Most of us are aware of HIV and how it affects the body. We have been taught how the virus attacks and destroys the immune system. It is not the attack on the immune system that directly kills a person. It’s all those opportunistic infections that eventually weaken and often times finally kill HIV/AIDS patients.
PJP, “pneumocystis jirovecii pneumonia”, is one of the most common opportunistic infections to befall an HIV positive patient. This particular type of pneumonia (or as one of my patients pronounced it “ammonia”) is caused by a fungus commonly found in the environment. For those of us with a normal immune system, it does us no harm. For the immunosuppressed patient, however, it can be dangerous and possibly deadly. For a patient with severe PJP, it can lead to ARDS which has a high mortality rate. Having HIV does not mean a patient will automatically become infected with PJP. The infection typically manifests when the CD4 count is low. This is a really good article describing PJP and its relationship to HIV/AIDS. Here is another good article by Medscape that talks about the fungal pneumonia and how it functions.
You are probably wondering what made me write a blog on a type of pneumonia that you may not have heard of before. Well, I am a nurse and also a state certified HIV tester. HIV is becoming a passion for me. However, that’s not the only reason. See, back when I was a med-surg nurse, we had a patient that I can’t forget. He was a 22-year-old young man that was in and out of the hospital with chest pain, complaints of difficulty breathing, fever, and other rather generic symptoms. His chest CT showed the opacities in the lung. The doctors were sure he had pneumonia but he didn’t respond to most therapies. Furthermore, he’s a young guy, he shouldn’t have a recurrent pneumonia presentation like this. Enter our infectious disease doctor. He decides this guy needs a bronch. We are done guessing, he wants to get a bronchial sample so we can figure out what is going on. They began testing the sample for what type of pneumonia it was and it came back as PJP. He immediately asked for the patient to be tested for HIV. The resident nor I really understood why. Of course, I had to ask. His response? “When I see PJP I think HIV.” I asked him what he meant by that. That’s when he began to tell me about the fungal infection and its relation to immunosuppressed patients. In his words, “you just don’t really see it in people with a healthy immune system. Our guy wasn’t a transplant patient. He wasn’t on chemotherapy. So, what other reason would a man his age possibly be immunosuppressed?” Turns out, he was HIV positive and did not know. His CD4 count was terribly low. I witnessed this man’s life change in the blink of an eye. He didn’t take the news well, but I couldn’t blame him. That was not the last time I saw him. He was in and out of our unit with pneumonia or thrush. He wasn’t really compliant with his meds. No one in his family knew what was going on with him. He wouldn’t allow visitors while he was in the hospital and would sit in his room all alone. It was heartbreaking. Then he stopped coming into the hospital. I held out hope that he had finally started taking his meds and got better. Deep down, I knew that wasn’t the case. Turns out he did come back into the hospital, just not to our unit. This time he was intubated in the ICU. He didn’t make it. He was just too sick and had been sick for far too long. Because of him, because of his case, I will forever remember an obscure pneumonia that I haven’t treated since.
So, I thought I would share a little bit of obscure information because… well… why not?
Are there any cases that stand out to you? Leave a comment and let me know.
