Long-term health complications of chemical weapon exposure: a study on Halabja chemical attack survivors (Iraqi Kurds).

OBJECTIVE: In 1988, the Iraqi government used a range of chemical weapons (CWs) against the Iraqi Kurds of Halabja. Here, we aim to investigate the long-term health consequences in exposed survivors as they are not sufficiently studied. MATERIALS AND METHODS: This was a retrospective study conducted from November 2019 to May 2020 assessing the health status of all exposed Halabja chemical attack survivors compared to non-exposed people from the same area. RESULTS AND DISCUSSION: Two hundred thirty survivors and 240 non-exposed participants were enrolled in this study, with control participants matched to age, gender, and occupation. Among the survivors, females were more prevalent. The respiratory system was the most common single exposure route (83, 36.1%), with 138 (60%) of the survivors being exposed by multiple routes. The vast majority (88.7%) of survivors had activities of daily living (ADL) impairment. There was female predominance in mild and moderate cases, with more males in severe cases (p < 0.01). Respiratory and cardiac diseases were significantly more common in the survivors compared to the controls (p < 0.001). Survivors with multiple CW exposure routes had significantly higher rates of ADL impairment (p < 0.001) and cardiac disease, respiratory diseases, and miscarriage (p < 0.01), than those with a single exposure route. CONCLUSION: In this study comparing CW survivors with a local control population, a single, high-dose exposure to CWs was associated with significant increases in chronic respiratory and cardiac conditions, in addition to high rates of ADL impairment. Similar studies are needed in other, more recent CW survivor cohorts.

Chemical Weapons and public health: assessing impact and responses.

BACKGROUND: The recent use of Chemical Weapons (CWs) in armed conflicts and terror attacks highlights the importance of understanding their full impact in order to inform an effective response. This article argues that while the consequences of CWs on individual health have dominated our understanding of the impact of these weapons, far less attention has been directed to their impact on public health. METHODS: A review of the literature on the health impact of CWs was conducted, and two case studies of their use in urban settings were explored - Halabja in northern Iraq in 1988 and throughout Syria's ongoing conflict. RESULTS: The importance of considering the long-term health consequences of CW use and their impact on healthcare and health systems was demonstrated. CONCLUSIONS: This article highlights the importance of supporting future research on the topic and proposes a framework for assessing the public health impact of CW use.

Epidemiology and aetiology of the 2023 meningitis outbreak among children in Iraq.

Background: Meningitis is still a major public health challenge globally. Both the viral and bacterial forms of the disease have been reported worldwide. In 2023, around 200 children with suspected meningitis were admitted to hospital in Halabja Governorate, Iraq. No outbreak of meningitis had been reported previously in that region. Aims: To investigate the aetiology and epidemiology of meningitis among children in Halabja Governorate, Iraq, and expedite clinical management and prevention. Methodology: Blood and cerebrospinal fluid specimens were collected from 197 children admitted to Halabja Paediatric and Maternity Teaching Hospital from 1 March to 1 July 2023 and analysed. The sample t-test was used to compare the haematological, serological and biochemical characteristics of the samples. Results: The majority (76.6%) of the children were aged 2-9 years and 54% were males. The clinical manifestations of the disease were fever (100.0%), headache (89.0%), vomiting (85.7%), and photophobia (72.4%); none of the children had convulsions. The mean values for both neutrophil count and C-reactive protein were statistically significantly raised (P < 0.05) and the red blood cells, white blood cells and neutrophil counts, and lactate dehydrogenase values were statistically significantly raised (P < 0.05). The causative organism was enterovirus (98.5%), with sporadic cases of streptococcal meningitis (1.5%). All the patients recovered fully. Conclusion: The rapid diagnosis of the disease was crucial to the therapeutic and prevention control measures for the outbreak. Although it is still unclear how and where this outbreak started, contaminated drinking water and transmission among children in nurseries and schools are suspected. Further investigations are recommended to determine the source of the enterovirus and identify the virus species and serotypes.

Respiratory function after 30+ years following sulfur mustard exposure in survivors in Sweden.

Background: Sulfur mustard (SM) exposure causes acute and chronic respiratory diseases. The extent of small airway dysfunction (SAD) in individuals exposed to SM is unclear. This study evaluated and compared SAD in SM-exposed and SM-unexposed participants using noninvasive lung function tests assessing small airway function. Methods: This retrospective cohort study involved SM-exposed (n = 15, mean age: 53 ± 8 years) and SM-unexposed (n = 15, mean age: 53 ± 7 years) Kurdish-Swedish individuals in Sweden. Small airway resistance and reactance were assessed using impulse oscillometry (IOS). Nitrogen (N2) multiple breath washout (MBW) was employed to assess lung ventilation heterogeneity. The gas-exchanging capacity of the lungs was assessed using the diffusing capacity of the lungs for the carbon monoxide (DLCO) test. Lung function outcomes were reported as absolute values and z-scores. Group comparisons were performed using the Mann-Whitney U test. Results: No statistically significant differences in age, height, or body mass index were observed between the two groups. IOS showed significantly increased small airway resistance, while N2MBW exhibited significantly increased global and acinar ventilation heterogeneity in SM-exposed individuals compared to that in unexposed individuals. SAD was identified in 14 of 15 SM-exposed individuals, defined as at least one abnormal IOS difference between resistance at 5 and 20 Hz (R5-R20) and/or area of reactance (AX) or N2MBW lung's acinar zone (Sacin), and DLCO adjusted to the alveolar volume (DLCO/VA) outcome. Of these 14 individuals, only 5 demonstrated concordant findings across the IOS and N2MBW tests. Conclusion: Exposure to SM was positively associated with long-term impairment of respiratory tract function in the small airways in the majority of the previously SM-exposed individuals in the present study. Furthermore, both IOS and N2MBW should be employed to detect SAD in SM-exposed survivors as they provide complementary information. Identifying and characterizing the remaining pathology of the small airways in survivors of SM exposure is a first step toward improved treatment and follow-up.

From Holocaust to Anfal: The impact of genocide and cross-generational trauma on the mental health of Kurds.

Genocide attempts are among the most severe traumatic events that are transmitted across generations. However, it may also prove the strength and survivability as well as the vulnerability of the targeted group. Anfal and chemical attacks on Halabja on Iraqi Kurds that targeted their annihilation had a devastating impact. Many survivors and their generations are still dealing with their effects on psychological disorders such as posttraumatic stress disorder (PTSD) and depression. To address the psychological effects of these tragic events on survivors and their generations and propose the actions to be taken, this article explores the psychological trauma and problems caused by attempted genocide and chemical attacks in the case of Anfal campaign. These effects require more research to fully understand the long-term effects of these tragedies, as well as support and provision of comprehensive psychological and mental health interventions to their survivors and generations.
