Body Composition Changes in Men With HIV/HCV Coinfection, HIV Monoinfection, and HCV MonoinfectionActa Endo (Buc) 2022 18(4): 442-451 doi: 10.4183/aeb.2022.442
AbstractContext. Both human immunodeficiency virus (HIV) infection and hepatitis C virus (HCV) infection represent systemic diseases that may develop metabolic complications, thus HIV/HCV coinfection metabolic changes need to be depicted. Objective. We aimed to evaluate the body composition changes in patients with either HIV and HCV monoinfections or HIV/HCV coinfection. Methods. 123 young men divided into three groups: 41 with HIV/HCV coinfection, 42 with HIV-monoinfection, and 40 with HCV-monoinfection were evaluated for total and regional bone and soft tissue body composition assessments using a Dual-energy X-ray absorptiometry (DXA) and were compared with 40 healthy men with age and body mass index similar to the study groups. To detect sarcopenia, we calculated the appendicular limbs’ lean mass index (ALMI), for obesity, we used the percent of body fat, and for lipodystrophy, we calculated the trunk/limbs index. Results. HIV/HCV coinfection is associated with a significant higher bone demineralization in all regions of interest compared to HCV or HIV monoinfections and to controls. The prevalence of bone demineralization in HIV/ HCV patients was 31.7%, more frequently at lumbar spine. Fat mass and lean mass were significantly lower in HIV/ HCV-coinfected patients than in controls. Lipodystrophy was found in similar percentages in all three evaluated groups (80.4% in HIV/HCV, 92.5% in HIV, and 95% in the HCV group). Sarcopenia was higher in HIV/HCV group (43.9%) and important in HCV-monoinfection group (30%). Conclusions. HIV/HCV-coinfected patients had the highest prevalence of bone demineralization, fat mass, and lean mass loss, compared to controls and to HIV and HCV monoinfections. -

Evolution of Pulmonary Hypertension in Hyperthyroid PatientsActa Endo (Buc) 2012 8(3): 443-452 doi: 10.4183/aeb.2012.443
AbstractIntroduction. Pulmonary hypertension (PHT) is a quite frequent echocardiographic finding in hyperthyroid patients and it regresses slowly under therapy with thiamazol.\r\nAim. The aim of the study was to follow the evolution of PHT over a period of a year, in two groups of hyperthyroid patients.\r\nMaterial and Methods. We followed up two groups of patients: one consisted of patients with chronic Graves Basedow\r\ndisease, some of them with good response to antithyroidian treatment and some other patients with repeated episodes of\r\ndecompensation despite medical therapy. The second group contained new diagnosed cases, a supgroup of patients with overt hyperthyroidism and one with subclinical forms. All 4 subgroups were followed over a period of 12 months. These subjects underwent thyroid hormone determinations and echocardiographic examination at 0, 1, 3, 6 and 12 months.\r\nResults. Our study group consisted of 92 patients with hyperthyroidism of different etiologies. None of the subjects had pulmonary or cardiovascular diseases severe\r\nenough to cause PHT by itself. We determined the presence and severity of pulmonary hypertension at the initial visit and followed its evolution at each scheduled visit in all four subgroups. All patients got antithyroidian therapy with thiamazol, but some chronic cases, with episodes of exacerbation, needed adjustments of their initial treatment. We noticed that PHT appeared in a higher percent and was more severe in the patients with severe hyperthyroidism or in the chronic cases with poor therapeutic response. We observed after some months a tendency to regression in\r\nthe well controlled patients or in those with subclinical disease.\r\nConclusion. The duration and severity of hyperthyroidism had a strong influence on the evolution of pulmonary hypertension in our patients. -

The effect of cabergoline on secretion of SICAM 1 and cytokines in human pituitary adenoma cell cultureActa Endo (Buc) 2010 6(4): 443-454 doi: 10.4183/aeb.2010.443
AbstractOur aim was to explore the interactions of intercellular adhesion molecule (sICAM-1), TNF-α (tumor necrosis factor-α), interleukin-1α (IL-1α) and interleukin-6 (IL-6) with\r\ndopamine agonists in a culture of adenomatous cells from an nonfunctional macroadenoma.\r\nMaterials and methods. Tissue specimen from pituitary macroadenoma removed in transsphenoidal surgery was prepared for primary culture. Cells were counted and plated at 105/well into 24-well plates in a final volume of 1ml. Cabergoline in molar doses of 10-6, 10-7, 10-8, 10-9 was added and the cells were incubated for 4 days. sICAM-1, TNF-α, IL-1α, IL-6 were measured from cell-culture supernatants by ELISA kits.\r\nResults. sICAM-1, TNF-α, IL-1α and IL-6 were detected in the untreated control cultures after a 4d period. There was a negative correlation between TNFα and IL-1α (p=0.007).\r\nThe levels of PRL and hGH had measurable values above those found in culture medium without tumor cells. PRL positively correlated with IL-1α ( p=0.05). hGH positively correlated with cell proliferation (p=0.049). Cabergoline treatment showed that IL-6 progressively decreased with the dose, ranging from -27.41% to -76.44%. TNF-α significantly decreased (-65.90%; p<0.03)at the cabergoline 10-7 M dose. IL-1α progressively increased with cabergoline dose, ranging\r\nfrom -2.53% to 345 %. sICAM-1 was significantly reduced by cabergoline at 10-9 (-47.12 %; p=0.045) and 10-6 M (-59.16%; p=0.01) doses. TNF-α positively correlated with PRL (p=0.025); IL-6 positively correlated with hGH (p=0.044); sICAM-1 negatively correlated with hGH\r\n(p=0.009), TNFα (p=0.025) and IL-1α (p=0.044).\r\nConclusions. These data support the existence of an immunoendocrine network in pituitary tumorigenesis; TNF-α, IL-6, IL-1α, sICAM-1 significantly interfered by cabergoline\r\ntreatment in a dose-dependent way. However, future studies on different types of pituitary tumours are needed to confirm these findings. -

Evaluation Of First Year Response To Treatment In Cases With Growth Hormone DeficiencyActa Endo (Buc) 2016 12(4): 443-449 doi: 10.4183/aeb.2016.443
AbstractBackground/Aims. Growth hormone (GH) treatment has severe cost burden on patients, their families, and healthcare systems. Therefore, accuracy of diagnosis should be confirmed; factors affecting the response to treatment should be defined. The present study is performed to evaluate auxiliary diagnostic parameters and factors affecting treatment in growth hormone deficiency (GHD). Methods. In this study, 142 patients under the age of 16, with at least one year of treatment, were included. Treatment dose of somatropin was 0.2 mg/kg/week in all cases. Response to treatment was evaluated by measuring annual height and height standard deviation score (SDS) gains every 3 months. Results. Male to female ratio was 79 to 63, and follow-up duration before the treatment was 0.89±0.38 years. Annual growth rate before the treatment was 2.92±1.02 cm, and age at the treatment initiation was 9.97±3.22 years. Height gain SDS at the end of the first year was significantly higher in cases which were at the prepuberty, had severe short stature, low height SDS-mid parental height SDS (HSDS-MPHSDS), and initiated treatment at earlier ages. Correlations in height gain and height SDS gain at the end of the first year were significant between bone age at treatment baseline, delta SDS factors, L-dopa and clonidine stimulation results (both are p<0.01). Conclusion. Height gain was positively related to body mass index, whereas negatively to bone age at treatment baseline, responses obtained from stimulation tests, and delta SDS values. In the treatment evaluation, the parameters which can affect according to model chosen by the investigator, may differ. -

The C677T Methylenetetrahydrofolate Reductase Mutation and Alzheimer’s Disease: A meta-analysis of 33 StudiesActa Endo (Buc) 2014 10(3): 443-456 doi: 10.4183/aeb.2014.443
AbstractContext. Data are conflicting concerning risk for Alzheimer’s disease (AD) and 5,10-methylenetetrahydrofolate reductase genetic variant (MTHFR C677T). Objective. The aim of the study was to investigate the associations of MTHFR C677T and risk of developing AD. Design and Methods. We searched the relevant articles by using Medline, web of science, and abstracts of conference proceedings. The meta-analysis and statistical analyses were performed using Stata. Results. In 33 included studies which provided 4518 cases and 5476 controls, the analysis for investigating the association between C677T allele T and the risk of developing AD relative to the allele C revealed no heterogeneity (p=0.088, I2=26.1%) between the 33 studies; the random effects (RE) pooled OR was significant: [RE OR=1.13(1.05-1.22)]. In subgroup analysis, we only observed the significant results in Asian populations. The pooled analysis for MTHFR 677 CT+TT vs. 677CC revealed a significant result [fixed effect (FE) OR=1.22(1.10-1.34)]. However, we did not observe significant associations in Europeans when comparing MTHFR 677 CT+TT with 677CC in subgroup analysis. The pooled analysis for MTHFR 677 TT vs. 677CC+CT did not reveal significant results: [FE OR=1.08(0.95-1.22)]. Conclusion. The risk allele T of MTHFR C677T is associated with high risk of AD in Asian populations, but not in Europeans. -

Factors that Affect the Glycemic Control Achieved by Switching to Insulin Degludec/ Aspart in Insulin-Treated Patients with Type 1 and Type 2 Diabetes in a Real-World Setting: a Non-Interventional, Retrospective Cohort StudyActa Endo (Buc) 2020 16(4): 443-448 doi: 10.4183/aeb.2020.443
AbstractBackground. Insulin degludec/aspart (IDegAsp) is a co-formulation with IDeg and IAsp. Different insulin regimens may be switched to IDegAsp. In this study, we aimed to find out the effect of switch to IDegAsp on glycemic control and whether the basal characteristics and treatment modalities of the patients affect the change in glycemic control brought by switch to IDegAsp. Methods. We retrospectively analyzed the records of 78 patients whose insulin therapies (basal+bolus, premixed analogues or basal only) were switched on a 1:1 unit basis to IDegAsp±bolus insulin. Oral antidiabetic agents (OADs) given were recorded. At the end of 12th and 24th week, total insulin doses of patients and HbA1c were compared to the baseline. Results. There was a statistically significant decrease at HbA1c at 12 weeks (1.4%; p<0.001). There was not a significant difference in HbA1c between the OAD added group and the group with no new OADs(p=0.1). Basal insulin dose was not statistically different from baseline, whereas bolus insulin dose was significantly lower (p=0.007). At the end of 24 weeks the decrease in HbA1c level from baseline was preserved. Conclusion. Regardless of the baseline insulin regimen, diabetes type and oral antidiabetic drugs given, HbA1c is significantly lowered after switching to IDegAsp. -

A Meta-analysis of Methylenetetrahydrofolate Reductase Gene C677T Polymorphism and Diabetic RetinopathyActa Endo (Buc) 2013 9(3): 445-454 doi: 10.4183/aeb.2013.445
AbstractContext. Results concerning the relationship between the risk of developing diabetic retinopathy (DR) and methylenetetrahydrofolate reductase genetic variant (MTHFR C677T) are inconclusive. Objective. The aim of the present analysis was to investigate the associations of DR with MTHFR C677T. Design and Methods. We searched the relevant articles by using Medline, web of science, and abstracts of conference proceedings. The meta-analysis was performed using Stata. Results. The included 7 studies provided 535 cases of DR and 759 controls. The main analysis for investigating the association between MTHFR 677 TT and the risk of developing DR relative to the 677 CC did not reveal significant heterogeneity (p=0.227, I2=27.6%) between the studies; the fixed effects (FE) pooled OR was significant: FE OR=1.84(1.30-2.61). The analysis for the association between MTHFR 677 TT and the risk of developing DR relative to the 677 CC+CT revealed heterogeneity (p=0.082, I2=48.9%) between the studies; the random effects (RE) pooled OR was significant: RE OR=1.72(1.07-2.76). In addition, T carriers have 31% higher risk of developing DR compared with homozygotes for C [OR=1.31(1.03-1.66)]. Conclusions. The present metaanalysis suggested an association between MTHFR C677T and DR and provided evidence that the TT genotype of the MTHFR C677T contributes to susceptibility to DR. -

The G894T polymorphism of endothelial nitric oxide synthase gene and the endocrine-metabolic changes in metabolic syndrome: a romanian case-control studyActa Endo (Buc) 2009 5(4): 447-458 doi: 10.4183/aeb.2009.447
AbstractBackground. Genetic variants of the endothelial nitric oxide synthase (eNOS) gene have\r\nbeen reported to be associated with cardiovascular disease. We hypothesized that G894T\r\npolymorphism might trigger many of the endocrine-metabolic changes related to metabolic\r\nsyndrome (MetS).\r\nStudy Design. 148 subjects with MetS and 142 healthy control subjects aged 23-60 years\r\nwere studied. Fasting serum levels of insulin, cortisol, 17-OH Progesterone, DHEA,\r\nandrostendione, IGF1, GH, PRL, CRP, resistin and biochemical profile were evaluated. G894T\r\n(eNOS) polymorphism was assayed by using PCR-RFLP technique.\r\nResults. The frequencies of genotypes and alleles of G894T polymorphism did not deviate\r\nfrom the Hardy-Weinberg equilibrium. In the MetS group the percentages of both GT (51.35 vs.\r\n39.44; OR=2.09; CI=1.27-3.45; p= 0.003) and TT (16.22 vs. 8.45; OR=3.08; CI=1.41-6.74;\r\np=0.003) genotypes and T allele (41.9 vs. 28.2; OR=1.83; CI=1.3- 2.6; p=0.0005) significantly\r\nincreased compared to control group. The G894T polymorphism was more significantly\r\nassociated with the MetS in the presence of cortisol, 17-OH Progesterone, PRL, IGF1 and CRP\r\n(OR= 8.20; 95%CI=2.31-29.08; p=0.001) and significantly stronger in the presence of IGF1,\r\nPRL, 17OHP, resistin and CRP (OR= 10.21; 95%CI=2.42-43.05; p=0.002). The T allele carriers\r\nhad higher values of waist circumference, systolic and diastolic blood pressure, cortisol, 17-OHP,\r\nandrostendione, PRL, resistin and lower values of glucose, HOMA-IR in MetS group; The TT\r\ngenotype carriers had higher values of triglyceride in both control and MetS group.\r\nConclusion. Our results show an interaction between the G894T polymorphism and its\r\nphenotypes in conferring a higher susceptibility to the endocrine changes involved in\r\npathogenesis of MetS suggesting a role of the eNOS gene in the modulation of the molecular\r\nendocrine mechanisms. -

Diagnostic and therapeutic approach to small bowel carcinoid tumor. Case reportActa Endo (Buc) 2008 4(4): 447-453 doi: 10.4183/aeb.2008.447
AbstractDetecting the primary tumours in carcinoid malignancies is a critical challenge. We report the case of a 25 year old male patient with a typical clinical carcinoid syndrome. Metastatic carcinoid malignancy was easily diagnosed by very high plasma chromogranin, plasma serotonin and urinary 5-Hydroxy-Indol Acetic Acid levels, and the detection of multiple liver metastases by ultrasound. Somatostatin receptor scintigraphy (SRS) failed to detect the primary lesion, as did upper and lower gastrointestinal (GI) tract endoscopy, bronchoscopy, total body CT, MRI, and GI video tract endoscopy; only F-DOPA PET-scan ascertained and accurately localized the primary ileal tumor. Surgery confirmed the localisation, and pathology revealed a 3 cm highly differentiated carcinoid tumor with low proliferation grade (Ki67<2). The therapy with short and long acting somatostatin analogues was started before surgery and continued after surgical intervention. There was a regression of the clinical carcinoid syndrome and a numerical involution of liver metastases, but the levels of chromogranin A and serotonin remained elevated. Other therapeutical option should be discussed. -

The Effect of Exenatide Therapy in Previously Insulin-Treated Type 2 Diabetic PatientsActa Endo (Buc) 2017 13(4): 447-453 doi: 10.4183/aeb.2017.447
AbstractObjective. To evaluate the effect of multiple daily injection (MDI) treatment replaced by Exenatide BID as compared with continuation of MDI. Patients and Methods. A total of 140 patients with type 2 diabetes, taking metformin and multiple daily insulin injections, were randomized to exenatide or insulin group that continued their insulin treatment. Patients were followed-up for 16 weeks. Blood glucose profiles, BMI, waist circumference, HbA1C, serum lipids and side effects were assesssed at weeks 0,12 and 16. Results. There were no significant differences between the two groups with respect to baseline parameters. Glycemic control was similar between the two groups. The mean changes in HbA1C in exenatide group were -0.66±0.63% and in insulin group -0.74±0.92 % (p=0.594). In exenatide group, 59.6 % of patients and in insulin group 85.71 % of patients had maintained or improved glycemic control at the end of the study. In insulin group, insulin requirement increased 5.86 ± 4.46 units/day. Body weight and waist circumference decreased significantly in exenatide treatment group with respect to insulin group (p<0.001). Conclusions. Substituting exenatide for insulin might be an option in insulin-treated, type 2 diabetic patients having obesity, and poor glycemic control. However, patients with longer duration of diabetes and insulin treatment and with lower C-peptide levels might not benefit from exenatide therapy.
