Cardiac implantable electronic devices can accurately detect AF as AHRE. Atrial high rate episodes were associated to a higher incidence of silent IBL on CT scan. Atrial high rate episodes represent a kind of silent AF where management recommendations are lacking despite the fact that a higher embolic risk is present.

Background/Aims A single best endpoint for evaluating treatments of severe influenza requiring hospitalization has not been identified. A novel six-category ordinal endpoint of patient status is being used in a randomized controlled trial (FLU-Intravenous Immunoglobulin - FLU-IVIG) of intravenous immunoglobulin. We systematically examine four factors regarding the use of this ordinal endpoint that may affect power from fitting a proportional odds model: (1) deviations from the proportional odds assumption which result in the same overall treatment effect as specified in the FLU-IVIG protocol and which result in a diminished overall treatment effect, (2) deviations from the distribution of the placebo group assumed in the FLU-IVIG design, (3) the effect of patient misclassification among the six categories, and (4) the number of categories of the ordinal endpoint. We also consider interactions between the treatment effect (i.e. factor 1) and each other factor. Methods We conducted a Monte Carlo simulation study to assess the effect of each factor. To study factor 1, we developed an algorithm for deriving distributions of the ordinal endpoint in the two treatment groups that deviated from proportional odds while maintaining the same overall treatment effect. For factor 2, we considered placebo group distributions which were more or less skewed than the one specified in the FLU-IVIG protocol by adding or subtracting a constant from the cumulative log odds. To assess factor 3, we added misclassification between adjacent pairs of categories that depend on subjective patient/clinician assessments. For factor 4, we collapsed some categories into single categories. Results Deviations from proportional odds reduced power at most from 80% to 77% given the same overall treatment effect as specified in the FLU-IVIG protocol. Misclassification and collapsing categories can reduce power by over 40 and 10 percentage points, respectively, when they affect categories with many patients and a discernible treatment effect. But collapsing categories that contain no treatment effect can raise power by over 20 percentage points. Differences in the distribution of the placebo group can raise power by over 20 percentage points or reduce power by over 40 percentage points depending on how patients are shifted to portions of the ordinal endpoint with a large treatment effect. Conclusion Provided that the overall treatment effect is maintained, deviations from proportional odds marginally reduce power. However, deviations from proportional odds can modify the effect of misclassification, the number of categories, and the distribution of the placebo group on power. In general, adjacent pairs of categories with many patients should be kept separate to help ensure that power is maintained at the pre-specified level.

Although AutoCapture algorithm has shown both efficacy and safety, our findings suggest that some patients with atrial fibrillation or those requiring ventricular pacing ≤25% of the time may not benefit from it. Activation of the algorithm should be individualized according to the patient's characteristics and long-term AutoCapture pattern checked in the routine follow-up.

Keywords: common variable immunodeficiency • granulomatous lymphocytic interstitial lung disease • autoimmune hemolytic anemia • idiopathic thrombocytopenic purpura • pulmonary function tests Abstract: Granulomatous Lymphocytic Interstitial Lung Disease (GLILD) is an inflammatory pulmonary complication of common variable immunodeficiency (CVID) with distinctive patterns in the biopsy; Granulomatous Disease, Lymphocytic Interstitial Disease, Follicular Bronchiolitis and Organizing Pneumonitis. Without the proper treatment this complication will lead to important pulmonary dysfunction due to fibrosis. Although this process has been well recognized, protocols for a standardized treatment, and the proper timing for the use of immune modulation as well as the maintenance time with monoclonal antibodies are an unclear topic.Case presentation: We present the case of a 57-year-old female patient with CVID. During the evaluation of an episode of autoimmune hemolytic anemia, she presented concomitantly radiological and histopathological features of GLILD. She was treated successfully with Rituximab monotherapy without any complications and is currently asymptomatic. Conclusion:We conclude that the use of Rituximab as single therapy, modulates the lymphocytic infiltration of the lung parenchyma and stops the progression and organization of the damage mediated by B cells and indirectly by T cells, and it could be used as monotherapy in the proper timing of the diagnostic process.

HL—A phenotype frequencies were studied in 30 patients with leprosy and in 149 healthy controls. Leprosy patients had a significantly higher frequency of HL—A14. In addition, a majority of the HL—A14 patients gave a negative response to leproma antigen using the Mitsuda test.

Background: Off-label use of intravenous immunoglobulin has been reported for the treatment of recurrent spontaneous pregnancy loss and selected cases of multiple sclerosis.However, the use of subcutaneous immunoglobulin has not been reported in these settings.
