Relationship of anti-SARS-CoV-2 IgG antibodies with Vitamin D and inflammatory markers in COVID-19 patients.

Several studies have found an association of COVID-19 disease severity with Vitamin D deficiency and higher levels of anti-SARS-CoV-2 IgGs. The aim of this study was to determine whether levels of Vitamin D and "inflammatory state" influence the magnitude of anti-SARS-CoV-2 IgGs levels in COVID-19 patients. For this purpose, in 67 patients levels of anti-SARS-CoV-2 IgG were measured in week 4 whereas in 52 patients levels of Vitamin D were measured in week 1 after symptom onset. We found that low Vitamin D levels were significantly associated with age and disease severity whereas there was a trend without significance, towards negative correlation of Vitamin D with anti-SARS-CoV-2 IgG. Anti-SARS-CoV-2 IgG were significantly higher in older ages, patients with severe disease, diabetes and those who received corticosteroid and antibiotic therapy. There was a positive correlation of anti-SARS-CoV-2 IgG with IL-6, CRP, LDH, ESR and with percentages of granulocytes. In conclusion, Vitamin D and anti-SARS-CoV-2 IgG share common parameters associated with inflammatory state. However, even though Vitamin D protects against severe forms of COVID-19 it could not directly affect anti-SARS-CoV-2 IgG production.

A Nonfatal Case of Dobrava Hantavirus Hemorrhagic Fever with Renal Syndrome Combined with Hantavirus Cardiopulmonary Syndrome.

Among hantaviruses (HTNV), 22 are known as pathogenic for humans. HTNV can cause two clinical entities: hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome or hantavirus cardiopulmonary syndrome (HCPS). In most countries of Eastern Europe as well as in Kosovo, HTNV infection is presented mainly as HFRS. Here, we report a 20-year-old man with HFRS and HCPS caused by Dobrava hantavirus strain, successfully treated in Intensive Care Unit of Infectious Diseases Clinic, University Clinical Center of Kosovo. In HFRS endemic areas, patients with acute respiratory distress syndrome need to be evaluated for Dobrava hantavirus strain as a possible causative agent.

Early neurologic complications and long-term sequelae of childhood bacterial meningitis in a limited-resource country (Kosovo).

PURPOSE: Since neurologic complications of childhood bacterial meningitis are encountered frequently despite antibiotic treatments, the purpose of this study was to analyze early neurologic complications and long-term sequelae of bacterial meningitis in children in a limited-resource country (Kosovo) METHODS: This study uses a retrospective chart review of children treated for bacterial meningitis in two study periods: 277 treated during years 1997-2002 and 77 children treated during years 2009-2010. RESULTS: Of the 277 vs 77 children treated for bacterial meningitis, 60 (22%) vs 33 (43%) patients developed early neurologic complications, while there were 15 (5.4%) vs 2 (2.6%) deaths. The most frequent early neurologic complications were the following: subdural effusions (13 vs 29%), recurrent seizures (11 vs 8%), and hydrocephalus (3 vs 3%). The relative risk (95% confidence interval) for neurologic complications was the highest in infants (3.56 (2.17-5.92) vs 2.69 (1.62-4.59)) and in cases caused by Haemophilus influenzae 1.94 (1.09-3.18) vs Streptococcus pneumoniae 2.57(1.26-4.47). Long-term sequelae were observed in 10 vs 12% of children, predominantly in infants. The most frequent long-term sequelae were late seizures 9 vs 1%, neuropsychological impairment 1 vs 5%, and deafness 1 vs 3%. CONCLUSIONS: In both study periods, the most frequent early neurologic complications of childhood bacterial meningitis were subdural effusions. Long-term sequelae were observed in 10% of children, with late seizures, neuropsychological impairment, and deafness being the most common one. Age prior to 12 months was risk factor for both early neurologic complications and long-term sequelae of bacterial meningitis in children.

Review of Crimean Congo hemorrhagic fever infection in Kosova in 2008 and 2009: prolonged viremias and virus detected in urine by PCR.

Crimean-Congo hemorrhagic fever (CCHF) is a virus transmitted predominantly by ticks. However, contact with infected body fluids or tissues can result in animal-to-human or human-to-human transmission. Numbers of CCHF cases appear to be increasing, especially in Europe. We reviewed cases admitted to a tertiary referral unit in Kosova with suspected CCHF in 2008 and 2009, and looked at a smaller number of specimens which were sent to the Health Protection Agency, Porton Down, U.K., in further detail. The clinical features of cases admitted with suspected CCHF infection were assessed in more detail, and these are the focus of this article. Between 2008 and 2009, the numbers of patients admitted for suspected CCHF infection increased. Of the samples received in Porton Down, CCHF virus was detected in urine samples, and these patients were found to have prolonged viremia. The detection of CCHF in urine, as well as the prolonged viremias seen, are important for clinicians to know, as they may have public health implications with regard to the risk of infection, as well as provide insights into the biology and pathophysiology of infection. Further studies are required regarding the pathogenesis of this virus.
