We have read with great interest the paper of He et al. published in April 2020 about haematological patients infected with SARS-COV-2 [1]. Although it was a small series with 13 patients, it gave a good insight into the course and outcome of the infection in this patient category. Interestingly, limited data about SARS-COV-2 in haematological patients have become available since this report, with just two other cohorts published [2, 3]. Because of the high mortality in this vulnerable group of patients, it is important to have more information about the course and outcome of this disease in larger patient series. We describe in this letter a cohort of 59 COVID-19 patients with an underlying haematological disease from three European countries. This retrospective case study was performed in four hospitals across Europe: Spain (Hospital Ramón y Cajal, Madrid), Northern-Italy (ASST, Crema, and San Giovanni Bosco General Hospital, Turin) and the Netherlands (University Medical Center Groningen). Patients with COVID-19 infection and a concomitant haematological disease were identified between 10 February 2020 and 15 May 2020. COVID-19 diagnosis was confirmed * Jaap van Doesum j.a.
We report a case of massive cerebral venous sinus thrombosis in the contest of vaccine-induced immune thrombotic thrombocytopenia that required the rapid coordination of many specialists from different departments, notably emergency, neurology, neuroradiology, hematology, and neurosurgery. The patient was rapidly treated with steroids, immunoglobulin, and fondaparinux. She underwent within 6 h after hospital admission a mechanical thrombectomy in order to allow flow restoration in cerebral venous systems. Neuroendovascular treatment in cerebral venous thrombosis related to VITT has never been described before. It can represent a complementary tool along with the other therapies and a multidisciplinary approach.
Monoclonal Gammopathy of Renal Significance (MGRS) is a group of heterogeneous disorders characterized by renal dysfunction secondary to the production of a monoclonal immunoglobulin by a nonmalignant B cell or plasma cell clone. We report the clinical and histological outcomes of two patients with biopsy-proven MGRS: one patient showed membranoproliferative glomerulonephritis with monoclonal k-light chain and C3 deposits, the second patient showed immunotactoid glomerulopathy. Both patients were treated with a 9-month chemotherapy protocol including bortezomib, cyclophosphamide, and dexamethasone. Renal biospy was repeated after 1 year. The estimated glomerular filtration rate (eGFR) increased from 22.5 (baseline) to 40 ml/min per 1.73 m2 after 12 months, then to 51.5 ml/min per 1.73 m2 after 24 months; proteinuria decreased from 4.85 (baseline) to 0.17 g/day after 12 months, then to 0.14 g/day after 24 months. Repeat renal biopsies showed a dramatic improvement of the glomerular proliferative lesions and near complete disappearance of the immune deposits. A bortezomib-based treatment proved very effective and was well-tolerated in the two patients presenting with clinically and histologically aggressive MGRS.
Background: Ischemic stroke is rare in young adults, with an incidence of about 10-15% of all the ischemic strokes. In about one third of these patients a cause is missing. Among patients with antiphospholipid antibodies syndrome (APS), stroke is the first thrombotic event in about 13% of cases. Aims of our project were: to evaluate the prevalence of antiphosfolipid antibodies (aPL),to investigate on the prevalence of conventional risk factors and to define the radiological characteristics of the ischemic lesion. Materials and methods: this is a no profit, observational multicenter prospective study. Inclusion criteria were: age older than 18 and younger than 55 years, informed written consent, a clinical and radiological diagnosis of stroke. Patient's data were collected at diagnosis and after 30 days from stroke. If any aPL positivity was found the patient was referred to our service to further/eventually confirm the diagnosis of APS. For each patient these data were collected: age, sex, body mass index, personal and familial history, concomitant co morbidities and therapies, cardiovascular risk factors, drug abuse. CT scan or angioCT or MRI was always performed at diagnosis, aPL profile was determined at diagnosis and eventually confirmed after 12 weeks according to the Sapporo criteria. None of the patients had a previous diagnosis of APS. Results: enrolled patients from January 2017 to December2018 were 46 out of 425 ischemic stroke (10.8%). We found 11/46 aPL positivity patients. Among these patients, 7 were confirmed at 12 weeks (15%). Baselines characteristics of the study population are detailed in table 1. We found a high prevalence of associated conventional cardiovascular risk factors: hypertension (56%), dyslipidemia ( 50%), obesity (55%), smoke ( 52%). We didn't find any correlation between APS and a clear radiological pattern on MRI and CT scan. Conclusions: Prevalence of APS was 15% in our cohort of young patients with stroke, 85% of which had an high risk aPL profile. The detection frequency is similar to the recent APS-ACTION and literature findings. In our cohort stroke was a relapse of a previous ischemic event in 24% of the patients, while in 15% there was a stroke's relapse. Even if these data should be confirmed with a wider number of patients, it seems to be useful to evaluate the presence of aPL in a young patient with ischemic stroke .

We present the case of a woman developing nephrogenic diabetes insipidus in the course of stage IVB T lymphoma with no involvement of the hypothalamus/pituitary area, but extensive involvement of both kidneys. A diagnosis of tubulopathy with acquired nephrogenic diabetes insipidus was made.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
