Background: Premature aging are frequently observed among individuals with type 1 diabetes. Decrease of ovarian reserve may be one of the characteristics of such process. Aims: To evaluate the ovarian reserve function in female patients of reproductive age with type 1 diabetes in comparison with healthy women. Materials and methods: This study evaluated 224 Caucasian women, age 1837 years with type 1 diabetes and 230 healthy women of comparable age. Serum concentrations of anti-Mullerian hormone (AMH), inhibin B, follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone and testosterone were compared on the 23 day of menstrual cycle as ovarian volume and antral follicle count (AFC). In addition, glycated hemoglobin level (HbA1c%) was evaluated. Results: We reveal statistically significant difference in following parameters in diabetic women in comparison with healthy women: AMH, AFC. But even in diabetic patients parameters remained within reference ranges. There was a pronounced negative relationship between the levels of HbA1c% and AMG. Conclusions: Ovarian reserve function parameters decrease in young women with type 1 diabetes in comparison with healthy women, but ovarian reserve parameters are in normal reference range. These findings are important in pregnancy planning consulting by gynecologists and endocrinologists. We must recommend to women with type 1 diabetes more early planning of natural pregnancy for treatment with reproductive technology in cases of prolog absence of nature pregnancy.

The reproductive potential of a woman depends on indicators of the ovarian reserve, such as the anti-Muller hormone (AMH) and the number of antral follicles (NAF). Autoimmune diseases have a significant effect on fertility and contribute to the development of premature ovarian failure. Aim.To evaluate the parameters of the ovarian reserve in patients with type 1 diabetes mellitus, carriers of antibodies to the thyroid gland in a state of euthyroidism and compare them with similar parameters in healthy women. Materials and methods.In the first block of the study, the level of AMH, follicle-stimulating hormone, luteinizing hormone, NAF was studied among 224 women with diabetes and 230 healthy women in the control group. In block II, the level of the above hormonal indices was studied in 35 carriers of antithyroid antibodies in the state of euthyroidism and 35 healthy women. Results.In patients with type 1 diabetes, the level of AMH, NAF was statistically significantly lower when compared with the control group. Among carriers of antithyroid antibodies and healthy women, no difference in AMH and NAF was found. Conclusion.The autoimmune processes accompanying diabetes are more influenced by the ovarian reserve indices than autoimmune aggression to the tissues of the thyroid gland.

BACKGROUND: One of the consequences of obesity for the female body is a decrease in fertility. It is shown that impaired reproductive function in obese patients can be associated, in particular, with a decrease in ovarian reserve. AIMS: To evaluate the ovarian reserve function in female patients of reproductive age with different classes of obesity in comparison with women without obesity. MATERIALS AND METHODS: This study evaluated 320 caucasian women, age 20-30 years, without obesity (BMI30, n=80) and with obesity WHO class I-III (n=80 per class). Anthropometrics, serum concentrations of anti-Mullerian hormone (AMH), inhibin B, follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, and testosterone were compared on the 2-3 day of menstrual cycle as ovarian volume and antral follicle count (AFC). RESULTS: We reveal statistically significant difference in following parameters in normal BMI women in comparison with obesity women: AMH, testosterone, ovarian volume and AFC. Moreover, we reveal significant difference between patients with different WHO class of obesity. But even in class III obesity parameters remained within reference ranges. CONCLUSIONS: Ovarian reserve function parameters progressively decrease with increase of obesity class in subjects, but ovarian reserve parameters were in normal reference range even in class III obese patients. Further large randomized multicenter studies are required to find influence of obesity in relation to ethnicity and other factors to ovarian reserve function.

OBJECTIVE: Type 1 diabetes mellitus is frequently associated with autoimmune thyroid disease (ATD). Genetic susceptibility to autoantibody formation in association with ATD and type 1 diabetes mellitus has been described with varying frequencies, but there is still debate about the situation in the Chinese population. We have, therefore, investigated the prevalence of anti-thyroid peroxidase (anti-TPO) in type 1 diabetic patients, and compared the effect of anti-glutamate decarboxylase (anti-GAD) on the thyroid autoimmunity in patients with type 1 diabetes mellitus in Taiwan. SUBJECTS AND METHODS: Two hundred and forty-three subjects with type 1 diabetes mellitus and seventy unrelated normal controls were recruited for the detection of anti-TPO. Two hundred and seventeen sera from two hundred and forty-three type 1 diabetic patients were tested for anti-GAD. RIA and immunoprecipitation were used for anti-TPO and anti-GAD detection respectively. RESULTS: The intra-assay and interassay coefficients of variation of anti-TPO detected by the RIA method ranged from 5.5% to 11.1%. Among 243 type 1 diabetic patients, 53 (21.8%) were positive for anti-TPO. Compared with those without thyroid autoimmunity, there was a female preponderance for the type 1 diabetic patients with thyroid autoimmunity (female:male, 99:91 vs 37:16 respectively). Among the type 1 diabetic patients with thyroid autoimmunity, anti-TPO tended to occur in those of older age or with long-standing disease. The frequency of anti-GAD was 45.6%, (99 of 217), without gender preponderance (males:females, 18.0% vs 27.61%). Compared with those with negative anti-GAD, no significant difference of anti-TPO positivity for the type 1 diabetic patients with positive anti-GAD was found. CONCLUSION: Our data indicated that the RIA method for anti-TPO detection is sensitive and precise for routine clinical use. The presence of anti-TPO in 21.8% of our type 1 diabetic patients confirmed the strong association of ATD and type 1 diabetes mellitus without ethnic differences. The absence of correlation between anti-TPO and anti-GAD in our type 1 diabetic patients suggested genetic heterogeneity in the role of autoimmunity of type 1 diabetes mellitus and ATD among races.

The Impact

Background Higher 25(OH)D3 levels are associated with lower HbA1c, but there are limited UK interventional trials assessing the effect of cholecalciferol on HbA1c. Aims (1) To assess the baseline 25(OH)D3 status in a Manchester cohort of children with type 1 diabetes (T1D). (2) To determine the effect of cholecalciferol administration on HbA1c. Methods Children with T1D attending routine clinic appointments over three months in late winter/early spring had blood samples taken with consent. Participants with a 25(OH)D3 level <50 nmol/L were treated with a one-off cholecalciferol dose of 100,000 (2–10 years) or 160,000 (>10 years) units. HbA1c levels before and after treatment were recorded. Results Vitamin D levels were obtained from 51 children. 35 were Caucasian, 11 South Asian and 5 from other ethnic groups. 42 were vitamin D deficient, but 2 were excluded from the analysis. All South Asian children were vitamin D deficient, with mean 25(OH)D3 of 28 nmol/L. In Caucasians, there was a negative relationship between baseline 25(OH)D3 level and HbA1c (r = −0.484, P < 0.01). In treated participants, there was no significant difference in mean HbA1c at 3 months (t = 1.010, P = 0.328) or at 1 year (t = −1.173, P = 0.248) before and after treatment. One-way ANCOVA, controlling for age, gender, ethnicity, BMI and diabetes duration showed no difference in Δ HbA1c level. Conclusion We report important findings at baseline, but in children treated with a stat dose of cholecalciferol, there was no effect on HbA1c. Further studies with larger sample sizes and using maintenance therapy are required.

AbstractBackground:Enteroviral infections have long been suspected in having a role in β cell destruction and therefore leading to the onset of clinical type 1 diabetes (T1D). The frequency of enterovirus (EV)-related T1D in North Africa is still unknown. The aim of the present study was to investigate the relationship between infection with EV and T1D in Tunisia.Methods:A total of 95 T1D patients (41 children and 54 adults) and 141 healthy control subjects (57 children and 84 adults) were tested for the presence of EV-RNA by a highly sensitive nested reverse transcription-polymerase chain reaction (RT-PCR) method.Results:EV-RNA was detected more frequently in plasma from diabetic patients than in plasma of controls (31.6% vs. 7.8%, p<0.0001; OR=5.45; 95% CI 2.44–12.43). RT-PCR revealed positive in 53.7% of T1D children and 14.8% of T1D adults. There was a statistically significant difference between children and adults with T1D (p<0.0001). Positivity of EV-RNA according to the time after the occurrence of the disease did not show any significant difference (p=0.34). Anti-glutamic acid decarboxylase (GAD) antibodies were not associated with EV-RNA (p=0.65).Conclusions:EV-RNA is associated with T1D mellitus in the Tunisian population especially in children. These results support the hypothesis that EV act as environmental risk factors for T1D.

Abstract Background Type 1 diabetes mellitus (T1D) results from environmental and genetic factors. We aimed to investigate the distribution of PTPN22, IL2RA rs11594656, and rs2104286 variants and its association with T1D in children. A case-control study conducted on 100 diabetic patients and 100 control children. PTPN22 gene, IL2RA rs11594656, and rs2104286 polymorphisms study were done by PCR followed by restriction fragment length polymorphism (RFLP) assay. Results T allele of PTPN22 gene was presented more frequently 47% in patient group versus 30% in controls, while C allele was 53% in the diabetic group versus 70% in controls showing a statistically significant difference between patient and control groups. Similarly, TT 1858 genotype was found in higher frequency with a statistically significant difference in favor of T1D patients (p = 0.038), OR (CI 95% 3.16 (1.28–7.09). For IL2RA rs11594656 polymorphism, the frequency of TT, TA, and AA in patients at percentages of 20%, 60%, and 20% versus 4%, 60%, and 36% in controls respectively showed significant difference (p = 0.045). Also, T allele was detected more in patients group as evidenced by p = 0.059, OR (95% CI) of 2.38(1.49–6.12). Whereas, IL2RA rs2104286 polymorphism revealed a difference of otherwise non-statistical significance (p = 0.091). Those who harbored homozygous pattern of both IL2RA polymorphisms frequently had DKA and high mean HbA1C values. Conclusion PTPN22 (C1858T) and IL2RA rs11594656 polymorphisms increased the risk of T1DM development, while IL2RA rs2104286 polymorphism did not display any significant association among children with T1D. Having more than one risk allele could affect progression and control of T1D.

Background: We aimed to assess Vitamin D levels in patients with Type 1 Diabetes (T1D) and to investigate the correlation between vitamin D and metabolic imbalance. Material and Methods: For our study, we selected thirty-one patients with T1D without complications and fifty-seven healthy controls. Diabetic patients were diagnosed using the criteria of the World Health Organization/American Diabetes Association. Vitamin D, Parathyroid Hormone (PTH), insulin and C peptide assay were performed using chimilunescence. Glucose level, lipid profile, glycated haemoglobin (HbA1c) and ionogram were also analysed. Results: Vitamin D, HbA1c and Gly levels were found to be significant in T1D patients than in controls (P<0.5). However, for PTH, no significant difference was observed (P > 0. 05) and the results show a non-significant difference of total cholesterol potassium, sodium, phosphor and calcium concentration averages. Conclusion: Our results indicate that the deficiency of VD is associated with an increased risk of T1DM in Algerian population.

Background & Objective: Type-1 diabetics (T1D) usually do not meet guidelines for glycaemic control. This study aimed to determine the benefit of free style libre-flash glucose monitoring system (FSL-FGM) in lowering glycated hemoglobin (HbA1c) in poorly controlled T1D patients. Methods: This prospective two single arm clinical study included 273 T1D patients, and data collected at one, six and 18 months with concomitant extraction of samples for HbA1c basal and at six and 18 months. The study was conducted in Prince Mansour Military Hospital at Taif, Saudi Arabia from June 2017 to November 2018. Results: HbA1c % was significantly diminished in patients used FSL-FGM at 6 and 18 months. The median percentage difference in HbA1c at 6 and 18 months versus basal was significantly decreased in those using FSL-FGM. Within diabetics using FSL-FGM, the median difference in HbA1c after 18 months was significantly decreased in patients with HbA1c >10% compared to those with HbA1c <10%. Estimated HbA1c by FSL showed a significant correlation with HbA1C assayed in the blood. The snapshot information showed a highly significant difference in average glucose with low significant difference in hypoglycemia parameters. The FSL-FGM provides significant changes in HbA1c in diabetic patients without observed risk for hypoglycemia. Conclusions: The dynamic way of blood glucose monitoring using FSL-FGM provides improvement in HbA1c in diabetic patients without observed risk for hypoglycemia. doi: https://doi.org/10.12669/pjms.37.7.4114 How to cite this:Mohamed IAA, Talaat IM, Alghamdi HA, Allam G.

Abstract This study aimed to explore differences in vascular and structural parameters using optical coherence tomography angiography in patients with type 1 diabetes (DM1) with mild signs of diabetic retinopathy (DR) over a two-year follow-up period. Parafoveal vessel density (PVD) and foveal avascular zone (FAZ) area were analyzed. The thickness of three predefined retinal slabs was measured, including the inner limiting membrane (ILM)–inner plexiform layer (IPL), IPL–inner nuclear layer (INL), and the IPL–outer nuclear layer (ONL). Twenty-two patients with DM1 and 21 controls were included. There was no significant difference in the FAZ area, perimeter and acircularity index between cohorts over time. Baseline superficial capillary plexus PVD was approximately 10% lower in patients with diabetes than in controls (p = 0.001), and was 12% lower at 2 years (p = 0.002). There was no difference in the annual linear trend between the groups (− 0.5% in diabetics vs. controls, p = 0.736). Baseline deep capillary plexus (DCP) PVD was slightly lower in diabetics than in controls (− 4.4%, p = 0.047) and the difference increased at 2 years (− 12.6%, p < 0.001). The annual linear trend was − 2.7% in diabetic patients compared to controls (p = 0.009). In addition, the PVD of the DCP and the intermediate capillary plexus (ICP) were evaluated separately. Regarding the DCP PVD, no statistically significant difference at any time points in diabetic patients compared to controls and no statistically significant difference in the linear trend was found (p > 0.1). Conversely, no difference was recorded for parafoveal ICP density at individual time points (p > 0.1), but a statistically significant difference in the linear trend over time in diabetic patients compared to controls was recoded (− 3.2% per year, p = 0.001). Despite the apparent intergroup differences at baseline in structural OCT parameters, the differences including ILM–IPL (p = 0.273), IPL–INL (p = 0.708), and IPL–ONL (p = 0.054) were modest and not statistically significant with time. Therefore, the microvascular change of the deeper vessels might be a robust biomarker to evaluate the clinical progression of DR in DM1.
