Background:
Infection with Human Immune deficiency Virus (HIV) is a growing problem in developing countries. Among HIV infected cases, respiratory complications are common, dissimilar in different setting and their diagnosis is challenging. The aim of this study was to determine the spectrum of infectious and non-infectious pulmonary complications among HIV infected patients.
Materials And Methods:
The retrospective study was done among 710 HIV infected patients admitted in Masih Daneshvari Hospital, National Research Institute of Tuberculosis and Lung Diseases, Tehran, Iran from January 2003 to March 2017. Demographic, clinical, radiologic and laboratory data of 836 episodes of pulmonary complications were reviewed and final diagnosis were extracted.
Results:
Mean of CD4 cell count was 90±131 ×106 cells/L. Definite etiology was found for 653 episodes (78.1%) of pulmonary complications. Infectious respiratory diseases were clearly more common than non-infectious etiologies, 86.1 and 7.6%, respectively. Pulmonary tuberculosis, as the leading cause, involved 542 cases (64.8%) and Pneumocystis jiroveci (P. jiroveci) was the second infectious agent that was found in 111 cases (13.2%). Among non- infectious causes, bronchiectasis and Chronic Obstructive Pulmonary Disease (COPD) exacerbation were on the top of the list, 21 of 64 (32.8%) and 18 0f 64 (28.1%), respectively. Many patients had more than one etiology. P. jiroveci had the highest tendency for dual infections (43 episodes).
Conclusion:
Pulmonary complications, especially infections are common among HIV cases in Iran, among them tuberculosis is the most common. Respiratory problems may be the first presentation of HIV infection. Clinicians should be aware about the risk of dual infections. Screening for HIV among all tuberculosis cases and vice versa is recommend.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...
