“…Dermatophytosis is a frequent childhood disease, and the fungal species involved varies according to age and clinical presentation. 61 Tinea capitis is the primary clinical presentation of dermatophytosis in African children, as shown in many studies throughout the entire African continent, including West Africa, 13,[15][16][17][20][21][22]25,37,38,40,42,43 North Africa, 30,61,62,[68][69][70][71]77 East Africa, 32,33,84,86,88 Central Africa, 7,90,91 and southern Africa. 100,101,105 Many publications reported a high prevalence of dermatophytosis in West and North African children.…”

“…In contrast to studies concerning children, which were primarily conducted on populations of schoolchildren, the epidemiology of dermatophytosis among adults focused on patients of any age attending various healthcare facilities (such as university hospitals, dermatology departments, microbiology departments, dermatology clinics at medical center, or army hospitals) and in inmates. Adult-based studies concerned cases in West Africa, 12,22,23,28,34,36,38,40,45,55,57,58 North Africa, 35,[48][49][50][51][52]61,[63][64][65][69][70][71][72][75][76][77]79,106 Central Africa, 29,92 East Africa, 32,102 and southern African countries. 103,104 Some reports, regarding patients cared for in various healthcare facilities in West Africa, highlighted a higher prevalence of dermatophytosis in adults than in children.…”

“…35,50,51,63,72 In Egypt, a study found a relatively low prevalence (2%) of dermatophytes isolated from skin lesions in Egyptian adults of at least 55 years of age. 77 However, these estimations are impacted by a selection bias, as patients who are referred to tertiary healthcare facilities are unlikely to be representative of the general population. Noticeably, data on tinea pedis and onychomycosis in Africa are relatively scarce compared to other regions of the world.…”

In this critical literature review, we summarize the epidemiological trends of dermatophytoses reported in Africa. Our findings clearly emphasize the heavy burden of dermatophytosis in Africa. Tinea capitis is the primary clinical presentation of dermatophytosis in African children throughout the entire African continent. The disease affects more than 20% of school-age children in West Africa, while the prevalence ranges from 10% to more than 70% in other regions of Africa. In African adults, the presence of tinea corporis is the most frequent indicator of dermatophytosis. However, epidemiological studies have been primarily conducted on particular patient groups that are not representative of the general population. We examined dermatophyte species distribution patterns. We observed a predominance of anthropophilic dermatophytes, mainly T. violaceum, in the North and East of Africa and both T. soudanense and M. audouinii in the Western and Central regions of the continent. Interestingly, the zoophilic species, M. canis, has recently emerged in North and East Africa. Optimization of both mycology diagnosis capacities and epidemiological methodology would provide insight into the role that climate and other global aspects of the human environment play in dermatophyte epidemiology. We advocate that using a multisectoral and collaborative strategy would strengthen such future studies.

“…This is significantly higher than seen in healthy individuals as seen in some studies which show rates as low at 2-3%. 11 The most prevalent dermatophytic infection was tinea cruris with it being 44% of all dermatophytic infections. This was followed closely by tinea corporis consisting of 37% of the dermatophytic infections.…”

Cutaneous fungal infections in subjects with diabetes mellitus

Background: Diabetes mellitus is a chronic non-communicable disease causing an increase in blood glucose levels due to an ineffectiveness or insufficiency of secreted insulin. Infections have also been shown to be the most common skin changes in diabetics. In our study we aim to assess the susceptibility of diabetics to various superficial fungal infections. We will study candidiasis, tinea versicolor and dermatophytic infections in diabetics.Methods: 400 diabetic individuals who gave consent were chosen at random from the patients attending the OPD. They were subjected to thorough clinical evaluation. Routine hematological investigations were done. FBS, PPBS, and HBA1C were done to assess diabetic control. Fungal infections were confirmed by KOH mounts.Results: Of the 400 subjects 220 were male and 180 were female. 52.5% of the subjects had some fungal infections. 55.2% of the fungal infections were candidiasis. 27.6% of the fungal infections were dermatophytic infections. 17.1% of the fungal infections were tinea versicolor infections. Conclusions: The study has analysed the epidemiology of cutaneous fungal infections in diabetics. A little over half the diabetics studied proved to have cutaneous fungal infections. Candidiasis was the most frequent form of cutaneous fungal infections accounting for 57% of the fungal infections. Dermatophytic infections were seen in 28% of infections and pityriasis versicolor for 17% of the infections. This high prevalence of cutaneous fungal infections among diabetics merits systematic screening for the same among this target group.

“…Today the percent of opportunistic fungal infections is increasing, so when considering the role of skin as a reservoir from which infection of a susceptible host can occur, determining the fungal microbiome specially Candida is important [3]. Two of the most factors influencing the complex of inhabitants on the skin are gender [4] and age [5,6].…”
