We employed inpatient and outpatient billing data from Medicaid patients at Brigham and Women's Hospital in Boston to identify lupus nephritis cases. We identified Medicaid patients seen 2000-2007 with > 2 claims for lupus (ICD9 710.0) and compared four separate ICD9-based strategies: 1: greater than 2 claims for any combination of acute or chronic glomerulonephritis (including lupus glomerulonephritis), acute or chronic renal failure, nephritis or nephrotic syndrome (including lupus nephrotic syndrome), renal failure or proteinuria (ICD-9 codes 580.-586. and 791.0), 2: greater than 2 claims for visit to a nephrologist, 3: either strategy 1 or strategy 2 and 4: both strategy 1 and strategy 2.
Independently and blinded to these results, two board-certified rheumatologists performed medical record reviews to validate lupus and lupus nephritis according to American College of Rheumatology Criteria for Systemic Lupus Erythematosus14 (link), 15 (link). To validate the presence of lupus nephritis, we employed the ACR criteria14 (link), 15 (link) referring to the presence of nephritis (persistent proteinuria > 0.5 gms/day, or > 3+ on urinalysis, or cellular casts), AND/OR biopsy-proven renal disease attributed to lupus and classified as Class-III-IV or V (focal or diffuse glomerulonephritis or membranous nephropathy) according to the World Health Organization classification16 (link) for subjects identified by each algorithm. We calculated the positive predictive value (PPV) for each strategy. PPV is calculated as the number with confirmed lupus nephritis divided by the total number subjects within that strategy.

Using a methodological approach based on measurement science the criteria were developed in four phases (10 (link)): 1) criteria generation, 2) criteria reduction, 3) criteria definition and weighting and 4) refinement and validation (Figure 1). The whole initiative was overseen by a 12-member steering committee (MA, KHC, DD, MM, RR-G, JSS, DW, DB, DK, DJ, TD and SRJ) nominated by EULAR and the ACR in equal numbers, based on SLE and/or methodological experience and previous involvement in international projects.
The current project, jointly supported by the European League Against Rheumatism (EULAR) and the ACR, was originally based on two key concepts. One, we hypothesized that the presence of ANA would be better employed as an entry criterion than as a classification criterion (10 (link)). Such an approach was thought to reflect underlying SLE pathogenesis, and take into account ANA test characteristics of high sensitivity and limited specificity. Two, we expected individual criteria would not be of equal utility (weight) for the classification of SLE (11 (link)), for example mucosal ulcers vs. biopsy-proven lupus nephritis. Accordingly, the validity of using positive ANA as an entry criterion was explicitly addressed in phase 1 of the current activity (12 (link)). Likewise, methodologic strategies to develop weighted criteria were used.

For the purpose of these recommendations, lupus nephritis is defined as clinical and laboratory manifestations that meet ACR criteria (persistent proteinuria > 0.5 g per day or greater than 3+ by dipstick, and/or cellular casts including red cell, hemoglobin, granular, tubular or mixed) [12 (link)]. A review of the ACR criteria has recommended that a spot urine creatinine/protein ratio >0.5 can be substituted for the 24 hour protein measurement, and “active urinary sediment” (>5 RBC/hpf, >5 WBC/hpf in the absence of infection, or cellular casts limited to RBC or WBC casts) can be substituted for cellular casts [1 (link)]. An additional, perhaps optimal, criterion is a renal biopsy demonstrating immune complex-mediated glomerulonephritis compatible with lupus nephritis [1 (link)]. Finally, for the purpose of implementing these recommendations, the Core Executive Panel felt that a diagnosis of lupus nephritis should also be considered valid if based on the opinion of a rheumatologist or nephrologist.

We defined individuals with SLE as having ≥ 3 International Classification of Diseases, ninth revision (ICD-9) codes for SLE (710.0), each at least 30 days apart, from hospital discharge diagnoses or physician visit claims. We required three billing codes to eliminate “rule-out” SLE cases. Among individuals with SLE, we identified those with lupus nephritis (LN), defined as having ≥ 2 ICD-9 hospital discharge diagnoses or physician billing claims for nephritis, proteinuria and/or renal failure, on or after the SLE diagnosis, and at least 30 days apart. This algorithm has been demonstrated to have a positive predictive value of 80 percent for the identification of adults with LN in a Medicaid population (20 (link)). We also performed a sensitivity analysis for LN that used >2 SLE claims with the aforementioned >2 LN-related claims.

The evidence base for the SRI evaluation came from a phase II dose-ranging RCT evaluating the safety, tolerability, biologic activity, and efficacy of belimumab combined with SOC in 449 SLE patients who had SELENA-SLEDAI scores of ≥4 at baseline (32 ). Patients with a diagnosis of SLE by ACR criteria (37 (link)) and a history of measurable autoantibodies who were on a stable SOC regimen (2 (link)) for at least 30 days prior to screening were included; patients with active lupus nephritis or central nervous system disease were excluded. Concurrent corticosteroid and immunosuppressive agents could be changed throughout the protocol as clinically indicated. All patients gave informed consent for the study, and there was an independent Data Safety Monitoring Committee (32 ).

Example 11

The autoantibody profiles of SLE patients with lupus nephritis were compared with those of SLE patients without lupus nephritis. Following univariate statistical evaluation, a threshold value of p<0.05 and a 1.5 times modified reactivity compared with the control group were applied. 85 antigens met these criteria and are detailed in Table 2.

FIG. 7 shows the volcano plot of the sera compared with selected lupus nephritis antigens.

Group 2 in Table 2 contains 30 additional and important antigens which can be used for the generation of lupus nephritis biomarker panels.

An L1-penalised logistic regression model with five-fold cross validation and twenty times repetition was computed for the selection of the best candidates. The antigens selected most frequently in this model computation with a frequency of more than 50% constituted the best candidates for the diagnosis of lupus nephritis.

FIG. 8 shows the frequency distribution of the lupus nephritis antigens.

Group 5 comprises further statistically significant antigens suitable for the diagnosis of lupus nephritis.

From January 2015 to August 2019 we prospectively recruited patients attending the peripheral nerve clinic in the John Radcliffe Hospital (Oxford, UK) with either confirmed or suspected inflammatory neuropathy to an observational study (Research Ethics Committee approval number 14/SC/0280). These patients provided informed written consent. Serum samples from these patients, and patients with suspected inflammatory neuropathies, received by our laboratory for diagnostic testing between August 2017 and August 2019. were screened for antibodies against paranodal (CNTN1, contactin-associated protein 1—Caspr1, neurofascin 155—NF155) and nodal (NF140/186) antigens.
To investigate whether CNTN1 antibodies might be more widely associated with nephrotic syndrome caused by idiopathic MGN itself, we examined 295 serum samples from patients with idiopathic membranous nephropathy, collected as part of the MRC Glomerulonephritis bank [14 (link)].
Serum samples from 70 patients with other antibody-mediated CNS neurological disorders, 20 with multiple sclerosis, 120 individuals without neurological disease, and 46 patients with lupus nephritis, including pure class V membranous lupus nephritis, were also obtained as controls (S1 Fig).
Information that could identify individual participants was stored confidentially and only accessible at the time of data collection to treating physicians, or those with necessary ethical approval and Good Clinical Practice (GCP) training. Data was subsequently de-identified.

More about "Lupus Nephritis"

Lupus Nephritis is an autoimmune disorder characterized by inflammation of the kidneys, often associated with systemic lupus erythematosus (SLE).
It can lead to serious complications if not properly managed.
Lupus nephritis is a subtype of glomerulonephritis, a group of kidney diseases that affect the glomeruli, the filtration units of the kidneys.
Symptoms of lupus nephritis may include proteinuria, hematuria, hypertension, and edema.
Diagnosis typically involves kidney biopsy, which can determine the severity and class of the disease.
Treatment often includes immunosuppressant medications, such as corticosteroids, mycophenolate mofetil, or cyclophosphamide, to control inflammation and prevent further kidney damage.
Researchers studying lupus nephritis may utilize various techniques and tools, such as the ECL assay for measuring autoantibody levels, the AU5421 biochemistry analyzer for lab tests, the XC-408 ESR Monitor for erythrocyte sedimentation rate, and Rabbit anti-OXR1 and Anti-GPX1 antibodies for oxidative stress markers.
Anti-CD74 polyclonal antibodies can be used to assess immune cell activation, while RIPA buffer and FITC-labeled goat anti-mouse IgG facilitate protein extraction and visualization, respectively.
The LSM 510 confocal laser scanning microscope can be employed for high-resolution imaging of kidney tissue, and the WithDeadEnd™ Colorimetric Apoptosis Detection System can be used to detect and quantify apoptosis, or programmed cell death, in the kidneys.
By leveraging these tools and techniques, researchers can gain a deeper understanding of the underlying mechanisms of lupus nephritis, identify potential biomarkers, and develop more effective treatments to improve the quality of life for patients suffering from this complex and debilitating condition.
