Seminal plasma hypersensitivity: A systematic review of clinical presentation, diagnostics, and management options.

INTRODUCTION: Seminal plasma hypersensitivity (SPH) is a rare and often misdiagnosed condition characterized by local and/or systemic reactions to seminal plasma proteins following exposure to semen. We aimed to summarize key symptomatology, diagnostic features, and management options for SPH. METHODS: The databases PubMed, EMBASE, Web of Science, Google Scholar, and Cochrane Review were searched with key words "seminal plasma hypersensitivity" and "seminal fluid allergy" through September 2023. Exclusion criteria included non-English articles, in vitro studies, publication before 1990, duplicates, and articles with no clinical relevance to SPH in women. RESULTS: The search yielded 53 articles for review. Of these, 60.5% described systemic SPH and 39.5% described localized. CONCLUSION: Diagnosis of SPH relies on a thorough patient history and confirmatory skin prick testing. The use of IgE assays is controversial and less accurate for cases of localized SPH. Knowledge of disease immunopathology, systemic versus localized symptom presentation, patient preference, and desire to conceive should guide management options. Artificial insemination has the potential for severe adverse reactions in systemic SPH so necessitates extra procedural precautions. SPH does not appear to impair fertility. Additional research on specific allergens implicated in SPH can aid in the development of more targeted immunotherapy approaches with improved safety and efficacy.

Individual and household correlates of Helicobacter pylori infection among Young Ethiopian children in Ziway, Central Ethiopia.

BACKGROUND: Investigating distinct individual- and household-level risk factors for acquiring Helicobacter pylori (H. pylori) infection can inform disease prevention efforts and implicate possible routes of transmission. This study determined the magnitude of H. pylori infection among schoolchildren in Ziway, central Ethiopia and identified personal and household correlates of H. pylori infection in young Ethiopian children. METHODS: A total of 434 schoolchildren participated in this cross-sectional study. Infection status was assessed using antigen and antibody rapid tests. Demographic and lifestyle information was obtained from parents via an interviewer-led questionnaire. Univariate and multivariate logistic regressions were performed to assess the relationships between potential individual- and household-level risk factors and H. pylori infection. RESULTS: The prevalence of H. pylori infection was 65.7% (285/434). Of the personal variables assessed, the age group 10-14 years was found to be significantly associated with higher odds of H. pylori infection in univariate analysis (COR = 2.22, 95% CI: 1.06-4.66, p = 0.03) and remained positively correlated after adjusting for confounding factors. Of the household-level factors explored, having a traditional pit or no toilet was found to be significantly associated with 3.93-fold higher odds of H. pylori infection (AOR = 3.93, 95% CI: 1.51-10.3, p = 0.01), while the presence of smokers in the household was associated with 68% lower odds of infection (AOR = 0.32, 95% CI: 0.11-0.89, p = 0.03). CONCLUSION: This study from a developing country provides additional evidence for older age as a personal risk factor for H. pylori infection and identifies correlations between socioeconomic and sanitation household factors and positive childhood infection status. The associations reported here support the hypothesized fecal-oralroute of transmission for H. pylori.
