Presentation
LRBA deficiency presents as a syndrome of autoimmunity, lymphoproliferation, and humoral immune deficiency. [en.wikipedia.org]
A fraction of early-onset IBDs presenting with more severe disease course and incomplete response to conventional treatment is assumed to be inherited in a Mendelian fashion, as exemplified by the recent discovery of interleukin (IL)-10 (receptor) deficiency [pubfacts.com]

The patient presented at the age of 3 months with severe protracted diarrhea, hypoproteinemia and anemia. [ojrd.biomedcentral.com]
In 2 siblings from a consanguineous family presenting with early onset polyautoimmunity, we presumed autosomal recessive inheritance and performed whole exome sequencing. [unboundmedicine.com]

Recurrent Infection
Before the discovery of these gene mutations, patients were diagnosed with common variable immune deficiency (CVID), which is characterized by low antibody levels and recurrent infections. [en.wikipedia.org]
Invasive recurrent infections sustained by Neisseria species are an indication for assessing complement levels and function. [accessmedicine.mhmedical.com]
Immune dysregulation (95%), organomegaly (86%), recurrent infections (71%), and hypogammaglobulinemia (57%) were the main clinical complications observed in LRBA-deficient patients. [frontiersin.org]
Affected individuals have early-childhood onset of recurrent infections, particularly respiratory infections, and also develop variable autoimmune disorders, including idiopathic thrombocytopenic purpura, autoimmune hemolytic anemia, and inflammatory [genecards.org]

Plethora
To our knowledge, more than 60 patients with LRBA deficiency have been reported, with a plethora of diverse mutations identified and with highly variable clinical and immunologic characteristics [ 1 – 18 ]. [ojrd.biomedcentral.com]

Pseudotumor
Several neoplasms are reported in LRBA deficiency: Burkitt lymphoma [ 10 ], low-grade Ebstein Barr virus positive (EBV ) marginal zone lymphoma [ 17 ], lymphomatous central nervous system pseudotumor [ 2 ], dysplastic tubular adenoma and polyps [ 18 ] [ojrd.biomedcentral.com]

Legionella Pneumophila
Patient 1 also developed Legionella pneumophila pneumonia, and patient 2 developed psoriasis. [doi.org]
The patient suffered from several opportunistic infections, including Campylobacter jejuni, Morganella morganii, Proteus mirabilis, Yersinia enterocolitica, Cryptospordium parvus, Giardia lamblia, Legionella pneumophila, pulmonary aspergillosis and aspergilloma [ojrd.biomedcentral.com]

Helicobacter Pylori
Immunohistochemical studies for Helicobacter pylori were negative. Further treatment with chemo- and radiotherapy was suggested, which the patient declined. [ojrd.biomedcentral.com]

Lymphocytic Infiltrate
C TLA4 gene h aploinsufficiency with a utoimmune i nfiltration (CHAI) leads to broad clinical manifestations such as hypogammaglobulinemia, enteropathy, recurrent infections, lymphocytic infiltration, and multiple autoimmune clinical features, very similar [ojrd.biomedcentral.com]
Treatment
Lymphocytic interstitial lung disease (ILD) causes substantial morbidity and mortality in CVID, and there is no effective treatment ( 3 – 6 ). [doi.org]
Larger cohorts are required to further validate these therapeutic approaches as effective long-term treatments for this disorder. [en.wikipedia.org]

Prognosis
Diagnosing monogenic autoimmunity is crucial for patients’ prognosis and clinical management. [diabetes.diabetesjournals.org]
The role of LRBA gene knockout in cancer development and its prognosis remains to be elucidated. [ojrd.biomedcentral.com]
Etiology
They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]

A panel of candidate genes used for the analysis of VEO-IBD can allow a timing diagnosis and an effective cure in many patients, as well as an epidemiologic definition of the real impact of PIDs in this field. [wjgnet.com]
Pathophysiology
However our observations in the clinic show that only a fraction of patients respond to conventional therapies that are based on these models, underlining the need to understand the pathophysiologic mechanisms specifically in humans in better detail. [cemm.at]
Prevention
The Research tab has information about how NIAID conducts and supports research to understand, treat, and ultimately prevent disease, as well as useful resources and tools specifically for researchers. [niaid.nih.gov]
In LRBA-deficient cells, inhibition of lysosome degradation with chloroquine prevented CTLA4 loss. [doi.org]
It will adopt appropriate prevention and intervention measures based on the test results, so that to provide the scientific level clinicians effective individual treatment plan and predict cancer risk. [mygenostics.com]
Several mechanisms have been identified that are important for the normal regulation of the cryopyrin inflammasome in order to prevent uncontrolled inflammation... [readbyqxmd.com]
CTLA4 serves as a critical checkpoint inhibitor as it downregulates T cell activation to prevent autoimmunity and allow tolerance to self-antigens. Wang JW et al. showed that LRBA is significantly upregulated in multiple tumor types [ 41 ]. [ojrd.biomedcentral.com]
