RESUMO

BACKGROUND: The present study focuses on the associations of streptococcal infection with the clinical phenotypes, relapse/recurrence and renal involvement in Henoch-Schönlein purpura (HSP) children. METHODS: Two thousand seventy-four Chinese children with HSP were recruited from January 2015 to December 2019. Patients' histories associated with HSP onset were obtained by interviews and questionnaires. Laboratory data of urine tests, blood sample and infectious agents were collected. Renal biopsy was performed by the percutaneous technique. RESULTS: (1) Streptococcal infection was identified in 393 (18.9%) HSP patients, and served as the most frequent infectious trigger. (2) Among the 393 cases with streptococcal infection, 43.0% of them had arthritis/arthralgia, 32.1% had abdominal pain and 29.3% had renal involvement. (3) 26.1% of HSP patients relapsed or recurred more than 1 time within a 5-year observational period, and the relapse/recurrence rate in streptococcal infectious group was subjected to a 0.4-fold decrease as compared with the non-infectious group. (4) No significant differences in renal pathological damage were identified among the streptococcal infectious group, the other infectious group and the non-infectious group. CONCLUSIONS: Streptococcal infection is the most frequent trigger for childhood HSP and does not aggravate renal pathological damage; the possible elimination of streptococcal infection helps relieve the relapse/recurrence of HSP.

RESUMO

RESUMEN La vasculitis IgA, también conocida como púrpura de Schönlein-Henoch, es una vasculitis leucocitoclástica que involucra pequeños vasos con depósito de inmunocomplejos IgA. Puede abarcar piel, articulaciones, riñones y tracto gastrointestinal. Su presentación en adultos es rara, y las formas clínicas suelen ser más agresivas. Es objetivo del presente trabajo describir el curso y evolución de vasculitis IgA, en un paciente de 59 años, con púrpuras en miembros inferiores y tronco, hematuria macroscópica, y edema de miembros inferiores. Los complementarios mostraron creatininas elevadas, proteinuria de rango nefrótico, elevación de la IgA y anticuerpos contra el citoplasma de los neutrófilos negativos. Se descartaron causas neoplásicas. El estudio anatomo-patológico del riñón concluyó una vasculitis IgA.


ABSTRACT IgA vasculitis, also known as Henoch-Schönlein purpura, is a leukocytoclastic vasculitis that involves small vessels with deposition of IgA immune complexes. It can include skin, joints, kidneys, and gastrointestinal tract. Its presentation in adults is rare, and the clinical forms are usually more aggressive. The objective of this study is to describe the course and evolution of IgA vasculitis, in a 59-years-old patient, with purples in the lower limbs and trunk, macroscopic hematuria, and lower limb edema. The complementary ones showed elevated creatinines, nephrotic range proteinuria, elevated IgA and negative antibodies against the cytoplasm of neutrophils. Neoplastic causes were dismissed. The anatomical-pathological study of the kidney concluded IgA vasculitis.

RESUMO

BACKGROUND: Henoch-Schönlein purpura (HSP) is the most common vasculitis of childhood. It has a characteristic rash described as palpable purpura that most frequently affects the distal lower extremities and buttocks. HSP rarely presents with bullous rash nor pulmonary nodules. CASE PRESENTATION: We present a novel case of a 12-years-old female with recurrent pediatric HSP with a combination of the rare manifestations of bullous rash and pulmonary nodules. She initially presented with the bullous rash, chest pain, cough, and abdominal pain. Patient was successfully treated with intravenous pulse corticosteroids followed by a high dose oral corticosteroid taper, with resolution of the bullous rash and pulmonary nodules. CONCLUSION: The rare manifestations of scarring bullous rash and pulmonary nodules can be presenting features of pediatric HSP, the combination of which has not been previously reported. The treatment of intravenous corticosteroid resolved patient's abdominal symptoms, rash and pulmonary nodules.

RESUMO

Tumour necrosis factor-α [TNF-α] inhibitors have revolutionised the management of chronic inflammatory conditions. A number of cutaneous adverse events have been reported with TNF inhibition, including vasculitis. Most reactions are mild and rarely warrant treatment withdrawal. Here we describe a patient with Crohn's disease treated with adalimumab in whom severe multivisceral Henoch-Schönlein purpura developed, including neurological involvement, requiring definitive TNF blocker withdrawal.

RESUMO

OBJECTIVE: To identify risk factors associated with unfavorable outcomes in children with IgA vasculitis with nephritis (Henoch-Schonlein purpura nephritis)(IgA-VN). METHODS: PubMed, Embase, and Web of Science databases were searched for studies, published in English through February 2019. The data were extracted to perform pooled analysis, heterogeneity testing, subgroup analysis, sensitivity analysis, and publication bias analysis. RESULTS: This meta-analysis showed that, older age at onset (WMD 1.77, 95% CI 0.35-3.18, p = 0.014), lower glomerular filtration rate (GFR; WMD -23.93, 95% CI -33.78- -14.09, p<0.0001), initial renal manifestations with nephrotic syndrome (OR 1.74, 95% CI 1.12-2.70, p = 0.013), with nephritic-nephrotic syndrome (OR 4.55, 95% CI 2.89-7.15, p<0.0001) and renal biopsy with crescentic nephritis (International Study of Kidney Disease in Children [ISKDC] grades III-V) (OR 3.85, 95% CI 2.37-6.28, p<0.0001) were significant risk factors associated with poor outcomes in IgA-VN, whereas initial clinical features with hematuria (OR 0.33, 95% CI 0.16-0.69, p = 0.003) and mild proteinuria±hematuria (OR 0.46, 95% CI 0.28-0.75, p<0.0001) were associated with progression to good outcomes. By contrast, gender, hypertension and initial renal manifestations of acute nephritic syndrome were not significantly associated with poor outcomes in IgA-VN. CONCLUSION: This meta-analysis showed that older age at onset, lower GFR, initial renal features of nephrotic syndrome and nephritic-nephrotic syndrome and renal biopsy with crescentic nephritis (ISKDC grades III-V) were predictive of poor prognosis in children with IgA-VN.

RESUMO

Abstract Background: The Henoch-Schonlein Purpura (HSP) or IgA vasculitis is the most common vasculitis of childhood and may occur with renal involvement, with hematuria and / or proteinuria, and may cause severe and non-reversible sequelae. Objectives: To establish the profile of patients with renal involvement due to IgA vasculitisand to describe our experience with the use of azathioprine to treat patients with nephritis. Methods: Clinical data were retrospectively collected from medical records of patients with IgA vasculitiswho attended the pediatric rheumatology unit between 1995 and 2017. Patients were separated into two groups based on whether or notthey weretreated with non-glucocorticoid immunosuppressants. Results: From the178 patients with IgA vasculitis, nephritis was found in67 patients (37.6%), 13 of whom receivedtreatment with non-glucocorticoid immunosuppressants. Ten patients responded well to azathioprine and 1 patient to cyclosporine. Forty patients received oral glucocorticoids, whilst 16received intravenous glucocorticoids. Conclusion: Azathioprine may be beneficial in the treatment of IgA vasculitis with renal involvement.

RESUMO

BACKGROUND: In glomerular injury dendrin translocates from the slit diaphragm to the podocyte nucleus, inducing apoptosis. We analyzed dendrin expression in IgA glomerulonephritis and Henoch Schönlein purpura (IgAN/HSP) versus in podocytopathies minimal change disease (MCD) and focal segmental glomerulosclerosis (FSGS), and compared it to pathohistological findings and renal function at the time of biopsy and the last follow-up. METHODS: Twenty males and 13 females with median of age 35 years (min-max: 3-76) who underwent percutaneous renal biopsy and had diagnosis of glomerular disease (GD) were included in this retrospective study. Fifteen patients had IgAN/HSP and eighteen podocytopathy. Control group consisted of ten patients who underwent nephrectomy due to renal cancer. Dendrin expression pattern (membranous, dual, nuclear or negative), number of dendrin positive nuclei and proportion of dendrin negative glomeruli were analyzed. RESULTS: In GD and the control group significant differences in number of dendrin positive nuclei and proportion of dendrin negative glomeruli were found (P = 0.004 and P = 0.003, respectively). Number of dendrin positive nuclei was higher in podocytopathies than in IgAN/HSP, 3.90 versus 1.67 (P = 0.028). Proportion of dendrin negative glomeruli correlated to higher rates of interstitial fibrosis (P = 0.038), tubular atrophy (P = 0.011) and globally sclerotic glomeruli (P = 0.008). Dual and nuclear dendrin expression pattern were connected with lower rate of interstitial fibrosis and tubular atrophy than negative dendrin expression pattern (P = 0.024 and P = 0.017, respectively). Proportion of dendrin negative glomeruli correlated with lower creatinine clearance (CC) at the time of biopsy and the last follow-up (P = 0.010 and P < 0.001, respectively). Dendrin expression pattern correlated to CC at the last follow-up (P = 0.009), being lower in patients with negative than nuclear or dual dendrin expression (P = 0.034 and P = 0.004, respectively). CONCLUSION: In this pilot study the number of dendrin positive nuclei was higher in podocytopathies than in inflammatory GD. Negative dendrin expression pattern correlated to chronic tubulointerstitial changes and lower CC, which needs to be confirmed in a larger series.

RESUMO

The cause of Henoch-Schonlein purpura, or IgA vasculitis, is largely unknown. It has been associated with infections, other rheumatologic triggers, and adverse drug reactions. Rarely, adult Henoch-Schonlein purpura is also associated with solid-tumor malignancies. We present the case of a 66 year-old woman who presented with Henoch-Schonlein purpura associated with a metastatic malignancy of unknown primary origin. We recommend that adult patients presenting with Henoch-Schonlein purpura, especially those with no identifiable trigger, receive age-appropriate work-up for potential malignancy.

RESUMO

RATIONALE: Ulcerative colitis (UC) is one of the chronic inflammatory diseases of the intestinal tract. UC being misdiagnosed as Henoch-Schönlein purpura (HSP) in the elderly has seldom been reported about. PATIENT CONCERNS: A 64-year-old man was admitted to the hospital with petechiae and palpable purpura in lower limbs and abdominal pain for about 1 month. DIAGNOSES: Colonoscopy demonstrated severe inflammation in the colon, mucosal congestion, and edema, and multiple hemorrhages and ulcerations, with purulent adhesions. A histopathologic examination of the colon biopsies revealed extensive infiltration of immune cells and mucosal ulcerations in the intestine. UC was diagnosed. INTERVENTIONS: The patient was treated with prednisone (1.0 mg/kg/d) with progressive dose reduction. OUTCOMES: The skin lesions were healed within 4 weeks, and his abdominal pain was alleviated remarkably. He is currently under follow-up. LESSONS: As the treatment used for patients with HSP was not effective, it was advised that UC should be taken into consideration.

RESUMO

BACKGROUND: Henoch-Schönlein purpura nephritis (HSPN) is a form of small vessel vasculitis associated with purpura and IgA deposition in the glomeruli. The International Study of Kidney Disease in Children (ISKDC) classification predicts renal prognosis in children with HSPN, but not in adults. Additionally, it is not well known whether the Oxford classification 2016 and/or the Japanese Histologic classification (JHC) are associated with renal outcome. Herein, we investigated the relationship between pathological characteristics and renal outcome among adult patients with HSPN. METHODS: A multicenter retrospective cohort study was conducted in adult patients with HSPN who underwent renal biopsy between 2004 and 2014. Two nephrologists classified each patient according to the Oxford classification 2016, JHC, and the ISKDC classification. Renal outcome was defined by a 30% decline in the eGFR and/or end-stage kidney disease. RESULTS: We enrolled 74 adult patients with HSPN (mean age, 47.8 ± 17.4 years; mean eGFR, 76.4 ± 25.8 ml/min/1.73 m2; median proteinuria, 1.40 [IQR: 0.70-2.38] g/day). During a mean follow-up period of 68.0 ± 33.0 months, fourteen patients (18.9%) reached the renal outcome, and all 14 had received immunosuppressive therapy. The log-rank test revealed that event-free renal survival was significantly shorter in patients with endocapillary proliferation (E1) according to the Oxford classification than in those with E0 (p = 0.0072). However, the JHC, ISKDC classification and other Oxford lesions could not demonstrate a significant difference in event-free renal survival. In a multivariate Cox model adjusted for clinical and pathological factors, age (HR, 1.57; 95% CI, 1.12-2.21) and E lesion (HR, 6.71; 95% CI, 1.06-42.7) were independent risk factors for renal outcome. CONCLUSIONS: Endocapillary proliferation is significantly associated with renal outcome in adult patients with HSPN, including those receiving immunosuppressive therapy. Other Oxford classification lesions, JHC, and ISKDC classification were not associated with renal outcome.

RESUMO

Objetivo. Determinar la frecuencia de mutaciones del gen MEFV en niños con diagnóstico de púrpura de Schonlein-Henoch y evaluar el efecto que tienen en el pronóstico. Materiales y métodos. Estudio transversal que incluyeron pacientes pediátricos de entre 2 y 11 años, con diagnóstico de púrpura de Schonlein-Henoch. Se estudiaron para detectar 6 mutaciones en el gen MEFV (M694V, M680I, A744S, R202Q, K695R y E148Q). Resultados. Se incluyeron ochenta pacientes, de los cuales el 55% eran de sexo masculino (n= 44). La media de edad fue 6,44 ± 2,52 años. Durante el seguimiento, 9 pacientes presentaron recurrencia de la enfermedad, 5 sufrieron invaginación intestinal y 1 paciente tuvo convulsiones. Aproximadamente la mitad de los pacientes recibió corticoides. En 44 pacientes (55%) no se detectaron mutaciones en el gen MEFV. En 19 pacientes (22%) hubo una mutación heterocigota. Se encontró E148Q en 8 pacientes, M694V en 5 pacientes, A744S en 4 pacientes y la mutación heterocigota R202Q en 2 pacientes. En 1 paciente se detectó la mutación heterocigota M608I y en otro paciente se encontró la mutación homocigota M694V. En 15 pacientes se encontraron mutaciones heterocigotas compuestas en el gen MEFV. Las mutaciones en el gen MEFV no se correlacionaban con la frecuencia de compromiso renal y gastrointestinal ni con el pronóstico, desarrollo de complicaciones y uso de corticoides. Conclusiones. Las mutaciones en el gen MEFV no se correlacionan con la evolución clínica ni con las complicaciones en pacientes pediátricos con púrpura de Schonlein-Henoch en Turquía.


Objective. To determine the frequency of the MEFV gene mutations in pediatric patients diagnosed with HSP and to assess the effect of the MEFV gene mutations on their prognosis. Material and Methods. Ccross-sectional study; pediatric patients between 2-11 years diagnosed with HSP were included. These cases were investigated for 6 MEFV gene mutations (M694V, M680I, A744S, R202Q, K695R, E148Q). Results. Eighty cases were included in the study of which 55% were male (n= 44). The mean age was 6.44 ± 2.52 years. Disease recurrence occurred in 9 patients, invagination in 5 patients and convulsion in 1 patient during follow-up. Approximately half of the patients received steroids. The MEFV gene mutations was not detected in 44 (55%) of the patients. There was a heterozygous mutation in 19 (22%). E148Q was found in 8 patients, M694V in 5 patients, A744S in 4 patients, and the R202Q heterozygous mutation in 2 patients. The M608I homozygous mutation was detected in 1 patient and the M694V homozygous mutation in 1 patient. The compound heterozygous MEFV gene mutations was found in 15 patients. The presence of the MEFV gene mutations was not correlated with the frequency of renal and gastrointestinal involvement and prognosis, the development of complications and the use of steroids. Conclusion. The presence of the MEFV gene mutations does not correlate with the clinical course and complication in Turkish pediatric patients with HSP.

RESUMO

BACKGROUND: The clinical presentation and prognosis of adult and elderly patients with IgA vasculitis (Henoch-Schönlein purpura) accompanied by nephritis (IgAV-N) have not been investigated in detail. We therefore surveyed the features and outcomes of IgAV-N based on nationwide data derived from the Japan Renal Biopsy Registry (J-RBR). METHODS: This multi-center cohort study compared the clinicopathological parameters at diagnosis, initial therapies and outcomes between 106 adult (age 19-64 years) and 46 elderly (≥65 years) patients with IgAV-N who were registered in the J-RBR between 2007 and 2012. The primary end-points comprised a 50% increase in serum creatinine (sCr) values or end-stage kidney disease. Factors affecting a decrease in renal function were assessed using Cox proportional hazards models. RESULTS: Rates of hypertension, impaired renal function, hypoalbuminemia and crescentic glomerulonephritis were significantly higher among the elderly, than the adult patients. About 80% and 60% of the patients in both groups were respectively treated with corticosteroid and a renin-angiotensin system (RAS) blockade. Both groups had favorable renal survival rates for nine years (93.6% and 91.4% of the adult and elderly patients, respectively). Significantly more elderly than adult patients developed a 50% increase in sCr during a mean observation period of 3.9 years (21.7% vs. 4.7%, p = 0.012), and significantly fewer elderly, than adult patients achieved clinical remission (23.9% vs. 46.2%, p = 0.016). Multivariate analysis selected advanced age (≥65 years) and lower serum albumin values as independent prognostic factors for a decline in renal function, whereas steroid pulse therapy helped to preserve renal function. CONCLUSIONS: The renal prognosis of adult and elderly patients with IgAV-N was favorable when treated aggressively with corticosteroid and RAS blockade. However, the course of renal function should be carefully monitored in patients aged over 65 years and those with hypoalbuminemia.

RESUMO

Immunoglobulin A associated vasculitis (IgAV), formerly called Henoch-Schönlein purpura, is a small vessel vasculitis which typically presents with upper and lower extremity palpable purpura and abdominal pain. It is the most common vasculitis in children, and is less common in adults. However, newer evidence suggests the incidence within the adult population is higher than previously reported. This case study demonstrates an adult military recruit presenting with new onset IgAV shortly after basic training. He noted a preceding upper respiratory tract infection, which is a common finding in those presenting with IgAV. The diagnosis was made by clinical findings, histopathological results and direct immunofluorescence. Adults tend to develop more necrotic and bullous lesions when compared with children. This can skew histopathology and direct immunofluorescence. There is no clear consensus in current literature for whether to obtain lesional or perilesional biopsies. Such recommendations could be particularly advantageous for adults given the abnormal lesions. This case study addresses the incidence of IgAV within the adult population, diagnostic criteria, long-term sequalea of IgAV, and the importance of a proper biopsy sight when making the diagnosis.

RESUMO

A 60-year-old man with a history of hypertension, type 2 diabetes, and reflux esophagitis was admitted to our hospital with hemoptysis, dyspnea, and leg edema. We diagnosed him with adult IgA vasculitis based on the presence of purpura, elevated serum IgA fibronectin complexes, pathophysiological findings, a skin biopsy showing leukocytoclastic vasculitis, and immunofluorescence studies demonstrating granular IgA and C3 deposits in the blood vessel wall. He showed concurrent cardiopulmonary involvement without involvement of the gastrointestinal system and kidneys, which are commonly affected in IgA vasculitis patients. Following treatment with prednisolone, the patient recovered with improvement in cardiopulmonary manifestations.

RESUMO

We aimed to investigate the differences in renal histopathological changes and laboratory parameters between adult and pediatric patients with Henoch-Schönlein purpura nephritis (HSPN), and to analyze the correlation between laboratory parameters and renal histopathological grading. A total of 139 patients diagnosed with HSPN between September 2010 and December 2014 at the First Hospital of Jilin University, China, were retrospectively reviewed. The clinical and pathological characteristics were examined and compared between the adult and the pediatric patients. A majority of adult (75.0%) and pediatric (66.2%) patients were categorized as pathological grade III HSPN. Adults having crescent lesions, interstitial fibrosis and renal artery involvement significantly outnumbered child counterparts (all P<0.05). Pathological grading showed a positive correlation with 24-h urine protein (r=0.307, P=0.009), microalbuminuria (r=0.266, P=0.000) and serum globulin (r=0.307, P=0.014), and a negative correlation with serum albumin (r=0.249, P=0.037) in pediatric patients with HSPN. Among adult patients with HSPN, histopathological grading showed a positive correlation with 24-h urine protein (r=0.294, P=0.015), microalbuminuria (r=0.352, P=0.006), α1-microglobulin (r=0.311, P=0.019) and immunoglobulin G (r=0.301, P=0.023) in urine, and serum creatinine (r=0.292, P=0.018). Further, a negative correlation between serum albumin and pathological grading was also observed (r=0.291, P=0.018). In conclusion, the severity of renal pathological lesions in HSPN patients is well reflected by the levels of proteinuria. Adult patients have more severe renal histopathological changes than pediatric patients.

RESUMO

Henoch-Schönlein purpura (HSP) is a multi-organ vasculitis involving skin, joints, gastrointestinal tract, and kidneys. The present study reported a 5-year-old boy presenting with intense abdominal pain, bloody diarrhea, and protein-losing enteropathy. Investigations for infectious enteritis were negative. Esophagogastroduodenoscopy showed swelling and erythematous mucosa with hemorrhagic spots at duodenal bulb to the third part of duodenum. Histopathology of endoscopic biopsies revealed non-specific duodenitis. HSP was suspected, based on duodenitis and the presence of inflammatory markers without identifiable causes. Corticosteroid was started resulting in marked improvement of his clinical symptoms. Two weeks later, he developed nephrotic-range proteinuria, thus kidney biopsy was performed. Renal histology was consistent with IgA nephropathy, supporting the diagnosis of HSP This report emphasizes that patients with HSP may not always show visible purpura, and the diagnosis requires a high index of suspicion. GI endoscopy and renal biopsy may be helpful for the diagnosis in selected patients presenting with atypical presentations.

RESUMO

Background: Renal diseases are major causes of morbidity and mortality in pediatric practice. Pediatric patients with renal disease, especially younger ones may present with nonspecific signs and symptoms unrelated to the urinary tract. Unexplained fever or failure to thrive may be the only manifestation. Most children with renal diseases in our hospital arrive very late either because of inadequate health awareness among the parents or failure of recognizing the symptoms of renal diseases at a lower health care level. This review will highlight the symptoms of renal diseases at presentation and outcomes of treatment in children in a major referral hospital. Methods: A cross-sectional retrospective chart review was done over a period of 3 years (June, 2012 to May, 2015) in 381 admitted children (Birth-17 years) at Tikur Anbessa Specialized Teaching Hospital in Addis Ababa, Ethiopia. Results: Out of 14521 pediatric ward admissions in the study period, kidney diseases accounted for 473 admissions in 381 children, accounting for 3.3% of all admissions. The three most common renal diseases observed were congenital anomalies of the kidney and urinary tract (CAKUT) seen in 127 children (26.8%), followed by nephrotic syndrome in 80 children 16.9% and acute glomerulonephritis in 58 children (12.2%). Other renal diseases observed were urinary tract infection 8.0%, urolithiasis 6.7%, Wilm's tumor 6.3%, acute kidney injury 4.2% and chronic kidney disease 4.0%. Other less frequently detected diseases were bladder exstrophy, lupus nephritis, Henock shonlein Purpura nephritis and prune-belly syndrome. Out of 381 children 207 (54.3%) recovered normal renal function, 20(5.2%) remained with proteinuria, 13(3.4%) progressed to chronic kidney disease and 11(2.9%) died. Sixty one nephrotic children (76.3%) achieved remission but 17 children (21.3%) remained with proteinuria; one steroid resistant child died of end stage renal disease. Ten children (2.6%) with different renal diseases were lost to follow-up and 5 (1.3%) discharged against medical advice. Conclusions: This data reflects that many of the renal diseases are preventable or potentially curable. Therefore, improvement of pediatric renal services and training of health workers would help in early detection and treatment of these conditions leading to reduction in their morbidity and mortality.

RESUMO

BACKGROUND: Henoch-Schönlein purpura (HSP) mainly affects children, but age is also thought to be an important prognostic factor. Kidney involvement is a major cause of mortality in HSP patients. The purpose of this study was to analyze the clinicopathological correlations between adults and children. METHODS: A total of 208 children and 75 adult patients with HSP nephritis (HSPN) were evaluated. All patients underwent a renal biopsy. RESULTS: Extra-renal symptoms (arthritis and abdominal pain) were more common in the pediatric patient group than in the adult group (P < 0.05), but renal symptoms (edema and hypertension) were relatively rare (P < 0.05). A significant positive correlation was noted between pathological type and clinical type (P < 0.01). Pathological activity was positively related to renal failure, abdominal pain, microscopic hematuria, hypertension, and proteinuria (P < 0.05). Pathological chronicity was positively associated with age, duration of follow-up since the onset of palpable purpura, renal failure, lower extremity edema, hypertension, and proteinuria (P < 0.05). CONCLUSIONS: Various clinicopathological differences exist between children and adults with HSPN. Massive proteinuria, renal failure, and abdominal pain usually correlated with severe pathology. Renal biopsy should be performed in both pediatric and adult HSPN patients with repeated hematuria and/or consistent minimal proteinuria.
