Telogen effluvium (TE) is self limiting diffuse hair loss occurring 3-4 months after a triggering event. There is scarcity of data on TE as possible sequelae of COVID-19.
We assessed 113 cases of TE occurring after SARS-CoV-2 infection as a retrospective study.
Most of the patients belonged to the age group 18-30 years and were females (85.8%). Most of the patients (92%) had acute TE. The median duration of hair loss was 2 months. Trichodynia and pruritus were the common associated complaints. Hair pull test was positive in 54.9% patients. Trichoscopy showed short regrowing hairs in 61.2% patients and empty hair follicles in 77.9% patients. Ferritin, vitamin D and Vitamin B12 deficiency was seen in 27.4%, 38.1% and 20.4% patients respectively. TE was seen more commonly with symptomatic COVID infection (93% patients).
TE occurring after SARS-CoV-2 infection calls for assessment of micronutrient deficiency, as there appears to be an association between COVID-19 infection and nutritional deficiency. Although acute TE is the most common presentation, relapse in chronic TE might also occur as sequelae of COVID-19 infection.
休止期脱发（TE）是一种自限性弥漫性脱发，发生在触发事件后的3 - 4个月。关于TE作为新冠病毒病可能后遗症的数据较少。
我们进行了一项回顾性研究，评估了113例新冠病毒感染后发生的休止期脱发病例。
大多数患者年龄在18 - 30岁之间，且为女性（85.8%）。大多数患者（92%）患有急性休止期脱发。脱发的中位持续时间为2个月。毛发疼痛和瘙痒是常见的相关主诉。54.9%的患者拔毛试验呈阳性。毛发镜检查显示，61.2%的患者有短的再生毛发，77.9%的患者有毛囊空虚。分别有27.4%、38.1%和20.4%的患者存在铁蛋白、维生素D和维生素B12缺乏。休止期脱发在有症状的新冠病毒感染患者中更常见（93%的患者）。
新冠病毒感染后发生的休止期脱发需要评估微量营养素缺乏情况，因为新冠病毒感染与营养缺乏之间似乎存在关联。虽然急性休止期脱发是最常见的表现，但慢性休止期脱发复发也可能作为新冠病毒感染的后遗症出现。
