Background: Candida spp is the most common superficial fungal infection in immunocompromised patients. With the advent of wide spectrum of immunosuppressive drug and increase in HIV patients, there is a change in the epidemiology and clinical presentation of mucocutaneous candidiasis.

Aim and Objective: This study has been designed to study epidemiology and the common clinical patterns of mucocutaneous candidiasis in immunosuppressed patients.

Materials and methods: A cross sectional study on epidemiology and clinical patterns of mucocutaneous candidiasis among 100 immunosuppressed patients of all age groups attending Dermatology OPD in a tertiary care center.

Results: Maximum number of patients were in third and fourth decade. Females were more frequently (73%) affected than males (27%). Type 2 diabetes was the most common cause of immunosuppression followed by steroid intake (20%), cancer patients (10%) and HIV (5%). Oral candidiasis was the frequently observed clinical pattern (48%) followed by vulvovaginal candidiasis (45%), intertriginous lesions on the fingers (2%), toes (2%), and neck (1%). Balanoposthitis was observed in 2% of patients.

Limitation: small sample size.

Conclusion: Diabetes was the common cause of immunosuppression. Oral candidiasis was the common clinical pattern observed among them.

Introduction

Candida is a normal commensal in the oral cavity, gastrointestinal tract and the reproductive system. Patients with defective cell mediated immunity develop only mucocutaneous disease whereas dysfunction of neutrophils leads to systemic involvement. The clinical spectrum of candidiasis is extremely varied, ranging from acute, subacute, chronic and episodic [1,2]. Involvement may be localized to skin and mucosa or it may be systemic as in septicemia, endocarditis and meningitis. The pathologic response evoked is diverse and vary from irritation and inflammation to chronic and acute granulomatous response [2,3].

Materials and Methods

The study was conducted among patients attending the OPD, Mycology section of the Department of Dermatology in a tertiary care centre in India. Immunosuppressed individuals of all age groups were included in the study. A total of 100 randomly selected immunosuppressed patients with symptoms and signs of mucocutaneous candidiasis were included in the study. Patients who were on immunosuppressive drugs and various systemic diseases were included in the study. Patients who were on systemic antifungals for more than 4 weeks and topical antifungals for more than 2 weeks were excluded from the study. Specimens from mucosal and skin scrapings were examined in 10% KOH for the presence of spores, hyphae and pseudohyphae. Inoculation was done in Sabouraud’s dextrose agar and observed for growth of candida which appeared as cream colored smooth colonies with yeasty odor (Figure 1).

Results

We observed in our cohort a mean age of 41.5 years (age range 1 month-70 years). Age wise distribution is shown in table 1. There was a female predominance with 73% (n=100) and males were 27% (M:F ratio 1:2.7) . Maximum number of females were in the age group of 31-40yrs and maximum number of males were in the age group of 41-50 yrs. Of the 100 immunosuppressed patients, type 2 diabetes was the most common cause of immunosuppression. 20% were on long term steroids for pemphigus vulgaris, bullous pemphigoid, Systemic lupus erythematoses, multicentric reticulohistiocytosis, pustular psoriasis and post renal transplant state. Two of them had chronic renal failure, 10% were on chemotherapeutic drugs and 5% were HIV patients. All diabetic patients had their random blood sugar level in the range of 200-290 mg/dl. The diabetic status of 50% of patients were on steroids induced. Most common clinical pattern observed was oral candidiasis (48%) followed by vulvovaginal candidiasis (45%). Intertriginous lesions in various sites like finger webspaces (2%), toe webspaces (2%) and neck (1%). Balanoposthitis was found in 2% of the patients. Among the oral candidiasis patients, pseudomembranous pattern was the most common type in 20 patients followed by angular chelitis (perleche) in 15 patients, acute erythematous type in 8 patients [Figures 2,3]. A single patient with multicentric reticulohistocytosis who was on prolonged steroids initially presented with acute erythematous type of oral candidiasis and subsequently developed esophageal candidiasis. Acquired immunodeficiency disorder was found in 3 patients of which 2 patients had pseudomembranous type and one patient had perleche. Balanoposthitis and intertriginous lesions were exclusively found in type 2 diabetes patients [Figures 4,5] . All cancer patients on chemotherapy developed oral candidiasis. Among the 10 cancer patients 5 had leukemia, other 3 had carcionoma breast and one had carcinoma cheek.

Discussion

Candidiasis can affect all age groups. Immunosuppressed patients developed candidiasis more than the immunocompetent individuals [4,5]. Safia et al., Reeding et al., proposed diabetes to be the predisposing factor for various fungal infections especially Candida spp [6,7].

Oral candidiasis has been observed the most common manifestation of mucocandidiasis in this study [3,8]. All patients with oral candidiasis had type II diabetes and their blood sugar levels were between 200-290 mg/dl. Tapper Jones et al, Aly et al., and Abu Elteen et al., reported the prevalence of yeast carriage in diabetic individual to reach upto 54% [9-12]. The relationship between the blood glucose level and carriage rate of Candida is controversial. Hill et al., proposed that long duration of diabetes rather than diabetes by itself puts the patient at risk of oral candidiasis [13]. Gray et al., proposed that there is no correlation between glycemic level and the Candida carriage rate [14]. Yet another study by Lamey et al., showed the lack of association between HbA1c or blood glucose level and the Candida carriage rate [15]. Similar reports were also given by Kumar et al., who stated that glycemic control and antidiabetic drugs have no correlation with the Candida carriage [16]. Oral candidiasis in pemphigus patients occurred as a complication of steroids. Pemphigus was shown to be associated with oral candidiasis in 24% in a study by Shaheen et al. [3]. All three HIV patients with oral candidiasis had their CD4 counts were between 374-400 cells /mm3. Bodhade et al., and Campo et al., proposed that oral manifestations were common in HIV patients with CD4 counts less than 200 cells /mm3 [17-19]. The presence of oral candidiasis in HIV patients in this study could be due to other contributing factors like poor oral hygiene and the prolonged use of antibiotics for prevention of opportunistic infection [20,21]. The number of patients in this study is small to establish a correlation with the CD4 count and the severity of oral candidiasis. Similar to our study leukemic patients developed candidiasis more frequently than other carcinoma patients. All patients were treated with topical and systemic antifungal drugs.

In summary, with increasing use of immunosuppressive agents and higher incidence of cancer candidiasis has become common fungal infection. Moreover it has increased the fatalities among bone marrow recipients.
