Successful pregnancy in a CKD patient on a low-protein, supplemented diet: an opportunity to reflect on CKD and pregnancy in Mexico, an emerging country

Abstract

Pregnancy is probably the most important challenge in young women with chronic kidney disease (CKD). The challenge is greater in developing countries, in which access to dialysis is uneven, and prenatal care for CKD patients is not uniformly available. This case report summarizes some of the challenges faced by pregnant CKD women in a developing country. A 35-year-old woman, affected by an undiagnosed kidney disease, experienced preeclampsia at 24 years of age, and started dialysis in emergency at age 31 in the context of severe preeclampsia in her second pregnancy. Following slow recovery of kidney function, after 18 months of dialysis she started a moderately restricted, supplemented, low-protein diet, which allowed her to discontinue dialysis. A few months after dialysis discontinuation, she started a new pregnancy in the presence of severely reduced kidney function (serum creatinine 4.6 mg/dl at the last pre-pregnancy control). Interestingly, she discontinued nephrology and nutritional follow-up, mainly because she was worried that she would be discouraged from continuing the pregnancy, but also because she continued to feel well. She self-managed her diet in pregnancy and delivered a healthy baby, with normal intrauterine growth, at term; while the last laboratory data confirmed the presence of severe kidney function impairment, she is still dialysis-free at the time of the present report. Her story, with its happy ending, underlines the importance of dedicated programs for CKD pregnancies in developing countries and confirms the safety of moderately protein-restricted diets in pregnancy.
