Calcinosis has long been associated with autoimmune disease and has a distinctive profile in scleroderma, dermatomyositis, systemic lupus erythematosus, and overlap syndromes. However, there have also been a number of case studies of calcific uremic arteriolopathy, or calciphylaxis, described within vessels, including patients with chronic renal insufficiency and several forms of vasculitis. Interestingly, the calciphylaxis associated with vasculitis appears to be unique, although relatively uncommon and is likely secondary to a disruption in the calcium-phosphate-parathyroid hormone axis. However, there appears to be an additional trigger, given that calciphylaxis is seen both in the absence of chronic kidney disease, and in the absence of a deranged calcium-phosphate-parathyroid hormone axis. These additional triggers include a high female predominance, obesity, diabetes and, possibly, warfarin use. In this review, we describe the clinical features of calciphylaxis, particularly in the context of autoimmune disease.

Although the kidney represents a major target organ in antiphospholipid syndrome (APS), renal involvement in APS was poorly recognized until recently. The most well-recognized renal manifestations of APS are the renal artery thrombosis/stenosis, renal infarction, hypertension, renal vein thrombosis, end-stage renal disease, increased allograft vascular thrombosis, some types of glomerular disease, and a small-vessel vaso-occlusive nephropathy, recently defined as APS nephropathy. APS nephropathy was first described in primary APS patients, characterized by acute thrombotic lesions in glomeruli and/or arterioles (thrombotic microangiopathy) and chronic vascular lesions such as fibrous intimal hyperplasia of arterioles and interlobular arteries, organized thrombi with or without recanalization, and fibrous arterial and arteriolar occlusions or focal cortical atrophy. APS nephropathy was also detected in further studies including patients with systemic lupus erythematosus (SLE)-related APS and SLE/non-APS patients with positive antiphospholipid antibodies, independently of lupus nephritis. The same histologic lesions, especially thrombotic mictroangiopathy, were also observed in patients with catastrophic APS. The most frequent clinical and laboratory characteristics of APS nephropathy in all the above groups of patients are hypertension (often severe), proteinuria (ranging from mild to nephrotic range), hematuria, and acute or chronic renal insufficiency.

Systemic lupus erythematosus, an autoimmune disorder which predominantly affects young women, is frequently complicated by renal involvement. Lupus nephritis (LN) is characterized by immune-complex mediated glomerular and tubulointerstitial inflammation Ieading to chronic renal insufficiency in up to 30% affected patients. In patients with suspected lupus nephritis, renal biopsy may be used to confirm the diagnosis and determine appropriate therapy. The ISN/RPS classification of LN represents a significant advance over the 1982 WHO scheme. The treatment of lupus nephritis often consists of a period of intensive immunosuppressive therapy (induction therapy) followed by a period of less intensive maintenance therapy. The established treatment of lupus nephritis with cyclophosphamide and steroids has improved the outcome of LN but is burdened with significant adverse effects. Results of clinical studies showed that mycophenolate mofetil is equally effective with fewer toxic complications than standard therapy, but its long-term efficacy is not yet known. New therapeutic agents (biologic drugs) targeted to the pathogenetic mechanism of the disease are promissing improved efficacy with less toxicity. Despite recent advances, treatment of lupus nephritis remains a challenging clinical problem.

A 57-year-old female patient with a history of tophaceous gout based on chronic renal insufficiency caused by systemic lupus erythematosus nephritis developed bursitis of the right lateral malleolus. This was taken for gout and was treated with colchicine and an increased dose of her maintenance therapy of oral glucocorticoids. Since this had no effect, a local diagnostic puncture was performed. Aspiration yielded pus from which Staphylococcus aureus was cultured; upon polarisation microscopy many uric acid crystals were seen. The diagnosis was gout and coincident bacterial infection. Therapy consisted of incision of the bursa and antibiotic therapy. Local recovery was uneventful. In patients suspected of an acute gout attack who have an increased risk of bacterial infection, e.g. elderly and patients with severe comorbidity or immunodeficiency, a local diagnostic aspiration is the only adequate investigation. Only if (coincident) bacterial infection has been ruled out, patients with contraindications for non-steroidal anti-inflammatory drug therapy and colchicine may safely be treated for a gout attack with oral glucocorticoids.

Renal involvement can be a serious problem for patients with antiphospholipid syndrome (APS). However, this complication has been poorly recognized and studied. It can be present in patients who have either primary or systemic lupus erythematosus-associated APS. Clinical and laboratory features of renal involvement in APS include hypertension, hematuria, acute renal failure, and progressive chronic renal insufficiency with mild levels of proteinuria that can progress to nephrotic-range proteinuria. The main lesions are renal artery stenosis, venous renal thrombosis, and glomerular lesions (APS nephropathy) that may be acute (thrombotic microangiopathy) and/or chronic (arteriosclerosis, arterial fibrous intimal hyperplasia, tubular thyroidization, arteriolar occlusions, and focal cortical atrophy). APS can also cause end-stage renal disease and allograft vascular thrombosis. This article reviews the range of renal abnormalities associated with APS, and their diagnosis and treatment options.

The authors present a case report of a 39-year-old woman with acute abdomen - a comorbid patient with systemic lupus erythematosus, chronic renal insufficiency as a complication of lupus nephritis, included in a haemodialysis programme. The patient had also undergone transplantation of the left kidney in the past. She was initially admitted to the Department of Traumatology for a total endoprosthesis procedure due to bionecrosis of the head of the thigh bone. Postoperatively, the patients condition was complicated by gangrene of the colon confirmed by CT scan and during the operation. The patient was operated on - subtotal colectomy, terminal ileostomy and left-sided ovariectomy was performed. The postoperative course was complicated by perforation of the jejunum which was sutured. The patient was admitted to ICU and, after recovery, to our surgical department. Because of the metabolic disturbance she was treated in the internal medicine department. After 60 days she was discharged in a good condition, walking and with full per os realimentation.Key words: lupus erythematosus gangrene of the colon acute abdomen.

C1q nephropathy is considered a form of glomerulonephritis, defined by histological findings of dominant Clq immune deposits in renal biopsy. It is a rare disease, most often manifested in children and young adults. The most common clinical manifestation of the disease is nephrotic syndrome, but other renal syndromes could also be found. The cause of the disease is not known, but the immune pathogenesis could be assumed. Often, resistance to glucocorticoid or other immunosuppressive therapy is present, potentially leading to chronic renal insufficiency. We present ten patients with renal biopsy and clinical findings of Clq nephropathy. None of the patients had clinical or serological manifestations of systemic lupus. All patients had normal findings of C3 and C4 components of complement, as well as normal ANF, anti-dsD-NA and ANCA antibodies.
