Cholera Vaccine: Recommendations of the Advisory Committee on Immunization Practices, 2022.

THIS REPORT SUMMARIZES ALL RECOMMENDATIONS FROM CDC'S ADVISORY COMMITTEE ON IMMUNIZATION PRACTICES (ACIP) FOR THE USE OF LYOPHILIZED CVD 103-HGR VACCINE (CVD 103-HGR) (VAXCHORA, EMERGENT BIOSOLUTIONS, GAITHERSBURG, MD) IN THE UNITED STATES. THE LIVE ATTENUATED ORAL CHOLERA VACCINE IS DERIVED FROM: Vibrio cholerae O1 and is administered in a single dose. Cholera is a toxin-mediated bacterial gastrointestinal illness caused by toxigenic V. cholerae serogroup O1 or, uncommonly, O139. Up to 10% of infections manifest as severe cholera (i.e., cholera gravis), profuse watery diarrhea that can cause severe dehydration and death within hours. Fluid replacement therapy can reduce the fatality rate to <1%. Risk factors for cholera gravis include high dose exposure, blood group O, increased gastric pH (e.g., from antacid therapy), and partial gastrectomy. Cholera is rare in the United States, but cases occur among travelers to countries where cholera is endemic or epidemic and associated with unsafe water and inadequate sanitation. Travelers might be at increased risk for poor outcomes from cholera if they cannot readily access medical services or if they have a medical condition that would be worsened by dehydration, such as cardiovascular or kidney disease. This report describes previously published ACIP recommendations about use of CVD 103-HgR for adults aged 18-64 years and introduces a new recommendation for use in children and adolescents aged 2-17 years. ACIP recommends CVD 103-HgR, the only cholera vaccine licensed for use in the United States, for prevention of cholera among travelers aged 2-64 years to an area with active cholera transmission. Health care providers can use these guidelines to develop the pretravel consultation for persons traveling to areas with active cholera transmission.

Epidemiology of Cryptosporidiosis, New York City, New York, USA, 1995-20181.

Cryptosporidiosis is a parasitic diarrheal infection that is transmitted by the fecal-oral route. We assessed trends in incidence and demographic characteristics for the 3,984 cases diagnosed during 1995-2018 in New York City, New York, USA, and reported to the New York City Department of Health and Mental Hygiene. Reported cryptosporidiosis incidence decreased with HIV/AIDS treatment rollout in the mid-1990s, but the introduction of syndromic multiplex diagnostic panels in 2015 led to a major increase in incidence and to a shift in the demographic profile of reported patients. Incidence was highest among men 20-59 years of age, who consistently represented most (54%) reported patients. In addition, 30% of interviewed patients reported recent international travel. The burden of cryptosporidiosis in New York City is probably highest among men who have sex with men. Prevention messaging is warranted for men who have sex with men and their healthcare providers, as well as for international travelers.

Salmonellosis Outbreak Detected by Automated Spatiotemporal Analysis - New York City, May-June 2019.

In May 2019, the New York City Department of Health and Mental Hygiene (NYCDOHMH) detected an unusual cluster of five salmonellosis patients via automated spatiotemporal analysis of notifiable diseases using free SaTScan software (1). Within 1 day of cluster detection, graduate student interviewers determined that three of the patients had eaten prepared food from the same grocery store (establishment A) located inside the cluster area. NYCDOHMH initiated an investigation to identify additional cases, establish the cause, and provide control recommendations. Overall, 15 New York City (NYC) residents with laboratory-diagnosed salmonellosis who reported eating food from establishment A were identified. The most commonly consumed food item was chicken, reported by 10 patients. All 11 clinical isolates available were serotyped as Salmonella Blockley, sequenced, and analyzed by core genome multilocus sequence typing; isolates had a median difference of zero alleles. Environmental assessments revealed food not held at the proper temperature, food not cooled properly, and potential cross-contamination during chicken preparation. Elevated fecal coliform counts were found in two of four ready-to-eat food samples collected from establishment A, and Bacillus cereus was detected in three. The outbreak strain of Salmonella was isolated from one patient's leftover chicken. Establishing automated spatiotemporal cluster detection analyses for salmonellosis and other reportable diseases could aid in the detection of geographically focused, community-acquired outbreaks even before laboratory subtyping results become available.

Multiple clusters of hepatitis virus infections associated with anesthesia for outpatient endoscopy procedures.

BACKGROUND & AIMS: Hepatitis B virus (HBV) and hepatitis C virus (HCV) can be transmitted during administration of intravenous anesthesia when medication vials are used for multiple patients using incorrect technique. We investigated an outbreak of acute HBV and HCV infections among patients who received anesthesia during endoscopy procedures from the same anesthesiologist (anesthesiologist 1), in 2 different gastroenterology clinics. METHODS: Chart reviews, patient interviews, clinic site visits and infection control assessments, and molecular sequencing of patient isolates were performed. Patients treated by anesthesiologist 1 on specific procedure days were offered testing for blood-borne pathogens. Endoscopy and anesthesia procedures were reviewed; HCV quasispecies analysis was performed. RESULTS: Six cases of outbreak-associated HCV infection and 6 cases of outbreak-associated HBV infection were identified in clinic 1. One outbreak-associated HCV infection was identified in clinic 2. HCV quasispecies sequences from the patients were nearly identical (96.9%-100%) to those from source patients with chronic viral hepatitis. All affected patients in both clinics received propofol from anesthesiologist 1, who inappropriately used a single-patient-use vial of propofol for multiple patients. Reuse of syringes to redose patients, with resulting contamination of medication vials used for subsequent patients, likely resulted in viral transmission. CONCLUSIONS: Twelve persons acquired HBV and HCV infections (6 hepatitis C, 5 hepatitis B, and 1 coinfection) in 2 separate offices as a result of receiving anesthesia from anesthesiologist 1. Gastroenterologists are urged to review carefully the injection, medication handling, and other infection control practices of all staff under their supervision, including providers of anesthesia services.

Extensively Drug-Resistant Typhoid Fever in the United States.

Cases of extensively drug-resistant (XDR) typhoid fever have been reported in the United States among patients who did not travel internationally. Clinicians should consider if and where the patient traveled when selecting empiric treatment for typhoid fever. XDR typhoid fever should be treated with a carbapenem, azithromycin, or both.

Diagnosis and minimally invasive resection of an insulinoma: report of an unusual case and review of the literature.

Insulinomas are rare endocrine tumors that are usually diagnosed by inappropriate elevations in insulin and C-peptide during hypoglycemia. We report a case of a surgically confirmed insulinoma diagnosed by a mild elevation in proinsulin with suppressed insulin and C-peptide at the time of hypoglycemia during a supervised fast. A supervised fast with serial measurements of plasma glucose, insulin, and C-peptide was performed in a patient with documented hypoglycemia. Proinsulin was measured at the beginning and end of the fast. Tumor localization was accomplished with spiral CT, magnetic resonance imaging, and endoscopic ultrasound. Minimally invasive tumor resection was performed. The presence of an insulinoma was confirmed on the basis of a minimally elevated proinsulin level with a suppressed insulin level at the time of symptomatic hypoglycemia. Tumor resection was performed without complications, resulting in resolution of the hypoglycemia. This case demonstrates the importance of measuring proinsulin as a routine component of the 72-hour fast for detection of an insulinoma. Even mild elevations in circulating proinsulin can be an independent indicator of aberrant insulin secretion during hypoglycemia. Once the diagnosis of insulinoma is made and tumor localization is achieved, minimally invasive tumor resection is a safe and effective treatment modality.

Paying for prevention: a critical opportunity for public health.

Despite spending an increasing amount on health care and more than every other industrialized country, the U.S. ranks 37th in health outcomes. The implementation of the Patient Protection and Affordable Care Act (ACA) promises to ensure better access to health care for many Americans through expanded public and private insurance coverage, including basic preventive health care. Public health must seize this critical opportunity by taking steps to ensure that prevention, especially primary prevention, is embedded in our health system. This manuscript outlines four areas where public health officials across the U.S. can immediately capitalize on opportunities created by the ACA to ensure that prevention is a key component of health reform: (1) leading the way on community health assessments; (2) linking clinical and community prevention; (3) supporting the development of alternative payment methodologies to pay for prevention; and (4) serving as a community resource for the coordination of care and building the non-traditional health workforce.

Association of socioeconomic status with mortality in type 1 diabetes: the Pittsburgh epidemiology of diabetes complications study.

PURPOSE: Socioeconomic status (SES) as a risk factor for mortality in type 1 diabetes (T1D) has not been adequately studied prospectively. METHODS: Complete clinical and SES (income, education, occupation) data were available for 317 T1D participants in the Pittsburgh Epidemiology of Diabetes Complications Study within 4 years of age 28 (chosen to maximize income, education, and occupational potential, and to minimize the SES effect of advanced diabetes complications). Vital status was determined as of 1/1/2008. RESULTS: Over a median 16 years of follow-up, 34 (10.7%) deaths occurred (standardized mortality ratios [SMRs] = 4.1, 95% confidence interval [CI]: 2.7-5.5). SMRs did not differ from the general population for those in the highest education and income groups, whereas in those with low SES, SMRs were increased. Mortality rates were three times lower for individuals with a college degree versus without a college degree (p = 0.004) and nearly four times lower for the highest income versus lower income groups (p = 0.04). In Cox models adjusting for diabetes duration and sex, education was the only SES measure predictive of mortality (hazard ratio [HR] = 3.0, 95% CI: 1.2-7.8), but lost significance after adjusting for HbA(1c), non-HDL cholesterol, hypertension, and microalbuminuria (HR = 2.1, 95% CI: 0.8-5.6). CONCLUSIONS: The strong association of education with mortality in T1D is partially mediated by better glycemic, lipid, and blood pressure control.

Associations between socioeconomic status and major complications in type 1 diabetes: the Pittsburgh epidemiology of diabetes complication (EDC) Study.

PURPOSE: To understand the effect of socioeconomic status (SES) on the risk of complications in type 1 diabetes (T1D), we explored the relationship between SES and major diabetes complications in a prospective, observational T1D cohort study. METHODS: Complete data were available for 317 T1D persons within 4 years of age 28 (ages 24-32) in the Pittsburgh Epidemiology of Diabetes Complications Study. Age 28 was selected to maximize income, education, and occupation potential and to minimize the effect of advanced diabetes complications on SES. RESULTS: The incidences over 1 to 20 years' follow-up of end-stage renal disease and coronary artery disease were two to three times greater for T1D individuals without, compared with those with a college degree (p < .05 for both), whereas the incidence of autonomic neuropathy was significantly greater for low-income and/or nonprofessional participants (p < .05 for both). HbA(1c) was inversely associated only with income level. In sex- and diabetes duration-adjusted Cox models, lower education predicted end-stage renal disease (hazard ratio [HR], 2.9; 95% confidence interval [95% CI], 1.1-7.7) and coronary artery disease (HR, 2.5, 95% CI, 1.3-4.9), whereas lower income predicted autonomic neuropathy (HR, 1.7; 95% CI, 1.0-2.9) and lower-extremity arterial disease (HR, 3.7; 95% CI, 1.1-11.9). CONCLUSIONS: These associations, partially mediated by clinical risk factors, suggest that lower SES T1D individuals may have poorer self-management and, thus, greater complications from diabetes.
