How do I manage my fertility with lupus nephritis at 29?

Question

Hi doctor,

I am 29 years old and was recently diagnosed with lupus nephritis after my kidney function began to decline rapidly. My creatinine level has increased from 1.2 to 2.8 mg/dL in just two months, and I am spilling large amounts of protein in my urine (4+ on dipstick testing). My rheumatologist wants to start me on Cyclophosphamide, but I am trying to get pregnant, and this drug can severely affect fertility.

I have already had two miscarriages in the past year, and I am now wondering whether they were related to lupus. My blood pressure is very high at 165/95 despite being on Lisinopril, and I am retaining so much fluid that I have gained 20 pounds in three weeks. The joint pain in my hands and knees is so severe that I can barely continue working as a teacher.

My antinuclear antibody (ANA) test is positive at a titer of 1:640 with a speckled pattern, and my complement levels are very low. I am experiencing severe fatigue and brain fog, which makes it difficult to concentrate on lesson planning.

What fertility-sparing treatment options are available for lupus nephritis, and should I avoid pregnancy altogether?

Please help.

Hi,

Welcome to icliniq.com.

I understand your concern.

Your desire for pregnancy is completely valid. It is absolutely possible to conceive and have a healthy pregnancy with lupus nephritis, but only when the disease is well-controlled and managed with pregnancy-safe medications. Trying to conceive while lupus is active and threatening kidney function would be dangerous for both you and the baby.

Active lupus, especially with high disease activity and low complement levels like yours, is strongly associated with pregnancy loss. This is not your fault, and it is very common in poorly controlled disease.

Key points for a safer future pregnancy include achieving remission of lupus nephritis for at least six months before conceiving, having stable kidney function with creatinine ideally below 1.4 mg/dL, controlling proteinuria and blood pressure, being on pregnancy-compatible medications such as Hydroxychloroquine, Azathioprine, or Tacrolimus, and receiving multidisciplinary care involving a maternal–fetal medicine specialist.

Regarding fertility preservation, oocyte (egg) or embryo freezing before starting Cyclophosphamide is a valid option if your health status and timing allow. This is usually done in collaboration with a fertility specialist, along with your rheumatologist and nephrologist.

You are currently facing active lupus nephritis with worsening kidney function, severe hypertension, heavy proteinuria, significant symptoms, and fertility concerns at a young age. Cyclophosphamide is a potent immunosuppressive medication commonly used for severe proliferative lupus nephritis, such as class III or IV disease, because it can induce remission and help preserve kidney function. However, it carries significant risks related to fertility.

I hope this has helped you.
