Clinical presentations, systemic inflammation response and ANDC scores in hospitalized patients with COVID-19.

The association of anosmia/ageusia with a positive severe respiratory syndrome coronavirus 2 (SARS-CoV-2) test is well-established, suggesting these symptoms are reliable indicators of coronavirus disease 2019 (COVID-19) infection. This study investigates the clinical characteristics and systemic inflammatory markers in hospitalized COVID-19 patients in Taiwan, focusing on those with anosmia/ageusia. We conducted a retrospective observational study on 231 hospitalized COVID-19 patients (alpha variant) from April to July 2021. Clinical symptoms, dyspnea grading, and laboratory investigations, including neutrophil-lymphocyte ratios (NLRs), platelet-lymphocyte ratios (PLRs), and ANDC scores (an early warning score), were analyzed. Cough (64.1%), fever (58.9%), and dyspnea (56.3%) were the most common symptoms, while anosmia/ageusia affected 9% of patients. Those with anosmia/ageusia were younger, had lower BMI, lower systemic inflammatory markers, and better ANDC scores than those without these symptoms. Female patients exhibited lower NLR values and ANDC scores compared to male patients (all p < 0.05). Multivariable regression analysis demonstrated significant associations between NLR and CRP and ferritin levels (all p < 0.01), and between PLR and ESR and ferritin levels (p < 0.01). Categorized ANDC scores significantly correlated with the total hospital length of stay (all p < 0.05). Despite ethnic differences in the prevalence of anosmia/ageusia, our study highlights similar clinical presentations and inflammatory profiles to those observed in Western countries. The ANDC score effectively predicted hospital stay duration. These findings suggest that anosmia/ageusia may be associated with less severe disease and a lower inflammatory response, particularly in younger and female patients. The ANDC score can serve as a valuable prognostic tool in assessing the severity and expected hospital stay of COVID-19 patients.

Clinical Presentations and Outcome Studies of Cranial Nerve Involvement in Herpes Zoster Infection: A Retrospective Single-Center Analysis.

Varicella-zoster virus (VZV) infection can cause chickenpox and herpes zoster. It sometimes involves cranial nerves, and rarely, it can involve multiple cranial nerves. We aimed to study clinical presentations of cranial nerve involvement in herpes zoster infection. We included patients who had the diagnosis of herpes zoster infection and cranial nerve involvement. The diagnosis was confirmed by typical vesicles and a rash. We excluded patients who had cranial neuralgias or neuropathies but without typical skin lesions (zoster sine herpete or post-herpetic neuralgia). We included 330 patients (mean age, 55.0 ± 17.0 years) who had herpes zoster with cranial nerve involvement, including 155 men and 175 women. Most frequently involved cranial nerves were the trigeminal nerve (57.9%), facial nerve (52.1%), and vestibulocochlear nerve (20.0%). Other involved cranial nerves included the glossopharyngeal nerve (0.9%), vagus nerve (0.9%), oculomotor nerve, trochlear nerve, and abducens nerve (each 0.3%, respectively). One hundred and seventy patients (51.5%) had only sensory symptoms/signs; in contrast, 160 patients (48.5%) had both sensory and motor symptoms/signs. Of those 160 patients, sensory preceded motor symptoms/signs in 64 patients (40.0%), sensory and motor symptoms/signs occurred simultaneously in 38 patients (23.8%), and motor preceded sensory symptoms/signs in 20 patients (12.5%). At one month after herpes zoster infection, vesicles and rash disappeared in 92.6% of patients; meanwhile facial palsy showed a significant improvement in 81.4% of patients (p < 0.05). Cranial motor neuropathies are not infrequent in herpes zoster infections. Multiple cranial nerve involvement frequently occurred in Ramsay Hunt syndrome. We found a significantly increased seasonal occurrence of cranial nerve zoster in spring rather than summer. Cranial motor nerves were affected while the hosts sometimes had a compromised immune system.
