By now most people in the United States have heard about the current outbreak of fungal meningitis in the United States that has been linked to contaminated epidural steroid injections manufactured by a compounding pharmacy headquartered in Massachusetts. Three lots of the potentially contaminated epidural steroid injections were recalled by the manufacturer on September 26, 2012. Almost 14,000 people have possibly received the contaminated injections from the recalled lots. As of October 13, 2012, the CDC reported that there have been 198 confirmed cases of fungal meningitis in 13 states that have resulted in 15 deaths. A list of the healthcare facilities that received the recalled epidural steroid injections can be viewed by clicking here.
The CDC issued a press release on October 12, 2012 that provides the chronology of the fungal meningitis outbreak. The press release states, in part:
On September 18, 2012, the Tennessee Department of Health was alerted by a clinician regarding a patient with culture-confirmed Aspergillus fumigatus meningitis diagnosed 46 days after epidural steroid injection at a Tennessee ambulatory surgical center. By September 27, the initial investigation, carried out by the Tennessee Department of Health in collaboration with CDC and the North Carolina Department of Health and Human Services, had identified an additional eight patients with clinically diagnosed, culture-negative meningitis: seven in Tennessee and one in North Carolina. All nine patients had received epidural steroid injection with preservative-free methylprednisolone acetate solution (MPA), compounded at New England Compounding Center (NECC) in Framingham, Massachusetts. All nine patients had received one or more injections from three lots of MPA (lot numbers [email protected]; [email protected]; and [email protected]). As of October 10, a multistate investigation led by CDC in collaboration with state and local health departments and the Food and Drug Administration (FDA) had identified 137 cases and 12 deaths associated with this outbreak in 10 states. Active case-finding efforts and extensive investigation into medications and medication lot numbers received by patients have confirmed that, as of October 10, no cases were associated with other lots of MPA, nor were any associated with other NECC products.
NECC was informed of the ongoing investigation on September 25 and provided invoice information indicating that approximately 17,500 vials of MPA (80 mg/ml) from these lots were packaged in 1ml, 2ml, and 5ml vials and distributed to 75 facilities in 23 states. These lots of MPA were used to treat both peripheral joint and back pain. On September 26, NECC voluntarily recalled the three lots of MPA, followed by an expanded voluntary recall of all lots of MPA and all lots of sterile products intended for intrathecal injection on October 3. This was followed by a voluntary recall of all remaining products on October 6.
Some patients received multiple injections with the three lots of MPA, and some vials were unused. As of October 10, state and local health departments had identified almost 14,000 persons potentially exposed to medications from at least one of these lots. Active notification of exposed persons was initiated by state health departments and CDC on September 25. Passive case finding was conducted by widely disseminated notices of the potential contamination of the three MPA lots via Epi-X (a CDC electronic public health notification system), through professional societies and listservs, and the news media. As of October 10, state health departments had reported that approximately 90% of patients exposed to medication from one of the three lots of MPA recalled on September 26 had been contacted at least once, by telephone, voicemail, home visit, or registered mail.
As of October 10, four categories of cases in patients who received an injection with MPA produced by NECC had been identified: 1) fungal meningitis or nonbacterial and nonviral meningitis of subacute onset following epidural injection on or after May 21; 2) basilar stroke following epidural injection on or after May 21, in a person from whom no cerebrospinal fluid (CSF) specimen was obtained; 3) spinal osteomyelitis or epidural abscess at the site of injection following epidural or sacroiliac injection on or after May 21; 4) septic arthritis or osteomyelitis of a peripheral joint (e.g., knee) diagnosed following injection of that joint on or after May 21. Clinical meningitis was defined as having one or more symptoms (e.g., headache, fever, stiff neck, or photophobia) and CSF pleocytosis (more than five white blood cells per µL, adjusting for presence of red blood cells), regardless of CSF protein and glucose levels. Clinically diagnosed septic arthritis was defined as new or worsening pain with presence of effusion or new or worsening effusion.
As of October 10, 137 patients in 10 states had been identified who met one or more of the four definitions, all of whom underwent injection with one or more of the three lots of MPA from NECC. No cases associated with other lots of MPA, or other NECC products, had been identified. Twelve (9%) of the 137 patients died. Preliminary data are available on 70 (51%) patients. Of these, 64 (91%) have meningitis (case definition 1). Of the six remaining patients, two (3%) have stroke without lumbar puncture (definition 2), and two (3%) have an epidural abscess or osteomyelitis (definition 3). Two (3%) patients met more than one case definition (definitions 1 and 3).
Median age of the 70 patients is 68 years (range: 23–91 years); 48 (69%) are female. At presentation, 57 (81%) had headache, 24 (34%) had fever, 21 (30%) had nausea, and seven (10%) had photophobia. Atypical neurologic symptoms were observed in a minority of patients; subtle gait disturbances were seen in three (4%), and a history of falls was described in eight (11%). Meningeal signs, including nuchal rigidity, Kernig’s sign, or Brudzinski’s sign, were uncommon, occurring in 10 (14%) patients. Stroke, either as a presenting sign, or as a complication of infection, occurred in 12 (17%).
Median CSF white blood cell count was 1,299/µL (range: 13–15,400) with a neutrophilic predominance; median CSF glucose was 42 mg/dL (range: 11–121), and median protein was 129 mg/dL (range: 45–588). As of October 10, evidence of a fungal infection had been found in 26 (37%) patients by culture, histopathology, or polymerase chain reaction. The fungal species had been identified in 14 patients; Exserohilum spp was identified in 13, and Aspergillus fumigatus was identified in one patient. Further specimen evaluation is ongoing at CDC and state public health and local laboratories.
For the 61 patients with symptom onset date available, the earliest date was August 18. For the 48 patients with both injection date and symptom onset date available for analysis, the median time from last steroid injection to onset of symptoms was 15 days (range: 1–42). A total of 25 of the 48 patients received a single steroid injection; the median time from injection to onset of symptoms for these patients was 16 days (range: 4–42).
