Abstract

Background and Objective: Renal failure, pulmonary hypertension, and interstitial lung disease are major causes of morbidity and mortality in systemic sclerosis (SSc). However, the concomitant occurrence of pulmonary hemorrhage associated with acute renal failure in SSc has been rarely described. The present study is the first analysis of pulmonary-renal syndrome in SSc. Patient and Methods: We present a 44-year-old woman with SSc who died of a fulminant course of acute renal failure associated with diffuse alveolar hemorrhage. We termed this uncommon and fatal complication of SSc scleroderma-pulmonary-renal syndrome (SPRS). A search of the English-written literature yielded reports of 10 additional similar cases. These patients, together with our present case, form the basis of the present analysis. Results: The average age of the patients with SPRS was 46 years. The majority of the patients (80%) were women, and most had diffuse SSc. SPRS occurred an average of 6.4 years after disease onset and was associated with prior fibrosing alveolitis and/or D-penicillamine treatment. Interestingly, normotensive renal failure seems to characterize the scleroderma patients, because 9 of 11 (82%) had normal blood pressure. SPRS bears a poor prognosis: all of the 11 patients (100%) died within 12 months of admission. However, only 60% of the 5 patients for whom we have treatment data received corticosteroids. Conclusions: Pulmonary-renal syndrome is a rare but fatal complication of SSc. Because the treatment data are scarce and the prognosis is poor, aggressive treatment with pulse corticosteroids, cyclophosphamide, and possibly plasmapheresis is suggested.

Methods

In addition to the case reported here, we performed a MEDLINE search of all English-written reports, articles, and reviews that had been published during the period of 1966 to 2000, using “pulmonary hemorrhage” or “alveolar hemorrhage” and “scleroderma” or “systemic sclerosis” as search words. All relevant articles were carefully reviewed, and the data were summarized. SSc was defined according to the classification criteria of the American Rheumatism Association (10). We looked for concomitant

Case report

A 44-year-old woman with limited cutaneous SSc of 8 years' duration was admitted with fever and dyspnea. During the last years she had been functionally quite stable, despite mild reduction of lung volumes on spirometry. During that period she had been treated with D-penicillamine. Her blood pressure and renal and hepatic functions had been normal. Two months before the last admission she was hospitalized because of pulmonary edema and hypertension of 220/110 mm Hg. The serum creatinine level

Literature review

The literature search revealed 10 additional cases of pulmonary hemorrhage with concomitant acute renal failure that fulfilled our definition of SPRS 12, 13, 14, 15. The reports of these patients, together with our present case, form the basis of the present analysis (Table 1).The data for the 6 cases with normotensive renal failure associated with pulmonary hemorrhage reported by Helfrich et al are limited (12).

Discussion

Our patient, who had a 7-year history of slowly progressive but functionally stable limited cutaneous SSc, succumbed to SPRS, which was manifested by acute respiratory insufficiency with pulmonary hemorrhage, together with rapidly progressive renal failure caused by scleroderma kidney disease.

This ominous combination of rapidly progressive renal failure and alveolar hemorrhage has been designated pulmonary-renal syndrome and has been previously reported in systemic lupus erythematosus, mixed

      Normotensive renal crisis requires the presence of other features, primarily rapidly progressive unexplained azotemia and/or microangiopathic hemolytic anemia with thrombocytopenia. Pulmonary hemorrhagic is a rare life-threatening problem, which has occurred in several of these patients [20,55]. It complicates the diagnosis and is a poor prognostic sign.

      The association of SSc with pulmonary haemorrhage is well-recognized. Pulmonary renal syndrome is a rare complication of SSc, consisting of diffuse pulmonary haemorrhage associated with acute renal failure and has a poor prognosis.24 Several drugs used in the management of SSc are capable of causing infiltrative lung disease, but there are no data on the incidence of drug-related disease in SSc.
