: With the emergence of the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the whole world is suffering from atypical pneumonia, which resulted in more than 559,047 deaths worldwide. In this time of crisis and urgency, the only hope comes from new candidate vaccines and potential antivirals. However, formulating new vaccines and synthesizing new antivirals are a laborious task. Therefore, considering the high infection rate and mortality due to COVID-19, utilization of previous information, and repurposing of existing drugs against valid viral targets have emerged as a novel drug discovery approach in this challenging time. The transmembrane spike (S) glycoprotein of coronaviruses (CoVs), which facilitates the virus’s entry into the host cells, exists in a homotrimeric form and is covered with N-linked glycans. S glycoprotein is known as the main target of antibodies having neutralizing potency and is also considered as an attractive target for therapeutic or vaccine development. Similarly, targeting of N-linked glycans of S glycoprotein envelope of CoV via carbohydrate-binding agents (CBAs) could serve as an attractive therapeutic approach for developing novel antivirals. CBAs from natural sources like lectins from plants, marine algae and prokaryotes and lectin mimics like Pradimicin-A (PRM-A) have shown antiviral activities against CoV and other enveloped viruses. However, the potential use of CBAs specifically lectins was limited due to unfavorable responses like immunogenicity, mitogenicity, hemagglutination, inflammatory activity, cellular toxicity, etc. Here, we reviewed the current scenario of CBAs as antivirals against CoVs, presented strategies to improve the efficacy of CBAs against CoVs; and studied the molecular interactions between CBAs (lectins and PRM-A) with Man9 by molecular docking for potential repurposing against CoVs in general, and SARSCoV- 2, in particular.

Abstract Background Predictions have been made that Africa would be the most vulnerable continent to the novel Coronavirus disease 2019 (COVID-19). Interestingly, the spread of the disease in Africa seems to have been delayed and initially slower than in many parts of the world. Here we report on two cases of respiratory distress in our region before the official declaration of the disease in December 2019, cases which in the present times would be suspect of COVID-19. Case presentation These two cases (one 55-year-old man and one 25-year-old woman) of acute respiratory distress secondary to atypical pneumonia were seen in Bukavu, in Eastern Democratic Republic of the Congo (DRC), between September and December 2019. One patient had returned from China and the other had close contacts with travellers from China in the 2 weeks prior to the onset of symptoms. In either case, the aetiology could not be accurately determined. However, the two cases presented a clinical picture (progressive dyspnoea, preceded by dry cough and fever) and laboratory changes (procalcitonin within the normal range, slight inflammation, and lymphopenia) compatible with a viral infection. The chest X-ray series of the first patient showed lesions (reticulations, ground glass, and nodules ≤6 mm) similar to those currently found in COVID-19 patients. In addition, unlike the 25-year-old female patient who had no comorbidity, the 55-year-old male patient who had hypertension as comorbidity, developed a more severe acute respiratory distress which progressed to death. Conclusion These cases bring to the attention the fact that COVID-19-like syndromes may have already been present in the region months before the official beginning of the pandemic. This also brings to question whether a prior presence of the disease or infections with related virus may account for the delayed and less extensive development of the pandemic in the region.

China officially recognized atypical pneumonia outbreak in December 2019; on 11 March 2020, the World Health Organization declared COVID-19 as a pandemic that is produced by a new coronavirus, named SARS-CoV-2, of rapid transmissibility, which can be asymptomatic, with mild to severe respiratory symptoms, and with cardiovascular, neurological, gastrointestinal, and cutaneous complications. Considering that the pandemic prolonged more than initially expected was prognostic, it is essential for the medical community to identify the signs and symptoms of COVID-19. Thus, this work’s objectives were to present cases of cutaneous lesions observed in COVID-19 Mexican patients. We register cutaneous lesions in COVID-19 patients referred from internal medicine and otorhinolaryngology services to dermatology. We presented four interesting cases with cutaneous lesions, including exanthema morbilliform, urticaria, chilblains, ecchymosis, and facial edema, and review the available literature. The most frequent cutaneous markers are rash, chilblains, and urticaria. Skin lesions may be the first manifestation of COVID-19, accompany initial respiratory symptoms, or appear during the disease course. Symptoms associated with vascular changes (livedo reticularis and vasculitis) are considered of poor prognosis.

Abstract Introduction/Objective Acute interstitial pneumonia (AIP) is a rare disease clinically characterized by rapidly progressing respiratory failure in individuals with no history of respiratory illness or other inciting factors. While most often diagnosed in middle-aged adults, it may present in any age group. Initial presentation is described as influenza- like, and respiratory failure requiring ventilatory support often progresses within weeks to months. Prognosis is poor, with an estimated mortality rate approaching 80% without treatment. Methods We present the case of a 44-year-old male nonsmoker with no significant medical history, who presented in 2018 with 1.5 months of dyspnea and headache initially diagnosed as atypical pneumonia. Chest imaging revealed bilateral opacities; however, microbial workup revealed no evidence of infectious etiology. Autoimmune serology studies were likewise unrevealing. Despite aggressive supportive and medical management, he deteriorated to respiratory failure and succumbed. Results At autopsy, the lungs were symmetrically congested and edematous (combined weight 2,340 g) but free of evident consolidation or discrete lesions. Microscopic examination revealed diffuse alveolar damage with extensive hyaline membrane formation, interstitial edema, and fibroblastic proliferation. The vasculature was severely congested, and the alveoli contained hemorrhage and scattered macrophages. No fungal or mycobacterial elements were identified by staining. Based on the histologic features and clinical context, the diagnosis of AIP was made. Conclusion AIP is a rare, aggressive, and diagnostically challenging disease that includes a broad range of both clinical and histologic differentials. Timely recognition and intervention with aggressive respiratory support and high- dose glucocorticoids are the mainstays of clinical management. The diagnostic role of histology is significant, but hinges on early clinical consideration of AIP as disease progression may later preclude the biopsy procedure. We share this case to raise awareness of this rapidly progressive and diagnostically troubling interstitial lung disease while emphasizing the importance of clinicopathologic correlation.
