LADA versus classic adult-onset type 1 diabetes was independently related to sTNFRII (odds ratio [OR] 1.9 [95% CI 1.01-3.97]; <i>P</i> = 0.047) and hs-CRP levels (OR 0.78 [95% CI 0.62-0.96]; <i>P</i> = 0.019), and a higher number of total leukocytes lowered the risk of LADA compared with type 2 diabetes (OR 0.98 [95% CI 0.97-0.99]; <i>P</i> = 0.036).
LADA showed a close relationship with genetic polymorphisms of HLA-DQB1 and WHLA-DRB1, which could contribute to a better understanding of disease pathogenesis and the identification of predisposing loci in the diagnosis and treatment of LADA.
A significantly elevated positivity for MAP/proinsulin was detected among patients, with the highest prevalence in the 32-41-year-old T1D-like LADA subgroup, supporting our hypothesis of a possible MAP contribution in the development of autoimmunity.
Additionally, there was an increased association between LADA and CTLA-4 diabetes-susceptibility genotypes and decreased association with INS VNTR and high-risk HLA-DQB1 alleles, compared with T1D.

Although patients with LADA had an increased frequency of HLA-DQB1 and PTPN22 risk genotypes and alleles compared with type 2 diabetic subjects, the frequency was significantly lower compared with T1D(>35y) patients.

Associations of HLA-DR3/DQ2 with GAD65 and DR4 with IA-2 antibodies in insulin-dependent diabetes mellitus (IDDM) and DR3/DQ2 with GAD65 antibodies in latent autoimmune diabetes in adult (LADA) patients are known.
Between SPIDDM and LADA some differences are reported in terms of some genetic predispositions including HLA class II and class I genes, vitamin D receptor gene, and CTLA4 genes.

Both type 1 diabetes mellitus and LADA were positively associated with the DRB1*04-DQB1*0302 (DR4/DQ8) haplotype (P=0.00001, and P=0.0005, respectively), and negatively associated with the DRB1*11-DQB1*0301 (DR11/DQ7) haplotype (P=0.00006, and P=0.007, respectively) compared with control population.

Compared to healthy controls, the expression of histone acetyltransferases CREBBP in LADA patients was downregulated, and the expression of histone deacetylases HDAC1 and HDAC7 was upregulated.Conclusion.
