ABSTRACT
BACKGROUND:
Worse outcomes from invasive pneumococcal disease (IPD) have been reported among those coinfected with hepatitis C. We aimed to establish if IPD notification rates are higher among people notified with markers of hepatitis C virus infection than the general population.METHODS:
IPD cases notified in Victoria, Australia, from July 2001-December 2017 were linked with hepatitis C cases (diagnosed by serology or PCR testing) notified from January 1991-December 2017. IPD incidence was calculated using population data and the estimated number of Victorians with hepatitis C.RESULTS:
From July 2001-December 2017, 6407 IPD cases were notified. Hepatitis C infection was notified in 342 (5.3%) of IPD cases overall, and 24.4% among IPD cases aged 45-49 years. Among IPD cases also notified with hepatitis C, 55.3% were infected with 13-valent pneumococcal conjugate vaccine serotypes and 82.8% with 23-valent pneumococcal polysaccharide vaccine serotypes. Compared with IPD cases without hepatitis C, IPD cases also notified with hepatitis C were younger (mean age, 45.7 vs 49.4 years; P = .011) and more often male (65.5% vs 55.5%, P < .001). Annual IPD notification incidence was 6.8/100 000 among people without hepatitis C and 39.4/100 000 among people with hepatitis C (IRR, 5.8; 95% CI, 5.2-6.4; P < .001).CONCLUSIONS:
IPD notification incidence was 5 times higher among people notified with markers of hepatitis C than the general population. Pneumococcal vaccination should be offered to people with markers of hepatitis C virus infection. To facilitate appropriate treatment, young and middle-aged adults with IPD should be tested for hepatitis C.Key words
