Diffuse Proliferative Glomerulonephritis

Postinfectious glomerulonephritis (PIGN) is primarily a disease of childhood. It occurs after upper respiratory tract infection or skin infections. Streptococcus is the most common causative agent, but in the elderly, staphylococcus is the main culprit. In adults, PIGN is more common in immunocompromised patients, particularly diabetics and alcoholics. Here, we report the case of an elderly diabetic male who presented with severe acute kidney injury with active urinary sediment after acute gastroenteritis. Additional analyses revealed a very low serum C3 level and a normal serum C4 level. Renal biopsy showed diffuse proliferative glomerulonephritis with crescents. Direct immunofluorescence showed mesangial and capillary wall staining for C3 and IgG (2+, mesangial and segmental capillary wall, granular). Renal electron microscopy showed subepithelial hump-like electron-dense deposits. The role of steroid in the treatment of PIGN is controversial and there is no standard protocol, but our patient responded very well to steroid as he did not require hemodialysis after 2 weeks of initiation of steroid therapy. We should be aware of an atypical presentation of PIGN in elderly to ensure correct diagnosis.

Common Cause

Introduction: In the elderly, impairment of kidney function occurs. Renal diseases overlap with anatomic and functional changes related to age-related involutionary processes. Mortality among patients with acute renal injury is approximately 50%, despite advances in treatment and diagnosis of AKI. The aim: To assess the incidence of acute kidney injury in elderly patients and to analyze the causes of acute renal failure depending on age. Materials and methods: A retrospective analysis included medical documentation of patients hospitalized in the Nephrology Clinic during the 6-month period. During this period 452 patients were hospitalized in the clinic. A group of 77 patients with acute renal failure as a reason for hospitalization was included in the study. Results: The prerenal form was the most common cause of AKI in both age groups. In both age groups, the most common cause was dehydration; in the group of patients up to 65 years of age, dehydration was 29.17%; in the group of people over 65 years - 43.39%. Renal replacement therapy in patients with AKI was used in 14.29% of patients. In the group of patients up to 65 years of age hemodialysis was 16.67% and above 65 years of age. -13.21% of patients. The average creatinine level in the group of younger patients at admission was 5.16 ± 3.71 mg / dl, in the group of older patients 3.14 ± 1.63 mg / dl. The size of glomerular filtration GFR in the group of younger patients at admission was 21.14 ± 19.54 ml / min, in the group of older patients 23.34 ± 13.33 ml / min. Conclusions: The main cause of acute kidney injury regardless of the age group was dehydration. Due to the high percentage of AKI in the elderly, this group requires more preventive action, not only in the hospital but also at home.

Abstract Background and Aims It is evident that Chronic Kidney Disease (CKD) influences the risk of developing AKI (Acute Kidney Injury) and recent studies suggest that CKD patients who experienced an episode of AKI are more likely to progress to end stage renal disease (ESRD) than patients without CKD. AKI-CKD association might originate from common comorbidities associated with both AKI and CKD, such as diabetes and/or hypertension, and concurrent increase in interventions leading to frequent exposure to various nephrotoxins. AKI in the elderly has been shown to increase the risk of progression to CKD to ESRD. AKI is common in critically ill patients, and those patients with the most severe form of AKI, requiring RRT, have a mortality rate of 50–80 %. Patients with an eGFR <45 ml/min per 1.73m2 who experienced an episode of dialysis-requiring AKI were at very high risk for impaired recovery of renal function. Our aim was to determine the reasons that initiate hemodialysis (renal decompensation) in patients with regular follow-up in the low clearance polyclinic without renal replacement treatment (RRT). Method The retrospective study included predialysis CKD patients who had followed up regularly and had undergone RRT in recent 4 years. Data on baseline characteristics and medical history were obtained from patient hospital records. Results Of the 228 patients, 155 (68%) were male and 73 (32%) were female. The mean age was 58 years (45-66). Diabetes Mellitus was the first in the etiology of CKD (26,3 %), the second was unknown (12,7 %), the third was hypertension (11,8 %). 145 patients (63,6%) underwent regular hemodialysis (HD) (62 years, 55-69), 25 patients (11%) began peritoneal dialysis (PD), 58 patients (25%) had renal transplantation. 52 patients underwent HD with renal decompensation, 22 (%42,3) had working arteriovenous fistula (AVF). There was no decompensation in patients with PD or transplantation plan. 34 patients started HD because of infections (65%), 8 patients (15%) after operations (4 was Coronary Artery Bypass Grafting-CABG), 6 patients (%11,5) after coronary angiography, 4 patients (7,5%) with cardiac decompensation. 2 patients died during the hospitalisation for infections. Of 145 HD patients, 89 (%61,4) had AVF. The patients who had renal decompensation were more older 63 (58-70), have lower Hgb 9,7 g/L (9,1-10,7) and albumin 3,5 g/L (3,2-3,9) level (p<0,05). There was no difference in eGFR at the beginning of HD between renal decompensation and other HD patients. 42 patients did not undergo HD at the time we suggested during visits. Of them 9 patients (%21) had renal decompensation (6 infections,3 CABG), 17 patients (%40) had AVF. 3 of them died. The others underwent HD for uremic complications. Conclusion We have shown that infections are as the leading cause of renal decompensation. Most of our patients who started to RRT from our low clearance outpatient clinic have chosen HD for RRT. Prevention of infections via vaccination programs or early diagnosis at regular policlinic or telephone visits, and informing patients adequately about nephrotoxic drugs or the conditions that may cause renal decompensation are among the first tasks of the predialysis outpatient clinic. Transition of CKD patients to RRTs, with proper preparation, neither late nor early- at the most appropriate time- should be among in our goals. This may reduce the cost of ESRD patients.

AbstractIt is unclear whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can directly infect human kidney, thus leading to acute kidney injury (AKI). Here, we perform a retrospective analysis of clinical parameters from 85 patients with laboratory-confirmed coronavirus disease 2019 (COVID-19); moreover, kidney histopathology from six additional COVID-19 patients with post-mortem examinations was performed. We find that 27% (23/85) of patients exhibited AKI. The elderly patients and cases with comorbidities (hypertension and heart failure) are more prone to develop AKI. Haematoxylin & eosin staining shows that the kidneys from COVID-19 autopsies have moderate to severe tubular damage. In situ hybridization assays illustrate that viral RNA accumulates in tubules. Immunohistochemistry shows nucleocapsid and spike protein deposits in the tubules, and immunofluorescence double staining shows that both antigens are restricted to the angiotensin converting enzyme-II-positive tubules. SARS-CoV-2 infection triggers the expression of hypoxic damage-associated molecules, including DP2 and prostaglandin D synthase in infected tubules. Moreover, it enhances CD68+ macrophages infiltration into the tubulointerstitium, and complement C5b-9 deposition on tubules is also observed. These results suggest that SARS-CoV-2 directly infects human kidney to mediate tubular pathogenesis and AKI.

Vesiculobullous eruptions in the elderly represent a diverse range of varying pathophysiologies and can present a significant clinical dilemma to the diagnostician. Diagnosis requires a careful review of clinical history, attention to detail on physical and histomorphological examination, and appropriate immunofluorescence testing. We describe the case of a 73-year-old female who presented to our hospital with a painful blistering skin rash developed over 2 days. Examination of the skin was remarkable for numerous flaccid hemorrhagic bullae on a normal-appearing nonerythematous skin involving both the upper and lower extremities. Histopathology of the biopsy lesion showed interface change at the epidermo-dermal region with subepidermal blister formation, mild dermal fibrosis, and sparse interstitial neutrophilic infiltrate. Immunohistological analysis was significant for positive IgG basement membrane zone antibodies with a dermal pattern of localization on direct immunofluorescence and positive IgG antinuclear antibodies on indirect immunofluorescence. Evidence of antibodies to type VII collagen suggested the diagnosis of epidermolysis bullosa acquisita versus bullous systemic lupus erythematosus (BSLE). A diagnosis of BSLE was made based on positive American College of Rheumatology criteria, acquired vesiculo-bullous eruptions with compatible histopathological and immunofluorescence findings. This case illustrates one of many difficulties a physician encounters while arriving at a diagnosis from a myriad of immunobullous dermatoses. Also, it is important for internists and dermatologists alike to be aware of and differentiate this uncommon and nonspecific cutaneous SLE manifestation from a myriad of disorders presenting with vesiculobullous skin eruptions in the elderly.

Abstract Background We aimed to evaluate prevalence of acute kidney injury (AKI) and its risk factors in children hospitalized for acute gastroenteritis (AGE) to identify early predictors of AKI. Methods We retrospectively collected clinical and biochemical data of 114 children (57.9% male; mean age 2.9 ± 2.8 years) hospitalized for AGE. AKI was defined according to Kidney Disease/Improving Global Outcomes creatinine criteria. We considered basal serum creatinine as value of creatinine estimated with Hoste (age) equation assuming basal eGFRs were median age-based eGFR normative values for children ≤ 2 years of age, and eGFR 120 mL/min/1.73m2 for children > 2 years. Univariate and multivariate logistic regression models were used to explore associations with AKI. We included in multivariate analyses only variables with significant p after Bonferroni correction. Results AKI was found in 28/114 (24.6%) patients. No patients required hemodialysis, 2 (1.8%) reached AKI stage 3, 2 (1.8%) AKI stage 2, and 24 (21.0%) AKI stage 1. Mean length of stay was 3.6 ± 1.2, 5.0 ± 1.8, and 10.5 ± 5.8 days, for patients with no, mild, and severe AKI (p < 0.001), respectively. Duration of symptoms before hospitalization (OR = 2.5; 95% CI = 1.3–5.0; p = 0.006), dehydration > 5% (OR = 43.1; 95% CI = 5.4–344.1; p = < 0.001), and serum bicarbonate levels (OR = 1.6; 95% CI = 1.2–2.1; p = 0.001) were independent predictors of AKI. Conclusions About one quarter of patients hospitalized for AGE may suffer from AKI with a longer stay for patients with more severe AKI. Particular attention, however, should be paid to volemia and kidney health of patients with AGE especially in the presence of increased duration of symptoms before hospitalization, dehydration, and lower serum bicarbonate levels.

Metastatic Pulmonary Calcification

Metastatic pulmonary calcification: a case report and literature overview Ground-glass opacities have a broad differential diagnosis, including infectious, metabolic, inflammatory and malignant causes. This case presents an underdiagnosed entity of dense ground-glass opacities, namely metastatic pulmonary calcifications (MPC). This is a benign metabolic disease characterised by the deposition of calcium in the lungs, mostly described in patients with chronic kidney injury and secondary hyperparathyroidism. The majority of the patients require no treatment, but in some cases it may lead to irreversible lung damage. Clinical and radiological features, as well as the patient’s history, are crucial to make a correct diagnosis since MPC has a relatively specific appearance on imaging. This case study discusses the medical history and imaging appearance of a 44-year-old woman with MPC, followed by a literature overview.

Abstract Background and Aims Acute kidney injury (AKI) is common in the elderly due to physiologic renal aging and underlying pathologies. Few studies focused on AKI in Tunisian elderly. The aim of our study was to highlight the epidemiological, clinical, etiological, therapeutic, and progressive characteristics of AKI in elderly. Method We conducted a descriptive retrospective study of AKI in patients admitted to our department over a period of 04 years from 01/01/2014 to 31/12/2017. Results We collected 40 patients including 25 women and 15 men with a sex ratio of 1.66. The mean age was 74 [65-87] years. We noted the presence of pre-existing chronic kidney disease in 58% of cases, diabetes in 50% of cases and hypertension in 73% of cases. Polypharmacy was found in 40% of cases. AKI was symptomatic in 80% of cases and found on a routine check-up in 20% of cases. Mean creatinine was 612+/-334 µmol/l. AKI was pre-renal in 37% and parenchymal in 63% of cases. Iatrogenic origin was found in 33% of cases. Renal biopsy was performed for diagnostic purposes in 6 cases. Haemodialysis was necessary in 50% of cases. Etiopathogenic treatment was initiated in 73% of cases. Intra-hospital mortality was 10%, recovery of renal function (RF) was partial in 40 % of cases and total in 20 % of cases. Follow-up time was 16 +/- 23.2 months. And at the last news, recovery of renal function (RF) was partial in 7 cases and total in 10 cases, 6 patients kept a chronic renal failure (CRF), among them 3 cases had and end-stage of CRF. Conclusion AKI is a frequent pathology in the elderly and its severity is linked to mortality and the transition to chronicity. Iatrogenic causes are frequent and preventable in this population, hence the major interest of prevention.

BACKGROUND The criteria for the diagnosis of kidney disease outlined in “The Kidney Disease: Improving Global Outcomes (KDIGO)” are based on a patient’s current, historical and baseline data. The diagnosis of acute (AKI), chronic (CKD) and acute-on-chronic kidney disease requires past measurements of creatinine and back-calculation and the interpretation of several laboratory values over a certain period. Diagnosis may be hindered by unclear definition of the individual creatinine baseline and rough ranges of norm values set without adjustment for age, ethnicity, comorbidities and treatment. Classification of the correct diagnosis and the sufficient staging improves coding, data quality, reimbursement, the choice of therapeutic approach and the patient’s outcome. OBJECTIVE With the help of a complex rule-engine a data-driven approach to assign the diagnoses acute, chronic and acute-on-chronic kidney disease is applied. METHODS Real-time and retrospective data from the hospital’s Clinical Data Warehouse of in- and outpatient cases treated between 2014 – 2019 is used. Delta serum creatinine, baseline values and admission and discharge data are analyzed. A KDIGO based standard query language (SQL) algorithm applies specific diagnosis (ICD) codes to inpatient stays. To measure the effect on diagnosis, Text Mining on discharge documentation is conducted. RESULTS We show that this approach yields an increased number of diagnoses as well as higher precision in documentation and coding (unspecific diagnosis ICD N19* coded in % of N19 generated 17.8 in 2016, 3.3 in 2019). CONCLUSIONS Our data-driven method supports the process and reliability of diagnosis and staging and improves the quality of documentation and data. Measuring patients’ outcome will be the next step of the project.
