In response to the coronavirus pandemic 2019 (COVID-19), Italy established the national school closings from March 5, 2020. It has been shown that during school closures, there are significant ...decreases in the diagnoses of the respiratory infections. This has brought as well to a reduction in all those symptoms related to adenotonsillar hypertrophy.
The study included 162 children, aged between 3 and 13 years, waiting for adenoidectomy and/or tonsillectomy, eventually combined with tympanocentesis or tube insertion. Parents have been called to answer a telephone interview aimed at detecting how the symptoms related to adenotonsillar hypertrophy were changing during lockdown.
There was an improvement in the overall symptomatology of children during the lockdown period. The value attributed by parents to the children's general assessment during the lockdown period decreased significatively during the quarantine (p = 0,0000).
The present study demonstrates that lockdown can have a positive impact on those specific diseases derived from precocious socialization and that it results to be particularly effective for the most vulnerable children. Indeed, lockdown has resulted to be so efficient that it has caused a modification in a medical and surgical therapeutic indication.
Ocrelizumab is a novel humanized anti-CD20 antibody used for treatment of relapsing remitting and primary progressive multiple sclerosis with evidence of inflammatory activity. Guidelines suggest ...assessing vaccination status and eventually vaccinate patients with multiple sclerosis before new disease modifying therapy initiation. However, there are not any specific recommendations about vaccinal immunity reassessment after ocrelizumab injection. We describe the case of a patient who loss varicella zoster vaccinal immunity after the first ocrelizumab infusion. It is advisable to reassess vaccinal immunity to isolate non-immune patients and to adopt suitable preventive measures, including close contacts vaccination and avoidance of contacts with active infection.
•Vaccination should be updated before any DMT.•Live-attenuated vaccines are contraindicated during immunosuppression and, of course, during anti-CD20 treatment.•Immunization decreases over age.•Cocooning strategy should be recommended in case of contraindication for updating vaccinations in negative patients.•Anti CD-20 treatment decreases vaccines efficacy.
Aims
Pompe disease is an autosomal recessive lysosomal storage disorder resulting from deficiency of acid α‐glucosidase (GAA) enzyme. Histopathological hallmarks in skeletal muscle tissue are fibre ...vacuolization and autophagy. Since 2006, enzyme replacement therapy (ERT) is the only approved treatment with human recombinant GAA alglucosidase alfa. We designed a study to examine ERT‐related skeletal muscle changes in 18 modestly to moderately affected late onset Pompe disease (LOPD) patients along with the relationship between morphological/biochemical changes and clinical outcomes. Treatment duration was short‐to‐long term.
Methods
We examined muscle biopsies from 18 LOPD patients at both histopathological and biochemical level. All patients underwent two muscle biopsies, before and after ERT administration respectively. The study is partially retrospective because the first biopsies were taken before the study was designed, whereas the second biopsy was always performed after at least 6 months of ERT administration.
Results
After ERT, 15 out of 18 patients showed improved 6‐min walking test (6MWT; P = 0.0007) and most of them achieved respiratory stabilization. Pretreatment muscle biopsies disclosed marked histopathological variability, ranging from an almost normal pattern to a severe vacuolar myopathy. After treatment, we detected morphological improvement in 15 patients and worsening in three patients.
Post‐ERT GAA enzymatic activity was mildly increased compared with pretreatment levels in all patients. Protein levels of the mature enzyme increased in 14 of the 18 patients (mean increase = +35%; P < 0.05). Additional studies demonstrated an improved autophagic flux after ERT in some patients.
Conclusions
ERT positively modified skeletal muscle pathology as well as motor and respiratory outcomes in the majority of LOPD patients.
In the United States, the frequency of using percutaneous mechanical circulatory support devices for acute myocardial infarction complicated by cardiogenic shock is increasing. These devices require ...large-bore vascular access to provide left, right, or biventricular cardiac support, frequently under urgent/emergent circumstances. Significant technical and logistical variability exists in device insertion, care, and removal in the cardiac catheterization laboratory and in the cardiac intensive care unit. This variability in practice may contribute to adverse outcomes observed in centers that receive patients with cardiogenic shock, who are at higher risk for circulatory insufficiency, venous stasis, bleeding, and arterial hypoperfusion. In this position statement, we aim to: 1) describe the public health impact of bleeding and vascular complications in cardiogenic shock; 2) highlight knowledge gaps for vascular safety and provide a roadmap for a regulatory perspective necessary for advancing the field; 3) propose a minimum core set of process elements, or “vascular safety bundle”; and 4) develop a possible study design for a pragmatic trial platform to evaluate which structured approach to vascular access drives most benefit and prevents vascular and bleeding complications in practice.
Display omitted
•Major bleeding and vascular complications are common in patients with AMI complicated by cardiogenic shock and contribute to morbidity and mortality.•There is substantial variability in practice relating to vascular access, cardiac critical care delivery, device removal, and vascular closure among institutions and individual operators.•Standardization of vascular access and closure techniques and approach to cardiac critical care management using “safety bundles” have the potential to favorably impact health outcomes during cardiogenic shock care.
Chronic pancreatitis (CP) is associated with elevated plasma levels of bacterial lipopolysaccharide (LPS) and we have demonstrated reduced acinar cell autophagy in human CP tissue. Therefore, we ...investigated the role of autophagy in experimental endotoxin-induced pancreatic injury and aimed to identify LPS in human CP tissue. Pancreatic Atg7-deficient mice were injected with a single sub-lethal dose of LPS. Expression of autophagy, apoptosis, necroptosis, and inflammatory markers was determined 3 and 24 h later utilizing immunoblotting and immunofluorescence. The presence of LPS in pancreatic tissue from mice and from patients and healthy controls was determined using immunohistochemistry, immunoblots, and chromogenic assay. Mice lacking pancreatic autophagy exhibited local signs of inflammation and were particularly sensitive to the toxic effect of LPS injection as compared to control mice. In response to LPS, Atg7
mice exhibited enhanced vacuolization of pancreatic acinar cells, increase in TLR4 expression coupled to enhanced expression of NF-κΒ, JNK, and pro-inflammatory cytokines by acinar cells and enhanced infiltration by myeloid cells (but not Atg7
controls). Cell death was enhanced in Atg7
pancreata, but only necroptosis and trypsin activation was further amplified following LPS injection along with elevated pancreatic LPS. The presence of LPS was identified in the pancreata from all 14 CP patients examined but was absent in the pancreata from all 10 normal controls. Altogether, these results support a potential role for metabolic endotoxemia in the pathogenesis of CP. Moreover, the evidence also supports the notion that autophagy plays a major cytoprotective and anti-inflammatory role in the pancreas, and blunting metabolic endotoxemia-induced CP.
The role of pancreatic acinar cells in initiating necro-inflammatory responses during the early onset of alcoholic acute pancreatitis (AP) has not been fully evaluated. We investigated the ability of ...acinar cells to generate pro- and anti-inflammatory mediators, including inflammasome-associated IL-18/caspase-1, and evaluated acinar cell necrosis in an animal model of AP and human samples. Rats were fed either an ethanol-containing or control diet for 14 weeks and killed 3 or 24 h after a single lipopolysaccharide (LPS) injection. Inflammasome components and necro-inflammation were evaluated in acinar cells by immunofluorescence (IF), histology, and biochemical approaches. Alcohol exposure enhanced acinar cell-specific production of TNFα, IL-6, MCP-1 and IL-10, as early as 3 h after LPS, whereas IL-18 and caspase-1 were evident 24 h later. Alcohol enhanced LPS-induced TNFα expression, whereas blockade of LPS signaling diminished TNFα production in vitro, indicating that the response of pancreatic acinar cells to LPS is similar to that of immune cells. Similar results were observed from acinar cells in samples from patients with acute/recurrent pancreatitis. Although morphologic examination of sub-clinical AP showed no visible signs of necrosis, early loss of pancreatic HMGB1 and increased systemic levels of HMGB1 and LDH were observed, indicating that this strong systemic inflammatory response is associated with little pancreatic necrosis. These results suggest that TLR-4-positive acinar cells respond to LPS by activating the inflammasome and producing pro- and anti-inflammatory mediators during the development of mild, sub-clinical AP, and that these effects are exacerbated by alcohol injury.
Intravesical instillation of Bacille Calmette-Guèrin (BCG) is the standard adjuvant treatment for high-risk non muscle invasive bladder cancer (NMIBC). Since its mechanism of action is supposed to be ...linked to the immune system efficiency and senescence could negatively affect this efficiency, BCG efficacy in the elderly has been questioned. This study aimed to assess the impact of age on BCG efficacy and safety in patients with high-grade T1 bladder cancer (BC).Among 123 patients with high-grade T1 BCG scheduled for BCG treatment, 82 were <75 year-old (group A) and 41 were ≥75 year-old (group B). Follow-up: urine cytology and cystoscopy every 3 months for the first 2 years, every 6 months for the third year, and then yearly. Tumor recurrence was defined as pathological evidence of disease at the bladder biopsy; tumor progression was defined as pathological shift to muscle invasive disease at the bladder biopsy or the imaging techniques showing recurrent BC and distant metastasis likely related to it.The median follow-up was 65 months (range 11-152). Recurrence occurred in 35 patients, 19 (23.2%) in the group A and 16 (39%) in the group B. Progression occurred in 18 patients, 12 (14.6%) in the group A and 6 (14.6%) in the group B. Recurrence free rate was similar in both groups up to 2 years. The 5 years progression rate was almost the same in both groups A and B (85.9% vs 84.7%), whereas the 5 years cancer-specific survival (CSS) was 92.6% in the group A and 85.4% in the group B. Of the 18 patients with progression, 11 underwent cystectomy; 12 patients died because of their BC. Kaplan-Meier plots pointed out no difference in recurrence-free, progression-free, and CSS between the 2 groups. Adverse events were similar in the 2 groups. Only 4 (3.3%) patients, 2 (2.4%) in the group A and 2 (4.8%) in the group B, experienced mild adverse reactions compatible with treatment.Elderly patients with high-grade T1 BC are not poorer candidates to BCG treatment, as they had similar benefit and adverse reactions than those aging ≥75 years.
Background and purpose
The purpose of this study was to determine whether switching from branded levetiracetam (Keppra®) to a levetiracetam generic equivalent product (Matever®) in an epilepsy cohort ...could provide adequate results in terms of seizure control and tolerability.
Methods
To be eligible for the study, patients had to have been taking Keppra® as monotherapy or polytherapy for at least 6 months. Between March 2013 and April 2017, patients were invited to switch to Matever® as part of their follow‐up. We evaluated the number of seizures per month, drug‐related adverse events and electroencephalography before the switch (T0, baseline) and 6 months after switching (T1). Furthermore, we reported the long‐term follow‐up of patients who continued to use Matever® after the end of the study, considering the most recent visit for each patient (T2).
Results
A total of 55 patients refused the switch. Among the remaining 125 patients, 59 (47%) were treated using Keppra® as monotherapy and 66 (53%) were on Keppra® as polytherapy. All 125 patients were subjected to switching from Keppra® to Matever®. Comparing patients before (T0) and after (T1) switching, we found no statistically significant differences in terms of seizure frequency and occurrence of adverse effects. There were no significant differences (number of seizures/month and drug‐related adverse events) between patients treated with Matever® as monotherapy and patients who refused the switch and continued to use Keppra® as monotherapy for a long‐term follow‐up of 48 months. Electroencephalography findings were also unchanged.
Conclusion
In our sample, brand‐to‐generic levetiracetam switching was effective and safe in both monotherapy and polytherapy regardless of the epilepsy syndrome.
