Traditional Remedy Sagwa as a Risk Factor for Severe Morbidity and Mortality in Iraqi Infants with Acute Diarrhea. A Case–Control Study

Introduction

Diarrhea and the complications it produce are a major cause of morbidity and mortality in children, especially in the developing countries being second most common cause of death in children less than five years old worldwide. Diarrhea is responsible for 2.4 million deaths every year.^1,2 In Iraq, diarrhea is the main cause of 70% of deaths among children, and yearly every child may have an average of 6 episodes of diarrhea.³ Acute gastroenteritis may be infectious or non-infectious.⁴ Morbidity and mortality of gastroenteritis are affected by many factors like antibiotics misuse; however, the herbal remedy (Sagwa) use is one of the prominent factors in Iraq.⁵

Using herbal medicine and supplements has been higher over the last three decades so that approximately 80% of the global population rely on them. A majority of these products are unlicensed, and their consumption is unregulated.^6,7 Their potential toxicity may include neurotoxic, hepatotoxic nephrotoxic and cardiotoxic effects.⁸ As many as 80% of individuals in Africa consume herbal preparations for health problems, while in China, herbal medicine accounts for 30-50% of all medicines consumed.⁶

Certain herbal folk remedies are popularly used mainly in rural areas in Iraq & other countries. These include plants, roots, seeds and berries which are frequently used for treating diseases. Sagwa is one of these main remedies in Iraq. It is commonly used among people from low socioeconomic classes with limited literacy to treat neonates, infants and children with diarrhea and abdominal discomfort.⁵ Sagwa is made of a mixture of boiled animal parts of urchin, lomotil (diphenoxylate and atropine), tar, cow feces & rose water. This is commonly used by some midwives & elderly woman in rural areas as part of traditional knowledge & wrong beliefs for treating prolonged diarrheal diseases despite of its known harmful effects.¹ After shaving the infant’s head, Sagwa mixture is put on it and left for at least 24 hours to make sure all the substances will be absorbed. This folk remedy is highly dangerous and can cause serious complications and even death in infants.^1,9–12

Adequate data on Sagwa’s constituents -such as its mechanism of action, contraindications, adverse effects, and drug interactions- is absent, rendering it inherently risky. Some people prefer herbal remedies since they consider conventional medicines are industrially prepared.⁶ The reports received by the Iraqi pharmacovigilance center from many Iraqi pediatric hospitals show that analysis of Sagwa showed that its made of many toxic organic and inorganic substances like mercury, arsenic, animal skin and lead. More than half of the adverse events were gastrointestinal and in about half of them, the presentation was life threatening. So, this dangerous practice is worthy to be shed light on and given enough attention so as to raise the awareness of people about its detrimental results.⁵ This study was conducted to determine the morbidity and mortality of Sagwa use in acute gastroenteritis in infants and associated factors.

Patients and methods

Results

A total of 100 infants were enrolled, comprising 50 cases and 50 controls. There were no significant differences between cases and controls with respect to age (p=0.9) or gender (p=0.9) ( Table 1). The process of enrolment and classification of participants into cases and controls is illustrated in Figure 1.

Figure 1. Flow diagram of study population.

A significant association was observed between residence and Sagwa exposure, with cases more likely to live in rural areas compared with controls (p=0.03). Maternal education was also significantly associated, as cases were more likely to have mothers who were not educated (p=0.007). A highly significant association was found between grandmother responsibility for caregiving and Sagwa exposure (p<0.001), whereas grandmother’s educational level did not differ significantly between cases and controls (p=0.2) ( Table 2).

Regarding clinical outcomes, severe dehydration was significantly more common among cases compared with controls (p=0.01). Convulsions were strongly associated with Sagwa exposure, occurring only in cases (p<0.001). Mortality was also significantly higher among cases than controls (p=0.05). In contrast, no significant differences were noted between the two groups regarding renal failure (p=0.1), dialysis (p=0.3), or coma (p=0.6) ( Table 3). These contrasts in outcomes are summarized visually in Figure 2, which highlights higher rates of severe dehydration, convulsions, and mortality among cases.

When clinical outcomes were analyzed according to routes of Sagwa administration, convulsions and renal failure were significantly associated with combined oral and scalp administration (p<0.001 for both). However, dehydration severity did not differ significantly by administration route (p=0.1) ( Table 4).

Discussion

This study shows that using Sagwa is really a significant public health problem in Fallujah like other areas in Iraq. The study shows no significant differences in the age between cases ((Sagwa-exposed infants) and controls though in the both groups age of less than one month was more common in contrast to another Iraqi study where age of more than six months was more common.⁶ Although in both groups male was more common but was not significantly different in line with other studies.^5,6,13 Consumption of Sagwa was more frequent among children whose mothers had a lower educational attainment, consistent with findings in Iraq.^14,15 Mothers with poor education have no proper ideas about how to treat diarrhea and are more susceptible to being persuaded by others to administer Sagwa, unaware of its dangers to their children. The grandmothers were to blame in most cases without any significant effect of their educational level since they tend to believe in herbal medicine and consider it more effective than medications prescribed by doctors and this reinforces the role of cultural and intergenerational influence in perpetuating this practice. This relationship is clearly demonstrated in Figure 1, which shows the case–control distribution of Sagwa-exposed and non-exposed infants.

Dehydration was found to be significantly different between cases and controls with predominance of moderate dehydration in cases similar to other studies.^6,16

Clinically, Sagwa exposure is significantly associated with convulsions, severe dehydration, and higher mortality. These outcomes agree with documented evidence of Sagwa’s toxicity caused by heavy metal content such as lead, cadmium, and mercury.¹⁰

Several studies found severe neurological consequences of Sagwa use. Similarly, an Iraqi prospective case–control study from Diyala reported central nervous system (CNS) complications in 43% of Sagwa-exposed children including altered consciousness, seizures and coma as compared to controls. Mortality in the Sagwa group reached 9%.⁶ Likewise, another Iraqi study from Baghdad did pharmacovigilance analysis of 43 individual case safety reports and concluded about half of cases had life-threatening complications with neurological signs being prominent upon presentation. Toxicology revealed hazardous substances like lead, arsenic, mercury, and animal-derived material that all are likely to induce acute neurotoxicity.⁵ Our findings are illustrated in Figure 2, which highlights that convulsions, severe dehydration, and mortality were markedly more frequent among cases compared with controls.

Renal failure and need for dialysis are not statistically significant in our study but were present among infants who received Sagwa, and this suggests potential underestimation of its toxicity mostly due to sample limitations. Another study reported dialysis-requiring renal involvement after Sagwa use,¹⁷ and a study found renal complications in 49% of Sagwa-exposed children with metabolic derangements in 83% indicating multi-system involvement.⁶

Our study found a high mortality of 12% among Sagwa-exposed infants as compared to 2% in controls with acute diarrhea which even higher than another Iraqi study from Diyala where it was 9%.⁶ Furthermore, a cross-sectional observational study from Baghdad found that among Sagwa-exposed children mortality was 58.3% compared to only 2.1% in the non-using group. Additionally, 25% of those who survivors had significant complications.¹⁸

The main limitations of our study are its single-center setting, cross-sectional design, its dependence on self-reported data, and the presence of other confounders that limit how confidently we can attribute mortality and complications solely to Sagwa use.

In conclusion, Sagwa use in infants with diarrhea is dangerous and contributes to morbidity and mortality which are preventable. We recommend focusing on culturally sensitive education that targets mothers and grandmothers in rural areas and imposing stricter regulation of hazardous traditional remedies by authorities.
