ACTA ENDOCRINOLOGICA (BUC)

Introduction. Our aim was to compare the effects of conventional diabetic diet with refined carbohydrate restricted diet on glycemic and metabolic parameters in type 2 diabetic patients who were treated by insulin.\r\nMaterials and methods. A hundred type 2 diabetic patients treated by insulin, randomized into two groups. The first group (n:50) was given a low refined carbohydrate\r\ndiet , the second group was given conventional diabetic diet. Metabolic parameters were evaluated at the beginning and at the end of the 3rd month of randomization.\r\nResults. There were no statistically significant weight change differences between groups (p=0,237). Changes in the HbA1C level (&#916; HbA1C) in the basal insulin-refined\r\ncarbohydrate restricted diet group, in the basal insulin-conventional diet group and in the premixed insulin-conventional diet group were -1.22% (p<0.001), -0.51% (p=0.13) and -0.66%(p=0.155), respectively. Symptomatic hypoglycemic episodes were reported only by the\r\npatients in premixed insulin group.\r\nConclusion. A diet rich in nutrients with sole exclusion of refined carbohydrates has been shown to be as effective as a stricter conventional diet and therefore it has to be\r\nconsidered as a preferable treatment option.

Context. Primary hyperparathyroidism is one of the most common endocrinological disorder and surgery of parathyroid glands is the main therapy of this disease. Minimally invasive surgery is getting more prominent in these days and its success in parathyroid surgery mostly depends on accuracy of the localization studies. Objective. The aim of this study is to understand the relationship between preoperative biochemical tests, intraoperative findings and Technetium-99mmethoxyisobutylisonitrile (MIBI) scan results. Design. Retrospective clinical study. Subjects and Methods. A total of 185 patients, who have been diagnosed with primary hyperparathyroidism (PHPT) and operated between January, 2010 and October, 2018, were included to the study. Patients with less than 6 months of follow up are excluded from the study. Results. Patients were divided into two groups according to their scintigraphy results; with positive scintigraphy findings as group 1 (n:135) and negative scintigraphy findings as group 2 (n:50). Mean preoperative serum parathyroid hormone (PTH) values were significantly different between the two groups (p<0.02). Mean preoperative serum calcium, creatinine, magnesium, phosphorus, alkaline phosphatase, 25-OH Vitamin D3 levels of both groups were analyzed and there were no statistical differences between the two groups considering these parameters. Also, mean diameter and mean volume of parathyroid adenomas were significantly higher in group 1 (2.1±1.0 cm vs. 1.55±0.72 cm, respectively, p<0.0001; 2.66±5.35 cm3 vs. 1±1.9 cm3, respectively, p<0.0001). Optimal cut-off values of parathyroid adenoma diameter for MIBI scan positivity were 1.55 cm, parathyroid volume for MIBI scan positivity were 0.48 cm3, preoperative serum PTH for MIBI scan positivity were 124.5 ng/L. Conclusions. Preoperative serum PTH levels, diameter and volume of adenomas might be helpful for the prediction of MIBI scan accuracy and possible need of another localization studies.

The discovery of the cannabinoid receptors CB1 and CB2 in 1990 and 1993, respectively, as well as of the two main endocannabinoids, anandamide in 1992 and 2-arachidonylglycerol in 1995, was an important step in identifying the strongest homeostatic system in the human body, namely the endocannabinoid system. Ever since, research has highlighted the crucial part played by this system in all the reproduction stages: folliculogenesis, spermatogenesis, oogenesis, fecundation, transport of the egg through the fallopian tubes, blastocyte implantation and pregnancy progression, as well as its implications in the physiopathology of the reproductive system: in endometriosis, ectopic pregnancy, miscarriage, preeclampsia, endometrial cancer, polycystic ovary syndrome, ovarian cancer. A special attention must be paid to the phytocannabinoids, natural components originating especially from the Cannabis plant inflorescences, whose medical effects are wellestablished nowadays with also acting on the receptors of the endocannabinoid system. The most recent research mainly focuses on the reproductive dysfunctions and disorders of the reproductive tissues, respectively, through its action upon the endocannabinoid system. Medical cannabis is nowadays legalized in more and more countries all over the world. At the same time, recreational cannabis remains one of the most consumed drugs (in Romania the most consumed one by young adults). Therefore, it is mandatory for specialists in obstetrics and gynecology, endocrinology, public health, hygiene or for general practitioners, to permanently update their information on this subject.

Aim is to evaluate atherosclerotic risk factors and carotid intima media thickness [CIMT] in offspring of type 2 Diabetes Mellitus [DM] patients with normal glucose tolerance. Methods. We evaluated 96 offspring of Type 2 DM patients and 39 healthy control who were in similar age, sex and body mass. We measured fasting blood glucose [FBG], postprandial blood glucose [PBG], insulin, uric acid, homocystein, fibrinogen, HOMA-IR, lipid profile, hsCRP, microalbuminuria, glycosylated hemoglobin A1c and CIMT by Doppler ultrasonography. Results. FBG was found higher in study group [p<0.001]. The HOMA-IR was 1.7±0.98 and 1.2±0.58 mg/dL x uUI/mL for study and control group, respectively [p=0.007]. TCholesterol, triglycerides, HDL-C, LDL-C and homocystein levels were not different. HsCRP and fibrinogen levels were higher in study group [p=0.014 and p=0.035, respectively]. Microalbuminuria levels were higher in study group but not significant [p=0.111]. CIMT in study group increased distinctively [p<0,001]. In regression analysis, being in study group causes a significant increase on the mean CIMT level by 0.057 mm [0.029-0.086] Conclusion. Our study demonstrated that various atherosclerotic risk factors are aggregated in offspring of Type 2 DM patients having NGT even before they develop glucose intolerance. Having a diabetic family alone might be effective in developing increased CIMT.

Objective. This research aim was to evaluates the role of the pre-ablation neutrophil-to-lymphocyte ratio (NLR) and lymphocyte-to-monocyte ratio (LMR) as predictors of distant metastases in patients with differentiated thyroid cancer (DTC). Methods. A retrospective analysis was given to 140 patients with DTC who received 131I remnant ablation after surgery. The patients were divided into two groups based on the existence of distant metastasis. Results. The two groups showed no significant difference in age, gender, WBCs, neutrophils, monocytes, eosinophils, basophils and whether the tumor was multifocal. In the univariate analysis, significant differences were found in tumor size (p=0.021), lymphocyte (p=0.012), NLR (p=0.027), and LMR (p=0.007). According to the ROC curves, NLR had an AUC of 0.612 ± 0.097 with a cut-off value of 1.845, sensitivity of 60.0%, and specificity of 66.2% (p=0.027). LMR had an AUC of 0.638 ± 0.095 with a cutoff value of 4.630, sensitivity of 84.6%, and specificity of 35.4% (p=0.007). In the multivariate analysis, larger tumor size (OR=5.246, 95% CI 1.269-10.907, p=0.009) and higher NLR (OR=2.087, 95% CI 0.977-4.459, p=0.034) were statistically significant for distant metastases. Conclusion. This research reveals that pre-ablation NLR and tumor size are significantly statistically correlated with distant metastases in patients with DTC.

Calciphylaxis, also known as calcific uremic arteriolopathy (CUA), is usually observed in women and it is a serious complication of hyperparathyroidism secondary to chronic renal failure. CUA is characterized by ischemic tissue loss secondary to progressive vascular degeneration. Although it is rare, it may end up with sepsis and organ failure and can be fatal. Its pathogenesis is not fully understood, but it is thought that it occurs secondary to increased calcification activators such as oxidized LDL, TNF- α, calcitriol, fibronectin, collagen-I, and TGF-1α. The most effective treatment is managing underlying pathology and decreasing serum calcium and phosphorus levels. In this report, we aimed to present an end stage renal failure case with coexisting hyperparathyroidism, hyperthyroidism and calciphylaxis in whom cutaneous manifestations were healed 6 months after parathyroidectomy.

Background. Idiopathic hypercalciuria is a risk factor for nephrolithiasis. Both renal stones and hypercalciuria are associated with lower bone mineral density (BMD), but the relationship between these modifications is not completely understood. Aims. To evaluate some metabolic particularities possibly related to relapsing nephrolithiasis (RN) in young male patients. Methods. We performed a crosssectional study including a group of 30 young male patients with RN and a group of 30 healthy, age and BMI (body mass index) matched controls (CTR). We evaluated calcium and phosphate metabolism, bone remodeling markers alkaline phosphatase (AP) and osteocalcin in serum and 24-hour urine samples, and lumbar and hip BMD. Results. We observed higher values of serum calcium (P<0.05) and 24 hour urinary calcium (P<0.001) in the RN group. Parathyroid hormone (PTH) and AP were also higher in the RN group (P<0.01), whereas serum 25OH-D3 was lower (P<0.01). BMD, T and Z scores were lower in the RN group in both the lumbar (P<0.01) and hip (P<0.05) regions. Conclusions. Young male patients with hypercalciuric RN have lower BMD and higher bone turnover. Higher PTH levels related to vitamin D deficiency may contribute to bone demineralization in certain cases.

Background. Mixed gonadal dysgenesis is a disorder of sex development associated with a numerical or sex chromosome abnormality. There is no association between the degree of mosaicism and the phenotype. Case report. An 11 years old girl was admitted for excessive weight [BMI: 31.55 kg/m2 (+ 3 SD)]. The family medical history was positive for overweight and obesity, type 2 diabetes mellitus, but no evidence of gonadal disorders or infertility was found. Physical examination revealed Turner Syndrome stigmata, acanthosis nigricans, excessive adipose tissue, normal female type external genitalia, Tanner pubertal stage 0. Even though the patient’s main complaint was the excessive weight, the most striking feature was the short stature. Further evaluation showed decreased IGF-1 level, delayed bone age, GH deficiency and Impaired Glucose Tolerance. The genetic analysis performed showed 45, X0 (20%)/ 46, XY (80%) karyotype with positive SRY gene. The histopathological examination of bilateral gonad biopsy confirmed the presence of ovarian hypoplastic tissue in the left gonad and ovarian tissue suggesting gonadoblastoma of the right gonad. Conclusion. Correct diagnosis and management of these patients needs a multidisciplinary team effort. The benefit of GH treatment therapy was demonstrated in the majority of 45, X0 / 46, XY short stature patients.

Context. Spontaneous muscle infarction is a rare complication of diabetes mellitus, mainly affecting women and patients with long-lasting type 1 diabetes. Objective. This report is aimed to describe the case of a patient with type 1 diabetes and diabetic nephropathy in whom a severe deterioration of renal function was triggered by a muscle infarction. Subject and Methods. Subject of the study was a 33-years-old woman with an 18 years history of type 1 diabetes mellitus, proliferative diabetic retinopathy, nephropathy at stage 3 chronic kidney disease, somatic sensory-motor polyneuropathy and autonomic neuropathy. Results. The patient presented with severe pain and dysfunction of the left thigh without prior trauma plus progressive deterioration of the renal function. Nuclear magnetic resonance of the thigh showed inflammatory changes in the external vastus with hyperintensity on T2 sequence and edema of the subcutaneous cellular tissue. After other possible etiologies were ruled out, a clinical diagnosis of spontaneous muscle infarction was established. The patient needed hospital admission for two months, during which the renal function worsened until she required hemodialysis. No other possible triggers of kidney injury were identified. Conclusions. Up to our knowledge, this is the first described case where muscle infarction is suspected to have caused exacerbation of an existing chronic kidney failure. Monitoring the renal function should be considered in patients with diabetic nephropathy presenting with this rare complication of diabetes.

Atherosclerotic Cardiovascular Diseases are the leading cause of death worldwide. Aim. To estimate the prevalence of cardiovascular risk (CVR) categories in the adult population (aged 40-79 years) of Romania. Design. The present study was part of the epidemiological, cross-sectional PREDATORR study (PREvalence of DiAbeTes mellitus, prediabetes, overweight, Obesity, dyslipidemia, hyperuricemia and chronic kidney disease in Romania). Subjects and Methods. Exclusion criteria: age <40/ or>79 years old and diagnosis of ischemic vascular disease. The CVR was evaluated using charts developed by the World Health Organization/ International Society of Hypertension (WHO/ISH) available for Europe B (epidemiological subregion where Romania was included). The CVR was divided into 5 categories: <10%, 10-20%, 20-30%, 30-40%, > 40%. Results. A total of 1631 subjects (57.0±10.7 years, 45.1% males) were included in the present study. The age and sex-adjusted prevalence of CVR >40% was 2.9% (95%CI 2.8-3.1%), CVR 30-40% was 1.85% (95%CI 1.8-1.9%), CVR 20-30% was 5.8% (95%CI 5.6- 6.0%) and 13.0% (95%CI 12.8-13.3%) of the adult Romanian population has a 10-20% CVR, these CVR categories being more frequent in male and older age. Diabetes, overweight/ obesity and smoking were associated with high CVR categories. Conclusion. Romania is one of the countries with high CVR, requiring CVD prevention measures.
