Abstract Background and Aims Renal biopsy is the “gold standard” for diagnosis of lupus nephritis (LN). It is necessary for classification and is the basis for treatment strategy decisions. This study was carried out in order to analyse the results of renal biopsy in LN patients, its effect on treatment and predictors for remission in an Egyptian cohort. Method The results of renal biopsies of LN patients undergoing regular follow up in the outpatient clinic of Mansoura Nephrology and Dialysis Unit (MNDU), Mansoura University Hospital, Egypt in the period between October 2017 and September 2019 were reviewed. The histopathological data were analyzed and correlated to the clinical data of the study group. Results A total of 100 LN patients with documented renal biopsy were enrolled in this study. The median age of the patients was 29 years. Most of the patients were females (n=89). Serum creatinine at presentation ranged from 0.57 to 13.5 mg/dl (median 1.3 mg/dl). Class IV (diffuse proliferative) LN was the most frequently encountered class, followed by Classes III, V, II and VI respectively, while class I was detected in only one patient. In proliferative classes (III and IV), the total score of activity indices, ranged from 0 to 16 (minimum–maximum). Mesangial hypercellularity was the most frequent encountered active lesions. Total score of chronicity indices ranged from 0 to 10 (minimum-maximum). Interstitial fibrosis was the most frequent chronicity index. Remission was achieved in 73 patients. Patients who achieved remission had lower serum creatinine and lower pathological chronicity score. In a multivariate logistic regression analysis, serum creatinine at presentation was the strongest predictor for renal remission in this cohort and chronicity index was the strongest predictor in proliferative classes (III and IV). Receiver operating characteristic curve (ROC curve) was done to identify the cutoff point of serum creatinine which can indicate the probability of renal recovery in proliferative and non-proliferative classes (n=100) and in proliferative classes only (n=73). A serum creatinine value of 1.65 mg/dl or less identifies the probability of renal recovery with 76% sensitivity and 71% specificity in proliferative and non-proliferative classes . A chronicity index value of 6 or less identifies the probability of renal recovery with 93% sensitivity and 58% specificity. Conclusion Renal biopsy is a must in LN to guide treatment and prognosis. In this Egyptian cohort, serum creatinine at presentation and pathological chronicity index score are the strongest predictors of renal response in LN patients.

Aim We aim to describe the pattern of response to treatment in a cohort of Egyptian lupus nephritis (LN) patients and to define variable prognostic factors. Methods We retrospectively analyzed records of 928 systemic lupus erythematosus (SLE) patients (898 females, 30 males) with biopsy-confirmed LN seen between 2006 and 2012 at Cairo University hospitals. Results Our study involved 928 SLE patients with a mean age of 26.25 ± 6.487 years, mean LN duration at time of renal biopsy 6.48 ± 4.27 months, mean SLEDAI 28.22 ± 11.7, and mean follow-up duration of 44.14 ± 17.34 months. Induction treatment achieved remission in 683 patients. Remission was achieved in all 32 patients with class II LN, compared to 651/896 (72.7%) patients in classes III, IV, and V. Induction by intravenous (IV) cyclophosphamide achieved response in 435/575 (75.7%) patients, while induction by mycophenolate mofetil (MMF) resulted in response in 216/321 (67.3%) patients ( p = 0.0068). Nephritic flares were least observed when MMF was used for maintenance (30/239 (12.6%) patients), compared to 71/365 patients (19.5%) ( p = 0.0266) when azathioprine (AZA) was used, and 22/79 patients (27.8%) ( p = 0.002) with IV cyclophosphamide. Class IV LN, high chronicity index, presence of crescents, and interstitial fibrosis in biopsies were all associated with chronic kidney disease (CKD) development eventually ( p < 0.001, p = 0.005, p = 0.012, and p = 0.031, respectively). By the end of the study duration, 305 (32.7%) patients had CKD. Logistic regression detected that high baseline serum creatinine, failure to achieve remission, hypertension, and nephritic flare were the main risk factors for poor renal outcome ( p < 0.001, p < 0.001, p = 0.004, and p < 0.001, respectively). The 5 years’ mortality was 69 (7.4%) patients with sepsis being the main cause of death. Conclusion IV cyclophosphamide superseded as induction treatment, while MMF was the best maintenance treatment. High serum creatinine, hypertension, and nephritic flare were the main risk factors for poor renal outcome.

Abstract Background To evaluate histological active and chronic lesions associated with proteinuria and serum creatinine (SCr) level as common clinical endpoints in many clinical trials for lupus nephritis (LN).Methods One hundred and nineteen patients from 1990 to 2015 with LN class III, IV, and V, as defined by the International Society of Nephrology/Renal Pathology Society classification, were enrolled. Multiple regression analysis was performed to explore semiquantitative histological variables related to urinary protein and SCr levels.Results The mean age of enrolled patients was 45 years and 79% were female. The mean SCr level was 0.87 mg/dl and mean urinary protein was 3.00 g/gCr at the time of the renal biopsy. Class IV (71%) was the most common type, followed by class III (17%) and class V (13%). Multicollinearity was confirmed between monocellular infiltration (variance inflation factor [VIF] = 10.22) and interstitial fibrosis (VIF = 10.29) and between karyorrhexis (VIF = 4.14) and fibrinoid necrosis (VIF = 4.29). After excluding fibrinoid necrosis and monocellular infiltration because of multicollinearity, only urinary protein level was correlated with wire loop (β−coefficient [β]: 1.09 and confidence interval [CI]: 0.35 to 1.83), and SCr level was correlated with glomerular sclerosis (β: 1.08 and CI: 0.43 to 1.74) by multiple regression analysis.Conclusion As urinary protein and SCr levels could not reflect active lesions quantitatively, they might be difficult to be evaluated for response to induction remission treatments in patients with LN.

Objective.To describe the incidence of recovery of both vancomycin-resistant enterococci (VRE) and methicillin-resistantStaphylococcus aureus(MRSA) from culture of a single clinical specimen, to describe the clinical characteristics of patients from whom these specimens were recovered, and to identify the risk factors of these patients.Design.A retrospective cohort and case-control study.Setting.A tertiary care university hospital and referral center in Seoul, Korea.Methods.We identified 61 case patients for whom a single clinical specimen yielded both VRE and MRSA on culture, and 122 control patients for whom any clinical specimen yielded only VRE on culture. The control patients were selected by matching 2 :1 with the case patients for age, sex, and first date of sampling that led to isolation of VRE or both VRE and MRSA among 1,536 VRE-colonized patients from January 1, 2003, through December 31, 2006. To identify patient risk factors for the recovery of both VRE and MRSA in a single clinical specimen, we performed univariate comparisons between the 2 groups and then multivariate logistic regression analysis.Results.The incidence of recovery of both VRE and MRSA from culture of a single clinical specimen was 3.97% (for 61 of 1,536 VRE-colonized patients) over 4 years. Among these 82 single clinical specimens, the most common type was wound specimens (26.8%), followed by lower respiratory tract specimens (18.3%), urine specimens (17.1%), and catheter tips (15.9%). Of the 61 case patients, 14 (23.0%) had 2 or more single clinical specimens that yielded both VRE and MRSA on culture, and the longest interval from the first sampling that yielded both organisms to the last sampling that yielded both was 174 days. Independent patient risk factors for the presence of both VRE and MRSA in a single clinical specimen were chronic renal disease (odds ratio [OR], 7.00;P= .012), urinary catheterization (OR, 3.36;P= .026), and longer total cumulative duration of hospital stay within the previous year (OR, 1.03;P< .001).Conclusion.We confirmed that the recovery of VRE and MRSA from a single clinical specimen occurs continually. Because prolonged cell-to-cell contact can facilitate transfer ofvanA,close observation and surveillance for vancomycin-resistantS. aureus, especially among patients with risk factors for the recovery of both VRE and MRSA from a single clinical specimen, should be continued.

Abstract Background and Aims Glomerular diseases (GDs) impose a substantial burden on patients and health care systems, and they are considered a major cause of end-stage renal disease (ESRD) worldwide. Morbidity and mortality have shown to be substantially higher in patients with GDs than in the general population. In Egypt, there is yet no available national registry for GDs, and GDs outcome is not adequately studied. Therefore, it is of considerable interest to study patterns and outcomes of GDs in our locality. Method Patients with features suggesting GDs presenting to Mansoura nephrology and dialysis unit (MNDU) were recruited in this study between 1 July 2017 and 30 June 2018, and those with biopsy-proven GDs were prospectively followed up for a minimum of 6 months or until either death or reaching ESRD. ESRD was defined as initiation of long-term dialysis or eGFR persistently &lt;15 ml/min per 1.73 m2 during follow up visits. Enrolled patients were subjected to through history taking and clinical examination. Biopsies were independently examined by two pathologists blinded to the clinical data. The study outcomes were to identify the GDs subtype frequencies, and to identify the frequency of those achieving either renal recovery, progression to ESRD or death from all-cause mortality. Logistic regression analysis was carried out to identify the potential predictors for renal recovery. Results Sixty-six patients (21 males and 45 females) with biopsy-proven GDs were included and completed the required period of follow up. The median age of the studied patients was 32 years (IQR 23 - 46.45). Fifty percent of the cases had hypertension and only one patient had was diabetic. The main indications for renal biopsy were unexplained kidney function decline (62%) followed by subnephrotic (23%) and nephrotic presentation (15%). Diffuse proliferative GN followed by MPGN and sclerosing GN were the most frequently encountered histopathological patterns. Primary and secondary GDs constituted 30.3% and 69.7% respectively. Lupus nephritis (LN) was the most common cause of secondary GDs and class IV LN was the most frequently encountered class accounting for 16 cases (51.6%) of patients with lupus. By the end of 6-month follow up, renal recovery was achieved in 30 patients (45.5%), 21 patients (31.8%) progressed to ESRD and 7 patients (10.6%) had died. Urban residency and total renal chronicity score were the most significant predictors of renal recovery. Conclusion Diffuse proliferative GN is the most common histopathological pattern, and secondary GDs, particularly those related to lupus, are more frequently encountered than primary GDs in our center. Unfortunately, quick complete recovery is not the rule and is possibly predictable by less chronic changes in biopsy.

Background: A revision of the International Society of Nephrology/Renal Pathology Society (ISN/RPS) classification for lupus nephritis has been published in 2018. The current study aimed to verify the utility of this system. Materials and Methods: A total of 101 lupus nephritis patients from a large Chinese cohort who underwent renal biopsy in Peking University First Hospital were reevaluated by 2 renal pathologists, who had no knowledge of the clinical findings. The association between clinical data at the time of initial renal biopsy and follow-up and pathological features were further analyzed on all patients selected. Results: The mean age of the cohort was 33 years with a male/female ratio of 1:9, and a median follow-up period of 128 months. The presence and extent of mesangial hypercellularity, endocapillary hypercellularity, global and segmental glomerulosclerosis, neutrophil exudation/karyorrhexis, glomerular hyaline deposits, extracapillary proliferation (crescents), tubular atrophy/interstitial fibrosis, and interstitial inflammation were significantly correlated with several clinical renal injury indices (systemic lupus erythematosus disease activity index, serum creatinine value, proteinuria, and C3 level) at the time of biopsy. By multivariable Cox hazard analysis, fibrous crescents, tubular atrophy/interstitial fibrosis, and the modified National Institutes of Health chronicity index were independent risk factors for patients’ composite renal outcomes (hazard ratio [HR] 4.100 [95% CI 1.544–10.890], p = 0.005; HR 8.584 [95% CI 2.509–29.367], p = 0.001; and HR 3.218 [95% CI 1.138–9.099], p = 0.028; respectively). Conclusions: The 2018 revision of the ISN/RPS classification for lupus nephritis has utility for prediction of clinical renal outcomes.

BACKGROUND Neurosurgical patients are admitted to hospital via emergency department admissions is common; however, studies designed to describe their features are not available. OBJECTIVE This study aims to investigate the characteristics of patients admitted to the neurosurgery department in an emergency manner by using medical big data integration and application platform (internet cloud platform). METHODS We derived data from the internet cloud platform of West China Hospital, Sichuan University. The data of consecutive patients admitted to the department of neurosurgery as emergency admissions in a non-profit tertiary care university hospital was collected. Data on demographic information, clinical characteristics and outcomes were collected and evaluated through the platform. Patients were stratified into five disease groups (vascular disease, trauma, oncology, spine and others) according to their main diagnoses at the time of admission. RESULTS A total of 4,149 cases (median age 52 years, 54.5% male) were identified in this study. Vascular disease was the most common reason for emergency admission (73.5%). Significant differences were found among the five disease groups in sex (P<.001), age (P<.001), surgery (P<.001) and season (P=.009) but not in the length of stay (P=.784). Multivariate logistic regression analysis identified male sex, older age, short length of stay, surgery not performed and disease type (particularly trauma) as independently associated with in-hospital mortality. CONCLUSIONS By using internet cloud platform, we identified significant demographic and clinical differences among neurosurgical patients admitted to the neurosurgery department as an emergency. These findings may assist health care practitioners in shifting tasks and clinical resources toward those patients who may benefit from particular intervention approaches.

Few studies have correlated serum biomarkers with renal histology, the gold standard for renal activity, in lupus nephritis (LN). We tested a panel of autoantibodies and complement at the time of kidney biopsy and after treatment. Anti-dsDNA, anti-nucleosome, anti-ribosome P, and anti-C1q antibodies and C3/C4 were measured in 107 patients with LN at the time of renal biopsy and after 6–12 months and were correlated with clinical/histological parameters. At multivariate analysis, high titers of anti-C1q antibodies or of anti-dsDNA antibodies (P=0.005, OR = 8.67, CI: 2.03–37.3) were the independent predictors that discriminate proliferative from nonproliferative LN. All the immunological parameters, except anti-ribosome, showed a significant correlation with activity index but not with chronicity index. Only anti-C1q showed a significant correlation with the amount of proteinuria (R=0.2,P=0.03). None of the immunological parameters were predictive of remission at 6 and 12 months. We found that anti-C1q alone or in combination with anti-dsDNA emerged as the most reliable test in differentiating proliferative and nonproliferative LN. Anti-C1q was the only test correlated with the clinical presentation of LN. After treatment, the titre of the autoantibodies was significantly reduced, but none was predictive of remission.
