From the Guidelines

Lupus can indeed affect menstrual cycles, causing irregularities in many women with this autoimmune condition, and managing the underlying lupus activity is crucial to normalize menstrual cycles. If you're experiencing irregular periods with lupus, consult your rheumatologist and gynecologist for a comprehensive evaluation. Treatment typically involves managing the underlying lupus activity with medications like hydroxychloroquine (Plaquenil), corticosteroids, or immunosuppressants, which may help normalize menstrual cycles as overall inflammation decreases 1. For specific menstrual management, hormonal contraceptives like birth control pills (containing estrogen and progesterone) may be prescribed to regulate cycles, though these should be carefully selected as some lupus patients, particularly those with antiphospholipid antibodies, may have increased clotting risks 1.

Some key points to consider in the management of lupus and irregular menstruation include:

  • The use of hormonal contraception or replacement therapy must be weighed against the individual risk of thrombosis 1
  • The preservation of fertility should be mentioned while counselling about lifestyles and considered in the treatment choice 1
  • Predictive biomarkers for maternal disease activity during SLE pregnancy should be expanded with particular focus on the prediction of pre-eclampsia 1
  • Pregnancy monitoring in SLE and/or APS women should aim at the identification of placental insufficiency with fetal growth restriction in order to decide the best timing for delivery and reduce the risk of perinatal morbidity and mortality 1

Non-hormonal options like NSAIDs (ibuprofen or naproxen) can help with menstrual pain and heavy bleeding. The connection between lupus and menstrual irregularities stems from systemic inflammation affecting the hypothalamic-pituitary-ovarian axis, disrupting normal hormone production. Additionally, medications used to treat lupus, particularly corticosteroids, can independently affect menstrual cycles. Keep a detailed menstrual calendar to share with your doctors, noting cycle length, flow amount, and any symptoms that coincide with lupus flares to help identify patterns and guide treatment.

It is also important to consider the potential impact of lupus on fertility, and the use of fertility preservation methods such as gonadotropin-releasing hormone analogues (GnRH-a) may be recommended for women with SLE who require treatment with alkylating agents 1. Furthermore, the use of hydroxychloroquine during pregnancy may help reduce the risk of SLE flares and poor obstetrical outcomes 1.

From the Research

Lupus and Irregular Menstruation

  • Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect menstrual cycles in women, with studies showing a higher prevalence of menstrual irregularities in SLE patients compared to the general population 2, 3.
  • Menstrual disturbances in SLE patients can be caused by various factors, including disease activity, treatment with immunosuppressive agents, and hormonal imbalances 2, 4.
  • Research has shown that SLE patients with higher disease activity, as measured by the SLEDAI score, are more likely to experience menstrual irregularities 2.
  • The use of immunosuppressive agents, such as cyclophosphamide and azathioprine, has been associated with an increased risk of menstrual disturbances in SLE patients 3, 4.
  • Menstrual irregularities can have significant health implications, including an increased risk of metabolic syndrome, coronary heart disease, type 2 diabetes mellitus, and rheumatoid arthritis 5.

Prevalence of Menstrual Irregularities in SLE Patients

  • Studies have reported a prevalence of menstrual irregularities in SLE patients ranging from 37.9% to 49% 3, 4.
  • The most common type of menstrual irregularity in SLE patients is sustained amenorrhea, which can be a sign of premature menopause 3.
  • Menstrual irregularities can also be associated with other health problems, such as anemia, osteoporosis, and psychological problems 5.

Treatment and Management of Menstrual Irregularities in SLE Patients

  • Treatment with hydroxychloroquine (HCQ) has been shown to be effective in achieving prolonged remission in SLE patients, with no significant difference in the weight-adjusted dose of HCQ between patients who achieved remission and those who did not 6.
  • The use of HCQ at stable doses of 200 mg/day (or 3.0-3.5 mg/kg/day) as background therapy in SLE patients can help achieve prolonged remission, with the majority of patients achieving remission 6.
