Haemochromatosis gene (HFE) polymorphisms and migraine: an association study.

Several studies have suggested that iron metabolism may be involved in the pathogenesis of migraine. Using a case-control design, we performed an association study in a cohort of Italian migraine patients to evaluate whether a particular allele or genotype of the haemochromatosis gene (HFE) would modify the occurrence and clinical features of the disease. We genotyped 256 migraine patients and 237 healthy age-, sex- and ethnicity-matched controls for the C282Y and H63D polymorphisms of the HFE gene. Phenotype and allele frequencies of both polymorphisms were similarly distributed in migraine patients and controls. The patients carrying the DD genotype of the H63D polymorphism showed a later age at onset of the disease and an increased number of migraine attacks. Our data suggest that the HFE gene is not a major disease gene for migraine. However, the H63D polymorphism of the HFE gene may be considered a modifying genetic factor in migraine.

Insulin sensitivity is impaired in patients with migraine.

Several studies have shown the presence of a comorbidity between migraine and vascular diseases, like hypertension and stroke. The mechanisms of this comorbidity are unknown. Impaired insulin sensitivity has recently emerged as a risk factor for hypertension and stroke. We evaluated insulin sensitivity in 30 young, nonobese, nondiabetic, normotensive migraine patients and in 15 healthy controls. During the OGTT, glucose plasma concentrations were significantly higher in migraineurs than in controls. Insulin sensitivity, as measured by ISI-stumvoll and OGIS-180 indexes, was significantly altered in migraine. Our data show that insulin sensitivity is impaired in migraine and suggest a role for insulin resistance in the comorbidity between migraine and vascular diseases.

Lack of association between the 3092 T-->C Clock gene polymorphism and cluster headache.

Recent studies suggested that genetic factors play a role in cluster headache (CH). However, the type and the number of genes involved in the disease are still unclear. We performed an association study in a cohort of Italian CH patients to evaluate whether a particular allele or genotype of the Clock gene would modify the occurrence and the clinical features of the disease. One hundred and seven CH patients, diagnosed according to the International Classification of Headache Disorders, 2nd Edition, (ICHD-II) criteria, and 210 healthy age, sex and ethnicity-matched controls were genotyped for the 3092 T-->C Clock gene polymorphism (also known as 3111 T-->C). Phenotype and allele frequencies were similarly distributed in CH patients and controls. The clinical features of the disease were not significantly influenced by different genotypes. In conclusion, our study suggests that the 3092 T-->C polymorphism of the Clock gene is unlikely to play an important role in cluster headache.

A polymorphism of the hypocretin receptor 2 gene is associated with cluster headache.

Several polymorphisms of the hypocretin/orexin system genes were evaluated in 109 cluster headache patients and 211 controls. The 1246 G>A polymorphism of the gene was significantly different between cases and controls. Homozygosity for the G allele was associated with an increased disease risk (OR: 6.79, 95% CI, 2.25 to 22.99). The data suggest that the HCRTR2 gene or a linked locus significantly modulates the risk for cluster headache.

Lack of interaction between a polymorphism in the dopamine D2 receptor gene and the clinical features of migraine.

The purpose of this study was to evaluate whether a particular genotype of the dopamine D2 receptor (DRD2) gene would affect the clinical features of migraine. In a group of 118 migraineurs (55 migraine with aura and 63 migraine without aura patients), we tested the association of the biallelic C/T NcoI DRD2 polymorphism with several characteristics of the disease. Genotype and allele frequencies resulted similarly distributed in migraine with aura and migraine without aura patients (chi2 = 1.58, P = 0.45 and chi2 = 0.09, P = 0.77, respectively). The different DRD2 genotypes (C/C, C/T and T/T) had no significant effects on age at onset of migraine, presence of premonitory phenomena, frequency of headache attacks, associated symptoms, psychological features and quality of life of our migraine patients. The results of our study do not support a role for the DRD2 gene in modifying the clinical features of migraine.

Presence of human papillomavirus and Epstein-Barr virus in the cervix of women infected with the human immunodeficiency virus.

The presence of human papillomavirus (HPV) and Epstein-Barr virus (EBV) was sought in cervical scrapings from 110 human immunodeficiency virus (HIV)-infected women to evaluate the role of these viruses as risk factors for squamous intraepithelial lesions of the cervix. By using PCR, presence of HPV-DNA and EBV-DNA was found in 60.9% (67/110) and in 10% (11/110) of clinical samples, respectively. Identification of oncogenic group of HPV by hybrid capture (HC II, Murex-Digene) indicated the presence of low-risk HPV in 13 (19.4%) patients, high-risk HPV in 28 (41.8%), and both types of HPV in 26 (38.8%) patients. Squamous intraepithelial lesions were present in 59 cases, being low-grade (n = 52) and high-grade (n = 7) lesions. HPV was detected in 84.7% of patients with lesions, in association with low-grade (43/52) and high-grade lesions (7/7), and in 33% of patients without lesions. EBV-DNA was detected in 8 patients with low-grade lesions and in 3 patients without lesions. Concurrent genital HPV and EBV infection was observed in 9 cases. HPV was associated with detection of squamous intraepithelial lesions [OR = 3.55; 95% CI = (1.96; 6.48)]. No significant association was found between presence of EBV and detection of lesions, both in case of EBV infection alone [OR = 1.4; 95% CI = (0. 93; 2.12)] and in case of HPV/EBV combined infection [OR = 0.87; 95%CI = (0.54; 1.42)]. These data confirm the significant role of HPV as risk factor for squamous intraepithelial lesions and suggest that EBV could not be involved in the pathogenesis of the lesions that arise in the cervix of HIV-positive women.

Lipid profile during pregnancy in HIV-infected women.

PURPOSE: We investigated the evolution of serum lipid levels in HIV-infected pregnant women and the potential effect of antiretroviral treatment during pregnancy using data from a national surveillance study. METHOD: Fasting lipid measurements collected during routine care in pregnancy were used, analyzing longitudinal changes and differences in lipid values at each trimester by protease inhibitors (PIs) and stavudine use. Multivariate analyses were used to control for simultaneous factors potentially leading to hyperlipidemia. Study population included 248 women. RESULTS: Lipid values increased progressively and significantly during pregnancy: mean increases between the first and third trimesters were 141.6 mg/dL for triglycerides (p < .001), 60.8 mg/dL for total cholesterol (p < .001), 13.7 mg/dL for HDL cholesterol (p < .001), and 17.8 mg/dL for LDL cholesterol (p = .001). At all trimesters, women on PIs had significantly higher triglyceride values compared to women not on PIs. The effect of PIs on cholesterol levels was less consistent. Stavudine showed a dyslipidemic effect at first trimester only. Multivariate analyses confirmed these observations and suggested a potential role of other cofactors in the development of hyperlipidemia during pregnancy. CONCLUSION: The changes observed point to the need to further explore the causes and the clinical correlates of hyperlipidemia during pregnancy in women with HIV.

Prevalence and clinical presentation of subclinical/silent celiac disease in adults: an analysis on a 12-year observation.

BACKGROUND/AIMS: In recent years, an increased incidence of subclinical/silent celiac disease has been reported. Thus, we herein describe the prevalence and the clinical presentation of subclinical/silent celiac disease in 252 consecutive diagnosed celiac patients. METHODOLOGY: From 1988 to 1999 we diagnosed 252 celiac patients (74M and 178F, mean age: 27.9 yrs; range: 15-65 yrs, F/M ratio: 2.4). 144 patients were referred to us due to gastrointestinal symptoms, while 108 were referred to us from other specialists due to unexplained or unresponsive disease. All patients underwent both total immunoglobulin A and antigliadin antibodies antiendomysium antibody and evaluation, followed by gastrointestinal endoscopy with duodenal histological examination. RESULTS: 144 (57.14%) and 108 (42.86%) patients showed classical and subclinical/silent celiac disease, respectively. The most frequent extraintestinal marker of subclinical celiac disease were iron-deficiency anemia (27.77%), alopecia and dermatitis herpetiformis (11.36%), osteoporosis (6.81%) and recurrent aphtous stomatitis (5.68%), while first-degree relatives (30%), Basedow's disease (25%) and insulin-dependent diabetes (20%) were the most frequent in silent celiac disease. CONCLUSIONS: This study confirms the extremely polymorphic nature of this condition that can affect several organs and apparatus without gastrointestinal symptoms. However, a more precise description of subclinical/silent celiac disease can only emerge from screening studies on general populations.
