Abstract
Primary open-angle glaucoma (POAG) is a multifactorial disease, etiopathogenesis of which largely depends on growth factors. Possessing a variety of medical and biological effects, these cytokines may influence the development and progression of POAG. AIM to reveal the role of genetic polymorphisms of growth factors in predisposition to developing POAG that is refractory to local hypotensive therapy. MATERIAL AND METHODS The object of the study were 162 patients with stage II-III POAG, in whom local hypotensive therapy was inefficient, 90 patients with stage II-III POAG well controlled on local hypotensive therapy, and 191 controls. The material for the study was venous blood taken from the cubital vein of a proband. Isolation of genomic DNA was performed by phenol-chloroform extraction. Analysis of genetic polymorphisms of growth factors was performed through allelic discrimination. For that, synthesis of DNA was carried out via polymerase chain reaction (PCR). RESULTS It is found that the T IGFR-1 genetic variant (OR=1.34) and a combination of the C VEGF-A and T IGFR-1 genetic variants (OR=1.90) are risk factors of developing POAG that is refractory to local hypotensive therapy. A statistical model for predicting such a risk has been proposed that includes: VEGF-A с.-958C>T genetic marker (rs 833,061), age, concomitant non-inflammatory ocular diseases, microvascular changes in the conjunctiva, the degree of pigmentation of the angle of the anterior chamber, and pseudoexfoliative syndrome. Recognition accuracy of the model is 90.42%. CONCLUSION The T IGFR-1 genetic variant and a combination of the C VEGF-A and T IGFR-1 genetic variants increase the risk of developing POAG that is refractory to local hypotensive therapy.

Abstract
OBJECTIVES To determine whether small head circumference (HC) or birth weight (BW) or both are associated with neonatal and long-term neurologic outcome in very preterm infants. STUDY DESIGN All 2442 live births from the 1997 Epipage study between 26 and 32 weeks of gestational age in 9 regions of France were analyzed. A total of 1395 were tested at age 5 years for cognitive performance and 1315 with school performance reports at age 8 years. Symmetric growth restriction (SGR) was defined by HC and BW <20th percentile and in the same percentile range, and asymmetric growth restriction by at least 1 of HC and BW <20th percentile and the other in a higher decile range. There were 2 forms of asymmetric growth restriction: head growth restriction (HGR) and weight growth restriction (WGR). Appropriate for gestational age was defined by both BW and HC >20th percentile. RESULTS Compared with appropriate for gestational age, SGR was significantly associated with neonatal mortality (aOR 2.99, 95% CI 1.78-5.03), moderate and severe cognitive deficiency (aOR 1.65, 95% CI 1.01-2.71 and aOR 2.61, 95% CI 1.46-4.68, respectively), and poor school performance (aOR 1.79; 95% CI 1.13-2.83). HGR was significantly associated with severe cognitive deficiency (aOR 2.07, 95% CI 1.15-3.74). WGR was not significantly associated with cognitive or school performance despite higher rates of neonatal morbidity. CONCLUSIONS SGR in preterm infants was associated with neonatal mortality and impaired cognitive and school performance. The outcome of asymmetric growth restriction differed according to HC. HGR was associated with impaired cognitive function; WGR was not.

Regulation of IGFBP3 gene expression in short children born small for gestational age. Growth Horm IGF Res 2011; 21:349-355. [PMID: 22001433 DOI: 10.1016/j.ghir.2011.09.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2011] [Revised: 07/13/2011] [Accepted: 09/17/2011] [Indexed: 10/16/2022]
Abstract
OBJECTIVE Approximately 6% of newborns at term are small for gestational age (SGA) and present a birth weight and/or length less than -2SD from the mean. SGA infants are at increased risk for perinatal morbidity, associated psychological and/or mental problems, persistent short stature (about 15% of subjects) and metabolic alterations. Insulin-like growth factors (IGFs), their common receptor (IGF1R) and their binding proteins (IGFBPs) play a critical role in fetal and postnatal growth. In these genes common polymorphisms, such as single nucleotide polymorphisms and variable number of tandem repeats, have been investigated with conflicting results with respect to SGA-related outcomes, and the functional role of these gene variants remains to be elucidated. DESIGN The study group consisted of 100 pre-pubertal short children born SGA and 94 healthy controls, matched for sex and age, recruited at the Department of Biomedicine of Development Age of the Bari University and at the Paediatric Department of the Messina Hospital. In the present study we analyzed the allelic frequency of the polymorphisms -795 G/A, -667 G/A, -396 C/T in the IGFBP3 in SGA children and their influence on the basal and insulin-stimulated transcriptional activity of the gene. RESULTS We found that the polymorphisms -667 G/A and -396 C/T in the IGFBP3 promoter region are capable of having an effect on the transcriptional activity of the gene, although with opposing effects. Interestingly, the -667 G/A polymorphism has a negative impact on the IGFBP3 transcription, while the -396 C/T polymorphism determines an increase of the transcriptional activity of the IGFBP3 gene promoter. Interestingly, we found that the -396 C/T polymorphism correlates with lower birth length in SGA children. Most importantly, while the diminished IGFBP3 transcriptional activity induced by the -667A polymorphism was significantly recovered after insulin administration (p-value<0.05), the increased transcriptional activity caused by the -396T polymorphism was not restored to baseline levels by insulin. CONCLUSIONS Altogether our results demonstrated that the -667 G/A and the -396 C/T polymorphisms in IGFBP3 promoter region influence the basal transcriptional activity of the gene.

Abstract
The phenotype caused by human genetic insulin-like growth factor-I (IGF-I) defects is characterised by the association of intrauterine and postnatal growth retardation with sensorineural deafness and intellectual deficit. This syndrome is extremely rare and only four cases have been reported. Addition clinical features may include microcephaly and later in life adiposity and insulin resistance. Partial gonadal dysfunction and osteoporosis may also be present. A case of partial IGF-I deficiency has recently been described and was associated with pre- and postnatal growth retardation and microcephaly but the developmental delay was mild and hearing tests were normal. IGF-I deficiency is transmitted as an autosomal recessive trait and is caused by homozygous mutations in the IGF1 gene. Currently these patients can benefit from recombinant IGF-I which is now available for treatment. These observations demonstrate that the integrity of IGF-I signalling is important for normal growth and brain development.

Abstract
Infants with a very low birth weight are at risk of a reduced number of nephrons predisposing to kidney disorder, hypertension, and metabolic syndrome. Approximately 3% of infants are born small for gestational age (SGA), defined as birth weight and/or length at least 2 SD below the mean for gestational age (GA), independently of whether these children are born prematurely or at term. About 10% of these children do not show postnatal catch-up growth and remain of short stature during childhood. Most of these infants are not growth hormone (GH)-deficient, but may have GH resistance. Although GH-resistant, the majority of patients benefit from GH therapy, normalize height during childhood, maintain a normal growth velocity during puberty, and attain a normal adult height. To date, GH has been shown to be safe and no significant adverse effects have been demonstrated. Children with congenital chronic kidney disease (CKD) are born with subnormal birth weight and length and about 25% are born SGA. Shortness and need for GH treatment is highly correlated with weight at birth and gestational age. Primary renal disorders modify the response to GH treatment. Analysis of whether SGA is an additional risk factor for CKD regarding the development of hypertension, metabolic syndrome and cardiovascular complications is required.

Abstract
Previous genome-wide association studies (GWASs) have identified several loci associated with human height; however, such evidence was mostly reported in Caucasian populations. Since the different distributions of height between populations suggest their different genetic backgrounds, analysis in different populations would be useful. Here, we present the results of a GWAS for adult height in 19 633 Japanese subjects. We found eight significantly associated loci that satisfied the genome-wide significance level (P < 5.0 x 10(-8)). Of these, the association to the LHX3-QSOX2 locus was entirely novel (rs12338076, P = 2.2 x 10(-8)). We also identified the association to the IGF1 locus (rs17032362, P = 8.1 x 10(-9)). Conditional association analysis in the IGF1 locus with rs17032362 suggested the existence of an additional independent association with height to this locus (rs1457595, P = 1.2 x 10(-5)). We observed large differences in the allele frequencies of rs17032362 and rs1457595 between Japanese (34 and 9%, respectively) and Caucasian (1.7 and 0%, respectively) populations, thereby suggesting weak statistical powers for the IGF1 locus in the previous Caucasian GWASs for height. We extensively compared our results with those of previous reports on the Caucasian and Korean populations. We were able to replicate all four loci previously reported in Koreans (EFEMP1, ZBTB38, HMGA1 and PLAG1, P < 5.0 x 10(-8)) and 15 loci identified in Caucasians (P < 0.001). The combination of the height-associated loci identified in our study and the previous GWASs demonstrated an effect size of 1.26 cm (95% confidence interval: 1.18-1.34) per 1.0 increase of the normalized Z score for height-increasing alleles, explaining 4.6% of the total variance of adult height.
