Carotid intima media-thickness is increased in obese children metabolically healthy, metabolically unhealthy, and with metabolic syndrome, compared to the non-obese controls.

The prevalence of obesity continues to increase. Obesity is associated with cardiovascular risk factors: elevated blood pressure, dyslipidemia and glycemic alterations, causing metabolic syndrome. A subgroup of obese, Metabolically Healthy Obese (MHO), appears to be less prone to the development of metabolic disturbances. Carotid intima-media thickness (cIMT) is a non-invasive marker of subclinical atherosclerosis and it is associated with increased risk of CVD events. To investigate the cardiovascular risk, demonstrated through the increase of cIMT in obese subjects without Metabolic Syndrome (MetS), we have studied cIMT in MHO, metabolically unhealthy obese (MUO) and obese with MetS diagnosed with the IDEFICS criteria and compared to a control group. 224 obese children aged 6 to 21 years (13,50 ± 4.01 years) and 103 normal weight subjects aged 7 to 19 years (13.2 ± 4.1 years) were studied. The body mass index (BMI) of the obese children was ≥ the 95th percentile. Based on the IDEFICS criteria, we divided the obese subjects in three groups: MHO if no criteria were out of range, MUO if, at least, one of the criteria was out of range and MetS group if all the IDEFICS criteria were present. In all the subjects cIMT was measured with color Doppler by a vascular surgeon. Differences in the means of the variables were tested by ANOVA. Based on the IDEFICS criteria, 32 subjects were affected by MetS (14..3%), 66 were considered MUO (29.4%) and 126 MHO (56.3%). Comparison of mean cIMT highlighted a significant difference (p < 0.05) between the groups of obese children (MHO, MUO and MetS) and controls for both carotid arteries. We did not find significative difference in the value of cIMT in MHO, MUO and MetS subjects, and all groups showed cIMT value higher compared to cIMT of the controls.

Evaluación de la biopsia de fusión elástica vs. biopsia sistemática para la detección del cáncer de próstata: resultados de un estudio multicéntrico en 1.119 pacientes / Elastic fusion biopsy versus systematic biopsy for prostate cancer detection: Results of a multicentric study on 1.119 patients

Objetivos: Evaluar la precisión de las biopsias guiada y sistemática para la detección del cáncer de próstata (CP) y CP clínicamente significativo (CPCS) en la práctica diaria, analizando el requerimiento de biopsias sistemáticas adicionales en el momento de la biopsia guiada. Pacientes y métodos: De nuestra base de datos multicéntrica que incluye 2.115 pacientes sometidos a biopsia de fusión con el sistema Koelis(TM) entre 2010 y 2017, seleccionamos 1.119 pacientes que recibieron biopsias guiadas (una mediana de 3 por cada lesión), con posterior muestreo sistemático (12 a 14 núcleos). Se evaluó la tasa de detección de cáncer (TDC) global y clínicamente significativa de las biopsias de fusión de Koelis(TM), comparando la biopsia guiada con la sistemática. Como objetivo secundario, está la identificación de los predictores de detección de CP. Resultados: La TDC de la biopsia guiada fue del 48% para todos los tipos de cáncer y del 33% para el CPCS. El muestreo de próstata sistemático adicional mejoró la TDC global en un 15% y en un 12% para CPCS. Se detectó CP en el 35, 69 y 92% de los pacientes con lesiones calificadas como PI-RADS 3, 4 y 5, respectivamente. Una puntuación elevada de PI-RADS y un examen rectal digital positivo fueron factores predictores de CP, y la condición «biopsia naïve» se asoció con CPCS. Conclusión: En la práctica diaria, la biopsia guiada con Koelis(TM) logra una buena TDC para todos los CP y CPCS, y mejora significativamente con el muestreo sistemático posterior de la próstata. Los excelentes resultados de la biopsia por fusión se confirman también en pacientes naïve. La puntuación PI-RADS elevada y el examen rectal digital positivo están altamente asociados con la presencia de CP

Objectives: To assess the accuracy of targeted and systematic biopsies for the detection of prostate cancer (PCa) and clinically significant PCa (csPCa) in the everyday practice, evaluating the need for additional systematic biopsies at the time of targeted biopsy. Patients and methods: From our multicentric database gathering data on 2,115 patients who underwent fusion biopsy with Koelis(TM) system between 2010 and 2017, we selected 1,119 patients who received targeted biopsies (a median of 3 for each target), followed by systematic sampling of the prostate (12 to 14 cores). Overall and clinically significant cancer detection rate (CDR) of Koelis(TM) fusion biopsies were assessed, comparing target and systematic biopsies. Secondary endpoint was the identification of predictors of PCa detection. Results: The CDR of targeted biopsies only was 48% for all cancers and 33% for csPCa. The performance of additional, systematic prostate sampling improved the CDR of 15% for all cancers and of 12% for csPCa. PCa was detected in 35%, 69%, and 92% of patients with lesions scored as PI-RADS 3, 4 and 5, respectively. Elevated PI-RADS score and positive digital rectal examination were predictors of PCa, whereas biopsy-naïve status was associated with csPCa. Conclusion: In the everyday practice target biopsy with Koelis(TM) achieves a good CDR for all PCa and csPCa, which is significantly improved by subsequent systematic sampling of the prostate. The outstanding outcomes of fusion biopsy are confirmed also in biopsy-naïve patients. Elevated PI-RADS score and positive digital rectal examination are strongly associated with presence of PCa

A multicentric study on accurate grading of prostate cancer with systematic and MRI/US fusion targeted biopsies: comparison with final histopathology after radical prostatectomy.

OBJECTIVE: To evaluate the accuracy in histologic grading of MRI/US image fusion biopsy by comparing histopathology between systematic biopsies (SB), targeted biopsies (TB) and the combination of both (SB + TB) with the final histopathologic outcomes of radical prostatectomy specimens. MATERIALS AND METHODS: Retrospective, multicentric study of 443 patients who underwent SB and TB using MRI/US fusion technique (Urostation® and Trinity®) prior to radical prostatectomy between 2010 and 2017. Cochran's Q test and McNemar test were conducted as a post hoc test. Uni-multivariable analyses were performed on several clinic-pathological variables to analyze factors predicting histopathological concordance for targeted biopsies. RESULTS: Concordance in ISUP (International Society of Urological Pathology) grade between SB, TB and SB + TB with final histopathology was 49.4%, 51.2%, and 63.2% for overall prostate cancer and 41.2%, 48.3%, and 56.7% for significant prostate cancer (ISUP grade ≥ 2), respectively. Significant difference in terms of concordance, downgrading and upgrading was found between SB and TB (ISUP grade ≥ 2 only), SB and SB + TB, TB and SB + TB (overall ISUP grade and ISUP grade ≥ 2) (p < 0.001). Total number of cores and previous biopsies were significant independent predictive factors for concordance with TB technique. CONCLUSION: In this retrospective study, combination of SB and TB significantly increased concordance with final histopathology despite a limited additional number of cores needed.

Clinical characteristics of juvenile idiopathic arthritis in an area of central Italy: a population-based study.

BACKGROUND: Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease in children and an important cause of short and long-term disability. In a recent systematic review of population based studies, the epidemiology of JIA is variable worldwide with incidence rates ranging between 1.6 and 23.0/100,000, and prevalence rates between 3.8 and 400.0/100,000. We investigate the incidence and describe the characteristics of juvenile idiopathic arthritis in the pediatric population of the central Italy, in the period 2000-2009. METHODS: A retrospective study was conducted in the Marche region to identify patients with a diagnosis of juvenile idiopathic arthritis according to ILAR criteria, between January 1, 2000 and December 31, 2009. JIA was classified according to the ILAR criteria, that is, arthritis of unknown etiology that persisted for > 6 weeks with onset before the age of 16 years. The pooled global ascertainment of cases was estimated by capture-recapture methods and two independent information sources of ascertainment of new cases of JIA were considered. RESULTS: We studied 151 patients (56 males, 37.1% and 95 females, 62.9%) meeting the ILAR criteria of juvenile idiopathic arthritis. Mean age at presentation was 6.8 ± 3.7 years for males and 6.0 ± 4.0 years for females (p=0.22). The overall incidence rate was 6.34 per 100,000/year (C.I. 6.26-7.35) and the total incidence rate increase from 2000-2009 was 8.16%. Oligoarthritis was the most common onset type (n=98, 65.0%) with 62.5% of ANA-positive patients in at least two determinations. CONCLUSIONS: Our results indicate that juvenile idiopathic arthritis incidence rates in Italy are comparable to previous data from southern Europe, with a higher frequency of oligoarthritis. To the best of our knowledge, this is the first population-based epidemiological study carried out in Italy focusing on the incidence of juvenile idiopathic arthritis.

High temperature requirement A1, transforming growth factor beta1, phosphoSmad2 and Ki67 in eutopic and ectopic endometrium of women with endometriosis.

Increasing evidence supports the hypothesis that TGFb1 signalling may be mediated by high temperature requirement A1 (HtrA1) serine protease, acting on important regulatory mechanisms such as cell proliferation and mobility. Evidence is now accumulating to suggest that HtrA1 is involved in the development and progression of several pathologies. The aim of this study was to evaluate: i) if HtrA1 and TGFb1 expressions differ in eutopic and ectopic endometrium in women with endometriosis; ii) if HtrA1 correlates to TGFb1, pSmad and Ki67. This study was carried out including 10 women with ovarian endometriosis (cases) and 10 women with non endometriotic diseases (controls). Endometrial tissue underwent immunohistochemical H-score analysis for HtrA1, TGFb1, pSmad and Ki67 molecules. Data evaluation was performed by a nonparametric Kruskal-Wallis test and Spearman correlation was applied to evaluate the relationship among the molecules investigated in the epithelial and in the stromal compartment. The HtrA1 was significant decreased in ectopic and eutopic endometrium of women with endometriosis when compared with control endometrium in epithelial compartment. TGFb1was significantly increased in eutopic endometrium and decreased in ectopic endometrium in epithelial and stromal compartment. In addition, Ki67 was significant increased and an increase, but not significant, was detected for pSMAd2 in eutopic and ectopic endometrium compared to control one.  In summary, the significant direct correlation between TGFb1 and pSmad2 as well as between HtrA1 and TGFb1 and the very significant increase of Ki67 in stromal compartment of eutopic endometrium suggest a possible involvement of HtrA1 in the pathogenesis of endometriosis.

Chinese IUD removal techniques in a Chinese population in central Italy.

OBJECTIVE: To describe routine techniques and a newly developed approach to the removal of Chinese intrauterine devices (IUs). METHODS: Office records regarding women of Chinese nationality who presented to a tertiary care hospital for IUD removal between January 2007 and March 2012 were retrieved. Their demographic data were reviewed and menstrual/obstetric history, IUD type, and reasons given for removal were recorded. All underwent pelvic transvaginal ultrasound scanning. RESULTS: Of 134 Chinese IUDs, 18 (13.4%) were removed successfully in an office setting using a hook or uterine curette without general anesthesia or cervical dilation. Extraction under brief general anesthesia was performed in 55 (41.0%) cases. A further 61 (45.5%) Chinese IUDs were successfully removed in an office setting using a miniature resectoscope. Four types of Chinese IUDs were removed, the most common being the stainless steel ring (55.7%). CONCLUSIONS: All removal procedures were effective and safe. The mini-resectoscope appears to be a safe and effective tool enabling minimally invasive surgery.

Self-sampling to increase participation in cervical cancer screening: an RCT comparing home mailing, distribution in pharmacies, and recall letter.

BACKGROUND: We performed a multicentre randomised controlled trial to evaluate the effect on participation in organised screening programmes of a self-sampling device mailed home or picked up at a pharmacy compared with the standard recall letter. METHODS: Women aged 30-64 non-responding to screening invitation were eligible. Response rate to first invitation ranged from 30% to 60% between centres. The control was the standard reminder letter to undergo the test used by the programme (Pap test in three centres and HPV DNA test in three other centres). Home mailing of the self-sampler was preceded by a letter with a leaflet about HPV. The analysis was intention-to-treat. RESULTS: In all, 14 041 women were randomised and recruited: 5012 in the control arm, 4516 to receive the self-sampler at home, and 4513 to pick up the self-sampler at a pharmacy. Participation was 11.9% in the control, 21.6% (relative participation: 1.75; 95% CI 1.60-1.93) in home, and 12.0% (relative participation: 0.96; 95% CI 0.86-1.07) in the pharmacy arms, respectively. The heterogeneity between centres was high (excess heterogeneity of that expected due to chance, i.e., I(2), 94.9% and 94.1% for home and pharmacy arm, respectively). The estimated impact on the overall coverage was +4.3% for home mail self-sampling compared with +2.2% for standard reminder. CONCLUSIONS: Home mailing of self-sampler proved to be an effective way to increase participation in screening programmes, even in those with HPV as primary testing. Picking up at pharmacies showed effects varying from centre to centre.

Burden of celiac disease in Europe: a review of its childhood and adulthood prevalence and incidence as of September 2014.

BACKGROUND: Recent epidemiological studies have demonstrated that coeliac disease (CD) prevalence is still underestimated both in Europe and in Mediterranean regions. Here we review the latest data on CD prevalence and incidence in the European Union (EU) as of September 2014. METHODS: The current epidemiological scenario of CD prevalence and incidence was investigated by searching PubMed for papers in English using the following key words: "celiac disease", "celiac disease plus prevalence" (limits: 1990-2014), "incidence" (limits: 1970-2014), and "frequency", plus "in Europe". Another search was performed with the same key words plus the name of each European country. Only prevalence data obtained by serology using anti-gliadin antibodies (AGA), EMA test, tTG test, and/or duodenal biopsy were included. The study designs considered were retrospective and prospective studies: population-based (PB), cross-sectional, case-control and cohort studies. RESULTS: Extensive research based on serological screening has demonstrated that 0.5-1% of the EU population suffers from undiagnosed CD, whereas the highest estimate reported in PB studies is approximately 1%. Considering data from different periods, incidence seems to range from 0.1 to 3.7/1000 live births in the child population and from 1.3 to 39/100,000/year in the adult population. CONCLUSIONS: The present data disclose marked geographical variation in CD incidence and prevalence in different European countries. Here we document rising CD occurrence in recent decades in European countries due partly to the advent of improved serological testing (tTG + EMA) and partly to increased awareness of its clinical presentation.

Breast cancer in European Union: an update of screening programmes as of March 2014 (review).

Breast cancer, a major cause of female morbidity and mortality, is a global health problem; 2008 data show an incidence of ~450,000 new cases and 140,000 deaths (mean incidence rate 70.7 and mortality rate 16.7, world age-standardized rate per 100,000 women) in European Union Member States. Incidence rates in Western Europe are among the highest in the world. We review the situation of BC screening programmes in European Union. Up to date information on active BC screening programmes was obtained by reviewing the literature and searching national health ministries and cancer service websites. Although BC screening programmes are in place in nearly all European Union countries there are still considerable differences in target population coverage and age and in the techniques deployed. Screening is a mainstay of early BC detection whose main weakness is the rate of participation of the target population. National policies and healthcare planning should aim at maximizing participation in controlled organized screening programmes by identifying and lowering any barriers to adhesion, also with a view to reducing healthcare costs.

Natalizumab treatment in multiple sclerosis patients: a multicenter experience in clinical practice in Italy.

We evaluated efficacy of natalizumab in relapsing-remitting multiple sclerosis patients in a clinical practice setting. We report data on the first consecutive 343 patients receiving natalizumab in 12 multiple sclerosis (MS) Italian centers enrolled between April 2007 and November 2010. The main efficacy endpoints were the proportion of patients free from relapses, disease progression, combined clinical activity, defined as presence of relapse or disease progression, from MRI activity, and from any disease activity defined as the absence of any single or combined activity. At the end of follow-up, the cumulative proportion of patients free from relapses was 68%; the proportion of patients free from Expanded Disability Status Scale (EDSS) progression was 93%; the proportion of patients free from combined clinical activity was 65%; the proportion of patients free from MRI activity was 77%; and the proportion of patients free from any disease activity was 53%. Natalizumab was effective in reducing clinical and neuroradiological disease activity. Its effectiveness in clinical practice is higher than that reported in pivotal trials and was maintained over time.

Colorectal cancer prevention in Europe: burden of disease and status of screening programs.

Colorectal cancer is a major public health challenge worldwide. In Europe it is the first malignancy in terms of incidence and the second in terms of mortality in both genders. Despite evidence indicating that removal of premalignant and early-stage cancer lesion scan greatly reduce mortality, remarkable differences are still found among countries both in terms of organized screening programs and of the tests used. In 2003 the European Council recommended that priority be given to activation of organized cancer screening programs, and various states have been making significant efforts to adopt effective prevention programs with international quality standards and centralizing screening organization and result evaluation. After a 2008 European Union report on the state of screening program, activation highlighted that little more than 50% (12/22) of Member States had colorectal cancer screening programs, Screening programs have been adopted or earlier pilot projects have been extended nationwide. This paper examines the state of activation and the screening strategies of colorectal cancer screening programs in EU States as of July 2013.

Insulin resistance in migraineurs: results from a case-control study.

OBJECTIVES: Several studies have suggested an association between migraine and insulin resistance (IR) without adequately addressing the issue according to migraine type. We assessed IR in subjects with migraine with aura (MwA) and migraine without aura (MwoA) to estimate the consistency of the possible association. METHODS: In a case-control study we included case subjects with MwA and MwoA, who were consecutively selected from those referred to our Regional Headache Center from September 2011 to February 2013, and age-matched control subjects selected using general practitioners' databases. IR was calculated by means of the homeostatic model assessment of IR (HOMA-IR), ß-cell function (HOMA-B), and the quantitative insulin sensitivity check index (QUICKI) measuring glucose and insulin values in a blood sample collected in the morning after overnight fasting. Data regarding anthropometric measures, comorbidity risk factors, and migraine characteristics were also recorded. RESULTS: We recruited 50 case subjects with MwA (38 women) and 50 with MwoA (40 women) and 50 control subjects (40 women). Proportions of arterial hypertension, cigarette smoking, hypercholesterolemia, use of oral contraceptives, and mean values of the body mass index (BMI) were similar in the three groups. We found significantly different glucose values among and within groups considering case subjects with MwA and MwoA and control subjects (4.9 ± 0.6 vs 4.7 ± 0.5 vs 4.6 ± 0.5 mmol/l; P = 0.018) in the absence of any difference in insulin (53.1 ± 24.0 vs 56.7 ± 34.4 vs 53.8 ± 24.4 pmol/l; P = 0.811), HOMA-IR (1.6 ± 0.8 vs 1.7 ± 1.0 vs 1.6 ± 0.7; P = 0.765), HOMA-B (121.4 ± 71.1 vs 149.2 ± 93.8 vs 162.8 ± 109.7; P = 0.107), and QUICKI (0.36 ± 0.03 vs 0.37 ± 0.03 vs 0.37 ± 0.03; P = 0.877) values. The logistic regression model showed increased odds of MwA in subjects exposed to the highest tertile of glucose values. This association was confirmed in the adjusted model, in which case subjects with MwA were compared with those with MwoA but not with control subjects. CONCLUSIONS: In contrast to what has been shown by the majority of the available studies, the results of our study do not support the association of migraine with IR. As our study was not population-based and several patients had low disease activity, these findings need further confirmation.

Alterations of maternal plasma HTRA1 level in preeclampsia complicated by IUGR.

We evaluated the presence of HtrA1 in maternal plasma of normal pregnancies and of pregnancies complicated by preeclampsia (PE) without and with Intrauterine Growth Restriction (IUGR). We demonstrate that HtrA1 maternal plasma levels show significant different concentrations in first, second and third trimester of gestation and that HtrA1 concentration increases in maternal plasma of gestations complicated by PE with IUGR compared with control maternal plasma matched for gestational age. Based on these data high maternal plasma levels of HtrA1 could be considered as a possible marker of an occurring IUGR in preeclamptic women.

Current psoriasis treatments in an Italian population and their association with socio-demographical and clinical features.

BACKGROUND: Patient adherence is a key element for therapeutic success and represents a major concern for all healthcare professionals. OBJECTIVE: Aim of our study was to assess the frequency of use of treatments currently available for psoriasis and its association with specific socio-demographical and clinical variables. METHODS: The study population consisted of 1689 patients, aged 12-85 years. Information concerning socio-demographical variables, clinical features and the type of current treatment was collected. Items on patients' satisfaction of current treatments and of dermatologist-patient relationship were also included. The chi-squared test was used to estimate the association between the categorical variables, whereas Wilcoxon and Kruskal-Wallis tests were applied to the interval and ordinal variables. The Cochran-Mantel-Haenszel chi-squared trend test was used to evaluate the degree of satisfaction related to dermatologist-patient relationship. RESULTS: Of the 1689 psoriatic patients, 54.1% did not use any treatments and 45.9% used at least one treatment. The use of drugs was significantly associated exclusively to severity of disease and affected body surface area. Systemic therapies, both traditional treatments and biological agents, were mainly used in patients with disease duration >10 years and disease severity. Treatment adherence was significantly associated to the degree of patient's satisfaction of his/her relationship with the dermatologist. Alternative treatment such as over the counter medications and acupuncture were used by 33% of patients. CONCLUSION: The majority of psoriatic patients do not use any treatments. However, treatment adherence significantly increases when dermatologists clarify the treatment schedule, inform patients and meet the patients' needs.

Vascular patterns in basal cell carcinoma.

BACKGROUND: Dermoscopy has been proved to increase the diagnostic accuracy of basal cell carcinoma (BCC). OBJECTIVE: To characterize the type and frequency of vascular patterns in superficial and nodular BCCs. METHODS: We retrospectively analysed the dermoscopic images of 504 histopathologically proven BCCs. RESULTS: The most common vascular pattern was represented by arborizing vessels (306/504; 60.7%), which were significantly more frequent in nodular BCCs (nBCCs) compared with superficial BCCs (sBCCs), and in pigmented sBCCs vs. non-pigmented sBCCs (P<0.0001). Short fine telangectasias (SFTs) were found in 33.1% (167/504) of cases and were significantly more frequent in sBCCs compared with nBCCs (P<0.0001). Hairpin vessels were detected in 52/504 (10.3%) BCCs. Minor vascular patterns included glomerular vessels (41/504; 8.1%), dotted (21/504; 4.2%), comma vessels (5/504; 1.0%) and polymorphous pattern (9/504; 1.8%). CONCLUSIONS: Arborizing vessels are prototypic of nBCCs, whereas SFTs are characteristics of sBCCs. Differential diagnosis with squamous cell carcinoma or melanoma is mandatory when a polymorphous pattern is detected.

[Research Ethics Committees in Abruzzo: criticisms and prospects for developments]. / I Comitati etici abruzzesi: criticità rilevate e prospettive di sviluppo.

The first legislative bills on Ethics Committee (EC) activity were adopted across the Italian Regions simultaneously (1998). This widespread implementation meant it was necessary to define new qualitative and quantitative standards (Decree Law, 12th May 2009), creating expectations about the EC's role in research and clinical practice and its potential to improve the quality of medical assistance. The present paper presents the results of a descriptive survey that maps out the framework, organization and operating methods of ECs in the Abruzzo Region in Italy. Differences between ECs have been outlined, with special concern for differences in organization and way of operating. It was found that interaction between the EC and the experimenter is limited to the authorization phase of the research protocol, with low level involvement in the planning and execution phases. Additionally, the exchange of information between the co-ordinating EC and EC practitioners is not well organized in multicentre experimentation. A certain amount of criticism emerged regarding those areas of activity that would help to place the EC at the centre of the cultural growth process with regards to Bioethics and Clinical Research (e.g. education, on-line news on Bioethics topics).These criticisms are part of the reality of the Abruzzo Region that lacks economic and structural resources which penalizes EC activity.

Afebrile benign convulsions with mild gastroenteritis: a new entity?

Afebrile seizures in children usually necessitate investigations in order to determine the etiology and estimate the prognosis. Recently, convulsions that are described as benign but afebrile have been documented in children, in association with diarrhea, and are now recognized as a distinct entity. Benign afebrile seizures with mild gastroenteritis are defined as convulsions accompanying symptoms of mild diarrhea without dehydration or electrolyte derangement and without fever before and after the seizures in healthy children without meningitis, encephalitis or encephalopathy. The convulsions are short, symmetrical, generalized tonic-clonic seizures, occurring in clusters. Laboratory studies (full blood count, blood glucose, creatinine, serum electrolytes, cerebrospinal fluid, bacterial and viral cultures) are usually normal, and other investigations (neuroimaging and electroencephalogram) are not necessary. Prognosis is always favorable (normal psychomotor development, no recurrences of seizures), and anticonvulsant therapy is not warranted. Recognition of this benign infantile convulsion avoids extensive evaluation and long-term anticonvulsant therapy; physicians may reassure the parents regarding the lack of long-term sequelae. In conclusion, this type of seizure seems to be a new entity, but it awaits a correct place in the large group of infantile convulsion disorders.

CD1a and CD1e allele frequencies in an Italian population from the Abruzzo region.

CD1 is a small family comprising 5 MHC-like genes located on chromosome 1 and encoding glycoproteins termed CD1a, CD1b, CD1c, CD1d and CD1e. They are expressed mainly on the surface of dendritic cells, monocytes and some thymocytes and are specialized in presenting lipid antigens to T lymphocytes. The structure is similar to that of MHC class I molecules with 3 globular domains and the Beta2-microglobulin. It has been shown that all five human CD1 genes exhibit a limited number of polymorphisms in the alpha1 domain whose effects are still unknown. CD1e results to be the most polymorphic isoform with six CD1e alleles (01, 02 in exon 2 and 03, 04, 05, 06 in ex3) described to date. At this moment, few investigations on the allele frequencies of the CD1 genes have been reported and all additional information improves our knowledge on this new class of antigen-presenting molecules. In order to study possible allelic variations of exon 2 of human CD1a and CD1e genes, we analyzed, by a sensitive technique, the sequence-based typing (SBT), 114 DNA samples from unrelated healthy Italian individuals from the Abruzzo region. Our experimental findings indicate that the allele frequency distribution of both CD1a and CD1e genes is in accordance with that observed in other geographic areas and did not identify any new allele, thus confirming a very low polymorphism.
