Sustained low influenza vaccination in health care workers after H1N1 pandemic: a cross sectional study in an Italian health care setting for at-risk patients.

BACKGROUND: Despite consistent recommendations by all Public Health Authorities in support of annual influenza vaccination for at-risk categories, there is still a low uptake of influenza vaccine in these groups including health care workers (HCWs). Aim of this observational two-phase study was to estimate the immunization rates for influenza in four subsequent seasons and for pandemic H1N1 influenza in HCWs of a University Hospital, and to investigate its distribution pattern and the main determinants of immunization. Phase 1 data collection was performed in 2009-2010, during the peak of H1N1 pandemic. Phase 2 data collection, aimed to investigate seasonal influenza vaccination coverage in the three seasons after pandemic, was performed in 2012-2013. METHODS: The overall H1N1 vaccination rate was derived by the Hospital immunization registry. In 2010, the personnel of three Departments (Infectious Diseases, Pediatrics and Gynecology/Obstetrics) completed a survey on influenza. A second-phase analysis was performed in 2012 to investigate influenza vaccination coverage in three consecutive seasons. RESULTS: The first-phase survey showed a low coverage for influenza in all categories (17 %), with the lowest rate in nurses (8.1 %). A total of 37 % of health care workers received H1N1 vaccine, with the highest rate among physicians and the lowest in nurses. H1N1 vaccination was closely related to the Department, being higher in the Department of Infectious Diseases (53.7 %) and Pediatrics (42.4 %) than in Gynecology/Obstetrics (8.3 %). The second-phase survey showed the lowest rate of influenza vaccination in 2012/13 season. The main reasons for not being vaccinated were "Unsure of the efficacy of vaccine" and "Feel not at-risk of getting influenza or its complications". Despite recommendations, influenza vaccine uptake remains poor. CONCLUSION: Immunization is largely perceived as a personal protection rather than a measure needed to prevent disease spreading to at-risk patients. Compulsory vaccination against influenza should be considered as a possible strategy, at least in health institutions where at-risk patients are admitted.

A retrospective evaluation of the association of celiac disease and growth hormone deficiency: more than a casual association?

BACKGROUND: A transient dysfunction of the endocrine growth axis has been reported in celiac disease (CD). This apparent growth hormone deficiency (GHD) generally normalizes with the institution of a gluten-free diet (GFD). However, in few cases, the dysfunction of the GH axis persists despite a good adherence to the GFD. Aims of this study were to investigate pediatric patients with concurrent CD and GHD and to compare them with patients with isolated CD. METHODS: Data regarding CD patients with and without associated GHD were retrospectively collected. Inclusion criteria were availability of anthropometric and laboratory data at baseline and regularly at the reference center up to a 2-year follow-up. In case of poor catch-up growth despite a good adherence to the GFD, endocrinological investigation was carried on. RESULTS: Fifty-three patients with CD were included. Four (7.5%) out of 53 CD patients had a concurrent GHD. In two cases, firstly diagnosed with CD, GHD was suspected because of a poor catch-up growth despite a good adherence to the GFD. In two other cases, firstly diagnosed with GHD, gastrointestinal symptoms revealed the diagnosis of CD. Normalization of height velocity was achieved by GH treatment in all cases. No statistical significant difference between the two groups of patients was found as regard laboratory and histological features of CD. It is to note that 2 out of 4 patients with concomitant CD and GHD had thyroiditis compared to 6% of patients with isolated CD (P=0.004). CONCLUSIONS: A high prevalence of CD and GHD association was found. CD patients with poor catch-up growth despite a good adherence to the GFD should be carefully investigated for endocrine disorders.
