ABSTRACT

Objetivo: Determinar la frecuencia de complicaciones materno-perinatales y factores clínicos asociados a estos resultados en estantes con lupus. Métodos: Se realizó un estudio de casos y controles a partir de historias clínicas de pacientes con diagnóstico Lupus Eritematoso Sistémico en embarazo, entre 2010-2022 en una institución de salud en Medellín-Colombia. Éstas se clasificaron como casos (pacientes con resultados adversos materno-perinatales) y controles (pacientes sin resultados adversos). Resultados: Se incluyó un total de 67 pacientes (35 casos y 32 controles). Las complicaciones maternas más frecuentes fueron los trastornos hipertensivos asociados al embarazo (71,4 %), incluyendo preeclampsia y una presentación importante de partos pretérmino (68,6 %). La nefritis lúpica previa y durante el embarazo, fue más frecuente en los casos que en los controles (31,4 % versus 9,4 %). Los compromisos cardiovasculares, de mucosas y musculo-esquelético, fueron más frecuentes durante el embarazo (31,4 %, 40 % y 34,3 %, respectivamente), coincidiendo con mayor actividad del lupus, principalmente durante el embarazo. El compromiso cardiovascular y de mucosas durante el embarazo, así como tener síndrome antifosfolípido se relacionaron con desenlace materno-perinatal adverso. Conclusión: Componentes clínicos propios de la enfermedad como la nefritis lúpica, el síndrome antifosfolípido, el compromiso cardiovascular, y de mucosas podrían predisponer a desenlaces maternos y/o perinatales adversos como trastornos hipertensivos asociados al embarazo, pretérmino, restricción de crecimiento fetal, entre otros(AU)


Objective: To determine the frequency of maternal-perinatal complications and the clinical factors associated with these outcomes in pregnant women with lupus. Methods: A case-control study was conducted using the medical records of patients diagnosed with pregnancy and lupus in a healthcare institution in Medellin, Colombia, between 2010 and 2022. The patients were classified as cases (patients with adverse maternal-perinatal outcomes) and controls (patients without adverse outcomes). Results: A total of 67 patients (35 cases and 32 controls) were included. The most frequent maternal complications were pregnancyassociated hypertensive disorders (71.4%), including preeclampsia and a significant presentation of preterm deliveries (68.6%). Lupus nephritis prior to and during pregnancy was more frequent in cases than in controls (31.4% versus 9.4%). Cardiovascular, mucosal and musculoskeletal compromises were more frequent during pregnancy (31.4%, 40% and 34.3%, respectively), coinciding with greater lupus activity, mainly during pregnancy. Cardiovascular and mucosal involvement during pregnancy, as well as having antiphospholipid syndrome, were related to adverse maternal-perinatal outcome. Conclusion: Clinical components of the disease such as lupus nephritis, antiphospholipid syndrome, cardiovascular and mucosal involvement, are factors that may predispose these patients to adverse maternal and/or perinatal outcomes, such as hypertensive disorders associated with pregnancy, low birth weight, preterm, fetal growth restriction, among others(AU)

ABSTRACT

IgG4-related disease (ER-IgG4) is a group of systemic fibro-inflammatory diseases, whose renal involvement is rare and difficult to diagnose. Diagnosis is usually made by serological and histological studies. Treatment is based on systemic corticosteroids. The renal prognosis is determined by the patient's comorbidities and the degree of fibrosis in the renal biopsy. We present the case of an elderly patient with exacerbated chronic kidney disease, whose study showed nephropathy associated with ER-IgG4.


La enfermedad relacionada a IgG4 (ER-IgG4) es un grupo de enfermedades fibro-inflamatorias sistémicas, cuya afectación renal es poco frecuente y de difícil diagnóstico. Habitualmente el diagnóstico se realiza mediante estudios serológicos e histológicos. El tratamiento se basa en corticoides sistémicos. El pronóstico renal está determinado por las comorbilidades del paciente y el grado de fibrosis en la biopsia renal. Se presenta el caso de un paciente adulto mayor con enfermedad renal crónica reagudizada, cuyo estudio demostró nefropatía asociada a ER-IgG4.

ABSTRACT

Objective:To analyze the impact and diagnostic value of apoB/apoA1 on lupus nephritis (LN) and its renal dysfunction.Methods:A total of 134 patients diagnosed with systemic lupus erythematosus (SLE) at the Taihe Hospital of Anhui University of Traditional Chinese Medicine from July 2019 to January 2023 were selected and divided into LN group ( n=82) and simple SLE group ( n=52). According to the glomerular filtration rate (e-GFR), LN was divided into a group with normal renal function ( n=42) and a group with renal insufficiency ( n=40). We compared the differences in clinical data between different groups and analyzed the diagnostic value of apoB, apoA1, and apoB/apoA1 for LN and its renal insufficiency. Results:The results of binary logistic regression analysis showed that apoB/apoA1, SLE disease activity index (SLEDAI), anti double stranded DNA (dsDNA), complement 3 (C3), and albumin (ALB) were independent influencing factors for LN ( OR=4.033, 1.179, 3.148, 0.374, 0.879, all P<0.05). The area under the curve (AUC) of apoB, apoA1, and apoB/apoA1 for diagnosing LN were 0.623, 0.662, and 0.742, respectively. The diagnostic efficacy of apoB/apoA1 was higher than that of apoB and apoA1, and the differences are statistically significant (all P<0.05). Regardless of whether confounding factors were adjusted or not, apoB/apoA1 were all risk factors for LN with e-GFR>60 ml/(min·1.73 m 2), e-GFR 30-60 ml/(min·1.73 m 2), and e-GFR<30 ml/(min·1.73 m 2) (all P<0.05). ApoB/apoA1, anti dsDNA, C3, and ALB were all independent influencing factors for renal insufficiency LN ( OR=3.778, 2.669, 0.415, 0.884, all P<0.05). The AUC for diagnosing renal insufficiency LN in apoB, apoA1, and apoB/apoA1 were 0.623, 0.640, and 0.730, respectively. The diagnostic efficacy of apoB/apoA1 was higher than that of apoB and apoA1, and the differences were statistically significant (all P<0.05). Conclusions:ApoB/apoA1 is an independent influencing factor for the occurrence of LN and renal insufficiency LN, and has good diagnostic value for LN and renal insufficiency LN.

ABSTRACT

Objective:To investigate the effect of tofacitinib on early atherosclerosis of patients with systemic lupus erythematosus and explore the possible relationship between lupus nephritis and early atherosclerosis of systemic lupus erythematosus.Methods:Sixteen 8-week-old female MRL/lpr mice with a body weight of 20~25 g were selected and randomly divided into the treatment group and placebo group, with 8 mice in each group. The treatment group diluted tofacitinib by normal saline, and given at a dose of 10 mg·kg -1·d -1, and the placebo group (starch tablets) administered the medication in the same way as the treatment group for a total of 8 weeks. The ELISA method was applied to detect serum anti-dsDNA antibody levels in the two groups of mice. Bradford method protein concentration was used to determine the level of urine protein in mice. Automatic biochemical analyzer was used to detect blood lipids, urea nitrogen, serum creatinine, complement C3, complement C4 levels. Western blotting was used to determine the protein expression levels of monocyte chemoattractant protein-1 (MCP-1), non-receptor protein tyrosine kinase family 1 (JAK1), signal transducer and activator of transcription 1 (STAT1) and signal transducer and activator of transcription 2 (STAT2) in aortic and kidney tissues. After the aortic arch section were prepared, oil red O was used to stain the sections, and the vascular plaque area and intimal thickness were evaluated by ImageJ software. The kidneys were dissected and stained with HE, and the active lesions of lupus nephritis were evaluated using the glomerular activity scoring system. SPSS 23.0 software was used for statistical analysis, in which the between-group comparison was performed using two independent samples t-test, and the correlation analysis was performed using the Spearman method. Results:①The serum anti-dsDNA antibody expression level in the treatment group [(5.2±1.0) U/ml] was lower than that in the placebo group [(6.9±1.2) U/ml], ( Z=-3.07, P=0.008), and the levels of complement C3 and complement C4 were higher than those in the placebo group [(293±10) mg/L vs. (260±19) mg/L, Z=2.72, P=0.017]; (16±6) mg/L vs. (8±9) mg/L, Z=3.78, P=0.006]. There was no significant difference in serum BUN and Scr between the treatment group and the placebo group [(10.6±0.7) mmol/L vs. (11.5±1.1) mmol/L, Z=-1.96, P=0.071; (17±5) μmol/L vs. (22±6) μmol/L, Z=-1.79, P=0.095]. ② Compared with the placebo group, the levels of LDL, TC and TG in the treatment group decreased [(0.83±0.15) mmol/L vs. (1.08±1.05) mmol/L, Z=-3.95, P=0.001; (2.90±0.08) mmol/L vs. (1.81±0.97) mmol/L, Z=-5.17, P=0.001; (1.10±0.08) mmol/L vs. (1.60±0.42) mmol/L, Z=-3.23, P=0.013], and HDL level increased [(2.02±0.99) mmol/L vs. (1.81±0.97) mmol/L, Z=4.42, P=0.001]. ③ Compared with the placebo group, the levels of aortic MCP-1, JAK1, STAT1 and STAT2 in the treatment group were reduced [(0.17±0.30) vs. (0.23±0.05), Z=-3.06, P=0.009; (0.83±0.09) vs. (1.05±0.19), Z=-3.07, P=0.008; (0.77±0.07) vs. (0.94±0.13), Z=-2.83, P=0.014; (0.70±0.07) vs. (0.82±0.09), Z=-2.83, P=0.013], the aortic plaque area and aortic intimal thickness were lower than those in the placebo group [(12±31) μm 2vs. (1 242±1 101) μm 2, Z=-3.12, P=0.016; (63±7) μm vs. (82.10±8.06) μm, Z=-5.13, P<0.001]. ④ Compared with the placebo group, the urine protein level and glomerulonephritis activity score in the treatment group were decreased [(0.08±0.03) mg/mL vs. (0.20±0.11) mg/mL, Z=-3.08, P=0.015; (1.79±0.38) vs. (2.79±0.14) points, Z=-7.08, P<0.001)], and renal tissue MCP-1, JAK1, STAT1.Compared with the placebo group, STAT2 levels were reduced [(0.364±0.040) vs. (0.425±0.021), Z=-3.85, P=0.003; (0.689±0.074) vs. (0.838±0.068), Z=-4.19, P=0.001; (0.508±0.070) vs. (0.646±0.019), Z=-2.85, P=0.015; (0.618±0.062) vs. (0.740±0.101), Z=-2.94, P=0.013. ⑤ The glomerular mobility scores of the two groups were positively correlated with LDL, TCHO, TG, aortic plaque area and aortic intimal thickness ( r=0.51, P=0.043; r=0.79, P<0.001; r=0.64, P=0.008; r=0.82, P<0.001; r=0.74, P=0.001), and negatively correlated with HDL ( r=-0.53, P=0.036). The urine protein levels in the two groups were positively correlated with LDL, TC, TG, aortic plaque area and aortic intimal thickness ( r=0.67, P=0.004; r=0.68, P=0.004; r=0.53, P=0.033; r=0.80, P<0.001; r=0.74, P=0.001), and negatively correlated with HDL ( r=-0.57, P=0.021). Conclusion:The severity of lupus nephritis is correlated with atherosclerosis and dyslipidemia in the early stage of systemic lupus erythematosus. Tofacitinib may reduce the degree of early arteriosclerosis and lupus nephritis in MRL/LPR mice, and reduce blood lipid levels, which may be effective in improving the prognosis of SLE and improving the survival rate of patients.

ABSTRACT

The clinical diagnosis of tubulointerstitial nephritis and uveitis (TINU) syndrome combined with Fanconi syndrome is relatively rare. The paper reports a 47-year-old female patient of TINU syndrome with hypokalemia, hypophosphatemia, hypouricemia and renal impairment as initial symptoms followed by uveitis. Serological tests showed that the patient also met the diagnostic criteria of Fanconi syndrome. Renal tissue pathology confirmed tubular interstitial injury, manifested as interstitial nephritis with acute tubular injury. Ophthalmic examination confirmed iritis in the right eye. After excluding other primary diseases, the patient was diagnosed as TINU syndrome with Fanconi syndrome. After glucocorticoid therapy, ocular symptoms, renal impairment and electrolyte disturbance were significantly improved.

ABSTRACT

Objective To analyze the clinical characteristics and regularity of aristolochic acid nephropathy (AAN) induced by drugs containing aristolochic acid. Methods The clinical data of 111 patients with AAN induced by aristolochic acid were reviewed. The clinical features, medication and treatment of AAN were analyzed. Results Among 111 patients, there were more females than males (2.58∶1), 101 cases (90.99%) were over 50 years old; the mean age was (63.70±11.67) years old;the average duration of medication was (8.08±6.94) years. The drugs involved were Guanxinsuhe pill and Longdanxiegan pill in 106 cases (95.50%). Serum creatinine increased in 108 cases, urea nitrogen increased in 106 cases and hemoglobin decreased in 103 cases, most of which were hypogravity urine, mild to moderate proteinuria and occult blood. Ultrasonic examination revealed that the kidneys were damaged to varying degrees. Pathological biopsy of kidney showed renal tubular damage. Most patients had an insidious onset and varying degrees of progression, which were not proportional to the age and the duration of taking the medicine. In clinical, the renal function was progressively damaged, most of which were irreversible and with a poor prognosis. Conclusion Patients with renal impairment differed greatly individually, and the renal damage was not paralleled with the medication duration and dose of drugs containing aristolochic acid.AAN progressed rapidly, and the disease still progressed even after stopping taking drugs containing aristolochic acid. Strengthening pharmacovigilance, implementing early diagnosis and effective intervention could help to reduce the occurrence of AAN and attenuate its development.

ABSTRACT

ObjectiveTo observe the intervention effect of Huaiqihuang granules (HQH) on immunoglobulin A vasculitis nephritis (IgAVN) mice and explore the underlying therapeutic mechanism. MethodFifty SPF-grade male Kunming mice were randomly divided into a normal group, an IgAVN model group, a dexamethasone group (2.5 mg·kg-1·d-1), a low-dose HQH group (4 g·kg-1·d-1), and a high-dose HQH group (8 g·kg-1·d-1). The mouse model was established using oral administration of gliadin combined with intravenous injection of India ink. After successful modeling, the mice were euthanized after 4 weeks of gastric gavage according to groups. The 24 h urinary total protein (24 h UTP), urine β2-microglobulin (β2-MG), serum total protein, albumin, IgA, etc. were detected in each group. Flow cytometry was used to determine the proportion of T helper 17 (Th17) cells in spleen cell suspension. Western blot was employed to detect the expression of adenosine 5'-monophosphate-activated protein kinase α (AMPKα), phosphorylated AMPKα (p-AMPKα), acetyl-CoA carboxylase 1 (ACC1), and phosphorylated ACC1 (p-ACC1) in Th17 cells. Pathological changes in the spleen and kidneys were observed. ResultCompared with the normal group, the IgAVN model group showed significant increases in 24 h UTP, urine β2-MG, total cholesterol (P<0.05), serum interleukin-17 (IL-17), IgA, Th17 proportion in the spleen cell suspension, and IL-17 expression in the spleen tissue (P<0.01), and significantly decreased serum total protein, albumin, p-AMPKα/AMPKα, and p-ACC1/ACC1 expression of Th17 cells (P<0.01). Compared with the IgAVN model group, in the 4th week, the 24 h UTP, urine β2-MG, serum IL-17, IgA levels, and renal IgA deposition were significantly reduced in each treatment group (P<0.01), and the Th17 proportion and IL-17 expression in spleen tissue were significantly decreased (P<0.05, P<0.01). Serum albumin levels significantly increased (P<0.05). Compared with the IgAVN model group, the dexamethasone group and the high-dose HQH group showed increases in serum total protein (P<0.01), p-AMPKα/AMPKα, and p-ACC1/ACC1 expression of Th17 cells (P<0.05, P<0.01). The high-dose HQH group showed a significant decrease in total cholesterol level (P<0.05). Various treatment groups showed different degrees of improvement in spleen and kidney pathological changes. ConclusionHQH may affect Th17 cell differentiation by regulating the AMPK/ACC pathway, correcting immune inflammatory disorders, and exerting therapeutic effects on IgAVN.

ABSTRACT

Objective:To investigate the clinical and pathological characteristics and prognosis of children with lupus nephritis(LN)and thrombotic microangiopathy (TMA).Methods:In this retrospective case-control study, clinical and pathological data of LN children confirmed by renal biopsy from January 2008 to January 2023 in Xuzhou Children′s Hospital, Xuzhou Medical University were analyzed.There were 46 LN children complicated with TMA (LN-TMA group). With matched age, sex and pathology, 92 LN children (1∶2) without TMA were selected as the control group (LN group). The Kaplan-Meier method was used to evaluate the overall and renal survival rates of children with LN, and the Cox regression model was used to analyze the risk factors for the progression to end-stage renal disease (ESRD).Results:TMA was moderately associated with serum creatinine, serum C3, anti-C1q antibody (a-C1q), estimated glomerular filtration rate (eGFR), endocapillary proliferation, fibrinoid necrosis, and renal C1q deposition (all r>0.5). Serum a-C1q≥20 U/mL ( HR=8.724, 95% CI: 0.976-16.114, P=0.026) and eGFR≤60 mL/(min·1.73 m 2) ( HR=12.213, 95% CI: 1.147-25.048, P=0.038) were independent risk factors for TMA in children with LN.Glomerular sclerosis ( HR=7.228, 95% CI: 0.186-22.358, P=0.016), TMA ( HR=11.387, 95% CI: 3.426-42.554, P=0.009) and eGFR≤60 mL/(min·1.73 m 2) ( HR=3.116, 95% CI: 0.592-10.064, P=0.030) were independent risk factors for developing ESRD in LN children.The 5-year and 10-year renal survival rates in the LN-TMA group were lower than those in the LN group (97.44% vs.98.28%, 80.90% vs.87.27%, χ2=4.918, P=0.027). Conclusions:Children with LN-TMA present with severe symptoms and poor prognosis.TMA is an independent risk factor for progression to ESRD in children with LN, and the mechanism may be related to complement activation.

ABSTRACT

OBJECTIVE To systematically evaluate the real-world effectiveness and safety of belimumab in the treatment of lupus nephritis (LN) in Chinese adult patients. METHODS Retrieved from PubMed, Embase, Web of Science, Cochrane Library, Wanfang data, CNKI, VIP and CBM, real-world studies on belimumab in the treatment of LN in Chinese adult patients were collected from the inception to July 7th, 2023. Two reviewers independently screened the literature, extracted data, and assessed the quality of the included studies. Meta-analysis was then performed using RevMan 5.3 software. RESULTS A total of 10 real- world studies were included, involving 253 Chinese adult patients with LN. The results of the meta-analysis demonstrated that the complete renal response rate, partial renal response rate, and the incidence of adverse reaction rate in Chinese adult patients with LN treated with belimumab were 61% (95%CI was 46%-76%, P<0.000 01), 23%(95%CI was 2%-44%, P=0.03), and 30% (95%CI was 16%-43%, P<0.000 01), respectively. Belimumab could reduce the 24-hour urinary protein (MD=-1.71, 95%CI was -3.02--0.40, P=0.01), urine protein-creatinine ratio (MD=-1.76,95%CI was -2.06--1.46,P<0.000 01), the systemic lupus erythematosus disease activity index (MD=-8.63, 95%CI was -12.12--5.13, P<0.000 01), and glucocorticoids dosage (MD=-18.65, 95%CI was -31.82--5.48, P=0.006). In addition, it could elevate the levels of complement C3 (MD=0.19, 95%CI was 0.08-0.30, P=0.000 6) and complement C4 (MD=0.06, 95%CI was 0.02-0.09, P=0.001). However, belimumab could not improve the levels of serum creatinine and estimated glomerular filtration rate (P>0.05). CONCLUSIONS Belimumab has good efficacy and safety in Chinese adult patients with LN.

ABSTRACT

Objective To explore the effect and mechanism of anti-mesangial cell-proliferation-peptide 2(AMPP2)on mesangial cell proliferation induced by transforming growth factor β1(TGF-β1).Methods Mesangial cells were cultured in vitro and treated with TGF-β1(10 μg/L)and AMPP2(10 ng/L).According to different intervention factors,mesangial cells were divided into four groups:the control group,the AMPP2 group,the TGF-β1 group and the TGF-β1+AMPP2 group.The proliferation activity of mesangial cells was detected by CCK-8.The relative protein expression of cyclin dependent kinase 4(CDK-4),cyclin dependent kinase 6(CDK-6),proliferating cell nuclear antigen(PCNA),α-smooth muscle actin(α-SMA),collagen-Ⅰ(COL-Ⅰ)and fibronectin(FN)were examined by Western blot assay.The relative mRNA expression of α-SMA,COL-Ⅰ and FN were detected by qPCR.Results Compared with the control group,proliferation activity of mesangial cells was significantly increased in the TGF-β1 group(P<0.05).The proliferation activity of mesangial cells was markedly decreased in the TGF-β1+AMPP2 group compared with that of the TGF-β1 group(P<0.05).Compared with the control group,protein levels of CDK-4,CDK-6,PCNA,α-SMA,COL-Ⅰand FN in cells were significantly increased in the TGF-β1 group(P<0.05),as well as the mRNA levels of α-SMA,COL-Ⅰand FN(P<0.05).In the TGF-β1+AMPP2 group,the protein and mRNA levels of α-SMA,COL-Ⅰand FN and the protein levels of CDK-4,CDK-6 and PCNA were markedly decreased compared with those of the TGF-β1 group(P<0.05).Compared with the control group,levels of p-SMAD3/SMAD3 was remarkably upregulated in the TGF-β1 group(P<0.05),while levels of p-SMAD3/SMAD3 was remarkably downregulated in the TGF-β1+AMPP2 group compared with those of the TGF-β1 group(P<0.05).Conclusion AMPP2 may inhibit mesangial cell proliferation by regulating TGF-β1/SMAD3 pathway.

ABSTRACT

Objective:To investigate the relationship between serum levels of interleukin-17A (IL-17A) and chemokine ligand 19 (CCL19) and disease activity in patients with lupus nephritis.Methods:A total of 100 patients with lupus nephritis admitted to Affiliated Hospital of Jining Medical College from June 2020 to February 2023 were collected as the disease group, according to the disease activity index, patients were grouped into inactive group (32 cases), mild active group (21 cases), moderate active group (29 cases), and severe active group (18 cases); another 100 healthy individuals who underwent physical examinations in our hospital during the same period were collected as the control group. Enzyme linked immunosorbent assay (ELISA) was applied to detect the expression levels of IL-17A and CCL19 in serum; Pearson method was applied to analyze the correlation between serum IL-17A, CCL19 and routine indicators in patients with lupus nephritis; receiver operating characteristic curve was applied to analyze the diagnostic value of serum IL-17A and CCL19 for moderate/severe lupus nephritis disease activity.Results:The expression levels of IL-17A and CCL19 in the serum of the disease group were obviously higher than those of the control group: (252.63 ± 64.47) ng/L vs. (123.27 ± 25.12) ng/L and (566.98 ± 73.36) ng/L vs. (275.63 ± 50.48) ng/L ( t = 18.70 and 32.72, P<0.05); the serum levels of IL-17A and CCL19 in the severe active, moderate active, and mild active groups were higher than those in the inactive group: (331.42 ± 87.46), (278.50 ± 74.19) and (232.34 ± 59.16) ng/L vs. (198.18 ± 46.22) ng/L; (662.33 ± 89.57), (606.14 ± 79.25) and (552.84 ± 68.36) ng/L vs. (487.13 ± 62.19) ng/L, and with the increase of disease activity, the levels of serum IL-17A and CCL19 gradually increased ( F = 17.86 and 25.35, P<0.05); the glomerular filtration rate, albumin, complement C 3 and complement C 4 in the active group were obviously lower than those in the inactive group: (69.17 ± 13.25) ml/(min·1.73 m 2) vs. (86.18 ± 14.16) ml/(min·1.73 m 2), (24.18 ± 5.11) g/L vs. (31.25 ± 6.35) g/L, (432.35 ± 95.22) mg/L vs. (675.42 ± 125.16) mg/L, (76.58 ± 17.51) mg/L vs. (121.42 ± 27.18) mg/L, while blood creatinine, urine protein and erythrocyte sedimentation rate were obviously higher than those in the inactive group: (92.34 ± 16.24) μmoI/L vs. (53.21 ± 9.17) μmoI/L, (3.43 ± 0.82) g/24 h vs. (1.26 ± 0.23) g/24 h, (66.37 ± 12.28) mm/1 h vs. (35.62 ± 8.67) mm/1 h ( t = 5.86, 5.97, 10.74, 9.93, 12.70, 14.67 and 12.74; P<0.05); serum IL-17A and CCL19 in patients with lupus nephritis were negatively correlated with glomerular filtration rate, albumin, complement C 3, and complement C 4, while positively correlated with blood creatinine, urine protein, and ESR ( P<0.05); the area under the curve (AUC) of the combined diagnosis of serum IL-17A and CCL19 for lupus nephritis disease activity was 0.961, which was superior to their respective individual diagnoses ( Z = 2.24 and 3.16, P = 0.025 and 0.002). Conclusions:The expression levels of IL-17A and CCL19 in serum gradually increase with the increase of disease activity in patients with lupus nephritis. The combined detection of the two has good diagnostic value for disease activity in lupus nephritis.

ABSTRACT

Introducción: Los autoanticuerpos anti-C1q han sido propuestos como un marcador útil en el lupus eritematoso sistémico por su asociación con la nefritis lúpica. Objetivo: Determinar la prevalencia de anti-C1q en pacientes con lupus eritematoso sistémico y otras enfermedades reumáticas para la evaluar la asociación con la nefropatía lúpica. Métodos: Se incluyeron 179 pacientes con lupus eritematoso sistémico y 82 con otras enfermedades reumáticas. La nefritis lúpica fue diagnosticada en 70 (39 por ciento) de los pacientes con lupus eritematoso sistémico. Los anticuerpos anti-C1q IgG se determinaron por ELISA. Las asociaciones se evaluaron por análisis de regresión logística. Resultados: La prevalencia de anti-C1q fue de 37 poe ciento (66/179) en los pacientes con lupus eritematoso sistémico y de 9 por ciento (7/82) en controles (OR = 6,3; IC 95 por ciento 2,8-14,1; p < 0,001). El anti-C1q fue asociado con proteinuria (OR = 2,6; IC 95 por ciento 1,2-6,0; p < 0,022); eritrosedimentación elevada (OR = 3,2; IC 95 por ciento 1,5-6,7; p < 0,003) y anti-DNAdc (OR = 3,9; IC 95 por ciento 1,7-9,1; p < 0,002). En el modelo de regresión logística ajustado para demografía y anti-DNAdc, aunque la OR del anti-C1q para la nefritis fue 2 veces más alta que en ausencia del anti-C1q, solo se aproximó a la significación estadística. La positividad simultánea de anti-C1q y anti-DNAdc estuvo asociada a la nefritis lúpica (OR = 4,3; IC 95 por ciento 1,9-9,5; p < 0,001). Conclusiones: El anti-C1q se presentó con mayor frecuencia en pacientes con lupus eritematoso sistémico que en los controles. El anti-C1q combinado con anti-DNAdc resultó fuertemente asociado a la nefritis lúpica(AU)


Introducción: Anti-C1q autoantibodies have been proposed as useful marker in systemic lupus erythematosus due to their association with lupus nephritis. Objective: To determine the prevalence of anti-C1q in patients with systemic lupus erythematosus and other rheumatic diseases to evaluate the association with lupus nephropathy. Methods: One hundred seventy-nine patients with systemic lupus erythematosus and 82 with other rheumatic diseases were included. Lupus nephritis was diagnosed in 70 (39percent) of patients with systemic lupus erythematosus. Anti-C1q IgG antibodies were determined by ELISA. Associations were evaluated by logistic regression analysis. Results: The prevalence of anti-C1q was 37percent (66/179) in patients with systemic lupus erythematosus and 9percent (7/82) in controls (OR = 6.3; 95percent CI 2.8-14). .1; p < 0.001). Anti-C1q was associated with proteinuria (OR = 2.6; 95percent CI 1.2-6.0; p < 0.022); elevated erythrocyte sedimentation rate (OR = 3.2; 95percent CI 1.5-6.7; p < 0.003) and anti-dsDNA (OR = 3.9; 95percent CI 1.7-9.1; p < 0.002). In the logistic regression model adjusted for demographics and anti-dsDNA, although the OR of anti-C1q for nephritis was 2-fold higher than in the absence of anti-C1q, it only approached statistical significance. Simultaneous positivity of anti-C1q and anti-dsDNA was associated with lupus nephritis (OR = 4.3; 95percent CI 1.9-9.5; p < 0.001). Conclusions: Anti-C1q occurred more frequently in patients with systemic lupus erythematosus than in controls. Anti-C1q combined with anti-dsDNA was strongly associated with lupus nephritis(AU)

ABSTRACT

Abstract Background Kidney disease is a rare manifestation of ankylosing spondylitis (AS) and its pathological alterations remain poorly described. The aim of this study was to investigate the clinical presentation and pathological alterations on kidney biopsy of AS patients and review and discuss the current literature on the issue. Methods: We retrospectively studied the clinical presentation and kidney pathological alterations of 15 Caucasian AS patients submitted to kidney biopsy between October 1985 and March 2021. Results: Patients were predominantly male (66.7%) with median age at the time of kideney biopsy of 47 years [IQR 34 - 62]. Median serum creatinine at presentation was 1.3 mg/dL [IQR 0.9 - 3] and most patients also had either proteinuria (85.7%) and/or hematuria (42.8%). The most common indication for kidney biopsy was nephrotic syndrome (33.3%), followed by acute or rapidly progressive kidney injury (20%) and chronic kidney disease of unknown etiology (20%). Chronic interstitial nephritis (CIN) (n=3) and AA amyloidosis (n=3) were the most common diagnosis. Others included IgA nephropathy (IgAN) (n=2), focal segmental glomerulosclerosis (n=2), membranous nephropathy (n=1), and immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN)(n=1). Conclusions: We present one of the largest series of biopsy-proven kidney disease in Caucasian AS patients. We found a lower prevalence of IgAN than previously reported in Asian cohorts. We found a higher prevalence of CIN and a lower prevalence of AA amyloidosis than that described in previous series of Caucasian patients. We also present the first case of AS-associated IC-MPGN.


Resumo Antecedentes: A doença renal é uma manifestação rara de espondilite anquilosante (EA) e as suas alterações patológicas permanecem pouco descritas. O objetivo deste estudo foi investigar a apresentação clínica e alterações patológicas na biópsia renal de doentes com EA bem como rever e discutir a literatura atual sobre o assunto. Métodos: Estudamos retrospectivamente a apresentação clínica e alterações patológicas renais de 15 doentes caucasianos com EA submetidos a biópsia renal entre Outubro de 1985 e Março de 2021. Resultados: Os doentes eram predominantemente homens (66,7%) com idade mediana no momento da biópsia de 47 anos [IIQ 34 - 62]. A creatinina sérica mediana na apresentação foi de 1,3 mg/dL [IIQ 0,9 - 3] e a maioria dos pacientes apresentava também proteinúria (85,7%) e/ou hematúria (42,8%). A indicação mais comum para biópsia renal foi a síndrome nefrótica (33,3%), seguida de lesão renal aguda ou rapidamente progressiva (20%) e doença renal crónica de etiologia desconhecida (20%). A Nefrite intersticial crónica (NIC) (n=3) e a amiloidose AA (n=3) foram os diagnósticos mais comuns. Outros incluíram nefropatia por IgA (NIgA) (n=2), glomeruloesclerose segmentar focal (n=2), nefropatia membranosa (n=1) e glomerulonefrite membranoproliferativa mediada por imunocomplexos (GNMP-IC) (n=1). Conclusões: Apresentamos uma das maiores séries de doenças renais comprovadas por biópsia em doentes caucasianos com EA. Encontramos uma prevalência de NIgA menor do que a relatada anteriormente em coortes asiáticas. Encontramos uma maior prevalência de NIC e uma prevalência menor de amiloidose AA do que a descrita em séries anteriores de pacientes caucasianos. Também apresentamos o primeiro caso de GNMP-IC associada à EA.

ABSTRACT

Nephrotic syndrome (NS) and glomerulonephritis (GN) are disorders of varied etiologies. Systemic lupus erythematosus (SLE) is one of the multisystemic diseases causing NS and GN. SLE is often suspected whenever NS/GN is associated with extrarenal manifestations. However, it presents solely as NS or GN without extrarenal features in a handful of cases. This affects the prognosis adversely as negligent delay in diagnosis of SLE and initiation of immunosuppressive therapy is associated with poorer response. We present a series of five women who presented solely with renal manifestations. The diagnosis of SLE was delayed, as the women did not have any extrarenal features. We started immunosuppressive therapy after a diagnosis of lupus nephritis was made in retrospect after a kidney biopsy. This case series highlights the importance of performing serology tests for SLE in all young female patients who present with NS/GN to avoid delay in diagnosis.

ABSTRACT

ObjectiveTo investigate the clinical efficacy of Niaoxue No.1 Prescription in treating Henoch-Schönlein purpura (HSP) nephritis with blood heat and stasis syndrome and its effect on urine erythrocyte, urine protein, blood neutrophils, and blood routine-derived indicators. MethodA multicenter, randomized controlled trial (RCT) was conducted involving 108 HSP nephritis patients from three hospitals. The patients were randomly divided into a control group (54 cases) and a treatment group (54 cases). The treatment group received Niaoxue No.1 prescription once daily, while the control group was treated with captopril and ferulic acid tablets. Both groups underwent a 4-week course of treatment. The urine erythrocyte, urine microalbumin (mAlb), urine sediment red blood cell count, traditional Chinese medicine (TCM) syndrome score, 24-hour urine protein, blood neutrophil count, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), D-dimer, and immunoglobulin A were detected. The recurrence rate of HSP nephritis was followed up for 6 months. ResultThe total effective rates were 88.9% (48/54) in the treatment group and 70.4% (38/54) in the control group, and the treatment group was superior to the control group (χ2=5.708, P<0.05). Compared with the results before treatment, after 14 days of treatment, the TCM syndrome total score, urine erythrocyte, urine mAlb, and 24-hour urine protein in both groups significantly decreased (P<0.05,P<0.01), and the improvement was more significant in the treatment group than the control group (P<0.05). After 28 days of treatment, compared with the results before treatment, the TCM syndrome total score, urine erythrocyte, urine mAlb, urine sediment red blood cell count, D-dimer, and 24-hour urine protein in both groups significantly decreased (P<0.05,P<0.01), with the treatment group showing a more significant reduction in urine mAlb than the control group (P<0.05). On the 14th and 28th days of treatment, the neutrophil percentage and NLR were lower in the treatment group than in the control group (P<0.05), while there was no statistically significant difference in PLR and LMR. The recurrence rate of nephritis in both groups showed no statistically significant difference after a 6-month follow-up. ConclusionNiaoxue No.1 Prescription in the treatment of HSP nephritis with blood heat and stasis syndrome can significantly improve clinical symptoms, shorten the course of the disease, and reduce urine erythrocyte, urine mAlb, 24-hour urine protein, blood neutrophils, and NLR, thereby effectively alleviating the inflammatory state and reducing kidney damage in children with HSP nephritis.

ABSTRACT

OBJECTIVES@#To investigate the clinical characteristics, pathology, and prognosis of children with diffuse endocapillary proliferative Henoch-Schönlein purpura nephritis (DEP-HSPN).@*METHODS@#A retrospective analysis was performed on the clinical, pathological, and prognosis data of 44 children with DEP-HSPN and 765 children without DEP-HSPN. The children with DEP-HSPN were diagnosed by renal biopsy in Jiangxi Provincial Children's Hospital from January 2006 to December 2021.@*RESULTS@#Among the 809 children with purpura nephritis, 44 (5.4%) had DEP-HSPN, with a mean age of (8±3) years, and there were 29 boys (65.9%) and 15 girls (34.1%). Compared with the non-DEP-HSPN group, the DEP-HSPN group had a significantly shorter time from onset to renal biopsy and a significantly higher proportion of children with respiratory infection or gross hematuria, and most children had nephrotic syndrome. The DEP-HSPN group had significantly higher levels of 24-hour urinary protein, urinary protein grading, microscopic hematuria grading, serum creatinine, and blood urea nitrogen and significantly lower levels of serum albumin and complement C3 (P<0.05). The DEP-HSPN group had a higher pathological grading, with predominant deposition of IgA in the mesangial area and capillary loops, and higher activity scores in the modified semi-quantitative scoring system (P<0.05). The Kaplan-Meier survival analysis showed that there was no significant difference in the renal complete remission rate between the two groups (P>0.05).@*CONCLUSIONS@#Children with DEP-HSPN have a rapid onset, severe clinical manifestations and pathological grading, and high activity scores in the modified semi-quantitative scoring system. However, most of the children with DEP-HSPN have a good prognosis, with a comparable renal complete remission rate to the children without DEP-HSPN.

ABSTRACT

OBJECTIVES@#To investigate the difference in the therapeutic effect of mycophenolate mofetil (MMF) or cyclophosphamide (CTX) in children with Henoch-Schönlein purpura nephritis (HSPN) of different age groups.@*METHODS@#A retrospective analysis was conducted on the clinical data of 135 children with HSPN who were treated with MMF or CTX in the Department of Nephrology, Children's Hospital Affiliated to Capital Institute of Pediatrics, from October 2018 to October 2020. According to the immunosuppressant used, they were divided into two groups: MMF group and CTX group, and according to the age, each group was further divided into two subgroups: ≤12 years and >12 years, producing four groups, i.e, the ≤12 years MMF subgroup (n=30), the >12 years MMF subgroup (n=15), the ≤12 years CTX subgroup (n=71), and the >12 years CTX subgroup (n=19). All children were followed up for at least 12 months, and the above groups were compared in terms of clinical outcomes and the incidence rate of adverse reactions.@*RESULTS@#There was no significant difference in the complete response rate between the MMF group and the CTX group after 3, 6, and 12 months of treatment (P>0.05). There were no significant difference in the complete response rate and the incidence rate of adverse reactions between the >12 years MMF subgroup and the ≤12 years MMF subgroup at 3, 6, and 12 months of treatment (P>0.05). The >12 years CTX subgroup had a significantly lower complete response rate than the ≤12 years CTX subgroup at 6 and 12 months of treatment (P<0.05). The >12 years CTX subgroup had a significantly higher incidence rate of adverse reactions than the >12 years MMF subgroup (P<0.05).@*CONCLUSIONS@#The efficacy and adverse reactions of MMF are not associated with age, but the efficacy of CTX is affected by age, with a higher incidence rate of adverse reactions. CTX should be selected with caution for children with HSPN aged >12 years.
