Lupus nephritis (LN) is a serious complication of systemic lupus erythematosus (SLE). LN is a leading cause of morbidity and mortality in SLE patients. LN presents with various symptoms and signs, ranging from asymptomatic renal involvement to End-Stage Renal Failure (ESRD). The pathogenesis of LN is not clearly understood, however, there are extra and intra-renal underlying factors that have been postulated in LN pathogenesis. Renal biopsy is crucial to stage LN and to rule out other causes. Histopathological studies have shown six different types of LN. Knowing the histopathological lesion, chronicity and the disease activity are essential to plan the LN treatment and to predict the outcome. There are different regimens for treating LN. In this review, LN pathogenesis and new advances in treatment will be briefly reviewed.

It is uncommon for Systemic lupus erythematosus (SLE) to present with diffuse alveolar hemorrhage (DAH) as the initial presentation. To diagnose this in a young male with no renal involvement is further uncommon. We report a case of a 16-year-old boy, who presented with hemoptysis and was eventually diagnosed as DAH with underlying SLE. Treatment with steroids and immunosuppressant helped in rapid recovery from this potentially life-threatening condition. This case highlights the need of defining diagnostic criteria for SLE in patients presenting as DAH and formulating guidelines for treatment of the same, especially in absence of co-existing lupus nephritis.

Background Lupus nephritis is one of the most serious complications of systemic lupus erythematosus. This study evaluates the prevalence and correlation between neutrophil gelatinase-associated lipocalin and other biomarkers associated with renal involvement in systemic lupus erythematosus. Methods Paired serum and urine specimens from 50 suspected systemic lupus erythematosus patients, characterized by antinuclear antibodies detected by indirect immunofluorescence assay and varying positive concentrations of anti-double stranded DNA antibodies by Crithidia luciliae immunofluorescence assay, were investigated. Of these 50 patients, 18 were identified with renal involvement based upon laboratory serology. Patients and healthy control serum samples ( n = 50) were also evaluated for high avidity double stranded DNA IgG antibodies, anti-C1q IgG antibodies, and serum creatinine. The prevalence and relationship between biomarkers were evaluated using statistical methods. Results Serum and urine neutrophil gelatinase-associated lipocalin concentrations were significantly elevated in patients compared to controls, with a prevalence of 24% and 36%, respectively. These concentrations were also more markedly increased in systemic lupus erythematosus patients with renal involvement than those without. Spearman’s correlations between neutrophil gelatinase-associated lipocalin and other biomarkers tested ranged from 0.06 to 0.66 in all patients. Combined concordance as determined by Cronbach alpha coefficient between biomarkers was reduced from 0.71 to 0.58 (serum) and 0.62 (urine) when neutrophil gelatinase-associated lipocalin was removed. Conclusions Neutrophil gelatinase-associated lipocalin concentrations are elevated and demonstrate variable associated with other laboratory markers for renal involvement in systemic lupus erythematosus. Prospective longitudinal studies are needed to determine the optimal biomarker combinations for use in routine management of systemic lupus erythematosus patients at-risk for lupus nephritis.

Background: Lupus nephritis is defined as renal involvement in systemic lupus erythematosus (SLE) patients and the most important cause of morbidity and mortality. The diagnostic criteria that used to diagnose lupus nephritis are 1997 American Collegeof Rheumatology is 24 hours urine protein ≥500 mg and/or cellular cast, but significant renal damage can occur without proteinuria or cellular cast. Anti-C1q is an autoantibody that is produced by a chronic alteration of C1q collagen domain. Anti-C1q is a new specific marker for renal marker.Objective: To determine the validity of anti-C1q serum by using 1997 American College of Rheumatology criteria as a gold standard. Methods: This is a cross sectional study, conducted in October to December 2014 at Hasan Sadikin Hospital Bandung. The subjects had systemic lupus erythematosus with and without renal involvement, based on 1997 American College of Rheumatology criteria for SLE.Results: There were 65 subjects included in this study, 64 subjects were female and 1 subject was male. The age average was 32 (SD 11.7) years old. As many as 66.2% subjects had been diagnosed with lupus erythematosus systemic at least 3 years. Twenty four hours urine protein was measured using spectrophotometry, urine sediment was examinedfor cellular cast, and anti-C1q serum was measured using micro enzyme linked immunosorbent assay. Based on American College of Rheumatology criteria, 34 subjects were classified as lupus nephritis group while 31 subjects were classified as non-lupus nephritis group. The area under the curve of anti-C1q was 0.610. The cut-off value used in this study was 10.43 U/ml. The sensitivity, specificity, positive predictive value,negative predictive value and accuracy of anti-C1q assay were 41.18%, 77.42%, 66.67%, 54.55% and 58.46% respectively.Conclusion: Anti-C1q assay, based on this study, hasa low sensitivity and medium specificity to detect lupusnephritis

Propylthiouracil (PTU), used to treat Graves' disease, occasionally induces a lupus-like syndrome. A 39-year-old woman developed clinical manifestations of systemic lupus erythematosus with rash, serositis, myocarditis, and acute renal insufficiency, associated with serologies for lupus, after 3 wk of exposure to the drug. Renal biopsy revealed diffuse proliferative lupus nephritis. This article reviews the side effects of PTU and the literature on PTU-induced nephrotoxicity. Possible mechanisms and management of drug-induced lupus nephritis are also reviewed. To facilitate early and specific intervention, clinicians should be aware of the propensity of PTU to cause lupus-like syndromes with renal involvement.

Background Systemic lupus erythematosus is a heterogeneous chronic inflammatory autoimmune disorder characterized by an exacerbated expression of cytokines and chemokines in different tissues and organs. Renal involvement is a significant contributor to the morbidity and mortality of systemic lupus erythematosus, and its diagnosis is based on renal biopsy, an invasive procedure with a high risk of complications. Therefore, the development of alternative, non-invasive diagnostic tests for kidney disease in patients with systemic lupus erythematosus is a priority. Aim To evaluate the plasma levels of a panel of cytokines and chemokines using multiplex xMAP technology in a cohort of Colombian patients with active and inactive systemic lupus erythematosus, and to evaluate their potential as biomarkers of renal involvement. Results Plasma from 40 systemic lupus erythematosus non-nephritis patients and 80 lupus nephritis patients with different levels of renal involvement were analyzed for 39 cytokines using Luminex xMAP technology. Lupus nephritis patients had significantly increased plasma eotaxin, TNF-α, interleukin-17-α, interleukin-10, and interleukin-15 as compared to the systemic lupus erythematosus non-nephritis group. Macrophage-derived chemokine, growth regulated oncogene alpha, and epidermal growth factor were significantly elevated in systemic lupus erythematosus non-nephritis patients when compared to lupus nephritis individuals. Plasma eotaxin levels allowed a discrimination between systemic lupus erythematosus non-nephritis and lupus nephritis patients, for which we performed a receiver operating characteristic curve to confirm. We observed a correlation of eotaxin levels with active nephritis (Systemic Lupus Erythematosus Disease Activity Index). Our data indicate that circulating cytokines and chemokines could be considered good predictors of renal involvement in individuals with systemic lupus erythematosus.

Objective.To determine the frequency of International Society of Nephrology/Renal Pathology Society (ISN/RPS) class III or IV lupus nephritis in patients with systemic lupus erythematosus (SLE) without clinical renal involvement.Methods.We investigated the renal pathology of 195 patients with SLE, including 86 patients without clinical renal involvement.Results.Lupus nephritis other than class I was found in 58% of the patients without clinical renal involvement, and class III and IV nephritis was found in 15% of these patients. To reveal the predictive measures involved in class III or IV lupus nephritis, we explored the clinical measures in patients with SLE who did not have clinical renal involvement. Anti-dsDNA antibody titers were significantly higher (p = 0.0266) and C3 values were significantly lower (p = 0.0073) in patients with class III or IV lupus nephritis than in patients without class III or IV lupus nephritis. The sensitivity and specificity values were 77% and 73%, respectively, for cutoff levels of both 40 IU/ml for anti-dsDNA antibodies and 55 mg/dl for C3 (OR 8.8, p = 0.0011).Conclusion.The frequency of nephritis, including ISN/RPS class III and IV, was unexpectedly high in SLE patients without clinical renal involvement. ISN/RPS class III or IV lupus nephritis could be hidden in patients with SLE who present both a high titer of anti-dsDNA antibody and a low concentration of C3, even when they have clinically normal urinary findings and renal function.

ABSTRACT. In the course of the antiphospholipid syndrome (APS), the existence of vaso-occlusive lesions capable of affecting numerous organs is now well established. The renal involvement attributable to primary APS, APS nephropathy (APSN), corresponds to vaso-occlusive lesions of the intrarenal vessels, associating side-by-side, acute thromboses with chronic arterial and arteriolar lesions, leading to zones of cortical ischemic atrophy. A retrospective study of 114 lupus patients undergoing renal biopsy was undertaken to determine the following: (1) if APSN can be found in the course of systemic lupus erythematosus (SLE); (2) if certain clinical and biologic factors can permit the prediction of the presence of APSN; and (3) if APSN is a superadded renal morbidity factor in lupus patients. This study shows the following: (1) APSN occurs in SLE (32% of patients with renal biopsies) in addition to, and independently of, lupus nephritis; (2) APSN is statistically associated with lupus anticoagulant but not with anticardiolipin antibodies; (3) APSN is associated with extrarenal APS, mainly arterial thromboses and obstetrical fetal loss, but not with the venous thromboses of APS; (4) APSN is an independent risk factor, over and above lupus nephritis, that contributes to an elevated prevalence of hypertension, elevated serum creatinine, and increased interstitial fibrosis. Thus, it seems likely that, because of its associations with hypertension, elevated serum creatinine, and increased interstitial fibrosis, APSN may worsen the prognosis in these patients. APSN may also have therapeutic significance in that its recognition should permit a better balance between immunosuppressor and antithrombotic and/or vasoprotective therapy. Finally, this study suggests that APSN should be considered as an element to be included in the classification criteria of APS.

Objectives Systemic lupus erythematosus (SLE) is a chronic autoimmune multi-systemic disorder of the connective tissue, characterized mainly by involvement of the skin, joints, kidneys, and serosal membranes. It affects females particularly at childbearing age more commonly than males. Lupus nephritis affects around half of patients with SLE. Data about SLE and lupus nephritis in Saudi Arabia are still scarce. In this study, we aimed to evaluate the prevalence, clinical and laboratory findings of SLE and different histological types of lupus nephritis among Saudi patients at King Fahad Medical City. Methods This is a retrospective study for adult patients who have been evaluated at king Fahad medical city between 2014 and 2019 and fulfilled the Systemic Lupus International Collaborating Clinics classification criteria (SLICC). Results 112 patients, 103 (92%) females and 9 (8%) males, with confirmed diagnoses of SLE were reviewed. Skin rash (69.6%), photosensitivity (61.6%), mucosal ulcerations (45.9%), arthralgia and/or arthritis (44.6%) are the most common clinical features. Ninety seven (86.6%) out of 112 patients had a recorded first visit 24 hour urine protein level, out of those only 26 (23.2) patients presented with significant proteinuria of more than 0.5grams per day. Forty four (39.2%) have undergone kidney biopsy. Class IV and III lupus nephritis are the most common reported biopsy results (43.18% and 27.28% respectively). During the study period, three patients (2.7%) developed end-stage kidney disease requiring dialysis and five (4.5%) had renal transplant. Conclusion Our study provided insight on the demographics, characteristics and presentation of SLE patients and the outcome of lupus nephritis in Saudi Arabia.

Objectives. We aimed to evaluate the value of immunoglobulin (Ig) G, IgM, and IgA isotypes of anti-double-stranded DNA (anti-dsDNA) and anti-C1q antibody in diagnosing systemic lupus erythematosus (SLE) patients and elucidate their association with disease activity and lupus nephritis. Methods. Blood samples were obtained from 96 SLE patients, 62 other autoimmune disease patients, and 60 healthy blood donors. Anti-dsDNA IgG, IgM, and IgA isotypes and anti-C1q antibody were measured by enzyme-linked immunosorbent assay. Disease activity of SLE patients was assessed according to the SLE Disease Activity Index score. Results. When specificity was greater than 90%, the sensitivity of anti-dsDNA IgG, IgM, and IgA isotypes and anti-C1q antibody in diagnosing SLE was 75%, 45%, 33%, and 49%, respectively. The prevalence of anti-dsDNA IgG (p=0.002), anti-dsDNA IgA (p=0.028), and anti-C1q antibody (p=0.000) in active cases was significantly higher than those in inactive ones. In addition, the presence of anti-C1q antibody was associated with renal involvement (p=0.032). Anti-dsDNA IgM showed no significant association with disease activity, but it was inversely linked with lupus nephritis (p=0.005). When anti-dsDNA IgG and IgA and anti-C1q were combined to evaluate SLE disease activity, the specificity reached the highest level (90%). When anti-C1q positive was accompanied by anti-dsDNA IgM negative, the specificity of diagnosing lupus nephritis was up to 96%. Conclusions. This study demonstrated the role of anti-dsDNA IgG, IgM, and IgA isotypes and anti-C1q antibody alone or combination in diagnosing SLE. Anti-dsDNA IgG and IgA and anti-C1q were shown to be associated with disease activity, while anti-dsDNA IgM and anti-C1q were associated with lupus nephritis. When the related antibodies were combined, the diagnostic specificity was significantly higher.
