Overview
Acute paracoccidioidomycosis (PCM) affects 5% of the patients, and it has a more rapid and severe evolution. Acute PMC primarily compromises the reticuloendothelial system organs.[1][2] Meanwhile, chronic paracoccidioidomycosis represents 90% of the patients and has a slower evolution. Chronic PCM frequently develops pulmonary symptoms which can leave severe sequela.[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 treatment. Without treatment, PCM will result in death due to disease complications. The presence of late diagnosis and sequelae is associated with a particularly poor prognosis among patients with PCM.[6]
Natural History
Latent Paracoccidioides Infection
- Latent paracoccidioides infection can be adquired in the first decade of life.
- PCM latent infection does 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 infection.[1]
- The reticuloendothelial system organs and gastrointestinal tract are involved at this stage of the disease.[1]
- Acute PCM starts with nonspecific symptoms such as fever, weight loss, weakness, anorexia, pallor, etc.
- Patients find swollen lymph nodes in different body regions (cervical, axilar, paravertebral and retroperitoneal ganglia). Digestive, osteoarticular and cutaneous signs and symptoms are found.
- Pulmonary manifestations are rare.[3]
Chronic/Adult
- Chronic paracoccidioidomycosis represents 90% of the disease.
- The symptoms of chronic PCM usually start to develop in the third decade of life, even though the infection 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%).[8][7]
Complications
Paracoccidioidomycosis develops sequelae frequently:
- 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
- Acute PCM is most a critical condition as it has a rapid evolution. Juvenile PCM has higher mortality rates than adult PCM.[2]
- Deaths can ocurre because of: late diagnosis, dissemination of the disease (multifocal) or sequelae.[6]
