00:00 Now let's walk through some key clinical takeaways for treating fungal skin infection. 00:07 Accurate diagnosis through clinical examination, microscopy, and culture is essential before initiating antifungal therapy. 00:15 You want to make sure that the treatment is matched to the pathogen, so the antifungals will be selected based on the specific fungal organism and the infection site. 00:25 Think about the patient's factors. 00:27 Assess for comorbidities, other drug interactions, and special populations like patients who are pregnant, pediatric patients, or renal hepatic impairment. 00:38 Monitor the drug for efficacy and toxicity. 00:41 We want to make sure it's doing what we want it to do in the treatment plan, but it's not putting the patient at risk. 00:46 So follow the appropriate monitoring parameters and adjust the therapy as needed. 00:51 Monitor duration to make sure the patient completes the full treatment course so we can prevent recurrence and resistance. 00:58 Now I know we touched on monitoring for efficacy and toxicity, but I want to dig deeper into that. 01:05 So it's important that all of us follow appropriate monitoring parameters and we want to be part of the team that's adjusting the therapy as needed. 01:12 So let's start with a framework of four broad categories. 01:16 First you're going to monitor for hepatotoxicity. 01:20 Second, you're going to monitor for cardiac effects, particularly with itraconazole. 01:25 Third, you want to watch for severe skin reactions or anaphylaxis. 01:30 And fourth, the drug interaction effects. 01:34 So let's take a look at that. 01:36 What are we looking for in signs of hepatotoxicity or liver dysfunction? Well think about their skin and their eyes. 01:43 That may be a sign of jaundice if you see them turning yellow. 01:46 The patient might complain of right upper quadrant abdominal pain. 01:50 The patient may have some unexplained nausea or vomiting. 01:54 They may feel extra tired. 01:56 Their urine may be darker and their stool may be lighter. 02:00 These are all signs that the liver is struggling. 02:03 And if the patient is on an oral antifungal, this is reason for alarm. 02:08 Now we'll come to the cardiac effects. 02:10 Remember that's that second category, but we're specifically talking about itraconazole. 02:14 So this could cause signs of heart failure. 02:16 You know, the typical ones, shortness of breath, edema, and unusual fatigue. 02:21 But remember that is specific to this oral antifungal. 02:24 They can also have symptoms of arrhythmia. 02:27 Now if they're not on a monitor, they may describe it to you like, I feel like I'm having palpitations or I'm kind of dizzy and I almost even fainted. 02:34 Those are signs that the patient may be having some cardiac arrhythmias. 02:38 Now with severe skin reactions, and we'll talk about allergic reactions, with the skin reactions, you want to think about Stevens-Johnson syndrome. 02:46 That's also called toxic epidermal necrolysis. 02:50 This can be caused by these oral antifungals. 02:53 Also watch for widespread rashes, blistering or peeling of the skin. 02:57 Look at their mouth and their eyes to see if there's mucosal involvement. 03:01 And especially if there's a fever accompanying skin changes, the client needs to know they need to reach out and contact their healthcare provider. 03:09 Now in regards to severe allergic reactions, these can be life-threatening. 03:12 So the patient may experience anaphylaxis. 03:15 They might have angioedema, the swelling of their face, their lips or their tongue. 03:19 That may lead to difficulty breathing and at least they're going to have severe itching. 03:24 So at best, if the patient has any of these symptoms, to keep them the safest, you want them to seek immediate medical attention. 03:32 Now finally, they launch for signs of significant drug interactions. 03:37 Now the symptoms are going to depend on the other medication that it's interacting with. 03:41 Kind of a basic guideline would be with statins, you're going to watch for muscle pain and weakness. 03:47 With benzodiazepines, you're going to look for excessive sedation. 03:50 And with calcium channel blockers, you're looking for hypotension. 03:54 Now that's just a quick review. We went in detail earlier in the series. 03:58 There's some emerging trends in antifungal therapy that all members of the healthcare team need to keep in mind. 04:04 We do have a rising global incidence of fungal infections, but we also have a rising antifungal resistance. 04:10 Now the good news is we've got some novel antifungal agents and they're in development. 04:14 Those are going to target new molecular pathways. 04:17 So that's great news. 04:19 But keep in mind, you may need to use combination therapy if it's a very difficult to treat infection. 04:25 So this underscores the importance of antifungal stewardship and clear programs to accomplish this. 04:32 Remember, we've got some advances in some rapid diagnostic techniques, so stay tuned for those. 04:37 That will improve the time to appropriate treatment, which hopefully will make that more effective. 04:43 If you want to provide clinical excellence in antifungal management, keep these points in mind. 04:49 Make sure the diagnosis is accurate through appropriate testing. 04:53 Make sure the therapy has been selected based on the pathogen, the site, and the patient factors. 04:59 Make sure you've considered special populations and drug interactions, you're monitoring for efficacy and safety, and that you're staying current with the evolving guidelines and emerging resistance patterns. 05:10 Remember, your expertise as a member of the healthcare team makes the difference between treatment success and failure.
