EAACI position paper on diet diversity in pregnancy, infancy and childhood: Novel concepts and implications for studies in allergy and asthma
To fully understand the role of diet diversity on allergy outcomes and to set standards for conducting research in this field, the European Academy of Allergy and Clinical Immunology Task Force on Diet and Immunomodulation has systematically explored the association between diet diversity and allergy outcomes. In addition, a detailed narrative review of information on diet quality and diet patterns as they pertain to allergic outcomes is presented. Overall, we recommend that infants of any risk category for allergic disease should have a diverse diet, given no evidence of harm and some potential association of benefit in the prevention of particular allergic outcomes. In order to harmonize methods for future data collection and reporting, the task force members propose relevant definitions and important factors for consideration, when measuring diet diversity in the context of allergy. Consensus was achieved on practice points through the Delphi method. It is hoped that the definitions and considerations described herein will also enable better comparison of future studies and improve mechanistic studies and pathway analysis to understand how diet diversity modulates allergic outcomes
HIV sero-prevalence among tuberculosis patients in Kenya
Objective: To determine HIV seroprevalence among tuberculosis patients and the burden of HlV attributable tuberculosis among notified patients in Kenya.Design: A cross-sectional anonymous unlinked HlV seroprevalence survey.Setting: Tuberculosis diagnostic clinics of the National Leprosy Tuberculosis Programme in 19 districts.Subjects: One thousand nine hundred and fifty two newly notified tuberculosis patients.Interventions: Selection and registration of eligible subjects followed by obtaining 5ml of full blood for haemoglobin testing and separation of serum for HIV testing by ELISA.Main outcome measures: HlV seroprevalence per district and burden of HIV attributable tuberculosis among tuberculosis patients.Results: A total of 1,952 eligible patients were ended. The weighted seroprevalence in the sample was 40.7% (range 11.8-79.6% per district). The seroprevalence was significantly higher among females and patients with sputum-smear negative tuberculosis. Chronic diarrhoea, female sex, oral thrush and a negative sputum were independent risk factors for HIV infection. The Odds ratio for HIV infection in female tuberculosis patients aged 15-44 years, was 5.6 (95% CI 4.5-6.9) compared with ante-natal clinic attenders. The population attributable risk was 0.22 in 1994.Conclusion: The HlV epidemic has had a profound impact on the tuberculosis epidemic in Kenya and explains about 41% of the 94.5% increase of registered patients in the period 1990-1994 and 20% of all registered patients in 1994. Repetition of the survey with inclusion of a more representative control group from the general population may provide a more accurate estimation of the burden of HIV attributable tuberculosis
