Treatment of vertigo with a homeopathic complex remedy compared with usual treatments: a meta-analysis of clinical trials.
ABSTRACT The increasing interest in alternative medical practices has led to a number of controlled studies on herbal and homeopathic agents. This paper presents the results of a meta-analysis of four recent clinical trials evaluating the homeopathic preparation Vertigoheel (VH) compared with usual therapies (betahistine, Ginkgo biloba extract, dimenhydrinate) for vertigo in a total of 1388 patients. Two trials were observational studies and the other two were randomised double-blind controlled trials. The duration of treatment (6-8 weeks) and dosage were comparable in all studies. Treatments were evaluated for the variables "number of vertigo episodes", "intensity of episodes" and "duration of episodes". As the studies differed in the age of patients and in the baseline values of vertigo, the individual reductions of number, intensity and duration of episodes were adjusted on equal age and baseline values (total means). An analysis of variance (with studies as random effects) showed no relevant influence of studies on the adjusted reductions and no relevant interaction between studies and treatment effects. The meta-analysis of all four trials showed equivalent reductions with VH and with control treatment: mean reduction of the number of daily episodes 4.0 for VH and 3.9 for control (standard error 0.11 for both groups); mean reduction of the duration (on a scale 0-4) for VH 1.1 and for the control 1.0 (standard error 0.03 for both groups); mean reduction of the intensity (on a scale 0-4) for VH 1.18 and for the control 1.8 (standard error 0.03 for both groups). In the non-inferiority analysis from all trials, VH was non-inferior in all variables. The results show the applicability of meta-analyses on the data from studies with homeopathicdrugs and support the results from the individual studies indicating good efficacy and tolerability of VH in patients with vertigo.

ABSTRACT: Background In endemic areas, gestational malaria is responsible for low birth weight and maternal anaemia. Quinine is the reference treatment for acute malaria in pregnant women, irrespective of term. However, quinine administration is associated with various side-effects. We evaluated the impact of the homeopathic medicine China rubra 7CH on the side-effects of quinine used as treatment for acute malaria in pregnant women in Cotonou, Benin. Methods This prospective, comparative, randomised study was carried out between June and December 2007 in the Saint Jean-Baptiste Medical Centre, Cotonou. Women were included if they were >3 months pregnant and had a clinical diagnosis of malaria confirmed by a positive thick blood smear. The study population was divided into two groups: (i) patients who presented between the 1st and 15th of each month and who received China rubra 7CH plus quinine (China group); and (ii) patients who presented from the 16th to the end of each month and who received treatment with quinine only (Standard group). The aim was to compare the frequency of side-effects of quinine in the two groups until day 6 after the start of treatment. Neither the patients nor the care givers were blinded to study treatment. Statistical comparison of the two groups was carried out with an alpha risk fixed at 5%. Results 211 women were recruited: 105 received quinine plus China rubra 7CH (China group) and 106 received quinine only (Standard group). A decrease in proportion of patients presenting with side-effects was observed in the China group from day 0 to day 6 of follow-up (53.9%–23.3%) whereas the proportion of patients with side-effects in the Standard group did not change significantly (85.9% on day 0 vs. 82.5% on day 6). Ninety-six (72.4%) patients in the China group and 103 (97.2%) in the Standard group reported at least one side-effect during follow-up (p < 0.0001). The most frequently reported side-effects were tinnitus, dizziness and asthenia. Conclusions This preliminary study shows the interest of China rubra 7CH in limiting the side-effects of quinine used for the treatment of acute malaria in pregnant women.Homeopathy 07/2014; 103(3).
