Infections from Pain Clinic: A Case Study

Based on the scenario, which group of pathogens are most likely to be transmitted via blood and cause an epidemiological outbreak?

Given the described symptoms of fatigue, jaundice, and dark urine, which of these pathogens are most likely responsible for this outbreak?

The nurse anesthetist’s practice of using a single needle and syringe to administer multiple doses of sedation medications leads most directly to the transmission of which type of pathogen?

Which of these viruses is most likely to have caused the 100 infections through needle reuse in the pain clinic?

An investigation reveals patients’ blood contained antibodies against an enveloped icosahedral partially double-stranded DNA virus, which is characteristic of what virus?

Which virus is dependent on HBV for its replication?

Patients' blood samples tested positive for antibodies against an enveloped positive-sense single-stranded RNA virus. What is one shared characteristic of this virus?

Given the information in the case, what is the most likely root cause of the infections?

Case Study 1

In August 2002, the Oklahoma State Department of Health was notified of six patients with blood-borne infections who received treatment at the same pain remediation clinic.

Patient Symptoms

The patients showed signs of fatigue, malaise, anorexia, nausea and vomiting, fever, jaundice, dark-colored urine, abdominal pain, and white stools.

Potential Pathogens

Possible pathogens that could have caused an epidemic outbreak, given the symptoms, are hepatitis B (HBV), hepatitis C (HCV), and hepatitis A (HAV). Human immunodeficiency virus (HIV) is also a possibility, but less likely given the circumstances.

Clinic Investigation

The clinic's equipment was investigated. A certified registered nurse anesthetist was found to have reused needles and syringes multiple times.
A single needle and syringe were used to administer three sedation medications to up to 24 patients in each clinic session. The medication was administered through IV tubes.
Serological testing for blood-borne pathogens was completed on 793 of 908 patients at the clinic. 100 patients were found to have infections possibly acquired there.

Virus Identification

The investigation revealed antibodies to an enveloped, icosahedral, partially double-stranded DNA virus.
The virus that would have likely infected patients was the virus responsible for Hepatitis B (HBV).

Outcomes

80 of the 100 infected patients responded to follow-up inquiries.
20 of the 100 patients developed chronic liver disease, requiring ongoing care.
Liver biopsies in those 20 showed abnormal pathology.

Additional Virus Characteristics

Patients had antibodies to an enveloped positive-sense single-stranded RNA virus. A characteristic of this virus is that it causes chronic infections with a high rate.

Vaccines

A vaccine exists to protect against hepatitis A (HAV), B (HBV), and D (HDV).

Explore this case study of a blood-borne infection outbreak linked to a pain remediation clinic. The patients exhibited symptoms of various hepatitis infections, prompting an investigation into the clinic's practices. Analyze the implications of reused medical equipment and the potential pathogens involved.
