However, there is a darker side to anti-amyloid monoclonal antibodies including lecanemab. ARIA, an acronym for amyloid-related imaging abnormalities, have occurred in all trials of anti-amyloid MABs. They occur in two forms, swelling (edema) of the brain (ARIA-E) and microhemorrhages (ARIA-H). Most of the time they are harmless and without symptoms, and they usually resolve within a month or two after stopping the drug. Rarely, they can be severe. As described in a case study, I was one of the subjects in the aducanumab trial who had severe ARIA of both types, swelling and bleeding. I required ICU care for two days, but I eventually fully recovered over the next few months. So far, three research subjects have died during the lecanemab clinical trial.
This chapter puts forward a novel healthcare application of the Trolley Problem by applying it to our most recent global health crisis, the COVID-19 pandemic. The following hypothesis is introduced, analyzed and ultimately rejected: that the Trolley Problem can be used to distinguish between the supposed ethical permissibility of lifting lockdowns and the supposed ethical impermissibility of pursuing herd immunity during the COVID-19 pandemic. The aim of the chapter is twofold: both to test whether and how far we can progress within pandemic ethics by using the Trolley Problem and also to test whether the particular case of the COVID-19 pandemic can make a methodological contribution to trolley debates in philosophy.
Clinical trials are conducted to solve the problem of confounding bias by conducting randomized studies. Examples are given with antidepressants for how clinicians see clinical benefit in practice but randomized clinical trials (RCTs) show that most of the benefit has to do with placebo effects, not the drug pharmacology as clinicians would assume. The conduct of clinical trials is discussed, including the risks of false positive and false negative results depending on how data are analyzed or how sample size is planned. Common errors are identified and criticized.
Despite the acknowledged value of providing prostate radiotherapy patients with sexual dysfunction (SD) information, there is little evidence related to patient perceptions of this or the extent to which information is provided to them. This study aimed to critically evaluate the quality and format of SD information given to patients before, during and after radical EBRT to treat prostate cancer.
Method:
Members of UK prostate cancer support groups were asked to complete an anonymous online survey tool seeking opinions of the SD information they were given before, during and after external beam radiotherapy (EBRT).
Results:
There were 56 responses to the survey with over 42% of respondents reporting that they had not received any SD information. Of those who did, 78·1% (25/32) received information before the start of EBRT. Physicians were the most involved in the provision of SD information, with nurses and therapeutic radiographers being underutilised. Responses were mostly negative, or neutral regarding the quality of SD information and the information received about impact on relationships, psychological and emotional health. Many participants wanted more information and support.
Conclusion:
This study demonstrates that prostate cancer patients who have undergone radical EBRT have not received adequate information relating to potential sexual function side effects and the psychological and emotional effects of SD. This information should be included in verbal and written information provided at all stages of the radiotherapy pathway.
We discuss the case of a 75-year-old man with no psychiatric history, presenting with complex auditory hallucinations, both commentary and imperative, delusions of persecution and prejudice, severe anxiety, modified behaviour, and altered sleep patterns.
Objectives
The patient was started on oral risperidone, with favourable evolution of symptoms after reaching a daily dose of 3 mg/day. After three weeks of treatment, the laboratory results showed a low number of neutrophils. Interdisciplinary approach and examinations which included both clinical and paraclinical evaluation concluded that another cause of neutropenia was highly unlikely.
Methods
The patient was switched to olanzapine, with gradually increasing doses up to 10 mg/day. A significant improvement of the neutrophils’ level was noticed, with a return to normal parameters after a few days. Nevertheless, the clinical course was unfavourable, with reoccurrence of auditory hallucinations and delusions in two weeks’ time. Decision to rechallenge was made, with careful monitoring of the blood test results, particularly neutrophil levels. Risperidone was started at low doses of 0.5 mg/day and gradually increased up to 2 mg/day.
Results
Seven days after risperidone reinitiation laboratory tests showed normal absolute neutrophil count. However, another week later, neutrophils fell again out of the normal range.
Conclusions
The patient was discharged with haloperidol, with adequate control of symptoms and no adverse reactions.
Clozapine is a drug that can cause several side effects. Among the less commonly described is a drug-induced lung disease. Due to its non-specific clinical presentation, it represents a diagnostic challenge. The diagnosis is made based on: 1. Association of exposure to the agent and development of symptoms, 2. Pulmonary infiltration, 3. Exclusion of other causes, 4. Withdrawal of symptoms when the agent is excluded from therapy. To date, there have been only a few descriptions of this condition.
Objectives
Case report of rare side effect of clozapine.
Methods
Case report
Results
Case report: male patient (37) with schizophrenia, was hospitalized after a brutal suicide attempt. The PCR test for COVID-19 that was routinely performed on admission was negative. After the introduction of clozapine into therapy, the patient became febrile. There was a drop in oxygen saturation, a Lung CT scan showed inflammatory changes („ground-glass opacities“), and COVID-19 pneumonia was suspected. Due to the worsening of the mental state, the dose of clozapine was increased. The physical condition further deteriorated: febrile, sO2 declining. After repeated PCR tests for COVID-19 (all negative), interstitial pneumonia caused by clozapine was suspected, and clozapine was excluded from therapy. The physical condition started to improve. Quetiapine was introduced, and occasional episodes of agitation were relieved with intramuscular diazepam. In the following days, the patient’s mental state improved and he was discharged.
Conclusions
Despite its superiority over other antipsychotics, clozapine was with good rationale ranked third in treatment guidelines for schizophrenia.
Serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants thanks to the overall safety and tolerability spectrum. However, they can cause different side effects that not all of them are well identified.
Objectives
We intend to clarify the clinical presentation of mydriasis caused by Escitalopram.
Methods
Reporting the case of a patient suffering a major depressive disorder, that presented a mydriasis after adjusting her antidepressant medication. Then, we conducted a literature review using “PubMed” database and keywords “Mydriasis”, “escitalopram”, “SSRI”,” side effects”.
Results
A 29-year-old female with no past clinical history, presented in May 2021 a severe depression requiring an antidepressant treatment. Under 10 mg per day of escitalopram there was a partial remission of the symptoms, leading to increase the dose by another 10 mg. One month after taking 20 mg/day, she consults before the appointment suffering from a blurry vision and photophobia. Ophthalmologic examination showed a bilateral reactive half-mydriasis, eye pressure was 14 mmHg and fundus examination was normal. Iatrogenic origin of mydriasis was suspected. A gradual interruption of the medication lead to disappearance of the latter. A pharmacological investigation concluded to the suspension of escitalopram and to be vigilant if antidepressant medication would be needed.
Conclusions
Mydriasis is an uncommon side effect caused by SSRI that needs to be kept in mind by clinicians. Therapeutic patient education can help to detect abnormal side effects and treat them if needed.
Polyfarmacy and unjustified use of high dosages of medicaments represent an unmet need in modern psychiatry. Therefore, tidal medication review of hospitalized geriatric patients is an essential step of the disease management as it can be often of vital importance and, as illustrated by current case, can exhibit a tremendeus impact on their quality of life.
Objectives
A case rapport on geriatric patient with iatrogenic damage due to ultra high dosage of ropinirole as a treatment for restless legs syndrome
Methods
Authors of current paper address pharmacodynamic particularities of psychopharmaca and their reasonable choice in context to RLS
Results
A clinical case of a 72 y.o. patient, known with chronic minor depressive symptomes over the past decades. Since few years he did not take any medicaion, except ropinirol for RLS. Because of the worsening of RLS symptomes, he decided on his own to increase the dose of ropinirol up to 12 mg/day. Two moths later he has been admitted to the psychiatric ward with major depression symptomes, suicidal plans, insomnia and profound edema of his both lower legs.
Conclusions
Current case demonstrates that high dose of ropinirole led to tremendous decrease of quality of life of the patient, and pushed him towards concrete suicidal plans. We advocate for careful assessing of the dose of every drug used; avoiding of polypharmacy by any means and for keeping in consideration that the majority of psychopharmaca leads to deterioration of RLS symptoms through modulation of dopamine pathways.
Ischemic colitis is a rare condition. It represents 3 to 10% of lower digestive hemorrhages. It preferentially affects the subject over the age of 50 with predisposing factors. Rare cases have been reported in young subjects with the use of cocaine, combined hormones or antipsychotics.
Objectives
This work aimed to study the potential side effects of antipsychotics
Methods
We report a case of ischemic colitis associated with antipsychotics.
Results
A 27-year-old patient, followed for 2 years for schizophrenia treated with antipsychotics (chlorpromazine and haloperidol) and an antiparkinsonian (Biperiden), consulted in the emergency room for rectorragies progressing for 3 days. The examination revealed the installation of diffuse abdominal pain associated with early postprandial vomiting which preceded the 7-day rectal bleeding. The physical examination revealed ascites without edema of the lower extremities. The stools were normal-colored on digital rectal examination. The biological workup revealed anemia and a biological inflammatory syndrome. The abdomino-pelvic scanner showed thickening of the entire colonic wall with signs of recent bleeding. The rectosigmoidoscopy showed an ecchymotic aspect of the sigmoid with less pronounced involvement of the rectum. Pathologic examination of the colonic biopsies concluded with ischemic colitis, showing hemorrhagic suffisions with numerous fibrinous thrombi of the vessels. The course was marked by the onset of multi-organ failure with acute renal failure, a picture of disseminated intravascular coagulation (DIC) and alveolar hemorrhage. Despite the resuscitation, the patient died 2 days after admission.
Conclusions
Ischemic colitis is a rare side effect of antipsychotics. Although rare, this entity should be evoked and diagnosed in time.
Psychotropic medications are frequently co-prescribed with antiretroviral therapy (ART). Hepatic metabolism both of AP and ART involves the cytochrome P450 enzyme system, potentially leading to a multitude of pharmacokinetic (PK) interactions and serious adverse side effects. The magnitude and clinical impact of PK-interactions can vary significantly.
Objectives
The scope of this review is to summarize the currently available data regarding drug-drug interactions (DDI) between AP and ART, and to provide recommendations for their management.
Methods
A formal search of Embase, Cochrane and Medline was performed, searching for human studies from inception till 2017 on PK-interactions between AP and ART and reporting clinical toxicity as outcomes. Authors also provide their expertise on magnitude and clinical relevance of DDI using PK interaction chart.
Results
Ten case reports including total of 13 patient were analyzed, comprising following AP: aripiprazole (N=2), risperidone (N=4), quetiapine (N=3) and lurasidone (N=1) in combination with various ART regiments. Significant PK-interactions were to occur in cases when aripiprazole was combined with ritonavir and/or cobicistat or efavirenz and/or darunavir; risperidone with indinavir of ritonavir; quetiapine with ritonavir and atazanavir/ritonavir; lurasidone with atazanavir. Adverse events occurred in combinations of aripiprazole with ritonavir/darunavir, risperidone with ritonavir or indinavir, quetiapine with atazanavir and lurasidone with atazanavir.
Conclusions
Psychotropics and antiretrovirals may be used safely, particularly when known DDIs are proactively managed. Clinicians should be aware of the pharmacokinetic and pharmacodynamic properties of these agents to best direct therapy and to provide optimal patient care
We present the case of a 54-year-old man diagnosed with mixed histrionic / obssesive personality disorder admitted in a long-stay hospital. Symptoms began at 40 years of age, predominantly anxiety and agoraphobia alongside somatic complaints. During his admission, the symptoms markedly fluctuated. The patient alternated periods in which he presented confusion with others of irritability, disinhibition, and stereotyped movements. Moreover the patient spent long periods of time in bed with little or no communication with other patients or staff.
The different pharmacological approaches which were carried out and their consequences are analyzed.
Objectives
It is a common practice to increase the number of prescribed drugs or their doses when symptoms worsen. The result is polymedication and higher doses above maximum levels in the technical sheet. Reducing medication is rarely considered as a strategy.
Methods
A case report is presented alongside a review of the relevant literature regarding different long-term pharmacological treatments and their side effects.
Results
The suspension of the antipsychotic treatment which had been administered for years represented a significant improvement. Withdrawal of Olanzapine resulted in a significant improvement.
Conclusions
It is important to review the prescription of each medication in time, as well as to consider their possible side effects.
Attention-deficit/hyperactivity disorder (ADHD) is common in patients with PWS. Symptoms of ADHD are varied and some patients might present with more inattention and less hyperactivity. Poor impulse control (impulsivity) is a component of ADHD that can lead to disruptive behavior such as aggression. Medications are a highly effective means of reducing ADHD symptoms. This chapter describes the phenomenon of ADHD in PWS. In addition, the wide variety of stimulants as well as non-stimulant medicines that are well studied and shown to be effective in the management of ADHD are discussed. Shared decision-making between caregivers and clinicians after reviewing the particular needs of the patient and side-effect profile of ADHD medications is recommended for appropriate treatment. In addition to medications, behavioral therapy is helpful for anxiety, parent–child interaction issues, depression, or oppositional behaviors that may present along with ADHD. Early detection and treatment of ADHD may improve educational outcomes and reduce behavioral problems such as aggression associated with PWS.
The Coronavirus disease 2019 (COVID-19) caused many problems in the health sector. Effective and safe vaccines are the only tool to combat the COVID-19 disease. Researchers and regulatory agencies have made efforts to develop such vaccines and healthcare professionals were prioritized for the vaccination program as first-line care providers. Considering this prioritization, we aimed to assess the physicians’ perceptions regarding the side effects of the COVID-19 vaccine.
Methods:
An interview-based study was conducted from May 5 May to November 5, 2021 (6 months) in a teaching hospital in the capital city of Islamabad, Pakistan.
Results:
Among the 200 physicians who agreed to participate in the interview, 74% were male. A total of 94% did not experience any side effects after receiving the COVID-19 vaccine, regardless of the type of vaccine; 6% experienced side effects. Furthermore, 90% of physicians were afraid of side effects due to the high number of vaccine doses.
Conclusion:
Conclusively, physicians had a positive perception regarding the COVID-19 vaccine. Healthcare authorities and related departments must take precautions to ensure the effective and safe COVID-19 vaccine to change the perceptions of physicians who had a negative perception. This will not only reduce the reluctance among physicians regarding administering COVID-19 vaccine, but will also boost and facilitate the vaccination program for the general public as well.
Automated virtual reality therapies are being developed to increase access to psychological interventions. We assessed the experience with one such therapy of patients diagnosed with psychosis, including satisfaction, side effects, and positive experiences of access to the technology. We tested whether side effects affected therapy.
Methods
In a clinical trial 122 patients diagnosed with psychosis completed baseline measures of psychiatric symptoms, received gameChange VR therapy, and then completed a satisfaction questionnaire, the Oxford-VR Side Effects Checklist, and outcome measures.
Results
79 (65.8%) patients were very satisfied with VR therapy, 37 (30.8%) were mostly satisfied, 3 (2.5%) were indifferent/mildly dissatisfied, and 1 (0.8%) person was quite dissatisfied. The most common side effects were: difficulties concentrating because of thinking about what might be happening in the room (n = 17, 14.2%); lasting headache (n = 10, 8.3%); and the headset causing feelings of panic (n = 9, 7.4%). Side effects formed three factors: difficulties concentrating when wearing a headset, feelings of panic using VR, and worries following VR. The occurrence of side effects was not associated with number of VR sessions, therapy outcomes, or psychiatric symptoms. Difficulties concentrating in VR were associated with slightly lower satisfaction. VR therapy provision and engagement made patients feel: proud (n = 99, 81.8%); valued (n = 97, 80.2%); and optimistic (n = 96, 79.3%).
Conclusions
Patients with psychosis were generally very positive towards the VR therapy, valued having the opportunity to try the technology, and experienced few adverse effects. Side effects did not significantly impact VR therapy. Patient experience of VR is likely to facilitate widespread adoption.
