RÉSUMÉ

Introduction Telogen effluvium (TE) is a common sequela of SARS-CoV-2 infection. Existing studies are highly heterogeneous. We aimed to assess the prevalence of TE in a cohort of patients with severe disease hospitalized for acute COVID-19. Methods This prospective cohort study was conducted at the University Clinic of Dermatology, part of the COVID-19 University Hospital Network throughout the pandemic. The acute phase data were extracted from electronic hospital records. Details about hair loss were obtained at two follow-up points, 3 and 6 months after hospital discharge, using telephone interviews. Results A total of 77 patients were successfully followed up, and 40 (48.8%) were male. The mean age was 55.91, SD=10,588. Overall, 68.8% of patients reported TE. Among these, 52.8% reported early onset, and 50.9% reported moderate hair loss. 11 (20.7%) reported complete hair regrowth within three months, and an additional 32 (60.3%) reported complete regrowth within six months. 4 (7.5%) patients have chronic TE. Female sex (p<0.0001), anemia (p=0.019), hypoproteinemia (p=0.037), and severe pneumonia (p=0.004) were associated with TE. Age, fever, SpO2, CRP levels, in-hospital complications, and raised D-dimers were not associated with TE. Discussion Our study confirmed a high prevalence of COVID-19-associated TE in hospitalized patients. Anemia and hypoalbuminemia were associated with TE, shedding new light on the possible pathogenesis. COVID-19-associated TE occurs earlier than classic TE and has a good prognosis in most patients. However, chronic ТЕ was reported by 7.5%. Even a small incidence of long-term sequelae during a pandemic could have substantial health consequences.

RÉSUMÉ

Telogen effluvium is characterized by excessive hair shedding usually following a stressful event. Ferritin has been used in clinical practice as a biomarker of nonanemic iron deficiency in cases of telogen effluvium. During the years of the COVID19 pandemic, telogen effluvium was reported as a part of post covid manifestations. As ferritin was also a biomarker for inflammation in cases with covid infection, this study was designed to evaluate the value of ferritin in cases with postcovid telogen effluvium one hundred patients recovering from covid 19 for 4-12 weeks were included in the study, detailed drug and laboratory history was obtained and serum ferritin level was measured. the mean serum level of ferritin among telogen effluvium patients was significantly lower than controls (68.52 ± 126 and 137 ± 137.597 ug/L respectively). Patients with telogen effluvium used significantly more azithromycin and ivermectin and significantly less vitamin C, D, lactoferrin and zinc than the controls Although serum ferritin is lower among telogen effluvium patients, it was still higher than the cutoff value for diagnosing nonanemic iron deficiency, we suggest that it will not be a good biomarkers in these cases. Our secondary outcomes showed that dietary supplements used during active infection such as vitamin C, D, lactoferrin and zinc might have a preventive value on postcovid hair loss, while azithromycin and ivermectin could have a negative long term effect on telogen effluvium.

RÉSUMÉ

INTRODUCTION AND OBJECTIVE: Photobiomodulation with the use of light-emitting diodes (LEDs) seems to be a promising option for long COVID. This retrospective study evaluates the efficiency of LED irradiation in the treatment of TE in the course of long COVID in patients with and without androgenetic alopecia. MATERIAL AND METHODS: A retrospective single-centre chart review of patients with post-COVID hair loss was performed. 140 patients enrolled to the study were divided into four groups depending on the type of alopecia and treatment: 1) telogen effluvium with LED therapy (TE LED+), 2) telogen effluvium without LED therapy (TE LED-), 3) telogen effluvium and androgenetic alopecia with LED therapy (TE+AGA LED+), and 4) telogen effluvium and androgenetic alopecia without LED therapy (TE+AGA LED-). Clinical and trichoscopic parameters were compared. RESULTS: After 12 weeks, cessation of hair loss and a negative hair pull test were more common in TE LED+ and TE+AGA LED+ in comparison to the patients without LED therapy (p<0.001, p=0.035, respectively). An increased number of thick hairs and an increased number of hairs within follicular units were more common in patients treated with LED irradiation, regardless of the type of alopecia, compared to the patients without LED therapy. CONCLUSIONS: The study revealed that LED therapy is safe, well tolerated and seems to be a promising therapeutic option for TE in patients with long COVID. It can be used as adjuvant therapy leading to faster reduction of hair loss, enhancing hair regrowth as well as hair shaft thickness and density.

RÉSUMÉ

This article presents a case of a 31-year-old male patient who presented to the outpatient department of the Krasnov Research Institute of Eye Diseases with complaints of diplopia and increased intraocular pressure (IOP) up to 30 mm Hg. The patient had been using minoxidil topically for androgenic alopecia for 8 years. On examination, mild swelling of the bulbar conjunctiva in the upper fornix was revealed; optical coherence tomography showed thinning of the ganglion cell layer, most likely due to moderate myopia. The patient responded well to discontinuation of minoxidil and topical therapy with prostaglandin analogues. After 4 months, an attempt was made to replace topical hypotensive therapy with carbonic anhydrase inhibitors, but the previous hypotensive regimen had to be resumed due to an increase in IOP. During 10 months of observation, no signs of progression were detected according to optical coherence tomography and static perimetry.

RÉSUMÉ

Though it is widely acknowledged that cancer treatments cause hair loss on the scalp, there are limited data on how they affect eyebrow and eyelash hairs. Patients with eyebrow and eyelash loss, or madarosis, seek various treatment options ranging from camouflage techniques with makeup, permanent tattoos, and prescription medications. Though not yet studied in patients with cancer-induced madarosis, techniques such as scalp cooling, cryotherapy, and topical vasoconstrictors are promising preventative options. More robust research is needed to improve both the quality and quantity of available treatment and preventative options. There is a clear need for dermatologists to play a role in supportive oncodermatology for patients who experience eyebrow and eyelash loss secondary to chemotherapy, endocrine therapies, and radiation therapy.

RÉSUMÉ

BACKGROUND/AIM: Hair-follicle keratinocytes contain high levels of cysteine, which is derived from methionine, rapidly proliferate, and form the hair shaft. The high proliferation rate of hair-follicle keratinocytes resembles that of aggressive cancer cells. In the present study, we determined the effect of a methionine-deficient diet on hair loss (alopecia) in mice with or without homocysteine supplementation. MATERIALS AND METHODS: Mice were fed a normal rodent diet (2020X, ENVIGO) (Group 1); a methionine-choline-deficient diet (TD.90262, ENVIGO) (Group 2); a methionine-choline-deficient diet with a 10 mg/kg/day supply of homocysteine administered by intra-peritoneal (i.p.) injection for 2 weeks (Group 3). In Group 2, mice were fed a methionine-choline-deficient diet for an additional 2 weeks but with 10 mg/kg/day of i.p. l-homocysteine and the mice were observed for two additional weeks. Subsequently, the mice were fed a standard diet that included methionine. Hair loss was monitored by photography. RESULTS: After 14 days, hair loss was observed in Group 2 mice on a methionine-restricted diet but not in Group 3 mice on the methionine-restricted diet which received i.p. homocysteine. In Group 2, at 2 weeks after methionine restriction, hair loss was not rescued by homocysteine supplementation. However, after restoration of methionine in the diet, hair growth resumed. Thus, after 2 weeks of methionine restriction, only methionine restored hair loss, not homocysteine. CONCLUSION: Hair maintenance requires methionine in the diet. Future experiments will determine the effects of methionine restriction on hair-follicle stem cells.

RÉSUMÉ

Frontal fibrosing alopecia (FFA) is an increasingly common diagnosis, especially in middle-aged women, and has garnered growing attention in the scientific literature. This variant of lichen planopilaris (LPP) is recognized as a progressive scarring alopecia affecting the frontal and temporal regions of the scalp as well as the eyebrows and occasionally other sites. Although its precise etiology remains elusive, various factors such as genetics, medications, hormonal influences, and environmental exposures-including specific chemicals present in sunscreens-have been implicated in its pathogenesis but without evidence of causality. The potential relationship between contact allergy and FFA has been explored, with some suggesting an increased prevalence of contact allergy among patients diagnosed with FFA. This article aims to explore the potential association between contact allergy and FFA, focusing on the current published literature and implicated allergens.

RÉSUMÉ

Alopecia associated with lupus erythematosus is broadly classified into reversible nonscarring alopecia seen in the acute phase, such as worsening of systemic lupus erythematosus (SLE) and cicatricial alopecia seen in chronic cutaneous lupus erythematosus represented by discoid lupus erythematosus (DLE). In DLE-induced alopecia, early therapeutic intervention before developing scarring alopecia is important, but the condition is often resistant to conventional treatment. Anifrolumab (ANI), a novel therapeutic agent for SLE that inhibits Type I interferon activity, has been shown to be effective against acute skin lesions, including alopecia, in patients with SLE. However, there are very few reports on the effect of ANI on alopecia due to DLE. We report on a 27-year-old Japanese woman with SLE whose alopecia due to chronic DLE was refractory to topical therapy and systemic therapy with oral glucocorticoid, multiple immunosuppressants, and belimumab for ∼8 years after onset and whose alopecia improved with ANI. ANI can be considered to be an effective treatment option in lupus patients presenting with alopecia due to DLE, even in the chronic refractory stage.

RÉSUMÉ

BACKGROUND AND RATIONALE: Cicatricial alopecia not only affects patients' appearance but also has negative effects on their physical and mental well-being, as well as their daily lives. Therefore, it is essential to provide proactive treatment to patients. OBJECTIVE: To explore the clinical effects of autologous follicular unit extraction (FUE) transplantation in the treatment of secondary scarring alopecia caused by burn, and to evaluate its effectiveness. METHODS: A retrospective observational study has been conducted, which included 41 patients with secondary scarring alopecia caused by burn. All patients underwent initial autologous FUE hair transplantation surgery, and the occurrence of postoperative complications was monitored. Patient satisfaction was evaluated after 12 months post-surgery. RESULTS: Satisfaction assessments were conducted for all 41 patients. Out of the total, 31 individuals expressed being very satisfied, 7 individuals reported being satisfied, and 3 individuals indicated being not very satisfied. Among the patients, 3 experienced complications, including herpes in the donor area for one patient, temporary hair loss for another patient, and thick scab for the third patient. CONCLUSION: FUE hair transplantation yields positive results for secondary scarring alopecia caused by burn. It offers natural hair growth patterns, minimal trauma, quick recovery, high patient satisfaction, and few complications.

RÉSUMÉ

Introduction: trichoscopic and histopathological evaluation of non-scarring systemic lupus erythematosus (SLE) alopecia is uncommon. We aimed to document the prevalence, pattern of hair loss, trichoscopic and histopathologic differences between systemic lupus erythematosus patients with and without hair loss. Methods: this was a cross-sectional comparative study of 75 systemic lupus erythematosus patients, 36 with hair loss from February to December 2020. Trichoscopic evaluation was conducted on all 75 patients. Twenty-three patients (12 with hair loss and 11 without) had scalp biopsies with mucin deposit evaluation. Disease activity was documented using the SLE disease activity index. Data was analyzed using SPSS 22. Results: the mean age of the patients was 33.7 ± 12.4 years. Non-scarring alopecia was observed in 48%. The pattern of hair loss was <4 patches in 44.4%, mild diffuse in 25%, and severe diffuse in 30.6%. Disease activity was mild in 38.9%. Hair shaft changes included thin hair (97.2%), decreased number of hairs per follicular unit (97.2%), hypopigmented hair (85.7%), and follicular red dots (27.8%). Significant differences between the two groups were; a reduction in size and number of sebaceous glands on histopathology, hair shaft, and scalp pigmentary changes in the hair loss group. Conclusion: the prevalence of non-scaring alopecia is high in SLE patients with patchy type as the commonest pattern. Trichoscopic and histopathologic differences exist in SLE patients with and without hair loss and the normal-appearing scalp in SLE patients is involved in the inflammatory process. Hair shaft thinning, hypopigmentation, and scalp pigmentary changes occur in SLE.

RÉSUMÉ

BACKGROUND: Smoking-which often refers to recreational consumption of the nicotine-containing tobacco-is deemed a risk factor for both the development of and worsening of androgenetic alopecia (AGA). However, there is no published meta-analysis study on the effect of smoking on AGA; so, we quantitatively synthesized the evidence base pertaining to the recreational activity and this form of hair loss in men. METHODS: We systematically searched PubMed and Scopus to identify published studies with suitable data, and pairwise meta-analyses were conducted. RESULTS: Our search identified eight studies-and the data thereof were used across four meta-analyses. We found that ever smokers are significantly (p < 0.05) more likely, than never smokers, to develop AGA (pooled odds ratio (OR) = 1.82, 95% confidence interval (CI): 1.55-2.14). Our results showed that the odds of developing AGA are significantly (p < 0.05) higher in men who smoke at least 10 cigarettes per day, than in their counterparts who smoke up to 10 cigarettes per day (pooled OR = 1.96, 95% CI: 1.17-3.29). For men with AGA, the odds of disease progression are significantly (p < 0.05) higher among ever smokers than in never smokers (pooled OR = 1.27, 95% CI: 1.01-1.60). We found no significant (p ≥ 0.05) association between smoking intensity and disease progression. CONCLUSIONS: Findings from the current study-which is the first meta-analysis to our knowledge reviewing the association between AGA and the extent of smoking, can guide further research and update clinical practice guidelines.

RÉSUMÉ

INTRODUCTION: Hyperandrogenism is a clinical state consequent to excess androgen production by the ovary, adrenals, or increased peripheral conversion of androgens. The varied manifestations of hyperandrogenism include seborrhea, acne, infertility, hirsutism, or overt virilization of which adult female acne, hirsutism, and female pattern hair loss are of clinical relevance to dermatologists. AREAS COVERED: We limited our narrative review to literature published during period from 1 January 1985 to Dec 2022 and searched PubMed/MEDLINE, Web of Science (WOS), Scopus, and Embase databases with main search keywords were 'Hyperandrogenism,' 'Female,' 'Biochemical,' 'Dermatological', and 'Dermatology.' We detail the common etiological causes, nuances in interpretation of biochemical tests and imaging tools, followed by an algorithmic approach which can help avoid extensive tests and diagnose the common causes of hyperandrogenism. EXPERT OPINION: Based on current data, total testosterone, sex hormone binding globulin, DHEAS, prolactin, free androgen index, and peripheral androgenic metabolites like 3-alpha diol and androsterone glucuronide are ideal tests though not all are required in all patients. Abnormalities in these biochemical investigations may require radiological examination for further clarification. Total testosterone levels can help delineate broadly the varied causes of hyperandrogenism. Serum AMH could be used for defining PCOM in adults.
