- Objectives: To systematically assess the magnitude of suicidal behavior among PsA patients and identify associated risk factors. Also identify common genes or coinherited single nucleotide polymorphisms (SNPs) implicated in suicidal behavior and PsA.Methods: Based on the PRISMA guidelines, we conducted a systematic literature review of the online databases PubMed/Medline, Web of Science, and EMBASE from inception to May 2022. Full-text original articles that describe suicidal behavior in PsA patients were eligible. All registered genome-wide association study (GWAS) data in the GWAS catalog database for PsA and psychiatric traits, such as suicidal behavior, and depression, were downloaded for further analysis.Results: A total of 48 articles were identified, and 6 were relevant to the study question. Among the 122,160 PsA patients, 700 had suicidal behavior (0,57%). The range of age in one study was between 30 and 49 years, and 64% of PsA patients with suicidal behavior were female. Among 13,899 PsA patients 74 had suicidal ideation (0.53%) and 125 suicide attempts occurred (0.9%). In two studies, among 17,383 patients, 13 complete suicides occurred (0.07%). A genetic haplotype on chromosomal region 6p21.1, spanning from 29,597,596 to 32,251,264 Mb, contains predisposing SNPs for PsA and depression. 6p21.1–6p21.3 is the chromosomal region containing the HLA genes of classes I, II and III.Conclusion: Suicide behavior in PsA patients was associated with depression and other psychiatric comorbidities. Further evidence supports a genetic origin, at least partly. Awareness of these findings can help clinicians to recognize suicide behavior and prevent suicide attempts.

- Background: Previous studies suggested that patients with Systematic Lupus Erythematosus (SLE) have a higher risk of suicidal behavior, including suicidal ideation, attempt and complete suicide. Systematic data describing the SLE patients’ clinical characteristics and risk factors of suicidal behavior are lacking.Objectives: To determine the magnitude of suicidal behavior among SLE patients and to examine predictors associated with suicidal behavior. An additional aim was to identify common genes or coinherited single nucleotide polymorphisms (SNP) implicated in suicidal behavior and SLE.Methods: We conducted a systematic literature review based on PRISMA guidelines using the online databases PubMed/Medline, EMBASE and Web of Science, from inception to August 2021. Full-text original articles that examined the relationship between SLE patients with suicidal behavior were eligible for our review. Two reviewers independently reviewed articles to assess eligibility using the Newcastle-Ottawa Scale and the Joanna Briggs Institute criteria. Systematic reviews, metanalysis, narrative review, case reports, case series, including less than 10 patients, and conference abstracts, were excluded. All registered genome-wide association study (GWAS) data in the GWAS catalog database for SLE and psychiatric traits (suicidal behavior, depression, anxiety, psychosis) were downloaded for further analysis. Special in silico tools were used to examine if any genetic polymorphisms (SNPs) that predispose for SLE or psychiatric traits can be inherited together as a single haplotype. This could be posing a risk factor for a coexisting psychiatric condition in SLE patients.Results: Of the 64 articles identified, 22 were relevant to the study question; cross-sectional (n = 8) and prospective cohorts (n = 6) were the most frequently retrieved studies. Among the 27,106 SLE patients with SLE, 802 had suicidal behavior (2.9%), and of those, 87.9% were female. Suicide attempt occurred in 573/802 (71.4%) and complete suicide in 18/802 (3%). Major depressive disorder was the most frequently reported coexisting psychiatric condition associated with suicidal behavior, followed by psychosis and social phobia. In addition, several clinical manifestations were linked to suicidal behavior, particularly neuropsychiatric lupus, serositis, mucocutaneous, and renal involvement. Further, high scores in disease activity and damage indices were associated with suicidal behavior. A haplotype in chromosomal region 6p21.33 was found to contain a combination of risk alleles predisposing for SLE and depression, the most common psychiatric disorder associated with suicidal behavior.Conclusion: Suicide behavior in SLE patients was associated with depression, neuropsychiatric lupus, active disease and damage. Further evidence supports a genetic origin of psychiatric symptoms in SLE patients. Awareness of these findings can guide clinicians to recognize suicide behavior promptly and prevent suicide attempts.

- Background: Several studies have shown that autoimmune diseases are associated with psychiatric diseases like depression and psychosis. Genetic evidence supports this association. The aim of this study was to investigate if genetic variants predisposing to autoimmune diseases and psychiatric disorders are genetically linked, constructing the common haplotypes.Methods: All registered single nucleotide polymorphisms (SNPs) in the Genome-wide association studies (“GWAS catalog”) having been associated with autoimmune rheumatic and endocrine diseases were investigated for being in linkage disequilibrium with any psychiatric disorders’ associated SNPs. Analysis was performed by the LDtrait and LDhap bioinformatics tools.Results: Multiple chromosomal regions have been detected containing rheumatic/endocrine diseases’ predisposing SNPs and psychiatric disorders’ predisposing SNPs. The genetic haplotypes have been constructed for some of these genetic regions. Six of the autoimmune rheumatic and endocrine diseases examined here share a common haplotype with psychiatric diseases at the HLA locus 6p21-22.Conclusion: Our study shows that autoimmune diseases and psychiatric diseases are genetically linked. Genetic haplotypes have been constructed, showing in detail this genetic linkage.

- Inuit is the population with the highest incidence of suicide attempt and cancer in the world. Previous studies reported that people attempted suicide have a higher future risk for cancer. In view of these data, the largest available genome wide association studies (GWAS) for four major mental disorder groups were screened here for any common genes with all known cancer associated genes and oncogenes/tumor suppressor genes. A common genetic background came out only between suicide attempt and cancer (cancer associated genes analysis: RR = 1.64, p = 7.83 × 10−5; oncogenes/tumor suppressor genes analysis: RR = 2.55, p = 2.82 × 10−22), this supporting existing epidemiological data. Incidence/prevalence of both conditions was found to correlate with extreme cold geographical regions (adjusted R2 = 0.135, p = 3.00 × 10−4); this is not the case for other mental disorders. Our results show a possible genetic link between suicide attempt and cancer and a possible evolutionary connection of both diseases with extreme cold environments. These data are useful for future molecular studies or even for investigation of possible therapeutic protocols.
