RESUMO
Castleman disease (CD), a heterogenous lymphoproliferative disorder resulting from immune dysregulation, is a very rare disease in clinical practice. The clinical spectrum of Castleman disease is wide and its treatment options are mostly based on case reports and case series. To date, two clinical and four histological types have been described. It has recently been successfully demonstrated that the pathogenesis of multicentric Castleman disease (MCD) has a direct association with human immunodeficiency virus (HIV) and human herpes virus 8 (HHV-8) infection which is why further studies are necessary. Here, we report an unusual case of MCD not associated with HIV and having a histological diagnosis of the hyaline vascular type that presented with acute renal impairment and subcutaneous abnormal lymphatic proliferation.
RESUMO
A large number of coronavirus disease 2019 (COVID-19) recovered patients are suffering from related symptoms. We conducted telephone interviews with 186 COVID-19 recovered medical doctors to determine the post-COVID symptoms, duration, and associated risk factors. About 70% of participants had at least one acute post-COVID symptom, including fatigue (43.0%), sleep disturbance (13.4%), lack of concentration (11.8%), breathing difficulty (10.2%), headache (6.5%), and muscle pain (6.5%). However, about 24% of participants reported having long post-COVID symptoms. Logistic regression analysis showed that female sex (odds ratio {OR}, 2.79; 95% CI, 1.28-6.06; p-value: 0.010) and comorbid conditions (OR, 2.28; 95% CI, 1.08-4.79; p: value, 0.030) are risk factors for the long post-COVID symptoms.
