ABSTRACT
Ehrlichioses and anaplasmosis have undergone dramatic increases in incidence, and the geographic ranges of their occurrence and vectors have also expanded. There is marked underreporting of these diseases owing to deficient physician awareness and knowledge of the illnesses as well as limited access to appropriate diagnostic tests. Human monocytic ehrlichiosis and anaplasmosis are life threatening diseases with estimated case fatality rates of 2.7 and 0.3%, respectively. However, knowledge of their full range of signs and symptoms is incomplete, and the incidence of subclinical infections is unknown. Currently available laboratory diagnostic methods are poorly utilized, and with the exception of nucleic acid amplification tests are not useful for diagnosis during the acute stage of illness when timely treatment is needed. The Ehrlichiosis and Anaplasmosis Subcommittee of the Tick-Borne Disease Working Group recommended active clinical surveillance to determine the true incidence, full clinical spectrum, and risk factors for severe illness, as well as standardized surveillance of ticks for these pathogens, and enhanced education of primary medical caregivers and the public regarding these diseases. The subcommittee identified the needs to develop sensitive, specific acute stage diagnostic tests for local clinical laboratories and point-of-care testing, to develop approaches for utilizing electronic medical records, data mining, and artificial intelligence for assisting early diagnosis and treatment, and to develop adjunctive therapies for severe disease.

Suspicion of coronavirus disease in febrile patients might lead to anchoring bias, causing misdiagnosis of other infections for which epidemiologic risks are present. This bias has potentially severe consequences, illustrated by cases of human granulocytic anaplasmosis and Lyme disease in a pregnant woman and human granulocytic anaplasmosis in another person.

BACKGROUND: Emergency department (ED) visits and hospitalizations from skin and soft tissue infections (SSTIs) have been on the rise and have led to an increased clinical and economic burden. Owing to their single-dose regimen, recently approved lipoglycopeptides such as oritavancin have the potential to shift the management of SSTIs from an inpatient to outpatient setting. Limited data exist regarding the use of these drugs in the ED setting. OBJECTIVES: The purpose of this study was to describe the impact that clinical decision support (CDS) incorporation into the computerized physician order entry (CPOE) system had on oritavancin use and to assess compliance with appropriate use guidelines in the ED. METHODS: This was a retrospective cohort study evaluating patients who received oritavancin from September 2016 to May 2018. The patients were assigned to the pre-CDS-implementation group if oritavancin was used between September 13, 2016, and June 28, 2017 and to the post-CDS-implementation group if oritavancin was used between August 28, 2017, and May 25, 2018. There was a 2-month transition period between the 2 study time periods. Patients were excluded if the administration occurred outside of the ED or during the transition period. The primary endpoints were oritavancin use and compliance with the appropriate use guidelines after the implementation. RESULTS: There were 169 oritavancin orders in total, of which 119 met the inclusion criteria. There was a marked decrease in use post-CDS implementation (9.2 orders/mo vs. 3 orders/mo). Among those who were prescribed oritavancin, compliance with the appropriate use guidelines increased; however, this did not reach statistical significance. CONCLUSION: The implementation of the appropriate use guidelines with CDS integration into the CPOE system decreased overall oritavancin use but did not have an impact on compliance with the appropriate use guidelines.

It is well-appreciated that patients with documented penicillin allergies often receive broader-spectrum antibiotics. This practice has been associated with increased antimicrobial resistance and cost. In recent years, considerable efforts have been made to spread awareness on the implications of self-reported penicillin allergies. The use of penicillin skin testing to evaluate for true allergies has been strongly recommended by major organizations for decades. However, testing remains underutilized. Current literature has suggested various models of incorporating penicillin allergy screening and testing by different healthcare practitioners (ie, physicians, allergists, nurses, pharmacists). We suggest broader adoption for the role of pharmacists in the provision of penicillin skin testing. This would help expand the service and maximize the potential benefits of penicillin skin testing.

PURPOSE: To assess the success of order set and pharmacist training improvement (OSPTI) in improving prescription of antiretroviral therapy (ART) in a tertiary care, public, teaching hospital. METHODS: In this pre-OSPTI (January 2012 through June 2013) and post-OSPTI study (July 2013 through September 2014), an infectious disease pharmacist reviewed all patients on ART. A review of intervention data in July 2013 led to order-set changes in the hospital's computerized order entry system for frequently intervened on antiretrovirals: ritonavir, tenofovir, emtricitabine/tenofovir disoproxil fumarate (FTC/TDF), and lamivudine. Concurrently, case-based education modules were conducted to help pharmacists identify ART errors. The number of patients on ART, number of interventions, and types of ritonavir interventions were compared between pre- and post-OSPTI periods. RESULTS: In the pre-OSPTI period, an average of 239 patients were reviewed per quarter compared to an average of 216 per quarter in the post-OSPTI period. After implementing enhanced order sets, the number of interventions decreased by approximately 34% ( P < .0001). The number of ritonavir interventions decreased on average by 45% ( P < .0001), although the types of ritonavir interventions were similar. CONCLUSION: Enhanced antiretroviral order sets and pharmacy education modules improved ART prescription by reducing the overall number of antiretroviral interventions required per quarter. This modality was effective in improving prescribing of ART and reducing the need for pharmacist interventions.

Lyme disease is transmitted by the bite of certain Ixodes ticks, which can also transmit Anaplasma phagocytophilum, the cause of human granulocytic anaplasmosis (HGA). Although culture can be used to identify patients infected with A. phagocytophilum and is the microbiologic gold standard, few studies have evaluated culture-confirmed patients with HGA. We conducted a prospective study in which blood culture was used to detect HGA infection in patients with a compatible clinical illness. Early Lyme disease was defined by the presence of erythema migrans. The epidemiologic, clinical, and laboratory features of 44 patients with culture-confirmed HGA were compared with those of a convenience sample of 62 patients with early Lyme disease. Coinfected patients were excluded. Patients with HGA had more symptoms (P = 0.003) and had a higher body temperature on presentation (P < 0.001) than patients with early Lyme disease. HGA patients were also more likely to have a headache, dizziness, myalgias, abdominal pain, anorexia, leukopenia, lymphopenia, thrombocytopenia, or elevated liver enzymes. A direct correlation between the number of symptoms and the duration of illness at time of presentation (rho = 0.389, P = 0.009) was observed for HGA patients but not for patients with Lyme disease. In conclusion, although there are overlapping features, culture-confirmed HGA is a more severe illness than early Lyme disease.

BACKGROUND: Lyme disease is transmitted by the bite of the Ixodes scapularis tick, which can also transmit Anaplasma phagocytophilum, the cause of human granulocytic anaplasmosis (HGA). Conflicting data exist on the frequency of coinfection and on whether Lyme-HGA coinfected patients have more symptoms than patients with Lyme disease alone. METHODS: Blood culture and serology were used to detect HGA infection in patients with early Lyme disease who presented with erythema migrans. The rate of coinfection was determined using different definitions. The clinical and laboratory features of Lyme-HGA coinfection were compared with that of the individual infections. RESULTS: Among 311 patients with erythema migrans, the frequency of coinfection with HGA varied from 2.3% to 10.0%, depending on the definition used (P < .001). Only 1 of 4 groups with presumed coinfection had significantly more symptoms than patients with Lyme disease alone P < .05. High fever and cytopenia were less common in Lyme-HGA coinfection than in patients with HGA alone. CONCLUSION: The results of this study indicate that how HGA is defined in patients with early Lyme disease has an impact on the apparent rate of coinfection and the severity of illness. The findings also suggest that HGA may be less severe than is usually believed, suggesting the existence of referral bias in testing patients preferentially who present with high fever or cytopenia.

Babesiosis is usually acquired from a tick bite or through a blood transfusion. We report a case of babesiosis in an infant for whom vertical transmission was suggested by evidence of Babesia spp. antibodies in the heel-stick blood sample and confirmed by detection of Babesia spp. DNA in placenta tissue.

We examined New York City Department of Health and Mental Hygiene surveillance data on hepatitis A, malaria, and typhoid to determine the proportion of these diseases related to travel and their geographic distribution. We found that 61% of hepatitis A cases, 100% of malaria cases, and 78% of typhoid cases were travel related and that cases clustered in specific populations and neighborhoods at which public health interventions could be targeted. High-risk groups include Hispanics (for hepatitis A), West Africans living in the Bronx (for malaria), and South Asians (for typhoid).

The duration of HIV infection is usually unknown for most patients entering into HIV care. Data on the frequency at which resistance mutations are detected in these patients are needed to support practical guidance on the use of resistance testing in this clinical situation. Furthermore, little is known about HIV subtype diversity in much of the United States. Therefore, we analyzed the prevalence of drug resistance mutations and nonsubtype B strains of HIV among antiretroviral-naïve individuals presenting for HIV care in New York State between September 2000 and January 2004. Sequences were obtained using a commercial HIV genotyping assay. Seventeen of 151 subjects (11.3%; 95% confidence interval 7.2%-17.3%) had at least one drug-resistance mutation, including 5 subjects with fewer than 200 CD4(+) T cells, indicative of advanced infection. Nucleoside reverse transcriptase inhibitor, non-nucleoside reverse transcriptase inhibitor, and protease inhibitor resistance mutations were detected in 6.6%, 5.3%, and 0.7% of subjects, respectively. Subjects from New York City-based clinics were less likely to have resistant virus than subjects from clinics elsewhere in New York State. Nonsubtype B strains of HIV were detected in 9 (6.0%) individuals and were associated with heterosexual contact. Two nonsubtype B strains from this cohort also carried drug-resistance mutations. These data indicate that drug-resistant virus is frequently detected in antiretroviral-naïve individuals entering HIV care in New York State. Furthermore, a diverse set of nonsubtype B strains were identified and evidence suggests that nonsubtype B strains, including those carrying drug-resistance mutations, are being transmitted in New York State.
