Pyoderma gangrenosum complicating Crohn's disease.

Of the many acknowledged systemic complications of inflammatory bowel disease, arthritis, iritis and erythema nodosum are observed most commonly and considered parts of the natural history. Pyoderma gangrenosum is a more ominous, less common but similarly associated complication that classically occurs in the course of ulcerative colitis. Its rarity in Crohn's disease stimulated the following report.

Mucosal-cell counts in ulcerative and granulomatous colitis.

Epithelial and connective-tissue cells were counted in rectal mucosal biopsies from 215 patients with ulcerative colitis, 98 patients with granulomatous colitis, and 50 controls. The results were analyzed statistically. Significantly decreased mucous goblet cells were found both in sigmoidoscopically abnormal ulcerative colitis and in granulomatous colitis, and they increased during the healing process. More pyknotic and karyorrhectic epithelial cells occurred in active ulcerative colitis than in granulomatous colitis. Inactive ulcerative colitis still manifested histologic evidence of acute and chronic inflammation, while sigmoidoscopically normal granulomatous colitis biopsies after previous gross rectal disease showed significantly increased macrophages in the lamina propria. Cell counts were valuable for differential diagnosis after the sigmoidoscopic appearance became normal. The acute inflammation of ulcerative colitis, as indicated by neutrophils, was decreased most notably following therapy with prednisone or 6-mercaptopurine. Chronic inflammation associated with fewer plasma cells was decreased after salicylazosulfapyridine as well as either of the other two drugs; macrophages, indicators of healing, increased most after 6-mercaptopurine combined with another anti-inflammatory agent.

Responses to drug therapy in ulcerative colitis. Evaluation by rectal biopsy and histopathological changes.

To evaluate responses to medical therapy in ulcerative colitis, rectal biopsies of patients with active untreated disease, individuals with positive and negative sigmoidoscopic findings treated with salicylazosulfapyridine, prednisone and 6-mercaptopurine, alone and in combinations and noncolitis controls were compared histologically. Predominant histological observations were analyzed statistically. There were fewer crypt abscesses but more mucosal edema after all forms of therapy. Quantitative histopathological analysis failed to demonstrate that the response to one drug was significantly different from another.

Growth retardation in children with ulcerative colitis: the effect of medical and surgical therapy.

The growth of 37 children with ulcerative colitis have been analyzed. While conventional growth charts showed only percentile changes in height, height data plotted on Tanner et al.'s growth charts showed increases and decreases in growth velocity. Growth retardation is a prominent complication of ulcerative colitis with onset on bowel symptoms. Both ulcerative colitis and "high-dose" steroid therapy (greater than 12 mg/sq m/day of cortisol) can hinder growth but in some instances there is a growth spurt after high-dose steroid therapy. "Low-dose" steroid therapy does not retard growth. Colectomy is more effective than high-dose steroid therapy in reversing the growth retardation caused by ulcerative colitis and is of greatest value if not delayed too long. Growth following subtotal colectomy with ileorectal anastomosis (Aylett procedure) is not likely to be as much as that after subtotal colectomy with ileostomy. Growth retardation is infrequently the only indication for surgical intervention but ileostomy and colectomy are appropriate for this complication of ulcertive colitis in itself when not improved by adequate medical treatment.
