Antiretroviral treatment can reduce the risk of HIV transmission between male partners to ‘zero’
The risk of transmission of HIV between gay couples when the HIV-positive partner is taking antiretroviral treatment that successfully suppresses the viral load is ‘effectively zero.’
A study of men from 14 European countries, including the UK, found no cases of transmission of HIV from an HIV-positive partner taking antiretroviral therapy to an HIV-negative partner, as long as the viral load of the HIV-positive partner remained undetectable or very low.
The study recorded an avera...
Antimicrobial central venous catheters do not reduce infections in pre-term babies
Central venous catheters (CVCs) impregnated with antimicrobial agents are no better than standard CVCs for avoiding bloodstream infection in pre-term babies.
This NIHR-funded trial compared peripherally inserted CVCs that had been impregnated with a combination of the antifungal miconazole and the broad-spectrum antibiotic rifampicin, against standard non-antimicrobial-impregnated CVCs for preterm babies in intensive care. Rates of bloodstream infections were similar in both groups, and no diff...
Smartphones instead of direct supervision can improve adherence rates for TB treatment
People who need supervision take their medication for tuberculosis (TB) more reliably when using a smartphone to send video evidence instead of direct observations;for example, by attending a clinic appointment. Almost double the number of observations was completed in the video-supervised arm at six months than when people were directly observed.
Ensuring the effectiveness of treatment is central to worldwide TB control. Directly-observed treatment, in which a healthcare professional supervise...
Decision support tools can help GPs reduce antibiotic prescriptions for respiratory conditions
A 12% reduction in GP antibiotic prescriptions for respiratory conditions was achieved through the use of electronic decision and training tools. This reduction did not increase the risk of serious infections compared to usual care.
The low-cost intervention in this large NIHR-funded trial included a short training webinar for GPs and feedback on their practice’s prescribing rates. The decision support tool gave prompt access to NICE prescribing guidelines and printable patient informatio...
Treating asymptomatic MRSA on discharge from hospital reduces risk of later infection
Use of medicated creams, mouthwash and body wash for six months after discharge from hospital led to a 30% lower risk of MRSA infection, compared with basic hygiene education. This study was carried out in the USA using 2,121 adults who had tested positive for MRSA in hospital, but who had no symptoms.
Meticillin-resistant Staphylococcus aureus (MRSA) bacteria have developed resistance to widely-used antibiotics. MRSA is easily transferable within healthcare settings, and people may become colo...
Switching to oral antibiotics early for bone and joint infections gave similar results to continuing intravenous therapy
For adults with bone or joint infection, many of whom had metal implants, beginning six weeks of oral antibiotics within seven days of intravenous treatment, was no worse than a regimen delivered wholly intravenously (IV). After one year, around 14% of both groups still had an infection, showing the difficulty of treatment, irrespective of the route of administration.
Although current practice suggests antibiotics should be given IV for bone and joint infections, for at least six weeks, this la...
Does an antibacterial milk protein reduce infection in premature babies?
Lactoferrin, a protein found in human and cows milk, does not appear to protect premature infants from late-onset infections. When given to babies born before 32 weeks, their risk of acquiring infections, such as sepsis, was virtually the same as those in the control group, about 30%.
Late-onset infections, those occurring 72 hours or more after birth, are a significant cause of illness and even death in newborns. Premature babies are particularly vulnerable. This very large UK based NIHR funde...
C-reactive protein is not useful in diagnosing late-onset infection in newborns
The blood level of C-reactive protein (CRP), a marker indicating inflammation in the body, is not accurate enough alone to diagnose late-onset infection in newborn infants.
Late-onset neonatal infection, occurring more than three days after birth, is potentially serious and is relatively common. Tests measuring the blood level of CRP are widely used by physicians to guide their decision on whether or not to start antibiotic treatment for suspected infection.
This NIHR-funded review found 20 st...
Antimicrobial stewardship programmes reduce antibiotic use in long-term care homes
Antimicrobial stewardship programmes have been found to reduce antibiotic use in long-term care residences by 14% when pooling evidence across a range of study types and interventions.
Antimicrobial resistance is a public health threat, and overuse of antimicrobials is one of the main causes. Antimicrobial stewardship programmes are a government strategy to support the appropriate prescribing of antimicrobials within the NHS. There has been little evidence for their use or effectiveness in lon...
