COVID-19: Patient care after discharge from the Intensive Care Unit.

INTRODUCTION: The Ibn Rochd CHU is a tertiary care structure that provides care for the most severe cases of COVID-19 requiring hospitalisation in intensive care. The objective of study is to describe the complementary medical and psychological care of patients with COVID-19 in the endocrinology department after a stay in intensive care. PATIENTS AND METHODS: This is a descriptive observational study of patients transferred from the intensive care unit to the endocrinology service following a COVID-19 infection during the period from 17 April 2020 to May 26, 2020. Clinical characteristics of the patients and complications related to COVID-19 infection were studied; a nutritional assessment using the MNA nutritional status assessment questionnaire; psychological assessment using quality-of-life questionnaires (Hamilton depression and anxiety, HAD, SF36, PCLS); a treatment satisfaction questionnaire (TQCMII) and an assessment of patient autonomy by the ADL score. RESULT: Our study included 41 patients with an average age of 55 years (19-85 years), a sex ratio M/F of 1.05, 43.9% were diabetic, 34.1% hypertensive, 4.9% asthmatic and 5% obese, and 51.2% were severe and critical cases. The average ICU stay is 8.42 days, requiring intubation in 12.2% of cases. All patients were treated with the Hydroxychloroquine, Azithromycin, vitamin C, zinc and corticosteroid protocol, 14.6% had undernutrition and 65.9% had a risk of undernutrition. The average BMI was 25.34 kg/m2 (17-42), 61% had experienced weight loss, which was greater than 8 kg in 26.1% of cases, 12.2% of patients were not autonomous, 12.2% had moderate depression, 2.4% severe depression, 14.6% mild to moderate anxiety, 12.2% severe anxiety and 29.3% suffered acute post-traumatic stress disorder. CONCLUSION: Patients with COVID-19 are, in addition to the complications from coronavirus infection, vulnerable to undernutrition, psychological and motor complications. Additional care before discharge is essential for better integration of patients into their families.

Nutritional status assessment in patients with Covid-19 after discharge from the intensive care unit.

INTRODUCTION: The nutritional diagnosis and early nutritional management of COVID-19 patients must be integrated into the overall therapeutic strategy. The aim of our study is to assess the nutritional status of patients with COVID-19 after a stay in intensive care, to describe the prevalence of undernutrition, to determine the factors influencing undernutrition and to describe the nutritional management. TOOLS AND METHODS: This is a descriptive observational study of adult patients admitted to the endocrinology service for additional care after a stay in intensive care during the period from April 17, 2020 to May 26, 2020. The assessment tool used was the Mini Nutritional Assessment (MNA). RESULTS: Our study included 41 patients; the average age of the patients was 55 years, 51.2% had a severe or critical form of COVID-19, 75.6% stayed in intensive care, 12.2% had a loss of autonomy. The average BMI was 25.2 kg/m2 (17-42 kg/m2), 42.5% were overweight, 61% had weight loss, 26.2% had weight loss greater than 10%, 14.6% of our patients were undernourished, 65.9% were at risk of undernutrition, 19.5% had hypoalbuminemia, 17.1% had hypoprotidemia, 19.5% hypocalcemia, 34.1% anemia, 12.2% hypomagnesemia and 51.2% had a deficiency in vitamin D. A positive correlation was found between poor nutritional status and a longer stay in intensive care (>5 days) (p = 0.011) and lymphopenia (p = 0,02). CONCLUSION: Despite a personalized diet, 14.6% of patients presented undernutrition. Particular attention should be paid to patients with a long stay in intensive care.

Seroprevalence of Leptospirosis among High-Risk Individuals in Morocco.

BACKGROUND: Leptospirosis is an anthropozoonotic reemerging neglected infectious disease underreported in most developing countries. A cross-sectional study was performed between 17 and 23 February 2014 to estimate the seroprevalence of leptospirosis among high-risk populations in Casablanca (Morocco). METHODS: A total of 490 human serum samples (97.6% males) were collected in 3 high-risk occupational sites including the biggest meat slaughterhouse (n = 208), a poultry market (n = 121), and the fish market (n = 161). A total of 125 human blood samples were also collected from the general population and used in this study as a control group. To detect the presence of anti-Leptospira, sera were screened with in-house IgG and IgM enzyme-linked immunosorbent assay (ELISA). Positive samples were tested by Microscopic Agglutination Technique (MAT) using a panel of 24 serovar cultures and cut point of 1 : 25. RESULTS: Seroprevalence of leptospirosis among the control group was 10.4% (13/125). A high seropositivity among the overall seroprevalence of 24.1% (118/490) was observed in the high-risk groups of which 7.3% (36/490), 13.7% (67/490), and 3.1% (15/490) were for anti-Leptospira IgM, IgG, and both IgG and IgM antibodies, respectively. Most of the positive individuals were occupationally involved in poultry (37.2%), followed by the market fish (26.1%) and the meat slaughterhouse (14.9%) workers. Among all ELISA-positive serum samples, 20.3% (n = 24) had positive MAT responses, of which the Icterohaemorrhagiae (n = 7) is the most common infecting serogroup followed by Javanica (4), Australis (2), and Sejroe, Mini, and Panama (one in each). In the remaining 8 MAT-positive sera, MAT showed equal titers against more than one serogroup. CONCLUSION: Individuals engaged in risk activities are often exposed to leptospiral infection. Therefore, control and prevention policies toward these populations are necessary.

Occurrence of plasmid-mediated quinolone resistance and virulence genes in avian Escherichia coli isolates from Algeria.

INTRODUCTION: The emergence and spread of quinolone-resistant Escherichia coli in poultry products puts consumers at risk of exposure to the strains of E. coli that resist antibiotic treatment. The objective of this study was to define the prevalence and virulence potential of poultry-associated nalidixic acid (NAL)-resistant E. coli in the Annaba city, Algeria. METHODOLOGY: In total, 33 samples of retail chicken meat were purchased from various butcher shops and examined for bacterial contamination with NAL-resistant E. coli. These isolates were subjected to antimicrobial susceptibility testing and were also investigated for the presence of plasmid-mediated quinolone resistance (PMQR) genes and virulence genes using conventional polymerase chain reaction (PCR) and DNA sequencing. Phylogenetic grouping of the NAL-resistant E. coli isolates was determined by the conventional multiplex PCR method. RESULTS: Twenty-nine (87.8%) products yielded NAL-resistant E. coli. Antibiograms revealed that 96.55% of NAL-resistant E. coli isolates were multidrug resistant (MDR). Resistance was most frequently observed against sulfamethoxazole-trimethoprim (96.6%), tetracycline (96.6%), ciprofloxacin (72%), and amoxicillin (65.5%). Group A was the most prevalent phylogenetic group, followed by groups D, B1, and B2. The PMQR determinants were detected in three isolates with qnrB72 and qnrS1 type identified. Four (13.8%) isolates carried one of the Shiga toxin E. coli-associated genes stx1, stx2, and ehxA alleles. CONCLUSIONS: The high prevalence of NAL-resistant E. coli isolated from retail chicken meat with detection of MDR E. coli harboring Shiga toxin genes in this study gives a warning signal for possible occurrence of foodborne infections with failure in antibiotic treatment.

Intestinal carriage of vancomycin-resistant enterococci in a community setting in Casablanca, Morocco.

This study aimed to determine the rate of intestinal carriage of vancomycin-resistant enterococci (VRE) and to perform a phenotypic and genotypic characterisation of VRE isolates in the community in Casablanca, Morocco. During 6 months in 2014, 113 faecal samples were examined for the presence of enterococci. Antibiotic susceptibility of the isolates was determined by the disk diffusion method. Phenotypic and genotypic species identification was performed, and the vanA, vanB and vanC genes were detected by PCR. Each bacterial isolate resistant to vancomycin was subjected to amplification and sequencing of the 16S rRNA gene. In total, 100 strains were collected from a community population of 80 persons; 55% of the isolates were identified as Enterococcus faecium and 45% as Enterococcus faecalis. The resistance profile showed that 88% of the strains were multiresistant. The rate of faecal carriage of VRE was 21% (n=21), among which 8 strains were E. faecalis (17.8% of all E. faecalis) and 13 strains were E. faecium (23.6% of all E. faecium). PCR analysis revealed that all of the strains were resistant to vancomycin owing to possession of the vanA gene. The emergence of VRE and the high rate of colonisation by multiresistant enterococci are alarming. Strict measures are required to control the further spread of these strains in the Moroccan community.

Fecal carriage of extended-spectrum ß-lactamase-producing Enterobacteriaceae in community setting in Casablanca.

BACKGROUND: The importance of community-acquired infections due to extended-spectrum ß-lactamase-producing Enterobacteriaceae (ESBL-PE) has been increasingly recognized in recent years. This study aimed to determine the prevalence of intestinal carriage of ESBL-PE in the community in Casablanca, Morocco. METHODS: During 6 months (2013), 93 fecal samples were examined for ESBL-PE. Isolates expressing an ESBL phenotype were investigated for the presence of genes encoding ß-lactamases and plasmid-mediated quinolone resistance. Conjugation experiments were done to determine the mobility of ESBL genes. RESULTS: The prevalence of fecal carriage of ESBL-PE was 4.3% (4/93; 95% CI, 0.2-8.4). Klebsiella pneumoniae (n = 2), Enterobacter cloacae (n = 2), Escherichia coli (n = 1), and Serratia odorifera (n = 1) were the ESBL-producing species. Four (66.7%) of these isolates were multidrug-resistant. The blaSHV-12 (n = 5) was the most frequent ESBL gene detected, followed by blaCTX-M-15 (n = 3).The non-ESBL gene detected was blaTEM-1 (n = 5). One isolate harbored the qnrB1 variant. RESULTS of conjugation experiments indicated that blaSHV-12 + blaTEM-1 + qnrB1 and blaCTX-M-15 + blaTEM-1 genes were co-transferred and that these genes were carried by a conjugative plasmid of high molecular weight (125 kb). CONCLUSION: Our results show the importance of the intestinal tract as a reservoir for ESBL-PE in the community in Morocco.

[Isolation of Bordetella trematum from bacteremia]. / Isolement de Bordetella trematum au décours d'une bactériémie.

The species Bordetella trematum was first described in 1996. Currently only eleven cases were published. We describe the first case of Bordetella trematum issued from bacteremia with a patient who has severe burns in Morocco. The identification was not possible by conventional microbiological methods where the resort to 16S ARNr sequencing. The use of molecular methods, including sequencing of the 16S ARNr, is currently an essential complementary tool to identify microbiological pathogens.

Vaccination with Haemophilus influenzae type b conjugate vaccine reduces bacterial meningitis in Morocco.

INTRODUCTION: Haemophilus influenzae type b (Hib) is a leading cause of bacterial meningitis and pneumonia and can be prevented by Hib vaccine. We conducted a vaccine impact evaluation to support continued use of Hib vaccine in Morocco following introduction in 2007. METHODS: Bacterial meningitis surveillance data from 2004 to 2009 were obtained from 11 sentinel hospitals located in eight provinces and one prefecture in Morocco to examine Hi meningitis reporting for cases aged <5 years. We defined the years of 2004-2006 as the pre-vaccine period and 2008-2009 as the post-vaccine period and compared the mean annual number of confirmed Hi meningitis cases for these time periods using a Chi-square test. We calculated the minimum incidence of Hi meningitis during the evaluation period in Grand Casa Prefecture, where the catchment population could be estimated. RESULTS: From 2004 to 2009, 1844 suspected meningitis case-patients aged <5 years were reported; 354 (19.2%) were confirmed with bacterial meningitis, including 105 (29.7%) Hi cases. The mean annual number of confirmed Hi meningitis cases decreased by 75%, from 24 in the pre-vaccine period to 6 during the post-vaccine period (p<0.001). Assuming Hi cases with unknown age were <5 years of age, the estimated minimum incidence of confirmed Hi meningitis in Grand Casa Prefecture decreased by 93%, from 15 cases per 100,000 children in the pre-vaccine period to 1 case per 100,000 children in the post-vaccine period. CONCLUSION: Hib vaccine introduction likely significantly reduced the occurrence of Hi meningitis among children aged <5 years at the 11 sentinel hospitals included in this evaluation in Morocco, suggesting that continued use of Hib vaccine in Morocco would be beneficial.

Plasmid-mediated quinolone resistance in expanded spectrum beta lactamase producing enterobacteriaceae in Morocco.

INTRODUCTION: Although independently acquired, plasmid-mediated quinolone resistance appears to be linked with extended-spectrum or AmpC-type beta-lactamases. Since no data are available in African countries, the prevalence of qnr genes at the University Hospital Ibn Rochd, Casablanca, Morocco, was investigated. METHODOLOGY: Between October 2006 and March 2007, the following 39 randomly selected non-duplicate Enterobacteriaceae producing an extended-spectrum beta-lactamase (ESBL), representing 20% of ESBL strains with respect to species and ward origin, were collected: Escherichia coli (n = 16); Klebsiella spp (n = 14); Enterobacter cloacae (n = 8); Proteus mirabilis (n = 1). Antibiotic susceptibility testing was performed according to CLSI guidelines. ESBL detection was performed by the double disc diffusion test. A multiplex PCR was conducted to detect qnrA, qnrB and qnrS genes that were confirmed by sequencing of the PCR product. RESULTS: The estimated overall prevalence of qnr reached 36% (n = 14; qnrA, 10.25%; qnrB, 23.07%; qnrS, 2.56%). Genes were identified in E. coli, Klebsiella and Enterobacter with a respective prevalence of 18.7%, 50% and 62.5%.  The qnr genes were detected in nine wards and qnrA1, qnrB1-B2-B4 and qnrS1 variants were identified. Three genes were identified among nalidixic acid susceptible strains (n = 6); three of those were also susceptible to ciprofloxacin. Among nalidixic acid and ciprofloxacin resistant strains, all strains had qnrB. CONCLUSIONS: This study highlights the high prevalence of qnr genes among ESBL strains in the Ibn Rochd CHU, Casablanca. Moreover, qnr were present in quinolone-susceptible strains which could lead to in vivo selection of ciprofloxacin-resistant strains.
