I**mmunosuppressant: Cyclosporine** Uses: An immune Suppressant used in organ transplant recipients and autoimmune diseases. Patient Education: Take at the same time daily. **Avoid Grapefruit juice** (interferes with metabolism). Watch for signs of infection. Practice good oral hygiene to prevent gingival hyperplasia. Adverse Effects: Hirsutism: usually resolves once medication is stopped **Bone Marrow** Suppression (s/s = severe infections) Decreased urine output (Nephrotoxicity **Immunostimulant: Vaccines** - General Recommendations: Encourage vaccination based on CDC guidelines. - Immunocompromised patients should avoid live vaccines. - Vaccines are active forms of immunity, meaning they introduce a weakened pathogen to a patient to create an immune response. - Booster Shots allow for continued/sustained immunity. Vaccine Indications/Education --------- ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- HPV 2 dose series prior to the 15 birthday, 6 months in between doses. 3 dose series after the 15^th^ birthday. Recommended for both male and female patients. This is one of two vaccines that helps prevent cancer. HEP B 3 dose series, part of routine childhood vaccination schedule. Reduces risk of Chronic hepatitis, liver cancer, and cirrhosis DTaP 5 dose series, starts at 2 months old. Can cause a localized reaction (red, swollen, usually self-limited). This prevents Diphtheria, tetanus, and pertussis IPV 4 dose series, if needed accelerated schedule can be used for out of country travel. This prevents Polio. MMR 2 dose series, starts at 12 months old. This is a live vaccine, should not be used on pregnant people, or immunocompromised. This protects against measles, mumps, and rubella. +-----------+-----------+-----------+-----------+-----------+-----------+ | **Class** | **Gram** | **Example | **Mech of | **Importa | **Risk of | | | | ** | Action** | nt | SuperInfx | | | | | | to | ** | | | | | | Remember* | | | | | | | * | | +===========+===========+===========+===========+===========+===========+ | Penicilli | Pos | Penicilli | Inhibits | Rash | Mild risk | | n | | n | cell wall | occurs | | | | Neg | G | synthesis | | | | | | | | | | | | | Ampicilli | | | | | | | n | | | | | | | | | | | | | | Methicill | | | | | | | in | | | | | | | | | | | | | | Amoxicill | | | | | | | in | | | | +-----------+-----------+-----------+-----------+-----------+-----------+ | Cephalosp | Pos | Cefazolin | Inhibits | Mostly | Later | | orins | | | cell wall | used for | generatio | | | Neg | Ceftriaxo | synthesis | gram | ns | | | | ne | | negative | are | | | | | | infection | increased | | | | | | s. | risk | | | | | | Cross | | | | | | | sensitivi | | | | | | | ty | | | | | | | is | | | | | | | possible | | | | | | | with | | | | | | | penicilli | | | | | | | n | | +-----------+-----------+-----------+-----------+-----------+-----------+ | Tetracycl | Pos | Tetracycl | Inhibits | Causes | High risk | | ines | | ine | protein | discolora | | | | Neg | | synthesis | tion | | | | | Doxycycli | | of teeth, | | | | | ne | | no milk | | | | | | | or iron. | | | | | | | Do not | | | | | | | take if | | | | | | | pregnant | | | | | | | or less | | | | | | | than 8 | | | | | | | years old | | +-----------+-----------+-----------+-----------+-----------+-----------+ | Macrolide | Pos | Azithromy | Inhibits | Alternati | Increased | | s | | cin | protein | ve | risk | | | | | synthesis | to | | | | | Erythromy | by | penicilli | | | | | cin | binding | n | | | | | | to the | for PT | | | | | | bacterial | who is | | | | | | ribosome | allergic | | | | | | | to | | | | | | | penicilli | | | | | | | n | | +-----------+-----------+-----------+-----------+-----------+-----------+ | Aminoglyc | Neg | Gentamici | Inhibits | Used for | High | | osides | | n | protein | serious | | | | | | synthesis | systemic | | | | | Streptomy | | infection | | | | | cin | | s | | | | | | | r/t | | | | | | | aerobic | | | | | | | gram | | | | | | | organism. | | | | | | | BBW- | | | | | | | nephrotox | | | | | | | icity | | | | | | | and | | | | | | | ototoxici | | | | | | | ty | | +-----------+-----------+-----------+-----------+-----------+-----------+ | Fluoroqui | Pos | Ciproflax | Inhibits | Tendon | Increased | | nolones | | in | DNA | rupture | risk | | | Neg | | replicati | risk | | | | | | on | | | | | | | | No iron | | | | | | | or | | | | | | | antacids | | +-----------+-----------+-----------+-----------+-----------+-----------+ | Sulfonami | Pos | Sulfameth | Inhibits | Increased | Increased | | des | | oxazole | folate | resistanc | | | | Neg | | synthesis | e, | | | | | | | if rash | | | | | | | occurs | | | | | | | stop | | | | | | | medicatio | | | | | | | n | | +-----------+-----------+-----------+-----------+-----------+-----------+ | **Misc | | | | | | | ABX:** | | | | | | +-----------+-----------+-----------+-----------+-----------+-----------+ | Carbapene | Pos | Imipenem | Inhibits | Used for | Increased | | ms | | | cell wall | complicat | risk | | | Neg | | construct | ed | | | | | | ion | UTI | | | | | | with | | | | | | | Beta-lact | | | | | | | am | | | | | | | ring | | | +-----------+-----------+-----------+-----------+-----------+-----------+ | Clindamyc | Pos Neg | Cleocin | Inhibits | Cause a | High | | in | | | protein | complicat | | | | | | synthesis | ion | | | | | | | related | | | | | | | to C. | | | | | | | Diff | | | | | | | (BBW) | | +-----------+-----------+-----------+-----------+-----------+-----------+ | Linezolid | Pos Neg | Oxazolidi | Inhibits | Alternate | High | | | | nones | protein | treatment | | | | | | synthesis | for MRSA, | | | | | | | VRE | | | | | | | infection | | +-----------+-----------+-----------+-----------+-----------+-----------+ | Metronida | Pos | Flagyl | Inhibits | Dual | High | | zole | | | DNA and | activity | | | | Neg | | protein | as | | | | | | synthesis | antibioti | | | | | | | c | | | | | | | and | | | | | | | antiproto | | | | | | | zoal | | +-----------+-----------+-----------+-----------+-----------+-----------+ | Vancomyci | Pos | Glycopept | Inhibits | Redman | High | | n | | ides | cell wall | syndrome | | | | | | synthesis | | | | | | | | Nephrotox | | | | | | | ic | | | | | | | | | | | | | | Ototoxic | | | | | | | | | | | | | | Reserved | | | | | | | for | | | | | | | infection | | | | | | | | | | | | | | Unrespons | | | | | | | ive | | | | | | | to safer | | | | | | | antibioti | | | | | | | c | | +-----------+-----------+-----------+-----------+-----------+-----------+ **Signs of Vancomycin Toxicity** Nephrotoxicity: Increased creatinine, decreased urine output.

It is considered the 1^st^ line of tx by most providers. Methotrexate Contraindications Pregnancy (teratogenic). Nursing Considerations: Monitor liver and kidney function, assess for signs of bone marrow suppression and provide patient education on contraception. **Biologics (Adalimumab):** Slows disease progression. Target specific components of the immune response. **Nursing Considerations: assess for signs of infection.** **NSAIDS:** purpose is to help manage acute pain and inflammation. **Nursing considerations: monitor for s/s of GI upset/bleeding.** **Gout**: A form of arthritis caused by the accumulation of uric acid crystals in joints. **Common Medications:** - **Allopurinol:** Decreases uric acid production. - **NSAIDs** ** Nursing Considerations:** Encourage hydration to help excrete uric acid. Avoid purine-rich foods (red meats, alcohol). HIV and Antiviral Therapy: An Overview for Nursing Students Human Immunodeficiency Virus (HIV) is a retrovirus that targets the immune system, specifically CD4 cells (T-helper cells), leading to a gradual loss of immune function. Without treatment, HIV can progress to acquired immunodeficiency syndrome (AIDS). Antiviral therapy, particularly Antiretroviral Therapy (ART), is essential in managing HIV infection, reducing viral load, and maintaining immune function. The primary goal of ART is to prevent HIV replication, thereby slowing disease progression, reducing the risk of transmission, and improving the patient's quality of life. Antiviral Therapy in HIV ART typically involves the use of a combination of antiretroviral drugs from different classes to maximize efficacy and prevent resistance. The main classes of antiretrovirals include: 1\. Nucleoside Reverse Transcriptase Inhibitors (NRTIs) 2\. Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs) 3\. Protease Inhibitors (PIs) 4\. Integrase Inhibitors 5\. Entry Inhibitors Zidovudine (AZT) Zidovudine, also known as AZT, Nucleoside Reverse Transcriptase Inhibitor (NRTI) and was the first drug approved for the treatment of HIV. Zidovudine works by inhibiting the reverse transcriptase enzyme, which is critical for HIV replication. Although newer drugs have surpassed zidovudine in efficacy and safety, it remains a key drug in certain ART regimens, particularly in preventing mother-to-child transmission during pregnancy. Key points for nursing students: Mechanism of Action: Zidovudine acts by inhibiting the reverse transcriptase enzyme, which is needed for HIV to convert its RNA into DNA. Indications: Used as part of combination therapy for HIV treatment and for the prevention of perinatal transmission of HIV. **Side Effects:** Zidovudine has a well-known side effect profile that includes: **Nursing Considerations:** - Monitor CBC (complete blood count) regularly to watch for signs of anemia or neutropenia. - Educate patients on the importance of adherence to prevent viral resistance. - Watch for signs of myopathy (e.g., muscle pain or weakness) and hepatotoxicity (e.g., jaundice, abdominal pain). - In pregnancy, closely monitor both mother and infant to reduce the risk of HIV transmission. - **Continue to promote safe sex even when on therapy.** Acyclovir While acyclovir is an antiviral, it is used for the management of herpes simplex virus (HSV) infections. Acyclovir **inhibits viral DNA replication,** limiting the spread of HSV infections. Mechanism of Action: Indications: Used primarily for Herpes Simplex 1, Herpes Simplex 2, and varicella-zoster infections. Side Effects: Generally well-tolerated but can cause nephrotoxicity, neurotoxicity, and gastrointestinal symptoms (nausea, vomiting, diarrhea). Nursing Considerations: - **Give medication around the clock. Typically, prescribed 3-4 times in a 24-hour period, topically can be up to 5 times daily.** **Medications that increase the risk of osteoporosis -- corticosteroids, anticonvulsants, diuretics** Raloxifene is preventative for post menopausal women for osteoporosis For kidney and liver disease and blood thinners don't take antivirals, antifungals, antibiotics Tetracycline worry about photosensitivity Diuretics -- lower serum calcium levels Calcium slates -- not Po just iv one hour before meals Calcium slates are bonded to phosphate and carbonate Pregnant women can have penicillin DMARDS- methotrexate, adalimumb, lefluomide, hydroxychloroquine
