Non-neoformans cryptococci were previously considered to be saprophytes and nonpathogenic to humans. Cryptococcus laurentii is frequently used as a biological means to control fruit rot. Interestingly, C laurentii has recently been reported to be a rare cause of infection in humans. The authors report a case of pulmonary cryptococcosis caused by C laurentii in a diabetic AIDS patient who was on antituberculosis and antiretroviral treatments. The sputum smear revealed capsulated yeast cells that were identified as C laurentii. Repeated pleural fluid culture revealed growth of C laurentii. Both respiratory samples were negative for acid-fast bacilli. Moraxella catarrhalis and Klebsiella pneumoniae were also found in the sputum, but not in the pleural fluid. The patient had a good response to oral fluconazole therapy at 600 mg/day for five weeks and was then discharged. The present article is the first to report on the rare pulmonary involvement of C laurentii in the Indian HIV population. These unusual forms of cryptococci create a diagnostic predicament in the rapid diagnosis of pulmonary cryptococcosis. A high degree of suspicion and improvement of techniques for culture and identification will contribute to the early diagnosis and treatment of unusual fungal infections.
HIV-infected children in resource-limited settings are increasingly gaining greater access to highly active antiretroviral therapy (HAART) but documented longitudinal data remains limited. We aimed to study the clinical and immunological outcomes among 67 South Indian HIV-infected children with >18 months of follow-up on HAART at a tertiary HIV care program. The median CD4 cell count at enrolment was 290 cells microl(-1) and at treatment initiation was 225 cells microl(-1). Patients demonstrated a significant rise in their CD4 cell counts between treatment initiation and after 6 months (701 cells microll(-1); p = 0.007), 12 months (741 cells microl(-1); p = 0.037), and 18 months of therapy (718 cells microl(-1); p = 0.005). The most common adverse events to therapy were nausea (20.9%) and rash (25.4%). Over one-fifth of patients (25.4%) substituted therapy due to toxicities and 19.4% of patients switched to second-line protease inhibitor-containing regimens. In this South Indian pediatric cohort, generic HAART was safe, effective and relatively well tolerated.
This case report documents that highly active antiretroviral therapy (HAART) can lead to the regression of Kaposi's sarcoma (KS) lesions in the auditory canal of an HIV-infected male from Chennai, India. In resource-limited settings where administering anti-KS chemotherapeutic agents may not be feasible, HAART alone can be an option in HIV-infected individuals with KS.
Nevirapine is a non-nucleoside reverse transcriptase inhibitor, widely used in combination with other antiretroviral agents for treatment of HIV infection. Steven Johnson syndrome (SJS) is the major toxicity of nevirapine. We describe here four cases of SJS in HIV seropositive patients following nevirapine therapy. In all four cases cutaneous hypersensitivity reaction was seen with extreme oral lesions, three patients presented clinically with elevated liver enzymes and hepatitis, and two patients had ocular involvement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
