The main objective is to evaluate HbA1c levels in patients with cystic fibrosis-related diabetes (CFRD) after one-year of therapy with elexacaftor/tezacaftor/ivacaftor (ETI). The secondary objective is to study the changes in total daily insulin dose (TDD), pulmonary function and metabolism in this population. A retrospective sin gle-center observational study was conducted at Regional Cystic Fibrosis Centre and Diabetology Centre of IRCCS Istituto Giannina Gaslini. The observation period was divided into Time 0 (ETI treatment initiation), Time 1 (T1 – 3 months of ETI therapy), Time 2 (T2 - 6 months of therapy) and Time 3 (T3 - 12 months of therapy). Demographic and clinical data were collected. The results were then stratified by genotype (F508del in homozygosity or heterozygosity). Twenty-eight patients with CFRD undergoing insulin therapy were included. TDD (IU) significantly decreased at T1 and T2, but not at T3, as for HbA1c. The number of hospitalizations and pulmonary exacerbations decreased significantly. We demonstrated both improvement in glycemic control (by means of HbA1c) and insulin requirement in insulin dependent CFRD patients after one year of only ETI treatment.

Grapevine is one of the most relevant crops in the world being used for economically important products such as wine. Yet, relevant grapevine cultivars are heavily affected by diseases such as the downy mildew disease caused by Plasmopara viticola. Improvements on grapevine resistance are made mainly by breeding techniques where resistance traits are introgressed into cultivars with desired grape characteristics. However, there is still a lack of knowledge on how resistant or tolerant cultivars tackle the P. viticola pathogen. In this study, using a shotgun proteomics LC-MS/MS approach, we unravel the protein modulation of a highly tolerant grapevine cultivar, V. vinifera ‘Regent’, in the first hours post inoculation (hpi) with P. viticola. At 6 hpi, proteins related to defence and to response to stimuli are negatively modulated while at 12 hpi there is an accumulation of proteins belonging to both categories. The co-occurrence of effector-triggered susceptibility (ETS) and effector-triggered immunity (ETI) is detected at both time-points, showing that these defence processes present high plasticity. The results obtained in this study unravel the tolerant grapevine defence strategy towards P. viticola and may provide valuable insights on resistance associated candidates and mechanisms, which may play an important role in the definition of new strategies on breeding approaches.
