Comparison of Meglumine Antimoniate and Miltefosine in Cutaneous Leishmaniasis.

OBJECTIVE: To compare the efficacy and safety of meglumine antimoniate and miltefosine in the treatment of cutaneous leishmaniasis in Pakistan. STUDY DESIGN: Randomised-controlled trial. Place and Duration of the Study: Department of Dermatology, Combined Military Hospital, Lahore and Peshawar, from January to December 2021. METHODOLOGY: Smear positive and/or skin biopsy-confirmed cases of cutaneous leishmaniasis in adult males aged between 18-60 years were enrolled after receiving informed consent. Patients were randomly divided into Group A and Group B by lottery method. Group A received intramuscular meglumine antimoniate 15-20mg/kg/day, and Group B received oral miltefosine 50 mg thrice a day for a duration of 28 days. Data were analysed by SPSS 22. Effectiveness and safety of therapeutic agents were calculated by Independent t-test and p-value of 0.05 or less was taken as significant. RESULTS: Sixty-six patients, 33 in each group, participated in the study. Total number of cutaneous leishmaniasis lesions were 77 in Group A and 76 in Group B. The duration of lesions was 3.5 months in Group A and 3.2 months in Group B. Treatment response, in terms of complete or near complete resolution of lesions, was significantly higher in Group A as compared to Group B (p = 0.011). Both therapeutic agents had considerable side-effects with more patients withdrawn from Group A as compared to Group B (p = 0.010). CONCLUSION: Intra-muscular meglumine antimoniate was more effective in comparison to oral miltefosine in the treatment of cutaneous leishmaniasis. However, efficacy of meglumine antimoniate is mired by its side-effect profile.

Comparison of the Efficacy of Tap Water Iontophoresis Versus Aluminum Chloride Hexahydrate in the Treatment of Palmoplantar Hyperhidrosis.

OBJECTIVE: To compare the efficacy of tap water iontophoresis (TWI) versus aluminum chloride (AC) hexahydrate in the treatment of palmoplantar hyperhidrosis. METHODS: The study was a randomized control trial performed at the dermatology department of Pakistan Navy Station (PNS) Shifa Hospital, Karachi from March 2022 to September 2022. A total of 70 palmoplantar hyperhidrosis patients were included in the study after getting approval from the ethical committee. Patients were divided into two groups. Group A patients were treated with TWI three times a week for four weeks. Group B patients were treated with a 20% AC topical solution applied at night to the affected areas for four weeks. The Hyperhidrosis Disease Severity Scale (HDSS) score for both groups was calculated at baseline, one, two, three, and four weeks. The final response was labeled at four weeks by comparing mean HDSS reduction in both groups. SPSS version 28 (IBM Corp., Armonk, NY) was used for data analysis. RESULTS: Mean HDSS was compared for both groups at the end of the study, which showed a significant reduction in the mean score from 3.40 ± 0.65 to 1.48 ± 0.78 in group A, as compared to a decline in scores in group B from 3.28 ± 0.67 to 2.14 ± 0.94 (p = 0.002). In group A, zero, one, two, and three points HDSS improvement was 2.9%, 25.7%, 48.6%, and 22.9%, respectively. Whereas in group B, it was 34.3%, 22.9%, 34.3%, and 8.6%, respectively (p = 0.001). CONCLUSION: As compared to AC topical solution, TWI is an effective, safe, and inexpensive management option for palmoplantar hyperhidrosis. It causes more improvement in HDSS scores and has lesser side effects.
