Neuropsychiatric systemic lupus erythematosus or NPSLE refers to the neurological and psychiatric manifestations of systemic lupus erythematosus. SLE is a disease in which the immune system attacks the body's own cells and tissues. It can affect various organs or systems of the body. It is estimated that over half of people with SLE have neuropsychiatric involvement. [1]

Contents

Classification

The American College of Rheumatology (ACR) has outlined 19 syndromes that are seen in NPSLE. These syndromes encompass disorders of the central and peripheral nervous systems: [2]

Each of the 19 syndromes are also stand-alone diagnoses, which can occur with or without lupus.

The majority of cases involve the central nervous system (CNS), which consists of the brain and spinal cord. [2] The most common CNS syndromes are headache and mood disorder. [1]

Though neuropsychiatric lupus is sometimes referred to as "CNS lupus", it can also affect the peripheral nervous system (PNS). Between 10-15% of people with NPSLE have PNS involvement. [3] Mononeuropathy and polyneuropathy are the most common PNS syndromes. [1]

Other syndromes

Some neurological syndromes outside of the ACR classification may also be considered NPSLE manifestations. These include neuromyelitis optica, posterior reversible encephalopathy syndrome, small fiber neuropathy, [4] and Lambert–Eaton myasthenic syndrome. [5]

Pathogenesis

There are several possible mechanisms that underlie the nervous system manifestations of lupus. Specific syndromes may be vasculopathic, autoantibody-mediated, or inflammatory in nature.

There is evidence that the blood–brain barrier, which protects the central nervous system, is compromised in patients with NPSLE. As a result of this, autoantibodies are able to infiltrate the CNS and cause damage. [6]

Diagnosis

For diagnosis of NPSLE, it must be determined whether neuropsychiatric symptoms are indeed caused by SLE, whether they constitute a separate comorbid condition, or whether they are an adverse effect of disease treatment. In addition, onset of neuropsychiatric symptoms may happen prior to the diagnosis of lupus. [7] Due to the lack of uniform diagnostic standards, statistics about NPSLE vary widely. [8]

Tests which aid in diagnosis include MRI, electrophysiological studies, psychiatric evaluation, and autoantibody tests. [9]

Treatment

Management of neuropsychiatric lupus is similar to the management of neuropsychiatric disease in patients without lupus. Treatment depends on the underlying causes of a patient’s disease, and may include immunosuppressants, anticoagulants, and symptomatic therapy. [9]

<span class="mw-page-title-main">Lupus nephritis</span> Inflammation of the kidneys

Lupus nephritis is an inflammation of the kidneys caused by systemic lupus erythematosus (SLE), an autoimmune disease. It is a type of glomerulonephritis in which the glomeruli become inflamed. Since it is a result of SLE, this type of glomerulonephritis is said to be secondary, and has a different pattern and outcome from conditions with a primary cause originating in the kidney. The diagnosis of lupus nephritis depends on blood tests, urinalysis, X-rays, ultrasound scans of the kidneys, and a kidney biopsy. On urinalysis, a nephritic picture is found and red blood cell casts, red blood cells and proteinuria is found.

An autoantibody is an antibody produced by the immune system that is directed against one or more of the individual's own proteins. Many autoimmune diseases are associated with such antibodies.

Extractable nuclear antigens (ENAs) are over 100 different soluble cytoplasmic and nuclear antigens. They are known as "extractable" because they can be removed from cell nuclei using saline and represent six main proteins: Ro, La, Sm, RNP, Scl-70, Jo1. Most ENAs are part of spliceosomes or nucleosomes complexes and are a type of small nuclear ribonucleoprotein (snRNPS). The location in the nucleus and association with spliceosomes or nucleosomes results in these ENAs being associated with additional RNA and proteins such as polymerases. This quality of ENAs often makes it difficult to purify and quantify their presence for clinical use.

A systemic disease is one that affects a number of organs and tissues, or affects the body as a whole.

Mixed connective tissue disease, commonly abbreviated as MCTD, is an autoimmune disease characterized by the presence of elevated blood levels of a specific autoantibody, now called anti-U1 ribonucleoprotein (RNP) together with a mix of symptoms of systemic lupus erythematosus (SLE), scleroderma, and polymyositis. The idea behind the "mixed" disease is that this specific autoantibody is also present in other autoimmune diseases such as systemic lupus erythematosus, polymyositis, scleroderma, etc. MCTD was characterized as an individual disease in 1972 by Sharp et al., and the term was introduced by Leroy in 1980.

An autoimmune disease is a condition that results from an anomalous response of the adaptive immune system, wherein it mistakenly targets and attacks healthy, functioning parts of the body as if they were foreign organisms. It is estimated that there are more than 80 recognized autoimmune diseases, with recent scientific evidence suggesting the existence of potentially more than 100 distinct conditions. Nearly any body part can be involved.

They are highly diagnostic of systemic lupus erythematosus (SLE) and are implicated in the pathogenesis of lupus nephritis.

<span class="mw-page-title-main">Lupus</span> Human autoimmune disease

Lupus, technically known as systemic lupus erythematosus (SLE), is an autoimmune disease in which the body's immune system mistakenly attacks healthy tissue in many parts of the body. Symptoms vary among people and may be mild to severe. Common symptoms include painful and swollen joints, fever, chest pain, hair loss, mouth ulcers, swollen lymph nodes, feeling tired, and a red rash which is most commonly on the face. Often there are periods of illness, called flares, and periods of remission during which there are few symptoms.

Lupus headache is a proposed, specific headache disorder in patients with systemic lupus erythematosus (SLE). Research shows that headache is a symptom commonly described by SLE patients —57% in one meta-analysis, ranging in different studies from 33% to 78%; of which migraine 31.7% and tension-type headache 23.5%. The existence of a special lupus headache is contested, although few high-quality studies are available to form definitive conclusions.

The Undifferentiated connective tissue disease (UCTD) is a disease in which the connective tissues are targeted by the immune system. It is a serological and clinical manifestation of an autoimmune disease. When there is proof of an autoimmune disease, it will be diagnosed as UCTD if the disease doesn't answer to any criterion of specific autoimmune disease. Such as systemic lupus erythematosus (SLE), la scleroderma, mixed connective tissue disease, Sjögren syndrome, systemic sclerosis, polymyositis, dermatomyositis, or the rheumatoid arthritis. This is also the case of major rheumatic diseases whose early phase was defined by LeRoy et al. in 1980 as undifferentiated connective tissue disease. The latent Lupus and the incomplete lupus are alternative terms used to describe this condition.

Anti-histone antibodies are autoantibodies that are a subset of the anti-nuclear antibody family, which specifically target histone protein subunits or histone complexes. They were first reported by Henry Kunkel, H.R. Holman, and H.R.G. Dreicher in their studies of cellular causes of lupus erythematosus in 1959–60. Today, anti-histone antibodies are still used as a marker for systemic lupus erythematosus, but are also implicated in other autoimmune diseases like Sjögren syndrome, dermatomyositis, or rheumatoid arthritis. Anti-histone antibodies can be used as a marker for drug-induced lupus.

The congenital heart block (CHB) is the heart block that is diagnosed in fetus or within the first 28 days after birth, some studies also include the diagnosis during early childhood to the definition of CHB. It refers to the disorder in the electrical conduction system within the heart muscle, which leads to the failure in pumping the blood efficiently into the aorta and the pulmonary trunk. The result of CHB can be first, second, or third-degree (complete) atrioventricular block in which no electric signals move from the atrium to the ventricles
