ABSTRACTObjective: Lupus nephritis (LN) is the most common and serious manifestation of systemic lupus erythematosus (SLE) and an important cause ofmorbidity and mortality. Although diagnosis of LN is straight forward in a patient with SLE and proteinuria, and active urine sediment and perhapsrenal insufficiency, still renal biopsies are required at diagnosis to enable classification of nephritis severity, to provide prognostic information, and toguide treatment. Hence, the objective of this study is to determine the frequency of distribution of different classes of LN based on renal biopsy reportsand to correlate it with various laboratory findings.Methods: Retrospective study was done in all patients with LN who had at least one representative renal biopsy and evaluated in NephrologyDepartment of SCB Medical College, Cuttack, in 6-month duration. Various laboratory values were recorded and correlated with histopathologicallupus classifications.Results: Out of 35 patients enrolled, 33 (94.28%) were females and 2 (5.71%) were males. Mean age was 27.53±12.26 years. Majority of cases belongto Class IV followed by Class V. Patients of Class IV LN have a significantly low hemoglobin level. Similarly, serum urea and creatinine are higher inGroup IV than other groups, and serum creatinine was found to be significant. 24 hrs urinary protein excretion has a significant correlation with theclasses of LN.Conclusion: This study suggests some meaningful correlation between laboratory findings and histopathological lupus classification. This study alsosuggests that renal biopsies are still beneficial for better evaluation of renal status and determination of LN classes.Keywords: Clinico-pathological correlation, Lupus nephritis, Biopsy.

Clinical features of Systemic Lupus Erythematosus (SLE) worsens when it involves kidneys. Even then in our socioeconomic context the patients who seek admission are usually at later stages. Moreover histological classes may not be previewed by clinical and laboratory features. The aim of the study is to show variation of clinical features and laboratory findings in relation to pathological classes of Lupus nephritis. It was a cross sectional descriptive study enrolling 30 female patients admitted in medicine and nephrology department of Chittagong Medical College. Majority of the patients are of age range 21-40 years (73%); belonging to middle class family (90%) and educated upto level of secondary school certificate (43%). Oedema (93%), normotension (73%) and anaemia (93%) are common clinical features. Though all patients had macroscopic proteinuria only 20 % patients had massive proteinuria (>3gm%). Serologically Nineteen patients are ANA positive (63%) and all patients had Anti-dsDNA positivity. Class III and Class IV comprises 70% of patients. Estimated Glomerular filtration rate (eGFR) is more in class V ( mean 77.77) and class III (mean 76.86) than class II ( mean 52.67) and class IV ( mean 59.95) signifying eGFR cannot estimate severity. In conclusion without renal biopsy Lupus nephritis class cannot be ascertained and so class specific management cannot be given. JCMCTA 2012 ; 23 (2): 34-37

Abstract INTRODUCTION: Lupus nephritis (LN) is a major complication of systemic lupus erythematosus (SLE). Renal involvement is a major determinant of the prognosis of SLE. The histological classification of LN is a key factor in determining the renal survival of patients with LN. Prompt recognition and treatment of renal disease are important, as early response to therapy is correlated with better outcome and renal biopsy plays an important role in achieving this. OBJECTIVES: The objective of this study was to correlate the clinical and laboratory findings with histopathological classes of LN as per the 2003 International Society of Nephrology-Renal Pathology Society (ISN/RPS) classification system. PATIENTS AND METHODS: Fifty-six patients with SLE, undergoing a renal biopsy for renal dysfunction were studied. The comparison of data from multiple groups was made by Pearson’s Chi-square test and between two groups by independent samples t-test. The values of P < 0.05 were considered statistically significant. RESULTS: Of the 56 cases studied, 51 (91.1%) were females. The most common presenting symptoms were edema, arthralgia, and hypertension. Class IV (55.4%) was the most common class. Thirty-nine (69.6%) cases showed full house immunostaining. Hypertension, hematuria, proteinuria, and tu bulo-interstitial disease showed a significant correlation (P < 0.05) with ISN/RPS classification, 2003. CONCLUSION: Assessment and management of patients with suspected LN are greatly facilitated through information obtained by renal biopsy. Since renal morphology may predict long-term prognosis, and no clinical or laboratory feature uniformly predicts prognosis, it is important to study the constellation of features in LN for better patient management.

Abstract Aim: TO assess the effects of rituximab (RTM) therapy on clinical and morphologic activity of lupus nephritis (LN). Material and methods: The study included 45 patients with confirmed diagnosis of systemic lupus erythematosus (SLE), unaffected by previously received standard therapy with glucocorticoids (GCs) and cytostatics. The disease activity was assessed using Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI 2K); to assess the LN activity we used the SLICC RA/RE index. Forty-five patients with LN were given puncture renal biopsy prior to prescribing RTM; 16 patients had repeated renal biopsy 1 year and more after beginning the anti-B-cell therapy. LN was graded histologically in accordance with the WHO classification (2003) with indices of activity (AI) and chronicity (CI). Results: The predominant number of patients had class III - IV of LN. The repeated renal biopsies demonstrated that LN had undergone a transition into a more favourable morphologic class, which was associated, in most of these cases, with a positive therapeutic effect. The follow-up dynamics showed a statistically significant reduction of AI (p=0.006), and no statistically significant changes in the CI (p = 0.14). Conclusion: The long-term follow-up in the study has showed that repeated courses of anti-B-cell therapy with RTM have a positive effect both on SLE activity and generally on the renal process. The reduction of the morphologic class of LN as assessed in the repeated renal biopsies is a convincing proof for this. Eleven out of 16 patients experienced transition of the morphologic class into a more favourable type, which in most cases was combined with lower AI (p = 0.006). We found no evidence of increase in the CI (p = 0.14).

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease that may affect any organ of the body. Lupus nephritis (LN) is a frequent and serious complication of SLE. We report a case of an 80-year-old woman who was initially diagnosed with late-onset SLE and eventually developed LN in the setting of normal complements, double-stranded DNA, C-reactive protein, erythrocyte sedimentation rate, and urine sediment. She developed abnormal renal function (creatinine of 1.7 mg/dl) and mild proteinuria (1-2+) without hematuria. Renal biopsy showed class IV lupus glomerulonephritis, active and chronic. The patient was started on mycophenolate mofetil which led to improvement of proteinuria and stabilization of creatinine. The suspicion for LN in a patient with late-onset SLE should remain high when there is development of suspicious renal or urinary abnormalities even if laboratory values do not suggest high disease activity and urinary sediment is normal. To our knowledge, this is one of the oldest patients with biopsy-proven LN and late-onset SLE.

Objective: To identify the clinical factors associated with renal response and flare in lupus nephritis (LN). Methods: All 115 patients with biopsy-proven LN diagnosed between January 2002 and June 2015 in a tertiary centre comprised of an inception cohort that was followed up until February 2017. Baseline demographic, clinical parameters, renal biopsy histology, induction and maintenance immunosuppressive therapies, complete renal response (CRR), creatinine doubling, end-stage renal disease (ESRD), renal flares and infections were retrieved and analyzed with univariate log-rank test and multivariate Cox regression. Results: At the time of the first renal biopsy, the age of patients was 38 ± 12.2 years (mean ± standard deviation), 90% female and systemic lupus erythematosus (SLE) disease duration 46 months (median); 67.0% were LN class IV or class IV + V. Patients were followed up for 104 ±49 months after biopsy. At months 3, 6, 12 and 24, a cumulative 25%, 46%, 66% and 76% of patients had achieved CRR, respectively. However, 49.5% who had CRR experienced [Formula: see text]1 infection of renal flare, with cumulative risk of 5%, 17%, 25% and 43% at year 1, 2, 3 and 5, respectively. Multivariate analysis showed that nephrotic syndrome ([Formula: see text] = 0.03) and delay of renal biopsy [Formula: see text]2 months from the onset of LN ([Formula: see text] ¡ 0.01) were negatively associated with CRR. Hydroxychloroquine use was beneficial in attaining CRR ([Formula: see text] = 0.03, hazard ratio = 1.70, 95% CI: 1.04, 2.80) and preventing renal flare ([Formula: see text] = 0.01, odds ratio = 0.51, 95% CI: 0.29, 0.88). By the end of the study, 80% of patients remained in CRR though 10.4% patients ended up in ESRD (all class IV), 8.7% died and 28.7% had [Formula: see text]1 infection episode requiring hospitalization. Conclusion: Most LN patients could achieve CRR after immunosuppressive therapy but renal flares were common over time. Infective complications were fairly frequent but the incidence of ESRD was low. The use of hydroxychloroquine was associated with better renal response and fewer flares.

Introduction: Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect multiple organs. When the kidney is involved it is generally termed lupus nephritis (LN), and is a major contributor to the morbidity and mortality associated with SLE. The classic pattern of lupus nephritis in a renal biopsy is an immune complex mediated glomerulonephritis. The presence of crescents, in diffuse proliferative lupus nephritis, and serologic positivity for antineutrophil cytoplasmatic antibodies (ANCA), more often antimyeloperoxidase than anti-proteinase 3, has been linked with specific clinicopathological features, poor treatment response and a worse kidney survival. Clinical case: We present the case of a 19-year-old male, without relevant past medical history, who presented severe headaches, hypertension and peripheral edema. The blood analysis revealed hemoglobin (Hb) 7.6 g/dL, creatinine (Cr) 2.64 mg/dL, blood urea nitrogen (BUN) 101 mg/dL, and urine analysis, hematuria and nephrotic proteinuria. The autoimmunity panel results were consistent with SLE paired with positivity for ANCA-proteinase 3 antibody. A renal biopsy revealed crescentic glomerulonephritis with fibrinoid necrosis and Bowman capsule rupture. The patient was diagnosed with class IV LN. The initiation treatment consisted of cyclophosphamide (CIPH) and prednisolone (PDN). At the 6-month follow-up, CIPH was stopped and mycophenolate mofetil (MMF) initiated as maintenance therapy, combined with PDN. Although microscopic hematuria and C3 consumption were still present (a new biopsy was pondered but the patient refused any further invasive diagnostic measures), C1q levels decreased from 26.6 to 19.3 U/ml (negative if < 20 U/ml) and anti-dsDNA was also negative with progressive declination of the degree of proteinuria. The creatinine levels returned to normal. Conclusion: The authors emphasize the importance of this class IV LN, influenced by the association with anti-proteinase 3, due to the implications in the histopathological pattern and in therapy selection. In this specific case kidney function, proteinuria and lupus activity had an important decrease without significant complications with the chosen treatment.

AbstractAim. The prevalence ratio of systemic lupus erythematosus in men compared to women is 1:10, with more aggressive forms in men and in children. The incidence of lupus nephritis is of 50-60% in patients with lupus.In this paper, we aim to report on a series of cases that include male patients who had lupus nephritis via renal biopsy and were admitted between January 2011 - December 2017, with or without other SLE manifestations. The aim is to review the particularities and the therapeutic response: age at onset, disease duration, lupus nephritis class, extra-renal organ involvement of lupus disease, paraclinical findings – proteinuria, inflammatory syndrome, renal function, therapeutic response – immunosuppressive regimens used for induction and maintenance, remission onset, remission type, number of flares, side effects of immunosuppressive therapy.Materials and method. We have reviewed the histopathology database of male patients with lupus nephritis revealed via renal biopsy, medical charts and the Hippocrates information system in order to collect patient data.Outcomes. Out of 68 renal biopsies positive for lupus nephritis, 9 were from male patients, which reveals a 6.5:1 ratio. The average age at the time of the renal biopsy is 37. 33 years old. Lupus nephritis class - 8 out of 9 patients were class IV, 1 sample was class IV+V. The duration of the corticosteroid therapy is 6.6 years. In addition, we also reviewed the immunosuppressive agents used, the number of flares, and the side effects of the medication.Conclusions. Our data are similar to the literature data.

Background:Classical lupus nephritis (LN) is characterized by glomerular immune complex(IC) deposition with glomerular proliferation, basement membrane destruction and cell infiltration. Non-IC mediated renal injury with thrombotic microangiopathy (TMA) was also reported in patients with systemic lupus erythematosus (SLE-renal TMA), but most studies were reported in patients with both LN and renal TMA.Objectives:In this study, clinical features and outcomes of SLE-renal TMA in absence of obvious IC in SLE patients were analyzed.Methods:Patients with glomerular TMA and/or vascular TMA in the absence of obvious subendothelial or epithelial immune deposits were screened out from 2332 biopsied in SLE patients who underwent first renal biopsy from January 2005 to August 2016. Their clinical, histological features and outcomes were retrospectively analyzed.Results:In 2332 renal biopsies obtained from SLE patients, 257 (11.0%) showed renal TMA, of which 237 showed both renal TMA and LN, and 20 biopsies had only renal TMA (SLE-renal TMA). There were 2 males and 18 females with an average age of (25 ± 10) years. The median course of SLE and LN were 3.0(1.0, 6.0) and 0.8(0.5, 1.9) months. All 20 patients deserved acute kidney injury, of which 11 (55%) needed renal replacement therapy (RRT) and 12 (60%) were nephrotic syndrome. Blood system involvement was found in all cases, including 13 cases (65.0%) with TMA triad (microvascular hemolytic anemia, thrombocytopenia and elevated lactate dehydrogenase).Pathological examination showed that 17 cases (85.0%) had both glomerular TMA and vascular TMA. Immunofluorescence and electron microscopy showed that 8 cases (40%) had no IC deposition in glomerulus and 12 cases (60%) had only IC deposition in mesangium. Acute tubulointerstitial lesions in patients requiring RRT were more serious than those no needing for RRT((43.6±24.9) %vs(21.7±20.1) %,P=0.047). The fusion range of foot process was positively correlated with proteinuria (r2= 0.347,P=0.006).All patients received high-dose methylprednisolone pulse therapy. Four patients received plasma exchange and three patients received gamma globulin, respectively. Eleven patients requiring RRT all stop RRT in a median time of 16.0 (9.0, 30.0) days. During a median follow-up of 58.0 (36.0, 92.3) months, complete remission (CR) was obtained in 15 cases, partial remission in 4 cases and no remission in 1 case. Six cases (30%) relapsed. No case died or progressed to end stage renal disease.Conclusion:Renal injury characterized by TMA is not uncommon in SLE renal biopsy cases. The clinical manifestation is special and the renal injury is serious. The renal outcome is good by intensive immunosuppressive therapy. It should be considered as a unique type of renal injury in SLE.References:[1]Moake JL. Thrombotic microangiopathies. N Engl J Med. 2002. 347(8): 589-600.[2]Anders HJ, Weening JJ.

Background Epidemiological studies in systemic lupus erythematosus have been reported in the literature in many countries and ethnic groups. Although systemic lupus erythematosus in Jamaica has been described in the past, there has not been a detailed evaluation of systemic lupus erythematosus patients in urban Jamaica, a largely Afro-Caribbean population. The goal of this study was to describe the clinical features, particularly disease activity, damage index and immunological features, of 150 systemic lupus erythematosus subjects. Methods 150 adult patients (≥18 years) followed in rheumatology clinic at a tertiary rheumatology hospital centre (one of two of the major public referral centres in Jamaica) and the private rheumatology offices in urban Jamaica who fulfilled Systemic Lupus International Collaborating Clinics (SLICC) criteria were included. Data were collected by detailed clinical interview and examination and laboratory investigations. Hence demographics, SLICC criteria, immunological profile, systemic lupus erythematosus disease activity index 2000 (SLEDAI-2K) and SLICC/American College of Rheumatology (ACR) damage index (SDI) were documented. Results Of the 150 patients, 145 (96.7%) were female and five (3.3%) were male. The mean age at systemic lupus erythematosus onset was 33.2 ± 10.9. Mean disease duration was 11.3 ± 8.6 years. The most prevalent clinical SLICC criteria were musculoskeletal, with 141 (94%) of subjects experiencing arthralgia/arthritis, followed by mucocutaneous manifestations of alopecia 103 (68.7%) and malar rash 46 (30.7%), discoid rash 45 (30%) and photosensitivity 40 (26.7%). Lupus nephritis (biopsy proven) occurred in 42 (28%) subjects and 25 (16.7%) met SLICC diagnostic criteria with only positive antinuclear antibodies/dsDNA antibodies and lupus nephritis on renal biopsy. The most common laboratory SLICC criteria were positive antinuclear antibodies 136 (90.7%) followed by anti-dsDNA antibodies 95 (63.3%) and low complement (C3) levels 38 (25.3%). Twenty-seven (18%) met SLICC diagnostic criteria with only positive antinuclear antibodies/anti-dsDNA antibodies and lupus nephritis on renal biopsy. Mean SLEDAI score was 6.9 ± 5.1 with a range of 0–32. Organ damage occurred in 129 (86%) patients; mean SDI was 2.4 ± 1.8, with a range of 0–9. Conclusion These results are similar to the clinical manifestations reported in other Afro-Caribbean populations; however, distinct differences exist with respect to organ involvement and damage, particularly with respect to renal involvement, which appears to be reduced in our participants.
