Analysis is carried out of the clinical, pathomorphological and immunological characteristic of lupus nephropathy in 62 patients, 56 females and 6 males. A series of new investigation methods were used for that purpose. An early tendency towards kidney involvement in the course of LED is established and in 22 of the patients (36%) the renal symptoms have been the first clinical manifestations of the basic illness. Lupus nephropathy progresses most often with a nephrosis syndrome (in 66.1% of the patients), rarely pure and not combined with hypertension and/or with renal insufficiency. The pathomorphological changes are rather multiform but in the majority of the cases almost all structural elements of glomerules and the rest of the renal tissue are affected. The clinical picture severity, histopathological changes and nephropathy evolution course were established to be distinctly dependent on the course acuteness of the basic morbid process. The importance of the detailed study of the clinico-morphological and immune characteristic of lupus nephropathy upon the timely diagnosis. Proper treatment and the prognosis assessment of the illness is stressed upon.

Human TNF alpha locus locates between HLA-B and DR region on the short arm of chromosome 6. The 5.5 kb and 10.5 kb of TNF alpha restriction fragment length polymorphic (RFLP) bands were identified by Southern hybridization using a restriction enzyme, NcoI. The frequencies of those bands were not different among patients with systemic lupus erythematosus (SLE), those with rheumatoid arthritis and normal controls. In the lupus patients, proteinuria was more frequent in the patients with the 5.5 kb RFLP band (19/39: 48.7%) than those without 5.5 kb band (7/35: 20%) (p less than 0.05). Furthermore, this band was strongly associated with the haplotype HLA B44-DRw13-DQw1. In order to investigate the association between this gene polymorphism and the production of TNF alpha, peripheral blood mononuclear cells from patients with SLE and normal controls were cultured for 24 hours with lipopolysaccharide and concanavalin A and the amount of TNF alpha in the supernatant was measured by enzyme linked immunosorbent assay. The TNF alpha production of lupus patients was not statistically different from that of normal controls. The production of TNF alpha was not related to 5.5 kb RFLP band, but in the patients with SLE, the mean value of TNF alpha in patients with the 5.5 kb RFLP band tended to be higher than those without the band. Lupus patients were divided into two groups by the production of TNF alpha i.e. low TNF alpha inducibility group and high TNF alpha inducibility group. Patients with proteinuria were more frequent in patients of the high TNF alpha inducibility group than those of low TNF alpha inducibility group (p less than 0.05). There were four patients with HLA B44-DRw13-DQw1 who had the 5.5 kb RFLP band and three of them belonged to the high TNF alpha inducibility group with nephrosis. These data suggest that TNF alpha and HLA are possibly associated with the severity of lupus nephritis.

Samples of protein from the urine of 23 patients with lupus nephropathy and 15 patients with proteinuria who did not have systemic lupus erythematosus (SLE) were studied for the presence of cytokines, soluble interleukin 2 receptors (sIL-2R), and free light chain immunoglobulins. The patients with lupus nephropathy were divided into two groups with active (nephritis) and inactive inflammation (nephrosis) based on the results of the analysis of urine samples and renal histology. The crude urine proteins (5 mg/ml) after precipitation by 80% ammonium sulphate from 14 patients with lupus nephritis contained higher concentrations of sIL-2R (4.88 (SEM 1.27 ng/ml) than those from nine patients with nephrosis (1.11 (0.52) ng/ml) or 15 patients without SLE (1.31 (0.87) ng/ml). The concentration of sIL-2R in protein from urine samples was not correlated with the concentration in plasma and was inversely correlated with the excretion of protein in urine over 24 hours in patients with SLE. It is suggested that, in addition to leakage from the circulation, the local production of sIL-2R by inflamed kidneys is possible. The crude proteins in urine were further fractionated by gel filtration on Sephacryl S-200. Arbitrarily, four fractions could be obtained from urine from patients with SLE but only three fractions were found in the urine of patients without SLE. Fraction IV derived from patients with nephritis or nephrosis augmented the pokeweed mitogen induced [3H]thymidine uptake of mononuclear cells. In addition, the positive rates of free kappa (kappa) (35.7%) and lambda (lambda) (42.9%) chains in proteins in urine from nephritic patients were higher than those in the other two groups. These results suggest that the severity of inflammation in the kidneys of patients with lupus can be reflected by the increased excretion of sIL-2R, free light chain immunoglobulins, and cytokine-like molecules in urine.

MHC class I and II molecules serve as restriction elements for the presentation of antigen-specific T cell reactions and may be implicated in the process of cellular transformation. We have analysed the expression of MHC class I and II antigens including the associated invariant gamma-chain in 100 consecutive renal biopsies by a sensitive immunoperoxidase method using monoclonal antibodies against HLA-ABC, HLA-DR, HLA-DQ, HLA-DP and the invariant gamma-chain (Ii). HLA-ABC was expressed by almost all parenchymal cells except for podocytes. Staining for HLA-DR was found consistently in glomerular and interstitial capillary endothelial cells, in "dendritic" (LCA positive) and most infiltrating interstitial cells but not in mesangial and most extracapillary cells. Similar but weaker positivity was observed for HLA-DQ and -DP. HLA-DR positive infiltrating mononuclear cells in glomeruli were noted in acute glomerulonephritis (GN) and Lupus GN associated with enhanced staining of endothelial cells. In addition, HLA-DR was uniformly or focally expressed by predominantly proximal tubules in 80% of biopsies, especially IgA-GN, focal glomerulosclerosis, acute GN but also in 54% of cases with minimal change nephrosis. HLA-DP and -DQ were only positive in a limited number of HLA-DR positive tubules. The expression of the invariant gamma-chain was comparable with the reactivity for HLA-DR. In addition, all HLA-DR-positive tubules expressed the invariant gamma-chain. Subtyping of T cells in biopsies with DR-positive tubules and interstitial infiltrates (n = 20) showed a predominance of CD 4 positive cells in the majority of cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Authors studied the dispersion of immunoreactive HSPG with monoclonal antibody specific to protein nucleus of HSPG in renal diseases associated with nephrosis syndrome. Their results showed that the dispersion of HSPG in GBM does not fully agree with dispersion of anion linkage places known in literature. In membrane and diffuse proliferative lupus glomerulonephritis immunoreactive HSPG cannot be demonstrated in the place of immune deposits, concurrent with dispersion of anion places, while it appears in GBM newly developed round the deposits. Inconsistent with this, in glomerulonephritis having minimal changes, the anion loss of GBM is not associated with absence of nuclear protein, the immunoreactive HSPG remains intact. These observations reflected in literature indicate that--similarly to proteinuria--presumably, deficiency of anion linkage places of GBM is caused by different pathomechanisms.

Thrombosis occurs when there is a breakdown in the balance between thrombogenic factors and protective mechanisms. The thrombogenic factors may be exogenous (e.g. trauma, surgery), endogenous (e.g. cancer, vascular diseases) or both (e.g. atherosclerosis, complicated pregnancy). Defects in the protective mechanisms may be congenital (e.g. factor V R506Q-mutation, deficiency of protein C, protein S or antithrombin) or acquired (e.g. lupus anticoagulans, deficiency of antithrombin in nephrosis). In recent years, research in thromboembolic diseases has been overwhelmed with new observations, rendering it worthwhile to put efforts into the evaluation of thrombotic mechanisms in individuals suffering from or predisposed to thromboembolic diseases. Such efforts will pave the way for more effective prophylaxis in thrombosis-prone patients, more specific treatment of thrombotic diseases, and the mastering of recurrent thrombosis.

Systemic lupus erythematosus (SLE), a disorder of the immune system, is potentially curable by allogeneic bone marrow transplantation (alloBMT). Until recently, alloBMT was limited by donor availability and toxicity. Reduced intensity conditioning (RIC) combined with post-transplantation cyclophosphamide (PTCy) has improved the availability and safety of alloBMT permitting its exploration in severe-refractory autoimmune illnesses. We report the six-year follow-up of a young female whose refractory SLE-associated nephrosis resolved after RIC alloBMT with PTCy.
