Study Notes
Digoxin Toxicity
- Digoxin toxicity is uncommon, but can happen in patients treated with digoxin, especially geriatric patients.
- The therapeutic index for digoxin is narrow, and patients with serum concentrations >1.5 ng/mL often show signs of toxicity (even some with normal ranges).
- Digoxin toxicity is a risk factor for renal impairment, so monitor renal function and electrolytes regularly.
- Digoxin dosage should be reduced if renal disease develops.
Discospondylitis
- Discospondylitis is an infection usually caused by bacteria (like Staphylococcus pseudintermedius, Streptococcus, Brucella canis, and Escherichia coli) or fungi.
- The infection happens in the intervertebral end plates, discs, and adjacent vertebral bodies. It can also be caused by migrating foreign bodies.
- The most common area affected is the lumbosacral space.
- The lumbar spine is most likely to be affected.
- Signs of discospondylitis include pain, difficulty rising, reluctance to jump, stilted gait, ataxia, paresis, and lameness.
- Diagnose discospondylitis with spinal radiographs, urine cultures, and blood cultures.
- Myelography should be performed with substantial neurologic deficits to determine the location of the lesion.
- Treatment with antibiotics should be tailored to the specific organism causing the infection.
- Treat patients with supportive care, including comfortable bedding to prevent decubital ulceration.
Fever
- Fever is often caused by infectious diseases like FIV, FeLV, Toxoplasmosis, Borrelia, Mycoplasma, Bartonella, Anaplasma, Ehrlichia, Rickettsia, FIP, and systemic mycoses.
- Fever can also be caused by non-infectious diseases such as immune-mediated disease and certain tumors (e.g., lymphoma).
- Glucocorticoids should be used with caution and should only be utilized to treat fever after infectious causes have been ruled out.
- Glucocorticoids can mask clinical signs, immunosuppress the patient, and interfere with diagnosis and treatment.
- Antipyretics should be used with caution in patients with impaired organ function and only when fever is prolonged and life-threatening.
- Antipyretics can cause emesis, diarrhea, gastrointestinal ulceration, and renal complications.
### Fiber-Responsive Large Bowel Diarrhea in Dogs
- Occurs in dogs of all ages, with median age of 6 years
- More common in German shepherd, miniature schnauzer, cocker spaniel, miniature or toy poodle
- Diarrhea is chronic, soft to liquid, often with mucus, blood, increased frequency, and urgency
- Can be episodic, alternating with periods of normal stool
- 25% of dogs have continuous diarrhea
- Other signs include occasional vomiting, decreased appetite during episodes
- Cause likely unknown, may be related to stress, abnormal personality traits, motility and/or dysbiosis
- Responds to dietary soluble fiber supplementation
Pathophysiology
- Dysbiosis is defined as microbial imbalance in the gastrointestinal tract
- In dogs, soluble fiber is a prebiotic that is fermented by colonic bacteria, altering microbial composition or activity
- Causes
- Clostridium perfringens
- Lymphocytic plasmacytic colitis
- Eosinophilic colitis
- Miscellaneous types of colitis
- Irritable bowel syndrome
- Colonic neoplasia (adenocarcinoma, lymphoma, adenoma)
- Cecal inversion
Diagnosis
- No consistent or specific abnormalities in CBC, Biochemistry, or Urinalysis
- Multiple fecal flotations by zinc sulfate to rule out parasites
- Abdominal radiographs are usually within normal limits
- Colonoscopy can also be performed, but usually within normal limits or only mild nonspecific findings
Treatment
- Treatment focuses on dietary fiber supplementation
- Hypoallergenic diet trial for 2-3 weeks
- If no improvement in stool quality, further investigation needed
- During food trial, no other supplements/nutrients should be given
Other Key Points
- Pathologic findings
- Histopathologic evaluation of colonic biopsy samples usually within normal limits
- Multiple biopsy samples should be taken from the cecum to the rectum
- Activity level does not have to be modified during treatment
Disseminated Intravascular Coagulation (DIC)
- DIC is an acquired hemostatic defect resulting from various inciting causes that leads to intravascular activation of coagulation and consumption of clotting factors.
- The disorder results in widespread formation of microthrombi with clinical manifestations of thrombosis and/or hemorrhage.
- Non-overt DIC is the early, compensated form of DIC, featuring consumption of coagulation factors and generation of microthrombi without clear clinical signs.
- Overt DIC is the classic phenotype associated with hemorrhage, thrombosis, and organ failure.
Causes
- DIC is a complication of a variety of primary conditions.
- It begins with a hypercoagulable state that leads to production or embolization of microthrombi in small vessels.
- Common causes include:
- Gastric dilatation-volvulus
- Heart failure
- Heartworm disease
- Heat stroke
Signalment
- Primarily diagnosed in dogs.
- More common in dogs than cats.
- No significant breed predilection.
- Age and sex are dependent on underlying disease.
Signs
- Vary with primary disease and DIC-associated organ dysfunction.
- May include:
- Petechiae
- Bleeding from venipuncture sites, mucosa, or into body cavities.
- Bleeding is infrequent in cats.
Incidence/Prevalence
- Associated with severe systemic inflammatory disease.
- Suspect DIC any time thrombocytopenia and prolonged clotting tests are seen together.
Diagnosis
- Laboratory monitoring every 24-48 hours is recommended for patients with predisposing conditions.
- A sudden drop in platelet count and a 20-30% prolongation in APTT is suspicious for non-overt DIC.
- CBC/biochemistry/urinalysis may show:
- Inflammatory leukogram, often with a stress component.
- Mild to moderate thrombocytopenia (40-100 × 103/μL); less reliable in cats.
- Anemia is possible.
- Red blood cell (RBC) fragmentation is a supportive finding.
- Biochemical changes reflect affected organs; acute kidney injury may result in increased FDP values.
Differential Diagnosis
- Hepatic insufficiency may mimic DIC.
- Mild idiopathic thrombocytopenia may also be seen.
- Spontaneous bleeding is uncommon unless DIC is present.
Treatment
- Early intervention is critical to prevent progression to overt DIC.
Prognosis
- Variable, depending on the etiology and response to treatment.
- Mortality rate can be high, especially in cases of overt DIC.
Digoxin Toxicity
- Digoxin toxicity is not uncommon in patients treated with digoxin due to its narrow therapeutic index and prevalence of renal impairment in elderly patients with cardiac disease.
- Target digoxin levels to be between 0.5 and 1 ng/mL, this minimizes the risk of toxicity.
- Monitor ECG periodically to assess for conduction disturbances (AV block, arrhythmias, and ST segment depression).
Disseminated Intravascular Coagulation (DIC)
- DIC is a serious condition with a guarded to poor prognosis.
- Usually there is no specific pharmacologic therapy for DIC itself.
- Key positive findings for DIC are clinical improvement and arrest of bleeding.
- Daily lab testing (coagulation tests, fibrinogen, platelet counts) is warranted in severe cases.
- Heparin may be used in patients with overt thrombosis or those at high risk of thrombosis, with normal coagulation times.
Colitis
- Colitis is a common condition in dogs of all ages, with a median age of 6 years.
- German Shepherd, Miniature Schnauzer, Cocker Spaniel, and Miniature or Toy Poodle breeds are commonly affected.
- Chronic diarrhea (soft to liquid) with large bowel characteristics, tenesmus, excess fecal mucus, hematochezia, increased frequency and urgency, and periods of normal stool are key clinical signs.
- No consistent or specific abnormalities are found in CBC/BIOCHEMISTRY/URINALYSIS, although peripheral eosinophilia may be seen in some cases.
- Multiple fecal flotations are essential for diagnosis and to rule out other causes, such as whipworms and other parasites.
- Dietary fiber supplementation and appropriate activity levels are key components of treatment.
- Multiple biopsies from throughout the colon are necessary for accurate histopathologic evaluation.
