Haemodialysis-related headache.

Area of Science:

• Nephrology
• Neurology
• Internal Medicine

Background:

• Dialysis-induced headaches, or dialysis headache (DH), are a significant complication of hemodialysis (HD).
• Understanding the frequency and characteristics of DH is crucial for patient management and improving quality of life during renal replacement therapy.

Purpose of the Study:

• To investigate the frequency and clinical characteristics of headaches occurring during hemodialysis.
• To explore potential associations between DH and patient demographics, dialysis parameters, and physiological changes.

Main Methods:

• A study involving 63 patients (30 female, 33 male) with chronic renal failure undergoing regular HD for at least six months.
• Diagnosis of DH followed International Headache Society criteria, excluding patients with primary headaches or confounding medications.
• Data collected included patient demographics, dialysis solutions (acetate or bicarbonate), dialyzer type, dialysis duration, and pre- and post-dialysis physiological measurements.

Main Results:

• Dialysis headache (DH) was detected in 48% of the study participants.
• DH showed a statistically significant difference in pre- and post-dialysis urea levels (P < 0.05).
• Patients with DH exhibited significantly higher mean pre-dialysis systolic (P < 0.001) and diastolic (P < 0.01) blood pressure compared to those without DH.

Conclusions:

• Dialysis headache (DH) is a common complication affecting nearly half of hemodialysis patients.
• DH is associated with significant changes in urea levels and elevated pre-dialysis blood pressure.
• The prevalent features of DH include fronto-temporal location, moderate severity, throbbing quality, and short duration (<4 hours).
