Abstract

These clinical practice guidelines are an update of the guidelines published by the Infectious Diseases Society of America (IDSA) in 2009, prior to the 2009 H1N1 influenza pandemic. This document addresses new information regarding diagnostic testing, treatment and chemoprophylaxis with antiviral medications, and issues related to institutional outbreak management for seasonal influenza. It is intended for use by primary care clinicians, obstetricians, emergency medicine providers, hospitalists, laboratorians, and infectious disease specialists, as well as other clinicians managing patients with suspected or laboratory-confirmed influenza. The guidelines consider the care of children and adults, including special populations such as pregnant and postpartum women and immunocompromised patients.

Hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS) are transmitted to humans through infection with the old- and new-world hantaviruses, respectively.

Together these diseases affect tens of thousands of people every year, and no specific treatment is available.

To investigate whether ribavirin treatment for hantaviruses infections decreases disease severity, we conducted a meta-analysis involving human and animal studies.

After defining the research protocol and criteria for inclusion/exclusion, we identified seven studies. We found that in groups with HPS who were treated with ribavirin, there was no significant reduction in mortality (RR 0.99, 95 % CI 0.60–1.61, I2 = 0 %).

On the other hand, for animal group with HPS-like disease, there was significant increase in survival (RR 0.05, 95 % CI 0.01–0.34, I2 = 0 %).

For animal group infected with the old-world hantaviruses, treated with ribavirin, there was a statistically significant increase in survival (RR 0.56, 95 % CI 0.42–0.76, I2 = 64 %).

Similarly, for humans with HFRS treated, there was increase in survival (RR 0.28, 95 % CI 0.08–1), although only a study exist.

Our meta-analysis provides data that should be interpreted with caution, partly due to the limited number of studies available.

Additionally, the results of the application of ribavirin in the population with HPS could not be determined, particularly in patients in the end stage of this disease.

Infections in patients affected by rheumatologic diseases associated to glucocorticoid use or tumor necrosis factor-alpha inhibitors.

Rev Chilena Infectol. April 2014 V.31 N.2 P.181-95.

[Article in Spanish]

Fica A.

Abstract

A great diversity of infectious agents can affect patients that use steroids at immunosuppressive doses or tumor necrosis factor alpha (TNF-alpha) antagonists.

The list of participating microorganisms is more restricted in the case of anti TNF-alpha blockers.

Overlapping agents include intracellular bacteria, Mycobacterium tuberculosis, geographic fungal agents that have the ability to establish granulamotous infections, herpes zoster, and reactivation of chronic hepatitis B virus infection.

An important conceptual issue for these infections is the existence of a threshold prednisone daily dose for the emergence of opportunistic infections but higher levels of immunosuppression and cofactors are required in the case of Pneumocystis jiroveci and cytomegalovirus infections.

In order to prevent these threats, a detailed medical evaluation is needed before prescription to detect potential risks and manage them properly.

Prevention rules must be prescribed in every case, that include common sense behaviors, vaccines, and in selected cases, chemoprophylaxis for latent tuberculosis (TB) infection, P. jiroveci pneumonia (PCP) or other specific requirements.

Latent TB infection is probable and requires chemoprophylaxis in the case of remote or recent exposure to a patient with lung TB, a positive tuberculin or interferon-gamma release assay result or residual lung scars in a chest x-ray exam.

PCP prevention is suggested when the patient reaches a daily dose of prednisone of 30 mg but might be needed at lower doses in case of other concomitant immunosuppressive drugs or when lymphopenia arises shortly after prednisone initiation.

Statin use and the risk of herpes zoster: a nested case-control study using primary care data from the U.K. Clinical Research Practice Datalink.

Br J Dermatol. December 2016 V.175 N.6 P.1183-1194.

Abstract

BACKGROUND:

Statins are commonly prescribed worldwide and recent evidence suggests that they may increase the risk of herpes zoster (HZ).

OBJECTIVES:

To quantify the effect of statin exposure on the risk of HZ in the U.K.

METHODS:

A matched case-control study was conducted using data from U.K. primary care and hospital records. Patients > 18 years with an incident diagnosis of HZ were matched to up to four controls for age, sex and general practice. Patients were included in the statin exposure group if they had ever used a statin, and the daily dosage of the most recent statin prescription and the time since the most recent statin prescription were also recorded. The primary outcome was an incident diagnosis of HZ. Odds ratios (ORs) were estimated from conditional logistic regression and adjusted for potential confounders.

RESULTS:

A total of 144 959 incident cases of HZ were matched to 549 336 controls. Adjusted analysis suggested strong evidence for an increase in the risk of HZ related to statin exposure (OR 1·13, 95% confidence interval 1·11-1·15). There was also an increased risk when dosages were increased for patients who were currently or had recently been receiving statin treatment (Ptrend < 0·001), and we found an attenuation of the increased risk of HZ in previous statin users as the time since last statin exposure increased (Ptrend < 0·001).

CONCLUSIONS:

These findings are consistent with the hypothesis that statin therapy leads to an increase in the risk of HZ.

Herpes zoster is associated with prior statin use: a population-based case-control study.

PLoS One. October 24, 2014 V.9 N.10 P.:e111268.

Abstract

BACKGROUND:

This study investigated the association between statin use and herpes zoster (HZ) occurrence in a population-based case-control study.

METHODS:

Study subjects were retrieved from the Taiwan Longitudinal Health Insurance Database 2000. This study included 47,359 cases with HZ and 142,077 controls. We performed conditional logistic regression analyses to calculate the odds ratio (OR) to present the association between HZ and having previously been prescribed statin.

RESULTS:

We found that 13.0% of the sampled subjects had used statins, at 15.5% and 12.1% for cases and controls, respectively (p<0.001). A conditional logistic regression analysis suggested that the adjusted OR of being a statin user before the index date for cases was 1.28 (95% confidence interval (CI): 1.24∼1.32) compared to controls. Subjects aged 18∼44 years had the highest adjusted OR for prior statin use among cases compared to controls (OR: 1.69; 95% CI: 1.45∼1.92). Furthermore, we found that the ORs of being a regular and irregular statin user before the index date for cases were 1.32 (95% CI: 1.27∼1.38) and 1.23 (95% CI: 1.181.29), respectively, compared to controls.

CONCLUSIONS:

We concluded that prior statin use was associated with HZ occurrence.
