<b><i>Introduction:</i></b> 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. <b><i>Methods:</i></b> 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 &#x3e;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. <b><i>Results:</i></b> 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 m<sup>2</sup> versus baseline (upon admission) in the AKI and non-AKI groups, respectively. The incidence of AKI was comparable between asymptomatic (4.8%, <i>n</i> = 3/62) and symptomatic (3.7%, <i>n</i> = 19/519) patients. <b><i>Conclusion:</i></b> 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 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 &gt;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.

Non-Hodgkin’s lymphoma is reportedly common in Africa; however, there is limited data on renal involvement. Acute kidney injury only at presentation is rare for lymphoproliferative malignancies. A 7-year old presented to our facility with a 2-week history of progressive abdominal distension and pain, examination revealed anasarca and hypertension. On further evaluation, there were bilateral nephromegaly, acute kidney injury (AKI) and cytomorphological findings suggestive of lymphoma. Patient management was mostly supportive, and evolution was unfavourable leading to his demise. We discuss diagnostic and therapeutic challenges due to unavailability of state-of-the-art facilities in resource-constrained settings.

AbstractIntroduction:There are little data about renal follow-up of neonates after cardiovascular surgery and no guidelines for long-term renal follow-up. Our objectives were to assess renal function follow-up practice after neonatal cardiac surgery, evaluate factors that predict follow-up serum creatinine measurements including acute kidney injury following surgery, and evaluate the estimated glomerular filtration rate during follow-up using routinely collected laboratory values.Methods:Two-centre retrospective cohort study of children 5–7 years of age with a history of neonatal cardiac surgery. Univariable and multivariable analyses were performed to determine factors associated with post-discharge creatinine measurements. Glomerular filtration rate was estimated for each creatinine using a height-independent equation.Results:Seventeen of 55 children (30%) did not have any creatinine measured following discharge after surgery until the end of study follow-up, which occurred at a median time of 6 years after discharge. Of the 38 children who had the kidney function checked, 15 (40%) had all of their creatinine drawn only in the context of a hospitalisation or emergency department visit. Acute kidney injury following surgery did not predict the presence of follow-up creatinine measurements.Conclusions:A large proportion of neonates undergoing congenital heart repair did not have a follow-up creatinine measured in the first years following surgery. In those that did have a creatinine measured, there did not appear to be any identified pattern of follow-up. A follow-up system for children who are discharged from cardiac surgery is needed to identify children with or at risk of chronic kidney disease.

Chronic Renal Impairment

Renal involvement in sarcoidosis is common and often under-recognized. The most frequent manifestation is acute kidney injury secondary to hypercalcaemia and granulomatous tubulointerstitial nephritis. The latter can lead to both acute kidney injury and to slowly progressive chronic renal impairment with concomitant chronic damage seen on histology. This chapter describes the types of renal disease that may occur in sarcoidosis and the pathogenesis, clinical presentation, diagnosis, and treatment of the patient with sarcoidosis. Corticosteroid therapy is the cornerstone of therapy. In patients with granulomatous tubulointerstitial nephritis, the authors recommend long-term, low-dose maintenance steroids.

Collapsing Glomerulopathy

Abstract Background and Aims Hemophagocytic lymphohistiocytosis (HLH) is a severe hyperinflammatory syndrome induced by aberrantly activated macrophages and cytotoxic T cells. The primary (genetic) form, caused by mutations affecting lymphocyte cytotoxicity and immune regulation, is most common in children, whereas the secondary (acquired) form is most frequent in adults. Secondary HLH is commonly triggered by infections or malignancies but may also be induced by autoinflammatory/autoimmune disorders, in which case it is called macrophage activation syndrome. The diagnosis of HLH in adults should be based on the HLH-2004 diagnostic criteria in conjunction with clinical judgment and the patient’s history. Renal involvement has previously been reported in 24 adult cases, mostly as acute renal failure. Collapsing glomerulopathy is extremely rare with only six previous cases reported in the literature. Case presentation We report the case of an African man, 31 years old, presented with fever, acute kidney injury: serum creatinine 10.3 mg/dl; urine protein 600 mg/dl, macrohematuria, ANA/ANCA were negative, low serum C3, organomegaly, anemia, thrombocytopenia, hypertriglyceridemia, hypofibrinogenemia, hyperferritinemia, direct and indirect antiglobulin (Coombs) tests were negative, low haptoglobin; elevated LDH; normal partial thromboplatin time. Peripheral blood smear examination reveal few schistocytes. ADAMTS13 activity was found to be 25%. HBV-DNA and HIV were negative. Anticardiolipin antibodies were negative. Lab exam suggested the relapse of an EBV infection and primary mycoplasma infection. Because of uremic symptoms and persisting oliguria we started replacement therapy by hemodialysis. Plasmapheresis was started because of suspected thrombotic microangiopathy. Suprisingly the kidney biopsy was consistent with collapsing glomerulopathy with evidence of tubular injury while the bone marrow biopsy diagnosed an EBV NK/T-Cell lymphoma. During the course of his hospitalization, the patient suffered high fever. C-reactive protein, WBC and procalcitonin levels were elevated. Antimicrobial agents were initiated, starting with ceftriaxone then upgraded to piperacillin/tazobactam and then the shifted to teicoplanin and meropenem. Blood, urine and stool cultures were negative.VRE positive, IgM Mycoplasma pneumoniae were positive; EBV PCR on bone marrow blood was positive. Malaria screening was negative. The antibiotic therapy was finally switched to doxycycline as unique agent. Steroid therapy (dexamethasone daily 40 mg) and IVIG (daily 35g) were initiated then these drug were stopped. CHOP-like regimen ( Etoposide 75 mg/m2, twice a week for two weeks then once a week until the seventh week) and Rituximab (375 mg/m2, once a week for 4 weeks) were initiated and continued for two weeks. Later on the patient died because of sepsis and multi-organ failure. Conclusions The multidisciplinary approach is very important. Physicians should be aware of HLH, because early recognition may prevent irreversible organ damage and subsequent death.4,5 In adults, HLH-associated mortality remains high, especially in patients with underlying malignancies. Collapsing glomerulopathy is the most commonly reported finding on renal biopsy. Renal prognosis appears to be poor with most patients remaining dialysis-dependent. The increased awareness of HLH, together with a more rapid diagnostic workup and new therapeutic approaches, will improve the prognosis of HLH in adults.

Background: The progression from acute kidney injury (AKI) to chronic kidney disease (CKD) is not well understood in children. Objectives: We aimed to develop a pediatric CKD definition using administrative data and use it to evaluate the association between AKI in critically ill children and CKD 5 years after hospital discharge. Design: Retrospective cohort study using chart collection and administrative data. Setting: Two-center study in Montreal, Canada. Patients: Children (≤18 years old) admitted to two pediatric intensive care units (ICUs) between 2003 and 2005. We a priori excluded patients with end-stage renal disease or no health care number. Only the first admission during the study period was included. We excluded patients who could not be linked to administrative data, did not survive hospitalization, or had preexisting renal disease. Measurements: Acute kidney injury was defined using Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Patients were defined as having CKD 5 years post-discharge if they had ≥1 CKD diagnostic code or ≥1 CKD-specific medication prescription. Methods: Chart data used to define the exposure (AKI) were merged with provincial administrative data used to define the outcome (CKD). Cox regression was used to evaluate the AKI-CKD association. Results: A total of 2235 (56% male) patients were included, and the median admission age was 3.7 years. A total of 464 (21%) patients developed AKI during pediatric ICU admission. At 5 years post-discharge, 43 (2%) patients had a CKD diagnosis. Patients with both stage 1 and stage 2-3 AKI had increased risk of a CKD diagnosis, with the adjusted hazard ratios (95% confidence intervals) of 2.2 (1.1-4.5) and 2.5 (1.1-5.7), respectively ( P < .001). Limitations: Results may not be generalizable to non-ICU patients. We were not able to control for post-discharge variables; future research should try to explore these additional potential risk factors further. Conclusions: Acute kidney injury is associated with 5-year post-discharge CKD diagnosis defined by administrative health care data.

SUMMARY Ophidic accidents are an important public health problem due to their incidence, morbidity and mortality. An increasing number of cases have been registered in Brazil in the last few years. Several studies point to the importance of knowing the clinical complications and adequate approach in these accidents. However, knowledge about the risk factors is not enough and there are an increasing number of deaths due to these accidents in Brazil. In this context, acute kidney injury (AKI) appears as one of the main causes of death and consequences for these victims, which are mainly young males working in rural areas. Snakes of the Bothrops and Crotalus genera are the main responsible for renal involvement in ophidic accidents in South America. The present study is a literature review of AKI caused by Bothrops and Crotalus snake venom regarding diverse characteristics, emphasizing the most appropriate therapeutic approach for these cases. Recent studies have been carried out searching for complementary therapies for the treatment of ophidic accidents, including the use of lipoic acid, simvastatin and allopurinol. Some plants, such as Apocynaceae, Lamiaceae and Rubiaceae seem to have a beneficial role in the treatment of this type of envenomation. Future studies will certainly find new therapeutic measures for ophidic accidents.

Background Acute kidney injury (AKI) in P. falciparum malaria infection is an important morbidity in children. The purpose of the present study was done to observe the renal involvement, associated morbidities and outcome. Methods Out of 156 patients with severe P. falciparum malaria, diagnosed on the basis of compatible clinical presentations and positive malarial parasites in the peripheral blood smear and/or histidine rich protein 2 antigen, 31 had AKI at presentation and were analyzed. Results Of 31 (19.9%) patients with AKI, 4 were classified at risk, 11 injury, and 16 failure stage, as per pRIFLE criteria (pediatric version of RIFLE [R = risk, I = injury, F = failure, L = loss E = end-stage kidney disease]). Mean age of children with AKI was 7.7 ± 3.2 years. A significantly higher proportion of patients with AKI had hypoglycemia (41.9%), pulmonary edema (32.2%), and disseminated intravascular coagulation (DIC) (29.0%) compared to those without AKI (18.4%, 4.8%, and 3.2%, respectively). Twelve patients (38.7%) required peritoneal dialysis (PD), 8 (25.8%) died, and all were in failure stage. The non-survivors had significantly higher blood urea ( p = 0.005) and serum creatinine levels ( p = 0.042), lower glomerular filtration rate ( p < 0.001), longer duration of illness ( p = 0.003), and oliguria/anuria ( p = 0.001) than survivors at admission. On logistic regression analysis, the disseminated intravascular coagulation (DIC), jaundice and parasite density (≥ 3+) were found to be significant factors contributing to mortality in children with AKI. Conclusions Acute kidney injury in falciparum malaria is one of the severe systemic complications. Duration of illness and presence of comorbidities adversely affected the outcome.
