Overview of neonatal lupus
Summary
Neonatal lupus (NL) involves maternal autoantibodies affecting the fetus, with congenital heart block being a severe risk. Current treatments include prenatal steroids, with newer therapies combining them with IVIG and plasmapheresis.
Area of Science:
- Immunology
- Pediatrics
- Obstetrics
Background:
- Neonatal lupus (NL) arises from maternal autoantibodies crossing the placenta.
- These antibodies, including anti-Sjögren syndrome-A and anti-Sjögren syndrome-B, target fetal tissues.
- Congenital complete heart block is the most critical manifestation of NL.
Purpose of the Study:
- To provide an overview of neonatal lupus presentation.
- To discuss current and emerging therapeutic strategies for NL.
- To offer guidelines for diagnosing NL in newborns with specific symptoms.
Main Methods:
- Review of existing literature on neonatal lupus.
- Analysis of current treatment protocols for congenital heart block in NL.
- Synthesis of diagnostic criteria and management approaches.
Main Results:
- Prenatal steroids are a primary therapy for reversing or preventing progression of congenital heart block.
- Combination therapies involving steroids, IVIG, and plasmapheresis show promise.
- NL can affect multiple fetal systems, including skin, heart, and neurological functions.
Conclusions:
- Neonatal lupus requires consideration in fetuses and newborns with maternal autoantibodies.
- Early diagnosis and intervention are crucial for managing NL manifestations, especially congenital heart block.
- Multimodal therapeutic approaches are advancing NL management.

1.2K
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

32
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
