Clinical Outcomes of Patients With Primary Membranous Nephropathy and Subnephrotic Proteinuria

Objectives: To update the information about the prognosis of patients with primary membranous nephropathy (MN) and subnephrotic proteinuria and identify the relevant predictors.Methods: In total, 474 cases of biopsy-proven primary MN with at least 18 months of follow-up were reviewed to determine the outcomes of the subgroup of patients that presented with subnephrotic proteinuria. Clinical data included initial proteinuria and microhematuria, defined as the average proteinuria/microhematuria of the first 6 months during the course. Outcomes included partial remission (PR), complete remission (CR), nephrotic proteinuria progression, and kidney function progression, defined as ≥50% loss of kidney function or end-stage kidney disease.Results: In total, 205 patients with primary MN and subnephrotic proteinuria at biopsy were eligible. During a median follow-up of 43 months, 200 (97.56%), 167 (81.46%), and 53 (25.85%) patients attained PR, CR, and nephrotic proteinuria progression, respectively. Only one patient (0.49%) progressed to the kidney function progression. By multivariate Cox hazards regression analyses, the initial proteinuria was identified as the independent predictor for PR, CR, and nephrotic proteinuria progression with adjusted hazard ratios (aHRs) of 0.67 (95% confidence interval, 0.56–0.80), 0.50 (95% CI, 0.40–0.63), and 2.97 (95% CI, 2.23–3.97), respectively. A higher level of initial microhematuria was also associated with an increased risk of nephrotic proteinuria progression. The corresponding aHR was 1.11 (95% CI, 1.05–1.17).Conclusion: Among patients with primary MN and subnephrotic proteinuria, although the overall prognosis is excellent, dynamic detection and effective management of proteinuria remain important. In addition, initial microhematuria may be another predictor of nephrotic proteinuria progression.

Kidney Function Decline

Abstract Background ANGPTL8, an important regulator of lipid metabolism, was recently proven to have additional intracellular and receptor-mediated functions. This study aimed to investigate circulating levels of ANGPTL8 and its potential association with the risk of kidney function decline in a cohort study. Methods We analysed 2,311 participants aged 40 years old and older from the China Cardiometabolic Disease and Cancer Cohort (4C) Study. Kidney function decline was defined as an estimated glomerular filtration rate (eGFR) less than 60 mL per minute per 1.73 m2 of body surface area, a decrease in eGFR of ≥ 30% from baseline, chronic kidney disease (CKD)-related hospitalization or death, or end-stage renal disease. The association between baseline ANGPTL8 levels and kidney function decline was assessed using multivariable-adjusted Cox proportional hazards models, and inverse possibility of treatment weight (IPTW) was utilized to prevent overfitting. Results There were 136 (5.9%) cases of kidney function decline over a median of 3.8 years of follow-up. We found that serum ANGPTL8 levels at baseline were elevated in individuals with kidney function decline compared to those without kidney function decline during follow-up (718.42 ± 378.17 vs. 522.04 ± 283.07 pg/mL, p < 0.001). Compared with the first quartile, multivariable-adjusted hazard ratio (95% confidence intervals [CIs]) for kidney function decline was 2.59 (95% CI, 1.41–4.77) for the fourth ANGPTL8 quartile. Furthermore, compared with patients in the first ANGPTL8 quartile, those in the fourth ANGPTL8 quartile were more likely to report a higher stage of CKD (relative risk: 1.33; 95% CI, 1.01–1.74). The conclusions of the regression analyses were not altered in the IPTW models. Multivariable-adjusted restricted cubic spline analyses suggested a linear relationship of ANGPTL8 with kidney function decline (p for nonlinear trend = 0.66, p for linear trend < 0.001). Conclusions Participants with higher circulating ANGPTL8 levels were at increased risk for kidney function decline, highlighting the importance of future studies addressing the pathophysiological role of ANGPTL8 in CKD.

The aim of this study was to explore sex-specific associations between systolic blood pressure (SBP), hypertension, and the risk of incident atrial fibrillation (AF) subtypes, including paroxysmal, persistent, and permanent AF, in a general population. A total of 13,137 women and 11,667 men who participated in the fourth survey of the Tromsø Study (1994–1995) were followed up for incident AF until the end of 2016. Cox proportional hazards regression analysis was conducted using fractional polynomials for SBP to provide sex- and AF-subtype-specific hazard ratios (HRs) for SBP. An SBP of 120 mmHg was used as the reference. Models were adjusted for other cardiovascular risk factors. Over a mean follow-up of 17.6 ± 6.6 years, incident AF occurred in 914 (7.0%) women (501 with paroxysmal/persistent AF and 413 with permanent AF) and 1104 (9.5%) men (606 with paroxysmal/persistent AF and 498 with permanent AF). In women, an SBP of 180 mmHg was associated with an HR of 2.10 (95% confidence interval [CI] 1.60–2.76) for paroxysmal/persistent AF and an HR of 1.80 (95% CI 1.33–2.44) for permanent AF. In men, an SBP of 180 mmHg was associated with an HR of 1.90 (95% CI 1.46–2.46) for paroxysmal/persistent AF, while there was no association with the risk of permanent AF. In conclusion, increasing SBP was associated with an increased risk of both paroxysmal/persistent AF and permanent AF in women, but only paroxysmal/persistent AF in men. Our findings highlight the importance of sex-specific risk stratification and optimizing blood pressure management for the prevention of AF subtypes in clinical practice.

Lupus nephritis (LN) is a life-threatening manifestation of systemic lupus erythematosus (SLE) and is more common in children than adults. The epidemiology and management of childhood-onset SLE (cSLE) have changed over time, prompting the need to reassess expected outcomes. The purpose of this study is to use the Childhood Arthritis and Rheumatology Research Alliance (CARRA) prospective registry to validate historical principles of LN in a contemporary, real-world cohort. After an extensive literature review, six principles of LN in cSLE were identified. The CARRA registry was queried to evaluate these principles in determining the rate of LN in cSLE, median time from cSLE diagnosis to LN, short-term renal outcomes, and frequency of rituximab as an induction therapy. Of the 677 cSLE patients in the CARRA registry, 32% had documented LN. Decline in kidney function was more common in Black cSLE patients than non-Black patients ( p = 0.04). Black race was associated with worse short-term renal outcomes. In short-term follow up, most children with LN had unchanged or improved kidney function, and end stage kidney disease (ESKD) was rare. Ongoing follow-up of cSLE patients in the CARRA registry will be necessary to evaluate long-term outcomes to inform risk, management, and prognosis of LN in cSLE.

Introduction: Sepsis results in dysregulated inflammation, coagulation, and metabolism, which may contribute to increased cardiovascular disease (CVD) risk. We conducted a systematic review and meta-analysis to determine the association between sepsis and subsequent long-term CVD events. Methods: MEDLINE, Embase, and the Cochrane Controlled Trials Register and Database of Systematic Reviews were searched from inception to May 2020 to identify observational studies of adult sepsis survivors (defined by diagnostic codes or consensus definitions) measuring long-term CV outcomes. The primary outcome was a composite of myocardial infarction, CV death, and stroke. Random-effects models estimated the pooled cumulative incidence and adjusted hazard ratios of CV events relative to hospital or population controls. Odds ratios were included as risk ratios assuming <10% incidence in non-septic controls, and risk ratios were taken as hazard ratios (HR) assuming no censoring. Outcomes were analyzed at maximum follow-up (primary analysis) and stratified by time (<1 year, 1-2 years, and >2 years) since sepsis. Results: Of 11,235 abstracts screened, 25 studies (22 cohort studies, 2 case-crossover studies, and 1 case-control) involving 1,949,793 sepsis survivors were included. The pooled cumulative incidence of CVD events was 9% (95% CI; 5-14%). Sepsis was associated with an increased risk (HR 1.59, 95% CI 1.37-1.86) of CVD events at maximum follow-up ( Figure ); between-study heterogeneity was substantial (I 2 =97.3%). There was no significant difference when comparing studies using population and hospital controls. Significantly elevated risk was observed up to 5 years following sepsis. Conclusions: Sepsis survivors experience an approximately 50% increased risk of CVD events, which may persist for years following the index episode. These results highlight a potential unmet need for early cardiac risk stratification and optimization in sepsis survivors.

ABSTRACT Objective: To determine the incidence of sleep disorder at a follow-up examination from 1 to 4 years, in demented patients diagnosed at first visit, besides analyzing associated demographic and comorbidities characteristics. Methods: A total of 122 elderly patients aged 60 years or older and diagnosed with dementia (Alzheimer and other) were followed in a reference geriatric center for dementia. The clinical protocols included interviews with patient and caregiver, complete physical examination, laboratory and imaging tests. Criteria for the diagnosis of sleep disorder included complain of insomnia from the patient or caregiver using the Neuropsychiatric Inventory nighttime. Results: The incidence density of sleep disorder among dements was 18.7/100 person/years. The risk of developing sleep disorder within the frst and fourth years of follow-up was 9.8% and 50.9%, respectively. Multivariate Coxregression analysis revealed that educational level less than 8 years and report of aggressiveness at baseline were an independent predictor of sleep disorder, increased risk in 3.1 (95%CI: 1.30-9.22) and 2.1 times (95%CI: 1.16-4.17), respectively. Conclusion: The incidence of sleep disorder in demented patients was elevated, and was particularly associated to low educational level and aggressiveness at admission.

Evidence on the role of supper timing in the development of cardiovascular disease (CVD) is limited. In this study, we examined the associations between supper timing and risks of mortality from stroke, coronary heart disease (CHD), and total CVD. A total of 28,625 males and 43,213 females, aged 40 to 79 years, free from CVD and cancers at baseline were involved in this study. Participants were divided into three groups: the early supper group (before 8:00 p.m.), the irregular supper group (time irregular), and the late supper group (after 8:00 p.m.). Cox proportional hazards regression models were used to calculate hazard ratios (HRs) for stroke, CHD, and total CVD according to the supper time groups. During the 19-year follow-up, we identified 4706 deaths from total CVD. Compared with the early supper group, the multivariable HR of hemorrhagic stroke mortality for the irregular supper group was 1.44 (95% confidence interval [CI]: 1.05–1.97). There was no significant association between supper timing and the risk of mortality from other types of stroke, CHD, and CVD. We found that adopting an irregular supper timing compared with having dinner before 8:00 p.m. was associated with an increased risk of hemorrhagic stroke mortality.

Introduction: Carotid intima-media thickness (IMT) has been reported to predict kidney function decline. However, whether carotid IMT is associated with a hard kidney endpoint, end-stage renal disease (ESRD), has not been investigated. Hypothesis: We assessed the hypothesis that increased carotid IMT is associated with ESRD risk. Methods: We studied 13,197 ARIC participants at visit 1 (1987-1989) without history of cardiovascular disease including coronary heart disease, stroke and heart failure and assessed whether carotid IMT measured by B-mode ultrasound is associated with ESRD risk using Cox proportional-hazards models. Regarding carotid IMT parameters, we investigated the mean and maximum values of overall and segment-specific (common, bifurcation and internal carotid arteries) measurements. Results: Mean age was 54.0 (SD 5.7) years, and there were 3,373 (25.6%) blacks and 7,370 (55.8%) women. During a median follow-up of 22.7 years, 433 participants developed ESRD (1.4/1,000 person-years). After adjusting for shared risk factors for atherosclerosis and kidney disease, including baseline kidney function, carotid IMT was significantly associated with ESRD risk (hazard ratios between quartiles 4 and 1, 1.43 [95%CI: 1.01-2.04] for overall mean IMT and 1.73 [95%CI: 1.22-2.44] for overall maximum IMT). The associations were largely consistent in demographic and clinical subgroups. When we explored segment-specific IMTs, the associations with ESRD were most robust for bifurcation carotid. The adjusted hazard ratios between quartiles 4 and 1 were 1.48 (95%CI: 1.04-2.11) for mean bifurcation IMT and 1.42 (95%CI: 0.99-2.03) for maximum bifurcation IMT. Conclusions: Carotid IMT was independently associated with incident ESRD in the general population. Our findings suggest the shared etiology between atherosclerosis and ESRD and highlight the importance of monitoring kidney function over time in individuals with subclinical atherosclerosis.

Abstract Background and Aims Membranous nephropathy (MN) can be associated with tumor and present a paraneoplastic condition. Recently, development of tumors during the course of follow up is more in focus. It is especially interested whether patient with MN are prone to tumors, or tumors are condition indipendent of membranous nephropathy or consequence of imunosupressive therapy (IS). Method Retrospective data of all adult patients diagnosed with MN from 1987 to 2017 at the Department of Nephrology of University Hospital Centre Zagreb were analysed. Medical data regarding antropometric measeures and preexsisting comorbid disease at presentation and during follow up were derived from medical records and hospital informatic system. Furthermore, data regarding kidney function were used, namely serum creatinine (SCr), proteinuria. Renal function was assessed using CKD-EPI equation. CKD stages, partial and complete remission were defined according to KDIGO guidelines. Results From 1987 till 2017 a total of 122 patients were diagnosed with MN. Eighty nine (72.9%) were treated with imunosupressive therapy. Most commonly prescribed initial therapy was combination of corticosteroids and cyclophosphamide (N=66; 74%). Three (0,02%) patients had history of tumor with median of 3y (min – max 1-4 y) before glomerular disease presentation, two solid tumor, adenocarcinoma pulmonum and carcinoma prostatae, and one condition after allogenic haematopoetic transplantation due to acute myeloid leukemia. There was no difference in clinical presentation between those with positive history of malignant disease and others (proteinura 11.7 g/du (25-75C 3.4-15.7) vs. 5.8 g/dU (25-75C 3.4 – 8.5); p=0.232 and eGFR 57 ml/min/1,73m2 (25C-75C 14 – 59) vs. 81 ml/min/1.73m2 (25-75C 54 – 100); p=0.066). During follow up 11 (9%) patients developed tumor, median age of pts 67 y (min – max 59 – 71); nine solid tumors most comonly of gastrointestinal origin (pancreas, colon N=5 (45%)), then pulmonum (N=2(18%)) and urogenithal origin (ca renis and prostate N=2 18%). Also two hematological malignancies (B-ALL, B-NHL) occurred. Median time till confirmed malignant disease was 9 y (min – max 5 -24). At the time of detecting the tumor six (54%) patients were in complete and partial remission (4 and 2) and 2 (18%) patients had nephrotic syndrome. No difference was observed in proteinuria between those with malignant condition and other MN patients (1,4 g/dU (25 – 75C 0.2 – 5.6) vs. 0,29 g/dU (25 – 75C 0.13 – 0.74); P=0.154). MN patients with malignant disease during follow up had lower estimated glomerular filtration rate (eGFR 45 ml/min/1,73m2 (25 – 75C 22 – 70) vs. 77 (25 – 75C 58 – 92); p=0.010). There was no difference in cummulative dose of cyclophosphamide between those who developed tumor with others (24 g(25 – 75C13.5 – 30) vs. 27 g(25 – 75C 15 – 38)p=0.592). Conclusion Our data emphasize the need for long term follow up of patients with membranous nephropathy despite accomplishing remission of MN and period screening for malignant disease, especially in those with deteriorating kidney function.

AbstractPregnancy and pregnancy loss may be associated with increased risk of diabetes in later life. However, the evidence is inconsistent and sparse, especially among East Asians where reproductive patterns differ importantly from those in the West. We examined the associations of pregnancy and pregnancy loss (miscarriage, induced abortion, and still birth) with the risk of incident diabetes in later life among Chinese women. In 2004–2008, the nationwide China Kadoorie Biobank recruited 302 669 women aged 30–79 years from 10 (5 urban, 5 rural) diverse localities. During 9.2 years of follow-up, 7780 incident cases of diabetes were recorded among 273,383 women without prior diabetes and cardiovascular disease at baseline. Cox regression yielded multiple-adjusted hazard ratios (HRs) for the risk of diabetes associated with pregnancy and pregnancy loss. Overall, 99% of women had been pregnant, of whom 10%, 53%, and 6% reported having a history of miscarriage, induced abortion, and stillbirth, respectively. Among ever pregnant women, each additional pregnancy was associated with an adjusted HR of 1.04 (95% CI 1.03; 1.06) for diabetes. Compared with those without pregnancy loss, women with a history of pregnancy loss had an adjusted HR of 1.07 (1.02; 1.13) and the HRs increased with increasing number of pregnancy losses, irrespective of the number of livebirths; the adjusted HR was 1.03 (1.00; 1.05) for each additional pregnancy loss. The strength of the relationships differed marginally by type of pregnancy loss. Among Chinese women, a higher number of pregnancies and pregnancy losses were associated with a greater risk of diabetes.

Background Headache has not been established as a risk factor for dementia. The aim of this study was to determine whether any headache was associated with subsequent development of vascular dementia (VaD), Alzheimer’s disease (AD) or other types of dementia. Methods This prospective population-based cohort study used baseline data from the Nord-Trøndelag Health Study (HUNT 2) performed during 1995–1997 and, from the same Norwegian county, a register of cases diagnosed with dementia during 1997–2010. Participants aged ≥20 years who responded to headache questions in HUNT 2 were categorized (headache free; with any headache; with migraine; with nonmigrainous headache). Hazard ratios (HRs) for later inclusion in the dementia register were estimated using Cox regression analysis. Results Of 51,383 participants providing headache data in HUNT 2, 378 appeared in the dementia register during the follow-up period. Compared to those who were headache free, participants with any headache had increased risk of VaD ( n = 63) (multivariate-adjusted HR = 2.3, 95% CI 1.4–3.8, p = 0.002) and of mixed dementia (VaD and AD ( n = 52)) (adjusted HR = 2.0, 95% CI 1.1–3.5, p = 0.018). There was no association between any headache and later development of AD ( n = 180). Conclusion In this prospective population-based cohort study, any headache was a risk factor for development of VaD.
