- Systemic amyloidosis journey from diagnosis to outcomes: a twelve-year real-world experience of a single center in a middle-income country(2022) SZOR, Roberta Shcolnik; FERNANDES, Fabio; LINO, Angelina Maria Martins; MENDONCA, Leonardo Oliveira; SEGURO, Fernanda Salles; FEITOSA, Valkercyo Araujo; CASTELLI, Jussara Bianchi; JORGE, Lecticia Barbosa; ALVES, Lucas Bassolli de Oliveira; NEVES, Precil Diego Miranda de Menezes; SOUZA, Evandro de Oliveira; CAVALCANTE, Livia Barreira; MALHEIROS, Denise; KALIL, Jorge; MARTINEZ, Gracia Aparecida; ROCHA, VandersonBackground: Systemic amyloidosis is caused by the deposition of misfolded protein aggregates in tissues, leading to progressive organ dysfunction and death. Epidemiological studies originate predominantly from high-income countries, with few data from Latin America. Due to the non-specific clinical manifestations, diagnosing amyloidosis is often challenging and patients experience a long journey and delay in diagnosis. This study aimed to assess clinical and laboratory characteristics, the diagnostic journey, and outcomes of patients with biopsy-proven systemic amyloidosis diagnosed between 2009 and 2020 at a university referral center in a middle-income Latin American country. Patients' medical records were retrospectively reviewed. Results: One hundred and forty-three patients were included. The median age at diagnosis was 60 years and 54% were male. Until the diagnosis, most of the patients (52%) were seen by at least 3 specialists, the main ones being: general practitioners (57%), nephrologists (45%), and cardiologists (38%). The most common manifestations were renal (54%) and cardiac (41%) disorders, and cachexia was seen in 36% of patients. In 72% of the cases, & GE; 2 biopsies were required until the final diagnosis. The median time from symptoms onset to diagnosis was 10.9 months, and most patients (75%) had & GE; 2 organs involved. The following subtypes were identified: AL (68%), ATTR (13%), AA (8%), AFib (4%), and inconclusive (7%). Median OS was 74.3 months in the non-AL subgroup and 18.5 months in AL. Among AL patients, those with advanced cardiac stage had the worst outcome [median OS 8.6 months versus 52.3 for stage III versus I-II, respectively (p < 0.001)]. AL subtype, cardiac involvement, and ECOG & GE; 2 were identified as independent risk factors for reduced survival. Conclusions: Systemic amyloidosis is still an underdiagnosed condition and the delay in its recognition leads to poor outcomes. Medical education, better diagnostic tools, improvement in access to therapies, and establishment of referral centers may improve patient outcomes in middle-income countries.
- Methimazole-Induced ANCA Vasculitis: A Case Report(2021) NEVES, Precil Diego Miranda de Menezes; MOTA, Lucas Braga; DIAS, Cristiane Bitencourt; YU, Luis; WORONIK, Viktoria; CAVALCANTE, Livia Barreira; MALHEIROS, Denise Maria Avancini Costa; JORGE, Lecticia BarbosaRapidly progressive glomerulonephritis (RPGN) is a syndrome which presents rapid loss of renal function. Vasculitis represents one of the major causes, often related to anti-neutrophil cytoplasmic antibodies (ANCA). Herein, we report a case of methimazole-induced ANCA-associated vasculitis. A 35-year-old woman complained of weight loss and fatigue for 2 weeks and attended the emergency room with alveolar hemorrhage. She had been diagnosed with Graves' disease and had been taking methimazole in the past 6 months. Her physical examination showed pulmonary wheezing, hypertension and signs of respiratory failure. Laboratory tests revealed urea 72 mg/dL, creatinine 2.65 mg/dL (eGFR CKD-EPI: 20 mL/min/1.73 m(2)), urine analysis with >100 red blood cells per high-power field, 24 h-proteinuria: 1.3 g, hemoglobin 6.6 g/dL, white-cell count 7700/mm(3), platelets 238,000/mm(3), complement within the normal range, negative viral serological tests and ANCA positive 1:80 myeloperoxidase pattern. Chest tomography showed bilateral and diffuse ground-glass opacities, and bronchial washing confirming alveolar hemorrhage. A renal biopsy using light microscopy identified 27 glomeruli (11 with cellular crescentic lesions), focal disruption in glomerular basement membrane and fibrinoid necrosis areas, tubulitis and mild interstitial fibrosis. Immunofluorescence microscopy showed IgG +2/+3, C3 +3/+3 and Fibrinogen +3/+3 in fibrinoid necrosis sites. She was subsequently diagnosed with crescentic pauci-immune glomerulonephritis, mixed class, in the setting of a methimazole-induced ANCA vasculitis. The patient was treated with methimazole withdrawal and immunosuppressed with steroids and cyclophosphamide. Four years after the initial diagnosis, she is currently being treated with azathioprine, and her exams show creatinine 1.30 mg/dL (eGFR CKD-EPI: 52 mL/min/1.73 m(2)) and negative p-ANCA.
- Atypical presentation of acute post-infectious glomerulonephritis in patients with sickle cell disease: report of two cases(2020) NEVES, Precil Diego Miranda de Menezes; REICHERT, Bernardo Vergara; BRIDI, Ramaiane Aparecida; YU, Luis; DIAS, Cristiane Bitencourt; PINHEIRO, Rafaela Brito Bezerra; TESTAGROSSA, Leonardo de Abreu; CAVALCANTE, Livia Barreira; MALHEIROS, Denise Maria Avancini Costa; JORGE, Lecticia Barbosa; WORONIK, ViktoriaBackgroundSickle cell disease (SCD) is a highly prevalent genetic disease worldwide. In the natural evolution of SCD, glomerular lesions can develop, presenting histopathological patterns of segmental or focal membranoproliferative glomerulosclerosis, with or without thrombotic microangiopathy. We report two cases of acute post-infectious glomerulonephritis (APIGN), with atypical presentations, in patients with SCD.Case presentationCase 1: An 18-year-old female with SCD presented with a 21-day history of progressive oedema, accompanied by dyspnoea, productive cough, fever, and chest pain. Blood tests showed the following: haemoglobin 6.1g/dl; leucocytes 18,820 cells/mm(3); and creatinine 0.49mg/dl. A urine sample evidenced leucocyturia and haematuria. The 24-h proteinuria was 8.99g, serum albumin level was 1.2g/dl, low serum C3 levels and high levels of anti-streptolysin O. Renal biopsy was consistent with APIGN. The patient was treated with diuretic and anti-proteinuric agents, subsequently evolving to reversal of the renal alterations. Case 2: A 12-year-old male with SCD presented with a 20-day history of a non-productive cough and progressive oedema, together with hypertension. The serum creatinine concentration was 0.48mg/dl. A urine sample evidenced leukocyturia and haematuria. The 24-h proteinuria was 12.5g, and the serum albumin level was 2.6g/dl. The levels of C3 and C4 were normal. Renal biopsy revealed APIGN. The patient was treated with diuretic and anti-proteinuric agents, subsequently evolving reversal of the renal alterations.ConclusionsThe presentation of the two cases reported here are not typical of SCD-related kidney injury. Analysis of the renal biopsy specimens elucidated the diagnosis, affecting the prognosis, because that of APIGN is highly favourable, unlike that of nephrotic syndrome associated with SCD glomerulopathy.
- IgA nephropathy in patients with serum anti-neutrophil cytoplasmic autoantibody (ANCA) positivity: case series(2022) DIAS, Cristiane Bitencourt; JORGE, Lecticia Barbosa; WORONIK, Viktoria; CAVALCANTE, Livia Barreira; YU, LuisSome cases of patients with IgA nephropathy diagnosed via kidney biopsy and antineutrophil cytoplasmic antibody (ANCA) positivity have been reported. This article describes a case series comprising patients with IgA nephropathy and ANCA positivity seen at a medical center in the city of Sao Paulo, Brazil, from 1996 to 2016. A total of 111 patients underwent diagnostic kidney biopsies for IgA nephropathy. Five were ANCA-positive at the time of diagnosis; their mean age was 45 +/- 15.3 years and they were predominantly females with a mean proteinuria of 2.2 +/- 0.9 g/day and a median serum creatinine level of 2.5 (2.0 - 8,6) mg/dL; all had hematuria. Four of the five were cANCApositive (80%); all had normal serum C3 and C4 levels; and 80% were positive for ANA. One case presented an association with infection, but no associations were found with medication. One patient had granuloma and another had a collapsing lesion. This article describes the cases of five ANCA-positive patients (with predominantly cANCA positivity) submitted to diagnostic kidney biopsies for IgA nephropathy; one patient had a collapsing lesion, but progressed well.
- Schistosoma mansoni infection as a trigger to collapsing glomerulopathy in a patient with high-risk APOL1 genotype(2020) NEVES, Precil D.; BRIDI, Ramaiane A.; RAMALHO, Janaina A.; JORGE, Lecticia B.; WATANABE, Elieser H.; WATANABE, Andreia; YU, Luis; WORONIK, Viktoria; PINHEIRO, Rafaela B.; TESTAGROSSA, Leonardo A.; CAVALCANTE, Livia B.; MALHEIROS, Denise M.; DIAS, Cristiane B.; ONUCHIC, Luiz F.Author summary Schistosomiasis mansoni is still a public health problem in Brazil and renal involvement is described. In such cases, a glomerulopathy is the typical manifestation, most often membranoproliferative glomerulonephritis. In the current article, we report a patient with a recent diagnosis of hepatosplenic SM who was admitted for nephrotic syndrome associated with reduced renal function and hypertension. Kidney biopsy established the diagnosis of collapsing glomerulopathy (CG) and molecular genetics investigation identified a high-risk APOL1 genotype (HRG). Of note, HRG has been associated with increased risk to develop CG, and a two-hit model has been proposed for the genesis of this glomerulopathy. According to this model, a HRG represents the increased-susceptibility component, while an infection or other environmental factors could act as triggers for the development of CG. Based on those data and model, our case raises SM infection as a new trigger for this severe form of glomerulopathy. This is the first description of a case of CG associated with SM in a patient with an HRG. This case corroborates the interactive role between genetic and environmental factors in the pathogenesis of CG but also identifies SM infection as an additional trigger for its development. Background Schistosoma mansoni schistosomiasis (SM) remains a public health problem in Brazil. Renal involvement is classically manifested as a glomerulopathy, most often membranoproliferative glomerulonephritis or focal and segmental glomerulosclerosis. We report a case of collapsing glomerulopathy (CG) associated with SM and high-risk APOL1 genotype (HRG). Case report A 35-year-old male was admitted for hypertension and an eight-month history of lower-limb edema, foamy urine, and increased abdominal girth. He had a recent diagnosis of hepatosplenic SM, treated with praziquantel, without clinical improvement. Laboratory tests revealed serum creatinine 1.89mg/dL, blood urea nitrogen (BUN) 24mg/dL, albumin 1.9g/dL, cholesterol 531mg/dL, low-density lipoprotein 426mg/dL, platelets 115000/mm(3), normal C3/C4, antinuclear antibody (ANA), rheumatoid factor (RF), and antineutrophil cytoplasmic antibodies (ANCA), negative serologies for hepatitis C virus (HCV) and human immunodeficiency virus (HIV), HBsAg negative and AntiHBc IgG positive, no hematuria or leukocyturia, 24 hour proteinuria 6.56g and negative serum and urinary immunofixation. Kidney biopsy established the diagnosis of CG. A treatment with prednisone was started without therapeutic response, progressing to end-stage kidney disease 19 months later. Molecular genetics investigation revealed an HRG. Conclusions This is the first report of CG associated with SM in the setting of an HRG. This case highlights the two-hit model as a mechanism for CG pathogenesis, where the high-risk APOL1 genotype exerts a susceptibility role and SM infection serves as a trigger to CG.
- Evidences of histologic thrombotic microangiopathy and the impact in renal outcomes of patients with IgA nephropathy(2020) NEVES, Precil Diego Miranda de Menezes; SOUZA, Rafael A.; TORRES, Fabio M.; REIS, Fabio A.; PINHEIRO, Rafaela B.; DIAS, Cristiane B.; YU, Luis; WORONIK, Viktoria; FURUKAWA, Luzia S.; CAVALCANTE, Livia B.; ARAUJO, Stanley de Almeida; WANDERLEY, David Campos; MALHEIROS, Denise M.; JORGE, Lecticia B.Introduction IgA nephropathy (IgAN) is the most common primary glomerulopathy worldwide. According to the Oxford Classification, changes in the kidney vascular compartment are not related with worse outcomes. This paper aims to assess the impact of thrombotic microangiopathy (TMA) in the outcomes of Brazilian patients with IgAN. Materials and methods Analysis of clinical data and kidney biopsy findings from patients with IgAN to assess the impact of TMA on renal outcomes. Results The majority of the 118 patients included were females (54.3%); mean age of 33 years (25;43); hypertension and hematuria were observed in 67.8% and 89.8%, respectively. Median creatinine: 1.45mg/dL; eGFR: 48.8ml/min/1.73m(2); 24-hour proteinuria: 2.01g; low serum C3: 12.5%. Regarding to Oxford Classification: M1: 76.3%; E1: 35.6%; S1: 70.3%; T1/T2: 38.3%; C1/C2: 28.8%. Average follow-up: 65 months. Histologic evidence of TMA were detected in 21 (17.8%) patients and those ones presented more frequently hypertension (100% vs. 61%, p <0.0001), hematuria (100% vs 87.6%, p = 0.0001), worse creatinine levels (3.8 vs. 1.38 mg/dL, p = 0.0001), eGFR (18 vs. 60 ml/min/1.73m(2)), p = 0.0001), low serum C3 (28.5% vs. 10.4%, p = 0.003), lower hemoglobin levels (10.6 vs. 12.7g/dL, p0.001) and platelet counts (207,000 vs. 267,000, p = 0.001). Biopsy findings of individuals with TMA revealed only greater proportions of E1 (68% vs. 32%, p = 0.002). Individuals with TMA were followed for less time (7 vs. 65 months, p<0.0001) since they progressed more frequently to chronic kidney disease (CKD) requiring kidney replacement therapy (KRT) (71.4% vs. 21,6%, p<0.0001). Male sex, T1/T2, and TMA were independently associated with progression to CKD-KRT. Conclusions In this study patients with TMA had worse clinical manifestations and outcomes. In terms of histologic evidence, E1 distinguished patients with TMA from other patients. Further studies are necessary to analyze the impact of vascular lesions on IgAN prognosis.
- Schistosomiasis-associated glomerulopathy: Clinical aspects, pathological characteristics, and renal outcomes(2020) NEVES, Precil Diego Miranda de Menezes; JORGE, Lecticia Barbosa; CAVALCANTE, Livia Barreira; MALHEIROS, Denise; WORONIK, Viktoria; DIAS, Cristiane BitencourtBackground: In Brazil, schistosomiasis is caused only by Schistosoma mansoni, occurring in the northeastern and southeastern regions. Schistosomiasis primarily affects the liver and gastrointestinal tract, although the kidneys can also be affected, mainly in the form of glomerulopathics. Here, we describe the characteristics of patients with schistosomiasis-associated glomerulopathies, including treatment and renal outcomes. Materials and methods: This was a retrospective analysis of patients diagnosed with schistosomiasis-associated glomerulopathy between 2002 and 2017. Clinical, biochemical, and histopathological (kidney biopsy) data were evaluated. Results: Of the 24 patients evaluated, 19 (79.1%) were male and 16 (66.4%) were White. The mean age was 38.58 +/- 9.83 years. We observed the hepatosplenic form of schistosomiasis in 15 patients (68.1%). nephrotic-nephritic syndrome in 13 (54.1%), hematuria in 20 (83.3%), and hypertension in 18 (75.0%). Renal histology showed a predominance of membranoproliferative pattern (n = 17/70.8%). On immunolluorescence, 19 patients (82.6%) showed immunoglobulin M (IgM) expression, 10 (43.4%) showed IgM+IgG expression, and 1(4.3%) showed a ""full house"" pattern. The median follow-up time was 59.70 months, by the end of which 9 patients (37.5%) had developed end-stage renal disease (ESRD). Baseline serum creatinine was higher among the patients who developed ESRD than among those who did not (1.99 +/- 1.08 vs. 1.34 +/- 0.46 mg/dL, p = 0.05). Conclusion: Our study is one of the rare clinical studies on schistosomiasis-associated glomerulopathy with a long follow-up and renal endpoints, showing that one third of our patients, independent of their histological form, progress to dialysis.
- Renal thrombotic microangiopathy associated to worse renal prognosis in Lupus Nephritis(2021) STRUFALDI, Fernando Louzada; NEVES, Precil Diego Miranda de Menezes Menezes; DIAS, Cristiane Bitencourt; YU, Luis; WORONIK, Viktoria; CAVALCANTE, Livia Barreira; MALHEIROS, Denise Maria Avancini Costa; JORGE, Lecticia BarbosaIntroduction Renal thrombotic microangiopathy (rTMA) is one of many vascular findings in Lupus Nephritis (LN). However, the influence of rTMA on prognosis has not been well established. The objective of this study was to evaluate the clinical and pathological aspects of patients with lupus and rTMA in kidney biopsy. Methods Analysis of medical reports and kidney biopsy of 253 patients with LN, between January 2012 and December 2018. Results Among our 253 patients, 43 (17%) showed acute or chronic TMA lesions on kidney histology This group had a significantly lower estimated glomerular filtration rate (eGFR) at the time of biopsy (24.1 vs. 64.15 ml/min/1.73m2, p < 0.001), at 1 year of follow up (28.1 vs. 90.7 ml/min/1.73m2, p < 0.001), and at the end of follow up (25.4 vs. 81.55 ml/min/1.73m2, p < 0.001). More patients in the rTMA group reached the composite endpoint of eGFR < 15 mL/min/1.73m2 or death or dialysis (82.9% vs. 32.9%, p < 0.001). When comparing the classical clinical TMA features, the rTMA group had higher percentages of anemia, thrombocytopenia, low haptoglobin levels, but not higher lactate dehydrogenase (LDH) levels (> 214 U/L). Combining these variables in a definition of clinical TMA, the rTMA group had a statistically higher percentage of clinical TMA (20.9% vs. 4.33%, p = 0.001). As expected, TMA group showed higher systolic blood pressure (SBP) (130 vs 129.5 mmHg, p = 0.01). Concerning histopathological features, rTMA group had significantly higher activity (9.0 vs. 6.0, p = 0.001) and chronicity (4.0 vs. 3.0, p = 0.001) scores, also a higher percentage of patients presented with crescents (76.7% vs. 57.1%, p = 0.012). Conclusions The classical clinical TMA criteria were unable to predict the presence of tissue TMA, suggesting a probably renal-limited TMA that may occur independently of systemic evident factors. Therefore, renal biopsy remains the critical method for diagnosing an important prognostic feature.
- Renal Outcomes in Brazilian Patients with Immunoglobulin A Nephropathy and Cellular Crescentic Lesions(2020) NEVES, Precil Diego Miranda de Menezes; PINHEIRO, Rafaela Bezerra Brito; DIAS, Cristiane Bitencourt; YU, Luis; TESTAGROSSA, Leonardo de Abreu; CAVALCANTE, Livia Barreira; MALHEIROS, Denise Maria Avancini Costa; JORGE, Lecticia Barbosa; WORONIK, ViktoriaBackground and Aim: Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulopathy. The Oxford classification was recently updated to include crescents as markers of poor prognosis. The aim of this study was to evaluate the impact of cellular crescents on the prognosis of patients with IgAN in Brazil. Methods: This was a single-centre retrospective analysis of medical records and renal biopsies in patients with IgAN. The renal biopsy findings were classified according to the revised Oxford classification: mesangial hypercellularity, endocapillary hypercellularity (E), segmental glomerulosclerosis (S), tubular atrophy or interstitial fibrosis (T), and crescent formation (C). We evaluated a composite outcome (progression to end-stage renal disease or creatinine doubling). We performed analyses between the patients with crescents in the renal biopsy specimen (C1/C2 group) and those without such crescents (C0 group). Results: We evaluated 111 patients, of whom 72 (65.0%) were women, 80 (72.0%) self-identified as White, 73 (65.6%) were hypertensive, and 95 (85.6%) had haematuria. The distribution of patients according to cellular crescentic lesions was: C0, 80 (72%); C1, 27 (24.4%); C2, 4 (3.6%). The composite outcome was observed in 33 (29.72%) of the 111 patients. In comparison with the C0 group, the C1/C2 group had higher proportions of patients with hypertension (p = 0.04), haematuria (p = 0.03), worse serum creatinine (p = 0.0007), and worse estimated glomerular filtration rate (p = 0.0007). The C1/C2 group also had higher proportions of patients in whom the biopsy specimen was classified as E1 (p = 0.009), S1 (p = 0.001), or T1/T2 (p = 0.03), In addition, the mean follow-up period was shorter in the C1/C2 group (p < 0.0001). Furthermore, the composite outcome was observed in a greater proportion of patients and in a shorter length of time in the C1/C2 group than in the C0 group (p = 0.002 and p = 0.0014, respectively). In a Cox regression analysis, the independent risk factors for the composite outcome had Oxford classifications of S1, T1/T2, and C1/C2. Conclusion: Oxford classification findings of S1, T1/T2, or C1/C2 were independent risk factors for the composite outcome, corroborating previous studies.
