It started with a runny nose and sneezing last weekend. Then came a cough and a mild fever that never went above 99.7 Fahrenheit – that is until the following Wednesday. A brief telephone discussion with the doctor on call late that evening confirmed that a trip to Memorial Sloan-Kettering Cancer Center’s (MSKCCs) urgent care facility was in order.
Following my latest round of chemotherapy, a fever of 100.4 Fahrenheit or higher is disconcerting. It could signal that I’m neutropenic – running dangerously low on a type of white blood cell (neutrophils) that serve as the body’s primary defense against acute bacterial and certain fungal infections. The chemotherapy I’ve been receiving can reduce the number of neutrophils circulating in the blood. Alternatively, a fever could be associated with the flu, which is particularly dangerous this season and breaking records.
Lorie and I started packing for an overnight stay at the MSKCC “bed and breakfast” as we like to call it. Before heading out, I hugged each of our dogs – just in case. Unfortunately, that simple action set into motion a rush of feelings and steady stream of tears down my cheeks. I was a total mess by the time Lorie backed the car out from the garage. Our daughters weren’t home at the time, which in retrospect was probably best.
At first, I failed to appreciate why Lorie attempted to set a new land speed record for shortest travel time between Bucks County, PA and New York City. Then, I remembered how I narrowly missed having a tachycardia event (abnormally fast heart rate) on the New Jersey Turnpike during our last trip to MSKCC’s urgent care facility in August 2017 when I ended up in the ICU.
Upon arrival at urgent care just before midnight, a series of tests were ordered – blood work, urine, chest x-ray, and nasal swab to test for influenza. The blood work came back first and my absolute neutrophil count (ANC) was 800 cells per microliter of blood. With an ANC below 1,000 cells per microliter of blood, the risk of infection increases. Combined with my fever, the medical team informed me that I was going to be admitted to the hospital and given a broad spectrum, intravenous antibiotic Zosyn® (piperacillin and tazobactam).
One by one, the other test results came back normal – that is until the nasal swab revealed I was positive for Influenza B. Influenza A and B are the two main types that routinely spread in humans and cause seasonal flu epidemics. Fortunately, I had received a flu shot this season, as this can help reduce the severity of the virus.
Alas, being hospitalized ended the longest “uneventful” streak of my cancer experience. But for six glorious months, living with cancer was relatively dull and boring. And it was wonderful.
With the source of my fever identified as the flu, I was prescribed Tamiflu® (oseltamivir phosphate) and the general plan was to release me from the hospital as soon as my ANC returned to 1,000 or higher. My prior chemotherapy was given on January 30th, so its adverse effect on my blood counts should be diminishing. Patients often have their lowest number (called a nadir) and highest risk of infection around 7 to 10 days after the start of chemotherapy.
However, my next ANC count was 400. When ANC falls below 500 cells per microliter (severe neutropenia), the risk of infection increases significantly. Accordingly, my stay at the bed and breakfast was extended.
By Friday, my ANC rebounded slightly to 700. Heading in the right direction, but still below the 1,000-level needed for my release home. I felt much better than when I was admitted, which was frustrating. In fact, the fever went away as did a runny nose, sneezing, and coughing.
A repeat blood test was scheduled for very early Saturday morning, with the expectation that my ANC would finally rise above 1,000 and we’d be sent home. Or so I hoped. But the test results showed a slight decrease from the prior day to 600.
I was then given a shot of Neupogen® (filgrastim), which works like a natural protein in your body to promote the growth of new white blood cells. Interestingly, Neupogen was among the very first biotechnology products that I learned about during my introduction to the sector in the late 1990s. It was approved by the Food and Drug Administration (FDA) back in 1991.
My blood counts will continue to be monitored until the ANC improves, but sometimes it can take 24-hours to see the effect of Neupogen. And so, we wait.
