Background Lupus nephritis (LN) is an ominous manifestation of systemic lupus erythematosus (SLE). Clinical renal affection is present in about 70% of lupus patients, and more patients have histological evidence of renal involvement without clinical manifestations. This study aimed to investigate the potential role of serum interleukin-34 (IL-34) as an early marker for the detection of silent LN. Methods Thirty-three lupus patients with silent LN (group I), 37 patients with clinical LN (group II) and 20 controls were included. The SLE Disease Activity Index (SLEDAI), IL-34, anti-dsDNA antibodies and renal biopsy were assessed in all patients. Results Serum IL-34 levels were significantly higher in all lupus patients compared to healthy controls ( p < 0.001) and showed a significant positive correlation with SLEDAI score. SLE patients with positive anti-dsDNA antibodies had more active disease according to SLEDAI and higher levels of IL-34 than those with negative anti-dsDNA antibodies. In both studied groups, serum IL-34 levels were significantly higher in patients with proliferative LN (class III and class IV) than those with non-proliferative lupus (class II and class V) and controls. Yet, in both groups, IL-34 was not useful in differentiating active from chronic renal affection. Conclusion In lupus patients with insignificant proteinuria, serum levels of IL-34 distinguished the different histological classes of subclinical LN. Serum IL-34 may be used as a surrogate marker for early renal affection in silent LN, especially the proliferative type.

THE AIM: to evaluate the effect of allelic variations in the hemostatic system genes on the development and course of lupus nephritis. PATIENTS AND METHODS. The study analyzed 100 patients with SLE Caucasians. 80 women and 20 men aged 16 to 73 years (mean age 37, ± 14 years). The duration of observation was for 73 patients over 5 years, for 18 – from 1 year to 5 years and for 9 – less than 1 year A rise in the level of creatinine in the blood above or equal to 2 mg / dl was considered a significant sign of impaired renal function. RESULTS. Among the patients included in the study, kidney damage was detected in 61 people (61%). In 33 of them (54.1%), a variant of renal pathology was observed according to the type of rapidly progressive lupus nephritis (BPVN). In patients with BH, mutations in the MTHFR (C677T) gene were statistically significantly more frequent (p = 0.033). The OR for the mutant genotype is 6.146 with 95% CI from 1.692 to 22.326. In patients with PWHD, mutations in the MTHFR (C677T) gene were statistically significantly more frequent (p = 0.031). The OR for the mutant genotype is 1.625 with 95% CI from 1.034 to 4.771. The five-year renal survival in carriers of the mutant allele of the MTHFR gene (C677T) is statistically significantly lower (72.8%) than in patients without this mutation (81.9%) (p = 0.027). Ten-year renal survival in carriers of the mutant allele of the MTHFR gene (C677T) is statistically significantly less (55.6%) than in patients without this mutation (70.5%) (p = 0.016). In patients with BH, mutations in the PAI-1 gene (4G / 5G 675) were statistically significantly more frequent (p = 0.046). OR for mutant genotype – 1.766 with 95% CI from 1.061 to 4.758. CONCLUSION. The mutant alleles of the MTHFR (C677T) and PAI-1 (4G / 5G 675) genes are likely to be associated with the development of BH. Polymorphism of the MTHFR gene (C677T) is associated with an unfavorable course of HH.

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease. Few biomarkers for SLE have been validated and widely accepted for the laboratory follow-up of inflammatory activity. In SLE patients, with lupus nephritis (LN), complement activation leads to fluctuation of serum C3 and C4 that are frequently used as clinicalm biomarker of disease activity in SLE. Patients and Methods: In this study the number of patients were 37, seven patients were excluded for incomplete data collection, 28 were females ,2 were males. The duration of the study is two years from 2015 to 2017. Patients were considered to have SLE and LN according to American College of Rheumatology (ACR) criteria, and International Society of Nephrology/ Renal Pathology Society (ISN/RPS). All patients were evaluated withm clinical presentation, laboratory investigations. Our patients underwent kidney biopsy according to standard procedure by Kerstin Amann, and their tissue specimens were studied in the laboratory with light microscope (LM) and immunofluorescence microscope reagents. The relationship between the serological markers and immunofluorescence deposits in kidney biopsy of all patients were studied using the statistical analysis of Pearson correlation and single table student's T test. A P value 0.05 was considered statistically significant. Results: The granular pattern of IF deposits was present in all LN patients, and in more than two third of patients these IF deposits presented in glomerular, tubular, and mesangium sites. While less than one third of patients had IF deposits in the mesangium only. There was no statistically significant correlation between serum ANA, anti-dsDNA, and IF deposits of different types. There was significant correlation between serum C3 and C4 hypocomplementemia and IgG immune deposits in kidney biopsy, and there was significant relationship between serum C3 hypocomplementemia and full house immunofluorescence (FHIF) deposits inm kidney biopsy.Conclusions:Immunofluorescence deposits is mainly granular pattern in LN patients. There was no significant association between serum ANA, anti-dsDNA, and immune deposits in kidney tissue. Immunofluorescence deposits of IgG type correlates significantly with serum C3 and C4 hypocomplemetemia, and these immune deposits in association with low complement levels correlates with LN flare. There was significant correlation between C3 hypocomplementemia and FHIF.
