Genetic predictors of skeletal outcomes in healthy fertile women: the Bonturno study.

Skeletal traits as height (Ht) or bone mineral density (BMD) are strongly inherited. Low-density lipoprotein receptor-related protein 5 (LRP5) and farnesyl diphosphonate synthase (FDPS) are candidate genes for bone phenotypes. From Bonturno study, we genotyped 570 healthy Caucasian women aged 20 to 50 years (yrs) for LRP5 rs4988321 (A/G) and rs3736228 (C/T) and FDPS rs2297480 (A/C) single nucleotide polymorphisms. Serum C-telopeptide of type I collagen (CTX), osteocalcin (OC), and N-terminal propeptide of type I procollagen (P1NP) were measured in BMD-evaluated subjects at lumbar spine (LS), total hip (TH) and femoral neck (FN) sites. LRP5 rs4988321 locus correlated with FN-BMD (P = 0.0230), while LRP5 rs3736228 genotypes differed in LS-BMD (P = 0.0428). When clustered by age, lower FN-BMD was detected in LRP5 GG (P = 0.030) subjects of 41 to 50 years but not in younger. Both LRP5 GG and CC genotypes showed higher age-adjusted values of OC, CTX and P1NP. Increased CTX values were in LRP5 GGCC subjects than in those having at least one LRP5 A plus T alleles (P = 0.0190). LRP5 CC, GG or GGCC subjects with at least one FDPS C allele showed higher levels of CTX and OC in 31 to 40 yrs or older subjects. In conclusion, LRP5 and FDPS loci age-specifically affect skeletal traits in healthy fertile women.

Headache, anxiety and depressive disorders: the HADAS study.

The objective of this paper was to assess prevalence and characteristics of anxiety and depression in migraine without aura and tension-type headache, either isolated or in combination. Although the association between headache and psychiatric disorders is undisputed, patients with migraine and/or tension-type headache have been frequently investigated in different settings and using different tests, which prevents meaningful comparisons. Psychiatric comorbidity was tested through structured interview and the MINI inventory in 158 adults with migraine without aura and in 216 persons with tension-type headache or migraine plus tension-type headache. 49 patients reported psychiatric disorders: migraine 10.9%, tension-type headache 12.8%, and migraine plus tension-type headache 21.4%. The MINI detected a depressive episode in 59.9, 67.0, and 69.6% of cases. Values were 18.4, 19.3, and 18.4% for anxiety, 12.7, 5.5, and 14.2%, for panic disorder and 2.3, 1.1 and 9.4% (p = 0.009) for obsessive-compulsive disorder. Multivariate analysis showed panic disorder prevailing in migraine compared with the other groups (OR 2.9; 95% CI 1.2-7.0). The association was higher (OR 6.3; 95% CI 1.4-28.5) when migraine (with or without tension-type headache) was compared to pure tension-type headache. This also applied to obsessive-compulsive disorder (OR 4.8; 95% CI 1.1-20.9) in migraine plus tension-type headache. Psychopathology of primary headache can reflect shared risk factors, pathophysiologic mechanisms, and disease burden.

Age-specific effects of estrogen receptors' polymorphisms on the bone traits in healthy fertile women: the BONTURNO study.

BACKGROUND: Skeletal characteristics such as height (Ht), bone mineral density (BMD) or bone turnover markers are strongly inherited. Common variants in the genes encoding for estrogen receptor alpha (ESR1) and beta (ESR2) are proposed as candidates for influencing bone phenotypes at the population level. METHODS: We studied 641 healthy premenopausal women aged 20-50 years (yrs) participating into the BONTURNO study. Exclusion criteria were irregular cyclic menses, low trauma fracture, metabolic bone or chronic diseases. Serum C-telopeptide of type I collagen (CTX), osteocalcin (OC), and N-terminal propeptide of type I procollagen (P1NP) were measured in all enrolled subjects, who underwent to lumbar spine (LS), total hip (TH) and femoral neck (FN) BMD evaluation by DXA. Five hundred seventy Caucasian women were genotyped for ESR1 rs2234693 and rs9340799 and ESR2 rs4986938 polymorphisms. RESULTS: Although no genotype differences were found in body parameters, subjects with combined ESR1 CCGG plus ESR2 AA-AG genotype were taller than those with opposite genotype (P = 0.044). Moreover, ESR1 rs2234693 genotypes correlated with family history of osteoporosis (FHO) and hip fracture (FHF) (P < 0.01), while ESR2 AA-AC genotypes were strongly associated with FHF (OR 2.387, 95% CI 1.432-3.977; P < 0.001).When clustered by age, 20-30 yrs old subjects, having at least one ESR1 rs2234693 C allele presented lower LS- (P = 0.008) and TH-BMD (P = 0.047) than TT genotypes. In 41-50 yrs age, lower FN-BMD was associated with ESR2 AA (P = 0.0180) subjects than in those with the opposite genotype. ESR1 rs2234693 and rs9340799 and ESR2 rs4986938 polymorphisms did not correlate with age-adjusted values of OC, CTX and P1NP. CONCLUSION: These findings support the presence of age-specific effects of ESR1 and ESR2 polymorphisms on various skeletal traits in healthy fertile women.
