NIDIAG aims to address these issues for NIDIAG aims to improve quality of clinical care for three clinical syndromes: the persistent digestive disor- three common syndromes in the tropics and will provide ders discussed here, along with neurological disorders specific efforts to translate evidence into policy.

Hence, and persistent fever. First, digestive syndromes are associated with cost-effectiveness analyses of integrated algorithms and many different NTDs, particularly helminth and intes- diagnostic platforms compared to single-disease oriented tinal protozoa infections [44], but the magnitude of their laboratory tests; and iii analysis of acceptability and ap- contribution to persistent digestive disorders is largely propriateness of innovative diagnosis-treatment tools for unknown.

A single disease perspective will not be able application in the primary health care settings.

Second, for participating communities. For instance, the Digestive disorders are among the major clinical syn- control of several helminth NTDs currently relies on dromes that characterise a host of NTDs in Africa, Asia, preventive chemotherapy; that is the regular, large-scale Latin America and elsewhere.

The morbidity due to administration of one or several orally available drugs diarrhoeal diseases in low- and middle-income countries with the aim of reducing the parasite load and thus pre- continues to be considerable. While the aetiological venting the development of severe disease [46, 47]. These spectrum of acute diarrhoea has been widely investi- strategies offer opportunities for a rapid impact at low gated, the major pathogens giving rise to persistent diar- cost in resource-constrained settings, especially in areas rhoea and other non-acute digestive disorders remain to where the targeted diseases are highly prevalent.

How- be elucidated [9, 16]. Recently, public health tered clinical syndromes in resource-constrained settings specialists put particular emphasis on integrated control from a patient-centred perspective, rather than relying approaches that go beyond preventive chemotherapy on single disease-oriented approaches.

Indeed, a recent [50, 51]. The disease-specific focus of many NTD control study in Tanzania investigated the causes of fever in chil- programmes has led to fragmentation and gaps in patient dren and brought to light that viral infections predomin- management. At the primary health care level, however, ate and are considerably more common than parasitic nurses and physicians do not deal with a single disease, diseases e.

In contrast to this finding, clini- plaints. Among these clinical syndromes, they have to rec- cians commonly prescribe antimalarial and antibacterial ognise the specific NTDs and discriminate these from a medication in the absence of diagnostic testing facilities, constellation of other illnesses.

Hence, there is a need for which in turn leads to overtreatment with potential evidence-based guidelines on the management of a spe- negative consequences e. It is conceivable that similar miscon- rather than single programmes targeting one of the ceptions and mismanagement apply to other clinical aetiological agents. There is growing consensus that well- syndromes, including persistent diarrhoea and persistent functioning health systems are required to achieve sustain- abdominal pain, which is the focus of the current study able NTD control and improved diagnosis-treatment protocol.

It has been postulated that an improved algorithms are key to this [52, 53]. Furthermore, this study will help to assess the contribution of NTDs to persistent digestive disorders and, subsequently, develop References and evaluate sustainable and cost-effective control pro- 1.
