Ecological Survey of the Peridomestic Sand Flies of an Endemic Focus of Zoonotic Cutaneous Leishmaniasis in the South-East of Morocco.

Leishmaniasis is a parasitosis caused by parasites of the genus Leishmania and is transmitted by Phlebotominae sand flies. An entomological survey was carried out in different localities of Zagora Province. Our work allowed us to establish an inventory of sand flies to study potential vectors of leishmaniasis and to compare the composition and the specific abundance of different endemic stations. The sand flies were collected using CDC miniature light traps during the month of July 2019 in the ten studied villages. The results indicate the presence of thirteen species, belonging to the genera Phlebotomus and Sergentomyia. Phlebotomus papatasi was the predominant species (46.65%) followed by Ph. alexandri (17%), Ph. longicuspis (11.55%), Ph. bergeroti (1.53%) and Ph. sergenti (1.27%). Phlebotomus kazeruni (0.03%) was rare, and only one female was captured in Ifred. Sergentomyia schwetzi (8.69%) was the most prevalent species in the Sergentomyia genus followed closely by Se. fallax (6.84%). Sergentomyia africana was present with a proportion of (3.86%) followed by Se. clydei (1.96%). Sergentomyia dreifussi (0.46%), Se. antennata (0.08%), and Se. minuta (0.08%) were very limited. Phlebotomus papatasi, Ph. alexandri, Ph. bergeroti, Ph. longicuspis, Ph. sergenti, Se. schwetzi, Se. clydei, and Se. fallax are constant species, being present at least in 50% of the stations (occurrence> 50%). Common species (25%-49%) were Se. minuta and Se. africana and rare species were Ph. kazeruni and Se. antennata with a very limited distribution (occurrence <12%). The greatest species richness was found in Ksar Mougni and Ifred with the occurrence of 11 species, but overall, it was high (>9 species) in most of the villages. The Shannon-Wiener index was high (H' > 1) in eight localities (Ksar Mougni, Tassaouante, Bleida, ZaouiteLeftah, Ifred, Timarighine, Ait Oulahyane, and Ait Ali Ouhassou). The high value of this index is in favor of the ZaouiteLeftah locality (Shannon-Wiener index = 1.679) which is explained by the presence of a stand dominated by Ph. papatasi. In order to avoid exposure to infections, a good epidemiological surveillance and vector with rodent control measures must be well maintained. Awareness campaigns are also required and must be conducted for better knowledge of the disease.

Construction and analysis of a database for medication errors in a pharmacovigilance centre-the Moroccan experience.

PURPOSE: The study aimed to describe the epidemiological profile of medication errors (MEs) reported to the Moroccan Pharmacovigilance Center (MPVC), to determine factors associated with serious MEs, and to describe signals related to them. METHODS: We carried out a retrospective descriptive analysis of MEs reported to the MPVC from 2006 to 2016 and a secondary analysis of the seriousness of MEs with adverse drug reactions (ADRs). The reports were sorted by demographic profile and by ME and ADR characteristics. For signal detection, a quantitative approach was adopted, and the root cause analysis was completed. Epi info 7 software was used to perform descriptive and analytical statistics. The statistical significance level was set at p < 0.05. RESULTS: A total of 1618 ME reports were retrieved. The proportion of MEs associated with serious ADRs was 23.9%. The factors statistically associated with serious MEs were as follows: (i) the age group 16 years old and less (p < 0.001), (ii) the gender (p = 0.01), (iii) the administration and the prescription stages (p < 0.001), and (iv) the ME types related to inappropriate schedule of drug administration, drug prescribing error (p < 0.001), and incorrect drug administration dosage form (p = 0.04). Fourteen signals related to MEs were detected, for which risk minimization actions were implemented. CONCLUSION: The establishment of a ME unit within the MPVC was an opportunity to further improve the pharmacovigilance centre performance and consequently its contribution to medication safety. The lessons learned from MEs should be shared through pharmacovigilance networks and with institutions involved in medication safety for synergistic results to achieve patient safety worldwide.

Monitoring the safety of influenza A/H1N1 pandemic and seasonal vaccines in Morocco.

Background: A vaccination campaign against pandemic influenza A/H1N1 was implemented in Morocco between November 2009 and April 2010. Overall, 705,883 subjects were vaccinated by Pandemrix, Arepanrix, and Panenza. The adverse events following immunization (AEFIs) data comparison was made with the 2014/2015 seasonal influenza vaccination campaign that was specifically investigated. Aim: To evaluate the safety of the 2009 pandemic influenza A/H1N1 vaccine and to compare it to that of 2014 seasonal influenza vaccine. Methods: During the pandemic vaccination campaign, the Morocco Pharmacovigilance Centre reinforced passive AEFI surveillance with an active and prospective monitoring programme of 1000 immunized people over 6 months at 10 randomly selected vaccination centres. For the 2014/2015 seasonal vaccination campaign, AEFI data were collected from spontaneous notifications. Results: Active monitoring of 2009 pandemic collected 771 AEFI reports, corresponding to an AEFI incidence rate of 77.1% with vaccination by either Pandemrix or Arepanrix vaccine in 95% of cases. Reported AEFI were most frequently local (37.7%), general (29.5%), and neurological reactions (20.3%). Most of the AEFI (95.5%) were observed during the first 48 hours after vaccination, and the remainder within 2 weeks. None of the reported AEFI were serious case. The highest rate of notification was documented for health professionals, followed by patients with diabetes or chronic respiratory diseases. Concerning passive surveillance, the AEFI notification rate was significantly higher for the 2009/2010 pandemic vaccine (3.1 vs 1.2 per 10,000). However, there was no significant difference between pandemic and seasonal vaccination with regards to the serious adverse events (SAE) notification rate (0.3 vs 0.2 per 10,000). Conclusion: Data analysis indicates that the vaccines used against 2009 pandemic influenza in Morocco have a satisfactory safety profile, similar to the seasonal influenza vaccine with the exception of local reactions as observed previously in other countries.

[Serious gastrointestinal effects of nonsteroidal anti-inflammatory drugs (NSAIDS) in a prospective study in Morocco]. / Effets gastro-intestinaux majeurs des anti-inflammatoires non stéroïdiens (AINS): étude prospective marocaine.

In Morocco, the need for post-marketing surveillance of selective Cox2 inhibitors (coxibs) prompted a study to assess the serious gastrointestinal effects of NSAIDs and to compare gastrointestinal tolerance of conventional NSAIDs and coxibs. A prospective study was conducted from April 2001 through May 2002 among hospital-staff gastroenterologists in the public and private sector as well as emergency surgical units. Over this period, 123 patients were reported to have serious NSAID-related gastrointestinal effects, and 63% of them were admitted for bleeding or perforated ulcers. Endoscopy most often identified the lesion as a gastric ulcer (45%). Emergency rooms reported that aspirin was the most common causal agent and that NSAIDs accounted for 8.7% of bleeding and 9.3% of the perforated ulcers. Our findings indicate that men and youth are most vulnerable to serious gastrointestinal effects from these drugs. Several risk factors from the literature were confirmed in our population: history of gastrointestinal disorders and joint disease, occurrence within less than 1 month of beginning the drug; association of NSAIDs and aspirin, diabetes and hypertension. No conclusion could be drawn about the comparative gastrointestinal tolerance of conventional NSAIDs and coxibs, however, since the latter account for only 3% of the NSAID market.

Assessment of a new instrument for detecting preventable adverse drug reactions.

BACKGROUND: Pharmacovigilance centres (PVCs) in the World Health Organization (WHO) Programme for International Drug Monitoring have demonstrated their ability to detect preventable adverse drug reactions (ADRs) in their databases. In this field, there is no gold-standard method for detecting medication errors and evaluating ADR preventability. Therefore, we developed, from existing tools, a preventability assessment method: the 'P Method' (PM). OBJECTIVE: To present the PM and to evaluate its inter-rater reliability. METHODS: The PM includes 20 explicit criteria for assessing ADR preventability. This approach is based on identification of any potentially preventable risk factor that increases the likelihood of ADR occurrence. The outcome of the preventability assessment results in one of three possible scores: 'preventable', 'non-preventable' or 'not assessable'. The PM was tested in a multicentre study involving nine national PVCs. Two experienced reviewers at each participating PVC independently analysed the preventability of 183 ADRs, applying the PM. RESULTS: The overall agreement between all reviewers for assessment of ADR preventability was 'fair', with a kappa value of 0.27 [95 % confidence interval (CI) 0.21-0.40]. The level of agreement between reviewer pairs ranged from 'slight', with a kappa value of 0.12 (95 % CI -0.03 to 0.27), to 'substantial', with a kappa value of 0.69 (95 % CI 0.48-0.89). CONCLUSION: The analysis of the agreements and disagreements between reviewers highlighted where improvements might be made. Given that no standard assessment tool exists in the WHO Programme, the transparency of the assessment process in this method provides a substantial basis for further development and for support in signalling possible preventability.

[Acute intoxication by redoul (Coriaria myrtifolia L.). Three observations]. / Intoxication aiguë par le redoul (Coriaria myrtifolia L.). Trois observations.

INTRODUCTION: Coriaria myrtifolla L. (Redoul) is a shrub of the Mediterranean area. Poisoning with this plant is often accidental, following ingestion of the plant's fruit that are often mistaken for blackberries. OBSERVATIONS: Having eaten Coriaria myrtifolla L. berries, three sisters suffered from acute poisoning. One died. COMMENTS: Toxic effects are characterized by digestive (nausea, vomiting, abdominal pain), neurological (obnubilation, convulsions and their complications), and respiratory disorders (polypnea, respiratory problems, apnea, short and superficial respiration) together with myositis of the pupils. Treatment of this poisoning is purely symptomatic. In the case of convulsions, rapid resuscitation in an intensive care unit in necessary.

Pharmacovigilance and moroccan tuberculosis public program: current situation.

The objective of this work is to demonstrate the interest of integration of pharmacovigilance in Moroccan Tuberculosis Control Program (MTCP). Design and Data Collection. The integration of pharmacovigilance in MTCP was conducted in October 2012 with the Global Fund support. We compared the reports notified before and after this integration (period 1: January 2010-October 2012; period 2: October 2012-December 2013). The detection of signals was based on the Information Component available in VigiMine. We used the SPSS version 10.0 and MedCalc version 7.3 for data analysis. Results. The average number of spontaneous reports increased from 3.6 to 37.4 cases/month (P < 10(-3)). The average age was 40.7 ± 17.5 years; the sex ratio was 0.8. Hepatic reactions (32.7%) predominated during the first period, while skin reactions (24.1%) were in the second period (P = 10(-4)), and 40.9% of cases in the first period were serious against 15.8% in second period (P = 0.003). Nine signals were generated (hepatic enzyme increase, cholestasis, jaundice, arthralgia, acne, lower limb edema, pruritus, skin rashes, and vomiting). Conclusion. The integration of pharmacovigilance in Moroccan Tuberculosis Control Program improved the management of ADRs and detected new signals of antituberculosis drugs.

The involvement of Pharmacovigilance Centres in medication errors detection: a questionnaire-based analysis.

OBJECTIVES: This study assesses the ability of Pharmacovigilance Centres (PVCs) to detect medication errors (ME) and to proceed to building Patient Safety (PS) via their information networks and to underline the limits for this challenge. METHODS: This was an exploratory study conducted in PVCs members of the World Health Organization International Drug Monitoring network. A questionnaire specifically designed for the needs of the study was sent to a network via a confidential email system. The questionnaire asked for information, progress and improvement made by PVCs in PS and ME. RESULTS: Among the 88 countries, 21 answered. Reporting of Adverse Drug Reactions (ADRs) by health care professionals (HCP) is mandatory for 42% of PVCs. 100% of countries receive reports from HCP, 66% from patients and 24% from PCCs. ADRs reports are received by all communications means. There is an heterogeneity between countries regarding PVCs and PS activities. Among them, 4 PVCs have the prime activity of PS organization. CONCLUSION: PVCs are able to detect and analyze ME. There is a need to coordinate efforts between countries to optimize ME detection, and its analysis. Bridges need to be built linking PVCs, PCCs and PS organizations in order to avoid duplication of workload.

Incidence of adverse drug events and medication errors in intensive care units: a prospective multicenter study.

BACKGROUND: In recent years, medication error has received considerable attention because it causes substantial mortality, morbidity, and additional health care costs. Collecting information in this field depends on the willingness of health professionals to report their errors. Another important point is to identify patients at high risk for an adverse drug event (ADE) to oversee the quality of the entire drug distribution chain, including prescription, drug choice, dispensing, and preparation to the administration of drugs. OBJECTIVE: To assess the prevalence rate of ADEs. To ascertain those related to medication errors to develop prevention strategies. DESIGN: Prospective cohort study. SETTING: Multicenter study, 7 intensive care unit in academic and military hospital of Rabat. PERIOD: Three months. PATIENTS: Adult and pediatric patients in medical/surgical intensive care units. COLLECTION DATA: One coordinator for each participating ward collaborates with a pharmacist investigator from Moroccan pharmacovigilance center in the detection of ADEs. MEASUREMENTS AND MAIN RESULTS: Of the 696 patients studied, the investigators identified 108 incidents (15.5 %) (95% confidence interval, 14.1-16.9). The reviewers concluded that 56 (70%) of 80 ADEs were nonpreventable, which, by definition, are considered as ADRs. Among the 52 medication errors, 28 (53.8%) led to potential ADEs and 24 (46.2%) led to actual preventable ADEs. There were 7.7 medication errors for 1000 patient-days. We noted that the preventable ADEs occurred in the prescribing (71.1%), administration (21.2%), transcription (5.7%), and dispensing stages. Errors of wrong or improper drug use accounted for the majority of potential and actual preventable ADEs (23%), followed by improper dose (21.1%), wrong duration of treatment (19.2%),wrong rate of administration(13.5), errors due to drug omission (9.6%), wrong administration technique (5.8%), wrong dosage form (3.8%), and wrong administration timing (1.9%). CONCLUSIONS: This study argues the need for pharmacovigilance to extend its scope to medication errors to improve the safety of drugs. Our results underlined that medication errors are likely to be more serious than ADRs. Our approach based on the collaboration between the pharmacovigilance center and clinicians can be a powerful tool for incorporating error reporting into the culture of medicine.
