An observational study in Cramps and Chronic Kidney Disease(CKD), sponsored by Assistance Publique - Hôpitaux de Paris. Not yet recruiting at 1 site in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2024-12-17.
Sponsored by Assistance Publique - Hôpitaux de Paris · Observational
Cramps are a frequent and severe complication in CKD patients. Their characteristics : triggering factors, associated factors, are not well known. There is no recognized effective treatment. Using a questionnaire, the investigators wish to determine prevalence, severity and associated factors of cramps in our CKD patients. Better knowledge about cramps in CKD patients will allow to better support, and give a practical tool for treatment evaluation.
The investigator have elaborated a specific questionnaire for our CKD patient about cramps. This questionnaire concerns only cramps, regardless of the origin. The first question of the questionnaire will allow to evaluate the prevalence of cramps in our population of CKD patients. Every patient will indicate his medical treatment and biological datas. Only patients who will answer " Yes " to the first question will complete the cramp score of gravity questionnaire. This score is composed of 4 items : frequency of crisis, there impact on sleep, there duration and there intesity Patients will also indicate for how long time there have experimented cramps, the muscular zones involved, associated symptoms, triggering factors, and does something can help them for cramps (medicinal or non medicinal).
The third part concerns there treatment and biological datas. Finally there will complete the QOL-SF12 questionnaire.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
