FDA warns of potential contamination in multiple brands of drugs, dietary supplements
The U.S. Food and Drug Administration is advising consumers and health care professionals not to use any liquid drug or dietary supplement products manufactured by PharmaTech LLC of Davie, Florida, and labeled by Rugby Laboratories, Major Pharmaceuticals and Leader Brands, due to potential contamination with the bacteria Burkholderia cepacia (B. cepacia) and the risk for severe patient infection.

Abstract Chlorhexidine gluconate (CHX) and benzalkonium chloride (BZK) formulations are frequently used as antiseptics in healthcare and consumer products. Burkholderia cepacia complex (BCC) contamination of pharmaceutical products could be due to the use of contaminated water in the manufacturing process, over-diluted antiseptic solutions in the product, and the use of outdated products, which in turn, reduces the antimicrobial activity of CHX and BZK. To establish a "safe use" period following opening containers of CHX and BZK, we measured the antimicrobial effects of CHX (2 ~ 10 µg/ml) and BZK (...

Bhanage Kinetic resolution of rac-1,2-diols using the biocatalyst Burkholderia cepacia lipase (BCL) immobilized on a biodegradable binary blend support of hydroxypropyl methyl cellulose(HPMC)/polyvinyl alcohol (PVA) has been investigated. The immobilization technique improved enzyme activity significantly and it has excellent recyclability with good yield and enantiomeric excess values up to the studied range of nine cycles. At optimum reaction conditions, conversion of 45–50...
AbstractTheBurkholderia cepacia complex (BCC) can cause a severe decline in lung function in cystic fibrosis (CF). Our objective was to determine the BCC prevalence and to evaluate its clinical impact on CF. Clinical and laboratory variables were determined for CF patients with BCC (Group-A = 50 patients) and without BCC (Group-B = 134 patients). The microorganisms were identified by biochemical tests, the Vitek2®Compact test,recA-PCR andrecA-nested-PCR with species-specific primers and DNA sequencing. The patients were evaluated by the Shwachman –Kulczycki score (SKCS), Bhalla score (BS), sp...

Conclusions The pseudobacteraemia cases were caused by contaminated 0.5% CHG from a single company. Stricter government regulation is needed to prevent contamination of disinfectants during manufacturing. In addition, microbial contamination of antiseptics and disinfectants should be suspected when a B. cepacia outbreak occurs in hospitalised patients.
Conclusions Ongoing surveillance and prompt investigation of unusual disease outbreaks are vital for identifying sources of contamination of B. cepacia and protecting at-risk patients. Sound epidemiological methods are very important for identifying the source of any hospital infection outbreak.
