He lives in a city in the north part of the island of Borneo. He is being managed by a doctor in the Malaysian City of Kuching. Now the doctor caring for this man is married to an Infectious Disease expert and she raises concerns that this might be due to a parasitic disease. She is told by the husband that the disease of which she is thinking is not present in the region. She is not swayed and admits him for nightly blood smears which are negative. She then does a rapid immunochromatographic dipstick test that is positive. He lives in a community outside the city and they go to that village and find others with limb swelling issues who are also positive on antigen testing. He is treated with an antibiotic, not antiparasitic for 4 weeks and the arm improves.  Hint: this is not Wuchereria Bancrofti.

Saint Lucia is taking a major step towards confirming the elimination of schistosomiasis, also known as bilharzia. While the prevalence of the disease is at extremely low levels with only 36 cases recorded in the past decade, the World Health Organization (WHO) requires countries to demonstrate zero cases to confirm elimination status. Therefore, the Ministry of Health, Wellness, and Elderly Affairs has made it a priority to conduct a national survey among primary school students to determine if the country is at the level of elimination. In addition, the ministry is ramping up public education efforts about schistosomiasis.

The Ministry of Health, Wellness, and Elderly Affairs will embark on a nationwide initiative in November to assess the presence of schistosomiasis (bilharzia) among primary school children aged 8 to 11. This initiative aims to detect and address potential cases of this waterborne disease, which is transmitted through contact with contaminated water in rivers, streams, and ponds, where specific snails release the disease-causing eggs. The survey will involve a random sample of students from public primary schools across Saint Lucia. Parents will receive information packages and consent forms with full details about the survey process, and participation is entirely voluntary. To minimize any disruption to academic activities, the survey will be conducted during school hours. By undertaking this initiative, the Ministry aims to take a significant step toward safeguarding the health and well-being of Saint Lucia's youth, ensuring a healthier future for all.

In this episode we will be hearing about a seven year research programme known as COUNTDOWN. COUNTDOWN consisted of multidisciplinary research teams across 4 countries- Ghana, Liberia, Nigeria and Cameroon and used co-production research approaches to improve the equity and efficiency of health systems interventions to control and eliminate seven Neglected Tropical Diseases. Research was implemented at each of the health system levels from policy to community and is all documented in the Journal ‘International Health' as a supplement entitled Stronger together: evidence for collaborative action on neglected tropical diseases. The supplement tells the story of how the programme engaged with people who have lived experience, health workers, and policy makers and really emphasises the importance of togetherness. Our guests today are Dr Luret Lar who was the programme manager employed by Sightsavers Nigeria, a collaborator on the COUNTDOWN programme, Dr Karsor Kollie who is the Program Director for Neglected Tropical Diseases at the Ministry of Health Liberia and Laura Dean from the Liverpool School of Tropical Medicine who was the Social Science lead for COUNTDOWN. Dr Laura Dean – Lecturer, Liverpool School of Tropical MedicineLaura has worked for the last 15 years in the use of participatory health research methodologies to support community and health systems development across sub-Saharan Africa and south Asia. Through participatory action research projects, she supports capacity strengthening within communities and health systems so that stakeholders can identify challenges and co-produce solutions. The majority of her work has focused on increasing inclusion and participation of people with lived experience of mental health conditions and chronic infectious diseases of poverty, for example neglected tropical diseases.Dr. Luret Lar - Medical Doctor, Public Health Physician, Lecturer, University of Jos, NigeriaLuret was involved in implementation research for seven years in collaboration with Liverpool School of Tropical Medicine when she was working for Sightsavers. Her interest and passion about preventive medicine and including the voices of the voiceless have influenced her research career over the years. Luret was interested in inclusivity at all levels of implementation in the neglected tropical diseases programme. This connected her with people affected by neglected tropical diseases and implementers at the community facility, state, and federal levels. She worked closely with these implementers to co-produce solutions to implementation challenges that everyone collectively identified.Karsor Kollie – Programme Director, Ministry of Health, LiberiaSince 2011, Mr Kollie has established and headed the Liberian Integrated NTDs Prevention and Control Programme and is based within the Ministry of Health and Social Welfare. He developed the NTD country master plan which forms the operational national guide for the next 5 years.Under his leadership the Liberian programme is making excellent progress in MDA control of Lymphatic Filariasis, Onchocerciasis, Schistosomiasis, Soil-transmitted Helminthiasis (STH) where treatment coverage has not gone below 75%, respectively. Alongside this, he is making significant progress in the development and application of new monitoring and evaluation criteria tailoring activities effectively with difficult on-the-ground terrain.More information can be found in the special supplement discussed in this episode: Stronger together: evidence for collaborative action on neglected tropical diseases | International Health | Oxford Academic (oup.com)Want to hear more podcasts like...

Parasites may bet a bad rap overall, but they play a vital role in healthy ecosystems. In this episode, we focus on the role parasites play in freshwater ecosystems. Specifically, we're talking about the role of avian schistosomes, a very interesting parasite that infects waterfowl, but that also uses snails as a host in its larval stage. Larvae also infect humans to cause what's know as swimmer's itch.To guide this conversation we have Dr. Patrick Hanington, associate professor in the School of Public Health at the University of Alberta. As a self-described parasitologist and immunologist he and his team focus on developing multiplexed PCR-based tests to detect freshwater parasites, including avian schistosomes. Their work benefits locals in his area by monitoring pubic and recreational waters for swimmer's itch outbreaks, but their work also serves as a model for informing human schistosome research, where Schistosomiasis is the second most prevalent disease worldwide, behind malaria. In our conversation with Patrick we learn about how they design their assays, why they're increasingly using dPCR instead of qPCR. Beyond the technical work, we get into how Patrick's career path developed, how what he loves most about his job has changed and evolved over time, his lessons learned in the lab, and how his research and hobbies have blended over time. And because it's Absolute Gene-ius, you know we keep it fun with some unexpected movie references and a bit of discussion about how science is represented in television and film. Visit the Absolute Gene-ius page to learn more about the guest, the hosts, and the Applied Biosystems QuantStudio Absolute Q Digital PCR System.

This case is of a 24 year old male who presented to the emergency room at the end of February with a 4 day history of fever, starting three weeks after he returned from a long trip. He reports traveling in India during October of the past year. From November to early January, he stayed in Papua New Guinea, from where he traveled to Thailand, returning to Israel in early February. On admission he reports a daily fever up to 40 degrees C, which I think is 104 Fahrenheit. He also mentions an itchy rash and dry cough. We learn a bit more about this patient. In Thailand, he received a five-day course of doxycycline due to a febrile illness, which resolved after treatment. During his stay in Papua New Guinea he hiked in the jungle, was bitten by multiple insects and also report finding leeches attached to his lower legs. One insect bite on his hip took a while to heal. He also reports swimming in multiple rivers. While travelling, he did not have unprotected sexual encounters but he admits to eating street food and home made food regularly. He received pre-travel vaccines and when he was in Papua New Guinea took Atovaquone Proguanil prophylaxis daily, discontinuing therapy a week after he flew to Thailand. On physical exam he is alert and oriented, vitals normal, the examination is unremarkable except for three cropped vesicles on his penis, which the patients says are itchy. A healed insect bite on his lower hip is also noted. His white blood count and differential are normal without eosinophilia. His haemoglobin is 13 g/dl, which is borderline normal and his platelet count is lower than normal with a count of 100,000 per microlitre of blood. What is your diagnosis?

Some diseases are spread almost exclusively by touch or through the skin or mucus membranes. These include Ebola, several parasitic diseases such as hookworm, strongyloides and scabies and some bacterial and fungal infections. Other diseases like COVID-19 and influenza are mainly transmitted via other routes but use touch as a secondary method of spread. This has implications for controlling these diseases, including the role of isolation and sanitation.A lecture by Chris WhittyThe transcript and downloadable versions of the lecture are available from the Gresham College website:https://www.gresham.ac.uk/lectures-and-events/touch-infectionsGresham College has been giving free public lectures since 1597.

Peter Hotez talks about the global impact and historical context of neglected tropical diseases. He also highlights important developments in mass drug administration and vaccine research and shares why he chose to publish the third edition of Forgotten People, Forgotten Diseases during the COVID-19 pandemic. Ashley's Biggest Takeaways Neglected Tropical Diseases (NTDs) are chronic and debilitating conditions that disproportionately impact people in low- and middle-income countries (LMICs).  Many of these diseases are parasitic, such as hookworm infection, schistosomiasis and chagas disease; however, in recent years, several non-parasitic infections caused by bacteria, fungi and viruses, as well as a few conditions that are not infections, including snake bite and scabies (an ectoparasitic infestation), have been added to the original NTD framework (established in the early 2000s).  What do most NTDs have in common? High prevalence. High mortality; low morbidity. Disabling. Interfere with people's ability to work productively.  Impact child development and/or the health of girls and women. Occur in a setting of poverty and actually cause poverty because of chronic and debilitating effects. Hotez and his colleagues recognized that there is a uniqueness to the NTDs ecosystem, and they began putting together a package of medicines that could be given on a yearly or twice per year basis, using a strategy called Mass Drug Administration (MDA). This involved the identification of medicines that were being used on an annual basis in vertical control programs and combining those medications in a package of interventions that costs about $0.50 per person per year. “Throw in an extra 50 cents per person and we could double or triple the impact of public health interventions,” he explained.   Emerging diseases, such as SARS-CoV-2, capture the attention of the public for obvious reasons. They pose an imminent threat to mankind. NTDs are not emerging infections, but they are ancient afflictions that have plagued humankind for centuries and, as a consequence, have had a huge impact on ancient and modern history. One of the reasons we have mainland China and Taiwan today may have been, in part, due to a parasitic infection, Schistosomiasis. Hotez and colleagues at the Texas Children's Center for Vaccine Development have developed a COVID-19 vaccine, based on simple technology, similar to what is used for the Hepatitis B vaccine. They hope to release the vaccine for emergency use in resource poor countries like India and Indonesia.  When asked about the timing of the publication of his book, the third edition of Forgotten People, Forgotten Diseases, Hotez acknowledged the difficulty of helping countries understand that NTDs have not gone away. COVID-19 is superimposed on top of them, and the pandemic has done a lot of damage in terms of NTD control. Although social disruption has interfered with the ability to deliver mass treatments, Hotez said that it has been gratifying to see that the USAID and their contractors have responded by putting out guidelines about how to deliver mass treatments with safe social distancing. “As a global society, we have to figure out how to walk and chew gum at the same time,” he said. “We've got to take care of COVID, but we really must not lose the momentum we've had for NTDs because the prevalence is starting to decline and we're really starting to make an impact.”

TTE: Positive bubble study Episode Teaching Pearls Pulmonary hypertension (PH) can generally be categorized as pre-, post-, or combined pre- and post-capillary PH. Isolated pre-capillary pulmonary hypertension is characterized by: mean pulmonary artery pressure (mPAP) ≥ 20 mmHg, a pulmonary capillary wedge pressure (PCWP) ≤ 15 mmHg, and a pulmonary vascular resistance (PVR) ≥ 3 Woods units (WU). Pulmonary arterial hypertension (PAH) (WHO Group 1) falls under pre-capillary pulmonary hypertension.Schistosomiasis is the most common cause of PAH (WHO Group I) worldwide. Approximately 7% of patient with hepatosplenic schistosomiasis have PAH. Some studies suggest that treatment of with praziquantel reverses vascular remodeling; however, there is point of no return, beyond which, anthelmintic therapies are ineffective to prevent progression.Exertional syncope and pericardial effusion are both risk factors for higher mortality in PAH.Women with severe PAH have extremely high risk of maternal morbidity and mortality. Endothelin receptor antagonists are contraindicated in pregnancy due to teratogenicity. Therefore, a pregnancy test must be obtained monthly while on this therapy.Patients with a lower socioeconomic status, based on median household income, have more advanced PAH at the time of diagnosis. Notes 1. How do you approach syncope? Syncope is a sudden transient loss of consciousness associated with absence of postural tone followed by complete and usually rapid recovery. There should be not be clinical evidence of “non-syncope” conditions including seizures, hypoglycemia, drug or alcohol intoxication, concussion due to head trauma and so forth. One approach to determining the etiology of the syncope is to consider 4 major categories: orthostatic, reflex-mediated, cardiac-obstructive,

Winka Le Clec'h, Ph.D., Tim Anderson, Ph.D., and Frederic Chevalier research schistosomiasis at Texas Biomed. Schistosomiasis is an important tropical disease caused by schistosome trematodes (a parasitic blood fluke). Those parasites are found in South America and the Caribbean, sub-Saharan Africa, the Middle East, and Southeast Asia. An estimated 200 million people worldwide are infected with schistosomes and 200,000 people die each year. Schistosomiasis is a waterborne disease. Infected freshwater snails release larvae (cercariae) which can infect humans during their water related activities.   Only one drug – praziquantel – is currently available to treat patients but drug resistance starts to emerge. Vaccines have been designed in laboratory but have never conferred decent level of protection to people in the field. Therefore new approaches are needed to identify drug targets, understand drug resistance, predict vaccine efficacy by understanding parasite population diversity and identify potential vaccine candidates. More than 6,000 snails used for research are housed at Texas Biomed. The Texas Biomed schistosomiasis lab has pioneered the use of genetic crosses between schistosomes in the laboratory for identifying the genetic basis of biomedically important parasite traits. Scientists have used this approach, together with exome sequencing, to identify the precise mutations that underlie oxamniquine resistance, and are now applying the same approach to understand praziquantel resistance, host specificity, parasite virulence, and multiple other important biomedical traits. High speed data processing in the Genomics Computing Center make this research possible.

Die epidemiologischen Daten zeigen eine eindeutige Zuordnung von Schistosomiasis und Filariosen auf den afrikanischen Kontinent, während die Geohelminthiasen (Erkrankungen durch Helminthen, deren präadulte Stadien sich im Erdboden entwickeln und die eine reise- bzw. migationsmedizinisch wichtige Bedeutung haben) von den Reiserückkehrern vorwiegend in Asien, vorzugsweise in Südostasien, akquiriert wurden. Die Migranten stammten hauptanteilig aus Afrika, es waren dennoch alle wesentlichen tropischen und subtropischen Gebiete vertreten. Die Auswertung der klinischen Symptomatik zeigte ein klares Erscheinungsbild der Filariosen mit Hauterscheinungen und Juckreiz sowie die überdurchschnittlich häufige Angabe von Harnwegsbeschwerden bei Infektionen mit Schistosoma haematobium. Bei allen Geohelminthosen und Infektionen mit Schistosoma mansoni herrschte bei den Reiserückkehrern eine gastrointestinale Symptomatik vor, während die Migranten insgesamt mehr unspezifische Beschwerden aufwiesen. Circa ein Drittel der Patienten war asymptomatisch. Die Sensitivität der Eosinophilie als indirekter Parameter lag in dieser Arbeit für Wurmerkrankungen im Allgemeinen bei 45%, variierte aber von Diagnose zu Diagnose erheblich, wobei kein signifikanter Unterschied zwischen Reiserückkehrern und Migranten zu finden war. Eine Hypereosinophilie fand sich überdurchschnittlich häufig bei Migranten mit Filariose und bei Reiserückkehrern mit Strongyloidiasis; die Patienten mit Askariasis und Trichuriasis zeigten dagegen kaum Abweichungen von der Kontrollgruppe. Eine Gesamt-IgE-Erhöhung fand sich insgesamt bei 43% der Patienten, wobei es einen signifikanten Unterschied zwischen Reiserückkehrern (25%) und Migranten (75%) gab. Besonders hohe IgE-Serumspiegel konnten bei Migranten mit Schistosomiasis, Strongyloidiasis und Ankylostomiasis gefunden werden. Davon abweichend waren allerdings die Resultate von Reiserückkehrern mit Mischinfektionen. Bei diesen Patienten konnte eine unerwartet häufige Gesamt-IgE-Erhöhung verzeichnet werden (75%). Die serologischen Untersuchungen zeigten zumeist eine gute Sensitivität, aber erhebliche Kreuzreaktionen mit verwandten und nicht verwandten Wurmarten, sodass eine Differenzierung nur für die Schistosomiasis und die Filariosen valide gewährleistet ist. Der im Rahmen dieser Arbeit entwickelte Ascaris suum-ELISA, ergab eine Sensitivität von 60% und eine Spezifität von 90% und hat in der Routinediagnostik eine gewisse Berechtigung, da der Ascaris lumbricoides-ELISA inakzeptable Ergebnisse erbrachte. Zusammengefasst stellt die Eosinophilie einen wichtigen hinweisenden Parameter auf eine Wurminfektion dar, ist aber keine ausreichende Screeningmethode bei Rückkehr aus Endemiegebieten. Die serologischen Untersuchungen ergaben eine sinnvolle diagnostische Ergänzung bei der Schistosomiasis und den Filariosen. Eine Differenzierung der Geohelminthosen ist weiterhin nur durch direkte Nachweismethoden, wie z. B. dem Ei- bzw. Larvennachweis im Stuhl oder in einem Körpergewebe, verlässlich möglich.

In den letzten Jahrzehnten haben sich Reisetätigkeit und Migration zu wichtigen Faktoren für die Ausbreitung von Infektionskrankheiten entwickelt. Allein im Jahr 2011 fanden über 980 Mio. internationale Reisen statt, wobei etwa 50 Mio. Menschen aus industrialisierten Ländern in die Tropen und Subtropen reisten. Ökologische und sozioökonomische Veränderungen, bedingt durch eine wachsende Weltbevölkerung und eine globalisierte Wirtschaft, und der technische Fortschritt beim Transport werden diesen internationalen Personenaustausch und damit die Ausbreitung von Infektionskrankheiten weiter fördern. Um dieser Entwicklung Rechnung zu tragen, wurde die Reisemedizin als eigene Fachrichtung der Medizin mit dem Ziel etabliert, durch international gültige Regelungen reiseassoziierte Infektionskrankheiten zu bekämpfen. Doch vor allem die epidemiologischen Gesundheitsdaten bezüglich der importierten Infektionskrankheiten bei Kindern und Jugendlichen sind limitiert, was insofern ein Problem ist, weil Kinder und Jugendliche bei Reisen häufig von einem anderen Erregerspektrum als Erwachsene betroffen sind und einen im Vergleich zu Erwachsenen unterschiedlichen Krankheitsverlauf bei Infektionen zeigen. Deswegen hat sich diese Dissertation das Ziel gesetzt, die reisemedizinische Beratung von Kindern und Jugendlichen bzw. ihrer Erziehungsberechtigten vor der Reise als auch die diagnostischen Abläufe zum Erkennen der importierten Infektionskrankheit nach der Reise auf eine evidenzbasiertere Grundlage zu stellen. Um evidenzbasierte Empfehlungen zu geben, bedient sich diese Dissertation Methoden der deskriptiven und der analytischen Epidemiologie. Dazu wurden in der Abteilung für Infektions- und Tropenmedizin der Ludwig-Maximilians-Universität München innerhalb des Zeitraums von Januar 1999 bis Dezember 2009 Daten von 890 Reisenden im Alter von unter 20 Jahren, welche aus den Tropen oder Subtropen zurückgekehrt waren, gesammelt und wichtige klinische (z.B. Symptome) und diagnostische (z.B. Laborparameter) Variablen (abhängige Variablen) bezüglich importierter Infektionskrankheiten beschrieben, analysiert und interpretiert. Darauf aufbauend wurde die Auswirkung von Risikofaktoren bzw. protektiven Faktoren (unabhängige Variablen), welche sich in sozio-demographische Daten (z.B. Geschlecht, Alter, Herkunft) und Reisedaten (z.B. Reiseziel, Reisedauer, Reiseart) aufteilen, auf die abhängigen Variablen analysiert. Diese Analyse ergab, dass von allen in dieser Studie untersuchten Variablen Reiseziel und Patientenalter diejenigen Variablen waren, die am stärksten mit dem Risiko korrelierten, an einer für die Tropen und Subtropen typischen oder spezifischen Infektionskrankheit zu erkranken. Bezüglich der Variable Alter zeigte sich, dass Reisende älter als neun Jahre eine ähnliche Verteilung der Krankheitshäufigkeiten wie Erwachsene aufweisen. Mit zunehmendem Alter unternahmen Reisende häufiger Rucksackreisen und infizierten sich öfter mit Mononukleose, was die wachsende Bedeutung der Reise als Unterhaltung und Selbsterfahrung, insbesondere bei Jugendlichen, unterstreicht. Im Gegensatz dazu präsentierten Kinder unter zehn Jahren ein von den Erwachsenen abweichendes Verteilungsmuster der Infektionskrankheiten. So hatten sehr junge Reisende ein erhöhtes Risiko für Durchfall- und Hauterkrankungen während der Reise. Deshalb sollten junge Reisende oder ihre Erziehungsberechtigten vor Reiseantritt über die Präventionsmaßnahmen und mögliche Laientherapie dieser beiden Syndromgruppen aufgeklärt werden bzw. darüber, bei welcher Symptomkonstellation ein Arztbesuch anzuraten ist. Zudem reisten sehr junge Menschen länger und besuchten häufiger Freunde und Familie. Die längere Reisedauer wiederum war verbunden mit einer relativen Zunahme von spezifischen importierten Infektionskrankheiten. Deswegen sollte bei Patienten, die sich länger in tropischen und subtropischen Regionen aufgehalten haben und nach anamnestischen und klinischen Kriterien einer spezifischen Diagnostik und Therapie bedürfen, an diese Erreger gedacht werden. Dagegen kann von einer derartigen spezifischen Diagnostik bei Patienten mit kurzer Reisedauer abgesehen werden, da eine Durchfallsymptomatik bei diesen meist durch akute Durchfallerkrankungen bedingt ist, die nur einer symptomatischen Therapie bedürfen. Aufgrund der begrenzten geografischen Verteilung bestimmter Infektionserreger stellte die Variable Reiseziel einen wichtigen Risikofaktor für das Auftreten von den durch diese Erreger verursachten Erkrankungen dar. Dies verdinglicht noch einmal die Notwendigkeit, Patienten im Beratungsgespräch vor Reiseantritt auf das sie erwartende landesspezifische Erregerspektrum vorzubereiten und die für ebendiese Erreger geeigneten Präventionsmaßnahmen durchzuführen. Dies bedeutet, dass bei Reisen nach Lateinamerika der Schwerpunkt auf Aufklärung über und Prävention von Hautkrankheiten im Allgemeinen und Larva migrans cutanea im Speziellen gelegt werden sollte. Dagegen sollte bei Afrikareisenden auf Schistosomiasis und bei Asienreisenden auf Campylobacteriose und Dengue-Fieber hingewiesen werden. Das höchste relative Risiko, überhaupt zu erkranken, trugen junge Reisende, die sich in Zentral-, West- und Ostafrika aufhielten, gefolgt von Reisenden in Südamerika und Süd-/ Südostasien. Während bei Kindern und Jugendlichen, die eine andere Herkunft als die deutsche hatten, die Variable Herkunft signifikant mit bestimmten importierten Infektionskrankheiten korrelierte, wurde bei den Reisenden deutscher Herkunft, die als Reiseart Besuch bei Freunden und Verwandten angaben, also mit hoher Wahrscheinlichkeit Kinder von Immigranten aus tropischen und subtropischen Ländern sind, keine derartige Korrelation gefunden. Dies legt nahe, dass die Diagnostik und Therapie bei Reiserückkehrer mit Migrationshintergrund nur dann von der von Menschen ohne Migrationshintergrund abweichen sollte, wenn diese eine eigene Migrationserfahrung haben, nicht aber, wenn sie in Deutschland geboren wurden. Das Spektrum der mit Regelmäßigkeit erfassten Symptome bei der Studienpopulation war relativ schmal. Jeweils über ein Fünftel der Patienten stellte sich mit Diarrhö, Müdigkeit, Fieber und Hauterscheinungen vor und insgesamt kamen nur sieben Symptome bei mehr als 10% der Patienten vor; Durchfallerkrankungen, systemische Fiebererkrankungen und Hauterkrankungen machten über 60% der 823 gestellten Diagnosen aus. Dabei waren Durchfallerkrankungen sowohl bei dem Symptom Durchfall als auch bei dem Symptom Fieber wichtigster Auslöser mit Giardia, Campylobacter, und Salmonella als den am häufigsten identifizierten speziellen Infektionserregern. Da Fieber vor allem bei sehr jungen Menschen nicht vorwiegend durch eine als systemische Fiebererkrankung klassifizierte Krankheit bedingt war, ist es umso wichtiger, nicht von bestimmten Symptomen auf Krankheitsentitäten zu schließen, sondern vor einer speziellen Diagnostik durch eine ausführliche Anamnese und klinische Untersuchung weitere Risikofaktoren zu erfassen, um die Krankheit so besser eingrenzen zu können. Insgesamt ließen sich wenige spezifische ätiologische Diagnosen stellen, so dass nur elf Infektionskrankheiten jeweils bei mehr als 1% der Patienten nachzuweisen waren. Besonders gilt dies für die Patienten mit Diarrhö, bei denen 40% mit einer unspezifischen Gastroenteritis diagnostiziert wurden. Die Symptome Fieber, Müdigkeit und Kopfschmerzen stellten für das Patientenkollektiv offensichtlich eine stärkere Belastung dar als andere Symptome, so dass sie schon nach einer signifikant kürzeren Beschwerdedauer einen Arzt konsultierten. Um die Gültigkeit und Anwendbarkeit der vorausgegangen Empfehlungen einschätzen zu können, sollte man die folgenden Limitationen dieser Studie beachten. Die untersuchte Studienpopulation ist wahrscheinlich nicht repräsentativ für alle Reiserückkehrer nach Deutschland, die die von dieser Studie gestellten Einschlusskriterien erfüllen. Gleiches gilt für das Spektrum der Symptome und Erkrankungen, mit denen sich diese Studienpopulation im AITM vorstellte. Es ist anzunehmen, dass viele leichte und selbstlimitierende Verläufe von importierten Infektionskrankheiten an anderen Institutionen behandelt wurden. Ebenso unterrepräsentiert sind Erkrankungen mit einer kurzen Inkubationszeit oder einer unspezifischen Symptomatik, da die Assoziation mit Reise nicht erfolgt. Zwar ist es möglich, aus den untersuchten Daten und Statistiken über Reiseaktivität das relative Erkrankungsrisiko importierter Infektionskrankheiten abzuschätzen, aber es ist nicht möglich, deren Inzidenz zu berechnen. Durch die Einteilung von Krankheiten in Syndromgruppen wurde versucht, eine Konsistenz und Vergleichbarkeit mit vorausgegangenen Studien herzustellen. Gleichzeitig führt dieses Vorgehen aber auch zu einer artifiziellen Homogenisierung, die zu falschen Schlussfolgerungen für spezifische Krankheiten innerhalb dieser Syndromgruppen führen kann. Entsprechendes gilt für alle in dieser Studie verwendeten Variablen, die, um eine für die statistische Auswertung genügend große Patientenanzahl zu erhalten oder um der Vergleichbarkeit halber Referenzwerte einzuhalten, skaliert werden mussten. Dies ist bei nominalskalierten Variablen (z.B. Geschlecht) problemlos möglich, führt aber bei kardinalskalierten Variablen (z.B. Alter) durch das Setzen bestimmter Grenzwerte (z.B. Altersgruppe 0-4 Jahre) automatisch zu Ungenauigkeiten und Verschleierung von Korrelationen (z.B. zwischen Altersgrupe 3-7 Jahre und einer anderen Variablen). Zudem bedingt der Versuch, die Störfaktoren durch Einschlusskriterien gering zu halten, gleichzeitig, dass Personengruppe, für welche die Ergebnisse anwendbar sind, schrumpft. Die geschilderten Probleme betreffen nicht nur diese Dissertation sondern alle in dieser Studie zitierten Publikationen, die sich mit einem ähnlichen Thema beschäftigt haben. Dies liegt daran, dass einerseits Daten über erkrankte Reiserückkehrer nicht zentral nach einheitlichen Kriterien gesammelt werden, sondern in den unterschiedlichen Institutionen eigenständige Prozeduren zur Datensammlung stattfinden und dass andererseits die Übermittlung dieser Daten an ein zentrales Institut nicht von allen erkrankten Reiserückkehrern erfolgt. Um in der Lage zu sein, standardisierte evidenzbasierte Empfehlungen für die Diagnostik und Therapie zu geben, muss zuerst die Datenakquirierung und Datenanalyse standardisiert werden.

Background: Acute schistosomiasis constitutes a rare but serious condition in individuals experiencing their first prepatent Schistosoma infection. To circumvent costly and time-consuming diagnostics, an early and rapid diagnosis is required. So far, classic diagnostic tools such as parasite microscopy or serology lack considerable sensitivity at this early stage of Schistosoma infection. To validate the use of a blood based real-time polymerase chain reaction (PCR) test for the detection of Schistosoma DNA in patients with acute schistosomiasis who acquired their infection in various endemic regions we conducted a European-wide prospective study in 11 centres specialized in travel medicine and tropical medicine. Methods: Patients with a history of recent travelling to schistosomiasis endemic regions and freshwater contacts, an episode of fever (body temperature >= 38.5 degrees C) and an absolute or relative eosinophil count of >= 700/mu l or 10%, were eligible for participation. PCR testing with DNA extracted from serum was compared with results from serology and microscopy. Results: Of the 38 patients with acute schistosomiasis included into the study, PCR detected Schistosoma DNA in 35 patients at initial presentation (sensitivity 92%). In contrast, sensitivity of serology (enzyme immunoassay and/or immunofluorescence assay) or parasite microscopy was only 70% and 24%, respectively. Conclusion: For the early diagnosis of acute schistosomiasis, real-time PCR for the detection of schistosoma DNA in serum is more sensitive than classic diagnostic tools such as serology or microscopy, irrespective of the region of infection. Generalization of the results to all Schistosoma species may be difficult as in the study presented here only eggs of S. mansoni were detected by microscopy. A minimum amount of two millilitre of serum is required for sufficient diagnostic accuracy.

PHILADELPHIA—Scientists in the UK and Uganda have now completed a three year study showing that young children are at continued risk of intestinal schistosomiasis — also known as bilharzia — between the ages of 6-months and five years. In fact, these children should be treated routinely with the anthelminthic praziquantel, just as in older children and adults, for it is proven both safe and efficacious. The Schistosomiasis In Mothers and Infants (SIMI) study was conducted by the Liverpool School of Tropical Medicine and the London School of Hygiene & Tropical Medicine working with the Vector Control Division, Ministry of Health, in Uganda and was reported at the American Society of Tropical Medicine and Hygiene annual conference in Philadelphia. Professor Russell Stothard discussed some of the key findings with Peter Goodwin.

Ectopic late cutaneous schistosomiasis is usually preceded or accompanied by visceral schistosomiasis infection. Our patient presented the very rare case of late cutaneous schistosomiasis as an isolated skin manifestation. Perigenital lesions occurred 1 year after contact with infested water. Identification of the few eggs remaining in the late lesion among the dense cellular infiltrate was difficult. Electron-microscopic studies clearly demonstrated the characteristic eggshell ultrastructure. Copyright (C) 2000 S. Karger AG, Basel.
