Allergy and Sexual Behaviours: an Update

Sexual activity and respiratory disease: A systematic review

CONTEXT

Sex and gender are related concepts, but they have distinct meanings and implications. Respiratory diseases are a major driver of morbi-mortality. It is frequent that respirologists, primary care doctors, or other specialists, when dealing with respiratory patients, and aiming for a holistic management of their patients, they all skip any question or matter associated with sexual activity or behavior.

OBJECTIVES

To review how sexual activity is explored in respiratory patients.

METHODS

To conduct this review, we endorse PRISMA guidance for reporting systematic reviews, and also the sex and gender equity in research (SAGER) guidelines.

RESULTS

Compared to other conditions such as heart disease, mental disorders, Alzheimer's, or even COVID-19, to date there is no review focused on sexual activity and respiratory health and disease. Asthma, COPD and other respiratory patients can have their sexual activity and behaviors affected by their disease, but also limitations in sex might be the sentinel event of an incident respiratory disease. Asking on sexual desire and related sex issues should not be considered taboo in any respiratory consultation. Importantly, any marketed stereotypes on cigarettes after any sexual activity should be counteracted. Many clinical trials of respiratory drugs keep recruiting few or no women, so research on women's sexual desire and satisfaction lags behind that of men's. By using the available objective tools and validated questionnaires summarized in this review, these important domains of respiratory patients and their partners can be properly identified and managed.

CONCLUSIONS

Sexual activity, depending on age and individual specific conditions, is a fundamental driver of overall health, and therefore of lung health.

Maintaining vulvar, vaginal and perineal health: Clinical considerations

Knowledge of female genital anatomy and physiology is often inadequate or incorrect among women. Precise patient-physician conversations can be inhibited by a reluctance or inability to speak accurately about the vulva and vagina, with the terms often being used interchangeably. There is a paucity of scientific evidence and clinical guidelines to support women and physicians in ensuring best practices in feminine hygiene. In this review, the unmet needs in the field are highlighted. Evidence is provided for the complex array of physiological and pathological systems, mechanisms and behaviours that either protect or, if inappropriate, predispose the vulva and vagina to infections, irritation or other conditions. The need for attention to perineal health is recommended, given the interdependence of perineal and vulvar microbiota and the risk of colonic pathogens reaching the vulva and the vagina. Differences in feminine hygiene practices can vary widely across the world and among varying age groups, and suboptimal habits (such as vaginal douching or the use of certain cleansers) can be associated with increased risks of vulvar and vaginal conditions. Critical areas for discussion when advising women on their intimate health include: advice surrounding aesthetic vulvar cosmetic trends (such as depilation and genital cosmetic surgery), bowel health and habits, and protection against sexually transmitted infections. Routine, once-daily (maximum twice-daily) washing of the vulva with a pH-balanced, mild cleanser is optimal, ideally soon after bowel voiding, when feasible. Due to the finely balanced ecosystems of the vulva, the vagina and the perineal area, a scientific and clinical perspective is essential when determining the most appropriate vulvar cleansers based on their components. Correct intimate care may contribute to improved genital and sexual health and overall well-being. An increased awareness of correct practices will empower women to be the advocates of their own intimate health.

The Relationship between Allergic Disease and Sexual Dysfunction: A Scoping Review

INTRODUCTION

Sexual dysfunction (SD) and allergic disease are common health concerns worldwide and bear a potential relationship. This scoping review is conducted to analyze the currently available data regarding the associations between these two health issues.

METHODS

A comprehensive literature search was performed in the databases of PubMed, MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science to retrieve studies that were published before January 2023. A narrative synthesis was conducted to analyze the effects of allergic diseases on SD based on the evaluation of the Female Sexual Function Index (FSFI) and International Index of Erectile Function (IIEF).

RESULTS

Twelve observational studies were included after the selection process. The results generally suggested lower FSFI or IIEF scores in patients with asthma, allergic rhinitis, allergic rhinoconjunctivitis, and urticaria compared to the healthy control groups. The underlying factors of this relationship could be inflammation, psychological factors, hormonal changes, sleep disorders, sexual behavior-related allergic reactions, social economic status, and the use of medications.

CONCLUSION

SD and allergic disease are interrelated based on the extant literature. This scoping review provides insights into the clinical implications of both entities, while more research studies are warranted to further elucidate this complex relationship.

Peanut-Induced Anaphylaxis in Children: A Literature Review

Peanut allergy has become more common among children and is considered one of the most common triggers for fatal anaphylaxis. Treatment of symptoms during a reaction is only one aspect of managing anaphylaxis; other elements include rigorous dietary avoidance and education about settings that could put the patient at a high risk of unintentional exposure. We aimed to review the prevalence, mechanism, diagnosis, treatment, and emergency action of peanut-induced anaphylaxis among children. We used a web-based literature search using the advanced features of databases such as PubMed, Scopus, Directory of Open Access Journals (DOAJ), Embase, Google Scholar, and Cochrane electronic databases. The most common food to cause fatal anaphylaxis and a common cause of food allergies is peanuts. Over the past two years, our knowledge improved more about peanut allergens, their prevalence, causes, diagnoses, and treatments. The research cited in this review demonstrates that the peanut allergens are most closely associated with disease differ across cultures, that early oral peanut exposure may reduce the occurrence of peanut allergy while early non-oral exposure may have the opposite effect, that complement activation by peanut constituents appears to promote peanut-induced anaphylaxis, and that oral immunotherapy, anti-IgE antibody, and a herbal formulation are all demonstrating promise as treatments. To conclude, peanut allergies have increased frequently during the past 10 years, especially in Westernized nations. Given that peanut allergy poses a danger for fatal anaphylaxis, response management is crucial. The current standard of care for those with nut allergies comprises complete food avoidance and the administration of injectable epinephrine to treat systemic symptoms.

Fatal anaphylaxis due to peanut exposure from oral intercourse

Background

Intimacy-related allergic reactions, including anaphylaxis, are under-reported due to social stigma, lack of awareness, and misdiagnosis. The differential diagnosis for intimacy-related anaphylaxis is extensive and includes systemic human seminal plasma allergy, exercise-induced anaphylaxis, asthma exacerbation, latex allergy, and transference of food or drug allergens through saliva or seminal fluid.

Case presentation

Two adolescents met on a popular dating phone application. One individual had a long-standing history of asthma and peanut allergy. Although they never kissed, the male with peanut allergy received fellatio, while the other male had eaten peanut butter before they met. During fellatio, the peanut allergic male developed respiratory symptoms, used his bronchodilator, and collapsed. He remained unconscious despite aggressive interventions by emergency personnel called to the site. The clinical history and autopsy results suggested anaphylaxis to peanut allergen exposure from the intimate exposure as the cause of death.

Discussion and conclusions

To date, nearly all reported cases of intimacy-related anaphylaxis involve symptomatic women. This is the first report of intimacy-related anaphylaxis involving men who have sex with men and the first report of potential allergen transfer from oral mucosa to a patient receiving fellatio. Based on the paucity of published cases, death from intimacy-related anaphylaxis is exceedingly rare. Post-mortem analysis is inherently difficult, as an elevated tryptase level has myriad potential causes; nevertheless, the authors suggest that intimacy-related anaphylaxis due to peanut allergy is the most likely diagnosis. With increasing popularity of relationship applications, especially amongst stigmatized populations, this case highlights the importance of allergy awareness and patient education to decrease risk, particularly in the adolescent population, who are already at increased risk of severe anaphylaxis. Especially amongst those participating in intimate activities, disclosure of one’s allergies warrants discussion, as the outcome can be fatal. Our case demonstrates the crucial need for increased advocacy in food allergy, education around intimacy-related anaphylaxis, and the importance of allergy awareness and prevention across all populations.

The combination of medical devices and medicinal products revisited from the new European legal framework

Medical devices and medicinal products have many similarities in their nature, scope or specific medical purposes, and despite the differences in their principal means of action, they are often used in combination. Indeed, many medicinal products depend on medical devices for their administration, and it is increasingly common for medical devices to contain medicinal substances to support their action. Therefore, the combination of medicinal products and medical devices provides additional benefits for patients. However, their higher technical complexity requires a strengthening of their authorisation and certification requirements. In this regard, more comprehensive requirements and classification rules are introduced by a new European regulation on medical devices that fully applies from May 26^th 2021. On account of their therapeutic significance, this review aims at gaining insight into the borderline between medical devices and medicinal products in this new 2021 regulatory framework. For the first time, any item containing a medical device and a medicinal product will have both parts evaluated. Through exemplification of both marketed and investigational devices incorporating medicinal substances and drug-device combinations, the new European requirements and their implications are thoroughly illustrated herein.

The Interplay of Atopic Dermatitis and Sexual Health

Atopic dermatitis (AD), a chronic inflammatory skin condition, negatively affects sexual health in various ways including causing physical discomfort and changes in physical appearance that can lead to low self-confidence. The chronic and debilitating nature of this disease can interfere with the sexual well-being of patients and their partners. This review describes the ways that AD affects sexual health. In addition, we review the impact that partnered relationships and physical intimacy can have on AD and provide practical recommendations for optimizing sexual health in AD patients.

Reversible Contraceptive Potential of FDA Approved Excipient N, N-Dimethylacetamide in Male Rats

Development of an effective male contraceptive agent remains a challenge. The present study evaluates the potential of N, N-Dimethylacetamide (DMA), a FDA approved excipient as a male contraceptive agent. Male Sprague Dawley rats injected with DMA for a period of 8 weeks (one injection per week) showed a significant alteration of reproductive parameters. Furthermore, DMA treated animals showed complete infertility in a dose dependent manner, as no pups were born despite proper mating between females and DMA treated males. However, stopping the DMA treatment for a period of 8 weeks (after the initial treatment) restored the reproductive parameters to normal. Moreover, the fertility was resumed to normal as pups were born in the groups where DMA treatment was halted after initial DMA treatment. All these changes had no effect on the level of reproductive hormones FSH, LH and testosterone. Taken together, our results indicate that DMA acts in a reversible and non-hormonal manner to achieve contraception in rats. Therefore, repurposing the use of DMA could lead in a short time to an inexpensive and safer male contraceptive option.

[Cutaneous and mucosal manifestations of sexual practices]

Sexual activity may on occasion be associated with local trauma, infections or allergies. During visits, patients may be reluctant to report on the circumstances leading to such lesions. The dermatologist may be unfamiliar with these manifestations, especially where they occur outside the genital area. Our aim is to present the spectrum of genital and extra-genital signs associated with sexuality. The dermatologist must feel sufficiently confident to broach the patient's sexual history in order to avoid any diagnostic errors and unnecessary explorations.

Sexual Functioning Is Frequently and Markedly Impaired in Female Patients with Chronic Spontaneous Urticaria

BACKGROUND

Chronic spontaneous urticaria (CSU) is common, chronic, and debilitating, and has serious effects on quality of life and mental health. Three of 4 patients with CSU are women. The impact of CSU on female sexual functioning remains largely unknown.

OBJECTIVE

To determine the prevalence of sexual dysfunction in female patients with CSU and to characterize their impairment of sexual functioning and its drivers.

METHODS

Fifty-six female patients with CSU and 55 female aged-matched healthy control subjects were evaluated for sexual functioning with the Female Sexual Function Index. Patients were also assessed for their duration, activity, and control of disease, as well as angioedema, anxiety, depression, fatigue, and quality-of-life impairment.

RESULTS

Sexual functioning, that is, total Female Sexual Function Index scores and all subscores, was markedly reduced in female patients with CSU versus control subjects, and 2 of 3 patients (67.9%) had sexual dysfunction. Impaired sexual functioning was linked to high disease activity and poor disease control. Sexual dysfunction was more common in patients with CSU with angioedema and vice versa. Angioedema was a significant predictor of sexual dysfunction in female patients with CSU (odds ratio, 7.3). Reduced sexual functioning was associated with anxiety, depression, and fatigue and significantly linked to impaired quality of life, more so in patients with angioedema as compared with those without.

CONCLUSIONS

CSU has strong negative effects on female sexual function, especially in patients with angioedema. Additional studies on sexual health in patients with CSU are needed and should focus on the impact of effective treatment on sexual functioning.

Intimate Contact Could Be Dangerous for Your Health

PURPOSE

To review evidence of hypersensitivity reactions to allergens and/or pathogens transmitted via intimate contact.

METHODS

We reviewed PubMed for publications in English between 1980 and 2018 using the terms allergy, drugs, foods, hypersensitivity, intercourse, kissing, Kounis syndrome, mast cells, and semen.

FINDINGS

In human RELATIONSHIPS, intimate contact can occasionally have disastrous or even fatal consequences because antigens and pathogens can be transmitted via the oral and vaginal mucosa. Hypersensitivity to semen is an underrecognized problem. Some individuals also developed acute coronary hypersensitivity, which mimics myocardial infarction, known as Kounis syndrome.

IMPLICATIONS

Hypersensitivity reactions to allergens and/or pathogens via intimate contact are common and should be recognized. Sensitive patients should be evaluated for atopic diathesis because such patients may be more susceptible and could also develop Kounis syndrome.
