A double blind, randomised placebo controlled trial of rifampicin with omeprazole in the treatment of human cutaneous leishmaniasis.

BACKGROUND & OBJECTIVES: This study was conducted on 50 patients of Anthroponotic cutaneous leishmaniasis (oriental sore) to assess the efficacy of rifampicin and omeprazole through a double blind, randomised placebo control study. METHODS: The diagnosis of Anthroponotic cutaneous leishmaniasis (ACL) caused by Leishmania tropica was done by demonstration of Leishmania tropica (LT) bodies from the painless, dry ulcerative lesion. Each patient was assessed clinically in the beginning of the study, at the end of 2,4 and 6 weeks and all observations were compared in both the groups. Twenty-five patients received rifampicin with omeprazole (Group A) whereas other 25 patients received placebo (Group B) for a period of six weeks. RESULTS: Altogether 23 cases in group Aand 21 cases in group B completed the study. About 16 (69.7%) cases in group A and 3 (14.29%) cases in group B had complete healing, whereas 3 patients (13.04%) of group A and 4 patients (19.05%) of group B had partial response and 4 patients (17.93%) of group A and 14 patients (66.67%) of group B had no response at the end of study. The difference of two groups was statistically highly significant (p < 0.00025). All patients tolerated the drug and placebo very well and no side effect was reported. INTERPRETATION & CONCLUSION: In our opinion rifampicin and omeprazole is a highly effective, less toxic and cheaper alternative for the management of cutaneous leishmaniasis.

Divalproex sodium in the management of post-herpetic neuralgia: a randomized double-blind placebo-controlled study.

BACKGROUND: Post-herpetic neuralgia is difficult to treat. Divalproex sodium (valproic acid and sodium valproate in molar ratio 1:1) has been used successfully in the management of various painful neuropathies. AIM: To study the effectiveness and safety of divalproex sodium in the management of post-herpetic neuralgia. DESIGN: Randomized double-blind placebo-controlled trial. METHODS: We enrolled 48 consecutively attending out-patients with post-herpetic neuralgia, out of whom three were excluded (two had insufficient pain, one withdrew consent). Quantification of pain was by Short Form-McGill pain questionnaire (SF-MPQ), visual analogue scale (VAS), present pain intensity score (PPI) and 11 point Likert scale (11 PLS) at the beginning of the study, after 2 weeks, 4 weeks and at the end of the study (8 weeks). We also assessed patients' global impression of change by questionnaire at the end of the study. RESULTS: After 8 weeks treatment with 1000 mg/day divalproex sodium, there was significant reduction in pain: SF-MPQ, 20.47 +/- 2.29 to 11.90 +/- 6.52 (p < 0.0001); PPI 4.0 +/- 0.52 to 1.95 +/- 1.29 (p < 0.0001); VAS 70.17 +/- 9.21 to 31.27 +/- 29.74 (p < 0.0001) and 11 PLS 6.97 +/- 0.73 to 3.63 +/- 2.34 (p < 0.0001) in comparison to placebo (means +/- SEM). The 'global impression of change' questionnaire showed much or moderate improvement in pain in 58.2% of patients receiving divalproex vs. 14.8% of those receiving placebo. The drug was well tolerated by all patients, except one who developed severe vertigo after 10 days of treatment. DISCUSSION: Divalproex sodium provides significant pain relief in patients of post-herpetic neuralgia, with very little incidence of adverse reactions. These data provide a basis for longer trials in a larger group of patients.

The role of rifampicin in the management of cutaneous leishmaniasis.

We assessed the efficacy of rifampicin in the treatment of cutaneous leishmaniasis (oriental sore) using a double-blind placebo-controlled study. We studied 46 patients with cutaneous leishmaniasis, of whom 23 received rifampicin (group A) and another 23 received placebo (group B) for a period of 4 weeks. Each patient was assessed clinically for size of lesion, type of lesion, duration of lesion, number of lesions, and distribution of lesions, initially, and at the end of 1 week, 2 weeks and 4 weeks. Biochemical tests including enzyme studies were done to detect any toxic effects of the drug. Group A patients received rifampicin 1200 mg/day in two divided doses and group B patients received two doses of an identical placebo capsule. Seventeen (73.9%) of the 23 patients receiving rifampicin had complete healing. Two (8.6%) had partial healing and four (17.3%) showed no response, whereas out of 23 patients receiving placebo one patient (4.3%) showed complete healing, eight (34.7%) patients showed partial healing and 14 (60. 98%) patients showed no healing or exacerbation of lesion. The difference was statistically significant in favour of response to rifampicin. This dose of rifampicin was well-tolerated and no side-effects were seen in any patient. In cases of cutaneous leishmaniasis where injectable treatment is not feasible or not acceptable, as in cases of multiple lesions, rifampicin is a better alternative oral treatment. It is simple to administer, cheap, more effective and less toxic than other available oral drugs, and well-tolerated by patients.

Oral zinc as an adjunct to dapsone in lepromatous leprosy.

Oral zinc was tried in 15 cases of multibacillary leprosy as an immunostimulant in addition to conventional antileprosy drugs. Results were compared with those in ten similar cases treated with dapsone alone. Cases treated with zinc showed faster clinical improvement, regrowth of eyebrows, rapid fall in the bacterial index (BI) and in the bacterial index in the granuloma (BIG), early and greater influx in lymphocytes in the granuloma, and neovascularization. Upgrading occurred in 6 out of 15 patients taking zinc, but in only 1 out of 10 patients in the control group. Five out of six patients who showed upgrading in the treated group became lepromin positive. Only one patient (BL) showed lepromin conversion in the control group.

Oral zinc in recurrent Erythema Nodosum Leprosum reaction.

Oral zinc sulfate was tried in Eight cases of recurrent Erythema Nodosum Leprosum. To control ENL, they required high dosage of clofazimine and steroids for prolonged periods. After instituting oral zinc, the dose of clofazimine could be reduced to 100 mg twice a week and steroids could be withdrawn completely. Four out of five patients who were not tolerating dapsone earlier, started tolerating dapsone. Incidence and severity of subsequent ENL was also reduced.

Amoebiasis cutis in HIV positive patient.

Protozoan infections of the skin, particularly cutaneous amoebiasis, are rare in HIV-positive patients. We report a case of amoebiasis cutis in an HIV-positive truck driver with a history of frequent unprotected sexual exposures. He presented with multiple painful ulcers and sinuses with purulent discharge, necrotic slough and scarring in the perianal and gluteal region for the last 2 years. He was positive for HIV-1 and -2. Cutaneous biopsy revealed numerous Entamoeba histolytica in the trophozoite form, in addition to an inflammatory infiltrate and necrotic debris. He responded well to oral metronidazole and chloroquine. Amoebiasis cutis should be considered in the differential diagnosis of perianal ulcers, particularly in HIV-positive patients.

Dermatoglyphics in leprosy.

In the present study, dermatolyphic parameters were analysed in the handprints of 25 LL/BL, 25 TT/BT and 25 healthy persons, by printer's ink method. Frequency of loops, were more on right hand and whorls were more on left hand in LL patients as compared to normal healthy controls. In TT the whorls were less frequent than in controls. The a-b ridge count in LL patient has shown insignificant difference from control while the same in TT was significantly decreased (P less than 0.05). Distance between distal wrist crease and axial triradius was significantly decreased in LL as compared to normal (P less than 0.05), whereas no such decrease was observed in TT patients.
