Management of amphotericin-induced phlebitis among HIV patients with cryptococcal meningitis in a resource-limited setting: a prospective cohort study.

ABSTRACT: BACKGROUND:Amphotericin-induced phlebitis is a common infusion-related reaction in patients managed for cryptococcal meningitis. High-quality nursing care is critical component to successful cryptococcosis treatment. We highlight the magnitude and main approaches in the management of amphotericin-induced phlebitis and the challenges faced in resource-limited settings. METHODS:We prospectively determined the incidence of amphotericin-induced phlebitis during clinical trials in Kampala, Uganda from 2013 to 2018. We relate practical strategies and challenges faced in clinical management of phlebitis. RESULTS:Overall, 696 participants were diagnosed with HIV-related cryptococcal meningitis. Participants received 7-14 doses of intravenous (IV) amphotericin B deoxycholate 0.7-1.0?mg/kg/day for induction therapy through peripheral IV lines at a concentration of 0.1?mg/mL in 5% dextrose. Overall, 18% (125/696) developed amphotericin-induced phlebitis. We used four strategies to minimize/prevent the occurrence of phlebitis. First, after every dose of amphotericin, we gave one liter of intravenous normal saline. Second, we rotated IV catheters every three days. Third, we infused IV amphotericin over 4?h. Finally, early ambulation was encouraged to minimize phlebitis. To alleviate phlebitis symptoms, warm compresses were used. In severe cases, treatment included topical diclofenac gel and oral anti-inflammatory medicines. Antibiotics were used only when definite signs of infection developed. Patient/caregivers' education was vital in implementing these management strategies. Major challenges included implementing these interventions in participants with altered mental status and limited access to topical and oral anti-inflammatory medicines in resource-limited settings. CONCLUSIONS:Amphotericin-induced phlebitis is common with amphotericin, yet phlebitis is a preventable complication even in resource-limited settings. TRIAL REGISTRATION:The ASTRO-CM trial was registered prospectively. ClincalTrials.gov : NCT01802385 ; Registration date: March 1, 2013; Last verified: February 14, 2018.

Project description:BACKGROUND:Amphotericin B is the preferred treatment for cryptococcal meningitis, but it has cumulative severe side effects, including nephrotoxicity, hypokalemia, and hypomagnesemia. Amphotericin-induced severe hypokalemia may predispose the patient to cardiac arrhythmias and death, and there is very little data available regarding these toxicities in resource-limited settings. We hypothesized that standardized electrolyte management during amphotericin therapy is essential to minimize toxicity and optimize survival in sub-Saharan Africa. METHODS:Human immunodeficiency virus-infected, antiretroviral therapy naive adults with cryptococcal meningitis were prospectively enrolled at Mulago Hospital in Kampala, Uganda in 3 sequential cohorts with amphotericin B deoxycholate induction treatment. Intravenous fluid use was intermittent in 2001-2002, and universal in 2006-2012. In 2001-2009, serum potassium (K(+)) was monitored on days 1, 7, and 14 of treatment with replacement (K(+), Mg(2+)) per clinician discretion. In 2011-2012, K(+) was measured on days 1, 5, and approximately every 48 hours thereafter with universal electrolyte (K(+), Mg(2+)) supplementation and standardized replacement. Clinical outcomes were retrospectively compared between fluid and electrolyte management strategies. RESULTS:With limited intravenous fluids, the 14-day survival was 49% in 2001-2002. With universal intravenous fluids, the 30-day survival improved to 62% in 2006-2010 (P = .003). In 2011-2012, with universal supplementation of fluids and electrolytes, 30-day cumulative survival improved to 78% (P = .021 vs 2006-2010 cohort). The cumulative incidence of severe hypokalemia (<2.5 mEq/L) decreased from 38% in 2010 to 8.5% in 2011-2012 with universal supplementation (P < .001). CONCLUSIONS:Improved survival was seen in a resource-limited setting with proactive fluid and electrolyte management (K(+), Mg(2+)), as part of comprehensive amphotericin-based cryptococcal therapy.

Project description:BackgroundCryptococcal meningitis (CM) is the most common form of meningitis in Africa. World Health Organization guidelines recommend 14-d amphotericin-based induction therapy; however, this is impractical for many resource-limited settings due to cost and intensive monitoring needs. A cost-effectiveness analysis was performed to guide stakeholders with respect to optimal CM treatment within resource limitations.Methods and findingsWe conducted a decision analysis to estimate the incremental cost-effectiveness ratio (ICER) of six CM induction regimens: fluconazole (800-1,200 mg/d) monotherapy, fluconazole + flucytosine (5FC), short-course amphotericin (7-d) + fluconazole, 14-d of amphotericin alone, amphotericin + fluconazole, and amphotericin + 5FC. We computed actual 2012 healthcare costs in Uganda for medications, supplies, and personnel, and average laboratory costs for three African countries. A systematic review of cryptococcal treatment trials in resource-limited areas summarized 10-wk survival outcomes. We modeled one-year survival based on South African, Ugandan, and Thai CM outcome data, and survival beyond one-year on Ugandan and Thai data. Quality-adjusted life years (QALYs) were determined and used to calculate the cost-effectiveness ratio and ICER. The cost of hospital care ranged from $154 for fluconazole monotherapy to $467 for 14 d of amphotericin + 5FC. Based on 18 studies investigating outcomes for HIV-infected individuals with CM in resource-limited settings, the estimated mean one-year survival was lowest for fluconazole monotherapy, at 40%. The cost-effectiveness ratio ranged from $20 to $44 per QALY. Overall, amphotericin-based regimens had higher costs but better survival. Short-course amphotericin (1 mg/kg/d for 7 d) with fluconazole (1,200 mg/d for14 d) had the best one-year survival (66%) and the most favorable cost-effectiveness ratio, at $20.24/QALY, with an ICER of $15.11 per additional QALY over fluconazole monotherapy. The main limitation of this study is the pooled nature of a systematic review, with a paucity of outcome data with direct comparisons between regimens.ConclusionsShort-course (7-d) amphotericin induction therapy coupled with high-dose (1,200 mg/d) fluconazole is "very cost effective" per World Health Organization criteria and may be a worthy investment for policy-makers seeking cost-effective clinical outcomes. More head-to-head clinical trials are needed on treatments for this neglected tropical disease. Please see later in the article for the Editors' Summary.

Project description:Amphotericin B deoxycholate (AmBd) is the recommended induction treatment for HIV-associated cryptococcal meningitis (CM). Its use is hampered by toxicities that include electrolyte abnormalities, nephrotoxicity, and anemia. Protocols to minimize toxicity are applied inconsistently. In a clinical trial cohort of AmBd-based CM induction treatment, a standardized protocol of preemptive hydration and electrolyte supplementation was applied. Changes in blood counts, electrolyte levels, and creatinine levels over 14 days were analyzed in relation to the AmBd dose, treatment duration (short course of 5 to 7 days or standard course of 14 days), addition of flucytosine (5FC), and outcome. In the 368 patients studied, the hemoglobin levels dropped by a mean of 1.5 g/dl (95% confidence interval [CI], 1.0 to 1.9 g/dl) following 7 days of AmBd and by a mean of 2.3 g/dl (95% CI, 1.1 to 3.6 g/dl) after 14 days. Serum creatinine levels increased by 37 μmol/liter (95% CI, 30 to 45 μmol/liter) by day 7 and by 49 μmol/liter (95% CI, 35 to 64μmol/liter) by day 14 of AmBd treatment. Overall, 33% of patients developed grade III/IV anemia, 5.6% developed grade III hypokalemia, 9.5% had creatinine levels that exceeded 220 μmol, and 6% discontinued AmBd prematurely. The addition of 5FC was associated with a slight increase in anemia but not neutropenia. Laboratory abnormalities stabilized or reversed during the second week in patients on short-course induction. Grade III/IV anemia (adjusted odds ratio [aOR], 2.2; 95% CI, 1.1 to 4.3; P = 0.028) and nephrotoxicity (aOR, 4.5; 95% CI, 1.8 to 11; P = 0.001) were risk factors for 10-week mortality. In summary, routine intravenous saline hydration and preemptive electrolyte replacement during AmBd-based induction regimens for HIV-associated CM minimized the incidence of hypokalemia and nephrotoxicity. Anemia remained a concerning adverse effect. The addition of flucytosine was not associated with increased neutropenia. Shorter AmBd courses were less toxic, with rapid reversibility.
