The most common founder pathogenic variant c.868G > A (p.Val290Met) in the gene in a representative adult Czech cohort with focal segmental glomerulosclerosis is associated with a milder disease and its underdiagnosis in childhood.

Background: Genetic focal segmental glomerulosclerosis (FSGS) is caused by pathogenic variants in a broad spectrum of genes that have a variable representation based on subjects' ethnicity and/or age. The most frequently mutated autosomal recessive gene in FSGS is . In this study, we analyzed the spectrum of variants and their associated phenotype in Czech adult FSGS patients.

Unveiling the Unexpected: Why Doctors Should Look beyond the Lungs when Predicting COVID-19 Mortality.

Introduction: The main objective of this study was to identify the best combination of admission day parameters for predicting COVID-19 mortality in hospitalized patients. Furthermore, we sought to compare the predictive capacity of pulmonary parameters to that of renal parameters for mortality from COVID-19.

Methods: In this retrospective study, all patients admitted to a tertiary hospital between September 1st, 2020, and December 31st, 2020, who were clinically symptomatic and tested positive for COVID-19, were included.

[Glomerulonephritides associated with infections].

Glomerulonephritides associated with infections constitute an important group of diseases. Their occurrence is shifting from children and young people to elderly people. The rates of acute post-streptococcal glomerulonephritis, a condition with a good prognosis, are decreasing, and the rates of glomerulonephritides associated with various bacterial, viral, or parasitic infections, often with a poor prognosis, are increasing.

Can Renal Parameters Predict the Mortality of Hospitalized COVID-19 Patients?

Introduction: Our study aimed to analyze whether renal parameters can predict mortality from COVID-19 disease in hospitalized patients.

Methods: This retrospective cohort includes all adult patients with confirmed COVID-19 disease who were consecutively admitted to the tertiary hospital during the 4-month period (September 1 to December 31, 2020). We analyzed their basic laboratory values, urinalysis, comorbidities, length of hospitalization, and survival.

Bioptically Proven "Anticoagulation-Related Nephropathy" Induced by Dual Antiplatelet Therapy.

Anticoagulation-related nephropathy (ARN) is a significant and underdiagnosed complication in patients who receive anticoagulation therapy. It is characterized by acute kidney injury in the setting of excessive anticoagulation defined as an international normalized ratio > 3.0 in patients treated with warfarin.

[More safe anticoagulant treatment - use of idarucizumab (Praxbind®): case reports from RE-VERSE AD study and clinical practice].

RE-VERSE AD, a prospective multicentric cohort study, examined the effect of idarucizumab on 2 cohorts of patients anticoagulated with dabigatran - in cohort A in patients with uncontrollable or life threatening bleeding, in cohort B in patients who undergo acute surgery. Within the study patients were intravenously administered 5 g antidote divided into 2 doses per 2.5 g within 15 min to eliminate the anticoagulation effect of dabigatran.

Clinical case: idelalisib-induced immunoglobulin flare.

IgM flare is a transient, treatment-induced, increase of monoclonal IgM levels in lymphoplasmacytic lymphoma/Waldenström macroglobulinemia (LPL/WM) patients. Until recently this phenomenon was observed in patients treated with Cladribine and Rituximab. Here we report a case of a heavily pretreated chronic lymphocytic leukemia patient with an atypically high immunoglobulin production who developed clinically significant immunoglobulin flare following Idelalisib treatment.
