Clinical Characteristics, Symptoms, and Long-Term Outcomes in Gitelman Syndrome
Bibliographic record
Abstract
Introduction: Gitelman syndrome (GS) is a rare inherited salt-losing tubulopathy with limited clinical data. Methods: Surveys were conducted with GS physicians in Europe and patients with GS in the Netherlands to compare findings with the general population. Results: . Children with GS were shorter and lighter than the general population, with lower bodyweight persisting into adulthood. The sex distribution was uneven, with more males in childhood and more females in adulthood. Patients with GS had the expected electrolyte disorders as well as significantly lower blood phosphate levels. Positive correlations were found between blood magnesium and potassium, and potassium and aldosterone. Physicians reported muscle cramps, salt craving, and muscle weakness as most common GS symptoms. Patients with GS scored worse than the general population in fatigue, physical, and cognitive function; and ranked salt craving and polydipsia-polyuria as the most severe symptoms. Symptom burden was higher in adult females and patients with lower blood magnesium. Treatment mainly consisted of potassium (94%) and magnesium (50%) supplementation. Potassium-sparing medication (used in 33%) slightly increased blood potassium levels (3.2 vs. 3.1 mmol/l). Adult patients with GS had a high prevalence of chondrocalcinosis (15%) and elevated blood cell counts (26%). Compared with the general population, adult patients with GS had lower rates of chronic kidney disease (CKD) and hypertension, a similar rate of diabetes, but a higher rate of albuminuria or proteinuria (28%). Conclusions: These findings provide new insights into GS, highlight disease burden, and suggest areas for future research.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
