Prevalence and Factors Associated with Self-Medication in Dermatology in Togo

Objective

This study aimed to determine the prevalence of and factors associated with self-medication in dermatology in Lomé, Togo.

Methods

We conducted an analytical cross-sectional study from February to April 2016 in 2 dermatology departments in Lomé. Univariate and multivariate logistic regression models were carried out to identify possible factors associated with self-medication.

Results

A total of 711 patients were included in the study. The mean age (±SD) of the patients was 26.6 ± 6.9 years and the sex ratio (male/female) was 0.6. The main dermatologic diseases recorded were immunoallergic dermatoses (39.7%) and infectious skin diseases (22.6%). Two-thirds (481/711; 66.7%) of the patients had practiced self-medication before consultation in dermatology units. In multivariate analysis, factors associated with self-medication were female sex (aOR = 1.44; 95% CI = [1.01, 2.05]), duration of dermatologic disease more than one year (aOR = 1.79; IC = [1.19, 2.68]), adnexal dermatoses (aOR = 2.31; 95% IC = [1.03–5.21]), keratinization disorders (aOR = 4.23; 95% CI = [1.36–13.13]), and fungal skin infections (aOR = 5.43; 95% CI = [2.20, 13.38]).

Conclusion

Our study confirms that self-medication practice is very common among patients with dermatologic diseases in Lomé and has identified associated factors.

Self-medication with steroids in inflammatory bowel disease

BACKGROUND

The self-prescribing rates of corticosteroids in inflammatory bowel disease (IBD) patients treated with biologicals are unknown.

AIM

To investigate the frequency and modalities of self-medication with steroids in adult IBD patients.

METHODS

Patients with IBD who attended Nancy University Hospital between November 2012 and May 2013 were included in the study. Patients were interviewed using an 11 item questionnaire.

RESULTS

100 patients participated in the survey. In total 15 patients (15%) had already used corticosteroids without medical prescription since their IBD diagnosis and 4 patients of them (27%) used steroids as self-medication while on anti-TNF treatment. The mean total duration of corticosteroid treatment was 24 days (range 1.5-105). In total 4 patients (27%) used corticosteroids more than 10 times without medical prescription (range 1-20). The two main reasons were the need for quick relief of symptoms (n=6) and the unwillingness to consult a physician (n=3).

CONCLUSION

A relatively high proportion of patients with IBD use corticosteroids without medical prescription. Due to their side effects, self-medication may include 'steroid dependency' as it may reflect uncontrolled disease. As steroids have significant side effects and patients may have active disease it is important to counsel patients and to monitor their self-prescribing patterns in IBD patients.

Prevalence of self-medication for skin diseases: a systematic review

Self-medication is the selection and use of drugs without medical prescription, to treat diseases or for symptomatic relief. This article is a systematic review on self-medication in skin diseases. A search was conducted on Virtual Health Library and PubMed databases using predetermined descriptors. Two researchers performed the article selection process independently, with the degree of inter-observer agreement measured by the kappa index. The prevalence of self-medication ranged from 6.0 to 45.0%. Topical corticosteroids were the most commonly used therapeutic strategies for self-medication, as found in the reviewed articles. This study revealed that published data on self-medication in dermatology are scarce, although the findings showed that it was a common practice.

[Fixed drug eruption in dermatology setting in Lomé (Togo): a retrospective study of 321 cases]

The aim of this study was to determine the frequency and list of drugs responsible for fixed drug eruption (FDE) in Lomé (Togo). A descriptive retrospective study of patients with FDE treated from January 2006 to November 2011 in dermatology service at the teaching hospital of Lomé (Togo) was conducted. During the study period, 321 cases of FDE were reported among 472 cases of toxidermia observed. Mean age of the patients was 31.27 ± 14.01 years and sex-ratio (M/F) was 1.01. One hundred thirty-three (41.4%) of 321 patients had a previous FDE, against 58.6% who were in their first attack. The most common form was the hyperpigmented form (247 cases/321). The main locations of the lesions were the trunk (N = 127) followed by the lower limbs (N = 85), the upper limbs (N = 81) and external genital organs (N = 53). A drug was incriminated in 163 (50.8%) of the 321 patients, in whom 109 patients took their drug by self-medication. Antibacterial sulfonamides were the first drug involved (70.5%), followed by nonsteroidal anti-inflammatory drugs (9.8%), antimalarial drugs (7.4%) and antibiotics (3.7%). All patients received a banned drug. In addition, 111 patients were treated with antihistamines, 69 with corticosteroids, and 58 with topical antiseptics. During follow-up, 42 of 321 patients have been seen; all had a favorable outcome. Our study confirms the frequency of FDE and the role of antibacterial sulfonamides as the cause of FDE in Africa and documents the effects of self-medication in toxidermia in Togo.
