Abstract
Introduction: The classification of lupus nephritis (LN) on biopsy is essentially focused on morphologic changes in glomeruli. Renal vascular lesions are not addressed in detail in current classifications and are often overlooked. We aimed to determine the prevalence of vascular lesions in LN on biopsies and to compare these with biopsies not showing the vasculopathies. Methods: A total of 740 renal biopsies of LN were analysedfor presence of vasculopathies from January 2013 to June 2019. Of these, 527 (71.2%) biopsies showed vascular lesions (vascular group), which were further categorized into known five subtypes according to morphology and immunofluorescence (IF) findings. Remaining 213 (28.8%) biopsies constituted non-vascular group. Clinical, demographic and laboratory parameters were compared between these two groups. Results: The mean age was 27.95 ± 9.8 years and 27.0 ± 9.4 years in the vascular and non-vascular groups respectively with higher M:F (1:2 > 1:7) in vascular group. Majority of vasculopathies (257, 48.7%) were found in biopsies with class IV LN. Haematuria (69.8% vs. 20.1%), proteinuria (100% vs. 62%), anemia (48.3% vs. 3.60%) and hypertension (39.8% vs. 8.46%) were common in group I. Uncomplicated vascular immune deposits (426; 80.8%) were the most common vasculopathy and true vasculitis (4;0.8%) was least common. Activity and chronicity indices (7.35 ± 3 and 2.45 ± 1.5, respectively) were significantly higher in the vascular group. Activity index was highest in uncomplicated vascular immune deposits (7.45 ± 2.8) and chronicity index was highest in non-specific sclerotic vascular lesions (2.7 ± 1.6). Conclusion: Vascular involvement is common in LN. Uncomplicated vascular immune deposits were common vasculopathies whereas true vasculitis was least common. The morphology and IF both need to be carefully screened for the diagnosis of vasculopathies.

Abstract
Chemotherapy-induced cardiac derangement is a major concern in health sector. Cyclophosphamide as a chemotherapeutic agent induces acute cardiotoxicity through its toxic metabolite, acrolein. This study evaluated the effect of ethanol extract of turmeric on cyclophosphamide-induced acute cardiotoxicity in Wistar rats. Thirty-five healthy Wistar rats, weighing 200-250g were randomly assigned into 7 groups (Groups A, B, C, D, E, F and G) N=5. Group A was the control, group B was negative control, and group C was administered 200mg/kg of turmeric extract (orally) only. While groups B, D, E, F and G were all administered 100mg/kg cyclophosphamide (i.p) for 10 days. Groups D and E were administered 100mg/kg and 200mg/kg of turmeric extract (orally) respectively for 72 hours before cyclophosphamide administration. Groups F and G were concomitantly administered 100mg/kg cyclophosphamide (i.p) with doses of 100mg/kg and 200mg/kg of turmeric extract (orally) respectively. The rats were sacrificed under ketamine anesthesia (30mg/kg i.m). The left ventricle of the heart was excised. One-way ANOVA was used to analyze data. Results revealed that there was statistically significant (P<0.05) difference in body weight change, CK-MB, and LDH across all experimental groups; which were significantly lower in cyclophosphamide group. Histology and Immunohistochemistry revealed that there were morphological alterations in the myocardium of the left ventricle in group B while turmeric extract ameliorated cyclophosphamide-induced damage in the myocardium in other experimental groups. In conclusion, cyclophosphamide-induced myocardial alterations were significantly ameliorated through administration of ethanol extract of turmeric.

Abstract
Noninflammatory necrotizing vasculopathy, also referred to as lupus vasculopathy, is not infrequently observed in the pathology of lupus nephritis. It affects vessels causing them to become severely narrowed and occluded by a mechanism involving immune complexes. We experienced a 51-year-old woman with lupus nephritis class IV + V, which was accompanied by lupus vasculopathy. Renal biopsy and light microscopy showed eosinophilic hyaline-like material in the afferent and/or efferent arterioles, which narrowed the lumen, and which were positive for IgG by immunofluorescent analysis. Electron microscopy indicated that amorphous material and endothelial detachment occluded the arterioles. These findings were consistent with those of lupus vasculopathy. We treated the patient with steroids and cyclophosphamide. By the day of discharge, her levels of creatinine and proteinuria had undergone partial remission. Although lupus vasculopathy was implied as a lesion with unfavorable renal prognosis, some recent reports suggest its true renal prognosis is not unfavorable necessarily. Nevertheless, lupus vasculopathy is an important finding in diagnosis in contradiction to other vascular legions in systemic lupus erythematosus. In addition, a standard therapy has also not been established. Therefore, it is important to accumulate cases of lupus vasculopathy to determine its prognosis and develop standard treatments.

Complement-mediated thrombotic microangiopathy associated with lupus nephritis. Blood Adv 2019; 2:2090-2094.

Abstract
Complement-mediated thrombotic microangiopathy (CM-TMA) is a clinical disorder driven by the generation of excess complement. It is characterized by thrombocytopenia and microangiopathic hemolytic anemia (MAHA) with microvascular thrombosis resulting in systemic organ damage (TMA). One form of CM-TMA, atypical hemolytic uremic syndrome (aHUS), is characterized by pathologic complement activation due to the loss of the natural regulators of the complement system, which results in systemic endothelial and organ damage. Lupus erythematosus is a multisystem immune complex disorder associated with activation of complement, as well as renal failure termed lupus nephritis (LN). A subset of these patients also develop TMA, with progressive life-threatening thrombocytopenia, MAHA, and progressive renal failure similar to aHUS. This subset of patients is poorly responsive to corticosteroids, cyclophosphamide, immunomodulation, and plasma exchange. In this article, we report 11 cases of LN associated with TMA progressing through these therapies, 10 of which were successfully treated with complement inhibition. Complement-regulatory protein mutations, including complement factor H (CFH), factor I, factor B, membrane cofactor/(CD46) and thrombomodulin, and CFH-related 1-3, were identified in 6 of 10 patients tested. One patient had a loss of a renal allograft. Three patients had concurrent antiphospholipid syndrome. Two of the 3 patients had normal D-dimers at this presentation. We believe that this subset of lupus patients, with clinical and pathologic manifestations of aHUS, define a separate entity that we believe should be termed CM-TMA associated with LN.

Abstract
Objectives The aim of this study was to investigate plasma ADAMTS-13 activity in patients with proliferative lupus nephritis and to evaluate the role of clinical, laboratory and pathological features, especially the vascular lesions in lupus nephritis. Methods Plasma samples from 163 class III and IV lupus nephritis patients confirmed by biopsy examinations and 98 normal controls were collected. ADAMTS-13 activity was evaluated by a residual collagen binding assay. IgG autoantibodies against ADAMTS-13 were detected by ELISA using recombinant ADAMTS-13 as a solid-phase ligand. Levels of vWF were measured by ELISA. Their associations with clinical, laboratory and pathological features were further assessed. Results Plasma ADAMTS-13 activity in lupus nephritis patients was significantly lower than that in normal controls (84 ± 21% vs. 90 ± 13%, p = 0.005). IgG ADAMTS-13 autoantibodies were detected in only three patients. The plasma level of vWF was significantly higher in the lupus nephritis group than in normal controls (1.00 ± 0.79 vs. 0.70 ± 0.30, p = 0.025). Plasma ADAMTS-13 activity was negatively correlated with the level of serum creatinine and proteinuria ( r = –0.354, p < 0.001; r = –0.200, p = 0.011, respectively). Patients with a higher level of ADAMTS-13 activity had significantly higher levels of factor H (401.51 ± 183.01 µg/ml vs. 239.02 ± 155.45 µg/ml, p = 0.005). Plasma ADAMTS-13 activity was negatively associated with total pathological AI scores ( r = –0.326, p < 0.001), endocapillary hypercellularity ( r = –0.419, p < 0.001), cellular crescents ( r = –0.274, p < 0.001), subendothelial hyaline deposits ( r = –0.266, p = 0.001), interstitial inflammatory cell infiltration ( r = –0.304, P < 0.001), tubular atrophy ( r = –0.199, p = 0.011), acute glomerular vascular lesions ( r = –0.344, p < 0.001) and acute renal vascular lesions ( r = –0.338, p < 0.001). No association was found between level of vWF and plasma ADAMTS-13 activity ( r = 0.033, p = 0.671). Low level of ADAMTS-13 activity was a risk factor for renal outcomes ( p = 0.039, HR = 0.047, 95% CI: 0.120–1.005). Conclusions Decreased ADAMTS-13 activity was found in patients with proliferative lupus nephritis, and plasma ADAMTS-13 activity was closely associated with renal injury indices, especially pathological vascular scores. The role of ADAMTS-13 in the disease remains to be further investigated.

Abstract
Systemic lupus erythematosus (SLE) is associated with a broad spectrum of clinical and immunologic manifestations, of which lupus nephritis is the most common cause of morbidity and mortality. The development of nephritis in patients with SLE involves multiple pathogenic pathways including aberrant apoptosis, autoantibody production, immune complex deposition and complement activation. The 2003 International Society of Nephrology/Renal Pathology Society (ISN/RPS) classification system for lupus nephritis was widely accepted with high intraobserver and interobserver concordance to guide therapeutic strategy and provide prognostic information. However, this classification system is not based on the underlying disease pathophysiology. Some additional lesions that contribute to disease presentation, including glomerular crescents, podocyte injury, tubulointerstitial lesions and vascular injury, should be recognized. Although outcomes for patients with lupus nephritis have improved over the past 30 years, treatment of this disease remains challenging and is best approached on the basis of the underlying pathogenesis, which is only partially represented by the various pathological phenotypes defined by the ISN/RPS classification. Here, we discuss the heterogeneous mechanisms involved in the pathogenesis of lupus nephritis and how improved understanding of underlying disease mechanisms might help guide therapeutic strategies.

Abstract
We performed a retrospective cohort analysis to define the prognostic significance of vascular lesions documented in renal biopsies of lupus nephritis patients. A total of 429 patients were segregated into five groups: (1) no vascular lesions (NVL), (2) arterial sclerosis (AS), (3) non-inflammatory necrotizing vasculitis (NNV), (4) thrombotic microangiopathy (TMA), and (5) true renal vasculitis (TRV). Renal outcomes were analyzed by Cox regression models, and correlations between vascular lesions and activity/chronicity scores were determined by Spearman's coefficients. A total of 200 (46.6%) had NVL, 189 (44.0%) AS, six NNV (1.4%), 23 (5.4%) TMA, and 11 (2.6%) TRV. Patients with NVL were younger, with higher renal function; patients with TMA and TRV had lower renal function and higher arterial pressure at baseline. Antiphospholipid syndrome and positive lupus anticoagulant were more frequently observed in the TMA group. Five-year renal survival was 83% for NVL, 63% for AS, 67% for NNV, 31% for TMA, and 33% for TRV. NNV and TRV were significantly correlated with activity scores, while AS and chronic TMA were correlated with chronicity scores. Renal vascular lesions are associated with renal outcomes but do not behave as independent factors. The addition of vascular lesions to currently used scores should be further explored.

Abstract
Cyclophosphamide is an alkylating agent widely used for the treatment of malignant neoplasia and which can be used in the treatment of multiple rheumatic diseases. Medication administration errors may lead to its reduced efficacy or increased drug toxicity. Many errors occur in the administration of injectable drugs. The present study aimed at structuring a routine for cyclophosphamide use, as well as creating a document with pharmacotherapeutic guidelines for the patient. The routine is schematized in three phases: pre-chemotherapy, administration of cyclophosphamide, and post-chemotherapy, taking into account the drugs to be administered before and after cyclophosphamide in order to prevent adverse effects, including nausea and hemorrhagic cystitis. Adverse reactions can alter laboratory tests; thus, this routine included clinical management for changes in white blood cells, platelets, neutrophils, and sodium, including cyclophosphamide dose adjustment in the case of kidney disease. Cyclophosphamide is responsible for other rare - but serious - side effects, for instance, hepatotoxicity, severe hyponatremia and heart failure. Other adverse reactions include hair loss, amenorrhea and menopause. In this routine, we also entered guidelines to post-chemotherapy patients. The compatibility of injectable drugs with the vehicle used has been described, as well as stability and infusion times. The routine aimed at the rational use of cyclophosphamide, with prevention of adverse events and relapse episodes, factors that may burden the health care system.
