Arsenic (As) is a semimetal that can exist in inorganic, organic, or gaseous forms in nature. Management of acute promyelocytic leukemia: recommendations from an expert panel on behalf of the European LeukemiaNet. Chemotherapy-Induced Peripheral Neuropathy: A Review and Implications for Oncology Nursing Practice. Prior to the start of therapy, all patients had a complete blood cell count (CBCs); coagulation profiles, including prothrombin time, partial thromboplastin time, fibrinogen, fibrin split products, and D‐dimer; blood chemistry, including total protein, albumin, calcium, inorganic phosphorus, blood urea nitrogen, creatinine, glucose, uric acid, total bilirubin, alkaline phosphatase, lactate dehydrogenase, and alanine aminotransferase; electrolytes; urinalysis; electrocardiogram (EKG); chest X‐ray; and bone marrow aspiration with cytogenetic analysis and/or molecular or FISH studies, if indicated. In natural waters arsenic normally occurs in the oxidation states +III (arsenite) and +V (arsenate). As2S3: (arsenic oxidation state) Let oxidation no of arsenic be x. In AsH3, arsenic has oxidation number -3, but in AsF3, arsenic has oxidation number +3. All patients received additional therapy after achieving a CR (Table 3). Three patients have developed recurrent disease: One patient developed recurrent disease after 29 weeks, having received 3 cycles of As2O3 as maintenance therapy; he later achieved a third CR with oral ATRA. 0 0. bala. Arsenic (+3 oxidation state) methyltransferase (AS3MT) is a key enzyme responsible for arsenic metabolism in humans, which facilitates conversion of arsenic trioxide (As2O3) to more reactive metabolites such as monomethylarsonous acid (MMAIII) and dimethylarsinous acid (DMAIII). In com­pounds, ar­senic can dis­play 3 ox­i­da­tion states - -3, +3 и +5. trans Arsenic 2. 2018 Nov 1;166(1):219-227. doi: 10.1093/toxsci/kfy210. The toxicity profile of As2O3 was favorable. The most frequent adverse events include peripheral neuropathy, headache, fatigue, and rash. The patient who presented in third recurrence was treated originally with ATRA, achieved a CR, and developed a recurrence after 168 weeks. The current results compare favorably with those obtained with ATRA as salvage therapy. 2018 Oct 15;357:80-87. doi: 10.1016/j.taap.2018.08.020. Later, this patient achieved a CR with allogenic bone marrow transplantation. Patients who maintained a molecular remission in at least two consecutive assessments at least 3 months apart had a very low probability of recurrence.17, The mechanism of action of As2O3 is not understood well. As2O3 is effective and well tolerated therapy for patients with recurrent APL. After a median follow‐up of 98 weeks (range, 37–181 weeks), 8 patients (67%) were alive and in CR at the time of this report (Fig. The removal of As(III) is more difficult than the removal of As(V). Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers). Sign In Create Free Account. There is little information on the frequency of molecular remissions with ATRA alone, because this agent is used most frequently in combination with chemotherapy during induction. Its minimum oxidation state we can predict as being -3, and its maximum as +5 Side effects were mild, except for two patients who developed Grade 2 and 3 peripheral neuropathy, respectively; one of those patients required discontinuation of therapy. All 12 patients achieved CR. Arsenic (+3 oxidation state) methyltransferase (AS3MT) is a key enzyme responsible for arsenic metabolism in humans, which facilitates conversion of arsenic trioxide to more reactive metabolites such as monomethylarsonous acid (MMAIII) and dimethylarsinous acid (DMAIII). 2010 Jul 13;18(1):88-98. doi: 10.1016/j.ccr.2010.06.003. Treatment concepts of acute promyelocytic leukemia. Approximately 20–30% of patients with acute promyelocytic leukemia (APL) who are treated with all‐trans retinoic acid (ATRA) and an anthracycline develop recurrent disease. Clinically, patients with APL present with a unique tendency to disseminated intravascular coagulopathy, which increases their morbidity and mortality during induction.1 The current standard treatment for patients APL consists of all‐trans retinoic acid (ATRA) and an anthracycline with or without cytarabine. Favourite answer. 9 years ago. As2O3 appears to be a safe and effective agent for the treatment of patients with APL. The median duration of induction therapy was 42 days (range, 27–60 days). EKGs were required weekly, and bone marrow aspirates were repeated to assess response. initially reported on 15 patients with recurrent APL who were treated with As2O3. The occurrence of hyperleukocytosis with As2O3 treatment seriously affects the early survival rate of APL patients, but no definite explanation for such a complication has been clearly established. Other side effects during maintenance included Grade 1 headache (n = 2 patients), fatigue (n = 2 patients), and rash (n = 1 patient). Arsenic trioxide and ascorbic acid demonstrate promising activity against primary human CLL cells in vitro. Efficacy of Transarterial Embolization with Arsenic Trioxide Oil Emulsion in a Rabbit VX2 Liver Tumor Model. Arsenic trioxide: safety issues and their management. in vitro Oxidation number is the property of an element in a chemical form. +1, +2, +3, +4, or +5? Still, is important that patients who are treated with As2O3 are monitored closely for cardiac and electrolyte abnormalities. Molecular remission may be achieved at the time of CR in the majority of patients, and remissions are durable. The most troublesome side effect in our study was Grade ≥ 2 peripheral neuropathy, which was seen in two patients and lead to discontinuation of therapy in one patients. The human and African green monkey TRIM5  genes encode Ref1 and Lv1 retroviral restriction factor activities. Survival was measured from the time of treatment until death. Brief History of Arsenic Discovery History is convoluted Not sure who first discovered Greeks and Romans had slaves mine for arsenic Used in Alchemy Albertus Magnus www.en.wikipedia.com German chemist First to isolate in 1250 AD Most of the toxicities identified in this study and others using As2O3 have been transient and minor. In addition, patients with the AS3MT 14215 (rs3740390) CC genotype had significantly higher plasma iAs% and incidence of hyperleukocytosis, but lower PMI than patients with the CT + TT genotype.
