Abstract (sommario):

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

Abstract (sommario):

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 (sommario):

✓ Alkaptonuria is a rare metabolic disease caused by deficiency of homogentisic acid oxidase and characterized by bluish-black discoloration of cartilages and skin (ochronosis). The authors report the cases of three patients with lumbar disc herniation who underwent discectomy and in whom the nucleus pulposus was discovered to be black. Alkaptonuria was diagnosed after discectomy. Discal herniation requiring surgery is unusual in alkaptonuria, with only a few reports. The symptoms in the three patients disappeared after surgery and no symptoms were demonstrated on follow-up examination.

Abstract (sommario):

AbstractBackground:Alkaptonuria is an inborn error of metabolism. It is a multisystem disease with characteristic ENT manifestations. This paper reports, for the first time, the ENT findings in a cohort of alkaptonuria patients.Method:Patients attending the National Centre for Alkaptonuria (Royal Liverpool and Broadgreen University Hospitals NHS Trust) underwent a full ENT assessment.Results:Eighteen of the 20 patients (90 per cent) had an ENT sign or symptom. These included discolouration of the pinna, cerumen, nasal septum and pharynx.Conclusion:Discolouration of cerumen may occur before 30 years of age and may therefore be an important early clinical sign. Further audiological assessment of patients is needed to clarify if an association exists between alkaptonuria and hearing loss. Alkaptonuria is a condition that could present to the otolaryngologist. Successful early diagnosis and referral to a specialist centre is essential so that patients can be offered disease-modifying therapy.

Abstract (sommario):

Alkaptonuria is rare autosomal recessive multisystem disease, caused by mutations in the homogentisine oxidase gene, which leads to the deposition of metabolites of homogentisic acid in organs and tissues (ochronosis).The purpose: to study spectrum of ophthalmic manifestations of alkaptonuria in Russian cohort of patients of different ages.Material and methods. Ophthalmological examination of 9 patients: 5 adults aged from 39 to 64 years and 4 children aged from 3 to 6 years with confirmed diagnosis of “alkaptonuria” was performed.Results. In all adult patients bilateral brown-black scleral pigmentation and yellow-brown deposits in the conjunctiva in the region of the palpebral fissure were detected paralymbally, the severity of which correlated with age, tortuosity and vasodilation of the conjunctiva in areas of deposits. In 1 out of 4 children minimal deposits of yellow pigment were found in the conjunctiva of the limb. In patients older than 60 years typical small brownish deposits were observed in the cornea near the limb in the region of the palpebral fissure.Conclusion. Eye changes are one of the most common clinical manifestations of alkaptonuria. Typical manifestations are the sclera’s pigmentation, conjunctiva and cornea in the limb. Ophthalmological examination is non-invasive informative method that can help in early diagnosis, differential diagnostics, assessment of the dynamics of the disease and the effectiveness of the therapy.

Abstract (sommario):

When urine samples from alkaptonuria patients are allowed to stand, they turn black, presumably owing to the oxidation of homogentisic acid to a melanin-like substance. We report the characterization of the pigments formed by polymerization of (a) the components in the urine from a patient with alkaptonuria and (b) homogentisic acid. The absorption spectra and electron spin resonance signals of these pigments are similar to those of eumelanins. Irradiation of the pigments with nitroblue tetrazolium caused reduction of the tetrazolium; this was partially inhibited by superoxide dismutase. Irradiation of Ehrlich ascites carcinoma cells with the pigments from homogentisic acid or urine caused cell lysis. Since this lysis was inhibited by catalase, we have concluded that it was mediated by H2O2. A similar pigment was also extracted from the tissue from an alkaptonuria patient. It is suggested that the degeneration of tissue in vivo may be due to the deposition of melanin-like pigments in the tissues, probably in combination with metal ions.Key words: alkaptonuria, homogentisic acid, pigmentation, melanin, photosensitization.

Abstract (sommario):

Alkaptonuria is a rare autosomal-recessive metabolic disorder of tyrosine degradation which results in elevated levels of circulating homogentisic acid. Ochronosis occurs when homogentisic acid polymerizes and deposits in connective tissue. Ochronotic lesions in the carotid arteries have not been described. In this report, we describe a 65-year-old man with alkaptonuria, with hypertension and hyperlipidemia, who underwent an uneventful carotid endarterectomy for an asymptomatic high-grade internal carotid artery stenosis. Histology revealed homogentisic acid deposits as black-brownish areas in the intima. He was noted to have an impressive heavily brown-black pigmented discoloration of the carotid plaque. Cardiovascular involvement is a rare consequence of alkaptonuria and is manifested by pigment deposition at the areas influenced by shear stress and turbulence.

Abstract (sommario):

AbstractObjective:To report an extremely rare case of dark pigmentation on the tympanic membrane due to alkaptonuria, and to discuss the probable association between this condition and hearing loss.Case report:A 58-year-old man with alkaptonuria was admitted with tinnitus and hearing loss in both ears. Physical examination showed bluish-black pigmentation on the helixes of both ears and both sclerae. Otoscopic examination revealed dark discolouration of both tympanic membranes. Audiological evaluation revealed mixed high frequency hearing loss in both ears. Tympanometric examination revealed type A tympanograms bilaterally, and absence of acoustic reflexes both ipsilaterally and contralaterally. Computed tomography of the temporal bones revealed no abnormality.Conclusion:Clinicians should consider alkaptonuria in the differential diagnosis of patients with abnormal tympanic membrane pigmentation and hearing loss.

Abstract (sommario):

Background. Metabolic disorder alkaptonuria is an autosomal recessive disorder caused by mutations in the HGD gene, and a deficiency HGD enzyme activity results in an accumulation of homogentisic acid (HGA), ochronosis, and destruction of connective tissue. Methods. We clinically evaluated 18 alkaptonuria patients (age range, 3 to 60 years) from four unrelated families. Furthermore, 11 out of 18 alkaptonuria patients and 7 unaffected members were enrolled for molecular investigations by utilizing Sanger sequencing to identify variants of the 14 exons of HGD gene. Results. We found that the seven patients from the 4 unrelated families carried a recurrent pathogenic missense variant (c.365C>T, p. Ala122Val) in exon 6 of HGD gene. The variant was fully segregated with the disease in affected family members while the other unaffected family members were heterozygous carriers for this variant. Additionally, the clinical features were fully predicted with alkaptonuria disorder. Conclusion. In this study, we confirmed that the most common variants in Jordanian AKU patients was c.365C>T, p. Ala122Val in exon 6 of HGD gene. Additionally, we correlated the clinical and genetic features of AKU patients at various ages (3-60 years).

Abstract (sommario):

Insignificant population frequency of alkaptonuria - 3-5 per 1,000,000 (H.P. Bochkov et al., 1984), autosomal recessive character of inheritance, which often does not give family accumulation, late development of clinical symptoms (after 40 years) lead to that practical doctors, rarely meeting with the specified pathology and having no indication of family or congenital character of the disease, find it difficult to make a diagnosis.

Abstract (sommario):

Abstract Clinical manifestations of alkaptonuria have been well described and are most commonly characterized by ochronosis or pigmentation of connective tissue. Sites most commonly involved in ochronosis include joints, heart, skin, and kidney. We describe a 66-year-old woman with a history of alkaptonuria who had widespread ochronosis. The dura mater showed extensive pigment deposition, which was evident both grossly and microscopically at autopsy.

Abstract (sommario):

Alkaptonuria is a rare inborn error of metabolism, which is classified as an orphan disease. It is due to the lack of an enzyme homogentisate 1,2-dioxygenase, which results in an accumulation of homogentisic acid in different areas of the body, including sclera, skin, cardiac valves, articular cartilage of the large joints and intervertebral disks. We present two cases of alkaptonuria resulting in ochronotic arthropathy with advanced secondary generalized osteoarthritis, intervertebral disk calcifications, skin and scleral pigmentation. In these case reports, both patients had symptoms for >10 years before being diagnosed. Conservative management in the form of high-dose ascorbic acid, exercises, and gait aids was offered to both of them, which resulted in some symptomatic improvement in the first case, while the second case was lost to follow-up. Alkaptonuria is a rare disease, and although it does not clearly impact mortality, early diagnosis may improve the quality of life.
