Abstract
Predominant tubulointerstitial nephritis with negligible glomerular lesions is a rare form of lupus nephritis. Although tubulointerstitial changes occur in two-thirds of patients with lupus nephritis, these lesions were mostly accompanied by glomerulonephritis. Predominant tubulointerstitial lupus nephritis has been reported to be only 13 cases in the literature as far as we surveyed. Here, we present a case of a 72-year-old male who had pancytopenia associated with pernicious anemia and later developed a mild proteinuria and renal insufficiency. Although urinary tubulointerstitial markers increased, serological screening tests for tubulointerstitial nephritis were all negative. Three months later, the patient was diagnosed as systemic lupus erythematosus, based on polyarthritis, positive antinuclear antibody, immunological disorder and hematological disorder. Renal biopsy revealed severe infiltration of mononuclear cells in the interstitium with minimal abnormalities in glomeruli. Positive IgG and C1q staining with immunofluorescence antibody method in the tubular basement membrane and dense deposits in the same region with electron microscopy confirmed a diagnosis of predominant tubulointerstitial lupus nephritis. Since the patient's renal function declined rapidly, treatment with intravenous 500 mg methyl prednisolone followed by 40 mg/day of oral prednisolone was initiated. The patient's renal function improved and became stable even after tapering of prednisolone. Although lupus nephritis is generally accompanied by multiple symptoms such as fever, malaise, arthralgia, rashes, this case showed only pernicious anemia and tubulointerstitial nephritis initially.

Abstract
Background Organ-specific autoimmune diseases may appear in patients with systemic lupus erythematosus (SLE). Gastrointestinal symptoms are well documented in SLE and may be similar to those related to autoimmune gastrointestinal diseases. Objective Our aim was to search for gastrointestinal organ-specific autoantibodies in 194 patients with systemic lupus and 103 healthy controls from Southern Brazil. Methods Anti-endomysium antibodies (IgA-EmA), anti-gastric parietal cells (GPC) antibodies, anti-smooth muscle antibodies (ASMA), anti-mitochondrial antibodies (AMA) and anti-LKM-1 (liver-kidney microsomal) were searched for using indirect immunofluorescence in the sera of patients and controls. Results The total positivity of antibodies in SLE patients was 14.4% (28/194) and differed significantly from healthy individuals (0.97%; p < 0.001). IgA-EmA was more common in lupus patients than in controls (11/194; p = 0.009), and one of these patients had dermatitis herpetiformis. Clinical association revealed that IgA-EmA was more common in SLE patients with discoid lesions. The frequency of anti-GPC ( p = 0.10), ASMA ( p = 0.16) and AMA ( p = 0.55) did not differ significantly between groups. No patient presented LKM-1 autoantibodies. One patient presenting anti-GPC was diagnosed with atrophic gastritis and pernicious anemia. Conclusion Only IgA-EmA was significantly associated with lupus and with the presence of discoid lesions. Until now, no obvious association with celiac disease has been found.
