Mumps Virus Orchitis: An Obsolete Complication

Orchitis, an inflammation of the testicles, was a common complication of mumps virus infection in postpubertal males. According to various sources [1][3][5], it occurred in as many as 50% of postpubertal males who contracted the virus.

Symptoms and Consequences

The symptoms of orchitis caused by mumps virus included sudden swelling, pain, and warmness of a testis [2]. In some cases, this complication could lead to more severe consequences such as:

• Shrinkage of the testicles (testicular atrophy) [6]
• Infertility [6]

Prevalence and Causes

Before widespread vaccination against mumps virus, orchitis was a significant concern among unvaccinated males. Approximately 1 in 3 unvaccinated males who contracted mumps after puberty developed orchitis [5].

Orchitis can be caused by various factors, including infections such as epididymitis [8]. However, in the context of mumps virus infection, it was a well-documented complication.

Orchitis, a Complication of Mumps Virus Infection

Mumps virus orchitis, also known as testicular inflammation, is a rare but serious complication of mumps infection. The signs and symptoms of orchitis caused by the mumps virus are:

• Testicular pain: Pain in one or both testicles is the most common symptom of orchitis.
• Swelling: Swelling of the affected testicle(s) can occur, which may be accompanied by redness and tenderness.
• Fever: Some individuals with orchitis caused by mumps virus may experience fever, although this is not a universal symptom.
• Loss of appetite: Feeling tired or experiencing loss of appetite are also possible symptoms.

Complications

In some cases, orchitis caused by the mumps virus can lead to more severe complications, including:

• Testicular atrophy: Shrinkage of the affected testicle(s) may occur in some individuals.
• Infertility: Although rare, orchitis caused by the mumps virus has been linked to infertility in some cases.

Important Notes

It's essential to note that orchitis is a relatively rare complication of mumps infection. According to various sources [1][2], orchitis occurs in approximately 50% of postpubertal males who contract mumps, and it can develop anywhere from four to ten days after the salivary glands swell.

Diagnostic Tests for Obsolete Mumps Virus Orchitis

Orchitis, an inflammation of one or both testicles, caused by the mumps virus is a rare condition in today's era due to widespread vaccination. However, when it does occur, diagnosis can be confirmed through various tests.

• Serology: Enzyme immunoassay for mumps immunoglobulin antibodies are most commonly used for diagnosis [5]. This test detects the presence of antibodies against the mumps virus in the blood.
• Virus Culture: The microbiological diagnosis is by serology or virus culture [5]. This test involves growing the virus from a sample, such as saliva or seminal fluid, to confirm its presence.
• Reverse Transcription Polymerase Chain Reaction (RT-PCR): Real-time RT-PCR is the preferred method to confirm mumps; it's more sensitive and specific than serologic assays to detect IgM [10]. This test detects the genetic material of the virus in a sample.
• Viral Culture: Testing should be performed when the patient’s viral load is at its peak (≤3 days from the onset of symptoms) to minimize the risk of a false-negative result [3].
• Doppler Ultrasonography: Urgent differentiation of orchitis from testicular torsion and other causes of acute scrotal swelling and pain is accomplished with color Doppler ultrasonography [13]. This non-invasive imaging test measures blood flow to your testicles.

These diagnostic tests can help confirm the presence of mumps virus orchitis, although laboratory testing is usually not needed to make a diagnosis in typical cases but is strongly recommended for public health purposes [15].

Treatment Options for Obsolete Mumps Virus Orchitis

While mumps virus orchitis has become less common due to routine childhood vaccinations, it's essential to understand the treatment options available.

• No specific antiviral therapy: Currently, there is no specific antiviral therapy available to treat mumps virus orchitis (Source: [2])
• Supportive care: Treatment for mumps virus orchitis typically involves supportive care, such as:
  • Bed rest
  • Scrotal support
  • Local cooling and anti-inflammatory drugs to diminish inflammation and reduce intratesticular pressure (Sources: [6], [7])
  • Pain medications like acetaminophen or ibuprofen for headaches or discomfort due to parotitis (Source: [3])
• No effective treatment: Unfortunately, mumps virus orchitis has no effective treatment, and the outcome can vary. Men who have had mumps orchitis can become sterile (Sources: [4], [9])

It's crucial to note that these treatment options are primarily focused on relieving symptoms and supporting the body's natural recovery process.

Differential Diagnosis of Obsolete Mumps Virus Orchitis

The differential diagnosis for mumps virus orchitis, which was a common cause of orchitis in the past, includes several conditions that can present with similar symptoms. These include:

• Testicular torsion: A medical emergency where the spermatic cord becomes twisted, cutting off blood flow to the testicle. This condition typically presents with abrupt scrotal pain and is a main differential diagnosis for mumps orchitis [3].
• Viral pathologies: Such as uveoparotid fever and coxsackie virus infections, which can cause similar symptoms to mumps orchitis [5].
• Sexually transmitted infections (STIs): Certain STIs, such as gonorrhea and chlamydia, can cause epididymitis, a condition that can present with testicular pain and swelling, similar to mumps orchitis [7].
• Bacterial infections: Various types of bacteria, such as E. coli and Klebsiella pneumoniae, can cause orchitis, which may be confused with mumps virus orchitis in the differential diagnosis [9].

It's worth noting that the incidence of mumps virus orchitis has decreased significantly due to widespread vaccination against the mumps virus.
