Abstract Background and Aim. IgA nephropathy (IgAN) is the most common chronic primary glomerulonephritis leading to progressive renal failure in 1/3 of patients. Although it is a limited non-systemic renal disease, many systemic diseases, such as Systemic Lupus Erythematosus (SLE), are sporadically associated with mesangial IgA deposits. We investigate frequency and meaning of ANA positivity in IgAN. Methods. All biopsy-proven IgAN patients followed in our Unit with ANA positivity were selected. Data are compared by non parametric test (Wilcoxon signed-rank test). Results. 15/68 (22%) IgAN patients resulted ANA+ during a 9-year median follow-up. 10 were females and five were male. Mean age was low. Renal function was normal in 9/15. 24 h Proteinuria was non nephrotic in 15/16. In 10 patients there was low C3. Patient characteristics are summarized in Table 1. At follow-up, renal function did not change significantly (p=NS), however mean 24h-Uprot reduced (p=0.075) Table 2. One male developed SLE, one female a lupus-like Mixed Connective Tissue Disease. Conclusions. Our data suggest that 1) in 22% of IgAN patients ANA positivity could be detected; 2) ANA+ IgAN patients are mostly women with normal renal function and non nephrotic proteinuria; 3) after a median 9-year follow-up, ANA+ IgAN patients, on therapy, presented a stable renal function and a reduced proteinuria; 4) ANA+ IgAN patients could develop SLE. More clinical observations and studies are needed for supporting the hypothesis that IgAN+ANA positivity could be part of a new clinical entity of SLE patients.

A 42-year-old woman presented with chronic fever, abdominal pain, intermittent loose stools and dysuria for 3 months. She had recently developed acute dyspnoea with acute kidney injury. She was found to have a contracted, thick-walled bladder with bilateral hydroureteronephrosis. She underwent bilateral percutaneous nephrostomies, following which her renal function recovered. She satisfied the clinical and immunological features of the Systemic Lupus International Collaborating Clinics criteria for systemic lupus erythematosus (SLE). She was initiated on immunosuppression. Lupus cystitis with a contracted bladder is an uncommon presentation of SLE.

Objective Lupus nephritis (LN) is closely associated with hyperuricemia, and uric acid is considered a risk factor for renal involvement in systemic lupus erythematosus (SLE). This study aimed to examine the association between serum uric acid (SUA) level and LN development and progression in SLE patients with normal renal function. Methods A total of 60 SLE patients with normal renal function from Ain Shams University Hospital were selected and assigned to group 1 (30 patients with LN) and group 2 (30 patients without LN). All patients were subjected to history taking, clinical examination, disease activity assessment based on SLE disease activity index (SLEDAI) and renal SLEDAI (SLEDAI-R) scores, and laboratory investigations, including as SUA, complete blood count, blood urea nitrogen (BUN), serum creatinine, creatinine clearance, urine analysis, protein/creatinine ratio, 24-h urinary protein excretion, Antinuclear antibodies (ANA), anti-dsDNA antibody, and serum complement (C3, C4). Results Disease duration, SLEDAI score, and SUA level were higher in group 1 than in group 2 (p < 0.001). SUA level was positively correlated with SLEDAI and SLEDAI-R scores, proteinuria, urinary casts, renal biopsy class, disease activity and chronicity indices, BUN level, and serum creatinine level but was negatively correlated with creatinine clearance (p < 0.05). SUA was a predictor of LN development in SLE patients (sensitivity, 83.3%; specificity, 70%). Conclusion SUA is associated with the development of lupus nephritis in patients with normal kidney function also SUA in-dependently correlated with disease activity and chronicity in LN.

Objective. Systemic lupus erythematosus (SLE) is an autoimmune disease identified by a plethora of production of autoantibodies. Autoreactive T cells may play an important role in the process. Attenuated T cell vaccination (TCV) has proven to benefit some autoimmune diseases by deleting or suppressing pathogenic T cells. However, clinical evidence for TCV in SLE is still limited. Therefore, this self-controlled study concentrates on the clinical effects of TCV on SLE patients. Methods. 16 patients were enrolled in the study; they accepted TCV regularly. SLEDAI, clinical symptoms, blood parameters including complements 3 and 4 levels, ANA, and anti-ds-DNA antibodies were tested. In addition, the side effects and drug usage were observed during the patients’ treatment and follow-up. Results. Remissions in clinical symptoms such as facial rash, vasculitis, and proteinuria were noted in most patients. There are also evident reductions in SLEDAI, anti-ds-DNA antibodies, and GC dose and increases in C3 and C4 levels, with no pathogenic side effects during treatment and follow-up. Conclusions. T cell vaccination is helpful in alleviating and regulating systemic lupus erythematosus manifestation.

Objective: Glycoprotein acetylation (GlycA) is a novel biomarker for chronic inflammation, associated to cardiovascular risk. Serum GlycA levels are increased in several inflammatory diseases, including systemic lupus erythematosus (SLE). We investigated the relevance of serum GlycA measurement in SLE and lupus nephritis (LN). Methods: GlycA was measured by NMR in 194 serum samples from patients and controls. Comparisons were performed between groups. Clinical and biological parameters were tested for correlation with GlycA levels. The predictive value of GlycA to differentiate proliferative from non-proliferative LN was determined using logistic regression models. Results: GlycA was correlated to C-reactive protein (CRP), neutrophil count, proteinuria and the SLE disease activity index (SLEDAI), and inversely with serum albumin. GlycA was higher in active (n=105) than in quiescent (n=39) SLE patients, in healthy controls (n=29), and in patients with non-lupus nephritis (n=21), despite a more altered renal function in the latter. In patients with biopsy-proven active LN, GlycA was higher in proliferative (n=32) than non-proliferative (n=11) LN, independent of renal function and proteinuria level. Logistic regression models showed that, in univariate models, GlycA outperforms traditional biomarkers. A bivariate model using GlycA and BMI better predicted the proliferative status of LN than a model comprising CRP, renal function (eGFR), serum albumin, proteinuria, C3 consumption and the presence of anti-dsDNA antibodies. Conclusion: Serum GlycA is elevated in SLE, and correlates with disease activity and LN. Serum GlycA, which summarizes different inflammatory processes, could be a valuable biomarker to discriminate proliferative from non-proliferative LN and should be tested in large, prospective cohorts.

Anti Phospholipid Syndrome

Chorea is a rare manifestation of systemic lupus erythematosus (SLE). We report on a young patient with chorea who was diagnosed initially with rheumatic fever. Follow up and further evaluation confirmed the diagnosis of SLE and anti-phospholipid syndrome. Of special interest were the negative antiphospholipid (aPL) antibodies and the initial diagnosis of rheumatic fever which is still not uncommon problem in our region. The rarity of such presentation with joint and non specific increase of antistreptolysin O (ASO) titer might be the factors that led to an incorrect diagnosis. Early diagnosis and treatment of SLE and anti-phospholipid syndrome are very crucial and should be considered with such presentation.
