Diabetes and rhino-orbito-cerebral mucormycosis – A deadly duo

Rhino-orbito-cerebral mucormycosis(ROCM) is an uncommon yet potentially fatal fungal infection predominantly seen in immunocompromised individuals. However, there is very limited data available from India regarding outcome of patients with ROCM and diabetes mellitus.

To ascertain clinical parameters and factors in the final outcome of patients with diabetes mellitus and ROCM.

This series included retrospective analysis of medical records of 91 patients with diabetes mellitus who were diagnosed with ROCM from january 2007 to june 2019 at a tertiary care hospital in Punjab.

The mean age of patients was 52.6 years (range 18–82 years), with men constituting the majority (71.4 %). Ophthalmoplegia was the most frequent presenting feature seen in 77 % of patients followed by proptosis (71 %). Intracranial involvement was seen in 20 % of the patients and cavernous sinus thrombosis was diagnosed in 9(10 %) patients. Out of 91 patients, 81 patients were subjected to appropriate surgical procedure depending upon site and extent of involvement by mucorales. A total of 53 (58.2 %) patients survived while 38(41.8 %) patients succumbed. Delay in presentation to hospital, intracranial extension and loss of vision at presentation adversely affected the outcome (p < 0.05). Aggressive surgical management in the form of multiple debridements was superior to single debridement (p < 0.05). Diabetic ketoacidosis did not significantly affect the outcome (p = 0.359).

ROCM in patients with diabetes mellitus, is a rapidly progressive disease with a high fatality rate and grave outcome unless diagnosed early and managed aggressively.
