Overview
Among all infected patients 5% are acute with a more rapid and severe progression compared to the chronic subtype. Acute PMC primarily affects the reticuloendothelial system organs.[1][2] Meanwhile, chronic paracoccidioidomycosis represents 90% of infected patients and has a slower progression. Patients with chronic PCM frequently develops pulmonary symptoms.[3][4] Complications that can develop as a result of PCM are chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, bullae, pulmonary hypertension, dyspnea, adrenal gland insufficiency, dysphonia, laryngeal lesions (such as glottis estenosis), microstomia, seizures, and motor deficiency.[2][4][5] The prognosis of paracoccidioidomycosis is good with adequate treatment. Without treatment, death is due to PCM related complications.[6]
Natural History
Latent Paracoccidioides Infection
- Latent paracoccidioides infection can be adquired in the first decade of life.
- Patienes with latent PCM infection do not manifest symptoms.[7]
Acute/Subacute/Juvenile
- Acute PCM occurs in children and young adults. It constitutes only 3-5% of PCM disease.[1]
- Symptoms take place weeks or months after the transmission.[1]
- The reticuloendothelial system organs and gastrointestinal tract are usually involved at this stage of the disease.[1]
- Acute PCM starts with nonspecific symptoms such as fever, weight loss, weakness, anorexia, pallor, etc.
- Patients may also report swollen lymph nodes in different body regions (cervical, axilar, paravertebral and retroperitoneal ganglia). Digestive, osteoarticular and cutaneous signs and symptoms may also be present.
- Pulmonary manifestations in the acute for are rare.[3]
Chronic/Adult
- Chronic paracoccidioidomycosis represents 90% of the disease.
- The symptoms of chronic PCM usually start to progress in the third decade of life, even though the organism can be acquired in the first decade of life.[3]
- The symptoms of paracoccidioidomycosis typically develop 20-30 years after exposure to Paracoccidioides spp.
- PCM symptoms develop slowly through the years.
- Patients develop pulmonary symptoms (90%), with or without nonespecific symptoms. Nevertheless, other symptoms can occur such as cutaneous or mucosal lesions (51-82%).[7][8]
- Paracoccidioides can enter the bloodstream and disseminate to CNS and cause neuroparacoccidioidomycosis.[9]
Complications
Acute paracoccidioidomycosis complications include
- Bone marrow failure
Chronic paracoccidioidomycosis complications include
- Chronic obstructive pulmonary disease (COPD)
- Pulmonary fibrosis
- Bullae
- Pulmonary hypertension
- Dyspnea
- Adrenal gland insufficiency
- Dysphonia
- Laryngeal lesions (such as glottis estenosis)
- Microstomia
- Seizures
- Motor deficiency[2][4][5]
Prognosis
- The prognosis varies with the type of infection; chronic PCM have the most favorable prognosis with adequate treatment.
- Juvenile PCM has higher mortality rates than adult PCM.[2]
- Deaths can occur because of late diagnosis, dissemination of the disease (multifocal) or development of complications.[6]
