Pre-Pregnancy Diabetes Increases Risk Of MRSA For New Mothers

Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium responsible for several difficult-to-treat infections in humans. MRSA is any strain of Staphylococcus aureus that has developed through the resistance to beta-lactam antibiotics.

The most common physical manifestations of MRSA are skin infections such as necrotizing fasciitis, also known as flesh-eating disease.

MRSA infections are more difficult to treat with standard types of antibiotics and thus are more dangerous if contracted. These types of infections are especially common in hospitals, prisons, and nursing homes where patients incur treatment for open wounds. Those with weakened immune systems, such as the cancer sufferers or those with HIV/AIDS, are especially vulnerable. An inability to treat can lead to death.

A study – published in the July issue of the American Journal of Infection Control, a publication of the Association for Professionals in Infection Control and Epidemiology (APIC) – suggests pregnant women with diabetes are three times more likely to become infected with MRSA before being discharged from the hospital.

The research aimed to investigate the risk association of pre-pregnancy and gestational diabetes and MRSA following delivery. A link between pre-pregnancy diabetes was established, whereas one was not found with gestational diabetes, reports Medpage Today.

Researchers from the University of California, in Los Angeles analyzed more than 3.5 million delivery-related hospital admissions from the Nationwide Inpatient Sample (NIS). The system accounts for 20 percent of community hospitals in the United States.

Of those reviewed, 185,514 women acquired diabetes during their pregnancy (gestational diabetes) and nearly one percent had pre-pregnancy diabetes. The researchers identified 563 cases of invasive MRSA among the mothers following delivery – noting the higher risk was associated to mothers with pre-existing diabetes.

Based on the information available, the most frequent sources of infection were skin (30.9 percent), urinary tract (6.4 percent), other genitourinary sites (5.2 percent), wound infections (3 percent) and septicemia (2 percent), reports Medical Xpress.
