Condition Lookup

Immunodeficiency due to HIV/AIDS

Sub-category: Secondary Immunodeficiency Disorders

Symptoms:
persistent fatigue; frequent infections; weight loss; swollen lymph nodes; night sweats; fever; opportunistic infections like pneumocystis pneumonia or kaposi's sarcoma

Root Cause:
HIV infects and destroys CD4+ T cells, leading to a weakened immune system and vulnerability to infections and cancers.

How it's Diagnosed: videos
HIV antibody/antigen tests; CD4+ T cell count; Viral load testing; AIDS diagnosis based on specific opportunistic infections or CD4 count below 200 cells/mm³

Treatment:
Antiretroviral therapy (ART); Prophylaxis for opportunistic infections; Immune-boosting treatments in some cases

Medications:
Antiretroviral therapy (ART), prophylactic antibiotics (e.g., Trimethoprim-Sulfamethoxazole), and vaccines as appropriate.

Prevalence: How common the health condition is within a specific population.
Approximately 39 million people living with HIV globally as of 2022.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Unprotected sexual activity; IV drug use; Mother-to-child transmission; Contaminated blood transfusions

Prognosis: The expected outcome or course of the condition over time.
With ART, individuals can lead near-normal life spans; untreated HIV progresses to AIDS, leading to high mortality.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Opportunistic infections; Cancers (e.g., Kaposi's sarcoma); Neurological disorders; Wasting syndrome

Cancer-related Immunodeficiency

Specialty: Allergies and Immunology

Category: Immunologic Disorders

Sub-category: Secondary Immunodeficiency Disorders

Symptoms:
increased susceptibility to infections; delayed wound healing; fatigue; low blood counts

Root Cause:
Cancer itself or treatments like chemotherapy can suppress the immune system by damaging bone marrow or reducing immune cell function.

How it's Diagnosed: videos
Complete blood count (CBC); Immunoglobulin level testing; Bone marrow biopsy in some cases

Treatment:
Addressing the underlying cancer; Prophylactic antibiotics or antivirals; Immunoglobulin replacement therapy (IVIG); Supportive care to boost immunity

Medications:
Prophylactic antibiotics, antifungals, and colony-stimulating factors (e.g., Filgrastim ) to boost white blood cell counts.

Prevalence: How common the health condition is within a specific population.
Common among cancer patients, particularly those with leukemia, lymphoma, or undergoing chemotherapy.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Type of cancer; intensity of treatment (e.g., chemo, radiation); malnutrition; comorbidities

Prognosis: The expected outcome or course of the condition over time.
Dependent on cancer type, stage, and immune recovery post-treatment.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Sepsis; opportunistic infections; delayed cancer treatments due to infections

Immunodeficiency from Chemotherapy or Immunosuppressive Therapy

Specialty: Allergies and Immunology

Category: Immunologic Disorders

Sub-category: Secondary Immunodeficiency Disorders

Symptoms:
frequent infections; fevers; slow wound healing; mouth sores; low energy

Root Cause:
Chemotherapy or immunosuppressive drugs suppress bone marrow and reduce immune cell production.

How it's Diagnosed: videos
CBC to monitor white blood cell count; Immunoglobulin levels; Clinical history of recurrent infections

Treatment:
Discontinuation or adjustment of immunosuppressive therapy; G-CSF (granulocyte colony-stimulating factor) to boost white blood cells; Prophylactic antibiotics

Medications:
Colony-stimulating factors (e.g., Filgrastim ), prophylactic antimicrobials, and immunoglobulin replacement if necessary.

Prevalence: How common the health condition is within a specific population.
Affects most individuals undergoing intensive chemotherapy or organ transplant recipients on immunosuppressive drugs.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Type and duration of treatment; older age; malnutrition; coexisting conditions like diabetes

Prognosis: The expected outcome or course of the condition over time.
Generally reversible after stopping immunosuppressive therapy; longer recovery if bone marrow is severely affected.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Sepsis; severe infections; delayed recovery of immune function

Immunodeficiency related to Organ Transplantation

Specialty: Allergies and Immunology

Category: Immunologic Disorders

Sub-category: Secondary Immunodeficiency Disorders

Symptoms:
recurrent infections; poor wound healing; fevers; opportunistic infections like cytomegalovirus (cmv)

Root Cause:
Long-term use of immunosuppressive drugs to prevent organ rejection reduces immune surveillance and response.

How it's Diagnosed: videos
CBC; immunoglobulin levels; monitoring for infections

Treatment:
Balancing immunosuppressive drug levels; Prophylactic antimicrobial treatments; Vaccinations prior to transplantation

Medications:
Immunosuppressive medications (e.g., Tacrolimus , Mycophenolate Mofetil) and prophylactic antimicrobials.

Prevalence: How common the health condition is within a specific population.
Common among all organ transplant recipients.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Type of transplant; intensity of immunosuppression; underlying comorbidities

Prognosis: The expected outcome or course of the condition over time.
Long-term survival depends on infection control and organ function; frequent monitoring required.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Chronic infections; opportunistic infections; increased cancer risk
