BACKGROUND
The COVID-19 pandemic has claimed many lives and continues to impact individuals through post-COVID-19 conditions. Osteonecrosis of the femoral head (ONFH) is increasingly recognized as a major post-COVID-19 complication, yet most studies are limited to case reports and small series. This study aimed to evaluate COVID-19-related factors potentially contributing to ONFH development in post-COVID-19 patients.
METHODS
A retrospective analysis was conducted on 84 patients with ONFH and a confirmed history of COVID-19. Baseline characteristics were collected, and patients were categorized into the following groups for comparative analysis: (1) vaccinated vs. unvaccinated, (2) unilateral vs. bilateral ONFH, (3) dexamethasone (DEX) and methylprednisolone (MPS) vs. DEX therapy, and (4) Association Research Circulation Osseus (ARCO) stage 2 vs. stage 3. Group differences and associations were analyzed.
RESULTS
The DEX and MPS-treated group had a greater extent of COVID-19 lung involvement compared to the DEX-treated group (59.2% vs. 36.3%, p = 0.002), as well as longer hospital stays in both general ward (14.2 days vs. 10.6 days, p = 0.018) and ICU (5.4 days vs. 3 days, p = 0.017). The DEX and MPS-treated group also had a longer duration of steroid therapy (19.3 days vs. 12.3 days, p < 0.001) and received higher DEX-equivalent cumulative steroid doses (380 mg vs. 125 mg, p < 0.001). Notably, ONFH symptoms developed earlier in the DEX and MPS-treated group compared to the DEX-treated group (7.5 months vs. 12 months, p = 0.004). Multivariable logistic regression analysis identified cumulative steroid dose as the sole predictor of ONFH severity (OR: 1.015, 95% CI: 1.001-1.028, p = 0.032), with ARCO stage 3 patients receiving higher cumulative steroid doses than stage 2 patients (240 mg vs. 126 mg, p = 0.018).
CONCLUSIONS
Our study demonstrated that cumulative steroid dose is the primary determinant of ONFH severity in post-COVID-19 patients. Additionally, combined use of corticosteroids may accelerate the onset of ONFH, highlighting the need for cautious steroid management in COVID-19 patients.
背景
新冠疫情已导致许多人死亡，并通过新冠后状况持续影响个人。股骨头坏死（ONFH）日益被认为是新冠后的一种主要并发症，但大多数研究仅限于病例报告和小样本系列研究。本研究旨在评估可能导致新冠后患者发生ONFH的新冠相关因素。
方法
对84例确诊有新冠病史的ONFH患者进行回顾性分析。收集基线特征，并将患者分为以下几组进行比较分析：（1）接种疫苗组与未接种疫苗组；（2）单侧ONFH与双侧ONFH；（3）地塞米松（DEX）和甲泼尼龙（MPS）联合治疗组与DEX治疗组；（4）骨循环研究协会（ARCO）2期与3期。分析组间差异和关联。
结果
与DEX治疗组相比，DEX和MPS联合治疗组的新冠肺部受累程度更高（59.2%对36.3%，p = 0.002），在普通病房的住院时间也更长（14.2天对10.6天，p = 0.018），在重症监护病房的住院时间也更长（5.4天对3天，p = 0.017）。DEX和MPS联合治疗组的类固醇治疗持续时间也更长（19.3天对12.3天，p < 0.001），接受的DEX等效累积类固醇剂量更高（380毫克对125毫克，p < 0.001）。值得注意的是，与DEX治疗组相比，DEX和MPS联合治疗组的ONFH症状出现更早（7.5个月对12个月，p = 0.004）。多变量逻辑回归分析确定累积类固醇剂量是ONFH严重程度的唯一预测因素（OR：1.015，95%CI：1.001 - 1.028，p = 0.032），ARCO 3期患者接受的累积类固醇剂量高于2期患者（240毫克对126毫克，p = 0.018）。
结论
我们的研究表明，累积类固醇剂量是新冠后患者ONFH严重程度的主要决定因素。此外，联合使用皮质类固醇可能会加速ONFH的发病，这突出了对新冠患者进行谨慎类固醇管理的必要性。
