Medical Management of Rhino-Orbital Mucormycosis in a Diabetic Patient with Severe Chronic Kidney Disease: A Case Report
This case report describes the successful short-term management of rhino-orbital mucormycosis in a diabetic patient with severe chronic kidney disease using amphotericin B alone, demonstrating that favorable outcomes are possible without surgical debridement when early recognition and careful drug monitoring are employed.

In the human body, a delicate balance usually keeps microscopic invaders in check. When that balance is broken, particularly by uncontrolled diabetes or a weakened immune system, rare and aggressive fungi can seize the opportunity to take hold. One such group of fungi, known as Mucorales, causes an infection called mucormycosis. Unlike common molds that might grow on bread, these fungi are dangerous because they invade blood vessels, cutting off the blood supply to tissues and causing them to die and turn black. This process is especially perilous when the infection starts in the sinuses and spreads toward the eyes and brain, a condition known as rhino-orbital mucormycosis. The standard treatment for this life-threatening condition involves powerful antifungal medications, but these drugs often come with a severe side effect: they can damage the kidneys. This creates a difficult dilemma for doctors when treating patients who already have severe kidney failure, as the very medicine needed to save their lives could potentially destroy the organ that keeps them alive.
This story centers on a fifty-five-year-old man who arrived at Anwer Khan Modern Medical College Hospital in March 2022, carrying both of these critical problems. He had a long history of type 2 diabetes and high blood pressure, and for the past seven months, he had been suffering from severe chronic kidney disease. His condition had deteriorated rapidly over the preceding weeks. He complained of swelling around his right eye and face, a blocked nose, and a severe headache that would not go away. When doctors examined him, they saw the telltale signs of the fungal infection: black, dead tissue on his nose, lips, and around his eye, along with yellowish discharge. He was also confused and drowsy, suggesting the infection might have spread into his brain. His blood tests revealed a body in crisis, with extremely high blood sugar levels and kidney function that had dropped to a critical point, with a creatinine level of 7.6 milligrams per deciliter, far above the normal range.
The medical team faced an immediate challenge. The patient needed urgent treatment to stop the fungus, but the most effective drug, a medication called amphotericin B, is known to be toxic to the kidneys. In a patient whose kidneys were already failing, using this drug carried a high risk of causing total organ failure. Furthermore, the standard protocol for this type of infection usually involves surgery to cut away the dead, infected tissue. However, given the patient's fragile state and the extent of the infection, the doctors decided to hold off on surgery for the moment. Instead, they chose to rely entirely on medical management. They began administering the antifungal drug intravenously at a dose of eighty milligrams daily, while simultaneously working to control his blood sugar with insulin and providing supportive care to keep his body stable.
Over the course of his hospital stay, the patient's condition began to turn around. The black, dead tissue on his face started to recede, and his mental state cleared up. He did not suffer any further decline in his kidney function, nor did he experience the severe side effects that often accompany this treatment in patients with pre-existing kidney disease. He was eventually discharged in an improving condition, with the infection under control and no need for the surgical removal of tissue that is typically required. This outcome was notable because it demonstrated that, in this specific case, aggressive medical therapy alone was sufficient to stabilize a patient with a severe, potentially fatal infection and advanced kidney disease.
The doctors who treated him emphasized that this result was a fortunate exception rather than a new rule. While the patient improved without surgery, the medical community still considers surgical removal of infected tissue to be a vital part of the standard treatment plan whenever it is possible. The success in this case relied on the patient's ability to tolerate the medication and the careful, constant monitoring of his body's response. The report highlights the importance of recognizing the early signs of this infection, such as facial swelling and black tissue, especially in people with diabetes. It also underscores the delicate balance doctors must strike when treating complex patients, where the cure must be managed just as carefully as the disease itself. While this single story offers hope and a glimpse into how such a difficult situation can be navigated, it remains a unique observation that requires further study to understand how it might apply to others.
