Abstract
Proliferative glomerulonephritis with monoclonal immunoglobulin (mIg) deposits (PGNMID) is a rare glomerular disease characterized by glomerular deposits of mIg. The pathogenesis of PGNMID without circulating mIg is poorly understood but a role for aberrant immune response to infection or another exogenous stimulus has been proposed. We describe a unique case of PGNMID that presented with multiple episodes of acute kidney injury, nephritic syndrome, and hypocomplementemia, associated with self-limited febrile illnesses or COVID-19 vaccination. Monoclonal IgG lambda was detected in the serum and urine, consistent with monoclonal gammopathy of renal significance (MGRS). Consecutive kidney biopsies demonstrated evolving morphologic and immunohistologic features, with monotypic IgG lambda deposits identified only in the third biopsy. Despite the need for dialysis, renal dysfunction and hypocomplementemia resolved after each episode with corticosteroid therapy. This case illustrates infections or COVID vaccination maybe “second hits” that promote mIg deposition in PGNMID, possibly due to cytokine release by innate immune cells that promote endothelial cell injury.

Intrinsic Kidney Pathology Following COVID-19 Infection in Children and Adolescents: A Systematic Review. CHILDREN (BASEL, SWITZERLAND) 2021; 9:children9010003. [PMID: 35053628 PMCID: PMC8774577 DOI: 10.3390/children9010003] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 12/19/2021] [Accepted: 12/20/2021] [Indexed: 12/27/2022]
Abstract
Introduction: COVID-19 infections resulting in pathological kidney manifestations have frequently been reported in adults since the onset of the global COVID-19 pandemic in December 2019. Gradually, there have been an increased number of COVID-19-associated intrinsic kidney pathologies in children and adolescents reported as well. The pathophysiological mechanisms between COVID-19 and the onset of kidney pathology are not fully known in children; it remains a challenge to distinguish between intrinsic kidney pathologies that were caused directly by COVID-19 viral invasion, and cases which occurred as a result of multisystem inflammatory syndrome due to the infection. This challenge is made more difficult in children, due to the ethical limitations of performing kidney biopsies to reach a biopsy-proven diagnosis. Although previous systematic reviews have summarized the various pathological kidney manifestations that have occurred in adults following acute COVID-19 infection, such reviews have not yet been published for children and adolescents. We describe the results of a systematic review for intrinsic kidney pathology following COVID-19 infection in children and adolescents. Methods: A systematic literature search of published data up until 31 October was completed through the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines. Research articles reporting new-onset or relapsed intrinsic kidney pathology in children or adolescents (≤18 years) following acute COVID-19 infection were included for qualitative review. COVID-19 infection status was defined by a positive result from a RT-PCR, or nuclear antibody testing. Only full-text articles published in the English language were selected for review. Results: Twenty-nine cases from fifteen articles were included in the qualitative synthesis of this systematic review. Nephrotic syndrome, as an umbrella condition, appeared as the most frequently observed presentation (20 cases) with disease remission noted in all cases with steroid treatment. Other cases included numerous glomerulonephritides, such as acute necrotizing glomerulonephritis, MPO vasculitis and collapsing glomerulopathy, and thrombotic microangiopathies, such as aHUS. For patients with transplanted kidneys, T-cell-mediated rejection and mild tubular interstitial infiltration were noted following testing positive for COVID-19. There were no mortalities reported in any of the included cases, although two patients remained dialysis dependent at hospital discharge. Conclusion: This systematic review highlights the various intrinsic pathological kidney manifestations in children and adolescents as a result of acute COVID-19 infection. The clinical timeline and presentation of these cases support the mechanistic hypothesis between COVID-19 infection and the onset of intrinsic kidney pathologies within this context. The progressive introduction of vaccination programs for children and adolescents may hopefully reduce the severity of COVID-19-associated illnesses, and pathological kidney manifestations in this population.

Abstract
Proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID) is included in the group of dysproteinaemias causing renal disease. Only a minority of cases are associated with a haematological malignancy. Two cases have been linked to acute parvovirus B19 infections. We report a 36-year-old African-American woman who presented with renal dysfunction, proteinuria, haematuria and a kidney biopsy reported as PGNMID with IgG3-kappa deposits. Her evaluation for a haematological malignancy was unrevealing. Her parvovirus IgM and IgG levels were positive. The patient was initially treated with an ACE inhibitor and spontaneously remitted with minimal proteinuria after 1 month. Repeat parvovirus B19 serologies 6 months later showed persistent IgG and DNA by PCR positivity but IgM negativity. Given the clinical scenario, we believe that her PGNMID was induced by acute parvovirus B19 infection, which appeared to resolve once her acute infection abated. In this report, we describe our latest understanding of PGNMID.

Abstract
In the study's early stage, the research group had established an evaluation index system for the rational drug use of primary nephrotic syndrome in children. To assess the feasibility of the established index system, we conducted this empirical study.The cross-sectional study was conducted by using the Hospital Information System to extract some general clinical data of hospitalized children with primary nephrotic syndrome, which included registration number, age, sex, diagnosis and medication, etc. Utilize the SPSS23.0 software and Excel 2016 to descriptively analyze information.224 hospitalized children with primary nephrotic syndrome who met the inclusion criteria were included, ranging from 18 years old and 10 months to 11 months and 23 days, with an average age of 8.40, plus or minus 4.30 years. 148 males (66.07%) and 76 females (33.93%). The duration of hospitalization was 1-57 days, with an average hospitalization time of 10.59 days. The most common is respiratory infections, such as the bronchopneumonia, the mycoplasma pneumonia, etc. This study had successfully completed the measurement of the evaluation index system for the rational drug use of primary nephrotic syndrome in children.All indicators are feasible, but the operability and applicability need further research and improvement.

Abstract
Human parvovirus B19 infection causes a variety of glomerular diseases such as post-infectious acute glomerulonephritis and collapsing glomerulopathy. Although each of these appears independently, it has not been fully determined why parvovirus B19 provokes such a variety of different glomerular phenotypes. Here, we report a 68-year-old Japanese man who showed endocapillary proliferative glomerulonephritis admixed with podocytopathy in association with parvovirus B19 infection. The patient showed acute onset of heavy proteinuria, microscopic hematuria and kidney dysfunction with arthralgia and oliguria after close contact with a person suffering from erythema infectiosum. In the kidney biopsy specimen, glomeruli revealed diffuse and global endocapillary infiltration of inflammatory cells, with some also showing tuft collapse with aberrant vacuolation, swelling, and hyperplasia of glomerular epithelial cells. Immunofluorescence revealed dense granular C3 deposition that resembled the "starry sky pattern". Intravenous glucocorticoid pulse therapy followed by oral prednisolone and cyclosporine combination therapy resulted in considerable amelioration of the kidney dysfunction and urinary abnormalities. The present case reveals that parvovirus B19 infection can induce different glomerular phenotypes even in the same kidney structure. This finding may provide hints useful for the further elucidation of the pathogenesis of parvovirus B19-induced glomerular lesions.

Abstract
BACKGROUND Parvovirus B19 is a small, non-enveloped, single-stranded DNA virus with a special affinity for the erythroid progenitor cells of the bone marrow. The first case of parvovirus B19 infection in a kidney transplant recipient (KTR) was reported in 1986. Data on the risk factors and specific clinical characteristics of parvovirus B19 infection remain insufficient. METHODS We screened 602 KTRs for parvovirus B19 infection using parvovirus B19 polymerase chain reaction (PCR) from January 1990 to April 2016, and the clinical characteristics of patients with positive results were compared to those of age- and gender-matched patients with negative PCR results. RESULTS A total of 39 KTRs tested positive for parvovirus B19, and they were compared to 78 age- and gender-matched patients among 563 KTRs who had negative PCR results. In all, 89.7% of positive cases were reported within the first year after kidney transplantation. In multivariate analyses, deceased-donor kidney transplantation (odds ratio [OR] 9.067, 95% confidence interval [CI] 1.668-49.275, P = .011), use of tacrolimus (OR 3.607, 95% CI 1.024-12.706, P = .046), PCR test within 1 year of kidney transplantation (OR 12.456, 95% CI 2.674-58.036, P = .001), and hemoglobin levels (OR 0.559, 95% CI 0.351-0.889, P = .014) showed significant correlations with parvovirus B19 infection. Graft survival did not differ between the two groups during the follow-up period of 111.68 ± 54.54 months (P = .685 by log-rank test). CONCLUSION The identification of factors related to positive parvovirus B19 PCR results may promote the early detection of parvovirus B19 infection. Further studies are needed to elucidate the characteristics of parvovirus B19 infection in kidney transplantation.

Abstract
AIMS/INTRODUCTION To compare the incidence rate of renal dysfunction between patients with fulminant type 1 diabetes and those with acute-onset type 1 diabetes. MATERIALS AND METHODS The present retrospective cohort study included patients with fulminant type 1 diabetes and acute-onset type 1 diabetes diagnosed during April 1993 to March 2016 at a national center in Japan. Glycated hemoglobin levels, incidence rates of renal dysfunction defined as an estimated glomerular filtration rate of <60 mL/min/1.73 m2 and microalbuminuria were examined. RESULTS In total, 115 patients with type 1 diabetes (10 with fulminant type 1 diabetes and 105 with acute-onset type 1 diabetes) were included. The median glycated hemoglobin levels were significantly lower in patients with fulminant type 1 diabetes than in those with acute-onset type 1 diabetes 0, 3, 6 and 9 years after diabetes onset (6.5 vs 12.7%, 6.5 vs 7.9%, 6.7 vs 8.2%, 7.5 vs 8.5%, respectively). Kaplan-Meier analysis showed a significantly higher incidence rate of renal dysfunction in patients with fulminant type 1 diabetes than in those with acute-onset type 1 diabetes (hazard ratio 1.72, 95% confidence interval 1.01-2.97, P = 0.037). The incidence rate of microalbuminuria did not significantly differ between the groups (hazard ratio 0.97, 95% confidence interval 0.34-2.77, P = 0.95). Sensitivity analysis using age- and sex-matched patients with fulminant type 1 diabetes and acute-onset type 1 diabetes yielded similar results. CONCLUSIONS The risk of developing renal dysfunction is higher in patients with fulminant type 1 diabetes than in those with acute-onset type 1 diabetes, despite better glycemic control.

Abstract
Parvovirus B19 (B19V) and human bocavirus 1 (HBoV1), members of the large Parvoviridae family, are human pathogens responsible for a variety of diseases. For B19V in particular, host features determine disease manifestations. These viruses are prevalent worldwide and are culturable in vitro, and serological and molecular assays are available but require careful interpretation of results. Additional human parvoviruses, including HBoV2 to -4, human parvovirus 4 (PARV4), and human bufavirus (BuV) are also reviewed. The full spectrum of parvovirus disease in humans has yet to be established. Candidate recombinant B19V vaccines have been developed but may not be commercially feasible. We review relevant features of the molecular and cellular biology of these viruses, and the human immune response that they elicit, which have allowed a deep understanding of pathophysiology.

Abstract
Nephrotic syndrome without hematuria due to infection-related glomerulonephritis is uncommon. The present report describes a case of nephrotic syndrome due to infection-related glomerulonephritis without hematuria and hypertension in an older child. A 14-year-old boy was referred to our hospital because of a 5-day history of fever, nausea, weight gain and recent leg edema without hypertension. Laboratory data showed nephrotic-range proteinuria, hypoalbuminemia, mild hypocomplementemia and acute renal injury without hematuria. Although, due to the clinical presentation, minimal-change nephrotic syndrome was mostly suspected, a renal biopsy showed endocapillary hypercellularity mainly of mononuclear cells with segmental mesangiolytic changes. Fine granular IgG and C3 deposits were noted by an immunofluorescent study; many relatively small electron-dense deposits were observed electron-microscopically. These findings led to the diagnosis of nephrotic syndrome due to infection-related endocapillary proliferative glomerulonephritis, although the causative organism of his nephritis was not detected. He recovered with rest and dietary cure. When we examine an acute nephrotic child, infection-related glomerulonephritis should be considered as the differential diagnosis to avoid unnecessary use of corticosteroids.

Abstract
OBJECTIVE We investigated the incidence of human parvovirus B19 (HPV B19) infection after renal transplantation as well as the risk of anemia and renal allograft damage among infected transplant recipients in China. METHODS We selected 114 patients at 1-18 months after renal transplantation for detection of HPV B19 DNA copies compared with a control population. Renal function and hematopoiesis were compared between infected and noninfected groups. RESULTS Twenty-seven patients diagnosed with HPV B19 infection during follow-up (18.75%),which was a significantly higher number than among the general population over the same period. Infected versus nonaffected patients exhibited a significantly higher incidence of anemia and urinary abnormalities in addition to significantly lower values of hemoglobin, higher serum creatinine concentrations, and lower glomerular filtration rates. The 2 groups did not differ in the types or doses of calcineurin inhibitor (CNI) immunosuppressants. Two cases of pure red cell aplasia (PRCA) as confirmed using bone marrow biopsy, were observed in the infected group. They displayed HPV B19 DNA copy numbers >10(7)/mL and segmental mesangial cell proliferation on renal biopsy. The PRCA cases were cured with immunomodulatory therapy. CONCLUSIONS The HPV B19 infection rate was significantly higher among renal transplant recipients than normal controls. Infections correlated with damage to the renal allograft, which may in turn cause PRCA. Immunomodulation therapy was effective to treat this complication of HPV B19 infection.

Abstract
BACKGROUND Renal manifestations are rare in Kawasaki disease (KD). Acute renal failure with tubular necrosis, tubulointerstitial nephritis and renovascular hypertension have been reported in KD, but only one case of a patient with KD associated with nephrotic syndrome (NS) has been reported to date, with the patient improving on steroid therapy but dying from coronary aneurysm. METHODS We report the cases of three children, aged 4, 4.5 and 8 years, respectively, who presented with typical KD symptoms (high fever, diffuse maculopapular rash, conjunctivitis, peripheral oedema, cervical adenopathies and high C reactive protein levels) and developed NS. RESULTS Patient 1 had a haemodynamic shock due to cardiac dysfunction and transient renal failure. Ten days later, he developed a NS which spontaneously disappeared 1 week later. Patient 2 had a NS on admission with normal plasma creatinine and no haematuria. Proteinuria disappeared within 10 days. Patient 3 developed NS 5 days after onset with a moderate increase in plasma creatinine. Proteinuria disappeared within 2 weeks. All three patients were treated with intravenous immunoglobulins, antibiotic therapy and aspirin, but none of them received steroid therapy. To date, all three patients have maintained long-term remission. CONCLUSIONS In conclusion, proteinuria with NS may develop during the acute phase of KD with persistent remission occurring without steroid therapy.

Abstract
BACKGROUND Collapsing glomerulopathy may occur in an idiopathic (primary) form and in association with a wide spectrum of infectious and inflammatory conditions and medications. The association of collapsing glomerulopathy with human immunodeficiency virus (HIV)-1 infection is well established; less certain is the association with other viral infections. METHODS We searched PubMed for articles in all languages that addressed glomerulopathies associated with parvovirus B19, cytomegalovirus (CMV), Epstein-Barr virus (EBV), hepatitis C virus (HCV) and simian virus 40 (SV40). RESULTS Case reports and small-case series link infection with these common viruses and glomerular injury. The evidence for a pathogenic role is generally stronger for glomerulonephritis than for collapsing glomerulopathy. CONCLUSIONS The evidence linking collapsing glomerulopathy with CMV is relatively strong but not yet conclusive, while the evidence for a pathogenic role for EBV and parvovirus B19 is weaker.

Abstract
The prevalence of postinfectious glomerulonephritis has decreased in most developed countries. We report the case of a previously healthy, immunocompetent 65-year-old woman who developed acute glomerulonephritis associated with human parvovirus B19 infection. She was referred by her primary care physician for suspected congestive heart failure but she had an elevated creatinine level and an abnormal urinalysis. Renal biopsy showed diffuse endocapillary proliferative glomerulonephritis. After biopsy, we learned that she had been in frequent contact with her grandson who had been diagnosed with erythema infectiosum. Her human parvovirus B19 serum IgM titer was elevated at 3.50, indicating current infection.

Abstract
Immunoglobulin A nephropathy (IgAN) is one of the most common causes of chronic glomerulonephritis (CGN) in the world. The proliferative and crescentic forms of IgA are found in up to 30% of cases and are associated with nephritic-range proteinuria, accelerated hypertension, and accelerated decline toward end-stage renal disease. On the other hand, Henoch-Schönlein purpura (HSP) is a systemic disorder characterized by leukocytoclastic vasculitis involving the capillaries and the deposition of IgA immune complexes. Renal involvement is the principal cause of morbidity and mortality in children with HSP. Two entity diseases are important as renal diseases in childhood. We herein review the mechanism of the onset and exacerbation of IgAN and HSP nephritis (HSPN) and its treatment. As to the pathogenesis, we found that CB4 provoked exacerbation of renal pathologic findings in hyper IgA mice via endothelial injury, γ-interferon production, and dysfunction of the mesangial pathway and could possibly become one of the factors involved in the mechanism of the onset or evolution of human IgAN. As to the treatment of IgAN and HSPN, we evaluated the efficacy of multidrug combination therapy (prednisolone, warfarin, and dipyridamole, including mizoribine) for diffuse IgAN and the efficacy of methylprednisolone and urokinase pulse therapy plus immunosuppressive drugs for severe HSPN in children. These therapies were effective in ameliorating the proteinuria and histologic severity of patients with IgAN or HSPN. In future, detailed investigations into the pathogenesis of CGN and double-blind randomized control studies on children with IgAN or HSPN will be necessary.

Abstract
Collapsing glomerulopathy is a proliferative disease defined by segmental or global wrinkling of the glomerular basement membranes associated with podocyte proliferation. These lesions are particularly poor responders to standard therapies. First described as an idiopathic disorder or following HIV infection, it is now associated with a broad group of diseases and different pathogenetic mechanisms, which participate in podocyte injury and mitogenic stimulation. Because of this etiologic heterogeneity, there is clear need for new therapeutic approaches to target each variant of this entity. Historical background, terminology, morphologic and phenotypic features, and suggested mechanisms are reviewed in this manuscript.

Abstract
Parvovirus B19 is a common human pathogen, causing erythema infectiosum in children, hydrops fetalis in pregnant women, and transient aplastic crisis in patients with chronic hemolytic anemia. Immunosuppressed patients can fail to mount an effective immune response to B19, resulting in prolonged or persistent viremia. Renal transplant recipients can develop symptomatic B19 infections as a result of primary infection acquired via the usual respiratory route or via the transplanted organ, or because of reactivation of latent or persistent viral infection. The most common manifestations of B19 infection in immunosuppressed patients are pure red cell aplasia and other cytopenias. Thus, this diagnosis should be considered in transplant recipients with unexplained anemia and reticulocytopenia or pancytopenia. Collapsing glomerulopathy and thrombotic microangiopathy have been reported in association with B19 infection in renal transplant recipients, but a causal relationship has not been definitively established. Prompt diagnosis of B19 infection in the renal transplant recipient requires a high index of suspicion and careful selection of diagnostic tests, which include serologies and polymerase chain reaction. Most patients benefit from intravenous immunoglobulin therapy and/or alteration or reduction of immunosuppressive therapy. Conservative therapy might be sufficient in some cases.

Abstract
Infection with parvovirus B19 causes several clinical syndromes (fifth disease, transient aplastic crisis, pure red cell aplasia, and hydrops fetalis) and may contribute to other illnesses. B19 has been linked to renal disease in three settings: As a cause of acute glomerulopathy and as a cause of anemia in ESRD and kidney transplantation. Case reports implicate parvovirus in the pathogenesis of proliferative glomerulonephritis and collapsing glomerulopathy, but a causal relationship has not been established. A proposed role for B19 infection is based on the temporal association of renal findings with viral infection, positive serology, and identification of the viral genome in the glomerulus. Mechanisms may include cytopathic effects on glomerular epithelial cells and/or endothelial cells and glomerular deposition of immune complexes. Patients who require dialysis may have increased susceptibility to acute and chronic anemia after parvoviral infection. Factors that predispose this population to complications of B19 infection include impaired immune response, deficient erythropoietin production, and possibly decreased erythrocyte survival. The clinical burden of parvovirus B19 infection in renal transplant recipients may be underestimated; these individuals may develop persistent viremia as a result of a dysfunctional immune response. Chronic anemia and pure red blood cell aplasia are the most common complications of parvovirus infection in this population; the diagnosis should be considered in transplant recipients with unexplained anemia or pancytopenia. Allograft rejection and dysfunction have been reported in association with infection, but a cause-effect relationship has not been proved. Further investigation of the relationship between B19 and kidney disease is warranted.

Abstract
For clarification of the pathogenetic role of viral infection in chronic glomerulonephritis, the renal effects of Coxsackie B4 virus (CB4) were examined in hyper-IgA (HIGA) mice. In experiment 1, HIGA mice (n = 75) were inoculated intravenously with live CB4 and inactivated CB4 once a month from 1 to 12 mo of age. In experiment 2, HIGA mice (n = 45) were inoculated intravenously with live CB4 and inactivated CB4 once at 6 wk of age. In experiment 3, 60 mice were inoculated intravenously with carbon and live or inactivated CB4 once at 6 wk of age. Mice in the control group were inoculated with vehicle. The kidneys were extirpated from five mice of each group killed with time after inoculation for histologic evaluation. The scores for mesangial IgA deposition, PCNA-positive cells, and matrix at 20 wk were higher in mice with live CB4 than in mice with inactivated CB4 or without CB4. On electron microscopic examination, swelling and detachment of endothelial cells from 24 h after inoculation and increase of serum IFN-gamma concentration were found in mice with live CB4. Many carbon particles were present in peripheral and central zones of the mesangium from 5 to 10 d in mice with carbon and live CB4. These results suggest that CB4 provokes exacerbation of renal pathologic findings in HIGA mice via endothelial injury, IFN-gamma production, and dysfunction of the mesangial pathway.
