Background: Vitiligo is one of the most common dermatological illnesses with localized depigmentation leading to cosmetic impairment. This also causes impairment of physical, psychological, social functioning of individual which in turn leads to psychiatric morbidities such as anxiety and depression. Aims and Objective: The present hospital based study was carried out to evaluate the presence of depression in patients of vitiligo patients in their different socio demographic variables. In addition, attempts were made to measure the severity of depression in those patients. Material and Methods: This was a hospital based cross-sectional study. Eighty patients of vitiligo with lesions in the exposed body parts were enrolled for the study after their informed consent with purposive sampling method from the Department of Dermatology, in a tertiary care hospital in north eastern part of India and compared them with those of healthy control. Those patients were evaluated by using ICD-10 research criteria and 17 item Hamilton rating scale of depression to diagnose and grade the degree of depression. Data were collected and “Chi Square Test” or “Fisher Exact t Test” was used. Mean value and standard deviation were calculated. All analysis were done using SPSS version 20.0. Results: Co morbidity of depression was significantly higher in vitiligo group (23.75%) in comparison to control group (6.25%). Among the depressed patients 68.43% had mild depression and 31.57% had moderate depression. Depression was inversely proportional to the years of education. Conclusions: These findings indicate the need of early recognition of depression among these patients and their early intervention, which will improve the primary disease process positively.

| Introduction|| |
Vitiligo, a chronic dermatological disorder, is characterized by hypopigmentation or depigmentation of the skin and mucosa. It is an acquired condition resulting from the progressive loss of melanocytes. It is characterized by milky-white sharply demarcated macules. Its prevalence reaches 0.5%–2%, worldwide. Vitiligo equally affects males and females as well as all the different races worldwide., Vitiligo has a varied age of onset, distribution pattern, and progression course. The mean age of onset is about 20 years, and 95% of cases are under the age of 40.
Depigmenting dermatosis, of which vitiligo is one, draws unusual attention to the patient especially when in visible areas of the body. This cosmetic impairment often leads to social and sexual embarrassment, which often perceived as discrimination or rejection. The bewildered person already psychologically disturbed by his skin changes finds himself an object of unnecessary public focus because of this impairment. Vitiligo, as a result of its visibility and chronicity, may cause a significant burden on patients' health-related quality of life leading to many psychiatric disorders such as anxiety and depression. Multiple observational studies have suggested an epidemiological link between vitiligo and psychiatric morbidity such as depression.,
The complex interrelationship between mind and skin has been investigated at both molecular and cellular levels. It has been recorded that patients with chronic illness suffer more often from a major depressive illness and vice versa.,, When it comes to the association between vitiligo and depression, a bidirectional relationship is seen. The neuro-immuno-cutaneous-endocrine model was proposed by O'Sullivan et al. to explain the mind and body relationship. It forms the basis of many inflammatory cutaneous dermatoses like vitiligo that are triggered or exacerbated by psychological factors. Genetic studies have supported the correlation between emotional stress and autoimmune markers in vitiligo patients. Increased levels of heat shock protein 70, which is a stress protein, have found to be increased many autoimmune diseases like vitiligo.
Previous workers evaluated psychiatric symptoms such as depression, anxiety, and alcoholism in patients with vitiligo and had documented a higher prevalence of depression in those patients., Another study in India showed that the prevalence of depression in vitiligo was 20%.
In India and particularly in the northeastern part, a limited number of studies were done regarding this subject. Hence, an attempt has been taken to find the prevalence and severity of unipolar depression in vitiligo patients from this specific sociocultural and geographical background as well as its association with the different sociodemographic variables of these patients.
Aims and objectives
The aim of the study was to assess the prevalence and severity of unipolar depression in patients with vitiligo and also to assess the association of depression with the different sociodemographic variables in these patients.
| Subject and Methods|| |
This was a hospital-based cross-sectional study. The sample was drawn with a purposive sampling method from the outpatient department (OPD) of dermatology of a tertiary care hospital, in the northeastern part of India from July 2019 to November 2019.
Mode of selection of cases
After obtaining informed consent, eighty vitiligo patients of the age group of 18–60 years of both sexes were included. Only patients affected in their exposed parts of the body were selected for the study. Patients with present or past history of any major physical or dermatological illness other than vitiligo were excluded from the study. Patients with present psychiatric disorder other than unipolar depression and a history of any psychiatric disorder before the onset of vitiligo were also excluded from the study. Patients with bipolar depression and with a family history of any type of bipolar disorder were too excluded from the study. Pregnant and lactating women were excluded as depression is commonly seen in pregnancy and the postpartum period. Patients on systemic steroid, retinoids (isotretinoin, and acitretin), and on substance dependence were excluded from the study.
After obtaining institutional ethics committee approval, clinically diagnosed vitiligo patients were selected from dermatology OPD with a purposive sampling method as per inclusion and exclusion criteria. After obtaining informed consent, the mental status examination was done. Then the International Classification of Mental and Behavioral Disorders (ICD-10) research criteria along with 17-item Hamilton Rating Scale of Depression (HAM-D) were applied to diagnose the presence of depression and grading them as mild, moderated, severe, and very severe.
Mode of selection of controls
The control group comprised eighty attendants of patients attending dermatology OPD and indoor without any dermatological illness with same exclusion criteria. They were demographically matched with the study group. Controls were subjected to the same tools.
Description of tools
- Specially designed pro forma was used to record the sociodemographic data, which included present, family, medical, and drug histories; and also physical examination, as designed by the researchers
- Depression was diagnosed and assessed by the International classification of mental and behavioral disorders (ICD-10) tenth revision Research criteria
- 17-item HAM-D assessed the severity of depression. Items are scored between 0 and 4 points. A score of <7 has no depression (0-7); mild depression (8-16); moderate depression (17-23); and severe depression (≥24).
Analysis of data
Data were tabulated showing sociodemographic distribution between depressed and nondepressed patients. Chi-square test was administered to compare between the groups. Student's t-test was done to compare the mean values. All the statistical analyses were performed using Microsoft Excel software and the Statistical Package for the Social Sciences (SPSS for Windows, version 20.0. SPSS Inc., Chicago, IL, USA). P < 0.05 was taken as statistically significant in all aspects.
| Results|| |
In our study, 23.75% of the patients of vitiligo were depressed, whereas only 6.25% in the control group were depressed (P < 0.004) [Table 1]. The sociodemographic profiles of both depressed and nondepressed patients were compared. Depression was significantly prominent among the school dropout group means up to high school studied people (P = 0.034 i.e. <0.05), whereas other items in sociodemographic profile did not have statistically significant difference [Table 2].

On applying HAM-D in cases fulfilling the ICD-10 criteria for depression, it was found that 68.42% had mild depression, whereas 31.57% had moderate depression [Table 3]. Furthermore, the mean depression score (HAM-D) in cases was significantly higher (8.20 ± 3.99) than the control group (3.26 ± 1.91) (P < 0.0001) [Table 4]. Mild depression was more in case of males (53.84%), whereas moderate depression was more in females (83.33%) [Table 5]. The mean HAM-D score in females (8.60 ± 3.73) was found to be higher than that of the males (7.50 ± 2.72).

| Discussion|| |
In our study, the prevalence of depression diagnosed as per ICD-10 research criteria in vitiligo patients and the control group was 23.75% and 6.25%, respectively, which was statistically significant (P < 0.05). The higher rate of depression in vitiligo as in our study was similar to the previous studies., The reason for a higher rate of depression in vitiligo patients could be due to low self-esteem, embarrassment for self and family, and fear of social rejection which leads to impairment in vocational and social function. This disability resulted from stress (disease-related stress), cosmetic impairment, and social stigma.
Out of the eighty patients with vitiligo, majority of patients (38.8%) were in the age group of 18–27 years. The mean age in the study group was 33.3 years, and in the control group, it was 36 years. This was in concordance with the earlier study. Regarding gender, we found that there is a high incidence of vitiligo cases in females. In our study, 60% of the cases are female [Table 2] and 40% were male. Our study was in concordance with other studies.,, While comparing the prevalence of depression between genders, it was found that 57.89% of females and 42.10% of males were depressed. Hence, the females were more depressed compared to males. The mean HAM-D score in females (8.60 ± 3.73) was found to be higher than that of males (7.50 ± 2.72). Our findings were in accordance with previous studies.,,
In our study, we have found that highest percentage of our patients were married, i.e. 71.25%, and they were more depressed (63.42%) compared to the single patients (36.57%). Married patients, particularly females, might face more stigmatization and poor social support. Furthermore, discrimination toward females might be the reason for higher depression, however difference in our study was not statistically significant.,
Our study showed that 16 out of 19 depressed patients were either illiterate or studied up to high school level, i.e. school dropout who studied up to high school level and illiterate patients. Only 3 out of 19 patients had studied up to higher secondary or graduate level. We found a significant association between educational status and depression (P < 0.05). Thus, it was found that depression had an inverse relationship with the number of years of education. Our study was in accordance with previous studies., This might be due to the fact that with increasing education level, people can understand the nature of the disease and can cope better with the stress and anxiety and also can react in a more mature way to the social stigmatization. Regarding occupation, we found that housewives were suffering more from depression (31.57%) compared to any other groups. This was also in accordance with our earlier finding that married females with vitiligo suffer more from depression.
After applying HAM-D on these 19 patients who were depressed as per ICD 10 criteria, we found that 13 cases (68.42%) were having mild depression, whereas 6 patients (31.57%) had moderate depression. No patient was having severe depression [Table 3]. In the control group, only five participants who were depressed were having mild depression. Hence, we found that the severity of depression was also more in vitiligo patients than healthy controls. Furthermore, the mean depression score (HAM-D) in the study group was significantly higher than (8.20 ± 3.99) the control group (3.26 ± 1.91). Our finding was in accordance with previous studies [Table 4].,, When comparing the severity of depression between males and females, it was found that 83.33% of females had moderate depression compared to 16.66% of males. Hence, the severity of depression was also more in females compared to males [Table 5].
The limitations of the study were small sample size, and the patients were evaluated only once. Larger sample size and further evaluation would have been helpful to elicit the presence of depression in the course of illness. In addition, the study did not include the duration of vitiligo and their association with depression. Furthermore, this study did not take measurement of area involved in the body as only patients with vitiligo in their exposed body parts were included.
| Conclusion|| |
Depression was found to be associated with vitiligo at a significant rate and with mild-to-moderate grades of severity. Depression was more common in younger age, female gender, married patients, housewives, and people with lower education level. Thus, this association of depression with vitiligo needs early diagnosis and intervention which will help in better treatment of the vitiligo patients. This will improve the prognosis and quality of life of these patients.
Thus, vitiligo patients should be assessed with more holistic approach. We should account both physical and psychological aspects of these patients, and there should be good collaboration between dermatologists and psychiatrists to treat such patients for better prognosis of the patients.
