Spanish national registry of celiac disease: incidence and clinical presentation.

OBJECTIVES: The aim of this study was to assess the incidence and clinical pattern of celiac disease (CD) presently diagnosed in Spanish children. METHODS: A prospective, multicenter, nationwide registry of new cases of CD in children <15 years was conducted from June 1, 2006 to May 31, 2007. The parameters studied were age at diagnosis, sex, clinical symptoms, associated diseases, nutritional status, CD serology, histological lesions, and HLA-DQ2/-DQ8. The crude incidence rate of CD was calculated as new cases per 1000 live births and as new cases per 100,000 person-years <15 years of age. RESULTS: A total of 974 new cases of CD were included. The median age at diagnosis was 2.3 years; 39.5% of CD diagnoses occurred in the first 2 years, 42% between 2 and 6, and 18.4% from 6 to 15. Total number of cases in each age group was 385, 409, and 180, respectively. Regarding clinical presentation 70.9% showed classical symptoms, 21.9% were nonclassical, and 7% were asymptomatic. A total of 95.7% of 931, 94.7% of 611, and 86.7% of 651 children tested positive, respectively, for immunoglobulin A (IgA) anti-transglutaminase type 2 antibodies, IgA endomysial antibodies, and IgA anti-gliadin antibodies. Villous atrophy was observed in 92.4% and increased intraepithelial lymphocytes with crypt hyperplasia in 3.3%. Of the children, 55% had normal growth, and 3.4% were overweight. The HLA phenotype was DQ2: 88.3%, DQ2/DQ8: 8.4%, and DQ8: 2.3%. The incidence rate was 7.9 cases of CD per 1000 live births and 54 cases per 100,000 person-years. CONCLUSIONS: In Spain, the most frequent clinical presentation of CD is the classical form, mainly diagnosed during the first 2 years of life. The observed incidence of CD in Spanish children is much higher than the present CD incidence rates observed in other European countries.

"Geographical distribution of risk genotypes in pediatric patients with celiac disease in Spain".

Celiac disease is strongly associated with HLA DQ, specifically with haplotypes. DRB1*03-DQA1*05:01/DQB1*02:01 (DQ2.5),DRB1*07-DQA1*02:01/DQB1*02:02 (DQ2.2), DRB1*11-DQA1*05:05/DQB1*03:01 (DQ7.5), and DRB1*04-DQA1*03:01/DQB1*03:02 (DQ8). The distribution of these risk haplotypes in patients with celiac disease is different in the geographical areas investigated. A high frequency of DRB1*07- DQA1*02:01/DQB1*02:02 (DQ2.2) and DRB1*11-DQA1*05:05/DQB1*03:01 (DQ7.5), has been described in Southern Europe. We analyzed 2102 confirmed CD cases with information on both DQB1* alelles and their distribution by geographical area in Spain. According to the presence of this haplotype in one or two chromosomes, the genotype is classified in: DQ2 homozygous, DQ2 heterozygous (cis or trans), DQ8 homozygous, DQ8/DQ2.5, DQ 2.2 homozygous and genotype known as "half DQ2". Two different patterns of risks related to CD were identified. In the Basque Country and Navarre, the Mediterranean Area (Aragon, Catalonia, Valencia, Balearic Islands, and Murcia), the South of Spain (Andalucía and Extremadura), and the Canary Islands, higher frequency of DQ2.5 trans, and more than 80% of DQ2.5/DQ2.2 homozygosis were described. The Cantabrian Coast (Cantabria, Asturias, and Galicia) and Central Areas (Castilla-León and Castilla-La Mancha) showed a higher percentage of DQ2.5/DQ2.5 homozygosis and a lower DQ2.5 in trans frequency, as in Northern Europe. Madrid has an intermediate model between the two described above. 17 cases (0.8%) did not carry any CD risk haplotypes.

[Compliance evaluation of "do not do" recommendations of the Spanish Society of Preventive Medicine and public health]. / Evaluación del cumplimiento de las recomendaciones de "no hacer" de la Sociedad Española de Medicina Preventiva y Salud Pública.

OBJECTIVE: The reduction of unnecessary health interventions determines good care quality. The objective of this work was to evaluate the compliance of the "do not do" recommendations proposed by the Spanish Society of Preventive Medicine, Public Health and Hygiene. METHODS: Prospective, observational, descriptive study of patients admitted to the La Princesa University Hospital between December 2018 and January 2019. The compliance of each recommendation in different patients was analyzed. The quantitative variables are expressed as means and standard deviation and the qualitative values as percentages and confidence interval. RESULTS: In Recommendation 1 (R1: "Do not remove hair systematically"), 231 interventions were studied and the compliance was of 100% (95% CI: 98.27-100). In Recommendation 2 (R2: "Do not maintain antibiotics for more than 48 hours, unless evidence of infection"), 201 interventions were studied and the compliance was of 93.53% (95% CI: 90.09-96.91). In Recommendation 3 (R3: "Do not analyze C. difficile toxin in asymptomatic patients"), 200 determinations were studied and the compliance was of 93.5% (95% CI: 90.08-96.92). In Recommendation 4 (R4: "Do not do routine nasal decolonization"), 167 interventions were recruited and the compliance was of 100% (95% CI: 97.6-100). In Recommendation 5 (R5: "Do not perform routine replacement of peripheral venous catheter every 72-96 hours"), 153 patients were studied in compliance with the recommendation of 98.04% (95% CI: 94.12-99.35). CONCLUSIONS: A 100% compliance was found in Recommendations 1 and 4. There is an opportunity of improvement in the recommendations R2, R3 and R5.

OBJETIVO: La reducción de las intervenciones sanitarias innecesarias, bien porque no han demostrado su eficacia, bien porque poseen efectividad dudosa o no son eficientes, mejora la calidad de la atención sanitaria. El objetivo de este trabajo fue evaluar el grado de cumplimiento de las recomendaciones consensuadas por la Sociedad Española de Medicina Preventiva, Salud Pública e Higiene para el proyecto "No hacer". METODOS: Se realizó un estudio prospectivo, observacional y descriptivo de pacientes ingresados en el Hospital Universitario de La Princesa entre diciembre de 2018 y enero de 2019. Se evaluó el cumplimiento de cada recomendación en diferentes pacientes. Se calcularon porcentajes e intervalos de confianza en las variables cualitativas y el las cuantitativas la media y desviación estándar. RESULTADOS: En la Recomendación 1 (R1: "No eliminar el vello de forma sistemática"), se estudiaron 231 intervenciones y el cumplimiento de la recomendación fue del 100% (IC95%: 98,27-100%). En la Recomendación 2 (R2: "No continuar con antibióticos más de 48 horas, a menos que haya evidencia de infección"), se estudiaron 201 intervenciones y el cumplimiento de la recomendación fue del 93,53% (IC95%: 90,09-96,91%). En la Recomendación 3 (R3: "No realizar análisis de toxina C. difficile en pacientes asintomáticos"), se estudiaron 200 determinaciones y el cumplimiento fue del 93,5% (IC95%: 90,08-96,92%). En la Recomendación 4 (R4: "No utilizar descontaminante nasal rutinario"), se reclutaron 167 intervenciones y el cumplimiento fue del 100% (IC95%: 97,6-100%). En la Recomendación 5 (R5: "No reemplazo rutinario de catéter venoso periférico cada 72-96 horas"), se estudiaron 153 pacientes con un cumplimiento de 98,04% (IC95%: 94,12-99,35%). CONCLUSIONES: Se comprueba un cumplimiento del 100% en las Recomendaciones 1 y 4. Hay oportunidad de mejora en las recomendaciones R2, R3 y R5.
