Switching from onabotulinum toxin A to abobotulinum toxin A for treating detrusor overactivity in spinal cord injured patient, does it really work?

AIM

To assess the efficacy of switching to Abobotulinumtoxin A (ATA) intradetrusor injections (IDI) after failure of Onabotulinumtoxin A (OTA) IDI for the treatment of neurogenic detrusor overactivity in patients with spinal cord injury (SCI).

MATERIALS AND METHODS

A single-centre retrospective chart review study. All SCI patients who started OTA IDI after 2011 and had an ATA IDI switch were included. The primary outcome was the clinical and urodynamic efficacy of the switch to ATA IIDs at the last follow-up. Secondary outcomes were initial efficacy, duration of ATA treatment, and patient outcome including the occurrence of augmentation enterocystoplasty at last follow-up.

RESULTS

Sixty-two patients were included. Eighteen patients (28.9%) were initially responders to ATA IDI. Nine patients (14.5%) remained responders at last follow-up after a median of 17 months (AE 8.8-29). Thirty-two patients (51.6%) had had or were awaiting augmentation enterocystoplasty with a follow-up time of 18.5 months (IQR 8-27). Eleven patients (17.7%) were on ATA IDI with low efficacy. Seven patients (11.3%) were switched back to OTA and 3 patients (4.8%) changed their voiding pattern.

CONCLUSION

Switching from OTA to ATA toxin for IDI in the treatment of detrusor overactivity after spinal cord injury have long-term efficacy for a limited number of patients but may delay the need for surgery.

[Sexual disorders among spinal cord injury patients]

OBJECTIVE

Spinal cord injury (SCI) can alter to varying degrees patients' sexuality. The goals of this study were to evaluate sexual dysfunctions (SD) among a sample of Tunisian patients with SCI and to determine the associated factors.

METHODS

A cross-sectional descriptive study was conducted on a sample of 30 patients with SCI. Sexuality was evaluated by : Male Sexual Quotient (MSQ) and Sexual Health Inventory for Men (SHIM). Other parameters were collected : sociodemographic, clinical, functional capacity, psychological profile and quality of life (QoL) (Short-Form 36 SF36).

RESULTS

The mean age was 41±9.6 years (23-56). The frequency of SD in this study was 69.2 %. The most affected items in the MSQ (76 %) were erection, orgasm, seduction and performance. The SD were associated with alteration of SF36 domains. We noted positive correlations on the one hand between the MSQ score and the role physical (RP) and general health (GH) sub scores of SF36 and on the other hand between the SHIM and the sub scores RP, mental and physical component score (MCS and PCS). The MSQ score was negatively correlated with the HAD score. No other associations were noted.

CONCLUSION

Our study showed a high frequency of SD in SCI patients including Tunisians. SD were mainly associated with impaired QOL and the anxio-depressive profile. The absence of other associations could be explained mainly by the peculiarity of our culture which still considers sexuality and SD as a taboo and secondary subject.

[Antibioprophylaxy and urological management of women with spinal cord injury during pregnancy]

OBJECTIVE

More and more women with spinal cord injury (SCI) can have a pregnancy. Few data have been published on these pregnancies and their urological impact. We report a series of these cases illustrating the urological experience of specialized centers.

METHODS

This is a retrospective study that identified pregnancies in women with SCI followed-up between 2000 and 2014. Data covering all urological and obstetric events during pregnancies, before and after implementation of weekly oral cyclic antibiotics (WOCA) program, were collected from medical records.

RESULTS

Fifteen women with SCI who gave birth to 20 children were included. Three of them were quadriplegics and 12 were paraplegics. All of them performed themselves intermittent catheterization: 11 by urethral way and 4 by high way because carrying a continent cystostomy. Mean follow-up period before pregnancy was 14.6 years [3-27 years IC 95%] and the mean follow-up for the study was 8.5 months [6.5-9 IC 95%]. We observed a reduction of symptomatic urinary tract infections after WOCA onset (13/13 before vs. 0/7 after, P=0.001), a reduction of recurrent urinary infections (6/13 vs. 0/7, P=0.03), a reduction of threats to premature births (8/13 vs. 0/7, P=0.001). Multi-resistant bacteria appeared to increase (0/13 vs. 3/7, P=0.01). We also observed a trend to significant reduction of premature births number (4/13 vs. 0/13, P=0.1) and that of low birth weight (3/13 versus 0/7, P=0.1). The overall neonatal survival rate was 100%.

CONCLUSION

Our study before/after introduction of a weekly oral cycle antibiotic prophylaxis during pregnancy for women with spinal cord injury showed a significant reduction in symptomatic urinary tract infections and a tendency to improve pregnancy outcomes.

Use of psychoactive substances in persons with spinal cord injury: a literature review

OBJECTIVE

To undertake a critical review of literature on use of legal and illegal psychoactive substances (PAS) in persons with spinal cord injury (SCI) before and after trauma.

MATERIAL AND METHODS

Hundred and five articles published between 1980 and 2014 on alcohol and drug use in persons with SCI before and after trauma were retrieved from the PubMed and PsycInfo search engines.

RESULTS

Before injury, 25% to 96% of people with SCI reported using alcohol, while 32% to 35% had used illegal drugs. At the time of injury, 31% to 50% of individuals with SCI were intoxicated with alcohol, 16% to 33% with drugs and 26% with a combination of drugs and alcohol. Among those reporting PAS use before injury, up to 50% stated that they had reduced their use during active rehabilitation, during which time only 6% consumed psychoactive substances for the first time. A variety of risk factors are associated with consumption subsequent to spinal cord injury: personality alteration (impulsiveness, aggressiveness), posttraumatic depression, poor coping skills, lack of social support and pain. PAS use can affect the process of rehabilitation, diminish the effectiveness of medication and result in various medical complications.

DISCUSSION/CONCLUSIONS

Few studies have explored the use of alcohol, drugs and psychoactive medications before SCI and during active rehabilitation. To our knowledge, no study has analyzed the evolution of PAS use after hospital discharge, even though return home is associated with new stressors that may trigger risky behaviors. It should be a priority, as early as possible during rehabilitation, to detect persons at risk of developing PAS abuse.

[Acute decompensation of os odontoideum in the elderly. Case report]

Os odontoideum is a lesion of the second cervical vertebra, usually revealed by a neurological decompensation due to a neck injury in young adults. We report the exceptional case of an os odontoideum decompensation in a 81-year-old patient, who became quadriplegic after a fall. Subsequent surgical treatment resulted in complete neurological recovery. Os odontoideum can decompensate at all ages, and the authors recommend preventive surgical treatment in cases of instability, including in the elderly.
