Severe pneumonia caused by Legionella pneumophila detected by a multiplex polymerase chain reaction assay and confirmed by serology

Legionella pneumophila is a rarely diagnosed microorganism in Serbia. It causes legionellosis, usually a mild respiratory infection. However, in some cases it can be severe and even life threatening. In June 2020, during the COVID-19 pandemic, a patient with symptoms of the aforesaid infection, namely severe pneumonia and acute respiratory distress syndrome, was admitted to the hospital. The multiplex polymerase chain reaction (PCR) test (The BioFire FilmArray Pneumonia Panel plus) detected the presence of L. pneumophila in the patient's bronchial secretions. The specific culture for the detection of that organism, however, remained sterile. The patient's paired sera had been sent for serology and the results in both of them came back positive for Legionella spp. 1–6, while the assays specific for each one of the 10 serogroups detected more than a fourfold increase of antibody titers in an uncommon serogroup 2 only. The patient was treated with moxifloxacin;he recovered well and was discharged after 26 days of hospitalization. Having being diagnosed with the L. pneumophila infection correctly through the multiplex PCR test, the patient was given the right therapy with moxifloxacin. The serologic assays corroborated this result and revealed the uncommon group 2, thus confirming the necessity of carrying out all the tests available to attain the exact diagnosis of legionellosis.

Canagliflozin Markedly Decreased Proteinuria in a Patient With IgA Nephropathy.

IgA nephropathy (IgAN) remains one of the most common forms of glomerulonephritis, especially in developed countries with a low prevalence of infectious diseases. Despite supportive measures that slow the rate of progression of chronic kidney disease (CKD) in IgAN, many patients still progress to end-stage kidney disease. Proteinuria has been shown to be an adverse prognostic factor in IgAN. Data support the use of proteinuria reduction as a reasonably likely surrogate endpoint for a treatment's effect on progression to end-stage renal disease (ESRD) in IgAN. Currently employed immunosuppressive strategies lack conclusive efficacy data, while there is evidence for treatment-induced toxicity. The current standard of care for the management of IgAN is intensive goal-directed supportive care. Recently the role of sodium-glucose cotransporter 2 (SGLT2) inhibitors in decreasing proteinuria and progression of CKD is widely being recognized. In this case report, we present a 44-year-old male with proteinuria and biopsy-proven IgAN who remained in remission after six months of steroids using the Pozzi protocol. He developed proteinuria five years after remission. At this point, canagliflozin was added to his angiotensin-receptor blocker (ARB) therapy resulting in a significant reduction in his proteinuria. Our case report may intrigue researchers to look into the role of canagliflozin in decreasing albuminuria in non-diabetic kidney disease, thus slowing the progression to ESRD.

Dental care during the Covid-19 pandemic - To treat or not to treat?

The recent spread of COVID-19 presents a huge public health concern. Clinical presentations of COVID-19 range from asymptomatic cases to severe pneumonia that can lead to death. Drastic measures were necessary to prevent the disease from spreading and protect the most vulnerable groups in the general population. The rapid reorganization of the healthcare system and great efforts made by medical staff were needed to admit to hospitals and then treat a progressively growing number of patients. The predominant route of virus transmission is through direct contact with an infected individual or respiratory droplets, therefore, all dental procedures with aerosol-formation pose an extremely high risk for the spread of infection. The aim of this article is to provide an overview of the current epidemiological situation, routes of transmission, and specific recommendations for dental practices including patient screening and triage, infection control, and treatment protocols. In this situation, it is essential that all dental healthcare workers make wise clinical decisions and educate themselves and their patients on how to prevent the spread of infection.
