Drug induced immune hemolytic anemia

Drug-induced hemolytic anemia is a rare hematologic condition in which the immune system creates antibodies against red blood cell antigens in response to a medication exposure. This condition is commonly triggered by antibiotics, nonsteroidal anti-inflammatory drugs, and certain chemotherapies. Here, we describe a patient who experienced a repeat episode of drug-induced hemolytic anemia related to prophylactic cefotetan given before surgery. This case is important for increasing awareness of cephalosporin-induced hemolytic anemia, illustrating the significance of early detection and treatment of the condition, and highlighting the need for careful review of medication history in the surgical setting...

The hematological impacts of a drug can affect erythropoiesis at the level of the bone marrow, or decrease the life span of the RBC (red blood cell). The most common and recognizable clinical manifestation of either type of drug-induced erythropoietic injury is a decrease in RBC mass, or what is clinically referred to as an anemia. A decrease in RBC production can generally be separated from increased destruction (hemolysis) by evaluation of the hemogram for evidence of regeneration. In most healthy mammalian species, hemolysis will result in a regenerative response characterized by an increase in circulating reticulocytes...

Background: Drug-induced immune hemolytic anemia (DIIHA) is a rare but potentially life-threatening drug-related complication. There are no previous reports of pemetrexed plus cisplatin as first-line chemotherapy for non-small cell lung cancer, resulting in DIIHA. Case presentation: In this report, a patient with advanced-stage lung adenocarcinoma developed severe immune hemolytic anemia 21 days after pemetrexed plus cisplatin chemotherapy. Laboratory findings showed severe hemolysis, including a rapid decrease in hemoglobin (HGB) and an elevated level of reticulocytes (Rets), indirect bilirubin (IBIL), and lactate dehydrogenase (LDH)...

Autoimmune hemolytic anemia (AIHA) is a rare disease characterized by autoantibodies directed at red blood cells. Patients typically present with anemia and are diagnosed by positive direct antiglobulin (DAT) test. AIHA is subclassified into warm or cold based on antibodies involved and depending on their optimal temperature in which they react with RBC antigens. Warm AIHA can be either primary (idiopathic) or secondary depending on etiology. Secondary causes are associated with malignancy, connective tissue and inflammatory diseases, infections (typically viral infections), or drugs (e...

BACKGROUND Pneumocystis jirovecii pneumonia (PJP) is an opportunistic infection that commonly occurs in immunocompromised patients, especially those with HIV. Early diagnosis and prompt treatment are important because PJP is a potentially life-threatening infection. However, the diagnosis of PJP in the early stage can be challenging due to various factors. Furthermore, the early presentation of PJP, which includes normal chest radiograph and examination findings along with the subacute presentation of PJP in patients with HIV, makes an early diagnosis of the disease even more challenging for doctors...

We report the first case of immune complex type hemolytic anemia by initial micafungin administration that was given as prophylaxis to a 42-year-old Japanese man receiving chemotherapy for primary amyloidosis. The few cases found in the literature were associated with secondary administration to cause immune hemolysis attacks. Despite its rarity, the present case calls for increased awareness of micafungin-induced hemolytic anemia upon initial administration.

Drug-induced immune thrombocytopenia (DITP) refers to drug-dependent, antibody-mediated platelet destruction. Although several drugs have been implicated as the cause of DITP, the most commonly encountered are heparin, sulfonamides, quinine, vancomycin, and beta-lactam antibiotics. However, furosemide has been rarely reported as the cause of thrombocytopenia. We present a unique case of furosemide-induced thrombotic thrombocytopenia in a 64-year-old female referred by her primary care provider for low platelets, rash, and bleeding...

PURPOSE: The simultaneous occurrence of cerebral toxoplasmosis and cryptococcosis is rare. The infections continue to be treated with sulfadiazine and amphotericin-B-based regimens (preferred therapy), respectively. Both these drugs are linked to some serious adverse drug reactions (ADRs). We report such a unique instance of both; the CNS co-infections and adverse drug reactions to the preferred therapy. CASE PRESENTATION: A 44-year-old Asian-Indian female was diagnosed with cerebral toxoplasmosis, impending cryptococcal meningoencephalitis, and acquired immune deficiency syndrome (AIDS)...

For patients with autoimmune diseases, vaccination is controversial. The use of vaccination in patients with autoimmune diseases is controversial. There are many reports of secondary thrombotic thrombocytopenic purpura cases after various vaccinations. Thrombotic thrombocytopenic purpura is a rare thrombotic microangiopathy characterized by microvascular pathological hemolytic anemia, severe thrombocytopenia, and ischemic organ damage with a very high fatality rate. We report a case of thrombotic thrombocytopenic purpura in a patient with systemic lupus erythematosus after rabies vaccination...

The liver is the largest organ of the body weighing 1-1.5 kg, which is 1.5-2.5% of the lean body mass. It plays a major role in protein synthesis, nutrient regulation, metabolism, and the combination of bilirubin and drugs, detoxification, bile production, and immune maintenance. Pathogenesis of hematological changes is multifactorial and included portal hypertension induce sequestration, alteration in bone marrow stimulating factors, viral and toxin-induced bone marrow suppression. Anemia of diverse etiology occurs in about 75% of patients of CLD...

Lutetium-177 (177 Lu) dotatate is a type of peptide receptor radioligand therapy (PRRT) using radiolabeled somatostatin for patients with progressive somatostatin receptor-positive gastrointestinal neuroendocrine tumors. While cases of therapy-related myeloid neoplasms (t-MN) have been described as a consequence of 177 Lu dotatate, there are no reports of hemolytic anemia associated with therapy. We present a case of a 68-year-old woman with metastatic low-grade neuroendocrine tumor who presented four weeks after the second dose of 177 Lu dotatate with progressive fatigue and dyspnea...

Identification of new disease-associated biomarkers; specific targeting of such markers by monoclonal antibodies (mAbs); and application of advances in recombinant technology, including the production of humanized and fully human antibodies, has enabled many improved treatment outcomes and successful new biological treatments of some diseases previously neglected or with poor prognoses. Of the 110 mAbs preparations currently approved by the FDA and/or EMA, 46 (including 13 antibody-drug conjugates) recognizing 29 different targets are indicated for the treatment of cancers, and 66, recognizing 48 different targets, are indicated for non-cancer disorders...

A 69-year-old female with a history of psoriatic arthritis was diagnosed with septic arthritis and started on broad-spectrum antibiotics. She underwent left hip excisional debridement of her prosthetic hip joint which grew group B Streptococcus ( S. agalactiae ). She was switched to IV ceftriaxone 2 g daily and her hemoglobin decreased to 5.4 g/dL on day 11. Peripheral blood smear showed normochromic normocytic anemia and thrombocytopenia without the presence of schistocytes. Increased lactate dehydrogenase (LDH), decreased haptoglobin and hemoglobin, and positive direct Coombs test (DCT) led to a presumptive diagnosis of drug-induced immune hemolytic anemia (DIIHA)...

Chronic lymphocytic leukemia (CLL) patients have a greater predisposition to develop autoimmune complications. The most common of them is autoimmune hemolytic anemia (AIHA) with a frequency of 7-10% of cases. Pathogenesis is multifactorial involving humoral, cellular, and innate immunity. CLL B-cells have damaged apoptosis, produce less immunoglobulins, and could be responsible for antigen presentation and releasing inflammatory cytokines. CLL B-cells can act similar to antigen-presenting cells activating self-reactive T helper cells and may induce T-cell subsets imbalance, favoring autoreactive B-cells which produce anti-red blood cells autoantibodies...

Autoimmune thrombocytopenia (ITP) and autoimmune hemolytic anemia (AIHA) can be observed in Waldenström macroglobulinemia (WM). The autoimmune disorders are primarily mediated by autoimmune monoclonal gammopathy, but drug-induced hemolysis should also be considered. Herein, we presented the case of a 63-year-old female WM patient complicated with ITP, who was admitted to our department with a complaint of abdominal pain. After first half of bortezomib/dexamethasone/rituximab (BRD) chemotherapy, her platelet level recovered, but subsequently decreased to extremely low level (around 1-2×109 /L), and the patient suffered from platelet transfusion refractoriness...

OBJECTIVE: To report a case of drug-induced immune hemolytic anemia (DIIHA) that was suspected to have been caused by cefmetazole. CASE SUMMARY: A 93-year-old woman with no previous history of liver complications underwent a contrast-enhanced computed tomography scan, which resulted in a diagnosis of acute cholecystitis. The patient experienced intravascular hemolysis and rapid progression of anemia after being exposed to 2 g/day of cefmetazole. After 48 hours of cefmetazole administration, the patient was transferred to the intensive care unit (ICU) of our facility...

Previously, it was reported that multiple patients had hemolytic anemia associated with cimetidine administration, while only one patient who had received intravenous cimetidine was serologically diagnosed with drug-induced immune hemolytic anemia (DIIHA) caused by cimetidine-dependent antibodies. However, the ability of oral cimetidine intake to induce the production of antibodies has not been examined. In this study, we report a 44-year-old male patient in whom oral cimetidine administration resulted in cimetidine-dependent antibodies and drug-independent non-specific antibodies, leading to the development of DIIHA...

BACKGROUND: Transfusion of red blood cells (RBCs) stored for longer durations induces hemolysis and inflammatory cytokine production in murine and canine models. Despite immune system activation by stored RBCs, human randomized trials suggest that fresher RBC transfusions do not improve clinical outcomes. We hypothesized that underlying recipient hemolysis may affect cytokine responses to older RBC transfusions. STUDY DESIGN AND METHODS: C57BL/6 mouse cohorts were infused with anti-TER119 antibody to induce hemolysis, rabbit anti-platelet antiserum to induce immune thrombocytopenia (ITP), or appropriate control antibodies...

Drug-induced immune hemolytic anemia is an exceedingly rare adverse drug event. Thiazide diuretics, commonly used in the treatment of primary hypertension, have been associated with this complication. In this case report, we present a 77-year-old male who developed acute hemolytic anemia two days after starting hydrochlorothiazide in the treatment of high blood pressure.

Introduction: Crohn's disease (CD) is an idiopathic inflammatory disorder of unknown etiology with genetic, immunologic, and environmental influences. Infliximab is a treatment modality for fistulated Crohn's disease. Infliximab induced hemolysis is rare and very few cases reported before in Ulcerative colitis (UC) but not in Crohn's disease . Case presentation: We are reporting a 63 years old gentleman who was diagnosed as Crohn's disease and started on Tumor necrosis factor Inhibitor (TNF) -α i...
