Relationship between Tuberculin Skin Test and COVID-19 Outcomes among Patients with COVID-19 in Zahedan, Iran.

Background: Ecological studies showed that countries with national Bacillus Calmette-Guerin (BCG) vaccination programs for tuberculosis prevention reported lower incidences of severe and fatal COVID-19 than countries without such programs. Several studies have demonstrated that the BCG vaccine can induce long-term trained Immunity in bone marrow progenitor cells. In this study, we tried to evaluate the relationship between tuberculin skin test results, BCG scar, and COVID-19 outcomes among patients with confirmed COVID-19.

The Prevalence of Absolute and Functional Iron Deficiency Anemia in New Cases of Smear-positive Pulmonary Tuberculosis and Their Sputum Conversion Rate at the End of Intensive Tuberculosis Treatment Phase.

About one third of the population is infected with tuberculosis (TB). On the other hand, iron deficiency is the most common micronutrient deficiency in the world. A number of studies have documented anemia in patients with TB, however, this study aimed to assess the prevalence of iron deficiency anemia (IDA) in patients with acid-fast bacilli (AFB) sputum smear-positive, and sputum conversion in these two groups of patients with absolute and functional IDA at the end of the second month of anti-TB therapy in Zahedan, Iran.

Dengue Fever as an Emerging Infection in Southeast Iran.

Dengue fever (DF) is a mosquito-borne acute viral disease presenting with hemorrhagic manifestations in severe cases. Southeast Iran is in close proximity to Pakistan, an endemic country for DF. This cross-sectional study was conducted in the Sistan and Baluchestan province in the southeast of Iran to investigate possibility of DF (immunoglobulin M [IgM], immunoglobulin G [IgG], and nonstructural protein 1 [NS1] antigen tests) in 60 clinically suspected patients (April 2013 to August 2015).

Novel, In-House, SYBR Green Based One-Step rRT-PCR: Rapid and Accurate Diagnosis of Crimean-Congo Hemorrhagic Fever Virus in Suspected Patients From Iran.

Background: The Crimean-Congo hemorrhagic fever (CCHF) virus causes severe disease in humans, with a high mortality rate. Since, there is no approved vaccine or specific treatment for CCHF, an early and accurate diagnosis, as well as reliable surveillance, is essential for case management and patient improvement.

Objectives: For this research, our aim was to evaluate the application of a novel SYBR Green based one-step real-time reverse-transcriptase polymerase chain reaction (rRT-PCR) assay for the in-house diagnosis of the CCHF virus.

Pharyngeal carriage rate of Neisseria meningitidis before and after the Hajj pilgrimage, in Zahedan (southeastern Iran), 2012.

Background/aim: The annual Hajj pilgrimage to Mecca, which attracts more than 3 million Muslim pilgrims from around the world, has played a role in the global spread of meningococcal infection. We aimed to compare pharyngeal carriage of Neisseria meningitidis in Hajj pilgrims before departure and after returning to Iran, Zahedan.

Materials And Methods: This prospective and cross-sectional study was conducted among Hajj pilgrims in Zahedan (southeast Iran) in 2012.

Acute Q fever among febrile patients in Zahedan, southeastern Iran.

Aim: So far, few studies have been conducted on Q fever in Iran. The objective of this study was to determine the frequency of acute Q fever in febrile patients admitted to Boo-Ali Hospital in Zahedan (southeastern Iran).

Materials And Methods: In this study, 105 febrile patients suspected ofhaving brucellosis were examined using indirect immunofluorescent assay kit for the detection of Coxiella burnetii IgM and IgG phase antibodies in their serum.

Prevalence of crimean-congo hemorrhagic Fever among high risk human groups.

Background: Crimean-Congo hemorrhagic fever (CCHF), an acute viral infection, is a zoonotic disease which is transmitted to humans by infected ticks, direct contact with fresh meat or blood of infected animals (usually domestic livestock), or direct contact with the blood or secretions of an infected person. Livestock handlers, skin processors, veterinary staff, livestock market workers, and other personnel engaged in jobs requiring some contact with animals and/or animal products are at high risk for CCHF. Most reported cases of this disease in Iran belong to butchers and slaughterhouse workers.

Factors associated with mortality in tuberculosis patients.

Background: Tuberculosis (TB) is one of the main causes of morbidity and mortality in different societies. Understanding factors leading to death following diagnosis of TB is important to predict prognosis in TB patients. The aim of this study was to identify common risk factors associated with death in patients with an in-hospital diagnosis of TB, in a city in Iran with the highest prevalence and incidence of TB in the country.

Efficacy of high-dose methylprednisolone in patients with Crimean-Congo haemorrhagic fever and severe thrombocytopenia.

Crimean-Congo haemorrhagic fever (CCHF) is an acute viral haemorrhagic disease that is now endemic in south eastern Iran. The most important factor associated with mortality is a platelet count of less than 50,000/mL. The purpose of this study is to compare treated cases with severe thrombocytopenia using ribavirin with high-dose methylprednisolone (HDMP) with patients receiving ribavirin without HDMP.

Can serum ferritin level predict disease severity in patients with crimean-congo hemorrhagic Fever?

Objective: Crimean-Congo hemorrhagic fever (CCHF) is an acute viral disease. Several factors have already been suggested to explain the pathogenesis as well as predict the disease severity. In our study we aim to investigate the role of serum ferritin level as a possible predicting factor of disease severity in these patients.

Association between tuberculosis and smoking.

Background: The association between smoking and tuberculosis (TB), which has been proven in multiple studies with different study population ethnicity, has not yet received sufficient attention in terms of TB control.

Objectives: The aim of the present study was to determine the association between TB and cigarette smoking in southeastern Iran, an endemic area for tuberculosis.

Patients And Methods: This prospective case-control study conducted at a University-Affiliated Hospital (Boo-Ali Hospital, Zahedan, and Southeastern Iran) from March 2007 to March 2012 enrolled 253 TB patients and 312 healthy controls.

Patho-TB test for the rapid diagnosis of pulmonary tuberculosis.

Background: Despite recent technologic improvements in identifying mycobacterium tuberculosis, we are still facing problems in rapid diagnosis of tuberculosis. The objective of this study is to determine the diagnostic value of a new rapid screening test (Patho-TB™) for diagnosis of pulmonary tuberculosis.

Methods: Between September 2006 to August 2007, 178 patients were enrolled in the study who were finally classified into two groups; a group of documented pulmonary tuberculosis (n = 67) and a group of non-tuberculous pulmonary infection (n = 111).
