Lower limb giant cell arteritis and temporal arteritis: followup of 8 cases.

Among 8 patients with giant cell arteritis (GCA) (6 women, 2 men) whose clinical presentations were compatible with temporal arteritis (TA), 6 were followed for 37-105 (mean 74.9) months, one died shortly after treatment onset, and the last was asymptomatic (10 mg steroids/day) when lost to followup at 29 months. All 8 patients had bilateral leg claudication of recent onset; for 6 patients, this was the first symptom. All leg angiograms showed multiple, bilateral, long and smooth stenoses, thromboses, or both. Biopsies of diseased leg arteries from 4 patients provided histological proof of GCA; another case was histologically proven post mortem. Among the 5 patients who met at least 3 American College of Rheumatology criteria of GCA or TA, 3 without histologically documented leg GCA also had biopsy proven temporal GCA (n = 1), or headaches and claudication and angiographic inflammatory arteritis of the arms (n = 2). All patients received steroids; 3 had bypasses, one with endarterectomy. Five are asymptomatic after 24-100 months of steroids (mean 50.6). Revascularization was not successful; one amputation was necessary. Large artery involvement in GCA can affect the legs. Bilateral and rapidly progressive intermittent claudication of recent onset is the most common symptom, even in the absence of headaches or the presence of a silent inflammatory syndrome. Early diagnosis allows rapid initiation of steroid therapy, which is usually able to generate a sufficiently good response to avoid vascular surgery.

Polymyositis and dermatomyositis: short term and longterm outcome, and predictive factors of prognosis.

OBJECTIVE: To assess short term and longterm outcome of polymyositis (PM) and dermatomyositis (DM), and predictive variables of PM/DM course. METHODS: The medical records of 77 consecutive patients with PM/DM were reviewed. The criteria for PM/DM diagnosis were based upon Bohan and Peter criteria. RESULTS: Thirty-one patients (40%) achieved remission of PM/DM, whereas 33 (43%) improved and 13 (17%) worsened their clinical status. Short term recurrences of PM/DM (during tapering of therapy) occurred in 36 patients and longterm recurrences (after discontinuation of therapy) in 9 patients. PM/DM were associated with both decreased functional status and quality of life at longterm followup: (1) only 52% of patients considered to be in remission experienced a return to previous normal activities; and (2) 45% of the other patients with nonremitting PM/DM still had a marked reduction of activities (as shown by the disability scale of the Health Assessment Questionnaire). Overall mortality was as high as 22%, and the main causes of death were cancer and lung complications. Factors associated with PM/DM remission were younger age and shorter duration of clinical manifestations prior to therapy initiation. Variables associated with poor outcome of PM/DM were older age, pulmonary and esophageal involvement, and cancer. CONCLUSION: Our series shows both high morbidity and mortality related to PM/DM, emphasizing that management of PM/DM patients at an early stage is required. Lung complications (i.e., aspiration pneumonia due to PM/DM related esophageal dysfunction and ventilatory insufficiency) were one of the main causes of death in our series, indicating that investigating for subclinical esophageal and lung impairment should become an integral part of initial PM/DM evaluation. The presence of poor prognostic factors should prompt both close followup and aggressive therapy in patients with PM/DM.

Susac's syndrome or retinocochleocerebral vasculopathy: a misdiagnosed and overlooked disorder.

We report a case of Susac's syndrome (retinocochleocerebral vasculopathy) that was initially successfully treated with steroids. The patient had a recurrence of the disorder 2 years after the onset of the first clinical manifestations; this was treated with steroids and both calcium channel blockers and aspirin. Our findings underline the importance of recognizing patients with retinocochleocerebral vasculopathy at an early stage so that it may be accurately managed and, therefore, result in both decreased morbidity and disability related to severe sequelae. We also stress the need for patients with Susac's syndrome to have both close and long-term follow-up in order to disclose both symptomatic and asymptomatic recurrences of the disorder.

Hypertrophic osteoarthropathy can indicate recurrence of Whipple's disease.

We report the case of a patient with Whipple's disease (WD) who developed hypertrophic osteoarthropathy (HOA) characterized by digital clubbing, periostosis of the tubular bones, and polysynovitis. The HOA disclosed the recurrence of the patient's WD, since polymerase chain reaction (PCR) analysis clearly demonstrated the presence of Tropheryma whippelii in the synovial fluid from the patient's left knee. Initiation of appropriate antibiotic therapy resulted in complete healing of all clinical rheumatologic manifestations within 2 months and in disappearance of radiographic bone changes at 7-month followup. We suggest that HOA be included within the spectrum of rheumatologic manifestations of WD, and that an evaluation for WD should be considered in patients, especially middle-aged men, presenting with HOA even without gastrointestinal symptoms. PCR analysis may be useful in accurate diagnosis and management of early WD with unusual clinical manifestations, and may contribute to decreased morbidity and mortality.

[Pulmonary involvement in systemic scleroderma. Part I. Chronic fibrosing interstitial lung disease].

INTRODUCTION: Chronic pulmonary interstitial fibrosis is the most frequent respiratory manifestation in systemic sclerosis, occurring in 80% of cases. It remains a severe complication of the disease and is the primary cause of mortality related to respiratory insufficiency in 20 to 60% of cases. CURRENT KNOWLEDGE AND KEY POINTS: The date of onset of interstitial lung disease remains undetermined, and only in rare cases does it reveal the presence of systemic sclerosis. The clinical signs are only observable at a later stage, when at least 50% of the lung parenchyma is affected. The methods of choice adopted for early diagnosis of this disease are high resolution computed tomography and pulmonary functional investigations; they should be carried out during the preliminary investigation and at follow-up once a year. Moreover, high resolution computed tomography also provides prognostic data, for there is a correlation between the type of lesion and its severity as determined by high resolution computed tomography and by histological findings. The value of other methods of investigation, in particular bronchoalveolar lavage, has not yet been clearly established. The association of cyclophosphamide and corticoids is currently being evaluated (indications, administration modalities, duration), and this combination may be the most effective treatment. FUTURE PROSPECTS AND PROJECTS: Interstitial lung disease is one of the major causes of morbidity and mortality in systemic sclerosis. Early diagnosis and management of this disease is therefore of utmost importance.

[Pulmonary involvement in systemic scleroderma. Part II. Isolated pulmonary arterial hypertension, bronchopulmonary cancer, alveolar hemorrhage].

INTRODUCTION: Pulmonary interstitial fibrosis is the most frequent cause of lung disease in systemic sclerosis. However, other pulmonary complications exist, including lung cancer, alveolar hemorrhage, and in particular isolated pulmonary arterial hypertension, which is still considered the bête noire as regards this disease. CURRENT KNOWLEDGE AND KEY POINTS: The prevalence of pulmonary arterial hypertension has been reported to range from 5 to 60% in cases of systemic sclerosis; isolated pulmonary arterial hypertension has been principally observed in subjects with a ten-year history of limited forms of the disease. As the patient remains asymptomatic for a long period, with nonspecific respiratory clinical manifestations, the diagnosis is made at a much later stage in the course of the disease. The diagnostic method of choice is echocardiography-doppler, which should be performed during the preliminary investigation, and at follow-up. The prognosis is poor, and patient survival rate at 2 years after onset of symptoms amounts to 40%. To date, no curative therapy for pulmonary arterial hypertension has yet been found. FUTURE PROSPECTS AND PROJECTS: A knowledge of the mechanisms involved in the development of isolated pulmonary arterial hypertension is essential to the determination of new and relevant therapeutic strategies. Vasodilatory treatment, notably calcium channel blockers, prostacyclin and analogs such as iloprost, may be effective at an early stage of the disease before the appearance of permanent vascular damage.
