High frequency of nocturnal hypertension in lupus nephritis: should ABPM be implemented in usual practice?

Due to the high frequency of nocturnal hypertension and abnormal day-to-night dipping, office BP measurements alone may not be sufficient to guide hypertension management in patients with LN.Key Points• Nocturnal hypertension and abnormal BP patterns are frequent and not detectable by the standard in-office BP evaluation in LN patients.• BP abnormalities may not be fully corrected after a complete clinical response to treatment in lupus nephritis and are only detectable by ABPM.• The degree of interstitial inflammation in the kidney biopsy in LN patients is associated to BP levels. This supports the hypotheses underlining the role of interstitial inflammation in salt sensitivity and hypertension.
