A 36-year-old man with ankylosing spondylitis, amyloidosis and chronic renal failure on maintenance hemodialysis developed severe hypoglycemia while being treated with propoxyphene. Upon discontinuation of the drug blood glucose levels returned to normal and hypoglycemia did not recur. Simultaneously with hypoglycemia, plasma glucagon and growth hormone levels were appropriately raised and serum insulin levels were adequately suppressed, thus ruling out hyperinsulinemia as the cause of hypoglycemia. A review of the literature disclosed four similar cases of propoxyphene-induced hypoglycemia, two of them with renal dysfunction. Propoxyphene should be remembered as a potential cause of hypoglycemia, particularly in patients with renal failure.

The authors have studied 6 cases of systemic AA amyloidosis associated with ankylosing spondylitis. Renal failure occurred in all patients a mean of 19 years after the clinical onset of the rheumatic disease. Three patients progressed rapidly (between 3 months and 3 years) to end-stage renal failure. Such an outcome did not depend upon early onset of the renal impairment, degree of inflammation or treatment with colchicine. All patients were alive 2 to 10 years later, and this confirms a better prognosis than with AL amyloidosis. The utility of combining Wright's permaganate reaction with immunological methods to characterize the amyloid deposits was also confirmed. It is concluded that amyloidosis is a rare complication of ankylosing spondylitis and probably depends on a genetic predisposition. The possibility of amyloidosis should be kept in mind when proteinuria or renal failure appear in the course of ankylosing spondylitis.

Infusions of corticosteroids in massive doses (methylprednisolone 1 g/day for 1 to 3 days) are used by nephrologists against acute episodes of rejection of transplanted kidneys and in acute glomeruloneppritis , especially lupic , with threatening renal failure. During the last few years this method has been tried in collagen diseases, notably in acute episodes of systemic lupus erythematosus without renal insufficiency, in rheumatoid arthritis and in ankylosing spondylitis. Published controlled studies concerning these three diseases are too few for firm conclusions to be drawn. The improvement obtained during 3 months on average after 3 g (1 g/day for 3 days) is not observed in all patients and it is not certain that such high doses are innocuous: they do not seem to have been responsible for deaths, as reported in patients with renal transplantation, but undesirable side-effects are observed in one-half of the cases. Close supervision with repeated measurement of blood electrolytes and electrocardiograms is mandatory during and immediately after treatment.

Eleven patients with amyloidosis were treated for terminal renal failure by transplantation, receiving 12 cadaver allografts. In one patient the amyloidosis was primary and in the remaining 10 it was secondary to a chronic inflammatory disease. All of the patients were subjected to one or two fine-needle aspiration biopsies of the kidney graft during a followup of 11 to 68 months. The biopsies of three patients, one with primary amyloidosis and two with ankylosing spondylitis, revealed amyloid recurrence in the graft. These recurrences were diagnosed at 11, 28, or 37 months, respectively. The risk of amyloid recurrence is thus by no means negligible. The present study revealed no factors determining the development of recurrence. In two additional cases, membranous glomerulonephritis was observed in transplant biopsy. Both of these patients had rheumatoid arthritis as the underlying disease and were treated with gold salts before transplantation. It is suggested that an impaired immune response, related to amyloidosis and/or immunosuppressive therapy, may have favored the formation and deposition of circulating immune complexes.

The aim of this retrospective study was to characterise the clinical presentation and disease associations of Oriental patients with gout seen in our hospital over a six-month period. One hundred patients comprising of 77 males and 23 females [89% Chinese, 7% Malays, 2% Indians and 2% others; mean age was 50.9 years (range 18 to 82 years), mean age at onset of disease was 43.7 years (range 16 to 78 years)] were studied. The disease was familial in 18% and 44% of patients had a history of alcohol ingestion. Co-morbid conditions included hypertension (36%), hyperlipidaemia (25%), renal failure (17%), ischaemic heart disease (13%), diabetes mellitus (4%), systemic lupus erythematosus (3%), psoriasis (2%) and ankylosing spondylitis (1%). The majority of patients (68%) had at least one associated disease. At the onset of disease, the joints commonly involved were the ankles (39%) and knees (27%) whilst the first metatarsophalangeal (MTP) joint was affected in only 26% of cases. Polyarticular onset was uncommon (n = 6). The precipitating factors reported by the patients included food (n = 23), alcohol (n = 12), drugs (n = 4), trauma (n = 3) and surgery (n = 2). Eleven patients had a history of renal calculi and 15% had tophaceous gout. Majority of patients (71%) had been treated with urate-lowering drugs (allopurinol). We concluded that gout in Singapore predominantly affects middle-aged men who often have an accompanying illness.

There is a paucity of randomized, controlled therapy studies of the extraintestinal manifestations of inflammatory bowel disease (IBD). Most current therapeutic approaches are empiric or based on approaches to therapy in other settings. In the past year anecdotal evidence has emerged for the use of therapies that neutralize tumor necrosis factor-a in both ankylosing spondylitis and the dermatologic extraintestinal manifestations. Topical tacrolimus has also emerged as a potentially useful therapy for dermatologic manifestations. Finally, patients with IBD occasionally become transplant recipients. One study reported worsening IBD after orthotopic liver transplantation for primary sclerosing cholangitis, and another reported the benefit of renal transplantation in amyloidosis-induced renal failure.

The prevelance of ankylosing spondylitis or sacroiliitis in Behcet's disease has been the subject of debate for some time. Two cases with atypical presentation and course are discussed. The first patient was a young woman with Behcet's disease whose primary complaint was neck pain. X-ray examination showed severe cervical involvement, characteristic of the type seen in women with ankylosing spondylitis. She subsequently developed anterior uveitis. The second patient was a man suffering from back pain and limited movement of his neck and back. When he was referred to our outpatient clinic, his severe anemia became the subject of the whole investigation. He was diagnosed with Behcet's disease with ankylosing spondylitis accompanied with amyloidosis and an end-stage renal failure.

Amyloidosis is a systemic disorder characterized by the extracellular tissue deposition of insoluble, toxic aggregates in bundles of beta-sheet fibrillar proteins. These deposits are typically identified on the bases of their apple-green birrefringence under a polarized light microscope after staining with Congo red, and by the presence of rigid, nonbranching fibrils 8 to 10 nm in diameter on electron microscopy. The type of amyloid fibril unit can be further defined by immunohistology or by immunoelectron microscopy. It has been described at least 25 different human protein precursors of amyloid fibrils, which will describe its corresponding amyloid disease. The most common types of amyloidosis are AL (primary) and AA (secondary) types; the former, is the most frequent and is due to deposition of proteins derived from immunoglobulin light chain fragments, occurring alone or in association with multiple myeloma. The later (AA), is caused by deposition of fibrils composed of fragments of the acute phase reactant serum amyloid A (SAA) and complicates chronic diseases with ongoing or recurring inflammation, namely; rheumatoid arthritis (RA), juvenile chronic polyarthritis, ankylosing spondylitis, familial periodic fever syndromes (Familial Mediterranean Fever), chronic infections and furthermore, some neoplasms (mainly renal cell carcinoma and Hodgkin's disease). Despite its less frequent association, some benign neoplasms can subsequently complicate to AA amyloidosis, therefore, an early diagnose and successful treatment may lead indeed, to regression of the amyloid disease. Herein, we present two cases of AA amyloidosis, both of them caused by 2 different benign neoplasms: 1. A 34 year-old woman, after chronic oral contraceptive use, developed an hepatic adenoma (fig. 1) which finally lead to AA amyloidosis with primary kidney presentation (pure nephrotic syndrome) (table 1). Post-surgical complications yield to acute renal failure from which unfortunately could not be recovered. After being on hemodialysis therapy during 10 months she received a first renal allograft without any complication. 2. A 20 year old woman, was diagnosed of AA amyloidosis after a renal biopsy (fig. 2) because of nephrotic syndrome (table 1). Further investigation lead to the finding of a hialyne-vascular type Castleman's disease located in the retroperitoneum (fig. 2). Despite surgical resection and medical treatment (colchicine) she developed progressive renal failure requiring initialization of hemodialysis therapy. After 6 years being on hemodialysis, she received a first renal allograft which is currently functioning after one year of follow- up. Although other chronic inflammatory diseases complicate more frequently to AA amyloidosis, benign tumors have to be taken into account as a potential ethiological cause for secondary amyloidosis.

Infliximab is a chimeric monoclonal antibody to TNF-alpha which acts on both the soluble and transmembrane forms of TNF-alpha. It has been used successfully for the treatment of psoriasis and psoriatic arthritis, rheumatoid arthritis, Crohn's disease and ankylosing spondylitis either as monotherapy or in combination with drugs such as methotrexate. To date, over 20,440 patients with moderate-to-severe psoriasis have been treated with infliximab worldwide. Opportunistic infections and reactivation of underlying latent infections are an area of concern with the use of infliximab particularly when used in conjunction with other immunosuppresants. The authors report a case of histoplasmosis presenting with signs of severe hypercalcemia and renal failure in a patient on infliximab for approximately three years in combination with low dosages of methotrexate and prednisone. This report stresses the importance of maintaining a high index of suspicion for unusual pathogens while managing patients receiving TNF-alpha inhibitors, particularly when used in combination with other immunosuppressants. In addition, the authors emphasize the role of a multi-disciplinary approach and appropriate coordination among caregivers.
