I would like to thank Dr Wardle for his comments on our Review [1]. Actually ACEIs are generally very well-tolerated drugs and in our experience, very few patients have to abandon this therapy owing its side effects [2]. This is even more true for ARBs.
I agree with Dr Wardle, that a possible explanation of the difference among patients could be related to racial/pharmacogenetic factors. The message we wished to convey was to use inhibitors of reninangiotensin II system in patients with IgA nephritis and clinically relevant proteinuria, before using steroids or immunosuppressants.
Moreover, considering that the control of blood pressure is of paramount importance, very often the addition of calcium channel blockers is required, in order to reach the blood pressure target values suggested by the Guidelines. We would like to underline the fact that just using inhibitors of renninangiotensin II system, without carefully considering the blood pressure values actually reached, is a very frequent wrong therapeutic approach.
We agree with the relevance of thromboxane to the pathophysiology of IgA nephritis and a possible prescription of a small dosage of aspirin, in patients who can tolerate it (unfortunately the number of these patients is much lower than the number of patients who can tolerate inhibitors of reninangiothensin II system!).
In the case of rapidly progressive IgA nephritis, as we have already emphasized [23], we should be more aggressive, using cytotoxic drugs, possibly including mycophenolate mofetil, which seems much more manageable than Melphalan.
