Rapid progression to end-stage renal disease in a child with IgA-dominant infection-related glomerulonephritis associated with parvovirus B19

In this study, we report the case of a previously healthy 5-year-old boy with infection-related glomerulonephritis (IRGN) associated with PVB19 that progressed to end-stage renal disease (ESRD). He presented with macrohematuria, nephrotic-range proteinuria, and progressive renal dysfunction despite treatment with methylprednisolone pulse therapy, plasmapheresis, and intravenous immunoglobulin. The kidney biopsy specimens exhibited endocapillary infiltration and mesangiolysis with cellular crescent formation. Immunofluorescence analysis revealed that IgA was dominantly positive in the glomeruli, with some co-localized with KM55, which is a specific monoclonal antibody for galactose-deficient IgA1 (Gd-IgA1). The intensity of the KM55 signal in the present patient was weaker than that in patients with IgA nephropathy. To our knowledge, this is the first report of IRGN associated with PVB19 that progressed to ESRD without any underlying diseases. Further investigations are needed to determine the significance of IgA and Gd-IgA1 deposition in IRGN associated with PVB19.

We describe the most highly recommended generic and disease-specific PRO tools in SCD and discuss the challenges of incorporating them in clinical practice. EXPERT OPINION: PRO measures are essential to incorporate into SCD clinical trials either as primary or secondary outcomes. The use of PRO measures in SCD facilitates a patient-centered approach, which is likely to lead to improved outcomes. Significant challenges remain in adapting PRO tools to routine clinical use and in developing countries. PMID: 33034214 [PubMed - as supplied by publisher]

Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...

Authors: Mosquera J, Pedreañez A Abstract Increasing evidence supports a central role of the immune system in acute post streptococcal glomerulonephritis (APSGN), but the current view of how streptococcal biology affects immunity, and vice versa, remains to be clarified. Renal glomerular immune complex deposition is critical in the initiation of APSGN; however, mechanisms previous to immune complex formation could modulate the initiation and the progression of the disease. Initial and late renal events involved in the nephritis can also be related to host factors and streptococcal factors. In this review we ...

CONCLUSIONS: More than half of the iIONP patients had an enhanced oculomotor nerve in MRI. A few of them also had elevated CSF IgG synthesis rate, but no further evidence for inflammation was found. The administration of steroids seemed to have no benefit other than increasing the blood glucose level. PMID: 33029972 [PubMed]

Authors: Fentie K, Wakayo T, Gizaw G Abstract Background: Anemia defined as a low blood hemoglobin concentration is public health importance. The adolescence age group is the most neglected in public health and nutrition research as priorities are usually given to pregnant women, lactating mothers, and their children less than 2 years. Current Ethiopian Food and Nutrition policy included adolescent girls in the most at-risk group for nutritional demands; however, only a few published studies have assessed a deficiency of anemia and associated factors to tackle the intergenerational cycle of malnutrition.

AIM: To evaluate the real-world safety and efficacy of sofosbuvir plus ribavirin for elderly patients (≥ 75-years-old) compared to nonelderly patients, we conducted a post-marketing prospective cohort study. METHODS: We treated 265 patients with ge...

We report the rare case of a patient co-existing NS and DLBCL. DLBCL might be pathogenesis of NS; the findings are supported by the presence of MN, an underlying malignancy (DLBCL), and the lack of anti-PLA2R antibodies. Although further investigation is warranted, our case suggests that DLBCL is a possible cause of secondary MN. PMID: 33028760 [PubMed - in process]
