Studies have shown that for P falciparum, the most effective treatment is artesunate which is more effective than quinine without the risk of cinchonism.

The test of choice is Giesma-stained thick and thin blood smears. Treatment of malaria in pregnancy must be managed with an ID specialist and should be treated with IV antimalarial therapy. falciparum are also susceptible to the complications of pregnancy due to placental parasite sequestration. Therefore those who live in endemic areas may develop minimal symptoms due to IgG antibody and cell-mediated immunity and physiological tolerance of parasitaemia. The severity of malaria depends partly on the species and also on host immunity. Thrombocytopenia is common with falciparum infection and a mild degree of anaemia ais commonly seen. Hepatosplenomegaly is a common presenting sign although not common at presentation in a first world setting. malariae infections but in most patients there is no specific pattern.

The mainstay of treatment for severe disease involves systemic corticosteroids. Black people have a higher lifetime risk of sarcoidosis, as do those of Scandinavian origin.
A transbronchial biopsy is essential for diagnosis in most cases and shows the presence of non-caseating granulomas.
Additionally, serum calcium and ACE levels may be raised. CXR will typically show bilateral hilar lymphadenopathy and CXR findings are used in the staging of disease. Although uncommon, the patient may present with unexplained modest weight loss (which is often mistaken for TB or lymphoma along with the abnormal CXR) and a low-grade fever. Lymphadenopathy is a common presentation and nodes are enlarged but non-tender, typically involving the cervical and submandibular nodes. Sarcoidosis - Sarcoidosis is a chronic multisystem disease with an unknown aetiology.
