Abstract
Splenectomized and asplenic persons are at risk of developing sudden episodes of meningitis and/or septicaemia, frequently due to Streptococcus pneumoniae (overwhelming postsplenectomy infection, or OPSI). The application of staging splenectomy to patients with Hodgkin''s disease (HD) generated a new population at risk for OPSI. We reviewed the case, of sudden meningitis and/or septicaemia in a series of 491 consecutive adults with HD. No case was recorded among 149 non-splenectomized patients. 6 episodes of OPSI were observed in 5 of 342 splenectomized patients (crude frequency 1.75%, actuarial frequency at 10 yr 3.87%). The infecting organisms were S. pneumoniae (5 cases) and Salmonella enteritidis (1 case). 2 episodes (1 fatal) occurred during the first complete remission (CR), 15 and 120 months, respectively, after splenectomy. 4 episodes (2 fatal) occurred after first relapse. For splenectomized patients in continuous CR, the cumulative risk of OPSI was 2.30% (95% CL 0-6.10%), and it was 15.25% (95% CL 0-35.37%) for splenetomized patients who had relapsed. These data suggest that, in adults with HD, the risk of OPSI should not limit the indication to staging splenectomy and does not warrant systematic prophylaxis. However, in splenectomized relapsed patients, OPSI can be a troublesome complication and appropriate prophylaxis could be useful.
