Abstract
BACKGROUND Treatment for post-kala-azar dermal leishmaniasis (PKDL) in Sudan is currently recommended only for patients with persistent or severe disease, mainly because of the limitations of current therapies, namely toxicity and long hospitalization. We assessed the safety and efficacy of miltefosine combined with paromomycin and liposomal amphotericin B (LAmB) for the treatment of PKDL in Sudan. METHODOLOGY/PRINCIPAL FINDINGS An open-label, phase II, randomized, parallel-arm, non-comparative trial was conducted in patients with persistent (stable or progressive disease for ≥ 6 months) or grade 3 PKDL, aged 6 to ≤ 60 years in Sudan. The median age was 9.0 years (IQR 7.0-10.0y) and 87% of patients were ≤12 years old. Patients were randomly assigned to either daily intra-muscular paromomycin (20mg/kg, 14 days) plus oral miltefosine (allometric dose, 42 days)-PM/MF-or LAmB (total dose of 20mg/kg, administered in four injections in week one) and oral miltefosine (allometric dose, 28 days)-LAmB/MF. The primary endpoint was a definitive cure at 12 months after treatment onset, defined as clinical cure (100% lesion resolution) and no additional PKDL treatment between end of therapy and 12-month follow-up assessment. 104/110 patients completed the trial. Definitive cure at 12 months was achieved in 54/55 (98.2%, 95% CI 90.3-100) and 44/55 (80.0%, 95% CI 70.2-91.9) of patients in the PM/MF and AmB/MF arms, respectively, in the mITT set (all randomized patients receiving at least one dose of treatment; in case of error of treatment allocation, the actual treatment received was used in the analysis). No SAEs or deaths were reported, and most AEs were mild or moderate. At least one adverse drug reaction (ADR) was reported in 13/55 (23.6%) patients in PM/MF arm and 28/55 (50.9%) in LAmB/MF arm, the most frequent being miltefosine-related vomiting and nausea, and LAmB-related hypokalaemia; no ocular or auditory ADRs were reported. CONCLUSIONS/SIGNIFICANCE The PM/MF regimen requires shorter hospitalization than the currently recommended 60-90-day treatment, and is safe and highly efficacious, even for patients with moderate and severe PKDL. It can be administered at primary health care facilities, with LAmB/MF as a good alternative. For future VL elimination, we need new, safe oral therapies for all patients with PKDL.

Abstract
BACKGROUND This study aimed to determine whether paromomycin plus miltefosine (PM/MF) is noninferior to sodium stibogluconate plus paromomycin (SSG/PM) for treatment of primary visceral leishmaniasis in eastern Africa. METHODS An open-label, phase 3, randomized, controlled trial was conducted in adult and pediatric patients at 7 sites in eastern Africa. Patients were randomly assigned to either 20 mg/kg paromomycin plus allometric dose of miltefosine (14 days), or 20 mg/kg sodium stibogluconate plus 15 mg/kg paromomycin (17 days). The primary endpoint was definitive cure after 6 months. RESULTS Of 439 randomized patients, 424 completed the trial. Definitive cure at 6 months was 91.2% (155 of 170) and 91.8% (156 of 170) in the PM/MF and SSG/PM arms in primary efficacy modified intention-to-treat analysis (difference, 0.6%; 97.5% confidence interval [CI], -6.2 to 7.4), narrowly missing the noninferiority margin of 7%. In the per-protocol analysis, efficacy was 92% (149 of 162) and 91.7% (155 of 169) in the PM/MF and SSG/PM arms (difference, -0.3%; 97.5% CI, -7.0 to 6.5), demonstrating noninferiority. Treatments were well tolerated. Four of 18 serious adverse events were study drug-related, and 1 death was SSG-related. Allometric dosing ensured similar MF exposure in children (<12 years) and adults. CONCLUSIONS PM/MF and SSG/PM efficacies were similar, and adverse drug reactions were as expected given the drugs safety profiles. With 1 less injection each day, reduced treatment duration, and no risk of SSG-associated life-threatening cardiotoxicity, PM/MF is a more patient-friendly alternative for children and adults with primary visceral leishmaniasis in eastern Africa.

Abstract
BACKGROUND Visceral leishmaniasis (VL) is one of the most neglected tropical infectious diseases. It is fatal if left untreated. The objective of this study was to assess the efficacy and safety of 17-day injections of combined regimen of sodium stibogluconate and paromomycin (SSG/PM) in HIV-negative VL patients. METHODS A retrospective analysis of medical records of VL patients treated in the University of Gondar Hospital during period 2012-2019 was carried out. RESULTS A total of 2836 patients were treated for VL from 2012 to 2019. Of these 1233 were treated with SSG-PM, and 1000 of them were included in the study. Initial cure was achieved in 922 (92.2%) patients. The frequency of treatment failure, treatment interruptions, default and deaths respectively were 30 (3%), 20 (2%), 13 (1.3%) and 15 (1.5%). Among 280 patients who completed 6-month follow up, the final cure was 93.9% (263/280), 4 (1.4%) relapsed and 13 (4.6%) developed post-kala-azar dermal leishmaniasis (PKDL). The most common adverse events (AEs) were raised liver transaminases (35.1%; 351 patients), injection site pain (29.1%, 291 patients) and raised serum alpha-amylase (29.1%, 291 patients). Factors associated with poor treatment outcomes were sepsis, pneumonia, and adverse events. CONCLUSION A combination of SSG at 20mg/kg with upper daily maximum dose of 850mg and PM was effective for achieving initial cure at end of treatment and safe for treatment of HIV negative VL patients in northwestern Ethiopia. Our data are consistent with previous reports and confirms effectiveness of SSG/PM treatment regimen in the Eastern African countries. Efficacy at 6-months (93.9%) was estimated on data derived from patients who completed follow up and needs to be interrogated by future studies.

Abstract
Canine leishmaniosis due to Leishmania infantum is a widespread zoonotic disease. Although aminosidine can be an effective treatment, current therapeutic recommendations do not advocate its use, mainly due to concerns regarding the potential nephrotoxicity and ototoxicity of this drug. The aim of this randomized, blinded, controlled study was to evaluate the nephrotoxicity and ototoxicity of aminosidine-allopurinol combination and compare it with that of meglumine antimonate-allopurinol combination in non-azotemic dogs with leishmaniosis. Forty dogs with leishmaniosis were randomly assigned to be treated with either aminosidine at 15 mg/kg, subcutaneously, once daily for 28 days (group A) or with meglumine antimonate at 100 mg/kg, subcutaneously, once daily for 28 days (group B). In addition to either drug, dogs in both groups were administered allopurinol at 10 mg/kg per os twice daily for 2 months. Kidney function was evaluated through measurement of serum creatinine, urea nitrogen, inorganic phosphorus, and cystatin-c concentrations and complete urinalysis, including protein-to-creatinine ratio, at baseline and after 14, 28, and 60 days from the beginning of the treatment. At the same time points, vestibular and auditory functions were evaluated through neurological examination and brainstem auditory evoked response (BAER) recordings of wave I, wave V, inter-wave I-V latencies, and minimum hearing thresholds. None of the dogs developed clinicopathological evidence of kidney disease during the study. Serum creatinine concentration increased >0.3 mg/dl over baseline in 2 dogs in group A and in 5 dogs in group B. Parameters of kidney function were not significantly different or were improved compared to baseline and the only difference between the two groups was the lower concentration of serum creatinine in group A. None of the dogs developed peripheral vestibular syndrome or hearing impairment. At the end of the study, parameters of auditory function were not significantly different or were improved compared to baseline and there were no differences between the two groups. The results of this study show that the nephrotoxicity and ototoxicity of aminosidine, when administered to non-azotemic dogs with leishmaniosis at 15 mg/kg subcutaneously once daily for 28 days along with allopurinol, is minimal and does not differ from that of meglumine antimonate.

Abstract
BACKGROUND In 2010, WHO recommended the use of new short-course treatment regimens in kala-azar elimination efforts for the Indian subcontinent. Although phase 3 studies have shown excellent results, there remains a lack of evidence on a wider treatment population and the safety and effectiveness of these regimens under field conditions. METHODS This was an open label, prospective, non-randomized, non-comparative, multi-centric trial conducted within public health facilities in two highly endemic districts and a specialist referral centre in Bihar, India. Three treatment regimens were tested: single dose AmBisome (SDA), concomitant miltefosine and paromomycin (Milt+PM), and concomitant AmBisome and miltefosine (AmB+Milt). Patients with complicated disease or significant co-morbidities were treated in the SDA arm. Sample sizes were set at a minimum of 300 per arm, taking into account inter-site variation and an estimated failure risk of 5% with 5% precision. Outcomes of drug effectiveness and safety were measured at 6 months. The trial was prospectively registered with the Clinical Trials Registry India: CTRI/2012/08/002891. RESULTS Out of 1,761 patients recruited, 50.6% (n = 891) received SDA, 20.3% (n = 358) AmB+Milt and 29.1% (n = 512) Milt+PM. In the ITT analysis, the final cure rates were SDA 91.4% (95% CI 89.3-93.1), AmB+Milt 88.8% (95% CI 85.1-91.9) and Milt+PM 96.9% (95% CI 95.0-98.2). In the complete case analysis, cure rates were SDA 95.5% (95% CI 93.9-96.8), AmB+Milt 95.5% (95% CI 92.7-97.5) and Milt+PM 99.6% (95% CI 98.6-99.9). All three regimens were safe, with 5 severe adverse events in the SDA arm, two of which were considered to be drug related. CONCLUSION All regimens showed acceptable outcomes and safety profiles in a range of patients under field conditions. Phase IV field-based studies, although extremely rare for neglected tropical diseases, are good practice and an important step in validating the results of more restrictive hospital-based studies before widespread implementation, and in this case contributed to national level policy change in India. TRIAL REGISTRATION Clinical trial is registered at Clinical trial registry of India (CTRI/2012/08/002891, Registered on 16/08/2012, Trial Registered Prospectively).

Abstract
BACKGROUND Cutaneous leishmaniasis, caused by a parasitic infection, is considered one of the most serious skin diseases in many low- and middle-income countries. Old World cutaneous leishmaniasis (OWCL) is caused by species found in Africa, Asia, the Middle East, the Mediterranean, and India. The most commonly prescribed treatments are antimonials, but other drugs have been used with varying success. As OWCL tends to heal spontaneously, it is necessary to justify the use of systemic and topical treatments. This is an update of a Cochrane Review first published in 2008. OBJECTIVES To assess the effects of therapeutic interventions for the localised form of Old World cutaneous leishmaniasis. SEARCH METHODS We updated our searches of the following databases to November 2016: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trials registers and checked the reference lists of included studies for further references to relevant randomised controlled trials (RCTs). We wrote to national programme managers, general co-ordinators, directors, clinicians, WHO-EMRO regional officers of endemic countries, pharmaceutical companies, tropical medicine centres, and authors of relevant papers for further information about relevant unpublished and ongoing trials. We undertook a separate search for adverse effects of interventions for Old World cutaneous leishmaniasis in September 2015 using MEDLINE. SELECTION CRITERIA Randomised controlled trials of either single or combination treatments in immunocompetent people with OWCL confirmed by smear, histology, culture, or polymerase chain reaction. The comparators were either no treatment, placebo/vehicle, and/or another active compound. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias and extracted data. We only synthesised data when we were able to identify at least two studies investigating similar treatments and reporting data amenable to pooling. We also recorded data about adverse effects from the corresponding search. MAIN RESULTS We included 89 studies (of which 40 were new to this update) in 10,583 people with OWCL. The studies included were conducted mainly in the Far or Middle East at regional hospitals, local healthcare clinics, and skin disease research centres. Women accounted for 41.5% of the participants (range: 23% to 80%). The overall mean age of participants was 25 years (range 12 to 56). Most studies lasted between two to six months, with the longest lasting two years; average duration was four months. Most studies were at unclear or high risk for most bias domains. A lack of blinding and reporting bias were present in almost 40% of studies. Two trials were at low risk of bias for all domains. Trials reported the causative species poorly.Here we provide results for the two main comparisons identified: itraconazole (200 mg for six to eight weeks) versus placebo; and paromomycin ointment (15% plus 10% urea, twice daily for 14 days) versus vehicle.In the comparison of oral itraconazole versus placebo, at 2.5 months' follow up, 85/125 participants in the itraconazole group achieved complete cure compared to 54/119 in the placebo group (RR 3.70, 95% CI 0.35 to 38.99; 3 studies; 244 participants). In one study, microbiological or histopathological cure of skin lesions only occurred in the itraconazole group after a mean follow-up of 2.5 months (RR 17.00, 95% CI 0.47 to 612.21; 20 participants). However, although the analyses favour oral itraconazole for these outcomes, we cannot be confident in the results due to the very low certainty evidence. More side effects of mild abdominal pain and nausea (RR 2.36, 95% CI 0.74 to 7.47; 3 studies; 204 participants) and mild abnormal liver function (RR 3.08, 95% CI 0.53 to 17.98; 3 studies; 84 participants) occurred in the itraconazole group (as well as reports of headaches and dizziness), compared with the placebo group, but again we rated the certainty of evidence as very low so are unsure of the results.When comparing paromomycin with vehicle, there was no difference in the number of participants who achieved complete cure (RR of 1.00, 95% CI 0.86, 1.17; 383 participants, 2 studies) and microbiological or histopathological cure of skin lesions after a mean follow-up of 2.5 months (RR 1.03, CI 0.88 to 1.20; 383 participants, 2 studies), but the paromomycin group had more skin/local reactions (such as inflammation, vesiculation, pain, redness, or itch) (RR 1.42, 95% CI 0.67 to 3.01; 4 studies; 713 participants). For all of these outcomes, the certainty of evidence was very low, meaning we are unsure about these results.Trial authors did not report the percentage of lesions cured after the end of treatment or speed of healing for either of these key comparisons. AUTHORS' CONCLUSIONS There was very low-certainty evidence to support the effectiveness of itraconazole and paromomycin ointment for OWCL in terms of cure (i.e. microbiological or histopathological cure and percentage of participants completely cured). Both of these interventions incited more adverse effects, which were mild in nature, than their comparisons, but we could draw no conclusions regarding safety due to the very low certainty of the evidence for this outcome.We downgraded the key outcomes in these two comparisons due to high risk of bias, inconsistency between the results, and imprecision. There is a need for large, well-designed international studies that evaluate long-term effects of current therapies and enable a reliable conclusion about treatments. Future trials should specify the species of leishmaniasis; trials on types caused by Leishmania infantum, L aethiopica, andL donovani are lacking. Research into the effects of treating women of childbearing age, children, people with comorbid conditions, and those who are immunocompromised would also be helpful.It was difficult to evaluate the overall efficacy of any of the numerous treatments due to the variable treatment regimens examined and because RCTs evaluated different Leishmania species and took place in different geographical areas. Some outcomes we looked for but did not find were degree of functional and aesthetic impairment, change in ability to detect Leishmania, quality of life, and emergence of resistance. There were only limited data on prevention of scarring.

Abstract
Background AmBisome therapy for VL has an excellent efficacy and safety profile and has been adopted as a first-line regimen in Bangladesh. Second-line treatment options are limited and should preferably be given in short course combinations in order to prevent the development of resistant strains. Combination regimens including AmBisome, paromomycin and miltefosine have proved to be safe and effective in the treatment of VL in India. In the present study, the safety and efficacy of these same combinations were assessed in field conditions in Bangladesh. Methods The safety and efficacy of three combination regimens: a 5 mg/kg single dose of AmBisome + 7 subsequent days of miltefosine (2.5 mg/kg/day), a 5 mg/kg single dose of AmBisome + 10 subsequent days of paromomycin (15 mg/kg/day) and 10 days of paromomycin (15 mg/kg/day) + miltefosine (2.5 mg/kg/day), were compared with a standard regimen of AmBisome 15 mg/kg given in 5 mg/kg doses on days 1, 3 and 5. This was a phase III open label, individually randomized clinical trial. Patients from 5 to 60 years with uncomplicated primary VL were recruited from the Community Based Medical College Bangladesh (CBMC,B) and the Upazila Health Complexes of Trishal, Bhaluka and Fulbaria (all located in Mymensingh district), and randomly assigned to one of the treatments. The objective was to assess safety and definitive cure at 6 months after treatment. Results 601 patients recruited between July 2010 and September 2013 received either AmBisome monotherapy (n = 158), AmBisome + paromomycin (n = 159), AmBisome + miltefosine (n = 142) or paromomycin + miltefosine (n = 142). At 6 months post- treatment, final cure rates for the intention-to-treat population were 98.1% (95%CI 96.0–100) for AmBisome monotherapy, 99.4% (95%CI 98.2–100) for the AmBisome + paromomycin arm, 94.4% (95%CI 90.6–98.2) for the AmBisome + miltefosine arm, and 97.9% (95%CI 95.5–100) for paromomycin + miltefosine arm. There were 12 serious adverse events in the study in 11 patients that included 3 non-study drug related deaths. There were no relapses or PKDL up to 6 months follow-up. All treatments were well tolerated with no unexpected side effects. Adverse events were most frequent during treatment with miltefosine + paromomycin, three serious adverse events related to the treatment occurred in this arm, all of which resolved. Conclusion None of the combinations were inferior to AmBisome in both the intention-to-treat and per-protocol populations. All the combinations demonstrated excellent overall efficacy, were well tolerated and safe, and could be deployed under field conditions in Bangladesh. The trial was conducted by the International Centre for Diarrhoeal Disease Research (ICDDR,B) and the Shaheed Suhrawardy Medical College (ShSMC), Dhaka, in collaboration with the trial sites and sponsored by the Drugs for Neglected Diseases initiative (DNDi). Trial registration ClinicalTrials.gov NCT01122771 Treatment is one of the key strategies for visceral leishmaniasis control and elimination. Historically a number of monotherapy drugs for VL treatment were used in Bangladesh, including pentavalent antimonials, amphotericin B deoxycholate (AmB), and miltefosine (MF). With the limited number of drugs available, it was necessary to preserve existing drugs and also to develop shorter and safer treatment regimens. At the time the study was initiated, miltefosine monotherapy was a recommended first-line treatment in Bangladesh. The present study aimed to provide safety and efficacy data for three short-course combination regimens including AmBisome, miltefosine and paromomycin when rolled out in field conditions in Bangladesh, and to compare these to AmBisome monotherapy. All combinations proved non-inferior to AmBisome monotherapy and were safe and well tolerated. This study was implemented in field conditions at Upazila level with treatment provided by government doctors, providing further evidence for scaling up new regimens in national program contexts within the public health sector.

Abstract
Although pentavalent antimonials are often used in the first-line treatment of cutaneous leishmaniasis (CL), they have several adverse effects. Intralesional administration of antimonials and other antileishmanial drugs can be painful. In the present, double-blind, randomized study, to determine if topical treatment with paromomycin is effective in the treatment of CL, 35 cases of CL were treated, twice daily for 30 days, with a commercial skin-care lotion containing 10% urea (the placebo) and another 30 were similarly treated with the same lotion to which paromomycin sulphate had been added (to give a concentration of 15%). Each case was assessed clinically 7, 14, 21 and 30 days after treatment began, and parasitologically 30 and 60 days after the initiation of treatment. Five (17%) and five (17%) of the cases treated with paromomycin showed complete healing, with the apparent clearance of amastigotes from their lesions, 30 and 60 days after treatment began, respectively. At the same time-points, however, the lesions on six (17%) and seven (20%) of the cases in the placebo group, respectively, also appeared to have healed completely. Ointment containing 15% paromomycin therefore appears ineffective in the treatment of CL, at least when applied twice daily for 30 days to the lesions of cases from an endemic area of Isfahan, Iran.

Abstract
BACKGROUND There is a need for a simple and efficacious treatment for cutaneous leishmaniasis with an acceptable side-effect profile. METHODS We conducted a randomized, vehicle-controlled phase 3 trial of topical treatments containing 15% paromomycin, with and without 0.5% gentamicin, for cutaneous leishmaniasis caused by Leishmania major in Tunisia. We randomly assigned 375 patients with one to five ulcerative lesions from cutaneous leishmaniasis to receive a cream containing 15% paromomycin-0.5% gentamicin (called WR 279,396), 15% paromomycin alone, or vehicle control (with the same base as the other two creams but containing neither paromomycin nor gentamicin). Each lesion was treated once daily for 20 days. The primary end point was the cure of the index lesion. Cure was defined as at least 50% reduction in the size of the index lesion by 42 days, complete reepithelialization by 98 days, and absence of relapse by the end of the trial (168 days). Any withdrawal from the trial was considered a treatment failure. RESULTS The rate of cure of the index lesion was 81% (95% confidence interval [CI], 73 to 87) for paromomycin-gentamicin, 82% (95% CI, 74 to 87) for paromomycin alone, and 58% (95% CI, 50 to 67) for vehicle control (P<0.001 for each treatment group vs. the vehicle-control group). Cure of the index lesion was accompanied by cure of all other lesions except in five patients, one in each of the paromomycin groups and three in the vehicle-control group. Mild-to-moderate application-site reactions were more frequent in the paromomycin groups than in the vehicle-control group. CONCLUSIONS This trial provides evidence of the efficacy of paromomycin-gentamicin and paromomycin alone for ulcerative L. major disease.

Abstract
Background Alternative treatments for visceral leishmaniasis (VL) are required in East Africa. Paromomycin sulphate (PM) has been shown to be efficacious for VL treatment in India. Methods A multi-centre randomized-controlled trial (RCT) to compare efficacy and safety of PM (20 mg/kg/day for 21 days) and PM plus sodium stibogluconate (SSG) combination (PM, 15 mg/kg/day and SSG, 20 mg/kg/day for 17 days) with SSG (20 mg/kg/day for 30 days) for treatment of VL in East Africa. Patients aged 4–60 years with parasitologically confirmed VL were enrolled, excluding patients with contraindications. Primary and secondary efficacy outcomes were parasite clearance at 6-months follow-up and end of treatment, respectively. Safety was assessed mainly using adverse event (AE) data. Findings The PM versus SSG comparison enrolled 205 patients per arm with primary efficacy data available for 198 and 200 patients respectively. The SSG & PM versus SSG comparison enrolled 381 and 386 patients per arm respectively, with primary efficacy data available for 359 patients per arm. In Intention-to-Treat complete-case analyses, the efficacy of PM was significantly lower than SSG (84.3% versus 94.1%, difference = 9.7%, 95% confidence interval, CI: 3.6 to 15.7%, p = 0.002). The efficacy of SSG & PM was comparable to SSG (91.4% versus 93.9%, difference = 2.5%, 95% CI: −1.3 to 6.3%, p = 0.198). End of treatment efficacy results were very similar. There were no apparent differences in the safety profile of the three treatment regimens. Conclusion The 17 day SSG & PM combination treatment had a good safety profile and was similar in efficacy to the standard 30 day SSG treatment, suggesting suitability for VL treatment in East Africa. Clinical Trials Registration www.clinicaltrials.govNCT00255567 Visceral leishmaniasis (VL) is a parasitic disease with about 500,000 new cases each year and is fatal if untreated. The current standard therapy involves long courses, has toxicity and there is evidence of increasing resistance. New and better treatment options are urgently needed. Recently, the antibiotic paromomycin (PM) was tested and registered in India to treat this disease, but the same dose of PM monotherapy evaluated and registered in India was not efficacious in Sudan. This article reports the results of a clinical trial to test the effectiveness of injectable PM either alone (in a higher dose) or in combination with sodium stibogluconate (SSG) against the standard SSG monotherapy treatment in four East African countries—Sudan, Kenya, Ethiopia and Uganda. The study showed that the combination of SSG &PM was as efficacious and safe as the standard SSG treatment, with the advantages of being cheaper and requiring only 17 days rather than 30 days of treatment. In March 2010, a WHO Expert Committee recommended the use of the SSG & PM combination as a first line treatment for VL in East Africa.

Abstract
BACKGROUND Improved treatment approaches are needed for visceral leishmaniasis. We assessed the efficacy and safety of three potential short-course combination treatments compared with the standard monotherapy in India. METHODS Standard treatment (1 mg/kg amphotericin B infusion on alternate days for 30 days, total dose 15 mg/kg) was compared with three drug combinations (single injection of 5 mg/kg liposomal amphotericin B and 7-day 50 mg oral miltefosine or single 10-day 11 mg/kg intramuscular paromomycin; or 10 days each of miltefosine and paromomycin) in an open-label, parallel-group, non-inferiority, randomised controlled trial in two hospital sites in Bihar, India. Patients aged 5-60 years with parasitologically confirmed visceral leishmaniasis were randomly assigned one of the four treatments by the trial statistician by use of a computer-generated list. Clinical assessments were done at the end of treatment (15 days on combination treatment; 31 days for standard treatment) and after 45 days and 6 months. The primary endpoint was definitive cure (defined as no sign or symptom of visceral leishmaniasis and parasitologically cured to the last follow-up). Analyses were done both by intention to treat and per protocol. This trial is registered with ClinicalTrials.gov, number NCT00696969. FINDINGS Between June, 2008, and July, 2009, 634 patients were assigned amphotericin B (n=157), liposomal amphotericin B with miltefosine (n=160) or paromomycin (n=158), or miltefosine and paromomycin (n=159). 618 patients were in the per-protocol population. There were two relapses in each group. The numbers with definitive cure at 6 months for the intention-to-treat population were 146 (cure rate 93·0%; CI 87·5-96·3) for amphotericin B, 156 (97·5%; 93·3-99·2) for liposomal amphotericin B and miltefosine, 154 (97·5%; 93·24-99·2) for liposomal amphotericin B and paromomycin, and 157 (98·7%; 95·1-99·8) for miltefosine and paromomycin. All combinations were non-inferior to the standard treatment, in both the intention-to-treat and per-protocol populations. Patients in the combination groups had fewer adverse events than did those assigned standard treatment. INTERPRETATION Combination treatments for visceral leishmaniasis are efficacious and safe, and decrease the duration of therapy, thereby encouraging adherence and reducing emergence of drug-resistant parasites.

Abstract
Background A recent study has shown that treatment of visceral leishmaniasis (VL) with the standard dose of 15 mg/kg/day of paromomycin sulphate (PM) for 21 days was not efficacious in patients in Sudan. We therefore decided to test the efficacy of paramomycin for a longer treatment duration (15 mg/kg/day for 28 days) and at the higher dose of 20 mg/kg/day for 21 days. Methods This randomized, open-label, dose-finding, phase II study assessed the two above high-dose PM treatment regimens. Patients with clinical features and positive bone-marrow aspirates for VL were enrolled. All patients received their assigned courses of PM intramuscularly and adverse events were monitored. Parasite clearance in bone-marrow aspirates was tested by microscopy at end of treatment (EOT, primary efficacy endpoint), 3 months (in patients who were not clinically well) and 6 months after EOT (secondary efficacy endpoint). Pharmacokinetic data were obtained from a subset of patients weighing over 30 kg. Findings 42 patients (21 per group) aged between 4 and 60 years were enrolled. At EOT, 85% of patients (95% confidence interval [CI]: 63.7% to 97.0%) in the 20 mg/kg/day group and 90% of patients (95% CI: 69.6% to 98.8%) in the 15 mg/kg/day group had parasite clearance. Six months after treatment, efficacy was 80.0% (95% CI: 56.3% to 94.3%) and 81.0% (95% CI: 58.1% to 94.6%) in the 20 mg/kg/day and 15 mg/kg/day groups, respectively. There were no serious adverse events. Pharmacokinetic profiles suggested a difference between the two doses, although numbers of patients recruited were too few to make it significant (n = 3 and n = 6 in the 20 mg/kg/day and 15 mg/kg/day groups, respectively). Conclusion Data suggest that both high dose regimens were more efficacious than the standard 15 mg/kg/day PM for 21 days and could be further evaluated in phase III studies in East Africa. Trial Registration ClinicalTrials.gov NCT00255567 Visceral leishmaniasis (VL) is a parasitic disease transmitted through the bite of sandflies. The WHO estimates 500,000 new cases of VL each year, with more than 90% of cases occurring in Southeast Asia, East Africa, and South America. If left untreated, VL can be fatal. We had previously conducted a large multi-center study in Sudan, East Africa, to assess the efficacy of paromomycin (PM) alone or in combination with sodium stibogluconate. Clinical studies in India have shown that 15 mg/kg/day PM for 21 days was an effective cure. However, the same treatment regimen was not efficacious in two study sites in Sudan. Here, our aim was to assess two high-dose regimens of PM in Sudan: 15 mg/kg/day for 28 days and 20 mg/kg/day for 21 days. The results suggest that, at these total doses, PM is more efficacious than when given daily at 15 mg/kg for 21 days, and that high doses are required to treat VL in Sudan. Efficacy of 20 mg/kg/day PM for 21 days is currently being evaluated in a prospective, comparative phase III trial in East Africa.

Abstract
Background Visceral leishmaniasis (VL) is a major health problem in developing countries. The untreated disease is fatal, available treatment is expensive and often toxic, and drug resistance is increasing. Improved treatment options are needed. Paromomycin was shown to be an efficacious first-line treatment with low toxicity in India. Methods This was a 3-arm multicentre, open-label, randomized, controlled clinical trial to compare three treatment regimens for VL in East Africa: paromomycin sulphate (PM) at 15 mg/kg/day for 21 days versus sodium stibogluconate (SSG) at 20 mg/kg/day for 30 days; and the combination of both dose regimens for 17 days. The primary efficacy endpoint was cure based on parasite-free tissue aspirates taken 6 months after treatment. Findings Overall, 135 patients per arm were enrolled at five centres in Sudan (2 sites), Kenya (1) and Ethiopia (2), when the PM arm had to be discontinued due to poor efficacy. The trial has continued with the higher dose of PM as well as the combination of PM and SSG arms. These results will be reported later. Baseline patient characteristics were similar among treatment arms. The overall cure with PM was significantly inferior to that with SSG (63.8% versus 92.2%; difference 28.5%, 95%CI 18.8% to 38.8%, p<0.001). The efficacy of PM varied among centres and was significantly lower in Sudan (14.3% and 46.7%) than in Kenya (80.0%) and Ethiopia (75.0% and 96.6%). No major safety issues with PM were identified. Conclusion The efficacy of PM at 15 mg/kg/day for 21 days was inadequate, particularly in Sudan. The efficacy of higher doses and the combination treatment warrant further studies. Visceral leishmaniasis (VL) is a fatal parasitic disease with 500,000 new cases each year according to WHO estimates. New and better treatment options are urgently needed in disease endemic areas due to the long courses, toxicity and development of resistance to current treatments. Recently, the antibiotic paromomycin was tested and registered in India to treat this disease. The current study describes a clinical trial to test the effectiveness of injectable paromomycin, either alone or in combination with the standard drug sodium stibogluconate in three East African countries—Sudan, Kenya and Ethiopia. The study showed that at the same paromomycin dose that was successfully used and registered in India, a far poorer outcome was obtained, particularly in Sudan, suggesting that there are either differences in the patients ability to respond to the drug or in the susceptibility of parasites in East Africa compared with those in India. However, no major safety concerns were noted with the treatment. Further research was initiated to see if a higher dose of paromomycin would perform better, especially in Sudan. The results of this and the performance of the combination arm will be reported later. Our study highlights the importance of considering geographical differences to treatment responses.

Abstract
Paromomycin, an aminoglycoside, is known to cause several side effects like nephrotoxicity and ototoxicity like other aminoglycosides but tetany has not been reported. Three cases of tetany were detected in the patients of kala-azar treated with paromomycin. They were promptly treated with intravenous 10 per cent calcium gluconate and tetany was relieved immediately and treatment with paromomycin continued with oral calcium supplement. After completion of 21 days treatment with paromomycin patients' splenic aspirates were free of parasites. Paromomycin may cause temporary tubular damage leading to calcium wasting in urine and hypocalcaemia resulting in tetany. Prompt detection of symptoms and intravenous calcium gluconate treatment promptly reverse the situation.

Abstract
BACKGROUND Visceral leishmaniasis (kala-azar) affects large, rural, resource-poor populations in South Asia, Africa, and Brazil. Safe, effective, and affordable new therapies are needed. We conducted a randomized, controlled, phase 3 open-label study comparing paromomycin, an aminoglycoside, with amphotericin B, the present standard of care in Bihar, India. METHODS In four treatment centers for visceral leishmaniasis, 667 patients between 5 and 55 years of age who were negative for the human immunodeficiency virus and had parasitologically confirmed visceral leishmaniasis were randomly assigned in a 3:1 ratio to receive paromomycin (502 patients) at a dose of 11 mg per kilogram of body weight intramuscularly daily for 21 days or amphotericin B (165 patients) at a dose of 1 mg per kilogram intravenously every other day for 30 days. Final cure was assessed 6 months after the end of treatment; safety assessments included daily clinical evaluations and weekly laboratory and audiometric evaluations. Noninferiority testing was used to compare 6-month cure rates, with a chosen margin of noninferiority of 10 percentage points. RESULTS Paromomycin was shown to be noninferior to amphotericin B (final cure rate, 94.6% vs. 98.8%; difference, 4.2 percentage points; upper bound of the 97.5% confidence interval, 6.9; P<0.001). Mortality rates in the two groups were less than 1%. Adverse events, which were more common among patients receiving paromomycin than among those receiving amphotericin B (6% vs. 2%, P=0.02), included transient elevation of aspartate aminotransferase levels (>3 times the upper limit of the normal range); transient reversible ototoxicity (2% vs. 0, P=0.20); and injection-site pain (55% vs. 0, P<0.001); and in patients receiving amphotericin B, as compared with those receiving paromomycin, nephrotoxicity (4% vs. 0, P<0.001), fevers (57% vs. 3%), rigors (24% vs. 0, P<0.001), and vomiting (10% vs. <1%, P<0.001). CONCLUSIONS Paromomycin was shown to be noninferior to amphotericin B for the treatment of visceral leishmaniasis in India. (ClinicalTrials.gov number, NCT00216346.)

Abstract
Few therapeutic options are available for mucocutaneous leishmaniasis (MCL). We conducted a randomized open trial to evaluate the efficacy, safety, and tolerance of parenteral aminosidine sulphate (AS) 14 mg/kg/d for 21 days compared with intravenous meglumine antimonate (MA) 20 mg/kg/d for 28 days in patients with moderate MCL in Cuzco, Peru. Cure was defined as complete healing with re-epithelialization within 1 year of follow-up. The trial was stopped after 38 patients were enrolled (17 in the MA group and 21 in the AS group) because of marked differences in response. Study groups were comparable in baseline characteristics. Cure rates were 0/21 in the AS group compared with 8/17 (47%, 95% confidence interval: 23-71%) in the MA group (P < 0.001). Side effects and laboratory abnormalities were mild in both groups. We conclude that parenteral AS given on its own is not effective for MCL in Peru.

Abstract
A controlled and blinded study was conducted to evaluate the efficacy and safety of a treatment with paromomycin sulphate against an experimental Giardia infection in calves. Animals were infected with 10(5)Giardia cysts of cattle origin and were either treated 11 days later with 25, 50 or 75 mg paromomycin/(kg body weight per day) during 5 consecutive days or not treated (control group). Efficacy was evaluated based on reduction in cyst excretion. Furthermore weight gain and diarrhea scores were monitored. In the group treated with 75 mg/kg per day there was a 100% reduction in cyst excretion until 9 days after the start of the treatment (D9) and a very high reduction (> or =98%) until D13. There was a high reduction (> or =93%) until D9 and D13 in the groups treated with 25 and 50 mg/kg, respectively. The cumulative cyst excretion on D13 was significantly (P<0.05) lower in the groups treated with 75 and 50 mg/kg compared to the control group. Although there was a trend towards higher weight gain and less diarrhea in the treated groups, differences between groups were not significant. No adverse reactions to the paromomycin treatment were recorded. Furthermore, the need for reliable parameters for evaluation of treatments against protozoal infections is emphasised.

Abstract
A double-blind, randomized trial was undertaken in Guatemala to determine the therapeutic efficacy of an ointment for the treatment of cutaneous leishmaniasis that contained 15% paromomycin and 12% methylbenzethonium chloride and that was applied twice a day for 20 days. The treatment group included 35 patients, and the placebo group included 33 patients. The initial clinical response rate (13 weeks after completing the treatment) was 91.4% in the treatment group and 39.4% in the placebo group. The final clinical response rate at the 12-month follow-up examination was 85.7% (31 of 35) in the treatment group and 39.4% (13 of 33) in the placebo group (P < or = 0.001). In general, the treatment was well tolerated and was never interrupted because of adverse effects. The number of adverse effects reported in the placebo group was lower than in the treatment group (16 events versus 30 events). All adverse effects reported by patients disappeared within 1 week of completing the treatment. Our findings show that the combination of paromomycin with methylbenzethonium chloride for 20 days is a good alternative for antimonial treatments of cutaneous leishmaniasis in Guatemala.

Abstract
Acute renal failure was diagnosed in 4 cats receiving paromomycin orally for treatment of infectious enteritis. All 4 cats responded to fluid therapy and recovered normal or near-normal renal function; however, 3 of the cats subsequently became deaf and developed cataracts. Toxicoses were attributed to a combination of an excessive dosage of paromomycin and absorption of the drug across injured intestinal mucosal epithelium. Pharmacokinetic studies are needed to further define the disposition of paromomycin after oral administration to cats.

Abstract
OBJECTIVES To assess the efficacy and tolerability of aminosidine compared with sodium stibogluconate for treating visceral leishmaniasis. DESIGN Randomised, unblinded, controlled trial with 180 day follow up. SETTING Kala-Azar Research Centre, Brahmpura, Muzaffarpur, Bihar, India. SUBJECTS People of either sex aged 6-50 years with symptoms and signs suggestive of visceral leishmaniasis (fever, loss of appetite, enlarged spleen) with leishmania amastigotes detected in Giemsa stained aspirates of spleen or bone marrow. INTERVENTIONS Aminosidine at three daily doses (12, 16, and 20 mg/kg) for 21 days and sodium stibogluconate 20 mg/kg/day for 30 days. MAIN OUTCOME MEASURES Laboratory measures of efficacy: parasite count, haemoglobin concentration, white cell count, platelet count, serum albumin concentration. Clinical measures of efficacy: spleen size, fever, body weight, and liver size. Measures of safety: liver and renal function tests, reports of adverse events. RESULTS Of the 120 patients enrolled (30 per treatment arm), 119 completed treatment and follow up. Cure at end of follow up was achieved in 23 (77%), 28 (93%), and 29 (97%) patients treated with 12, 16, and 20 mg aminosidine/kg/day respectively, and in 19 (63%) patients given sodium stibogluconate. At 16 and 20 mg/kg/day, aminosidine was significantly more active than sodium stibogluconate in both clinical and laboratory measures of efficacy. No significant clinical or laboratory toxicity occurred in any treatment group. CONCLUSIONS A 21 day course of aminosidine 16 or 20 mg/kg/day should be considered as first line treatment for visceral leishmaniasis in Bihar.

Abstract
Vaginal trichomoniasis poses a difficult therapeutic challenge when metronidazole is ineffective or contraindicated. We conducted a retrospective study of 6.25% paromomycin cream in the treatment of nine women referred with cases of vaginal trichomoniasis where metronidazole resistance or allergy was present. Results obtained immediately and 1 month after treatment were reviewed. The median age of the patients was 46 years; four women were nulliparous. The median symptom duration was 1 year. Five women were allergic to metronidazole. In four cases, resistance to high doses of metronidazole was demonstrated. Smears or cultures were positive immediately after treatment for three patients; a fourth relapsed 2 weeks later. Of these patients for whom treatment failed, one was cured with a 3-week course of paromomycin cream, and another was successfully treated with paromomycin cream and oral tinidazole. Three patients developed vaginal ulcerations that resolved spontaneously. Adverse effects may be a result of local formulation. Paromomycin cream was useful for treatment of cases of trichomonas infection where metronidazole resistance or allergy was encountered.

Abstract
Forty-nine children in need of antibacterial treatment for a severe episode of bacterial diarrhoea were consecutively treated with either an oral paediatric suspension of rifaximin (100 mg every six hours for an average of four days: 24 patients), or paromomycin (125 mg every six hours for an average of four days: 25 patients). Stools (number and form), enteritis symptoms and signs, and intolerance manifestations were all monitored on each day of treatment. A stool culture was performed on the first available stool after enrolment and after the end of treatment to monitor the drugs' antibacterial activity. A similar rate of bacteriological cure, with normalisation of stools and elimination of the clinical symptomatology, was attained by the two antibiotics, with statistical significance of changes vs. baseline being apparent on the second treatment day, in both treatment groups. Rifaximin results were quicker (treatment lasted three days in several cases) and on the whole slightly better (though without statistical significance) than those of paromomycin: 21/24 vs. 20/25 children were completely cured, with a failure rate of three and five cases, respectively. Systemic and local tolerance of both treatments were very good in all children.

Abstract
The authors treated with paromomycin 25 patients, with AIDS and cryptosporidiosis. The drug was given orally in a doses of 500 mg qid, for a period of 14 days. Tolerance was good, with just two cases of mild side-effects. Clinical improvement was obtained in 19 (76%) patients. Parasitological cure, however, occurred only in a low percentage (25%). In some cases where initial success was observed, recrudescence occurred after some weeks or few months, but with retreatment again clinical improvement was obtained. Even if it does not lead to frequent parasite eradication, the good clinical results and tolerance permit us to consider paromomycin one of the few drugs effective for the treatment of cryptosporidial diarrhea in AIDS patients. Studies with maintainance therapy are indicated.

Abstract
The effect of a two-week regimen of topical aminosidine was investigated in a randomized, double-blind, placebo-controlled trial of 251 selected Iranian patients with zoonotic cutaneous leishmaniasis. Patients underwent clinical and parasitologic assessment before and 15 (end of therapy), 45, and 105 days after starting the treatment. Aminosidine ointment was safe and well-tolerated, and produced significant reductions in the prevalence of parasitologically positive smears on days 15 and 105 (but not day 45) after treatment compared with placebo. However, there was no clear clinical benefit at any stage after treatment. We conclude that this twice a day two-week regimen of aminosidine was inadequate to accelerate the recovery of most cases of cutaneous leishmaniasis. However, the ointment did show some clear evidence of parasitologic efficacy and should now be studied in longer or more frequent regimens in an effort to prevent parasitologic relapse and thus promote clinical improvement.

In the dexamethasone-treated rat model of cryptosporidiosis, paromomycin was effective at a dosage of 50 mg/kg/day or more for ileal infection and 200 mg/kg/day or more for cecal infection. At 1 and 3 weeks after treatment, a persistent infection was demonstrated in all rats. These results confirm the anticryptosporidial activity of paromomycin and underscore the limitations of this compound because of its potential toxicity at such high dosages and its inability to eradicate the infection.

Abstract
A randomized, placebo-controlled, double-blind trial was carried out in 1992 in central Tunisia to assess the tolerability and efficacy of paromomycin ointment against zoonotic cutaneous leishmaniasis caused by Leishmania major. One hundred fifteen patients, 2--60 years of age, with a single lesion of parasitologically confirmed cutaneous leishmaniasis, were included in the trial. The ointment was applied twice a day from day 1 through day 14. Clinical and parasitologic evaluations of lesions were done at days 0, 15, 45, and 105. Fifty-seven patients were allocated the treatment and 58 the placebo. Based on local toxicity and laboratory evaluation, there was no difference in tolerability between the two groups. Parasitologic evaluation at day 15 showed that 74.5% of the treated group had negative smears compared with 56.4% among controls (P = 0.06). This difference was no longer apparent at days 45 and 105. Clinical evaluation at days 15, 45, and 105 did not indicate any difference between the two groups. The clinical evaluation at day 15 was a good predictor of the final prognosis of the lesion in the two groups when analyzed separately, suggesting no clinical relapse in either group. These findings suggest that paromomycin ointment should not be used in the present formulation as a treatment for zoonotic cutaneous leishmaniasis in Tunisia.

Abstract
Colombian patients with New World cutaneous leishmaniasis were treated with a combination of a topical formulation (15% paromomycin sulfate/5% methylbenzethonium chloride, twice a day) and parenteral meglumine antimonate (20 mg of antimony [Sb]/kg.d]). Cohort 1 received topical therapy for 10 days and Sb for 7 days; 18 (90%) of the 20 patients were cured (follow-up, 12 months). Other clinical data suggested that neither the topical formulation alone nor the 7-day regimen of Sb alone would have cured many patients. In a subsequent cohort, which received topical therapy for 10 days and Sb for 3 days, the cure rate was 42% (eight of 19 patients). In Colombian cohorts (historical controls) treated with Sb alone for 10-15 days, the cure rate was 31%-36%. Side effects in cohort 1 patients consisted of local reactions to the topical formulation: burning and pruritus in 25% of patients and vesicle formation in 15% of patients. This is the first report that a regimen partially composed of topical antimicrobial agents can be highly effective for treatment of New World cutaneous leishmaniasis.

Abstract
OBJECTIVE To report a case of pancreatitis related to paromomycin administration. CASE SUMMARY A 39-year-old man with AIDS developed pancreatitis concurrent with successful treatment of intestinal cryptosporidiosis with paromomycin. The hyperamylasemia resolved with discontinuation of the agent and recurred when paromomycin treatment was reinstituted. DISCUSSION To our knowledge, this is the first reported case of pancreatitis believed to be induced by paromomycin. Although pancreatitis in HIV-infected patients has multiple causes, the nature of this case suggests the involvement of paromomycin. The mechanism of action is unclear. CONCLUSIONS Pancreatitis should be considered in the differential diagnosis of abdominal pain in patients who are treated with paromomycin.

Abstract
A 19-year-old male patient with chronic cutaneous leishmania is was treated topically with paromomycin sulphate (15%) and methylbenzethonium chloride (12%) in petrolatum album. After application twice daily for two periods of 32 and 44 days the lesions were completely healed. Previous treatment for 9 months with ketoconazole (400 mg/day) together with the topical application of thiabendazole (2.5%) in base had been unsuccessful. No major side effects were observed after paromomycin sulphate application.

Abstract
Ninety military patients with cutaneous leishmaniasis in Colombia were randomly allocated to 3 treatment regimens of parenteral aminosidine sulphate: (i) 12 mg aminosidine base/kg/d for 7 d, (ii) 12 mg/kg/d for 14 d, and (iii) 18 mg/kg/d for 14 d. With the 89 evaluable patients, the cure rates 12 months after the end of treatment were 10%, 45%, and 50%, respectively. Fifty-eight of the 66 patients who were not cured had lesions that enlarged or were unchanged by 1.5 months after treatment follow up. The other 8 patients had lesions that relapsed between 3 and 12 months after therapy. Even in group (iii) the cure rate was inferior to that (> 90%) with antimony or pentamidine previously reported in this patient population. This study indicates that parenteral aminosidine alone is less likely to be successful in the treatment of cutaneous lesihmaniasis than visceral leishmaniasis, for which a 74% cure rate has been reported. Further trials might consider the combination of aminosidine with other antileishmanial drugs.

Abstract
The efficacy of aminosidine was compared with sodium stibogluconate in an open, randomized study of parasitologically-proven cutaneous leishmaniasis in Belize. Aminosidine, 14 mg/kg/d (max. 1 g daily) for 20 d, healed 10 of 17 lesions and sodium stibogluconate, 20 mg/kg/d for 20 d, healed 15 of 17 lesions. Lesions caused by Leishmania braziliensis were relatively unresponsive to aminosidine. Aminosidine was well tolerated and toxicity was not observed. Sodium stibogluconate was not well tolerated and treatment was associated with bone marrow suppression and elevation of serum aminotransferases.

Abstract
A 15% aminosidine sulphate (AS)/10% urea/white soft paraffin (WSP) ointment cured all Leishmania major lesions on Balb/C mice following topical application for 10 d. Some relapses were observed 10 weeks after treatment. AS alone in WSP ointment was also highly effective. The ointment containing urea was non-irritant to mice, whereas ointments containing quaternary ammonium compounds were irritant. The 15% AS/10% urea/WSP ointment was not effective in the treatment of L. mexicana or L. panamensis lesions on Balb/C mice, no cure being observed.

Abstract
Cryptosporidiosis in patients with AIDS often leads to a severe wasting illness that is difficult to treat. Recent reports suggest that paromomycin may be useful in the treatment of intestinal cryptosporidiosis. We reviewed our experience using paromomycin for the treatment of cryptosporidiosis in seven patients with AIDS. All patients received paromomycin (500 mg orally every 6 hours) for an average of 11.7 days. The mean follow-up period was 3.2 months. All patients had an initial response to paromomycin that was characterized by a decrease in frequency of diarrheal episodes, stabilization of body weight, and/or eradication of cryptosporidia from the stool. The mean number of diarrheal episodes decreased from 10.9 to 1.7 daily. Stabilization or increase in body weight was noted for five of seven patients, and eradication of oocysts was documented for three patients. Relapses or recurrences were noted for three patients. Treatment with paromomycin was well tolerated by all patients with the exception of two, who experienced nausea and abdominal discomfort. Thus, paromomycin appears to be a promising agent for treatment of acute cryptosporidiosis.

Abstract
We report 11 patients with leishmaniasis from different endemic areas, treated in the UK with intravenous aminosidine alone or in combination with other drugs. Clinical and parasitological cures were achieved in all 7 patients from the Mediterranean zone who had visceral disease, with one relapse. Two of 4 patients with cutaneous or mucosal disease were cured; the other 2, from Iraq and Iran, did not respond. Toxic effects were high-tone deafness in 2 patients, one of whom had pre-existing renal impairment, and transient, mild elevation of serum creatinine in 3. Aminosidine is an effective, tolerable and relatively non-toxic alternative to existing antileishmanial drugs for the treatment of visceral leishmaniasis. Further studies will be needed to assess its place in cutaneous and mucosal disease.

Abstract
A prospective evaluation was made of the therapeutic efficacy of paromomycin, an orally administered, nonabsorbable aminoglycoside, in 114 homosexual men with mild-to-moderate (nondysenteric) intestinal amebiasis. All patients received 25-35 mg/kg daily in three divided doses for seven days. Of the 80 patients with gastrointestinal complaints at the onset of therapy, 55 (80%) of 69 were asymptomatic within four to six weeks after completion of treatment; 11 patients were lost to follow-up. Paromomycin produced long-term eradication of intestinal Entameba histolytica infection in 92% of all men evaluated. The rate of microbiologic cure among patients with symptoms at the onset of therapy was comparable to that among asymptomatic individuals. Paromomycin was well tolerated, with mild diarrhea during therapy the only frequent adverse effect (67% of patients). Thus, paromomycin is an effective alternative to conventional multi-drug therapy for intestinal amebiasis, and it has the advantages of low toxicity, brief duration of therapy, and a high rate of patient compliance.

Abstract
About 50 mg/kg of paromomycin sulfate was administered orally in a single or 2 divided doses to patients with Diphyllobothrium latum infections. The following results were obtained. After the treatment with paromomycin sulfate mature strobilae were expelled in all of 7 patients with Diphyllobothrium latum infections. We couldn't find scolices in all cases. Although these stools were examined for 2 months after the treatment, the eggs of Diphyllobothrium latum were not identified. No side effects were observed in all cases. It was concluded that paromomycin sulfate was effective on the treatment of Diphyllobothrium latum infections.

Abstract
Paromomycin sulfate (aminosidine) at a single dose of 32 to 53 mg/kg was orally given to 24 cases with proven diphyllobothriasis. Evaluation of efficacy of the drug was based on stool examination for the eggs after 3--4 weeks of treatment. The cure rate was obtained as 96% (23/24), and 30 worms were expelled from 24 patients. Only 1 unsuccessfully treated case of 34-year-old man was retreated at the same dose of the drug 3 weeks later to obtain the cure. Thirty worms were composed of a single worm each from 21 patients, 2 worms from a patient, 3 from 1, and 4 from 1. Scolices of 7 (23.3%) out 30 worms were found. Vomiting as side effect of the drug was observed in only a case of 4-year-old girl at 40 minutes after administration of the drug but it was mild and transient. Clinical symptoms or complaints before treatment were as follows; abdominal discomfort in 12 cases, abdominal pain in 7, diarrhea in 4, fatigue in 2, tinnitus, vomiting and frequent stool in 1 each. Seven cases were almost asymptomatic. Morphological changes of the worms immersed in paromomycin solution (aminosidine) (1.66 mg/ml) for 1, 2 and 3 hours were observed in comparison with worms kept in physiological saline solution. The destructive effects were fragmentation, dissolution and desquamation of the outer cuticle and basement membrane with PAS stain at 3 hours of the experiment. The damages were also demonstrated in subcuticular tissues composing of muscle layer and parenchymal cells.

Abstract
Recently it has been known that paromomycin sulfate had marked anthelmintic activity against some species of tapeworms. In this investigation, paromomycin sulfate was used for treating 6 cases of diphyllobothriasis and 1 case of Taenia saginata infection. Paromomycin sulfate was administered orally in a single dose or 2 divided doses of 40--60 mg/kg, being followed by a purge about 1.5 hours later. Strobila or fragments of proglottids were expelled from 5 cases, of which only 1 scolex was found in a case of infection with marine species of Diphyllobothrium. In 1 case of diphyllobothriasis no worm or worm-fragment was found in the stool even after the second challenge of treatment. Nevertheless follow-up examination for more than 1 month showed no evidence of remaining infection in all cases. Transient dizziness was observed in only 1 case, disappearing within about 30 minutes. Serum- and urine-examinations detected no abnormal signs in all cases excepting 1 case of diphyllobothriasis with suspected hepatitis. It was concluded that paromomycin sulfate is effective therapeutic agent for the treatment of taeniasis and diphyllobothriasis including marine species.

Abstract
Recently, it has been known that the aminosidine has marked anthelmintic efficacy against tapeworm. In this investigation, aminosidine was used for treating 14 cases with Ciphyllobothrium latum infection and 5 cases with Taenia saginata infection. Aminosidine was administered orally in a single dose of 50 mg/kg, followed by a purge after the treatment. Fourteen patients with D. latum infection and 5 patients with T. saginata infection expelled long strobila in all cases. Although only 7 scolices of 18 worms of D. latum were found in the stool and no scolex of T. saginata was found, follow-up examination for a long period showed no evidence of remaining infection with one exception of D. latum. Mild nausea, vomiting and abdominal pain were observed in only one of 19 cases given aminosidine. But in the other 18 cases, no side effects were encountered. It was concluded that aminosidine is safe, effective therapeutic agent for the treatment of cestodiasis in man.
