Insights

This study on Paracoccidioidomycosis in children found that juvenile and disseminated forms are common, often presenting with fever, enlarged lymph nodes, anemia, and eosinophilia. Treatment with sulfametoxazole-trimethoprim showed significant improvement in lab markers within six months.

Area of Science:

  • Pediatric Infectious Diseases
  • Mycology
  • Clinical Medicine

Background:

  • Paracoccidioidomycosis (PCM) is a systemic fungal infection endemic in Latin America.
  • Juvenile and disseminated forms of PCM are frequently observed in children.
  • Understanding the clinical spectrum and treatment outcomes in pediatric populations is crucial.

Purpose of the Study:

  • To describe the clinical manifestations, laboratory findings, and treatment outcomes of Paracoccidioidomycosis in children under 15 years old.
  • To evaluate the effectiveness of sulfametoxazole-trimethoprim as a first-line treatment.
  • To identify prognostic factors and sequelae in pediatric PCM cases.

Main Methods:

  • Retrospective analysis of 70 episodes of PCM in 63 children (ages 2-15) admitted between 1981 and 2001.
  • Clinical and laboratory data collected upon admission, including physical examination, blood counts, and biochemical tests.
  • Radiographic and technetium studies for bone lesion assessment.
  • Treatment with sulfametoxazole-trimethoprim in 50 episodes, with follow-up of clinical and laboratory parameters.

Main Results:

  • Common presentations included lymph node enlargement (87.1%), fever (75.7%), anemia (90%), hypergammaglobulinemia (88.5%), and eosinophilia (75.5%).
  • Moderate to severe malnutrition was present in 35.7% of cases.
  • Bone lesions were observed in 20 episodes.
  • Sulfametoxazole-trimethoprim treatment led to significant improvement in hemoglobin, eosinophil, albumin, and gammaglobulin levels within six months.
  • Mortality rate was 9.3%, and 6.3% developed sequelae.

Conclusions:

  • Juvenile and disseminated forms of PCM are prevalent in children, often presenting as a febrile lymphoproliferative syndrome.
  • Anemia, eosinophilia, and hypergammaglobulinemia are key laboratory findings.
  • Sulfametoxazole-trimethoprim is an effective first-line treatment, with laboratory markers useful for monitoring therapeutic response.

Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Chronic Obstructive Pulmonary Disease IV: Clinical Manifestations

Chronic Obstructive Pulmonary Disease, or COPD, is a long-term condition marked by persistent and only partially reversible airflow limitation. It involves two overlapping conditions—chronic bronchitis and emphysema—which often co-appear but differ in dominant symptoms and underlying mechanisms.Chronic Bronchitis FeaturesChronic bronchitis presents with a persistent productive cough and thick, sometimes purulent mucus due to airway inflammation, enlarged mucus glands, and goblet cell...
Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
