History

Hemophilia is suggested by a history of hemorrhage disproportionate to trauma or of spontaneous hemorrhage, or a family history of bleeding problems. Concomitant illness may include chronic inflammatory disorders, autoimmune diseases, hematologic malignancies (acquired form), and allergic drug reactions.

For individuals with documented hemophilia, inquire regarding the type of deficiency (eg, VIII, IX, von Willebrand), percent factor deficiency, known presence of inhibitors, and HIV/hepatitis status.

Approximately 30-50% of patients with severe hemophilia present with manifestations of neonatal bleeding (eg, after circumcision). Approximately 1-2% of neonates have intracranial hemorrhage. Other neonates may present with severe hematoma and prolonged bleeding from the cord or umbilical area or at sites of blood draws or immunizations.

After the immediate neonatal period, bleeding is uncommon in infants until they become toddlers, when trauma-related soft-tissue hemorrhage occurs. Young children may also have oral bleeding when their teeth are erupting. Bleeding from gum and tongue lacerations is often troublesome because the oozing of blood may continue for a long time despite local measures.

As physical activity increases in children, hemarthrosis and hematomas occur. Chronic arthropathy is a late complication of recurrent hemarthrosis in a target joint. Traumatic intracranial hemorrhage is a serious life-threatening complication that requires urgent diagnosis and intervention.

With mild disease, hemorrhage is most likely to occur with trauma or surgery. A traumatic challenge relatively late in life may have to occur before mild or moderate hemophilia is suspected.

Signs of hemorrhage include the following:

General - Weakness and orthostasis
Musculoskeletal (joints) - Tingling, cracking, warmth, pain, stiffness, and refusal to use joint (children)
CNS - Headache, stiff neck, vomiting, lethargy, irritability, and spinal cord syndromes
GI - Hematemesis, melena, frank red blood per rectum, and abdominal pain
Genitourinary - Hematuria, renal colic, and postcircumcision bleeding
Other - Epistaxis, oral mucosal hemorrhage, hemoptysis, dyspnea (hematoma leading to airway obstruction), compartment syndrome symptoms, and contusions

Joint and muscle hemorrhage are the most common manifestations of moderate and severe hemophilia. Petechiae usually do not occur in patients with hemophilia because they are manifestations of capillary blood leaking, which is typically the result of vasculitis or abnormalities in the number or function of platelets.

Signs of infectious disease include the following:

HIV/AIDS-related symptoms
Hepatitis-related symptoms

The principal sites of bleeding in patients with hemophilia are as follows. Bleeds affect weight-bearing joints and other joints. The muscles most commonly affected are the flexor groups of the arms and gastrocnemius of the legs. Iliopsoas bleeding is dangerous because of the large volumes of blood loss and because of compression of the femoral nerve.

In the genitourinary tract, gross hematuria may occur in as many as 90% of patients. In the GI tract, bleeding may complicate common GI disorders. Bleeding in the CNS is the leading cause of hemorrhagic death among patients with hemophilia.

Physical Examination

Systemic signs of hemorrhage include the following:

Tachycardia
Tachypnea
Hypotension
Orthostasis

Organ system–specific signs of hemorrhage include the following:

Musculoskeletal (joints) - Tenderness, pain with movement, decreased range of motion, swelling, effusion, and warmth
CNS - Abnormal neurologic exam findings, altered mental status, and meningismus
GI - Can be painless; hepatic/splenic tenderness and peritoneal signs
GU - Bladder spasm/distension/pain, costovertebral angle pain
Other - Hematoma leading to location-specific signs (eg, airway obstruction, compartment syndrome)

Signs of infectious disease include the following:

HIV/AIDS-related signs
Hepatitis-related signs

Direct the examination to identify signs related to bleeding in the joints, muscles, and other soft tissues that has occurred spontaneously or after minimal challenge. Observe the patient's stature. Examine the weight-bearing joints, especially the knees and ankles, and, in general, the large joints for deformities or ankylosis. Look for jaundice, other signs of liver failure (eg, cirrhosis from viral infection), and signs of opportunistic infections in patients who are HIV seroconverted.

Clinical Classification

Hemophilia is classified according to the clinical severity as mild, moderate, or severe (see Table 1, below). Patients with severe disease usually have less than 1% factor activity. It is characterized by spontaneous hemarthrosis and soft tissue bleeding in the absence of precipitating trauma. Patients with moderate disease have 1-5% factor activity and bleed with minimal trauma. Patients with mild hemophilia have more than 5% factor VIII (FVIII) activity and bleed only after significant trauma or surgery.
