Objective: To determine the diagnostic accuracy of the Lactate Dehydrogenase, C-Reactive Protein and Ferritin in suspected patients of COVID-19. Study Design: Cross-sectional validation study. Place and Duration of Study: Pathology department of Combined Military Hospital Lahore in the month of May 2020. Methodology: We included 101 adult (>18 years) symptomatic suspected COVID-19 patients of both genders. Children, pregnant women and asymptomatic patients were excluded from study. Age, gender and results of Reverse Transcriptase Polymerase Chain Reaction, Lactate Dehydrogenase, C-Reactive Protein, ferritin were recorded. Results: Lactate Dehydrodenase had highest sensitivity (75%) with positive predictive value of 71.6% and diagnostic accuracy of 65.3% among three biochemical parameters studied. Receiver Operator Characteristic curve was studied. Area under curve of Lactate Dehydrogenase (AUC=0.65) and Ferritin (AUC=0.59) reflected their ability to prognosticate the presence of COVID19 disease. However, C-Reactive Protein (AUC=0.42) appeared to be a poor predictor of the disease. Conclusion: Raised serum Lactate Dehydrogenase (>490 U/L) and Ferritin (>152 ng/L) levels can be used to predict the Reverse Transcriptase Polymerase Chain Reaction positivity for COVID-19 in the population of suspected patients of COVID19. However, C-Reactive Protein is a poor predictor of COVID-19.

Subject: At the end of December 2019, a COVID-19 outbreak was reported for the first time in Wuhan, China. Which quickly expanded throughout China, then to 209 nations across America, Europe, Australia, and Asia. More than 50,000 people have died and over one million individuals have been afflicted worldwide, with the number fast rising. COVID-19 has been combated in various ways around the world. The gold standard for COVID-19 diagnosis is real-time fluorescence quantitative reverse transcriptase polymerase chain reaction (reverse transcriptase-polymerase chain reaction, RT-PCR) and viral gene sequencing. Currently, nasopharyngeal swabs from the upper respiratory tract are the most commonly employed nucleic acid detection samples. Objective of the Study: To estimate the level of ficolin in covid-19 patient in moderate and severe disease stage determination (series measurement and follow up) and find the diagnostic tool to early detect the virus to minimize the severity of the disease and further complication. Correlation of serum L-ficolin concentrations with Serum C-Reactive Protein, D-Dimer and Ferritin also to find Prognostic value of L-ficolin will be studied by corelating the treatment outcomes over one month with the three initial L-ficolin level. Materials and Methods: Sixty-two patients will be involved in the study from both sex male and female and different age group (18-80 yr.), the basal level of ficolin will be measure at time of admission of patient (time zero), then further serial measurement will be done on day 7 of admission for precise ficolin monitoring. Results: This study shows elevation of serum L-Ficolin level in survival and non-survival group. Conclusion: The results showed significant negative correlation between L-ficolin levels with the duration of illness (r = -0.377, p =0.020), however there were no significant correlation between L-ficolin levels with other patient‟s parameters.

Objectives. The study aims to describe characteristics and clinical outcome of patients with SARS-CoV-2 infection that received siltuximab according to a protocol that aimed to early block the activity of IL-6 to avoid the progression of the inflammatory flare. Patients and methods. Retrospective review of the first 31 patients with SARS-CoV-2 treated with siltuximab, in Hospital Clinic of Barcelona or Hospital Universitario Salamanca, from March to April 2020 with positive polymerase-chain reaction (PCR) from a nasopharyngeal swab. Results. The cohort included 31 cases that received siltuximab with a median (IQR) age of 62 (56-71) and 71% were males. The most frequent comorbidity was hypertension (48%). The median dose of siltuximab was 800 mg ranging between 785 and 900 mg. 7 patients received siltuximab as a salvage therapy after one dose of tocilizumab. At the end of the study, a total of 26 (83.9) patients had been discharged alive and the mortality rate was 16.1% but only 1 out of 24 that received siltuximab as a first line option (4%). Conclusions. Siltuximab is a well-tolerated alternative to tocilizumab when administered as a first line option in patients with COVID-19 pneumonia within the first 10 days from symptoms onset and high C-reactive protein.

AbstractIntroductionCOVID 19 is still a challenge in pediatrics due to variety of symptoms and different presentationsAimTo describe clinical, laboratorial and treatment of confirmed COVID-19 pediatric admitted in hospitals.MethodsA retrospective study was conducted in children (0-18 years), admitted between March and November 15, 2020, with confirmed COVID-19 by reverse transcription polymerase chain reaction or serological tests. Clinical data about symptoms, laboratorial exams and treatments were analysed. Patients were evaluated according predominant (PRS) or non-predominant respiratory symptoms (non-PRS)ResultsSixty-four patients were evaluated, being the median age 5.6 years. Forty-seven (73.4%) children were admitted with PRS and 17 (26.4%) with non-PRS. The main symptoms in the PRS group were fever in 74.5% of children and cough in 66%; and fever in 76.5% and edema/cavitary effusion in 29.4% in the non-PRS group. The median of C-reactive protein (in mg/dl) was 2.5 in the PRS group and 6.1 in the non-PRS group. Antibiotics were used in 85.1% of the PRS group and 94.1% of non-group. Comorbidity was present in 30/47 (63.8%) of PRS group and 8/17 (47.1%) of non-PRS group (p=0.22). Length of stay until 7 days in patients with comorbidity was present in 27/64 (42.1%) and more than 7 days in 11/64 (17.1%) (p= 0.2)ConclusionNon-PRS represented more than one quarter of admitted patients. Fever was the main symptom detected, elevated CRP was frequent and antibiotics were commonly prescribed. Comorbidity was found in both groups and his presence was not associated with a longer length of stay.

AbstractDue to the efforts to control schistosomiasis transmission in tropical countries, a large proportion of individuals from endemic areas present low parasite loads, which hinders diagnosis of intestinal schistosomiasis by the Kato-Katz (KK) method. Therefore, the development of more sensitive diagnostic methods is essential for efficient control measures. The aim was to evaluate the accuracy of a real-time polymerase chain reaction (RT-PCR) to detect Schistosoma mansoni DNA in fecal samples of individuals with low parasite loads. A cross-sectional population-based study was conducted in a rural community (n = 257) in Brazil. POC-CCA® was performed in urine and feces were used for RT-PCR. In addition, fecal exams were completed by 18 KK slides, saline gradient and Helmintex techniques. The combined results of the three parasitological tests detected schistosome eggs in 118 participants (45.9%) and composed the consolidated reference standard (CRS). By RT-PCR, 117 out of 215 tested samples were positive, showing 91.4% sensitivity, 80.2% specificity and good concordance with the CRS (kappa = 0.71). RT-PCR identified 86.9% of the individuals eliminating less than 12 eggs/g of feces, demonstrating much better performance than POC-CCA® (50.8%). Our results showed that RT-PCR is a valuable alternative for the diagnosis of intestinal schistosomiasis in individuals with very low parasite loads.

Objectives Although Trichomonas vaginalis (TV) has a low profile in urban Australia, local data has estimated the prevalence in women to be 10 times higher when using polymerase chain reaction (PCR) versus wet mount microscopy (4.8% v. 0.4%). Our aim was to determine the prevalence of TV in Sydney women using both wet mount and PCR. Methods: A cross-sectional study was conducted of women requiring sexually transmissible infection screening at the Sydney Sexual Health Centre. Vaginal swabs were examined for TV using PCR and wet mount microscopy. Results: In total, 781 of 1263 eligible women were tested; 3 out of 781 tested positive by PCR and 1 out of 781 by wet mount, giving a prevalence of 0.38% (95% confidence interval (CI): 0.14–1.12%) and 0.13% (95% CI: 0.03–0.71%) respectively. There was not enough power to compare PCR and wet mount. Conclusions: The results of this analysis indicate that in our female urban population, TV is a very rare sexually transmissible infection,with 0.38% prevalence, and routine screening by PCR is not indicated.

causes human intestinal cyclosporiasis. It is more common in the immunocompromised patients and mainly seen in people living with HIV/AIDS (PLHA), post-renal transplant (PRT) patients and immunocompromised children (IC). Diagnostic microscopy for the oocysts of the parasite is less sensitive, requiring examination of multiple stool samples. Here we developed a new single run polymerase chain reaction (PCR) assay for the detection of and it was used to know the hospital based prevalence of cyclosporiasis. A cross-sectional study was conducted from June 2016 to October 2020 in a tertiary care teaching hospital. A new single run amplification PCR-based diagnostic assay was developed for . Stool samples were collected from 121 PLHA, 135 PRT and 79 immunocompromised children (IC) other than PLHA and PRT. All stool samples were examined for the presence of oocysts as well as tested with new PCR assay. Modified Ziehl-Neelsen staining of the concentrated stool smear did not reveal oocysts of species in any stool specimen. However, new PCR assay detected in 2 stool specimens – one from a PLHA patient and another from a PRT patient, giving a prevalence of 0.6% (2/335), 0.8% (1/121) in PLHA and 0.7% (1/135) in PRT. It was not detected in IC. Cyclosporiasis is infrequent in southern part of India. The new single run PCR assay developed by us is simple and cost effective molecular assay for the detection of .

A 13-year-old girl exhibited rapid deterioration in mental status 15 days after surgery for craniopharyngioma. Serial CT scanning detected progression of a low-density lesion on the left frontotemporal lobe. The serum level of C-reactive protein was elevated and polymerase chain reaction identified herpes simplex virus DNA in the cerebrospinal fluid. Antiviral therapy with high-dose acyclovir (10 mg/kg 3 times daily) was begun. She recovered and could speak short sentences, but dysphasia and right hemiparesis remained. Early diagnosis and active treatment of herpes simplex encephalitis is essential for improving prognosis and saving lives.
