Antenatal herpes virus infection is one of the most common infections affecting women during pregnancy. The most well-known causative agents of this infection are herpes simplex virus types 1 and 2 (HSV-1 and HSV-2), which can lead to serious consequences for both the mother and the fetus. Herpes virus infection during pregnancy can occur both before conception and during pregnancy. Possible negative outcomes include premature birth, intrauterine infections, and even neonatal death. The infection can recur, making it difficult to treat. Understanding the pathogenesis, clinical presentation, and diagnostic methods is fundamental to preventing complications associated with this disease.
History of the disease and interesting historical facts
The history of studying herpes infection dates back to ancient times. The first mentions of rashes resembling herpes can be found in the works of Hippocrates, who described "water blisters" on the skin. However, the name "herpes" itself comes from the Greek word "herpes", which translates as "creeping", which reflects the characteristic course of the inflammatory process. In the 19th century, it was established that the rashes that occur with this infection are caused by a virus, and since then, active study of the herpes virus has begun within the framework of microbiology and virology. In 1919, the HSV-1 virus was isolated and identified, which gave impetus to further research. Interestingly, it was previously believed that herpes is primarily a sexually transmitted disease, but it was subsequently established that herpes can be transmitted in other ways, including through contact with affected skin.
Epidemiology
According to the World Health Organization, the herpes simplex virus has infected approximately 67% of the world's population under 50 years of age. In women, the prevalence of infection can reach 90%, especially among those who are sexually active. The epidemiology of prenatal herpes virus infection points to a growing problem: according to recent studies, the number of herpes infections in women of reproductive age is increasing. Preventive measures and timely diagnosis are especially important in risk groups based on socio-economic factors, educational level and access to health care. Thus, controlling the spread of infection is an urgent task for health care worldwide.
Genetic predisposition to this disease
Although the herpes virus is not genetically inherited, genetic predisposition to diseases caused by this pathogen may manifest itself. Research shows that certain genes associated with the immune response may influence susceptibility to the virus. For example, variations in genes responsible for the production of interferons or cellular receptors may determine the level of protection against herpes infection. The main factor contributing to predisposition to herpes is considered to be the main role of T-lymphocytes, which may be disrupted due to mutations or polymorphisms in the corresponding genes. It is also important to consider that in families where one of the parents suffers from herpes infection, the likelihood of transmitting predisposition increases.
Risk factors for the development of this disease
Risk factors for developing herpes virus infections can be divided into several categories:
- Physical factors:
- immunodeficiency states (eg, HIV, autoimmune diseases);
- pregnancy;
- stress and fatigue.
- Chemical factors:
- long-term use of immunosuppressants;
- influence of toxic substances (eg alcohol, drugs);
- lack of vitamins and minerals.
- Social factors:
- multiple sexual partners;
- living in conditions of high population density;
- lack of awareness about infection prevention.
Diagnosis of this disease
Diagnosis of herpes virus infection requires a comprehensive approach and includes several stages:
- Main symptoms:
- formation of blisters and ulcers on the skin and mucous membranes;
- systemic symptoms (fever, headache);
- pain in the area of the rash.
- Laboratory tests:
- PCR (polymerase chain reaction) to detect viral DNA;
- serological testing to determine antibodies;
- Monochromatic staining for visualization of viral particles.
- Radiological examinations:
- Ultrasound examination to assess the condition of the fetus;
- MRI for the assessment of lesions in neurological forms of infection.
- Other types of disease diagnostics:
- biopsy to determine the type of infection;
- clinical examination by a dermatovenerologist.
- Differential diagnosis:
- psoriasis;
- eczema;
- lesions caused by other viruses (eg, HPV).
Treatment
Treatment of herpes virus infection includes several areas:
- General treatment:
- ensuring peace, adequate nutrition;
- continuous monitoring of health status.
- Pharmacological treatment:
- antiviral drugs (acyclovir, valacyclovir);
- immunomodulators to stimulate the body's defense mechanisms.
- Surgical treatment:
- performing surgery in complicated forms (for example, genital herpes with the formation of fistulas);
- plastic surgery of affected areas.
- Other types of treatment:
- physiotherapy (e.g. UV radiation);
- psychological support to reduce stress.
List of medications used to treat this disease
- Acyclovir;
- Valaciclovir;
- Famciclovir;
- Immunomodulators (eg, interferons);
- Analgesics (for pain relief).
Disease monitoring
Monitoring for herpes virus infections includes:
- Regular check-ups with your doctor to assess your condition;
- Monitoring viral load levels;
- Prognosis: Most cases are favorable with adequate treatment;
- Complications: risk of transmission of the virus to the fetus, especially with primary infection during pregnancy.
Age-related features of the disease
The herpes virus can manifest itself differently depending on the patient's age. In newborns, a severe form of infection is possible, leading to meningitis and encephalitis. In school-age children, relapses of the disease are more common, which can affect the quality of life. In adults, especially women of reproductive age, herpes often manifests itself in the form of relapses, which is associated with changes in hormonal levels, stress and features of the immune response.
Questions and Answers
- How is the herpes virus transmitted?
The virus is transmitted through direct contact with infected areas of the skin or mucous membranes, as well as through saliva and sexual intercourse. - What are the symptoms of herpes virus infection?
The main symptoms include painful blistering rashes on the skin or mucous membranes, fever, headache and fatigue. - Can herpes virus infection be prevented?
Basic preventive measures include maintaining personal hygiene, avoiding casual sex and using barrier methods of contraception. - How long does a herpes outbreak last?
An exacerbation can last from 7 to 14 days, but with the right treatment the period can be reduced. - Is it safe to have children if I have a herpes virus infection?
Most women with herpes infection can have healthy children, but regular monitoring by a doctor is necessary to prevent complications.
Advice from Dr. Oleg Korzhikov
In the presence of herpes virus infections, especially during pregnancy, it is important to follow the recommendations of a specialist. Start treatment as early as possible to reduce the risk of transmission. To prevent relapses, try to avoid stress and support immunity with vitamins and good nutrition. Also, do not forget about the mandatory use of barrier contraception in case of exacerbations to protect your partner. At the first signs of the disease, consult a doctor to prescribe adequate therapy.
