Status of chloroquine and hydroxychloroquine in COVID-19 infection

COVID-19 causing virus is a single stranded RNA virus which has spread across the globe causing human respiratory tract infection. The novel virus which started from Wuhan was named as Wuhan coronavirus or 2019 novel corona virus (2019-nCov) by the Chinese researchers. The international committee on taxonomy of viruses named the virus as SARS-CoV-2 and the disease as COVID-19. There is preliminary in vitro evidence of the ability of CQ and HCQ to inhibit SARS-CoV-2 activity. Various small group clinical studies conducted in china indicated efficacy of chloroquine and hydroxychloroquine in Covid-19 cases but results were inconclusive. Based on these studies national agencies in various countries issued guidelines mentioning that chloroquine and Hydroxychloroquine are only to be used in clinical trials or emergency use programs. However, USFDA does not recommend use of both these drugs for treatment of COVID-19 cases. Chloroquine and hydroxychloroquine are known to produce dose dependent toxicity including fatal arrhythmias therefore its possible benefit has to be assessed against its risk. Large number of international and national studies are ongoing to assess exact status of chloroquine and hydroxychloroquine for treatment and prophylaxis of COVID-19 infection. Based on these results ICMR recommend to use hydroxychloroquine for prophylaxis of COVID-19 in India and hydroxychloroquine has been is included  in schedule H1 hence they can be sold by pharmaceutical chemists only strictly with a valid prescription and require record to be maintained but chloroquine is still under schedule H which require to be sold with prescription.

incidence Rate of Psychiatric Disorders in 2020: the Pivotal Role Played By Sars-Cov-2 infection

IMPORTANCE: The Coronavirus Disease (COVID-19) pandemic has significantly impacted mental health outcomes. While the frequency of anxiety and depressive symptoms has increased in the whole population, the relationship between COVID-19 and new psychiatric diagnoses remains unclear. OBJECTIVE: to compare the population incidence rate of emergence of de novo psychiatric disorders in 2020 compared to the previous years, and to compare the incidence rate of new psychiatric disorder diagnoses between people with vs without COVID-19. DESIGN, SETTING, AND PARTICIPANTS: This study utilized administrative claims data from the Clinformatics® Data Mart database, licensed from Optum®. The study is a cross-sectional analysis that compared the incidence rate of new psychiatric disorders in 2020 vs. 2018 and 2019 in the entire insured population database. Subsequently, the incidence of new psychiatric disorders in people with vs. without COVID-19 during 2020 was analyzed. EXPOSURE: The exposures included diagnosis and severity of COVID-19 infection. MAIN OUTCOMES MEASURES: The dependent variables of interest were the incidence rates of new psychiatric disorders, specifically schizophrenia spectrum disorders, mood disorders, anxiety disorders, and obsessive-compulsive disorder. RESULTS: The population studied included 10,463,672 US adults (mean age 52.83, 52% female) who were unique people for the year of 2020. Incidence of newly diagnosed psychiatric disorders per 1,000 individuals in the 2020 whole population were 28.81 (CI: 28.71, 28.92) for anxiety disorders, 1.04 (CI: 1.02, 1.06) for schizophrenia disorders, 0.42 (CI: 0.41, 0.43) for OCD and 28.85 (CI: 28.75, 28.95) for mood disorders. These rates were not significantly higher than 2018 or 2019. When comparing incidence rates between COVID-19 vs. non-COVID-19 populations in 2020, the rates were significantly higher in the COVID-19 population: 46.89 (CI: 46.24, 47.53) for anxiety, 49.31 (CI: 48.66, 49.97) for mood disorders, 0.57 (CI: 0.50, 0.65) for OCD, and 3.52 (CI: 3.34, 3.70) for schizophrenia. COVID-19 severity was significantly associated with new diagnoses of schizophrenia, anxiety and mood disorders in multivariate analyses. CONCLUSIONS: Compared to 2018 and 2019, in 2020 there was no increased incidence of new psychiatric disorders in the general population based on insurance claims data. Importantly, people with COVID-19 were more likely to be diagnosed with a new psychiatric disorder, most notably disorders with psychosis, indicating a potential association between COVID-19 and mental/brain health

Understanding causes of hospitalization and access to care among newly diagnosed HIV patients in Houston, TX

More than a quarter of patients with HIV in the United States are diagnosed in hospital settings most often with advanced HIV related conditions.(1) There has been little research done on the causes of hospitalization when the patients are first diagnosed with HIV. The aim of this study was to determine if the patients are hospitalized due to an HIV related cause or due to some other co-morbidity. Reduced access to care could be one possible reason why patients are diagnosed late in the course of the disease. This study compared the access to care of patients diagnosed with HIV in hospital and outpatient setting. The data used for the study was a part of the ongoing study “Attitudes and Beliefs and Steps of HIV Care”. The participants in the study were newly diagnosed with HIV and recruited from both inpatient and outpatient settings. The primary and the secondary diagnoses from hospital discharge reports were extracted and a primary reason for hospitalization was ascertained. These were classified as HIV-related, other infectious causes, non–infectious causes, other systemic causes, and miscellaneous causes. Access to care was determined by a score based on responses to a set of questions derived from the HIV Cost and Services Utilization Study (HCSUS) on a 6 point scale. The mean score of the hospitalized patients and mean score of the patients diagnosed in an outpatient setting was compared. We used multiple linear regressions to compare mean differences in the two groups after adjusting for age, sex, race, household income educational level and health insurance at the time of diagnosis. There were 185 participants in the study, including 78 who were diagnosed in hospital settings and 107 who were diagnosed in outpatient settings. We found that HIV-related conditions were the leading cause of hospitalization, accounting for 60% of admissions, followed by non-infectious causes (20%) and then other infectious causes (17%). The inpatient diagnosed group did not have greater perceived access-to-care as compared to the outpatient group. Regression analysis demonstrated a statistically significant improvement in access-to-care with advancing education level (p=0.04) and with better health insurance (p=0.004). HIV-related causes account for many hospitalizations when patients are first diagnosed with HIV. Many of these HIV-related hospitalizations could have been prevented if patients were diagnosed early and linked to medical care. Programs to increase HIV awareness need to be an integral part of activities aimed at control of spread of HIV in the community. Routine testing for HIV infection to promote early HIV diagnosis can prevent significant morbidity and mortality

Residuals in post-chemotherapy, non-depressed patients with leukemia that is in remission

Debate persists regarding the occurrence and etiology of neurocognitive deficits associated with the utilization of chemotherapeutic agents, commonly referred to as “chemobrain”. While some have previously attributed these features to other factors such as fatigue, emotional reactivity, etc., growing literature suggests that in fact chemotherapeutic agents may be the cause. Although research has investigated these deficits, greater investigation is warranted. The current study investigated the presence of residual neurocognitive deficits in non-depressed patients post-chemotherapy with a history of leukemia that was in remission in comparison to healthy controls. Methods: participants included 16 individuals with a history of leukemia post-chemotherapy, in remission and without depression and 48 healthy controls. Participants were assessed using the WJ-III with data from the first seven subtests entered for analysis. A multivariate analysis of variance revealed significant differences existed between groups. By way of a discriminant function analysis, subtest/domain specific discrepancies were noted. Specifically, participants with a history of leukemia who were post-chemotherapy and without depression were found to perform significantly worse on visual-auditory learning, concept formations, and sound blending than did healthy controls. Findings are seen as additional support of the idea that neurocognitive deficits do in fact occur following chemotherapy. However, they are particularly of interest as they are seen even in the absence of emotional distress and outside the active treatment phase. Additional findings of importance and clinical relevance will be discussed

Retrospective examination of cannabis vs. other substance misuse: Associations with 30-day readmission and global assessment of functioning in hospitalized patients with serious mental illness

Substance misuse in individuals with psychiatric disorders is associated with worsening symptoms and hospitalization. The present retrospective, observational study analyzed inpatient psychiatry hospital EHR data from 2013 to 2020 (N = 12,742) in patients with co-occurring psychiatric disorders and substance misuse. Substance use was categorized as cannabis-only, alcohol-only, or illicit/poly-substance. Two outcome variables were evaluated using multiple-regression: (1) Global Assessment of Functioning (GAF) Score at admission, and (2) 30-day readmission rate. Covariates included primary Axis I disorder, living situation, Race/Ethnicity, education, sex, age, and total same-hospital readmissions (>30 days). Controlling for all covariates, the cannabis-only group had (1) significantly higher GAF score at admission (less severity) vs. both other groups; and (2) lower 30-day readmission rates vs. the illicit/poly-substance use group only. Post-hoc analyses revealed the results for the cannabis-only group vs. other drug use groups were robust, holding across all primary psychiatric diagnoses. Study limitations included lack of formal SUD diagnosis, lack of information in the EHR to quantify substance use patterns, retrospective study design, and lack of data to examine an appropriate psychiatric inpatient group free of substance misuse. Results are discussed in terms of the putative therapeutic efficacy of THC and cannabidiol on modulation of sleep, anxiety, and agitation

Pharmacogenomics of Lithium Response in Bipolar Disorder

Despite being the most widely studied mood stabilizer, researchers have not confirmed a mechanism for lithium’s therapeutic efficacy in Bipolar Disorder (BD). Pharmacogenomic applications may be clinically useful in the future for identifying lithium-responsive patients and facilitating personalized treatment. Six genome-wide association studies (GWAS) reviewed here present evidence of genetic variations related to lithium responsivity and side effect expression. Variants were found on genes regulating the glutamate system, including GAD-like gene 1 (GADL1) and GRIA2 gene, a mutually-regulated target of lithium. In addition, single nucleotide polymorphisms (SNPs) discovered on SESTD1 may account for lithium’s exceptional ability to permeate cell membranes and mediate autoimmune and renal effects. Studies also corroborated the importance of epigenetics and stress regulation on lithium response, finding variants on long, non-coding RNA genes and associations between response and genetic loading for psychiatric comorbidities. Overall, the precision medicine model of stratifying patients based on phenotype seems to derive genotypic support of a separate clinical subtype of lithium-responsive BD. Results have yet to be expounded upon and should therefore be interpreted with caution

Evaluating the Efficacy of Automated Smoking Treatment for People With HIV: Protocol for a Randomized Controlled Trial

BackgroundSmoking prevalence rates among people with HIV are nearly 3 times higher than those in the general population. Nevertheless, few smoking cessation trials targeting smokers with HIV have been reported in the literature. Efforts to develop and evaluate sustainable, low-cost, and evidence-based cessation interventions for people with HIV are needed. Given the widespread proliferation of mobile phones, the potential of using mobile health apps to improve the reach and efficacy of cessation interventions is promising, but evidence of efficacy is lacking, particularly among people with HIV. ObjectiveThis study will consist of a 2-group randomized controlled trial to evaluate a fully automated smartphone intervention for people with HIV seeking cessation treatment. MethodsParticipants (N=500) will be randomized to receive either standard treatment (ST; 250/500, 50%) or automated treatment (AT; 250/500, 50%). ST participants will be connected to the Florida Quitline and will receive nicotine replacement therapy in the form of transdermal patches and lozenges. This approach, referred to as Ask Advise Connect, was developed by our team and has been implemented in numerous health systems. ST will be compared with AT, a fully automated behavioral treatment approach. AT participants will receive nicotine replacement therapy and an interactive smartphone-based intervention that comprises individually tailored audiovisual and text content. The major goal is to determine whether AT performs better in terms of facilitating long-term smoking abstinence than the more resource-intensive ST approach. Our primary aim is to evaluate the efficacy of AT in facilitating smoking cessation among people with HIV. As a secondary aim, we will explore potential mediators and moderators and conduct economic evaluations to assess the cost and cost-effectiveness of AT compared with ST. ResultsThe intervention content has been developed and finalized. Recruitment and enrollment will begin in the fall of 2021. ConclusionsThere is a critical need for efficacious, cost-effective, and sustainable cessation treatments for people with HIV who smoke. The AT intervention was designed to help fill this need. If efficacy is established, the AT approach will be readily adoptable by HIV clinics and community-based organizations, and it will offer an efficient way to allocate limited public health resources to tobacco control interventions.
