Abstract
The menace of cryptococcosis has assumed global proportions over the years. The tropical climate of the Indian subcontinent offers a suitable environment for Cryptococcus neoformans, and the onslaught of the acquired immune deficiency syndrome (AIDS) pandemic since the early 1990s has substantially influenced the situation. Coupled with that are the advances in laboratory diagnostic techniques that have made accurate diagnosis increasingly available. These factors together have led to a sharp increase in the number of reported cases of cryptococcosis. This review attempts to present an overview of the status of cryptococcosis in India from its first description to the most recent times. The disease has been reported from almost all parts of the country. C. neoformans var. neoformans is predominantly found in clinical samples, while C. n. var. gattii infection has also been reported. An organ commonly involved is the central nervous system, among others. Both immunocompromised and apparently immunocompetent patients have been affected. Laboratory diagnosis is mostly by conventional methods, while effective therapeutic options are limited. Early diagnosis followed by institution of specific therapy, where possible, has effectively reduced mortality. Awareness of the disease and maintenance of a high index of clinical suspicion is required. An integrated approach to patient management with active interaction between the clinicians and the laboratory personnel would be highly beneficial. The wide variety of presentations of the disease seen in India suggests the possibility of occurrence of strain variation which needs to be investigated fully. Introduction of routine testing of antifungal susceptibility of clinical isolates is also important in order to obtain baseline data on susceptibility patterns and to predict in advance any shift in those patterns in the population. To maintain a high standard in all such endeavours, the establishment of an external quality control system is desirable.
