[The CROFF pavilion at the Policlinico Hospital in Milan: the beginnings].

This article collects the personal stories of the young doctors who in the early sixties contributed to the birth and development of the Croff pavilion at the Policlinico Hospital in Milan. Inaugurated on October 19, 1964, this has been the first institute in Italy entirely devoted to patients with kidney diseases. Since its inception, it has significantly contributed to the progress of nephrology thanks to important and pioneering investigations in the main fields of our specialty, which still continue nowadays. The different stories reported here follow the chronological order in which the young doctors arrived at Croff, each story representing a personal narrative that interweaves and integrates that of others. This gives rise to a vivid many-voiced account, from which emerge not only the figures of these young doctors, but also those of patients, nurses, and laboratory technicians.

Withdrawal of therapy in patients with proliferative lupus nephritis: long-term follow-up.

BACKGROUND: Whether corticosteroid and immunosuppressive therapy may be safely withdrawn in patients with proliferative lupus nephritis is still unclear. METHODS: In 32 patients with biopsy-proven proliferative lupus nephritis previously put into remission, therapy was gradually tapered off. RESULTS: When immunosuppressive therapy was stopped (median: 38 months; 25th-75th percentile: 24-81 months, after biopsy), 24 patients were in complete remission and eight had a median proteinuria of 1.05 g/24 h (25th-75th percentile: 0.91-1.1 g/24 h) with normal renal function. After stopping therapy, patients were followed for a median of 203 months (25th-75th percentile: 116-230 months). Fifteen patients (Group 1) never developed lupus activity. The other 17 patients (Group 2) developed lupus exacerbations in a median of 34 months (25th-75th percentile: 29-52 months) after stopping therapy and were re-treated. The only significant differences between the two groups were the longer median durations of treatment, 57 months (25th-75th percentile: 41.5-113.5 months) vs 30 months (25th-75th percentile: 18-41 months; P<0.009), and remission, 24 months (25th-75th percentile: 18-41) vs 12 months (25th-75th percentile: 7-20 months; P<0.02), before stopping therapy in Group 1 than in Group 2. At last follow-up, 12 patients of Group 1 were in complete remission, two had mild proteinuria and one had died. In Group 2, one patient died, 14 were in complete remission, one had mild proteinuria and in another patient serum creatinine doubled. CONCLUSIONS: Some patients with severe lupus nephritis who enter stable remission can be maintained without any specific treatment for many years. Those patients who have new flares can again go into remission with an appropriate treatment. The longer the treatment and remission before withdrawal, the lower the risk of relapse.
