MO386MASS SCREENING AND THE LOW RATES OF ACUTE KIDNEY INJURY AMONG COVID-19 PATIENTS IN HONG KONG

Abstract Background and Aims Renal involvement in COVID-19 under vigilant public health surveillance, including mass screening and early hospitalization is less well-characterized. We assessed renal involvement of COVID-19 patients in Hong Kong, including the association with risk factors, length of hospitalization, critical presentation and mortality. Method Linked electronic records of all confirmed patients from 5 major designated hospitals were extracted. Primary outcome was the incidence of in-hospital AKI. Secondary outcomes were AKI-associated mortality, incident RRT, intensive care admission, prolonged hospitalization and disease course (defined as >90th percentile of hospitalization duration and duration from symptom onset to discharge, respectively), and change of eGFR. Patients were further stratified into being symptomatic or asymptomatic. Results Patients were characterized by young age (median:38.4, IQR:28.4-55.8 years old) and short time (Median:5, IQR:2-9 days) from symptom onset to admission. Among the 591 patients, 22 (3.72%) developed AKI and 4 (0.68%) required RRT. AKI increased the odds of prolonged hospitalization and disease course by 2.0 and 3.5 folds, respectively. Estimated GFR 24 weeks post-discharge reduced by 7.51 and 1.06 ml/min/1.73m2 versus baseline (at admission) in the AKI and non-AKI groups, respectively. The incidence of AKI was comparable between asymptomatic (4.8%) and symptomatic (3.7%) patients. Conclusion The overall rate of AKI among COVID-19 patients in Hong Kong is low, which could be attributable to a vigilant screening program and early hospitalization. Among patients who developed in-hospital AKI, the duration of hospitalization is prolonged and kidney function impairment can persist for up to 6 months post-discharge. Mass surveillance for COVID-19 is warranted in identifying asymptomatic subjects for earlier AKI management.

Introduction: Renal involvement in COVID-19 is less well characterized in settings with vigilant public health surveillance, including mass screening and early hospitalization. We assessed kidney complications among COVID-19 patients in Hong Kong, including the association with risk factors, length of hospitalization, critical presentation, and mortality. Methods: Linked electronic records of all patients with confirmed COVID-19 from 5 major designated hospitals were extracted. Duplicated records due to interhospital transferal were removed. Primary outcome was the incidence of in-hospital acute kidney injury (AKI). Secondary outcomes were AKI-associated mortality, incident renal replacement therapy (RRT), intensive care admission, prolonged hospitalization and disease course (defined as >90th percentile of hospitalization duration [35 days] and duration from symptom onset to discharge [43 days], respectively), and change of estimated glomerular filtration rate (GFR). Patients were further stratified into being symptomatic or asymptomatic. Results: Patients were characterized by young age (median: 38.4, IQR: 28.4–55.8 years) and short time (median: 5, IQR: 2–9 days) from symptom onset to admission. Among the 591 patients, 22 (3.72%) developed AKI and 4 (0.68%) required RRT. The median time from symptom onset to in-hospital AKI was 15 days. AKI increased the odds of prolonged hospitalization and disease course by 2.0- and 3.5-folds, respectively. Estimated GFR 24 weeks post-discharge reduced by 7.51 and 1.06 mL/min/1.73 m2 versus baseline (upon admission) in the AKI and non-AKI groups, respectively. The incidence of AKI was comparable between asymptomatic (4.8%, n = 3/62) and symptomatic (3.7%, n = 19/519) patients. Conclusion: The overall rate of AKI among COVID-19 patients in Hong Kong is low, which could be attributable to a vigilant screening program and early hospitalization. Among patients who developed in-hospital AKI, the duration of hospitalization is prolonged and kidney function impairment can persist for up to 6 months post-discharge. Mass surveillance for COVID-19 is warranted in identifying asymptomatic subjects for earlier AKI management.

Abstract Background: The pathophysiology and trajectory of multiorgan involvement in post-COVID-19 syndrome is uncertain. Methods: A prospective, multicenter, longitudinal, cohort study involving post-COVID-19 patients enrolled in-hospital or early post-discharge (visit 1) and re-evaluated 28-60 days post-discharge (visit 2). Multisystem investigations included chest computed tomography with pulmonary and coronary angiography, cardiovascular and renal magnetic resonance imaging, digital electrocardiography, and multisystem biomarkers. The primary outcome was the adjudicated likelihood of myocarditis.Results: 161 patients (mean age 55 years, 43% female) and 27 controls with similar age, sex, ethnicity, and vascular risk factors were enrolled from 22 May 2020 to 2 July 2021 and had a primary outcome evaluation. Compared to controls, at 28-60 days post-discharge, patients with COVID-19 had persisting evidence of cardio-renal involvement, systemic inflammation, and hemostasis pathway activation. Myocarditis was adjudicated as being not likely (n=17; 10%), unlikely (n=56; 35%), probable (n=67; 42%) or very likely (n=21; 13%). Acute kidney injury (odds ratio, 95% confidence interval: 3.40 (1.13, 11.84); p=0.038) and low hemoglobin A1c (0.26 (0.07, 0.87); p=0.035) were multivariable associates of adjudicated myocarditis. During convalescence, compared to controls, COVID-19 was associated with worse health-related quality of life (EQ5D-5L) (p<0.001), illness perception (p<0.001), anxiety and depression (p<0.001), physical activity (p<0.001) and predicted maximal oxygen utilization (ml/kg/min) (p<0.001). These measures were associated with adjudicated myocarditis.Conclusions: The illness trajectory of COVID-19 includes persisting cardio-renal inflammation, lung damage and hemostasis activation. Adjudicated myocarditis occurred in one in eight hospitalized patients and was associated with impairments in health status, physical and psychological wellbeing during community convalescence. Public registration: ClinicalTrials.gov identifier is NCT04403607.

History Of

In the literature, occurrence of acute kidney injury (AKI) in young patients with unilateral ureteral lithiasic obstruction and without previous renal impairment is not very often reported, and the underlined pathophysiological mechanisms are poorly known; according to some studies, it is a false kidney failure, the increase in serum creatinine being due to absorbtion of obstructed urine in the affected kidney. We have conducted a retro and prospective study in order to identify the possible risk factors that can cause renal function impairment in young patients (18-40 years) with unilateral ureteral lithiasis obstruction and a normal contralateral kidney. Results. From 402 patients included in the study, 20.64% (83 cases) presented with serum creatinine ] 1.3 mg/dL. In patients with renal impairment, prevalence of male gender and history of NSAIDS use before admission were significantly higher than in non-AKI group. Serum urea/creatinine ratio, and estimated glomerular filtration rate (MDRD formula) were significantly higher, and respectively lower in AKI group. We found no significant differences between the two groups regarding age, prevalence of urinary tract infection after relief of obstruction, C-reactive protein value, and the duration of hospitalization. Conclusions. AKI in young patients with unilateral ureteral lithiasis obstruction and normal contralateral kidney is not quite a rare finding in our region. NSAIDs use can influence development of AKI, and should be used cautiously even in young patients with renal colic. In our opinion, the presence of AKI in patients with unilateral hydronephrosis demands urgent endourological intervention. Choosing conservative therapy in these patients, especially treatment with NSAIDS may aggravate the renal dysfunction.

Per Se

Staphylococcus-associated glomerulonephritis (SAGN) occurs as a complication of staphylococcal infection elsewhere in the body. Dermatomyositis (DM) can be associated with glomerulonephritis due to the disease per se. We report a case of a 40-year-old male patient with DM who presented with acute kidney injury, and was initially pulsed with methylprednisolone for 3 days, followed by dexamethasone equivalent to 1 mg/kg/day prednisolone. He was subsequently found to have SAGN on kidney biopsy along with staphylococcus bacteraemia and left knee septic arthritis. With proof of definitive infection, intravenous immunoglobulin 2 g/kg over 2 days was given and steroids were reduced. He was treated with intravenous vancomycin. With treatment, the general condition of the patient improved. On day 38, he developed infective endocarditis and died of congestive heart failure subsequently. Undiagnosed staphylococcal sepsis complicating a rheumatological disease course can lead to complications like SAGN, infective endocarditis and contribute to increased morbidity and mortality, as is exemplified by our case.

Type 2 Diabetes Mellitus (T2DM) is a main cause of chronic kidney disease (CKD) in adulthood. No studies have examined the occurrence of acute kidney injury (AKI)—that enhances the risk of later CKD—and renal tubular damage (RTD)—that can evolve to AKI—in children with onset of T2DM. We aimed to evaluate the prevalence and possible features of AKI and RTD in a prospectively enrolled population of children with onset of T2DM. We consecutively enrolled 10 children aged 12.9 ± 2.3 years with newly diagnosed T2DM. AKI was defined according to the KDIGO criteria. RTD was defined by abnormal urinary beta-2-microglobulin and/or tubular reabsorption of phosphate (TRP) < 85% and/or fractional excretion of Na > 2%. None of the patients developed AKI, whereas 3/10 developed RTD with high beta-2-microglobulin levels (range: 0.6–1.06 mg/L). One of these three patients also presented with reduced TRP levels (TRP = 70%). Proteinuria was observed in two out of three patients with RTD, while none of patients without RTD had proteinuria. Patients with RTD presented higher beta-2-microglobulin, acute creatinine/estimated basal creatinine ratio, and serum ketones levels compared with patients without RTD. In conclusion, in our pilot observation, we found that none of the 10 children with T2DM onset developed AKI, whereas three of them developed RTD.

Stage Renal Disease

Background: Renal involvement is a common and severe complication of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), potentially resulting in a pauci-immune necrotizing and crescentic ANCA glomerulonephritis (GN) with acute kidney injury (AKI), end-stage renal disease (ESRD) or death. There is recent evidence that the degree of proteinuria at diagnosis is associated with long-term renal outcome in ANCA GN. Therefore, we here aimed to systematically describe the association between proteinuria and clinicopathological characteristics in 53 renal biopsies with ANCA GN and corresponding urinary samples at admission. Methods: A total number of 53 urinary samples at admission and corresponding renal biopsies with confirmed renal involvement of AAV were retrospectively included from 2015 to 2021 in a single-center study. Results: Proteinuria correlated with myeloperoxidase (MPO) subtype, diagnosis of microscopic polyangiitis (MPA) and severe deterioration of kidney function. Proteinuria was most prominent in sclerotic class ANCA GN and ANCA renal risk score (ARRS) high risk attributed to nonselective proteinuria, including both glomerular and tubular proteinuria. Finally, there was no association between proteinuria and systemic disease activity, suggesting that proteinuria reflected specific renal involvement in AAV rather that systemic disease activity. Conclusions: In conclusion, proteinuria correlated with distinct clinicopathological characteristics in ANCA GN, mostly attributed to a reduced fraction of normal glomeruli. Furthermore, proteinuria in ANCA GN reflected specific renal involvement in AAV rather than systemic disease activity. Therefore, urinary findings could further improve our understanding of mechanisms promoting kidney injury and progression of ANCA GN.

Background:Although children and adolescents are less likely to develop COVID-19 and generally show milder disease courses, it is unclear what impact the SARS-CoV2 infection has on children and adolescents with rheumatic and musculoskeletal disease (RMD). Due to their underlying disease as well as therapeutic immunosuppression these patients may be at higher risk of being more severely affected by SARS-CoV2. Furthermore, SARS-CoV2 infection might trigger a flare of the underlying disease.Objectives:To evaluate clinical characteristics and disease course of COVID-19 in children and adolescents with RMD and to analyze possible effects of SARS-CoV2 infection on the underlying disease under different therapeutic regimens.Methods:Data from juvenile patients with RMD recorded via the SARS-CoV2 questionnaire within the National Pediatric Rheumatology Database and the registry for hospitalized children and adolescents with COVID-19 of the German Society for Pediatric Infectious Diseases were analyzed. In addition to age, sex and diagnosis, information was collected about the date and method of a positive SARS-CoV2 testing, reason for testing, on clinical manifestations, disease course, treatment and outcome of COVID-19, on drug therapy at the time of virus detection, on disease activity (NRS 0 – 10, 0 = best) of the underlying disease at the last visit before and after the SARS-CoV2 infection.Results:From April 17th 2020 until January 25th 2021, data of 67 patients with RMD and confirmed SARS-CoV2 infection were collected. Mean age was 13.5 ± 3.9 years with equal sex distribution. The majority of patients were diagnosed with juvenile idiopathic arthritis (JIA, 64%), 12 (18%) patients had an autoinflammatory disease (FMF, CAPS, PFAPA, TRAPS) and 5 (7%) a connective tissue disease. Fifty-two patients (78%) were treated with a disease modifying antirheumatic drug (DMARD), 39% with a biological DMARD and 9% systemic glucocorticoids at the time of SARS-CoV-2 infection. Nineteen patients (28%) were tested for SARS-CoV-2 because of typical symptoms, the majority (67%) because of contact to an infected person. PCR was used most often (in 60 %).52 patients (78%) developed symptoms of COVID-19, 15 patients remained asymptomatic. The most common symptom of COVID-19 was rhinitis (42%) and fever (38%), followed by fatigue (34%), taste/smell disorder (33%), sore throat (27%) and cough (23%).Disease severity was graded as mild in 44 of 52 (85%) symptomatic patients, only two patients were hospitalized, one of whom required intensive care and died of cardiorespiratory failure 3 days after symptom onset. In 22 of 26 (85%) SARS-CoV2-positive patients, no relevant increase in disease activity (difference in NRS ≤ 1 before/after infection) of the underlying disease was observed 31 days after symptom onset (median, IQR 17-52 days). One patient, who had paused tocilizumab for 2 doses, experienced a flare of his seronegative polyarthritis 2 months after asymptomatic SARS-CoV-2 infection.Conclusion:In our cohort, the clinical picture of COVID-19 in children and adolescents with RMD was similar to that of healthy peers. The majority of patients showed mild disease course with good outcome under various medications, however, one patient with a severe course of COVID-19 died. In addition, SARS-CoV2 infection does not appear to have a relevant impact on the underlying disease activity, whereas discontinuation of therapy might pose a risk of flare.Disclosure of Interests:None declared.

Abstract Background Melioidosis is a potentially fatal tropical infection caused by Burkholderia pseudomallei. Kidney involvement is possible, but has not been well described. Aim This study aimed to assess the risk of acute kidney injury (AKI) and its outcomes in melioidosis. Methods A retrospective observational cohort study was performed. Case records of consecutive patients with culture-confirmed melioidosis, observed from January 1st, 2012 through December 31st, 2019 were analysed for demographics, presence of comorbidities, including chronic kidney disease (CKD), diabetes mellitus (DM), and presence of bacteraemia, sepsis, shock, AKI, and urinary abnormalities. The outcomes we studied were: mortality, need for hospitalisation in an intensive care unit (ICU), duration of hospitalization. We then compared the outcomes between patients with and without AKI. Results Of 164 patients, AKI was observed in 59 (35.98%), and haemodialysis was required in eight (13.56%). In the univariate analysis, AKI was associated with CKD (OR 5.83; CI 1.140–29.90, P = 0.03), bacteraemia (OR 8.82; CI 3.67–21.22, P < 0.001) and shock (OR 3.75; CI 1.63–8.65, P = 0.04). In the multivariate analysis, CKD (adjusted OR 10.68; 95% CI 1.66–68.77; P = 0.013) and bacteraemia (adjusted OR 8.22; 95% CI 3.15–21.47, P < 0.001) predicted AKI. AKI was associated with a greater need for ICU care (37.3% vs. 13.3%, P = 0.001), and mortality (32.2% vs. 5.7%, P < 0.001). Mortality increased with increasing AKI stage, i.e. stage 1 (OR 3.52, CI 0.9–13.7, P = 0.07), stage 2 (OR 6.79, CI 1.92–24, P = 0.002) and stage 3 (OR 17.8, CI 5.05–62.8, P < 0.001), however kidney function recovered in survivors. Hyponatremia was observed in 138 patients (84.15%) and isolated urinary abnormalities were seen in 31(18.9%). Conclusions AKI is frequent in melioidosis and occurred in 35.9% of our cases. Hyponatremia is likewise common. AKI was predicted by bacteraemia and CKD, and was associated with higher mortality and need for ICU care; however kidney function recovery was observed in survivors.

Abstract Background. Acute kidney injury (AKI) is a well recognized complication of severe malaria in adults, but the incidence and clinical importance of AKI in pediatric severe malaria (SM) is not well documented. Methods. One hundred eighty children aged 1 to 10 years with SM were enrolled between 2011 and 2013 in Uganda. Kidney function was monitored daily for 4 days using serum creatinine (Cr). Acute kidney injury was defined using the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines. Blood urea nitrogen (BUN) and Cr were assessed using i-STAT, and cystatin C (CysC) was measured by enzyme-linked immunosorbent assay. Results. Eighty-one (45.5%) children had KDIGO-defined AKI in the study: 42 (51.9%) stage 1, 18 (22.2%) stage 2, and 21 (25.9%) stage 3. Acute kidney injury evolved or developed in 50% of children after admission of hospital. There was an increased risk of AKI in children randomized to inhaled nitric oxide (iNO), with 47 (54.0%) of children in the iNO arm developing AKI compared with 34 (37.4%) in the placebo arm (relative risk, 1.36; 95% confidence interval [CI], 1.03–1.80). Duration of hospitalization increased across stages of AKI (P = .002). Acute kidney injury was associated with neurodisability at discharge in the children receiving placebo (25% in children with AKI vs 1.9% in children with no AKI, P = .002). Mortality increased across stages of AKI (P = .006) in the placebo arm, reaching 37.5% in stage 3 AKI. Acute kidney injury was not associated with neurodisability or mortality at discharge in children receiving iNO (P > .05 for both). Levels of kidney biomarkers were predictive of mortality with areas under the curves (AUCs) of 0.80 (95% CI, .65–.95; P = .006) and 0.72 (95% CI, .57–.87; P < .001), respectively. Admission levels of CysC and BUN were elevated in children who died by 6 months (P < .0001 and P = .009, respectively). Conclusions. Acute kidney injury is an underrecognized complication in young children with SM and is associated with increased mortality.

Goodpasture’S Disease

Goodpasture’s disease (anti-GBM disease) is a rare small vessels vasculitis characterized by the presence of autoantibodies directed against the glomerular basement membrane (GBM) and alveolar basement membrane. Common feature of anti-GBM disease is a combination of rapidly progressive glomerulonephritis and alveolar hemorrhage (pulmonary-renal syndrome). We present a case of atypical disease course in a young male patient who developed alveolar hemorrhage without renal failure. The only symptom of renal involvement was isolated hematuria. Plasmapheresis combined with immunosuppression (cyclophosphamide and corticosteroids) was effective. We present a review of state-of-art data on the pathogenesis and disease course of anti-GBM disease.
