D were lower and those of alkaline phosphatase higher than in patients with normal PTH, but ionized serum calcium did not differ between the two groups. BMD was more severely reduced in patients with SHPT. Although the BMD increment was more rapid in patients with than in those without SPTH, only in the latter group did mean BMD became normal after 1-3 years on a gluten-free diet (GFD). After 3 years on a GFD more than half of the patients with initial SHPT still had low BMD in both the hip and the forearm. Furthermore, in patients with SHPT the intestinal mucosa more often remained atrophic at the 1-year follow-up, despite good compliance with the diet. Conclusions: Low BMD in patients with untreated coeliac disease is often associated with SHPT. After 3 years on a GFD the BMD remains low only in patients with initial SHPT. We therefore suggest that PTH should be measured when the diagnosis of coeliac disease is made, as an indicator of more serious intestinal disorder and complicating bone disease.

  • Outcomes of liver-first strategy and classical strategy for synchronous colorectal liver metastases in Sweden
  • 2018
  • Ingår i: HPB. - : Elsevier BV. - 1365-182X .- 1477-2574. ; 20:5, s. 441-447
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Patients with synchronous colorectal liver metastases (sCRLM) are increasingly operated with liver resection before resection of the primary cancer. The aim of this study was to compare outcomes in patients following the liver-first strategy and the classical strategy (resection of the bowel first) using prospectively registered data from two nationwide registries. Methods: Clinical, pathological and survival outcomes were compared between the liver-first strategy and the classical strategy (2008-2015). Overall survival was calculated. Results: A total of 623 patients were identified, of which 246 were treated with the liver-first strategy and 377 with the classical strategy. The median follow-up was 40 months. Patients chosen for the classical strategy more often had T4 primary tumours (23% vs 14%, P = 0.012) and node-positive primaries (70 vs 61%, P = 0.015). The liver-first patients had a higher liver tumour burden score (4.1 (2.5-6.3) vs 3.6 (2.2-5.1), P = 0.003). No difference was seen in five-year overall survival between the groups (54% vs 49%, P = 0.344). A majority (59%) of patients with rectal cancer were treated with the liver-first strategy. Conclusion: The liver-first strategy is currently the dominant strategy for sCRLM in patients with rectal cancer in Sweden. No difference in overall survival was noted between strategies.
