Infections with Listeria monocytogenes (LM) are very uncommon and severe especially in immunocompromised people. We report a continuous cycling peritoneal dialysis (CCPD) patient who presented initially disseminated listeriosis with peritonitis. He was successfully treated with intraperitoneal and intravenous ampicillin but died unfortunately from a cardiorespiratory arrest due to food inhalation. It is the 20th case of such peritonitis mentioned among PD patients and the first reported in Belgium. This case illustrates the importance of a systematic approach to get quick diagnosis and effective antibiotic readjustment. Empiric therapy is not effective on Listeria which is naturally resistant to cephalosporins and poorly sensitive to vancomycin. Ampicillin is the first-line antibiotic. In case of penicillin allergy, trimethoprim–sulfamethoxazole or erythromycin can be used successfully. Identification of LM serotype has a prognostic value. PD educative programmes should recommend to avoid unpasteurized dairy products to prevent listeriosis.

BACKGROUND: Cancer seems to have an independent adverse prognostic effect on COVID-19-related mortality, but uncertainty exists regarding its effect across different patient subgroups. We report a population-based analysis of patients hospitalised with COVID-19 with prior or current solid cancer versus those without cancer. METHODS: We analysed data of adult patients registered until 24 May 2020 in the Belgian nationwide database of Sciensano. The primary objective was in-hospital mortality within 30 days of COVID-19 diagnosis among patients with solid cancer versus patients without cancer. Severe event occurrence, a composite of intensive care unit admission, invasive ventilation and/or death, was a secondary objective. These endpoints were analysed across different patient subgroups. Multivariable logistic regression models were used to analyse the association between cancer and clinical characteristics (baseline analysis) and the effect of cancer on in-hospital mortality and on severe event occurrence, adjusting for clinical characteristics (in-hospital analysis). RESULTS: A total of 13 594 patients (of whom 1187 with solid cancer (8.7%)) were evaluable for the baseline analysis and 10 486 (892 with solid cancer (8.5%)) for the in-hospital analysis. Patients with cancer were older and presented with less symptoms/signs and lung imaging alterations. The 30-day in-hospital mortality was higher in patients with solid cancer compared with patients without cancer (31.7% vs 20.0%, respectively; adjusted OR (aOR) 1.34; 95% CI 1.13 to 1.58). The aOR was 3.84 (95% CI 1.94 to 7.59) among younger patients (

Hydroxychloroquine has been used worldwide as a first-line treatment for patients hospitalized with COVID-19. Little is known about COVID-19 and its effects on patients with congenital red blood cell disorders. We report a case of haemolytic anaemia in a 32-year-old patient and a fortuitous highlighting of G6PD deficiency. We reviewed the literature to assess the risk of hydroxychloroquine use in this context. LEARNING POINTS: A rapid drop in haemoglobin in COVID-19 patients should alert physicians to test for haemolytic anaemia and enzymopathies. Our review of the literature shows that use of hydroxychloroquine is safe in G6PD-deficient patients.

Highlights • Hydroxychloroquine (HCQ) 2400 mg over 5 days was used in Belgium for COVID-19. • Impact of HCQ on mortality among 8075 patients with COVID-19 was assessed. • Lower mortality in HCQ-treated patients as compared to supportive care. • Lower mortality was irrespective of symptom duration., Hydroxychloroquine (HCQ) has been largely used and investigated as therapy for COVID-19 across various settings at a total dose usually ranging from 2400 mg to 9600 mg. In Belgium, off-label use of low-dose HCQ (total 2400 mg over 5 days) was recommended for hospitalised patients with COVID-19. We conducted a retrospective analysis of in-hospital mortality in the Belgian national COVID-19 hospital surveillance data. Patients treated either with HCQ monotherapy and supportive care (HCQ group) were compared with patients treated with supportive care only (no-HCQ group) using a competing risks proportional hazards regression with discharge alive as competing risk, adjusted for demographic and clinical features with robust standard errors. Of 8075 patients with complete discharge data on 24 May 2020 and diagnosed before 1 May 2020, 4542 received HCQ in monotherapy and 3533 were in the no-HCQ group. Death was reported in 804/4542 (17.7%) and 957/3533 (27.1%), respectively. In the multivariable analysis, mortality was lower in the HCQ group compared with the no-HCQ group [adjusted hazard ratio (aHR) = 0.684, 95% confidence interval (CI) 0.617–0.758]. Compared with the no-HCQ group, mortality in the HCQ group was reduced both in patients diagnosed ≤5 days (n = 3975) and >5 days (n = 3487) after symptom onset [aHR = 0.701 (95% CI 0.617–0.796) and aHR = 0.647 (95% CI 0.525–0.797), respectively]. Compared with supportive care only, low-dose HCQ monotherapy was independently associated with lower mortality in hospitalised patients with COVID-19 diagnosed and treated early or later after symptom onset.

We observed a 76-year-old man who presented “acute kidney-lung failure” 9 months after intravesical Bacillus Calmette-Guerin (BCG) adjuvant treatment for a T1 bladder cancer. He had inflammatory infiltration on chest radiography and required dialysis for acute renal failure. A percutaneous renal biopsy was performed and revealed tubulointerstitial nephritis with a moderate eosinophilic infiltrate without granulomatous lesion. After a few days, an open lung biopsy was also done due to respiratory deterioration. The anatomopathologic specimen demonstrated moderate fibrosis with lympho-neutrophilic infiltration and few aspecific granulomatous lesions without caseous necrosis. Sarcoidosis was suspected and high dose oral methylprednisolone was started. Three weeks later, Mycobacterium bovis was identified by Polymerase Chain Reaction on open lung biopsy. He responded well to steroids and tuberculostatic tri-therapy. After one month of immunosuppressive treatment, renal function was resolved and hemodialysis could be discontinued. Despite the frequent use of adjuvant BCG immunotherapy, systemic complications such as hepatitis, pneumonitis, spondylodiscitis or multiorgan failure are rare (
