Rapidly progressive glomerulonephritis (RPGN) is a life-theatening nephritis with a rapid decline in renal function. In this paper, we examine the three alternative treatments relative to the most commonly-used oral steroid for the two prevalent forms of RPGN, called PautiCrGN and MPA, in Japan. The response “Exitus” is potentially non-ignorably missing because the data were reported by those who administered the treatment. We use the method proposed in Ibrahim (1996) for estimating parameters in binomial logistic model when the missing response is potentially nonignorable.For PautiCrGN patients, we found that the three alternative treatments did not seem to affect the survival of the patients. MPA patients who underwent the steroidpulse or the cyclophosphamide with the oral steroid, seemed less likely to have survived compared with those who received the oral steroid only.
