Assessment of cutaneous disease activity in early lupus and its correlation with quality of life: a cross-sectional study.

Systemic lupus erythematosus (SLE) is a multi-system autoimmune disease with varied dermatological manifestations that are almost universal. Overall, lupus disease has a major effect on the quality of life in these patients. We assessed the extent of cutaneous disease in early lupus and correlated it with the SLE quality-of-life (SLEQoL) index and disease activity measures. Patients diagnosed as SLE with the skin involved were recruited at the first presentation and were assessed for cutaneous and systemic disease activity using the cutaneous lupus erythematosus disease area and severity index (CLASI) and the Mexican-SLE disease activity index (Mex-SLEDAI), respectively. Quality of life was assessed with the SLEQoL tool while systemic damage was captured by the SLICC damage index. Fifty-two patients with SLE who had cutaneous involvement were enrolled (40, 76.9% females) with a median disease duration of 1 month (1-3.7). The median age was 27.5 years (IQR: 20-41). Median Mex-SLEDAI and SLICC damage index were 8(IQR: 4.5-11) and 0 (0-1), respectively. The median CLASI activity and damage scores were 3 (1-5) and 1 (0-1), respectively. Overall, there was no correlation between SLEQoL with CLASI or CLASI damage. Only the self-image domain of SLEQoL correlated with total CLASI (ρ = 0.32; p = 0.01) and CLASI-D (ρ = 0.35; p = 0.02). There was a weak correlation of CLASI with the Mexican-SLEDAI score (ρ = 0.30; p = 0.03) but not with the SLICC damage index. In this cohort of early lupus, cutaneous disease activity in lupus had a weak correlation with systemic disease. Cutaneous features did not appear to influence the quality of life except in the self-image domain.

Prevention of transmission of leprosy: The current scenario.

With the worldwide implementation of WHO multidrug therapy in the 1980s, the global burden of leprosy has decreased. However, the annual new case detection rate around the world has remained nearly static over the past decade with India, Brazil, and Indonesia contributing the majority of these new cases. This has been attributed to the ongoing transmission of Mycobacterium leprae from existing untreated cases and partly to the intensive new case detection programs operative in endemic areas. The WHO has called for a "global interruption of transmission of leprosy by 2020". Targeted chemoprophylaxis of contacts may help bring down the number of new cases. The single-dose rifampicin currently in use for post-exposure prophylaxis (PEP) has limitations and so newer antileprosy drugs and regimens have been trialed for chemoprophylaxis. BCG re-vaccination in combination with chemoprophylaxis for the prevention of leprosy transmission has not been very encouraging. The use of the anti-phenolic glycolipid-1 (PGL-1) antibody test to detect subclinical cases and administer targeted chemoprophylaxis was unsuccessful owing to its low sensitivity and technical difficulties in a field setup. There is a pressing need for newer multidrug chemoprophylactic regimens using second-line antileprosy drugs. The Netherlands Leprosy Relief has proposed an enhanced PEP++ regimen. A simple but highly sensitive and specific serological test to detect subclinical cases at the field level needs to be developed. Although there are a number of challenges in the large-scale implementation of strategies to halt leprosy transmission, it is important to overcome these in order to move towards a "leprosy-free world."

Exploring quinolone resistance-determining region in Neisseria gonorrhoeae isolates from across India.

BACKGROUND & OBJECTIVES: Antimicrobial resistance in Neisseria gonorrhoeae, the causative agent of gonorrhoea, is a subject of worldwide attention. The present study was undertaken to examine the rates of ciprofloxacin resistance, to correlate mutations in gyrA and parC genes with the level of resistance and to look for a variation in mutation pattern, if any, in isolates from across the country. METHODS: A total of 113 isolates of N. gonorrhoeae collected from sexually transmitted infection patients in six centres during November 2010 to October 2013 were investigated. Minimum inhibitory concentration (MIC) determination was done by E-test and results interpreted as per Calibrated Dichotomous Sensitivity criteria. DNA sequence analysis of gyrA and parC genes was done. RESULTS: Of the 113 isolates, only three (2.6%) were susceptible whereas eight (7.07%) were less susceptible, 32 [28.3%, 95% confidence interval (CI): 20.4-37.6%] resistant (MIC 1-3 µg/ml) and 70 (61.9%, 95% CI: 52.2-70.7%) exhibited high-level resistance (HLR) (MIC ≥4 µg/ml) to ciprofloxacin. A S91F substitution in gyrA gene was demonstrated in all ciprofloxacin non-susceptible isolates. All resistant and HLR isolates had a double mutation in gyrA gene. However, only 5.7 per cent of HLR isolates showed double mutations in parC gene. One isolate (MIC 32 µg/ml) had a previously undescribed G85D substitution in the parC gene. INTERPRETATION & CONCLUSIONS: A S91F substitution in gyrA gene was seen in all non-susceptible isolates of N. gonorrhoeae. It may be used as a marker for ciprofloxacin resistance for molecular surveillance approaches to complement the culture-based methods.

Functional characterization of CD4 and CD8 T cell responses among human papillomavirus infected patients with ano-genital warts.

Ano-genital warts are considered one of the commonest and highly infectious sexually transmitted infections. These warts are primarily caused by the human papillomavirus (HPV) of the family Papillomaviridae, genus alpha-papillomavirus, species 10 and types 6 and 11. However the high recurrence rate of warts is a matter of serious concern to the patients and a challenge for the treating physician. The conventional treatment options are targeted only to the local site of warts. There is no systemic treatment modality as there is limited understanding of the disease immune-pathogenesis. The role of cell-mediated immunity in combating HPV infection is not clearly defined. Hence the present study is aimed at investigating the CD4+ T helper (Th1 and Th2) and CD8+ T cell responses among wart patients. In this study, we compared HPV6 and HPV11 antigen-specific T cell responses among venereal wart patients relative to healthy controls. Significant decrease in percent frequencies of IFN-γ producing CD4+ and CD8+ T cells were observed in HPV infected wart patients. On the other hand, the frequency of CD4+ T cells expressing IL-4 was significantly increased in these patients as compared to healthy controls. The observed functional skewing of HPV specific T cells from Th1 to Th2 response in patients indicated suppressed immunity against the HPV. Moreover, decrease in CD8 T cell function correlated with poor wart clearance. Our findings open future avenues for exploring potential immunomodulation strategies as an adjunct to standard treatment for better management of these patients and prevention of recurrence.

Distinct clinico-immunological profile of patients infected with human papilloma virus genotypes 6 and 11.

Anogenital warts are primarily caused by Human Papillomavirus (HPV) type 6 and 11, which belong to the taxonomic family Papillomaviridae, genus alpha-papillomavirus and species 10. The presentation of the warts is varied and most of the patients have high recurrence rate of wart lesions. Studies had shown that an effective cellular immune response is required for the control of HPV infection. Here, we report distinct clinico-immunological profile of two patients presenting with venereal warts caused by HPV genotypes 6 and 11. The Case 1 manifested greater number of verrucous warts and case 2 had fewer subtle lesions. Further, evaluation of HPV antigen-specific cellular immune response revealed a robust T cell response against HPV6 peptide and a weak response against HPV11 in case 1. Interestingly, HPV genotyping revealed type 6 in case 1 with greater severity of infection and robust immune response against HPV6 peptide. In contrast, case 2 presented with milder infection and weak immune response and was positive for genotype 11. More extensive study with larger cohorts will strengthen our observation and could be relevant for designing immunotherapeutic adjunct strategies along with the standard treatment for rapid clearance of HPV infections in these patients. This communication reports immune status of two patients with venereal warts and their correlation with clinical presentation and the genotyping.

Antimicrobial Resistance and Neisseria gonorrhoeae Multiantigen Sequence Typing Profile of Neisseria gonorrhoeae in New Delhi, India.

Molecular epidemiology of 100 consecutive gonococcal isolates collected between April 2010 and October 2013 from New Delhi was investigated using Neisseria gonorrhoeae multiantigen sequence typing (NG-MAST) along with its association with antimicrobial resistance profiles. Neisseria gonorrhoeae isolates were assigned into 60 different sequence types and 43 (71.6%) were novel. Sole representation was seen in 76.6% sequence types. There was significant association between ST6058 and resistance to penicillin (P = 0.00) and tetracycline (P = 0.002).

Topical Corticosteroid Misuse: The Scenario in Patients Attending a Tertiary Care Hospital in New Delhi.

INTRODUCTION: Irrational use of Topical Corticosteroid (TC) is quite common in India due to unrestricted availability and use of TC not only by general public but also by physicians and chemists due to quick relief of symptoms in different dermatological conditions. AIM: The present study was conducted to evaluate and analyse the prevalence of misuse of TC and the causes behind misuse of TC among patients in a dermatology outpatient department in New Delhi. MATERIALS AND METHODS: This was a cross-sectional observational questionnaire based study conducted over a period of 5 months (1st June 2015 to 30th November 2015). Patients were questioned and assessed for misuse of TCs in terms of indication, dose, frequency, duration and source of recommendation of TC. RESULTS: During the study period, 256 (11.77%) patients presented with inappropriate use of TC out of 2174 patients attending OPD of dermatology unit of a government hospital. A total of 250 patients presented with adverse effects of TC resulting from the misuse of these drugs. There were 60%female patients and 20-29 years (38%) was the most common age group affected. We found fungal infection (38%) was the most common reason of abuse followed by facial acne (29%) and lightening of skin colour (8.4%). Friends and family (33.2%) were found to be the most influencing factors for misuse of TC. Betamethasone (72.8%) was the most commonly used TC preparation and tinea incognito (26.4%) followed by facial acne (25.6%) were the most common side effect experienced. CONCLUSION: Outcome of the misuse of TC could be dreadful and the cause for same lies at all levels- patients, family, physicians and the regulatory authorities.

Linear adamantinoid basal cell carcinoma in the axilla.

We present a case of asymptomatic deeply pigmented linear plaque with rolled borders that we encountered in an elderly Indian male over a sun protected site, the left axilla. The diagnosis of linear adamantinoid basal cell carcinoma was confirmed on histopathological examination.

Treatment of leprosy.

Leprosy is a curable disease, having been eliminated from many countries, including India. This has been possible due to the wide availability of effective and safe drugs. Treatment of leprosy has undergone considerable changes over decades, from chaulmoogra oil in 1915 to dapsone monotherapy in 1946, then eventually to multidrug therapy (MDT) in 1982. In the last two decades, reports of resistance to all first-line drugs have appeared in the literature, with the need to conduct clinical trials using newer but highly bactericidal drugs and their combinations against Mycobacterium leprae.

Correlation of Vitamin D Levels with Pigmentation in Vitiligo Patients Treated with NBUVB Therapy.

Cholecalciferol (vitamin D) might play a physiological role in photo-induced melanogenesis in human skin. We estimated the levels of 25-hydroxy vitamin D [25(OH)D] before, during, and after Narrow Band Ultraviolet B (NBUVB) radiation in patients of vitiligo and their correlation with NBUVB induced pigmentation. Thirty patients of vitiligo and equal number of age and sex matched controls were recruited for the study. Vitiligo patients were treated with NBUVB thrice weekly for 12 weeks. [25(OH)D] levels and Vitiligo Area and Severity Index (VASI) were calculated at 0 (baseline), 6, and 12 weeks. Baseline [25(OH)D] levels were measured in controls. Significant reduction in VASI score was observed after 12 weeks of therapy. Comparison and correlation between mean improvement in VASI and [25(OH)D] levels at 12 weeks showed moderate correlation, and the results were statistically insignificant. Mean reduction in VASI and increase in [25(OH)D] levels after 12 weeks of NBUVB showed moderate correlation. Thus, vitamin D might play a significant role in photo-induced melanogenesis. However, there might be additional effects of the phototherapy on melanogenesis. The complete mechanism of NBUVB induced pigmentation in vitiligo needs to be elucidated.

Nucleic acid amplification tests (NAATs) for gonorrhoea diagnosis in women: experience of a tertiary care hospital in north India.

BACKGROUND & OBJECTIVES: Gonorrhoea is among the most frequent of the estimated bacterial sexually transmitted infections (STIs) and has significant health implications in women. The use of nucleic acid amplification tests (NAATs) has been shown to provide enhanced diagnosis of gonorrhoea in female patients. However, it is recommended that an on-going assessment of the test assays should be performed to check for any probable sequence variation occurring in the targeted region. In this study, an in-house PCR targeting opa-gene of Neisseria gonorrhoeae was used in conjunction with 16S ribosomal PCR to determine the presence of gonorrhoea in female patients attending the tertiary care hospitals. METHODS: Endocervical samples collected from 250 female patients with complaints of vaginal or cervical discharge or pain in lower abdomen were tested using opa and 16S ribosomal assay. The samples were also processed by conventional methods. RESULTS: Of the 250 female patients included in the study, only one was positive by conventional methods (microscopy and culture) whereas 17 patients were found to be positive based on PCR results. INTERPRETATION & CONCLUSIONS: The clinical sensitivity of conventional methods for the detection of N. gonorrhoeae in female patients was low. The gonococcal detection rates increased when molecular method was used giving 16 additional positives. Studies should be done to find out other gene targets that may be used in the screening assays to detect the presence of gonorrhoea.

Granuloma faciale with extrafacial involvement and response to tacrolimus.

Granuloma faciale (GF) is a chronic condition characterized by red-brown plaques with follicular accentuation present usually on the face. We present a case of 35-year-old female with 5 year history of plaques over cheek and extra facial sites consistent with GF and its response to topical tacrolimus. This case supports previous reports of successful treatment of GF with topical tacrolimus.

A comparative study on efficacy of high and low fluence Q-switched Nd:YAG laser and glycolic acid peel in melasma.

BACKGROUND: Melasma is acquired symmetric hypermelanosis characterized by light-to-deep brown pigmentation over cheeks, forehead, upper lip, and nose. Treatment of this condition is difficult and associated with high recurrence rates. With the advent of newer therapies, there is interest in the use of glycolic acid peels and Q-switched Nd:YAG laser (QSNYL) in high and low fluence for this disorder. AIMS: To compare the therapeutic efficacy of low fluence QSNYL, high fluence QSNYL, and glycolic acid peel in melasma in three study groups of 25 patients each. METHODS: Seventy-five Indian patients diagnosed as melasma were included. These patients were randomly divided in three groups (Group A = 25 patients of melasma treated with low-fluence QSNYL at weekly intervals, Group B = 25 patients of melasma treated with glycolic acid peel at 2 weeks intervals, Group C = 25 patients of melasma treated with high-fluence QSNYL at 2 weeks intervals). Study period and follow-up period was of 12 weeks each. Out of the 75 patients included, 21 patients in Group A, 19 patients in Group B, and 20 patients in Group C completed the study. Response to treatment was assessed using melasma area and severity index score. RESULTS: Significant improvement was recorded in all the three groups. The improvement was statistically highly significant in Group A as compared to Group C (P<0.005), significant in Group A as compared to Group B (P<0.05), and also in Group B when compared to Group C (P<0.05). Low-fluence QSNYL was associated with least side effects. CONCLUSIONS: This study shows the efficacy of low-fluence QSNYL and glycolic acid peel in melasma. These could be an effective treatment options compared to conventional methods for the treatment of melasma.

Revalidation of various clinical criteria for the classification of leprosy--a clinic-pathological study.

UNLABELLED: WHO guidelines classify leprosy patients clinically into PB and MB group based on the number of skin lesions (NSL) with > or = 6 skin lesions as a criterion for MB leprosy. Other clinical criteria for classification are based on the number of body areas affected (NBAA) and on size of the largest skin lesions (SLSL). They are also fairly simple and easily practicable in the field. OBJECTIVES: The objective of this study is to explore whether sensitivity and specificity of the WHO classification can be improved by addition of clinical criteria based on NBAA and SLSL to WHO classification. STUDY DESIGN: Among 100 newly diagnosed untreated leprosy patients classified into PB and MB group according to WHO classification, the NSL and NBAA were recorded and the size (longest diameter) of largest skin lesion was measured in centimeters. The Receiver Operator Characteristic (ROC) curves were plotted for each parameter to find the best cut off point (with highest sensitivity and specificity). RESULTS: The sensitivity and specificity of the WHO classification tested, using slit-skin smear (SSS) and skin biopsy results as the gold standard, was found to be 63% and 85% respectively. The ROC curve for NSL found the best cut off of three and more lesions for MB group (sensitivity 90% & specificity 80%). Similarly, ROC curves for NBAA and SLSL found the best cut off points for classification into MB group to be two or more (sensitivity 90% & specificity 75%) and 5 cm or more (sensitivity 87% and specificity 65%) respectively. On combining all these criteria together sensitivity was increased to 98.5% with no significant change in specificity, which was 77.5%. CONCLUSION: The study concluded that the sensitivity of the present clinical classification can be further improved by addition of two other clinical criteria.

1064 nm Q switched Nd: YAG laser treatment of nevus of Ota: an Indian open label prospective study of 50 patients.

BACKGROUND: Nevus of Ota is very common in Asians. Estimated male to female ratio is 1:4.8. Patients seek treatment early in life due to psychological trauma and cosmetic disfigurement. The creation of high power, short pulse Q switched lasers has recently provided tools for considerable therapeutic advances in the treatment of dermal pigmented lesions. AIMS: To determine the efficacy and side-effect profile of Q switched Nd:YAG Laser (QSNYL) in fifty Indian patients. METHODS: Fifty patients of nevus of Ota underwent multiple treatments (average 5 sessions) at monthly intervals carried out over a period of 2 years with QSNYL (Med-lite C6). Of the 50 patients, 2 were males; and the rest were females. Skin types treated included phototype IV and V. The response after subsequent treatments was documented through serial photographs that were taken before and after every treatment session. Response to the treatment was graded based on quartile grading scale. RESULTS: Near total improvement was seen in 8%, marked improvement in 22%, moderate improvement in 38% and 32% patients reported less than 25% clearing of the lesion. All patients reported some improvement. Transient postinflammatory hyperpigmentation was observed in 4 (8%) patients, which cleared with use of sunscreens and bleaching agents within 2 months. No textural change or scarring was observed in any patient. CONCLUSIONS: QSNYL is an easy-to-perform and effective treatment in cases of nevus of Ota in Indian patients with few side effects.

A case of angiokeratoma circumscriptum of the tongue: response with carbon dioxide and pulsed dye laser.

Solitary angiokeratoma circumscriptum (AC) of the tongue is a rare entity. We present a case of solitary AC over the ventral surface of the tongue present for 3 years. The patient was treated with a combination of carbon dioxide (CO(2)) and pulsed dye laser (PDL). There was more than 75% improvement in the lesion after treating with alternate sessions of CO(2) and PDL.

Occurrence of plant sensitivity among patients of photodermatoses: a control-matched study of 156 cases from New Delhi.

BACKGROUND: Photodermatitis is an abnormal response to ultraviolet radiation (UVR). The photoallergic contact dermatitis caused by plant allergens is a serious cause of morbidity in India. Airborne contact dermatitis is the classical presentation of plant-induced dermatosis, which may become difficult to differentiate from chronic actinic dermatitis in chronic cases. The rapid growth of parthenium weed in India and its ill effects on the population make it important to detect all cases of parthenium sensitivity, which in some cases might simulate photodermatitis. AIMS: This study aims to detect the occurrence of plant sensitivity and photosensitivity in idiopathic-acquired photodermatoses, airborne contact dermatitis and general population taken as controls. METHODS: One hundred and fifty six consecutive patients suffering from polymorphic light eruption (PMLE), chronic actinic dermatitis (CAD) and airborne contact dermatitis (ABCD) were enrolled in the study over a period of three years (June 2004 to May 2007). An equal number of age and sex matched healthy subjects were enrolled in the study as controls. All the patients were subjected to detailed history taking, clinical examination and histopathological examination for diagnosis. Patch and photopatch testing were perfomed in all the patients and healthy controls for detection of allergic and photoallergic reactions to parthenium, xanthium and chrysanthemum plant antigens and control antigens. RESULTS: Out of 156 patients enrolled in the study, 78 (50%) had CAD, 67 (42.9%) had PMLE and 11 (7.05%) had ABCD. The occurrence of parthenium/xanthium allergy and photoallergy, either to parthenium or both was most commonly found in ABCD (72.7%), followed by CAD (32%). In PMLE 4.5% cases showed photoallergy. Only 1.9% in the control group showed sensitivity to parthenium and xanthium. CONCLUSION: This study indicates that parthenium (and possibly xanthium) may act as important environmental factors in the initiation and perpetuation of not only ABCD but of CAD as well. Photoexacerbation to UVA at positive parthenium/xanthium sensitivity sites in ABCD and CAD indicates that ABCD with photosensitivity to compositae can lead to CAD.
