[Ti] Título:Primaquine in Plasma and Methemoglobinemia in Patients with Malaria Due to in the Brazilian Amazon Basin.

[Ab] Resumo:AbstractPrimaquine is the only licensed drug available for the elimination of hypnozoites. Methemoglobinemia is currently reported in the course of treatment. There is evidence that metabolites of primaquine formed by the cytochrome pathway are responsible for methemoglobin formation; a genetic polymorphism of cytochrome isoforms; and a potential influence of gender in the activities of these enzymes requiring the establishment of dose × response curves profiles in different population groups. Concentrations of primaquine in plasma and methemoglobin levels were investigated in 54 patients with malaria due to during the course of the standard regimen of chloroquine with primaquine (0.25 mg/kg/day for 14 days). All study subjects lived in an endemic area of the Brazilian Amazon Basin. The blood samples were collected before initiation of treatment and 3 hours (range 2-4 hours) after the administration of antimalarial drugs on days 2, 7, and 14. Plasma primaquine concentrations were similar in both genders (males: range = 164-191 ng/mL, females: range = 193-212 ng/mL). Methemoglobin levels ranged from 3.3% to 5.9% in males and from 3.1% to 6.5% in females. There were no significant correlations between the plasma primaquine concentrations or total dose and methemoglobin levels, suggesting that unidentified metabolites rather than parent drug were likely responsible for changes in methemoglobin levels. There was no significant influence of gender on primaquine concentrations in plasma or methemoglobin levels.

[Ab] Resumo:AIM OF THE STUDY: Combustion of organic tissues due to endoscopic resection could induce methemoglobin (MetHb) and carboxyhemoglobin (COHb) formation. The aim of this study is to evaluate MetHb and COHb formation in patients undergoing prostatic or bladder endoscopic procedures. METHODS: COHb and MetHb measurements were performed in 44 patients at the beginning and end of the procedure. A third measurement was done in patients who stayed more than one hour in the recovery room. Means were compared using Student t-test, simple regressions were used for quantitative variables and ANOVA for categorical variables. Multiple linear regressions were used for multivariate analysis. RESULTS: COHb increased by 0.5±0.9 % (95 % CI: 0.2 to 0.7 % P=0.001). MetHb increase was 0.0±0.4 % (95 % CI: -0.1 to 0.2 % P=0.552). In univariate analysis, the variables associated with COHb increase are the length of surgery, the amount of irrigation fluid and location (prostate or bladder) of the procedure. In the multivariate model, COHb increase is associated with the amount of liquid and the location. CONCLUSION: MetHb did not increase during endoscopic surgery. In contrast, COHb increases, and can, in some patients, exceed 2-4 %. This could be responsible for a decreased angina threshold in patients with ischemic heart disease. LEVEL OF EVIDENCE: 4.

[Ab] Resumo:Type I congenital methemoglobinemia is an autosomal recessive disorder. A high frequency of congenital methemoglobinemia has been reported among Native Americans inhabiting the Yukon-Kuskokwim Delta. Other rare cases of congenital methemoglobinemia of types I and II have been reported in Japan and other countries. In Russia-namely, in Yakutia-a high frequency of type I congenital methemoglobinemia has been reported. In 2009, the Consultation Polyclinic of the Pediatric Center in Yakutsk city established a registry of children with congenital methemoglobinemia. In total, 43 patients were registered between 2005 and 2009. The median methemoglobin level was 13.5% (ranging between 4.2% and 33.9%) and physical examination revealed cyanosis of the skin and mucus membranes. There were significant positive relationships between percentage of methemoglobin and erythrocyte count, hemoglobin concentration, and hematocrit among male patients, consistent with an upregulation of the hypoxic response. The prevalence per 100,000 children ranged from 12.7 to 47.0 in 3 geographic regions of Yakutia. Further research is needed to clarify the clinical consequences of congenital methemoglobinemia in the children of Yakutia and the reasons for the high variability in the prevalence of the condition.

[Ab] Resumo:The authors herein report a 5-year-old child who presented with massive hemolysis, irritability, and cyanosis. The final diagnosis was glucose-6-phosphate dehydrogenase deficiency with associated central nervous system symptoms probably because of concomitantly acquired methemoglobinemia following oxidant drug exposure. The associated acute-onset anemia would have contributed to the development of cerebral anoxia-related seizures and encephalopathy.

[Ab] Resumo:We report on the case of a young infant with chronic diarrhea that worsened and turned into hypovolemic shock with methemoglobinemia. We underline and discuss the main features of food protein-induced enterocolitis syndrome (FPIES). FPIES is a non-IgE-mediated food allergy involving tumor necrosis factor-alpha (TNF-α). Many triggering foods exist but cow's milk, as in the case reported herein, is one of the most frequent. It can start early or be delayed and start around the average age of 5 months. Symptoms are nonspecific with diarrhea and vomiting, but in the presence of methemoglobinemia, the diagnosis must be seriously considered. The oral food challenge remains the gold standard to confirm the diagnosis if there is still a doubt. Treatment of FPIES associates emergency treatment of acute dehydration with the prevention of relapses by avoiding the suspected protein.

[Ab] Resumo:OBJECTIVES: Congenital methemoglobinemia due to NADH-cytochrome b5 reductase 3 (CYB5R3) deficiencies is an autosomal recessive disorder that occurs sporadically worldwide, A sensitive, accurate, and rapid analysis of NADH-CYB5R enzyme concentrations is necessary for the diagnosis of RCM. Here we present an alternative microplate method that is based on a standard 96-well microplate format and microplate reader that simplify the quantification of NADH-CYB5R activity. METHODS: TECAN (Infinite 200 PRO series) microplate reader with Tecan's proven Magellan™ software measured the NADH-CYB5R enzyme activity in 250 normal controls and previously diagnosed 25 cases of RCM due to NADH-CYB5R deficiency in the Indian population using 96-well microplates using 200 µl of total reaction mixture and also compared with standard spectrophotometric assay. We have also studied stability of the hemolysate stored at 4 and -20°C temperature. RESULTS AND DISCUSSION: Enzyme activity in all 25 samples ranged from 6.09 to 10.07 IU/g Hb (mean ± SD: 8.08 ± 1.99 IU/g Hb) where as normal control ranged (n = 250) between 13.42 and 21.58 IU/g Hb) (mean ± SD: 17.5 ± 4.08 IU/g of Hb). Data obtained from the microplate reader were compared with standard spectrophotometer method and found 100% concordance using both methods. Microplate method allows differentiating between normal, deficient and intermediate enzyme activity. It was observed that samples had significant loss of activity when stored at 4°C and retained stable activity at -20°C for 1 week time. CONCLUSION: Our new method, incorporating a whole process of enzyme assay into a microplate format is readily applicable and allows rapid monitoring of enzyme assay. It is readily applicable to quantitative assay on pediatric sample as well as large number of samples for population screening.

[Ab] Resumo:A worker attempting to remove solidified material inside a confined space (storage tank) suffered severe methemoglobinemia and almost died. The tank contained liquid 4,4'-methylene diphenyl diisocyanate monomer that had solidified after an equipment power failure caused excessive heating. Wearing a full-face elastomeric air-purifying respirator and Tyvek® coveralls, the worker used pneumatic air hammers to break up the solid material. After two tank entries totaling slightly less than one hour, the worker complained of headache and dizziness and within two hours of exiting the tank, he was admitted to the hospital in severe respiratory distress. During his eight-week hospital course, he suffered a cardiac arrest among other complications. An investigation into the cause of the worker's illness used onsite gas chromatography-mass spectrometry which identified aniline and p-toluidine vapor within the tank, attributable to overheating that led to formation of the solid material. Both are well-known causes of methemoglobinemia, and had the initial characterization of the confined space atmosphere adequately identified the hazards present appropriate engineering controls and personal protective equipment could have allowed the tank entrant to work safely in the space.
