US commission faults Indian hospital's alleged religious segregation of coronavirus patients

CNA Staff, Apr 17, 2020 / 07:00 pm (CNA).- Reports of an Indian hospital's segregated wards for Hindu and Muslim coronavirus patients drew concern from the U.S. Commission on International Religious Freedom, though Indian authorities strongly disputed the allegation.

"USCIRF is concerned with reports of Hindu and Muslim patients separated into separate hospital wards in Gujarat,” the commission said on Twitter and Facebook April 15. “Such actions only help to further increase ongoing stigmatization of Muslims in India and exacerbate false rumors of Muslims spreading COVID-19.”

The bipartisan U.S. federal government commission linked to a story in the Indian Express newspaper that cites a hospital official and a patient in the city of Ahmedabad in the western coastal Indian state of Gujarat.

India's Ministry for External Affairs opposed the commission, saying it was spreading “misguided reports” and “adding religious color” that distracts from India's efforts to combat the novel coronavirus.

“No segregation is being done in civil hospitals on the basis of religion, as clarified by the Gujarat government,” the ministry said April 15.

The reports concern Ahmedabad Civil Hospital, where there are some 1,200 beds prepared for patients suffering from the novel coronavirus.

Medical Superintendent Dr. Gunvant. H. Rathod described the hospital division to the Indian Express, saying “generally, there are separate wards for male and female patients. But here, we have made separate wards for Hindu and Muslim patients.”

“It is a decision of the government and you can ask them,” he said.

Deputy Chief Minister and Health Minister Nitin Patel said he was not aware of the situation and would make inquiries. Ahmedabad's district magistrate, K.K. Nirala, also was not aware of any decision, the Indian Express reports.

However, the Indian Express cited a hospital patient who said the names of 28 men in a ward were called out, and they were moved to another ward.

“While we were not told why we were being shifted, all the names that were called out belonged to one community. We spoke to one staff member in our ward today and he said this had been done for ‘the comfort of both communities’,” the patient said.

The Gujarat Health and Family Welfare Department said the reports were “absolutely baseless.” Rather, it said, patients are treated based on symptoms and severity and “according to treating doctors' recommendations.

As of Wednesday, new known cases of coronavirus in Gujarat rose by 127 to 766, with 88 cases in Ahmedabad. The death toll there totals 33, the Times of India reports.

The Indian newspaper The Week reported that the commission had previously criticized India's Citizenship Amendment Act, which became effective in January 2020.

In December 2019 the commission expressed concern about the legislation, which enshrined a pathway to citizenship for immigrants but specifically excluded Muslims. The commission recommended U.S. sanctions on India as a possible response.

The U.S. Commission on Religious Freedom reviews alleged religious freedom violations and makes policy recommendations to the U.S. president, Secretary of State, and Congress.

The commission’s 2019 report said that religious freedom conditions in India “continued a downward trend” in 2018. It said India’s “history of religious freedom has come under attack in recent years with the growth of exclusionary extremist narratives—including, at times, the government’s allowance and encouragement of mob violence against religious minorities—that have facilitated an egregious and ongoing campaign of violence, intimidation, and harassment against non-Hindu and lower-caste Hindu minorities. Both public and private actors have engaged in this campaign.”

Mob violence against Christians by Hindus has been particularly acute.

In August 2019, six suspected members of a radical Hindu group were arrested after dozens of Catholics were attacked on a Marian pilgrimage from Karnataka to the Basilica of Our Lady of Good Health in Velankanni, a coastal town in south east India.

In September, around 500 armed Hindu extremists attacked a Jesuit mission in the Archdiocese of Ranchi. Armed with sticks, chains, iron bars, knives, and pistols, the mob beat tribal students including two who were seriously injured, and also seriously damaged the school’s facilities.

Archbishop Leo Cornelio of Bhopal has said numerous mob lynchings of Christians have occurred in which the victims are accused of eating beef or otherwise harming cattle, which are considered sacred in Hinduism.

Karnataka state suffered a wave of anti-Christian violence in 2008, when Hindu extremist groups led attacks on churches, schools and homes of Christians and physically beat hundreds of people. A 2011 independent report on the violence, known as the Saldhana Report, charged that attacks were pre-planned and backed by the state’s highest government authorities.

Agitation in Patients With Autism Spectrum Disorder Admitted to Inpatient Pediatric Medical Units

OBJECTIVES:

Our goals for this study were to characterize the frequency of agitation in patients with autism spectrum disorder (ASD) admitted to an inpatient pediatric medical unit and to identify risk factors associated with agitation.

METHODS:

Through a retrospective chart review, we identified every patient between 8 and 19 years of age with a documented ASD diagnosis admitted to a pediatric medical unit over a 5-year period. We performed a detailed review of each admission, with a focus on factors hypothesized to be correlated with risk of agitation.

RESULTS:

One or more episode of agitation occurred during 37 (12.4%) of the 299 admissions and for 31 (18.5%) of the 168 patients who met inclusion criteria. History of agitation (risk ratio 21.9 [95% confidence interval 5.4–88.3] for history of severe agitation; P < .001) and documented sensory sensitivities (risk ratio 2.3 [95% confidence interval 1.3–3.8]; P < .001) were associated with a significantly increased risk of agitation during admission. History of past psychiatric admissions was associated with increased risk before, but not after, controlling for history of agitation and sensory sensitivities. Psychiatric comorbidity, intellectual disability, acute pain on admission, number of preadmission psychotropic medications, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition ASD diagnosis, age, and sex were not significantly associated with increased risk.

CONCLUSIONS:

Hospitalization can be challenging for patients with ASD. A subset of these patients experience episodes of agitation during admission, posing a safety risk to patients and staff. Characterizing risk factors associated with these behaviors may allow for identification of at-risk patients and guide targeted intervention to prevent negative behavioral outcomes.

Significant efficacy of single low dose primaquine compared to stand alone artemisinin combination therapy in reducing gametocyte carriage in Cambodian patients with uncomplicated multidrug resistant Plasmodium falciparum malaria [Epidemiology and Surveil

Since 2012, single low dose of primaquine (SLDPQ, 0.25mg/kg) has been recommended with artemisinin-based combination therapies, as first-line treatment of acute uncomplicated Plasmodium falciparum malaria, to interrupt its transmission, especially in low transmission settings of multidrug, including artemisinin, resistance. Policy makers in Cambodia have been reluctant to implement this recommendation due to primaquine safety concerns and lack of data on its efficacy.

In this randomized controlled trial, 109 Cambodians with acute uncomplicated P. falciparum malaria received dihydroartemisinin-piperaquine (DP) alone or combined with SLDPQ on the first treatment day. Transmission-blocking efficacy of SLDPQ was evaluated on Days 0, 1, 2, 3, 7, 14, 21, 28 and recrudescence by reverse transcriptase polymerase chain reaction (RT-PCR) (gametocyte prevalence) and membrane-feeding assays with Anopheles minimus mosquitoes (gametocyte infectivity). Without the influence of recrudescent infections, DP+SLDPQ reduced gametocyte carriage 3 fold compared to DP. Of 48 patients tested on Day 0, only three patients were infectious to mosquitoes (~6%). Post-treatment, three patients were infectious: on D14 (3.5%, 1/29), and on the first and seventh day of recrudescence (8.3%, 1/12 for each); this overall low infectivity precluded our ability to assess its transmission blocking efficacy.

Our study confirms effective gametocyte clearance of SLDPQ when combined with DP in multidrug resistant P. falciparum and the negative impact of recrudescent infections due to poor DP efficacy. Artesunate-mefloquine (ASMQ) has replaced DP and ASMQ-SLDPQ has been deployed to treat all P. falciparum symptomatic patients to further support the elimination of multidrug resistant P. falciparum in Cambodia.

A Comparison of Clinical Outcomes among Intensive Care Unit Patients Receiving Ceftriaxone 1 gram daily or 2 grams daily [Clinical Therapeutics]

Background: Intensive care unit (ICU) patients may experience ceftriaxone underexposure but clinical outcomes data are lacking. The objective of this study was to determine the impact of ceftriaxone dosing on clinical outcomes amongst ICU patients without central nervous system (CNS) infection.

Methods: A retrospective study of ICU patients receiving intravenous, empiric ceftriaxone for non-CNS infections was conducted. Patients ≥18 years of age who received ≤2 grams of ceftriaxone daily for ≥72 hours were included and categorized as receiving ceftriaxone 1 gram or 2 grams daily. The primary, composite outcome was treatment failure: inpatient mortality and/or antibiotic escalation due to clinical worsening. Propensity score matching was performed based on the probability of receiving ceftriaxone 2 grams daily. Multivariable logistic regression determined the association between ceftriaxone dose and treatment failure in a propensity-matched cohort.

Results: A total of 212 patients were included in the propensity-matched cohort. The most common diagnoses (83.0%) were pneumonia and urinary tract infection. Treatment failure occurred in 17.0% and 5.7% of patients receiving 1 gram and 2 grams daily, respectively (p=0.0156). Overall inpatient mortality was 8.5%. Ceftriaxone 2 gram dosing was associated with a reduced likelihood of treatment failure (adjusted odds ratio=0.190; 95% confidence interval: 0.059 – 0.607). Other independent predictors of treatment failure included sequential organ failure assessment score (aOR 1.440, 95% CI 1.254 – 1.653) and creatinine clearance at 72 hours from ceftriaxone initiation (aOR 0.980, 95% CI (0.971 – 0.999).

Conclusions: Ceftriaxone 2 grams daily when used as appropriate antimicrobial coverage may be appropriate for ICU patients with lower mortality risk.

Population Pharmacokinetics and Dosage Optimization of Linezolid in Patients with Liver Dysfunction [Pharmacology]

Linezolid is the first synthetic oxazolidone agent to treat infections caused by Gram-positive pathogens. Infected patients with liver dysfunction (LD) are more likely to suffer from adverse reactions such as thrombocytopenia when standard-dose linezolid is used than patients with LD who didn't use linezolid. Currently, pharmacokinetics data of linezolid in patients with LD are limited. The study aimed to characterize pharmacokinetics parameters of linezolid in patients with LD, identify the factors influencing the pharmacokinetics, and propose an optimal dosage regimen. We conducted a prospective study and established population pharmacokinetics model with the Phoenix NLME. The final model was evaluated by goodness-of-fit plots, bootstrap analysis, and prediction corrected-visual predictive check. A total of 163 concentration samples from 45 patients with LD were adequately described by a one-compartment model with first-order elimination along with prothrombin activity (PTA) and creatinine clearance as significant covariates. Linezolid clearance (CL) was 2.68 L/h (95% confidence interval [CI]: 2.34-3.03 L/h); the volume of distribution (Vd) was 58.34 L (95% CI: 48.00-68.68 L). Model-based simulation indicated that the conventional dose was at risk for overexposure in patients with LD or severe renal dysfunction; reduced dosage (300 mg/12 h) would be appropriate to achieve safe (Cmin, ss at 2-8 ug/mL) and effective targets (the ratio of AUC0-24 at steady state to MIC, 80-100). In addition, for patients with severe LD (PTA <= 20%), the dosage (400 mg/24 h) was sufficient at an MIC <= 2 ug/mL. This study recommended therapeutic drug monitoring for patients with LD.

Imipenem population pharmacokinetics: therapeutic drug monitoring data collected in critically ill patients with or without extracorporeal membrane oxygenation [Pharmacology]

Carbapenem pharmacokinetic profiles are significantly changed in critically ill patients because of the drastic variability of the patients' physiological parameters. Published population PK studies have mainly focused on specific diseases and the majority of these studies had small sample sizes. The aim of this study was to develop a population PK model of imipenem in critically ill patients that estimated the influence of various clinical and biological covariates and the use of Extracorporeal Membrane Oxygenation (ECMO) and Continuous Renal Replacement Therapy (CRRT). A two-compartment population PK model with Creatinine clearance (CrCL), body weight (WT), and ECMO as fixed effects was developed using the non-linear mixed effect model (NONMEM). A Monte Carlo simulation was performed to evaluate various dosing schemes and different levels of covariates based on the pharmacokinetic/pharmacodynamic index (f%T>MIC) for the range of clinically relevant minimum inhibitory concentrations(MICs). The results showed that there may be insufficient drug use in the clinical routine drug dose regimen, and 750mg Q6h could achieve a higher treatment success rate. The blood concentrations of imipenem in ECMO patients were lower than that of non-ECMO patients, therefore dosage may need to be increased. The dosage may need adjustment for patients with CrCL ≤ 70ml/min, but dose should be lowered carefully to avoid the insufficient drug exposure. Dose adjustment is not necessary for patients within the WT ranging from 50-80 kg. Due to the large variation in PK profile of imipenem in critically ill patients, TDM should be carried out to optimize drug regimens.

Population pharmacokinetics of piperacillin following continuous infusion in critically ill patients: Impact of renal function on target attainment [Clinical Therapeutics]

Pharmacokinetic changes are often seen in patients with severe infections. Administration by continuous infusion has been suggested to optimize antibiotic exposure and pharmacokinetic/pharmacodynamic (PK/PD) target attainment for β-lactams. In an observational study, unbound piperacillin concentrations (n=196) were assessed in 78 critically ill patients following continuous infusion of piperacillin/tazobactam (ratio 8:1). The initial dose of 8, 12 or 16 g (piperacillin component) was determined by individual creatinine clearance (CRCL). Piperacillin concentrations were compared to the EUCAST clinical breakpoint MIC for Pseudomonas aeruginosa (16 mg/L), and the following PK/PD targets were evaluated: 100% fT>1xMIC and 100% fT>4xMIC. A population pharmacokinetic model was developed using NONMEM 7.4.3 consisting of a one-compartment disposition model with linear elimination separated into non-renal and renal (linearly increasing with patient CRCL) clearances. Target attainment was predicted and visualized for all individuals based on the utilized CRCL dosing algorithm. The target of 100% fT>1xMIC was achieved for all patients based on the administered dose, but few patients achieved the target of 100% fT>4xMIC. Probability of target attainment for a simulated cohort of patients showed, that increasing the daily dose by 4 g increments (piperacillin component) did not result in substantially improved target attainment for the 100% fT>4xMIC target. To conclude, in patients with high CRCL combined with high-MIC bacterial infections, even a CI regimen with a daily dose of 24 g may be insufficient to achieve therapeutic concentrations.

Epidemiological study on prevalence, serovar diversity, multi-drug resistance and CTX-M-type extended-spectrum {beta}-lactamases of Salmonella spp. from patients with diarrhea, food of animal origin, and pets in several provinces of China [Epidemiology an

A total of 2,283 Salmonella spp. isolates were recovered from 18,334 samples including patients with diarrhea, food of animal origin and pets across 5 provinces of China. The highest prevalence of Salmonella spp. was detected in chicken meats (39.3%, 486/1,237). Fifteen serogroups and 66 serovars were identified, with Typhimurium and Enteritidis being the most dominant. Most (85.5%, 1,952/2,283) isolates exhibited resistant to ≥ 1 antimicrobial and 56.4% were multi-drug resistant (MDR). A total of 222 isolates harbored extended-spectrum β-lactamases (ESBLs), 200 of which were CTX-M-type that were mostly detected from chicken meat and turtle fecal. Overall, eight blaCTX-M genes were identified, with blaCTX-M-65, blaCTX-M-123, blaCTX-M-14, blaCTX-M-79, and blaCTX-M-130 being the most prevalent. Totally, 166 of the 222 ESBL-producing isolates had amino acid substitutions in GyrA (S83Y, S83F, D87G, D87N, and D87Y) and ParC (and S80I), whilst the PMQR-encoding genes oqxA/B, qepA, and qnrB/S were detected in almost all isolates. Of the fifteen sequence types (STs) identified in the 222 ESBLs, ST17, ST11, ST34, and ST26 ranked among the top 5 in the number of isolates. Our study revealed considerable serovars diversity, high prevalence of co-occurrence of MDR determinants, including CTX-M-type ESBLs, QRDRs mutations and PMQR genes. This is the first report of CTX-M-130 Salmonella spp. from patients with diarrhea and QRDRs mutations from turtle fecal samples. Our study emphasizes the importance of actions, both in the health care settings and in the veterinary medicine sector, to control the dissemination of MDR, especially the CTX-M Salmonella spp. isolates.

Population Pharmacokinetics and Exposure-Response Relationships of Baloxavir Marboxil in Patients Infected with Influenza at High Risk of Influenza Complications [Clinical Therapeutics]

Baloxavir marboxil, a prodrug of cap-dependent endonuclease inhibitor, baloxavir acid, reduces the time to improvement of influenza symptoms in patients infected with type A or B influenza virus. To characterize its pharmacokinetics, a population pharmacokinetic model for baloxavir acid was developed using 11846 plasma concentration data items from 1827 subjects including 2341 plasma concentration data items from 664 patients at high risk of influenza complications. A three-compartment model with first-order elimination and first-order absorption with lag time well described the plasma concentration data. Body weight and race were found to be the most important factors influencing clearance and volume of distribution. The exposures in high-risk patients were similar to those in otherwise healthy patients, and no pharmacokinetic difference was identified regarding any risk factors for influenza complications.

Exposure-response analyses were performed regarding the time to improvement of symptoms and the reduction in the influenza virus titer in high-risk patients. The analyses suggested that body weight-based dosage, 40 mg for patients weighing < 80 kg and 80 mg for patients weighing ≥ 80 kg, can shorten the time to improvement of influenza symptoms and reduce virus titer for both type A and B influenza virus regardless of the exposure levels of the high-risk patients as well as for the otherwise healthy influenza patients.

The results of our population pharmacokinetic and exposure-response analyses in patients with risk factors of influenza complications should provide useful information on the pharmacokinetic and pharmacodynamic characteristics of baloxavir marboxil and also for the optimization of dose regimens.

Cardiovascular safety and population pharmacokinetic properties of piperaquine in African patients with uncomplicated falciparum malaria - a pooled multicentre analysis [Clinical Therapeutics]

Dihydroartemisinin-piperaquine has shown excellent efficacy and tolerability in malaria treatment. However, concerns have been raised of potentially harmful cardiotoxic effects associated with piperaquine. The population pharmacokinetics and cardiac effects of piperaquine were evaluated in 1,000 patients, mostly children enrolled in a multicentre trial from 10 sites in Africa. A linear relationship described the QTc-prolonging effect of piperaquine, estimating a 5.90ms mean QTc-prolongation per 100ng/mL increase in piperaquine concentration. The effect of piperaquine on absolute QTc-interval estimated a mean maximum QTc-interval of 456ms (EC50=209ng/mL). Simulations from the pharmacokinetic-pharmacodynamic models predicted 1.98-2.46% risk of having QTc-prolongation > 60ms in all treatment settings. Although piperaquine administration resulted in QTc-prolongation, no cardiovascular adverse events were found in these patients. Thus, the use of dihydroartemisinin-piperaquine should not be limited by this concern.

Impact of vanA-positive Enterococcus faecium exhibiting diverse susceptibility phenotypes to glycopeptides on 30-day mortality of patients with a bloodstream infection [Epidemiology and Surveillance]

Introduction: This study was performed to evaluate the impacts of vanA-positivity of Enterococcus faecium (EFM) exhibiting diverse susceptibility phenotypes to glycopeptides on clinical outcomes in patients with a bloodstream infection (BSI) through a prospective, multicenter, observational study.

Methods: A total of 509 patients with an EFM BSI from eight sentinel hospitals in South Korea during a two-year period were enrolled in this study. Risk factors of the hosts and causative EFM isolates were assessed to determine associations with the 30-day mortality of EFM BSI patients via multivariable logistic regression analyses.

Results: The vanA gene was detected in 35.2% (179/509) of EFM isolates; 131 EFM isolates exhibited typical VanA phenotypes (group vanA-VanA), while the remaining 48 EFM isolates exhibited atypical phenotypes (group vanA-Atypical), including VanD (n = 43) and vancomycin-variable phenotypes (n = 5). A multivariable logistic regression indicated that vanA-positivity of causative pathogens was independently associated with the increased 30-day mortality rate in the patients with an EFM BSI; however, there was no significant difference in the survival rates between the patients of the vanA-VanA and vanA-Atypical groups (log-rank test, P = 0.904).

Conclusions: A high 30-day mortality rate was observed in patients with vanA-positive EFM BSIs, and vanA-positivity of causative EFM was an independent risk factor for early mortality irrespective of the susceptibility phenotypes to glycopeptides; thus, intensified antimicrobial stewardship is needed to improve clinical outcome of patients with vanA-positive EFM BSI.

Distribution of linezolid in tuberculosis lesions in patients with spinal multidrug-resistant tuberculosis [Pharmacology]

Linezolid has strong antimicrobial activity against the multidrug-resistant (MDR) strains of Mycobacterium tuberculosis. Little is known about the distribution of linezolid in tuberculosis (TB) lesions in patients with MDR-TB. The aim of this study is to evaluate the distribution of linezolid in TB lesions in patients with spinal MDR-TB. Nine patients with spinal MDR-TB were enrolled prospectively from August 2019 to February 2020. The patients received a linezolid-containing anti-TB treatment regimen and needed surgery for the removal of TB lesions. During the operation, nine blood samples, eight diseased bone tissue samples, seven pus samples and four granulation tissue samples were collected simultaneously and 2 h after the oral administration of 600 mg of linezolid. Linezolid concentrations in plasma, diseased bone tissue, pus, and granulation tissue samples were subjected to high-performance liquid chromatography–tandem mass spectrometry. At sample collection, the mean concentrations of linezolid in plasma, diseased bone tissue, pus, and granulation tissue samples of the nine patients were 11.14 ± 5.82, 5.94 ± 4.27, 11.09 ± 4.58, 14.08 ± 10.61 mg/L, respectively. The mean ratios of linezolid concentration in diseased bone/plasma, pus/plasma, and granulation/plasma were 53.84%, 91.69%, and 103.57%, respectively. The mean ratios of linezolid concentration in pus/plasma and granulation/plasma were higher than those in diseased bone/plasma, and the difference was statistically significant (t =-2.810, p = 0.015; t =-4.901, p = 0.001). In conclusion, linezolid had different concentration distributions in different types of TB infected tissues in patients with spinal MDR-TB.
