Summary
This review explores renal thrombotic microangiopathy in rheumatologic diseases. Systemic lupus erythematosus is a common cause, alongside scleroderma renal crisis and antiphospholipid antibody syndrome.
Area of Science:
- Nephrology
- Rheumatology
- Hematology
Background:
- Thrombotic microangiopathies (TM) are complex conditions causing anemia, low platelets, and kidney damage.
- Causes are diverse, including metabolic, infectious, medication-related, complement, pregnancy, malignancy, and autoimmune factors.
Purpose of the Study:
- To review the specific causes and clinical features of renal thrombotic microangiopathy within the context of rheumatologic diseases.
- To highlight the association between TM and autoimmune conditions.
Main Methods:
- Literature review focusing on thrombotic microangiopathy and rheumatologic conditions.
- Analysis of case reports and existing studies.
Main Results:
- Systemic lupus erythematosus is the most frequent autoimmune disease linked to TM.
- Scleroderma renal crisis and antiphospholipid antibody syndrome are significant causes, often secondary to autoimmune diseases.
- TM has been reported in rheumatoid arthritis and dermatomyositis.
Conclusions:
- Rheumatologic diseases represent a critical category of causes for renal thrombotic microangiopathy.
- Early recognition and management of TM in rheumatologic patients are essential for renal outcomes.

Antigens Involved in Adaptive Immunity
1.5K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Chemical Equations
81.6K
Chemical equations represent the identities and relative quantities of substances involved in a chemical reaction. The substances undergoing reaction are called reactants, and their formulas are placed on the left side of the equation. The substances generated by the reaction are called products, and their formulas are placed on the right side of the equation. Plus signs (+) separate individual reactant and product formulas, and an arrow (→) separates the reactant and product (left and right)...

Peptide Bonds
83.1K
A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...

Bacterial Signaling
40.8K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Protein-protein Interfaces
14.7K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...
