The clinical features of PCP differ according to the factors responsible for the predisposing immunosuppression. Although the diagnosis of PCP often requires BAL, the profiles of the inflammatory mediators in the BAL fluid are not thoroughly documented. The aim of the current study was to characterize the profiles of inflammatory mediators in BAL fluid during PCP in patients with underlying autoimmune diseases, malignancies, or AIDS. The medical records of 14 patients with autoimmune diseases, 10 with malignancies, and 8 with AIDS, all of whom had been diagnosed with PCP by microscopic examination of BAL fluid, were reviewed. The concentrations of TNF-alpha, MCP-1, HMGB1, IL-8, IL-6, IL-10, and IFN-gamma in the BAL fluid that had been obtained for the diagnosis of PCP were measured. The concentrations of MCP-1, IL-8, and IL-6 differed according to the underlying disease, tending to be higher in patients with autoimmune diseases and lower in those with AIDS. The concentrations of HMGB1, IL-8, and IL-6 were positively correlated with the proportion of neutrophils in BAL fluid and inversely with the oxygenation index. Although the serum concentrations of CRP and LDH were positively correlated with those of IL-8 and MCP-1, none of the mediators in BAL fluid was correlated with the serum beta-D-glucan concentration. The production of inflammatory mediators in the lung differed between the patient groups with different underlying disorders. The modest upregulation of IL-8 and IL-6 might be associated with the milder clinical manifestations of PCP in AIDS patients.

Pneumocystitis may cause fatal pneumonia in premature, seriously ill infants at intensive care units. The present study evaluated the routine treatment applied at Sohag pediatrics department for neonatal and infantile pneumonia (in NICU & PICU) on PCP and to compare between the stained slides and real time-PCR in diagnosing Pneumocystis jirovecii. Sucked sputum from 21 pneumonic infants was collected, some for Giemsa stain and microscopic examination and the rest for PCR. The same procedure was done after regression of the symptoms and before release from the units. Serum samples were also collected on admission and discharge for CRP readings which was also used as an indicative of the healing process. Out of 21 pneumonic neonates and infants examined, 12 (57.1%) showed P. jirovecii in sputum samples with a significant difference between both groups (p=0.2). 10 of them (83.3%) became negative for P. jirovecii under the routine regimen of treatment. Also 2 cases were infected with microspora, both improved at the end of treatment. While real time PCR was negative in all cases pre and post treatment. CRP levels regressed after treatment in all cases except 2 as one showed post treatment P. jirovecii in the sputum.
