ABSTRACT

Abstract INTRODUCTION: Visceral leishmaniasis (VL) is fatal if not diagnosed and treated. This study aimed to estimate the cost-effectiveness of diagnostic-therapeutic alternatives for VL in Brazil. METHODS: A decision model estimated the life expectancy and costs of six diagnostic-therapeutic strategies. RESULTS: IT LEISH + liposomal amphotericin B emerged the best option, presenting lower costs and higher effectiveness. DAT-LPC + liposomal amphotericin B showed an incremental cost-effectiveness ratio of US$ 326.31 per life year. CONCLUSIONS: These findings indicate the feasibility of incorporating DAT and designating liposomal amphotericin B as the first-line drug for VL in Brazil.

ABSTRACT

Abstract INTRODUCTION: The drugs available for visceral leishmaniasis (VL) treatment in Brazil have specific characteristics in terms of operability, effectiveness, toxicity, and cost. The aim of this study was to estimate the direct costs of therapies recommended by the Ministry of Health (MH) for VL treatment in Brazil. METHODS: The analytical perspective used was that adopted by the Brazilian Public Health System. Three drugs and four regimens were included: 1) N-methyl glucamine antimoniate intramuscularly at 20mg per kg per day for 30 days; 2) N-methyl glucamine antimoniate intravenously at 20mg per kg per day for 30 days; 3) amphotericin B deoxycholate at 1mg per kg per day for 21 days; and 4) liposomal amphotericin B at 3mg per kg per day for a 7 days treatment. RESULTS: The estimated direct costs of treatment for an adult patient using N-methylglucamine antimoniate administered via the intramuscular and intravenous routes were USD 418.52 and USD 669.40, respectively. The estimated cost of treatment with amphotericin B deoxycholate was USD 1,522.70. Finally, the estimated costs of treatment with liposomal amphotericin B were USD 659.79, and USD 11,559.15 using the price adopted by the WHO and the Drug Regulation Board, respectively. CONCLUSIONS: This analysis indicates the economic feasibility of replacing N-methyl glucamine antimoniate with liposomal amphotericin B, which allows a shorter treatment period with less toxicity compared with other treatments, provided that the purchase value used by the WHO and transferred to the MH is maintained.

ABSTRACT

Abstract: The aim of the present study was to estimate the financial costs of the incorporation and/or replacement of diagnostic tests for human visceral leishmaniasis (VL) in Brazil. The analysis was conducted from the perspective of the Brazilian Unified National Health System (SUS) over a period of three years. Six diagnostic tests were evaluated: the indirect immunofluorescence antibody test (IFAT), the IT LEISH rapid test, the parasitological examination of bone marrow aspirate, the direct agglutination test (DAT-LPC) standardized in the Clinical Research Laboratory, René Rachou Institute of the Oswaldo Cruz Foundation, the Kalazar Detect rapid test, and polymerase chain reaction (PCR). The assumptions used were the number of suspected cases of VL reported to the Brazilian Ministry of Health in 2014 and the direct cost of diagnostic tests. The costs to diagnose suspected cases of VL over three years using the IFAT and the DAT-LPC were estimated at USD 280,979.91 and USD 121,371.48, respectively. The analysis indicated that compared with the use of the IFAT, the incorporation of the DAT-LPC into the SUS would result in savings of USD 159,608.43. With regard to the budgetary impact of rapid tests, the use of IT LEISH resulted in savings of USD 21.708,72 over three years. Compared with a parasitological examination, diagnosis using PCR resulted in savings of USD 3,125,068.92 over three years. In this study, the replacement of the IFAT with the DAT-LPC proved financially advantageous. In addition, the replacement of the Kalazar Detect rapid test with the IT LEISH in 2015 was economically valuable, and the replacement of parasitological examination with PCR was indicated.


Resumo: O estudo teve como objetivo estimar os custos financeiros da incorporação e/ou substituição dos testes diagnósticos para a leishmaniose visceral (LV) humana no Brasil. A análise foi realizada na perspectiva do Sistema Único de Saúde (SUS) ao longo de três anos. Foram avaliados seis testes diagnósticos: reação de imunofluorescência indireta (RIFI), teste rápido IT LEISH, exame parasitológico de aspirado de medula óssea, teste de aglutinação direta DAT-LPC padronizado pelo Laboratório de Pesquisas Clínicas do Instituto René Rachou, Fundação Oswaldo Cruz, teste rápido Kalazar Detect e reação em cadeia da polimerase (PCR). Os parâmetros utilizados foram o número de casos suspeitos de LV notificados ao Ministério da Saúde em 2014 e o custo direto dos testes diagnósticos. Os custos do diagnóstico de casos suspeitos de LV ao longo de três anos usando o RIFI e DAT-LPC foram estimados em USD 280.979,91 e USD 121.371,48, respectivamente. De acordo com a análise, comparado ao uso do RIFI, a incorporação do DAT-LPC pelo SUS resultaria numa economia de USD 159.608,43. Com relação ao impacto dos testes rápidos, o uso do IT LEISH resultou em economia de USD 21.708,72 ao longo de três anos. Comparado ao exame parasitológico, o diagnóstico com PCR resultou em economia de USD 3.125.068,92 ao longo de três anos. Neste estudo, a substituição do RIFI pelo DAT-LPC mostrou ser financeiramente vantajosa. Além disso, a substituição do teste rápido Kalazar Detect com o IT LEISH em 2015 foi economicamente apropriada, e a substituição do exame parasitológico pela PCR está economicamente indicada.
