BACKGROUND: Hirsutism is estimated to affect 10% to 20% of females, provoking significant psychological damage and social embarrassment. Polycystic ovary syndrome is a major cause of hirsutism.

AIM: Assessing the impact of adding combined oral contraceptives (COCs) or metformin to laser hair removal on the quality of life of polycystic ovarian syndrome (PCOS) patients with hirsutism.

METHODOLOGY: One-hundred-fifty PCO patients diagnosed with hirsutism were included in this study. Patients were randomized into three groups: group 1 received laser hair removal alone, group 2 received metformin and laser hair removal, and group 3 received COCs and laser hair removal. A diode laser with a wavelength of 810 nm was used for hair removal in all patients according to a protocol of 6 monthly sessions followed by another two sessions after three and six months. Patients were assessed using a visual analog scale (VAS) and Dermatology Life Quality Index (DLQI) and a customized questionnaire (Hirsutism Life Quality Index; HLQI).

RESULTS: All patients showed a significant improvement in both quality indices (DLQI and HLQI) after treatment relative to pretreatment. Group 3 showed significantly better improvements when compared with group 2 and group 1. At three and six months, group 3 showed non-significantly better DLQI and HLQI as compared with at zero months. On the other hand, group 2 patients displayed significant worsening of both DLQI and HLQI scores at three months, with subsequent improvements again at six. Finally, group 1 patients showed nonsignificant worsening at three months, and significant worsening at 6 months.

CONCLUSION: Combining hormonal treatment with laser hair removal can achieve greater hair reduction, significant improvements in patients' QOL, and better maintenance as compared with when combining metformin with laser hair removal or conducting alone.

El-Kalioby, "Does vitamin D deficiency predispose to keloids via dysregulation of koebnerisin (S100A15)? A case-control study.", Wound repair and regeneration : official publication of the Wound Healing Society [and] the European Tissue Repair Society, 2021. Abstract

Keloids result from uncontrolled inflammation and fibrosis during wound healing. Vitamin D can regulate skin proliferation and inflammation. Fibroblasts are vitamin D-responsive target cells and are source of koebnerisin (an antimicrobial peptide released during inflammation and wound healing). This study aimed to assess the levels and correlations between the serum and tissue 25-Hydroxyvitamin D, tissue vitamin D receptors, and serum and tissue koebnerisin (S100A15) in patients with keloids. Nineteen patients with keloids and 20 matched controls were recruited. From each keloid patient, a serum sample and two biopsies were taken from the keloid (lesional) (Tissue A) and from normal skin (non-lesional) (Tissue B). From controls, a serum sample and a tissue biopsy from normal skin were taken. Serum and tissue 25-Hydroxyvitamin D, tissue vitamin D receptors, and serum and tissue koebnerisin were measured in retrieved samples using ELISA. Results revealed a significantly lower serum 25-Hydroxyvitamin D, tissue vitamin D receptors, as well as, serum and tissue koebnerisin in keloid patients compared to controls. Tissue 25-Hydroxyvitamin D was significantly lower in keloidal skin biopsy (Tissue A) compared to non-lesional normal skin biopsy (Tissue B). Tissue koebnerisin showed a significant positive correlation with tissue vitamin D receptors, and a significant negative correlation with tissue 25-Hydroxyvitamin D. There was a significant negative correlation between serum 25-Hydroxyvitamin D and duration of keloid. Accordingly, low serum and tissue 25-Hydroxyvitamin D and deficient tissue vitamin D receptors contribute to the pathogenesis of keloids. This can be partly mediated by dysregulation of the antimicrobial peptide; koebnerisin. Artificial antimicrobial peptides and koebnerisin-modifying drugs, for example, vitamin D and TNF-α inhibitors can have a role in keloid prevention and treatment.

El-Kalioby, M., M. H. M. El-Komy, E. R. Said, M. A. Amer, D. G. Saadi, F. N. Mohammed, L. A. Rashed, E. D. ElDesouky, and A. M. AlOrbani, "Downregulation of interleukin 36γ and its cleaver cathepsin G following treatment with narrow-band ultraviolet B phototherapy in psoriasis vulgaris.", The Journal of dermatological treatment, pp. 1-19, 2021. Abstract

BACKGROUND: Growing evidence suggests the important role of IL-36 in the pathogenesis of psoriasis. Cathepsin G is a neutrophil-derived protease that can activate IL-36γ.

OBJECTIVE: To assess the expression of IL-36γ and cathepsin G in psoriasis and to quantify the impact of treatment with narrow-band ultraviolet B phototherapy (NB-UVB) on their levels.

METHODS: This case-control study involved 26 patients with moderate-severe psoriasis and 25 healthy volunteers. Psoriasis patients eligible for phototherapy received 24 NB-UVB sessions. Punch skin biopsies were obtained from all participants at recruitment and after phototherapy from patients. Real-time PCR was utilized for quantitative assessment of IL-36γ and cathepsin G expression in tissue samples.

RESULTS: The expression of IL-36γ and cathepsin G was significantly higher in psoriasis before NB-UVB therapy compared to controls (p < 0.001). Both proteins decreased significantly with clinical improvement following NB-UVB therapy compared to baseline (p < 0.001). However, their expression after treatment was still higher than controls (p < 0.001).

CONCLUSION: IL-36γ and cathepsin G expression is upregulated in psoriatic lesions, supporting their role as mediators of inflammation in psoriasis. Downregulation of IL-36γ and cathepsin G is a possible mechanism for psoriasis improvement after NB-UVB therapy. IL-36 and cathepsin G can be considered as therapeutic targets for psoriasis.

El-Komy, M. H. M., A. Abdelnaby, and M. El-Kalioby, "How does COVID-19 impact psoriasis practice, prescription patterns, and healthcare delivery for psoriasis patients? A cross-sectional survey study.", Journal of cosmetic dermatology, 2021. Abstract

BACKGROUND: Psoriasis is a chronic skin disease that needs continuous medical care. During COVID-19, delivering medical service was negatively affected.

AIMS: To describe the impact of COVID-19 on psoriasis healthcare delivery, management, and practice.

METHODS: This observational cross-sectional study was conducted on 197 dermatologists using a validated online questionnaire. The survey evaluated the effect of COVID-19 on the decisions, prescription patterns, appointments rescheduling, and healthcare delivery for psoriasis patients by dermatologists. The questionnaire was developed and validated with a reliability score >0.7.

RESULTS: During the pandemic, most dermatologists delayed initiating biological/immunosuppressive therapy for psoriasis unless urgently needed by the patient. For patients already receiving biologics or immunosuppressive treatment, most dermatologists favored continuation of therapy. Almost half (44.2%) of participants do not perform SARS-CoV-2 PCR screening before initiating biologics/immunosuppressive therapy. Dermatologists also reported an increased prescription of topical medications (79.2%), natural sunlight (28.4%), acitretin (26.9%), and home UVB (21.3%). Opinions regarding the use of hydroxychloroquine for COVID-19 treatment/prophylaxis for psoriasis patients were controversial. Intervals between face-to-face follow-up visits were prolonged by 71.6% of dermatologists. More than half of participants reported that their patients discontinued treatment without medical consultation. More than three fourth of responders either agreed or strongly agreed that COVID-19 negatively affected psoriasis patients.

CONCLUSIONS: The COVID-19 pandemic has a negative impact on psoriasis management and healthcare delivery. Dermatologists are cautious about using biologics and immunosuppressive drugs during the pandemic, making case-by-case decisions. Psoriasis patients need compliance monitoring, and psychological support during the pandemic, which can be facilitated by teledermatology.

Abstract

Pemphigus vulgaris (PV) is a life-threatening, autoimmune blistering disease affecting the skin and mucous membranes, exerting a detrimental effect on the quality of life (QOL). Our aim was to evaluate the psychological status and QOL of patients with PV and investigate Interleukin-6 (IL-6) as a possible contributor to the pathogenesis of pemphigus and associated depression. The study included 22 patients with PV, 21 patients with depression, and 20 normal controls. All the 63 participants were subjected to assessment of their QOL, psychiatric profile, as well as estimation of serum level of IL-6. All (100%) of the included patients with PV had a negative effect on their QOL, which was significant compared with controls (P<0.001). Among patients with PV, 13 patients (59.1%) had depression. IL-6 was non-significantly elevated in the pemphigus group when compared with the controls (P=0.057). QOL was significantly worse in the depressed pemphigus subgroup compared with the non-depressed pemphigus subgroup (P=0.006 and <0.001) respectively. However, IL-6 was non-significantly elevated in the depressed pemphigus subgroup compared with the non-depressed pemphigus subgroup (P=0.095). A marked deterioration in the QOL was observed in patients with pemphigus. More than 50%, but not all, of patients with pemphigus had depression. IL-6 was non-significantly elevated in patients with pemphigus.

Abstract

Oral erosions and ulcers of pemphigus vulgaris (PV) are a debilitating condition that is usually difficult to treat. The wound healing properties of platelet-rich plasma (PRP) encouraged us to evaluate its usefulness in treatment of non-healing oral PV lesions. Seven patients with chronic oral PV, resistant to conventional therapy, were treated with weekly to monthly injections of PRP of affected mucosal membranes. All recruits reported improvement in pain and mastication and 6 of 7 patients had an improvement in pemphigus disease area index scores with PRP treatment. PRP injections seems to accelerate the healing process and decrease the pain and eating discomfort associated with the oral erosions and ulcers induced by PV.
