Pregnancy in PCOS: A Comprehensive Approach to Maternal and Fetal Health

Introduction: Features of Pregnancy in PCOS and Comorbid Conditions

Polycystic ovary syndrome (PCOS) is a common endocrine disorder that can affect reproductive function and the course of pregnancy. Women with PCOS, like any other expectant mothers, may encounter various medical conditions that require careful management during pregnancy. Although the presented scientific publications do not directly address the treatment of PCOS during gestation, they emphasize general principles and approaches for managing comorbid conditions, which are crucial for ensuring maternal and fetal health. These principles include preconception preparation, careful selection of drug therapy, active monitoring, and timely management of potential complications.

The Importance of Preconception Preparation and Planning

Optimal pregnancy management begins long before conception. For women with chronic diseases, including PCOS and other conditions, preconception preparation is critically important. The goal is to achieve control over the underlying disease before pregnancy occurs [4, 5, 6]. This helps minimize risks to the mother and fetus associated with disease activity or the need to use potentially harmful medications during pregnancy.

• Assessment of disease activity: Before conception, it is necessary to assess the current activity of the chronic disease, organ involvement, and the serological profile [6].
• Risk stratification: An assessment of individual risks associated with pregnancy is performed, taking comorbid conditions into account [6].
• Therapy adjustment: If necessary, medical treatment is adjusted to switch to medications safe for use during pregnancy and lactation [4, 5].

Thorough planning and consultations with specialists (gynecologist, endocrinologist, rheumatologist, dermatologist, and others as indicated) allow for the development of an individualized pregnancy management plan, which is especially relevant for women with PCOS who may have increased risks of gestational diabetes, preeclampsia, and other complications.

Drug Therapy During Pregnancy: Balancing Benefits and Risks

The choice of drug therapy during pregnancy always requires a careful evaluation of the benefit-to-mother versus potential risk-to-fetus ratio. Many, but not all, medications used to treat chronic conditions can be continued or initiated during pregnancy and lactation [4, 5].

For example, in dermatological conditions such as eczema, which is common during pregnancy, it is important to ensure effective treatment, especially for moderate-to-severe forms [8]. If topical agents or phototherapy are ineffective, systemic therapy may be required, but its selection must be carried out by dermatologists considering safety for pregnant women [8]. A general review of dermatological medications during pregnancy emphasizes the need for a cautious approach to the treatment of acne, psoriasis, bacterial, fungal, viral, and parasitic infections, as well as the use of antipruritics, analgesics, and local anesthetics [1].

Similar principles apply to other chronic conditions. Women with rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE) may need to continue certain antirheumatic drugs, many of which are considered safe during this period [4, 5]. It is important that treatment is aimed at preventing disease flares, as they can lead to complications such as preeclampsia, small-for-gestational-age infants, and preterm birth [4, 5].

Monitoring and Management of Comorbid Conditions

Regardless of the presence of PCOS, pregnancy requires careful clinical monitoring, especially in the presence of comorbid diseases [4, 5, 6]. Timely detection and treatment of complications are crucial for a successful outcome [3, 7].

Examples of conditions requiring special attention:

• Uterine fibroids: A common phenomenon in obstetric practice, especially against the background of delayed childbearing and rising obesity. Fibroids can affect the course of pregnancy, although data on optimal management tactics are often contradictory [2]. A careful evaluation of their characteristics, behavior, and potential complications is required [2].
• Autoimmune diseases: Women with RA, SLE, and obstetric antiphospholipid syndrome (APS) require anticoagulant therapy for APS and control of disease activity to prevent flares and pregnancy complications [4, 5, 6].
• Arrhythmias: The development of new atrial fibrillation (AF) during pregnancy is rare, but requires early recognition and treatment, as it can negatively affect maternal and fetal hemodynamics [3]. In cases of medical-refractory AF, as described in one case, an individualized approach is required [3].
• Gestational diabetes insipidus: This condition is often underestimated because polyuria may be mistakenly considered normal for pregnancy. However, its screening is important as it may be associated with a serious underlying pathology [7].

Continuous monitoring and an interdisciplinary approach allow for a prompt response to changes in the pregnant woman's health status and adjustment of the treatment plan.

Potential Pregnancy Complications and Their Prevention

Pregnancy, especially in the presence of chronic diseases, is associated with the risk of various complications. Women with conditions such as RA or SLE are characterized by increased risks of preeclampsia, small-for-gestational-age infants, and preterm birth [4, 5, 6].

Prevention of these complications includes:

• Control of the underlying disease: Maintaining remission or low activity of the chronic condition before and during pregnancy [4, 5, 6].
• Early diagnosis and treatment: Timely detection and adequate treatment of any emerging issues, whether it is an autoimmune disease flare [6], the onset of atrial fibrillation [3], or the development of gestational diabetes insipidus [7].
• Specialized monitoring: Regular visits to physicians of various specialties and completion of all recommended examinations.

For women with PCOS, these principles are also important because they may have an increased risk of some of the listed complications, making a comprehensive approach to pregnancy management even more relevant.

Postpartum Period and Further Follow-Up

Monitoring a woman's health does not end with childbirth. The postpartum period (puerperium) also requires careful observation, especially for patients with chronic diseases [6]. This makes it possible to control disease activity, prevent potential flares, and timely adjust therapy, taking into account the lactation period. Consultations on reproductive health and planning future pregnancies are also an important part of postpartum care.
