[A delicate balance: Gitelman syndrome and gestational diabetes. A case report]

Area of Science:

• Endocrinology
• Nephrology
• Genetics

Background:

• Gitelman syndrome (GS) is a rare autosomal recessive renal tubular disorder.
• GS is characterized by hypokalemia, hypomagnesaemia, metabolic alkalosis, hypocalciuria, and secondary hyperaldosteronism.
• The impact of GS on pregnancy, particularly the risk of gestational diabetes, remains unclear.

Observation:

• A case study of a pregnant patient with Gitelman syndrome who developed gestational diabetes.
• The patient required diligent electrolyte monitoring, especially in the first trimester.
• Altered glucose metabolism and insulin sensitivity have been noted in GS patients.

Findings:

• The case highlights the potential for gestational diabetes in pregnant women with GS.
• Assiduous ionic monitoring is crucial for managing maternal-fetal risks in GS pregnancies.
• A low-glucose diet may be beneficial in preventing gestational diabetes in this population.

Implications:

• This case underscores the importance of proactive management strategies for pregnant patients with Gitelman syndrome.
• Early dietary interventions, such as a low-glucose diet, could mitigate risks associated with gestational diabetes.
• Ensuring the maternal and fetal safety of medications affecting ionic balance is paramount.
