60 children with community acquired pneumonia will receive oral coenzymeQ10 in capsule form at a dose of 100-200 mg/kg/day, as adjunct therapy to the usual pneumonia treatment till the recovery of the disease.

Normalization of feeding refusal will be assessed by evaluating the child's ability to tolerate age-appropriate oral feeding without refusal over a 3-day observation period.

Blood samples will be collected, and CRP concentration will be expressed in milligrams per liter (mg/L).

LDH concentration will be reported in units per liter (U/L) from venous blood samples.

The serum C-reactive protein to albumin ratio (CRP/albumin ratio) will be calculated as a single composite outcome measure using laboratory values obtained from the same blood sample.

This outcome measures whether a participant undergoes any surgical intervention related to the study condition during the follow-up period. Surgical intervention is defined as any operative procedure performed under general or regional anesthesia, as documented in the medical record.

The outcome will be recorded as a binary variable (Yes/No) for each participant and summarized as the number and proportion of participants requiring surgical intervention.
