Glucose-6-phosphate dehydrogenase deficiency: not exclusively in males

Glucose‐6‐phosphate (G6PD) deficiency is the most common human enzyme defect, often presenting with neonatal jaundice and/or acute hemolytic anemia, triggered by oxidizing agents. G6PD deficiency is an X‐linked, hereditary disease, mainly affecting men, but should also be considered in females with an oxidative hemolysis.

A rare case of acute pancreatitis and life-threatening hemolytic anemia associated with Epstein-Barr virus infection in a young healthy adult

Epstein-Barr virus (EBV) is a common infection that affects 95% of adults worldwide at some point during life. It is usually asymptomatic or causes a self-limiting clinical syndrome known as infectious mononucleosis. It rarely causes complications. Here, we present a case of a healthy 21-year-old female college student who suffered from severe pancreatitis and life-threatening autoimmune hemolytic anemia in association with EBV infection, and we also discuss the common presentation of EBV infection and the diagnosis and treatment of simple and complicated EBV infection.

Positive Impact of Clinical Audit on Appropriateness of Laboratory Investigations for Glucose-6-Phosphate Dehydrogenase-Deficient Patients in the Emergency Department

OBJECTIVES

The authors aim to assess the use of investigations for patients with acute hemolytic anemia due to glucose-6-phosphate dehydrogenase (G6PD) deficiency and to ensure guidelines application during practice to reduce the misuse of hospital resources in the emergency department (ED).

METHODS

A cross-sectional study was conducted at a pediatric tertiary hospital on children presenting to the ED with an acute hemolytic crisis due to G6PD deficiency. Initial investigations were collected from patients' records and compared to local hematology unit guidelines. After a period of basic training and guideline dissemination to the residents, a re-audit was conducted. Percentages of the requested investigations in each audit were calculated and compared using Chi-square test.

RESULTS

Fifty-three acute hemolytic anemia patients were included in the initial audit and 58 patients in the re-audit. In the initial audit, the most commonly requested nonindicated investigations were the Coombs test and liver enzymes. The requested nonindicated chemistry labs dropped from 74% in the initial audit to 14% in the re-audit (p < 0.001), and Coombs test from 81% to 12% (p < 0.001).

CONCLUSIONS

A large proportion of requested investigations for children presenting with G6PD acute hemolytic crisis are nonindicated. Education of medical staff about the guidelines and their continuous assessments through audits were effective at reducing unnecessary diagnostic tests.

Interesting case of G6PD deficiency anemia with severe hemolysis

Severe hemolysis was observed in a critically ill patient with G6Pd deficiency where the causative trigger could not be identified. We describe one young patient with severe hemolysis treated with two cycles of plasmapheresis which proved to be an effective tool in the treatment. The patient presented with diffuse pain abdomen, vomiting, yellowish discoloration of sclera and skin and acute breathlessness. Hemoglobin 5.4 mg/dl and total (T) serum bilirubin 17.08 mg/dl: Direct (D) 4.10 mg/dl and Indirect (I) 12.98 mg/dl. Subsequently patient started passing black color urine. As the patient developed severe hemolysis and the trigger agent of hemolysis was unknown, two cycles of plasmapheresis were performed with the aim to remove unknown causative agent. Consequently no trace of hemolysis was found and patient stabilized. Plasmapheresis can be used to treat G6PD deficient patients with severe hemolysis due to unidentified trigger agent.

Clostridium Perfringens Bacteremia with Acute Hemolytic Anemia in the Setting of Endometrial Malignancy

Acute intravascular hemolysis is a rare and often lethal complication of Clostridium perfringens septicemia.Clostridium perfringens is an anaerobic, gram-positive spore-forming rod which is commonly implicated in cases of food poisoning, gas gangrene, and severe hemolytic anemia in humans via the alpha-toxin (phospholipase C). We report an interesting and rare case of a 72-year-old woman who developed massive intravascular hemolysis secondary to C perfringens bacteremia in the setting of poorly differentiated high-grade endometrial malignancy.
