Systemic lupus erythematosus (SLE) is a prototypic systemic autoimmune disease. Adiponectin is an adipocyte-derived cytokine with anti-inflammatory, antidiabetic, and antiatherogenic properties. No study has reported on the association between adiponectin (ADIPOQ) gene and SLE. Our aim is to investigate the association between single-nucleotide polymorphisms in ADIPOQ gene and SLE. We examined 179 SLE patients and 237 age- and gender-matched controls from Sichuan province in China. Genotypes were determined using polymerase chain reaction-restriction fragment length polymorphism and DNA sequencing. Results show that there was no significant difference in the allele frequencies of rs1501299 (P=.311,OR=1.17, 95% CI: 0.86–1.59) and rs2241766 (P=.929,OR=0.99, 95% CI: 0.74–1.33) in ADIPOQ gene between SLE patients and controls. The same results were seen in their genotypes (P<.05). The allele frequencies of rs1501299 and rs2241766 polymorphisms of ADIPOQ may not be associated with SLE risk.

Objectives. This study was to investigate the association of melatonin (MTN) pathway gene’s single-nucleotide polymorphisms (SNPs) with susceptibility to systemic lupus erythematosus (SLE). Methods. We recruited 495 SLE patients and 493 healthy controls, 11 tag SNPs in MTN receptor 1a (MTNR1a), MTNR1b, and arylalkylamine N-acetyltransferase (AANAT) genes were genotyped and analyzed. Serum MTN concentration was determined by enzyme-linked immunosorbent assay (ELISA) kits. Results. Two SNPs of AANAT gene (rs8150 and rs3760138) associated with the risk of SLE; CC carriers of rs8150 had a lower risk as compared to GG (OR=0.537, 95% CI: 0.361, 0.799), whereas GG carrier in rs3760138 had an increased risk (OR=1.823, 95% CI: 1.154, 2.880) compared to TT. However, we did not find any genetic association between the other nine SNPs with SLE risk. Case-only analysis showed associations of rs2165667 and rs1562444 with arthritis, rs10830962 with malar rash, rs3760138 with immunological abnormality, and rs8150 with hematological abnormality. Furthermore, a significant difference between plasma MTN levels with different genotypes of rs1562444 was observed. Haplotype analyses revealed that haplotype of CCTAT, CTAGT, and GGG was significantly associated with the increased risk in SLE susceptibility, but TCTAT and CTG appeared to be a protective haplotype. Conclusions. The present study supported the genetic association of MTN pathway genes with SLE susceptibility and specific clinical manifestations, suggesting the potential role of MTN pathway genes in the pathogenesis and development of SLE.

Hydroxychloroquine (HCQ) has been used to treat systemic lupus erythematosus (SLE) in Japan since 2015. We herein report a case of SLE that developed generalized pustular psoriasis (GPP) following the administration of HCQ. Twenty-one days after the HCQ treatment, a pustular rash with itching appeared on the auricle, scalp, and forearm, and spread rapidly to the face and body trunk with a high fever and arthralgia. Skin biopsy showed pustule formation under the cornified layer, neutrophil infiltration, the destruction of keratinocytes, and spongiform pustules of Kogoj. The patient was diagnosed with GPP. HCQ was immediately discontinued, the dose of prednisolone (PSL) was increased, and granulocyte and monocyte adsorption apheresis was performed. Her symptoms subsequently disappeared. Since arthralgia relapsed after the tapering of PSL, cyclosporine was added. Although single nucleotide polymorphisms (c.28C>T and c.115+6T>C) in the interleukin (IL)-36RN gene, which encodes the IL-36 receptor antagonist, have frequently been reported in GPP, these mutations were not observed in the present case. The potential development of GPP needs to be considered when administering HCQ to patients with SLE.

Objective.To investigate the association of the functional FCRL3 single-nucleotide polymorphism (SNP) −169T/C with disease phenotypes and susceptibility to systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) in Taiwanese.Methods.FCRL3 SNP −169T/C was genotyped in 573 patients with SLE, 670 patients with RA, and 758 controls. Genotype distributions and allele frequencies were compared among the 3 groups as aggregates or as stratified by clinical characteristics, autoantibody profile, and sex within patient groups.Results.Overall, FCRL3 SNP −169T/C was not associated with susceptibility to either SLE or RA. However, −169CC genotype was significantly reduced in leukopenia-positive SLE patients as compared to the leukopenia-negative SLE patients (CC vs CT+TT, p = 6 × 10−4, OR 0.444, 95% CI 0.279–0.708) and controls (p = 6.1 × 10−3, OR 0.583, 95% CI 0.396–0.857). On the other hand, −169TT genotypes were significantly more numerous in RA patients with non-destructive disease as compared with patients with destructive disease (CC+CT vs TT: p = 0.007, OR 1.672, 95% CI 1.149–2.432). The −169T allele frequency was also significantly increased in non-destructive RA compared with patients with destructive disease (C vs T: p = 0.010, OR 1.423, 95% CI 1.089–1.859). FCRL3 SNP −169TT homozygous donors were significantly more numerous among female cyclic citrullinated peptide (CCP)-negative RA patients versus female CCP-positive RA patients (CC+CT vs TT: p = 0.019, OR 1.64, 95% CI 1.085–2.479).Conclusion.The functional FCRL3 SNP −169T/C appears to play important roles in the development of certain phenotypes such as SLE leukopenia and RA disease severity in Taiwanese patients with SLE and RA.
