Screening of Congenital Hypothyroidism in North-East Romania. Benefits and Messages for Further ImprovementActa Endo (Buc) 2020 16(4): 437-442 doi: 10.4183/aeb.2020.437
AbstractBackground. If not diagnosed at birth, congenital hypothyroidism (CH) can cause deleterious, irreversible neurodevelopmental sequels. The importance of thyroid newborn screening (NBS) is therefore well established. Objective. To evaluate the efficacy of NBS for CH in North-East Romania. Methods. Retrospective, descriptive study involving 271662 newborns screened between 2010 and 2019 for CH and phenylketonuria in maternities from six Romanian NorthEastern counties by measuring neonatal TSH (neoTSH) in the whole blood extracted from the heel between days 3 and 5 after birth. Values found higher than a cut-off level of 10 mIU/L were followed by serum evaluation of TSH and fT4 for the confirmation of CH. Thyroid ultrasound was further performed at children found with CH. Results. NeoTSH was found elevated in 417 newborns, but CH was subsequently confirmed in only 57 cases (1/4766 newborns). Mean age at the time when diagnosis was communicated was of 37.2 ± 15 days (between 9 and 157 days). Mean age when therapy was started was of 44.2 ± 17.9 days (between 13 and 160 days) with a mean delay of one week from diagnosis (between 0 and 62 days). Thyroid ultrasound revealed athyreosis in only 3 cases, atrophic thyroid gland in other 10 cases, whereas the thyroid was described as present in the remnant 44 cases. The number of first year follow-up visits greatly varied from 0 to 5, with an average of 2. Conclusions. NBS allowed rapid diagnosis of CH in North East Romania. The communication of diagnosis to families and therapy onset were however often delayed. Diagnosis and therapy onset before the age of two weeks, as well as a tighter follow-up should be assured by the healthcare system. Etiological diagnosis should be more accurate, for a better prognosis of disease severity, as well as the possibility of genetic advice in selected cases. -

What Should Be the Approach to Moderate Hypocalcaemia in the Early Period Following Total ThyroidectomyActa Endo (Buc) 2017 13(4): 437-440 doi: 10.4183/aeb.2017.437
AbstractContext. It is unclear whether treatment is necessary for transient moderate hypocalcaemia occurring after total thyroidectomy; if it is present, it is unclear which treatment modality should be preferred. Objective. To investigate both the necessity and effectiveness of different treatment approaches of oral and/ or intravenous calcium treatment in patients with transient, postoperative, moderate hypocalcaemia. Design. This is a case control study made between June 2014 and June 2015. Subjects and Methods. Forty-five patients who had serum calcium levels 6 hours after total thyroidectomy between 7.5-8 mg/dL were divided into three equal groups: an oral calcium administration group, an intravenous calcium administration group and a no-treatment group. Serum calcium and parathyroid hormone levels were measured preoperatively and on postoperative days 1, 2, 5 and 10. Results. For post-thyroidectomy patients with serum calcium 7.5-8 mg/dL in the early postoperative period, no significant difference in serum calcium or parathyroid hormone was detected between groups. Conclusions. Follow-up without treatment seems to be the most effective approach for moderate hypocalcaemia occurring in the early period following total thyroidectomy; this suggests that intravenous treatment should be avoided. -

Predictive Value of Chromogranin A in a Diagnosis Towards Pheochromocytoma in Adrenal IncidentalomaActa Endo (Buc) 2016 12(4): 437-442 doi: 10.4183/aeb.2016.437
AbstractContext. Some adrenal tumors, such as pheochromocytoma, can be life-threatening. Therefore it is crucial to distinguish them from other lesions, especially prior to surgery. Chromogranin A (CgA) seems to potentially be a good marker for tumors of chromaffin origin. Objective. To assess the differentiating value of CgA in the diagnostic work-up of pheochromocytoma. Design. Retrospective study of operated patients with adrenal incidentaloma with lesions > 10 Hounsfield’s units (HU) on CT. Subjects and Methods. Thirty patients (11 males, 19 females; aged 61.5±21 years) were enrolled in the study. Patients using medications interfering with the assessment of CgA and metanephrines were excluded. Two groups were formed: those with pheochromocytoma (Ph, n=16) and those with non-pheochromocytoma (N-Ph, n=14) lesions. Data included radiological features of masses, serum CgA and 24-hour urine metanephrines (24 - HUM) concentrations. Results. No difference in 24-HUM level nor tumor size or density was found between groups Ph and N-Ph. Median serum CgA concentration was higher in Ph group compared to the N-Ph: 99.35 (68.12-172.73) vs. 52.92 (34.37-101.26) ng/mL, respectively (P=0.04). In Ph group, the size of the lesion correlated negatively with density (r= -0.53, P=0.042). No significant correlation in CgA, 24-HUM, density or size of the lesion was found. Performed curve receiver operating characteristic (ROC) showed AUC=0.7232 for CgA. Taking into account CgA serum value of ≤ 50 ng/mL (sensitivity: 93.75%, specificity: 50.00%, P=0.012), we proposed an algorithm for management of lesions > 10 HU on CT. Conclusion. CgA level ≤ 50 ng/mL might be useful in initial screening evidence for the exclusion of pheochromocytoma. It is crucial to eliminate factors interfering with the measurements. -

Usefulness of immunohistochemistry in the diagnosis of nodular thyroid diseaseActa Endo (Buc) 2007 3(4): 437-450 doi: 10.4183/aeb.2007.437
AbstractNodular thyroid disease (NTD) is represented by palpable thyroid nodules (solitary, multiple) and thyroid incidentalomas (identified by means of thyroid ultrasonography). The discussed entities carry the same risk of malignancy (about 5 %). The main objective in evaluating NTD is represented by the exclusion of malignancy by means of corroborated investigations, focused on the value of a panel of IHC markers.\r\nMaterial and methods. We included in the study 27 cases of NTD, evaluated by means of: clinical investigation, ultrasonography of the thyroid, cytological examination, morphological analysis and IHC. The used panel of IHC markers comprised: Ki-67, PCNA, CK 19 and c-erbB2 (DAKO LSAB method)\r\nResults. From the total of cases, 8 presented positivity with Ki-67 and 17 with PCNA. Regarding CK 19, the majority of PTC cases stained ++ and diffusely, but not papillary hyperplasia (focal positivity).c-erbB2 diffuse and intense positivity (+++) was noticed in PTC.The case with a follicular tumor of uncertain malignant potential stained weakly only with c-erbB2.\r\nConclusions. From the used panel of IHC markers, CK 19 presented the best value, being able to differentiate FVPTC from FTC and PTC from papillary hyperplasia. -

Sex difference and effects of gonadal hormones on thermal pain thershold in ratActa Endo (Buc) 2009 5(4): 437-445 doi: 10.4183/aeb.2009.437
AbstractVarious clinical and experimental studies indicate that gonadal hormones exert\r\nmodulatory effects on nociception and analgesia.\r\nThe aim of the present study was to investigate the role of gonadal hormones in the\r\nresponse by male and female rats to thermal nociceptive stimulation.\r\nMaterials and Methods. 7 week old albino (Wistar) rats were used in our study.\r\nAnimals were randomly divided into control, sham and ovariectomised or orchidectomised\r\ngroups. Thermal pain threshold was measured through tail immersion test before and 10, 20\r\nor 40 days after gonadectomy. The pain threshold was measured as the time required to elicit\r\na flick of the tail called analgesia time. Serum testosterone, estradiol, progesterone or\r\nprolactin levels were measured simultaneously.\r\nThe results showed that analgesia time was higher in female (5.11 min) than in male\r\n(4.93 min) intact animals (p<0.05) indicating sex difference in response to thermal\r\nnociception. Serum testosterone, estradiol or progesterone level as well as analgesia time\r\nwere not significantly reduced 10 days after gondectomy. In male animals, analgesia time\r\nwas significantly decreased (p<0.01) 20 or 40 days after orchidectomy (2.25 or 2.14 min,\r\nrespectively) compared with control rats (4.93 min). Serum testosterone concentration was\r\nsignificantly reduced (p<0.05) 20 or 40 days after orchidectomy (0.08 or 0.09 ng/mL,\r\nrespectively) compared with control serum testosterone level (2.14 ng/mL). In female rats,\r\nanalgesia time was significantly decreased (p<0.001) 20 or 40 days after ovariectomy (2.87\r\nor 2.66 min, respectively) compared with control rats (5.11 min). Serum estradiol\r\nconcentration was significantly reduced (p<0.001) 20 or 40 days after ovariectomy (3.17 or\r\n0.87 ng/mL, respectively) compared with control serum estradiol level (19.95 ng/ml). Serum\r\nprogesterone level was also decreased (p<0.001) 20 or 40 days after orchidectomy (5.27 or\r\n0.55 ng/mL, respectively) compared with control serum estradiol level (17.66 ng/mL).\r\nSerum prolactin level was not significantly enhanced during experiment indicating that there\r\nwas not heat stress influencing the procedure.\r\nConclusively, our findings clearly indicate that depletion of gonadal hormones 20 or 40 days\r\nafter gonadectomy modulates the pain-induced behavioral responses related to thermal nociception. -

Multidirectional Assessment of Bone Structure Including Radioisotopic Analysis in Perimenopausal WomenActa Endo (Buc) 2018 14(4): 439-446 doi: 10.4183/aeb.2018.439
AbstractObjective. In postmenopausal period, changes in bone turnover markers (BTM), vitamin D3, cytokines and parathyroid hormone (PTH) are frequently observed. The study was to assess bone mineral density (BMD) and bone metabolism index (IBM) in the perimenopausal women. Design years: 2013-2014. Subjects and Methods. One hundred and thirteen women were divided into four groups: group I (35 not menstruating 50 - 60 years old with osteoporosis), II (23 not menstruating 50 - 60 years old without osteoporosis), III (30 menstruating 40 - 49 years old with osteoporosis), IV (25 menstruating 40 - 49 years old without osteoporosis). The following parameters were measured: IL-1β, IL-6, TNF-α, hormone oestradiol (E2), PTH, FSH, TSH, calcium (Ca2+), phosphates (P), alkaline phosphatase (bALP), C-terminal telopeptide of type I collagen alpha 1 chain (α1CTX), osteocalcin (OC), BMD, IBM. Results. IBM and BMD were significantly lower in premenopausal than in postmenopausal women. The concentration of OC, CTX, 25OH D3 and PTH levels differed significantly between group I vs. II, group I vs. III and group II vs. IV. Conclusions. The levels of BTM, D3, PTH differed significantly between groups. This study demonstrated that bone metabolism depended mainly on processes related with menopause state and changes in D3, PTH and cytokines levels. -

Clinical TrialsActa Endo (Buc) 2013 9(3): 439-444 doi: 10.4183/aeb.2013.439
AbstractFrom the beginning of the new millenium, several trends are characteristic of clinical trials and reflect the dynamics of this area: from evidence-based approach to personalized medicine and pharmacogenomics, from translational medicine to new requirements of ethics and transparency of clinical trials, all these tendencies reflecting the current trends. In order to get enough statistical power, more and more patients are required; therefore a number of dedicated networks for specific disorders appeared. In addition, open access editorial policy is part of the information process both at the beginning (documentation) and at the end (dissemination) of any clinical trial. -

NOS3 RS1799983 and RS2070744 Polymorphisms and their Association with Advanced Chronic Kidney Disease and Coronary Heart Disease in Canarian Population with Type 2 DiabetesActa Endo (Buc) 2021 17(4): 440-448 doi: 10.4183/aeb.2021.440
AbstractContext. Different polymorphisms of the endothelial nitric oxide synthase gene (NOS3) have been related to diabetic kidney disease. Objective. To evaluate the association between advanced diabetic chronic kidney disease (ACKD) and the rs1799983 and rs2070744 poymorphisms of NOS3 in a population from the Gran Canaria island. Design. Cross-sectional case-control study. Subjects and methods. Polymorphisms were genotyped in 152 subjects with ACKD secondary to type 2 diabetes [estimated glomerular filtration rate (eGFR) <30 mL/min/1.73 m2], 110 subjects with type 2 diabetes for 20 or more years since diagnosis without ACKD (eGFR ≥45 mL/ min/1.73m2 and albumin/creatinine ratio <300 mg/g and/or 24-h urinary albumin excretion <300 mg) and 292 healthy controls. Association between both polymorphisms and established coronary heart disease (CHD) was also analyzed in both groups with diabetes. Results. A greater proportion of homozygous individuals for the risk allele C of rs2070744 was found among subjects with ACKD. Association between ACKD and rs2070744 was observed in a recessive genetic model, both for comparison to subjects with diabetes but no ACKD [OR 2.17 (95% CI: 1.17-4.00), p=0.014] and for comparison to healthy controls [OR 1.61 (1.03-2.52), p=0.036]. The frequency of the C allele was significantly higher among subjects with CHD, but only in the group with ACKD. No associations were found for rs1799983. Conclusions. NOS3 rs2070744 is associated with ACKD in population with type 2 diabetes from Gran Canaria. A link between this genetic variant and CHD in Canarian subjects with type 2 diabetes could be restricted to cases with ACKD.
