Abstract Background The evaluation of American cutaneous leishmaniasis (CL) and sporotrichosis (SP) with dermoscopy may improve the diagnosis accuracy and clinical monitoring. Objectives To describe the dermoscopic findings and patterns of skin lesions of patients with CL and SP followed up at the Laboratory of Clinical Research and Surveillance in Leishmaniasis (LaPClinVigiLeish), Evandro Chagas National Institute of Infectious Diseases (INI), Oswaldo Cruz Foundation, Rio de Janeiro, Brazil. Methods The authors included patients with a diagnosis of CL or SP, who attended at INI/ Fiocruz, between 2019‒2021. All patients had 3 dermoscopic examinations (DermLite DL4): before treatment (T0), during treatment (T1), and after healing (T2). Up to three lesions per patient were evaluated. Results The authors studied 47 patients with CL (74 lesions), and 19 patients with SP (24 lesions). The authors described dermoscopic structures such as rosettes, white lines, white dots, brown focal structureless areas, brown lines and dots, white perilesional circles, perilesional hyperchromic circles, microulcerations and the rainbow patterns. The authors created specific patterns; in CL: CL-T0 “central yellow scales with a white perilesional circle pattern”, CL-T1 “diffuse structureless white area pattern” and CL-T2 “white and brown focal structureless areas pattern”. In SP: SP-T0 the “pustule with erythema pattern”; SP-T1 the “focal structureless white areas with erythema pattern” and SP-T2 the “white linear pattern”. Study limitations This study does not correlate dermoscopic findings with time of disease evolution at the first medical examination. Conclusions The recognition of CL and SP dermoscopy patterns may be helpful tool for the differential diagnosis and monitoring of disease evolution.

Abstract Genital lesions are an unusual presentation of American cutaneous leishmaniasis. Conditions such as disseminated cutaneous leishmaniasis and HIV infection may be associated with genital involvement. The authors present five cases of American cutaneous leishmaniasis with genital lesions and discuss the clinical and epidemiological aspects observed in this case series.

Abstract In Brazil, meglumine antimoniate is the first drug of choice for mucosal leishmaniasis treatment followed by amphotericin B and pentamidine isethionate. We report the case of a patient with severe mucosal lesions caused by Leishmania (Viannia) braziliensis that were difficult to treat. Over a 14-year period, the patient showed low adherence and three treatment attempts with meglumine antimoniate failed. Additionally, there was an unsatisfactory response to liposomal amphotericin B and nephrotoxicity when using amphotericin B deoxycholate that persisted after new treatment attempt with liposomal amphotericin B. Finally, healing was achieved with pentamidine isethionate and maintained during nine months of monitoring.

Abstract INTRODUCTION: Favorable responses in American tegumentary leishmaniasis (ATL) patients to treatment with 5 mg Sbv/kg/day meglumine antimoniate (MA) has been reported in Rio de Janeiro, but little is known regarding the therapeutic response to low doses in patients from other locations. METHODS: A retrospective review of medical records was conducted to compare the therapeutic response to 5 mg Sbv/kg/day MA treatment among 36 patients who acquired ATL in Brazilian states other than Rio de Janeiro (OS group) and 72 patients from Rio de Janeiro (RJ group). RESULTS: One course of 5 mg Sbv/kg/day MA cured 72.8% of 81 cutaneous (CL) and 66.6% of 27 mucosal (ML) leishmaniasis-infected patients: 70% in the CL/RJ group, 81% in the CL/OS group, 50% in the ML/RJ group, and 80% in the ML/OS group. After up to two additional treatment courses at the same dose, 88.9% and 85.2% of the CL and ML patients were cured, respectively. Adverse events were observed in 40% of patients in the CL/RJ group, 57% of the CL/OS group, 58% of the ML/RJ group, and 80% of the ML/OS group. No significant differences were observed in the cure rates or adverse effects between the RJ and OS groups. No patients required permanent discontinuation of treatment due to adverse events. CONCLUSIONS: Patients with ATL acquired in both RJ and OS may respond to low-dose MA. While high-dose MA should remain the standard treatment for ATL, low-dose MA might be preferred when toxicity is a primary concern.

BACKGROUND American tegumentary leishmaniasis (ATL) is a non-lethal parasitic disease that presents with cutaneous (CL) and mucosal (ML) clinical forms. ATL treatment aims at healing the lesions and preventing the development of the late mucosal form. Systemic meglumine antimoniate (MA) therapy with 10-20 mg Sb5+/kg/day is the first choice of treatment. However, alternative therapies using 5 mg Sb5+/kg/day or intralesional (IL) MA are the usual regimens at the National Institute of Infectious Diseases (NIID), Rio de Janeiro, Brazil. OBJECTIVES To evaluate lethality and the incidence of relapse and development of late ML in CL patients treated at NIID from 2001 until 2013. METHODS Data were recovered from records of all ATL patients diagnosed during that period. FINDINGS Out of 777 patients, 753 were treated with MA (96.9%). Of those, 89.1% received alternative therapy of 9.9% IL and 79.2% systemic 5 mg Sb5+/kg/day. Some patients required 1-3 additional courses of treatment, thus making a total of 997 courses; 85.2% of them were subjected to alternative therapies. Lethality was 0.1%, relapse incidence 5.8%, and late ML incidence 0.25%. As a final outcome for the 777 patients, 95.9% were cured, 0.1% died and 4.0% were not able to follow-up. MAIN CONCLUSIONS Alternative MA schedules resulted in low lethality without increase of relapse or late ML incidence.

ABSTRACT Background Atypical presentations of cutaneous leishmaniasis include sporotrichoid leishmaniasis (SL), which is clinically described as a primary ulcer combined with lymphangitis and nodules and/or ulcerated lesions along its pathway. Aims To assess the differences between patients with sporotrichoid leishmaniasis and typical cutaneous leishmaniasis (CL). Methods From January 2004 to December 2010, 23 cases of SL (4.7%) were detected among 494 CL patients diagnosed at a reference center for the disease in Rio de Janeiro State, Brazil. These 23 cases were compared with the remaining 471 patients presenting CL. Results SL predominated in female patients (60.9%, p = 0.024), with older age (p = 0.032) and with lesions in upper limbs (52.2%, p = 0.028). CL affected more men (64.5%), at younger age, and with a higher number of lesions exclusively in lower limbs (34.8%). Conclusions Differences in clinical and epidemiological presentation were found between SL patients as compared to CL ones, in a region with a known predominance of Leishmania (Viannia) braziliensis. The results are similar to the features of most of the sporotrichosis patients as described in literature, making the differential diagnosis between ATL and sporotrichosis more important in overlapping areas for both diseases, like in Rio de Janeiro State.

SUMMARY American tegumentary leishmaniasis is an infectious disease caused by a protozoan of the genus Leishmania. Pentavalent antimonials are the first choice drugs for cutaneous leishmaniasis (CL), although doses are controversial. In a clinical trial for CL we investigated the occurrence of pancreatic toxicity with different schedules of treatment with meglumine antimoniate (MA). Seventy-two patients were allocated in two different therapeutic groups: 20 or 5 mg of pentavalent antimony (Sb5+)/kg/day for 20 or 30 days, respectively. Looking for adverse effects, patients were asked about abdominal pain, nausea, vomiting or anorexia in each medical visit. We performed physical examinations and collected blood to evaluate serum amylase and lipase in the pre-treatment period, and every 10 days during treatment and one month post-treatment. Hyperlipasemia occurred in 54.8% and hyperamylasemia in 19.4% patients. Patients treated with MA 20 mg Sb5+ presented a higher risk of hyperlipasemia (p = 0.023). Besides, higher MA doses were associated with a 2.05 higher risk ratio (p = 0.003) of developing more serious (moderate to severe) hyperlipasemia. The attributable fraction was 51% in this group. Thirty-six patients presented abdominal pain, nausea, vomiting or anorexia but only 47.2% of those had hyperlipasemia and/ or hyperamylasemia. These findings suggest the importance of the search for less toxic therapeutic regimens for the treatment of CL.

Introdução: Antimoniais pentavalentes são os fármacos de primeira escolha no tratamento da leishmaniose tegumentar. Dados de ototoxicidade relacionados a tais fármacos são escassos na literatura, o que nos levou a desenvolver um estudo de funções cócleo-vestibulares. Relato de caso: Relatamos caso de paciente masculino de 78 anos com leishmaniose tegumentar, que apresentou aumento significativo dos limiares auditivos com zumbido e tontura rotatória grave durante o tratamento com antimoniato de meglumina. Os sintomas pioraram até duas semanas após a interrupção do tratamento. Conclusão: Tontura e zumbido já tinham sido associados ao antimoniato de meglumina. Entretanto, este é o primeiro caso bem documentado de toxicidade cócleo-vestibular relacionado ao antimoniato de meglumina.

Introduction: Pentavalent antimonials are the first drug of choice in the treatment of tegumentary leishmaniasis. Data on ototoxicity related with such drugs is scarcely available in literature, leading us to develop a study on cochleovestibular functions. Case Report: A case of a tegumentary leishmaniasis patient, a 78-year-old man who presented a substantial increase in auditory threshold with tinnitus and severe rotatory dizziness during the treatment with meglumine antimoniate, is reported. These symptoms worsened in two weeks after treatment was interrupted. Conclusion: Dizziness and tinnitus had already been related to meglumine antimoniate. However, this is the first well documented case of cochlear-vestibular toxicity related to meglumine antimoniate.

Relatamos caso de paciente de 42 anos atendida em centro de referência em leishmanioses no Rio de Janeiro, Brasil, apresentando lesão de leishmaniose cutânea no antebraço direito. Iniciado tratamento com baixa dose de antimoniato de meglumina (AM) intramuscular (5 mg Sb5+/kg/dia), houve melhora após 28 dias, porém com desenvolvimento de eczema generalizado. Após 87 dias, notou-se piora da lesão. A paciente recusou o tratamento com anfotericina B. Infiltrou-se AM na lesão em duas sessões, resultando em eczema local com bolhas. Entretanto, 20 dias depois, tanto a úlcera quanto o eczema regrediram. A administração intralesional do AM deve ser utilizada com cautela em pacientes com hipersensibilidade cutânea a este fármaco.

We report a case of a 42 year-old female, who came to a leishmaniasis reference center in Rio de Janeiro, Brazil, presenting a cutaneous leishmaniasis lesion in the right forearm. Treatment with low-dose intramuscular meglumine antimoniate (MA) (5 mg Sb5+/kg/day) was initiated, with improvement after 28 days, although with the development of generalized eczema. After 87 days, the lesion worsened. Patient refused treatment with amphotericin B. MA was then infiltrated in the lesion, in two sessions, resulting in local eczema, with bullae formation; however, twenty days after, both the ulcer and eczema receded. Intralesional administration of MA should be used carefully when previous cutaneous hypersensitivity is detected.

Apesar da alta prevalência entre idosos, a perda auditiva é pouco investigada. A audiometria é o teste padrão ouro para avaliação de perda auditiva, mas sua realização em larga escala traz dificuldades operacionais. O auto-relato pode ser uma alternativa. OBJETIVO: Determinar se uma única questão genérica tem validade para ser utilizada em pesquisas epidemiológicas. FORMA DE ESTUDO:Revisão sistemática. MATERIAL E MÉTODO: Foi realizada uma pesquisa da literatura médica nas bases de dados MEDLINE e LILACS, no período de 1990 a 2004. Foram analisados também artigos citados nas referências dos artigos identificados na busca eletrônica. Foram selecionados os artigos que compararam os resultados obtidos através de auto-relato, por meio de uma questão única genérica, e da audiometria tonal. Foram extraídos os dados de prevalência da perda auditiva, e de sensibilidade, especificidade e valores preditivos. RESULTADO: Foram incluídos dez estudos transversais. A questão única genérica parece ser um indicador aceitável de perda auditiva, sensível e razoavelmente específico, principalmente quando a perda é identificada como sendo a média tonal que inclua freqüências até 2 ou 4 kHz, a um nível de 40 dBNA, na melhor orelha. CONCLUSÃO: Uma questão única genérica tem uma boa performance em identificar idosos com perda auditiva e pode, portanto, ser recomendada para um estudo epidemiológico que não possa realizar medidas audiométricas.

Despite its high prevalence in the aged, hearing loss has been poorly investigated. Audiometry is the gold standard for evaluation of hearing loss, but large-scale use of the procedure involves operational difficulties. Thus, self-report may be an alternative. AIM: To determine if a single global question is valid for use in epidemiologic research. STUDY DESIGN: Systematic review. MATERIAL AND METHOD: A search of the medical literature from 1990 to 2004 was performed using MEDLINE and LILACS. The references of the articles identified in the electronic search were also reviewed. STUDY SELECTION AND DATA EXTRACTION: The articles that compared the results obtained with self-report to a single global question with those obtained by pure tone audiometry were selected. Data about the prevalence of hearing loss, and sensitivity, specificity and predictive values were extracted. DATA SYNTHESIS: Ten longitudinal studies were included. A single global question seems to be an acceptable indicator of hearing loss, sensitive and reasonably specific, mainly if the hearing loss is identified as the tone average that includes frequencies up to 2 or 4 kHz, at 40 dBHL level, in the best ear. CONCLUSION: A single global question shows good performance in identifying older persons with hearing loss and can be recommended for an epidemiologic study if audiometric measurements cannot be performed.
