    Iodine Status after a Decade of Universal Salt Iodization in Romania: A Bicentric Study in Urban Areas

    Acta Endo (Buc) 2014 10(1): 9-20 doi: 10.4183/aeb.2014.9

    Abstract
    Objective. To assess in a bicentric study the current iodine status of schoolchildren, ten years after implementation of the universal salt iodization (USI) in Romania. Subjects and methods. 102 children from 2 towns, aged between 6 and 11 years, were included in the study group: 66 children from Sibiu, a previously endemic area for iodine deficiency disorders and 36 children from Bucharest, a previously borderline iodine intake area. Body mass index (BMI), total body surface area (BSA), median urinary iodine concentration (UIC) and prevalence of goiter were evaluated. Thyroid volume was measured by ultrasonography. The study was approved by the Local Ethics Committee. An informed consent from the parents was obtained. Results. From the 102 schoolchildren in the study group, 59 were girls and 43 were boys. Median UIC in the total number of samples was 175.2 mcg/L, reflecting a sufficient iodine intake, with statistically significant differences between the two urban regions. The median UIC was 187.35 mcg/L in the Sibiu subgroup and 160.2 mcg/L in the Bucharest subgroup (p < 0.001). The total percentage of goiter in the studied subjects was 5.88%. Percentage of goiter, determined by adjusting ultrasound thyroid volume to sex and BSA, was 1.51% in Sibiu and 13.88% in Bucharest, a statistically significant difference (p = 0.011). None of the subjects showed ultrasonographic pattern suggestive of Hashimoto thyroiditis or macronodules. There was no statistically significant difference between the percentages of overweight or obesity in the two subgroups. Conclusions. Ten years after implementation of USI in Romania, a bicentric study suggests that our country is iodine sufficient in urban areas. In order to prevent recurrence of mild iodine deficiency in schoolchildren, a persistent surveillance, use of sustainable measures and public awareness are required. Recurrence of mild iodine deficiency should be avoided, because even mild iodine deficiency impairs cognition in children.

    Both insulin resistance and insulin secretion are involved in the pre-diabetes of acromegaly

    Acta Endo (Buc) 2010 6(1): 35-42 doi: 10.4183/aeb.2010.35

    Abstract
    In acromegalic patients growth hormone (GH) excess induces insulin resistance (IR) but whether this is sufficient for pre-diabetes to occur is a matter of debate.\r\nAim. To assess the relative role of IR and insulin secretion in the pre-diabetes of acromegaly.\r\nMethods. 126 patients with acromegaly (79 women, 47 men) were included. Plasma glucose, GH and insulin levels were measured basal and 30, 60 and 120 minutes during a 75 g oral glucose tolerance test (OGTT). Basal and stimulated IR was assessed by homeostasis model assessment (HOMA), insulin resistance index (HOMA-IR) and insulin sensitivity index (ISI) derived from OGTT (OGTTISI) respectively. Basal and stimulated insulin secretion was assessed using HOMA-B% index and insulinogenic index (IGI), respectively. The local Ethic Committee approved the study.\r\nResults. There were 51 subjects with pre-diabetes and 75 subjects with normal glucose tolerance (NGT). Pre-diabetes group had a significantly higher HOMA-IR index (4.8?3.3 vs 2.5?1.6, p<0.001) and nadir GH in OGTT (9.4 (4.3, 22.2) vs. 4.8 (2.2, 14.5) ng/mL, p=0.02) than NGT group. HOMA-IR did not correlate with nadir GH serum level in pre-diabetes group (r =0.22, p=0.12) but correlated significantly in NGT group (r= 0.5, p<0.001). In contrast, the pre-diabetes group had a lower HOMA-B% index than NGT group (165.4?15.7 vs 228.5?29, p<0.001). HOMA-B% did not correlate with nadir GH in both groups. Unadjusted IGI did not differ between the two groups (0.40?0.07 vs. 0.48?0.05, p=0.34) but became statistically significant after adjusting for both basal IR (HOMA-IR) (0.31?0.06 vs. 0.54?0.05, p=0.01) and stimulated IR (OGTTISI) (0.30?0.06 vs. 0.54?0.05, p=0.005). There were no significant differences between pre-diabetes and NGT groups regarding age, duration of acromegaly and sex.\r\nConclusions. Our data suggest that reduced basal and stimulated insulin secretion express the failure of &#946;-cells adaptation to increased GH-induced-insulin resistance and is the pathogenic mechanism of pre-diabetes in acromegaly.

    Central sleep apnea in acromegaly versus obesity

    Acta Endo (Buc) 2005 1(1): 79-88 doi: 10.4183/aeb.2005.79

    Abstract References
    INTRODUCTION: Sleep apnea syndrome is a common manifestation of acromegaly. Although the obstructive type of apnea was thought to be predominant there are some reports suggesting that central apneic episodes show a high rate and are related to abnormalities of central respiratory control.\r\nAIM: The present study determines the presence and severity of central sleep apnea syndrome in patients with acromegaly compared with obese subjects.\r\nMATERIALS AND METHODS: 35 consecutive acromegalic patients (min GH (growth hormone) during oral glucose tolerance test (OGTT) 6.6 ng/ml) and 19 obese subjects (BMI=44 kg/m2) were polisomnographically recorded between 10 p.m and 6 a.m. Sleep and respiratory disturbances were manually staged according to standard criteria.\r\nRESULTS: The prevalence of sleep apnea syndrome in acromegaly group was 45.7% (16 out of 35 patients). The median of minimum GH level during OGTT was 8.3 ng/ml in apnea group and 5.16 ng/ml in nonapneic group (p>0.05). In acromegaly group with severe sleep apnea syndrome central apnea rate was greater than 10% in 6 out of 7 subjects with REM sleep and in 7 out of 10 with NREM sleep whereas in obesity group this percent was present in 6 out of 18 (REM sleep), respectively 7 out of 19 (NREM sleep).\r\nCONCLUSIONS: The study confirms the high prevalence of sleep apnea in acromegaly. GH serum level is not an indicator for the presence and severity of sleep apnea. Although the total time of central apnea per hour of sleep did not differ between the two groups, the percent (rate) of central apnea was significantly greater in acromegaly group.
