          Abstract

          Background

          The use of complementary and alternative medicine (CAM) is on the increase globally with a high prevalence in children and adults with chronic illnesses. Many studies have evaluated the epidemiology of medicine use for children in developing countries but none has evaluated the use of CAM for children with chronic illnesses. The aim of this study was therefore to determine the prevalence, pattern of use, parental sources of information, perceived benefits, cost, and adverse effects of CAM in children with epilepsy, sickle cell anaemia and asthma in Lagos, Nigeria.

          Methods

          Parents of children with epilepsy (122), asthma (78) or sickle cell anaemia (118) who presented consecutively to the paediatric neurology, respiratory and haematology clinics of the Lagos State University Teaching Hospital (LASUTH), Ikeja were interviewed with a structured open- and close-ended questionnaire. The information obtained comprised the demography of both the patients and their parents; past and present treatments received by the patients; the type of CAM, if any, used by the patients; and the sources, cost, benefits and adverse effects of the CAM used.

          Results

          A total of 303 CAMs were used by the patients, either alone or in combination witother CAM. CAM was reportedly used by 99 (31%) patients (epilepsy -38%, sickle cell anaemia – 36% and asthma – 25%). The majority (84%) of these patients were currently using CAM. The use of CAM was stopped six months prior to the study by 16 patients (16%). Biological products were the most frequently used CAMs (58%), followed by alternative medical systems (27%) and mind-body interventions (14%). Relations, friends and neighbours had a marked influence on 76% of the parents who used CAM for their children. Eighty-five (86%) parents were willing to discuss the use of CAM with their doctors but were not asked. CAM use was associated with adverse reactions in 7.1% of the patients.

          Conclusion

          Parental use of CAMs to treat their children with epilepsy, asthma and sickle cell anaemia is common in Nigeria. Efforts should be made by doctors taking care of these patients to identify those CAM therapies that are beneficial, harmless and cheap for possible integration with conventional therapy.

          Trends in alternative medicine use in the United States, 1990-1997: results of a follow-up national survey.

          A prior national survey documented the high prevalence and costs of alternative medicine use in the United States in 1990. To document trends in alternative medicine use in the United States between 1990 and 1997. Nationally representative random household telephone surveys using comparable key questions were conducted in 1991 and 1997 measuring utilization in 1990 and 1997, respectively. A total of 1539 adults in 1991 and 2055 in 1997. Prevalence, estimated costs, and disclosure of alternative therapies to physicians. Use of at least 1 of 16 alternative therapies during the previous year increased from 33.8% in 1990 to 42.1% in 1997 (P < or = .001). The therapies increasing the most included herbal medicine, massage, megavitamins, self-help groups, folk remedies, energy healing, and homeopathy. The probability of users visiting an alternative medicine practitioner increased from 36.3% to 46.3% (P = .002). In both surveys alternative therapies were used most frequently for chronic conditions, including back problems, anxiety, depression, and headaches. There was no significant change in disclosure rates between the 2 survey years; 39.8% of alternative therapies were disclosed to physicians in 1990 vs 38.5% in 1997. The percentage of users paying entirely out-of-pocket for services provided by alternative medicine practitioners did not change significantly between 1990 (64.0%) and 1997 (58.3%) (P=.36). Extrapolations to the US population suggest a 47.3% increase in total visits to alternative medicine practitioners, from 427 million in 1990 to 629 million in 1997, thereby exceeding total visits to all US primary care physicians. An estimated 15 million adults in 1997 took prescription medications concurrently with herbal remedies and/or high-dose vitamins (18.4% of all prescription users). Estimated expenditures for alternative medicine professional services increased 45.2% between 1990 and 1997 and were conservatively estimated at $21.2 billion in 1997, with at least $12.2 billion paid out-of-pocket. This exceeds the 1997 out-of-pocket expenditures for all US hospitalizations. Total 1997 out-of-pocket expenditures relating to alternative therapies were conservatively estimated at $27.0 billion, which is comparable with the projected 1997 out-of-pocket expenditures for all US physician services. Alternative medicine use and expenditures increased substantially between 1990 and 1997, attributable primarily to an increase in the proportion of the population seeking alternative therapies, rather than increased visits per patient.

            Herb-drug interactions.

            Concurrent use of herbs may mimic, magnify, or oppose the effect of drugs. Plausible cases of herb-drug interactions include: bleeding when warfarin is combined with ginkgo (Ginkgo biloba), garlic (Allium sativum), dong quai (Angelica sinensis), or danshen (Salvia miltiorrhiza); mild serotonin syndrome in patients who mix St John's wort (Hypericum perforatum) with serotonin-reuptake inhibitors; decreased bioavailability of digoxin, theophylline, cyclosporin, and phenprocoumon when these drugs are combined with St John's wort; induction of mania in depressed patients who mix antidepressants and Panax ginseng; exacerbation of extrapyramidal effects with neuroleptic drugs and betel nut (Areca catechu); increased risk of hypertension when tricyclic antidepressants are combined with yohimbine (Pausinystalia yohimbe); potentiation of oral and topical corticosteroids by liquorice (Glycyrrhiza glabra); decreased blood concentrations of prednisolone when taken with the Chinese herbal product xaio chai hu tang (sho-salko-to); and decreased concentrations of phenytoin when combined with the Ayurvedic syrup shankhapushpi. Anthranoid-containing plants (including senna [Cassia senna] and cascara [Rhamnus purshiana]) and soluble fibres (including guar gum and psyllium) can decrease the absorption of drugs. Many reports of herb-drug interactions are sketchy and lack laboratory analysis of suspect preparations. Health-care practitioners should caution patients against mixing herbs and pharmaceutical drugs.

              The prevalence of complementary/alternative medicine in cancer: a systematic review.

              Complementary/alternative cancer treatments are believed to be prevalent. However, reliable prevalence rates do not exist. The aim of this review was to summarize the existing data on this topic. A series of computerized literature searches was performed to locate all published studies documenting the prevalence of complementary and/or alternative therapy (CAM) use among patients with cancer. A total of 26 surveys from 13 countries, including 4 studies of pediatric patients, was retrieved. The use of CAM therapies in adult populations ranged from 7-64%. The average prevalence across all adult studies was 31.4%. This large degree of variability most likely is due to different understandings of "complementary/alternative medicine" on the part of both investigators and patients. It is likely that the results of the current study reflect the primarily adjunctive use of CAM treatments. Future studies should use a standardized protocol to determine the true prevalence of these therapies more closely.
