Clostridial organisms occur in great numbers and distribution throughout the world. Because of this, they are very common in traumatic wounds. Very few species of Clostridia, however, are pathogenic, and still fewer are capable of producing gas gangrene in man.

Journal of Medical Case Reports (2019) 13:125 https://doi.org/10.1186/s13256-019-2023-x CASE REPORT Open Access A suspected case of Clostridium perfringens sepsis with intravascular hemolysis after transhepatic arterial chemoembolization: a case report Haruki Uojima1,2*, Mie Onoue2, Hisashi Hidaka2, Naohisa Wada2, Yoshiaki Tanaka2, Tomoyoshi Inoue2, Kousuke Kubota2, Takahide Nakazawa2, Akitaka Shibuya2 and Wasaburo Koizumi2 Abstract Introduction: Sepsis due to Clostridium perfringens, one of several clostridial species, is an important cause of massive intravascular hemolysis in patients with underlying malignancies. Chronic liver diseases, immunosuppression, and presence of malignancies were risk factors for Clostridium perfringens sepsis. Therefore, Clostridium perfringens sepsis should always be considered in patients presenting with liver damage after chemo- embolic therapy for hepatocellular carcinoma. This case report focuses on findings characteristic of an intravascular hemolysis due to Clostridium perfringens after transhepatic arterial chemoembolization. Case presentation: An 83-year-old Japanese man presented to our hospital because of a third recurrence of hepatocellular carcinoma. He had nonalcoholic steatohepatitis-related cirrhosis, and underwent radiofrequency ablation and transhepatic arterial chemoembolization therapy for hepatocellular carcinoma of S4/S8 and S2. He had a medical history of pancreatic carcinoma and underwent pylorus-preserving pancreaticoduodenectomy approximately 5 years ago. Because follow-up

  • Hemolytic Anemia: Evaluation and Differential Diagnosis
    Hemolytic Anemia: Evaluation and Differential Diagnosis James Phillips, MD, and Adam C. Henderson, MD, Womack Army Medical Center, Fort Bragg, North Carolina Hemolytic anemia is defined by the premature destruction of red blood cells, and can be chronic or life-threatening. It should be part of the differential diagnosis for any normocytic or macrocytic anemia. Hemolysis may occur intravascularly, extravascularly in the reticuloendothelial system, or both. Mechanisms include poor deformability leading to trapping and phagocytosis, antibody-mediated destruction through phagocytosis or direct complement activation, fragmentation due to microthrombi or direct mechanical trauma, oxidation, or direct cellular destruction. Patients with hemolysis may present with acute anemia, jaundice, hematuria, dyspnea, fatigue, tachycardia, and possibly hypotension. Laboratory test results that confirm hemolysis include reticulocytosis, as well as increased lactate dehydrogenase, increased unconju- gated bilirubin, and decreased haptoglobin levels. The direct antiglobulin test further differentiates immune causes from nonimmune causes. A peripheral blood smear should be performed when hemolysis is present to identify abnormal red blood cell morphologies. Hemolytic diseases are classified into hemoglobinopathies, membranopathies, enzymopathies, immune-mediated anemias, and extrinsic nonimmune causes. Extrinsic nonimmune causes include the thrombotic micro- angiopathies, direct trauma, infections, systemic diseases, and oxidative insults. Medications can cause hemolytic anemia through several mechanisms. A rapid onset of anemia or significant hyperbilirubinemia in the neonatal period should prompt consideration of a hemolytic anemia. (Am Fam Physician. 2018;98(6):354-361. Copyright © 2018 American Acad- emy of Family Physicians.) Hemolytic anemia is defined as the destruction of red and oxidation. Direct cellular destruction is caused by blood cells (RBCs) before their normal 120-day life span.
