Comparison of quality of life evaluated by SF-36 and DLQI in multibacillary and paucibacillary leprosy patients from Sao Paulo, Brazil.

BACKGROUND: Dermatological diseases have a negative impact on quality of life (QoL), affecting mental and physical health. Leprosy patients usually present with a worse QoL compared with those affected by other conditions. Reactions, neural damage, and pain are some of the consequences that contribute to the lower QoL. However, due to the wide spectrum of the disease, symptoms vary according to leprosy's subtype. This study aimed to compare the QoL between paucibacillary and multibacillary leprosy patients. Individuals were also compared considering the presence of reactions and a correlation between questionnaires was performed. METHODS: A total of 104 patients with leprosy aged 18 years old and over were selected. QoL was assessed by the Brazilian-Portuguese validated versions of the Medical Outcomes Study 36-item short-form health survey (SF-36) and the Dermatology Life Quality Life Index (DLQI). RESULTS: Multibacillary patients showed a more impaired physical function, worse bodily pain, lower score of SF-36, and higher interference of skin on the performance of daily activities when compared to the paucibacillary group. Individuals without reactions presented lower bodily pain and less effect of the skin on clothing choices compared to those with reactions. The SF-36 domains exhibited weak correlations with most DLQI questions, and the linear regression model showed that 32% of changes in QoL were related to the skin aspect. CONCLUSIONS: Multibacillary leprosy patients have a worse QoL when compared to paucibacillary patients. Reactions played a small role in the QoL of our cohort of patients.

Pain and quality of life in leprosy patients in an endemic area of Northeast Brazil: a cross-sectional study.

BACKGROUND: Pain emerges as a challenge in the treatment of leprosy patients. In this study, we describe the prevalence and type of pain in patients with leprosy, and its effect on patients' quality of life in an endemic area of Northeast Brazil. FINDINGS: A cross-sectional survey of 260 patients attending leprosy reference centres in Sergipe, Northeast Brazil was conducted. Individuals were assessed for the presence and type of pain, skin sensory loss, peripheral nerve enlargement, touch and pinprick sensations, mechanical allodynia and nerve palpation. Participants completed the Douleur Neuropathique 4 questionnaire, and we also used the Brief Pain Inventory scale and the World Health Organization Quality of Life-BREF instrument to arrive at our results. One hundred and ninety-five (75 %) patients reported pain, mostly of the neuropathic type. Pain was moderate in 84 (43.1 %) and severe in 94 (48.2 %) participants. The presence of pain was associated with disability (p = 0.001), leprosy reactions (p = 0.004) and lower quality of life. Most patients with neuropathic pain were treated with steroids, despite their low efficacy for this type of pain. CONCLUSION: Pain is highly prevalent among leprosy patients and is associated with low quality of life. Leprosy management should include a systematic assessment of the type of pain a patient experiences in order to provide adequate treatment.

Dermatology life quality index in Thai patients with systemic sclerosis: a cross-sectional study.

BACKGROUND: Systemic sclerosis (SSc) is a multisystem disorder that affects various organ systems. Although SSc patients have both physical and psychological illness, psychological distress is sometimes underestimated as most physicians usually pay more attention to physical problems. AIMS: To evaluate dermatology-specific health-related quality of life (QoL) in Thai patients with SSc. METHODS: SSc patients, who attended the Department of Dermatology, Siriraj Hospital, Bangkok, Thailand, between August 2009 and April 2010, were enrolled. The demographic data and skin manifestations of the patients were recorded. Skin thickness of each patient was analyzed by modified Rodnan skin score. QoL was evaluated by using the validated Thai version of dermatology life quality index (DLQI) questionnaire. RESULTS: A total of 80 patients of SSc were enrolled in this study. Twelve patients had limited SSc, while 68 patients had diffuse SSc. The mean (SD) disease duration before period of evaluation was 9 (12.8) years. The mean total of DLQI score was 6.3 (range, 0-23). Patients with low DLQI score have longer disease duration than patients with high DLQI score (P<0.05). Pain/pruritus was the most significant problem to the patients. Salt and pepper appearance was the cutaneous finding that had association with high DLQI score. CONCLUSIONS: SSc had moderate impact on patient's dermatology-specific health-related QoL. Pain, pruritus, and obvious skin findings caused a significant impairment to SSc patients. Therefore, the treatment of pain and pruritus and prominent cutaneous findings should be taken into account to improve QoL of SSc patients.

An assessment of emotional pain among subjects with chronic dermatological problems in Lagos, Nigeria.

BACKGROUND: In dermatology, it is known that there is a significant co-morbidity between dermatological disorders and psychological complications, and it has been estimated that in at least one-third of patients with skin diseases, their effective management involves consideration of associated emotional factors. In Africa, particularly Nigeria, despite the prevalent dermatological disorders with their possible attendant mental health complications, little or no work has been done in the field of psycho-dermatology, hence the rationale for this study. METHODS: A prospective study was carried out in the dermatology/venerology clinic of Lagos University Teaching Hospital (LUTH). Ethical clearance and consent were obtained to conduct the study. The subjects were selected by simple random sampling from adult patients that have had their dermatological disorders for at least six months before presentation in the clinic. Those with other co-existing chronic medical illness such as hypertension, diabetes, or haemoglobinopathy were excluded from the study. Controls were obtained to match for age and sex from apparently healthy workers in a nearby general hospital. Each subject was evaluated with a questionnaire to obtain necessary socio-demographic data: Psychache scale (PAS), and subscales C, D, and J of Symptom Check List (SCL-90). The data generated was analyzed to obtain means, and t-test was used to compare the means; p = 0.05 was taken as being significant. The analyses were done using SPSS version 10. RESULTS: Eighty subjects with dermatological disorders, and of equal sex distribution, were evaluated, with mean age of 33 +/- 12.1 years. Equal number of controls matched for sex and mean age of 34.6 +/- 7.3 years were also evaluated. Among the subjects, 16.3% had Acne, followed by Urticaria (13.8%), Vitiligo (12.5%), Tinea (11.3%), Hansen's disease (5%), and others (41.1%). From assessment with PAS and SCL subscales, the mean scores by the subjects were much higher than those of the controls and in each group the males scored slightly higher than their female counterparts. On assessment with PAS, the subjects had much higher mean score of 28.94 +/- 12.61 and the controls: 18.92 +/- 7.1 with "t" of 6.19*; and the difference was statistically significant at p < 0.05 and critical "t" of 1.66. On SCL; subscale C, the mean scores for the subjects and controls were: 7.89 +/- 7.69 and 5.02 +/- 5.23 respectively and the difference was statistically significant with "t" of 2.75*. For subscale D, the mean score by the subjects was 11.09 +/- 10.56, and the controls had 4.84 +/- 6.08; and statistically significant difference with "t" of 4.59*. On subscale J, the subjects' mean score was 4.68 +/- 5.44, the controls: 1.98 +/- 3.19 with statistically significant "t" of 3.83*. CONCLUSIONS: The results showed that subjects with dermatological disorders suffered from significant emotional pain when compared to the healthy controls; the males had higher mean scores on PAS and SCL subscales, hence more likely to suffer emotional pain than their female counterparts. Finally, the need to have consultation-liaison psychiatry in the dermatology facilities in Nigeria was emphasized.

Do nerve growth factor-related mechanisms contribute to loss of cutaneous nociception in leprosy?

While sensory loss in leprosy skin is the consequence of invasion by M. leprae of Schwann cells related to unmyelinated fibres, early loss of cutaneous pain sensation, even in the presence of nerve fibres and inflammation, is a hallmark of leprosy, and requires explanation. In normal skin, nerve growth factor (NGF) is produced by basal keratinocytes, and acts via its high affinity receptor (trk A) on nociceptor nerve fibres to increase their sensitivity, particularly in inflammation. We have therefore studied NGF- and trk A-like immunoreactivity in affected skin and mirror-site clinically-unaffected skin from patients with leprosy, and compared these with non-leprosy, control skin, following quantitative sensory testing at each site. Sensory tests were within normal limits in clinically-unaffected leprosy skin, but markedly abnormal in affected skin. Sub-epidermal PGP 9.5- and trk A- positive nerve fibres were reduced only in affected leprosy skin, with fewer fibres contacting keratinocytes. However, NGF-immunoreactivity in basal keratinocytes, and intra-epidermal PGP 9.5-positive nerve fibres, were reduced in both sites compared to non-leprosy controls, as were nerve fibres positive for the sensory neurone specific sodium channel SNS/PN3, which is regulated by NGF, and may mediate inflammation-induced hypersensitivity. Keratinocyte trk A expression (which mediates an autocrine role for NGF) was increased in clinically affected and unaffected skin, suggesting a compensatory mechanism secondary to reduced NGF secretion at both sites. We conclude that decreased NGF- and SNS/PN3-immunoreactivity, and loss of intra-epidermal innervation, may be found without sensory loss on quantitative testing in clinically-unaffected skin in leprosy; this appears to be a sub-clinical change, and may explain the lack of cutaneous pain with inflammation. Sensory loss occurred with reduced sub-epidermal nerve fibres in affected skin, but these still showed trk A-staining, suggesting NGF treatment may restore pain sensation.
