- OBJECTIVE—To estimate the prevalence and severity of diabetic retinopathy (DR) 10 years after diagnosis in a nationwide population-based cohort study of young adult diabetic patients in Sweden. RESEARCH DESIGN AND METHODS—The Diabetes Incidence Study in Sweden (DISS) aims to register all incident cases of diabetes aged 15–34 years in Sweden. In 1987–1988, 806 cases were reported, and 627 (78%) of them were followed up with regard to retinopathy 8–10 years later. The assessment was based on retinal photographs in most cases (86%). RESULTS—Ten years after diagnosis, retinopathy was found in 247 patients (39%). The retinopathy was mild in 206 (33%), whereas 30 (4.8%) patients had moderate nonproliferative DR (NPDR) and 11 (1.8%) had proliferative DR (PDR). Patients with retinopathy had worse glycemic control during the years than patients without (HbA1c 8.1 ± 1.5% and 6.8 ± 1.2%, respectively; P < 0.001). In a Cox regression analysis, time to retinopathy was related to high HbA1c (P < 0.001) and high BMI (P = 0.001). Patients with type 2 diabetes had an increased prevalence of severe retinopathy (NPDR or PDR) compared with those with type 1 diabetes (14 of 93 [15%] versus no or mild 24 of 471 [5%], respectively; P < 0.001). CONCLUSIONS—Despite modern diabetes management, 39% of young adult diabetic patients developed retinopathy within the first 10 years of the disease. Nevertheless, compared with the prevalence of retinopathy (63%), after a similar duration of diabetes before the Diabetes Control and Complications Trial, this prevalence was clearly lower. Current treatment aimed to achieve strict glycemic control has reduced the risk for developing retinopathy.

- Low plasma vitamin D concentrations may promote the development of type 1 diabetes. To test this hypothesis, we measured plasma 25-hydroxyvitamin D (25OHD) in young adults with type 1 diabetes.The nationwide Diabetes Incidence Study in Sweden (DISS) covers 15- to 34-year-old people with newly diagnosed diabetes. Blood samples at diagnosis were collected during the 2-year period 1987/1988. Patients with islet antibodies (islet cell antibodies, GAD antibodies or tyrosine phosphatase-like protein antibodies) were defined as having autoimmune type 1 diabetes. Plasma 25OHD was measured in samples taken from 459 patients at the time of diagnosis, and in 138 of these subjects 8 years later. The results were compared with age- and sex-matched control subjects (n=208).At diagnosis, plasma 25OHD levels were significantly lower in patients with type 1 diabetes than in control subjects (82.5 +/- 1.3 vs 96.7 +/- 2.0 nmol/l; p < 0.0001). Eight years later, plasma 25OHD had decreased in patients (81.5 +/- 2.6 nmol/l; p=0.04). Plasma 25OHD levels were significantly lower in diabetic men than in diabetic women at diagnosis (77.9 +/- 1.4 vs 90.1 +/- 2.4 nmol/l; p < 0.0001) and at follow-up (77.1 +/- 2.8 nmol/l vs 87.2 +/- 4.5 nmol/l; p=0.048). 81.5 +/- 2.6 nmol/l; p=0.04). Plasma 25OHD levels were significantly lower in diabetic men than in diabetic women at diagnosis (77.9 +/- 1.4 vs 90.1 +/- 2.4 nmol/l; p < 0.0001) and at follow-up (77.1 +/- 2.8 nmol/l vs 87.2 +/- 4.5 nmol/l; p=0.048). Conclusions/interpretation The plasma 25OHD level was lower at diagnosis of autoimmune type 1 diabetes than in control subjects, and may have a role in the development of type 1 diabetes. Plasma 25OHD levels were lower in men than in women with type 1 diabetes. This difference may be relevant to the high incidence of type 1 diabetes among young adult men.

- This national registry-based study compares surgical procedures, demography, and concurrent medical conditions, in internationally adopted and Swedish-born children with cleft lip and/or palate until the age of five years. Data on the cleft type and gender for 331 internationally adopted children and 2064 Swedish-born children born from 2007 to 2018, were extracted from the registry and analyzed. Data on surgical procedures performed in Sweden and concurrent medical conditions and were collected for internationally adopted children and Swedish-born children with unilateral or bilateral cleft, born 2007-2013. A higher prevalence of unilateral and bilateral clefts (p<0.0001), as well as a predominance of male patients with unilateral clefts (p=0.0025), were identified among the internationally adopted children compared with children born in Sweden. Differences in the concurrence of other medical conditions in internationally adopted children versus Swedish-born infants were non-significant. Primary palatal surgeries performed in Sweden were significantly delayed for the adopted group. More secondary palatal surgeries such as speech improving surgery and palatal re-repair were needed for internationally adopted children (p<0.0001) until age five.Conclusions: The Swedish CLP Registry provided national coverage of the CL/P cohort. Internationally adopted children exhibited a predominance of more severe cleft types, a predominance of males, delayed primary palatal surgery and increased need for secondary surgeries before age five.

Diabetes in Young Adults : Remission, β-cell function and markers of inflammation
- 2003

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Type 1 diabetes is caused by immuno-mediated β-cell destruction leading to insulin deficiency and hyperglycaemia. The decline in β-cell function and the clinical course after diagnosis vary. Whether the process of destruction of the β-cells is associated with markers of a non-specific inflammatory response is unknown. The aims of these studies were to identify factors of importance for clinical remission (low insulin need and normoglycaemia) and long-term β-cell function and estimate the degree of non-inflammatory response in type 1 diabetes in young adults. Clinical remission and β-cell function eight years after diagnosis were assessed and related to clinical, biochemical and immunological variables at diagnosis, including islet autoantibodies [ICA, GADA, IA-2A]. Markers of low-grade inflammation in plasma [CRP and IL-6] were estimated and the concentrations were related β-cell function [plasma C-peptide], glycaemic control and autoimmunity at diagnosis and the first year thereafter. The results showed that clinical remission occurred in about half of the patients with newly diagnosed type 1 diabetes. Preserved β-cell function eight years after diagnosis was observed in 16% of the patients classified at diagnosis as having autoimmune type 1 diabetes. Duration of remission was dependent on BMI, degree of metabolic derangement and presence of GADA at diagnosis. BMI at diagnosis was also of importance for preserved β-cell function after eight years of the disease, as were the amount of islet antibodies and presence of ICA. Elevated CRP levels were noted in the majority of cases at diagnosis and both CRP and IL-6 concentrations were stable the first year after clinical diagnosis. High concentrations of CRP and IL-6 did not relate to β-cell destruction or the degree of autoimmunity. CRP concentrations were higher in islet antibody negative than in positive patients. CRP also correlated positively to BMI, C-peptide at 12 months and to increasing HbA1c between six and 12 months. In general, females had shorter remissions, lower concentrations of serum bicarbonate and higher levels and prevalence of GADA at diagnosis, compared to males. Females also had higher HbA1c and CRP values the first year after diagnosis. In summary, BMI at diagnosis is a strong predictor of duration of remission and preservation of β-cell function. Elevated CRP concentrations are correlated to factors linked rather to insulin resistance than to β-cell destruction. Females appear to have a more acute onset and a more severe course of the disease than males.

- OBJECTIVES:To describe the course of clinical remission in adult patients (16-50 years of age) with type 1 diabetes and to identify factors predictive of the occurrence and length of remission.DESIGN:A retrospective cohort study.SUBJECTS:Sixty-two consecutive patients (43 men and 19 women) with new onset IDDM, 27 +/- 8 years at diagnosis and treated with multiple insulin injections from the beginning.SETTING:Department of Medicine, Uppsala University Hospital and Orebro Medical Centre, Sweden.MAIN OUTCOME MEASURES:Length and occurrence of remission (defined as maintenance of HbA1c < or = 6.5% and an insulin dosage of < or = 0.4 U kg-1 day-1 for a minimum of 1 month) in relation to nine biochemical and clinical factors at diagnosis.RESULTS:Sixty-one per cent of the patients entered remission. The duration of remission was longer in males than females (10 +/- 12 vs. 2 +/- 3 months; P < 0.01). Male gender, normal serum bicarbonate at onset and a short time of classic symptoms before onset were predictive markers (P < 0.01; P < 0.05 and P < 0.01, respectively) for longer duration of remission. Low serum bicarbonate levels at onset were associated with lower occurrence of remission. Blood glucose, body mass index (BMI), and age at diagnosis did not influence the occurrence or the duration of remission.CONCLUSIONS:In most adult patients with new onset of type 1 diabetes remission is induced when using multiple insulin injection therapy. Male patients seem particularly prone to remission, and the length and extent of beta-cell strain prior to diagnosis strongly influences its course.

- ObjectivesTo establish the prevalence of remaining β-cell function 8 years after diagnosis of diabetes in young adults and relate the findings to islet antibodies at diagnosis and 8 years later.DesignPopulation-based cohort study.SettingNationwide from all Departments of Medicine and Endocrinology in Sweden.SubjectsA total of 312 young (15–34 years old) adults diagnosed with diabetes during 1987–88.Main outcome measurePlasma connecting peptide (C-peptide) 8 years after diagnosis. Preserved β-cell function was defined as measurable C-peptide levels. Three islet antibodies – cytoplasmic islet cell antibodies (ICA), glutamic acid decarboxylase antibodies and tyrosine phosphatase antibodies – were measured.ResultsAmongst 269 islet antibody positives (ab+) at diagnosis, preserved β-cell function was found in 16% (42/269) 8 years later and these patients had a higher body mass index (median 22.7 and 20.5 kg m−2, respectively; P = 0.0003), an increased frequency of one islet antibody (50 and 24%, respectively; P = 0.001), and a lower prevalence of ICA (55 and 6%, respectively; P = 0.007) at diagnosis compared with ab+ without remaining β-cell function. Amongst the 241 patients without detectable β-cell function at follow-up, 14 lacked islet antibodies, both at diagnosis and at follow-up.ConclusionsSixteen per cent of patients with autoimmune type 1 diabetes had remaining β-cell function 8 years after diagnosis whereas 5.8% with β-cell failure lacked islet autoimmunity, both at diagnosis and at follow-up.

- Aim To identify clinical, immunological and biochemical factors that predict remission, and its duration in a large cohort of young adults with Type 1 diabetes mellitus (DM).Methods In Sweden, 362 patients (15–34 years), classified as Type 1 DM were included in a prospective, nation-wide population-based study. All patients were followed at local hospitals for examination of HbA1c and insulin dosage over a median period after diagnosis of 5 years. Duration of remission, defined as an insulin maintenance dose ≤ 0.3 U/kg/24 h and HbA1c within the normal range, was analysed in relation to characteristics at diagnosis.Results Remissions were seen in 43% of the patients with a median duration of 8 months (range 1–73). Sixteen per cent had a remission with a duration > 12 months. Among patients with antibodies (ab+), bivariate analysis suggested that adult age, absence of low BMI, high plasma C-peptide concentrations, lack of ketonuria or ketoacidosis at diagnosis and low insulin dose at discharge from hospital were associated with a high possibility of achieving remission. Multiple regression showed that normal weight (BMI of 20–24.9 kg/m2) was the only factor that remained significant for the possibility of entering remission. In survival analysis among ab+ remitters, a low number of islet antibodies, one or two instead of three or four, were associated with a long duration of remissions.Conclusion In islet antibody-positive Type 1 DM, normal body weight was the strongest factor for entering remission, whilst a low number of islet antibodies was of importance for the duration.
