[Correlations of histologic classification with clinical features and prognosis in interstitial lung disease associated with collagen disease].

We studied 32 patients with interstitial pneumonia associated with collagen disease. All underwent surgical lung biopsy. Twenty-seven were histologically classified as follows: 8 with usual interstitial pneumonia (UIP), 10 with nonspecific interstitial pneumonia (NSIP), 6 with bronchiolitis obliterans organizing pneumonia (BOOP), and 3 with diffuse alveolar damage (DAD). Twenty-five of the patients were treated with corticosteroid but 4 (3 DAD, 1 NSIP) deteriorated rapidly and died within a month after lung biopsy. At the final follow-up, all 8 UIP patients were alive with residual respiratory impairment, whereas 6 NSIP and 4 BOOP patients had almost completely recovered. These findings suggested that histologic classification can be highly valuable to the therapeutic responsiveness and prognosis in cases of interstitial pneumonia associated with collagen disease.

Radiological aspects of collagen diseases.

The collagen diseases, an ill-defined group of clinical entities, have as their basis a generalized alteration of the connective tissue, especially of its extracellular components. They include periarteritis nodosa, disseminated lupus erythematosus, dermatomyositis, scleroderma, rheumatic fever and rheumatoid arthritis. The radiological findings in a series of cases of these diseases were reviewed. In 28 cases of periarteritis, 20 cases showed some abnormal findings in the thorax. These included pleural effusions, pulmonary changes, pericardial effusions and cardiac enlargement. In 32 cases of disseminated lupus erythematosus, thoracic findings were noted in 21. They resembled the changes found in periarteritis. In some 25 cases of scleroderma, diverse radiological findings were noted. These included "cystic" changes in the lungs (one case) and pulmonary "hives." In the intestinal tract esophageal and small bowel alterations were found, both ectatic and stenotic. In the soft tissues of the "pressure areas" variable degrees of calcification were observed. Dermatomyositis is the rarest of the collagen disease group; only one autopsy-proven case is available for study. Chest x-rays taken a year before death showed slight cardiac enlargement. The lungs were clear. In acute rheumatic fever, x-ray examination may disclose pericardial or pleural effusion, and so-called rheumatic pneumonitis; the latter has no specific diagnostic features. Soft tissue swellings may develop around some of the joints. In rheumatoid arthritis, joint changes are numerous and fairly characteristic, and are followed in many cases by fibrous or bony ankylosis and deformities of considerable degree. Awareness of the commoner radiological changes in this entire group of diseases should result in earlier establishment of diagnosis, especially in the more obscure examples.

The collagen diseases.

The collagen diseases have in common certain relatively specific alterations in the tissues that are derived from the mesenchyme.In reviewing the development of this concept, the nature and the pathogenesis of these changes and the blocking effect of cortisone and ACTH are discussed. The term "diseases of the collagen system" includes a number of clinical states within a broad spectrum of variation in the basic alterations of collagenous and vascular tissues. In rheumatoid arthritis the modifications are chiefly in the somatic connective tissue; in periarteritis nodosa the blood vessel involvement is preeminent; dermatomyositis and disseminated lupus erythematosus present more intermediate mixtures of these changes.

Risk factors of abdominal surgery in patients with collagen diseases.

Patients with collagen diseases have been reported to demonstrate a greater risk when undergoing surgical operations. To determine the risk factors in abdominal surgery for patients with collagen diseases, 32 patients with collagen diseases who underwent abdominal surgery were analyzed for their clinical features and surgical results by comparing 26 cases from the favorable prognosis group (Group A) and 6 cases resulting in hospital death (Group B). The analysis revealed that emergent operations tended to result in worse outcomes (P = 0.011) than elective operations and that cases undergoing operations for collagen disease-related problems, including intestinal perforation and acute pancreatitis, also showed a worse postoperative course than those who underwent operations for problems unrelated to collagen diseases, such as carcinomas and cholelithiasis (P = 0.0006). The dose of steroids administered at the time of operation was also significantly higher in Group B than in Group A (P = 0.03). These results suggested that the patients with collagen diseases should be followed periodically not only for the primary disease but also for any potential surgical diseases to identify such diseases at an early stage and to avoid an emergent operation, and that patients treated with high doses of steroids also need intensive care after abdominal surgery.
