PURPOSE: To ascertain the therapeutic effect of periocular corticosteroids in diabetic papillopathy. METHODS: Prospectively, five consecutive adult-onset diabetic patients with symptomatic diabetic papillopathy underwent visual fields and fluorescein angiography before and after superonasal subtenon injection of corticosteroids. RESULTS: The median duration of papillopathy was 2.5 weeks by ophthalmoscopy and 3 weeks by fluorescein angiography. The median recovery time of best-spectacle-corrected visual acuity was 2 weeks. Two patients developed sequential diabetic papillopathy, and both reported faster visual recovery and better subjective vision in treated eyes. In these two patients, the final best-spectacle-corrected visual acuity and visual evoked responses were comparable between the two eyes, while automated visual fields were less constricted in treated eyes. Complications included ocular hypertension, mild progression of cataract, and mild ptosis in one patient each. CONCLUSIONS: Periocular corticosteroids shortened the duration of diabetic papillopathy from a reported median of 5 months to 3 weeks in the present uncontrolled observational study, partly by their angiostatic and antioedema effects at the level of the anterior optic nerve. Intraocular pressure needs to be monitored in eyes receiving periocular corticosteroids.
BACKGROUND: Adults with chronic idiopathic thrombocytopenic purpura (ITP) in whom standard-dose corticosteroids and splenectomy have failed or who have contraindications to these therapies often require further treatment for life-threatening thrombocytopenia or bleeding. We studied whether danazol, an attenuated androgen, is useful in this setting. METHODS: To assess both clinical outcome and tolerance issues, 57 patients who had refractory chronic ITP (n = 27) or who had contraindications to splenectomy or corticosteroids or who refused these therapeutic options (n = 30) were studied. RESULTS: Thirty-eight patients experienced a partial or complete response to therapy (67%), among whom 27 (46%) remained in remission at a median (+/- SD) of 119 +/- 45 months. Treatment tolerance was acceptable, although severe adverse events were reported in 9 patients (16%). CONCLUSION: Our findings suggest that danazol therapy may be beneficial in the management of refractory chronic ITP or when there are contraindications to splenectomy or corticosteroids (or both).
Studies using dual-energy X-ray absorptiometry have suggested a high prevalence of osteoporosis in inflammatory bowel disease. However, population-based data on fracture incidence suggest only a small increased risk of fracture amongst patients with inflammatory bowel disease compared with the general population. Therefore, it would be helpful to identify patients with inflammatory bowel disease at particularly high risk for fracture so that these risks might be modified or interventions might be undertaken. The data on calcium intake as a predictor of bone mineral density are conflicting. Although there are data suggesting that a one-time survey to determine current calcium intake will not help to predict bone mineral density in inflammatory bowel disease, persistently reduced calcium intake does appear to lead to lower bone mineral density. In the general population, body mass is strongly correlated with bone mineral density, which also appears to be true in Crohn's disease. Hence, subjects with inflammatory bowel disease and considerable weight loss, or who are obviously malnourished, could be considered for bone mineral density testing, and the finding of a low bone mineral density would suggest the need for more aggressive nutritional support. Although vitamin D is undoubtedly important in bone health, vitamin D intake and serum vitamin D levels do not correlate well with bone mineral density. Sex hormone deficiency can also adversely affect bone health, although a well-developed strategy for sex hormone measurements in patients with inflammatory bowel disease remains to be established. Ultimately, the determination of genetic mutations that accurately predict fracture susceptibility may be the best hope for developing a simplified strategy for managing bone health in inflammatory bowel disease. The therapy of osteoporosis in inflammatory bowel disease has been adapted from other osteoporosis settings, such as post-menopausal or corticosteroid-induced osteoporosis. To date, there remains no therapy proven to be efficacious in inflammatory bowel disease-related osteoporosis; however, calcium and vitamin D supplementation and bisphosphonates have their roles.
