Cryptococcosis at the University Hospital, Kuala Lumpur

Abstract:
We review our experience with 27 cases of pulmonary and meningeal cryptococcosis at the University Hospital, (Kuala Lumpar, Malaysia) where this is the most common cause of adult meningitis in patients without debilitating illnesses. Of the 27 cases analysed, six presented primarily with pulmonary symptomatology which usually were mainly cough, chest pain and low grade fever. The rest presented with primarily central nervous system (CNS) symptomatology of which headaches and fever were the most consistent symptoms although a third of these patients also had pulmonary lesions noted on chest radiographs. Treatment in all cases was with amphotericin B and 5-fluorocytosine and usually till a total cumulative dose of 1.5 g of amphotericin had been reached (an average of 10 weeks). Primary pulmonary presentations, if symptomatic, were treated as per CNS cryptococcosis due to the high likelihood of CNS dissemination. Incidental pulmonary cryptococcoma found on routine chest radiographs were confirmed by biopsy under ultrasound or fluoroscopy guidance and booked for surgical resection. Death usually occurred early in patients who presented late. Once patients responded to therapy, mortality was usually avoided. The only cause of morbidity in survivors was visual impairment or blindness, and this was attributed mainly to intracranial hypertension with residual deficits determined by the measures taken to lower intracranial pressures. Our experience suggests that: (i) symptomatic patients should have combination therapy with 5-fluorocytosine and amphotericin B till at least a cumulative dose of 1.5 g amphotericin B is reached irrespective of whether they have primary CNS or pulmonary symptomatology; (ii) non-symptomatic pulmonary cryptococcoma could be treated primarily by surgical resection; (iii) visual failure or papilloedema should be treated aggressively; and (iv) prognosis is good with adequate therapy and early presentation.
Insights
Combination therapy with amphotericin B and 5-fluorocytosine is effective for pulmonary and meningeal cryptococcosis. Early presentation and aggressive treatment of intracranial hypertension improve outcomes, while asymptomatic pulmonary cryptococcoma may be surgically resected.
Area of Science:
- Infectious Diseases
- Mycology
- Neurology
Background:
- Cryptococcosis, particularly pulmonary and meningeal forms, is a significant cause of meningitis in immunocompetent adults in Malaysia.
- Pulmonary cryptococcosis often presents with respiratory symptoms, while central nervous system (CNS) involvement is characterized by headaches and fever.
Purpose of the Study:
- To review the experience with pulmonary and meningeal cryptococcosis cases.
- To evaluate treatment strategies and outcomes for cryptococcosis.
- To identify factors influencing prognosis and morbidity.
Main Methods:
- Retrospective analysis of 27 cases of pulmonary and meningeal cryptococcosis.
- Treatment involved combination therapy with amphotericin B and 5-fluorocytosine.
- Surgical resection for incidental pulmonary cryptococcoma.
Main Results:
- Combination therapy achieved good outcomes, with mortality avoided in responsive patients.
- Early presentation and treatment were associated with better prognosis.
- Visual impairment/blindness was the main morbidity, linked to intracranial hypertension.
Conclusions:
- Symptomatic cryptococcosis requires combination therapy with amphotericin B and 5-fluorocytosine to a cumulative dose of 1.5g.
- Asymptomatic pulmonary cryptococcoma can be managed with surgical resection.
- Aggressive management of visual failure and papilledema is crucial for preventing permanent deficits.
