A history of chronic opioid usage prior to kidney transplantation may be associated with increased mortality risk.

Chronic opioid usage (COU) for analgesia is common among patients with end-stage renal disease. In order to test whether a prior history of COU negatively affects post-kidney transplant outcomes, we retrospectively examined clinical outcomes in adult kidney transplant patients. Among 1064 adult kidney transplant patients, 452 (42.5%) reported the presence of various body pains and 108 (10.2%) reported a prior history of COU. While the overall death or kidney graft loss was not statistically different between patients with and without a history of COU, the cumulative mortality rate at 1, 3, and 5 years after transplantation, and during the entire study period, appeared significantly higher for patients with than without a history of COU (6.5, 18.5, and 20.4 vs. 3.2, 7.5, and 12.7%, respectively). Multivariate Cox regression analysis adjusted for potential confounding factors in entire cohorts and Cox regression analysis in 1:3 propensity-score matched cohorts suggest that a positive history of COU was significantly associated with nearly a 1.6- to 2-fold increase in the risk of death (hazard ratio 1.65, 95% confidence interval 1.04-2.60, and hazard ratio 1.92, 95% confidence interval 1.08-3.42, respectively). Thus, a history of chronic opioid usage prior to transplantation appears to be associated with increased mortality risk. Additional studies are warranted to confirm the observed association and to understand the mechanisms.

Maintenance Electroconvulsive Therapy Is an Essential Medical Treatment for Patients With Catatonia: A COVID-19 Related Experience.

Aim: Describe naturalistic clinical course over 14 weeks in a mixed adolescent and a young-adult patient group diagnosed with developmental delays and catatonia, when the frequency of maintenance electroconvulsive therapy (M-ECT) was reduced secondary to 2020 COVID-19 pandemic restrictions. Methods: Participants were diagnosed with catatonia, and were receiving care in a specialized clinic. They (n = 9), F = 5, and M = 4, ranged in age from 16 to 21 years; ECT frequency was reduced at end of March 2020 due to institutional restrictions. Two parents/caregivers elected to discontinue ECT due to concern for COVID-19 transmission. Majority (n = 8) were developmentally delayed with some degree of intellectual disability (ID). Observable symptoms were rated on a three point scale during virtual visits. Results: All cases experienced clinically significant decline. Worsening of motor symptoms (agitation, aggression, slowness, repetitive self-injury, stereotypies, speech deficits) emerged within the first 3 weeks, persisted over the 14 week observation period and were more frequent than neurovegetative symptoms (appetite, incontinence, sleep). Four participants deteriorated requiring rehospitalization, and 2 among these 4 needed a gastrostomy feeding tube. Conclusion: Moderate and severe symptoms became apparent in all 9 cases during the observation period; medication adjustments were ineffective; resuming M-ECT at each participant's baseline schedule, usually by week 7, resulted in progressive improvement in some cases but the improvement was insufficient to prevent re-hospitalization in 4 cases. In summary, rapid deterioration was noted when M-ECT was acutely reduced in the setting of COVID-19 related restrictions.

Low-dose clonidine in veterans with Posttraumatic stress disorder.

Posttraumatic stress disorder (PTSD) symptoms of hyperarousal are mediated through sympathetic nervous system hyperactivity. PTSD symptoms, including distressing thoughts and memories, flashbacks, hyperarousal, and sleep disturbances, have been linked with elevated norepinephrine levels in the cerebrospinal fluid. Clonidine, an alpha2-adrenergic agonist, reduces the release of norepinephrine and has been suggested as a treatment for PTSD. However, literature for use of clonidine in PTSD is limited. The objective of this study was to evaluate clinical records of patients with PTSD treated with clonidine to assess reported efficacy and safety. A cohort of veterans with PTSD treated with clonidine at a midwestern VA hospital between July 2015 and January 2018 were studied retrospectively. Medical records of 79 patients with moderate to severe PTSD symptoms were reviewed by three independent clinicians using the Clinical Global Impressions (CGI) scale to quantify symptom severity (CGI-S) before starting clonidine and subjects' change in symptoms (CGI-I) after starting clonidine. Data on adverse events were also collected. Subgroup analyses were conducted on the impact of comorbid diagnoses, concurrent medications, and substance use. Mean CGI-S score at baseline was 4.8 (5 = markedly ill). After treatment with low-dose clonidine, 72% of patients experienced improvement, and 49% scored "much improved" or "very much improved." Adverse effects were reported by 18 out of 79 subjects. In this retrospective analysis of veterans prescribed clonidine for PTSD, CGI-I scores suggested improvement in PTSD symptoms, and minimal side effects were reported. In addition, some comorbid diagnoses and concurrent medications were correlated with variations in outcomes.
