Aldoosiin

Aldoosiin is a rare genetic disorder characterized by a deficiency in the enzyme aldose reductase, which plays a crucial role in the metabolism of glucose and other sugars. This enzyme is part of the polyol pathway, a metabolic route that converts glucose into sorbitol and fructose, primarily in tissues such as the lens of the eye, retina, nerve fibers, and kidney. In individuals with aldosiin, the enzyme is either absent or significantly reduced, leading to an accumulation of sorbitol and fructose within these tissues.

The primary symptoms of aldosiin often manifest in the eyes, causing conditions such as cataracts, which can develop at an early age. Retinal damage may also occur, potentially leading to vision loss or blindness. Other affected areas include the nerves, where the condition can result in peripheral neuropathy, characterized by numbness, pain, or weakness in the extremities. Kidney problems, such as nephropathy, may also develop due to the buildup of polyols in the renal tissues.

Diagnosis of aldosiin typically involves genetic testing to confirm the presence of the enzyme deficiency. Blood or urine tests may also be conducted to detect elevated levels of sorbitol or fructose. Early diagnosis is essential for managing symptoms and preventing complications.

Treatment options are limited but may include medications like aldose reductase inhibitors, which aim to reduce the accumulation of polyols. Lifestyle adjustments, such as monitoring blood sugar levels and maintaining a balanced diet, can help manage symptoms. Supportive care, including physical therapy for neuropathy and regular eye examinations, is also important for individuals with aldosiin. Research into potential gene therapies and further advancements in treatment are ongoing to improve outcomes for affected individuals.
