BACKGROUND: The rhesus (Rh) system is the second most important blood group system after ABO, with highly immunogenic antigens. Although the anti-E Rh antibody has been reported to cause hemolytic disease of the newborn and delayed hemolytic transfusion reactions, acute hemolytic transfusion reactions (AHTR) have been rarely reported. METHODS: Peripheral blood (PB) samples were screened for irregular antibodies using a commercial ID-Diacell I - II antibody screening Panel (Bio-Rad Laboratories, Glattbrugg, Switzerland) and ID-cards "LISS/Coombs" (Bio-Rad, Switzerland)...

Hereditary spherocytosis (HS) is a common heterogeneous type of inherited hemolytic anemia characterized by jaundice and splenomegaly. Diagnosis of HS in neonates is considered unreliable, and is generally based on positive family history, spherocytes in peripheral smears, increased osmotic fragility, and jaundice. In the present study, routine laboratory tests, next‑generation sequencing, and Sanger sequencing were applied to diagnose a neonatal patient with Coombs‑negative hemolytic jaundice. The neonate had no family history of HS; however, spherocytes were observed in peripheral smears, and the patient exhibited Coombs‑negative and severe hemolytic jaundice, normal mean corpuscular hemoglobin concentration (MCHC) and mean corpuscular volume (MCV), normal glucose‑6‑phosphate dehydrogenase activity, negative thalassemia genetic mutation screening results, and negative autoimmune antibody tests...

Paroxysmal nocturnal hemoglobinuria (PNH), a rare benign hematological disorder, presents with a wide variety of clinical symptoms. A direct Coombs-negative hemolytic anemia combined with an increased LDH = Lactate dehydrogenase level are signs to test for PNH. Follow-up does not need any microscopic review's only flow cytometric PNH clone size.

Autoimmune hemolytic anemia (AIHA) is a very rare cause of anemia in a case of malaria and drug-induced AIHA is even rarer. A 50-year old patient with a history of fever for 8 days was diagnosed with a case of complicated malaria with mixed infection having initial parasite index of 45%. He showed good response on initial therapy with artesunate (parasite count reduced to <1%) but his haemoglobin (Hb) continued to drop from 12 g% to 4.9 g% over a course of 11 days. Direct coombs test was positive with reduced haptoglobin and increased lactate dehydrogenase suggesting AIHA...

We determined the clinical utility of the direct Coombs' test in the absence of hemolytic anemia as an indicator of disease activity and therapeutic response in systemic lupus erythematosus (SLE). SLE patients without hemolytic anemia who visited our hospital from January 2016 to November 2016 were retrospectively evaluated with a direct Coombs' test. Clinical features, including SLE disease activity index (SLEDAI), treatment and laboratory findings were analyzed. For patients with lupus nephritis, we additionally evaluated the cumulative complete renal response rate over one year after induction therapy...

Hemolytic uremic syndrome (HUS) is the triad of nonimmune (Coombs negative) hemolytic anemia, low platelet count, and renal impairment. HUS has been associated with a variety of gastrointestinal malignancies and chemotherapeutic agents. We present a patient with pancreatic cancer treated with gemcitabine for palliation who developed gemcitabine-induced HUS (GiHUS) which responded to some extent to blood and platelet transfusions. With the increase in the use of gemcitabine therapy for pancreatic and other malignancies, it is essential to accurately and timely diagnose GiHUS to avoid the life-threatening complications...

BACKGROUND: Cold agglutinin disease is a very rare condition associated with agglutination of erythrocytes in cold environment usually due to IgM type antibodies. Other than hemolytic anemias, it may interfere with routine hemogram tests due to miscalculation of red blood cell count (RBC) and other hemogram parameters calculated with involvement of RBC. Awareness of the condition is important to overcome laboratory errors. METHODS: We studied a peripheral blood smear and repeated the hemogram test at 37°C to establish the diagnosis of cold agglutinin disease...

A 68-year-old woman was referred to our hospital due to fever and rash on the neck and extremities. Laboratory findings revealed hepatic dysfunction and positivity for anti-mitochondrial M2 antibody (AMA-M2). Hepatosplenomegaly and systemic lymphadenopathy were detected by enhanced computed tomography. One week after her first visit, hypoxemia, ascites, and Coomb test-positive autoimmune hemolytic anemia had newly appeared in addition to worsened fever, hepatosplenomegaly, and lymphadenopathy. Results of axillary lymph node, skin, and bone-marrow biopsies led to the diagnosis of angioimmunoblastic T-cell lymphoma (AITL), for which CEPP therapy (cyclophosphamide, etoposide, procarbazine, and prednisolone) was initiated...

Hereditary spherocytosis (HS) is a congenital hemolytic anemia that affects the cell membrane of red blood cells and is characterized by the presence of spherical-shaped erythrocytes in the peripheral blood film. The clinical manifestation of HS ranges from asymptomatic to severe cases that require transfusion during early childhood. HS is caused by mutations in red blood cell membrane protein encoding genes, including ANK1, EPB42, SLC4A1, SPTA1, and SPTB. Mutations of the ANK1 gene account for 75% of all HS cases, and these particular mutations are typically inherited in an autosomal dominant manner...

Wilson disease (WD) is a rare and treatable genetic disorder. This paper describes the new advances and author's long-term experiences in the diagnosis of WD. The characteristics in clinical and routine tests are: the age of presentation can be quite broad, the WD could not be excluded based on age only; the patients usually have mild digestive symptoms but obvious chronic liver disease signs; liver function tests may reveal normal or a mild elevation in bilirubin, ALT and AST, but quite abnormal in serum albumin and prothrombin time in most patients; Coombs-negative hemolytic anemia, normal or markedly subnormal serum alkaline phosphatase (typically < 40 IU/L) are useful for the diagnosis of fulminant WD...

An 80-year-old male presented with dyspnea on exertion for at least two months. He also complained of progressive dysphagia and weight loss of 35 pounds over the last eight months. Initial blood tests showed hemoglobin of 6.1 g/dl, reticulocytes count of 19.7%, total bilirubin of 3.2 mg/dl, lactate dehydrogenase of 600 U/L, and haptoglobin of less than 8 mg/dl, and direct Coombs test was positive for warm immunoglobulin G. The impression was autoimmune hemolytic anemia (AIHA). The evaluation of dysphagia with esophagogastroduodenoscopy revealed a single irregular 4 cm malignant appearing ulcerated mass at the incisura angularis of the stomach...
