Missed diagnosis of septic arthritis due to invasive pneumococcal disease.

A 61-year-old woman with severe gout, chronic kidney disease, type II diabetes, and heart failure with reduced ejection fraction was admitted with acute onset bilateral hand swelling and pain following a trauma. She was managed for a severe gout flare, but her symptoms, leukocytosis, and inflammatory markers did not improve. Six days into the hospital course, she developed fevers. Blood cultures grew Streptococcus pneumoniae. Intravenous antibiotics were started, and the patient underwent multiple incision and debridements of the bilateral hands with improvement in symptoms and clinical status. Septic arthritis secondary to S. pneumoniae is uncommon. We highlight this case to recognize that septic arthritis should always be considered when a patient presents with a painful, erythematous joint. Pneumococcal vaccination reduces the incidence of invasive pneumococcal disease, and should be prioritized for those at high risk for invasive disease and who are immunocompromised.

Efficacy and Safety of COVID-19 Convalescent Plasma in Hospitalized Patients: A Randomized Clinical Trial.

Importance: There is clinical equipoise for COVID-19 convalescent plasma (CCP) use in patients hospitalized with COVID-19. Objective: To determine the safety and efficacy of CCP compared with placebo in hospitalized patients with COVID-19 receiving noninvasive supplemental oxygen. Design, Setting, and Participants: CONTAIN COVID-19, a randomized, double-blind, placebo-controlled trial of CCP in hospitalized adults with COVID-19, was conducted at 21 US hospitals from April 17, 2020, to March 15, 2021. The trial enrolled 941 participants who were hospitalized for 3 or less days or presented 7 or less days after symptom onset and required noninvasive oxygen supplementation. Interventions: A unit of approximately 250 mL of CCP or equivalent volume of placebo (normal saline). Main Outcomes and Measures: The primary outcome was participant scores on the 11-point World Health Organization (WHO) Ordinal Scale for Clinical Improvement on day 14 after randomization; the secondary outcome was WHO scores determined on day 28. Subgroups were analyzed with respect to age, baseline WHO score, concomitant medications, symptom duration, CCP SARS-CoV-2 titer, baseline SARS-CoV-2 serostatus, and enrollment quarter. Outcomes were analyzed using a bayesian proportional cumulative odds model. Efficacy of CCP was defined as a cumulative adjusted odds ratio (cOR) less than 1 and a clinically meaningful effect as cOR less than 0.8. Results: Of 941 participants randomized (473 to placebo and 468 to CCP), 556 were men (59.1%); median age was 63 years (IQR, 52-73); 373 (39.6%) were Hispanic and 132 (14.0%) were non-Hispanic Black. The cOR for the primary outcome adjusted for site, baseline risk, WHO score, age, sex, and symptom duration was 0.94 (95% credible interval [CrI], 0.75-1.18) with posterior probability (P[cOR<1] = 72%); the cOR for the secondary adjusted outcome was 0.92 (95% CrI, 0.74-1.16; P[cOR<1] = 76%). Exploratory subgroup analyses suggested heterogeneity of treatment effect: at day 28, cORs were 0.72 (95% CrI, 0.46-1.13; P[cOR<1] = 93%) for participants enrolled in April-June 2020 and 0.65 (95% CrI, 0.41 to 1.02; P[cOR<1] = 97%) for those not receiving remdesivir and not receiving corticosteroids at randomization. Median CCP SARS-CoV-2 neutralizing titer used in April to June 2020 was 1:175 (IQR, 76-379). Any adverse events (excluding transfusion reactions) were reported for 39 (8.2%) placebo recipients and 44 (9.4%) CCP recipients (P = .57). Transfusion reactions occurred in 2 (0.4) placebo recipients and 8 (1.7) CCP recipients (P = .06). Conclusions and Relevance: In this trial, CCP did not meet the prespecified primary and secondary outcomes for CCP efficacy. However, high-titer CCP may have benefited participants early in the pandemic when remdesivir and corticosteroids were not in use. Trial Registration: ClinicalTrials.gov Identifier: NCT04364737.

Bacterial and fungal coinfections in COVID-19 patients hospitalized during the New York City pandemic surge.

We observed bacterial or fungal coinfections in COVID-19 patients admitted between March 1 and April 18, 2020 (152 of 4,267, 3.6%). Among these patients, mortality was 57%; 74% were intubated; 51% with bacteremia had central venous catheters. Time to culture positivity was 6-7 days, and 79% had received prior antibiotics. Metallo-ß-lactamase-producing E. cloacae coinfections occurred in 5 patients.

Analysis of catheter utilization, central line associated bloodstream infections, and costs associated with an inpatient critical care-driven vascular access model.

BACKGROUND: Central line-associated bloodstream infections (CLABSI) carry serious risks for patients and financial consequences for hospitals. Avoiding unnecessary temporary central venous catheters (CVC) can reduce CLABSI. Critical Care Medicine (CCM) is often consulted to insert CVC when alternatives are unavailable. We aim to describe clinical and financial implications of a CCM-driven vascular access model. METHODS: In this retrospective, observational cohort study, all CLABSI and a sample of CCM consults for CVC insertion on adult medical-surgical inpatient units were reviewed in 2019. Assessment of CVC appropriateness and financial analysis of labor, reimbursement, and attributable CLABSI cost was conducted. RESULTS: Of 554 CCM consult requests, 75 (13.5%) were for CVC and 36 (48.0%) resulted in CVC insertion; 6 (16.7%) CVC were avoidable. Three CLABSI occurred in avoidable CVC with estimated annual attributable cost of $165,099. Estimated annual CCM consultant cost for CVC was $78,094 generating $110,733 in reimbursement. Overall estimated annual loss was $132,460. DISCUSSION: Reliance on CCM for intravenous access resulted in avoidable CVC, CLABSI, inefficient physician effort, and financial losses; nurse-driven vascular access models offer potential cost savings and risk reduction. CONCLUSIONS: CCM-driven vascular access models may not be cost-effective; alternatives should be considered for utilization reduction, CLABSI prevention, and financial viability.

Fatal influenza myocarditis with incessant ventricular tachycardia.

Influenza myocarditis is an underappreciated and severe complication of influenza infection, estimated to be present in about 10% of all influenza cases. We present a case of a woman who precipitously died of fulminant influenza myocarditis and then review the historical data, literature and expert recommendations for suspecting and managing influenza myocarditis.

Corynebacterium kroppenstedtii: a challenging culprit in breast abscesses and granulomatous mastitis.

PURPOSE OF REVIEW: Corynebacterium kroppenstedtii is a difficult pathogen associated with granulomatous mastitis and recurrent breast abscesses. Despite over a dozen studies, there is no guidance on surgical interventions, steroid use, or dosing or duration of antibiotic treatment. RECENT FINDINGS: Initially seen in predominantly Maori and Pacific Islander multiparous, postlactating women, C. kroppenstedtii breast infection has since been reported throughout the world, including in nulliparous women. Additionally, emerging data suggest that hyperprolactinemia is a modifiable risk factor for these infections. This article reviews a patient case and data from 87 other cases to compile current best practices for diagnosis, treatment, and monitoring, and provides areas for future study. SUMMARY: In cases of granulomatous mastitis and breast abscess, especially if recurrent, infection with C. kroppenstedtii should be considered. Microbiologists should be alerted to the specialized growth conditions and tools needed for appropriate culturing, identification, and antibiotic susceptibility testing. Clinicians should utilize a multimodal approach with surgical and antibiotic treatment to maximize clinical cure and reduce recurrence.

Tuberculosis treatment failure in AIDS: vengeance with renal and ocular manifestations.

Tuberculosis treatment failure is not uncommon in patients with AIDS. Treatment failure is defined as a positive sputum smear or culture at month 5 or later in the course of the treatment. The clinical presentations in these patients show remarkable heterogeneity. In this report, we chronicle the case of a patient with treatment failure presenting as the disseminated disease, specifically ocular and renal tuberculosis. Additionally, we undertake here a brief literature review highlighting the increased resistance to tuberculosis treatment in patients with AIDS, the rarity of ocular tuberculosis and the importance of tailoring drug regimens on an individual basis in these coinfected patients.

Bundle in the Bronx: Impact of a Transition-of-Care Outpatient Parenteral Antibiotic Therapy Bundle on All-Cause 30-Day Hospital Readmissions.

BACKGROUND: A streamlined transition from inpatient to outpatient care can decrease 30-day readmissions. Outpatient parenteral antibiotic therapy (OPAT) programs have not reduced readmissions; an OPAT bundle has been suggested to improve outcomes. We implemented a transition-of-care (TOC) OPAT bundle and assessed the effects on all-cause, 30-day hospital readmission. METHODS: Retrospectively, patients receiving postdischarge intravenous antibiotics were evaluated before and after implementation of a TOC-OPAT program in Bronx, New York, between July, 2015 and February, 2016. Pearson's χ2 test was used to compare 30-day readmissions between groups, and logistic regression was used to adjust for covariates. Time from discharge to readmission was analyzed to assess readmission risk, using log-rank test to compare survival curves and Cox proportional hazards model to adjust for covariates. Secondary outcomes, 30-day emergency department (ED) visits, and mortality were analyzed similarly. RESULTS: Compared with previous standard care (n = 184), the TOC-OPAT group (n = 146) had significantly lower 30-day readmissions before (13.0% vs 26.1%, P < .01) and after adjustment for covariates (odds ratio [OR] = 0.51; 95% confidence interval [CI], 0.27-0.94; P = .03). In time-dependent analyses, TOC-OPAT patients were at significantly lower risk for readmission (log-rank test, P < .01; hazard ratio = 0.56; 95% CI, 0.32-0.97; P = .04). Propensity-matched sensitivity analysis showed lower readmissions in the TOC-OPAT group (13.6% vs 24.6%, P = .04), which was attenuated after adjustment (OR = 0.51; 95% CI, 0.25-1.05; P = .07). Mortality and ED visits were similar in both groups. CONCLUSIONS: Our TOC-OPAT patients had reduced 30-day readmissions compared with the previous standard of care. An effective TOC-OPAT bundle can successfully improve patient outcomes in an economically disadvantaged area.
