Purpose To determine the prevalence of allergy in couples undergoing in vitro fertilization (IVF) and the relationship between having allergy and IVF treatment outcomes. Design A retrospective cohort study of female infertility patients aged 20-49 years and their male partners undergoing IVF cycles from August 2010 to December 2016 in an academic fertility program. Results Prevalence data was collected for 493 couples (935 cycles). Over half of the female patients (54%) had at least one reported allergy versus the cited US prevalence of 10-30%. Antibiotic (54.7%) and non-antibiotic medication (39.2%) were the most common female allergy subtypes. Fewer male patients reported allergy (21.7%). Data on β-hCG outcomes were calculated for 841 cycles from 458 couples with no significant relationship found except for number of cycles including ICSI and number of embryos transferred per cycle (1.81 for those without allergy vs 2.07 for those with allergy, p = 0.07). Female patients with allergy were marginally statistically more likely to have a negative β-hCG (p = 0.07) and less likely to have a successful cycle (p = 0.06). When allergy subgroups were evaluated, there were no significant differences between groups except for a higher number of embryos transferred in women with environmental/other allergies (p = 0.02).
ConclusionThe prevalence of allergy among patients seeking infertility treatment is high compared with the general population. However, allergy was not found to be associated with IVF cycle outcomes. These findings are likely primarily limited by difficulty in defining specific allergy types within a retrospective study.
The SARS‐CoV‐2 pandemic was announced in March 2020, with the first vaccines becoming available later that year. Although generally well tolerated, there have been reports of skin reactions occurring after receiving COVID‐19 vaccines, with a rare occurrence of granuloma annulare. Granuloma annulare can occur secondarily to herpes zoster infection in a phenomenon known as Wolf's isotopic response (WIR). WIR has been described to often occur after herpes zoster virus infection, at the location of the healed shingles rash, termed ‘post‐herpetic isotopic response' (PHIR). We present the first reported case of PHIR with granuloma annulare after the Moderna COVID‐19 vaccination series. This reported reaction should not limit receipt of the COVID‐19 vaccine, but awareness of this association can minimise additional work‐up and treatment.
Lyme disease is commonly encountered in endemic areas of the United States harboring the causal organism Borrelia burgdorferi. Lyme carditis can manifest in early disseminated infections, usually as atrioventricular nodal blockade. Timely antibiotic therapy typically suppresses myocardial inflammation and reverses cardiac conduction disturbances. We present a case of a previously healthy male who presented to the emergency department with non-prodromal syncope, multifocal annular rashes, and antecedent inflammatory knee pain and effusion, found to have positive 2-tier Lyme testing and pause-dependent polymorphic ventricular tachycardia leading to cardiac arrest. Lyme carditis occurs in early disseminated infections but rarely leads to cardiac arrest. Acute management is entrained in well-established guidelines for therapy, and together with risk stratification scoring can be considered by emergency care physicians in the workup of undifferentiated syncope with concern for Lyme disease with cardiac involvement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
