Tidskriftsartikel (refereegranskat)abstract
- Purpose: Patients with Crohn’s disease have increased work loss. We aimed to describe changes in work ability in relation to pharmacological and surgical treatments. Patients and Methods: We linked data from the Swedish National Patient Register, The Swedish Quality Register for Inflammatory Bowel Disease SWIBREG, The Prescribed Drug Register, The Longitudinal Integrated Database for Health Insurance and Labour Market Studies, and the Social Insurance Database. We identified working-age (19–59 years) patients with incident Crohn’s disease 2006–2013 and population comparator subjects matched by sex, birth year, region, and education level. We assessed the number of lost workdays due to sick leave and disability pension before and after treatments.Results: Of 3956 patients (median age 34 years, 51% women), 39% were treated with aminosalicylates, 52% with immunomodulators, 22% with TNF inhibitors, and 18% with intestinal surgery during a median follow-up of 5.3 years. Most patients had no work loss during the study period (median=0 days). For all treatments, the mean number of lost workdays increased during the months before treatment initiation, peaked during the first month of treatment and decreased thereafter, and was heavily influenced by sociodemo-graphic factors and amount of work loss before first Crohn’s disease diagnosis. The mean increase in work loss days compared to pre-therapeutic level was ~3 days during the first month of treatment for all pharmacological therapies and 11 days for intestinal surgery. Three months after treatment initiation, 88% of patients treated surgically and 90–92% of patients treated pharmacologically had the same amount of work loss as before treatment start. Median time to return to work was 2 months for all treatments.Conclusion: In this regular clinical setting, patients treated surgically had more lost workdays than patients treated pharmacologically, but return to work was similar between all treatments.

- BACKGROUND: Treatment of patients with Crohn's disease has evolved in recent decades, with increasing use of immunomodulatory medication since 1990 and biologicals since 1998. In parallel, there has been increased use of active disease monitoring. To what extent these changes have influenced the incidence of primary and repeat surgical resection remains debated.METHODS: In this nationwide cohort study, incident patients of all ages with Crohn's disease, identified in Swedish National Patient Registry between 1990 and 2014, were divided into five calendar periods of diagnosis: 1990-1995 and 1996-2000 with use of inpatient registries, 2001, and 2002-2008 and 2009-2014 with use of inpatient and outpatient registries. The cumulative incidence of first and repeat abdominal surgery (except closure of stomas), by category of surgical procedure, was estimated using the Kaplan-Meier method.RESULTS: Among 21 273 patients with Crohn's disease, the cumulative incidence of first abdominal surgery within 5 years of Crohn's disease diagnosis decreased continuously from 54·8 per cent in 1990-1995 to 40·4 per cent in 1996-2000 (P < 0·001), and again from 19·8 per cent in 2002-2008 to 17·3 per cent in 2009-2014 (P < 0·001). Repeat 5-year surgery rates decreased from 18·9 per cent in 1990-1995 to 16·0 per cent in 1996-2000 (P = 0·009). After 2000, no further significant decreases were observed.CONCLUSION: The 5-year rate of surgical intervention for Crohn's disease has decreased significantly, but the rate of repeat surgery has remained stable despite the introduction of biological therapy.

Register-based and genetic studies of Prader-Willi syndrome show a high frequency of gonadal tumors and a possible mechanism for tumorigenesis through imprinting relaxation

Tidskriftsartikel (refereegranskat)abstract
- Prader-Willi syndrome (PWS) is a rare disease caused by a lack of expression of inherited imprinted genes in the paternally derived Prader-Willi critical region on chromosome 15q11.2-q13. It is characterized by poor feeding and hypotonia in infancy, intellectual disability, behavioral abnormalities, dysmorphic features, short stature, obesity, and hypogonadism. PWS is not a known cancer predisposition syndrome, but previous investigations regarding the prevalence of cancer in these patients suggest an increased risk of developing specific cancer types such as myeloid leukemia and testicular cancer. We present the results from a Swedish national population-based cohort study of 360 individuals with PWS and 18,000 matched comparisons. The overall frequency of cancer was not increased in our PWS cohort, but we found a high frequency of pediatric cancers. We also performed whole-genome sequencing of blood- and tumor-derived DNAs from a unilateral dysgerminoma in a 13-year-old girl with PWS who also developed bilateral ovarian sex cord tumors with annular tubules. In germline analysis, there were no additional findings apart from the 15q11.2-q13 deletion of the paternal allele, while a pathogenic activating KIT mutation was identified in the tumor. Additionally, methylation-specific multiplex ligation-dependent probe amplification revealed reduced methylation at the PWS locus in the dysgerminoma but not in the blood. In conclusion, our register-based study suggests an increased risk of cancer at a young age, especially testicular and ovarian tumors. We found no evidence of a general increase in cancer risk in patients with PWS. However, given our limited observational time, further studies with longer follow-up times are needed to clarify the lifetime cancer risk in PWS. We have also described the second case of locus-specific loss-of-imprinting in a germ cell tumor in PWS, suggesting a possible mechanism of carcinogenesis.

- Background & Aims: Earlier studies have provided varying risk estimates for lymphoma in patients with inflammatory bowel disease (IBD), but often have been limited by detection biases (especially during the first year of follow-up evaluation), misclassification, and small sample size; and rarely reflect modern-day management of IBD.Methods: We performed a binational register-based cohort study (Sweden and Denmark) from 1969 to 2019. We compared 164,716 patients with IBD with 1,639,027 matched general population reference individuals. Cox regression estimated hazard ratios (HRs) for incident lymphoma by lymphoma subtype, excluding the first year of follow-up evaluation.Results: From 1969 to 2019, 258 patients with Crohn's disease (CD), 479 patients with ulcerative colitis (UC), and 6675 matched reference individuals developed lymphoma. This corresponded to incidence rates of 35 (CD) and 34 (UC) per 100,000 person-years in IBD patients, compared with 28 and 33 per 100,000 person-years in their matched reference individuals. Although both CD (HR, 1.32; 95% CI, 1.16–1.50) and UC (HR, 1.09; 95% CI, 1.00–1.20) were associated with an increase in lymphoma, the 10-year cumulative incidence difference was low even in CD patients (0.08%; 95% CI, 0.02–0.13). HRs have increased in the past 2 decades, corresponding to increasing use of immunomodulators and biologics during the same time period. HRs were increased for aggressive B-cell non-Hodgkin lymphoma in CD and UC patients, and for T-cell non-Hodgkin lymphoma in CD patients. Although the highest HRs were observed in patients exposed to combination therapy (immunomodulators and biologics) or second-line biologics, we also found increased HRs in patients naïve to such drugs.Conclusions: During the past 20 years, the risk of lymphomas have increased in CD, but not in UC, and were driven mainly by T-cell lymphomas and aggressive B-cell lymphomas.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Whether data on International Classification of Diseases (ICD)-codes from the Swedish National Patient Register (NPR) correctly correspond to subtypes of inflammatory bowel disease (IBD) and phenotypes of the Montreal classification scheme among patients with prevalent disease is unknown. Materials and methods: We obtained information on IBD subtypes and phenotypes from the medical records of 1403 patients with known IBD who underwent biological treatment at ten Swedish hospitals and retrieved information on their IBD-associated diagnostic codes from the NPR. We used previously described algorithms to define IBD subtypes and phenotypes. Finally, we compared these register-generated subtypes and phenotypes with the corresponding information from the medical records and calculated positive predictive values (PPV) with 95% confidence intervals. Results: Among patients with clinically confirmed disease and diagnostic listings of IBD in the NPR (N = 1401), the PPV was 97 (96-99)% for Crohn's disease, 98 (97-100)% for ulcerative colitis, and 8 (4-11)% for IBD-unclassified. The overall accuracy for age at diagnosis was 95% (when defined as A1, A2, or A3). Examining the validity of codes representing disease phenotype, the PPV was 36 (32-40)% for colonic Crohn's disease (L2), 61 (56-65)% for non-stricturing/non-penetrating Crohn's disease behaviour (B1) and 83 (78-87)% for perianal disease. Correspondingly, the PPV was 80 (71-89)% for proctitis (E1)/left-sided colitis (E2) in ulcerative colitis. Conclusions: Among people with known IBD, the NPR is a reliable source of data to classify most subtypes of prevalent IBD, even though misclassification commonly occurred in Crohn's disease location and behaviour and also among IBD-unclassified patients.

- <b><i>Aims:</i></b> This study aimed to describe the short-term perineal healing rates in patients with perineal reconstruction using a biological mesh following extralevator abdominoperineal excision (elAPE). <b><i>Methods:</i></b> In a retrospective, descriptive single-centre cohort study, 88 consecutive patients treated with elAPE and perineal closure using a biological mesh between January 2011 and December 2015 were reviewed. All available data from electronic hospital records was collected. Patients were followed for 1 year following surgery and perineal wound status assessed at 3 months and at 1 year. <b><i>Results:</i></b> In total, 63 patients were male and all but 8 patients were treated for primary rectal cancer. All patients but 3 had received radiotherapy prior to surgery. Multivisceral excisions were performed in 19 patients. Omentoplasty was performed in 55 patients and 3 different types of meshes were used during the study period. At 3 months, 58 patients (66%) had a healed perineum. No association was detected between patient, tumour or perioperative characteristics and perineal wound status at 3 months. At 1 year, 4 patients were deceased and among the remaining 84, the perineal wound was healed in 77 patients (92%). <b><i>Conclusion:</i></b> The use of biological meshes in perineal reconstruction following elAPE is feasible and safe, and the perineal wound is healed in the majority of the patients within 3 months.

- PURPOSE: Colorectal cancer (CRC) risk is associated with modifiable lifestyle factors including smoking, physical inactivity, Western diet, and excess body weight. The impact of lifestyle factors on survival is less known. A cohort study was conducted to investigate the combined effects of a healthy lifestyle and body mass index on prognosis following CRC diagnosis.METHODS: Treatment and follow-up data were collected from the patient files of 1098 participants from the Colorectal cancer low-risk study cohort including stage I-III CRC patients. A healthy lifestyle and BMI (HL) score was computed using self-reported data on smoking status, physical activity, adherence to a Mediterranean diet pattern, and BMI, and divided into four categories ranging from least to most healthy. Survival analyses were performed to assess recurrence-free survival and overall survival across categories of exposure, using the Kaplan-Meier method and Cox proportional hazards models adjusted for age, sex, and educational level.RESULTS: Among 1098 participants with stage I-III CRC, 233 (21.2%) had an HL score of 0-1 (least healthy), 354 (32.2%) HL score of 2, 357 (32.5%) HL score of 3 and 154 (14.0) HL score 4 (most healthy). Patients with the healthiest lifestyle (HL score 4) compared to the least healthy (HL score 0-1) had an improved recurrence-free survival (HL 4 vs HL 0-1, HRadj 0.51 (95% CI 0.31-0.83) and overall survival (HL 4 vs HL 0-1, HRadj 0.52 (95% CI 0.38-0.70).CONCLUSION: Adherence to a healthy lifestyle may increase the recurrence-free and overall survival of patients with stage I-III CRC.

Tidskriftsartikel (refereegranskat)abstract
- Background: Preoperative radiotherapy and chemoradiotherapy for rectal cancer reduce local recurrence rates but is also associated with side effects. Thus, it is important to identify patients in whom the benefits exceed the risks. This study assessed the pretherapeutic parameters influencing the selection to preoperative treatment. Methods: Data on all patients in the Stockholm-Gotland area, Sweden, who underwent elective trans-abdominal surgery for rectal cancer in 2000-2010, was retrieved from the Regional Cancer Registry and the Swedish National Patient Register. Clinical variables were analysed in relation to selected preoperative therapy. Odds Ratios were derived from univariable and multivariable logistic regression models. Results: In total 2619 patients were included. Of these 1789 (68.3%) received preoperative radiotherapy or chemoradiotherapy. Over time, use of preoperative therapy increased (p < 0.001). In a multivariable model, age (>= 80 years) and comorbidity (Charlson Comorbidity Index score >= 2) were strongly correlated to omittance of preoperative treatment (OR: 0.05; 95% CI: 0.04-0.07 and 0.29; 95% CI: 0.21-0.39) but there was no difference between genders. Pre-treatment tumour stage was a strong predictor for selection to preoperative (chemo-) radiotherapy. However, 8.2% of patients with intermediate or advanced tumours were selected to no preoperative treatment while 55.0% of patients with early tumours were selected to preoperative therapy. Conclusions: The use of preoperative (chemo-) radiotherapy increased over time. Suboptimal adherence to guidelines appears to exist leading to a risk of overtreatment and to a small extent also undertreatment. More robust selection criteria, also including age and comorbidity should be developed.

Tidskriftsartikel (refereegranskat)abstract
- AIM: To investigate inflammatory bowel disease (IBD) register-based subtype classifications over a patient's disease course and over time.METHODS: We examined International Classification of Diseases coding in patients with ≥2 IBD diagnostic listings in the National Patient Register 2002-2014 (n = 44,302).RESULTS: 18% of the patients changed diagnosis (17% of adults, 29% of children) during a median follow-up of 3.8 years. Of visits with diagnoses of Crohn's disease (CD) or ulcerative colitis (UC), 97% were followed by the same diagnosis, whereas 67% of visits with diagnosis IBD-unclassified (IBD-U) were followed by another IBD-U diagnosis. Patients with any diagnostic change changed mostly once (47%) or twice (31%), 39% from UC to CD, 33% from CD to UC and 30% to or from IBD-U. Using a classification algorithm based on the first two diagnoses ('incident classification'), suited for prospective cohort studies, the proportion adult patients with CD, UC, and IBD-U 2002-2014 were 29%, 62%, and 10% (43%, 45%, and 12% in children). A classification model incorporating additional information from surgeries and giving weight to the last 5 years of visits ('prevalent classification'), suited for description of a study population at end of follow-up, classified 31% of adult cases as CD, 58% as UC and 11% as IBD-U (44%, 38%, and 18% in children).CONCLUSIONS: IBD subtype changed in 18% during follow-up. The proportion with CD increased and UC decreased from definition at start to end of follow-up. IBD-U was more common in children.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND & AIMS: Diagnosis of inflammatory bowel diseases (IBD) is increasing among elderly persons (60 years or older). We performed a nationwide population-based study to estimate incidence and treatment.METHODS: We identified all incident IBD cases in Sweden, from 2006 through 2013, using national registers, and up to 10 matched population comparator subjects. We collected data on the patients' health care contacts and estimated incidence rates, health service burden, pharmacologic treatments, extra-intestinal manifestations, and surgeries in relation to age of IBD onset (pediatric, less than 18 years; adults, 18-59 years; elderly, 60 years or older).RESULTS: Of 27,834 persons diagnosed with incident IBD, 6443 (23%) had a first diagnosis of IBD at 60 years or older, corresponding to an incidence rate of 35/100,000 person-years (10/100,000 person-years for Crohn's disease, 19 /100,000 person-years for ulcerative colitis, and 5/100,000 person-years for IBD unclassified). During a median follow-up period of 4.2 years (range 0-9 years), elderly patients had less IBD-specific outpatient health care but more IBD-related hospitalizations and overall health care use than adult patients with IBD. Compared to patients with pediatric or adult onset, elderly patients used fewer biologics and immunomodulators, but more systemic corticosteroids. Occurrence of extra-intestinal manifestations was similar in elderly and adult patients, but bowel surgery was more common in the elderly (13% after 5 years vs 10% in adults) (P<.001). The absolute risk of bowel surgery was higher in the elderly than in the general population, but in relative terms, the risk increase was larger in younger age groups.CONCLUSIONS: In a nationwide cohort study in Sweden, we associated diagnosis of IBD at age 60 years or older with a lower use of biologics and immunomodulators but higher absolute risk of bowel surgery, compared to diagnosis at a younger age. The large differences in pharmacological treatment of adults and elderly patients are not necessarily due to a milder course of disease and warrant further investigation.

Tidskriftsartikel (refereegranskat)abstract
- Background and Aims: Crohn's disease may affect the ability to work and lead to permanent disability. We aimed to investigate work loss in prevalent patients.Methods: We identified patients with Crohn's disease and general population comparators matched by sex, birth year, healthcare region and education. We assessed days of sick leave and disability pension retrieved from the Swedish Social Insurance Agency and estimated the absolute and relative risk of receiving disability pension [minimum 25% work impairment].Results: In 2014, the 20638 Crohn's disease patients [median age 44 years] had more than twice as many mean lost workdays [disability pension: 44; sick leave: 19] as the 102038 comparators [disability pension: 20; sick leave: 8], mean difference 35 days [95% confidence interval 33-37]. However, the majority had no lost workdays [68% of patients and 85% of comparators]. The proportion of patients receiving disability pension was 15% (6.5% in the comparators, risk ratio 2.34 [2.25-2.43]) and was higher in all subgroups, especially in female patients [28% vs 13% in the comparators], in those with ≤9 years of education [41% vs 23%] and in ages 60-64 years [46% vs 25%]. The relative risk of disability pension within the patient cohort [adjusted for age, sex, region and education] was higher in patients with complicated disease behaviour, extraintestinal manifestations, need of surgery or treatment with biologics. The differences between patients and comparators remained when comparing other calendar years [2006-2013].Conclusion: Work loss was found in approximately one-third of patients. The mean number of lost workdays was twice as high as in the comparators.

- Background: There are limited data on population-wide assessment of cost in Crohn's disease (CD) and ulcerative colitis (UC).Aim: To estimate the societal cost of actively treated CD and UC in Sweden.Methods: We identified 10 117 prevalent CD and 19 762 prevalent UC patients, aged ≥18 years on 1 January 2014 and 4028 adult incident CD cases and 8659 adult incident UC cases (2010-2013) from Swedish Patient Register. Each case was matched to five population comparators. Healthcare costs were calculated from medications, outpatient visits, hospitalisations and surgery. Cost of productivity losses was derived from disability pension and sick leave.Results: The mean annual societal costs per working-age patient (18-64 years) with CD and UC were $22 813 (vs $7533 per comparator) and $14 136 (vs $7351 per comparator) respectively. In patients aged ≥65 years, the mean annual costs of CD and UC were $9726 and $8072 vs $3875 and $4016 per comparator respectively. The majority of cost for both CD (56%) and UC (59%) patients originated from productivity losses. Higher societal cost of working-age CD patients as compared to UC patients was related to greater utilisation of anti-TNF (22.2% vs 7.4%) and increased annual disability pension (44 days vs 25 days). Among incident CD and UC patients, the mean total cost over the first year per patient was over three times higher than comparators.Conclusion: In Sweden, the societal cost of incident and prevalent CD and UC patients was consistently two to three times higher than the general population.

- Background and Aims: We aimed to compare the risk of frailty in older adults with incident inflammatory bowel disease (IBD) and matched non-IBD comparators and assess the association between frailty and future hospitalizations and mortality.Methods: In a cohort of patients with incident IBD ≥60 years of age from 2007 to 2016 in Sweden identified using nationwide registers, we defined frailty using Hospital Frailty Risk Score. We compared prevalence of frailty in patients with IBD with age, sex, place of residency– and calendar year–matched population comparators. In the IBD cohort, we used Cox proportional hazards modeling to examine the associations between frailty risk and hospitalizations or mortality.Results: We identified 10,590 patients with IBD, 52% female with a mean age of 71 years of age, matched to 103,398 population-based comparators. Among patients with IBD, 39% had no risk for frailty, 49% had low risk for frailty, and 12% had higher risk for frailty. Mean Hospital Frailty Risk Score was 1.9 in IBD and 0.9 in matched comparators (P < .01). Older adults with IBD at higher risk for frailty had a 20% greater risk for mortality at 3 years compared with those who were not frail. Compared with nonfrail older patients with IBD, patients at higher risk for frailty had increased mortality (hazard ratio [HR], 3.22, 95% confidence interval [CI], 2.86–3.61), all-cause hospitalization (HR, 2.42; 95% CI, 2.24–2.61), and IBD-related hospitalization (HR, 1.50; 95% CI, 1.35–1.66). These associations were not attenuated after adjusting for comorbidities.Conclusions: Frailty is more prevalent in older adults with IBD than in matched comparators. Among older patients with IBD, frailty is associated with increased risk for hospitalizations and mortality.
