- Abstract
Background C-reactive protein (CRP) is an acute-phase protein produced by the liver in response to systemic inflammation. CRP is a helpful surrogate biomarker widely used in various infections, particularly for following the progression and resolution of infection. We aimed to determine the association between baseline CRP level and cryptococcal meningitis outcome. Methods We reviewed 168 prospectively enrolled HIV-infected Ugandans with confirmed first-episode cryptococcal meningitis. Baseline serum samples collected within 5 days from diagnosis had CRP levels measured and categorized into quartiles. We compared baseline serum CRP with 18-week survival using unadjusted time-to-event analysis. Results Of 168 participants, the first quartile of baseline serum CRP was 83.6 mg/L. Baseline CD4 count, HIV viral load, and cerebrospinal fluid results did not differ by quartile. Participants with CRP > 49.5 mg/L more likely presented with Glasgow Coma Scale <15 (P = 0.03). The 18-week mortality rate was 54.8% (46/84) in the highest two quartile CRP groups (49.5 mg/L), 40.5% (17/42) in the mid-range CRP group (29–49.5 mg/L), and 14.3% (6/42) in the low CRP group (<29 mg/L) (P < 0.001) (Figure 1). Conclusion Higher baseline serum CRP is associated with increased mortality in HIV-infected individuals with first-episode cryptococcal meningitis. The serum CRP could be a surrogate marker for undiagnosed co-infections or may reflect immune dysregulation leading to worse outcomes in persons with advanced AIDS and concomitant cryptococcal meningitis. Additional studies investigating more specific inflammatory biomarkers and the longitudinal trend in CRP with effective therapy would be informative. Disclosures All authors: No reported disclosures.
