Treatment can lower ones immunity by decreasing the number and function of immune cells. Also, immune suppression is associated with the increased risk of lymphoma, and the disease itself can reduce immune competence and make one prone to invasive infection.
Here we provide resources for serious infections related to late stage or advanced disease and associated with aggressive treatments.
It is particularly important for immune-compromised patients to avoid sources of infection, such as crowded public location, and to take other precautions. See Avoiding infection.
Symptoms of infection may include:
Fever, chills, shaking, lethargy, poor appetite, dizziness, confusion, inflammation,
sensation of heat, and organ-specific signs - mucous-producing cough, painful urination, and so on.
When in doubt, please notify your doctor.
Sepsis is a blood infection that can lead to shock and death. Symptoms may include: Fever (but sometimes normal or low temperature), chills, severe shaking, fast heart rate, rapid breathing, confusion, disorientation, agitation, dizziness, decreased urination, rash, and joint pain.
NIH: Guidance: Call your doctor right away
if you have any of these symptoms:
|
Fever over 100° F or 38° C.
|
|
Chills, especially shaking chills.
|
|
Sweating.
|
|
Loose bowel movements.
|
|
Frequent urgency to urinate or a burning feeling when you urinate.
|
|
A severe cough or sore throat.
|
|
Unusual vaginal discharge or itching.
|
|
Redness, swelling, or tenderness, especially around a wound, sore,
ostomy (surgical opening), pimple, rectal area or catheter site.
|
|
Sinus pain or pressure.
|
|
Earaches, headaches, or stiff neck.

Clostridium difficile infection (C-Diff) is responsible for approximately 3 million cases of diarrhea and colitis annually in the United States. The mortality rate is 1 to 2.5 percent. Early diagnosis and prompt aggressive treatment are critical in managing C. difficile–associated diarrhea.

Infectious Pulmonary Complications
TOPIC SEARCH: Scholar
"Pulmonary complications of cancer and cancer therapy represent a broad spectrum of disease. Early diagnosis and treatment are essential to achieve an optimal outcome." 2
Following Stem Cell Transplant:
"Despite the introduction of numerous prophylactic [preventive] strategies and advances in diagnosis and treatment, pneumonia remains the leading infectious cause of death after HSC transplantation.
... Factors that enhance the vulnerability of the recipient to pneumonia include protracted [long lasting] neutropenia [low immune cell count] before engraftment, impaired humoral [b-cell] and cellular [t-cell] immunity associated with the administration of exogenous immunosuppressive agents, and GVHD [Graft versus Host Disease]." 1, Page 33
Early recognition and correct treatment of the pulmonary complications should minimize the significant mortality and morbidity. This review aims to discuss the role of radiology in the diagnosis and management of pulmonary complications following BMT. 3

Antifungal Treatment Delays Responsible For Excess Deaths From Fungal Infection: Presented at ICAAC
"Among patients who received effective therapy within 6 hours of hypotension onset, the in-hospital survival rate exceeded 60%, with no marked difference between types of infection. Survival rates for both fungal and bacterial infection decreased dramatically as treatment delays grew longer."

FDA Approves Novel Medicine to Prevent Invasive Fungal Infections FDA.gov 2006
The safety and efficacy of Noxafil were evaluated in clinical trials consisting of 1,844 patients between 13 and 82 years of age. In two, randomized, controlled studies of patients who had compromised immunity and were at high risk for invasive fungal infections, those patients who received Noxafil had comparable or lower rates of invasive Aspergillus and Candida infections than those patients who received other antifungal medications.

Aspergillosis MedlinePlus
Aspergillus, a fungus, "causes illness in three ways: as an allergic reaction in people with asthma (Pulmonary aspergillosis - allergic bronchopulmonary type); as a colonization and growth in an old healed lung cavity from previous disease (such as tuberculosis or lung abscess) where it produces a fungus ball called aspergilloma; and as an invasive infection with pneumonia that is spread to other parts of the body by the bloodstream (Pulmonary aspergillosis - invasive type)." ~ MedlinePlus
