Two patients (one male, one female) with ankylosing spondylitis (AS) and IgA nephropathy are described. The female patient is the first reported case to have AS and IgA nephropathy concurrently. Contrary to previously reported cases, her renal manifestation preceded her rheumatic symptoms. It is suggested that women with IgA nephropathy and AS may be overlooked as the severity of spondylitis and joint involvement is less than in men.

We describe 2 patients with immunoglobulin A (IgA) nephropathy in association with ankylosing spondylitis. Renal biopsy demonstrated mesangial proliferative glomerulonephritis with prominent IgA, C3c, and less intense properdin deposition in the glomeruli. Intraglomerular clumps of virus-like particles were also observed in the kidney sample from one patient (case 2), who had an abnormal liver function. Our findings support the hypothesis that here is a possible common pathogenesis responsible for the concurrence of both IgA nephropathy and ankylosing spondylitis.

Cutaneous immunofluorescence studies were carried out in 21 patients with ankylosing spondylitis (AS) and the results compared with those for 18 healthy subjects. The most prominent finding was the presence of IgA in dermal vessels of patients with AS (71% compared with 17% of the control group). IgG and IgM cutaneous deposits were also observed in patients with AS, but these results did not differ from those of the control group. A renal biopsy was performed in three of the patients presenting with unexplained microscopic haematuria. One of them had an IgA nephropathy, but no correlation was found between kidney and skin deposits of IgA. These findings suggest that IgA cutaneous deposits in AS are not a marker of IgA nephropathy but stress the role of immunoglobulin A in the pathogenesis of this disease.

Immunoglobulin synthesis by peripheral blood lymphocytes and serum IgA subclasses were investigated in patients with ankylosing spondylitis (AS) with and without accompanying microscopic hematuria, and HLA-B27 positive and negative healthy controls. An increase in serum IgA, restricted to subclass IgA1, was found in patients with AS, especially in those with microscopic hematuria. IgA synthesis was not increased, but a significant shift to subclass IgA1 was found. Our results resemble abnormalities previously noted in primary IgA nephropathy, and further support the pathogenetic role of IgA in AS.

Ankylosing spondylitis (AS) is associated with IgA nephropathy. To study the pathogenetic mechanism of this association the presence of haematuria and circulating IgA containing immune complexes (IgA ICs) in 70 patients with AS was determined. In this retrospective study haematuria was present in 15 patients and 25 patients had IgA ICs. Circulating IgA ICs were shown in 9/15 (60%) of the patients with haematuria and in 16/55 (29%) of those without haematuria. These results suggest that IgA ICs in patients with ankylosing spondylitis have a pathogenetic role in causing IgA nephropathy.

There have been a few reports suggesting the association between glomerulonephritis (GN) and ankylosing spondylitis (AS). The reported glomerulonephritides include IgA nephropathy, mesangial proliferative GN and membranous nephropathy. From January 1983, through December 1984, we observed 5 cases of GN among 116 cases of definite AS. Three of them were IgA nephropathy. The other two were mesangial proliferative GN, with IgM deposit in one case and isolated C3 deposit in another. Microscopic hematuria was observed in all of them. The renal function and 24-hour urine protein excretion were all within normal limits. Serum IgA level increased in all but the case of mesangial proliferative GN with IgM deposit. All except one had the antigen of HLA-B27. Serum IgA level was determined in 78 cases (86 estimations) of AS. The mean value was 399.6 +/- 15.0 mg/dl (mean +/- SE) (normal range: 100-350 mg/dl). Fifty-four of them (63%) had a value higher than 350 mg/dl. The interrelationship of AS and IgA nephropathy was discussed.

In 40 patients with ankylosing spondylitis (AS) no evidence for IgA nephropathy was obtained. This conclusion was based on the absence of hematuria and on the inability to find an increased incidence of IgA-containing immunoglobulin deposits in skin biopsies. Increased Clq binding assay was only found in those AS patients with anterior uveitis. In 26% of the skin biopsies perivascular mononuclear cell infiltrates were observed, and immunoglobulin deposits were seen in 65%. These facts suggest that the immunologic system is involved in the pathogenesis of this disease.

2 patients with ankylosing spondylitis (A Sp) were found to have renal lesions similar to those seen in IgA nephropathy. In 1 patient the changes were extremely severe and progressive and in the other they were mild. Vascular changes were also noted in 1 patient. The findings suggest an immune complex mediated glomerulonephritis and support an earlier report that there may be a specific renal lesion in patients with A Sp. The significance of IgA deposition in the mesangium, and of an increase in the serum levels of IgA in some patients with A Sp is unclear.

A retrospective analysis of our patients with ankylosing spondylitis revealed a 17.8% incidence of recurrent hematuria. Two of the five patients with recurrent hematuria had previously undergone renal biopsies showing a focal proliferative glomerulonephritis. The only specimen examined by immunofluorescent staining showed the typical changes of IgA nephropathy. A control group of patients with rheumatoid arthritis did not show recurrent hematuria. Recurrent hematuria may be a frequent occurrence in ankylosing spondylitis and may signify the presence of one of the glomerulonephritides such as IgA nephropathy.

We describe a patient with ankylosing spondylitis and psoriasis who was found to have IgA nephropathy in a solitary kidney. Renal biopsy demonstrated mesangial proliferation and interstitial nephritis with mesangial deposition of IgA. Although the renal disease and the rheumatic disease could have been present together by chance association, evidence is presented to suggest a possible common pathogenesis.
