Diagnostic Alternatives for Mycobacterium paratuberculosis in Domestic Ruminants: “Well, Nobody’s Perfect” (Some Like It Hot, 1959)

Abstract

The knowledge of the prevalence of an infection of such a microorganism as MAP (Mycobacterium avium subsp. paratuberculosis)- considering its very precise individualities, is the key issue when deciding which control measures to apply, in the precise individualities of a geographic region. The absence of scientific-based information about the prevalence of bovine paratuberculosis (PTB) could restrict the possibilities of systematic interventions for a problem already confirmed and known by the sanitary authorities, but without information on prevalence, epidemiology, and impact or economical losses, such confirmation is worthless. For the antemortem diagnosis of PTB in domestic ruminants, an important number of testing alternatives are available and recommended, including those used to detect MAP-cellular response, specific antibodies, MAP genes, and even only MAP growth. In this sense, the sensitivity and specificity of such tests vary significantly depending on the infection stage and inherent characteristics of the methods. In this reviewing appraisal, the advantages and disadvantages of currently available MAP diagnostic alternatives are revised, with the firm intention of proposing a response to a changing biological and methodological reality.

Mini Review

The knowledge of the prevalence of an infection of such a microorganism as MAP (Mycobacterium avium subsp. paratuberculosis) - considering its very precise features, is the key issue when deciding which control measures to apply, in the also precise individualities of a geographic region. The absence of scientific-based information about the prevalence of bovine paratuberculosis (PTB) could restrict the possibilities of systematic interventions for a problem already confirmed and known by the sanitary authorities, but without information on prevalence, epidemiology, and impact or economical losses, such confirmation is worthless. Since the epidemiological information on this disease is still scarce, the economic impact on dairy health and production will remain uncalculated, and the potential zoonotic risk unattended, which is of main concern for all industrialized and non-industrialized countries.

An important number of testing alternatives are available and recommended for the antemortem diagnosis of PTB in domestic ruminants, including those aiming to detect anti-MAP immune cellular response and antibodies, MAP genes, or the bacteria itself on different matrices [1-4]. The test´s sensitivity and specificity vary depending on the infection phase and inherent characteristics of the tests [5].

On the first front of diagnostic alternatives are those based on the early immune response to MAP infection consists primarily of a cellular response characterized by the secretion of interferon (IFN)-γ [6-8], almost exclusively in those animals moving into stage II of the disease (this is, inapparent carrier adults), also presenting high MAP concentrations in their intestinal tissues [9]. Contrary to what one would think, such animals do not manifest weight loss or diarrhea even with increased IFN-γ production by sensitized T cells pointing to specific mitogens and an increased anti-MAP antibodies antibody response [10-12]. Nevertheless, the results of this kind of in vitro test may not be representative of the general population and could be difficult to extrapolate and interpret [5].

The in vivo version of the previously mentioned test allows visualizing IFN-γ production from a measurable skin reaction, caused by the intradermal injection of johnin since the skin thickness is measured before and 72 hours after the inoculation of the purified antigen. Increases >2 mm indicate the occurrence of delayed-type hypersensitivity. However, sensitization to the Mycobacterium avium complex is widespread in livestock and other animals, and neither avian tuberculin nor johnin is highly specific. The specificity of this test is close to 80%, but its sensibility cut-off values had not been established so far [13-15].

Antibody-based tests being the most popular one, the enzymelinked immunosorbent assay (ELISA), relies on the occurrence of an immune response against MAP infection [16]. ELISA is also the most extensively used to establish herd-level PTB status, in other words, for epidemiological studies. Several commercial ELISA kits for PTB diagnosis are currently available, and multiple studies have compared their accuracy and usefulness in different animal hosts and matrices [7,8,17-26]. ELISA has shown limitations, mainly those related to a low sensitivity, which is really related to the progress of the disease, rather than to limitations of the test itself, since the slow progression of MAP infection does not ensure an adequate detection capacity of animals in an early stage [6,16]. Nevertheless, the sensitivity of ELISA is the highest for animals in the clinical stage of the disease or those that excrete a considerable number of bacteria [27,28]. As an extra advantage, ELISA is highly specific with a low presentation of false-positive results [16,25,29], inexpensive, easy to perform, and quantitative results can be obtained in 1-2 hours in everyday practice [16,30].

From a more modern point of view, the detection of MAP genes by polymerase chain reaction (PCR) has shown advantages, including speed, specificity, lack of contamination, and no additional tests are needed to confirm MAP identity. On the other hand, moderate sensitivity, high cost, special equipment, and skilled personnel are required. Despite the latter, due to recent developments in PCR, it is being proposed for herd screening [1,31].

PCR performs as culture confirmatory test, but its direct application to clinical samples has been challenging, mainly due to the problems associated with complex matrices such as milk, feces, and blood, and, of course, the presence of inhibitors [32-34]. It is important to highlight those limits on detection, sensitivity, and specificity vary according to the targeted sequence and primer choice as well as the matrix tested and the PCR format (i.e. conventional gel-based PCR, reverse transcriptase PCR, nested PCR, real-time PCR, multiplex PCR). Molecular setups and methods for MAP enrichment or concentration are flexible, presenting pros and cons reliant on the matrices used and the way to be accomplished [35-36].

Last but not least, culture is still considered the gold standard for MAP detection and PTB diagnosis [5,37,38]. Its sensitivity is around 44% in MAP-infected cattle [5], due to the irregular shedding of bacteria and diverse features of the culture technique per se [39]. This result inevitably affects the sensitivity of the technique (culture) and the matrix (feces), leading to low detection performance, even of symptomatic animals. The specificity is almost 100% [5], even higher if the obtained isolates are confirmed as MAP by molecular methods such as PCR [5,40,41]. Disadvantages of culture include long detection time-mainly when a solid culture media is used, 12 to 16 weeks or longer, recognition of only animals actively eliminating MAP in feces, contamination risk with other mycobacteria or fungi, and the relatively high fees when compared to other tests [42]. The culture of MAP can be done either on liquid or solid media. Liquid culture methods have greater analytical and diagnostics sensitivity than solid medium and growth can be detected sooner, but a formal identification of MAP by genotypic methods is required (i.e. PCR), making the identification of MAP more difficult and expensive [39,43]. On the other hand, the identification of the organism is more difficult in liquid culture because the appearance of colonies and mycobactin dependence are not observable, and the growth of other organisms needs to be distinguished. Moreover, solid culture is more sensitive to recover C strains of MAP, since the ability of solid media to support their growth is well established [43].

Culture of pooled fecal samples as well as environmental sampling, are cost-effective approaches in the classification of herds as MAP-infected [17,44-51].

When a test combination is on the horizon -whatever the formula is, it must be considered that some infected cows have been producing antibodies several years prior to being able to find detectable quantities of MAP in feces. Or another way of saying it is that antibodies may not be detectable during the preliminary stages of infection, when MAP fecal shedding is minimal [16,52,53].

In any case, sampling of all adult cattle in every herd (mainly those over 2 years of age) -increasing the detection spectrum, and of the environment, the consideration of serialized testing, and the use of two or three tests have been suggested for herd screening and to increase the accurateness of MAP diagnosis, being the most reliable strategy when sanitary decisions must be made [1,31,54- 57].

In the future, the improvement of laboratory diagnostic capacities is needed, increasing research foundations in the microbiologic, immunologic, epidemiologic, and economic aspects of the agent and the disease, even in consideration of the specific conditions of each biological or productive region, because “Mama always said life was like a box of chocolates... you never know what you’re gonna get” (Forrest Gump).

When is Surgery an Option for Infectious Bowel Disease? by Francesk M

Abstract

Inflammatory bowel disease is comprised of two major disorders: Crohn’s disease and ulcerative colitis. Crohn’s disease is a chronic inflammatory, idiopathic disorder that affects any part of the gastrointestinal tract from the mouth to the anus, while ulcerative colitis is a chronic inflammatory, idiopathic disorder that affects the large bowel. Despite the new and ever expanding array of medications for the treatment of inflammatory bowel disease, there are still clear indications for operative management.

Key words: Crohn's Disease; Ulcerative Colitis; Surgical Treatment; Inflammatory Bowel Disease; Laparoscopic Surgery

Introduction

Crohn’s disease is a chronic inflammatory, idiopathic disorder that affects any part of the gastrointestinal tract from the mouth to the anus. Individuals with Crohn’s disease often experience periods of symptomatic relapse and remission. The estimated prevalence of Crohn’s disease is about 322 cases per 100,000 persons among adults in Europe and 43 per 100,000 among children.  It is considered a disease of the rich, as the estimated prevalence of Crohn’s disease is higher in urban areas and upper socioeconomic classes. It is thought that this is due to increased access to the health care system [1].

The exact cause of Crohn’s disease remains unknown. Several factors (genetic, environmental, immunologic, dietary etc.) are thought to play a role to the pathogenesis of Crohn’s disease. IBD1 gene located on the chromosome 16 is believed to contribute to the pathogenesis of the disease.  Furthermore, infectious agents such as Mycobacterium paratuberculosis, Pseudomonas species, Listeria species, environmental factors such as tobacco use and dietary factors such as a diet high in fatty acids have all been implicated in the pathogenesis of Crohn’s disease. Crohn’s disease is a chronic inflammatory disease that affects primarily the superficial mucosa and then spreads to the deeper mucosal areas, causing transmural inflammation.  Granuloma formation is pathognomonic of Crohn disease. The granulomas extend through all layers of the intestinal wall and into the mesentery and the regional lymph nodes.

Clinical manifestations of the disease include constitutional symptoms such as low grade fever, weight loss, and fatigue. As mentioned before, Crohn’s disease affects any part of the gastrointestinal tract. Oral manifestations such as oral ulcers are quite common. When the small intestine is affected, diarrhea, malabsorption, weight loss and abdominal pain are the predominant symptoms. When the colon is affected (terminal ileum is the most common affected part of the gastrointestinal tract), the patients report diffuse pain accompanied by diarrhea with blood and mucus in the stool. Extra-intestinal manifestations are also quite common in Crohn’s disease. It also affects skin, joints, eyes, liver and bile duct. Arthritis is the most common extra-intestinal manifestation. Central or axial arthritis, such as sacroiliitis, or ankylosing spondylitis, may also occur. Examination of the skin reveals erythema nodosum and pyoderma gangrenosum. Eye manifestations include uveitis, iritis, and episcleritis. Primary sclerosing cholangitis occurs in approximately 5 percent of patients [2,3].

Complications of the Crohn’s disease include: Fistulae that may develop between the diseased bowel and a variety of adjacent tissues, abdominal abscesses and small bowel obstruction and perianal abnormalities (abscesses and fistulae). It is worth mentioning that in threatening the above mentioning situations, a consultation with a surgeon is often needed [4].

The diagnosis of Crohn’s disease is based on laboratory tests, imaging studies and more invasive procedures, such as endoscopic visualization and biopsy.  Routine laboratory studies that are quite useful in the diagnostic process of Crohn’s disease include: CBC count, chemistry panel, liver function tests and inflammatory markers. It is worth mentioning that fecal calprotectin is a new marker that is proven to be quite useful in the diagnostic process and in the prediction of clinical relapse of inflammatory bowel disease. Specifically, the fecal calprotectin is a calcium- and zinc-binding protein, which for practical purposes can be considered to be neutrophil-specific. Fecal calprotectin test is a functional quantitative measure of intestinal inflammation. Therefore, fecal calprotectin tests are quite useful in gastroenterologists, in order to distinguish inflammatory bowel disease from other common diseases, such as irritable bowel syndrome. Except from the above, calprotectin also predicts imminent clinical relapse with an 80% sensitivity and accuracy in patients with established, relatively asymptomatic inflammatory bowel disease (ulcerative colitis or Crohn’s disease) [5].

Treatment options are individualized based on the severity of symptoms and the complications of the disease. In mild affected patients, such as patients with mild disease limited to the terminal ileum and/or colon and no complications, enteric-coated budesonide as the first line treatment for inducing remission. The use of 5-aminosalicylates (5-ASA) for Crohn’s disease is controversial, and we limit its use to patients with mild Crohn’s disease with limited ileocolonic involvement who prefer to avoid glucocorticoids. For patients with limited ileitis and mild symptoms, a slow release, oral 5-ASA agent is suitable, such as mesalamine (eg, Pentasa or Asacol). By contrast, sulfasalazine (the prodrug of 5-aminosalicylate) is less useful for ileitis because colonic bacteria must cleave the drug to release the active 5-ASA moiety, so it is reserved for cases of colitis. For low-risk patients with mild Crohn’s disease who achieved remission with a glucocorticoid tapering and then discontinuing the glucocorticoid is recommended. For low-risk patients with mild Crohn’s colitis who achieved remission with a 5-ASA agent (or sulfasalazine), the same agent should be used for long-term maintenance therapy [6-8]. On the contrast,  patients with moderate to severe Crohn’s disease ie patients younger than 30 years , with tobacco use with elevated C-reactive protein and/or fecal calprotectin levels, deep ulcers on colonoscopy ,long segments of small and/or large bowel involvement, perianal disease, extra-intestinal manifestations, history of bowel resections, first-line options for induction therapy include a biologic agent tumor necrosis factor-alpha (TNF) inhibitor (eg, infliximab) with or without an immunomodulator (eg, azathioprine [AZA], 6-mercaptopurine [6-MP], or methotrexate).After clinical, endoscopic, and histologic remission following induction with combination therapy, the same agents are used for one to two years [9-12]. For many patients with Crohn’s disease, may have a continuous and progressive course of active disease, while approximately 20 percent of patients experience prolonged remission after initial presentation. There is an increased incidence of squamous cell carcinoma of the anus and skin, adenocarcinoma of the small bowel and duodenal neoplasia in patients with Crohn’s disease [13-15].

Ulcerative colitis is a chronic inflammatory, idiopathic disorder that affects the large bowel. It is three times more common than Crohn disease.In the United States, about 1 million people are affected with ulcerative colitis. The exact cause of ulcerative colitis remains unknown. Several factors (genetic, environmental, immunologic, dietary etc.) are thought to play a role to the pathogenesis of the disease. A family history of ulcerative colitis (observed in 1 in 6 relatives) is associated with a higher risk for developing the disease. Disease concordance has been documented in monozygotic twins. Unlike Crohn’s disease, smoking is negatively associated with ulcerative colitis. Dietary factors such as milk consumption may exacerbate the disease. Last but not least, psychological and psychosocial stress factors can play a role in exacerbations of ulcerative colitis.

Ulcerative colitis is a chronic inflammatory disease that affects colonic mucosa. It involves erosions and/or ulcers and individuals with Crohn’s ulcerative colitis often experience periods of symptomatic relapse and remission. As mentioned above, ulcerative colitis affects predominantly the colon. Clinical manifestations of the disease include rectal bleeding and diarrhea with mucus in the stool. Lower abdominal pain is also a common symptom. Extra-intestinal manifestations are also quite common in ulcerative colitis. These include uveitis, pyoderma gangrenosum, pleuritis, erythema nodosum, ankylosing spondylitis, and spondyloarthropathies. Among them arthropathies are the most common, with an incidence of 39% and primary sclerosing cholangitisis is a potentially serious condition, which can often lead to liver failure. Complications of ulcerative colitis include: Severe bleeding happens in up to 10 percent of patients. Massive hemorrhage occurs in up to 3 percent of patients [16,17]. Urgent colectomy may be needed in these cases [18]. Another complication is fulminant colitis with more than 10 stools per day, bleeding, abdominal pain,and distension. Patients with fulminant colitis are at high risk of developing toxic megacolon. Perforation of the colon most commonly occurs as a consequence of toxic megacolon and requires surgical intervention [16].

Treatment options in ulcerative colitis are individualized based on the severity of symptoms of the disease. Patients with mild clinical disease are considered those who have ≤4 stools per day with or without small amounts of blood, no signs of systemic toxicity and a normal C-reactive protein (CRP) and/or erythrocyte sedimentation rate (ESR). Patients with moderate clinical disease may have frequent (four to six per day) loose, bloody stools, mild anemia, and abdominal pain that is not severe. Patients have no or minimal signs of systemic toxicity.  Patients with a severe clinical disease typically have frequent loose bloody stools (≥6 per day) with severe cramps and evidence of systemic toxicity as demonstrated by a fever (temperature ≥37.8°C), tachycardia (heart rate ≥90 beats per minute), anemia (hemoglobin <10.0 g/dL), and/or an elevated CRP or ESR. For patients with mild disease, mesalazine is the drug of choice in inducing remission and preventing relapse [19-23]. For patients with severe disease, the use of glucocorticosteroids is necessery in inducing remission. For patients with steroid-resistant disease, monoclonal antibodies such as infliximab, adalimumab, and golimumab are used [24,25].

Generally, anal and colon lesions can occur due to infectious and neoplastic etiology, and a prompt and multidisciplinary approach may prevent poor outcomes [26]. Patients with ulcerative colitis are at increased risk for colorectal cancer. The risk appears to be highest in patients with pancolitis and begins to increase 8 to 10 years following the onset of symptoms in patients with pancolitis. In one prospective study, the incidence of colorectal cancer was 2.5 percent after 20 years and 7.6 percent after 30 years of disease [27].

Surgery as an Option

Indications for operation in Crohn’s disease are failure of medical management (most common reason), extra-intestinal manifestations (25%), intestinal obstruction, fistulas with associated abscess or stricture, perforation, bleeding and cancer. Resection is the most commonly performed surgical procedure for small bowel Crohn's disease. Other surgical options for the treatment of small bowel Crohn's disease include bypass operations or ileostomy formation. These procedures can also be performed laparoscopically with decreased morbidity and length of stay in the hospital [28,29]. Laparoscopic minimally invasive surgery should be preferred to open surgery due to its advantages [30].

Indications for operation in ulcerative colitis are failure of medical management (most common reason), risk of malignancy and severe extra-intestinal manifestations of ulcerative colitis. Worsening signs and symptoms of colitis, including numerous bloody stools per day, fever, elevated heart rate, anemia, elevated sedimentation rate, radiographic evidence of colonic distension, and abdominal distension with tenderness on exam are indications for an emergent surgery. Total proctocolectomy with end ileostomy remains the operative standard against which all other resections for ulcerative colitis are compared. Surgical options of ulcerative colitis in the emergent setting is aimed toward removing the inflamed bowel while minimizing morbidity, and a total abdominal colectomy and end ileostomy is the procedure of choice [28,29]

January series: clap 7

I'm truly sorry to complain all the time... maybe I should change my blog description: "I'm complaining all the time, welcome to my blog".

But I'm just so cold. I don't know if I'm weak or if the disease is strong but I just feel awful and I'm so cold...

Worked on, flash carded and kinda learn three chapters on bovine digestiv disease including the very interesting one on paratuberculosis

Nothing else as I fell back to sleep just after finishing my breakfeast this morning until 12.

At least the little planty on my desk is happy... I really like to see its little greeny fingers...

Crohn’s Disease: A Curable Disease Held Hostage?

Authored by Gilles RG Monif*

Introduction

Permanent remissions have been attained in Crohn’s disease. Nevertheless, the current focus of therapy remains sclerosed with the prevailing drug therapy through which temporary remissions are attainable. FDA’s reliance on evidence-based validation through comparative, placebo controlled, double-blinded studies has created an impediment to acceptance of divergent alternated therapies as being within the standard of care. In so doing, FDA has basically surrendered the therapeutic dialogue of Crohn’s disease to those who can pay for such studies.

Keywords: Crohn’s disease; Hruska Postulate; Permanent remission

Introduction

The current standard of care of Crohn’s disease evolved from trial-and-error therapeutic attempts to address the signs and symptoms of disease. The prevailing standard of care is based on “evidence-based” data, demonstrating that the current drugs of choice produce a statistically significant improvement of disease over placebo or alternative therapy. For over two decades, disruption of the effector arm of the immune response has been the foundation of Crohn’s disease therapy. Despite not having produced cures in over a decade of clinical use, biologics have attained the status of drugs-of-choice for Crohn’s disease. The rush to disease plication has overshadowed the clinical observations that two divergent therapeutic approaches (diet and anti-tuberculosis drugs) have produced occasional permanent remissions. These isolated instances of permanent remission induction have been glossed over by their failure to constitute being “evidence-based” data. For the Food and Drug Administration (FDA) and other government agencies to accept a clinical therapeutic outcome, the data needs to be “evidence-based” derived from primarily comparative, doubleblinded, placebo-controlled studies.

In 2015, a pathogenesis for Crohn’s disease was introduced that put into focus the shared mechanism by which dietary manipulation and selected anti-mycobacterial therapy had achieved long-term remissions/cures [1]. The Hruska Postulate proposed the thesis that, in the absence of functional acquired immunity, a newborn infected by Mycobacterium avium subspecies paratuberculosis (MAP) could be so challenged to abort mycobacterium replication that its inherent immune system became fixed within immunological memory. Owing to the loss of immunological tolerance, every time the baby’s immune system encountered MAP. it would again respond by elaborating pro-inflammatory cytokines directed at MAP at its points of mucosal attachment to the gastrointestinal mucosa and its antigen processing. A major factor complicating attempts to construct meaningful comparative therapeutic groups for clinical trials is the degree to which the gastrointestinal microbiota has altered gastrointestinal structure and function [2-4]. Once mucosal integrity is lost, the microbiota of the gastrointestinal tract becomes a superimposed disease process. The failure to address the resultant polymicrobial infection is responsible for the permanent sequel of Crohn’s disease: strictures, bowel-to-bowel fistulae, perianal fistula bowel perforation, sepsis, etc. Once in place, the resultant alterations of structure and function create therapeutic subgroups which necessitated added therapy. Given biologics and steroids failure to attain but temporary remissions, the under-addressed question is how do diet or selected anti-microbial drugs induce isolate cures?

That diet could be a therapeutic modality has long been inferred. Before the introduction of biologics, diet had long been used in front line therapy for Crohn’s disease in Japan. In the United States. selected pediatric gastroenterologists using dietary manipulations have documented a beneficial effect, but not cures [5-7]. In isolated instances, individuals afflicted with Crohn’s disease have achieved permanent remission by rigid adherence to what are variations of basically vegetarian-like regimens. Chiba, et al. reported that 94% of Crohn’s afflicted individuals who remained on a semi-vegetarian diet maintained their clinical remission whereas 33% who returned to a regular diet relapsed [8] Much of this clinical response has bene attributed to reducing the volume of antigen challenges by exclusion of foods potentially adulterated by MAP [2]. The question left unanswered had been why. A veterinary experiment-in-nature demonstrated that dietary targeting to enhance host immunity produced the mass destruction of MAP with terminal Johne’s disease (due to the replication of MAP) [9]. In Crohn’s disease, the diarrhea and loss of absorption areas cause significant loss of key vitamins and minerals vital to the integrity of host immunity [10]. The cures achieved through dietary manipulation, reduction of antigen challenges, anabolic diet enhancement and enhancement of host immunity speak to a potential mechanism by which individuals have achieved self-cure without pharmaceutical intervention [11].

The explanation as to why selected anti-mycobacterial drugs have achieved permanent remissions is less obvious [12-14]. Unlike Johne’s disease in domestic animals, Crohn’s disease is not due to organism replication. MAP can’t be identified with special stains nor isolated from disease tissue. Prior attempts to cure Crohn’s disease using anti-tuberculosis drugs largely failed. Why selected anti-MAP therapy has produced individual cures is due to their ability, not to destroy MAP as such, but to destroy MAP that exists in its cell-wall free state. The MAPs that drive the dysfunctional immune response exist as cell wall free versions of itself. The prior failures of prior anti-tuberculosis drugs are largely attributable to their mechanism of action being directed against mycobacterium cell wall. The expanded Hruska Postulate states abortion of the immune-mediated aspect of Crohn’s disease is contingent on the destruction of the sustaining MAP immune template. To destroy MAP in its cell wall-free form, drug therapy must be able to disrupt MAP’s RNA metabolism.

Given the number of years required to assess outcome, the subset of patient groups based upon degree of documented tissue damage required, age, immune status, diet, etc., make conducting a comparative, placebo-controlled, double blinded comparative study against a given biologic a near impossibility that no one will pay for. Unless FDA begins to accept small clinical trials, whose endpoint is either failure or success without continued drug therapy over a prolonged period of time to be “evidence-based”, the therapy of Crohn’s disease will continue to reside with those that can pay the bill for the creation of “evidenced-based” data. Without FDA validation, physicians attempting innovative therapies face loss of liability protection afforded by the “standard of care”. Currently, the will to cure Crohn’s disease appears subordinate to FDA’s inflexibility and the elephant in the room. Chronic diseases function as a revenue enhancer for both healthcare provider and the pharmaceutical industry. In 2018, the maker of the principal biologic used in the therapy of Crohn’s disease made a reputed 19.94 billion dollars. The 2018 American College of Gastroenterology’s Clinical Guideline states “Despite the recent advances in the treatment of patients with CD, there still remains a large group of patients who do not respond adequately to our current medication armamentarium.” ……. We will certainly expand our medical treatment war chest and uncover effective biologics with different mechanisms of action to treat our patient. If the initial biologic drug fails, the patient will be able to be switch to another agent and even combination biologics may become a reality [15]. The Guideline further states that the standard of care is “rigid’ and “rarely violated”.
