delta-Aminolevulinic acid dehydratase deficiency porphyria (ALAD porphyria, ADP) with syndrome of inappropriate secretion of antidiuretic hormone (SIADH) in a 69-year-old woman is reported. The patient was admitted to our hospital complaining of slight cough with low-grade fever, and treated with
Aminolevulinic acid (ALA) is being used as a "prodrug" for photodynamic therapy. The side effects of ALA have been only anecdotally reported and these effects as well as pharmacokinetics of the photosensitizing end product of ALA, protoporphyrin IX (PpIX), in patients undergoing operation are
Intravenous lead administration to dogs produced an acute syndrome of lead intoxication charcterized by depression, vomiting, anorexia and weight loss. The effect of chelation therapy with calcium disodium ethylene diamine tetraacetate, penicillamine or both was determined by serially monitoring
BACKGROUND
Photochemical and thermal methods are used for ablating Barrett's oesophagus (BO). The aim of this study was to compare 5-aminolevulinic acid induced photodynamic therapy (ALA-PDT) with argon plasma coagulation (APC) with respect to complete reversal of BO.
METHODS
Patients with BO (32 no
As a prelude to photodynamic therapy, 5-aminolevulinic acid (ALA) was given orally to healthy dogs. ALA-induced protoporphyrin IX (PpIX) fluorescence significantly increased in the mucosa of the urinary bladder in an ALA dose-dependent fashion. Vomiting occurred after ALA administration in 70% of
BACKGROUND
The usefulness of 5-aminolevulinic acid (5-ALA) for resection of malignant astrocytomas has been established in recent years. In addition to these tumors, it has been reported that 5-ALA fluorescence could be elicited in other tumors such as intracranial and spinal meningiomas or
Background: 5-Aminolevulinic acid (ALA)-mediated photodynamic diagnosis (PDD) had recently been approved in Japan for the management of non-muscle invasive bladder cancer. As such, the current study aimed to investigate the real-world
Photodynamic therapy (PDT) using 5-aminolevulinic acid (ALA)-induced protoporphyrin IX (PpIX) may have a role in the treatment of dysplastic Barrett's esophagus. Before ALA-induced PDT can be used clinically, optimum treatment parameters must be established. In this study of 35 patients, the issues
The porphyrias are a group of rare metabolic disorders, inherited or acquired, along the heme biosynthetic pathway, which could manifest with neurovisceral and/or cutaneous symptoms, depending on the defective enzyme. Neurovisceral porphyrias are characterized by acute attacks, in which excessive
A 44-year-old woman complained of abdominal pain of 4 days' duration accompanied by vomiting and painful urination. The admitting physician noted neurologic signs consistent with axonal polyneuropathy and hyponatremia. In the absence of other explanations for the syndrome, SIADH was diagnosed.
Acute porphyrias are caused by the inherited decreased activity of the enzymes of the heme biosynthesis pathway. Depending on the affected enzyme there are 4 types of them: acute intermittent porphyria, porphyria variegata, coproporphyria and delta-aminolevulinic acid dehydratase deficient
Although the incidence of lead toxicosis in small animals continues to decrease, it remains a significant malady. We have reviewed the literature of the past 45 years, which revealed 70 cases involving cats. Sources, signs, diagnosis, pathology and treatment of feline lead toxicosis are reviewed. In
Porphyrias, particularly acute intermittent porphyria (AIP), are rare disorders which could be associated with systemic lupus erythematosus (SLE). Although the association with AIP has been known since 1952, only 11 cases have been published to date. It is widely known that precipitating causes such
BACKGROUND
Hereditary tyrosinemia type 1 (HT1) is a rare autosomal recessive inborn error of metabolism caused by deficiency of fumarylacetoacetate hydrolase. HT1 manifests with severe liver and kidney impairment and associates with an increased risk of liver cancer development. The aim of our study
Acute intermittent porphyria is caused by an inherent error of porphyrin metabolism characterized by a deficiency of porphobilinogen deaminase and increased activity of delta-aminolevulinic acid synthase, key enzymes necessary for the biosynthesis of heme. During an attack patients may have
