Rheumatoid arthritis risk associates with DNA repair gene XRCC1 Arg399Gln polymorphism in Turkish patients
Rheumatoid arthritis (RA) is an autoinflammatory disease with a genetic background. The synoviocytes in RA shows cellular transformation with tumor-like features, and RA patients have genomic instability and relaxation of DNA repair mechanisms. The polymorphisms in BER repair pathway genes, XRCC1 and OGG1, may change the response to inflammation via altered DNA repair capacity. In this study, we aimed to investigate the relationship between the risk of RA and XRCC1 Arg194Trp, Arg399Gln, and OGG1 Ser326Cys polymorphisms in a group of Turkish RA patients. XRCC1 Arg194Trp, Arg399Gln, and OGG1 Ser326Cys polymorphisms were investigated by PCR-RFLP method in 100 RA patients and 158 healthy control subjects. The results were statistically analyzed by calculating the odds ratios (OR) and their 95% confidence intervals (95% CI) using the chi(2)-tests. RA patients in this study had significantly higher frequencies of XRCC1 Arg399Gln polymorphism in both homozygote (GG) (35%, OR: 7.78 [95% CI: 3.65-16.59], P < 0.001) and heterozygote (AG) forms (41%, OR: 2.17 [95% CI: 1.19-3.96], P < 0.01) and also increased frequency of 399Gln (G) allele (55%, OR:2.99 [95% CI: 1.67-5.37], P < 0.001). We conclude that XRCC1 Arg194Trp, and OGG1 Ser326Cys polymorphisms are not associated with RA; however, Arg399Gln polymorphism is a significant risk factor of RA, and carriers of 399Gln (G) allele have greater risk of RA
Investigation of Poly (ADP-Ribose) Polymerase-1 Genetic Variants as a Possible Risk for Allergic Rhinitis
Recent studies point toward the involvement of poly (ADP-ribose) polymerase-1 (PARP-1) in the pathogenesis of allergic airway inflammation, such as asthma and allergic rhinitis (AR). It has been suggested that inhibition of PARP-1 provides significant protection against systemic or tissue inflammation in animal models. The objective of this study was to investigate whether single-nucleotide polymorphisms of PARP-1 gene are associated with genetic susceptibility to AR. We studied the effect of promoter variations and Val762Ala polymorphism of the PARP-1 gene on the risk for developing AR in a case-control association study with 110 RA patients and 130 control subjects in a Turkish population. The polymorphisms of 410 C/T, -1672G/A, and Val762Ala in the PARP-1 gene were analyzed using the polymerase chain reaction-restriction fragment length polymorphism method. Haplotype analysis of these groups was also performed. The results were statistically analyzed by calculating the odds ratio (OR) and their 95% confidence intervals using chi(2) tests. The heterozygote genotype of the promoter polymorphism (-1672) was significantly found to be associated with susceptibility to AR (OR: 0.56) among the tested single-nucleotide polymorphisms. Haplotypes of PARP-1 -410, -1672, and 762 were not associated with an increased risk for AR. These results raise the possibility that the promoter (-1672) polymorphism of the PARP-1 gene may be a risk factor for AR
Comparison of corneal collagen cross-linking (PACK-CXL) and voriconazole treatments in experimental fungal keratitis
Purpose To compare the antifungal efficacy of corneal collagen
cross-linking with photoactivated riboflavin (PACK-CXL) and voriconazole
in experimental Fusarium solani and Candida albicans keratitis models.
Methods Sixty-four corneas of 32 New Zealand rabbits were included and
divided into two main groups. Intrastromal injection of Fusarium and
Candida suspensions was performed, and it was observed that keratitis
was formed on the third day. Both groups were randomly separated into
the following four groups: control, PACK-CXL, voriconazole and PACK-CXL
combined with voriconazole. PACK-CXL was applied using 0.25\% riboflavin
in an accelerated Dresden protocol (total ultraviolet A dose 5.4
J/cm(2)). Voriconazole was applied topically as 7x1/day with a dose of
1\% (10 mg/ml). Corneal buttons were excised on the tenth day, and
microbiological and pathological examinations were performed. Results
The PACK-CXL and PACK-CXL combined with voriconazole groups each had 100
colony-forming unit (CFU/ml) of reproduced micro-organisms compared with
500 CFU/ml in the voriconazole group and 1500 CFU/ml in the control
group (p < 0.001) in the Fusarium keratitis model. The PACK-CXL combined
with voriconazole group had 100 CFU/ml, the PACK-CXL group had 150
CFU/ml, and the voriconazole group had 200 CFU/ml of reproduced
micro-organisms compared with 4000 CFU/ml in the control group (p <
0.002) in the Candida keratitis model. (p < 0.001). Fewer hyphae and
non-specific stromal changes were observed in the pathological cross
sections examined in subgroups that used CXL. Conclusion There was less
fungus reproduction and a lower keratitis score for Fusarium solani and
Candida albicans in the treatment groups compared to the control groups,
especially in groups that used PACK-CXL. These results suggest that it
is useful to combine PACK-CXL treatment with medical treatment in the
fungal keratitis algorithm at the early stage of the disease
One-Year Follow-Up Results of MIS-C Patients with Coronary Artery Involvement: A Multi-center Study
Multisystem inflammatory syndrome (MIS-C) in children is a rare complication of SARS-CoV-2 infection. Knowing the course of the affected or unaffected coronary arteries in the patients under follow-up is important in terms of defining the long-term prognosis of the disease and determining the follow-up plan. This is a multicenter and retrospective study. The data were obtained from nine different centers. Between May 2020 and August 2022, 68 of 790 patients had coronary artery involvement. One-year echocardiographic data of 67 of 789 MIS-C patients with coronary artery involvement were analyzed. Existing pathologies of the coronary arteries were grouped as increased echogenicity, dilatation and aneurysm according to Z scores, and their changes over a 1-year period were determined. The data of all three groups are defined as frequency. SPSS Statistics version 22 was used to evaluate the data. In our study, aneurysm was observed in 16.4%, dilatation in 68.7% and increased echogenicity in 13.4% of the patients. All of the patients with involvement in the form of increased echogenicity recovered without sequelae by the end of the first month. No progression to aneurysm was observed in any of the patients with dilatation. No new-onset involvement was observed in patients with previously healthy coronary arteries during the convalescent period. In addition, from the sixth month follow-up period, there was no worsening in the amount of dilatation in any of the patients. At least 94% of the patients who completed the 12th month control period returned to normal
