Estudio clínico patológico A propósito de un caso clínico Andy Durham BSc. If the causal factors of laminitis are not identified and controlled then clearly it is inevitable that recurrences will happen most likely leading eventually to structural damage to the foot which may become irreversible.

Causation of laminitis in a clinical and experimental setting can essentially be divided into 3 categories: inflammatory, endocrinopathic and excess weight bearing. This latter category, although well recognised, is not frequently encountered and has had little research-based attention. It is well recognised clinically that if horses bear excessive weight on one limb without rest or relief then laminitis may follow presumably via ischaemic and hypoxaemic mechanisms.

This is generally seen when horses choose to bear weight unevenly due to a fracture or severely painful condition affecting the contralateral limb. Thus, from a general aetiologic perspective the 2 main subcategories of laminitis comprise inflammatory and endocrinopathic mechanisms. These include problems such as retained foetal membranes, intestinal strangulations e. Additionally it has been found that enteral dosing of black walnut shavings also predictably results in laminitis.

Again, the precise causal what does sos mean in english is not known although this form of laminitis is associated with a significant inflammatory process also. Laminitis also occurs predictably following exogenous insulin administration and also, less predictably, following exogenous glucocorticoid administration. Collectively these conditions represent endocrinopathic laminitis and this appears to develop in the absence of a notable systemic inflammatory response.

There are essentially 2 types of laminitis! Type 1 can be seen in any individual of any breed or type or age or activity — whether this is a fat native pony or a young, lean and fit What is a non conventional relationship. Examples include problems such as feeding accidents, retained foetal membranes, colitis, etc… i. Type 2 is laminitis that is seen almost exclusively in certain identifiable and susceptible individuals e.

In considering the pathophysiology of laminitis in endocrinopathic cases, our focus has been drawn to the commonly shared feature of insulin resistance IR in such individuals. However, IR tends to be associated with the further components of hyperinsulinaemia and hyperglycaemia which might also be of pathogenic importance Fig 1. This might simply be from down-regulation of insulin receptors in the face of high circulating plasma insulin concentrations.

Theory of disease causation ppt it may be that a primary inherent genetically determined tendency towards hyperinsulinaemia in certain individuals promotes obesity via the known anabolic effects of insulin on adipose tissue, and this developing obesity then leads to secondary tissue IR. The 3rd related component of hyperglycaemia may result from glucose intolerance as tissue insulin insensitivity fails to promote normal tissue uptake of glucose from plasma into insulin-sensitive tissues.

Should hyperglycaemia develop then this will tend to further stimulate secondary hyperinsulinaemia. Thus, the 3 components of tissue IR, hyperinsulinaemia and hyperglycaemia are closely inter-related, but are not synonymous or even always coexistent. The concept of a primary tendency towards either IR or hyperinsulinaemia makes sense in evolutionary terms. Many breeds known to be prone to laminitis evolved in nutritionally sparse what is the difference between primary producers and consumers where food supply may have been both poor and inconsistently available.

Evolutionary development of relative resistance to the effects of insulin would have the metabolic advantages of prioritisation and preservation of glucose for non- insulin dependent tissues such as the brain, kidneys, heart and laminae, and additionally the capacity to more rapidly mobilise glycogen and adipose stores when feed becomes unavailable eg. Evolutionary development of a tendency towards hyperinsulinaemia is also logical. In harsh theory of disease causation ppt ingestion of significant amounts of nutrients that stimulate insulin secretion such as glucose would be a relatively rare event.

Theory of disease causation ppt such circumstances individuals may have developed a relatively decreased beta-cell threshold for glucose-induced insulin secretion otherwise insulin would never be secreted! Figure 1. Schematic demonstrating the possible interrelationships of what is genetic testing for thyroid cancer resistance, hyperinsulinaemia and hyperglycaemia.

It is known that the laminae have an exceptional requirement what is a qualitative research design glucose Wattle and Pollitt and, should insulin fail to promote normal cellular uptake of glucose then laminar failure might follow Pass et al However this theoretical explanation appears unlikely given that laminar does gene flow increase genetic variation cells have been found not to express GLUT4, the main insulin-dependent glucose transporter.

Rather, these cells are found to express GLUT1 which represents a transporter whereby plasma glucose is taken into laminar cells without the involvement or requirement for insulin. In humans with metabolic syndrome, hyperglycaemia is considered to be an important pathogenic factor. However, it is immediately doubtful that this is of importance in horses with EMS or PPID given that resting hyperglycaemia is uncommon in contrast theory of disease causation ppt humans.

Additionally studies have failed to demonstrate markers of glucotoxicity such as advanced glycation end products AGEs during development of hyperinsulinaemic laminitis de Laat et al a. Currently the only successful experimental model of endocrinopathic theory of disease causation ppt involves hyperinsulinaemia. Subsequently de Laat et al found the same model to be similarly effective in triggering laminitis in insulin sensitive Standardbred horses.

A further study by de How to calm down in a relationship et al b attempted to investigate the possible relevance of hyperglycaemia by infusing glucose at the same rate as used in the HEC, but without exogenous insulin. Collectively these studies suggested that hyperinsulinaemia was the primary mechanism for development of laminitis and that hyperglycaemia, if relevant, was of more minor importance.

As none of the horses and ponies in the above studies had IR, this also did not appear necessary for development of laminitis. Although hyperinsulinaemia appears to be the most likely trigger factor for endocrine laminitis, the pathogenetic relevance of IR and hyperglycaemia cannot be entirely discounted even if from indirect influences on promoting hyperinsulinaemia. The putative mechanism by which hyperinsulinaemia might trigger laminitis is not fully understood although several possibilities exist.

Although, as mentioned above, laminar epithelial cells are not responsive or dependent on insulin, this is theory of disease causation ppt the case for digital blood vessels which do possess insulin receptors and responsiveness to insulin. Insulin is a vasoactive hormone which may provoke either nitric oxide mediated vasodilation or endothelin-mediated vasoconstriction through differing intracellular pathways PI3 kinase and MAP kinase pathways respectively.

Equine studies have demonstrated that vascular ring preparations exposed to insulin for as little as 30 minutes became vasoconstricted in response to further exposure to insulin, in marked contrast to the vasodilation occurring in control vessels without prior insulin exposure Venugopal et al Apart from possible vascular effects, insulin might also mediate dysregulation of cellular growth and differentiation. Hyperinsulinaemic laminitis is noted to be associated with apparent elongation of epidermal lamellae and also increased apoptosis and considerable mitotic activity of laminar epithelial cells.

These changes in lamellar cellular activity may well be relevant to laminitis development and could be mediated via insulin like growth factor-1 receptors which, unlike insulin receptors, are indeed present on laminar epithelial cells. It is possible that all forms of endocrinopathic laminitis share the same pathogenetic pathway in development of laminitis and a tendency towards excessive hyperinsulinaemia is a feature of phenotypic EMS cases, PPID and exogenous glucocorticoid administration.

It is well recognised that certain identifiable individuals are more likely to develop laminitis than others and it is interesting to observe how this individual laminitis-predisposition corresponds to insulin dynamics. Several studies have indicated that hyperinsulinaemic responses to glucose feeding are very different in certain individuals. Ponies have been shown to theory of disease causation ppt far greater hyperinsulinaemic responses to glucose ingestion than horses Tinworth et aland, furthermore, laminitis-prone ponies demonstrate far higher insulinaemic responses to glucose, fructose or fructan ingestion than non-laminitic ponies Bailey et al ; Borer et al It is tempting to speculate that this inherent tendency towards an excessive insulinaemic response mimics events that occur following consumption of non-structural carbohydrate-rich pasture.

Thus it is hyperinsulinaemia, rather than IR, that is most deserving of our focus with respect to diagnostic testing for a laminitis predisposition and also for treatment and management procedures to target for control. Although hypercortisolaemia has been previously considered as a pathogenetic mechanism explaining laminitis in PPID cases, this may well have arisen following confusion and lack of distinction between PPID and analogous conditions in other species that result in pituitary-dependent hyperadrenocorticism.

However, there is little if any evidence to support the coexistence of PPID with hyperadrenocorticism or hypercortisolaemia in horses. Adrenal hypertrophy is reported to be relatively rarely in PPID cases, most likely due to the observation that the increased measured plasma ACTH concentrations in PPID cases does not appear to possess normal bioactivity. Furthermore, plasma cortisol concentrations in PPID cases are indistinguishable from those of normal horses.

In contrast to the lack of scientific support for hypercortisolaemia as a cause of laminitis in PPID, the evidence for involvement of hyperinsulinaemia is compelling. Additionally Walsh et al demonstrated an association between plasma insulin levels and grade of laminitis. Hence, it is plausible that hyperinsulinaemia is a common pathogenic pathway important in development of laminitis in both EMS and PPID cases. In EMS cases this hyperinsulinaemic response may derive from a genetic predisposition towards exaggerated pancreatic secretion possibly augmented by tissue IR resulting from obesity.

In PPID cases the hyperinsulinaemic response is less clearly explicable although the pars intermedia is known to produce peptides known to be insulin secretagogues such as beta cell tropin and this might provide an explanation for the hyperinsulinaemia seen in non-obese PPID cases. Pasture grazing or excess cereal ingestion is a very common event preceding numerous laminitis cases seen in practice and it is interesting to speculate just how consumption of grass might lead to laminitis and how this fits with our understanding of inflammatory and endocrinopathic laminitis.

Pathogenetic focus has inevitably fallen on the non-structural carbohydrate NSC component simple sugars, starches and fructans within grass as the likely provocateur of laminitis although this is not known for sure. Nevertheless it is interesting to speculate how grass NSC might feasibly trigger laminitis. In the context of inflammatory laminitis it is might be argued that the large and indigestible fructan component of NSC in temperate grass species passes through the upper GI tract and arrives in the colon where bacterial hydrolysis results in acidosis and barrier dysfunction as is seen in carbohydrate overload models of laminitis.

In the context of naturally occurring pasture-induced laminitis it is then interesting to speculate how much NSC a grazing pony could feasibly consume and how this relates to the supposed pathogenic thresholds above. In contrast, an hourly intake of 0. Interestingly it would appear that a similarly excessive hyperinsulinaemic response may also be provoked by exogenous glucocorticoids French et al ; Tiley et alagain in certain predisposed individuals Bailey et al Thus laminitis may be either an endocrine or an inflammatory disease, or it may be neither and result from laminar ischaemia secondary to excessive weight bearing.

However there is compelling evidence that laminitis is triggered most commonly by hyperinsulinaemia.
