A short therapeutic regimen based on hydroxychloroquine plus azithromycin for the treatment of COVID-19 in patients with non-severe disease. A strategy associated with a reduction in hospital admissions and complications.

The new SARS-CoV-2 infection named COVID-19 has severely hit our Health System. At the time of writing this paper no medical therapy is officially recommended or has shown results in improving the outcomes in COVID-19 patients. With the aim of diminishing the impact in Hospital admissions and reducing the number of medical complications, we implemented a strategy based on a Hospital Home-Care Unit (HHCU) using an easy-to-use treatment based on an oral administration regimen outside the hospital with hydroxychloroquine (HCQ) plus azithromycin (AZM) for a short period of 5 days. Patients and methodsPatients [≥] 18 years old visiting the emergency room at the Hospital Universitario San Pedro de Logrono (La Rioja) between March, 31st and April, 12th diagnosed with COVID-19 with confirmed SARS-CoV-2 infection by a specific PCR, as follows: Patients with pneumonia (CURB [≤] 1) who did not present severe comorbidities and had no processes that contraindicated this therapeutic regime. Olygosimptomatic patients without pneumonia aged [≥] 55 years. Patients [≥] 18 years old without pneumonia with significant comorbidities. We excluded patients with known allergies to some of the antimicrobials used and patients treated with other drugs that increase the QTc or with QTc >450msc. The therapeutic regime was: HCQ 400 mg every twice in a loading dose followed by 200 mg twice for 5 days, plus AZM 500 mg on the first day followed by 250 mg daily for 5 days. A daily telephone follow-up was carried out from the hospital by the same physician. The end-points of our study were: 1.- To measure the need for hospital admission within 15 days after the start of treatment. 2.- To measure the need to be admitted to the intensive care unit (ICU) within 15 days after the start of the treatment. 3.- To describe the severity of the clinical complications developed. 4.- To measure the mortality within 30 days after starting treatment (differentiating if the cause is COVID-19 or something else). 5.-To describe the safety and adverse effects of the therapeutic regime. ResultsDuring the 13 days studied a total of 502 patients were attended in the emergency room due to COVID-19. Forty-two were sent at home; 80 were attended by the HHCU (patients on this study) and 380 were admitted to the Hospital. In our series there were a group of 69 (85.18%) patients diagnosed with pneumonia (37 males and 32 females). Most of them, 57 (82.60%) had a CURB65 score of <1 (average age 49) and 12 (17.40%) a CURB score of 1 (average age 63). Eighteen (22.50%) of the pneumonia patients also had some morbidity as a risk factor. 11 patients (13.75%) without pneumonia were admitted to the HHCU because comorbidities or age [≥] 55 years. Six patients with pneumonia had to be hospitalized during the observation period, 3 of them because side effects and 3 because of worsening. One of these patients, with morbid obesity and asthma, had clinical worsening needing mechanical ventilation at ICU and developed acute distress respiratory syndrome. With the exception of the patient admitted to the ICU, the rest of the patients were discharged at home in the following 8 days (3 to 8 days). Twelve patients (15%), 11 of whom had pneumonia, experienced side effects affecting mainly the digestive. In another patient a QTc interval prolongation (452 msc) was observed. In total 3 of these patients had to be admitted in the Hospital, 2 because of vomiting and 1 because a QTc interval lengthening. None of the patients needed to stop the HCQ or AZM and all the 80 patients finished the therapeutic strategy. From the group without pneumonia only a patient developed diarrhea that did not require hospitalization or stop the medication. ConclusionsOur strategy has been associated with a reduction in the burden of hospital pressure, and it seems to be successful in terms of the number of patients who have developed serious complications and / or death. None of the patients died in the studied period and only 6 have to be admitted in conventional hospitalization area.

Establishing a student-run free clinic in a major city in Northern Europe: a 1-year experience from Hamburg, Germany.

BACKGROUND: Student-Run Free Clinics (SRFCs) have been an integral part of US medical schools since the 1960s and provide health care to underserved populations. In 2018, we established an SRFC in Hamburg, Germany, a major city in Northern Europe. The aim of this study was to describe the central problems and to investigate the usefulness of an SRFC in a country with free access to medical care, such as Germany. METHODS: All consecutive patients treated at the SRFC Hamburg between February 2018 and March 2019 that consented to this study were analyzed regarding clinical characteristics, diagnosis, readmission rate and country of origin. RESULTS: Between February 2018 and March 2019, 229 patients were treated at the SRFC in Hamburg. The patients came from 33 different countries with a majority (n = 206, 90%) from countries inside the European Union. The most common reasons for visiting the SRFC were infections (23.2%), acute or chronic wounds (13.5%) and fractures (6.3%). CONCLUSION: Our multicultural patients suffer mainly from infections and traumatological and dermatological diseases. We find similarities to published Canadian SRFC patient cohorts but differences in diseases and treatment modalities compared to US SRFCs. Importantly, we demonstrate the relevance and necessity of the SRFC in a major city in Northern Europe.

Difficult-to-treat idiopathic nephrotic syndrome: established drugs, open questions and future options.

The idiopathic nephrotic syndrome in childhood can be classified according to the International Study of Kidney Disease in Children (ISKDC) based on the response to steroids. Typically, steroid-sensitive nephrotic syndrome (SSNS) is characterised by minimal changes in disease (MCD) histology, whereas in steroid-resistant nephrotic syndrome (SRNS) focal segmental glomerulosclerosis (FSGS) is the most prevalent lesion. Patients with SSNS may develop frequent relapses and/or steroid dependency, which can be difficult to treat. New studies confirm the value of calcineurin inhibitors (CNIs) and mycophenolic acid in preventing relapses of SSNS. Rituximab also plays an important role, but many questions regarding initial dosing, repetitions of courses, and long-term side effects remain unclear. SRNS, especially when unresponsive to treatment, can lead to chronic kidney disease. In particular, treatment with CNIs has improved the prognosis and recent data indicate that treatment can even be discontinued in many patients with full remission. In CNI-unresponsive SRNS, rituximab is less effective than in SSNS and the role of other biologicals (such as ofatumumab, abatacept, and others) remains unclear. A significant proportion of children with FSGS have genetic causes and most patients do not respond to immunosuppression, although individual patients with partial and even complete response have been documented. Future studies should evaluate treatments leading to long-term remission without maintenance immunosuppression in SSNS; in both genetic and immune-mediated SRNS, novel options to decrease the number of treatment-unresponsive patients seem mandatory, as they are at a high risk of developing end-stage renal disease.
