[Cryptococcal meningitis and neuropsychiatric consequences of HIV-infection]. / Cryptokokkenmeningitis en neuro-psychiatrische gevolgen van hiv-besmetting.

A 49-year-old African-born male was admitted to hospital with an acute psychosis. He had been treated by an internist after being found to have hiv; as a result of non-compliance over a period of about four months his cd4-count had dropped to 40. Six months earlier he had developed a cryptococcal meningitis, which left him a number of neurological and psychiatric symptoms. During his stay in hospital there had to be good collaboration with the specialist in internal medicine whose dual task was to manage the patient's dramatically low cd4-account as well as his psychosis. Cryptococcal meningitis is a risk factor for psychiatric disorders and mortality in hiv-infected persons.

[Clozapine and selective serotonin reuptake inhibitors: risks of toxicity]. / Clozapine en selectieve serotonineheropnameremmers: risico's op toxiciteit.

A 25-year-old woman, known to have schizoaffective disorder, presented with symptoms that had arisen a few weeks earlier. The symptoms indicated that she had a toxic clozapine blood level. The probable cause of the toxicity was a pharmacokinetic interaction between citalopram and clozapine at the level of the cytochrome P450 system. A literature search reveals the importance of monitoring the interactions between selective serotonin reuptake inhibitors and clozapine, a procedure which should, if possible, be accompanied by blood level measurements. Caution is called for, particularly when non-smokers are involved.
