Longterm drug therapy for rheumatoid arthritis in seven rheumatology private practices: I. Nonsteroidal antiinflammatory drugs.

The probability of continuation of a particular nonsteroidal antiinflammatory drug (NSAID) over 5 years was estimated for 1,775 courses taken by 532 patients with rheumatoid arthritis treated in 7 rheumatology private practices. Similar results were seen for 15 different NSAID--48% of courses were continued at 12 months, 36% at 24 months, and 20% at 60 months. Only acetylated salicylates, other than plain aspirin, were continued significantly longer than any of the other NSAID. The probability of continuation of plain aspirin was similar to other NSAID, including nonacetylated salicylates and nonsalicylate NSAID. The first NSAID taken by an individual patient was continued only marginally longer than the 4th NSAID taken by the same patient. While most NSAID courses were not continued for long periods, 20% were continued for longer than 5 years, suggesting effective longterm results in this minority of courses.

Gonococcal pericarditis with tamponade in a patient with systemic lupus erythematosus.

Pericarditis is one of the most frequent manifestations of systemic lupus erythematosus; however, purulent pericarditis and tamponade are rare. We describe a patient with systemic lupus erythematosus and culture-proven gonococcal arthritis who developed purulent pericarditis with intracellular gram-negative diplococci. Evidence of tamponade was seen on echocardiography. There has not been a reported case of Neisseria gonorrhoeae in pericardial fluid or tissue since the introduction of antibiotics.

Subacute cutaneous lupus erythematosus during PUVA therapy for psoriasis: case report and review of the literature.

Lesions typical of subacute cutaneous lupus erythematosus developed in an elderly woman after 6 months of PUVA (8-methoxypsoralen and longwave ultraviolet light) therapy for psoriasis. Pancytopenia, antibodies to double-stranded DNA, and hypocomplementemia developed concurrently with the appearance of the cutaneous lesions. With discontinuation of photochemotherapy, the cutaneous lesions disappeared and the pancytopenia improved.

Necrotizing systemic vasculitis with features of both Wegener's granulomatosis and Churg-Strauss vasculitis.

We describe a patient who had nasal biopsy-demonstrated eosinophilic vasculitis and renal biopsy-demonstrated necrotizing glomerulonephritis with tissue eosinophilia. Despite corticosteroid therapy, the patient's renal function deteriorated, and nodular pulmonary infiltrates developed. Both conditions responded dramatically when cyclophosphamide was added to the treatment regimen. The renal disease activity was monitored with the aid of cytodiagnostic urinalysis, a technique of limited, albeit well-established, validity in monitoring renal allograft patients for signs of tissue rejection. This technique provided an improved, semi-quantitative method for examining urine sediment and, in this patient, was helpful as a measure of renal disease activity.

Kaposi's sarcoma in a patient with SLE.

A 31-year-old woman with systemic lupus erythematosus (SLE) taking chronic corticosteroid therapy developed Kaposi's sarcoma. Three weeks after a single intravenous dose of cyclophosphamide for central nervous system vasculitis she died. Autopsy revealed disseminated Kaposi's sarcoma involving the skin and lung, as well as other visceral organs. This is the first case of widespread Kaposi's sarcoma developing in a patient with SLE.

Quinidine induced lupus syndrome.

Five patients with a lupus-like syndrome secondary to quinidine are described. Eleven other cases have previously been reported. The quinidine induced lupus syndrome is similar to that seen with procainamide and hydralazine treatment but occurs less frequently. The lower incidence may reflect a difference in the metabolism of quinidine. Quinidine should be considered as potentially responsible when multisystem disease appears in patients receiving this drug.

Congenital complete heart block with maternal primary Sjögren's syndrome.

We have described a case of congenital complete heart block associated with maternal primary Sjögren's syndrome. This diagnosis should also be considered when evaluating mothers of children with congenital heart block, especially when no connective tissue disease is otherwise clinically apparent. The potential significance of antibodies to SSA in this association remains to be determined.

Cryptococcal arthritis and cellulitis.

A middle-aged man with diabetes mellitus and cardiomyopathy developed both cryptococcal arthritis and cellulitis. Unusual aspects included the benign nature of the joint effusion and lack of contiguous osteomyelitis.

HLA-DR antigens in Blacks with rheumatoid arthritis and systemic lupus erythematosus.

HLA-DR locus antigens were studied in a large population of Black Americans with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). An association was found with DR4 in RA (p less than 0.001) and DR3 in SLE (p less than 0.01). Our findings are similar to those reported in Caucasians. No significant correlations between clinical manifestations and DR locus antigens were apparent in either disease. Our results support the association of D locus antigens with disease susceptibility more than with clinical severity.

Sulindac. A potentially renal-sparing nonsteroidal anti-inflammatory drug.

Three patients experienced rapidly reversible azotemia related to the use of naproxen or ibuprofen but tolerated full-dose sulindac. This article discusses renal toxicity of nonsteroidal anti-inflammatory drugs (NSAIDs), with emphasis on the role of inhibition of prostaglandin synthesis, and reviews evidence supporting a renal-sparing property of sulindac. The current literature assumes that all NSAIDs possess a similar potential for renal toxicity. The data presented suggest that sulindac has less potential for renal toxicity and may be the preferred NSAID for use in patients with impaired renal function.

Cardiac conduction abnormalities in Reiter's syndrome.

Reiter's syndrome was found in three men who presented with cardiac conduction disturbances. In two patients, Reiter's syndrome had been present for more than 30 years and had been previously unrecognized. These patients included a 67 year old man with complete heart block of 13 years' duration, and his son, who had left bundle branch block and chronic generalized cardiomyopathy. A chart review of 19 other patients with Reiter's syndrome who were seen at this institution disclosed five patients with conduction abnormalities. Transient first-degree heart block was the most common disturbance detected and was usually associated with active Reiter's syndrome. Some conduction abnormalities appeared after a long latent period at a time when other manifestations of Reiter's syndrome were inactive. An association with this disorder was therefore not obvious. In all five patients with Reiter's syndrome and conduction disturbances, testing for B27 antigen gave positive results. Both clinical and histopathologic changes in the heart in Reiter's syndrome are analogous to those in ankylosing spondylitis, also associated with B27 antigen. We suggest that the heart, like the joints and iris, may be a target organ for B27-associated disease by a mechanism that remains to be defined.

Tolmetin-induced aseptic meningitis.

A 21-year-old woman with systemic lupus erythematosus (SLE) had meningismus, conjunctivitis, lymphadenopathy, and elevation of liver function values following ibuprofen therapy. All symptoms and laboratory value abnormalities resolved rapidly when the drug therapy was stopped. Two years later, a similar reaction occurred after taking tolmetin sodium. Fever, adenopathy, aseptic meningitis with a polymorphonuclear pleocytosis, and serum transaminase level elevations resolved rapidly after use of the drug was discontinued. The mechanism of this reaction to nonsteroidal antiinflammatory drugs in patients with SLE is not known.

Photochemotherapy and psoriatic arthritis. A prospective study.

We have studied the temporal relation between psoriasis and psoriatic arthritis in 27 patients receiving photochemotherapy for treatment of psoriasis. Patients were classified as either spondylitic or nonspondylitic. For spondylitic patients, psoriasis was difficult to control, arthritis did not improve, and skin and joint activity appeared to vary independently. In contrast, 67% of nonspondylitic patients receiving photochemotherapy treatment remained clear of psoriasis, with 49% mean improvement in articular index. There was an inverse relation between initial percentage of psoriasis and improvement in peripheral arthritis. These results suggest that aggressive management of psoriasis helps control synovitis in at least a subgroup of patients with psoriatic arthritis.
