Assessing the impact of childhood and adolescent chronic plaque psoriasis on parents/caregivers using the Family Dermatology Life Quality Index (FDLQI): A cross-sectional study.

Background Chronic childhood diseases are a burden for paediatric patients and their caregivers. Limited data are available on the effect of paediatric psoriasis on the caregiver's well-being and quality of life. Objective To assess the impact of childhood and adolescent chronic plaque psoriasis on parents/caregivers quality of life. Methods A single-centre cross-sectional study was performed which included 102 children with psoriasis and their caregivers. Clinico-demographic data of children and socio-demographic details of primary caregivers were collected. Out of pocket expenditure for treatment was calculated for all the patients. The quality of life of children was assessed using the Children's Dermatology Life Quality Index (CDLQI) and the caregiver's quality of life was assessed using the Family Dermatology Life Quality Index (FDLQI). Results CDLQI was impaired in 85.29 % of children with a median score of 7. The item 'symptoms' was most commonly affected (87.2%), followed by 'self-conscious' (70.5%) and 'treatment' (65.6%). FDLQI was impaired in 96.1% of caregivers with a median value of 11. The most affected FDLQI items were 'emotional' in 95%, followed by 'time-spent' in 78.4%. Almost 40% of patients had catastrophic health expenditure (CHE) and their FDLQI was significantly higher (p-0.014) compared to caregivers who did not experience catastrophic health expenditure. FDLQI had a positive relationship with the involvement of exposed body sites (p-0.003), CDLQI (p-0.000), treatment expense (p-0.031) and a negative correlation with duration of illness (p-0.04). Conclusion Childhood psoriasis has a negative impact on the quality of life of the children and caregivers highlighting the need for intervention strategies for both.

Cutaneous-immuno-neuro-endocrine (CINE) system: A complex enterprise transforming skin into a super organ.

Skin is now emerging as a complex realm of three chief systems viz. immune system, nervous system, and endocrine system. The cells involved in their intricate crosstalk, namely native skin cells, intra-cutaneous immune cells and cutaneous sensory neurons have diverse origin and distinct functions. However, recent studies have explored their role beyond their pre-defined functional boundaries, such that the cells shun their traditional functions and adopt unconventional roles. For example, the native skin cells, apart from providing for basic structural framework of skin, also perform special immune functions and participate in extensive neuro-endocrine circuitry, which were traditionally designated as functions of cutaneous resident immune cells and sensory neurons respectively. At the cellular level, this unique collaboration is brought out by special molecules called neuromediators including neurotransmitters, neuropeptides, neurotrophins, neurohormones and cytokines/chemokines. While this intricate crosstalk is essential for maintaining cutaneous homeostasis, its disruption is seen in various cutaneous diseases. Recent study models have led to a paradigm shift in our understanding of pathophysiology of many such disorders. In this review, we have described in detail the interaction of immune cells with neurons and native skin cells, role of neuromediators, the endocrine aspect in skin and current understanding of cutaneous neuro-immuno-endocrine loop in one of the commonest skin diseases, psoriasis. An accurate knowledge of this unique crosstalk can prove crucial in understanding the pathophysiology of different skin diseases and allow for generation of targeted therapeutic modalities.

Transmission patterns of C1-INH deficiency hereditary angioedema favors a wild-type male offspring: Our experience at Chandigarh, India.

BACKGROUND: Deficiency of C1-inhibitor (C1-INH) protein, caused by pathogenic variants in the Serpin family G member 1 (SERPING1) gene, is the commonest pathophysiological abnormality (in ∼95 % cases) in patients with hereditary angioedema (HAE). C1-INH protein provides negative control over kallikrein-kinin system (KKS). Although the inheritance of the HAE-C1-INH is autosomal dominant, female predominance has often been observed in patients with HAE. OBJECTIVE: To analyze the risk of transmission of SERPING1 gene variant from father or mother to their offspring. METHODS: Pedigree charts of 42 families with a confirmed diagnosis of HAE-C1-INH and a pathogenic variant in the SERPING1 gene were analysed. Patients with HAE who had had at least one child were included for analyses to assess the risk of transmission from the father or mother to their offspring. RESULTS: Overall, 49 % (189/385) of all offspring inherited the genetic defect. In the subgroup analyses, 54.8 % (90/164) female offspring and 44.8 % (99/221; p < 0.02) male offspring inherited the genetic defect. Inheritance of the genetic defect was significantly lower in male offspring. Fathers with SERPING1 gene variant had a statistically significant skewed transmission of the wild type to the male offspring as compared to the variant (57.8 % wild type vs. 42.1 % variant; p < 0.02), whereas no statistically significant difference was found when a father transmitted the variant to a female offspring. Mothers with SERPING1 gene variant had no statistically significant difference in variant transmission to male or female offsprings. CONCLUSION: Results of the study suggest that the transmission pattern of SERPING1 gene variant favours the transmission of wild-type alleles in males, especially when the father is the carrier; hence, overall, fewer males and more female offspring inherited the variant. This could be because of a selection of wild-type male sperms during spermatogenesis, as the KLK system has been reported to play a crucial role in the regulation of spermatogenesis. Although, a similar pattern was observed in the maternal transmission of the SERPING1 gene variant; the difference was not statistically significant, likely because of a small sample size.

Oral Acitretin Plus Topical Triamcinolone vs Topical Triamcinolone Monotherapy in Patients With Symptomatic Oral Lichen Planus: A Randomized Clinical Trial.

Importance: Symptomatic oral lichen planus (OLP) can be challenging to treat. Objective: To compare the efficacy of oral acitretin plus topical triamcinolone acetonide (TAC), 0.1%, with TAC monotherapy in patients with symptomatic OLP. Design, Setting, and Participants: This monocentric, investigator-initiated, placebo-controlled, investigator- and patient-blinded randomized clinical trial was conducted from December 2018 to June 2020 at the Postgraduate Institute of Medical Education and Research, a tertiary referral center in Chandigarh, India. Sixty-four patients 18 years or older with symptomatic OLP were recruited by consecutive sampling. Data were analyzed from July to December 2020. Intervention: The patients were randomized to receive either a combination of oral acitretin (25-35 mg/d) and TAC (treatment group) or TAC in combination with placebo (placebo group) for 28 weeks, with an additional 8 weeks of treatment-free follow-up after the end of treatment (36 weeks of total study duration). Main Outcomes and Measures: The disease severity and treatment response were assessed using Oral Disease Severity Score (ODSS), Oral Health Impact Profile 14 (OHIP-14), and visual analog scale (VAS). The primary aim was to assess the number of patients achieving ODSS-75 (75% reduction in ODSS compared with baseline) in both groups at 28 weeks and at the end of 36 weeks. Results: Among 64 patients, 31 in the treatment group and 30 in the placebo group completed the study (mean [SD] age, 50.6 [15.2] years vs 49.2 [14.4] years; male-female ratio, 13:19 vs 16:16). Baseline ODSS, visual analog scale, and Oral Health Impact Profile 14 scores were comparable in both groups. In the intention-to-treat analysis, there was a statistically significant higher number of patients achieving 75% or higher reduction in ODSS in the treatment group compared with the placebo group at the end of 28 weeks (28 [88%] vs 15 [47%], a 41 [95% CI, 20-61] percentage point difference between groups; P < .001; Cramér V = 0.47) and 36 weeks (27 [84%] vs 13 [41%], a 43 [95% CI, 23-67] percentage point difference between groups; P < .001; Cramér V = 0.47). Relapses during the posttreatment follow-up of 8 weeks were low among patients in both treatment and placebo groups (1 [3%] vs 2 [6%], a 3 [95% CI, -13 to 7] percentage point difference between groups; P > .99; Cramér V = 0.07). Conclusion and Relevance: In this randomized clinical trial, the combination of oral acitretin and TAC was more effective than TAC monotherapy in patients with symptomatic OLP.

Reverse Koebner phenomenon in erythema nodosum leprosum.

BACKGROUND: Erythema nodosum leprosum (ENL) is an immunologically mediated phenomenon complicating the course of leprosy. Reverse Koebner phenomenon is the term used to describe the sparing of previously injured or diseased skin by new skin lesions of the disease. METHODS: A middle-aged woman with a known case of lepromatous leprosy for the past year presented with an eruption of reddish painful nodules over her body. The lesions were found to characteristically spare the sites of previous scars. RESULTS: This sparing phenomenon of previous scar sites has been termed reverse Koebner phenomenon, a site of the body that offers greater resistance than the rest of the body to the onset of the disease, seen in various diseases, but it has never been described in ENL. CONCLUSION: This sparing of scar sites in ENL can be attributed to reverse Koebner phenomenon.

Delays in diagnosis is the commonest proximate reason for mortality in hereditary angioedema: our experience at Chandigarh, India.

BACKGROUND: Hereditary angioedema (HAE) is a rare autosomal dominant disorder characterized clinically by recurrent episodes of non-pruritic subcutaneous and/or submucosal edema. Laryngeal edema is the commonest cause of mortality in patients with HAE. Prior to the availability of first-line treatment options for management of HAE, the mortality used to be as high as 30%. The mortality has significantly reduced in countries where first-line treatment options are available and patients can access these therapies. There is paucity of literature on the outcomes of patients with HAE in developing countries where availability and access to first-line treatment options is still a challenge. OBJECTIVE: To report our experience with mortality in patients with HAE and to report factors associated with death of these patients. METHODS: We carried out a record review of all patients diagnosed to have HAE between January 1996 and August 2022. Families with HAE who had reported death of at least one family member/relative because of laryngeal edema were studied in detail. RESULTS: Of the sixty-five families (one hundred and seventy patients) registered in the clinic, sixteen families reported death of at least one family member/relative because of laryngeal edema (total thirty-six deaths). Of these sixteen families, fourteen families reported that one or more family members had experienced at least one attack of laryngeal edema. One patient died during follow-up when she was taking long-term prophylaxis with stanozolol and tranexamic acid while remaining thirty-five patients were not diagnosed to have HAE at the time of their death. At the time of death of all thirty-six patients, at least one other family member had symptoms suggestive of HAE but the diagnosis was not established for the family. CONCLUSIONS: This is the largest single centre cohort of patients with HAE in India reporting mortality data and factors associated with death in these families. Delay in diagnosis is the commonest reason for mortality.

Genomic characterization of Mycobacterium lepromatosis from ENL patients from India.

BACKGROUND: Leprosy is caused by Mycobacterium leprae and Mycobacterium lepromatosis. Both organisms cannot be cultured in vitro. M. lepromatosis was found to be associated mainly with diffuse lepromatous leprosy and with Lucio's phenomena initially. Later, M. lepromatosis was observed in borderline leprosy cases (BL), lepromatous leprosy cases (LL) and leprosy reactional cases (T1R and ENL). Although many cases are being reported with similar clinical features like Lucio phenomenon in India but M. lepromatosis was not isolated from these cases. The aim of this study was to screen MB patients and patients with type 2 reaction for the presence of M. lepromatosis. METHODOLOGY: We recruited a total of 75 multibacillary leprosy cases (45 MB cases without reaction and 30 type 2 reaction (ENL) cases) from TLM hospitals Purulia (West Bengal), Barabanki (Uttar Pradesh), Shahdara (Delhi) and PGIMER (Chandigarh), India. Punch biopsies of 5 mm were collected in 70% ethanol from all the study subjects. DNA was extracted followed by Hemi-nested PCR targeting 16S rRNA gene specific for M. lepromatosis. Further, PCR products were processed for Sanger sequencing for an absolute confirmation of M. lepromatosis. Whole genome sequencing was done to confirm the presence of M. lepromatosis. RESULT: We observed presence of M. lepromatosis in 4 necrotic ENL patients by heminested PCR. There was 100% 16S rRNA sequence similarity with M. lepromatosis FJ924 in one case, 98.96% in two cases and in one case it was 90.9% similarity by nucleotide BLAST (BLASTn) by using the NCBI website. On the basis of Sanger sequencing, we noted presence of M. lepromatosis in 3 necrotic ENL patients as one sample only gave 90.9% similarity by BLASTn. On the basis of de novo assembly and genome obtained, only one sample S4 with a 2.9 mb genome size was qualified for downstream analysis. Sixteen M. lepromatosis- specific proteins were identified in this case and the closest species was M. lepromatosis strain FJ924 based on whole genome level phylogeny. CONCLUSION: These results provide valuable insights into the prevalence of M. lepromatosis in ENL patients in different regions of India and contribute to our understanding of the genetic characteristics of this pathogen in the context of leprosy.

Mycobacterium Indicus Pranii (MIP) Vaccine: Pharmacology, Indication, Dosing Schedules, Administration, and Side Effects in Clinical Practice.

Mycobacterium indicus pranii (MIP), previously called Mw vaccine, is a one-of-a-kind immunomodulatory vaccine. It was indigenously developed in India for use in leprosy. MIP is heat-killed Mycobacterium w, which is a non-pathogenic atypical mycobacterium belonging to Class IV of Runyon classification. It shares epitopes with Mycobacterium leprae and Mycobacterium tuberculosis, which forms the rationale behind its use in leprosy and tuberculosis. MIP activates both innate and acquired immunity. It induces a Th1 and Th17 immune response along with downregulation of Th2 pathway and activates macrophages and dendritic cells. MIP vaccine is safe with adverse effects such as local site erythema, swelling, and rarely fever and other systemic reactions. Apart from leprosy, MIP has been used in dermatological diseases such as warts and psoriasis. Clinical trials have evaluated the efficacy of MIP in a plenitude of non-dermatological conditions such as category II tuberculosis, Gram-negative sepsis, non-small cell lung cancer, human immunodeficiency virus (HIV), muscle-invasive bladder cancer, and very recently, coronavirus 2019 (COVID-19). In vitro and animal studies have also demonstrated its utility in leishmaniasis, melanoma, and as a vaccine for the prevention of pregnancy. The PubMed database was searched using "Mycobacterium indicus pranii, MIP, Mycobacterium w" as the keyword in title. This comprehensive review provides useful information for healthcare professionals about immunotherapeutic potential of MIP vaccine, its composition, dosing schedule, administration, and side effects besides its efficacy in various indications other than leprosy.

Assessment of Clinical, Histopathological, and Bacteriological Findings in Treated Leprosy Patients with Persistent Skin Lesions: A Retrospective Cohort Study.

Since the introduction of multidrug therapy (MDT), various disabilities/morbidities due to leprosy have been prevented. However, there is a subset of patients in whom the skin lesions do not resolve completely or remain unchanged despite a full course of MDT, which is a great source of anxiety to the patient and their family members. Hence, we tried to ascertain the putative causes and risk factors of persistent skin lesions (PSLs) by analyzing the clinical, histopathological, bacteriological, and drug resistance patterns. This is a retrospective, cohort study wherein 35 patients who had PSLs after completion of MDT were included. The majority of the patients were 18 to 30 years of age, with males predominating. Borderline tuberculoid leprosy was the most common clinical spectrum observed (71.4%). The majority had PSLs distributed predominantly over photo-exposed sites (upper limbs > trunk > face). Eight patients (22.8%) had a history of contact with leprosy patients in their family, and six patients (17.1%) had associated comorbidities. Improvement in histopathological parameters such as a decrease in granuloma fraction was observed in 22 patients (62.8%) with PSLs after release from treatment in comparison with baseline. Four patients (11.4%) were noted to have drug resistance (three to rifampicin and one to dapsone). Thus, our study emphasizes that leprosy patients with PSLs after completion of MDT should undergo histopathological evaluation and drug resistance studies.

High frequency of ofloxacin resistance patterns of Mycobacterium leprae from India: An indication to revisit second line anti-leprosy treatment regimen.

OBJECTIVES: Drug resistance in leprosy is an emerging concern, leading to treatment failures, recurrences, and potential spread of resistant Mycobacterium leprae in the community. In this study, we aimed to assess drug resistance prevalence and patterns amongst leprosy patients at a tertiary care referral hospital in India. METHODS: Mutations in drug resistance determining regions for dapsone, rifampicin, and ofloxacin of the M. leprae genome in DNA extracted from skin biopsies of 136 leprosy patients (treatment-naive = 67, with persistent skin lesions = 35, with recurrence = 34) were analysed by polymerase chain reaction followed by Sanger sequencing. Wild-type strain (Thai-53) was used as a reference strain. RESULTS: Resistance mutations were identified in a total of 23 patients, constituting 16.9% of the cohort. Within this subset of 23 cases, resistance to ofloxacin was observed in 17 individuals (12.5%), while resistance to both dapsone and rifampicin was detected in three patients each (2.2% for both). The occurrence of ofloxacin resistance showed minimal disparity between recurrent and treatment-naive cases, at 17.6% and 16.4%, respectively. Dapsone resistance emerged in two treatment-naive cases and one case with persistent skin lesions. Notably, none of the treatment-naive cases or those with recurrence/relapse exhibited rifampicin resistance. Subsequently, no statistically significant correlation was identified between other clinical variables and the presence of antimicrobial resistance. CONCLUSIONS: The occurrence of resistance to the current multidrug therapy regimen (specifically dapsone and rifampicin) and to ofloxacin, a secondary antileprosy medication in M. leprae, represents a concerning scenario. This calls for an expansion towards bactericidal drug options and the establishment of robust surveillance for drug resistance in countries burdened with high leprosy rates. Moreover, the introduction of stringent antimicrobial stewardship initiatives is imperative. As a single centre study, it represents a limited, cross-sectional view of the real situation in the field.
