Different seasonal variations in dialytic parameters, especially blood pressure have been observed in different parts of the world. In this study we followed the seasonal variation of a number of clinical parameters in a group of chronic hemodialysed patients in southern Morocco. This is a 28 months retrospective study, from May 2007 to September 2009 in the military hemodialysis center of Agadir in southern Morocco, where were listed different dialysis clinical parameters over time (days and months) and compared during two periods: cold period and warm one. During the study period, 16,000 renal epuration therapy sessions were performed. A significant seasonal variation was observed regarding inter-dialysis weight gain (IDWG), blood pressures (systolic, diastolic and mean) before and after dialysis. The ultrafiltration rate values were lower during warm while intra-dialysis hypotension was more common during the cold period. We conclude that there is seasonal variation of a number of dialytic parameters that must be kept in mind during the clinical monitoring of renal purification treatment sessions especially in areas with large variations in temperature.
