Objective: To explore the risk factors associated with acute/subacute cerebral infarction (ASCI) in HIV-negative patients with cryptococcal meningitis (CM).
Methods: This case-control study included 10 HIV-negative CM patients with ASCI and 30 age- and sex-matched HIV-negative control (1:3) CM patients without ASCI. The clinical manifestations and neuroimaging findings were collected. Risk factors for ASCI in the HIV-negative CM patients were confirmed by conditional logistic regression analysis.
Results: Among the 10 HIV-negative CM patients with ASCI, all cases had lacunar infarctions. Single infarctions were found in 6 patients, and multiple infarctions in 4. Hydrocephalus (p=0.020, OR=23.77, 95% CI, 1.67-339.33) and smoking (p=0.039, OR=11.63, 95% CI, 1.14-118.96) were found to be independently associated with the occurrence of ASCI.
Conclusions: Hydrocephalus and smoking may increase the risk of ASCI in HIV-negative CM patients. In the clinical course, cerebral infarction should be strongly suspected in CM patients with hydrocephalus or smoking histories.
