An idiopathic nephrotic syndrome associated with membranous glomerulopathy antedated the subsequent emergence of systemic lupus erythematosus in two patients (7-year-old and 14-year-old girls). At the onset of INS, there was neither clinical evidence of multisystem disease nor unequivocal serologic evidence of SLE. The only early possible indication of SLE was the presence of microtubular inclusions in glomerular endothelial cells on electron microscopy. In each instance (one year and three years after onset of INS), a second renal biopsy showed transformation of the membranous glomerular lesion to a more florid type with glomerular subendothelial dense deposits. One patient died of overwhelming pulmonary infection while she was receiving prednisone and cyclophosphamide; the other developed progressive renal failure despite steroid treatment. SLE should be considered in patients presenting with apparent idiopathic MG, in whom nephrotic syndrome persists. Intraendothelial cell microtubular inclusions may be an early clue to later emergence of SLE.

The gene responsible for the lpr mutation in MRL mice that are prone to systemic lupus erythematosus has been shown to encode the apoptosis-inducing Fas antigen, thus pointing to control of apoptosis as a major regulatory mechanism in autoimmunity. In the non-obese diabetic mouse model for insulin-dependent diabetes, four non-MHC-linked loci have been localized in the murine genome that were found to be associated with successive stages of the disease. These findings should soon have a major impact on our understanding of human autoimmune diseases.

Patients with systemic lupus erythematosus (SLE), systemic scleroderma (SSD) and donors were examined for the blood levels of adrenocorticotropic hormone, hydrocortisone, follicle-stimulating hormone, luteinizing hormone, prolactin, estradiol, testosterone, progesterone, thyroid-stimulating hormone, triiodothyronine, thyroxin, and insulin. The corticotropin load test was carried out in 38 SLE patients, 32 SSD patients and 24 donors. The prednisolone test was made in 15 SSD patients and 27 donors. The studies were made with the aid of RIA. The patients with SLE manifested a decline of the basal level of hydrocortisone as well as a reduction of the reserve potentialities of the pituitary-adrenal system. The patients with SSD demonstrated a negligible decrease of the basal level of hydrocortisone with an evident lowering of the reserves of the same system. The treatment of SLE and SSD patients with glucocorticoids was followed by marked hyperinsulinemia.

A role for heat shock proteins (HSPs) in autoimmunity has recently been suggested by several authors. Autoantibodies against HSPs have been associated with such autoimmune diseases as systemic lupus erythematosus, polymyositis, and the NOD mouse model of diabetes. Moreover, genes for the major 70,000-M(r) HSP (HSP70) are located within the MHC. To investigate a potential association of an HSP70-2 gene polymorphism with insulin-dependent diabetes mellitus (IDDM), we analyzed restriction-fragment-length polymorphism (RFLP) of this gene in 29 families with one or more member affected by IDDM. With the enzyme PstI, as reported previously, two HSP70-2 alleles of 8.5- and 9.0-kb were found. The 8.5-kb allele was found more frequently on diabetic haplotypes compared with control haplotypes (41 of 66 [62%] vs. 20 of 46 [43%], P = 0.03). This association was due to the conservation of alleles on extended haplotypes we previously reported to be associated with diabetes on initial analysis of families. Twenty-three of 26 diabetic DR3 haplotypes and 3 of 3 normal DR3 haplotypes and all instances of [HLA-B8, SC01, DR3] and [HLA-B18, F1C30, DR3] had the 8.5-kb allele, whereas 0 of 9 normal DR2 haplotypes and 0 of 2 diabetic DR2 haplotypes had the 8.5-kb allele (P = 8 x 10(-7) DR3 vs. DR2 haplotypes). The alleles were equally distributed among DR4 haplotypes.(ABSTRACT TRUNCATED AT 250 WORDS)

From June 1987 to June 1991 at the Belgrade University Children's Hospital 10 patients, 5 males and 4 females, aged 2-16 years, with chronic glomerular disease, were treated with CyA. Seven patients had INS, 2 lupus nephritis and one IgA nephritis. Before initiation of CyA, all but one, were treated with classic immunosuppressive therapy, which had no effect (8/10) and/or had serious adverse effects (9/10). CyA dosage was initiated at 4-6 mg/kg/BW, and was subsequently adjusted to achieve CyA concentrations in blood at range 50-100 ng/ml. Treatment duration was 2-17 months. Patient compliance to CyA therapy was observed in 5/7 INSs: 2 cortico-sensitive (1 with FSGS was cortico-dependent and 1 had frequent relapses) and 3 cortico-resistant patients (2 with FSGS and 1 with minimal histologic changes). After drug withdrawal, only one of the patients who responded, had no relapse. One of the two patients with SLE showed improvement during CyA administration, while no response was observed in the patient with IgA nephritis. Adverse experiences with CyA therapy involved decreased renal function (2/10), arterial hypertension (1/10), hyperbilirubinaemia (1/10), transient LDH increase and hyperuricaemia (1/10).

Insulin antibodies (IAA) can be detected in the serum of the majority of newly diagnosed IDDM patients prior to insulin therapy. In first degree relatives of IDDM patients, IAA are associated with an increased risk of development of IDDM. However, the disease specificity of IAA, detected by radiobinding assays, has not been addressed. We thus tested sera from patients with autoimmune disease for IAA. One of 29 (3%) patients with Graves' disease and five of 27 (19%) patients with SLE had IAA levels exceeding the range for normal controls. IAA were not detected in sera from 29 patients with Addison's disease, 15 patients with pernicious anaemia or 10 patients with increased gamma globulins. Non-specific binding of 125I-labelled insulin was increased in serum from 14 (21%) samples from patients with Graves' disease, 10 (37%) patients with SLE, one (3.2%) of 29 patients with Addison's disease and two (13%) of 15 patients with pernicious anaemia. The increased non-specific binding most likely relates to immunoglobulin binding as it was also found in eight of 10 patients with oligoclonal or polyclonal increase in gamma globulins. Our findings suggest that moderate elevations of IAA are not uncommon in patients with SLE, in whom increased non-specific binding of insulin is also common. This observation is of importance in preclinical diabetes screening studies.

A novel TaqI restriction fragment length polymorphism (RFLP) of 4.15 kb is reported using a DR beta probe (pRTV1). This fragment corresponds to the DRB1 locus and allows the subdivision at the DNA level of the DRB1*0301 allele (DR3 antigen), which had not previously been reported. Both splits also distinguish each of the two DR3-bearing extended haplotypes (HLA-B8,SCO1,DR3,DQw2,Dw24 and B18,F1C30,DR3,DQw2,Dw25) found associated to several autoimmune diseases as insulin-dependent diabetes mellitus (IDDM), systemic lupus erythematosus (SLE) and myasthenia gravis. The fact that no polymorphism in the DRB1*0301 coding DNA sequence has been detected indicates that DRB1*0301 intronic, regulatory of neighbouring sequences might also contribute to differential disease associations (and pathogenic mechanisms) found linked to each of the two DR3-bearing haplotypes, i.e. IDDM and B8,DR3,Dw24 in North European/American Caucasoids vs IDDM and B18,DR3,Dw25 in Mediterraneans; SLE and B8,DR3,Dw24 in children vs SLE and B18,DR3,Dw25 in Spanish adults.

The nonobese diabetic (NOD) mouse, in which major histocompatibility complex genes may be involved in the susceptibility to diabetes, has been developed as a model of autoimmune diabetes. The NOD mouse expresses I-A-encoded class II major histocompatibility complex antigens, which differ from those of other mouse haplotypes by the presence of a serine at position 57 of the A beta chain. Identifying islet autoantigens may help elucidate the role of class II antigens in the activation of autoreactive T cells and, thus, in the development of diabetes. We have detected autoantibodies directed against a 58-kDa islet cell antigen in NOD mice but not in other strains, including lupus-prone mice. Apart from insulin-secreting cells, the 58-kDa antigen was only found to be expressed by neuroblastoma cells and was identified as peripherin, an intermediate filament protein previously characterized in well-defined neuronal populations. This autoantigen cross-reacted with I-Anod class II antigens, suggesting that it may contribute to defective self-tolerance of islet beta cells in the NOD mouse.

Only a few immunosuppressive drugs can be used today. These are: corticosteroids, azathioprine, cyclophosphamide, ciclosporine A, accessorily chlorambucil and methotrexate. They all have different actions on immune responses. The use of these drugs has completely changed the prognosis of autoimmune diseases such as systematic lupus erythematous, polyartheritis nodosa, Wegener's granulomatosis. Nevertheless treatment of other autoimmune diseases, such as type I insulin-dependent diabetes mellitus or multiple sclerosis, has been inconclusive.
