Corticosteroid use as adjunct therapy for respiratory syncytial virus infection in adult allogeneic stem cell transplant recipients

BACKGROUND

Respiratory syncytial virus (RSV) infection causes significant morbidity and mortality in allogeneic stem cell transplant (allo-SCT) recipients. Although ribavirin and immunoglobulins are common components of therapy, the role of adjunct corticosteroids is not established.

OBJECTIVES

We sought to evaluate corticosteroid utilization in the setting of post-allo-SCT RSV infection in our center and assess post-transplant outcomes including pulmonary function decline.

METHODS

Patients with a history of RSV infection from 2008 to 2014 seen at our institution were identified. Treatment and outcome data were retrospectively collected. Forced expiratory volume at 1 s (FEV1) and carbon monoxide diffusion capacity (DLCO) were collected pre- and post-RSV infection.

RESULTS

During the observation period, RSV was isolated in 53 of 552 patients undergoing allo-SCT (10%) and 45 had evaluable therapy data. RSV-related mortality in this cohort was 4/45 (9%). Twenty-one (47%) were on corticosteroids prior to RSV diagnosis, of whom 11 (24%) had a dose increase post symptom onset. Eight (18%) patients were started on corticosteroids at the time of RSV infection. Corticosteroid therapy at symptom onset was associated with a higher rate of upper respiratory infection (URTI) to lower respiratory infection (LRTI) progression risk ratio (RR) 2.49 (1.21-5.13; P = 0.016), hospital admission RR 2.05 (1.24-3.37; P = 0.005), or intensive care unit admission RR 2.91 (1.89-5.01; P = 0.002). No significant difference was seen with FEV1 and DLCO decline (P = 0.3 and 0.24, respectively) or mortality (P = 0.26).

CONCLUSION

Adjunct corticosteroid use in the setting of RSV infection did not improve RSV-related outcomes including long-term pulmonary function. Our results do not support the routine use of corticosteroids; however, this finding does need to be verified in a larger cohort of patients.

Temporary pain relief using transcranial electrotherapy stimulation: results of a randomized, double-blind pilot study

Results of a randomized, double-blind pilot study indicate that transcranial electrotherapy stimulation may be an effective treatment for the temporary reduction of pain in osteoarthritis patients. Presently, the predominant method for pain management is medication. One very different approach is the application of micro- to milliamp current applied to specific areas of the head, resulting in a release of endogenous opioids from pain management regions of the brain. For the pilot study, 64 subjects suffering from osteoarthritis of the knee and/or hip were enrolled. For two weeks prior, then during and after treatment, subject pain was self-assessed using the visual scale (VS). In addition, subjects were globally assessed by a physician. All subjects, device operators and physicians were blinded as to whether subjects were treated with an active or sham device. Data collected from the study indicate both a decrease in VS pain scores and a significant improvement (p = 0.05) in physician assessment in subjects treated with active devices compared to those treated with the sham device.
