Assessment of the antileishmanial activity of diallyl sulfide combined with meglumine antimoniate on Leishmania major: Molecular docking, in vitro, and animal model. PLoS One 2024; 19:e0307537. [PMID: 39213335 PMCID: PMC11364230 DOI: 10.1371/journal.pone.0307537] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Accepted: 07/07/2024] [Indexed: 09/04/2024] Open
Abstract
Currently, no safe vaccine against leishmaniasis is available. So far, different control strategies against numerous reservoir hosts and biological vectors have not been environment-friendly and feasible. Hence, employing medicinal components and conventional drugs could be a promising approach to developing novel therapeutic alternatives. This study aimed to explore diallyl sulfide (DAS), a dynamic constituent of garlic, alone and in a mixture with meglumine antimoniate (MAT as standard drug) using in vitro and animal model experiments against Leishmania major stages. The binding affinity of DAS and four major defense elements of the immune system (iNOS, IFN-ɣ, IL-12, and TNF-α) was used to predict the predominant binding mode for molecular docking configurations. Herein, we conducted a broad range of experiments to monitor and assess DAS and MAT potential treatment outcomes. DAS, combined with MAT, displayed no cytotoxicity and employed a powerful anti-leishmanial activity, notably against the clinical stage. The function mechanism involved immunomodulation through the induction of Th1 cytokine phenotypes, triggering a high apoptotic profile, reactive oxygen species (ROS) production, and antioxidant enzymes. This combination significantly decreased cutaneous lesion diameter and parasite load in BALB/c mice. The histopathological findings performed the infiltration of inflammatory cells associated with T-lymphocytes, particularly CD4+ phenotypes, as determined by biochemical markers in alleviating the amastigote stage and improving the pathological changes in L. major infected BALB/c mice. Therefore, DAS and MAT deserve further advanced therapeutic development and should be considered as possible candidates for treating volunteer cases with cutaneous leishmaniasis in designing an upcoming clinical trial.

Doni NY, An İ. Geriatric cutaneous leishmaniasis: a retrospective analysis of 622 cases. Postgrad Med J 2024; 100:666-670. [PMID: 38598958 DOI: 10.1093/postmj/qgae048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Revised: 03/10/2024] [Accepted: 03/22/2024] [Indexed: 04/12/2024]
Abstract
BACKGROUND Cutaneous leishmaniasis (CL) is most common in childhood because children are exposed to the parasite early and, unlike adults, do not have immunity to CL. Since CL is less common in geriatric patients, clinical and epidemiological data in this age group are limited. This study aims to compare the clinical and demographic characteristics of geriatric patients diagnosed with CL with young patients. METHODS In this retrospective study, 622 patients aged 65 and over and 6350 patients aged 19-64, who applied to Şanlıurfa Oriental Boil Diagnosis and Treatment Center between January 2013 and February 2024 and were diagnosed with CL by parasitological examination, were included. Clinical and demographic characteristics of patients diagnosed with CL, such as age, gender, location of the lesion, lesion size, duration of the lesion, and treatments applied due to the diagnosis of CL, were recorded. Clinical and demographic characteristics of geriatric and young patients were compared. RESULTS The mean age of elderly CL cases was 72.95 ± 6.54 years, and 65.2% were female. The most common clinical forms were ulcers (51.9%) and plaques (41%), respectively, in young and elderly patients. The most common locations of the lesions were upper limbs (54.8%) in all patients. The most preferred treatment method was intralesional (IL) meglumine antimoniate (MA) treatment (98.3%) in all patients. There were no difference between young and elderly CL cases in terms of mean number of lesions, average lesion duration, average lesion size, lesion location, clinical forms of lesions, and treatments options (P > 0.05). CONCLUSIONS Based on the results of our study, it can be said that the clinical and demographic characteristics of CL are similar in young and old patients and systemic MA treatment shows similar clinical benefit in both age groups. In addition, it can be said that systemic MA therapy can be used safely in young patients and elderly patients without contraindications. IL MA therapy can be used in elderly patients where systemic MA therapy is contraindicated.

Investigating the Effect of Satureja khuzestanica Essential oil on MDR1 Gene Expression in Leishmania major. Acta Parasitol 2024; 69:526-532.

Abstract
BACKGROUND Cutaneous leishmaniasis is among the neglected diseases in the world. Pentavalent antimonial compounds are considered the first-line treatment for this disease. However, using alternative natural products has received great attention due to the side effects of chemical drugs and drug resistance of the Leishmania parasite. The present study aims to investigate the effect of Satureja khuzestanica essential oil (SKEO) on MDR1 gene expression. METHODS In this study, standard strains of Leishmania major promastigotes were exposed to 5, 10, 15, and 20 µg/ml of SKEO. MDR1 gene expression of parasites exposed to essential oil was evaluated using real-time PCR. GAPDH was employed as the housekeeping gene for internal control. RESULTS Despite the increase, no statistically significant difference was observed in the relative expression of the MDR1 gene between the control group and the groups containing 5, 10, and 20 µg/ml of SKEO (P > 0.05). The relative expression of the MDR1 gene significantly increased in the group containing 15 μg/ml of essential oil compared to the control one (P < 0.05). CONCLUSION This study showed that the use of essential oil of Satureja khuzestanica plant can have an increasing effect on the expression of MDR1 gene of Leishmania promastigotes, which is the best case if Satureja khuzestanica essential oil reduces the expression of MDR1 gene. So it seems that the use of essential oil of Satoria plant is effective in controlling Leishmania parasite, but its concentrations induce drug resistance. As a result, concentrations of essential oil should be used that have a controlling effect on the growth and proliferation of Leishmania parasite and also have the least effect on the induction of MDR1 gene expression.

Abstract
OBJECTIVE To determine whether a combination of a single intramuscular (IM) dose of pentamidine (7 mg/kg) followed by oral tamoxifen 40 mg/day for 20 days is non-inferior to three IM doses of pentamidine 7 mg/kg in the treatment of cutaneous leishmaniasis with a margin of 15%. METHODS Phase II, randomised, controlled, open-label, non-inferiority clinical trial. Primary outcome was the complete healing of the lesions 6 months after starting treatment. Secondary outcomes were healing 3 months after starting treatment and determining the presence and severity of adverse effects (AE). RESULTS The research was concluded with 49 patients; Leishmania (Viannia) guyanensis was the most frequent species isolated. In the primary outcome, 18 (72%) (95% CI: 52.4%-85.7%) of the 25 patients allocated to the intervention group and 24 (100%) (95% CI: 86.2%-100%) of the control group (p = 0.015) met the established criteria of cure. There was no AE with tamoxifen. CONCLUSION Although a 72% cure rate presented by the combination of tamoxifen and pentamidine was lower than in the control group that achieved a 100% cure, it is still a safe and is a clinically relevant result. It indicates that the therapeutic scheme evaluated may be a promising option for populations in remote areas, however it should be further studied, in order to include a larger number of patients.

Abstract
Leishmaniasis is a neglected tropical disease endemic primarily to low- and middle-income countries, for which there has been inadequate development of affordable, safe, and efficacious therapies. Clinical manifestations of leishmaniasis range from self-healing skin lesions to lethal visceral infection with chances of relapse. Although treatments are available, secondary effects limit their use outside the clinic and negatively impact the quality of life of patients in endemic areas. Other non-medicinal treatments, such as thermotherapies, are limited to use in patients with cutaneous leishmaniasis but not with visceral infection. Recent studies shed light to mechanisms through which Leishmania can persist by hiding in cellular safe havens, even after chemotherapies. This review focuses on exploring the cellular niches that Leishmania parasites may be leveraging to persist within the host. Also, the cellular, metabolic, and molecular implications of Leishmania infection and how those could be targeted for therapeutic purposes are discussed. Other therapies, such as those developed against cancer or for manipulation of the ferroptosis pathway, are proposed as possible treatments against leishmaniasis due to their mechanisms of action. In particular, treatments that target hematopoietic stem cells and monocytes, which have recently been found to be necessary components to sustain the infection and provide a safe niche for the parasites are discussed in this review as potential field-deployable treatments against leishmaniasis.

Abstract
BACKGROUND Pentoxifylline was initially marketed for use in patients with intermittent claudication due to chronic occlusive arterial disease of the extremities but has since been shown to have several off-label uses in dermatology. AIMS The aim of this review is to increase awareness of the several applications of pentoxifylline in the field of dermatology. METHODS A comprehensive PubMed search was conducted in May 2022 using the following phrases "dermatology" AND "pentoxifylline." Our search period spanned 34 years from 1988 to 2022. All available literature was reviewed. Reference lists of identified articles were included. Studies were excluded if they were not in English and if the study was out of scope. Eighty-one articles were included in this review. RESULTS Pentoxifylline has been used to treat various dermatological conditions including peripheral vascular disease, vasculitis and vasculopathies, chilblains, pigmented purpuric dermatosis, granuloma annulare, necrobiosis, keloids, lichen sclerosis et atrophicus, scars, radiation-induced fibrosis, vitiligo, alopecia areata, leishmaniasis, and leprosy. CONCLUSIONS Pentoxifylline's use in dermatology is growing. However, there are limited larger studies and randomized control trials on the use of pentoxifylline in dermatology and more investigation is needed to evaluate its use for many dermatologic conditions. Pentoxifylline's unique mechanism of action as well as its good tolerability, cost-effectiveness, and minimal drug interactions make it a convenient primary or adjunctive option in many dermatological conditions.

Abstract
INTRODUCTION Various interventions including laser therapy, heat therapy, and several drugs have been trialed in patients with cutaneous leishmaniasis. Due to the lack of an evidence-based comparison of all these interventions, we carried out the present network meta-analysis. METHODS Electronic databases were searched for randomized clinical trials evaluating the efficacy and safety of any interventions in patients with cutaneous leishmaniasis. The proportion of patients with complete cure was the primary outcome. The proportion of lesions cured at the end of treatment, the proportion of lesions with minimal/no response to treatment, and proportion of wounds with minimal/no change were the secondary outcomes. Random-effects modeling was used for generating pooled estimates. Rankogram plot was used for identifying the 'best intervention'. For interventions containing a combination of treatments, backslash (/) has been used for depicting the same. RESULTS One-hundred and thirty-one studies were included. Intralesional meglumine, topical paromomycin/gentamicin, topical paromomycin, parenteral sodium stibogluconate, topical honey/intralesional meglumine, topical liposomal amphotericin B, oral zinc sulphate, oral miltefosine, parenteral meglumine, heat therapy, topical liposomal azithromycin, intralesional meglumine/silver dressing, intralesional sodium stibogluconate, parenteral meglumine/intralesional meglumine, oral allopurinol/parenteral meglumine, topical trichloroacetic acid/heat therapy, oral zinc sulphate/oral ketoconazole, topical imiquimod/cryotherapy, intralesional meglumine/cryotherapy, topical herbal extract of Z-HE, parenteral pentamidine, topical trichloroacetic acid/intralesional meglumine, carbon-dioxide laser, topical recombinant granulocyte-macrophage colony-stimulating factor/parenteral meglumine, intralesional dapsone, carbon-dioxide laser/intralesional meglumine, moist wet dressing with sodium hypochlorite, parenteral sodium stibogluconate/intralesional recombinant granulocyte-macrophage colony-stimulating factor, oral dapsone, intralesional sodium stibogluconate/oral ketoconazole, intralesional sodium stibogluconate/parenteral sodium stibogluconate and electrocautery/moist wet dressing with sodium hypochlorite were observed with significantly greater proportion of patients with complete cure compared to placebo/untreated controls. Rankogram analysis revealed that parenteral pentamidine has the highest statistical probability of being the best in the pool. CONCLUSION We observed several interventions to be effective for treating cutaneous leishmaniasis. However, greater caution is required in interpreting the results as the estimates are likely to change with the advent of results from future studies.

Abstract
BACKGROUND The current scenario and position of laser and light-based therapies (LLBT) in the therapeutic rosacea scheme are lacking evidence-based recommendations and comparisons on efficacy and tolerability among different devices. This article aimed to systematically compare the efficacy, acceptability, and tolerability of the pulsed dye laser (PDL) versus other devices. METHOD A literature search was conducted in March 2020. Four domains were analyzed throughout the following six outcomes: Spectrophotometer erythema index and percentage of reduction for background erythema, telangiectasia grading scale for telangiectasias, visual analog scale for pain, and physician's assessment and patient's satisfaction for treatment success. RESULTS Our search yielded 423 potentially relevant studies. After removing the excluded and duplicated records, 12 records were assessed for eligibility in the meta-analysis. Erythema (RR:0.38 95%CI: -0.20-0.95), telangiectasias (RR:0.54 95%CI: -0.87-1.94), and the treatment success throughout the physician's assessment (RR:1.23 95%CI: 0.74-2.04) and the patient's satisfaction (RR:1.15 95%CI: 0.73-1.82) were not significantly different between pulsed dye laser and other LLBT. In the pain domain, PDL was as painful as other LLBT (RR:-0.23 95%CI: -0.96-0.49) but more painful than neodymium: yttrium-aluminum-garnet laser (RR:0.84 95%CI: 0.53-1.14) and less than intense pulsed light (RR:-1.18 95%CI: -1.56-0.80). CONCLUSION This work based on previously published literature demonstrates that the quality of evidence to support any recommendation on LLBT in rosacea is low-to-moderate. Among all the available devices, PDL holds the most robust evidence, although in the meta-analysis the effectiveness was comparable to other LLBT, such as neodymium: yttrium-aluminum-garnet laser (Nd-YAG) or IPL.

Efficacy of imiquimod 5% cream as first-line management in cutaneous leishmaniasis caused by Leishmania mexicana. Rev Soc Bras Med Trop 2021; 54:e0305-2020.

Abstract
Cutaneous leishmaniasis (CL) involves several differential diagnoses as it lacks a gold standard diagnostic test. Its diagnosis is easier in endemic regions; however, many cases come from travelers to endemic areas. A 22-year-old patient, who had recently visited Oaxaca, Mexico, developed two asymptomatic ulcers weeks later on the left auricle and the nose. Leishmania mexicana was identified using polymerase chain reaction. The patient was treated with imiquimod 5% cream three times/week, providing favorable results after 12 weeks, without relapse 2 months after therapy. To our knowledge, this is the first case of CL due to L. mexicana effectively treated with imiquimod.

Development of new combination anti-leishmanial complexes: Triphenyl Sb(V) mono-hydroxy mono-quinolinolates. J Inorg Biochem 2021; 219:111385. [PMID: 33894637 DOI: 10.1016/j.jinorgbio.2021.111385] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Revised: 01/20/2021] [Accepted: 01/27/2021] [Indexed: 12/18/2022]
Abstract
In seeking to develop single entity combination anti-Leishmanial complexes six heteropletic organometallic Sb(V) hydroxido quinolinolate complexes of general formula [SbPh3(C9H4NORR')(OH)] have been synthesised and characterised, derived from a series of halide substituted quinolinols (8-hydroxyquinolines). Single crystal X-ray diffraction on all the complexes show a common distorted six-coordinate octahedral environment at the Sb(V) centre, with the aryl groups and nitrogen atom of quinolinolate ligand bonding in the equatorial planes, with the two oxygen atoms (hydroxyl and quinolinolate) occupying the axial plane in an almost linear configuration. Each complex was tested for their anti-promastigote activity and mammalian cytotoxicity and a selectivity indices established. The complexes displayed excellent anti-promastigote activity (IC50: 2.03-3.39 μM) and varied mammalian cytotoxicity (IC50: 12.7-46.9 μM), leading to a selectivity index range of 4.52-16.7. All complexes displayed excellent anti-amastigote activity with a percentage infection range of 2.25%-9.00%. All complexes performed substantially better than the parent quinolinols and comparable carboxylate complexes [SbPh3(O2CRR')2] indicating the synergistic role of the Sb(V) and quinolinol moieties in increasing parasite mortality. Two of the complexes [SbPh3(C9H4NOBr2)(OH)] 4, [SbPh3(C9H4NOI2)(OH)] 5, provide an ideal combination of high selective and good activity towards the leishmanial amastigotes and offer the potential as good lead compounds.
