Allergic asthma is a type of asthma that provokes symptoms when an individual is exposed to certain triggers, such as pollen, animal sources of allergens, and other various types of allergens. These allergens cause an immune response that influences lungs and leads to difficulties in breathing. The current study is performed to estimate the concentrations of immunoglobulin E (IgE) and interleukin-13 (IL-13), tested by using the enzyme-linked immunosorbent assay (ELISA) and the numbers of eosinophils, calculated by using hematological analyzers, in the blood of patients with allergic asthma. A total of 150 patients and 50 healthy individuals were randomly selected for the study. The results revealed that IgE and IL-13 levels as well as eosinophil percentage were significantly increased (p<0.001) in the patients in comparison to the healthy individuals. These parameters deem to be a key element in allergic asthma pathogenesis. They also help in the diagnosis and management of the disease.
The aim of this study was to investigate the correlation between GRIN2A rs387906637 polymorphism and susceptibility to epilepsy. Blood samples were collected from 85 volunteers, dividing into 60 epilepsy patients (34 males and 26 females) and 25 healthy subjects (19 males and 6 females).The DNA was extracted and GRIN2A rs387906637 polymorphism was analyzed by Real-time PCR using two probes and primers. The results showed no significant differences between patients and control samples; therefore, there are no allelic and genotypic correlations of this SNP with epilepsy. This study indicated that GRIN2A rs387906637 polymorphism is not a risk factor for epilepsy in the studied set of patients.
Systemic Lupus Erythematosus (SLE) is a multifactorial chronic systemic autoimmune disease. It is characterized by a lack of immune tolerance to autoantigens such as nuclear antigens. The aim of the study is to assess the interferon-alpha (IFN-α) serum level in Iraqi patients with SLE and determine its potential relation to different clinical and laboratory parameters and disease activity. 100 SLE patients were all females and with a mean of age 31.3 ± 10 years (16-63years) and disease duration of 5.8 ± 3.7years (1 month to 15 years). The average of SLEDAI score ranged from 2 to 22 with a mean of (8.53 ±3.42). Proteinuria, ESR, creatinine and AST were significantly higher (65% vs. 10% and 0.62±0.11 vs. 0.70±0.14 mg/dl respectively) while the PLT was significantly lower (231.9±88.8 vs. 282.3±67.3 103/mL) (p< 0.001) among SLE patients as compared to control. Serum levels of IFN-α were increased in the SLE patients compared to control, and no significant difference has been observed (208.7±530.0 vs. 63.7±34.8 pg/ml) respectively (P=0.245). Interferon-alpha showed a significant negative correlation with the SLE Disease Activity Index (SLEDAI) in the active and inactive groups. There were no significant variations in all study parameters across IFN-α serum levels (p greater than 0.05). In conclusion, the results suggest a risk effect for female gender and age in etiology of SLE. IFN-α could not be considered as biomarker or to have a risk effect in SLE patients or perpetuate the disease activity. No evidence for any correlation between the IFN-α serum level and any clinical manifestations or laboratory investigation of the disease in current study except for age and disease duration, which suggests them as a risk factor for increasing the IFN-α serum level.
Systemic lupus erythematosus (SLE) is a multifactorial chronic autoimmune disease, with a wide spectrum of effect. The main feature of the disease is the production of a wide variety of autoantibodies as a result of immune tolerance loss. The work aims to evaluate the miRNA-146a gene polymorphism potential association with disease activity and chronicity changes in SLE patients. The study included 100 SLE patients and 50 matched controls. The systemic lupus erythematosus disease activity index (SLEDAI) was assessed. The single nucleotide polymorphism (SNP) of miR-146a gene (rs2910164) polymorphism was assayed by polymerase chain reaction (PCR) and sequencing technique in patients and control. 100 SLE patients were all females and with a mean of age 31.3 ± 10 years (16-63years) and disease duration of 5.8 ± 3.7years (1 month to 15 years). Most clinical manifestations presented in patients were 52% malar rash, 45% oral ulcers, 54% arthritis, and 45% neurological disorder. Proteinuria, ESR, creatinine and AST were significantly higher (65% vs. 10%, 4.1±36.1 vs. 11.8±9.9 mm/hr, 0.62±0.11 vs. 0.70±0.14 mg/dl and 25.37±26.50 vs. 17.23±3.58 U/L respectively) while the PLT was significantly lower (231.9±88.8 vs. 282.3±67.3 103/mL) (p< 0.001) among SLE patients as compared to control. There were no significant variations in all study parameters across miRNA-146a genotypes (p greater than 0.05). There was a significant association of the homozygote GG genotype (66.7%) with the active SLE state (p=0.013). In conclusion, the results suggest a risk effect for the female gender and adult at a young age in the etiology of SLE. The miRNA-146a GG genotype is associated with increasing the disease activity and miRNA-146a polymorphism is not associated with the risk in SLE.
