Cryptococcal meningitis is a severe infection in both immunocompetent and immunosuppressed hosts. This report is an unusual case of co-infection with cryptococcal meningitis and Japanese encephalitis in a seronegative human immunodeficiency virus patient. A 51-year-old human immunodeficiency virus-negative patient presented with high-grade fever, nausea, vomiting, and later on, behavioral changes. A lumbar puncture was performed and cerebrospinal fluid revealed the presence of Cryptococcus and Japanese encephalitis virus. Treatment commenced with intravenous amphotericin B and flucytosine. Her condition initially improved but later on deteriorated due to bacteremia (MRSA-mecA gene positive) and septic shock which resulted in the patient’s demise. The occurrence of this co-infection in the absence of HIV infection is rare and there was no documented case up to this date.

Objective To analyze the CT characteristics of consolidation type of pulmonary cryptococcosis in immunocompetent patients,and thus improve the diagnosis of this disease. Methods A total of 20 cases with consolidation-type pulmonary cryptococcosis confirmed by pathological examinations were studied.Each patient underwent breath-hold multislice spiral CT,and 10 patients underwent contrast enhanced CT.The data including lesion number,lesion distribution,lesion density,performance of enhanced CT scan,accompanying signs,and prognosis were analyzed. Results The occurrence rates of single and multiple lesions were 80.0%(n=16)and 20.0%(n=4),respectively.In all the 16 multiple-lesion patients,the occurrence rate of unilateral lobar distribution was 56.0%(n=9).The 76 measurable lesions mainly presented subpleural distribution(71.1%,n=54)and lower pulmonary distribution(75.0%,n=57).A total of 39 lesions were detected in the 10 patients received contrast enhanced CT,in which 31 lesions(79.5%)showed homogeneous enhancement,34 lesions(87.2%)showed moderate enhancement,and all the lesions manifested angiogram sign.Consolidation lesions were accompanied by many CT signs,of which air bronchogram sign had the occurrence rate of 63.2%(n=48),including types Ⅲ(n =37)and Ⅳ(n=11).Other signs included halo signs(43/76,56.6%),vacuoles or cavities(9/76,11.8%),pleural thickening(14/20,70.0%),and pleural effusion(2/20,10.0%).After treatment,the lesions of 7 patients were basically absorbed and eventually existed in the form of fibrosis. Conclusions The lesions in the immunocompetent patients with consolidation type of pulmonary cryptococcosis usually occur in the lower lobe and close to the pleura,mainly presenting unilateral distribution.The CT angiogram signs,proximal air bronchogram signs,and halo signs are the main features of this disease,which contribute to the diagnosis.

BACKGROUND: Cryptococcal meningitis (CM) is one of the most common opportunistic infections caused by Cryptococcus neoformans in human immunodeficiency virus (HIV)-infected patients, and is complicated with significant morbidity and mortality. This study retrospectively analyzed the clinical features, characteristics, treatment, and outcomes of first-diagnosed HIV-associated CM after 2-years of follow-up. METHODS: Data from all patients (n = 101) of HIV-associated CM hospitalized in Shanghai Public Health Clinical Center from September 2013 to December 2016 were collected and analyzed using logistic regression to identify clinical and microbiological factors associated with mortality. RESULTS: Of the 101 patients, 86/99 (86.9%) of patients had CD4 count <50 cells/mm, 57/101 (56.4%) were diagnosed at ≥14 days from the onset to diagnosis, 42/99 (42.4%) had normal cerebrospinal fluid (CSF) cell counts and biochemical examination, 30/101 (29.7%) had concomitant Pneumocystis (carinii) jiroveci pneumonia (PCP) on admission and 37/92 (40.2%) were complicated with cryptococcal pneumonia, 50/74 (67.6%) had abnormalities shown on intracranial imaging, amongst whom 24/50 (48.0%) had more than one lesion. The median time to negative CSF Indian ink staining was 8.50 months (interquartile range, 3.25-12.00 months). Patients who initiated antiretroviral therapy (ART) before admission had a shorter time to negative CSF Indian ink compared with ART-naïve patients (7 vs. 12 months, χ = 15.53, P < 0.001). All-cause mortality at 2 weeks, 8 weeks, and 2 years was 10.1% (10/99), 18.9% (18/95), and 20.7% (19/92), respectively. Coinfection with PCP on admission (adjusted odds ratio [AOR], 3.933; 95% confidence interval [CI], 1.166-13.269, P = 0.027) and altered mental status (AOR, 9.574; 95% CI, 2.548-35.974, P = 0.001) were associated with higher mortality at 8 weeks. CONCLUSION This study described the clinical features and outcomes of first diagnosed HIV-associated CM with 2-year follow-up data. Altered mental status and coinfection with PCP predicted mortality in HIV-associated CM.

The prevalence of asymptomatic cryptococcal antigenemia (ACA) in human immunodeficiency virus (HIV) infected individuals has been observed to be elevated. The prevalence of ACA ranges from 1.3% to 13%, with different rates of prevalence in various regions of the world. We reviewed studies conducted internationally, and also referred to two established expert consensus guideline documents published in China, and we have concluded that Chinese HIV-infected patients should undergo cryptococcal antigen screening when CD4 T-cell counts fall below 200 cells/μL and that the recommended treatment regimen for these patients follow current World Health Organization guidelines, although it is likely that this recommendation may change in the future. Early screening and optimized preemptive treatment for ACA is likely to help decrease the incidence of cryptococcosis, and is lifesaving. Further studies are warranted to explore issues related to the optimal management of ACA.

Introduction: Cryptococcosis is an opportunistic fungal infection caused by Cryptococcus neoformans. This systemic fungal infection affects 6 to 13% of patients with acquired immunodeficiency syndrome (AIDS). Only 10% of patients with this condition develop cutaneous manifestations. Case Summary: A 20-year-old male, newly diagnosed case of HIV (Human Immunodeficiency Virus), presented with multiple skin-colored molluscum contagiosum-like umbilicated papules on the face, neck and both arms. Lesions increased in number rapidly and were associated with respiratory distress. Histopathologic examination revealed findings of opportunistic fungal infection suggestive of cryptococcosis. Serum Cryptococcal Antigen Latex Agglutination System (CALAS) test was also positive. Patient was then diagnosed as a case of cryptococcosis and was a candidate for intravenous amphotericin B. However, before the planned medication was given, the patient experienced severe respiratory distress and expired several hours later. Conclusion Molluscum-like skin lesions may be a telltale sign of a disseminated opportunistic fungal infection, including Cryptococcosis. Early diagnosis followed by prompt and aggresive treatment would improve outcome and survival of the patient.

Introduction: Cryptococcus neoformans (C. neoformans) is a fungus which infects the lungs, meninges, skin and the nervous system. In tropical countries prevalent with tuberculosis (TB), initial clinical presentations of a C. neoformans infection can normally be mistaken as a TB infection. The C. neoformans infection shall then form part of the differential diagnosis. Exposure to C. neoformans does not usually manifest as an infection however, in immunocompromised patients this results to cryptococcosis. Case: This is a case of a 33-year-old male who was admitted due to febrile seizures. He was suspected to be in an immunocompromised state due to multiple sexual partners. A non-tender, mobile left cervical lymphadenopathy was subjected to FNAB (fine needle aspiration biopsy) surprisingly came out to be cryptococcal in nature. He was managed as a case of disseminated cryptococossis with meningeal extension. He was given amphotericin B and fluconazole. Conclusion The most common suspected cause of lymphadenitis in the Philippines is attributed to TB. The high index of suspicion based on sound medical history and physical examination can lead the clinician into considering an uncommon cause of lymphadenopathy most especially in patients with high likelihood of immunocompromised state.

To investigate the clinical characteristics and prognosis for connective tissue disease (CTD) with cryptococcal meningitis (CM). 
 Methods: Clinical data of 18 patients with CTD complicated with cryptococcal meningitis diagnosed by Rheumatology and Immunology Department, Xiangya Hospital, Central South University from January 2000 to January 2017, were retrospectively analyzed.
 Results: The common symptoms of CTD patients with CM were headache, fever, nausea, and vomiting. Patients with severe clinical manifestations, such as convulsions and disturbance of consciousness, all died. Logistic regression analysis showed that disturbance of consciousness and decreased peripheral blood lymphocyte count might be the related factors of poor prognosis of CTD patients with CM (P<0.05). The mortality rate of CTD with CM was 61.11%, and the effective rate of treatment for this disease was 38.89%.
 Conclusion: CTD patients with cryptococcal meningitis have a high risk of death. Severe clinical symptoms, such as disturbance of consciousness and lower peripheral blood lymphocyte count, are associated with its poor prognosis.
