[The importance of the logistic warehouse in pandemic period: the experience of the USL Umbria 1 (Perugia, Italy) during covid-19.] / L'importanza del magazzino logistico in periodo di pandemia: l'esperienza dell'USL Umbria 1 durante covid-19.

The pandemic period has generated major problems in the pharmacies of hospitals and local health care companies regarding the distribution of drugs to patients undergoing treatment with chronic drugs. This is because the patient, during the lockdown, was forced to leave the house and go several miles away to reach the place where the drug was dispensed. Moreover, very often, the place was placed in covid-19 hospitals, like the one in Perugia, and was also a risk for the patient himself. The logistical organization allows, in addition to the advantages of traceability, efficiency and savings, with the arrival of the drug at home, a very high patient compliance that also translates into greater security in a pandemic period. To the Usl Umbria 1 of Perugia (Italy) has been centralized the activity of warehouse for all the South area that includes three hospitals and four sanitary districts. Such warehouse, through computerized procedure, guarantees the direct distribution with sending of the medicines directly to the district of belonging of the patient. In this way the patient was not forced to make long and risky trips to continue their chronic therapies. Moreover, this logistic warehouse has also allowed to cope with the correct management of many medicinal specialties that have been used against the SARS-CoV-2 virus avoiding their temporary deficiency for patients already on therapy according to the normal therapeutic indications (anti-inflammatory, antiretroviral and immunomodulatory). This paper aims to demonstrate how logistical organization is of vital importance for a National Health System that has to face increasing costs, ensure the traceability of all processes and, last but not least, survive a worldwide pandemic period.

Physical wastage of immunobiological products in the state of Ceará, Brazil, 2014-2016. / Perdas físicas de imunobiológicos no estado do Ceará, 2014-2016.

OBJECTIVE: to describe discarded wasted immunobiological products provided by the National Im-munization Program (PNI) to the State of Ceará between 2014 and 2016, and the costs of discarded doses. METHODS: this was a descriptive study using data from suspect im-munobiological product evaluation forms and data from disposal approval forms. RESULTS: a total of 317 forms were included, 72.0% of which had a disposal approval form, and 160,767 discarded doses were identified, at a total cost of BRL 1,834,604.75; wastage accounted for 0.45%, 0.93% and 0.53% of the total cost of vaccines in 2014, 2015 and 2016, respectively; the main reason for the wastage identified was electric power shortage (54.9%). CONCLUSION: we identified a large number of discarded wasted doses, with high absolute cost; tighter control is necessary, as failures in conservation dynamics may interfere with the supply of immunobiologicals.

Overview of rabies post-exposure prophylaxis access, procurement and distribution in selected countries in Asia and Africa, 2017-2018.

BACKGROUND: Rabies is a neglected zoonotic disease with a global burden of approximately 59,000 human deaths a year. Once clinical symptoms appear, rabies is almost invariably fatal; however, with timely and appropriate post-exposure prophylaxis (PEP) consisting of wound washing, vaccine, and in some cases rabies immunoglobulin (RIG), the disease is almost entirely preventable. Access to PEP is limited in many countries, and when available, is often very expensive. METHODS: We distributed a standardized assessment tool electronically to a convenience sample of 25 low- and middle-income countries in Asia and Africa to collect information on rabies PEP procurement, forecasting, distribution, monitoring and reporting. Information was collected from national rabies focal points, focal points at the World Health Organization (WHO) country offices, and others involved in procurement, logistics and distribution of PEP. Because RIG was limited in availability or unavailable in many countries, the assessment focused on vaccine. Data were collected between January 2017 and May 2018. RESULTS: We received responses from key informants in 23 countries: 11 countries in Asia and 12 countries in Africa. In 9 of 23 (39%) countries, rabies vaccine was provided for free in the public sector and was consistently available. In 10 (43%) countries, all or some patients were required to pay for the vaccine in the public sector, with the cost of a single dose ranging from US$ 6.60 to US$ 20/dose. The primary reason for the high cost of the vaccine for patients was a lack of funding at the central level to subsidize vaccine costs. In the remaining 4 (17%) countries, vaccine was provided for free but was often unavailable so patients were required to purchase it instead. The majority of countries used the intramuscular route for vaccine administration and only 5 countries exclusively used the dose-sparing intradermal (ID) route. Half (11/22; 50%) of all countries assessed had a standardized distribution system for PEP, separate from the systems used for routine childhood vaccines, and almost half used separate storage facilities at both central and health facility levels. Approximately half (9/22; 41%) of all countries assessed reported having regular weekly, monthly or quarterly reporting on rabies vaccination. CONCLUSIONS: While all countries in our assessment had rabies vaccines available in the public sector to some extent, barriers to access include the high cost of the vaccine to the government as well as to patients. Countries should be encouraged to use ID administration as this would provide access to rabies vaccine for many more people with the same number of vaccine vials. In addition, standardized monitoring and reporting of vaccine utilization should be encouraged, in order to improve data on PEP needs.

Rabies vaccine and immunoglobulin supply and logistics: Challenges and opportunities for rabies elimination in Kenya.

Prompt provision of post-exposure-prophylaxis (PEP) including vaccines and rabies immunoglobulin (RIG) to persons bitten by suspect rabid dogs is a key strategy to eliminating human deaths from dog-mediated rabies in Kenya by 2030. We assessed the availability, forecasting and supply chain logistics for rabies PEP in Kenya, compared with the system used for vaccines in the expanded program of immunization (routine vaccines). Semi-structured questionnaires capturing data on forecasting, procurement, distribution, cold chain and storage, monitoring and reporting for routine vaccines and rabies vaccines and RIG were administered to 35 key personnel at the national, county, sub-county and health facility levels in five counties. Results showed large variability in PEP availability (stockouts ranged from 3 to 36 weeks per year) with counties implementing rabies elimination activities having shorter stockouts. PEP is administered intramuscularly using the 5-dose Essen regimen (day 0, 3, 7, 14 and 28). PEP costs to bite patients were reported to range from 10 to 15 US dollars per dose; RIG was seldom available. A less robust supply and logistics infrastructure is used for rabies PEP compared to routine vaccines. Forecasting and monitoring mechanisms for rabies PEP was poor in the study counties. The supply of vaccines from the national to the sub-national level is mainly through two government agencies and a private agency. Since government decentralization, the National Vaccine and Immunization Program has remained as the main supplier of the routine vaccines, playing a lesser role in the supply of rabies biologicals. Adoption of the dose-saving intradermal route for PEP administration, reduction of PEP costs to patients, and placing rabies vaccines within the routine vaccines supply and logistics system would significantly improve PEP availability and accessibility to persons at risk of rabies; a critical step to achieving elimination of human deaths from rabies.

The continuing burden of Rh disease 50 years after the introduction of anti-Rh(D) immunoglobin prophylaxis: call to action.

Severe morbidity and death because of Rh disease have only been reduced by approximately 50% globally during the last 50 years, despite the advent of anti-Rh(D) immunoglobin prophylaxis, which has resulted in >160,000 perinatal deaths and 100,000 disabilities annually. This apparent failure to take appropriate preventive measures is of great concern. Thus, there is a great need to do much better. We wish to draw attention to the unnecessary continuing burden of Rh disease, to discuss some of the reasons for this failure, and to provide suggestions for a better way forward.

Global characteristics of the rabies biologics market in 2017.

In 2017, the World Health Organization, the World Organisation for Animal Health, the Food and Agriculture Organization of the United Nations and the Global Alliance for Rabies control developed a strategic plan to end human rabies deaths by 2030. A survey for manufacturing capacity and product characteristics of rabies biologics was conducted to inform this process. Twenty-three of 42 manufacturers, responded, giving a market capacity for 2017 of 90 million vials for human vaccines, 2.5 million vials for rabies immunoglobulins, 2 million vials for monoclonal antibodies and 181 million vials for dog vaccines. Production capacity could be increased by many manufacturers but was limited by country demand, lack of long-term planning and restricted market expansion. Should countries implement national rabies elimination programmes where biologic needs are forecasted and production lead times respected, manufacturers can meet future supply needs towards global elimination of human dog-mediated rabies deaths.

Descriptive assessment of rabies post-exposure prophylaxis procurement, distribution, monitoring, and reporting in four Asian countries: Bangladesh, Bhutan, Cambodia, and Sri Lanka, 2017-2018.

BACKGROUND: There are approximately 35,000 human deaths from rabies in Asia annually. Rabies can be prevented through timely post-exposure prophylaxis (PEP) consisting of wound washing, rabies vaccine, and in some cases, rabies immunoglobulin (RIG). However, access to rabies PEP often remains limited to urban areas and is cost-prohibitive. There is little information on procurement, distribution, monitoring, and reporting of rabies PEP. METHODS: We interviewed key informants in the public sector from various levels in Bangladesh, Bhutan, Cambodia, and Sri Lanka between March 2017 and May 2018 using a descriptive assessment tool to obtain information on procurement, distribution, monitoring, and reporting of rabies PEP. These four countries in Asia were chosen to showcase a range of rabies PEP systems. National rabies focal points were interviewed in each country and focal points helped identify additional key informants at lower levels. RESULTS: A total of 22 key informants were interviewed at various levels (central level to health facility level) including national rabies focal points in each country. Each country has a unique system for managing rabies PEP procurement, distribution, monitoring, and reporting. There are varying levels of PEP access for those with potential rabies exposures. Rabies PEP is available in select health facilities throughout the country in Bangladesh, Bhutan, and Sri Lanka. In Cambodia, rabies PEP is limited to two urban centers. The availability of RIG in all four countries is limited. In these four countries, most aspects of the rabies PEP distribution system operate independently of systems for other vaccines. However, in Bhutan, rabies PEP and Expanded Programme on Immunization (EPI) vaccines share cold chain space in some locations at the lowest level. All countries have a monitoring system in place, but there is limited reporting of data, particularly to the central level. CONCLUSION: Systems to procure, deliver, monitor, and report on rabies PEP are variable across countries. Sharing information on practices more widely among countries can help programs to increase access to this life-saving treatment.

The need to improve access to rabies post-exposure vaccines: Lessons from Tanzania.

BACKGROUND: Rabies is preventable through prompt administration of post-exposure prophylaxis (PEP) to exposed persons, but PEP access is limited in many rabies-endemic countries. We investigated how access to PEP can be improved to better prevent human rabies. METHODS: Using data from different settings in Tanzania, including contact tracing (2,367 probable rabies exposures identified) and large-scale mobile phone-based surveillance (24,999 patient records), we estimated the incidence of rabies exposures and bite-injuries, and examined health seeking and health outcomes in relation to PEP access. We used surveys and qualitative interviews with stakeholders within the health system to further characterise PEP supply and triangulate these findings. RESULTS: Incidence of bite-injury patients was related to dog population sizes, with higher incidence in districts with lower human:dog ratios and urban centres. A substantial percentage (25%) of probable rabies exposures did not seek care due to costs and limited appreciation of risk. Upon seeking care a further 15% of probable rabies exposed persons did not obtain PEP due to shortages, cost barriers or misadvice. Of those that initiated PEP, 46% did not complete the course. If no PEP was administered, the risk of developing rabies following a probable rabies exposure was high (0.165), with bites to the head carrying most risk. Decentralized and free PEP increased the probability that patients received PEP and reduced delays in initiating PEP. No major difficulties were encountered by health workers whilst switching to dose-sparing ID administration of PEP. Health infrastructure also includes sufficient cold chain capacity to support improved PEP provision. However, high costs to governments and patients currently limits the supply chain and PEP access. The cost barrier was exacerbated by decentralization of budgets, with priority given to purchase of cheaper medicines for other conditions. Reactive procurement resulted in limited and unresponsive PEP supply, increasing costs and risks to bite victims. CONCLUSION: PEP access could be improved and rabies deaths reduced through ring-fenced procurement, switching to dose-sparing ID regimens and free provision of PEP.

II Brazilian Consensus on the use of human immunoglobulin in patients with primary immunodeficiencies.

In the last few years, new primary immunodeficiencies and genetic defects have been described. Recently, immunoglobulin products with improved compositions and for subcutaneous use have become available in Brazil. In order to guide physicians on the use of human immunoglobulin to treat primary immunodeficiencies, based on a narrative literature review and their professional experience, the members of the Primary Immunodeficiency Group of the Brazilian Society of Allergy and Immunology prepared an updated document of the 1st Brazilian Consensus, published in 2010. The document presents new knowledge about the indications and efficacy of immunoglobulin therapy in primary immunodeficiencies, relevant production-related aspects, mode of use (routes of administration, pharmacokinetics, doses and intervals), adverse events (major, prevention, treatment and reporting), patient monitoring, presentations available and how to have access to this therapeutic resource in Brazil.

Evaluation of emergency drug releases from the Centers for Disease Control and Prevention Quarantine Stations.

The Centers for Disease Control and Prevention (CDC) Quarantine Stations distribute select lifesaving drug products that are not commercially available or are in limited supply in the United States for emergency treatment of certain health conditions. Following a retrospective analysis of shipment records, the authors estimated an average of 6.66 hours saved per shipment when drug products were distributed from quarantine stations compared to a hypothetical centralized site from CDC headquarters in Atlanta, GA. This evaluation supports the continued use of a decentralized model which leverages CDC's regional presence and maximizes efficiency in the distribution of lifesaving drugs.

Lentinan degradation in the Lentinula edodes fruiting body during postharvest preservation is reduced by downregulation of the exo-ß-1,3-glucanase EXG2.

Lentinan from Lentinula edodes fruiting bodies (shiitake mushrooms) is a valuable ß-glucan for medical purposes based on its anticancer activity and immunomodulating activity. However, lentinan content in fruiting bodies decreases after harvesting and storage due to an increase in glucanase activity. In this study, we downregulated the expression of an exo-ß-1,3-glucanase, exg2, in L. edodes using RNA interference. In the wild-type strain, ß-1,3-glucanase activity in fruiting bodies remarkably increased after harvesting, and 41.7% of the lentinan content was lost after 4 days of preservation. The EXG2 downregulated strain showed significantly lower lentinan degrading activity (60-70% of the wild-type strain) in the fruiting bodies 2-4 days after harvesting. The lentinan content of fresh fruiting bodies was similar in the wild-type and EXG2 downregulated strains, but in the downregulated strain, only 25.4% of the lentinan was lost after 4 days, indicating that downregulation of EXG2 enables keeping the lentinan content high longer.

[Throat disease in the periphery of Europe: the introduction of diphteria antitoxin in Romsdal county]. / Halsesyke i Europas utkant--da difteriantitoksinet kom til Romsdals amt.

Diphteria played a key role in establishing the bacteriological model for explaining infectious disease. This understanding of bacteriological factors spurred research that culminated in the development of diphteria antitoxin, the first effective therapeutic cure for an epidemiological disease. Prior to the introduction of antitoxin, isolation and disinfection were regarded as the key defences against diphteria. The opportunity to combine antitoxin therapy with existing methods for combatting the disease was a key factor for the rapid spread of the antitoxin. Diphteria antitoxin was first used in Romsdal county in 1895. Initially the serum had to be ordered from manufacturers abroad, which restricted its application in the district. Few available doctors and long transport routes were reasons that prevented the antitoxin from reaching its full potential. Industrial manufacturing methods were an obstacle to serum production in peripheral areas. In Norway, production of serum gradually got underway in Kristiania, which was one factor that caused mortality from diphteria to decline faster there than in other parts of the country. In this article we will elucidate the relationship between the centre and the periphery in the spread of medical advances by studying the implementation of diphteria antitoxin in Romsdal county.

The global availability of rabies immune globulin and rabies vaccine in clinics providing indirect care to travelers.

We assessed rabies vaccine (RV) and immune globulin (RIG) availability on the local market by querying US Embassy medical staff worldwide. Of 112 responses, 23% were from West, Central, and East Africa. RV and RIG availability varied by region. Possible rabies exposures accounted for 2% of all travelers' health inquiries.

Unscrupulous marketing of snake bite antivenoms in Africa and Papua New Guinea: choosing the right product--'what's in a name?'.

Snake bite envenoming, mainly caused by the saw-scaled or carpet viper (Echis ocellatus), is a neglected disease of West Africa. Specific antivenoms can save life and limb but, for various reasons, supply of these essential drugs to Africa has dwindled to less than 2% of estimated requirements. Other problems include maldistribution, inadequate conservation and inappropriate clinical use of antivenoms. In the face of this crisis, several promising new antivenoms have been developed. However, some dangerously inappropriate products of Indian origin are being marketed by unscrupulous manufacturers or distributors in Africa and Papua New Guinea, with disastrous results. A major source of confusion is labelling antivenom with ambiguous snake names that fail to distinguish the Asian species whose venoms are used in their production from the local snakes whose venoms are antigenically dissimilar.
