10-year study notes C diff incidence highest in Northeast
The incidence of hospitalization for Clostridium difficile infection (CDI) was highest in the Northeast and in the spring season, whereas C diff mortality rates were highest in the Midwest and in the wintertime, according to a large 10-year study of the disease across US regions published today in the American Journal of Infection Control.
University of Texas researchers analyzed 2.3 million cases of CDI from 2001 through 2010 and found the highest incidence in the Northeast, with 8.0 CDI hospital discharges out of 1,000 total discharges, followed by the Midwest (6.4), South (5.0), and West (4.8).
Seasonally, spring brought the highest incidence (6.2 /1,000), followed by winter at 5.9, summer at 5.9, and fall at 5.6. Adults and older adults followed overall trends, whereas pediatric CDI was highest in winter.
CDI mortality was highest in the Midwest, at 7.3%, compared with 6.9% in the Northeast and South and 6.2% in the West. The death rate was highest among seniors, at 8.8%, compared with 6.9% in working-age adults and 3.1% in children. Mortality peaked at 7.9% in the winter, compared with 6.8% in the summer, 6.6% in the fall, and 6.2% in the spring.
"The peak incidence in the spring could be attributed to increased utilization of antibiotics in winter months for respiratory infections," the authors wrote. "Prior studies have found a 1-2 month lag time between antibiotic exposure and the development of CDI."

Meningitis outbreak hits Niger, with serogroup C predominant
More than 1,500 cases of suspected meningococcal disease with nearly 150 deaths have been reported in Niger, the largest country in West Africa, since the beginning of the year, according to a notice today from the WHO. An international team from the WHO and the US Centers for Disease Control and Prevention is assisting in investigation and surveillance.
Seven of the country's eight regions have cited suspected meningitis, and cases have been confirmed in Dosso region and in Niamey, the capital and largest city. Neisseria meningitides serogroup C has been shown through laboratory testing as predominant in samples from affected areas, with serogroup W also present.
The notice gives the total suspected cases through Apr 25 as 1,543 and the number of deaths as 147. Just last week the WHO reported only 461 cases and 62 deaths in Niger through Apr 5. Mass vaccination campaigns, case management, and social mobilization actions are under way.
