Abstract:
Alkaptonuric ochronosis is a rare cause of aortic valve stenosis. We report the case of a 61-year-old female patient with alkaptonuria who presented to our institute with the clinical picture of severe aortic valve stenosis, which was confirmed by transthoracic echocardiography. On aortotomy, she was noted to have an impressive black discoloration of ascending aorta and the aortic root complex involving the aortic valve leaflets. She underwent an uneventful aortic valve replacement. She was discharged home 10 days postoperatively.

Abstract:
Alkaptonuria is a rare metabolic autosomal recessive disorder. It occurs due to lack of an enzyme that results in deposition of homogentisic acid in various tissues. A male patient of 45 years presented with back pain for 20 years and multiple joint pain for 10 years. Patient has multiple nodules in both pinnae and pigmentation in both sclerae. His urine turns black upon standing. These findings are compatible with the diagnosis of Alkaptonuria.Bang Med J (Khulna) 2016; 49 : 37-39

Alkaptonuria (AKU) is an ultra-rare genetic disease resulting from a deficient activity of the enzyme homogentisate 1,2- dioxygenase (HGD), responsible for the catabolism of the aromatic amino acids Phenylalanine and Tyrosine. This condition leads to the accumulation of a toxic metabolite, HGA and of its product of oxidation BQA, whose polymerization generates melanin-like aggregates, with amyloidogenic properties, leading to the phenomenon of “Ochronosis”. The most affected structures by the deposition of these ochronotic aggregates are joints, which undergo severe arthropathy; therefore, art

Abstract:
Alkaptonuria (AKU) is an ultra-rare, autosomal recessive disorder of tyrosine catabolism due to mutations within the homogentisate 1,2-dioxygenase (HGD) gene. The resulting enzyme deficiency leads to accumulation of homogentisic acid (HGA) and deposition of melanin-like pigment polymers in the connective tissues of the body in a process called ochronosis. This leads to debilitating early onset osteoarthropathy, renal damage and aortic valve disease. As a multisystem disorder, AKU results in progressive and chronic pain and severe morbidity. Most management approaches for AKU are palliative and

Alkaptonuria (AKU) arises from a genetic deficiency of homogentisate 1,2 dioxygenase (HGD) an enzyme involved in tyrosine metabolism. AKU is characterised by high circulating homogentisic acid (HGA) some of which is deposited as ochronotic pigment in connective tissues, mainly cartilage, leading to multisystemic damage dominated by premature severe osteoarthropathy. Pathological changes in the spine as a result of ochronosis can be imaged using fluorine-18 labelled sodium fluoride positron emission tomography (18F-NaF PET).

Alkaptonuria (AKU) is an ultra rare autosomal recessive disorder resulting from a deficiency of the homogentisate 1,2-dioxygenase (Hgd) enzyme and is characterized by accumulation of homogentisic acid (HGA) in plasma. The disorder has three distinct stages of disease beginning with the excretion of large quantities of HGA in the urine, followed by deposition of HGA as a polymerized pigment in collagenous tissues principally in the cartilages of loaded joints (termed ochronosis), and finally the early onset of severe and devastating osteoarthropathy.

Abstract:
Alkaptonuria (AKU) is an autosomal recessive disorder, called also Black Bone Disease, for the characteristic dark coloration that some tissues and parts of the body assumed. The pathology is caused by the failure of the enzyme homogentisate 1,2- dioxygenase (HGD), that leads the accumulation of the metabolic intermediate homogentisic acid (HGA), derived by tyrosine. HGA highly reactivity triggers the formation of HGA-derived oxidized products, that react with cellular macromolecules, causing a significant generation of ROS and occurrence of oxidative stress.

Abstract:
Alkaptonuria is an autosomal recessive disorder with an incidence of 1:250,000 to 1:500,000. Aside from urine that darkens, the disease is relatively asymptomatic in childhood. As a result, the diagnosis is often overlooked early in life and not considered in many patients until they begin to manifest symptoms as adults. Features include pigment deposition (ochronosis) on the eyes, ears, and hands; early-onset, progressive arthritis, particularly of the spine and large joints; valvular heart disease; and renal and prostate stones. Management continues to be symptomatic, but specific treatment
