Although there is information on adult endoscopy units, E digestive disorders in childhood. Pediatric endoscopy has little guidance is available to the pediatric endoscopy practitioner. The location where these procedures are Procedures Committee, is to review the important considerations for setting performed has shifted over time. Gradually more ment, needed equipment, motility setup, billing and coding, and pediatric institutions and facilities have begun using more specialized ambu speci? This report is meant to provide practical guidance by summarizing available expert opinions on the topic of setting up a pediatric endoscopy Received August 16, 2015; accepted March 2, 2016. It is important to keep this point in mind if adapting citations appear in the printed text, and links to the digital? Ideally, the reprocessing area is most efficient when it greater volume and complexity of services commonly strained this can be located directly adjacent to and shared with the other original arrangement. Care should be taken to allow for efficient storage and access of equipment and supplies. Nurses should have accessories, supplies, and medications available in cabinets directly behind them. This type of set up may be staffed by generic personnel and design to keep lines, cords and equipment off the floor and may often results in decreased efficiency as elective procedures are often be helpful depending on the room. Shared pediatric and adult Although the most common facility used by adult popu endoscopy units and freestanding surgery centers are also fre lations is the freestanding ambulatory endoscopy center, the quently employed. A consideration of these set-ups is the potential pediatric unit will likely have less demand for endoscopy than for lack of pediatric-specific design and medical personnel specifi an adult population. Therefore, the pediatric unit may serve a dual cally trained in the care of children and adolescents, although the purpose of inpatient and outpatient procedures, as opposed to a advantages include proximity to adult expertise and equipment. It should have easy access for pediatric-specific model in which dedicated pediatric gastroenter outpatient populations, and be accessible to inpatients as well. When designing the unit, thought should be made to the Design of the Unit sharing of facilities and resources with other departments. To prevent future problems, the architect and licensing agencies should this section is an adjunct to architectural planning and is a be consulted regarding all possible uses of the unit, as regulations supplement to healthcare and building coding guidelines such as may vary based on the intended use. For example, if the Pulmonary those laid out by the State Department of Health Services, State Fire service at the hospital will be sharing the space to perform broncho Marshal, Joint Commission for Ambulatory Health Organizations, scopy, the state guidelines for airflow must be reviewed and Medicaid and Medicare services, and so on. Thorough discussion accommodated to be certain negative airflow is provided (refer should take place with the hospital system facility management or a to jurisdictional guidelines). The Anesthesia service will also need state licensed architect familiar with healthcare facilities. The proper scavenger systems, wall oxygen, and suction to support all coding of these facilities will vary from state to state. Attention to these areas may prevent the also variability within North America, that is, Canada. Space Planning Reception and Waiting Rooms Anticipated procedure volumes provide useful space esti Easing anxiety on the day of the procedure begins with a mates based on planned procedure room utilization rates and ratios well-designed entry. The waiting area should be child friendly with of procedure rooms to waiting spaces and recovery beds (3). Space adequate seating for the patient, parents, and other accompanying projections should include the likelihood for growth in volume and children. Making the waiting room as home-like as possible has potential of expansion of provided services over time. Consider been shown to reduce anxiety for both the parents and the patient ations of space are among the most difficult and carry the greatest (5). The comfort level and the efficiency of the unit may be Procedure Room improved with dual-use preparation and recovery rooms. The preparation and recovery rooms should be in direct view of the the procedure room needs to be large enough to allow for the nursing station. Advantages of separate room should be at least 400 sq ft with more space often needed areas include simplicity and specificity of design, patient confi for advanced cases. The Two separate entrance/exit doors should provide access to model may also be dependent on whether anesthesia or conscious the procedure room: 1 to allow for the entry of the patient and clean sedation is used, as recovery times are different. The true incidence fluoroscopy rooms be leaded, although the requirements for this of infections is, however, unknown because of inadequate surveil vary within states and provinces (12). The Centers for endoscopists can complete procedure notes, enter patient orders, Disease Control has also issued an interim duodenoscope surveil and coordinate care by phone. Providing these capabilities requires well-trained special related to scope reprocessing. Althoughtheseguidelinesarehelpful, there isa lackof reprocessing issues for various endoscope attachments and men universally acceptable qualifications for training endoscopy staff. Staff changing rooms are not usually required by state Before making a decision about the number of staff needed it licensing and national authorities. This infor weighted scale per procedure such that an esophagogastroduodeno mation can be found at. If advanced procedures are personnel should demonstrate competence in the duties they are expected such as dilation, injection, or polypectomy, an extra 15 to assigned to . Many outpatient procedures are done in morning which the pediatric endoscopy unit functions as a part of an adult blocks so as to limit fasting time in young children, and this is endoscopy suite, the nursing staff need to have the specific skill set also a consideration when projecting volumes. Ability to communicate In a setting where learners are performing the procedure, a with parents, secure intravenous access in small children, and possibility of increased procedural time should be considered knowledge of applicable pediatric endoscopic and resuscitation depending on the center. This can be obtained through conferences, residents and medical students are participating in sedation. Even if the state does not require ongoing educational activities it would be prudent Optimizing Ef? Room efficiency is determined by intrinsic factors such as Endoscopy managers can be nurses or human resources patient delays, scheduling conflicts, and equipment maintenance. Ensuring job satisfaction variables regarding personnel, equipment, flow, and culture, it is can create an effective team and minimize turnover. Determining the number of staff needed to run the endoscopy When conducting a time study, it helps to break up the day unit is dependent on many factors. Many centers do not have enough volume of has been described anywhere between 10 and 30 minutes and pediatric endoscopy cases to function independently. Several equations have been developed to estimate the Having baseline data analysis will allow for identification of minimum number of personnel needed to run a unit (14). Patient no-show at time of practice can complete up to 3000 endoscopies in each room. It is helpful to develop a perform any procedure in his or her allocated block time even if the 298 This means For hospitals that have both inpatient and outpatient pro procedures are done with nurses who are likely not trained for cedures in the endoscopy unit, there are additional challenges such endoscopic procedures. Thus, cost, efficiency, and volumes must as coordination of patient transport, unstable patients, and emer be considered when designing the after-hours strategy for an gency cases. This system significantly improved Documentation timely discharge of inpatients, limited delays in scheduled cases, and decreased overtime pay (20). A standard approach to documentation should have the Interventions targeted toward improving efficiency are sum following objectives: marized in Table 2 and based on establishing an ongoing assessment of the endoscopy unit. Establishing a rationale for any deviations from the standard of surveys should be used as an indicator of quality of service. A recent study on patient experience in There are 3 broad areas of documentation in a pediatric pediatric endoscopy identified important aspects from the patient endoscopy unit: nursing documentation before and after procedure, and family perspective (21). The Joint Commission on Accreditation of Emergency and Weekend Coverage Healthcare Organizations provides guidance on components of documentation (25). Table 3 provides a brief comparison of the Plans for staffing should be determined for weekend and different products available. The availability of an on-call and weekend when comparing products is the capability of importing the pro endoscopy nurse is associated with earlier upper endoscopy for cedural record into the hospital electronic health record. Some units schedule a late shift that Nursing Record routinely covers after-hours and overnight emergencies. This relieves the at presentation, and identify any specific issues to address before endoscopist of the responsibility to transport the endoscopy cart, beginning the procedure. On-call staff should should include verification/placement of intravenous line, all per be qualified to function independently in those areas.

Complications (if any) channel size varies on the slim gastroscopes (Table 4) (29). This in combination with fewer devices that fit into the smaller channel limits the therapeutic options available in a smaller patient (30). Sedation Record Colonoscope If another provider administers sedation, or general anesthe sia is used, a separate record should be completed by that provider. It should be noted that the endoscope, light source, and video colonoscopes have an auxiliary channel! Many of distal 20 to 40 cm of colon/rectum as in a flexible sigmoidoscopy, the new processors have narrow band imaging that is used in the an appropriate sized gastroscope may be used with the correspond detection of dysplastic lesions in adults, although pediatric use has ing forceps as an alternative to a colonoscope or sigmoidoscope. The cost of each unit is highly dependent on the digital interface and resolution of each processor. Tissue and Sample Acquisition Image Management Biopsy forceps include design options such as disposable versus reusable forceps and cup with or without needle spike. The images (single still image and/or video clip) captured Disposable forceps may be more reliable and cost effective, but from the endoscope are transmitted to a hard drive for management operator preference is a consideration. The image management software may be purchased useful for raised vascular lesions or gastric polyps to allow for separately or combined with the video processor depending on the hemostasis. A polyp trap may also be used to obtain duodenal format, video format and editing, and procedure documentation. Therapeutic Endoscopy Light Source and Video Processor Treatment of nonvariceal bleeding by means of endoscopy includes injection, tamponade via clip placement, and cautery.

Patients should be made aware of signs and symptoms of blood loss and instructed to report them immediately or go to an emergency room. There is no established way to reverse the anticoagulant effect of apixaban, which can be expected to persist for about 24 hours after the last dose, i. Because of high plasma protein binding, apixaban is not expected to be dialyzable [see Clinical Pharmacology (12. Protamine sulfate and vitamin K would not be expected to affect the anticoagulant activity of apixaban. There is no experience with antifibrinolytic agents (tranexamic acid, aminocaproic acid) in individuals receiving apixaban. There is neither scientific rationale for reversal nor experience with systemic hemostatics (desmopressin and aprotinin) in individuals receiving apixaban. Activated oral charcoal reduces absorption of apixaban, thereby lowering apixaban plasma concentration [see Overdosage (10)]. Major bleeding was defined as clinically overt bleeding that was accompanied by one or more of the following: a decrease in hemoglobin of 2 g/dL or more; a transfusion of 2 or more units of packed red blood cells; bleeding that occurred in at least one of the following critical sites: intracranial, intraspinal, intraocular, pericardial, intra-articular, intramuscular with compartment syndrome, retroperitoneal; or bleeding that was fatal. Intracranial hemorrhage included intracerebral (hemorrhagic stroke), subarachnoid, and subdural bleeds. Events associated with each endpoint were counted once per subject, but subjects may have contributed events to multiple endpoints. Treatment is likely to increase the risk of hemorrhage during pregnancy and delivery. Treatment of pregnant rats, rabbits, and mice after implantation until the end of gestation resulted in fetal exposure to apixaban, but was not associated with increased risk for fetal malformations or toxicity. Treatment of pregnant rats from implantation (gestation Day 7) to weaning (lactation Day 21) with apixaban at a dose of 1000 mg/kg (about 5 times the human exposure based on unbound apixaban) did not result in death of offspring or death of mother rats during labor in association with uterine bleeding. However, increased incidence of maternal bleeding, primarily during gestation, occurred at apixaban doses of? In controlled clinical trials, orally administered apixaban in healthy subjects at doses up to 50 mg daily for 3 to 7 days (25 mg twice-daily for 7 days or 50 mg once-daily for 3 days) had no clinically relevant adverse effects. Thus, administration of activated charcoal may be useful in the management of apixaban overdose or accidental ingestion by leading to a more rapid fall in apixaban blood levels. Its molecular formula is C25H25N5O4, which corresponds to a molecular weight of 459. The film coating contains lactose monohydrate, hypromellose, titanium dioxide, triacetin, and yellow iron oxide (2. Apixaban has no direct effect on platelet aggregation, but indirectly inhibits platelet aggregation induced by thrombin. Changes observed in these clotting tests at the expected therapeutic dose, however, are small, subject to a high degree of variability, and not useful in monitoring the anticoagulation effect of apixaban. Pharmacodynamic Drug Interaction Studies Pharmacodynamic drug interaction studies with aspirin, clopidogrel, aspirin and clopidogrel, enoxaparin, and naproxen were conducted. However, in patients with moderate hepatic impairment, there is no clear understanding of the impact of this degree of hepatic function impairment on the coagulation cascade and its relationship to efficacy and bleeding. Thus, despite a short clearance half-life of about 6 hours, the apparent half-life during repeat dosing is about 12 hours, which allows twice-daily dosing to provide effective anticoagulation, but it also means that when the drug is stopped for surgery, anticoagulation persists for at least a day. Apixaban is absorbed throughout the gastrointestinal tract with the distal small bowel and ascending colon contributing about 55% of apixaban absorption. Apixaban demonstrates linear pharmacokinetics with dose proportional increases in exposure for oral doses up to 10 mg. O-demethylation and hydroxylation at the 3-oxopiperidinyl moiety are the major sites of biotransformation. Unchanged apixaban is the major drug-related component in human plasma; there are no active circulating metabolites. Biliary and direct intestinal excretion contributes to elimination of apixaban in the feces. Following intravenous administration, apixaban is eliminated with a dominant half-life of ~ 5 hours. Following oral administration, the apparent half-life is ~12 hours because of prolonged absorption. Apixaban is a substrate of transport proteins: P-gp and breast cancer resistance protein. Therefore, apixaban is not expected to alter the metabolic clearance of coadministered drugs that are metabolized by these enzymes. The effects of coadministered drugs on the pharmacokinetics of apixaban and associated dose recommendations are summarized in Figure 2 [see also Warnings and Precautions (5. Dosing recommendations were also informed by clinical considerations [see Warnings and Precautions (5. In dedicated studies conducted in healthy subjects, famotidine, atenolol, and enoxaparin did not meaningfully alter the pharmacokinetics of apixaban. In studies conducted in healthy subjects, apixaban did not meaningfully alter the pharmacokinetics of digoxin, naproxen, atenolol, or acetylsalicylic acid. Specific Populations the effects of level of renal impairment, age, body weight, level of hepatic impairment, gender, and ethnic origin on the pharmacokinetics of apixaban are summarized in Figure 3. A study in healthy subjects comparing the pharmacokinetics in males and females showed no meaningful difference. The results across pharmacokinetic studies in normal subjects showed no differences in apixaban pharmacokinetics among White/Caucasian, Asian, and Black/African American subjects. Systemic exposures of unbound apixaban in male and female rats at the highest dose tested (600 mg/kg/day) were 2 and 4 times, respectively, the human exposure. Mutagenesis: Apixaban was neither mutagenic in the bacterial reverse mutation (Ames) assay, nor clastogenic in Chinese hamster ovary cells in vitro, in a 1-month in vivo/in vitro cytogenetics study in rat peripheral blood lymphocytes, or in a rat micronucleus study in vivo. Impairment of Fertility: Apixaban had no effect on fertility in male or female rats when given at doses up to 600 mg/kg/day, a dose resulting in exposure levels that are 3 and 4 times, respectively, the human exposure. Apixaban administered to female rats at doses up to 1000 mg/kg/day from implantation through the end of lactation produced no adverse findings in male offspring (F1 generation) at doses up to 1000 mg/kg/day, a dose resulting in exposure that is 5 times the human exposure. Adverse effects in the F1-generation female offspring were limited to decreased mating and fertility indices at 1000 mg/kg/day. A total of 18,201 patients were randomized and followed on study treatment for a median of 89 weeks. Concomitant diseases of patients in this study included hypertension 88%, diabetes 25%, congestive heart failure (or left ventricular ejection fraction? Superiority to warfarin was primarily attributable to a reduction in hemorrhagic stroke and ischemic strokes with hemorrhagic conversion compared to warfarin. Advise patients about how to recognize bleeding or symptoms of hypovolemia and of the urgent need to report any unusual bleeding to their physician. Ask your doctor or pharmacist if you are not sure if your medicine is one listed above. Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Keep a list of them to show your doctor and pharmacist when you get a new medicine. Call your doctor or get medical help right away if you have any of the following symptoms:? Inactive ingredients: anhydrous lactose, microcrystalline cellulose, croscarmellose sodium, sodium lauryl sulfate, and magnesium stearate. The film coating contains lactose monohydrate, hypromellose, titanium dioxide, triacetin, and yellow iron oxide (2. Interactions involving warfarin can be divided into two main groups: Read any standard clinical G pharmacokinetic pharmacy textbook for more G pharmacodynamic. These types of interactions are mainly due to an effect on the metabolism of warfarin, but some drugs also affect the absorption of warfarin, while others can cause displacement from protein binding sites. Pharmacodynamic effects A pharmacodynamic effect is one that increases the risk of bleeding without altering the plasma concentration of warfarin (eg, when paroxetine is taken with warfarin). These interactions may lead to a loss of anticoagulation (thereby increasing the risk of thrombosis) or they may cause over-anticoagulation (thereby leading to a risk of haemorrhage). It is important to understand the mechanism of any drug/drug interaction with warfarin and to know what advice to give to the patient about their warfarin when other medication is altered in any way. Both amiodarone and fluconazole affect this enzyme system and can potentiate the anticoagulant effect of warfarin. Table 3 describes some drugs which are known to interact with warfarin, as 3 described in the British national formulary. Testosterone Refer to current published Tetracyclines Thyroxine references and text for more Tramadol detailed information. Erythromycin and other macrolides interact with warfarin unpredictably and only affect certain individuals. Make a note of the clinically significant drug interactions with warfarin that you come across most often in your practice. Herbal and other alternative medicines Over the last 10 years the use of alternative medicines has increased substantially and therefore it is important to educate patients on the safety of these medicines while taking warfarin. Some alternative medicines, including food supplements, may interact with warfarin. Many alternative health products have no regulations on the strength and quantities of active ingredients and therefore monitoring the addition of an alternative medicine to a patient stabilised on warfarin can be difficult. Hypothyroidism this medical condition results in a reduced metabolic rate, which means vitamin K dependent clotting factors remain in the circulation longer. Thus, a patient with an underactive thyroid will require a higher dose of warfarin. However, when the patient takes levothyroxine and the thyroid function starts to normalise, the warfarin requirement will fall. Hyperthyroidism and fever Both hyperthyroidism and fever result in a hypermetabolic state, which may accelerate the clearance of vitamin K-dependent clotting factors.

External irritation can be due to blepharitis (see blepharitis), contact dermatitis, or 2 hordeola (See hordeolum). Papillary Conjunctivitis this is associated with an allergic immune response, eg vernal keratoconjunctivitis, or a 1 response to a foreign body such as a contact lens or ocular prosthesis. It is more commonly associated with soft lenses than gas permeable lenses, and can be due to thick or poorly 3 designed or manufactured lens edges. The patient will complain of itching, irritation and mucus discharge, and if he is a contact lens wearer, he may experience reduced comfort and excess lens movement, along with visual blur. Papillary conjunctivitis is almost always bilateral, and tends to affect only the upper tarsal conjunctiva, which exhibits papillae and hyperaemia. Stringy mucus may be found in the tear film, and decreasing comfort may cause the patient to eventually cease 3 lens wear. Treatment If the condition is caused by a foreign body response due to a contact lens or ocular prosthesis, then the patient should be refitted with a lens of improved design / fit / material, and the compliance with cleaning the lens or prosthesis should be carefully checked. A more frequent replacement regime may be the answer, and possibly the use of 3 anti-histamines or mast cell stabilisers may be necessary. Follicular Conjunctivitis this may be caused by a variety of conditions, including inflammation due to pathogens 4 such as viruses, atypical bacteria and toxins, including topical medication. Many symptoms are shared with other forms of conjunctivitis, and in this instance follicles will be found on the tarsal conjunctiva. Papillae vs Follicles Papillae are raised areas of inflammation with a central blood vessel, appearing red at the surface and paler at the base. Follicles are an accumulation of white blood cells without a 3 central vessel, and appear pale at the surface and redder at the base. They are transmitted by arthropod vectors including fleas, ticks, biting flies, and lice from animal-to animal (intraspecies) and species to species (interspecies). Direct animal-to-animal transmission, without vectors, probably occurs rarely and is exemplified by the transmission from cats to humans via scratches, bites, and fur contact. Most animal species have their own unique Bartonella species that establish chronic, possibly life-long, infections and carrier states. Cats are infected with at least 6 Bartonella species and most remain healthy carriers for years, or possibly, for their entire lives. The mechanisms involved in the pathogenesis of Bartonella diseases are being elucidated rapidly. Bartonella have a strong tendency to stick or clump together in tissues and in culture and to stick to , and penetrate, erythrocytes and endothelial cells. The ability to adhere to each other, and to the membranes of erythrocytes and endothelial cells, leads to the wide and varied tissue pathogenesis observed in cats, dogs and people. Pili 1 and a protein called deformin are probably responsible for the sticky properties. The broad tissue specificity of Bartonella is due to the adhesion to endothelial cells which are the constituents of capillaries. Bartonella proteins stimulate endothelial cells to proliferate causing neovascularization or angiogenesis and an outpouring of inflammatory cytokines which recruit inflammatory cells such as lymphocytes, plasma cells and macrophages. With the understanding of the pathogenic mechanisms of Bartonella, it is easier to understand the widespread disease distribution of Bartonella-inflammatory diseases in cats: oral diseases, respiratory diseases, ocular diseases, gastrointestinal diseases, skin diseases and diseases in major organs such as the spleen and liver. Infected healthy and diseased cats can be successfully treated with azithromycin, rifampin or doxycycline. Infected cats can transmit their Bartonella to people via scratches (cat scratch disease), bites, or rarely, through simple contact with their fur. It is very important for veterinarians to fully understand the biology of Bartonella in cats and dogs so they can become active in the public health effort to prevent the spread of these potentially dangerous microorganisms to people. I thank the numerous practicing veterinarians for their assistance in gathering the clinical data and therapy evaluations. The clinical Bartonella-disease association could not have been obtained without their collaboration. The genus Rochalimaea has been reclassified as the genus Bartonella and 26 removed from the family Rickettsiaceae of the order Rickettsiales and placed in the family Bartonellaceae. During this time a number of emerging Bartonella diseases have been described in humans, cats and dogs. There are presently more than 16 named species and numerous unnamed species included in this obscure genus: Bartonella bacilliformis, Bartonella henselae, Bartonella clarridgeiae, Bartonella koehlerae, Bartonella weissii, Bartonella quintana, Bartonella doshiae, Bartonella taylorii, Bartonella tribocorum, Bartonella vinsonii, Bartonella elizabethae, Bartonella grahamii, Bartonella woshoensis, Bartonella alsatica, Bartonella schoenbuchii and Bartonella capreoli. From the veterinary perspective, the most important members are Bartonella henselae, clarridgeiae, koehlerae, weissii, elizabethae and vinsonii, all of which can cause severe illnesses in cats and dogs and, all of which are zoonotic infections where 17,21-24,28,32,33,40,48,56a,60,62,64,71,73-75,83,84,100-102,111 cats and dogs act as natural reservoirs of the zoonotic pathogenic bacteria. Bartonella elizabethae has recently been identified as a new member of the group and was isolated from a person with endocarditis and has been found to be 36 common in cats in Sweden. Bartonella vinsonii, which was originally isolated from a vole on an island in the St. Lawrence River and 21-23,132 recently from pet dogs with endocarditis, has also been shown to cause a febrile culture-negative endocarditis in humans. Recent studies have shown that pet cats serve as a major persistent reservoir for five Bartonella species: Bartonella henselae, Bartonella clarridgeiae and Bartonella koehlerae, Bartonella weissii, and Bartonella elizabethae, with prolonged, asymptomatic 32,33,35,36,40,53,57,71,75,111,136,141 bacteremia from which humans may become infected. The cat flea, Ctenocephalis felis and deer and dog ticks can carry the bacterium and probably act as vectors transmitting it from cats to humans. Surprisingly, in one study 41% of the healthy cats 75 tested were persistently bacteremic but showed no clinical signs. Identification of infected cats and antibiotic treatment along with control of flea infestations are recommended for decreasing human exposure to Bartonella species. The bacteria are difficult to culture from tissues, are fastidious, but are somewhat easier to culture from blood. In vitro growth is enhanced when nutrient agar medium contains rabbit or sheep blood and the culture is incubated for at least 2 weeks. Isolation of organisms from blood often requires 4 to 6 weeks of incubation before colonies are apparent. Because Bartonella are erythrocyte-associated (internal or on their surfaces) blood culture systems that lyse erythrocytes 79,137 facilitate and enhance isolation of the bacteria from blood. The direct isolation of the bacteria from tissues or blood is difficult due to the fastidious nature of the bacteria. Indirect serological techniques are practical, economical and often superior to direct methods in that 57 the antibody produced in response to infection is an amplification system. Detection of antibody against Bartonella can determine current active infections or, at times, may signify past infections. One ml of sterile blood is added to the lysis tube and the tube is gently inverted several times to lyse the red blood cells. In vitro growth is enhanced when nutrient agar medium contains rabbit or sheep blood and the culture is incubated for several weeks. Isolation of organisms from blood often requires 4 to 6 weeks of incubation before colonies are apparent. Although this method is considered the Gold Standard, the method is insensitive and often (50%) the bacteria cannot be isolated from known infected cats. Table 1 below summarizes the comparison of culture isolation and western immunoblot results from 256 cats. Department of Companion Animal and Special Species Medicine, College of Veterinary Medicine, North Carolina State University, Raleigh, North Carolina Serologic Tests: Compared to culture isolation of Bartonella, which requires special laboratories and 4 to 6 weeks of incubation, serologic tests have the advantage of ease of use, take only 1-2 days, and are economical. Infected cats produce specific antibodies against the bacterial proteins and the antibodies are an amplification system indicating the presence of the bacteria. The presence of antibodies indicates, in most instances, current active Bartonella infection and not a past history of infection. We have developed a specific and sensitive western immunoblot test for detection of antibodies against all species of Bartonella that infect cats and dogs (Figures 2 & 3 and Table 2). We have defined 9 immunodominant proteins of feline Bartonella and have developed a grading system for correlation of western immunoblot reactivity with Bartonella infection (Table 2). There is a high degree of serologic cross-reactivity between all the Bartonella, and the FeBart immunoblot test will detect all feline Bartonella infections in cats. Western immunoblot test results of +3 and +4 are considered positive (Figure 2, 3 & 4) and these cats are considered to be actively infected with Bartonella and should be treated. Following antibiotic therapy we recommend the Western blot antibody titration test, 6 months after the completion of therapy to determine if there is a decrease in 61 antibody titer indicating successful elimination of Bartonella. It is necessary to wait 6 months from the end of therapy in order to allow the antibody level to drop (catabolism) after removal of the Bartonella antigenic stimulation. A 2 to 4 fold decrease in antibody titer indicates successful Bartonella therapy, however, another course of antibiotic therapy is recommended if the antibody titer does not decrease. Occasionally Bartonella can be isolated from cats who do not produce antibody and are seronegative by all tests 107 (Table 1). It is not known if infected cats can clear their Bartonella infections or if they remain infected for life. Cat fleas and ticks spread the bacteria among cats and probably can occasionally transmit the bacteria to people. The prevalence of Bartonella infection varies in different regions of the United States and parallels increasing climatic warmth and annual precipitation (Figure 5 & Table 32,33,60,68,71 3). Warm, humid areas have the highest Bartonella prevalence since they have the highest number of potential arthropod 43,45,47,111,127 vectors such as fleas and ticks. The Southeastern states, Hawaii, costal California, the Pacific Northwest, and the south central plains have the highest incidence whereas the Rocky Mountain and Great Plains states have the lowest prevalence (Figure 6). The prevalence in cats living in Europe and Australia is similar to cats 16,17,19 living in this country. The reason for the higher infection prevalence is due to an increased infestation with fleas compared to cats living in single cat households. The prevalence of infection is 3 times higher for cats with these risk factors than for cats with no known risk factors who live in single-cat households. Infection is silent in many species but diseases can occur in the reservoir hosts as well as incidental recipients of cross species transmission. It is becoming apparent that cats, who are the reservoir host for at least 5 Bartonella species, develop chronic inflammatory diseases due to their long duration of bacteremia. The most frequently occurring human Bartonella-induced disease is cat scratch disease which is caused by at least 2 Bartonella 56b,89,103,104,113,130,134,138,145 species. Bartonella quintana, the louse-borne agent of trench fever, was responsible for high morbidity among 27 Allied and Axis troops in France in World War I. Bartonella elizabethae has recently been identified as a new member of the group and was isolated from people 36 with endocarditis as well as cats in Sweden. Lawrence 21,22 River and recently dogs with endocarditis, has also been associated with human endocarditis. The list of Bartonella diseases in cats and humans is increasing rapidly (Table 5). Bartonella henselae and Bartonella 56b,89,103,104,113,130,134,138,145 clarridgeiae have been shown to cause cat scratch disease. Although named for its association with exposure to cats, the transmission of these bacteria from cats to humans has not been studied in detail until recently. In 1994 an important study was 75 published which described the finding that the pet cat serves as a reservoir and the cat flea as vector(s) for Bartonella henselae. Cat scratch disease affects an estimated 22,000 people annually, resulting in 2,000 hospitalizations, in the United States and many cases go 119,122 undiagnosed or misdiagnosed each year because of atypical clinical presentations. More recently Bartonella quintana has been found to cause endocarditis in homeless inner city 27,42,133 men. Both bacteria are most likely transmitted by arthropod vectors from natural animal reservoirs to humans, cat fleas for B. The increasing occurrence of both of these bacteria in the inner cities may be due to the increase in poverty and homelessness, which increases the likelihood of arthropod vectors in these populations due to poor personal hygiene. Present research is aimed at identifying Bartonella-infected animals (cats and dogs) and people so that appropriate measures can be instituted to prevent infection of susceptible people from infected "carrier" animals and to treat people who are infected with these bacteria. However, most Bartonella infected pet cats show 32,33,53,57,71,75,111,141 no clinical signs of their infections. Bartonella adhere to endothelial cells in highly vascular tissues such as the oral cavity, respiratory membranes, gastrointestinal tract and ocular tissues where they induce chronic lymphocytic-plasmacytic 13,37,38,50,66,87,88,146 inflammation. Transient neurological dysfunction and other abnormalities have also 1,54,55,56,94,99,143,144 been observed in experimentally infected cats.
