Treatment of chronic telogen effluvium with oral minoxidil: A retrospective study.

ABSTRACT: Background: Chronic telogen effluvium (CTE) may be primary or secondary to various causes, including drug reaction, nutritional deficiency and female pattern hair loss (FPHL). Oral minoxidil stimulates hair growth, and topical minoxidil is used in the treatment of FPHL and male androgenetic alopecia. minoxidil has not been used to treat CTE. This study aimed to assess the treatment of CTE with once daily oral minoxidil. Methods: Women with a diagnosis of CTE based on >6 month history of increased telogen hair shedding, no visible mid frontal scalp hair loss (Sinclair stage 1) and no hair follicle miniaturization on scalp biopsy were treated with once daily oral minoxidil. Hair shedding scores (HSS) at baseline, 6 and 12 months were analysed using the Wilcoxon rank sum test for pair-wise comparisons. Results: Thirty-six women were treated with oral minoxidil (range, 0.25-2.5 mg) daily for 6 months. Mean age was 46.9 years (range 20-83), HSS at baseline was 5.64, and duration of diagnosis was 6.55 years (range 1-27). There was a reduction in mean HSS scores from baseline to 6 months of 1.7 (p<0.001) and baseline to 12 months of 2.58 (p<0.001). Five women who described trichodynia at baseline, noted improvement or resolution within 3 months. Mean change in blood pressure was minus 0.5 mmHg systolic and plus 2.1 mmHg diastolic. Two patients developed transient postural dizziness that resolved with continued treatment. One patient developed ankle oedema. Thirteen women developed facial hypertrichosis. For 6 patients this was mild and did not require treatment; 4 had waxing of their upper lip or forehead; 3 had laser hair removal. No patients developed any haematological abnormality. All 36 women completed 12 months of treatment. Conclusions: Once daily oral minoxidil appears to reduce hair shedding in CTE. Placebo controlled studies are recommended to further assess this response.

Project description:COVID-19 is a febrile, infectious illness that has previously been associated with telogen effluvium (TE). However, to date, no study has been conducted to determine the incidence of TE in those who have had COVID-19. To assess the frequency of TE in post-COVID-19 patients and the correlation between the development of TE and the severity of COVID-19, to understand whether emotional stress or medications are responsible for the development of TE. Totally 204 patients with a history of SARS-CoV-2 infection in the last 3 months were included in the study. The diagnosis of TE was made by history of excessive hair shedding, hair pull test, diffuse or bitemporal thinning, and absence of anisotrichosis in trichoscopy. Patients who did not have any TE cause other than COVID-19 and whose hair loss started after COVID-19 were considered as "COVID-19 associated TE (CATE)." We found TE in 75 (36.7%) cases and androgenetic alopecia (AGA) in 85 (41.7%) cases. CATE was present in 27.9% of cases and developed on average 53.76 (± 23.772) days after COVID-19 real-time reverse transcription polymerase chain reaction (RT-PCR) positivity. The proportion of patients with CATE was numerically higher in hospitalized patients compared to outpatients (31.7% vs. 24.3%; p = 0.238); and significantly higher in women compared to men (42.3% vs. 6.2%; p < 0.001), in patients with hypertension compared to those without hypertension (40.4% vs. 23.1%; p = 0.014), and in patients who had respiratory symptoms compared to those who had not (31.7% vs. 14.0%; p = 0.021). The patients with and without CATE were similar in terms of stress level and usage of COVID-19 medications. Patients with AGA had a higher rate of hospitalization (69.4% vs. 35.3%; p < 0.001) and a higher incidence of fever (69.4% vs. 54.6%; p = 0.033) during COVID-19, compared to those without. TE developed in approximately one-quarter of people who have had COVID-19, and our study is the first to detect it. The time to onset of CATE, which was 7-8 weeks after the SARS-CoV-2 RT-PCR positivity, was not much different from post-infectious TE. Patients with severe COVID-19 seem to be more prone to develop TE. The presence of AGA is associated with a more severe COVID-19. During the pandemic, clinicians should consider a previous SARS-CoV-2 infection in patients presenting with hair loss.

Project description:BackgroundScalp hair loss (alopecia) in women is a common ageing and senescing condition. It usually presents as androgenetic alopecia (AGA) or telogen effluvium (TE) and often has pronounced psychological consequences. ALRV5XR is a novel treatment aiming to regenerate a normal hair phenotype by targeting multiple molecular pathways linked to hair growth promotion and hair follicle stem cell activation. The primary objectives of this 24-week trial were to evaluate the safety and efficacy of ALRV5XR in terminal hair (TH) regrowth in women with AGA or TE.MethodsThis randomised, double-blind, placebo-controlled trial was performed in a USA community clinic. Healthy women 18-65 years of age with AGA or TE of Ludwig classification I-II and Fitzpatrick skin type I-VI were enrolled. They were allocated in a 1:1 ratio into ALRV5XR or placebo treatment groups using a random number table. Masked dermatologist assessments, phototrichograms and blood samples were obtained at baseline, 12 and 24 weeks. Subjects were given a masked treatment regimen of oral capsules, shampoo, conditioner and follicle serum for daily administration. Main outcomes were absolute and per cent changes in TH density and response rates. The trial was registered with clinicaltrials.gov (NCT04450602) and is completed.Findings46 subjects (23 ALRV5XR, 23 placebo) were enrolled between April 3 and October 20, 2018. Five subjects dropped out and two were non-compliant. Thirty-nine subjects completed the trial (18 ALRV5XR, 21 placebo). At 24 weeks, the absolute change in TH density improved by 30·1THs/cm2 (95% CI: 15·1-45·1; p=0·0002), and the relative density increased by 19·7% (95% CI: 8·0%-31·4%; p=0·0016). The odds ratio for being a responder (≥0 change) was 2·7. Efficacy increased 133% from week 12 to 24. Efficacy outcomes were similar in AGA and TE subjects. 66·7% of the ALRV5XR group responded by regrowing 40THs/cm2 or more hair. No adverse events were reported.InterpretationIn women with AGA or TE, ALRV5XR treatment significantly increased hair regrowth without adverse events. ALRV5XR displayed a multi-fold improved efficacy and response rate when compared to published trials of standard therapy. Progressive acceleration of TH regrowth suggests regeneration of the structure and function of non-productive telogen follicles and prolonged treatment may restore a normal hair phenotype.
