Type 1 is transmitted through non-sexual contact through childhood, while type 2 is usually transmitted through sexual contact during adulthood. Cytomegalovirus shares many characteristics with other herpes viruses, it is a prevalent opportunistic infection in human immunodeficiency virus (HIV) infected patients and is a major cause of viral complications among organ donation recipients.ObjectivesThe purpose of this study was to investigate the frequency of immunoglobulin antibodies for HSV-1, HSV-2, and CMV viruses among latency and reactivation cases using ELISA technique.MethodologyA cross-sectional investigation was performed among 147 (58 males, 89 females) aged 18-60 years who visited AL-Numan Teaching Hospital for routine check-ups from September 2023 to April 2024. Blood samples ( 5 ml) were collected and serum was separated for antibody testing using commercial ELISA kits. <b>Inclusion cases</b> included; adult's patients aged 18-60 years with no active symptoms of viral infection. <b>Exclusion cases</b> included immunocompromised patients and those receiving antiviral therapy. Sample size was computed based on the estimated geographical incidence rates with 95% confidence interval and 5% margin of error.ResultsHSV-1 had an alarming 65.3% seroprevalence, with 14.3% exhibiting recent infection/reactivation (IgM+). HSV-2 afflicted 22.4%, with a significant female preponderance (73.5%) and a strong connection with marital status (r = 0.605, <i>p</i> < 0.001). CMV seroprevalence has reached 24.4%. Age, marriage, and smoking were identified as significant risk factors, particularly for sexually transmitted HSV-2.ConclusionThis study demonstrates an extremely high herpesvirus load in Baghdad: two-thirds had HSV-1, while one-quarter have HSV-2 or CMV. The epidemic-level prevalence of HSV-1 necessitates prompt public health intervention. Strong demographic relationships, particularly the HSV-2 marital correlation, give actionable intervention targets. These findings establish Iraq's first complete herpesvirus baseline, highlighting the critical need for national surveillance infrastructure and tailored prevention initiatives to tackle this significant infectious disease burden.</p>","PeriodicalId":53564,"journal":{"name":"Human Antibodies","volume":" ","pages":"10932607251355483"},"PeriodicalIF":0.0,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144531037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We determined the levels of IL-5 and IL-9 using the enzyme-linked immunosorbent assay (ELISA) after separating sera from peripheral blood. Additionally, the allele-specific PCR method was used to identify the polymorphism distribution of rs2069812 (IL-5) and rs1859430 (IL-9).ResultsStudy participants with allergic asthma had significantly higher levels of interleukin (IL)-9 and interleukin (IL)-5 than those in the healthy subjects: 2 and 2.39 ± 0.18 pg/ml, compared to 1.004 ± 0.04 pg/ml and 2.21 ± 0.16 pg/ml, respectively, with a significance level of P < 0.05. In terms of age, gender, and place of residence, there was no statistically significant difference between the ill group and the healthy control group. The patients' group had 66 cases of the heterozygous genotype TG compared to 58 cases in the control group. Thus, the TG genotype was associated with an increased risk of allergic asthma illness (etiologic fraction: 0.2963) and an odds ratio of 2.4074 (95% CI: 1.2462-4.6505). The patients' group also had a higher frequency of the homozygous genotype GG (65 cases vs. 54 cases in the control group). The odds ratio for allergic asthma illness was 1.0578 (95% CI: 0.6386-1.7522), and the etiologic fraction was 0.0299, indicating that genotype GG was a risk factor.ConclusionsThese findings provide more evidence that interleukin-5 and interleukin-9 play critical roles in allergic asthma, particularly in eosinophilic inflammation. Consequently, it is important to target them in order to reduce asthma allergy and improve asthma treatment. It is clear that IL-5 and IL-9 levels directly influence allergic asthma in patients compared with healthy individuals.</p>","PeriodicalId":53564,"journal":{"name":"Human Antibodies","volume":" ","pages":"10932607251349046"},"PeriodicalIF":0.0,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144259405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The diagnosis was designed by the consultant medical staff at the clinic. Eligible individuals had a positive nasal swab for reverse transcription polymerase chain reaction for severe acute respiratory syndrome coronavirus 2 infection. They were compared with 50 healthy individuals as a control group. Every participant's anthropometric and clinical features were measured. The study includes the study groups' glycemic, lipid profile, serum urea, and C-reactive protein (CRP) measurements.ResultsThere were remarkable rises (<i>p </i>< 0.05) in fasting and random blood glucose, serum lipid, and urea levels in diabetic patients with COVID-19 compared to those without COVID-19 and the control group.
