ABSTRACT
IMPORTANCE: Identifying undetected clinical signs is imperative in the prevention of SARS-CoV-2. OBJECTIVE: To establish the prevalence of clinical gustatory and olfactory dysfunctions in patients with COVID-19 pneumonia. Clinical outcomes and recovery rates associated with gustatory and olfactory dysfunctions were also assessed. DESIGN: A prospective study was performed in 80 patients admitted to Hospital Clínic of Barcelona (Spain) for COVID-19 pneumonia. Patients were re-evaluated in the ward daily until discharge. Gustatory and olfactory dysfunction symptoms were retrospectively collected from emergency room (ER) charts after first assessments. Follow-up was performed in telemedicine consultation. SETTING: The single-centre study was performed in a hospitalisation ward at a university hospital. PARTICIPANTS: Consecutive patients meeting hospitalisation criteria for COVID-19 pneumonia were eligible. Study exclusion criteria were patients who could not speak, had previous gustatory and olfactory dysfunctions or whose PCR tests for SARS-CoV-19 were negative. INTERVENTIONS: Systematic assessment of gustatory and olfactory symptoms with standardised questions. OUTCOMES: Prevalence of gustatory and olfactory dysfunctions in patients with COVID-19 pneumonia. RESULTS: Of the 80 study subjects, 62.5% were male and the median age was 57 years. Half of the cohort (n=40) presented with comorbidities. The prevalence of chemosensitive disorder was 73.8% (n=59) (95% CI: 63.8 to 83.8), although self-reported symptoms were recorded in only 26.3% (n=21) of patients in the ER. Gustatory and olfactory dysfunctions were observed in 58.8% (n=47) and 55% (n=44) of cases, respectively. They were also the first symptoms in 25% (n=20) of patients. Anosmia was associated with ageusia, OR: 7, 95% CI: 2.3 to 21.8, p=0.001). No differences in clinical outcomes were observed when patients with and without gustatory and olfactory dysfunctions were compared. Recovery rates were 20% (n=10) and 85% (n=42) at days 7 and 45, respectively. CONCLUSION: The prevalence of gustatory and olfactory dysfunctions in COVID-19 pneumonia was much higher than in self-report. Presence of gustatory and olfactory dysfunctions was not a predictor of clinical outcomes.

BACKGROUND: It is unclear how characteristics, risk factors, and incidence of coronavirus disease 2019 (COVID-19) in people living with HIV (PLWH) differ from the general population. METHODS: Prospective observational single-center cohort study of adult PLWH reporting symptoms of COVID-19. We assessed clinical characteristics, risk factors for COVID-19 diagnosis and severity, and standardized incidence rate ratio for COVID-19 cases in PLWH cohort and in Barcelona. RESULTS: From 1 March 2020 to 10 May 2020, 53 out of 5683 (0.9% confidence interval 0.7-1.2%) PLWH were diagnosed with COVID-19. Median age was 44 years, CD4 T cells were 618/µl and CD4/CD8 was 0.90. All but two individuals were virologically suppressed. Cough (87%) and fever (82%) were the most common symptoms. Twenty-six (49%) were admitted, six (14%) had severe disease, four (8%) required ICU admission, and two (4%) died. Several laboratory markers (lower O2 saturation and platelets, and higher leukocytes, creatinine, lactate dehydrogenase, C reactive protein, procalcitonin, and ferritin) were associated with COVID-19 severity. No HIV or antiretroviral-related factors were associated with COVID-19 diagnosis or severity. Standardized incidence rate ratios of confirmed or confirmed/probable COVID-19 in PLWH were 38% (95% confidence interval 27-52%, Pâ<â0.0001) and 33% (95% confidence interval 21-50%, Pâ<â0.0001), respectively relative to the general population. CONCLUSION: PLWH with COVID-19 did not differ from the rest of the HIV cohort. Clinical presentation, severity rate, and mortality were not dependent on any HIV-related or antiretroviral-related factor. COVID-19 standardized incidence rate was lower in PLWH than in the general population. These findings should be confirmed in larger multicenter cohort studies.
