Abstract

Lupus is an autoimmune illness that affects the skin, kidneys, lungs, heart, and brain. The lack of tolerance to selfantigens and the production of autoantibodies are two of the autoimmune disorders that cause Systemic Lupus Erythematous (SLE). SLE frequently results in the formation of immunological complexes, which trigger leukocyte activation and the generation of cytokines, all of which contribute to systemic inflammation and tissue damage. Lupus patients often develop neuropsychiatric symptoms that lead to Neuropsychiatric Lupus (NPSLE) or Central Nervous System Lupus (CNS). These symptoms, which include cognitive impairment, mood problems, seizures, headaches, and psychosis, are among the most common manifestations of the illness, affecting up to 80%of adults and 95% of children with lupus.

Description

There are specific group of antibodies that are responsible for the neuropsychiatric symptoms of lupus. Brain cytoplasmic RNA’s are fragments of genetic information that neurons utilize to control the production of proteins. They have parts that code for where the proteins should be carried in the neuron, known as the synapse. This sort of RNA is suspected to be the target of an immunological response gone wrong in lupus, although the exact mechanism is unclear. The researchers discovered antibodies target regulating brain cytoplasmic RNA’s which are specific to lupus patients. These antibodies control the protein synthesis regulators that allow synapses in the brain to control how they receive, store, and recall information. These antibodies are unique in the brains of lupus patients and can be a foundation of neuropsychiatric symptoms that these people experience. Researchers provided a set of classifications for 19 NPSLE syndromes, which were then classified as either CNS or Peripheral Nervous System (PNS) manifestations of this disease.

The following CNS syndromes have been seen in NPSLE:

• Aseptic meningitis

• Cerebrovascular disease

• Demyelinating syndrome

• Headaches, migraines, and intracranial hypertension

• Movement disorders

• Myelopathy

• Seizures

• Acute confusional state

• Anxiety disorders

• Cognitive dysfunction

• Mood disorders

• Psychosis

In comparison to the 12 CNS syndromes that constitute NPSLE, the PNS is affected by a total of seven syndromes, including:

• Guillain-Barre syndrome

• Autonomic disorder

• Simple or multiple mononeuritis

• Myasthenia gravis

• Cranial neuropathy

• Plexopathy

• Polyneuropathy

Several theories have been proposed to explain NPSLE; however, the extremely complex cascade of pathophysiological events that occur in lupus has limited our understanding of why NPSLE occurs. Many rheumatologists believe that the presence of autoantibodies in the serum and Cerebrospinal Fluid (CSF) might cause SLE-related neurological symptoms. So far, twenty lupus autoantibodies, including Anti-Nuclear Antibodies (ANAs), Anti-N-methyl-D-aspartate receptor (anti-NMDA) antibodies, Anti-Phospholipid Syndrome antibodies (APS), and others, have been discovered as potential NPSLE contributors. Each of the autoantibodies linked to NPSLE has its possible mechanism for generating neuropsychiatric symptoms in lupus patients. APS antibodies, for example, attach to endothelial cells via disrupting the coagulation cascade, resulting in a procoagulant state. As a result, brain vascular thrombosis and ischemia can ensue, leading to the clinical presentation of NPSLE. Because cerebrovascular illnesses are among the most prevalent indications of NPSLE, these ischemic strokes are almost certainly caused by APS. In comparison, some forms of lupus autoantibodies linked in NPSLE are likely to cross a defective Blood-Brain Barrier (BBB). Anti-ribosomal-P or anti- NMDA antibodies are the most prevalent autoantibodies linked with this autoimmune inflammatory mechanism of NPSLE; nevertheless, anti-endothelial and anti-neural antibodies are discovered. Inside the brain parenchyma, these antibodies can cause neuronal death by increasing the production of proinflammatory cytokines. Increased cytokine production from the PNS or CNS has been identified as a potential mediator in NPSLE. Interleukin IL-1, IL-6, Interferon-Alpha (IFN), and Tumor Necrosis Factor-Alpha (TNF) are some of the cytokines that disrupt the Blood-brain barrier in NPSLE. Many autoantibodies that have crossed the BBB are thought to bind to auto-antigens and initiate cytokine signaling cascades, which then activate the transcription and production of both cytokines and chemokine’s. Although research has been conducted to establish this mechanism of NPSLE, more molecular investigations are needed to corroborate this mode of action for both cytokines and chemokine’s in the pathogenesis of NPSLE. Despite the fact that NPSLE affects between 37 percent and 95 percent of lupus patients, it remains one of the most difficult features of the disease. One of the most challenging components of NPSLE epidemiology is determining whether a patient's neuropsychiatric symptoms are directly related or not to their lupus disease. Several lupus medications, such as glucocorticoids, as well as the presence of comorbidities, such as hypertension or hyperlipidemia, these conditions might cause neuropsychiatric symptoms that are unrelated to the illness. To determine whether the neuropsychiatric symptoms of NPSLE are linked to the lupus sickness or not, a unique ACR technique for the diagnosis of NPSLE has been devised. Although NPSLE can develop at any time during lupus, there have been several reports of NPSLE patients presenting with symptoms both at the time of their lupus diagnosis and before the onset of systemic lupus signs. Indeed, depression-like symptoms have been detected as early as five weeks of life in the MRL mouse model of lupus, which is equal to 16 weeks of age, when renal damage and autoantibody production are prevalent in this mouse model. These findings support the concept that NPSLE is caused primarily by neurological factors rather than systemic inflammation or medication-related side effects.

Treatment for NPSLE may involve therapy focused on an underlying cause, such as autoantibody-mediated damage or a hyper-coagulable disease, as well as anti-epileptic, anti-depressive,anti-neuropathy, and other medications to control symptoms. There are presently no randomized controlled studies to validate specific NPSLE medication or regimens. As a result, therapy plans are based on professional advice, case studies, and small controlled trials. NPSLE therapy should be unique to the patient's specific needs, including suspected mechanisms such as the presence of specific antibodies or evidence of thrombosis, the severity of symptoms, expected morbidity, time from onset of symptoms, reversibility, response to prior therapies, and effect on the quality of life. Depression, migraines, and repeated seizures, for example, are not frequently linked with SLE disease, but rather related disorders or a reaction to a past incident (for example, post-stroke seizures). In contrast, if a new disease is found, especially in the context of high SLE activity, immunosuppressive treatment is essential to regulate the autoimmune process and avert additional damage.

Conclusion

Over the last several decades, enormous efforts have been made to clarify the pathogenesis of NPSLE as well as to enhance its categorization, diagnosis, and therapy. This acquired knowledge has improved our comprehension and capacity to assist patients. However, some major questions remain unresolved, including whether diffuse, mild, and non-specific symptoms (such as headaches) should be regarded as the same disease as more established signs of NPSLE. Because the same etiologies are unlikely to be responsible for all NPSLE patients, improved subgrouping is necessary for clinical and research purposes. The function of novel imaging modalities (such as MRS and SPECT, for example) in the diagnosis and follow-up of NPSLE should be specified. New biomarkers should be discovered. Many researchers propose creating a severity NPSLE score based on symptoms, imaging, and laboratory data. This score will be used to advice treatment intensity and to aid in the monitoring of clinical investigations. Future research on these pressing issues is required, particularly in the current era of biology, target therapeutics, and customized medicine.
