Renal (kidney) involvement is common, occurring in 30-70 % of patients. Kidney disease is usually noted after the onset of systemic symptoms. More marked findings may also occur including nephrotic syndrome, a situation characterized by abnormal excretion of proteins and lipids in urine, swelling (edema), low level of albumin in blood and hyperlipidemia. High blood pressure (hypertension) and acute kidney failure may also be seen. Worsening of the kidney symptoms and biopsy-confirmed worsening of the kidney lesions may be observed in patients with repeated attacks of rash or hematuria (blood in the urine).
PCP has also been shown to cause schizophrenia-like changes in N -acetylaspartate and N -acetylaspartylglutamate levels in the rat brain, which are detectable both in living rats and upon necropsy examination of brain tissue.  It also induces symptoms in humans that mimic schizophrenia.  PCP not only produced symptoms similar to schizophrenia, it also yielded electroencephalogram changes in the thalamocortical pathway (increased delta decreased alpha) and in the hippocampus (increase theta bursts) that were similar to those in schizophrenia.  PCP induced augmentation of dopamine release may link the NMDA and DA hypothesis of schizophrenia. 
We report 3 cases of pneumocystis pneumonia (PCP) in patients with advanced cancer who received palliative care. All patients received long-term steroid therapy for symptom management. A diagnosis of PCP was based on clinical symptoms and a positive Pneumocystis jiroveci polymerase chain reaction test from induced sputum specimens. Despite appropriate treatment, only 1 patient recovered from PCP. Long-term steroid, often prescribed in palliative care settings, is the most common risk factor for PCP in non-HIV patients. Pneumocystis pneumonia may cause distressing symptoms such as severe dyspnea, and the mortality rate is high. Therefore, it is important to consider PCP prophylaxis for high-risk patients and to diagnose PCP early and provide appropriate treatment to alleviate PCP-related symptoms and avert unnecessary shortening of a patient's life expectancy.
