Association of Dipeptidiyl Peptidase-4 Inhibitors and Bullose Pemphigoid: A Report of Four Cases.

Dipeptidyl-peptidase 4 inhibitors (DPP4i) are commonly used as antidiabetic medications. Although these drugs are generally recognized for their favorable clinical safety profile, emerging evidence points to the potential for adverse events associated with DPP4i. Notably, cases of bullous pemphigoid (BP) linked to DPP4i therapy have recently been documented in the medical literature. This report presents four cases of BP in elderly patients resulting from DPP4i treatment, involving two cases with ligandliptin and two with vildagliptin use. Successful remission was achieved in all cases through discontinuation of the implicated medication and implementation of topical corticosteroid therapy. It is imperative for clinicians to be vigilant about the potential risk of BP development when employing DPP4i drugs, particularly in the context of elderly patients with diabetes.

Correlation of serum leptin and ghrelin levels with endocrine and reproductive parameters in women with clomiphene citrate resistant polycystic ovary syndrome.

Objective: To investigate the changes in serum ghrelin and leptin levels in patients with clomiphene-resistant polycystic ovary syndrome (PCOS). Materials and Methods: Thirty-five patients who could not achieve ovulation or pregnancy despite using 150 mg/day of clomiphene citrate (CC) participated in the study. Thirty-five patients who were compatible with the study group in terms of age and body mass index (BMI) but did not have clinical and laboratory findings of PCOS constituted the control group. On the third day of the cycle, in addition to the basal hormone profile, ghrelin and leptin levels were also measured. Patients in both groups went to IVF/ICSI. Basal hormone values, leptin, ghrelin, metabolic, demographic parameters, and clinical pregnancy rates were correlated. Results: Patients in both groups were recorded to be similar in terms of age (29.4±0.11 vs 28.5±7.30), BMI (24.3±3.07 vs 23.8±1.55), and infertility time (6.14±4.30 vs 6.03±1.28). Serum ghrelin levels of the PCOS group were significantly lower than the control group (0.48±2.21 vs 1.19±4.02) Serum leptin levels of the PCOS group were significantly higher than the control patients (45.6±304 vs 16.5±0.32). Serum leptin levels and BMI (r=0.65, p<0.01) A positive correlation was found between luteinizing hormone (LH) (r=0.53, p<0.02), and insulin resistance (r=0.74, p<0.03). There was a negative (r=-0.76, p<0.03) correlation between serum ghrelin and LH. A positive and significant correlation was found between serum ghrelin, testosterone, mature oocyte, and implantation rates. Conclusion: Serum ghrelin correlates with fertility outcomes in women with CC-resistant PCOS undergoing IVF/ICSI.

Status of Weight Change, Lifestyle Behaviors, Depression, Anxiety, and Diabetes Mellitus in a Cohort with Obesity during the COVID-19 Lockdown: Turk-Com Study Group.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic led to a lockdown period. Confinement periods have been related to unhealthy lifestyle behaviors. Our study aimed to determine weight change, changes in eating and exercise habits, the presence of depression and anxiety, and diabetes mellitus (DM) status in a cohort of patients with obesity. METHODS: The study was undertaken in nine centers of Collaborative Obesity Management (COM) of the European Association for the Study of Obesity (EASO) in Turkey. An e-survey about weight change, eating habits, physical activity status, DM status, depression, and anxiety was completed by patients. The International Physical Activity Questionnaire (IPAQ) score was used to determine physical activity in terms of metabolic equivalents (METs). A healthy nutrition coefficient was calculated from the different categories of food consumption. The Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder (GAD-7) Questionnaire  were used for determining depression and anxiety, respectively. RESULTS: Four hundred twenty-two patients (age 45 ± 12.7 years, W/M = 350/72) were included. The healthy nutrition coefficient before the pandemic was 38.9 ± 6.2 and decreased to 38.1 ± 6.4 during the pandemic (p < 0.001). Two hundred twenty-nine (54.8%) patients gained weight, 54 (12.9%) were weight neutral, and 135 (32.3%) lost weight. Patients in the weight loss group had higher MET scores and higher healthy nutrition coefficients compared with the weight gain and weight-neutral groups (p < 0.001). The PHQ and GAD scores were not different between the groups. Percent weight loss was related to healthy nutrition coefficient (CI: 0.884 [0.821-0.951], p = 0.001) and MET categories (CI: 0.408 [0.222-0.748], p = 0.004). One hundred seventy patients had DM. Considering glycemic control, only 12 (8.4%) had fasting blood glucose <100 mg/dL and 36 (25.2%) had postprandial BG <160 mg/dL. When patients with and without DM were compared in terms of dietary compliance, MET category, weight loss status, PHQ-9 scores, and GAD-7 scores, only MET categories were different; 29 (11.7%) of patients in the nondiabetic group were in the highly active group compared with 5 (2.9%) in the diabetic group. CONCLUSION: The COVID-19 lockdown resulted in weight gain in about half of our patients, which was related to changes in physical activity and eating habits. Patients with DM who had moderate glycemic control were similar to the general population in terms of weight loss but were less active.

Ovarian drilling down-regulates endometrial nuclear factor-κB p65 expression in women with PCOS: A prospective case-control study.

Objective: To investigate the impact of laparoscopic ovarian drilling (LOD) on the expression of endometrial NFκB p65 (Rel A) in women with clomiphene-resistant polycystic ovary syndrome (PCOS). Materials and Methods: The study group comprised 25 normal-weight women with PCOS undergoing LOD and 14 control women without PCOS. Endometrial NF-κB p65 levels evaluated before and after LOD following immunohistochemical staining. The semiquantitative method was used to evaluate the intensity of NF-κB p65 levels. NF-κB p65 was found to higher in the endometrium of patients with PCOS compared to controls. LOD leads to significant down-regulation in endometrial NF-κB p65 expression. NF-κB p65 expression of PCOS and fertile control were similar after LOD. After LOD, H-score values decreased approximately 3-fold. The H-score of the control subjects was lower than the preoperative and postoperative H-score values of the control women with ovarian cyst. Results: Expression of endometrial NF-κB p65 did not change following ovarian cystectomy. The laterality of the ovarian cyst did not cause any change in preoperative H-score values. Conclusion: By downregulating the endometrial NF-κB p65 expression LOD improved physiological inflammation in women with PCOS.

Ovarian stimulation drugs alter the metabolite content of the growing follicle: in vivo spectroscopic evaluation of follicle fluid

Objective: To determine and compare metabolite content using magnetic resonance spectroscopy (MRS) of growing follicles in patients with polycystic ovary syndrome (PCOS) receiving recombinant follicle stimulating hormone (rFSH), clomiphene citrate (CC) or aromatase inhibitor (AI) for ovarian stimulation. Material and Methods: Thirty patients diagnosed with PCOS and infertility and scheduled for ovarian stimulation were divided by therapy, rFSH/CC/AI, into three equal groups. Five fertile cases were designated as the control group. When the follicle diameters reached 16-18 mm in each group, patients underwent MRS and the metabolite content of a dominant follicle was analyzed. N-acetylaspartate, lactate (Lac), creatine (Cr), and choline (Cho) metabolite levels in parts per million were measured in the spectra. Results: A ~three-fold decrease in dominant follicle Cho content was found in patients receiving CC compared to control subjects. Similarly, the dominant follicle Cho intensities of patients given rFSH and AI were noted to be significantly higher than those who received CC. Only dominant follicle Lac levels of the patients who received CC were found to be significantly higher than the other groups. Cr peak intensities of patients receiving CC were found to be approximately three times less than control subjects. Cr signal intensity was significantly higher in patients receiving rFSH or AI than in patients receiving CC. While two patients became pregnant in the CC group, three patients in the AI group and five patients in the rFSH group became pregnant. The main metabolites detected in patients who conceived in each group were Cho and Cr. In cases who could not conceive, while Lac and lipid signals increased, Cho and Cr signals decreased. Conclusion: Unlike CC, ovarian stimulation with rFSH or AI does not alter dominant follicle metabolite content. The developmental capacity of a growing egg may be determined non-invasively with MRS.

Antithyroid antibodies may predict serum beta HCG levels and biochemical pregnancy losses in euthyroid women with IVF single embryo transfer.

OBJECTIVE: To investigate the relationship between thyroid autoimmunity and early pregnancy serum ß-HCG levels in intracytoplasmic sperm injection patients. METHODS: The study subjects were 85 female euthyroid patients undergoing intracytoplasmic sperm injection embryo transfer cycles with GnRH antagonist treatment. Patients who received transfer of more than one embryo, those with serum TSH levels of greater than 2.5 IU/ml and subjects using levothyroxine were excluded. Normal responder patients under the age of 40 years were randomly selected from the patient files retrospectively. Subjects were divided into two groups: those with autoimmune thyroid disease (thyroid autoimmunity group; n = 39) and those without the disease (control group; n = 46). RESULTS: The age, body mass index, trial number, total rFSH treatment dose, the number of cumulus oophorus complexes, number of metaphase II oocytes, and number of 2-pronuclei embryos were similar in the thyroid autoimmunity and control groups. Serum ß-HCG levels measured on the 14th day after oocyte pickup were significantly lower in the thyroid autoimmunity group than in the control group (93.8 ± 35.8 versus 128.5 ± 55.8 mlU/ml, respectively; p < .001). The miscarriage rate was higher in the thyroid autoimmunity group than in the control group (34.4% versus 21.7%, respectively; p = .034). CONCLUSION: We found that early-stage pregnancy serum ß-HCG hormone levels among euthyroid patients undergoing intracytoplasmic sperm injection were lower in subjects with thyroid autoimmunity than in those without thyroid autoimmunity. This result, reported for the first time in the literature on euthyroid pregnant women with thyroid autoimmunity, may be predictor of early pregnancy losses in pregnant women with thyroid autoimmunity.Key messageIn intracytoplasmic sperm injection (ICSI)/IVF patients, due to lack of evidence-based data about the relationship between thyroid autoimmunity and pregnancy loss the current research was conducted. Early-stage pregnancy serum ß-HCG hormone levels in euthyroid ICSI patients with thyroid autoimmunity are lower than those without autoimmunity which may be associated with early pregnancy losses.

Effect of vitamin D status on lipid profile in premenopausal women: a cross-sectional study.

High lipid levels play important roles in the pathogenesis of atherosclerosis and some authors suggest vitamin D deficiency as a risk factor for atherosclerosis. The aim of this study was to evaluate the effect of vitamin D status on lipid profile in premenopausal women. PATIENTS AND METHODS: A total of 315 nonsmoking premenopausal female volunteers without diabetes mellitus were included in the study. Patients were divided into four subgroups. The groups were as follows: patients with less than or equal to 12 ng/ml (group 1, n=126) vitamin D levels, between 20 and 12 ng/ml (group 2, n=48), between 30 and 20 ng/ml (group 3, n=21), and at least 30 ng/ml (group 4, n=120) vitamin D levels. Total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), and non-HDL-C levels of the four groups were compared. RESULTS: HDL-C levels of group 4 were the highest (P=0.03), and TG and non-HDL-C levels of group 1 were the highest (P=0.04, 0.016, respectively) in all groups. There was no significant difference between serum parathormone, calcium, and phosphorus levels of the four groups (P=0.778, 0.121, 0.184, respectively). In unadjusted analysis, 25-hydroxy vitamin D levels were found to be correlated negatively with BMI (P=0.0005), LDL-C (P=0.01), and non-HDL-C (P=0.003) and correlated positively with HDL-C levels (P=0.006). After adjustments for age, sex, BMI, and log parathormone levels were made, no correlation was found between 25-hydroxy vitamin D and lipid (TC, LDL-C, HDL-C, and TG) levels (P=0.91, 0.06, 0.95, 0.79, respectively). CONCLUSION: There may be an association between vitamin D insufficiency and dyslipidemia. However, this association may depend on obesity.

The goiter prevalence and urinary iodine levels among adolescents.

Endemic goiter and iodine deficiency are among the worldwide major public health problems of today. We aimed to research the goiter prevalence and the urinary iodine level of school children. In this descriptive study, 1,847 school children in Konya aged between 10 and 18 years were included. Urinary iodine level was measured. The mean value of iodine excretion in urine was 198 +/- 46.61 microg/L. In 40 students (2.2%), the urinary iodine level was < 100 microg/L. Six of these students (0.3%) had moderate iodine deficiency. Thyroid hyperplasia was found with palpation method in 128 students (6.9%). Ultrasonographically, five female students had solid nodule, and one male student had multiple nodules. In our study, no severe iodine deficiency was found. According to the results of our study, the mandatory iodization program in Konya has been conducted successfully.

Severe anaphylactic reaction to human insulin in a diabetic patient.

A 46-year-old nonatopic woman who had been suffering from type 2 diabetes for 17 years was hospitalized at the Endocrinology Department of Selcuk University due to very high glucose levels after recovery from acute hepatitis A infection. She had never used insulin before. After first subcutaneous dose of human regular insulin, severe local allergic reaction developed. Desensitization to insulin was tried. One day later, ketoacidosis developed. Human regular insulin was again subcutaneously injected to the patient. Severe anaphylactic reaction occurred, and in spite of all the medical attempts to save the patient, she died.

Assessment of anxiety in subclinical thyroid disorders.

It is well known that manifest thyroid dysfunction causes mood disorders. In the literature there are few studies related with subclinical thyroid dysfunction and anxiety. We aimed to determine if there exists a relation between the anxiety and subclinical thyroid dysfunction. This study was carried out in the Meram Medical Faculty of Selçuk University, Department of Endocrinology and Metabolism. Eighty-five outpatients were enrolled into the study. In the presence of normal fT(3) and fT(4), patients were grouped as subclinical hyperthyroid with TSH lower than 0.1 mU/L (n = 24), subclinical hypothyroid with TSH higher than 4.5 mU/L (n = 32) and euthyroid subjects (n = 29). Beck's Anxiety Inventory (BAI) was administered to all patients. There was no any statistically significant difference between euthyroid and study groups in terms of age, gender, weight and height (p<0.05). One-way ANOVA showed that both of the subclinical hypothyroid and subclinical hyperthyroid groups had significantly higher anxiety scores than euthyroid group (F: 11.4, p<0.001). Manifest hypothyroidism and hyperthyroidism, as causes of mental and neurological dysfunction have been known for a long time, but the relation between subclinical thyroid dysfunction and anxiety is less well studied. We have found that subclinical thyroid dysfunction increases the anxiety of patients whether hyperthyroid or hypothyroid. Overlap of symptoms common to both thyroid dysfunction and anxiety is an important limitation in this study. Mood changes especially anxiety due to subclinical thyroid dysfunction may have an important impact on the patient's quality of life. Negative effect on quality of life may be an indication of treatment in these patients. It is the first study evaluating anxiety in subclinical hypothyroidism in the literature.
