Famotidine's Possible Cutaneous Rash in COVID-19 Patients: An Adverse Effect Case Series.

BACKGROUND: Various cutaneous manifestations have been observed in patients with COVID-19 infection. However, the side effects on skin of the medications used for COVID-19, such as famotidine, have not been studied. OBJECTIVE: This case series aims to present challenges in defining cutaneous manifestations of famotidine in the context of COVID-19. CASE PRESENTATION: We identified patients from Imam Khomeini hospital complex who were admitted to the ward due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), were taking famotidine and having cutaneous rash. Clinical data were obtained through observation and intervention. DISCUSSION: We found 4 SARS-CoV-2 patients with cutaneous manifestations. The mean (±SD) age of the patients was 57±2 years, 3 patients were men, and their COVID-19 symptoms appeared 10±3 days before admission. The most common symptoms were cough and shortness of breath. All the patients were admitted for hypoxemic respiratory failure. Patients received famotidine for gastrointestinal prophylaxis, and all 4 patients developed Acral macular mountainous skin lesions in the upper and lower extremities, then we discontinued famotidine and lesions were recovered completely in all patients. CONCLUSION: These cases prompted us to inform clinicians about cutaneous complications of famotidine in COVID-19 patients.

Predictors of the prolonged recovery period in COVID-19 patients: a cross-sectional study.

BACKGROUND: The clinical course of COVID-19 may vary significantly. The presence of comorbidities prolongs the recovery time. The recovery in patients with mild-to-moderate symptoms might take 10 days, while in those with a critical illness or immunocompromised status could take 15 days. Considering the lack of data about predictors that could affect the recovery time, we conducted this study to identify them. METHODS: This cross-sectional study was implemented in the COVID-19 clinic of a teaching and referral university hospital in Tehran. Patients with the highly suggestive symptoms who had computed tomography (CT) imaging results with typical findings of COVID-19 or positive results of reverse transcriptase-polymerase chain reaction (RT-PCR) were enrolled in the study. Inpatient and outpatient COVID-19 participants were followed up by regular visits or phone calls, and the recovery period was recorded. RESULTS: A total of 478 patients were enrolled. The mean age of patients was 54.11 ± 5.65 years, and 44.2% were female. The median time to recovery was 13.5 days (IQR: 9). Although in the bivariate analysis, multiple factors, including hypertension, fever, diabetes mellitus, gender, and admission location, significantly contributed to prolonging the recovery period, in multivariate analysis, only dyspnea had a significant association with this variable (p = 0.02, the adjusted OR of 2.05; 95% CI 1.12-3.75). CONCLUSION: This study supports that dyspnea is a predictor of recovery time. It seems like optimal management of the comorbidities plays the most crucial role in recovery from COVID-19.

CT-scan findings of COVID-19 pneumonia based on the time elapsed from the beginning of symptoms to the CT imaging evaluation: a descriptive study in Iran.

Background. Coronavirus disease 2019 (COVID-19) was initially detected in Wuhan city, China. Chest CT features of COVID-19 pneumonia have been investigated mostly in China, and there is very little information available on the radiological findings occurring in other populations. In this study, we aimed to describe the characteristics of chest CT findings in confirmed cases of COVID-19 pneumonia in an Iranian population, based on a time classification.Methods. Eighty-nine patients with COVID-19 pneumonia, confirmed by a real-time RT-PCR test, who were admitted to non-ICU wards and underwent a chest CT scan were retrospectively enrolled. Descriptive evaluation of radiologic findings was performed using a classification based on the time interval between the initiation of the symptoms and chest CT-scan.Results. The median age of patients was 58.0 years, and the median time interval from the onset of symptoms to CT scan evaluation was 7 days. Most patients had bilateral (94.4%) and multifocal (91.0%) lung involvement with peripheral distribution (60.7%). Also, most patients showed involvement of all five lobes (77.5%). Ground-glass opacities (GGO) (84.3%) and mixed GGO with consolidation (80.9%) were the most common identified patterns. We also found that as the time interval between symptoms and CT scan evaluation increased, the predominant pattern changed from GGO to mixed pattern and then to elongated-containing and band-like-opacities-containing pattern; on the other hand, the percentage of lung involvement increased.Conclusions. Bilateral multifocal GGO, and mixed GGO with consolidation were the most common patterns of COVID-19 pneumonia in our study. However, these patterns might change according to the time interval from symptoms.

Prevalence of COVID-19-like Symptoms among People Living with HIV, and Using Antiretroviral Therapy for Prevention and Treatment.

BACKGROUND: COVID-19 has spread globally with remarkable speed, and currently, there is limited data available exploring any aspect of the intersection between HIV and SARSCoV- 2 co-infection. OBJECTIVE: To estimate the prevalence of clinical symptoms associated with COVID-19 among people living with HIV (PLWH) in Tehran, Iran. DESIGN: Cross-sectional study. METHODS: A total of 200 PLWH were recruited through the positive club via sampling, and completed the symptom-based questionnaire for COVID-19, which was delivered by trained peers. RESULTS: Of 200 participants, respiratory symptoms, including cough, sputum, and shortness of breath, were the most prevalent among participants, but only one person developed symptoms collectively suggested COVID-19 and sought treatments. CONCLUSION: It appears that existing infection with HIV or receiving antiretroviral treatment (ART) might reduce the susceptibility to the infection with SARS-CoV-2 or decrease the severity of the infection acquired. Further research is needed to understand causal mechanisms.
