ABSTRACT

BACKGROUND: Pregnant women are vulnerable against COVID-19 infection due to physiological and immunological changes. COVID-19 in pregnancy affects fetal well-being with a potential for vertical infection. AIM: This study aims to determine the incidence of vertical infection and anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in infants born to mothers with positive COVID-19 infection. MATERIALS AND METHODS: Amniotic fluid, swabs of the newborn's nasopharynx and oropharynx, and swabs of the placenta were examined using reverse transcription polymerase chain reaction (RT-PCR) for SARS-CoV-2. Serological examination was performed by Electro-Chemiluminescence Immunoassay on infant's blood. RESULT(S): Four of 33 pregnant women gave birth to infants positive SARS-CoV-2 infection. RT-PCR examination of all amniotic fluid and placental swabs was negative for SARS-CoV-2. Four of 33 infants (12.1%) showed negative polymerase chain reaction (PCR) results but positive SARS-CoV-2 antibodies, another 4 newborns (12.1%) showed positive PCR results, but no SARS-CoV-2 antibodies detected. The remaining 25 babies (75.8%) showed both negative PCR and serologic results. CONCLUSION(S): No evidence of vertical transmission found in this study.Copyright © 2023 Cut Meurah Yeni, Zinatul Hayati, Sarjani M. Ali, Hasanuddin Hasanuddin, Rusnaidi Rusnaidi, Cut Rika Maharani.

ABSTRACT

Introduction and aim. The aim of this study is to evaluate the effects of topical lidocaine application for nasopharyngeal sampling, on pain perception, the comfort of the patients, and the application difficulty for healthcare staff. Material and methods. This study conducted with 100 healthy volunteers (50 participants in Lidocaine group and 50 participants in Placebo group). Two ml of a solution containing 10 mg/ml of lidocaine was applied to each nostril of the participants in the Lidocaine group, and the same dose of 0.9% NaCl to the Placebo group. We compared the changes in pain intensity and discomfort intensity using two numerical rating scales, the frequency of undesirable reactions, and the judgment of the practitioner staff. Results. There were statistically significant decreases in pain and discomfort scores in the Lidocaine group. Similarly, there were statistically significant decreases in the frequency of all undesirable reactions except "grimace”, in the second sampling in the Lidocaine group, however, there was a statistically significant decrease only in "holding staff's hand” in second sampling in the Placebo group. Conclusion. Intranasal lidocaine application reduces the pain that occurs during nasopharyngeal sampling and makes the procedure easier for the patient and the healthcare worker. © 2022 Publishing Office of the University of Rzeszow.

ABSTRACT

Background: Serum interleukin 6 (IL-6) levels have been studied in the diagnostic evaluation of patients with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) disease (COVID-19). Methods: We studied the utility of treatment with tocilizumab in COVID-19 patients (n=19) with a negative nasopharyngeal swab real time reverse transcriptase polymerase chain reaction (RT-PCR) test for SARS-CoV-2 who had suggestive computed tomography (CT) findings, namely, COVID-19 Reporting and Data System (CO-RADS) 4,5. Results: Receiver operator characteristic (ROC) curve analysis showed that serum IL 6 at a cut-off of >56.9 pg/L was a predictor of mortality in nasopharyngeal swab RT-PCR negative patients with suggestive CT findings. Tocilizumab had no significant effect on the mortality. Conclusions: In nasopharyngeal swab RT-PCR negative patients with suggestive chest CT findings, elevated serum IL-6 levels > 56.9 pg/L predicted mortality. However, treatment with tocilizumab had no effect on mortality.

ABSTRACT

Objective: To describe the clinical features, causal agent and transmission mode of a fever outbreak in a school in Shanghai. Methods: Field epidemiological approaches including case definition development, searching for contacts, distribution of diseases description, environmental sampling and laboratory testing. Results: A total of 16 influenza-like cases were included, all concentrated in the one class of grade two, including 15 students and 1 teacher. Among student cases, the incidence rate was 36.59%(15/41), the average age was 7.4 years, the incidence rate was 36.84%(7/19) for boys, 36.36%(8/22) for girls. The clinical course was 5-15 days, with the median of 9 days, and 18.75%(3/16) of the cases stayed studying while sick. The nasopharyngeal swab specimens in 16 cases all tested positive for influenza B, of which 11 tested positive for mycoplasma pneumoniae and 1 case also tested positive for coronavirus OC43. Body temperature, number of mononuclear cells, and treatment time of patients infected with Influenza B and mycoplasma pneumoniae were higher than those of patients infected with influenza B alone(P < 0.05). The outbreak lasted for 12 days, all sick students were treated and discharged from hospital, with no severe cases or death, and the outbreak was effectively controlled. Conclusion: This campus cluster outbreak caused by influenza B and mycoplasma pneumoniae. Patients with influenza B with mycoplasma pneumoniae have severe symptoms and a long course of illness, suggesting the importance of early management of the epidemic.

ABSTRACT

OBJECTIVES: We analyzed the expression of inflammatory and antiviral genes in the nasopharynx of SARS-CoV-2 infected patients and their association with the severity of COVID-19 pneumonia. METHODS: We conducted a cross-sectional study on 223 SARS-CoV-2 infected patients. Clinical data were collected from medical records, and nasopharyngeal samples were collected in the first 24 hours after admission to the emergency room. The gene expression of eight proinflammatory/antiviral genes (plasminogen activator urokinase receptor [PLAUR], interleukin [IL]-6, IL-8, interferon [IFN]-ß, IFN-stimulated gene 15 [ISG15], retinoic acid-inducible gene I [RIG-I], C-C motif ligand 5 [CCL5], and chemokine C-X-C motif ligand 10 [CXCL10]) were quantified by real-time polymerase chain reaction. Outcome variables were: (i) pneumonia; (ii) severe pneumonia or acute respiratory distress syndrome. Statistical analysis was performed using multivariate logistic regression analyses. RESULTS: We enrolled 84 mild, 88 moderate, and 51 severe/critical cases. High expression of PLAUR (adjusted odds ratio [aOR] = 1.25; P = 0.032, risk factor) and low expression of CXCL10 (aOR = 0.89; P = 0.048, protective factor) were associated with pneumonia. Furthermore, lower values of ISG15 (aOR = 0.88, P = 0.021), RIG-I (aOR = 0.87, P = 0.034), CCL5 (aOR = 0.73, P <0.001), and CXCL10 (aOR = 0.84, P = 0.002) were risk factors for severe pneumonia/acute respiratory distress syndrome. CONCLUSION: An unbalanced early innate immune response to SARS-CoV-2 in the nasopharynx, characterized by high expression of PLAUR and low expression of antiviral genes (ISG15 and RIG-I), and chemokines (CCL5 and CXCL10), was associated with COVID-19 severity.

ABSTRACT

Hypertension is the most common concomitant disease in COVID-19. Although the increased mortality from a new coronavirus infection occurring against the background of concomitant hypertension has been proven many times, the greater problem is the search for prognostic factors that would allow predicting the risk of severe infection caused by SARS-CoV-2 and death at an early stage. The aim of the study was to determine the level of some markers of acute inflammation (ferritin, C-reactive protein, IL-6) in patients with a new coronavirus infection combined with hypertension. Material and methods. The study included 130 patients of two groups: the main group - patients with COVID-19, occurring against the background of hypertension (n=70), the control group - patients with COVID-19 of moderate severity without concomitant diseases (n=60). Criteria for inclusion in the main group: the presence of stage II hypertension (drug-controlled) and the absence of additional concomitant diseases, including severe obesity >II degrees (body mass index >35 kg/m2). Patients of the main group by age (from 38 to 65 years, average age 57.0+/-6.9 years) did not differ from patients of the control group (from 42 to 65 years, average age 53.6+/-6.6 years). Women prevailed in both groups - 61.4% in the main group and 70% in the control group, respectively. The criteria for excluding patients were: BDD no more than 30/min, SpO2 no lower than 93%, absence of a positive result of a study on SARS-CoV-2 RNA by PCR from the nasopharynx and oropharynx, CT changes characteristic of a viral lesion involving more than 50% of lung parenchyma (CT 3-4), IL-6 levels over 40 pg/ml, age over 65 years. Results. The ferritin index above 500 ng/ml was in 30% of patients of the main and 23.3% of the control group. Comparison of ferritin levels in the two groups showed that its indicators in patients of the main group were significantly higher than those of the control group (p=0.033;p<0.05). C-reactive protein (CRP) was also more often elevated in patients of the main group with arterial hypertension than in patients without a history of hypertension (55.7+/-5.1 and 45.3+/-4.6 mg/l, respectively), but the difference in the degree of its increase was not significant (p=0.132;p>0.05). The average value of IL-6 in both groups was within normal values: 8.9+/-1.2 pg/ml in the main group and 5.6+/-1.1 pg/ml in the control group (p=0.045;p<0.05). Conclusion. In patients with COVID-19, which occurred against the background of hypertension, there was a significant increase in the level of a number of markers of acute inflammation (ferritin, IL-6) compared with patients without concomitant hypertension. These changes may be associated with the effect of high blood pressure on the vascular wall, as well as with the tropicity of the virus to vascular endothelial cells.Copyright © 2021 Moscow State University of Psychology and Education.

ABSTRACT

Objective: To represent the effects of the severity of COVID-19 infection on platelet large cell ratio (PLC-R). Materials and Methods: A hundred eleven patients diagnosed with COVID-19 were included in this study. Positive results for SARS-CoV-2 based on a typical RT-PCR test performed on nasopharyngeal swabs were included in the study Groups. Patients with COVID-19 were divided into three Groups according to their chest CT features. Group 1 (45 patients) was defined as mild, Group 2 (34 patients) as moderate and Group 3 (32 patients) as severe. Complete blood count parameters including platelet volume indices (PVI) values, CRP, D-dimer and lipid profiles were analyzed in all study participants. The correlation between COVID-19 patient Groups and PLC-R values were demonstrated using SPSS and ANFC methods. Results: The significant impact of our study is that PLC-R was significantly higher in the severe COVID-19 patients than the moderate and mild patients. Spearman's rho correlation analysis showed that PLC-R and WBC levels increased, and Htc and Hb levels decreased with the severity of the disease. ROC analysis showed that PLC-R > 38.3% had 59.4% sensitivity and 68.4% specificity in predicting severe COVID-19 disease (AUC 0.672, %95 CI 0.560, 0.784;p=0.005, cut off=38.3). CRP, ferritin and D-dimer values of the patients in Group 3 were significantly higher than the patients in Group 1, and the iron values of the patients in Group 3 were significantly lower than the patients in Group 1. Conclusion: PLC-R values are useful for anticipating acute thrombotic events. Based on the results of our study, PLC-R values can be used as appropriate biomarkers to describe the severity of COVID-19 infection.

ABSTRACT

Background: The currently approved vaccines do not induce sterilizing immunity against SAR-CoV-2 infection, and immunity wanes over time. A robust broad spectrum topical prophylaxis strategy could protect vulnerable populations in the face of continuous evolution of SARS-CoV-2. The algal antiviral lectin Griffithsin (GRFT), and an engineered oxidation-resistant variant Q-GRFT have robust entry inhibitory activity against SARS-CoV variants of concern, in addition to other respiratory viruses with pandemic potential. We designed a nasal spray to deliver Q-GRFT to the upper respiratory tract mucosa for on-demand use as a broad-spectrum prophylactic. Two clinical trials (Phase 1a and 1b) were conducted to assess safety, tolerability, and pharmacokinetics of Q-GRFT nasal spray in healthy adults. Method(s): Healthy adult volunteers were enrolled in a Phase 1a double blinded, randomized study to receive a single dose of either intranasal Q-GRFT (3.0 mg, 2 sprays per nostril) or placebo at 2:1 ratio. Following a safety review, the Phase 1b study was initiated. Eleven volunteers in Group 1 received 3.0 mg dose once daily, for 7 days. After a safety review, 11 volunteers in Group 2 received a total of 6.0 mg Q-GRFT (3.0 mg twice daily for 7 days). Topical Q-GRFT concentrations were measured by ELISA in collected nasal and nasopharyngeal fluids. Drug levels in plasma were assayed to determine systemic exposure. Viral microneutralization cytopathic effect (CPE) assays were performed against SARS-CoV-2 Omicron BA-5 and MERS-CoV. Result(s): Eighteen adults (24-54 years;Males 58.3%, Females 41.7%;12 Q-GRFT, 6 Placebo), and 22 adults (aged 23-59 years;Males 52.4%, Females 47.6%) were enrolled in Phase 1a and 1b, respectively. In Phase 1a, a single dose of Q-GRFT maintained quantifiable levels in nasal passages and nasopharynx for up to 24 hours. Similarly, Q-GRFT was quantifiable in nasal and nasopharyngeal regions in the Phase 1b study. No dose accumulation effect or systemic exposure was observed. Nasal and nasopharyngeal swab eluates inhibited SARS-CoV-2 Omicron BA.5 and MERS-CoV in CPE assays. Q-GRFT did not modify olfactory sensation. No severe adverse events were reported. Thus, the nasal spray was deemed safe. Conclusion(s): Intranasal Q-GRFT was safe and enhanced mucosal SARSCoV-2 inhibitory activity in human volunteers. The results support further development of Q-GRFT as a broad-spectrum prophylactic against coronaviruses to curb ongoing infections, and for future pandemic preparedness.

ABSTRACT

Objectives: Various reagents and equipment for testing SARS-CoV-2 infections have been developed, particularly rapid molecular tests based on polymerase chain reaction (PCR). Methods: We evaluated the analytical performance of four rapid molecular tests for SARS-CoV-2. We used 56 nasopharyngeal swabs from patients with confirmed SARS-CoV-2 infection;36 diagnosed as positive by the AmpdirectTM 2019-nCoV Detection Kit (Shimadzu assay) were considered as true-positive samples. Results: The sensitivity of CobasR Liat SARS-CoV-2 and Flu A/B (Cobas) was the highest among the four molecular test kits. The limit of detection was 1.49 x 10-2 copies/ micro L (95% confidence interval [CI]: 1.46x10-2-1.51 x 10-2 copies/ micro L) for Cobas;1.43 x 10-1 copies/ micro L (95% CI: 8.01x10-3-2.78 x 10-1 copies/ micro L) for XpertR Xpress SARS-CoV-2 test (Xpert);2.00 x 10-1 copies/ micro L (95% CI: 1.95x10-1-2.05 x 10-1 copies/ micro L) for FilmArray Respiratory Panel v2.1 (FilmArray);and 3.33 x 10 copies/ micro L (95% CI: 1.93 x 10-4.72x10 copies/ micro L) for Smart GeneR SARS-CoV-2 (Smart gene). Cobas also had a high sensitivity (100%) compared with Shimadzu assay. The sensitivities of Xpert, FilmArray, and Smart Gene were 97.2%, 97.2%, and 75.0%, respectively. The specificity of all tests was 100%. Conclusions: In conclusion, the four rapid SARS-CoV-2 molecular test kits have high specificity and sensitivity for detecting SARS-CoV-2. As they are easy to use, they could be a useful method for detecting SARS-CoV-2.

ABSTRACT

Background: SARS-CoV-2 variants resistant to monoclonal antibodies, and drug-drug interactions and potential mutagenicity of direct acting antivirals, heightens the need for additional therapeutics to prevent progression to severe COVID-19. Exogenous interferon beta is a promising therapeutic option against SARS-CoV-2 given its broad-spectrum antiviral activity and data suggesting impaired endogenous IFN production in individuals with severe disease. Method(s): The safety and efficacy of orally inhaled nebulized interferon-beta1a (SNG001) was evaluated in a Phase II randomized controlled trial on the ACTIV-2/ A5401 platform (NCT04518410). Adult outpatients with confirmed SARS-CoV-2 infection within 10 days of symptom onset were randomized to SNG001 once daily for 14 days or blinded pooled placebo. Primary outcomes included treatment-emergent Grade >=3 adverse event (TEAE) through day 28;time to symptom improvement of 13 targeted COVID-19 symptoms collected by daily study diary through day 28;and SARS-CoV-2 RNA < lower limit of quantification (LLoQ) from nasopharyngeal (NP) swabs at days 3, 7, and 14. All-cause hospitalization or death through day 28 was a key secondary outcome. Result(s): Of 221 participants enrolled at 25 US sites between February and August 2021, 220 (110 SNG001, 110 placebo) initiated study intervention, with a median age of 40 years, 55% female, and 20% SARS-CoV-2 vaccinated. There was no significant difference between SNG001 and placebo in Grade >=3 TEAEs (4% vs 8%, Fisher's exact test p=0.25). Median time to symptom improvement was 13 days for SNG001 and 9 days for placebo (Gehan-Wilcoxon test p=0.17). There was no difference in the proportion of participants with SARS-CoV-2 RNA < LLoQ at day 3, 7 or 14 (SNG001 vs placebo, Day 3: 28% vs. 39%;Day 7: 65% vs. 66%;Day 10: 91% vs. 91%;joint Wald test p=0.41). There were fewer hospitalizations with SNG001 (n=1;1%) compared with placebo (n=7;6%), but this difference was not statistically significant (Fisher's exact test p=0.07;Figure). All hospitalizations were due to COVID-19 and occurred among unvaccinated participants without protocol-defined high-risk factors. Conclusion(s): Inhaled nebulized SNG001 was safe and well tolerated but did not reduce SARS-CoV-2 RNA levels in the nasopharynx nor decrease time to improvement of COVID-19 symptoms in outpatients with mild-to-moderate COVID-19. The non-statistically significant decrease in hospitalizations among SNG001 participants warrants further investigation in a phase 3 clinical trial. Cumulative incidence of hospitalization or death comparing SNG001 vs. placebo.

ABSTRACT

Objective To analyze the epidemiological characteristics of respiratory syncytial virus(RSV) before and after the COVID-19 epidemic in Guangzhou in recent years. Methods Nasopharynx swabs from hospitalized patients with acute respiratory infection were collected from two sentinel hospitals in Guangzhou(Guangdong Maternal and Child Health Hospital and Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University) from 2018 to 2022. Luminex respiratory multi-pathogen detection technology was used to detect and type RSV in samples. Results A total of 1 243 nasopharyngeal swab samples were collected. The overall positive rate of RSV was 6. 11%(76/1 243), including 39 RSV-A(51. 32%, 39/76) and 37 RSV-B(48. 68%, 37/76). The highest detection rate of RSV in children under 3 years old was 8. 79%(66 cases). Compared with 2018(8. 30%, 22/265) and 2020(14. 78%, 30/203), the positive rate of RSV decreased significantly in 2019(3. 13%, 10/319), 2021(4. 08%, 10/245) and 2022(1. 90%, 4/211). Compared with 2018(8. 30%,22/265) and 2020(14. 78%,30/203),the positive rate of RSV decreased significantly in 2019(3. 13%,10/319), 2021(4. 08%,10/245) and 2022(1. 90%,4/211). Type A prevailed in 2018(19/22) and 2022(4/4), type B(25/30) prevailed in 2020, type A and type B coexisted in 2019 and 2021. The detection rate showed had no statistically significant seasonal difference except for 2020 [7. 14%(3/42), 16. 39%(10/61), 27. 12%(16/59), 0(0/42),χ~2= 16. 975,P<0. 001]. Among all the 76 RSV positive samples, 17(22. 37%) showed multiple infections. Among them, human rhinovirus was the most common virus causing mixed infection, accounting for 58. 83%(10/17) of the mixed infection. Conclusion RSV is a common respiratory virus prevalent in Guangzhou, and children under 3 years old are the main population infected with RSV. RSV infection is prevalent every other year, with the characteristics of alternating epidemic of type A and type B, and the anti-seasonal epidemic appeared after the COVID-19. After the outbreak of COVID-19, the detection rate of RSV increased significantly in 2020. With the change of the national COVID-19 epidemic prevention and control policy, the detection rate of RSV declined significantly during 2021-2022.

ABSTRACT

Objective: To analyze the viral shedding time and its influencing factors in different site samples of patients infected with severe acute respiratory syndrome coronavirus 2 (SARA-CoV-2) omicron BA.2 variant. Methods: Real-time fluorescence polymerase chain reaction was used to detect SARS-CoV-2 nucleic acid in nasopharyngeal swab, sputum and anal swab from 217 patients with coronavirus disease 2019 (COVID-19) who were infected with severe acute respiratory syndrome coronavirus 2 omicron BA.2 variant confirmed by gene sequencing in The First Affiliated Hospital of Naval Medical University (Second Military Medical University). The differences of viral shedding time of different site samples were compared. Stratified analysis and multiple linear regression analysis were used to explore the influencing factors of viral shedding time in different site samples. Results: The age of the 217 COVID-19 patients was 32.0 (24.0, 50.5) years old, 59.0% of them were males (n=128), and 41.0% were females (n=89). Eight (3.7%) cases were diagnosed with asymptomatic infection, 184 (84.8%) cases were mild type, 21 (9.7%) cases were moderate type, 3 (1.4%) cases were severe type, and 1 (0.5%) case was critical type. A total of 70 (32.3%) patients were treated with molnupiravir. The viral shedding time of SARS-CoV-2 nucleic acid in nasopharyngeal swab, sputum and anal swab was 13.0 (11.0, 17.0) d, 16.5 (13.0, 21.0) d and 10.0 (5.3, 11.0) d, respectively, with the differences being significant between them (all P<0.001). Age 60 years old, underlying diseases (especially hypertension, coronary artery diseases, or neurological diseases), and clinical classification of moderate type were risk factors for prolonged viral shedding time in nasopharyngeal swab;male sex and underlying diseases were risk factors for prolonged viral shedding time in sputum;and male sex was a risk factor for prolonged viral shedding time in anal swab. Multiple linear regression analysis showed that critical type was an independent risk factor for prolonged viral shedding time in nasopharyngeal swab (P<0.05), and male sex and underlying diseases were independent risk factors for prolonged viral shedding time in sputum (both P<0.05). Conclusion: Among patients infected with omicron BA.2 variant, the viral shedding time in sputum is the longest and that in anal swab is the shortest. Male patients and/or patients with underlying diseases have longer viral shedding time in sputum.

ABSTRACT

Clinical parameters characterizing the efficacy and safety of favipiravir were examined in a multicenter, non-interventional (before-and-after study design) trial in 264 patients with mild COVID-19. It is shown that on the background of 14-day therapy with favipiravir body temperature normalized, blood oxygen saturation improved, and the frequency of tachycardia detection reduced by 16% (p < 0.0001). A statistically significant decrease by 91,3% (p 0.0001) in the frequency of SARS-nCoV-2 RNA detection in the nasopharyngeal mucosa discharge was revealed. A decrease in the concentration of ferritin (by 69% compared to initial values), blood glucose (by 21%), creatinine (by 10%), C-reactive protein (by 36%) (p 0.0001), and D-dimer by 61% (p = 0.016) was noted. The results of the SF-36 health survey questionnaire revealed a significant (p 0.05) improvement in the quality of life in terms of physical functioning (by 35%), and role functioning associated with physical and emotional state by 107% and 160%, respectively. Analysis of the COV19-QoL questionnaire revealed a decrease by 24% in negative perception of the disease (p < 0,01). Among the identified adverse events, elevated level of ALT (in 39.47% of patients), hyperuricemia (in 28.95% of patients), and elevated AST (in 23.68% of patients) prevailed. All the adverse events occurred with mild or moderate severity. There were no lethal outcomes in the studied sample of patients. The analysis showed a satisfactory level of the tolerability of the treatment.Copyright © 2023 Izdatel'stvo Meditsina. All rights reserved.

ABSTRACT

Background: A variety of skin conditions are reported in association with COVID-19. Among these clinical patterns, urticarial lesions are described. We present a case of new-onset urticaria in an adult patient with mild COVID-19. In addition, we performed a comprehensive structured literature search to evaluate the temporal relationship between COVID-19 and urticarial manifestations and their duration. Method(s): This case report presents an adult patient with new-onset urticaria and confirmed diagnosis of COVID-19, assessed according to international guidelines. A systematic review was conducted for relevant studies published in Pubmed/Medline database, between January 2020 and January 2022, using specific keywords for clinical and temporal features of skin lesions. Result(s): A 28-year- old male with a 24-hour history of fever and headache presented new-onset urticarial lesions. In the context of COVID-19 pandemic, infection with SARS-CoV- 2 was suspected, and a PCR test detected viral RNA in a nasopharynx sample confirming the diagnosis in this patient. Other clinical manifestations and abnormal laboratory findings were not detected. A diagnosis of SARS-CoV- 2 infection-associated urticaria was established. The urticarial rash improved with oral new-generation H1 antihistamines and was remitted in 5 days. The outpatient treatment did not include systemic corticosteroid and antiviral therapy. Out of 3542 articles published in PubMed on cutaneous manifestations linked to COVID-19/ SARS-CoV- 2 infection, 53 met the criteria of assessing urticaria in these conditions. From these, 30 were case reports, 13 were case series and 10 were cohort studies. From 273 patients reported with urticaria, only 53 had a clear mention of a positive antigen or nucleic acid amplification viral test. Urticaria preceded the onset of respiratory/systemic COVID-19 symptoms in 12 patients, appeared at the same time in 81 patients, and as a late manifestation in 45 patients. For 135 patients, the timing was not specified. Urticarial lesions were remitted between several hours to 12 weeks, either spontaneously or with symptomatic treatment. Conclusion(s): Based on reported cases, urticaria may be associated with COVID-19. There is a need for more relevant studies regarding urticaria in these infectious conditions, with detailed data on clinical pattern, time of onset, duration, severity, need for specific treatment and prognosis.

ABSTRACT

Background: The COVID-19 pandemic has led to a dramatic loss of human life worldwide and presents an unprecedented challenge for healthcare systems worldwide. Earlier to SARS-CoV pandemic, coronaviruses were only thought to cause mild, self-limiting upper respiratory tract infections in humans. COVID 19 presents across a spectrum of symptoms. WHO recommends detection of unique sequences of virus RNA by Nucleic Acid Amplification Test (NAAT) such as real-time reverse-transcriptase polymerase chain reaction (rRT-PCR). The aim of this cross sectional study was analysis and confirmation of Nasopharyngeal/oropharyngeal swab specimen by real-time reverse transcription polymerase chain reaction (RT-PCR). Material & Methods: This was a cross-sectional retrospective study that reviewed records of samples collected from June 2021 to March 2022. Nasopharyngeal/oropharyngeal swab specimen were collected from suspected COVID-19 subjects of various districts of Punjab and referred to Viral Research Diagnostic Laboratory [VRDL], Government Medical College [GMC], Amritsar for laboratory analysis and confirmation by real-time reverse transcription polymerase chain reaction (RT-PCR). Results: During the present study, a total of 11,27,005 samples were analyzed from June 2021 to March 2022 for SARS-CoV-2 detection by ICMR approved COVID-19 RT-PCR kits. Out of total 11,27,005 cases, 24,466 cases (2.17%) were found to be SARS-CoV-2 positive while 11,02,539 cases (97.83%) were SARS-CoV-2 negative. Conclusions: Ever since the COVID-19 global pandemic emerged, the developing countries are facing challenges regarding its diagnosis. Isolation of the infected person will eventually decrease the Reproduction number i.e Ro which will further interrupt the transmission cycle leading to decrease in community spread.

ABSTRACT

Histoplasmosis is a rare type of fungal infection which may manifest as a respiratory disease or as a disseminated infection. It is common in immunocompromised patients and, in recent times, seen in association with COVID-19. On histopathological examination, many intracellular and extracellular yeast forms are seen, which can be confirmed by fungal stains. Histoplasmosis involving the nasopharyngeal region is quite rare. Till date, only less than 100 cases of pharyngo-laryngeal histoplasmosis have been reported. Such cases are clinico-radiologically easily and frequently mistaken for malignancy. Here, we report a case that initially had COVID-19-like symptoms and later presented with a nasopharyngeal mass clinico-radiologically mistaken as a nasopharyngeal malignancy. The diagnosis was established on histopathological examination and the patient recovered completely with anti-fungal treatment. A high grade of suspicion and thorough histopathological examination, especially in immunocompromised patients, complimented by fungal special stains is quite rewarding as even a disseminated disease is curable.

ABSTRACT

Background & Objectives: This study aimed to compare PD patients with and without COVID-19 and to evaluate the associated factors about prognosis. Methods: The data of 37 hospitalized PD patients associated with COVID-19 pneumonia were evaluated. It was compared with the data of 40 PD patients who did not have COVID-19 in the same period. Clinical findings, prognosis, mortality and other related factors were compared in PD patients with and without COVID-19. Results: Hypertension was higher comorbid disease in PD patients with COVID-19 (p = 0.005). The duration of PD was longer in patients without COVID-19 disease (6.02 ± 2.80 vs 5.08 ± 4.59) (p = 0.028). In PD patients with COVID-19, the most common symptoms were myalgia-arthralgia (73.0%) and fatigue (48.6%). Intensive care was required in 17 (45.9%) patients, and invasive mechanical ventilation (IMV) was required in 9 (24.3%) patients. The in-hospital mortality rate was 29.7% (n = 11). Mortality and IMV requirement were higher in patients whose initial symptom was diarrhea (p = 0.004, p = 0.008, respectively). No correlation was detected between PD stage, treatment options and prognosis (p < 0.05). Conclusion: Mortality rate and IMV requirement are higher in PD patients with COVID-19 pneumonia, particularly in patients with initial symptoms of diarrhea. These patients should be followed more carefully in terms of probable poor prognosis. © 2023, ASEAN Neurological Association. All rights reserved.

ABSTRACT

Background: Nasal swabs and saliva samples are being considered alternatives to nasopharyngeal swabs (NPSs) for detecting severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2); however, few studies have compared the usefulness of nasal swabs, NPSs, and saliva samples for detecting SARS-CoV-2 and other respiratory virus infections. We compared the positivity rates and concentrations of viruses detected in nasal swabs, NPSs, and saliva samples using cycle threshold (Ct) values from real-time PCR tests for respiratory viruses. Methods: In total, 236 samples (48 five-rub and 10 10-rub nasal swabs, 96 NPSs collected using two different products, 48 saliva swabs, and 34 undiluted saliva samples) from 48 patients (34 patients with SARS-CoV-2 and 14 with other respiratory virus infections) and 40 samples from eight healthy controls were obtained. The PCR positivity and Ct values were compared using Allplex Respiratory Panels 1/2/3 and Allplex SARS-CoV-2 real-time PCR. Results: NPSs showed the lowest Ct values (indicating the highest virus concentrations); however, nasal and saliva samples yielded positive results for SARS-CoV-2 and other respiratory viruses. The median Ct value for SARS-CoV-2 E gene PCR using nasal swab samples collected with 10 rubs was significantly different from that obtained using nasal swabs collected with five rubs (Ct=24.3 vs. 28.9; P=0.002), but not from that obtained using NPSs. Conclusions: Our results confirm that the NPS is the best sample type for detecting respiratory viruses, but nasal swabs and saliva samples can be alternatives to NPSs. Vigorously and sufficiently rubbed nasal swabs can provide SARS-CoV-2 concentrations similar to those obtained with NPSs.
