Abstract
Introduction: Tinea corporis (TC; ringworm or dermatophytosis) is a superficial skin infection caused by Microsporum, Epidermophyton and Trichophyton genera of dermatophytes. We compared the effects of individualized homeopathic medicines (IHMs) in fifty-millesimal (LM) potencies against placebo in TC.
Methods: A double-blind, randomized, placebo-controlled, two parallel arms trial was conducted on 62 individuals suffering from TC at the National Institute of Homoeopathy, India. Participants were randomized in a 1:1 ratio to receive either IHMs in LM potencies or identical-looking placebos for a period of 3 months. The primary outcome measure was the number of participants showing complete disappearance of skin lesions after 3 months. Secondary outcomes were a numeric rating scale (NRS) measuring intensity of itching and the Skindex-29 questionnaire (overall, and three sub-scales - degree of symptoms, psychological functioning, emotional status). All were assessed at baseline and every month, up to 3 months. The intention-to-treat sample was analyzed to detect inter-group differences using two-way repeated measures analysis of variance after adjusting for baseline differences.
Results: The primary outcome revealed no improvement in either of the groups (χ2 = 0.012, p = 0.999). Inter-group differences in some of the secondary outcomes favored IHMs against placebo - itching NRS (mean group difference after 3 months: -0.7 (95% confidence interval [CI], -1.1 to -0.4; p = 0.001); Skindex-29 overall (mean group difference after 3 months: 3.2 [95% CI, -0.6 to 7.0; p = 0.009]); Skindex-29 degree of symptoms (mean group difference after 3 months: 0.9 [95% CI, -0.2 to 1.9; p = 0.007]); and Skindex-29 psychological functioning (mean group difference after 3 months: 1.7 [95% CI, 0-3.4; p = 0.002]).
Conclusion: Results were negative on the primary outcome; however, secondary outcomes included some statistically significant results favoring IHMs against placebo after 3 months.
