Published: October 2022

Intravascular hemolysis, which is the destruction of red blood cells in circulation, can cause acute kidney injury as the hemoglobin released by the lysed cells is toxic to the tubular epithelial cells. We performed a retrospective analysis of 56 cases of hemoglobin cast nephropathy reported at our institution to analyze the etiological spectrum causing this rare disease. The mean patient age was 41.7 (range: 2-72 years), and the male-to-female ratio was 1.8:1. All patients presented with acute kidney injury. The etiologies include rifampicin-induced, snake bite, autoimmune hemolytic anemia, falciparum malarial infection, leptospiral infection, autoimmune hemolytic anemia, sepsis, non-steroidal anti-inflammatory drugs, ingestion of termite oil, heavy metal poisoning, wasp sting, and valvular heart disease with severe mitral regurgitation. We demonstrate a wide spectrum of conditions associated with hemoglobin casts in the kidney biopsy. Hemoglobin immunostain is required to establish the diagnosis.

Malaria is an infectious disease caused by several types of parasitic plasmodia and transmitted to humans through Anopheles mosquitoes. The disease has long been widespread and has caused a significant number of deaths and decreased life quality from sequelae worldwide. As understanding of the disease increased immensely at the beginning of the 20th century, eradication plans were implemented to decrease disease transmission.

Beta-thalassemia (β-thalassemia) is a hematologic genetic condition that causes microcytic anemia due to defective synthesis of the hemoglobin beta chain. As a hypochromic microcytic anemia that is commonly associated with symptoms such as fatigue and pallor when identified in adulthood, β-thalassemia may be commonly underdiagnosed or misdiagnosed as iron deficiency anemia. This study presents a case of a patient with β-thalassemia who was initially misdiagnosed with treatment-resistant iron deficiency anemia.

Article Synopsis
  • Systemic lupus erythematosus (SLE) is an autoimmune disease that predominantly affects women, with ongoing research into why this gender disparity exists and how ethnicity may affect the disease's clinical features.
  • A study of 89 childhood-onset SLE patients revealed that males had more instances of serositis and elevated anti-DNA antibodies, while females experienced more hair loss and lower average hemoglobin levels.
  • Despite differences in treatment, renal involvement appeared more commonly in males, indicating a need for further exploration of gender-specific manifestations and treatments in cSLE cases.

Objective: Sickle cell anemia (SCA) is a hematological condition that involves the synthesis of sickle-shaped, hemoglobin with a short lifespan. This study employed three-dimensional (3D) scanning to pinpoint the most common arch form in a sample of Iraqi adults with SCA.

Materials And Methods: A cross-sectional study included maxillary and mandibular casts of 50 patients (25 male and 25 female) with SCA and 50 participants in a control group (25 male and 25 female).

Human Hemoglobin-Based Zinc-Air Battery in a Neutral Electrolyte.

Energy Fuels

December 2023

Departamento de Química Física y Termodinámica Aplicada, Instituto Químico para la Energía y el Medioambiente, Universidad de Córdoba, E-14014 Córdoba, Spain.

The use of human hemoglobin (Hb) as a catalytic component of the air electrode in a primary zinc-air battery with a neutral electrolyte has been investigated. Three different electrode modifications, using the drop-casting method, with Hb and Nafion were first tested in a three-electrode cell, obtaining the best oxygen electroreduction (ORR) performance and long-term stability with a Hb plus Nafion (Hb-Nafion)-modified electrode. The latter Hb-Nafion-based air electrode provided a higher specific capacity and discharge time than the opposite order (Nafion-Hb).
